I can do something like this in Haskell: #!/usr/bin/runghc main=putStrLn "Hello World" Then I can run it with ./hello.hs My question is, why is the first line ignored? Comments in haskell start with -- but the first line still seems to be ignored. It even loads in ghci. The trick also works with Python and Perl. But when I do someth...
I'm a BIG blog reader. I can't stop reading blogs. Blogs helped me find this site (in particular Jeff's blog). However I've come to realize that all the blogs I read deal with one language. Coding Horror Fabulous Adventures In Coding Jon Skeet's Blog Scott Hanselman's Blog Did you guess the language? Well now I'm learning C and usi...

What would be an elegant way of comparing 2 symbolic links in Unix? Assume I have entered the following commands: ln -s /usr/share/g s1 ln -s /usr/share/g s2 ln -s ../share/g /usr/lib/s3 ln -s /usr/share/h s4 then I would like to have a command that says that s1 and s2 are equal (whether /usr/share/g actually exists is not relevant),...

I'm considering using memcached (at some point) in my application i'm currently developing. Eventually, i'm planning on hosting this on Amazon EC2 - i was just wondering, would it be possible to have a linux server (aws instance) running memcached, and use the windows server (aws instance) for the app, but set it to use the linux serve...
Does anyone have a link or document on how to write a screensaver for Linux? ...
I want to run a full-screen application as a screen saver. Is it possible in Linux? It seems that XScreenSaver is not capable of doing this and GnomeScreenSaver has this in their wish list. ...
Hi all, I was going through the details of the linux boot process. It was understood that the primary boot loader resides in 512 byte image (program code + partition table). The 510 bytes comprise of executable code, error messages and partition table information. And the last 2 bytes contain a magic number 0xAA55. It was mentioned that...
I noticed that a little test program which calls nanosleep is showing a huge difference in CPU usage when run on Linux machines with a kernel newer than 2.6.22. #include <time.h> int main (void) { struct timespec sleepTime; struct timespec returnTime; sleepTime.tv_sec = 0; sleepTime.tv_nsec = 1000; while (1) { ...
This is my attempt to cut through extraneous issues raised "Why don’t my system calls work in the Perl program I wrap with pp?" I have created a simple Perl script on a linux system: new-net:~/scripts # cat ls_test.pl @ls_out = `ls -l`; map { print "$_\n" } @ls_out; $out = `sh out_test.sh`; print "$out\n"; This script calls a simp...
I'm looking for a way to get hold of network stats in C on Linux and MacOSX. Specifically, I need to monitor the number of bytes uploaded and downloaded from each network adapter on the system - I don't need to do packet inspection, or differentiate between protocols, just a 'total bytes' counter which I can poll at intervals would be fi...

Hi, Is is possible to prevent Wget from making an output file when there is an error like 404.

I'm pretty curious about how Windows and Linux does memory management with C++ programs. The reason of this curiosity is because I've just made 3 very simple programs in C++ portable between Linux and Windows. The code was exactly the same. The hardware too. But the results were incredibly different! Both tests were repeated 10 times an...
What is the best operating system to develop while using C++? I would like the OS that has more tools and software for C++ development. I also want to develop only for the command line, because I find GUI development in C++ to be confusing. ...

I'm looking for some real information about the effect of systemtap on performance. I know that static kernel probes are documented somewhere on their website (with stats), but what about userspace probes? I saw this post on their mailing list (http://sourceware.org/ml/systemtap/2009-q1/msg00518.html) which points at a possibility of si...
