cantecim / Recursively copy a directory (using cp, tar or rsync).md

Recursively copy a directory (using cp, tar or rsync). Reformatted from http://snipplr.com/view/26670/

Recursively copy a directory (using cp, tar or rsync)

Original Source: http://snipplr.com/view/26670/

Reformatted for improved readability and personal reference.

How does one make a recursive, identical copy of /source/ into /target/?

I suppose you want to do that for archiving or duplicating something and want to preserve "everything". That includes permissions, ownership, filetypes, timestamps etc.

Secure random values (in Node.js)

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:

  • Don't use 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.
  • Don't use 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.
  • If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
  • If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Last active January 16, 2016 16:28 — forked from premiumFrye/pf-mobilePolyForm.js
A directive for making Android behave a bit more like iOS when filling out forms using the ionic framework. Directive will automatically advance cursor to next field when user taps return, and if the next field is a select input, automatically pop open options. Additionally, this directive solves an issue where angularjs won't update ng-model an…

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.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
