astrodev··on Ask HN: What are you doing for your mental health?
"Overall, the lifetime risk of someone developing colon cancer is 5%. To put the numbers into perspective, the increased risk from eating the amount of processed meat in the study would raise average lifetime risk to almost 6%."

The trick is to be among the first who steal it.
astrodev··on Ask HN: Has anyone had a dispute resolved by Airbnb?
Airbnb doesn't really provide customer support in relation to off-site issues - even if as in my case it involves the host asking for extra payment in cash in direct violation of AirBNB's terms. When you pay hundreds of dollars in fees, you assume they would help, but they are nothing more than a classified site with a payment processing system built-in.

It works well once you have adjusted your expectations. Unfortunately, for many of us, this happens through an incident like yours.

astrodev··on Google Fires Employee Behind Controversial Diversity Memo
I expected any discussion of the memo to be quickly shut down, its supporters classed as filthy misogynists. It was surprising to see over 1,000 comments and upvotes. I'm glad that it's becoming OK to discuss these topics again.
astrodev··on Ask HN: What books are you reading?
Peter Frankopan, The Silk Roads - world history from an Asiacentric perspective.

Harold Coyle, Team Yankee - WW3 in Europe in the 1980s from the perspective of a tank company commander. Poorly written, in my opinion, but the accurate (or so I hope) descriptions of the military tactics and equipment almost make up for it.

James Gleick, The Information: A History, A Theory, A Flood - excellent book about the history of information.

astrodev··on Ask HN: Have you ever gotten the Google 'foobar' challenge? How did it go?
Sorry, I only had one left (you get two for completing the challenge).
astrodev··on Ask HN: Have you ever gotten the Google 'foobar' challenge? How did it go?
Emailed! I hope the link still works.
astrodev··on Ask HN: Have you ever gotten the Google 'foobar' challenge? How did it go?
How can I message you?
astrodev··on Ask HN: Have you ever gotten the Google 'foobar' challenge? How did it go?
I completed all problems in March, but haven't heard anything back. It was fun but much easier than the problems I remember from the high school Olympiad (or I have improved), except for the final one, which was more of a maths question - easy if you know the relevant theorems (I had to google it), virtually impossible otherwise.

I can send you an invite if you are interested.

astrodev··on Crispr’s Next Big Debate: How Messy Is Too Messy?
Yes, thankfully, national sovereignty is still a thing.

Why exactly do you want to invade China?

astrodev··on Ask HN: Women in tech, how do you find non-toxic work environments?
I don't think the remark about antifa was meant to be taken literally. Of course, no one will put it in the job description.

Do you think it's easy to be supportive of the current US president, supportive of Brexit and sceptical of climate alarmism while working in tech (or in academia, for that matter)? I do not find it easy at all.

astrodev··on Crispr’s Next Big Debate: How Messy Is Too Messy?
Are you referring to anything specific?
astrodev··on On average, skipping college and investing tuition costs nets a higher return
If that's the case, then I don't understand why the student loans are said to be such a big burden. It's just another tax, I wish more taxes were voluntary like that.
astrodev··on The Theoretical Minimum
That's quite impressive. Where are you from? I think even Cambridge, which is an outlier as far as the course level is concerned, only uses "Mechanics" as a recommended textbook in the third year.
astrodev··on The Theoretical Minimum
These are graduate level textbooks. There is little point in attempting them without a solid undergraduate background in physics, which is necessary both to understand and to appreciate Landau's presentation.
astrodev··on The Swiss leaks and Panama papers open a window on the tax-dodger’s world
Not naming their foundations after themselves would be a good start.
astrodev··on Ask HN: What is your sleep schedule?
4am-7am - 11am-2pm, all week, very consistent, extremely stable against perturbations
astrodev··on VCs Put $110M into Grammar-Checking Software
It's about half as good as a non-specialist human proofreader (see my post above) for a fraction of the cost. While that's not sufficient for some documents, I consider it (in addition to my own eye for detail) good enough for things like client proposals and my academic work (grad student), not to mention all the real-time (chat, email) applications.
astrodev··on VCs Put $110M into Grammar-Checking Software
I can't make any general statements. I checked both tools against a document that was recently corrected by a human proofreader. Out of six errors found by the human, Grammarly identified three and proselint none.

"only half of the mass if accounted for by the stars", misspelling "if" -> "is"

"in the heath death scenario", misspelling "heath" -> "heat"

"The quantity follows Gaussian distribution.", missing article

astrodev··on VCs Put $110M into Grammar-Checking Software
The negative comments don't make any sense. It's hard for me to understand why a bunch of people who clearly don't understand the domain complain how more informed parties invest their money.

I use Grammarly daily. The subscription is cheap compared to hiring a proofreader, which I used to do. The market for ESL speakers is huge, and native speakers, too, can often benefit from improving their writing.

astrodev··on Ask HN: How you wake up?
Wow, everything you wrote applies to me, including the two alarms and the difficulty getting things done due to being so out of phase with everybody else.

A few months ago I had to work 9-17 for four weeks. With some difficulty, I managed to be on time every single day. I was sleep deprived at the end of it, and reverted to my usual 5 - 8 AM bedtime on the next day.

I don't enjoy it but I have never managed to keep a sleep pattern resembling normal for more than a few days.

astrodev··on How I went from failing every interview to a job at Amazon
Well, Coursera has a course in interviewing for software engineering jobs.
astrodev··on How many jobs really require college?
What makes you think that you would have done better in a brick-and-mortar programme?
astrodev··on Should economists be more concerned about AI?
Bill Gates said so, so it must be true.
astrodev··on Depression as hard on the heart as obesity and cholesterol
Actually, the paper this article is based on suggests the opposite:

"Only a minority of 5.6% [of those who later experienced a lethal CVD event] were free of any risk factor. This challenges claims that CVD events commonly occur in persons who have not been exposed to a major risk factor." (where the risk factors include high cholesterol, obesity, hypertension, smoking and diabetes)

astrodev··on Depression as hard on the heart as obesity and cholesterol
It means that there is a correlation between "depressed mood and exhaustion" and cardiovascular deaths. The paper does not demonstrate a causal relationship between the two.
astrodev··on Depression as hard on the heart as obesity and cholesterol
From the paper (DEEX - "Depressed mood and exhaustion"):

"Nonetheless, adding DEEX to a risk score based on classical risk factors resulted in only nonsignificant improvement of mortality risk prediction."

Regarding the causal relationship:

"Although not a proof of causality, in general, depressed subjects are more likely to cluster self-harming lifestyle behaviors and may be less likely to adhere to prescribed medication."

To put things in context it is also worth noting that, except in old age, a big increase in the risk of death at any given point of time translates into a very small reduction in life expectancy. See for example http://joshmitteldorf.scienceblog.com/2012/11/10/mortality-a...

astrodev··on Ask HN: What can you do in one language that can't be done as well in others?
You can easily create domain specific languages in Scala using operator overloading and implicits.
astrodev··on Ask HN: What can you do in one language that can't be done as well in others?
Even simpler, and handles the different new line characters:

  $l = file('in.txt', FILE_IGNORE_NEW_LINES);
astrodev··on What a Sensory Isolation Tank Taught Me About My Brain
> "As quantum mechanics demonstrates, observing changes the thing being observed"

Every single Vipassana practitioner I have met said something of this kind. I know this comes from one of Goenka's recording. But the analogy is bad, wrong, not even wrong, it does not mean anything. As rewarding and beneficial as meditation is to some, please leave quantum mechanics out of it.
