Tim Cook will become Apple's executive chairman on September 1, 2026, while John Ternus will take over as CEO. Ternus has been with Apple for 25 years and has overseen many groundbreaking products.
The author of Zef, a dynamic language, implemented several optimizations to improve its performance, achieving a 16x speed-up and bringing it into the ballpark of QuickJS, CPython, and Lua. The optimizations included changes to the value representation, parser, hashtable usage, and object model, as well as the introduction of inline caches, watchpoints, and specialized AST nodes.
The author explains the megamerge workflow in Jujutsu, a powerful technique for working on multiple branches simultaneously, reducing merge conflicts and switching between tasks. The megamerge workflow involves creating an octopus merge commit as the parent of all working branches and using Jujutsu's absorb and squash commands to incorporate new changes.

We are open-sourcing the Kimi Vendor Verifier (KVV) project to ensure open-source models run correctly everywhere. KVV includes Pre-Verification, AIME2025, K2VV ToolCall, Upstream Fix, Pre-Release Validation, and Continuous Benchmarking to improve model accuracy and trust.
Ternary Bonsai is a new family of 1.58-bit language models that balance memory constraints with high accuracy. They achieve a 9x smaller memory footprint than standard 16-bit models while outperforming peers in their class.
a 2-layer transformer model is implemented on a commodore 64 using 6502/6510 assembly, with 25,000 int8 parameters and real-time processing. the model is trained with quantization-aware training and produces responses in several minutes.
ggsql is a new data visualization tool that uses SQL syntax to create rich, structured visualizations, making it easy for SQL users to create custom plots. The tool is designed to be powerful, ergonomic, and safe, with a focus on integrating with AI agents and code-based reporting tools, and is currently available in alpha release.
AES-128 is safe against quantum computers due to the difficulty of parallelizing Grover's algorithm, making it impractical to break with current technology. Experts, including NIST, agree that AES-128 remains secure for decades to come, and no key size changes are necessary as part of the post-quantum transition.
ADWEEK MiniMBA in Marketing helps leaders shape media strategy with confidence. StackAdapt is testing ads in ChatGPT with low CPMs and discounted fees for early access.

Culling is a crucial optimization technique in game development that reduces unnecessary work by skipping objects, triangles, or lights that are not visible to the player. Various culling techniques, including distance, frustum, occlusion, and meshlet culling, can be combined and layered to achieve the best results, with the goal of being conservative with correctness and aggressive with wasted work.
Government urges staff to switch from Silicon Valley to Visio platform. France and Germany disagree on detoxing from Big Tech, with France filing a complaint against Kick.
A climate scientist's 1200-year cherry blossom record is being passed on after his death, with a Tokyo-based environmental biophysicist taking over. The record is significant as cherry trees are sensitive to temperature changes, blooming earlier with global warming.
Kefir is an independent C17/C23 compiler developed by Jevgenij Protopopov, validated with 100 software projects and targeting x86_64 architecture.
Deezer reports a surge in AI-generated music uploads, with 60,000 tracks daily, but 85% are detected as fraudulent. The company will no longer store hi-res AI tracks and labels them for transparency.
To use the extension, install the native stub program on your computer and a browser extension. The native stub requires a specific operating system and kernel version.
The Earthquake Event Page application supports most recent browsers, view supported browsers. Or, try our Real-time Notifications, Feeds, and Web Services.
Zero-copy techniques are used in high-performance database engines to eliminate CPU copies between kernel and user space buffers, improving performance under high load. In Rust, this is achieved by using references and lifetimes to create borrowed views into existing bytes, rather than making owned copies, and structuring the API to reflect the underlying invariants.
The US has attempted to equip its entire tactical air fleet with the F-35, a masterpiece but expensive and limited platform, which may not be suitable for protracted wars. A balanced force with unmanned systems could hedge against the F-35's limitations and provide a more sustainable solution.
Someone wrote a unit test for @servo 10 years ago with a cookie expiry date of April 18, 2026, now the CI is broken. Maintainers suggest using system time or a library like TimeCop to make tests more robust.

Bloom is a platform that generates on-brand marketing assets in seconds, helping small businesses avoid template-like designs. It raised ~$1M from YC and notable investors, aiming to build a Brand OS system.
Nebula 1.10 adds IPv6 support, a new certificate format, and multiple IP addresses per host. This release enables future-proof networking with flexibility and security.
Researchers measured the "flinch" in pre-trained language models, a gap between the probability a word deserves and the probability the model assigns it. The flinch varies by lab and year, and abliteration, a popular post-training intervention, actually makes models more likely to deflect charged words.

Saunas have a therapeutic effect and promote cardiovascular health by stimulating the heart and increasing blood volume. Sauna use is linked to better same-day recovery, with lower nighttime heart rates and increased activity.
The C standard library's string.h functions, such as memcpy, are often implemented as built-in functions by the compiler due to their importance in program speed, and can be optimized using x86 assembly instructions like rep movsq and SIMD extensions. The glibc's implementation of these functions, such as memcpy and memset, uses indirect functions that can choose the most efficient ...
Kimi K2.6 is a state-of-the-art open-sourced model featuring long-horizon execution, agent swarm capabilities, and strong improvements in coding tasks. It demonstrates exceptional reliability, instruction following, and out-of-distribution generalization, setting a new bar for open-sourced models in agentic workflows.
I spent 3 years building Unity games by copying tutorials and stitching forum scripts together. Then an interviewer asked me what Queue<T> was. I could not answer.
