Newsletter January 2021

Julia adoption accelerated at a rapid pace in 2020.

Julia Rises from #47 to #23 in TIOBE Index: According to TIOBE CEO Paul Jansen, “The top candidate [to break into the top 20 in 2021] is without doubt Julia, which jumped from position 47 to position 23 in the last 12 months.” Among languages developed on GitHub, Julia ranks #7 in stars and #9 in forks. Julia also ranks #24 in the PYPL Index and #19 in the IEEE Spectrum ranking.

• DevClass: “Those more interested in hot languages of the future should keep an eye on dynamic programming language Julia, which is currently gaining followers amongst researchers doing scientific or numerical computing. According to Jansen, a jump from position 47 to 23 in the last 12 months makes it top candidate for an entry into the top 20 of the list and maybe even staying there.”

• ZDNet: “TIOBE also predicts that Julia, a programming language with roots in MIT, will become a top 20 language in 2021. Julia has only been available since 2012 but made it to TIOBE's top 50 in August 2018. Julia was created for tasks in scientific computing, machine learning, data mining, large-scale linear algebra, distributed, and parallel computing. It aims for the speed of C but to be as useful for general programming as Python.”

• SD Times: “TIOBE predicts Julia, Dart and Rust will reach the top 20 this year.”

• TechRepublic: "’Are there any new top 20 entries to be expected in 2021? Top candidate is without doubt Julia, which jumped from position 47 to position 23 in the last 12 months. Dart and Rust are other candidates, but both of them touched the top 20 already without being able to stay for a longer time,’ said Jansen in a blog post.”

Julia for Modeling Turbulence: Jean-Christophe B. Loiseau shared images and code from his model of decaying turbulence: “Computation of the Navier-Stokes equations takes less than 50 lines of code, including blank lines and my (numerous) comments and is still super readable. I'll definitely use it from my numerical methods class! Given how fast it runs on my 6 years-old laptop and how easily it can be integrated with tools such as Flux.jl, I may also use it to explore crazy ideas combining nonlinear simulations, optimization and machine learning to identify coherent structures in 2D turbulence :)” Nima Dehghani adds: “This is a testament to the elegance of Julia. I also just finished a series of [an] insane number of calculations (millions of diffusion on networks+MC sampling) [that] took 2 weeks with Julia (64 core machine w RTX GPU). On python, a fraction of it took 1 month. Thanks @JuliaLanguage

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 to businesses and researchers using Julia.
