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.

With the final package, [fcoe-utils](http://packages.qa.debian.org/f/fcoe-
utils.html), clearing the NEW packages queue, the Open-FCoE project’s Fibre
Channel over
Ethernet stack is
now in the Debian archive. I had anticipated to have access to FCoE hardware
by the time the packaging would complete but that didn ’t work out. It has
been delayed, hence the packages are in experimental. If you have access to
FCoE hardware, please test and provide your feedback.

So my friend game me a cute little birthday present, a Motorola S9 Bluetooth Headset.
Making it work under Linux was not very difficult but still has to catch-up in terms of utils.
To make the headset work, I just had to run a scan on the Linux host, and get the hw address and specify it in .asoundrc.
pcm.bluetooth {
type bluetooth {
address = xx.xx.xx.xx.xx

Most people who’ve bought laptops, would see a pre-installed version of Windows, for which they’d have already paid. Recently things have changed but still for the majority of the laptop models available, Windows is the most commonly used option.
I own a Dell XPS M1210 which too came pre-installed with Microsoft Windows XP. Since the machine was low on hard-drive space, I had to eventually knock-off all Non-Linux partitions to make more space.

Thanks to Pierre Chifflier , Debian now has setroubleshoot packaged. The good thing about setroubleshoot is that it gives you a very user friendly message about the SELinux violations that occur on your box while you were doing something.
Now that something is very difficult to define (at least for Debian). My day job requires me to work on the RHELdistribution which has very good SELinux policy defined (Same is the case with Fedora).

A couple of years back (or maybe still), it was difficult to find Device
Support in Linux from the Hardware Vendor.
Recently I was at home on a small vacation. There something surprised me. I
bought a device which had a logo saying, “Designend for Linux”. Cheers!

I’ve been working on a bug recently related to udev which under certain circumstances triggers an OOM on the Linux kernel. On another bug, I also wanted to look for the max open processes for a single file. The results I found and pretty good. The Linux Kernel’s OOM feature has imporved a lot.
This is the one liner used to trigger the OOM.
while true; do tail -f /tmp/test.txt & x=expr $x + 1; echo $x; done

ctime, atime and mtime
It is important to distinguish between a file or directory ’s change time (ctime), access time (atime), and modify time (mtime).
ctime -- In UNIX, it is not possible to tell the actual creation time of a file. The ctime–change time–is the time when changes were made to the file or directory ’s inode (owner, permissions, etc.). It is needed by the dump command to determine if the file needs to be backed up.
