I set my mail server to tag emails rather than block them (move to spam folder on workstation), so i see some interesting things...
When i first tried it 6 months ago, it magically worked, 99% of spam ended up in my spam folder.
Now the blocking ratio is down to about 10%... and here's why. There are 3 MX records for us: A - linux server - MX = 10 B - msexchange server - MX = 20 C - isp's server - MX = 30
messages delivered to A are tagged (if spam) and forwarded to B. B exists in the MX records for redundancy. C is used because A and B are on the same site.
What i'm finding though, is that spammers send emails to B or C. When A receives the email, it has come from B or C, not the original spammer, so suddenly the blocking doesn't work anymore.
dammit.
It can only work if everyone in your MX record list does it, and my isp is the biggest in Australia so it's an awfully large machine to move.
I have tried adding in more dummy MX records, so that A is first, middle, and last. That seemed to work for a bit but not for long. I might have more success adding different ip addresses for A and peppering the MX list with those... but it's a bit messy.
That's not as dumb as it seems. If they put a ban on downloading anything racier than an exposed breast via ipv4, 90% of internet traffic would be on ipv6 within a week.
and a server that does these things to spammers (eg unknown users sending email): 1. attempt to exploit all known vulnerabilities on their computer. 2. connect to their address book, and forward each email they send to all the addresses in it. 3. if all that fails, pretend to accept their email but don't actually send it.
the above could be covered legally by a TOS statement nailed to your gate (IANAL:)
of course watching 400 little tiny yappy bitey dogs snapping at their toes would be a lot more fun.
people say this, but i've had nothing but good fortune with mine. I attribute this to several factors:
. I don't overclock it, and have never overclocked it . I don't run Microsoft software on it . I use a good quality power supply . I keep it cool. Not water cooled, or super fans. it's just got the oem fans in it and a few other case fans to evacuate the hot air. (no probs even in ambient temp of 40 celcius) . quality memory. . dumb luck.
If you _ever_ overclock a mb/cpu, you risk damaging components. permanently. It might not show up straight away though.
That being said, the revision after mine had a documented (not by abit afaik though:) problem with an out of spec capacitor. Replacing this improved reliability for some people.
I've been running 2.5.xx on my home server since xx was >30ish. not really by choice either. 2.4.xx (for all xx) is grossly unstable for my combination of hardware. I got ide irq timeouts which brings the machine crashing down often before it had finished booting. It would run in uniprocessor mode but what's the point of that!!!
I have one problem with hostap (wireless access point drivers) and my sound card sharing an interrupt which causes a crash occasionally, but if i don't load the sounds drivers it never crashes.

I'm running the latest NVidia drivers with 2.5.65 and they work fine (after patching of course). The patches can be found on the internet if you look around.
'odd' is just a property of any number not divisable evenly by 2, so as you say, "all primes except 2 are not divisable evenly by 2."
to extend that...
all primes except 3 are not divisable by 3. all primes except 5 are not divisable by 5. all primes except 7 are not divisable by 7.... all primes except x are not divisable by x. (where x is prime).
that is by definition though, it's not a proof.
odd, (and for that matter, evenly divisable by 5 or 10) is only visible in our normal number system because it is base 10 and 10 is evenly divisable by 2, 5 and 10, so we can tell at a glance for a number printed in base 10.
if we used a base 3 number system, or some base divisable by 3, all numbers divisable by 3 would be instantly recognisable too.
That's a tricky one... if the other car wasn't there at that exact time, he might have made it home without incident.
Has this ever happened to you? (you = whoever is reading this)
If so, you're _exactly_ the same as Reggie, you were just lucky enough not to hit anyone.
If you're going to put this guy in the gas chamber, make sure you throw in every other asshole who has ever jumped in a car with their blood full of alcohol.
I used to work as an engineer in a manufacturing plant for one of the larger computer companies. We would be assembling PC's from components, which would be the first time the boards would be powered up for any length of time. If a cap was going to pop, it would generally do it in the first 10 minutes or so of testing. Sometime's because they were installed backwards, sometimes because they were fractured and a bit of moisture had leaked in, and sometimes just because. When they pop, they do so with a fair bit of force for their size.
This is why you should wear eye protection when you peer over an open computer, especially a newish one!
As i see it, the main difference between a rocket and a missile is payload. I can't see that it would be difficult to add a nasty payload to an otherwise innocent rocket. I hope they don't deregulate too much...
You give me any large prime number (you make sure it's prime:) and i'll tell you all the factors within a few seconds. i'll even sell you the code to do it for a mere 1 million dollars ($US of course... my currency isn't worth anything anymore:)
Tweaking the rules.ini file kept me playing the game for a while after the original novelty had warn off. making harvesters mostly invicible was a variation that was great in multiplayer (for a change anyway). I think later incarnations (red alert etc) added this as a game option.
Tweaking also meant we could change the game just enough so that the normal strategies (light tank storm etc in later incarnations) didn't work so well, and we'd all have to invent new ones.
The map designer in redalert was also great! it added so much value to the game in multiplayer mode.
I have found my RBL rules becoming less effective as spammers are sending mail to lower priority MX records, which are run by upstream ISP's that don't have RBL filtering in place. Consequently i don't get to see the originating ip address in a form that can be filtered on.

why is the 11Mbs 11Mbs, while the 10Mbs is only theoretical? Maybe all theoretical limits are created equal, but some are more theoretical than others.
i'd have thought that there's enough packet overhead etc on 802.11b that once you strip all of that off their probably just about matched.:)
