I have the new iPhone 11 Pro. It's a great camera. Turns out all of the photos I've taken so far have had incorrect EXIF Orientation data. This really sucks. I've confirmed the same issue happens on my wife's phone.

Generating DDNS TSIG Keys for BIND
The tutorials on how to generate TSIG keys for BIND DDNS updates suck. It would also be tedious if tasked to generate several. I'm not sure why ISC has not produced a standalone script or utility to make this easier as nobody should have to piece it together by hand …read more
