There's quite a difference between either forcing Apple and Google to build such a feature, which seems hard, vs. just forcing them to turn an existing feature on.

Same for turning such a feature on surreptitiously vs. installing such a feature surreptitiously.
> The “prank” danger: someone just pressing “I’m infected” for fun.

How about you can only check the "I'm infected" box if your phone is near the phone of a health worker?

Another idea is that you get a code in the mail from the hospital which you have to enter in the app.
Perhaps more implementable: IM2000.

https://en.wikipedia.org/wiki/Internet_Mail_2000

TL;DR: Each sender has or subscribes to a reliable mail server. The mail server does not deliver mail to recipients; it sends a tiny notification (restricted set of headers + UUID) to each recipient's reliable mail server. The recipient requests (or doesn't) the whole piece of mail via HTTPS or similar. The basic anti-spam tactic is to reject a whole server because it has sent you spam in the past.
For a somewhat similar but more modern configuration, there’s Burt Rutan’s Boomerang: https://en.wikipedia.org/wiki/Rutan_Boomerang
> The police could quickly see who has been close to a murder victim: simply report the victims phone as being ‘infected’.

> A company could install Bluetooth beacons equipped with this software at locations of interest (e.g. shopping malls). By reporting a particular beacon as ‘infected’ all phones (that have been lured into installing a loyalty app or that somehow have the SDK of the company embedded in some of the apps they use) will report that they were in the area.

I see these as possible exploits indeed. But the points are a bit confusing. I would love for the police to be able to stop a serial killer from killing more people. But they will do by exploiting a COVID-19 contact tracing app? And we will be mad at them?

Or, as an easier solution, a dedicated email forwarding service. I've been using one for about 15 years now and changed the actual email service provider a couple of times just by updating the forwarding address.

Of course then the problem is to identify a reliable email forwarding service that won't go anywhere.

Kotlin is actually at a disadvantage when it comes to design. It has little to no influence on the Java platform it targets and its ecosystem (or on the Javascript platform and ecosystem it also targets), and so it is forced to shape its designs to fit its environment, while the Java language can shape the ecosystem and platform with its design. You see this pattern in records vs. data classes, coroutines vs. Loom, and inline types in both languages. Kotlin's solutions are always more complex and less harmonious in their environment; they need more knobs and joints so that they could fit the contours of the existing constructs around it, on which they have no power. Don't get me wrong, it's doing fine with the cards it's got, but it's clear that it does not have the freedoms of a "platform language."
In my experience people call those sorts of things broken or not working, rather than (soft or hard) bricked. So people would say things like "the power went out in my house and soft bricked my TV until the power company turned it back on"? It's interesting how language evolves.
It's partly the threading structure. If you ignore s subtree that seems uninteresting I think that helps what you're talking about.
Generally I agree that location tracking is already relatively widely done, and the Apple/ Google protocol makes reasonable efforts to preserve privacy.

I do share some caution, however -- tracing 'personal contacts' by BTLE is likely much more personally specific, and hence significantly more intrusive, than just location.

If such mechanisms became more generally available they would likely become used as part of the machinery of repression in states such as China. Or everywhere (depending on our future).

Location is fairly imprecise as to social contact, but I guess the concern would be that this will be accurate enough to track dissenters, find their contacts, and accuse/ imprison you.

Trying to install Logitech MX Master 2S on Ubuntu 16 and it detects the device on bluetooth but not as a mouse device. So it doesn't move, it's dead. Windows and Mac work just fine. Apparently Logitech can't be bothered to have drivers for Linux or Linux doesn't know Bluetooth well enough to handle all mice.

The Daddy of Big Numbers (Rayo's Number)
> Published keys are 16 bytes, one for each day. If moderate numbers of smartphone users are infected in any given week, that's 100s of MBs for all phones to DL.

> That seems untenable.*

> It's a lot, but untenable? If 300 million report as infected, that's 4.8 GB, coincidently the size of a DVD. So 2 hours of Netflix, 1 hour at 4k. Very easy to cache this data close to the edge, too.

Just doing the math here, assuming a perfectly efficient wire protocol was used, each infected person would amount to (16 x 14 = 224 bytes) of data to be transmitted.

Assuming we see 150k new cases per day, worldwide (worldometers is reporting 100k new cases per day as the peak, and let's factor in 50% margin), this would be 33.6 MB of data per day.

Since you only need to transmit that day's data rather than the full database, a very basic sync protocol could be used here - the phone simply stores the sequence number of the last identifier handled, and it can be given subsequent data. This could even be done with a static (and thus cacheable) server if cases are chunked sequentially into 1MB chunks, and addressed by filename based on the last case ID.

For clarity here, case ID would be simply be the sequential number that a given tracing ID has in the server-side record, so you only need to fetch data you haven't already checked against.

That's a useful perspective to be aware of, and if this were a pure susbtitution of one mechanism for another then that could be a clearer win.

I think it's also true that deploying yet another potentially privacy-invading technology makes it more difficult for privacy advocates and lawmakers to deal with and reduce existing overreaches.

Actually, I think humans tend to live very close to bats.

We may not interact directly with them but our buildings are very good nesting sites for them. It's common to see bats in barns, stables, or attics.

Sometimes people do also eat bats. I think this especially important regarding Ebola as fruit bats are indeed sold for meat in West Africa.

In the wild bats can get in contact with other animals that are in turn eaten by us. It seems to be a possible route for SARS through civets.
Sounds fabulous ... how do you do that? You say:

How do you do that when you have:

So, how do you install Arch Linux?
I was just using the PAH as an example, but the issue in the lungs results from vasodilation (please correct me anyone if I am wrong). So vasocontriction might slow the leaking of fluid into the intercistal space.

Regarding the zinc deficiency; we see a large variation in outcomes after infection. Part could be viral load, but since we know people with "comorbidities" are more vulnerable to bad outcomes this delta should be an area of interest. Some people are totally asymptomatic!

The comorbidities (let's say heart disease) are caused by environmental or genetic variables. It seems zinc deficiency, to me, might be a common thread to both comorbidity and infection outcomes.

Since ACE2, a zinc metalloprotein which uses zinc as a cofactor, is in the alveoli and is the receptor for the virus, it would make sense to look at this as a serious possibility. ACE2 is a "Therapeutic Target for Heart Failure"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3944399/

And zinc plays a role in the lung disease as well:

https://link.springer.com/article/10.1007/BF00944606

Interleukin-1α (IL-1α) production by alveolar macrophages in patients with acute lung diseases: the influence of zinc supplementation

"These results suggest that zinc can regulate the production of IL-1α from AM in patients with pulmonary tuberculosis or bacterial pneumonia."

Both anecdotally and experimentally there is evidence that zinc inhibits the replication of several virii. So zinc deficiency might make infection more likely and weaken the immune system to make outcome worse.
> You will need at least 1k-1.5k EUR net per month, which means earning 2k or more gross.

On top of that we have BAföG which, if your parents don't earn very much, can be enough to study or at least be a good support. While BAföG is still some kind of loan, you only have to pay back half of it and the rest has no interest.

From what I found [1] about 41% of children are eligible for studying at a university. While I don't think this is ideal and the unfortunately the early tracking still does it's part to keep people from less privileged backgrounds out of uni, I do think that a system where access to higher education is tied to formal graduation sounds fairer than a system where you have to be well off or very gifted to make it to uni.

You’re missing the main point: if the government can do this, it will, independent of this contact tracing platform.

Also, there is no location data in this platform, and Google and Apple don’t have the data that does exist.

Because it's no better an idea than it was 25 years ago when Spam first became a thing and there was another genius throwing this idea around every other day.

First, there are some important use cases it would destroy (especially mailing lists).

Second, it's impossible to implement gradually. Protocols and infrastructure would have to change drastically, everywhere at once. Not feasible.

> People that were not placed into Gymnasium at age 8 are set on a course where, once they turn 18, do not get to go free Uni; they simply are not allowed to go to Uni at all!

This is curious. Can you elaborate?

So if you don't do a gymnasium class (i.e. physical education I guess?) at 8, you are barred from going to uni at all, regardless of grades? So you might suck at the parallel bars or pommel horse as an 8 year old, but be an absolute mathematical genius but because you couldn't do 100 star jumps in 60 seconds you can't go to uni? Who decides if you can do the gym class? What is it based on?

This sounds very bizarre!

I only have UK experience (or at least how it was years ago - I might be out of touch): unis set subjects+grades they are prepared to accept and if you are predicted to get the grades (or already have got the grades) then you are eligible to apply regardless of what you did as a child. In the UK you do pay these days though - when I went it was about £1000 a year but it is more than that now (9k I think)
Exactly right. And as civil libertarian as I am, I'd rather have Google and Apple tracking my location for this prosocial cause than serving targeted ads. And it's not like Apple and Google aren't already tracking iOS and Android users anyway (albeit user-tweakable).

It's another case of focusing on the short term to save money. In the long term it damages their reputation and some frustrated businesses/users might start to consider moving away from their products if a viable alternative exists.

Unfortunately, many of us tend to run into the 99% of professional Java devs still stuck in the old, almost meme-level culture of pre-Java 8, where:

* var is a sin (if the Java version is even high enough to utilize it)

* Methods frequently have 3 arguments by default
* Getters and setters are nigh-on useless and verbose, existing primarily because one doesn't trust the coder next to him

* Names are atrociously long and laid out in a way auto-complete helps zilch (25+-char names are not uncommon even for local variables)

* Methodology is still primarily stuck in its old GoF OOP AbstractCreatorFactoryFactory ways

Java is doing good and making leaps to improve. I can't say the same for the culture, which is mostly due to it attracting tons of people who have no innate skill or desire to learn programming, mostly there to occupy a job that pays decently well and make zero effort to improve. Or worse, it used to attract those kinds of people, who now occupy senior/principal/lead positions and enforce the old way of programming under the guise of "consistency" (Consistency is important, but using it as an excuse to not adapt is simple abuse). That attitude is a lot less prevalent in Haskell communities, where the environment itself preselects for programmers with an innate interest.
For a while I thought it was about bureaucracy, but it's just someone annoyed by seeing non-whites at American universities. Nothing to see here.

Seems like a false dichotomy.
I like “persona”.
As someone who has planned on returning to grad school this fall to finish my PhD in computer science in hopes of becoming a professor at a teaching-oriented university, I am worried about the future of the occupation of being a university professor, particularly from the standpoint of being able to do research. One of the things I wonder about the post-COVID-19 world is what's going to happen to research as a career, whether it's in academia or in industry. In computer science I've noticed these two trends occurring in the past 30 years:

1. Industry has largely moved away from funding long-term blue-sky research, increasingly shifting toward short-term, product-driven research projects. We have moved from places like Bell Labs and Xerox PARC where researchers had a large degree of freedom to places like Google today where researchers are assigned to product teams (see the paper "Google's Hybrid Approach to Research" which describes how research at Google is operated: https://research.google/pubs/pub38149/).

2. Academia has its own challenges: (1) the competition for a professorship due to the fact there are more PhD graduates than there are professorships, (2) the competitive environment for obtaining research grants from the NSF, and (3) the increased reliance on adjunct faculty members, who don't have tenure.

The economic effects of this COVID-19 pandemic will undoubtedly lead to universities reducing their hiring. Some universities may even face closure. The sudden shift to online teaching may also have permanent effects on the future of university education.

I believe that there are many opportunities for students that will become available if online education becomes the new normal, especially if online education leads to reducing the cost of a university education, which is a serious problem in the United States given the student loan crisis.

However, I'm concerned that a move toward online education will accelerate the trend of adjunctization occurring across academia and may even lead to the concept of tenure disappearing at all but the most competitive schools. I believe places like Stanford, MIT, and Harvard will emerge from the post-COVID-19 world just fine. I also believe that public research universities like UC Berkeley and University of Washington will emerge fine. But what about regional comprehensive universities such as the California State University system? What about small private universities that don't have the prestige of places like Caltech or Harvey Mudd? It's these types of universities that will face the most pressures to adapt to a world of compelling online educational choices.

I'd like to still be able to pursue a career in research, ideally with autonomy and the ability to pursue long-term projects, but between the trends that have been occurring for the past 30 years as well as the challenges of a post-COVID-19 world, I might not be able to pursue such a career.

> The other difference of course is that in Germany, only a fairly small proportion of high school students is even allowed to go to Uni.

Among 25- to 29-year-olds in United States, the percentage with a bachelor’s or higher degree is 37 percent, and the percentage with a master’s or higher degree is 9 percent.

For Germany, the best guess I found was 32% in tertiary education. Which is lower, but not that much lower. It is not like most people in the United States would have college degree.

> When polled, 87% of students answered that they were dependent on financial support from their parents and 12% received state-sponsored loans [1].

The amount it costs to pay for "accommodation, food and participating in general student life" in Germany is significantly less then to pay for "college itself, books, accommodation, food and participating in general student life in United States. The fact that majority of middle class student can do it on parental help alone makes situation massively different then when students have to take on debt.
