essentially a terminal modal editor (like vim), but instead of specifying the action to perform then what to perform the action on (like “yank 3 lines”), in helix you select first, then perform actions on the selection (like “these 3 lines, i want them yanked”). it’s slightly better (according to others) because you get to see what you’re going to change in the file so you don’t accidentally delete 5 lines instead of deleting 4.

on top of that many features are builtin, like tree-sitter and lsp support, so you don’t have to spend 5 hours looking for cool plugins and configuring everything to get started (my config file is only 50 lines of toml).

the downside is that there isn’t support for plugins (yet), but there’s already things like a file picker, more than 100 themes etc.

is there not a single other person who uses helix?

for me its 1/10, i can see the orange but can barely tell what it is. unless i circled every orange dot there was no way i was gonna figure it out. i thought it was a diagram

what if a red giant star was placed in the pacific ocean? would y’all like to find out?

there’s only 18 cigarettes though

yeah, he’s actively promoting climate change. nothing wrong i see

smash hit

that is true. the mechanism shows us that they definitely had some mechanism making culture going on. my point is that, despite how bizzare and sophisticated it sounds, this sort of thing was 100% doable for their level of tech, and that it is us who have misunderstood history. the hype surrounding it, making it sound like a supernatural creation and way more intelligent than it actually is, is bs.

anthoer thing is that this machine clearly wasn’t the first draft. not only do we have those mentions of “spheres”, but there aren’t that many mistakes we see in the construction of the mechanism (apart from the dovetail joint). clearly the layout of the gears was planned beforehand, or they did trial-and-error with the gears on another version of the mechanism.

if you will it hard enough it can even play crysis.

seriously, most of the hype for this thingy comes from some random documentary directors who thought the ancient greeks were as intelligent as monkeys and such. anyone who says this is an alien invention is basically insulting any intelligent life who has come far enough to go interstellar

to clarify, this machine is way less impressive than what a lot of media claim it is. the greeks had hundreds of years of stargazing and records to figure out a model of the cosmos, and this is basically their whole model in a mechanism. unfortunately, at the time this thing was made, their model was pretty far off and they couldn’t come up with a better one due to philosophical reasons (the earth is the center! the orbits of the planets must be some sort of perfect circles!).

anyway, this thing is somewhat impressive technically, but is really bad in terms of engineering:

• the teeth of the gears are triangular. there is a part of the mechanism that is super elaborate and calculates very precisely the motion of the moon and how it slows down and speeds up occasionally, but because of the triangular teeth, whether or not this actually worked is debatable.
• the mechanism used crown gears, which are pretty bad because they don’t mesh well with the regular gears.
• some of the gears are put under a lot of strain, particularly gear d1, a small gear that sits at the end of the gear chain b2 -> c1 -> c2 -> d1 (which gets faster and faster)
• the mechanism has a lot of spacers soldered into place and rivets that were hammered in, making disassembly rather difficult. however some of the components are fastened in by pins.
• the main gear b1 (the large one with the cross spokes you see in the picture) was built in a very weird way: the gear itself is a ring, and the spokes are added on later, connected to the ring with dovetail joints which aren’t the easiest thing to make when your level of tech is a file and some sandpaper. in fact, whoever made the mechanism probably screwed up one of the joints and had to rivet in an extra metal plate so it wouldn’t fall off.
• the gear trains for the moon is built in a very weird way: first the main axis b drives 2 separate gear trains that pass through the main plate, only for one gear train to drive a turntable (e3 and e4) and the other to drive a shaft (e2 and e5) that goes through the center of the turntable. e5 will then drive a mechanism on the turntable which has an output shaft… that once again goes through the center of the turntable and the e2-e5 shaft (e1 and e6). then finally e1 drives b3, which drives a shaft that goes right through the center of the b axis. so now, you have 3 pairs of gears on the e axis whose shafts all go through each other like some matryoshka doll, as well as a hole right through the b axis to display the position of the moon.
• the metonic and saros spirals on the back need resetting once in a while, because the pointers move in spirals and can’t automatically reset once they hit the end.

we knew that the greeks had a model of the cosmos before we discovered this (i think). we also knew, from greek records, that there were people discussing about “spheres” that tracked the positions of the planets, sun and moon as they moved through the sky. the main thing this mechanism shows is that the ancient greeks possibly pioneered complex gear mechanisms, and the knowledge was then passed on and on and went through times like the islamic golden age before coming back to europe in the form of clockwork and watchmaking.

the ancient greeks came up with their own model to track and predict

• the positions of the planets
• the position of the sun
• the position and phase of the moon
• solar and lunar eclipses

this machine is basically their mathematical models summarized into mechanical form

i was here for systemd round 2

wasn’t 19 june like 2 days ago? what happened?

yeah that makes sense. i was thinking maybe youtube had servers to decide what chunks clients would get, maybe by looking at whether or not they are premium users first. but anyway youtube still needs a way to differentiate between ad chunks and video chunks, otherwise we would just be able to skip 10 seconds through all the ads. surely that can be exploited somehow.

does this mean stuff like yt-dlp will download videos with ads in thrm as well?

huh, so i’m one of the first lemm.ee users (my cake day seems to be tomorrow, might be wrong because timezone stuff)

i remember back then wanting to join an instance but hearing lemmy.ml was overloaded and i should join lemmy.world instead. then over in the comments i saw you say that you made an instance and i decided to just join it. in hindsight i don’t know why i expected some instance hosted by some random guy who made a short comment to last longer than 2 weeks but i’m super glad it did (it was extra stable too). well done hosting your instance and helping us all out.

sorry, did middle schoolers get taught the earth spins twice a day? 3 times? 17 times? or maybe they get taught that the time taken for it to spin once is actually called the sidereal day and not the synodic day?

if you want to measure how fast things spin, use angular velocity. your car engine goes at several thousand rpm, not several thousand kilometers per hour. if you were standing at the poles, you would have zero linear velocity. does this mean the earth doesn’t spin?

ok maybe you were talking about the time the earth takes to go around the sun. yes that takes a year.

funnily enough this is one of the main reasons why flat earthers cant comprehend a globe
