Nushell Niceties: Bumping Semantic Version
A blog by @mrhaki

In a previous blogpost you can learn about the semver command in Nushell to transform a string value into a semver type. With the semver bump command you can increase one of the components of the semver type. For example to increase the major version part you can use semver bump major. This command will also update the minor and patch parts if needed. The result is a...

PKI in a Nutshell
A blog by Ronald

This blog briefly describes theoretically how Public Key Infrastructure (PKI) works. It also introduces the key concepts used in PKI. This is done by describing encryption, decryption, hashing, signing, and authentication using mathematical notations.

Battle-testing Temporal - Part 1
A blog by Robbert

Temporal is gaining traction spearheading a new generation of Workflow tools/frameworks. Namely Durable Execution frameworks. Unlike most Workflow tools/frameworks, Durable Execution frameworks take a code-centric approach (no external models) meant to assist the developer in building complex Workflows (Sagas) that can take anywhere from...

Nushell Niceties: Checking If Value Is In List Or String Or Key In Record
A blog by @mrhaki

Nushell has the in operator to check if a value is an element of list. With the same in operator you can check if a string is a substring of another string. And finally you can use the in operator to check if a key is in a record. When you use the operator the value you want to check is defined before the operator and the list, other string...

Flyway the Right Way
A blog by Ronald

Sometimes when you upgrade your application the new version does not work correctly, and you need to downgrade. When you are unlucky you did some changes in your database that cannot be undone. In that case you need to restore the database from a backup, which is usually quite cumbersome and time-consuming. How nice would it be if you could just...
