Bicycle Route Thru Concord, Carlisle, Sudbury, and Lincoln

Now that I've mapped some bicycle tours around Concord as shown here, today I combined and traversed the suggested routes. Two hours, two flattened turtles, one flattened skunk, one eighteen-wheeler, and many clumsy landscape trucks later, here's the stats on this combined loop:

2001 Giant Cypress DX


Garmin Forerunner 201
Time: 2:02 (2 hours, 2 minutes)
Distance: 28.47 miles or 45.5 kilometers
Average Speed: 14.0 mph or 22.4 kph
Average Pace: 4.3 min/mi or 2.7 min/km
Highest Speed: 30.7 mph or 49.1 kph (on Lincoln Rd, near Audubon Sanctuary approaching Rt 117)
Calories burned: 1,895 (estimated by Garmin's setting for body weight)




I prefer to strap the Garmin Forerunner to my Giant Cypress DX handlebar rather than my arm because it makes viewing much easier. Seeing my current speed and distance provides constant motivation. The velcro strap fits snugly around the handlebar when wrapped over the headlamp mount.

An easier way to take ColdFusion thread dumps on Windows

Thread dumps are often used a diagnostic utility to qualify and quantify the page requests running in a ColdFusion MX or JRun server. This is most useful for servers that appear to be hanging or spiking the CPU.

Brandon Purcell demonstrates how to generate ColdFusion MX thread dumps, also known as stack traces, while running it as Windows Service rather than from the command line.

Obtaining a Thread Dump with ColdFusion or JRun running as a Windows Service
While there is a limitation if using Terminal Services, this method will otherwise allow you to attach to a running jvm process to take a thread dump.



What to do with a ColdFusion thread dump once you've got it? This Macromedia technote on Debugging Stack Traces in ColdFusion MX helps make sense of it, although in my experience you have to read quite a lot of thread dumps before they start to look warm and fuzzy enough to be familiar, but that is when they start to offer up some of their secrets :)
