Amazon and Walmart May Issue Their Own Company-Crypto

gizmodo.com Matt Novak 2026-03-18 08:45:49

Retailers like Amazon and Walmart pay fees to credit card companies every time a customer uses their Visa or Mastercard. And it’s no secret that retailers are not happy with that chunk of change that gets siphoned off. But thanks to the emergence of digital money, these retailers are reportedly itching to get away from the big banks. In fact, they may even issue their own stablecoins, according to a new report from the Wall Street Journal. Amazon’s efforts to develop a stablecoin are still in t

Anne Wojcicki has been declared the winner of a bankruptcy auction for 23andMe, the genetics testing start-up she founded, prevailing over a rival bid from Regeneron Pharmaceuticals. TTAM Research Institute, a non-profit public benefit company also founded by Wojcicki, won the auction with a $305 million bid for the 23andMe assets, which will not come with any company liabilities attached. 23andMe filed for bankruptcy in March after rejecting several go-private offers from Wojcicki in recent y

Simplest C++ Callback, from SumatraPDF

news.ycombinator.com Unknown 2026-03-18 13:26:38

SumatraPDF is a Windows GUI application for viewing PDF, ePub and comic books written in C++. A common need in GUI programs is a callback. E.g. when a button is clicked we need to call a function with some data identifying which button was clicked. Callback is therefore a combo of function and data and we need to call the function with data as an argument. In programming language lingo, code + data combo is called a closure. C++ has std::function<> and lambdas (i.e. closures). Lambdas convert

Cyborg Embryos Offer New Insights into Brain Growth

news.ycombinator.com Charles Q. Choi 2026-03-15 05:11:17

Scientists have created cyborg embryos by implanting electrode arrays into the developing brains of frogs, mice, and salamanders. Although the researchers reject implants in human embryos as unethical, they suggest their technology might one day help study and treat neurodevelopmental conditions in children. The stretchable technology at the core of the electrode arrays could record brain activity while remaining soft enough to accommodate the children’s growth. Recording the activity of neuron

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features

Seastar Seastar is a fast, extensible build system for C, C++, and maybe soon, Rust and Zig as well. I believe that it should be easy to make, prototype, and iterate upon designs. While C is still one of our most widely used languages, it makes it hard to create programs easily, especially for beginners. Instead, Seastar aims to be more like Rust's tooling with cargo , but supporting seamless compilation across more languages. Running Seastar is very simple to build and run. Assuming you have

How fast can the RPython GC allocate?

news.ycombinator.com Cf Bolz-Tereick 2026-03-18 14:55:09

While working on a paper about allocation profiling in VMProf I got curious about how quickly the RPython GC can allocate an object. I wrote a small RPython benchmark program to get an idea of the order of magnitude. The basic idea is to just allocate an instance in a tight loop: class A ( object ): pass def run ( loops ): # preliminary idea, see below for i in range ( loops ): a = A () a . i = i The RPython type inference will find out that instances of A have a single i field, which is an i

How to modify Starlink Mini to run without the built-in WiFi router

news.ycombinator.com About Oleg Kutkov 2026-03-18 13:40:07

The Starlink Mini terminal is designed as a compact, all-in-one solution with an integrated Wi-Fi router. While this design is ideal for typical consumer use, certain applications—such as custom networking setups, embedded installations, or power-constrained environments—may benefit from removing the internal router entirely. In this article, I’ll detail the process of physically removing the built-in Wi-Fi router board from the Starlink Mini, allowing the terminal to operate solely via Ethernet

This post assumes some familiarity with typed functional programming, Lisp, and formal logic. Today we will attempt to write a truth oracle in Lisp. By "truth oracle," I mean a program that can determine whether arbitrary mathematical statements are true or false. This might sound impossible, due to first-order logic being undecidable, but let's try anyway. Before that, though, we need to go over some required concepts.
