summary: "This August, I accomplished what I wanted for many years: I deleted the last cgo dependency in Debian Code Search! This was made possible by Go’s recently introduced SIMD support, because now we can implement the TurboPFor integer compression format as efficiently — more efficiently, in fact, by using the newer AVX512 instruction set! — as the reference implementation."

## Summary

This August, I accomplished what I wanted for many years: I deleted the last cgo dependency in Debian Code Search\! This was made possible by Go’s recently introduced SIMD support, because now we can implement the TurboPFor integer compression format as efficiently — more efficiently, in fact, by using the newer AVX512 instruction set\! — as the reference implementation\.
