☁️ πŸ“– Learn By Doing Volume 03 πŸ’»πŸ”¨

This week I focused a lot on actually taking a break from technology and coding outside of work. The weather has been fantastic here in Oregon, we get really excited for 80 degree days around here. So when the 🌞 is out I like to take a break from the computer screen and enjoy a beer with some BBQ.

But I couldn't resist sharing volume 3 of this newsletter with you. I am very excited to share that I recently launched the Learn By Doing Newsletter landing page on my site.

Everyone wants to move to serverless because its cheaper and scales on demand. But like everything in life, there is a trade off. Cold starts are that trade off to serverless. You should understand them if you are going to move to a totally serverless architecture.

Stratis Unveils Alpha Release of C# Smart Contracts Blockchain smart contracts are becoming all the rage as of late. It seems like more and more companies want to create their own version of them.
