Academia as a d-index measuring contest

Kevin Munger argues academia is trapped in quantitative metrics, with Impact Factor and Google Scholar h-indices dominating evaluation, but these measures misrepresent reality due to disciplinary differences and co-author inflation. He introduces the k-index, a metric aimed at rewarding output diversity: solo citations, methodological contributions, recency, fractional citations, and interdisciplinarity, with caps to prevent gaming. Using OpenAlex data (political science, since 2000) he advocates open, non-profit publishing over for-profit models. The k-index seeks to de-naturalize metrics and align incentives with true scholarly contribution.

No constitutional right to clean water, federal court finds

A federal appeals court ruled that the U.S. Constitution does not guarantee the right to clean drinking water, upholding the dismissal of a Mississippi residents' suit over Jackson's lead-contaminated water. The plaintiffs argued a Fourteenth Amendment due process right to bodily integrity was violated. Judge Kurt Engelhardt said the lack of clean water, while grievous, does not fit a deeply rooted constitutional right, and there is no right to truthful information from officials during a public health crisis. Remedies include elections, petitions; some states protect safe water, but not federally.

If a Tesla Cybercab fleet were profitable, Tesla wouldn't sell you one

Electrek argues that a profitable Tesla Cybercab fleet is unlikely and the offer serves to offload risk. Past promises of robotaxi income (Autonomy Day 2019) never materialized; owners paid for FSD with nothing to show. MisterGreen, a Dutch lessee, bought 4,000 Teslas hoping for robotaxi revenue, but Tesla slashed prices and these Teslas depreciated; MisterGreen went bankrupt. Tesla owns the network, software, and pricing and would keep earnings if profitable, so selling you a Cybercab only shifts capex and depreciation onto buyers while Tesla profits from software and control.

Bill Gates tries to install MovieMaker

Bill Gates complains that Windows Usability is regressing, recounting a painful attempt to download Movie Maker: slow Microsoft.com pages, confusing search terms, detours through Windows Update, a lengthy install, unwanted reboots, and a bloated, broken program list. The thread shows a leadership scramble to fix the web/download experience, with proposals to appoint one owner (likely Dave’s team) to coordinate across WU and MS.COM, and to improve discoverability and promotion of MM2/WMP9S, arguing marketing should not own releases. Overall, it highlights urgent usability and process problems.

Decoding the NEC V20 Microcode

A deep dive into decoding the NEC V20 microcode to enable cycle-accurate emulation in MartyPC. The author photographed a V20 die and analyzed its ROMs: 29,928 bits (1032 29-bit words) in a 258×116 array; a metal-layer switch allows V20/V30 to share the mask, explaining the word-count quirk. Because metal obscured bits, he mapped bit locations with MaskRomTool, exported coordinates, and trained a PyTorch CNN on a 105 MB image set to classify bits as 0/1, manually labeling ~1,000 bits to bootstrap. The result: decoded microcode words and a path to emulation; collaboration with Vintage Computer Federation; artifacts on GitHub.

The Dataflow Model Revisited

On the VLDB Test of Time, the authors re-evaluate “The Dataflow Model” after 11 years, finding its core ideas—event-time primacy, incompleteness, and strong consistency—largely sound. They critique missteps: overemphasis on windowing/triggers, over-engineered triggers, and treating streaming separately from tables. The path toward SQL, incremental maintenance, and materialized views with freshness contracts better serves analytics. Completeness splits into watermarks (visible streams) and snapshot-consistent refresh. Batch vs. streaming is mostly semantic; low-latency demand aligns with OLTP/OLAP, and streaming may fade as analytics converge.

Whistle Synth

Whistle Synth, Jeff Kaufman’s whistle-controlled synthesizer, is now in the Mac App Store. Free, ad-free, and open source. Requires an external mic (headphones reduce latency). Claude AI helped cut round-trip latency from ~80 ms to 5 ms and split logic into a detector and a synth to fix stutters. It features voices including an octaveless bass and a drawbar Hammond-like treble organ, plus a fifth-down setting for easier key matching. App-store distribution involved icon design and demo video with Claude; AI collaboration enabled faster completion.

Simple Is Not Small

An essay arguing that simplicity, not merely small size, is the goal of good software. It shows Unix pipelines as small but tightly coupled, contrasts them with large apps that feel simple yet are complex, and uses Rich Hickey’s “Simple Made Easy” braid metaphor to critique coupling. It explains how data representations can be decoupled from type checking (Clojure vs Rust) and argues to always strive for simplicity. Practical guidance includes building strong mental models, good taste, possibly writing the hard parts, and favoring decoupled declarative specs and gradual decoupling to create maintainable systems.

De-Brainrot Vacations

Daniel reflects on brain fog and a slower learning pace since starting as a Software Engineer, worsened by AI and doomscrolling. He describes a de-brainrot vacation: slow pace, time in nature with family, board games with nephews, plus new habits like handwriting, side projects, and blogging. He read SPQR and De Newton a Einstein y algo más, then Fitzgerald and Atomic Habits, and discovered a maths/physics hobby, studying calculus proofs and textbooks online. He aims to regain deep learning ability, understand advanced physics, and read new papers, while noting career uncertainty in AI.

Tiny $70 Xteink X3 e-reader puts Silicon Valley to shame

Saahil Desai extols the Xteink X3, a $69/70 credit-card–sized e-reader, as the single best tech purchase in years. Despite humble hardware—no touchscreen, color display, or backlight—the device makes reading addictive, fitting on a phone and encouraging on-the-go reading, reducing phone time. Its tiny display forces quick pages, boosting engagement with books like The Power Broker. Though limited (no cover art, clunky software), it spawned a viral DIY ecosystem: Crosspoint firmware, Libby access, and accessories. It signals a market return to cheap, simple, customizable gadgets from China.

Smartphone makers don't bother to comply with EU repairability requirements

One year into the EU's repairability rules, Right to Repair Europe says over 80% of smartphones/tablets still lack required repair information. Of 2,334 models, only about 18% list a site with spare-parts prices or repair instructions; many records are blank or point to non-relevant pages, with some directing to Temu/AliExpress. Some brands still award themselves top repairability scores despite non-compliance. Enforcement appears weak: scores are self-declared and not consistently published on labels. They call for full documentation behind scores and easier reporting of non-compliance. From February next year, new devices must have user-replaceable batteries.

I Connected My Withings Body+ to Home Assistant with an ESP32

Author connected Withings Body+ to Home Assistant directly using an ESP32 and ESPHome, bypassing the Withings cloud. They removed Wi‑Fi from the scale so data stays local. Using an original ESP32 (Bluetooth Classic), the scale sends measurements to ESP32 via Bluetooth; ESPHome forwards to Home Assistant over Wi‑Fi. They reverse‑engineered the protocol with Codex/OpenCode, building a custom ESPHome component that handles two user profiles by using the scale's user IDs. They added template sensors so last measurements persist across restarts. Result: local, real‑time dashboards; not universal for other scales; code not yet uploaded.
