Of course, to be completely fair about my toolkit, standard Scheme can sometimes lack the heavyweight, “batteries-included” ecosystem required for massive enterprise production compared to the JVM.

I was thinking the whole time, "this person would _love_ Clojure".

I used to use it, like over 20 years ago! Mozilla Suite was too slow for my taste and I only reached for it if Dillo couldn't render a page :)

IIRC I stopped using it when Firefox ("Phoenix" at the time) was released.

I've also worked with CSV (barely) and SVN (more extensively) and I was blown away by Git.

You can have real branches! Many of them! You don't have to manually merge them! It's decentralized, you can have multiple origins, it lets you work offline! The list goes on and on.

There were many compelling reasons to switch to Git. But for all the articles about jj out there, I've never read any compelling reason to switch to jj. "It easier", "the commands are somewhat more ergonomic"... that's all?

I think it looks nice, but:

- Scrolling is unbearable on Firefox/Android.

- The icons are way too "noisy" I would remove them. Also, posts without icon look "misplaced".

Other than that looks pretty nice. The dark mode is awesome. Don't let the angry mob bring you down ;)

I had to laugh out loud when I read that sentence.

Really? I write code to pay my bills and sometimes just for fun.

Trying to do everything "the most optimal way possible" is going to get in the way of actually getting stuff done.

"Why do we code? To prematurely optimize all the things".

Yes, I was wrong on several levels.

First and foremost I was wrong thinking that I was smarter than others — that's not even how intelligence works.

Second I was wrong being so stubbornly pro-tabs / anti-spaces (for example). It doesn't make that much of a difference, so there's no point in being so passionate about it.

And third I was wasting everyone's time (and my persuasion powers) by not choosing my battles more wisely.

My suggestion would be nowadays: let's choose a popular style guide, set up a linter and be done with it.

I did that when I was young and naive. I'll tell you why I did it.

I thought I was very smart. Like, really really smart, maybe the smartest programmer in the team.

And as such my opinion was very important. Maybe the most important opinion in the team. Everyone had to listen to it!

That is all. Also, I was wrong.

Yes, you are technically correct and yet absolutely irrelevant to the conversation, just adding meaningless noise.

Also, there are many linters that also do formatting, blurring the "line" you're pointing at.

I’d say it’s more spreading knowledge around

How is it spreading knowledge around? A lot of times it gives half backed answers and a lot of beginners are using it while learning. That's not a good mix in my opinion.

I've been helping someone who's learning programming and I've had a look at their code. All of it is vibe coded. And the vibes are nightmarish, I don't think the AI is helping at all.

The only thing it's useful for is sparing expert programmers some tedious work, that's my perception as a programmer.

But UIs are not pure functions, they have a deeply effectful nature, and being reactive all those effects are highly “situated” if you will (to use Rich Hickey’s word).

Oh, but we do this in ClojureScript the whole time.

You can express events and actions in pure functions as data and then take care of the effects outside of the core of your application.

A great example of how to do this is the "re-frame" framework [1] [2]. The documentation is also a joy to read.

An example of this impedance surfacing in backend programming is a nontrivial map/reduce pipeline. What is the shape of the document at stage six?

There's many ways to find that out in Clojure/Script. There's the built-in `tap>` function [3] which can be used for debugging. You can use that to visualize complex data with Portal. [4]

    (defn inspect
      [coll]
      (doto coll tap>))
    
    (->> coll
         (map this)
         (inspect)
         (filter that))

He got famous because of "redux" and "hot module reload" and then he got hired by Meta and started working on react.

This was before the hook era.

The "zones" are way too big.

For example working in west Germany is quite different to working in east Germany. The same goes for north and south Spain, north and south Italy, and so on.

copy pasting chunks of code from one place to another and then modifying those chunks

That's not how you program. I've never seen anyone programing in this way unless they were just starting.

Edit: if you find yourself copying chunks and modifying them, you probably need to create an abstraction. Don't mean to be rude, just honestly that is my personal experience.

In my last gig we had exactly the same stack (WC without the shadow dom part + just lit-html) and it's great.

The best part is not having a dependency hell situation every other week.

Yes, that first part was not. But the article continues like this:

- they use that credentials to make a commit adding malicious code to the CI pipeline

- The rouge pipeline job adds their public SSH key to the `.allowed_keys` file in the production server

As the pipeline is run automatically on push, they get ssh access to the remote server.

That is the "CI / CD Pipelines" bit. That being said, it's a bit underwhelming, because given the title I though they were going to exploit a bug in the CI/CD software itself. I don't know if I'd call that "exploiting" CI/CD software.

From TFA:

A surprising number of websites still expose their .git directories to the public. When scanning for such exposures on a target, I noticed that the .git folder was publicly accessible.

[...]

With access to .git/config, I found credentials, which opened the door to further exploitation. I could just clone the entire repository using the URL found inside the config file.

The URL with credentials was found in the `.git/config` file, defined in the [remote "origin"] section. This is the way they won full access to the repo.

I find "removing" or resetting styles kind of hacky.

Another solution might be packing the map in a shadow element so that it doesn't get affected by the page CSS.

I think it's kind of important to be consistent about case because if not, people will trip when typing, it's annoying and might even cause bugs.

One thing I agree though, it's a waste of time to discuss about it. That problem is best solved with automatic tooling / linting. In the editor, git hooks and CI.

But if you and your colleagues don't have a problem with it, then I guess it's fine.

There was a great refactoring chance in the example where the cache was removed.

That is, extracting the caching logic from the API call logic.

Caching could have been a more generic function that wraps the API call function. That way each function does exactly one thing, and the caching bit can get reused somewhere else.

Instead, this weird advice was given: changing behavior is bad refactoring. Which is weird because that's not even what we call refactoring.

Edit: removed unnecessary negativity.

A refactor does not change behavior, period. By definition.

If something changed, it's not a refactor. It's a change.

Like in the example where the caching was removed: NOT a refactor.

Ore where the timeouts for the requests were changed: NOT a refactor.

The definition of refactor: change the structure of the code without altering the behavior.

It's like saying a crash is a bad landing.
