Dagger

Dagger 1 issues, which has been addressed in Dagger 2

• Graph composition at runtime — hurts performance, especially in a per-request use case (backend scenario)
• Reflection (i.e. Class.forName() on generated types) — makes generated code hard to follow and ProGuard a nightmare to configure
• Ugly generated code — especially, in comparison to similarly written manual instantiation from factories

Java

• Java 8
• Java 9

C++

C++11

• Lambda

for_each(s, s+sizeof(s), [&Uppercase] (char c) {
  if (isupper(c))
  Uppercase++;
});

• Type deduction (auto)

• Uniform init syntax: brace notation

int* a = new int[3]{1, 2, 3}; // C++11 and up

class X {
  int a[4];
public:
  X() : a{1,2,3,4} {} //C++11, member array initializer
};

• Delete the default functions.

  nullptr type should be used instead of NULL constant.

• Standard library:

  • thread.
  • auto_ptr
  • some new algorithm functions and data structure.

C++15

Chat system

• fb chat head.

Misc

• AI bot

Issue

• Bot command not work on the web.
• User and chat log had been deleted on Phone, but still shown on the Web (Firefox).
• Firefox web login input show red border eventhough I didn't enter anything.
• Console log should be disable in production.
