I understand why my mom used to tell me to "look it up"---it's a good habit to cultivate. But if someone's available and they won't mind, just asking is usually 10-100 times faster than looking it up.

If I didn't know much about what I was looking for (per this example), I could see myself spending a good hour trying to find an answer, vs. the few minutes it took to get one here.

That's what colleagues are for!

jsomers··on Ask YC: Good books to take on a week away?
Siddhartha, by Herman Hesse. Quick read, very elegantly written.

Nearly everyone that I know who has read it puts it at the top of their list.

jsomers··on 0.10 | 0.X What's in a version name?
this is the color of the bikeshed
jsomers··on New Type of Early Stage Investment Firm
Seems like a formula for (a) half-assery on the part of developers working on someone else's baby, and (b) incessant nagging from the "idea guys" who can neither communicate their feature requests nor understand their implications.

In short, a hip "seed" version of the company where Dilbert worked.

jsomers··on Interview with Donald Knuth
Knuth is the Warren Buffett of computers: phenomenally successful because he's a master of fundamentals, with an uncommon share of common sense. Also, a great writer (of books and software).
jsomers··on All of pg's hacker-news comments [using the archived post data]
Unless I'm mistaken, that page doesn't go back more than a day, which would mean it has less than a 1% of the data.

Could be there's a "more" button I'm not seeing, though.

jsomers··on All of pg's hacker-news comments [using the archived post data]
I enjoy pg's writing. in toto, these comments effectively comprise one giant essay, except that they're more focused. So why not?

In the same way, I don't regret reading Feynman's, Lewis Carroll's, or James Joyce's letters. Thoughtful people tend to write thoughtfully, whatever the context.

Incidentally, I probably would buy Knuth's keyboard.

jsomers··on Some Heroes
This was the only part of the essay that irked me. Bad writing in general has a low information density; the problem is not exclusive to fiction.

It doesn't help that information is embedded structurally in a novel, which makes it harder to tease out. But good fiction (say, Ulysses or Crime and Punishment or Nine Stories) is as rich as any essay or monograph.

It's also not clear that density, in the strict sense, is what I'm after when I read. If so I'd be buried in technical papers, when what I really want is something to tickle my brain; to that end, I wouldn't want to lose any one of arXiv, the Engineering library, or the literature section at Borders.

jsomers··on Disagreeing with Paul Graham
"Simple bacterial reproduction does just fine."

Sure, until one bacterium in your neighborhood starts working out---then you better hit the gym, too. Onwards and upwards.

jsomers··on More data usually beats better algorithms
"Team B used a very simple algorithm, but they added in additional data beyond the Netflix set: information about movie genres from the Internet Movie Database (IMDB)."

I had no idea imdb had so much genre data. E.g., a "keywords" page for every movie [http://www.imdb.com/title/tt0062622/keywords] and, for every keyword, maps of (a) related keywords and (b) movies that mention it [c.f., http://www.imdb.com/keyword/metaphysical/].

Very cool.

jsomers··on My dad recommended this course - should I bother?
It probably depends on the professor: is this Gibbon guy a good teacher? Try to find out if he's taught the course before and how it went.

It's the difference between just learning cute terminology (bad professor) and initiating a real interest/solving hard problems in the subject (good professor).

jsomers··on Are MacBooks Just Trendy?
I just think it's unfair to say something is "masturbatory" when you're using human life as your measuring stick.

You can't expect everyone to devote themselves to your idea of worthwhile work, and you shouldn't begrudge their momentary diversions.

I don't begrudge you for closely following an internet comment thread when there are people suffering.

jsomers··on Are MacBooks Just Trendy?
I don't like this argument. For one you're on "Hacker News," a forum for hackers who hack with (mostly) computers.

Keep in mind also that a lot of what we regard as essential today, say, the foundations of computer science (bits, formal language theory, algorithms) were once the trivial ejaculations of bearded professors in some ivory tower.

We need people dicking around in masturbatory enclaves solving puzzles, just as we need agitators and activists. I think it's unfair to say one group works at the expense of the other.

jsomers··on Craig Venter: Joining 3.5 Billion Years of Microbial Invention [mp3]
Save time and read a text summary: http://blog.longnow.org/2008/02/26/craig-venter-joining-35-b...

> Venter proposed that our current energy and climate situation requires truly disruptive technology. One project he’s working on would use altered microbes to metabolize coal in the ground and generate methane, for a tenfold increase in carbon efficiency. Another project proposes a “4th generation biofuel,” where engineered algae directly convert CO2 into hydrogen in bioreactors.

jsomers··on The secret of my success
I think there's a good reason negativity signals intelligence. Scholarship is about _critical_ thinking, challenging assertions, falsifying hypotheses, etc. If you agree with something it could therefore appear like you didn't do enough research to find some flaw with it.

In any case, contrarianism is rampant where I am (undergrad at umich), and it gets annoying when the default reaction---often without basis---is disagreement.

jsomers··on The secret to winning at rock, paper, scissors
I just look at my watch and take the seconds mod 3. 0:rock, 1:paper, 2:scissors. Pretty sure random play (insofar as this method is random) is best.
jsomers··on Low-Cost Multi-touch Whiteboard using the Wii Remote
I'm not much of a hardware hacker but this looks like a pretty small DIY project. A tighter, nicer package might be nice but I think the point is that the ``commercialized" version (cf. Microsoft Surface) is really expensive.
jsomers··on Project Euler - Fun Math and Programming Problems
The trick is you need to solve them in less than a minute (of computer time, of course). Believe me, it gets tricky.

52% complete, Rank 369 out of 7362.

jsomers··on Ask YC: favorite books
Godel, Escher, Bach (An Eternal Golden Braid) by Douglas Hofstadter. Also, The Mind's I (more philosophical) edited by the same guy.
jsomers··on Google releases 'My Location' for cellphones (w/ google maps)
It gave my location to within a few blocks. In a small town without a car, though, "a few blocks" is significant. Not obviously useful to me, yet.
jsomers··on How to Develop a Mindset for Math
Yes, math -- like every other discipline that can take itself seriously -- is about models and relationships. But given these models, we ought not necessarily "apply them to real-world objects." Rigorous math is powerful precisely because it is abstract.

One of this guy's prized "deep insights" is that negative numbers refer to deficits of cows. Granted, that's a slick (if not wholly obvious) way to represent an intuitively awkward concept, but it engenders a false confidence. Negative numbers don't exist to represent bookkeeping deficits. They are there because some formal mathematical argument grounded in pure logic said they had to be there. The fact that we use negatives to refer to cows reveals more about primitive functions of the human brain (distinguishing among objects, counting) than it does the deep algebraic structure of the numbers themselves.

I admire attempts to ground difficult abstractions in physical reality as much as the next guy, but we shouldn't confuse these simplistic observations with mathematical insight.

jsomers··on Google Maps now has Terrain view
At least in my area (Ann Arbor), the resolution is too low to see much. As a cyclist/runner, for instance, one might be curious about steep inclines around town. No such luck here.
