The 30 second habit with a lifelong impact

Immediately after every lecture, meeting, or any significant experience, take 30 seconds?—?no more, no less?—?to write down the most important points. If you always do just this, said his grandfather, and even if you only do this, with no other revision, you will be okay.

Programmers At Work

The finest pieces of software are those where one individual has a complete sense of exactly how the program works. To have that, you have to really love the program and concentrate on keeping it simple, to an incredible degree.

Example of what not to do on a large scale.

WhatsApp is Different

This shows the peak number of monthly active users for a number of services/products over their lifetime. The data is from official sources when possible, otherwise the numbers are reported in press coverage; the methodology for calculating these numbers varies significantly and is often misreported (e.g., total users will be called MAU), but even only with directional data, the differences in scale are still clear.
