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.

After I couldn't log in AGAIN, I pulled AMD Catalyst from Fedora 20

Once again, I did some updates on my Fedora 20 system. And after happily suspending and resuming the laptop for days, I crashed in the OpenShot video editor and had to do a hard reboot.

Except that I never got to the login screen. Just like the last time this happened, I suspected that the Catalyst driver I downloaded and installed from AMD's .run package was not playing well with the latest kernel from Fedora.

So I did what I did the last time this happened:

I paused GRUB, added a 3 to the bootline to boot into runlevel 3 and then removed Catalyst:

$ sudo aticonfig --uninstall

Then I rebooted the machine:

$ sudo reboot

At reboot, I was running the open Radeon driver again.

As I've said before, especially in kernel 3.13.x with Radeon DPM automatically invoked, performance is great. The system might run 5 to 10 degrees warmer than with Catalyst at idle. With a load, it's pretty much the same. That's what I've learned while watching CPU temperature over the past month or so. Once you start doing things, it's going to get hot.

With the 3.13.x kernel and Radeon DPM, video plays great. Even in full screen (as it should, but I digress).

The only thing that doesn't work? Suspend/resume.

We'll see how long I can take it this time.

Meanwhile, if you have any tips on getting suspend/resume working on somewhat modern AMD video hardware, I'm all ears.
