jlefo7p6··on Pedagogy of the Oppressor
Tell us how you really feel: "...His declaration in Pedagogy of the Oppressed that there was 'no such thing as a neutral education' became a mantra for leftist professors, who could use it to justify proselytizing for America-hating causes in the college classroom..."

I know hackernews doesn't obsess about being "fair and unbiased" as much some sites, but I'm unwilling to consider an argument couched in such ridiculous terms.

jlefo7p6··on Brainstorm HN: Outlandish Startup Ideas Pool
I totally bought a wind-up OLPC laptop last Christmas, with one extra feature: vaporware crank.
jlefo7p6··on Why can't we concentrate?
Limiting yourself to works with a narrative hook in the first few sentences is a mistake.
jlefo7p6··on Tell HN: Wolfram Alpha preview goes live
I can appreciate Empiricism as much as the next guy, but Google Search, Cuil, and Alpha seem comparable.

edit: the dreaded homonym! I mean they can be meaningfully compared to each other, not that they are the equivalent.

jlefo7p6··on Ask HN: How to detect if app is pirated?
This might help: http://thwart-ipa-cracks.blogspot.com/2008/11/detection.html
jlefo7p6··on Diversification = Mediocrity.
We've already heard today that focusing too much is bad (http://news.ycombinator.com/item?id=599977).

All we need is an article warning against a balance, and we'll have the whole set!

jlefo7p6··on Tell HN: Wolfram Alpha preview goes live
I guess Alpha could come with tech support to gently rearrange your questions, but it seems like cheating ;)
jlefo7p6··on Ask HN: How to detect if app is pirated?
You'd have the make the subscription cheaper to offset the app's cost, so you'd still be losing money on piracy. Plus, making the end user pay twice sounds annoying.

It sounds like Apple set it up this way to make sure they are getting a piece of all the money coming through the iPhone. I won't begrudge them that, but I feel for the developers.

jlefo7p6··on Why silent [browser] updates boost security
The title is a little off: security updates boost security, and silent updates boost adoption of updates.

The recent stink with Adblock Plus and NoScript using my browser in their personal snowball fight makes me leery of auto-updates. Making the normative choice the default setting has an okay track record, but I'd like as many as eyes as possible helping me keep developers in line with my needs.

jlefo7p6··on Being too successful is one of life's biggest risks (2004)
That book looks hugely interesting--thanks for the recommendation!

We've been using biological metaphors in this discussion, but I'm not sure we can extend them this far.

jlefo7p6··on Ask HN: How to detect if app is pirated?
Hand the software out for free and charge for user accounts on the server.

This turns the problem into one of "How do I prevent account piracy?", which is hopefully not dependent on characteristics of the iPhone.

edit: I'm not sure what sort of kickback Apple would like in this case. Be sure to check that out first.

jlefo7p6··on KIVA Robots Continue to Conquer Warehouses
The photo of the wide corridor of KIVA's bustling past each other struck me as beautiful. Maybe I should get some sleep ;)

Like the Roomba, these guys found a way to use tech that we already have to do something magical.

jlefo7p6··on Being too successful is one of life's biggest risks (2004)
The amazing thing is that there is a lot of repetition even at 10 paragraphs. Some of the other comments here sum it up in twitter-sized chunks.

The missing piece is how to identify over-specialization, and it's missing because it can't be usefully generalized.

jlefo7p6··on Unsolved problems in physics
I think you were referring to the n-body problem (http://en.wikipedia.org/wiki/N-body_problem). If so, I suggest not neglecting gravity.

Without gravity (and either assuming these guys don't run into each other or can somehow pass through each other), the position of each body is independent, and can be found through the following equation:

Position = Initial + (Velocity * Time)

Blah blah vector components blah blah, but you get my point.

jlefo7p6··on Exploiting spammers to make computers smarter
It's a lot harder to take this stance if your site is impacted by the arms race, but it is cheery news for the technologist inside us all.

One caveat is that this sort of development seems more likely to remain in the darknet.

jlefo7p6··on The 4 Hour Workday
"If you view work as something that starts at 9 and ends at 5, you won’t be able to finish everything by noon."

"If You Work at Home, Never Work 9-5"

But it's only a fencepost error.

jlefo7p6··on News Corp Sees Big Drop in MySpace Ad Revenue
blink tags... check.

embedded audio... check.

obligatory webrings... check.

homemade pokedex... missing!

It fails my unit tests for Geocities-ness, but I think you were referring to the recent collapse. I'll second that motion.

jlefo7p6··on Is the use of computers harmful to introductory CS pedagogy?
I enjoy programming, and I learn the theory behind it to make my programming better. Since motivation is an important part of introductory classes, I'm okay with the current order.

Mathematics, on the other hand, doesn't start getting good until after calculus. Mixing the order up there is something I could get behind.

jlefo7p6··on The Problem with the Stock Market
I'm not sure how investing is taxed right now. On the assumption that the author is calling for an existing tax to be taken away from a certain kind of investment:

Under the current tax structure, the author believes that investors are encouraged to engage is overly risky behavior. It is not obvious that reducing taxes on a subset of financial instruments will make the rest of the instruments less appealing. The flexibility of the taxed instruments is not necessarily made up for by an increase in the rewards of the untaxed instruments. Massively increasing taxes on the instruments you dislike seems like a more straightforward incentive system.

(I'm not convinced that choice of instrument divides investors into "good" and "bad" categories, but the author's proposed solution seemed like an easier target.)
