jsomers··on A story of the rise and fall of a serious attempt at a proof that P!=NP
That seems true in general, but it's still dangerous to declare that you're working on a famous problem (P!=NP, 3n+1, Riemann); it's something you keep to yourself until you've made serious progress.
jsomers··on Pressure-sensitive keyboard
Maybe it could be used to reduce typos--when I mistakenly hit "K" on my way to "P", I bet I do it with less force (at least most of the time).
jsomers··on Dude’s Night, Cooking 101 for Hackers
The crab cakes look good.
jsomers··on The TED commandments - rules every speaker needs to know
I'm judging by the dearth of comments here that these rules are considered excellent (hence the upvotes) but obvious (so no discussion). Which makes me wonder how valuable they are, especially to the kind of people invited to speak at TED...
jsomers··on Free Online Graph Paper / Grid Paper PDFs
Neat idea, especially if you only need one or two sheets of the stuff. Any more and you're probably better off heading to an office supply store (if only to save on costly printer ink).
jsomers··on Eric Drexler: How to Understand Everything (and Why)
In a follow-on post, I plan to say more about the method of study that I’ve found effective. I got rolling with the new journal sections of the MIT libraries, but today, the internet should serve even better.

That may turn out to be the more valuable post -- I hope to see it on the front page here whenever it's ready.

jsomers··on Stephen Wolfram’s Introduction to Wolfram Alpha (screencast)
If nothing else this is a gorgeous application -- it looks great. And in fact it looks like something I might use as often as Wikipedia (though not as often as Google).

I can't wait to play around with it; some of these examples (nutritional labels, the actuarial stuff, ISS location, etc.) are just dead cool.

jsomers··on How David Beats Goliath
Like Gladwell points out, you have to be extremely well-conditioned to press for a whole game. It takes a lot out of you. So it could be counter-productive if your team isn't in excellent shape, because a poorly executed press (say, if your team is tired) makes it easy for the offense to just blow by you and hit layups.

That said, a team of good ball-handlers can beat a strong press if they stay calm and pass well. Patience and poise.

(Which is probably why the press is so effective in younger leagues: players at that age get frantic under pressure and just don't have the dexterity/skill to keep the ball under control)

jsomers··on College Prestige "Lies"
Cool. I'd be curious to know some of what you picked up in grad school. Care to elaborate?
jsomers··on Growing Sentences with David Foster Wallace
Hmm, DFW's sentences are occasionally indulgent, but they don't sound like this. Here's a sample chosen (somewhat) haphazardly:

If we want to know what American normality is -- what Americans want to regard as normal -- we can trust television. For television's whole raison is reflecting what people want to see. It's a mirror. Not the Stendhalian mirror reflecting the blue sky and mud puddle. More like the overlit bathroom mirror before which the teenager monitors his biceps and determines his better profile. This kind of window on nervous American self-perception is just invaluable, fiction-wise.

His style begs to be parodied but this is a facile attempt, in my opinion.

jsomers··on How I almost killed Facebook
I don't think he is being entirely serious in this post, which is sprinkled with self-deprecation masquerading as egotism.
jsomers··on The next generation of mirrors
Pun intended?
jsomers··on Ask YC: Can you control the lizard-spit function?
Thanks! That's exactly what I was looking for.
jsomers··on The Canadian Solution
Oh boy... regardless of the strength of the argument here, I'm going to be sending this to virtually everyone I know.

- a Canadian in America

jsomers··on Industrial Society and Its Future (Unabomber Manifesto)
Although it's written by a murderer, there is a lot of good thought and even humor in this piece.
jsomers··on Bill Gates' Q&A with Chris Anderson: Video unveiled
This is great. Gates seems a lot sharper (and funnier) when speaking extemporaneously.
jsomers··on The Great College Hoax
I'm reminded of (Good) Will Hunting's zing to some jerk in a bar, right after calling him out (in a pretty spectacular way) for plagiarizing:

"See, the sad thing about a guy like you is in fifty years you're going start doing some thinking of your own, and you're gonna come up with the fact that there are two certainties in life. One, don't do that. And two, you dropped a hundred and fifty grand on a fucking education you coulda got a dollar fifty in late charges at the public library."

"Yeah, but I will have a degree," he says in return.

It's an open question whether the markets in general (i.e. not just startups, tech, etc.) will get over the apparent value baked into a college degree / GPA, and start worrying about what kids can do, what they know, and how they think.

jsomers··on Clay Shirky: A Group Is Its Own Worst Enemy - Social Software Design
I recall PG saying something a while back about a "rollback" feature that would give you the option to only display those comments and submissions created by users above a certain account-age/karma threshold. So in effect you could turn a knob and the site would roll back to, say, the user base from 300 days ago.

I thought it sounded like a pretty elegant (if potentially divisive) solution, maybe worth serious consideration.

jsomers··on Code Like a Pythonista: Idiomatic Python
I had no idea that "_" stores the last printed expression in the interactive interpreter. That little tip, and the wonderful visual description of Python's "names," were worth more than enough to cover the cost of reading the whole article.
jsomers··on Kurt Gödel: A Contradiction in the U.S. Constitution‎
Presumably it has something to do with an amendment that prevents future amendments, or gives that right to a single person (dictator).
jsomers··on A Defense of Philosophy (against Paul Graham)
PG's "most" includes more than I'm comfortable with, which is why I wrote the essay -- to defend those parts of the subject that I thought were unfairly called a waste of time.

My "most," in other words, includes less than his.

jsomers··on Why thinking in the shower may be an ideal model for "creative pause"
Sure did, though I'm not sure if that's the case anymore -- I have this great chair now...
jsomers··on Feedback on Startup: Videoly - simple video email site
Because that way you'd lose the picture of the babe...

Agreed, though: an example of your service in action is the first thing I'd want to see (after reading the nice, simple explanation of what it does).

jsomers··on Knuth is no longer mailing out checks for $2.56
If you attach dates on a page like this, you risk looking flaky whenever there's a big gap between posts. Leaving his entries dateless might mitigate the pressure to update regularly. That's just a guess, though.
jsomers··on Physics Invader = Space Invader + Physics
> This is typical innovation... mixing two things together to make a third thing.

I'd argue that every innovation involves mixing two (or more) things to produce a third. So calling it "typical" is a gross understatement.

If you don't find the game compelling, it's not because the combinatorial (a + b = c) form of innovation is somehow uninteresting, but because the elements are.

I agree that (space invaders) + physics = (moderately more engaging version of space invaders).

jsomers··on In Praise of Scripting: Real Programming Pragmatism
Good essay.

I liken the difference between Python and Java to internships at small and large companies, respectively. In the small company, you can do meaningful work in any department—you can be the cook, accountant, and network engineer in the same day, just as you can parse XML, send automated e-mails, and invert large matrices in Python with plug-and-play modules. At a small company everything's transparent, and on a scale you can understand; there's no organization for organization's sake, no vapid meetings or processes, just problems that need to be solved and the tools you need to solve them.

It is only when the small company grows, when the founders can't interview every new employee and the clients aren't recognizable by name, when managers and engineers are disjoint groups, that one needs all the stuff they teach you at business school. To round out the conceit: the Java curriculum is that stuff. And to a kid just learning to program, it's cruft.

jsomers··on When is one thing equal to some other thing? [pdf]
This is very nicely written. Just a warning, though, that it's not quite light reading.

Pop quiz: what's a morphism of functors?

jsomers··on Guessing the Teacher's Password
yeah, although you'd have a lot more work to do. Not only are there multiple posts a day but some of Elizer's have dependency trees reaching months back!
jsomers··on [dead]
This is how one spoils a playful idea, and how imaginations fade.
jsomers··on An Interview with Douglas R. Hofstadter
I feel a special kind of levity whenever I read something Hofstadter's written, or when I listen to Feynman speak.

Is there anyone else who does that?
