Not to mention the 250 that were actually fired and replaced by H-1Bs in January, well before the linked story happened.

I find the close icon on the browser tab to be effective in those cases.
About 20 years ago I did some contract work for a hospital whose accounting group did all of their day-to-day work with Quattro Pro, then a nightly process batched all of the spreadsheet work into the actual accounting system that ran on a System/390. The spreadsheet was useful for the bookkeepers and accountants to get a lot of work done every day spanning 60K accounts, and having the batch run by the actual accounting system was great for picking up errors (the batching code also did some rudimentary checking of its own as well), so we rarely had any errors that took more than a day to identify and fix.
Or push cars driven by idiots out of the way with the truck if they refuse to yield. I watched a hook & ladder truck do that one time at an intersection in Norfolk, VA.
Hmm, how does one see a 50nm virus when illuminated with 400 nm light, no matter how good the lens is?
