Show HN: Jqueue: A job queue that runs on a single JSON file
by jeeybee | 2026-02-24 23:14:45+00:00
I built a Python job queue that stores its entire state in one JSON file on S3, GCS, or your filesystem. No Redis, no RabbitMQ, no Postgres. Just object storage.

How it works

Read the JSON file, modify it in memory, write it back with compare-and-set. If two workers race, one wins. The loser retries with fresh state. No locks needed.

Israeli settlers are despicable, but even in current government those who support them are minority freaks(who Hamas has empowered very much after October 7th).

Also it is a two way street, there is also a problem of Palestinian settlers, which while I do want to highlight is separate and in no way justifies the Israeli ones, is still a real problem and harnesses a lot of bad publicity when Israel destroys said illegal settlements.

Replying while @dang is editing - so might be talking past current parent:

I suppose I shouldn't be surprised that Arc/clarc would be modified as news is modified (Arc sort of being built around news in the first place).

I just wouldn't expect there to be hn specific sauce in clarc that would make sense to excise if opening up clarc; AFAIK it's been stated that there's some secret sauce wrt fighting spam, detecting voting rings and so on...

Then again, thinking more about it, it sounds reasonable that some of that might land on the Arc/clarc side, not in news.

[Ed: I think that turned out quite well]

it's probably a good thing to have domestic advanced manufacturing if only to have real-world testbeds for development of advanced automation technology.

it's cool and all that boston dynamics can do what they do, but i wonder if one reason why the chinese robotics industry is so advanced is because they've been able to test in production on real production lines, experiment with dark factories and learn a ton in the process.

it's kind of funny when you think about it. both the west and east are facing down the same set of potential problems that come with real automation of industries that have served as true economic dynamos for decades.

From the report:

> The report by Earshot and Forensic Architecture reconstructs, minute by minute, how the massacre unfolded. Using video and audio recordings from the incident[1], open-source images and videos[2], satellite imagery[3], social media posts[4], and other materials[5], as well as in-depth interviews with two survivors of the attack[6], the groups were able to digitally reconstruct the scene and events surrounding the massacre.

So out of multiple "sources", some of which aren't even mentioned ("other materials"?), only the first one is actually from the scene. Sources 2 through 5 are not from the actual scene. The "interviews" are eye witness accounts which are extremely unreliable in this context, especially in a gunfight in the dark.

I don't know. Doesn't seem all that high-tech impressive or even reliable to me. There's also a huge problem with the team conducting this report being consistently biased in their terminology, having team members with titles like "activist", and having researchers from Ramallah and other places who are clearly a side in the conflict.

I will be glad to see a neutral, journalistic research of this incident trying to actually get to the truth and determine if there were hamas militants in the convoy, rather than see some self proclaimed activists play with google maps.

Well, um.. Forgive me for not being in the market for a showerhead in the last few years and / or not knowing about this one company that I didn't see at Home Depot/Lowes when I did buy a couple of them?

I admit I'm probably an outlier, but in terms of durable goods, I'd pay 30-50% more for lots of things if they were "made in the USA" or "made in Canada" (any western country) and it meant something - like, better parts availability, repairability, documentation, support, etc. Not all of them, but something - AND, it was paying domestic imports / reducing imports.

I'm not living paycheck to paycheck, but I'm not wealthy.

A shadowy cabal that gets together for debauchery and rape is quite different from a shadowy cabal that unleashes a pandemic as part of an evil plan to force everyone to get vaccinated. Why would they even want to do that? I get why people want to engage in debauchery. Why would they want to force vaccines on everyone? The basic concept makes no sense.

> From where I sit nobody is questioning that the Israelis are supposed to be the good guys in this story.

That's a baffling claim.

Israelis emphatically not being "the good guys in this story" is a very mainstream (though not necessarily majority) view in every country in the world, possibly with the exception of Israel itself.

I tried many different setups and have landed on my perfect one finally.

I use 1 4k screen at 125%. This is where I primarily work. My second screen is a 15 inch 1080p monitor. It’s primarily chat/email and the screen I share when I need to screen share. I have to work on to many things at the same time so virtual desktops become to much to juggle. I do stick to either a 50/50 split on the 4k or a quad split.

At one point I had 8 monitors and now thinking back I was insane, but it was fun.

> They will agree to make some high margin simple to assemble thing in the US to appease government

They'll also hold a ribbon-cutting ceremony with maximum fanfare, at which they'll be sure to fawn over Donald Trump, let him ramble at length, and maybe give him some sort of shiny award.

Let's call it The Steve Jobs American Technology Greatness Prize. It'll be a blindingly flashy PVD-gold-plated 12" silicon wafer with a Mount Rushmore-style portrait of Jobs and Trump etched into it.

It's not a defense, it's a constant reminder that one side is bad or worse. As someone who believes in modern values and society, I think it's very important to acknowledge all of the recent events.

If you care about the victims, you should also care about the victims at the music festival too. Because they're one and the same, innocent people who were murdered for stupid ideology.

Let's say Anthropic refuses to do this. What actually happens next?

Or lets say they refuse and the government comes against them hard in some way, and Anthropic still really doesn't want to do it, so they just dissolve the entire company. Is that a potential way out, at least?

I mean, I realise they'd be losing billions by doing that and putting thousands out of work, but given that unaligned military AI could destroy the world...
by atleastoptimal | 2026-02-24 23:17:09+00:00
It's kind of funny that METR is known primarily for both the most bearish study on AI progress (the original 20% slowdown one), and the most bullish one on AI progress (the long-task horizon study showing exponential increase in duration of tasks AI models can accomplish with respect to date of release).

In either case, it seems people often bolstered preexisting views on AI to whichever study most affirmed them (for the former, that AI coding models didn't actually help and created a mirage of productivity that required more work to fix than was worth it, the latter that AI models were improving at an exponential rate and will invariably eclipse SWE's in all tasks in a deterministic amount of time.)

I think the truth is somewhere in the middle. Just anecdotally we've seen multi-million dollar fortunes being minted by small teams developing using 90% AI-assisted coding. Anthropic claims they solely use agents to code and don't modify any code manually.

This is a valid point. However, the conclusion depends on the fact that the people in power have the information and wisdom to make the choices required stay in power. Which has been mostly true (so far) in US history.

Historically this has very much not always been the case (citation: any revolution)

But "oppressive power", via information control or military/police control is also a factor. If AI is able to give the ruling incumbents more power, that shifts the equilibrium between popular sentiment and people in power.

I think Churchill's main point is that they neglected teaching English well. However, if you read him and politicians of the era, you will find plenty of classical references. If we dig into classical history it is quite amazing how many of the same things we see. I was reading something about how certain cities in Asia Minor (modern Turkey) were spending more and more money on civic vanity projects and having to be bailed out by central government in Rome. Very similar to patterns today.

> Many people do not understand the vast difference between residential construction quality and the quality that mega corps get.

It’s not limited to mega corps. Commercial construction is built to a higher standard. Some times you can buy commercial grade hardware and materials for your house if you want.

Larger buildings are also more robust at the foundation because it needs to be so much stronger. That thick concrete is necessary, not a luxury.

It's not like there's much of an alternative, but that's irrelevant anyway. Android is becoming more like an iPhone, and as long as the OS is able and willing to reliably report to anyone asking just how tightly it is locked down, we have zero choice in the matter, because increasingly many important apps (like bank and government apps) plain refuse to work if device is locked down less than it could be.

yes, that's the point, but you will rise the ceiling the more paying users you get. as opposed to having to deal with per-user limits, you have a global limit you fully control

for example, i have 900 users, 7% paying, but it's 3-6 new users per day, it's manageable at 5 credits per user per day (non-renewable), and 20 communal (so in theory 4 users)

when i grow, i just raise the communal credits from 20 to, let's say 100, so 5x more free happy users per day. i think it's beautiful in its simplicity and flexibility

The war on terror, it might have been criticized in hindsight, but let's not pretend it was unpopular at the beginning...

It's been awhile since I've been in high school, but even back then standard public education was to discuss the topic very respectfully and to question the mainstream narrative that "more lives were saved because of it". It's not uncommon for US High Schools recommend Barefoot Gen as a supplemental reading on the subject. Americans largely feel complicated about Hiroshima and absolutely do not view strong critique of it as "whining".

So yeah, I'm sure many people in Israel have a complicated view of the events that happened post October 7 too. Yet people will mostly ignore all of that and go completely out of their way to criticize basically everything Israel has done.

I'm quite partial to it all, I just hate the hypocrisy.

I'm a principal at Fly.io (W20). I'm familiar with the dynamic.

I don't invest in tech companies.

Most funded tech companies don't return funds to investors. Noncontroversial claim.

Investors invest in tech companies as a/in a portfolio strategy. They don't expect any one investment to succeed, and they allocate to the asset class in part to get exposure to decorrelated assets.

That's not at all what retail investors are doing.

You keep talking about accreditation. The companies you want to invest in don't want your money and they don't care that you're accredited.

This requires knowing what to compile, which these engines don't really do, because the necessary data is pooped out by arbitrary game logic / scripts. That's why precompiling shaders in e.g. UE5 basically relies on running the engine through a pre-recorded gameplay loop and then making a list of the shaders/PSOs used; those are then pre-compiled. Any shader not used in that loop will cause stutter. A newer UE5 technique is to have heuristics which try to guess which PSOs might be needed ahead of time.

There's this article from Unreal on the topic: https://www.unrealengine.com/en-US/tech-blog/game-engines-an...

If you read their proposed solutions, it's quite clear they only have patchy workarounds, and the inability to actually pre-compile the needed PSOs and avoid shader and traversal stutter is architectural. It should be noted that these engines are also stuttering on console, but it's not as noticeable since performance is generally much lower anyway.

if you look at Mac Mini design, it didn't change much in many years (2011-2024 is practically the same)

https://preview.redd.it/always-loved-the-design-of-the-mac-m...

so maybe that's the reason they chose it. They just designed a new iteration in 2024, so maybe they don't expect much change for a while.

If you were correct, it would be trivial for Apple to reshore the manufacturing. But it’s not. Because what China has proven is that, when you outsource the “low margin low skill” stuff, everything going up the chain will follow. China used its low-margin low skill work to bootstrap the rest of the stack, and now they can make air to air missiles with range exceeding US missiles: https://militarywatchmagazine.com/article/china-first-close-...

Margin is the wrong way to look at it. Law and finance are high margin work. But lawyers won’t help you win a war.

Yes, there will always be someone willing to buy on price alone, but that doesn't mean that there aren't also people who will pay more for better service. To wit: Spirit is financially fucked, mainline carriers are in better condition. The existence

I think the real thing is that - in North America at least - there is a pretty good chance that a mainline carrier will treat you poorly, hit you with unexpected fees, jam you into a tiny seat, etc.

For many people, the difference between an ultra-low cost carrier and a mainline carrier is whether they have to walk through first class on the way to their seats. If you are going to get treated like cattle and upsold on everything anyway, might as well save a few bucks.

Given the choice between Singapore Airlines and United, I'll pay extra for SingAir because I KNOW the service will be better. Given the choice between United and Southwest, I'll just get whichever flight makes the most sense since I don't really expect United to offer better service.

I might be misreading your comment so that being said:

If you wear a body cam because you feel threatened, hopefully you tell others that you're potentially recording them. The other catch is that the smart glasses do more than simply record video such as facial recognition and so on. Often these are things that have privacy ramifications that neither the wearer or the observer know exactly.

> an EMP that disables all nearby camera sensors for 10min or so

Some years ago, there was a guy that got arrested (may have been in Chicago), for riding on the train, and running a cellphone jammer, because he hated people on the phone, while on the train.

Might be considered somewhat similar. It could definitely earn you a beatdown, if someone catches you.
Show HN: WaveGuard – Anomaly detection using wave physics simulation (GPU, MCP)
by waveguard | 2026-02-24 23:20:11+00:00
I built an anomaly detection API that uses wave physics (Klein-Gordon equation)
instead of ML. You feed it normal examples + suspect data in one stateless call
— no training step, no model management.

How it works: data gets encoded onto a lattice, a wave equation evolves it on
a GPU (NVIDIA T4), and anomalies show up as regions where wave energy
concentrates. It also returns the top features explaining WHY each point was
flagged.

What's different from sklearn/PyOD:
- Stateless: training + inference in one API call
- GPU-accelerated: CUDA kernels, not Python loops
- Explainable: per-feature contribution scores, not just a number
- Works on anything: JSON, time series, text, tabular

Free tier: 100 scans/day, no key needed.

Python SDK: pip install WaveGuardClient
MCP server: works with Claude Desktop / AI agents via Smithery
Docs: https://github.com/gpartin/WaveGuardClient

Try it in 4 lines:
from waveguard import WaveGuard
wg = WaveGuard()
result = wg.scan(training=[{"cpu": 45}, {"cpu": 50}], test=[{"cpu": 99}])
print(result.summary)

It's a tough sell after decades of propaganda. According to the CDC, over 75% of Americans are seriously out of shape[1], and 40% are obese[2]. They typically spend an hour a day commuting by car, which robs them of an easy opportunity to get a little exercise (and which is also physically dangerous in an immediate sense and a form of long-term psychological torture as evidenced by driving behavior at rush hour).

Israel killed UK army veterans, it was a targeted operation and a precision strike to send a message.

It was covered by UK media for a short period and they would gloss over the veterans and focus more broadly on WCK, there is lots of examples of UK media weird coverage like this which no doubt was intentional. It was also barely spoken about by UK politicians

China is not state-subsidized / running at a loss on materials so much (although they probably get cheaper rare earth minerals) - they're running at a loss on wages. There's no "loss" there - the state doesn't have to buy labor and sell it to the companies to put into the product at a loss - the companies simply pay less overall in terms of labor, because that's the prevailing rate.

Even if you paid 5% more for materials for an iphone but could pay 50% less for labor than China, you could probably beat China.

How does the state sponsoring come in? The state represses the people and the wages and prevents them from leaving for greener pastures in many cases, which benefits the corporations.
AI isn't killing SaaS – it's killing single-purpose SaaS
by JB_5000 | 2026-02-24 23:20:45+00:00
Over the last year I keep seeing “SaaS is dead” takes. I don’t think that’s what’s happening.

What seems under pressure isn’t SaaS as a model. It’s narrow SaaS built around a single capability that AI can now reproduce cheaply.

If your product is basically a thin wrapper over a model, or differentiated mainly by features rather than workflow integration, the moat feels weaker now. AI compresses build time dramatically. That means more competitors, faster cloning, and lower switching costs.

But SaaS that is model-agnostic, deeply embedded into workflows, or acts as connective tissue between systems looks much more durable. Integration, distribution, and trust don’t commoditize as quickly as features do.

It feels less like SaaS collapsing and more like a sorting event. Thin wrappers get squeezed. Infrastructure layers and integrators get stronger.

Curious if others building right now are seeing the same shift, or if I’m over-indexing on AI-native workflows.

Not everyone. I'm sure I would go for the "just shoot him" option. I'm totally a non-team player. I've once even attacked a PE teacher who really pushed me too hard.

I'm on the spectrum of course but I'm pretty sure I know why this isn't common in wars: people like me wouldn't make it through the medical let alone basic training. The military is actually really good at filtering us out because sooner or later we melt down at the worst possible moment. They literally told me this when I had to do the medical.

Personally I think the world would be a lot better place if people weren't so inclined to follow orders. A lot of atrocities have been committed in the name of defense, a flag, a church etc.

I was brought in tangentially to add some custom stuff on top of a Next.js app. Struggled for days with the most obscenely inflexible bloated mess before hitting an issue requiring a feature leading me to a ticket, where one of the original authors posted a myopic essay-length presumptuous treatise explaining why the feature was wrong and the submitter was bad for wanting it because, reading between the lines, the author didn't have enough industry experience to understand where that feature could be essential.

I have no idea how Next won the hearts and minds of so many, it is steaming garbage with all the aesthetic of an abattoir industrial carcass shredder that has been in use 24/7 for 10 years. I'll happily be polite when folk talk about using it, but make no mistake, somewhere internally a write-only reputational fuse silently blows the moment it is mentioned. If AI was not justified for any other reason, then it's to zero shot port Next apps into basically any other framework
