Why programmers work at night
A popular saying goes that Programmers are machines that turn caffeine into code. And sure enough, ask a random programmer when they do their best work and there’s a high chance they will admit to a lot of late nights. Some earlier, some later. A popular trend is to get up at 4am and get some work done before the day’s craziness begins. Others like going to bed at 4am. At the gist of all this is avoiding distractions. But you could just lock the door, what’s so special a...

The Story of W&L: China’s Great Internet Divide
Here’s an introductory quote from The Story of W&L, a tale of China’s great internet divide: China does not have one so-called “national internet,†instead there’s a great divide.

This is the story of W&L, two representatives of China’s great internet divide. T...

Why is single threaded Redis so fast
Redis is a high-performance, in-memory key-value database. According to official test reports, it can support around 100,000 QPS (queries per second) on a single machine. However, Redis uses a single-threaded architecture in its design. Why does Redis still have such high performance with a single-threaded design? Wouldn't it be better to use multiple threads for concurrent request processing? In this article, let's explore why Redis has a single-threaded architecture and still maintains its spe...

Speed Hashing
A given hash uniquely represents a file, or any arbitrary collection of data. At least in theory. This is a 128-bit MD5 hash you're looking at above, so it can represent at most 2128 unique items, or 340 trillion trillion trillion. In reality the usable space is substantially less; you can start seeing significant collisions once you've filled half the space, but half of an impossibly large number is still impossibly large. Back in 2005, I wondered about the difference between a checksum and...

Code reviews in the 21st Century
There's an old adage that goes something like: 'Do not talk about religion or politics'. Why? Because these subjects are full of strong opinions but are thin on objective answers. One person's certainty is another person's skepticism; someone else's common sense just appears as an a prior bias to those who see matters differently. Sadly, conversing these controversial subjects can generate more heat than light. All too often people can get s...

How to tell if this idea is a good idea.
Good Idea or Bad Idea?I’ve got an idea for a product. I’ve talked to some people. I know some people in the industry. I have been cold calling others. The idea is promising. The price point people have agreed with is about where I would like it to be. I’ve shown some mockups around and iterated on them. Now, I feel the need to start writing code because, well, I like writing code. And I’m comfortable writing code.But I see lean people.Steve Blank, Eric ...
