I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

To remove a submodule you need to:

module.exports = function CustomError(message, extra) { | |
Error.captureStackTrace(this, this.constructor); | |
this.name = this.constructor.name; | |
this.message = message; | |
this.extra = extra; | |
}; | |
require('util').inherits(module.exports, Error); |

cloud-init
is absolute cancer. Its code is horrible. It has no documentation at all.
It took me 5 fucking hours to figure out how to properly configure networking on recent
cloud-init
(Ubuntu 16.04 cloud image
) with local datasource.
It's not mentioned anywhere you need to provide dsmode: local
. (but only if you need network-config,
besides that everything is fine; someone below noted that -m
flag does the same thing, good to know) Of course nobody needs documentation for network-config
format
either. (cloudinit/net/__init__.py
is a protip, enjoy the feces dive)
Oh, and by the way - no, it's not possible to provide network-config
to uvt-kvm
without patching shit.

Not all random values are created equal - for security-related code, you need a specific kind of random value.
A summary of this article, if you don't want to read the entire thing:
Math.random()
. There are extremely few cases where Math.random()
is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.crypto.getRandomBytes
directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.uuid
, specifically the uuid.v4()
method. Avoid node-uuid
- it's not the same package, and doesn't produce reliably secure random values.random-number-csprng
