> I was very productive, then, using emacs.
"I was never more productive" isn't wrong, and in context it should be clear. But, I read this like "Never, using emacs, did I experience increased productivity".
It reminds me of that trope, "Couldn't care less".
If you want to talk about e^(x) then you're totally free to do that but, you're right: if x is not dimensionless then the expression has no physical meaning (as little meaning as one meter added to one second, as an example of another clearly nonsensical physical function).
In Physics, your starting point always makes sense dimensionally (F=m*a, E=m*g*h) and the game is to combine expressions that make dimensional (and physical) sense to glean insight into how different physical constraints of the system are related.
If you have any Physics problem where you end up with e^(x) or sin(x) and x is not dimensionless then it's a dead giveaway that you performed an algebraic misstep at some point when playing the game.
So, in short, you can propose a lot of functions that make no sense from a physical standpoint, but you won't arrive at those if you're working from first principles which are, by nature, dimensionally consistent.
The unregulated, debased Tether seems less risky than holding regulated, backed-by-real-property mortgage-backed securities in 2007.
It seems much a-do about not much, to me. But, I guess people need something to worry about.
The answer is not clear to me, but it seems like this is an important value.
Also, aren't some of those assets (like treasury bills) interest-accruing? That would seem to offset some of the losses incurred by a short-term, high-volume liquidation event.

All mining is done on earth. Does that mean it's centralized?
I think the implication is that the Chinese government has influence over the currency. If that's true (and I don't think it is, or that they even have any interest, given the rise of crypto capitalism in HK and mainland China) then they could at most attack the network once, completely destroying its value. Sounds like a lot of wasted energy when people can 1) fork BTC to circumvent this 51% attack, and/or 2) opt for another currency to replace BTC as "digital gold".
In my experience, though, Windows 10 has proved really annoying. Over the past 8 weeks,
1) Windows 10 update has broken sound (I occasionally have to disable/enable the Realtek Audio device)
2) Windows 10 update has fixed sound (without seeming to have changed the Realtek Audio driver)
3) Has throttled the performance of my graphics card (hash rate on Autolykos V2 dropped by 10x after an update), without having had changed the graphics driver
4) Windows 10 Pro won't allow certain applications to be downloaded or installed (immediately quarantined) and Virus & Threat Protection isn't visible in the Control Panel. This is a common issue, apparently [1]
Generally, Windows 10 seems to take control of configuring the operating system away from the user while adding a bunch of "telemetry" and "application monitoring". Not too happy. I'm in the process of moving to NixOS as my primary system [2]. I'll boot from a flash drive with a live version of the OS including all applications and files I need for local development; the flash drive will mount the OS into RAM; I'll unplug the flash drive and continue my development from RAM; I'll shut down my machine at the end of the day and have a clean slate the next time I boot into the OS [3].

AFAIK this is the main documentation page: https://core.telegram.org/bots/api which, subjectively speaking is really hard to read, and, objectively speaking, offers no sample responses/interactivity.
This page tries to fill the gap on tutorials/how-to: https://core.telegram.org/bots but without sample code.
There are a few bots you can find on GitHub, but nothing official that I could find.
Documentation on bot limitations in channels vs. groups is also really spotty.
Trying to detect who joined a group/channel and greet them, for example, or trying to send a message on departure, is non-trivial.
The production rate of BTC does not depend on the number of miners as long as there's one miner (with zero miners no BTC is produced). A block is produced every 10 minutes by a computer that produces the smallest hash for a randomly arranged set of inputs (transactions and previous block's hash). This lowest hash serves as an identifier for that block and all input transactions are recorded on the new block with that hash and appended/linked in the chain. Currently, each mined block is associated with a miner reward of 6.25 BTC (I think) that's given to the computer which produced the lowest hash. It doesn't change if there are more/less miners in the network. So, there's no "dry season" just because the mining rate cut in half. There's just less energy being spent competing to generate the lowest hash and get block rewards. So, all the miners not running are failing to potentially earn money and the system is, theoretically, less decentralized, now.
But, there's no change to the rate of production.
