• How to use short breaks at work effectively for self-development?

  - by Alaudo

  At the moment my daily work as a developer requires me to have short 10-20 min breaks after every 2-3 hours. It would be nice if I could use those effectively to improve my expertise in programming or CS in general. I tried several things: Reading jokes online gets boring very soon. Trying to solve some (even the most simple) tasks from different code contests requires more time, as long as I have some idea of an algorithm the time is over. Reading a randomly picked Wikipedia-article about Computer Science: depending upon the article sometimes it requires more time and is not an easy reading for a break. So, I ended up reading StackOverflow questions and answers with most votes: that is entertaining and educative. Do you have any other suggestions?

• Determining Whether a String Is Contained Within a String Array (Case Insensitive)

  About once every couple of months I need to write a bit of code that does one thing if a particular string is found within an array of strings and something else if it is not ignoring differences in case. For whatever reason, I never seem to remember the code snippet to accomplish this, so after spending 10 minutes of research today I thought I'd write it down here in an effort to help commit it to memory or, at the very least, serve as a quick place to find the answer when the need arises again.So without further adieu, here it is:Visual Basic Version:If stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase) Then ... Else ... End IfC# Version:if (stringArrayName.Contains("valueToLookFor", StringComparer.OrdinalIgnoreCase)) ... else ...Without the StringComparer.OrdinalIgnoreCase the search will be case-sensitive. For more information on comparing strings, see: New Recommendations for Using Strings in Microsoft .NET 2.0.Happy Programming!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.

• Best accounting software for freelance/contractor programmer? [closed]

  - by user1352034

  I know this isn't exactly a programming question but I am hoping to find some programmers who freelance or do contractor work in the US. I have started to work on side jobs and have been billing my clients using Paypal. I then would store those records in a Google excel doc but realize this will get out of hand as time goes on and am looking for a good solution. I am no accountant so I am not sure of everything I would need but I am guessing basic invoicing, expenses, reporting, integration with paypal, etc.. Any contractors or freelancers in here could recommend what they use? I have researched a few but would like to hear what other people are using and how it is working out for them. Thanks for your time!

• Can I get enough experience to get an industry job just by reading books?

  - by MahanGM

  I've been recently working with DirectX and getting familiar with game engines, sub-systems and have done game development for the last 5 years. I have a real question for those whom have worked in larger game making companies before. How is it possible to get to into these big game creators such as Ubisoft, Infinity Ward or EA. I'm not a beginner in my field and I'm going to produce a real nice 2D platform with my team this year, which is the result of 5 years 2D game creation experience. I'm working with prepared engines such as Unity3D or Game Maker software and using .Net with C# to write many tools for our production and proceeding in my way but never had a real engine programming experience 'till now. I'm now reading good books around this topic but I wanted to know: Is it possible to become an employee in big game company by just reading books? I mean beside having an active mind and new ideas and being a solution solver.

• Optimal Database design regarding functionality of letting user share posts by other users

  - by codecool

  I want to implement functionality which let user share posts by other users similar to what Facebook and Google+ share button and twitter retweet. There are 2 choices: 1) I create duplicate copy of the post and have a column which keeps track of the original post id and makes clear this is a shared post. 2) I have a separate table shared post where I save the post id which is a foreign key to post id in post table. Talking in terms of programming basically I keep pointer to the original post in a separate table and when need to get post posted by user and also shared ones I do a left join on post and shared post table Post(post_id(PK), post_content, posted_by) SharedPost(post_id(FK to Post.post_id), sharing_user, sharedfrom(in case someone shares from non owners profile)) I am in favour of second choice but wanted to know the advice of experts out there? One thing more posts on my webapp will be more on the lines of facebook size not tweet size.

• Too much to learn, so little time

  - by Phobia

  Okay, so I'm a java developer (or at least I think I am),and also a student at the same time I want to get a job when I graduate,I'll be graduating in a year or so (hopefully) (Note: my major has nothing to do with programming) Now, I'm between a rock and a hard place I also want to nail the foundations to become a good software developer. I want to be able to write programs that solve problems,not just glue code The software market in my country for java developers is just a few developers working with Java EE (struts,spring,hibernate....etc) I'm currently learning C++ with this book. I've also watched most of the 1st lecture of this course and I understood pretty much everything I watched To sum it up, I have three options Learn Java EE Learn C++ Learn Scheme Which is better for me at this point?

• Trip Report: Scottsdale Arizona Event Conference Planning

  Monday May 10th, 2010 represents my largest and best event to-date, that I have ever hosted. For the last seven years, I’ve grown a technical audience around Microsoft programming / developers in the Phoenix area. Some travel from California, New Mexico, and other parts of Arizona, but for the most part the crowd is local. In years past, this all day event has been as small as 300 folks, and as large as 500, and I’ve tried been to venues around the valley some better than others.

• Render 3d object to 2d surface (embedded system)

  - by Martin Berger

  i am working on an embedded system of a sort, and in some free time i would like to test its drawing capabilities. System in question is ARM Cortex M3 microcontroller attached to EasyMX Stellaris board. And i have a small 320x240 TFT screen :) Now, i have some free time each day and i want to create rotating cube. Micro C PRO for ARM doesnt have 3d drawing capabilities, which means it must be done in software. From the book Introduction to 3D Game Programming with DirectX 10 i know matrix algebra for transformations but that is cool when you have DirectX to set camera right. I gues i could make 2d object to rotate, but how would i go with 3d one? Any ideas and examples are welcome. Although i would prefer advices. I'd like to understand this.

• Shouldn't storage classes be taught early in a C class or book?

  - by Adam Mendoza

  Shouldn't storage classes be taught early in a C class or book? I notice that a lot of books, even some of the better ones, covert it toward and end of the book and some books just add it as an appendix. I would teach it together with variables. This is so foundational and I think unfortunately many do not make it that far in a book. Now that auto has a different meaning (vs being optional) it may confuse people that didn't realize it has always been there. for example: C Programming: A Modern Approach 18.2 Storage Classes 401 Properties of Variables 401 The auto Storage Class 402 The static Storage Class 403 The extern Storage Class 404 The register Storage Class 405 The Storage Class of a Function 406 Summary 407

• problems with studying algorithms

  - by rookie

  hello everyone, I'm currently studying computer science at the Institute, and I have some problems with course which is named Algorithms, I've just begun to study it, but I'm already feeling, that I'm going to fail it, my problem is that while understanding different algorithms on graphs I need to keep in my mind a lot of info, and usually I can't do it, I forget some points of the exercise or can't proceed to final result, I'm very desperate about it cause I like programming very much. Did somebody feel the same while studying in the University? thanks in advance for any help P.S. I began to program only two years ago, may it be the problem?

• How well do free-to-open-source-projects policies work in practice?

  - by Steve314

  In comparison with an open source license and requesting donations, is a free-for-open-source-projects (or free for non-commercial developers) closed source and otherwise commercial project likely to get more license fees? Or just to alienate potential users? Assume the project has value to programmers - I'm looking for generalizations here, though specific examples comparing existing projects will be very interesting. What I have in mind involves code generating programming utilities. And one issue I can think of, either way, is a near total inability to enforce any license restrictions. After all, I can't go around the internet demanding that everyone show me their source code just in case!

• Setting coding priorities

  - by dotnetdev

  Hi, In the dev shops I've worked in, nobody has ever mentioned "coding priorities". I read this in a book or site somewhere, and sets the expectation of what priority should be first in the code. In places where this is not specified, what should the first priority be? It may sound simple to say "do what the business need requires", but that could be at the expense of performance/maintainability. Many people say maintainability first, regardless, some say fulfill the need regardless. I am a young developer, so I am probably missing the point somewhere. Of course, programming is engineering and tough because you can never have the perfect solution. Thanks

• Basics of drawing in 2d with OpenGL 3 shaders

  - by davidism

  I am new to OpenGL 3 and graphics programming, and want to create some basic 2d graphics. I have the following scenario of how I might go about drawing a basic (but general) 2d rectangle. I'm not sure if this is the correct way to think about it, or, if it is, how to implement it. In my head, here's how I imagine doing it: t = make_rectangle(width, height) build general VBO, centered at 0, 0 optionally: t.set_scale(2) optionally: t.set_angle(30) t.draw_at(x, y) calculates some sort of scale/rotate/translate matrix (or matrices), passes the VBO and the matrix to a shader program Something happens to clip the world to the view visible on screen. I'm really unclear on how 4 and 5 will work. The main problem is that all the tutorials I find either: use fixed function pipeline, are for 3d, or are unclear how to do something this "simple". Can someone provide me with either a better way to think of / do this, or some concrete code detailing performing the transformations in a shader and constructing and passing the data required for this shader transformation?

• What's the equivalent name of "procedure" in OOP?

  - by AeroCross

  In several of my programming courses in the University, my teachers always told me the following: A function and a procedure are basically the same thing: the only difference is that a function returns a value, and the procedure doesn't. That means that this: function sum($a, $b) { return $a + $b; } ... is a function, and this: function sum($a, $b) { echo $a + $b; } ... is a procedure. In the same train of thought, I've seen that a method is the equivalent of a function in the OOP world. That means that this: class Example { function sum($a, $b) { return $a + $b; } } Is a method — but how do you call this? class Example { function sum($a, $b) { echo $a + $b; } } What's the equivalent name, or how do you call a method that doesn't returns anything?

• Backtrack My "Education"

  - by perl.j

  About a year or so ago, I decided to start programming. I really, just jumped into a language (Perl) and went from there. What I regret is that I just jumped in: I didn't learn the basics (if you would call them basics). I didn't learn about Computer Science. This issue, I believe, is holding me back. Where should I "restart"? Are there any books, articles, etc. that I should read? Are there any topics an experienced programmer should know? What's your advice? Thanks! Please don't advise me to take a college/high-school class.

• Adding unit tests to a legacy, plain C project

  - by Groo

  The title says it all. My company is reusing a legacy firmware project for a microcontroller device, written completely in plain C. There are parts which are obviously wrong and need changing, and coming from a C#/TDD background I don't like the idea of randomly refactoring stuff with no tests to assure us that functionality remains unchanged. Also, I've seen that hard to find bugs were introduced in many occasions through slightest changes (which is something which I believe would be fixed if regression testing was used). A lot of care needs to be taken to avoid these mistakes: it's hard to track a bunch of globals around the code. To summarize: How do you add unit tests to existing tightly coupled code before refactoring? What tools do you recommend? (less important, but still nice to know) I am not directly involved in writing this code (my responsibility is an app which will interact with the device in various ways), but it would be bad if good programming principles were left behind if there was a chance they could be used.

• UDK/ UnrealScript class interaction? HUD advice?

  - by Holly

  Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

• What does the English word "for" exactly mean in "for" loops?

  - by kol

  English is not my first language, but since the keywords in programming languages are English words, I usually find it easy to read source code as English sentences: if (x > 10) f(); = "If variable x is greater than 10, then call function f." while (i < 10) ++i; = "While variable i is less than 10, increase i by 1." But how a for loop is supposed to be read? for (i = 0; i < 10; ++i) f(i); = ??? I mean, I know what a for loop is and how it works. My problem is only that I don't know what the English word "for" exactly means in for loops.

• advice for a new software engineer/developer right out of college

  - by ranzy

  I just graduated recently from a 4-year university with a degree in Computer Science and thankfully got a job in Software Engineering. I'm working with C++ with a .NET framework if that's correct to say because that also confuses me. What I'm asking for is what tutorials/books are out there to learn C++ for Windows Programming I guess? I know how to program somewhat and I understand the concepts but when I look at the code it doesn't make sense to me. I know I just started so it's kind of expected but it's certainly quite different from college. Thanks!

• What's the best way to get up to speed with Java?

  - by Kosta

  I'm a software developer that just switched teams so I shall write code in Java now. Last time I wrote something in the language was in programming 101 at uni (I was already an amateur coder back then). So what is the best book/tutorial to get up to speed with Java? Where's the Java - the good parts? Learn you some Java for great good? Learn Java the hard way? Or is it too enterprisey for that kind of passion...?

• How does the "Fourth Dimension" work with arrays?

  - by Questionmark

  Abstract: So, as I understand it (although I have a very limited understanding), there are three dimensions that we (usually) work with physically: The 1st would be represented by a line. The 2nd would be represented by a square. The 3rd would be represented by a cube. Simple enough until we get to the 4th -- It is kinda hard to draw in a 3D space, if you know what I mean... Some people say that it has something to do with time. The Question: Now, that is all great with me. My question isn't about this, or I'd be asking it on MathSO or PhysicsSO. My question is: How does the computer handle this with arrays? I know that you can create 4D, 5D, 6D, etc... arrays in many different programming languages, but I want to know how that works.

• Comparing the Performance of Visual Studio&apos;s Web Reference to a Custom Class

  As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using <a href="http://www.4guysfromrolla.com/articles/120705-1.aspx">ASP.NET's Membership system</a> is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a <a href="http://www.4guysfromrolla.com/articles/100803-1.aspx">web service</a> generates markup that auto-creates a <i>proxy class</i>, which handles the low-level details of invoking the web service, serializing parameters,

• Online iPad 1&2 emulators give different results compared to the real thing

  - by Systembolaget

  I'm designing a centered website (jQuery Isotope). Thre sandbox is here. I have used some online iPad 1&2 emulators to test how the site is viewed on these devices. Then, I managed to get hold of the real thing. Result: on real iPads, the site is centered and the layout adjusts automatically as expected. In online iPad emulators, the site is not quite centered and additional Isotope elements are squeezed in. Of course, I trust the real thing more than online emulators, but why is this happening? To me, it feels like website testing with online emulators is not so reliable after all? If this question is wrong here, please move it or tell me where it should go. SO is about programming, this question isn't. Thanks!
