“Dynamic programming” is not referring to “computer programming”

When seeing the phrase “dynamic programming” in an algorithms class or leetcode study guide, the first question people ask is “what does ‘dynamic’ mean in this context?”. The key question is instead “what does ‘programming’ mean in this context?”, because it does not mean “computer programming”. Instead it refers to, as the Oxford English Dictionary puts it, programming. n. 4. Planning carried out for purposes of control, management, or administration. So really, it’s closer to “TV programmi

UK backing down on Apple encryption backdoor after pressure from US

Sir Keir Starmer’s government is seeking a way out of a clash with the Trump administration over the UK’s demand that Apple provide it with access to secure customer data, two senior British officials have told the Financial Times. The officials both said the Home Office, which ordered the tech giant in January to grant access to its most secure cloud storage system, would probably have to retreat in the face of pressure from senior leaders in Washington, including Vice President JD Vance. “Th

Dia launches a skill gallery, Perplexity to add tasks to Comet

AI-powered browsers are nowhere near the easy future they promise, when they would be able to do complex multi-step tasks for you. However, the makers of these browsers are trying to make users’ lives easier by adding a way to easily repeat some prompts for the tasks they frequently perform. The Browser Company’s new Dia browser already has a skills feature, which lets users ask the browser to execute a command or create a code snippet based on a prompt. For instance, you could ask the browser

Microsoft Sharepoint server vulnerability puts an estimated 10,000 organizations at risk

A major zero-day security vulnerability in Microsoft's widely used SharePoint server software has been exploited by hackers, causing chaos within businesses and government agencies, multiple outlets have reported. Microsoft announced that it had released a new security patch "to mitigate active attacks targeting on-premises [and not online] servers," but the breach has already effected universities, energy companies, federal and state agencies and telecommunications firms. The SharePoint flaw i

Ryanair may increase commission to staff identifying oversized cabin bags

Ryanair has said that in a bid to "eliminate the scourge" of passengers bringing oversized baggage to the boarding gate, the airline is considering increasing the commission it pays staff for identifying them. Currently Ryanair employees are paid around €1.50 for every oversized cabin bag that they identify, and passengers are charged additional fees if their bag is deemed to be too large to bring on-board the plane. According to the airline's policy, passengers who bring cabin luggage - measu

Bright Fireballs in the Skies: Catch the Perseids Meteor Shower This Week

Skygazers have a lot to look forward to over the next month. A couple of dueling meteor showers are gracing the skies later this month, and they will be joined by perhaps the most popular meteor shower of the year: the Perseids meteor shower. Perseids are known for their bright fireballs and plentiful meteors. The show started on July 17, and will run through Aug. 23. The reason the Perseids meteor shower is so popular is twofold. First, it takes place in the summer, so going outside and watch

I’m Revisiting All of the Naked Gun Movies Before the Reboot. Here’s How You Can, Too

Growing up, the Naked Gun series was a staple in my household. I rented the movies so regularly that my parents gave me the trilogy on DVD for Christmas one year. These days, it’s easier to revisit old favorites through streaming services, but that box set still sits proudly in my media drawers. Even today, I find the straight-faced humor gut-bustlingly hilarious. While headliner Leslie Nielsen starred in some serious films like Forbidden Planet, The Poseidon Adventure and Prom Night, showcasing

It’s “frighteningly likely” many US courts will overlook AI errors, expert says

Order in the court! Order in the court! Judges are facing outcry over a suspected AI-generated order in a court. Fueling nightmares that AI may soon decide legal battles, a Georgia court of appeals judge, Jeff Watkins, explained why a three-judge panel vacated an order last month that appears to be the first known ruling in which a judge sided with someone seemingly relying on fake AI-generated case citations to win a legal fight. Now, experts are warning that judges overlooking AI hallucinati

The Next Thing You Smell Could Ruin Your Life

After my birth, my mother became allergic to the world. That’s the only way I knew how to put it. So many things could set her off: new carpeting, air fresheners, plastic off-gassing, diesel. Perfumes were among the worst offenders. On top of that, she developed terrible food allergies. The sound of her sniffling became the chorus of my childhood. Some days she couldn’t get out of bed. I’d peek into her darkened room and see her face pinched in discomfort. Her joints ached, her head swam. Docto

New zero-day bug in Microsoft SharePoint under widespread attack

The U.S. federal government and cybersecurity researchers say a newly discovered security bug found in Microsoft’s SharePoint is under attack. U.S. cybersecurity agency CISA sounded the alarm this weekend that hackers were actively exploiting the bug. Microsoft has not yet provided patches for all affected SharePoint versions, leaving customers across the world largely unable to defend against the ongoing intrusions. Microsoft said the bug, known officially as CVE-2025-53771, affects versions

Indian crypto exchange CoinDCX confirms $44 million stolen during hack

India’s largest crypto exchange CoinDCX has confirmed that one of its internal operational accounts was compromised in a recent security breach, allowing the hackers to make off with millions in crypto. On Saturday, CoinDCX co-founder and CEO Sumit Gupta disclosed in a post on X that an internal account “used only for liquidity provisioning on a partner exchange” was compromised during the hack. The executive assured that the incident did not affect customer funds and that all its customer asse

AI companies have stopped warning you that their chatbots aren’t doctors

“Then one day this year,” Sharma says, “there was no disclaimer.” Curious to learn more, she tested generations of models introduced as far back as 2022 by OpenAI, Anthropic, DeepSeek, Google, and xAI—15 in all—on how they answered 500 health questions, such as which drugs are okay to combine, and how they analyzed 1,500 medical images, like chest x-rays that could indicate pneumonia. The results, posted in a paper on arXiv and not yet peer-reviewed, came as a shock—fewer than 1% of outputs fro

The Galaxy Z Fold 7 is doing something no Galaxy Fold has done before

C. Scott Brown / Android Authority TL;DR The Samsung Galaxy Z Fold 7 is apparently receiving more pre-orders than the Galaxy Z Flip 7 in Korea. This is reportedly the first time the Fold model has been more popular than the Flip device. Samsung’s newest Fold offers a super-thin and light design, larger screens, and a powerful Snapdragon 8 Elite chip. Samsung’s Galaxy Z Flip series has traditionally been its most popular foldable phone, accounting for most pre-orders and sales over the years.

This clever feature from Apple’s next iPad is something Android tablets also need

Aamir Siddiqui / Android Authority TL;DR Apple’s upcoming iPad Pro M5 will reportedly include two front cameras — one on the landscape edge and another on the portrait edge. The change will allow users to better use both portrait and landscape orientations for selfies or calls. Android tablets should also adopt this approach for its practical benefits. Most big launches are done for this year, but we still have two heavyweights to look forward to in the coming months. Google will launch the

British government set to back down on secret iCloud backdoor after US pressure

We learned earlier this year that the British government had secretly ordered Apple to create a backdoor into encrypted data for all iCloud users worldwide. Specifically, it wanted a way to see personal data protected by Apple’s introduction of Advanced Data Protection (ADP), which extended end-to-end encryption to almost all iCloud data, meaning not even the iPhone maker could access it. Apple has been fighting the secret order in secret court hearings, but it now appears that the US governmen

Is your house power-starved? Why the extra juice might be worth the squeeze

BlackJack3D/Getty The hair dryer routinely trips the breaker and kills power to the second floor. The kitchen lights dim when you run the microwave. The air conditioner can only cool one room at a time on a sweltering night. You don't have adequate power in your house to support your daily needs; we've all been there. These examples might be nostalgic for some, but if you can relate in your current living situation, you might be stuck at a CORE level 1 power-constrained state. Beyond the inco

Debugging Bash Like a Sire (2023)

Many engineers have a strained relationship with Bash. I love it though, but I’m very aware of it’s limitations when it comes to error handling and data structures (or lack thereof). As a result of these limitations I often see Bash scripts written very defensively that define something like: set -euxo pipefail These are bash builtin options that do more or less sensible things. e: Exit immediately when a non-zero exit status is encountered u: Undefined variables throws an error and exits t

Perl Versioning Scheme and Gentoo

The Gentoo Perl Versioning Scheme A common observation/confusion people have is that the versions used on Perl related things in Gentoo don't directly correspond to upstream versions. This is because Upstream uses 2 different schemes, and one of those schemes is fundamentally incompatible with Gentoos. The Problem In most people's mind, this is how version numbers sort: 1.0 1.1 1.5 1.10 1.15 1.20 1.45 This is because you read . as a delimiter for multiple integers. However, in Perl, those

Life Without Screens: This Camp Is a Teen’s Worst Nightmare

Summer. For teens not at work, it’s hot, it’s boring, and it’s an ideal time to close the door and spend about every waking moment watching, playing, texting, streaming—anything but talking—on the phone. With almost half of teenagers in the US saying they’re online almost constantly, the adults in their lives are growing more desperate to drag them off. Families are establishing screen-free zones in their homes, states are banning phones in schools, and a new kind of summer camp has emerged: dig

The Demise of China’s Hottest Online Shopping Craze

During the height of the pandemic, a unique kind of online shopping became one of the hottest trends in China’s tech industry. Called “community group buying,” it allowed consumers to save money on everything from apples to iPhones by placing bulk orders together with their friends and family. The model, which was kind of like Groupon meets Instacart, proved especially popular for groceries. But now, China's community group-buying platforms are vanishing one by one. Late last month, Meituan, th

Mark Zuckerberg Is Expanding His Secretive Hawaii Compound. Part of It Sits Atop a Burial Ground

As a child, Julian Ako would visit his maternal great-grandfather’s home near Pilaa Beach in Kauai, Hawaii, where he and his family would gather edible fungi that grow on kukui trees and collect seaweed and fish from the reef. For about a decade, that land has belonged to Meta CEO Mark Zuckerberg, who is constructing a massive compound at an estimated cost that exceeds $300 million. WIRED can now reveal that Zuckerberg’s property is atop a burial site: Ako’s great-grandmother and her brother we

UK wants to weasel out of demand for Apple encryption back door

The UK government is reportedly set to back down from its battle with Apple to obtain back door access to secure user data protected by the company’s iCloud encryption. Victory hasn’t come through the courts, or government figures changing their minds on privacy matters, but thanks to ongoing pressure from the US during the two countries’ trade talks. Multiple unnamed UK officials told the Financial Times that the UK government is working on a way out. “The Home Office is basically going to hav
