• graphical interface when using assembly language

  - by Hellbent

  Im looking to use assembly language to make a great game, not just an average game but a really great game. I want to learn a framework to use in assembly. I know thats not possible without learning the framework in c first. So im thinking of learning sdl in c and then learn, teach myself, how to interpret the program and run it as assembly language code which shouldnt be that hard. Then i will have a window and some graphics routines to display the game while using assembly to code everything in. I need to spend some time learning sdl and then some more time learning how to code all those statements using assembly while calling c functions and knowing what registers returned calls use and what they leave etc. My question is , Is this a good way to go or is there something better to get a graphical window display using assembly language? Regards HellBent

• Learn a language bottom-up or top-down?

  - by Hanno Fietz

  When starting the first project in a new language, you have basically two approaches to learning. Either you do a quick Google search, pull together the most popular frameworks and libraries and work your way from their tutorials towards what you want to achieve (top-down). Or you start with the language basics and the standard library and by and by replace your own simple components with more sophisticated third-party components once you know what you're searching for (bottom-up). Now I'm about to embark on my first serious Javascript project. There's probably as much to know about the language as there is about jQuery, ExtJS and whathaveyou, and I'm trying to decide what to focus on.

• Why Java as a First Language?

  - by dsimcha

  Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

• best programming language for a web based game?

  - by Adam Geisweit

  what programming language would be best for making a web based game to be played in a browser, and where would i be able to find tutorials on how to use the language? i have looked up silverlight in xna (because that was what i was most fluent with), but it made my projects unusable for a month until i got all of silverlight off my computer. i have looked at java and javascript, but i have found no suitable places where i can learn to create games on either of these, just the basics of the language. does anyone have any advice on this?

• A good language for c# dev to expand his mind [closed]

  - by Jan Kratochvil

  I have some free time on my hands and I was thinking about learning a new language. I do not plan to use it in my day-to-day job, but I rather want to expand my way of thinking to get a better sense where the dev world is heading from a language perspective and to don't get stuck in my way when programming by rather try new approaches. I was thinking either a functional language, like Haskell or F# (which is a bit more 'pragmatic from a .NET dev standpoint) or something dynamic (like Python, that in my oppinion has nicer syntax than Ruby). What can you recommend that is enjoyable, at least a bit practical, but most of all, new (from a c# dev perspective). I appreciate any answers.

• How is it possible to write the compiler of a programming language with that language itself [closed]

  - by tugberk

  Possible Duplicate: How could the first C++ compiler be written in C++? You probably heard that Microsoft released a new language called TypeScript which is a the typed superset of JavaScript. The most interesting thing that makes me wonder is the fact that its compiler writen in TypeScript itself. Call me ignorant but I really couldn't figure out in my head how that is possible. This is just like chicken and egg problem in my head because there is no compiler to compile TypeScript's compiler in the first place. How is it possible to write a compiler of the compiler of a programming language with that language?

• Choosing a new programming language to learn [on hold]

  - by Xelom

  I'm a Microsoft Stack(ASP.NET, C#) developer. Mainly, I develop server side software, windows services, restful apis etc. My client side interaction is really really low. So aside from C# I want to learn a new language. Time is precious and I want to give my focus to a language which have a future. My language list is: Scala (Powerful usage in Twitter) Go (Getting popular and channels are pretty awesome) Erlang (Stable server side programs. Used at Whatsapp) You can give advice for the above or you can give me a better option. My only exception is Objective-C. I don't want to get in that one. Thanks

• Criteria for a language to be considered "object oriented"

  - by nist

  I had a discussion about OO programming today and by browsing the internet I found a lot of different specifications for object oriented languages. What are the requirements for a language to be object oriented? For myself an object oriented language must have classes, inheritance and encapsulation. Is C an object oriented language just because you can use structs and program with an object oriented design? Why/ why not? Are there any good sites/articles about this? And please, no Wikipedia links because I've already been there.

• Fast language for problem solving? [closed]

  - by Friend of Kim

  I learned PHP to make websites. After some years I've started using programming for solving what is difficult tasks for my level. Now I want to make a program that solves equations. (I want to write it myself, not use an API. Because I'm doing this for the sake of the challenge, not for the result..) Because of this, I'm going to learn a new and faster/better language. It's going to be C++, Java, Python or C#. What are the benefits of each language, and which language is best for speed compared to speed of writing and readability? Using C would be lightning fast, but the lack of OO is making for more complex code and reduces the readability, for example..

• Knowledge of a Language vs. Games in Portfolio

  - by RedShft

  How important is the knowledge of a language versus the games that you have developed in your portfolio? To be more specific. Personally, I dislike C++ for several reason(mainly due to it's complexity, and pointers, and I prefer D as my language of choice thus far. Due to this, I've written two games in D instead of C++ that are my personal projects. Am I wasting my time with D? Should I start using C++ again? For reference, I have 6 months of experience in C++. It's the first language I learned. I have messed around with SDL/SFML and a bit of Direct3D with C++ as well. Even though I like D, i'd rather not waste my time learning it, if it in no way will help me get a job in the gaming industry.

• If Html File Has No Ending "/tr" Tag OR "/td" Tag Then HTML Agility Pack Does Not Read That Informat

  - by Harikrishna

  I am using HTML Agility Pack to parse html content. I am using parsing to extract table information. It works. But if there is no ending "/tr" tag or "/td" tag then it does not parse that information perfectly.(in which there is no ending tr tag or td tag.) Like <TABLE border=0><TBODY><TR height=20><TD class=xl27boL noWrap width="7%">01890345&nbsp;</TD> <TD class=xl27boL noWrap width="4%">1416</TD> <TD class=xl27boL noWrap width="7%">kjlkjkls&nbsp;</TD><TD class=xl27boL noWrap width="4%">14:01:57&nbsp;</TD> <TD class=xl27boL noWrap align=left width="15%">Football</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">50&nbsp;</TD> <TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boRLnoWrap align=right width="8%">249612.64&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">4997.2500</TD><TD class=xl27boL noWrap align=right width="7%">249862.50&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">249.86</TD><TD class=xl27boL noWrap align=right width="5%">4992.2528</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD><TD class=xl27boL noWrap align=right width="5%">&nbsp;</TD> <TD class=xl27boRL noWrap align=right width="8%">249612.64&nbsp;</TD> </table> So for that what should I do ?

• How can I change the UI language of QT Creator 1.3.1?

  - by simon

  I just downloaded and installed QT Creator 1.3.1 on my english Windows 7 system from the english download site at http://qt.nokia.com/downloads Apparently, however, the UI of QT Creator is in German language, although the help files are in English. From the FAQ at http://www.qt.gitorious.org/qt-creator/pages/FrequentlyAskedQuestions I found the answer Qt Creator uses the language setting of the system it runs on. On Linux systems you can also override that language by setting the LANG environment variable prior to starting Qt Creator, e.g. on the command line LANG=de ./qtcreator will run Qt Creator with german interface. This, however, is apparently not correct, as I have an English Windows, and as system locale I have "English (United Kingdom)" set. Possibly QT Creator interprets mistakenly the Windows settings for "current location", which I have set to "Germany" to mean that German would also be my language. However, changing that value had apparently no effect (maybe it should have been done before installing QT Creator). Is there any way to change the UI language of QT creator to english after installing it, preferrably without adjusting global system settings?

• Theory of Computation - Showing that a language is regular..

  - by Tony

  I'm reviewing some notes for my course on Theory of Computation and I'm a little bit stuck on showing the following statement and I was hoping somebody could help me out with an explanation :) Let A be a regular language. The language B = {ab | a exists in A and b does not exist in A*} Why is B a regular language? Some points are obvious to me. If b is simply a constant string, this is trivial. Since we know a is in A and b is a string, regular languages are closed under union, so unioning the language that accepts these two strings is obviously regular. I'm not sure that b is constant, however. Maybe it is, and if so, then this isn't really an issue. I'm having a hard time making sense of it. Thanks!

• What kind of knowledge do you need to invent a new programming language?

  - by systempuntoout

  I just finished to read "Coders at works", a brilliant book by Peter Seibel with 15 interviews to some of the most interesting computer programmers alive today. Well, many of the interviewees have (co)invented\implemented a new programming language. Some examples: Joe Armstrong: Inventor of Erlang L. Peter Deutsch: implementer of Smalltalk-80 Brendan Eich: Inventor of JavaScript Dan Ingalls: Smalltalk implementor and designer Simon Peyton Jones: Coinventor of Haskell Guy Steele: Coinventor of Scheme Is out of any doubt that their minds have something special and unreachable, and i'm not crazy to think i will ever able to create a new language; i'm just interested in this topic. So, imagine a funny\grotesque scenario where your crazy boss one day will come to your desk to say "i want a new programming language with my name on it..take the time you need and do it", which is the right approach to studying this fascinating\intimidating\magic topic? What kind of knowledge do you need to model, design and implement a brand new programming language?

• Why can't we have a single programming Language ? [closed]

  - by Kiran

  I am no expert in Programming Languages. But whenever I change the project, I am faced with Herculean challenge of learning the new programming language which takes weeks to master if not months.. With the previous experience of programming in different languages, I believe it takes few months of continuous programming to understand the amazing features the prog.language has to offer and to exploit. It makes me wonder, why cannot we have a single programming language which boasts all the amazing features from the existing programming language and make it mandatory for all the programmers to learn it.

• How is a new programming language actually formed/created ?

  - by hory.incpp

  Fortran-Algol-Cpl-Bcpl-C-C++-Java ..... Seems like every language is built upon an ancestor language. My question : New languages extend parent ones or there is some kind of a trick? e.g. System.out.print() in Java ; is it actually printf() in C, and so on (printf is actually .. in Cpl)? If so, doesn't this make every further language be slower and need more memory? What separates a new language from a framework?

• What would you suggest as a high school first language?

  - by ldigas

  Edit by OA: After reading some answers I'll just update the question a little. At first I put it a little bluntly, but some of those gave me some good arguments which have to be taken into consideration while making a stand on this one. (these are mostly picked up from comments and answers below). A few things to take into account: to many pupils this is a first programming language - at this stage most of them have trouble grasping a difference between data types, variable passing, ... and whatnot, less alone pointers and similar 'low level stuff' :) they will all have to pass this to get into next grade (well, big majority of them anyway) not all of them have computers at home, not all of them are willing to learn this, less alone interested in - so the concepts have to be taught on a finite time scale in school hours (as well as practice on computers) free literature is a bonus - the teacher will make some scripts and handaways, but still ... I wouldn't like to bear the parents with the burden of buying expensive literature (also, english is not a native language here ... and although they are all learning it, their ability to read it fluently is somewhat questionable) somebody gave an argument - "a language which does not get in the way of ideas" - good one accessibility on different platforms in not expecially important at this point - although most of the suggested ones are available on win as well as linux - not many macs in this part of europe (their prices are sky high for anything but specialised usage) I will check what are the licencing issues on ms express editions about using it massively in high schools for purposes like this - if someone has any info about this, please, do not be shy with it :) A friend of mine, informatics teacher - in EU it comes as something as junior cs teacher, in a local high school asked me what I thought about what should be the first language pupils should be taught? It is a technical school (a little more oriented towards mathematics than the gymnasium, but not computer oriented totally). So I'm asking you - what do you think should be the first language pupils are exposed to in highschool? They have been teaching Pascal so far, but she's not sure that's a good course. She thought about switching to C (which I resented; considering not all pupils have interests in programming, to start with, and should be taught something higher level since they are just gripping the idea of a loop and such ... for a start), I suggested python or ruby (preferably py since it handles all paradigms). What is your opinion on this one? I looked, but didn't find a similar question on SO, so if there is one, please just point me towards it. Edit: The assumption is that none of the pupils have been exposed to any programming in junior school. See also: What is the best way to teach young kids some basic programming concepts?

• How important is the programming language when you choose a new job?

  - by Luhmann

  We are currently hiring at the company where I work, and here the codebase is in VB.Net. We are worried that we miss out on a lot of brilliant programmers, who would never ever consider working with VB.Net. My own background is Java and C#, and I was somewhat sceptical as to whether it would work out with VB, as - to be honest - i didn't care much for VB. After a month or so, I was completely fluent in VB, and a few months later i discovered to my surprise, that I actually like VB. I still code my free time projects in C# and Boo though. So my question is firstly, how important is language for you, when you choose a new programming job? Lets say if its a great company, salary is good, and generally an attractive work-place. Would you say no to the perfect job, if the language wasn't your preferred dialect? VB or C# is one thing, but how about Java or C# etc. Secondly if the best developers won't join your company because of your language or platform, would you consider changing, to get the right people?

• Can any language potentially be used to create any program?

  - by Matt

  I've heard that given a programmer with enough time and skill in any particular language and enough lines of code, then any program could be created with any given language. I know its certainly not going to be cost-efficient, for instance, to rewrite Adobe Photoshop in BASIC, but could a good enough and patient enough programmer potentially create any program in any language?

• In hindsight, is basing XAML on XML a mistake or a good approach?

  - by romkyns

  XAML is essentially a subset of XML. One of the main benefits of basing XAML on XML is said to be that it can be parsed with existing tools. And it can, to a large degree, although the (syntactically non-trivial) attribute values will stay in text form and require further parsing. There are two major alternatives to describing a GUI in an XML-derived language. One is to do what WinForms did, and describe it in real code. There are numerous problems with this, though it’s not completely advantage-free (a question to compare XAML to this approach). The other major alternative is to design a completely new syntax specifically tailored for the task at hand. This is generally known as a domain-specific language. So, in hindsight, and as a lesson for the future generations, was it a good idea to base XAML on XML, or would it have been better as a custom-designed domain-specific language? If we were designing an even better UI framework, should we pick XML or a custom DSL? Since it’s much easier to think positively about the status quo, especially one that is quite liked by the community, I’ll give some example reasons for why building on top of XML might be considered a mistake. Basing a language off XML has one thing going for it: it’s much easier to parse (the core parser is already available), requires much, much less design work, and alternative parsers are also much easier to write for 3rd party developers. But the resulting language can be unsatisfying in various ways. It is rather verbose. If you change the type of something, you need to change it in the closing tag. It has very poor support for comments; it’s impossible to comment out an attribute. There are limitations placed on the content of attributes by XML. The markup extensions have to be built "on top" of the XML syntax, not integrated deeply and nicely into it. And, my personal favourite, if you set something via an attribute, you use completely different syntax than if you set the exact same thing as a content property. It’s also said that since everyone knows XML, XAML requires less learning. Strictly speaking this is true, but learning the syntax is a tiny fraction of the time spent learning a new UI framework; it’s the framework’s concepts that make the curve steep. Besides, the idiosyncracies of an XML-based language might actually add to the "needs learning" basket. Are these disadvantages outweighted by the ease of parsing? Should the next cool framework continue the tradition, or invest the time to design an awesome DSL that can’t be parsed by existing tools and whose syntax needs to be learned by everyone? P.S. Not everyone confuses XAML and WPF, but some do. XAML is the XML-like thing. WPF is the framework with support for bindings, theming, hardware acceleration and a whole lot of other cool stuff.

• Language Club – Battle of the Dynamic Languages

  - by Ben Griswold

  After dedicating the last eight weeks to learning Ruby, it’s time to move onto another language.  I really dig Ruby.  I really enjoy its dynamism and expressiveness and always-openness and it’s been the highlight of our coding club for me so far. But that’s just my take on the language.  I know a lot of coders who’s stomachs turn with the mere thought of Ruby.  They say it’s Ruby’s openness which has them feeling uneasy.  I’d say “write a bunch of tests and get over it,” but I figure there must be more to it than always open classes and possible method collisions. Yes, there’s something else to it alright. The folks who didn’t fall head over heals for Ruby are already in love with Python.  You might remember that Python was the first language we tackled in our coding club.  My time with Python was okay but it didn’t feel as natural to me as Ruby.  But let’s say we started with Ruby and then moved onto Python.  Would I see Python in a different light right now.  Might I even prefer Python over Ruby?  I suppose it’s possible but it’s pretty tough to test that theory – unless we visit Python for a second time. That’s right. The language club is going to focus on Python again and in my attempt to learn Python – yet again – in the open, I’ll be posting my solutions here just as I did for Ruby.  We don’t always have second chances so I going about this relearning with two primary goals in mind:  First, I’m going to use IronPython and the IronPython tools which provide a Python code editor, a file-based project system, and an interactive Python interpreter, all inside Visual Studio 2010.  As a note, the IronPython tools are now part of the main IronPython installer which is Version 2.7 Alpha 1 (not the latest stable version, 2.6.1) and I’d be crazy not to use them.  Second, I’d like to make sure I’m still learning Python without a complete MS skew so I’m going to run my code through Eclipse using the PyDev plugin as well.  Heck, I might use IDLE too. I already have this setup on my machine so it’s no big deal. Okay, that’s it for now.  I worked on the first ten Euler problems last night and the solutions will be posted shortly. Wish me luck.

• Is sticking to one language a good practice?

  - by Ans

  I'm developing a pipeline for processing text that will go into production. The question I keep asking myself is: should I stick to one language when looking for a tool to do a particular task (e.g. NLTK, PDFMiner, CLD, CRFsuite, etc.)? Or is it OK to mix and match looking for the best tool regardless of what language it's written in (e.g. OpenNLP, ParsCit, poppler, CFR++, etc.) and warp my code around them?
