Anywho, they don't look as bad as I was thinking, and the fact that it supports onboard video with a dual-core CPU raises interesting questions about the engine. It just means that the graphic engine goes from very low graphics to possibly high graphics.
Current versions of ZFS have the feature where the ZIL (ZFS Intent Log) can be separated out of a pool's data devices and onto it's own disk. Generally, you'd want that disk to be as fast as possible, and these SSDs will be the winner in that respect. Can't wait! As far as I know, contiguous writing of large chunks of data is slower for flash drives than plain HDD's. I'm guessing the ZIL is some kind of transactional journal log, where all disk writes go before they hit the main storage section of the filesystem? I don't think you'd get much of a speed bonus. SSDs are only really good for random access reads like OLTP databases.
If you find you have to create thousands of columns response_0001, response_0002,... response_4096, then you should probably realize that there's something wrong with your schema. It's just basic database normalization. (Though I suppose you might have a reason for doing it this way. But it sounds incredibly horrible.)
The introductory physics classes at Carnegie Mellon use VPython to run some simulations. It's pretty simple to use and intuitive. The textbook makes use of it too.
What's wrong with/etc/init.d? It's just a matter of preference or old vs. new.
I'm not quite sure how it works in Ubuntu, but in Gentoo, there's a tool that manages the services that run with each runlevel, and I prefer using that instead of manually moving around shell scripts.
I wish they had closed-captioning though. No offense, but the accents combined with poor Youtube/recording audio quality make it really hard to understand what they're saying.
It's a shame, because the material covered is pretty good and broad.
That aside, if anyone has an old copy, or knows of an image online, I would very much appreciate the correlation of ecidence. If you had read the FA, you would have seen this exact same point made there;)
Ah crap, should have previewed. My second bullet point had my markers removed. It should have read:
Actual smart tab completion. SELECT * FROM in psql will show a list of tables/views ONLY. In mysql, it'll show all data structures, such as every single COLUMN for all tables. I can also do: SELECT * FROM table WHERE and get the list of columns for that table ONLY. This even works when you do joins. Tell me if you're able to do that in mysql, because that would be really convenient.
I hate the mysql commandline. Here are the things I can't do in it (or I've been too lazy to try to figure out how):
Use ctrl-c to reset the prompt (clears the current line). Ctrl-d will then actually quit the program. (not terribly important, but still convenient)

psql opens up less to show big data
... and a couple of things I can't think of at the moment.
Like I said, these features might be available for mysql; I just haven't been able to figure out how (and if so, it is much less apparent than psql)
Well, Postgres has support for Perl or Python or Ruby or Java, or in their pgSQL language for user-defined functions.. that's a huge plus compared to writing in C for simple things.

How's that for ugly?;)

Just RTFA!
Wasn't there just a slashdot story about this? "How To Teach a Healthy Dose of Skepticism?"

Yes, except it takes more energy to separate the hydrogen atoms than you'd get from burning them.
The guy is absolutely right. Anyone designing a database schema should know this.

How does knowing facts about the Beatles (2/10 questions) have anything to do with IQ?

Prepositions are important :)
I think it really depends on the college. I can potentially get 100 units (out of a 360 needed to graduate) from my AP credits at Carnegie Mellon:

A lot of people take these courses at my school too. I'm happy not to have to pay the huge tuition fee to take some of these classes..
Are you absolutely sure you're not getting any false positives there?
Embrace, extend...

Haha, funniest thing I've read today.
i'd mod down if i had any points
And only SIX PERCENT of these 1000 smart teens liked heavy metal? That isn't much at all...
