#or semaphore signal

[heavyweaponz]

Sona drawings, cuz, i Felt like drawing Him i forgot his wings on both drawings ignore That and selfship thingy below um

yeah thats all

[gowns]

i also run into a funny thing, dating in LA, where people are either like, "oh yeah i also love watching movies, i can't wait to see [upcoming slop]," or they're like "oh, that theater you like is actually sub-par, its programming is too obvious, it's not showing enough underground films." it's either high or low... where is my mid queen

The line to Skegness played host to these archaic 'tumbler' signals, also known as 'somersault' signals, long after they had been abolished elsewhere on the network.

They survived until the mid 1990s, astonishingly. Our photographer here, Neville Stead, has composed a rural looking scene, with wooden fencing, trees and an older DMU train.

Another poll???

Oh yeah, you know it.

Again, this question was revealed to me in a dream, and so I pass it onto you to answer.

THIS is the semaphore flag system, it is used to communicate over long distances, most usually at sea:

And THIS is the international code of signals, again, it is primordially used to communicate between ships at sea, the main difference being that these flags are hoisted somewhere in the ship, forming a sentence, and they're aren't waved around like the other one:

anything that has to do with memorizarion is the actual villain in my story

Please - explain the "gnu terry pratchett" tag you use?

Sure! It's from his Discworld novels (Going Postal). It's the in-universe version of "no one's truly dead as long as their name is still spoken".

The Discworld has a semaphore communications system and the operators use lettered prefix codes on certain messages to indicate whether they're for admin/system use in the semaphore towers rather than for delivery.

Adding GNU to a message means it should get passed on to the next tower in the line (G), processed without logging (N), then turned around at the end of the line and sent back the other way (U). So once started, the message is always kept moving through the air, tower to tower - always remembered, kept alive. The signallers, who've somewhat mythologised aspects of their jobs, start doing GNU for the names of their fallen comrades.

GNU Terry Pratchett. An in-joke and an in memoriam, cuz we miss and remember him.

Electrical Telegraph

The Electrical Telegraph was invented in 1837 by William Fothergill Cook (1806-1879) and Charles Wheatstone (1802-1875) in England with parallel innovations being made by Samuel Morse (1791-1872) in the United States. The telegraph, once wires and undersea cables had connected countries and continents, transformed communications so that messages could be sent and received anywhere in just minutes.

Telegraph Pioneers

The idea of sending signals from one distant place to another has been in use since antiquity, notably with towers using fire beacons. Ships have long used a system of flags (semaphore) to communicate beyond shouting distance. These methods, though, were limited to only very important communications, for more mundane messages people had to use horse-riding messengers that could take several days or even weeks to reach their intended recipient.

The Italian Alexander Volta (1745-1827) invented the electric battery in 1800, necessary for a telegraph machine to be operated anywhere. Then the Danish physicist Hans Christian Ørsted (1777-1851) created the first electromagnet in 1825. Ørsted's discovery that an electrical current flowing in a conductor can create a magnetic field – which he noted when observing the effect on a magnetic compass on his desk – was crucial to the telegraph machine since this was the answer to the problem of how to make electrical impulses visible in the form of a moving needle. The French physicist André-Marie Ampère (1775-1836) worked to create a theory that explained the relationship between an electrical current and magnetism. The first electric motor was developed by the Englishman Michael Faraday (1791-1867) in 1821. With all of these scientific discoveries put together, inventors now had the theoretical means to send electrical impulses through a wire and then see the effect at the other end. The trick was just how to create a working machine capable of sending and receiving these impulses over long distances and a code by which such impulses could be transformed into words.

I love discussions of Ed and Stede switching out the stoplight system for signal flags. Edward "Offensive Semaphore" Teach would be incredibly extra about this.

Stede: Color, sweetheart?
