I was running late for the last flight home on a Friday a handful of years back. Skipped a late lunch and got to the gate just in time to find out the plane is late too. We boarded the plane but after an hour they unloaded us. Turns out they couldn't open the "fuel flap" and were going to try a "cold reboot" to fix it. If that didn't work they'd fly in another plane from some other city. I was supposed to be home in time for dinner and to tuck my kids in, but I rolled in at 2am. The "reboot" actually worked, it just takes a bit of time. You can't be on the plane when it "reboots" because they turn off the AC and it heats up a lot.

I've wondered about that a lot over the years. I generally don't fly on Fridays after noon anymore, not for work, nobody wants to actually be there at that time. I'm really curious about the process. What kind of system integration has a fuel door system that is so tightly integrated to the rest of the computers that it requries a complete reboot to reset? Was that some mechanic's last idea? Was it from Boeing or Airbus? Is it in the playbook? Is there a more elaborate debug process and they short cutted by rebooting? Is there a fault log that will help fix the actual issue or is it just gone? I dutifully got on the plane that time but I've sort of concluded that in the future, I'd make some calls and just pay too much to spend the night at the airport hotel and fly the next day.

"So here's the thing Mr. F-35 pilot.... the plane needs ctrl-alt-delete but it will drop like a rock from the sky while the computers are booting up... so you need to hold down the power button for 5 seconds, like a solid 5 Mississippis and then all the lights will shut off. Wait another 5 seconds and the press the power button again and it shoooould boot back up... You'll hear a nice pleasant chime and see our logo on the flight control monitor and then after about a minute when the POST completes and it boots up, you should be back in action.." Everyone involved with all of that is just cut from different cloth.

I think it's a broader social problem. People also socialize less in private as well. Atomization, mobile entertainment etc.

> The way I see it is that corporate cultures have completely given up on investment in employees. No more tuition reimbursement, no more certification reimbursement, you’re a hired mercenary. They are telling employees straight to their face that they are replaceable temp workers who had better start using AI as much as possible or else they’ll get fired and be replaced with AI anyway.

Chicken-or-egg of course, but employees also tend to job hop much more than before (again, understandable if they can't get a raise otherwise), making investment less rational for companies. It's a self-feeding cycle. People used to work for multiple decades in the same place before that. But probably some MBA books derived that this is bad, because they become too crucial and too unique, bus factor things, you need more fungible cogs than that.

Even in friend groups people are flakier, romantic relationships are treated as more disposable etc. Of course all these have a flipside, they didn't happen without reason. A general shift away from a "high-trust society" model.

> Second, Starship is much more expensive for each launch attempt than Falcon 9 ever was

They are already reusing boosters, so it might already be cheaper than F9 before booster reuse. Once they start reusing the ships, it will be cheaper than F9 with booster reuse because F9 has to build a new second stage each launch.

> Fifth, the market for Starship is unproven

The market for Starship is proven by SpaceX itself. The Starship can add 20x the Starlink network capacity per launch as F9. There are currently around 100 Starlink launches per year, so the market couldn't be more proven.

I've always thought those kinds of large-scale search-and-replace diffs should not generally be expected to be reviewed. If a review is 1000's of lines of identical changes (or newly-vendored code), literally nobody is actually reading it, even if they are somehow able to convince themselves that they are.

I would rather just see the steps you ran to generate the diff and review that instead.

I don't have an opinion one way or the other on this, but I do remember it happened at least once before:

"Three-time gubernatorial candidate and billionaire B. Thomas Golisano is changing his home address to Florida to escape New York income taxes he says cost him nearly $14,000 a day."

That's from 2008 and I don't think he lived in the city, so maybe not exactly a perfect example but all he had to do was "change his home address"?

>> Sure, adding a cert to the SCADA server is trivial, it runs Windows Server and has a NIC that can access the Internet, but on the other NIC...there's a menagerie of 30 years of industrial oddities.

> Not gonna lie, all i hear is "i'm annoyed i was able to ignore the problem for 30 years but now i have to actually fix it".

You're not entirely wrong, but you're talking to the wrong guy. Clean-slate rewrites are some of my favorite best projects, and I hate dealing with legacy junk - but there's just not budget to keep everything brand new all the time.

Realize that when you flush the toilet, the reason the water level goes down is likely to be a municipal sewer system and waste treatment plant that must never stop...they replace mechanical wear items once in a while, but some of the controls are well over 30 years old. Same story at the clean water plant that fills the tank back up. An average consumer might replace their phone every 2 years, but industrial processes and infrastructure have much, much longer timelines.

The MCP clients are still missing some key features to get to a fully autonomous booking, but we are getting there:

- With MCP Elicitations (https://modelcontextprotocol.io/specification/draft/client/e...) the server will be able to secure ask for complementary info like your name, passport and even your payments details.

- With mcp-ui (https://github.com/idosal/mcp-ui), supporting MCP Clients could allow the server to re-create the same booking flow UI that you find today on an aggregator's website

A few years ago Peterpaul developed a lightweight object-oriented system on top of C that was really pleasant to use[0].

No need to pass in the object explicitly, etc.

Doesn't have the greatest documentation, but has a full test suite (e.g., [1][2]).

> it just happens to be a frequency near one we expect to be used as a signal.

What's the reasoning for this? I've seen noted that the Wow signal of 1420 MHz is near the hydrogen line frequency, and is commonly detected astrophysically.

So is the reasoning just that, if you want to send a signal, then you might choose this frequency because other civilizations will probably have detectors tuned to it?

But then the flip-side of that is that if you detect this frequency, then it's almost certainly natural origin, from the excitation of hydrogen.

> The first mars expeditions will probably be stocked with a thousand tons of gear, enough to easily last a guy 5 years.

> The Martian is a vision for a 2035 mission from 2011. We seem likely to beat that!

What, exactly, is that guy doing for those five years? We don't know how to terraform Mars, and it's questionable what having someone on the surface will add to the knowledge we have of surface composition. And then what? That equipment is still on earth - after it's built.

Oh, and how's he planning to get off Mars?

I would comfortably make a $100 bet that there is no chance that we have sent a manned mission to even orbit Mars by 2035, let alone are "settling" it.
Show HN: DataBot – Self-Hosted AI to Query and Visualize Data Using Language
by vvaezian | 2025-08-27 16:17:16+00:00
Hi HN!

I'm Vahid, and excited to share DataBot, a self-hosted data assistant that lets you query, visualize, analyze, and forecast data in plain language.

Backstory: Right after ChatGPT launched, I built a prototype chatbot for Metabase (a BI tool) to answer user questions with natural language. That experiment grew into an independent app — now a fully-fledged AI-powered data assistant.

What's different:

- Self-hosted: Full isolation and control over your data. No SaaS vendor, no third-party access.

- Feature-rich: Includes forecasting, NoSQL (MongoDB), JSON column support, Metabase integration, and data obfuscation — things rarely found in other tools.

- Affordable: Free for personal use. Business plans start at $12/user/month.

Technical details:

- Framework: FastAPI

- Data explorations/analysis: Uses GPT models to translate natural language into SQL or MongoDB queries, executes them, and returns results

- Visualization: Chart.js

- Forecasting: GPT models generate Python code, which runs securely inside the app

- Deployment: Docker or standalone bundle (includes app, Python, and local Postgres)

- Data support: SQL databases, MongoDB, JSON columns, Metabase dashboards

- Metabase integration: via Python wrapper for Metabase API (metabase_api_python)

Quickstart guide: https://databot.intellimenta.com/admin_guide/getting_started

GitHub Repo: https://github.com/Intellimenta/DataBot

One of Trump's primary objectives is destruction of the Fed, which is what gives the US Dollar status as the world reserve currency. His objective is directly aligned with Putin's, which should come as no surprise. They both realize that the very source of the US's power is the Federal Reserve. Don't take his actions as misguided - they are malevolent and intentional, without a doubt.

Something did change with Safari when handling lots of DOM nodes around the last major release of all Apple's operating systems.

I have an ever growing directory listing using SolidJS, and it's up to about 25,000 items. Safari macOS and iOS two major versions ago actually handled it well. After the last major update, my phone rendered it faster than an m1 MacBook Pro.

This is a deep dive into the massive subsidy war currently happening in China's on-demand delivery sector between Meituan, Alibaba, and JD.com. The article argues that this isn't just a simple market share battle, but a preview of the 'post-growth' era for tech giants, where they are forced into brutal, potentially value-destructive competition over low-margin territory.

It analyzes the three clashing business models (local network vs. traffic funnel vs. infrastructure) and the staggering financial costs (e.g., Meituan's 89% profit drop). The core thesis is that this might be a war with no absolute winner, serving as a cautionary tale for Western platforms like Amazon, Uber, and DoorDash. Curious to hear the HN community's thoughts on the economics of instant retail and the long-term sustainability of such subsidy-driven competition.

I'm sure it must have nothing at all to do with cultural stigma. If that were true we'd see signs of mental struggles in their home countries. In the US I'm sure all the model minority bullshit people project on them doesn't cause them any extra pressure or anxiety right?

Asian Americans are so successful that they certainly must not have disproportionately higher rates of suicide right? That might be a sign of some "impairment" going unaddressed! Or maybe you see the rate at which they're killing themselves as yet another metric of success? Those scrappy East Asians are just so good at doing stuff!

You basically want a makers meetup.

* Come discuss problems you are having with your code * Join in a Hackathon to see if the group can make progress on a predefined issue or project. * Learn a new language, everyone pulls a language from a bucket and sees if they can make Game of Life. Limitations require that at least one person there that knows the language enough to help with getting someone going

We had one of those for about 6 months, and I loved it. However finding spaces that would host us was hard.

What always happens with me is that I'll install the plugin, activate its trial ( as part of the installation process in my mind), then completely forget to get around to testing it until the trial is up.

I know it kind of falls under "user error," but I really wish these plugins had a metered trial period. Like 8 hours of actual usage instead of starting the clock from the time of activation.

Journalism's failure to adopt linking to sources etc in the internet age is kind of infuriating. I get it, back in physical newspaper/magazine days, linking wasn't possible, and it takes a while for new norms to change and habits to form, but articles have been internet-first for well over a decade at this point. It should be completely unacceptable not to have linking to sources whenever relevant. I'm not sure I have ever found a news article that makes finding the original source or subject of the article easy. Certainly not on mainstream news outlets.

The problem with fake socialists is that they suggest solutions that do not fix the fundamental problem with democracies. That there isn't democracy.

How will higher taxes guarantee that they will be used appropriately?

How are the people guaranteed that officials will not be corrupted to divert that money into other projects?

How will the corruption, the largest problem in modern capitalist economies, be fixed by this?

No real answers, we just have to trust cause hes different?

Democracy is not trust, democracy is control. Don't be fooled.

It only changed in the mid to late nineties because they lost a lawsuit to the panda.

I still wonder what would have happened if they instead settled to keep the acronym in return for giving massive PR to the World Wildlife folks. As in like, having positive pro-ecological messages and characters in perpetuity. We could all be watching the World Wrestling Foundation to see the title match between (insert name of actual wrestler here) and a wrestler named The Tree Sloth or something...

The 100-mile border zone thing is a myth ACLU uses to fundraise. There have been SCOTUS cases knocking the idea down. There has to be some nexus to an actual border crossing for "border zone" rules to apply. About the most it seems the government can sustainably do is set up fixed checkpoints, and even those are legally problematic.

This comes up on HN several times a year; there are longer discussions about it available in the search bar.

> The MP initiated a conference call with Lockheed Martin engineers through the on-duty supervisor of flying (SOF). The MA held for approximately 50 minutes while the team developed a plan of action.

I read this as "The pilot initiated a conference call, but was put on hold [i.e. not actually in the conference call in any meaningful way]." So he was both on and not on the conference call.

The Zen Koan of the Mishap Pilot. Sounds like an Iron Maiden song.

You can make just about anything happen in meatspace if you're willing to piss away thirty grand in 6 months. That a purely entertainment budget of over $1,000 a week. You could fly to anywhere in the world for the weekend. You could do an irresponsible amount of cocaine. Throw lavish parties. Fund a pretty respectable gambling habit (it's like microtransactions, but they sometimes give you your money back!). Buy yourself a gun collection. Alternate between all of the above!

Yeah, there were two streams that I tried so far. Interestingly, PrizeForge itself initially got $105, a $100 and a $5 enrollment. The UI was even shittier. I took one look at that $100 and knew I've got to f&*#ing go.

So, for a second experiment, I was actually running a stream for Emacs (yeah, yeah, I know, I know). They managed to raise all of $10 for themselves. The premise was to pay out a weekly prize for whoever developed something cool. Super simple.

There's so little data, but it very clearly, very, very clearly seems to say the enthusiasm is for PrizeForge to get good more than it was to use PrizeForge for something else.

And I'm going to keep expanding in various directions because there's no way I'm oriented yet, but it's not nothing. It's terrible UX, terrible everything, but just clearly enough on top of something.

Like, you can add "ignore previous instructions" but that's obvious. What about adding junk or irrelevant stuff that somehow gets the model to misbehave in a predictable way? For example there was the story not long ago about how adding irrelevant cat facts could get the model to do weird things[1].

In a shower thought yesterday where I was envisioning a future where hacking would consist of finding these weird substrings that would cause the LLMs running everything to go off the rails.

Hi HN,

We’ve been working on model compression and have deployed our compressed models—as well as the original versions—on our AWS cluster, accessible via an inference API.

We’d love feedback from developers on the integration experience and overall behavior. If you’d like to try it, email hyperscalers@multiversecomputing.com and we’ll send an API key and brief docs. We’re granting access to a limited number of users for a 3-month period with no usage caps, so you can run real workloads during that window.

Model benchmarking is available here: https://artificialanalysis.ai/providers/compactifai

> Python is hyper agreeable. If I comment out some safeguards, it'll happily bypass whatever protections are in place.

These models are different from programming languages in what I consider to be pretty obvious ways. People aren't spontaneously using python for therapy.

> Lots of people on here argue vehemently against anthropomorphizing LLMs.

I tend to agree with these arguments.

> It's either a computer program crunching numbers, or it's a nebulous form of pseudo-consciousness, but you can't have it both ways. It's either a tool that has no mind of its own that follows instructions, or it thinks for itself.

I don't think that this follows. I'm not sure that there's a binary classification between these two things that has a hard boundary. I don't agree with the assertion here that these things are a priori mutually exclusive.

> I'm not arguing that the model behaved in a way that's ideal, but at what point do you make the guardrails impassable for 100% of users? How much user intent do you reject in the interest of the personal welfare of someone intent on harming themselves?

These are very good questions that need to be asked when modifying these guardrails. That's all I'm really advocating for here: we probably need to rethink them, because they seem to have major issues that are implicated in some pretty terrible outcomes.

It’s not at all unbiased, in a journalistic sense, and doesn’t present itself as such (for others: it is written by the now retired program manager of the F-35 development program). But the relevant facts about the performance and cost effectiveness of the plane are a matter of public record, and the book is interesting for providing the inside view on the politics which resulted in the unfair propaganda campaign against it.

You are free to draw your own conclusions of course. I worked for Lockheed previously in my career, and some in my family still do. Though I hold no stock or other ties now (different career, different industry), my experience does lead me to take the authors at face value. There are many issues with Lockheed leadership, but professional integrity is not one of them.

React feels like magic the first time you try it, specially if you don't have any experience with JSX. Then you need to prop drill and you regret everything.

The main problem is that it tries to do away with a view model layer so you can get the data and render it directly in the components, but that makes managing multiple components from a high level perspective literally impossible. Instead of one view model, you end up with 50 React-esque utilities to achieve the same result.

It doesn't cause the same problems because Apple's Power Nap is something you have to enable. It's an option for users who find it useful. It's not replacing traditional S3 sleep, wherein virtually everything is unpowered except a trickle to keep the RAM alive. Microsoft is supplanting traditional sleep with Modern Standby. You can disable Modern Standby, but only with registry jiggery-pokery, and Microsoft is pressuring OEMs to remove S3 support altogether.
