+1 for MoCA
I switched from powerline to MoCA about 10 years ago, and it was a huge step up. Even though it’s half duplex, since MoCA version 2.5, there is enough total bandwidth available to sustain 1 Gbps in 2 directions simultaneously, so it is functionally almost equivalent to full duplex 1 gig Ethernet (except for few ms of extra latency)
Fun fact, California doesn’t mandate safety or roadworthiness inspections for personal vehicles at all - only emissions.
This was a bit of a surprise to me when I moved here, given CAs reputation.
To differentiate it from O - making 0 narrow is a common way to do that

For most citrus the pith has no flavor at all, definitely not bitter. Most people object to the texture and blandness/lack of flavor, which I can understand. I have a bunch of citrus trees in my yard, and learned to not mind the pith, mainly due to laziness (I eat a lot of oranges) - and it’s a good source of fiber.
Western diet is actually notoriously low on fiber and high in sugar, and the citrus pith is also high in vitamin C.
So for many people eating the pith would actually be a healthier choice - in the context of their low fiber/high sugar diet.
I first got on the Internet just as the shift from :-) to :) was happening, only geezers still used :-) and :) was the hip new thing…

14·10 months agophotography might be an area where digital hasn’t caught up, since film’s resolution is down to the molecular level
Film resolution is limited by the size of the silver halide crystals that make up the light sensitive layer of the film. Crystals can come in different sizes, but their sensitivity to light depends on their size - generally you need pretty large crystals for usable photographic film, somewhere between 0.1 and 10 microns (depending on the film ISO rating) - about 3-5 orders of magnitude larger than what you would consider molecular scale.
When the film is developed the crystals are visible as film grain limiting the resolution in some ways similar to pixel size of a digital camera (although there are differences, since the crystal size is not completely uniform but rather has a specific distribution, creating a more random effect than the regular pixel grid of digital cameras)
The pixel sizes on modern high resolution digital camera sensors are actually similar, down to 0.5 micron. It’s hard to make an exact comparison, but I have seen estimates that you need a full frame digital sensor of somewhere between 10 to 50 megapixels to equal the resolution of 35mm ISO 100 film.
And modern sensors are much more light sensitive than film, which allows you to shoot more optimally and give you more flexibility (less exposure time, potentially higher f-stop with better lens resolution, lower ISO, less light, etc.) and therefore achieve potentially better results in more conditions. Add to that the hassle and costs of working with film, and most professional photo work is now done in digital as well. Film is generally only used for stylistic purposes, by purists who are not satisfied with digital simulation.
But your citation gives both statements:
“In fact, the monkey would almost surely type every possible finite text an infinite number of times.”
and
“The theorem can be generalized to state that any sequence of events that has a non-zero probability of happening will almost certainly occur an infinite number of times, given an infinite amount of time or a universe that is infinite in size.”
So when you say the number of times is “unknowable” the actual answer is “almost surely an infinite number of times” no ? Since the probability of that can be calculated as 100%. The mindfuck part is that it is still possible that no monkey at all will type a particular text, even though the probability of that is 0.
The probability that only 2 monkeys will type the text is also still 0, same as 3 monkeys, 4 monkeys, etc. - in fact the probability of any specific finite number of monkeys only typing out the text is still 0 - only the probability of an infinite number of monkeys typing it out is 100% (the probabilities of all possible outcomes, even when infinite, have to sum up to 1 after all)
We just know that it will almost surely happen, but that doesn’t mean it will happen an infinite amount of occurrences.
Basically, if we know “it will almost surely happen” then we also know just as surely (p=1) that it will also happen an infinite number of times (but it might also never happen, although with p=0)
Ok, this is interesting, so thanks for pointing me to it. I think it’s still safe to say “almost surely an infinite number of monkeys” as opposed to “almost surely at least one”, since the probability of both cases is still 100% (can their probability even be quantitatively compared ? is one 100% more likely than another 100% in this case ?)
The idea that something with probability of 0 can happen in an infinite set is still a bit of a mindfuck - although I understand why this is necessary (e.g. picking a random marble from an infinite set of marbles where 1 is blue and all others red for example - the probability of picking the blue marble is 0, but it is obviously still possible)
That’s the thing though, infinity isn’t “large” - that is the wrong way to think about it, large implies a size or bounds - infinity is boundless. An infinity can contain an infinite number of other infinities within itself.
Mathematically, if the monkeys are generating truly random sequences of letters, then an infinite number (and not just “at least one”) of them will by definition immediately start typing out Hamlet, and the probability of that is 100% (
not “almost surely”edit: I was wrong on this part, 100% here does actually mean “almost surely”, see below). At the same time, every possible finite combination of letters will begin to be typed out as well, including every possible work of literature ever written, past, present or future, and each of those will begin to be typed out each by an infinite number of other monkeys, with 100% probability.
But it also works with infinite number of monkeys, one will almost surely start typing Hamlet right away.
Wouldn’t it even be not just one, but an infinite number of them that would start typing out Hamlet right away ?

2·1 year agoLOX is liquid oxygen, which is not a fuel, but an oxidizer. Starship is fueled by liquid methane. Methane can not be made from just water, you need a source of carbon. On Mars for example methane could be produced from CO2 in the atmosphere and water from ice.


This is only partially true. Very early on, this was the case - Chinese characters started as pictograms representing objects and concepts. But this was fairly limiting in how much complexity you could capture without creating an unmanageably large set of unique pictograms. So the system evolved to use compound characters (characters made up of 2 or more components) incorporating phonetic (i.e. pronunciation) information into the writing system.
Most Chinese characters used in past 2000 years are made up of parts related to their meaning or category of meaning, and parts related to the pronunciation of the spoken word they represent (at least at some point in time, typically in Old Chinese) - these are called phono-semantic compound characters. The first comprehensive dictionary of Chinese characters that was created almost 2000 years ago already classified over 80% of all characters as phono-semantic compounds. This percentage also went up over time in later dictionaries as new compound characters were still being added.
As an example the character for book (書) - is made up of 2 parts, the semantic part is 聿 (brush - in its original form a literal picture of a hand holding a brush) on top (so the word is related to writing or painting), and 者 on the bottom (the meaning of 者 is not important here (it was a picture of a mouth eating sugarcane originally, but lost this meaning long time ago), but 者 in Old Chinese was pronounced similar to the Old Chinese spoken word for book, so it serves a purely phonetic function here)
When Chinese writing was adopted in Japan, it wasn’t really used to write Japanese - it was used to write Classical Chinese. Literate people would translate from Japanese to Chinese (which they would have been fluent in) and write it down in Classical Chinese grammar and vocabulary, not spoken Japanese grammar. They could also read it back and translate on the fly into spoken Japanese for Japanese speaking audience. They also brought in the Chinese pronunciation of the Characters into Japanese (in fact several different versions of this over time - see Go-on, Kan-on, etc.) so the phonetic hints in the characters were still useful when learning the system.
Attempting to write spoken Japanese using Chinese characters was difficult, initially they would actually use Chinese characters stripped of their meaning to represent Japanese syllables. These were later simplified to become modern kana
Spoken Chinese itself evolved beyond the monosyllabic written Classical Chinese (which remained quite rigid), so for a long time, Chinese also wrote essentially in a different language from how they spoke. It was only fairly recently that vernacular Chinese began to be written (rather than Classical Chinese) with it’s polysyllabic words (most words in modern Chinese have 2 or more syllables, and require 2 or more characters to write, further distancing modern words from the original simple pictogram meanings)
So while the idea of some kind of universal abstract concept representation divorced from phonetics sounds intriguing, in practice it is a poor way to capture the complexity and nuance of spoken languages, and all languages (including Chinese) that attempted to adopt it ended up having to build various phonetic hints and workarounds to make the system actually useful and practical for writing.
