Here's a piece from me on how to do a search and replace across many files in one line of perl, for several kinds of cases.
If you're bored with blogging and ready for new worlds to conquer, podcasting might be just the impetus you need to refuel your interest in Internet publishing. The term is something of a misnomer. You don't need an iPod to create or receive a podcast, and it's not really a broadcast.
Say you have access to multiple links to the Internet, such as several wireless networks in range. Wouldn't it be nice to combine all that bandwidth into one big fat pipe for your downloading pleasure? Unfortunately it's not so easy.
Don't you hate it when the word completion feature wants to finish your words for you? Or do you love it? Learn how to customize (or kill) Autocorrect in OOo and live in word-processing peace.

Are you still not doing backups on a regular basis--or at all? With this easy-to-follow procedure and ready-made scripts, you're out of excuses.
It's a dangerous Internet out there, kids. If you are going to work on remotely connected machines, do it safely. If you need to work with files on a remote server you might find just what you're looking for in sshfs -- a tool for mounting a remote filesystem transparently and securely as if it were just another directory on your local machine.
Mirdir provides a quick and easy way to make an ad hoc backup of important data. With it you can copy a file or directories to your keydisk, or save redundant copies of data you can't afford to lose. It tries to do only one thing, and do it well: mirror a directory.
These instructions are for HFS+ formatted iPods, and these instructions work on Mac and Linux. All Mac iPods are HFS+. After the Linux installation you will be able to install Doom (iDoom) on your nano. You can also watch full-color movies with the new movie support in iPod Linux!
Utility programs like cp have new features you may not have seen. Here’s the third in a series about some of the handiest.
Just in the last week, 3 proprietary software companies informally discussed with me on how to open source their products. I suggested the following migration approach and thought would share the same for wider community consumption.
Years ago, there was a saying that Unix beginners use grep because it's all they know about, intermediate users use fgrep because it's supposed to be faster, and advanced users use egrep because they've tested it.

"Klipper is the KDE clipboard utility. It stores clipboard history, and allows you to link clipboard contents to application actions. That's the common explanation you get from most people and online manuals when seeking information about Klipper. But what else can Klipper do? Is that ALL it does? Can we empower it to be what cut and past is in Windows? (ducks the possible flames) Perhaps. Grab a pen and paper Klip...let's see what this thing can do. Please note that this article is written with the assumption that you are using KDE 3.4 or higher.
Linux's record for reliability may be the polar opposite of what critics consider the crash-a-day life of Windows. Yet, the fact that Linux crashes are rare means that an unexpected outage throws many in unmapped territory. Learning the proper steps to prevent such crashes can help Linux admins avoid many headaches over the long term.
Linksys WRT54GS + OpenWRT + ChillSpot + FreeRadius (with Mysql authentication and accounting ) + PHP/Perl = Wireless HotSpot

Wireless cards can be quite a bit of trouble for Linux users. Very few manufacturers have any interest in writing Linux drivers or releasing information about their cards so other people can use this information to write Linux drivers.
If you use charts to represent relationships between data or objects in presentations or project reports, try Graphviz. Graphviz is visualization software is designed to help you easily create structural information.
