Development of stock trading systems, which are also trying to rank things based on historical data, have this persistent problem there's been waaay more research into than chess rankings. If you train them on a bunch of historical data, you will discover the best system is invariably one that essentially does a giant curve fitting job on that exact data. One thing trading system developers do to address this are use techniques like walk forward testing, where the system gets trained on one set of data but is only evaluated on a second set.
Luckily, this chess rating competition is using that sort of technique: "Competitors train their rating systems using a training dataset of over 65,000 recent results for 8,631 top players. Participants then use their method to predict the outcome of a further 7,809 games." In fact, the current leaderboard reflects results on only 1/10 of the training set. So long as real ranking is ultimately based on the unseen data set, not the training one, there's little risk of them fitting the noise in the training set and still winning.
FreeBSD 8.1 is now only a year behind OpenSolaris in terms of its ZFS support; it's compatible with pools created with OpenSolaris 2009.06. If you assume that freely available innovation from Oracle's side is going to stagnate, it shouldn't take long until they've caught up with the latest of the open-source ZFS releases. At that point it will be FreeBSD vs. paid Oracle Solaris as the presumed only way to get advancements. Since I don't actually care about the non-free crap that Oracle peddles, I expect a near future point where the FreeBSD version could be the only interesting ZFS release to me.
There are a couple of different models of car available as part of the Mary Kay Career Car program, not just the Cadillacs. The cars aren't really bonuses, you can get them in lieu of cash for building a team with enough sales; intro. If your goal is to recruit more people to do even more sales, it's understandable how driving around the car could be worth more in new business than it costs.
I hear Chatroulette is paying good money for minors who willing to help them clean their site up. The job requirements are that the kids are easily offended and willing to press charges.
Ottumwa is the founding location of Twin Galaxies, and from 1982 to 1984 it really was the video game capital of the US at least. Nowadays, I find it much more convenient to visit Funspot when I'm looking for that sort of thing though, rather than go to the middle of Iowa. (All of Iowa feels like the middle)
Unless the other stuff you were talking about is filmed at the studio location in the middle of the goatse guy's anus, the one just left of the Starbuck's.
It's data for model railroading magazine, so not only are they used to rails, they already have protocols to serialize access to shared resources and prevent collisions.
None of the drives listed in this round-up are suitable for PostgreSQL use, or for most other reliable database setups too. In order to use a drive's write cache in PostgreSQL for fast handling of the fsync system call, the main bottleneck on things like the database write-ahead log, it must be non-volatile: not lost if there's a system crash or power failure. None of these drives offer that, and in fact some of them (like Intel's) actually lie about the disk writes in a way that will result in database corruption after a crash. See the archives of the pgsql-performance mailing list for a lot more details.
The next generation of Sandforce based drives, which should appear relatively soon as an OCV Vertex product, will include a write cache backed with an ultracap design that provides battery backup in case of a failure. Right now you can't get that in any of these cheap consumer drives, only in much more expensive "enterprise SSD" models like those from FusionIO. Once one of these ultracap designs ships, I expect a significant expansion of SSD for PostgreSQL use.
It has been theorized that the accidents are more prevalent in Toyota vehicles because their brand positioning makes them likely to be driven by older people more prone to accidents, in addition to the selection bias that comes from this being a high profile issue.
All physical hardware I own running Windows still has 2000. I will only install XP into a VM, where the things that trigger the reactivation mechanism don't happen. Same virtual motherboard, MAC address, RAM size; only thing that changes if I move it to another PC is that the VM sees a new CPU, which by itself isn't enough to cause a problem. Also, easy to make a snapshot of a working system that is activated, so I can roll back to it if my system does get deactivated somehow. (Note that I've paid for at least 3 XP licenses on new hardware, so it's not like I don't have the licenses available to put one on every real system).
When activation was added to Windows, I said at that point I would never deploy a critical computer system using Windows again. I don't buy software that can decide to turn itself off and take my computer down with it, leaving me at the mercy of some company's whims as to whether I can start it again or not.
The video for 'Fish heads" actually predated MTV by several years. Us old folks saw it for the first time on Saturday Night Live, where it premiered in December of 1980.
I spent an hour in a plane that was stuck on the runway today, not an uncommon situation when traveling. The ban on electronic devices during takeoff was active the whole time; I read a magazine.
Yeah, that will work great given how much governments respects privacy. Presumably we'll get a "add this person to the terrorist watchlist" button right on each US profile?
The value of a social network is proportional to the number of members it has. Facebook started in 2004 aimed at students, grew for a while, and in 2006 opened membership to everyone. It was two years after that (and two years ago) when Facebook exceeded Myspace, and it's just been pulling ahead since. It's now blown away any previous social network scale now. If you started tomorrow with a compelling site people might use instead of Facebook--the same way that Facebook was a compelling improvement over Myspace--best case it would be two years before you'd even have a shot of being popular enough to be considered a viable alternative here. The unfortunate reality here is that making this sort of site available to most people for free costs somebody money, and that will never go on forever without somebody trying to make a buck. Social networks trying to expand are practically forced into it just to pay for their overhead as popularity increases.
As for the privacy issues, I never told Facebook anything private in the first place; anybody who did is a fool. I didn't care that they were throwing ads in my face that were obviously targeted to interests I listed in my profile to make ad dollars; expected that, all part of getting the site for free, and things like my music/movie likes are quite public information already. But last week when I visited cnn.com to read a news story, and it magically showed me what news stories my Facebook friends had been looking at (and presumably exposing what I was doing to them), that was the point where I felt myself that Facebook had gone rogue. Time to use UnFuck Facebook and crank up the rest of my hostile site defenses now. Facebook I'm now treating like a link that might lead to p0rn: I might still go there if because it's fun sometimes to look at, but I won't be adding to their ad income and I expect the site to be hostile. And I'll go out of my way to avoid all the sites they're selling my info to as well.
I'd like to have seen them run MySQL, PostgreSQL or SQLite through the same tests so we could see how these NoSQL solutions compared.
That wouldn't have made any sense given the replication scheme used: "N=3 (replicas for each entry), R=2 (nodes to wait for on each read), W=2 (nodes to block for on each write)". It's hard to translate that into the sort of replication features available in the other databases you mentioned.
Also, these tests focused on individual put/get operations, where a standard database is going to get creamed no matter what. You'd need to include something that had a higher-level query component to it than that to even approach fair. To use a social networking example, the benchmark ran tested how long it might take for one of these databases to look up a piece of information about one of your friends. To get something where a comparison against a regular database would be more fair, you'd want queries like "get the list of all my friends" instead.

No, thank you very little.
Heading to the store to pick up a Baby Ruth.
Oh, in that case, probably "I'm an erudite GNU/prick".
Call me when it can accurately decide when I meant when typing commands using vi or emacs.

I've watched men pay ugly strippers to put their clothes back on.

The air travel system didn't sell me a lottery ticket...
Then why is it that I feel like I've hit the lottery on the rare occasion when I actually make a connecting flight?
That's right, I pay extra to get a genuine, Sony branded rootkit instead of the cheap ones that Dell ships.

And "dragnet" already has an awesome theme song.
A man's anus pales in comparison.

Let's say you stuck 2002's Michael Vick (you know, when he was an NFL cheat code) into a Midget league.
Now I know what feature I want to see added to EA's Madden NFL 2011.
