@antirez i agree, the art is the decisions and work that went into building something of enough quality to build on top of. redis and its api is a great example!

1. When you write something intended to be read by an important person, go through it and cut every unnecessary word.

2. The reader of anything you publish is an important person.

every few years i re-read “The Martian Principles for Successful Enterprise Systems” by Ronald Mak. Such great advice for building enterprise systems, still holds true in 2026.

@mitsuhiko you should — learning lisp and applying what i learnt to python was such a breath of fresh air coming from enterprise java

Mark Twain's aphorism about brevity in writing applies to software engineering as well. It goes something like this: "I didn't have time to build a simple system, so I built a complex one instead".

The basic software design question: this feature is going to be hard to implement. What would the design need to be to make this feature easy(-er)?

[tobi lutke @tobi]

As @dhh said so well: complexity is a temporary bridge towards discovering simpler solutions. It's necissary for innovation, but needs to be removed once the picture is clear.

I'm thrilled that our industry is starting to celebrate this type of work again!

during a code review, if you leave a nit and your nit is fine to be ignored don't leave it

you clutter the pr
you distract from any real issues
your preferences are just that, stfu and make a prettier / eslint / clangformat rule and move on with your day

If you want an electrician, don't hire the entire construction team.

Because the #1 rule of dependency management: "Depend only on what's needed"

It's simple, and your favourite IoC container mostly likely breaks it.

@hacklew this is great! 💯

learning React with ChatGPT

"does useEffect add the lambda function to a queue?"
"is setState similar to the concept of a 'lens' in functional programming, but queued against a component that will be rendered?"

I know the questions are wrong, but are helping my learning path

My #TDD in #OCaml:

1. Write 400 LOC non-stop.
2. Fix all compiler errors.
3. Run. It works.
4. Add 60 LOC of unit tests to cover edge cases.
5. Tests found errors. Fix them.
6. It works perfectly.
7. Drink a glass of fresh orange juice. Life is great.
