  • do I need to close an audio Clip?

    - by Michael
    have an application that processes real-time data and is supposed to beep when a certain event occurs. The triggering event can occur multiple times per second, and if the beep is already playing when another event triggers the code is just supposed to ignore it (as opposed to interrupting the current beep and starting a new one). Here is the basic code: Clip clickClip public void prepareProcess() { super.prepareProcess(); clickClip = null; try { clipFile = new File("C:/WINDOWS/Media/CHIMES.wav"); ais = AudioSystem.getAudioInputStream(clipFile); clickClip = AudioSystem.getClip(); clickClip.open(ais); fileIsLoaded = true; } catch (Exception ex) { clickClip = null; fileIsLoaded = false; } } public void playSound() { if (fileIsLoaded) { if ((clickClip==null) || (!clickClip.isRunning())) { try { clickClip.setFramePosition(0); clickClip.start(); } catch (Exception ex) { System.out.println("Cannot play click noise"); ex.printStackTrace(); } } } The prepareProcess method gets run once in the beginning, and the playSound method is called every time a triggering event occurs. My question is: do I need to close the clickClip object? I know I could add an actionListener to monitor for a Stop event, but since the event occurs so frequently I'm worried the extra processing is going to slow down the real-time data collection. The code seems to run fine, but my worry is memory leaks. The code above is based on an example I found while searching the net, but the example used an actionListener to close the Clip specifically "to eliminate memory leaks that would occur when the stop method wasn't implemented". My program is intended to run for hours so any memory leaks I have will cause problems. I'll be honest: I have no idea how to verify whether or not I've got a problem. I'm using Netbeans, and running the memory profiler just gave me a huge list of things that I don't know how to read. This is supposed to be the simple part of the program, and I'm spending hours on it. Any help would be greatly appreciated! Michael

  • How should I convert a physical drive to a VHD for use with VirtualPC?

    - by RBerteig
    I have the hard disks from a PC that was happily running Windows Me until is it suffered an unknown hardware failure. The drives are intact, and can be mounted and read on other PCs. We have data backups, but there is licensed software installed that may not be possible to migrate to newer versions running on a more modern platform making the idea of just booting a virtual image attractive. Is it possible to make VHDs from the drives such that I can boot them in VirtualPC? If not VirtualPC, would it be possible in any other virtualization tool? Edit: Some more details.... The system was running Windows Me, but upgraded from Windows 95 (or possibly 98). It can't have been more than a Pentium II, but I will have to look at the motherboard to confirm that. There were no "exotic" devices installed, and nothing beyond the usual legacy stuff that would need to survive into a virtual machine. The licensed software did not have a dongle, so I won't need to worry about virtualizing a physical dongle of some kind. Licenses were probably died to the disk serial number. There were two HDs, both IDE. The boot disk is about 6GB, and the spare data disk is 12GB, but nearly empty. I have a small bias in favor of VirtualPC just because its free and I've used it successfully in the past. But this is a good excuse to revisit the state of the art. I do know from direct experience that it is possible to install and boot DOS 5.0 and Win95 in VirtualPC, but the VM extensions weren't available so the experience isn't as seamless as I would have liked. A very old DirectX game that failed miserably under XP SP2 runs really nicely on that VM, and actually plays better in a lot of ways than it did on period hardware, so that gives me hope that this is possible. Edit 2: Well, I'm closer than I was when I asked... so thanks to all for helpful suggestions and hints to what I should be trying. I used WinImage to copy the disks, and VirtualPC 2007 to attempt to boot. So far, I have it booting in safe mode, but hanging with a black screen otherwise. I strongly suspect that the copy of Artisoft Lantastic 8.0 (anyone else remember them?) that is still installed for networking with even older PCs that mostly don't exist any more is the culprit there. In my infinite free time, I will try to resolve the differences between a Safe Mode boot and a normal boot, and feel that it is likely to yield to pressure. I'd accept more than one answer if I could... this isn't as black and white a question as the one accepted answer convention assumes.

  • Failed to obtain JDBC Driver for MySQL under Tomcat environment

    - by Michael Mao
    Hi all: I've been trying to obtain the Driver class for JDBC connection to MySQL. The workstation is running on Linux, Fedora 10. I have manually set up the classpath variable for Java by CLI like this: bash-3.2$ echo $CLASSPATH /home/cmao/public_html/jsp/mysql-connector-java-5.1.12-bin.jar This shows that I've added the lastest mysql connection jar archive to my CLASSPATH variable. I've created a test JSP page which can be found here And source code for this page is: <%@page language="java"%> <%@page import="java.sql.*"%> <%@page import="java.util.*"%> <html> <head> <title>UTS JDBC MySQL connection test page</title> </head> <body> <% Connection con = null; out.print("Java version is : " + System.getProperty("java.version") + "<br />"); out.print("Tomcat version is : " + application.getServerInfo() + "<br />"); out.print("Servlet version is: " + application.getMajorVersion() + "<br />"); out.print("JSP version is : " + JspFactory.getDefaultFactory().getEngineInfo().getSpecificationVersion() +"<br />"); //out.print("Java classpath is : " + System.getProperty("java.class.path")+ "<br />"); //out.print("JSP classpath is : " + appliaction.getAttribute("org.apache.catalina.jsp_classpath") + "<br />"); //out.print("Tomcat classpath is : " + System.getProperty("org.apache.tomcat.common.classpath") + "<br />"); try { Class c = Class.forName("com.mysql.jdbc.Driver"); } catch(Exception e) { out.println("Error! Failed to obtain JDBC driver for MySQL... Missing class \"com.mysql.jdbc.Driver\"<br />"); } %> </body> </html> None of those commented out line would work, various Jsper Expetions would be thrown. You can check those Error pages from the following links: classpath Error page catalina Error page tomcat Error page It seems, from my limited knowledge of JSP and Servlet, the Tomcat environment "ignores" my Java CLASSPATH? In which case I cannot configure the MySQL JDBC package to let my Servlets(a JSP is but a Servlet anyway) work. I am not sure how to fix this issue. would it be better if I use an IDE like Eclipse or NetBeans and create a real Java "web app" so that everything can be "self-configured" by the usage of a web.config XML configuration file? So that I can certainly bypass this Tomcat environment restriction? Many thanks for the suggestions in advance.

  • Bypassing "Found New Hardware Wizard" / Setting Windows to Install Drivers Automatically

    - by Synetech inc.
    Hi, My motherboard finally died after the better part of a decade, so I bought a used system. I put my old hard-drive and sound-card in the new system, and connected my old keyboard and mouse (the rest of the components—CPU, RAM, mobo, video card—are from the new system). I knew beforehand that it would be a challenge to get Windows to boot and install drivers for the new hardware (particularly since the foundational components are new), but I am completely unable to even attempt to get through the work of installing drivers for things like the video card because the keyboard and mouse won't work (they do work, in the BIOS screen, in DOS mode, in Windows 7, in XP's boot menu, etc., just not in Windows XP itself). Whenever I try to boot XP (in normal or safe mode), I get a bunch of balloons popping up for all the new hardware detected, and a New Hardware Found Wizard for Processor (obviously it has to install drivers for the lowest-level components on up). Unfortunately I cannot click Next since the keyboard and mouse won't work yet because the motherboard drivers (for the PS/2 or USB ports) are not yet installed. I even tried a serial mouse, but to no avail—again, it does work in DOS, 7, etc., but not XP because it doesn't have the serial port driver installed. I tried mounting the SOFTWARE and SYSTEM hives under Windows 7 in order to manually set the "unsigned drivers warning" to ignore (using both of the driver-signing policy settings that I found references to). That didn't work; I still get the wizard. They are not even fancy, proprietary, third-party, or unsigned drivers. They are drivers that come with Windows—as the drivers for CPU, RAM, IDE controller, etc. tend to be. And the keyboard and mouse drivers are the generic ones at that (but like I said, those are irrelevant since the drivers for the ports that they are connected to are not yet installed). Obviously at some point in time over the past several years, a setting got changed to make Windows always prompt me when it detects new hardware. (It was also configured to show the Shutdown Event Tracker on abnormal shutdowns, so I had to turn that off so that I could even see the desktop.) Oh, and I tried deleting all of the PNF files so that they get regenerated, but that too did not help. Does anyone know how I can reset Windows to at least try to automatically install drivers for new hardware before prompting me if it fails? Conversely, does anyone know how exactly one turns off automatic driver installation (and prompt with the wizard)? Thanks a lot.

  • JPA Inheritance and Relations - Clarification question

    - by Michael
    Here the scenario: I have a unidirectional 1:N Relation from Person Entity to Address Entity. And a bidirectional 1:N Relation from User Entity to Vehicle Entity. Here is the Address class: @Entity public class Address implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO) privat Long int ... The Vehicles Class: @Entity public class Vehicle implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @ManyToOne private User owner; ... @PreRemove protected void preRemove() { //this.owner.removeVehicle(this); } public Vehicle(User owner) { this.owner = owner; ... The Person Class: @Entity @Inheritance(strategy = InheritanceType.JOINED) @DiscriminatorColumn(name="PERSON_TYP") public class Person implements Serializable { @Id protected String username; @OneToMany(cascade = CascadeType.ALL, orphanRemoval=true) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME"), inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) protected List<Address> addresses; ... @PreRemove protected void prePersonRemove(){ this.addresses = null; } ... The User Class which is inherited from the Person class: @Entity @Table(name = "Users") @DiscriminatorValue("USER") public class User extends Person { @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; ... When I try to delete a User who has an address I have to use orphanremoval=true on the corresponding relation (see above) and the preRemove function where the address List is set to null. Otherwise (no orphanremoval and adress list not set to null) a foreign key contraint fails. When i try to delete a user who has an vehicle a concurrent Acces Exception is thrown when do not uncomment the "this.owner.removeVehicle(this);" in the preRemove Function of the vehicle. The thing i do not understand is that before i used this inheritance there was only a User class which had all relations: @Entity @Table(name = "Users") public class User implements Serializable { @Id protected String username; @OneToMany(mappedBy = "owner", cascade = {CascadeType.PERSIST, CascadeType.REMOVE}) private List<Vehicle> vehicles; @OneToMany(cascade = CascadeType.ALL) @JoinTable(name = "USER_ADDRESS", joinColumns = @JoinColumn(name = "USERNAME") inverseJoinColumns = @JoinColumn(name = "ADDRESS_ID")) ptivate List<Address> addresses; ... No orphanremoval, and the vehicle class has used the uncommented statement above in its preRemove function. And - I could delte a user who has an address and i could delte a user who has a vehicle. So why doesn't everything work without changes when i use inheritance? I use JPA 2.0, EclipseLink 2.0.2, MySQL 5.1.x and Netbeans 6.8

  • Start a software company offshore

    - by Mascarpone
    Hello Everybody, I own a small, very young, EU based (Italy) company, and among other things, we sell IT solutions. I have a degree in applied mathematics, and I mainly deal with user interfaces, embedded systems, automation and web applications. You can say that I'm an enlightened entrepreneur because I work only with open source software (OS, IDE, I release under BSD , ... everything is free as in freedom), I give high importance to post sales services and customer satisfaction, plus I think I'm the best boss someone could desire (LOL), as I have google in mind when I think about IT workers rights. But the most beautiful thing is that, although everybody advised us not to use open source, is that we are quite profitable!!! (for the sixth trimester in a row). Now I offshore most of the work to an Indian company. I divide the work in modules and I outsource the longer or more trivial ones. I spend a lot of time defining the specifications and I leave the hard work to them. Using productivity bonuses, a lot of prototypes and third-party audits I think that my software has reached a very good quality level. I would like to start my own software development company, in order to improve control over process and cut costs. Obviously I can't afford the cost of labor in the EU, so I thought about opening a company in Asia. What I need Is: 1) Cheap labor - I can afford to give productivity bonuses and higher than average wages and stay profitable just because labor is cheap. 2) Many talents - I need a good level of tertiary education, and a good number of graduates, so I can hire junior developers and train and teach them according to my needs and philosophies (e.g.: open source mind) 3) Good infrastructure - buildings, transport, internet, .... everything that a company might need. I thought about 3 possible candidates: 1) India - I already work with indian people, I know that they are realiable and speak a good english. Big cities are too expensive, but maybe a small city like lucknow http://en.wikipedia.org/wiki/Lucknow could suits my needs. 2) China - They say it's cheaper than India, but I everytime I worked with a chineese company the language was a big barrier. They work hard, are somewhat skilled and cheap but maybe it's a risky path. Plus I feel a little uncofortable with their lack of human rights. 3) Philippines - Same as china: cheaper than india, but maybe less educated. Where do you think it's the best place to start a software company? Any reading or book to advise? thank you very much

  • Computer freezes +/- 30 seconds, suspicion on SSD

    - by Robert vE
    My computer freezes for about 30 seconds, this happens occasionally. When it happens I can still move the mouse, sometimes even alternate between tabs in google chrome. If I try to open windows explorer nothing happens. Also chrome rapports "waiting for cache". It also happens in starcraft II, during which the sounds loops. I have made a Trace as this topic describes: How do I troubleshoot a Windows 7 freeze or slowness? Trace: https://docs.google.com/open?id=0B_VkKdh535p6NklhSDdBLURUMnc I have looked at it, but I couldn't figure it out. My system specs are: AMD Athlon X4 651 Asus Ati HD6670 ADATA SSD sp900 Asus f1a55 mainboard 4 GB crucial 1333 ram 500 watt atx ps I'm running Windows 7, fully updated. Any help is much appreciated. Update: I tried something before your reply that may have helped the problem. I don't know for sure if it has, it's too soon to tell. A bit of history first. I had problems installing win7 on my ssd from the start. In IDE mode it worked, but I had the same problems as above. AHCI was a total fail, with it on before install as well as turning it on after install (including tweaking register). I didn't bother installing the AMD chipset/AHCI as it was reported to have no TRIM function and thus make problems worse. Eventually I did install the AMD SMbus driver as the stability issues were driving me crazy. It worked, no more issues, until I installed some extra drivers and software. Audio/LAN/ASUS suite, I don’t see the relation, but somehow it screwed up my system again. As a last effort I posted here on this site. After which the thought occurred to me turn on AHCI again as by now I had all necessary drivers installed anyway. (plus all windows updates downloaded/installed in the meantime) I did and stability didn’t seem great the first few reboots, but eventually everything seemed to work great. I tried to play starcraft II – an almost guaranteed freeze before – and I had no problems. I’m basically crossing my fingers and hope the problem is gone for good. I still think it has something to do with my SSD. In my research into the problem I noticed a lot of these issues with sandforce 2281 firmware, the exact same firmware I have. People reported the same problem that I had, freezes. Additionally they reported that during a freeze the hdd light stayed on, I noticed after I read this that this happened with my computer as well. None of this is conclusive evidence that my SSD is really to fault, but it is suspicious. And why turning on AHCI would fix it I don’t know. Thank you Tom for taking a look, if the problem returns I will certainly do what you advised.

  • Linux Software RAID1 Rebuild Completes, but after reboot, its degraded again

    - by zimmy6996
    I have been beating my head with an issue here, and I'm now turning to the internet for help. I have a system running Mandrake Linux, with the following configuration: /dev/hda - This is a IDE drive. Has some partitions on it that boot the system and make up most of the file system. /dev/sda - This is drive 1 of 2 for a software raid /dev/md0 /dev/sdb - This is drive 2 of 2 for a software raid /dev/md0 md0 gets mounted but fstab as /data-storage, so it is not critical to the systems ability to boot. We can comment it out of fstab, and the system works just fine either way. The problem is, we have a failed sdb drive. So I shut the box down, and have pulled the failed disk and installed a new disk. When the system boots up, /proc/mdstat shows only sda as part of the raid. I then run the various command to rebuild the RAID to /dev/sdb. Everything rebuilds correctly, and upon completion, you look at /proc/mdstat and it shows 2 drives sda1(0) and sdb1(1). Everything looks great. Then you reboot the box ... UGH!!! Once rebooted, sdb is missing again from the RAID. It is like the rebuild never happened. I can walk through the commands to rebuild it again, and it will work, but again, after reboot, the box seems to make sdb just vanish! The real odd thing is, if after reboot, I pull sda out of the box, and try to get the system to load with the rebuilt sdb drive in the system, and when I do, the system actually throws and error just after grub, and says something about drive error, and the system has to shut down. Thoughts??? I'm starting to wonder if grub has something to do with this mess. That the drive isn't being setup within grub to be visible at boot? This RAID array isn't necessary for the system to boot, but when the replacement drive is in there, without SDA it won't boot system, so it makes me believe there is something to that. On top of that, there just seems to be something wonky here the drive falling off of RAID after reboot. I've hit the point of pounding my head on the keyboard. Any help would be greatly appreciated!!!

  • Logitech Optical Mouse Frozen In Middle of Windows XP Pro Screen

    - by Code Sherpa
    Hi. I have a Logitech Optical Mouse/Keyboard. I have been using them just fine with the system drivers for almost a year now. I recently updated my Kaspersky software and rebooted. Now the mouse is frozen in the middle of my screen. I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer. Things I know / have tried: When I boot on the problem computer, I am able to use the keyboard, but not the mouse. I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter. I bought new batteries for the mouse and that didn't matter. I have tried the mouse/keyboard on another computer and the mouse works just fine there. My suspicion is that the Kaspersky install has overwritten a driver of some sort. Things I have not done (and would appreciate detailed steps if you feel this is the way to go): 1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall. Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device? 2) Update my BIOS. Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version. Thanks for your help.

  • How much time should it take to find the sum of all prime numbers less than 2 million?

    - by Shahensha
    I was trying to solve this Project Euler Question. I implemented the sieve of euler as a helper class in java. It works pretty well for the small numbers. But when I input 2 million as the limit it doesn't return the answer. I use Netbeans IDE. I waited for a lot many hours once, but it still didn't print the answer. When I stopped running the code, it gave the following result Java Result: 2147483647 BUILD SUCCESSFUL (total time: 2,097 minutes 43 seconds) This answer is incorrect. Even after waiting for so much time, this isn't correct. While the same code returns correct answers for smaller limits. Sieve of euler has a very simple algo given at the botton of this page. My implementation is this: package support; import java.util.ArrayList; import java.util.List; /** * * @author admin */ public class SieveOfEuler { int upperLimit; List<Integer> primeNumbers; public SieveOfEuler(int upperLimit){ this.upperLimit = upperLimit; primeNumbers = new ArrayList<Integer>(); for(int i = 2 ; i <= upperLimit ; i++) primeNumbers.add(i); generatePrimes(); } private void generatePrimes(){ int currentPrimeIndex = 0; int currentPrime = 2; while(currentPrime <= Math.sqrt(upperLimit)){ ArrayList<Integer> toBeRemoved = new ArrayList<Integer>(); for(int i = currentPrimeIndex ; i < primeNumbers.size() ; i++){ int multiplier = primeNumbers.get(i); toBeRemoved.add(currentPrime * multiplier); } for(Integer i : toBeRemoved){ primeNumbers.remove(i); } currentPrimeIndex++; currentPrime = primeNumbers.get(currentPrimeIndex); } } public List getPrimes(){ return primeNumbers; } public void displayPrimes(){ for(double i : primeNumbers) System.out.println(i); } } I am perplexed! My questions is 1) Why is it taking so much time? Is there something wrong in what I am doing? Please suggest ways for improving my coding style, if you find something wrong.

  • TFS 2010 SDK: Connecting to TFS 2010 Programmatically&ndash;Part 1

    - by Tarun Arora
    Technorati Tags: Team Foundation Server 2010,TFS 2010 SDK,TFS API,TFS Programming,TFS ALM   Download Working Demo Great! You have reached that point where you would like to extend TFS 2010. The first step is to connect to TFS programmatically. 1. Download TFS 2010 SDK => http://visualstudiogallery.msdn.microsoft.com/25622469-19d8-4959-8e5c-4025d1c9183d?SRC=VSIDE 2. Alternatively you can also download this from the visual studio extension manager 3. Create a new Windows Forms Application project and add reference to TFS Common and client dlls Note - If Microsoft.TeamFoundation.Client and Microsoft.TeamFoundation.Common do not appear on the .NET tab of the References dialog box, use the Browse tab to add the assemblies. You can find them at %ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE\ReferenceAssemblies\v2.0. using Microsoft.TeamFoundation.Client; using Microsoft.TeamFoundation.Framework.Client; using Microsoft.TeamFoundation.Framework.Common;   4. There are several ways to connect to TFS, the two classes of interest are, Option 1 – Class – TfsTeamProjectCollectionClass namespace Microsoft.TeamFoundation.Client { public class TfsTeamProjectCollection : TfsConnection { public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection); public TfsTeamProjectCollection(Uri uri); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials); public TfsTeamProjectCollection(Uri uri, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsTeamProjectCollection(RegisteredProjectCollection projectCollection, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsTeamProjectCollection(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public TfsConfigurationServer ConfigurationServer { get; internal set; } public override string Name { get; } public static Uri GetFullyQualifiedUriForName(string name); protected override object GetServiceInstance(Type serviceType, object serviceInstance); protected override object InitializeTeamFoundationObject(string fullName, object instance); } } Option 2 – Class – TfsConfigurationServer namespace Microsoft.TeamFoundation.Client { public class TfsConfigurationServer : TfsConnection { public TfsConfigurationServer(RegisteredConfigurationServer application); public TfsConfigurationServer(Uri uri); public TfsConfigurationServer(RegisteredConfigurationServer application, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials); public TfsConfigurationServer(Uri uri, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider); public TfsConfigurationServer(RegisteredConfigurationServer application, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public TfsConfigurationServer(Uri uri, ICredentials credentials, ICredentialsProvider credentialsProvider, IdentityDescriptor identityToImpersonate); public override CatalogNode CatalogNode { get; } public override string Name { get; } protected override object GetServiceInstance(Type serviceType, object serviceInstance); public TfsTeamProjectCollection GetTeamProjectCollection(Guid collectionId); protected override object InitializeTeamFoundationObject(string fullName, object instance); } }   Note – The TeamFoundationServer class is obsolete. Use the TfsTeamProjectCollection or TfsConfigurationServer classes to talk to a 2010 Team Foundation Server. In order to talk to a 2005 or 2008 Team Foundation Server use the TfsTeamProjectCollection class. 5. Sample code for programmatically connecting to TFS 2010 using the TFS 2010 API How do i know what the URI of my TFS server is, Note – You need to be have Team Project Collection view details permission in order to connect, expect to receive an authorization failure message if you do not have sufficient permissions.

Programmatically query TFS 2010 using the TFS SDK for all Team Project Collections and retrieve all Team Projects and output the display name and description of each team project. CatalogNode catalogNode = configurationServer.CatalogNode; ReadOnlyCollection<CatalogNode> tpcNodes = catalogNode.QueryChildren( new Guid[] { CatalogResourceTypes.ProjectCollection }, false, CatalogQueryOptions.None); // tpc = Team Project Collection foreach (CatalogNode tpcNode in tpcNodes) { Guid tpcId = new Guid(tpcNode.Resource.Properties["InstanceId"]); TfsTeamProjectCollection tpc = configurationServer.GetTeamProjectCollection(tpcId); // Get catalog of tp = 'Team Projects' for the tpc = 'Team Project Collection' var tpNodes = tpcNode.QueryChildren( new Guid[] { CatalogResourceTypes.TeamProject }, false, CatalogQueryOptions.None); foreach (var p in tpNodes) { Debug.Write(Environment.NewLine + " Team Project : " + p.Resource.DisplayName + " - " + p.Resource.Description + Environment.NewLine); } }   Output   You can download a working demo that uses TFS SDK 2010 to programmatically connect to TFS 2010.

  • Conversation as User Assistance

    - by ultan o'broin
    Applications User Experience members (Erika Web, Laurie Pattison, and I) attended the User Assistance Europe Conference in Stockholm, Sweden. We were impressed with the thought leadership and practical application of ideas in Anne Gentle's keynote address "Social Web Strategies for Documentation". After the conference, we spoke with Anne to explore the ideas further. Anne Gentle (left) with Applications User Experience Senior Director Laurie Pattison In Anne's book called Conversation and Community: The Social Web for Documentation, she explains how user assistance is undergoing a seismic shift. The direction is away from the old print manuals and online help concept towards a web-based, user community-driven solution using social media tools. User experience professionals now have a vast range of such tools to start and nurture this "conversation": blogs, wikis, forums, social networking sites, microblogging systems, image and video sharing sites, virtual worlds, podcasts, instant messaging, mashups, and so on. That user communities are a rich source of user assistance is not a surprise, but the extent of available assistance is. For example, we know from the Consortium for Service Innovation that there has been an 'explosion' of user-generated content on the web. User-initiated community conversations provide as much as 30 times the number of official help desk solutions for consortium members! The growing reliance on user community solutions is clearly a user experience issue. Anne says that user assistance as conversation "means getting closer to users and helping them perform well. User-centered design has been touted as one of the most important ideas developed in the last 20 years of workplace writing. Now writers can take the idea of user-centered design a step further by starting conversations with users and enabling user assistance in interactions." Some of Anne's favorite examples of this paradigm shift from the world of traditional documentation to community conversation include: Writer Bob Bringhurst's blog about Adobe InDesign and InCopy products and Adobe's community help The Microsoft Development Network Community Center ·The former Sun (now Oracle) OpenDS wiki, NetBeans Ruby and other community approaches to engage diverse audiences using screencasts, wikis, and blogs. Cisco's customer support wiki, EMC's community, as well as Symantec and Intuit's approaches The efforts of Ubuntu, Mozilla, and the FLOSS community generally Adobe Writer Bob Bringhurst's Blog Oracle is not without a user community conversation too. Besides the community discussions and blogs around documentation offerings, we have the My Oracle Support Community forums, Oracle Technology Network (OTN) communities, wiki, blogs, and so on. We have the great work done by our user groups and customer councils. Employees like David Haimes reach out, and enthusiastic non-employee gurus like Chet Justice (OracleNerd), Floyd Teter and Eddie Awad provide great "how-to" information too. But what does this paradigm shift mean for existing technical writers as users turn away from the traditional printable PDF manual deliverables? We asked Anne after the conference. The writer role becomes one of conversation initiator or enabler. The role evolves, along with the process, as the users define their concept of user assistance and terms of engagement with the product instead of having it pre-determined. It is largely a case now of "inventing the job while you're doing it, instead of being hired for it" Anne said. There is less emphasis on formal titles. Anne mentions that her own title "Content Stacker" at OpenStack; others use titles such as "Content Curator" or "Community Lead". However, the role remains one essentially about communications, "but of a new type--interacting with users, moderating, curating content, instead of sitting down to write a manual from start to finish." Clearly then, this role is open to more than professional technical writers. Product managers who write blogs, developers who moderate forums, support professionals who update wikis, rock star programmers with a penchant for YouTube are ideal. Anyone with the product knowledge, empathy for the user, and flair for relationships on the social web can join in. Some even perform these roles already but do not realize it. Anne feels the technical communicator space will move from hiring new community conversation professionals (who are already active in the space through blogging, tweets, wikis, and so on) to retraining some existing writers over time. Our own research reveals that the established proponents of community user assistance even set employee performance objectives for internal content curators about the amount of community content delivered by people outside the organization! To take advantage of the conversations on the web as user assistance, enterprises must first establish where on the spectrum their community lies. "What is the line between community willingness to contribute and the enterprise objectives?" Anne asked. "The relationship with users must be managed and also measured." Anne believes that the process can start with a "just do it" approach. Begin by reaching out to existing user groups, individual bloggers and tweeters, forum posters, early adopter program participants, conference attendees, customer advisory board members, and so on. Use analytical tools to measure the level of conversation about your products and services to show a return on investment (ROI), winning management support. Anne emphasized that success with the community model is dependent on lowering the technical and motivational barriers so that users can readily contribute to the conversation. Simple tools must be provided, and guidelines, if any, must be straightforward but not mandatory. The conversational approach is one where traditional style and branding guides do not necessarily apply. Tools and infrastructure help users to create content easily, to search and find the information online, read it, rate it, translate it, and participate further in the content's evolution. Recognizing contributors by using ratings on forums, giving out Twitter kudos, conference invitations, visits to headquarters, free products, preview releases, and so on, also encourages the adoption of the conversation model. The move to conversation as user assistance is not free, but there is a business ROI. The conversational model means that customer service is enhanced, as user experience moves from a functional to a valued, emotional level. Studies show a positive correlation between loyalty and financial performance (Consortium for Service Innovation, 2010), and as customer experience and loyalty become key differentiators, user experience professionals cannot explore the model's possibilities. The digital universe (measured at 1.2 million petabytes in 2010) is doubling every 12 to 18 months, and 70 percent of that universe consists of user-generated content (IDC, 2010). Conversation as user assistance cannot be ignored but must be embraced. It is a time to manage for abundance, not scarcity. Besides, the conversation approach certainly sounds more interesting, rewarding, and fun than the traditional model! I would like to thank Anne for her time and thoughts, and recommend that all user assistance professionals read her book. You can follow Anne on Twitter at: http://www.twitter.com/annegentle.

  • Fixing up Visual Studio&rsquo;s gitignore , using IFix

    - by terje
    Originally posted on: http://geekswithblogs.net/terje/archive/2014/06/13/fixing-up-visual-studiorsquos-gitignore--using-ifix.aspxDownload tool Is there anything wrong with the built-in Visual Studio gitignore ???? Yes, there is !  First, some background: When you set up a git repo, it should be small and not contain anything not really needed.  One thing you should not have in your git repo is binary files. These binary files may come from two sources, one is the output files, in the bin and obj folders.  If you have a  gitignore file present, which you should always have (!!), these folders are excluded by the standard included file (the one included when you choose Team Explorer/Settings/GitIgnore – Add.) The other source are the packages folder coming from your NuGet setup.  You do use NuGet, right ?  Of course you do !  But, that gitignore file doesn’t have any exclude clause for those folders.  You have to add that manually.  (It will very probably be included in some upcoming update or release).  This is one thing that is missing from the built-in gitignore. To add those few lines is a no-brainer, you just include this: # NuGet Packages packages/* *.nupkg # Enable "build/" folder in the NuGet Packages folder since # NuGet packages use it for MSBuild targets. # This line needs to be after the ignore of the build folder # (and the packages folder if the line above has been uncommented) !packages/build/ Now, if you are like me, and you probably are, you add git repo’s faster than you can code, and you end up with a bunch of repo’s, and then start to wonder: Did I fix up those gitignore files, or did I forget it? The next thing you learn, for example by reading this blog post, is that the “standard” latest Visual Studio gitignore file exist at https://github.com/github/gitignore, and you locate it under the file name VisualStudio.gitignore.  Here you will find all the new stuff, for example, the exclusion of the roslyn ide folders was commited on May 24th.  So, you think, all is well, Visual Studio will use this file …..     I am very sorry, it won’t. Visual Studio comes with a gitignore file that is baked into the release, and that is by this time “very old”.  The one at github is the latest.  The included gitignore miss the exclusion of the nuget packages folder, it also miss a lot of new stuff, like the Roslyn stuff. So, how do you fix this ?  … note .. while we wait for the next version… You can manually update it for every single repo you create, which works, but it does get boring after a few times, doesn’t it ? IFix Enter IFix ,  install it from here. IFix is a command line utility (and the installer adds it to the system path, you might need to reboot), and one of the commands is gitignore If you run it from a directory, it will check and optionally fix all gitignores in all git repo’s in that folder or below.  So, start up by running it from your C:/<user>/source/repos folder. To run it in check mode – which will not change anything, just do a check: IFix  gitignore --check What it will do is to check if the gitignore file is present, and if it is, check if the packages folder has been excluded.  If you want to see those that are ok, add the --verbose command too.  The result may look like this: Fixing missing packages Let us fix a single repo by adding the missing packages structure,  using IFix --fix We first check, then fix, then check again to verify that the gitignore is correct, and that the “packages/” part has been added. If we open up the .gitignore, we see that the block shown below has been added to the end of the .gitignore file.   Comparing and fixing with latest standard Visual Studio gitignore (from github) Now, this tells you if you miss the nuget packages folder, but what about the latest gitignore from github ? You can check for this too, just add the option –merge (why this is named so will be clear later down) So, IFix gitignore --check –merge The result may come out like this  (sorry no colors, not got that far yet here): As you can see, one repo has the latest gitignore (test1), the others are missing either 57 or 150 lines.  IFix has three ways to fix this: --add --merge --replace The options work as follows: Add:  Used to add standard gitignore in the cases where a .gitignore file is missing, and only that, that means it won’t touch other existing gitignores. Merge: Used to merge in the missing lines from the standard into the gitignore file.  If gitignore file is missing, the whole standard will be added. Replace: Used to force a complete replacement of the existing gitignore with the standard one. The Add and Replace options can be used without Fix, which means they will actually do the action. If you combine with --check it will otherwise not touch any files, just do a verification.  So a Merge Check will  tell you if there is any difference between the local gitignore and the standard gitignore, a Compare in effect. When you do a Fix Merge it will combine the local gitignore with the standard, and add what is missing to the end of the local gitignore. It may mean some things may be doubled up if they are spelled a bit differently.  You might also see some extra comments added, but they do no harm. Init new repo with standard gitignore One cool thing is that with a new repo, or a repo that is missing its gitignore, you can grab the latest standard just by using either the Add or the Replace command, both will in effect do the same in this case. So, IFix gitignore --add will add it in, as in the complete example below, where we set up a new git repo and add in the latest standard gitignore: Notes The project is open sourced at github, and you can also report issues there.

  • SQL Developer Blitz at ODTUG Kscope12

    - by thatjeffsmith
    Oracle Development Tools User Group (ODTUG) puts on an outstanding event, and I enjoy that the content comes FIRST. Yes, the after-event parties and entertainment are first class, but I look forward most to sitting in on some excellent sessions. For Kscope12 one would expect Oracle to have a large presence, and you would be absolutely correct! The APEX team will be there in full force, and we’ll have sessions on JDeveloper, ADF, and .NET. But what I want to talk about today is our awesome line-up of coverage for Oracle SQL Developer (Surprise!) DB and Developer’s Toolbox Symposium Kris Rice or @krisrice, Product Development Manager for SQL Developer, will speak at 10AM Sunday about SQL Developer Data Modeler. Our free data modeling solution allows one to reverse engineer a data dictionary to a model, modify it, and create a script of the changes. Collaboration is an important part of any development team; with built-in subversion support, the modeler makes collaboration easy, not just possible. After the morning break, I’ll be talking about SQL Developer’s PL/SQL support. From creating your code, to debugging, tuning, testing, and documenting PL/SQL – SQL Developer fits the bill. Since I have a full hour, I should have time to do a little riff on using source control to version and manage your revisions too! At 3:15 Jagan Athreya will talk about the new integration between SQL Developer and Enterprise Manager Cloud Control 12c. Enabling developers to define changes in SQLDeveloper and allowing DBAs to promote these changes to Test and Production via Enterprise Manager will reduce errors, accelerate productivity, and help eliminate unplanned downtime. Get your SQL Developer groove on at ODTUG Kscope12! Presentations SQL Developer Tips and Tricks Monday June 25, Session 5, 4:15 pm – 5:15 pm I’ll take you through my favorite keyboard shortcuts, top 10 preferences every user should tweak, and spotlight features that the average user probably hasn’t discovered yet. My goal for this session is for everyone to take 1-2 tips they can implement immediately to save mucho time. I enjoy interacting with the audience so no two versions of this presentation are the same. Oracle SQL Developer and Data Modeler New Features When: Tuesday June 26, Session 6, 8:30 am – 9:30 am Ashley Chen, my PM-partner-in-crime, will be covering all the new features from our two latest updates. So if you’re new to SQL Developer, or you’ve been using an older version, stop by and see what new toys you have to play with. I also have a bet with Ashley that she will have more attendees than me, so be sure to show up so I can collect. Debugging PL/SQL With SQL Developer When: Wednesday June 27, Session 16, 3:00 pm – 4:00 pm Me again – sorry. This time I have an entire hour to JUST talk about PL/SQL and debugging! Should you use a watch with a break condition, or a breakpoint with a passcount? How does external debugging with a Perl script work? Can I just debug an anonymous PL/SQL block. So if debugging to you is just a DBMS_OUTPUT.PUT_LINE() call, stop by and see how our IDE can help you take things to the next level! Or is that level++? Hands-on-Training SQL Developer Soup to Nuts When: Tuesday, 8:00 AM – 9:30 AM If you learn by doing, this is the session for you. Bring your own laptop or use one of the lab machines. We’ll give you a VirtualBox OEL image running 11gR2 EE Database with all the fixin’s (that’s Southern speak for Partitioning, Advanced Compression, Tuning & Diagnostic Packs, etc), TimesTen, APEX and much more. All you have to do is login and run through our lab exercises. You can start with a model and work your way up to debugging and testing your own appliction, or you can pick and choose your lessons to suit your needs. We’ll have people on hand to help you out and answer your questions. Booth Hours We’ll be in the vendor area and have our very own ‘demo pod’ for SQL Developer. Between Kris, Ashley, and I we should be able to answer your questions or show you how to ‘do that thing’ in the tool. Or just stop by and say hello! We’ll be around the following hours’ish: Sunday, June 24, 2012 6:00 PM – 8:00 PM Monday, June 25, 2012 9:00 AM – 4:30 PM Tuesday, June 26, 2012 9:30 AM – 3:30 PM Wednesday, June 27, 2012 10:15 AM – 2:00 PM No Excuses – If You Have Questions, This is Your Chance to Get Your Answers! We’re doing just about everything outside of a scavenger hunt to bring information and value to our users. Let us know what you like, what you don’t like, and we’ll do our best to do more of the former and less of the latter!

  • How to Troubleshoot TFS Build Server Failure?

    - by Tarun Arora
    Ever found your self in this helpless situation where you think you have tried every possible suggestion on the internet to bring the build server back but it just won’t work. Well some times before hunting around for a solution it is important to understand what the problem is, if the error messages in the build logs don’t seem to help you can always enable tracing on the build server to get more information on what could possibly be the root cause of failure. In this blog post today I’ll be showing you how to enable tracing on, - TFS 2010/11 Server - Build Server - Client Enable Tracing on Team Foundation Server 2010/2011 On the Team Foundation Server navigate to C:\Program Files\Microsoft Team Foundation Server 2010\Application Tier\Web Services, right click web.config and from the context menu select edit.          Search for the <appSettings> node in the config file and set the value of the key ‘traceWriter’ to true.          In the <System.diagnostics> tag set the value of switches from 0 to 4 to set the trace level to maximum to write diagnostics level trace information.          Restart the TFS Application pool to force this change to take effect. The application pool restart will impact any one using the TFS server at present. Note - It is recommended that you do not make any changes to the TFS production application server, this can have serious consequences and can even jeopardize the installation of your server.          Download the Debug view tool from http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx and set it to capture “Global Events”. Perform any actions in the Team Explorer on the client machine, you should be able to see a series of trace data in the debug view tool now.         Enable Tracing on Build Controller/Agents Log on to the Build Controller/Agent and Navigate to the directory C:\Program Files\Microsoft Team Foundation Server 2010\Tools         Look for the configuration file ‘TFSBuildServiceHost.exe.config’ if it is not already there create a new text file and rename it to ‘TFSBuildServiceHost.exe.config’         To Enable tracing uncomment the <system.diagnostics> and paste the snippet below if it is not already there. <configuration> <system.diagnostics> <switches> <add name="BuildServiceTraceLevel" value="4"/> </switches> <trace autoflush="true" indentsize="4"> <listeners> <add name="myListener" type="Microsoft.TeamFoundation.TeamFoundationTextWriterTraceListener, Microsoft.TeamFoundation.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" initializeData="c:\logs\TFSBuildServiceHost.exe.log" /> <remove name="Default" /> </listeners> </trace> </system.diagnostics> </configuration> The highlighted path above is where the Log file will be created. If the folder is not already there then create the folder, also, make sure that the account running the build service has access to write to this folder.         Restart the build Controller/Agent service from the administration console (or net stop tfsbuildservicehost & net start tfsbuildservicehost) in order for the new setting to be picked up.         Enable TFS Tracing on the Client Machine On the client machine, shut down Visual Studio, navigate to C:\Program Files\Microsoft Visual Studio 10.0\Common 7\IDE          Search for devenv.exe.config, make a backup copy of the config file and right click the file and from the context menu select edit. If its not already there create this file.          Edit devenv.exe.config by adding the below code snippet before the last </configuration> tag <system.diagnostics> <switches> <add name="TeamFoundationSoapProxy" value="4" /> <add name="VersionControl" value="4" /> </switches> <trace autoflush="true" indentsize="3"> <listeners> <add name="myListener" type="Microsoft.TeamFoundation.TeamFoundationTextWriterTraceListener,Microsoft.TeamFoundation.Common, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" initializeData="c:\tf.log" /> <add name="perfListener" type="Microsoft.TeamFoundation.Client.PerfTraceListener, Microsoft.TeamFoundation.Client, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> </listeners> </trace> </system.diagnostics> The highlighted path above is where the Log file will be created. If the folder is not already there then create the folder. Start Visual Studio and after a bit of activity you should be able to see the new log file being created on the folder specified in the config file. Other Resources Below are some Key resource you might like to review. I would highly recommend the documentation, walkthroughs and videos available on MSDN.   Thank you for taking the time out and reading this blog post.

However, the role remains one essentially about communications, "but of a new type--interacting with users, moderating, curating content, instead of sitting down to write a manual from start to finish." Clearly then, this role is open to more than professional technical writers. Product managers who write blogs, developers who moderate forums, support professionals who update wikis, rock star programmers with a penchant for YouTube are ideal. Anyone with the product knowledge, empathy for the user, and flair for relationships on the social web can join in. Some even perform these roles already but do not realize it. Anne feels the technical communicator space will move from hiring new community conversation professionals (who are already active in the space through blogging, tweets, wikis, and so on) to retraining some existing writers over time. Our own research reveals that the established proponents of community user assistance even set employee performance objectives for internal content curators about the amount of community content delivered by people outside the organization! To take advantage of the conversations on the web as user assistance, enterprises must first establish where on the spectrum their community lies. "What is the line between community willingness to contribute and the enterprise objectives?" Anne asked. "The relationship with users must be managed and also measured." Anne believes that the process can start with a "just do it" approach. Begin by reaching out to existing user groups, individual bloggers and tweeters, forum posters, early adopter program participants, conference attendees, customer advisory board members, and so on. Use analytical tools to measure the level of conversation about your products and services to show a return on investment (ROI), winning management support. Anne emphasized that success with the community model is dependent on lowering the technical and motivational barriers so that users can readily contribute to the conversation. Simple tools must be provided, and guidelines, if any, must be straightforward but not mandatory. The conversational approach is one where traditional style and branding guides do not necessarily apply. Tools and infrastructure help users to create content easily, to search and find the information online, read it, rate it, translate it, and participate further in the content's evolution. Recognizing contributors by using ratings on forums, giving out Twitter kudos, conference invitations, visits to headquarters, free products, preview releases, and so on, also encourages the adoption of the conversation model. The move to conversation as user assistance is not free, but there is a business ROI. The conversational model means that customer service is enhanced, as user experience moves from a functional to a valued, emotional level. Studies show a positive correlation between loyalty and financial performance (Consortium for Service Innovation, 2010), and as customer experience and loyalty become key differentiators, user experience professionals cannot explore the model's possibilities. The digital universe (measured at 1.2 million petabytes in 2010) is doubling every 12 to 18 months, and 70 percent of that universe consists of user-generated content (IDC, 2010). Conversation as user assistance cannot be ignored but must be embraced. It is a time to manage for abundance, not scarcity. Besides, the conversation approach certainly sounds more interesting, rewarding, and fun than the traditional model! I would like to thank Anne for her time and thoughts, and recommend that all user assistance professionals read her book. You can follow Anne on Twitter at: http://www.twitter.com/annegentle.

  • SQL – Quick Start with Explorer Sections of NuoDB – Query NuoDB Database

    - by Pinal Dave
    This is the third post in the series of the blog posts I am writing about NuoDB. NuoDB is very innovative and easy-to-use product. I can clearly see how one can scale-out NuoDB with so much ease and confidence. In my very first blog post we discussed how we can install NuoDB (link), and in my second post I discussed how we can manage the NuoDB database transaction engines and storage managers with a few clicks (link). Note: You can Download NuoDB from here. In this post, we will learn how we can use the Explorer feature of NuoDB to do various SQL operations. NuoDB has a browser-based Explorer, which is very powerful and has many of the features any IDE would normally have. Let us see how it works in the following step-by-step tutorial. Let us go to the NuoDBNuoDB Console by typing the following URL in your browser: http://localhost:8080/ It will bring you to the QuickStart screen. Make sure that you have created the sample database. If you have not created sample database, click on Create Database and create it successfully. Now go to the NuoDB Explorer by clicking on the main tab, and it will ask you for your domain username and password. Enter the username as a domain and password as a bird. Alternatively you can also enter username as a quickstart and password as a quickstart. Once you enter the password you will be able to see the databases. In our example we have installed the Sample Database hence you will see the Test database in our Database Hierarchy screen. When you click on database it will ask for the database login. Note that Database Login is different from Domain login and you will have to enter your database login over here. In our case the database username is dba and password is goalie. Once you enter a valid username and password it will display your database. Further expand your database and you will notice various objects in your database. Once you explore various objects, select any database and click on Open. When you click on execute, it will display the SQL script to select the data from the table. The autogenerated script displays entire result set from the database. The NuoDB Explorer is very powerful and makes the life of developers very easy. If you click on List SQL Statements it will list all the available SQL statements right away in Query Editor. You can see the popup window in following image. Here is the cool thing for geeks. You can even click on Query Plan and it will display the text based query plan as well. In case of a SELECT, the query plan will be much simpler, however, when we write complex queries it will be very interesting. We can use the query plan tab for performance tuning of the database. Here is another feature, when we click on List Tables in NuoDB Explorer.  It lists all the available tables in the query editor. This is very helpful when we are writing a long complex query. Here is a relatively complex example I have built using Inner Join syntax. Right below I have displayed the Query Plan. The query plan displays all the little details related to the query. Well, we just wrote multi-table query and executed it against the NuoDB database. You can use the NuoDB Admin section and do various analyses of the query and its performance. NuoDB is a distributed database built on a patented emergent architecture with full support for SQL and ACID guarantees.  It allows you to add Transaction Engine processes to a running system to improve the performance of your system.  You can also add a second Storage Engine to your running system for redundancy purposes.  Conversely, you can shut down processes when you don’t need the extra database resources. NuoDB also provides developers and administrators with a single intuitive interface for centrally monitoring deployments. If you have read my blog posts and have not tried out NuoDB, I strongly suggest that you download it today and catch up with the learnings with me. Trust me though the product is very powerful, it is extremely easy to learn and use.

  • FAT Volume and CE

    - by Kate Moss' Open Space
    Whenever we format a disk volume, it is a good idea to name the label so it will be easier to categorize. To label a volume, we can use LABEL command or UI depends on your preference. Windows CE does provide FAT driver and support various format (FAT12, FAT16,FAT32, ExFAT and TFAT - transaction-safe FAT) and many feature to let you scan and even defrag the volume but not labeling. At any time you format a volume in CE and then mount it on PC, the label is always empty! Of course, you can always label the volume on PC, even it is formatted in CE. So looks like CE does not care about the volume label at all, neither report the label to OS nor changing the label on FAT.So how can we set the volume label in CE? To Answer this question, we need to know how does FAT stores the volume label. Here are some on-line resources are handy for parsing FAT. http://en.wikipedia.org/wiki/File_Allocation_Table http://www.pjrc.com/tech/8051/ide/fat32.html http://www.microsoft.com/whdc/system/platform/firmware/fatgen.mspx You can refer to PUBLIC\COMMON\OAK\DRIVERS\FSD\FATUTIL\MAIN\bootsec.h and dosbpb.h or the above links for the fields we discuss here. The first sector of a FAT Volume (it is not necessary to be the first sector of a disk.) is a FAT boot sector and BPB (BIOS Parameter Block). And at offset 43, bgbsVolumeLabel (or bsVolumeLabel on FAT16) is for storing the volume lable, but note in the spec also indicates "FAT file system drivers should make sure that they update this field when the volume label file in the root directory has its name changed or created.". So we can't just simply update the bgbsVolumeLabel but also need to create a volume lable file in root directory. The volume lable file is not a real file but just a file entry in root directory with zero file lenth and a very special file attribute, ATTR_VOLUME_ID. (defined in public\common\oak\drivers\fsd\fatutil\MAIN\fatutilp.h) Locating and accessing bootsector is quite straight forward, as long as we know the starting sector of a FAT volume, that's it. But where is the root directory? The layout of a typical FAT is like this Boot sector (Volume ID in the figure) followed by Reserved Sectors (1 on FAT12/16 and 32 on FAT32), then FAT chain table(s) (can be 1 or 2), after that is the root directory (FAT12/16 and not shows in the figure) then begining of the File and Directories. In FAT12/16, the root directory is placed right after FAT so it is not hard to caculate the offset in the volume. But in FAT32, this rule is no longer true: the first cluster of the root directory is determined by BGBPB_RootDirStrtClus (or offset 44 in boot sector). Although this field is usually 0x00000002 (it is how CE initial the root directory after formating a volume. Note we should never assume it is always true) which means the first cluster contains data but not like the root directory is contiguous in FAT12/16, it is just like a regular file can be fragmented. So we need to access the root directory (of FAT32) hopping one cluster to another by traversing FAT table. Let's trace the code now. Although the source of FAT driver is not available in CE Shared Source program, but the formatter, Fatutil.dll, is available in public\common\oak\drivers\fsd\fatutil\MAIN\formatdisk.cpp. Be aware the public code only provides formatter for FAT12/16/32 for ExFAT it is still not available. FormatVolumeInternal is the main worker function. With the knowledge here, you should be able the trace the code easily. But I would like to discuss the following code pieces     dwReservedSectors = (fo.dwFatVersion == 32) ? 32 : 1;     dwRootEntries = (fo.dwFatVersion == 32) ? 0 : fo.dwRootEntries; Note the dwReservedSectors is 32 in FAT32 and 1 in FAT12/16. Root Entries is another different mentioned in previous paragraph, 0 for FAT32 (dynamic allocated) and fixed size (usually 512, defined in DEFAULT_ROOT_ENTRIES in public\common\sdk\inc\fatutil.h) And then here   memset(pBootSec->bsVolumeLabel, 0x20, sizeof(pBootSec->bsVolumeLabel)); It sets the Volume Label as empty string. Now let's carry on to the next section - write the root directory.     if (fo.dwFatVersion == 32) {         if (!(fo.dwFlags & FATUTIL_FORMAT_TFAT)) {             dwRootSectors = dwSectorsPerCluster;         }         else {             DIRENTRY    dirEntry;             DWORD       offset;             int               iVolumeNo;             memset(pbBlock, 0, pdi->di_bytes_per_sect);             memset(&dirEntry, 0, sizeof(DIRENTRY));                         dirEntry.de_attr = ATTR_VOLUME_ID;             // the first one is volume label             memcpy(dirEntry.de_name, "TFAT       ", sizeof (dirEntry.de_name));             memcpy(pbBlock, &dirEntry, sizeof(dirEntry));              ...             // Skip the next step of zeroing out clusters             dwCurrentSec += dwSectorsPerCluster;             dwRootSectors = 0;         }     }     // Each new root directory sector needs to be zeroed.     memset(pbBlock, 0, cbSizeBlk);     iRootSec=0;     while ( iRootSec < dwRootSectors) { Basically, the code zero out the each entry in root directory depends on dwRootSectors. In FAT12/16, the dwRootSectors is calculated as the sectors we need for the root entries (512 for most of the case) and in FAT32 it just zero out the one cluster. Please note that, if it is a TFAT volume, it initialize the root directory with special volume label entries for some special purpose. Despite to its unusual initialization process for TFAT, it does provide a example for how to create a volume entry. With some minor modification, we can assign the volume label in FAT formatter and also remember to sync the volume label with bsVolumeLabel or bgbsVolumeLabel in boot sector.

  • JMaghreb 2012 Trip Report

    - by arungupta
    JMaghreb is the inaugural Java conference organized by Morocco JUG. It is the biggest Java conference in Maghreb (5 countries in North West Africa). Oracle was the exclusive platinum sponsor with several others. The registrations had to be closed at 1412 for the free conference and several folks were already on the waiting list. Rabat with 531 registrations and Casablanca with 426 were the top cities. Some statistics ... 850+ attendees over 2 days, 500+ every day 30 sessions were delivered by 18 speakers from 10 different countries 10 sessions in French and 20 in English 6 of the speakers spoke at JavaOne 2012 8 will be at Devoxx Attendees from 5 different countries and 57 cities in Morocco 40.9% qualified them as professional and rest as students Topics ranged from HTML5, Java EE 7, ADF, JavaFX, MySQL, JCP, Vaadin, Android, Community, JCP Java EE 6 hands-on lab was sold out within 7 minutes and JavaFX in 12 minutes I gave the keynote along with Simon Ritter which was basically a recap of the Strategy and Technical keynotes presented at JavaOne 2012. An informal survey during the keynote showed the following numbers: 25% using NetBeans, 90% on Eclipse, 3 on JDeveloper, 1 on IntelliJ About 10 subscribers to free online Java magazine. This digital magazine is a comprehensive source of information for everything Java - subscribe for free!! About 10-15% using Java SE 7. Download JDK 7 and get started today! Even JDK 8 builds have been available for a while now. My second talk explained the core concepts of WebSocket and how JSR 356 is providing a standard API to build WebSocket-driven applications in Java EE 7. TOTD #183 explains how you can easily get started with WebSocket in GlassFish 4. The complete slide deck is available: Next day started with a community keynote by Sonya Barry. Some of us live the life of JCP, JSR, EG, EC, RI, etc every day, but not every body is. To address that, Sonya prepared an excellent introductory presentation providing an explanation of these terms and how java.net infrastructure supports Java development. The registration for the lab showed there is a definite demand for these technologies in this part of the world. I delivered the Java EE 6 hands-on lab to a packed room of about 120 attendees. Most of the attendees were able to progress and follow the lab instructions. Some of the attendees did not have a laptop but were taking extensive notes on paper notepads. Several attendees were already using Java EE 6 in their projects and typically they are the ones asking deep dive questions. Also gave out three copies of my recently released Java EE 6 Pocket Guide and new GlassFish t-shirts. Definitely feels happy to coach ~120 more Java developers learn standards-based enterprise Java programming. I also participated in a JCP BoF along with Werner, Sonya, and Badr. Adotp-a-JSR, java.net infrastructure, how to file a JSR, what is an RI, and other similar topics were discussed in a candid manner. You can follow @JMaghrebConf or check out their facebook page. java.net published a timely conversation with Badr El Houari - the fearless leader of the Morocco JUG team. Did you know that Morocco JUG stood for JCP EC elections (ADD LINK) ? Even though they did not get elected but did fairly well. Now some sample tweets from #JMaghreb ... #JMaghreb is over. Impressive for a first edition! Thanks @badrelhouari and all the @MoroccoJUG team ! Since you @speakjava : System.out.println("Thank you so much dear Tech Evangelist ! The JavaFX was pretty amazing !!!

The Glassdoor guy #arungupta is doing it RIGHT ! #JMaghreb Great presentation of The Future of the Java Platform: Java EE 7, Java SE 8 & Beyond #jMaghreb @arungupta is a great Guy apparently #JMaghreb On a personal front, the hotel (Soiftel Jardin des Roses) was pretty nice and the location was perfect. There was a 1.8 mile loop dirt trail right next to it so I managed to squeeze some runs before my upcoming marathon. Also enjoyed some great Moroccan cuisine - Couscous, Tajine, mint tea, and moroccan salad. Visit to Kasbah of the Udayas, Hassan II (one of the tallest mosque in the world), and eating in a restaurant in a kasbah are some of the exciting local experiences. Now some pictures from the event (and around the city) ... And the complete album: Many thanks to Badr, Faisal, and rest of the team for organizing a great conference. They are already thinking about how to improve the content, logisitics, and flow for the next year. I'm certainly looking forward to JMaghreb 2.0 :-)

  • Weekend reading: Microsoft/Oracle and SkyDrive based code-editor

    - by jamiet
    A couple of news item caught my eye this weekend that I think are worthy of comment. Microsoft/Oracle partnership to be announced tomorrow (24/06/2013) According to many news site Microsoft and Oracle are about to announce a partnership (Oracle set for major Microsoft, Salesforce, Netsuite partnerships) and they all seem to be assuming that it will be something to do with “the cloud”. I wouldn’t disagree with that assessment, Microsoft are heavily pushing Azure and Oracle seem (to me anyway) to be rather lagging behind in the cloud game. More specifically folks seem to be assuming that Oracle’s forthcoming 12c database release will be offered on Azure. I did a bit of reading about Oracle 12c and one of its key pillars appears to be that it supports multi-tenant topologies and multi-tenancy is a common usage scenario for databases in the cloud. I’m left wondering then, if Microsoft are willing to push a rival’s multi-tenant solution what is happening to its own cloud-based multi-tenant offering – SQL Azure Federations. We haven’t heard anything about federations for what now seems to be a long time and moreover the main Program Manager behind the technology, Cihan Biyikoglu, recently left Microsoft to join Twitter. Furthermore, a Principle Architect for SQL Server, Conor Cunningham, recently presented the opening keynote at SQLBits 11 where he talked about multi-tenant solutions on SQL Azure and not once did he mention federations. All in all I don’t have a warm fuzzy feeling about the future of SQL Azure Federations so I hope that that question gets asked at some point following the Microsoft/Oracle announcement. Text Editor on SkyDrive with coding-specific features Liveside.net got a bit of a scoop this weekend with the news (Exclusive: SkyDrive.com to get web-based text file editing features) that Microsoft’s consumer-facing file storage service is going to get a new feature – a web-based code editor. Here’s Liveside’s screenshot: I’ve long had a passing interest in online code editors, indeed back in December 2009 I wondered out loud on this blog site: I started to wonder when the development tools that we use would also become cloud-based. After all, if we’re using cloud-based services does it not make sense to have cloud-based tools that work with them? I think it does. Project Houston Since then the world has moved on. Cloud 9 IDE (https://c9.io/) have blazed a trail in the fledgling world of online code editors and I have been wondering when Microsoft were going to start playing catch-up. I had no doubt that an online code editor was in Microsoft’s future; its an obvious future direction, why would I want to have to download and install a bloated text editor (which, arguably, is exactly what Visual Studio amounts to) and have to continually update it when I can simply open a web browser and have ready access to all of my code from wherever I am. There are signs that Microsoft is already making moves in this direction, after all the URL for their new offering Team Foundation Service doesn’t mention TFS at all – my own personalised URL for Team Foundation Service is http://jamiet.visualstudio.com – using “Visual Studio” as the domain name for a service that isn’t strictly speaking part of Visual Studio leads me to think that there’s a much bigger play here and that one day http://visualstudio.com will house an online code editor. With that in mind then I find Liveside’s revelation rather intriguing, why would a code editing tool show up in Skydrive? Perhaps SkyDrive is going to get integrated more tightly into TFS, I’m very interested to see where this goes. The larger question playing on my mind though is whether an online code editor from Microsoft will support SQL Server developers. I have opined before (see The SQL developer gap) about the shoddy treatment that SQL Server developers have to experience from Microsoft and I haven’t seen any change in Microsoft’s attitude in the three and a half years since I wrote that post. I’m constantly bewildered by the lack of investment in SQL Server developer productivity compared to the riches that are lavished upon our appdev brethren. When you consider that SQL Server is Microsoft’s third biggest revenue stream it is, frankly, rather insulting. SSDT was a step in the right direction but the hushed noises I hear coming out of Microsoft of late in regard to SSDT don’t bode fantastically well for its future. So, will an online code editor from Microsoft support T-SQL development? I have to assume not given the paucity of investment on us lowly SQL Server developers over the last few years, but I live in hope! Your thoughts in the comments section please. I would be very interested in reading them. @Jamiet

To install: Download and install SOA 11.1.1.2.0, which is a full release (you can find the bits at the above location) Download and install SOA 11.1.1.3.0 During configure step (using the Fusion Middleware configuration wizard), use the Oracle Business Process Management template supplied with the SOA Suite11g (11.1.1.3.0) If you plan to use Process Spaces, also install Web Center 11.1.1.3.0, which also is delivered as a sparse release and needs to be installed on top of Web Center 11.1.1.2.0 Some early feedback We have been receiving very encouraging feedback on this release. Some quotes from partners are included below: “I just attended a preview workshop on BPM Studio, Oracle's BPMN 2.0 tool, held by Clemens Utschig Utschig from Oracle HQ. The usability and ease to get started are impressive. In the business view analysts can intuitively start modeling, then developers refine in their own, more technical view. The BPM Studio sets itself apart from pure play BPMN 2.0 tools by being seamlessly integrated inside a holistic SOA / BPM toolset: BPMN models are placed in SCA-Composites in SOA Suite 11g. This allows to abstract away the complexities of SOA integration aspects from business process aspects. For UIs in BPMN tasks, you have the richness of ADF 11g based Frontends. With BPM Studio we architects have a new modeling and development IDE that gives us interesting design challenges to grasp and elaborate, since many things BPMN 2.0 are different from good ol' BPEL. For example, for simple transformations, you don't use BPEL "assign" any more, but add the transformation directly to the service call. There is much less XPath involved. And, there is no translation from model to BPEL code anymore, so the awkward process model to BPEL roundtrip, which never really worked as well as it looked on marketing slides, is obsolete: With BPMN 2.0 "the model is the code". Now, these are great times to start the journey into BPM! Some tips: Start Projects smoothly, with initial processes being not overly complex and not using the more esoteric areas of BPMN, to manage the learning path and to stay successful with each iteration. Verify non functional requirements by conducting performance and load tests early. As mentioned above, separate all technical integration logic into SOA Suite or Oracle Service Bus. And - share your experience!” Hajo Normann, SOA Architect - Oracle ACE Director - Co-Leader DOAG SIG SOA   "Reuse of components across the Oracle 11G Fusion Middleware stack, like for instance a Database Adapter, is essential. It improves stability and predictability of the solution. BPM just is one of the components plugging into the stack and reuses all other components." Mr. Leon Smiers, Oracle Solution Architect, Capgemini   “I had the opportunity to follow a hands-on workshop held by Clemens for Oracle partners and I was really impressed of the overall offering of BPM11g. BPM11g allows the execution of BPMN 2.0 processes, without having to transform/translate them first to BPEL in order to be executable. The fact that BPMN uses the same underlying service infrastructure of SOA Suite 11g has a lot of benefits for us already familiar with SOA Suite 11g. BPMN is just another SCA component within a SCA composite and can (re)use all the existing components like Rules, Human Workflow, Adapters and Mediator. I also like the fact that BPMN runs on the same service engine as BPEL. By that all known best practices for making a BPEL  process reliable are valid for BPMN processes as well. Last but not least, BPMN is integrated into the superior end-to-end tracing of SOA Suite 11g. With BPM11g, Oracle offers a very competitive product which will have a big effect on the IT market. Clemens and Jürgen: Thanks for the great workshop! I’m really looking forward to my first project using Oracle BPM11g!” Guido Schmutz, Technology Manager / Oracle ACE Director for Fusion Middleware and SOA, Company:  Trivadis Some earlier feedback were summarized in this post.

  • F# for the C# Programmer

    - by mbcrump
    Are you a C# Programmer and can’t make it past a day without seeing or hearing someone mention F#?  Today, I’m going to walk you through your first F# application and give you a brief introduction to the language. Sit back this will only take about 20 minutes. Introduction Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution . In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it is now will now be shipped as one of the core languages in Visual Studio 2010 , alongside C++, C# 4.0 and VB. The F# programming language incorporates many state-of-the-art features from programming language research and ossifies them in an industrial strength implementation that promises to revolutionize interactive, parallel and concurrent programming. Advantages of F# F# is the world's first language to combine all of the following features: Type inference: types are inferred by the compiler and generic definitions are created automatically. Algebraic data types: a succinct way to represent trees. Pattern matching: a comprehensible and efficient way to dissect data structures. Active patterns: pattern matching over foreign data structures. Interactive sessions: as easy to use as Python and Mathematica. High performance JIT compilation to native code: as fast as C#. Rich data structures: lists and arrays built into the language with syntactic support. Functional programming: first-class functions and tail calls. Expressive static type system: finds bugs during compilation and provides machine-verified documentation. Sequence expressions: interrogate huge data sets efficiently. Asynchronous workflows: syntactic support for monadic style concurrent programming with cancellations. Industrial-strength IDE support: multithreaded debugging, and graphical throwback of inferred types and documentation. Commerce friendly design and a viable commercial market. Lets try a short program in C# then F# to understand the differences. Using C#: Create a variable and output the value to the console window: Sample Program. using System;   namespace ConsoleApplication9 {     class Program     {         static void Main(string[] args)         {             var a = 2;             Console.WriteLine(a);             Console.ReadLine();         }     } } A breeze right? 14 Lines of code. We could have condensed it a bit by removing the “using” statment and tossing the namespace. But this is the typical C# program. Using F#: Create a variable and output the value to the console window: To start, open Visual Studio 2010 or Visual Studio 2008. Note: If using VS2008, then please download the SDK first before getting started. If you are using VS2010 then you are already setup and ready to go. So, click File-> New Project –> Other Languages –> Visual F# –> Windows –> F# Application. You will get the screen below. Go ahead and enter a name and click OK. Now, you will notice that the Solution Explorer contains the following: Double click the Program.fs and enter the following information. Hit F5 and it should run successfully. Sample Program. open System let a = 2        Console.WriteLine a As Shown below: Hmm, what? F# did the same thing in 3 lines of code. Show me the interactive evaluation that I keep hearing about. The F# development environment for Visual Studio 2010 provides two different modes of execution for F# code: Batch compilation to a .NET executable or DLL. (This was accomplished above). Interactive evaluation. (Demo is below) The interactive session provides a > prompt, requires a double semicolon ;; identifier at the end of a code snippet to force evaluation, and returns the names (if any) and types of resulting definitions and values. To access the F# prompt, in VS2010 Goto View –> Other Window then F# Interactive. Once you have the interactive window type in the following expression: 2+3;; as shown in the screenshot below: I hope this guide helps you get started with the language, please check out the following books for further information. F# Books for further reading   Foundations of F# Author: Robert Pickering An introduction to functional programming with F#. Including many samples, this book walks through the features of the F# language and libraries, and covers many of the .NET Framework features which can be leveraged with F#.       Functional Programming for the Real World: With Examples in F# and C# Authors: Tomas Petricek and Jon Skeet An introduction to functional programming for existing C# developers written by Tomas Petricek and Jon Skeet. This book explains the core principles using both C# and F#, shows how to use functional ideas when designing .NET applications and presents practical examples such as design of domain specific language, development of multi-core applications and programming of reactive applications.
