Yes, no (built-in) AI is now a feature
-
To be clear, GPT's suggestion to drain input from the server side of the socket was the actual solution. My code worked completely after that.
The suggestion to avoid partial writes was a sound one. I was under the mistaken impression that Java does its own retrying and partial writes therefore can't happen. But this was not the real problem; it was only incidental.
Although GPT finally did give me the actual solution, I'm still calling this an epic fail, in light of the vast volume of utter crap that both bots threw at me.
As I said before, it's clear that they were both just making s**t up, had no clue, and accidentally stumbled upon the correct answer.

I would like to add that both bots tried to convince me to vastly increase the complexity of this tiny HTTP server by adding Content-Length, response chunking, and more thorough request parsing.
The whole point of this HTTP server, as should have been obvious from the minimalism of its code, was to serve one file at one URL-path with as small an attack surface as possible.
AI loves unnecessary complexity, and that is very dangerous security-wise.

Using duck.ai is great for simple requests. I find >200 line prompts challenge it quite a bit.
I am unfamiliar with Java (been many decades since I cared about Java - I have no use for it currently) but I am going to see what my agents do with it

Yes, I am familiar with that! DRY is sometimes a foreign concept to agents - they need reminding.
This is why "vibecoding" is no replacement for programmers
On a tangent Bruce Schneier has an interesting take on this (Bruce was a heavy sceptic of "AI" in 2022, I think it would be fair to say he has adjusted his views).

I think the point, Greg's in the video, and mine here, is these are tools and need to be wielded. Careless use has bad results
Careful use increases the reach of the user
The problem with this is that AI itself actively encourages careless use, in two ways:
1. It creates the illusion of being easy to use. Ask it to write some code for you, and it does so. Only if you're both skilled and vigilant will you notice everything that's wrong with the code.

2. It kisses your ass. It appeals to your ego. It encourages you to use it more.
That behavior is downright manipulative, and reminds me of con artists and drug dealers.
I avoid AI not only because I find it largely useless, but also because I consider its manipulative behavior extremely dangerous. If I'm exposed to it long enough, I don't know if I can stop it from successfully manipulating me. Probably not.

This is a **huge** problem. It does lower one of the barriers of entry into the software producing world - it can cut a lot of code quickly, it will compile, it will run sort of like what you want.
All of the other barriers, including but not limited too: Understanding the problem domain, logical thinking, organised thinking... It does not help with those in such an easy way.
Yes

Yes
Yes, and that's the hard part of programming anyway.
I don't need help writing code. I have perfectly serviceable hands and keyboard with which to do so.
It would be helpful if AI could reason about code and invent a novel solution to the problem at hand…but if it can do that, then it also can, and probably will, go full Skynet and kill us all.

I feel so old! Yes, I am irritated by the subsequence of the responses. But I think it is going out of fashion.
The "encourages you to use it more". Anything that produces results is like that, true? I do not get the sense that I am being manipulated, like I see from, say, the effect of Youtube on my four and six year old grandchildren (shiver)

This is the KISS principle, not DRY. But yes, bots seem pretty bad at DRY too.
And to be fair to bots, a lot of human programmers are also quite bad at both of these principles. “Minimize attack surface” may as well be a foreign language to most people.
Which I guess explains why bots behave this way. Because that's who they learned from.

This is where I urge you to try.
The AI agents are very good at assembling the boiler plate, then, with guidance, honing that into useful artefacts

I suppose Schneier is correct that you can use a bot if nobody cares how you get the job done and nobody cares if the job is done well. Which, sadly, is and has long been the case at a lot of companies.
But that is not my situation. My code has to be good. There will be serious consequences for me if it produces wrong results or if it causes a security breach. Using a bot in this situation is an exceedingly bad idea.

No. I am of course encouraged to use a tool that works well, but I'm encouraged by the results, not by the tool itself. If the tool itself encourages me to use it more, then that's more like a drug than a tool.
Especially if, as in the case of AI, the tool actively manipulates me with spoken words, like a drug dealer or con artist would. I consider drug dealers and con artists dangerous for the same reason.

And yeah, if you see your children being addicted to YouTube, then just remember that bots are trying to do the exact same thing to you.
Maybe they'll succeed, maybe they won't, but they are trying, and the only 100% certain way to defend yourself is to not talk to them.
(I actually don't find YouTube particularly addictive, personally. But that's just me, and perhaps that's just because it has no content that I would find addictive.)

That site doesn't work without JavaScript, so I'm gonna pass on reading it.
Anyway, if you have a boilerplate problem, then you need macros, not AI. Macros are reliable and maintainable; vast volumes of repetitive code, whether AI-generated or copy-and-pasted, are not.

Nope, that's a fail.
The thread gets interrupted after 30 seconds, but ECONNRESET happens instantaneously.
Partial writing didn't happen.
The interrupt is intentional and not optional. The server is intended to only run for 30 seconds—long enough for the user's browser to start up and fetch the page—and then shut down, which is what the interrupt achieves.
The interrupt also prevents malicious clients from holding open a connection indefinitely.

The bot is correct that the serveThread fails to catch InterruptedIOException. I hadn't added that yet, but it is there in the production code.
And the bot is correct that partial writes aren't being handled properly.
But that's it. The bot has failed to correctly explain what's happening, failed to fix the bug, and introduced a security vulnerability. And it did so with the utmost confidence.
