This self-hosted travel app has completely changed how I travel

Dhruv Bhutani / Android Authority Travel has always been a huge part of my life. Whether I’m planning a weekend getaway for a hike or a longer multi-country backpacking trip, I’ve relied on travel apps to help keep things organized. But after years of using some of the best travel apps like Wanderlog, TripIt, making notes in Google Keep or Notion, or even maintaining a pen and paper journal, I realized they all came with frustrating trade-offs. Too many ads, pushy upgrade prompts, opaque subscr

Will the Fear of Being Confused for AI Mean That We Will Now Write Differently?

news.ycombinator.com Unknown 2025-07-20 06:03:33

by David Beer Could there be anything more insulting for a writer than someone assuming that their writing is an output of generative artificial intelligence? The mere possibility of being confused for a neural network is enough to make any creative shudder. When it happens, and it will happen, it will inevitably sting. By implication, being mistaken for AI is to be told that your writing is so basic, so predictable, so formulaic, so replicable, so obvious, so neat, so staid, so emotionless, s

The Big LLM Architecture Comparison

news.ycombinator.com Sebastian Raschka 2025-07-20 06:56:01

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.

Renewed iPad Pros pair nicely with iPadOS 26, and they’re quite affordable right now

9to5mac.com Michael Burkhardt 2025-07-20 04:01:30

A short while ago, I was browsing Apple deals on Amazon (as one does) – and something stuck out to me. High-end iPad Pros, particularly 12.9-inch models, are surprisingly cheap. I saw M1 models with 1TB and cellular for nearly $600. Given the recent iPadOS 26 overhaul that makes the iPad much more Mac-like, I figured these deals would be worth a share. While renewed iPad deals are the focus here because of their affordability, new iPad deals are also mentioned at the end. Renewed M1 iPad Pro d

Intel to boost gross margins – new products must deliver 50% gross profit

From low-carb ice cream to keto protein bars to "sugar-free" soda, the decades-old sweetener erythritol is everywhere.

Trigon: Exploiting coprocessors for fun and for profit (part 2)

A few months ago, I released a kernel exploit called Trigon. It was significant in that it was deterministic - that is, it cannot fail.
