Show HN: Middleware for running autonomous AI coding agents in sandboxes
We've built what we believe is the missing piece in AI development: an agent-agnostic middleware infrastructure that lets AI coding assistants run in parallel sandboxed environments.

Key technical features:

- Dynamic workspace provisioning with parallel sandbox environments
- Connect to the workspace with VS Code
- Full system interaction capabilities (shell, Git, LSP)
- Resource-optimized cloud infrastructure
- Enterprise-grade security and access controls

Why we put together this proof-of-concept:

Current AI coding agents are limited by working in single files or environments. We have a vision to enable agents to:
- Spin up multiple sandboxes to test different solutions simultaneously
- Access full development environments, not just single files
- Run real-time tests
- Scale compute resources efficiently

Our implementation addresses the core issues outlined in our CEO's recent analysis of AI coding infrastructure (https://go.daytona.io/ai-coding).

This is a proof of concept demonstrating how AI agents can work with proper infrastructure support. We're looking for feedback from the HN community, especially:

- Developers building AI coding assistants
- Teams working on development environment tooling
- Anyone interested in AI agent infrastructure standards

The code is open source and we welcome contributions. Happy to answer any technical questions!

How do you manage resources like links, PDFs, and videos?
I've found myself in need of a better way to organize resources like links, PDFs, and videos—a place to "dump" everything and be able to search or filter it later in a smart and productive way. I’ve seen all the hype around tools like Notion or Obsidian, and while they seem powerful, I’ve never been a fan. To be honest, they feel overwhelming to me.

Historically, I've gotten by with simple notes in my phone’s default app or a notes.txt on my computer. It’s low effort, and for the most part, it’s worked. But now that I’m juggling more resources, I could use something more organized, ideally a tool that could categorize, tag, and organize content intelligently without needing a ton of manual input.

I know there are ways to do this in Notion or Obsidian, but the setup requires a lot of curating and cognitive effort. That might be fine if I’m studying something in-depth, but at the moment, I just need a straightforward way to manage resources with minimal upkeep. A system that automatically tags, categorizes, and makes everything searchable by topic, subtopic, or type would be ideal.

Does a tool like this even exist? With so much advancement in tech, I figure something might be out there that does this intuitively. I’d love to hear what others are using and whether any tools have solved this problem for you.
Unity has literally the worst implementation of C# out there right now. Not only is it running Mono instead of .NET (Core) but it's also not even using Mono's generational GC (SGen). They have been working on switching from Mono to .NET for years now because Mono isn't being updated to support newer C# versions but it will also be a significant performance boost, according to one of the Unity developers in this area [1].

IL2CPP, Unity's C# to C++ compiler, does not help for any of this. It just allows Unity to support platforms where JIT is not allowed or possible. The GC is the same if using Mono or IL2CPP. The performance of code is also roughly identical to Mono on average, which may be surprising, but if you inspect the generated code you'll see why [2].

A properly seasoned cast iron pan can be non-stick but the temperature has to be right, you need shortening, and you can't just put any amount of food in it at any temperature.

Stainless is can do the job too, but temperature and shortening is even more important. There's a much tighter window of temperature that it works at. You do the "water drop test" to determine that it's ready. See youtube for an infinity of videos on how to check the stainless is at right temperature!

I've given up on non-stick pans. They're semi-disposable because the don't last very long and you don't want to use them at high temperatures. All it takes is a little bit of skill to never have to use non-stick teflon pans.
Maybe it also explains why so many positive comments in HN. Probably a biased sample.

I'd like to hear some disadvantages of using Astral in this point of time and how they plan to improve.
> The scientific method is sound != every experiment that claims to use the scientific method is sound

Sure, which is why I asked OP to define what they meant by "scientific method". The statement doesn't mean a whole lot if we're defining "scientific method" in a way that excludes 99% of scientific work that's actually produced.
If you're always looking up but never looking down it becomes hard to appreciate things.
That's still pretty much cross-platform for all practical purposes, as it supports far more platforms than most softwares anyway. After all cross-platform only means that it runs on multiple platforms, not on all possible or even technically feasible platforms. Being cross-platform usually means a much easier porting but that porting still has to be done somehow.
What about hardware-configuration.nix?

"we've replaced X% of our workforce with AI"

Most likely what is actually happening is that the X% of workforce you would lay off is being put to other projects and Google in general can take on X% more projects for the same labor $$. So there is no real reason to make that particular "replaced" statement.
To me, programming assistants have two usecases:

1. Generate unit tests for modules which are already written to be tested
2. Generate documentation for interfaces

Both of these require quite deep knowledge in what to write, then it simply documents and fills in the blanks using the context which already has been laid out.
Actually yes.

If you've never been falsely accused of cheating in an online game by people who can't tell the difference between that and getting outplayed, chances are you haven't played any multiplayer games long enough to get any good at them.
> Given that the car industry here in Germany opposed the (even much more moderate) tariffs...

Isn't the German car industry pretty much all-in on China, and thus dangerously exposed to any retaliation? IIRC, they have lots of factories there and depend on their output for a lot of their revenue. It would be pretty easy for China to shut them down or make life difficult them with some kind of pretext.

Boy, do I wish governments shared business's wise preoccupation with next year's numbers.
I used to work at a place that developed a DAW in the browser, and yeah, we used a WASM Ogg Opus decoder to save on storage costs for our sound library. We earlier had to have mp3s for safari devices. With opus being opus we really wanted to provide it for the majority of devices as well as our server side streaming, and being able to provide opus support for safari ourselves was a godsend.

Edit: Should note that our decoder was developed in house and I have nothing to do with the project OP linked to.

Until recently most fonts just used an oblique version of the main font as their italic. With the assumption that if someone wanted a "true italic" they'd use another font specifically for that. Italic and roman traditionally being two completely different fonts, not really one a variant of the other. Now "true italic" is becoming common again and it often has that cursive look you don't like.
A quarter of all new code? Of course. Especially if you include all "smart autocomplete" code.

When dealing with a fermenting pile of technical debt? I expect very little. LLM's don't have application-wide context yet.

AI is definitely revolutionizing our field, but the same people that said that no-code tools and all of the other hype-of-the-decade technologies would make developers jobless are actually the people AI is making jobless.

Generate an opinion piece about how AI is going to make developers jobless, using AI? Less than a minute. And you don't need to maintain that article, once it's published, it's done.

While there's a tsunami of AI-generated almost-there projects coming that need to be moved to a shippable and sellable state. So I'm more afraid about the kind of work I'm going to get while still getting paid handsomely for my skills, than ever being jobless as the only guy that really understands the whole stack from top to bottom.

Article is a big-ass non-sequitur.

> What is the ultimate long-term goal?
> Exploring and conquering all of the universe.

This is never really explained. The whole article uses this as a justification, but doesn't really explain why this is. It leads to a "nowhere" that is equally strong as the hedonism it denounces in my opinion.

> The boringness of existence without definite goals.

If you need external goals to feel non-boring, that's fine. But you are in some sense going to be a slave to those goals, and if another person has handed you these goals, you are a slave to them.

I am honestly fine without definite goals. There are common background activities and values, such as keeping myself healthy and strong so I can do what I want, and being friendly and helpful to others to make friends-good friends are pleasurable. But why "conquer" a universe when you can be happy with much less work? What are you going to do after that anyway?
What we commonly refer to as "plastics" are mainly chains of carbon atoms, whereas silicone is a chain of siloxanes instead.

Silicone is better for food preparation as it withstands heat better, has low toxicity (especially compared to additives used with plastic utensils), low reactivity, high resistance to oxygen, ozone and ultraviolet light, doesn't support microbes and repels water which is great for things like spatulas.

I don't get the AI link though. This seems to be entirely corporate mismanagement.

I had some investment in SMCI, but back in March my financial advisor, who usually wants to talk about all trades beforehand, called me to tell me he sold my SMCI because of reports of their financial statements being "fishy". "Usually, things like this signal the death of a company, because investors invest based on trust, and if you start lying to them they stop investing."

At the time I couldn't fathom a landscape without SMCI, over the decades I've bought hundreds of their servers and various other gear. At one point I had the better part of an aisle in a data center that was exclusively SMCI.

Yes, AI may have led to their fast rise in stock, but I don't see that it has anything to do with the fall.

This. Even FLAC support isn't great.
outlandish. i will get laws passed that require you to play and enjoy my game. how dare you, sir.
but isn't a characteristic function just "the" way to bridge the gap between sets, functions, and logic(? ...a 3way bridge!?)

I mean, it was useful for me to think about like a translation between sets and logic (this variable x is in the set xor not) into functions (a function f(x) that returns 1 or true whenever x is in set S)

how the heck is that a fourier transform!??
No, the difference in cost between central air conditioning (a heat pump that works in one direction) and a heat pump that works in both directions is negligable unless you're being ripped off.

The two biggest engines, Unreal and Unity, use a GC. Unity itself uses C#. C# is viable for games but you do need to be aware of the garbage you make.

It's really not that hard to structure a game that pre-allocates and keeps per frame allocs at zero.
It's an omega-6 toxicity problem. Bruce Hammock writes, "Fatty acid composition in the Western diet has shifted from saturated to polyunsaturated fatty acids (PUFAs), and specifically to linoleic acid (LA, 18:2), which has gradually increased in the diet over the past 50 y to become the most abundant dietary fatty acid in human adipose tissue." https://pmc.ncbi.nlm.nih.gov/articles/PMC9060469/

Vijay p. Singh says, "Separately, on analyzing global COVID-19 mortality data and comparing it with 12 risk factors for mortality, they found unsaturated fat intake to be associated with increased mortality. This was based on the dietary fat patterns of 61 countries in the United Nations' Food and Agricultural Organization database. Surprisingly, they found saturated fats to be protective."https://www.medpagetoday.com/reading-room/aga/lower-gi/86940

It's interesting that fasting and exercise furnish some protection from excessive polyunsaturated fatty acid intake. For example, "The increased proportional intake of dietary fat, decrease in feeding frequency and increased physical activity in free-ranging compared to captive cheetahs are all predicted to result in enhanced mitochondrial FA oxidation through the lowering of circulating glucose concentrations and insulin:glucagon ratios. During fasting/refeeding cycles and increased levels of exercise, tissue PUFA concentrations have been shown to deplete rapidly in both humans and rats. These studies show that most PUFAs, including α-linolenic acid (ALA) and linoleic acid (LA), are preferentially oxidized in periods of exercise or fasting. During refeeding, SFAs and monounsaturated fatty acids (MUFAs), such as palmitic acid and oleic acid, are also more rapidly replaced than any of the PUFAs. Similarly, the concentrations of most plasma PUFAs and MUFAs have been shown to be significantly lower in rats fed a high fat ketogenic diet than in controls. The predicted increase in FA oxidation in free-ranging cheetahs is therefore likely to also skew their serum FA profiles toward lower proportional serum concentrations of PUFAs and MUFAs relative to SFA." https://pmc.ncbi.nlm.nih.gov/articles/PMC5167222/

In the final analysis, dietary saturated fats are benign, if not outright beneficial over a wide range of intakes as long as they are consumed in the context of healthy nutrient configuration as in whole foods. https://pmc.ncbi.nlm.nih.gov/articles/PMC7846167/
I really wish OXO would put out a statement here.

A lot of people use it's black plastic tools like this one [1] -- like a lot of brands, OXO calls its black plastic tools "nylon" to differentiate from "silicone" -- and it would be really, really good to know if OXO has always rigorously made sure never to use recycled plastics, or if testing shows that its own products contain flame retardants.

In other words, when you pay premium prices for stuff like OXO as opposed to a dollar-store black plastic spatula, are you getting premium quality that avoids the kind of contamination described in the article? Or are the premium prices just going to the design and marketing, but not to the manufacturing?

I was evaluating it for a month and caught myself regularly switching to an IDE with non-AI intellisense because I wanted code that actually works.
Wow. That is sad, and reflective of the world you live in and people you associate with I guess.

But healthiness can be measured pretty objectively through health outcomes, and high BMI and low exercise are both independently highly correlated with bad ones across the whole spectrum of health aspects. It's not just common sense, it's mountains of evidence over decades across every aspect of medicine.

The fact that some (in your community, many) people twist this around and make it about something else entirely is sad, but in no way affects the objective truths:

- it is objectively healthier to be active than inactive, regardless of obesity

- it is objectively healthier to have average weight than obese, regardless of activity level

I've lived in a few different places and found the culture around exercise and diet to be very different in different places, so I'm not surprised experiences can vary so much. I am curious where you see this bizarre culture of shaming people for exercising.

There is a reality distortion field in existence now because almost every police interaction is recorded (body cams are everywhere nowadays) and the ones that go bad are put on full blast across social media and the news, despite them being somewhere on the order of 1 in 1,000,000 encounters.

Seriously, if car accidents were reported like police accidents, we probably would have been forced by confused ideologues to ban automobiles 2 years ago.
At the end of the day an LLM is just a compiler anyway. The developer isn't going away even if 100% of the code is generated by LLMs, just as the developer didn't go away when we stopped spending our days flipping toggle switches.
Stainless, when used properly, won't have hard-stuck burnt oil on it. They clean up nicely by just boiling some water in it and then a light scrub-- no need for dishwasher.

Worst case-- you've gone too high in temperature for too long and you need some bon-ami.
In a strange way, yes, with the premise that the world is otherwise the realm of uncreative, uninspired people. But the comment was addressed more at the odd lifelessness of the imagery.
Right, and my argument is that the double standard itself is not just. I do know as a matter of practicality that I don't really have a legal leg to stand on here; the law is what judges say it is, and they've said it is the way it currently is.

I do not find "the justice system treats them differently, therefore they are different and the justice system is just in treating them differently" to be a compelling argument that the double standard is just. It's just a circular appeal to authority; any behavior by the justice system is morally permissible under that idea, simply because the justice system declares it to be so.

My question is how is it just that differing standards apply? And furthermore, how is it just that that leniency is granted to the benefactor of a severe power imbalance? Unconstitutional search and seizure could absolutely be a crime; in this situation, a citizen would likely be charged under the CFAA, which is a crime.
Are you sure this is the same thing? The word ‘petroleum’ is not in the paper you link.

Naively, I would think the paper you linked is about carbon (the charcoaley substance) derived from vegetables being used as a black food coloring, and the poster above is talking about “carbon black oil”, a type of oil derivative that looks black - two completely different things.

Doing a startup is a very high-risk activity, and multiple income streams help to reduce the risk.

You only need one success to be a billionaire (if that's your goal), but the odds of whatever your startup is being that one success are very low. Almost all successful entrepreneurs became successful by trying out a lot of things that didn't work before they discovered one that did.
Is that true even for mp3 though? Apparently it actually has a universal browser support up to MSIE 9 (!), while Ogg Vorbis and FLAC are now supported by all modern browsers after MSIE [1]. Opus seems to be the earliest format with less support than that, while this library only dates back to 2020.

It's a bit unfair to compare automation in construction with other industries where you're in a controlled environment (factory). It's a much more difficult problem and therefore would require a much greater investment in technological development, to what end? Put a large percentage of people out of work? Would it really reduce housing prices, or just increase profits?
It’s all Greek to them.
It wasn't illegal (unconstitutional) at the time they did it, which is different from not knowing. They would have had to see the future to know.

Also keep in mind "illegal" and "unconstitutional" are different levels - "illegal" deals with specific laws, "unconstitutional" deals with violating a person's rights. Laws can be declared unconstitutional and repealed.
