Hallucigenia

Hallucigenia is a genus of Cambrian xenusiids known from articulated fossils in Burgess Shale-type deposits in Canada and China, and from isolated spines around the world. The generic name reflects the type species' unusual appearance and eccentric history of study; when it was erected as a genus, H. sparsa was reconstructed upside down and back to front. Hallucigenia is now recognized as a "lobopodian worm". It is considered by some to represent an early ancestor of the living velvet worms, although other researchers favour a relationship closer to arthropods.

dongle hell

Dongle Hell is a special type of hell. It is a place where owners of modern apple electronics (Macbook 2017+, iPhone 7+) go to suffer for the rest of eternity to deal with dongles and a multitude of connectors & cables. Due to Apple's lack of physical ports for connections that are still very popular at the time of this writing, June 2017, users are forced to buy dongles and/or cables in order to use their connections that Apple apparently considers "legacy." Dongle hell could entail dongles for aux ports, USB 3.0 and below, SD card slot, HDMI and more.

You got the new Macbook Pro? How's dongle hell been treating you?
