leecoursey··on An algorithmic failure beneath the secret ballot
A Princeton researcher showed that a known flaw in Georgia's ballot scanners, still unpatched in places, lets someone with public records and cheap AI tools work out the order ballots were cast and potentially link them to voters. He recovered the order for nearly 99% of in-person ballots in 114 counties and says secrecy can be broken entirely in small ones.

leecoursey··on Models Are Getting Dumber on Purpose
Are we slowly discovering what evolution already "realized" via optimization of human brains? i.e., procedural knowledge is easier to maintain than a library of facts, and facts can be accessed in external repositories if one knows the procedure for doing so.

leecoursey··on [dead]
A 20-year study involving 2,800 healthy adults aged 65 and older found that those who completed specific computerized speed training, which involved quickly identifying flashing objects, lowered their risk of dementia and Alzheimer’s disease by 25% compared to a control group. Participants in the speed training group initially received five weeks of two weekly sessions, and the group that showed the most benefit also received eight additional “booster” sessions across the following three years. This training, called Double Decision, focuses on improving visual speed, divided attention, and peripheral vision; researchers theorize the reduced risk is due to procedural learning, which drives a lasting, fundamental change in the brain similar to learning a skill like riding a bicycle.

leecoursey··on Axial Flux Motor Powers Supercars to New Heights
Electric motor company YASA, acquired by Mercedes-Benz in 2021, is transitioning its breakthrough high-density axial-flux technology from exclusive hybrid supercars to mass-market performance vehicles. The company’s latest prototype motor generates a peak 750 kilowatts (1,005 horsepower) while weighing only 12.7 kilograms (27.9 pounds). This yields a power density of 59 kilowatts per kilogram, which the company claims is an unofficial world record and approximately three times the efficiency of current leading radial-flux designs, including those used by Tesla. Daimler is actively retrofitting a factory in Berlin to produce up to 100,000 of these compact, powerful motors annually for deployment in upcoming Mercedes-AMG electric vehicles, marking the first time this high-performance technology will be used in mass production.
leecoursey··on In 1995, a Netscape employee wrote a hack in 10 days that now runs the Internet
JavaScript, which runs on an estimated 98.9 percent of all websites globally, is celebrating the 30th anniversary of its initial announcement. The programming language originated from a joint press release issued by Netscape Communications and Sun Microsystems in May 1995, following an intensive 10-day sprint by Netscape engineer Brendan Eich who developed the foundational working prototype. Netscape intended the design to be a lightweight scripting tool that would appeal to web designers and non-professional programmers, allowing them to add interactive elements to webpages. JavaScript quickly grew past its browser origins and now consistently ranks among the most widely used languages in the world, powering mobile applications, server infrastructure, desktop software, and embedded systems.
leecoursey··on WhatsApp API flaw let researchers scrape 3.5B accounts
Security researchers successfully compiled a database containing 3.5 billion active mobile phone numbers and associated personal information from WhatsApp by exploiting a major security flaw in the platform’s contact-discovery application service. The vulnerability, stemming from a critical lack of usage controls, allowed the team to check over 100 million potential numbers per hour from a single server without detection or throttling. The collected data included phone numbers, public “about” text, device information, and 77 million profile images from a test of US users. Following the responsible disclosure of this failure, the company added traffic-limiting safeguards to the service to prevent future bulk collection efforts.
leecoursey··on Brain-wide representations of prior information in mouse decision-making
Mice were trained to indicate the location of a visual grating stimulus, which appeared on the left or right with a prior probability alternating between 0.2 and 0.8 in blocks of variable length. We found that mice estimate this prior probability and thereby improve their decision accuracy. Furthermore, we report that this subjective prior is encoded in at least 20% to 30% of brain regions that, notably, span all levels of processing, from early sensory areas (the lateral geniculate nucleus and primary visual cortex) to motor regions (secondary and primary motor cortex and gigantocellular reticular nucleus) and high-level cortical regions (the dorsal anterior cingulate area and ventrolateral orbitofrontal cortex). This widespread representation of the prior is consistent with a neural model of Bayesian inference involving loops between areas, as opposed to a model in which the prior is incorporated only in decision-making areas. This study offers a brain-wide perspective on prior encoding at cellular resolution, underscoring the importance of using large-scale recordings on a single standardized task.

leecoursey··on The First Diagnostic Immunome
A recent study published in Science demonstrates the potential of sequencing B and T cell receptors for diagnosing autoimmune conditions. The study, which analyzed data from nearly 600 individuals, utilized machine learning and A.I. models to identify patterns in B and T cell receptors associated with specific diseases. The results, with an area under the receiver operating characteristic curve (AUROC) of 0.986, suggest that this approach could revolutionize autoimmune disease diagnosis, potentially replacing current expensive and time-consuming tests.

Interesting. The word "calendar" does not appear on the Apple Invites announcement webpage. Does it integrate with Calendar? If not, I'm not sure how well this will fit into my daily routine - I definitely need events to appear on my calendar, not (just) in a dedicated "Events" app.

leecoursey··on Spotify has shut down several API endpoints
> Most people writing small scripts were probably using an API key with development mode.

Yep, me included. Since my apps were never meant as anything more than utilities for myself, I never applied for extended access. Nevertheless, I used these tools multiple times a day, especially for sorting and filtering playlists by audio features such as energy and valence. Now, apparently, they will never work again. I'm sure there are plenty of other hobbyists in the same boat.

leecoursey··on Nanoparticles Engineered to Neutralize Covid
Researchers from the IBB-UAB have developed nanoparticles capable of trapping and neutralizing SARS-CoV2 virus particles. These nanoparticles, composed of three proteins, can be used to manufacture antiviral materials such as wastewater and air filters, and could be redesigned to target other pathogens. The nanoparticles’ red fluorescence makes them easier to track and localize, enhancing their versatility in various applications.
