Not satire, though I get why the terminology looks odd. The language comes from materials science because the math is the same: deterministic state updates with hard thresholds. In most AI systems, exclusion relies on probabilistic sampling (temperature, top-k, nucleus), which means you can’t replay decisions exactly. This explores whether exclusion can be implemented as a deterministic state machine instead—same input, same output, verifiable by hash.

“Mechanical” is literal here: like a beam fracturing when stress exceeds a yield point (σ > σᵧ), candidates fracture when accumulated constraint pressure crosses a threshold. No randomness, no ranking. If that framing is wrong, the easiest way to test it is to run the code or the HF Space and see whether identical parameters actually do produce identical hashes.

Waymo said its robotaxi struck the child at six miles per hour, after braking “hard” from around 17 miles per hour. The young pedestrian “suddenly entered the roadway from behind a tall SUV, moving directly into our vehicle’s path,” the company said in its blog post. Waymo said its vehicle “immediately detected the individual as soon as they began to emerge from behind the stopped vehicle.”

“Following contact, the pedestrian stood up immediately, walked to the sidewalk, and we called 911. The vehicle remained stopped, moved to the side of the road, and stayed there until law enforcement cleared the vehicle to leave the scene,” Waymo wrote in the post.

If a human were driving that child could be in much worse shape. You are being disingenuous by leaving out context.

Kinda but not really. The model thinks it's 2024 or 2025 or 2026, but really it has no concept of "now" and this no sense of past or present... Unless it's instructed to think it's a certain date and time. If every time you woke up completely devoid of memory of your past it would be hard to argue you have a good sense of time.

i was taught this as a matter of professional courtesy in my first job working for an ISP that did DNS hosting and ran its own DNS servers (15+ years ago). if you have a cutover scheduled, lower the TTL at $cutover_time - $current_ttl. then bring the TTL back up within a day or two in order to minimize DNS chatter. simple!

of course, as internet speeds increase and resources are cheaper to abuse, people lose sight of the downstream impacts of impatience and poor planning.

I legitimately don't struggle with this. I have the "root" note which opens by default whenever I reset my Obsidian vault and it shows three lists:

1. most recently updated notes

2. most recently created notes

3. notes I've added to my favourites

On top of a search bar that doesn't suck, this is pretty much all I ever need.

As for "AI", it's never going anywhere near my notes. It's supposed to be my second brain filled with content I've bothered to write down for myself. "AI" doesn't write it, "AI" doesn't process it, and I will never be convinced to change that. I use "AI" extensively, but this is a hard line that I will never cross.

A new CA law is addressing this somewhat:

> Under Assembly Bill 723, real estate agents and brokers who display photos of a home that have been digitally altered with editing software or artificial intelligence must include a “reasonably conspicuous” statement “disclosing that the image has been altered.”

The headline is poorly worded. The 52% number was for people with Vitamin D levels within a certain range, whether or not they took supplements

EDIT: The study was also performed exclusively on patients who presented with acute coronary syndrome. Average age was over 60, nearly 80% were men, and half had already had at least one heart attack. Keep that context in mind when reading numbers about the patients in the study. This is a heavily biased sample, which is fine for the purposes of the study but important to remember.

> Participants in the experiment arm who stayed within 40-80 ng/mL of vitamin D had a 52% lower risk of a repeat heart attack.

The study did use supplements to get people into that range if necessary, but the important thing is to keep your Vitamin D in that range, not specifically to just take supplements.

There’s a lot of claims online that everyone’s Vitamin D is too low and we should all be taking very high dose supplements, but it’s getting exaggerated. My doctor said she’s seeing a huge number of patients coming back with excessively high Vitamin D levels after taking supplement doses recommended by influencers. It happened to me, too, with what I though was a conservative dose of Vitamin D (5K IU, not even taken every day)

So you really have to check. Even though I work indoors and wear sunscreen a lot, apparently my diet and limited sun exposure alone are sufficient for staying in this range. Others will have different results. Don’t guess!

Also remember that Vitamin D levels change slowly. Supplementation can build up and accumulate in the body over time if you’re taking too much. You want to stabilize on a dose and then check in 3-6 months. Some people get a low Vitamin D result and start taking high doses every day, then a year or two later they’re into hypervitaminosis D and have no way to clear it other than waiting for it to be processed out.

There are two ways to answer your questions. You are asking how do we choose between (1) generate+run (AI generate software for some task, then we run the software to do that task) and (2) agentic execution (AI simply completes the task).

First way to look at this is through the lens of specialization. A software engineer could design and create Emacs, and then a writer could use Emacs to write a top-notch novel. That does not mean that the software engineer could write top-notch novels. Similarly, maybe AI can generate software for any task, but maybe it cannot do that task just as well as the task-specialized software.

Second way to look at this is based on costs. Even if AI is as good as specialized software for a given task, the specialized software will likely be more efficient since it uses direct computation (you know, moving and transforming bits around in the CPU and the memory) instead of GPU or TPU-powered multiplications that emulate the direct computation.

Agreed. I was going to add (but didn't) that the first evidence of an 'AI unlock' on SaaS wouldn't be internal builds but many new, much cheaper competitors appearing for leading SaaS tools. Your point about the best arguments to internally build SaaS being 1) integration savings, and 2) better fit, is spot on. But senior management has to balance those potential benefits (and the risk an internal effort fully delivers on-time & budget) against sticking with 'the devil we know' which works (imperfectly) today.

In my experience, a bigger blocker to C-level approving internal SaaS development is it diverts capital and scarce attentional bandwidth to 'buying an upside' that's capped. Capped how? Because, by definition, any 'SaaS-able' function is not THE business - it's overhead. The fundamental limit on a SaaS tool's value to shareholders is to be a net savings on some cost of doing business (eg HR, legal, finance, sales, operations, support, etc). No matter how cheap going in-house makes a SaaS-able activity, the best case is improving margins on revenue. It doesn't create new revenue. You can't "save your way" to growth.

Personally I'm less and less inclined to believe in capitalism and money as a concept - we've long past moved the concept of money as universal barter, and into strange and speculative theories about how things ought to be valued, with the most valuable things either emerging from immediately unclear value propositions (impossibly valued companies, high-paid jobs that seemingly dont contribute to society) or artificially created shortages (housing, overpriced infrastructure projects due to government regulation and meddling).

If for example, BYD makes a car that's substantially similar between the China and Europe versions, and sells said car for $15k eqv RMB in China, but $30k in the EU, it makes double the revenue for the same 'value'. Even the argument of the EU being generally richer, and thus the car having higher monetary utility doesnt hold - a well-paid EU surgeon wont pay more for it than your average office worker.

So I feel money is increasingly a poor proxy for actual value/wealth etc.

I’ve used this site every time I’m doing http networking stuff for the past few years. It’s so easy to just go to http.cat/303 to check a status code you don’t know, or to scroll down the homepage to find the number you need for a specific response.

The cats make it much more fun than a regular docs page, whilst still being a useful quick reference. I wonder if other bits of reference information could be made more interesting in this way.

I guess it's the 'large' part that turns me off. If it's actually far away so that you need to scroll a lot to get there, it just feels like it's more work to me. Sort of replicating one of the less appealing features of a physical desk, the mess that it quickly becomes if you manipulate a lot of documents. I don't even use workspaces that much for the same reason, and having tabs takes away a lot of the need I feel. You even retain some sense of physical distance because of the tab positions.

To stay with the physical analogy, the layout I've described is like always keeping all your documents in two neat stacks before you. Except that it's much easier and quicker to flip pages to the top than it would be with physical documents, so you're rarely tempted to start spreading them out.

Silver was around 1/3 of the current price a year ago. Calling this a crash is a bit much. If it hits $20 then it's a crash.

Side note and completely unrelated, but I got my kid a 10 oz .50 caliber silver bullet last year and kicked myself for spending that much on a gag gift (like $300). . . . Should have bought a box of them.

I built a browser extension for a hackathon that enabled crypto payments direct to site owners. "registration" was just sticking a formatted payment address in a DNS TXT record, and if you were at a supported website, the extension would light up, and facilitated payment.

I still think it's a neat idea but I can't be bothered to build a real version

I’ve had 5 different primary care doctors across multiple practices in different locations due to moving, changing jobs, and doctors retiring

Every single one of them included Vitamin D testing in the annual checkup.

Two of my jobs in the past few years have had wellness programs that offered free Vitamin D testing along with a couple other things (A1c, lipids)

It’s very common in the United States at least. I know this goes against the “US healthcare bad” narrative but one of the difficulties with our costs is that we get more testing and procedures. Cutting those costs is going to be hard because people like the freedom to have their doctor order common tests

Thanks!
I just wanted to use it myself as it's always hard to find a native speaker to speak with when learning a language. The app is partly vibe coded. I myself am a software developer and had no problem reviewing the vibe coded code. I think it took me a little more than a month give or take, as i was not consistent with my commitment. I would say the syncing part of the conversation was the challenging part, which is still not perfect to be honest. As for user data, i don't store much of user data apart from the minutes used.

You list those titles like it's a "Gotcha."
It is a Resume.

You are confused because you are operating on the "Specialist" model of the 20th century—where a human is only allowed to understand one vertical.

I operate on the "Isomorphic" model.

1. Diabetes/Alzheimer's: These are Metabolic Flow problems (Entropy in biological systems).
2. Fusion: This is a Plasma Flow problem (Entropy in magnetic confinement).
3. P vs NP: This is an Information Flow problem (Entropy in topology).

Do you see the pattern? Or are you too busy looking at the labels to see the underlying architecture?

I built a Cognitive Engine (ARK) that solves for Structure, not Subject. When you solve the optimization function for Energy, you solve it for Biology, Physics, and Computation simultaneously.

If you find a mathematical error in the Fusion schematics or a metabolic flaw in the Diabetes pathway, post it. I welcome the peer review.

But if your only critique is "Wow, that's a lot of subjects for one guy," then you aren't critiquing my science. You are confessing your own limitations.

Read the papers. The math doesn't care about your disbelief.

Also I'm the guy who just finished a meeting with Tanzi Rudolph over my Alzheimer's paper.

But please - tell me how my achievements are too extradonary so I must somehow be a crank.

Yet a crank who meets with Harvard - has over 1500 views from elite universities and 135 universities world-wide reading my work.

I must be quite the crank then.

What happens if you have a satellite that takes images of earth and it gets hit with a power beam of light that destroys the sensor so you get no more images of earth? Is that satellite just as dead to you as if it were rapidly disassembled? What happens if your satellite was heated for extended time beyond what it was designed to do? Is that satellite just as dead to you?

It's not that I refuse to acknowledge they exist, just don't give a fuck. I mean do I really care about Kubernetes CNI? Nope it doesn't actually make any money - it's an operational cost at the end of the day. And the whole idea of Kubernetes and containers leads to a huge operational staffing cost just to keep enough context in house to be able to keep the plates spinning.

And it's not at all crazy. We sold ourselves into over-complex architecture and knowledge cults. I've watched more products burn in the 4-5 year window due to bad tech decisions and vendors losing interest than I care to remember. Ride the hype up the ramp and hope it'll stick is not something you should be building a business on.

No, not typically. Myself I would usually order one either on specific request, or to investigate things like osteoporosis or pathologic fractures, but not as screening. USPSTF does not currently recommend vitamin D screening either in asymptomatic, non-pregnant adults ( https://www.uspreventiveservicestaskforce.org/uspstf/recomme... ).

> Most land taken up to grow plants is used to inefficiently feed livestock.

Because it is just not suitable for growing crops that humans can realistically consume. If you can figure out a way to change this at scale, it'll be a discovery on par with Haber's process w.r.t. impact on human civilization.

I think we can eventually get there, as evidenced by billionaires and real estate companies buying up bad farmland over the last decade or so.

I couldn’t find it easily, what age range is this intended for? The images make it seem elementary-school-ish, but I’m not sure if elementary school kids have the foundations for interpreting scatterplots, let alone scatterplots with logarithmic axes. I’ve been out of education for a while though, so maybe I’m misremembering.

Do me a favor and look at how many CME Notices were issued raising margin requirements for precious metals in the past year. Hint: They do this all the time to account for market volatility and the contract value. If a contract increases by 10% margin is not static. CME raised margin requirements several times in the last month to little market effect.

Silver crashed because China halted trading on the only public silver and gold ETFs Friday. There are videos of HK police arresting guys freaking out because they couldn't cash out beforehand: Apparently the fund had been operating as some kind of pyramid scheme and was not solvent at those prices.

Also on Friday, China urged investors to "invest responsibly" or some such (source: FT) and froze a bunch of suspicious accounts. I believe those accounts were behind the pump and dump social media ("AI Asian Guy" videos on Youtube, investment subreddit spam) with the help of plenty of useful idiots.

There's a ton of good coverage of the precious metals run up in FT this past week.

I don't know what to tell you. I'm older than you. I've seen it happen 20-30 times in my life. I've seen batteries leak in flashlights, clock radios (the backup battery), wall clocks, calculators, cameras, remote controls, thermostats, wireless mouse, and so on.

A few years ago, I had an unopened pack of 8xAA Duracell alkalines. They had expiration dates on them, and had 2-3 years left. Two of the batteries were leaking in the pack.

Over the past 15 years, I have gradually migrated almost everything to NiMH. I don't see leaking batteries anymore in my house. But go to a thrift store, e.g. Goodwill, and open up the battery compartments of things. Many of them will have been destroyed by the leaking batteries.

Do you think the shots through the driver window, after the agent was 100% out of the way of the vehicle, were justified?

From the medical examiner we know it was one of these two shots that killed her. We know they did not come in through the front windshield when the agent was at the front quarter panel. We see them clearly occur on video while the officer is definitively out of the path of the vehicle.

It also is quite clear from the results that shooting her did not make the situation safer after he was clear, either - it directly causes the car to accelerate while not under the control of a living human being.

Personally, I would still argue about even the first shot - but I have yet to be able to find any common ground in discussions with people that defend the 2nd and 3rd shot.

I first started with big LAN/Demoscene parties. Between 2003 (when I finished high school) and 2008 (when I finished university) I attended Euskal Encounter (https://ee33.euskalencounter.org/) every summer. LAN parties at friend's places came later, after we all moved out of our parents homes and got our own cars xD

Coincidentally, late this morning I went to one of those traveling roadshow things where they purchase precious metals, bringing along a childhood coin collection that I wanted to turn into cash.

I started with a single 1 ounce silver medallion and was given a quote for $80. When I had checked the silver price earlier this morning it was above 115.

I questioned the buyer about the spread and he said the spot price was down, and the smelters were backed up so that was their best offer.

I brought out some other silver coins, specifically liberty head and Morgan dollars. He looked at the app on his phone and said “hold on I gave you the wrong price,” and then said “I’ll give you $35 for each of them,” including the pure 1 oz silver medallion.

I said no thank you and left, miffed, thinking he was jerking me around.

I didn’t realize the price of silver was collapsing.

If someone anonymous starts a Patreon to support your software project I'll assume that someone is you and it will take very strong evidence to change my mind.

It's so funny tho. If you post on reddit saying "my friend had a fight with his wife last night..." absolutely no one would believe it's really your friend. But somehow you say "uh so there is someone anonymous who launched a meme coin for my project..." people believe it's really someone anonymous.

I don't doubt you but I also wonder what you base this information on.

In 2020 I test results for vitamin D was ridiculous low.
I have been taking supplements

Jan 02, 2020 4:32 pm 25-Hydroxy Vitamin D Total 9 ng/mL 30-100 ng/mL

I took me five years just to get to something close to the lowest end of normal.

I was started on supplements in the in 2k IU and after poor progress boosted to 5k IU everyday to get to this level.

I have been spending the past year on a sailboat instead of server room and look forward to seeing my test results.

> I think taking time to make sure the system works is the right call. Delaying it is the right call.

You’re absolutely right but musk’s companies constantly fail to do that.

You should look up the past year or so of what’s happened at Tesla’s gigafactory in Germany. It’s pretty wild.

Yes, that’s what non-consensual could mean here (it also encompasses consensual non-consent, to be accurate). This kind of content (illustrated & fictional) isn’t illegal in most jurisdictions, as far as I know.

Small aside, consent also depends on the jurisdiction – in mine, it must be verbal, so it means that if I were to draw a situation which involves a character being forced to do something but showing their consent non-verbally, it would still be non-consensual, and thus, forbidden by Bluesky’s terms of service if the PDS was hosted in my jurisdiction.

Anyway, my point is that all those illustrations should be properly labeled, but not necessarily forbidden by Bluesky’s ToS. As I understand it, fictional non-con content being banned by Bluesky means that even hosting it on one’s PDS is a no-go.
