Unshielded embedded systems generate RF noise that can be received on AM/FM radios. Some devs figured out which processes generated which noises and could determine what the system was doing, or if a loop was taking too long just by listening.
Fun lists but the "1 tile = 1 point" needs more realistic weights - for example "take a video" is equivalent to "make a short film" in points earned, where realistically pushing a button is not the same effort as making a short.
Maybe there should be a logarithmic/exponential/multiplier scale associated with progressing up the list.
Or determine an average time-to-complete metric from user feedback and indicate such on the skill progression.
You can see ancient agave roasting pits in Anza-Borrego Desert State Park, if you know where to look.
Also, if you've ever run over an agave with a lawnmower while wearing shorts you'll soon experience a burning sensation on your legs, so props to folks that handle the leaves without issues...
I helped my mom transplant a large agave plant and got in contact with a considerable amount of sap in the process — it's extremely uncomfortable and it took probably 3 months for the resulting rash to go away on my inner arms.
The irritation comes from raphides [0], which are sharp calcium oxalate crystals that get into your skin. Definitely something to avoid if you can! I have no idea how folks work with bare skin around those plants...
Interestingly, pineapples and kiwis have raphides in them as well, so if your mouth feels cut up after eating some, that is why.
The “cut up” feeling that can occur after eating kiwi or pineapple is more likely to be caused by the natural proteases present in the raw fruit (actinidain and bromelain, respectively) as the “cut up” feeling generally does not occur in cooked or canned fruit due to denaturing of the protein proteases. Raphides, which are sharp, insoluble calcium oxalate crystals, are generally not destroyed by boiling (as stated in your link) as so would still be present in the cooked fruit, suggesting that they are unlikely to be responsible for the “cut up” sensation.
Fascinating! Agave looks a lot like Aloe, but apparently they're not closely related. I wouldn't expect looking at an Agave for it to be a skin irritant.
The bridge in the thumbnail is the Coronado bridge, rumored to have a floating hollow-box mid-section so that in the event of a collapse Navy ships can easily push debris and clear a channel. I remember hearing this "fact" on a San Diego harbor cruise long ago. Alas Wikipedia says it's a myth...
