The result is a more feature rich, stable, and maintainable Ghostty on Linux and BSD.

news.ycombinator.com Mitendra Mahto 2025-11-17 08:05:24

This post is part of a series. Part 1 - A deep dive into connection management challenges. Part 2 - The nuances of HTTP parsing and why it’s harder than it looks. Part 3 - The intricacies of service discovery. Part 4 - Why Load Balancing at Scale is Hard. Load Balancing One of the most critical roles for a reverse proxy is load balancing requests across different upstream hosts. From a list of upstream servers, the proxy must decide where each incoming request should go. The primary goals

A large number of protocols on Ethereum and Solana blockchains have no revenue

news.ycombinator.com Omkar-Godbole 2025-11-30 23:20:53

Have you heard of disguised unemployment? It refers to a situation where a portion of the workforce appears to be employed, but isn't contributing to the economy's output. Consider the massive capital expenditure loss from ghost cities, which represent unoccupied infrastructure. Something similar can be said for the top smart contract blockchains, which hosts hundreds of decentralized protocols. Of these, only a minority are generating revenue, while the rest produce no yield, loosely represent

New adhesive surface modeled on a remora works underwater

arstechnica.com Unknown 2025-11-30 12:08:48

Most adhesives can’t stick to wet surfaces because water and other fluids disrupt the adhesive’s bonding mechanisms. This problem, though, has been beautifully solved by evolution in remora suckerfish, which use an adhesive disk on top of their heads to attach to animals like dolphins, sharks, and even manta rays. A team of MIT scientists has now taken a close look at these remora disks and reverse-engineered them. “Basically, we looked at nature for inspiration,” says Giovanni Traverso, a prof

Airbnb guest says host used AI-generated images in false $9,000 damages claim

techspot.com Rob Thubron 2025-12-14 18:15:00

WTF?! One of the many fears about AI use becoming widespread is that people can now alter images – sometimes convincingly – without any technical skills. An example of this surfaced recently when an Airbnb guest said a host manipulated photos in a false £12,000 ($9,041) damage claim. The incident took place earlier this year when a London-based woman booked a one-bedroom apartment in New York's Manhattan for two-and-a-half months while she was studying, reports The Guardian.

6 reasons why I prefer self hosted apps — and why you should too

Dhruv Bhutani / Android Authority Lately, there’s a lot of hype around self-hosting and running your own apps on a home lab or NAS. But you might be wondering what you stand to gain from it? After all, Google, Apple, and many others offer perfectly competent app suites. That’s what I thought too. But for the last few years, I’ve dived deep into the world of open source and self-hosting.

Ask HN: How will the OSA affect small Mastodon instances?

I am not currently a user of Mastodon, but I have some interest in the project. I was looking at some stuff that seemed to indicate to me that the OSA could make it difficult to self host Mastodon without providing age verification. I was then reading the provisions and realsised that it didn't really affect you unless you have at least 3 million monthly users, so in theory would not affect self hosters with only a few users.

Animated Cursors

Tattoy now supports animated cursors. It uses the same format as Ghostty, therefore rendering the cursor using custom shaders. Here are some popular Ghostty cursors, that you can use out-of-the-box with Tattoy. Even though Tattoy supports Ghostty cursors its rendering is quite different. Ghostty renders the cursor using actual pixels whereas Tattoy renders using UTF8 text-based "pixels", namely "▀" and "▄". This means that Tattoy cursors sometimes miss out on the subtleties of Ghostty cursors,
