It's now been 4 days since @BSidesCapeTown and I'm still tired. And I'm on day 2 of a migraine. I don't regret going though. It was a highlight of my year. I knew this would be my last one, and I thoroughly enjoyed myself, staying from just before 9am until after 7pm.

Competition has been fierce in this year's CTF. Glad my tired old brain still managed to make a decent showing though. @BSidesCapeTown

I had a wonderful day at @BSidesCapeTown today. There were so many interesting talks, and it was great to see everyone again after the break. Getting to meet @jaysonstreet was probably the highlight of my day.
I'm hoping I can help out at next year's conference.
I had an amazing time today working stations via #QO100 today. I managed to make 3 contacts. Paris, Bletchley Park, and Austria. Thank you to Chris ZS1CDG for bringing his equipment over for me to play with.

ALT Una, ZS1UNA, communicating with radio amateurs in Europe via the QO100 geostationary satellite from Cape Town, South Africa. On the left is an 80cm offset dish with a "Patch of the year" antenna. In the foreground is a table full of radio gear. For transmit: a Yaesu FT817 going into a DX Patrol upconverter and a cheep amplifier. On the receive side was an Icom IC-R8500. All was powered by a 12V Lead acid gel battery.

With Twitter's change in ownership last week, I'm probably in the clear to talk about the most unethical thing I was asked to build while working at Twitter.

When you buy a company, lots of things come in the package, but three things really stand out: the IP, the staff, and the hopeful loyalty of the customers.
Lets look at how Elon's botching all of it.

Daily reminder that a vial of insulin keeps me alive for a week and, in the US, costs the same as an Xbox Series S. Imagine being forced to buy an Xbox every single week for the rest of your life in order to not die.
This is reality for 7 million insulin dependent Americans.
