The Scale of Climate Change
The Scale of Climate Change YouTube video by Gneiss Name

I wanted to give some perspectives on climate change and the relative values for CO2 and Carbon in general. So I scaled them all in Minecraft.

Intro to Snowcapped | Smithed Summit Panel
Intro to Snowcapped | Smithed Summit Panel YouTube video by jacobsjo

About a year ago, I held a panel at @smithed.net Summit about my Minecraft biome-layout editor Snowcapped, including a step-by-step guide on how to use it. I've finally uploaded an edited version of that panel. #mcdev

A screenshot from a Minecraft desert but with a red sky.

The chat is open and shows 2 lines:
minecraft:visual/sky_color: "#6eb1ff"
Environment attribute minecraft:visual/sky_color set

In the chat input box the following is being written:
/environmentattribute set minecraft:visual/cloud_color "#00FF00"

I've just released version 1.4.0 of my worldgen-devtools mod that features a /environmentattribute command that lets you query and set overrides for the new environment attributes introduced in Minecraft 1.21.11. Get it here: modrinth.com/mod/worldgen... #mcdev

The EU has let US tech giants run riot. Diluting our data law will only entrench their power | Johnny Ryan and Georg Riekeles The GDPR is Europe’s defence against digital oligarchy and child harm. Deregulation plans are misguided, say Johnny Ryan and Georg Riekeles

🗞️ "In this moment of crisis, #Europe should not cripple its best weapon against #US tech dominance, but enforce its laws, defend its sovereignty, create the space for innovation, and prove that democracy can tame Silicon Valley."

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.

The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

A screenshot of a Minecraft world that looks like a cake. It consists of 4 layers. Each layer has frosting on the top and brown cake below. There are a lot of candles on the cake. In the foreground, there is a pink "river".
The sky is pink with the normal white Minecraft clouds.

Today is the 5th anniversary of #Minecraft data pack #worldgen! Snapshot 20w28a added the ability to define custom biomes, structures, etc. through data packs. It's hard to overstate the impact this change had on modded worldgen. Very proud of what our community has made with it so far! #mcdev

I've tried to fix that one multiple times over the years. Finally had the right idea of how to do it. It was surprisingly simple.

A screenshot of a section of a website, where the text is describing what the text itself should say. For example, 'Clear Message: Show a short line like “DxWnd is safe, open-source, and malware-free.”' instead of the actual example text.

I almost fell for a scam site today, pretending to be the homepage of an OSS project that I was looking for.
It looked convincing until I scrolled to read more text. LLM slop is getting scary good at "looks good at a glance".
I don't even know _how_ they managed this. Feeding LLM into LLM somehow?

I'm disgusted by the concept of generative AI tooling for Minecraft mods. This isn't the first one and it sure as hell won't be the last, but it made my blood boil regardless. (1/5)

The dialog generator now has a visual preview, closely matching vanilla! #mcdev #datapacks

The update also adds dry grass to the nether wastes, fallen crimson trees, and rare soul lanterns to ghost trees. It also fixes a bug with pillars cutting off caves.

The update is out now. You can get it from

Turns out the firefly particles make very good nether ambient particles too. In the Lavaflow 1.21.5 update, I've added them to the ghost forest.

Sort of. Not all mods work (only those that do their worldgen like a datapack work), but when only using those it is possible to add multiple at the same time. You'll have to add each one manually though.

A Minecraft screenshot from inside a old growth pine taiga, with a river in the background. A number of markers of different colors are placed on screen, consisting of a cube and text above. The closest markers reads "minecraft:patch_brown_mushroom", "minecraft:patch_taiga_grass" (2 markers), and "minecraft:forest_rock".

Trying to figure out ancient debris distribution in Lavaflow, I wished to have a visual marker for each placement position. So today I've implemented a debug renderer for feature locations into my Worldgen Devtools mod.

Just released that in version 1.3.0 for mc 1.21.3 and .4.

Probably. I've also made Striders immune to fall damage so you can safely ride them down the lavafalls.

I've also though about adding some kind of "strider staples" structure to make it easier to get a strider to ride over the ocean.

Looking down at a nether fortress over a large lava ocean. In the foreground the end of a lava river is seen between crimson forest. The river leads towards what appears to be a lavafall, though that is only visible from the back.

A lava river flowing through a soul sand valley. The valley is more flat the the typical nether. A large ruined portal is placed on the right shore. Behind the portal is a mysterious forest formed by trees with bone stems, white leaves, and glowstone.

A elevated view of a lava river flowing though a valley with basalt deltas and soul sand valley biomes. Above the valley is a series of floating terrain stips that can be used as walkways. A tower in the foreground provides a connection between the valley floor and these walkways.

In the background a bridge of a fortress can be seen reaching over the river.

Finally published a first Alpha of "Lavaflow", a #Minecraft worldgen #datapack / mod that completely overhauls the Nether. It includes lava rivers on 2 heights with lavafalls between them, proper valleys, oceans and more.

I've also updated my datapack map to reflect this change if 1.21.4 is selected. In the process I also added the y position of the structure start to the markers.

For custom sky islands dimensions the only way around this issue until now was to change the biome layout to have a different biome at y=0. This is not possible to do with the vanilla end though.

A change I would like to highlight from #Minecraft 1.21.4 is a bug-fix: MC-272062 - "Dimension padding doesn't affect the start piece." This fix makes it possible for data packs to add structures to the end without them ending up in in the void at y=0. #mcdev

I'm really glad I'm just developing a website for making zip files for a block game. Takes away a lot of pressure when rolling out major rewrites!

Well its worth exploring (once there are actually packs worth including), but downloading files (that are potentially large; resource-packs for localization) directly from an API initiated by just opening my map with URL parameters just sounds like a bad idea. Caching would also be a problem.

Would also need to use the /download api route as a proxy since I otherwise couldn't be sure the external download sites set access-control-allow-origin: *
Not sure that's a good idea though.

I've thought about it. But not worth doing as long as there are exactly 0 worldgen datapacks on smithed.

- Since referencing from disk doesn't work in Firefox, selected folders aren't added to the "recently used" list there. The reload button also doesn't really work. Thus for datapack development, I recommend using a different browser.

(To be clear, those last 2 point have not changed in this update)

- This also means that the recently used menu now works in Firefox
- Folder datapacks continue to be referenced from disk. Since folders are mostly used during development this means that updating the datapack is automatically reflected in the map: In dev mode just press the reload button.
