前言

最近開始run startup,非常忙碌,沒什麼時間寫blog,但是有些難找的東西,還是要記錄一下,看看能不能幫到別人。

[ScaVa->Scala] Introduction to Scala Development

前言

這件文件是在公司內部向一些新踏入Scala領域的同事們介紹所使用的資料,因此適合有程式開發經驗,並且想Scala領域中的朋友們。 底下列了一些學習Scala的資源、並列出一些我們自己開發常用到的Libraries並適合新手來學習使用的。

Category theory(範疇論)之什麼是Functor, Applicative, Monad, Semigroup, Monoid?

之前曾經寫過一篇 什麼是Monad? ,裡面提到了對於Monad的解釋,而今天進一步解釋這些在Functional Programming中常見到的詞:Functor, Applicative, Monad, Semigroup, Monoid。 透過放在一起比較,讓我們更清楚這些之間的差別與關係。

##Functor

在提到Functor之前,請先了解一下scala中map的作用,map可以讓你傳入一個function,而透過這個function是可以從F[A]轉換成F[B],這裡的F不管他(就是代表外面的包裝不會變),而裡面的A型態轉成B型態。

例如:

Automatically backup a MongoDB database to S3 using mongodump, tar, and awscli (Ubuntu 14.04 LTS)
View mongodb-s3-backup.sh
#!/bin/sh
# Make sure to:
# 1) Name this file `backup.sh` and place it in /home/ubuntu
# 2) Run sudo apt-get install awscli to install the AWSCLI
# 3) Run aws configure (enter s3-authorized IAM user and specify region)
# 4) Fill in DB host + name
# 5) Create S3 bucket for the backups and fill it in below (set a lifecycle rule to expire files older than X days in the bucket)
# 6) Run chmod +x backup.sh
# 7) Test it out via ./backup.sh
