what was the answer, sorry if i lost that
Mr0rris0 has joined #ruby-lang
<bnagy>
like, I find it difficult to believe that you made it through 47 exercises of hardway without learning how require works
Mr0rris0 has quit [Excess Flood]
<jdecuirm>
like
<bnagy>
if you did then maybe you didn't do the additional work it suggests
Mr0rris0 has joined #ruby-lang
<jdecuirm>
about 47 exercises just worked directly in one folder
Mr0rris0 has quit [Excess Flood]
<jdecuirm>
then in 46 began to use a project skeleton
Mr0rris0 has joined #ruby-lang

just write a dummy skeleton and a nop test and learn how to require

what you could do though, is called log_changes when it's included, and define a class attribute/method on the original class that contains the options
<ljarvis>
which defaults to {}
<ljarvis>
we do something similar
<ljarvis>
so your remote_logger_options is pulled from the original class, not the other way around

let's say i have a string value that is in the format of a hash
<j2p2>
is there a safer way to turn it into a hash than eval?
<yorickpeterse>
j2p2: No, you have to parse it
<j2p2>
womp womp. thanks :)

well i'm parsing a response from one of our onsite sandboxes, so i *think* it should be pretty reliable
<j2p2>
I just didn't want to straight up eval it, just in case
<|jemc|>
I just mean it will only work for certain kinds of input - you're making a pretty big assumption here about the way your input string is formatted and what the keys are
momomomomo has quit [Quit: momomomomo]
<j2p2>
definitely true
<|jemc|>
an assumption you could remove by making sure the other end is using a proper JSON serializer
<|jemc|>
just something you want to consider if you don't want future maintainers of this system to be cursing your name

is there a faster way to do this?: i = [i.unpack("Q>")[0] + 1].pack("Q>")
centrx has quit [Quit: Shutting down, Please wait...]
<Xzyx987X>
I tested it, and it is roughly 20 times slower that incrementing an integer in ruby normally, which is sort of a problem for me...

<wallerdev>
you just need to add one and put it back in a string?
<Xzyx987X>
basically
enebo has quit [Quit: enebo]
<wallerdev>
maybe unpack multiple values from one string, not sure what format your input is
<wallerdev>
so you only call unpack once
<Xzyx987X>
I could manaually hack up a solution, but I was wondering if ruby provides any mechanism to do math on binary data
tunaCanBruh has joined #ruby-lang
<Xzyx987X>
in this particular case that wouldn't work, since I can only really use one value at a time, and the access to those values would be semi-random
<Xzyx987X>
or if a library exists that could help me
<lianj_>
Xzyx987X: no, you could try openssl::bn but that also puts into into a bignum first
roamingdog has quit [Remote host closed the connection]
<apeiros>
Xzyx987X: a tiny C ext could help
<apeiros>
should not be too difficult
<Xzyx987X>
I was thinking I'd just code a simple method to add to the string class that does a binary increment, and hopefully that will be fast enough
yfeldblum has joined #ruby-lang
<Xzyx987X>
I'd rather not mess around with C extensions until the design for what I'm programming is more finalized
<Xzyx987X>
then I may end up porting the whole thing to a C extension
<pipework>
You mean you don't prototype in assembly?
<apeiros>
uh, why are you asking about performance then?
<Xzyx987X>
well, I want the ruby version to still be usable fast, if for some reason someone couldn't use the C extension version
nathanstitt has quit [Quit: I growing sleepy]
<pipework>
Benchmark benchmark benchmark!
<apeiros>
Xzyx987X: and a single pack/unpack is your bottleneck?
<apeiros>
are you sure about that?
<Xzyx987X>
one of them at least
<Xzyx987X>
it adds like two seconds to the runtime of what I'm doing
<apeiros>
and it is not just slow, but indeed *too* slow?
tunaCanBruh has quit [Ping timeout: 264 seconds]
<Xzyx987X>
and my target is the whole thing should run in under one second
<lianj_>
Xzyx987X: can you show a an example where the two seconds come from?
<Xzyx987X>
the code I posted was the example...
__butch__ has quit [Quit: Leaving.]
<Xzyx987X>
I would need to post my whole code to give any kind of context...
lytol has quit [Remote host closed the connection]
<lianj_>
that doesn't show us how you get to i, maybe that can be done better
<apeiros>
for the isolated problem "increment an integer stored as binary data in a string by 1", I don't think you'll get a faster solution than what you just pasted
<lianj_>
^-
<apeiros>
so you either need to reframe the problem, or you'll probably be stuck
<Xzyx987X>
okay, well I need to store data in a string so that in all cases except for an overflow "string < string.increment" and string must be a fixed length
<Xzyx987X>
that is the most generalized desciption of the problem I could give
<apeiros>
and if we should help with reframing, then I second what lianj_ said - show more of your actual problem
<Xzyx987X>
the problem is I'm trying to generate a unique id for a piece of data that will sort in the correct order and be incrementable without being too slow
<pipework>
Yeah, let's jump to Z
<Xzyx987X>
I can't think of any other way to do it
<apeiros>
Xzyx987X: where comes incrementing into place?
<apeiros>
your sequence?
<Xzyx987X>
to generate the next id in the sequence
<apeiros>
if so: why do you store your sequence in binary and don't keep it in ruby and only pack. never unpack.
<Xzyx987X>
okay, so how do I get the next id?
<apeiros>
you increment your sequence by one.
<apeiros>
your sequence doesn't need to be in binary - or why would it?
dik_dak has joined #ruby-lang
<Xzyx987X>
except I don't know what the last id was without unpacking the data right?
<Xzyx987X>
how else would I know
<apeiros>
why?
<Xzyx987X>
because I can't cache it once it's strored
<apeiros>
Xzyx987X: you know that you're still leaving us guessing about *tons* of your system, right?
<apeiros>
why?
<apeiros>
why can't you cache it once it's stored?
<Xzyx987X>
right, which is why I just asked the simple version of the question in the first place...
<apeiros>
yes, which makes it an xy problem.
roamingdog has joined #ruby-lang
<apeiros>
and I fear the answer to your suggested solution is: no, there's no faster way (as I said previously)
<Xzyx987X>
because all I really wanted to know is if there was a better way to do what I specifically wanted to do than write it myself
<Xzyx987X>
if not, that's fine, but it would be difficult to explain why I choose to do things the way I did without showing you my whole project, so...
<apeiros>
that's your decision
<apeiros>
that may come off wrong. rephrased: ok :)
<lianj_>
so to add two seconds for unpack/pack yu have to do a lot of them. and there must be a way where you can more efficiently unpack i or keep it cached so you only have to pack again
<apeiros>
^ +1
stamina has quit [Ping timeout: 245 seconds]
<apeiros>
but they don't want to explain details, so…
setanta_ has quit [Quit: Leaving]
<Xzyx987X>
I actually think there would be some merit though, in writing a libary that alows you to do math on data held in a string by specifying the format
<Xzyx987X>
there are a lot of use cases you could really speed up
<Xzyx987X>
or just a more efficient version of unpack even, that only works on single values
<apeiros>
you rejected a C extension
<lianj_>
and how would it do that. convert it into ints and convert it back
<apeiros>
improvements to pack/unpack would probably be academic.
<Xzyx987X>
only for my current project in it's current state, not to solve the problem in the general case
<apeiros>
method call overhead is probably already larger than any overhead pack itself adds.
roamingdog has quit [Ping timeout: 252 seconds]
apt-get_ has joined #ruby-lang
<Xzyx987X>
well, actually, I also compared the speed to to_s/to_i incrementing
<Xzyx987X>
and it is also much slower than that
<Xzyx987X>
just not by as much
<Xzyx987X>
so there is significant room for optimization there
<apeiros>
without having seen those tests, I rather doubt that claim
<apeiros>
but hey
<Xzyx987X>
one sec...
<apeiros>
fork, optimize, PR
<apeiros>
all the better if you can improve ruby
<pipework>
So start by doing the dumb thing and then provide configurable options for optimizations one way or another, but guide it by benchmarking and profiling.
<pipework>
If you can speed up the whole thing entirely, put that in the baes.
bastilian has quit [Remote host closed the connection]
<lianj_>
Xzyx987X: didn't you have to convert it to hex or bits first for to_i to work
bastilian has joined #ruby-lang

I wasn't taking that into account in the test
<Xzyx987X>
but in practice you would, yes

Xzyx987X: use benchmark. you're measuring real time, not cpu time.
sarkyniin has quit [Ping timeout: 245 seconds]
<apeiros>
and which one was now slower than which one?
<apeiros>
also you compared Fixnum vs. Bignum
<apeiros>
you should probably compare same with same
matp has joined #ruby-lang
<Xzyx987X>
the pack/unpack speed was the slowest by far
<apeiros>
yes, as said, comparing apples and oranges
<Xzyx987X>
but anyway, no offense, but I really don't want to debate whether the problem needs to be solved
Iskarlar has joined #ruby-lang
<apeiros>
I'm not offended
<apeiros>
and I'm not sure what gave you that impression
<Xzyx987X>
I'm just going to write a binary string increment method and hopefully that will be fast enough
saltsa has quit [Ping timeout: 264 seconds]
* lianj_
doubts it
<apeiros>
I doubt it too that you'll be able to do something faster than unpack/pack in pure ruby which is also correct
<apeiros>
but as said before: go ahead. I'm curious.

roamingdog has joined #ruby-lang
centrx has quit [Quit: Shutting down, Please wait...]
<apeiros>
with the broken method, yours is 2x faster in the optimal case, about equal in the worst case. but given that the optimal case is 255x more likely than the worst case, that's quite a good result
