multicore in java/javascript/python

Java thread can be a native thread.

JavaScript is single thread.

Although Python thread is a native thread, but due to GIL, CPython can not leverage multicore hardware.

[Android] ndk stl build

終於知道如何用ndk-build stl
doc中說可以在Android.mk[x]中設定變數, 不過不成功.

--> 原來是看錯檔名 應該是Application.mk才對
--> 加一個Application.mk就可以build

[x] 後來下在command中:
[x] ndk-build APP_STL=stlport_static

其中 APP_STL 可以有幾個選擇
system -> Use the default minimal C++ runtime library.
stlport_static -> Use STLport built as a static library.
stlport_shared -> Use STLport built as a shared library.
gnustl_static -> Use GNU libstdc++ as a static library.

gnu多了exception.

發現一個不錯的功能可以remote debug android process
連 system_server 也可以debug.

最右邊的欄位就是remote debug的 port number
切到 Debug 頁面, 選 "Debug Configuration..."
新增一個 "Remote Java Application" 選項
選擇你的project & 填上 port number 就可以用了

Android中的LIKELY和UNLIKELY

這篇解釋的不錯

if(LIKELY(exp)) 就是告訴compiler這個if branch較常執行, 可以針對他作優化
if(UNLIKELY(exp)) 相反則是以else branch為優化的對象.
