Titanium dioxide is a photocatalyst:

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

That article mentions that when it is coated with other things it does not penetrate the skin. However "self cleaning" paints that cause the disintegration of organic matter that lands on the paint also use titanium dioxide:

https://www.sciencedirect.com/science/article/abs/pii/S09596...

So what does this self-cleaning ability do to the skin? Remove the outer layer? Kill the skin microbiome? Maybe the same encapsulation prevents this happening? It is hard to believe some particles would not escape encapsulation. I don't know of any other catalysts in general considered safe to eat.

Actually they use a RNG that in the case of slots, has a kind of virtual reel with multiple assignment.

If you like, add a bit of skill that gives the primates the feeling of control (video poker) or when you let loose of the handle or press a button (which simply grabs a number).

Stir in a bit of marketing pizzazz (off-by-one on slots, enormous number of simultaneous smaller bets, low payoff better odds vs. high payoff worse odds) and you can get the mark to stand there for a bit longer.

Networking, recognition and databases on players, etc. add more wrinkles.

In any case, I don't doubt that a Monty Hall bet could be wrappered into the game somehow to give the appearance of better odds than really exist.

(hopefully I got this somewhat right, I've never designed any gaming stuff. I'll bet that a gig at Bally or IGT would be a real eye-opener.)

Having recognised (from crystallized experience) the nature of the problem from the very first hint, I went straight for the jugular at the first opportunity; any residual uncertainty about the diagnosis was extinguished by the wording of the answer prompt, which to my mild disappointment took all the drama out of the reveal.

Yes it does. Or more precisely, it matters whether the host could be counted on to do so reliably; the mechanism for that doesn't matter.

There's a difference here, that our language obscures, between procedure and hypothetical.
Not at all. Once the door is opened, it doesn't matter if the host knew there was a goat behind it or not.

Edit: The host's knowledge only matter if the host can choose not to open a door.

Apple is one of two companies, that can single-handedly shut down any business, globally, that requires mobile software to function, at any time for no reason. When our national governments required contact tracing software to deal with the pandemic, it was Apple and Google that could block democratic government from protecting it's people.

This has massive implications for liberty, economy and national security. The private party metaphor is simply delusional.

Free space is commonly used to refer to EM propagation in air in RF contexts. For example: https://en.wikipedia.org/wiki/Free-space_path_loss Here the distinction is between propagation models that include ground plain, terrain, or airborne clutter.
An intuitive way to think about the problem is from the perspective of the host.

Sometimes the host has 2 goats he can pick from to show, and sometimes he only has 1 goat he can show.

66% of the time the contestant chose a goat, so the host has to reveal the only other goat 66% of the time. So switch.

I would agree that there has been a lot of problematic race rhetoric posed by certain BLM aligned folks.. and would definitely posit that such soft censorship is a problem for the development of a mutually beneficial understanding of the racial problems plaguing this country between members of different races (there might be a more elegant way to state this).

An example of this aggressive, non-empathetic, censoring attitude that grinds my gears would be when that FB employee tried to publicly shame a colleague for opting not to put a BLM banner on the developer docs of RecoilJS. The whole mantra of "Silence is violence" can apparently now be used to accuse anyone of the terrible thoughtcrime of not talking about racism at all times.. even in places and situations where it doesn't make sense or wouldn't help the cause.

Extrapolate this out to how many people are unwilling to consider or merely listen to viewpoints that aren't in complete alignment (with whatever the accuser holds to be the absolute truth of non-racism).. yuck.

Interesting, although I suggest it much more likely that this cat also really is triggering some kind of "snake recognition circuit", it seems to be driven by some desire to make sure each cucumber is "dead". If it were only about liking cucumbers you would expect it to gobble down the nearest delicious thing it sees, which in my own observation of the felis catus, this is their default behavior when there is favored food and no danger present, they tend to act like greedy vultures, though it differs from cat to cat.
I don’t think you need the 100 or 1,000,000 doors thing.

If you decide before not to switch then your goal is to pick the car which you have a 1/3 chance to do.

If you decide before to switch then your goal is to pick a goat which you have a 2/3 chance to do.
> vs "the treadmill moves backwards to keep plane airspeed at 0".

You might be correct in thinking people misunderstand it as that, but that's physically impossible, so I don't think you can argue that people have some sort of alternate understanding under which they are actually correct. That's just one type of wrong reasoning people might apply to the problem.

Add to that, in your hypothetical understanding of Monty Hall, that actually still doesn't change anything. Because even if the host picks a door completely at random, you still should always switch, it would just sometimes be the case that the host goes "ohh, that's to bad, I revealed the car and you can't win it now", but obviously that doesn't do anything to change your odds, because you're always better off or the same by switching, it's just in the unfortunate cases you'r switching from 0% change to 0% chance. But that doesn't do anything to change the fact that if he didn't reveal the car you're still going from 33% to 66%.

I don't understand how this could be. If you start over when the host picks the car, then isn't that the same as the host picking the goat every time, i.e. the same as the host knowing.
24 hours a day, man. I'm always byte swapping.

(I'm not sure how to answer the question... what do you mean, "when?")
Why do you think that is? I'm not too familiar with local politics. Generally, I believe studies have shown that banning cars from main street in small/medium cities generally increases business, but I've heard of a phenomenon where all the non-main-street businesses make an uproar about how "unfair" it is that main street will be getting more business, and so the whole idea is scrapped.
Imagine there were 1000 doors, one of which had a prize, and you picked #123. The host then opened all the other ones except #456, and they all had goats. Should you switch?

>"BLVDS (Bus LVDS) - National Semiconductor
Desiring to extend the benefits of LVDS, National invented Bus LVDS (a.k.a. BLVDS). This was targeted at
heavily loaded backplanes where card loading and spacing lowers the impedance of the transmission line as
much as 50%. This loading effect, and the need to terminate the bus at both ends for multipoint applications,
required a change to the driver's output. National boosted the output three fold to the 10-12 mA range. A
100-Ohm transmission line, loaded down to 54 Ohms by the cards, would then need to be terminated at both ends
in 54 Ohms. Thus a driver would see the two terminations in parallel and need to drive a load of 27 ohms
minimum (higher is acceptable also). Thus for LVDS signaling levels, with a 27 ohm load, 12 mA is needed to
generate 325 mV swing. Other improvements were made to the driver to further match the drivers output
impedance and to make it contention safe. This has changed the world of backplane driving, the old solution was
to throw more current at the problem (i.e. GTL uses 40 to 80 mA), while BLVDS reduces output current to the 10
mA range.
Today there are three classes of BLVDS parts offered by National. The first is standard transceivers for multipoint
buses. National offers these in single, quad, or nine channel versions. The card connectors, and stub lengths will
limit signal quality in this type of bus configuration to the 200 to 400 Mbps range, which is still an impressive 2X to
4X of single-ended GTL or BTL based systems. The next class is SER/DES devices that serialize data and clock
into a single serial stream. The bus configuration for serial streams can be multidrop (if data rate is less than 400
Mbps) or point-to-point (typically for data rates greater than 400 Mbps) applications. The connector pin savings,
and in some cases fewer backplane layers, can offer huge system cost savings. The third class is special
functions devices. These solve special problems such as bus repeating, redundant path cross-overs, and
crosspoint switches.
BLVDS has addressed a wide market space ranging from telecom infrastructure and datacom to storage
applications where card density demands high-performance backplanes.
Several vendors now offer BLVDS like devices, and its popularity is increasing every day"

PDS: I wonder if Bus LVDS -- would make a good bus replacement for PCI Express -- at least for hobbyist projects where speed -- isn't as important as simplicity and open hardware / open protocols / open standards...
The only account for which I could definitely provide this information would be my work email. It’s kinda of ridiculous to make this part of the criteria for resolving potentially huge disruption to a person’s life.
Funny how "2FA" almost always equates to "phone number".

Beware if they claim they don't store your phone number. It's highly likely they store a hash of it for tracking purposes, and proceed to use child-like logic to claim they didn't break any law in doing so.

Furthermore, data brokers use the same hashing algorithm [1] to connect disparate/separate entities, such as your bank, insurance company, fast food chain, etc, basically, any entity you've shared your phone number/email with, in order to gather data on you behind the scenes. How did that happen, you ask? "Out of sight, out of mind."

Google could restrict non-2FA accounts. That way, users could still access their private collection of playlists, but maybe they're no longer able to make comments.

Google and others should offer a standard palette of 2FA options, where the risk factors are left to the users. Let them choose between verified email, some or other TOTP, but try to avoid scavenging private phone numbers, you know, the highest value, globally unique identifier, ooooh.

Using the preprocessor, something like this:

uint32_t swap32(uint32_t x) { ... }

#if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__
uint32_t swap32be(uint32_t x) { return swap32(x); }
#elif __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__
uint32_t swap32be(uint32_t x) { return x; }
#else
#error "Unknown endian"
#endif

You can make the preprocessor condition broader if you care about more compilers and more platforms. Yes, I'm making assumptions about which platforms you want to target... which is fine. No, I don't care about your PDP-11, nor about dynamically changing your endian at runtime. Nearly any problem in C can be made arbitrarily difficult if you care about sufficiently bizarre platforms, or ask that people write code that is correct on any theoretical conforming C implementation. So we pick some platforms to support.

The above code is fairly simple. You can separate the part where you care about unaligned memory access and the part where you care about endian.

Some irrelevant details left out above.
Yeah - and at least for me this was part of the confusion. The problem is often stated incorrectly.

Critically the host always removes a goat.

If the person presenting the problem just says “the host opens one of the doors”, but doesn’t specify he’s always revealing a bad door then it’s not clear why that matters.

The many door example makes it easy to intuit as well.
Well, I don't know. Advantage moves to the contestant: they close the doors, but everything's gonna remain in the same place. Steathily repositioning an automobile on a soundstage might be possible (albeit difficult), but just you try moving the damn goat
It doesn’t sound like that at all.
I've been a happy SourceHut user since the alpha started back in November of 2018. Although I haven't really used the email-based contribution method because no one contributes to my projects.

I have found that the CI solution is top tier. Being able to SSH into the runner to diagnose your issues is hands down one of the best features to ever exist in CI/CD solutions.

I do have a couple issues with the project however. One of them being Drew is a very "my way or the highway" kind of guy. We live in a world where containerized solutions are pivotal for teams and organizations for better or for worse. SourceHut makes no attempt at being container-friendly. People are left to figure everything out for themselves, and probably would not get much help on the official mailing lists because "it is not officially supported". Up until a couple weeks ago, Drew wasn't even convinced correctly listing out Python package dependencies for each service in the setup.py files was important. Luckily he came to his senses, but I felt was emblematic of his mindset when it comes to software.

I'm hoping that Drew can continue to come around to features that are generally good for SourceHut and people who want to more easily self-host.

I have been paying for this service since the alpha started because I believe in most of what Drew is trying to do. Another great thing I like about SourceHut has been their extremely level-headed approach to any political and topical controversy. They take no position on main vs master, but accepted patches to work much better when master is not the default branch. And they've come out strong against cryptocurrency, which is the same opinion that I have.

2020 was a year of moving to more ethically sound services for me. SourceHut just happens to be one of them. SourceHut sends out monthly updates and quarterly financial summaries, and each email I'm impressed with the growth and outlook of the project.
I'm not denying that programmers get paid a lot or that our taxes shouldn't be higher but it's a different situation from being a doctor or a lawyer. I have no degree and am entirely self-taught. I would not be able to practice law or medicine without getting one. However, I am a professional software engineer.

Programmers get paid a lot because the market is extremely competitive. Doctors get paid a lot because healthcare in the US is essentially one massive cartel and incredibly inefficient as a result. In most countries, doctors and programmers make similar salaries.

> People who stopped doing mathematics had "died", while people who died had "left".

> Music (except classical music) was "noise".

Capital punishments works. Most Asian countries practising that has significant low crimes when compared to USA (excluded the states that do). For example, heavy drugs trafficking and addiction aren't such a problem compare to USA. It is also very cost effective as government don't need to house the prisoners for life. In USA incarcerations are generally outsourced hence a big business, in Asia, this is generally not. Hence capital punishment do works and very effective. So it isnt insane. What you're thinking of insane is because you never experience serious crime and never seen it works such as in Asia context. Things like what commonly happen in John Wicks world and Purge did happen in Asia in the past. It got purged with copious amount of capital punishments. Of course it is always abused by government, China historically used that to purge entire clans (probably few 10s of thousands of people head chopped in one go for each incidents).
IT is typically grossly understaffed and underfunded in these businesses. At the site-level, you'll see some very out of date tech running critical systems. IT is a cost-center to be reduced as much as possible, oversight is non-existent.

- to Jupyter Notebooks (IPy notebooks, but more backends)

Of course this does way more than IPython ever did, or even should do. But it's a pretty funny trajectory, everything old is new again.
Probability of draws:

B then R -> 1/3

B then B -> 1/6

R then B -> 1/3

R then R -> 1/6

Removing the cases where the second draw was R:

R then B -> 2/3

Therefore the first ball being blue has a 1/3 chance.
When you choose the first door, you are partitioning the "board" into two parts: the door you chose, and "everything else".

By opening a door, Monty lets you cover 100% of the "everything else" partition using only one guess.

So now you get to choose between partition 1, which covers 1/3 of the board, and partition 2, which covers 2/3 of the board.
But doesn't that mean it's ultimately in the companies interest?

Unfortunately not, quantum field theory doesn’t explain space time curvature. Nor does GR say anything about quantum effects.
