Flash Builder 4 (aka Flex 4 aka "Gumbo") is released!

Lots of aka's (i know). Flex 4 SDK (open source) has been out for a while, or at least as a public beta. Now that Flash Builder 4 (the new IDE that replaces Flex Builder 3 -- note the product naming difference), there is a lot to be excited about.

A new skinning system that brings in the best of declarative graphics and fixes quirks with scale 9 and manual skinning of components. Supposedly everything is a lot more efficient and light weight. Flex 3 was pretty to look at, but a bit memory intensive. I don't have specifics on that yet, but all improvements are welcome to make it scalable for larger apps.

It is also designed for backward compatibility, so hopefully all our Flex3 apps compile nicely.

Looks like a great upgrade! If you are into ColdFusion/Railo as well, be sure to check out their bundle of Flash Builder 4 and ColdFusion Builder at a good price.

Here are some details:

Making Macbook Air with 128GB SSD usable with Bootcamp

I recently got a new Macbook Air 11" (the 2012 version) and loaded it with goodies like 8GB ram and 2GHz Core i7.  What I DIDN'T upgrade was the internal SSD.  My config came with 128GB SSD and I refused to pay $300+ to upgrade it to 256GB.  Yeah I know, some call me cheap, but SSds cost $75-$150 for 240GB, so adding another 128GB for $300 seemed way too steep for me.  I figured "ok, I'm going to make 128G work!"

Here is the story of how that went...

Installing python 3.4.x on OSX El Capitan

I love "brew" package manager, but sometimes being too progressive breaks things.  I have several python apps that I maintain that get deployed to AWS using Elastic Beanstalk.  AWS eb can deploy with python 2.7 or 3.4.  Any recent 'brew install python3" will get 3.5.1. #annoying

Dell XPS M1330 + Snow Leopard Hackintosh

I have been working with a Dell XPS M1330 laptop for a few years now.  It doesn't quite match up to the newest notebooks in terms of performance, but it certainly still has some life in it.  I had previously installed OSX 10.5.x on it as an experiment, and had moderate success.  I decided to revisit this idea again to install Snow Leopard (OSX 10.6) on the Dell M1330, and keep some notes for those of you brave enough to Hackintosh your own machine...
