Weird Brazil Date Bug with Jon Skeet

Digging through my archives once again and found this wonderful video with Jon Skeet doing what he loves to do: sleuthing date bugs and answering questions on StackOverflow!

Back in 2011 or so I recorded a series of videos with Jon Skeet, dissecting answers to his StackOverflow questions that he found interesting.

Jon starts things off by sleuthing out a rather hairy Date/Timezone bug which, evidently, only happens in Brazil. To make matters even more interesting, the code is written in Objective-C on iOS6!

There are a lot of opinions about AI, whether it helps or hinders our coding process and our team in general. Many are concerned that junior devs will be the ones impacted the most.

Following Your Imagination

I learned to play ice hockey when I was 11 and, as a kid from Southern California, it wasn't easy. I learned how to skate and how to play the game at the same time, all while going through a massive growth spurt. My sister once called me a "baby giraffe on a frozen lake". Nice.

It wasn't what you said, but how you said it

I make videos for a living and I swear: each one is an adventure. You would think I would have a system down by now but, as it turns out, each video is a unique thing that demands it's own type of story telling.
