At a previous job they tracked down some slow https performance in a game server to OpenSSL lib allocating/reallocation new buffers for each zip’d request. Patching that gave a huge performance increase and saved them from buying some fancy $500k hardware to offload the https processing.
I bought my wife a Liv electric mtb (front suspension only since it was cheapest). She never rode mtb before this and now 6mo later she's an almost daily rider. We live at the base of a large mountain range with lots of trails and the electric assist has allowed her to gradually build up the endurance to ride the mountains. Soon she'll be transitioning to a non-electric full suspension and we'll probably sell the electric.
