Software Weekly - 09/23/2019

Kafka applications, geo-distributed SQL, minimalistic code, faster binary search, software architecture overrated, AI stop bullying & more


Last week’s most popular episode:  Kafka Applications with Tim Berglund. Tim discusses how applications are built today using Kafka–including systems that are undergoing a refactoring, data engineering applications, and systems with a large number of communicating services.

Old favorite: Kafka Design Patterns with Gwen Shapira. Gwen discusses practical use cases and design patterns of Kafka, including log management, data enrichment, large scale analytics, and reconciling data between different servers.

 Building Intelligent Apps with MongoDB and Google Cloud: In this free webinar, you’ll learn how to build intelligent apps on MongoDB with Google Cloud ML Engine and DialogFlow. We'll discuss a specific e-commerce example with real-time product recommendations and a conversational chatbot interface. Check it out here.

Interesting Picks in Software Engineering and Architecture

CockroachDB: Architecture of a Geo-Distributed SQL Database. The best thing you will read/watch on distributed systems this week. Learn about distributed New SQL Database. CockroachDB is based on similar technology as Google Spanner.

Enhancing Bandaid load balancing at Dropbox by leveraging real-time backend server load information. Dropbox explored leveraging real-time load information from backend servers to make better load balancing decisions. A great read on current challenges of scaling L7 load balancers especially in a microservices-oriented architecture.

Learning the hard way: Microservices. Mistakes were made and learned from. "You're not Google!"

Learning Machine Learning - a comic. Learn about ML and the journey we call gradient descent - a comic by Google.

6 ways minimalism can help you write clean code, Favorite advice: Don’t write code “just in case” and Avoid "shiny object" syndrome.

Contemporary Front-end Architectures. An exhaustive list of front-end framework architectures from MVC to MVP all the way to Svelte and compiler-based frameworks.

Speeding up independent binary searches by interleaving them. A fascinating read into how running multiple binary searches is impacted by computer architecture (specifically how speculative execution works). "I can prevent the processor from usefully executing more than one search either by inserting memory fences between each search or by making the target of one search dependent on the index found in the previous search."

Software Architecture is Overrated, Clear and Simple Design is Underrated. Best advice: write it up via simple documentation with simple diagrams and talk about tradeoffs and alternatives. I like this because the developers are designing and iterating on their systems from the bottom up versus having an architect dictate top-down how things should be.

Going fast slowly. Varnish cache hits 10 years. Reflections on lines of code written. "I no longer think about code lines as an asset to be accumulated, but rather as an expenditure to be avoided."

Is serverless the end of ops? Analyzing the pros and cons of serverless architectures. I find it funny that after the discussion of serverless, GitLab jumps to talking about Knative and Kubernetes versus Lambda, Functions, etc. K8s => more ops.
GitLab Commit is the official conference for GitLab, and it is coming to London October 9 at The Brewery. Sign up with code COMMITSED to save 30% on conference passes at There are some great speakers from VMWare, Porsche, and Gitlab itself.

What's New in Tech

Artificial intelligence being used in schools to detect self-harm and bullying. Humanity will finally be reduced to a bunch of numbers and formulas. "There is the scope for mission creep, where somebody in a school says this would be a great tool to sort children into different classrooms or decide which students should go on to university and which shouldn't." 

Harry can't have his surname on his school books - because of GDPR. Instead, they have to call him Harry 2. “The school has taken this decision to ensure compliance with GDPR and reduce the risks of a breach occurring going forward.

New Query Language for Graph Databases to Become International Standard. New ISO Database Language Since SQL. Will it be used by other databases besides Neo4j though?
