Why Ruby on Rails still matters

I found vinyl records from my late grandfather recently. It struck me how this media from the previous millennium played without issues. Vinyl represented a key shift in music distribution - it made printing and sharing sounds accessible, establishing a standard that persists. While audio sharing methods evolved, the original approaches remain functional. In our increasingly complex world, many people return to vinyl because it offers simplicity, stability, and longevity . Amidst the constant c

Sparse Voxels Rasterization: Real-Time High-Fidelity Radiance Field Rendering

Our scene representation is a hybrid of primitive and volumetric model. (a) Primitive component. We explicitly allocate voxels primitives to cover different scene level-of-details under an Octree layout. Note that we do not replicate a traditional Octree data structure with parent-child pointers or linear Octree. We only keep voxels at the Octree leaf nodes without any ancestor nodes. (b) Volumetric component. Inside a voxel is a volumetric (trilinear) density field and a (constant) spherical ha

Wheel of Time Season 3 Arrives Soon—Here’s What to Remember From Season 2

The Wheel of Time is preparing to crank back up again, with the first three episodes arriving March 13 on Prime Video; like seasons one and two, it’ll run eight episodes, with a weekly drop after the premiere through April 17. That mini-binge may be enough to plunge you back into Robert Jordan’s world (after yesterday’s amuse-bouche: the limited-time early release of the season’s fiery first 11 minutes), but if you need a reminder of where season two left off, io9’s got you covered. First, thou

Best Places to Buy Replacement Prescription Lenses Online in 2025

Some companies may expedite your order more quickly if you send them detailed info about your frames. It's important to know exactly what your prescription is (ideally a current one), although some companies can pull it from your old lenses if necessary. Check the site for discount codes or first-time buyer discounts (you usually have to provide your email address). The prescription for your glasses is typically only valid for a year or two. If it’s time to replace your current lenses, you ca

Under new bill, Bigfoot could become California’s “official cryptid”

You might suspect that a one-line bill about Bigfoot that bears the number "666" is a joke, but AB-666 is apparently a serious offering from California Assemblymember Chris Rogers. Rogers represents a California district known for its Bigfoot sightings (or "sightings," depending on your persuasion—many of these have been faked), and he wants to make Bigfoot the "official cryptid" of the state. His bill notes that California already has many official symbols, including the golden poppy (official

Despite recent layoffs, Meta is expanding in India

Meta made headlines last month for announcing plans to cut 5% of its employees, controversially deeming them “low performers.” But the job cuts aren’t holding Meta back from expanding in certain geographic areas. Meta is setting up a new site in the country’s tech hub of Bengaluru (formerly known as Bangalore), multiple Meta employees posted on LinkedIn this month. Meta is currently hiring for 41 positions there, according to its careers webpage, most of which were posted over the last month.

iOS 18.4 will bring Apple Intelligence-powered ‘Priority Notifications’

Apple on Friday released its first developer beta for iOS 18.4, which adds a new “Priority Notifications” feature, powered by Apple Intelligence. The addition aims to help users manage their notifications by prioritizing important alerts and minimizing distractions from less important ones.

Apple Intelligence will analyze which notifications it believes should be shown in this section, but you can still

Nvidia's RTX 5070 Ti vanishes in seconds as supply woes continue

Facepalm: After Nvidia's RTX 5090 and 5080 faced immediate shortages, consumers hoped that the company's new mid-range graphics cards would at least stay in stock for more than a millisecond. Unfortunately, the RTX 5070 Ti sold out just as quickly, and reports suggest that the RTX 5070 and 5060 may face similar supply issues. As the RTX 5070 Ti officially "launched" on February 20, screenshots of storefronts revealed just how quickly every model sold out. Screenshots of Newegg's front page, ta

Sony former exec says the company is "printing money" by releasing PlayStation games on PC

The big picture: Shuhei Yoshida spent more than three decades at Sony, leading the PlayStation project from its early years. Now retired, the BAFTA Fellowship-awarded industry veteran is revealing some of the gaming industry's worst-kept secrets – starting with the significant role played by the PC platform. In a recent interview, Shuhei Yoshida confirmed the "rumors" that everyone in the gaming industry has known for years: Sony is making substantial profits from PC conversions of its PlayStat

Shares of Hims & Hers tumble 23% after FDA says semaglutide is no longer in shortage

Shares of Hims & Hers Health tumbled more than 23% on Friday after the U.S. Food and Drug Administration announced that the shortage of semaglutide injection products has been resolved. Semaglutide is the active ingredient in Novo Nordisk's blockbuster weight loss drugs Wegovy and diabetes treatment Ozempic. Those medications are part of a class of drugs called GLP-1s, and demand for the treatments has exploded in recent years. As a result, digital health companies like Hims & Hers have been pr

Doctors and patients are calling for more telehealth. Where is it?

But doctors are generally allowed to practice medicine only where they have a license. This means they cannot treat patients across state lines unless they also have a license in the patient’s state, and most physicians have one or two licenses at most. This has led to what Ateev Mehrotra, a physician and professor of health policy at the Brown University School of Public Health, calls an “inane” norm: A woman with a rare cancer boarding an airplane, at the risk of her chemotherapy-weakened immu

T-Mobile users beware: New scam tricks customers into returning ‘free’ phones to fraudsters

Edgar Cervantes / Android Authority TL;DR It looks like scammers are posing as T-Mobile reps, offering “free phones” to loyal customers and tricking them into placing real phone orders. Victims receive a phone, and then the scammer contacts them claiming the wrong model was sent. The victim is asked to return the phone, which ends up in the hands of the scammer, leaving the victim with an unpaid installment balance. T-Mobile users, beware. There’s a new, highly convincing scam targeting subs

iPhone 16e benchmark results, RAM, and charging speed revealed

Apple is removing iCloud end-to-encryption features from the UK after government compelled it to add backdoors

Apple is removing the option to enable Advanced Data Protection for iCloud users in the United Kingdom. This feature let users fully protect their data stored in iCloud with end-to-end encryption. However, a recent UK government order forces companies like Apple to put backdoors in its encryption systems. Rather than comply and compromise Advanced Data Protection, Apple is left with no choice but to remove the feature altogether. In a statement to 9to5Mac, Apple said that current users of ADP i

Your Apple Vision Pro is getting a lot better with visionOS 2.4

The Morning After: Apple reveals its new cheapest iPhone. What’s missing?

The price has been bumped up, but so have the specs. If you couldn’t stomach $800 for a new iPhone with Apple Intelligence, don’t worry: Apple just announced the iPhone 16e. At $599, it strikes a balance on specs, which is the soft and cosy way to say it doesn’t have everything. It has a lot, though. With a 6.1-inch screen, it’s a much bigger device than the 4.7-inch iPhone SE, with a notch for FaceID (no more TouchID), USB-C (adios, Lightning) and the company’s A18 processor. There’s also an

Coinbase says Trump’s SEC has ended its enforcement case against the crypto company

Coinbase says that the SEC has agreed to end an enforcement case that accused it of illegally running an unregistered securities exchange. This could signal a major change in how the US government will enforce the crypto market now that Trump is in office. The lawsuit, which was filed during the Biden administration , has long-been considered an attempt to bring the crypto industry under the same investor-protection rules that govern stocks and other securities. Coinbase had been fighting the l

Apple disables iCloud's Advanced Data Protection feature in the UK

Apple users in the UK can no longer access one of the company's most powerful data protection tools, as first reported by Bloomberg. The feature, Advanced Data Protection (ADP), allows iPhone users to add optional end-to-end encryption to a variety of iCloud data. The move comes amid an ongoing dispute between Apple and the UK over a government order that would require the company to build a backdoor to allow British security officials to access the encrypted data of users globally. "ADP protec

Is your phone truly waterproof? Here's what the IP rating tells you

Just how water-resistant is that box filled with electricity? Adrian Kingsley-Hughes/ZDNET I remember a time when you wouldn't dare let water anywhere near a smartphone or power bank, as it would almost certainly mean disaster.

YouTube May Finally Offer a Cheaper Way to Get Rid of Ads

Folk who want to watch their multi-hour-long YouTube documentaries without an ad break every few minutes may finally have a cheaper way to do it. The Alphabet-owned streaming service has long been testing a cheaper ad-less subscription tier called YouTube Premium Lite. If the latest reports can be believed, it may come to fruition in 2025, though it probably won’t offer all the perks of the $14-a-month Premium subscription. The last time we heard about Premium Lite was in October last year. You

Apple Says ‘No’ to UK Backdoor Order, Will Disable E2E Cloud Encryption Instead

Good work, Britain. Owners of Apple devices in the United Kingdom will be a little less safe moving forward as the company pulls its most secure end-to-end (E2E) encryption from the country. The move is in response to government demands there that Apple build a backdoor into its iCloud encryption feature that would allow law enforcement to access the cloud data of any iPhone user around the world. Apple has for many years marketed its products as being the most safe and secure personal electron

This Ethiopian Volcano Just Burped a Staggering Amount of Methane

There’s something odd happening under an Ethiopian national park. Volcanic and seismic activity were on the rise under a volcano named Mount Fentale, but the gas that began spouting out of the ground wasn’t what you’d expect from an impending eruption. Canadian greenhouse gas monitoring company GHGSat said in early February that the amount of methane being emitted from Mount Fentale is “substantial.” When GHGSat began measuring the emissions on January 31, they found that the volcano was spewin

Get Outside Just After Sunset to See Six Planets in a Spectacular Planet Parade

2025 is starting off with a bang for skygazers, with a planet parade now visible in the night sky.
