I had a great time presenting this year at the annual TNGIC 2011 GIS Conference. If you are a GIS student or professional in the Tennessee area, this annual conference is a good way find out how others are working with GIS.

My talk this year was entitled Great Maps with Less Work: Getting the most out of ArcGIS Online. If you have not already given the free ArcGIS Online Services a try, you might be missing out on something that really would make work easier.

Curious to learn more? Here are the slides for my session, and feel free to contact me at GISbiz for more info. Enjoy!

Here’s one of mine …

# This template prints the files included in each changeset.
changeset = "{node|short}: {desc}\n{files}\n"
file = "  {file}\n"

Which formats the output like this …

e9f2c463e105: increment version for push
  setup.py
 
98c2272ab7ff: apparently sdist was broken.
repair MANIFEST to include ez_setup properly
  MANIFEST
  MANIFEST.in
  setup.py

The uploaded file could not be moved to /usr/local/apache2/htdocs/your-site/wp-content/uploads.

Most of the advice you will find is about file and folder permissions, but this error is also displayed if your file is too big.

Two MB is the default setting in php.ini for upload_max_filesize, so if this is your problem, just increase the value and restart apache.

Happy Programming!

Getting messages like this to thousands of people in mere seconds is awesome!  Now we just need a photo to go with it.   I bet there is an iPhone app for that.

GIS Stack Exchange started a private Beta today and opens to the public in one week.

8/1/2010 Update: Now open.

Hudson is great for managing scheduled builds, but after a while the artifacts start to take up a considerable amount of space.

Deleting them one by one is possible, but Hudson will do this for you:

Note that this works retroactively. If you have 300 old builds and set the job to keep just 20, the next build will delete 281 builds.

These instructions are based on a stand alone installation of Flex Builder, but I suppose they are about the same even if you are using the Flex Builder Eclipse plug-in.

1. Click Help > Install New Software …



2. Click ‘Available Software Sites’



3. Click Add
4. Enter a name and the url (http://hge.javaforge.com/hgeclipse), click OK



5. Click OK again to close the parent window and select ‘Mercurial Eclipse’ in the ‘Work with’ drop-down list.



6. Select HgEclipse and click Next, Next, Next, Finish



7. Now open a project.  Right click the project, select Team > Share Project …



8. Choose Mercurial (obviously) … click Next, Next, whatever, to finish the selections.



9. Finished!  You should now see the Mercurial commands in the Team menu.



P.S.  Mercurial ROCKS !!!!  I’ve used VSS, Perforce, TFS and Subverion.  Subversion has always been my favorite, but Mercurial easily takes first place now.  The DVCS model is much better.

Quick Tip: Is your site suddenly requesting a user name and password?

Most likely this is triggered by insufficient file system permissions. The error logs at
%SYSTEMROOT%\System32\LogFiles\W3SVC###\*.log will narrow down your search and give the substatus and Win32
error codes for each HTTP 401.

David Wang has a great write up about this on his blog. Check it out for more details.
