How Uber Engineering Evaluated JSON Encoding and Compression Algorithms to Put the Squeeze on Trip Data
For compression, we put three lossless and widely accepted libraries to the test: Snappy zlib Bzip2 (BZ2) Snappy aims to provide high speeds and reasonable compression. BZ2 trades speed for better compression, and zlib falls somewhere between them. Testing Our goal was to find the combination of encoding protocol and compression algorithm with the most compact result at the highest speed. We teste
JSON API — A specification for building APIs in JSON
If you’ve ever argued with your team about the way your JSON responses should be formatted, JSON:API can help you stop the bikeshedding and focus on what matters: your application. By following shared conventions, you can increase productivity, take advantage of generalized tooling and best practices. Clients built around JSON:API are able to take advantage of its features around efficiently cachi

7 Command-Line Tools for Data Science | Jeroen Janssens
Data science is OSEMN (pronounced as awesome). That is, it involves Obtaining, Scrubbing, Exploring, Modelling, and iNterpreting data. As a data scientist, I spend quite a bit of time on the command-line, especially when there’s data to be obtained, scrubbed, or explored. And I’m not alone in this. Recently, Greg Reda discussed how the classics (e.g., head, cut, grep, sed, and awk) can be used for
