Turning Off Github Issues

My friend Michael Jackson turned off github issues on one of his smaller projects. It got me thinking...

Maintainers getting burned out is a problem. Not just for the users of a project but the mental health of the maintainer. It's a big deal for both parties. Consumers want great tools, maintainers want to create them, but maintainers don't want to be L1 tech support, that's why they

How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: [email protected]:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Caveat

You're not going to get a beautiful EPUB out the other end - if that's what you're looking for, expect to do some manual clean-up work yourself.

Basic order of operations:

• Convert your PDF to an OCR-friendly format
• OCR that shit into plaintext
• Convert that plaintext into your format of choice (in this case, an EPUB)

Developer Production

• Measure success of developer experience by time to setup.
• Same scripts for CI as for developer sandbox.
• Each app should include the build sripts that are used to compile from scratch in a sandbox.
• Mentality - Ask the question - Can we opensource/handoff this repo as it stands today?
• Readme.md must be complete and contain 3 main sections

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
