Uber Tech Stack
This post is based on research from many Uber engineering blogs and open-source projects. If you come across any inaccuracies, please feel free to inform us. The corresponding links are added in the comment section.
Web frontend: Uber builds Fusion.js as a modern React framework to create robust web applications. They also develop visualization.js for geospatial visualization scenarios.
Mobile side: Uber builds the RIB cross-platform with the VIPER architecture instead of MVC. This architecture can work with different languages: Swift for iOS, and Java for Android.
Service mesh: Uber built Uber Gateway as a dynamic configuration on top of NGINX. The service uses gRPC and QUIC for client-server communication, and Apache Thrift for API definition.
Service side: Uber built a unified configuration store named Flipr (later changed to UCDP), H3 as a location-index store library. They use Spring Boot for Java-based services, uAct for event-driven architecture, and Cadence for async workflow orchestration.
Database end: the OLTP mainly uses the strongly-consistent DocStore, which employs MySQL and PostgreSQL, along with the RocksDB database engine.
Big data: managed through the Hadoop family. Hudi and Parquet are used as file formats, and Alluxio serves as cache. Time-series data is stored in Pinot and AresDB.
Data processing: Hive, Spark, and the open-source data ingestion framework Marmaray. Messaging and streaming middleware include Apache Kafka and Apache Flink.
DevOps side: Uber utilizes a Monorepo, with a simplified development environment called devpod. Continuous delivery is managed through Netflix Spinnaker, metrics are emitted to uMetric, alarms on uMonitor, and a consistent observability database M3.

हनुमान के महान गुण क्या हैं?
उनमें दो महान गुण थे, पहला था अपार साहस: "जब तक मैं अपने भगवान के साथ हूं, कुछ भी गलत नहीं हो सकता। दूसरा था "विनम्रता", वे दो विपरीत विशेषताओं से समृद्ध थे।

Today is Hanuman Jayanthi. He is the primary disciple of Lord Ram, the Avatar Purush from the ancient Indian scripture of Ramayan. The meaning of the name Hanu-maan means one has killed his pride or prestige. Even the condition of 'aham brahmasmi' (I am god) is possible only if we give up this idea of 'maan' or prestige
On this Hanuman Jayanthi, let us remember these great qualities of Hanuman like courage , humility, and immense devotion. Let's try to emulate them.

College completely failed to teach me data analysis.
So I spent over 10,000 hours learning Python.
Then, I picked the 13 best libraries for machine learning and data analysis.
But unlike college, these won't cost you $120,000.
