• Permanently mounting Windows' NTFS partition, fully enabled

  - by Bart van Heukelom

  I'm transforming a Windows 7 PC into a dual boot system with Ubuntu 10.10. Following other questions on this site, I've mounted my Windows drive by adding this to fstab UUID=blabla /windows ntfs users,defaults,umask=000 0 0 It appears to work well, I can read and write, but it appears to be a bit crippled still. When I tried to update an SVN working copy with RabbitVCS, it complained that it couldn't write to a temporary file inside the working copy, even though the permissions are all on 0777 inside /windows (by default, I haven't done that manually). It even corrupted that working copy :( It works when I use the command line SVN client with sudo, but that's hardly user friendly.

• In a browser, is it best to use one huge spritesheet or many (10000) different PNG's?

  - by Nick

  I'm creating a game in jQuery, where I use about 10000 32x32 tiles. Until now, I have been using them all separately (no sprite sheet). An average map uses about 2000 tiles (sometimes re-used PNG's but all separate divs) and the performance ranges from stable (Chrome) to a bit laggy (Firefox). Each of these divs are positioned absolutely using CSS. They do not need to be updated every tick, just when a new map is loaded. Would it be better for performance to use spritesheet methods for the divs using CSS background-positioning, like gameQuery does? Thank you in advance!

• Trouble signing Code of Conduct

  - by Lionthinker

  So I've spent quite some time trying to sign this code of conduct and am on the verge of abandoning it. Got right to the sign the txt file stage https://launchpad.net/codeofconduct/1.1/+sign but now I get an error and am just tired of fighting with Ubuntu. It has to do with the clearsign thing in the terminal. See below $ gpg --clearsign UbuntuCodeofConduct-1.1.txt You need a passphrase to unlock the secret key for user: "Leon Gert Marincowitz (for launchpad) <[email protected]>" 2048-bit RSA key, ID 715FBC94, created 2012-06-16 gpg: can't open `UbuntuCodeofConduct-1.1.txt': No such file or directory gpg: UbuntuCodeofConduct-1.1.txt: clearsign failed: file open error

• Correct order of tasks in each frame for a Physics simulation

  - by Johny

  I'm playing a bit around with 2D physics. I created now some physic blocks which should collide with each other. This works fine "mostly" but sometimes one of the blocks does not react to a collision and i think that's because of my order of tasks done in each frame. At the moment it looks something like this: function GameFrame(){ foreach physicObject do AddVelocityToPosition(); DoCollisionStuff(); // Only for this object not to forget! AddGravitationToVelocity(); end RedrawScene(); } Is this the correct order of tasks in each frame?

• Is the copy/paste approach professionally viable when working with the Google Maps API?

  - by Ian Campbell

  I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

• How to enable TRIM on LVM on Ubuntu 12.10?

  - by Siddarth Kaki

  When I reinstalled Ubuntu 12.10 64-bit on my SSD, I chose the option to use LVM in Ubiquity. I am trying to find out how to enable TRIM for my SSD. I came across this article: http://worldsmostsecret.blogspot.com/2012/04/how-to-activate-trim-on-luks-encrypted.html The article states in addition to adding discard and noatime to /etc/fstab , discard must be added to the drive (sdX_crypt) in /etc/crypttab. My problem is the only listings in my /etc/crypttab are several cryptswap; it does not list any sdX_crypt. I currently have a /dev/sda1 (ext2), which is the boot point, and /dev/mapper/ubuntu-root, which is my ext4 partition. Any ideas as to how to enable TRIM?

• Where did all of the options go? [closed]

  - by Devan

  In the last version of Ubuntu I used (10.04) I had the following options, which I can not find on 11.10: Set amount of time before screen dims Show percent instead of time in battery icon Change/add screensaver Change default applications (especially in the new launcher) Also, is there any way to make it so unity opens to more apps/all instead of the current default? Basically I just need to know if there's any way to customize Ubuntu that little bit more. Any help with any of the options above would be greatly appreciated! Note: I'm a noob and don't know much about command line, so gui apps would be preferred, if possible.

• Unit testing - getting started

  - by higgenkreuz

  I am just getting started with unit testing but I am not sure if I really understand the point of it all. I read tutorials and books on it all, but I just have two quick questions: I thought the purpose of unit testing is to test code we actually wrote. However, to me it seems that in order to just be able to run the test, we have to alter the original code, at which point we are not really testing the code we wrote but rather the code we wrote for testing. Most of our codes rely on external sources. Upon refactoring our code however, even it would break the original code, our tests still would run just fine, since the external sources are just muck-ups inside our test cases. Doesn't it defeat the purpose of unit testing? Sorry if I sound dumb here, but I thought someone could enlighten me a bit. Thanks in advance.

• How to Change the Window Border Size in Windows 8

  - by Chris Hoffman

  The window borders on Windows 8’s desktop are fairly thick by default, but they don’t have to be – you can customize the side of the window borders with an easy-to-use application or a quick registry tweak. You can shrink the window borders and make them fairly thin, just as they were on previous versions of Windows. Or you can increase the window border size and make them extremely thick, if you prefer.. HTG Explains: Does Your Android Phone Need an Antivirus?

• Adding an LOV to a query parameter (executeWithParams)

  - by shay.shmeltzer

  I showed in the past how you can use the executeWithParams operation to build your own query page to filter a view object to show specific rows. I also showed how you can make the parameter fields display as drop down lists of values (selectOneChoice). However this week someone asked me if you can have those parameter fields use the advanced LOV component. Well if you just try and drag the parameter over, you'll see that the LOV option is not there as a drop option. But with a little bit of hacking around you can achieve this. (without actual Java coding). Here is a quick demo:

• My first development job working at a company, what things to look out for?

  - by Kim Jong Woo

  So I've worked on my own all this time, selling software, creating a few web applications on my own. I had an Arts background I was self taught. It was a bit difficult to find a development position after endless trying, I finally landed a LAMP position. What I realized was it was all confidence issue. Before when I didn't know a few things I panicked but after spending such a long time working on my own projects and solving various problems, I felt confident enough that I could fulfill requirements on my own. I hope this helps other people applying for jobs This is the first time I will be developing with other team members in an office, are there anything I should prepare for my first day at work next week? Any tips and pointers while working as a developer at a company? I'm kinda nervous but excited.

• How do I make the jump from developing for Android to Windows Phone 7?

  - by Rob S.

  I'm planning on making the jump over from developing apps for Android to developing apps for Windows Phone 7 as well. For starters, I figured I would port over my simplest app. The code itself isn't much of a problem as the transition from Java to C# isn't that bad. If anything, this transition is actually easier than I expected. What is troublesome is switching SDKs. I've already compiled some basic Windows Phone 7 apps and ran through some tutorials but I'm still feeling a bit lost. For example, I'm not sure what the equivalent of a ScrollView on Android would be on Windows Phone 7. So does anyone have any advice or any resources they can offer me to help me make this transition? Additionally, any comments on the Windows Phone 7 app market (especially in comparison to the Android market) would also be greatly appreciated. Thank you very much in advance for your time.

• How Can Someone With Minimum Programming Experience Publish an App of an Existing Program not found in the Software Centre?

  - by Brenton Horne

  There's a free mathematics software that I would like to see in Ubuntu Software Centre, called, 'Sage.' I have minimal experience in programming, so I'm basically here asking if someone could either tell me how to accomplish this without said instructions being completely over my head or if someone could do it for me. For further information here's the sage homepage: http://sagemath.org/ and the .tar.lzma file for its installation is ~500MB and it takes around 2.2 GB on the HDD when installed, I found at least on 32 bit i386 Ubuntu 12.04 LTS. Any help will be greatly appreciated!

• Defaulting the HLSL Vertex and Pixel Shader Levels to Feature Level 9_1 in VS 2012

  - by Michael B. McLaughlin

  I love Visual Studio 2012. But this is not a post about that. This is a post about tweaking one particular parameter that I’ve found a bit annoying. Disclaimer: You will be modifying important MSBuild files. If you screw up you will break your build tools. And maybe your computer will catch fire. I’m not responsible. No warranties or guaranties of any sort. This info is provided “as is”. By default, if you add a new vertex shader or pixel shader item to a project, it will be set to build with shader profile 4.0_level_9_3. If you need 9_3 functionality, this is all well and good. But (especially for Windows Store apps) you really want to target the lowest shader profile possible so that your game will run on as many computers as possible. So it’s a good idea to default to 9_1. To do this you could add in new HLSL files via “Add->New Item->Visual C++->HLSL->______ Shader File (.hlsl)” and then edit the shader files’ properties to set them manually to use 9_1 via “Properties->HLSL Compiler->General->Shader Model”. This is fine unless you forget to do this once and then submit your game with 9_3 shaders instead of 9_1 shaders to the Windows Store or to some other game store. Then you’d wind up with either rejection or angry “this doesn’t work on my computer! ripoff!” messages. There’s another option though. In “Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\VC\HLSL\1033\VertexShader” (note the path might vary slightly for you if you are using a 32-bit system or have a non-ENU version of Visual Studio 2012) you will find a “VertexShader.vstemplate” file. If you open this file in a text editor (e.g. Notepad++), then inside the CustomParameters tag within the TemplateContent tag you should see a CustomParameter tag for the ShaderType, i.e.: <CustomParameter Name="$ShaderType$" Value="Vertex"/> On a new line, we are going to add another CustomParameter tag to the CustomParameters tag. It will look like this: <CustomParameter Name="$ShaderModel$" Value="4.0_level_9_1"/> such that we now have:     <CustomParameters>       <CustomParameter Name="$ShaderType$" Value="Vertex"/>       <CustomParameter Name="$ShaderModel$" Value="4.0_level_9_1"/>     </CustomParameters> You can then save the file (you will need to be an Administrator or have Administrator access). Back in the 1033 directory (or whatever the number is for your language), go into the “PixelShader” directory. Edit the “PixelShader.vstemplate” file and make the same change (note that this time $ShaderType$ is “Pixel” not “Vertex”; you shouldn’t be changing that line anyway, but if you were to just copy and replace the above four lines then you will wind up creating pixel shaders that the HLSL compiler would try to compile as vertex shaders, with all sort of weird errors as a result). Once you’ve added the $ShaderModel$ line to “PixelShader.vstemplate” and have saved it, everything should be done. Since Feature Level 9_1 and 9_3 don’t support any of the other shader types, those are set to default to their appropriate minimums already (Compute and Geometry are set to “4.0” and Domain and Hull are set to “5.0”, which are their respective minimums (though not all 4.0 cards support Compute shaders; they were an optional feature added with DirectX 10.1 and only became required for DirectX 11 hardware). In case you are wondering where these magic values come from, you can find them all in the “fxc.xml” file in the “\Program Files (x86)\MSBuild\Microsoft.CPP\v4.0\V110\1033” directory (or whatever your language number is; 1033 is ENU and various other product languages have their own respective numbers (see: http://msdn.microsoft.com/en-us/goglobal/bb964664.aspx ) such that Japanese is 1041 (for example), though for all I know MSBuild tasks might be 1033 for everyone). If, like me, you installed VS 2012 to a drive other than the C:\ drive, you will find the vstemplate files in the drive to which you installed VS 2012 (D:\ in my case) but you will find the fxc.xml file on the C:\ drive. You should not edit fxc.xml. You will almost definitely break things by doing that; it’s just something you can look through to see all the other options that the FXC task takes such that you could, if needed, add further CustomParameter tags if you wanted to default to other supported options. I haven’t tried any others though so I don’t have any advice on how to set them.

• A programming language that does not allow IO. Haskell is not a pure language

  - by TheIronKnuckle

  (I asked this on Stack Overflow and it got closed as off-topic, I was a bit confused until I read the FAQ, which discouraged subjective theoratical debate style questions. The FAQ here doesn't seem to have a problem with it and it sounds like this is a more appropriate place to post. If this gets closed again, forgive me, I'm not trying to troll) Are there any 100% pure languages (as I describe in the Stack Overflow post) out there already and if so, could they feasibly be used to actually do stuff? i.e. do they have an implementation? I'm not looking for raw maths on paper/Pure lambda calculus. However Pure lambda calculus with a compiler or a runtime system attached is something I'd be interested in hearing about.

• Worth changing the URL structure to incorporate keywords?

  - by Dejan Pelzel

  I am migrating my blog from PHP to ASP.NET and while recoding the whole website, I figured I might as well improve the URL structure. This is how an url looks like now: example.com/blog/post/755/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana and this is hould it will look after the change (cosplay being the dynamic main keyword of the post): example.com/blog/cosplay/hakurei-reimu-cosplay-from-touhou-by-kishigami-hana-755/ The website is a bit more than a half year old and receives around 650k page views a month, mainly from search traffic. Of course everything would be redirected with 301 redirects. Do you think it is worth changing to a new URL structure, or will it harm the ranking in the long run?

• Is there a way to export all the images of my tweening effect in Flash?

  - by Paul

  i'm using Flash to create the animation of my character in 2D (i'm just beginning). Is it possible to make a tween effect of a character, and then automatically export all the images/frames? So far, it's a bit fastidious : i create my tweening effect, then i put a keyframe for each frame i want to copy and paste, then i select the movieclips and shapes and copy and paste them into another flash document, i position those clips at the exact same location as the previous image, then i erase the previous image and export the image... For 30 frames! Is there any faster way? Thanks

• Run your cpus fast but not hot

  Paul Randall recently blogged about the importance of checking to make sure you are getting every bit of speed you should from your cpus. He recommended that people use CPU-Z , a free tool I recommend and have been using for many years. Power saving features in a cpu are great for laptops. Battery life is greatly extended when a processor isn't running to the max all of the time. But this isn't necessarily a good thing for a server. As Paul and others have pointed out, the processor might not get...(read more)

• What technologies are used for Game development now days?

  - by Monika Michael

  Whenever I ask a question about game development in an online forum I always get suggestions like learning line drawing algorithms, bit level image manipulation and video decompression etc. However looking at games like God of War 3, I find it hard to believe that these games could be developed using such low level techniques. The sheer awesomeness of such games defy any comprehensible(for me) programming methodology. Besides the gaming hardware is really a monster now days. So it stands to reason that the developers would work at a higher level of abstraction. What is the latest development methodology in the gaming industry? How is it that a team of 30-35 developers (of which most is management and marketing fluff) able to make such mind boggling games?

• Great User Group if based near Gloucester + Links from Entity Framework 4.0 session

  I had a really fun evening doing “my final” EF 4.0 session last night (26th May 2010) at GL.NET based out of Gloucester (although secretly I made it into a IronRuby and Windows Azure session). They are a great crowd and Jimmy makes for a fantastic host + it is a very nice venue (Symantec offices in Gloucester, lots of parking, good room etc) + free pizza + free SWAG + trip to pub afterwards (the topics were very varied!). What more could you ask for? The next session is June 16th and will be on multi-tenanted ASP.NET MVC and comes highly recommended.

• Recommended certification to join in a game development internship [on hold]

  - by Conrado Costa

  I'm Brazilian and I'll go to California in July 2014 to study for 1 year and I'm intending to get a winter internship in the game development industry. I'm a programmer since 2008 and I know C#, PHP, Java, Python and a bit of Perl. My question is: do you know any certified required (or helpful) to get a winter job as a game developer? I have no problem to learn new languages, I'm thinking to get a C or C++ certified because I'm not sure about which is the most used language, but before to start a study marathon to take a certification, I have to choose the language and the certification itself. Can you help me, and is that a valid question?
