Distributed Ledger Technology, Blockchain, and IoT (Part 2)

May 03, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

Author’s note: If you do a bit of internet searching you will see both permissioned and permissionless distributed ledgers referred to as blockchains.  Some will disagree and call this a travesty, others will not.  The author claims to have no idea which side is right.  For the purpose of this and related blog posts blockchains may be used to referred to as either permissioned or permissionless.

In our previous post the definition of Distributed Ledger Technology (DLT) was introduced.  In this post we will go further in understanding the various types of DLT systems that can exist.  Recall from our previous post three key factors in defining the taxonomy of DLT; how to distribute the ledger, if the ledger is public or private, and who is responsible for maintaining the integrity of the ledger (permissioned/permissionless).  The figure below provides a graphical reference for keeping those three characteristics in mind.

Groundhog Day

Recently, a friend and I were sharing our love for the movie Groundhog Day. In this movie Phil, a disgruntled, cynical weather reporter (played by Bill Murray) visits a town to report on the emergence of the groundhog and whether this indicated 6 more weeks of winter. Of course, Phil has a terrible day and everything lives up to his cynicism. When he awakens the next morning… it is Groundhog Day all over again. Phil gets to live the same day over and over again… until the experience forces him to grow into a better version of himself.

 

This reminiscing got me to thinking… what lessons are suggested by Groundhog Day that help us in our roles on software development teams…?

The State of Windows DevOps

Apr 12, 2018 | by Samuel Thurston, Software Engineer | Tags: Cloud

DevOps as a practice has largely grown from the need to manage infrastructure and configuration for large scale applications. Frequently this has led to the technical choice of fleets of Linux-based application servers operating in a dynamic environment such as VMWare or AWS. The reasons for this technical choice are straightforward. Linux enjoys a lightweight and standardized remote administration mechanism through Bash and SSH. Software installation and dependency management are usually a breeze thanks to Linux distributions’ package managers.
