they are switching from Cherry MX switch to Kailh keyboard switch. Kailh keyboard switch is just Cherry MX clones, made by a company in China. see http://deskthority.net/wiki/Kaihua_PG1511_series. I'm guessing it's not that much different from CHERRY MX.

looks like quite a few keyboards are using the Kailh switch. Supposedly, the Cherry MX has supply problems.

they also have some other minor changes. The Shift key is now in conventional position. Ctrl is now at conventional keyboard's CapsLock position. vim and emacs hackers overjoy! The HYPHEN-MINUS - and LOW LINE _ key are now in the middle, replacing the Tab there. The Tab is moved to the upper left corner. And upper right corner has a duplicated Backspace ⌫ key.

Overall, the key layout changes are now more conventional. People really don't wantto change habit. The new layout makes it easier for people to adopt.

computer language: mixed list and hashtable

these days, some lang has array/list and hashtable mixed into one. It is popularized by php.

php started that way probably due to a hack. The lang doesn't have arrays, but what it calls array is a mix of hashtable. When used like array, the keys are automatically filled with 0, 1, 2, etc. [see PHP: Array Basics]

JavaScript is a different story, but also hack and incompetence. It did NOT intent to have mixed array/hashtable, but rather, in order to be simple, it's array is implemented as hashtable (which is its object), so it pretent to be array. [see JavaScript: Understanding JavaScript Array].

nobody liked these, because they are even less than a design decision. The JavaScript here is simply fk'd up.

though, i heard lua is also mixed array/hashtable. Anyone know if it's really good?

The Over Flowing StackOverflow

StackOverflow… although useful, but i hesitate to participate in depth. Like all such forums (except usenet), soon it picks up gazillion policies, rules, and cult communities of the subject, where you can't really express a particular view. And, things like, if you don't use the site in a particular way, the community don't consider you good even if you contribute lots answers (not necessary by a policy, but by the behavior of the members.). And, there's this bunch of badges and score shit. On the surface, they are a bit fun for everyone, but mixedin is really a addiction touch, and of course, the site owners know it precisely, that's why they are there. Its called commercialization.

of course, big congregated sites like that make millions, for themselfs, while the open source fanatic idiots, get nothing, defend the site, yet themselfs work for non open source companies making thousands a month, but has the audacity when some poor sob doesn't open source stuff. fk the open source scums. 'its they, gets us today's web, where most news sites are garbage filled with lurid ads, individuals and creative people get nothing, and we must sing ode to open source. 'tis how communism rose.

IDEOLOGY

Whatever programmers think about themselves and these towering logic-engines we've erected, we're a lot more superstitious than we realize. We tell and retell this collection of unsourced, inaccurate stories about the nature of the world without ever doing the research ourselves, and there's no other word for that but “mythology”.

read and weep. Should Array Index Start at 0 or 1?
