ivandrofly / Unicode table
Created May 4, 2014 02:20
Unicode table - List of most common Unicode characters *
Unicode table - List of most common Unicode characters *
* This summary list contains about 2000 characters for most common ocidental/latin languages and most printable symbols but not chinese, japanese, arab, archaic and some unprintable.
Contains character codes in HEX (hexadecimal), decimal number, name/description and corresponding printable symbol.
What is Unicode?
Unicode is a standard created to define letters of all languages ​​and characters such as punctuation and technical symbols. Today, UNICODE (UTF-8) is the most used character set encoding (used by almost 70% of websites, in 2013). The second most used character set is ISO-8859-1 (about 20% of websites), but this old encoding format is being replaced by Unicode.
How to identify the Unicode number for a character?
Type or paste a character:

Set up a "standard" go project workspace with support for 3rdparty modules, version control repo and a template main package
# Install all the Go tools and godep tool
# Location of gobin is based on installation by OS X Homebrew
sudo -u admin GOPATH=/tmp GOBIN=/usr/local/opt/go/bin go get -u golang.org/x/tools/cmd/...
sudo -u admin GOPATH=/tmp GOBIN=/usr/local/opt/go/bin go get -u github.com/tools/godep

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

  1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }
#include <stdio.h>
#include <string.h>
#include <pulse/pulseaudio.h>
// Field list is here: http://0pointer.de/lennart/projects/pulseaudio/doxygen/structpa__sink__info.html
typedef struct pa_devicelist {
uint8_t initialized;
char name[512];
uint32_t index;
char description[256];

Introduction to "Fun" C (using GCC)
/**
* This are a collection of examples for C 201.
* These combine concepts you may or may not be
* familiar with and are especially useful for
* students new to C. There is a lot of really
* cool stuff you can do in C without any cool
* languages.
*
* This is file in particular is an introduction
* to fun function usage in C.

EDIT from 2019: Hi folks. I wrote this gist for myself and some friends, and it seems like it's gotten posted somewhere that's generated some (ahem, heated) discussion. The whitespace was correct when it was posted, and since then GitHub changed how it formats <pre> tags. Look at the raw text if you care about this. I'm sure someone could tell me how to fix it, but (thank you @anzdaddy for suggesting a formatting workaround) honestly this is a random throwaway gist from 2015, and someone more knowledgable about this comparison should just write a proper blog post about it. If you comment here I'll hopefully see it and stick a link to it up here. Cheers. @oconnor663

Here's the canonical TOML example from the TOML README, and a YAML version of the same.
