The difference is that rust is safe by default. When doing something routine/trivial, you are typically operating with safe code.

Having a minimal runtime is, I believe, a requirement to make any serious headway into a lot C/C++ use cases. The places where minimal runtime is not important have already seen big shifts to garbage-collected languages ~20 years ago.

"I've heard too many times 'just use Postgres', repeated as an unthinking mantra." You use "unthinking" pejoratively, but being able to skip past some decisions without over-analyzing is really important.

Maybe it's one of those things where a good union is good and a bad union is terrible. It's easy to say how good a union could be, but will it actually be that good? What kinds of things can go wrong? What weird laws are in plac

I have a theory that PHP is kind of like erlang -- as a framework and dev environment, not the language itself. Each request is pretty much independent of the others, and each one can independently crash. There was also CGI, but CGI always

Maybe it's worth considering an interface to a big int library that can defer carry work across many operations, and then normalizing at the end? That certainly sounds useful for, e.g., totaling an array of big integers.

Yikes. I was just trying to link to a relevant technique that the author might find helpful. A big integer library may have many use cases; a benchmark only shows one data point. It's possible that by deferring carry work across more o

The article here: https://news.ycombinator.com/item?id=23351007 specifically recommends against the carry variants of addition, because the instructions are still dependent on each other and don't pipeline well. In oth

The more obvious lever here seems to be money. What you are suggesting is very round-about -- somehow slack is so useful that, by denying police its use, they will see the error of their ways? Where does this end? We could also make them we

This is what I don't get: saying they are theoretically good but problematic (without necessarily saying "police are a net bad"), and then saying it's unethical to do business with them for routine products. If there is

I agree that police are the last line of defense rather than the first. Many places would be quite peaceful without police, though it might depend on the timeframe. Bad actors can do an awful lot of damage, and you really don't want Ho

I'm just trying to figure out why it's bad that police use slack. If we don't want police to be able to communicate, why not just disband them? Note that I'm not suggesting we disband them. I am just trying to follow the

In response to persistent injustice by police, there are really only a few options: (a) Get used to it. (b) Get ready to join up. More officers who care about justice mean that it's easier to get rid of the unjust officers. (c) Get rea

If your city had a ballot initiative to defund and disband the police department, would you vote for it? EDIT: I'm a little confused about the downvotes. If the answer is "no", then what's the problem with police using s

by jeffdavis 6y ago
Are we saying that: (a) police are a net good, but slack is aiding/encouraging particular bad behaviors; or (b) police are a net bad and we should just deny them anything that enables them to do their jobs; or (c) police are a net good

Why do you think I want a violent revolt? If you can protect yourself, you can simply (along with fellow voters) abolish the police. Once they stop getting paychecks, they will go home peacefully. Without private gun ownership, abolishing t

To me that's very up-front. There might be a lot of people who would try to hide disqualifying information, hoping you don't find it. There are probably a limited number of landlords who rent to felons, and they have to just make

Let's say that there was the "perfect" non-lethal weapon. Kind of like a phaser from Star Trek set to "stun" mode. Would that be a good thing? I imagine there would be a lot of cases where they just stun everyone be

Self defense is the general principle, and one of the things it offers is independence from the police. A long time ago maybe that meant not having police at all, today it means that the police can be fired.

The point is, if citizens are armed, they can keep the peace (more or less) without police for a while.

No. Without the second amendment, you are dependent on police for safety -- so dependent that there is little you won't put up with. With the second amendment, you can simply fire the police without (as much) worry for your family&#x27

The fact that it was used in '92 for riots means it will be hard to challenge. I feel it is an afront to the Constitution and the founders' intent, though. The Second Amendment is there, in part, to avoid the need for a standing m

Should people write programs differently than before, or just use existing concurrency constructs and things will execute with better parallelism?
