In my previous list of WP7 user requests, I piled all of my user hopes and dreams for my new WP7 phone (delivery date: who the hell knows) onto the universe as a way to make good things happen. And all that’s fine, but I’m not just a user; like most of my readers, I’m also a developer and have a need to control my phone with code. I have a long list of applications I want to write and an even longer list of applications I want other developers to write for me.

My dear friend Craig Andera posted an implementation of a function that descends into a directory in a “lazy” manner, i.e. you get the first descendant back right away and not after all descendants have been calculated. His implementation was in Clojure, a Lisp variant that runs on the Java VM:

(import [java.io File])

(defn dir-descendants [dir]
  (let [children (.listFiles (File. dir))]
    (lazy-cat
     (map (memfn getPath) (filter (memfn isFile) children))
     (mapcat dir-descendants
      (map (memfn getPath) (filter (memfn isDirectory) children))))))

When I first moved from the combination of a dumb phone and a separate music player, I had modest requirements: phone calls, MP3 playback, calendar notifications, contact management, email, camera and solitaire. Even asking for only these seven things, my first smart phone was as life changing as my first laptop. I could do a great deal of my work while out and about, allowing me to have a much more productive work/personal life balance.

Here’s how the Deep Fried guys describe episode 45: “At PDC 2009, ‘Oslo’ was renamed to SQL Modeling and it left a lot of developers scratching their heads. What better way to sort it all out than to talk with someone deep into the stack. We sat down with Lars Corneliussen to see how this is all going to turn out and it what it means for developers. Definitely an interesting show as it paints a different picture about where things are going with ‘M’, ‘M’ Grammar, SQL modeling, Entity Framework, Quadrant and so on.” Check it out!

When I was but a wee lad, I learned that when it came to my computer, I was often going to be waiting on something, whether it was the CPU, the IO or the memory. Now that I’m all grown up and spending a great deal of time on handheld mobile devices, I’ve discovered a whole new thing I’m waiting on: charging the battery.

We are currently preparing a release of the SQL Server Modeling November 2009 CTP that will install and operate with Visual Studio Release Candidate. We expect to make this release available the first week of March and will make an announcement here at that time.

We are also planning for another release of the November CTP that matches the final Visual Studio product (RTM) when that product becomes generally available.
