Maybe vision is helpful with elementary geometry. I don't know how vision would help with differential geometry, geometry of affine spaces, topology, algebraic geometry.

Maybe visualization is more helpful, but you can visualize things without seeing.

A sense of depth and distance, or any kind of metric is helpful, and senses like vision and hearing might be helpful in forming that, but I'm not sure they are required.

From another point of view, math theories are congruent, and you can explain the same things without using geometry, but using algebra, or differential equations or number theory and so on. You certainly can explain any math concept using just modern set theory - maybe it is not the most convenient thing to do.
Thanks for the video and slides, super interesting!

One question: in one of the slides, you mention the Vulkan 1.2 / SPIR-V 1.5 Vulkan Memory model. What exactly is this and why do you think this is meaningful? Would you have any links to learn more? When I read the SPIR-V specification, it mentions that this kind of memory model exists, but it does not put any effort into explaining why it's worthwhile or how it works on a high level.

I love transferwise and use their service for several currencies but it shows how hard it is to get right. E.g. EU customers in the US get a bank account on the name of Transferwise with you as the beneficiary. Even larger invoicing systems in the US can struggle with this as the person is not a US resident, has sole access to the funds and yet the account holder is a US entity.

Customer Service, UX and speed are amazing. But it took me a while to convince US companies to accept this structure.

I feel like solving leetcoe problems would fall somewhere in the category of programs you're describing. (They seem like small problem solving programs.)
The construction of your statement implies that you do not think art, music, and literature matter in the same was as philosophy.
I'm the same. Often incapable of grasping a solution which I know is just within reach. With some problems I can "feel" my brain just blocking, I can't visualise complex data structures. I'll spend days staring at a problem until I give up and ask a colleague who quickly points out the obviously solution. Pretty embarrassing.
I believe that fuzz testing would have found it, yes. I'm not sure if fuzz testing would have been guided towards highly repetitive patterns, given the relative lack of branches in the table construction code, but the incorrectly handled patterns can be very short so fuzz testing should have stumbled upon them (given a pattern that generated an incorrect table, finding a haystack which doesn't work is merely a matter of having the needle occur at a specific offset).

Currently we don't fuzz test MSVC's STL, but that is an extremely interesting area to explore in the future. I played around with this a little while working on std::from_chars() (and found no bugs), but it involved actually porting the code to Linux to be compiled with American Fuzzy Lop, so I didn't permanently add such test coverage to our repo.
Okay, one of us simply doesn't understand what the other is saying.

I'm telling you why normies don't adopt encrypted email (the tooling is fiddly, confusing and hard to use) and you're coming back at me with stuff like "configure dovecot to use virtual folders" which is not something most email users can do.

>Again, you'd probably be better off not trying to with GPG and just using Thunderbird or installing an Android app with encryption. It sounds like you have no interest in configuring anything more complex or working on solutions to these problems without trying to complain about GPG which isn't the problem at all:

A majority of people will not use Thunderbird because more and more people don't use computers any more. Their phones or tablets are their primary computing devices. Thunderbird is not a solution. And there really aren't many good free email apps out there (remember, you're competing with free because a lot of these people are on Gmail already). The biggest alternative mail client for Android in terms of recommendation tends to be K9 mail which on my OnePlus 3 and my Pixel 3 simply did not work at all.

I would guess that the spread of the disease and the rate of infection could be parameters to consider in planning policy for the immediate future. On the other hand, could this result be used to usefully estimate the total values in other regions from the hospitalization numbers?
That was a decade ago. Esp with more traveling (car rentals and many hotels abroad require credit cards), penetration of CC in Germany is very high now. Usage isn't, many like to use their debit card or cash. But even older folks I know all have a credit card they get out a few times a year if no other payment method is available.
Even though an early WHO study showed 95% of cases will show symptoms within 7 days, they still don't know the average age of infection, so it is highly presumptuous to say they are asymptomatic.

I would also assume that the GDPR would impose severe restrictions as to the allowed duration of data collection for contact tracing purposes (in the sense that it shouldn't be legal anymore once Coronavirus ceases to be a major threat), but IANAL, so I could be wrong.
South Korea hasn't done much antibody testing, and they are largely testing people with symptoms. They are doing a lot of it, but they still have a potentially large proportion of infected going under the radar.

Except the fewer people who get (or can afford) the vaccine, the weaker herd immunity becomes, and the more likely a future outbreak might lead to another shutdown of the economy, to say nothing of the profits from a vaccine you might only need to take once per year likely not offsetting the losses from sick workers who can't be vaccinated throughout that year.

The ROI for that scheme seems terrible, but maybe I just don't understand basic economics well enough. It seems obvious to me that they could make more money charging less for the vaccine and more to companies and government for implementation and data infrastructure.
of the links you put on the last page (or other gpu languages you might not have included) what's the most mature way to write decent gpu code right now (even if not necessarily optimal). i'm right this moment working on a project where i'm trying to speed up a blob detection algorithm by porting it to gpu. i'm using pytorch because the primitives fit naturally but if that weren't the case i think i would be kind of at a loss for how to do it (i do not know, as of yet, how to write cuda kernels).

>Bill Gates strikes me as someone who will be a villian to society as he ages.

To a lot of people who were in tech in the '90s, he was also a villain to society when he was younger.
Some organisations are granted special status - for example, CERN is built straddling the frano-swiss border and can issue its own diplomatic vehicle registrations. Not to mention things like the UN building in New York.

If for some reason the US thought ICANN shouldn't be subject to US law, they could do something similar. Being inside a country's borders doesn't always mean being subject to its laws.

Of course, the corruption in the .org selloff doesn't make me feel ICANN needs less oversight. And it's questionable whether the US can grant independence it cannot revoke, at least from an international realist perspective.
Apparently "good cunt" is a New Zealand thing too. I was wonderfully surprised when a Kiwi friend declared me a good cunt.
Probably ended up with the same specificity problem that ruined the German antibody test. It's incredibly hard to test for just a single form of Coronavirus.

Ultrasonic foggers would also increase the amount of salt in the air, so you’d have to run them far out in the sea.

Instead, flood Death Valley with ocean water:

1. Massive evaporative potential.
2. Moisture trapped by tall mountains replenishing the aquifer and making lush surroundings.
3. Massive hydro potential
4. Displaced species not seriously harmed since the moisture gradient would be large (are P. 2)
5. You could harvest the salt prolonging the suitability of the project (anyway measured in centuries if not millennia)

Basically you’d have the lushness of the surroundings of Salt Lake City (compared to the desert anyway). Except there would be a lot more moisture (lower salinity wrt it Salt Lake, moisture better trapped)

You could do the same thing in Egypt at the Qatara depression, except with potentially global benefits. Here the half of the Sahara could be turned into productive farm land.

From experience, (1) isn't really a problem. If payments bounce they do so within a few days due to insufficient funds or fraudulent use. After that, refunds are extremely rare. Esp. since most European countries have easy systems for small claims which allow you to claim the money back.
Schneier makes an excellent point about the usefulness of the contact tracing apps that I (personally) haven't seen much elsewhere.

> As long as 1) every contact does not result in an infection, and 2) a large percentage of people with the disease are asymptomatic and don't realize they have it, I can't see how this sort of app is valuable. If we had cheap, fast, and accurate testing for everyone on demand...maybe. But I still don't think so.

> So I agree [...] that this is primarily an exercise in that false syllogism: Something must be done. This is something. Therefore, we must do it. It's techies proposing tech solutions to what is primarily a social problem.
Just click elsewhere on the page and it goes away without having to make that difficult choice.
I have similar problems. Some of it might be because of underlying issues we'll probably never learn about it, but some of it is also social media and information overload.

There's so much shit bombarding us every day, all engineered to provide a dopamine fix and I 100% believe it's affecting our brains.
If that's truly your fear, you should support real (and acceptable) moves for fighting climate change as a way to head that off at the pass before it comes to be.

Today, if you make a list of all the fascistic bad things that governments have done "under the guise of fighting climate change" I'm pretty sure the set is empty, it's a zero item list. No government anywhere is a green fascist dictatorship, and it seems far-fetched to imagine one. But again, if you think that's a real risk, I urge you to support climate action now so that public support for drastic action doesn't build up.
Every country will do this. Its obvious now that we cant let china use slaves so we can get cheap stuff. Our explotation of poor chinese lead us here. We morally deserve what we got. Pure corporate greed.

To see such a dangerous, totalitarian ideology expressed so casually is terrifying.
> similar to how Bitcoin salespeople spent most of a decade saying it’d be better than cash and credit cards before trying to claim they’d had different goals all along.

As someone following Bitcoin for a long time since just after genesis, I can assure you that replacing cash and credit cards was never on the original agenda but instead a byproduct of the goal. Make no mistake, the goal was always to decentralize currency and give the “power” of money back to the people. That said, in a decentralized system, there can be more than one goal and goals do not need to be unified across participants. That freedom is one of the beauties of decentralization.

As long as a third party central authority controls our money system, we will always be subject to the whims of the few. Bitcoin is helping to liberate us and it’s absolutely working.

> it’d be important to have real cost and control information to show that it wasn’t trading ICANN for a different group which has similar control

This exists by virtue of our trust in cryptography - which for me is absolute.

> As an aside, Symantec screwing up does not seem relevant to a discussion about ICANN. Perhaps you could explain why you believe it to be?

Less directly and more by way of overall system architecture, the separation of DNS and “truth” has caused many issues to the Internet. It’s relevant because Handshake finally combines DNS and truth [1] by essentially completing the once incomplete DNSSEC.

> If it is “only” two times more, then we need to have an adult conversation on how many lives are worth saving vs our society going through something akin to the great depression.

Why is it that only two choices ever exist when this argument is presented? Choose either death by virus or death by status quo economy. It seems like a more pleasant alternative would be reshaping our economic systems to be more resilient against such a crisis which will almost certainly occur again in the future. Maybe the current ownership and distribution models and how they relate to globalism aren't compatible with something that is now simply a fact of life.
In pretty much every country you need a director or similar who's a resident of that country. There are agencies doing that for you but that's not cheap and not without risk. Running a company without residence is usually not worth it for small companies.

The other issue is that RAID (even RAID 6 with no dead disks) fundamentally cannot deal with data corruption or any of other fun bugs hardware likes to throw at you like phantom reads and writes. This is because it has no checksumming and most implementations will overwrite the parity if a mismatch is found. There's also the RAID "write hole" problem, but most implementations have worked around that since the mid-2000s.

I switched to ZFS a few years ago and it's really quite amazing. In fairness, raidz does suffer from the same "resilvering takes a long time and increases the chance of subsequent failures" problem, which is one of the reasons why mirrors are more commonly used. Though unlike RAID, ZFS knows which data on the disk is actually used so can reduce resilver times pretty drastically.
Can this study really be expected to provide data on the viral load of the point of infection, and at the time of infection? (I would guess that measurements of the distribution of the viral load, after the infection has progressed for some time, would be dependent on how the person's imune system is responding, and conseqently not good evidence for this proposition.)

If not, then is this a well-established feature of respiratory virus infections?

In other words, to what extent is this claim backed by evidence? And is it evidence from studying C19 specifically?
Yes. Same url just drop the "_en": https://www.land.nrw/sites/default/files/asset/document/zwis...
Everything you say is true and yet - it also makes the amount look lower than it is (about .15%), which is still pretty small but it's O(100) vs O(100k) rather than O(10) vs O(100k).
NZ is mostly just testing people with symptoms too. That's pretty worrying to me given data like this article's. I think we should also be testing big random samples from the population. We've started testing hundreds of apparently-healthy volunteers, which is a good start: https://www.stuff.co.nz/national/health/coronavirus/12107495...
15% positive is not representative of the total German population. This is a sample from a small town with a known cluster outbreak from a festival in mid Feb, where a significant amount of people are believed to have gotten infected.

>With all the projects I've worked on, I've always found unit tests to be the best possible place to catch bugs and errors

Have you considered that that might be due to the nature of the projects you've worked upon rather than the nature of unit tests themselves?

>it's often beneficial to create a unit test that helps catch the same error before it you get to the integration test area, not always, but definitely if you have something that fails more than once in an area.

It depends upon what the bug was. Sometimes it's possible. Sometimes "replicating" it with a unit test is expensive and largely pointless since the unit test won't catch that class of bug in the future and will break as soon as you change the code (e.g. I've seen people try to create unit tests that mimic race conditions before and the results were horrendous to read, pointless, and didn't even catch race conditions).

>That being said, tests are designed around the code that is being tested. As technical debt and refactoring of existing code happens, you do often need to rework tests. Many people allow tests to go unrefactored, and they become their own set of technical debt

The higher level and the more behavioral the tests are, the less they have to be changed when the code is refactored and the more confidence that they give you that the code actually works afterwards.

The absolute worst situation to be in is with a bunch of unit tests that are tightly coupled to code that needs refactoring. Those unit tests' breakages signal nothing except that you've changed some code and they demand expensive repairs before breaking again in the future - again, because an API endpoint was refactored, not because a bug was introduced.
I suspect they don’t talk about it or consider appeals at all, because they feel they have no need to bother with any sort of customer service. They are king of the hill, and always have millions of more users eager to sign up. There seems to be little reason for them to bother resolving any issues. Much easier for them to just ban the user and ignore them.
