ahem, the DR Congo is basically in a state of civil war. And yeah, basically the air superiority is currently held by the nation state and its allies. A private force can turn this easily. Also, the soviet caches have dried up (while I doubt the demand did) and today in most conflict areas, it should be a lot easier to put a box of cash on the table to get a service than import/export a lot of stuff on your own (you need people and control for that).

It's not that simple. Owning a fighter jet (or even trainer like an Aero L-39) requires both the nod from the ATF, and a bunch of FAA waivers. For a high end jet like an F/A-18 or F-16, It practically requires the Secretary of Defense himself to approve it. Without that approval, Boeing or Lockheed Martin can't provide parts and support for the aircraft.

Notably, Erik Prince of Blackwater/Academi notoriety played fast and loose with weapons import/export/ownership rules, and came very close to being criminally prosecuted for it. Retired Admiral William 'Fox' Fallon resigned in disgust when he realized how far outside the rules Erik Prince was operating.

When Erik Prince suggested letting his private firm handle security in Afghanistan as an outsourced contractor, then SecDef (General) Jim Mattis was dead against it, and blocked it all the way.

As I understand it Bernays was already working in the field long before publishing his book. His early work as a proto PR agent for the singer Caruso, fabricating myths about his prowess, does lend credence to this, as Caruso died in 1921.

It seems fair to say that there were many early adopters of this type of propaganda.
They were studying the human mind, and the esp angle was just a subset. The propaganda techniques are also a subset. Hence it is wrong to say the former was fake and it was just the latter. They were doing it all, and seeing what stuck.(mkultra/artichoke, etc) Maybe I'm misunderstanding your comment, could you elaborate on your meaning?

Literally everyone in this scenario thinks this way at first because they can't comprehend exponential growth. Nobody can, there are actual studies that show nobody can understand it so it's not a slight.

The only way you can convince me based on evidence elsewhere that your scenario is going to be any better than anywhere else is if your leadership in your area is doing aggressive testing, contact tracing and targeted isolation protocols akin to South Korea.
That's the whole point though, those people don't really exist. Basically everyone who does business internationally is, well, doing business internationally. You can either restrict your market to only people who hold your non-dollar currency, hold every currency in the world, or hold dollars. And keep in mind, everyone else holds dollars...

Went over the docs (Google and Apple's), but there are a few things that are not clear to me.

This is my summary of how I interpreted it works:

- A [Tracing Key] is stored locally in every device.

- A [Rolling Key] gets regenerated every day based on the [Tracing Key]

- A [Proximity Identifier] gets regenerated every 15 minutes and broadcasted to other bluetooth devices.

- The Contact Tracing Bluetooth Specification does not require the user’s location; any use of location is completely
optional to the schema.

- Other devices save the [Proximity Identifier] locally.

- History is stored for a couple of weeks

Some questions about how I interpreted the rest:

- The device wakes up once a day and downloads the list of identifiers that have been known/reported to have COVID. It compares on device that you are on that list. Q: Wouldn't this list be insanely long? More so if it doesn't have any concept of location?

- If you have COVID-19, you can report to the servers that you were found to have it. Your rolling identifiers gets uploaded to the "cloud server". Q: Which "cloud server"? Whose cloud server?

Any clarifications are strongly welcomed :)

- If diagnosed with COVID-19, users consent to sharing Diagnosis Keys with the server.

What your comment is missing is that the mortality of ventilators is 66% - 90%. So they're not a good solution for most patients. ICU doctors have been recommending using non-intrusive methods like cannulas as long as possible before intubating. However, that causes aerosolization of corona, so quarantine buildings are needed.

When it comes to actually building a product there is definitely face to face benefits.

However, I'd point out that many software companies have far more sales people than engineers. There has been this expectation that salespeople should fly out, and have meetings, meals, and expensive drinks with the companies they sell to. Now magically that's all vanished, but sales are still happening. The cost of some sales efforts has presumably plummeted.

The procession of a dictator is more nuanced and complex than people realize. A totally typical tactic is to repeatedly fire anyone who will take up the role in a fashion that does not directly benefit said dictator. That anyone was fired from this duty without a clear explanation and justification is cause for alarm. It doesn't matter if there are 20 or 2000 more ready to step into that position. Dictator will keep firing until he sees a loyal drone in the slot.

Maybe this is answered somewhere, but what would you say is the differentiator between Mint and Svelte? Many of the design choices seem similar. I am in the position of starting a new hobby project soon myself and currently Svelte is the one I have landed on.

Or less intrusive measures. We should shelter in place the vulnerable and let everyone else out like Sweden, and this will sort itself out amicably in a few weeks. Leaving the entire population with lasting immunity, preventing any chance of resurgence. [1]

My limited but non-zero experience in real-world situations has shown that "Angry Mobs" are far more likely to be armed than "Peaceful people", across regimes, situations and armament laws, regardless of the initial starting point.

The thing to hope for in "If we run out of food" situation is that some people at least will co-operate. Once it gets to "Angry mobs", and most importantly "who does and doesn't have a gun" - peaceful people will lose, one way or another.

Again, it's a personal & subjective perspective (which is why I've vouched/upvoted your comments - we're all allowed a personal & subjective perspective and it tests our ideas:), but it also means it's less theoretical than for most folks - having been variously in a civil war, starving situation, and facing angry mobs, turns out, last thing I personally wanted to have is a gun - it's just another highly desirable item for an angry mob and paints me as a bigger target.

So I try to have a reserve of food and medicine and important things at all times - but a gun has never joined the list. I know vividly from experience that if it comes to defending my stash, I'll loose very soon - if not to the very first "wave of angry mobs", then very very shortly thereafter. Popular SciFi movies and series notwithstanding :-/
God damn, there is no way this is anything other than just brazenly obvious insider trading. Completely unethical. Our representatives are complete and utter scumbags.

I have no reason to believe you're wrong, I just wanted to point out that we (as a whole community of scientists etc.) can observe an entire range and lifecycle of this approach and that we're aware of the risks based not only on theory but on practice.

Personally I see your proposal as a relatively worthy endeavor to consider.
Personally, I would choose to put the Apple logo first on aesthetic grounds.

Not because I like that logo better but because it is smaller. Since English reads left to right, if the short thing comes after the long thing, it looks lopsided.

Also, since the Google logo is larger, it is going to be more prominent no matter what, so putting the Apple logo first balances that out a bit. Seems fair to me.

No. They could just choose not to sell at a lower price. In a frictionless market someone else would step in and sell the good at the lower price, but in reality if not enough people want it then that third party won’t bother.
That sounds like twice the sound to me due to the additional canceling wave. I don’t trust it to not damage the little delicate bits in my ear just because my brain is able to sum the two waves and perceive silence.
As an aside, I'm not clear why tech startups and VC panicked over this catastrophe. Given their extreme flexibility, I would think this is the most promising sector to do some good stuff at the moment and do well after in any disrupted future environment.
I've been pondering over the idea of offering the option to use physical device, like e.g. a Bluetooth bracelet, for contact tracing in addition to apps.

For contact tracing to have an impact at all, we need a quite large percentage of the population to use one of these apps.
Even if 60% of the population had some kind of app installed and this app worked properly, we would still only detect just 36% of all new infections, since both parties (infected person and person to be infected) need to use the app.
There is a significant portion of the population that does not want to or cannot use such an app, e.g. the elderly, kids too young to have their own smartphone, people with certain disabilities, people that can't carry their phone with them all the time (e.g. while doing sports / working) etc.
This population can still be relevant in spreading the virus - for instance, when loosening lockdowns, young children attending kindergarten / school can bridge the gap between families.

Moreover, even among those that own a smartphone and that want to use the app, I just can't see it all work flawlessly.
Outside of the tech bubble, I see many people with older Android / iOS versions that don't receive updates (which might be crucial for contact tracing to function without having to keep the app open at all times) or people simply failing to install updates.
We also don't want the app to be too sensitive (an infected person that happens to be at the opposite end of the same subway car shouldn't trigger quarantine for you), but also not too insensitive (people might put their phone in handbags or attenuate BLE radio waves with their body).

I think that these problems could be solved by offering something like a standalone Bluetooth bracelet, compatible with whatever App becomes the standard.
It should be possible to mass-produce these relatively cheaply (<5$, which a BLE beacon currently costs).
They would use a Bluetooth chip with know characteristics and are worn at a defined location (wrist), so it's going to be much easier to correctly tune their sensitivity.
The time-to-market will of course be longer than that of a potential app, but it currently seems like we're going to have to live with the virus for a couple of months to come.

The only technical problem I see is that the physical bracelet would need to receive a (trusted) "list of infected IDs" somehow.
Maybe a mesh network of bracelets with smartphones as information providers could work? Maybe bracelets could connect to public WiFi? Or maybe we could leverage some existing low-tech data broadcast infrastructure such as RBDS/RDS (Radio Data System)?
Businesses that require face to face contact (ie. the service sector) employ the most people of any sector in the economy. And then there's manufacturing, resource extraction, construction, etc..., which all can't be done remotely. The amount of jobs which don't require physical presence or face to face contact are a minority of the workforce.
Error occurs when microphone is not plugged in and when I deny microphone permission in browser. Probably a very rare case, but my microphone connection is a bit wonky and sometimes I have to re-plug it to work. It would be awesome if your app showed that I might have a problem on my end.
For some balance:

As someone who is one of those most loyal users and has been using Mozilla since they were releasing milestones of the app suite after the 1998 open-sourcing, then moving on to Phoenix/Firebird/Firefox... I can say I just don't care about this change. I run beta channel, and it was a weird jarring surprise when I first saw it a month or so ago, but within a few hours I just stopped noticing it, and stopped caring.

I just don't get why people end up in arms about such trivial changes to software. Admittedly I used to be like that, to some extent, but at some point I realized this sort of thing doesn't actually affect my life in any meaningful way and so there's no point worrying about it.

Change your mindset. This sort of thing is not worth even the tiniest raise in blood pressure. It's a waste of time and energy to even give it a second thought. Doing so provides no value to anyone, especially yourself.
'If you can't stand the heat, get out of the kitchen'
TLDR (from the last paragraph):

"The lesson here is that having a robust manufacturing industry helps build the potential for the unexpected. It calls for countries to look at manufacturing not only from an economic perspective but as a way of building skills and resilience to survive the unexpected. The unexpected could be war, trade sanctions or even a disease outbreak like it is happening now."

Absolutely.
It’s important to understand where compiler optimization opportunities come from. They’re not magic; they’re determined by the information the compiler has available to it—information about constraints you’ve imposed on it, and information about guarantees it can make.

Using separate variables instead of reusing the same variable will sometimes actually increase the optimizations that compilers can do. Why? Because the version where you overwrite the variable is introducing additional constraints (e.g. keeping X1 and X2 in the very same stack slot called X) that have costs, but whose semantics you aren’t necessarily (or even usually!) relying upon.

For example: you know all that spare register spill space in the x64 calling convention that you’re allocating either way, and which deallocates as a block on function exit? Can’t make efficient use of that if you’re telling the compiler it has to keep both of your pointers successively in the same memory address!

On the other hand, the opposite is also true: sometimes overwriting a variable will free the compiler from a constraint it was under. This mostly comes about as the result of X1 and X2 both holding a shared or overlapping pointer, introducing aliasing (as often happens in the pure-functional data structures OP advocates for.) By overwriting X1 with X2 (or, equivalently, by freeing X1 as soon as you’re done with it!) you can allow the compiler to be more confident that nothing will access the shared pointer through X1.Y any more, only through X2.Y—which may allow e.g. smart pointer classes to elide a synchronization point.

(Note that this assumes a language with a model where a variable directly relates to memory, such that assigning to the same variable implies assigning to the same memory. This is true in most low-level languages, but not in functional languages; in e.g. Elixir, a second assignment to the same variable is actually creating a second variable with a mangled name, and leaving it to the compiler’s lifetime analysis to figure out that the first one is dead after that point.)
RDP is more suited to text as it renders the screen pixel perfect. VNC, on the other hand, converts the screen into a lossy compressed video stream which is why it’s often slow and fuzzy until the image stabilizes. Night and day difference.

Yes that is true, but when the case rate is low this is not a common problem. The ideal size of the grid is adjusted to expected case rate.

If you get ambiguity then you just move those samples across to a new grid (in locations that won’t be ambiguous) and test again.

You would still require a lot of approvals from DoD/ATF etc. to get an A-29 Super Tucano, armed or not. See my earlier comment. https://news.ycombinator.com/item?id=22837486

My understanding is a F/A-18 would probably cost Mr Kirlin $10k/hr to operate. A Super Hornet actually costs about the same in variable costs per flight hour, as they require less maintenance and are younger in age, than a legacy Hornet. Of course, depreciation on a $70m jet is not cheap, which can only be flown for 8k hours, without a major rebuild.

Yes, I think both NYC and Louisiana were seeing death rates above 80% for intubated patients, which is why they are starting to think they need to change the protocol.

In the remdesivir study, death rates on invasive ventilator patients was 13% which is much lower than expected at this point.
If the DP3T app is implemented to spec and creates a new random daily key after the infectious period ends, no.

If the A/G app is not implemented to spec and keeps uploading daily keys even after the infectious period is over, yes.

So, dunno. A/G has a bit more privacy (maybe) for 5x more data volume than DP3T.
None of those facts indicate directly that this wasn't privately driven. They suggest reasons to be skeptical but, at the same time, it's highly unlikely they developed this spec since the DPA was invoked. These companies have been threatened by the Trump White House for years and did nothing to show they succumbed to them. The risk of bad PR hasn't stopped companies from committing sins.

I bet there'll be a few different ways to 'prove' yourself to public places, and people who decide to tell them to 'go fuck off' - well they'll become social pariahs.

After all - the first amendment allows for the freedom of assembly, and the freedom of assembling with whom they wish. Property rights also and all of that.

Is it a matter of losing freedom for safety? Yeah. There's been a lot of 'reasonable' losses of freedom in various things. For example, isn't it a loss of freedom to require a drivers license and insurance (or proof of financial responsibility for California)? Or security at airports? And so on. This may become yet another loss of freedom, maybe temporary maybe not.
This chrome behaviour also drives me mad. At least they allow middle click on new tab button to open a new tab and browse to whatever is in the primary clipboard.

I think I basically never replace the contents of a tab by entering something directly in the address bar. Usually I would just be opening a new tab and my reason to click the url bar is to primary-select its contents or to make a weird edit to the url. But presumably my use case isn’t so common

I don't recall multiple month suspension of broad categories of business in the last 20 years.

That's if we want companies to be prepared for this.
