> I'm not against constructive criticism of Waymo.

I feel like you have to say this out loud because many people in these discussions don't share this view. Billion dollar corporate experiments conducted in public are sacrosanct for some reason.

> I just think it's important to consider the counterfactual

More than 50% of roadway fatalities involve drugs or alcohol. If you want to spend your efforts improving safety _anywhere_ it's right here. Self driving cars do not stand a chance of improving outcomes as much as sensible policy does. Europe leads the US here by a wide margin.

Makes you wonder. Technology usually becomes less expensive. Car companies have used it as a differentiator for years though. There are giant cost differences between like a base line Tundra and a top of the line and the mechanicals are the same; it's more price for luxury and more tech.

Seems like Toyota is about to make a big Lexus pivot in the next year or two.

> Yes, and that's even more encouraging, that there's still effects of Vitamin D on major depression even if already on antidepressants! This suggests we can "stack" the interventions.

I think the point here is that such a study selects for people where their antidepressants are already known not to work very well for them, or they wouldn't be interested in participating.

SpaceX is rockets, now global satellite internet, ...

To credibly harness off-world resources at any scale, there are going to need to be automated refueling depots and many kinds of robotic automation for resource extraction. With the Asteroid Belt looking amazing for quantity and accessibility of resources.

That would also completely remove the lid on how many $ trillions of market cap SpaceX could accrue.

So I find it ironic that Tesla is moving away from cars as product, and still talking up humanoid robots, which as yet are not a product, and as research don't seem to have an edge on anyone.

ALSO: Data centers on the moon make more sense than data centers in orbit. Obviously where latency isn't king, but compute is. Simple cooling sinks, dense (low local latency) expansion, dense (efficient) maintenance, etc.

We're still figuring out how to detect "silent" failures where the job doesn't crash but stops making progress — like NCCL hangs where ranks are waiting indefinitely, or gradient norm explosions that don't trigger OOM but tank loss. Right now we rely on explicit errors in logs, but curious how others approach detecting "the job is technically running but something is very wrong" (if at all)?

So with 8 customers per box (AMD EPYC™ 9645 CPU has 96 cores) if they have single-cpu boxes, that would need 256 GiB RAM.

CPU launch price 11000 USD.
RAM will likely be another 10000 USD

20000 / 8 customers / 40 USD/mo = 62 months just to recoup CPU and RAM let alone other components.

Weird, whenever I napkin math offers of any HW for renting, I get that I could buy it myself in 1-2 years of rent. Sometimes faster.

Do they not intend to recoup the costs of HW? :)

I'm more and more inclined to suspect that XEverything is some kind of money laundering scam, where the world's richest people throw money at Musk because of his politics - which they hope will make them even more money. And not because of his technological promises, which are increasingly ridiculous and unbelievable based on more than a decade of his own public statements.

Given my personal experience with various BI systems I think an AI agent like this is the perfect use case. These systems are operating on multiple layers of being wrong as is - layer 1 being your query is likely wrong, layer 2 being how you interpret the data is likely wrong.

Mix them together and you’re already deep in make believe land, so letting AI take over step 1 seems like a perfect fit.

I was hoping to read this article and be surprised by how OpenAI was able to solve the reliability problem, but alas.

Generally you’d like the variable to imply a call to action. Even if the call to action is for a feature still in the backlog.

Over time I’ve developed some tricks that invite people to add features to the code in the “right” place, and this is one of them. Once in a while someone gets credit for work I already thought to do but didn’t have time. But for every one of those there’s a half dozen or a dozen cases of increasing the bus number on a block of code I wrote be nerd sniping people into making additions while I’m busy with something else.
Show HN: The Profanity API – Context-aware content moderation
by Olehype | 2026-01-29 19:20:18+00:00
Hi HN, I built this because existing profanity filters are frustrating to work with.

The problem: Most moderation APIs either flag everything with "ass" (including "assistant" and "class") or miss obvious toxic content because they only do keyword matching. They can't tell the difference between "I'll destroy you in this game" (friendly gaming banter) and actual threats.

The Profanity API uses a 5-layer detection pipeline:
- L0: Instant blocklist lookup (~2ms)
- L1: Fuzzy matching for obfuscated text like "f*ck" or "sh1t"
- L2: 768d semantic embeddings to catch meaning, not just words
- L3: Context classification (gaming, professional, child_safe, etc.)
- L4: LLM-powered intent analysis for edge cases

The key insight: layers can disagree. If the blocklist flags "kill" but semantic analysis scores it low in a gaming context, that disagreement triggers LLM analysis. This catches "I'll kill it in the presentation" vs actual concerning content.

Built with Cloudflare Workers, Durable Objects, and Groq's llama-3.1-8b for the LLM layer. Tiered pricing where you only pay for LLM calls when they're actually needed.

Happy to go deep on the detection logic, false positive reduction, or the skip engine that decides which layers to run.

This "Elon Musk lost interest" is very, very naive take.

Actually I think this new directions demonstrates how great decision making they have at Tesla. Today and even more in the future they have no way of competing with the Chinese manufacturers. It is simply physically not possible.

So they are rightfully pivoting and moving away from the race to the bottom that is ensuing.

The only places it does is where humans can't easily go: space, underwater, hazardous industrial sites, etc.

It can occasionally make sense for high skill stuff where the shortage is people who can even do it, like remote surgery.

In your house? That's silly. It'd be 100X more expensive and complicated than just hiring a housekeeper so you could... hire a remote housekeeper?

What do you mean by "without a brain"?

There are multiple examples in the literature of people leading perfectly ordinary lives whilst unknowingly having no more than 5% of the typical amount of brain matter (typically because of hydrocephalus). For example, https://www.science.org/doi/10.1126/science.7434023 from 1980.

> AI SRE in 2026 is what DevOps Anomaly Detection was in 2015 — bold claims backed by huge marketing budgets, but lacking independent verification. There are stories of SaaS vendors abruptly killing the observability stack. Our results mirror ClickHouse’s findings: while LLMs can assist, they lack the capabilities of a skilled SRE.

The key is LLMs can assist. It would be nice if they went farther into this, and seen how much more quickly a human that wrote a complex prompt, or went back and forth with a coding agent, could do the tasks compared to an unassisted human. I'm confident that it's at a level that already has profound implications for SRE. And the current level of getting it right with a simple prompt is still impressive.

To be clear, Neuralink has shown some promising signs. Has also shown some terrible signs.

And then I don't know if Musk is oversimplifying for a soundbite or more of his Dunning Kruger, but some of the descriptions seem to lack any knowledge of neurology. He describes a universal chip that will do different things and solve different issues depending on what part of the brain it's implanted in. That's not how it works at all.

Give me a break. Tesla has 4 different, 4 person cars. It's redundant. In manufacturing and business, reducing variability is everything. Engineering and supply chain has now been freed from two entire SKUs. That's massive. In a self driving world, they don't really the Model 3 either. The best part is no part - well getting rid of two entire vehicles worth of parts that contributed very little to the bottom line is massive.

It's amazing after 20 years of the same MO, people still don't understand how Tesla/SpaceX operate and succeed. It's like deleting millions of lines of code from a code base. It improves not just performance of the organization, but maintenance as well. The S/X were outsized tech debt on every facet of the business and now they're gone. 100% the right move and very few people understand it.

On reddit they used to say "the down vote is not a disagree button" but that's not the case here. I've been specifically corrected when I assumed that.

So if the prevailing opinion is that ice is committing murder, it makes sense a contrary comment would be heavily down voted.

I agree that hn is heavily liberal and holds a lot of the toxic leftist anti-thought patterns that are prevalent on reddit. But I think it's more of a symptom of the country and perhaps the West being wound-up over "things".

> I think the purpose of Genie is to be a video game, but it's a video game for AI researchers developing AIs.

Yeah, I think this is what the person above was saying as well. This is what people at google have said already (a few podcasts on gdm's channel, hosted by Hannah Fry). They have their "agents" play in genie-powered environments. So one system "creates" the environment for the task. Say "place the ball in the basket". Genie creates an env with a ball and a basket, and the other agent learns to wasd its way around, pick up the ball and wasd to the basket, and so on. Pretty powerful combo if you have enough compute to throw at it.

> I am, of course, in no position to question senior dev, but what do you guys think - is it really normal that all the college so called "best practices" go straight to the trash bin or am I just misunderstanding the real-work-like context?

The first thing you should do is to absolutely question your team if you think their ideas aren't good and have better suggestions.

Also stop looking at titles. They are entirely made up and meaningless in this industry. You can leave the company, found a startup as 'Founder/CEO', sell it and make yourself CEO of Product/VP or President of new company and framing that as 'career growth'.

Lastly, in a world where we have 'vibe-coders', 'AI builders' openly admitting that they have not written a single line of code before and are shipping products like sandcastles into production instead of a production-grade secure fortress, the latter being robust against security threats, made out of 'best practices' and stands the test of time and the former crumbles the moment you touch it or leave it.

I think you would want to know how to build secure software with best practices so that almost no-one can attack your software and is even also willing to pay for it.

Kinetic energy is a bad metric. Acceleration is what splats people.

Jumping out of a plane wearing a parachute vs jumping off a building without one.

But acceleration is hard to calculate without knowing time or distance (assuming it's even linear) and you don't get that exponent over velocity yielding you a big number that's great for heartstring grabbing and appealing to emotion hence why nobody ever uses it.

Unfortunately, this extends to research studies. My mother enrolled me in the Growing Up Today Study (https://gutsweb.org/). I eventually stopped responding to that, as I couldn't see how any child (or even adult) could answer their questions on estimated food consumption remotely accurately, making the whole thing seeming dubiously ethical.

It's cited constantly in the research on ultra-processed food you see these days.

Getting an e-bike has got me out getting exercise way more than a regular bike ever did. Being able to dial my effort up and down pushes me further, quite literally in distance and fitness goals. I'm by no means fit and almost did a 5 hour 40 mile ride one day. I completely used up the battery in that time, my legs were cooked from the effort. I would have never attempted something like that on a regular bike unless I was fit.

Chisel picked up Scala 3 support in 7.0.0 released last September (https://github.com/chipsalliance/chisel/releases/tag/v7.0.0), right now they cross-compile between Scala 2 and 3 but from what I heard they should eventually move to Scala 3 only to start taking advantage of new features like named tuples (https://docs.scala-lang.org/scala3/reference/other-new-featu...).

The most surprising thing on this page for me was:

> The areas of least atmospheric humidity ... a large area of ‘dry’ atmosphere also covers part of the South Atlantic Ocean (centre of image).

This area is not that far south as to basically indicate the antarctic, and it is warm season in the southern hemisphere. I did not even think it would be possible to have a larger area of low humidity over a massive ocean like that.

Wow, you did a lot of releases since then !
I was running the 0.1.15, so it can explain some discrepancies.
No problem on linux with the last release, will try the "freshly" released 0.1.97 on windows also (I think the issue was on this OS).
And I promise I'll create an issue if I encounter some difficulty.

Thanks a lot for this editor, I'll dive into it.

> I feel like you have to say this out loud because many people in these discussions don't share this view. Billion dollar corporate experiments conducted in public are sacrosanct for some reason.

Yes, and I find it annoying that some people do seem to think Waymo should never be criticized. That said, we already have an astounding amount of data, and that data clearly shows that the experiment is successful in reducing crashes. Waymos are absolutely, without question already making streets safer than if humans were driving those cars.

> If you want to spend your efforts improving safety _anywhere_ it's right here.

We can and should do both. And as your comment seems to imply but does not explicitly state, we should also improve road design to be safer, which Europe absolutely kicks America's ass on.

Most of my customers (small VPS host here) don't like the companies behind AWS, Azure, and Google Cloud, especially the amount of influence they have in the world and how they wield it. And the pricing often isn't that much different between a small VPS host and either a cloud provider or one of the larger VPS providers (Akamai/Linode, Digital Ocean, etc.) - larger providers have eoncomies of scale, but smaller providers don't have as much overhead for paying sales and C-suite.

There's also the human touch in terms of who you talk to: a lot of the smallest VPS hosts are 1-2 people, both technical, so customer support = sysadmin = contact for everything.

I agree. So many TUIs from webshit devs don't even bother to call isatty, let alone check terminfo to see if ANSI escape codes are even valid for this terminal.

But modern open source subscribes to Mao's Continuous Revolution Theory. Calls for some measure of stability and sanity are usually dismissed with some form of the argument "awwww, is poor diddums afwaid of a widdle change?" Or in this case, "still using vi on your ADM3A, old timer? Our software is not for you."

Here’s the thing I don’t get about module partitions: They only seem to allow one level of encapsulation.

Program
- Module
- Module Partition

whereas in module systems that support module visibility, like Rust’s, you can decompose your program at multiple abstraction levels:

Program
- Private Module
- Private Module
- Private Module
- Public Module
- Public Module

Maybe I am missing something. It seems like you will have to rely on discipline and documentation to enforce clean code layering in C++.

Every cargo shipment entering the U.S. generates a customs manifest—product descriptions, quantities, ports, shippers, and declared values. 8,818 Ferraris were detected in U.S. customs data from 2020–2026, averaging 121 per month. Import volumes correlate with Bitcoin (+0.70), S&P 500 (+0.74), and NASDAQ (+0.68).

Depends on where the Waymo was.

The 15 mph speed limit starts on the block the school is on. The article says the Waymo was within two blocks of the school, so it's possible they were in a 25 mph zone.

The entire sentence is even less enthusiastic:

"The GPU die will remain with TSMC, but portions of the I/O die are expected to leverage Intel's 18A or the planned 14A process slated for 2028, contingent on yield improvements."

Reading between the lines: Nvidia will most likely design a TSMC version of those I/O die portions in case Intel fails.

Intel has a decades long reputation of failing its attempted foundry customers. Whether or not Nvidia's ownership stake is sufficient to overcome the inertia within Intel that has resulted in those failures remains to be seen.

I think I read somewhere that the model T went something like 12 years without substantial changes to its design.

From 2028.

And this is about industrial robots, which is much easier to handle than what household robots supposed to be about. Will we ever see a robot that will be able to take grandma to the tub and clean here, to then carry her up the stairs to bed, without killing her? I doubt it.

And finally: Boston Dynamics has actual working products for ages now. They don't need to cheat by using RC toy remote controllers to control their robots. And they are doing serious expectation management. This is completely different league than what Musk is doing.

Also, I don't think it's desirable to have robots taking away human work without first solving the question "and what are we going to do with all the unemployed?".

Your median human driver? Sadly, I think not. Most would be rushing, or distracted, or careless.

The DSM-5 work group chair said the move was based on brain imaging showing gambling activates reward systems like drugs do [1]. That's not grandfathering, that's reclassification based on neuroscience. Your source is a comparison table of criteria, not a rationale for the reclassification.

The WHO recognized gaming disorder in 2019. The field is expanding. But even if it never formally recognizes social media addiction—call it whatever you want.

I'm assuming good faith, though you are putting words in my mouth. I said social media is a cheap, shitty, and extremely addictive drug. I'm happy to rephrase that to 'cheap, shitty, and extremely compulsive in ways that damage health, relationships, attention and has immensely negative effects for society as a whole.' I never once mentioned government regulation, you can reread my comments.

My opinion is that people should view it as lame and self regulate. I do not think it is likely to happen.

So, I wanted to avoid referring to this case because it undermines any discussion, but if you want to include it, the judge ruled in favor of Apple for nine out of ten claims made by Epic, including 1) Apple's 30% commission is not anticompetitive behavior, and 2) Apple has the right to not allow third-party apps on their platform. Apple, being Apple, attempted to subvert the part about allowing links to other storefronts by adding a 27% commission aas well as a scare page, which is what they are currently in hot water for. However, the overall decision was solidly in Apple's favor regarding the App Store's 30% commission and practices.

> One, after trial, the Court found that Apple’s 30 percent commission “allowed it to reap supracompetitive operating margins” and was not tied to the value of its intellectual property, and thus, was anticompetitive.

Epic is twisting other people's words here. Notice how they quote “allowed it to reap supracompetitive operating margins” but not the point about it being anticompetitive. It's because the decision never said that.
