Gist — Manage in one repository many gists by using git submodule

Gist is a nice service. We can write code so easily and manage files as repository.

But bad points are …

• Many repository
• Gist destributes random hash to perticular gists (repositories).
• So difficult to find or remember contents as repository.

CI & CD:
========
2 core software development processes
CI process of automating regular code commits followed by an automated build and test process designed to highlight intergration issues early.
Additional tooling and functionality provided by Bamboo, CruiseControl, Jenkins, Go and TeamCity etc.
workflow based
CD takes the form of a workflow based process which accepts a tested software build payload from a CI server. Automates the deployment into a working QA, Pre-prod or Prod environment.
AWS CodeDeploy and CodePipeline provide CI/CD services
Elasticbeanstalk and CFN provide functionality which can be utilized by CI/CD servers.

React debouncing pattern for API calls

Classic debounce function:

const debounce = (fn, delay) => {
      let timer = null;
      return function (...args) {
          const context = this;
          timer && clearTimeout(timer);

timer = setTimeout(() => {

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
