Steganography. The art of hiding something right under your nose. For as long as humans have been alive, we’ve been trying to hide things — whether it’s our last slice of pizza or the location of a buried treasure. Do you remember the cool invisible lemon ink trick, where we’d write the secret message with lemon and heat the paper…
LibreSSL is a fork of OpenSSL that improves code quality and security. It was originally developed for OpenBSD, but has since been ported to several platforms (Linux, *BSD, HP-UX, Solaris, macOS, AIX, Windows) and is now the default TLS provider for some of them. When debugging a program that uses LibreSSL, it can be useful to see decrypted network traffic.…

In my book I discuss the importance of context in reading and writing mathematics. An early step in becoming comfortable with math is deciphering the syntax of mathematical expressions. Another is in connecting the symbols to their semantic meanings. Embedded in these is the subproblem of knowing what to call the commonly used symbols. The more abstract you go, the…

Banks confront new customer demands, and the question: When to create or collaborate?
Thoughtworks InsightsAs the needs and expectations of Australians rapidly evolve, the country’s traditional banking institutions are under renewed pressure to diversify the end-user experience. The digital economy has fundamentally changed the ways in which people engage with businesses, and significantly enhanced their comfort with using technology to gain instant access to goods and services.
While a lot has changed in Australian banking in recent years, loan pricing strategies have remained remarkably consistent - in general, not to the benefit of banks, or their customers. But a perfect storm of technology, demand and industry trends is poised to challenge long-established practices, and the early responders are likely to secure the advantage.
