This exploit was found with the help of eva and @katietheqt, you should go check them out!

I was talking to a friend, and we got onto the topic of Minecraft player heads. Skulls are loaded from Mojang servers but this link itself is stored in the NBT of the skull, so I wondered if there was a way to tamper with this. Turns out there is!

Minecraft skin loading

When your client loads a skull or a player, it needs to load it's skin. The skin is stored in the profile, which contains properties like textures. Here's an example of properties from a minecraft:profile item component on a player skull:

Spawning in items using map pings in Don't Starve Together

Don't Starve Together

Don't Starve Together (DST) is small survival game I've played for quite some time now. It's something I'd pick up every year or two and play with a few friends or on a public multiplayer server. According to my Steam stats I've poured over 1000 hours into this game, which is honestly more than I had expected.

DST modding

Something I've not messed around with too much is the modding the game has. It's all done in Lua (yuck!), but you can make some pretty cool stuff with it. A mod I really liked is Epic Healthbar. It shows the health of the bosses and mobs you're fighting, but in a really nice way with more information such as the phase of the boss.

Tricks

This is my small personal collection of a bunch of random tricks that I discovered and decided to write down.

Get a seeded/persistent random-ish float/double from a UUID

This is a quick and simple way to get a float/double value between 0 and 1. The number will be almost perfectly random, as long as the UUIDs are random, but won't change for the player who the UUID belongs to. This is great for picking e.g. a color for your specific player.
