> Well, a study of a German town showed 15% are already immune/have had it and a mortality rate of 0.37% vs the flu at 0.1%

You are comparing apples to oranges and calling it grapes.

It is 0.37% infection fatality rate (including clinically non-significant cases) vs flu 0.1% case fatality rate (from clinically significant cases). case fatality rate for covid-19 is much higher (say 2 % in Germany). Note that these are fatality rates, not mortality rates.

Second factor is that population has no imunity to SARS-CoV-2, while has some immunity to flu strains. Which means much more infected and therefore higher mortality rate even with the same fatality rates.

Overall, it seems to me that without any precautions it would be 10x-25x higher overal mortality (say 0.2 %) than seasonal influenza (say 0.01-0.02 %). Not great, not terrible.
Probably, but at that point you'd stand out to humans! Imagine being at an airport...

> $1200 is barely enough for one month for most people.

It's only enough if you stop paying your mortgage/rent and utilities. It's certainly not enough for most people if they still have those expenses on top of everything else.

Though, admittedly, lots of people are getting substantially more than that -- a married couple earning even into six figures gets $2,400 plus $500 per kid.
So first off, doubling the amplitude is a 6dB increase in SPL. So not that bad actually.

Second off, instantaneous sound is only a health issue when it's really loud, like a gunshot (130-140dB SPL) near the point at which the ear drum ruptures. That means that you need to be in an environment where the background noise is dangerously loud to begin with, and because of the way sound is made - this might be unlikely. Which is interesting, because early ANC did have these problems - when it was being used initially for military applications (helicopter/tank pilots iirc).

Lastly the important thing to remember is that ANC is usually part of a dual pronged approach to ear protection. Latency is a problem when you need to cancel high frequencies (where you get past about a quarter wavelength and interference can become constructive), but ANC excels at low frequencies (below about 500-1kHz it can be remarkable even). This is great because passive reduction strategies (sealing off the ear, thick padding, good fit/headband adjustment) are much more effective at high frequencies.

So TL;DR it was a problem, been fixed, and where it might happen is pretty rare for a consumer.

Also noise rarely spontaneously inverts phase at a particular frequency. That'd be weird.

I was thinking, if the error exists between keyboard and chair, I want the strictest failure mode to both catch it and force me to do things right the first time.

But once the thing is up and running, I want it to be as resilient as possible. Resource corrupted? Try again. Still can't load it? At this point, in "release mode" we want a graceful fallback -- also to prevent eventual bit rot. But during development it should be a red flag of the highest order.

That write-up was based on extremely early CFR data, with no population studies having been conducted at the time. Latest data is pointing to, as I called out, a fatality rate of 1/10th the CFR. This is especially true as we're counting anyone who tested positive for COVID as a COVID death, even if they were hit by a truck.
"Inflationary spiral" is the explicit policy. The assertions seem to be that stocks must always go up, and housing must always go up. That's inflation. Manufactured goods don't go up as much because they continually cost less to make and distribute, usually through offshoring and consolidation, hollowing out local economies.

The reason is that people are far too quick to leap to this interpretation, and since we have next to no data about each other from HN posts, pretty much every divisive topic gets drowned in such insinuations if allowed to.

Being a manager and hirer is very different from being the interviewee. It's great to believe that you could have some innate ability to judge one's empathy and character in a set of interviews but so much of that runs to favor people who can talk well, which is a wholly different skill from being to code well. Saying technical interviews are disguised IQ tests is quite the horse-shit metaphor. I won't dig into all the problems with IQ tests. Certainly some people have innate ability to do well in quantitative tests, but I know so many people who have put in so much work to get so good at what they do against difficulty and belittling their success at interviewing as something inherent like IQ is awful. Getting to that level takes experience. It takes grit. Programming is a highly technical skill, I have worked with people I don't get along with and people I can't talk to comfortably who have written amazing code and when I am reviewing code that is going to be depended upon by millions of people each day I will always merge good code over someone I like personally. Lots of developers also have responsibilities that use empathy and character and leadership and those people you should always hire along that rubric as well, but if what you need is strong technical skill and ability to solve hard problems with code. You have to find someone who can program well; after that you can have a lot of flexibility in how you work with them and what other responsibilities you give them. I think you are off in comparing programmers to white collar professions. Compare them to skilled professions ala crane operators, machinists, or surgeons. If you don't have hard technical problems then you have the luxury of not needing people who are very good technically, so you can have the luxury of rounding out your interview, but if you have programs for which code quality is very important, you should trust someone who can build good software.
Thanks for the thoughts @danieltillett. I'm sorry you are not getting more traction on the idea. I'd sign up for this if I had this!

IANAL but I did run an infection detection medical diagnostics startup for 3yrs that I co-founded. Since we're on HN, perhaps here is how you might get traction (note, i'm just throwing this out move-fast-and-break-things-style for the sake of brainstorming):

1. Form a company, announce the idea bigtime! (Incorporate overseas for liability protection?)

2. Sell a sequencing service that tells you the strain you have -- offer no medical advice. Not a diagnostic for medical purposes, more like 23&me (does this get around regs?)

3. Offer a free matching service to find locals with the strain, perhaps with an app to validate their strain, etc. (some incentive for the customer?)

Note this isn't legal advice, but it would be awesome if someone with the correct background could provide feedback on this approach.

As for my startup, we sold overseas in easier reg jurisdictions -- we were never able to break into the US market.
I meant culturally in the USN. TOPGUN used to be all air to air, all day. Now it's strike fighter training, E2 training, as well as the classical A2A.

This may be better in some ways since the entire goal of TOPGUN was to train the trainers who would go back to their squadrons and improve capabilities. And that role has changed dramatically since the 80's where being the best pilot meant you might leave the Gulf of Sidra alive. A2A combat hasn't been important for over 20 years. We'll need to reinvent it for the future I fear.

Well, a materialized view is denormalized data. You distinguish it from the “underlying data model”, but you can do that in nosql as well. Also, materialized views still tend to be oriented to rectangular data, which isn’t always how you want to access data.

I agree with the general point that Postgres and other relational databases can do nosql things (and nosql databases can do relational things).
No, you really couldn’t. You could come up with all sorts of reasons for disliking them, or wanting to harm them, but that’s not the same as a reason for expending the huge economic, military and human cost of invading them. To invade a country you have to be willing to pay the price of doing it. Nobody has a good reason to want to pay the price of invading Pakistan. Not even India.

That could change, sure, but that’s not the situation as it stands, and if you can’t see how that works, I’m not sure how I can help you get there.

No. Where have you been? People complain about facebook, instagram, linkedin, etc all the time and encourage others to stop using it all the time.

What is mindblowing is the amount of worship for Apple here and the amount of support this has. And preventing "thousands of people from dying" is no excuse for this because we know this has nothing to do with preventing deaths.

The amount of love that Apple, Microsoft, etc has on every apple/microsoft thread is a tad bit suspect in my opinion.

Why would the specs or details matter? It's a matter of principle.

"People might die" so we need to spy/monitor/track you is a very north korean mindset. But then again, they also use an existential fear ( US invasion ) to enforce complaince amongst their population.
That's even better. IR won't cause skin cancer.

This had some neat benefits: in the 90s I worked for a COBOL vendor (Acucorp) who had a bytecoded portable runtime which allowed you to run a binary on systems ranging from 16-bit DOS to Windows NT, most Unix variants, VMS, etc. (our QA matrix had ~600 platforms & versions). The display section meant it could adjust to the platform: on DOS and other consoles, you had text controls but on X11, Win16/32, OS/2, and Mac it had native GUI widgets, with native validation UI. It wasn’t beautiful out of the box but it was familiar, consistent, and accessible.

The same was true of the standard indexed storage: a different runtime could use a SQL database for storage without recompiling the program, which was key to some gradual migrations to Java. A similar feature allowed remapping invoke calls to run on a remote server.

At one point we produced a NPAPI plugin version: install it in Netscape and your client ran the UI while the data access and RPC calls happened on a server. All I can say is that it seemed like a good idea at the time.

Yup. It also had random chat feature which i enjoyed quite a lot. Made my first online friends (whom i ended up meeting in real life, and are still friends with to date).
At one of my previous jobs, I was responsible for designing and building a webapp to replace a high speed data entry system that had been written in cobol that was used to input large legal documents (several thousand lines of data in some cases). We had two objectives, data entry had to be as fast or faster than the old system and the training time on the new system had to be faster.

We blew both objectives out of the water. Training time went from 3-6 months to about 2 weeks. We had a variety of modern UI concepts like modals, drop downs and well behaved tables that dramatically simplified the work flow. We also had a full suite of user defined hotkeys, as well as a smart templating system that allowed users to redefine the screen layout on a per use case basis (the screen would be reconfigured based on what customer the user was entering data for example).

For performance, cobol typically requires a server round trip every time the screen changes. We simply cached the data client side and could paginate so quickly that it actually caused a usage problem because users were not mentally registering the page change. The initial screen load took slightly longer compared to the cobol system, but the cobol system required 40 screens for its workflow whereas our system could do everything on a single screen.

I guess my point is that modern systems are capable of much better performance and user ergonomics than cobol systems. We have a lot more flexibility in how UI's are presented that let us design really intuitive workflows. The flexibility also lets us tune our data flow patterns to maximize performance. But most modern development processes do not have this kind of maniacal focus. Systems don't perform because most product owners don't really care that much at the end of the day. Once you care enough, anything's possible.

COBOL was the first language to take data format seriously, with "records" and a "data division". To some extent, it still is. Look at the gyrations people go through to get Java or Python to talk to an SQL database. The programming language itself has no clue about database layout.
