Hey, does anybody have that documents from Spiegel? I clicked the link but it says not found. Probably it is from 5 years ago so they take down the pdf documents.

linhchi | 7 years ago | on: China scours social media, erases thousands of accounts

I think that when you suppress freedom systematically, stuff find other ways to come out, and it comes out ugly. (Like when you suppress healthy sexuality).

That explains the weird stuff floating around Vietnam social media (which is a smaller scale version).

linhchi | 9 years ago | on: Ask HN: What handheld device you are using?

If you get a small phone, what do you need keyboard for? Coding or writing drafts? I think the small phone you get will replace iphone4s but don't you feel the need to get a middle solution between small smart phones and a full functioning laptop?

linhchi | 9 years ago | on: Ask HN: What handheld device you are using?

I use my old smart phone for the things you list also. But i'd like to be more productive. Probably an ultra light laptop or netbook. I'd like to be able to code, read books, scribble ideas.. It should be in the middle between a laptop and a smart phone. It's just that there are so many brands today.

linhchi | 9 years ago | on: To write better code, read Virginia Woolf

Because stories like this sell to even the lowest audience target: the lazy but dream big ones.

No matter how dumbed-down the tone, for me behind it always lies a figured out person doing smt that is definitely cool from the start.

More than just selling to the lazy ones, it protects itself from being criticised by the competent ones. (You end your concern w an agreeing sentence: the point is valid). (It can do this because it's written by a cool guy sharing cool stuff).

What i take from a story like this is that it's not abt CS, not abt woolf. It's basically: "how to become a perfect painter? Become a perfect person, then paint naturally"

linhchi | 9 years ago | on: How the Gut Affects Mood

I clearly have the mood affecting gut. If i have a sinking feeling in my chest (a devastated one), i immediately have a painful reaction in the bowel (or the gut).

linhchi | 9 years ago | on: Does power really corrupt?

But people with more power are the ones that have to make the hard choices. And hard choices are hard, true by definition.

If one never has to burden any thing on one's shoulder, probably that one is the burden of someone else. It's like this: we civil people can't stand killing and shooting, that's why we outsource it to the government and praise the army for their service.

Is it hypocritical? I don't know anymore.

linhchi | 9 years ago | on: Programming by poking: why MIT stopped teaching SICP

I'm not techie, so i'd like to ask if my interpretation is ok. The switch from scheme to python is in the tidal change of conceptual thinking? Previously, giants & pioneers approach AI systematically, w consistent logic and clean structure (like maths language).

However, for now, the narrative shifts to "poking around, hoping to poke the right thing"?

I use Racket & its thinking for research. I think that structured thinking is still intellectually important. So it'd still survive, as there'd still be people sticking w it.

linhchi | 9 years ago | on: Economist Removed from Plane for Algebra

:) oh come on, every field has the problem of faker and pretentious practitioner. Because studying everything takes serious effort, hence if you're lazy, you get empathy, but if you work hard while people around you don't, you get the hypothesis that you're elitist and fancy. And they have ground for that hypothesis, because It's true that faking wisdom gets some glamour too.

linhchi | 9 years ago | on: Economist Removed from Plane for Algebra

It's witch-hunting, isn't it. Amist the hype of fear, you'd better not showing your knowledge on anything, (for the witch, it's knowledge on herb and natural healing).

linhchi | 10 years ago | on: Correlation implies Causation (2009)

Correlation has a formula, it detects the linear relation between two variables. So the quadratic relation is actually having zero correlation.

Second, in academic research, we mean 'correlation doesnt imply direct causation'. Because we're talking science (what's significant) not astrology (as above, so below).

For example, the octopus predicts the results of football match correctly most of the time. But as a scientific person, would you say that there is any conceivable causation?

The important word is conceivable.
