JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

Introduction

If you are familiar with Java's generics, and are coming to Rust, you might be lead to assume that its generics are working the same way.

However, due to the different type systems, and different implementation details, there are quite a few differences between generic code in both languages.

This document tries to give a short summary about those differences:

#Error management in gulp

Sucking at something is the first step to becoming sorta good at something

No one can assure you, that plugins will run smooth in any circumstances (except for tests - they could), so neither should you convince anyone, that your plugin will never break. Only thing, that you could possibly do (if something gone wrong) - is gracefully inform your plugin user, that something went wrong and die.

We are will use this plugin from beginning to demonstrate error management. Suppose you have a task in gulpfile.js that contains this code (we modified it a little bit to be closer to real-usage):

var coffee = require('gulp-coffee');

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Difference between Debounce and Throttle

Debounce

Debounce a function when you want it to execute only once after a defined interval of time. If the event occurs multiple times within the interval, the interval is reset each time.
Example A user is typing into an input field and you want to execute a function, such as a call to the server, only when the user stops typing for a certain interval, such as 500ms.

Throttle

How to Win Friends and Influence People

Fundamental Techniques in Handling People

Don't criticize, condemn, or complain.
Give honest and sincere appreciation.
Arouse in the other person an eager want.
Never show others that you are not interested in what they have to say.
