Newsletter May 2021 - DataFrames 1.0 Released

The much anticipated release of DataFrames.jl version 1.0 provides Julia users with a fully integrated, new and improved solution for data analysis in Julia. Release notes are available here. In addition to providing a stable API going forward, there are significant performance improvements in this release that include multi-threading and faster joins. More information about DataFrames.jl is available in the DataFrames documentation.

“DataFrames.jl provides a set of tools for working with tabular data in Julia. Its design and functionality are similar to those of pandas (in Python) and data.frame, data.table and dplyr (in R), making it a great general purpose data science tool, especially for those coming to Julia from R or Python. DataFrames.jl plays a central role in the Julia Data ecosystem, and has tight integrations with a range of different libraries.”

JuliaSim: JuliaSim is a next generation cloud-based modeling and simulation platform, combining the latest techniques from scientific machine learning with equation-based digital twin modeling and simulation. Dr. Chris Rackauckas presented Accelerating Simulation of Stiff Nonlinear Systems Using Continuous-Time Echo State Networks with JuliaSim. Click here for more information.

Julia for Data Science: Dr. Josh Day (Julia Computing) has launched Julia for Data Science, a portal for data scientists who want to learn and use Julia.

About Julia and Julia Computing

Julia is the fastest high performance open source computing language for data, analytics, algorithmic trading, machine learning, artificial intelligence, and other scientific and numeric computing applications. Julia solves the two language problem by combining the ease of use of Python and R with the speed of C++. Julia provides parallel computing capabilities out of the box and unlimited scalability with minimal effort. Julia has been downloaded by users at more than 10,000 companies and is used at more than 1,500 universities. Julia co-creators are the winners of the 2019 James H. Wilkinson Prize for Numerical Software and the 2019 Sidney Fernbach Award. Julia has run at petascale on 650,000 cores with 1.3 million threads to analyze over 56 terabytes of data using Cori, one of the ten largest and most powerful supercomputers in the world.

Julia Computing was founded in 2015 by all the creators of Julia to develop products and provide professional services for businesses and researchers using Julia.
