Source: High-performance tidy trees visualization

Summary
This article introduces an algorithm to draw non-layered trees in linear time and relayout partially when some nodes change in O(d) time, where d is the maximum depth of the changed node. Engineers can use it to build fast tree editor tools like mind maps.

Fact

🌳 The algorithm introduced in this article allows for the fast layout of trees with tens of thousands of nodes within a web browser in just a few milliseconds.

🌿 A tidy drawing of a tree should obey aesthetic rules, including no overlapped node, no crossed line, and small subtrees at the far left or far right should be adjacent to larger subtrees.

🌱 In tree visualization, each node may have a variant width and height. The tree can be drawn as layered, where nodes with the same depth are horizontally aligned, or non-layered, where there is a fixed vertical distance between parent and children.

Source: Bruno Schulz: An Artist, A Murder, and the Hijacking of History review – an extraordinary mind and a cruel death

Summary
Bruno Schulz, a Jewish writer and artist, whose works are difficult to describe, has attracted a smaller but more devoted group of readers, especially among novelists who follow in his wake. His stories are set in a phantasmagoric version of the city of Drohobycz, where Schulz was born and died, and largely in and around the cloth shop on the market square that his parents owned, but in a version of these places where time and space have become molten and malleable.

Fact

📚 Schulz is a quintessential writer’s writer, propping up and popping up within the fictions of Philip Roth, Cynthia Ozick, Nicole Krauss, Danilo Kiš, David Grossman, Olga Tokarczuk, and many others.

🎨 Schulz stayed alive for as long as he did during the Holocaust by producing paintings for public consumption.

🧑‍🦳 His stories are reminiscent of Maurice Sendak’s with their bewitching childhood worlds filled with galumphing, unpredictable adults.

Source: Stop Saying C/C++

Summary
Saying “C/C++” masks the significant differences between the two languages. The languages have different standard libraries, implementations and standards. C++ is noticeably different from C, and the languages have drifted apart over time.

Fact

🤝 C and C++ are unique programming languages, although C++ was based on C, these two languages have drifted apart over the years.

🧱 C++ is not just C with classes; it has different standard libraries, implementations, and standards than C.

🔌 Some of the differences between C and C++ include incompatibility with void pointers and K&R syntax, making it almost impossible to use K&R syntax with C++ unless it is formatted according to ASCI C.

🌠 Using the “C/C++” term masks the differences between the languages and may lead to confusion from beginner programmers who might think they are the same language, making it harder to learn them.
