also

a few other observations from china:

in developed, urbanized places, people live, or aspire to live, in flat, spread-out places (single-family houses in subdivisions, or in the countryside); and they go to work in tall buildings in concentrated, densely-built places.

in developing, urbanizing places, people live, or aspire to live, in tall buildings in densely-built places; and they go to work in flat, spread-out places (factories, construction).

all i noticed was that in china, even in small towns, once you get out of the little villages (where each family has a house of their own), the common people live in tall apartment buildings or highrises, but a lot of them are going to work in huge factory floors, although a lot of them are also going to commercial or service-sector stuff in big multistory buildings. meanwhile in the US, common people (except for young people starting out, or the urban poor, or anyone living in a big city downtown) live in houses surrounded by open space, but they tend to go to work in service sector or commercial business in tall, downtown buildings, although many are also going to work on factory floors. so, it's not a perfect 'economic chiasmus', but still an interesting little contrast.

also, this happened several times: after using the second floor bathroom, i would stand by the window to reassemble my multi-layer winter clothing, looking outside through the blinds. across the street, i would see the front window, at ground-level, of another house, with white curtains drawn. just in front of the window was a little tree with what i think were seed pods hanging from the branches, so that i saw the branches against the window curtain background. each time i saw this scene, i at first would think that the curtain had large-print calligraphic characters printed on it, only to shift immediately to seeing the true depthful scene - deja trompé! even after the shift, there would still be a lingering feeling of 'what are the characters, they are too small to read', which would then quickly disappear as it was obviously a wrong question. it did make me wonder whether or not the same sort of scene had stimulated some artful styles of calligraphy..

dinner aura

(this and the previous post were written as dated, but are posted today, 1-5-13; the times are today's time).

last night, just as we were starting our saturday night banquet, i noticed that everything i was looking at seemed distorted, and then realized that a scotoma was developing, just below and right of fixation. i wasn't able to pay much attention to this one, since i had to eat dinner without looking like a lunatic, but it seemed normal; straightish out to the right of fixation, then arcing downward. there was a period early on where the scotoma was very difficult to find, but i think it was just distributed, or at least not exactly the same in both eyes, but was still there. whereas usually the headache would have started about halfway in, this time there was nothing; maybe a slight sense of headache-like pressure behind the forehead, but no pain. i am guessing this was maybe due to the constant alcohol ingestion? by the time the 10-15 minute mark came around, i had probably had at least 2 shots of baijiu.

absence of a headache was good, since following this i went with jp's father, uncle huang, and uncle wang to get my 'feet washed', which really turned out to mean a full-body massage. a full-body massage while fully dressed in winter getup, sweaters and pants and long underwear. it was nice, though! and lucky no headache, since there was a stage of head-beating.

also, i didn't detect any sort of prodrome. in the morning, i had felt it inordinately difficult to form sentences, and made some strange mistakes in chinese, producing strangely wrong words, which i noticed at the time as out of the ordinary. otherwise, nothing obviously in prediction..

random observations:

(rambling chinese vacation edition):

1. due to jet lag, woke up at about 5:30am yesterday, lay in bed for ~1.5hrs. of course a thousand random thoughts ran through my head, but for a while a lay there watching the augenlicht. long, long ago i noticed how it cycles: against the dark, reddish-black background, a brighter cloud coalesces around the fovea, then fades, then coalesces again. the cycle is somewhere between 5-10 seconds, the cloud is a very low-frequency modulation (maybe ~5degrees across) of the high-frequency noise grain.

what i noticed yesterday was that as the cloud fades, some parts of it seem to 'stick'; this is hard to describe. imagine that the cloud was displayed on a screen, and that its brightest parts, around the peak, were 'clipped'; then, as the could fades, the clipped parts persist, then brighten noticeably, then dissipate as the cycle continues. the impression is similar to a very bright afterimage floating in front of a fixated object, except that my eyes were closed, and i was certainly dark adapted. the clipped portions are sharp-edged, small (half or a quarter degree across), with the spatial appearance of little interconnected droplets of a liquid. i wasn't able to tell if they had the same structure on each cycle, but it seemed that they did.

i cannot guess meaningfully what this is. some sort of pattern formation machinery being stimulated by the structure of the cloud cycle, which has a slower decay constant? it seems familiar, so i might have noticed it at some other time in the past when i found myself lying in bed, unable to go to sleep. when i was in college, that happened a lot, because i would have classes in the morning and force myself to bed, despite wanting to stay up until 2 or 3, and so i'd lay in bed for hours sometimes, waiting to sleep.

i also noticed that i could very clearly see the 'eye crank lines', especially when looking down, whereas usually i can't see them when my eyes are closed.

2. when we finally got out of bed yesterday morning, discovered it was snowing. it eventually stopped snowing and started raining, so the weather yesterday was miserable. still, we drove down south to visit family. we went to visit j*'s father's older sister, who i'd never met before, in a village in another corner of fanchang; her home was like something out of a fairy tale, not so surrounded by garbage and chaos like some of the other villages (which are still nice to visit, don't get me wrong). i had jingping take some pictures. there was a mountain running up directly on the side of the village, with a bamboo forest; spread out away from the mountain and the village was a large expanse of vegetable gardens. we had lunch cooked on a wood stove (and with some electricity). i hope that china is able to keep from totally losing this world as it moves on into the future.. all they really need is to find a way to deal with the garbage.

on the way down there, we drove on a new highway which took us through several tunnels beneath the mountains. at some point, to the right, in the distance, maybe a mile or so distant (in the south of wuhu, there are mountains and there are flat plains, and stark, sudden transitionsn between them), through the snowy, rainy, smoggy haze, i saw a massive building, seemingly in the middle of nowhere. it looked like something in DC; the size of the pentagon, ten or twenty stories wide, sixty stories wide. then, a little further south, a gigantic factory or processing plant, like a refinery or the biggest concrete plant you've ever seen. then, a mountain. i didn't bring the GPS to track where we went this time, but i can probably figure it out from memory. this reminds me of last year, something i never wrote down; on the bus back to shanghai, in the distance i could see a glowing tower, probably a hotel, surrounded by nothing else. it was probably fifty stories high, and surrounded by what looked like a 4th or 5th-tier town. maybe we'll see it again this time, since we're probably taking the same bus back.

also on the wuhu note, i've noticed lots of songbirds here in the subdivision, first time in four winters. maybe whatever drove them away is getting better?

3. dinner at uncle's restaurant. dog meat tastes weird. it was worth a try.

4. still on the roman history kick, been reading Tacitus' history of the 'year of four emperors', on the civil war that commenced with the death of Nero. it really is great reading. in the section on Otho's last stand and suicide, i paused for a while and thought about how all this had happened. i still don't know much about roman history, but i've read livy, so i know something about the beginnings of the republic and how it came to be; and i've read plutarch's lives of marius, sulla, crassus, pompey, and caesar, so i kind of understand how the republic cascaded into the empire.

i thought, the romans had all these lawful institutions for separating power, trading offices more-or-less peacefully and agreeably, avoiding autocracy and civil wars. they kept this up for hundreds of years, but only because to have faltered would have probably meant the end of rome, because there were still so many other powerful players in the vicinity. only after those players - the etruscans, the gauls, carthage - were subjugated, only then could the internal struggles really commence. the rise of the emperors, through the disruptions of marius to caesar, put an end to those struggles by ending all the power sharing. but that meant that once an emperor had failed, the struggles would flare again, and there would be civil war. the situation described - and witnessed first-hand - by Tacitus was the first of several times that this would happen, and it would eventually bring the end of the empire.

so i thought all of that, putting together the pieces that so many others have put together so many times, and then i turned the page, and Tacitus himself begins a digression where he outlines the same reflections on the same reasoning, and again i was impressed at the immediacy of reading the thoughts of a person who lived and died more than 1800 years ago.

5. despite the preceding item on how great Tacitus is, i switched yesterday (at the beginning of the next book of Tacitus, on Vespasian's rebellion) to reading Darwin's 'on expressions of man and animals', or whatever the title is. i've wanted to read this for years, never got around to it until there it was, Free on Ibooks. reading Darwin is great because of the way he makes his thinking so transparent; he explains everything iteratively, first in broad terms, then more and more specific, each time tacking on anecdotes or examples with more and more density. origin of species and the descent of man were written similarly, spiraling down from general statements to specific demonstrations, with examples at every level, but there was less anecdote; here, Darwin is on every page noting a story from some friend or acquaintance, or describing the behavior of his own dogs or farm animals. so, the story is solidy anecdotal, but still convincing, because you can see how he is being led at each stage to a question; if such-and-such is true, we should observe this, and here is an example that we all know, or an anecdote that i'm sure you'll recognize (e.g. how a dog acts when in anticipation of something he likes).

i also like all the talk about "nerve-force". the idea that this nerve-force overflows from the channels of immediate use, into channels of frequent or necessarily convenient use, and only later into less frequently used channels, is important in a lot of his examples. also, his 'principle of antithesis' in explaining some expressions is, i think, an interesting example of something more general than an adaptation aftereffect. for example, the excited dog, when it finds that it will not get what it expects, will look dejected - the 'hot-house face' - with this expression explained as, essentially, the aftereffect of adaptation to an excited manner. i think i will look more into this idea of antithesis in behavior..

unifications of china 1

Random idea from this weekend: create a set of spatiotemporal maps illustrating the unifying conquests of China. For fun. Let's make a list:

1. Qin: Ying Zheng and Guanzhong
Qin was one of many Warring States in the centuries leading up to the first true unification of China in 9780HE. Qin was based in the area around and to the west of Xi'an, which is protected by mountain ranges and accessible only through narrow passes (I traveled through the Hangu pass to visit Xi'an in 12010HE): hence the region's name of Guanzhong, "within the passes". The conquest has an ill-defined starting point, since the different states had been in contention for centuries. However, it was with Ying Zheng's rule that most of the work was done: between 9771 and 9780, China proper went from seven states to one. This period, the Qin Unification War, could be taken as the first.

2. Han: Liu Bang and Guanzhong
Qin didn't long outlive Ying Zheng, who died in 9791. Soon after his death, Qin was overthrown and broken up into a number of kingdoms, united in theory by the Emperor of Chu, who was in fact a puppet of the warlord Xiang Yu. Xiang Yu's confederation quickly disintegrated into civil war between Xiang's Chu state and Liu Bang's Han state, which lasted from 9795 to 9799, when Chu was finally defeated and absorbed into Han. Han, by the way, based its power in the mountain-protected cities of Hanzhong and Chang'an, as Qin had done. Xiang Yu had placed his capital in Pengcheng, in eastern China. This war, and its result, was messy: at any given point in time, even for a decade after the war ended, it was unclear just who was in charge of particular regions, and a lot rested on the proclaimed allegiances of one or another warlord. However, there are standard interpretations of who was with who and when, that could be used to clarify an illustration.

3. Wei/Jin: Cao Cao and Guandong (east of the passes)
Han lasted for 400 years. When it finally collapsed around 10190, there were more than 20 years of war, followed by a half-century period of fracture into the Three Kingdoms of Wei, Wu, and Shu. The Wei state, based in the western edges of the central plains, just east of the mountain strongholds favored by Qin and early Han, eventually conquered Shu in 10263, was replaced in a coup by Jin in 10265, and finally conquered Wu in 10280. After this, Jin slowly fell apart, and China wouldn't be put together under one government again for another four centuries. The Wei/Jin unification was so slow, taking more than 80 years, that it can't really be considered a 'conquest'; it was a slow succession of local wars, with long spaces of quiet in between. I don't think this one would count.

I don't know much about the establishment of Sui - we'll wait until I've read a bit more on it before I continue.

chinese american economics II

during this year's China trip, Jingping and I had a few discussions re the issue of $-元 exchange rate, and I noticed a few more points.

so, the Chinese state controls the international value of the RMB, for reasons including the cycle explained in that previous post. i didn't state there that there's a special factor making that cycle necessary, factor being that exchanges are only possible through government-controlled agencies (i.e. Chinese banks, which are all state-run). the Chinese state is slowly allowing the value of the RMB to appreciate, by a few percent a year over the past few years, because they recognize that the power of the Chinese economy has outstripped the exchange rate.

in other words, Chinese labor and land - i.e. export - is no longer as cheap and plentiful for foreigners as it used to be, and foreign labor and land - i.e. import - is no longer obviously prohibitively expensive. the Chinese don't want to damage their export system, and they don't want to get overwhelmed with a whole new system of imports, so they're making the RMB adjustment very, very slowly.

this isn't what I noticed, though. this trip, the topic of American investment kept coming up, especially in the context of wealthy Chinese sending their high school or college age children to study in the US. this must be barely affordable even for the upper-middle-class Chinese that are doing it, because private schools in the US are expensive even for Americans. the skewed exchange rate makes it even more expensive, probably by a factor of 2 or more.

on top of this, Jingping's parents gave us a good amount of money to use for her optometry school bills; this is money that they otherwise would have lent to people in China for a small return. they recognized that Jingping taking a large US loan ("financial aid") and paying a large amount of interest would be more costly than giving her the money and thereby giving up their Chinese interest. but, it's still a loss this way, because simply by moving the cash to the US and waiting any meaningful interval of time, the value of the money will decrease.

you can think about this more generally, and in bigger numbers. moderately wealthy Chinese, i.e. those just above Jingping's parents, have enough to invest in their child's education, accepting the exchange rate loss because, well, it's their child. but for the very wealthy - which in China often means state officials, investment abroad means business interests. wealthy Chinese own property abroad, have money in foreign accounts which they use to do international business. they do this because of the operational freedom it gives them, and because their profit margins must be larger than the decline in value of the foreign currencies (i.e. $$) they're using.

but if the drop were too fast... the foreign calculations wouldn't change, and business might actually pick up a bit if it had any connection to markets that were now becoming available to Chinese spending. but for the wealthy Chinese controlling those businesses, their domestic profits could drop precipitously. they might even lose money in the short term.

so, it's not just about protection of the Chinese export economy, or protection against foreign export economies; it's also about protection of domestic profits from profits on foreign investments.

Wuhu Environs


About five hundred kilometers upstream from the Pacific, the River runs east and then abruptly north. Sprawling eastward from the northern arm of this right angle is the City of Wuhu. The main body of the City is pressed up against the River, which is still the region's main artery for trade, though in turns railroads and now highways have added new arteries, enabling the City to sprawl away from the River in new directions, and to mix its influence with its neighbors.

To the south, the City begins to wrap around the River bend before it fades into farming villages and the occasional satellite towns that sit between and around the tips of the northernmost foothills of the Yellow Mountains. My wife was born in one of these towns, and her parents in another smaller one nearby, the two towns separated by a long fragment of those foothills, a little mountain with a northward spine. Her ancestors are buried on the slopes of that mountain.

Eastwards, there are marshes which have been engineered over centuries, or millennia, into networks of polders, surrounded by channels filled with water from distant rivers, on each of which sits a tiny village or a cluster of tended fields, or both. Some of these networks are regular, laid out in vast grids tens of kilometers across, showing from any vantage point the mark of some overarching plan, carried out long ago by the people of those marshes. Others follow no obvious pattern, except that there seems to be some average island size, similar to that constant size of the regular networks, and some acceptable deviation from this average, and an agreement amongst the people that they were going to reform the marshes into channels and islands.

Surrounded and out of options, the Hegemon Xiang Yu is said to have killed himself nearby, two-thousand two-hundred and fourteen years ago, and someone is supposed to have taken his horse's saddle up onto a mountain and buried it. That mountain gives its name to the City of Ma'anshan, which also presses up against the east bank of the River, fifty kilometers or so north of Wuhu. This City is known for making steel, and a ride through town will show you infinite smokestacks and gray air that covers everything, it is beautiful and terrible all at once.

Further north along the course of the River is the Southern Capital, and from there the River makes its final drive east where it breaks apart and becomes Shanghai. Across the River bend from Wuhu, north and west, is Chaohu, which has recently been dismembered by its neighboring Cities, most notably the provincial capital of Hefei, which sits even further along the same northwest vector.

Westwards, up the River, there is more, Hubei and Jiangxi and beyond, but there is more in every direction, and the mind follows the flow of the river back towards the Ocean in the east, and does not easily run against it, and these are enough reasons now to conclude and say that the City rules the neighborhood of that bend in the River.

chinese-american economics

unrelated to the internet, but i did realize this last night, so it may as well go down here.

i'm aware of two facts, to which we are all constantly exposed by various media:

A. the US buys lots of stuff from China, more than China buys from the US, so there's a trade imbalance. this means the Chinese are stuck with extra $$ that they can't spend, so they loan it back to the US to continue the cycle.
B. the Chinese 元 is tied, in part, to the US $$.

i knew these things already, but didn't realize they were directly related. but they are - and so far i think it's a one-way relationship, in that A) makes B) necessary. i understood it in terms of the following cycle:

1. China companies manufacture goods
2. US companies purchase China goods with $$
3. China companies purchase US goods with the $$ they accumulated
4. China companies have $$ leftover
5. China companies need to pay for domestic costs and profit, but can't spend $$ in China
6. China companies give their $$ to China govt, which gives them China 元 in exchange
7. China govt loans $$ to US treasury
8. US treasury loans $$ to US banks
9. US banks loan $$ to US companies
10. (back to 2.)

this seems to work. I don't know anything about how sustainable it is, though I think I see how you could get to know, or have a strong opinion about, something like that by looking at this process in detail.

anyways, why does A lead to B? because of 6). in order for 6) to be a fair deal, so that the China companies can know they're getting exactly their dollar's worth in the trade, the $$ and the 元 should be closely linked. in essence, those $$-linked 元 are like $$ printed in Chinese form, with the actual $$ stored away as ensured value, like gold - this is why they call $$ a reserve currency.

so apparently, this journal is entirely devoted to me figuring out things that everyone else knows already.

China 222 part 2

And, got scanned again by 222.45.112.59, on ports 8085, 2479, and 8090.

China 222

maybe a better name for this log should be "what random thing did i see today".

1. it's hard to type in a wrist brace. that fits with "what did i learn today", so..

2. saw four packets from China, from address 222.45.112.59. they soaked into 4 ports which i lost because i restarted the monitor - got distracted at the wrong time, lost good information... i did scan the address and found that it may be a server - google indicates it could be a proxy server: open ports on 1026 and 3389. note comments here and especially here. apparently multiple Chinese IPs starting with 222 are pushing scans all over the place, irritating lots of people.

portsweeping

this is called portsweeping!

i saw another one, in China (Jinan, Shandong maybe), this one looking into port 6000, which can be used for remote keystroke recording.

somebody just sets up a program to search the internet for computers with vulnerable ports. it's like if someone could go and scan apartments for ones with unlocked doors or open windows - then send in the thieves! amazing!

MS WBT SERVER

watching the net monitor again, with network applications turned off. saw one unassociated address - tracked down to Henan, China. to look this up, i stopped the monitor and opened the web browser. then i started the monitor up again, and right away realized i had failed to check the port number.
luckily (or unluckily) i caught another one. this one was either in Georgia (.ge) or Turkey - i think the service is based in Turkey, but the address was in Georgia.

so, this address exchanged several TCP packets with my computer, none of which seemed to contain anything (i say this only because they had 'payload lengths' of zero - this is not something i have researched yet). they were exchanged through port 3389, which actually carried a label: MS WBT SERVER. what is MS WBT SERVER you ask? this is the port used by the 'Remote Desktop' utility in windows. obviously, this was something in the Caucasus searching for a computer with a somehow vulnerable port 3389.

how to tell if it's vulnerable? maybe if i was using the utility? i don't know. maybe he's watching me type right now, though i think then i'd be able to see him still. it was a total of 8 TCP packets, followed a couple of minutes later by 2 UDP packets.

very interesting!
