@hhrmatata
我现在需要初始化一个五维list ToT，这两种写法都很丑陋啊。。

Replied to a topic by csslayer › Linux › 对开源项目的抱怨的和参与的比例总是感觉让人失望

我觉得氛围是个问题呢，周围即使做同学开源的同学也不是很活跃，想起步的时候找不到线下组织

Replied to a topic by glume › 问与答 › 求一本量子力学方面的书

取决于lz对知识的需求有多深，lz的数学功力以及lz的英语能力，不同的书适合于不同的情况。
《上帝掷筛子吗》是一本很有趣的科普读物，引人入胜，适合培养兴趣；
费恩曼物理学讲义需要一定物理基础，智商和时间（确实不宜懂），但是读完之后效果斐然，同时对数学的需求不是特别深。
正规教材，就很考验数学功底了，最浅是偏微分方程与复分析，最深能用到一些特泛函知识，可以先看一本数学物理方法http://book.douban.com/subject/1182629/。
中文教材我当时用过赵凯华老师的教材http://book.douban.com/subject/1509468/，以及高等教育出版社的蓝色皮的（找不到了，也可能是我记错了）。觉得写的至少对入门还不错。
英文教材，当时学长推荐的是: David J. Griffiths的，http://book.douban.com/subject/1706283/。还有一些blog推荐过Dirac的或者其他的。
如果英文够好又不想话很多时间的话，ls的coursera的课挺不错的。

另外，lz可以搜一搜别人写的荐书blog，学数学物理的都喜欢写文章评书，就跟学CS的喜欢写blog一样，网上有很多这样的帖子。

好运~~

Replied to a topic by soho176 › Python › 用python 做爬虫，抓取网站，在抓取的过程中会碰到重复的网址，随着抓取网址的越来越多，网址库越来越大，如果每次爬到网址都去网址库对比一下是否重复，这样的结果就是效率越来越低了，有什么办法或者算法提高过滤重复网址的效率？

很大的话，一般用bloomfilter, 如果再大或者是分布式爬虫的话就需要更高级的东西了。
PS：似乎还可以同时考虑做simhash，找出重复页面。
