I may be misunderstanding the question but that should be just decompressing gzip & compressing with something better like zstd (and saving the gzip options to compress it back), however it won't avoid compressing and decompressing gzip.
Does refactoring mean moving things around for people? Why don't you use your IDE for this, it already handles fixing imports (or use find-replace) and it's faster and deterministic.
Do you know about other security issues? If it's only about curl | sh it really isn't a problem, if the same website showed you a hash to check the file then the hash would be compromised at the same time as the file, and with a package manager you still end up executing code from the author that is free to download and execute anything else. Most package managers don't add security.
Yes for parakeet, but only comparing benchmark results for canary. Whisper also has severe hallucinations on silence and noise and WhisperX helps a lot, it adds voice activity detection i.e. a model to detect when someone speaks, to filter the input before running whisper. https://github.com/m-bain/whisperX
No, you never compute individual pixels because you never need to, and it's always faster to it in bulk (vectorization, memory access...) and so over an area you take the same number of pixels as input (or a little bit more with padding) and the blur will only increase significantly the compute.
This seems to be exclusive to Safari, I can't get it to work in Chrome either (and didn't know about the feature before right now, the discoverability is terrible).
