Mozilla's new strategic plan focuses on developing and supporting open source AI implementations, but its core audience is overwhelmingly negative about the direction, citing concerns about user experience and privacy. The plan's goals seem disconnected from reality, and Mozilla's pivot to AI is likely a bet on the longevity of the AI bubble and a desperate attempt to diversify revenue away ...
Researchers used focused ultrasound to stimulate the olfactory bulb in the brain, inducing sensations of smells. They found that different focal spots corresponded to different smells and were able to replicate this on two people with a makeshift headset.

To get audio working on Lenovo Legion Pro 7i Gen 10, follow steps to patch Linux kernel and install NVidia DKMS drivers. Run commands to reset and reload audio, then calibrate speakers for proper function.
Pointer Authentication Code, or PAC, is an anti-exploit/memory-corruption feature that signs pointers so their use (as code or data) can be validated at runtime. PAC is available on Armv8.3-A and Armv9.0-A (and later) ARM architectures and leverages virtual addressing in order to store a small cryptographic signature alongside the pointer value. On a typical 64-bit processor a pointer is ...
Chinese researchers at the Shanghai Institute of Applied Physics successfully converted thorium to uranium in a 2 megawatt reactor, paving the way for clean nuclear energy. This achievement marks a major leap forward in thorium-based molten salt reactor technology.
I'm unable to summarize the input as it appears to be a jumbled collection of characters and does not form a coherent text.
Being a pop star has its pros and cons, including fun experiences like attending parties and wearing luxurious clothes, but also drawbacks like feeling embarrassed and being scrutinized by the public. It also comes with a level of expectation to be truthful all the time, which can be challenging for artists who want to maintain a persona or fantasy.
The Apple Silicon boot process begins with an immutable Boot ROM that initializes the hardware and establishes a Chain of Trust, using a Group ID Key (GID Key) to decrypt the Low-Level Bootloader (LLB) and enforcing strict code signing to prevent malicious firmware execution. The Secure Enclave Processor (SEP) is a fully independent computer-on-a-chip that runs its own kernel, manages its own ...
Building agents is complex and messy, with SDK abstractions breaking down when used in real-world scenarios. The user shares their experience with building an agent using the Vercel AI SDK and Anthropic SDK, highlighting the importance of explicit cache management and reinforcement learning.
The article discusses the evolution of blogging, particularly niche blogging, and its potential revival. It argues that well-written, topic-focused resources are disappearing from the web, leaving behind misinformation and AI-generated content.
In part 1 of this series of posts, I mentioned that I was surprised to find that naively running my GPU code on the CPU was only 5x slower, when I thought it would be 100x slower. In this post I will explain how I ended up making the CPU implementation much faster than on the GPU. As mentioned in part 1, I got the original GPU code compiled for the CPU, and then wrote a simple driver to call ...
