brkkyk: Compiling parsed code into Ruby IR is a great speed win after first run. This could also be done for gems at install-time. This cuts out about a third of Ruby execution time. Then a JIT can make it faster to go from IR to machine code.
<havenwood>
brkkyk: See the yomikomu and bootsnap gems for examples of compiling Ruby files into YARV IR files so they don't have to be re-parsed to be re-run.

i feel like this might be a good beginning to an obfuscated ruby contest

<baweaver>
It's also fairly bad Ruby.
<hays_>
oh, please tell me all the reasons it is bad
<baweaver>
sarcasm?
<hays_>
no
<baweaver>
It's using a for loop, it's using a case statement for a two-prong branch, it assumes the format of the input to have formatted operators as symbols, it doesn't raise with an error message to clarify the intent of the error, and a few others.
<baweaver>
each or reduce would be more in line with common practice
<baweaver>
that, and it's not using varadic args
<baweaver>
Also send vs public_send
<hays_>
i considered reduce, but it seemed that it would reduce clarity. and to me, each isn't an idiom that implies that order is important.
<hays_>
i do not see a problem with a two pronged case statement, nor do I see a problem with using the symbols. I should raise a better error message--agreed. varadic args also might be a good idea
<baweaver>
RPN typically assumes a string input
<baweaver>
Normally one that hasn't been split
<baweaver>
Assuming symbols and numbers from the start is interesting
<baweaver>
each not implying order is an odd comment
duderonomy has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<hays_>
who says it has to be numbers
<hays_>
it can be any method.
<hays_>
that seems more flexible to me
<hays_>
I think that a reasonable implementation of each (maybe not in ruby) would ignore order and happen in parallel
<hays_>
whereas a for loop implies ordering
<baweaver>
That's... odd
<hays_>
If I tell you to chop each of these 5 vegetables, do you think you much chop them in the order i handed them to you?
<baweaver>
You're conflating quite a bit here
<baweaver>
The first of which is that there's a difference between each and for
<baweaver>
Then you're applying that ideal to Ruby syntax as it exists, implying that it _should_ go that direction for an ideal language, but not Ruby
<baweaver>
so you don't use that in Ruby
<baweaver>
feels hand wavy
<baweaver>
I mean sure, one could parallelize a Unit iterator in Haskell or Scala or what have you, and there are implementations of parallel each in Ruby
<hays_>
so, are you saying that there is no use case in ruby for a for loop?
<baweaver>
but as is Ruby iterates in order, even for Hashes which technically aren't supposed to do that.
<hays_>
since .each is equivalent?
<baweaver>
Essentially, yes. Idiomatically it's more commonly in use, and lends itself to blocks and functions that exist in other Enumerable methods
<baweaver>
as well as allows extension of the Enumerable module, so in ways no, they're not the same
<baweaver>
It depends on what you want to define as same
<hays_>
I am just surprised to hear the opinion that the use of for loops is bad ruby
<baweaver>
That's not remotely new
<hays_>
are you saying you've held this opinion for a while?
<baweaver>
Find _any_ style guide in common use for Ruby
<baweaver>
There are other more technical reasons as well including block level scoping
Inline has quit [Quit: Leaving]
<baweaver>
Implying further that it's solely my opinion is a bit off too
<baweaver>
This goes back to probably 1.8.7 or before.
<hays_>
we are just two people talking. I'm just trying to understand your ideas, which are probably coming from a place of deeper understanding of ruby
<baweaver>
The point I'm trying to make is this is not something unique to me, it's common across the Ruby ecosystem and across millions of Ruby projects
<hays_>
i wouldn't think code is bad if it clearly expresses what is happening, but it does appear that at least the rubocop style guide labels for loops as bad also
<baweaver>
It's bad if it goes against common idioms, causing newer programmers confusion.
<hays_>
someone who doesn't know what a for loop is
<hays_>
i wonder if we counted developers who didn't know what a for loop was and then counted developers who didn't know what .each does, which would be higher
<baweaver>
you keep doing that thing
<havenwood>
hays_: that ^ version is the same as yours, except it returns nil instead of raising
<baweaver>
setting up a strawman
<hays_>
havenwood: cool. each_with_object is fancy. yeah
<havenwood>
hays_: #reduce and #each_with_object are fun
<baweaver>
We're talking about Ruby
<havenwood>
hays_: or #with_object if you already have an Enumerator
<baweaver>
What other languages do or don't do is irrelevant to conversations on what is or is not common and idiomatic in Ruby
<hays_>
baweaver: there is a world where people must know many languages and not know them in great detail. I don't think that's necessarily a strawman. but I am not disagreeing with you, really. Except that I am not sure I would say that a for loop is bad. Maybe less idiomatic, sure
<havenwood>
hays_: we just don't use for loops in Ruby - honestly mostly for aesthetic reasons but they're also not optimized
<havenwood>
hays_: the idiomatic path is encouraged
<hays_>
havenwood: yeah, each_with_object is one of those things that pops up quite a bit
<havenwood>
hays_: you can always easily convert a for to an each, so it's kinda hand wavey to do
<havenwood>
hays_: it's handy!
<hays_>
your version really uses a lot of ruby-specific ideas
<baweaver>
I still prefer push to << for clarity
* havenwood
chants "shovel! shovel!"
<hays_>
some things I am actually reluctant to use in practice, maybe because of the people I work with, including myself, who have to switch between a lot of languages
<baweaver>
also because << does bad things to numbers :D
<hays_>
i tend to prefer ruby that could be trivially converted to .. say.. python without much deep though
<hays_>
t
<baweaver>
Then you're not writing Ruby
<havenwood>
hays_: I'd prefer it be easily converted to Elixir or Clojure without much deep thought. :-
<baweaver>
You _could_ make Ruby like Javascript too
<havenwood>
P
<baweaver>
Then you'd need polish notation instead of reverse for clojure
<havenwood>
haha
<hays_>
its the world I live in. in fact, we might be dumping ruby soon. for probably arbitrary reasons
<baweaver>
There are ways Ruby makes sense, and ways it doesn't
<baweaver>
Use the right tool for the job.
<havenwood>
hays_: We're using Ruby as much as ever.
<havenwood>
hays_: What're using instead?
<havenwood>
More than ever. Morever. Mever. Mer.
<baweaver>
We even managed to convince some yahoo over here to speak at RubyConf this year
<havenwood>
:-D
<hays_>
havenwood: well.. we backed into Ruby via Rails, and its been fine. but we're reconsidering rails, and some other things we're doing would indicate Python as a smart choice because of its rather strong set of libraries for .. well a lot o things
<hays_>
I personally don't think the problem is Rails. I think the problem is we don't have a strong enough team and its leading to bad implementations in Rails
<baweaver>
Mostly data science, ml, and things around it.
<baweaver>
You _really_ don't want to go more wild west with a loose team
<hays_>
baweaver: yep, but its also solid with web, comms, and other IT glue stuff
reber has joined #ruby
<hays_>
like I can pull down a iec 61850 implementation in python, but not in Ruby. its just so big
<baweaver>
If you have a bad team, nothing will save that.
<hays_>
It isn't going to be my call--software engineering is going to decide what to do with the Rails stuff
<hays_>
baweaver: yep
<baweaver>
Well, I say bad
<baweaver>
Inexperienced would be better
<hays_>
its just not a deep enough bench for the experience
<hays_>
im on the sidelines, but I am seeing just huge problems everytime I glance across it. last time I did, I found some huge resource leak with threads and sockets due to the way they were being created and managed. causing the app to crash the server
<hays_>
but we have one developer, and then a 'team in India'
<hays_>
all managed by the developer--a person who cannot manage a team
<hays_>
but this is wayyy off topic sorry
<hays_>
The stuff I'm working on is probably best suited to be Python. So I may have less occasion to use Ruby, which will make me a little sad, because I like Ruby
<hays_>
havenwood: small bug, your pops are backwards I think
<hays_>
[15, 3, :/] should yield 5

Hi there! I'm trying to make a ioctl system call via IO#ioctl from ruby and get some information from nvme block device. The code looks like this: https://dpaste.de/6hEz. Unfortunately, I run into errors like 'free(): Invalid pointer' (https://dpaste.de/Dsay). Despite this, I can successfully get the information about first three fields of the struct and then the behaviour is unpredictable. Could somebody explain what's wrong?

BTW, I'm also trying to avoid using FFI due to additional dependency. Thanks in advance!

I don't have access to the structure or header you're grabbing... it might be nice to isolate whether this is a problem with the pack/unpack side of things or the actual call to ioctl.
