motivic··on The startup economy is fundamentally broken and the virus will make it worse
Supershuttle which offered shared vanpool rides to and from airports all across the US was shuttered partly because of competitions from Uber [1]. I personally find it a useful service given you can schedule it for early morning flights (6AM or earlier) without worrying about availability of drivers.

motivic··on Zoom Acquires Keybase
The CEO of Zoom is a naturalized U.S. citizen. He is ethnically Chinese but by all means he is no longer legally a Chinese citizen.

motivic··on A Graduate Course in Applied Cryptography
A 4-credit course is $5000 and a 3-credit course is $3900 (don't ask me why the cost per credit for each are not the same). There is also a one-time $200 transcript service fee.

With that said, if your employer has an educational plan that can cover the cost, then it is definitely worth pursuing. I am working on a AI graduate certificate and have just completed CS 221. The level of rigor in instruction and course work is far better than any online MOOC course I've taken.

motivic··on There’s No Winter Break from ‘Publish or Perish’
Exactly. I used to be a mathematician and while I am no longer one, I can completely empathize with wanting to work on math as much as possible. To me, it's exactly the same as why some people want to run marathons, because it's exciting and immensely rewarding, and makes me feel alive.
motivic··on Is Artificial Intelligence Good?
Are nuclear bombs good? In the end it largely depends on how they are used.
motivic··on Gitlab: don't discuss politics at work
In that case one can just spam the same (or similar) post every second and your feed will likely be filled with that post.

I know I'm setting up a bit of a straw man here but my point is even chronological order can be exploited.

motivic··on Gitlab: don't discuss politics at work
> unless they started to select and/or moderate that content, at which point they would lose the carrier status

But since the homepage feed (or any medium really) displays contents in a certain order, some selection must take place.

Typically some algorithm (usually a recommender system together with some business logic) is used to determine which contents from all that's available to you are actually shown to you and in what order.

Bias seems to be an unavoidable part of the design to me.

motivic··on Uber Health
Curious how Uber is planning to ensure the service 24 hours available? Anecdotally, it has been difficult recently getting rides before 6AM in the morning on a few occasions.
motivic··on What Happens to the Body on No Sleep
In case you feel sleep is a waste of time, it could actually be surprisingly productive to sleep. Once thing I noticed in grad school is that your sub-conscious is passively working on the problems you encountered even if you are not actively thinking about them. And often I would "dream" up a clever solution to a homework problem during my sleep.

J.P. Serre, one of the most brilliant mathematician still living today, purportedly "does all his best work in his sleep": https://tinyurl.com/y25q45ut

From what I learned in the wonderful Coursera course: "Learning How to Learn", these are manifestations of the unfocused or diffused mode of the mind, and play a critical role in learning and problem solving.

motivic··on Tesla’s Autopilot Could Save the Lives of Millions, but It Will Kill Some First
Tesla's Autopilot has purportedly caused crashes already: https://www.bbc.com/news/technology-49594260

Good news is there were no injuries in this incident.

But there are also cases of fatality blamed on Autopilot: https://www.bloomberg.com/news/articles/2019-05-01/tesla-sue...

motivic··on Anaconda Peter Wang Stepping Into CEO Role
Corrected. Sorry for any confusion caused.
motivic··on Fallout from Blizzard Hong Kong Incident
I am a Chinese American but my wife is Chinese. I have a large number of Chinese friends. You may be surprised to learn that vast majority of Chinese natives are very pro-China; and while they can be critical of the Chinese government at times, they tend to be united against any actions taken by foreign entities they consider anti-China or anti-Chinese government.

Talk to a few Chinese immigrants and you will know.

The younger Chinese generation grew up in an era of Chinese economic boom and are the benefactors of the efficiency in decision making that came with a more top-down (dictatorial if you will) government. The younger generation is much more focused on economic well-being and safety over liberty or freedom.

So as long as China can maintain the economic growth it's been having the past two decades, the Chinese public will by and large support the government.

Don't judge a paper (solely) by the number of citations.

"YC YC YC YC YC" gets you 99.9%!!

edit: "YC YC YC YC YC YC" -> 100%

motivic··on These Are the 25 Best-Paying Jobs in America
A bit disappointed that the tech-related job titles on the list have so much overlap. I mean, "Enterprise Architect", "Software Architect", "Solutions Architect", "Data Architect", and "Systems Architect"? The distinct is not clear to me.
motivic··on Why Facts Don't Change Our Minds
Case in point: All religions.
motivic··on Why Facts Don't Change Our Minds
All these discussions remind me why I loved pure mathematics so much. Every theorem requires a proof, and nothing is really a fact on its own, but a logical derivation from an assumption. I guess you can call these "2nd order facts"?
motivic··on Some Reflections on Being Turned Down for a Lot of Data Science Jobs
A better but more difficult approach is to distinguish oneself and have the companies go after you.
motivic··on Some Reflections on Being Turned Down for a Lot of Data Science Jobs
This is a bit off-topic but one thing I'm curious is how the author manages to interview with these companies while holding down a full-time job and keep up-to-date with the latest developments. Interview for a data science position is typically a drawn-out process, with multiple rounds of interviews and possibly take-home projects. I found them to be very time and energy consuming.

To share my story, I also had a difficult time transitioning into a data scientist role after leaving academia (pure mathematics), and I always thought the root cause was my lack of experience and competency. So instead of keeping on applying, I spent over a year just to sharpen up my skills. It paid off in the end.

How can one develop his/her skills and cultivate expertise if one is job-shopping all the time (possibly aimlessly)?

motivic··on CodinGame – Practice coding with fun programming challenges
My bad. I did not see the language choices in the select menu are not alphabetized. Should have looked at it more carefully before commenting.

Also Python is version 2 and not 3.
motivic··on Amazon Looking to Buy Capital One?
If only I'm as opinionated and eloquent.
motivic··on Amazon Looking to Buy Capital One?
I work for Capital One, and this is almost surely pure speculation. I wouldn't even call it rumor because there is no trace of evidence to this speculation.

I say put your skeptics head on if the title of the article ends in a question mark (and also sources cited do not directly discuss the matter at hand).

motivic··on Amazon looking to buy Capital One?
Not exactly fake news but definitely tabloid.

motivic··on Show HN: Insight AI – 7 week fellowship for scientists and engineers
This is a very interesting program and I imagine there will be lots of applicants. So this leads to my question, how many fellows will be accepted to each session? Also, for those of us who see this as a life-changing opportunity, what would you suggest we do to improve our chances of getting accepted and successfully completing the program?
motivic··on Ask HN: Got into Udacity's Self-driving car engineer program. Should I accept?
I'm in the same boat. I plan to try it out for a week and request for a refund if it doesn't meet my expectations.
