AWS open source news and updates No. 28

July 13th - Instalment #28

Week No.28, and this week we have another fantastic collection of open source posts covering robotics, containers, serverless, machine learning and more. I cover a number of projects you can get stuck into, including robotics projects and resources, a continuous machine learning project posts and the usual collection of indispensable projects that you will wonder how you ever managed without. Finally there are some events you might want to put in your diary.

Remember, if you have a project you want me to mention or talk about, then please reach out. I do provide prizes for the ones that I particularly like, so there is also that incentive too.

Super excited this week about the Open source builder videos and blog posts that we released late last week. It was a lot of fun talking with Olaf, Alex and Liz, all of whom have featured in past episodes of this newsletter, either because of open source projects they are behind or open source products they have launched.

Part one is all about how they got started in open source, and we follow that up in part two with lessons learnt. Now I have to apologise that there is no video of Liz and this is entirely my fault. During the recording of these sessions, I had a complete fail and whilst I recorded the video, there was no audio. Very sad, as it was an epic session.

If you want to take part then please contact me as I am currently organising recording of the next batch.

Looking for a project to join?

Adam Crockett is a developer who has been documenting his journey in creating a new open source project called didi. You should definitely check out his posts as I think you will all learning something and I really love how Adam is building in the open and sharing his thoughts and getting help from the community.

In his latest post, Review my open source repository, Adam shares more info about this project and is now looking for more community engagement to help review and participate. So didi is a a transpiler for JavaScript and Typescript, transforming CommonJS modules into distinct ES Modules which front end and Deno developers will hopefully find useful.

Here is to lots of success in your project Adam, and I hope you inspire others to document their path so we can all benefit.
