Temporary Debian mail outage

It would appear that debian.org rejected mail for maybe up to twelve hours from late yesterday afternoon (Central timezone) to some time shortly after I got up this morning. Things appear to be back to normal, so a big Thanks to the mail admins. If you happened to have sent me mail to my debian.org address during that time period, you may have...

Brad Mehldau at the CSO

Just got home from a wonderful concert by Brad Mehldau at the CSO. This was long overdue as I kept reading about Mehldau. And even though he performs quite regularly around here, I had never seen him. Big mistake. The first set was performed as a (strictly acoustic) trio with Larry Grenadier on bass and Jeff Ballard on drums. After several compositions...

By

Thanks to the effort of the tireless Borja Sotomayor for the local ACM chpater as well as the good folks at Google in Chicago, we had a local kickoff meeting for this year's Google Summer of Code at Google's Chicago office. A few accepted GSoC students, mentors, and a few Google engineers gave short presentations to a bunch of ACM-affiliated students from U of...

Slides from most recent R and HPC tutorial

April 29, 2009
By

A little earlier I put the slides from my Introduction to High-Performance Computing with R tutorial at the R / Finance conference last week onto my talks / presentation page. Other tutorials, talks and keynotes are also being posted on the conference program page. This tutorial was a shorter format of just an hour which did not allow for any parallel...

Google Summer of Code 2009: R / Quantlib

April 28, 2009
By

With everything that has been going on of late, I have yet to mention that Khanh Nguyen, a Ph.D. student in Computer Science at U Mass / Boston, will be working with me on RQuantLib as part of the Google Summer of Code program this year. We had twenty-two applications to review for the R project, including three for the RQuantLib...

Review of ‘Analysis of Integrated and Cointegrated Time Series with R (2nd ed)’ in JSS

April 27, 2009
By

A few weeks ago I wrote up a short review of Bernhard Pfaff's nice (but somewhat dry) Analysis of Integrated and Cointegrated Time Series with R (2nd ed) on unit root and cointegration modeling with R. This is now online at the Journal of Statistical Software.

R / Finance 2009

April 26, 2009
By

Our inaugural R / Finance conference, mentioned here twice is now over. We were fortunate to get seven outstanding invited keynote speakers, as well as eleven excellent presentations. This was preceded by four short tutorials (and I'll post slides from my Introduction to High-Performance Computing with R soon). With about 150 registered participants, plus keynoters, presenters, committee members, representatives from the sponsors (a quick shout of...

Real nice Boston Marathon writeup

April 23, 2009
By

This article from the Boston Globe gives an excellent description of what running Boston last Monday was like, and why we keep coming back, almost regardless. The writer, for whom it was the fifth Boston and ninth total, expresses the range of emotions, expectations, frustrations, excitements, ups, downs, ... all of which form the challenge of racing a marathon in general, and...

Boston Marathon 2009

April 22, 2009
By

Monday was the 113th Boston Marathon. Just like in 2007 (and having skipped last year as I ran London the week before), I went as part of a group of local running friends. We once again had a blast---Boston on Marathon weekend is a real spectacle. Lots of people, lots of excitement, and this time even great weather. The race...

New Garmin Forerunner

April 10, 2009
By

Going for a run--or a race--almost always meant grabbing the GPS and often also meant setting a target pace and distance. For the last four and a half years, this was measured by a Garmin Forerunner 201. That's the large rectangular model in the original "brick" form factor. I've come to love the device. Training is great because the distance log, as well...
