Still trying to learn how to think better.

Cindy Sridharan quoting Joe Armstrong:

We should identify the error kernel. The error kernel of a system is that part which must be correct. That’s what the error kernel is. All the other code can be incorrect, it doesn’t matter. The error kernel is the part of the system that must be correct. If it’s incorrect, then all bets are off. The error kernel must be correct.

John D. Cook:

The rule of three gives a quick and dirty way to estimate these kinds of probabilities. It says that if you’ve tested N cases and haven’t found what you’re looking for, a reasonable estimate is that the probability is less than 3/N. So in our proofreading example, if you haven’t found any typos in 20 pages, you could estimate that the probability of a page having a typo is less than 15%.

Hashing syntax trees and storing them directly in a database is very interesting. I’ve long wondered what will come after the grab bag of text files approach we’ve been using to date.

Embrace the power of compounding.

Now you can learn them too.

The first time any of the above happens on your watch, it’s always new and hard, no matter how many books you’ve read on the topic. But the fifth or tenth time or 20th time it happens, you’re no longer freaked out. You realize that you’ll be fine.
