Ma proposition pour un `mek` bien, dites-moi vos opinions sur l'interface. Celle-ci passe autant que possible par le système de fichiers, parce qu'un `mek` bien sait parler aux files.
|
||||
|
||||
Problems solved:
|
||||
* Forgotten dependencies: build in isolated environment
|
||||
* Reactive builds (auto-rebuild): mek watch

* Wikipedia's illustration of a [NAND gate's physical layout](https://en.wikipedia.org/wiki/CMOS#Example:_NAND_gate_in_physical_layout) clearly shows how NMOS and PMOS transistors are created on a silicon substrate, as well as a schematic representation of the resulting layers. Page visited on 2019-03-12.
|
||||
* Some people have built small integrated circuits (e.g. inverters) at home, using simple equipment: [Jeri Ellsworth](https://hackaday.com/2010/03/10/jeri-makes-integrated-circuits/), [HomeCMOS](https://hackaday.com/2012/07/09/make-your-own-integrated-circuits-at-home/).
|
||||
* [visual6502.org](http://visual6502.org/), a sumulation of the 6502 CPU based on photos of the silicon die. It features an online zoomable view of the CPU with different colors for the logic states, in which wires and transistors blink as the CPU executes instructions.

## Screen
|
||||
|
||||
* [OLPC display](http://wiki.laptop.org/go/Display#Understanding_the_display_system)
|
||||
|
||||
The OLPC (One Laptop Per Child project) integrates a Pixel Qi
|
||||
screen. This screen uses subpixels (red, green, blue) with a square
|
||||
aspect ratio using a non-traditional layout of the subpixels. It
|
||||
features a reflective higher-resolution black and white display,
|
||||
which works in bright sunlight. Behind that black and white layer,
|
||||
there is a backlit screen with colored pixels. This means that
|
||||
depending on the lighting of the environment and backlight
|
||||
brightness, the color may fade away, but a crisp black and white
|
||||
picture will always be visible. This also allows for reduced power
|
||||
consumption if the backlight is disabled or its brightness reduced.

# Bootstrap
|
||||
|
||||
Bootstrapping is an important facet of technology. By having a clear
|
||||
path to bootstrap a given branch of science or technology we can
|
||||
explain it in a more synthetic way, implement things in a clean way
|
||||
while getting rid of historical blunders and baseless
|
||||
traditions.
|
||||
|
||||
Having some hindsight on the shortest path to success can give some
|
||||
foresight on the future directions to explore. If the failed paths are
|
||||
also made clear, this foresight might extend to knowing which future
|
||||
directions should likely be avoided.

|
||||
|
||||
RepRap is a 3D printer that is capable of replicating most of its
|
||||
parts which are not off-the-shelf.
|
||||
|
||||
RepStrap projects are about creating an initial RepRap without an
|
||||
existing RepRap and without advanced tooling.

|
||||
|
||||
The GVCS aims to design construction kits for 50 industrial machines
|
||||
which would be necessary for a self-sufficient village. Among these
|
||||
are the compressed earth brick press (used to make bricks for
|
||||
buildings), a tractor, a wind turbine, or the Fabrication
|
||||
Construction Set which can be used to build the other machines.

Tests for the web pages.

* Checks that the pages are valid Polyglot Markup (an HTML5 / XHTML chameleon, TODO link to references)
|
||||
* Uses the W3C validator to check that the pages are valid HTML 5, XHTML 1.0, XHTML 1.1, as well as valid HTML 3.2, HTML 4.0 with the exception of the obvious incompatibilities (doctype and self-closing tags)
|
||||
* Checks that there are no broken links between the pages, and no broken links to external pages.
