Effective Remote Work
The office isn't as essential as it used to be. Flexible working hours and distributed teams are replacing decades of on-site, open-plan office culture. Wherever you work from nowadays, your colleagues are likely to be somewhere else. No more whiteboards. No more water coolers. And certainly no Ping-Pong. So how can you organize yourself, ship software, communicate, and be impactful as part of a globally distributed workforce? We'll show you how. It's time to adopt a brand new mindset. Remote working is here to stay. Come and join us. Remote working is on the rise. Whether or not we are remote workers, it is likely we are all part of a global workforce. We need to learn to interact remotely, because we are all remote from someone in some way. Rather than simply simulating the way we'd usually work together via digital means, we have to learn new communication skills and adopt a different mindset in order to work remotely effectively, efficiently, and, most importantly, healthily. ...

Build a Weather Station with Elixir and Nerves
The Elixir programming language has become a go-to tool for creating reliable, fault-tolerant, and robust server-side applications. Thanks to Nerves, those same exact benefits can be realized in embedded applications. This book will teach you how to structure, build, and deploy production grade Nerves applications to network-enabled devices. The weather station sensor hub project that you will be embarking upon will show you how to create a full stack IoT solution in record time. You will build everything from the embedded Nerves device to the Phoenix backend and even the Grafana time-series data visualizations. Elixir as a programming language has found its way into many different software domains, largely in part to the rock-solid foundation of the Erlang virtual machine. Thanks to the Nerves framework, Elixir has also found success in the world of embedded systems and IoT. Having access to all of the Elixir and OTP constructs such as concurrency, supervision, and immutability mak ...

Taking Kubernetes from Test to Production
With Kubernetes came many new concepts, particularly around networking and traffic management. Alongside these new concepts were entirely new classes of tools, designed for ephemeral, containerized, and distributed application deployments. In particular, Ingress controllers and service meshes did not exist prior to the Kubernetes era. Nor were Layer 4 and Layer 7 protocols and traffic typically managed from the same control plane. At a granular level, Kubernetes introduces new complexities around security and management. Simple tasks like load balancing are very different in a realm where infrastructure is 100% ephemeral and often moving constantly - both in terms of setting up new instances with fresh IP addresses and geographically moving around the globe. These new traffic management concepts and tools have the power to vastly improve developer experience and accelerate app development and delivery cycles through greater resilience, higher performance, and better security. But wh ...
