I worked on a few fairly prominent efforts in open source (Istio, OpenAPI), but I think of all of them, it’s gRPC that I think has the coolest story. Pull up a chair and set for a spell (any inaccuracies in what follows are 100% my fault for having a bad memory!).

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.

🚀 "Wait, JSONata can do WHAT with AWS Step Functions?!" If you use #AWS Step Functions (or want to), these 2 new features—JSONata + Variables—will save you time, money, and sanity. Let’s break it down ⤵️

Had a great livestream with Michael and Ashish on direct integration with private endpoints from Step Functions. Here are a few promised resources. Show: www.youtube.com/live/LqhnA_M... reInvent: - www.youtube.com/watch?v=SRgw... - www.youtube.com/watch?v=9YoK... repo: s12d.com/private-direct

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)

New #AWS Developers Podcast! 🎙️ With Rajesh Pandey, we explore AWS Lambda, event filtering, streaming & Kafka integration. Listen now! 🎧 developers.podcast.g... #Serverless #Lambda

The AWS Developers Podcast is a fantastic listen for all things AWS development by @sebsto.bsky.social. Get info, insights, tips, and updates for devs of all skill levels. Here's a recent one diving deep into Lambda event sources with Rajesh Pandey developers.podcast.go-aws.com/web/episodes...

Ok check it out, if you are interested in getting rid of those proxies when calling private APIs from Step Functions or EventBridge, I made a video -> www.youtube.com/watch?v=gVO5...

Oh Canada!

Nice start to the game

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.

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. emails.kickstarter.com/ss/c/u001.rU...

The #AWS Asia Pacific (Thailand) Region is now open -- learn more at aws.amazon.com/blogs/aws/an... . This is our 14th region in Asia Pacific and our 35th globally, with 5 more regions in the works.

New Year’s Resolution: I will take 2 seconds to unsubscribe to crap my Gmail address (one many others confuse for their own) gets subscribed to, instead of wasting time deleting spam and being grumpy all year.

This was super fun and a bit different. API208 Building an integration strategy for the future with Tom Soderstom (Enterprise Strategist, former CTO of NASA JPL, and 13 year AWS CAB member) and Brian Zambrano (#eda educator extraordinaire) #reinvent #integration #innovation youtu.be/CLBlmazHeIE?...

Want to learn more about the recent #eventbridge and #stepfunctions Private API Integration launch? The presentation Uma, @embano1.mgasch.com, and I made at #reinvent is up! Lots of detail right “from the horse’s mouth”. m.youtube.com/watch?v=9YoK...

Expense report submitted. I am inordinately happy with myself. #reinvent

I wonder if anyone sells collision insurance for walking the halls at #reinvent?

Whoa, this floor is seriously messing with my senses. #reinvent

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!

This year, I will track my expenses as I go, so I don’t have a mess when I get back. For sure this year. I really, really mean it this time. #reinvent

Excited to head for Vegas soon to meet with customers at #reinvent2024! It'll be an awesome week, looking forward to these sessions, connecting with many of you, and having some fun conversations!

Run, don’t walk, to sign up for this one. If I’ve learned one thing in my time at AWS, it’s that when @marcbrooker.bsky.social talks, you want to listen!

I've just built a first stab at an instant converter between JSONPath and JSONata ASL. Still some corner cases missing, but does most of the work. lars.tools/jsonata #aws #stepfunctions

#serverless development with #stepfunctions often involves using #workflowstudio to experiment and refine something new until you're ready to integrate it into your project. That step is now easier to do with export to #sam or #cloudformation aws.amazon.com/about-aws/wh...

It might not be obvious at first glance, but this is a massive improvement. #dynamodb has a learning curve, but it’s worth it. The launch of on-demand a few years ago was a game changer, but it had some sharp edges. From my perspective, this knocks off the last one! aws.amazon.com/blogs/databa...

We love to talk about new features, but it’s awesome to share work on what we call fundamentals. Enormous amount of passion and engineering innovation to drive these #eventbridge latency improvements that open up more use cases for #eventdrivenarchitectures on #aws ! aws.amazon.com/about-aws/wh...

Never gets old

The Test State feature for #stepfunctions is enormously helpful. A few weeks ago, I shared with the team how I wished I could not only copy the value from a node in a test response but also the path (so I can use that in my next state). And now I can! I love the team's focus on reducing pain points!
