I think that's a symptom, not the cause. The complexity of web standards in general smother it with it's own weight. The common web has enough raw financial and person backing to grind through that. The semantic web does not. CURI

Yeah, I think the regular overlfow is actually an advantage. A.) you pracice having overflows regularly, so the issue is resolved now and not left to some pooor schmuck world war XXVII Survivor in the year 35.000. B.) It uses every bit, jus

That's not even statistics. That's simply the pigeon hole principle. A second has 1000ms. If you have more than 1000 users doing things per second, there MUST be a collision.

> Hashing the IDs won't solve their lack of entropy. Yes and no. It would still significantly largen the search space, as an attacker wouldn't get a point of reference to latch on to.

Nice! This is kinda what I had in mind, while writing that ammendum! Thanks for sharing :D

Have you considered using a 32 bit time value with second resolution? That way you still get sort-ability, you get 16 bit more entropy, fare better on 32 bit systems, and still get 130 years of usage, out of them. Also you actively discoura

Yes, monotonic counters, are ULID's "billion dollar mistake". They're not an edge case, in that the standard displays them quite prominently. They're actually the only code examples given. The standard should deprec

You have to ask yourself the question though. If "URL-Safety" is a main feature. What URLs / user-data are NOT security relevant? Leaking users private pictures / documents / whatever, will also kill a company. I gu

ULID has a serious security flaw though. In order to try to improve performance / increase prefix similarity, there is a mode where it reuses the random value, and just increments it, for each new ULID. With purely random UUID, you can

Premise: A is containing all values in range [1, 4] except one: Let's say that, without loss of generality: > 1 ^ 2 ^ 3 ^ 4 ^ A[0]=1 ^ A[1]=2 ^ A[2]=3 ^ A[3]=4 However, A is now missing no value. Contradiction. ∎

Ah off by one errors are hard: > 1 ^ 2 ^ ... ^ n ^ A[0] ^ A[1] ^ ... ^ A[n - 1] should be > 1 ^ 2 ^ ... ^ n ^ A[0] ^ A[1] ^ ... ^ A[n - 2] Because a 0 indexed array of length n-1, has n-2 as it's last index. After all, it's

This still proves that CSS layout algorithms are O(EVIL). Enumerating and memoizing all possible states will still be impractical, even for small machines.

Politicians inability to tackle an imminent threat like covid has left me completely without hope that we have even a remote chance at tackling a threat like climate change that's taking decades to manifest.

Oh yeah, you're right. Can't tax those billionaires. I completely forgot the paperwork. And those invaluable art collections. You just can't put a price tag on those!

We're not talking about old people here that acidentally stumbled upon something that has really sentimental value to them but is also worth 150 billion. Stop mixing billionaires and millionaires. Having billions is unfair by definitio

It's all about efficient range reads and seek operations. You can compute set operations pretty efficiently using sorted indices that support a "find next or greater" operation. For intersection, take the first value from the

Force them to sell. If there isn't actually the demand at that valuation, then then it's a bubble anyways, that should be popped sooner than later. Also, at that point, you shure as hell diversify your assets, instead of having th

Your argument is the same as saying "but they don't have any money, they only have 65238 metric tons of gold". Money doesn't have any intrinsic value either. You might as well say "societal power" instead of &q

Ha, doubling it, that's cute. The top marginal tax rate in the US used to be 92% in the 50s, and that's what was widely considered it's "golden age". Those 600 people hold $4 Trillion dollar. Which is the federal bu

The last time ULID was mentioned in a thread it got some flack for its "weird" generator local monotonicity property. But it's actually pretty useful, when you're building database indices, because it reduces the amount

More structure actually increases the chance for collisions. Because at that scale the chance of bit errors is dominating the equation. More rng protects against that.
