Dan Luu explains why he spots hundreds to thousands of bugs weekly while most people see none: they're hitting the same issues but not noticing. He argues that curing this 'bug blindness' is crucial for programmers, sharing examples from search engines to Blackboard and Discourse. He also reflects on how fans of a product or company often ignore its flaws, a blindness he claims to be less prone to.

FreeCORE is an independent continuation of TrueNAS CORE, now at version 15.0-RELEASE. It allows existing TrueNAS CORE 13.3 systems to upgrade in place and continue receiving updates. The project is based on FreeBSD and OpenZFS, with source code available on Codeberg and GitHub.

Hy4 preview is now available for developers and researchers to explore, marking a significant step in Tencent's AI strategy.

CPython has added RISC-V as a tier 3 supported platform, marking a significant milestone for the open-source instruction set architecture. The announcement, made by a CPython developer, highlights the growing importance of RISC-V, whose ecosystem is projected to quadruple by 2032. The support was made possible through community contributions and testing on real hardware, with key assistance from the RISE Project, which provided buildbots and debugging support. Future plans include integrating RISC-V into CI, promoting to tier 2, and exploring architecture-specific optimizations.

Tether, an open-source project by Zack Bartel, brings Apple's Continuity features to Linux, including iMessage, SMS, notifications, clipboard sync, file transfer, and OTP autofill. It uses Bluetooth to communicate with an iPhone, avoiding the need for a Mac proxy. The project is MIT-licensed and aims to be a complete solution for Linux users with iPhones.

NASA's Nancy Grace Roman Space Telescope, named after the agency's first chief astronomer, is scheduled to launch on August 30, 2026. With a field of view at least 100 times larger than Hubble's, it will survey a billion galaxies to investigate dark energy, dark matter, and exoplanets, and directly image exoplanets and planet-forming disks.

A $1 fee added to Texas auto insurance policies in 2023 to fight catalytic converter theft has quietly funded at least 3,200 Flock license plate readers across the state, according to a Texas Tribune analysis. The Motor Vehicle Crime Prevention Authority, overseen by Greg Abbott appointees, funneled over $30 million into the surveillance network, which can track vehicles nationwide without warrants. After the Tribune's findings, Abbott paused state funding for the cameras, but the program has already sparked privacy concerns and legislative backlash.

Defragger is a real graphical disk defragmenter for Linux, written in Rust and Qt Quick/Kirigami. It provides a visual block map that shows how files, free space, and metadata are allocated, making the filesystem legible. It can analyze fragmentation, defragment ext4 files online, and compact offline FAT16/FAT32 volumes. The GUI and CLI run unprivileged, with privileged operations handled by a PolicyKit-authorized helper. It's alpha software, but offers a safe demo with a temporary loop device. Perfect for those nostalgic for Windows' defrag tool or needing reproducible storage layouts.

Starting a new job often triggers an urge to prove yourself by making an immediate impact. But action without context is just noise. Drawing on his move from Monzo to Engine by Starling, the author outlines a three-phase approach: a collection period focused on active listening and mapping the terrain, a synthesis phase to connect dots and categorize opportunities, and strategic acceleration with small public wins and shared hypotheses. The key is to shift from 90% listening to 80% doing only after building a foundation of context.

LLMs excel in greenfield projects but stumble on legacy codebases where ambiguity and missing shared language cause them to guess wrong. The author argues the fix isn't upgrading the model but preparing the code. He combines Domain-Driven Design with AI agents: a `.workflow.json` manifest and `CONTEXT.md` glossaries define bounded contexts and ubiquitous language, while a generator produces a context map and detects disagreements between declarations. Strategic decisions remain human; tactical implementation is delegated to agents via skills and sub-agents, turning issues into PRs for review. This approach makes the codebase answer the questions models previously guessed at.

SQLite's JSON support, combined with generated columns, lets you treat it as a document database. This post shows how to insert JSON, extract fields into virtual columns, enforce constraints, and index them—all in an embedded database. It's ideal for lightweight apps and webhooks, allowing flexible schemas without a separate document store.

This paper explores how Rust's type system can model state machines, using typestate and newtype patterns to enforce protocol correctness at compile time. It demonstrates encoding states as types and transitions as methods, preventing invalid operations and reducing runtime errors. The approach leverages Rust's zero-cost abstractions, offering a robust alternative to runtime checks for domain logic.

Python's signal handling model defers user handlers until the interpreter is safe, but reentrancy can still bite: if a signal arrives mid-print, the handler may call print again, triggering a RuntimeError. This article stress-tests the scenario, explains why it happens, and argues it's a curiosity rather than a practical threat—though it still advises against heavy work in handlers.

Glacier mice are fuzzy green balls of moss that live on glaciers and move in coordinated herds, puzzling researchers. Found from Alaska to Uganda, these colonies host tiny creatures like water bears and springtails. Their movement, averaging 2.5 cm per day, appears non-random and may result from the sun melting ice unevenly around them. They can persist for six years or more, thriving in an ecosystem that seems inhospitable.

EVE Online has started the massive migration of its 2.4 million-line Python 2 codebase to Python 3, a process that will take years. The first stage, already deployed to Tranquility, uses automated tools to make code compatible with both versions. Future stages will require careful manual review of ~20,000 lines that behave differently in Python 3. The goal is a faster, more maintainable game, with no noticeable changes for players.

The Trump administration has been using an obscure customs provision, 19 USC 1509, to obtain private records of journalists, nonprofits, and unions without judicial oversight. In one case, the DHS obtained six months of phone records for Minneapolis journalist Georgia Fort, including over 10,000 calls and texts, without notifying her. The agency also served Google with a summons for YouTube account information on Fort, Don Lemon, and others, bypassing a judge who had previously rejected a warrant request. Experts call the tactic an outrageous abuse of power, while the administration argues it has broad investigative authority under the statute.

An engineering leader argues that while AI tools dominate the productivity conversation, the real multiplier is a strong team culture. Drawing on 13+ years in the industry, he explains how bad culture undermines even the best AI adoption, why AI amplifies existing strengths and weaknesses, and why forcing AI top-down backfires. He offers practical questions to assess your culture and a checklist for building an environment where great people thrive—then let AI multiply their impact.

At Hot Chips 2026, Samsung detailed its Processing-in-Memory (PIM) implementation in LPDDR5X DRAM, placing MAC units inside each of the chip's 16 banks to exploit internal bandwidth. This yields 614 GB/s, eight times the standard 76.8 GB/s, and up to 2.4 TOPS per chip. While it works with standard memory controllers via special row addresses, the design forces software into a corner: PIM mode disables caching, prefetching, and out-of-order execution, and complicates multitasking. The article explores these challenges and suggests hardware changes to make in-memory compute practical.

Defrag98 is a free, browser-based simulator of the classic Windows 98 Disk Defragmenter. It recreates the iconic grid of colored clusters, complete with authentic hard-disk sound effects, and lets you choose from four virtual drives with varying speeds. It's pure nostalgia—no real files are touched, and it works offline as an installable web app.

Scientists recorded the highest ocean temperature ever measured on Aug. 22, when the global average sea-surface temperature reached 70°F, according to Europe's Copernicus agency. The previous record was set in March 2024. The heat combines decades of human-driven warming with a powerful El Niño in the tropical Pacific, raising risks to marine ecosystems, coastal communities, and extreme weather.

Martin Uecker explores a hack to support nested functions on older GCC versions without requiring an executable stack. By extracting the code address and static chain from the trampoline that GCC generates, and using `__builtin_call_with_static_chain`, the trampoline can be bypassed, allowing the stack to be cleared with `patchelf --clear-execstack`. He also proposes using trampolines as function descriptors, interpreting them at call sites. Implemented in his experimental library noplate.

vphone-cli is an open-source tool that boots a virtual iPhone on Apple Silicon Macs using Apple's Virtualization.framework. It automates the entire process—downloading and patching IPSWs, performing DFU restores, and installing custom firmware—with a single command. Five firmware variants offer increasing levels of security bypass, from patchless to full jailbreak with Sileo and TrollStore. The project also includes a control socket for AI-driven UI testing via MCP.

A newly discovered Windows backdoor, SLEEPWALKER, hides inside a fake ESET Management Agent DLL and waits passively for a single crafted network packet before executing any code. It carries no payload and contacts no C2 server; instead, it sniffs traffic for a magic trigger, then decrypts and runs a program written in a custom 23-instruction bytecode language. The implant supports scheduling, staged file delivery, in-memory execution, and multiple covert transports including DNS and VMware's VMCI channel. Its design makes it nearly invisible on the network, but its implementation has weaknesses, suggesting it may be an early version.

Colorado's Front Range cities face harsh growing conditions—hot summers, cold winters, low rainfall, and alkaline soils—that are worsening with climate change. To build a resilient urban forest, experts recommend diversifying tree species beyond the vulnerable ash and cottonwood, looking to southern seed sources for heat and drought tolerance, and embracing native oaks and other tough trees. This article interviews four tree experts who share their top picks and strategies for adapting our urban canopy.

This article explores how colors can be quantified physically, moving beyond imprecise word labels. It explains spectral power distributions, photoreceptor cells, and the science behind color perception, including why hex codes are limited and why color blindness occurs.

After six years of looping the same YouTube video for FFXIV's aetheryte crystal ambience, one engineer finally extracted the actual game audio and built a seamless web player. Using XIVLauncher's SoundFilter plugin to identify the exact asset, he recreated the experience with the Web Audio API—looping the hum perfectly and randomly scheduling whir sounds with randomized pitch and volume, just like in the game. The result is a gapless, resource-light ambience generator that runs in the browser.

Ashley from Construct explains practical techniques for recovering data from corrupt ZIP files, covering common causes of corruption, diagnostic steps, and manual repair methods using standard tools and hex editing. The guide emphasizes that not all corruption is fatal and offers a systematic approach to salvage as much data as possible.

Typebase is a developer tool that turns your backend into a single folder of TypeScript files. Define your database schema, server actions, and auth in a `typebase/` folder inside your app. One command deploys a fully typed server that your frontend calls like local functions. It offers end-to-end type safety, explicit authorization, and supports deployment to Vercel, Cloudflare Workers, or Deno Deploy with Postgres on Neon. With no vendor lock-in and idiomatic clients for Next.js, SvelteKit, Nuxt, and Expo, Typebase combines the DX of Convex with the openness of Supabase.

StemDeck is a free, open-source desktop app that splits any song into six stems—vocals, drums, bass, guitar, piano, and other—using Meta AI's Demucs model. It runs entirely on your machine, so your audio never leaves your computer. No account, no subscription, no uploads. You can drop in an MP3, WAV, or FLAC, or paste a YouTube URL, then mix stems in a DAW-style editor with mute, solo, volume, and waveform zoom. Export individual stems or a custom mix. Built with Python, FastAPI, and Tauri, it's a privacy-friendly alternative to cloud services like Moises and LALAL.AI.

In a candid essay, one of Burning Man's three founders reflects on the festival's evolution from a small anarchist gathering in the Nevada desert to a global phenomenon. Though he hasn't attended since 1996, he's watched from afar as the event he helped create became something unrecognizable—a loss of its original punk-industrial spirit and anarchist ethos that he finds deeply saddening.
