Endive: A JVM native WebAssembly runtime

Endive is a JVM-native WebAssembly runtime that runs Wasm with zero native dependencies or JNI, wherever the JVM runs. Born as a fork of Chicory from Dylibso, it aims to be the default, safe, pure‑Java Wasm runtime with seamless Java integration and no native code. Its roadmap includes a pure Java Wasm parser, a simple bytecode interpreter, a build‑time compiler, SIMD, tail calls, exceptions, threading, GC, and multi‑memory, plus API stability (v1.0) and decoupled engines. It’s designed to simplify embedding Wasm in Java apps as an alternative to C/C++ runtimes.

The Lone Lisp Heap

Lone is a Lisp interpreter in freestanding C with no malloc or libc. It evolved from basic C structs to a custom memory model: a naive allocator (first-fit, split/coalesce) and a conservative GC that scans the stack for Lisp pointers. To tame pointers, it rewrote value representation to be index-based into a single heap of values, removing direct pointers. The heap is a flat, page-based array, grown via mmap/remap (mremap) for cheap resizing. Garbage collection still linearly scans blocks to resurrect dead values. The design favors arrays and index math over scattered pointers, enabling relocatability.

Nitpicking the shell history scene in 'Tron: Legacy'

An analytic look at Tron: Legacy’s shell-history screenshot as an educational puzzle. The author argues the scene uses a real Unix session, but with inconsistencies: bin/history instead of the history builtin; uname -a showing SolarOS with Linux-like processes and /proc/meminfo; a configure script unlikely Autoconf; backdoor/root sharing; memory cleanup; a double safety flag for the laser; and odd proportional fonts. He concludes many details are plausible, some are filmmaker mistakes, but the overall depiction is thoughtful and instructive.

About LLMs at Zig Days

Zig Days should be about thoughtful software engineering and hands-on learning, not AI talk; limit LLM discussions, encourage solving problems by hand, deepen understanding of data structures and systems. Acknowledge AI trends but avoid overreliance. For organizers: address AI early, avoid bans, set expectations, foster valuable in-person exchanges, and protect the event's unique community focus.

Just Use Postgres for Durable Workflows

Durable workflows can be built by using Postgres as the orchestrator, eliminating external orchestration. Clients submit workflows to a Postgres workflows table; servers poll and dequeue; as steps execute, they checkpoint to Postgres. If a worker crashes, others recover from checkpoints; Postgres constraints prevent duplicate work. This simplifies architecture, and scalability/availability hinge on the database (horizontal scaling via distributed/Postgres, replication, multi-AZ). Observability is built‑in via SQL queries over checkpoint tables; security is improved by reducing surface area to a single trusted DB. DBOS promotes this approach with Transact libraries and quickstart.

Legislation Killed Would Have Effectively Blocked Police LPR, Including Flock

Amendment 221 to the BUILD America 250 Act would have barred police LPR programs by conditioning Title 23 highway funding on not using LPR cameras for policing, effectively forcing states to choose between federal road money and Flock contracts. It was killed in a May 21, 2026 House markup by a 44-20 vote (Graves and Larsen against; Perry and García as sponsors). Flock lobbying is noted, including Don Andres (a García aide) and firms BGR Government Affairs and Mercury Public Affairs. The piece frames the failure as a sign of rising backlash to LPR.

Hold on for Dear Life

Cory Doctorow argues that cryptography provides real privacy but cannot replace the rule of law. He frames two technopolitical camps: the EFF-aligned view that encryption helps organize resistance to tyranny and protect human rights, and the crypto camp that seeks self‑executing contracts and stateless money. He critiques crypto for being slow, opaque, and dependent on intermediaries, while warning of wrench attacks, reidentification from public ledgers, energy waste, scams, and state coercion risks. Ultimately, crypto is a tool for security and privacy, not a substitute for democratic institutions.

You Were Never Declaring State. You Were Observing by Hand

Old IaC treated state as a pre-declared observation: you wrote HCL or recipes and a blind agent would implement it. That was observing by hand, not declaring state. Now agents can observe reality directly: swamp model methods gather live data and store versioned, schema-validated observations. The @webframp/aws/adopt tool reads AWS resources and brings them under management as data, yielding versioned snapshots. No declaration file is required. Drift is visible by comparing versions. Idempotency moves into workflow logic rather than per-resource code. Benefits: queryability, composition, and drift awareness. The line remains: provisioning/compliance/rollback require intent; other work is observation.

Using Tailscale with an OrbStack VM on macOS

Shows how to use OrbStack on macOS to provision an Ubuntu VM, add it to a Tailscale tailnet, and enable Tailscale SSH. A cloud-init config (dev-server.yml) configures the VM; OrbStack spins a temporary instance to fetch it, then boots the preconfigured VM and enrolls it in tailnet with an auth key. ACLs are defined with a server tag (tag:myservers) and SSH access rules. The process stores the auth key in macOS Keychain (via store-ts-key-keychain.sh) due to sandboxing. Scripts build.sh, run.sh, cleanup.sh automate provisioning, starting, and teardown. After setup, SSH via tailnet or OrbStack proxy.

News about Raspberry Pi 6 and Microcontroller Development – Jeff Geerling

Pi 6 won’t ship before early 2028 due to DRAM shortages; expect faster CPU/IO, with AI compute handled by the CPU, not a dedicated AI chip. Pi Zero 2W is limited by substrate supply; a new vendor will boost capacity, and Pi Zero 3 isn’t imminent due to PCB and RAM costs. The Pi 3 remains popular, selling ~1M units/year. The RP2350 MCU gained a leakage fix in a silicon revision. USB-C for Pico may come later; software remains Pi’s strength, with ~95% of engineering time on software. MCU shipments surpassed SBC sales in 2025, likely widening in 2026.

Trivial Pursuits

David Runciman reviews C. Thi Nguyen's The Score: How to Stop Playing Someone Else’s Game, arguing Nguyen distinguishes between good, voluntary games that foster creative activity and bad gamified systems that extract data and monetize attention. All games score progress, but healthy scoring enables play; bad scoring pretends to have independent meaning and drives power via rankings (universities, etc.). The book’s core tension is the Gap between easy-to-measure metrics and what really matters. Runciman finds the argument overly binary and lacking historical nuance, though he admires the defense of autonomy and variety.
