That's been on the back of my mind but I guess I chalked it up to a bug and didn't think too much about it.

You're right though, this is incredibly dumb design.
- "Environmental epidemiologist Josiah Kephart studies pollution from cooking. In this 2021 photo he measured nitrogen dioxide levels from cooking in his kitchen. At right: A nitrogen dioxide air monitor shows 0.159 parts per million, or 159 parts per billion. That's above the World Health Organization hourly guideline of 106 ppb. Kephart has since replaced the gas stove with an electric one."

That's *barely* above the 1-hour guideline, and as evident in that photo it's an (illegal?) stove with no hood or ventilation. This just reinforces my prior beliefs—that this is a complete non-issue for normal, code-compliant stoves.

(Was NPR unable to take a photo of a NOx meter next to a normal stove?)
Good to see QLab. I’m curious why MaxMSP didn’t make it on there. In college we used it for ‘These Shining Lives’ to create a harmonic, barely perceivable drone over the actors voice fed from the mic. It was sick!
The worst offender of this practice has to be the windows start menu. Even when you fully type the executable name, it can show up below the fold under unrelated results.

> "In my field, we know who those groups are, and we know that work that's done by those groups is not really trustworthy because they have never taken a stance on the side of public health," says Laura Vandenberg, professor of environmental health sciences at University of Massachusetts Amherst.

Notice how she does not criticize their methods or analysis, but rather the conclusions.

Sounds like some groups have a preferred outcome and will not tolerate any dissent and engage in ad-hominem attacks and innuendo (for example see the title of the article).
This looks awesome. I might be missing it somewhere, but what's the minimum required hardware to run something like this locally?
My wife prefers to use curbside pickup for groceries, and orders via the Harris Teeter website. It’s a disaster.

The site search picks up unrelated items, misses others, and so on. I would complain about the inventory management/substitutions too - but since they also have in store shoppers using the same inventory I guess they can’t always be 100% about what’s on the shelf.

You’d think a chain that size could do better, but I doubt they have much incentive. The competition is minimal and not any better.
Long cold winters dimly lit by a flickering CRT.
Author here. I have used Prusas, as well as many other 3D printers. I know how they are distinguished from the rest. The thing is, there really isn't much of a difference between an Ender 3 and a Mk4 that a typical consumer (that is, not an enthusiast) would understand as justifying the bigger price tag. The Mk4 is a better printer, by a long shot, but not by the same factor as the price tag. The Mk4 price completely eliminates Prusa from the entry- to mid-level market which is a big lost opportunity when new enthusiasts are learning on other brands -- and by the time they want to upgrade to a Mk4 price-point, they have much, much better options than Prusa and brand loyalty to someone else. Prusa is not the right choice at any price point anymore and has little to no market relevance left, except maybe among a certain niche of enthusiasts.
Painting never aimed to be photorealistic. Paintings always present a fictional unrealistic visual that tricks the mind into perceiving it as "real".

That is the true measure of an artist's skill - to make the unreal seem real.
I entered into WASM assuming it was simple and minimal but there are a lot of runtime edge cases that are quite surprising. I built an interpreter that passes all the non-SIMD test cases from the official spec. Would be interesting to clean-up the spec to be a real minimal execution only core. There is a real barrier to entry for producing new lightweight implementations.

There is a logic, you type "n" and "news.yc[...].com" comes up, so when you type "ne" then you're presumably (the logic goes) looking for something other than the website that was just presented to you; otherwise you would have chosen that website already rather than continuing to search by adding more letters.

In practice people type what they think will turn up the results "news", say, and don't look at the results until they're finished typing.
People pitching induction always mention that they boil water faster, and it's true. But in my experience with induction, which I admit is not a lot, it seems like that is the only thing it's better at.
Electric imbalance "may" theoretically interfere with your own body biological processes, so people thought being connected to ground to rebalance things a bit would be beneficial. I don't know anything about the reality of it, but, there's Michael Levin's research reviving bioelectricity as a very important layer in tissue level logic (morphogenesis).. so who knows how important it is to ensure a good electrical state.
Good quote:

> Feigning humility, the tech-barons would say they were ‘standing on the shoulders of [their fellow] giants’, when in reality their bloodied scaffolding was made entirely on the backs of nameless, uncredited workers. As we delight in calling bullshit on the creators of our rapidly degrading web platforms, it’s high time we call bullshit on their still-erect creations as well.
I grew up in a very rural area where it was just our group of five or so houses and then nothing in either direction for at least a mile. To get into town was a twenty minute ride by car that involved crossing at least one 55MPH freeway, which of course as a child I was not allowed to do. Later when I moved to the suburbs as a teenager it felt like nothing had changed since I still needed a car to get anywhere.
I've since spent considerable amounts of time in cities and small towns with pre-Eisenhower centers and it's incredible how much you can get done. There were times where I would realize the path I'd taken to do various needed tasks and I'd think to myself that if I had grown up in such a place I would have turned out to be a much better person without as many unhealthy habits. Being able to walk from a bank to a performing arts theatre to a courthouse to a Lebanese restaurant and then to the hospital that overlooked the river so I could watch the boats pass as I waited for a family member ignited an appreciation of density and a hatred of suburbia in me.
Meanwhile it's fifteen minutes of walking to get to a gas station, or thirty minutes of driving to get fast food or groceries from where I live now. I feel bad for my neighbour's kids, honestly. They're trapped like I was at that age.
As soon as someone spells it QT and not Qt, I dial down my valuation of their opinion
Seeing how "pro-gas" comments tend to get greyed-out reminds me very much of the way those who went again the "current thing" were treated during the SARS2 pandemic. Why do many people here have to be so religious about these issues? Why has "supporting the current thing" been turned into something resembling a mantra? I wrote a fairly long comment [1] on my experience with different types of heat sources for cooking. Once I hit the "reply" button I noticed the comment a few levels upstream had been killed [2], probably for bluntly stating the author's preference for gas cookers. This comment section is full of all sorts of hyperbole about hurting children and destroying the planet and such by those who insist on using gas stoves but those comments are left alone - why? Until 2 years ago people could choose their own cooking appliance without the risk of being considered morally bankrupt but now that the current regime has made gas cookers into a "current thing" this has suddenly changed into a choice with decided moral implications.

In other words, it seems like the tactics used by the current regime are successful in that gas stoves have been turned into a "current thing".

Watch Naomi Wu on YouTube. Look beyond her jarring aesthetic, and you’ll get to see the process of building something from idea to prototype and even production in China, specifically Shenzhen.

It genuinely makes me happy that a place like that exists, but sad that there doesn’t seem to be any place like it anywhere else; certainly not in the west.

If you wanted to build a 3D printer from scratch, they have what are functionally large indoor malls selling every component you could possibly need. The people at these shops all know their stuff, and the whole place is just buzzing with genuine makers. And for production it seems as though everyone knows someone with a machine shop and an injection molding setup.

For all of the talk of China’s decline, I wouldn’t count someone out with a place like Shenzhen; the west has nothing like it. Silicon Valley would be so much better socketed into an agile manufacturing juggernaut like that.
I encountered some push back on this in my "code editor from the ground up" post[1]. I think the only reasonable definition of from scratch is:

Does not have domain-specific dependencies.

So a code editor based on ACE or CodeMirror would not be from scratch, obviously, but one that involves writing all of the domain-specific logic would be. Using generic libraries doesn't stop something being from scratch. (In my case Tree-sitter is arguably domain-specific, but an early version did use a hand-coded JavaScript tokeniser in its place.)

I suspect this article isn't accurate about Prusa. It's not clear that they're "floundering" (versus worried). They do have other products (resin printers, supplies like filament). There is a PrusaConnect cloud service and they recently launched a Printables website for sharing models. And probably other stuff I missed.

Launchbar on Mac and Everything on Windows are pretty great, though they solve very different problems.
Most people have no clue because you cannot see or smell it. So people tend to underestimate it. After all, they’ve been doing it for decades, so how bad could it really be? So, you’ll get feelings and intuition as replies if you ask this kind of question, not anything solid.

We are fucking terrible at risk analysis and management.

This is overly simplified.

You could have said "company" and "made in EU" and it wouldn't have been more or less true.

Open source itself is not necessarily a problem but one over many factors that have there pros and cons. And for one struggling company doing open source there are hundred or thousands of struggling companies not doing anything opensource or benefiting from opensource without contributing.
I mean if someone tags pancakes as lentils... that said we had great success by using gpt4-v for product tagging tbh. it really is a game changer.
Honestly, I think Prusa is floundering for the same reason other equipment makers are floundering.

People bought a ton of goods during the pandemic, because they didn't go out much and now people are going out more and the spend is returning to services, meals and entertainment, so people are spending a lot less on devices.

Higher interest rates are also reducing capital investments across the world.

We are just seeing the cyclical change in spending habits over time.
I think for many “open source companies” there’s some underpants gnomes business planning going on:

1. Open source product

2. ???

3. Profit!

Open source isn’t a magical bandaid though it may get you some early traction, the same you can get by having a free plan.

If you develop it appropriately and plan it out, it CAN be successful. But you have to think it out and choose an appropriate license, etc.

Most successful open source companies would have been successful as closed-source; and you rarely can take a closed-source product and make it successful by going open source.

I've worked on products with ALL of these exact issues. The answer is usually that the data isn't annotated well enough, or that there are not enough developer resources to make special case fixes for things 99% of people don't notice or care about (and so are not losing us money, they just annoy us). At the companies I worked for, fixing these problems was not within the remit of the head of product, they were cross-departmental issues and so were in that pernicious category of problems that are highly resistant to change. I assume the reason you think product people are responsible for this is because you aren't a product person, but in my experience those are the people who most desperately want this type of shit to be fixed, because it makes them look like clowns.
I guess you don’t cook? The main function of a stove is to work with your pans/etc to create the heat you desire. Different applications have different requirements. I may use a cast iron pan to store a lot of heat and release it over some time. I may have another where I want to change temperatures in the pan quickly, which is far more common for me.

For example I may use high heat to sear meat and then drop the heat to add butter and herbs and then use the pan drippings to make a sauce which requires intense heating to deglaze and flambé to enhance flavor and then reduce heat quickly to mount the sauce. Copper is the best material for this and it doesn’t work with induction. High quality steel just doesn’t perform.
Sure, but that seems like mostly a question of getting them to a place where that can safely happen. Once it is isolated, let it burn out if it reignites.

Putting it out the first time so that it can be safely moved is important.

> Most of the time, big O is not relevant if you're not writing new algorithm

This attitude is precisely why we have computers thousands of times more powerful than we had in the 90s, and yet they perform the same tasks slower.
My impression is that many of these "open source developers" overestimate the value of their code. There are many amazing projects for which I would pay considerable price, but the long tail of 99% of projects just aren't worth anything in my opinion. It is an interesting exercise though - to imagine how much I would pay for my window manager, gcc or even Vim.

Maybe easier transactions of tiny sums is the real solution? Even if every user paid something trivial like 10 cents a month, it would be a huge revenue stream for popular projects which lack maintenance. Of course, adding monetary incentives opens a whole new can of worms, so maybe the current situation is the best we can do after all. I suspect that many good qualities of open source software come from lack of money involved - there is no telemetry, no dark patterns to keep you using it, no attempts at vendor lock-in.
This a good point... it is an opinion piece and the authors emotional reaction to her family's experience with this system. There are some stats but a more useful artical would be a fact based exploration of the abuses by insurance companies that are enabled from the inherent structure of Medicare Advantage plans.

My own anecdotal experience is how the insurance companies call the elderly (prey on the elderly - abusive practice) to schedule vists from nurses who do nothing more than ask 100's of invasive questions and provide 0 care. They are simply collecting data that is not protected by HIPPA. The data is immensely profitable to the insurance companies to drive the accuracy of their predictive models. The insurance companies then in turn charge CMS for this visit.

The author isn't saying that, they said it's "better than half the value". Something that's let's say 2/3 as good will definitely be obvious.
>The Open Source is about freedom for users not about making life easy for developers or the Company.

That's exactly what open source is about. Open Source was explicitly invented as a more business-friendly version of Free Software, without the whole "freedom" spiel.
Have you seen the gear US firefighters use vs their European counterparts?

Their stuff is ancient, so much so that they need to have "smoke drills" to put their very complicated kit on when they enter a smoke diving situation. This is all because the US helmet is the same shape it was in the 1800s, because tradition or something. They just refused to modernise.

The EU version? four clips attach to the helmet, tighten, done in under 5 seconds.

> They have been struggling as of late, and came under criticism for making the firmware of their Mk4 printer non-free.

One of the biggest reasons I didn't choose a Mk4 was precisely because they moved away from open source.

If you're like me an values open source highly and is looking for a printer, the VORON printers are the way to go. They're DIY printers where you assemble them yourself, so they're not for you if you just want to unbox and press print, but if you want a completely open source printer (from software to hardware) then look no further.

You can even get a cheaper VORON 2.4 or Trident kit for less than the Mk4, and still have some room to replace parts with! And you'll get a much more powerful printer to boot.

Oh, and I avoid the Bambu labs printers because they demand an always on internet connection for you to be able to print with them. The repair-ability is also very poor.
> but they haven't succeeded, for the reasons mentioned

No, I haven't succeeded because I haven't tried yet. However, I am surrounded by open source companies that succeeded.

The comment I responded to obviously reasons theoretically, and confuses some things. I will answer two aspects of it:

> Open Source makes "competing" with an existing company trivial, but with none of the invested costs. So the first mover, the program author, is always at a strategic disadvantage

That's not true. You can't just take some open source program developed by someone else and make money out of it. Let's say I develop open source product P. I offer support and consulting. Let's say you want to compete with me on P. You initially lack the expertise and the notoriety. If Alice and Bob want to get support or consulting for product P, they'd better turn to P experts, which is the company that builds P, me. For you to get customers, you need to prove the world that you are an expert. It takes spending time with the code, and also on marketing. But while you are spending time on this, I am too. You will also fatally need to contribute improvements to the product you are selling to make your customers happy. Actually, if you start contributing, it's a win for both of us and our companies can even be friends.

I'm not making this up. That's actually where I work.

> This is not an accident- it is baked into the very point of open source

So we just countered this. I'm not saying there's no risk. but that's not "by construction".

> There's a reason that very few people in the bazaar actually make decent money. There's a reason the cathedral has treasures.

And now we are confusing development methods, not "open source vs not open source". You don't need to be organized in "bazaar" to build free software. Look how, for instance, SQLite, as open as you could dream, manages very well with their non contribution policy. They are profitable. They have a "first mover advantage".

> These are two pretty distinct concepts, and the (traditional) motives for those two things don't merge terribly well.

Well, they can.

But my biggest argument is that you don't need to believe me. Many "actually open source" companies have succeeded. So, what gives?

I don't need to actually build an open source company to prove my point. Others have been doing well. Maybe me in the future, that's not completely excluded. Thing is, being employed also has advantages.
What do they teach you at university nowadays??? When I was in university studying computer engineering (almost 20y ago) we were taught networking a very thoroughly! Not only every technology involved but even the small details of how everything worked (from Ethernet cable based network using csma/cd to WiFi). We even studied in details ALOHAnet!
I guess you just have to know right people, I have a machinist friend who does small jobs for his friends all the time and some people have milling machines in their garage.
You can probably get machining work done very cheap in the local technical school.
