Computers exist to serve us, not the other way around. If it is not fast and reliable then it is wrong!

In Python, it's a trace back. In Ruby, it's a back trace. In Java, it's a stack trace. All we need now is a trace stack.

Some of my favorite stories selling what would become GitHub Enterprise early on was dealing with the culture changes back then. I had a number of large banks tell me — with a straight face — "how can you possibly have quality software if you deploy more than once a quarter?"

@vpatryshev @nikitonsky Well, now you have "11 separate tests, ~5x as much code, multiple helper functions and `beforeEach`s to avoid duplication, and more difficult to read."
English
@garybernhardt @nikitonsky I'd rather prefer 5ish-lines tests. If one check depends on another, there's something fishy.
English
Me at 25: Tests should be 5ish lines! One assert per test!
Me at 40: This test is 56 lines long with 11 asserts. If I broke it up, it would be 11 separate tests, ~5x as much code, multiple helper functions and `beforeEach`s to avoid duplication, and more difficult to read.
English
@triskweline Yep, and yet they're all also useful ideas... sometimes! The key is to make the gremlins work for you instead of you working for the gremlins.
English
Mind gremlins like that have compromised my code for decades:
- One idea per line
- Comments are a smell
- Law of Demeter
- Only immutable values
- Inversion of control
- Single Responsibility
- DRY (still fighting that one!)

If you force code into an arbitrary shape, you'll deform it in other ways that are often worse than just letting it be the shape that it wants to be. Sometimes a line should be 150 characters long; sometimes a function should be 150 lines long. But usually not.
English
The vast majority of tests that I write are small, with a single assert. But sometimes there's a complex story to tell, which leads to complex setup, and sometimes it's easier to tell that story by building the story up piece by piece, asserting as you go. It's fine.
English
@sjfloat I read it as admiration, not derision. Maybe you're right about them just meaning rhythmic sense, though it seems weird to me to say that as "he *is* [thing that keeps rigid time]". Either way, I think this was a really bad example on my part, for multiple reasons.
English
@garybernhardt Do they mean it in a derisive way? You can have a solid, regular rhythmic sense *and* be able to vary a tempo continuously. Rubato is a dying art. And click tracks have taken a terrible toll on popular music.
English
@freegroucho @exec_prog Yep, it's really counterintuitive. People often seem to think about it like a computer that they can speak to in natural language, but it's more like a creative but intellectually lazy intern that never gets tired.
English
@garybernhardt @exec_prog Yeah, AI/ML is not good at being 100% right. Its good at creating boilerplate starting points for code and writing projects. And for learning about a new topic.
English
@exec_prog (After 6 years without ever using a spell checker, there were 3.5 typos in the entire course catalog. There may be grammatical errors lurking, though; those can't be automated away in the same way.)
English
@mikaeilo @exec_prog I've tried grammarly before, but it suggested that I should do violence to my draft in various ways, so I don't bother with it. I only put the draft through ChatGPT to head off an objection to the post: I know that people will say "just use GPT" without knowing whether it'd work.
English
@garybernhardt @exec_prog I wonder what gramarly would report. In this specific case I think chatgpt didn't have enough training data to mimic a proofreader. And it doesn't understand the concepts you're prompting it with.
English
@SesGoe @exec_prog Somehow there was a smart quote in place of an apostrophe. It's not "wrong", in that it reads correctly, but it definitely wasn't intentional. Also I hate smart quotes.
English
@garybernhardt @exec_prog I'll be the first to ask:
How do you get half a typo?
English
Wrote a blog post (that I may not publish) about the spell checker that I just wrote for @exec_prog. As part of that, I asked ChatGPT to proofread a draft of the post. It ignored my instructions ("only report actual errors, not suggestions"). It also hallucinated one error.
English
I don't know what it is about Playwright in particular, but ChatGPT just doesn't understand it at all. I've asked it ten different questions today, and for every single one it hallucinated APIs. Then if I tell it that, it hallucinates another API. Then if I tell it that, it hallu

@smlpth But this tweet isn't about whether AI is good or bad; it's about claiming to know the future. twitter.com/garybernhardt/…
Gary Bernhardt@garybernhardt
If you read this as "[insert tool here] will amount to nothing"... no. I don't know the future any more than the people who dumped billions of dollars into WS-*. But I do know that I don't know the future, which is pretty important.
English
@garybernhardt With the level of your skills, you’ll be the last to be left behind by the AI revolution on our craft. It’s infinitely harder to get your level of mastery on all levels of the stack than learning to prompt an LLM or use an AI assisted IDE 😅.
English
I always listen to the confident, loud declarations about the future of programming (don't want to get left behind)! That's why I always start with a UML diagram, then let tooling generate aspect-oriented WS-* services, with the data stored in a network database.
