We often associate loneliness with seniority, an image of elderly people cooped up inside. However, young adults are twice as likely to be lonely than seniors—a whopping 79 percent of 18- to 24-year-olds report feelings of loneliness.

But until Substack makes it clear that it will take proactive steps to remove hate speech and extremism, the current size of the problem isn’t relevant. The company’s edgelord branding ensures that the fringes will continue to arrive and set up shop, and its infrastructure creates the possibility that those publications will grow quickly. That’s...

Both describe Stack Overflow as the solution to a very specific problem: programming knowledge locked up in minds and forums whence it's difficult to retrieve. They also explain how they intend to solve the problem including... See more

One of the best ways to build the confidence to get started and enter the exploratory process of finding a solution is to set as well-defined a search space as you can: outline the "hard edges". Setting this defined space gives you constraints to comfortably work within, almost like a cozy room with padded walls where we've got the freedom to... See more

A major limitation exists for spaced repetition software (e.g. Anki, SuperMemo, or other flashcard-style systems), in my experience using them for several years for long-term memory: it's neither necessary nor sufficient to use this software to learn certain topics.

Several excellent physics and math students I worked with have never used spaced... See more
