I have it on good authority and a lot of data that over 40% of deceased drivers in vehicle crashes test positive for recently having (i) breathed air containing oxygen, (ii) drank tap water (iii) were wearing shoes, (iv) had used those shoes to get to the car, ...

As I read the post by MrAlex94, I noticed a remark that the browser Chrome is good as a user agent. To me, that's terrific! Looks like I'll have to consider Chrome again.`

Here are what I find as reasons to scream about Mozilla:

Popups:

(a) Several times a day, my attention and concentration get interrupted by, for me, the unwelcome announcement that there is a new version I can download. A new version can have changes I don't like and genuine bugs. Sure, I could keep a copy of my favorite version from history, but that is system management mud wrestling and interruption of my work.

(b) Now I get told several times a day that my computer and cell phone can share access to a Web page. In this action Mozilla covers up what that page was showing I wanted it to show. No thanks. When I'm at my computer, AMD 8 core processor, all my files and software tools, and 1 Gbps optical fiber connection to the Internet and looking at a Web page, I want nothing to do with a cell phone's presentation of a, that, Web page.

(c) Some URLs are a dozen lines long and Mozilla finds ways to present such URLs with all their lines and pursue clearly their main objective -- cover up the desired content.

Mozilla needs to make their covering up, changing, the screen optional or just eliminated.

Want me to donate? You've mentioned as little as $10. Deal: Raise the $10 by a factor of 5 AND quit covering up my content and interrupting my work, and we've got a deal.

> Not enough time for evolution to respond

And we have to guess that evolution didn't "respond".

Sooooo, we have some lack of fit, evolved over 10s of thousands of years for life as it was then and for the last ~5000 years in selected cultures faced with something quite different, powerful governments and armies, metals, weapons, tools, sailing ships, agriculture, domestic animals, ....

Supposedly for those 10s of thousands of years in parts of Europe people formed tribes and had some communal living, that is, in a long house, maybe 50-100 yards long 10-20 yards wide, with walls and roof forming a semi-circle. So, women and children got their socialization, security, lessons, skills, not merely from a couple, a bonded husband and wife living just as a couple, but from the tribe as a whole. I.e., now, for a lot for a person to learn and have, including shelter, we are depending heavily just on the mother and father.

In a Markov stochastic process, the past and the future are conditionally independent given the present.

Glanced at the exercises. It appears that two of them have numbers arranged in a triangle and ask for a longest path.

Hmm. Given such a triangle, let m be the largest number in the triangle. For each x in the triangle, replace it with m - x. For the resulting triangle, solve it to give the shortest path using one of the well known network shortest path algorithms.

A one word explanation from the T.J. Watson Research lab in Yorktown Heights: "Luster".

One reason for appearing smart is to be terrified of something and work every waking moment to defend against the "something". So such a person can be desperately unhappy, and at some random setback give up everything.

As I was being interviewed by an IBM branch manager in Chicago (my wife had started grad school at the University of Chicago), it was explained to me:

"Some people think that IBM is a technology company or a computer company. It's not. IBM is marketing company. IBM would be in the grocery business if they thought there was any money in it."

Such a cube, i.e., a set, is closed, right? Sooo, there exists a function on the space that is 0 on the cube, strictly positive otherwise, and infinitely differentiable.

For garbage collection and the idea of assigning storage requests to different categories of (dynamic) storage ....

Apparently part of the algorithm is based on the size of the storage being requested.

Hmm. So, we have historical data of storage requests and for each (i) the size of the request, (ii) how long until the storage is freed, (iii) etc. ....

Guessing about a bizarre case: It might be that on Monday many storage requests of certain small sizes have lifetime just a little longer than the decision to move the request to another category, i.e., the moving effort was inefficient, wasted.

So, in simple terms, for an optimization, for each of the variables have both in the history and real time, make the variable values discrete, altogether may have for some positive integer n a few thousand different n-tuples of variable values; then for each n-tuple pick the best decisions (policies, etc.). Uh, unless this idea has already been tried.

> ridiculously tiny and fragile my little life

Naw!!! We are rare, so rare that we might be unique in our solar system, galaxy! We don't look little and instead the reason for the whole show! "Where is everybody?" -- easy, we're it. Soooo, what's the reason??

The whole event is likely to be an exponential, and the last, ah, after Newton, Maxwell, Einstein, Schrödinger, biochemistry, ..., computers, we look like we're at -- a standard for exponential growth, e.g., the question P v NP -- the unique big turn up out of the atmosphere ... blowing past Andromeda at 0.5 c and accelerating.

> Good research is just a vehicle for producing knowledge and talent.

Yup, it was surprise seeing that once have a good STEM field Ph.D., written a lot of STEM and (early) AI software, and have published some peer-reviewed papers, are then condemned as in a felony conviction from ever having money enough to buy a house or to participate in the real world. A surprise.

But so far have missed the law that actually forbids doing some good math research, writing corresponding software, starting an LLC business as a sole proprietor, self-hosting a related Web site, getting users, running ads, and making (oops, forgive the transgression of mentioning) MONEY. Horrors! Uh, that's actually the same kind of "money" that people selling food, clothing, cars, and houses and providing medical care, private K-college education talk about.

Gee, cut out a lot of middle stuff, i.e., save on management, lawyers, office space, recruiting, HR legal issues, insurance, utilities, software developers, cloud fees, server farm staff, servers (an AMD FX 8350 can send a lot of the Web pages with still image banner ads), ....

Just now evaluating Macrium Reflect. Anyone have any experience? Uh, will it copy a disk partition that has a bootable instance of Windows so that the target disk partition will also be bootable or will it copy only whole hard disks with all the partitions, ....???? Similarly for Acronis and Windows Image. E.g., if make an Image of a bootable partition, will the partition written to boot? Right, just use the TIFO method!

It can appear that some famous companies pursue pure research as a source of public luster.

> random delay

A Poison process. Just specify the expected value. E.g., if the expected value is 5 seconds and have gone some hours without an event, then the expected time is still 5 seconds.

E.g., like the time to some radio active delay and whatever its expected value to decay is.

Likely are also making a probabilistic independence assumption.
