I am personally going to avoid anonymous social media as much as I can going forward. (Not counting topic-specific forums and such). They have all become toxic cesspools and now AI is making it all so much worse.

I’ve stopped using Facebook a long time ago, but started using a similar locally made social media app/site, which is based on logins tied indirectly to national ID. Holy crap it’s so much better. Only real people. No bots or scams. Even the ads are better. Actual relevant local businesses. And people hesitate before writing nasty comments. Not that I’m using it a lot, I’m still not a big social media guy, but having groups for the neighbourhood or town is nice for becoming aware of events and such happening nearby.

I still have the Facebook account for now. There’s a group or two I need to check in on sometimes. Every time I log in I get so confused why anyone would still use it.

Congress should pass the RPM act and exempt race cars from the clean air act. I never said you can't cherry pick individual problems with environmental regulation.

I just don't like the general attitude that because you can find something to disagree with that environmental regulation as a general rule is bad. It isn't.

There are thousands and thousands of pages of environmental regulations. Obviously people are going to be able to find some things that need to be revisited, but don't throw the baby out with the bath water. Nothing should be repealed without evidence and in many cases amendments are more prudent than repeals.

I think EVERYONE is worthy of privacy. The ad cartel has millions (billions?) of lobby money in their war chest. Any real reform would be moving a mountain. Funny how it's framed this way; shows just how impossible it is to concede to privacy for all. Instead we have as another commenter said: "a two-tier surveillance state."

POP3 is more for reading and acting on your email in one place (taking notes, plan actions, discard and delete,…). No need to consume them on other devices as you’ve already extracted the important bits.

I use imap on my mobile device, but that’s mostly for recent emails until I get to my computer. Then it’s downloaded and deleted from the server.

Implementation Notes:

- There is no reason you have to expose the skills through the file system. Just as easy to add tool-call to load a skill. Just put a skill ID in the instruction metadata. Or have a `discover_skills` tool if you want to keep skills out of the instructions all together.

- Another variation is to put a "skills selector" inference in front of your agent invocation. This inference would receive the current inquiry/transcript + the skills metadata and return a list of potentially relevant skills. Same concept as a tool selection, this can save context bandwidth when there are a large number of skills

By the time that happens, Opus 5 and GPT-5.5 will be out. At that point will a GPT-5.2 tier open-weights model feel "good enough"? Based on my experience with frontier models, once you get a taste of the latest and greatest it's very hard to go back to a less capable model, even if that less capable model would have been SOTA 9 months ago.

Anthropic added features like this into 4.5 release:

https://claude.com/blog/context-management

> Context editing automatically clears stale tool calls and results from within the context window when approaching token limits.

> The memory tool enables Claude to store and consult information outside the context window through a file-based system.

But it looks like nobody has it as a part of an inference loop yet: I guess it's hard to train (i.e. you need a training set which is a good match for what people use context in practice) and make inference more complicated. I guess more high-level context management is just easier to implement - and it's one of things which "GPT wrapper" companies can do, so why bother?

> btw don't try that with something that is on their list like ammo, even one bullet. Your life will be ruined.

I've done that too. You travel so aggressively, eventually you have some oopsies.

I went through a stint where I was driving for work, and working with a bunch of people in a woodsy state. A guy would take us shooting, and he asked me to buy a box of ammo to replace what I shot - so 20 bucks for 500 rounds of .22 caliber ammo.

Next time I flew was the first time I had actually been selected for TSA precheck - you know, the Trusted Traveler program and you can guess what I left in my carry-on. I was very apologetic and had to talk to a very grumpy city police officer, but it was fine. I paid a fine of $130, and that was it - they offered to let me check my bag to keep the munitions too!

It has never even come up with my 3 Global Entry interviews either. And yes - I live in a blue state.

Obviously don't do it. It wasn't a problem for me, but very much YMMV. I know someone else who got dinged for having a banana they bought in a foreign airport, and that continues to come up in their Global Entry interviews. Live ammunition < Bananas, apparently.

Collective decisions are unavoidably political, and grid electricity has to be a collective decision! My hope is that we can take the partisan aspect out of the politics, however, and reduce it to a discussion of the tradeoff of values: cost, reliability, climate, and any other values that we need to include. Fortunately I think that for nearly any value set, the answer is very similar.

Hey all,

I'm the creator of the PII Firewall Edge API (currently on RapidAPI).

I saw a lot of devs struggling to implement safety guardrails correctly—most were just using basic regex or heavy LLMs that hallucinate.

So, I decided to package my API into a full-featured UI/Toolkit called Risk Mirror.

What it does: It sits between your users and your LLM (OpenAI/Anthropic) and strips out sensitive data before it leaves your server.

The Tech (Zero AI Inference): Instead of asking an LLM "is this safe?", I use:

152 PII Types: My custom engine covers everything from US Social Security Numbers to Indian Aadhaar cards and HIPAA identifiers.
Shannon Entropy: To detect high-entropy strings (API keys, passwords) that regex misses.
Deterministic Rules: 100% consistency. No "maybe."
Why use this?

It's Tested: The underlying API engine is already battle-tested.
It's Fast: <10ms latency.

Includes a 'Twin Dataset' generator for Data Scientists (redact CSVs securely). Feedback welcome!"

You seem to be on a streak of making rant posts about Ai on HN

https://news.ycombinator.com/submitted?id=cadabrabra

Your opinion is in the minority here now because many of us have overwhelmingly positive experience with agents

Moltbook is not the proof you are looking for. I agree it's dumb af, but it's a novelty in a hype cycle. We won't be talking about it in a few months

You won't find proof because there is not enough research and the field is evolving faster than the research on outcomes paper pipeline can process.

I really dislike this whole debate because I never wanted to be lumped in with 3D gun printing weirdos.

When I first told my very non-technical somewhat new friend about my 3D printer, they looked really concerned and told me they weren’t comfortable with it because of how people make weapons with them.

I’ve had to spend a lot of time building trust and showing that I’m not one of those weirdos.

Ultimately I don’t think any kind of printed gun banning law has a tangible impact (it’s not like guns with serial numbers aren’t regularly getting away with murder), but what I don’t like is that the law and discussion around it validates this stupidity and continues to lump me in with gun weirdos.

It’s weird to own a gun. It’s weird to print a gun. I don’t even think the 2nd amendment is very necessary and is clearly not capable of stopping tyranny (and the amendment itself says that’s not its purpose anyway).

At this point we could probably get a coalition of Trump cult members who have no consistent ideology (Trump doesn’t like guns) and “liberal pansies” to just repeal the 2nd amendment and become a normal country.

I cannot speak for the US but in Germany there is certainly some amount of violence towards local politicians but also other parts of administration (job centers, etc)
Traditionally there was maximum transparency (names of every single reponsible person for each minor municipal job) with little choice for employees to opt out. This is changing not under special rules but mostly under GDPR adoption. However, particularly elected officials (even for very minor local roles) even have to expose their street address to get elected (such legal requirements can provide GDPR exception). This generates real risk. If less and less or the "wrong" people go into administration we are in trouble, IMHO. I know there is a lot of governments vs the people sentiment popping up. But we need to just make sure that we treat our administration also as people in certain situations. (Disclaimer: as a university lecturer I am officially a public servant, but I do not think any of this would apply to me: I hardly have to fear the wrath of the students)

Kernel 4.18 is _ancient_, weird to test on that. Also I wonder if the whole performance increase can't just be achieved by lowering the readahead size a bit. I see in their notes they have a decent SSD but set the blockdev readahead to 64. Depending on your workload it's much more performant to lower that to 16. As mentioned in TFA, fast storage is the most important factor here, and in my experience combining that with a smaller readahead pretty much fixes any read amplification issues you get with the larger readahead.

Is this a real question? Legally buying guns in the US come with registration of serial numbers, names, and addresses. Printing a gun does not. Printing a gun also does not need to wait for a multi-day delay from a background check. Depending on the printer, it could just take multiple days to print.

Asking why someone would want to do this is just not trying very hard in the conversation is actually pretty myopic.

> Those are descriptions of my thoughts. So no, not anthropomorphisation

The result of anthromorphisation. When we treat a machine as a machine, we less need to understand it by seems and feel.

> They use the term "thinking" all the time.

I find not. E.g. ChatGPT:

Short answer? Not like you do.

Longer, honest version: I don’t think in the human sense—no consciousness, no inner voice, no feelings, no awareness. I don’t wake up with ideas or sit there wondering about stuff. What I do have is the ability to recognize patterns in language and use them to generate responses that look like thinking.

3D printed guns haven't been zip guns in a long time. That reads as willful ignorance. Only the receiver or frame are controlled. Every other part can be purchased online without any checks. Hoffman Tactical's Orca and a myriad of pistol frame can be used to produce weapons on par with commercial weapons. Many commercial pistols are polymer frames. A good 3d printed pistol frame is no different than a cast nylon polymer frame.

If you want to see what is possible with 3d printed guns now I recommend Hoffman Tactical and PSR on YouTube.

Maybe I'm not the target market for this, but how hard is it REALLY to manage a RDBMS?

Any Linux distro can have MySQL or Postgres installed in less than five minutes and works out of the box

Even a single core VPS can handle lots of queries per second (assuming the tables are indexed properly and the queries aren't trash)

There are mature open source backup solutions which don't require DB downtime (also available in most package managers)

It's trivial to tune a DB using .conf files (there are even scripts that autotune for you!!!)

Your VPS provider will allow you to configure encryption at rest, firewall rules, and whole disk snapshots as well

And neither MySQL or Postgres ever seem to go down, they're super reliable and stable

Plus you have very stable costs each month

It is not weird in the slightest. These things are coordinated at the state level all the time.

This is probably one of those good tests of "is your 'conspiracy theory' meter properly calibrated", because if it's going off right now and you are in disbelief, you've got it calibrated incorrectly. This is so completely routine that there's an entire branch of law codified in this way called the "Uniform Commercial Code": https://en.wikipedia.org/wiki/Uniform_Commercial_Code and see the organization running this' home page at https://www.uniformlaws.org/acts/ucc .

And that's just a particular set of laws with an organization dedicated to harmonizing all the various states laws for their particular use cases. It's not the one and only gateway to such laws, it's just an example of a cross-state law coordination so established that it has an entire organization dedicated to it. Plenty of other stuff is coordinated at the state level across multiple states all the time.

The TypeScript + MongoDB combination for AI coding is a smart architectural choice. I've found that schema-less databases reduce the class of errors agents struggle with most - the migration/schema drift issues that require understanding of state over time.

Question: How are you handling the built-in auth when users want to extend it? For example, adding OAuth providers that aren't pre-configured, or custom claims/roles logic. Is this something the framework supports as extension points, or would users need to fork/modify core auth code?

The Claude Agent SDK integration is interesting - have you found specific prompting patterns that work better for TypeScript generation vs other languages? Curious if the type system actually helps agents self-correct as expected.

Not a great example as that "done" tool (whose currrent iteration barely functions) will be made unavailable after a few years.

That tool is still very much in active use in my industry, and we'll need to figure out what to do with some 10000 fla files that we need to occasionally edit and republish (hint: the solution probably involves a certain Swedish software repository).
by Soerensen | 2026-02-03 16:40:16+00:00
The agent orchestration point from vessenes is interesting - using faster, smaller models for routine tasks while reserving frontier models for complex reasoning.

In practice, I've found the economics work like this:

1. Code generation (boilerplate, tests, migrations) - smaller models are fine, and latency matters more than peak capability
2. Architecture decisions, debugging subtle issues - worth the cost of frontier models
3. Refactoring existing code - the model needs to "understand" before changing, so context and reasoning matter more

The 3B active parameters claim is the key unlock here. If this actually runs well on consumer hardware with reasonable context windows, it becomes the obvious choice for category 1 tasks. The question is whether the SWE-Bench numbers hold up for real-world "agent turn" scenarios where you're doing hundreds of small operations.

It’s a sticky issue. Without QI, it seems very plausible that many law enforcement departments would be seriously hamstrung by continual waves of legal action and thus cost taxpayers a lot more to operate effectively. Not only would many people use a court of law as a fallback from the court of public opinion, but the legal industry would support this given the lucrative monetary and reputational advantages of suing the government.

And I’m saying that as someone extremely pro-curtailment of police/TSA/CBP scope and resources, and extremely critical and aware of the law enforcement abuse and overreach epidemic. This one just doesn’t have an easy solve—not without a massive overhaul of the entire US justice system down to the roots.

What PII-Shield does:
It's a K8s sidecar (or CLI tool) that pipes application logs, detects secrets using Shannon entropy (catching unknown keys like "sk-live-..." without predefined patterns), and redacts them deterministically using HMAC.

Why deterministic? So that "pass123" always hashes to the same "[HIDDEN:a1b2c]", allowing QA/Devs to correlate errors without seeing the raw data.

Key features:
1. JSON Integrity: It parses JSON, sanitizes values, and rebuilds it. It guarantees valid JSON output for your SIEM (ELK/Datadog).
2. Entropy Detection: Uses context-aware entropy analysis to catch high-randomness strings.
3. Fail-Open: Designed as a transparent pipe wrapper to preserve app uptime.

The project is open-source (Apache 2.0).

Repo: https://github.com/aragossa/pii-shield
Docs: https://pii-shield.gitbook.io/docs/

I'd love your feedback on the entropy/threshold logic!
by mavdol04 | 2026-02-03 16:41:04+00:00
Thanks! Got it, I will add more examples for that. Currently you can do both: run dynamically untrusted code with eval, or run fully encapsulated logic (like in the existing examples).

I made a small example that might give you a better idea (it's not eval, but shows how to isolate a specific data processing task): https://github.com/mavdol/capsule/tree/main/examples/javascr...

And yes, you are spot on regarding LeetCode/gaming platforms. The resource limits are also designed for that kind of usage.

I mean, it'd be good if these tools followed the xdg base spec and put their config in `~/.config/claude` e.t.c instead of `~/.claude`.

It's one of my biggest pet peeves with a lot of these tools (now admittedly a lot of them have a config env var to override, but it'd be nice if they just did the right thing automatically).

To get it through security somewhere with metal detectors. That's probably the only reason to specifically fear a 3D-printed gun in a nation full of proper guns.

Of course, 3D printed plastic ammo isn't likely to be very effective.

(Maybe they're worried that before long, 3D printing with metal will almost as easy and affordable as plastic 3D printing is now, and people will be printing off entire arsenals of very effective firearms?)

Really cool deck! Anyone out there play Mu? It's an _excellent_ trick taking card game. One of the few (complex, trick-taking... I'm not counting stuff like Uno in this genre) card games that I know of that works really well with 5 or 6 players.
This deck _almost_ would work for Mu, but it'd need different point values. (I keep having to rebuy new Mu games when the deck wears out so I've been contemplating other possibilities.)

I do not like these "compromise" suggestions. This is just an invitation for later expansion.

In general I think a lot of people, including and especially a lot of people who consider themselves "informed" on such matters, do not really understand the nature of the government's relationship to power.

Politicians portray themselves as far weaker and more helpless than they actually are. An example--I hear people complaining about "lobbying" by "big money interests" all the time. It is portrayed that a handful of billionaires are running the world, and while some of that influence does of course happen, the reality is no where near as clean and cut and dry as it is portrayed. The power companies have has far more to do with real world things like employing X number of people or providing critical services to a region than having $X in the bank. A lot of what gets called "lobbying" I think could more accurately be portrayed as "extortion". This is just one example. I've had a handful of situations where I got a peak behind the curtain into these dealings and the reality was nothing like the public perceptions. The politicians forced the CEOs of huge energy companies to "play the villain" in the run up to an election, meanwhile they pretended to be fighting them. The reality was that the situation that they were fighting over had inevitable but unpopular constraints that did not have a solution people would be happy with. The companies were forced to keep their mouths shut while the politicians and newspapers attacked them, as if they were not holding all the cards and had the ability to do what they claimed they were trying to do at any moment. These companies were quietly repaid for their compliance after the election with some unnoticed unrelated regulatory changes, but they truly had little say in the matter, the politicians were 100% in the driver's seat.

These politicians, of all stripes, are always trying to expand their power further, have more control over more things. Whatever they say in public, you have no idea what your favorite politicians are really like. Your favorite op-ed columnists is not presenting the insights you think. This is just another part of the system they are running. We should be highly skeptical of these kinds of things. Where is the drive behind this coming from? Someone in politics has crafted this narrative and thinks it will be a winner. In the meantime they are not looking at a million other issues that have far more impact on far more people. The only way you get what you want from this system is to force it.

I built a simple tool that tracks prices for 500+ hard drives and SSDs.

Shows:
- Current prices across drives
- 90-day price history
- $/TB comparison
- Which drives are actually good deals right now

Made it because I never knew if a drive price was good or if I should wait.

I think this tweet sums it correctly doesn't?

A +6 jump on a 0.6B model is actually more impressive than a +2 jump on a 100B model. It proves that 'intelligence' isn't just parameter count; it is context relevance. You are proving that a lightweight model with a cheat sheet beats a giant with amnesia. This is the death of the 'bigger is better' dogma

So why was Elon begging to visit Epstein island years after Epstein was already convicted and sentenced and registered as a sex offender? That’s what the emails obtained by the DOJ show - Elon reaching out to Epstein to ask about when the “wildest party” would be. Let’s not be naive - he was asking to attend parties for the obvious reason.
