Comment: Speed is indeed important (Score 1) 6 6

Not everyone has a brand-new computer; The manuscript of the book I'm about to publish is in Open Office Word, about 400 pages and full of large images, and autosave is a real pain because it takes minutes to save the file.

Like another commenter said, I wouldn't make it the most important thing, overall efficiency is. But software speed is important to anyone with an older computer, especially a Windows computer, because the computer slows as the registry grows, and the registry never gets smaller, only bigger.

I am not concerning myself with representations of mathematical values, except to show the parallels of why it works. IEEE 754 defines a positive and negative infinity, because it has a specific signed bit. Thus, it's easier to define a positive and negative infinity than to produce special code to handle "exceptions"... note also that IEEE 754 defines a positive and negative 0 separately. No, they really do.

My model is a theoretical one that hasn't reached mathematical consensus, and it likely never will. I just note that this is an argument for infinity being signless.

More importantly is what happens when you graph it: the limit of 1/x as x approaches zero is discontiguous. It's positive infinity when descending on the positive numbers, but negative infinity when ascending from the negatives. No one value can represent both!

Let's assume that the set of integers is Z_\inf. K? We can now define negative numbers as the 1's compliment of the number plus 1. 1 = 999...9998. then plus 1 = 999...9999. This plus 1 results in an infinite carry out, and the value 0. Awesome.

Now, let's look at 1/0, we see that from the right it's approaching \inf from the bottom, while we see that from the left, it's approaching \inf from the top. Now, at 0, obviously these two will be coincident, because we're working in Z_\inf, that value is the same value. Namely, -\inf = \inf. But that doesn't make sense, only 0 can be it's own negative!

But we've already known for a long time about Z_n where n is even, -(-128) in Z_256 is -128. -(-65536) in Z_2^16 = -65536. So, there's no trouble in making -\inf = \inf ...

Basically, 1/0 grows so fast that it manages to wrap around the entire infinite series of numbers. Which is exactly what it does...

That is simply false. There are an infinite number of algorithms that might contain the (sub)expression X/X for which zero is a valid value of X. To assume it's a programming error is sheer unmitigated stupidity that I might expect from a mathematician that has never written a real program in his life.

Dude... you perhaps haven't heard, but computers run entirely upon theoretical mathematics... I know, it's popular to say it's engineering, rather than mathematics, but it's mathematics. It's always been mathematics.

Journal: Number Five 2 2

I just sent off for the fifth and, I hope, last pre-publication copy of Yesterday's Tomorrows. I was sure it would be finished a month ago, but there were problems printing it due to some of the illustrations being too high of a resolution. It took a month to get the fourth printed.

Most, I hate the Sparta icon... it's white, with no contrast border... which makes everything that is assigned to it being the default program, show a white globe on a white background... it's like, "way to go, Microsoft!" followed by a slow clap.

"clean" "modern" design... which will never work decently on all backgrounds... you know... like good logos, and designs...

I agree he doesn't belong on that list. I do think on the list of America's worst presidents, he'd be at the top of the list.

Ignored warnings from the previous administration, top FBI officials ignored field agents who were warning of something bad, and got our country attacked.

Then he started an incredibly stupid war in Iraq, which led to the rise of ISIS.

Presided over the building of mass surveillance of the American people.

Took office during a boom, left office under the worst economy since the great depression. It's my theory that what caused the ruined economy was fuel prices more than quadrupling during his reign. Buy gas to get to work, or pay the mortgage? Tough choice!

Took office with a balanced budget, left it with the largest deficit in American history. Meanwhile, infrastructure was crumbling and he did nothing.

Now, if the list was of people who did the most harm to our country, he should be on that list. Mao and Pol Pot were very evil men who killed millions of people, but they didn't harm America.

Ever since they changed it so I have a goddamned horizontal scroll (are they on crack?) I've only come by occasionally to look at journals.

Look, Dumbass Holdings Idiots, there's no reason whatever short of GROSS incompetence to introduce a horizontal scroll on a widescreen format notebook!! I'm all for hiring the handicapped, but you don't hire Ray Charles to be a bus driver and you don't hire the educationally handicapped to code...

Although I suspect it may be retarded PHBs than retarded coders. Someone is obviously VERY stupid. The idiotic mistakes I see should NOT happen at a so-called "nerd" site.

They are called computers simply because computation is the only significant job that has so far been given to them.
