Atwood's Law predicted JavaScript's dominance through accessibility. A new corollary is emerging: system languages will win through operational efficiency and AI-assisted development.
34. The mountain that weighed the Earth
Suppose you want to find out how much you weigh. It’s easy enough – get a scale, stand on it, and read the number. Now suppose you want to know how much the Earth weighs. You get out a scale and…hmm. What exactly do you do with it? Let’s do a little physics class refresher.…

43. LED lighting undermines visual performance unless supplemented by wider spectra
Life evolved under broad spectrum sunlight, from ultraviolet to infrared (300–2500 nm). This spectrally balanced light sculpted life’s physiology and metabolism. But modern lighting has recently become dominated by restricted spectrum light emitting diodes (350–650 nm LEDs). Absence of longer wavelengths in LEDs and their short wavelength dominance impacts physiology, undermining normal mitochondrial respiration that regulates metabolism, disease and ageing. Mitochondria are light sensitive. The 420–450 nm dominant in LEDs suppresses respiration while deep red/infrared (670–900 nm) increases respiration in aging and some diseases including in blood sugar regulation. Here we supplement LED light with broad spectrum lighting (400–1500 nm+) for 2 weeks and test colour contrast sensitivity. We show significant improvement in this metric that last for 2 months after the supplemental lighting is removed. Mitochondria communicate across the body with systemic impacts following regional light exposure. This likely involves shifting patterns of serum cytokine expression, raising the possibility of wider negative impacts of LEDs on human health particularly, in the elderly or in the clinical environment where individuals are debilitated. Changing the lighting in these environments could be a highly economic route to improved public health.

56. US administration to require app, social media, possibly DNA for travelers
We knew this was coming, but now the clock is running. From Privacy International: "Yesterday the Trump Administration announced a proposed change in policy for travellers to the U.S. It applies to the powers of data collection by the Customs and Border Police (CBP)." "If the proposed changes are adopted after the 60-day consultation, then millions of travellers to the U.S. will be forced to use a U.S. government mobile phone app, submit their social media from the last five years and email addresses used in the last ten years, including of family members. They’re also proposing the collection of DNA." PI linked to and summarized a Federal Register entry describing the proposed requirements: -All visitors must submit ‘their social media from the last 5 years’ -ESTA (Electronic System for Travel Authorization) applications will include ‘high value data fields’, ‘when feasible’ ‘telephone numbers used in the last five years’ -‘email addresses used in the last ten years’ -‘family number telephone numbers (sic) used in the last five years’ -biometrics – face, fingerprint, DNA, and iris -business telephone numbers used in the last five years -business email addresses used in the last ten years. https://www.privacyinternational.org/news-analysis/5713/trump-administration-wants-your-dna-and-social-media The Federal Register entry says comments are encouraged and must be submitted (no later than February 9, 2026) to be assured of consideration.
