The walls were closing in on Bruce and Maggie Tate. Isolation forced on them by the pandemic, combined with America's growing political factionalism, threatened their bonds with community and family. Something had to change. Maggie's surprising answer: buy a boat, learn to pilot it, and embark on the Great Loop. For nine months Bruce and Maggie navigated rivers, coastal waters, lakes, locks, and loss. Against all odds, they conquered the Loop, and along the way found common cause across po...

When you're done, you'll have a working binary clock and a good appreciation of the work that goes into a hardware syste...

Elixir is a functional language that crosses many boundaries. With a syntax borrowing heavily from Ruby, a runtime that is on the Erlang BEAM, a macro system like that in Lisp, and a streaming library like you might find in Haskell, Elixir takes the best features from many environments. Elixir borrows from Erlang's "Let It Crash" philosophy, and adds significant improvements with structs, first-class hygienic macros, and abstractions such as protocols. Many of these ideas were borrowed fro...

The Elixir programming language has become a go-to tool for creating reliable, fault-tolerant, and robust server-side applications.

Sometimes the simplest answer is the best. Many Enterprise Java developers, accustomed to dealing with Java's spiraling complexity, have fallen into the habit of choosing overly complicated solutions to problems when simpler options are available. Building server applications with "heavyweight" Java-based architectures, such as WebLogic, JBoss, and WebSphere, can be costly and cumbersome. When you've reached the point where you spend more time writing code to support your chosen framework ...
