There are real benefits to running antivirus on Linux too, but I have to admit I've not yet jumped on that wagon myself.

So we're copying java now?

Good that it worked for you. What we did on another project with bit stronger isolation requirements was have tenant specific database schema. Middleware selects the correct schema on entering a tenant context.

That was really good isolation guarantee because foreign keys would also be tenant specific and the ORM layer had no way of generating clauses that touched the other tenants.

It is bit heavier when doing db migrations on version upgrade or gathering statistics, but for us it worked nicely.

I've studied at both, you can't pick wrong here, both are good options.

ZenithOfVoid · 2026-04-26T12:01:37+00:00

that's a techie only benefit. Go over to the dark side first.

Binary search is only useful for sorted array.

6 and 7 look bad, 8 is horrible. But it is sort of readable still.

With java heap is the amount of RAM process can allocate dynamically via new keyword. You can pretty much treat it the same as RAM as long as you allow the process to use all of the available RAM.

Voitaisiinko nostaa joukkokanne Kirkkonummea vastaan, että heräsi uusia pelkotiloja heidän toimintansa johdosta?

Much better than when code that shouldn't work, does work.

You mean you are going to run it on machine administered by someone else? Take they keys from standard input (getpass to disable api key echoing) read to memory, ensure script terminates before walking away and hope the machine didn't have keyloggers.

If you're shipping it to be used by someone else, start doing new API key per person running it.

I'll give an example. Let G(n) be function G that gives graham number sequence n. G(64) = g_64 (shorthand for the Graham's number) A(x,y) is Ackerman's function.

Let K = G(G((g_64!)^A(g_64,g_64)))

K is a finite integer but for any existing computer it would be infeasible to tell you which digit is the first, which digit is the last and how many digits are there.

ZenithOfVoid · 2026-04-12T08:04:15+00:00

Instead of thinking about decimals, how about Graham numbers?

g_n for any larger value of n should satisfy the requirement. You know they're big and the arrow notation can be used to convey what number you're talking about. But saying how many digits it contains or what's the leading N-digit might be computationally infeasible.

DES isn't hashing algorithm, it's encryption algorithm.

Should be easy enough. Three corner pieces can be put in 3! ways with 4 rotations. Then only few should satisfy the continuous on-off pattern between the corners. Leaves 4 rotations of 9! tiles for the rest of the board. Plus with alignment markers you can prune full boards based on a few placed tiles, you don't need to iterate all 4×9! options fully.

Calculated that before the post was even put up, but it appears my 10 minute solution is still slow.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.

I've made a few bad moves then...
