Yesterday was a big day for Ubuntu community since three main desktop releases reached their End Of Life. For Hardy Heron (8.04) servers it’s urgent to upgrade to Lucid Lynx (10.04 LTS) -at least- to benefit of other two more years of updates.

All -I am writing to apprise you of two small but important changes coming toFirefox in Lucid. I have asked the desktop team to start preparingthese changes to make them available in Lucid as soon as reasonablypossible. Probably on the order of weeks.Change #1In Lucid, the default home page will respect the search providersettings that you have set in the "Chrome". (The "Chrome" is Mozilla'sterm for the little search box to the upper right, reachable bycontrol-K, for instance). For Lucid, this will definitely work forswitching between Google and Yahoo!, we don't yet know what otherproviders will be in scope for Lucid. If a user has Google set as theirsearch provider,they will have exactly the experience they do today. Ifthey switch to Yahoo!, the default home page will switch to using aYahoo! search. If they switch back to Google, the default home page willswitch back to using the Google search, exactly like today. Searchingfrom Chrome will continue to work exactly as it does today.Change #2Change #2 is changing the default search provider in Firefox to Yahoo!Note that this won't in any way effect the ability of a user to chooseand use the search provider of their choice. It's literally 2 easilydiscoverable clicks to change this setting, a simple matter of switchingto that search provider in the chrome by clicking on the icon andchoosing the desired provider. Note also that Yahoo! does not share anypersonally identifiable or usage information.Why?I am pursuing this change because Canonical has negotiated a revenuesharing deal with Yahoo! and this revenue will help Canonical to providedevelopers and resources to continue the open development of Ubuntu andthe Ubuntu Platform. This change will help provide these resources aswell as continuing to respect our user's default search across Firefox.Cheers, Rick
Did you ever find yourself at work with a remote session on your Ubuntu server (or workstation) invoked by ssh -X command and needed to launch users-admin or some similar graphical application that need a sudo (or root) authentication to work?
Did you ever got frustrated of not having the possibility to enter or see accepted your password ?
Well, here’s how to resolve this! All you need to do is invoking this command:
sudo ck-launch-session $command &
For example, when I needed users-admin (to graphically add a new user, modify or delete an old one) giving the aforementioned command, after having inserted my sudo password, I got this window:
P.S. = if you can help me with a shorter or clearer post title I’ll be grateful (remember english isn’t my native language !!!)
P.S. #2 = sometimes you just DON’T have to put the ‘&‘ at the end of the line so you can insert the administrative password needed for the command (i.e. Synaptic) execution…
Lately I had the necessity to create an account and modify another one on an Ubuntu box at work. I’ve regularly logged on via a ssh -X shell and gave the command
resulting in a “blocked” window … I mean one on which I wasn’t able to unlock the command via an administrative password input.
After a little diggin’ on the web I found that the solution is in giving this command:
sudo ck-launch-session users-admin &
which will ask you the administrative password and make the commands on the appearing window
Today I’d like to spend some words on a particular Open Source project which aims to make know, test and finally use the available tools for molecolar biology, bio-technologies and bio-informatics in general.
This world is overwhelmed by a number of “tools” divided in an ocean of productors, licences, repositories and kind of package (rpm, deb, Z, tar.gz, plain code…).
This NEBC proudly has took in hand this shattered cosmo of open source software for bioinformatics under his own “umbrella” and then has gone further … has created a full GNU/Linux distribution, building over the solid core of Ubuntu (on it’s Long Term Support 8.04 release).
Today Bio-Linux 5 is:
- a LiveCD operating system;
- a fully functional operating system running on desktop and servers alike;
- a bioinformatics repository for Ubuntu
and all this is fully supported and given the news on the NEBC and NERC there’s money to guarrantee that for the expectable future.
Personally at work I’ve had chance to appreciate this distro in all the flavours listed above and also as a VMware’s appliance.
If you’ve already running an Ubuntu 8.04 box in this wiki page you’ll find how-to add the biolinux repository to your sources.list. There it’s also stated that there’s some kind of compatibility with Debian and also with the latest 9.04 release, even if for a couple of software there are occasional bugs.
But, on the workplace, expecially when the user has to USE his desktop and not work to make it run, Ubuntu 8.04 (with an updated copy of OpenOffice and a couple of backports) it THE way go, at least for me.
As a personal, final note, I must regret on the strickt control of the repository … I’ve witnessed a similar Biolinux project, focused on the RPM world being abandoned in 2007 supporting ancient distros like Fedora6 and RedHat 9 … I’d prefer a strong team in the Ubuntu (or $distro) community claiming “we will take care of all things bioinformatics, like it’s done for Compitz or other focused projects in the past.
A change of menthality is needed so, when the Public Administration (or a private) invests on an open source technology the RoI must be seen in the product itself (and/or on how it facilitates works or makes you make more money increasing the productivity) and not in a self-owned fancy site claiming “I MADE IT, I AM BIG, GIMME MORE MONEY”.
Don’t you think so?
Ever wondered how to know by command line which version of Ubuntu are you running ?
The answer is simple:
kOoLiNuS@linuxbox:$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=8.04 DISTRIB_CODENAME=hardy DISTRIB_DESCRIPTION="Ubuntu 8.04.3 LTS"
Enjoy your Open Source operating system
