Using Obsidian

https://dev.to/paratron/introducing-and-using-obsidian-3o17

I use and love Obsidian already. It is a great tool to organize content extracted from posts, YouTube and more. And most cool of it is based on Markdown <3. I encourage you to try it!

Update: I figured that VS Code is probably as good as Obsidian for managing your content. Even better you can open multiple tabs in VS Code which you can't in Obsidian.

What is WebAssembly and why it is a game-changer?

https://dev.to/aryank21/what-is-webassembly-and-why-it-is-a-game-changer-21p4

Webassembly or short WASM is super interesting. It advertises developers with execution speed compared to js solutions. For a greenfield project, I definitely want to try it. Super interesting as well is to get potentially closer to the hardware like perhaps IoT devices.

Zero Cold Start for Lambda

https://www.reddit.com/r/aws/comments/ud5fos/zero_cold_start_for_lambda/

Super interesting discussion about zero cold starts for Lambda. That highlights the big conflict like serverless vs zero cold start Lambda. Zero cold starts are possible but not without trade-offs. Sure the customer wants that without trade-offs. That is really hard.

How to speed up Lambda Functions

https://www.freecodecamp.org/news/how-to-speed-up-lambda-functions/

So Lambda hast different phases like init, invoke and shutdown. Initialization code should be put into the init phase which means outside of the lambda handler function.

EKS Blueprints: IaC Modules for Production-Ready Kubernetes

https://itnext.io/eks-blueprints-iac-modules-for-production-ready-kubernetes-48032d5ce88#2ee6-c02bad69ddca

Super summarizing about the new-ish AWS CDK EKS Blueprints. That topic seems very hot and very promising to be a nice abstraction on top of K8S. Unlucky I am more on the serverless-ish side so, I probably miss some cherries atm.

Deploy Serverless Containerized NodeJs Apps on AWS ECS Fargate with AWS Copilot

https://www.serverlessguru.com/blog/deploy-serverless-containerized-nodejs-application-on-aws-ecs-fargate

Good roundup about what is AWS ECS, Fargate and Copilot. It made me curious to learn more about Copilot as it seems to have some cool CI/CD capabilities.

Websocket with React

https://dev.to/koladev/websocket-with-react-nodejs-and-docker-building-a-chat-application-3447

Create a React-based chat using WebSockets. Uses Tailwindcss which is cool.

AWS Amplify Studio

Amazing post about Apollo GraphQL and AppSync. Very cool is that it recommends CDK to do the infrastructure.

https://www.heise.de/news/IT-Spezialistinnen-dringend-gesucht-Unternehmen-hoffen-auf-mehr-Frauen-7066656.html

Great topic about how to get more women in tech. It seems it would be useful to provide young girls earlier with information about IT jobs.
