> This control board uses the same microcontroller GPIO pin to both drive segment A of the LED display and sense the door switch.

Is it necessary to be so skimpy with a safety feature?


Later sections of the article detail how there are multiple different safety features integrated to guard against various different failures triggering the magnetron with the door open.

The post explains how the microcontroller sensing the door switch is not a safety feature.

"If you need subsidies in order to live off art, you don't live off art but live off the state".

As part time artist I see many problems with these schemes:

- Decoupled from people's actual appreciation of the art being done: I feel better when I know people voluntarily gave up their hard-earned money for what I do. - Monopoly-style "winner takes all". The people who benefit from this are the ones already in a position to ask for the benefit. - No one bites the hand that feeds then. That will form a body of "artists" subservient to the state.

The human problem is that no artist is willing to acknowledge that the public is not willing to spend money on their product.


The obvious conclusion is that artists should make the art that the wealthy want and are willing to pay for.

And in hard economic times artists ought to turn to gleaning.


Thats whats happened in Norway, and even worse they gave the artists the decision making process of handing out grants leading to them self dealing or dealing to their friends.

Oh, wow. The absolute worst thing that could happen to this sort of program would be for artists to make the decisions about who qualifies.

Must feel pretty good when rich people get into a bidding war over your product!

I have a hobby and I don't get compensated for it (quite the opposite). It's not making art, but if art were my calling I could quite easily see myself making it without any hope of monetary reward. There are plenty of people who have the same hobby as me and don't have a job -- they pursue it as is it's a job, though most are not paid either. I view that as some combination of privilege and laziness.

If there's any problem here it's that people don't have enough time to pursue hobbies. I only have enough time because I work from home (no time wasted commuting). Perhaps the government should focus on where we as a society waste people's time and energy such that they have none left over for hobbies.


> Society has not disintegrated.

Has art improved in any measure?


Yes! Can you prove me wrong?

That is one of my problems with systemd: it has way to much "magic" built in. SysVinit/OpenRC and related are easy to understand and debug: they only do what's in the scripts.


The 3d-printer of software: get a custom part quickly and cheaply, even if not suitable for mass production.


I think this is a great analogy


They "conveyed" the software, according to GPL wording. They violation is towards the original software's authors.


That’s true, but the contract thing is also separately true. The TV came with a notice stating that it used GPL’d software and offering to convey the source to anyone who wrote them. That’s a valid contract, which the SFC tried to act on. Vizio rebuffed them, so one of the issues before the court is a literal contract violation.


With master gone, it's time to get rid of the man-pages, which were invented to mansplain commands by bearded men in the 70s.


I eagerly await that change.

However, "man" originally means "people" as in "mankind", or "human". It's only recently (c 1400) that it replaced "wer" ("wif" being the feminine noun) as meaning males (or mid 20th century for becoming an exclamation).


In addition, this is entirely pointless, because man is short for manual, which comes from manus, the hand, because it is something, that you should keep at hand.


The problem with asbestos is that, due to its structure, it keeps breaking in the longitudinal direction, making thinner and thinner until it is the size of chromosomes. Physical interference with DNA is how it causes cancer.

My understanding is that basalt fibers seem to be glassy, not crystalline, so the breaking does not happen.


The source material is crystalline, but it becomes somewhat glassy during the fiber manufacture, when it is cooled too fast to crystallize completely.

Asbestos is made from some silicates (pyroxenes or amphiboles) which contain long covalent chains of silicon and oxygen atoms, which are more likely to separate than to break transversally.

Basalt also contains pyroxenes and amphiboles, but they are mixed with other kinds of silicates and they also have a different chemical composition than those of asbestos, so as far as it is known for now the probability of breaking into very thin fibers is very low for basalt fibers.

It is plausible that basalt fibers should be safer, because unlike with asbestos, which is made from rather rare minerals, basalt covers a large fraction of the surface of the Earth, so if basalt were dangerous erosion should have made harmful basalt fragments abundant in the environment.


Is it correct so think that the least crystalline it ends up being, the more tensile strength it has ?


No, the greater tensile strength of basalt fiber versus glass fiber is due to it being partly crystallized, similarly to the greater strength of glass-ceramic vessels (i.e. which are made from a glass for easier formability, but then they are crystallized by a heat treatment) versus glass vessels.

While there are glasses much stronger than ordinary glass, there are a lot of even stronger ceramics, which are (poly-)crystalline.

Glasses have many advantages vs. other materials, e.g. easy processing for making any shapes, including fibers, no porosity, chemical resistance, optical transparency and so on, but strength is not one of them.

The glass content of the basalt fibers is useful for allowing them to be drawn into fibers, by being soft enough for this even at a temperature under the melting point of the basalt.


> Physical interference with DNA is how it causes cancer.

Is there a reference for that, because it's curious. (As in I really hope you have a reference to read.)

I'd thought I had seen that repeated scarring (from being not broken down) upregulates cellular replacement rate, or concomitant inflammation were suspect.

super interesting. thanks for following up, because i'll read it!


Basalt also interacts with DNA, hence some origin of life theories try to feature it


My bartender told me the other night that as long as I have 2 cups of black coffee and some red meat before drinking, it will coat my liver and prevent cirrhosis. I'm wondering if I should have him check out the mole on my arm, just to put my mind at ease. He would probably volunteer to be an experimental subject to prove this glass theory.


Having a separation between the "pure language" and the library is a requirement if you want to have a language that can be used for low-level components, like kernels or bare-bones software.

I don't think this is possible in a language that needs a runtime, like Go.


That was the first product released >10 years ago at my previous job [1]. The idea did not quite catch on, though, and the product was repurposed (successfully) as an OEM charger. There is not a lot of power available on street lamps and charging at 3.6kW is kind of slow. Consider that with almost the same hardware (especially the same expensive parts) and three-phase current, 22kW are possible.

It might turn out differently in the US, but it is hardly a new idea.

3.6 kW gives between 10 and 20 km of range per hour of charging depending on the vehicle you have. This is plenty fast enough for overnight charging.


Yes I've never bothered with a higher output for my own home charger, a standard outlet is plenty if you're parked every night
