That's not been true for a very long time. Current MacBook Pro trackpads (i.e. the ones that TFA is about) use one finger tap for left click, two finger tap for right click, two finger drag for scroll, and four-finger drag for some system-wide gestures. The 'Mac mice only have one button' thing is a decade old (and even before that, Macs supported multi-button mice, they just required that UIs be designed to work well with one-button input devices).

Rather, I consider it pretty easy. :-) Just hold down the ALT key, type in the four-digit code for the character you want, then release the ALT key and your character will show up

Is this really what Windows users consider easy? On a Mac, it depends on the keyboard layout, but for me it's alt-2. A cent symbol is alt-4 (dollar is shift-4). Entering a character with an accent is alt-something for the accent and then the letter that it goes on top of. For example, i-umlaut is option-u then i.

If memorising unicode character numbers is your idea of good HCI, then I really hope I never use a program that you've designed.

I'm an anesthesiologist. I put people to sleep for cardiac surgery. My hospital does around 400-500 hearts a year... and we don't kill any dogs.

So maybe I'm not up to date, or things are/were different in research hospitals.

My personal info was based on stories told by my mother, in about the '60s, when she was a special duty RN at the University of Michigan hospital, often handling cardiac recovery.

My favorite was the one where the UofMich hospital cafeteria, which had been purely open seating, established separate rooms for the staff to eat after an incident where patients' families overheard, and were traumatized by, a cardiac surgeon's response to a question. Asked how his operations the previous day had gone (referring to his experimental and/or practice surgery on a collie and another dog), he said "The blonde lived but the old bitch died."

The kids and adopted dogs story was from my wife. The surgeon in question was Dr. Albert Starr in (at least) the '60s through '80s. He was at St. Vincent's and also flew, with his team, to operate at a number of other west coast hospitals, university and otherwise.

No, you wouldn't -- at least, not with any sensible topology.

The way it usually works is like this: You present your Wiegand card to the Wiegand reader, some magic RF resonance happens, and a stream of bits is produced on a wire.

At the other end of this wire, buried deep in the bowels of the building, is a computer (embedded or not) which verifies that your bits are the correct bits. If they are correct, it closes a relay that makes the door open, and (optionally) signals the reader to provide feedback to the user (blinking LED, sound, etc). If they are incorrect bits, it doesn't do anything with the door, and (optionally) provides feedback to that effect (in the form of a blinking LED, sound, dumping poison gas).

Getting access to the data lines at the reader does not magically equate to physical access to the building, except in Hollywood movies and horrifyingly-bad installations (whereby the insecure reader itself does the numeric verification, and/or uses its own internal relay controls the door).

IOW, you can pry the reader off of the wall and twist any wires together that you want..and nothing happens at all except perhaps a blown fuse somewhere upstream and a headache for whoever has to clean up your mess.

A possible solution would be better simulations so that a student can learn by doing. I think it is a very different than working on a cadaver or simulated patient using conventional methods.

You obviously aren't familiar with surgical departments or you wouldn't have missed practice surgeries on live animals.

For instance: a typical cardiac surgeon, shortly before EACH operation on a human patient, does a practice operation of the same procedure on a live dog.

One pediatric cardiac surgeon was much beloved by his patents and their families, because (with parental permission) he would let the kid adopt the practice dog, rather than sending it to be destroyed. The kid would wake up from surgery with the new puppy beside him, with the same bandages, etc. (and a day or so farther along in recovery). The dog having been through the same procedure and having helped save the kid's life even before they met made for very strong owner/pet bonds. (There's always a live, healthy, practice dog. If the dog dies (or is severely damaged) the assumption is that the procedure failed. You DON'T do a procedure on a human if it just killed a dog. You analyze, adjust the procedure, and repeat until success.)

Getting skills up does NOT require, or usually involve, a lot of practice on JUST advanced simulations, cadavers or, live patients. The live patients are just the last step, when the skills are already finely honed, and the animal models provide immediate feedback, real situations, and automatically correct modelling of mammalian life processes.

Not true, Indiana allows deadly force in defense of property, and there is no duty to retreat. And it includes your vehicle when away from home.


I think you're talking about Indiana's Castle Doctrine law, which gives you the right to assume that you're threatened with death if someone breaks into your house or car (some states also include place of business). But the authorization is for self-defense, not defense of property. The Castle Doctrine just means that the law automatically assumes that you were at risk of death or serious injury in those locations, and you don't have to justify it.

If a guy is stealing your car, would you just watch him and let him do it? Or, you could threaten him with the gun, but both you and him know that you can't legally pull the trigger? So he continues to steal your car, and you can't do anything at all to defend your property??

I can use non-lethal force. There are lots of options available.

But, no, I will not kill a man to stop him from taking my stuff. I have insurance. The situation changes dramatically if my kid is in the back seat, of course.

Most states allow deadly force for forcible felonies, and include burglary. The rationale there is that the house may not be empty, and so there may be human lives at risk. It's a reasonable choice.

So, in Missouri, not only can you shoot someone for simply breaking into your house while you're home, after January 1, 2017, you can also shoot them in the back as they run away.

This is even more wrong.

Some people manage by the book, even though they don't know who wrote the book or even what book.
