Ever wondered where the term ‘bug’ came from? Well, on September 9, 1945, U.S. Navy officer Grace Hopper found a moth between the relays on the Harvard Mark II computer she was working on. In those days computers filled (large) rooms and the warmth of the internal components attracted moths, flies and other flying creatures. Those creatures then shortened circuits and caused the computer to malfunction.
The term ‘bugs in a computer’ had been used before, but after Grace Hopper wrote in her diary “first actual case of bug being found” the term became really popular, and that’s why we are still using it today.

Yeah, I read that in wiki just now, but I still think it was a new application of an old word

TIL: Japan had issues with crow nests on electric infrastructure, so they went and destroyed all of the nests....which prompted the local crow population to just build MORE nests, far in excess to what they actually needed.1

Is a crow a bird of prey or are they just scavengers and is there much of a difference and if I built an electric infrastructure in my yard will it attract crows to build nests there and do they eat moles?
The American crow is omnivorous. It will feed on invertebrates of all types, carrion, scraps of human food, seeds, eggs and nestlings, stranded fish on the shore and various grains. American crows are active hunters and will prey on mice, frogs, and other small animals. In winter and autumn, the diet of American crows is more dependent on nuts and acorns.
American Crows are very social, sometimes forming flocks in the thousands. Inquisitive and sometimes mischievous, crows are good learners and problem-solvers, often raiding garbage cans and picking over discarded food containers. They’re also aggressive and often chase away larger birds including hawks, owls and herons.
So you don't want crows you want owls and hawks which crows would scare away. You need a good owl tree.2 -

The Aztec word ahuacatl means testicle, which is where the word for avocado comes from and is most likely because of the similar shape and texture. Interestingly, Avocados also act as aphrodisiacs.
