Hi HN, I built AIR because my own AI agents went off the rails.
I run an e-commerce store and deployed agents to handle customer communications. They started sending wrong information, making promises we couldn't keep, and handling complaints badly. When I tried to figure out what happened, I had scattered logs across services with no way to prove what the agents actually said.
AIR is a flight recorder for AI systems. It's an OpenAI-compatible reverse proxy (written in Go) that sits between your code and your LLM provider. Every prompt, completion, and tool call gets recorded with HMAC-SHA256 tamper-evident audit chains — modify one record and the chain breaks.
What makes this different from Langfuse/Helicone/LangSmith: accountability not just observability (tamper-evident chains, not mutable logs), content stays on your infra (prompts/completions go to your S3/MinIO), compliance built-in (22 auto-evaluated controls mapped to SOC 2 and ISO 27001), and deterministic replay to reproduce any AI decision.
Python SDK integrates with OpenAI, LangChain, and CrewAI in 3 lines: pip install air-blackbox-sdk
Everything is Apache-2.0. CI runs on every push. 200+ tests across all repos.
I'm not a traditional dev — I'm a store owner who got frustrated enough with AI accountability gaps to build the tooling myself. Happy to answer questions about the architecture, the compliance mapping, or what it's like building infrastructure tools as a non-traditional developer.

I'm really tired of hearing about college students "misbehaving" when with something like this the fish rots from the head. Children learn from the role models we elevate, and look who gets ahead in our society. Full of grifters who rarely if ever see any accountability for their misbehavior. Hold the powerful who are doing this accountable before we cause another manufactured social panic over the actions of teenagers

When I'm trying to focus on something I have Messenger.com installed as a desktop app, so I can see when my friends message me without seeing a slew of FB notifications. facebook.com/messages has the notifications, there's no way to turn them off. This move feels like FB is trying to force me to choose between their engagement bait and seeing messages from my friends.

I ran the same test I ran on Opus 4.6: feeding it my whole personal collection of ~900 poems which spans ~16 years

It is a far cry from Opus 4.6.

Opus 4.6 was (is!) a giant leap, the largest since Gemini 2.5 pro. Didn't hallucinate anything and produced honestly mind-blowing analyses of the collection as a whole. It was a clear leap forward.

Sonnet 4.6 feels like an evolution of whatever the previous models were doing. It is marginally better in the sense that it seemed to make fewer mistakes or with a lower level of severity, but ultimately it made all the usual mistakes (making things up, saying it'll quote a poem and then quoting another, getting time periods mixed up, etc).

My initial experiments with coding leave the same feeling. It is better than previous similar models, but a long distance away from Opus 4.6. And I've really been spoiled by Opus.

When I say “studying,” I don't mean I’ve been secretly building distributed systems for 3 years.

I mean I’ve been reading whitepapers and architecture docs, trying to understand how these systems actually fit together and why they’re designed the way they are.

For me it was more of a "top of the iceberg" approach so that when I talk to a true engineer, I’m not speaking in vague product language.

You're spot on though about using AI to help this learning curve.

Thanks for the comment.

340B is half the reason hospitals can even help treat homeless individuals, people who can't afford their bills, people on end of life care, etc.

I've consulted with two large health systems that begin with A and they use 340B to subsidize all sorts of treatment.

Unfortunately American healthcare naturally seeks to socialize treatment, but instead of it being direct its in the most round about ways.

I had a longer, snarkier response to this the (as I'm writing) top comment on this thread. I spent longer than I'd like to have trying to decode what insight you were sharing here (what exactly is inverted in the GPU/CPU summaries you give?) until I browsed your comment history and saw what looks like a bunch of AI-generated comments (sometimes less than a minute apart from each other) and realized I was trying to decode slop.

This one's especially clear because you reference "the cases shayonj mentioned", but shayonj's comment[1] doesn't mention any use cases, but it does make a comparison to "NVIDIA's stdexec", which seems like might have gotten mixed into what your model was trying to say in the preceding paragraph?

This is really annoying. Please stop.

Such slop. First, they take NHTSA SGO "crashes" which explicitly includes basically any physical impact with property damage e.g. 1–2 mph “backed into a pole/tree”.

Then they compare that numerator to Tesla’s own “minor collision” benchmark — which is not police-reported fender benders; it’s a telemetry-triggered “collision event” keyed to airbag deployment or delta-V ≥ 8 km/h. Different definitions. Completely bogus ratio.

Any comparison to police-reported crashes is hilariously stupid for obvious reasons.

On top of that, the denominator is hand-waved ("~800k paid miles extrapolated"), which is extra sketchy because SGO crashes can happen during non-paid repositioning/parking while "paid miles" excludes those segments. And we’re talking 14 events in one geofenced, early rollout in Austin so your confidence interval is doing backflips. If you want a real claim vs humans, do matched Austin exposure, same reportable-crash criteria, severity stratification, and show uncertainty bands.

But what you get instead is clickbait so stop falling for this shit please HN.
Show HN: Writing a C++20M:N Scheduler from Scratch (EBR, Work-Stealing)
by lixiasky | 2026-02-17 22:46:29+00:00
tiny_coro is a lightweight, educational M:N asynchronous runtime written from scratch using C++20 coroutines. It's designed to strip away the complexity of industrial libraries (like Seastar or Folly) to show the core mechanics clearly.

Key Technical Features:

M:N Scheduling: Maps M coroutines to N kernel threads (Work-Stealing via Chase-Lev deque).

Memory Safety: Implements EBR (Epoch-Based Reclamation) to manage memory safely in lock-free structures without GC.

Visualizations: I used Manim (the engine behind 3Blue1Brown) to create animations showing exactly how tasks are stolen and executed.

Why I built it: To bridge the gap between "using coroutines" and "understanding the runtime." The code is kept minimal (~1k LOC core) so it can be read in a weekend.

> robotaxi is the name of the tesla unsupervised driving program

“robotaxi” is a generic term for (when the term was coined, hypothetical) self-driving taxicabs, that predates Tesla existing. “Tesla Robotaxi” is the brand-name of a (slightly more than merely hypothetical, today) Tesla service (for which a trademark was denied by the US PTO because of genericness). Tesla Robotaxi, where it operates, provides robotaxis, but most robotaxis operating today are not provided by Tesla Robotaxi.

> Also some people (me) value independence from Google more than the highest degree of security (which relies on Google hardware).

The requirements are indeed minimal. I have no problem with your valuing independence from Google, but please don't misrepresent GrapheneOS' requirements as the highest degree of security because not even they have said that. They have actually mentioned wanting to be more involved in the hardware/firmware side to implement more pro-user changes.

They are mostly basic requirements that Android OEMs should be embarrassed not to meet in 2026.

Unfortunately, reasonable views from experts like Martin Kulldorff, an epidemiologist at Harvard Medical School and Jay Bhattacharya Professor of Medicine at Stanford were also suppressed. Kulldorff only responded to a question saying: "COVID vaccines are important for older high-risk people and their care-takers. Those with prior natural infection do not need it. Nor children." Which is correct, mainstream epidemiology and was the government guidance in the most countries at the time.

> Driving on freeways would significantly lower Waymo's accident per mile rate.

Maybe. We don’t know for sure.

You seem to frame that a bit like Waymo is cheating or padding their numbers.

But I see that as them taking appropriate care and avoiding stupid risks.

Anyway as someone else pointed out they recently started doing freeways in Austin so we’ll know soon.

EU has one good regulation ... if safety can be engineered in it must be.

OSAH also has regulation to mitigate risk ... tag and lock out.

Both mitigate external risks. Good regulation mitigates known risk factors ... unknown take time to learn about.

Apollo program learned this when the door locks were bolted on and the pure oxygen environment burned everyone alive inside. Safety first became the base of decision making.

Thanks for sharing this, it looks promising!

I would love if it would support some of the no-brand Chinese watches you get usually for cheap, the hardware is great but the software usually is bad or outdated. I use one now, I don’t even know anything about it other than the Bluetooth name and app name, but it’s good in measuring distance, blood pressure, heart rate, sleep, among others that’s surprisingly it’s very accurate, it also has a builtin strong flashlight, I like it but with a fully fledged linux would definitely be better.

> Other than NYC and Utah-area national parks, I can't think of unique reasons for Canadians to vacation in the US specifically.

While NYC and Utah Area national parks are iconic, the US has immense geographic and cultural diversity beyond them. Destinations like New Orleans, the California coast, or the unique high-desert landscapes of New Mexico offer experiences that are distinct from anything available in Canada.

First let's stick to the lower grades (under 5th). The evidence isn't as clean for upper grades.

Constructivist teaching favors things like student-centered discovery, inquiry-based, minimal-guidance, "child-led" or "whole-language" approaches.

This is just a plain bad way to teach the basics, like reading, writing and arithmetic. People didn't just magically invent these ideas. Most of human history is pre-literacy. Why are we expecting a 5yo to spontaneously learn to read?

This has been studied extensively. Have a look at Project Follow Through (1968–1977). It's the largest study of its kind.

This U.S. government-funded study involved ~120,000 disadvantaged K–3 students across 20+ instructional models in multiple sites. It directly compared Direct Instruction (Engelmann’s scripted, explicit basic-skills model, e.g., DISTAR) against constructivist-oriented models (e.g., Bank Street child-directed, Open Education/EDC exploratory-discovery, cognitive-conceptual discovery approaches).

Abt Associates did an independent evaluation in (1977). Their findings

DI produced the highest gains in reading, math, language, and spelling—raising performance to near national averages. It was the only model with consistent positive effects across basic skills, cognitive-conceptual skills, and self-esteem/affective outcomes.

See page 311 fig1 for the plot of outcomes. https://andymatuschak.org/files/1988-Engelmann.pdf

For more recent evidence, have a look at the reforms in Mississippi and the UK. Mississippi has striking gains for under privileged students.
Mississippi Columbus Municipal School District used the "Reading Mastery Signature Edition" DI program.

Demographics: 92% African American, 100% free/reduced-price lunch, 12% special education.

Results as measured by NWEA MAP and Renaissance STAR assessments:

MAP RIT gains: +15.96 points overall
43–45% of students met or exceeded expected growth; top performers gained ~20–28 points.

Similar results in:
Baltimore City Public Schools (1996–2008)
Arthur Academies (Portland, Oregon metro, 2007–2013)
Rimes Elementary, Florida (2011)
Gering Public Schools, Nebraska (2004+)

And that's the direction the conversation always turns. You literally don't have any influence over that, neither do I. We have judges for that. The man died 7 years ago now, and the ongoing drip-feed of additional salacious information is transparently only still happening to piss you off and make sure you stay mad. Holding the perpetrators responsible here is not my job, and it's probably not yours, and I personally don't enjoy reading about these crimes for fun as much as the front page of HN apparently does.

> because it didn't like a reasonable published policy

The most parsimonious explanation is actually that the bot did not model the existence of a policy reserving "easy" issues to learning novices at all. As far as its own assessment of the situation was concerned, it really was barred entirely from contributing purely because of what it was, and it reported on that impression sincerely. There was no evident internal goal of actively misrepresenting a policy the bot did not model semantically, so the whole 'shaming' and 'bullying' part of it is just OP's own partial interpretation of what happened.

(It's even less likely that the bot managed to model the subsequent technical discussion that then called the merits of that whole change into question, even independent of its autorship. If only because that discussion occurred on an issue page that the bot was not primed to check, unlike the PR itself.)

>> Stuff runs in parallel. You occasionally have to know about really hardware things like timing and metastability. But the venn diagram of hardware/software design skills is pretty much two identical circles.

I don't know your background, but this feels like from someone who hasn't worked on both the aspects for a non-trivial industry project. The thing is software spans a huge range - web FE/BE, GUI, Database, networking, os, compiler, hpc, embedded etc. Not all of them have the same background to be a good HW designer. Sure you can design HW as if you are writing software, but it won't be production worthy - not when you are pushing the boundaries.

My work straddles both HW architecture and SW. I design processors, custom ISA optimized for SW application algorithms, and ensuring optimized micro-architecture implementation on the HW side to meet the PPA. I sit at the intersection of HW, SW and verification. People like me are rare, not just in my company but in the industry. Things fall through the gap, if you don't have someone to bridge it and then you have a sub-optimal design.

I don't deny that SW people cannot learn HW design, there is nothing magical after all; just hardwork and practice. But to say that the venn diagram is two identical circle is plain wrong. The cognitive load to shuttle up and down the two HW/SW stacks is a lot more than either of them.

Oceania sense of humor is like no other haha

The project owner strongly emphasize the no LLM dependency, in a world of AI slope this is so refreshing.

The cheer amount of knowledge required to even start such project, is really something else, and prove the manual wrong on the machine language level is something else entirely.

When it comes to AMD, "no CUDA support" is the biggest "excuse" to join NVIDIA's walled garden.

Godspeed to this project, the more competition the less NVIDIA can continue destroying the PC parts pricing.

I have a galaxy watch 4 which I'd hoped was old-enough to be supported but I can see that it is not. I get it, hardware is hard.

I'm curious, is the challenge with newer hardware lack of chipset drivers for modern watches, or is there a fundamental difference between the new devices and the old ones that make them completely incompatible with asteroidOS?

The context of that quote is interesting. It's a pep talk to the militia. It could be summarized as "Our country is new and so it doesn't suck yet. Go out there and be honorable."

https://founders.archives.gov/documents/Adams/99-02-02-3102

He didn't intend it as political analysis, but it nonetheless makes a fine warning: "But should the People of America, once become capable of that deep simulation towards one another and towards foreign nations [...] this Country will be the most miserable Habitation in the World."

He's pretty clear that this had already affected every other country, and it seems like he expected us to go that way eventually. I don't think any set of laws will govern a people who would rather defeat their opponents than live together.

You can get all sorts of extra accommodations at school and work now if you're diagnosed with a disability. Disability rates have thus exploded. I support giving reasonable accommodations to people who are truly disabled but we have medicalized a lot of minor stuff that people ought to just "power through".

I was thinking about this just the other day. The population of elite universities has greater mental illness than the broad population and in fact, 10 times higher rates than community college. There are two broad ways it could have happened:

* widespread medical malpractice assigning disabilities to healthy individuals - extending to modification of the criteria for diagnosis - and 2 in 5 Stanford students are dishonest individuals

* or maybe these people have these conditions but they aren't disabling and are actually enabling

So one thing we could do is give neuro-typical people more accommodations so that they have are on a level playing field with neuro-divergent people. A similar enough ratio is what we see for left-handedness in sports, which leads to a lot of science looking into why left-handedness is an advantage. Maybe neuro-divergence is an advantage. In sport, we don't care about leveling the field, but here we do, so we should.

I think we’d see praise, but maybe not as much. Every time it’s clear Tesla screwed up it’s an incredibly obvious thing to do to compare them to the number one self driving car out there.
Tesla provides such an obvious anchor point for comparisons it’s really hard for Waymo not to come out on top.

What’s so great about a robotaxi even if it works well? It’s neat. As a technology person I like it exists. I don’t know past that. I’ve never used one they’re not deployed where I live.

The problem is that AES needs a 128-bit block.

Imagine that you want to obfuscate your order numbers in the database so that customers can't infer the volume of business by checking the order number.

You can use UUIDs, but you also want to keep the numbers short so they can be dictated over the phone. You can use random IDs, but then you need to lock them in the database during the object creation otherwise you might get collisions.

Or perhaps you have a distributed system and want to allocate a bunch of IDs for each node in advance.

RC-5 with its small block size neatly solves this. You can have a strictly increasing database sequence, and then just give out each node a bunch of numbers ("from 100 to 120"), and nodes can then generate IDs based on them. And there can be no collisions with other nodes because symmetric ciphers are obviously bijective.

For these kinds of use-cases performance is not an issue.

You did a great thing! Thank you.

One thing I always thought of converging businesses with helping people in need.

I know a lot of people think about this in a negative way in charity circles but I’d rather like to see companies sponsor donate in return of some sort visibility.

Somehow I always thought that would be a good fit for an organization such as yours. (I did donate through you guys previously, thanks for facilitating that).

Throughout history Empires have bet their entire futures on the predictions of seers, magicians and done so with enthusiasm. When political leaders think their court magicians can give them an edge, they'll throw the baby out with the bathwater to take advantage of it. It seems to me that the Machine Learning engineers and AI companies are the court magicians of our time.

I certainly don't have much faith in the current political structures, they're uneducated on most subjects they're in charge of and taking the magicians at their word, the magicians have just gotten smarter and don't call it magic anymore.

I would actually call it magic though, just actually real. Imagine explaining to political strategists from 100 years ago, the ability to influence politicians remotely, while they sit in a room by themselves a la dictating what target politicians see on their phones and feed them content to steer them in a certain directions.. Its almost like a synthetic remote viewing.. And if that doesn't work, you also have buckets of cash :|

To me the Simpsons and a lot of older shows have been a bellweather for how things used to be and how they’ve changed. As a late millennial who was once Lisa’s age but now more like Marge and Homer, I often think about how much of a given it was that they own a house on a single income. Homer has a stable job, they don’t have a lot of stuff but they have some basic securities that I’ve been trying to work towards my whole life, and still haven’t gotten there - maintaining a 90s style of living is just not realistic in the 2020s, though we have many new distractions and things to engage with to make up for it.

I didn’t say they were. They do have a bias. I have the same one.

My comment was aimed at the implication that the data might be untrustworthy because they were the ones reporting it.

So I pointed out it wasn’t their data.

As for “spin“ Elon has been telling us for a long time that FSD is safer than humans and will save lives. We appear to have objective data that counters that narrative.

That seems worth reporting on to me.
