It does sometimes. South Korea and Japan come to mind.
In fact, Canada doesn’t distinguish between commercial and hobby RPAS operators. Anything over 250g needs at least a Basic license, and anything operating in controlled airspace needs an Advanced license and a filed SFOC. The basic license clarifies where you’re allowed to fly at all.

Soooo these clowns either had no clue at all about the licensing, or just straight up didn’t care. The IR says that Nav Canada (ATC) wasn’t informed of the flight ahead of time, so pretty unlikely that an SFOC was involved.
Most of those other diseases aren’t nearly as contagious. Many of those other diseases we don’t have an easy solution for. None of those other diseases were something that we shut down normal operations for months over. Very notably, we don’t have any diseases in recent memory that had a risk at completely overwhelming our hospital system if not dealt with. Small percent chance it may be, but while it is no spanish flu, Corona is still many times more dangerous than the flu, especially on a wide spread level.

For the vaccines we do have, public schools in most states already require vaccination. Almost every state already requires that children in public schools have the DTaP, IPV, MMR, Varicella, and HepB vaccines to enter Kindergarten. And I would personally have no problems spreading those and the flu shot as a requirement in the same vein as I stated above either.

We are indeed mammals that are walking bags of filth, but we also have minds that we can use to help deal with that fact. We can’t indefinitely contain, and we can’t completely stop transmittable illness. But coronavirus is one of the handful of diseases we now have a tool to deal with, and not taking advantage of that tool to stop needless death and waste is a massive dereliction of duty to one’s fellow man. This isn’t about “not letting anyone die ever from transmittable illness,” this is about a specific dangerous disease that we have invented a tool to help stop.
Probably nothing that will get added to the upstream source but you could make infinite file system modules for things. Userspace FUSE would probably make more sense but this would be a good way to get started.

The general vibe I got when looking in to this is that the Linux kernel has more than enough contributors right now so they make no effort to make it beginner friendly or offer an easy on ramp. IIRC Linus said they have trouble simply reviewing all the changes they receive and if you want to help out Linux, your time would be better used on the non kernel projects.

Things like Gnome or Libre Office would be more than happy to receive help.

You can easily find out yourself. First use a black hole temperature calculator like

https://www.omnicalculator.com/physics/black-hole-temperatur...

or

https://www.vttoth.com/CMS/physics-notes/311-hawking-radiati...

to find the Hawking temperature T_BH of your black hole. Then use the fact that CMB temperature T_CMB is inversely proportional to the cosmological scale factor a(t), where t is time:

https://physics.stackexchange.com/questions/76241/cmbr-tempe...

Set a(t_now) = 1 for convenience; then

T_CMB(t) = T_CMB(t_now) / a(t)

and you want to find the time t when T_BH = T_CMB(t).

That depends on how the scale factor will change over time:

https://en.wikipedia.org/wiki/Scale_factor_(cosmology)

We don't know that, but if we assume for simplicity that dark energy will keep dominating, a(t) will grow exponentially, i.e.

a(t) = a(t) / a(t_now) ~ exp(H_0 * (t - t_now))

where H_0 is Hubble's constant. So

T_CMB(t) = T_CMB(t_now) / a(t) ~ T_CMB(t_now) / exp(H_0 * (t - t_now))

Numbers:

T_CMB(t_now) ~ 2.7 K

H_0 ~ 71 km/s/Mpc ~ 2.3e-18 s^-1

t_now ~ 14 Gyr ~ 3.2e16 s

so, with t expressed in seconds,

T_CMB(t) ~ 2.7 / exp(2.3e-18 * (t - 3.2e16)) K

Setting this equal to T_BH and solving for t, I get

t = 3.2e16 + ln(2.7 / T_BH) / 2.3e-18 s

So let's say you have a solar mass black hole. Then

T_BH ~ 6.16871e-8 K

and so

t ~ 7.7e18 s ~ 2.4e11 years

i.e. 240 billion years (17 times the current age of the universe).

That's actually not a humongous number, thanks to the exponential expansion of a(t). It would take a lot longer with the expansion rate of a matter-dominated universe (exercise for the reader!)

> Those who have previously had an infection with mild to no symptoms should be acknlowedged as a third group in evaluating public health policies (vaccinated, previously infected, and unknown exposure).

Do we know that this is something not currently taken into account? I wouldn't be too surprised if this is already influencing policies. The other thing is if it's being communicated to the public. Also, the data the officials have is most definitely a lower bound since not everyone with COVID was captured by the statistics. Add all that nuance and it may be difficult to send the point across in a way that is understandable to everyone...
How did you end up doing USB with the Arduino? Was it bit banged as well (VUSB)? Is this code available anywhere?
And usually they are paired with a user space tool for even easier interaction. Ideally the driver should expose literally every function and possible action and then the userspace tool has the job of simplifying that down and not supporting very unusual or complicated setups.

You could think of the userspace side as the gui you get with gpu drivers which interacts with a separate kernel space side
The flat earth stuff is astroturfed disinfo seeded to discredit conspiracy narratives as such (ditto Alex Jones who comes from a CIA connected family); the tunnels and kidnapped children are pointing to vast sex trafficking and blackmail networks which operate outside the law (of which Jeffrey Epstein and the legitimately suspicious Pizzagate emails were just one small glimpse); the alien leadership thing is a stand-in for the fact that essentially everyone in our ruling elite is at such a level of sociopathic remove that they almost fancy themselves a different species from the rest of humanity (which they purely view as a resource to be exploited); and the QAnon thing is another astroturfed disinfo campaign which helped to shield Trump from his Epstein connections and get anyone who is clued into this stuff stuck on their computer deciphering 8chan posts and waiting for the cavalry to arrive (and was also very effective in getting normies to scoff at the idea of unaccountable pedophilia by the ruling elite).

I dont feel it is really relevant how many people "can" get the vaccine. First of all, if you can/should get it with your current medical condition is also a fluid thing. One doctor might advice against, another might advice you to get the shot anyway. So this is no clear cut number. There is also the social pressure. So someone might be adviced by their doctor to not get the shot, but they feel so much peer pressure that they decide to take the risk anyway. Ignoring all these issues and claiming their might be a clear cut number just underlines the complete lack of empathy and understanding of how humans work.

The point is that vaccination is still not mandatory, but vaxed people behave towards unvaxed as if it were.

But whats most devastating about all of this is that it made anxious people go fully nuts and break out of their protective shell. I have an axious mother, so I know a bit or two about how anxiety can have bad effects on the people surrounding the anxious. Most of these people were able to "hide" most of their issues and be mostly functioning humans. The pandemic has changed them into little political activists, and has destroyed most of their remaining true social connections. I cant be bothered to spend time if over-anxious people anymore. Life is too short.

I mean in my life of biking - I got two flats in the last two weeks - one, one a single track taking a tight turn - turns out the tube split at a seam, and was faulty. the other one was a faulty tube that literally just exploded around the fill stem... while I was standing next to my bike - almost all my tubes for a long time have been specialized...\\the good thing is most places will replace the tubes.

I have had a few bikes that would pop a tube when just riding off a six-inch curb.

I have had so many flats all on different bikes for different reasons - that my riding behavior changes when I know if I have a spare tube on me or not.

Sorry, maybe I'm ignorant, but I still don't see it.

What I see is: The scope is not a first-class object. You can't "touch" it.

I see variable shadowing. And I think something that's called "dynamic scope"—or maybe it's just references, not sure.

I'm not 100% sure even what "first-class" scope would look like. I don't know any language that claims having it. I have a few ideas but would like to see some more to find out whether this idea make any sense at all. It's not in the ballpark of "first-class comments" and could be even useful. Maybe. But to know that we would need to have some language to play with.

I'm sympathetic to the point being made, but amused that a script and cookie blocker snarled things up early on. And also impressed that they used the actual notification APIs and cookie banner standards with enough fidelity that my extensions hooked it.
Aside from the "assertion" libraries, which I have mixed feelings about, I often use table-driven tests to avoid this. That way each test is generally one line, like `{"1234", 1234}` for testing an Atoi function. Or, I've seen little test helper functions that "fatal" the test on error -- that way it only takes one line instead of three: https://play.golang.org/p/WIALie5fsgd

That's true, it's a while since I did only a little bit of Haskell, but yes. I suppose I didn't think of it because it feels less like 'having to handle' it in Haskell, since that's the norm anyway.

Whereas if you compare Rust to Python, C(++), or Go as I was - having to consume a returned 'result' is more notable.

Very interesting. Must be the first time I have seen JDF.jl talked about in a post. I guess the point about confidence being low is correct, since the format is not yet finalized and stable.

Also, another point is about how fast things can go. For me, developing JDF.jl was also so that I can do things fast! But the poster correctly pointed out that in this use-case, that is not a concern.
Right. Our war for the survival of species is not with mosquitos but with the viruses they can carry. If only we could make them incapable of carrying. But then, viruses probably find other, even more disgusting ways into our bodies.

Thanks for this, it's extremely awesome! Really happy to see others have gone so much farther than I ever did.

I started looking into this myself some years ago. Even started developing a liblinux with process startup code and everything. Abandoned it after I found the kernel itself had an awesome nolibc.h file that was much more practical for my C programming needs:

https://elixir.bootlin.com/linux/latest/source/tools/include...

My code is in a bad state but if you'd like to take a look:

https://github.com/matheusmoreira/liblinux

It's amazing how this really lets you do everything... Want a JIT compiler? Map some executable pages and emit some code. You can statically allocate memory at process startup and use that for bootstrapping code. This lets you implement dynamic memory allocation and even garbage collection in your own language.
Oh god, this sounds like it could be an interview question
Map Diva shuts down due to losing external licensing support
At $DAYJOB we had a Go dependency on a package (maybe pkg/sftp?) that used github.com/pkg/errors to capture a stack trace with the error. These errors were ultimately used in a loop for flow control (maybe testing a lot of files/servers?) where collecting all the stack traces caused a lot of slowdown, heap garbage, and GC pressure.

I used go mod replace to strip the stack trace collection out of pkg/errors, with a fork that does a no-op for that function call, and it was a significant improvement for our use case.
> Why can't we have a compiler with built in system call support? Just add a system_call keyword that inlines Linux system call code using the supplied parameters

It can be implemented as a small function, that first appeared in 4 BSD. It's available in Linux.

$ man syscall

(Unfortunately, this function, lives in glibc. Obviously, though, it doesn't have to. All I'm saying is that this, or a similar function, can be a linkable symbol in some small compiled object file, and not an inline primitive that has to live in the compiler.)

> although FWIW most of the time I don't feel the need to occupy the whole lane.

Yeah, I perhaps should have made it clear that occupying a full lane is something I do probably <2% of the time. Not very often, and for similar reasons to the rest of the comment: I don't really want to have to deal with cars, and if I can stay right and let them by, I will.

I'm in America, so it depends on the road; where we have unprotected bike lanes, then I'm in that & there's passing room, but too often there are "sharrows" where there really isn't a good deal of room for passing. Then it's very situational. (Usually the car taking up part of an oncoming lane as they pass.)
> To me this indicates their immune systems are doing a great job and we should rather avoid teaching them (their perfectly competent immune systems) how they should do it.

This makes no sense from an immunological perspective, and sounds like one of those pseudoscientific ideas that "natural" immunity is somehow stronger than "vaccination" immunity.

A vaccine is nothing more than exposing the immune system to the antigens. If their immune systems are already geared up to fight Covid, they will simply respond to the vaccine as another Covid infection and fight it accordingly.

As for whether there is any benefit, there absolutely is. Multiple exposure events greatly increase the storage of the antibodies in the memory cells of the immune system. This is why most vaccines require at least two shots, and why the CDC is now recommending a third booster shot for some people.

Plenty of studies show that the immunity of people who are vaccinated is stronger than those who were infected naturally (e.g. [1]), and that the immunity of people who have had Covid is significantly more robust after subsequent vaccination (e.g. [2], [3]).
