Learning Lens Blur Fields

news.ycombinator.com Unknown 2025-09-21 22:21:27

Lens blur field shown in step 2 is from the dual pixels of a Pixel 4a. Abstract Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements. To tackle this challenge, we introduce a high‑dimensional neural representation of blur—the lens blur field—and a practical method for acquisition. The lens blur field is a multilayer perceptron (MLP) designed to (1) accurately capture variations of the lens 2‑D point sprea

Pixel phones could soon let you set up unique vibrations for each contact (APK teardown)

androidauthority.com Unknown 2025-10-10 15:53:10

Adamya Sharma / Android Authority TL;DR We spotted Google Contacts code that hints at contact-specific vibration patterns for Pixel phones. Apple and Samsung already allow you to assign specific haptics to your contacts. If it rolls out, the feature would tell you who’s calling even when your Pixel is in silent mode. Pixel phones already let you set custom ringtones for individual contacts, but Google could be preparing to take things further. Code hidden in the latest version of the Google

WhatsApp Just Patched a ‘Zero Click’ Bug Being Used to Hack Apple Users

gizmodo.com Lucas Ropek 2025-10-17 23:50:34

On Friday, WhatsApp announced that it had patched a software vulnerability that was being used by unknown hackers to target specific users of Apple products and hack them with spyware. WhatsApp, which is owned by Meta, said in an advisory that the previously unknown bug “may have been exploited in a sophisticated attack against specific targeted users.” The vulnerability is officially dubbed CVE-2025-55177. TechCrunch notes that this week, WhatsApp fixed the bug while last week, Apple fixed an

Formal specs as sets of behaviors

news.ycombinator.com Lorin Hochstein 2025-12-21 15:13:55

Amazon’s recent announcement of their spec-driven AI tool, Kiro, inspired me to write a blog post on a completely unrelated topic: formal specifications. In particular, I wanted to write about how a formal specification is different from a traditional program. It took a while for this idea to really click in my own head, and I wanted to motivate some intuition here. In particular, there have been a number of formal specification tools that have been developed in recent years which use programmi

Working on a Programming Language in the Age of LLMs

news.ycombinator.com Unknown 2025-12-21 11:12:30

I’ve been working on Rye since 2018. It’s a project of joy — but also because I believe there is a potential to create something of value to others, eventually. Even people living under a rock know we’ve entered the age of LLMs. I don’t jump to ships too soon, but eventually, even I had to admit: code can get generated from prompts. And in many situations — with a smart prompter — the results are quite OK. Even if you disagree, genie can’t be put back in the bottle. Technical progress generall

Hill Space: Neural nets that do perfect arithmetic (to 10⁻¹⁶ precision)

news.ycombinator.com Justin Dujardin 2026-01-17 15:37:48

When understood and used properly, the constraint W = tanh(Ŵ) ⊙ σ(M̂) (introduced in NALU by Trask et al. 2018 ) creates a unique parameter topology where optimal weights for discrete operations can be calculated rather than learned . During training, they're able to converge with extreme speed and reliability towards the optimal solution. Most neural networks struggle with basic arithmetic. They approximate, they fail on extrapolation, and they're inconsistent. But what if there was a way to m

Prompting LLMs is not engineering

news.ycombinator.com Unknown 2026-01-31 20:38:04

Prompting LLMs is not engineering published in: With the proliferation of AI models and tools, there's a new industry-wide fascination with snake oil remedies called "prompt engineering". As of July 2025 the term is now "context engineering" or "context prompting" or "context manipulation". To put it succinctly, prompt engineering is nothing but an attempt to reverse-engineer a non-deterministic black box for which any of the parameters below are unknown: training set weights constraints o

The Best Meat Subscription Boxes, Tested and Reviewed (2025)

wired.com Scott Gilbertson 2025-11-10 00:33:00

The first reason ButcherBox earned our top spot is the packaging, which was much sturdier than several other boxes we tried. The last thing anyone wants is to come home to a box of spoiled meat. The second is sourcing transparency. While humane-washing is a real thing and ButcherBox does not disclose the names of specific farms it works with, it offers third-party oversight, like Certified Humane and USDA Organic certification. It’s not perfect, but it’s something. You can select from two subsc
