BBC Nonsense

they'll just randomly report that the 2nd law of thermodynamics is wrong with no apparent case.

FYI microscopic laws being 'time reversible' means that a movie of the events played backwards does not violate the microscopic laws. (the article uses the term but doesn't say what it means)

neat cs trick

found here

u might not follow that explanation though, so i'll write it simpler:

computer data is often stored in arrays (basically a bunch of stuff in a row). arrays have a fixed size in memory. sometimes they get full. the basic solution is you make a new, larger array, and copy all the old data into it.

in comp sci classes they generally teach (or maybe only used to, dunno) that you should make the new array double the size of the old. you want to try not to waste too much memory by making it bigger than needed, but also increase the size enough not to have to do this very often, because copying over all the data is expensive.

anyhow, if your array takes up 1 unit of memory, and you double, the new one takes 2 units of memory, with a gap of 1 empty unit behind you. next doubling, your array takes 4 with a gap of 3. then takes 8 with a gap of 7.

see the problem? the array never fits into the gap.

if you increase the array by a factor of 1.5 instead, it will fit into the gap.

actually works pretty fast. 1.5 with 1 gap. then 2.5 gap and array is 1.5*1.5=2.25 ... already fits.

anyway, it's a neat improvement.

my logical conclusions

IMAO who is usually right and often very funny, writes:

As Opinion Journal pointed out, this poll shows that the average Republican knows more about the Democrat presidential nominees than the average Democrat, even though there ain't a way in God's name we'd ever vote for them. And I remember seeing some article arguing that we're the party of the dumb. It's a fact that, if someone closely follows politics, odds are he or she is a Republican. Draw your own logical conclusion from that.

well, sorry, but the implied argument is not valid.

the implied argument is that paying attention to politics causes people to be Republican, and that we know this because the poll correlated paying attention to politics with being a Republican (and i expect other polls have too).

BTW I happen to think the conclusion is true: I do think paying attention causes people to become Republican. I just don't think we can say this is true *because* of the poll.

the problem is CORRELATION DOES NOT IMPLY CAUSATION (which i've never ever once had someone even try to disagree with). see, from the poll all we get is correlation. the causation could be something else entirely besides the one IMAO picked. like maybe something about being a Republican in the first place makes you more inclined to watch the news. or maybe Republicans tend to go to Church more, and Churches tend to promote political thinking (erm, maybe not that one). or maybe religious people care more. or it could be any cause, for all the poll tells us.

UPDATE:

A) Frank J visited *my blog* (see comments). i belive that makes my blog famous by association, so you should visit more often now, and make your friends visit, and stuff.

B) Frank did not intend the argument I said he implied. My apologies for the error. I think he could have been clearer, but he's right that he didn't actually say anything wrong, I just falsely assumed he meant something bad.

C) I'll leave this up because other, lesser people than Frank J might argue that way on purpose (maybe a liberal) so the correction would be important then.

curi42 (2:42:51 PM): this senator wants ammendment to give $47mil to fight autism. he starts giving reasons fighting autism is important. ur josh listening. imagine agreeing was politically ok (happens to not be ok to have more ammendments on bill, but forget taht)
curi42 (2:43:22 PM): ok fighting autism is good. but should the money go to that, or to something else that's also good? how could josh tell? HE COULDN"T!
curi42 (2:44:03 PM): this is why government taking everyone's money into a big pool then trying to divy it up for everything is a bad idea. he doesn't have the information for where it should go, and there's no easy or good way to get it in that system.
curi42 (2:45:16 PM): whereas if the ppl kept their money this problem wouldn't exist. they'd do stuff they knew about, comparing only the things they know about. and overall it'd avg out just fine. (or sometimes there'd be common misconceptions and it wouldn't; but messing up common misconceptions beats messing up all of josh's)


curi42 (2:48:46 PM): it just struck me when the guy was trying to sell josh on the idea that ppl argue "u should spend money on my cause b/c my cause is good" whihc *completely misses the point*
curi42 (2:48:53 PM): there are lots of good things.
AnonymousPerson (2:51:23 PM): Like with the risk thingy, before i let Josh decide a thing like how much money autism research should get, I want him to tell me, within two orders of magnitude, how many ball bearings are needed this year.


curi42 (2:57:21 PM): turns out he was asking b/c he had an autistic grandson
curi42 (2:57:31 PM): now *that's* a good way to decide where to spend money
curi42 (2:58:29 PM): there are things where you want a unified policy. but choosing btwn autism research and cancer research isn't one. everyone should go their own way on those, so we'll get some of each.
curi42 (3:02:39 PM): nooooooooooooooooooooooooo wtf
curi42 (3:03:24 PM): ok the guy is doing fillibuster and gonna drop soon but screwing them up. but they realise he can safely yield floor for a question and still get it back.
curi42 (3:03:45 PM): so i figure they will ask "is it true you're only doing this b/c u have a grandson with autism?" or something to embarass him to shut him up
curi42 (3:04:27 PM): instead the question is 22 parts (and from a grandfather) so he can rest, then other ppl ask questions. they decided b/c he was doing it for grandson that they should help him.
curi42 (3:04:37 PM): do leftists really think that's being humane, and i'm an evil bastard?
curi42 (3:04:43 PM): cause if so, they should be shot :)
