00:34 <slfritchie> Sargun: I spent a little while last week fiddling with Promises. From my Erlanger POV, the stdlib docs really weren't helpful, and I couldn't find lots of good example uses in the unit tests. Ping me if you get stuck.

14:53 <Candle> http://playground.ponylang.org/?gist=a3a7c251350ca26613970196114f82ef generates 1,000,000 10 element arrays with each value in the range 0-9; the first element in the array is always 0; the 2nd element has a statistically odd distribution. elements 2-9 *look* like they have an even distribution. Is there something I'm doing wrong with seeding the generator, or in my usage of Rand.int(..)?

14:55 <SeanTAllen> Candle: are you using 0.20.0 or master?

14:55 <Candle> SeanTAllen: playground is running 0.20.0 [release].

14:55 <SeanTAllen> ok then yes, this is currently unreleased and will go out with the next version: https://github.com/ponylang/ponyc/pull/2321

15:09 <Candle> locally, 0.19.3 [release], generates some results that are even more skewed.

15:13 <SeanTAllen> nothing beyond that pull would possibly explain it to me candle.

15:27 <Candle> If you generate a random number between 0-255 and then use modulo 10 to convert it to 0-9 then it's less likely to be 6,7,8,9. (as 256-259 can't be generated in the initial byte). Looking at https://github.com/ponylang/ponyc/blob/master/packages/random/random.pony; something like that *may* be going on.

16:29 <slfritchie> Hi, Candle. There's a recently closed ticket about this, https://github.com/ponylang/ponyc/issues/2320. If you find that the PR that closed the ticket is insufficient, would you mind opening a new issue ticket at GitHub?

16:30 <slfritchie> Ah, right, Sean mentioned the PR earlier, sorry, PR 2321. I didn't do any statistical analysis beyond the first random number.

16:31 <slfritchie> Your findings are very useful information.

18:31 <Sargun> slfritchie: Are you writing Pony nowadays?

18:31 <slfritchie> Yup

18:32 <slfritchie> I joined Wallaroo Labs back in September.

18:34 <SeanTAllen> We are so very happy about that too

18:34 <SeanTAllen> Don't tell Scott though. We don't want him to get a big ego.

18:34 <Candle> slfritchie: Well, that gist contains a reasonable testcase for pRNGs!
