Understanding Clojure transducers through types
-- http://conscientiousprogrammer.com/blog/2014/08/07/understanding-cloure-transducers-through-types/
-- Transducer의 자료형을 만들기 위해서는 Rank-2 type이 필요하다.
{-# LANGUAGE RankNTypes #-}
-- 함수형 프로그래밍에서 함수는 1급 시민이다. 함수를 조합하고 변환하는 것은 매우 평범한 것이다.
-- h = (f . g)라면 f (g x) = h x 이다.
-- reducer는 reduce에서 사용되는 함수에서 다양한 how를 제거하고 일반화하여 정의한 것이다.
-- 그리고 transducer는 reduce를 새로운 reducer로 변환시키는 함수이다.
-- haskell의 type system은 새로운 것에 대한 명확한 이해에 도움을 준다.

Python script to efficiently concatenate S3 files
'''
This script performs efficient concatenation of files stored in S3. Given a
folder, output location, and optional suffix, all files with the given suffix
will be concatenated into one file stored in the output location.
Concatenation is performed within S3 when possible, falling back to local
operations when necessary.
Run `python combineS3Files.py -h` for more info.

Tmux is a "terminal multiplexer", it enables a number of terminals to be accessed and controlled from a single terminal.
If you use Debian/Ubuntu, you can just run apt-get install tmux, and voila.
Since the title was about centos 7, then do the following step to install tmux.
(1). tmux has a library dependency on libevent which, of course, isn’t installed by default.
$ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
$ tar xzvf libevent-2.0.21-stable.tar.gz
$ cd libevent-2.0.21-stable
$ ./configure && make

From Require.js to Webpack - Part 2 (the how)

This is the follow up to a post I wrote recently called From Require.js to Webpack - Party 1 (the why) which was published in my personal blog.

In that post I talked about 3 main reasons for moving from require.js to webpack:

  1. Common JS support
  2. NPM support
  3. a healthy loader/plugin ecosystem.

Here I'll instead talk about some of the technical challenges that we faced during the migration. Despite the clear benefits in developer experience (DX) the setup was fairly difficult and I'd like to cover some of the challanges we faced to make the transition a bit easier.
