Slashdot Mirror

On first blush, this seems like a "look at me!" article. But I think the author does bring up some good points on methodologies used in fighting spam on a large scale. However, one thing that isn't emphasized is how little deliverable email he gets. It looks like it averages 5-10 messages per hour.

So the next question is, how would his techniques scale to a domain that processes 3.5 million emails per day and rejects 0.25-3.0 million spam emails per day. Plus, to reduce the risk of false positives, much of the spam is actually delivered to users. All delivered email has a spam score added to the email headers for the individual user to decide their threshold for filtering.

For those of you out there who are IT for domains that handle millions of emails per day, how do you handle spam? How many servers and how much bandwidth does it require?

If you're curious, I get 100 emails per day delivered and 78.2% of that is spam. Unfortunately, I've found that I can't rely on the spam score added to the headers by the aforementioned domain. My filter (k9, Bayesian) currently has a false negative rate of 0.49% and false positive rate of 0.00%. Yeah, that means I see a single piece of spam every two days on average. In reality, I'll usually get a surge of spam where on a single day I might get two or three pieces of spam, followed by a week of nothing once the filter has adapted.

For protection on the net, especially for usenet and web forms, I use disposable email addresses (ie: spamgourmet, mailinator).

How about a cache of their cache just to be paranoid?

The site seems to be slowing down, but the coral cache is going strong.

Seems a trifle slow..

I wonder why the story links don't use it BY DEFAULT? Just add .nyud.net:8090 after the domain name. Is that too hard?

Take it easy on the main server, here's the Coral cache...

That wasn't the paper, that was an article about the paper. The article is here.

I think the correlation the author tried to present had two variables that may be related but don't necessarily relate one for one.

Well it doesn't really matter what you think, because this guy actually researched it. His research is more important than your uninformed opinion. Not saying you're wrong, but I'm saying you don't know, so you cannot dismiss it.

People should start using the CDN (Coral Distribution Network) when making posts to Slashdot... The homebrew site works nicely through it.

as for the little box getting creamed. well, the front page is on the CDN, but the rest... not quite so.

All you young whippersnappers with your "dupe" stories from 2003 and 2004. Back in my day, we had real dupes. From 2001, when Pacman was being played on the streets of New York.

But seriously, check out the videos (Coral Cache link). They're priceless. (Edit: The videos seem to be offline -- does anybody have an archive?)

"That ghost's gonna catch Pac-man, gonna *$#@ him up."

This is a sound file with SteveJobs and Khan. I do not see the two as mutually exclusive.

Right now the coral cache of the Magic-1 is operating. But only the front page.

Amazing!

Yep, there is no chance this will get slashdotted, but in case it does, I think there is a mirror working here.

There is one big drawback, though. Users won't be able to install Service Pack 2, unless they integrate SP2 in the installation CD. And that's probably too much trouble for most users, who of course are better off buying a legal version anyway.

Yeah, that's way harder than using regedit to modify install files and copying the boot sector of the install CD to a new one...

Your friendly neighborhood slipstreaming advocate

Instead of posting the obvious joke about dupes, here's a link to the movie form the previous story. (Coral link)

Some of us are doing our part

Ouch - Coral Link gives a bad response right now.

Any other mirror links?

For those of you who have no idea what thermal resistance is, just think of this heat sink as "overkill" even for overclocking.

(for overclocking, power dissipation is directly related to frequency. 10% faster is 10% more power to get rid of and most processors will not go twice as fast anyhow!)

For those mechanical engineers who do packaging and stress and vibration analysis, aren't you glad this in not your project. The heat sink is not attached to the processor; the processor is attached to the heatsink, and heaven only knows how the motherboard is attached to the processor. But, damn, don't it looks good!

Seriously, I see all kinds of mechanical problems here with packaging, but since I have no idea what the design requirements were, I have to say that it does look impressive. See it here http://www.geocities.com.nyud.net:8090/oculus42/za lman.html

Now THAT is a fan.

It's long been known that Intel run a little hot, so Zalman have gone extreme with a cooling solution that finally does the biz.

Pumping an impressive 25 cubic metres of air per second Zalman are confident that the 'Big Boy Turbo Mega Fan 2' will be able to keep any Intel CPU, up to and including the Pentium 4 670 3.8GHz, running cool in even the warmest conditions.

Developed with the help of the British Aerospace wind tunnel engineers, the BBTMF can pump enough air to pop you double glazing out, so it comes with several precautionary notes, mainly involving the suction and loss of small pets whilst in the vicinity of your machine.

Drawing an impressive 1400Watts of power, Zalman include a full instruction booklet on how to daisy chain 5 300W PSU's together to power the fan, and you get 50 starter cartridges free to get it spinning in the first place. Of course, you'll need a serious case upgrade too, and we would recommend the CoolerMaster 821 Garage, which comes with a tasteful variety of electronic doors and leaves enough room for even the largest GFX cards in SLI and a Nissan Micra too.

Took me a bit to dig through the cache, but here's a pic: Zalman Big Cooler

So, I'll just stick with the useful stuff.

Although it doesn't look like it's gonna be a lot of help, here's the Coral Cache link.

Supposedly, the Mirrordot version will appear here at some point in the future, though it goes nowhere at time of posting.

Well, here's the Coral link.

HOWARD & NESTER!

HOWARD & NESTER!

I was there as part of a team from ICL (now part of Fujitsu) presenting some banking software to a group of about a dozen different banks. I was responsible for the technical end of the presentation (i.e., make sure the all the hardware / software / networking functioned properly) and to answer any technical questions the banks might have.

Most of the other Westerners I met as a result of this trip were there because of oil and other mineral interests. This was relatively soon after Kazakhstan had become independent and the Kazakhs were very interested in development and self-sufficiency.

I didn't see any sign of a McDonald's or other Western storefront while I was there but my time there was limited and there was a lot I didn't see. Almaty is quite a large city, somewhat reminiscent of Denver, so I didn't see most of it.

Almaty is right next to some large mountains and although our hotel was definitely in the city, there was a ski-lift only a few blocks away that would take you up the side of the mountains. It couldn't be more convenient for visitors to go skiing for the afternoon.

I would love the opportunity to go back there. The countries in that part of the world (the "stans") and their people are often portrayed negatively. I just wanted to let the people here at Slashdot, who probably haven't had a chance to visit KZ, know that it is very much worth doing.

There is a website at http://www.almadf.kz.nyud.net:8090/english/index.h tml that I found this morning which has a lot of photos showing how beautiful Almaty and its people are. I have no connection with that site and I have tried to avoid having it Slashdotted by using using Coral. Therefore I inserted ".nyud.net:8090" into the actual URL above.

I would like to know if there are there are any people from Kazakhstan reading Slashdot? I would have thought there should be. If you are from Kazakhstan and would like to make a friend in the U.S., please feel free to contact me at mailto:southcarolina1860-kazakhstan@yahoo.com

There are thousands of third-party applications available for Windows XP that have no direct Linux equivalents.

3 years ago a nice list of equivalents between Windows and Linux was done. Unfortunately it it no longer updated but the fact remains : there is almost one or more free software for each big need under Linux

Coral Cache

I think I'll lock the door so the IS department can't find me.

There's a coral cache of the static content, including screenshots, if you can't get through to my melted pile of servers.

Not to mention that google can lead to articles with much more information as a whole. Granted the writing style on that one is a tad dry with a little bit of jargon, but hey. Hmm... linked page also has some fairly big pictures, so I'd better coralize the link before it goes down.
