Lol, I think most of that randomness is somewhere in the test directories.

My thoughts exactly. Randomness has a place in tests, but not in unit tests.

Hmmm but if you change the distribution, this won't be deterministic anymore unless the randomness only applies to new users entering the test setup.

Where you say random I think you mean systematic.

r3bl | karma 5648 | avg karma 4.03 · | 2015-09-02 14:25:15+00:00

Well, it's totally random alright.

taneq | karma 28647 | avg karma 2.93 · | 2017-06-19 14:03:08+00:00

Not sure if I'd describe them as random, but yeah.

dpflan | karma 9608 | avg karma 4.04 · | 2023-10-20 11:16:29

Yes, randomness!

Yet every run still has many thousands of RNG invocations for that particular metric. To be off by a few percent, safe to say that RNG would fail any randomness test.

I mean, unless you know all the variables in the feature scope it is pretty much random...

dang | karma 18142 | avg karma 0.25 · | 2023-03-15 13:32:22

It's just randomness.

le-mark | karma 2875 | avg karma 3.28 · | 2022-08-20 12:31:15

Hmm this made me chuckle, is that not equivalent to a test for randomness, which is very very hard indeed?

Groxx | karma 17784 | avg karma 2.5 · | 2010-03-07 20:25:35+00:00

Except it's "stuff I queried", which is pretty random. Or at least not predictable before being tried, which is nearly as good.

Besides, geeks like to shrink things. I wouldn't have been surprised if it used "rand(YC application videos)", to save a character.

Well, it's deterministic, because the program is deterministic, but it certainly does look random.

Randomness

Traubenfuchs | karma 3154 | avg karma 1.84 · | 2023-07-19 04:29:55

That is very much not random, but generally enough for 99% of all use cases.

snikeris | karma 1159 | avg karma 2.85 · | 2016-06-06 17:14:46

More random, I'd say.

Rezo | karma 1661 | avg karma 8.14 · | 2016-04-03 12:24:20

Pretty sure those are random too.

kwillets | karma 568 | avg karma 1.91 · | 2022-06-21 12:10:28

random was what came to my mind after your first sentence. It could really use a deterministic test harness for the different layers.

7ewis | karma 863 | avg karma 3.0 · | 2017-07-19 21:56:31+00:00

That definitely is quite... random!

sjg007 | karma 6164 | avg karma 0.98 · | 2016-07-12 02:05:46+00:00

Sometimes it is just random.
