Nvidia has announced details about its new silicon architecture, the first data center GPU built using that architecture, and plans to build the world's fastest AI supercomputer. The new Hopper architecture is designed to accelerate the training of Transformer models on Nvidia's new H100 GPUs by six times compared to previous-generation chips. The H100 GPU contains 80 billion transistors and has a memory bandwidth of 3TB/s. It will allow models to be trained in days rather than weeks. Eos will be a supercomputer built using the Hopper architecture and offer 18.4 exaflops of AI performance.

The Lapsus$ group claims that it stole data from Microsoft and Okta, a Single-Sign-On provider. It posted images showing proprietary data on its Telegram channel to prove that it gained privileged access to both companies' systems. The group released a 37GB file archive containing source code for Bing, Bing Maps, and Cortana. Okta says that the impact of its data breach is limited, but Lapsus$ claims that it can reset passwords and multifactor authentication for most of Okta's clients.

Elon Musk announced during a speech to Tesla Gigafactory Berlin employees that the company is working on creating a manganese battery cell. Manganese will allow Tesla to create batteries with 50% more cell volume with the same amount of nickel. Tesla estimates that 300 terawatt-hours of battery cell production will be needed for the planet to fully transition into a sustainable world, so the batteries will need to be created out of common materials. A video of Musk's speech at Gigafactory Berlin is available in the article.

A Californian company claims that it can decode almost all of the DNA in days-old embryos created using in vitro fertilization. The technique requires fully sequencing both parents' DNA and reconstructing the embryo's genome with the help of the data. While the technique could be used to screen for genetic diseases, the science of screening embryos for genetic diseases is still new and primarily used only in research. There are still many limitations to the technology and scientists are still learning about what works.

Cirrus is an SCSS framework for the modern web. It doesn't require JavaScript for interaction or functionality and all components are configurable. Cirrus' design system uses utility functions, which allows developers to create consistent user interfaces. Examples are available.

This page contains a code review pyramid focuses on the sections that matter the most during a code review. It also shows parts that could and should be automated. The most important sections are API and implementation semantics, followed by documentation, tests, and code style, in order. The image provides questions to ask for every section.

Unity has released a tech demo that demonstrates what its game engine is capable of. 'Enemies' is a 2-minute long video that shows a detailed room and an almost realistic human being, all rendered by the popular game development engine. It shows how Unity can compete with Epic Games' Unreal Engine. The video is available in the article.

Invisibility Shield Co, a British startup, claims to have created an invisibility shield that doesn't require power to operate. It is financing its invention through Kickstarter. A full-sized invisibility shield measures three by two feet and costs around $400. The technology works by reflecting light in a horizontal direction so that the subject behind the shield is almost completely obscured. A video from the startup showing the shield working in several environments is available.
