看看 project euler 的第一道题:
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
用 python 语言写出来是:
print sum(i for i in xrange(1, 1000) if i % 3 == 0 or i % 5 == 0)
This is the first edition of what is expected to become a recurring series on InfoQ. The idea behind this minibook is that a number of InfoQ articles and interviews which deal with a particular topic (in this case, REpresentational State Transfer, or REST) are combined together to provide a detailed exploration suitable for both beginners and advanced practitioners.

Both are of the same general opinion that I am abandoning testers and that Google is not a nice place to ply this trade. I am puzzled by these comments because nothing could be further from the truth. One such negative comment I can take as a one-off but two smart people (hey they are reading this blog, right?) having this impression requires a rebuttal. Here are the comments:
