In their research, the team introduces Relational Keypoint Constraints (ReKep) as a visually-grounded representation for robotic manipulation tasks. This method allows for the optimization of robot actions in real-time without the need for task-specific training or environment models. By using large vision models and vision-language models, ReKep can be generated from free-form language instructions and […]

In the past few weeks, I worked on a Go website, learning new things. Go 1.22 has better routing capabilities, eliminating the need for external routing libraries like gorilla/mux. A potential issue is the built-in router’s redirect behavior with trailing slashes, easily resolved by using API endpoints without slashes. sqlc simplifies generating code for DB […]
Scientists have developed a groundbreaking flexible programmable chip, the Flex-RV, utilizing the non-silicon material IGZO with open-source RISC-V architecture. This chip can enable innovative applications such as a flexible ECG patch to detect arrhythmia conditions through machine learning. The Flex-RV is cost-effective, running at 60 kHz and consuming less than 6 milliwatts, suitable for sensors […]
The author delves into the mystery of IBM PC model numbers, revealing that information about the original PC is surprisingly scarce. IBM used a numbering scheme for peripherals and accessories, but official documentation prior to 1983 is non-existent. The oldest confirmed model numbers are from March 1983, establishing key PC models like 104, 114, 164, […]

The author discusses the disassembly and reverse-engineering of an attitude indicator for the F-4 fighter plane, a complex instrument used to show the aircraft’s orientation in three axes, including azimuth. The post explores the mechanical and electrical construction of the indicator, highlighting the rotating ball mechanism and the motors responsible for its movement, controlled by […]
Iceoryx2 v0.4.0 has been released, offering advanced features for fast inter-process communication without the need for a central daemon. It boasts unparalleled speed, up to 10 times faster than its predecessor, with dynamic memory pool configuration and advanced QoS settings. The API is highly modular and customizable, supporting C, C++, and upcoming language bindings. New […]
Author provides an in-depth overview of the cross-architecture portability problems, focusing on the issues caused by the use of a 32-bit time_t type. They highlight the impending 2038 disaster for Gentoo systems, where 32-bit applications will begin to fail due to this limitation. The post explores solutions such as transitioning to a 64-bit time_t type, […]
The author shares their experience with the Crystal programming language, describing it as a strongly-typed Ruby with lots of type inference. They note that the language is compiled to native executables through LLVM and is convenient to learn with due to its lack of a main() function. The tutorial features editable online code blocks for […]
