Seagate Barracuda 120 SSD 2TB Internal Solid State Drive Buy at amazon

so, solid state drives are getting cheaper and larger. by the way, is this trend gonna continue, or, what's the technology's limit?

a friend says, yes it's gonna continue.

what's the best device for typing? how about gaming? and what is linear programing?

@Anon21 asks: In your opinion what's the most optimal device to type and game on and what is the most optimal video game keybind layout? (WASD, ESDF, TFGH, IJKL etc.)

That's a complex question. There's no one easy answer.

in general, the specifically designed, weird looking devices, are best, for specific task.

For example, what's the best device for typing? If the typing is speech text, then best is probably google voice input. But if we must restrict to finger operated devices and consider ergonomics and speed, then a stenotype [see Stenotype Machine] is probably best, but, that means we are not counting learning time, and practical inconvenience, cuz you don't have a stenotype on every computer.

So in general, there's ergonomics concern, and practicality concern, for example, Steno machine vs normal PC keyboard vs ergo keyboard like kinesis vs average ergo such as Microsoft or generic split mech keyboard. All has pro and cons.

It's like, multiple variables, and the method to solve such problem is called Linear Programing.

That is, you have variables like potential typing speed capability of the device, long term ergonomic consideration (say 2 hours continuous use per day for 3 years) , convenience consideration (how available is the device), type of input data (speech chat, poem, programing), length of input per day (i.e. How much u actually need to type per day), how long it takes to learn it (e.g. voice vs steno vs other chorded keyboard design), etc. Multiple variables.

For each of these variable, we quantify it. Say 0 to 1. Then, we set satisfaction constraints. for example, the device's ergonomic score must be greater than 0.6, and the potential speed must be greater than 0.5, and learning time required must be less than 0.4, and availability or portability of the device must be greater than 0.6, etc. Then, we measure the scores of each device. Then we check which devices satisfies all inequalities. This is called Linear Programing. And the above is only about the question of: which is the best for typing. Similar can be said for which is best for gaming. There, you have variables like which game exactly, or which category of games, or what kinda mix of games, etc.

MTGAP layout

following is originally posted on 2017-07-17

apparently, some nerds are still designing keyboard letter layouts.

todo, read

it's like, is x++ faster or x=x+1? Like, keep hacking a dead horse.

it's by Michael Dickens

His layout is called MTGAP layout. Apparently based on evolutionary algorithm.

I haven't looked into detail what he's doing, but he seems to have spent significant effort, for like 10 years.

he's got a list of layouts, more than that i know. But lots of it is now dead link. See http://mdickens.me/typing/alternative_layouts.html

Just redone the navbar. So the navbar is on the left in the following pages Windows Keyboard Software Guide

Those pages are a bit old. Because i haven't been on Microsoft Windows much, but most importantly, i started to use programable keyboards, which is superior than OS key programing.
