The benefit of values over classes is that they do not hide machinery. If you x.getY(), is that a member access, a computed value, or a network fetch? Will it lazy-instantiate a log4j singleton and start spamming my IDE with red text?

I read the article. Parent's comment about automation is spot on. TFA didn't describe any GUI interaction in detail, or even suggest that there was a way to achieve these goals without needing a meatbag to physically interact wi

It's too much of a stretch to call null an escape hatch, or to pretend that code reviews will somehow strip it out. The OpenJDK HashMap returns null from get(), put() and remove(), among others. Is this just because it hasn't bee

It made no reference to the 'shared' in 'shared state'. No mention of asynchrony, multithreading, or the race condition that TFA encountered.

This is one of those cases where software transactional memory really shines. You can often take the naive solution and it will be the correct one. Your code will looks like your intent. TFA's first attempt: async def drain_reques

It's the definition of simple that's the problem. For any definition of simplicity you might have, someone has an equal and opposite definition. Take these two alternatives: class UserService { PostgresDatabase db; }

If you spend your life talking about bool having two values, and then need to act as if it has three or 256 values or whatever, that's where the weirdness lives. In C, true doesn't necessarily equal true. In Java (myBool != TRUE)

I was recently switched from Java to C# at work. Initially I was impressed by the null detection. Then I found out about defaults. Way worse than null. C and Go can demand a bit of ceremony with manual error checks. Things get bad if you

TIL about Monofunctor. Pretty nifty. It's for cases where your type is a container of something (as opposed to anything ). I.E. you can .map (or .Select if you're .NET-inclined) over the Chars in a String, but not some other
