Nullable vs nullable in C# One of the most unfortunate parts of the nullability narrative in C# is the reuse of the T? syntax to denote two completely separate concepts for value types and reference types. This leads to some odd and confusing behaviour. As you may know, nullable value types is a much older concept than nullable reference types. Nullable value types were introduced in C# 2.0, whereas nullable reference types came in C# 8.0. And they’re not the same. Nullable isn’t nullable. Fo
I heard someone say that Bitcoin is dangerous because you could easily make a typo when entering an address, sending money to the wrong person, and have no recourse. There are dangers associated with Bitcoin, such as losing a private key, but address typos are not a major concern. Checksums There are several kinds of Bitcoin addresses. Each is at least 20 bytes (160 bits) long, with at least 4 bytes (32 bits) of checksum. The chances of a typo resulting in a valid checksum are about 1 in 232.

The January wildfires left many scars on the city of Los Angeles, from rubble-reduced homes to torched abandoned vehicles. Though cleanup crews quickly cleared much of the debris, one alarming invisible impact lingered over the city for months, a new study suggests. In late March—more than two months after the flames died out—researchers detected levels of carcinogenic hexavalent chromium (a.k.a. chromium-6) 200 times greater than baseline levels for LA air. If this pollutant sounds familiar, y
Why we like it: Colgate Optic White Pro Series toothpaste is one whitening toothpaste that Dr. Fatima Khan, a dentist in Houston, Texas, recommends. Some of her reasons for recommending it include its trusted brand name and its 5% hydrogen peroxide whitening agent. Unlike other whitening agents that work by removing stains on the surface of the tooth, hydrogen peroxide can get inside the tooth so it whitens intrinsically as well as extrinsically. Sachar also recommends this toothpaste, saying,
Meal kits have evolved dramatically in the 13 years since Blue Apron launched in the US. Today, nine major meal kit services operate across the country, and their convenient dinner packages have become comparatively cheaper and better suited to people with dietary restrictions. Increased competition has brought variety and consumer-friendly makeovers to meal delivery services, but much of the population is still skeptical. In a recent CNET survey of more than 2,600 US adults, most of those who
When it comes to watching horror movies, one of my favorite sub-genres is sci-fi horror. Give me the terror of deep space, futuristic worlds where things have gone terribly awry, and larger-than-life spaceships where the crews are trapped with unspeakable horrors. While Alien might be the most popular movie in this genre, there are some amazing sci-fi horror flicks out there just waiting to be discovered. One of my favorites is Pandorum. Released in 2009, it's is a claustrophobic trip into spac
When DJI announced the Mic 3 just 18 months after the excellent Mic 2, I didn’t really get it. The Mic 2 has been my own go-to wireless microphone (bought with my own money, no less) for over a year now, and it still feels new to me. What could justify yet another iteration so soon? It took about five seconds with the Mic 3 in my hands to understand exactly what DJI was thinking. The transmitter units are dramatically smaller and lighter than those on the Mic 2, so much so that they feel like e
On a Wednesday night in August, hundreds of people gathered in the lobby of Apple Cinemas in central San Francisco. To gain admission to the event, attendees had to say a secret code word to the crew working the door: three giggling children wearing oversize “SECURITY” caps. The throng inside hunted for QR codes on the walls and admired a makeshift art gallery that showcased a collection of paintings, each referencing a famous historical work—Vermeer’s Girl With a Pearl Earring, Munch’s The Scr
I took a deep dive on my hunt for the best greens powders, speaking with dietitians and trying popular brands to uncover whether or not they're worth the money. The health supplement market is booming. Thanks to a 1994 FDA ruling that supplements are food and not medicine, it's also unregulated—people are purchasing products that may or may not work, and which could have almost anything in them. Spoiler alert: Greens powders aren’t harmful, ultimately, but the dietitians I spoke to agreed that
Google’s Phone app is adding “Calling Cards” that let you customize the appearance of contact screens for incoming calls. They’re similar to the Contact Poster feature that iPhone users have had since 2023, allowing Google Phone app users to replace the teeny contact photos that appear when someone is calling you with full-screen images and stylized names. The update is part of Android’s Material 3 Expressive design language overhaul, which Google used to test a revamped Phone app interface in

Lenovo is gearing up to show off its latest products at Europe’s IFA tech tradeshow next week, but leaks may have just given us a first look at what’s being announced. The most notable gadget shared by reputable leaker Evan Blass shows an image of a concept laptop design with a display that rotates between landscape and portrait orientations, which Lenovo has reportedly dubbed “Project Pivo.” Lenovo has a history of making funky laptop concepts — such as the see-through ThinkBook Transparent Di
With 4 million app downloads, Estonia-based startup Vocal Image aims to help people improve their voice and communication skills with AI-powered coaching. But out of its 160,000 active users, it may be its CEO, Nick Lahoika, who best embodies its mission. Lahoika was born in Belarus, didn’t speak English until his relocation to Estonia, and once struggled with speaking anxiety. Yet, he went on to “win a lot of pitch competitions” on behalf of the voice coaching startup, which was inspired by hi

Kerry Wan/ZDNET Follow ZDNET: Add us as a preferred source on Google. Samsung's Galaxy smartphones are some of the best Android phones available today, thanks to their responsive and feature-rich software. But most Samsung phones -- especially the flagships like the Galaxy S25 Ultra, Galaxy Z Fold 7, and Z Flip 7 -- come with over-the-top features that you might not use daily. If your new Galaxy phone isn't lasting an entire day on a single charge, there are ways to make the most of what you
Authors: Marko Kabić, Bowen Wu, Jonas Dann, Gustavo Alonso Abstract In this study we explore the impact of different combinations of GPU models (RTX3090, A100, H100, GraceHoppers - GH200) and interconnects (PCIe 3.0, PCIe 4.0, PCIe 5.0, and NVLink 4.0) on various relational data analytics workloads (TPC-H, H2O-G, ClickBench). We present MaxBench, a comprehensive framework designed for benchmarking, profiling, and modeling these workloads on GPUs. Beyond delivering detailed performance metrics,
You can cut a hole in a cube that’s big enough to slide an identical cube through that hole! Think about that for a minute—it’s kind of weird. Amazingly, nobody could prove any convex polyhedron doesn’t have this property! It’s called ‘Rupert’s property’. Until this week. This week Steininger and Yurkevich proved there is a convex polyhedron that you can’t cut a hole in big enough to slide the entire polyhedron through the hole. It has 90 vertices, and apparently 240 edges and 152 faces. To

Debian 13 “Trixie” introduces an important change to /tmp. Traditionally, it’s been just another filesystem, albeit with some special permissions that allows everyone on the system to use it without being able to remove each other’s files. In Trixie, it’s been moved off the disk into memory – specifically a type of memory called tmpfs. To quote the tmpfs man page: The tmpfs facility allows the creation of filesystems whose contents reside in virtual memory. Since the files on such filesystems
