• Using RTL languages with MS Office in Wine 1.4

  - by saeed hardan

  I've installed MS Office 2007 in Ubuntu 12.04 using Wine 1.4 with no problems, and it works fine with the English Language. However, I need to use it to work with Arabic and Hebrew, and it doesn't work when I switch to a Hebrew or Arabic keyboard. The typing gets reversed. I saw an earlier post for something similar, but it is closed and I think it was for the earlier Wine 1.3. Supposedly Wine 1.4 has added RTL -- is there a way to get it working?

• Problem with bash scripting

  - by eple

  Hi. I terrible with bash scripting, and need some help with the following: #!/bin/bash if [ -e Pretty* ];then ncftpput -R -DD -v -u xbmc -p xbmc 192.168.1.100 /home/xbmc/TV/Pretty_Little_Liars/ Pretty* else echo "No new folders" fi find -depth -type d -empty -exec rmdir {} \; Problem here is the ncftpput line.. if I just do a simple [ echo "working" ] instead, everything is OK, but when I try the ncftpput-line it just gives me [ line 5: [: too many arguments ] the ncftpput command alone works fine.. Any ideas?

• Programming languages similar to ActionScript 3 / EcmaScript based

  - by Juanlu001

  I almost learned programming and OOP basic concepts with ActionScript 3 on the Flash Platform years ago. Some time has passed since then; I'm not a professional programmer, but I have written code in PHP, Fortran, and now Python. But, lately, I have missed ActionScript 3 OOP implementation, static typing and, I confess, curly braces. As Flash platform is slowly dying nowadays, I'm looking for an Open Sourced programming language similar to ActionScript 3. I've read about Java, which is the most similar one I found, but actually is the only one it doesn't interest me (I started to hate it after bad experiences with web applets). Any ideas? Edit: Added EcmaScript to the title and the tags; I think that is what I am looking for.

• XSF-FO intellisense and national languages with Apache FOP

  - by Lukasz Kurylo

  Some time ago I showed how to get an intellisense and how to configure the FO.NET to acquire national characters inside the generated pdf files. Due to the limitations that I mensioned in my previous post, I started playing with the Apache FOP. In this post I want to show, how to acquire the same result as I showed in the two posts related to FO.NET.   Intellisense   To get the intellisense from the XSL-FO templates set the xsi:schemaLocation the same way I showed it in this post. The only diffrence to FO.NET is that, during generating the document by the code I showed last time we will get an exception:   org.apache.fop.fo.ValidationException: Invalid property encountered on "fo:root": xsi:schemaLocation (See position 6:11)   Fortunatelly there is a very easy way to resolve this without removing the entire attribute along with the intellisense. Add to the FopFactory the ignoreNamespace by:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.ignoreNamespace(http://www.w3.org/2001/XMLSchema-instance);   Notice that, the url specified in this method this is a namespace for the xmlns:xsi namespace, not xsi.schemaLocation.   Fonts / national characters   This point is a little dfferent to acquire, but not more complicated that it was with FO.NET. To set the fonts in Apache FOP 1.0, we need a configuration file. A sample one can be get from the directory where we unpacked the fop binaries, from conf subdirectory. There is a file called fop.xconf. We must copy this file to our solution. In the simplest way, in the <fonts> tag we can add  <auto-detect/>. Thanks to this, FOP will index all fonts available on the installed operating system. There probably should be no problem, if we have a http handler or a WCF Service on the server that serves the generated pdf documents. In this situation we can use all available fonts on this server.   To use this config file, we must set a path to it:   FopFactory fopFactory = FopFactory.newInstance(); fopFactory.setUserConfig(new File("fop.xconf"));

• Should one comment differently in functional languages

  - by Tom Squires

  I'm just getting started with functional programming and I'm wondering the correct way to comment my code. It seems a little redundant to comment a short function as the names and signature already should tell you everything you need to know. Commenting larger functions also seems a little redundant since they are generally comprised of smaller self-descriptive functions. What is the correct way to comment a functional program? Should I use the same approach as in iterative programming?

• Can we compare programming languages ergonomically?

  - by Nick Rosencrantz

  For instance, would Python be a more ergonomic programming language since it doesn't force you to make curly braces which requires the AltGr key. Also Python usually requires less code to achieve the same or am I being biased towards Python and PHP actually is an ergonomical and comfortable language despite forcing the programmer to use the AltGr key? Isn't forcing the programmer to use the AltGr key not very ergonomical?

• Are C or C++ The Only Viable Languages for a GC

  - by user95312

  Background I have just finished writing a compiler for a functional language compiling to the JVM as a learning project. However, since I'm just doing this to learn, I thought it might be interesting to write a native backend and a RTS for it. As I've been planning out what this new backend will look like, the one point I'm stumbling on is the garbage collector. I've implemented the compiler in Haskell. But I have no desire to write the GC in Haskell since, while it may be possible, it'd suck. Question I've looked at several FOSS garbage collectors prior to posting and most of them were implemented in good old ANSI C. Is this still the most accepted choice for writing a GC nowadays? I've seen that this site tends to frown upon questions with multiple answers so I hope this will make it more specific: If some startup was writing a professional grade gc today, are the only viable choice for them C or C++? It's my first question here so please comment and let me know if this question is ill-suited for for programmers.

• Programming Languages

  - by Shannon

  I realize this will be a very vague question, but please bear with me. I have a concept for an open-world game, hand to hand combat, with a fairly open storyline, but there is an issue. I'm not sure which programming language to use, as I'm fairly new to programming. I am considering c++, but I would like to hear your opinions on which language you believe would support this type of game most efficiently. Pros and cons would be appreciated.

• Languages and tools that are "portable" (work well from a USB storage drive) [closed]

  - by CodexArcanum

  I'm a huge fan of running programs from my portable hard drive: it means I always have my favorite tools no matter what computer I'm on. Sadly, development tools seem to be hard to get portable at times. I recently realized that the "portable" version of MinGW I was using off my USB drive was actually interfering with a locally installed version of MinGW, so sometimes even the tools you think are portable, aren't. So what are the best portable development tools that you've used? What runs well on a portable media, leaves the host machine clean, and generally makes moving around easier for you?

• Two different domain for specific languages pointing to one site

  - by user25599

  I developing a client's blog and he needs it to be bilingual (english and spanish). Now what he wants is that users can get to the content based on the domain e.g. Jhon enters www.domain.com and he gets the english version and Juan enters www.elsenordominio.com to get the spanish version. All content will be validated by php so the users and search engines only reads the domain related language. What do i need to use header re-direct or 301? is it bad for seo? will google will google penalize me? I hope you guys can help me and forgive me if my english is not good.

• Do input template languages exist?

  - by marczellm

  When I have to create some textual representation of data, I can use a template language, so that my code does not have to worry about the structure of the output file - I can sometimes even write code that's independent of whether the output is XML, LaTeX or any other plain text. A simple example: Template (in separate file): <someXmlTag> $variableName </someXmlTag> Code: Template(temstring).substitute(variableName="value") Result (written to output file): <someXmlTag> value </someXmlTag> I want to do the same, but in the opposite direction. I have XML or plain text or whatever files to input. I want to describe the input structure in a separate file that looks like the input but has these variable declarations in it, and I want to handle it with code that's independent of the structure. Is there a library for this concept? (We usually handle XML input by using an XML parser library to describe the input structure in program code, handle plaintext input by writing regexes in code, and don't handle LaTeX input because LaTeX can't really be parsed.)

• Is it worth it to learn an esoteric programming language?

  - by Thomas Owens

  Wikipedia: An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. This use of esoteric is meant to distinguish these languages from more popular programming languages. Some more popular languages may appear esoteric (in the usual sense of the word) to some, and though these could arguably be called "esoteric programming languages" too, this is not what is meant. I think it might be worth it, just to learn a new language and go through the process, although only if you don't have anything else to do (like a real project or learning a new real language). But what does the community think? Is there some value in these languages?

• Should a newcomer to Perl learn both Perl 5 and 6?

  - by M. Joanis

  Hello! I have started playing around with Perl 5 lately, and it seems very interesting. I would like to spend some time learning it more in depth when I can. My question, since Perl 6 is slowly taking place (I believe...) and is said to break backward compatibility, is this: am I better learning Perl 5 and then Perl 6, or is learning Perl 6 directly a better time investment according to you? If the changes from Perl 5 to 6 are making it hard to understand Perl 5, I should certainly start with Perl 5 to be able to read "old" scripts, then check Perl 6. There is also the "Perl 6 is not yet completely released" problem. I know there's an early adopter implementation for Perl 6, but if Perl 6 isn't officially released before some more years, I'll stick to 5 for now. I would certainly like some insight on this. Feel free to discuss related stuff. My interest in scripting languages is fairly new. Thanks!

• Web application development over C++ development..

  - by learnerforever

  Hi, I am CS undergrad and CS grad. In college I used to program in C/C++/java and have pretty much stuck to the same skill set in industry with 3 years experience. I like thinking,reading,applying logic etc, designing data structures, but I have little patience with debugging large C++ code. And having to deal with low level stuff like memory fault,memory corruption,compilation/linking issues. My confidence in programming is getting down due to this, but I like being in technical field. Does web application development like LAMP suit (Linux,apache,mysql,php),CSS,scripting (AMONG OTHER WEB DEVELOPMENT RELATED SKILLS) etc need lesser patience with debugging,and understanding of low level stuff, but your analysis/logical skills also get used? Also opportunities in web application development look more. Things like scalability, most of the stuff that Google does fascinates me, but for patience needed for dealing with C++ debugging. I make blunders while coding. How does the field look like outside C++? I am beginning to wonder if as a female, by moving to web application development, I can better manage work life balance. I have seen relatively lesser females in C++ than in Java/.net. Not very sure about web related stuff though. Also, what are the other hot technologies being used in web application development? lamp,css is something I know vaguely. Not in touch with keywords going on in this area. Please help!!.

• Why did object-oriented paradigms take so long to go mainstream?

  - by Earlz

  I read this question and it got me thinking about another fairly recent thing. Object oriented languages. I'm not sure when the first one was created, but why did it take so long before they became mainstream? C became vastly popular, but didn't become the object-oriented C++ for years(decades?) later No mainstream language before the 90s was object oriented Object oriented really seemed to take off with Java and C++ around the same time Now, my question, why did this take so long? Why wasn't C originally conceived as an object-oriented language? Taking a very small subset of C++ wouldn't have affected the core language a whole lot, so why was this idea not popular until the 90s?

• Differences between Dynamic Dispatch and Dynamic Binding

  - by Prog

  I've been looking on Google for a clear diffrentiation with examples but couldn't find any. I'm trying to understand the differences between Dynamic Dispatch and Dynamic Binding in Object Oriented languages. As far as I understand, Dynamic Dispatch is what happens when the concrete method invoked is decided at runtime, based on the concrete type. For example: public void doStuff(SuperType object){ object.act(); } SuperType has several subclasses. The concrete class of the object will only be known at runtime, and so the concrete act() implementation invoked will be decided at runtime. However, I'm not sure what Dynamic Binding means, and how it differs from Dynamic Dispatch. Please explain Dynamic Binding and how it's different from Dynamic Dispatch. Java examples would be welcome.

• How are Programing Language Designed?

  - by Anteater7171

  After doing a bit of programing, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

• Additional useful skill?

  - by Sergey

  Almost each language has some additional technology or skill or whatever which can work in a pair with it but still be something fresh. For example, Java + Flex. It's a good pair - those who learn Java and want something both useful and new may try Flex. What are "pairs" for the most popular languages(Java, C#, C++, etc.)? PS: Most people advise learning functional programming as an additional skill but this is very fuzzy. They talk about such abstract things as wide programming perspective and other things, but you can hardly say whether these functional skills will be really needed. Yeah, maybe some basics of it can be useful, but serious learning of LISP seems not perspective.

• Stack vs queue -based programming language efficiency [closed]

  - by Core Xii

  Suppose there are two programming languages; one where the only form of storage is one (preferred) or two (may be required for Turing-completeness) stacks, and another where the only form of storage is a single queue, with appropriate instructions in each to manipulate their respective storage to achieve Turing-completeness. Which one can more efficiently encode complex algorithms? Such that most given algorithms take less code to implement, less time to compute and less memory to do so. Also, how do they compare to a language with a traditional array (or unbounded tape, if you will) as storage?

• Learning a new language using broken unit tests

  - by Brian MacKay

  I was listening to a dot net rocks the other day where they mentioned, almost in passing, a really intriguing tool for learning new languages -- I think they were specifically talking about F#. It's a solution you open up and there are a bunch of broken unit tests. Fixing them walks you through the steps of learning the language. I want to check it out, but I was driving in my car and I have no idea what the name of the project is or which dot net rocks episode it was. Google hasn't helped much. Any idea?
