Challenges. Challenges and more Challenges...

Updated 11-14-2011 at 11:35 AM by m3rl1n (Found some interesting answers.)

In my last blog I mentioned being proud of having closed that platinum plated Microsoft door (maintenance and updates became too much of an investment - with no impressive return), and I promissed myself to regulary update this blog - oops!

I have been cramming C++, MySQL, and recently I developed my first X-Window application using QT4. Now that I got a fair idea about the basics, it is time to jump into deep waters, and start programming like I used to in VB. I think that is the...

Merging two log files

Posted 11-14-2011 at 05:52 AM by zhjim

Today I needed to merge two log files in cronological together. Heres my way about.

copy the two files to one host. (scp file name@server:~userhome
get the hostname infront of each line. (sed -i s/^/hostname/g first_file; ...)
cat ./first_file ./second_file | sort -k 3 > ./new_log

-k in sort stands for key. In my turn the datetime was the third field.

Improvements:
Get some color into the diffrence hostsnames.

Kind of neat.

Beginning to like gpxe more and more. So far we have it for setting up to install linux distros via the net. Now we have it to load clonezilla. There were no instructions for setting it up with clonezilla except for pxe usage. That information was enough to make adjustments to get clonezilla to load and run via gpxe. No more messing around with tftp except when needed.

Tried to upgrade the proms to gpxe on some 3com cards, but no luck. they might be locked. Have some 3com cards...

High CPU usage + underclock vs. low CPU + normal/high clock

Posted 11-13-2011 at 03:02 PM by the dsc (linux-related notes)

This is just a question rather than a typical blog post. I know blogs aren't really supposed to be used for that, but I think it's justifiable since it's not that important or urgent, even though it has some practical applications. So I'm not "stealing" attention from other users with more pressing matters over there.

The question is basically "what gets more work done":

a) higher CPU usage per process (limiting less or not limiting the usage at...

Made the move to Linux - a kind of personal intro

Posted 11-13-2011 at 01:15 AM by forbinproject

About a month ago, I tried Linux for the first time on this system with a dual-boot between Vista and Ubuntu (Vista came with the computer). After about a month of working with a dual-boot system, for whatever reason, the Vista partition was not as stable as it could have been; that is, there was some sort of new winsock error that forced a very long boot to happen. I was in the midst of backing up files, so it took me a little longer to make the full switch. The re-install I had made of Vista...
