This is more a note to self than anything else, as there are many posts already on the internet about this.
Recently I’ve needed to get mail on the road, and my employer’s policy forbids to connect a non-standard device to their network. So, a GPRS connection through the phone is an OK alternative. [...]

Yesterday I upgraded my Macs to Leopard. The main reasons for the upgrade were XCode 3.0, Time Machine and BootCamp. I had been using the latter very robustly on my machines. I read rumors a while ago about the BootCamp beta program ending for previous OS versions once Leopard was released, and I haven’t had [...]

Lifehacker posts this article about recovering lost pictures on memory cards. Mac OS X owners may want to try these two commands before purchasing additional software: dd and fsck. Linux users most likely already know what to do — if not, the instructions below are 98% the same…

This weekend I set up a backup wireless connection using my Bluetooth cell phone (Motorola RAZR v3xx). Pretty painless, thanks to Ross Barkman’s scripts, and Ed Thomson’s post.

Heyu is an excellent package for managing the X-10 CM11A serial interface (and some others, as well). I use it at home for automatically turning on and off lights. My home servers run Gentoo Linux, which gives a great amount of control over what packages are installed on your system and how these [...]

I’ve been recently working on some screencasts to demonstrate data analysis techniques.
Two common features I needed for my screencasts, which I’ve seen many screencasters also use/need, are:
Overlay of a small frame on top of the screencast. For instance, you may want people to see you while you are talking. With computers taking more [...]

I’m writing a portfolio management application in Rails where complex validations are required between fields of instances. The MVC paradigm of Rails is very good to encapsulate all the business logic of the application in a very readable way.

I had old scans of many guitar tab books as a directory of JPEG files, sequentially numbered. That was the way the old scanner stored documents. My SnapScan has an automatic document feeder and scans directly to PDF, which is much nicer to use. I wanted to join these JPEGs into a [...]

Scot Finnie writes this article on Computerworld named “A Windows expert opts for a Mac life, Part 2″ where he describes his experience moving to the Mac. His biggest hurdle to move was the transtion of Eudora mailboxes, and he ended up doing a very labor-intensive process:
The only thing that worked was to open [...]
