• Preview Before You Paste with Live Preview in Office 2010

  - by DigitalGeekery

  Do you often find yourself frustrated that content you just copied and pasted didn’t turn out the way you expected? With the new Live Preview in Office 2010, you can preview how copied content will look when it’s pasted even between Office applications. Not every paste preview option will be available in every circumstance. The available options will be based on the applications being used and what content is copied. Copy your content like normal by right-clicking and selecting Copy, pressing Crtl + C, or selecting Copy from the Home tab. Next, select your location to paste the content. Now you can access the Paste Preview buttons either by selecting the Paste dropdown list from the Home tab…   …Or by right-clicking. As you hover your cursor over each of the Paste Options buttons, you will see a preview of what it will look like if you paste using that option. Click the corresponding button when you find the paste option you like. The “Paste” will paste all the content and formatting as you can see below. Values will paste values only, no formatting.   Formatting will paste only the formatting, no values. Hover over Paste Special to reveal any additional paste options. The process is similar in other Office applications. As you can see in the Word document below, Keep Text Only will paste the text, but not the orange color format from the original text.   Even after you’ve pasted, there is still time to change your mind. After you paste content you’ll see a Paste Option button near your content. If you don’t, you can pull it up by pressing the Ctrl key. Note: This is also available after using Ctrl + V to paste. Click to enable the dropdown and select one of the available options.   Using Live Paste Preview between multiple applications is just as easy. If we preview pasting the content from our Word document into PowerPoint by using the Keep Source Formatting option, we’ll see that the outcome looks awful. Selecting the Use Destination Theme will merge the text into the theme of the PowerPoint document and looks a lot better on our slide.   Live Paste Preview is a nice addition to Office 2010 and is sure to save time spent undoing the unexpected consequences of pasting content.

• SQLAuthority News – Amazon Gift Card Raffle for Beta Tester Feedback for NuoDB

  - by pinaldave

  As regular readers know I’ve been spending some time working with the NuoDB beta software. They contacted me last week and asked if I would give you a chance to try their new web-based console for their scalable, SQL-compliant database. They have just put out their final beta release, Beta 9.  It contains a preview of a new web-based “NuoConsole” that will replace and extend the functionality of their current desktop version.  I haven’t spent any time with the new console yet but a really quick look tells me it should make it easier to do deeper monitoring than the older one. It also looks like they have added query-level reporting through the console. I will try to play with it soon. NuoDB is doing a last, big push to get some more feedback from developers before they release their 1.0 product sometime in the next several weeks. Since the console is new, they are especially interested in some quick feedback on it before general availability. For SQLAuthority readers only, NuoDB will raffle off three $50 Amazon gift cards in exchange for your feedback on the NuoConsole preview. Here’s how to Enter Download NuoDBeta 9 here You must build a domain before you can start the console. Launch the Web Console. Windows Code: start java -jar jarnuodbwebconsole.jar Mac, Linux, Solaris, Unix Code: java -jar jar/nuodbwebconsole.jar Access the Web Console: Code: http://localhost:8080 When you have tried it out, go to a short (8 question) survey to enter the raffle Click here for the survey You must complete the survey before midnight EDT on October 17, 2012. Here’s what else they are saying about this last beta before general availability: Beta 9 now supports the Zend PHP framework so that PHP developers can directly integrate web applications with NuoDB. Multi-threaded HDFS support – NuoDB Storage Managers can now be configured to persist data to the high performance Hadoop distributed file system (HDFS). Beta 9 optimizes for multi-thread I/O streams at maximum performance. This enhancement allows users to make Hadoop their core storage with no extra effort which is a pretty cool idea. Improved Performance –On a single transaction node, Beta 9 offers performance comparable with MySQL and MariaDB. As additional nodes are added, NuoDB performance improves significantly at near linear scale. Query & Explain Plan Logging – Beta 9 introduces SQL explain plans for your queries. Qualify queries with the word “EXPLAIN” and NuoDB will respond with the details of the execution plan allowing performance optimization to SQL. Through the NuoConsole, you can now kill hung or long running queries. Java App Server Support – Beta 9 now supports leading Web JEE app servers including JBoss, Tomcat, and ColdFusion. They’ve also reported: Improved PHP/PDO drivers Support for Drupal Faster Ruby on Rails driver The Hibernate Dialect supports version 4.1 And good news for my readers: numerous SQL enhancements They will share the results of the web console feedback with me.  I’ll let you know how it goes. Also the winner of their last contest was Jaime Martínez Lafargue!  Do leave a comment here once you complete the survey.  Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: SQL Authority Tagged: NuoDB

• How to inhibit suspend temporarily?

  - by Zorn

  I have searched around a bit for this and can't seem to find anything helpful. I have my PC running Ubuntu 12.10 set up to suspend after 30 minutes of inactivity. I don't want to change that, it works great most of the time. What I do want to do is disable the automatic suspend if a particular application is running. How can I do this? The closest thing I've found so far is to add a shell script in /usr/lib/pm-utils/sleep.d which checks if the application is running and returns 1 to indicate that suspend should be prevented. But it looks like the system then gives up on suspending automatically, instead of trying again after another 30 minutes. (As far as I can tell, if I move the mouse, that restarts the timer again.) It's quite likely the application will finish after a couple of hours, and I'd rather my PC then suspended automatically if I'm not using it at that point. (So I don't want to add a call to pm-suspend when the application finishes.) Is this possible? Any advice would be appreciated. Cheers. EDIT: As I noted in one of the comments below, what I actually wanted was to inhibit suspend when my PC was serving files over NFS; I just wanted to focus on the "suspend" part of the question because I already had an idea how to solve the NFS part. Using the 'xdotool' idea given in one of the answers, I have come up with the following script which I run from cron every few minutes. It's not ideal because it stops the screensaver kicking in as well, but it does work. I need to have a look at why 'caffeine' doesn't correctly re-enable suspend later on, then I could probably do better. Anyway, this does seem to work, so I'm including it here in case anyone else is interested. #!/bin/bash # If the output of this function changes between two successive runs of this # script, we inhibit auto-suspend. function check_activity() { /usr/sbin/nfsstat --server --list } # Prevent the automatic suspend from kicking in. function inhibit_suspend() { # Slightly jiggle the mouse pointer about; we do a small step and # reverse step to try to stop this being annoying to anyone using the # PC. TODO: This isn't ideal, apart from being a bit hacky it stops # the screensaver kicking in as well, when all we want is to stop # the PC suspending. Can 'caffeine' help? export DISPLAY=:0.0 xdotool mousemove_relative --sync -- 1 1 xdotool mousemove_relative --sync -- -1 -1 } LOG="$HOME/log/nfs-suspend-blocker.log" ACTIVITYFILE1="$HOME/tmp/nfs-suspend-blocker.current" ACTIVITYFILE2="$HOME/tmp/nfs-suspend-blocker.previous" echo "Started run at $(date)" >> "$LOG" if [ ! -f "$ACTIVITYFILE1" ]; then check_activity > "$ACTIVITYFILE1" exit 0; fi /bin/mv "$ACTIVITYFILE1" "$ACTIVITYFILE2" check_activity > "$ACTIVITYFILE1" if cmp --quiet "$ACTIVITYFILE1" "$ACTIVITYFILE2"; then echo "No activity detected since last run" >> "$LOG" else echo "Activity detected since last run; inhibiting suspend" >> "$LOG" inhibit_suspend fi

• Create Panoramic Photos with Windows Live Photo Gallery

  - by Matthew Guay

  Have you ever wanted to capture the view from a mountain or the full size of a building?  Here’s how you can stitch multiple shots together into the perfect panoramic picture for free with Windows Live Photo Gallery. Getting Started First, make sure you have Windows Live Photo Gallery installed (link below).  Live Photo Gallery is part of the Windows Live Essentials suite, you can select other programs to install along with it if you want. Make sure to uncheck setting your home page to MSN and setting your search provider as Bing if you don’t want them changed.   Now, make sure you have pictures that will work good for a panorama.  These need to be taken from the same spot, and the edges of the pictures need to overlap so the program can find where the pictures connect.  Here we have taken pictures inside a building with a cell phone camera. Make your Panorama Open Live Photo Gallery, and find the pictures you want to use in your panorama.  It will automatically index and display all of the photos in your Pictures folder or Library if you’re using Windows 7. If your pictures are saved elsewhere, add that folder to Photo Gallery.  Click File, Include a folder in the gallery, and select the correct folder at the prompt. Now select all of the pictures that you will use in your panorama.  You can easily do this by clicking the checkbox on each picture that appears when you hover over it.    Once all of the pictures are selected, click Make in the menu bar and select Create panoramic photo… Alternately, right-click on any of the pictures you’ve selected, and click Create panoramic photo… Live Photo Gallery will analyze your photos and compost them together to create a panorama.  The amount of time it takes will vary depending on the number of photos, size of the pictures, and computer speed. When it’s finished making the panorama, you’ll be prompted to enter a file name and save the picture. Your new panorama picture will open as soon as it’s saved.  Depending on your shots, the picture may have quite a bit of black space around the edges where each picture didn’t cover the exact same amount of area. To correct this, click Fix on the menu bar, and then select Crop Photo in the sidebar that opens. Select the center of the picture with the crop tool, and click Apply when you’ve got the selection you want. Live Photo Gallery automatically saves your picture changes, and you can revert back to the original picture if you wish. Now you’ve got a nice panoramic shot, trimmed and ready to print, share, and more. Conclusion Panoramic shots are great ways to capture your whole surroundings, whether it’s a sports stadium, mall, or a scenic mountain view.  They can also be a great way to capture more with low-resolution cameras.

• SQLAuthority News – Getting Ready to Learn SQL Server

  - by pinaldave

  If you have read my earlier blog post you must be aware of how I am always eager to learn new things. I have signed up for three days learning course at Koenig Solutions for End to End SQL Server Business Intelligence. You may wonder why I sign up for the course on SQL Server when it seems that I know a lot about it. Well, the belief is incorrect that I know a lot. I think there are plenty of things which I have been dreaming to learn. Why am I learning SQL Server? First of all – I do not know everything and second it is always a good idea to learn more. No matter how old we get or how much we think we know – there are always details which we can learn and refresh few concepts. Learning is never ending process philosophically but it is true as well in reality. SQL Server 2012 is already released earlier this year and there are plenty of enhancements released. Recently I was going over the list of the all the new feature and enhancement and I realized that there few things about SQL Server 2008 R2 I never got a chance to have a hand’s on experience and we have entered into the era of SQL Server 2012. I feel a bit bad about it and I decided to make it a priority for me to learn all the missing experiences. Quick Action – Registration The very same day I called up my friend who owns Koenig Solution and expressed my concern and requested his help. During my early career when I was a SQL Server Trainer, we had some good synergy between us and now they are very successful offshore training company by having a physical location in Delhi,  Goa, Dahradun, Shimla, Goa and Bangalore. I quickly visited their Bangalore Center and paid my fees for learning SQL Server Business Intelligence course. Very next second I got call from my friend suggesting that I learn this course from Delhi instead of Bangalore. As per him I should travel to Delhi and learn the course how other students are learning “Away from Home”. This made sense as I stay in Bangalore and if I return home after a long day of learning, I will be not able to practice for the next day as there will be “sweet distraction” of the family. Well I opted for Delhi. What Registration Fees Included I learned from registration processes that the following were included in the fees. 3 meals every day (hearty breakfast, lunch from premium restaurants and home cooked like dinner) Airport pick up and drop Hotel Stay Internet at hotel and at learning institute Unlimited coffee and snacks at learning institute Printed Learning Material Certification Fees (if applicable) Learning material … And of course classroom training I thought registration process was over when I paid fees. Well, I was in for a very nice surprise. Registration Experience – Bliss! Within few hours I received emails from Center Manager of Delhi with all the necessary details I need to know about my learning experience. The email contained following information in detail and it blew me away. Details of the pick up from airport – driver information Details of Delhi and important information List of all the important people and emergency contact details Internet connection details Detail of the trainer and all the training details and lots of other relevant information Well so far everything looks great. Tomorrow I will reach to Delhi and I will share how things go on. Any suggestion for things to do in Delhi?

• Achieve Named Criteria with multiple tables in EJB Data control

  - by Deepak Siddappa

  In EJB create a named criteria using sparse xml and in named criteria wizard, only attributes related to the that particular entities will be displayed.  So here we can filter results only on particular entity bean. Take a scenario where we need to create Named Criteria based on multiple tables using EJB. In BC4J we can achieve this by creating view object based on multiple tables. So in this article, we will try to achieve named criteria based on multiple tables using EJB.Implementation StepsCreate Java EE Web Application with entity based on Departments and Employees, then create a session bean and data control for the session bean.Create a Java Bean, name as CustomBean and add below code to the file. Here in java bean from both Departments and Employees tables three fields are taken. public class CustomBean { private BigDecimal departmentId; private String departmentName; private BigDecimal locationId; private BigDecimal employeeId; private String firstName; private String lastName; public CustomBean() { super(); } public void setDepartmentId(BigDecimal departmentId) { this.departmentId = departmentId; } public BigDecimal getDepartmentId() { return departmentId; } public void setDepartmentName(String departmentName) { this.departmentName = departmentName; } public String getDepartmentName() { return departmentName; } public void setLocationId(BigDecimal locationId) { this.locationId = locationId; } public BigDecimal getLocationId() { return locationId; } public void setEmployeeId(BigDecimal employeeId) { this.employeeId = employeeId; } public BigDecimal getEmployeeId() { return employeeId; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getFirstName() { return firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getLastName() { return lastName; } } Open the sessionEJb file and add the below code to the session bean and expose the method in local/remote interface and generate a data control for that. Note:- Here in the below code "em" is a EntityManager. public List<CustomBean> getCustomBeanFindAll() { String queryString = "select d.department_id, d.department_name, d.location_id, e.employee_id, e.first_name, e.last_name from departments d, employees e\n" + "where e.department_id = d.department_id"; Query genericSearchQuery = em.createNativeQuery(queryString, "CustomQuery"); List resultList = genericSearchQuery.getResultList(); Iterator resultListIterator = resultList.iterator(); List<CustomBean> customList = new ArrayList(); while (resultListIterator.hasNext()) { Object col[] = (Object[])resultListIterator.next(); CustomBean custom = new CustomBean(); custom.setDepartmentId((BigDecimal)col[0]); custom.setDepartmentName((String)col[1]); custom.setLocationId((BigDecimal)col[2]); custom.setEmployeeId((BigDecimal)col[3]); custom.setFirstName((String)col[4]); custom.setLastName((String)col[5]); customList.add(custom); } return customList; } Open the DataControls.dcx file and create sparse xml for customBean. In sparse xml navigate to Named criteria tab -> Bind Variable section, create two binding variables deptId,fName. In sparse xml navigate to Named criteria tab ->Named criteria, create a named criteria and map the query attributes to the bind variables. In the ViewController create a file jspx page, from data control palette drop customBeanFindAll->Named Criteria->CustomBeanCriteria->Query as ADF Query Panel with Table. Run the jspx page and enter values in search form with departmentId as 50 and firstName as "M". Named criteria will filter the query of a data source and display the result like below.

• ADF Enterprise Application Development - Made Simple (Book Review)

  - by Frank Nimphius

    Sten E. Vesterli wrote the "Oracle ADF Enterprise Application Development – Made Simple" book published by Packt Publishing in 2011 http://www.packtpub.com/oracle-adf-enterprise-application-development/book A common question on OTN, but also when talking to clients or customers is about where and how to start your ADF application development. Especially when the current programming background is not in Java, but 4 GL or PLSQL, developers often look for answers to the following questions: · How long does it take to learn Oracle ADF ? · How long does it take to replace a Forms application with ADF ? · How many developers do I need? · Do I need to know Java to use ADF and if yes, how good do I need to know this? · How do I structure my programming files, organizing them in JDeveloper work spaces, projects and libraries? · What is best practices for naming Java packages and how to void naming conflicts in ADF in general? · How many Application Modules do I need or should I create? · How to test applications? Sten Vesterli answers all of the above questions and more in his book http://www.packtpub.com/oracle-adf-enterprise-application-development/book , which makes it great value add to the 3 existing Oracle ADF books. In order of complexity (which also is the order in which reading the available Oracle ADF books makes sense), in my opinion, Sten's book should come second – though it also is useful to those that are already more advanced with Oracle ADF. So if you are absolutely new to Oracle ADF, then the order of books to read to get you up on an expert level should be: 1. Grant Ronald; "Quick Start Guide to Oracle Fusion Development: Oracle JDeveloper and Oracle ADF" (McGraw Hill 2010) 2. Sten Vesterli; "Oracle ADF Enterprise Application Development – Made Simple" (Packt Publishing 2011) 3. Duncan Mills, Peter Koletzke; " Oracle JDeveloper 11g Handbook: A Guide to Fusion Web Development" (McGraw Hill 2009) 4. Frank Nimphius, Lynn Munsinger; " Oracle Fusion Developer Guide: Building Rich Internet Applications with Oracle ADF Business Components and Oracle ADF Faces" (McGraw Hill 2010) If you are not new to Oracle ADF and Orace JDeveloper, then buy Sten Vesterli's book anyway. It is worth it and you want to have it on your book shelf. See below the table of content to get a better idea of what this book covers: · Chapter 1: The ADF Proof of Concept · Chapter 2: Estimating the Effort · Chapter 3: Getting Organized · Chapter 4: Productive Teamwork · Chapter 5: Prepare to Build · Chapter 6: Building the Enterprise Application · Chapter 7: Testing your Application · Chapter 8: Look and Feel · Chapter 9: Customizing the Functionality · Chapter 10: Securing your ADF Application · Chapter 11: Package and Deliver · Appendix: Internationalization The book is written with a lot of good humor, which makes the read very enjoyable (from a geek's perspective, of course). My favorite quote – just in case you are interested - is from page 97, when Sten talks about getting organized: " Stop sending e-mails to your team. Just stop it. E-mail is so last century.…" So true, so true! This quote's runner up is the "boss key" on page 128 where Sten talks about productivity and how Oracle Team Productivity Center (TPC) can help you with this. Quotes like these stick to your brains and make sure you never forget. Go for it!

• NetBeans PHP Community Council

  - by Tomas Mysik

  Hi all, today we would like to inform all of you that now you have a chance to improve NetBeans via NetBeans PHP Community Council. The author of this activity is Timur Poperecinii and he would like to tell you a few words about it. Hello passionate technical people, First of all let me introduce myself: my name is Timur, I’m a developer from Moldova (that little country between Romania and Ukraine), I develop mostly in .NET and JQuery, but I love to learn more, not being an expert I am familiar with Java (Struts2, Play), PHP (Symfony2), Ruby (Rails), Sencha Touch 2 and other technologies. I was “introduced” in PHP recently by a client of mine who requested to make the work specifically in PHP. Let me tell you a little story about my experience with open source and IDEs: when I was studying in university in 2007 I think, I did a simple little application in PHP and thought “Damn, if only there was a good IDE for PHP so I could relax and no having to remember all the function names”, then when I searched on internet pretty much everyone was using Vim or Emacs on Linux, but it had no autocomplete anyway, just syntax highlighting. I remember using some tool like Notepad++ I think. Nowadays everything changed, we have highlighting and autocomplete for about all standard things in PHP in many IDEs. I use NetBeans for PHP, and I really am happy with the experience I have there with standard PHP code, but for frameworks I still think there is lots of room for improvements. For example we have some Symfony 2 and Twig support. But I’d love to see more of that coming, for example I’m a big fan of file templates, where the main goal is to not waste time on writing over and over again something that can be generated, and it counts even more when you don’t have a lot of autocomplete. So what I thought, “Hey I know Java a little, and NetBeans has plugins, so may be it worth trying to do a file templates plugin”, and so I did, you can find details about my Unified Udevi Symfony2 Plugin for NetBeans 7.2 on my blog. It wasn’t hard, and it even was fun! Give back to open source Now think a little, NetBeans is an open source project and PHP support is just a part of it, so the resources are pretty limited in this area. But we as a community that uses this product, want to have the best possible experience with PHP and frameworks(!!!). So why don’t we GIVE BACK TO OPENSOURCE ? Imagine an IDE that can do all the things you wanted + it is free. Now how far is NetBeans from that point? I guess not so far – you might miss a little niche thing that you use on a daily basis, but then the question appears why don’t you make it happen on your own? NetBeans PHP Community Council What I proposed is to create a NetBeans PHP Community Council that will be formed of people willing to change something, willing to create plugins for their own needs and for the needs of the community, test the plugins created by them too, and basically evolve NetBeans in direction they want to reach. I already talked with the NetBeans PHP team. They are only happy to help this Council, with technical advises, opening some APIs we might need to have access to, and other things. One important thing to mention is that this Council is a Community project, so though we’ll have direct discussions with NetBeans PHP Dev team, NetBeans is not the leading force here, it is the community. You can see more details about the goals and structure I proposed at NetBeans PHP Community Council wiki page. We use this mail list: [email protected] for discussions and topics related to the Council. How can I join To join the NetBeans PHP Community Council please send an email to [email protected] with the subject of the mail starting with [Council New Member]. You can subscribe to this mail list here:http://netbeans.org/projects/php/lists. in your mail please indicate your location, age and experience both in Java and PHP. I need these data to assign you to a team. A response will be send to you with your next assignment and some people to contact. I really hope that you’ll make a step forward and try to make your everyday use of NetBeans even more fun.

• Jersey non blocking client

  - by Pavel Bucek

  Although Jersey already have support for making asynchronous requests, it is implemented by standard blocking way - every asynchronous request is handled by one thread and that thread is released only after request is completely processed. That is OK for lots of cases, but imagine how that will work when you need to do lots of parallel requests. Of course you can limit (and its really wise thing to do, you do want control your resources) number of threads used for asynchronous requests, but you'll get another maybe not pleasant consequence - obviously processing time will incerase. There are few projects which are trying to deal with that problem, commonly named as async http clients. I didn't want to "re-implement a wheel" and I decided I'll use AHC - Async Http Client made by Jeanfrancois Arcand. There is also interesting implementation from Apache - HttpAsyncClient, but it is still in "very early stages of development" and others haven't been in similar or better shape as AHC. How this works? Non-blocking clients allow users to make same asynchronous requests as we can do with standard approach but implementation is different - threads are better utilized, they don't spend most of time in idle state. Simply described - when you make a request (send it over the network), you are waiting for reply from other side. And there comes main advantage of non-blocking approach - it uses these threads for further work, like making other requests or processing responses etc.. Idle time is minimized and your resources (threads) will be far better used. Who should consider using this? Everyone who is making lots of asynchronous requests. I haven't done proper benchmark yet, but some simple dumb tests are showing huge improvement in cases where lots of concurrent asynchronous requests are made in short period. Last but not least - this module is still experimental, so if you don't like something or if you have ideas for improvements/any feedback, feel free to comment this blog post, send mail to users@jersey.java.net or contact me personally. All feedback is greatly appreciated! maven dependency (will be present in java.net maven 2 repo by the end of the day): link: http://download.java.net/maven/2/com/sun/jersey/experimental/jersey-non-blocking-client <dependency> <groupId>com.sun.jersey.experimental</groupId> <artifactId>jersey-non-blocking-client</artifactId> <version>1.9-SNAPSHOT</version> </dependency> code snippet: ClientConfig cc = new DefaultNonBlockingClientConfig(); cc.getProperties().put(NonBlockingClientConfig.PROPERTY_THREADPOOL_SIZE, 10); // default value, feel free to change Client c = NonBlockingClient.create(cc); AsyncWebResource awr = c.asyncResource("http://oracle.com"); Future<ClientResponse> responseFuture = awr.get(ClientResponse.class); // or awr.get(new TypeListener<ClientResponse>(ClientResponse.class) { @Override public void onComplete(Future<ClientResponse> f) throws InterruptedException { ... } }); javadoc (temporary location, won't be updated): http://anise.cz/~paja/jersey-non-blocking-client/

• Uninstall, Disable, or Remove Windows 7 Media Center

  - by Mysticgeek

  Although Windows 7 Media Center has improved a lot over previous versions of Windows, but you might want to disable it for different reasons. Here we take a look at a couple of methods to get rid of it. There are a variety of reasons you might want to disable Windows 7 Media Center. Maybe you own a business and don’t want it to run on the machines. Or perhaps you don’t use it at all and just don’t want it around. Turn Off WMC Using Programs and Features Probably the easiest way to get rid of it on all versions of Windows 7 is to open Control Panel and select Programs and Features. This method is similar to disabling Internet Explorer 8 in Windows 7. On the left hand panel click on Turn Windows Features on or off. Scroll down to Media Features and expand the folder. Then Uncheck Windows Media Center… You’ll get a verification message making sure you want to disable it, click Yes. Then the box next to Windows Media Center will be empty…click OK. Wait while WMC is disabled… To complete the process a reboot is required. After getting back from the restart, the WMC icon will be gone and there won’t be any way to launch it. Re-enable WMC If you want to re-enable it, just go back in and recheck it. Again you’ll need to wait while it’s configured, but when it’s done, a restart is not required.   Disable Media Center Using Group Policy Note: This process uses Group Policy Editor which is not available in Home versions of Windows 7. Click on the Start menu and type gpedit.msc into the Search box and hit Enter. Now navigate to User Configuration \ Administrative Templates \ Windows Components \ Windows Media Center. Double-click on Do not allow Windows Media Center to run. Then select the radio button next to Enabled, click OK and close out of Group Policy Editor. Now if a user tries to launch WMC they will get the following message. Conclusion If you’re not a fan of Windows Media Center or want to disable it for whatever reason, the process is simple and there are a couple of ways you can do it. WMC is not included in Starter or Home Basic versions of Windows 7. If you’re new to Windows 7 Media Center, you might want to check out our guide on getting started and setting up live TV.

• Share Folders & Files Between Vista and XP Machines

  - by Mysticgeek

  Since Microsoft has three operating systems in use, chances are you’ll find yourself needing to share files between XP, Vista, Windows 7, or some combination of the three. Here we take a look at sharing between a Vista and XP on your home network. Share Without Password Protected Sharing If you’re not worried about who’s accessing the files and folders, the easiest method is to disable Password Protected Sharing. So on the Vista machine open Network and Sharing Center. Under Sharing and Discovery make sure Network Discovery, File Sharing, and, Public Folder Sharing are turned on. Also turn off Password Protected Sharing… Now go into the Vista Public folder, located in C:\Users\Public, and add what you want to share or create a new folder. In this example we created a new folder called XP_Share and added some files to it. On the XP machine go into My Network Places and under Network Tasks click on View Workgroup Computers. Now you’ll see all of the computers on your network which should be part of the same Workgroup. Here we need to double-click on the Vista computer. And there we go…no password to enter so we can access the XP_Share folder or anything else that is located in the Public folder. Share with Password Protected Sharing If you want to keep Password Protected Sharing turned on, then we need to do things a little different. When it’s turned on and you try to access the Vista machine from XP, you’re prompted for a password, and no matter what you think the credentials are, you can’t get access…very annoying. So what we need to do is add the XP Machine as a user. Right-click on Computer from the Start Menu or desktop icon and select Manage from the context menu. The Computer Management screen opens up and you want to expand Local Users and Groups, then the Users folder. Then right-click any open area an select New User. Now create a new user name and password, you can also fill in the other fields if you want. Then make sure to uncheck User must change password at next logon and check the box next to Password never expires. Click the Create button and close out of the New User screen. You’ll then see the new user we created in the list and you can close out of the Computer Management window. Now back on the XP computer when you double-click on the Vista machine, your prompted to log in. Just type in the username and password you just created. Now you’ll have access to the Public folder contents. Set up Sharing on XP If you want to access a shared folder from the Vista computer located on the XP machine, it’s the same process in reverse. On the XP computer in Shared Documents, right-click on the folder you want to share and select Sharing and Security. Then select the radio button next to Share this folder and click Ok. Go into Computer Management and create a new user… Now from the Vista machine double click on the XP machine icon, enter the password, then access the folders and files you need. If you have multiple versions of Windows on your home network, you’ll now be able to access files and folders from each of them.

• Tips &amp; Tricks: How to crawl a SSL enabled Oracle E-Business Suite

  - by Rajesh Ghosh

  Oracle E-Business Suite can be integrated with Oracle Secure Enterprise Search for a superior end user experience and enhanced data retrieval capabilities. Before end-users can perform search operations, data has to be crawled and indexed into Oracle SES server. However if the Oracle E-Business Suite instance is on SSL, some additional configurations are needed in Oracle SES server as well as in Oracle Search Modeler, before a search object can be deployed and crawled. The process involves the following steps: Step 1: Export the SSL certificate of Oracle E-Business Suite Access the Oracle E-business Suite instance from a web browser. You should be able to locate a security or certificate icon somewhere in the browser toolbar or status bar, depending on which browser you are using. Click on it and you should be able to view the certificate as well as export it to a local file. While exporting make sure that you use “DER encoded” format. Step 2: Import the SSL certificate into Oracle Secure Enterprise server’s java key-store Oracle SES (10.1.8.4) by default ships a JDK under $ORACLE_HOME. The Oracle SES mid-tier uses this jdk to start the oc4j container services. In this step the Oracle E-Business Suite’s SSL certificate which has been exported in step #1, has to be imported into the Oracle SES server’s java key store. Perform the following: Copy the certificate file onto the server where Oracle SES server is running; under $ORACLE_HOME/jdk/jre/lib/security/cacerts. “ORACLE_HOME” points to the Oracle SES oracle home. Set the JAVA_HOME environment variable to $ORACLE_HOME/jdk. Append $JAVA_HOME/bin to the PATH environment variable Issue the command :  “keytool -import -keystore keystore.jks -trustcacerts -alias myOHS –file ebs.crt” . Please substitute “ebs.crt” with the name of the certificate file you copied in step #2.1. The default key-store password “changeit”. Enter the same when prompted. If successful this process will end with a message saying “certificate successfully imported”. Step 3: Import the SSL certificate into Search Modeler java key-store Unlike Oracle SES, Search Modeler is not shipped with a bundled JDK. If you are using standalone OC4J, then you actually use an external JDK to start the oc4j container services. If you are using IAS instance then the JDK comes bundled with the IAS installation. Perform the following: Copy the certificate file onto the server where Search Modeler application is running; under $JDK_HOME/jre/lib/security/cacerts. “JDK_HOME” points to the JDK directory depending on whether you are using external JDK or a bundled one. Set the JAVA_HOME environment variable to JDK directory. Append $JAVA_HOME/bin to the PATH environment variable Issue the command :  “keytool -import -keystore keystore.jks -trustcacerts -alias myOHS –file ebs.crt” . Please substitute “ebs.crt” with the name of the certificate file you copied in step #3.1. The default key-store password “changeit”. Enter the same when prompted. If successful this process will end with a message saying “certificate successfully imported”. Once you have completed the above steps successfully, you can deploy the search objects using Search Modeler and then start crawling them as well.

• JFall 2012

  - by Geertjan

  JFall 2012 was over far too soon! Seven tracks going on simultaneously in a great location, with many artifacts reminding me of JavaOne, and nice snacks and drinks afterwards. The day started, as such things always do, with a keynote. Thanks to @royvanrijn for the photo below, I didn't take any myself and without a picture this report might have been too dry: What you see above is Steve Chin riding into the keynote hall on his NightHacking bike. The keynote was interesting, I can't be too complimentary about it, since I was part of it myself. Bert Ertman introduced the day and then Steve Chin took over, together with Sharat Chander, Tom Eugelink, Timon Veenstra, and myself. We had a strict choreography for the keynote, one that would ensure a lot of variation and some unexpected surprises, such as Steve being thrown off the stage a few times by Bert because of mentioning JavaOne too many times, rather than the clearly much cooler JFall. Steve talked about JavaOne and the direction Java is headed in, Sharat talked about JavaME and embedded devices, Steve and Tom did a demo involving JavaFX, I did a Project Easel demo, and Timon from Ordina talked about his Duke's Choice Award winning AgroSense project. I think the Project Easel demo (which I repeated later in a screencast for Parleys arranged by Eugene Boogaart) came across well and several people I spoke to especially like the roundtrip/bi-directional work that can be done, from browser to IDE and back again, very simply and intuitively. (In a long conversation on the drive back home afterwards, the scenario of a designer laying out the UI in HTML and then handing the HTML to a developer for back-end work, a developer who would then find it convenient to open the HTML in a browser and quickly navigate from the browser to the resources within the IDE, was discussed and considered to be extremely interesting and worth considering adopting NetBeans for, for no other reason than that.) Later I attended a session by David Delabassee on Java EE 7, Hans Dockter on Gradle, and Sander Mak on cross-build injection attacks. I was sorry to have missed Martijn Verburg's session, which sounded like it was really fantastic, among others, such as Gerrit Grunwald. I did a session too, entitled "Unlocking the Java EE 6 Platform", which was very well attended, pretty much a full room, and the demo went very smoothly. I talked to many people, e.g., a long time with Hans Dockter about how cool Gradle is and how great the Gradle/NetBeans plugin is turning out to be. I also had a long conversation (and did a demo) with Chris Chedgey, from Structure101, after his session, which was incredibly well attended; very interesting how popular modularity is. I met several people for the first time, as well as some colleagues from past places I've worked at. All in all, it was a great conference, unfortunately too short, which was very well attended (clearly over 1000) people, with several international speakers, as well as international attendees such as Mattias Karlsson, Sweden JUG leader. And, unsurprisingly, I came across NetBeans Platform applications again, none of which I had ever heard of before. In each case, "our fat client application" was mentioned in passing, never as a main application, and never in a context where there are plans for the application to be migrated to the web or mobile, simply because doing so makes no business sense at all. Great times at JFall, looking forward to meeting with some of the people I met again soon.

• Running a WebLogic Portal (WLP) 10.3.4 Domain as a Windows Service

  - by user647124

  To start a WLP server as a Windows service it is simplest to make your own script based on the provided standard script located at WL_HOME\server\bin\installSvc.cmd. The standard script works fine for a plain WLS domain, but lacks some classpath and options necessary for WLP.Start by making a copy of the installSvc.cmd script and naming it something specific to your domain.Next, just under SETLOCAL you will find where WL_HOME is defined. Here you will add the definitions you would normally add in a script that later calls installSvc.cmd (as per the standard documentation). set DOMAIN_NAME=gnma_test_domainset USERDOMAIN_HOME=D:\my_test_domainset SERVER_NAME=AdminServerset WLS_USER=weblogicset WLS_PW=gnmaAdmin01set PRODUCTION_MODE=trueset MEM_ARGS=-Xms512m –Xmx512mset MW_HOME=C:\Oracle\Middleware Note: I had heard of people using this approach who had issues with the length of the command line. This may be due to their use of the default domain path. In the example above, I use a shorter path.At this point, edit the DOMAIN_HOME\bin\startWebLogic.cmd and set it to echo both the classpath and the options. Then start the domain and capture the output of those echoes, then shut the domain back down. Now REM out the existing CLASSPATH definition, then use the outputs you captured earlier to set the CLASSPATH and JAVA_OPTIONS like this: REM set CLASSPATH=%WEBLOGIC_CLASSPATH%;%CLASSPATH%; C:\Oracle\Middleware\wlportal_10.3\portal\lib\security\wsrp-security-providers.jarset CLASSPATH=%MW_HOME%\patch_wls1034\profiles\default\sys_manifest_classpath\weblogic_patch.jar;%MW_HOME%\patch_wlp1034\profiles\default\sys_manifest_classpath\weblogic_patch.jar;%MW_HOME%\patch_oepe1111\profiles\default\sys_manifest_classpath\weblogic_patch.jar;%MW_HOME%\patch_ocm1033\profiles\default\sys_manifest_classpath\weblogic_patch.jar;%MW_HOME%\JROCKI~1.1-3\lib\tools.jar;%WL_HOME%\server\lib\weblogic_sp.jar;%WL_HOME%\server\lib\weblogic.jar;%MW_HOME%\modules\features\weblogic.server.modules_10.3.4.0.jar;%WL_HOME%\server\lib\webservices.jar;%MW_HOME%\modules\ORGAPA~1.1/lib/ant-all.jar;%MW_HOME%\modules\NETSFA~1.0_1/lib/ant-contrib.jar;%WL_HOME%\common\derby\lib\derbyclient.jar;%WL_HOME%\server\lib\xqrl.jar;%WL_HOME%\server\lib\xquery.jar;%WL_HOME%\server\lib\binxml.jarset JAVA_OPTIONS= -Xverify:none -ea -da:com.bea... -da:javelin... -da:weblogic... -ea:com.bea.wli... -ea:com.bea.broker... -ea:com.bea.sbconsole... -Dplatform.home=%WL_HOME% -Dwls.home=%WL_HOME%\server -Dweblogic.home=%WL_HOME%\server -Dweblogic.wsee.bind.suppressDeployErrorMessage=true -Dweblogic.wsee.skip.async.response=true -Dweblogic.management.discover=true -Dwlw.iterativeDev=true -Dwlw.testConsole=true -Dwlw.logErrorsToConsole=true -Dweblogic.ext.dirs=%MW_HOME%\patch_wls1034\profiles\default\sysext_manifest_classpath;%MW_HOME%\patch_wlp1034\profiles\default\sysext_manifest_classpath;%MW_HOME%\patch_oepe1111\profiles\default\sysext_manifest_classpath;%MW_HOME%\patch_ocm1033\profiles\default\sysext_manifest_classpath;%MW_HOME%\wlportal_10.3\p13n\lib\system;%MW_HOME%\wlportal_10.3\light-portal\lib\system;%MW_HOME%\wlportal_10.3\portal\lib\system;%MW_HOME%\wlportal_10.3\info-mgmt\lib\system;%MW_HOME%\wlportal_10.3\analytics\lib\system;%MW_HOME%\wlportal_10.3\apps\lib\system;%MW_HOME%\wlportal_10.3\info-mgmt\deprecated\lib\system;%MW_HOME%\wlportal_10.3\content-mgmt\lib\system -Dweblogic.alternateTypesDirectory=%MW_HOME%\wlportal_10.3\portal\lib\securityAnd that's it. Looks really simple, but it took me quite some time to gather all the necessary pieces in order to make it work. Hopefully you find this before you went through half as much research.The example here uses a domain with only the Admin server and no managed servers. For a variety of reasons I only want the Admin server to be run as a service. The standard documentation along with the example above should allow you to expand this to include managed servers should you feel the need.

• EPM 11.1.2.2 Architecture: Financial Performance Management Applications

  - by Marc Schumacher

   Financial Management can be accessed either by a browser based client or by SmartView. Starting from release 11.1.2.2, the Financial Management Windows client does not longer access the Financial Management Consolidation server. All tasks that require an on line connection (e.g. load and extract tasks) can only be done using the web interface. Any client connection initiated by a browser or SmartView is send to the Oracle HTTP server (OHS) first. Based on the path given (e.g. hfmadf, hfmofficeprovider) in the URL, OHS makes a decision to forward this request either to the new Financial Management web application based on the Oracle Application Development Framework (ADF) or to the .NET based application serving SmartView retrievals running on Internet Information Server (IIS). Any requests send to the ADF web interface that need to be processed by the Financial Management application server are send to the IIS using HTTP protocol and will be forwarded further using DCOM to the Financial Management application server. SmartView requests, which are processes by IIS in first row, are forwarded to the Financial Management application server using DCOM as well. The Financial Management Application Server uses OLE DB database connections via native database clients to talk to the Financial Management database schema. Communication between the Financial Management DME Listener, which handles requests from EPMA, and the Financial Management application server is based on DCOM.  Unlike most other components Essbase Analytics Link (EAL) does not have an end user interface. The only user interface is a plug-in for the Essbase Administration Services console, which is used for administration purposes only. End users interact with a Transparent or Replicated Partition that is created in Essbase and populated with data by EAL. The Analytics Link Server deployed on WebLogic communicates through HTTP protocol with the Analytics Link Financial Management Connector that is deployed in IIS on the Financial Management web server. Analytics Link Server interacts with the Data Synchronisation server using the EAL API. The Data Synchronization server acts as a target of a Transparent or Replicated Partition in Essbase and uses a native database client to connect to the Financial Management database. Analytics Link Server uses JDBC to connect to relational repository databases and Essbase JAPI to connect to Essbase.  As most Oracle EPM System products, browser based clients and SmartView can be used to access Planning. The Java based Planning web application is deployed on WebLogic, which is configured behind an Oracle HTTP Server (OHS). Communication between Planning and the Planning RMI Registry Service is done using Java Remote Message Invocation (RMI). Planning uses JDBC to access relational repository databases and talks to Essbase using the CAPI. Be aware of the fact that beside the Planning System database a dedicated database schema is needed for each application that is set up within Planning.  As Planning, Profitability and Cost Management (HPCM) has a pretty simple architecture. Beside the browser based clients and SmartView, a web service consumer can be used as a client too. All clients access the Java based web application deployed on WebLogic through Oracle HHTP Server (OHS). Communication between Profitability and Cost Management and EPMA Web Server is done using HTTP protocol. JDBC is used to access the relational repository databases as well as data sources. Essbase JAPI is utilized to talk to Essbase.  For Strategic Finance, two clients exist, SmartView and a Windows client. While SmartView communicates through the web layer to the Strategic Finance Server, Strategic Finance Windows client makes a direct connection to the Strategic Finance Server using RPC calls. Connections from Strategic Finance Web as well as from Strategic Finance Web Services to the Strategic Finance Server are made using RPC calls too. The Strategic Finance Server uses its own file based data store. JDBC is used to connect to the EPM System Registry from web and application layer.  Disclosure Management has three kinds of clients. While the browser based client and SmartView interact with the Disclosure Management web application directly through Oracle HTTP Server (OHS), Taxonomy Designer does not connect to the Disclosure Management server. Communication to relational repository databases is done via JDBC, to connect to Essbase the Essbase JAPI is utilized.

• Why is there no service-oriented language?

  - by Wolfgang

  Edit: To avoid further confusion: I am not talking about web services and such. I am talking about structuring applications internally, it's not about how computers communicate. It's about programming languages, compilers and how the imperative programming paradigm is extended. Original: In the imperative programming field, we saw two paradigms in the past 20 years (or more): object-oriented (OO), and service-oriented (SO) aka. component-based (CB). Both paradigms extend the imperative programming paradigm by introducing their own notion of modules. OO calls them objects (and classes) and lets them encapsulates both data (fields) and procedures (methods) together. SO, in contrast, separates data (records, beans, ...) from code (components, services). However, only OO has programming languages which natively support its paradigm: Smalltalk, C++, Java and all other JVM-compatibles, C# and all other .NET-compatibles, Python etc. SO has no such native language. It only comes into existence on top of procedural languages or OO languages: COM/DCOM (binary, C, C++), CORBA, EJB, Spring, Guice (all Java), ... These SO frameworks clearly suffer from the missing native language support of their concepts. They start using OO classes to represent services and records. This leads to designs where there is a clear distinction between classes that have methods only (services) and those that have fields only (records). Inheritance between services or records is then simulated by inheritance of classes. Technically, its not kept so strictly but in general programmers are adviced to make classes to play only one of the two roles. They use additional, external languages to represent the missing parts: IDL's, XML configurations, Annotations in Java code, or even embedded DSL like in Guice. This is especially needed, but not limited to, since the composition of services is not part of the service code itself. In OO, objects create other objects so there is no need for such facilities but for SO there is because services don't instantiate or configure other services. They establish an inner-platform effect on top of OO (early EJB, CORBA) where the programmer has to write all the code that is needed to "drive" SO. Classes represent only a part of the nature of a service and lots of classes have to be written to form a service together. All that boiler plate is necessary because there is no SO compiler which would do it for the programmer. This is just like some people did it in C for OO when there was no C++. You just pass the record which holds the data of the object as a first parameter to the procedure which is the method. In a OO language this parameter is implicit and the compiler produces all the code that we need for virtual functions etc. For SO, this is clearly missing. Especially the newer frameworks extensively use AOP or introspection to add the missing parts to a OO language. This doesn't bring the necessary language expressiveness but avoids the boiler platform code described in the previous point. Some frameworks use code generation to produce the boiler plate code. Configuration files in XML or annotations in OO code is the source of information for this. Not all of the phenomena that I mentioned above can be attributed to SO but I hope it clearly shows that there is a need for a SO language. Since this paradigm is so popular: why isn't there one? Or maybe there are some academic ones but at least the industry doesn't use one.

• Application Module Extension in Oracle Application R12

  - by Manoj Madhusoodanan

  In this blog I will describe how to Extend Application Module.I will explain this based on my previous blog PL/SQL based EO.  I want to extend FndUserAM to add a procedure to raise a custom business event when the FND_USER has created successfully. Here I am using a custom business event "xxcust.oracle.apps.demo_event". Please find the code used in Business Event. TablePackage Following steps needs to perform. 1) Download all files pertaining to "Entity Object Based on PL/SQL" to JDEV_USER_HOME/myprojects and JDEV_USER_HOME/myclasses.If you want to see the content of source java file decompile it and save it in JDEV_USER_HOME/myprojects. 2) Create XXFndUserAM as follows. 3) Add following method to XXFndUserAMImpl.    import oracle.apps.fnd.framework.OAException;   import oracle.apps.fnd.framework.server.OADBTransactionImpl;   import oracle.apps.fnd.wf.bes.BusinessEvent;   import oracle.apps.fnd.wf.bes.BusinessEventException;    import java.sql.Connection;     public void raiseEvent(String userName) {        String eventName = "xxcust.oracle.apps.demo_event";        String eventKey = userName;        Connection conn = ((OADBTransactionImpl)getOADBTransaction()).getJdbcConnection();         BusinessEvent event = null;         try{             event = new BusinessEvent(eventName, eventKey);             /* Setting Parameters */             event.setStringProperty("USER_NAME",userName);             event.setStringProperty("STATUS","User has created sucessfully");             event.raise(conn);             }             catch (BusinessEventException e) {                 throw new OAException("Exception occured when invoking web service - "+e.getMessage());             }             getOADBTransaction().commit();    } 4) Create a controller which extends from xxcust.oracle.apps.fnd.user.webui.CreateFndUserCO.Call raiseEvent method from new controller. 5) Create substitution for FndUserAM. 6) Migrate following files to $JAVA_TOP. xxcustom.oracle.apps.fnd.user.server.FndUserAMImpl.javaxxcustom.oracle.apps.fnd.user.server.XXFndUserAM.xmlxxcustom.oracle.apps.fnd.user.webui.XXCreateFndUserCO.java 8) Migrate the substitution. 9) Restart the server. 10) Personalize the page /xxcust/oracle/apps/fnd/user/webuiCreateFndUserPG and set the new controller. 11) Verify the substitution has properly applied by clicking About the Page. 12) Access the page and create a user.

• Migrating a WebLogic Domain from a 32 to a 64 bit JVM/Architecture

  - by adejuanc

  Currently on 32 bit OS which presents a physical constraint when trying to allocate memory. By limit, a 32 bit OS, will not be able to allocate more than 3 GB on a Linux environment, or 2 GB for Windows environment (not considering Physical Address Extension (PAE) implementation, which can increase the maximum allocatable memory). When this limit is reached, a migration to a 64 bit architecture is recommended. Below are the steps on how to install a 64 WebLogic Server version, along with a 64 Bit JVM and then how to migrate the domain to this new environment. Weblogic Server Version: WebLogic Server Version: 10.3.4.0 OS: Linux adejuan-cl.cl.oracle.com 2.6.18-194.el5 #1 SMP Mon Jan 01 22:10:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux JVM:java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Oracle JRockit(R) (build R28.1.1-13-139783-1.6.0_22-20101206-0136-linux-x86_64, compiled mode) To create migration template: 1. Execute $<WLS_HOME>/wlserver_10.3/common/bin/config_builder.sh 2. Create Domain Template. 3. Select Domain to migrate. 4. Enter the name of template and other info. Click next. 5. Using Add Button, Select libraries you want to add under lib folder. copy jdbc data sources you would like to have under config/jdbc folder. If you want to have log4j configuration, copy log4j.xml under domain_root folder. 6. Select data base for the domain and click next. 7. Enter Admin Server Name and port numbers. Click next. 8. Enter username and password. Click next. Select No if you don want to add users/groups/roles 9. Click next until reach button create. This will create a jar file that is needed for the next action plan. To install and migrate domain to 64 bit architecture. 1. Install JVM Jrockit R28.1.1.13 on environment. (uncompress zip folder on a known location) 2. Go to JRockit_Home/bin and execute $ java -d64 -jar wls1034_generic.jar 3. When prompt, select JRockit JVM in browse menu, and wait for installation to finish. 4. Go to <WLS_HOME>/wlserver_10.3/common/bin and execute $ ./config.sh 5. Select Create a new Weblogic domain 6. Select Base this domain on an existing template and select browse. 7. Select jar file created on previous action plan. 8. Select Name of domain. Maintain in most cases. 9. Select user name and password. Maintain in most cases. 10. Select Jrockit SDK 1.6.0_22 and click next. 11. Confirm all JMS/JDBC/security configuration. 12. On select Optional Configuration, reconfigure if necessary. 13. Check on Configuration summary for all domain configuration. 14. Click on create, to finish up domain import. Note: Always when installing a 64 bit WLS, it's necessary to install first the 64 JVM and then run the generic installer with the -d64 bit option. If this is not performed, the installation will be the 32 default version. For more information, please refer: http://download.oracle.com/docs/cd/E13188_01/jrockit/docs50/dev_faq.html#pae

• Fresh Ubuntu Install - Grub not loading

  - by Ryan Sharp

  System Ubuntu 12.04 64-bit Windows 7 SP1 Samsung 64GB SSD - OS' Samsung 1TB HDD - Games, /Home, Swap WD 300'ishGB HDD - Backup Okay, so I'm very frustrated, so please excuse me if I miss anything out as my head is clouded by anger and impatience, etc. I'll try me best, though. First of all, I'll explain how I got to my predicament. I finally got my new SSD. I firstly installed Windows, which completed without a hitch. Afterwards, I tried to install Ubuntu, which failed several times due to problems irrelevant to this question, but I mention this to explain my frustrations, sorry. Anyway, I finally installed Ubuntu. However, I chose the 'bootloader' to be installed on the same partition as where I was installing the Ubuntu Root partition, as that was what I believed to be the best choice. It was of my thinking that it was supposed to go on the same partition and on the SSD, which is my OS drive, though with my problem, it apparently was wrong. So I tried to fix it by checking guides and following their directions, but seemed to have messed it up even more. Here is what I receive after I use the fdisk -l command: (I also added explanations for which I used each partition for) Disk /dev/sda: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders, total 125045424 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x324971d1 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 208896 48957439 24374272 7 HPFS/NTFS/exFAT /dev/sda3 48959486 125044735 38042625 5 Extended /dev/sda5 48959488 125044735 38042624 83 Linux sda1 --/ Windows Recovery sda2 --/ Windows 7 sda3/5 --/ Ubuntu root [ / ] Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc0ee6a69 Device Boot Start End Blocks Id System /dev/sdb1 1024208894 1953523711 464657409 5 Extended /dev/sdb3 * 2048 1024206847 512102400 7 HPFS/NTFS/exFAT /dev/sdb5 1024208896 1939851263 457821184 83 Linux /dev/sdb6 1939853312 1953523711 6835200 82 Linux swap / Solaris sdb3 --/ Partition for Steam games, etc. sdb5 --/ Ubuntu Home [ /home ] sdb6 --/ Ubuntu Swap Partition table entries are not in disk order Disk /dev/sdc: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x292eee23 Device Boot Start End Blocks Id System /dev/sdc1 2048 625141759 312569856 7 HPFS/NTFS/exFAT sdc1 --/ Generic backup I also used a Boot Script that other users suggested, so that I can give more details on my partitions and also where Grub is located... ============================= Boot Info Summary: =============================== => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Grub2 (v1.99) is installed in the MBR of /dev/sdb and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos5)/boot/grub on this drive. => Windows is installed in the MBR of /dev/sdc. Now that is weird... Why would Grub2 be installed on both my SSD and HDD? Even weirder is why is Windows on the MBR of my backup hard drive? Nothing I did should have done that... Anyway, here is the entire Output from that script... PASTEBIN So, to summarize what I need: How can I fix my setup so grub loads on startup? How can I clean my partitions to remove unnecessary grubs? What did I do wrong so that I don't do something so daft again? Thank you so much for reading, and I hope you can help me. I've been trying to have a successful setup since Friday, and I'm almost at the point that I'm really tempted to throw my computer out the window due to my frustration.

• what differs a computer scientist/software engineer to regular people who learn programming language and APIs?

  - by Amumu

  In University, we learn and reinvent the wheel a lot to truly learn the programming concepts. For example, we may learn assembly language to understand, what happens inside the box, and how the system operates, when we execute our code. This helps understanding higher level concepts deeper. For example, memory management like in C is just an abstraction of manually managed memory contents and addresses. The problem is, when we're going to work, usually productivity is required more. I could program my own containers, or string class, or date/time (using POSIX with C system call) to do the job, but then, it would take much longer time to use existing STL or Boost library, which abstract all of those thing and very easy to use. This leads to an issue, that a regular person doesn't need to get through all the low level/under the hood stuffs, who learns only one programming language and using language-related APIs. These people may eventually compete with the mainstream graduates from computer science or software engineer and call themselves programmers. At first, I don't think it's valid to call them programmers. I used to think, a real programmer needs to understand the computer deeply (but not at the electronic level). But then I changed my mind. After all, they get the job done and satisfy all the test criteria (logic, performance, security...), and in business environment, who cares if you're an expert and understand how computer works or not. You may get behind the "amateurs" if you spend to much time learning about how things work inside. It is totally valid for those people to call themselves programmers. This makes me confuse. So, after all, programming should be considered an universal skill? Does programming language and concepts matter or the problems we solve matter? For example, many C/C++ vs Java and other high level language, one of the main reason is because C/C++ features performance, as well as accessing low level facility. One of the main reason (in my opinion), is coding in C/C++ seems complex, so people feel good about it (not trolling anyone, just my observation, and my experience as well. Try to google "C hacker syndrome"). While Java on the other hand, made for simplifying programming tasks to help developers concentrate on solving their problems. Based on Java rationale, if the programing language keeps evolve, one day everyone can map their logic directly with natural language. Everyone can program. On that day, maybe real programmers are mathematicians, who could perform most complex logic (including business logic and academic logic) without worrying about installing/configuring compiler, IDEs? What's our job as a computer scientist/software engineer? To solve computer specific problems or to solve problems in general? For example, take a look at this exame: http://cm.baylor.edu/ICPCWiki/attach/Problem%20Resources/2010WorldFinalProblemSet.pdf . The example requires only basic knowledge about the programming language, but focus more on problem solving with the language. In sum, what differs a computer scientist/software engineer to regular people who learn programming language and APIs? A mathematician can be considered a programmer, if he is good enough to use programming language to implement his formula. Can we programmer do this? Probably not for most of us, since we specialize about computer, not math. An electronic engineer, who learns how to use C to program for his devices, can be considered a programmer. If the programming languages keep being simplified, may one day the software engineers, who implements business logic and create softwares, be obsolete? (Not for computer scientist though, since many of the CS topics are scientific, and science won't change, but technology will).
