[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.

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.
