How to update a borrowck test for MIR borrowck

When we fix a bug in MIR borrowck, we often want to update an existing test and show that it does the same thing for MIR and AST borrowck. This gist describes the steps to do it.

compile-fail tests

An example of a test that has been updated to test both MIR and AST borrowck is borrowck-match-already-borrowed.

Flashing an unbranded smart lightbulb to Tasmota

Whilst on holiday last week I thought i would do something productive but that seemed like work so I bought some cheap noname wi-fi smart LED lighbulbs off ebay and flashed them with Tasmota firmware, since the particular bulb I bought wasnt listed on the Tasmota Device Templates Repository and I have no idea if they accept an entry for a bulb with no identifying marks I thought i'd put something here incase its of use to anyone.

Reliability: I have at this point had 10 of these bulbs running for about a week, one of them has just died.

TL;DR

The pinout and device string for this light:

• GPIO4 Cold White PWM 4
