Dual interfacial H-bonding-enhanced deep-blue hybrid copper–iodide LEDs

news.ycombinator.com Unknown 2025-07-17 05:27:58

Solution-processed light-emitting diodes (LEDs) are emerging as a promising technology for advanced solid-state lighting (SSL) and display industries, owing to their energy-efficient, low-cost, and straightforward manufacturing processes1-3. In this realm, lead-halide based perovskites4, organic semiconductors5, and colloidal core–shell quantum dots (QDs)6 have gained recognition as promising candidates. They have been utilized as emitting layers via solution processing and achieved impressive p

LLM architecture comparison

It has been seven years since the original GPT architecture was developed. At first glance, looking back at GPT-2 (2019) and forward to DeepSeek-V3 and Llama 4 (2024-2025), one might be surprised at how structurally similar these models still are. Sure, positional embeddings have evolved from absolute to rotational (RoPE), Multi-Head Attention has largely given way to Grouped-Query Attention, and the more efficient SwiGLU has replaced activation functions like GELU.

Trying Guix: A Nixer's impressions

Trying Guix: A Nixer's Impressions People occasionally ask me how I think Guix compares to Nix. Let me set the stage: I've been using Nix for many years, have large projects using Nix, used to be very active in the Nix community, and even wrote multiple Nix language interpreters, so I'd say that I'm at least fairly comfortable with Nix. I'm also one of those people who live in Emacs. I'm no stranger to Lisps (although my experience with Scheme is limited) and am very fond of them. It feels nat

Walt Disney Returns as a Surreal Animatronic for Disneyland’s 70th Anniversary

As of this week, Walt Disney returns to his original Magic Kingdom, with a little help from the magic-makers at Imagineering. Through the audio-animatronics technology Walt Disney introduced when he opened Disneyland 70 years ago, the evolution of the show robots has gone from static positioning with some movements, as first seen on the singing birds in the Enchanted Tiki Room, to a roaming animatronic of Uncle Walt.

Diffsitter – A Tree-sitter based AST difftool to get meaningful semantic diffs

diffsitter Disclaimer diffsitter is very much a work in progress and nowhere close to production ready (yet). Contributions are always welcome! Summary diffsitter creates semantically meaningful diffs that ignore formatting differences like spacing. It does so by computing a diff on the AST (abstract syntax tree) of a file rather than computing the diff on the text contents of the file. diffsitter uses the parsers from the tree-sitter project to parse source code.

5,000-Year-Old Rock Carving Is Among the Oldest Known Depictions of an Ancient Egyptian Ruler

An ancient rock engraving in the Lower Nile Valley may offer a rare glimpse into the origin of Egyptian kings. The art panel depicts an elite individual with features resembling those of early Egyptian rulers, from the very beginning of political unification across Egypt. Around 6,000 years ago, Egypt underwent a dramatic political transformation, ultimately leading to the formation of the Egyptian state under the first pharaoh, Narmer, around 3100 BCE.

When Figma starts designing us

I first encountered Figma in 2013, when Dylan Field demoed an early prototype to me at O’Reilly’s Foo Camp. I remember the pen tool feeling surprisingly elegant, but I missed the bigger picture: the radical implications of a design tool that ran in the browser. A decade later, Figma is a core part of our creative process, and without it, we wouldn't have been able to build a fully remote design practice.

Evidence of a 12,800-year-old shallow airburst depression in Louisiana

Introduction Cosmic airbursts and impacts produce a wide range of surface effects, with high-altitude airbursts, such as the 1908 Tunguska event, primarily generating blast damage without forming craters [1]. In contrast, low-altitude “touch-down” airbursts may induce surface melting, spherule formation, shocked quartz, and shallow cratering [2]. Due to preservation challenges, few airburst signatures are documented in the geologic record, limiting our understanding of these events. Here, we rep
