Exploring Coroutines in PHP

news.ycombinator.com Doeke Norg 2026-02-03 04:34:13

The term "coroutine" often comes up when talking about asynchronous or non-blocking code, but what does it actually mean? In this post, we will explore coroutines as a concept and see how PHP supports them through Generators and Fibers. Whether you're building pipelines, CLI tools, or preparing to dive into concurrency, understanding coroutines is an essential first step. What are Coroutines? A coroutine is a function. However, where a regular function continuously runs from top to bottom unti

Drive Capital’s second act — how the Columbus venture firm found success after a split

techcrunch.com Connie Loizos 2026-02-05 05:25:59

The venture capital world has always had a hot-and-cold relationship with the Midwest. Investors rush in during boom times, then retreat to the coasts when markets turn sour. For Columbus, Ohio-based Drive Capital, this cycle of attention and disinterest played out against the backdrop of its own internal upheaval several years ago — a co-founder split that could have ended the firm but may have ultimately strengthened it.

Summary: Individuals emphasizing freedom and hobbies experienced a boost in well-being, whereas those prioritizing achievement felt less happy. The research showed that valuing ‘hedonism’ and ‘self-direction’ led to increased happiness across India, Turkey, and the UK. In contrast, ‘achievement’ and ‘conformity’ values showed no direct happiness benefits. The findings spotlight the importance of balancing life pursuits for mental health.

Bcachefs may be headed out of the kernel

news.ycombinator.com Posted June 2026-02-10 16:32:10

Bcachefs may be headed out of the kernel The history of the bcachefs filesystem in the kernel has been turbulent, most recently with Linus Torvalds refusing a pull request for the 6.16-rc3 release. Torvalds has now pulled the code in question, but also said: I think we'll be parting ways in the 6.17 merge window. You made it very clear that I can't even question any bug-fixes and I should just pull anything and everything. Honestly, at that point, I don't really feel comfortable being involved

C. Scott Brown / Android Authority After spending a few years setting itself up, Nothing boldly launched the Nothing Phone 3 as its top-tier flagship this week. Coming in at $799, it takes on the proper flagships from Samsung, Google, Apple, and others. While one can argue that it comes out on top against these three, Chinese competitors like OnePlus can give it a run for its money with the OnePlus 13.

That XOR Trick (2020)

There are a whole bunch of popular interview questions that can be solved in one of two ways: Either using common data structures and algorithms in a sensible manner, or by using some properties of XOR in a seemingly hard to understand way. While it seems unreasonable to expect the XOR solutions in interviews, it is quite fun to figure out how they work. As it turns out, they are all based on the same fundamental trick, which we will derive in a bottom-up way in this post. Afterwards we will lo

Neural embedding models have become a cornerstone of modern information retrieval (IR). Given a query from a user (e.g., “How tall is Mt Everest?”), the goal of IR is to find information relevant to the query from a very large collection of data (e.g., the billions of documents, images, or videos on the Web). Embedding models transform each datapoint into a single-vector “embedding”, such that semantically similar datapoints are transformed into mathematically similar vectors. The embeddings are
