What's a good recent example of hype-driven software? The only good example I can think of is MongoDB. All the other hyped techs in recent memory I can think of were all objectively good: Nodejs, Reactjs, Docker, Kubernetes, etc. In th

Nodejs is single process, single thread and single core. Chrome used to run different tabs as threads of a process but that ended since Spectre and Meltdown. Back to single process since then. async IO creates a thread servicing that IO

Javascript doesn't "need" dependency injection because modules are objects, and you can mock those directly by replacing what they reference to. Very similar story in python. You could say people do DI in these dynamic langua

- If your code base utilizes dependency injection to make the code more "testable" with mocks, you are making the code 10x worse. There are other ways to make your code more modular without injecting new scope, logic and apis

Urine is recorded to being used for whitening teeth since at least ancient Egypt. I always thought they used something like a swab for it though, but you can be sure someone out there had the idea to use it as mouthwash lol.

First time I hear XMLHttpRequest was a mistake. No one is going to sit through a full-page reload on every form validation. Even intermediate solutions that merged (hacked) client-server state failed too. APIs are just better.
220.
by bernawil 7y ago
People need way more validations than html5 elements can provide. They need CC number validation. Validations that depend on the content of sibling elements. And they need it to display in custom ways like internationalized or whatever.

In my experience if the application state is overly complex then that is a result of the design, and that usually leads to a bad experience for the user. Though it is possible to overengineer this, you're probably underestimati

I personally hate when official documentation uses badly applied approaches because it will be invariably be quoted as source for some "best practices" argument at some point. That's clearly a use case for interfaces and type

How is that particularly functional? In Haskell the same example would be approached at type-level using type classes, something extremely similar to using Interfaces. I guess in a dynamic functional language you'd probably avoid doing

That's how rules/law work. If they'd let people enter 2 years on a tourist visa, for every person like you they'd get 100 with the intention to settle. So better ban it outright.

It's like a museum of problems. Waves of solutions that became problems after. The culture of code generation before the culture of XML configuration.

Isn't the real problem that Ruby's "magic" a lot of the time relies on monkey-patching stuff? I mean, Javascript's modules also are dynamically executed and then returned as a singleton module object (also cached, s

I think these languages are thriving in the cloud because they not only have a favored concurrency model, they have it mandatorily and so they spun a cohesive ecosystem. Take Java for example. You can make an event loop and use it on a web

by bernawil 7y ago
It's the concurrency model. The industry has decided threads just don't scale and it's doing away with the two most popular languages that rely on multithreading (Java and C#) and favoring NodeJs (event loop), Go (goroutines)
