Blue hour in the hills

I had a pretty long pause with photography, since I was in a heat wave that doesn’t really encourage going out with a camera unless you really want to have a heat stroke, and it’s also a tourist season where everything’s crowded and I hate that.

Also, spending karma in industrial quantities is about as much fun as it sounds, so I wasn’t in a mood for anything really. I was processing that shit, trying not to go crazy too much, and eating too much food because I was at home and stressed out.

Recently, I figured out that if I climb the local hill, which is basically the top of the island, the temperatures are manageable even during the summer if I start late enough, and return in the deep dark of the night. Of course, once we get high enough to get out of the heat and the crowd, photographic opportunities start making themselves apparent, and then of course I see that I only have my phone with me, because climbing in hot weather is hard enough carrying my own excess weight, let alone camera gear. 🙂 After several frustrating experiences with iPhone raw files taken during the blue hour, I actually took the Sony A7RV and the FE 35mm f/1.4 GM with me yesterday, and we also stayed out longer than usual which means that the sun set while we were on the top, and we were descending through the blue hour and into complete darkness. So, here’s the album and some individual shots. This is Biljana’s album.

I still can’t believe I got completely sharp 61MP hand-held shots in deep blue hour with stars clearly visible in the shot, and the only thing I felt I was missing was the ability to get ultra wide angle of the Zeiss 16-35mm f/4, but of course the Zeiss at f/4 would run out of light far, far before I took some of the best shots, so I would have to carry the tripod with me as well, and even if I could convince myself that it’s a good idea, fiddling with a tripod in those conditions is really impractical and possibly even dangerous, because you can barely see anything in the conditions where that camera manages to get all those colours. So, I’m considering FE 14mm f/1.8 GM, which I didn’t buy because I thought it overlaps with the Zeiss so much that one would never be used, and its strongest point is astrophotography in the mountains. Well, now that looks like more than just a fringe use case.

Communication

I was reading some American space opera stories, because I’m not dignifying that with the term SciFi. One thing seems to be a constant – “humans” in those stories are in fact a metaphor for Americans, and “aliens” are a metaphor for various non-American human nations of Earth. If you watched enough Star Trek, you’ll know what I mean. Also, how do you know that an American wrote a certain story? Because they implicitly assume that every language is basically English, but spoken with different words, that can be translated 1:1.

The only exception to that nonsense that I can remember was the “Darmok” episode of TNG, where they encounter a civilisation that keeps referencing their myths to explain current experience, for instance “Darmok and Jalad on Tanagra”, or “Shaka, when the walls fell”. Basically, it’s like a reference to “Achilles’ heel”, “opening the Pandora’s box”, or “David and Goliath”. This is actually a great example of why translating things between very different cultures while retaining the nuance of meaning is hard, and in order to understand what a Chinese would mean by “jade mind”, you need to do quite a bit of reading of their mythology and symbolism; also, good luck translating kitsune or qilin.

Basically, in order for an American to truly understand some fundamentally un-American culture, such as Chinese or Indian, they would have to do so much reading and abandoning their own mental position in order to get into another’s skin, that they would stop being Americans, because what seems to define Americans assuming that they are the top of the world and the only valid measurement of value and achievement. And we are talking about understanding merely another human culture, not something profoundly alien, like an octopus that communicates through chromatophores and tentacles, or a dolphin that probably thinks in idiom that would be as foreign to us as phrases such as “bitter anguish” or “sweet recollection” to someone who lacks a sense of taste because they feed on sunlight.

I was asked, many times, why I use sanskrit or Tibetan terms to describe certain states of consciousness or spiritual substances, and the underlying assumption is that those words can be translated to English or Croatian for that matter, and I’m just making it difficult. The thing is, if I’m not translating it, it means that there is no word or phrase of equivalent meaning in the target language, and I’m leaving it in the original because that’s how it works. The people who discover something get to name it. The Americans discovered certain elements such as Americium, Berkelium and Californium, and they got to name them. What are the names of those elements in Chinese? There aren’t any, because they were unknown to the Chinese. Every language has names for copper, tin and iron, though; guess why. So, now that the Americans discovered those elements, everybody in every other culture will use those words to reference them, because that’s how it works. That’s also why there aren’t translations for brahman, kundalini, vajra, mantra, mudra or mandala. It’s not because I’m making it hard for no reason, but for the same reason the Mongols have no word for Einsteinium. Your language has no word for vajra because no member of your culture had enough experience with it to try to conceptualise it; as Wittgenstein would say, if you don’t have a word for it, it is beyond the limits of your world.

Sometimes, in order for you to be able to understand something really alien, you need to leave your own skin and become an alien being with an alien understanding, and leave your words, cognition and feelings behind completely. Then, you will possibly formulate new words for those experiences, and thus make them something within your world, and maybe you’ll abandon words completely. Some things are, in fact, more efficient for conveying emotion or meaning; just listen to cats formulating a long whining tirade of complaint and you’ll see what I mean. So, in order to express emotion, Cat might be more suitable than English, because it expresses emotion directly rather than just map and reference it.

Explanation of real things that are beyond the experience of the audience is a serious problem, and a good example is Pliny the Younger describing the eruption of Vesuvius that buried Pompei and Herculaneum in 79 AD. He made an incredibly accurate and specific description of the eruption and the ash cloud, and yet it was historically seen as a metaphor of some kind because people in the West didn’t actually experience a pyroclastic eruption of that kind until Mt. Pinatubo, at which point they saw the ash cloud that looked like a pine tree, and said, hey, this looks exactly like Pliny the Younger’s description. Now, that type of volcanism is called a Plinian eruption, in his honour.

That’s another problem in describing things: you can be extremely accurate and specific in your description, but if your audience doesn’t have the experience you can invoke in order to form understanding, they will think you’re using metaphors or just talking about things that aren’t real, like fairies and unicorns. So that’s another very real limit of symbolic communication – it works by referencing another’s experience, and if there isn’t any to reference, you have a problem. Try describing some kind of an exotic fruit such as cherimoya or durian to someone who hasn’t seen and tasted it, and you’ll see the problem. Have them see and taste it and then give them the word for it, and now suddenly you have understanding and communication.

Intersection of paths

Within a pretty short period of time, we had three extrasolar objects of significant size (1I/ʻOumuamua, 2I/Borisov and 3I/Atlas) pass through the inner solar system. How much of a coincidence that is would depend on whether this happened before and we just didn’t have the technology to notice, but let’s assume this is indeed a new occurrence.

Some people are trying to see aliens there, but I don’t see any evidence of that. However, I think something more dangerous might be at play. I think we are passing through the Oort cloud of something massive enough to have one, and dim enough not to register on our telescopes.

Furthermore, since the comets are intersecting with the inner solar system, and not, for instance, the Kuiper belt, it means it’s coming straight at us.

Is it a black hole, or some other dark object of stellar mass, I can’t tell, and this is all a hypothesis, but still, I wanted to write it down.

Simple solutions

I had a weird IT problem that took me a long time to figure out, because it was so elusive and hard to reproduce. The NUC that used to upload the radiation data was acting up; it would just freeze for some reason. The first thing I did was reinstall Windows 11. Then I installed Windows 10. Then recently it actually got worse; it would stop refreshing data and I would come down to see it stuck at max fan speed and hot, probably 100% CPU for some reason, and not showing image on the screen nor reacting to keyboard. I concluded it’s probably fucked on a hardware level and put a HP mini PC there, with Windows 10. That didn’t fix anything, because it would stop refreshing data and I would come down to find the Radiascan software stuck. It turned out it wasn’t the software; the device itself was disconnected for some reason, and I first suspected some power saving feature, and went through everything in both Windows and UEFI; after each modification I had to leave it running to see whether it would hang, and it invariably did, in intervals from almost immediately to almost a day. As you can imagine, testing that takes a lot of time; a day per tweak, basically. Eventually I guessed the device drew too much power from the USB while charging its batteries, which overheats the USB controller or something and triggers a disconnect, so I tried putting a powered USB hub between the computer and the device, and that didn’t do anything, but I felt I was on to something, and then I remembered seeing that the USB cable connecting the device is frayed to the point where I can see the wires inside, and thought it can’t be, because it connects and reads data, right…? Right? I managed to find another mini USB cable somewhere, changed it, and it solved the problem completely.

Sometimes the solution to a complex looking problem can be remarkably simple.

Some technical stuff

I’ve been doing some infrastructure work on the servers since yesterday, essentially creating a “traffic light” for reporting online status of services, as well as the infrastructure for simultaneous graceful shutdown of servers at home, attached to the UPS.

This is what it looks like on the danijel.org site when the home copy is down due to a simulated power outage (unplugging the UPS from the grid). When I power it up, it takes 10-15min. for all the services to refresh and get back online. It’s not instantaneous, because I had to make compromises between that and wasting resources on crontab processes that run too frequently for normal daily needs. Essentially, on powerup the servers are up within half a minute, the ADSL router takes a few minutes to get online, and then every ten minutes the dynamic DNS IP is refreshed, which is the key functionality to make the local server visible on the Internet. Then it’s another five minutes for the danijel.org server to refresh the diagnostic data and report the updated status. Detection of a power outage is also not instantaneous; in case of a power loss, the UPS will wait five minutes for power to come back, and then send a broadcast. Within two minutes everything will be powered down, and then within five minutes the online server will refresh the status. Basically, it’s around 15min as well.

Do I have some particular emergency in mind? Not really. It’s just that electricity where I live is less than reliable, and every now and then there’s a power failure that used to force me to shut the servers down manually to protect the SSD drives from a potentially fatal sudden power loss during a write. Only one machine can be connected to the UPS via USB, and that one automatically shuts down, while the others are in a pickle. So, I eventually got around to configuring everything to run automatically when I sleep, and while I was at it, I wrote a monitoring system for the website. It was showing all kinds of fake outages during the testing phase – no, I wasn’t having some kind of a massive failure – but I’m happy with how it runs now so I’ll consider it done. The monitoring system is partially for me when I’m not home, so I can see that the power is down, and partially to let you know if I’m having a power outage that inhibits communication.

The danijel.homeip.net website is a copy of the main site that’s being updated hourly. It’s designed so that I can stop the hourly updates in an emergency and it instantly becomes the main website, where both I and the forum members can post. Essentially, it’s a BBS hosted at my home with a purpose of maintaining communications in case the main site dies. Since I can’t imagine many scenarios where the main site dies and the ddns service keeps working, it’s probably a silly idea, but I like having backups to the point where my backups have backups.

Also, I am under all sorts of pressure which makes it impossible for me to do anything really sophisticated, so I might at least keep my UNIX/coding skills sharp. 🙂
