An battered Samsung A70, after a year in a bag of rice, is repurposed as a personal web server. With a nonfunctional touchscreen, Android’s input options and external hardware enable a usable setup: USB-C powered hub, wired Ethernet for reliability, and seamless IP retention as the device switches between Wi‑Fi and Ethernet. After trying an AMPPS stack, the author builds a Cordova app around NanoHttpd to gain full hardware control (Bluetooth, SMS, USB‑Serial). Running for over a year, it’s proxied via Cloudflare. Future goals include FTP server/client and SMTP; open-source under the Qik project.

King’s College London–led research (Cambridge Law Journal) shows hospitals and universities are running late-stage trials repurposing existing, generic drugs at less than 10% of pharma costs—up to 90% cheaper. This outside-patent, “hidden” system can deliver affordable treatments, e.g., a cancer drug for blindness, a breast‑cancer drug for prevention, and an old anti-inflammatory for Covid. Lower barriers—less expertise, risk, and capital—plus grant/ethics approvals and different incentives drive it. Governments are recognizing and funding the approach to boost access and reduce costs.

Velvetyne publishes Jgs Font, a free monospaced typeface by Adel Faure as a tribute to ASCII artist Joan G. Stark. The article explains ASCII Art as 'non-graphical graphics' created from keyboard characters, outlines its history from Usenet/BBS to Unicode, and situates text-mode art within broader mechanized text practices. Jgs Font's design emphasizes bitmap-like, exaggerated glyphs that can be combined to form continuous lines and patterns; it includes ASCII, Latin-1 Supplement, and code page 437 glyphs, is available under a free license, and invites use and modification with credit.

MWI’s War Books summarizes the USMC Commandant’s 2026 Professional Reading List, divided into Heritage, Innovation, Leadership, and Strategy (Foundational works omitted). Highlights include Heritage: First to Fight; This Kind of War; The American War in Afghanistan; With the Old Breed. Innovation: The Arms of the Future; The Origins of Victory; Generative AI for Leaders. Leadership: Matterhorn; Generals and Admirals, Criminals and Crooks. Strategy: Ender’s Game; The New Makers of Modern Strategy; The Russian Way of Deterrence; Ground Combat. Commandant’s Choice: Once an Eagle. Reading remains vital amid changing media.

GitHub’s reliability issues and growing fragmentation push developers toward alternative forges. The article promotes Tangled, a Git forge built on the AT Protocol that lets you self-host your data while a central app aggregates it. It combines centralized usefulness with owner-controlled data and open-source interoperability; forks remain compatible via a Tangled schema (lexicon). It supports flexible CI options, stacked PRs, and a web of trust. Although alpha, Tangled is posited as a meaningful alternative; try it for new projects.

Arbee chronicles 2026 progress debugging MAME’s Power Macintosh emulation using AI (Claude; GPT‑5.5 via Codex) to generate boot scripts and log data. AI helped locate and fix dozens of issues in PowerPC emulation, PCI Macintosh support, and related devices (Pippin, Power Macintosh 7200/6100). Fixes enabled Pippin startup, PowerPC DRC correctness, native SCSI/boot issues, and booting System 7.5.x to Finder; updated Graphing Calculator FPU flags, with 3D demo now working. Cautions that AI is a tool requiring human supervision and maintainable code over ‘vibe’ results.

Tom's Hardware reports AMD quietly dropped Transparent Secure Memory Encryption (TSME) from consumer Ryzen CPUs after a firmware update, leaving some users vulnerable to physical attacks. TSME encrypts RAM and was extended to lower-end chips, but now appears restricted to Pro/EPYC. AMD has given no official explanation; engineers declined to comment. MSI testing found an AGESA flag enabling TSME on older firmware but not on newer AGESA 1.2.7.0, while Pro CPUs remain supported. The practical impact is unclear, but consumers may lose memory encryption until AMD clarifies.

Apple chief Tim Cook says prices will rise because memory-chip costs have surged, calling the increases unavoidable and the situation unsustainable. He did not specify which products or when, and it was unclear whether the iPhone 18 would be affected. The spike is driven by AI demand and tighter memory supply, with RAM prices more than doubling since Oct 2025; chipmakers like TSMC and Samsung have signaled possible price hikes. Apple has already raised the Mac mini price by about $200, and the iPhone 17 is selling well as Cook set to be replaced by John Ternus in September.

OpenComputer solves regional quota limits by decomposing into deployable "cells"—a control plane plus 5–10 VMs—that can be deployed in AWS, Azure, GCP, or OCI with the same shape. An edge registry (Cloudflare Workers + D1) routes each sandbox creation to the emptiest cell and monitors state via 10-second heartbeats for per-second billing. Boot under 1s, wake 1–2s, hibernate ~6s with S3 checkpoints. Stage progression: Stage 1–4 show growth from 1 region to multiple regions across clouds. Migrating regions alone won’t fix quotas; capacity grows by adding cells and deploying region-wide. Open source at GitHub; try opencomputer.dev.

Describes a mmap trick that maps the same memory into two adjacent virtual regions, creating a “Magic Ring Buffer” that makes writes cross a seam. The author tests this with io_uring registered buffers: builds a Magic Buffer (MgCircularBuffer), registers the buffer’s double extent with the kernel via io_uring_register_buffers, and writes a kdb IPC message across the seam using io_uring_prep_write_fixed to two KDB instances. It works as expected; code and comments are on Github.

Anubis aims to use WebAssembly-based proof-of-work checks for websites, with the check logic defined once and run on both client and server, plus a JavaScript fallback when WASM is disabled. The post then details the author’s quest for reproducible builds of wasm2js, built via wasi-sdk, revealing how identical source bytes can yield different outputs in practice. Factors include __DATE__/__TIME__ stamping, toolchain versions (wasm-opt, clang), WebAssembly exceptions, and architectural differences (x86_64 vs arm64). Workarounds: disable wasm-opt, use fixed flags, disable ASLR, and record per-architecture checksums; LLVM bugs remain.

Local Qwen isn’t inferior to Opus; it’s a different tool built for privacy, control, and cost stability. In a small software business, local models power telemetry analysis, diag tooling, and self-hosted workflows across OpenFaaS, SlicerVM, Inlets, and Actuated. After hardware hurdles (3090s, RTX 6000 Pro), they run Qwen 3.6 27B with llama.cpp on a single RTX 6000 Pro rig, achieving 130–200 tokens/s, guided by tuning and risk of loops. Local models deliver value for specialized tasks (support, testing, end-to-end workflows) but aren’t a drop-in replacement for cloud SOTA on long-horizon unsupervised work.

Follow-up ablation of Gemma 4 (26B) on a 2016 Xeon with 25 flags, 174 runs, each turning off one flag to measure impact. Findings: only a few levers matter on this memory-bound box—flash attention (~2x speed), the physical-core thread count (-t 8 best), and run-time repack for prefill; the drafter helps code but hurts long-context summarization, and a fixed draft length beats autotune for short prompts. Mlock must be kept across reboots; -sm graph and similar flags depend on hardware and can break loads. Throughput saturates around 10–11 tokens/s due to memory bandwidth; next post explores lower quantization.

ACE (AI Compute Extensions) defines x86 extensions to accelerate ML workloads, focusing on matrix-multiplication kernels and reduced-precision formats. It adds matrix-multiply primitives that augment AVX and scalar code with ACE constructs: ACE register state (tile and block-scale registers), data-processing ops that use AVX inputs on tile state, and data-move ops between ACE and AVX registers, plus system-management state. ACE tightly combines AVX vectors with ACE tile registers for high-density tile processing and AVX-style data processing. The AVX10 framework also includes dedicated format-conversion operations.

Brad Feld argues the Rule of 40 can apply to hardware, but you must read the curve, not a snapshot. In SaaS, growth plus profitability is a verdict, but hardware has long development cycles, upfront manufacturing costs, and revenue that trails profitability. Early quarters can look unhealthy even when the business is on track. The test for hardware is the gross-margin trajectory and profitability of each product generation, not a single frame. Formlabs shows hardware trajectory—growth, scale, and margins—while 3D Systems and Stratasys lag. The Rule of 40 remains useful when read as a trajectory, not a snapshot.
