Regular blog here, 'microblog' there

Many of my traditional blog post live on this site, but a great majority of my social-style posts can be found on my much-busier microbloging site at updates.passthejoe.net. It's busier because my BlogPoster "microblogging" script generates short, Twitter-style posts from the Linux or Windows (or anywhere you can run Ruby with too many Gems) command line, uploads them to the web server and send them out on my Twitter and Mastodon feeds.

I used to post to this blog via scripts and Unix/Linux utilities (curl and Unison) that helped me mirror the files locally and on the server. Since this site recently moved hosts, none of that is set up. I'm just using SFTP and SSH to write posts and manage the site.

Disqus comments are not live just yet because I'm not sure about what I'm going to do for the domain on this site. I'll probably restore the old domain at first just to have some continuity, but for now I like using the "free" domain from this site's new host, NearlyFreeSpeech.net.

I'm running Linux kernel 3.2.0-15 from Debian Backports

After months and months on Linux kernel 2.6.39 from Debian Backports on my Squeeze laptop, I decided to give a newer kernel a try.

I'm only using newer kernels than the 2.6.32 that ships with Squeeze because the version of the ALSA sound system built into that kernel doesn't mute the audio on my Lenovo G555 laptop when I plug in a headphone jack. Kernels after 2.6.35 or so, which include a newer ALSA, fix this bug, and that's pretty much the only reason I'm not running the stock Squeeze kernel, which is updated regularly for security patches.

The Debian Backports kernels don't seem to update on their own. You need to periodically go in there, see what new kernels are available and install one.

I've had few kernel panics here and there in 2.6.39, so I figured that dipping into the 3.x era of Linux kernels was warranted.

There are two 3.2.0 kernels right now in the Debian Backports repository -- 3.2.0-4 and 3.2.0-15. I used 3.2.0-15, and so far all is running well. Sound works as expected. So does suspend/resume. And in a couple of days, I've experienced no kernel panics.

Absent my sound issues, I would have never used a "newer" kernel, and by the time I move this laptop to Debian Wheezy (or any other distribution with a post-2.6.35 kernel), I should be able to run that system's default kernel for the duration.
