Tesla is, in theory, deploying a handful of 1.2MW charger sites: https://electrek.co/2026/02/24/tesla-megacharger-64-location...

Assuming some amount of tesla over-hyping there, Tellus is doing 600kW chargers: https://chargedevs.com/features/inside-tellus-powers-600-kw-...

So _if_ your route had those, you could charge in somewhere around 1.25h. Not enough for break time, but you can imagine starting with, say, a 1.1MWh battery with one +500kWH boost mid-day being enough to get you to an overnight full recharge. Lots of "ifs" there, since you might not always be able to get full charge rate from the charger, might not time things perfectly, etc., but it doesn't seem completely out of scope for a few years from now.

(And who knows, perhaps tesla will come through with those megachargers. Seems more likely than, say, building an autonomous humanoid robot.)

I live in Santa Clara where the first chip fans in the world existed. In places like Santa Clara (home to Intel, AMD, Nvidia), and neighboring Sunnyvale and Mountain View there are maps of chemical leakage of industrial solvents which had contaminated the groundwater.

The very first Google offices sat directly over one of these sites around 2004. It took decades to dissipate. People complained about noxious fumes and this was more than 20 years after the spills had occurred.

There are real tradeoffs to having heavy industry to human health and well being.

Reading this was.. interesting. Since 2008, the CPJ has published the Global Impunity Index, which tracks countries in which journalists are murdered and the killers are not prosecuted. Until 2025 that is, the year when Israel would finally top the index. In fact, the way the index is tabulated, with numbers rolling over the next year, Israel's actions would have likely secured their place in the podium for the next decade. Allegedly according to whistleblowers, the CPJ's donors were unhappy about this. The CEO, Jodie Ginsberg had a rather elegant solution - scrap the index entirely, claiming that they needed to revamp their approach.

" Building an EV requires metal forging, battery manufacturing, painting, and chip fabrication — all processes that drove Tesla to build in Nevada and Texas.
Tesla's Fremont factory was the former NUMMI plant (GM/Toyota, operating since 1962). It was grandfathered in."

This website misses talking about all the Tesla Fremont paint shop violations (see https://www.baaqmd.gov/en/news-and-events/page-resources/202... ) and various OSHA violations:

It's not stockholm syndrome for a lot of people. Microsoft is so firmly entrenched in so much of the corporate world that you can't get away from them. My mom was in the market for a new laptop recently, and I so badly wanted to get her setup with a MacBook Air, but it's not an option because the Sage accounting software she uses for my dad's business is Windows only. And furthermore, the business itself (a small pawn shop) is forced to use some specific software to manage inventory (I believe it allows police to access the database to track serial numbers in finding stolen goods or something), which is a webapp using some antiquated decades-old technology that only runs in Microsoft Edge's IE-compatibility mode (which has become a more and more difficult incantation to enable over the years) and I believe that can only be used on the Windows version of Edge.

For me it's currently the most hassle-free way to make my Steam library runnable. But it feels like we're moving in a good direction thanks to Valve's efforts where one day I may be able to never boot into Windows on my PC.

> If I had a button that would wipe out the entire Amazon jungle and replace it with a world class high technology industry, I wouldn't even think twice before pressing it.

I used to think this way, but I've come to realize that it's very short-sighted. It's not sustainable, and we're already seeing how unchecked industrialization over the last couple centuries is leading to unintended/undesirable effects on our health, and indeed the suitability of the environment we need to live in. Sure, those problems can be pushed onto future generations, and so far (maybe) we've been able to solve them. But if we care at all about humanity's ability to thrive, we need to be more careful.

In developed countries, nobody has to struggle anymore just to stay alive, which is a far cry from the way it was 200 years ago. Advancements now are along the lines of increasing entertainment, or quality of life. But enjoying a good life doesn't have to be a zero-sum proposition, and I think society should put a higher cost on the ability of wealthy people to use up irreplaceable natural resources for their own benefit.

I also had unsolicited spam from Vincent Jiang of Aden, another YC company.

Hi Daniel,

I just came across your profile on social media and wondered if you'd be interested in joining our Discord community for AI agent development. Currently, we see that agents break, loop, get lost, hallucinate, and cost a fortune, and therefore built a space where developers can share challenges and insights.

This is IMO one of the coolest tech stories to ever happen, but I haven't been keeping up with new developments from this story since it broke. Last I heard, the best guess at what happened was some state-sponsored actor worked very hard to get this merged, and it was caught luckily at the last minute. But no one had any smoking gun as to who did it or why or who they were targeting. Any new developments since then?

If you're going to go pre-20th century, Russia has the dubious distinction of having waged the most "total" recorded genocide in history, the Circassian genocide.

Just because you haven't heard of Russia colonizing doesn't mean it didn't happen just as much. It just wasn't where the other imperial empires were. How else would one city come to a rule a continent-sized territory? A big difference is, they didn't keep records of such things.

There is no need to give it for free. It costs very little to produce. Just sell it over the counter at walmart for $5 just like they do rat poison, bottles of vodka, and ammunition.

You might say they won't be able to sell enough foodstamps or welfare even then to come up with the money legally, but it'd still be way less crime.

It seems that you're framing it as if regulation is some random burden that appeared out of nowhere rather than a defence mechanism that emerged because businesses repeatedly abused workers, cut corners, and pushed costs onto everyone else whenever they were allowed to.

Work, technology, supply chains, data, health and safety, and the whole economy are all far more complex than they were in the 90s, of course regulation increased: we had to adjust to respond to the new challenges and everything else. It increased because the damage companies can do increased significantly too (we are literally discussing about existential threats to humanity and life on earth in the last few years), and because we learned again and again what happens when you leave everything to "the market" and trust firms to self-police.

Also, this idea that gig work is some balanced freedom on both sides sounds nice in theory but falls apart in practice. I'd go as far as saying that it's naive. The company/platform keeps the power, sets the terms, and the worker carries the instability and everything that derives from that. "You can sign up to multiple apps" is not a real solution to insecure income, it's just telling people to juggle several unreliable income streams at once and hope enough scraps appear each week. And whereas for businesses "losing" means lower profits or no profits (with the worst case scenario being that they have to shut down), for workers this can mean huge financial insecurity, depression, lack of control, and potential destitution. I'd say the latter is markedly more dramatic.

Put differently, it's not meaningful flexibility for most people, more like risk transfer. The business gets labour on demand without commitment, while the worker still has rent, bills, and food costs arriving on a fixed schedule and with the threat of actual death if they end up homeless in the winter.

And on the "hiring risk" point: why should that risk be shifted onto workers, who have far less power, money, and protection than firms? If a company depends on labour to function, employing people properly is not some unfair punishment - it's part of the cost of doing business in a civilised society. The only reason private enterprise is tolerated at all is that it is supposed to produce a social benefit. If a business model only works by making workers permanently disposable and pushing insecurity onto society, then that is a criticism of the business model, not of regulation. And it's probably not worth keeping the private sector either.

That's a lot of incompatibilities.

LLMs like to use the shell because it's stable and virtually unchanged for decades.

It doesn't need to worry much about versions or whether something is supported or not, it can just assume it is.

Re-implementing bash is a herculean effort. I wish good luck.

I suspect that this categorization is a result of confusion on the part of law enforcement and their inability to cope with the post-ideological landscape of the internet. Someone who believes all manner of contradictory things is not a “nihilist,” they just have an unsettled or dynamic belief structure. This may be because they haven’t fully worked out their beliefs, or it may be because they are willing to readily adopt new beliefs if they seem advantageous. In essence this seems more Discordian than nihilist.

There’s also a third option, the person doesn’t see a problem with superficially adopting other beliefs as a form of camouflage, but they do have a core set of beliefs.

In general I think the chaos of the internet and the exposure to multiple points of view encourages fragmentation and dynamic systems of belief. I don’t necessarily see it as a bad thing, either.

> Where do you find clean water to fill the pool with?

The Earth is literally surrounded by water. I'm sure people will find a way. Treat the water if needed.

> if you pay them enough to be middle class, your product's price stops being competitive

Tell that to China's growing middle class, not me. We have western corporations shitting all over western values and culture and kowtowing before China and their censorship because they can't afford to lose the chinese market. That's where money is flowing now. It's one of the reasons why Trump wants to weaken the US dollar.

Nope. And I can tell you why.

Because which employer we work for is voluntary. If I own a business, I can choose which systems I implement in order to ensure a certain level of quality. If I had a logistics company, would it be inhumane to install cameras in the truck and GPS devices that monitor speed? Absolutely not. There's something called "risk" and from a business standpoint, it needs to be mitigated and controlled.

That is why, as employees, even certain key words are monitored on our computers. If we're in a relationship with a co-worker, it needs to get reported. The list goes on.

A critical part of fast food is customer service. If customer services goes down the drain, that presents a very real business risk to Burger King.

To a certain extent, this has been a standard practice in the field of customer service representatives that are taking calls all day. Their calls are monitored and recorded, then reviewed to ensure a certain level of performance.

"Instead, employers will likely increase their reliance on temporary workers with fixed-term contracts"

It's no quick fix. The new six month (previously two year) unfair dismissal rules from January 2027 already impact annual fixed term contracts. As the end of a fixed term contract is legally a "dismissal", it'll be necessary to go through the full process.

I suspect some low-level service industry employers will sense the weakness of the jobs market and increase employee turnover by giving people contracts of under six months then rinse and repeat from the queue of applicants, which would suck for someone who wants a temporary job for a year or two like students.

Netscape had a 90% market share in 1995. If OpenAI is metaphorically netscape, what prevents its competitors from prying away customers every day? What prevents google/facebook/microsoft from using their position to bundle chat experiences? Especially if the tech is a commodity and OpenAI's models are about as good as everyone elses?

You're configuring something that costs money (electricity, hardware, real estate) to provide. Either it's "pay as you go" or you have a flat rate and a cap.

If you have a cap and then your thing hits the front page and suddenly has 10000% more legitimate traffic than usual, and you want the legitimate traffic, they're going to get an error page instead of what you want. If there is no cap, you're going to get a large bill. People hate both of those things and will complain regardless of which one actually happens.

The main thing Google is screwing up here is not giving you the choice between them.

Apple has offered products with little value over competitors for a long time now, but they still get to command a large premium on their products because "the vibes are right".

When engineers analyze things they look at the specs, stats, and metrics. When consumers analyze things they look at what others are doing, feel for vibes, roll into the convenience, and stick with the familiar.

Author here.

MVAR is an IFC-based reference monitor for AI agent runtimes. Rather than attempting to detect prompt injection at the model layer, it enforces deterministic policy at privileged execution sinks.

Core invariant:

UNTRUSTED + CRITICAL → BLOCK

All data carries integrity and confidentiality labels with conservative propagation. Policy decisions depend on provenance and sink classification, not payload inspection or intent scoring.

Enforcement is structural rather than content-aware. MVAR does not parse prompts or evaluate semantics; it evaluates data lineage flowing into privileged sinks.

The goal is impact reduction: preventing untrusted-derived outputs from triggering unsafe tool execution.

Phase 1 scope and known limitations are documented in THREAT_MODEL.md (manual sink registration, no composition attack modeling yet, etc.).

Reproduce locally:
./scripts/launch-gate.sh

Happy to answer technical questions and welcome adversarial feedback.

I would like to restrict the term "Public keys" to refer to asymmetric encryption keys which can be made public without compromising security.

The only purpose of the keys Maps/Stripe encourage you to publicly put into your website is to guarantee it is talking to _your_ Google/Stripe account not someone else's. Obviously once you put them in your client they are of zero value in helping Google/Stripe identify you. The fact that Google allows you to use the same type of key they also use elsewhere to identify _you_ not _them_ was always incredibly bad design. Google already have the 'Project ID' which would have been the best thing to use.

Unfortunately the paper is riddled with errors, both in the concepts and in the examples.
Just a few to mention:
- The segment search algorithm in listing 5 is wrong, since it mistakes the usable range for the currently used range
- The binary search algorithm in listing 6 (something very basic) is totally wrong
- The delete method is incompatible with the binary search. Take as an example the data set in Fig. 3(a), where a search for number '6' would miserably fail, due to deletion and the 'VOID' marker used.
- Some running times are badly estimated, even if it was to work (without any deletion on data, which breaks it)

Nice try, maybe could be reworked to be usable (which is not).

On the web app, I see the "temporary chat" option but no toggle. It tells me temporary chats aren't used for model training. I thought I remembered that chats of Pro customers aren't used for that in any case. Hard to keep track of all this stuff.

Ultimately, I think the crossover memory is useful, but I'd really like to know exactly what's in there and an ability to validate/adjust, not just on/off.

For largely unskilled service sector jobs, where one might consider the worker relatively interchangeable, it is particularly bad if your government also has an "infinite immigration" policy in practice.[1]

It actually can since its just symmetric encryption. Any key holder could decrypt the payload. In fact, the channel could simply be the shared secret.

Let's say we have 10 people in a call, 5 share a key and the other 5 share a different key. Without the shared key audio simply will not decrypt. You could have two private channels with one host.

thats a strange statement. its certainly not black and white, but the compiler has explicit lifetime information, while the cache infrastructure is using heuristics. I worked on a project which supported region tags in the cache for compiler-directed allocation and it showed some decent gains (in simulation).

I guess this is one place where it seems possible to allow for compiler annotations without disabling the default heuristics so you could maybe get the best of both.

That, and you have to ensure your energy costs (power) are low and you have a secure source of raw materials. I'm not an expert, but from what I've heard, the economic region over there has been doing a poor job on both those fronts. Furthermore, you have to talk about regulation vs safety. The EU has regulation. Maybe too much.

There are also network effects. Your plant that is energy intensive is closing? Now other manufactures must increase their cost as transportation is increased and local contracts harder to get. Your chemical plant, which has operated within good bounds for a decade can't get a permit to expand, or is protested? Your intake products now either go up in price or become unable to attain them at all.

Hi HN,

I wanted to share something I’ve been building called Spana Time (https://spanatime.com). It’s an AI-powered conversational commerce platform that handles everything in the automotive ecosystem—dispatching mechanics, sourcing spare parts, towing, and rentals—entirely through WhatsApp. We are currently operating in Uganda.

The Problem
The automotive repair and parts industry here (and in many emerging markets) is deeply fragmented. When your car breaks down or you need a specific part, the last thing you want to do is download a new, single-use app, fill out complex forms, or drive around to five different shops to compare prices. Furthermore, the industry suffers from a massive "trust gap"—it’s incredibly hard to know if you're getting a fair price or a reliable mechanic when you are stranded.

How it Works
Instead of forcing users into a native app, we built the entire pipeline on top of WhatsApp, which is already installed on almost every smartphone here.

Intent Extraction: A user texts our bot a problem (e.g., "My car stalled, need a tow" or a photo of a broken brake caliper). The AI parses the intent, extracts vehicle details, and identifies parts.

Geospatial Broadcasting: It then pings verified local mechanics, tow trucks, or parts shops within a specific GPS radius of the user.

Bidding/Quoting: The providers receive the lead and reply with their price. The user gets a list of options right in the chat and picks the best one.

Solving the Trust Issue
The biggest thing I noticed while building this is that standard 5-star rating systems are practically useless for weeding out bad mechanics; they are too easily gamed.

To solve this, we built a trust engine that goes deeper than just aggregate stars. The system analyzes the actual sentiment of post-job written reviews to calculate a dynamic trust score for each provider. We also generate automated weekly performance reports for the mechanics, showing them their job completion rates and customer feedback highlights. If a provider's trust score drops too low, the system automatically stops broadcasting leads to them. This ensures that genuinely top-tier mechanics are rewarded with the most work, rather than just whoever has the biggest marketing budget.

I’d love for you to poke around the site (you can see live examples of the chat scenarios on the landing page). I'd deeply appreciate any feedback on the concept, the onboarding flow, or the approach to parsing conversational intent for physical services without forcing an app download.

I'll be hanging out in the comments to answer any questions!

As I said, I argue for some earned income tax. I'm a proponent of a progressive earned income tax as a way of reinforcing the social contract: we all contribute, we all benefit.

No one tax "solves" the problem. The problem, as I see it, is wealth hoarding beyond what any normal person would need to carry them through to the end of life. Instead of listing everything we should tax, maybe it'd be shorter to say that we look at what billionaires do to avoid taxes and close those loopholes. Then watching them again, and every time they come up with a new tax evasion strategy, fix it.

I wish I had the resources to develop an AI system that could find and document all instances of tax evasion by billionaires. But if I did that, I suspect I would need to be extra careful crossing streets, going near balconies, and reminding people that I'm not suicidal.
