I've talked about Linux From Scratch before, and I like how it gives you just what you want, compiled how you want, by your system, for your system, but it doesn't actually give you a very useful system in the end.

It was looking like I'd get to call a l337 h4x0r to the carpet and lay some smackdown at work, but unfortunately I had a prior commitment. Too many things to do, not enough Daves to go around. It's the story of my life.

I'm on my Linux From Scratch kick again. Unfortunately, compiling a complete workstation from scratch takes a really long time (the systems that benefit the most from it, namely low-end P2s, need close to a day to compile everything if you want X, KDE and GNOME and some common apps) and requires you to type a lot of awkward commands that are easy to mess up. The upside: Messages like, "I did my first LFS on a Pentium II 18 months ago and it was by far the best workstation I've ever had," are common on LFS discussion boards.

Optimizing Linux. I found this link yesterday. Its main thrust is troubleshooting nVidia 3D acceleration, but it also provides some generally useful tweakage. For example:

Here are some odds and ends, since I've gone nearly a week without talking computers.

OK, here's the situation. I had a Linux box running Squid, chugging away, saving us lots of bandwidth and speeding things up and making everything wonderful, but we wanted numbers to prove it, and we liked being able to just check up on it periodically. Minimalist that I am, though, I never installed Telnet or SSH on it. And besides, I haven't found an SSH client for Windows I really like, and Telnet is horribly insecure.

I felt downright awful yesterday, but it's my own fault. I remember now why I don't take vitamins with breakfast. Very bad things happen.

I've talked about Squid before. Squid is a caching Web proxy, designed to improve network speed and conserve bandwidth by caching Web content locally. How much it helps you depends on how you use the Web in that particular environment, but it's usually worthwhile, seeing as the software is either free or costs next to nothing (it comes with most Linux distributions) and it doesn't take much hardware to run it. Don't use your Pentium-75, but you can deploy a standard desktop PC as a Squid server and it'll work fabulously, unless you've got thousands of PCs hitting it. For a thousand bucks, you can seriously reduce your traffic and chances are it'll pay for itself fairly quickly.

It's a little late, but here's how Gatermann and I got a Web server running behind a Freesco-based router. Freesco, despite the name, is a micro-distribution of Linux (based on the 2.0.x kernel) that offers firewalling, NAT, caching DNS, port forwarding, a lightweight Web server, and print services on a single floppy. Requirements are minimal; it'd run on a 386 with 8 megs of RAM, a floppy drive, and a pair of NE2000 NICs. For performance and ease of setup, I recommend a P75 (or faster, but a P75's overkill; the main reason to use it is to get PCI) with a pair of PCI NICs and 8 megs.

My research yesterday found that Mandrake, in an effort to get an edge on performance, used a bunch of controversial Apache patches that originated at SGI. The enhancements didn't work on very many Unixes (presumably they were tested on Linux and Irix) and were rejected by the Apache group. SGI has since axed the project, and it appears that only performance-oriented Mandrake is using them.
