Missle guidance software using, say, gyroscopes is straightforward.
But this software is at least 100 times more complex. It has to detect missile launches on the opposite side of the globe and work out whats heading towards you, using satellites; work out which are decoys; then fire your missles to hit the incoming missiles. You then have to hit the incoming missiles travelling faster than the speed of sound.
Hitting a bullet with another bullet is about the complexity cinvolved.
Transmitting emails using PGP is one way to keep your information private. Encrypting disks just adds to your privacy by making personal information private as well.
With all the litigation thats going on, including raids on Kazza & IndyMedia servers, keeping information private is a serious concern.
Many of the neetkooks have symptoms of personality disorders, particulary the B cluster of symptoms - antisocial/psychopath, borderline(psychosis/neurosis), histrionic and narcissistic symptoms.
Sollog seems to be running a borderline personality distortion campaign
"BP Distortion Campaign - when a BP deliberately tries to convince family, friends, community members or business associates that the Non is the one who is sick, was abusive, lied, was violent, etc. May involve false accusations of domestic or child abuse. May involve ' setting up' the Non to be charged with almost any crime."
I have a relative who works in a psych hospital who deals with these people every day. Theres a whole ward of people who think they're God/Jesus.
There are some recent technologists, but I think others have made great contributions to computer science:
Charles Babbage - inventor of ther difference Engine
Ada Lovelace - first programmer
John von Neumann - random access macines
John Backus - Fortran, BNF, compiler design
Don Knuth - "The Art of Computer Programming", algorithm design
as well as McCarthy & Alan Robinson(AI), Dijstra (structured programming, semaphores), Hoare (CSP)
I'm using 4.1 (its not a production release yet) which has subqueries, proper joins, and unions.
Its the first version which is even remotely acceptable. Coding without subqueries is very frustrating
Views, synonyms and referential integrity (foreign key constraints) would be very nice too.
When I find out why VHS became more popular than technically superior Betamax, I'll figure out why Mysql is more popular than Postgres.
- Over 750 requests/second on 29
- servers average >20 requests/second each (Yes I know some are not http servers) . Compare that to some commercial solutions.
- commodity hardware
- squid for cacheing/load balancing, feeding Apache
- multi-tiered archtieture
- dual Opteron for the master mysql database

WiFi Bridging?
·
· Score: 3, Informative
A commercial 14dB antenna is high gain for wifi and should work for miles, so the dropouts you are experiencing are very strange. I suggest starting a packet sniffer like Ethereal and seeing what happens when dropouts occur.
If you can use a standard outdoor wifi antenna (made by dlink etc) bolted to a bracket, commercial pigtail and limit the RG48 length you should have no problems. You can reduce cable length using power over ethernet.
I'd put an access point at both ends (rather than wifi cards) as it will effectivelty do the bridging for you
If you
- are running two or more CPU intensive tasks (multiple httpd proceses, database servers)
- have an SMP capable OS (eg linux)
of course multpile cores are an improvement.
Its well known that
- Google has from 50,000 - 100,000 servers
- they run linux on "barebones" machines (1u cases with no sides/top) to cut costs
- This paper by Google engineers documents how Google's distributed, fault tolerant system works.

Yet another reason to use Pretty Good Pricacy, and encrypt you disk partitions.
David Parnas predicted in the 1980s that software for missile defence was impossible to test.

Do appear not to understand the difference between random access machines and random access memory

Implementation details of the Google File System can be found in this paper by Google engineers.
This maybe a bit offtopic, buyt I've written a 802.11b wifi HOWTO to get cheap wifi working with linux.
With Spamassassin, you need to train/fiddle with rules after installation.
The Postfix Spam Controls have reduced my spam by 95% without using compex spam filters like Spamassassin.
This shareware spam filter made Nick Bolton $3.5 million in 2003 and now he employs 28.

- they have given the community Java, Open Office, NFS, & RPC. While Java is not strictly open source it is widely used.
- Sun's John Bosak created XML.
- they still make most of their money from hardware and services
- just about all the machines they sell can run linux (and bsd)
I used to get this sort of email, but I've set up Postfix as my MTA to reject all zip, exe etc files that may contain viruses.
At the risk of damaging my karma, any post promoting HawkinsOS is a troll.
These asyncronous computers are implementations of data flow computers.
The problem is that the first implementations were very slow.
