[讨论班]做技术报告的时间控制

听众集中精力的时间是二十分钟左右。
所以一般的技术报告时间不超过四十五分钟。
要详略得当，一个博士四五年的工作也都在四十五分钟讲完。
宏观的技术介绍，2:1，45页ppt，20分钟讲完。比例越高越难讲，既要节奏慢，又要把内容讲完。
技术讨论，1:1

内容的选择
要focus到最关键的技术上，不要连实现细节都讲，生怕自己做的东西别人不知道。

第一个one-liner的程序

不得不说，python真是太强大了。

Euler Problem 16

2¹⁵ = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26.

What is the sum of the digits of the number 2¹⁰⁰⁰?

Solution:
print sum(int(i) for i in str( 2 ** 1000 ))

Re: [Readings]genius?

Some Quotes:

So what does create genius or extreme talent? Musicians have an old joke about this: How do you get to Carnegie Hall from here? Practise.

And as cellist Yo-Yo Ma once said, the most proficient and renowned musicians are not necessarily those who outshone everyone as youths, but rather those who had "fire in the belly".

So is the ideal of innate genius dead? If not, should we kill it? Certainly a clear-eyed analysis shows that "genius" is really a set of exceptional skills cultivated through disciplined study. We should probably shelve the notion of genius as an innate, almost irrepressible gift and speak instead of expertise, talent or even greatness - terms that hint at the work underlying supreme accomplishment.

Granted, this isn't as fun, and recognising the work factor is sobering. It is disappointing to realise all your mom's blather about how smart you are doesn't mean jack, and that you have to work demonically regardless. But as something to believe in, genius is not looking so smart. You want to play the big stage, you got to put in the time.

[Digest]论语

子曰：君子食无求饱，居无求安，敏于事而慎于言，就有道而正焉，可谓好学也已。

子曰：知之者不如好之者，好之者不如乐之者。

樊迟问仁。曰：仁者先难而后获，可谓仁矣。

coding practice - Project Euler

总是觉得自己代码写得不够多。
TopCoder的SRM做起来还有难度。
先从http://projecteuler.net/index.php开始吧。

Practicing Python

There's many ways to get better acquainted with Python. If you like puzzles and/or math, then there's two ideal resources for you:

The Python Challenge is a series of riddles that can be solved with (usually short) Python scripts.
Project Euler is for the more mathematically inclined and consists of a ever-growing set of problems that will probably test your problem solving skills much more than your programming skills. Nonetheless, if you need an excuse for programming, and this is your type of thing, then you should have fun.
