• [Linux] Coding a GTK+ application without window manager?

  - by ShoX

  Hi, I want to code sth. that basically works like TiVo. Switch it on, you only see the menu or an output, so no underlying OS or anything else is directly visible to the user. So I want to use Linux as base. Can you suggest a good base distribution? Can I code a frontend without having a window-manager up and running? If yes, is that possible with java-gnome or what language/gui-framework combination would you suggest? If no, what's the minimal window manager that can handle fancy menus, etc? What does it take to create video-overlays over a HD-stream? Are there some libraries I should take a look at? Thanks

• JQuery SimpleModal

  - by Matt

  I've got a submit button inside my modal, and when it's pressed nothing happens! How do I make my form submit when the push my submit button? I don't want to use $('form').submit(); because then php doesn't detect that my button was clicked. <script type="text/javascript" language="javascript"> $(document).ready(function () { $('#btnAdd').click(function (e) { //clicking the button shows the modal popup up e.preventDefault(); $('#AddCareerItem').modal(); }); $('#btnCancelCareerContent').click(function (e) { //close the modal with the cancel button $.modal.close(); }); }); </script>

• is PHP itself transforming into a framework or big library?

  - by Elzo Valugi

  At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

• General question: Filesystem or database?

  - by poeschlorn

  Hey guys, i want to create a small document management system. there are several users who store their files. each file which is uploaded contains an info which user uploaded it and the document content itself. In a view there are displayed all files of ONE specific user, ordered by date. What would be better: 1) giving the documents a name or metadata(XML) which contain the date and user (and iterate through them to get the metadata) or 2) giving the files a random/unique name and store metadata in a DB? something like this: date | user | filename What would you say and why? The used programming language is java and the DB is MySQL.

• How bad is for SEO to "redirect" an user depending on his browser locale ?

  - by bgy

  For a personnal page I use the MultiViews options in Apache to determine which page he should see depending on his locale. Here is what I do. Options MultiViews AddLanguage fr .fr AddLanguage en .en <IfModule mod_negotiation.c> LanguagePriority fr en </IfModule> I am wondering if it is bad for SEO to do this since Googlebot will probably fall on 'fr' or 'en' but not both. Would it be fixed if I add a link inside my page to the different language page.

• How do I convert an arbitrary list of strings to a SQL rowset?

  - by Jim Kiley

  I have a simple list of strings, which may be of arbitrary length. I'd like to be able to use this list of strings as I would use a rowset. The app in question is running against SQL Server. To be clearer, if I do SELECT 'foo', 'bar', 'baz' I get 'foo', 'bar', and 'baz' as fields in a single row. I'd like to see each one of them as a separate row. Is there a SQL (or SQLServer-specific) function or technique that I'm missing, or am I going to have to resort to writing a function in an external scripting language?

• Converting digits, generated by weblog service, to Arabic form

  - by Sorush Rabiee

  sorry if this is irrelevance :-) I need to write something in my html code to convert digits of form 0123456789 to ?????????? (Persian digits uni06F0..uni06F9). the number of visitors is generated by blog service. and I want to convert its digits to Arabic. Counter: ????? ????????????? : <BlogSky:Weblog Counter /> ??? the Persian part of above code mean 'Number of visitors' and 'Persons' (from left to right). but digits are represented in latin (0123...). Is it possible to write something like a function in html? i want it to be a global one for using in weblogs. Note: I don't know anything about web programming languages. I'm not sure about language of above code. (html?)

• Pass codeigniter translation array to jQuery Function

  - by grolle

  Hi, I’ve a problem by passing an array to a jQuery function. Some code: // in the language file $lang['daynames'] = array('So','Mo','Di','Mi','Do','Fr','Sa'); //In the view var config = { basePath : '' }; // THIS WORKS GREAT!!! var days = new array('lang-line('daynames')); ?'); //in the js-File $(function() { $("#datepicker").datepicker({ dateFormat : 'dd.mm.yy', showWeek : true, firstDay : 1, weekHeader : 'KW', dayNamesMin : days, monthNames : ['Januar','Februar','März','April', 'Mai','Juni','Juli','August','September', 'Oktober','November','Dezember'], onSelect : function(dateText,inst){ } }); }); If I do lang-line(‘daynames’)); ? in the view everything looks fine, so what is wrong here? Thanks and best regards ...

• Windows API Textfield with offset characters

  - by genesys

  Hi there! Is it possible using the Windows API, to create a textfield that lets me offset characters by exact pixels? if so - how? for example, I would like to place two O letters on top of each other, such that they form something like an 8 ? context is an application for a language where most of the glyphs are written left to right, but sometimes some of the glyphs are stacket on top of each other. Windows API because the framework we're using already uses the Windows API for the whole GUI. Thanks!

• Does Ruby/Rails require more unit testing than say a PHP app?

  - by Blankman

  I don't find the unit testing push in the PHP market like I see/read in the ruby/rails arena. Could one just as easily NOT unit test in ruby/rails as in php, or is ruby just too bendable and breakable that it "more" recommended to test in ruby than in php? Meaning there are large code bases like vBulletin, and from what I can tell, they don't unit test. I hope you understand what I am asking here, not the pros/cons of testing, or whether one should test or not, but rather, does one language need to be tested more than another? maybe its easy to write buggy code, or break during refactoring etc.

• Using system time directly to get random numbers

  - by Richard Mar.

  I had to return a random element from an array so I came up with this placeholder: return codes[(int) (System.currentTimeMillis() % codes.length - 1)]; Now than I think of it, I'm tempted to use it in real code. The Random() seeder uses system time as seed in most languages anyway, so why not use that time directly? As a bonus, I'm free from the worry of non-random lower bits of many RNGs. It this hack coming back to bite me? (The language is Java if that's relevant.)

• SQL query to select distinct record with 2 or more repetition in another field

  - by kyohiros

  So I have this table of book orders, it contains 2 columns, one is the order ID(primary key) and another is the ID of the book that the customer ordered. For example: | OrderID | BookID | | 0001 | B002 | | 0002 | B005 | | 0003 | B002 | | 0004 | B003 | | 0005 | B005 | | 0006 | B002 | | 0007 | B002 | What I want is to get the IDs of the books that got 2 or more purchases/orders, for example if I run the SQL query against the above data, I would get this as the result: | BookID | | B002 | | B005 | I don't know if this can be archived in SQL or I have to built a simpler statement and repetitive run the query against all the records in another language. I need some help and thanks for reading my question.

• failed to load resource

  - by Jason94

  Im trying to set up a simple mp3 player: <script language="javascript"> $(document).ready(function() { $('a.media').media( { width: 300, height: 20 } ); }); </script> and then <a class="media" href="piano.mp3">piano</a> But i get the following error: Failed to load resource I have followed the tutorial at http://jquery.malsup.com/media/audio.html, and if i click to view source and clikc on piano.mp3 chrome opens up its built in media player and plays the song, so the link and location is correct... Anyone got a clue?

• SVN merge adding parameters. WTF? Or how to do big merges?

  - by HeavyWave

  I am doing an SVN merge for a branch, and in one of the files I see this: GetQueryReferenceData(int sessionId, Int32 sessionId) Which means that the merge tool just added another parameter without asking any questions. Imagine if it was a call to Substring(0) and in another branch it would be Substring(0,2). That is completely different behavior, how does it even get to decide which one to choose? Good thing it came up during compile time. The problem is that it will not be marked as a conflict and will be merged automatically. That is very dangerous behavior and if you don't have the luxury of having a unit test for every line of code - you are screwed. What am I doing wrong and how to do big merges without the merging tool putting in dangerous changes silently? Is there a merge tool that is not language agnostic? I am using Tortoise SVN.

• Delphi developer switching to C#

  - by Dorin Duminica

  Hello, I'm a Delphiholic for quite some time now and lately I was thinking of learning some C# as well, however I'm kinda' "afraid of the unknown", I've done some simple apps as a test drive for C# and I have to admit that I've liked it, HOWEVER I do not really like the IDE... that being said here's the question that I would appreciate if others who went down this path would answer: As a Delphi developer what are the "main basic" changes from the Delphi language(by basic I mean basic -- utility functions, streams, etc.), I'm used to add "System, Classes, Windows" to uses not "use System.XXX.YYY.ZZZ", I'm trying to make a partial equality in my mind from Delphi to C# until I can see where does Delphi go hand-in-hand with C# and so on... I hope the question is pretty clear, if not, do not hesitate to swear me and I'll try to clarify as well as I can :-)

• What should I know about Python to identify comments in different source files?

  - by Can't Tell

  I have a need to identify comments in different kinds of source files in a given directory. ( For example java,XML, JavaScript, bash). I have decided to do this using Python (as an attempt to learn Python). The questions I have are 1) What should I know about python to get this done? ( I have an idea that Regular Expressions will be useful but are there alternatives/other modules that will be useful? Libraries that I can use to get this done?) 2) Is Python a good choice for such a task? Will some other language make this easier to accomplish?

• OS monitoring using JAVA

  - by Puneri

  I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

• Should I learn Haskell or F# if I already know OCaml?

  - by Unknown

  I am wondering if I should continue to learn OCaml or switch to F# or Haskell. Here are the criteria I am most interested in: Longevity Which language will last longer? I don't want to learn something that might be abandoned in a couple years by users and developers. Will Inria, Microsoft, University of Glasgow continue to support their respective compilers for the long run? Practicality Articles like this make me afraid to use Haskell. A hash table is the best structure for fast retrieval. Haskell proponents in there suggest using Data.Map which is a binary tree. I don't like being tied to a bulky .NET framework unless the benefits are large. I want to be able to develop more than just parsers and math programs. Well Designed I like my languages to be consistent. Please support your opinion with logical arguments and citations from articles. Thank you.

• Porting library from Java to Python

  - by Mike Griffith

  I'm about to port a smallish library from Java to Python and wanted some advice (smallish ~ a few thousand lines of code). I've studied the Java code a little, and noticed some design patterns that are common in both languages. However, there were definitely some Java-only idioms (singletons, etc) present that are generally not-well-received in Python-world. I know at least one tool (j2py) exists that will turn a .java file into a .py file by walking the AST. Some initial experimentation yielded less than favorable results. Should I even be considering using an automated tool to generate some code, or are the languages different enough that any tool would create enough re-work to have justified writing from scratch? If tools aren't the devil, are there any besides j2py that can at least handle same-project import management? I don't expect any tool to match 3rd party libraries from one language to a substitute in another.

• Creating an Application to Save Arbitrary Application State

  - by ashes999

  See this SuperUser question. To summarize, VM software lets you save state of arbitrary applications (by saving the whole VM image). Would it be possible to write some software for Windows that allows you to save and reload arbitrary application state? If so (and presumably so), what would it entail? I would be looking to implement this, if possible, in a high-level language like C#. I presume if I used something else, I would need to dump memory registers (or maybe dump the entire application memory block) to a file somewhere and load it back somewhere to refresh state. So how do I build this thing?

• Why are C, C++, and LISP so prevalent in embedded devices and robots?

  - by David

  It seems that the software language skills most sought for embedded devices and robots are C, C++, and LISP. Why haven't more recent languages made inroads into these applications? For example, Erlang would seem particularly well-suited to robotic applications, since it makes concurrent programming easier and allows hot swapping of code. Python would seem to be useful, if for no other reason than its support of multiple programming paradigms. I'm even surprised that Java hasn't made a foray into general robotic programming. I'm sure one argument would be, "Some newer languages are interpreted, not compiled" - implying that compiled languages are quicker and use fewer computational resources. Is this still the case, in a time when we can put a Java Virtual Machine on a cell phone or a SunSpot? (and isn't LISP interpreted anyway?)

• Graphic editor opensource project example on c++ underlying composite pattern

  - by G-71

  Can you tell me when I can see a some opensource project (only project on C++ language), which is simple graphic editor, ?ontaining following primitive (for example): an ellipse, a rectangle, a line. And desirable, that to be able to group this primitive in one primitive (for example, Word Grouping - Group). Composite pattern use is desirable in this project. I want to see how to organize classes, but more serious for me is to see how organize grouping operation. I searched for it on codeproject.com codeproject.com, codeplex.com, but not found this. I have already some source http://pastebin.com/xe4JF5PW But in my opinion, this code is dirty and ugly. Therefore, I want to see some opensource project for example. Thanks!

• fast on-demand c++ compilation [closed]

  - by Amit Prakash

  I'm looking at the possibility of building a system where when a query hits the server, we turn the query into c++ code, compile it as shared object and the run the code. The time for compilation itself needs to be small for it to be worthwhile. My code can generate the corresponding c++ code but if I have to write it out on disk and then invoke gcc to get a .so file and then run it, it does not seem to be worth it. Are there ways in which I can get a small snippet of code to compile and be ready as a share object fast (can have a significant start up time before the queries arrive). If such a tool has a permissive license thats a further plus. Edit: I have a very restrictive query language that the users can use so the security threat is not relevant. My own code translates the query into c++ code. The answer mentioning clang is perfect.
