Upgrade RVM and Ruby 1.9.2p290

I've been a little lazy and haven't updated my RVM installation (version 1.1.3, now 1.6.31) for a while and have been stuck on Ruby 1.9.2p0. This morning I upgraded, here's what I did:

$ rvm get head
$ rvm reload
$ rvm install 1.9.2-p290
$ rvm upgrade 1.9.2-p0 1.9.2-p290

Hmm… Got some errors, here's the output:

Upgrade complete!

Note that I opted to move over aliases, wrappers and completely remove my old ruby-1.9.2-p0.

Looking at the gemset.pristine.log I had the following errors for each gemset:

[2011-07-30 09:08:04] rvm gemset pristine # under ruby-1.9.2-p290@brandizzle
/Volumes/Data/Users/nicholas/.rvm/scripts/functions/environment: line 235: rvm: command not found

So for each gemset I executed the following:

rvm gemset pristine 

This seemed to work fine. Next, I checked out the errors in rvm.remove.log:

[2011-07-30 09:08:32] rvm remove ruby-1.9.2-p0 --archive --gems # under ruby-1.9.2-p0
/Volumes/Data/Users/nicholas/.rvm/scripts/functions/environment: line 235: rvm: command not found

Looks like the remove of my old 1.9.2 install failed, so I ran it manually:

rvm remove ruby-1.9.2-p0 --archive --gems 

Boom! Everything is updated and working.

"Building Web Apps with HTML5: Beyond the Buzzword" Follow-up

Just completed the Building Web Apps with HTML5: Beyond the Buzzword at RailsConf. The tutorial was well organized, had a quick pace and finished early, which is a good sign in my book. I'm not a fan of having a mad rush at the end to get everything finished. The tutorial itself was mostly self-directed with some discussion throughout so I'm not sure how much value was added by the instructor or doing it as a group.

Overall, well worth the time to get your feet wet with these emerging technologies. You can complete the tutorial yourself at: https://github.com/subelsky/html5tutorial. Thanks Mike Subelsky for your efforts.

One useful resource referenced throughout the tutorial is the website Dive into HTML5. Check it out.
