• Disable incognito in chrome or chromium

  - by TheIronKnuckle

  I'm addicted to certain websites to the point where it's interfering with my life regularly and sick of it. I want to install website blockers that aren't easy to circumvent. In Chrome, incognito mode is easily accessible with a ctrl-shift-n. That is ridiculous. Whenever I feel an urge to go on an addictive website, it doesn't matter what blockers and regulators I've got installed; three keys can get round them in a second. Simply uninstalling chrome isn't an option either, as it's way too easy to sudo apt-get install it right back. So yes, I want to disable incognito mode completely (and if possible making it totally impossible to get it back). I note that some guy has figured out how to do it on windows with a registry entry: http://wmwood.net/software/incognito-gone-get-rid-of-private-browsing/ If it can be done on windows it can be done on ubuntu!

• What do you look for in a scripting language?

  - by Jon Purdy

  I'm writing a little embedded language for another project. While game development was not its original intent, it's starting to look like a good fit, and I figure I'll develop it in that vein at some point. Without revealing any details (to avoid bias), I'm curious to know: What features do you love in a scripting language for game development? If you've used Lua, Python, or another embedded language such as Tcl or Guile as your primary scripting language in a game project, what aspects did you find the most useful? Language features (lambdas, classes, parallelism) Implementation features (performance optimisations, JIT, hardware acceleration) Integration features (C, C++, or .NET bindings) Or something entirely different?

• What should I worry about when changing OpenGL origin to upper left of screen?

  - by derivative

  For self education, I'm writing a 2D platformer engine in C++ using SDL / OpenGL. I initially began with pure SDL using the tutorials on sdltutorials.com and lazyfoo.net, but I'm now rendering in an OpenGL context (specifically immediate mode but I'm learning about VAOs/VBOs) and using SDL for interface, audio, etc. SDL uses a coordinate system with the origin in the upper left of the screen and the positive y-axis pointing down. It's easy to set up my orthographic projection in OpenGL to mirror this. I know that texture coordinates are a right-hand system with values from 0 to 1 -- flipping the texture vertically before rendering (well, flip the file before loading) yields textures that render correctly... which is fine if I'm drawing the entire texture, but ultimately I'll be using tilesets and can imagine problems. What should I be concerned about in terms of rendering when I do this? If anybody has any advice or they've done this themselves and can point out future pitfalls, that would be great, but really any thoughts would be appreciated.

• Aliasing resellers domain to primary domain

  - by Ashkan Mobayen Khiabani

  I have designed a website that accepts re-sellers and actually the concept of this website is having local re-sellers for each province (or should we say branches). I have designed this website in a way that anybody who has a domain, can point to our website (a record or cname). well most of the website content are the same, the only difference is that re-sellers website doesn't have some items on the main menu and may have some small descriptions of their own branch in some pages. I read that Google may ban websites with duplicate content (or which are significantly similar). I want to know will this be a problem for me? If yes, what else can I do? we have had considered asking our reseller to use iframe that loads our website but wanted that each reseller can have its own SEO and try harder but what I read about this duplicate thing worries me.

• 302 Redirect causes garbage at end of Wordpress link in Facebook

  - by Joao

  When I try to link my Wordpress blog to Facebook, the url doesn't resolve properly. There's garbage appended at the end and Facebook is not able to retrieve information from the site. Happens in every page, post or main entry. Here's what happens: http://clarissarezende.com.br/ shows up in Facebook as http://clarissarezende.com.br/UPLcS/ (when copy/paste the link) and no information about the site shows up in FB. I'm using Wordpress 3.3.1 with ProPhoto 4. Recently I moved the DNS entry on my ISP. The blog is hosted at clarissarezende.com.br/public_html/blog2 and before the DNS would point to public_html and then I changed it to public_html/blog2. Note that I did not move any Wordpress files. Made the (I think) necessary changes all over Facebook, but still no dice... Any ideas on what can be happening?

• Am I getting Scheme wrong?

  - by nischayn22

  Inspired by the numerous posts about the importance of learning Lisp/Scheme I started to learn Scheme two days back, I am using the book "The little Schemer" and have completed half of it. But I still haven't learned anything new, the book teaches about recursion which I already understand and uses lambda (which I can think of a way to define a function in C). I still haven't got the concept of functional programming (please point to some example of functional compared to normal programming methods in C/C++ so I can get it). Am I learning in the wrong way? or is "The little Schemer" for a newbie in programming and I should look for some other books?

• Mount to /dev/sdb1 without password

  - by Jarmo

  I am unable to mount a USB drive (or SD card) to my system without root access. When I plug in a USB drive, it is visible in the left column of Nautilus, but when I click on it to open it, I receive the error message Unable to mount 2.1 GB Filesystem Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sdb1 on /media/sdb1 I am able to mount the drive using sudo mount -w /dev/sdb1, but this causes problems for operations such as creating startup discs, which requires unmounting and remounting the drive. I suspect this problem may be caused by the fact that when I upgraded from 11.10 to 12.04, I had an SD card plugged in. This caused the system to stall during later startups, as it could not find this drive. I remedied this by editing a line of /etc/fstab to read /dev/sdb1 /media/sdb1 vfat noauto 0 0 However, I am dual booting Ubuntu with Windows XP, and I have no problem mounting the C: drive of the Windows system without root access, so I feel that this is a problem related to the mount point rather than mounting in general.

• Why are so many questions closed? [closed]

  - by Kim Jong Woo

  Why is there so many questions on this stackexchange site closed? I mean far more than usual. Even very high quality discussions are closed. Doesn't this high number of closed questions with high number of views and good quality of content seem like that the current policy that governs the criteria for appropriate question might be going against nature? I mean it feels as if lot of questions or discussions are everything surrounding programmer, programming, and need not be objective or seeking definitive answer. It appears lot of questions are of inquisitive nature seeking insight into other programmers and finding common subjects of interest. Is it possible for mods to relax a bit? I mean lot of great questions with [closed] tag everywhere doesn't do justice. This question in itself is a perfect example of what I am talking about and it will be closed. But I think my point is clear.

• How to market yourself as a software developer?

  - by karlphillip

  I have noticed that this is a frequent issue among younglings from technical areas such as ours. In the beginning of our careers we simply don't know how to sell ourselves to our employers, and random guy #57 (who is a programmer, but not as good as you - technically) ends up getting a raise/promotion just because he knows how to communicate and market himself better than you. Many have probably seen this happen in the past, and most certainly many more will in the future. What kind of skill/ability (either technical, or of other nature) do you think is relevant to point out when doing a job interview or asking for a raise, besides listing all the programming languages and libraries you know?

• 3D Modeling Software for Programmer [closed]

  - by Pathachiever11

  I've recently learned how to make games for Unity3d, and now I want to start making games! I can't wait to start! However, before I can make 3D games, I need to learn 3D modeling for character design, level design, and some animation. What is the easiest 3D modeling software, compatible with Unity3d? I do not want to spend too much time learning the software. From what I've heard, Blender is a bit complicated to use. Maya and 3dsMax seem very powerful. Could someone point me in the right direction? I don't want to spend a lot of time learning. I know its not that easy, but you guys have experience, you guys probably know out of all which one is easier and powerful. Could you recommend a software? Many Thanks!

• Mobile Web or Objective-C?

  Cameron Moll is worried about a future in which we’ll all write Objective-C for the iPhone OS instead of writing web standards for the mobile web.At one point in time, J2ME (now Java ME) and WAP were the starting points for a discussion on mobile strategy and the web. Then, for a brief period of time, you talked about HTML/CSS. Now, for a growing majority of mobile strategies that don’t require a global presence on widely varying devices, the discussion begins with iPhone.Emphasis mine. Strategy...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.

• SQLIO Writes

  - by Grant Fritchey

  SQLIO is a fantastic utility for testing the abilities of the disks in your system. It has a very unfortunate name though, since it's not really a SQL Server testing utility at all. It really is a disk utility. They ought to call it DiskIO because they'd get more people using I think. Anyway, branding is not the point of this blog post. Writes are the point of this blog post. SQLIO works by slamming your disk. It performs as mean reads as it can or it performs as many writes as it can depending on how you've configured your tests. There are much smarter people than me who will get into all the various types of tests you should run. I'd suggest reading a bit of what Jonathan Kehayias (blog|twitter) has to say or wade into Denny Cherry's (blog|twitter) work. They're going to do a better job than I can describing all the benefits and mechanisms around using this excellent piece of software. My concerns are very focused. I needed to set up a series of tests to see how well our product SQL Storage Compress worked. I wanted to know the effects it would have on a system, the disk for sure, but also memory and CPU. How to stress the system? SQLIO of course. But when I set it up and ran it, following the documentation that comes with it, I was seeing better than 99% compression on the files. Don't get me wrong. Our product is magnificent, wonderful, all things great and beautiful, gets you coffee in the morning and is made mostly from bacon. But 99% compression. No, it's not that good. So what's up? Well, it's the configuration. The default mechanism is to load up a file, something large that will overwhelm your disk cache. You're instructed to load the file with a character 0x0. I never got a computer science degree. I went to film school. Because of this, I didn't memorize ASCII tables so when I saw this, I thought it was zero's or something. Nope. It's NULL. That's right, you're making a very large file, but you're filling it with NULL values. That's actually ok when all you're testing is the disk sub-system. But, when you want to test a compression and decompression, that can be an issue. I got around this fairly quickly. Instead of generating a file filled with NULL values, I just copied a database file for my tests. And to test it with SQL Storage Compress, I used a database file that had already been run through compression (about 40% compression on that file if you're interested). Now the reads were taken care of. I am seeing very realistic performance from decompressing the information for reads through SQLIO. But what about writes? Well, the issue is, what does SQLIO write? I don't have access to the code. But I do have access to the results. I did two different tests, just to be sure of what I was seeing. First test, use the .DAT file as described in the documentation. I opened the .DAT file after I was done with SQLIO, using WordPad. Guess what? It's a giant file full of air. SQLIO writes NULL values. What does that do to compression? I did the test again on a copy of an uncompressed database file. Then I ran the original and the SQLIO modified copy through ZIP to see what happened. I got better than 99% compression out of the SQLIO modified file (original file of 624,896kb went to 275,871kb compressed, after SQLIO it went to 608kb compressed). So, what does SQLIO write? It writes air. If you're trying to test it with compression or maybe some other type of file storage mechanism like dedupe, you need to know this because your tests really won't be valid. Should I find some other mechanism for testing? Yeah, if all I'm interested in is establishing performance to my own satisfaction, yes. But, I want to be able to compare my results with other people's results and we all need to be using the same tool in order for that to happen. SQLIO is the common mechanism that most people I know use to establish disk performance behavior. It'd be better if we could get SQLIO to do writes in some other fashion. Oh, and before I go, I get to brag a bit. Measuring IOPS, SQL Storage Compress outperforms my disk alone by about 30%.

• Is there a cross-platform special directory I can use for game save files?

  - by Suds

  I'm developing with LWJGL and Java on a Windows 7 laptop. I've successfully set up saving to the %appdata%\gamename\saves\ or long form c:\users\user\appdata\roaming\gamename\saves\ folder by using File dir = new File(System.getenv("APPDATA") + "\\gamename\\saves\\");. I have hobbyist level experience with Linux, and zero experience with OSX. My game will be fully cross platform. Is System.getenv("APPDATA"); cross platform? If so, where does it point to on Linux or OSX? Is there a best practices alternative that I should use?

• Webhosting with custom database choice [closed]

  Possible Duplicate: How to find web hosting that meets my requirements? I am trying to find somewhere to host a website which uses OrientDB as its database. My budget doesn't stretch to a dedicated server where I can configure everything as I need it. Rather, I am hoping to find somewhere, ideally UK based, that will allow me to install/install for me OrientDB on their server, that is of the normal shared server variety. Is anybody able to point me in a good direction for this please (whilst UK is preferable it is not essential)?

• Tools to manage sql 2008 database mirroring?

  - by lemkepf

  We are going to be moving about 20 databases that live on a single instance of sql 2000 to a sql 2008 r2 environment with database mirroring. What I'm looking for is a tool or scripts that will help me manage the conversion and management of those 20db's onto this new mirrored environment easily. There are many steps in setting each DB up and I want to automate as much as possible. Edit: Here are the steps I've been doing manually: Create the same username/passwords from the old sql 2000 server onto new sql 2008 server. Then sync those users/passwords onto the other sql 2008 server with the same SSID's so when we do the db backup and restore they match up. Take a backup of each sql 2000 db's. Copy them to server A. Restore the backup to server A. Backup from server a, copy to server b, restore there. Run the mirror "configure security" wizard. Start mirroring. I've love to be able to script this out or have a tool that does it for me. Thanks! Paul

• Design a Distributed System

  - by Bonton255

  I am preparing for an interview on Distributed Systems. I have gone through a lot of text and understand the basics of the area. However, I need some examples of discussions on designing a distributed system given a scenario. For example, if I were to design a distributed system to calculate if a number N is primary or not, what will the be design of the system, what will be the impact of network latency, CPU performance, node failure, addition of nodes, time synchronization etc. If you guys could present your in-depth thoughts on this example, or point me to some similar discussion, that would be really helpful.

• Switching songs - MediaPlayer lags the game

  - by Fibericon

  When the player encounters a boss in the game I'm working on, I want to have the music change. It seems simple enough with the MediaPlayer class to fade out the current song, switch to another, and then fade the new song in. However, at the point where the second song starts, the game freezes for a split second. The songs in question aren't particularly large either - the first song is 1.7mb and the second song is 3.1mb, both mp3 format. This is the code I'm using to do it: protected void switchSong(GameTime gameTime) { if (!bossSongPlaying) { MediaPlayer.Volume -= ((float)gameTime.ElapsedGameTime.TotalSeconds/10); if (MediaPlayer.Volume < 0.05f) { MediaPlayer.Play(bossSong); MediaPlayer.Volume = 1.0f; bossSongPlaying = true; } } } What can I do to eliminate that momentary hang?

• "A", "an", and "the" in method and function names: What's your take?

  - by Mike Spross

  I'm sure many of us have seen method names like this at one point or another: UploadTheFileToTheServerPlease CreateATemporaryFile WriteTheRecordToTheDatabase ResetTheSystemClock That is, method names that are also grammatically-correct English sentences, and include extra words purely to make them read like prose. Personally, I'm not a huge fan of such "literal" method names, and prefer to be succint, while still being as clear as possible. To me, words like "a", "an", and "the" just look plain awkward in method names, and it makes method names needlessly long without really adding anything useful. I would prefer the following method names for the previous examples: UploadFileToServer CreateTemporaryFile WriteOutRecord ResetSystemClock In my experience, this is far more common than the other approach of writing out the lengthier names, but I have seen both styles and was curious to see what other people's thoughts were on these two approaches. So, are you in the "method names that read like prose" camp or the "method names that say what I mean but read out loud like a bad foreign-language-to-English translation" camp?

• How to calculate vertext normals for a mesh in Java in OpenGL ES application?

  - by alan mc

  Can some one point me to Java code ( in Java not C or C++) that calculates all the normals for all the vertices of a mesh for OpenGL ES application. I need this for lighting. Lets say I have a cube with following vertices and indices: float vertices[] = { -width, -height, -depth, // 0 width, -height, -depth, // 1 width, height, -depth, // 2 -width, height, -depth, // 3 -width, -height, depth, // 4 width, -height, depth, // 5 width, height, depth, // 6 -width, height, depth // 7 }; short indices[] = { 0, 2, 1, 0, 3, 2, 1,2,6, 6,5,1, 4,5,6, 6,7,4, 2,3,6, 6,3,7, 0,7,3, 0,4,7, 0,1,5, 0,5,4 }; In above specific example how many normals we need ?

• Creating a SOLID Visual Studio Solution

  The SOLID acronym describes five object-oriented design principles that, when followed, produce code that is cleaner and more maintainable. The last principle, the Dependency Inversion Principle, suggests that details depend upon abstractions. Unfortunately, typical project relationships in .NET applications can make this principle difficult to follow. In this article, I'll describe how one can structure a set of projects in a Visual Studio solution such that DIP can be followed, allowing for the creation of a SOLID solution. You can download the sample solution and use it as a starting point for your new solutions if you like.

• This not having job, is driving me nuts!

  - by Ratman21

  I had two jobs lined up (temporary but, hey they pay), one of which was in IT. A very low paying IT job for only 30 hours a week and only 3 weeks. At a large high tech company and a government (a not in my field job) temporary, paying a bit more, for little longer and for up to 40 hours a week. I was going to happily work my little self raged for the next 3 weeks. Guess what, the IT job fell thru and I now feel so let down. This I felt was my chance to get back in to IT, even if it was only for few weeks and maybe get note-us as hard working IT guy. I still have the other job but, let me add that there is no chance that it will turn in to something longer (I have been told that point blank). As I said this is nuts.
