Key idea: Posted: 2025-11-16A friend cleaned up and gave me a copy of a game I've not heard about before: Castrol Honda Superbike World Champions, a motorbike racing game for PC, released 1998 by Interactive Entertainment Ltd. and Midas Interactive Entertainment. Given the age of the game (and looking at the system requirements) it's clear that the game comes from the tricky era of early 3D-accelerated PC gaming. For context, my copy of the game helpfully asks to install DirectX 5.Before Windows was known for cramming AI and…

This phenomenon drives the shallow mixing that occurs in summer. As nights have warmed, however, this process has weakened, and mixing has slowed. Counterintuitively, as the layer of surface water has become warmer, it has also become thinner. βIn the summer, there is half as much warm water floating on the surface now, on average, than there was in 1971,β Girdner said.…

Those are valid options, but they come with complexity. You need to learn their APIs, manage their infrastructure, and deal with their quirks. Sometimes you just want something that: Works with your existing database Doesn't require external services Is easy to understand and debug Actually finds relevant results That's what I built. A search engine that uses your existing database, respects your current architecture, and gives you…

This is common in cases of public man-made death. During Mao Zedongβs disastrous Great Leap Forward, from 1958 to 1961, the Chinese government released no accurate mortality data. Observers abroad understood that a hunger crisis was under way when China began importing grain, but the scale of the catastrophe was not…

Participants were better able to remember prior images that they had rated highly on the three aspects of insight. This suggested that the insight-memory advantage was real, but the team wanted to see what was going on under the hood. Did brain activity during insight predict better memory five days later? The researchers found that the…

Key idea: Sunday 16 November 2025An overly aggressive mock can work fine, but then break much later. Why?In Why your mock doesnβt work I explained this rule of mocking:Mock where the object is used, not where itβs defined.That blog post explained why that rule was important: often a mock doesnβt work at all if you do it wrong. But in some cases, the mock will work even if you donβt follow this rule, and then it can break much later. Why?Letβs say you have code like this:#Β user.pydefΒ get_user_settings()Β ->Β str:Β Β Β Β withΒ open(Path("~/settings.json").expanduser())Β asΒ f:Β Β Β Β Β Β Β Β returnΒ json.load(f)defΒ add_two_settings()Β ->Β int:Β Β Β Β settingsΒ =Β get_user_settings()Β Β Β Β returnΒ settings["opt1"]Β +Β settings["opt2"]You write…

Key idea: The expiry of key patents for LFP battery chemistry in 2022 transformed the EV industry. With technology now freely accessible, global battery strategies are shifting as former IP barriers fall. An LFP battery is a type of lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the cathode material. LFPβs appeal in the EV sector is clear: lower cost compared to batteries based on nickel and cobalt chemistries, low toxicity and good safety due to their superior thermal stability. Teslaβs use of LFP in some of…

Main takeaway: Yuri Arcurs | Getty ImagesGoldman Sachs analysts attempted to address a touchy subject for biotech companies, especially those involved in the pioneering "gene therapy" treatment: cures could be bad for business in the long run. "Is curing patients a sustainable business model?" analysts ask in an April 10 report entitled "The Genome Revolution.""The potential to deliver 'one shot cures' is one of the most attractive aspects of gene therapy, genetically-engineered cell therapy and gene editing. However, such treatments offer a very different outlook with regard to…
