Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.

cd ~/node-latest-install

Better local require() paths for Node.js

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.

Possible solutions

simple squash without rebase
## within current branch, squashes all commits that are ahead of master down into one
## useful if you merged with upstream in the middle of your commits (rebase could get very ugly if this is the case)
## commit any working changes on branch "mybranchname", then...
git checkout master
git checkout -b mybranchname_temp
git merge --squash mybranchname
git commit -am "Message describing all squashed commits"
git branch -m mybranchname mybranchname_unsquashed
git branch -m mybranchname

New ES6 constructor features and semantics: Alternative 2 manual super in derived classes

New ES6 Constructor Semantics and Usage Examples

Manual super: Alternative Design where subclass constructors do not automatically call superclass constructors

This Gist presents a new design of class-based object construction in ES6 that does not require use of the two-phase @@create protocol.

One of the characteristics of this proposal is that subclass constructors must explicitly super invoke their superclass's constructor if they wish to use the base class' object allocation and initialization logic.

An alternative version of this design automatically invokes the base constructor in most situations.

1. encode multiple bitrates with keyframe alignment:
ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4
My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.
