  • Why is Javascript used in MongoDB and CouchDB instead of other languages such as Java, C++?

    - by startup007
    I asked this question on SO but was suggested to try here. So here it goes: My understanding of Javascript so far has been that it is a client-side language that capture events and makes a web-page dynamic. But on reading the comparison between MongoDB and CouchDB I noticed that both are using Javascript. This makes me wonder the reason behind the choice of JavaScript over other conventional languages. I guess I am trying to understand the role of JavaScript and its advantages over other languages. Update: I am not asking about the languages / drivers supported by the two databases. The comparison says: Both CouchDB and MongoDB make use of Javascript. CouchDB uses Javascript extensively including in the building of views. MongoDB also supports running arbitrary javascript functions server-side and uses javascript for map/reduce operations. My lack of understanding pertains to why is Javascript being used at all for the backend work. Why is it preferred for building views in CouchDB, or for using map/reduce operations? Why C/C++ or Java were not used? What are the advantages in using Javascript for such back-end work?

  • Advice needed on how to start web programming? [closed]

    - by Recursion
    Possible Duplicate: Best approach to learning web programming I have resisted doing web programming for a while, but I have come to the realization that I need to learn it and may have resisted do to fear of the unknown. I am a regular applications and systems programmer with no real idea of how to even get started. I have tried to start a few times, rails, django, tornado, web.py, cherrypy, but always get discouraged and quit. The most web programming I have done was in HTML during 1995 for my geocities site. I have pretty decent experience with regular programming in C, Python, Assembly and Java. Just looking for a way to get started and get a good overview of the different technologies and frameworks. I am not doing this for a job or employment, just to learn.

  • Best programming aids for a quadriplegic programmer

    - by Peter Rowell
    Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

  • Hypercom P2100 pinpad programming

    - by Xience
    Hey guys, i have got a Hypercom P2100 pinpad that i need to incorporate in my POS app. I tried to access it through hyperterminal but didn't succeed. It is connected to my machine through a USB to Serial interface, could that be the source of problem. In addition, upon googling the programming samples that i could find just showed, at max, reading data on serial port but nothing on programming the pinpad itself. Any help is greatly appreciated.

    I'm just learning to program Dynamics AX 2009. So far I got the dev system running, I got some background about the architecture. Now I'm looking for some walkthrough-samples to learn more about programming in this system. Are there some samples available online? Can someone point me to some learning help? Maybe to some good AX-programming related blogs? How did you learn to program DAX9?

  • Suggestions for programming language and database for a high end database querying system (>50 milli

    - by mmdave
    These requirements are sketchy at the moment, but will appreciate any insights. We are exploring what would be required to build a system that can handle 50 database million queries a day - specifiically from the programming language and database choice Its not a typical website, but an API / database accessing through the internet. Speed is critical. The application will primarily receive these inputs (about a few kb each) and will have to address each of them via the database lookup. Only a few kb will be returned. The server will be run over https/ssl.

  • Maximum Method Name Length

    - by Josh
    Does anyone happen to know what the maximum length of a method name is in your programming language of choice? I was going to make this a C# specific question, but I think it would be nice to know across the spectrum. What are the factors involved as well: Does the language specification limit this? What does the compiler limit it to? Is it different on 32bit vs 64bit machines?

  • Which book for windows Shell programming?

    - by serefarikan
    I've been looking for a good book for windows shell programming, and the only one I could find is Visual C++ Windows Shell Programming by Dino Eposito: http://www.wintellect.com/BookInformation.aspx?ASIN=1861001843 It is an old book, and I'd like to know if you know of any good resources which could help. I need to develop a couple of windows explorer extensions, and apparently managed code is not recommended by Microsoft at least for some of these tasks. So I'm searching for a good resource for native development. Kind regards Seref

  • Reliable strtotime() result for different languages

    - by Maksee
    There was always a strange bug in Joomla when adding new article with back-end displayed with a language other than English (for me it's Russian). The field "Finish Publishing" started to be current date instead of "Never" equivalent in Russian. For a site in php4 finally found that strtotime function returns different results for arbitrary words. For "Never" it always -1 and joomla relies on this result in the JDate implementation. But in other case it sometimes returns a valid date. For russian translation of Never (???????) it is the case, but also for single "N" it is the case, so if one decided to change the string to some other he or she would face the same issue. So the code below <?php echo "Res:".strtotime("N")."<br>"; echo "Res:".strtotime("Nev")."<br>"; echo "Res:".strtotime("Neve")."<br>"; echo "Res:".strtotime("Never")."<br>"; ?> Outputs: Res:1271120400 Res:-1 Res:-1 Res:-1 So what are the solutions would be in this case? I would like not to write language-specific date.php handler, but to modify date method of JDate class, but what are language-neutral changes would be in order to detect invalid string. Thank you

  • The whole point of programming is creating abstractions

    - by Damien
    Hullo, this is Damien. I am new to programming and to StackOverflow community. Our professor once said that "the whole point of programming is creating abstractions." His explanation however went right over my head. Please explain the meaning of this sentence in simple words -- something that a noob like me can understand. Thank you!

  • Organizing a project that uses multiple languages?

    - by calid
    I am currently working on a project that has components in perl, .NET, C/C++, and Java. These components are inter-related, but are not tied to the same release schedule. Due to the very different build/testing environment requirements, lumping them all in to the same /bin /src /lib /etc /tests hierarchy is a bit unwieldy. What are some good organizational hierarchies to use in source control when dealing with a project of this nature? I am currently leaning towards each language having its own branch: repo/project1/perl/main/... repo/project1/.NET/main/... repo/project1/Java/main/... How would your recommended hierarchy change if they DID have a tied release schedule?

  • Must read books for a programming team leader

    - by takeshin
    As a programming team leader, which books do you recommend? Books about HR, good programming practices etc. I have recently seen PHP Team Development but it is not mind blowing for experienced developers. One of the best I can recommend is Microsoft Manual of Style for Technical Publications, which helped me a lot in improving the language and practices of documenting the code.

  • Catching typos in scripting languages

    - by Geo
    If your scripting language of choice doesn't have something like Perl's strict mode, how are you catching typos? Are you unit testing everything? Every constructor, every method? Is this the only way to go about it?
