New Julia Tool for Genomic Data Visualization Published in Nature: Nature published an article titled VIVA (VIsualization of VAriants): A VCF File Visualization Tool about a new Julia tool for visualizing genomic data:

"VIVA employs the Julia programming language, a high-level, high-performance, dynamic programming language for numerical computing. VIVA is among the first user-level tools of its kind written in the Julia programming language. Additionally, it can be integrated into workflows with other tools hosted by BioJulia, the Julia language community for biologists and bioinformaticians."

Julia Computing Researches TIOBE Language Ranking: Julia Computing published a blog post titled "Thoughts on TIOBE's Language Ranking Methodology", in which we also discuss alternative metrics from PYPL, GitHub, RedMonk and IEEE Spectrum. As of Sept 2019, Julia is ranked #8 in GitHub stars and forks (among languages developed on GitHub), #22 on PYPL, #23 on IEEE Spectrum, #33 on RedMonk and #36 according to the TIOBE index.

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 more than 10 million times 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. 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.
