Comment It's a complete nonsense. (Score 2) 222

Leibniz' notation is normally treated as a "suggestive kind", never to be understood literally. The origin of notation d^2/dx^2 goes from applying d/dx to d/dx, but d/dx only means "a derivative w.r.t. x" and nothing else. Sometime taking this notation literally and doing manipulations as if it were the regular fractions work (and that's b.t.w. is attributed to the early discoveries of many differentiation and integration rules), but it doesn't work most of the time. Any decent book on Calculus should point out that fact. Working with fractions helps to discover some rules, yes, but it's never rigorous, it's more like discovering something in a heuristic way, but then you still need a rigorous proof and that involves going back to basic definition of limits, not arguing in terms of "infinitesimals" (yes, I'm aware of Robinson's "non-standard calculus", but IMHO it's not a mainstream approach. Cheers.

Comment Separate, but some additions. (Score 1) 156

I don't see any reason why Apple doesn't add the touch screen display to its line of laptops with MacOS. It will simply give a user more flexibility. Every once in a while touch screen is natural to use.

Likewise, there is no reason why Apple doesn't add a mouse/touchpad support for IOS. Primarily for use with add-on keyboard. When you use a detachable keyboard with Ipad, it is more natural to use a mouse pad rather than moving your fingers from the keyboard to display. Yeah, I know, they are keyboard shortcuts to navigate the display, that's not as intuitive as using the mousepad for that purpose.

Comment what is a set of instructions? (Score 2) 87

One may argue that at this point it is a simply of specification of interface interpreted by microcode, and interface is not covered by IP, at least every USA court of law rejected any such case. In case of instruction set what matters is its implementation on a microcode level, and of course Qualcomm would implemented it in a way completely independent from the way Intel does. IMHO, Intel would have a hard time proving it otherwise.

Comment Something other than hate ... (Score 1) 374

I agree that there are some folks who hate anything mainstream. But seriously, there are some rationale to be negative about Mir. Don't want to beat a dead horse, but there's absolutely no reason but "not invented here" syndrome for the existence of Mir in the first place. Fortunately, it seems like for the cases like this natural selection works quite well. OpenOffice isn't quite dead yet, but it surely smells funny. Xemacs, RIP. My gut feeling is that Mir may end up exactly like those two. I'm sure there are more examples of that. And, while we're at that, someone mentioned Perl vs Python. As a person who had to main large Perl-based system, many years ago, I came to the conclusion that Perl was written by geeks and for geeks, with very little concern for requirements of production environment where maintainability of a code is a key. Perl exists solely so geeks can have fun writing a code no one else can read. And that's exactly why Python is becoming a standard script for the large production system, and I wouldn't care less about the "evil white space".
