  • The most mind-bending programming language?

    - by Xepoch
    From a reasonably common programming language, which do you find to be the most mind-bending? I have been listening to a lot of programming podcasts and taking some time to learn some new languages that are being considered upcoming, and important. I'm not necessarily talking about BrainFuck, but which language would you consider to be one that challenges the common programming paradigms? For me, I did some functional and logic (ex. Prolog) programming in the 90s, so can't say that I find anything special there. I am far from being an expert in it, but even today the most mind-bending programming language for me is Perl. Not because "Hello World" is hard to implement but rather there is so much lexical flexibility that some of the hardest solutions can be decomposed so poetically that I have to walk outside away from my terminal to clear my head. I'm not saying I'd likely sell a commercial software implementation, just that there is a distinct reason Perl is so (in)famous. Just look at the basic list of books on it. So, what is your mind-bending language that promotes your better programming and practices?

  • How to choose a server side language / framework

    - by pllee
    I am trying to come up with a list / ranking system on determining which server language to choose for a particular website. Assume that familiarity with a certain language is not important and the implementation can be done in any language. Here are some things that might be important but I am not sure how to rank them : Maintainability. Libraries. For example, Memcached and NoSql support right out the box would be really nice addition to a particular framework. 3rd party SDK's. For example, if I need Paypal on my site they openly provide SDK's for all senarios in Java, PHP and .Net. If I choose Django I would have to rely on 3rd party libraries that are don't support everything and are not officially maintained. Would that be dealbreaker for Django? Performance This one is tricky to put on a generic list because it can be a deal breaker but for many websites performance will not be an issue that the language/framework is responsible for. Cost (hosting, open source). edit - Any reason for the votes to close? I didn't see any duplicates mentioned and the question should not drum up a flame war.

  • NPE with logging while launching webstart on jre7 update 40

    - by atulsm
    My application was running fine until I upgraded my jre to 7u40. When my application is initializing, it's doing Logger.getLogger("ClassName"), and I'm getting the following exception. java.lang.ExceptionInInitializerError at java.util.logging.Logger.demandLogger(Unknown Source) at java.util.logging.Logger.getLogger(Unknown Source) at com.company.Application.Applet.<clinit>(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.javaws.Launcher.executeApplication(Unknown Source) at com.sun.javaws.Launcher.executeMainClass(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.NullPointerException at java.util.logging.Logger.setParent(Unknown Source) at java.util.logging.LogManager$6.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.doSetParent(Unknown Source) at java.util.logging.LogManager.access$1100(Unknown Source) at java.util.logging.LogManager$LogNode.walkAndSetParent(Unknown Source) at java.util.logging.LogManager$LoggerContext.addLocalLogger(Unknown Source) at java.util.logging.LogManager$LoggerContext.addLocalLogger(Unknown Source) at java.util.logging.LogManager.addLogger(Unknown Source) at java.util.logging.LogManager$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.util.logging.LogManager.<clinit>(Unknown Source) The exception is coming from this line: private static Logger logger = Logger.getLogger(Applet.class.getName()); Could it be because of any sideeffects with fix http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8017174 ? A workaround is to open the java control center and enable logging. This is a concern since by default "Enable Logging" is unchecked. If I select "Enable Logging", the application starts fine.

  • Python: Future as a major programming language?

    - by chrisw
    After reading some Python material and seeing some Python code a few years back I decided to give it a whirl. I decided to start with Python to solve the problems on Project Euler and was throughly impressed with the language. Since then I've went on to learn Django, and now use it primarily for my web applications. I would love to have a career programming in this language, however I fear the future of the language is currently in a state of uncertainness. With Google and other major companies embracing it there may be some hope, what are your thoughts on Python, do you see many job opportunities out there?

  • Which programming language for text editing?

    - by Ali
    I need a programming language for text editing and processing (replace, formatting, regex, string comparison, word processing, text analysis, etc). Which programming language is more powerful and has more functions for this purpose? Since I work PHP for my web projects, I currently use PHP; but the fact is that PHP is a scripting language for web applications, my current project is offline. I am curious if other programming languages such as Perl, Python, C, C++, Java, etc have more functionality for this purpose, and worth of shifting the project?

  • Are random packets normal?

    - by TheLQ
    About a month ago on one of my servers I started receiving random packets from IPs all over the world. So I did the smart thing and stopped putting off installing an IDS. This IDS is a ClearOS Gateway which comes with Snort and SnortSam. I enabled it, checked There is a total of 4 ports open, two of which forward to the server I'm talking about. These ports are 3724 and 8085, so they aren't going to be easily detected in a port scan. However checking some logs of this server I found that the attack is resuming. I found this ... Accepting connection from '75.166.155.122' [Auth] got unknown packet from '75.166.155.122' Accepting connection from '98.164.154.93' [Auth] got unknown packet from '98.164.154.93' Ping MySQL to keep connection alive Accepting connection from '70.241.195.129' [Auth] got unknown packet from '70.241.195.129' Accepting connection from '67.182.229.169' [Auth] got unknown packet from '67.182.229.169' Accepting connection from '69.137.140.38' [Auth] got unknown packet from '69.137.140.38' Accepting connection from '76.31.72.55' [Auth] got unknown packet from '76.31.72.55' Accepting connection from '97.88.139.39' [Auth] got unknown packet from '97.88.139.39' Accepting connection from '173.35.62.112' [Auth] got unknown packet from '173.35.62.112' Accepting connection from '187.15.10.73' [Auth] got unknown packet from '187.15.10.73' Accepting connection from '66.66.94.124' [Auth] got unknown packet from '66.66.94.124' Accepting connection from '75.159.219.124' [Auth] got unknown packet from '75.159.219.124' Accepting connection from '99.102.100.82' [Auth] got unknown packet from '99.102.100.82' Accepting connection from '24.128.240.45' [Auth] got unknown packet from '24.128.240.45' Accepting connection from '99.231.7.39' [Auth] got unknown packet from '99.231.7.39' Accepting connection from '206.255.79.56' [Auth] got unknown packet from '206.255.79.56' Accepting connection from '68.97.106.235' [Auth] got unknown packet from '68.97.106.235' Accepting connection from '69.134.67.251' [Auth] got unknown packet from '69.134.67.251' Accepting connection from '63.228.138.186' [Auth] got unknown packet from '63.228.138.186' Accepting connection from '184.39.146.193' [Auth] got unknown packet from '184.39.146.193' Accepting connection from '69.171.161.102' [Auth] got unknown packet from '69.171.161.102' Accepting connection from '76.0.47.228' [Auth] got unknown packet from '76.0.47.228' Ping MySQL to keep connection alive Accepting connection from '126.112.201.14' [Auth] got unknown packet from '126.112.201.14' Ping MySQL to keep connection alive Now that scares me. Why isn't Snort detecting this? How were they able to find this specific port? More importantly, what normally would these packets contain? Is this something I should be worried about? How can I stop this?

  • 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.

  • 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?

  • Encoding in Scene Builder

    - by Agafonova Victoria
    I generate an FXML file with Scene Builder. I need it to contain some cirillic text. When i edit this file with Scene Builder i can see normal cirillic letters (screen 1) After compileing and running my program with this FXML file, i'll see not cirillic letters, but some artefacts (screen 2) But, as you can see on the screen 3, its xml file encoding is UTF-8. Also, you can see there that it is saved in ANSI. I've tried to open it with other editors (default eclipse and sublime text 2) and they shoen wrong encoding either. (screen 4 and screen 5) At first i've tried to convert it from ansi to utf-8 (with notepad++). After that eclipse and sublime text 2 started display cirillic letters as they must be. But. Scene builder gave an error, when i've tried to open this file with it: Error loading file C:\eclipse\workspace\equification\src\main\java\ru\igs\ava\equification\test.fxml. C:\eclipse\workspace\equification\src\main\java\ru\igs\ava\equification\test.fxml:1: ParseError at [row,col]:[1,1] Message: Content is not allowed in prolog.

And, having this file in ANSI, changed its "artefacted" text to cirillic letters manually. Now i can see normal text when i run my program, but when i open this fixed file via Scene Builder, Scene Builder shows me some "artefacted" text (screen 7). So, how can i fix this situation?

  • Nginx virtual server only partially working with Java application

    - by MFB
    Final Cut Server is a Java application (made by Apple) which launches from a web page. I have Nginx in front of this web server (amongst others) and, whilst the web server can be browsed externally, the Java app fails to launch correctly and throws the errors below. Can anyone offer clues as to what additional config I many have to add to Nginx to get this working? My existing Nginx config: user xxxx; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 1024; # multi_accept on; } http { sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/conf/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; gzip on; gzip_disable "msie6"; server { server_name _; return 444; } upstream fcs-site { server 10.10.5.20:8080; } server { listen 80; server_name example.com 10.10.5.90; access_log /var/log/nginx/fcs_access.log; error_log /var/log/nginx/fcs_error.log; location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 60s; proxy_send_timeout 90s; proxy_read_timeout 90s; proxy_buffering off; proxy_temp_file_write_size 64k; proxy_pass http://fcs-site; proxy_redirect off; } } upstream myapp-site { server 127.0.0.1:6543; } server { listen 80; server_name otherexample.com www.otherexample.com; rewrite ^ https://$server_name$request_uri?

  • 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?
