Source Links for my post earlier today starting with the text "I started studying the US news reports of Covid-19 related to ventilators weeks ago"

Please read through these and let me know of any comments or questions. They strongly imply ventilators don't work on corona patients across multiple reporting countries, so a different policy direction should be investigated for treatment of confirmed cases and lockdown duration. If you agree with what I wrote, please upvote my posts so that people can more eaily find my research.

It appears that ICU doctors, politicians and the public are all working on different narratives, which is counter-productive.

Thank you.

No it actually is to train pilots, but that training is not about 'flying' so much as 'flying while fighting', understanding the engagement envelope of red vs blue weapons, jammers and sensors.

Basically you need to have something tough to go against the JSF or it is a cakewalk and no training is achieved. These Hornets are an excellent 4th gen platform because they have had excellent maintenance and relatively gentle operation. They have all had the HUG 2.2 upgrade and are incredibly capable -- more so than many aircraft operated by the Air National Guard -- but they are too long in the tooth to be going up against modern competitors and be survivable.

JTAC training doesn't need high fast flyers, so just like the article says, using them is pointlessly expensive. Hawks and propeller aircraft are more useful. Fast jet flyers often have type certifcation on them from initial training, perfectly adequate for practicing 9 line briefs.

> And in the end it hardly does anything, as you still get the executable blocked for a month.

This is very much not true - if you have unsigned executables for an app of any scale, 3rd party AV will be extremely Unkind to your app, especially if you try to do updates. Also, how long your app gets blocked depends on how many downloads you get, if your app is popular it can be unblocked in a matter of hours, and once a download URL is deemed trusted, this is largely a non-problem.

Also, while I'll 100% agree that CAs on Windows are a nightmare, the tooling is extremely straightforward, signtool.exe takes your cert file, a password, and an executable, then signs it.
Usually that means your ATA is not configured properly. With the correct dial plan settings, call setup time should be comparable to the PSTN.

I have many other complaints with SIP, mostly related to the assumption by many clients that there is never any packet loss during call setup, but call setup time is not one.

I think that if you really believe your idea has some merit, you should still write a paper. After that you can blog about it for any audience out there and maybe write a follow-up. You're a professional, you know how it works.

In 2004 I started sending a short MondayMotivator to everyone I came in contact with. I asked permission to do so via email. It achieved two things, kept me top of mind with prospects and customers and made sure I started the week well. I didn’t miss a week for over 10 years. Went on hiatus for a bit and then relaunched it when I felt my writing discipline had slipped. You can read them at http://glennfromspike.com/blog/.

The Apple/Google design drops this DP-3T requirement:

2) Enable epidemiologists to analyse the spread of SARS-CoV-2

So anything in that table with epidemiologists is gone.

The remaining caveats are pretty boring:

To do so, the attacker uses strategically placed Bluetooth receivers
and recording devices to receive EphIDs. The app’s Bluetooth broadcasts of non-infected
people and infected people outside the infectious window remain unlinkable.

...

On the other end, a proactive tech-savvy person can abuse any proximity tracing
mechanism to narrow down the group of individuals they have been in contact with to
infected individuals. To do so they must, 1) they keep a detailed log of who they saw when.
2) they register many accounts in the proximity tracing system, and use each account for
proximity tracing during a short time window. When one of these accounts is notified, the
attacker can link the account identifier back to the time-window in which the contact with an
infected individual occurred.

So, yeah, these vulnerabilities still exist and have been pointed out on this thread... but I find it hard to care about these at all.
What are those sophisticated means of communications?
I miss-spoke. I meant to say the rolling proximity identifier could be tracked and fingerprinted.

Furthermore, it's not the same as a phone's location implicating you in a crime. It's a persistent log of your in-person social network that can be reverse engineered every time you get arrested or go through customs at the airport.
I think we're on the same page. Now I don't have the wet lab background (I come from comp sci and did a bioinformatics m.s.). But yea, if I had just a little money to be able to dedicate a consistent amount of time to developing courses I'd do it.

I've tried my hand at doing it completely free a few times, but when it doesn't pay the bills the effort quickly gets put on the backburner.

If you and/or those recent grads start putting something together feel free to reach out and I'd love to contribute. My github username is the same as my HN username and you can get everything else from there.
The majority of that $30,000 is loans that will have to be paid back.

Ask HN: How to answer Enterprise Architecture interview questions?
Hi,

I have had couple of interviews where i did not succeed for an enterprise architecture role. The questions were very normal and such that one can logically answer.

For example, how would you help a client reduce their cloud computing cost? or

how would you sell AWS/GCP/Azure to a client?

For the first question above, i had given a brief point based answer to begin with then expanded on each point.

Not sure how to crack these? Any ideas would be really helpful.

Thanks!
He's a contractor for the USAF. Are you concerned that Boeing has planes?

Who installed the CDC leadership and gutted their budget? It's easy to foist the blame on some faceless TLA govt org without digging just one level deeper to figure out how the gross incompetence was able to manifest.
This is a good thing, and I think in the absence of this solution we would see intrusive solutions backed by governments and mandated by law. I do have two questions:

Is there a plan to verify test results?
Are public health authorities in small countries/regions expected to build and maintain an app and a server from scratch?
Though I personally rebase and rewrite history fairly frequently, so each step is friendlier to reviewers and works independently:

Couldn't you make a new history branch, copy/paste as needed from the original one, and just abandon the old history?

That's effectively what git does under the hood anyway - all your shas are changed, but the old ones are left around. If you haven't named (branch/tag) them, you just don't see them normally, and they may eventually get garbage collected.
IMHO we don't even need to do that, I'd bet 50% of nefarious behavior could be caught by googling for information about companies which Senators buy or sell, and seeing if there's news which would indicate they took advantage of their office (being on a committee approving XYZ, etc).
I'd like to see someone dig up all the most egregious examples of suspected insider trading here and post it in the relevant voter guides for each member's reelection.
There was an attempt to do so, so that professional programmers would be unnecessary. The result was COBOL.

I don't want "close to natural language" because it's too verbose. It's like reading an article in The New Yorker - it takes so long to get anything said that you forget what the point was.

Of course, "too terse" isn't the answer either. There's a sweet spot. I suspect that the sweet spot varies, depending on the person and the kind of code.
I see: SK_(t) = H(SK_(t-1)), where SK_(t) is the secret key for day t.

This seems to align with the statement that knowing the key for one day (i.e. once it is uploaded following diagnosis) allows one to derive all future keys. Is there another section I am missing?

Edit: clarified that daily keys are shared post-diagnosis, to trace prior contact.
No it puts it at November of last year levels.
Even if the two turned out exactly the same in the long run, the slow path has lower volatility than cycles of bubbles and bust.
Similar logic as to why array languages are good can also be applied to why Linear Algebra is a good thing to learn, especially when you're in a calculation-heavy field. A lot of stuff can be abstracted away in a robust way that makes repetition unnecessary whilst also being able to reason about your equations/code.
>There is a lot of crap, but science Twitter is also the only reason I'm on it. Sadly, my own biases against Twitter Kept me off it for 8+ years, but after I started finding the right people to follow, a whole new world opened up, and it is now a vital tool for me to navigate the literature and learn quickly which new tools are best.

That's really interesting, I've been avoiding Twitter for the same reason, but I can see how it'd help keep up with fast-moving niche fields. Maybe I'll give it a try, thanks!

In widely distributed and important spec like this it may be useful to look for what is conspicuously absent or unstated, rather than simply reading the precise positive language.

To my mind this phrase under 'Privacy Considerations' in the Cryptography Specification stands out:

"A server operator implementing this protocol does not learn who users have been in proximity with or users’ location unless it also has the unlikely capability to scan advertisements from users who recently reported Diagnosis Keys."

That phrase explicitly mentions that server operators cannot learn about user proximities.

What I reckon may be unstated there is that it could be possible for adversaries with sidechannel / network monitoring capability to learn those kind of details about users (i.e. internet, cell data, and other data network operators).

If such a side door did exist, it would seem in the public interest to be aware of the scope of the availability of that data, especially given the potential (physical, social) vulnerability and risk of those users.

I'd also like to be proven wrong about the possibility of such sidechannel attacks by anyone who understands the spec in more detail.

Yes, I completely fine with actual hard time pressure, when I know the codebase. When I'm on call and something goes wrong I can fix the code very fast and reliably.

When I presented with a completely new problem I have to think about what is the best tool for the job, how I want to structure my code, how can I test it, what are the edge cases, etc.

Ext JS is the framework in question. The last time I worked on it (Oct 2018), it was about that size shared between two major versions: Classic toolkit and Modern toolkit, including tests and examples. It could be more than that now but I haven't touched it since.

I used to do a lot of things on it, including _very_ deep refactorings with sweeping changes across the codebase. The secret sauce is focus on automated testing: when I left the company, we had ~70,000 test specs for the framework, and the test suite was executed on each commit to every PR pushed to Github. Depending on framework version (there were several in flight), and browser matrix (15+ supported browsers), each test run yielded 500,000-700,000 spec results (and finished in under 20 minutes).

There was a lot of custom tooling around this, of course. Including a test runner that I got open sourced right before leaving the company: https://github.com/sencha/jazzman. Sadly it looks like there were no new commits since I left; I hoped to pick it up later but so far I haven't encountered the need to run significantly sized test suites in massively parallel fashion. Nobody writes that many tests. :)

EDIT: I almost forgot that as a condition for open-sourcing the test runner they made me write a blog post about it: https://www.sencha.com/blog/ext-js-testing-story-under-the-h... :)
You can fix that by coupling their trades with the "index fund", so their bid/ask for X shares at price $Y is combined with some # of shares of the common fund proportional to shares held by all members. Then the trade is executed atomically and we get the same price.
Isn’t ANC effectively twice the sound waves? People treat ANC like hearing protection in office situations and often turn up the volume to drown out nearby conversations. I don’t think it’s “ANC damages hearing” as much as “ANC encourages people to damage their hearing”.
That's not how economies work. They are not zero sum games, they are networks of cash flows which create more flows.
Are you saying, we'll finally see the year of Linux desktop?
This often devolves into extremely fragile systems instead. For instance, let's say you failed to load an image on your web site. Would you rather the web site still work with the image broken or just completely fail? What if that image is a tracking pixel? What if you failed to load some experimental module?

Being able to still do something useful in the face of something not going according to plan is essential to being reliable enough to trust.
Yes. Or just variations in our immune systems. Immune systems are incredibly complex systems. It is difficult to overstate just how complex and varied they are. And they differ between individuals to an amazing extent.

If immunity is important to symptom severity, it may manifest as some weird correlation you might find in a cross-sectional study. Maybe gluten intolerance or a history of acid reflux will be a marker that lets you know what your risk of severe disease are.

Scotland got its devolution referendums and independence referendums without severe political violence, so I suspect that the British would have been willing to let such a vote happen if the Sunningdale agreement had lasted longer.
you won't need the full fleet to fend off any neighboring country – and as I said they offer the whole range now: from small prop-based CAS to state of the art (at least for everyone non-NATO, China or Russia) air superiority.

And I wouldn't really worry about the amount of cash available in such conflicts. In the past it generally was enough for leaders to bribe their way into being accepted citizens of the western hemisphere, see here: https://en.wikipedia.org/wiki/Isabel_dos_Santos
Now suppose, EU drops any support for the angolan government, she wants back her power: probably easy for her to start a civil war. Some neighbors (Namibia, SA) might step up (like they did in Somalia) to help the government if it holds out the initial 1,2,3 ... weeks. Normally they would have uncontested air superiority. Now Ms. dos Santos asks Mr. K.: "How about 4 of your hornets, I heard they kick ass, do you want some diamonds?" (and yeah, they can easily operate from a number of airfields there, I just counted >20 of more than 2km lengths of asphalt: https://en.wikipedia.org/wiki/List_of_airports_in_Angola). And that is how private contracting basically already works for advisors/spec-ops – great to see that extended to state-of-the-art aircraft.

Really great, good progress, all hail the capital!
> What term will you use when something truly bad comes up?

So you are saying it would be OK to call some feature of a piece of software "an abomination" if it were "something truly bad", then?

Well, then why should mikro2nd be prevented from calling this feature "an abomination" if that is an accurate description of how he feels about it?
There's lies, damned lies, and statistics.

Presenting merely data or information is insufficient. The responsibility is to present useful, contextualized information to the public - knowledge.
Let us not forget the hemorrhaging of pilots from the USAF, largely due to the hostile work environment and the general bullshit they have to endure. They simply don't have enough experienced people to provide this function.
And if they're consistently worse than the average, just execute the inverse of their trades and beat the market. :)

Joking aside, I'm surprised that members of Congress have even allowed to trade on the markets, given how much inside information they know.
Thanks. Yes - I will be adding more over time.
There is nothing concrete in what he said. US cities don’t even make the list of top50 most dense cities. Chinese and Japanese cities where coronavirus was contained are on the list:

Beyond that, US cities are usually not dense at all due to people living in single family homes rather than apartments.

Show HN: Building a web app for drinking games over video on shared screens
I would like to restrict only the second amendment. I don't see how a slippery slope argument is remotely relevant. There are dozens of liberal democracies in the world that have robust personal freedom and no right to bear arms. In fact, our right to bear arms is a direct descendent of the British Common Law version that existed for centuries and has been almost completely removed in the 20th century with no loss of free speech or press and no descent into tyranny. The country whose tyranny the founders were worried about.
Darn those millenials, they shouldn't have had a smaller voting-block, shouldn't have spent so much time in low paying hourly positions with no time off, and should have voted before they were 18! /s
Hi HN!

Indie Hacker here. I thought of this idea after trying to play drinking games over video with friends a while ago. It didn’t really work, so I thought I’ll build it. I have some extra time with my country being in total lockdown, so trying to make the best of it.

The games require real-time functionality, so I used Vue.js for front-end with Firebase Firestore as the DB. I’m using Firebase cloud functions to do some BE logic, and Hosting also from FB.

I’m pleased with getting to this point in only 12 days, and the reason for being able to deliver so fast is without a doubt depending on platforms/pre-built stuff/serverless/using emoji’s over graphics.

I bought a Vue dashboard/UI kit pre-built, so styling was minimal. Had the domain lying around for the name.

So, here I am after about 12 days, please check it out! And if it sounds like fun, would love for you to test it with friends! Would love feedback, suggestions etc.

Next steps is to add more games, especially family friendly ones, and build a microsite, currently the whole thing is running in an SPA.

It’s at www.ziago.co

P.S If someone is on PH, and thinks it’s shareable enough - would appreciate a mention.
as I outlined in the other answer, you don't need a lot of weapons to counter non-NATO/China/Russia-air forces. And I'm sure, a person buying state of the art fighter jets can buy some surplus Sidewinder or Maverick missiles as well...
