i don't need to do that i needed an equivalent… i just did each_with_index and tested if index == count to avoid the last append
<Asher>
decided that was better than all the extra arrays and flattening and compating
<seanstickle>
Loops, yuck
<whitequark>
seanstickle: each* aren't loops
<seanstickle>
It is when you start using index to do stuff
<Asher>
better than creating an extra object and then chopping it off, no?
<whitequark>
I agree
<imperator>
Asher, do the numbers have to stay numbers? or can they be stringified?
<Asher>
they're actually objects in teh use case
<Asher>
instances of my own classes, that is
<imperator>
ok
<duckinator>
well then, it would seem my issue before where $DEBUG=true/--debug caused threads to behave noticeably different was system-specific o.O
<seanstickle>
Well, or you could just do [1,2,3].flat_map { |x| [x, "-"] }[0...-1]
<seanstickle>
Which is the more obvious route

Ive made a side project, 2 or 3 months ago. Let it totally unmaintened, to my surprise, when I was dumping the db to move it to another server today I've found out 8k registerd users, 2k notes! 10gb of sessions. No bots, looks legit emails. The app is X-rated, that explains a lot but wow.. I'm in shock.
<ruskie>
lol
<nofxx>
Anyway, why I came here: was thinking about hiring someone to help, but after a second tough, this can me rentable in any city, If I could find a partner, with good ruby skills
<nofxx>
thinking about investing in it
<nofxx>
but got to finish another project in the upcoming 2,3 months*
<drbrain>
nofxx: I was shocked to see someone using net-http-persistent to near 1 million HTTP requests on a single connection
<nofxx>
drbrain: build something, dont ad anywhere, make the layout totally f* up after you switched from pg to mongoid couple of months ago
<nofxx>
sum up a register form.... you can't get 8k users if it's not porn

I wish I could figure out how I'm messing up symmetric encryption
<erikh>
are you not carrying over the IV?
<drbrain>
I'm carrying over the IV
<erikh>
I've made that mistake
<drbrain>
the cipher, key and IV are all identical
<drbrain>
I'm getting "wrong final block length"
segy has joined #ruby-lang
<erikh>
hrm.
<erikh>
yeah, I'm pretty green with this shit. probably shouldn't have said anything.
<erikh>
and the last time I touched it 3DES was the algorithm everyone wanted to use
<drbrain>
I'm using DES-CBC and encrypt to 184 bytes, which is a multiple of the 8 byte block size of DES
<drbrain>
it's for growl
<erikh>
growl uses DES?
takaokouji has joined #ruby-lang
<drbrain>
it supports DES (why?), 3DES and AES
<erikh>
heh
<erikh>
yeah, that's where my head was going.
<drbrain>
… and the documentation comes from the windows growl people reading the growl source code
<erikh>
lovely
<drbrain>
… and I've found a handful of bugs in growl 1.3.1
<erikh>
isn't growl going the way of hte dodo with mountain lion anyhow?
<drbrain>
no idea
<erikh>
yeah, they're implementing a notification center like from ios
<erikh>
... anyhow, best of luck
<drbrain>
GNTP is for remote notifications, which is something Notification Center may not support (network-wise)
<drbrain>
so, growl may still stick around
<drbrain>
I imagine growl will still be used for people who want notifications to "look cool"
<erikh>
fair
<erikh>
I need to grab a project and stick with it
<erikh>
too much shuffling around lately.
<drbrain>
well, other than it costs $
<drbrain>
I should go to sleep, I'm not going to figure this out tonight
<erikh>
good idea.

then you're having the same issues as they are?

time

i have enough of my own native code to maintain, without having to work on other peoples libraries
<Defusal>
well i often hit edge cases, i guess most people only use the common parts of the framework
<Defusal>
and only in common ways
<Defusal>
i mean, i saw a thread on a mailing list from i think 2001, which said the next version of EM would be patched with inotify and a similar one speaking about the netlink code from the God gem
<Defusal>
yet nothing has been done, over 10 years later...

so i end up having to implement my own stuff and have the reactor watch the IO descriptors

it colours output and does simple constant and method completion too, which is quite useful
<Defusal>
yeah i was told about pry remote after i did that

i'll probably replace it with that eventually

since pry will be more feature complete

andrewvos, thanks for reminding me to take my medication :)
<rking>
Defusal: Oh? Got a blood test coming up you're trying to pass? Good strategy.
<Defusal>
nah, actual medication :P
<rking>
Nah I was saying it as in psych meds that they make you take. Too obscure.
<Defusal>
oh, haha
<Defusal>
this stuff is equal to a very strong cup of coffee
<any-key>
just drink coffee then, it's cheaper
<Defusal>
since i don't have time to sleep much a the moment, countering fatigue and increasing cognition is important
kenips has joined #ruby-lang
<Defusal>
coffee has a long half life and decreases your quality of sleep even 20 hours after having a cup
<any-key>
sign me up!
<Defusal>
i've had to stop all coffee, with the amount of sleep i have time for, i cant afford for the quality of it to be any less than is possible
<any-key>
but taking a stimulant is different?
<Defusal>
no, a decent stimulant would be a lot worse, which is why i can't take any of those either :/
<any-key>
stimulants beyond a cup of coffee really suck to take, I'll leave it at that
<Defusal>
indeed
<Defusal>
a cup of coffee alone sucks a lot more than most people are aware of
<any-key>
dunno about that
<Defusal>
most people in todays society are sleep deprived, but mask it with coffee

Wait. 0 == false.object_id and 2 == true.object_id. What is 1?
<rking>
maybe.object_id ?
<any-key>
I won't argue with that, but in all honesty the act of drinking a nice warm beverage in the morning is very nice
<outoftime>
rking: 0
<Defusal>
any-key, you don't have to convince me of that :P
<Defusal>
its been very hard to stop myself wanting a cup in the morning
<Defusal>
the best i can do is a cup of green tea
<telemachus>
judofyr: re: bash scripts have you looked at thoughtbot's laptop project?
<outoftime>
rking: a fixnum's object_id is (num * 2 + 1)
<tobiasvl>
<Defusal> most people in todays society are sleep deprived, but mask it with coffee
<rking>
outoftime: Aha, yep. How would I reverse this? Like look up an object by Id?
<tobiasvl>
Defusal: or perhaps s,sleep deprived,caffeine addicted,
<any-key>
Defusal: tea is supposedly better; it works longer and the dropoff is less extreme
<Defusal>
yup
<telemachus>
I just saw it today after reading about rails.app. So far it's Apple only and assumes a lot (zsh, rvm), but I like the idea of it a lot.
<outoftime>
rking: there's a way to do that, but I require you justify your need to : )
<tobiasvl>
that is, caffeine withdrawal makes you more tired
<Defusal>
i've used green tea for about a year now
<Defusal>
whenever i go back to coffee, even just one cup, i get screwed over a little later
<any-key>
rking: yeah, you really shouldn't ever need to do that
<rking>
outoftime: Only exploring. I find this num*2+1 thing interesting.
<any-key>
Defusal: maybe you shouldn't drink mean coffee and drink nice coffee instead
<mistym>
Tea reminds me, I need to go make some silver needle :9 Guess low-caffeine's not that good for first thing in the morning but it's so tasty.
<Defusal>
any-key, i've tried weak instant stuff, as well as imported filter coffee
<outoftime>
rking: just don't do it in real code : )
<Defusal>
but with my sleep schedule, i can't afford the loss in quality of sleep
<any-key>
I was mostly just joking :P
<Defusal>
coffees half life is way too long :P
<rking>
outoftime: Coolness. The leading underscore means it's for Enterprise Application use, right?
<any-key>
outoftime: should've waited for a reason
<outoftime>
any-key: look up : )
<any-key>
ah whoops
<outoftime>
rking: the leading underscore means "Don't use this, ever."
<Defusal>
but hey, i would definitely be using coffee if i had time to get a decent amount of sleep per day
<Defusal>
i sure miss it
<rking>
outoftime: I was kidding. I shouldn't kid.

<rking>
outoftime: Thanks for lookin' out. =)
<judofyr>
rking: also, notice how all symbols have even object ids :)
<any-key>
everything is an object
<any-key>
ruby has a reputation for objectifying things
<any-key>
it can be quite rude
<rking>
judofyr: I'm noticing that strings have -INT ones, but they only exist as id's once you call .object_id on them.
jxie has joined #ruby-lang
<telemachus>
judofyr: Yup. I would like to see it support bash at least though. They're already thinking of that (and of maybe switching rvm for rbenv). Either way, it would be easy to fork and tweak to slightly other preferences.
<judofyr>
rking: hm? only exist?
<rking>
Interesting. Symbols are not that way. If you start a new irb and do ObjectSpace._id2ref(118578), sure enough it gives you :b.
<outoftime>
rking: symbols are interned, which means any given symbol value is always the same object
<outoftime>
rking: each time you type a string literal, it creates a new object
<rking>
judofyr: Ok, what I did was: "a".object_id, and it gave me like -12341234. Then ObjectSpace._id2ref(-12341234) returned "a". But when I restarted and tried the _id2ref() again, it didn't work.
<injekt>
and no syntax error
<judofyr>
well, "rking".object_id == "rking.object_id" is false though
<injekt>
it would still be false
<injekt>
too slow injekt, dammit judofyr
<outoftime>
injekt: right, actually, my code is entirely correct : )
<outoftime>
just not especially useful.
<judofyr>
rking: ah, right. that's because the object doesn't exist in a new Ruby instance
<RickHull>
perfectly cromulent

pygmael has joined #ruby-lang
<judofyr>
I can't* revive you
<rking>
judofyr: OK.. so I'm seeing something kind of weird. :b.object_id works across invocations, but not :asdasdfdsafd.
<rking>
Looks like perhaps all the single-letter symbols are already instantiated.
<judofyr>
rking: really? is consistent here: ruby -e'p :asdasdfdsafd.object_id'
<rking>
judofyr: Now try changing that to :jklkjkl and see what it prints.
<judofyr>
rking: but that ID will change if anything else is allocated earlier
<judofyr>
rking: sure. it's just a counter. first object allocated gets that id.
<judofyr>
well, at least for symbols
<judofyr>
they are simple
<judofyr>
other objects might cause other stuff to allocate too, and then it's not consistent anymore
casaram has joined #ruby-lang

rking: know anything about pointers (in C)?
telemachus_ has joined #ruby-lang
<rking>
judofyr: Definitely.
<judofyr>
rking: the object_id is just a pointer :)
<judofyr>
rking: which points to the heap.
<judofyr>
well, except for fixnums
<judofyr>
they are embedded in the object_id
<judofyr>
and nil, true, false
<rking>
judofyr: It's like a pointer or it's literally a machine-code address?
<judofyr>
rking: literally a machine-code address
<rking>
BTW, for a good time: pick some n then: 0.upto(n) do |e| begin x = ObjectSpace._id2ref(e); p x unless Fixnum == x.class; rescue; end; end
<judofyr>
rking: you can just skip all odd numbers; they are guaranteed to be fixnums anyway

wonders now if ssh sorts out STDOUT/STDERR.
<kalleth>
so net/ssh to execute the commands/scripts, and write my own sinatra wrapper around that to use net/ssh and report the results

just grab the results with net/ssh
