They quite possibly aren't capable of being concerned about it. We are.

This is just the is-ought problem, or naturalistic fallacy. That my cat, or any other animal, kills things in order to eat them in no way obligates me to do so.

Which justifies precisely nothing. Morality is about what you choose to do.

It's not whether nature has other or better options. It's whether we do.

On the contrary, many indigenous peoples were and are acutely aware how much their well-being depended living within the carrying capacity of their environment. Many also weren't , of course, but it's silly to make a blanket proc

It's less fun to consider that most of the Eastern half of what is now the United States was also a vast forest, until European settlers arrived and clear-cut it, first for agriculture and then for industry. Edit: Yes, the indigenous p

They aren't just paying "with their attention" — but also with having all of their behavior, across the entire web, recorded, tracked, and modeled by folks with demonstrably unclean hands, whose incentives are aligned agai

I'm paying Sonic ~$100 for 12 down/2 up bonded DSL, and two phone lines I think I've used one of, about twice. I'd still rather give them that money than Comcast any .

By analogy: I used to have incredible direction sense. On one of my cross-country drives, a couple decades ago, I made it to my friend's place, having only vaguely consulted at an atlas a couple of times. I lived in New York; she lived

Disagree. It's im pertinent, both in the sense of its being off-topic for the technical achievement in The Fine Article, and that of its being ill-mannered. I say that as someone who assiduously avoids using Uber's services, wh

Thanks for the correction, Robert! Now I'm curious where I got that notion.

That sounds like operator error to me. If you (the general "you") use a database in production without knowing what sorts of maintenance it requires, that's neither the database's nor its authors' fault. I guess you

Can you point out where I dismissed anything? PostgreSQL has a write-amplification issue — especially when you index every column on a table . My point is: if you don't do that, it doesn't hurt.

So, basically the already-existing Visibility Map? Indexes in postgres point to the page , not the tuple . The VM keeps two bits per page: "does this page have any 'dead' tuples?", and "does this page need to be t

...all of which structures you'd somehow need to synchronize writing to, to keep them accurate and fresh. Global write-locks do not scale, no matter how fast it might be in the toy case.

by rosser 9y ago
Wouldn't a write lock on that structure become a hotly contended resource? Globally shared, globally writable structures tend not to scale very well. Postgres already has the notion of creating and destroying transaction ids for each r

I wouldn't characterize things as "falling over", except perhaps in cases of operator incompetence. There's certainly room for improvement — The Fine Article wouldn't exist otherwise — and backpressure might be wort

Are you legit suggesting tying the cost of GC to transaction commit in a database platform that is very commonly used for OLTP workloads?

Uber's explanation of the problem neglects to consider their poor usage of the tool as contributory to the problem.

Writes in postgres touch all indexes. When you index every column, you have to touch every column's index for every write. Writes in MySQL (using InnoDB) just touch the pkey index, to which all other indexes point, or something like th

Vacuuming is not why Uber flounced off PostgreSQL. They were naïvely using it as a KV store, and indexing every column, which caused a write-amplification cascade. Edit, re: the parent's edit: Quoting that article, "Perhaps the th

We've found that periodic invocations of pg_repack are necessary to keep things from bloating beyond the inflection point where vacuuming just can't keep up. I'd love to see VACUUM somehow able to take care of that, because t

Negligence is not "really really hard to prove". In the US, negligence as a tort is a four-pronged test. In the case of Equifax, did they have a duty to protect your PII? Did they breach that duty? Was that breach the proxima

Rather damning: "Krzanich's [Rule 10b5-1(c)] plan was created on October 30 and by Intel's own admission, the company learned of the chip vulnerability in June."

Can you clarify what you find valuable about it? I find it utterly hand-wavy, it calls people "hysterical", and then goes off-topic to complain about moderation.

by rosser 9y ago
No, "critical thinking" is evaluating ideas and arguments, including one's own, for flaws. That you conflate it with engineering further suggests that you don't actually know what it is, and continue to over-value the &q
