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. The Scale of Climate Change youtu.be/Rmk6vAQN2p4

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 www.youtube.com/watch?v=9S0L...

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

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"

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.

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

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.

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.

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?

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'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) #mcdev #minecraft

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. #mcdev #minecraft

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. Open with F3+F #mcdev

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".

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. Check it out on modrinth: modrinth.com/datapack/lav... #mcdev

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.

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!

I've just released an update to my #minecraft datapack map: - You can now directly select datapacks from @modrinth.com. - Added URL parameters for the settings and datapacks. For example, you can directly open a Terralith map using: map.jacobsjo.eu?datapacks=mo... #mcdev #DatapackShowcase

A menu of the datapack map. The menu was opened by clicking a "plus" button at the top. The menu consists of the following entries: "Open Pack or Mod", "Open Folder", "Open from Modrinth", a subheader: "Built-in Datapacks" with entry "Winter Drop", a subheader: "Recently used" with entry "Terralith". The rest of the menu is cut off.

A modal menu titled "Open from Modrinth". A x button is on the top right. Below the title is a search bar and 2 settings "include mods" and "ignore minecraft version". Below that is a list of datapacks with an image, title, description.

Have you ever wanted to see a map of how a specific #minecraft seed generates? But you are playing with datapacks that modify worldgen? I've got an online solution for you: map.jacobsjo.eu (Works with some mods too, but not with all) #mcdev #DatapackShowcase

A map showing Minecraft biomes by color. The map shows multiple continents surrounded by water. The water-color also differs based on the specific ocean biome. Shading indicates terrain relief. On one continent a symbol indicates the spawn point.
