Graphical Linear Algebra

Applications are open for the ACT Applied Category Theory Research School 2018! And because arithmetic science and geometric science are connected, and support one another, the full knowledge of numbers cannot be presented without encountering some geometry, or without seeing that operating in this way on numbers is close to geometry; the method is full of many proofs and demonstrations that are made with geometric figures. Fibonacci, preface to Liber Abaci (first published 1202, 1228 manuscrip

Our favorite desk accessories for Prime Day

What you have on your desk and in your workspace at home can reveal a lot about you: how you work, what you like to distract yourself with, what kind of toys and other tchotchkes you like to have around you. That is why we have the What’s On Your Desk? series, where we look at how some of our coworkers organize their spaces. It gives us — and you, our readers — a glimpse into the personality of the folks who work here. Out of curiosity, we took a look at some of our past articles to see if any

The Last of Us Part II’s new mode puts the story in chronological order

With season 2 of HBO’s The Last of Us in the books, and with no The Last of Us Part III coming in the immediate future, Naughty Dog has come up with an interesting way to funnel all the attention from the show into the game. The studio has released a new, free patch for The Last of Us Part II Remastered that lets you play the game in chronological order. The mode takes Abby and Ellie’s stories and interleaves them in chronological order rather than the nonlinear story of the original version of

Running a Certificate Transparency log

Hear me out. If you are an organization with some spare storage and bandwidth, or an engineer looking to justify an overprovisioned homelab, you should consider running a Certificate Transparency log. It’s cheaper, easier, and more important than you might think. Certificate Transparency (CT) is one of the technologies that underpin the security of the whole web. It keeps Certificate Authorities honest, and allows website owners to be notified of unauthorized certificate issuance. It’s a big pa

Battling next-gen financial fraud

Synthetic identity fraud now costs banks $6 billion a year, making it the fastest-growing financial crime in the US Criminals are able to exploit personal data breaches to fabricate “Frankenstein IDs.” Cheap credential-stuffing software can be used to test thousands of stolen credentials across multiple platforms in a matter of minutes. And text-to-speech tools powered by AI can bypass voice authentication systems with ease. “Technology is both catalyzing and transformative,” says John Pitts, h

Is it possible to play doom on an oscilloscope using only lissajous figures?

Getting a piece of electronics to run doom (1993) is a classic project in hobby electronics, and so far people have gotten doom to run on pretty much anything, including analog oscilloscopes. However, in all cases that I have seen, the only part of the oscilloscope that is really "running" doom is the CRT display, which is hooked directly to an external computer a la 90's game consoles.Meanwhile, people also have managed to get analog oscilloscopes to display some pretty extraordinary and dynami

Amazon Needs to Clear Dyson V15 Stock Fast, Now at a New Record Low for Prime Day

Dyson has always been the crème de la crème when it comes to cordless stick vacuums and the V15 Detect Plus is one of the latest and most advanced models in their lineup. It has a reputation for having the latest technology and powerful suction force, and the V15 Detect Plus takes cleaning to new levels. Amazon is marking Prime Day with a exclusive Prime member offer that cuts the price to an all-time low of $569, down from its usual $749. That’s even lower than some of Dyson’s older models whi

Artist in Residence on a Satellite

On February 3, 2024, at 11:06 a.m., the first Chinese art satellite, "SCA-1" (The first satellite of the Star Chain of Arts Project), was successfully launched into orbit near the sea area of Yangjiang, Guangdong, using the Long March 3B carrier rocket. The satellite's solar panels deployed normally, and the initial telemetry is normal. Among the thousands of satellites now orbiting above us, including scientific, meteorological, communication, and military satellites, there was a missing catego

New iPhone 17 Pro renders highlight aluminum design, repositioned Apple logo

A new image from Apple leaker Majin Bu provides a new look at the repositioned Apple logo on the upcoming iPhone 17 Pro. Last week we got our first look at what the new Apple logo placement would look like, though this new image provides a much clearer picture. One of the less talked about design elements of the new iPhone 17 Pro design is the fact that Apple will be shifting to a two-tone design of sorts, with an all aluminum frame and camera bump. However, for wireless charging, MagSafe, and

Tennis players criticize AI technology used by Wimbledon

Some tennis players are not happy with Wimbledon’s new AI line judges, as reported by The Telegraph. This is the first year the prestigious tennis tournament, which is still ongoing, replaced human line judges, who determine if a ball is in or out, with an electronic line calling system (ELC). Numerous players criticized the AI technology, mostly for making incorrect calls, leading to them losing points. Notably, British tennis star Emma Raducanu called out the technology for missing a ball th

SUS Lang: The SUS Hardware Description Language

The compiler keeps track of many aspects of your hardware design, and displays them in the editor. Core Philosophy The SUS HDL is meant to be a direct competitor to Synthesizeable Verilog and VHDL. Its main goal is to be an intuitive and thin syntax for building netlists, such that traditional synthesis tools can still be used to analyze the resulting hardware. SUS shall impose no paradigm on the hardware designer, such as requiring specific communication protocols or iteration constructs. In

Dyson, techno-centric design and social consumption

7th July 2025 As a design engineer I’ve spent plenty of time mulling over what ‘good’ design is. The question is complex and is a starting point for reflecting on our role as designers, how design should interact with society and what even constitutes design! I recently visited the Glasgow Zine Festival and picked up a wee zine about one man’s hatred of James Dyson, which has inspired me to put some of my own thoughts on the topic down in words. I'm going to focus on formal design elements but

Amazon Is Going All In For Prime Day, Samsung 990 EVO Plus 2TB SSD Is Cheaper Than Most Budget External SSDs

Prime Day is now Amazon’s biggest shopping day of the year, even surpassing Black Friday, because of its traditionally low prices on everything from technology essentials to daily staples. This year, the deals are especially strong on top sellers by brand favorites like Apple and Samsung, and maybe the best discount is on the Samsung 990 EVO Plus SSD. For users who desire the utmost performance for their laptop or PC, this 2TB SSD can be had for the price of just $139, down from $176, which is

What Is Li-Fi? Here's How Connecting to the Internet May Rely on Light

Yes, you heard that correctly. Connecting to the internet could be as simple as turning on the light. Picture this: Using this technology to connect to the internet promises speeds that will blow Wi-Fi out of the park. The average household requires more and more bandwidth, with users spending an average of 21-plus hours streaming weekly, according to the latest OpenVault report. That makes the promise of Li-Fi convenient. Li-Fi has made plenty of headlines lately, particularly about how it coul

New study offers clues about what makes someone cool

Is there a secret sauce that helps explain why people as different as David Bowie, Samuel L. Jackson and Charli XCX all seem so self-assured and, well, cool? A new study suggests that there are six specific traits that these people tend to have in common: Cool people are largely perceived to be extroverted, hedonistic, powerful, adventurous, open and autonomous. The study, which was published on Monday in the Journal of Experimental Psychology: General, surveyed nearly 6,000 participants from

Inside a Utah desert facility preparing humans for life on Mars

Hidden among the majestic canyons of the Utah desert, about 7 miles from the nearest town, is a small research facility meant to prepare humans for life on Mars. The Mars Society, a nonprofit organization that runs the Mars Desert Research Station, or MDRS, invited CNBC to shadow one of its analog crews on a recent mission. "MDRS is the best analog astronaut environment," said Urban Koi, who served as health and safety officer for Crew 315. "The terrain is extremely similar to the Mars terrain

Mercedes-Benz electric G-Wagen review: king of the off-road

As exciting as it is to see how electric technology redefines automotive transportation, it’s just as exciting to see how it alters what we already have. In the aftermarket, EV-converted restomods are quickly becoming big business. But direct from manufacturers, there’s great potential in electrifying legacy badges by seamlessly blending old design with new technology. Case in point is the 2025 Mercedes-Benz G580 with EQ Technology, better known as the EV Geländewagen (which is German for all-t

Making My Own Hacktoberfest T-Shirts

Between 2014 and 2022, DigitalOcean sent free t-shirts to developers who completed the Hacktoberfest challenge. For entirely sensible reasons related to sustainability and spammy entrants, they stopped doing physical merchandise in 2023. I'm the sort of hip fashionista who only wears free conference t-shirts. Sadly, after several years of constant catwalk modelling, my beloved Hacktoberfest shirts are full of holes. I couldn't find any for sale on eBay or Vinted - so I decided to make my own.

Rust and WASM for Form Validation

In recent years, Rust and WebAssembly have become much more usable for pure backend-style engineers. When I say “pure backend-style”, I mean people who never wrapped their heads around React, SPAs, and all that stuff. This, unsurprisingly, includes me. For a very long time, in order to use WASM you were strongly guided towards using Webpack and a whole array of Node-related tools in order to just get started. These days, luckily, the story has become much more streamlined. In today’s tutorial,

Judge Rules That Newspaper Is Allowed to Search Through Users' ChatGPT Logs

Amid its long-running copyright infringement lawsuit against OpenAI, the paper of record will soon have access to all of OpenAI's user archives — including the stuff that was deleted. As Ars Technica reports, the federal judge presiding over the lawsuit by the New York Times against OpenAI has granted the newspaper and its co-plaintiffs, the New York Daily News and the Center for Investigative Reporting, access to the AI company's logs to see exactly how much copyright was infringed.
