I have a dream of having one of these buildings (slideshow at Wired.com) in my back yard as a home office someday. Another dream is to get an acreage and scatter several of these buildings around with some paths connecting them together.

Gever Tulley has a great video about the sort of dangerous things kids need to do when growing up. It is nice to see this kind of thing. Its a breath of fresh air from the fear society we live in. On a related note, kids don’t get the freedom to go out walking and exploring much anymore.

Just did a stupid thing and deleted a whole tree of file on a windows partition. Never fear…ntfsundelete is here.
sudo ntfsundelete -u -d /destination/directory -f -m *.jpg /dev/sda1
Run without the -u option and -d options to show what can be recovered.
On ubuntu/debian to install it do:
apt-get install ntfsprogs

I am making the plunge to get more informed with how to use PostGIS. It is pretty impressive so far. Here is a quick tutorial which shows you how to get started and loading in a shapefile to play around with some fun SQL querying. I assume a basic understanding of the linux command line and some basic SQL skills.
To get started in ubuntu 7.04 (should work in 7.10 and debian too):
$ sudo apt-get install postgis postgresql-8.1-postgis
Next we’ll start setting up the PostGIS environment.

Just whipped together an animation of the San Diego Fires from some recent MODIS scenes that I grabbed from the MODIS Rapid Response System. I put the animation together using GIMP.

So, I receive this letter in the mail about once per week for the last 3 months telling me I have a balance in my United Mileage Plus account. It says I have 6,904 miles, that plus the 21,500 I’ll get from United will let me get enough for a free ticket which runs 25,000 miles, oh boy! Never mind the $60 annual fee, the 18.24% APY, I can get a free ticket baby…I can go places…see the world.
Wait, what is that…there is an asterisk there…what does it say about that. “Based on mileage plus account balance as of 6/1/07. United Mileage Plus is not liable for mileage balance misprints.” Hmmm…alright.
Ok, well lets go check united.com:
What’s this..my miles expired on 06/30/2007, leaving me with a balance of 0.
So the notice I have been receiving every week for 3 months straight has been grossly misleading and too good to be true. I know the airlines are hurting….but c’mon guys lay off the deceptive marketing practices.
