Dragos Manolescu's (work) blog

You're looking at dead content. I am no longer updating this blog and have relocated to my personal web site . See you there ;)

A few weeks ago I showed how to represent computations involving geo locations or accelerometer readings as queries over RxLINQ event streams (i.e., IObservable collections). In both instances the event source was one of the sensors that is on board of...

  My previous  blog posts on WP7 Code covered the GeoLocation API, a surface area that provides access to the phone’s location based on signals picked up by one of its radios. However location alone is probably not sufficient for mobile applications...

  Visual Studio and the Windows Phone Developer Tools make building software for the Windows Phone similar to building desktop or browser applications. However, beyond these similarities crafting a phone application differs fundamentally from building...

  Besides providing geographical coordinates , computing distances , and making reverse geocoding service requests Windows Phone 7 can also signal when it is moved outside of a perimeter. The buzzword for this scenario is Geofencing , and this post...

  My previous blog posts showed how to obtain location as an event stream from the Windows Phone 7 GeoLocation API, and how to translate lat/long position readings into distances. Here I show how to build an application that combines data from the...

  In my previous post I showed the most interesting code fragments for a location-aware Windows Phone 7 application. The code generates an event stream corresponding to location readings from the phone’s location subsystem. However, there are many...

  I’m kicking off a series of blog posts focused on writing Windows Phone 7 code with one of the APIs that will probably attract many developers interested in getting their feet wet: GeoLocation . Building this code requires: The Windows Phone Developer...

It’s been an embarrassingly long time since my last post on this blog. Several cool projects in the Windows Phone 7 team kept me busy. Now that we shipped the bits I’d like to revive this blog with snippets on writing Windows Phone 7 code. Stay tuned...

Earlier today we announced releasing the runtime code of the Web Sandbox available under the Open Source Apache License 2.0 . The announcement has already been picked up by the blogosphere . Should you head over to the site check out the Web Slices samples...

By now this is already old news, but here it goes. Last week Live Labs released two cool projects: On Wednesday 12/10, Thumbtack . I've seen demos of this project since it had a different name, and have discussed it with some of the folks who came up...

Earlier today we rolled out an updated version of Live Labs Web Sandbox CTP, a technology for securing Web 2.0 through virtualization. This update incorporates new features on several fronts (more on that elsewhere). In this post I'd like to call out...

Earlier today we launched a technology preview for Web Sandbox , a project aimed at securing Web 2.0. The Sandbox applies techniques from programming languages to inject an interception layer that in effect virtualizes the execution of untrusted code...

A project I've been involved with for the first part of the year is now live, just in time for the election season. My fingerprints are on the underlying platform called Social Streams. One of my favorite features is the ability to navigate across several...

My article Volta: Developing Distributed Applications by Recompiling (co-authored with Brian Beckman and Benjamin Livshits ) is now available in the Software Development Tools issue of IEEE Software (September/October 2008). Here's the abstract: Mainstream...

My colleague J.D. Meier asked for an example of what I consider to be a good pattern language . I could have recommended one of the languages that are by now classics in the patterns community . However instead of doing that I'd like to refer to examples...

Last week a group comprising Felix Nyffenegger, Judith Bishop, Duane Nickull, Marco Brambilla, Marco Egli, Michael Mahemoff, Patrice Pelland, Petri Selonen, Steve Burns, Wolf Logan, and Wei Wei joined me and Joe Yoder at the Web 2.0 pattern mining workshop...

Monday June 30 we're kicking off the Web 2.0 Pattern Mining Workshop at the TOOLS Europe conference, in Zurich, Switzerland. The submitted proposals focus on gadgets/widgets, gadget platforms, site navigation, and services. So far the confirmed participants...

We have two job opportunities in the Volta team: Software Development Engineer (232909) Software Development Engineer (232906) For more information please contact Erik Meijer .

During the last decade software patterns emerged as one of the most successful forms of reuse. The Gang of Four 23 Design Patterns , the POSA Architecture Patterns , Fowler's Enterprise Application Patterns , or the xUnit Test Patterns (to name just a...

********************************************************************* CALL FOR SUBMISSIONS 15th Conference on Pattern Languages of Programs (PLoP 2008) October 18-20, 2008 - co-located with OOPSLA 2008 Nashville, Tennessee, USA http://hillside.net/plop...

One of the things that surprised me at OOPSLA 2007 was the amount of traction that social media is getting. The crowd attending the 2007 WikiSym was larger than other co-located events that I remember from past OOPSLAs. Consequently I decided (with encouragement...

TechFest 2008 takes place this week in Redmond. The Seattle PI has a piece about it , and it's great to see Blews (BLogs + nEWS), one of the projects I'm increasingly involved with, mentioned in the article. If this piques your interest read Michael Gamon...

A few weeks ago I attended Lang.NET Symposium . Charles Torre asked me to participate in a conversation with Miguel de Icaza , who was among the attendees. (While nowadays most people associate Miguel with Mono, our paths crossed--virtually--many years...

Ajax patterns represent solutions to common problems facing the developers of Ajax applications. The patternhood of these solutions stems from the fact that they tend to come up over and over again; they're not one-offs. The book Ajax Design Patterns...
