I'm planning to sync 2 folders from 2 dyfferent servers using a cronjob scheduled to run every hour. The script that is to be scheduled will check if a previous instance is already running, and if not, continue with processing. so, the first stage is to sync these folders. Daily (or more often), the second server will have 1-2 thousands...
I'm interested in the differences in work flow, code management, tools you might be expected to be familiar with etc. Not stuff like "your code will need more rigorous testing", or "your code will need to be more readable/maintainable" or "getting paid"! These are obvious I think. Also, I don't really want a list of the pros and cons ...
What is meant by CPU Utilization of a process? How to measure it? What are the means for reducing it? I have always been confused with this concept. I have tried to measure the CPU used by using 'top' command in the Linux. But, what I notice is, when there are no other user process running, then my process seem to spike up and take ...
Possible Duplicate: Maximum number of threads in a .NET app? Is there a limit on the number of threads we can create in a .NET application ?

We have a batch process consisting of about 5 calculations that happens on each row of data (20 million rows total). Our production server will have around 24 processors with decent CPUs. Performance is critical for us. Assuming that our algorithms are pretty efficient, what would be the best way to achieve maximum time performance fo...

Hi everyone, Some programs return immediately when launched from the command line, Firefox for example. Most utilities (and all the programs I've written) are tied to the shell that created them. If you control-c the command line, the program's dead. What do you have to add to a program or a shell script to get the return-immediately b...
I'm having a problem on a master MySQL (5.0, Linux) server: I tried to add a comment to a table row, which translates into an ALTER TABLE command. Now the process is stuck on 'copy to tmp table', copying the 100'000'000+ rows. Disk IO usage is uncomfortably high. Since the master is using replication, I'm unsure if I can kill this proce...
I am having a hell of a time trying to write a "kill all other daemon processes" function for use within a bash daemon. I do not ever want more than one daemon running at once. Any suggestions? This is what I have: #!/bin/bash doService(){ while do something sleep 15 done } kil...
In pseudocode, here's what I'm doing: Process proc = runtime.exec(command); processOutputStreamInThread(proc.getInputStream()); processOutputStreamInThread(proc.getErrorStream()); proc.waitFor() However, sometimes processOutputStreamInThread doesn't see any output and sometimes it does. Roughly, the method creates a BufferedInputStre...

I'm creating a python script to sort a lot of images (game screenshots). I found a way to do that in imagemagick : I know that, if a specific square of the image is the same as the reference crop, then the image is of category one. If not, I check for another crop and another category, and if that doesn't fit either, I put the image in ...
