TIL that Roman Emperor Augustus witnessed a man attempt to feed a slave to lamprey eels as a punishment for breaking a cup. Augustus freed the slave and had the rest of the man's cups broken.

Augustus is a title given to Roman emperors generally. Which one was this now? Sounds like something Marcus Aurelius would do.

I don't know but you can read more about it here.
I liked 'Meditations' by Aurelius. Not bad for a diary never meant to be made public.

It is good to have a sledgehammer, straps, and winch when assembling prefabricated steel structures.

LED stands for light emitting diode. Diodes are effective one way valves in an electric circuit.

I just got an overdrive pedal for guitar in the mail today that has a bunch of LED clipping diodes including purple, red, and infrared 
They are also arranged into 10 different diode combos for versatility. Also features some germanium and silicon diodes which are common in other pedals.
I thought it was really cool LED's are used in pedals to effect the sound, I didn't learn all of that today but some is new to me

TIL that mushroom ancestors grew 30 to 100 feet tall and dropped coconut sized seeds. Mushrooms used to form long thin sheets over water before they learned to live on land, which was of course long before gills or stems or even when polypores and shelf fungus existed.

I love his work.
Begin the morning by saying to thyself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial. All these things happen to them by reason of their ignorance of what is good and evil. But I who have seen the nature of the good that it is beautiful, and of the bad that it is ugly, and the nature of him who does wrong, that it is akin to me; not [only] of the same blood or seed, but that it participates in [the same] intelligence and [the same] portion of the divinity, I can neither be injured by any of them, for no one can fix on me what is ugly, nor can I be angry with my kinsman, nor hate him. For we are made for co-operation, like feet, like hands, like eyelids, like the rows of the upper and lower teeth. To act against one another, then, is contrary to nature; and it is acting against one another to be vexed and to turn away.
Every moment think steadily as a Roman and a man to do what thou hast in hand with perfect and simple dignity, and feeling of affection, and freedom, and justice, and to give thyself relief from all other thoughts. And thou wilt give thyself relief if thou doest every act of thy life as if it were the last, laying aside all carelessness and passionate aversion from the commands of reason, and all hypocrisy, and self-love, and discontent with the portion which has been given to thee. Thou seest how few the things are, the which if a man lays hold of, he is able to live a life which flows in quiet, and is like the existence of the gods; for the gods on their part will require nothing more from him who observes these things.
Men seek retreats for themselves, houses in the country, sea-shores, and mountains; and thou too art wont to desire such things very much. But this is altogether a mark of the most common sort of men, for it is in thy power whenever thou shalt choose to retire into thyself. For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind. Constantly then give to thyself this retreat, and renew thyself; and let thy principles be brief and fundamental, which, as soon as thou shalt recur to them, will be sufficient to cleanse the soul completely, and to send thee back free from all discontent with the things to which thou returnest. For with what art thou discontented? With the badness of men? Recall to thy mind this conclusion, that rational animals exist for one another, and that to endure is a part of justice, and that men do wrong involuntarily; and consider how many already, after mutual enmity, suspicion, hatred, and fighting, have been stretched dead, reduced to ashes; and be quiet at last.--But perhaps thou art dissatisfied with that which is assigned to thee out of the universe.--Recall to thy recollection this alternative; either there is providence or atoms [fortuitous concurrence of things]; or remember the arguments by which it has been proved that the world is a kind of political community [and be quiet at last].--But perhaps corporeal things will still fasten upon thee.--Consider then further that the mind mingles not with the breath, whether moving gently or violently, when it has once drawn itself apart and discovered its own power, and think also of all that thou hast heard and assented to about pain and pleasure [and be quiet at last].--But perhaps the desire of the thing called fame will torment thee.--See how soon everything is forgotten, and look at the chaos of infinite time on each side of [the present], and the emptiness of applause, and the changeableness and want of judgment in those who pretend to give praise, and the narrowness of the space within which it is circumscribed [and be quiet at last]. For the whole earth is a point, and how small a nook in it is this thy dwelling, and how few are there in it, and what kind of people are they who will praise thee. This then remains: Remember to retire into this little territory of thy own, and above all do not distract or strain thyself, but be free, and look at things as a man, as a human being, as a citizen, as a mortal. But among the things readiest to thy hand to which thou shalt turn, let there be these, which are two. One is that things do not touch the soul, for they are external and remain immovable; but our perturbations come only from the opinion which is within. The other is that all these things, which thou seest, change immediately and will no longer be; and constantly bear in mind how many of these changes thou hast already witnessed. The universe is transformation: life is opinion.

Prototaxites were around 420 to 350 million years ago, when land plants were still the relatively new kids on the evolutionary block and “the tallest trees stood just a few feet high,” giant spires of life poked from the Earth. “The ancient organism boasted trunks up to 24 feet (8 meters) high and as wide as three feet (one meter),” said National Geographic in 2007. With the help of a fossil dug up in Saudi Arabia scientists finally figured out what the giant creature was: a fungus. (We think.)
The towering fungus spires would have stood out against a landscape scarce of such giants, said New Scientist in 2007.
“A 6-metre fungus would be odd enough in the modern world, but at least we are used to trees quite a bit bigger,” says Boyce. “Plants at that time were a few feet tall, invertebrate animals were small, and there were no terrestrial vertebrates. This fossil would have been all the more striking in such a diminutive landscape.”
Prototaxites are a genus of terrestrial fossil organisms dating from the Late Silurian until the Late Devonian periods, approximately 420 to 370 million years ago.
I don't remember the name of the >30' ones, but I know they came much later. The species I'm thinking of dropped a "nut" or "seed". You can find them petrified all over Colorado.
Prototaxites would've been the biggest organism on earth, and contain narrow tubelike structures that likely gave rise to the polypore. I believe gilled mushrooms came later.
Glomeromycota* required plants, algae, lichen etc to live and also came much later than prototaxites. They used arbuscular mycorrhizas in the roots of land plants to live.
Mushrooms began in the sea 1.3bn years ago (plants arriving 700m years later). In the meantime, fungus was busy doing the dirty and forming symbiotic relationships (while breaking away from others). They and basic bacteria and algae thus helped terraform the earth, if you will.
My buddy has one of these seeds about the size of a softball (relatively small). I can't remember the species but they're bigger than prototaxites.

it's possible, but i mean these are mostly theories, 420 to 350 million years ago?.. these people are pulling numbers out or their assholes.. we can't say they existed with certainty, can we?..

They're in the fossil record so I'd imagine it's safe to say they did.

Yeah I remember seeing an article about "mysterious giant pillars" that were found to be prehistoric giant fungi. It is definitely a thing I believe.
