DJIA sources

See: Dow Jones Industrial Average for a list of data sources for the DJIA openings.

RSS/Atom

Phyzome's feed

This implementation IS FULLY 30W-compliant.

Subscribe to a feed that updates as soon as each day's meetup is calculable for your graticule:

https://lab.brainonfire.net/geohash.info/srv/feed.php?lat=LAT&lon=LON

If you visit the URL with no parameters, you will be prompted for your graticule coordinates.

  • Dow data comes from the peeron service
  • To view source, drop the parameters and change the extension to .phps -- this currently works for all PHP files in geohash.info/srv/
Quirks
  • The script estimates your timezone based upon your longitude, and uses -04:30 as the timezone of the Dow. Therefore, the update times may be off by as much as an hour or two. Shouldn't be an issue, since they'll be around midnight for most people.
  • For non-30W users, the feed will be empty between midnight and 9:30 AM -- this should be acceptable, since most feed readers keep entries that have dropped off the end of the feed. (This behavior may be changed in the future.)

Geo Hashing RSS

This implementation IS FULLY 30W-compliant.

Another RSS implementation, coded by Matty K. This one simply provides a graticule's coordinates for a given day, and gives links to both Google maps and the peeron maplet. It is recalculated at every request (so please don't hammer it, or my website will run out of bandwidths).

http://geohashing.kerwin.net.au/rss.php?ll=LAT,LON

For example, the link for San Francisco's feed is: http://geohashing.kerwin.net.au/rss.php?ll=37,-122

Notes:

  • If latitude/longitude are not given, it defaults to my home graticule .
  • I don't know if it supports negative zero. If there is a request to add specific support, please let me know. I added specific negative zero support, and tested it with the London area. It appeared to work okay.
  • 30W-compliance is based on the fact that I live East of 30W, and it gives me the right coordinates each day.
  • For any bug reports or other features requests, please email Matty
  • Sources can be made available by request. Although Matty might be a little ashamed of the shoddy code.

Automatic Daily Notifications

After registering, it will automatically notify users about all hashpoints as soon as they become available. Graticules are divided into 100 sub-graticules to allow users to only be notified when a hashpoint is near home, or alternatively, for all accessible hashpoints in a graticule. For more information, see the program's page.
