As some of you may have noticed, Cyclogz’s estimates for cumulative ascent and descent can some times be wrong. Most notably, the difference between actual vs our computation could be way off for non-barometric GPS units like Edge 205.

Cyclogz currently uses a smoothing average algorithm to smooth out the data and then compute the cumulative ascent and descent. This algorithm is soon going to be replaced with a better algorithm. When that is implemented, all rides will automatically be adjusted. I will keep you posted.

By the way, my friend Sanjay is working on analyzing the problem and coming up with an improved algorithm.

To get the Garmin Communicator Plugin working with Safari 4, please remove “Flip4Mac WMV Plugin.webplugin” from the /Library/Internet Plug-Ins folder on your Mac, and then restart Safari.

Thanks to Gireesh for posting this tip in response to a previous post.

Just updated this feature to display a timer, speed, altitude, and distance. Please check it out.

Thanks to one of the cyclogz users, we found that upload don’t work with the latest Garmin Communicator Plugin (version 2.7.1) on Windows machines. We are working on a fix.

Update: Please download version 2.6.4 of the plugin from http://www8.garmin.com/products/communicator/ to resolve this problem.

I am happy to announce that we are working on supporting the same features as you see on Cyclogz to non-cycling related activities such as running and hiking. Please watch out for upcoming announcements.

We noticed yesterday that, after installing Safari 4 beta corrupts the Garmin Plugin, Cyclogz will not be able to load logs from your GPS. It turns out that the Safari 4 installation process itself corrupts the Garmin plugin. Here is how to fix it:

a. If your default browser is Safari, change it to some other browser such as Firefox

b. Close/quit all browser applications

c. Reinstall the Garmin Communicator Plugin

d. Then use a non-Safari browser to upload your logs.

These steps work on Mac OS X. We do not know yet know what happens on Windows XP or Windows Vista machines. if you have any info, please let me know.

After half-a-day of prototyping, and a another half-a-day of coding, I updated Cyclogz to geotag all my riding pictures. The process is quite simple:

• Set the camera to the local timezone, and take pictures.
• Update ride logs from Garmin Edge/ForeRunner to Cyclogz.
• On the ride page at Cyclogz, select to add photos. This will ask you to authorize Cyclogz to access Flickr account, if not already authorized
• Cyclogz will search user's public photos that match the ride, and geotag them automatically!

All 600+ photos that I took in 2007 and 2008 are now geotagged, and can be browsed on the map at http://www.flickr.com/photos/subbu_allamaraju/map.

This week, I rewrote the upload page to make the upload process more intuitive and interactive.

One major change you will notice is that you can now edit the ride title on the upload page itself. Just click on the ride title to edit it on the upload page.

Over the last few days, along with a revamped home page, I added new code to detect the GPS right from the home page. Hope this simplifies the upload experience. More changes are coming soon.
