OpenBSD diskless install | Me in IT
Here is a recipe to boot OpenBSD (4.1) from an OpenBSD (4.1) box. This can be used to boot any machine that has no disks and supports pxeboot. The advantage is you save a little money on not buying hard-disks, but on the other hand, the "server" that serves everything must be always on.
Welcome to The UNIX Grymoire!
This page includes Bruce Barnett's tutorials on UNIX shell programming and various other arcane subjects.
Most of these tutorials were written form 1989 - to 1995 for The Sun Observor. The tutorials may still refer to information as "last month" and next month." The tutorials were planned to be put into a book, but Carpal Tunnel Syndrome make the book difficult to finish in the time frame the editor wanted.
These tutorials are Solaris-specific, and contained a lot of references to OpenWindows. Times have changed, but I hope the basic information will still be helpful.
These tutorials are written in TROFF. Converting them into HTML is not a perfect process. There are errors. The tables are ugly, and the indentation inside the shell scripts gets messed up. So I've made the scripts available in source format as well. However, the convertion between HTML, TROFF and plain text is not perfect, so there may be typos in the files and tutorials. In addition, the convertion is an on-coing process, and as I improve the conversion process, the tutorials may look better.
I'd give you my e-mail address, but frankly I think spammers should rot in hell. Therefore I'll give you my e-mail address in longhand form.

The Quick Reference Site - The largest collection of free Quick Reference Cards
by 2 othersThroughout the years I have collected a huge pile of documents that deal with almost every aspect of software development. The purpose of this site is to centralize this information and to make it available to everyone who may need it or shares my passion on this subject. There are still a lot of documents in my "archive" that I like to share with you all.
At the moment this site represents only a fraction of what I want to provide, so a lot of work still needs to be done. As a result, you should consider this site as a work in progress. I'll try to keep you updated on the most challenging, powerful and continuously evolving software technologies of the moment. I hope that especially Java and C++ fanatics (like myself) will find some valuable information over here.

The C10K problem
by 3 othersIt's time for web servers to handle ten thousand clients simultaneously, don't you think? After all, the web is a big place now.
And computers are big, too. You can buy a 1000MHz machine with 2 gigabytes of RAM and an 1000Mbit/sec Ethernet card for $1200 or so. Let's see - at 20000 clients, that's 50KHz, 100Kbytes, and 50Kbits/sec per client. It shouldn't take any more horsepower than that to take four kilobytes from the disk and send them to the network once a second for each of twenty thousand clients. (That works out to $0.08 per client, by the way. Those $100/client licensing fees some operating systems charge are starting to look a little heavy!) So hardware is no longer the bottleneck.
In 1999 one of the busiest ftp sites, cdrom.com, actually handled 10000 clients simultaneously through a Gigabit Ethernet pipe. As of 2001, that same speed is now being offered by several ISPs, who expect it to become increasingly popular with large business customers.
And the thin client model of computing appears to be coming back in style -- this time with the server out on the Internet, serving thousands of clients.
With that in mind, here are a few notes on how to configure operating systems and write code to support thousands of clients. The discussion centers around Unix-like operating systems, as that's my personal area of interest, but Windows is also covered a bit.
