Locate Technology on the Map

Did some playing around with google maps API, searches for job listings and puts cities where technology is found on the map(works only for single words for now, like Ruby/C etc.)
Compare Ruby and C# for example... who would have tought, lots of C# in Seatle...
Also it doesn't work quite right where there are hundreds of matches like Java(I got tired of the HTML parsing....), might get back to it at some point.

Ruby script to send email with authentication and attachments

Here's a little script I wrote to send email in Ruby with smtp authentication and attachments, it needs tmail(included in Rails). It could obviously use more polish, I wrote it based on some samples in tmail, unfortunately the tmail docs are little lacking. Since I wrote it on linux/mac, moving it to windows was little tricky because Tmail ruby library includes c-code that needs to be compiled. However the rails package active_mailer includes tmail (I am not quite sure if it is exact same version as on the Tmail page), so I just had to figure out to require rubygems and active_mailer on windows in addition to Tmail.
Also as usual I got stuck for a while with the attachments on windows, since as usual I forgot the idiotic behavior on windows where attachment files such as docs or images need to be opened with "rb" flags to indicate binary file(not necessary on Unix like Linux and Mac), otherwise it won't error, but it will just truncate the file.

Now this can handle arbitrary number of attachments and you can put in toList things like in
#--tolist="toListProd.txt"
cc:
bcc
#and commments

Anyway here is the version that works on windows, for linux just remove the items mentioned above:

Ajax

Since I wrote about GUI toolkits it really seems world is further and further moving towards the web. I believe thick GUIs still have their place, where super fast performance like what wxwidgets can offer is required, however you can do lot with Ajax now, here's a little demo I wrote using Ruby Rails and prototype libraries, it has movable windows, drag-drop items, "push" updates, in-place edits, on the fly stylesheet changing etc.
Here's a screenshot:
