Python 3.11 Runtime Now Available in AWS Lambda — Amazon’s maintenance of its Lambda runtimes has come under scrutiny in the past year, but Python gets a little TLC with this upgrade. You can now build and deploy functions using Python 3.11 using all the usual mechanisms, or use the Python 3.11 container base image if you prefer that approach. As well as pushing out the EOL horizon, Python 3.11 is also around 25% faster than 3.10 so you may save a few milliseconds here and there too.

▶  SST Explained in 100 Seconds — According to a recently-concluded multi-year study, the average amount of time devoted to any written article is a shade over 72 seconds. For about that amount of time (plus a bit, of course) you can learn everything you really need to know about SST, a framework for building full-stack apps using serverless AWS technologies.
