Trunk-Based Development is a source-control approach where all code lives on a single trunk/main. Long-lived feature branches are discouraged; teams either commit directly to trunk (small teams) or use short-lived, single-developer branches for CI and code review, guarded by feature flags or branch by abstraction. The goal is a releasable trunk at all times to enable continuous integration and delivery. Release can be from trunk or via just‑in‑time release branches for higher throughput. Requires build servers to prevent breaking builds; practiced by Google and others; described in Continuous Delivery and The DevOps Handbook.

Colorado SB 26-051 shifts online age verification from websites to the OS/app-store layer. OS providers would collect a user’s birthdate, generate an age bracket signal, and expose it to apps via an API for developers to use. It aims to bypass direct publisher verification, reflecting prior attempts (SB 25-201, SB 25-086) that stalled over First Amendment, privacy, and feasibility concerns. Supporters say centralized mobile ecosystems enable practical enforcement; critics warn of open-web bypasses, constitutional risks, and no universal ID or mandatory parental controls. The bill awaits a committee hearing.

Microsoft researchers demonstrated glass-based data storage that could stay readable for 10,000 years or longer. They encode data in borosilicate glass by ultrafast laser bursts that create plasma-induced nano-explosions, deforming the glass, with reading done via a microscope. A 12 cm square stores about 4.8 terabytes (~two million books). The method requires specialized write/read equipment but is maintenance-free and temperature-insensitive, offering near-permanent archival storage. This deployable approach, part of Project Silica, uses borosilicate instead of fused silica for practicality and density.

Ajay Chavda's Mojo Dojo SEO reports that Meta's automated identity checks ban agency work accounts for paid ads within minutes to hours, even for long-standing advertisers with clean histories. Despite hiring senior paid ads specialists and compiling verifications, every attempt ends in a ban; appeals are unusable because you’re locked out. The result: lost client campaigns, harmed staff, and disrupted operations. They call for a manual onboarding pathway for verified agencies, human login support, and acknowledgment of false positives, asking others and Meta employees to engage.

PIrateRF turns a Raspberry Pi Zero W into a portable RF signal generator with its own Wi‑Fi hotspot, controllable in a browser across 12 transmission modes (FM with RDS, Live Microphone, FT8, RTTY, FSK, POCSAG, Morse, Carrier, Frequency Sweep, SSTV, Spectrum Paint, IQ). It supports safe indoor testing at milliwatts, requires amateur-radio licensing per local rules, and provides a pre-built image or manual setup, plus a web interface with presets; licensed under WTFPL.

Conan now supports packaging configuration (remotes, profiles, settings, hooks, commands, plugins) as Conan packages via conan config install-pkg, enabling versioned, reproducible, traceable configuration distribution across CI and dev machines. You can install a specific version (myconf/1.2) or ranges, share config with same package server as libraries, and create per-platform configs using settings. A simple conanconfig.yml can reference packages and auto-install. Lockfiles can record exact config versions used for reproducibility; the core.package_id:config_mode option controls whether config affects package IDs, improving traceability. This simplifies managing multiple configurations and promotions.

A GitHub issue reports Claude Code 2.1.1 causing excessive token usage, up to 4x+ faster than prior versions. User h3d0 on Linux observes rapid spending after updating to 2.1.1, hitting 5-hour usage limits despite MAX plan and previously low weekly cap. Logs show lock acquisition failures for /home/oleh/.local/share/claude/versions/2.1.1 and aborted requests. Plan/Opus mode drains usage quickly, unlike Heiku. The issue requests investigation into the sudden surge starting with the update.

An article from TigerBeetle argues for a naming convention to minimize indexing errors. Use count for the number of items and index to refer to a particular item, with the invariant index < count. Treat size as the byte-size of a type times count; offset is the bytewise index. Avoid length due to ambiguity. Employ big-endian naming so related names align (source/source_index, target). Examples from NodePool and an ewah decoder illustrate how consistent naming helps catch mistakes. It’s a defense-in-depth approach alongside strong typing.

GitHub feature request for indexed transcript references in compaction summaries to prevent data loss during auto-compaction. Problem: summaries are lossy and lack pointers to the original transcript on disk, so Claude forgets details mid-task. Solution: Phase 1—annotate compacted blocks with transcript line ranges (e.g., [transcript:lines X‑Y]); Claude can recover exact content by reading those lines on demand. Phase 2—cross-session recovery across ~/.claude/projects; UX favors current session with optional prior-session search. Benefits: zero overhead until recovery, no extra storage, scalable context restoration.

OAuth is a standard for delegated authorization: with user consent, a multi-use secret is issued to a delegate, who can use it to act on the user’s behalf. The core idea is simple; OpenID Connect adds authentication on top, akin to a magic-link. The history—password-free sign-in for mobile/alternative clients—drove the move from insecure patches to standardization. OAuth is best viewed as a framework with necessary security and UX constraints, not a single rigid spec. Focus on the goal you’re trying to achieve; the how follows from that.

Page refresh breaks the Claude-style SSE stream, losing in-flight tokens and forcing a full rebuild of history. A Minimal Chat UI built on WebSockets/Pub/Sub shows seamless resume without persistent state. The point isn't that SSE is inherently bad, but that its capabilities are limited for reconnection, multi-device, presence, and efficient hydration. The author argues the real art of the possible is a pub/sub transport for AI, where one message collects tokens via append, and updates on reconnect provide a seamless, scalable experience without token-by-token streaming.

Cord enables agents to build and evolve a coordination tree at runtime instead of following a pre-defined workflow. Unlike static frameworks (LangGraph, CrewAI, AutoGen, OpenAI Swarm, Claude loops), Cord lets one agent spawn subtasks and fork results, resolves dependencies, and incorporate human input via asks. Its five primitives (spawn, fork, ask, complete, read_tree) plus a protocol for dependency resolution, authority scoping, and lifecycle are enforced by a MCP server; the protocol is generic, so it can run over Claude, GPT, or Postgres. An API-migration example shows dynamic decomposition, parallel tasks, and analysis. The project, with ~500 lines and tests, is open-source.

Git tracks files, not directories. To ensure a directory exists in clones, you can track it with a placeholder. The .gitkeep approach uses an empty .gitkeep and a .gitignore that ignores everything except .gitkeep, but it requires two files and can confuse. The preferred method is to place a .gitignore inside the directory containing '*\n!.gitignore', so all files are ignored except the .gitignore itself, allowing the directory to be tracked with one file and survive renames.

Lexega provides a guardrail layer for SQL by turning SQL into deterministic, actionable signals before execution. It tokenizes/parses SQL (including Jinja/dbt), extracts semantic facts (read/write tables, grants, policy changes), and emits signals. Built-in and custom YAML rules map signals to severities and messages; policy evaluation yields a decision to allow, warn, or block. The process is deterministic; same input yields same signals. Includes semantic diff to catch risky changes, supports dbt templating with automatic rendering, and lets you override or extend rules. Outputs a decision.json for CI.

Bluesky’s ATProto paints an open, user-owned data promise, but in practice most data sits on Bluesky-run Personal Data Servers (PDS). Self-hosting is uncommon and migration tools rely on future access. New ATProto apps deepen dependence on Bluesky, creating a centralization flywheel rather than true distribution. Bluesky controls key layers—the Relay, AppView, and DID Directory—giving an acquirer power to disable exports, cut off apps, or insert ads. Despite rhetoric, true decentralization is illusory; economic incentives favor consolidation.
