I thought Java swing is pixel graphic
In last 20 years, I thought Java swing is pixel graphic, but i found out it is vector. I tried to draw a 1 pixel line with 45 degrees, and when i zoom out, i proved it is not pixel base. So all drawLine, drawRect function calls are vector graphic. 2019/07/30

x86 disassembler預研成功
x86 disassemble預研成功，感謝Rod Pemberton朋友在alt.lang.asm上面的幫忙，原來Intel instruction雖然係CISC但可以在未decode所有Byte之前把Instruction切割出來。還有，切割比我想像人來得簡單。我現在的問題就是，RISC的所謂固定長度指令好像不是傳說中所說的巨大優勢。 2019/07/10
