For tracks I’m familiar with and play often, I can usually tell the difference between 128kbps and 192kbps on an MP3. In very rare cases, with the right song and the right earphones, I can discern 192kpbs MP3 from 256kbps. But I definitely can’t tell a 256kbps MP3 from FLAC. The Wikipedia article on audio transparency says that MP3 becomes transparent on average around 240kbps.
I’ve recently started using the Opus codec. It is higher quality at lower bitrates than MP3. Opus is considered transparent on average at around 160-192kbps.
Personally, I’ve been re-encoding all my FLACs to 192kbps OPUS for storing on my smartphone where space is limited.







For those who don’t know the history, Servo was the very first Rust project to ever exist.
Back in 2012, Mozilla knew that their Gecko web engine was already getting old and unmaintainable. One of the engineers in their R&D department Mozilla Research was quietly working on a new programming language, so they adopted that to start work on their new browser engine, Servo.
Rust v1.0 was released to the public in 2015, and was much more popular than the new browser engine it was used to create. Mozilla Research eventually gave up the idea of a new browser engine, but they did merge some of the Servo features into Gecko. Mozilla Research was shut down in 2020, and the Servo project was taken over by the Linux Foundation.
