I've legitimately seen one project that basically says to do that, but with "your ai agent". At least piping to sh is deterministic and, you can pipe to a filw and check the script

It's a fallacy when there is no cause and effect for each step. This, however states the steps.

AFAICT, actually manipulating the AST, which then in turn allows you to implement your own language features, inserting additional debugging info, memoizing a function by just wrapping it in a macro, or optimizations based on domain knowledge.

A bit off-topic: I occasionally see that triple ^H on HN posts: what does that actually indicate?

I appear to have misread some things. I'll have to re-research the stuff.

AFAICT, municipalities get paid to put up the cameras, which isn't federal, so flock can then use those cameras to freely gather data and sell it to police

I personally find old reddit on mobile more usable than both new and the app version.

> this isn't a one-off use, I don't want an app to pay parking meter once and never use it again

Just today I ran into a parkingmeter that was covered up in favor of ONLY allowing to pay via app. Which I find horrendous. (austria, for context)

> To most modern users, web browsers kinda suck if they don't know URLs. For example, if they want to find an item they saw on Amazon, searching it in browser history just sucks compared to the in-service search.

And, more and more, browsers are trying to hide the URL as much as possible. Which is REAPLY annoying.

> This is why I don't like Reddit pushing an app and breaking/limiting the mobile website. It's just not how I want to use it at all.

As with many reddit problems, old.reddit.com is a pretty universal fix.

> - I can see when it gets updated (versus a website that gets updated every time I load it). For security reasons it's better, I can even verify my app with other people online and make sure we run the same thing.

in many cases this is no longer the case. Discord, for example, has introduced capabilities to update parts of the app without goung through the play store on android, same with youtube. Which they obviously use to enshittify things against your will.

Wait, so in america you can literally just click one button on a product and instantly have it paid for and set for delivery?

That seems rather accident prone.

On private/community hosted/moderated servers my experience was that cheating was mostly a non-issue. Only with the advent of forced matchmaking/only official servers and such has it become a real problem.

If the donations were to the opposite end of the political spectrum, do you think there would be a similar amount of backlash?

or:

1: the media has a vested interest in only reporting a certain slant, because it involves criticizing the media

2: because the media is the only source deemed reliable, that slant becomes the truth

Mostly by looking at the calling site where the code is already used and the calling site where I want to reuse it. If both of those mean the same (calculate the tax on x products, for the purpose of applying to the shopping cart, vs for applying to generating reports) then I'll reuse it, if it can be achieved without adding stuff like flags, in most cases. In other cases, it just looks the same (sum some field + calculate a percentage of that, for example, for discounts vs taxes on products) where it's obvious that they don't mean the same. (Though, I do heavily rely on a good type system to deal with future evolutions of that copied code)

TL;DR: Vibes

My metric for that is "does that code MEAN the same thing" or "does it just look the same". Has worked quite well for me so far. I frequently find myself making a copy of some code rather than adding a parameter (most commonly done with code that would get some flag added)
