Einstein and his peers were ‘irrationally resistant’ to black holes
1 day ago By Ben Platts-Mills, In a special illustrated feature, Ben Platts-Mills explains why Albert Einstein and other eminent physicists refused to believe black holes could be real. Were they too strange and sublime to imagine? All stars must eventually die, but when they do, they enter an afterlife. A smaller body, like our Sun, […]
CPS in Hoot
Good morning good morning! Today I have another article on the Hoot Scheme-to-Wasm compiler, this time on Hoot’s use of the continuation-passing-style (CPS) transformation. calls calls calls So, just a bit of context to start out: Hoot is a Guile, Guile is a Scheme, Scheme is a Lisp, one with “proper tail calls”: function calls […]
Investigating SSMEC’s (State Micro) 486s with the UCA
Released in September 1989 by Intel, the legendary 486 CPU enjoyed widespread popularity in numerous PCs for many years before being gradually replaced by the Pentium and its successors. This era profoundly influenced the entire CPU industry for decades. Up until then, only Intel designed x86 microarchitectures, allowing third parties like AMD to produce Intel’s […]

Aeon: OpenSUSE for Lazy Developers
The openSUSE project recently announced the second release candidate (RC2) of its Aeon Desktop, formerly known as MicroOS Desktop GNOME. Aside from the new coat of naming paint, Aeon breaks ground in a few other ways by dabbling with technologies not found in other openSUSE releases. The goal for Aeon is to provide automated system […]
Hardware FPGA DPS-8M Mainframe and FNP Project
We’re excited to announce an ambitious long-term project, currently in the early stages, to implement as much of the DPS‑8/M mainframe architecture as possible using one (or more) FPGAs — with the ability to run the full Multics operating system — is now underway, led by Dean S. Anderson. In the early 1980s, Dean started […]

El Niño forecasts extended to 18 months with physics-based model
Interactions of El Niño with other climate patterns lead to enhanced El Niño predictability. Credit: Sen Zhao, UH SOEST. Across Asia, the Pacific Ocean, and the Americas, El Niño Southern Oscillation (ENSO) brings variations in winds, weather, and ocean temperature that can cause droughts, floods, crop failures, and food shortages. Recently, the world has experienced […]
Australia’s giant lizards help save sheep from being eaten alive
Jameson compared the scavenging activity of different animals by leaving dead rats at feeding stations, with camera traps, across the landscape. Credit: Tom Jameson Giant lizards called heath goannas could save Australian sheep farmers millions of dollars a year by keeping blowfly numbers down—and must be prioritized in conservation schemes to boost native wildlife, say […]
Surprising Phosphate Finding in NASA’s Osiris-Rex Asteroid Sample
Early analysis of the asteroid Bennu sample returned by NASA’s OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as we know it. Dominated by clay minerals, particularly serpentine, the sample mirrors the type of rock found at mid-ocean ridges on Earth. The magnesium-sodium […]
