• Is Oberon really "a better Pascal"?

  - by Maksee

  Reading Niklaus Wirth, one can notice that despite some popularity of Pascal, he is not glad that Oberon (as a "polished" successor of Pascal and Modula) didn't get much popularity. I never did anything in Oberon, but reading the page Oberon For Pascal Developers I really did not like many of the changes as a Delphi/pascal developer, for example forcing the reserved words to be always uppercase making the language case-sensitive getting rid of enumeration types What do you think about Oberon, is it really "a better Pascal" from your point of view?

• Windows Deployment Services

  - by timbrigham

  I have a slightly advanced Windows Deployment Services setup. My router hands out DHCP addresses, including the following config. ip dhcp pool Servers_100 network 192.168.100.0 255.255.255.0 bootfile boot\\x86\\pxelinux.0 next-server 192.168.100.50 default-router 192.168.100.1 dns-server 192.168.100.80 192.168.100.81 This works perfectly for other subnets - I have a couple screens in my pxelinux that allow me to select my various Linux installers or enter the windows preboot environment. For some reason I'm only receiving the default bootfile that opens to the windows preboot environment. Any idea why?

• Change audio output depending on which one is on

  - by pkrish

  I have a PC that is hooked up to my HDTV (via a long hdmi cable) and to a monitor, which is in another room. I have speakers directly plugged to the PC audio out. The PC is next to the monitor and speakers. I am not sure but I think Windows can play sound on only 1 audio device at a time. And I can only set 1 device as the default output. I can get sound on the TV or speaker depending on which device I set to default. But I would have to do this every time I switch between using my TV or my monitor! Is there some way to configure such that sound plays through the TV if the TV is on, else it plays in the speakers? If this is not possible, then the next best alternative would be to get the sound to play on both the devices at the same time. Thanks!

• Camtasia Studio

  - by Andy Morrison

  Have you heard about this tool? This is a capture tool that records your actions as you perform them on your workstation, remote desktop, etc.  It's made by the same company that makes SnagIt, etc. http://www.techsmith.com/camtasia.asp I have used this at several customers to record our install and configurations of BizTalk and more - this can come in very handy to help reduce differences in environments (because you can go back and review exactly what you did in the previous environment) as well as to supplement your installation docs.   The product also includes an editing studio and various media types for export. I haven't been paid to write this - I just think the tool is very nice.

• How do you structure computer science University notes?

  - by Sai Perchard

  I am completing a year of postgraduate study in CS next semester. I am finishing a law degree this year, and I will use this to briefly explain what I mean when I refer to the 'structure' of University notes. My preferred structure for authoring law notes: Word Two columns 0.5cm margins (top, right, bottom, middle, left) Body text (10pt, regular), 3 levels of headings (14/12/10pt, bold), 3 levels of bulleted lists Color A background for cases Color B background for legislation I find that it's crucial to have a good structure from the outset. My key advice to a law student would be to ensure styles allows cases and legislation to be easily identified from supporting text, and not to include too much detail regarding the facts of cases. More than 3 levels of headings is too deep. More than 3 levels of a bulleted list is too deep. In terms of CS, I am interested in similar advice; for example, any strategies that have been successfully employed regarding structure, and general advice regarding note taking. Has latex proved better than Word? Code would presumably need to be stylistically differentiated, and use a monospaced font - perhaps code could be written in TextMate so that it could be copied to retain syntax highlighting? (Are notes even that useful in a CS degree? I am tempted to simply use a textbook. They are crucial in law.) I understand that different people may employ varying techniques and that people will have personal preferences, however I am interested in what these different techniques are. Update Thank you for the responses so far. To clarify, I am not suggesting that the approach should be comparable to that I employ for law. I could have been clearer. The consensus so far seems to be - just learn it. Structure of notes/notes themselves are not generally relevant. This is what I was alluding to when I said I was just tempted to use a textbook. Re the comment that said textbooks are generally useless - I strongly disagree. Sure, perhaps the recommended textbook is useless. But if I'm going to learn a programming language, I will (1) identify what I believe to be the best textbook, and (2) read it. I was unsure if the combination of theory with code meant that lecture notes may be a more efficient way to study for an exam. I imagine that would depend on the subject. A subject specifically on a programming language, reading a textbook and coding would be my preferred approach. But I was unsure if, given a subject containing substantive theory that may not be covered in a single textbook, people may have preferences regarding note taking and structure.

• Web Site Performance and Assembly Versioning – Part 2 Versioning Combined Files Using Subversion

  - by capgpilk

  Ok so it took a while to post this second part. Many apologies, we had a big roll out of a new platform at work and many things had to get sidelined. So this is the second part in a short series of website performance and using versioning to help improve it. Minification and Concatination of JavaScript and CSS Files Versioning Combined Files Using Subversion – this post Versioning Combined Files Using Mercurial – published shortly In the previous post we used AjaxMin to shrink js and css files then concatenated them into one file each which had the file name of site-script.combined.min.js and site-style.combined.min.css. These file names are fine, but you can configure IIS 7 to cache these static files and so lower the amount of data transferred between server and client. This is done by editing the response headers in IIS. 1. In IIS7 Manager, choose the directory where these files are located and select HTTP Response Headers. 2. Check the Expire Web Content and set a time period well into the future. 3. When refreshing the web page, the server will respond with HTTP 304 forcing the browser to retrieve the file from its cache. 4. As can be seen in FireBug, the Cache-Control header has a max age of 31536000 seconds which equates to 365 days.   The server will always send this HTTP 304 message unless the file changes forcing it to send new content. To help force this we can change the file name based on the latest build using the SVN revision number in the filename. So we have lowered data transfer on content that hasn’t changed, but forced it to be sent when you have made a change to the css or js files. Now to get the SVN revision number in to the file name. 1. Import the MSBuildCommunityTasks targets which can be dowloaded from here. 1: <Import Project="$(MSBuildExtensionsPath) 2: \MSBuildCommunityTasks 3: \MSBuild.Community.Tasks.Targets" /> 2. Edit the BeforeBuild target to call out to svn and get the latest revision 1: <SvnVersion LocalPath="$(MSBuildProjectDirectory)" 2: ToolPath="$(ProgramFiles)\VisualSVN Server\bin"> 3: <Output TaskParameter="Revision" PropertyName="Revision" /> 4: </SvnVersion> 3. Set it to update the project AssemblyInfo.cs file for the svn revision. 1: <FileUpdate Files="Properties\AssemblyInfo.cs" 2: Regex="(\d+)\.(\d+)\.(\d+)\.(\d+)" 3: ReplacementText="$1.$2.$3.$(Revision)" /> 4. Now edit the AfterBuild target to get the full dll version. You could combine these two steps and just get the version from svn, I am working on one project that updates the AssemblyInfo file and another project that allows manual editing of the file, but needs that version within the file name; so I just combined the two for this post. 1: <MSBuild.ExtensionPack.Framework.Assembly 2: TaskAction="GetInfo" 3: NetAssembly="$(OutputPath)\mydll.dll"> 4: <Output TaskParameter="OutputItems" ItemName="Info" /> 5: </MSBuild.ExtensionPack.Framework.Assembly> 6: <Message Text="Version: %(Info.AssemblyVersion)" 7: Importance="High" /> 5. Use this Info.AssemblyVersion to write out the combined css and js files as described in the last post. 1: <WriteLinestoFile File="Scripts\site-%(Info.AssemblyVersion).combined.min.js" 2: Lines="@(JSLinesSite)" Overwrite="true" />   In the next post I will cover doing the same, but for a Mercurial repository.

• How to fix Failed to initialize Windows Azure storage emulator error

  - by ybbest

  When you press F5 to start debugging Azure project, you might get the following exception: If you go to the Output windows, you will see the detailed error message below: Windows Azure Tools: Failed to initialize Windows Azure storage emulator. Unable to start Development Storage. Failed to start Development Storage: the SQL Server instance ‘localhost\SQLExpress’ could not be found. Please configure the SQL Server instance for Development Storage using the ‘DSInit’ utility in the Windows Azure SDK. This is because by default, Azure uses the SQLExpress to start Development Storage. To fix this you can do the following: You need to open command prompt, and navigate to C:\Program Files\Windows Azure SDK\v1.4\bin\devstore (depending on your Azure version, the file path is slightly different.) Next, run DSInit /sqlInstance:. (. Means the SQL Server use the default instance, if you have name instance, you need to change. to the name of the SQL Server) After a short while, you should see the following windows showing the configuration succeeds. You can download a batch file here. References: http://msdn.microsoft.com/en-us/library/gg433132.aspx

• Function keys on Dell laptop work double as OEM keys

  - by Factor Mystic

  I'm working with a new Dell Studio 1555, and the F1-F12 keys at the top of the keyboard are dual function with OEM keys such as volume and screen brightness. The problem is, is that the OEM keys are the default, and you have to press the Fn key to get the F- key to work. For example, this means you have to hit Alt+Fn+F4 to close a window, instead of the regular Alt+F4. This is really annoying. Is there a way to reverse the default functions of the F- keys in Windows? Ideally this is possible without some kind of third party hotkey manager.

How do I make --color=auto a default ls argument?

• Persistence problem when installing USB Ubuntu variant using Windows

  - by Derek Redfern

  I'm part of a project called One2One2Go - we're developing a Live USB Ubuntu variant for use in schools in Somerville, MA. We have the project files compiled into an iso, and when installed using the native Ubuntu Startup Disk Creator, the USB works fine. When installed using a tool on a Windows machine (LiLi at linuxliveusb.com or liveusb-creator at fedorahosted.org/liveusb-creator), the USB works, but does not have persistence. This happens even if the creator is specifically set to allocate an area for persistent files. When comparing files on sticks created in Windows or Ubuntu, the one file that is different is syslinux/syslinux.cfg. I have printed the contents of the file below: Installed on Windows: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 Installed on Ubuntu: DEFAULT nomodset LABEL debug menu label ^debug kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper xforcevesa initrd=/casper/initrd.gz -- LABEL nomodset menu label ^nomodset kernel /casper/vmlinuz append noprompt cdrom-detect/try-usb=true persistent boot=casper quiet splash nomodset initrd=/casper/initrd.gz -- LABEL memtest menu label ^Memory test kernel /install/memtest append - LABEL hd menu label ^Boot from first hard disk localboot 0x80 append - PROMPT 0 TIMEOUT 1 For troubleshooting reasons, I changed the Windows-created syslinux.cfg to match the one created by Ubuntu and persistence worked on it. I think the problem is that on the stick created by Windows, there is no "persistent" flag, but I don't know why. Is this a problem with our disk image or with the creator? How would I go about fixing this problem? Thanks in advance for your help. Derek Redfern

  With JDeveloper 11gR2 you can now create database based web services using JAX-WS Provider. The key differences between this and the already existing PL/SQL Web Services support is:Based on JAX-WS ProviderSupports SQL Queries for creating Web ServicesSupports Table CRUD OperationsThis is present as a new option in the New Gallery under 'Web Services'When you invoke the New Gallery option, it present you with three options to choose from:In this entry I will explain the options of creating service based on SQL queries and Table CRUD operations.SQL Query based Service When you select this option, on 'Next' page it asks you for the DB Conn details. You can also choose if you want SOAP 1.1 or 1.2 format. For this example, I will proceed with SOAP 1.1, the default option.On the Next page, you can give the SQL query. The wizard support Bind Variables, so you can parametrize your queries. Give "?" as a input parameter you want to give at runtime, and the "Bind Variables" button will get enabled. Here you can specify the name and type of the variable.Finish the wizard. Now you can test your service in Analyzer:See that the bind variable specified comes as a input parameter in the Analyzer Input Form:CRUD OperationsFor this, At Step 2 of Wizard, select the radio button "Generate Table CRUD Service Provider"At the next step, select the DB Connection and the table for which you want to generate the default set of operations:Finish the Wizard. Now, run the service in Analyzer for a quick check.See that all the basic operations are exposed:

• Creating a dynamically updateable website using Adobe Flash CS6 [closed]

  - by Sidd

  I need some help finding the appropriate tutorials for what I need. I have tried looking hard with no avail. I have Adobe Flash CS6, and I want to make a website using that software. I want the content to be uploaded onto a server so that the flash program can just fetch the information from the server and dynamically update the website itself, instead of editing the content on the flash website and reuploading the whole flash file (as I have done before). I also want the ability to have a guestbook and a contact form. Also, if possible, I wanted an ability to add tabs to the navigation bar dynamically instead of having to edit the flash file. Can anyone point be to a good tutorial which can help me with this? I have tried looking, and most of the results I get are completely useless to me.

• How to boot windows 8 in a dual boot along with windows 7?

  - by GoldDove

  I have installed a WIndows 8 evaluation about a week ago. Usually, it asks me every time I turn on my computer whether to boot into windows 8 or windows 7. The default was windows 8 after 30 seconds. I changed that just yesterday to be default windows 7 after 5 seconds. And after I changed the setting, I went ahead and went into windows 8 and did my work. Today, when I turned on my computer, it is failing to ask me which one to boot it in. It simply boots directly into Windows 7. Is there any reason for this? Can I no longer boot into Windows 8?

• Importance of scripting engine at Cocos2d Game Engine

  Each Game Engine is different and solves different problems in different ways, so the engine design does vary greatly from engine to engine (even though a lot of principles are shared from engine to engine). Cocos2D is a great product on it’s own, but it doesn’t expose engine functionality to a scripting Language like Lua, JavaScript etc. My Question: How much important to integrate a Scripting Engine at Cocos2d?

I am running about 20 game servers that bind to a UDP port, then bind to a TCP port 1 above the UDP port. Suddenly, a day ago, new TCP binds stopped functioning. Now, I have confirmed that other applications cannot listen on most ports. For example, I have a java program that I made a copy of, and tried the following ports: 33001, 23789, 89... completely random ports. As far as the applications already that have TCP bindings, such as HTTP and MySQL, only port 8080 was one port I discovered could work, and only for Apache. If applications would leave their default port they could not bind, however they returned to normal when the port was default. I've checked for listening applications through netstat and curports, also checked for any connections on these ports, and they're completely free.

• User cannot book a room resource in Exchange 2010

  - by bakesale

  Im having a problem with a specific user not being able to book a room resource. No error message is generated at all. The user attempts to add the room as a meeting resource and it simply doesnt register with the resources calendar. I have tested the resource with other accounts and other rooms for this user but it is only this room that is having issues for this user. This Exchange server was migrated from 2007 to 2010. All rooms except for the problem room were created back on Exchange 2007. This new room was created with Exchange 2010. Maybe this clue has something to do with the problem? This is a paste of the mailboxes folder permissions [PS] C:\Windows\system32Get-MailboxFolderPermission -identity room125:\calendar RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Default AccessRights : {Author} Identity : Default IsValid : True RunspaceId : 448ab44a-4c2a-4403-b46c-fce1106c0823 FolderName : Calendar User : Anonymous AccessRights : {None} Identity : Anonymous IsValid : True

• Mount drives at `/drivename` from nautilus

  - by Anwar Shah

  I want to mount my other drives (mostly ntfs and fat) on /drivename by clicking on the drive icon in the nautilus side pane, where "drivename" refers to the label of the drive. By default nautilus (actually the udisks program) mounts drives in /media/ folder with drive name. How can I achieve this?. Note: Please do not suggest doing this by editing /etc/fstab file. I want this feature in nautilus and after clicking the drive should also be seen in the side pane. (should not be hidden). Edit: Seems to be some have misunderstood this. I don't want to mount in / but as /Main, where "Main" is the label of my ntfs partition. To make it clear, suppose I have two partitions named as "Work" and "Main". I want them to mount at /Work and /Main respectively, when clicked on their icon in nautilus

• C# Domain-Driven Design Sample Released

  - by Artur Trosin

  In the post I want to declare that NDDD Sample application(s) is released and share the work with you. You can access it here: http://code.google.com/p/ndddsample. NDDDSample from functionality perspective matches DDDSample 1.1.0 which is based Java and on joint effort by Eric Evans' company Domain Language and the Swedish software consulting company Citerus. But because NDDDSample is based on .NET technologies those two implementations could not be matched directly. However concepts, practices, values, patterns, especially DDD, are cross-language and cross-platform :). Implementation of .NET version of the application was an interesting journey because now as .NET developer I better understand the differences positive and negative between these two platforms. Even there are those differences they can be overtaken, in many cases it was not so hard to match a java libs\framework with .NET during the implementation. Here is a list of technology stack: 1. .net 3.5 - framework 2. VS.NET 2008 - IDE 3. ASP.NET MVC2.0 - for administration and tracking UI 4. WCF - communication mechanism 5. NHibernate - ORM 6. Rhino Commons - Nhibernate session management, base classes for in memory unit tests 7. SqlLite - database 8. Windsor - inversion of control container 9. Windsor WCF facility - for better integration with NHibernate 10. MvcContrib - and in particular its Castle WindsorControllerFactory in order to enable IoC for controllers 11. WPF - for incident logging application 12. Moq - mocking lib used for unit tests 13. NUnit - unit testing framework 14. Log4net - logging framework 15. Cloud based on Azure SDK These are not the latest technologies, tools and libs for the moment but if there are someone thinks that it would be useful to migrate the sample to latest current technologies and versions please comment. Cloud version of the application is based on Azure emulated environment provided by the SDK, so it hasn't been tested on ‘real' Azure scenario (we just do not have access to it). Thanks to participants, Eugen Gorgan who was involved directly in development, Ruslan Rusu and Victor Lungu spend their free time to discuss .NET specific decisions, Eugen Navitaniuc helped with Java related questions. Also, big thank to Cornel Cretu, he designed a nice logo and helped with some browser incompatibility issues. Any review and feedback are welcome! Thank you, Artur Trosin

• Web Site Development Software for VirtualBox Ubuntu 11.04

  - by Paul Sonier

  I'm doing some development of a website on a VirtualBox guest running Ubuntu 11.04 (host is running Windows, but I want to do the web development in a Linux environment). My development languages are primarily PHP and Javascript (using Apache and node.js). The question is this: is there a good IDE for work under these conditions that can handle running virtualized? I tried Eclipse, and was not particularly thrilled with the performance; I'm wondering if there's some other way to do this than to do all my text editing in emacs.
