  • An Interview with JavaOne Rock Star Martijn Verburg

    - by Janice J. Heiss
    An interview with JavaOne Rock Star Martijn Verburg, by yours truly, titled “Challenging the Diabolical Developer: A Conversation with JavaOne Rock Star Martijn Verburg,” is now up on otn/java. Verburg, one of the leading movers and shakers in the Java community, is well known for his ‘diabolical developer” talks at JavaOne where he uncovers some of the worst practices that Java developers are prone to. He mentions a few in the interview: * “A lack of communication: Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson.* No source control: Some developers simply store code in local file systems and e-mail the code in order to integrate their changes; yes, this still happens.* Design-driven design: Some developers are inclined to cram every design pattern from the Gang of Four (GoF) book into their projects. Of course, by that stage, they've actually forgotten why they're building the software in the first place.” He points to a couple of core assumptions and confusions that lead to trouble: “One is that developers think that the JVM is a magic box that will clean up their memory and make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try to force Java (the language) to do something it's not very good at, such as rapid Web development. So you get a proliferation of overly complex frameworks, libraries, and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!” Verburg has many insightful things to say about how to keep a Java User Group (JUG) going, about the “Adopt a JSR” program, bugathons, and much more.

  • How would you TDD the functionality of getting the corresponding process of a running windows service?

    - by Matt Spinelli
    Purpose Over the last year or more I've been learning unit testing via books I've read recently like The Art of Unit Testing, Working Effectively with Legacy Code, and others. I've also been using unit tests, mocking frameworks, and the like, periodically at work and definitely see the value. However, I'm still having a hard time wrapping my mind around TDD (as opposed to TAD) when the situation calls for code that is gong to mostly use external API calls. Problem to solve Get the process associated with a windows service using the service name. example: Function GetProcess(ByVal serviceName As String) As Process Rules Show each major iteration in production & test code using TDD No need to see any other code or configuration that is required to get things to run. Just curious about the interfaces, concrete classes, and test methods. C# or VB.NET Must use the .Net framework regarding services/processes (i.e. System.Diagnostics.Process) Test Frameworks: Nunit or MSTest Isolation Frameworks: Moq, Rhino Mock, or Microsoft Moles Must write true unit tests (no integration tests) Additional notes As far as I can tell there are two approaches design wise. Use an Inversion of Control approach along with using the Adapter and/or Facade patterns to wrap the underlying .net framework objects dealing with processes and services. Keep the .net framework code in the class containing the Get Process method and use code detouring (interception) via Microsoft Moles to isolate the hard dependencies from the method under test.

  • When are Bold/Italic Fonts Used in Windows?

    - by Otaku
    Environment: Windows 7, MS Office 2007, OpenOffice In the Control Panel-Fonts section, there are a number of fonts available, sometimes as families. For example, the Arial family (double click on it) shows both Arial and Arial Narrow. The Arial one has a few different versions, like "Arial Bold" and "Arial Bold Italic" and "Arial Italic". The Cambria font is the similar. When, if at all, are these Bold, Italic, etc. versions of these fonts ever used? In MS Office and OpenOffice they they are not available to choose from. Any insights on if I even need to keep them on my system at all?

    - by dagit
    This is happening on a Windows Vista machine with Office 2007 Ultimate. I have run repair from the control panel and also the MS Office Diagnostic tool. No problems are reported. When I started Outlook my mail box opens and I can read my messages. If I click compose or reply then Outlook gives me a dialog that says, "Not Implemented." The rest of office seems to be working fine. Does anyone know what causes this or the correct way to repair it? Thanks!

  • Usage of two Routers on LAN

    - by brusilva
    I've currently own a Linksys E4200 and a Thomson 546v6. Because I have an IPTV service I must set the Thomson as the main router connected to the phone line so that I can distribute the video signal for 2 specific ports and the other two for LAN Access. The problem is that the Thomson doesn't like port forwards, it usually doesnt work and since I have a good router (linksys) currently only working as Access Point I would like to use it as a router itself. I don't want to do a NAT beyond NAT so my question is should I connect the E4200 and to thomson and set the E4200 as a DMZ machine and then control all trafic on the E4200 itself or is there any other option that could suit my needs better?

  • Stop jucheck from running

    - by Ken
    I've installed Java on Windows Vista, and every day I get a Vista security warning asking me if I want to run "jucheck". Apparently this is the Java automatic updater. Well, I don't want it to run on its own, ever. I cancel it, and quit it. I right-click on the taskbar and unclick "Check for Updates Automatically", and then click "Never Check", and "Apply". And yet, it never remembers this setting. If I come back to the "Java Control Panel" right after clicking "OK", the very same box is checked again, all on its own. Is there some way to kill jucheck once and for all? If I simply delete jucheck.exe, will Java (other than the automatic check) still work, and will manual updates still work, and will it stop even trying to update every morning?

  • How do I get back hard drive space after I have uninstalled Ubuntu from Windows?

    - by Shantanu
    I installed Ubuntu on windows like it says to do it on Ubuntu's website as an application. I did not want it to create a separate partition on my hard drive. A few days ago, I uninstalled Ubuntu by going into the Windows control panel and hitting uninstall. As you would expect, I would get back my 100 or so gb on the disc. i never really installed anything of importance on ubuntu so i never had a second thought about uninstalling it. But I never got back my 100gb from Ubuntu. Now when I add up all of the folders on my c drive, they total to the amount I had on windows before I uninstalled Ubuntu but when I look at the My Computer screen, it says that another 100 or so gb is missing. I tried defragmenting the disc, downloading various disc managers but nothing fixed the space problem. Can anyone please help me with this!!??? Any help is much appreciated! Just making sure: UBUNTU WAS NOT ON A SEPARATE PARTITION, IT WAS INSTALLED AS AN APPLICATION ON WINDOWS. It tells yuo how to do this here except i did it with a much older version (i think it was 8.04 or soemthing): http://www.ubuntu.com/download/help/install-ubuntu-with-windows

  • Overwrite SOA expiry in a bind9 slave name server.

    - by Joachim Breitner
    I run a slave name server of a domain that I do not have full control over (i.e. changing the SOA is not possibly). The SOA specifies an expiry time of one week. For various reasons, I’d like to override that value on my specific slave server to something larger. Is there a way to do that? N.B: I know that for the refresh and retry fields, bind9 provides the options min-refresh-time, max-refresh-time, min-retry-time and max-retry-time to overrule the SOA, as mentioned in the documentation. For some reason this just does not inclucde expiry.

  • What is Mobsync.exe? Assuming I don't need it, can I disable it in Windows 7 without ill side effect

    - by Chris W. Rea
    I'm running Windows 7. Occasionally when I resume my computer from standby, it seems to wait 20-30 seconds or so before giving me full control back. In an attempt to diagnose why, I've been watching what's going on using the awesome Process Explorer. One of the processes I've noticed being started during that hiccup time is Mobsync.exe, described as "Microsoft Sync Center". Sync? Sync what? So, what is Mobsync.exe used for, exactly? Assuming I don't need its functionality, can I disable it in Windows 7 without ill side effect? If so, what's the best way to disable Mobsync.exe?

  • Explanation of various domain name records?

    - by Kumar
    At the time of hosting, normally we just change name servers in the domain control panel. It's fine if both mail and web servers are the same. When they're different, we need to change the DNS records. When I try to point my blog to my domain name, I came to know about the various types of DNS records - A Records, AAA Records, MX Records, CNAME Records, NS Records, TXT Records, SRV Records, SOA Records, etc. I searched on Google, but would like to know more about these deeply. I found this link on the Internet - http://www.directnic.com/help/faq/?question_id=103 and got some idea about the different DNS records. But I have some more questions. How do the domain name records work? Is there any difference between NS record and other records in the way they work? Where should the NS record point to when using A record, CNAME record and MX record?

  • Monitor sleep in Windows XP does not work. Is there an add on to force it?

    - by bert
    I have an EEE box with XP Home and a DVI connected TFT, and it does not sleep the monitor. It only starts working after I go to the energy control panel and turn it off and on again. Then the timed sleep works for the current session of computer use. After a shut down and boot next day, sleep does not work again (it is still set in the preferences however). What can hold the sleep function from working? Are there issues with Skype or MSN? Is there a utility to be less critic to processes interrupting sleep and offer a more reliable monitor sleep function for XP?

  • In search of database delivery practitioners and enthusiasts

    - by Claire Brooking
    We know from speaking with many of you at tradeshows and user groups that database delivery is not a factory production line. During planning, evaluation, quality control, and disaster mitigation, the people having their say at each step means that successful database deployment is a carefully managed course of action. With so many factors involved at every stage, we would love to find a way for our software to help out, by simplifying processes, speeding them up or joining together the people and the steps that make it all happen. We’re hoping our new research group for database delivery (SQL Server and Oracle) will help us understand the views and experiences of those of you out there in the trenches managing database changes. As part of our new group, we’ll be running a variety of research sessions, including surveys and phone interviews, over coming months. If you have opinions to share on Continuous Integration or Continuous Delivery for databases, we’d love to hear from you. Your feedback really will count as the product teams at Red Gate build plans. For some of our more in-depth sessions, we’ll also be offering participants an Amazon voucher as a thank-you for your time. If you’re not yet practising automated database deployment processes, but are contemplating or planning it, please do consider joining our research group too. If you’d like to sign up to the group and find out more, please fill in a quick form online, and we’ll be in touch to let you know about new research opportunities you might be interested in. We look forward to hearing your stories!

  • Dell 620 display is too bright to use

    - by keith
    I have a Dell D620 with a display problem. In windows 7 the display seems to be too bright, the text is broken up, the only way to see the mouse is at a very oblique angle. Changing the brightness with fn and brightness control has little/no effect. When I put it in high contrast mode I can see all the colors, but any windows pictures etc are still useless. I cannot get it to connect to an external monitor via VGA port or via a USB-VGA connector.

  • Microsoft Outlook tips and tricks for improving user experience?

    - by Roee Adler
    I'm one of those heavy Microsoft Outlook users, currently working on the 2007 version. God knows this tool is heavy and may impose problems. I wondered what the Super User crowd has to suggest in order to improve the usage experience. Several suggestions of my own: Always work in cached mode (Tools--Account Settings--Change--Use Cached Exchange Mode) Use Outlook's local archiving capabilities Use Outlook's RSS reader - it's simple and allows offline access to your feeds If you have e-mail subscriptions to magazines, blogs, etc. - create a subdirectory to keep them, and a rule to automatically move them there when they arrive (one rule per subscription, based on the sender e-mail.) You can also share suggestions that require configuration of Exchange Server, for those of us who can make bring them to their IT managers. What are your suggestions? PS: "Use Gmail" is not an accepted answer, some of us don't control what email system we use...

  • Unable to use Maya animation with scripts when imported to Unity

    - by keshk
    I am testing to import Maya animation over to Unity. I set up a simple cylinder with 2 bones and an IK handle. Made a simple animation where the cylinder bends and goes back to straight position over 24 frames. Following that, I selected everything and baked, all bones,ik,(animation by selecting all at the graph editor) and even the cylinder. I saved the scene and then select all and export as FBX with animation and bake checked. In unity imported it and at the preview able to see the animation. When I load the model into scene and play (after assigning the controller), able to see animation too. But now when I try to script it and control the animation, nothing happens. Even to test, I tried the following under the Update method. if(animation.isPlaying) Debug.Log("Animation Works"); else Debug.Log("Animation not working"); The bool doesn't even return true nor false. My animation is called "bend", thus just for try I did the following and nothing happens. animation.Play("bend"); Can please advice based on my steps, am I missing something. Do I need to add the controller or is that an unnecessary step? Did I screw up on the Maya part or the Unity part. Thanks for help.

  • Laptop VGA Output Stopped Working

    - by Jack7890
    I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

  • Cannot install FrontPage 2002 Server Extensions on Server 2003

    - by Sentax
    Hi everyone, I've followed the Microsoft article to install FPSE 2002 on my Windows 2003 server: To install and enable FrontPage 2002 Server Extensions 1. From the Start menu, click Control Panel. 2. Double-click Add or Remove Programs. 3. Click Add/Remove Windows Components. 4. In the Windows Components Wizard, double-click Application Server, double-click Internet Information Services, and then select the FrontPage 2002 Server Extensions check box. 5. Click OK twice, click Next, and then click Finish. But on step 4 "FrontPage 2002 Server Extensions" does not show up in the list in the IIS details window. How do I get FPSE 2002 installed on my server? From what I can understand it's supposed to be there and I just have to enable it. But that's not an option for me. Thanks.

  • IBM laptop remove access-connections

    - by Kevin
    I installed IBM Access Connections on my IBM t61 laptop to manage my wireless connections but it simply will not connect to my network. I want to uninstall it and try the Intel software which is capable to performing the same task. However, when I go into "Control Panel" - "Add/Remove Programs" and try to "Remove" this package, it simply opens up a screen and closes it immediately. This happens too fast for me to see whether its an error. Has anyone encountered this issue ? The event logs do not show any error.

  • Hot Off the Press - Oracle Exadata: A Data Management Tipping Point

    - by kimberly.billings
    Advances in data-management architecture - including CPU, memory, storage, I/O, and the database - have been steady but piecemeal. In this report, Merv Adrian describes how Oracle Exadata not only provides the latest technology in each part of the data-management architecture, but also integrates them under the full control of one vendor with a unified approach to leveraging the full stack. He writes, "the real "secret sauce" of Oracle Exadata V2 is the way in which these technologies complement each other to deliver additional performance and scalability." Merv interviews two Exadata customers, Banco Transylvania and TUI Netherlands, and concludes that early indications are that Oracle Exadata is delivering on its promise of extreme performance and scalability. His recommendation to IT is to target corporate applications with the biggest potential for speed-based enhancement, and consider whether Oracle Exadata V2 can cost-effectively enable new ways to use these for competitive advantage. Read the full report. var gaJsHost = (("https:" == document.location.protocol) ?

  • Folder Redirection won't load on Windows 7 Machine in Windows 2008 R2 Network

    - by leeand00
    Okay so redirected profiles don't load exactly, but the computer is joined to the network and it won't display any of the users files on their desktop that are in their redirected profile. I know this because we have a Terminal Server and when the user logs in there, her files appear. I checked the users' profile in Active Directory Users and Computers and compared it with a working users profile. When that didn't turn up any differences, I looked at her computer and found that on the Dial-in tab the Network Access Permission wasn't set to Control access through NPS Network Policy like it was on the other machines on the network; so I selected it, ran gpupdate /force on her machine and rebooted. This did not fix the issue. Is there anything else that could be preventing the redirected files on the users desktop from showing up when the user logs in?

  • Suggestions for Troubleshooting WIndows 7 lockups

    - by Craig L
    I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

  • How Do I Change the Windows7 LAN Proxy Config from the Command Line

    - by david.barkhuizen
    In Windows7, Is it possible to define/change the proxy config from the command line ? So, using the gui, I would go: Start Control Panel Network and Internet Internet Options Connections LAN Settings and then - enable/disable the proxy - define IP:port of proxy server But I would like to rather do this from the command line (so that I can run the command from a batch-file with a shortcut key - enabling me to switch proxy configs using a short-cut, rather than having to wade through the MS wizard). I've looked at using netsh.exe to change the settings for WinHTTP, but this seems to be thr wrong thing to do, as the WinHTTP setting do not appear to be related to the LAN settings. Much appreciated folks.
