I am pleased to announce the release of Laptop Mode Tools, version 1.67. This release has many important bug fixes, and everyone is recommended to upgrade. Of the many, one important fix is to, more reliably check for Device Mapper based devices, which is common these days with Crypt and LVM. For the summary of changes to quote from git log: 1.67 - Thu Jul 2 17:05:07 IST 2015 * Relax minimum window size to accomodate low res screens * Fix variable name to comply with our "constants" assuptions * Get more aggressive in power saving for Intel HD Audio * Account Device Mapper devices * Add swsusp freeze support * Switch battery-level-polling default to True * Detect ethernet carrier, early and relibaly * changes the boolean setting *_ACTIVATE_SATA_POWER to a customizable *_SATA_POLICY, with backward-compatible defaults and documentation Thanks Yuir D'Elia PS: On a side note, over the years, Linux’s power savings functionality has improved a lot, all thanks to its use in the mobile worlds.

I recently acquired a [Lenovo Yoga 2 13](http://www.cnet.com/products/lenovo- yoga-2-13-inch/). While, at the time, the Yoga 3 was available, I decided to go for Yoga 2 13. The Yoga 3 comes with the newer Core M Broadwell family, which, in my opinion, [doesn’t really bring any astounding benefits](http://www.digitalversus.com/laptop/lenovo-ideapad- yoga-2-13-3-p18512/test.html). The Yoga 2 13 comes in mulitple variants worldwide. Infact these hardware variations have different effets when run under Linux. My varaint of Yoga 2 13 is: [Read More]

Another of my articles for self. Writing it down on the website is much better than pushing it on a 3rd party social site. Your data is yours. My site runs on Drupal. Given I’m not a web designer, it is not my core area. Thus I’ve always wanted to have minimal engagement with it. My practices have paid me well so far. And I should thank all the free tools that help do that. [Read More]

This article is for self, so that I don’t again forget the specifics. The last time I did the same setup, it wasn’t very important in terms of security. gitolite(3) + gitweb can give an impressive git tool with very simple user acls. After you setup gitolite, ensure that the umask value in gitolite is approriate, i.e. the gitolite group has r-x privilege. This is needed for the web view. Add your apache user to the gitolite group. [Read More]

One of the great things about Debian is the wide range of kernels it supports can run. This gives the user the flexibility to not spend time on the common userland stuff. For example, most apps, package management and system admin tasks are common across all Debian platforms. These platforms may not be optimal at par to Linux, but still, choice is good. For long, I had used Debian GNU/Hurd, only on a KVM hypervisor. [Read More]

Looking at the PTS entries, I realized that it has been more than 2 yrs, since I pushed the first Apport packages into Debian. We have talked about it [in the past](http://www.researchut.com/blog/report- bugs-with-apport-3), and do not see a direct need for apport yet. That is one reason why it still resides (and will continue to) in Experimental. Even though not used as a bug reporting tool, Apport can still be a great tool for (end) users to detect crashes.

I am pleased to announce the release of apt-offline - 1.6 This release is mostly a bug fix release, which every user should upgrade to. It also fixes a major bug in the way we limited the validation of GPG integrity, for the APT repository lists ( Thank you Paul Wise ). Also, In the last release, we migrated from custom magic library to the python shipped ctype python-magic library. That allowed some bugs to creep, and hopefully now, all those bugs should be fixed.

Dear Lazy Web, I have an [HP Envy J104TS](http://www8.hp.com/us/en/ads/envy- touchsmart-15/specs.html) laptop. Recently I saw an interesting message in the kernel log. [99360.969652] [Firmware Bug]: battery: (dis)charge rate invalid. Does anybody know what firmware is it referring to here ? I don’t think the current set of firmwares shiped by linux are involved in battery related information. Is it the BIOS ? [95474.561491] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [95474.803578] r8169 0000:0f:00. [Read More]

Linux has improved many many things over the last couple of years. Of the many improvements, the one that I’ve started leveraging the most today, are Control Groups. In the past, when there was a need to build a prototype for a solution, we needed hardware. Then came the virtualization richness to Linux. It came in 2 major flavors, KVM ( Full Virtualization ) and Xen ( Para Virtualization ). Over the years, the difference of para vs full, for both the implementations, is almost none. [Read More]
