Keyboard latency
We can see that, even with the limited set of keyboards tested, there can be as much as a 45ms difference in latency between keyboards. Moreover, a modern computer with one of the slower keyboards attached can’t possibly be as responsive as a quick machine from the 70s or 80s because the keyboard alone is slower than the entire response pipeline of some older computers.

Is There a Cryptocurrency Bubble? Just Ask Doge. - NYTimes.com
Imagine that a friend is building a casino and asks you to invest. In exchange, you get chips that can be used at the casino’s tables once it’s finished. Now imagine that the value of the chips isn’t fixed, and will instead fluctuate depending on the popularity of the casino, the number of other gamblers and the regulatory environment for casinos. Oh, and instead of a friend, imagine it’s a stranger on the internet who might be using a fake name, who might not actually know how to build a casino, and whom you probably can’t sue for fraud if he steals your money and uses it to buy a Porsche instead. That’s an I.C.O.

Applying the Universal Scalability Law to organisations | the morning paper
1. It’s really important you learn to delegate effectively and to choose carefully the things that you do get involved in.
2. As the organisation grows, strive to keep the number of stakeholders that need to be involved in any decision down to a minimum
3. You need to keep a strict handle on how many things you’re involved in concurrently; your natural human instinct to be helpful to everyone who asks you to do something for them, or to contribute to their project, actually isn’t helpful at all. (Nor is your desire to control / influence everything if you’re wired that way).
