Has network latency improved much since this article's date? Bandwidth definitely, but latency?

What was the salary range?

Most rankings / evaluations will be subjective with or without a rubric.

Are they even hiring at this time?

Interesting idea. Many years ago when I was learning French I seemed to speak it much better after a drink or two with a French speaking neighbor. Maybe it was less worry over gram…

I used a friend's xanax. Admittedly I should've trialed it beforehand, mistake on my part. I just remember feeling a really strong relaxation and nothing afterwards. I did get an o…

This a good a solution that extends to other aspects of a job as well. It also doesn't lead to possible dependence like other solutions.

I would advise strong caution against this unless you have used any benzo before. I remember I tried one once before a long, 4 hour interview. I literally don't remember a thing I …

I agree with this. Interviewing is a skill like any other that can get stale. It's good to keep it sharp and you never know, while practice interviewing you might find a place you …

Go to a derm/doc to see if there are any nutritional deficiencies (unlikely though). Once that's ruled out, get on Finasteride. 99% of people maintain their hair. Unless you're sli…

I think the wiki explains it well https://wiki.postgresql.org/wiki/Index-only_scans#Is_.22coun... It says that index only scans can be used with predicates and less often without p…

Apologies, I should've clarified. I just meant postgres doesn't necessarily have to scan the actual table to get the count in some cases if an index is available, not that it cache…

Not necessarily in postgres. If an index is available it may use that, though it will still have to refer to the visibility map to see if any row is available to the current transa…
