Gpumkat a shader debugger for metal which is designed to do what instruments can’t do

If you've ever worked with Metal and wished for a more in-depth way to analyze performance, debug shaders, and optimize your compute workloads, you might find gpumkat useful. It's a tool designed for macOS that gives detailed insights into GPU kernel execution—going beyond basic profiling to provide metrics like: ✅ Performance Analysis (execution time, memory usage, cache hit rates) ✅ Energy Consumption Tracking (power efficiency breakdowns) ✅ Shader Optimization Recommendations ✅ Thread Execution & Stack Traces ✅ Custom Debugging with Breakpoints & Step-by-Step Execution ✅ Recording Timelines & Async Debugging It also includes a low-end GPU simulation mode, which is

The first Nvidia RTX 5090 laptop benchmarks have emerged

Highly anticipated: Nvidia’s RTX 50 series laptops go on sale in a few days, and the first reviews of the company’s new flagship mobile GPU are now online. Although the laptop RTX 5090 closely resembles its predecessor in some tests, a more complete picture will likely emerge once a wider range of notebook models featuring the graphics card become available. Notebookcheck, ComputerBase, Hardwareluxx, PCMag, and other outlets recently received one of the first gaming laptops to feature Nvidia’s RTX 5090. Similar to results from the desktop sector, most early benchmarks demonstrate minor performance uplifts compared to the 4090. Each review

How Many Microplastics Are You Eating? 10 Foods With More Than You Think

Microplastics have been under the microscope lately, especially considering it’s estimated that people consume between 39,000 and 52,000 microplastic particles yearly. That number goes up to 74,000 to 121,000 particles when you include those we breathe in. Microplastics have become such a part of our lives that a new study found a plastic spoon’s worth of tiny plastic shards in human brain tissue. That sounds bad, but exactly how bad is it? To dig deeper, we spoke with a family physician about what counts as a “safe” level of microplastics, which foods have the most and things you can do to limit

The Morning After: Will the US imported car tariffs work?

The US will on top of any existing tariffs on all cars produced outside its borders. Additional fees will be imposed on imported components too like engines, transmissions, powertrains and electrical components. There’s a number of carve outs for US-based companies, as well as those sourcing gear from Mexico and Canada. But the move has been taken under the guise of “protecting” America’s car industry from imports. Of course, hefty tariffs are no guarantee consumers will flock to buy American if other brands are pricier. We’ve been here before: The ’70s oil shock meant bulky and inefficient American cars were

Reddit’s 50% Stock-Price Plunge Fails to Entice Buyers as Growth Slows

Though it’s stock price is still up 200% from its IPO in March of 2024 — last week Reddit’s stock had dropped nearly 50% since February 7th. And then this week, it dropped another 10%, reports Bloomberg, citing both the phenomenon of “volatile technology stocks under pressure” — but also specifically “the gloomy sentiment around Reddit…” The social media platform has struggled to recover since an earnings report in February showed that it is failing to keep up with larger digital advertising peers such as Meta Platforms Inc. and Alphabet Inc.’s Google, which have higher user figures. Reddit’s outlook seemed

rwindegger/msgpack23: A modern, header-only C++ library for MessagePack serialization and deserialization. msgpack.org[c++23]

A modern, header-only C++ library for MessagePack serialization and deserialization. msgpack23 is a lightweight library that provides a straightforward approach to serializing and deserializing C++ data structures into the MessagePack format. It is written in modern C++ (targeting C++20 and beyond) and leverages templates and type traits to provide a flexible, zero-dependency solution for packing and unpacking various data types. Header-only: Simply include the header and start using it—no additional build steps or dependencies. Modern C++: Uses C++ features like concepts to handle containers, maps, enums, time points, and user-defined types. Extensible: Allows you to define custom types by implementing
