jose8a / Nokogiri---BrewUpdate Error Fix

Last active August 29, 2015 14:15

Error: Permission denied - /usr/local/Cellar/libiconv/1.14 when running brew upgrade. ==> possible solution

	Original issue thread here: https://github.com/sparklemotion/nokogiri/issues/754

	I know it's a long time after this issue was closed and I appreciate this is a libiconv / homebrew issue, but just in case others come this way just like me...

	In the process of trying to get a zero warnings install of nokogiri on Mac OSX 10.9.3... I had the same problem as @geraldarthur upgrading from libiconv 1.13 to 1.14, namely:
	Error: Permission denied - /usr/local/Cellar/libiconv/1.14 when running brew upgrade.
	My kludge -
	ls -l /usr/local/Cellar/ showed all directories except libiconv owned by me. libiconv owned by root and not otherwise writable. So permission denied not surprising.

	$ ls -l /usr/local/Cellar/

Last active August 29, 2015 14:16

Iterating/recursing over files in a directory. 'Find' is more powerful and flexible.

	#!/bin/bash

	# Method #1: Recursive 'find' w/it's powerful -OPTIONS filtering
	# and then piping the results to a 'while' command for performing
	# multiple file-by-file actions.
	#
	# Only explore this folder level
	# Only return "dotfiles"
	find . -maxdepth 1 -name ".*" \| while read fname; do
	regex="^\./(\.[a-zA-Z0-9_]+)"

My Cheatsheet for commands I've found very useful, but not used often enough to commit usage to memory.


	# Symbolic (soft)-linking files
	# Example: ln -s ./myfile $HOME/myfile creates a symlink in the $HOME folder that
	# points to myfile in the current directory.
	# Format:
	ln -s path/to/realfile path/to/symlink

Brief notes on Meteor for CS 294-101. Many of the key architectural ideas in Meteor are described at https://www.meteor.com/projects.

BSD as example of great system design. Application primitives: processes run by a scheduler, sockets, sys calls, virtual memory, mbufs. What makes something a platform. Unix vs Multics.
History of application architectures. Mainframes (e.g. IBM 360 / 3270), client-server (e.g. Win32), web (e.g. LAMP), cloud-client. Oscillation of where the software runs. Thin vs thick clients, data vs presentation on the wire. Changes driven by massive forces (cheap CPUs, ubiquitous internet, mobile). New architecture for each era.
What it takes to make modern UI/UX. Mobile. Live updating. Collaboration. No refresh button. All drive the need for “realtime” or “reactive” system. Very different from HTTP era.
Four questions: 1 — how do we move data around; 2 — where does it come from; 3 — where do we put it; 4 — how do we use it?
