Somewhat but not exactly. You can only go north or south until you hit the poles, but you can travel forever at angle zero starting from the center point. I guess you could call towards the center point "North" and away from it "south", so the galactic center is the North Pole but there is no equivalent South Pole. But angle zero is more analogous to the prime meridian - it's a line that goes north-south but there are an infinite number of such lines, and we could have called any of them zero.

I think it would not have a shape, or would rather be a zero dimensional point. For it to be any shape, it would have to have features, but you've already defined this as the fundamentally smallest 'thing' so it can't have any features smaller than itself. But you could also probably convince me that it's a sphere. I'm not sure if mathematicians consider a sphere of infinitesimal radius to still be a sphere or not, but treating it as infinitesimal kinda makes sense to me even if it's actually finitely small (the Planck length?)

A more interesting question to me is, assuming positions in space are discrete, which I'm not sure follows from saying there's a smallest possible object, how are those 'voxels' arranged? I don't think that's necessarily equivalent to asking what the shape of the smallest object would be. Pixels on a screen are in a rectangular grid, but the actual elements are circles in some types of screens.

There are a number of shapes besides cubes that can fill 3D space, but do the voxels even have to all be the same shape? Are we even looking for a 3D tiling, or could it be 4D in spacetime, or even higher dimension if it turns out the universe has more than 4 dimensions? Does it have to tile at all, or could it be entirely irregular while still being discrete? Is there any conceivable experiment that could prove any of these things, or is it unknowable?

The post says I'm the boss, so as a human I'm going to pick my own home galaxy as the reference. Alien species would have their own coordinate systems but it's not that hard to convert between them, or to specify which reference you're using. We'll already be converting between planetary/system/galactic/intergalactic coordinate systems all the time so it's not much harder to account for a few more.

Within the Milky Way a polar (cylindrical) coordinate system makes more sense than Cartesian - there's an axis of rotation to define the center and 'up/down' directions. Zero degrees is arbitrary but a line from the galactic center to Sol, projected onto the galactic plane, would be an obvious choice as a sort of galactic prime meridian. 'North' and 'south' don't really map to a roughly disc shaped galaxy - you'd use distance from center, angle, and 'elevation'.

On an intergalactic scale, the center of our own galaxy is probably still the obvious choice for a center point. We could use the same axis and meridian - I don't think the rotation of our galaxy matters on any human timescale, and on the time scales where it does matter, everything is moving relative to each other so coordinates already aren't 'fixed'. I'd use a spherical coordinate system instead of cylindrical for intergalactic coordinates, since things are not roughly in a plane anymore.

If you want a fixed coordinate you'd have to include a time dimension, and as the zero point for time I propose the Unix epoch. Not because it makes any sense but because it's extremely funny to imagine computer systems in the year 10000 still relying on that legacy decision. Though special relativity makes 'point in time' rather complex as well - I don't know enough to know what you'd actually need to make that work.

Of course we already have such coordinate systems for astronomy if you want to know the 'real' answer, one of them is pretty close to what I just came up with: https://en.wikipedia.org/wiki/Astronomical_coordinate_systems

During the Reddit API stuff, same as most of the folks here. I tried kbin first but lack of an API or mobile app at the time pushed me to Lemmy instead.

I eventually caved and started using the official Reddit app, but I still check here as well - less content but I like the vibes here. Reddit hasn't been the same since the protests - might just be bias but I feel like 'brain drain' was real and quality discussions over there are a little less frequent than before.

My first VPS was for a Minecraft server so I named it cobblestone. I've kept using Minecraft related names for all my machines since then, and I try to pick ones that are at least vaguely related to the function or appearance of the machine. For example my cluster has brute for the master and piglin01-piglin04 for the workers, but those are the only ones I've numbered.

The exception is my two Klipper RPi's, one is octopi since that's what it originally ran, and the other is named after the model of the printer. For some reason I never named my printers.

I probably wouldn't use a naming scheme like this for production servers though - I'd either go with functional hostnames or something like the periodic table which you can pick from arbitrarily. My home servers and clients aren't cattle though, so I like having a little personality to the names there.

SponsorBlock is essential now. I switched from iPad to an Android tablet largely so I could use YouTube ReVanced. And on Android TV there's SmartTube Next.

I get that creators gotta eat, but I pay for YouTube Premium already. If they would stop accepting sponsorships from scam companies I might even stop blocking those.

One of the big problems with JIRA is it's extremely configurable, so your experience depends entirely on how your admins have set it up. If your company is the type to micromanage, JIRA gives them a lot of tools to do that, which I think is why it gets so much hate from devs. I find it tolerable in my current job but it's definitely designed for managers and not for developers.

Carbon Black. As a software developer, running unknown/untrusted binaries is kind of a big part of my job. We also had a MITM SSL-intercepting proxy which made my life miserable, especially when dealing with Docker containers. I actually ended up patching Docker to automatically inject the certificates and proxy environment variables.

On the plus side I learned a lot about certificate errors which has made me the go-to guy for any SSL issues in my current job.

+1 to this! I bought the same chair from them a couple years ago, and as a remote worker it's been worth every cent. Oddly enough I had the Leap v1 as a previous job and hated it, but the v2 has been great for me. I found the armrests a bit uncomfortable but some cheap memory foam covers solved that.
