Find your home in Minecraft: here’s how to see your real-life city in incredible detail

Minecraft has evolved into a platform that allows users to create playable maps of real-world locations through an open-source tool called Arnis, developed by the user louis-e. This tool replicates cities, roads, and landscapes using geospatial data from OpenStreetMap, functioning on both Java and Bedrock versions of the game. Arnis is built in Rust and features a user-friendly graphical interface with a command-line mode available. Users can select a location to transform it into a Minecraft world without needing mods or advanced programming skills. The project is open-source, inviting contributions from users. Arnis effectively turns Minecraft into a "playable Google Maps," enabling exploration of real locations while adhering to the game's rules.

Android 17 Beta 4 arrives with post-quantum cryptography and new memory limits

On April 16, Google released Android 17 Beta 4, concluding its beta phase and focusing on app compatibility and platform stability. Developers must finalize updates for Android 17 to avoid delays when the stable version is released. Key behavioral changes for apps targeting Android 17 include: - Large-screen resizability restrictions, preventing apps from opting out of maintaining orientation, resizability, and aspect ratio constraints. - Expanded restrictions on dynamic code loading, requiring native files loaded via System.load() to be read-only. - Certificate Transparency is enabled by default. - Local network access is restricted by default, with a new ACCESSLOCALNETWORK permission for persistent access. - Stricter rules on background audio interactions, including playback and volume change APIs. Android 17 introduces per-app memory limits based on device RAM to target memory leaks and anomalies, with minimal impact expected on app sessions. Developers can check for memory limit impacts via ApplicationExitInfo and utilize profiling tools in Android Studio Panda. An on-device anomaly detection service monitors resource-intensive behaviors and provides profiling artifacts. Additionally, the Android Keystore now supports ML-DSA for quantum-safe signatures, allowing developers to generate keys and create signatures within secure hardware.

Minecraft 26.2 Snapshot 3

In version 26.2, a new feature called sulfur spikes has been introduced, which generates naturally in sulfur caves. These spikes can form stalactites when placed on the ceiling and stalagmites when on the floor. They can be combined to create longer formations and will merge if placed adjacent without pressing the shift key. Stalagmites will break if not anchored, and stalactites will fall if unsupported. Thrown tridents can break sulfur spikes. The Potent Sulfur block can no longer be crafted back into sulfur blocks, and several block textures have been updated. The Sulfur Cube can no longer be picked up by boats. Sound effects for Nautilus jets and recoveries have been updated. The Data Pack version is now 102.0, and the Resource Pack version is 86.0. The minecraft:bed block entity has been removed, and entity predicates have been restructured for simplification. New block textures for sulfur spikes have been added. Several bugs have been fixed, including issues with axolotls, emissive textures, client crashes, and leads disappearing from sulfur cubes. Snapshots for Minecraft: Java Edition are available for installation, with a reminder to back up worlds.

Minecraft 26.2 Snapshot 3 Introduces New Sulfur Spike Blocks

The Minecraft 26.2 Snapshot 3 introduces Sulfur Spike blocks, which generate naturally on Sulfur blocks in the Sulfur Cave biomes. These blocks can form stalactites when placed on ceilings and stalagmites when placed on the ground. Players can combine two Sulfur Spikes to create elongated formations. Falling stalactites can damage players, and if there are no blocks above or below them, they will break and drop. Players can also break these spikes using a Minecraft Trident. Additionally, Potent Sulfur blocks can no longer be reverted back to Sulfur blocks, and the Sulfur Cube mob is no longer transportable via boats. Texture updates have been applied to several blocks, including Chiseled Cinnabar, Chiseled Sulfur, Cinnabar, Cinnabar Bricks, Polished Cinnabar, Polished Sulfur, and Sulfur Bricks.

This developer squeezed a full Minecraft server onto an ESP32, and it actually works

A developer named angelthebox has created a Minecraft server called Macerun that runs on the ESP32-S3 microcontroller, using Minecraft version 1.16.5 rewritten in C. Key features include the ability for players to join the server, explore the world, place and break blocks, procedural world chunk generation, basic crafting mechanics with 2x2 recipes, in-game chat, and tracking of basic physics, health, and hunger. Changes to blocks are saved to the chip's flash memory. However, the server lacks mobs, 3x3 crafting recipes, and the ability to retain player inventories and positions after exiting. The source code is available on the Macerun GitHub page.

Minecraft Java Snapshot Introduces New Mob and Sulfur Caves Biome

The Minecraft Java snapshot, named Chaos Cubed, introduces the Sulfur Caves biome, featuring Sulfur Springs and blocks of Sulfur and Cinnabar. It includes a new block called Potent Sulfur, which generates gas bubbles causing nausea and can be crafted from nine regular Sulfur blocks. A new mob, the Sulfur Cube, can absorb nearby blocks and transform into a ball-like state, with nine behavior types affecting its interactions. Adjustments have been made to Beds and Slime Blocks, allowing Slime Blocks to continuously bounce mobs when air drag is removed. The rendering system has transitioned from OpenGL to Vulkan for optimized graphics processing, while OpenGL remains available for older hardware. The snapshot is available for Java edition users and can be tested in the Bedrock preview, with a full release expected in June.

Minecraft’s powerful new mob just arrived in Java, and I can’t wait to see what players build

The Minecraft Chaos Cubed update has been released for the Java edition, introducing the Sulfur Cube mob and the Sulfur Caves biome. Players can find Sulfur Springs in the Overworld, leading to vibrant underground landscapes with Cinnabar and Sulfur blocks. A unique block called Potent Sulfur generates gas bubbles that can induce nausea. Crafting Potent Sulfur requires nine regular Sulfur blocks. The Sulfur Cube can absorb nearby dropped blocks and transform into a 'ball-like' entity, with nine distinct behavior archetypes affecting movement dynamics. Mojang has also adjusted the behavior of Beds and Slime Blocks upon collision, allowing Slime Blocks to bounce mobs indefinitely. The update transitions from OpenGL rendering to Vulkan for improved performance, while OpenGL remains available for older hardware. The Minecraft 1.26.2 snapshot is live, with a full release expected around June.
