A favicon can be used for steganography by hiding data in its pixels, which the browser interprets as colors. This allows storing small amounts of data, like HTML, in a tiny image.
Data compression is the art of reducing the number of bits needed to store or transmit data, and it can be either lossless or lossy, with lossless compression being reversible and lossy compression discarding unimportant data. The best compression ratio is achieved by understanding the data to be compressed and using a model to estimate its probability distribution, with the goal of assigning ...
The colors that exist in the real world but can't be shown on digital screens are mostly cyans, which are poorly reproduced by screens and LED lighting, but can be seen in nature, particularly in forests, water, and bird feathers. These colors are often created by natural processes that filter light, such as repeated reflections and transmissions through leaves and water, or by the physical ...
The concept of instances in social media is a category error, as it's a Mastodon-brained concept that doesn't apply to atproto, which separates hosting and apps. Decentralization in atproto is achieved by swapping hosting or making new apps, unlike Mastodon where decentralization is measured by the number of instances.
The 3-30-300 test measures a city's tree cover by ensuring every home has a view of at least three trees, 30% tree cover in the neighbourhood, and a park within 300 meters. The test is simple but hard to achieve, with only 14% of Europeans living in areas meeting all three criteria and most cities failing to meet the 30% tree cover requirement.
Neuroscientist Oswald Steward won the 2026 Kavli Prize in Neuroscience for discovering that neurons manufacture proteins near synapses, reshaping neuroscience and potentially leading to new treatments for neurological disorders. This discovery, made over four decades ago, has established the importance of local protein synthesis within neurons and is fundamental to learning, memory, and brain ...
The client-observed mean request time varies with c, asymptotically approaching one second as c increases. This is because the time spent in queue approaches zero as the number of servers increases.
Hyundai is buying SoftBank's remaining 9.65% stake in Boston Dynamics for $325 million, gaining full control of the humanoid robotics company. This move will allow Hyundai to deploy Boston Dynamics' robots in its own factories, starting with the electric Atlas robot at its Georgia plant by 2028.

An experimental satellite has mapped GPS jamming across Europe and the Middle East from space, revealing widespread signal degradation. The data suggests that satellites in low Earth orbit are vulnerable to jamming, affecting their performance and safety.
Oracle engineer Lois Foltan confirmed that JEP 401: Value Classes and Objects will be integrated into the main OpenJDK repository and target JDK 28. The feature allows programmers to declare value classes and objects that can be optimized for performance, enabling density and locality in memory, and is currently in preview mode.
Major AI labs are skeptical of endless parameter count and training data scaling due to limitations and hallucination issues in large models. Smaller models like GLM-5.2 are showing comparable performance to much larger models like GPT-5.5 and Fable 5, indicating actual intelligence has plateaued.
Bobby Prince, a renowned composer and sound designer, passed away on June 16, 2026, leaving behind a legacy in the video game industry. He is survived by his wife Connie, children, and grandchildren, and will be remembered for his kindness, humor, and love.
The history of soccer arcade games spans decades, from early pinball and video games in the 1950s and 1970s to modern 3D titles like Virtua Striker in the 1990s and 2000s. Various companies, including Sega, Taito, and Konami, have released numerous soccer arcade games over the years, with some titles becoming classics and influencing the genre.
In 1969, British camera operators went on strike over pay, turning color cameras to black-and-white, causing TV chaos. The strike led to a unique situation with the TV show Upstairs/Downstairs, with three versions of the first episode.
An operational NAND gate and perceptron were built in Age of Empires II using the game's scenario editor, utilizing goats as signal carriers and rails to represent bits. The circuits use XNOR, AND, and OR gates to perform computations, with the environment serving as coding.
In philosophy of mind, “mental causation” means mental entities have causal effects, especially physical ones. If physicalism is true, then physical effects are explainable in terms of physical causes (or at least, fundamental physical laws), needing no recourse to causation by anything that is not in fundamental physics. This is the “causal exclusion principle” explicated by Jaegwon Kim (and ...
The Ahmes papyrus contains a table of Egyptian fraction representations of fractions of the form 2/n for odd integers n. The Egyptians used a table of these representations to calculate other fractions by doubling and adding 1.
Arch Linux's AUR was subjected to a sustained attack where attackers created new accounts, adopted orphaned packages, and pushed malicious updates. The attack affected over 1,500 packages, with the attackers using various tactics to evade detection.
Software efficiency is not a priority due to abundance of resources and other business demands. Memory usage has not significantly changed in 20 years, with most users not noticing or complaining about it.
The user designed and built a backyard deck for their house, creating 9 detailed drawings to obtain a building permit and following local building codes. The project took 10 months to complete, with the user learning and adapting as they went, and the deck has held up well over the past 9 years with proper maintenance.
A researcher left Google DeepMind after nearly 9 years to join Anthropic, thanking the team for their support and learning experience. They expressed gratitude for the opportunity to lead the AlphaFold team and look forward to future discoveries at Google DeepMind.
Arabic script has problematic digital representation due to its development in pen and ink, and the movable type printing technology that was not well-suited for it. This led to issues with encoding, searching, and displaying Arabic text on computers.
The Open Courts Act of 2026 aims to eliminate PACER fees and modernize federal court filing systems, improving public access and cybersecurity. The bill is supported by EFF and other organizations, seeking to make court records easier to find and understand.
To become a successful researcher, you need to combine reading and building skills, and be willing to put in the time and effort required. A good researcher stays open-minded, refuses to let ego cloud their judgement, and is willing to learn from failure.
A researcher is conducting independent robotic manipulation research on a tabletop setup with a single industrial-grade robot arm, two cameras, and teleoperation, aiming to test the hypothesis that a single person can achieve meaningful results with a budget of €10,000. The setup includes a UFACTORY xArm Lite 6 robot arm, Intel RealSense D405 wrist camera, and Logitech C920 webcam, with a ...
Starfront Observatories in Rockwood, Texas, offers ultra-dark skies for astrophotographers to control their telescopes remotely. Owner Bray Falls hosts 550 telescopes, allowing users to access them from anywhere for as little as 99 dollars a month.
The plan is to drive a huge motorized banana car around the world, meeting people and selling merchandise to fund the trip. A partner is needed for filming, editing, and uploading videos, with a 50/50 split on resulting income.
