This 40-year-old Microsoft Excel rival is making a surprising comeback

Lotus-1-2-3, an ancient spreadsheet (opens in new tab) program from Lotus Software (and later IBM), has been ported to a new operating system.

As reported by The Register, a Lotus 1-2-3 enthusiast called Tavis Ormandy (who is also a bug-hunter for Google Project Zero), managed to successfully port the program onto Linux, which seems to be quite the feat of reverse engineering.
