Summary: The authors of this study have successfully synthesized polycrystalline LK-99-like ceramic samples using a solid-state-sintering method. The samples were found to contain $mathrm{Pb_{10-x}Cu_x(PO_4)_6O}$ and $mathrm{Cu_2S}$, as confirmed by powder X-ray diffraction. Interestingly, the authors observed “half levitation” in some small flaky fragments when placed on a $mathrm{Nd_2Fe_{14}B}$ magnet. Magnetization measurements revealed the presence of […]

In this web content, the author discusses how they have implemented snappy user interfaces (UIs) in their web app using WebAssembly and Web Workers. They explain that WebAssembly allows developers to use low-level code in a binary format, resulting in faster execution than JavaScript alone. They specifically utilize AssemblyScript, which allows them to write high-level […]
devlooper is a program synthesis agent that autonomously fixes its output by running tests. It utilizes a sandbox to run tests and iterates until all tests pass, updating the code and fixing the environment as necessary. The project uses environment “templates” to define the setup and test harness for different languages/frameworks. A sandbox is used […]

TL;DR: WarpStream is a data streaming platform that is compatible with Kafka’s protocol. It runs on top of S3 and eliminates the need for local disks, brokers, and ZooKeeper. The platform is significantly cheaper than Kafka due to its direct streaming to and from S3, reducing infrastructure costs. However, Kafka’s replication strategy leads to high […]
Sandy Bridge, a microarchitecture developed by Intel, was a highly successful design in the early 2010s. It inherited features from prior Intel architectures but cannot be considered a member of any specific line. Sandy Bridge CPUs still deliver enough performance to remain usable across a range of everyday tasks. The microarchitecture has several unique features, […]
