It's odd to realize that exactly 50 years ago, my mother took me to my first day at school. Happy belated birthday, younger me! Now go and buy shares in a newly-formed startup named Microsoft!

I can confirm it's true - AI is making me lazy and not wanting to think too hard about writing code. I had a moment of panic today when GitHub Copilot stopped auto-completing my code, and I was forced to remember the syntax I needed. Turns out my "free credits" expired.

We're so excited to finally get to share some BIG updates!

First, AWS Toolkit for VS Code can now connect to LocalStack making it easy to build, debug & test Lambdas directly from your local machine without leaving the comfort of your IDE! Read our tutorial: blog.localstack.cloud/aws-toolkit-...

Serverless developers, I'm excited to see this collaboration between LocalStack and the AWS Lambda team. You can now use AWS Toolkit for VSCode with LocalStack, complete with Lambda Debugging, making even easier to develop, debug, and test your applications locally!

Without even realizing it, I’ve been using GitHub Copilot in VS Code, and I love it! ❤️

After several years of being frustrated at coding assistants, I’m finally enjoying the experience and getting a productivity boost! I might even pay $10/month for it!

CloudFront Functions and Lambda@Edge are incredibly useful. The only downside is the difficulty in developing and testing them, as deployments take considerable time, and AWS provides no local testing capabilities.

This has changed with LocalStack.

Hey Step Functions developers - if you need to test your State Machines, and you're sad that Step Functions Local is no longer supported, read my exciting new blog post, then switch to LocalStack instead.
AWS deprecated Step Functions Local, so LocalStack built a drop-in replacement. 💪🏿

If you’ve used Step Functions Local for testing workflows, mocking services, and avoiding side effects… you probably noticed it’s no longer supported by AWS!

First world problems... you try to create an Amazon S3 bucket with a unique name that nobody else in the world would use... but then you realize it's already in use, by yourself at a previous company.

Is it just me, or do other people accidentally open the App Store when they really want VSCode? Perhaps it's just me 😑

With the increase in AI-generated videos, at what point should I stop believing what public figures are saying? Or should I ignore everything on social media and only watch news from the BBC? At this point in time, Doctor Who is feeling quite credible!

Does anybody else feel less miserable when they look at my odometer reading? (terrible joke of the day).

I just drove by the theatre where I watched Star Wars as a boy in 1977. For months after that I dreamed of having my own R2D2 Droid. Now I realize the 50th anniversary is just two years away, but I own an iPhone not an Android.

After relocating to New Zealand, there are two important things I miss from Canada. 1) Central heating, 2) Tim Hortons Sausage BELT with Steeped Tea.

But what's really sad is that after eating 100s of Sausage BELTs, I don't have a single photo of those delicious sandwiches! Just one of this cup 😑

Product idea? The “change of address” feature is not a solved problem. After my recent international move, I had 30 places to give my new address to. About 20 were simple online profile updates, but 10 required support calls/tickets. And 4 of those required multiple tickets to the “backend” team!

Tired of waiting on IAM tickets or racking up surprise AWS bills?

@jetbrains.com shows how to build & test a full Spring Boot app with S3 + SQS locally using LocalStack + Testcontainers.

Same AWS APIs. No cloud required.

This LocalStack launch is particularly special to me, as we now support the "mocking" feature from Step Functions Local. Now you can use JSONata and Variables (and other recent Step Functions features) with improved testing support!

Another funny UX example, this time from Rakuten Viber. The $4.99 worth of credits can be purchased for the low price of $7.99. As far as I can tell, the first $ is USD and the other $ is NZD. 🤦

Super-useful hint I learned from The CDK Book. When using CDK with TypeScript, always run with "npx cdk synth" to use the version of CDK from your project, rather than defaulting to your global CDK.
