I was recently a Director at AWS. My org owned EventBridge, Step Functions, SWF, and a few other things that keep the machine moving but which you won’t have heard of. Super interested in Serverless, integration, and developer experience.

Oh wow, I hadn’t heard. I just met up with some folks we worked together with way back and our reminiscences included Ian. So sorry to hear he passed.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

Real-time push notifications can be accomplished using different approaches but using the services mentioned in the video make it quite easy. Tools like Step Functions, Eventbridge, and more are involved. (2/2)

Finally deleted Twitter (I refuse to use the new name) from my phone. I’d stopped paying attention in general, but was still finding my way over there once in a while. Really doesn’t seem to be any good reason to anymore though.

The new Don Ross vocal album Don does his first all-vocal album since 2009, focusing on songs by Canadian songwriters

Don Ross is a Canadian musical legend. He funded his last album through kickstarter and is looking to do it again, but needs help to get this one over the line. This is an awesome way to help an independent artist! Please think about backing.

Huge launch! EventBridge and Step Functions can now invoke APIs deployed inside your VPCs. Building on the VPC Resources over PrivateLink that also went live today. Awesome partnership with these teams to make this happen! Excited for how it will simplify modernization!
