01:06 <FromGitter> <jwoertink> Is there a way to use the crystal-db without a block format?

01:07 <FromGitter> <jwoertink> or is it just common to open and close it every time you want to run a query?

01:09 <FromGitter> <jwoertink> It just feels weird to always do `DB.open() { |db| db.query "" }` all over the code

01:19 <FromGitter> <bcardiff> yes ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=58549298e7bdfe4e29640384]

01:20 <FromGitter> <bcardiff> @jwoertink `DB.open`is a connection pool actually. so I would recommend to create it only one.

01:21 <FromGitter> <jwoertink> Ah

01:21 <FromGitter> <jwoertink> Ok then that works

01:21 <FromGitter> <jwoertink> Thanks!

01:21 <FromGitter> <bcardiff> I published a couple of hours ago https://crystal-lang.org/docs/database/connection_pool.html

01:22 <FromGitter> <bcardiff> and https://crystal-lang.org/docs/database/index.html has a basic intro.

01:25 <FromGitter> <david50407> cool

17:40 <RX14> @asterite wow, on linux compile times for std_spec went from 1m7s to 12s in the bc+obj stage!

17:41 Ven has quit [Ping timeout: 250 seconds]

17:41 <RX14> and yep, I cleaned ~/.cache/crystal/

17:43 Ven has joined #crystal-lang

18:00 <RX14> 1:55.35 -> 48.012

18:00 <RX14> total time

18:02 <RX14> oh, and thats all_spec too, so it's even quicker to build the compiler!

18:05 <RX14> this is amazing

20:19 <FromGitter> <asterite> Yeah... the compiler did `fork` for each "compilation unit". In the compiler there were about 1200 units, so 1200 forks in linux seems to be really slow. On mac it's fast, I don't know why... since I develop on mac, it didn't affect me. But finally I decided linux devs should have some speedup too :-)

20:20 <FromGitter> <asterite> In the future we could further reduce times, when we implement incremental compilation at the semantic level

20:20 <FromGitter> <asterite> (but that might be a while from now)

20:22 sp4rrow has joined #crystal-lang

20:30 <RX14> @asterite forking only cores.times is the fastest on both platforms so i'm glad we made this improvement!

20:33 mgarciaisaia has joined #crystal-lang

20:34 <BlaXpirit> did u try cores+1 ?

20:34 <BlaXpirit> or cores*2

20:34 <BlaXpirit> things like these are often seen in thread pool implementations

20:34 <FromGitter> <asterite> I tried it, but it was slower. You can try it, just pass `--threads=16` for example

20:35 <BlaXpirit> ok thanks

20:35 <FromGitter> <asterite> Well, I actually tried it on mac... never on linux yet. So if in linux forking a bit more times gives better results, we should improve that too

20:40 <Yxhuvud> Is it cpu-, memory- or io-bound?

20:40 <RX14> should be CPU

22:47 <Papierkorb> What are the current options for OpenGL for 3D stuff?

22:48 <BlaXpirit> Papierkorb, http://blaxpirit.github.io/crsfml/tutorials/window/opengl.html

22:49 <Papierkorb> Thanks

22:49 <BlaXpirit> for opengl itself, i made something but not sure if it's best or if it even works still https://github.com/BlaXpirit/crystal-raw-gl

22:49 <Papierkorb> BlaXpirit: Have you planned something on making it easier to use crsfml?

22:49 <BlaXpirit> well i made it harder kinda but better

22:49 <BlaXpirit> no changes planned now
