Hi I'm working currently on a small microhpone, connected to PC via an FPGA. The FPGA spits a raw datastream via UART/USB into my computer. I'm able to record, play and analyze the data. But I can't play the "live" audiostream directly. What works is saving the datastream in PCM raw-format with a custom made C-program, and piping the ...
I'd like to find out how current google's cached copy of a large set of pages is. I think I need to look in the logs for IP's, check to find user-agent "googlebot", then export a list that says each page and when it was last visited. I imagine this could be a cron job that runs weekly. If this is right, how would I write the s...

This script runs for 2 hours on our unix server. Any ideas how to speed it up? Notes that the \s stands for a space and \t stands for a tab, ...

People these days create their ZIP archives with WinZIP, which allows for internationalized (i.e. non-latin: cyrillic, greek, chinese, you name it) file names. Sadly, trying to unpack such file causes trouble: UNIX unzip creates garbage-named files and dirs like "®£¤ ©¤¥èì". Java and its jar command fails miserably on such archives. I...

I've setup a simple TCP file transfer. Everything appears to work OK, except for the received file size is sporadically a smaller size than the file that was sent. There doesn't appear to be any pattern to the size of the received file. (in the code below, note that the typical client/server rolls are reversed) My client code is like...
We recently had a problem with our test LDAP server - it was hung and wouldn't respond to requests. As a result, our application hung forever* while trying to bind to it. This only happened on Unix machines - on Windows, the ldap_simple_bind_s call timed out after about 30 seconds. * I don't know if it really was forever, but it was at ...

NOTE: This is not the same question as Python: Persistent shell variables in subprocess, as that question is actually about environment variables, not shell variables. I'm trying to automate a basic benchmark that I'm doing in csh using the shell built-in time command. You can tweak the output of time by setting the variable of the sam...

In a UNIX-y way, I'm trying to start a process, background it, and tie the lifetime of that process to my shell. What I'm talking about isn't simply backgrounding the process, I want the process to be sent SIGTERM, or for it to have an open file descriptor that is closed, or something when the shell exits, so that the user of the shell ...
