> If you give a robot the ability to delete production it’s going to delete production

If you give an intern the ability to delete production, it's going to delete production. But to be honest you can as well replace "intern" or "robot" by human in general. Deletion in production should have safety layers that anyone cannot accidentally do it, specially without the ability of rolling back.

Hey Andrew thanks for the feedback

We know that the main barrier to switching is just time and ease of use, so we deliberately built this to have the same operational burden as using your current treasury product

Palus links straight to your bank account just like Mercury, and we'll also allow you to set up rules for moving money around!

That said, if there's any other features that really keep people tied to their current products we want to know about it. Our goal here is to build something that actually cares about the fact that you're a startup with limited time to care about yields, and not just throw your money in a generic fund and forget you exist

I can't say I'm as conspiratorial as you.

I don't really know how these systems work, perhaps I shouldn't speak without research.

But it seems like a pretty basic error.

The base has looks like 5 buildings in an L shape. 4 buildings where hit in an L shape.

I can imagine the sites were picked from a satellite image and the wrong building was marked.

Or in flight from the camera the wrong buildings were marked.

It is our arrogance that we can blow up hundreds of buildings that makes us try and see meaning behind these mistakes.

Instead we should just be far more cautious about blowing buildings up because these mistakes are inevitable.

The perfect just war simply does not exist.

I agree with your basic premise that prospective employers should have a financial disincentive from wasting candidates' time. The problem is that charlatans and scammers could just keep applying to every possible employer and in about 3 weeks the entire industry would collapse.

The solution needs to be a bit more robust than that. Simple is great but not when it doesn't work.[1]

One of the best contract stipulations I've ever come across was that Company would agree to take on Recruiter's Candidate for 2 weeks of probation, and if it turned out that the Candidate was so bad that they needed to be fired immediately, Recruiter had to pay Company for those 2 weeks. So Recruiter was on the hook for double, unless they passed the penalty on to the Candidate. (Which I'm not sure was/is legal.)

I can see how tweaking that just a bit and applying it to the probationary period can protect the employer. Now the FizzBuzz failure has a very real risk if they lie, cheat and steal to get hired. But how do you protect the candidate from having days of their time wasted with interviews and such without turning the company into a cash cow for scammers?

Most employers can afford to be very inefficient at interviewing as long as they get a usable body in the door eventually. How can that be structured so that both parties have an incentive to make the process efficient?

Fair! Growing user trust is definitely one of the biggest challenges building in this space.

For what it's worth, we don't hold users' funds ourselves; we use an SEC-regulated custodian (Alpaca) with the assets legally held in your name. And we're working on building transparency measures, like detailed views into your account's specific holdings of underlying assets with verifiable attestations, third-party auditing, and frankly any other measures that our customers would want us to.

I know putting company money into a new product requires a lot of trust. Like any product you're still exploring, I'd encourage you to start small, try us out, and grow your position over time as we earn your trust. And if it helps you trust us, I'd be happy to get on a Zoom call or meet IRL.

Will you PLEASE stop promoting UEFI and ACPI?! These are closed-source blobs that the manufacturers will never update and have complete control over the system at ring -2. Why would you even consider it?

Device tree does the same thing and it's open source. Even if you only extract it in binary form a proprietary kernel or uboot, you can decompile it very easily.

As long as you don't have a MAGA bumper sticker, I doubt it. Most Canadians have some American friends, so we're usually pretty good at separating "Americans" from "the American government".

Especially in Vancouver, most people should be pretty aware that anyone with Washington/Oregon plates (which I'm guessing is what you have) probably hates Trump more than they do.

If the AI is good enough to truly implement the whole thing to a similar level of reliability without copying it then who cares. At that point you should be able to decompile any program you want and find enough information inside that an AI can go write a similar quality program from the vague information about the call graph. We've transcended copyright in computer code.

If it can't and it costs a bunch of money to clean it up then same as always.

OTOH if what is actually happening is just that it is rewording the existing code so it looks different then it is still going to run afoul of copyright. You can't just rewrite harry potter with different words.

Note that even with Google vs oracle it was important they didn't need the actual code just the headers to get the function calls were enough. Yes it's true that the clean room isn't required but when you have an AI and you can show that it can't do it a second time without looking at the source (not just function declarations) that's pretty strong evidence.

> Israeli and U.S. leaders have voiced hopes they would trigger an uprising, but Reuters found no evidence one was imminent

I cannot imagine where they thought this uprising was supposed to come from. Plenty of Iranians are unhappy about the current regime, but that doesn't mean they've got a new one prepared to replace it.

Even in Iraq and Afghanistan we started with at least a rough idea of what followed a regime change. In both cases it was corrupt and ill thought out, but at least it existed.

I'd always heard inverting a binary tree thrown around as some kind of absurdly hard problem. I took a look at it and it was trivial. I was able to do it on the first attempt with no preparation. (And the point of these interviews is that you study for them, right?)

It's a contrived scenario, but the whole point is that it measures min(a,b) where `a` is your ability to think, and `b` is your ability to prepare (and memorize answers ahead of time). (I'd personally try to find ways to measure `a` instead of `b`, maybe by asking questions people wouldn't have heard before.)

I’m not familiar with the “modern car” unit of weight.

“With an assumed average weight of 300 to 400 grams per book, the weight of around 15 modern cars is currently stored in Schröder’s detached house.”

350 grams x 70,000 books = 24,500 kg. About 54,000 lbs.

Can a ‘typical’ house bear that weight??

Disheartening to say the least. A cache like that would sure to a have single volume that would more than pay for the price to pay to have them moved and stored for a year… the idea that there are countless volumes of that caliber most likely in a collection like that means whomever is responsible is literally throwing money away… based on what you’ve described I could easily see a collection like that fetching at least a hundred thousand dollars, maybe substantially more.

Can’t believe how many people are commenting without looking at what the chart means. We’ve lost 50k jobs last two years after decades of adding 100k+ every year including the pandemic highs of 300k+ per year. Total employment remains way above 2000s, 2008 and 2020 unlike the title suggests.

I do think there is a strong possibility the people in charge in the US government believe an Iran state sponsored terrorism attack would be a political benefit to them. Such things boost support for the sitting President, and could also give political cover for additional authoritarian acts to help them retain power. Would they do the school attack on purpose? Maybe? But for sure they keep the war going until they generate the response they are looking for...

This is unironically my favorite kind of HN comment: to say something incredibly rude and/or condescending but wrap it in the right kind of thoughtful language to qualify as HN nice

The original punchline ("you don’t learn the actually valuable lessons.") was just a bit too sharp, so you even edited in a psuedo-clarification which actually just repeats that punchline but in a softer way, masterful!

You expect more nonessential roles and slower hiring in a slower growing economy, especially if companies only hire for full-time roles.

For example, your company might need a full-time network admin once its network grows to a certain size and complexity. You won’t hit that level for three years but you’d hire the perfect person now if you found them even though they might be spending a lot of idle time scrolling Hacker News for the first year or two. At 5x the growth rate, you’d need that person within less than a year, and you might be less picky about whether they are coming from a TV or telecom shop.
Show HN: Hydra – Real-time ops dashboard for developers running AI agents
by marinerk9 | 2026-03-06 20:22:56+00:00
I built this because I was running Claude Code, a local LLM, and multiple
dev servers simultaneously and had no visibility into what was actually
happening. Activity Monitor is useless for this. htop has no context.

Hydra is a macOS desktop app (Electron + React + TypeScript) that shows:

- Which AI agents are running (Claude Code, Codex, Cursor, Gemini) and
their status
- Per-process CPU/memory with project grouping
- Port-to-process mapping
- Git repo health across all your projects
- Network bandwidth per process
- Security posture via a built-in scanner
- AI briefings from a local LLM (I use LM Studio with Qwen 35B) —
no cloud API needed
- Claude Code usage and cost tracking

Everything runs locally. No telemetry, no accounts, no cloud dependency.

GitHub: https://github.com/kunalnano/hydra

Happy to answer questions about the architecture or the local LLM
integration approach.

Perhaps if an ETF holds similar underlying instruments. It is unlikely this impacts Blackrock more broadly or other unrelated ETFs.

Stepping back, the idea with private credit was to move a lot of lending and credit risk taking away from the banks. Because if the bank fails, then it causes risk to the financial system. If a private credit fund does badly, you have sad investors. But the broader financial system is not imperiled.

And there will always be periods where credit does badly. It is the nature of these markets and lending.

TBC, I think the private credit guys got over their skis over the last 5 years and we'll see some sad investors in the next few years.

>If you need to wait YEARS to hire someone with some specific experience, I can guarantee that you really didn't need that person. You're doing this just to check some specific artificial goal that has little to do with the business.

There's a difference between "critically needing" and "would benefit from."

If you can find the specialist who's done what you're doing before at higher scale and help you avoid a lot of pain, it's awesome. If not, you keep on keeping on. But as long as you don't start spending too much on the search for that candidate, it's best to keep the door open.

According to that article (it's hard to understand their numbers) it seems around 50 (with the remaining being detained for interference?).

According to this [1], ~68k have been deported. So, around 1 in 10,000 (or 0.07%). Next question would be, is 1 in 10,000 reasonable? You would have to compare to other countries or maybe police operations (like I experienced).

The best candidates would have that question wrapped up in 5 minutes. Like they're not even having to think about it, which is honestly all I cared about testing for -- do something really easy really fast so I know you're not BSing me, and then we can move on to just having a conversation about your past experience.

One of the worst guys took 20 minutes, with me having to coach him through it the entire time. It was a true exercise in patience, but I don't mind helping people learn new things. When he got his rejection email, he actually complained to the recruiter because he thought he did really well. Dude...

A gas furnace produces at most 1 kWh of heat from 1 kWh of gas. A heat pumps produces 3-4 kWh of heat from 1 kWh of electricity. If electricity is 3x as much as gas per kWh the heat pump should be less expensive to operate.

Plus, it also gives you AC which comes in handy if you live someplace where you want AC.

> A compiler is deterministic.

Not usually they aren't. They can be made to be, but it requires extra effort and tradeoffs. Hence why there is a lot of work put into reproducible builds — something you would get for free if compilers were actually always deterministic.

Unless you are taking a wider view and recognizing that, fundamentally, nothing running on a computer can be nondeterministic, which is definitely true.

The same way we solve election fraud:

Show ID to get in the door. Match your ID to the voter roll, for that precinct only. 100% paper ballots, counted by hand at the end of the night, before they leave the premises, permanently recorded and witnessed at that moment. No exceptions, no irregularities tolerated. Anything else, somebody goes to jail right now.

Does that sound far-fetched? It's not too different from what I did to get my last IT certification. There are valid criticisms of the certification racket, but one thing is for sure -- people are not showing up to Pearson testing centers who can't write FizzBuzz and walking out with a cert 40 minutes later....

I don’t know what compels someone to take a twitter blue check as an authoritative source. But there were people peddling bizarre rumors without any real evidence
Show HN: Mantle – Remap your Mac keyboard without editing Kanata config files
by gsteezy | 2026-03-06 20:26:58+00:00
I built Mantle because I wanted homerow mods and layers on my laptop without hand writing Lisp syntax.

The best keyboard remapping engine on macOS (Kanata) requires editing .kbd files which is a pain. Karabiner-Elements is easy for simple single key remapping (e.g. caps -> esc), but anything more wasn’t workin out for me.

What you can do with Mantle:
- Layers: hold a key to switch to a different layout (navigation, numpad, media)
- Homerow mods: map Shift, Control, Option, Command to your home row keys when held
- Tap-hold: one key does two things: tap for a letter, hold for a modifier
- Import/export: bring existing Kanata .kbd configs or start fresh visually

Runs entirely on your Mac. No internet, no accounts. Free and MIT licensed

Would love feedback, especially from people who tried Kanata or Karabiner and gave up
Show HN: Contexa – Git-inspired context management for LLM agents
by 0x0003r | 2026-03-06 20:27:10+00:00
Hi HN,

I’ve been experimenting with building LLM agents and kept running into the same problem: managing context gets messy quickly. Prompts grow, reasoning steps get lost, and it's hard to reproduce or roll back agent behavior.

So I built Contexa, a small open-source project that treats LLM context a bit like Git — with ideas like snapshots, branching, and history for context.

The goal is to make it easier to:

track how context evolves

experiment with different reasoning paths

reproduce agent behavior

It’s still early, but I’d love feedback from people building LLM tools.

I'm curious: has someone done a lengthy write-up of best practices to get good results out of AI security audits? It seems like it can go very well (as it did here) or be totally useless (all the AI slop submitted to HackerOne), and I assume the difference comes down to the quality of your context engineering and testing harnesses.

This post did a little bit of that but I wish it had gone into more detail.

I am running local offline small models in the old fashioned REPL style, without any agentic features. One prompt at a time.

Instead of asking for answers, I ask for specific files to read or specific command line tools with specific options. I pipe the results to a file and then load it into the CLI session. Then I turn these commands into my own scripts and documentation (in Makefile).

I forbid the model wandering around to give me tons of irrelevant markdown text or generated scripts.

I ask straight questions and look for straight answers.
One line at a time, one file at a time.

This gives me plenty of room to think what I want and how I get what I want.

Learning what we want and what we need to do to achieve it is the precious learning experience that we don’t want to offload to the machine.

Admit what? Trump is open about the racial nature of deportations, and witnesses say the same.

If you want to bring stats into it, the baseline is to try to disprove what everyone already knows.

Assuming something is false just because it makes Trump look bad, in your eyes, is a very biased take on the world. Just listen to his own words, he's not ashamed of the racial nature of the deportations, it doesn't "make him look bad" because its a feature not a bug.

Some quantification is very helpful. We're going to have a very different conversation if the architecture you built was serving 1 million users as opposed to 1000 customers.

It's the useless quantification that turns resumes into noise, combined with making claims that you changed revenue by yourself.

> You have to only write down things that moved some quantifiable business needle like revenue or signups, even if the link to that needle is tenuous. Obviously, this ends up penalizing hard working, talented devs who don't happen to be working in areas where wins are easily quantifiable.

Every hiring manager knows this game and sees right through it. You can't read 1000 resumes with claims of "Increased revenue by 13% by" followed by something that clearly was not the reason revenue increased 13% to become numb to it.

Nobody believes these.

The somewhat useful quantifications are things like "Reduced cloud spend by 50% by implementing caching". This can spark a conversation about how they diagnosed they issue, made a transition plan, ensured it was working, and all of the other things we want to hear about.

I always wonder when people tell these stories exactly what the metric is.

I've been around the block for over 3 decades. I've had a number of high level positions across both IC and management tracks. These days I'm very hands on keyboard across a number of clients. If you asked me to write a basic for loop or if statement, there's a small chance I'd flub the exact syntax if writing on a whiteboard. Both because I bounce between languages all day and wires get crossed on the fly, but also the standard interview pressure type arguments. Whereas if the test is "does this person understand what a for loop is and how it works?", then yes, I can easily demonstrate I do.

In real life I'm not going to take an interview where there's not already that degree of trust so if that questions comes up something is already wrong. But I'm sure there are interviewers in the world who'd fail someone for that.

> That said, I am not aware of any weapon which was developed specifically for use against a less technologically advanced adversary, most novel weapons are developed for use against peer-adversaries.

This is a strange take that I didn’t expect to hear. I suppose that the strongest defensive systems do require the most sophisticated offensive systems to defeat, in theory. But there exists asymmetry there as well ($50k drone destroys $1B radar).

My take on weapons development is that there were plenty of mass killing (or mass punishment) devices developed specifically for use by colonial powers against indigenous peoples. This happened alongside weapons development for weapons intended for, as you put them, peer-adversaries.

Revolts happened, and colonial powers needed effective ways to keep indigenous peoples enslaved.

To provide a different framing, I’m more of a builder and I’m happy to maintain too. What I’m not happy with, and have left jobs over, is being put into a box or becoming overly siloed.

Large companies tend to over specialize and that’s where I see the “I’m a builder” types fall apart. That takes away agency, lowers skills, and removes variety from work. That’s when it stops being fun to me.

I would hope most people with the builder architype are otherwise fine to keep building and maintaining.

That's fair. But to your point, the problem we see is that banks' treasury products take advantage of founders who (rightfully) don't want to think about their treasury yields.

That's why we designed Palus to be as simple as possible to use. If you check out our demo video, you'll see it's super straightforward. Setup takes <5 min and then you don't have to think about it anymore. We're also building out automatic sweep functionality, so then you REALLY won't have to think about it.

Given the significant increase in returns on a large treasury, we think it's worth the small amount of effort.
