Functor and monad examples in plain Java

이 글은 우리가 쓴 책, 'Reactive Programming with RxJava' 의 부록이었다. Reactive programming과 관련이 깊은 주제긴 하지만 모나드를 소개한다는 게 책과 썩 어울리지는 않았다. 그래서 나는 따로 블로그에 올리기로 했다. 프로그래밍을 다루는 블로그에서 *"반은 맞고 반은 틀릴 지 모르는 나만의 모나드 설명"*이란 것이 새로운 *"Hello World"*라는 점을 나도 잘 안다. 하지만 이 글은 펑터(functor)와 모나드(monad)를 자바 자료 구조와 라이브러리라는 각도에서 바라보고 있으며, 이는 공유할 정도의 가치는 있을거라 생각했다.

... my first disclosure. Man, it feels weird doing this.

update 6/6/16 I would like to stress something: I'm not saying "Don't buy an ASUS device" -- I see a lot of people who want to lambaste ASUS for this and boycott their hardware. This isn't what I want people to be doing by any stretch. Stupidly, I like the ASUS hardware I have (it's nice for the price) and I would rather see a pressure on ASUS as an OEM to stop shipping "value added software" to consumers; If you want to help Microsoft in pushing this mentality, go buy a signature machine from them. Microsoft provides support, but also only ships windows and a few select utilities that are essential to the functioning of the system (think: Radeon/Optimus and nVidia control panels) and fall heavily on the hardware makers (ATI, nVidia, Intel) to provide support for the harware.

Consider an ASUS device all you want. Start putting pressure on Microsoft that consumers want bloat-free devices and start voting with your money. Microsoft's store

깃 커밋 서명하는법

A. PGP key pair 등록

기존에 원래 사용하던 PGP key pair가 없을경우 새로 만들어야한다. 이미 key pair가 있을경우, 비밀키를 컴퓨터에 다운로드 해줘야한다.

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

	#!/usr/bin/env python

	import struct
	import sys

	class Instruction:
	def __init__(self, name, *args):
	self.name = name
	self.operands = args

	#include <stdio.h>
	#include <string.h>
	#include <taihen.h>
	#include <psp2kern/kernel/modulemgr.h>
	#include <psp2kern/kernel/threadmgr.h>
	#include <psp2kern/kernel/sysmem.h>
	#include <psp2kern/io/fcntl.h>

	#define DUMP_PATH "ux0:dump/"
	#define LOG_FILE DUMP_PATH "kplugin_log.txt"

	#!/bin/bash

	# Give the usual warning.
	clear;
	echo "[INFO] Automated Android root script started.\n\n[WARN] Exploit requires sdk module \"NDK\".\nFor more information, visit the installation guide @ https://goo.gl/E2nmLF\n[INFO] Press Ctrl+C to stop the script if you need to install the NDK module. Waiting 10 seconds...";
	sleep 10;
	clear;

	# Download and extract exploit files.
	echo "[INFO] Downloading exploit files from GitHub...";

	Bus 020 Device 002: ID 054c:09af

	bDeviceSubClass 0
	bDeviceProtocol 0

	#include <psp2/kernel/sysmem.h>

	int dynarec_test(void)
	{
	int block;
	int ret;
	void *base;
	int (*func)(void);

	// allocate block in VM domain

	<?php

	function browserhaxcfg_handle_urlparams()
	{
	global $ropchainparam, $ropchainselect, $arm11code_loadfromsd;
	$ropchainselect = 2;
	$arm11code_loadfromsd = 2; // download webkithax_tmp.bin over http

	//From here one can initialize $ropchainselect and $arm11code_loadfromsd by optionally checking the value of $ropchainparam which comes from URL param "rop".
