Google Tag Manager(GTM) is a back office for quickly managing HTML on webpages, basically, it enables the maintainer to do Everything on their website without changing the code base. There are three major elements in GTM which are Tag, Variable, and Trigger.

Tag

A Tag will be triggered by the Trigger you set and passing both the system defined variables and the user-defined variables to your Tag, then you could take the action such as sending it to GA or manipulate DOM on your pages.

Variable

Other than System defined variables, you could create your own by Javascript:
Select User-Defined Variables, then select the type Custom Javascript

學徒模式一書的架構是以一篇篇的主題連接起完整的學徒Roadmap，每篇中以情境 問題 解決方案 行動來引領學徒如我邁向軟體工藝之路，本次再讀此書深覺應身體力行，決定把一些書中提及的的行動實行於部落格內

正視你的無知

明天我將顯得更加愚昧，並習慣他。

大意

本篇訴說儘管已經熟悉某些技能並讓他人倚重，但總是會遇到自身所缺的知識，此時勇於放下自尊顯露無知，說不知道，問身邊的專家為什麼才是最快的學習途徑，特別是當你問問題的對象認為你知道問題的答案！

行動 - 列出五件工作中你不理解的事放在大家看的到的地方並持續更新這份清單

1. WebAssembly
2. Web Worker
3. How Vue core works?
4. How to write a Compiler?
5. How to build a LIFF Application?

Recommend plugins

• Make your diff so fancy - diff-so-fancy
• ZSH Git alias

Determine progressive JPEG by it’s content

From wiki-JPEG, we could see a baseline/progressive JPEG have byte marker mapping differently as following:

So to tell the image is progressive JPEG, we need to check if it contains 0xFF, 0xC0 which is c2ff in Two-byte hexadecimal display.
