CryptoLocker

Renee’ clicked on a CryptoLocker attachment. [sigh] I’ll be damned if I’m going to reward those defectors for their behavior. So, we went to a local computer shop and bought a new one for her. (That allows me to study the infected one at my leisure.) She lost quite a lot of work. But nothing time sensitive that she can’t regenerate over time.

Normally, I’m relatively accepting of black-hat behavior. Cracking into low-hanging fruit and demonstrating flaws in the systems of the sanctimonious, although still defector behavior, serve a useful co-evolutionary purpose.

But I can’t abide hostage taking. And to anyone tempted to pay the ransom: Please don’t reward them. The more money they make, the more depraved they’ll be.

Gnome3 lockscreen background

Written by  on November 14, 2013

For whatever reason, sometimes when I lock my screen it eventually blanks and sometimes it doesn’t. Since I prefer solid black backgrounds on pretty much everything anyway, I figured I’d change the lockscreen background and GDM login screen to my usual black-pixel background.

Here’s how I did it:

$ cd /usr/share/images/desktop-base
$ cp joy.xml black.xml

edit black.xml like so:

5,8c5
< /usr/share/images/desktop-base/joy-wallpaper_1280x1024.svg
< /usr/share/images/desktop-base/joy-wallpaper_1600x1200.svg
< /usr/share/images/desktop-base/joy-wallpaper_1920x1080.svg
< /usr/share/images/desktop-base/joy-wallpaper_1920x1200.svg
---
> /usr/share/images/desktop-base/black-pixel.png

then

$ sudo update-alternatives --install /usr/share/images/desktop-background.xml desktop-background.xml /usr/share/images/desktop-base/black.xml 100

Then logout and login, check your lockscreen.
