失败者应该缄默,像种子

——读《空军飞行员》(圣-埃克絮佩里)。 像大多数人一样,我对圣-埃克絮佩里的印象来源于他那篇家喻户晓的《小王子》。可惜那时候年龄尚小,理解有限;而各类阅读理解、名著导读等等又早已把《小王子》反复解读,将它的深层含义解剖出来并以标准(却并不诱人)的方式呈现在了面前。因此,我真正为圣-埃克絮佩里的文字所震撼到,是偶然读到他的《夜航》。虽然小说中所描述的航班🛩以死亡作为其失败的结局,但飞行员在坠毁前的最后一刻冲出乌云,在灿烂夜空下宛如流星🌠一般的谢幕,在我的心中留下了无法磨灭的画面。 ...

Python多线程和多进程的运行速度比较

通过一个图像合成视频的脚本案例测试了一下Python3在单线程、多线程和多进程下的运行速度。发现多线程可以一定程度上提高运行速度(将1个线程拆为4个线程,提速大约83%),但是不能达到完全的并行运算,据说是因为threading模块并不能真正调用多个处理器。在多进程下运行,可以接近完全平行的运算速度。 ...

Elimination of 3 years?
