two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)
// Ported from Stefan Gustavson's java implementation

Tips for Writing Portable Node.js Code

Node.js core does its best to treat every platform equally. Even if most Node developers use OS X day to day, some use Windows, and most everyone deploys to Linux or Solaris. So it's important to keep your code portable between platforms, whether you're writing a library or an application.

Predictably, most cross-platform issues come from Windows. Things just work differently there! But if you're careful, and follow some simple best practices, your code can run just as well on Windows systems.

Paths and URLs

On Windows, paths are constructed with backslashes instead of forward slashes. So if you do your directory manipulation

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

IamAdiSri / Python3, Pip3, Virtualenv and Virtualenvwrapper Setup
Last active May 9, 2022 22:08 — forked from evansneath/Python3 Virtualenv Setup
Setting up and using Python3, Pip3, Virtualenv (for Python3) and Virtualenvwrapper (for Python3)
First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py
$ cd <download location>
$ sudo -H python ./get-pip.py
Installing pip also installs Python3
To run Python3
$ python3
Install pip3 by just executing the same file as in the step above, but this time using Python3
$ sudo -H python3 ./get-pip.py

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
