U2F Zero in Firefox
posted March 26, 2018
I recently got a U2F Zero, a tiny (about 2 inches long) and cheap (about 8 dollars) device implementing the FIDO Universal Second Factor protocol. It’s open source, too, which is awesome.
I primarily use Firefox. Unfortunately, Firefox doesn’t support U2F out of the box; you have to enable security.webauth.u2f in about:config.
Once enabled, I tried to register it with GitHub. Unfortunately, it kept on failing, despite the little green light on the U2F Zero going blue.
I Repaired My Headphones

Hardware manufacturers are missing out on a huge potential source of revenue: the thrifty tech user market. No, really. Let me explain.
I just woke up to find that my favorite pair of headphones was making only one sound, and it wasn’t the one I was putting in as an electrical signal. It was rattling.
Feeling adventurous, I popped the around-the-ear pads off and - lo and behold! - found four Torx screws.
The Sinclair ZX-81/TS-1000

I recently watched the excellent film Micro Men, about Sir Clive Sinclair, Sinclair Research, Acorn Computers, and the fight for the British low-end computer home computer market in the early 1980s. This, along with a healthy (unhealthy?) dose of procrastination, lead me to spend a few hours browsing eBay, looking for old PCs. “Timex Sinclair 1000 Retro Home Computer, New In Box”. I checked the price - $29.99 plus shipping. It has been one of the most interesting purchases of my life.
