Intel 7260AC Bluetooth [8087:07dc], Ubuntu, and the Thinkpad T440p

This requires a little magic, unfortunately; either the driver, system, hardware itself, or some combination thereof do not operate well with autosuspend enabled. Disabling autosuspend for this device does appear to resolve dropped / corrupted / weird bluetooth issues. Based on my googling, I do not believe this to be Thinkpad-specific, rather something the Intel 7260AC firmware isn’t handling properly at the moment. FWIW, I’m running Ubuntu 13.10 (saucy) on the thinkpad in question, and 12.

docker without password prompting

Just a little snippet.┬áThis should be pretty obvious to those familiar with how sudo functions, but it’s easy to run docker commands with sudo without being prompted for your password by configuring sudo to not ask for it. Note that the normal warnings and red flags apply here. If you install the above as /etc/sudoers.d/docker, then the user rsrchboy (line 1) and any user in the docker group (line 2) will not be asked for a password when running “sudo docker …”.

Useful git defaults -- systemwide

Sometimes it’s necessary to – for one’s sanity, if nothing else – to establish a set of generally non-controversial, sane, system-wide git configuration defaults. This is largely helpful when multiple people are using the same system who may not have a standard ~/.gitconfig they carry around with them. To do this, we can leverage the little-used system-wide git config file at /etc/gitconfig. Remember that by default git looks at three files to determine its configuration (in ascending order of priority):

screen, vim, tabs, and C-PgUp/C-PgDn mappings

I use screen with vim. One of the things I like about vim is that, much like unix itself, I’m always discovering useful new features, even after years of use. Recently, I’ve been using tabs in vim to complement window regions. I’ve found it pretty useful, as there are times I’d want to keep certain tasks on one tab but not another. e.g. different source files open in windows on one tab; a test file + vim-pipe buffer showing the rest.

My first YAPC::NA!

I’m in lovely Madison, WI right now, and will be headed over to my first YAPC::NA tomorrow. The first couple days are the hackathon, at which I think I’m going to work on a Dist::Zilla::Role::Stash to hold repository related information. There are a bunch of Git related plugins for Dist::Zilla, a couple that I maintain, and a lot of code is duplicated between them; a stash should resolve that. I hope to meet you all there!
