Recovering GRUB after windows installation

I finally used my windows upgrade kit to upgrade my laptop from windows Vista to Windows 7. This has been too much delayed because I use ubuntu lucid mostly anyway :). One of the side effects during the upgrade is to load the GRUB loader menu from which I select the OS to load. Windows overrides that upon installation so it is completely by passed. Luckily, this is a well covered topic at ubuntu forums since it is a likely thing to occur A nice guide on how to restore the grub menu can be found at This is useful if you are using GRUB2, ubuntu 9.10+ To summarize: Use a live CD to boot ubuntu on you computer mount the system partition (or the partition having the /boot directory) in the original installation of ubuntu that you have to a specific location (say /meda/ubuntu_sys) use the grub-install command: sudo grub-install --root-directory=/media/ubuntu_sys /dev/sda Reboot your system and , voila,

chrome/blogger incomptability ?!!

This issue has been buzzing me for a while now since I started using the Linux version Google Chrome . For some reason, when I try to publish a comment on a blog post on google's, I get nothing, absolutely nothing, the page just refreshes when I click the publish button. I have to move and open the page in Firefox in order to proceed posting my comment. I hope whatever the conflict was, that chrome team fix it on this beta version.

Ruby script for downloading rails casts

Ryan Bates continuously provide useful Rails tips in this . I had written a bash script for downloading the videos of the episodes in the past. I do not like streaming much and I'd rather keep the episodes for reference. One downside of the script is that I had to check the rss feed or the website for new episodes, and run the script manually passing the correct paramters (start and end of episode ids to be downloaded) Now I decided to get rid of the silly step. so I ported my script to ruby, and it runs down to download whatever episodes are missing using the rss feed and checking what is already present. The script uses simple-rss gem, so you'll have to get that installed. It also uses wget for downloading. I didn't bother using net/http of ruby, wget is fine for me as a linux user. The script flow is simple: Check the current files in the download directory (collecting information) Grab the rss of Iterate over rs

Gmail search and labels.. a wished feature

Gmail has been my main email engine for years now. I'm totally comfortable with it. The ability to process, distribute and keep up with the flood of emails i get everyday from different resources, and the ability to search and find emails (even the very old ones) easily are the keys behind my loyalty to gmail. Gmail supports some nice techniques that can be used while searching emails. Besides what you can use in the advanced search form. the command line approach (direct control from the simple search box) proves to be even more powerful. Anything that can be controlled in the advanced search form, can also be done from the simple one provided that you know the right parameters. You can specify: to, from, subject, a label, ... What's more exciting is that you can specify several labels to search in, and several labels to be excluded from search. By default you have "read", and "unread" labels. A frequent search query of mine is "l:inbox l:unread&quo
