The origins of my computing journey

from Paolo Amoroso's Journal [alt+shift+b] in programming

4 weeks ago
<![CDATA[My journey to using and programming computers started around 1983 with a Sinclair ZX Spectrum 48K, the very first I owned. At the time I was clueless. For example, I wondered whether, once I loaded a program from tape, I needed to write it back at the end of the session...

When Google killed Google Reader, the bloggosphere took a severe hit and the content quality went down because there weren't enough readers to justify the effort it takes to maintain a high quality blog.

What's left is a decaying wasteland of blogs, most abandoned, a lot are now SEO spam, and 99% are not worth reading. BoredReading is a way to read the remaining great blogs that survived the ice age.

To add your favorite blog, please suggest it here! I get emails every day which helps me maintain a high quality selection of blogs!
