ExpressVPN vs. Surfshark: Two of CNET’s Favorite VPNs Compared

ExpressVPN and Surfshark are two heavyweights and sit comfortably among CNET’s top VPN picks thanks to their exceptional all-around performance and privacy protections. I use both ExpressVPN and Surfshark regularly and can tell you that each is excellent at what it does -- but also that each one does things very differently. That’s good, because there are distinctions between ExpressVPN and Surfshark that can make it easier to decide between the two based on your specific needs. In a perfect wor

Don't plug these 7 appliances (including AC units) into extension cords - according to professionals

Encounters with Reality on Christine Rosen's the Extinction of Experience

When I was fourteen, my family went on a Caribbean cruise. I have always been allergic to the idea of going somewhere for the explicit purpose of “having a good time.” But that’s exactly what a cruise—at least this particular kind of cruise—is: a never-ending parade of convenient entertainment and diversion. Gorge yourself at breakfast; use the coupon in your welcome bag for a mid-morning massage; have lunch brought to your table at the pool; shop luxury brands on the promenade in the afternoon;

I wrote my PhD Thesis in Typst

I wrote my PhD Thesis in Typst I recently submitted my PhD thesis, and while waiting for the physical copies to get printed I thought I'd write about something you (hopefully) wouldn't notice when reading it. I wrote it in Typst, not LaTeX. In this post I will talk a bit about what went well and what didn't. Typst (https://typst.app/) is a modern take on a typesetting language that I think has a real shot at dethroning LaTeX. I would describe the language as a mix of markdown and dynamically t

Valued at a staggering $14 billion following a May funding round, the startup is being hailed as a revolutionary threat to Google Search’s search dominance.

Requiem for a Solar Plant

Requiem for a Solar Plant The email landed like a brick through a plate glass window. "...requiring reconductoring of 1.71 miles at a cost of $795,150...limiting output to 3MW..." I stared at my laptop screen, the blue light illuminating the shadows under my eyes in my darkened California living room. Outside, endless February rain tapped against the windows like impatient fingers. My gut churned, a familiar discomfort that had become my constant companion over the past year. This wasn't just

Augmented Vertex Block Descent (AVBD)

Augmented Vertex Block Descent (AVBD) Vertex Block Descent is a fast physics-based simulation method that is unconditionally stable, highly parallelizable, and capable of converging to the implicit Euler solution. We extend it using an augmented Lagrangian formulation to address some of its fundamental limitations. First, we introduce a mechanism to handle hard constraints with infinite stiffness without introducing numerical instabilities. Second, we substantially improve the convergence in th

Having trouble opening Chrome? It may be Microsoft’s fault

Rita El Khoury / Android Authority TL;DR A bug is preventing Windows users from opening Google’s Chrome browser. The bug is connected to Microsoft’s Family Safety feature. There are a few workarounds, like renaming Chrome.exe to Chrome1.exe. Microsoft isn’t afraid to deploy tactics to nudge you away from Chrome.

Latest Starship Explosion Drastically Decreases SpaceX's Chances of Reaching Mars Without Having to Wait Years

"One of the toughest problems to solve." With tech billionaire Elon Musk out of the White House after his disastrous turn as a bureaucrat, he can now focus on more pressing subjects — such as his SpaceX Starship rockets that keep on exploding into fiery columns of fire, with the latest dramatic failure this past Wednesday in Texas, when the massive spacecraft hadn't even left the ground yet. This recent setback ratchets up the pressure on Musk even further, who faces a hard deadline and steep

BBC Threatens to Sue Perplexity, Alleging 'Verbatim' Reproduction of Its Content
