> Fun fact: Jansson illustrated The Hobbit and drew Gollum as a giant. Tolkien realized he never described the size of Gollum and made adjustments to later editions.
For those curious like me, here are some low-res images:
This sounds like what RNode devices for Reticulum networks appear to be able to do. (I haven't tried it for myself yet.)
> RNodes can be made in many different configurations, and can use many different radio bands, but they will generally operate in the 433 MHz, 868 MHz, 915 MHZ and 2.4 GHz bands. They will usually offer configurable on-air data speeds between just a few hundred bits per second, up to a couple of megabits per second.

> While speeds are lower than WiFi, typical communication ranges are many times higher. Several kilometers can be acheived with usable bitrates, even in urban areas, and over 100 kilometers can be achieved in line-of-sight conditions.
> Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. Reticulum can continue to operate even in adverse conditions with very high latency and extremely low bandwidth.
> Sure, in some cases, when the network has fewer announces to deal with, the 2% limit has less effect, the best way Reticulum can deal with this is with a network made out of more specialized node types connecting the lower speed links (http://reticulum.network/manual/interfaces.html#interfaces-m...)
I see. So it seems that optimizing a complex network can be a little more hands-on, not completely automatic (which would be a bit too much to ask, thinking about it). I guess my hypothetical path via outer space would have a "boundary" mode node somewhere on the way, although I am still fuzzy on how exactly this would affect things.
And your point about the announce queue with saturated 2% bandwidth is clear.
Thanks so far! This makes me want to read the rest of the manual and possibly start tinkering with Reticulum myself at some point.
That does make a lot of sense, at least in terms of latency: I imagine that when a one-hop announce comes back from outer space, the faster multi-hop path across town will have already been established.
For bandwidth, however, I don't see it yet. If all relevant nodes are idle at the time an announce comes in (so the 2% limit doesn't come into effect), a low-bandwith route might be established before one with a much higher bandwidth, no? (Prioritising latency over bandwidth can be the right thing to do, of course, depending on what the network is used for. But it might not.)
Thanks! I had thought it would make sense to post this chapter of the Reticulum manual separately, as the other post is about Nomad in particular. But since my post here didn't get traction, I repeated my question over there now.
> Once an announce has reached a node in the network, any other node in direct contact with that node will be able to reach the destination the announce originated from, simply by sending a packet addressed to that destination. Any node with knowledge of the announce will be able to direct the packet towards the destination by looking up the next node with the shortest amount of hops to the destination.
To me that chapter ("Understanding Reticulum") was a very pleasant read a few weeks ago, and inspiring too. I would love to get some HN expert opinions on it, especially about routing, so I posted it separately:
> Once an announce has reached a node in the network, any other node in direct contact with that node will be able to reach the destination the announce originated from, simply by sending a packet addressed to that destination. Any node with knowledge of the announce will be able to direct the packet towards the destination by looking up the next node with the shortest amount of hops to the destination.
Do I understand correctly that routing always priorities the path with the fewest hops? With Reticulum being "medium agnostic", I imagine this would not always be fastest in terms of ping or throughput: A destination might be reachable via a single hop via Mars, even though three hops across town would be faster.
I fully support the recommendation of Le Guin's short stories! Too bad they are easily forgotten over her novels. (I guess a novel, as a product, is easier to review and to advertise?)
My favourite collection is "The Birthday of the World", especially the stories "Solitude" and "Paradises Lost". (Maybe skip "Old Music and the Slave Women". It builds on other books and is incomprehensible without them; or at least it was to me.)
Back then I stopped using sc-im because it could not import/export XLSX, if I remember correctly. Apparently it can today!
vim-table-mode always felt a little fragile and I don't want to be bound to vim anymore. That said, it still feels like a small miracle to me to have functional spreadsheet formulas inside markdown documents – calculation and typesetting all in one place.
I didn't know about DMXIS and tried to look it up, and it seems that there is a software and a hardware component (the latter not being produced anymore), see here:
I don't know about the software, but as for a DIY hardware solution, you can just connect a USB-DMX interface (like the Enttec DMX USB Pro) and a USB-MIDI device to a laptop and "just" have to code something to translate MIDI input to DMX output. Or use an Arduino, an RS-485 module and a few other components, that's what I once did.

> As an untrained but interested bystander/hobbyist, the scores engraved by Lilypond are orders of magnitude better than those produced by the mainstream WYSIWYG editors, in the same "I deeply care about typography" sort of way that you get from documents produced with TeX but not Word or Google Docs.
This deep care is documented in the "Essay on automated music engraving" in the Lilypond docs:
The title is indeed ambiguous. It could just as well refer to sound-coding systems/languages like Sonic Pi, or to what you imagined. (Which would be an oddly specific kind of music, but cool! The operation of a compiler turned into music, somehow?)
That said, I am not disappointed. But then I am also the one who posted this link in the first place. I started using Lilypond last year for transcribing the melody voices from complex sheet music and automatically transposing them into different keys when needed (which is immensely useful). Just recently I discovered that it can also generate MIDI output, so in addition to having a convenient tool to get beautiful sheet music in whatever key I need, I can now easily have my computer play the melodies and memorise them by listening (which for me, on my current instrument, is much easier than playing from notes directly).
I'm a freelance performance and theatre artist. This means (in my case) that I stage/create performative works of my own, perform in other people's pieces and sometimes build special effects using electronics and programming.
I used to study physics before I got serious about theatre, and my dad is a programmer. I think he introduced me to HN at some point a few years ago, and today I am using it daily to indulge my curiosity, laziness and procrastination. (;
This is an awesome thread to read, thanks for posting the question!
Ursula K. Le Guin, "Solitude", from the collection "The Birthday of the World". Speculative story about a society whose adults spent the majority of their lives alone. Told from a female perspective. One of my favourites, to say the least.
This is pretty similar to what is described in Stanisław Lem's "The New Cosmogony" (a work of fiction, included in the book "A Perfect Vacuum"). Only there the terrarium-like isolation of intelligent species is a self-imposed restriction: The earliest civilisations of the cosmos engineered the laws of physics that way.
Sure! I'm assuming if we have the means to fake the one turbulence, we can also cancel the other. Or the arrow is just not moving, thus no "natural" turbulance to cancel.
I'm not saying that air turbulence wasn't a very strong indicator for motion! And I am not sure the technology to fake them completely does exist. But I don't see why it shouldn't be possible, maybe with a very elaborate set of fans, air ducts and loudspeakers.
