Programing Language: Polymorphism, Dispatch, and the Tale of Poly-Tinting http://xahlee.info/comp/programing_language_polymorphism_dispatch.html #lisp #java #JavaScript
in programing, there's this polymorphism, dispatch, milti-dispatch. These, are by-product of computer engineering. Are idiotic concepts. what polymorphism is, is that it's a function f, such that what it does depends on arity (number of arguments) fed to the function, and or depends on the data ...

Web Design, Minimal Window Width of Popular Sites http://xahlee.info/js/web_design_minimum_width.html
Quite annoyed that Google's g+ in past month ( 2012-03-08 ) assume your window size must be quite wide. Meaning: the page is designed to assume a minimal display width as optimal. For example, if your window is not that wide, part of page on the right side won't show.

How Fast Does Internet Speed Grow? http://xahlee.info/comp/bandwidth.html
Since 1990, hard disk storage capacity doubles in about every 1 year, computing speed doubles by about every 2 years. What about internet speed? How Fast Net Speed Grow? It's about 50% faster per year. The formula is c*1.5^n where n is number of years, and c is a constant.

google plus, finally declares itself a flop. I think, this year, traffic on g+ is even smaller than last year. i thought perhaps it's just my circle, but looking at some public communities, or look at personal popular persons, it seems true in general.

since g+ started some 4 years ago, lots of hype, pain, info, hysteria, we have gone thru, and time wasted. The nym war ebb and flow... then, g+ user interface kept changing. y'know, there's many helpful g+ forums or persons that exist, each time g+ UI changed, these guys went head over hills telling us new features, keys, ways to use, but half a year later, it's all changed. The security, settings, config, also changed. Circles, preferences, public or not... not just the UI, but features, and it's stance, relation to other social networks, its meaning for us, etc. Each month or a few, there are perhaps hundreds or thousands articles written about these changes for us to go over... then, remember g+ games? that came with a splash and went away quietly... then, last year, the g+ head, a biggy at google, quit, which spelled the first sign that g+'s not well... and, remember the youtube integration, the picasa merge, and all the shit and bit went with them.

when you think about it, for those of us who follow tech, it's kinda all time wasted... well, as wasted as any of the so called social networks are. A better name is perhaps online social network browser destination ahaha.

it's interesting, there are still people, in usa, who never much heard of twitter or facebook or refused to ever use social networks. Yeah, those exist, and good for them.

as a human animal watcher, it's quite interesting to observe how things have changed, how things are, and how it will be.

if you haven't heard, g+ is going to kinda be split and gradually wane down. google adamantly claims g+ is not going away, but such a claim already says a ton.

#JavaScript How to Find Screen/Window/Viewport Width http://xahlee.info/js/js_viewport_dimension.html
The result is in CSS pixels. 〔➤ What's a CSS Pixel?〕 The result includes the scroll bars, but does not include the URL field, tool bar, status bar, etc. Note: when user zooms in, these values decrease. Similarly when zoom out. (on desktop, try maximize window, and try go into full screen ...

looking at Logitech G502 Proteus again. Design analysis. Xah's verdict: no buy.
http://xahlee.info/kbd/logitech_g502_proteus_mouse.html
the G502 came out on 2014-04. logitech g502 mouse 2 “Logitech G502 Proteus mouse” amazon. Xah's Verdict: no buy. Why? because: Only 5 real usable extra buttons. Not enough. Compared to mouses of the same class. 〔➤ Why You Need 7 Buttons Mouse?〕 Metalic mouse wheel. Slippery.

the word “formal” in formal proof/grammar/lang, is sloppily used. Most people mean “rigorous”. It should mean: in a form of math formulas.

《Code Complete: A Practical Handbook of Software Construction, Second Edition》 2004 amazon. This i read parts in 1990s. Don't recall much about it except that this is about the only science based appoarch on the questions of software engineering methodoligy questions. Am taking a look again.
