• How do I apply a computer science degree to web development?

  - by T. Webster

  I'm a web programmer, but I haven't found many opportunities to take advantage of a formal education in computer science. Maybe I'm not looking in the right places, but it seems to me like most of the web jobs I come across are CRUD, web forms, and data grids. For these jobs a formal CS background doesn't seem necessary, and you could do fine with O'Reilly cookbooks in jQuery, CSS 3, PHP, SQL, or ASP.NET MVC. What kinds of web developer jobs exist that really let you apply your computer science background? Do I need to branch out into other areas of programming to take full advantage of my degree?

• Drawing different per-pixel data on the screen

  - by Amir Eldor

  I want to draw different per-pixel data on the screen, where each pixel has a specific value according to my needs. An example may be a random noise pattern where each pixel is randomly generated. I'm not sure what is the correct and fastest way to do this. Locking a texture/surface and manipulating the raw pixel data? How is this done in modern graphics programming? I'm currently trying to do this in Pygame but realized I will face the same problem if I go for C/SDL or OpenGL/DirectX.

• Are developers expected to have skills of business analysts?

  - by T. Webster

  Our business analyst has left the team. We are now expected to do the work which was previously done by the business analyst, and the management thinks that a task which is done in three months by a business analyst can be done in one month by a developer. My experience is in programming only, and I'm not familiar to the business intelligence tools. To me this seems like maybe an unfair comparison or expectation, and might even trivialize the role of a business analyst. Has anyone else encountered this situation? How to deal with it?

• How do I pass tests with higher scores? [closed]

  - by user1867842

  How do I pass a test of programming knowledge for a higher score on oDesk.com? I have passed php and javascript tests but I have passed them with low scores and barley passing. This doesn't look too appealing for clients and I'm afraid that is the reason I am not being hired for a job. I know I am capable of doing web work and such. But I haven't been accepted for an interview or anything. Any idea how to study for something like this ?

• What are best practices for testing programs with stochastic behavior?

  - by John Doucette

  Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!

• How to program something with the expectation that it will work the first time?

  - by Peter Turner

  I had a friend in college who programmed something that worked the first time, that was pretty amazing. But as for me, I just fire up the debugger as soon as I finally get whatever I'm working on to compile - saves me time (kidding of course, I sometimes hold out a little bit of hope or use a lot of premeditated debug strings). What's the best way to approach the Dijkstrain ideal for our programs? -or- Is this just some sort of pie-in-the-sky old fools quest for greatness applicable only to finite tasks that no one should hope for in our professional lives because programming is just too complex?

• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• Plan variable and call dependencies

  - by Gerenuk

  I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

• Free LINQPad is a great way to learn LINQ!

  - by CatherineRussell

  LINQPad is a great way to learn LINQ: it comes loaded with 500 examples from the book, C# 4.0 in a Nutshell.  There's no better way to experience the coolness of LINQ and functional programming. LINQPad is more than just a LINQ tool: it's an ergonomic C#/VB scratchpad that instantly executes any C#/VB expression, statement block or program with rich output formatting – the ultimate in dynamic development. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder! Best of all, LINQPad standard edition is free and can run without installation (or with a low-impact setup). The executable is 3MB and is self-updating. To get it, go to: http://www.linqpad.net/

• Shouldn't we count characters of code and comments instead of lines of code and comments? [closed]

  - by Gabriel

  Counting lines of code and comments is sometimes bogus, since most of what we write may be written in one or more lines, depending column count limitations, screen size, style and so forth. Since the commonly used languages (say C, C++, C# and Java) are free-form, wouldn't it be more clever to count characters instead? Edit: I'm not considering LOC-oriented programming where coders try to artificially match requirements by adding irrelevant comments or using multiple lines where less would be enough (or the opposite). I'm interested in better metrics that would be independent of coding style, to be used by honest programmers.

• Alternative to Google Adsense which has good international coverage

  - by Yoga

  I have a technical blog (programming related) which has around 500 visit per days, 70% are international visitors and 30% are from US/CA. Google Adsense disabled my account due to invalid clicks so I can't use them (no need to explain here, they suck hard and never respect and listen to the publishers' appeal) I have tried adbrite and recently using chitika but they almost give me nothing, e.g. chitika 13,865 Page Views 4 clicks $0.01 The performance is so poor even I don't want to mention about it. I am already putting a full top banner and a 350x200 box in article body. I am researching if any alternative would provide more revenue for my internation visitors or technical visitors. Thanks.

• What is the worst software bug in history? [closed]

  - by Amir Rezaei

  By having for example money and human suffering as the metric. What is the worst software bug in history? Note this is a specific question. Last month automaker Toyota announced a recall of 160,000 of its Prius hybrid vehicles following reports of vehicle warning lights illuminating for no reason, and cars' gasoline engines stalling unexpectedly. But unlike the large-scale auto recalls of years past, the root of the Prius issue wasn't a hardware problem -- it was a programming error in the smart car's embedded code. The Prius had a software bug.

• What is the difference between Constant Vertex Attributes and Uniforms?

  - by Samaursa

  According to the OpenGL ES 2.0 Programming Guide: A constant vertex attribute is the same for all vertices of a primitive, and therefore only one value needs to be specified for all the vertices of a primitive. For uniforms the book states: ...any parameter to a shader that is constant across either all vertices or fragments (but that is not known at compile time) should be passed in as a uniform. I've always used uniforms for data that is constant for a primitive but now it appears that attributes can also be used in the same way. Is there more to constant vertex attribute than simply 'they are the same as uniforms'?

• Best keyboard to use with RollerMouse

  - by jrdioko

  I recently purchased a RollerMouse, which seems like an excellent way to eliminate pain caused by mousing. My question is: what good keyboard can other programmers recommend that would work well with it. I currently have a Microsoft ergonomic keyboard, but the curve and large wrist rest make it hard to use with the RollerMouse. By "good", I mean: Works with the RollerMouse (no wrist rest) Ergonomic (a slight curve or other features designed to be easy on your wrists/arms) Good for programming (that would be its primary use, no need for fancy media buttons or anything like that) Suggestions?

• Techniques for Working Without a Debugger [closed]

  - by ashes999

  Possible Duplicate: How to effectively do manual debugging? Programming in a debugger is ideal. When I say a debugger, I mean something that will allow you to: Pause execution in the middle of some code (like a VM) Inspect variable values Optionally set variable values and call methods Unfortunately, we're not always blessed to work in environments that have debuggers. This can be for reasons such as: Debugger is too too too slow (Flash circa Flash 8) Interpreted language (Ruby, PHP) Scripting language (eg. inside RPG Maker XP) My question is, what is an effective way to debug without a debugger? The old method of "interleave code with print statements" is time-consuming and not sufficient.

• "A good programmer can be as 10+ times more productive as a mediocre one"

  - by m3th0dman

  I had read an interview with a great programmer (it is not in English) and in it he said that "a great programmer can be as 100 times as good as a mediocre one" giving reason for why good programmers are very well paid and why programming companies give many facilities for their employees. The idea was that there is a very large demand for good programmers, because of the above reason and that's why companies pay very much to bring them. Do you agree with this statement? Do you know any objective facts that could support it? Edit: The question has nothing to do with experience; if you talk about one great programmer with 1 year experience then s/he should be 10 times more productive than a mediocre programmer with 1 year experience. I agree that from certain experience years onwards, things start to dissipate but that's not the purpose of the question.

• Passive Income for a programmer : Teaching

  - by Victor

  While looking into passive income streams for someone with a Science/math/Engineering/Programming background, I ran into various ideas. I was looking to generate a passive income that would not take too much of an initiall learning curve. And it occurs to me that teaching/writing books/ on High School math/Physics/English is something I can do without a lot of prepwork. I am in Toronto . what are the average income opportunities for something like this? Where should I start looking?

• Version 5.1.3 of ReSharper released

  - by TATWORTH

  Version 5.1.3 of Resharper has been released by Jetbrains. Download is at http://www.jetbrains.com/resharper/whatsnew/index.html The release notes are at http://blogs.jetbrains.com/dotnet/2011/02/resharper-513-is-released/ Whilst 5.1.3 addresses just a specific issue, if you are programming in C# or VB.NET and if you have never tried Resharper before, you should try it. When I first saw ReSharper in use, within a few minutes I knew that it was worthwhile buying my own copy. Since then I have used it at client site after client site and found it to be a very useful tool.

• Application won't run when installed in "/opt"

  - by Sam Hewitt

  I've developed a program for the App Developer Showdown, with quickly, in python, and it works as expected when I package and install it normally -in /usr. However when packaged for installation in /opt it doesn't run -and I'm not getting (or can't find) an error message of any sort, as to what the problem might be. I was wondering if someone here has the answer. The app does require root access -using gksudo- to function. I'm fairly new to programming, but not to Linux. Thanks, Sam Launchpad: https://launchpad.net/aplomb

• How to identify potential for becoming a programmer

  - by Jacob Spire

  There's heaps of information out there on hiring someone who's already a programmer. (Or claims to be one.) But what about identifying someone who has the potential to become a programmer, with little or no knowledge? Aside from the obvious things to look for (smart, gets things done), are there any interview questions and/or tests to determine whether one has the potential to become a programmer? Note: I'm not asking how to tell whether I can learn programming, but how to tell someone else is right for it.

• How do I install the driver for my Linksys AE1200 Wireless-N USB Adapter?

  - by Lewis Graham

  I recently downloaded Ubuntu from the main website with the hopes of dual booting it with Windows. While the operating system works, it says that I need to install a driver for my graphics card. When I type in my password the installation fails. I figure it is because I need Internet access. I tried to install my WiFi USB adapter with the installation disc but Ubuntu doesn't seem to run the setup when I click the exe. What are my available solutions as I would really like to use Ubuntu from my programming and Windows for my gaming needs? The name as read on the box is: Linksys AE1200 Wireless- N USB Adapter The description reads as such: ID 13b1:0039 Linksys (a comma messed up format) ID 046d:0a0b Logitech, Inc.

• converting 2d grid of squares to polygon nav mesh

  - by Roflha

  I haven't actually started programming for this one yet, but I wanted to see how I would go about doing this anyway. Say I have a 2D matrix of squares, all of the same size, some traversable and some not. How would I go about creating a navigation mesh of polygons from this grid. Is there any reading I can look at until I get a chance to get to my computer or should I just give it a go. My idea was to take the non-traversable squares out and extend lines from there edges to make polygons.. that's all I have got so far. Any advice?

• what knowledge would I need to make a good simulation games

  - by Skeith

  I have an idea for a game like theme park but don't know how simulation games are made. I am not some noob on his first game so I appreciated constructive answers instead of "its hard, don't do it". What I want is to know how simulation game mechanics are put together. I figure it would be heaver on the AI than normal games and not knowing much about AI would like to know some programming techniques I should look into for this style game. specific techniques please not just a book on ai. what sort of architecture would be used? I guess it would have some sort of probability engine with pre designed events that are triggered based on the AI state. Would it use a FSM or be purely event driven ? Any information on how a sims game functions would be cool.
