Not just the protocol makers/devs. Let's pretend you are trying to buy something online with ethereum... (ridiculous of course, who uses these coins to buy real stuff?) You'll have to trust:

* The website you're using (is it a fake clone of the site you thought you were visiting)
* The people that made your crypto wallet (app or hardware, or both?)
* Your computer (lots of crypto stealing malware out there)
* The person/company you are sending money to (are they who they say they are? are they going to just disappear with your coins, since the transaction can't be cancelled)
* The smart contract you might be using (how many bugs are in it, has it got a backdoor to rip users off)
* The miners building the blockchain (it's not just that they don't have to mine your payment - some miners will front-run transactions to do whatever you are trying to do first)
* [...]

But sure, apart from that, it's completely trustless!
it's way cheaper and more humanitarian to secure value in Bitcoin using computer chips than it is to send the US military into foreign countries to support the petro-dollar
> Do you have a source for this? Because from what little I've been able to find, filtration efficiency for particulate in the aerosolized size range are practically negligible with cotton masks and even surgical masks. Which makes sense considering that aerosolized particles are around 2-3 orders of magnitude smaller than pore sizes in cotton and surgical masks, putting such masks in the realm of security theatre.

Pretend that you're blowing out a candle: make a small "stream" with your lips and blow as far as you can. When I do so, my stream can go at least as far out as my arm, which I think is ~1.5 feet or ~2feet or something (longer than that, because my breath is still "strong" at the full length of my arm in front of me).

Now put a cotton mask on and do the same thing. How far does the stream go? Inches, at best.

Note: oxygen, nitrogen, and CO2 are all much much smaller than mask fibers. But you'll find that these things behave as a __fluid__, and thus we have a fluid-dynamics question rather than one of physical objects hitting a screen door model.

------

The distance your breath goes when talking is much reduced. Similarly, the "stream" where you draw in more air is also reduced to a smaller distance when you're masked up.

-----

Or heck, _do_ blow out a candle. This experiment is like, $2. One dollar for a mask, and a second dollar for a birthday candle. Just measure it yourself: the mask grossly affects the distance that oxygen / CO2 / Nitrogen leaves the body.
> You can't. These bikes are DRM'd to the hilt and any attempt at hacking them will cause the bike to brick itself

This does not match reality at all. E-bikes are some of the most modify-able and hackable devices out there. Most of the parts are interchangeable, and a decent portion of these bikes are assembled piece by piece. I can change the acceleration profile of mine at will, via bluetooth. Amperage limits, battery codes, everything. I have used many devices and parts and kits, and have never even once seen DRM present.

Due to the laws of thermodynamics, CO2 and Methane gases diffuse evenly throughout the atmosphere creating a blanket over the entire globe. As we add more gas to the atmosphere, the blanket gets more dense.

In the summer, you probably have a light comforter on your bed while in the winter you probably switch to a heavier comforter. While you're asleep your bed warms up under the comforter and it doesn't cool down until you get out of bed. In the same way, the CO2 and Methane gases are like a comforter that is wrapped around the planet. A low density of gases is like your summer comforter and a high density of gases is like your heavy winter comforter. Unfortunately, unlike your bed, it's not easy to switch from a heavy volume of gases to a light volume of gases -- if it were, then we could terraform Venus. Venus is covered in a CO2 and Methane gas atmosphere so dense that we could float a city on it and the surface is 900degC.
Win10's supported until at least 2025. Not sure why anyone would jump on Win11, unless some software they're using requires it—which seems unlikely for some time, considering how long previous Windows version have retained good 3rd-party software support.

> Windows 11 decreased quite a few user preference/customization options. It's clearly not their objective to do what the user wants, but whatever Microsoft wants (and this is/was one of the few core differentiators for me between Microsoft and Apple, and it is shrinking rapidly).

Huh. I've used Mac for about a decade, after 15 years of Windows + Linux (and some DOS before that) and never felt that Windows is in any sense "freer" than OSX/MacOS, as far as configuration or what I can do with it.
Your Python example is far from idiomatic, though. If a Python programmer were forced to write `Stuff`, they'd write something like:

class Stuff:
def __init__(self):
self.a_list = [1,2,3,4]
def __iter__(self):
return iter(self.a_list)

--- or do what the other person did, and make `__iter__` a generator, which isn't necessary in this case but is much more flexible.
This seems overly complex to me. They have their settings in a .env file, they have a separate program/script that loads those settings into the environment variables, then they have another program that reads them out of the environment and parses them into python objects in settings.py... so why not just put them in settings.py to begin with?

I have also never agreed with the common suggestion of putting secrets into env vars- I believe secrets belong in something like Hashicorp's Vault and stored on the running system using proper OS level access control.

I've been using this at work for the last year or so to great success.

For example, we have an internal phishing simulation/assessment program, and want to track metrics like improvement and general uncertainty. Since implementing this about a year ago, we've been able to make great improvements such as:

* for a given person, identify the wilson lower bound that they would not get phished if they were targeted

* for the employee population as a whole, determine the 95% uncertainty on whether a sample employee would get phished if targeted

It lets us make much more intelligent inferences about things, much more accurate risk assessments, and also lets us improve the program pretty significantly (e.g. your probability of being targeted being weighted by a combination of your wilson lower bound and your wilson uncertainty).

There are SO MANY opportunities to improve things by using this method. Obviously it isn't applicable everywhere, but I'd suggest you look at any metrics you have that use an average and just take a moment to ask yourself if a Wilson bound would be more appropriate, or might enable you to make marked improvements.

Don't. I understood you perfectly well.

I understand the issue just fine, thanks. It's you who didn't understand me. I'll chalk that up to you not being a native English speaker.

I didn't insult you because I felt attacked. I didn't intend to insult you at all.

Rather, I called you out for your nastiness and bad faith. Because you deserved it. And I stand by that assessment.

Re: 3) & 4), Uranium seawater extraction does exist, and it is cheap, easy, and requires very little energy. I toured PNNL and viewed their uranium extraction project in person. It utilizes thin, high surface area fibers of plastic impregnated with a molecule that binds uranium and other heavy metals. A rinse with a dilute acid (acetic, citric, etc) releases the metals. The substrate can then be reused indefinitely.

The deployed system is fully passive - basically fake floating kelp beds, anchored to the sea floor, deployed in high current areas. They would be hauled in every 3 months or so, rinsed off on the boat, and then redeployed. Everything could be done using standard bivalve farming methods, but with lower impact on the environment.

They are now looking at a way to use the same material to post-filter desalination brine.

I am reminded of this famous quote by Leslie Lamport from his article "If You're Not Writing a Program,
Don't Use a Programming Language",

"The programming languages they are now using will seem as quaint as Cobol, and the coding skills they are learning will be of little use. But mathematics will remain the queen of science, and the ability to think mathematically will always be useful."

Seconded. I switched from django-environ to python-decouple. Now that python-decouple defers to environment variables over .env files I find that I have our DevOps people spin up containers with secrets configured using their tool de jure while I just have a local .env file. We just make sure our env.sample is up to date with respect to our .env. DevOps folk use that to define environment variables for the container.

The spatial unit vectors for a 3 spatial dimension [x,y,z] vector are i^=[1,0,0], j^=[0,1,0], and k^=[0,0,1]. These are all said to be orthogonal to each other, which is a generalization of perpendicularity [1] to non-spatial vector spaces.

As a lay person who is not familiar with the mathematics would recognize the term perpendicular, using that in the video is fine.

Contrarian waypoint: beware of not-fast-math. Making things like atan2f and sqrtf set errno takes you down a very slow path, costing you significant perf in cases where you likely do not want it. And most math will work fine with fast-math, if you are careful how you write it. (Free online numerical methods classes are available, eg [1]) Without fast-math most compilers cannot even use FMA instructions (costing you up to 2x in cases where they could be used otherwise) since they cannot prove it will produce the same result - FMA will actually likely produce a more accurate result, but your compiler is handicapped by lack of fast-math to offer it to you.

Screen-zombie pedestrians annoy me as well. So do uneven pavements, trash, rocks and any other obstacles that appear on my way. If I'm on an electric scooter or a bike though it's my responsibility to ensure that I'm not riding a silent, heavy and fast vehicle into someone. Especially if they can't see me because I'm approaching from behind. And to emphasise - there is an entire range of pedestrians that might have a disability (mobility issues, seeing, hearing etc.) which makes them much more vulnerable to accidents.
AFAIK, there is no reason to use the form “for el in self._list: yield el”, unless you are running Python 3.2 or older.

Why not:

each = self._list

Or, if you need to be able to re-assign self._list to a new object:

@property
def each(self):
return self._list

Or, if you for some reason need it to return an iterator:

@property
def each(self):
return iter(self._list)

Or, if you really want it to be a generator function:

@property
def each(self):
yield from self._list

As long as they'r not causing problems for other cyclists, they're still a big win in terms of transportation: way less carbon usage and occupies less space.
Makes sense for seasonal and recreational riders. We both ride year round though almost daily for transportation.

As for discharging below 15%, Bosch's firmware is pretty smart about this. It keeps a reserve that's used for powering lights for a few hours after the assist cuts off.
And the price of ETH is strongly correlated with the price of BTC. So we will see if those GPUs flood the market or simply switch to another crypto.
Oh, sure, I'm making it all up. I just spent two months picking apart the Bosch e-bike system, I think by now I know what I'm talking about but feel free to prove me wrong and show me how you're able to get your battery to talk to a Bosch controller without using a Bosch BMS.

Hint: you won't be able to, the key is embedded in an NXP processor that has it's fuses blown (both sides, controller and battery) and any kind of hacking you want to do will have to be at the sensor level and even there I would advise you to use an older version of the firmware because the newer ones are very good at detecting such hacks.

Oh... I worked with something really similar but only for decoration purposes. I guess it's rigged enough to give the construction stability but it's still very prone to punctures. Do you think it would withstand a rock chip at higher speeds also do you prefer the high mechanical stability for a battery package? I don't really know if I would prefer it to warp at impact or break like hpl.
Why not? There's tons of reasons to do it, other than craving attention. I'm really enthusiastic about the tech I do, and I like to share my enthusiasm. Also, it helps to lend credence to what I say, if I can back it up.

The reality is that there is no useful bright-line rule to distinguish between bicycles and motorbikes. Historically, the two have been very distinct, so we haven't needed one. Now, we are starting to see more of the space between the extremes be explored.
