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 conquer the fan

I finally did get my fan under control in Puppy Linux. It involved modprobe commands for both the fan and thermal modules (I configured them to start on boot) and getting a cron job running to check CPU temperature at 5-minute intervals and turn the fan on or off depending on temperature.

I'm working on writing the whole thing up. But first I want to thank the Gateway Solo 1450 owners and Puppy Linux users whose expertise I drew on to get it done.

Even with the cron job running, I think the fan runs less under Debian and Ubuntu. There must be a different set of parameters for determining fan status. Perhaps cron's check every 5 minutes of the CPU temperature is a much longer interval than those other systems use. I'll have to look into it.

Another thing I'll be looking into is what my "trigger" points for the fan are. I currently have it set to start at 50 C and stop at 40 C. Maybe I can shift those numbers a bit to have the fan run less but still keep the CPU at an acceptable temperature.

While I'm giddy as shit at being able to run Puppy without the fan blasting the whole session, I'm still not as satisfied as I would be if it were managed as well as Debian does in EVERY Linux distro I use. But at least I can take what I learned in Puppy and try it in other distros that don't control the fan on this laptop. I'd love for this to work in BSD, too, but who am I kidding? I'll have to try my shell scripts and modprobe commands in BSD and see what happens. Probably nothing.

thing bothers me, though. If I were running a fanless PC, this wouldn't be a problem. It makes me want to build a fanless mini-ITX VIA box with parts from the Damn Small Linux Store or Logic Supply. And why can't their be a fanless laptop? If only I had enough skill, time and crazy-in-the-headness to build my own laptop. (I know this one has a fan, but I'd do it sans fan.
