The war over 1-Click is over. Amazon won. BN.com is still open. Nobody cares any more.

For a related topic, see how the League for Programming Freedom got their panties in a bunch about Apple, calling for a boycott of all Apple products. They later rescinded that boycott, except their about-face took less than a year.

I hear the rainforest is still in need of saving, if you'd like a cause celebre...

% cat README | less

That has surely got to be a prime candidate for the useless use of cat award. Good advice otherwise...

Here is your useless use of kill -9 award.

while read a; do echo "$a, go away or I will replace you with a very small shell script."; done < /dev/people

/.ers know that real men use 'kill -9' to do this.

Only real idiots use kill -9.

what good is that when the spammer lives in a country that has no laws against spam?

Ironically for Yahoo's involvement in blocking spam, I was recently forced to switch my mailing list subscriptions from my Yahoo account because Yahoo's servers are considered insecure and some mail servers tag Yahoo mails as possible spams...

for ip in `cat ip-addresses.txt`; do whois -h whois.arin.net $ip | grep 'Country:' | grep -i us | wc ; done

Dangerous backticks, as well as what looks like a useless use of wc -l. I am assuming you want to count the number of times "us" shows up, which can be done easier as well. It shoulda been written something like this:

while read ip ; do whois -h whois.arin.net $ip | grep -ic "Country: \+US" ; done <ip-addresses.txt

Fun fact: I show up as Holland although I'm from Denmark. Dutch != Danish, damnit!

Here you go..
This is also a useless use of wc:
$ grep -cxP "" ChangeLog-2.6.3

[tom@hal tom]$ cat pmdexport.xml | wc -l

[tom@hal tom]$ wc -l pmdexport.xml

An extra pipeline => control of energy supply

cat /dev/sda1 | cdrecord

UUOC. Instead,

cdrecord < image.iso
cdrecord < /dev/sda1

That'd be a useless use of cat. Simple "strings < filename" would work. Probably don't even need the <.

Here's your UUoC award.

With karma to burn, I would like nothing more than to congratulate you on your achievement of the Useless Use of cat Award.

though my hardware that i'm taking isn't exactly computer related, i'm just taking my(i'm supposed to be fixing it, which i guess i did already but i can't know for sure since i don't have tapes for it) grundig tape player(NOT c tape player, this one has tubes and all, and jury rigged line in, for hooking up to c64/lpt-dac whatever). pics are at here

and then i'm taking my camera, 'canon still video camera', that saves the stills on a video floppy disk(kinda hard to find them, the video is afaik saved in straight analog form on the disks too.). 50 bad or 25 better(interlaced) pics per disc.
a piece of totally pointless technology :P.

one irc-friend is bringing an alpha..

still, the more important thing is the people.. as this doesn't lure 14y cs 'vets'... too bad it's a little too cold for the right style scene bonfire outside(i don't know though if theres even proper forest near enough for it, no sense making it somewhere where you can drive because coppers are sure to come and put it out.)

not to mention that UI changes are pointless anyways with modern day's customizability, who cares if the mouse cursor is big honkin billy face or the clock is bigger if they can be very simply added to older systems as well? nobody except people who think that makes their system honkin faster and preorder it because it's so cooooool. it has been pointed out earlier that these screenshots running around the net could have been pretty easily generated with windows xp, or 2k, or christs sake even with win98.
