# This is because, although xubuntu 18.04 has reverse scrolling option in touchpad

JS hoisting by example

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)

View global-gitignore.md

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.

Mac

git config --global core.excludesfile ~/.gitignore

Windows

git config --global core.excludesfile %USERPROFILE%\.gitignore

View gist:22f0cdca75190b9a473f

How to unbrick an Amazon Kindle Paperwhite™

This guide instructs you in how to unbrick an Amazon Kindle Paperwhite. The consequences of following it are your own responsibility. This method (opening the Kindle and using the serial interface) should be a last resort and should only be considered if other methods fail

The Guide

  1. Pry open Kindle using a prying tool
  2. Unscrew the screen and remove it from the base. Note that there's a screw hidden under the adhesive at the top in the middle
  3. Solder tin wire to serial ports on the bottom
  4. Attach tin wire to USB TTY device (order is ground, RX, TX, from the kindle's perspective, where GND is the smallest pad) and plug USB TTY device into your computer
  5. Open Putty on your computer in serial mode, with the serial port specified as your USB device and baud configured to 115200

Code Review
View gist:5934429

###Code Review

É uma técnica onde o desenvolvedor tem seu código revisado por outro desenvolvedor antes de commitar o código.

O commitador deve explicar cada arquivo que está sendo commitado, tanto do ponto de vista técnico quanto de negócio.

Cada trecho de código apontado como alteração pelo "diff" deve ser devidamente explicado ao revisor.

É papel do revisor questionar sobre o código, sugerir melhorias e exigir detalhes sobre a regra de negócio.
