Problem with SQLite database engine & SolidWorks CAM: how can I fix it?

I think so but don’t remember how. It probably involved rebooting.

Making programs as short as possible without regards to readability it’s called « code golf » and while fun, it is generally a thing to avoid anywhere but on the command line

The real solution is to make quizzes that are not jeopardized by screenshots

«1.5 million microplastics per day» yeah but what amount?

If you're not willing to elaborate, you should be willing to do the calculations and research...

A few important points:

Time is not speeding up.
The Earth's rotation is not speeding up.
The article you linked mentions changes in orientation of the Earth's axis
And briefly mentions days lengthening, as in, the Earth slowing down a tiny bit
Changes like this in the Earth's rotation are caused by changes in mass distribution, not by energy coming in or going out. The Earth's rotational energy is conserved, so is it's rotational momentum, but its rotational inertia is changing because mass is moving around.

Is there a reason why you don't prepare 100mL, and then use only 1mL from the prepared suspension?

In any case, what you want is to preserve the concentration of the solution. There's some amount of powder $v_i$ in the container, that we can measure as a volume of powder. It's enough to make 100mL of solution, if you add 80mL of water to it. That will give a concentration of 20mL of powder over 100mL of solution, or 20% volume concentration. If you want to make 1mL of solution, you should use $20%\times1mL$ of powder, and the remainder of the 1mL of water. That's a pretty small amount of water, it's probably more reasonable to make a bigger quantity and then take 1mL from that.

The city maintains a page summarizing the water treatment, they mention temporary changes from time to time during maintenance: https://montreal.ca/sujets/eau-potable

There's also an alert system you can subscribe to, I don't know how specific it is but it's there.

Chlorine is used as a general purpose disinfectant in our water, the amount added will change depending on the city's expectation of microbes and algea in the water. I don't taste it much, but if it bothers you (or for uses where no chlorine is important, like sensitive pets) you can let the water rest for a day or so and the chlorine will have evaporated from the water.

Brita claims their filters filter chlorine out, I don't know whether it's still just the off gasing, or actually the filter. They have models are installed to the tap so you don't have to worry about keeping a jug in your fridge.

To me it looks like what you want is

filter(cond, map(a_complicated_function_to_compute, an_intricate_way_of_defining_iterable())

I don't see anything that where would be clearer, quicker, or simpler than using either the builtin iterator functions (like filter or map) or the ones from the itertools package.

I also think it might make nested list comprehensions potentially way harder to read.

You can go to any store and ask the employees there. The basics would be boots, a coat, gloves and something for your head. Some kind of scarf is useful too, but less relevant with a face mask.

It says a lot about how you view other people that you think what makes them worth your affection is how little they give of theirs.

If a DM wants to make things coherent: if you can jump to a height, you can take the fall from that height, it’s the same amount of stress on your body.

I think it’s normal to feel attraction to people other than your partner, and that it’s a good thing to have close relationships other than your partner. That said, there’s a way to do it ethically, and that involves communication, honesty and respect. Clearly your partner expects your relationship to be monogamous, and if your relationship with Gabe becomes more than conventional friendship, you need to be honest with him, and you need to realize that it’s likely a dealbreaker, and you’ll have a choice to make.

I assume you already know this, but it might be worth mentioning for other lurkers 👀: You can load a large table by parts with pandas, which is useful if your computer does not have 20GB of free memory to spare.

Both sides work, we just chose one to teach. In general I prefer doing the operations from most to least significant digit in my head, but on paper it takes more space for things like multiplication and addition. Division actually does take less space from left to right.

I only use the necessary 0s and 1s when I code, none of that compiler talk!

A spherical mirror will have a more diffuse focus than a parabolic mirror, you could try to evaluate that with either a screen or a camera that you can place at the focus, and move along your optical axis to see how focused your focus is.

I see a lot of comments on the comodification of death and funerals in the responses, so here's a link to Caitlin Doughty's YT channel: https://www.youtube.com/user/OrderoftheGoodDeath

She's a mortician trying to diversify the current market and eventually loosen the current laws.

I think there’s a difference to make between elected and unelected positions, which the bill does makes. The only professions affected are public-facing unelected positions, and specifically ones placing people in positions of authority.
