Database representation of graph-structured information is fascinating in its own right.

I have been studying genomics technology in which graphs play a big role, both as information-structure that is the basis of certain algorithms, as well as the data driving visualizations or visually-interesting real-world structures.

As an example, here is a visualization of a protein complex that catches the eye.

See http://en.wikipedia.org/wiki/FOXP2#/media/File:Protein_FOXP2_PDB_2a...

The image is a Richardson diagram which is (mostly) automatically generated from a database describing the molecular structure of the protein. This type of diagram was invented (i.e. originally hand-drawn) by Jane Richardson, PhD.

I wonder if the book "Graph Databases" touches on this.

Presently, I am doing a research study on a particular feature of the epigenome. It involves large DNA databases (actually, structured flat files), elaborate algorithms for sequence correlation, and histone complexes. Each of these involves graph-theoretic representations and inference functions from graph structures.

The "databases" I know for DNA, the transcriptome, pathways, etc. do not lend themselves to conventional SQL, or even noSQL as far as I know to date. (Chime in anyone? )

I will be presenting a paper at the IEEE SouthCon conference in April 2015 which touches on a graph-theoretic feature of certain (sequencing) problems lending itself to massively-parallel-ization of linearly-expressable algorithms.

I am pleased to see a free book on graph databases. Thanks!

KubeCon EU: Backstage, Crossplane and Others Preparing for CNCF Graduation

More projects from the CNCF incubated level are preparing to graduate for an ever-widening cloud native ecosystem. The Backstage community has worked on a more robust architecture, and Crossplane aimed to improve its developer DX. KubeFlow and Volcano, both tools promising to improve AI adoption within the Kubernetes ecosystem, are working on easier installation and more features, respectively.

How to Tame Technical Debt in Software Development

According to Marijn Huizenveld, discipline is key to preventing accumulating technical debt. In order to be disciplined you should make it difficult to ignore the debt. Heuristics like fixing small issues immediately, agreeing on a timebox for improvement, and making messy things look messy, can help tame technical debt.

Redis Switches to SSPLv1: Restrictive License Sparks Fork by Former Maintainers

Redis has recently announced a change in their license by transitioning from the open-source BSD to the more restrictive Server Side Public License (SSPLv1). The move has promptly led to a fork initiated by former maintainers and reignited discussions surrounding the sustainability of open-source initiatives.
