looks way more accurate than the tiobe ones

you see how people got annoyed when people went around suggesting everything got written in rust?
<RX14>
I don't want that kind of reputation as a community
<RX14>
also I think going up to another project and suggesting they rewrite everything *as an outsider* is never going to work
<FromGitter>
<Jens0512> I thought it was worth a try, and never heard of this rust-reputation
<RX14>
it's just going to get you ridiculed
<FromGitter>
<Jens0512> Yes i know
<RX14>
because it's unlikely unless you contribute that you know how much work it is to rewrite
<RX14>
and how well a language suits
<RX14>
"Homebrew is slow, that is because Ruby is slow, there are no arguments against this."
<RX14>
I wouldn't be so sure about that either
<FromGitter>
<straight-shoota> `at least a 100 times faster` is a bold statement for an application that's using IO operations as a central tool
<RX14>
that's doing LINEAR IO operations
<RX14>
it has to do x then y then z
<RX14>
it can't do them all at the same time
<RX14>
there's little that eventing gains you with such a workload
<RX14>
and as for how much time is spent waiting on IO and how much is spent in the ruby interpreter is something I would have benchmarked a lot before even considering a rewrite
<RX14>
because without that you have no idea why you're slow
<FromGitter>
<bararchy> Does MacOS always comes with Ruby installed ?
<FromGitter>
<Jens0512> Yes
<FromGitter>
<Jens0512> Ok. I am stupid. But I will not just go ahead and close the issue, I really think something at least has to be done about the speed.
<FromGitter>
<bararchy> Even most Linux dist don't have it pre-installed
<FromGitter>
<straight-shoota> and you would need to come up with a practical solution for including dynamic formulas
<FromGitter>
<Jens0512> That sounds easy enough
<FromGitter>
<straight-shoota> how?
<FromGitter>
<bararchy> Can you translate then to JSON format ?

<bararchy> Trying to call this from Crystal fails β β ``` code paste, see link``` β β It shows me that this isn't a function in the binded lib, an educated guess from my end tells me this is somekind of macro? is this why I can't call it?

<FromGitter>
<bararchy> I never actually developed in C\C++ so I'm sorry if this sounds like a stupid question
<FromGitter>
<yxhuvud> Memset is part of libc, no?
<FromGitter>
<yxhuvud> But it is inlined. Is it declared in a .h file?
<FromGitter>
<bararchy> yes
<FromGitter>
<bararchy> it's in an .h file
<RX14>
@bararchy inline functions are basically macros
<RX14>
well i'm sure you get the idea
<RX14>
they're directly included into the calling function by the C compiler
<RX14>
instead of being exported as symbols by the linker
<FromGitter>
<bararchy> I see, so to handle them in crystal I should just see what it actually do and copy the logic , as there is now way to call it from Crystal
<FromGitter>
<bararchy> Right?
<RX14>
yes
<FromGitter>

<faustinoaq> I saw RubyVMs written in C, Java, Javascript (Opal), LLVM (rubinius), others like Trufle, etc, etc β β Should be possible to writte a RubyVM in crystal as well? π
<FromGitter>
<bew> Yes, but why ? ΛΛ
<FromGitter>
<faustinoaq> > Does MacOS always comes with Ruby installed ? β > Even most Linux dist don't have it pre-installed β β @bararchy Its depends, In Manjaro by example ruby come installed by default, along side with other lenguages like perl, python, lua, tcl, mono, gcc, java and shell. (Yes, I know, so many languages installed by default), I think is mainly because program dependencies, Manjaro comes with a bunch of
<FromGitter>
<faustinoaq> There are so many distros as well
<FromGitter>
<faustinoaq> The thing why I like Manjaro so much is because is rolling release and is easy to maintain, I have almost 2 years using it without reinstalling, just usual updates, always running latest stable software π

<FromGitter>
<bew> hum, the pull parser is not documented in the API doc.. For you usecase, either you do aparser, or a converter. For example if you only want a String, but add some parsing on it, you can use a converter.
<FromGitter>
<faustinoaq> > yes Arch is great... though I haven't used it for a while. β β @straight-shoota @bew Yeah, Arch is awesome, although is a pretty different story on a production server π β β I always use debian, ubuntu or centos on servers, sometimes I try alpine with docker [https://gitter.im/crystal-lang/crystal?at=5aa2ecdee4ff28713a1392b4]

<elorest> I love pacman and aur but my installations do seem to break a lot more than when I'm using ubuntu desktop.

<elorest> @bararchy I was under the impression that HCI was deprecated...
<FromGitter>
<bararchy> well, they want to, they want all functionality to move over to DBUS, the thing is DBUS does not have full support for GATT and other stuff, (experimental state)
<FromGitter>
<bararchy> also, DBUS is annoying
<FromGitter>
<bararchy> I personally hate XML
<FromGitter>
<bararchy> hahah
<FromGitter>
<CImrie> Don't anything more to input other than eugh... xml.
<FromGitter>
<bararchy> ^ this XD
<RX14>
indeed
<FromGitter>
<bararchy> if DBUS would have supported JSON i might have more love toword it, but it also screws up working with binery data, and forces you to follow Python, so binding the DBUS-Bluez in Crystal was like β β Crystal -> XML -> Python -> C > Python > XML -> Crystal
<FromGitter>
<bararchy> so I figured, lets bind directly to C
<FromGitter>
<bararchy> and be done with this insanity
<FromGitter>
<bew> Note: I'm working on pure dbus for crystal, I already have the authentication working, I'm working on the protocol for messages r8t now
<FromGitter>
<bararchy> RX14, it seems DBUS is using `python` or `python like` languge as it's "DSL" or whatnot, I actually had a need to send it `__import__('dbus').Boolean(0, variant_level=1)` for reasons unkwon
<FromGitter>
<pr-yemibedu> that sounds so nice without python

<greenbigfrog> if I want a method to once compare if sth is bigger and the next time if it's smaller, what's the best way to pass in a `<` or `>`?

you sure you don't want <=>
<RX14>
also usually a block with a and b and then you use a > b or a < b is the most flexible
<RX14>
but otherwise just use an enum or symbols or sth

Disrecollection has joined #crystal-lang
<FromGitter>
<CImrie> @bew "Generic Attribute Profile" - basically a specification to say that BLE devices use things called services and each service has characteristics. β You can 'discover' services and characteristics, and listen for characteristic notifications etc. So if you subscribed to a button-press characteristic for example, you'd be notified when the button was pressed on the peripheral. Though AFAIK which
<FromGitter>
... characteristic does that is up to the manufacturer, even though there are common ones in use for compatibility.
