Fibre Channel over Ethernet ( FCoE ) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol. The specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard published in 2009 (As descripted on Wikipedia)
I just orphaned the FCoE packages for Debian. I don’t really have the time and enthusiasm to maintain FCoE any more.

I am very pleased to announce the release of Laptop Mode Tools , at version 1.65
This release took a toll given things have been changing for me, both personally and professionally. 1.64 was released on September 1st, 2013. So it was a full 9 month period, of which a good 2-3 months were procrastination. That said, this release has some pretty good bug fixes and I urge all distribution packagers to push it to their repositories soon.

Starting yesterday, I am a happy user of the Basis B1 (Carbon Edition) Smart Watch
The company recently announced being acquired by Intel. Overall I like the watch. The price is steep, but if you care of a watch like that, you may as well try Basis. In case you want to go through the details, there’s a
pretty comprehensive review here.
Since I’ve been wearing it for just over 24hrs, there’s not much data to showcase a trend.

I just released Laptop Mode Tools @ version 1.64. And am pleased to introduce the new graphical utility to toggle individual power saving modules in the package.
The GUI is written using the PyQT Toolkit and the options in the GUI are generated at runtime, based on the list of available power saving modules.
Apart from the GUI configuration tool, this release also includes some bug fixes:
Don’t touch USB Controller power settings.

As someone who learned computers on his own, I always acknowledged the value that the Free Software movement has brought. The accessibility of these topics, which are only supposed to be part of text books and schools, is available for anyone and everyone who has the resource and passion to do it.
But this past week, 2 things made me pretty impressed with the maturity and quality of work that we do.

It is still 2012 in this part of the world and the world is still intact.
Since nothing major happened, I thought of spending the new gifted time to add
a long pending item to apt-offline. As shown in the screen shots, apt-
offline’s GUI now has support to detect and display the downloaded offline bug
reports. 
This is part of the just released, version 1.3.

Hello World. This is the follow-up to the last [2](http://blog/report-bugs- with-apport) updates on the state of apport in Debian.
A lot has changed since the last update on Apport. Currently, in Experimental, we have version 2.6.1-2. With this version, and going forward, there will be no hacks to make it work for Debian. Thanks to Martin Pitt, with his assistance, Apport now has a very basic crashdb in place for Debian.

This is a follow up to the previous post regarding Reporting bugs with Apport
Apport, version 2.2.3-2, has been pushed to experimental. There were some nice feedback that led to some more changes that I will talk here.
**Opt out: **As a developer, if you see the volume of reports to be annoying, you have the option to opt out of apport reports. To do this, you should specify the XBS-Apport: No field in your package ’s control file.
