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.

Vanilla JavaScript Quick Reference / Cheatsheet

Just migrated it from Codepen.io to markdown. Credit goes to David Conner.

Working with DOM	Working with JS	Working With Functions
Accessing Dom Elements	Add/Remove Array Item	Add Default Arguments to Function
Grab Children/Parent Node(s)	Add/Remove Object Properties	Throttle/Debounce Functions

System Design Cheatsheet

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

Basic Steps

Clarify and agree on the scope of the system

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?

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. _Get out there and build things!

npm rank

This gist is updated daily via cron job and lists stats for npm packages:

Top 1,000 most depended-upon packages
Top 1,000 packages with largest number of dependencies
Top 1,000 packages with highest PageRank score

C99 List of Undefined Behavior

From N1256: (See http://port70.net/~nsz/c/c99/n1256.html#J.2)

A "shall" or "shall not" requirement that appears outside of a constraint is violated (clause 4).
A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2).
Token concatenation produces a character sequence matching the syntax of a universal character name (5.1.1.2).
A program in a hosted environment does not define a function named main using one of the specified forms (5.1.2.2.1).
A character not in the basic source character set is encountered in a source file, except in an identifier, a character constant, a string literal, a header name, a comment, or a preprocessing token that is never converted to a token (5.2.1).
An identifier, comment, string literal, character constant, or header name contains an invalid multibyte character or does not
