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.

Overwatch Season 2 is “modernizing” old heroes, and I’m ready for a Pharmercy revival

The Overwatch Season 2 update will feature significant changes, including the return of the 'Pharmercy' duo with revamped abilities for original heroes. Mercy will receive a Flash Heal ability, enhancing her healing capabilities, while Pharah will gain Drift Thrusters to improve her maneuverability during Barrage. Reaper will have Dire Triggers as a standard ability to better engage distant targets. The post-match experience will be revamped with a new accolades system for player recognition and a shared lobby voice chat during the Play of the Game. Competitive play will see reduced ranking penalties for losses on new or reworked maps, and a system for automatic map selection based on player votes. Blizzard is also considering improvements to the hero bans system for future updates. Overwatch Season 2 is set to launch on April 14, introducing new character Sierra.

Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

This new app may free Galaxy Watch owners from Samsung’s phone-locked features

A new application called the GeminiMan Wellness Companion has been developed for Galaxy Watch users by Dante63, who previously created a patched version of the Samsung Health Monitor. The app allows users to record electrocardiogram (ECG) data from the Galaxy Watch, providing detailed reports and AI-driven analysis through a mobile app. It can track heart rhythm and rate, flagging abnormal rhythms, which the Samsung Health Monitor does not. Users can personalize their measurements with notes and create multiple profiles for different users. The app ensures data security through encryption and offers export options for ECG reports in CSV or PDF formats. Future updates will include blood pressure recording and additional health metrics like blood oxygen levels and sleep patterns. The development roadmap is available on the GeminiMan Wellness Companion GitHub page.

Windows is sabotaging your expensive hardware, and these are the biggest ways how

Modern PCs, even with mid-range hardware, can experience performance issues not solely due to hardware limitations but because of how Windows operates. The operating system runs numerous background services that consume resources, including Connected User Experiences and Telemetry, Diagnostic Policy Service, and Windows Error Reporting. These services log activity and send data to Microsoft, leading to unexpected CPU spikes and disk usage. Startup applications, such as Microsoft Teams and OneDrive, also contribute to longer boot times and increased resource usage. Users should monitor and limit these applications to improve startup performance. Legacy features like SysMain, Windows Search indexing, and automatic folder type discovery can hinder performance on modern systems, as they were designed for older hardware and can cause unnecessary disk activity. Microsoft services like Copilot and OneDrive continuously run in the background, consuming memory and CPU resources, which affects overall system performance. Windows' power management settings prioritize energy efficiency over performance, leading to inconsistent responsiveness and delays during tasks. This conservative approach impacts various components, making the system feel sluggish.

Apple pulls Jack Dorsey’s messaging app from the Chinese App Store

Apple has removed the messaging app Bitchat from the Chinese App Store at the request of the Cyberspace Administration of China (CAC), which cited regulatory concerns. Bitchat, originally launched as Bitchat Mesh and developed by Jack Dorsey, allows anonymous, peer-to-peer communication using Bluetooth-based mesh networking, without relying on internet-connected servers. The app gained popularity in regions with internet shutdowns and social media restrictions. The CAC has alleged that Bitchat violated regulations requiring security assessments for apps that can influence public opinion or mobilize users. Dorsey confirmed the removal on X but has not disclosed any plans for Bitchat's return to the App Store.
