Would you consider going a day without the internet? I did and I'll tell you why. Better yet, let me paint the picture for you. I stood on a ridge in the Sandia Mountains near Albuquerque, New Mexico, surrounded by pinyon trees and red-barked pines, listening to the trill of dark-eyed juncos jostling through the underbrush. Amid all this beauty, my phone chimed. And chimed again. And buzzed and beeped. A friend sent an Instagram link. Uber Eats offered a discount deal. Target had a coupon for

theverge.com Jess Weatherbed 2025-08-25 11:20:23

Eight new vulnerabilities, one of which cannot be fixed by patching the firmware, were discovered in 689 kinds of Brother home and enterprise printers by security company Rapid7. The flaws also impact 59 printer models from Fujifilm, Toshiba, Ricoh, and Konica Minolta, but not every vulnerability is found on every printer mode

IPv6 reaches majority use in 21 countries as Starlink and other providers modernize global connectivity

What just happened? The number of countries where more than half of internet connections use the IPv6 protocol has surged from 13 to 21 over the past year. This rapid progress, tracked by measurements from organizations such as Akamai, APNIC, Facebook, and Google, highlights both evolution and the growing influence of new connectivity providers, most notably Starlink. The most dramatic transformation has occurred in Tuvalu, a Pacific island nation with a population under 10,000. Until early 202

Why Go Rocks for Building a Lua Interpreter

news.ycombinator.com Roxy Light 2025-08-21 21:28:01

By Roxy Light I recently needed to build a custom Lua interpreter in Go. The exact reasons aren’t important for this blog post, but neither the reference implementation — which I will be referring to as “C Lua” throughout this article — nor the other open source Go Lua intepreters I could find were a good fit for my needs. Building a Lua interpreter ended up being a rather enjoyable months-long side quest. I’ve had a number of folks ask me to write about the experience since these sorts of proj

We need to talk about data integrity. Narrowly, the term refers to ensuring that data isn’t tampered with, either in transit or in storage. Manipulating account balances in bank databases, removing entries from criminal records, and murder by removing notations about allergies from medical records are all integrity attacks.

I can’t believe how far Switch emulation has come in the year since Nintendo killed it

Nick Fernandez / Android Authority It’s been a few weeks since the Nintendo Switch 2 hit shelves, but if we’re being perfectly honest, there’s not much reason to buy one yet. I’ve been revisiting my OG Switch to stave off the FOMO, but I was sad to learn that my left Joy-Con now drifts so badly that Link runs in circles like he’s drunk in Breath of the Wild.

The Best Printers for Home and Office: Brother, HP, and More

wired.com Brad Bourque 2025-08-25 07:33:00

Before anything else, you'll have to decide between ink and laser. I'll get into the details when it comes to each model, but the most important consideration is paper type, because it’s a limitation rather than a benefit. Laser printers use heat in the bonding process, which means if you regularly print on windowed envelopes or photo paper, you'll need to either use an ink printer or change to a thermally-safe alternative, which can be cost prohibitive if you print a lot. Inkjets are the most

This 3D printer is excellent, with fast, quality printing at a great price. Adding the AMS Lite elevates it to the best printer you can buy right now. Plus, its four-color printing capability for less than $700 is such a good deal; I'm still baffled by how the company pulls off that pricing.
