Started in 2021 within Microsoft’s Azure Databases team, the group began as casual, paper-based discussions on database internals and gradually broadened to broader systems topics. It evolved from one-off papers to guided series (e.g., Red Book readings) and eventually to the Microsoft Systems Reading Group, expanding beyond databases toward datacenter foundations for 2026 (The Datacenter as a Computer). Key takeaways: be consistent, let scope grow organically, use multi-session series, co-organize, and welcome unprepared attendees. Benefits include cross-team learning and connections.

Avalonia reveals the first preview of its Avalonia backend for .NET MAUI, enabling MAUI apps to run on Linux and WebAssembly. Getting started: create a MAUI app, add Avalonia.Controls.Maui.Desktop, target net11.0, and use UseAvaloniaApp; no bootstrapper needed. Avalonia 12 adds new navigation APIs/controls and a fully drawn UI, matching MAUI parity across platforms. They tested with MauiPlanets, 2048, control gallery, AlohaAI, and MyConference. Native vs drawn both supported. Also compatible with GraphicsView, SkiaSharp.Views.Maui, and Mapsui.Maui. Looking ahead: Maui.Essentials on Avalonia, WinUI interoperability, more drawn-control patterns, and .NET 11 completion. GitHub repo.

Love stems from NixOS’s deterministic, declarative, reversible package manager, Nix. It lets you define an entire OS as a single source of truth, rebuilds and rolls back changes, and avoids creeping system drift. It enables isolated, reproducible experiments with flakes and nix develop, supports cross-platform use (macOS, Linux, FreeBSD), and smooths toolchain provisioning without mutating the base system. It also offers deterministic deployment with layered images and complements modern, fast-changing tooling, including LLM coding agents.

The essay argues that claims of code's death are exaggerated. AI can translate English into runnable code, enabling 'vibe coding' that sharpens ideas via AI artifacts, but vibes mislead without abstraction. Complexity—especially in live collaboration—remains hard, requiring better abstractions (functional programming, React, Tailwind) to compress and manage ideas. AGI will eventually help create superior abstractions and tooling, not erase coding; code itself remains a central, poetic artifact. The author cites Slack diagrams, Opus 4.6, and a full-stack React demo to illustrate progress and the enduring value of code.

You're not your job. Our identities are narratives we tell about ourselves, and we too easily equate self-worth with work. True value lies in relationships and presence: warmth first, then competence. AI will automate tasks, but cannot automate genuine listening or being with someone. Meaning comes from I-You, not I-It; regrets at life’s end hinge on relationships, not earnings. If your title vanished tomorrow, would you still be you? If yes, you’re in the right place—cultivate presence and human connection.

Manyana is Bram Cohen’s demo of a CRDT-based version control system where merges always succeed and conflicts are informative rather than blocking. History is stored as a weave containing every line with add/remove metadata, so merges don’t rely on a common ancestor. Rebase can replay commits onto a new base while preserving full history via a primary-ancestor annotation. It’s a ~470-line Python prototype, not a full VCS yet, with public-domain code and a design document in the README.

Felix argues Wayland is not developer-friendly despite being billed as the future. While it may be nicer for users than X11, the programming model is chaotic: a callback-heavy, object-oriented protocol with a fragmented ecosystem. Opening windows or drawing requires extensive boilerplate, registry globals, wl_display_roundtrip/dispatch, and handling extensions (xdg_shell, WlrShell, etc.). The protocol is generated from XML via wayland-scanner, adding more hurdles. As a user Wayland is fine; as a developer it's a “fucking disaster” compared to Win32 or X11.

Why Lab Coats are White traces the coat's rise from Victorian black frock coats to a white, washable uniform symbolizing cleanliness and trust. In 19th-century England, surgeons wore dark garb to hide stains; the hygienist movement and antiseptic practices pushed for visible cleanliness. White coats were practical: cheap, washable, mass-produced, enabling hospitals and laboratories as medicine and lab science merged. Over decades they signaled professional belonging in guilds, aided by art and photography. Today PPE explores new fabrics and colors, but the white coat endures as a cultural symbol amid debates about function.

IBM researchers Charles H. Bennett and Gilles Brassard, sparked by a 1979 encounter, co-created BB84, the first practical quantum key distribution. They showed quantum information cannot be copied without disturbance, making eavesdropping detectable and security grounded in physics, not math. The work helped launch quantum cryptography, quantum teleportation, and a line of IBM quantum research. Faced with Shor’s 1994 threat to classical cryptography, the method gained urgency. In 2025 they were named co-recipients of the ACM A.M. Turing Award, the first to honor quantum research.

An FPGA reimplementation of the Voodoo 1 using SpinalHDL shows how modern RTL tools can make a fixed-function GPU tractable for a single person. The Voodoo’s complexity lies in fixed rendering behaviors and pipeline timing, not programmability. The author defines four register behaviors (FIFO, FIFO+drain-stall, Direct, Float) and encodes them with an extended RegIf, letting the register map drive hardware like a PCI FIFO. Debugging with netlist-aware conetrace revealed subtle errors from multiple small mismatches (precision, perspective rounding/LOD, and dither-based blend). The tools let you query execution rather than skim waveforms.

Decades-long study of 130,000+ people over 40 years found regular moderate caffeinated coffee or tea linked to an 18% lower dementia risk vs rarely drinking caffeine. About 2–3 cups daily, with consistency more important than high intake. Data from the Nurses’ Health Study and Health Professionals Follow-Up Study showed 11,033 dementia cases. Findings are observational, not causal. Possible explanations include improved blood flow, reduced inflammation, and brain signaling effects, though lifestyle factors could confound. Not a miracle cure, but caffeine might help preserve memory a bit longer.

The piece argues that "convincing" (logic aimed at a universal audience) is not enough to move organizations. Engineers often present technically airtight proposals that offend no one but fail to persuade the actual stakeholders whose incentives, fears, and constraints matter. Persuasion blends logical argument with credibility and emotional resonance, tailored to a specific audience (SREs, PMs, juniors) and their context. Rhetoric matters: trust, timing, and showing how a change serves what they care about. Conviction plus persuasion creates commitment; authority alone yields only compliance.

Crack is a macOS menu-bar app that turns lid movement into squeaky sounds. It reads the built-in AppleHID lid sensor at 60fps to detect movement, with pitch varying to lid velocity for slow creaks and fast snaps. Seven synthesized sounds—haunted door cracks, cat meows, alien whispers, whale songs, wind—play in real time. The app is under 1 MB, uses little CPU, and is built in Swift with AVAudioEngine. Open source under the MIT license, signed and notarized by Apple, with no telemetry. Made by Ron Reiter; source on GitHub.
