  • Opengl glVertexAttrib4fv doesn't work?

    - by Naor
    This is my vertex shader: static const GLchar * vertex_shader_source[] = { "#version 430 core \n" "layout (location = 0) in vec4 offset; \n" "void main(void) \n" "{ \n" " const vec4 vertices[3] = vec4[3](vec4( 0.25, -0.25, 0.5, 1.0),\n" " vec4(-0.25, -0.25, 0.5, 1.0), \n" " vec4( 0.25, 0.25, 0.5, 1.0)); \n" " gl_Position = vertices[gl_VertexID] + offset; \n" "} \n" }; and this is what im trying to do: glUseProgram(rendering_program); GLfloat attrib[] = { (float)sin(currentTime) * 0.5f, (float)cos(currentTime) * 0.6f, 0.0f, 0.0f }; glVertexAttrib4fv(0, attrib); glDrawArrays(GL_TRIANGLES, 0, 3); currentTime - The number in seconds since the program has started. Expected result - Triangle moving around the window. Its from the SuperBible book (sixth edition), this is the full code:http://pastebin.com/xA3eCKz1 The triangle should move across the screen but it doesn't.

  • Dealing with a fundamental design flaw when you're new to the project

    - by Matt Phillips
    I've just started working on an open source project with around 30 developers in it. I'm working on fixing some of the bugs as a way to get into the "loop" and become a regular committer to the project. The problem is I think I've uncovered a fundamental design flaw that's causing one of the bugs I'm working on. But I feel like if I blast this on the mailing list I'm going to come off as arrogant, and some of the discussions I've had about the issue are butting heads with some of the people. How should I go about this?

  • what, why, when, should I learn computer science?

    - by dramasea
    I'm 16 years old and really an enthusiast on web programming. I know (X)HTML, css, javascript and php. And i heard about computer science. Below are my question: What is computer science? Should a web programmer learn computer science? If the answer of question 2 is yes, then what programming language(s) should I learn before I get into computer science (I saw the video of 'Introduction to computer science' which is one of the MIT opencourse and it started to use python without teaching you from scratch.) Can I learn computer science now? (Without a university degree, I can watch open courseware.)

  • [WP7] How to decompile WP7 assemblies

    - by Benjamin Roux
    The other day I wanted to check the source code of the ScrollViewer of WP7. I started Reflector (profit while its still free) and I opened the System.Windows.dll assembly located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0\Profile\WindowsPhone. When Reflector did the job I was surprised to see that all the methods/properties were empty ! After some investigations, I found out that these assemblys are used by Visual Studio for the Intelisense (among others) and so, for develoment. The thing is I still couldn’t check the ScrollViewer’s source code. Finally after new investigations, I discovered a link on the XDA forum which provide the WP7 emulator dump. I downloaded it and decompiled the GAC_System.Windows_v2_0_5_0_cneutral_1.dll assembly located this time at /SYS/SILVERLIGHT. Et voila, the ScrollViewer’s source code is available. Hope this helps.

  • How can I move from Java and ColdFusion to Ruby on Rails?

    - by Ciaran Archer
    Currently I work with ColdFusion 9+ and some Java in a Windows environment. Prior to ColdFusion, my background was in Java and JSP. I'm considering a move towards Ruby on Rails, as I think it would be a real challenge, keep things fresh, and provide more job opportunities. In order to get into it, I started to build my personal website in Rails 3.0. But what else can I do to make this transition from what I know now to Ruby and Rails? Are there specific or idiomatic aspects of Ruby or Rails I should keep in mind when switching over from a ColdFusion and Java mindset?

  • What You Said: The Technology You’re Most Thankful For

    - by Jason Fitzpatrick
    Earlier this week we asked you to share the technology you were most thankful for–big or small, old or new–and you responded. Read on to see the tech your fellow readers are thankful to have. Many readers were thankful for the Internet as an entire technological advance. Lee writes: I’d probably have to say the Internet in general, because that has essentially inspired most most of the features in modern technology. Plus, I wouldn’t know nearly as much about tech now if I didn’t have access to the Internet. Jim is especially thankful for the Internet: The Internet. The information I’ve found and people I’ve met, (including my wife), have been life changing. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

  • Certificate error with Web Platform Installer

    - by findleyd
     A friend of mine was having an issue getting the Web Platform Installer to work on his Windows Server 2008 R2 box. He said there was some sort of cert error and asked me to try https://go.microsoft.com/fwlink/?LinkId=158722 on my local machine to see if I got the cert error.  I tried it and I did get a cert error on Windows 7 64bit. I happened to notice that that url simply redirects to https://www.microsoft.com/web/webpi/2.0/WebProductList.xml . Out of curiosity I dropped to a command line and tried to run .\WebPlatformInstaller.exe /? to see if there were any command line options. It gave an error that said invalid URI. So we tried running it with the product list url like: "WebPlatformInstaller.exe https://www.microsoft.com/web/webpi/2.0/WebProductList.xml" . This seems to get around the expired cert that is on go.microsoft.com.  Here's a screen shot of the error:

  • Connect Microsoft Excel To SQL Azure Database

    A number of people have found my post about getting started with SQL Azure pretty useful. But, it's all worthless if it doesn't add up to user value. Database are like potential energy in physics-it's a promise that something could be put in motion. Users actually making decisions based on analysis is analogous to kinetic energy in physics. It's the fulfillment of the promise of potential energy. So what does this have to with Office 2010? In Excel 2010 we made it truly easy to connect to a SQL Azure...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Introducing Microsoft SQL Server 2008 R2 - Business Intelligence Samples

    - by smisner
    On April 14, 2010, Microsoft Press (blog | twitter) released my latest book, co-authored with Ross Mistry (twitter), as a free ebook download - Introducing Microsoft SQL Server 2008 R2. As the title implies, this ebook is an introduction to the latest SQL Server release. Although you'll find a comprehensive review of the product's features in this book, you will not find the step-by-step details that are typical in my other books. For those readers who are interested in a more interactive learning experience, I have created two samples file for download: IntroSQLServer2008R2Samples project Sales Analysis workbook Here's a recap of the business intelligence chapters and the samples I used to generate the screen shots by chapter: Chapter 6: Scalable Data Warehousing covers a new edition of SQL Server, Parallel Data Warehouse. Understandably, Microsoft did not ship me the software and hardware to set up my own Parallel Data Warehouse environment for testing purposes and consequently you won't see any screenshots in this chapter. I received a lot of information and a lot of help from the product team during the development of this chapter to ensure its technical accuracy. Chapter 7: Master Data Services is a new component in SQL Server. After you install Master Data Services (MDS), which is a separate installation from SQL Server although it's found on the same media, you can install sample models to explore (which is what I did to create screenshots for the book). To do this, you deploying packages found at \Program Files\Microsoft SQL Server\Master Data Services\Samples\Packages. You will first need to use the Configuration Manager (in the Microsoft SQL Server 2008 R2\Master Data Services program group) to create a database and a Web application for MDS. Then when you launch the application, you'll see a Getting Started page which has a Deploy Sample Data link that you can use to deploy any of the sample packages. Chapter 8: Complex Event Processing is an introduction to another new component, StreamInsight. This topic was way too large to cover in-depth in a single chapter, so I focused on information such as architecture, development models, and an overview of the key sections of code you'll need to develop for your own applications. StreamInsight is an engine that operates on data in-flight and as such has no user interface that I could include in the book as screenshots. The November CTP version of SQL Server 2008 R2 included code samples as part of the installation, but these are not the official samples that will eventually be available in Codeplex. At the time of this writing, the samples are not yet published. Chapter 9: Reporting Services Enhancements provides an overview of all the changes to Reporting Services in SQL Server 2008 R2, and there are many! In previous posts, I shared more details than you'll find in the book about new functions (Lookup, MultiLookup, and LookupSet), properties for page numbering, and the new global variable RenderFormat. I will confess that I didn't use actual data in the book for my discussion on the Lookup functions, but I did create real reports for the blog posts and will upload those separately. For the other screenshots and examples in the book, I have created the IntroSQLServer2008R2Samples project for you to download. To preview these reports in Business Intelligence Development Studio, you must have the AdventureWorksDW2008R2 database installed, and you must download and install SQL Server 2008 R2. For the map report, you must execute the PopulationData.sql script that I included in the samples file to add a table to the AdventureWorksDW2008R2 database. The IntroSQLServer2008R2Samples project includes the following files: 01_AggregateOfAggregates.rdl to illustrate the use of embedded aggregate functions 02_RenderFormatAndPaging.rdl to illustrate the use of page break properties (Disabled, ResetPageNumber), the PageName property, and the RenderFormat global variable 03_DataSynchronization.rdl to illustrate the use of the DomainScope property 04_TextboxOrientation.rdl to illustrate the use of the WritingMode property 05_DataBar.rdl 06_Sparklines.rdl 07_Indicators.rdl 08_Map.rdl to illustrate a simple analytical map that uses color to show population counts by state PopulationData.sql to provide the data necessary for the map report Chapter 10: Self-Service Analysis with PowerPivot introduces two new components to the Microsoft BI stack, PowerPivot for Excel and PowerPivot for SharePoint, which you can learn more about at the PowerPivot site. To produce the screenshots for this chapter, I created the Sales Analysis workbook which you can download (although you must have Excel 2010 and the PowerPivot for Excel add-in installed to explore it fully). It's a rather simple workbook because space in the book did not permit a complete exploration of all the wonderful things you can do with PowerPivot. I used a tutorial that was available with the CTP version as a basis for the report so it might look familiar if you've already started learning about PowerPivot. In future posts, I'll continue exploring the new features in greater detail. If there's any special requests, please let me know!

    I have taken my major as computer science and Engineering and I am really confused at this moment. My first course was about learning C and C++ and I learned the basics of those. Now I am really confused what to do next. Some says I should practice algorithms and do contests in ACM-ICPC for now. Others tell me to start software development. But As I started digging its really a vast topic and there are many aspects of these, like web design, web-development, iOS-development, android... etc many things. And I am really confused about what should I do just now. Any advice for me to start with?

  • Testing Mobile Websites with Adobe Shadow

    - by dwahlin
    It’s no surprise that mobile development is all the rage these days. With all of the new mobile devices being released nearly every day the ability for developers to deliver mobile solutions is more important than ever. Nearly every developer or company I’ve talked to recently about mobile development in training classes, at conferences, and on consulting projects says that they need to find a solution to get existing websites into the mobile space. Although there are several different frameworks out there that can be used such as jQuery Mobile, Sencha Touch, jQTouch, and others, how do you test how your site renders on iOS, Android, Blackberry, Windows Phone, and the variety of mobile form factors out there? Although there are different virtual solutions that can be used including Electric Plum for iOS, emulators, browser plugins for resizing the laptop/desktop browser, and more, at some point you need to test on as many physical devices as possible. This can be extremely challenging and quite time consuming though especially when you consider that you have to manually enter URLs into devices and click links on each one to drill-down into sites. Adobe Labs just released a product called Adobe Shadow (thanks to Kurt Sprinzl for letting me know about it) that significantly simplifies testing sites on physical devices, debugging problems you find, and even making live modifications to HTML and CSS content while viewing a site on the device to see how rendering changes. You can view a page in your laptop/desktop browser and have it automatically pushed to all of your devices without actually touching the device (a huge time saver). See a problem with a device? Locate it using the free Chrome extension, pull up inspection tools (based on the Chrome Developer tools) and make live changes through Chrome that appear on the respective device so that it’s easy to identify how problems can be resolved. I’ve been using Adobe Shadow and am very impressed with the amount of time saved and the different features that it offers. In the rest of the post I’ll walk through how to get it installed, get it started, and use it to view and debug pages.   Getting Adobe Shadow Installed The following steps can be used to get Adobe Shadow installed: 1. Download and install Adobe Shadow on your laptop/desktop 2. Install the Adobe Shadow extension for Chrome 3. Install the Adobe Shadow app on all of your devices (you can find it in various app stores) 4. Connect your devices to Wifi. Make sure they’re on the same network that your laptop/desktop machine is on   Getting Adobe Shadow Started Once Adobe Shadow is installed, you’ll need to get it running on your laptop/desktop and on all your mobile devices. The following steps walk through that process: 1. Start the Adobe Shadow application on your laptop/desktop 2. Start the Adobe Shadow app on each of your mobile devices 3. Locate the laptop/desktop name in the list that’s shown on each mobile device: 4. Select the laptop/desktop name and a passcode will be shown: 5. Open the Adobe Shadow Chrome extension on the laptop/desktop and enter the passcode for the given device: Using Adobe Shadow to View and Modify Pages Once Adobe Shadow is up and running on your laptop/desktop and on all of your mobile devices you can navigate to a page in Chrome on the laptop/desktop and it will automatically be pushed out to all connected mobile devices. If you have 5 mobile devices setup they’ll all navigate to the page displayed in Chrome (pretty awesome!). This makes it super easy to see how a given page looks on your iPad, Android device, etc. without having to touch the device itself. If you find a problem with a page on a device you can select the device in the Chrome Adobe Shadow extension on your laptop/desktop and select the remote inspector icon (it’s the < > icon): This will pull up the Adobe Shadow remote debugging window which contains the standard Chrome Developer tool tabs such as Elements, Resources, Network, etc. Click on the Elements tab to see the HTML rendered for the target device and then drill into the respective HTML content, CSS styles, etc. As HTML elements are selected in the Adobe Shadow debugging tool they’ll be highlighted on the device itself just like they would if you were debugging a page directly in Chrome with the developer tools. Here’s an example from my Android device that shows how the page looks on the device as I select different HTML elements on the laptop/desktop: Conclusion I’m really impressed with what I’ve to this point from Adobe Shadow. Controlling pages that display on devices directly from my laptop/desktop is a big time saver and the ability to remotely see changes made through the Chrome Developer Tools (on my laptop/desktop) really pushes the tool over the top. If you’re developing mobile applications it’s definitely something to check out. It’s currently free to download and use. For additional details check out the video below:

  • "Virtual Machine Manager" and "Virtual Machine Server" setup manual

    - by urtihu
    Is there a manual available that covers the proper setup of a "Virtual Machine Server" with no GUI with an Ubuntu Workstation with a GUI and "Virtual Machine Manager" installed? Both are 12.04 version. I get the following error message: unable to connect to libvirt Verify that -The libvirt-bin package is installed -The libvirt daemon has been started -you are a member of the libvirtd group the package is installed for some reason starting the daemon seems to crash libvirtd start info: libvirt version 0.9.8 error: virExecWithHook:328 : cannot find 'pm-is-supported' in path: No such file or directory also qemucapsInit:856: Failed to get host power management capabilities So I guess I did not set the server up correctly. All manuals I found do not mention "Virtual Machine Manager". I only chose the packages to connect with SSH remotely and the "Virtual Machine Server" for the server installation. So I would like to find a manual that covers this combo or then covered only GUI machines that have both on the same machine, which will not really help with system performance as a hypervisor.

    This is the fourth post in my series about Personal Technology Tips and Tricks, and I knew exactly what I wanted to write about.  But at first I was conflicted.   Is online learning really a personal tip?  Is it really a trick that no one knows?  However, I have decided to stick with my original idea because online learning is everywhere.  It’s a trick that we can’t – and shouldn’t – overlook.  Here are ten of my ideas about how we should be taking advantage of online learning. 1) Get ahead in the work place.  We all know that a good way to become better at your job, and to become more competitive for promotions and raises.  Many people overlook online learning as a way to get job training, though, thinking it is a path for people still seeking their high school or college diplomas.  But take a look at what companies like Pluralsight offer, and you might be pleasantly surprised. 2) Flexibility.  Some of us remember the heady days of college with nostalgia, others remember it with loathing.  A lot of bad memories come from remembering the strict scheduling and deadlines of college.  But with online learning, the classes fit into your free time – you don’t have to schedule your life around classes.  Even better, there are usually no homework or test deadlines, only one final deadline where all work must be completed.  This allows students to work at their own pace – my next point. 3) Learn at your own pace.  One thing traditional classes suffer from is that they are highly structured.  If you work more quickly than the rest of the class, or especially if you work more slowly, traditional classes do not work for you.  Online courses let you move as quickly or as slowly as you find necessary. 4) Fill gaps in your knowledge.  I’m sure I am not the only one who has thought to myself “I would love to take a course on X, Y, or Z.”  The problem is that it can be very hard to find the perfect class that teaches exactly what you’re interested in, at a time and a price that’s right.  But online courses are far easier to tailor exactly to your tastes. 5) Fits into your schedule.  Even harder to find than a class you’re interested in is one that fits into your schedule.  If you hold down a job – even a part time job – you know it’s next to impossible to find class times that work for you.  Online classes can be taken anytime, anywhere.  On your lunch break, in your car, or in your pajamas at the end of the day. 6) Student centered.  Online learning has to stay competitive.  There are hundreds, even thousands of options for students, and every provider has to find a way to lure in students and provide them with a good education.  The best kind of online classes know that they need to provide great classes, flexible scheduling, and high quality to attract students – and the student benefit from this kind of attention. 7) You can save money.  The average cost for a college diploma in the US is over $20,000.  I don’t know about you, but that is not the kind of money I just have lying around for a rainy day.  Sometimes I think I’d love to go back to school, but not for that price tag.  Online courses are much, much more affordable.  And even better, you can pick and choose what courses you’d like to take, and avoid all the “electives” in college. 8) Get access to the best minds in the business.  One of the perks of being the best in your field is that you are one person who knows the most about something.  If students are lucky, you will choose to share that knowledge with them on a college campus.  For the hundreds of other students who don’t live in your area and don’t attend your school, they are out of luck.  But luckily for them, more and more online courses is attracting the best minds in the business, and if you enroll online, you can take advantage of these minds, too. 9) Save your time.  Getting a four year degree is a great decision, and I encourage everyone to pursue their Bachelor’s – and beyond.  But if you have already tried to go to school, or already have a degree but are thinking of switching fields, four years of your life is a long time to go back and redo things.  Getting your online degree will save you time by allowing you to work at your own pace, set your own schedule, and take only the classes you’re interested in. 10) Variety of degrees and programs.  If you’re not sure what you’re interested in, or if you only need a few classes here and there to finish a program, online classes are perfect for you.  You can pick and choose what you’d like, and sample a wide variety without spending too much money. I hope I’ve outlined for everyone just a few ways that they could benefit from online learning.  If you’re still unconvinced, just check out a few of my other articles that expand more on these topics.
