Notes

And prior to Apple Airport firmware 7.9.1 (2019), even if you did a factory reset of the device, your configuration was still kept on it but just made inactive.

You could factory reset one, enable SSH, then login and see the previous configuration which would include the WiFi network key, any RADIUS authentication credentials, and an Apple ID "infinite authentication token" if "Back to my Mac" was enabled (though I never found out what token allowed access to).

Yeah flight simulators are cool but what about a BIOS simulator

I don't know how I never heard of Station Eleven before this week, but that was a great series

Maybe GPT will replace us after all...

Can you find the bug in this code?

A beige Zip drive for my beige computer

Me: Web browsers and W3C specs are too bloated these days

Also Me: There should be a WordArt CSS spec

It is scary committing in usr.bin/ssh/

"Will this change make me responsible for the next 0-day on most of the ssh servers on the internet?"

MacTCP on my Macintosh Plus has non-configurable DNS-lookup and TCP-open timeouts of 45 seconds.

I like imagining that UDP or SYN packet reaching the router on its 10BASE2 ethernet and then getting queued while the router initializes its modem, dials a phone number, waits while it rings, waits for its PPP login credentials to be verified by the RADIUS server, and then finally sends its queued packet out to the internet, where it gets a reply that is routed back to the Mac after 35 seconds.

I wrote a quick article on how to take a better scanline-free photo of a CRT screen with a phone:

Through the Looking Glass (1984)

Whenever I see my Framework laptop collecting dust in the closet and think "I should use this more", I start typing on it and immediately remember that the obnoxious lid wobble is the biggest reason why I don't use it.

I upgraded the lid to the CNC version but it didn't help any. Framework says the stronger hinges actually make the wobble worse so I'm avoiding those.

I wish they would figure out how to eliminate that like other vendors have.

I finished cleaning and restoring these blue guys

I like the authenticity and weight of the mediterranean blue 2500 (on the right) but the ringer is so loud even on its quietest setting

The AT&T 100 feels kind of cheap but its digital ringer has a very 80s feel and the blue matches my office nicely
