empty subject (no subject) in email with grails mail plugin

When sending email using the grails mail plugin, the email subject always ends up empty with (no subject)

this is a known problem. see the link
http://www.nabble.com/Grails-mail-plugin-0.5-:-subject-and-body-always-empty-td20008519.html

The problem happens if you have groovyws-all-0.4.jar in your lib directory. groovyws-all.jar also has javax.mail.* classes packed in there. The fix is as simple unjaring, remove the javax.mail package and rejar it.

hope someone finds this helpful... spent a good half day researching this

skype on 64bit linux

skype doesn't provide a 64bit version for linux, but the 32bit version works fine on a 64bit linux machine. On ubuntu, force the install:

sudo dpkg --force-architecture -i skype-debian_2.0.0.72-1_i386.deb

tmobile hotspot wifi at borders/star bucks ubuntu linux on dell studio xps

Got a dell studio xps 13 (SX13-163B) and have ubuntu 9.04 running on it. Everything works great bluetooth keyboard/mouse, webcam (tested using skype). Wifi at home works without a problem. However when connecting to a tmobile hotspot at borders/star bucks, the wifi would randomly drop connection every few minutes or so which is very annoying and disruptive to my work. I did some experimentation. I disable the network manager then manually started the dhcp client by running:

% sudo dhclient wlan0

After that I was able to connect without interruption for 3hours now. Hope this info is useful for somebody

difficulty installing android plugin for eclipse ganymede

following directions at http://developer.android.com/sdk/1.1_r1/installing.html on installing the android plugin did not work.

apparently, the URL to the update site are wrong. The correct URL is
http://dl-ssl.google.com/android/eclipse/site.xml

https://dl-ssl.google.com/android/eclipse/site.xml does NOT work so use the http URL

add/removing rows from dojox.grid.DataGrid

There is a bug with dojox.grid.DataGrid when deleting a row and adding it back. When adding back the row, it must have a different id otherwise it would not work.

your sd should now be available at the mount point /mnt
