You can't use RAC() directly on a UIButton because of the UIKit design:

RAC(self.button.titleLabel, text) = titleSignal;  // Don't do this.

One of the solutions is using dynamic property to support RAC() binding macro:

// .h

// Just copy the fllowing code into a .m file, and include the XAspect to you project. 
// Then you'll see console log messages when objects of specific classes were deallocated.
// The block `AspectPatch(-, void, dealloc)` will be invoked just before `-dealloc` aka 'before advise'.


// Using XAspect
#import <XAspect/XAspect.h>
// Headers for classes you want to track
#import <CMDPUserLogin/UAMLoginViewController.h>
#import <CMDPUserLogin/UAMLoginTableViewController.h>

如何學習 Meteor.js (第一階段)

Meteor 是一個 full-stack 的開發框架 (或者該說是平台)，它可以利用一種語言 (JavaScript) 來輕鬆完成前後端的開發。是目前前景看好的選擇。

本階段的目標是：

• 了解 Meteor 是什麼樣的平台，基本架構，可以做到什麼樣的事情 (2.5 hr)
• 能夠自己獨立完成一個 Meteor 的 ToDo App (不斷的練習一樣的 App，直到完全熟悉，+10 hr)

這階段大約花 10-20 hr，可以利用一個週末的兩天時間，或是一個禮拜的晚上來完成。

A better async/reactive function design in JS (or any other languages) — the Universal Currying Callback (UCC) Design

For the principle "Don't call us, we'll call you", the modern function design uses callbacks, Promise, or monad/stream-based techniques (e.g. Rx) to let you subscribe the async results.

The following is a usual JS function implementation using the callback for async:

function register(username, password, email, callback) {
 // processing async work

VSCode 想等個寬，太難了 (借用標題)

緣由 (是個古老的坑):

• VSCode 的等寬字，在中英文會有排版不對齊的問題。這在寫 markdown Table 時，會有嚴重跑版的問題。
• 問題是來自於 VSCode 是用 Electron 開發，也就是介面顯示是由 Chromium 渲染導致 (Chromium 對中文等寬字渲染不對齊的 bug)。
• 目前沒看到有人修正這個根本性問題；目前的 workaround，就是改用能夠使中英文保持 2:1 等寬的字型。

來找個可用字型 (繼續排坑):
