Had a blast at the first ever Ruby conference in Singapore – RedDotRubyConf over the weekend. Awesome job by Andy and Jason and thanks a ton to all the guys from Pivotal Labs, Github, RubyX, Envy Labs, Pragmatic Programmers and of course the main reason were all there – Matz.
The amazing RVM was throwing a bit of a tantrum and rvm-prompt was simply returning
rvm
in new shells.
I tried re-installing but no dice.
So after bothering the nice people on IRC as well as on the rvm mailing list, the solution was in the rvm help. When in doubt and seeing odd behavour run
rvm reset
and lo and behold, ‘rvm-prompt’ now works again.
If you’re on the lookout for a new IDE for Rails in particular (or simply Ruby development in general) then have a look at RubyMine from JetBrains. It knocks the socks off NetBeans.
After having discovered RVM (Ruby enVironment Manager) and realizing how much easier it makes your life (application specific gemsets are pure genuis), I couldn’t get it to work on the desktop while it was fine on the laptop.
gem kept looking in /var/lib/gems/1.8 and it turns out there is quite a few places where GEM_PATH and GEM_HOME are being (or can be) set on your Linux box:
In my case it was the first 3 and after removing GEM_(PATH|HOME) assignments from those files, RVM started working.
Did my duty when it comes to Free software and reported a bug with the deluge torrent project.

Was struggling with an unbelievably annoying error, where PDF::Writer (or pdf-writer as it’s also called) simply refused to show special accented characters incl the Euro sign, but presented garbage instead. Turns out that as of pdf-writer 1.1.8, the following is the case:
a) No, it doesn’t accept utf-16, despite what it claims
b) Feeding it utf-8, will look fine for what can be mapped to 7bit ASCII
c) Feeding it Win-1252 seems to do the trick, although some people claim it’s also hit and miss.
In your class doing the PDF generation, add a method like this:
def to_pw(text = '')
return Iconv.conv('win-1252', 'utf-8', text)
end
And then call that to output all the text.
YMMV, but it worked for me.
