I love Noam Chomsky so much. To me he is epitome of what a rational caring intellectual should be. Number one, he strives for the truth and while can have intellectual blind spots, isn't afraid of calling them out.
We had him has a guest speaker for an internal presentation at Google and of course we had some hyper-rational libertarian eastern block swe kid who was going to take him down and Noam was super respectful, spared with the kid for awhile and then changed the subject slightly while destroying the libertarian kid's entire argument.
9's are overblown. When cloud providers report that, they're really saying "Assuming random hard drive failure at the rates we've historically measured and how we quickly we detect and fix those failures, what's the mean time to data loss".
But that's burying the lede. By far the greatest risks to a file's durability are:
1. Bugs (which aren't captured by a durability model). This is mitigated by deploying slowly and having good isolation between regions.
2. An act of God that wipes out a facility.
The point of my comment was that it's not just about checksums. That's table stakes. The main driver of data loss for storage organizations with competent software is safety culture and physical infrastructure.
My experience was that S3's safety culture is outstanding. In terms of physical separation and how "solid" the AZs are, AWS is overbuilt compared to the other players.
We experimented with doing ML training with it, but it's not clear that it trains any better than a non-broken PRNG. It might be fun to feed the output into stable diffusion and see how cool the pictures are, though.
This is actually incorrect, as per Postgres docs `timestamptz` is always stored as a UTC timestamp.
The benefit to this vs a regular timestamp is that when you insert/update a timestamp value, Postgres can then convert that timestamp to UTC if necessary before storing it, and if you select a timestamp value Postgres can convert it from UTC to the timezone you want.
If your connection is set to use UTC, and you always handle UTC timestamps, there probably isn't much practical difference between `timestamp` and `timestamptz`, however.
You're right that the US is a fabulously wealthy country. Still, this might be a misguided comparison: the least developed region of NZ still has a higher HDI than two US states[1][2], without considering territories.
If you decided to wander around West Virginia (as I have), you'd see plenty of people burning coal and/or firewood for heat in winter (and WV winters are much harsher than NZ ones, from what I know about NZ). You'll also see extreme indigence of a sort that's otherwise almost completely invisible in the US.
Why is the answer to this question always “Safari sucks”?
Are there no good PWAs that run on Android? Are there none that, though perhaps smaller is scope, run well in Safari?
People have been advocating for PWAs for a very long time now but it’s incredibly hard to get examples of good ones. There is always some complaint about Safari instead.
> [Regarding SSB:] It insists on having a chain of updates from a single user, which feels unnecessary to me and something that adds bloat and rigidity to the thing — each server/user needs to store all the chain of posts to be sure the new one is valid. Why? (Maybe they have a good reason)
I think the reason for the chaining is that it creates a causal ordering of posts. You will never see the n+1th post without also seeing the nth post.
Not having this means posts being dropped by a peer for some reason may change the meaning of the sequence of posts in the eyes of the readers. Imagine for example sending "The previous post is a joke." If posts aren't chained cryptographically, there's no way to know that you have a complete sequence of previous posts, or if some are missing.
Please forgive me for asking a controversial question (particularly so early in the morning), but if there are all of these biological correlations with race, what does it mean that “race is a social construct”? Is the idea that black people have greater bone mineral density (per TFA) due to social or environmental causes (e.g., diet)? For what it’s worth, I’m a staunch egalitarian and I don’t see that changing either way.
EDIT: Really pleased with the largely constructive conversation in this thread. Was worried that this was going to be coopted as an ideological flame thread. Thanks for the insightful answers and good faith engagement. Keep up the good work!

You don't just debate Noam Chomsky.
