Blackbody radiation describes an electromagnetic field in thermal equilibrium. Typically, we associate this radiation with a particular source, or boundary; but the blackbody spectrum itself is a Maxwell fact, not a matter fact. Real systems have many degrees of freedom, some matter, some Maxwell. In this particular example, the Maxwell degrees of freedom have a temperature of 3K, while the matter degrees of freedom have a much higher temperature.

Clearly, then, the matter is not in equilibrium with the electromagnetic field. How can this be?

Equilibration is a process that proceeds through a large number of interactions that each exchange energy between two thermal systems (or subsystems). If energy transfer is prevented, for instance by the conservation of mass and momentum, or because no post- states of an appropriate energy are available for one subsystem to evolve into, then the systems may remain far from equilibrium relative to each other.

I’d have to do some homework to verify this, but I think a correct statement is that free massive charged particles don’t gain or lose energy in net from passing radiation; and conversely, they cannot radiate. This is guaranteed by Lorentz symmetry, btw: if you examine a million-kelvin electron in a frame of reference moving alongside it, you’d agree there’s no way it can be radiating: there’s a frame in which it is stationary, and stationary charges don’t radiate. If it isn’t radiating in one inertial frame, it isn’t radiating in any inertial frame.

Only during collisions between charged particles is there a possibility for the matter and Maxwell degrees of freedom to exchange energy: and these are very rare in tenuous plasma. (We would call these “three-body interactions” because the photon counts as one.)

[edit to add]
Now one might object that charged particles are always interacting, because their fields fall off like 1/r^2; they don’t just end. Indeed! But one of the effects of being in a plasma is that charges are “screened”. You can think of that as meaning the net effect of many-body interactions can be described as altering the “effective” field of each particle to fall off much faster, like e^-r.
You can if you order a Chinese splitter. All it does is split your lightning into two ports: the charging pins and all the other pins. Because the sound is sent digitally from your lighting port to the splitter, then digitally again to the lightning-to-3.5mm dongle you have no quality loss from a subpar splitter chip.

Edit: to be clear, this shouldn’t be needed, but alas, we cannot steer Apple.
Treating children for worms yields long-term benefits, says new study
That'll show 'em!
They went for a single model, which is an in between. 3a was 5.6", 3a XL was 6", the 4a is 5.8" They also got rid of storage SKUs too, there's now only a single 128GB version. Even the color too, down to a single color instead of 3.

Maybe it's due to COVID-19 and supply chain issues, but they're getting rid of all variations and focusing on delivering a single version.
What I have read indicated that it was a violation that was missed:

> During the original design and certification of Boeing’s 737 MAX, company engineers didn’t notice that the electrical wiring doesn’t meet federal aviation regulations for safe wire separation. And the Federal Aviation Administration (FAA) failed to detect Boeing’s miss.

https://www.seattletimes.com/business/boeing-aerospace/faa-f...

Boeing did try making the argument that since their 737-NG planes were produced prior to that rule, and they're safe, that the MAX shouldn't either. But it was part of the regulations when the MAX was designed.
Came here for this - I knew there must be an analytical solution involving Markov chains.

"Since there are indications that wearing masks does give you some protection and does give significant protection to those around you..."

This is precisely what I'm trying to find evidence of. So far, I've clicked through to one summary of the research, followed by three papers linked in there, which supposedly support the claim, and found that there is almost no support for those claims.

And as I already said above, I do wear one.

Edited to add: Also, I've been reading more and more articles questioning the claim that Coronavirus is mostly limited to the larger droplets.
The insulation would likely be some type of spray-on foam over aluminum tanks, so not a lot of weight penalty there.

Cooling likely wouldn't be done, I assume any excess hydrogen boil-off that couldn't be burned immediately would be allowed to escape through an overpressure vent. (So ideally top it up right before taking off. There could still be a problem if the plane needs to queue a very long time for a congested runway.)

PP-YOLO Surpasses YOLOv4 – State-of-the-art object detection techniques
I don't think the iPhone HEIF is 14/16bit. And I'm not sure a single shot on a sensor that small has that much dynamic range anyway, so you'd still want HDR+ style multiple exposures. Just wish the end result wasn't stored 8bit so you have more freedom to change the exposure/shadows/highlights after the shot is saved
> they can lock out the bad one as an input to the MCAS

The 737 MAX didn't support that as delivered.

Even with the warning (which some US airlines paid for), you couldn't "lock out the bad one" even assuming you knew which one that was (you don't). All you could do is disable the electronic horizontal stabilizer completely, so that MCAS couldn't command it into a dangerous and unrecoverable state.

MCAS has been fixed, in the sense that it won't command continuously bad trim inputs until the aircraft is unrecoverable when bad AOA data is provided, but ultimately the aircraft either needs to be designed around trustworthy AOA data (i.e. triple) or you untrustworthy (i.e. double, even with the warning). Half measures are exactly how we got to this point, with two crashes.

Both answers are actually acceptable. A lot of completely safe aircraft have untrustworthy AOA inputs, the key there though is that automated systems are designed around that assumption. MCAS had too much flight authority to be linked to untrustworthy inputs.

See others' answers about the equilibrium required for BB radiation -- maybe also the density of this matter is not high enough to be a normal BB radiator, or "thermalized"?

Anyway, the density of this matter could be so low that the amount of energy being emitted/received here per unit area (e.g. per square degree of sky) is too low to be detected by equipment. Also note that the radiation is getting redshifted at every distance, so the signal would be further "smeared" and weakened compared to if it were all at a narrow frequency range.
I don't think it makes any sense for a person engaging in one risky activity to feel obligated to engage in a second one.

Do you also think it's wrong if someone wants to eat a healthy dinner after having an unhealthy breakfast and lunch?
Graphing the differences in the pieces on a LEGO panel was very clever!

This article also reminded me to "zoom out" on a design. If it's super confusing at that level, it probably still needs work. The ventilator example suffers from this a bit. It is really nice to have the instructions inline with the dials, but the visual design makes it look more complicated. If you imagined the LEGO-version, it would have more symmetrical color blocks and alignment. I don't mean to pick on them too harshly, sounds like it was made and distributed in record time!
> Sometimes you don't want to show others data as it is being edited, think product data for an online story.

In modern CMS workflows (used by e.g. newspapers), the software will auto-save draft versions; while you then explicitly publish particular versions (or, more likely, submit particular versions for the next stage of the pipeline, e.g. editing) by changing your latest version's state in a drop-down.

This process really has no analogy with saving per se. It's more like tagging a commit.
> JSON is widely used.

Not sure I understand how JSON fits into the discussion tbh. Our users don’t decide which format they receive drawings in. They need to handle all the major formats. Our users can’t ask their customer “can you send me a dxf/step/ifc/... instead of the dwg you sent me?”, sadly it’s just not possible.
IDK, I’ve seen some very incredibly lights on what look to be modern, unmodified vehicles.

Since you don’t seem to have any statistics to go with your assertion that most of the bright lights are because of aftermarket installations, I have no reason to believe it over any of the alternatives such as:

- Lights being too bright from the factory (because some regulations don’t specific peak lumens).
- Lights being misaligned from the factory (a small amount makes a big difference).

Or the most likely to me:

- People carrying a significant amount of weight in the back of the vehicle. This would be most commonly seen on trucks and SUVs, but could also be a smaller car with something heavy in the trunk.

Not sure on the authority of this resource, but they list the most common reason headlights would need to be adjusted as:

> In most cases, headlights simply slip out of adjustment over time. In fact, most headlights will need to be adjusted every few years. Here are a couple of reasons your headlights may be pointed at the sky:
>
> Reason 1: Too much weight. One of the most common reasons that headlights are not shining on the road or are blinding oncoming drivers is due to excess weight in the trunk or cargo area. This will push down the rear of the vehicle enough to tilt the front of it up, along with the light beams.

In a case like this a ticket or warning from a traffic cop would likely be sufficient for someone to adjust their headlamps, but you instead jump to jailing someone? That’s a bit extreme.

I'm pretty sure Iranians can count dead people, and they absolutely count as "industrial world." I've known a few Iranians in my day, and they didn't strike me as particularly incapable of things like counting the dead. People could do this before computers and heavy industry. You tend to notice dead bodies; they smell bad.

That's really all you need; a historical time series of dead people. Frankly, the US, Europe; it's the only data for Covid I look at any more because the rest of it is politicized and site specific, and a changing process over time.

At 350$, if you use it for 3 years (which is the minimum number of years it gets updates for), you would basically be paying more for your Netflix subscription than for your phone. And I'd wager most people use their phone much more than they do their Netflix.
So you are agreeing to US adopting same practices as China. Good. Probably what China wants as well.
Thank you very much for the detailed description of the process behind design; I appreciate that you put it in concrete terms and actionable steps.

I'm specifically building an internal tool for service-requesting, thus the users will be from our own company and there is no competition to speak of. Most of the points you listed still apply, of course, but I'd still like to ask if you have any tips that could help me in this concrete situation.

And also, where would you recommend me to look for inspiration? (apart from "just look around on the web") Nowadays I often look at tailwindui.com to get an idea how some particular component could look like, but there must be something better. Awwwards and dribbble (at least at first sight) are too landing-page oriented — not something I could use in an internal service.

I've had many Nexus models and honestly they weren't any better. But I saw it as a trade-off. I agreed to do the beta testing in exchange of good specs for the price. Hardware QA was also shit but the customer service would send you a new device before you'd return yours, almost no questions asked.

I've heard it's gotten worse with the Pixels even though they're much more expensive. And some models have shown insane bugs/defects, for instance calling issues (!) with the Pixel 3.

lol, UFCS was discussed in C++ before Rust even existed. Here's a paper from 2003 that mentions it: https://www.stroustrup.com/N1522-concept-criteria.pdf

the committee is pretty much against it so it won't get into "C++" though. but who cares, clang as a compiler already targets more platforms and has more eyeballs and development than most other languages anyways.

I would rather be identified by what I use the tool to accomplish, not by the particular (age) tool.

The risk/reward of car travel in 1996 was OK with me at the time... It's great that cities are considering banning vehicles over emissions - I bike, walk, bus, or take the electric car (recently bought a Leaf) when just moving myself. The van is for moving big stuff and/or longer rural trips; it's an example of a tool that still serves my purposes and is not something that I want to be identified by.

I'm looking for a role as a software development manager. My background includes building web apps and high-traffic websites as a full-stack dev, so a SaaS company would probably be the best fit. Because of my time spent as an SRE, I have a strong focus in making sure systems are reliable and maintainable, to minimize the time spent putting out fires.

I like solving people's problems, which sometimes means asking "why" to figure out the real problem instead of just fixing symptoms. I'm good at iteratively developing processes, so I would bring a lot to the table in a company that needs help bringing order to chaos.
I wish I had something like that, but I never got into PowerPC Macs, I bought into the ecosystem with I think the second generation of plastic Intel Macbooks (which, looking back, were quite terrible), and while there's still an early 90s Schneider home computer somewhere in the basement, I fear it won't work anymore and not be any joy to use anyway; that thing was incredibly primitive. It took almost a whole afternoon for my dad to make it play a really simple child's tune for little me. I don't think I appreciated it properly at the time.

I wonder if a Pi 4 would have the horsepower to run a PowerPC emulator with OS 9 properly. If it did, the biggest difficulty might be finding a decent small-ish external screen.
Rent control. It makes more sense to keep the place vacant than to reduce the base rent, which could take decades to make up.
Oh I see. But putting it in the charger all the time just makes the battery die more quickly, right? Though I see the value now if you don't care about that.
Would you mind going into a bit more detail about the systems that work for you? Is it just like a checklist at the beginning of each day or?
Oh wow, this is almost exactly the sort of computer I keep wishing would be made. Design wise it seems like a "spiritual successor" to this SPARC laptop I have [0], with a mechanical keyboard and trackball, except significantly better in every way. I'm gonna have to find a way to fit this in my budget ;)

Only thing that concerns me, is I've had pretty bad luck with an older i.MX6 SoC and its Vivante GPU. The etnaviv project is incredible but I've never gotten it to work reliably. Apparently this specific quad-core i.MX6 is known for having weird MMU/memory problems with etnaviv, but I'm curious -- how much custom software does this need over "stock" Debian to get a reasonably smooth and reliable desktop?

QtWidgets works really hard to try and remain native (both by reusing the platform window pointers, and mimicking style and functionality). That for me is worth it. While the article constantly complains about dev tooling size, a reasonable complaint, my DLLs I ship w/ my Qt program are just 20MB (so I'd suspect a similar size increase to a single binary were I to statically link). If I didn't care about native look and feel I might have gone GTK3 (absent from the comparison here).

Having said that, the other issues concerning Qt may be valid, but for a code-only set of widgets, they work for me. For these kinds of comparisons to have value, you have to list the pros and cons of all things, not just the pros of what you like and cons of what you don't.

Interesting read, but supposedly when we're talking about changes in social mobility we really care about the change in the percentage of people that are richer than their parents? Indeed towards the end of the article the author says:

> There is one study of progress over time that follows parents and children that is gloomy and that is “The Fading American Dream: Trends in Absolute Mobility Since 1940” by Raj Chetty, David Grusky, Maximilian Hell, Nathaniel Hendren, Robert Manduca, Jimmy Narang (Chetty et al) They find that if you were born in 1940, you had a 92% chance of surpassing your parents income. But if you were born in 1984, the number is a depressing 50%. Chetty et al control for age — this is for parents and children when they are both 30. This does suggest that the American dream is dead or at least dying — half of the children do better than their parents but half do worse, suggesting no progress over time.

The author then says that we should measure income differently by using a non-standard measure of inflation. But if we had just used that non-standard measure on the wage data of Piketty et al., we would've arrived at the same conclusion anyway?
