My First Look at T-Mobile's Unique Starlink T-Satellite Service Made Me Head Far From Home

cnet.com See Full Bio 2025-12-21 12:18:00

Is T-Mobile's new T-Satellite service worth $10 a month to be able to text from almost anywhere outside cellular coverage areas? The Starlink-based satellite service can be a convenience if you're camping or hiking remote areas, but also a communications lifeline for people who don't have regular cellular access or need emergency aid. To test it out, though, I had to find a cellular dead zone. T-Mobile estimates there are 500,000 square miles in the US with no cell coverage, so I left my home i

Principles for production AI agents

SIMD within a register: How I doubled hash table lookup performance

news.ycombinator.com Aleksey Maltsev 2025-12-23 08:41:34

While working on a Cuckoo Filter implementation in C#, I created an array-like structure for the underlying hash table. I chose an 8-bit fingerprint: it aligns nicely on a byte boundary and still keeps the false-positive rate around 3 %. The layout looked straightforward—just a byte array where the start of each bucket is calculated as bucketIdx * bucketSize . The size of each bucket is 4 slots, which is a solid choice for Cuckoo Filter. Bucket 0 3A 00 B7 F2 Bucket 1 4C 91 00 DE Bucket n AA 00

Google DeepMind's Aeneas model can restore fragmented Latin text

At its best, AI is a tool, not an end result. It allows people to do their jobs better, rather than sending them or their colleagues to the breadline. In an example of "the good kind," Google DeepMind has created an AI model that restores and contextualizes ancient inscriptions. Aeneas (no, it's not pronounced like that) is named after the hero in Roman mythology. Best of all, the tool is open-source and free to use. Ancient Romans left behind a plethora of inscriptions.

Driving the wooded highways of the North Cascades in Washington state, I deliberately pointed my car toward nothing. Specifically, I needed to get out of Seattle to find an area with no cellular coverage so I could try out T-Mobile's new Starlink-based satellite texting service, T-Satellite, with my phone.

A circle and a hyperbola living in one plot

We will see that the 3D plot of $x^2 + (y + zi)^2 = 1$, where $x$, $y$, $z$ are real and $i$ is the imaginary unit, contains both a circle and a hyperbola. This visualization sheds light on the complex eigenvalues of real matrices. Let’s start by expanding the equation $x^2+(y+zi)^2 = 1$ and separating it into real and imaginary parts. We get: \[\begin{align*} &\text{Real Part:} &x^2 + y^2 - z^2 &= 1, \\ &\text{Imaginary Part:} &yz &= 0. \end{align*}\] The condition $yz=0$ split
