STRML / ResizeSensor.js
Created Apr 21, 2018
A resize sensor component for React that doesn't use iframes, objects, or require ResizeObservers.
View ResizeSensor.js
// @flow
import * as React from 'react';
type Dimensions = {width: number, height: number, ref: ?HTMLElement};
type Props = {
children?: React.Node,
className?: string,
onResize: (dimensions: Dimensions) => any,
};

// For a while, webpack has had issues with [chunkhash] being unstable and not reflecting the actual

Relying on React as an external
View gist:2117f574726bdf0b8d58

The problem:

When writing a React component, you want to target all environments. It is easy to generate a build that will work on the server and browser with Webpack, and as a bonus you can use loaders (like babel-loader for ES6 code).

When you generate this bundle, you should rely on "react" as an external so it isn't included in the bundle. In all environments this is desired behavior so you don't duplicate "react" and break it. This is necessary both because it would make a much larger bundle than necessary, but also because React behaves badly when multiple copies are loaded.

If you do this, you'll end up with a UMD shim like:

(function webpackUniversalModuleDefinition(root, factory) {

STRML / overrideSlack.lua
Created Jul 10, 2015
Lua snippet for Hammerspoon to bind ctrl-tab and ctrl-shift-tab back to switching channels.
View overrideSlack.lua
--
-- Fix Slack's channel switching.
-- This rebinds ctrl-tab and ctrl-shift-tab back to switching channels,
-- which is what they did before the Teams update.
--
-- Slack only provides alt+up/down for switching channels, (and the cmd-t switcher,
-- which is buggy) and have 3 (!) shortcuts for switching teams, most of which are
-- the usual tab switching shortcuts in every other app.
--
local ctrlTab = hotkey.new({"ctrl"}, "tab", function()

STRML / fixperms.sh
Created Jun 30, 2012
A few useful files for running a nodejs server. I keep update-project.js in /root so when I ssh in I can just run it. my-project.conf runs the project as the user 'www-data', and so fixperms.sh makes sure the project folder is readable/writable.
View fixperms.sh
#!/bin/sh
T=/usr/local/mycompany/my-project
chown -R www-data:root $T
find $T -type d ! -perm 770 -print -exec chmod 770 {} \;
find $T -type f ! -perm 660 ! -name "*.sh" -print -exec chmod 660 {} \;
