• Is software innovation still primarily North American and European? Why, and for how much longer?

  - by limist

  Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

• Is Java free/open source or it isn't?

  - by user1598390

  On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

• How should I do 3D games through Java on a mac?

  - by Steven Rogers

  I have been self-teaching myself Java on the mac mostly because the language is cross-platform. Recently, I have been only able to develop 2D games using the Graphics2D class. Now, I want to learn how to make 3D games in Java. I used to model and animate stuff in 3D, so my knowledge of 3-Dimensional stuff is okay. I have spent the last 3 hours using google to look up ways of making 3D games in java. Apparently the best one to use is OpenGL, so i looked up a tutorial on it and i cannot find a tutorial that shows how to (if there is a way) install JOGL on the Mac platform. Should i continue to use Java? How can i make 3D games using Java? What is the best way to make 3D games on a mac?

• Editable block: CMS or PHP script?

  - by Jane

  I'm designing a Website for a restaurant. The site will be fairly static except for a 'specials' block which the client will need to update on a daily basis. I'm more of a designer/front-end developer so I was wondering if I was better off trying to make a block editable in PHP (a language I hardly ever deal with) or just create the website in a user-friendly CMS such as Wordpress (which I have some experience with) or Expression Engine (which I have no experience with but I'm told is a favorite in the design community)... certainly not Drupal, because even though I have theming experience with it, I think it would be a little overkill for just one editable block in a five-page site. I'm leaning towards an easy to use CMS because I'm really just not comfortable writing my own PHP especially since I guess a PHP solution would also require an authentication solution so only the client could get in to edit their info. Any insight would be appreciated!

• What tools should I consider if my aim is to make a game available to as many platforms as possible?

  - by Kenji Kina

  We're planning on developing a 2D, grid-based puzzle game, and although it's still very early in the planning stages, we'd like to make our decisions well from the beginning. Our strategy will be to make the game available to as many platforms as possible, for example PCs (Windows, Mac and/or Linux), mobile phones (iPhone and/or Android based phones), game consoles (XBLA and/or PSN) PC will have an emphasis, but I believe that's the most flexible platform so that shouldn't be a problem. So, what programming language, game engine, frameworks and all around tools would be best suited for our goal? P.S.: I'm betting a set of tools won't cover ALL of them, and that there will still be some kind of "translating" effort for some platforms, but we'd like to know what the most far reaching are.

• Copying logins to another server

  - by DavidWimbush

  I'm busy setting up a new server to replace our main live server and part of that is to get the logins copied over. The database users will come over when I restore the databases but I wanted to get the logins they relate to, with the same SIDs, passwords and other properties as they have on the current server. In fact I don't even know the passwords for the logins created by our Sage accounting package - apparently they are generated by the setup using a number of ingredients unique to each installation. I did some Googling and fount this KB article: http://support.microsoft.com/kb/918992/, which more or less did the trick. It produces a set of CREATE LOGIN statements with the SIDs and hashed passwords. But it didn't include the default language, which can subtly or dramatically alter the behaviour of date-related SQL. So I added that bit and you can help yourself here.

• How to Install Nvidia Drivers

  - by Richard Rodriguez

  I just ordered the Nvidia GTX 560 card, which should arrive tomorrow. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu (10.10), or should I install the driver from the nvidia site? NOTE - The methods to install explained here apply to all Nvidia, Ati & Intel video cards The latest driver available at the nvidia site: LINUX X64 (AMD64/EM64T) DISPLAY DRIVER Version: 280.13 Certified Release Date: 2011.08.01 Operating System: Linux 64-bit Language: English (U.S.) File Size: 52.4 MB I should point out that I don't need the card to unleash its full potential in Ubuntu (I have Windows for gaming, other HDD), I just need it to work properly, that meaning the power saving should work (I don't want the card to overheat for no reason), also I would like the fans to work at proper speeds, etc. So which driver is the best for me?

• Read only array, deep copy or retrieve copies one by one? (Performance and Memory)

  - by Arthur Wulf White

  In a garbage collection based system, what is the most effective way to handle a read only array if such a structure does not exist natively in the language. Is it better to return a copy of an array or allow other classes to retrieve copies of the objects stored in the array one by one? @JustinSkiles: It is not very broad. It is performance related and can actually be answered specifically for two general cases. You only need very few items: in this situation it's more effective to retrieve copies of the objects one by one. You wish to iterate over 30% or more objects. In this cases it is superior to retrieve all the array at once. This saves on functions calls. Function calls are very expansive when compared to reading directly from an array. A good specific answer could include performance, reading from an array and reading indirectly through a function. It is a simple performance related question.

• In this slow Job Market, I have no choice to take a Job that uses VB.NET and is going to use C#. Advice?

  - by Xaisoft

  I really don't want to do VB.NET, but I need a Job and I need a Job Fast. The two positions I am looking at both have existing apps in VB.NET, but are looking to convert them to C# and do new development in C#, but as well all know, sometimes this doesn't happen for a while and you get stuck with the main language. My background is in C# and after looking at VB.NET, my head is hurting. Any advice as I tackle a Job like this. As I said, I preferably want stick with C#, but today, one may have no choice, so I have to just take what I get. I am looking for advice on this for those who have experienced it, are experiencing it, and those who have not.

• Is there any text editor for windows which can save files with code highlight for viewing

  - by user1713836

  I want some software for Windows where I can save code snippets and other daily usable commands in one file. Everyday I find some small code snippets which I want to save in a single file. Just like we have code snippet savers online, I want something offline on Windows, basically with all the features Microsoft Word has, but with code highlight. It should be lightweight like Notepad++. I mean if I select the code and then press some button, it should change the color according to the language. Currently I use Notepad++, but in it, I can't select small code snippets on one page. It either highlights the entire file or nothing.

• How to shorten brain context switch delay when need to use new technology\framework?

  - by gasan

  The problem is when I have to deal with a new framework\library\language it completely slows my work process, at first it's kind of shock, you're sitting on your place about a day doing nothing surfing the net, because you simply can't do anything even read docs, then, on the second day I realize that I definitely should do something and starting read about it, then I realize that I don't understand it, then I'm reading until I got feeling that I should show some results immediately and then I'm writing the code quite fast and the job doesn't seem to be difficult. Then job is done and I won't probably return to that technology\framework for a month or a year or never at all. And I will almost certainly forget almost everything about it after a month. To illustrate by checkpoints I experience: shock, long studying times, work with the new tech briefly, never use it afterwards, then I completely forget it. So what would be the solution here?

• Is functional programming a superset of object oriented?

  - by Jimmy Hoffa

  The more functional programming I do, the more I feel like it adds an extra layer of abstraction that seems like how an onion's layer is- all encompassing of the previous layers. I don't know if this is true so going off the OOP principles I've worked with for years, can anyone explain how functional does or doesn't accurately depict any of them: Encapsulation, Abstraction, Inheritance, Polymorphism I think we can all say, yes it has encapsulation via tuples, or do tuples count technically as fact of "functional programming" or are they just a utility of the language? I know Haskell can meet the "interfaces" requirement, but again not certain if it's method is a fact of functional? I'm guessing that the fact that functors have a mathematical basis you could say those are a definite built in expectation of functional, perhaps? Please, detail how you think functional does or does not fulfill the 4 principles of OOP.

• How does the GPL static vs. dynamic linking rule apply to interpreted languages?

  - by ekolis

  In my understanding, the GPL prohibits static linking from non-GPL code to GPL code, but permits dynamic linking from non-GPL code to GPL code. So which is it when the code in question is not linked at all because the code is written in an interpreted language (e.g. Perl)? It would seem to be too easy to exploit the rule if it was considered dynamic linking, but on the other hand, it would also seem to be impossible to legally reference GPL code from non-GPL code if it was considered static! Compiled languages at least have a distinction between static and dynamic linking, but when all "linking" is just running scripts, it's impossible to tell what the intent is without an explicit license! Or is my understanding of this issue incorrect, rendering the question moot? I've also heard of a "classpath exception" which involves dynamic linking; is that not part of the GPL but instead something that can be added on to it, so dynamic linking is only allowed when the license includes this exception?

• Can non-IT people learn and take advantage of regular expressions? [closed]

  - by user1598390

  Often times, not-IT people has to deal with massive text data, clean it, filter it, modify it. Often times normal office tools like Excel lack the tools to make complex search and replace operations on text. Could this people benefit from regexps ? Can regexp be taught to them ? Are regular expressions the exclusive domain of programmers and unix/linux technicians ? Can they be learned by non-IT people, given regexps are not a programming language? Is this a valid or achievable goal to make some users regexp-literate through appopriate training ? Have you have any experiences on this issue? and if so, have it been successful ?

• 2D object-aligned bounding-box intersection test

  - by AshleysBrain

  Hi all, I have two object-aligned bounding boxes (i.e. not axis aligned, they rotate with the object). I'd like to know if two object-aligned boxes overlap. (Edit: note - I'm using an axis-aligned bounding box test to quickly discard distant objects, so it doesn't matter if the quad routine is a little slower.) My boxes are stored as four x,y points. I've searched around for answers, but I can't make sense of the variable names and algorithms in examples to apply them to my particular case. Can someone help show me how this would be done, in a clear and simple way? Thanks. (The particular language isn't important, C-style pseudo code is OK.)

• What program should i use for Ludum Dare?

  - by mFontoura

  I want to participate for the first time on Ludum Dare, but i'm not confortable yet with a language to pick one for making a game on a weekend. So i was looking for a program 'gamemaker' style, just to make something for LD. I was going for Construct 2, but i use Linux and they don't have a linux version. So the alternative i use is Stencyl, witch is great and probably is what i'm going to use. However, i wanted to know if there is something similar and better for Linux. Also, if i get a computer with Win8, is it worth the trouble for Construct 2?

• What is history and concept of code annotation?

  - by Eonil

  C# and Java has code attribute and code annotation. I don't know about other languages, but I know the code annotation feature is used to expand language itself. I knew what it is, but I want to know how it developed over time. I want to know its history. How it demanded and how it implemented. Is this possible to implement this in kind of concept on LISP, Smalltalk or C++? And is there a general term to call the concept of annotation?

• Object-Oriented equivalent of LISP's progn function?

  - by Archer

  I'm currently writing a LISP parser that iterates through some AutoLISP code and does its best to make it a little easier to read (changing prefix notation to infix notation, changing setq assignments to "=" assignments, etc.) for those that aren't used to LISP code/only learned object oriented programming. While writing commands that LISP uses to add to a "library" of LISP commands, I came across the LISP command "progn". The only problem is that it looks like progn is simply executing code in a specific order and sometimes (not usually) assigning the last value to a variable. Am I incorrect in assuming that for translating progn to object-oriented understanding that I can simply forgo the progn function and print the statements that it contains? If not, what would be a good equivalent for progn in an object-oriented language?

• When would I use pseudocode instead of flowchart?

  - by user1276078

  I'm a student working with various techniques of programming, and I've come across pseudocode and flowchart. I know that these are both used in order to think through the problem before actually programming, but I have a few questions with this. When would I use pseudocode to plan out and when would I use flowcharts? Or is it better to do both before actually programming. Particularly for a small arcade sort of game in JAVA since that is my next project. I've noticed that pseudocode is very similar to the actual code rather than flowcharts. Would this make pseudocoding better because you essentially copy/paste the pseudocode into your program (of course, you have to change it to fit the language. I understand that part). Is it practical to use both of these while programming? Particularly the same game mentioned earlier. Thanks.
