cellar_door··on Uber cuts 3000 more jobs, closes 45 offices
If you've worked at big companies on products with millions of users (like OP with Uber, Intuit, and Tesla), can't you just detail the specific team and components you developed?
cellar_door··on Vitamin D and Inflammation: Potential Implications for Severity of Covid-19
I don't know how you can take this data seriously. It's comparing population Vitamin D levels vs. population COVID mortality for n = 12 countries.

Are studies like this done to justify an actual Vitamin D study? They need to take a sample of confirmed COVID patients and test their Vitamin D levels individually.

cellar_door··on Some overwhelmed parents are abandoning at-home schooling
I'm an only child and had plenty of adult interactions outside of public school. If I was homeschooled I would have been miserable, even if I met people through sports and other activities.

This site is filled with introverted engineers -- not exactly a representative sample. 3.4% of kids are homeschooled, 64% of which are doing so in order to provide religious instruction.

By the looks of the empty premade food section at the Mountain View Trader Joe's earlier today, no.
cellar_door··on Ask HN: Why does anyone still use Medium?
What I find quite annoying is that Medium has clearly spent a lot of effort on SEO. Whenever I Google a technical topic, the top results always include poorly written Medium articles.
cellar_door··on Why databases use ordered indexes but programming uses hash tables
Collisions are expected (fill factors are typically typically 2/3 to 3/4). You make every bucket in the table a linked list. And check each value in the list against that for which you are searching.
cellar_door··on Gitlab cancels plan on tracking user behavior on GitLab.com
My understanding was that Gitlab wanted to collect your data to improve their product. Google is collecting your data to sell ads.

I understand the reticence towards third party telemetry, but refusing basic interaction tracking for a product you pay for is just hurting yourself, even if you're already satisfied with the service. You don't go to the doctor for a checkup and then refuse bloodwork. Obviously there are rules around privacy for medical records that don't exist for interaction tracking. But I don't think the solution should be to get rid of tracking entirely, it should be to extend reasonable privacy rights and protections to our online data.

The Rose and Crown is in Palo Alto? So I guess they've already moved within the Bay before.
cellar_door··on Blowing the Whistle on the UC Berkeley Mathematics Department
His salary is $67,886. Are you really going to hire somebody to do his job for less money than that?

In regards to your points about research, maybe the math department should consider establishing a "teaching professor" role like the EECS department has done. Most of the lower division introductory CS courses are taught by teaching professors like Paul Hilfinger, John Denero, Dan Garcia, and Josh Hug. Given that math is so important to a variety of majors on campus, why shouldn't we demand that large, lower division math courses be taught by people who are experts in teaching?

cellar_door··on The End of College Tuition Pricing as We Know It?
Maybe it's just my university, but I spend 21 hours a week in class, even though I am officially taking 15 "units"). Most STEM classes are a 6 hour/week time commitment even though they are only listed as 4 units officially.

Also, class time is split about 60/40 between professors and graduate (sometimes undergraduate) student instructors. Class size for the student instructors is 25-30 and class size for the professors is anywhere from 100-1400, depending on the class. Some upper div classes are notably smaller, depending on the department. It's my understanding that this setup is pretty common at large public universities.
