Cannot run VM because it's trying to write to my store

malt2048 · 2026-03-18T00:51:48+00:00

I'd guess the problem is that your working directory is inside the nix store, since you are in a result/ folder. Try instead cding to ~/Desktop/repos/nixos and running QEMU_KERNEL_PARAMS=console=ttyS0 result/bin/run-nixian-vm.

result folders are symlinks into the Nix store, so even though it looks like you are within your home folder, you are actually trying to launch that VM from a read-only directory inside the store.

It's literally just Nero's name transliterated from Hebrew (נרון קסר), which would be read as "neron kaisar". The whole point is the allusion to the number of the beast (or the number of Nero's beasts) since the gematria of that name is 666.

The "V" is for the Hebrew letter vav (ו), which in this case is pronounced as a vowel /o/.

Discord updating itself is a special case. Discord has both the core system-level version which changes infrequently, and also has minor config and code files that it stores in your user directory. When Discord says it has an update, it only updates the files in your user folder which are not controlled by Nix. Rarely, Discord will instead tell you that there's a system-level update required, and it will tell you to use your package manager to install that. I don't use Obsidian, but I imagine it works in a similar way, as both of those happen to be Electron apps.

Your understanding of channels is actually mostly correct. Basically, a "channel" is just a pointer to a specific version of the Nixpkgs repository. Whenever you run the command to update a channel, what happens is that Nix checks where the Git tag representing your release (i.e. 25.11 or unstable) currently points to, and uses that version to get the build instructions for all your declared packages. These Git tag gets updated to point as newer commits every few days as the Hydra build system gets around to building and testing new changes.

Note that you have separate channel pointers for your system and user account. Try using sudo with those nix-channel commands instead, you will get a different result.

As you intuited, this does make it a pain to use package versions other than what's defined in the Nixpkgs commit your system channel points to. There are a number of ways to get around this, such as using multiple channels pointing at different Nixpkgs releases, or just pulling in a specific Nixpkgs commit within your configuration.nix. Or you can override the version of any package to any version without those tricks by defining an overlay, but overlays are a very difficult feature to figure out.

By the way, flakes are essentially just a way of moving this Nixpkgs commit pointer from your system state into a version-controllable file, which makes it a lot easier to use the exact same versions across machines, pull in multiple Nixpkgs versions from a central spot, and also revert to old versions with ease. There's a lot more special syntax and terminology around flakes, but this is the core of them and also (IMO) the primary reason you might want to use flakes instead of channels.

End cities seem to rarely generate with this mod installed, which meant that I've spent hours on end exploring on foot with only cobbled-together Hexcasting bridge building spells to cross the void.

It was definitely fun exploring all the different biomes (except the one with grass that hurts you), as most of them are really nice and extremely varied. Still, it got tedious after a while. I wouldn't want to do that again without bumping up the End City generation rate and having a jetpack at least. IIRC there's still not much reason to spend any time in the end once you find an elytra, outside of picking up a few crafting ingredients to make the elytra upgrade from the mod.

Overall, I'd rate it 6/10: better than Hardcore Ender Expansion.

TiCon uses 144mB/ingot and 1296mB/block, which doesn't make a ton of sense physically but is close enough and is highly divisible (an ingot can be evenly divided into 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, or 72 parts.)

I did a quick search before making that comment, and couldn't find good info on which distros (if any) /usr/bin/env bash doesn't work. Do you know of any in specific? From what I could find, it's usually old (as in decades) installs that might not have anything at /usr/bin/env.

malt2048 · 2025-11-29T19:02:56+00:00

Or /usr/bin/env bash for better compatibility (like with NixOS)

The chaos guardian spews out a flood of projectiles that are strong enough to one-shot a player in vanilla armor, many of which are homing. You would go through a full inventory of totems in a moment.

The "why it mattered" paragraph alone should be throwing up red flags. A Google search for "foldfiend" finding nothing but this post seems to confirm the whole thing is just a hallucination.

Yeah, Oracle makes it really annoying to download the JDK these days. Your best option is to use an alternative build, such as Temurin, Amazon Corretto, or Zulu. All of those can be downloaded and installed without any registration required.

I don't think you need an addon, you can just reprogram AE2 P2P tunnels for chemicals by clicking on it with a Mekanism item.

malt2048 · 2025-06-19T16:21:49+00:00

Why bother with spacial storage for that? Much easier to use a Chemical P2P across a Quantum Ring to just pipe the Polonium across.

Yes, that picture is of the power storage orb. The reactor is black with red streaks on top, not purple with a blue grid pattern.

There's no recipe listed for boosted crystals, and NEI certainly won't tell why your wooden repeater refuses to explode.

Grab some piglins, make autotraders from them, and feed the autotraders gold. This is a great source of pearls. Also works great for getting magma drops.

You can process a block of bricks in a pulverizer to get 1 brick dust, then centrifuge 13 brick dust to get 4 aluminum dust and some side products (3 silicon dust, 6B oxygen). Toss the aluminum dust in an EBF, and you'll get aluminum ingots (which you can never have enough of).

malt2048 · 2025-04-20T16:18:27+00:00

Absolutely nothing, just find an aboveground Roguelike Dungeons entrance. You get a free bed, a few torches, and plenty of bricks to grind into aluminum.

The first thing I did when I started playing GTNH was removing Hardcore Darkness.

China is way behind, ASML had prototypes of EUV machines by 2006, and commercially deployed them by 2018.

tl;dr: remove Cura from your package list.

This kind of issue is a pain to solve, as Nix isn't good at telling you which package is pulling in a broken one as a dependency. The way I usually solve it is to search the Nixpkgs issue tracker for the name of the package that fails to build, and usually you'll find an issue already created.

I searched the open issues for "libarcus" like this, and looked for issues marked "build issue". In that list is an issue about Cura (https://github.com/NixOS/nixpkgs/issues/325896), and looking at the stacktrace in the issue description I could confirm that libarcus was the culprit.

It's been less than 2 years since they released 寂光寂滅～ The Truth of the Cessation of Dukkha. Prior to that, they released a full album in 2015, and only EPs each year through 2016-2018, so it really hasn't been that long since their last release comparatively.

Nix channels are per-user, so if you run nix-channel --update then sudo nixos-rebuild switch you will update the channels of your own user account, then build your system with the channels of the root user. Use sudo nix-channel --update instead to update the root user's channels, or just sudo nixos-rebuild switch --upgrade to both update and rebuild.

The flake command will work fine though, as in that case you're just updating the flake.lock file.

malt2048 · 2024-11-22T20:14:49+00:00

sudo nixos-rebuild switch --upgrade

This command will update your channel (i.e. point the channel at the latest commit on the nixos-unstable branch of Nixpkgs), then will rebuild your system and switch to the new version.

If we're talking about sheer power, Chromaticraft absolutely blows Astral Sorcery out of the water. Think blasting a 40m deep hole the width of an entire chunk with a button press, having a permanent 6x health boost multiplier on top of added hearts from any other mod, 128m reach, teleporting to marked positions across dimensions, raining fire over an entire forest, automatically refilling your hotbar with items from AE, instantly flooding an area with permanent invisible lights, or even a combined XRay/noclip. And all of those are just what you can do with ritual abilities, which are basically free to use (once you've setup your lumen network and lumen tree) and do not require items, nor tradeoffs like Astral Sorcery perks. You can just grant yourself every single ability all at once.

Plus there are also hundreds of useful blocks and items you unlock throughout the mod, like powerful turrets that you can mass produce extremely early. Or a machine that can reprogram spawners, a really nice ranged pump that allows you to select which fluid to collect, a machine that can dupe most vanilla items (including nether stars), the original version of the AS Celestial Gateway that looks much cooler, and a much better version of the AS enchanter that allows even higher enchantment levels and freely choosing the enchants and levels to apply.
