> I discovered that a bunch of things I thought were reasonably healthy actually caused huge glycemic spikes -- e.g., white bread in the morning, croissants, dried mangos, excessive amount of fruits, etc.

It's baffling that those things are considered healthy in the first place - white bread, pasta, rice, potatoes contain so much starch(which is rapidly broken down into glucose) that their glycemic index is higher than that of table sugar.

Likewise, the entire reason why fruit are tasty is because they're sugar bombs. The absorption is slightly slowed by cell wall digestion, and they have antioxidants, vitamins, etc. But still. It's sugar.

> I also discovered the importance of what you eat for your first meal in the day (either breakfast or lunch), or how to better order what you eat (fibers, fat and protein first, carbs last), light movement after eating reduces 20+ mg/dl, and more.

Having read science on the topic, you're extremely right on botr counts - limiting carbs in the first meal of the day moderates glucose spikes for the entire rest of the day, and moving after high carb meals is critical because muscles uptake glucose independent of insulin signaling, massively reducing the stress on your metabolism.

> But yeah I constantly get confused by when errors can and can not coerce.

It's simple, really. `?` coerces errors if there's an `impl From<InnerError> for OuterError`:

fn outer() -> Result<(), OuterError> { inner()?; Ok(()) }

When OuterError is your own type, you can always add that impl. When it's a library type, you're at its mercy. E.g., the point of anyhow::Error is that it's designed to automatically wrap any other error. To do that, anyhow provides an

impl<E> From<E> for anyhow::Error where E: Error + Send + Sync + 'static

Agreed, nowadays I have to schedule train exchanges to have at least 30 m between them, and even so, I managed to miss connections.

DB is doing their best work for having people reaching out for cars.

While you might get stuck in traffic on the motorway, there are usually workarounds as soon as you get the next exit point, while being stuck on an train stopped in the middle of nowehere with a full train excedding passanger capacity because "pick random excuse", and reservations being optional, isn't really motivating to keep traveling by train.

This is exactly what the author is saying. It is "the idea of APIs in general" that has suddenly become a fad under the guise of MCP, riding the AI wave. And it may well be a very imperfect way to build APIs, but if it eventually becomes the standard to the point where every app has to offer it, it's still "good enough" and would massively improve interoperability all around as a side effect.

Thanks. I appreciate it. Will do if I come across something.

> Also, my partner likely has DID and is struggling with it somewhat. If you have advice or are willing to answer some questions, I'd appreciate talking about it.

Sure. Not sure if you're wanting advice/help for yourself, your partner, or both, but email me at shippage_hn@proton.me if you'd like to talk. I know more about my own particular kind of DID than others, but am willing to talk about what I know of the generalities, too, as well as a bit about my experiences (including getting a diagnosis) if that helps you or your partner.

One of our favourite bits of kit is a twin axle trailer my father built back in the 1970s.

It's got slaved brakes (electrical now, once hydraulic), Hayman-Reese family anti sway bars, uprights and rings on the tow arms to hold gas bottles and spare tyres, and a flat bed.

The smart setup there is removable side and back walls to convert between flat tray and shallow box with sides, and a removable hood with three gull wing doors (so that the tray is a lockable and weather proof space (useful for camping). It's easy to change configuration between the three states.

Our prefered vehicle of choice is a four door family sedan with boot, the trailer can be added for those odd two tonne loads of manure, gravel, straw, sand, etc that get carted about.

Everything else starts getting into dedicated task vehicles - tractors, harveters, chase trucks, etc. The last thing we acquired was an ex military twelve tonne truck with shoulder high tyres on it and enough clearance for pre schoolers to walk under .. it can climb hills, waddle across gullies, and carry 5 tonne of water for fire control (the reason for purchase and fitting).

You're assuming prompting an LLM to behave like X will automatically result in the LLM behaving like X for any X. Some things are out of the LLMs ability: I'm sure you'll get something if your prompt is "You are a 300-IQ nuclear physicist with a doctorate in material science. Describe the design of a cold-fusion reactor", but there is no guarantee the LLM has fidelity to your prompted persona, though it will try to give its very best impression.

I’ve been trying this out. The biggest problem I’m experiencing is that your draws won’t be a perfect multiple of the grid size. Which means you are always going to be left with gaps on the side which are wasted space which could be up to 40mm.

There is kind of a solution to this where you can use non standard grid sizes to perfectly fit your draws, and there are generators which will create the baseplates and bins for you. But you lose the ability to use other people’s models.

Feel like it would have been better if they had picked a smaller grid size so the average wasted space would be smaller.

You don’t know that. There have been studies that have founder lower total system costs with renewables. See studies by Marc Z Jacobsen et. al. for instance.

I know of one study that found fairly low costs with lots of nuclear. But it also assumed continued fossil fuel extraction and a whole lot of CCS, which is not a sustainable solution.

The problem with many analysis that show favourable outcome with nuclear is that they only look at decarbonising electricity. If we look at the big picture, and what’s required to decarbonise everything, you find that we gain a huge amount of flexible load. EVs can charge when electricity is cheap, or even feed energy back into the grid. Switching industry to electricity for heat lets us make heat batteries which can store enormous amount of energy for a very long time. In fact, it may be the only economical way to do it, since they’d end up using a lot of free excess energy from renewables. If they had to use nuclear they’d have to pay the full price of electricity. There’s some proposals to use the heat from nuclear power plants but that has limited applications. You can’t collocate all industry next to nuclear power plants.

There’s a company working on an induction cooktop with integrated batteries, because it may be the only way to replace gas cooktops in some places, as induction ones require a lot of peak power. It’s expensive to upgrade capacity. But if the batteries charge when electricity comes a cheap it’s not an issue. And an induction cooktop has all the components needed for an inverter so it can double as battery backup and save power on your electricity bill.

There are a million solutions like this already in the market or in late stage development. A future where we solve carbon emissions is necessarily a future where the load balancing problem of renewables is solved. Betting that we’ll need nuclear is equivalent with betting that we can’t sustainably solve global climate change (CCS is not a real solution in my book)

In the rural midwest, it's extremely common to see dumpy trailers with one or two 75k new super duties parked outside.

I don't get it at all, and thought "well, maybe they didn't have a choice and needed it for work?" before realizing any old used truck would probably work as well(if not better).

I have to say it's a status symbol, a weird one at that. I'm more in awe of rat rods and fixed up old trucks than brand new ones, YMMV I guess.

Pizza is much more nutritionally complete than you'd think, especially if it has meat(or beans, for some reason), the only real problem is people eat SO MUCH at a time.

People also refuse to understand that juice is basically sugar water with some extra flavor, vitamins, and antioxidants that don't change how unhealthy it is for you.

White rice is basically pure carbs with barely any nutrients.

Fastfood is heavily processed but often contains enough vegetables, meat, etc to not be that bad all things told.

> So large. :)

Consider this: at any moment in history, the prevailing state the art in computing and information systems are characterized has huge, very large, massive, etc. Some years later, it's a portable device with a battery, and we forgive and snicker at those naïve souls that had no idea at the time.

It's still true today. Whatever thing you have in mind: vast software systems running clouds, megawatt powered NVidia GPU clusters, mighty LLMs... given 10-20 years, the equivalent will be an ad subsidized toy you'll impulse purchase on Black Friday.

You're instinct will be to reject this as absurd. Keep in mind, that is the same impulse experienced by those that came before us.

A pigovian tax is not mutually exclusive with those options— in fact it incentivizes them. No need to do market planning for “lab grown meat” or whatever is the central planner’s fancy du jour: set a price and let the market figure it out.

Why have governments pick and choose “winning energy strategies” when you can let the market do it?

Literally how it works in practice with carbon credits today, your assertions to the contrary notwithstanding.

If you know how iPhones work then online research is enough, but if you haven’t played with one it makes sense to use it at the store as research, or even if you’re just curious.

Same for Android, I wouldn’t buy one without testing before, for example.

Also: The Microsoft and Chromebook displays at electronics chain-stores have seriously stepped up their game in the last 10 years or so. Before that it was a shitshow, with keyboards missing keys and the OS crashing on demo devices that would be otherwise perfectly usable machines.
by lloeki | 2025-06-30 06:36:27+00:00
Oh my these devices were everywhere.

I started with a 32 MB Diamond Rio PMP300, so cramped as I transcoded music to 64kbps just to cram an hour in there, but the ability to listen to music without it _ever_ skipping (I was MTBing in the summer and snowboarding in the winter) was invaluable.

https://en.wikipedia.org/wiki/Rio_PMP300

And then upgraded to a 64MB Rio 600

After that it was straight up to a 4GB black iPod Nano gen 1 that I rocked for a loooooong time as it was insanely hardened and durable.

Did some looking around and your claims seem correct. I hope we have another UNCLOS convention soon! Too many bad actors, looks like every major distant-fishing power is polluting / overfishing.

I'd quibble with the PRC being the most sustainable producer, there's more to ecology than just fishing vs no fishing, but it's not a major point. And my biggest concern is with absolute scale (44% of the overall fishing effort makes it an outsize impact no matter what! it's kinda like how the US Army ROE matter more than most country army ROE simply because we're engaged more. Hard to address a global problem without focusing on its largest driver.), although, as you probably feel, the solution for that is a new UNCLOS, not singling out the PRC.

It's not clear what tort would be committed under US law by someone who sold injection-molded parts using the Gridfinity STLs. Patent infringement? No patent has issued. Copyright infringement? Copyright generally only covers expressive elements of works such as the sculpture in question, not functional elements like the "Sega" string that was at issue in Sega vs. Accolade. Trademark? Also doesn't protect functional elements.

Basically, it seems like the inventor purports to be licensing the kinds of exclusive rights to their invention that a patent would grant them, but without actually meeting the legal requirements for receiving a patent.

(I don't know of any other jurisdiction that would give them a cause of action either, but law is diverse enough, and many governments are corrupt enough, that I'm sure there's somewhere in the world they could win a lawsuit.)

Maybe some actual lawyers could chime in on this.

EATX is a pretty standard server motherboard form factor.

It's not even a multiple CPU board...

This is indeed a pretty standard (and weak) ARM server build.

You can get the same CPU M128-30 with 128 3ghz cores for under $800 USD.

You can throw two into a Gigabyte MP72-HB0 and fit it into a full tower case easily.

That'd only cost like $3,200 USD for 256 cores.

RAM is cheap, and that board could take 16 DIMMs.

If you used 16 GB DIMM like OP that's only 256 GB of RAM, in a server, it is not that much... only one gig per core... for like $500 USD.

Maybe for a personal build this seems extravagant but it's nothing special for a server.

Built a gaming desktop for a friend almost 2 years ago; used GPU and CPU (maybe a few others things too), everything's going great. It helps that our local Cragslist offers efficient buyer protection.

Server-side, I also bought used Xeons for an old box and recertified 10TB Exos. No issues there neither.

The HDDs are a bit of a gamble, but for anything else I can only encourage you to buy used!

It sounds like the concern here is that the OP is over-indexing on the use case for a home lab being a place to learn, and not a place to be productive.

> But I don’t consider this a homelab, because I don’t use it as a lab. It sits there, running the ten or so services I self-host for me and my family. When I work on it, it is for regular maintainence, incremental improvement, or to install new services. I do enjoy working on it, and I’ve learned a lot along the way, but these are merely side effects.

> But I think it is interesting that within the set of people who keep servers in their home, there are two subsets (with considerable overlap) whose reasons for doing so are sort of orthogonal. The ‘homelab’ moniker perfectly fits one group, and it would be nice for the self-hosters whose setups are not homelabs to have a cool name too.

If you want to split hairs on naming, then the problem here is that you're imputing an overly strict definition onto the term 'homelab' to not include your use case, complaining that your use case is different to this definition, and then failing to see that the term is generally used loosely enough that it does your use case.

Call it what you will, but from your description of things, you're using the server and associated tech as a homelab.

I'd allow you to call it a "it's not a homelab, but" if you want permission to use a different term... ;P

Saying you can't compare car prices to inflation because cars are in the CPI... We're really doing this?

New cars make up about 4% of the CPI, and used cars around 3%, so together they’re only a small part of the inflation basket. If new car prices doubled tomorrow and nothing else changed, headline inflation would rise by about 4%, but car prices would have increased 92% relative to inflation.

Inflation measures the decline in the value of money over time. If car prices rise significantly more or less than that decline can explain, that’s meaningful. If they don't... that's not.

But I have this dongle, the exact R&D budget one you discuss, and the iPod side by side with the same song loaded (except the iPhone has way higher resolution, as menitoned the iPod is under 256kbps).

The iPod isn't louder, but it has sounds in the music and a breathiness and real, moving sensation that my recent iPhones with lightning or USB to 3.5 adapters haven't had. It's hard to explain unless you listen side by side, and now I sound like an audiophile but I am far from it - the ears just don't lie and the old iPod really had amazing sound.

OP has a homelab.

Normal people don’t have rack-mounted servers in their homes to “self-host” ten services for their family. If you have the skills to do that kind of thing it may very well make sense to do so but you’re basically signing up to do that as a hobby. And that’s fine! Hobbies can be productive! Some people keep chickens as a hobby and feed the eggs to their families. But if you’re running rack mounted servers in your house as a hobby, that’s called a homelab.

There's a load of really good deals on EVs at the moment from what I've seen, I'm guessing cars coming off corporate lease.

From https://www.cinch.co.uk/used-cars/electric-fuel-type?fromYea... there seems to be quite a lot of 2022+ EVs available for ~£10k with relatively low mileages.

So if you've got space for a home charger, those could be pretty good deals.

It will help, but the bootie really is fine-tuned to stingrays, in some ways that might not be obvious. Stingrays strike with limited strength, so we measured tons of stingray strikes and designed to stop that. It won’t do much if you put all your weight onto a nail or something.

But if you want a balance of flexibility and stopping stingray stings, we really are the best. Nobody else is even trying, lol, the other options pretty much do nothing, or are encased in steel and not flexible at all.

> I read your "posers" post as dismissing Etheryte's point and threatening to tar them as some kind of traitor.

> Now it sounds like you're denying that, claiming it was instead some sort of... long-term strategic joke for the benefit of potential future sapient AI?

I thought it was a fairly tame statement. People who pass off AI output as their own/undisclosed are posers. They’re posing as producers, but they are consumers. It’s the same principle behind ghost writing being seen as less prestigious than writing under your own byline or even pen name. It’s about authenticity and transparency. In the context of HN, where generated comments are not allowed, and to accuse others of generated comments is also a bit too meta and should probably be emailed to mods instead, the truth is that the dashes were once a sign of erudition, whereas now they can be seen as phoning it in.

It’s a real mumpsimus and sumpsimus situation, you might say.

> A mumpsimus (/ˈmʌmpsɪməs/ MUHMP-sih-məs) is a "traditional custom obstinately adhered to however unreasonable it may be", or "someone who obstinately clings to an error, bad habit or prejudice, even after the foible has been exposed and the person humiliated; also, any error, bad habit, or prejudice clung to in this fashion". The term originates in the story of a priest using the nonsense word mumpsimus instead of the Latin sumpsimus when giving mass, and refusing to be corrected on the matter. The word may refer to either the speaker or their habit.

> Over time, the contrasting term sumpsimus came into use. To Henry VIII, a sumpsimus is a correction that is unnecessarily litigious or argumentative, but John Burgon used the term for corrections that may be good but are not as important as others.

Hmm, that's pretty strange. Not sure what might be going wrong, could be terminal shenanigans or a genuine bug in ollama.

Of course, double checking the basics would be a good thing to cover: ollama --version should return ollama 0.9.3, and the prompt should be copied and pasted to ensure it's byte-exactly matching.

Maybe you could also try querying the model through its API (localhost:11434/api/generate)? I'll ask a colleague to try and repro on his Mac like last time just to double check. I also tried restarting the model a few times, worked as expected here.

*Update:* getting some serious reproducibility issues across different hardware. A month ago the same experiment with regular quantized gemma3 worked fine between GPU, CPU, and my colleague's Mac, this time the responses differ everywhere (although they are consistent between resets on the same hw). Seems like this model may be more sensitive to hardware differences? I can try generating you a response with regular gemma3 12b qat if you're interested in comparing that.

Large glycemic spikes are are an issue, but the problem is not obesity. Obesity is concerned with calories in and calories out and our current obesity epidemic is largely attributed to the fact that we eat more calories and move less. Most other discussion points are secondary to that fact. Glycemic spikes on the other hand are linked to increased insulin resistance, heightened risk of diabetes, cardiovascular disease and so on. The two are linked, but not the same problem.

I don't convince employers or clients to follow WCAG, I just do it. If they say the link needs to be yellower, I figure out how to make the link look yellower and make it within WCAG.

If they ask for something outside WCAG, I say no, that doesn't meet the standards required and do not ask if they want to respect the standard.

I learned to stop asking permission to use my professional judgement when I went to a boss with an active password/login leak that was risking an important dataset and his response was "if it hasn't leaked, let's just not worry about it and leave it"

What do you know, the next morning he was informed of a leak and I was approved to fix the issue. The leak was not real, of course.
