159. Doing Gigabit Ethernet over My British Phone Wires
Disclaimer: None of this is written by AI, I’m still a real person writing my own blog like its 1999 I finally figured out how to do Gigabit Ethernet over my existing phone wires. Powerline adapter and misery I’ve mostly lived with powerline adapters over recent years. Some worked well, some did not (try few and…

162. Joel Spolsky: Painless Software Schedules (2000)
Last October, the Northeast US was plastered with ads for something called Acela, a new express train running from Boston to Washington. With TV ads, billboards, and posters everywhere, you'd think that it would have created some demand for Amtrak's new express service. Well, maybe. Amtrak didn't get a chance to find out. Acela was…

Analysis of more than 40 million alarm-related events shows most alarms offer little operational value, disrupt rest and push crews toward risky workarounds.

165. A Lament for Aperture
I'm an old Mac-head at heart, and I've been using Macs since the mid 1990s (the first Mac I used was an LC II with System 7.1 installed on it). I don't tend to think that the computing experience was better in the olden days — sure, there's a thing to be said about the simplicity of older software, but most of my fondness for those days is nostalgia. An exception to that, however, is Apple's Aperture.

169. An ultra-high-resolution map of (dark) matter
Ordinary matter—including particles such as protons and neutrons—accounts for only about one-sixth of all matter in the Universe. The rest is dark matter, which does not emit or absorb light but plays a fundamental role in galaxy and structure evolution. Because it interacts only through gravity, one of the most direct probes is weak gravitational lensing: the deflection of light from distant galaxies by intervening mass. Here we present an extremely detailed, wide-area weak-lensing mass map covering 0.77° × 0.70°, using high-resolution imaging from the James Webb Space Telescope as part of the COSMOS-Web survey. By measuring the shapes of 129 galaxies per square arcminute—many independently in the F115W and F150W bands—we achieve an angular resolution of $$1.00\pm 0.0{1}^{{\prime} }$$ . Our map has more than twice the resolution of earlier Hubble Space Telescope maps, revealing how dark and luminous matter co-evolve across filaments, clusters and underdensities. It traces mass features out to z ≈ 2, including the most distant structure at z ≈ 1.1. The sensitivity to high-redshift lensing constrains galaxy environments at the peak of cosmic star formation and sets a high-resolution benchmark for testing theories about the nature of dark matter and the formation of large-scale cosmic structure. JWST’s COSMOS-Web survey is used to create an ultra-high-detail dark matter map, revealing hidden filaments, clusters and distant structures. By tracing features out to z = 2, this map shows how dark and luminous matter build the cosmic web across cosmic time.

177. The Home Computer Hybrids: Atari, TI, and the FCC
It’s difficult to say with certainty what the most popular titles or genres were in the early years of computer games. Many of the games were sold directly by mail-order, or through tiny single-proprietor stores, and no software trade organization was collecting comprehensive sales statistics. In 1980, the magazine Softalk began running a list of…

Hi! Long time no see, huh? :) It's been three years since my last State of the Windows article, which was about the inconsistencies in the Windows 11 user experience.
