Stolen package

Filed under: Real — liyiwei @ 4:45 pm

I noticed a missed delivery slip near my front door. As before, I filled it out for redelivery without requiring signature, but the package never came and the staff could not find it in their office. Due to its content, I guess the package has been stolen. I did not keep a copy of the delivery slip since the process has worked before a few times.
Lesson learned: keep the due diligence and never let my guard down.

The 99% invisible city

Filed under: Real — liyiwei @ 10:54 pm

This is a fascinating collection of short articles about how people build and interact with our environments. Initially I wondered why the book used illustrations instead of photographs, but as I read on I realized that this choice better fits with the design of the book, set in beautiful yellow-black color scheme and typography.

Common law versus civil law

Filed under: Real — liyiwei @ 12:12 pm

Quote from here:

The main difference between the two systems is that in common law countries, case law – in the form of published judicial opinions – is of primary importance, whereas in civil law systems, codified statutes predominate.
But these divisions are not as clear-cut as they might seem. In fact, many countries use a mix of features from common and civil law systems. Understanding the differences between these systems first requires an understanding of their historical underpinnings.

So, common law is data-driven while civil law is procedural.
