Asus might have lost the netbook war to Acer, but it is fighting back as far as the keyboard PC wars are concerned. With the Consumer Electronics Show (CES) still a day away in Vegas, the geeky and gadgetry announcements are coming thick and fast.

[It looks great. No word about the OS yet, but the pics remind me of Plasma or OpenMoko, so it may be Linux -- Sander]

I've been a Linux user for some years now, and I've decided to start documenting the process I went trough. Today I might be seen as a Linux guru from the point of view of a starting user, from the point of view of a Linux guru I'm probably more seen as a starting user. I see myself as an intermediate, but even as my knowledge level might not be top level, On this day I do manage a business network, a few mail servers and web servers running a few hundred web sites.

From the 'it's not there yet' files: In my opinion, one of the greatest innovations of the Firefox 2 release was the inclusion of Tab Overflow. For the first time I could actually handle as many open browser tabs as I wanted. While Mozilla introduced Tab overflow in 2006, here we are in 2009 and Google Chrome doesn't have that feature. For someone like me that often keeps 10+ tabs open at any one time this is a (minor) problem.

On machines like Linutop or netbooks, running a graphical Twitter client is a waste of precious resources, so a command-line tool like Twidge can come in rather handy. Using it, you can quickly post tweets and view the latest posts from people you follow without leaving the convenience of the terminal. Moreover, Twidge supports Identi.ca — an open source micro-blogging service.

Starting in 2009 popular, autonomic configuration management tool, Cfengine will be commercially supported by a company formed by Cfengine author, Mark Burgess.

Hey Greg Davis: You’ve just been named Dell’s global channel chief -- in charge of the PC giant’s worldwide partner strategy. What are you going to do to drive new profits? Here’s one suggestion: Offer some Ubuntu PCs to Dell's worldwide partner network. Sure, Dell has successfully introduced Ubuntu PCs and laptops to the niche buy-direct geek crowd.

A long thread at LXer about whether or not Debian should include unsourced binary blobs in its kernel had some commenters if not exactly singing the praises of totally free GNU/Linux distro gNewSense, then at least humming those praises. The point was that if you really are bugged by blobs in the kernel, you should put your geek-boy money where your mouth is, eschew "compromising" distros such as Debian and Ubuntu, and use the Ubuntu-derived, blob-free, Free Software Foundation-approved gNewSense.
