  • How to convert int to char in JSP expression language?

    - by james.bunt
    I need to display incremented single characters to denote footnotes in a table of data in a JSP. In Java I would normally have a char variable and just increment it, or convert an int to a char by casting it (e.g. (char)(i + 97) to convert a 0-based index to a-z). I can't figure out how to do this in expression language short of writing my own JSTL function. Does anyone know how to convert an int to char in EL? Or how to increment a char variable in EL? Or possibly even a better technique to do what I'm trying to do in JSP/EL? Example of what I need to be able to produce: a mydata b myotherdata ... a first footnote b second footnote

  • How to make it easy for users to install my software? Does the programming language matter?

    - by lala
    I'm a beginner to intermediate programmer and I've learned some java and C#. I want to start thinking about making some simple programs that I can release to the world. Just some basic stuff like calendar software that will probably be free. Users want the install process to be quick and easy. To install a java program, I have to tell them to have java installed. To install a C# program, I have to tell them to have .NET installed. I'm worried this might put off some potential users who just want to double click an exe file, choose a directory and be pretty much done. So, I guess this is an either/or two part question: 1) Is there a programming language that makes it easier to set up an installer without requiring users to have other stuff installed? or: 2) Is there some way to set up an installer that checks the system to see if it has java/.NET/whatever, and then includes java/.Net/whatever in the installation if it's not already there?

  • Why does Chrome incorrectly determine page is in a different language and offer to translate?

    - by Sam
    The new Google Chrome auto-translation feature is tripping up on one page within one of our applications. Whenever we navigate to this particular page, Chrome tells us the page is in Danish and offers to translate. The page is in English, just like every other page in our app. This particular page is an internal testing page that has a few dozen form fields with English labels. I have no idea why Chrome thinks this page is Danish. Does anyone have insights into how this language detection feature works and how I can determine what is causing Chrome to think the page is in Danish?

  • How is thread synchronization implemented, at the assembly language level?

    - by Martin
    While I'm familiar with concurrent programming concepts such as mutexes and semaphores, I have never understood how they are implemented at the assembly language level. I imagine there being a set of memory "flags" saying: lock A is held by thread 1 lock B is held by thread 3 lock C is not held by any thread etc But how is access to these flags synchronized between threads? Something like this naive example would only create a race condition: mov edx, [myThreadId] wait: cmp [lock], 0 jne wait mov [lock], edx ; I wanted an exclusive lock but the above ; three instructions are not an atomic operation :(

  • Why can I not view foreign language characters in my mysql DB?

    - by Chris
    I am inserting the following characters into my DB: ?? / ?? This is the meta tag on the page that is inserting the characters: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> I have altered all the columns in my table that is holding the characters to be utf8_unicode_ci The foreign characters show up like so in the DB: 汉字 / 漢字 When I use a sql statement to display those foreign characters on a page, they display correctly again as: ?? / ?? I am guessing I have some setting that is not correct in my DB, since it stores it correctly, but does not display it correctly. What can i do to make the foreign language characters to display correctly in my DB?

  • Have different fallback language than the keys used in NSLocalizedString(@"Text aka. key",@"Descript

    - by Allisone
    I use everywhere NSLocalizedString(@"Text in deutsch",@"das Textfeld Text in deutsch") I have two Localizable.strings files. One for german and one for english. What I realized now is. If you have a german iPhone, you get the german text, if you have your iPhone set to english you get the english text. But if you have lets say french, then you would get the german text, too because I use german as the keys, right ? Is there a way to set english as fallback language instead of the german one used everywhere in my code ? (I have so many occurences of NSLocalizedString that it would be a pain to change the keys now everywhere (in code, in Localized.string.en and in Localized.string.de))

  • What language/API to use for a standalone live-input audio visualizer app?

    - by knuckfubuck
    I develop with Actionscript and was glad to see that AIR 2.0 was going to give access to mic input data. I planned to use this to create a visualizer set to the tempo of the incoming live audio. After doing a few days of google research it seems unlikely that it will be possible to analyze the data of the mic input in Flash/AIR. If anyone has ideas on how I can achieve this in AIR please let me know. (I'm open to workarounds.) That being said, I don't want to give up on the idea so I'm interested in suggestions for other language/API to use. My requirements for the app are: Run on OSX Two windows - one that can go fullscreen while the other(controller GUI) stays put Able to access live mic input data I've done reading on FFT and understand what needs to be done on the sound side so no need to help with that.

  • GUI designers! - got suggestions for a GUI modelling diagram language?

    - by naugtur
    Refering to this question I asked a while ago: UI functionality modeling languages It looks like there is no good-enough solution. I decided to develop one. (and prepare a set of elements for DIA or something) I'm sure it will require a good insight in peoples' experiences and problems in designing functionally complicated GUIs. I've got some ideas already, but I'd like to hear from You what You'd expect from a GUI functionality modelling language. Clarification: It's functionality modelling, so it's not about where I put a button. It's about objects that have some events binded, and the interface behaviour logic. If You think (just as I do) that UML is far from useful for such purposes - feel free to put Your expectations here. I'll try to meet them. ( not necessarily in person;) ) Remember - there is no such thing as a wrong answer to this question

  • Is there any way to create a dynamic list of strings (based on language) in XAML?

    - by Xin
    Just wondering if it is possible to dynamically create a list of strings in XAML based on language/culture? Say if user logs in as an English user it shows Client Name, Order Number... and if user logs in as a Polish user it shows Nazwa klienta, Numer zamówienia instead? I only know the hardcoded one like below: <System_Collections_Generic:List`1 x:Key="columnNameList"> <System:String>Client Name</System:String> <System:String>Order Number</System:String> <System:String>Date</System:String> </System_Collections_Generic:List`1>

  • Can PMD be customized to fully support a new language?

    - by tinny
    Can PMD be customized to fully support a new language, in a reasonable amount of time. I mean I know that technically almost anything can be done, but im wondering if this can be done in a reasonable amount of time? E.g. < 2 weeks This page mentions how to write a CPD parser http://pmd.sourceforge.net/cpd-parser-howto.html But is this just for copy / paste detection? Does writing a CPD parser give me full support of PMD in terms of rile sets?

  • Why do Java/C# edge out C++ as the recommended language to learn OOP on S.O?

    - by viksit
    I noticed after reading the answers/discussion to this question (What is the best language to learn OOP on?) - that more and more people are recommending C# or Java over C++ to learn OOP on. A simple term search on that answer page results in 10 hits for C++, 21 for C# and 27 for Java. Now, I understand that these 2 languages fix a lot of quirks and issues with C++, and looked up these resources that relate mostly to performance, JVM vs native implementation, systems focus vs applications, manual memory management vs automated et al. My question is - are there any fundamental differences in the OO capabilities of Java/C# vs C++? Or are the former recommended purely due to their generic ease of use/improvements over the latter? Thanks. PS, I'm aware of Java interface inheritance vs C++ multiple inheritance as a difference. I would consider that an implementational one rather than functional.

  • Must a Language that Implements Monads be Statically Typed?

    - by Morgan Cheng
    I am learning functional programming style. From this link http://channel9.msdn.com/shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads/, Brian Beckman gave a brilliant introduction about Monad. He mentioned that Monad is about composition of functions so as to address complexity. A Monad includes a unit function that transfers type T to an amplified type M(T); and a Bind function that, given function from T to M(U), transforms type M(T) to another type M(U). (U can be T, but is not necessarily). In my understanding, the language implementing monad should be type-checked statically. Otherwise, type errors cannot be found during compilation and "Complexity" is not controlled. Is my understanding correct?

  • How can I try a new language or framework without installing it?

    - by flamingLogos
    With so many languages and frameworks that exist, and with new ones appearing all the time, I don't have the time to download, install, and configure each one to evaluate it. In the past I've run across webapps that allow one to write or paste code into a window, and see the results in realtime in the browser, usually in a tutorial setting. What are your favorite sandbox sites for a given technology? Edit: @fretj provided the link to the excellent Google Code Playground (+1 upvote), but I thought that it was just for experimenting with Google's own apps (Search, Maps, Earth, Language, etc). But it turns out that it contains a few hidden gems: In addition to their apps, you can try out the many Javascript libraries that they host including jQuery, jQuery UI, MooTools, Dojo, and Prototype Scriptaculous. They're all hidden under the Libraries category in the "Pick an API" box. I overlooked the category because I thought it was for an app called Google Libraries. There's also a Javascript category for Javascript itself.

  • What programming language is used to design google algorithm?

    - by AKN
    It is known that google has best searching & indexing algorithm. The also have good relevancy. They are also quicker in getting down the latest results. All that's fine. What programming language (c, c++, java, etc...) & database (oracle, MySQL, etc...) they have used in achieving this. Since they have to manipulate with volume of data quickly and effectively. Though I'm not looking for their indepth architecture (if in case violates their company policies) an overview of all such things could be useful. Anybody please add you valuable suggestions and insight on this?

  • How are operating Systems created? Which language is chosen for coding?

    - by Nitesh Panchal
    Hello, How is a basic OS created? In which language do programmers code for OS? C or Assembly? or which? Also, Assembly has limited instruction set like mov etc. So how can anybody create OS in assembly? and even C has limited functionality. But it is said to be the mother of all languages. How can anybody create a full OS with stunning graphics in C? It's simply out of my mind. And what is time duration it takes for a very basic OS to be created? unlike Windows 7 :p

  • Which programming language is easiest to get a junior position in?

    - by markle976
    I do not have a CS degree but I have lots of intermediate experience with many languages (PHP, C#, Objective-C, Java, VBScript, Actionscript, Javascript, Ruby, etc), mostly freelance or pastime. I have a little experience with Linux (Ubuntu), and a decent bit with Windows. When I look at different languages I find that am interested in most (except maybe VB), but I am not sure what to focus on. So what would be the easiest language to get a job in? Java? PHP? Or would it be easier to get a job as a Junior DBA if I learned Oracle or SQL Server in my spare time?

  • Most effective server side programming language for web development?

    - by ihaveitnow
    This is more a question of pros/cons between PHP and JAVA. Iv been doing research, and iv narrowed it down to those two. And in consideration, id like to go into mobile app dev...So thats +1 for Java. Time taken to learn the language is not an issue...Just would like to know which is the most profitable at the end of all the training. And on a slight note. Can Javascript work with Java? And what is the real advantage of that?

  • What is the weirdest language you have ever programmed in?

    - by sfoulk526
    For me, it was Forth, way back at the end of the eighties! Yes, almost prehistory. But I was an un-degree-ed programmer, unable to afford college, self-taught C and Assembly, and not enough experience to open doors. I was invited to work in software engineering, my dream job by the engineering manager of my company, but...I had to do it in Forth, and the company was willing to teach me. The position was my start into embedded systems programming, and man did I learn a lot! Like, just how easy C and Assembly language REALLY could be! But it was a good journey, and though I never coded again in Forth, my fear of not being able to learn C and Assembly proficiently disappeared... ;-)

  • Is there a good collection library for C-language?

    - by matti
    We have to maintain and even develop C-code of our legacy system. Is there good collection library that would support Java/C# (new versions) style collections. Hashtable, HashSet, etc. Of course without objects, but with structs. The HashTable key limitations to "strings" and ints is not a problem. It wouldn't be bad if it's free even for commercial use. I'm back to C from C# and I must say i'm depressed using our own libraries and the language in general. We're using VS2005 and MS C-compiler if that has nothing to do with anything. Thanks & BR -Matti

  • I need help understanding what Exercise 5-12 is asking for in the C Programming Language book.

    - by marsol0x
    K&R C Programming Language: pg. 105 Extend entab and detab to accept the shorthand entab -m +n to mean tab stops every n columns, starting at column m. entab replaces a number of spaces with a tab character and detab does the opposite. The question I have concerns the tab stops and entab. I figure that for detab it's pretty easy to determine the number of spaces needed to reach the next tab stop, so no worries there. With entab, replacing spaces with tabs is slightly more difficult since I cannot for sure know how large the tab character goes to its own tab stop (unless there is a way to know for sure). Am I even thinking about this thing properly?

  • Assorted list of what's new in Delphi [Language, RTL, VCL]?

    - by utku_karatas
    Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

  • What language is better suited for P2P video streaming?

    - by Roman
    I would like to write a Skype like software which allows P2P video/audio streaming. What language is better suited for that? There are several requirements: Software should be easy to install. It should be easy to program. I want to have access to video information. For example to make a face expression recognition on the fly. It should be free. I am thinking of Python and Java. Which one would be better? Or may be there is a third choice which is better? ADDED Flash is an attractive option since users can use their browser in which flash is installed by default and if not, it's easy to install flash. But I do not know if I can have access to video (if I want to do some processing). Moreover, Flash is not free.

  • How to change language/region in a YQL search.spelling/search.suggestion query?

    Hello, I'm trying to use YQL's spelling and search suggestions, but as much as I try I cant find a way to change the language/region for the query, how is this done? I want to look for spelling/suggestions in spanish/mexico ("es-MX") I'm pretty happy with the results I get for queries in English, but when looking in Spanish I get no results: select * from search.suggest where query="dolor de cabeza" <?xml version="1.0" encoding="UTF-8"?> <query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:count="0" yahoo:created="2010-11-22T17:41:13Z" yahoo:lang="en-US"> <results/> </query> I've looked around for a way to change yahoo:lang="en-US" to yahoo:lang="es-MX" but I cant find andy documentation about it. Thanks!
