1. If you name your script with the extension .user.js it is easier to click on to automatically install at least with tampermonkey. 2. When I went to this link from the main page, on mobile I had to scroll to the right to see the (-) to minimize because the sidebar was too large: https://elizabethtai.com/2026/06/10/substack-writers-you-nee... It may make some sense to start minimized so I can read the article first, but I can easily modify the script to do that.
They do give Leonardo a lot of credit for a single sentence, but it may be the first documented instance of this charring technique.
I found that Node 22 had ~50ms slower coldstarts than Node 20. This is because the AWS Javascript V3 SDK loads the http request library which became much heavier in Node 22. This happens on the newly released Node 24 as well.
I recommend that if you are trying to benchmark coldstarts on Lambda, you measure latency from a client as well. The Init Duration in the logs doesn't include things like decrypting environment variables which adds ~20ms and other overhead like pulling the function code from S3. The impact of this manifests when comparing runtimes like llrt to Node, the Init Duration is faster than Node, but the E2E time from the client is actually closer because the llrt bundle size is 4-5MB larger than Node.
It doesn't support loading content from a database that I'm aware of, it uses markdown files on disk as input.
