Items of the week

  • GitHub Action - there can be up to 256 jobs per workflow run using a job matrix. One example use case is to run with multiple versions of Node.js, as pointed out by the official GitHub Docs webpage.

  • AWS Lambda - we could create aliases for Lambda functions, an alias has its own ARN and points to specific version of a function. One use case is to set up production and staging aliases that points to different versions of a function, got this from chapter 6 of Serverless Architectures on AWS.

  • On the week 44 of 2021, we saw the release of Intel’s 12th generation Core processors known as Alder Lake, one of the highlights is that it’s a hybrid architecture with both performance cores and efficiency cores. AnandTech has a detailed review on this.

A little note

Another small change in the post format, of the three weekly items, one will be from an online source, like an article or a Tweet, while another one will be from a book or a paper, and to mix things up a little, the third item will be a bit of a wild card, probably something new from that week. That’s all for this week’s post, thank you for reading and have a nice day!
