Having fast, reliable home internet is essential these days for work, school, streaming and browsing. But understanding how much speed you need, or even what "internet speed" even means, can be a daunting task. Bandwidth and latency are two key factors that affect how we perceive the speed of our internet connection. But while you may hear them used together quite often, these two terms have distinct meanings. Understanding what they are and the difference between them can help you troubleshoot
Experimental archaeologist Greer Jarrett of Lund University in Sweden has been sailing in the footsteps of Vikings for the last three years. If you want to learn more about how and where the Vikings sailed, making the journey through the fjords yourself in replica boats is a practical, hands-on approach to achieving that end. Greer Jarrett, an archaeologist at Lund University in Sweden, has spent the last three years doing just that, sailing more than 5,000 kilometers along known Viking trade r
Verizon TL;DR A new leak has revealed details about Verizon’s new Project 624, which it first teased in April this year. Instead of offering something new, an internal document states that Project 624 aims to promote existing perks and double down on available rewards. Verizon also appears to be stocking new swag and goodies in its retail stores, with giveaways expected to begin on June 24. Verizon plans to introduce new perks and benefits for its customers in an effort to reverse its recent

Perched atop the Cerro Pachón mountain in Chile, 8,684 feet high in the Atacama Desert, where the dry air creates some of the best conditions in the world to view the night sky, a new telescope unlike anything built before has begun its survey of the cosmos. The Vera C. Rubin Observatory, named for the astronomer who discovered evidence of dark matter in 1978, is expected to reveal some 20 billion galaxies, 17 billion stars in the Milky Way, 10 million supernovas, and millions of smaller objects

OpenAI TL;DR A blog post announcing OpenAI’s $6.5B acquisition of Jony Ive’s hardware startup “io” has been taken down due to a court order stemming from a trademark complaint by a company called iyO. OpenAI clarified that despite speculation, the partnership with Ive is still ongoing, and it’s exploring options regarding the name dispute. iyO, which already sells an AI-powered “audio computer,” claims the “io” name infringes on their trademark. All traces of OpenAI’s much-hyped hardware ven
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;
For a while, X terminals were a reasonably popular way to give people comparatively inexpensive X desktops. These X terminals relied on X's network transparency so that only the X server had to run on the X terminal itself, with all of your terminal windows and other programs running on a server somewhere and just displaying on the X terminal. For a long time, using a big server and a lab full of X terminals was significantly cheaper than setting up a lab full of actual workstations (until inexp
What is the best internet provider in Anaheim? AT&T Fiber is CNET's top pick for the best internet service provider in Anaheim. The internet service provider is the best option for most households in the city because of its fast, symmetrical speeds that come with straightforward plan terms and reasonable pricing. Not every address in Anaheim is served by AT&T Fiber. For those outside the coverage area, options like Spectrum or T-Mobile Home Internet are also solid picks, depending on what’s ava

If you recently looked up but couldn’t find OpenAI’s announcement video about its flashy partnership with Jony Ive, you are not alone. OpenAI has quietly pulled down the original blog post and the accompanying nine-minute video, just weeks after touting the $6.5 billionsc deal as a landmark step toward building new AI hardware. Here’s what happened. The deal is still happening, just with a bit less branding According to a statement given to The Verge, OpenAI says the content was taken offline
Perplexity is planning to open up its Comet browser that's powered by "agentic search" to Windows users, according to the company's CEO. Aravind Srinivas posted on X that the Windows build of Comet is ready and has sent out invites to early testers already. Perplexity's CEO also hinted at a potential release for Android devices, adding that it was "moving at a crazy pace and moving ahead of schedule." In May, Perplexity launched a beta version of its AI-powered Comet browser, only available to
The complete guide to salary negotiation for engineers and other professionals who think negotiating is morally questionable. Until I ran VaccinateCA my single most important career contribution might have been writing about salary negotiation. That essay has been read by millions of people.

Recently, there has been a lot of talk about the “decline of the literary (straight) (white) male.” The marginal benefit provided by an additional take on this topic, some clever new angle walking the tightrope between edgy and politically correct, is rapidly approaching zero. The problem with these articles—and the discourse as a whole—is that none of them go far enough. There is an impassable chasm between the stardom of Mailer, Updike, McCarthy, DFW, Franzen, etc and whoever is getting fello

OpenAI has pulled a much-discussed video promoting the friendship between CEO Sam Altman and legendary Apple designer Jony Ive (plus, incidentally, OpenAI’s $6.5 billion deal to acquire Ive and Altman’s device startup io) from its website and YouTube page. Does that suggest something is amiss with the acquisition, or with plans for Ive to lead design work at OpenAI? Not exactly, according to Bloomberg’s Mark Gurman, who reports that the “deal is on track and has NOT dissolved or anything of the
What just happened? Intel is preparing for a major transformation of its marketing operations, marking a significant shift in how the company approaches customer engagement and internal organization. Under the direction of newly appointed CEO Lip-Bu Tan, the technology giant will outsource a substantial portion of its marketing work to Accenture, a global consulting firm, with artificial intelligence playing a central role in the transition. This move is expected to result in significant layoff
2022-06-01 How fast are Linux pipes anyway? The challenge, and a slow first version # First of all, let’s start with measuring the performance of the fabled FizzBuzz program, following the rules laid down by the StackOverflow post: % ./fizzbuzz | pv >/dev/null 422GiB 0:00:16 [36.2GiB/s] pv is “pipe viewer”, a handy utility to measure the throughput of data flowing through a pipe. So fizzbuzz is producing output at a rate of 36GiB/s. fizzbuzz writes the output in blocks as big as the L2 cache,
Researchers used the low-temperature additive manufacturing process to build the glass cups above. The optical behavior of the printed cups can be tailored by altering the chemical components of the inks. Additive manufacturing (3D printing) holds promise for fabricating complex glass structures that would be unattainable with traditional glass manufacturing techniques. Lincoln Laboratory’s innovative approach allows additive manufacturing of multimaterial glass items without the need for costl

A new AI darling is making waves in Silicon Valley. It’s called Perplexity, and according to reports, both Meta and Apple have quietly explored acquiring it. 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. But here’s the thing: it mostly just summarizes web results and sends you links. So why the frenzy? Perplexity billed itself an “answer engine.” You ask a question, and it uses large

AT&T offers a range of internet plans with speeds ranging from 300Mbps to 5,000 megabits per second (5 gigabits per second). This makes it one of the top providers, ideal for busy households and businesses that need fast and reliable internet. But with speeds that high, you'll need to prepare to spend more than usual.

Monotype is keen for you to know what AI might do in typography. As one of the largest type design companies in the world, Monotype owns Helvetica, Futura, and Gill Sans — among 250,000 other fonts. In the typography giant’s 2025 Re:Vision trends report, published in February, Monotype devotes an entire chapter to how AI will result in a reactive typography that will “leverage emotional and psychological data” to tailor itself to the reader. It might bring text into focus when you look at it and

CNET's key takeaways The ErgoAlign Mattress Topper from Helix normally costs $499 but it's on sale right now for $374 for the queen and $328 for the full size. It's a comfortable, band-aid solution until my next big mattress purchase. But it's pricier than other mattress toppers. The Nest Bedding Cooling Topper is $100 less, for example. I'm reaching the eight-year mark with my current mattress -- it's time to shop for a new one. But when I look around at the available mattress options, I ge
