Give your coding agent a memory in one command — no signup, just a folder — LoreKit blog

Your agent re-solves yesterday's problem because nothing wrote it down. The fix isn't a platform you adopt — it's one command, a folder you own, and a loop that closes on your own disk. And when a team needs the same lore, it's a free account, one install with your key, and one command to bring everything you've already learned along.

Tell HN: Cloudflare silently injects its analytics when you switch nameservers 1

A few hours ago I switched my nameservers to Cloudflare in order to enable R2 bucket serving through my own subdomain, and I found out that it silently had injected a JS analytics snippet in my HTML-only JS-free site textlog.cc — I had to go to the Analytics dashboard, Add the site to the analytics and then disable the snippet. I find this approach entirely invasive, you should opt-in to features like that not have to opt-out. Just a warning out there to folks who might not be aware of this. [stagas]

Superconducting 2D cuprate with a single CuO2 plane | Nature

Atomically thin van der Waals crystals epitomize ideal material systems in the two-dimensional (2D) limit. This reduction in dimensionality often leads to important consequences, best exemplified by the emergence of new physics in graphene and other 2D materials that can be readily tuned by gating1,2. Vast opportunities arise in extending this top-down approach to other material systems. Recent experiments have demonstrated that the essential physics of high-temperature superconductivity in cuprates is contained within just two CuO2 planes3. Here we push dimensionality reduction to the extreme by examining a single layer of Bi2Sr2CuO6+δ (Bi-2201), which comprises only one CuO2 plane. In this ultimate 2D limit, we observe a robust dimensionality effect that manifests as an approximately 10% reduction in the optimal superconducting transition temperature. Moreover, this reduction in dimensionality offers unprecedented tunability—we successfully extended the phase diagram of Bi-2201 into uncharted territories via finely controlled oxygenation of single-monolayer specimens. Leveraging this tunability, we discovered that an anomalous metal state emerges between the insulating and superconducting states as the temperature approaches zero. Concurrently, we observe an anomalous scaling behaviour characterized by a divergent critical exponent. These findings illuminate the nature of the superconductor-to-insulator quantum phase transition in cuprates. A high-quality, pristine monolayer cuprate superconductor with a single CuO2 plane is fabricated and used to identify two quantum critical phenomena emerging between the Mott insulating phase and the superconducting phase.
