Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
The comments do not discuss the writing. They sit on threads about ad-blocker memory use, Tor traffic analysis, and high-volume Python HTTP requests, so the posts likely cover those topics.

Each sheet will hold 1E6 lines, or 1000 seconds. Excel works best, because it uses multiple cores. R w…

on “German foreign spy agency BND attacks the anonymity network Tor”Generally its the upper 32k ports that are ephemeral, and if your churn more than that per minute in connections, you'll run into that TIME_WAIT issue. Hacky way to get around that is to enable tcp_tw_reuse which will let you reuse ports, but it can be risky if you get a SYN from the previous connection that happens to lineup with segment number of the current connection (which will close your connection). Shouldn't…
