Violating memory safety with Haskell's value restriction A common issue in impure ML-style languages with polymorphism and mutable references is the possibility of polymorphic references. In a hypothetical impure language that had both these features, but no mitigations against polymorphic references, the following code would be extremely unsafe. unsafeCoerce :: a -> b = unsafeCoerce x let dangerous = ref Nothing dangerousref := Just x dangerous case dangerous of dangerous Nothing -> error "u

I spent some time reading about “Durable Execution Engines” (eg: Temporal) and explored possible connections to earlier concepts like database transactions, distributed transactions, and building RPC/Microservice based systems in a fault tolerant manner. In this post I’ll try to summarize some of my learnings. How useful it is will depend on how much of this you already know! Among other things, I relied on these great overviews: The Modern Transactional Stack (by some a16z folks) and What is Du

It's a fact of life that as we age, our bodies will change. And that includes our teeth and mouths. "Teeth take quite a journey as time goes by," says cosmetic dentist Dr. David Wagner, DDS. "As we age, our mouths go through some interesting shifts. Gums may start to pull back, making teeth appear longer and exposing their roots. Saliva production tends to slow down, which can lead to dryness and a higher chance of cavities." Your medications may even affect your oral health. These are the age-

Martin Luther King Jr. said that “the arc of the moral universe is long, but it bends toward justice.” Was he right? Some skeptics might question whether there even is such a thing as “the moral universe.” What we call morality, they may say, is nothing more than the subjective judgments of people in various times and places. Customs or religious teachings may impose a high degree of uniformity within a particular society, but cultures differ, and there is no basis for saying that one has gotten

Utah becomes first US state to ban fluoride in its water Utah's move to remove the mineral has been criticised by experts, who worry it will have consequences for oral health, especially for children. Fluoride has been added to US drinking water since 1945 to prevent cavities. Governor Spencer Cox signed the ban into law this week, which will go into effect on 7 May. Other states, including Florida and Ohio, are weighing similar legislation. Utah has become the first US state to ban the use

The Webb Space Telescope has given us our first glimpse of Neptune glowing with bright auroras, a visually stunning phenomenon that has long evaded scientists studying the ice giant. Using Webb’s near-infrared spectrograph, astronomers have captured new images of Neptune that finally reveal the planet’s mysterious auroral activity. Faint hints of Neptune’s auroras were first detected during Voyager 2’s flyby of the planet, but Webb’s latest discovery is the first direct evidence of the phenomen

The best treatment for a hard knock on the head might someday involve a quick sniff of a nasal spray.

Scientists at Mass General Brigham conducted the study, published Thursday in Nature Neuroscience. In brain-injured mice, the experimental spray appeared to improve the brain’s natural acute healing process wh
