       @jamey @benjamingeer @unnick At a time, I was using echo (and discard) a lot. Every Cisco router had them. https://framagit.org/bortzmeyer/echoping

       @jamey @benjamingeer @unnick This resurrects an old technique, used on ENIAC https://en.wikipedia.org/wiki/Delay-line_memory

       @bortzmeyer @jamey @benjamingeer @unnick Isn't modern DRAM essentially the same, but with a faster refresh frequency and a bit of error checking?

       @expiredtoken @jamey @benjamingeer @unnick No, because, unlike delay-line, it does not rely on the limit of the speed of light. Modern DRAM would work as well with an infinite speed of light.
