screensaver

A Scala “Word of the day” shell script

I have a 19" monitor on the counter between my kitchen and living room, and it’s powered by a Raspberry Pi. I use the Linux Phosphor screen saver to show a scrolling “news and stock ticker” on the display, which I’ve programmed to show news from several different sources (Atom and Rss feeds, along with other news and data sources). An old version of the display looks like this:

Today I added a new “Word of the day” feature to the display, and as with all of the other code, I wrote a Scala shell script to generate the output.

An Ubuntu screensaver shell script to rotate images

This is a Bash shell script written for Ubuntu (Linux). I just switched from Mac/MacOS to Ubuntu, and I don't like the default blank screensaver in Ubuntu. I just want a screensaver to rotate my collection of images, so I'm considering using this rather than Xscreensaver. The script comes from jamcnaughton.com.

A Python script to read RSS feeds (and much more)

With the caveats that (a) I don’t know much about Python, (b) I don’t want to learn that much about it right now, and (c) I’m not concerned with performance at the moment, the following Python script does the following:

A Python screensaver for xscreensaver (Linux)

I know remarkably little about Python and GTK, but from the two URLs shown in the source code below I was able to piece together a working, “Hello, world” screensaver. Well, calling it a screensaver is a stretch, because what it will really do is burn the characters “Hello, world” into your monitor; but at least I cracked the code on how to get this started.

To try this on your own Linux system running xscreensaver, first save the following source code somewhere. I’ll assume that you’ve saved it to /home/al/hello.py:

A simple Python feedparser script

As a quick example today, the following source code is for a Python feedparser script I wrote, based on the URL shown:

Set your Mac screensaver as your desktop background

A Mac screensaver desktop tip: Hey, it's almost Friday -- wanna have some fun? How about setting your Mac OS X screensaver as your desktop background? If you set your Mac screensaver to something interesting, this can make for a very cool, animated desktop background.

I was just reminded of this Mac screensaver desktop background trick when updating my website and I ran across it again. Here's how to do it:

1) Open a Mac OS X Terminal
