> I suspect best practices for "vibe coding" will end up like test-driven development: a proven method for writing better software that many engineers still choose to skip.

I’d like to see the proof for TDD; last I heard it slowed development with only minor reliability improvements.

I think it works only for people with a certain thought pattern, the ones that like to think everything up-front before doing anything.

Most people prefer to play around and make several crappy attempts and combine them until the whole is somewhat solved, then go over and polish it a little, and maybe then add tests and fix the behavior in place.

For this last group, TDD it's jarring, unnatural and requires a lot of willpower to follow.

It's not bad in itself, it's just not for everyone.

From TFA:

    Imagine the 3 AM on-call alert. The engineer trying to fix it might be navigating a section of the codebase they've never seen before, generated entirely by an AI. In this scenario, you can't afford to vibe it out or gamble precious minutes while an AI agent attempts a fix. You need ground truth, and you need it fast.

This is where it breaks down for me. If you trusted the AI to do the code, why don't you trust it with the on-call?

Why automate the fun part and keep a human for the shitty part?

I don't really get the reasoning behind all the hype, or better said: I kinda do, but it's more of a knee jerk reaction or essentially FOMO.

What makes me think this is a bubble is the amount of emotion behind the decision making process (plus the fact that almost nobody is making a dime with this so far).

I think the article underestimates how much intent can be grasped from code alone. Even without comments.

Humans (and I strongly suspect LLMs, since they're statistical synthesis of human production) are fairly predictable.

We tend to tackle the same problems the same way. So how something is solved, tells you a lot about why, who and when it was solved.

Still, it's a valid point that much of the knowledge is now obscured, but that could be said too of a high employee churn organization.

> My goal here is to develop an intuitive sense of comfort with the behaviors of these stacks. If I succeed, you will not just understand that the physics allows the stacks to be stable, but you will feel that it is proper and just.

I love this kind of writing. It feels like the author is excited to bring me along on a journey — not to show off how smart they are. In this way it reminds me of Turing's original paper that introduced his "computing machine". It presents a fantastically deep topic in a way that is not just remarkably accessible but also conversational and _friendly_.

I wonder why so little modern academic writing is like this. Maybe people are afraid it won't seem adequately professional unless their writing is sterile?

It's really hard to achieve. It takes an awful lot of work and being able to put yourself in the shoes of somebody who doesn't know everything you know.

It doesn't seem like it would be all that difficult to allow that form in a backwards compatible way. Why hasn't this happened?

juancn · 4 days ago

Not sure. It seems a fairly basic syntax change and it could even be easily made backwards compatible.

Now we need to get the ANSI SQL committee to standardize it ANSI SQL 2027 or some such.

SQL shows it's age by having exactly the same problem.

Queries should start by the `FROM` clause, that way which entities are involved can be quickly resolved and a smart editor can aid you in writing a sensible query faster.

The order should be FROM -> SELECT -> WHERE, since SELECT commonly gives names to columns, which WHERE will reference.

You could even avoid crap like `SELECT * FROM table`, and just write `FROM table` and have the select clause implied.

Never mind me, I'm just an old man with a grudge, I'll go back to my cave...

Other than the strange scrolling (works on my iOS Safari, but why?) this is very well done. Clearly a lot of thought went in to it, many nice details in the assets and overall presentation. The illustrations of the drivers and their cars are separate layers than move ever so slightly. That amount of care isn't strictly required but it was done and my day is better for it. Thanks.

No affiliation, no interest in F1, just basking in good work.

Finally, the v12 Ferrari engine sounds the best. Fight me.

juancn · 17 days ago

I like the Renault V10 better, although the Ferrari V12 is a close second.

I think even Hamilton agrees! https://www.youtube.com/watch?v=_I0R5yZ80rA

“I think a repetition of 1929 is most unlikely. But obviously economic and human affairs go in cycles. It could well be that some time there will be a collapse. I’ve always thought that if we did have one, it would be the dollar, not the stocks.”
