American health insurance is insurance in name only - picture health insurance models laid on top of your car:

Imagine your car gets totaled. Your insurer says, "Hey, we're going to pay out $25K for your vehicle. So you have a $1,000 deductible, so that's $24,000, and then your copay for a total loss is $2,000, so that brings us down to $22,000. For total losses, your coinsurance as your contribution for your vehicle coverage is 20%, which is $5,000, so here's a check for $17,000. But that's only if you're buying a Hyundai, otherwise the vehicle is out of network and you'll get a check for $8,500 instead."

> If you read the fine print of a health "insurance" plan at a large company, you might discover healthcare costs are directly covered by the employer and the insurance company just administers the plan according to "set rules".

Generally this is done by a TPA (third party administrator). In many ways you can do as you wish, but as insurers have already done the actuarial work, it's generally easier to use a plan and tweak it if desired (like "Give us this plan but pay for 1 massage/week") versus having to figure that out yourself.

Heh, that isn't my experience.

I created a client Linux: https://gitlab.com/kop316/gtk-meshtastic-client and even posted it on their discussion page: https://github.com/orgs/meshtastic/discussions/99 . One of the maintainers responded positively to me: https://github.com/orgs/meshtastic/discussions/99#discussion... .

I tried Pop before Bazzite on my PC back in April and maybe I’m just bad at Linux, but it was a pain in the ass for gaming at first boot. Bazzite ran Expedition 33 out the box. Didn’t have to download drivers, didn’t have to configure anything, it just worked.

There are limitations but if you want a gaming machine, bazzite is a no-brainer to me. Poo is very impressive but I just don’t want to fight my OS constantly when it comes to gaming.

> They supposedly don't care about the environment and yet we're moving the needle on that.

Actually, good call, and nice analogy, thank you. That's a nice reminder that when cause and effect are far apart, it's easy for people to not conenct the dots; it actually makes for a nice explanation, and helps me be less cynical about it.

Some PassivHaus designs incorporate such systems. There is also district thermal storage which services multiple homes with a thermal storage reservoir.

Thorstein Chlupp, of Rienna LLC, built several net-zero homes in the Fairbanks, AK, area. He hasn't been active for a number of years now, but released several videos in the mid-2010s detailing his design, construction, thought, and results.

He's apparently been with NREL since 2023: <https://research-hub.nrel.gov/en/persons/thorsten-chlupp/>.

There's a nearly-decade-later review of one of Chlupp's Alaskan homes, the Sunrise House, written in 2020 (the house was constructed in 2011): <https://www.greenbuildingadvisor.com/article/the-sunrise-hou...> (paywall).

And the original video series and channel:

<https://www.youtube.com/watch?v=AtHkvpRI6fc>

<https://www.youtube.com/@REINALLC/videos>

At the core of Chlupp's homes was a thermally-stratified 5,000 gallon storage tank. This was ideally aligned vertically (to improve thermal stratification), though at least one home had a horizontal alignment. The tank was inside the core of the home, which means it occupies significant internal space. I don't know if there have been any mechanical / technical issues with the design over time, though at least initial results were strongly positive.

In what way do you consider that to be the case? IBM's Watson defeated actual human champions in Jeopardy in 2011. Both Walmart and McDonald's notably made large investments shortly after that on custom developed AI based on Watson for business modeling and lots of other major corporations did similar things. Yes subsidizing it for the masses is nice but given the impressive technology of Watson 15 years ago I have a hard time seeing how today's generative AI is science fiction. I'm not even sure that the SOTA models could even win Jeopardy today. Watson only hallucinated facts for one answer.

This view seems to be common, but I think it misses what incredible alchemy comes from making people who come in for “job training” (like I did) spend 4 years in close proximity with research, academic freedom, liberal arts, and at least an attempt at some kind of intellectual idealism separate from economic incentive. It’s peanut butter and chocolate that has served democracy and its people well by having a middle class that is not just productive, but truly educated. It’s weird and it has problems, but it’s also wonderful, and we should not try to sever the two so we can more “efficiently” crank out credentials.

> There are already so many ways (and reasons) not to do free or open source software. People who find them convincing are using them.

To be honest, I don't think the space between GPL/MIT and commercial closed source is explored enough. I'm aware there's a few examples of things in between, but they are not common knowledge and they don't satisfy everyone. It is not a space that is easy to search online for established wisdom and comparisons in.

AFAIK -- even the "Designer" feature of Microsoft Powerpoint (now folded under Copilot license I believe) gives slide deigns with shapes etc that are not editable. Thankfully the text remains editable. But if we wnat to ever so slightly modify the suggested design my removing or reshaping some if the shapes ... nopes. Feels like they are worried about humans with taste ripping-off the AI output :D

I’m not sure if the author’s perspective aligns with what I said.

> You don’t need every job to choose you. You just need the one that’s the right fit.

I don’t think anyone expects to pass all the interviews. Seriously, who expects that? The right fit of choices is often limited. You need to deeply understand your weaknesses and strengths to even know what the right fit is. People are usually unaware of their own superpowers. Hard work is the only thing that pays off. Luck comes to those who are prepared.

Same at Amazon. Bezos often talked about "work life harmony" which he liked to say instead of "balance." His reasoning was that balance implies a zero-sum tradeoff in which more dedication to one takes away from the other (a characterization he didn't like).

But simply calling it "harmony" doesn't magically make those tradeoffs go away.

Educated people are the way they are due to a particular personality that they have. They are curious and self driven. Many educated people have no formal education. You cannot teach a personality.

That's not to say other personalities are less worthwhile... It's just that we have emphasized one kind of personality as the ultimate one and then are surprised that -- after maxing out opportunities for those already suited towards that personality -- a saturation point is reached and future effort has marginal gains.

I was just playing with bwrap for isolating npm project actions from the rest of my system.

bwrap --unshare-pid --dev-bind / / --tmpfs /home --bind "$(pwd)" "$(pwd)" bash

it seems to work fairly well? But I just started playing with bwrap this weekend. I do wish bwrap could be told "put the program in this pre-prepared network namespace" because accessing unsecured local dev servers could also be an issue.

> Based on their results...

Do note that they make it very, very, very clear that their results are preliminary, and while they've put a whole lot of work into setting up benchmarking on Linux, they're not at all sure that they've got it all correct.

> ie: very inconsistent frametimes on Nvidia hardware

Yeah, Nvidia on Linux for non-"compute" use has always been a terrible, godawful shitshow. Given Nvidia's recent and fairly-clear disinterest in the "selling graphics cards for people to play video games with" market, [0] I can't imagine things will get consistently better anytime in the near future. [1]

[0] Why sell that silicon to video gamers when you can sell it to cryptominers and -these days- "AI" companies for a much, much, much higher profit?

[1] I mean, it took them how many Windows driver revisions for them to release somewhat-non-garbage drivers for their spanking-new fancy-ass 5000-series cards? And Windows is the only consumer OS that they care about! For video game use, the Linux drivers are gonna be starved for development resources, and -unlike ATi/AMD's drivers- noone in the world can work on them but Nvidia.

That is exactly my point. There is no reason to syntactically distinguish what is semantically non-distinguishable.

The interpretation of a request is up to the server. There is no reason for the client to syntactically distinguish that the request body is for a POST vs QUERY; the request parameters and response have the same shape with the same serialization format.

However, on the other side, a server does control interpretation, so it is responsible for documenting and enforcing how it will interpret. QUERY semantics vs generic POST semantics is a receive/server-side decision and thus should not be a syntactic element of client requests, merely a server description of endpoint semantics (“QUERY endpoint” meaning shorthand for POST endpoint with query semantics).

edit: Thinking about it some more, there is one possible semantic difference which is that a transparent caching layer could use a syntactically different POST (i.e. QUERY) to know it should be allowed to cache the request-response. I do not know enough about caching layers to know how exactly they make fill/eviction choices to know if that is important.

Several ways spring to mind:

* Computer assisted card counting giving running "actual odds" for betting at Blackjack and other games. One person spots and tracks, feeding info to player.

* Wheel physics in roulette .. there's enough infomation in the wheel speed and ball speed prior to close of betting to predict the final octant (eight of a wheel) to a high degree of confidence (eg: if practiced, will improve long term odds to better than expected loss).

I don't see anywhere in HAKMEM where they advocate for the use of unbounded rational numbers.

Do you have any examples of unbounded rational numbers used in a microcontroller program, in a production Forth program, or really in any production user-facing codebase?

I ask specifically for unbounded rational numbers because again bounded rational numbers are effectively equivalent to floating point and fixed denominator rational numbers are equivalent to fixed point.

Which strongly suggests that one reason 4-year degrees have lost value, is the piece of paper has lost value. Because of (most?) people only getting a degree for the paper.

Two improvements then: Degrees that earn the reputation of not being given for anything less than excellence in studies. Where the earned reputation is used both to discourage the non-serious, and enhance the value of the degree.

And of course, bring down the costs. Create a high octane alumni network to match. Foster an opinionated high work ethic, college-as-daycare / party-scene repellent culture. Anything and everything rethought from scratch.

For instance, why are degrees based on years? Why so standardized when neither students or jobs are? Why not a skill chart that can be custom traversed per student - with students expected to move on whenever they choose to, or have a good opportunity. A high percentage of students leaving for good jobs after just one year would be a win.

For just one slice of education, to start.

As with anything complex, start with something small and focused. Like a low population cutting edge practice/research AI school. Start from scratch with the thing that is new, challenging and in high demand.

Then expand into other fast changing, high demand areas. Keep figuring out better ways, keep taking on more, keep reducing costs, as long as all three of those efforts tradeoffs are compatible.

My anecdote isn't quite the same, but it's along the lines of many adults, not just one's parents: While in high school I constantly got the message on how important it was to stay in school and graduate with a high school diploma. Ironically I passed up the chance to have an associate's degree before my 18th birthday, because I absorbed this message so well that I prioritized high school graduation over the A.S.. It was years later (round about the time I finally finished that A.S. at the age of 29) that I realized the message hadn't been meant for me, but for the students who were at risk of dropping out of high school.

I mean we really don't need something to be conscious, would just need it to be accurate, the current models simply aren't built on a framework to be accurate. I think that it's possible, and already being done to effectively instill accuracy. The issue there is that you no longer have the mass marketable general purpose machines that compete with things like Google / Facebook etc for eyeballs, which is where the huge money exists. So you can either sell valuable inference to a target audience and make a few billion. Or you can sell passable slop to 8 billion people and be worth a few trillion.

Unreliable code is incorrect thus undesirable. We limit the risk through review and understanding what we're doing which is not possible when delegating the code generation and review.

Checking output can be done by testing but test code in itself can be unreliable and testing in itself is no correctness guarantee.

The only way reliable code could be produced without human touching it would be using formal specifications, having the LLM write the formal proof at the same time as the code and using some software to validate the proof. The formal specification would have to be written using some kind of programming language, and then we're somewhat back to square one (but with maybe a new higher level language where you only define the specs formally rather than how you implement them).

I'd be most curious to see what type of processing power they would put on such a data center.

For example, the JWST uses a RAD750 ( https://en.wikipedia.org/wiki/RAD750 ) which is based on a PowerPC 750 running at 110 MHz to 200 MHz.

Its successor is the RAD5500 ( https://en.wikipedia.org/wiki/RAD5500 )... which runs at between 66 MHz and 462 MHz.

> The RAD5545 processor employs four RAD5500 cores, achieving performance characteristics of up to 5.6 giga-operations per second (GOPS) and over 3.7 GFLOPS. Power consumption is 20 watts with all peripherals operating.

That's kind of neat... but not exactly data center performance.

Back to the older RAD750...

> The RAD750 system has a price that is comparable to the RAD6000, the latter of which as of 2002 was listed at US$200,000 (equivalent to $349,639 in 2024).

That isn't exactly price performance. Well, unless you're constrained by "it costs millions to replace it."

So... I'm not really sure what devices they'd be putting up there.

The "data centers in space" is much more a "space launch is a hot technology, AI and data centers are a hot technology... put the two together and its too the moon!" (Or at least that's what we tell the investors before we try to spend all their money)

"creating software for free that largely benefits large corporations"

Who cares. The end result of this is that we all get to use amazing software, often for free.

Think of your open source contributions as a gift to all of humanity. I wouldn't get too hung up on the fact that bad people can use it. Hammer makers don't add conditions on who can buy their products, even if it could be used as a murder weapon. Take solace in the fact that your work is creating far more good than evil.

You're increasing the rate of innovation in the world. And we're all grateful for it.

I’ve had a couple of instances where when I describe a requirement, ChatGPT would not list an open source project like n8n and happen to only remember paid alternatives.

It’s an advertiser’s wet dream, being able to slowly creep and manipulate even the most uninterested people into using a product.

And it’s so personalized that ChatGPT may even refuse to tell you about products that are not paying them a cut and this can put out a company entirely out of business, because unlike search engines, the customer might not even learn about your product despite directly asking for it.

I have seen with my own eyes police reports of bike thieves being charged. Bike chop shops have been notably caught and charged in Chicago while I've lived here. I know for absolute fact that bike thieves are charged on a regular basis in Chicago.

I've never seen a report of a bike chop shop in a homeless encampment in Chicago.

I'm not aware of a great number of homeless people who have bikes. I've certainly never seen anyone on a $10k bike on the city streets, regardless of housing status.

The bikes that are stolen are largely stolen by organized rings, and "scrappers" who drive up and down the alleys grabbing any scrap metal not tied down. They're not cutting bikes off racks, but they're taking ones that aren't locked up. I don't know any homeless people that own trucks, so you?

They're not being stolen by homeless people. I mean I'm obviously not saying no homeless person has ever stolen a bike, I'm saying that it's not a significant source of bike theft.

Why do you use homeless as a noun, and not an adjective? Do you also refer to Black people, gay people, or Jewish people this way?

Regardless: bike theft is not a part of the calculation for people to ride a bike, at least here. #1 reason is "riding in traffic is too scary." Reducing bike theft does nothing for those people; it's already not even on their minds when making the decision. (That's your claim, btw, so back it up if you feel like it)

The Outer Space Treaty is very very clear: anything launched into space is the responsibility of the country that launched it. Even if a private company payts for it and operates it, it's still the responsibility of the launching nation. Even if you launch from international waters, your operating company is still registered to a specific country, and the company is made up of citizens of one or more countries, and it is those countries which are responsible for the satellites. Those countries, in fact, have the responsibility to make sure that their citizens follow their laws and regulations. Unless you and your entire team are self-sustaining on that datacenter in outer space (maybe possible a century from now? Maybe not possible ever), you will be hunted down by the proper authorities and held to account for your actions. There is no magic "space is beyond the law" rules; it is just as illegal- and you are just as vulnerable to being arrested- for work done on a datacenter in space as work done on a datacenter on the ground.

1. There was never a push. Functional ecosystems are simply the ones that survived. You can't blame communities that keep the language alive for doing what they want, and not what you want. Without Typelevel and ZIO where would be Scala 3's adoption today?

2. Android has never been even remotely relevant to the space where Scala exists. And no, this was not a missed opportunity for the language. People who think Scala had a shot are completely delusional.

3. I'm personally convinced Spark was the worst thing that happened to the ecosystem as it brought a lot of attention, and indeed, drove adoption, only to result in an incredible amount of shitty code plagued by the worst annoyances in the JVM and big data space. Spark is the biggest open source project in Scala, yet Databricks doesn't seem to give a damn about the language and couldn't even be bothered shipping a Scala 2.13 runtime for years after its release. I sincerely hope Spark moves away from the JVM entirely.

Kotlin is really not any simpler especially with the constant feature creep that results in copying Scala features, only halfbaked. It's even less principled which is the biggest gripe against Scala having too many ways to do the same thing. There's nothing beautiful or practical about a language where people regularly write expression oriented code next to early returns.

It has been. It's been server-side for decades. It's common industry knowledge that the client can't have authority. But server-side anti cheat can't stop aimbots or wall hacks. Client side anti cheat isn't about stopping you from issuing "teleport me to here plz server" commands, it's about stopping people from reading and writing the game's memory/address space.

If you wanted to teleport (and the server was poorly implemented enough to let you) you could just intercept your network packets and add a "teleport plz" message. Real cheats in the wild used to work this way. However a wallhack will need to read the game's memory to know where players are.

What modern anti cheat software does is make it difficult for casual cheats to read/write the game's memory, and force more sophisticated cheats down detectable exploit paths. It's impossible to prevent someone from reading the memory on untrusted hardware, but you can make it difficult and detectable so you can minimize the number of cheaters and maximize the number you detect and ban.

Linux is incompatible with client anti-cheat because there is no security boundary that can't be sidestepped with a custom compiled kernel. Windows is Windows, with known APIs and ways to read process memory that can be monitored. Secure boot means only Microsoft's own built kernels can boot and you now have a meaningful security boundary. Monitor what kernel drivers are loaded and you can make it harder for cheaters to find ways in. Sure you can run in a VM, but you can also detect when it happens.

Sure we can just run with no client side anticheat at all (functionally what Linux always is unless you only run approved, signed kernels and distros with secure boot) but wallhacks and aimbots become trivial to implement. These can only really be detected server side with statistical analysis. I hope you don't ban too many innocent people trying to find all the cheaters that way.
