In this week's exciting chapter of Linux.com forum traffic, planning for an IT career with emphasis on Linux, how to go multilingual and multiprocessor, and unanswered questions for programmers and sound gurus.
Linux: Stepping stone to systems administration
User crisnoh posed the IT career question in the Miscellaneous Discussion forum. "I have a vague sort of notion that I'd like to do systems administration, and wouldn't it be great if those systems were running Linux? The options as I see them are pretty broad and overwhelming. I'm just trying to find some information on what skills tend to be in pretty high demand, what sort of degree/certifications/whatever I should be pursuing, pretty much anything."
Khabi -- who has worked as a sysadmin for several years -- responded with some solid advice, including the mix of subjects to study up on (such as managing Internet services, basic programming, and databases), his own experience on the value of certification, and a few tips on finding that first job. "Something else that will help more then you think: Completely switch over to a Linux distro on your home machine. Forcing yourself to use it day in and day out will help a *great* deal. Especially, if there aren't any ports for apps you need in Linux. Finding / troubleshooting / installing apps that could fill the functionality you're used to having will build your skillset."
Multiple processors and GNU utilities
User wwood asked the Programming forum "what the current state is and what the future is for GNU utils like grep, sed, etc. when it comes to multiprocessing."
He clarified in a follow-up for forum regular proopnarine that he wants to take advantage of his system's multiple processors when running heavy scripts, whether by multithreading or parallelism.
Proopnarine responded that it is possible to divide tasks among multiple CPUs in a bash script, but suggested that a more in-depth answer would be found by consulting the GNU project mailing lists.

On a more practical level, Moonraker asked how to configure Ubuntu so that he could write Japanese characters with his English keyboard. Shashank Sharma provided a list of links from the Ubuntu community help Web site -- but most of the information they contain applies to other modern Linux distributions as well.
47,035 characters, one guy who doesn't read the language
Andy had almost the opposite problem: he picked up an Asus Eee PC at a good price -- but it was localized for "Chinese, which I don't read. Linux and OpenOffice.org and Firefox as well as everything else are in Chinese. Any help on how to load an English version of the software onto this machine?"
Proopnarine provided a link to an Eee users' HOWTO on the subject, but he and user Lin agreed that the simplest and best solution was to install another Linux distro from scratch, using a USB-attached hard disk or CD-ROM. Sid Jackson supplied a step-by-step guide to that process, which requires knowing how to get access to the Eee's boot menu.
If it's Saturday, these must be unanswered questions
Fresh from his Eee-saving wisdom, Sid Jackson needs help connecting his Linux PPTP VPN client to a Microsoft VPN server. Got the answer?
No? Then maybe you can help Raj. He's writing a custom boot-time application that needs to call xmessage when there's an error. It works fine when run manually, but not when run at startup. Know why?
Speaking of execution, smlefo needs some definitive info on how shell scripts get parsed. Most start with the "hash bang" line that dictates what program should execute the script, like #!/bin/bash. But exactly what's legal there and what isn't remains a mystery. Can you solve it?
Finally, don't be depressed if you lack the encyclopedic knowledge to answer the aforementioned programming problems. You can still feel good about yourself by giving some advice to sonicblaze about his search for an audio loopback tool. He needs to tap audio output from one application and pipe it back out to be captured by another. And if that isn't enough, he needs to do it on a virtual machine. Quick, share your answer now, before he adds yet another wrinkle.
That's all for this week. Remember to post your answers to all of these questions by visiting the linked thread -- not by leaving a comment on this story. And it never hurts to take another look at the forum guidelines before you write.
