Basic metabolism mechanics

Water

Water - your metabolism needs it. Have a full hand-held bottle nearby at all times. Drink liberally - most estimates of recommended amount fall between 3-5 liters per day (a lot more than what you will usually drink).

Infact, forget all other drinks, especially soft drinks and artificial juices. Most of them are sugary and will become fat minutes after you drink them. Replace them all with water.

Where people struggle learning Django

Over the last 3 years or so I've helped a bunch of companies, small and large, switch to Django. As part of that, I've done a lot of teaching Django (and Python) to people new to the platform (and language). I'd estimate I've trained something around 200-250 people so far. These aren't people new to programming — indeed, almost all of them are were currently employed as software developers — but they were new to Python, or to Django, or to web development, or all three.

In doing so, I've observed some patterns about what works and what doesn't. Many (most) of the failings have been my own pedagogical failings, but as I've honed my coursework and my skill I'm seeing, time and again, certain ways that Django makes itself difficult to certain groups of users.

This document is my attempt at organizing some notes around what ways different groups struggle. It's not particularly actionable — I'm not making any arguments about what Django should or shouldn't do (at least

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Understanding `this` in JavaScript

It's easy to trip up on the meaning of this in JavaScript. The behavior is very different from other languages, which means we have to throw most preconceptions and intuition out the window.

The best way to think of this in JS is as a hidden function argument which is passed in a slightly awkward way. Instead of the normal passing of arguments:

fn(arg1, arg2, arg3)

	#include <sys/capability.h>
	#include <sys/types.h>
	#include <stdio.h>
	#include <stdlib.h>
	#include <unistd.h>

	#define nitems(x) (sizeof(x) / sizeof(x[0]))

	int
	main(void) {

	#include <OneWire.h>
	#include <LiquidCrystal.h>

	// For every sensor found it outputs to serial:
	// SensorID,CurrentTemp,Readout time,Current time
	// Info at: http://wiki.spodeli.org/Хаклаб/Температура

	OneWire ds(12); // on pin 12
	LiquidCrystal lcd(6, 7, 8, 9, 10, 11);

	LAN=eth0
	BRIDGE=virtbr

	print(paste(dates[i-1], dates[i]))
	tweets <- c(tweets, searchTwitter("#ISMB", since=dates[i-1], until=dates[i], n=1500))
