Pluto Notebooks Competition - Cash Prizes: JuliaHub is hosting a competition to highlight the best examples of Pluto notebooks being used in industry. Click here for more information and to submit. The submission deadline is August 1. Notebooks will be judged based on 3 criteria:

1. Subject Matter: Does it solve an interesting problem?
2. Presentation: How interactive is it and what kind of output visualization does it include?
3. Package Usage: How well does it use Julia package(s) / JuliaHub?

Notebooks that discuss an interesting problem and how it was solved are preferred, as opposed to purely instructional notebooks.

The prizes are:

• 1st Prize winner gets: $500 Cash + $500 Hours worth of free compute on JuliaHub
• 2nd Prize winner gets: $300 Cash + $300 Hours worth of free compute on JuliaHub
• 3rd Prize winner gets: $150 Cash + $150 Hours worth of free compute on JuliaHub

Free Compute on JuliaHub (20 hours): In addition to the features JuliaHub has always offered for free—Julia ecosystem search, package registration tools, a dedicated package server—the platform now also gives every user 20 hours of free compute. This allows people to seamlessly share Pluto notebooks and IDE projects with others and let them get their feet wet with computing without having to open up their wallets. Click here to get started or check out Deep Datta’s introductory video, “JuliaHub Is a Free Platform to Start Your Technical Computing Journey”, where he explains how and why to start using JuliaHub for cloud computing.

Free Webinar from JuliaHub: Breaking Boundaries in Data Science: Introducing Next-Generation Analysis and Visualization is a free one-hour Webinar hosted by JuliaHub’s Deep Datta and Phil Vernes. This Webinar takes place Wednesday, July 12 at 1 pm Eastern (US). Click here to register. Participants will explore the capabilities of Pluto notebooks and Plotly to visualize and uncover valuable insights, and learn how to build interactive and user-friendly Web applications to turn data into visualizations, including:

• How to import CSV data into a Julia Dataframe in JuliaHub
• Evaluating datasets using Pluto and Plotly
• Building an app using a Dash/Genie framework
• Enabling efficient data processing and analysis

How to Tune a Kalman Filter: Dr. Fredrik Bagge Carlson (JuliaHub Control Systems Team Lead) has published a new blog post, How to Tune a Kalman Filter. “The celebrated Kalman filter finds applications in many fields of engineering and economics. While many are familiar with the basic concepts of the Kalman filter, almost equally many find the "tuning parameters" associated with a Kalman filter non-intuitive and difficult to choose.” Click here for more.

Summary of Julia Plotting Packages: Dr. Chris Rackauckas (JuliaHub Director of Modeling and Simulation) has published a new blog post, Summary of Julia Plotting Packages. Chris reviews Plots, Makie, AlgebraOfGraphics, Gadfly, Vega, VegaLite, Plotly, PlotlyLight,GR, PGFPlotsX, UnicodePlots, Gaston, GMT and GNUPlot.

Julia for Materials Science: A new paper in Nature - Scientific Reports uses Julia to model material properties. Click here to read A Generalized Deep Learning-Based Surrogate Model for Homogenization Utilizing Material Property Encoding and Physics-Based Bounds.

Julia for Cryptography: HUBO and QUBO Models for Prime Factorization is a new paper in Nature - Scientific Reports using Toq.jl for d-wave machines. Click here for more information.

Julia for High Energy Physics Computing: Potential of the Julia Programming Language for High Energy Physics Computing describes how Julia solves the two-language problem for high energy physics computing. “A more convenient and efficient approach would be to use a language that provides both high-level programming and high-performance. The Julia programming language, developed at MIT especially to allow the use of a single language in research activities, has followed this path. In this paper the applicability of using the Julia language for HEP research is explored, covering the different aspects that are important for HEP code development: runtime performance, handling of large projects, interface with legacy code, distributed computing, training, and ease of programming. The study shows that the HEP community would benefit from a large scale adoption of this programming language.”

Julia for Point Process Modeling and Simulation: Extending JumpProcess.jl for Fast Point Process Simulation with Time-Varying Intensities is a new article co-authored by Dr. Chris Rackauckas (JuliaHub Director of Modeling and Simulation). The authors “extended JumpProcesses.jl with a new simulation algorithm, Coevolve, that enables the rapid simulation of processes with locally-bounded variable intensity rates. It is now possible to efficiently simulate any point process on the real line with a non-negative, left-continuous, history-adapted and locally bounded intensity rate coupled or not with differential equations. This extension significantly improves the computational performance of JumpProcesses.jl when simulating such processes, enabling it to become one of the few readily available, fast, general-purpose libraries for simulating evolutionary point processes.”

Julia for Markov Chain Monte Carlo Simulation: Differentiating Metropolis-Hastings to Optimize Intractable Densities is a new article co-authored by Dr. Chris Rackauckas (JuliaHub Director of Modeling and Simulation). The authors “develop a methodology for unbiased differentiation of the Metropolis-Hastings sampler, allowing us to differentiate through probabilistic inference.”
