You cannot build up an immunity to cyanide. The mechanism of action for it to act as a poison is that it directly limits aerobic respiration on a molecular level. To put that more simply, it stops oxygen from getting where it needs to go and effectively stops your cells from "breathing", ultimately stopping your mitochondria from functioning. To put that in a more complex way, it binds to part of an enzyme called cytochrome c oxidase that is essential to ATP synthethis and prevents the reaction from occurring.

Horrifyingly, cyanide poisoning cannot be fixed by simply giving the body higher concentrations of oxygen to breathe in. It doesn't prevent your repository system from uptaking oxygen. Instead it prevents your individual cells from using the available oxygen.

While it is sort of technically possible in the case of cyanide for the liver to produce more rhodanese (an enzyme that specifically reduces the toxic effects of cyanide in the body) the reaction is dependent on sulfur. Perhaps if you ate foods like eggs in very large quantities and also regularly ate larger amounts of cyanide you could maintain a state of immunity to doses larger than what would normally kill a person but I can't find any evidence of someone stupid enough to test that. Regardless this immunity is in the form of getting your liver to simply clear the cyanide from your system faster and does nothing to stop the underlying cellular asphyxiation.

As an aside Arsenic which was also mentioned earlier interrupts mitochondrial function as well, but in this case it takes the place of Phosphorus (The P in ATP) and the resulting molecule is not able to react correctly. While not a perfect comparison you can think of cyanide as starving your cells of oxygen while arsenic starves them of useful fuel. Neither of these are something you can build an immunity to.

Am officially maintained Docker image is no less a security concern than an officially maintained apt repo. Depending on how you set up a container stack it can even be more secure. An attacker gaining root access to a container that you've given extremely selective access to the host machine is far better than them gaining root access to your actual system.

He does a quick calculation in the video and concludes that in this case it was ~176KB of uncompressed information, working out to about 2 MiB/s of bandwidth given that time it took to sing out the data.

I ran a microbiology lab that specifically tested for food borne illness causing bacteria.

Here's a very recent attempt to assess the safety of cold brew coffee coming out of UGA. https://newswire.caes.uga.edu/story/10365/cold-brew-coffee.html

These findings line up with earlier work such as this paper doing a general analysis of cold brew coffee and this Canadian government report on detected food borne pathogens in cold brew coffee..

The consensus I'm seeing is that cold brew coffee, especially when kept cold, is not a great environment for most food borne illness causing pathogens to thrive. Bacillus cereus and potentially botulism would have been more accurate choices.

The logic isn't flawed, your priors are. You're assuming that people are constantly on a cycle of charging their battery to the limit, running it down low, and then charging it again. If you mostly play docked or with a charger plugged in then capping the battery at around 80% prolongs the battery runtime for when you do turn the limit off and want to use the full battery.

If you mostly play fully charged and stationary, then lowering the charge limit means you have more future opportunities to experience the fully battery runtime when you disable the setting.

Google's speakers have had local voice processing for basic commands for years now. Things like toggling power on lights or changing TV volume. They're also expanding that locally processed control into then being run through the Matter standard so the whole chain is done locally. I have personally verified the local processing on my own network traffic.

In God We Trust is also an objectively less cool motto than e pluribus unum which translates to out of many, one. We traded the original ideal of a people united by difference into a boringly generic religious proclamation just to try to stick it to the commies.

The average human has somewhere between 1.1 and 1.4 testicles.

Late edit: I was not sober when I wrote this and I definitely did the math wrong.

The modern definitions of units feel even more arbitrary because they are inextricably tied to more organic origins. Consider the often made fun of fahrenheit scale which was the first to define a reasonably repeatable degree size by using two widely available reference points as the 100 and 0 ends of the scale, human body temperature for the high end and an ammonium chloride ice water mix for the low end.

The definition of a second was a bit jankier. Etymologically the name comes from a second hand added to a watch face to give some kind of indicator that the minutes are passing by. NIST has an excellent writeup on this subject. Over time different repeatable ways to measure a second have been determined all with the goal of having some action a human could use to calibrate their device's second measurement to so their seconds are as long as everyone else's.

The point is, we didn't choose a second to be defined as some number of atomic oscillations. We had an already agreed upon definition of a second that used less precise methods than modern technology demanded and used a natural phenomenon that could be very accurately measured to make a less arbitrary definition.
