One of the most Hacker News articles ever written. A bad solution (wearing a choker) to a self-generated problem (using Arch) that costs a lot of money. In summary: this generates more problems than it solves (unless you're a navy seal).

If you can find some that are wireless and are crescent (so not fully closed) maybe that would be safer!
