I finally found the best personal knowledge management tool on Android after years of switching back and forth

The author explored various personal knowledge management (PKM) tools on Android and initially avoided Obsidian due to dissatisfaction with its earlier mobile app versions, which felt cramped and outdated. However, after revisiting the redesigned Obsidian app, they appreciated its modern user interface and improved usability. Obsidian's use of plain Markdown files allows for better file management and future-proofing of notes. The app supports both quick capture of ideas and deeper exploration through linking notes and creating a cohesive knowledge base. Features like Quick Note, Daily Note widget, and Graph View enhance its functionality. Data syncing requires some setup, with options for Obsidian Sync or third-party solutions. Ultimately, Obsidian stands out as a customizable and long-lasting PKM tool for the author’s workflow.

How Five PostgreSQL Optimizations Sped Up Our Dashboard

The dashboard operates on a Django monolith with PostgreSQL and is transitioning to ClickHouse for denormalization. The initial p50 metric was 0.7 seconds, but the p95 was 8 seconds, which was reduced to 1 second. Observability tools were established to monitor performance, and slow HTTP requests were identified using OpenTelemetry traces. Optimization techniques included late joining, asynchronous counting, creating a PostgreSQL replica for read operations, and improving full-text search. Denormalization was explored to enhance filtering performance by creating composite indexes. The production stack was upgraded to PostgreSQL 18, which provided incremental performance improvements. The final p95 value achieved was 1 second, below the target of 3 seconds.

The Fable reboot won’t have horns and haloes because of its ‘nuanced and complex’ take on morality, and also because you’re going to constantly reinvent yourself

The upcoming reboot of Fable by Playground Games will feature a nuanced and complex approach to morality, moving away from the traditional binary of good and evil. Characters in the game will have their own unique moral frameworks, leading to diverse interpretations of player actions. The game will not have a single visual representation of morality, allowing players to craft their hero's identity anew with each settlement visited. This design philosophy emphasizes the fluidity of identity and personal exploration, rather than a fixed reputation system.

I played Modern Warfare 4 at Infinity Ward, let’s talk about it

Infinity Ward is set to release Modern Warfare 4, its first entry in the franchise in four years. The game will feature the return of the DMZ extraction mode and is set in South Korea. It introduces apex attachments that fundamentally alter a gun's identity, with unique attachments for each weapon unlocking at full level. Movement mechanics have been revamped for a more fluid experience, allowing rapid mantling and smoother transitions. The initial maps follow a classic three-lane structure but lack innovation. The Gunfight mode returns, now expanded to 10v10 with dynamic maps. Quality-of-life enhancements include improved FOV, depth of field adjustments, refined muzzle smoke/flash effects, and improved hipfire mechanics. Loadouts have been simplified to five attachments per weapon and a standard three-perk system, allowing for more personalized gaming experiences.

UT Dallas class uses Minecraft to help students get into medical school

A young intern addresses the concerns of a first-time patient with tingling sensations, dizziness, and unusual fatigue, which may indicate conditions like multiple sclerosis or neuromyelitis optica spectrum disorder. The intern consults with a nurse and an attending physician in a virtual environment created using the game Minecraft, as part of a pre-med class at the University of Texas at Dallas. The course, titled Experiential Medical Reasoning, aims to prepare students for the MCAT by providing hands-on learning experiences in a simulated hospital setting. Students like Sahar Bavandi and Omar Choudhry engage with virtual patients and diagnostic tools, enhancing their understanding of medical concepts and improving their performance on tests. Dr. Eric Kildebeck, the course instructor, has noted significant improvements in student performance and plans to develop additional Minecraft-based educational games focused on biology and chemistry.

I’ve used Pixel Weather for 2 years — here’s why I’m ditching it for Gradient Weather

Google's Pixel Weather app was launched with the Pixel 9 series in 2024 and is known for its clean interface and robust pollen tracking. However, the author has shifted their preference to Gradient Weather, an Android weather app that aggregates data from multiple sources for improved accuracy. Gradient Weather features an intuitive bar graph for hourly forecasts, user-friendly color-coded alerts, and additional functionalities like a sunrise and sunset widget, moon phases, and a compass. Its map functionality includes filters for various weather conditions and allows users to report real-time weather phenomena. The app offers extensive notification customization and aesthetic options, including theme modifications and widget arrangements. While Pixel Weather has advantages such as a pollen tracker, Gradient Weather's premium features and rapid development make it a compelling choice for Android users.
