| ;; React supports "refs" as a way for a component to get a | |
| ;; handle to its children. Classically, refs were string-based. | |
| ;; Recent versions of React support callback attributes as a | |
| ;; more elegant variant of accessing DOM notes or components. | |
| ;; | |
| ;; This example uses a Form-3 component as per | |
| ;; https://github.com/Day8/re-frame/wiki/Creating-Reagent-Components | |

| ;; For callback refs, see React's documentation | |

| Usage... | |
| Vcxsrv [:<display>] [option] | |
| :display-number | |
| Vcxsrv runs as the given display-number, which defaults to 0. | |
| To run multiple instances, use unique display-numbers. | |
| -a # default pointer acceleration (factor) | |
| -ac disable access control restrictions | |
| -audit int set audit trail level |
Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...
// see: https://github.com/chadoe/docker-cleanup-volumes
$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker volume ls -qf dangling=true | xargs -r docker volume rm
| var rngstate; | |
| function MathRandom() { | |
| // Our own implementation of Math.random(). | |
| // Source code was copied from https://github.com/v8/v8/blob/4.6.85/src/math.js#L131 | |
| // You need to initialize rngstate with `solve` before this can be used. | |
| // If using node.js, you have to s/18030/18273/g here and in `solve` since they implement it slightly differently: https://github.com/nodejs/node-v0.x-archive/blob/d13d7f74d794340ac5e126cfb4ce507fe0f803d5/deps/v8/src/math.js#L146 | |
| console.assert(rngstate, "You need to set the global variable `rngstate` first. For example: `rngstate = solve(Math.random(), Math.random());`"); | |
| if (!rngstate) return; | |
| var r0 = (Math.imul(18030, rngstate[0] & 0xFFFF) + (rngstate[0] >>> 16)) | 0; | |
| rngstate[0] = r0; |
These are for the combined vim-sexp (https://github.com/guns/vim-sexp) and vim-sexp-mappings-for-regular-people (https://github.com/tpope/vim-sexp-mappings-for-regular-people) plugins. vim-sexp is neat on its own but Tim Pope makes common stuff much easier.
Note that some vim-sexp functionality depends on <LocalLeader> mappings. This is a different leader key than the global leader, and is the variable maplocalleader (instead of mapleader). To see if you have this set, use :echo maplocalleader; if it errors out you'll need to set it, otherwise it will echo the key. If you want to set your LocalLeader to <Space>, you'll need two commands in your .vimrc, since by default <Space> is bound to <Right> in normal mode:
nnoremap <Space> <Nop>
let maplocalleader=" "

2015-01-29 Unofficial Relay FAQ
Compilation of questions and answers about Relay from React.js Conf.
Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.
Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
