A comprehensive study of high-temperature superconducting magnets built by MIT and Commonwealth Fusion Systems confirms they meet requirements for an economic, compact fusion power plant.
C2y makes memcpy(NULL, NULL, 0) and other zero-length operations on null pointers well defined. This removes a source of bugs that may result in security issues.

Servers in the Oxide Rack will form the backbone of both the compute and storage services available to customers. The rack will be composed of a variety of hardware and software components, some of which represent resource-constrained or inflexible environments; e.g., the Service Processor (SP) or Hardware Root Of…
Learn how we enhanced TCP performance in Coder to achieve 5X faster throughput by optimizing buffer sizes, implementing the HyStart algorithm, and minimizing packet loss, significantly improving remote development experiences.
Media over QUIC: Rethink your approach. *Unless you're doing something dope.
2024-11-13 : An earlier version of this report asserted that consumers with auto-commit enabled could lose data by automatically committing offsets returned by the most recent poll. This claim was based in part on Confluent’s documentation , which states:

While deploying Precision Time Protocol (PTP) at Meta, we’ve developed a simplified version of the protocol (Simple Precision Time Protocol – SPTP), that can offer the same level of clock syn…
The demo shows that even though the behavior appears similar, TCP connections leak when using the io_uring driver but not with the epoll driver. I've also tested this across various io_uring runtimes, and it turns out to be a common issue across all of them.

With the recent release of Ubuntu 24.04, we at Snyk Security Labs thought it would be interesting to examine the latest version of this Linux distribution to see if we could find any interesting privilege escalation vulnerabilities.
A summary of a Codethink sponsored project which implements a cryptographically secure bootloader, written in Rust, for RISC-V.
SIMD in game development Often in game development we talk about SIMD. It is the holy grail of CPU performance, often out of reach. The conventional wisdom is that it is difficult to achieve real gains from SIMD. It is tempting to build a math library around SIMD hoping to get some performance gains. However, it often…
Project overview QEMU is a virtual machine which allows running an operating system inside of another. While there already is a Haiku port, it currently does not support any acceleration system through native virtualization (through Intel VT-x and …
