How do you run Scheme programs from the terminal in linux(ubuntu)? Also how to accept arguments from the command-line in a Scheme program?
Edit: Im using the DrScheme implementation.
Let's imagine a situation: I have two Python programs. The first one will write some data (str) to computer memory, and then exit. I will then start the second program which will read the in-memory data saved by the first program.
Is this possible?
What exactly does an operating system do? I know that operating systems can be programmed, in, for example, C++, but I previously believed that C++ programs must be run under an operating system? Can somebody please explain and give links? thanks in advance, ell
I have heard that in Haskell, creating a multi-threaded application is as easy as taking a standard Haskell application and compiling it with the -threaded flag. Other cases, however, have described the use of a par command within the actual source code.
What is the state of Haskell multi-threading? How easy is it to introduce into programs? Is there a good multi-threading tutorial that goes over these different commands and their uses?
I have some customers who want to use our speech therapy software in Hebrew.
The programs are in VB6. The best option I'm aware of are:
use the Forms 2.0 controls from MS Office, but you can't distribute them.

Any other options?
I'm looking for a virtual webcam driver to use in a .NET project, this project will be GPL, and have no idea how many installations there will be
The idea is that the application is using the webcam without locking the device.
Found a couple of programs that do the job, but either in application and/or too expensive:
* http://www.softservice.org/products_camsplitter.html (9.99$/installation)
* splitcamera.com (program, no SDK available)
All idea's are welcome

I got this great idea that I'm thinking about implementing, but before I go into the deep end I wanted to get a clue about what options I have.
I'm looking for an open source, programmable video player.
Must:
Play video files from a user's computer not a server
Connect to a server to retrieve/send info (not limited to file xfer)
Prefer:
Web-based player
Easily programmable (because i'm no pro at programming <;
Any names of open-source programs or players that you guys think I could use?
Any help is really appreciated
I'm relearning UNIX commands to use git on windows using MINGW32.
When I launch a program, for example "$ notepad hello.txt" I can't use the shell again until I close the notepad file or CTRL-C in the shell.
How do I essentially fork a new process so I can use both programs?
My game has delta time for frame independent movement, at 250 fps run perfectly smooth, but if i limit the fps to 60, the game slow down for a 2-4 seg every 20 seg aprox, even in small programs i have this same problem.
no memory is created or released
i comment everything i can and the problem persist
thanks and sorry for my english
This is kind of a philosophical question.
Basically people often ask if I am logging - and since I am not a full time programmer, but someone who programs often but is actually more of a requirements analyst, I don't know all the best practices.
I use Java a lot so I often do things like
System.out.println()
What's the difference in theory between the two? Ultimately aren't I also logging? Esp, if I prefix my comments with something like "ERROR:" or "WARN:" ?
Is there any mobile platform that allows me to run Java Applets? In absence of browser integration, at least Java SE capabilities. I've heard of a mobile device capable of running Windows XP - that would probably include support for Java SE and applets; does any one have any hands-on experience with such a device? How well does it perform in terms of Java programs execution?
I'd like to make a simple x86 assembler. I'm wondering if there's any tutorials for making your own assembler. Or if there's a simple assembler that I could study.
Also, I wonder what tools are used in looking at and handling the binary/hex of programs.
I am using a ServerSocket port to run one instance only of my Java Swing application, so if a user tries to open another instance of the program, i show him a warning that "Another instance is already open". This works fine, but instead of showing this message i want to set focus on the running application itself, like some programs does (MSN Messenger), even if it was minimized.
Is there a solution for this for various operating systems ?
Hello,

I'm searching for the source code of a compiler capable of creating Win32 programs from an input program in a programming language (It doesn't matter which, maybe the simpler the better)
Yet I can't find anything right for me and huge compilers like GCC make me extremely confused as they have so many features that I don't know where to start.
Is there an OpenSource Win32 micro-compiler for some programming language out there I could take a look at?
This isn't really a programming question but... Is there any way to draw online a lattice for a material, like a compound? i.e. a 3D gridlike pattern? I know there are some applications for drawing mathematical lattices, but the notation to me is unfamiliar - are there simply programs or applets or something for drawing lattices like in a compound?
Any applications, tools, or just add-ins to existing programs that work well for managing the part labeling between figures and written specifications, say similar to how LaTex works for renumbering diagrams within a specification?
Hello,
I try to get a coredump, so i use :
ulimit -c unlimited
I run my program in background, and I kill it :
kill -SEGV %1
But i just get :
[1]+ Exit 1 ./Test
And no coredumps are created.
I did the same with other programs and it works, so why that didn't work with all ? Anybody can help me ?
Thanks. (GNU/Linux, Debian 2.6.26)
I need to pass an array of integer arrays (basically a 2 d array )to all the processors from root.I am using MPI in C programs. How to declare MPI datatype for 2 d array.and how to send the message (should i use broadcast or scatter)
I have a client and server program (both in Obj-C) and I am transferring files between two devices using the programs.
The transferring is working fine, but I would like to display to the user what transfer rate they are getting.
So I know the total size of the file, and how much of the file has been transferred, is there a way to figure out the transfer rate from this information, and if not, what information do I need to calculate the transfer rate?
Thanks
Hello
For an embedded system with internet (which works under a set-top box) I want to develop a primitive Facebook interface where users can type their user-names and password, showing their latest notificationsa, messages and other casual stuff via the recent Facebook Graph API.
This middleware program uses Java ME to run programs (such as this simple facebook app) and it can connect to internet however it doesn't have a real web browser.
Under this circumstance, is it possible to achieve such Facebook application? If you think so, what approach would you suggest ?
Thanks
Hi,
I'm writing an embedded ftp server, and I cannot get the listing format correctly. The server works completely, only programs like FileZilla cannot interpret the listing format. Here's a sample listing:
-rwxr--r-- 1 owner group 640 1970 01 01 test
-rwxr--r-- 1 owner group 13440 1970 01 01 test.html
-rwxr--r-- 1 owner group 512 1970 01 01 test2.txt
Which is basically:
permissions[tab]number?[tab]owner[tab]group[tab]filesize[tab]date[tab]filename
What am I doing wrong?
Thanks,
Yvan
