>>Bro as a kid I used to go to church every Sunday

I mean, not to dismiss your experience, but in my weekly Sunday going to church in Poland the priest would write an actual homily that felt relevant to the community. But then our small town had 3 churches, and each one had a different style - people would talk about preferring one over the other because they had more interesting "content".

But yeah, there was the message from the regional Bishop or the Archbishop of Poland or sometimes directly from the Vatican, then the reading from the old testament, then the homily which I'm 99% was written by the priest giving the mass.

>> I guarantee that not a single person from my entire village understood what the priest was saying

Well, I wouldn't say not a single person did, but yeah, we had those 3 churches, probably 10k seats each, every one was rammed on the sunday, but I'd say 90% of people there were only there to tick it off and snoozed through the whole thing. But it's not because the homily was boring, it's because going to church on sunday was(maybe still is?) a thing you have to do or people will make fun out of you.

Do you not do stops? The ranges I've shown include a 15min stop to recharge.

The ranges you showed were inaccurate, for the reasons I cited, including 22 minutes to charge under only special circumstances, with super special very rare chargers.

When I stop to refuel a car, I put fuel in and drive through. I urinate often on the side of the road, or (what takes 2 minutes) while the car pump runs.

Driving 1600km is under 12 hours driving, including those stops. No I'm not tired or lacking in focus at the end of that time. It's only 12 hours.

You'd need to recharge three times time make that range, or 22 minutes * 3 plus the fact (which you are ignoring) that you can't drive where ever you want and get that speed of charging. No way.

If you think driving for a few hours is dangerous, you are completely out of it.

This is the problem with these discussions. People sugar coat all the issues, and pretend they don't exist.

And this isn't even a conversation about "use fossil fuels". Oh no. This is "you'd better use MY green tech, or you're nuts! and I don't want you to even try another tech, how dare you!"

The more options we have, the better.

There are already very good sub-$100 lidars, especially for 2D since they were made en masse for vacuum cleaners. E.g. the LD19 or STL-19P as they're calling it now for some reason. You need to pair them with serious compute to run AMCL with them, plus actuation (though ST3215s are cheap and easy to integrate now too) and control for that actuation which also wants its own compute, plus a battery, etc. the costs quickly add up. Robotics is expensive regardless of how cheap components get.

Are they though? Another comment (https://news.ycombinator.com/item?id=47116205) seems to indicate these people are all indefinitely suspended with no path to unsuspend them:

You've been told why that time is longer than you think, and why it hurts long distance travel. Ignoring that in your reply isn't helpful.

This conversation is about R&D too. Batteries used to take forever to charge. They're better than they were. But I guess h2 can never improve, ever? And all these made up "hassles", oh no, you have to plug the nozzle in right? How tiresome! And I guess they can't insulate the handle? And the speed, well it takes hours to pump? All made up problems.

In principle, as the sibling comment says, you could measure just the phase difference on the receiver end. The trick is that it's much harder for light frequencies than radar. I'm non even sure we can measure the phase etc of a light beam, and if we could, the Nyquist frequency is incredibly high - 2x frequency takes us to PHz frequencies.

There might be something cute you can do with interference patterns but no idea about that. We do sort of similar things with astronomic observations.

It doesn't surprise me it happens within the Elsevier ecosystem.
Elsevier has a long tradition of scientific misconduct and scientifically immoral behavior (see Wikipedia).

The operating margin of Elsevier is around 40% which is huge! At the end mostly paid by tax-payer money.

Personally, I never review or publish with Elsevier.

> We understand that a subset of these users were not aware that this was against our ToS and will get a path for them to come back on but we have limited capacity and want to be fair to our actual users.

It feels like a good default for this would be something similar to video game bans: where you get a "vacation" from the service with a clear reason for why that is, but can return to using it later. Given how much people depend on cloud services, permanent bans for what could be honest mistakes or not knowing stuff would be insane.

> Tesla are producing cyber cabs now which are 10th the price of Waymo's and can drive autonomously anywhere in the world.

Wait what? when did they actually enter mass production?

> I mean humans have Lidar sensors

Real time slam is actually pretty good, the hard part is reliable object detection using just vision. Tesla's forward facing cameras are effectively monocular, which means that its much much harder to get depth (its not impossible but moving objects are much more difficult to observe if you only have cameras aligned on the same plane with no real parallax)

Ultimately Musk is right, you probably don't need lidar to drive safely. but its far more simple and easier to do if you have Lidar. Its also safer. Musk said "lidars are a crutch", not because he is some sort of genius, Its obvious that SLAM only driving is the way forward since the mid 00's (of not earlier). The reason he said it is because he thought he could save money not having lidar. The problem for him is that he didn't do the research to see how far away proper machine perception is to account for the last 1% in accuracy needed to make vision only safe and reliable.

that's a good point - the reformulation from AI tools is as you say "eroding the teeth" of the GPL based solutions - but the cost to make these solutions is dramatically reduced.

I'd even go further and say that the biggest problem of free software has always been the lack of frontend/designer willing to put in the contributions to make the UX a pleasant experience.

I guess we could argue that with the frontend skills of recent models it's also getting better.

Now the question will be after all that how much we will be willing to pay for a slightly better integrated experience ?

Waymos are still making lots of errors that a human wouldn't (Stopping in middle of a road due to a puddle was a recent one https://dmnews.co.uk/waymo-robotaxi-spotted-unable-to-cross-...) 17 years after betting on LIDAR, I think Tesla is ahead now in most respects. It's could be wrong though we will probably know by the end of this year.

We keep theorizing about AGI governance.Nobody is running agent Darwinism experiments.
Don’t speculate.Run the experiment.
Instead of writing essays about future agent civilizations,why not build a controlled arena and let them compete?
What do they actually compete for?
What becomes scarce?
What strategies dominate?
How do they define value?
What does “survival” mean to an agent?
If anyone here is interested in co-designing or participating in an agent arena experiment, reply below.Let’s test evolution instead of narrating it.

The beam is split and re-emitted in multiple points. By controlling the optical length (refractive index, or just the length of the waveguide by using optical junctions) of the path that leads to each emitter, the phase can be adjusted.

In practice, this can be done with phase change materials (heat/cool materials to change their index), or micro ring resonators (to divert light from one wave guide to another).

The beam then self-interferes, and the resulting interference pattern (constructive/destructive depending on the direction) are used to modulate the beam orientation.

You are right that a single source is needed, though I imagine that you can also use a laser source and shine it at another "pumped" material to have it emit more coherent light.

I've been thinking about possible use-cases for this technology besides LIDAR,. Point to point laser communication could be an interesting application: satellite-to-satellite communication, or drone-to-drone in high-EMI settings (battlefield with jammers). This would make mounting laser designators on small drones a lot easier. Here you go, free startup ideas ;)

This comes up here and there to discredit the developer but having followed all the drama for many years now I just want to add that Dansup has apologized multiple times, and has been far more open about his process. His communication has also changed for the better over the last two years especially. Its not easy being human, and I think its a good sign to see that he takes this seriously.

When I started my company, Tippel.ai, I needed a simple website.

Agencies quoted me around €1,500 and nearly three months for a basic setup. That felt unreasonable—so I decided to build my own solution.

Over the next few months, I created a system that turns a short configuration form into a fully deployed, production-ready website. It includes hosting, SSL, mobile optimization, and basic SEO—everything you need to get online quickly.

That system became PromptPageAI.

With PromptPageAI, I built https://tippel.ai
myself—no agency, no long development cycles.

PromptPageAI is built for founders, small teams, and even local businesses who want a professional website without dealing with infrastructure, templates, or complicated CMS setups.

If this sounds like a problem you’ve faced, I’d love to hear your feedback.

There is no face. The depictions of God the Father are relatively new (in the history of the church; it's still Renaissance). Some people used to have problem with them (Jesus can be depicted, as he was a man, but can be Father?) but then it calmed down.

If people think it's literally a face in the sky, they are probably mentally challenged.

It's fair to point out that comma.ai is SAE level two system, however it's not geofenced at all, which is an SAE level 5 requirement. But really that brings up the fact that SAE's levels aren't the right ones, merely the ones they chose to define since they're the standards body. A better set of levels are the seven I go into more detail about on my blog.

As far as distinguishing shadows on the road, that's what radar is for. Shadows on the road as seen by the vision system don't show up on radar as something the vehicle will run into.

Predictable if you follow the economics.

The scaling thesis behind all this buildout is looking shaky (to say the least), smaller models keep closing the gap on the big ones. Meanwhile voters are watching their electricity bills go up and blaming whoever approved the permits.

Great idea, keyboards on phones are pretty bad, though a bit ironic to have a taller keyboard with the message about not eating pixels

Also it's missing alternative symbols that you could get by holding a key, so for example, inserting a single number or a quote isn't convenient. And it's missing all the other ergonomic gesture advantages of hold+move gestures

The video is also misleading, there are no gaps between keys in regular keyboards, that's just visual effect that doesn't affect anything. And the qwerty jamming reason is a myth (though not 100% certain)

And why no iOS, the hex keyboard Typewise exists there, why did this project got blocked?

> The heavy use of shell scripts for instance in this post here...

There's exactly one in the post. It's ten non-blank/non-comment lines, and the author says of it

This is not well designed but it gets the job done.

My least favorite thing to see in the world is a Ruby, (worse) Python, or (much worse) Go program that could have been a very simple shell script.

When my sysadmin programs get more complicated, I reach for something more suited (like Erlang), but if the shell script is simple and only has deps on other standalone programs, then I write a shell program.

First of all, nice idea and good execution!

The problem is WARN only fires when companies actually fire people. AI displacement doesn't really work that way, at least not yet. Customer support new hires dropped 65% in eight quarters (https://www.saastr.com/customer-support-hiring-has-fallen-65...).

The trend is to include as much as the aircraft’s capabilities in the checkride now.

For an IFR checkride, if you do it in an aircraft equipped with autopilot, at least one approach will have to be flown with the autopilot.

Not sure if that’s made it’s way to the PPL checkride (or been codified) but it’s inevitable.

Right, that's why they have massive churches adorned with gold and intricate sculptures. Just because it technically isn't required to pay does not mean that years of brainwashing won't condition you to give your money away. I've only been a few times, but seeing old people queue up to give a sizable part of their pension to the church just made me sad.

Misses a few interesting early models: GPT-J (by Eleuther, using gpt2 arch) was the first-ish model runnable on consumer hardware. I actually had a thing running for a while in prod with real users on this. And GPT-NeoX was their attempt to scale to gpt3 levels. It was 20b and was maybe the first glimpse that local models might someday be usable (although local at the time was questionable, quantisation wasn't as widely used, etc).

As a massive hedge fund with insane holdings managed by complex legal nuances & historical treaties, juggling critically withheld information, and having an outsize political presence as an independent state (thanks Benito Mussolini!), The Vatican has great financial incentive to have smart quants, historians, lawyers, and others on the payroll.

Based on their balance sheets I think they get it very, very, well.

Steve Jobs took a vow of poverty at Apple, too… somehow, some way, the dividends and stocks and private planes and fancy business dinners and everyone kissing his ass made a $1 salary survivable. Poor guy.

The vite plus idea is that you'll pay for visual tools. What's odd to me is it makes their paid product kind of a bet against their open product. If their open platform were as powerful as it should be, it would be easy to use it to recreate the kinds of experiences they propose to sell.

The paradox gains another layer when you consider that their whole mission is to build tools for the JavaScript ecosystem, yet by moving to Rust they are betting that JS-the-language is so broken that it cannot even host its own tools. And because JS is still a stronger language for building UIs in than Rust, their business strategy now makes them hard-committed to their bet that JS tools in JS are a dead end.

Why do most people need large language models?

And as far as I understand, the main contingent of HN is engineers, programmers, and even me, who works in a country (Russia) where the salary of an engineer is just tiny compared to Europe or the United States, it was not difficult to buy powerful enough equipment to run most large local models, train lora, then programmers who earn income in six-digit dollars it's even easier to do this.

The optics are bad. Sam needs a good PR firm/coach. He also needs a Sheryl Sandberg in my opinion.

The message behind it is that yes, training a new model uses a lot of energy but the benefits are enormous once trained. I think his humans use energy too analogy likely came from him hearing messages about how training pollutes the earth. In his mind, he thinks training a new model is as useful or more useful than 3,000 people on average. Even if he is right, he shouldn't have used this analogy due to how sensitive people are right now with AI, energy, potential job loss, etc.

Parameterized queries fail to protect from SQL injection for decades, because database engine developers fail to listen. What could work instead, if any parameter could be safely injected:

SELECT $1, $2($3) FROM $4
WHERE $5 $6 $7
ORDER BY $8 $9
GROUP BY $1

but at that point SQL loses its point and turns into MongoDB query language.

Probably none.

I grew up in Mexico--spending a few years in or near Puerto Vallarta, specifically, funnily enough--and the M.O. of the cartel is overwhelmingly geared towards keeping a VERY low profile. Their whole purpose is to be quiet and subtle.

For every "loud" cartel action in MX, there are twenty that you never see, and then ten that exist as different recyclings and exaggerations and attack ads in the US to (now) perpetuate the current administration's favorite scapegoat, or (then) to prevent people from emigrating from the US.

It's been like that since '07 or so: take a story from Ciudad Juárez or Tamaulipas, then magnify it and convince Americans that the entire country is like that, so that they don't pay attention to the fact that they could get cheaper healthcare, out of pocket, by driving across the border to an equally well-equipped hospital... than they would for the cost of a single ambulance ride in the States... while living in a house that cost 10-100 times more than a house of the same size and quality across the border. All the while, the cartel hums happily along, truly wanting absolutely nothing to do with you.

Fear sells, and fear controls. Just like whatever series of headlines got you wanting to believe that they've infiltrated the American govt. ;)

> only for it to go over the heads

If it actually went over their heads, then the effort was wasted. I've heard hte goal of preaching described thus: "Address the mind to move the heart to change the will." If you haven't addressed the minds of the people you're speaking to, your preaching was a failure.

NB if the people in the parish don't want to change their will, and so close up their minds, that's a different issue.
Show HN: Implementing ping from the Ethernet layer (ARP,IPv4,ICMP in user space)
by ibuki256 | 2026-02-23 09:41:30+00:00
I built a user-space implementation of ping that constructs Ethernet frames, performs ARP resolution, builds IPv4 headers, and sends ICMP echo requests manually using AF_PACKET.

- ARP (packet format, cache with aging, re-ARP, conflict handling)
- IPv4 header construction and checksum
- DF handling and ICMP Fragmentation Needed (Type 3 Code 4)
- IP fragment reassembly
- ICMP echo request/reply parsing
- A basic ping loop with loss statistics

The goal was to understand how packets actually move from Layer 2 upward.

Humans cannot drive safely. Human drivers kill someone every 26 seconds. Waymos have never killed a person.

Part of that is that humans are distractible, and their performance can be degraded in many ways, and that silicon thinks faster than meat.

But part of it is the sensor suite. Look at Waymo vs Tesla robotaxi accident rates.

A healthy relationship with technology isn't the same as not using technology.

> It doesnt seem like any of this would really be useful as you'd have to enter all the useful data manually(calendar).

You have to enter calendar data somewhere, right now I often have the same info or different subset split between my calendar, work ones, my wifes one and the one on the wall. Even the paper version requires having entered the data - more so than the tech based ones because an invitation sent by email now needs to be manually copied over. Or have I misunderstood?

> You dont need real time information because you know how long it takes since you've done it 1000s of times and it beeps. All these things are just managed in our heads subconsciously.

This seems odd to me. First just a couple of things

> You dont need real time information because you know how long it takes

1. It takes different amounts of time depending on the load and settings

2. Knowing how long it takes and when to take it out is something the person who put it on knows, but there are different people in this house who can all do either task

3. It's in a place where the beeping is often not heard

But more interestingly is that we're comparing two different approaches. One is

* A note written in a place that washing needs to be taken out if it's not been done.

You describe this as an unhealthy relationship with technology.

Your better solution is

* Work out when a machine will finish its task, remember this

* Wait for the machine to shout at you

* If you don't hear it shouting then keep checking the time to see if it's finished its task

* Make sure you track all of this in your head on top of anything else

This is more healthy? Than a note on the wall that says "change the washing"?

Imagine you started with the typical thing being that you have a note on the wall that says "washing is done" when it's done and the machine itself is silent. I come along and tell you I've got a much better, healthier way of interacting with it - wait for it to make an annoying noise!
