• Creating new games on Android and/or iPhone

  - by James Clifton

  I have a succesfull facebook poker game that is running very nicely, now some people have asked if I can port this to other platforms - mainly mobile devices (and I have been asked to make a tablet version, do I really need a seperate version?) I am currently a PHP programmer (and game designer) and I simply dont' have the time to learn Android and other languages - so I have decided to pay third parties to program them (if viable). The information I need to know is what programming language is needed for the following four devices - Android mobile phone, iPhone, iPad and tablets? Can they all run off a central sql database? If they can't then i'm not interested :( Do any of these run FLASH? Have I covered all my main bases here? For example if a person programs for a ANDROID mobile phone is that to much differant to an ANDROID tablet? They will have slightly differant graphics (because the tablet has a greater screen area might as well use it) but do they need to be started from scratch? Same goes for iPhone/iPad, do they really need to be programmed differantly if the only differance is the graphics?

• Internet Explorer 9 is coming Monday to a web near you

  - by brian_ritchie

  Internet Explorer 9 is finally here...well almost.  Microsoft is releasing their new browser on March 14, 2011. IE9 has a number of improvements, including: Faster, Faster, Faster.  Did I mention it is faster?   With the new browsers coming out from Mozilla, Google, and Microsoft, there have been a flood of speed test coverage.  Chrome has long held the javascript speed crown.  But according to Steven J. Vaughan-Nichols over at ZDNET..."for the moment at least IE9 is actually the fastest browser I’ve tested to date."  He came to this revelation after figuring out that the 32-bit version of IE9 has the new Chakra JIT (the 64-bit version doesn't).  It also has a DirectX-based rendering engine so it can do cool tricks once reserved for desktop applications. Windows 7 Desktop Integration.  Read my post for more details.  Unfortantely, they didn't integrate my ideas...at least not yet :) Hot new UI.  Ok, they "borrowed" some ideas from Chrome...but that is the best form of flattery. Standards Compliance.  A real focus on HTML5 and CSS3.  Definite goodness for developers. So, go get yourself some IE9 on Monday and enjoy!

• Google Chrome on Ubuntu 12.04 not rendering webpages correctly

  - by sumit_gt

  I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem? PS: here's the output of lshw -c video: *-display description: VGA compatible controller product: Madison [Radeon HD 5000M Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=fglrx_pci latency=0 resources: irq:46 memory:e0000000-efffffff memory:f0020000-f003ffff ioport:d000(size=256) memory:f0000000-f001ffff Here's the output of lspci -nn: output of lspci -nn

• suggestions for lonewolf dev setup

  - by d33j

  I'm looking for some suggestions for a better development setup. Background: I'm a crusty old software engineer (mostly java of late) and I have around 50 - 100 incomplete java projects scattered everywhere, usb keys, HDDs, and spanning across 5 or 6 computers etc, which have been put on hold for a few years (ie: family). I have no version control at home. I've been using IntelliJ for around 10 years, so that's the only constant. I'm thinking of nominating one machine as a headless server to put all my projects on, maybe a ubuntu box, that way It won't matter which device I'm on, all my projects can be accessed (and I don't have to waste time actually looking for them). I don't need to access code over the net. These are my own 'happy place' projects so I only work on them when I'm at home, however I can see the benefit of the tasking app being online, that way if I think of something while on public transport lets say, I can add it then & there, but it's not a requirement. I can wait until I get home to create tasks. Summary: So I need some sort of version control so I can rollback mistakes, and some sort of simple tasking software where I can assign tasks for myself later on when I get time. I use Subversion, Sonar, Jira and Crucible at work but I think it's a little bit of an overkill for me though. What do you suggest?

• OpenGL doesn't draw (3.3+) [on hold]

  - by Dhiego Magalhães

  Brief: I've been following this tutorial about OpenGL for 2 days, and I still can't have a triangle drawn, so I'm asking for help here. The tutorial is turned to OpenGL version 3.3 programing, using vertex arrays, buffers, etc. The libraries are: GLFW3 and GLEW, and I setted them by myself. The screen keeps black all the time. Full code: link here (It's just like a Hello World opengl program) Further Details: I get no errors at all. I downloaded a software to test my video card, and it supports OpenGL 4.1+ Standard OpenGL code for drawing (from earlier version) such as this one works normally. I'm using Microsoft Visual Studio 10.0 I presume all the OpenGL implementation was dune right: I added Additional Dependences to the linker as glew32.lib, opengl32.lib, glfw3.lib. The glew.dll was placed at SysWOW64 - because I'm running window 64bits, and glew is 32. Notes: I've been working hard to find out what this is, but I can't find. I would appreciate if anyone could test this code for me, so I can know if I implemented something wrong, and that its not my code.

• LiveCD/USB boot issues with Ubuntu 12.04 on blank drive

  - by Richek

  Not sure how common this issue is, or even how badly I may be missing something simple, but I am a first time usuer having some serious problems. Some background: old HDD running Windows 7 developed too many bad sectors and is bricked. I'm attempting to install Ubuntu 12.04 on a fresh 1TB drive by booting from a liveCD USB flash drive. I've not been able to get past the initial menu screen, however, as the process stalls out shortly after selecting an option (both boot from drive and install to drive). I've tried multiple USB drives as well as CDs, modified the boot order, flashed BIOS, and even tried booting with only the flash drive and the keyboard connected with the same results.Typically what I observe is that the OS begins what I think is compliling, listing drivers and components before freezing on one. When the keyboard is plugged in, its the keyboard driver, before I flashed BIOS, it was a BIOS related item, now its an unknown entry. The computer seems to be reading the drive (idicated by USB light flashing or CD drive reving) for roughly 10 minutes with no progress, followed by the drives going quiet. Some spec info: Motherboard: ASUS P5Q Pro, BIOS version 2102 (latest version), Intel chipset CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz help would be appriciated!

• Does IE have more strict Javascript parsing than Chrome?

  - by Clay Shannon

  This is not meant to start a religio-technical browser war - I still prefer Chrome, at least for now, but: Because of a perhaps Chrome-related problem with my web page (see https://code.google.com/p/chromium/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Pri%20M%20Iteration%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified&groupby=&sort=&id=161473), I temporarily switched to IE (10) to see if it would also view the time value as invalid. However, I didn't even get to that point - IE stopped me in my tracks before I could get there; but I found that IE was right - it is more particular/precise in validating my code. For example, I got this from IE: SCRIPT5007: The value of the property '$' is null or undefined, not a Function object ...which was referring to this: <script src="/CommonLogin/Scripts/jquery-1.9.1.min.js" type="text/javascript"></script> <script type="text/javascript"> // body sometimes becomes white???? with jquery 1.6.1 $("body").css("background-color", "#405DA7"); < This line is highlighted as the culprit: $("body").css("background-color", "#405DA7"); jQuery is referenced right above it - so why did it consider "$" to be undefined, especially when Chrome had no problem with it...ah! I looked at that location (/CommonLogin/Scripts/) and saw that, sure enough, the version of jQuery there was actually jquery-1.6.2.min.js. I added the updated jQuery file (1.9.1) and it got past this. So now the question is: why does Chrome ignore this? Does it download the referenced version from its own CDN if it can't find it in the place you specify? IE did flag other errs after that, too; so I'm thinking perhaps IE is better at catching lurking problems than, at least, Chrome is. Haven't tested Firefox diesbzg yet.

• So now Google has said no to old browsers when can the rest of us follow suit?

  - by Richard

  Google recently announced that they will no longer support older browsers on Aug 1st: http://www.bbc.co.uk/news/technology-13639875 http://gmailblog.blogspot.com/2011/06/our-plans-to-support-modern-browsers.html For this reason, soon Google Apps will only support modern browsers. Beginning August 1st, we’ll support the current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting the update and stop supporting the third-oldest version. There is nothing worse than looking at the patching of code that takes place to support older browsers. If we could all move towards a standards only web (I'm looking at you IE9) then surely we could spend more time programming good web apps and less trying to make them run equally on terrible non standards compliant older browsers. So when can the rest of us expect to be able to tell our clients that we no longer support older browsers? Because it seems that large corporates will continue to run older browsers and even if google chrome frame can be installed without admin privileges (it's coming soon, currently in beta) we can't expect all users to be motivated to do this. I appreciate any thoughts.

• D3DXMatrixDecompose gives different quaternion than D3DXQuaternionRotationMatrix

  - by Fraser

  In trying to solve this problem, I tracked down the problem to the conversion of the rotation matrix to quaternion. In particular, consider the following matrix: -0.02099178 0.9997436 -0.008475631 0 0.995325 0.02009799 -0.09446743 0 0.09427284 0.01041905 0.9954919 0 0 0 0 1 SlimDX.Quaternion.RotationMatrix (which calls D3DXQuaternionRotationMatrix gives a different answer than SlimDX.Matrix.Decompose (which uses D3DXMatrixDecompose). The answers they give (after being normalized) are: X Y Z W Quaternion.RotationMatrix -0.05244324 0.05137424 0.002209336 0.9972991 Matrix.Decompose 0.6989997 0.7135442 -0.03674842 -0.03006023 Which are totally different (note the signs of X, Z, and W are different). Note that these aren't q/-q (two quaternions that represent the same rotation); they face completely different directions. I've noticed that with matrices for rotations very close to that one (successive frames in the animation) that the Matrix.Decompose version gives a solution that flips around wildly and occasionally goes into the desired position, while the Quaternion.RotationMatrix version gives solutions that are stable but go in the wrong direction. This is only for the right arm in my animation -- for the left arm, both functions give the correct solution, which is the same quaternion within error tolerances. This makes me think that there's some sort of numeric instability or weird stuff with signs going on. I tried implementing this and then this, but both gave me a completely incorrect solution (even for the matricies where the SlimDX ones were working correctly) -- maybe the rows and columns are flipped?

• Never Bet Against the Impossible

  - by BuckWoody

  My uncle used to say “If a man tells you that his car squirts milk in his eye when you lift the hood, don’t bet against that. You’ll end up with milk in your eye.” My friend Allen White tells me this is taken from a play (and was said about playing cards), but I think the sentiment holds, even in database work. I mentioned the other day that you should allow the other person to talk and actively listen before you propose a solution. Well, I saw a consultant “bet against the impossible”  the other day – and it bit her. She explained to the person telling her the problem that the situation simply couldn’t exist that way, and he proceeded to show her that it did. She got silent, typed a few things, muttered a little, and then said “well, must be something else.” She just couldn’t admit she was wrong. So don’t go there. If someone explains a problem to you with their database, listen with purpose, and then explore the troubleshooting steps you know to find the problem. But keep your absolutes to yourself. In fact, I have a friend that has recently sent me one of those. He connects to a system with SQL Server Management Studio (SSMS) version 2008 (if I recall correctly) and it shows a certain version number of the target system in the connection tab. Then he connects to it using SSMS 2008 R2 and gets a different number. Now, as far as I know, we didn’t change the connection string information, and that’s provided by the target system, so this is impossible. But I won’t tell him that. Not until I look a little more. :) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Facebook Like javascript related to Time Spent Downloading a page Increase in GWT?

  - by donaldthe

  Hi, I installed the Facebook Like button Javascript version on my website on December 15th. Take a look at this report from Google Webmaster Central. Crawl stats Googlebot activity in the last 90 days The crawl stats are from Googlebot which as far as I know doesn't execute Javascript. Could the Facebook Like Javascript code, "The XFBML version" be related to large spike in Time spent downloading a page? (By the way the huge spike in November was caused by a mistake where every image request was getting a 301.) I'm not sure what caused the spike to go down by half somewhere in December. It may have been related to a faulty setting in web.config. I'm at a loss as to what I can do about this or even how to tell if this is my problem or Googlebots crawl problem. Here is the Facebook code I am using to create the like button. It is right after the opening body tag <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({appId: 'xxxxx', status: true, cookie: true, xfbml: true}); }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); ` and this creates the like box: <fb:like show_faces="false"></fb:like> If the Javascript can't be the problem any ideas on where to start looking would be appreciated.

• nVidia 9800 GTX+ X11 fails to initialize. no unity or lightdm

  - by rlemon

  I have just upgraded my work pc to 12.04 (not upgrade, fresh install), installing updates during the install, and after everything has loaded (with no errors) and I restart I get brought to console 1 tty login. Console 7 looks like this: IIRC I did not have to finagle with my drivers on 11.10 to get this card working. If this is in fact a driver bug I will remove this post and submit the bug but i'm not 100% confident that it is. I attempted to run unity --reset and got this: Lastly I tried $ sudo apt-get install nvidia-current which tells me nvidia-current is already the newest version. so I ran $ sudo dpkg-reconfigure nvidia-current which says /usr/sbin/dpkg-reconfigure: nvidia-current is broken or not fully installed. Anything I can try from here would be awesome. Currently the only way to get the system up and running was to shut down, plug one of my monitors into the onboard video, enable the onboard video card from the BIOS, then boot back up (and on my single monitor everything is fine). update So I have been able to boot fresh with the ext card plugged in as long as I don't take the updates with the install. past this if I only install the nvidia drivers (nvidia-current or nvidia-current-updates) from the main server (or canadian) I then get the problems.. My proposal; which I don't know where to look for: Can I try installing the previous version of this driver? In the past, on another machine I had issues with my NIC driver being funky... downgraded to the previous driver and bam everything was merry and well.

  On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

• Best way: restructure an existing Team Foundation Server (TFS) solution

  - by dhh

  In my department we are developing several smaller AddOns for some unified communication server. For versioning and distributed development we use a Team Foundation Server 2012. But: there is only one large TFS solution for all of our applications and libraries: Main Solution Applications App 1 App 2 App 3 Externals Libraries Lib 1 Lib 2 Tools The "Application" path contains all main applications. Those are not depending on each other, but they depend on the Libraries and Externals projects. The "Externals" path contains some external DLLs referenced in our Applications and Libraries. The Libraries path contains commonly used libs (UI templates, Helper classes, etc.). They do not depend on each other and they are referenced in the Libraries and the Tools projects. The Tools path contains some helper programs like setup helpers, update web services, etc. Now, there's some major points why I'd like to change this structure: We can't use server builds. It's uncomfortable to manage TFS scrum management with sprints, impediments, etc. with a solution structure like that. Every developer always has access to all projects in the solution. A complete build lasts too long if one accidentally hits [F6] in Visual Studio... What would you change in this solution? How would you break those projects into smaller Solutions, how should those solutions be structured. My first approach would be, to create one TFS project for each Application, Library and Tool. But how can I ensure that e.g. App 2 always contains the newest version of Lib 1? Do I have to monitor changes on Lib 1 and update App 2 manually as soon as the Lib changes? Or can I somehow force Visual Studio to always use the newest version of an external project somehow?

• StreamInsight V2.0 Released!

  - by Roman Schindlauer

  The StreamInsight Team is proud to announce the release of StreamInsight V2.0! This is the version that ships with SQL 2012, and as such it has been available through Connect to SQL CTP customers already since December. As part of the SQL 2012 launch activities, we are now making V2.0 available to everyone, following our tradition of providing a separate download page. StreamInsight V2.0 includes a number of stability and performance fixes over its predecessor V1.2. Moreover it introduces a dependency on the .NET Framework 4.0, as well as on SQL 2012 license keys. For these reasons, we decided to bump the major version number, even though V2.0 does not add new features or API surface. It can be regarded a stepping stone to the upcoming release 2.1 which will contain significantly new APIs (that will depend on .NET 4.0). Head over here to download StreamInsight V2.0. The updated Books Online can be found here. Update: For instructions on how to make your existing application work against the new bits without recompilation, see here. Regards, The StreamInsight Team

• LDoms with Solaris 11

  - by Orgad Kimchi

  Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page. Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11. The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type. You can migrate guest domain from a system with UltraSPARC  T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system. For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and  Cross CPU Migration refer to the following white paper

• I'm a SubVersion geek, why I should consider or not consider Mercurial or Git or any other DRCS?

  - by Pierre 303

  I tried to understand the benefits of DRCS. I must recognize I still doesn't get it. Here are my current beliefs. I'm ready to destroy them thanks to your expertise. I know I'm probably resisting to change. I just want to evaluate how much that change will cost me. Merging hell can be solved by just applying good practices such as continuous integration. There is no such good practice than having a private branch for a few days when you are in a self managing team with real collaboration. I use branching for that for very rare cases, and I keep a branch for every major version, in which I fix bugs merged from the trunk. I see the value of committing offline then pushing online. But continuous integration can help on this too. I work on very large projects, and I never noticed SubVersion to be slow even when the server is 5000km away on the internet and my small connection (less than 1024D/128U). Harddisk space is cheap, so having a copy of source code locally doesn't look like a problem to me. I already have a full copy of the last version on my disk. I don't understand the distributed thing there (maybe THIS IS the key to my understanding?) I not new in the industry, and judging by my difficulty to understand, I don't think DRCS are easier to understand than SubVersion like. If fact, I don't understand... Doctor, give me your diagnostic.

• Dependency Inversion Principle

  - by Chris Paine

  I have been studying also S.O.L.I.D. and watched this video: https://www.youtube.com/watch?v=huEEkx5P5Hs 01:45:30 into the video he talks about the Dependency Inversion Principle and I am scratching my head??? I had to simplify it(if possible) to get it through this thick scull of mine and here is what I came up with. Code on the marked My_modified_code my version, code marked Original DIP video version. Can I accomplish the same with the latter code? Thanks in advance. Original: namespace simple.main { class main { static void Main() { FirstClass FirstClass = new FirstClass(new OtherClass()); FirstClass.Method(); Console.ReadKey(); //tempClass temp = new OtherClass(); //temp.Method(); } } public class FirstClass { private tempClass _LastClass; public FirstClass(tempClass tempClass)//ctor { _LastClass = tempClass; } public void Method() { _LastClass.Method(); } } public abstract class tempClass{public abstract void Method();} public class LASTCLASS : tempClass { public override void Method() { Console.WriteLine("\nHello World!"); } } public class OtherClass : tempClass { public override void Method() { Console.WriteLine("\nOther World!"); } } } My_modified_code: namespace simple.main { class main { static void Main() { //FirstClass FirstClass = new FirstClass(new OtherClass()); //FirstClass.Method(); //Console.ReadKey(); tempClass temp = new OtherClass(); temp.Method(); } } //public class FirstClass //{ // private tempClass _LastClass; // public FirstClass(tempClass tempClass)//ctor // { // _LastClass = tempClass; // } // public void Method() // { // _LastClass.Method(); // } //} public abstract class tempClass{public abstract void Method();} public class LASTCLASS : tempClass { public override void Method() { Console.WriteLine("\nHello World!"); } } public class OtherClass : tempClass { public override void Method() { Console.WriteLine("\nOther World!"); } }

• Mix10 is in history, Windows Phone 7 is here!

  MIX10was really a fantastic conference for Telerik! We had great talks, many customers stopped by our booth and we've got a lot of great feedback for our Silverlight Controls. Thank you for stopping by and sharing your opinion! So now, that the MIX is over, there is one question left: What Telerik will develop for theWindows Phone 7? We had this question on the booth over and over again and it is no doubt that the WP7 development is a hot topic now. All we can sayat this momentis that Yes, we are looking into this and we actually have some of our controls already partially working with WP7 internally :) You know that the Silverlight version for WP7 is Silverlight 3 and it has some very good additions over it in order to support the phone hardware - like webcam, mic, accelerometer, etc. If you missed the conference and the sessions- here is a list of videos thatwill get you started: Building Windows Phone Applications with Silverlight, Part 1 Mike Harsh Building Windows Phone Applications with Silverlight, Part 2 Peter Torr The good thing isthat our controls will needvery few tweaks in order to be *compiled* against the WP7 Silverlight runtime. But, the more interesting part is actually what are the scenarios that our controls will be used in. How different they will be from the desktop version of the SL? This is where we need your feedback - drop as a line and let us know what are your expectations in this area. Do you need something specific, a feature or a new control that you like to use, or maybe you have a specific scenario that you want to share. Nowthe ball is in your hands - write on the forums, send us a ticket, or just leave your comment on WP7 developmentbelow! 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.
