  • Pros and Cons of programming languages for XML & string manipulation

    - by aepheus
    I don't mean this to be opinionated. What are serious pros/cons of various server-side languages in regards to creating/modifying xml. I'm currently researching new platform/language direction and we deal with a lot of xml. We also do a lot of string manipulation, what advantages/disadvantages do different languages have in regards to string manipulation. I'm thinking along the lines of regular expression searching and replacing.

  • Git as mercurial client? Why no git-hg?

    - by aapeli
    This is a question that's been bothering me for a while. I've done my homework and checked stackoverflow and found at least these two topics about my question: Git for Mercurial like git-svn and Git interoperability with a Mercurial repository I've done some serious googling to solve this issue, but so far with no luck. I've also read the Git Internals book, and the Mercurial Definitive Behind the Scenes to try to figure this out. I'm still a bit puzzled why I haven't been able to find any suitable git-hg type of a tool. From my perspective hg-svn is one of the main features, why I've chosen to use git over mercurial also at work. It allows me to use a workflow I like, and nobody else needs to bother, if they don't care. I just don't see the point in using the intermediate hg repo to convert back and forth, as suggested in one of the chains. So anyway, from what I've read hg and git seem very similar in conceptual design. There are differences under the hood, but none of those should prevent creating a git client for hg. As it seems to me, remote tracking branches and octopus merges make git even more powerful than hg is. So, the real question, is there any real reason why git-hg does not exist (or at least is very hard to find)? Is there some animosity from git users (and developers) towards their hg counterparts that has caused the lack of the git-hg tool? Do any of you have any plans to develop something like this, and go public with it? I could volunteer (although with very feeble C-skills) to participate to get this done. I just don't possess the full knowledge to start this up myself. Could this be the tool to end all DVCS wars for good?

  • What's the "revised syntax" in OCaml?

    - by aneccodeal
    When people refer to the "revised syntax" in OCaml, do they mean that this will become a new syntax for the language, or is it just an alternative syntax created in CamlP4? If it's the former, then when does the "revised syntax" become the "official syntax" of OCaml?

  • Groovy / Scala / Java under the hood

    - by Jack
    I used Java for like 6-7 years, then some months ago I discovered Groovy and started to save a lot of typing.. then I wondered how certain things worked under the hood (because groovy performance is really poor) and understood that to give you dynamic typing every Groovy object is a MetaClass object that handles all the things that the JVM couldn't handle by itself. Of course this introduces a layer in the middle between what you write and what you execute that slows down everything. Then somedays ago I started getting some infos about Scala. How these two languages compare in their byte code translations? How much things they add to the normal structure that it would be obtained by plain Java code? I mean, Scala is static typed so wrapper of Java classes should be lighter, since many things are checked during compile time but I'm not sure about the real differences of what's going inside. (I'm not talking about the functional aspect of Scala compared to the other ones, that's a different thing) Can someone enlighten me? From WizardOfOdds it seems like that the only way to get less typing and same performance would be to write an intermediate translator that translates something in Java code (letting javac compile it) without alterating how things are executed, just adding synctatic sugar withour caring about other fallbacks of the language itself.

  • Are there any simple languages implemented using ANTLR or similar?

    - by etheros
    I'm trying to build a simple interpreted language for learning purposes. I've read countless theory and tutorials on ANTLR and JavaCC, but I can't figure out how to actually make it do something useful. I learn best by "taking something apart and putting it back together again", so, are there any working examples of simple languages implemented with the help of tools such as ANTLR, or similar? Something like the following might be nice: x = 1 if x == 1 print "true"

  • pure as3 benefits to compiling with flex4 instead of flex3?

    - by jedierikb
    If I have a pure as3 project that I have been compiling with flex3 from mxmlc, is there any reason to switch to using the mxmlc with flex4? I can use all of the flash 10 language features like Vector, 3D, etc., so that is not a reason to switch (or is there something I can't do?). But maybe there is a performance boost? Or is the exact same compiling tool and the flex code base is the only difference?

  • 2D Array values frequency

    - by Morano88
    If I have a 2D array that is arranged as follows : String X[][] = new String [][] {{"127.0.0.9", "60", "75000","UDP", "Good"}, {"127.0.0.8", "75", "75000","TCP", "Bad"}, {"127.0.0.9", "75", "70000","UDP", "Good"}, {"127.0.0.1", "", "70000","UDP", "Good"}, {"127.0.0.1", "75", "75000","TCP", "Bad"} }; I want to know the frequency of each value .. so I27.0.0.9 gets 2. How can I do a general solution for this ? In Java or any algorithm for any language ?

  • The future of programming, or what lies in the future in programming?

    - by prosseek
    I remember that a article that Microsoft uses formal verification to debug the Device Driver, and I also remember that Functional Programming removes much of the bug as it ensures stateless programming. And we all know about the multi-core. I beleive all of them are future direction of programming or programming language. Multi-core programming or parallel programming Software Formal Verification Functional Programming (as a mainstream?) What do you think? What will be the future of programming?

  • C precision of double: compiler dependent?

    - by yCalleecharan
    Hi,on my 32-bit machine (with an Intel T7700 duo core), I have 15 precision digits for both double and long double types for the C language. I compared the parameters LDBL_DIG for long doubles and DBL_DIG for doubles and they are both 15. I got these answers using MVS2008. I was wondering if these results can be compiler dependent or do they just depend on my processor? Thanks a lot...

  • Expression Too Complex In Access 2007

    - by Jazzepi
    When I try to run this query in Access through the ODBC interface into a MySQL database I get an "Expression too complex in query expression" error. The essential thing I'm trying to do is translate abbreviated names of languages into their full body English counterparts. I was curious if there was some way to "trick" access into thinking the expression is smaller with sub queries, or if someone else had a better idea of how to solve this problem. I thought about making a temporary table and doing a join on it, but that's not supported in Access SQL. Just as an FYI, the query worked fine until I added the big long IFF chain. I tested the query on a smaller IFF chain for three languages, and that wasn't an issue, so the problem definitely stems from the huge IFF chain (It's 26 deep). Also, I might be able to drop some of the options (like combining the different forms of Chinese or Portuguese) As a test, I was able to get the SQL query to work after paring it down to 14 IFF() statements, but that's a far cry from the 26 languages I'd like to represent. SELECT TOP 5 Count( * ) AS [Number of visits by language], IIf(login.lang="ar","Arabic",IIf(login.lang="bg","Bulgarian",IIf(login.lang="zh_CN","Chinese (Simplified Han)",IIf(login.lang="zh_TW","Chinese (Traditional Han)",IIf(login.lang="cs","Czech",IIf(login.lang="da","Danish",IIf(login.lang="de","German",IIf(login.lang="en_US","United States English",IIf(login.lang="en_GB","British English",IIf(login.lang="es","Spanish",IIf(login.lang="fr","French",IIf(login.lang="el","Greek",IIf(login.lang="it","Italian",IIf(login.lang="ko","Korean",IIf(login.lang="hu","Hungarian",IIf(login.lang="nl","Dutch",IIf(login.lang="pl","Polish",IIf(login.lang="pt_PT","European Portuguese",IIf(login.lang="pt_BR","Brazilian Portuguese",IIf(login.lang="ru","Russian",IIf(login.lang="sk","Slovak",IIf(login.lang="sl","Slovenian","IIf(login.lang="fi","Finnish",IIf(login.lang="sv","Swedish",IIf(login.lang="tr","Turkish","Unknown")))))))))))))))))))))))))) AS [Language] FROM login, reservations, reservation_users, schedules WHERE (reservations.start_date Between DATEDIFF('s','1970-01-01 00:00:00',[Starting Date in the Following Format YYYY/MM/DD]) And DATEDIFF('s','1970-01-01 00:00:00',[Ending Date in the Following Format YYYY/MM/DD])) And reservations.is_blackout=0 And reservation_users.memberid=login.memberid And reservation_users.resid=reservations.resid And reservation_users.invited=0 And reservations.scheduleid=schedules.scheduleid And scheduletitle=[Schedule Title] GROUP BY login.lang ORDER BY Count( * ) DESC; @ Michael Todd I completely agree. The list of languages should have been a table in the database and the login.lang should have been a FK into that table. Unfortunately this isn't how the database was written, and it's not really mine to modify. The languages are placed into the login.lang field by the PHP running on top of the database.

  • Programatically change cursor speed in windows

    - by Juan Manuel Formoso
    Since getting a satisfactory answer on SuperUser is very difficult, I want to rephrase this question and ask: Is there any way to programatically detect a mouse was plugged in the usb port, and change the cursor speed in windows (perhaps through an API)? I'd like to use C#, but I'm open to any language that can run on a windows 7 machine.

  • Why has anybody ever used COBOL?

    - by sarzl
    I know: You and me hate COBOL. I took a look at a lot of code examples and it didn't take me long to know why everybody tries to avoid it. So I really have no idea: Why was COBOL ever used? I mean: Hey - there was Fortran before it, and Fortran looks like a jesus-language compared to COBOL. This isn't argumentative but historical as I'm young and didn't even know about COBOL before 4 months.

  • Advice and resources for Apple iOS 4 development

    - by mlambie
    I'm looking for resources, screencasts, books, courses, sites and the like to assist with learning Objective-C with the intention of developing applications for Apple's iOS 4. My development team has access to Apple's development program, and is largely coming from a similar background: they're Comp Sci graduates that have experience with Ruby and web languages, but haven't written any C since university. Considering Apple's announcement regarding limited programming language support for developers, what's the current best avenue for learning Objective-C with the desire for developing iPad and iPhone applications?

  • HTML Types - Learning Order?

    - by Gabe
    I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML. But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on. So, which should I start with? In what order should I learn them? And, for that first language, where should I learn at?

  • Finding a small image in a bigger one

    - by tur1ng
    Given an image with a large dimension ( 1.000 x 1.000). What is a good approach to find a small image (e.g. 50 x 50) in the big one? The smaller image can be rotated and differ in the size, but only with a 1:1 ratio. It's not related to any programming language - I'm just interested in pattern recognition. Thank you.
