Clean Architecture
1. 一棟大廈不可能分成兩棟能完全獨立運作的大廈，但軟件通常由能獨立運作的小軟件所組成，所以有理由相信軟件工程比土木工程複雜 2. 軟件工程是內循環的，意思是用軟件A創造軟件B，之後又用軟件B改進軟件A，而土木工程是單向的，所以有理由相信軟件工程比土木工程複雜 3. 就算摩天大廈，起第一層和起第一百層的技術差不多，但軟件中不同層數的建築方法是完全不同，例如os層和web層，所以有理由相信軟件工程比土木工程複雜 4. 軟件工程中做同一件事的方法比土木工程多很多，所以有理由相信軟件工程比土木工程複雜
Convert 64 bits binary string to BigInteger and maintain the sign
The first and third method converted successfully with sign. The second one fail. The reason 3rd way working is : It convert to biginteger and convert to long (then we have sign),then convert back to biginteger (also with sign)

start point to build our own jtag for our risc-v cpu
After days of hacking, i finally found out there is a dummy driver in openocd. just ./configure –enable-dummy and run it by ./bin/openocd -c ‘interface dummy’ -c ‘adapter_khz 1’ , you can see the dummy driver is running and in the function “static int dummy_write(int tck, int tms, int tdi)”, we can manually toggle the…

Don’t use “skip” in antlr grammar for netbeans syntax highlight
use “channel (HIDDEN)” instead of “skip”, otherwise the netbeans will throw exception.
validate() in TableCellRenderer affect performance in windows
validate() in TableCellRenderer affect performance in windows, just read the source code of DefaultTableCellRenderer, just override it with empty function body will increase huge performance. Only windows affect this, mac and linux wont.
