brickteacup··on Best engineering interview question I've gotten
> Multiple clients racing can't be fixed.

Really? You can't think of a single way for multiple clients to operate on the same data without racing? (Here's a hint if you're still having trouble: https://github.com/memcached/memcached/wiki/Commands#cas.)

"Expecting basic programming ability" isn't elitism, sorry
brickteacup··on Best engineering interview question I've gotten
I actually can't tell whether you're serious...

The article mentions an `append` operation which is obviously not commutative; does that imply memcached needs a separate "appendable" string type? Of course not. Memcached only guarantees that the individual operations are atomic, it's the client's responsibility to avoid race conditions between multiple operations.

brickteacup··on HTTP/2 and HTTP/3 explained
Yes, bytes from a *logical* stream need to be delivered in order. But in HTTP2 (3) multiple logical streams are multiplexed on top of one physical TCP (QUIC) connection. In the HTTP2 case this means that a dropped segment from logical stream A will block delivery of subsequent segments from an different logical stream B (which is bad for obvious reasons). QUIC doesn't have this problem, which is a large part of its value proposition.

> The point is that in some cases the name of the project might itself be considered sensitive in some way

probably better to solve that problem by just giving projects easy-to-remember codenames. that's what intelligence agencies and militaries have been doing for years after all

brickteacup··on BlackCat ransomware group implodes after apparent payment by Change Healthcare
I agree. Actually everyone I don't like should be classified as a terrorist and denied any sort of due process or civil rights. It's fine as long as we only do it to really really bad people who make us very very mad.
brickteacup··on How to find the AWS account ID of any S3 bucket
it's irrelevant whether they're "cryptographically" random, all that matters is that account IDs are not controlled by the user and therefore have no logical relation to any access-control policies the user may wish to implement
brickteacup··on Almost every infrastructure decision I endorse or regret
That's only for data into AWS though, not data out
brickteacup··on An ideological divide is emerging between young men and women around the world
Yes we all know it's possible to lie with statistics. What are your criticisms of this article in particular? If you don't have any then you're just baselessly casting aspersions.
brickteacup··on Maybe Rust isn’t a good tool for massively concurrent, userspace software
No? You don't need parallelism to guarantee global progress as long as the scheduler has the ability to preempt tasks. Of course coroutines (as opposed to e.g. userspace threads) can't really be preempted, which is the issue here.
brickteacup··on AI bots are now better than humans at decoding CAPTCHAs
> These are where the news site makes their content available to scrapers and then paywalls humans. This is where the news site is trying take advantage of search engines to get you to clink on their SERP, and then make you pay. In a lot of cases you can read this content by proxying off a non-dynamic ip range and changing your user agent.

okay... so they're piracy links is what you're saying?

> extremely weird conclusion

I agree, it's so weird that people who devote time, effort, and resources to the production of articles or books somehow think they're entitled to be compensated for the use of those products! What a bizarre belief! I mean, obviously they should just give them away for free. Not like they need money to survive or anything. They can just go on food stamps and live under a bridge or something.

> but it seems more unreasonable to expect anything different from the oligarchy

oh my god when the demand for a scarce resource outstrips supply, prices go up. this is high school microecon, not some conspiracy by tHe oLiGaRcHy

brickteacup··on AWS to begin charging for public IPv4 addresses
If only there were some sort of a system for translating human readable names to network addresses...
brickteacup··on AWS to begin charging for public IPv4 addresses
Not to mention the absurd fact that accessing (IPv4) AWS APIs from a private subnet requires paying for either a NAT gateway or an interface endpoint (we got bitten by sending a ton of Kinesis traffic through a NAT gateway once)
brickteacup··on Adtech is built on a privacy fault line
They didn't, though, they made it available to be looked at alongside advertisements.

HN users just love twisting themselves in circles to justify their belief that they're somehow entitled to consume content from private websites without consuming the ads that support that content. (If you don't want to see ads, there's a really simple solution: don't look at websites that display them! No one's forcing you to!)

> On Facebook if you want to reach your entire audience you need to pay them

Yeah, it's a private business, if you want to use them to reach people you need to pay. What exactly is wrong with that?

> regular methods of discovery

What are these "regular methods of discovery"? Do you think that small businesses didn't advertise before Facebook/Google/etc came along?

> doesn’t entitle them to my attention

if you're looking at someone's website then yes they are entitled to your attention. what gave you the idea that you're entitled to consume for free content that other people payed to produce and host?

brickteacup··on Can you trust a compiler to optimize your code?
> ML systems do not guarantee valid output

no one said this has to be an LLM or whatever. you could have a compiler that just uses ML-based cost heuristics. iirc some research has already been done in this direction

> Yet I’m powerless to do anything about it.

it's called a chargeback. the worst they can do is ban you from their platform

brickteacup··on AWS: IPv4 addresses cost too much, so you’re going to pay
> Pretty exorbitant pricing

good, clearly no one is going to start implementing IPv6 until using IPv4 begins to hurt

Well you see, war rape is actually not a women's rights issue. After all, women aren't raped because they're women, they're raped because they're women from the opposing side. It's completely different!

(Before anyone takes it seriously: this is a parody of how stupid the parent sounds.)
