Once upon a time, someone said about Unix regular expressions that if you think can can use them to solve a problem, now you have two problems. What he meant is that regexes are at the same time so powerful and so complicated that they’re hard to debug and hard to be sure that you know what they’re really doing. I feel that way about dremels.


I use the dremel to cut stuff, like plastic boxes, and in this case, a seriously overspec’d steel motor mount I’m using to fix a stepper motor in a little box to create an animatronic tail for my ❤.

But whenever I get the dremel going, I feel like it’s within an instant of flying to pieces, maiming me, and more importantly, like it might damage whatever I’m cutting. A safety course might be helpful, someday.
