What Color is Your Function? (2015)

Bob Nystrom riffs on a straw-man language where every function has a color (red=async, blue=sync) and calls must match color. The rigid rules make higher-order functions painful and mirror real-world async programming woes: callbacks, promises, and async-await split code into two worlds, complicating composition. He ties this to JavaScript/Node, Dart, C#, and others, arguing that these pains persist despite modern constructs. Languages like Go (and Lua, Ruby) avoid per-function color by using threads, making concurrency a program-model choice rather than a color-coded constraint.

Sage Care (YC S24) Is Hiring Software Engineers

Sage Care, a YC-backed startup, is building an AI-native operating system for home-care agencies—a CRM and virtual assistant that converts calls and visits into structured care plans, follow-ups, and records. It integrates with WellSky and AxisCare, runs on iOS and desktop, and saves agencies about 100 minutes per intake. They seek a Founding Software Engineer (full-stack) in New York or Miami to shape the tech foundation, own Django app and iOS app, and guide product/tech strategy. 4+ years, Python or iOS, Tailwind; equity, $125k-$250k.

'Incredible' milestone reached as Sweden becomes a smoke-free country

Sweden has reached its target of being smoke-free, with fewer than five percent of Swedes smoking regularly (4.8% in 2025), meeting the 2025 goal. The decline since 2003—down from 16% daily—is attributed to reduced accessibility, higher taxes and prices, advertising bans, and quit-support measures. The rise of snus is noted but not deemed the main cause. Health officials call it an incredible development, though more research on snus’s role is suggested.

Are we self-sovereign PKI yet?

Current PKI for people is custodial and fragile: verification of contact keys is rarely done; email, usernames, and apps depend on trusted platforms or registrars. The piece surveys examples (Signal, iMessage, WhatsApp, Keybase) and shows the gap. It advocates Spaces, a self-sovereign identity layer: names bound to keys with an append-only Merkle trie; root anchored to Bitcoin; off-chain propagation via Certrelay with Merkle proofs; no DNS. The trust anchor is a 32-byte hash, verifiable locally via Veritas against Bitcoin headers; future goal is a zero-knowledge certificate. Key rotation, loss, and adoption remain hard; social/disambiguation unresolved.

The Ballad of TIGIT

TIGIT drugs, buoyed by Keytruda’s success, spurred a multi‑billion, multi‑company race to block the immune checkpoint TIGIT. Roche’s tiragolumab showed promise in phase 2 and triggered a decade of parallel phase 2/3 trials (the SKYSCRAPER program) across cancers. But repeated failures in progression-free and overall survival, plus safety concerns, led to Roche abandoning tiragolumab and Merck discontinuing vibostolimab; others followed. An Fc-silent approach also failed. By 2025-26, the field largely collapsed, with AstraZeneca’s rilvegostomig as the last holdout. The episode illustrates herding in drug discovery.

Germany news: Childfree adults to pay more for elder care

Germany is weighing elder-care reform: a Health Ministry draft would raise contributions from childfree adults to 2.5% of income (employer 1.8%), to fund aging care. Parents would pay lower rates (1.8% for one child, 1.55% for two, 1.3% for three+). All full-time workers over 23 would be affected. DW’s coverage also notes Russia-Ukraine tensions, Pistorius’ Canada trip for submarines, TÜV Süd Brazil dam case, a May heat wave, and calls to modernize police facilities.

Don't Subscribe So Casually

Subscriptions function as ongoing behavioral influences, not just payments. They shape future choices, often more than users intend, a risk amplified by AI services like ChatGPT that tailor and extend engagement. Even valuable subscriptions (insurance, Costco, Apple) shift preferences and spending; the gains come with psychological nudging. Companies design subscriptions for long-term profitability, using A/B testing and alignment with their goals (convenience, loyalty, ecosystem). Consumers are structurally disadvantaged. The remedy: consciously select subscriptions that mirror your values and limits, or treat them as limited purchases to avoid drift.

Stockholm poised to become leading European geospatial intel player

Stockholm is set to become Europe’s leading geospatial intelligence hub after Sweden acquired five Planet Labs Pelican satellites. The move shifts GEOINT power in Europe, potentially giving Sweden more spy satellites than many peers (including France) within a year, but raises concerns about dependence on US technology.

Trying to preserve other peoples code

CRC Generator is a cross‑platform CLI tool (C) that outputs Verilog or VHDL code for CRCs with data width 1–1024 and polynomial width 1–1024. Build: gcc; usage: crc_gen language (verilog/vhdl) data_width poly_width poly_string; poly_string is hex, e.g., 05 for x^5+x^2+1, 8005 for x^16+x^15+x^2+1. Notes that hex form omits the highest-degree term. MIT licensed, authored by Evgeni Stavinov; repository mirrors OutputLogic tool.

Uber president says AI spending is getting 'harder to justify'

Uber says its AI spending isn’t clearly tied to productivity or useful features. Andrew Macdonald says there’s no direct link between token consumption (Claude Code) and better consumer features, despite rising AI metrics. After exhausting its 2026 AI budget early, Uber spent $3.4B on R&D in 2025, up 9% from 2024. CEO Dara Khosrowshahi says AI costs are offset by hiring fewer humans, but the trade-off is harder to justify without demonstrable feature gains.

Opaque Types in Python

Glyph discusses using Python typing.NewType to create opaque data types: keep internal state in a private _RealShipOpts while exposing a public ShippingOptions type via NewType. Expose public constructors (shipFast, shipNormal, shipSlow) and a factory (shippingDetailed) to configure carrier and conveyance. At runtime ShippingOptions is the same as its private base, so no overhead but a private public API surface. This pattern preserves API flexibility and minimizes public churn as configuration options evolve.

A reality check on the AI jobs hysteria

MIT Technology Review finds little evidence of a mass AI-driven jobs apocalypse in the US. BLS data show unemployment is not higher for AI-exposed occupations; only about one in five firms use AI. Stanford/ADP analyses reveal early declines for 22–25-year-olds in highly AI-exposed entry-level roles since 2022, mainly where AI can automate tasks with minimal human input; older workers fare better and wages in exposed sectors have risen. Coding jobs are transforming but not disappearing. The impact remains uncertain; better data and policies are needed to manage a gradual transition.

How do you build a semiconductor company on something that's free?

Daniel Schultz's aesc silicon promotes an open-source silicon model: the core IP is free; value comes from support, customization, and services. Open IP plus inexpensive tools enable many small firms to design custom chips, amplifying demand (Raspberry Pi-like proof). Verifiable security across the supply chain is a key selling point for cryptographic engines. IP Forge could package IP blocks like npm/pip for chip design, accelerating development. Schultz is bootstrapped, betting on a long-term open-source ecosystem rather than rapid VC-backed profits.

Incident with Actions and Pages

GitHub Status reports an incident affecting Actions and Pages. Initial investigations found authentication issues causing Actions runs to fail and downloads to fail, with degraded performance and availability. After a series of updates, the team identified the cause and is actively mitigating. The latest status indicates the degradation has been mitigated and monitoring continues to ensure stability.

Netherlands blocks US takeover of vital digital supplier

The Netherlands blocked US-based Kyndryl’s bid to acquire Solvinity, which runs the DigiD authentication platform used for Dutch public services. The national investment-screening authority advised blocking, citing potential risks to public interest and foreign control. The government upheld an independent screening framework that applies to all investors. The move comes ahead of the EU’s tech-sovereignty package on cloud, chips, and AI. Kyndryl said the decision is politicized and disappointing.
