I’ve been frustrated by how opaque agentic commerce is right now. Shopify and Google launched the Universal Commerce Protocol (UCP), but for a developer, it's often a black box in production. You might have your manifest at /.well-known/ucp, but is Gemini actually reading it? Or is it getting silently dropped by a legacy firewall rule?

I built this extension as a lightweight debugger for my own agentic workflows. It’s like Waze for UCP—as we browse, the community is crowdsourcing a map of agent-ready domains. We’ve verified 508 domains so far.

Key features for devs:

Zero-Click Workflow: Uses badge icons to show status instantly (Green = ready, Gray = not detected).

Instant Manifest Debugging: Surfaces HTTP status, response times, and version metadata for UCP manifests.

Gemini Readiness: Checks specifically if the Gemini agent (and others like GPTBot) can reach the store or if they are blocked by robots.txt/WAF rules.

Privacy-First: No tracking, no data selling, and minimal permissions (activeTab only).

You can try it out without an account or signup. I'd love to hear what other signals you'd want to see in the debugger, or if keeping it this lightweight is best!

Few thoughts: in context it's not nuts at all:

- moot was fundraising for his VC backed startup during the years the emails are in, and he was likely connected via mutuals in USV or other firms. These meetings were clearly around him trying to solicit investment in his canv.as project.

- /pol/ was /new/ being returned; the ethos of the board had already existed for a long time and the decision to undo the deletion of /new/ was entirely unsurprising for denizens at the time, and was consistent with a concerted push moot was making for more transparency in the enforcement of rules on the site and fairness towards users who followed the rules. /pol/ didn't start a culture war at this time any more than /new/ had previously - it just existed as a relatively content-unmoderated platform for people to discuss earnestly what would get them banned elsewhere.

Growing Anti-vax sentiment results in a gradually falling fraction of immunised population, Measles is an infectious disease with about 20:1 ratio, but obviously incidence is somewhat random, so a population with only 80% vaccination might go five years with no problem, while one with 90% gets unlucky and sees a rash of cases.

This grew as part of a general "Facts aren't true" era in which we've deployed powerful technology that's able to spread nonsense very quickly to gullible people. Trump is just another symptom and his rise to power in the US in particular is also a consequence of systemic flaws in the US government, a known bad model for governments.

The "facts aren't true" stuff is why the Nazis who have decided to protest near me have such a weird collection of beliefs which to them seem more or less equivalent. They believe 5G mobile telephones caused COVID, that trans people don't exist, that migrants are simultaneously both incredibly powerful, almost superhuman, and yet also very weak and entirely useless. None of this has to make any sense at all, indeed if you're the sort of person who wants to make sense of things you're not what they're looking for.

The wild thing is, the business prop is so clear - an llm built into your corporate data, with the same security, guard rails, grc auditing stack that protects the rest of your data. Why integrate and exfiltrate to an outside company?

But copilot is fucking terrible. Sometimes I ask it powershell questions about microsoft products and it hallucinates answers. Get your shit together microsoft, why would I use this product for any reason if it doesnt work squarely inside your own stack

It's honestly incredible to me that there are people who truly believe these two things are comparable:

> Mr. Dernbach, don’t play Russian roulette with H’s life

and post images of an arsenal, saying you need to buy guns for the upcoming election, and saying

> The time is right for a presidential assassination or two. First Joe then Kamala!!!

One is clearly a threatening murder towards public officials and showing the person taking steps to enact their plan. The other is a concerned citizen exercising their first amendment right. I have to believe the people saying these are the same are bots, because the alternative is just so pathetic.

I'll bite. Isn't as obvious to me as it is to you, I'm just a programmer, I don't know how the economy works. This is literally the first time in my life I heard anything about governments borrowing Yen like this and that this would become an issue.

I'm aware of an "AI bubble" and the over-concentration on the "Magnificent 7".

What else is obvious to people and why is the timeframe (next 4 years) so obvious?

It's incredible how much opposition there is in certain circles to the US enforcing its existing, most basic immigration rules. ICE is trying to deport people who are charged/convicted of violent crimes. When the CBC wants to ICE-out, their motivation is the US is now deporting criminals and that's what they're siding against.

That said, this article has no technical value and I'm not sure it belongs on hacker news.

There's an old joke that 9gag* only reposts stuff from Reddit and Reddit only reposts stuff from 4chan and 4chan is the origin of all meme culture. This joke was widespread enough to reach myself and my friend group back in the day, even though none of used 4chan or Reddit.

As the United States edges toward direct confrontation with Iran, the ripple effects are already reshaping South Asia’s conflict map. Pakistan’s Khyber Pakhtunkhwa and Balochistan—long plagued by insurgency—are now being weaponized as staging grounds for a new kind of war. IRGC-backed militias, freshly expelled from Syria, are redeployed with chilling precision: one contingent shields Chinese assets in Afghanistan, the other is absorbed into Pakistan’s counterinsurgency machine. What unfolds next is not just a regional escalation—it’s the convergence of global rivalries, sectarian fault lines, and strategic desperation. This brief exposes the hidden architecture of a conflict that’s no longer brewing—it’s igniting.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

This can be proven. Simply measure a population of typical social media users for relative measures of neuroticism. Then have an experiment population of healthy military leaders and police officers that have low social media use. The assumption is that the second population would score dramatically lower in neuroticism than the population average.

That establishes a of divergent populations baseline. The change their, such as deny, social media access or content. Measure the change to those two populations.

Assumed facts:

* social media access dramatically increases prevalence of anxiety and a state of dependency/addition. When true, removal of social media triggers addiction withdrawal that displays as emotional health illnesses.

* Populations that do not frequently make use of social media are not at risk of withdrawal.

* persons in high risk professions are typically conditioned into states of substantially lower neuroticism that population averages are not exposed to

Room allocations - from what I understand, there is a pre-assignment process for housing.

Students are “gaming the system” by getting access to buildings in specific locations (to lower their campus commute times) or by forcing single occupancy for themselves in 2+ occupancy dorms (which then creates a housing crunch elsewhere as you might end up with a triple or a quad elsewhere to compensate for it).

I think of social media as the fast food of the information landscape. It’s okay to have it a time or two a week but if it’s your entire information and entertainment “diet”, you’re going to feel sick.

Our brains aren’t designed to be lit up with dopamine every 5 seconds for hours on end nor are they designed for foods that are high in sugars, fats, and salts every day.

It seems to me that no person who makes any tough choices for the society could possibly be remembered well unless they live into the period of prosperity that follows.

For example, it is popular to talk about how bad the US debt servicing (15% of the federal budget) is, or the looming social security crisis, or the pension crisis and so on. But if someone raised the social security eligibility age or changed many pensions from defined benefit to defined contribution they would be villainized. Proposition 13 is often pointed to as a source of bad Californian incentives, but anyone who runs on repealing it will ruin their political career.

To say nothing of anyone who could possibly dare to oppose FARS rules, advocate for single-stair buildings, or allow insurance companies to charge sufficiently that they can operate in California.

Thatcher closed the mines and Trump wants to open the mines, so at least one of them must be loved for it. But predictably, neither are.

I’m a little impressed at how a company whose business model is to sell a product they developed in the 1990s over and over again while making inconsequential and non-breaking changes from year to year somehow still manage to screw that up. In my own opinion, they have always been a diabolical company. I’m glad to see them fail.

> A stand-your-ground law, sometimes called a "line in the sand" or "no duty to retreat" law, provides that people may use deadly force when they reasonably believe it to be necessary to defend against certain violent crimes (right of self-defense). Under such a law, people have no duty to retreat before using deadly force in self-defense, so long as they are in a place where they are lawfully present. The exact details vary by jurisdiction.

> N tokens looking at N tokens is quadratic

Convolving two arrays can be done perfectly accurately in O(n log n), despite every element being combined with every other element.

Or consider the even more basic sum of products a[i] * b[j] for all possible i, j:

total = 0
for i in range(len(a)):
for j in range(len(b)):
total += a[i] * b[j]

This can be computed in linear time as sum(a) * sum(b).

Your logic that 'the result contains terms of all pairs, therefore the algorithm must be quadratic' simply doesn't hold.

The way China manages it's currency is very different to how the US manages theirs.

China maintains strict controls on capital flows in/out. A reserve currency requires free convertibility. Holders need to move large sums instantly without permission. China has repeatedly tightened these controls during stress periods (2015-16 devaluation fears, for example).

Limited access to Chinese bond markets and equities for foreign institutions. Reserve currency status requires deep, liquid markets where central banks can park hundreds of billions. US Treasury market is $26T and extremely liquid. Chinese government bond market is smaller and less accessible.

Reserve currency issuer must run persistent current account deficits to supply the world with currency. China's economic model is built on export surpluses. They'd need to fundamentally restructure their economy.

It's hard to control for mere provision of social media access. Eg., if you're supposed to be out in the field all day, when are you mean to access social media?

Social media is, in that case, a replacement activity.

The question, which is i think unanswered, is whether and what its replacing in the lives of children. It may turn out to be: not much. That when taken away, children don't suddenly get more time, attention, socialisation, etc. instead, they just get less. Or that the kinds of tech hellholes theyre dumped in have purely passive interaction, eg., ipad kids.

AdBlock was child's play. We're going to have kernel-level condoms for every pixel on screen. Thinking agents and fast models that vaporize anything we don't like.

You and me both. No dating sites either, if I'm not crossing paths with someone in the wild through the course of my everyday activity, we are probably not a fit. I have found social media tremendously helpful at connecting people to real-life local activities, but I also had to move to a place that actually had enough of those for it to matter. There are plenty of places that never had much going on, and what social fabric did exist has been worn thin by social media, which offers a poor replacement.

I find that a bit of a weird point.

The goal of such sandboxing is that you can allow the agent to freely write/execute/test code during development, so that it can propose a solution/commit without the human having to approve every dangerous step ("write a Python file, then execute it" is already a dangerous step). As the post says: "To safely run a coding agent without review".

You would then review the code, and use it if it's good. Turning many small reviews where you need to be around and babysit every step into a single review at the end.

What you seem to be asking for (shipping the generated code to production without review) is a completely different goal and probably a bad idea.

If there really were a tool that can "scan the generated code" so reliably that it is safe to ship without human review, then that could just be part of the tool that generates the code in the first place so that no code scanning would be necessary. Sandboxing wouldn't be necessary either then. So then sandboxing wouldn't be "half the picture"; it would be unnecessary entirely, and your statement simplifies to "if we could auto-generate perfect code, we wouldn't need any of this".

This is great — manifest validation feels like the right “static” layer for the agentic web.

One nuance: a lot of prompt-injection / tool-abuse issues happen at runtime, when the agent is consuming untrusted content coming through perfectly “valid” channels (web pages, emails, tool outputs, even responses from allowed domains).

So I like to think: manifests cover the what (permissions / declared capabilities), but you also need something that covers the when — runtime content scanning + policy enforcement before that content is allowed to influence tool calls or sensitive actions.

Curious if you’ve thought about pairing this with runtime guardrails (e.g., classify/strip instructions in fetched content, detect credential exfil patterns, etc.)?
Show HN: Clux – Simple session manager for Claude Code
by zackham | 2026-02-04 19:00:47+00:00
I juggle 5-6 Claude Code projects and kept losing context when switching between them or when a terminal died. Built clux to fix that.

It wraps tmux to give you named, directory-scoped sessions with automatic context restoration via `claude --resume`. Start with `clux new api`, detach whenever, `clux attach api` later. Survives terminal crashes, reboots, whatever.

Has a TUI for browsing sessions and a streaming API (`clux prompt api "run the tests" --json`) that outputs NDJSON in real-time. I use it to control sessions from a Telegram bot.

Python, ~2k lines. Only needs tmux and the Claude CLI.

I would assume one major thing here is that many orgs only need a small subset of functionality from what most products provide. Many times, that small subset of functionality is only "good enough" in and of itself, but the org is paying the premium for the entire suite of whatever it is. This makes realizing that an LLM can get them to MVP and beyond much easier.

I feel like they are picking a lane. ChatGPT is great for chatbots and the like, but, as was discussed in a prior thread, chatbots aren't the end-all-be-all of AI or LLMs. Claude Code is the workhorse for me and most folks I know for AI assisted development and business automation type tasks. Meanwhile, most folks I know who use ChatGPT are really replacing Google Search. This is where folks are trying to create llm.txt files to become more discoverable by ChatGPT specifically.

You can see the very different response by OpenAI: https://openai.com/index/our-approach-to-advertising-and-exp.... ChatGPT is saying they will mark ads as ads and keep answers "independent," but that is not measurable. So we'll see.

For Anthropic to be proactive in saying they will not pursue ad based revenue I think is not just "one of the good guys" but that they may be stabilizing on a business model of both seat and usage based subscriptions.

Either way, both companies are hemorrhaging money.

> lack of time for parenting

The average father in present day spends more time with their kids weekly than the average mother did in 1960.

> helicopter parenting caused by breakdown of social trust

This one is more likely I think. Kids aren't able to just run around anymore.

> lack of infrastructure and provision of environments where children can be known safe in public

Kids can not safely ride their bikes a few miles across town. Fewer sidewalks, bigger cars. Distracted drivers. Its a death sentence.

You in particular are my main criticism of Occupy as a movement. They lacked any sort of structure, shunned it in fact, that would have ripped control of these resources away from you once it became clear that you disagreed politically with the vast majority of the people involved. That you were allowed to keep control of those resources is emblematic of how Occupy could let all that energy dissipate into nothing.

"Lockdown Mode is a sometimes overlooked feature of Apple devices that broadly make[sic] them harder to hack."

Funny to see disabling "features" itself described as "feature"

Why not call it a "setting"

Most iPhone users do not change default settings. That's why Google pays Apple billions of dollars for a default setting that sends data about users to Google

"Lockdown Mode" is not a default setting

The phrase "sometimes overlooked" is an understatement. It's not a default setting and almost no one uses it

If it is true Lockdown Mode makes iPhones "harder to hack", as the journalist contends, then it is also true that Apple's default settings make iPhones "easier to hack"
