Flexible Non-intrusive Dynamic Instrumentation for WebAssembly
A key strength of managed runtimes over hardware is the ability to gain detailed insight into the dynamic execution of programs with instrumentation. Analyses such as code coverage, execution frequency, tracing, and debugging, are all made easier in a virtual setting. As a portable, low-level bytecode, WebAssembly offers inexpensive in-process sandboxing with high performance. Yet to date, Wasm engines have not offered much insight into executing programs, supporting at best bytecode-level step…

Dear Mihaela,
Stating, as you have just done, that all Jews are pro-genocide and pro-apartheid and thereby that anyone who opposes genocide and apartheid is a “Jew-hater” is both factually wrong and terribly antisemitic. https://mastodon.social/@mihaelamj/112049454953033203<…

Micah Parsons sends Cowboys hater Stephen A. Smith to hospital after basketball mishap
From @ToddBrock24f7: A practice session for the NBA All-Star Celebrity Game ended with the noted Cowboys hater going to the hospital for ankle X-rays.

Updated my feed retriever to be a better web citizen (e.g. respecting caching headers, using https://github.com/npm/make-fetch-happen) only to learn that at least one news website doesn't respond—at all—when I use its default `User-Agent` header. So to make it work there I'm…

Thank you, @…, Heather Cox Richardson's analyses are spot on every day. Sununu admitting, on video, he (and all who will follow the OrangeFace) are greedy, immoral scunge is just the beginning of this dissection. After reading her, you feel good anyway. You feel determined.

Primordial Black Hole Neutrinogenesis of Sterile Neutrino Dark Matter
Sterile neutrinos are well-motivated and actively searched for new particles that would mix with the active neutrinos. We study their phenomenology when they are produced in the evaporation of early Universe black holes, a novel production mechanism that differs from all others and does not depend on the active-sterile mixing. The resulting hotter sterile neutrinos have a distinct spectrum and could be warm dark matter in the 0.3 MeV to 0.3 TeV mass range, distinct from the typical keV range. T…
