Reverse engineering my ADHD test

Veritas details taking an online ADHD test that felt like a Flash game, then reverse-engineering its client-side code to reveal how four metrics—Attentiveness, Timeliness, Impulsiveness, Hyper-Reactivity—are scored. They find the test tracks every spacebar press, focus shifts, and even switches assets by age group. A vulnerability in a send_parent_report API lets them experiment by running a spam test, a serious test, and a friend’s test. Spam results show low credibility; the serious test aligns more with norms. A psychiatrist follow-up confirms ADHD with high impulsiveness, prompting personal reflections.

Tmp.0ut, Vol. 5

tmpout is a 2026 issue/mixtape-style zine listing 20+ articles on Linux ELF hacking and reverse engineering. It includes an intro, an interview with Doug McIlroy, deep dives into 57- and 440-byte ELF viruses, metamorphic and polyglot ELF techniques, ROP/Brainfuck tooling, kernel loading and ASLR, syscall hooks, code virtualization, self-extracting/loading ELF workflows, a recap, and a mixtape.

No country for mediocre mathematicians

garvy wrestles with being a “mediocre” mathematician in a hyper-competitive era, detailing career doubts, mentorship under Jeremy, and the mix of passion, ego, and fear in math. He reflects on AI’s rising role—provoking awe and unease—sharing how Claude Opus accelerates work and reshapes literature searches, revealing AI’s potential to outperform humans in parts of research. He champions small, incremental contributions alongside big leaps and questions what counts as mathematics. Ultimately, math is about pursuing understanding amid frustration and dogma.

You Rename My Lake – I Move My Hosting

Olaf Alders describes moving PrettyGoodPing hosting from DigitalOcean in the US to Hetzner in the EU, citing price and other reasons, with a similar cutover planned for MetaCPAN. He’s also working to de-Google his life, adding email login as a fallback to Google login. The post ties in related naming controversies and notes the move isn’t sponsorship-driven; it’s about reclaiming control over hosting and dependencies.

Dwarf Fortress is getting the mother of all magic updates

Dwarf Fortress is getting the Myth and Magic update, expanding magic to the fundamental cosmological makeup of the universe. It will let fortresses pursue magical research as discovery, adding magic materials, enchantments, rituals, ruins and spells that can explode or alter the world. World generation will produce various wizardries as the landscape is laid out. A goblin-shredding hex that shifts stone is shown in the trailer. The update is due later this year.

Konrad Zuse Museum shutting down due to lack of funding

The Zuse Computer Museum ZCOM in Hoyerswerda could close at year’s end after the municipal housing company cut its premises subsidy, with the city council weighing continued funding. Without subsidies, the ZCOM Foundation would have to shut down. Opened in 2017 after a 2013 closure, ZCOM houses Konrad Zuse computers (Z11, Z22, Z22r, Z23, Z25), Robotron exhibits from the GDR era, and information on Nikolaus Lehmann; attendance is about 10,000 annually, below the planned 20,000–25,000.

You probably own this 7-Eleven (and that's why it looks so sad)

Lawler argues the U.S. built environment is shaped by money and law, not place-making. Highly liquid land ownership via REITs and triple-net leases makes properties like a Williamsburg 7-Eleven interchangeable, owned by distant investors (including Vanguard) who rarely care about local charm. Zoning, tax rules, and capital-stack finance push development toward large, single-use, car-centric sites (edge cities like Tysons) rather than mixed-use neighborhoods. The result: beloved, walkable places are replaced by commodified, low-charisma blocks. The piece calls for patient, traditional-neighborhood investment and policy shifts toward place-based, long-term stewardship.

Agents still can't automate Excel

AI agents have improved at editing Excel but struggle to evaluate workbooks, especially when Excel isn't installed in cloud sandboxes. In such cases, agents may fall back to shadow analysis via Python, which can yield results that don't reflect the workbook’s actual calculations. LibreOffice can serve as a workaround, but compatibility gaps exist, and some sessions still use hidden Python calculations. Orcaset advocates a different route: building models in pure Python for full traceability, deterministic results, and scalable automation without Excel or third-party apps.

Marx, Keynes, and A.I

John Ganz discusses a paper on “The AI Layoff Trap” showing rapid automation creates a demand externality: firms save on labor yet collectively depress consumer demand, sparking an AI adoption arms race. Individually rational, this coercive competition harms workers and firms, echoing Marx’s critique of capitalism and Keynes’s warnings about wage cuts reducing demand; Crotty’s idea of competitively coerced investment helps explain it. Remedies include a Pigouvian automation tax and coordinated investment, plus a public debate on how to deploy AI, recognizing AI as a common good rather than private property.

ravynOS: Pre-alpha open-source OS based on Darwin, FreeBSD, Apple open-source

ravynOS is an early-stage, pre-alpha open-source OS based on Darwin, FreeBSD, and Apple code, designed to be macOS-app compatible with no hardware restrictions. It's a developer preview, not ready for end users. Goals include a macOS-like finesse with open-source freedom: clean design, global menus, standard Command-key shortcuts, drag-and-drop installs, familiar folder hierarchy, native Cocoa APIs, and handy terminal tools. Community involvement via Discord, Wiki, forums, GitHub; project run by RavynSoft (2021–2026).

I Turned My Security Cameras into an Automatic Bird Identification System

An IT tinkerer uses three existing security cameras with microphones and BirdNet-Go running in Docker on local hardware (no cloud) to create a real-time bird (and bats, frogs) identification system. It streams from RTSP cameras, runs multi-model local AI (including Google Perch v2, expanding to 14,795 species), and continuously analyzes audio to identify species as they sing. It supports alert rules with instant notifications (e.g., to a Discord channel), novelty tracking for new detections, and data sharing via BirdWeather. It integrates with Home Assistant (MQTT). Self-hosted, private, no subscription; hobby-friendly on Raspberry Pi.

German Konrad Zuse Museum shutting down due to lack of funding

Das Konrad-Zuse-Museum Hoyerswerda muss schließen, weil die Finanzierung einbricht. Der jährliche Bedarf von rund 0,5 Mio. Euro wurde durch gekürzte Zuschüsse nicht gedeckt; ein anonymes Spendenangebot von 250.000 Euro kam mit Bedingungen (Standort erhalten, Konzept modernisieren) und das Kulturministerium lehnte weitere Mittel ab. Bis Jahresende wird die Ausstellung abgebaut; rund 18.000 Geräte und 6.000 Bände gehen in Depots. Befürworter mahnen, es sei ein Bildungsort verloren, kein reines Erlebnismuseum.

Mental Health Workers Say Algorithmic Triage Is Hurting Patients

An HTTP 403 Forbidden error from an Nginx server, indicating access is denied.

My Experience Has Nuance, Yours Is a Data Point

Eric Bailey’s examples argue for richer feedback than a few icons to express the nuance of media experiences. The post echoes the familiar gap: I’m clicking ‘thumbs up’ but don’t mean what the metric implies, or I hatewatch. Bryan Cantrill adds the need for a button to signal self-loathing or rage clicking. We often treat these signals as objective data and redesign catalogs accordingly, forgetting individual nuance. The piece calls for conversations about values, nuance, and vision—asking what messages data actually carry and warning that introspection on what users mean is slow and overlooked.

Launch HN: Hebbian Robotics (YC S26) – Build scalable robotics data pipelines

Hebbian Robotics' HFlow is an open-source SDK for scalable multimodal data pipelines in robotics and physical AI. It enables teams to build, validate, and provenance-track data for AI training by processing MCAP episodes (video, state, actions, metadata) through a four-stage lifecycle: collection, ingestion, curation, delivery. Pipelines render as graphs; provenance and quality evidence are stored in a Parquet catalog and queried with DuckDB. It runs locally (Docker Compose) or via an Airflow-based runtime, designed for small teams, under Apache-2.0 license, with community involvement.

C++26: Standard Library Hardening Experiments

C++26 adds hardened standard-library implementations where selected preconditions are hardened and violations terminate instead of UB. Hardened mode is implementation-defined and vendor-controlled (GCC: _GLIBCXX_ASSERTIONS with -fhardened; Clang: _LIBCPP_HARDENING_MODE FAST/EXTENSIVE/DEBUG; MSVC: _MSVC_STL_HARDENING). Affected areas include vector[] access, front/back, optional, span, string, iterators, and more. Violations follow C++26 contracts (P3471, P3697, P3878) with terminating semantics. Runtime checks can occur even in optimized builds; not a full memory-safety guarantee or sanitizer substitute, but a standardized baseline for detectable failures.

Launch HN: Almanac (YC S26) – AI that knows your company

Almanac is an always-on agent with its own computer that signs into your tools, watches activity, and keeps a live, source-linked company wiki. It reads Gmail/Slack/Granola, files bugs with repro steps, drafts notes and renewal decks, and then acts across tools to get work done, reporting completion. Pages update automatically (pricing, QBRs, CSV issues). It can read/edit the wiki, revoke connections, and shares only decisions in the wiki. It doesn’t replace tools; it augments them and runs even when your laptop is closed.
