TRMNL's AI Agent lets you build plugins without coding. In public beta, it requires an OpenRouter API Key (credits loadable via their billing portal); Claude, Tavily, or other OpenRouter options are supported. Quickstart: enable Agent, configure model and keys, create a private plugin, edit markup, and prompt the agent. The agent uses a system prompt and has access to tools such as web search, data refresh, and API endpoints. MCP plugins can run with a private API key for local tooling. Models include Gemini, Codex, Claude Sonnet, Kimi, Llama OSS. Plugins cost ~$1-3; publishing isn’t available yet. Contact support.

Pareto is a robotics data platform modeled on YouTube. An episode bundles multiple sensor streams, camera feeds, actions, and timestamps into a connected unit searchable via synchronized playback. The design emphasizes: 1) reliable uploading with versioned source files and a final manifest; 2) a pipeline that derives thumbnails, previews, embeddings, and indexes from the original; 3) long-running jobs managed as durable workflows with sharding and lazy computations; 4) separate storage for raw data, metadata, and vectors; 5) streaming only the needed byte ranges for fast, synchronized viewing. It's open-source and scalable-by-default rather than starting at scale.

Slater is a low-memory, Bolt-compatible graph database designed for very large graphs. It serves graphs from on-disk generations with bounded RAM, via a cache budget, and supports a writable delta layer over an immutable core for live, durable writes. It pairs the graph engine with disk-native vector search for embeddings (RAG) and supports storage backends: local filesystem, S3, or GCS. It exposes Cypher and ISO GQL queries, builds offline generations with slater-build, and ships as Docker images under the Apache 2.0 license.

Apple's Private Cloud Compute (PCC) SOC 3 audit reports are independent examinations of PCC provisioning controls by an AICPA‑accredited auditor. They provide reasonable assurance that PCC security, processing integrity, confidentiality, and privacy commitments and requirements are designed and operated effectively. The reports cover provisioning, ongoing verification, and protection of information in compute nodes and are issued quarterly on a rolling 12‑month basis. Available periods end Jul 31 2025, Oct 31 2025, Jan 31 2026, and Apr 30 2026. Not covering Apple AI services. For questions, [email protected].

Space Project is a self-running space-economy simulator in Rust + Bevy. An agent-driven world with ~485 entities (ships, facilities, populations, factions, celestial bodies) that trade, mine, deliver contracts, refuel, and manage morale. Ships use a GOAP planner; markets price commodities via a coverage-based model; facilities produce and evolve; populations migrate. Runs as a single native binary with no scripted story, plus an inspector for live debugging. Persistence via SQLite; Bevy-based client; MIT license. Fork and contribute via CONTRIBUTING.md.

Block's Jack Dorsey unveils Buzz, an open-source workspace that unifies team chat, AI agents, and Git hosting behind a single identity system. Built on self-hostable Nostr relays, Buzz signs every event so humans and AI agents share auditable identities. It offers channels, direct messages, shared canvases, and a built-in Git forge where a feature branch can become a channel with patches, CI results, and reviews preserved in one record. It is early, with incomplete mobile and workflows, and undecided adoption beyond Block.

An in-depth look at the H-1B program shows how a modest 1990 visa became a vast, loophole-rich pipeline dominated by Indian IT workers. The dossier tracks a nesting of pathways—H-1B, H-4, OPT, L‑1, and green cards—that together house about 1.28 million people in the U.S., with 399,395 H-1B approvals in FY2024 and a 65k+20k cap. IT dominates (~64% of approvals). Major Indian firms (Infosys, TCS, Wipro, Cognizant, HCL) drive the curve. It highlights backdoors (OPT, L-1), per-country wait times, compliance gaps, and wage suppression as core dynamics.

Shows how to deploy a cost-efficient, production-ready K3s cluster on Hetzner Cloud with the terraform-hcloud-kube-hetzner project. Uses MicroOS on all nodes, three control planes and three workers across three sites, with private networking and optional load balancers. Covers cost optimizations (single load balancer or MetalLB; remove public IPs) and a practical Terraform rollout: init, plan, apply; fetch kubeconfig and verify with kubectl. Integrates Hetzner tooling (hcloud CCM/CSI), automated upgrades with Rancher SUC, Kured reboots, and backups to S3-compatible storage. A reproducible, sovereign setup for production workloads.

uhubctl is a command-line tool to control USB hub per-port power switching on supported hubs. It reports compatible models, and lets you turn specific ports on/off, cycle, or toggle power with commands like 'uhubctl -a off -p 2' (and -l to select hub). It works on Linux (with udev rules), macOS, and to some extent Windows; you may need to compile from source for latest version. The page includes installation, usage, Linux permissions, caveats for Raspberry Pi hubs, daisy-chaining hubs, and a FAQ and a hub compatibility table.

Imagin RAW is a lightweight native macOS app that serves as a faster, more efficient alternative to Adobe Bridge for browsing, culling, and organizing RAW photos. It uses SwiftUI for the UI, LibRaw for RAW decoding, and CoreImage as a fallback. It supports multi-root folders, real-time file-system monitoring, rating and labeling via XMP, RAW+JPEG dedupe, and a session-based rejection workflow. Compared to Bridge, it’s ~9 MB, near-instant launch, and low memory usage. Features include SD-card ingest, Spotlight search, and an iOS companion in development. MIT license.

CodeAlmanac is a living wiki for codebases used by AI coding agents. It stores wiki pages as Markdown in your repo (almanac/), enabling context like decisions, invariants, and workflows to live with code. It runs locally (Python 3.12+), using Codex or Claude via the Yoke SDK. The CLI includes init, ingest, garden, sync, update, serve, and health, plus a local viewer and topics. Background macOS launchd jobs keep data fresh (sync, garden, update). Telemetry is optional. A repo becomes a wiki when almanac/topics.yaml and README.md exist.

Phantomdrive is an open-source USB drive that presents as an 8 GB volume; a hidden encrypted partition is revealed via a plaintext trigger (password:...). It uses CH569 hardware, SD storage, and AES-256 with a per-device salt sourced from the USB serial and 100k SHA-256 KDF rounds. It supports AES-CTR or AES-XTS (XTS is slower). The firmware snoops writes to detect the password trigger, and the case is epoxy-sealed for tamper resistance. Open-source project with design notes, performance (~9 MB/s write / 20 MB/s read with CTR; ~6/10 MB/s with XTS), and preorder support.

Meta’s SAM 3 and DINOv3 power SYNAPS-I, a Genesis Mission effort to transform image segmentation and real-time data analysis at DOE beamlines. Fine-tuned on scientific imaging data and deployed on 300 A100 GPUs at national labs, the pipeline delivers semantically labeled 3D volumes in about 15 minutes, enabling interpretation while experiments run. In a grapevine drought study, it automatically segments xylem vessels from micro-CT scans, dramatically speeding insight from weeks to minutes. The work is open source and run on secure on-prem systems to accelerate discovery across facilities.

Why Are There No Empires in Age of Empires? argues that an empire is a core ruling group extracting resources from a diverse periphery. AoE misrepresents this by making conquerors erase populations and homogenize empires; real empires rely on diverse peoples, cultures, and labor. Rome illustrates this: its army relied on socii and provincials, and diversity enabled expansion and revenue, not mere conquest. Games often underdevelop polyethnic mechanics; conversion or cultural genocide is not the norm. The piece concludes AoE is an abstraction; modern nation-states are an unusual deviation._future posts will further examine imperial mechanics.

Amid a nurse shortage, UAB is actively welcoming men into nursing, where nearly 1 in 6 students and about 1 in 5 faculty are male. The piece follows students like Ethan Stinson and Hatim Nasser who already have jobs in hospital wards. The school uses male-focused marketing, high‑school outreach, and men’s nursing groups to broaden access. Stereotypes persist, but nursing is becoming more technical and in demand; advocates hope to formalize men’s health as a nursing specialty to widen opportunities.
