The human-powered handcart is the oldest of vehicles, and it will likely be the last one around in the future. Of all vehicles, it’s the cheapest and least complex to build and use. It offers a large advantage over carrying a load on your back or dragging it over the ground - the even older concept of the sled. On the other hand, the handcart is cheaper and easier to use than the ...
The VAX architecture had a simple exception model with traps and faults, but the kernel had to skip the instruction in case of a fault to prevent a signal loop, which was not possible due to the hardware design. A fix was implemented in 2002 to add a skip_opcode function to compute the address of the next opcode, effectively skipping the offending instruction, and it was later carried over to OpenBSD.
