Long live free software!
Last week I gave a workshop on Markdown, the lightweight markup language used for writing for the web (the S5 presentation is available for download). The Open Source text editor I recommended for the Macintosh was Smultron.
Last week I was also using PortableApps.com to view images on a restricted-access Windows machine. The software I used was Cornice, a cross-platform image viewer written in Python.
Both projects, IMHO, are immensely useful (why is there such a dearth of fast, compact and stable Open Source image viewers?!). Both projects are no longer actively maintained. This is sad news. The good news is that because the source code is open, anyone else is free to take the code and develop it further.
Here’s hoping someone does that soon.
