Prolong keyboard backlight timeout
View backlight_timeout.md

I have a Dell Inspiron 5570 (5000 series) and for some obscure reason in my default linux instalation the default keyboard backlight timeout is something like 1 second. Doesn't make any sense, what benefit does a keyboard backlight have if I can only see it in the dark only when I'm already typing?

Took a couple of wrong paths searching for a solution until I found how to manually tweak that value. Keyboard backlights configuration files are located under /sys/class/leds and for a Dell laptop the magic file is /sys/class/leds/dell::kbd_backlight/stop_timeout.

There's no option to disable the timeout completely so I've created a systemd service that sets the timeout to 30 minutes (just an arbitrary large value) each time graphical.target is reached.

LVM snapshots are logical volumes that reflect the state of the snapshoted volume at the exact moment in time the snapshot was created. Useful for backups and reference points we can revert back to.

Creating snapshots

$ sudo lvcreate --size 5G --snapshot --name root-backup /dev/vg0/root
  Logical volume "root-backup" created.

How to connect your PSP on Linux
View psp_on_linux.md

It should work by default when connected, however you might reach this page with the same issue I had, where you where missing a few essential steps.

  1. Be sure that your PSP is set into USB mode: Settings -> USB connection
  2. Be sure the kernel module usb-storage is enabled, you can check with sudo modinfo usb-storage and enable it with sudo modprobe usb-storage
  3. Reconnect your cable after trying any of the previous steps
  4. If it doesn't get automounted, run dmesg to find the device (on my local machine it's sdb as seen in the output) and mount it manually (prefered with your user access rights so you don't have to use sudo for file copy)

Sculpin for Github pages
View sculpin_for_github_pages.md

After a couple hesitating months to move to github pages, and from my hacked together static site generator, yesterday was my 4th attempt in getting started with github pages blogging, just because there where a few annoyances with the different variations I've tried.

Decided to go with Octopress, just for their nice logo. And for their Github pages oriented focus. That didn't pan out, but at least I learned a few things about their blogging process and setup, which I'm adapting for sculpin.
