I spent an entire day with a fan-mod of North Korea’s homegrown operating system, and I’m sorry to say it’s not a Windows killer yet

RedStar OS 3.0 is a national Linux distribution from North Korea, designed primarily for the DPRK's intranet, Kwangmyong. The modified version, RedStar OS 3.5, claims to enhance the original by removing spyware and providing easier access to root privileges. The author faced challenges in accessing the system, implementing a 64-bit kernel, and connecting to the broader internet due to the OS's limitations. Attempts to run the game Tux Racer were unsuccessful due to compatibility issues, resulting in a system with only basic applications available. The overall experience highlighted the shortcomings of RedStar OS 3.5 in terms of practical usability, especially for gaming.

PostgreSQL 18 on Amazon Aurora and Amazon RDS: Performance enhancements

PostgreSQL 18 addresses common performance challenges for users, including managing query performance across composite indexes, diagnosing memory spills in materialized Common Table Expressions (CTEs), and upgrading major versions without plan regressions. Key enhancements include skip scan optimization for multicolumn indexes, improved EXPLAIN functionality, and optimizer statistics that persist through major version upgrades. Skip scan optimization allows PostgreSQL to efficiently utilize multicolumn B-tree indexes even when leading columns are not specified in the WHERE clause, significantly improving query performance. The EXPLAIN command has been enhanced to include buffer statistics by default, providing deeper insights into query execution and resource usage. PostgreSQL 18 also introduces visibility into the storage of materialized nodes in query plans, indicating whether intermediate results were stored in memory or spilled to disk. A new metric, Index Searches, has been added to EXPLAIN ANALYZE output, indicating how many times the database traversed the index tree during query execution. Additionally, Self-Join Elimination (SJE) automatically detects and removes unnecessary inner joins of a table to itself, optimizing query performance. The autovacuum mechanism has been improved with the introduction of autovacuum_vacuum_max_threshold, which caps the number of dead tuples that can accumulate before autovacuum triggers a VACUUM, addressing issues with large tables. The vacuum_truncate parameter provides a server-wide control point to disable VACUUM’s file truncation behavior, reducing locking issues on busy systems. PostgreSQL 18 also separates the allocation of autovacuum worker slots from their usage, allowing for dynamic adjustments to autovacuum_max_workers without requiring a server restart. Finally, new columns in pg_stat_all_tables track cumulative time spent on maintenance operations, providing better insights into maintenance overhead for each table.

How to bring the best Android 17 features to any Android phone today

Android 17 introduces several features that enhance user experience and privacy, including the Bubbles multitasking system for managing multiple tasks, a Privacy Dashboard for easier navigation of privacy settings, and an “Expanded” Dark Mode for improved usability in low-light environments. Users of older Android versions can activate an “Extended” dark mode through developer settings. Additionally, the Twilight app mimics Android 17’s Comfort View to reduce eye strain by adjusting screen color temperatures.

‘[It] is going to change a lot about how games are made’: Epic merges Unreal Engine 5 with Unreal Engine for Fortnite to give game devs around the world Unreal Engine 6

Epic Games unveiled developments for Unreal Engine 6 at the State of Unreal event in Chicago, highlighting its evolution from Unreal Engine 5. The new engine will incorporate features from Fortnite and UEFN (Unreal Editor for Fortnite), which allows users to create game levels easily. Unreal Engine 6 will adopt open standards for tools, code, and APIs to simplify development across industries. The anticipated release is set for 2027, with early access expected by the end of that year. Verse, a new scripting language, will be central to the gameplay programming model, while C++ will remain foundational. The Scene Graph will replace the existing gameplay framework, and artificial intelligence will play a larger role, with the UE5.8 release introducing the MCP server plugin for deploying large language models.
