All languages are susceptible to security problems.
However C and C++ (and a few other languages) are susceptible to buffer overflows - where it is common for bugs to cause "execution of arbitrary code of the attacker's choice" - this is BAD.
There are saner languages where such things aren't as common. While Lisp can be compiled, AFAIK it is not inherently susceptible to buffer overflows. OCaml isn't susceptible to buffer overflows either and is in the class of C and C++ performance-wise.
"arbitrary code of the attacker's choice" can still be executed in such languages, just at a higher level = e.g. SQL Injection. Or "shell/script".
However one can avoid "SQL injection" with minimal performance AND programmer workload impact by enforcing saner interfaces e.g. prepared statements, bind variables etc.
How does one do the same thing with respect to buffer overflows and C or C++, AND still have things look and work like C or C++?
Yeah, I wonder how fast google's machines really are.
I believe recently some guy at Google mentioned running something that took weeks of total CPU time but only a few minutes real time. Or something like that. Anyone got the reference?
They can probably make money just by figuring out what the "dumb sheep" "investors" are going to buy next (most of them are dumb sheep).
When you talk about governments and countries, TCO/costs should be looked at differently.
Even if OSS costs more than MS to run it should not be the main consideration. A country should also see how much money LEAVES the country.
This is why some smart countries/govs are still picking certain OSS even IF the TCO is higher. Even if you pay a bit more for services and support, the money goes to YOUR citizens and it comes back to you via taxes. D'oh...
Don't ever forget it is PUBLIC money you're spending.
If the UK Gov rarely cares about these things then the UK is pretty much screwed.
Brute forcing is like what some alchemists did - try all the combinations and get a result.
It's more interesting if you can find a "summary" or new point of view.
Also, IMO a solution (not talking about proof) that is magnitudes larger than the problem is not very good, and that a good solution is like good "compression".

Use Perl. Then you can keep the code to yourself. Heck how many people do you think will claim it's theirs?:)
You can think without a language, most times the language is just commentary. Of course the commentary is often fed back to stimulate further thought, or used for indexing.
For example if you are deciding between having an apple or an orange, you don't have to think in English for that.
I suggest you learn another language and get used to the idea of having thoughts you don't have words for.
Otherwise your mind might get lazy and hardly ever come out with thoughts/concepts you don't have words for.
Nonono. The Jesus story is reference to God putting himself in a quantum-like superposition in his own creation so that the observers (having also been put in a superposition - "made in the _image_ of God") by just believing or having faith can actually influence their final place in the ultimate interference pattern- patterns of light and darkness.
Coz despite all that our ancestors still reproduced.
And that's all that's needed. Which is why I find it strange that some scientists can say that we behave in a particular way because it is evolutionarily advantageous, "selfish gene" etc etc. e.g. male peacocks having fancy tails because it's a sign of health to the female peahens.
Such BS. In the milder climates almost anything goes due to the abundance of energy and raw materials. Go to the harsher climates and then you can see that a creature behaves a certain way because if it didn't it'd be dead in 5 minutes.
No. They went off their rocker more than 3 years ago when they designed the P4 and went for GHz for marketing reasons and not engineering reasons. That said the P4 actually served them well for a number of years, but they didn't get off at the right station...
I remember Intel talking about 5-10GHz CPUs. They were probably taking a bet that the process and material engineers would save them.
I'm sure they realized they lost the bet when the Opterons/Athlon64s started spreading their wings and actually flying, but when you have multi-billion dollar fabs, commitments to partners, it takes a while to turn the ship.
If you observe, they've canned a lot of stuff and changed their product milestones/announcements.
They just can't tell Dell, forget the next bunch of P4s, we're going to go Pentium-M NOW (even though we haven't got it fully buzzword compliant)!
Any idiot can realize the Prescott was bad news ONCE it was testing. But by then it's just too late.
AMD has a window of opportunity till at least early 2006. As long as they don't screw up! They better use overwhelming force if they want to win. It's not an easy battle. Intel is no pushover.
I mean - what's there to prevent Intel doing the same stuff as AMD? e.g. Pentium-M with memory controller on CPU?
Meanwhile I'm really curious about the new Intel SMP server chips. What are the power consumption and cooling requirements like?
I was referring to this: "That it's the Democrats who control Broward county, and all its absentee ballots "
Haven't you seen Wrestling on TV before? You have two teams. You also have two commentators. Each commentator will ALWAYS support their wrestler/team NO MATTER WHAT. Even to ridiculous extremes. If their wrestler does it it's OK, if the other wrestler does it it's cheating etc.
Then you have the fans, who a diehard supporters of their respective teams.
This round it looks like most of the audience actually thinks its real wrestling!
Didn't you mean to say: "What does that have to do with the disappearing championship belt"?
In the US the candidates need to come up with quite a lot of money to have a chance of winning - no money = very low chance of winning.
More often than not the money comes from lobbyists/corporates. So out of a large number of Republicans and Democrats, the corporates can just pick the few Democrats AND Republicans that will do what they want. So it doesn't matter as much to them which side wins - as long as it's their candidate who wins.
It's like a magician giving you a hand of cards to pick from. The cards have already been picked!
Well you're stupid if you keep betting and never realize you have a poor grasp of statistics.
It's not stupid if they bet when the jackpot accumulates a few times. Or they've figured out how the numbers are generated before betting - has happened before (I think some lottery used a computer to generate the numbers...).

The big difference is current popular wireless networks are a lot easier to jam than current popular wired networks.
And that's good enough reason to not use it for anything important.
What do you think of
;).
So maybe they already have evolved it. Maybe it's just not as developed (or the countermeasures have also developed).
Who knows maybe that's also part of evolution - which is why certain things evolve the way they do - because it's needed in the future - so it looks like creation to creationists
Over billions of years animals getting a prescient gut feel - "this mate is not for me/ this mate is for me", so there might be a prescient sense. However you have to take into account the other animals who also have prescient gut feel out to eat your descendents too.
Coz AFAIK all the animals are kinda in the same boat and descended from the same ancestors, so any such sixth sense could be just because they're all linked - destinies intertwined. You might not get the gut feel that something is about to eat you if overall it's part of the big plan for you to be eaten...
Maybe we won't be able to be prescient with aliens from another world - won't know if the aliens are "staring at" us.
BTW if you're talking about psychic powers, I don't see why one should assume the "organs" involved should all be in this world. The interfaces maybe, as is the scientists are still scratching their heads over how the brains work etc.
When I last checked scientists don't even know what 90% of the universe's mass or energy is. So the stuff we consider normal is actually abnormal.
Also: scientists have NOT explained the very FIRST observation each of them ever makes- consciousness/self-awareness.
e.g. recursive future-sense.
Yes - it would have been obvious to anyone in that field.

AFAIK that's when the passwd file is corrupted or missing- then according to the O/S your chosen user account doesn't exist.
Did you include the DVD burner whilst doing your figures? How many DVDs can you burn on your burner before you need a new burner?
200GB HDDs are a pretty good deal.
I use one of those caddy+bay thingies for my internal HDDs so I can add/remove them easily. They come with fans etc, for about 10-12USD.
I'm waiting for the SATA equivalents - SATA can theoretically support hotswap...
Because they are mainly bought by the stupid or desperate?

They said they've got it to 95% accuracy. But that's for rat samples.
;).
What if it only works for 95% of the people who aren't really exceptional mentally.
Or maybe it only works for narrow-minded people
Any comments on the recent news on the artificial hippocampus (link #1 link #2)?
"Opteron 1xx: K8 core, dual-channel memory, 1 HT link enabled (for 1-way)
;). Thanks!
4 _4 _slides_r31_nsn.pdf
Opteron 2xx: K8 core, dual-channel memory, 2 HT links enabled (for 2-way)
Opteron 8xx: K8 core, dual-channel memory, 3 HT links enabled (for up to 8-way)"
So they are probably the same chip, just with HT links disabled for 1-way or 2-way chips?
I was a bit lazy to look it up myself
"I seem to recall the Opties are about 105 million transistors"
From: http://www.intel.com/design/itanium/itanium/
Itanium = 25 million transistors for CPU, 300 million for cache.

Itanium 2: 410 million transistors!
374mm^2 die size (130nm)
Opteron = 194mm^2 die size (130nm).
Hmm. Itanium seems to have almost twice the transistors per square mm.
