  • Allowed characters in linux environment variable names

    - by Christian Semrau
    What characters are allowed in linux environment variable names? My cursory search of man pages and the web did only produce information about how to work with variables, but not which names are allowed. I have a Java program that requires an defined environment variable containing a dot, like com.example.fancyproperty. With Windows I can set that variable, but I had no luck setting it in linux (tried in SuSE and Ubuntu). Is that variable name even allowed?

  • JavaME: Is it possible to run a MIDLet on a CDC configuration ?

    - by Leonel
    Hi, We have an application running on CLDC 1.1/MIDP 2.1, based on Midlets and lcdui. Is it possible to run the same application on CDC 1.1 with the PBP profile ? If so, where should I even start ? I'm using Sun WTK 3.0. With CLDC, the starting point is a JAD file, which indicates the name of the main midlet class. What is the starting point of an application on CDC ?

  • Why doesn't web browsers have built in validators?

    - by August Karlstrom
    As far as I know there is no web browser with built in validators for HTML, CSS and Javascript. Developing web pages without validation is like using a compiler that doesn't do syntax analysis. Even Firefox with its excellent plugins aimed at developers like Firebug lacks plugins for CSS and Javascript validation. Wouldn't it be useful to have these plugins? Am I missing something?

  • What is the best way to download files via HTTP using .NET?

    - by Shamika
    In one of my application I'm using the WebClient class to download files from a web server. Depending on the web server sometimes the application download millions of documents. It seems to be when there are lot of documents, performance vise the WebClient doesn't scale up well. Also it seems to be the WebClient doesn't immediately close the connection it opened for the WebServer even after it successfully download the particular document. I would like to know what other alternatives I have.

  • Base SDK Missing? No, I fixed that. Still?!

    - by Moshe
    XCode 3.2.3 Beta does not allow building for below 3.2. I opened a project that was made in an earlier XCode. For some reason, the base SDK is reported as missing even after changing it to 4.0. Other projects from earlier XCode do not have this issue. What can I do?

  • Design-time properties in IB?

    - by Krumelur
    Coming from the .NET world into ObjC and iPhone development, I'm used to providing design-time support for my UI classes. For example, say that I have a custom button class with a color property. I want to be able to set this color in design time from IB. How can I accomplish this? Is it even possible? Worth the effort?

  • Which TextEditor is easiest to customize for a new scripting language?

    - by Simone Margaritelli
    It's been more than an year that i'm developing a new scripting language with its own grammar rules and constructs. I'd like to give the users of this language some minimalistic ide to work with, but i don't want/have time to make one from scratch so i'd like to take one already existing (it has to run on Linux platforms natively, so no windows-only editors plz) and customize it. Well, which one is the easiest to customize without changing the source code and recompiling it, maybe even with plugin support? Thank you.

  • mint.com javascript dropdown effect

    - by Adam McMahon
    I need to recreate an effect that mint.com has on another website. When you go to the transactions page and click on one of your transactions a tab pops up underneath that says edit details. When you click on that tab a div will drop down exposing more details about the transaction. I don't even know what this kind of effect this is called but I need to know to recreate something like this preferably with jquery. There are some screenshots of what I'm talking about below.

  • "Correct" Dialog / UI font on Windows

    - by peterchen
    When creating a control (e.g. an edit control) on the fly using CreateWindow, it usually starts out with an ugly (boldish sans serif) font. Usually I wok around that by grabbing the parent dialog's font, and setting it to the control - I can't even say if this is a good idea. How do I "legally" fetch the right font?

  • Is a display list best for this? (OpenGL)

    - by user146780
    I'm rendering 2D polygons with the GLUTesselator the first time, then they are stored in a display list for subsequent use. I think VBO's might be faster, but since I can't access the stuff that the tesselator outputs, and since it uses mixes of gl_triangle, quad, strip etc, i'm not sure how I could do this, even though I would like to use VBO's once the GLUTesselator is done with them for optimal performance. Thanks

  • JavaScript Trigger window.open When a User Clicks Anywhere on Page

    - by Joe Hammonds
    I have a problem that I have been trying to figure out and haven't been able to get past it because Chrome/FireFox/IE do not publicly publish their "rules" for pop up blocking when it comes to JavaScript, Flash, etc. I am trying to trigger a window.open() when a user clicks anywhere on page. I've tried this: document.onclick = window.open("http://msn.com"); But all 3 browsers are blocking the popup, even though it is a user interaction.

  • Why and what for: java enum

    - by Mat Banik
    Today I was browsing through some question on this site and I found mention of enum being used in singleton pattern and that there are some thread safety benefits to such solution. I never used enums and I have been programing in java for more than couple a years now. And apparently they changed a lot and now they even do full blown support of OOP within them selfs. Now why and what for should I used enum in day to day programing?

  • Yet another Memory Leak Issue (memory is still gone when program terminates)- C program on SLES

    - by user1426181
    I run my C program on Suse Linux Enterprise that compresses several thousand large files (between 10MB and 100MB in size), and the program gets slower and slower as the program runs (it's running multi-threaded with 32 threads on a Intel Sandy Bridge board). When the program completes, and it's run again, it's still very slow. When I watch the program running, I see that the memory is being depleted while the program runs, which you would think is just a classic memory leak problem. But, with a normal malloc()/free() mismatch, I would expect all the memory to return when the program terminates. But, most of the memory doesn't get reclaimed when the program completes. The free or top command shows Mem: 63996M total, 63724M used, 272M free when the program is slowed down to a halt, but, after the termination, the free memory only grows back to about 3660M. When the program is rerun, the free memory is quickly used up. The top program only shows that the program, while running, is using at most 4% or so of the memory. I thought that it might be a memory fragmentation problem, but, I built a small test program that simulates all the memory allocation activity in the program (many randomized aspects were built in - size/quantity), and it always returns all the memory upon completion. So, I don't think that's it. Questions: Can there be a malloc()/free() mismatch that will lose memory permanently, i.e. even after the process completes? What other things in a C program (not C++) can cause permanent memory loss, i.e. after the program completes, and even the terminal window closes? Only a reboot brings the memory back. I've read other posts about files not being closed causing problems, but, I don't think I have that problem. Is it valid to be looking at top and free for the memory statistics, i.e. do they accurately describe the memory situation? They do seem to correspond to the slowness of the program. If the program only shows a 4% memory usage, will something like valgrind find this problem?

  • Should I be concerned with infected zip files?

    - by Peter Smith
    I'm writing a ASP.NET application to process user submitted zip files and limiting my extraction of files from it to only the extensions I want. I've heard of infected zip files attached to emails and I was wondering if I should be concerned about extracting data from infected zip files in my application. I don't plan on executing the content inside of the zip file, but will opening and extracting from an infected zip file cause the file to execute a virus even if I'm not executing any content inside of the zip file?

  • Why does Option not extend the Iterable trait directly?

    - by oxbow_lakes
    Option is implicitly convertible to an Iterable - but why does it not just just implement Iterable directly: def iterator = new Iterator[A] { var end = !isDefined def next() = { val n = if (end) throw new NoSuchElementException() else get end = true n } def hasNext = !end } EDIT: In fact it's even weider than that because in 2.8 Option does declare an iterator method: def iterator: Iterator[A] = if (isEmpty) Iterator.empty else Iterator.single(this.get)
