Hm, friends, what is your use case for SIMD in #golang ?

Yay, #golang performance dashboard https://perf.golang.org/dashboard/

Cool ARM NEON thread.

Go generics are not bad

When programming, we often need to write ‘generic’ functions where the exact data type is not important. For example, you might want to write a simple function that sums up numbers. Go lacked this notion until recently, but it was recently added (as of version 1.18). So I took it out for a spin. In Java, generics work well enough as long as you need “generic” containers (arrays, maps), and as long as stick with functional idioms. But Java will not let me code the way I would prefer. Here is how I would write a function that sums up numbers: int sum(int[] v) { int summer = 0; for(int k = 0; k < v.length; k++) { summer += v[k]; } return summer; } What if I need to support various number types? Then I would like to write the following generic function, but Java won’t let me. // this Java code won't compile static T sum(T[] v) { T summer = 0; for(int k = 0; k < v.length; k++) { summer += v[k]; }…

One more step to the better #golang benchmarks (now by twitter.com/mknyswe, also accepted 😉):
