dotopotoro··on What every programmer should know about solid-state drives (2014)
> True, but you're using so many abstractions that the rule can't feasibly be "read a short summary of every abstraction you're using."

Rule - no. Goal - yes.

Some topics are more stable and valuable then others, so prioritisation helps.

“How utf8 generally works” vs “implementation details of js-node-utf-related-library-X.”

One topic at high level (like in the article, 10-20 minutes?) per week, results in ~50 topics per year.

Not sure how many computer related topics you know/want (“The more you know, the more you know you don't know”), but for me, 50 topics on programming seems sufficiently high at frankly a very low effort/commitment.

Databases always try to flush something to disk after transaction, just in case unexpected reboot happens. So your writes to db have direct correlation to disk writes.

Choice of db schema impacts physical layout on ssd. E.g. Different tables are more likely to be on different ssd pages resulting in random writes.

Databases are insanely complex, but not magic.

“don't need to know anything about it” is acceptable, but should not be encouraged.

It’s not like reading 10 bullet points on the subject is “diving deep” and making huge time investment.

It’s just getting the minimal context, so later on at least some keywords are known.

Also, It was decommissioned then reinstated. However it was still a flagship.
dotopotoro··on The Coming Food Catastrophe
You are right. Add to that, the constant and persistent info flow from russian media and incentives to “say the right things”, which raised whole generation.
dotopotoro··on The Coming Food Catastrophe
> the war should end asap, no matter who wins

One part of me agrees with this. War is the worst (as far as i know from books and tv).

The other part of me thinks: That is how Germany expanded half a century ago, getting resources for ww2. (thug perceives the pacifist as a weakling and an easy opportunity to profit). Ukraine has a lot of natural resources, part of the reason for the war.

dotopotoro··on Unsolved problems in economics
Nice example.

Economics almost by definition can not make good predictions wanted by the public, because as soon you figure out precise model “a” of the economy, the economy takes the model “a” into account and mutates to model “b”.

dotopotoro··on Unsolved problems in economics
What kind of precision of prediction is required? Economics predict some things. For example if you print exceedingly a lot moneys, inflation will happen.

At the same time, physicists have problem telling precise location and momentum of the atom (at the same time; precisely).

(footnote: I love physics more than economics, but world is not perfect and sciences are not perfect. Except for math maybe https://xkcd.com/435 . Perfection and usefulness are not the same)

Even if hoarded at the moment, energy spent mining the gold was not lost. Gold can be sold tomorrow for its practical uses. Energy powering Bitcoin transactions is gone. (Like the the energy powering bank servers)
dotopotoro··on Ex-eBay exec pleads guilty to harassing Ina and David Steiner
Why? I sense assumption that decency at the top is required for society to function.

Counterpoints would be (sadly):

a. most of the history is wars.

b. Slavery was a norm for a very very long time.

c. North Korea.

Couple of comments replied mentioning studies in this area, and you dismiss them completely (i.e. you show no indication of any value assigned on points made). Seems like you have very strong beliefs/faith/stake in using antibiotics as tic toc.

Is that real? That is so bad. Queue up next “Shall not disclose or notice our incompetence” clause.

That is very rare event with established tooling.

Most of the time complexity is just shifted around.

dotopotoro··on Moskva cruiser sank while being towed in a storm – Russian Defense Ministry
You’ve miss-interpreted the reason for minuses.

The disagreement is with implying that both sides of war are equal.

While there are no saints, only one of them chose to start the waste (see also: Chechnya, Georgia)

dotopotoro··on Moskva cruiser sank while being towed in a storm – Russian Defense Ministry
I’ve read that Turkish vessel took only 75 evacuated persons, while sunk ship had crew of approx 500.

Drone possibly was scrificial. Satellite is not on demand and not in ukraine possession and would not show much after moscow sank.

Kind of true, but only one of the sides is instigator, and tries to repeat kaliningrad‘s cleansing.
dotopotoro··on Moskva cruiser sank while being towed in a storm – Russian Defense Ministry
Just some notes. It was a flagship of black sea fleet. It had crew of approx 500. After the event, russian ships started keeping greater distance from Ukraine.

Definition of “fair” is similar to definition of “random”.

Both terms are very ambiguous, unless qualification is provided.

Random variables can have many distributions e.g. Poisson, Gaussian, uniform.

I don’t know names of categories of “fairness”, but clearly you and GP have different meanings for the same word.

On one end of the spectrum seems to be: “fair == same end result” -> effort and luck should not matter, not in the slightest.

On the other end of the same spectrum: “fair = same system/rules” -> you could have racketeered more people to get more money and bought a bigger gun to stay alive.

Both definitions of “fair” are equally valid, the choice of the definition is subjective.

“Yanukovic was ousted by force”, does not describe the situation. Yanukovic tried silencing protesters using force, but they didn’t surrender.

How russia comes into this list? Which regime was installed by the west?
dotopotoro··on In Africa, U.S.-Trained Militaries Are Ousting Civilian Governments in Coups
Even if it were grass root movement (could be possible, though somewhat doubtful) in donbas and crimea, they didn’t start with peaceful protest demanding early election or greater autonomy or something democratic. There goal clearly was to chip away the territory from ukrain.

Please read up on what happened just before maidan, how yanukovich decided not to sign treaty with eu at the last minute, obviously against people will.
dotopotoro··on Ask HN: Why are chess problems attack oriented?
1. Attack puzzle has more clearly defined solution.

2. There is no difference between attack puzzle and defence puzzle, in the sense that mentally you must play both sides - choose optimal moves for the defender.

dotopotoro··on In Africa, U.S.-Trained Militaries Are Ousting Civilian Governments in Coups
No idea about Libya situation, but in Europe, people wanting side with the west is very natural choice.

Please compare Ukraine’s or Belarus or Moldova’s situation (politic/democracy and economic) with any EU country bordering Russia.

People see the difference, and want better life for them selfs and their children.
