Just a few notes on a recent upgrade with a rails project that was fairly young thus did not have a lot of issues moving to rails 3.

problems upgrading devise in an rails 2 to rails 3 migration
I ran into some problems upgrading devise from 1.0.x to 1.3.x.
- to use passwords besides bcrypt you have to made 2 changes:
- in config/initializers/devise.rb
- config.encryptor = :sha1 (for devise 1.0.x compatibility)
- in User model (or whatever model calls devise)
- call devise with both :database_authenticatable and :encryptable
- you can tell you have issues with this if you see errors like BCrypt::Errors::InvalidHash or “invalid hash”
- in config/initializers/devise.rb
- browser validation prevents sign in with something other than email
- I create app/views/devise/sessions/new.html.erb from the devise version and changed email_field to text_field
- Can’t log in with “username” (some hidden JS blocking) – Devise | Google Groups
playing with ruby gui frameworks
Trying to figure out how easy it is to use ruby to write a desktop application. It would be nice to have something cross-platform. At the moment I’m playing with qt4, gtk2, and wxwidgets.
Firefox seems to load content in noscript tags when javascript is enabled
I can’t find any information about this, partially due to the badly named noscript extension, but it appears that firefox will load an image in a noscript block even when javascript is enabled. This is troubling for my use because I’ve put a static google map on an app for those that do not have javascript and wrapped it in a noscript to avoid loading it when it’s not needed. Now javascript users have to download the map twice, once static, once dynamic. Definitely a waste. Maybe this is fixed in firefox 4.
Some pc builds
These are some numbers for the cpu/mb/ram/video assuming all else will be equal. The AMD Phenom II X4 945 is available again. It’s a great CPU that allows for ECC RAM, if one is willing to spend 2x as much for ECC RAM these days. Intel Sandy Bridge system will be much quicker, though I am considering waiting for Z68 motherboards to become available as that is only a month or so away.

Comparing Piwik vs Open Web Analytics
Just some notes. Of course one could use both.

Need a new cell phone
My phone is experiencing a lot of problems, most noticeably that call quality has been abysmal. So I’m looking at new phones and perhaps a new carrier / plan.
I don’t like buying Intel CPU’s
I speculated earlier that I might buy a sandy bridge CPU and motherboard and that it would represent a break from 16 years of buying AMD. I have always bought at the low end of price where AMD has always offered superior competition. But I am not blind to how well sandy bridge systems perform and I am looking for more performance from my next system. I was strongly considering buying the i5-2500K and an H67 chipset motherboard. But today I learned about yet another limitation to this configuration (above the 2500K not supporting VT-d and TXT, though I’m sure no TXT is actually a loss) and that is that you cannot overclock it. So as usual Intel has a lineup which is complicated to make a choice because of all the various options in play. I much prefer AMD’s simple setup: all features on every chip and you just pick the speed and cache. Not to mention that I’d really prefer to buy ECC RAM which you can do on a consumer AMD motherboard but not on any consumer Intel board.
