This feels like a lot of decisions of Musk w.r.t. Twitter have been, impulsive and hastily implemented.

Given that a lot of non-niche modern languages disagree with you and you provide no rationale, I remain unconvinced. Swift, Kotlin, Javascript/Typescript along with some older languages (PHP, C#, probably more) have special null-handli
364.
by dtech 3y ago
NULL/missing is so common that it makes sense to provide special language support, even if you don't have full unions. See e.g. Kotlin and Typescript. What doesn't make sense is to treat a nullable type the same as non-nullab

This isn't security through obscurity at all, the links contain a random secret and aren't public. You might as well say a password is security through obscurity because it can be guessed...

It's not uncommon to provide a way how to do it in standards because it will happen whether you want it or not. See e.g. HTTP headers starting with X- or MIME types in application/vnd.

I wonder how much of that is innate and how much of that is because we're not used to fake pictures on a scale AI will allow yet

I do feel 74 bits per second is enough though. That would require 2^(74/2) = 137 billion UUIDs generated in a single second for a 50% chance of a single collision.

Lucky for you, they also define UUIDv8 as a free-for-all where you can do whatever you want, and nanosecond precision is one of the examples given in the RFC.

But then you have 2 identifiers which complicates everything.

I feel like v7 is almost a strictly better v4. Assuming you can generate a v7 (you have a time source), what are the disadvantages?
374.
by dtech 3y ago
When you sort them they will be ordered by generation time. This is useful in UIs, and greatly improves performance in databases (how much depends on DB and use case).

by dtech 3y ago
Only v6 and v7, v8 is "whatever you want".
376.
by dtech 3y ago
v7 looks nicer since it solves v4's locality issue and you're still a gazillion times more likely to win the lottery than generate a collision.

Which is another weird thing. US declared the space race "won" when they got to the moon, despite being behind in all other milestones like sattelite and manned space flight. If SU got to the moon first US would've ignored it

iPhone has like a 33% market share so I wouldn't call it common if you can't reach 2 out of 3 people on it at least. In contrast, in many European countries Whatsapp has 90%+ penetration [1]. Even where it's relatively unused

by dtech 3y ago
SMS is cheap now but wasn't universally when Whatsapp gained critical mass. Nowadays it's mostly about convenience and features compared to SMS, and iPhone has a much smaller marker share in Europe so iMessage isn't a thing.

I would be so happy if can go back to a world where advertising happens purely based on the content like we've had for ages in TV/radio/magazines. The amount of privacy we've globally lost just for a few advertising doll

Do you have any sources that back up increasing prevalism over better recognition and broader diagnostic criteria? Afaik almost everyone chalks it up to those 2.

In the Netherlands all the big bike brands are doing a lot of E-bikes, and there's a gazillion small competitors who do cheap bikes with mostly off-the-shelf components. The bigger brands include Gazelle, Giant, Batavus and Sparta.

Blitzcaling to achieve monopoly is not the only reason for funding. A manufacturing company like this has high up-front costs for R&D and manufacturing, orders of magnitude more than a typical software companies. You also don't nee

Most other languages agree that checked exceptions are not good by not having them. As for alternatives, Try/Result and similar monads have decent adoption even in Java, but personally I quite like the Kotlin philosophy [1] to not have

You already have to guess. All method calls van throw Runtime exceptions.

by dtech 3y ago
They are so bad even Java stdlib stopped using them for the most part. Nearly all Java 8+ APIs like streams use unchecked exceptions.

North-western Europe generally does a lot less for pain management than US and the rest of Europe. It's a big complaint of expats. I've heard it explained as a cultural remnant "pain belongs with life, suck it up" from p

afaik the person you replied to is wrong, using System.arrayCopy would definitely make a copy and not be optimized away. Maybe poster meant only copying the reference with `char[] copy = original` which indeed does nothing, but that's
