I know someone who started an elder care business with explicitly this purpose. He stopped working in the more conventional medical system because he saw an opportunity. Unsure how it is going at this point, I haven't checked in recently.

Elder care is hard, and expensive. Friends have worked in various levels of it at various times, from food services on up. There is clearly some good for people to be around a community and there are real needs that require constant attention for some. But there is a drive to do more with less which almost always seems to end up with stories of people not being attended to as quickly as you might hope.

Memory care is particularly difficult, on the family and on the businesses. It is just so all consuming and from the outside it can be hard to know if adequate care is being taken. Of course I do know someone who's mom put her dad into memory care, then moved and basically started a new life with a boyfriend while still married so she had access to the money.

My parent's solution is to day they don't want to draw things out. But I think that is easy to say from a position of health and barring any significant diagnosis there is more of a slow slide to infirmity than a clear juncture to make such a choice. We'll see, my family is close and I expect we will provide care in person. But also life is complicated and that is a ways off.

A walkthrough would be nice, but he's got a lot of understandable material linked on that page. For example, here's an overview of the binary lambda calculus: https://tromp.github.io/cl/Binary_lambda_calculus.html

And here's a readable and fascinating post on "the largest number that's representable in 64 bits": https://tromp.github.io/blog/2023/11/24/largest-number.

If you go through these and find some interesting things, it'd be worth posting to HN.

On the one hand, this seems nuts. On the other hand, the mechanism compared to all the other things biology can and has done doesn't seem that crazy.

Create egg, remove nucleus of egg, replace nucleus of egg with one or two nuclei from stored sperm that initiate replication and growth of the other species from there (depending on the exact mechanism which it sounds like they're still figuring out).

Compared with fungus that creates zombie ants (this is a real thing - https://en.wikipedia.org/wiki/Ophiocordyceps_unilateralis) and birds that change their eggs to match those of other species (https://en.wikipedia.org/wiki/Brood_parasitism) it almost seems tame.

This seems on the surface to violate Hamilton's Law (rB > C)

The hybrid worker ants should still share 75% of their DNA with the queen and therefore it makes sense for them to cooperate regardless of the source of DNA for their father.

The M. structor male clones however do not share any DNA with the queen presumably.

I wouldn't be surprised if further studies found that the M. structor genes were behaving selfishly. They must have some sort of aggressive mechanism for hijacking and evicting the queen genes for making clones.

Alternatively there could be a parasitic organism propagating through the reproductive procress.

> Why those stories never broke through to the mainstream is an interesting question.

The mainstream media in the US has never been great at communicating any story with nuance or depth. In the 80s and 90s, foods that we've eaten forever were being demonized, like eggs. In 2020, people were being told they shouldn't go outside lest they come within 100 feet of another person.

To their credit, the general population has never had a shorter attention span and so easily hoodwinked into believing misleading claims.

I was at the same place you are for a while until I realized my obsession with doing everything "right" was killing my enjoyment of programming. I read through Let Over Lambda a couple of months ago and was blown away at how deeply unmaintainable some of his code examples are, but I got inspired to start letting myself do weird unmaintainable shit while programming instead of constantly acting like my code has to pass a code review and I've found its a lot more fun.

I'm the contractor responsible for SL's Luau VM integration, appreciate the kind words about the Luau integration!

We're still in figuring out our async strategy for user-facing APIs to be honest, so these references are super helpful. We already have preemptive scheduling of execution, but it's most likely to be some kind of wrapper around `coroutine.create()` where an event loop is responsible for driving execution flow and internal `coroutine.yield()`s let you specify what you're `await`ing.

We'll likely have an RFC for how that will all work within the year, but several users have written their own bespoke `async` / `await` implementations for SL in Lua already.

A student filmed the class, and asked the professor if it was legal to teach the class content. Class content that mentions the existence of gender.

The video went viral, and the professor and multiple school administrators have been fired as a result.

As far as I can tell, it is probably legal, and also aligns with school policy. The current government of Texas is trying very hard to change that.

Europe spends more on academic research than the US, both in absolute terms and as a fraction of GDP. The US is ahead in business R&D.

But research funding is mostly used for hiring early-career researchers for fixed-term positions. If Europe wants to attract foreign academic talent, its universities need permanent increases in core funding for hiring additional faculty. And that's something European politicians largely don't support.

People didn't used to expose themselves to as much direct sun and covered themselves with a lot more clothes. Traditional clothing in arid sunny areas typically covers everything, look at people in the middle east today.

I live in a very sunny desert area and it's kind of funny when people assume people from here would be "more tanned". We stay in the shade, the sun will kill you! Anyone working outside is wearing wide brimmed hats and typically has all of their skin covered with clothing even in the heat, people typically have their faces covered with cloth as well.

Spending time outside with minimal clothing in direct midday sun is a modern weird behavior.

I live near an intersection where the road design encourages people to speed, and there's an accident about month. So far I've encountered flipped over cars, cars wrapped around mapposts, embedded in walls, and cars on fire. I've been first on the scene in a lot of accidents, around 40 over the years. Never once have I been unable to get the door open to talk to the driver and help them out of the vehicle.

I've revisited this idea/protocol a few times and still have my doubts:

* is there even a need for it? I would say that most people are quite happy with centralized platforms; I don't see it changing anytime soon (why?)

* wouldn't we end up in the centralized world anyways? Even though there could be multiple NOSTR clients and relays, we all know how network effect works - people will flock to a single or a few best ones; does it really change the situation that we have today - a few centralized platforms?

* I don't see clear incentives in this protocol that would improve current social media landscape - granted that I don't particularly like current ads/sell your attention model

I am not sure that having a protocol like this is better that having a few centralized platforms - today's situation. Not to even mention technical challenges and worse user experience that NOSTR brings

I've seen this in Europe since I was pretty young as well. Usually they were little entries on the edge of the placemats that looked like classifieds. Advertising hotels, museums, and maybe shops? I can't fully picture them but I'm pretty sure I've seen something like this in french, italian, english, dutch, and maybe danish or german? It might have something to do with where we stayed or ate but in general my travel has been business focused and we have been in smaller towns.

You're assuming that arguing in court over being allowed to use 1 specific word in a commercial context is a good thing to spend $200,000 on at all, which is quite an assumption, regardless of who does the arguing.

I agree with you that it'd be better if Deno took your suggestion, and spent the money on a Programming Geek, rather than being distracted from their core mission for trivial, semantic matters. The latter is how we actually end up with critical infra like OpenSSL being maintained ad hoc by some devoted geek for a pittance, who inevitably can't keep up with critical patches.

I mean, I'll be the first to admit that I've argued about a word on the internet before, but at no point did it ever cross my mind that I should spend $200,000 doing so.

I tend to generally agree with complaints in this vein, but the language of the article, together with a seemingly intentionally old photo of Mark where he's looking extremely young, really rubbed me the wrong way and felt like a smear campaign instead of a well reasoned argument.

There's a funny correlation with UC Berkeley comp sci requirements. Dot com bubble pushed the minimum GPA to declare up. Bubble burst, GPA requirement went down. 2014-2018 it crept up again.

I could've been annoyed that everyone was doing it for the money while I really cared, but you know what, most people cannot afford to go to college for a low paying career. And I took a high paying job in the end when I could've easily done research or tinkering instead, so can't complain.

Now if anything, I'm pissed off at the few coworkers who also care a lot and act superior doing stuff the "real coder" ways, actually don't get very much done, and hold others back.

Note that the author of the article is doing webdev, which by now ought to be as routine as using PowerPoint. It's rather embarrassing that it's not.

For 8+ bays you just need a SAS HBA card and one free PCI-E slot. Not to mention that many motherboards will have 6+ SATA ports already.

If anything, 2nd hand AMD gaming rigs make more sense than old servers. I say that as someone with always off r720xd at home due to noise and heat. It was fun when I bought it during winter years ago, until summer came.

This is correct. HN is full of people making mid 6 figures that can't seem to get over the idea that people making 7 figures or more are doing it unfairly just because those people aren't scaled up versions of themselves. You don't have to be smarter than a good engineer to be a good founder or CEO because it's fundamentally a different skill set and risk tolerance. They latch onto single cases of fraud and generalize it to all rich people because it is convenient. Of course theft and fraud occurs at all levels on the org chart, but it doesn't make the news when some IC steals a couple hundred K from his company.

I guess that AI will embody parts of our intelligence and experiences in the same way as we have assimilated our long term ancestors experiences. There are remnants of their system in our system. Parts that we might not be able to introspect even with a superior intellect. Likewise the AI stand on the shoulders of our experiences and our ways of perceiving them. Sight, sound, language thus far. But the experience that shaped us may not be available to them, especially in the long term. Our experience may just be a faint echo from the past to them, a hunch they can’t explain, a preference that doesn’t make any logical sense to them.

Will they trick us? Absolutely, but we will always trick them. There are remnants of our system in their system.

Who says it's dead, people opening issues? Guess I've never made a popular enough repo to even get there.

> Why would you want to memorise a password?

You'll definitely want to memorize the password to the backup service that has the last copy of your password vault after a disaster. :P

> Writing your passwords down on paper is actually less crazy than it sounds

I agree that physical security can be incredibly useful against a lot of modern threats... but we can do better. I wish there was a dedicated password-keeper device format of:

* A small keyboard and screen

* The data encrypted at rest by one master password

* Only permits upload/download of the the encrypted file over USB. With some companion software, you just plug it into your computer, computer copies the encrypted file to somewhere on disk that gets regularly backed up, the disconnects and beeps to tell you it's done.

* Sturdy enough that any "Evil Maid" attack needs to be done by a professional rather than a conniving roommate or jilted partner.

* Tracks history of entries, last-changed, etc.

For anyone interested in playing with distributed systems, I'd really recommend getting a single machine with latest 16-core CPU from AMD and just running 8 virtual machines on it. 8 virtual machines, with 4 hyper threads pinned per machine, and 1/8 of total RAM per machine. Create a network between them virtually within your virtualization software of choice (such as Proxmox).

And suddenly you can start playing with distributed software, even though it's running on a single machine. For resiliency tests you can unplug one machine at a time with a single click. It will annihilate a Pi cluster in Perf/W as well, and you don't have to assemble a complex web of components to make it work. Just a single CPU, motherboard, m.2 SSD, and two sticks of RAM.

Naturally, using a high core count machine without virtualization will get you best overall Perf/W in most benchmarks. What's also important but often not highlighted in benchmarks in Idle W if you'd like to keep your cluster running, and only use it occasionally.

There is no reason why a manual handle should not be able to trigger the window motor before releasing the door catch or even pull the window down itself. There are vehicles with frameless windows that have more conventional door handles.

But I have to say that I prefer the handles on my Model S to those on the Model 3. Tesla loaned a Model 3 to me while they replaced the battery in my Model S. Even after three weeks the Model 3 handles steel seemed awkward to me.

Kinetic theory stuff for one, like deposition, growth, sandpile type things. Complex networks and lots of dynamics stuff falls under statistical physics umbrella but not statistical mechanics. Stat mech's amazingly wide applicability makes it easy to think it's THE approach to approaching things statistically, but it's not. The broad encompassing approach has a name, statistical physics.

I think the Mac Studio is a poor fit for gpt-oss-120b.

On my 96 GB DDR5-6000 + RTX 5090 box, I see ~20s prefill latency for a 65k prompt and ~40 tok/s decode, even with most experts on the CPU.

A Mac Studio will decode faster than that, but prefill will be 10s of times slower due to much lower raw compute vs a high-end GPU. For long prompts that can make it effectively unusable. That’s what the parent was getting at. You will hit this long before 65k context.

If you have time, could you share numbers for something like:

llama-bench -m <path-to-gpt-oss-120b.gguf> -ngl 999 -fa 1 --mmap 0 -p 65536 -b 4096 -ub 4096

Edit: The only Mac Studio pp65536 datapoint I’ve found is this Reddit thread:

https://old.reddit.com/r/LocalLLaMA/comments/1jq13ik/mac_stu ...

They report ~43.2 minutes prefill latency for a 65k prompt on a 2-bit DeepSeek quant. Gpt-oss-120b should be faster than that, but still very slow.

Could be just envy.

I'd say the clearest example would Steve Jobs vs Wozniak. They were equal partners with Woz doing far more of the work. At nearly every turn, Jobs took the opportunity to stab people in the back if it'd personally enrich him. Jobs ended up running Apple and a billionare while Woz ended up a millionaire.

Part of the reason Woz didn't end up as rich as Jobs is because when moral problems came up, he was the one willing to cut into his own wealth and finances to "make things right".

People that become billionaires do not care about making things right or fair. They care about accruing wealth.

There are examples of that everywhere. Tesla would be another. Elon became absurdly wealthy off the backs of underpaid and overworked employees. The early days of tesla/spacex he sold the idea that "you'll change the world!" to undercut the salary of his employees.

Now, these could be just specific shitty examples. There may in fact be a number of billionaires that have treated their employees fairly and given back to the system that got them there. But I'm decreasingly convinced that that is really the case.

I think it's worth knowing that the cryptography in Nostr appears to be a wreck. Here's a paper from EuroS&P this year, also presented at Black Hat on the crypto track:

https://eprint.iacr.org/2025/1459.pdf

The vulnerabilities here are pretty :yikes:

* The event protocol that drives the system doesn't authenticate public keys, so asymmetric signatures are performative: attackers that can intercept messages (Nostr servers, the presumed adversary of an E2EE messaging system) can just swap out keys and re-sign.

* Two major clients, the mobile phone Damus app and the web Iris app, don't even verify signatures to begin with.

* DMs in this system are unauthenticated CBC, so attackers can simply bitflip messages and events to say what they want.

* The apps do automatic link-preview, so they've managed to reconstitute the EFAIL attack: attackers can locate links within messages (they'll be revealed by SNI and DNS anyways) and then bitflip them to point to attacker-controlled servers, exposing both the URLs (which will often contain tokens) and, with a bit of extra work, the message itself (by tacking `?foo=` onto a URL).

* There's no key separation in the system, so you can trick users into running a subprotocol other than the messaging system, then establishing a session key, which will then be used for messaging.

These are really basic errors; this is mid-aughts-level cryptographic engineering. There are probably a variety of other reasons to use Nostr, but end-to-end security does not appear to be one of them.

> The Tennessee Valley Authority, the largest public power supplier in the US, brought down one of the massive cooling towers at the abandoned Hartsville nuclear power plant in a controlled implosion.

> Construction of the power plant was halted in the 1980s before it ever produced electricity. The site has remained dormant for decades.

> The 540-foot cooling tower was brought down to make way for future development, according to TVA officials.

> The TVA told the BBC that the demolition used more than 900 pounds of explosives and took less than 10 seconds.

I have been tracking my airquality with a device called AirQ Pro / Science

What i like about this device that they give a very precisce and clear physical definition of each metric and explain by what quantitative factors the metric is influenced.

incl. potential measurement error sources and ability's to reset sensors.

Definitely recommend this over other air quality devices that try to simplify all the measurements into good/bad..

Have you ever wiped the top of the cabinets in your kitchen? Mine always get coated in grease. It is almost like the oil is being atomized like perfume. Hood works great with smoke testing but this still happens. Inside of the hood is also extremely gross to the point where the oil condenses and drips if I forget to clean it for a while.

> I wish someone would explain the Anglo obsession with daily sunscreen routine.

Because it's more about skincare for physical attraction and less about the cancer. Sun ages your skin with wrinkles, sagging, hyperpigmentation, etc.

This isn't specific to Anglo nations too. Any country where being "fair skinned" is more desirable will have lots of demand for sunscreen.

I was a the kind of person who was happy as a pig in mud to be paid to do my hobby of programming computers! Was ecstatic that people would pay money to a young kid to do that!

But most of the people I went to uni to study computer science with at the end of the nineties were there for the money. Even back then it was all about money for most programmers.
