why & how to create isolated environments per pull request

Avner Sorek from env0 gives a mini-tutorial on how & why to create an isolated test environment for your pull requests and integrate the process with git-ops (git actions in your continuous integration pipeline). The power of containerization enables creating temporary environments that are completely isolated in all phases of developing your web application from machine-local through all phases of testing, integration, and deployment.  And if you are in a hurry, you can run many of them in parallel.  On a public cloud the instant provisioning and tear-down of these environments and all infrastructure needed are simple and straightforward.  Some private, on-premise clouds are not yet capable of enabling these features.

Tau Zero by Poul Anderson

Despite the 1967 outdated cosmology and physics, this book still holds up well.  I am very sorry I did not read it during my personal "golden age" of science fiction (15 years old) but I still loved this book.  I picked the book up during my personal celebration of the 60-year-old concept of a Bussard Ramjet that uses interstellar Hydrogen for fuel.  The ship in this story (called the Leonora Christine) is one of the main characters.  5/5 Stars.

The Evolutionary Void by Peter F Hamilton

Thrilling conclusion with great plot twists; some lazy writing with late introduction of new powerful minor characters. 4/5 Stars.

Another perspective on Chaos Engineering as Validation Testing

The folks over at ChaosMesh.com have a kindler, gentler view of Chaos Engineering as another approach to testing.

HashiConf (Digital) review

Rich Burroughs gives us a long, detailed review of the virtual HashiConf[erence].  The keynotes are interesting and the new features in Terraform 0.13 are cool.

The Dreaming Void by Peter F. Hamilton

Fun, great story, rich characters.  Awesome dialogue, fun space opera, 4/5 Stars.

The Temporal Void by Peter F Hamilton

Fantastic story.  5/5 Stars.

Embers of War by Gareth L Powell

Not bad; good awe-and-wonder.  Characters aren't great.  3/5 Stars.  I may read the next few.

Gods and Legionnaires, Galaxy's Edge Savage Wars, book 2

OK, not great.  Luckily no telekinesis or other magic stuff, but the living-in-a-simulation stuff is weak.  3/5 Stars. 

Higher, faster, further

(Nasa's X43-A Mach-10 X plane holds the jet aircraft speed record)

You may share the "dream of flying" higher, faster, & further that pilots, aviation, and space enthusiasts all have.  I grew up during the era of the "cold war" and the "space race" (to the moon).  During my formative years, the USA built and flew interstellar spacecraft, all components of autonomous apocalyptic doomsday devices, and  the iconic, ramjet-powered, blackbird; we brought people to the moon and back, and even tested and proved mach-3 compression lift that has not yet been replicated with modern X planes.  Mitch still loves watching ravens, raptors, and swallows enjoying the thrill of flight.  In his lucid dreams, Mitch flies. Recently, Mountain Aerospace Research tested their "Fenris" motor that is trying to combine an air breathing scramjet (such as the one designed in 1958 and flown in the X-43A pictured above), with a regular space rocket that uses stored oxidizer. The concept is a rebirth of the 45-year-old "Space Plane" project that was defunded. I hope their vehicle works!
