The former soviet union built airplanes (MIG-somenumber, I think) with (radio) tubes instead of sillicon. It was designed to be immune against EMP. A tube does not die if it is hit by EMP, maybe there are some sparks inside, but that's all.
So at least those planes should be immune against that microwave gun. And perhaps even circuits based on germanium instead of sillicon, because the microwaves are tuned for the wrong material.
Yet Another Variant of the old "Get DSL/Cable performance out of your old 14.4k modem" story? Sorry, but "plus 400% data rate" stinks. Show it in the field with a few thousand parallel users and I'll believe it.
I'm working since the previous millenium (hehe, ca. 1999) on a complex, CGI-based application. Some day, I "invented" the "ultimate" printf() debugger for CGIs - a simple program that waits for input on a TCP socket and writes it to the screen or a telnet client on a second TCP port. The CGI to be debugged just opens a TCP connection and printf()s the messages into the TCP socket. All nicely wrapped in a small module, providing a single function named debug().
I never needed anything else for my job.
Back in those old days when Borland Pascal 7 was new and cool and I went to school, I was happy to have a debugger that could single-step into my Assembler code. But now, I have no more need for PEEK and POKE.
If you have high EMI in your environment, copper cable and radio will have much trouble, no matter at which frequency they work. You need to use either sound or light. Sound (ultrasonic) is very rare in networks (at least I do not no any solution for IP over ultrasonic), light leaves two possible solutions. IrDA (at any speed) and some mirrors, like someone else already proposed, or optical fibre. If you need to move your devices, you have to use IrDA, maybe with mirrors at the ceiling or other optical tricks (like lenses). Otherwise, just stick with plain old ethernet over fibre.
The guys and girls of the german c't magazine combined toms rescue boot disk with F-Prot for Linux and pressed it onto a CDROM shipped with the issue 13/2002. You can order this issue for 3 EUR + shipping (1 EUR is round about 1 US $).
If you can get internet access with that CDROM, you can even update the scanner and the data files. (And as a nice bonus, you get 600 MBytes Freeware and Shareware.)
Anyone with a faster penguin ? Perhaps a Tux sticker on the NASA space shuttle ?

USB- or PS/2-Powered Hubs

Portable Hubs?
·
· Score: 1
Have you tried to search for an USB- or PS/2-powered hub ? They may cost a few bucks more than a standard wall-plugged hub, but they do not need a separate battery, they just slowly suck out your Laptop battery.
(Please note: I do not think of USB Hubs, but USB powered Ethernet hubs.)
Here in Germany, we have several TV magazines and films with optional subtitles using teletext. I think that could help. DVDs with subtitles may do the trick, too.
\000 - Putting a zero byte in a filename will break any program written in C.
'/' - A filename with an embedded slash will be unusable except by programs that walk directory contents very carefully.
Are you sure you can do this ? I'm nearly sure you can't, at least not without manipulating deep within the filesystem (hex editor). The libc and kernel APIs won't let you do this (at least, they shouldn't let you do this).
white space - Filenames with embedded white space work with most basic system commands, but will break shell scripts that aren't prepared for them (which means most shell scripts).
Agreed. White space not only breaks shell scripts, but sometimes even applications. I remember rewriting large parts of midnight commander's config files because it could not handle white space. Those guys writing the mc simply forgot to use quotes in most external commands. I don't know if it's already fixed, I haven't updated my Linux for a long time.
Ask the Experts at http://selfforum.teamone.de. It's a german forum, but most people there can read and write english as well. The SelfForum is related to the famous SelfHTML (at least here in Germany, it is famous). Just copy and paste your question there.
They released it just in time. I have ordered a new server, it will be delivered not befre I've downloaded the new slackware. Now guess which OS will run on that machine.
http://www.heise.de/ct/ftp/projekte/flasher/ -- Hardware, Layout, Software, everything you need for flash EEPROMs up to 4 MBit. It's an old project based on an ISA card with DOS software, but no one stops you writing a linux device driver for it.
Look at the Universities, where Linux "grew up". My "University of applied science" has several Linux pools, most of the prof's and assistants are using at least one Linux machine on their desktops, and most laboratories have Linux machines.
Why? Linux is cheaper than thousands of MS licenses.
Support? Ask a student!
Cost of Support? None for Profs (or good marks;-)), a beer for friends to install a recent linux.

fli4l plus OPT_BOOTCD. You may also want to read one of the HOWTOs fli4l auf CDR or isofli4l.
fli4l is a german language project, but fli4l itself has also an english documentation.

I'm not related with Frisk Software except that I use their software.
