> Even though one could have similar typing style, I doubt that it is always the same on every keyboard.

Several numbers can be used to describe "typing style". Some of those numbers are remarkably consistent.
In other respects, you end up with two profiles, ie John on his iPad" and "John at his desk".
Those match up with other parameters like OS patch lvel, browser version, plugins, etc. You, on your ipad,
type in a certain way, on a certain version of the device, using a certain browser with certain plugins, etc.
Most likely, the identity thief is in a different country, using a different browser on a different patch level, and types differently.
So we can say "John should be either type at about interval 52 iPhone 2 in Idaho on AT&T, or type about 78 on a HP desktop connecting with Comcast, again in Idaho.

> If this authentication system can detect that, it is great; otherwise, it could be a big failure instead.

For Strongbox, this aspect is neither perfect nor a failure, but is one parameter that's considered. Very much like considering someone's height and weight when trying to recognize your spouse. You can see someone from far away and if the height and weight don't match, that's not your spourse. If the height matches, the weight matches, the skin tone matches, the clothing style matches, the hair length matches, the hair color matches, the hair style (curly, straight, etc.) matches, and she says "hey baby", that's probably your spouse.

If you hadn't tried it, you'd think that might be a problem. In fact, it's not.

I've been sick, I've been injured. My COO has been sick a lot. We log in to systems using Strongbox maybe four times per day.
Four times per day times about 400 days = 1600 logins for each of us. We haven't been locked out based on keyboard and mouse yet. Looking at millions of user logins, the keyboard and mouse indicators closely track the other indicators we use. By that, I mean if the real user scores 41-52-07 and they are in the US, when see a log in attempt with a score of 24-92-18 that attempt will come from China.

Different devices really aren't a problem. It's a lot like recognizing your family members while they are wearing different outfits. A twenty-something black lady, pregnant, with medium length braids sitting in my couch is probably my wife. Without my glasses my vision is 20/100 but I could almost always distinguish an intruder vs. my wife. Most likely, an intruder would look nothing at all like my wife.

  That's a good analogy for how we use this type of technology in Strongbox. We start with the fact that they claim to be John or whoever the account holder is. We don't have to identify who they are, just whether or not they look like John. Certain characteristics of his typing style are pretty consistent across different keyboards. We combine that with location, browser choice, etc. to see if the person claiming to be John probably is actually John or not.

"A new record" is false because while the unpublished raw score for the Tesla was 5.4, the same unpublished raw score for the Ford Mustang was 6.2.

Or maybe not. Since it's unpublished, I, you and Elon Must don't know if it's a record high or an A-.

Inverse square would apply if it were radiative (far field) and omnidirectional.
Inductively coupled coils that are also harmonically tuned get the best of both inductive and radiative fields.

>charging would have to be via beamed RF energy instead of magnetic induction.

At low frequencies or short distances they are almost the same thing. "Near field" is within about a wavelength or two, which at 30 Mhz is about 10 meters. So there's not really a hard cut off between induction and RF, more of a large gray area where you can say "this range generally behaves more like an inductor". There's no reason an "inductive" charger can't be tuned for charging devices within six to ten feet - anywhere in the room.

"If this were the case" - if what were the case? If our devices helped us out in those awkward moments?

It is a valuable skill to have. Not all of us have it. Some of us are more skilled in relational calculus. A moment ago, a coworker stopped by my office. We have apparently worked together via email, but never met in person. I had NO idea what we worked on. When she said "thanks for all your help on that" I had no idea what she was talking about. An onscreen reminder of our last email or two would have been welcome.

I saw the sarcastic GP of your post as its parent.

Some commenters seem to be missing the important point that it presents SUGGESTIONS - it doesn't send an automated reply as if it were from you.

The other day I ran into an acquaintance a I hadn't seen in a while. I had not kept in touch, and I don't remember what's going on in other people's lives, anyway, so I had no idea what to say. (Ie "sorry to hear about your mom" or "how do you like the new job?"). Had I heard any news about him and his family lately?

I remarked to my wife that it would be cool if I had something like Google glass with an app that would automatically (and quickly) pull up his last three Facebook posts to give me a clue. Not INSTEAD of genuine human interaction, but to help jump-start a conversation.

Might they move a few hundred meters across city lines to save $4 million X 20 years = $80 million. Yes!

This is very visible where I live, in Bryan / College Station, Texas. A large portion of both cities is within a mile of the border between them. Driving through the area, it's obvious which city has traditionally been friendly to businesses and which hasn't. The College Station side has new towers being built a couple hundred feet from the empty, decaying buildings in Bryan. A few years ago Bryan figured it out and is now attracting new investment. The downtown Bryan area has switched from hookers and gangs to restaurants and boutiques, but most of the city is still suffering from the fact that businesses preferred College Station for so many years.

> You're either trolling, or stupid, not sure which

I take it you're new to planet earth. The post to which you replied is a nice example of what we call "sarcasm".

Two other people did CD changing on YouTube. I don't have anything to add. Maybe one day I'll get a chance to post my DMX lighting stuff. the main thing I can tell you about that is it you do not need the DMX shield. All you need is a MAX485 and the connector.

The court has decided that in order to do their job most effectively, it's best that they give congress a chance to do theirs first. While congress is in the middle of debating the issue, it's counter-productive for SCOTUS to provoke pointless power struggles all the time. See "the chief justice has made his decision, now let him enforce it".

It's quite possible that congress will address the issue and there will be no need for SCOTUS to get in their face. If congress passes something that's not acceptable, SCOTUS has positioned themselves to have the last word.

Are you under the impression that Chrome changes the file associations? All they've done is treat PDF the same way browsers have always treated jpg - as content the browser is able to display natively.

Thanks for the reply. I was thinking that maintenance technicians would need to have access to the system, but you're right, that's not necessary. Assuming the display is separate, a $25 board could be replaced as a unit without increasing cost much, given the cost of the tech's time. That certainly simplifies assuring the customer that the unit hasn't been tampered with.
