Benchmarking Leiningen on Apple Silicon

Gene was tweeting about Clojure's startup performance on Apple Silicon, so I decided to benchmark my new MacBook Air with the M1 chip against my Intel based MacBook Pro.

TL;DR

The M1 chip in the MacBook Air - which lacks a fan - was able to quite tidily beat an almost top-of-the-line Intel chip.

gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

ffmpeg
- macOS: brew install ffmpeg
- Ubuntu/Debian: apt install ffmpeg

Preferences

All preferences for the DNS-over-HTTPS functionality in Firefox are located under the "network.trr" prefix (TRR == Trusted Recursive Resolver). The support for these are targeted for shipping in release Firefox 62.

network.trr.mode

set which resolver mode you want.

0 - Off (default). use standard native resolving only (don't use TRR at all)

1 - Race native against TRR. Do them both in parallel and go with the one that returns a result first.
