Software Weekly - 08/05/2019

Data Mesh, Capital One AWS breach, design patterns for microservices, decision trees in graph database & more


Last week’s most popular episode: Data Mesh with Zhamak Deghani. Zhamak discusses how to move beyond a monolithic data lake to a distributed data mesh and other challenges in data infrastructure. 

Old favorite: Data Warehouse with Christian Kleinerman. Christian discusses the difference between a data warehouse, a data lake, and a transactional database, and the process of moving data sets between them, often known as ETL.

 Datadog's intuitive, full-stack monitoring platform provides unified insights into your metrics, traces, and logs. Check it out.

Interesting Picks in Software Engineering and Architecture

The Technical Side of the Capital One AWS Security Breach. Misconfigured firewall allowed the hacker access to a server where they were able to gain access to other AWS resources (S3 buckets, etc). A hacker gained access to 100 million Capital One credit card applications and accounts.

Treading in Haunted Graveyards. Interesting post about infrastructure/configuration as code and how it essentially changed data processing workloads, and opened doors for opportunities to reduce AWS bills.

Design Patterns for Microservices. Check out 21 patterns for building microservices and learn general architectural patterns and how to apply them.

Running Decision Trees in Neo4j. How decision trees are used to make near-real-time decisions using a graph database. The example is the nightclub entrance criteria. Fascinating read. 

Safely Rewriting Mixpanel’s Highest Throughput Service in Golang. As they moved from Python to Golang, a lot of work was put into Kubernetes infrastructure in order to allow shadow testing and migration. They used Diffy to verify that API responses were the same by comparing the old and new APIs. 

Mapper Contexts & Supercontexts: Decoupling Domain-Specific and Domain-Generic Bounded Contexts. A great guide on some DDD patterns and how to apply them for a simple push vs pull model. Great read.

Four Better Rules for Software Design. The post specifically dives into abstractions, duplication, and ambiguity.

The 3 Laws of Locality for UX design. These apply also to software design and how you build consumer products and developer tooling. 

10 docker-compose and Docker commands that are useful for active development. Even if you use Docker every day, you will probably learn something new. 

Announcing PartiQL: One query language for all your data. Amazon announces a SQL-compatible language that supports non-relational, schemaless, and other data formats.

G2i is a hiring platform run by engineers that matches you with React, React Native, GraphQL, and mobile engineers who you can trust. They know how product development works and can help find you the perfect engineer for your stack. Go to to learn more about G2i.

What's New in Tech

AP Sources: Boeing changing Max software to use 2 computers. Don't you need 3 for high availability? This is an interesting approach to solving the problem.

Domino’s takes its case for non-accessible design to the Supreme Court. Just because you couldn't, doesn't mean you should. What side of history do you want to be on? Maybe time for more online regulation for accessible design. 

No Jail Time for “WannaCry Hero”. A hero who was also involved in spreading malware gets sentenced to time served plus one year of supervised release.
