Any chance someone has a link for a crystal benchmark on sockets (outbound, not inbound) like a web crawler or concurrency in general? Been trying to find one to no avail thus far.
<Bofu2U>
and apologies for such a basic question, just having a hard time finding it heh

either my code is broken or amethyst is...

jhass: yeah, the builds are failing. but it seems like that's another reason
<xdougx>
jhass: Array(JSON::Type)? what should i do when i have it?
<xdougx>
jhass: this `?`
<jhass>
xdougx: that's |Nil
<xdougx>
jhass: but it is always treating like nil, i have no idea why is nil, the piece of code is this: http://carc.in/#/r/ktj but there isnt getting Array(JSON::Type)?

<BlaXpirit>
does it really copy the `i` into each thread or is this just a coincidence because the threads immediately run
<BlaXpirit>
(tried with `sleep` but `sleep` doesnt work

ok for assets and such maybe

already done it

is there an "elegant" way to read binary data from a slice/pointer and convert them to various types? I can't seem to find any other way apart from doing it manually.
<[spoiler]>
Oh, and is there a more compact way of creating a slice/pointer (I know I could've used `Array#to_unsafe` on the `barr`, I was testing something with slices, so that's a leftover)
<[spoiler]>
s/compact/pretty
<[spoiler]>
I tried `Slice(UInt8){...}` but that didn't work :(
<[spoiler]>
Oh and if the answer is "No, there ain't no pretty way to get that, data, you gotta do it manually, boy" then, would it be a good feature, so I can open a feature request and moan about it and/or add it myself?
<crystal-gh>
[crystal] asterite pushed 2 new commits to master: http://git.io/vWdX8
<crystal-gh>
crystal/master d707aac Ary Borenszweig: Dir.glob: make it work with multiple consecutive file separators
<crystal-gh>
crystal/master e4ee584 Ary Borenszweig: Fixed #1479: Make `crystal spec` only run files that end with `_spec.cr`
<[spoiler]>
Also, is there a way to create a String from a Pointer/Slice without copying the actual bytes?
<[spoiler]>
ooh dur, IO sems to have what I need, MemoryIO might be helpful.

plays around

jhass: is this possible def some; `cd /path/to/folder && rake some:taks`
<jhass>
should just work
<xdougx>
hope so :)
<BlaXpirit>
[spoiler], hi, do you still have questions?
<BlaXpirit>
if u have questions about pointers and stuff, feel free to ping me
<BlaXpirit>
i don't think MemoryIO is the thing
<[spoiler]>
BlaXpirit: Hi! I think I mostly figured stuff out now... 1. I didn't realise string were immutable and, 2. I didn't notice the #to_io/#from_io methods. Also, I discovered there's IO::ByteFormat stuff, and MemoryIO is helpful with testing! :D

I'm curious why is this done like this: http://git.io/vWbfj wouldn't using htons/htonl and ntohs/ntohl be better for performance? Also, aren't the 8-bit ones extra, since endianess only applies to byte order (unless they were added for the sake of consistency)?
<BlaXpirit>
[spoiler], why use lame C functions of limited availability for varying types
<BlaXpirit>
and sure, consistency
Sadin has joined #crystal-lang
<[spoiler]>
Hmm
<BlaXpirit>
i dont see how these would improve performance
<[spoiler]>
Well actually, it's a good point because you'll need to access them byte-by-byte anyway. I'd at least "write them backwards" (from highest to lowest index) rather than reverse and then write
<[spoiler]>
BlaXpirit: I mostly meant the use of #reverse!, because I think C's `_to__s` (can't be bothered to type them all the time) just fiddle the bytes
<[spoiler]>
oh well then
<BlaXpirit>
i'm a proponent of what you're saying
<BlaXpirit>
oh actually that bit fiddling implementation was bad
<BlaXpirit>
lol no wonder reverse is "faster"
<[spoiler]>
Hmm, it's still wise to use `unless SystemEndian == self` though. Also, not sure if there should be an `alias SystemEndian = LittleEndian`, since there *are* BE systems (rare, tho)
<BlaXpirit>
[spoiler], point is crystal is not supported on such platforms
<[spoiler]>
I think some hardware can be bi-endian, but I don't think there's an exclusively big-endian one anyway
<[spoiler]>
That's outright discrimination!
<[spoiler]>
#BEprocessorsmatter !
<BlaXpirit>
no, they really don't
<[spoiler]>
LOL
<BlaXpirit>
this SystemEndian alias is better, don't you understand, so that people dont have to assume little endian themselves
<BlaXpirit>
it can be changed if/when a big endian platform is supported
