[Weismile生活] 2017/2018整理比較海外刷卡手續費費用與海外刷卡現金回饋信用卡優勢
當回饋大於>手續費!!就推薦申辦,不過如果沒也常出國,其實也可精算一下是否需要!如果常出國就一定是推薦要辦一張!以weiwei自己來說,假設每次出國都花10萬台幣(一年下來至少手續費就要1萬台幣了!(一萬台幣至少也有個日本來回近兩趟了))而且這個時候如果有一張信用卡可以有海外現金回饋的信用卡那就太重要了因為扣掉手續費之外還可以刷卡賺現金,超划算!

[世界公民文化中心] 想讀懂新聞英文,先看懂「新聞時態」
許多人在練習新聞英文時,新聞的標題讀起來時常似懂非懂,部分字彙為了精簡內容會省略冠詞、be動詞,與一般英文的習慣不盡相同,最大的特色就在時態,因為新聞想要表現時間的臨場感、時間感,用了大量的現在式,為的就是不讓讀者覺得是過去的事件,所以有一種好像新聞標題都看不見過去式的錯覺,這裡列出幾項新聞英文常用的時態與意思。

[DataStax] A deep look at the CQL WHERE clause
While they share similar syntaxes, there are lots of differences between CQL and SQL. The reasons for these differences come mainly from the fact that Cassandra is dealing with distributed data and aims to prevent inefficient queries. One of the places where CQL differs a lot from SQL is the WHERE clause. The goal of this post is to describe what is supported by the CQL WHERE clause and the reasons why it differs from normal SQL.

DKIM  寄件網域驗證技術簡介
由於SMTP規範的瑕疵(或者為了方便),寄件人的 Mail Address 和實際寄信的 Mail Server 是可以不一樣的。 ... DKIM的目的就是用來防止垃圾郵件製造者偽造您網域的寄件者來傳送郵件。 DKIM 使用簽章的方式,在外寄郵件的郵件標頭加上一個數位簽章,收件者只要檢查郵件中是否包含這個網域簽名,即可確認該郵件的寄件者地址確實屬於您網域中的地址,而且未在寄件途中遭到竄改。

[2017DoneRight] Sending emails with SMTP and Amazon SES in Ruby on Rails
In the past I have used services such as SendGrid and Mandrill. But since they switched Mandrill to an add-on for MailChimp premium users, Amazon SES in my opinion is the first choice for small to medium web applications. Cost of sending 40,000 emails per month with Amazon SES is mere $4 which is way cheaper than the other competitors.

[Technology Conversations] Java Build Tools: Ant vs Maven vs Gradle
Gradle combines good parts of both tools and builds on top of them with DSL and other improvements. It has Ant’s power and flexibility with Maven’s life-cycle and ease of use. The end result is a tool that was released in 2012 and gained a lot of attention in a short period of time. For example, Google adopted Gradle as the default build tool for the Android OS.

[AgoraPulse] How Does Digital Marketing Differ From B2B to B2C?
B2B marketers have to create stellar content that takes time consuming research and impeccable presentation skills to reach a small pool of clients who may or may not hire them. Conversely, B2C companies have the overwhelming task of standing out in the crowd, reselling their product over and over to create customer loyalty, and appealing to an array of distinct personalities within one audience.

[Brave New Geek] Building a Distributed Log from Scratch, Part 1: Storage Mechanics
Essentially, it’s a timestamp and an event, a when and a what, and typically appended to the end of a file. But when we generalize that pattern, we end up with something much more useful for a broad range of problems.

[Gamasutra] The sunk cost fallacy: Devs describe how it almost destroyed them
It's human nature to get attached to our work. ... you must learn to cut the overambitious, the unworkable, the self-indulgent. If you don't...well, as we're about to see, it can drag a project down and maybe even stretch the company's finances to breaking point — especially if keeping something you recognize is bad means putting in significant additional work.

[Miula 觀點] 成長駭客必備的MVP(最小可行產品)概念,到底哪個版本才比較正確?
其實 MVP 的概念,不在於最終的產品,而是在於一個商業觀念的市場驗證,做出第一個版本的產品來測試 PMF (Product-Market-Fit)。也就是說,其實最終產品是什麼,在一開始的時候根本不知道,或者是只有一個模糊的概念,但卻是隨時可以被替換更改的。為什麼要做最小可行產品 MVP 呢? 就是為了避免一開始就把整個產品都定義完成,但最後做出來的東西根本是市場不要的,而浪費了時間、金錢與精神。MVP 這個概念的真正精神,在於在市場測試後的修正彈性。

[Words and Code] Safer SQL: Using ActiveRecord Transactions
There’s one golden rule of the transaction block: it will only rollback the transaction if an error is raised. Why is this important? Well, calling something like save or destroy inside of a transaction will not raise an error; if something goes wrong, these methods will simply return false. Which means that our transaction block will continue, since there was no error raised!

How to Read Mathematics
Mathematics has a reading protocol all its own, and just as we learn to read literature, we should learn to read mathematics.  Students need to learn how to read mathematics, in the same way they learn how to read a novel or a poem, listen to music, or view a painting.  Ed Rothstein’s book, Emblems of Mind, a fascinating book emphasizing the relationship between mathematics and music, touches implicitly on the reading protocols for mathematics.

[星空博客] CAP原理、一致性模型、BASE理论和ACID特性
CAP原理指的是,CAP的三个要素最多只能同时实现两点,不可能三者兼顾。因此在进行分布式架构设计时,必须做出取舍。而对于分布式数据系统,分区容忍性是基本要求,否则就失去了价值。因此设计分布式数据系统,就是在一致性和可用性之间取一个平衡。对于大多数web应用,其实并不需要强一致性,因此牺牲一致性而换取高可用性,是目前多数分布式数据库产品的方向。当然,并不是完全不管数据的一致性。牺牲一致性,只是不再要求关系型数据库中的强一致性,而是只要系统能达到最终一致性即可,考虑到客户体验,这个最终一致的时间窗口,要尽可能的对用户透明,也就是需要保障“用户感知到的一致性”。

Introducing Functions as a Service (FaaS)
Functions as a Service or (OpenFaaS) is a framework for building Serverless functions on top of containers. I began the project as a proof of concept in October last year when I wanted to understand if I could run Alexa skills or Lambda functions on Docker Swarm. After some initial success I released the first version of the code in Golang on GitHub in the December.
