How BuzzFeed Migrated from a Perl Monolith to Go and Python Microservices
Starting in 2016 BuzzFeed began a re-architecture project moving from a single monolithic application written in Perl to a set of microservices. The main reason for the move was that the Perl application was proving hard to scale, essential given that buzzfeed.com alone serves about 7 billion page views/month.

Can People Trust the Automated Decisions Made by Algorithms?
The use of automated decision making is increasing. These algorithms can produce results that are incomprehensible, or socially undesirable. How can we determine the safety of algorithms in devices if we cannot understand them? Public fears about the inability to foresee adverse consequences has impeded technologies such as nuclear energy and genetically modified crops.

Picking an Active-Active Geo Distribution Strategy: Comparing Merge Replication and CRDT
Modern distributed applications are fuelling the growing demand for distributed active-active, multi-master databases. While most popular databases support multi-master deployment, different databases employ different techniques. LWW, MVCC, merge replication and CRDTs deliver eventual consistency, offering read and write access with local latency and remaining available during network partitions.

Ballerina Tutorial: A Programming Language for Integration
Ballerina is a new programming language and platform whose objective is to make it easy to create resilient services that integrate and orchestrate across distributed endpoints. Ballerina’s design principles focus on baking integration concepts into a language, including a network-aware type system, sequence diagrammatic syntax, concurrency workers, being “DevOps ready”, and environment awareness.

Developers. Our Last, Best Hope for Ethics?
In March, Stack Overflow published their Developers’ Survey for 2018 and for the first time they asked questions about ethics. The good news is that to “Do Developers Have an Obligation to Consider the Ethical Implications of Their Code?” nearly 80% responded “yes”. However, only 20% felt ultimately responsible for their unethical code, and 40% would write unethical code if asked.
