quantisan··on Tokyo medical school altered test scores to keep women out
"Women often quit after graduating and becoming a doctor, when they get married and have a child," one source told the Yomiuri, in justifying the blanket alterations of admission scores.

"There is a consensus inside the university that male doctors support the university hospital," which often requires emergency duties and long shifts, the source told the daily.

quantisan··on Mr. Rogers was my actual neighbor
tl;dr the author had a one-time encounter with Mr. Rogers when the author was soliciting donations for his little league. Mr. Rogers was as empathetic as he was portrayed on his shows. That erased any previous doubt that the author had regarding Mr. Rogers' authenticity.
quantisan··on The Machine That Builds Itself: The Strengths of the Lisp Languages (2016)
Because OP is blaming the tool and not the programmer. You can have zero unit test or docstring in any language, not just Lisp.
quantisan··on The Machine That Builds Itself: The Strengths of the Lisp Languages (2016)
Languages don't create unmaintainable code, people do. I don't get why there's such hate against Lisp. (Granted, as others have noted, the author of this paper obviously drank from the Lisp kool-aid fountain)
quantisan··on Asian Americans are the least likely in the US to be promoted to management
The change in headline from the original article is misleading. The article gives data that Asian American are under-represented in management across a few professional fields, but do not (nor does it promise to) go into explaining why that's happening. :\
quantisan··on The Psychology of Japanese Train Stations
I witnessed a group of 20+ Latin American tourists boarding at some station and then getting off at Shinjuku the other day. One of them held the train door with his body while all 20+ of them strolled in the train nonchalantly. Then the same door blocker proceeded to scream out instructions to the rest of the group. They did the same thing on the way out.

Usually there's a smooth flow of people entering and exiting as everyone seem to know where to go (left or right) because there are maps of train car # to every other station's exits on the line. While they were figuring out whether to go left or right on the platform, they were blocking everyone on that side of the platform right at Shinjuku (literally the busiest station on Earth).

There are dozens of lines criss-crossing the city and every one of them is running accurate to the minute. We take it for granted living here. But boy, when articles like this come around every so often, mind blown. I never gave the crowd behavioural aspect of this system much thought. But this article reminded me of that incident with the tourists. It's impressive how behavioural quirks of the commuters are critical to the overall efficiency of the system. (obvious in hindsight)

Thanks for sharing!

quantisan··on Privacy Loss in Apple's Implementation of Differential Privacy on MacOS 10.12
Let’s say you wanted to count how many of your online friends were dogs, while respecting the maxim that, on the Internet, nobody should know you’re a dog. To do this, you could ask each friend to answer the question “Are you a dog?” in the following way. Each friend should flip a coin in secret, and answer the question truthfully if the coin came up heads; but, if the coin came up tails, that friend should always say “Yes” regardless. Then you could get a good estimate of the true count from the greater-than-half fraction of your friends that answered “Yes”. However, you still wouldn’t know which of your friends was a dog: each answer “Yes” would most likely be due to that friend’s coin flip coming up tails.

Because LifeLock is an identity theft insurance company. They help to get your identity back and pay for all the cost, up to $1M. People buy that.
quantisan··on Brain implants allow paralysed monkeys to walk
"The problem I see with this is that they implant monkey before paralysis and can use machine learning to build a model of the monkey's unique representation for walking. Then they paralyze and show the monkey's can adapt to only using their interface in 5 days. There's no way the mapping from neural activity to stimulation is generalizable..." [1]

quantisan··on Ask HN: What system do you use for tracking and annotating academic papers?
I use Papers too. I've set it up so that all my loaded papers are automatically re-saved in a structured library as plain PDFs /Category/Year-Author-Title.pdf. That library folder is on my Dropbox. So I can access it anywhere else without Papers installed.
quantisan··on Ask HN: What are the interest rate increase effects on VC?
Depends on how much of the increase. If it's small increment, businesses have factored that in. If it's more than expected, then opportunity cost would increase thus making it harder to get money. http://ig.ft.com/sites/when-rates-rise/#faq-are-businesses-r...
quantisan··on Kinto – open-source alternative to Firebase and Parse
Great! We run Firebase in production. Offline-first is one of the most important features for us. (I know, Firebase isn't there yet) I'm surprised this isn't showcased more prominently on their marketing.

quantisan··on Ask HN: Do you listen music while programming??
Always. I like upbeat foreign music (e.g. Korean pop) that I don't understand the language so it doesn't distract me. And Deep House.

quantisan··on The Cheap Phones Quietly Winning the U.S
I had a ZTE Monte Carlo and used it for 3 years. It's surprisingly durable as a device. Everything works and there're minimal physical damage after my careless use for 3 years. Whereas my other Chinese brand phone (Umi) had more and more problems as it wears out just 1 year after.

quantisan··on Why we travel
I've been traveling in Europe for 2 months now. Writing this in Gothenburg, Sweden. Not taking the plane since I've arrived and have taken my leisurely time across 8 countries serendipitously around Eastern Europe and Baltic. What I've come to realize is that travel disrupts my notion of normal. As Alan Kay puts it, "normal is just a construct".

Everything are different when you're traveling. From the obvious like language and culture, to the subtle like where to buy fruits. I feel like a child again when everything is new to be experimented.

That breaks down my usual routine and my expected notion of self completely. I am more stimulated, creative, self reflective, and outgoing (as /u/Paul_S also mentioned).

It's like when you move to a new team / school or fall in love with someone new. The first few weeks/months is like a Wonderland.

quantisan··on Ask HN: Does HN bump up local content based on your location?
yes, that's probably it. Thanks for responding.
quantisan··on Front Page Subreddits Go Private in Response to Firing of Reddit Admin
From the post:

"As much as Victoria is loved, this reaction is not all a result of her departure: there is a feeling among many of the moderators of reddit that the admins do not respect the work that is put in by the thousands of unpaid volunteers who maintain the communities of the 9,656 active subreddits, which they feel is expressed by, among other things, the lack of communication between them and the admins, and their disregard of the thousands of mods who keep reddit's communities going. /u/nallen's response above is an example of one of the many responses to these issues."
