<epitron>
RTFM? :D
<Todd>
whoa.. heh
<epitron>
you need to open port 60000
<epitron>
actually, you need a range of ports
<zendeavor>
or just pass a port in
<zendeavor>
unless you mean ec2
<epitron>
i mean mosh
<epitron>
read the docs
Lewix has quit [Remote host closed the connection]
<pontiki>
it says it cannot find mosh-server
<Todd>
udp eh? hmm
<Todd>
mosh looks cool
tanema has quit [Ping timeout: 246 seconds]
<pontiki>
the docs, such as they are, say 'mosh user@server' and that's it
<Todd>
yeah the docs say mosh will log you in via ssh and then start a connection on a udp port between 60000 and 61000
zmansiv has joined #ruby
<Todd>
that would only work if udp ports 60000-61000 are open to the machine you're connecting to or it's the dmz
<Todd>
it sounds as though it also requires that mosh be installed on the machine as well as an ssh server and that tcp/ip port 22 be open

You don't need to install mosh on your remote machine, you jsut need SSH.

have to go
lethjakm1 has quit [Ping timeout: 256 seconds]
<epitron>
xybre: incorrect!
<xybre>
epitron: since when?
<epitron>
since mosh works by using UDP
<xybre>
Mosh loads the mosh-server binary when you connect via SSH.
<epitron>
so at the very least you need that installed
<xybre>
What are you talking about?
<xybre>
Installing UDP?
<epitron>
how can it load the mosh-server binary if it's not installed?
ehc has joined #ruby
<xybre>
How does SFTP work?
<epitron>
SFTP runs over an ssh tunnel
<xybre>
Or SSH-COPY?
<epitron>
mosh uses ssh to launch mosh-server, which is a UDP server
<epitron>
running on port 6000*
<xybre>
Which is deploys on the remote server.

Hello, any ideal on how to encode some text as a valid PNG, as this > http://xcode.darkbyte.ru/ !? Trying for hours...
<xybre>
Maybe I misunderstood something in the documentation. I thought I didn't have mosh installed on my server and it worked though. Since I'm using mosh right now and all.
<Todd>
the mosh docs do speak about the mosh-server being in the path on the remote machine
<Todd>
and that if mosh-server is not in the path that you can specify the path to it when you run the mosh client
<Todd>
which leads me to believe that mosh-client in fact does not deploy mosh-server to the machine you're connecting to
<epitron>
the mosh author probably didn't want to create an ad-hoc multi-distro build system :)

hi guys! i've got a quick question re: refactoring. i'm repeating myself with some operations, i know i can refactor by creating a method that i can pass variables into. the only issue I have is that the method needs to operate on an instance of a class, so do i need to pass the class into the method or is there another way? i can post code if it needs to get to that stage.
<fwchld>
im not 100% on pass by reference or value and how ruby handles it...
freerobby1 has quit [Quit: Leaving.]

pass objects
Domon has quit [Read error: Connection reset by peer]
<pontiki>
or pass a block if you want to do it that way
<fwchld>
yeah, but if you instanciate the object, you pass that into the method is that ok?
ryandeussing has quit [Remote host closed the connection]
<pontiki>
an object is the instatiation of a class
<fwchld>
yeah i know
<pontiki>
well i don't understand your question, then
<apeiros>
classes are objects too
<fwchld>
lets step back a bit
<fwchld>
does ruby pass by reference or value?
<apeiros>
it's perfectly fine to pass classes as arguments. the question is whether it really makes sense.
<pontiki>
that was what i mean
buenob has quit [Remote host closed the connection]
<fwchld>
yeah i'm not passing the class
<pontiki>
it just generally makes no sense
<apeiros>
fwchld: depends on what level you look at. in the "ruby" level, it'd be by reference
goganchic has joined #ruby
buenob has joined #ruby

instead of module::class , just using class. I tried require, but it doesnt work

ganeshran: include that module

sanav: so you heard "dll" and want to learn about it?

MrZYX: yes !

you just can't make a DLL out of ruby code

I have a tty for my bluetooth speaker

there are little drivers and programs you can get which create extra virtual audio outputs on the system so you can plug inputs and outputs together to wire programs in to each other

a tty? :O

I wouldn't have expected bluetooth audio to go over serial :S

but if it uses a kmod you might be stuck

<shevy>
nah

what is RVM doing? it compiles into a specific prefix

we have a pretty strict rule these days that we do not compile anything on our servers anymore, if we need something custom, we have to package it up and deploy it via packages

you have to compile only once, no?

nhubbard, yup, fpm is pretty awesome for that, there are some really cool things emerging to help solve the issues
<Xeago>
shevy: no, they distribute environment requirements
viszu has joined #ruby

and based on those requirements they get what they need

in their case rubyxyz

then they don't fetch a ruby-binary or ruby-source
Naoe-Kanno has joined #ruby
<Xeago>
isntead they use a package that is prepared for that
<nhubbard>
shevy: yeah basically what emergion is saying….doing that for one server, sure, but what about when you have 100's or what about when you are using cloud and you need to automatically spin up new instances, now compiling ruby takes 5 minutes, so your configuration takes even longer to get your new server online

the things you can distinguish within methods are: which self, which method invoked, what args passed, block passed.

im trying to figure out how do take the correct element

where would i go to get the answer to this question?
<havenwood>
benjamin_: A really nice trick is to right-click and inspect the element in Chrome, then right click again on the code and "Copy XPath".
<benjamin_>
tried that
<havenwood>
benjamin_: Then the fallback is to learn XPath (or CSS selectors). :P

Hard for small projects, cause it often will take like 15min, and harder to setup payment than actually fix the problesm.

I guess IRC is a nice measure for very-small-problems. Easier to just do it for free. But for +1 hours I guess a wire is fine. Still I charge more for short jobs cause of the pain.

CSS selector would be another route that works in almost all cases, though XPath is ultimately more flexible.
