Speed-coding for the 6502 – a simple example

Usually clocked at 1MHz, with no hardware support for multiplication or division, and limited support for bit shifting, it is often important to take a step back from an algorithm in order to make it do the same thing, hundreds of times faster. Note: this article doesn’t describe any technological breakthrough or extremely clever new way of doing things. It’s just a real-life example using a little part of an algorithm I made, and where at first, I stopped at step 2 instead of going all the way

Bella Ramsey Tells ‘The Last of Us’ Haters to Go Play Their Video Games

The online discourse surrounding The Last of Us season two was entrenched in unwarranted outrage, sparked by outrage over the show’s centering a gay love story and killing off the franchise’s leading man. The trolling, which resulted in the show getting review bombed, of course, is weird considering that both these major plot aspects are also present in Neil Druckmann’s series of Naughty Dog games. Recently Bella Ramsey, the show’s Emmy Award-nominated lead (alongside Pedro Pascal), discussed w

Trump administration’s deal is structured to prevent Intel from selling foundry unit

The Trump administration seems intent on controlling Intel’s ability to make key business decisions around its floundering foundry business unit. Intel’s CFO David Zinsner shared new details about the company’s recent deal with the Trump administration, which gave the U.S. government a 10% equity stake, at a Deutsche Bank conference on Thursday, according to reporting from the Financial Times. The deal was structured in a way to penalize Intel if it spins out its foundry business unit, which m

Web Bot Auth

Web Bot Auth is an authentication method that leverages cryptographic signatures in HTTP messages to verify that a request comes from an automated bot. Web Bot Auth is used as a verification method for verified bots and signed agents. It relies on two active IETF drafts: a directory draft ↗ allowing the crawler to share their public keys, and a protocol draft ↗ defining how these keys should be used to attach crawler's identity to HTTP requests. This documentation goes over specific integratio

How to install TrueNAS on a Raspberry Pi

Now that Joel0 in the TrueNAS community has created a fork of TrueNAS that runs on Arm, I thought I'd give it a spin—on a Raspberry Pi. I currently run an Ampere Arm server in my rack with Linux and ZFS as my primary storage server, and a Raspberry Pi with four SATA SSDs and ZFS as backup replica in my studio. My configuration for these Arm NASes is up on GitHub. I've been looking forward to TrueNAS support on Arm for years, though it seems the sentiment in that community was 'Arm servers aren

Service members deserve the right to repair

“The generator is down, and we don’t have enough ice to continue icing the remains of soldiers killed in action. How much longer, ma’am?” That’s the message I received while deployed to Balad, Iraq, as an Air Force second lieutenant. I was overseeing generators in theater, and the one powering the mortuary facility had failed. The clock was ticking. I didn’t have HVAC expertise or the necessary parts. The only viable backup generator was on the other side of the country. I had two choices: ini

‘Tron: Ares’ Uses Elements From a Decade-Old Script

When Tron: Ares hits theaters in October, it’ll be the end of a 15-year roller coaster ride. The second Tron, Tron: Legacy, was released in December 2010, and almost immediately, talks began about a sequel. In that time, multiple writers (15, in fact), directors, and actors attempted to return to the Grid only to fall short. But now, it’s coming, and it’s very different from what fans expected 15 years ago, though some key elements remain. One of the first writers brought on to pen Tron 3 was D

Intel gets $5.7 billion from Trump deal as White House says details are 'being ironed out'

Intel CFO David Zinser said that the semiconductor giant received $5.7 billion from the U.S. government on Wednesday evening. Zinsner acknowledged the investment on Thursday during an investor conference. The investment is part of the White House's decision last Friday to take a 10% stake in the beleaguered computer chip company. Zinser also signaled the possibility that Intel seeks outside investment for its foundry business. The company reported better-than-expected second-quarter results

This Qi2 battery pack from Anker just made wireless charging essential for me

Anker Nano Power Bank MagGo Slim ZDNET's key takeaways The Anker Nano Power Bank MagGo Slim battery pack is a sleek Qi2 MagSafe charging option that costs $55. It features a 5K capacity battery, a slim profile, and comes in 4 colors. It's a bit pricier than direct competitors, and it won't be for those who want a larger battery.

Honor’s Magic V5 is the thinnest foldable yet, but that’s not why it matters

Posts from this author will be added to your daily email digest and your homepage feed. Honor’s Magic V5 is the thinnest book-style foldable in the world, but you probably couldn’t tell. It’s just 0.1mm thinner — that’s four-thousandths of an inch — than the Oppo Find N5 or Samsung’s recent Galaxy Z Fold 7. If that’s a difference you claim to perceive, then I’m afraid I simply don’t believe you. I’ve put the V5 side by side with the Find N5 and I can barely feel the difference, let alone see i

Don't Want Gemini to Learn About You? How to Turn That New Feature Off

The more you chat with Google's Gemini, the better it will get to know you thanks to a new learning feature in the generative AI chatbot. Gemini has already been able to recall past conversations if you ask it to, but this new functionality will allow it to learn your preferences and interact with you in more personalized ways, Google said. But if you don't want an AI to learn about you, you can turn it off. AI chatbots have seen their memories grow longer this year. Other tools, like OpenAI'

The 5 Healthiest Air Fryer Foods, Hand-Picked by Registered Dietitians

Like refrigerators, ovens or microwaves, air fryers have become a staple in our kitchens. In the form of compact, space-saving devices, these fryers are known for crisping food with less oil, making them a healthier alternative to other cooking methods. "Air fryer cooking delivers the crispy texture we know and love from fried foods, but with far less oil and fat than traditional deep frying," explains Melissa Jaeger, head of nutrition at nutrition tracking app MyFitnessPal. However, despite th

On the screen, Libyans learned about everything but themselves (2021)

The first Hollywood film I watched in a theater was “Star Wars: The Last Jedi,” in 2017 in Tunis — the movie in which Disney definitively ruined the franchise forever. Before that, in Libya, I used to buy pirated movies on CDs, or download them from illegal websites. Even the Libyan government got in on the piracy racket, illegally packaging the Arabic-speaking Disney channel along with 19 others and selling it just for 150 Libyan dinars. I say “just,” but 150 Libyan dinars was around $100 U.S.,

Passenger Assaulted in Viral TikTok Video Sues Southwest Airlines, Blames Seating Plan

Video footage went viral on social media earlier this summer after an intoxicated woman was seen on a Southwest Airlines flight pulling another woman’s hair and shouting abusive things before being subdued and arrested. Now the woman who was attacked has filed a lawsuit against her attacker and named Southwest as a co-defendant, partially blaming the airline’s open seating policy for the confrontation. Leanna Perry, identified as a 32-year-old illustrator from Brooklyn by the New York Post, was

Founder of IRL social media app charged with defrauding investors

The founder of the company behind the IRL social media app was charged with defrauding investors of $170 million in the company's 2021funding round, the Department of Justice said Wednesday. A federal grand jury in the Northern District of California indicted Abraham Shafi, 38 of Hawaii, with wire fraud, securities fraud and obstruction in connection with the scheme, the DOJ said. Shafi was the CEO of Get Together, the parent company of IRL. The company was valued at $1 billion after its 2021

People With Ties to Trump Accused of Carrying Out ‘Covert’ Influence Operations in Greenland

Earlier this year, the Trump administration raised eyebrows and inspired scoffs when it announced it wanted to buy Greenland. Since then, the government has ignored the laughs and continued to pursue its stated objective. Now, a new report from a Danish news outlet alleges that multiple Americans with direct ties to Trump have been engaged in covert “influence operations” aimed at Greenlanders. The purpose of these propaganda efforts is to sow division between the Nordic territory and its parent

Why this $25 ratchet tool beats any multitool or Swiss Army Knife I've ever tested

Adrian Kingsley-Hughes/ZDNET I'm always on the lookout for a now toy -- ahem, I mean tool -- to add to my everyday carry (EDC) gear. New multitools, flashlights, and other cool tools are always on my radar. A few weeks ago, I happened to come across something that, the moment I saw it, I just had to have it. It was one of those gambles: "it might be good, it might be on the way back to Amazon by the end of the day". Also: 10 tiny tools I carry with me everywhere - how they work It turned out

I changed these 12 settings on my Android phone to greatly extend its battery life

Kerry Wan/ZDNET Follow ZDNET: Add us as a preferred source on Google. I've spent large portions of my life looking for ways to extend the battery life on my Android phones. Admittedly, that sounds rather dramatic, but growing up with only budget models meant I was constantly tweaking device settings to squeeze every bit of juice out of their batteries. Thanks to this micromanaging, I successfully pushed the batteries on all my past smartphones to their absolute limit. I don't want to hoard th

Astrophysicists find no 'hair' on black holes

According to Albert Einstein’s general theory of relativity, the behavior of a black hole depends on two numbers: how heavy it is, and how fast it is rotating. And that’s it. Black holes are said to have “no hair” — no features that distinguish them from their fellows with the same mass and spin. With new data, it has started to become possible to test this no-hair conjecture. Astronomers have detected hundreds of signals from colliding black holes over the past 10 years. In these dramatic even

‘The Dark Crystal’ Is Returning to Theaters, Which Isn’t ‘The Dark Crystal’ News We Were Hoping For

Fathom Entertainment is celebrating 70 years of the Jim Henson Company by bringing its cult 1982 film, The Dark Crystal, back to theaters on October 12-13. This is, undoubtedly, good news. Dark Crystal rules. And yet that we could have good Dark Crystal news in the year 2025 and it not be about the incredible Netflix prequel series, The Dark Crystal: Age of Resistance, does make it slightly bittersweet. The Dark Crystal: Age of Resistance was released on Netflix back in 2019, and we think it wa

The Pixel 10 comes with 12GB of RAM, but Google has locked some of it away

Robert Triggs / Android Authority The Google Pixel 10 series has plenty of new features for both fans and newcomers. As is Google’s current direction of travel, many of these focus on new or improved AI tools. However, leaning heavily on AI to power smartphones requires a few changes to how we usually think about running apps. Typically, when we open an app, we expect it to appear within a second or so, with the phone quickly fetching it from storage and loading it into RAM. Larger application

How much RAM do you actually need in 2025? I broke it down for Windows and Mac users

Kerry Wan/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways RAM is an important hardware resource that allows a computer to perform optimally and at fast speeds. Escalating computing demands have made 16GB of RAM the new standard for PCs and laptops if they are to continue performing at their best. Even then, 16GB of memory may not be enough for certain users, so it's important to know when to upgrade. I used to struggle when shopping for a new computer. Ove

South Korea bans smartphones in all middle and elementary school classrooms

South Korean lawmakers have banned smartphones and other smart devices in elementary and middle school classrooms, The New York Times reports. The law goes into effect in 2026. The legislation only outlaws these devices during class hours and there are no stipulations regarding punishment for violators. The law does, however, give principals and teachers the power to stop students from carrying or using a phone on school grounds. Additionally, students are able to use smart devices during emerg

US sanctions fraud network used by North Korean ‘remote IT workers’ to seek jobs and steal money

The U.S. Treasury has sanctioned an international fraud network used by North Korea to infiltrate U.S. companies with hackers posing as legitimate job seekers, agency officials announced Wednesday. The sanctions are the latest action taken by the U.S. Treasury in recent months aimed at combating North Korean government workers from seeking employment at American companies using fake identities and documents to apply for jobs. Once employed, the hackers earn a wage from the company, but also ste

This slim concept phone has a 15,000mAh battery, but one giant drawback

TL;DR Realme has revealed a concept phone with a 15,000mAh battery. The phone is less than 9mm thick and can last for up to five days. The device uses a battery with 100% silicon content, effectively ruling out mass production for now. The advent of silicon-carbon batteries has resulted in many smartphone brands offering bigger batteries than ever before. We’ve already seen HONOR and vivo launch phones with ~8,000mAh batteries in relatively slim designs. Now, realme has revealed a rather impr
