Distributed stream processing systems are used to read large volumes of data and perform operations across those data streams.  These stream processing systems often build off of the MapReduce algorithm for collecting and aggregating large volumes of data, but instead of processing a calculation over a single large batch of data, they process data on

Large companies generate large volumes of data. This data gets dumped into a data lake for long-term storage, then pulled into memory for processing and analysis. Once it is in memory, it is often read into a dashboard, which presents a human with a visualization of the data.  The end-user who is consuming this data

Data infrastructure has been transformed over the last fifteen years.  The open source Hadoop project led to the creation of multiple companies based around commercializing the MapReduce algorithm and Hadoop distributed file system. Cheap cloud storage popularized the usage of data lakes. Cheap cloud servers led to wide experimentation for data tools. Apache Spark emerged

A data platform contains all of the data that a company has accumulated over the years. Across a data platform, there is a multitude of data sources: databases, a data lake, data warehouses, a distributed queue like Kafka, and external data sources like Salesforce and Zendesk. A user of the data platform often has a

Nubank is a popular bank that is based in Brazil. Nubank has more than 20 million customers, and has accumulated a high volume of data over the six years since it was started. Mobile computing and cloud computing have given rise to “challenger banks” that operate more like software companies. When a software company reaches

The Changelog is a podcast about the world of open source. As open source has become closely tied with the entire software development lifecycle, The Changelog has expanded its coverage to the broader software industry. Since starting the podcast ten years ago, Adam Stacoviak and Jerod Santo have become full-time podcasters, and they have started

Animations can be used to create games, app tutorials, and user interface components. Animations can be seen in messaging apps, where animated reactions can convey rich feelings over a text interface. Loading screens can become less boring through animation, and voice assistant products can feel more alive through animation. But we still don’t see much

Robotics has changed modern agriculture. Autonomous systems are powering the tractors, cotton pickers, and corn cutters that yield plants at industrial scale. John Deere is a company that has been making farm equipment for 183 years. Over that period, the planting and harvesting process has become increasingly mechanized, and John Deere has been at the

Venture capital investing requires an understanding of market dynamics, technology, and finance.  There is also an element of human nature. Consumer trends can make or break the viability of a new product. And early stage venture investing is always a bet on a small team or individual founder. Early stage investments are usually into companies

Stock trading takes place across a variety of software platforms. Etrade and Schwab have allowed individual traders to buy securities for decades. Robinhood built a business around a similar model, but also removed the commission. Wealthfront and Betterment provide “roboadvisor” services that abstract away the underlying securities and focus on managing a risk profile. Each
