More fun with fast remainders when the divisor is a constant
20 February 2019 | 1:00 am

In software, compilers can often optimize away integer divisions, and replace them with cheaper instructions, especially when the divisor is a constant. I recently wrote about some work on faster remainders when the divisor is a constant. I reported that it can be fruitful to compute the remainder directly, instead of first computing the quotient … Continue reading More fun with fast remainders when the divisor is a constant

Science and Technology links (February 16th, 2019)

In their new book Empty Planet, Bricker and Ibbitson argue that within the next 30 years, Earth’s population will start to rapidly decline. They believe that official population predictions overestimate future populations because they fail to fully take into account accelerating cultural changes. It is believed that senescent cells are a major driver of age-related … Continue reading Science and Technology links (February 16th, 2019)

My iPad Pro experiment: almost two years later
14 February 2019 | 2:34 pm

Soon after the first iPad Pro came out, I bought one and started using it daily. The experiment is ongoing and I thought it was time to reflect upon it further. Before I begin, I need to clarify my goals. When I started this experiment, some people objected that I could get a hybrid (laptop/tablet). … Continue reading My iPad Pro experiment: almost two years later
