You guys probably use some kind of program to talk and chat with friends and colleagues. So, tell me - which of the numerous programs available do you use?52

This moment when you worked 500h on a awesome class that will fix thousands of your problems.
And suddenly you find out that Qt already offers a class like that :c2 -

But at least we'll have fully sentient dildos armed with laser guns to mildly stimulate our mandatory attached cyber-clits, or alternatively annihilate thought criminals.
In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.
The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.
Whats left after filtering, is strictly the primes.
I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.
I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).
Well, imagine my surprise when I had zero false positives.
Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.
My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.
I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.
I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.
The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.
If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.16 -
bevy_reflect is literally the best thing since sliced bread
It allows you to do type and value reflection IN RUST!! A compiled language with dynamic runtime reflection of values. And with custom annotations on fields and structs too like
#[derive(Reflect)]
#[@SomeDataIWantToAttach {x: 20, y: 10} ]
struct MyComponent {
#[reflect(@MyCustomRangeAnnotation(0..10))]
pub num: u32,
}
It is nice. It is so nice1 -

I need an advise...
I am quite used to work in PHP. But I feel like it's getting older and older. Is there another comparable language? I'm thinking about Ruby or something...
What do you think? Do you have a more modern language in mind? Is it easy to use?21 -

Guys, I just need to know if I'm the one who's crazy.
I work at a fairly large bank. This bank has an Online Banking platform. Now, for reasons that deserve a rant of their own, I work on a self service account opening platform (in branch).
Now, my team is being tasked with adding features that will force customers to enroll in Online Banking and 2FA when opening accounts if they have not already done so.
The reason? There's low usage of the Online Banking solution.
My problem? I think this is a pointless waste of time.
Hear me out: All existing customers already have the ability to enroll with online banking, they can do it from there homes, in their underwear if they want, and they aren't doing it. Can anyone explain to me why we expect that customers who showed no interest in online banking before are going to be interested in using the application now?
You come in to branch to open an account, we stop the process to force you to enroll with internet banking(if you want to finish opening your account through the app), and then hope you'll use it now (despite the fact you could have enrolled at home all along)
We're duplicating the feature of an existing project and slowing down an unrelated process so we can hope you change your mind? Is this not a marketing problem? Do we not just need to sell the shit better? What am I not seeing? It's insane, we even took time to look at signing customers up for email addresses (in branch, while opening an account) if they didn't have one(because you need an email address for online banking). What really gets me is that everyone on my team is eating this shit up like it makes perfect sense. Like nobody else seems to think this is fucking stupid. I'm now resigned to implementing this bullshit. Am I the crazy one here? I realize I must be. Whatever I get paid anyway I guess. I raised my concerns repeatedly and I just kept getting the same stupid response. My job is done13
