  • C struct memory layout?

    - by Eonil
    I have C# background. Very newbie to low level language like C. In C#, memory layout by compiler by default, and I have to specify some special attribute to override this behavior for exact layout. As I know, C does not re-align by default. But I heard there's a little re-aligning behavior which very hard to find. Can I know about C's memory layout behavior? (what should be re-aligned and not)

  • I would like to pipe output of find into input list of scp, how?

    - by user13184
    I'm a novice linux user and I am trying to send a long list of files from one computer to another. The argument list is too long, so I am using find. I am having trouble setting up the expression, though. Can someone help? Here is what I would normally type for a short argument list. scp ./* phogan@computer/directory... Here's I think this might translate into with find. scp find . -name "*" phogan@computer/directory... Maybe I could use piping? Any suggestions would help. Thanks in advance.

  • Manipulate data in the DB query or in the code

    - by DrDro
    How do you decide on which side you perform your data manipulation when you can either do it in the code or in the query ? When you need to display a date in a specific format for example. Do you retrieve the desired format directly in the sql query or you retrieve the date then format it through the code ? What helps you to decide : performance, best practice, preference in SQL vs the code language, complexity of the task... ?

  • Eclipse javascript character encoding

    - by Bardock
    Hi, I'd like to display some language specific characters from javascript but I can't. My app is a Java webapp and the front end is jQuery. All the characters that are sended from the server - in a JSP or with AJAX - are displayed properly. When I want to display some text hardcoded in to the javascript file it's broken. I'm using Eclipse. In the JSP's header I use: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> I've tried this (charset in the script element) too: <script type="text/javascript" charset="utf-8"><c:import url="/JS/mainJS.js" /></script> In my Eclipse I've set the project properties / text file encoding to UTF-8 AND I've checked the JS files' resource properties / text file encoding that is UTF-8 too. But when I try this: $.test = function(){ var s = "éééáááuuuu"; alert(s); } I get: éééáááűűűű The strange thing is that: When I try in a separate html file (in the same project), It's working: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type="text/css"> body {background: #c0c0c0;} </style> <script type="text/javascript"> $(document).ready(function(){ var s = "éááuuúúú"; $("#console").text(s); alert(s); }) </script> </head> <body> <div id="console"></div> </body> </html> Even if I DO NOT use any content type and page encoding settings. What is the problem? What shall I do? (I'm using Apache Tomcat integrated in Eclipse) Thanks in advance!

  • Accessing Erlang business layer via REST

    - by Polyn
    For a college project i'm thinking of implementing the business layer in Erlang and then accessing it via multiple front-ends using REST. I would like to avail of OTP features like distributed applications, etc. My question is how do I expose gen_server calls/casts to other applications? Obviously I could make RPC calls via language specific "bridges" like OTP.net or JInterface, but I want a consistent way to access it like REST.

  • Multiple returns: Which one sets the final return value?

    - by DR
    Given this code: String test() { try { return "1"; } finally { return "2"; } } Do the language specifications define the return value of a call to test()? In other words: Is it always the same in every JVM? In the Sun JVM the return value is 2, but I want to be sure, that this is not VM-dependant.

    - by SepiDev
    I need to know how to start writing an application based on plug-in architecture. I mean how to write a base code an let others develop the application by adding the plug-ins they write. I know that there is some problems in doing such in c++. most people use another language such as python to add plug-ins to their c++ application.

  • How can I create an automatic svn tagging script?

    - by Eran Betzalel
    I want to create a simple script that tags the latest revision to the tags folder, for example: for Trunk directory head revision 114, it will create a tag of this directory to the Tags directory which goes by the name "r114". I don't really care of what scripting language it'll use (as long as it runs on windows). I tried creating such script using SVN CLI tool, but it failed connecting to a SSL repository. How can I achieve that?

  • Faster code with another compiler

    - by Andrei
    I'm using the standard gcc compiler in math software development with C-language. I don't know that much about compilers or compiler options, and I was just wondering, is it possible to make faster executables using another compiler or choosing better options? The default Makefile sets options -ffast-math and -O3 and I think both of them have some impact in the overall calculation time. My software is using memory quite extensively, so I imagine some options related to memory management might do the trick? Any ideas?

  • If I Design a CPU Can I Get it Realized in Hardware at a Reasonable Cost?

    - by mudge
    I want to design a CPU and possibly memory and other hardware. I could do this with a hardware description language. Once I do this is it possible for me to send my designs to a manufacturer who will realize the design in hardware and send back to me the CPU(s) ? Can it be done at a reasonable cost? I want to design and make my own computer system and actually have it realized in hardware.

  • Multiple Inheritance Debates II: according to Stroutroup

    - by asksuperuser
    I know very well about the traditional arguments about why Interface Inheritance is prefered to multiple inheritance, there has been already a post here : http://stackoverflow.com/questions/191691/should-c-include-multiple-inheritance But according to Stroutroup the real reason why Microsoft and Sun decided to get rid off multiple inheritance is that they have vested interest to do so: instead of putting features in the languages, they put in frameworks so that people then become tied to their platform instead of people having the same capability at a language standard level. What do you think ?

  • Powerbuilder resources

    - by afilatun
    I'm recently working in a company where we use PowerBuilder extensively. The only documentation or resources we have access to is some basic course saying things like "Do A, then B and you'll get C". I was wondering if there is some better crash courses or tutorials for this language on the net or somewhere else which actually explain something instead of simply taking me by the hand.

    - by seed
