We use Postgrey to filter the spams out.
It works wonderfully even without additional filtering (blacklists, for example.. Which we do still use, though).
Postgrey is a grey-list system por Postfix (for a description on how it works, click here), and there are probably other good greylist filters around.
We've had (like everyone else has) massive amounts of spam going through Spamassassin, our server was down its knees all the time.
Now the machine is typically 95-98 percent idle and the spams we receive (remember I've said we use blacklists aswell) is only the ones which come from our intranet (from hijacked machines we quickly disable when discovered).
That tool saved the day.
Eventually those bastards will have a way around it, but for now it works very well.
AMD processors are nice as long as you use them at their nominal clock.
I've had bad experiences overclocking AMD processors (considering extended usage >6 months and at 100% load) with proper refrigeration. Unfortunately those processors tend do break (with no prior warning) eventually. What's a pity, since they overclock well.
There are worse processors in this aspect though, the UltraSPARC (at least the "I" models) may die after few years user nominal clock and standard refrigeration.
I've never had problems overclocking an Intel processor. Perhaps because they already irradiate lots of heat (and are built with that in mind), those processors seem to have a good resistance to overclocking and, when things are going bad, they tend to become unstable (and more sensitive to temperature) instead of just dying immediately.
Oh, great. It does require hardware extensions for virtualization. -- For some reason I don't feel like upgrading the whole server park here just to migrate from Xen to this thing.
And what if I desire paravirtualization (because it's faster and cleaner) even with such VT-enabled processors available to me?
IMO, unless this technology envolves into something Xen-alike, it was bad decision to include it into the kernel tree.
Uh? In Amigas the nvram was used for the realtime clock and as a playground for certain annoying viruses.
From Amiga OSes up to 3.1, the OS was mostly located in ROM, what speeds up booting.
Unfortunately the floppy disk access was very slow, so booting the OS wasn't as fast as it could be.
Who cares if we have ridiculously rich people? What does it matter? It doesn't stop you from achieving your goals, you have to work to get there and earn your way the same. Just because there are enormously wealthy people doesn't mean you're prevented from acquiring wealth yourself. in fact, it makes you all the more likely to be able to get rich. These people if they want to stay wealthy, or grow their funds, must use it in some way. Maybe just earning interest in a bank, maybe investing in startup companies. Either way that money becomes a tool banks/companies can use to generate more wealth, and you can get in on that.
What you wrote here is an oversimplification.
First, if you're poor, your income goes mostly to survival expenses, thus not much remaining for anything else. Well, even if you're mid class you'll probably have the rest of your income going to pay your own house during 20-30 years.
Second, the money you manage to save will perform poorly (percent-wise) while invested in a bank, compared to the massive investiments from the rich people. With lots of money you manage to get better interests and conditions from the banks, likewise while borrowing money from a bank. Being a poor guy, the banks feel they do a favor to you, and provide their services to you accordingly.
That decrepit arcitecture is the fasteest consumer hardware platform in existance.
I agree.
If Volkswagen had a massive consumer base to justify producing an old-style Beetle model capable of reaching 400km/h, you bet they would so.
But you see, despiste such an interesting market for x86 processors, how many companies are able to invest massive amounts of money in order to make a x86 speedy processor?
Compare this to the development money spent in UltraSparc T1. Geez, I bet those chinese guys spent a nickel to develop that MIPS-based Godson processor.
My point is: we could have much better and cheaper processors weren't we tied to the x86 architecture.
>> What happened to the RISC philosophy?
> We decided we wanted cheap, fast hardware, and we decided the philosophy made more sense at the software level.
Uh... More likely you folks have decided you want to run DOS and Windows.
Since both were (are) locked to the x86 ISA, it gave this decrepit architecture a reason to live.
That's one less third-world country I have to add to my server's firewall blocking rules!
Funny thing you mentioned...
On the other hand, most (90% i guess) of my spam advertise services/products which the contact is someone in the U.S. (a so-called 1st-world country), despiste the fact I do not live there.
Considering this, I would say the root of the problem is not really those poor countries.
"develop capabilities, plans, and options to ensure freedom of action in space, and, if directed, deny such freedom of action to adversaries"
This is what the government SHOULD be doing. Defense agencies should always be "developing capabilities, plans, and options" for every single possible threat. That doesn't mean we need to build a space cruiser, but that does mean that having a plan to build one is not a bad idea. Hell, having a plan to invade Canada on hand is a good idea. Expecting and being prepared for the unexpected is what intelligence and defense agencies are there for.
This kind of attitude like yours is the very reason no one in Earth likes the U.S., and it's going to be a self-fulfilling prophecy.
Ooooh, and without a paper trail, how do you prove that you did in fact vote, if your salary payment is suddenly stopped? Something tells me that mandatory voting may be the law, but it is not enforced.
"Ooohh" yourself.
There is a paper you receive when voting which serves as such proof, and that paper is required when opening a bank account, for example
I think we found the real story here: 125 million out of an estimated 186,405,000 (2005)?
THAT'S A HUGE VOTER TURNOUT!
HOW DO THEY DO IT?
That's very simple: voting is mandatory in Brazil.
If a person doesn't vote (and does not fill the justification form for not voting), he/she loses the right to a number of things including opening bank accounts, getting a new passport, etc... And if you're a public servant, you immediately stop receiving your salary.
I live in Brazil and the news have been reporting this for months now.
So you're already poisoned with the one-sidedness of the media coverage. Nice excuse, though.
So, obviously, your fairness is due to the fact you live outside the US.
It's not only the child porn, but there have been other issues, like people advertising place where others can buy drugs.
Well... they know the DAMNED PLACE and they still WANT MORE INFORMATION?
Perhaps because they want their IPs, since not everyone puts their address with zipcode in the messages.
Google on the other side have been refusing to help for months just telling "our servers are in the US, we can't do anything", and the Justice telling "You are Google too, talk to them and get this information", and they just refuse.
Ever wandered why Google is percieved in a much, much better light even in geek communities, where trust is hard to earn? Now you know.
Bending over for the Chinese is much more acceptable, indeed.
Oh, sorry -- I forgot, there's over a billion potential consumers in China.
I like google, but they are not helping with this at all.
That's why I like them.
Exactly, now go to your backyard, get some beers and wave a big US flag so show them who's the boss!
Instead we have a teenage constitution and historically widespread corruption on all levels of government, besides the people's distrust in all institutions from all segments of society.
Ah, our little revolutionary!
Ranting, complaining, pointing fingers at everything and everyone.
Obviously, even when other countries are wrong, Brazil is even MORE wrong.
The U.S.A. could drop an A-bomb in Sao Paulo but--hey! We are a country with homeless people, thus we deserve that!

I wouldn't overclock an AMD (Score:1, Flamebait)
Nice to see some bigots with moderation points.
"Flamebait" != "I disagree"
They tend to break when overclocked, and yet they overclock "well"?
I don't think that word means what you think it means.
Yes, they overclock well until they break.
Next time, try understanding the context.

"Why Do Computers Take So Long to Boot Up?"
Yes.
Uh? In Amigas the nvram was used for the realtime clock and as a playground for certain annoying viruses.

Unfortunately the floppy disk access was very slow, so booting the OS wasn't as fast as it could be.
30 seconds! When I was a kid computers took 5 minutes or more to boot. We'd have given our eye teeth for a 30 second boot time.
Oh, you sure must be old.
When I was a kid my computer took 1-2 seconds from power-on to prompt.
That was for 'The Americas'.
You mean North America.
I see no sign of any of those consoles here in Brazil.

All this is irrelevant, however, as the US has no notion of attacking its friends,
Countries have no friends.
Countries have interests.

Now I can finally dump that trashy Linux and KDE, and enjoy a full computing experience with my dual core-powered machine!
So does this mean Slashdot users will be flooded with ads for personal lubricants, hand lotion, and kleenex?
...
Why would a male, whose sexual life is limited to masturbation, want a personal lubricant?
Oh, wait... I don't think I want to know.
Had the Pope the audacity to start the Crusades many years earlier, the multitudes of Jews in Spain and Jerusalem could have been spared their lives.
The way you put this, almost sounds as if the native people living there did not matter much, when compared to the jews.
He is also working on breaking SHA1 and RSA encryption in a single processor instruction cycle.
move.l <key>,d0
That was easy.
I'm not sure it's possible in x86 processors though.

The fact it was an USA citizen who discovered Pluto doesn't have any relation with this, "of course".
