Self-Supervised Learning for Videos
Self-supervised learning has emerged as a good alternative to supervised learning in recent years. It has been shown to beat Supervised Learning on Image Classification benchmarks and is a great option in cases where annotating/labeling is too expensive. However, its impact and performance on videos still need to be investigated since videos have an inherent […]
Don’t obsess over tax and legal structures
Software engineers like optimizing things. It’s easy to nerd snipe them with something that looks like a well defined optimization problem with a few variables and is actually a big complicated mess of badly defined and contradictory almost-facts. This means that many people starting out get obsessed over tax structures. What kind of legal entity […]

Revisiting the Classics: Jensen’s Inequality (2023)
There are a few mathematical results that any researcher in applied mathematics uses on a daily basis. One of them is Jensen’s inequality, which allows bounding expectations of functions of random variables. This really happens a lot in any probabilistic arguments but also as a tool to generate inequalities and optimization algorithms. In this blog […]
How to Build a 50K Ton Forging Press
Alcoa 50,000 ton forging press. In the late 1940s and early 1950s, a revolution took place in American military aircraft design. The invention of the jet engine made it possible for aircraft to fly far higher and faster than ever before. While the fastest propeller-driven aircraft of World War II topped out at slightly less […]
A 4096 channel event-based multielectrode array with asynchronous outputs
Abstract Bio-signal sensing is pivotal in medical bioelectronics. Traditional methods focus on high sampling rates, leading to large amounts of irrelevant data and high energy consumption. We introduce a self-clocked microelectrode array (MEA) that digitizes bio-signals at the pixel level by encoding changes as asynchronous digital address-events only when they exceed a threshold, significantly reducing […]
“YOLO” is not a valid hash construction
By Opal Wright Among the cryptographic missteps we see at Trail of Bits, “let’s build our own tool out of a hash function” is one of the most common. Clients have a problem along the lines of “we need to hash a bunch of different values together” or “we need a MAC” or “we need […]
Degas: Detailed Expressions on Full-Body Gaussian Avatars
DREAMS Avatar Dataset We propose DREAMS Avatar Dataset, including multi-view captures of 6 subjects. Each subject performs two sequences. The first sequence is of standard body motions and required facial expressions including smile, laugh, angry, surprise, etc,. The second sequence is a freestyle. Sequence 1 – render by DEGAS C1-replay Sequence 2 – render by […]
“Something has gone seriously wrong,” dual-boot systems warn after MS update
Enlarge Getty Images Last Tuesday, loads of Linux users—many running packages released as early as this year—started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: “Something has gone seriously wrong.” The cause: an update Microsoft issued as part of its monthly patch release. It was […]
Rod McKuen Was the Bestselling Poet in American History. What Happened? (2022)
n On April 29, 1969, Carnegie Hall was sold out. The artist who filled the fabled performance hall wasn’t a symphony orchestra, or a Broadway belter, or a jazz star. It wasn’t a rock band or a folk singer or any hero of the counterculture taking the stage just a few months before Woodstock. On […]
