Apple silicon chips have two types of CPU cores: E (Efficiency) cores that are energy efficient but slower, and P (Performance) cores that run most of the code in apps. The allocation of threads to different cores depends on the Quality of Service (QoS) assigned to each thread and clustering. VMs are allocated virtual CPU […]

Generative AI refers to a type of artificial intelligence that can generate new content without explicit programming. It uses machine learning algorithms to analyze datasets and create new content like images, music, text, and video. Generative AI has many uses, including content creation, data augmentation, simulation, personalization, and predictive analysis. Generative Adversarial Networks (GANs) and […]
Cascade is a RISC-V CPU fuzzer that focuses on generating valid, long, and complex programs to detect bugs. It has outperformed all existing fuzzers by discovering 37 new bugs in 5 RISC-V CPUs, resulting in 29 new CVEs. Existing fuzzers have limitations such as short programs, poor control flow management, and limited coverage of the […]

In Japan, the color green is often referred to as “ao,” which historically meant blue. This is because the Japanese language originally had only four basic color words: black, white, red, and blue. When the word “midori,” meaning green, entered the language, it was still considered a shade of blue. This linguistic challenge has had […]
In this web content, the author delves into the concept of Base64 encoding and its purpose. They emphasize the importance of understanding Base64 encoding beyond blindly copying and pasting code snippets. The author explains that Base64 encoding converts binary data into ASCII text using a specific set of characters, ensuring that the data is not […]
The author of this content is pondering the nature of operations work and how people thrive and grow in this role without being consumed by the systems they support. They observe that the skills that make someone effective in operations often come from experiences outside of technology, such as navigating unstable situations. These skills are […]
Hackweek 22 at SUSE allowed employees to work on personal projects, and the author chose to build a unikernel that runs WebAssembly. The application developer faces challenges when porting an application to a unikernel, as it requires support for the target unikernel and possible patching. On the other hand, targeting a WebAssembly platform provides clear […]
