Pushup RPG is a free iOS/Android app that counts pushups (and squats, sit-ups; plank timed) in real time with on-device front-camera pose detection. Workouts power a fantasy RPG: defeat 48 foes across 8 biomes, earn XP and loot, and level up a hero via a three-path skill tree. Duel live for 40 seconds with a friend using two cameras, or climb global and country ladders in the Arena. No video leaves your device. No wearables or taps required; sign-in is optional.

IBM unveiled the first dual-architecture mainframe processor for IBM Z and LinuxONE, enabling Arm-native Linux to run alongside z/OS and Linux on IBM Z. Result of the April 2026 IBM–Arm collaboration, it lets Arm workloads run natively with IBM Z or LinuxONE without separate cores, while preserving IBM’s reliability and security. Built on 2nm with 11 cores >5.7 GHz, AI inference accelerators, on‑chip I/O, and a large cache, it scales to hundreds of cores and tens of TB memory. Bridges the Arm ecosystem with IBM enterprise workloads, expanding choice and AI acceleration.

Pants for Birds introduces ADSBee m1421, the world’s smallest dual‑band ADS‑B receiver module. It uses Semtech LR2021 for a compact, low‑power Mode S/UAT front end and TI CC1314 MCU, delivering under 60 mW and under 2 g in a 23.4×14.5×2.7 mm package. Open‑source firmware/schematics (GPLv3); outputs include GDL90, MAVLINK, JSON, CSBee, and raw packets. NDAA variant available; standard $48, NDAA $75, with volume pricing. Sold as module or via ADSBee 1421 Developer Kit ($95) with carrier board and USB programmer. Tools at adsbee.aero; not MLAT-ready, no EMI certification.

Revyl argues that as AI agents improve, verification and runtime validation become the bottleneck, not coding. The traditional linear loop (Idea–Design–Engineering–QA) is replaced by a loop focused on verified changes and observed results, driven by runtime signals from running apps. Design, engineering, and product roles increasingly converge. Revyl aims to build the missing pieces: capture behavioral evidence and runtime signals as core development inputs, integrate with existing tools, and start with mobile. Product development isn’t dead; it’s being rewritten.

In his ICML 2026 invited talk, Arvind Narayanan argues that AI will augment rather than automate work; progress shifts from model development to evaluation/monitoring and scaffolds. Over time, purely technical skills may wane; researchers focus on question-asking and conceptual progress, while industry values relational skills, domain knowledge, and judgment.

This guide explains serving Markdown to AI agents via content negotiation using Accept: text/markdown. The same URL serves HTML for browsers and clean Markdown for AI clients, letting agents skip navigation, scripts, and layout and focus on prose. Benefits: smaller payloads, less noise, faster first tokens. It covers testing (edge vs origin) and implementation (three steps: one server, two responses), plus guidance on Vary, q-values, 406, caching, and configs for Nginx, Caddy, WordPress, etc. Includes an AI agent support matrix and RFC references.

An incident-history dashboard filters GitHub incidents by service and severity to analyze reliability. Since March 2016 GitHub has had 1,125 incidents (≈24/mo), with an 8-day longest non‑incident streak (through 2025‑12‑31) and a peak month of 37 incidents in February 2026. It lists service uptimes (e.g., Repositories 99.93%, Code Scanning 99.81%, API Requests 99.59%), plus a severity split: 28 Critical, 186 Major, 911 Minor. Worst days are highlighted. Data from GitHub Status; not affiliated.

Actinide, a Dallas-based startup that builds its own isotope-separation machines, says it is the first company to produce HALEU (5–20% U-235) with its first-gen calutron. The lab-scale enrichment reached 15.38% U-235; the material would need fabrication into fuel pellets. This bypasses the DOE’s deconversion bottleneck for centrifuge-derived HALEU and strengthens domestic supply. Actinide had previously enriched ytterbium-176 and is building Fortitude, a second-gen separator estimated to have about half the throughput of the U.S. government's EM fleet. Founded Sept 2025; CEO Eric Olszewski; seed round Mar 2026 led by Onto Ventures.

Tariffs on Canadian goods are collected at the U.S. border and paid by American importers; customs logs show the duty actually collected. The page also offers a modelled, broader estimate of tariffs on all U.S. imports since 2025 (including energy) and, for those, a pass‑through to shelf prices is assumed. Canada’s counter-tariffs are paid by Canadian importers and show up in Canadian prices. Data come from public datasets; the only forecast is the household-cost figure based on a pass‑through assumption. The page includes filters by state, industry, product, and rate bands (15%, 25%, 50%).

CoMaps is a 100% offline, open-source mapping app built on OpenStreetMap data for emergencies. In Venezuela's earthquake response, volunteers used it to navigate without cell service, coordinating with ground teams and a distant command center. Updates previously took days, but decoupling map data from app releases enabled weekly global updates; Venezuela maps were available for responders. The tool bridges data and field workers, letting non-experts access volunteer-mapped data via HOT Tasking Manager. The goal is regional updates every 12 hours. CoMaps was developed with HOT to support humanitarian response.

Graze is joining Flipboard to accelerate Open Social and reorient the attention economy toward broader ownership. Open Social aims to diffuse platform power by letting people run their own social algorithms and monetize their curations. In 21 months, Graze has sent 41 billion posts to 12 million people, reinforcing their playbook. Surf will be the browser for open social feeds (Bluesky, Mastodon, Threads, RSS), while Graze powers the engine to build, tune, and monetize feeds without coding. The partnership preserves existing products and aims for an attention economy owned by workers, not kings.

An exhaustive reference of YouTube format IDs (itags) with video/audio codecs, resolutions, framerates, and whether they are DASH or legacy. It covers DASH video/audio variants (AVC/H.264, VP9, AV1, HDR/HFR), non-DASH formats, 360° and premium formats, and audio formats; explains the AI-based upscaling suffix -sr and notes deprecations/restrictions (POT tokens, YouTube Premium). Provides yt-dlp usage tips for archiving videos and audio, plus 2024–2026 format changes (e.g., removal of 599/600 for new uploads and ongoing updates).

A Scottish study linked proximity to WIAT urban woodlands with lower antidepressant and anti-anxiety prescriptions. Tracking about 129,000 people for five years, researchers found moving to within a 10-minute walk reduced antidepressant prescriptions by 10% and anti-anxiety prescriptions by 6%. The WIAT program, launched in 2005, has revitalized around 30,000 acres of accessible woodlands in deprived neighborhoods. Published in The Lancet Planetary Health, the findings support that modest green-space investments can boost mental health; WHO recommends green space within 1,000 feet of every home.
