The Illinois General Assembly is currently considering a bill, sponsored by Senator Donald P. DeWitte, that would allow public bodies, such as cities and school districts, to withhold information from Freedom of Information Act (FOIA) requests by keeping it in databases. Illinois has a strong FOIA statute that grants public access to most information held by public bodies, requiring them to respond to requests within 5 days. However, the law has limitations, such as not compelling public bodies to create new records

The author discusses two claims related to using patch diffing and document ranking for identifying N-day vulnerabilities in software security. They demonstrated at RVAsec '24 that listwise document ranking can effectively locate functions in patch diffs that address vulnerabilities specified in security advisories. This approach reframes the problem as ranking diffs by relevance to the advisory rather than requiring specialized security knowledge. The author mentions that document ranking techniques can also aid in other offensive security tasks, such as targeting fuzzing efforts and identifying potential injection

A recent study published in JAMA indicates a correlation between newly minted doctors' scores on medical board exams and patient outcomes, specifically the likelihood of patient mortality and readmission to the hospital. Unlike periodic assessments during residency, which did not show a connection to patient outcomes, the study found that higher board exam scores were associated with lower risks of patients dying within seven days of admission or being readmitted afterward. Conducted by researchers from Harvard Medical School and the American Board of Internal Medicine (ABIM), the
