TIL jq

From GitHub’s We updated our RSA SSH host key TIL about jq - commandline JSON processor.

``` jq can transform JSON in various ways, by selecting, iterating, reducing and otherwise mangling JSON documents. For instance, running the command jq ´map(.price) | add´ will take an array of JSON objects as input and return the sum of their “price” fields.

Hung a bit in Apple Swift issue #55222 SIMD generates bad code for string processing use-cases looking on Godbolt for generated code. It’s really looks bad. Would be interesting for experimenting if this code is faster then no-SIMD code.
