12:23 <FromGitter> <rishavs> Can someone tell me an overview about how the crystal arrays are implemented? They seem to be classes and I am not sure how this is done.

13:28 <FromGitter> <oprypin:matrix.org> @rishavs: it contains a member that is a pointer to a "raw" memory region that is immediately populated and has a constant size and doesn't need to be even anywhere near the actual object in memory. ⏎ it is also possible to reallocate the raw memory on request (when array needs to grow), which is usually just making a new allocation and copying all data to it

13:29 <FromGitter> <oprypin:matrix.org> that is GC.malloc if i remember correctly. it's probably the part that you're missing. without this low-level operation this may indeed seem impossible

15:49 <FromGitter> <rishavs> Thanks!

17:47 <FromGitter> <rishavs> I am trying to do a very simple benchmark between the iteration time of arrays vs that of hashes, but my benchmark report is not showing up; ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=61d4881cd41a5853f933ae28]

17:47 <FromGitter> <Blacksmoke16> prob just doesnt work on windows?

17:47 <FromGitter> <rishavs> o.0

17:48 <FromGitter> <Blacksmoke16> remember windows support isn't 100%

17:48 <FromGitter> <rishavs> Thanks ! Good catch. I am indeed trying it on windows. ^_^ ⏎ Back to wsl I go...

17:49 <FromGitter> <Blacksmoke16> yea id try it there and see if that fixes it

17:54 <FromGitter> <rishavs> Thanks! that did the trick. ⏎ Btw if anyone is interested in hearing, array iteration seems to be between 1.5x to 3x times faster than hash iteration

17:55 <FromGitter> <Blacksmoke16> what are the numbers tho? 300 trillion is more than 100 trillion but both are totally sufficient :P

17:56 <FromGitter> <rishavs> i tried with 10, 1000, 10k and 1M entries in both

17:56 <FromGitter> <Blacksmoke16> sorry, mean the number of ips

17:57 <FromGitter> <rishavs> oh, went with the defaults

17:57 <FromGitter> <Blacksmoke16> 😅 no i mean the results of the benchmark

17:57 <FromGitter> <Blacksmoke16> like the thing it prints

17:58 <FromGitter> <rishavs> Here's one example ⏎ ⏎ `` ⏎ hashy 98.53k ( 10.15µs) (±14.40%) 0.0B/op 1.57× slower ⏎ arry 154.32k ( 6.48µs) (±20.62%) 0.0B/op fastest ... [https://gitter.im/crystal-lang/crystal?at=61d48abb742c3d4b217ec376]

18:00 <FromGitter> <Blacksmoke16> 👍

22:31 <FromGitter> <plambert> I'm looking for someone to do a contract programming job in crystal; if anyone knows of a person looking for a relatively small job that'd contribute to a popular open source crystal library (all work will be contributed), let me know!

22:38 <FromGitter> <plambert> And if anyone knows a better place to ask this question, don't hesitate to tell me!

22:39 <FromGitter> <christopherzimmerman> What’s the library?

22:43 <FromGitter> <plambert> crystal-sqlite

22:43 <FromGitter> <plambert> *crystal-sqlite3

22:44 <FromGitter> <plambert> I'd like to add the ability to define custom functions (aggregate and ... whatever not-aggregate are called), and virtual table implementations. If it's not hard, throw in support for a virtual pager, but custom functions and virtual tables are what I need most.

22:46 <FromGitter> <jwaldrip:matrix.org> https://github.com/crystal-lang/crystal-sqlite3 >/

22:46 <FromGitter> <plambert> Yes.

22:46 <FromGitter> <christopherzimmerman> Are there issues created requesting those? If those are fleshed out I’d be happy to take a look at them, don’t need a contract.

22:46 <FromGitter> <plambert> Thanks! I'd be happy to open the issues.
