Object-oriented design patterns in C and kernel development

My scheduler operations implementation A benefit of working on your own operating system is that you’re free from the usual "restraints" of collaboration and real applications. That has always been a major factor in my interest in osdev. You don’t have to worry about releasing your program, or about critical security vulnerabilities, or about hundreds of people having to maintain your code.

The Top Diseases We Choose to Stay Ignorant About, According to Scientists

The old adage “ignorance is bliss” feels especially fitting when it comes to healthcare. In fact, new research reveals that one in three people avoids—or is likely to avoid—medical information. In a study published in the Annals of Behavioral Medicine earlier this month, researchers investigated data from 92 studies involving 564,497 participants from 25 countries. Despite the fact that successful treatment often depends on early detection, their results indicate that many people are reluctant

SpaceX Starship Finally Pulls Off a Successful Test Flight

Elon Musk and his SpaceX team can breathe a collective sigh of relief.

Android 16 will soon let you know which apps use Advanced Protection features (APK teardown)

Mishaal Rahman / Android Authority TL;DR Android 16’s Advanced Protection is getting new useful features. We’ve discovered an under-development interface that will list all the apps that are aware of Advanced Protection being turned on. Besides Google apps, the feature will also include third-party apps that can access the state of Advanced Protection. With the rollout of Android 16 earlier this year, Google introduced an “Advanced Protection” mode that enables high-security features on Andr

Wahoo Kickr Run Review: a (Mostly) Screen-Free Treadmill

Ask any serious runner and they’ll tell you that treadmills are usually the bane of their existence. Alas, for folks who don’t live in Mediterranean climates, they’re a necessary winter evil that keeps us fitter in the off-season, but not necessarily happier. The no-frills design of the Wahoo Kickr Run, plus a magical mode that allows it to track your pace without touching a button, is what makes it the most real-pavement-seeming treadmill I have ever run on. I’m admittedly 20 pounds heavier th

AI comes for the job market, security, and prosperity: The Debrief

I was struck by her pessimism, which she told me was shared by friends from California to Georgia to New Hampshire. In an already fragile world, one increasingly beset by climate change and the breakdown of the international order, AI looms in the background, threatening young people’s ability to secure a prosperous future. It’s an understandable concern. Just a few days before our drive, OpenAI CEO Sam Altman was telling the US Federal Reserve’s board of governors that AI agents will leave ent

Voice recording on Nothing Phone 3’s Essential Space gets a due upgrade

Ryan Haines / Android Authority TL;DR Nothing has updated the voice recorder functionality in Essential Space. With this update, the voice recordings will not have complete transcriptions instead of just summaries. The update is limited to Nothing Phone 3 and has yet to arrive on the Phone 3a, which offers similar summarization functionality for voice notes. The Nothing Phone 3 may stop short of being the perfect flagship, but it has some unique and nifty elements. One of them is Essential S

This 16-inch Acer with an OLED screen has no business being this good for the price

Acer Swift 16 AI ZDNET's key takeaways The Acer Swift 16 AI is regularly priced at $1,250. Its 16-inch OLED display, well-designed lightweight form, and marathon battery work together to create a laptop that feels more premium than its price would suggest. Its speakers, however, leave much to be desired, and it has its fair share of bloatware. $1,249.99 at Best Buy Follow ZDNET: Add us as a preferred source on Google.

F-35 pilot held 50-minute airborne conference call with engineers before crash

A US Air Force F-35 pilot spent 50 minutes on an airborne conference call with Lockheed Martin engineers trying to solve a problem with his fighter jet before he ejected and the plane plunged to the ground in Alaska earlier this year, an accident report released this week says. The January 28 crash at Eielson Air Force Base in Fairbanks was recorded in a video that showed the aircraft dropping straight down and exploding in a fireball. The pilot ejected safely, suffering only minor injuries, bu

This Hidden iPhone Feature Could Help Protect Your Eyes

SpaceX's Starship deploys its payload for the first time

SpaceX has successfully launched the Starship for its 10th test flight after it was delayed a couple of times due to weather conditions and other issues. This time, the company was able to achieve its objectives without the vehicle and its booster exploding mid-test. One of those objectives was deploying Starship's payload for the first time ever. If you'll recall, Starship exploded during its ascent stage in the company's seventh and eighth test flights. The vehicle made it to space for its nin

Starship Nails 10th Test Flight, Putting SpaceX Back on Track

Following a string of unsuccessful flights, SpaceX managed to pull off its most successful test in months, with Starship fulfilling a number of key milestones. It was a good day for SpaceX. The megarocket blasted off on time, leaving the Starbase launch mount at 7:30 p.m. ET. Stage separation went off without a hitch, with the Super Heavy booster landing in the ocean as planned nearly 7 minutes into the mission. Second engine cutoff (SECO) occurred a few minutes later, and Starship began to cru

Taylor Swift Is Engaged. Her Post Smashed an Instagram Record

Nobody is shaking this off: Pop superstar Taylor Swift and Kansas City Chiefs tight end Travis Kelce announced their engagement on Instagram on Tuesday, and the likes exploded like pyrotechnics at a concert. The post broke Instagram's record for reposts, even though, to be fair, reposting just started on Instagram in August. Still, the post hit 1 million reposts in less than 6 hours and earned 14 million likes in just the first hour. By Tuesday evening, it had topped 21.2 million likes. "Your E

SpaceX notches major wins during 10th Starship test

SpaceX’s massive Starship rocket lifted off on its 10th test flight Tuesday evening, hitting two long-sought milestones and putting an end to a string of failures. The 403-foot vehicle lifted off from Starbase, SpaceX’s launch facility and recently incorporated city, at 7:30 p.m. ET after two scrubs earlier this week. The rocket ascended on 33 methane-fueled Raptor engines before separating around three minutes after liftoff. On descent, the Super Heavy booster tested out a new maneuver: inten

Verily is closing its medical device program as Alphabet shifts more resources to AI

In Brief Alphabet’s life sciences arm Verily laid off staff and eliminated its entire devices program Monday. CEO Stephen Gillett announced the “difficult decision” to wind down the program in a staff memo, according to Business Insider. “Over the years, Verily has built a legacy in developing world-class, innovative medical devices,” Gillett wrote, noting that the “path forward requires difficult decisions” as Verily refocuses on AI and data infrastructure. The move continues Alphabet’s agg

Google to verify all Android devs to block malware on Google Play

Google is introducing a new defense for Android called ‘Developer Verification’ to block malware installations from sideloaded apps sourced from outside the official Google Play app store. For apps on Google Play, there was already a requirement for publishers to provide a D-U-N-S (Data Universal Numbering System) number, introduced on August 31, 2023. Google says this has had a notable effect in reducing malware on the platform. However, the system didn’t apply to the vast developer ecosystem

SpaceX Suddenly Seems Pretty Terrified to Launch Starship After Long String of Super Expensive Explosions

For years, SpaceX CEO Elon Musk has been stridently glib when his rockets explode during tests, quipping that the blasts were "just a scratch," a "minor setback," or a "rapid unscheduled disassembly." He's still deploying these jokey ripostes, but there's reason to believe the walls may be starting to close in for SpaceX's efforts on Starship, as more and more of the ultra-expensive spacecraft fail in spectacular public view. The issue is that he's bet the future of the company on the massive

Emergency help for low blood sugar

Most people with type 1 diabetes inject insulin to prevent their blood sugar levels from getting too high. However, if their blood sugar gets too low, it can lead to confusion, seizures, and even death. To combat this hypoglycemia, some patients carry syringes of glucagon, a hormone that stimulates release of glucose. Now MIT engineers have developed an alternative that could work even when people don’t realize they are becoming hypoglycemic. It could also help during sleep, or for children who

‘Bubbles’ turn air into drinkable water

COURTESY OF THE RESEARCHERS In the researchers’ prototype device, a half-square-meter panel of the hydrogel is enclosed in a glass chamber coated with a cooling polymer film. When the vapor captured by the textured material evaporates, the bubbles shrink down in an origami-­like transformation. The vapor then condenses on the glass, where it can flow out through a tube. The system runs entirely on its own, unlike other designs that require batteries, solar panels, or electricity from the grid.

Reimagining sound and space

“It would be very difficult to teach biology or engineering in a studio designed for dance or music,” Jay Scheib, section head for Music and Theater Arts, told MIT News shortly before the building officially opened. “The same goes for teaching music in a mathematics or chemistry classroom. In the past, we’ve done it, but it did limit us.” He said the new space would allow MIT musicians to hear their music as it was intended to be heard and “provide an opportunity to convene people to inhabit the

When to Stream 'South Park' Season 27, Episode 4

Comedy Central Predicting what will happen in a South Park episode is hard, but anticipating when a new installment will stream might be even tougher. The hit satirical series had its season 27 premiere date pushed by two weeks and then announced its second installment would drop two weeks after the first. Since then, it's become customary for new episodes to air every other week. While we don't have additional details on what the next South Park will entail, another aspect of the show is mor

US‘s spike in electricity use is slowing down a bit

On Tuesday, the US Energy Information Agency released its latest data on how the US generated electricity during the first six months of 2025. The data suggests the notable surge in power use is flattening out a bit compared to earlier in the year, with the growth in coal use falling along with it. And despite the best efforts of the Trump Administration, the boom in solar power continues, with solar looking poised to pass hydroelectric before the year is out. Growing, but moderating For the l
