Hi there!

FemtoStar Project lead here. We're very aware of how impressive of a system Starlink is, and our intention is anything but to ignore it.

The key point, to that FAQ item, is that FemtoStar and Starlink are not directly comparable products because FemtoStar is MSS and Starlink is FSS, which results in a swath of differences beyond the basic "Starlink is faster".

FemtoStar, as well as offerings like Inmarsat BGAN, Iridium Certus, etc are MSS offerings. If you want to compare MSS, compare between these.

Starlink, as well as offerings like HughesNet and other VSAT providers, are FSS offerings. If you want to compare FSS, compare between these.

If you compare FemtoStar to Starlink on speed alone, Starlink wins just as HughesNet wins if you compare it to BGAN on speed alone. That doesn't mean any of these are bad products, just that different classes of terminal are for different jobs. Antenna size is directly related to attainable data rate, and just as scaling up the FemtoStar terminal would get you faster speeds on FemtoStar, scaling down the Starlink terminal would get you slower speeds on Starlink. There's a reason MSS companies usually offer a range of terminal sizes - not everyone needs the same combination of performance and portability. Starlink may indeed introduce a smaller, lower-speed terminal in order to enter the MSS market (though they do not currently have MSS licenses in any country we are aware of, only FSS and FSS with ESIM licenses), but Starlink as it stands is FSS.

To your second point, inter-satelite links (ISLs) and point-to-point connectivity are not the same thing. Starlink has ISLs on a handful of satellites (in-plane links only, no crosslinks yet) which it plans to use for point-to-point connectivity, but this is not part of their consumer offering. FemtoStar actually doesn't have ISLs at all, but it will support point-to-point connections for all users on all terminals as the standard service.

In Starlink's case, yes, their network uses the user's location in order to do that. In FemtoStar's case, however, a high degree of geolocation-resistance is actually attainable using a combination of terminal-side geolocation mitigations and larger-than-usual transmit beams on the satellite. The terminal provides a very rough point for beam pointing on the satellite, but the provided point is randomly selected and can be hundreds of kilometers from where the user actually is.

Please let us know if you have any more questions!

It's a country road. There are no sidewalks. So no. It's not something you walk along. (And hardly unique to the US.) The ESRI categorization is ex-urban. The basic point is that the census bureau categorizes areas as urban unless they're really rural, as in small and pretty far from an urban center.
Oh this is going to be fun.

I see you're referring to the "Metro area of London". when referring to that size. The size of London proper is 1,572 km2 (Wikipedia, as well)

So now, the fun question is "what area is the camera count referring to?"

Further, the quantity of cameras matters less than the areas the cameras can see that is covered.

Even further-further is how easy it is for the government to acquire the footage off those cameras.

I'm not sure I understand. A large company has a whole team and a small start-up has one person assign the task? That sounds entirely reasonable.
I'm not sure if I'm a dinosaur or not, but for "old fashioned" HTML+CSS+JS static builds I've rolled my own Gulp setup that does what I tell it to. It's an investment of a couple days I'm sure, but have yet to just try Webpack to see how well it works for that purpose too, can anyone else comment?

Being stuck in Visual Studio 2019 right now for other reasons, I've been using some of it's "Lib Man" client-side library installers to help reduce the amount of gulp required too. Basically all your vendor/polyfill "lib" can just be brought and managed with a couple of clicks.

It's because the stronger the forces and the higher the velocity in a cell of the simulation, the more iterations the numerical integrator needs to perform to maintain acceptable accuracy. It's obvious, really. ;)

Also the universe isn't actually expanding and the red shift we see in distant stars is just a numerical error due to the enormous number of steps between here and there. :)

About your edit:

> "ISO C does not say anything about write(2), hence using write(2) is undefined behavior according to the C standard", which seems like a rather tautological and useless statement to me.

That is actually not so useless at all: if you try to compile and link a program that declares and calls a function but does not define it, you will typically get a linker error about an unresolved reference. If the name matches a non-ISO C library function, however, the implementation cannot know whether your program is in error or whether you want to use that library function, and will usually accept it. For this reason, the C standard does actually make it clear that using write(2) is UB to make it clear that implementations are not required to diagnose that as an error.

What I don't understand... the UK was already doing challenge studies (intentionally infecting consenting volunteers).

Why didn't they make one with masks? Really can't be that hard to take a known infected person, sit them on a chair, arrange 100 people around them for a few hours with masks applied in a checkerboard pattern, and observe the results.

This is usually out of question for ethical reasons, but they already decided that that wasn't an obstacle, so why not (also) do a study on this?

(Or rather, arrange 10x 10 people, in 5 rounds putting a mask on the infected person.)
>" The balance of seats in the Senate "

Do you mean the House? I think the Senate would still have 2 senators per state, and state-level electoral results are unlikely to change if an alienated minority from one state secedes, in favor of joining a more (politically) similar state.
Hahaha I see, thanks. It reminds me of defenestration!
Yup. Radio silence on that front for years. But it’s not just them, it’s many others on this new trendy virtue signaling dance until they later do something incompatible with their public statements and ignore it once again when called out.

Perhaps Coinbase and Basecamp are the clever ones to resist accidentally signing up to the lifetime of demands from extremely politically charged activists that thrive from catching out employees and cancelling them for wrongthink and screaming about their dramas all over Twitter.

I don't see how suggesting someone would rather not have a disability is "gross". These kinds of overreactions don't help the situation. Try arguing a point rather than coming from a place of emotion.
Elections for senators and governors are, or at least are more valid: no electoral college and no gerrymandering of districts. Of course, vote suppression is still there, and simply lying, but it's an improvement.
What I get out this is that "decimal numbers divisible by 7" is a regular language (can be recognized by a deterministic finite automaton). Is there a general procedure to construct such a graph for a arbitrary (base and) divisor?

You logging into your computer unlocks your keyring, which unlocks the secret your browser uses to encrypt things like passwords....

However looking at my keyring on Linux, I see secrets for Chrome, I do not see secrets for firefox... Which I find extremely surprising and disappointing...
> The obvious intention is that the compiler ignores overflow and lets the processor architecture make the decision.

If that were the case, wouldn't signed overflow be implementation-defined or unspecified behavior, instead of undefined behavior?

> Assuming that overflow doesn't happen is assuming something false.

It's "false" in the same way that assuming two restrict pointers don't alias is "false". It may not be universally true for every single program and/or execution, but the compiler is explicitly allowed to disregard cases where the assumption may not hold (i.e., the compiler is allowed to "ignor[e] the situation completely").

And again, the compiler is allowed to make this assumption because undefined behavior has no defined semantics. If the compiler assumes that no undefined behavior occurs, and undefined behavior does occur, whatever happens at that point is still conforming, since the Standard says that it imposes no requirements on said program.

> it doesn't "optimize" anything.

...But it does allow for optimizations? For example, assuming signed overflow can allow the compiler to unroll/vectorize loops when the loop index is not the size of a machine word [0]. Godbolt example at [1].

Ventilation could also be a factor. You're more likely to open the window when the air outside is pleasant.
We've tried a handful of things: Rec Room, Population One, Spatial, Echo VR, Beat Saber, Bigscreen, and Immersed.

The last few weeks we've been playing Population One together since they have a very simple 6-digit-room-code way of creating private lobbies that can support > 8 people. They also have great team/voice configuration settings where you can set up who can talk to who. I worry a little about gun games and inclusivity, but it's the only app that's consistently allowed the 8 of us to get together without spending 30 minutes troubleshooting. Probably this is in part because they just avoid the quirks of the Quest party system altogether and use their own private lobby system.

Echo VR's private lobby system never worked for us (we were only able to get 2-3 people in the same private lobby at the same time).

Rec Room is nice and easy for new VR people, but when we've gone into the minigames it seems to split us up into different teams, with different team chats, and we can't talk to eachother anymore. We also couldn't figure out if it's possible to make private games. But this is one I'd like to investigate more.

Beat Saber works pretty well but maxes out at 5 people.

Spatial works well for meetings, but if you're just looking to hang out it gets kinda boring.

Immersed is super cool for coworking, but I think it costs monthly money if you want to cowork IIRC.
If the universe as we know it is a simulation, we know absolutely nothing.
They are providing an example of another situation that has been difficult as the two parties can take polar opposite positions on (1) whether something is an issue, and (2) how to solve that issue, often without understanding each other's view point and how they came to that view point.

I see the outside reference fitting here.
A big warning that should probably come with all barefoot / no-padding shoes is: walking habits that are normal with padded shoes can cause pain and damage. And feet heal slowly, so that can take a long time to recover from.

Shift your weight forward, watch some barefoot running / walking videos, and switch shoe-styles SLOWLY. Going out for a moderate run immediately might give you heel bruises, micro-fractures, and pain for a month or more. Knee and hip pain/injuries are also somewhat common, repeated jarring impacts on joints adds up FAST.

Obviously this all depends on your normal gait now. Some people are pretty close to it by default. Some are extremely far. Be careful and you'll be fine. But it'll take a while to re-train walking habits to the point that they're subconscious.

---

That said, I'm a convert. I grew up on the edge of needing custom arch inserts. Within a couple months of going barefoot-style I stopped needing them, and in less than a year I basically stopped having foot pain at all, and continuing for ~15 years now. (it did take ~2 years to be able to walk around comfortably on concrete all day though, prior to that I'd be a bit sore after N hours)
In terms of large customers, yes, community projects like that are an option, but in a lot of cases we expect our customers to be individuals simply purchasing a terminal for their own use. We've had plenty of individuals express interest in using it - it probably wouldn't be useful to start just listing off names but if you'd like to join the FemtoStar Matrix room you'll find plenty of people very interested in it (though, in fairness, being interested in it is why you would join the Matrix room to begin with).

We have found that the idea of 100%-FOSS, privacy-respecting, low-cost, medium-speed internet access even in the middle of nowhere, plus an open platform for custom services is appealing to a lot of people.

You can write distributed coroutines in assembly with enough programming discipline. What is interesting in a language is not what it lets you do, it's what it prevents you from doing.

tl;dr- There wasn't really a conundrum to explain related to mask-effectiveness at different levels. Rather, it's more like a lack of good data, as prior studies being cited were ridiculously weak.

---

This seems like a largely helpful characterization.

However:

> So they are left with a conundrum that places which use surgical masks seem to be better off, whereas randomized control studies of surgical masks show little to no benefit. This is what they try to explain with a mathematical model.

There wasn't really a conundrum. When the study writes:

> Moreover, randomized clinical trials show inconsistent or inconclusive results, with some studies reporting only a marginal benefit or no effect of mask use (5, 6).

, the two studies they cite with inconclusive data are ridiculously weak.

The first one (their "5") is [https://academic.oup.com/jid/article/201/4/491/861190]. This was published in 2010, with data from 2006-to-2007, for "influenza-like illness" (not SARS-CoV-2, nor even influenza (explained below)). Apparently they asked students living in the dorms to do certain behaviors for weeks at a time. They concluded:

> Conclusions: These findings suggest that face masks and hand hygiene may reduce respiratory illnesses in shared living settings and mitigate the impact of the influenza A(H1N1) pandemic.

And if that sounds inconclusive, yeah.. their study was ridiculously under-powered. In fact:

> This study has several limitations. First, influenza incidence was low, so it is likely that most ILI cases were not associated with influenza infection, even though the study was conducted during the influenza season.

So not only were they not writing about COVID, apparently the authors argue that most of the cases probably weren't even influenza. There're other huge problems with this study too.

The second one (their "6") is [https://pubmed.ncbi.nlm.nih.gov/33205991/]. This study assigned subjects a recommendation to wear masks -- presumably some who were recommended to wear masks didn't, while some who weren't recommended to wear masks did.

Even then, their statistical analysis was very noisy:

> Although the difference observed was not statistically significant, the 95% CIs are compatible with a 46% reduction to a 23% increase in infection.

And their stated limitations:

> Limitation: Inconclusive results, missing data, variable adherence, patient-reported findings on home tests, no blinding, and no assessment of whether masks could decrease disease transmission from mask wearers to others.

Point being that there's not really a conundrum related to things not fitting together so much as a simple lack of good data.
I thought it was just taking a while lol
See my post elsewhere ... I was pointing out there are three things I dislike in native English Speakers (I am one) that I have not yet detected with my Portuguese friends. Now, I can't understand it but I've asked about this and nothing was confirmed or denied:

- Stalling mid-talking with "ummm" or "ahh" while one thinks of more words to say

- Rising intonation to make a statement; usually rising intonation is for questions"

- Over reliance on works such as "like" ... which even now can be used to start a sentence as with: "like, I was going to the store the other day, and ..."

Portuguese is a beautiful language, and like French definitely unlike English, pronunciation of all the syllables is required. In that way it's a more athletic language. In English it's quite important enunciate the first and last syllables, while we compress or cram the middle ones.
Fair point I didn't think that far. But now as I do, per https://en.wikipedia.org/wiki/Idaho%27s_congressional_distri... they are all Republican by wide margin already, so there's no real gerrymandering to do.
The steps of granularity would likely be the Planck length.

His proposal does have some unresolved issues. E.g. distance is quantized but the interactions of those quantized variables produce continuous things that affect other things that are quantized. We don't have enough energy to see the limit yet, but it is possible.
Firefox at least gives you the option of a master password. Chrome from what I recall has consistently refused to have a master password (on Windows at least).

> behavior, upon use of a nonportable or erroneous program construct or of erroneous data, for which this International Standard imposes no requirements

That is literally the definition of UB from the C standard. It is explicitly also about constructs that the standard does not describe. That makes sense: the standard does not and cannot define the behaviour for any construct not in the standard, so cannot impose any requirements for such constructs, and that is all UB is: something where the standard imposes no requirements.
I'm not sure about that honestly. At the extreme there's definitely COVID deniers who followed no precautions, but IME most "normal" people I know felt more comfortable spending time indoors with masks than they would have otherwise. And 6 feet is really not enough spacing in many indoor environments. With things like elevators the other person could be gone and you could still be exposing yourself.

There is also precedence for some of these statistics with Asian countries during the SARS pandemic, and in these places rule following is generally much better.

And with a smaller sample size there are some case studies from restaurant transmission. Staff seem to get infected less frequently than other diners, even though they are in the space for longer. There are a few possible explanations, but the fact that staff don't take their masks off is a pretty compelling one.
