The closest large city to me is Oakland, which spent $750m on schools last year: https://oaklandside.org/2022/01/12/oakland-schools-are-facin... So this cost 13% of one years spending in a mid-size district.

Unlike Clear, precheck is trading an up-front background check for a less involved inspection when traveling. I'd imagine if it was up to the TSA everyone would do precheck.

I used/worked on a similar async model at FB long before I'd ever touched node. Threads are not really solving the same problem as async. Imagine you are building the FB newsfeed. You have 10 stories and want to fetch them as qu

The FDIC insurance fund is paid by banks, so ultimately depositors were "bailed out" by the broader banking industry.

Ah, I see, sorry for missing your point. In the paper they injected particles of size "9.55 µm, 1.14 µm, 0.293 µm", and it looks like a red blood cell is 8um. So a purely mechanical filter that got red blood cells would retain t

So you filter out the blood cells (45% of volume), toss the plasma (55% of volume) and return blood cells + clean plasma. Any substances the plasma are gone. So this is useful to the extent that the substances you care about are free in p

They don't filter the plasma, they remove it and replace with some other substance depending in your condition and risk profile.

nit, but this is usually accomplished with plasma donation (plasmapheresis) rather than blood donation. You can donate plasma much more frequently (2x/week) vs blood (once per 2 months), thought the volume taken for each is roughly si

This is great data. I think the figures, particularly fig 3, tell the clearest story here. Wage percentile is monotonic in cognitive ability between the 10th and 95th percentile of income. You could imagine that in the top percentiles ot

I used FB Workplace while at FB and strongly prefer it to Slack. In Workspace there's a clear delineation making a new post and replying to one; this means it's easy to skim through new posts in a group to catch up, and only dig

It's an API limitation afaik, not tied to whether you pay.

Note that the Google Photos API which rclone uses for gphotos sources does not allow downloading original quality images (only re-compressed versions), and strips EXIF. So I personally don't use it for backup purposes, instead I: 1) S

Is there precedent for holding the board personally liable for something like this? That seems both morally questionable, and with lots significant negative effects to how organizations run.

I wonder if it's feasible to make many sets of platters share a single set of heads? Similar to tape, but once the heads are mounted to a specific set of platters you get disk-like latency. Keeping the environment inside the drive cle

Ok I see what you're getting at. Yes, there are plenty of VR apps that don't require that kind of latency control. A game that's 99% local, but shows you a leaderboard of top scorers, etc. Even an app that has a significan

This isn't about saving 10ms in latency. In the case of a dropped packet, TCP can wait multiple seconds for a retransmission which blocks the whole stream. You aren't going to client-side-predict your way out of that. QUIC in

Just having UDP somewhere in the stack isn't sufficient. The reason game protocols use UDP is because (among other things) they can precisely define when to block on missing data and when to ignore it and keep going. For example, lets

Do you think every price should be set according to marginal cost? Since the marginal cost of a chip is extremely low after you've paid for the fab and design costs, should those be free as well?
