What Hacker News says
2 sourcesSecond article I'm reading on implementing this in Go. Since the temperatures are in the range [-99.9, 99.9] with a tenth of precision (~2k values), I am surprised why no one has implemented a parsing of the numbers using a prepopulated lookup table. Should probably speed things up.
I submitted a github issue on this for the other implementation I looked at here[1].
