I wanted to try out some of the new Ruby on Rails 2.0 features in Leopard, so I may as well blog my notes here for future reference. 1. Update Gems Use this if you haven't ugpraded your system to Rails 2.0 yet. sudo gem update --system # Update "gems" itself sudo gem install rails... Continue Reading →
Leopard UNIX Links

Character-Driven Branding
Steve Jobs once famously claimed that Apple's Executive Team spent "zero" time focused on branding; instead, they worry a lot about "who they are", and ensuring that their actions are consistent with that. While that may reflect the luxury Apple has as one of the world's best-known brands, it raises a crucial point. In today's... Continue Reading →
Poppendiecks on Lean Software Development
Thomas and Mary Poppendieck are to Lean Product Development (for Software) what Charles and Ray Eames are to design. LPD can be considered the project management aspect of Agile, to complement the software engineering practices of, e.g., Behavior-Driven Development. Some of my favorite essays from their website are: Train-Wreck Management The Challenges of Bringing Lean... Continue Reading →
ActiveResource: The RESTful standard
One of the coolest if under-hyped features of RESTful Ruby on Rails is ActiveResource. This allows you to treat any other RESTful Rails app as a database backend, providing an ActiveRecord like object model for abstracting that web service.Though changing slightly for Rails 2.0 (to use "/" instead of ";" as a parameter separator), this is becoming the de-facto standard for...

Rohit’s SynOA takes the “Sin” out of SOA
Many years ago, my buddy Rohit Khare introduced me to a guy named Roy Fielding, and tried to explain how this whole web services thing was going in completely the wrong direction. To be honest, I didn't understand what the big deal was, particularly since I wasn't really working with those technologies. Alas, neither did... Continue Reading →
It’s the System, Stupid
A brilliant essay by my new favorite website, on Lean Software Development.Which is more important - process or people? It helps if we trade in the overloaded word "process" and use "system."In the article "Managing a Living System, not a Ledger" H. Thomas Johnson says "Managers at Toyota believe that improving the system is the... Continue Reading →
LOP-ing Off Language-Oriented Programming
I've been fascinated by Domain-Specific Languages (DSLs) and metaprogramming for a while (particularly in Ruby), but just encountered the larger concept of Language-Oriented Programming (LOP). As someone who's been an OOP weenie since the late 1980's, I am intrigued by the question whether LOP and Language-Driven Development (LDD) will prove to be a similarly transformational...

Nested Data Parallelism in Haskell
[More unedited notes from OSCON] Nested Data Parallelism in Haskell by Simon Peyton-JonesAppeared in the mid-1990's, but not yet available in a mainstream language. cf. Flat data parallel (MPI, map/reduce, *C, OpenMP) -> chunking mechanism (not "N" threads) -> great for distributed memory systems (MPI) "do X to A[i]" X is sequential in NDP, X... Continue Reading →
Eben Moglen: Public Policy in the “Free” World
Yesterday Eben Moglen made headlines during the O'Reilly Radar at OSCON with a (somewhat) surprising attack on "Open Source" in general, and (more surprisingly) Tim O'Reilly in particular: Eben Moglen Wacks Tim O'ReillyEben Moglen Challenges Tim O'Reilly to Join the ConversationEben Moglen Berates Open SourceToday Eben had the stage to himself, to share his thoughts...
