JSX, a year in

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

Bluebird .each vs .mapSeries vs .map
var Promise = require('bluebird');
var funcs = Promise.resolve([500, 100, 400, 200].map((n) => makeWait(n)));
funcs
.each(iterator) // logs: 500, 100, 400, 200
.then(console.log) // logs: [ [Function], [Function], [Function], [Function] ]
funcs
.mapSeries(iterator) // logs: 500, 100, 400, 200

Principles of Adult Behavior

  1. Be patient. No matter what.
  2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
  3. Never assume the motives of others are, to them, less noble than yours are to you.
  4. Expand your sense of the possible.
  5. Don’t trouble yourself with matters you truly cannot change.
  6. Expect no more of anyone than you can deliver yourself.
  7. Tolerate ambiguity.
  8. Laugh at yourself frequently.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Acronyms Seriously Suck - Elon Musk

From time to time, Musk will send out an e-mail to the entire company to enforce a new policy or let them know about something that's bothering him. One of the more famous e-mails arrived in May 2010 with the subject line: Acronyms Seriously Suck:

There is a creeping tendency to use made up acronyms at SpaceX. Excessive use of made up acronyms is a significant impediment to communication and keeping communication good as we grow is incredibly important. Individually, a few acronyms here and there may not seem so bad, but if a thousand people are making these up, over time the result will be a huge glossary that we have to issue to new employees. No one can actually remember all these acronyms and people don't want to seem dumb in a meeting, so they just sit there in ignorance. This is particularly tough on new employees.

That needs to stop immediately or I will take drastic action - I have given enough warning over the years. Unless an acronym is approved by me, it should not enter the SpaceX glossary.

Heroku scheduled restarts
#!/bin/sh
# Set up the Heroku scheduler to run this command every hour. See example setup at https://goo.gl/nMCSH3
#
# Requires env vars to be set in Heroku with `heroku config:set`:
# - HEROKU_APP_NAME: this is just the app name in Heroku, i.e. `heroku apps` will list all apps you have access to
# - HEROKU_CLI_USER: Once Heroku CLI is authenticated (https://goo.gl/Qypr4x), check `cat .netrc` (or `_netrc` on Windows),
# look for `login` under `machine api.heroku.com`
# - HEROKU_CLI_TOKEN: As above, but use the `password` field
