Valve open-source the Steam Machine e-ink screen so you can make your own

Valve has open-sourced its “Inkterface” e-ink display project for the Steam Machine under an MIT license, providing design files, a parts list, and an assembly video on GitLab. This allows anyone to build their own front-plate e-ink display. Third-party accessory maker JSAUX has indicated plans to produce pre-built versions.

Startup targets datacenters with 3D-printed nuclear reactor module

A startup has introduced a 3D-printed thorium microreactor aimed at datacenters, offering up to 30 MWe of power for as long as 30 years. The modular design targets the energy demands of large-scale computing facilities.

Until_Heat_Death_Do_Us_Part: Broadcasting heat death counter every sec over 100Mbps ethernet

An ASIC with a 383-bit counter increments every 20 nanoseconds and broadcasts the current value via 100Mbps Ethernet every second, theoretically counting until the heat death of the universe (~10^100 years), with a hidden easter egg on overflow. However, the accompanying software only parses 64 bits, limiting correct operation to 11,680 years.

Blackstone’s QTS has scrapped plans to build its portion of a 2,100-acre data center campus in Virginia’s Prince William County, following years of opposition and legal challenges from residents. The proposed development, located near a historic Civil War battlefield, had been stalled by lawsuits.

💻 Software & Performance

Rust Coreutils cp Ended Up Breaking Ubuntu Image Builds with Incompatibility

A bug in Rust Coreutils’ cp command, specifically its handling of the -L argument, caused Ubuntu live media ISO builds to fail. Ubuntu reverted to the GNU Coreutils version of cp as a fix. A patch has been proposed upstream but has not yet been merged.

60% Fable cost cut by converting code to images and having the model OCR it

pxpipe is a local proxy that reduces Claude Code’s input token usage by converting bulky text (system prompts, tool docs, history) into compact PNG images, exploiting the fixed token cost of images. This achieves an input-token reduction from roughly 25k text tokens to ~2.7k image tokens in a real example, translating to a 59–70% lower end-to-end bill. The tool is workload-dependent and occasionally has format compliance issues on first replies.

P vs NP and Market Competition

A new proof shows competitive markets require P ≠ NP, as tractable collusion detection under P = NP would enable sustainable collusion, while intractable detection makes collusion unstable. Combined with prior work showing market efficiency requires P = NP, this creates a fundamental impossibility: markets cannot be both informationally efficient and competitive. Advances in artificial intelligence are shifting markets from competitiveness toward algorithmic collusion by expanding computational capabilities.

Jamesob’s guide to running SOTA LLMs locally

The article outlines two tiers for running state-of-the-art LLMs locally: a ~$2k setup with two RTX 3090s (48GB VRAM) for models like Qwen3.6-27B, and a ~$40k setup with four RTX Pro 6000s (384GB VRAM) for models like GLM-5.2-594B. The author details their personal high-end rig, which uses PCIe Gen4 switches for direct GPU communication and a last-gen DDR4 system to prioritize VRAM spending.

Anatomy of Persistent Memory’s 3 Layers: Comparing ContextNest, Mem0 and Zep

Production-grade AI agents require a three-tier persistent memory architecture combining conversational session context (Zep), user personalization (Mem0), and governed corporate knowledge (ContextNest) to avoid retrieval of stale or conflicting facts. A single memory database is insufficient; deterministic context governance is essential for ensuring agents act only on verified, version-controlled organizational truth.

PostgreSQL and the OOM killer: Why we use strict memory overcommit

Strict memory overcommit protects PostgreSQL from catastrophic OOM kills by preventing the kernel from terminating backends, which could corrupt shared memory and require full crash recovery. However, a three-character kernel bug once forced the team to temporarily disable this setting. The article also outlines a heuristic for determining the appropriate memory overcommit limit.

Program-as-Weights: A Programming Paradigm for Fuzzy Functions

Program-as-Weights (PAW) compiles natural-language specifications into compact, locally-executable neural artifacts using a 4B compiler trained on the FuzzyBench dataset. A 0.6B interpreter running PAW programs matches the performance of direct prompting with Qwen3-32B while using roughly one-fiftieth the inference memory and achieving 30 tokens/s on a MacBook M3. PAW reframes the foundation model from a per-input solver into a tool builder that produces reusable, low-cost artifacts for offline use.

A Road to Common Lisp (2018)

The article serves as a personal guide to learning Common Lisp, emphasizing the importance of understanding its history. It traces Lisp from its creation in the 1950s through various dialects to the 1995 ANSI standard, which remains the current specification. The author shares their own learning path but notes that this is just one approach among many.

Pandoc Lua Filters

Pandoc Lua filters, introduced in version 2.0, run within the pandoc executable using a built-in Lua interpreter, eliminating the need for external dependencies and JSON marshaling overhead. They are defined as Lua tables or functions corresponding to AST elements and applied via the --lua-filter option, offering performance comparable to pandoc without filters.

Commodore 64 Basic for PostgreSQL

PL/CBMBASIC is a PostgreSQL extension that executes Commodore 64 BASIC V2 code inside the database, using a C-based emulation of the original 6502 interpreter for very fast per-row performance. Functions require mandatory line numbers, have reserved keywords that trigger errors at creation time, and can interact with the database via BASIC’s OPEN/INPUT#/PRINT# commands by treating SQL statements as device 8.

14× faster embeddings: how we rebuilt the ONNX path in Manticore

Manticore Search’s new ONNX Runtime backend in version 27.1.5 delivers approximately 14× faster embedding throughput than the previous SentenceTransformers/Candle path, increasing average performance from 5–11 docs/sec to 70–230 docs/sec. The speedup comes from reworking model execution—specifically disabling intra_op_spinning and eliminating in-worker document batching—with no user-facing API changes required.

The Safari MCP server for web developers

The Safari MCP server, introduced in Safari Technology Preview 247, connects agents to a Safari browser window, granting access to the DOM, network requests, screenshots, and console output for autonomous debugging. It streamlines web development by reducing window hopping and enabling agents to handle tasks like compatibility checks, performance analysis, and accessibility testing directly from the terminal.

Why implementing ActivityPub is hard, and why it doesn’t have to be

Implementing ActivityPub is difficult due to multiple competing HTTP signature standards (e.g., draft-cavage vs. RFC 9421) requiring “double-knocking” and the flexibility of JSON-LD allowing many document shapes. The author developed Fedify, a framework that handles these complexities so developers no longer need to implement everything from scratch.

The mask that compiles to nothing: how HotSpot’s JIT learned to reason about bits

HotSpot’s C2 JIT compiler optimizes bitwise expressions like (x << 2) & -4 by tracking “known bits” (definite zeros and ones) alongside value ranges. For x << 2, the compiler knows the bottom two bits are zero, making the subsequent AND with -4 redundant and eliminable. This approach, similar to LLVM’s KnownBits, enables reasoning about bit-level properties beyond simple range constraints.

Fixing full-bleed CSS

The article highlights that the common full-bleed CSS technique using 100vw can cause alignment issues on Windows due to scrollbar width. It proposes modern fixes using CSS container queries with cqi units and @property for nested containers, while also noting future proposals for directly referencing containers in container units.

The Free Market Lie: Why Switzerland Has 25 Gbit Internet and America Doesn’t

Switzerland achieves fast, affordable internet by treating fiber as a natural monopoly—building shared, neutral infrastructure that multiple providers compete over. In contrast, the United States and Germany allow redundant overbuilding of separate networks, wasting resources and resulting in slower, often monopolistic service.

Peter Thiel in Aspen: The pope is ‘working for the Chinese Communists’

Billionaire investor Peter Thiel accused Pope Leo XIV of inadvertently acting as a “Chinese communist agent” by calling for AI regulation, arguing it would slow the U.S. in the AI race against China. He also warned of a “democratic-socialist takeover” of the Democratic Party and criticized Western institutions. Thiel made the remarks during a nonrecorded Aspen Ideas Festival panel with Francis Fukuyama.

An American Privacy Emergency

On June 4, 2026, the U.S. Commerce Department issued a directive banning modern disclosure avoidance techniques such as differential privacy for Census Bureau and BEA data, reverting to outdated coarsening and suppression methods. The order, driven by political motives and bypassing standard procedures, undermines both data utility and legally mandated confidentiality protections. It fulfills promises from Project 2025 and the Center for Renewing America, which opposes differential privacy as an obstacle to identifying individuals’ citizenship status.

Instagram ran ads in India promoting child sexual abuse material, linking to Telegram channels

A BBC investigation found paid Instagram ads in India promoting child sexual abuse material, using terms like “rape video” and linking to Telegram channels where content was sold for as little as 99 rupees.

Bezos’ evolving Trump ties boost his firms’ federal contracts in second term

Jeff Bezos has shifted from being a target of President Trump’s animosity in his first term to a close ally during the second, resulting in rapid growth for his space company through increased federal contracts. Trump once asked aides to break up Amazon, calling Bezos a “son of a bitch,” but now Bezos laughs heartily at Trump’s speeches as his business benefits.

Twenty-five years ago, Bram Cohen launched BitTorrent, a peer-to-peer file-sharing app that used swarming distribution and lacked built-in search, allowing it to evade the legal shutdowns that befell Napster and Kazaa. The protocol quickly dominated internet traffic, driving massive media piracy while third-party sites and the protocol itself thrived despite industry opposition. Cohen, whose goal was a revolution rather than a business, created a tool that still attracts tens of millions of monthly users today.
