odigity it sorta depends a lot of the gem itself and the scope of the project. For instance, I think the prawn gem is fairly nice and I think that it would be best if people support it, if they have to do something related to ruby + pdf; but for many small gems, I feel that the differences to other existing gems that do something fairly similar, is very often just minor, often just a difference in style

<Ox0dea>
Rickmasta: You are *printing* the correct substrings, but the task was to collect them, yeah?
<hxegon>
Ox0dea: I mean he said he was converting nested mp3 files to m4a, so why not do the whole thing right?
<Rickmasta>
Nah. The tast was to find the number of unique substrings.
<Ox0dea>
hxegon: You're removing all the .m4a files right at the start...
chibs has quit [Ping timeout: 264 seconds]
<Ox0dea>
hxegon: Oh... well, yeah, that's one way to go about it, I guess.
<Rickmasta>
So I used an array to collect the substrings that I found and compare each new substring with the array to see if it was already counted.
<Ox0dea>
Rickmasta: Right, only that didn't go so well, and it's because the `temp` on Line 10 isn't always what you think it is.

temp is added to the collection right after the puts statement. I don't get why the array has empty strings and there aren't any in the puts statement.

<eam>
arne_: do you come from perl, perchance?
<arne_>
no, from c
<Ox0dea>
arne_: Simply put, `nil` is a "thing"; it is the single instance of the NilClass class. It has just as much right to be considered defined as any other Ruby value.
<eam>
in perl, accessing the key will auto-vivify the key
zenguy_pc has quit [Ping timeout: 264 seconds]

vivify?

ddv: Bring to life.
<eam>
but in ruby, {} is the same as a {} which has had a ["key"] dereferenced -- it does not change the datastructure
<ddv>
nice
<arne_>
i understnad that nil is a value, i just find it weird, that accessing non-defined variables throws exceptions, while accessing non-existent key in a array/hash doesn't

I am struggling with gem dependencies. I am trying to install a specific version of gem foo. when I do, it fails because something tries to install net-ssh 3.0.1, which requires ruby 2.0.0. yet 'gem dependency -r foo -v myversion' shows that it depends on a handful of things, valid versions of which are already installed.

how do I figure out what is trying to install net-ssh?
