Step 1: get a 60% keyboard
Step 2: don't learn where the "delete" key is
Step 3: change the keycaps so you can't even look at the keyboard to see where it is
Step 4: ???
Step 5: profit!
There's a video going around, shot on a phone of one russian waving their arms, trying to get a military car to stop, because there are mines on the road. The car then hits the person waving their arms, and then (presumably) the mine as the cameraman shouts and the video is very suddenly cut off.
You don't need to measure spoons yes, but I'd rather not dirty a cup, a bowl, a teaspoon and a tablespoon. I'd rather dirty one bowl and zero the weight every time I'm pouring something in.
They're spare parts for when mine fail.
