Antifragile, the opposite of fragile, is a term that describes systems or organisms that benefit from variability, volatility, and randomness. This concept, with a precise mathematical definition, extends beyond financial risk analysis to various fields. The Applied Antifragility Group proposes three Paths for designing antifragile systems: intrinsic, inherited, and induced antifragility. Intrinsic antifragility focuses on […]
This report discusses performance improvements in versions hrev57802 through hrev57900, focusing on eliminating bottlenecks in the system. True vectored I/O for non-cached disk reads/writes was implemented for faster data handling, uncovering and fixing bugs along the way. The CPU time profiler and kernel locking issues were addressed to enhance system stability. Additional improvements include support […]
Spice achieves efficient parallelism in Zig with sub-nanosecond overhead using heartbeat scheduling. Threads never compete, and adding more threads won’t slow down the program. Comparing to Rayon, Spice shows lower overhead, providing linear speed-up at first. Spice might scale slightly worse, but its low overhead ensures practical speed-up. The benchmark scenario highlights Spice’s ability to […]
The GhostWrite vulnerability impacts T-Head XuanTie C910 and C920 RISC-V CPUs, allowing unprivileged attackers to manipulate memory and peripheral devices. This critical hardware bug cannot be fixed without disabling significant CPU functionality. RISC-V, an open ISA, offers an alternative to expensive x86 and ARM licensing, leading to a diverse ecosystem. Despite the potential impact on […]
In just around 30 minutes, you can self-host the entire planet using the OSM project. With simple commands like mkdir and wget, you can set up a server and view the planet map in your browser. Requirements include podman or docker and 90 GB of storage. The unique aspect is the quick setup and the […]
A-Alpha Bio is a promising biotech startup founded by two graduate students with the aim to solve the data problem in protein-protein interactions. Their method, AlphaSeq, utilizes yeast cell mating to gather protein interaction data at scale, unique to any competitors. While there are some outstanding concerns about post-translational modifications and scalability, AlphaSeq has shown […]
Young adults are facing a higher risk of cancer than ever before, with increasing rates of diagnosis and mortality. Millennials and Generation X are at a higher risk of 17 types of cancer compared to older generations. Regular screenings are essential for early detection, saving lives through less intensive and expensive treatment. However, only 20% […]
The article recounts the tale of Stanford researchers who challenged the U.S. government’s monopoly on cryptography in the 1970s. Introducing revolutionary cryptographic principles, their work drew ire from the NSA, sparking a battle between privacy-conscious technologists and security-focused government officials. Facing legal threats for publishing their findings, the researchers prevailed, initiating the democratization of cryptographic […]
Blitz is a lightweight, modular, and extensible web renderer created for the “Dioxus Native” project. It utilizes a native Rust API instead of a JavaScript engine, allowing for direct interaction with Rust reactivity/state management libraries. The Blitz project includes two frontends: an HTML/markdown renderer and a Dioxus VirtualDom renderer. It builds upon various technologies including […]
