Developer Ecosystem Survey 2019: Raw Data Available

To monitor the rapidly changing State of the Developer Ecosystem, we, at JetBrains every year conduct a comprehensive survey to represent the developers in the world.

Earlier this year we presented the results of the research in our Developer Ecosystem Infographic. You can find plenty of interesting charts and facts we have carefully prepared for you in it. But imagine, how many hidden insights the data may still contain. The survey consisted of more than 300 questions in addition to the ones presented in the infographic.

The Raw Data is In

Now, as usual, we are publicly sharing the raw data of the survey responses. So you can dig deeper and find your own amazing facts. Via the link, you can find the survey questions and survey logic as well.

To reduce possible bias, only the responses from advertisements and referrals were included in the Infographics (which is about 7,000 respondents), while this shared dataset includes all the 19,000+ responses collected from both internal and external channels.

Please keep in mind that your figures might be different from what we have in the report as we applied weighting to our data. For more information check the Methodology section.

The data are anonymized, with no personal information or geolocation details. Moreover, to prevent the identification of any individual respondents by their verbatim comments, all open-ended fields are omitted. We have also merged any answer options that collected fewer than 15 responses into the “Other” answer option. Via the link, you can find the survey questions and survey logic as well.

If you have any questions regarding the survey or data please contact us at

Data Science Survey 2018: Raw Data Available

In the spring of 2018, we conducted the Data Science survey where we asked people from all over the world working with data to tell us about their work, tools, and practices. We distributed this survey via targeted ads on Facebook, LinkedIn, and Twitter to reduce any possible bias in the results towards our JetBrains audience. We collected about 400 sets of responses from the USA, Japan, and China, and used quotas to get another 400 responses from European countries.

The main results of the research are presented in our Data Science 2018 infographics. And now we’ve also made the raw data available for download.

Data Science Survey 2018: Raw data available

To make the data more discoverable and easier to analyze, we’ve created a dataset on the Kaggle platform. This dataset is distributed under a Creative Commons Attribution 4.0 license. We’ve also prepared a kernel with a set of useful functions that may help you analyze the data.

Go ahead, start digging into the data, and don’t forget to join our Survey Panel!

The Drive to Develop

P.S. To start working with the dataset (e.g. download the data or copy and edit the kernel), you have to be registered on Kaggle. It’s free.

An Interview with Jakub Chrzanowski, .ignore Plugin Author

In this interview, we speak with Jakub Chrzanowski (@hsz @hszanowski), the author of the .ignore plugin for the IntelliJ-based IDEs. This plugin lets you mark matched .ignore files in project view, assists with editing them, and helps you generate ignore rules using templates.

Welcome, Jakub! Before we get started, could you please tell us a bit about yourself and your background?

I started my development journey in primary school with Pascal. I had strong support from my teacher and his code listings from a dot-matrix printer. That was a very exciting beginning for a young fellow and sometimes I miss it a bit. Over the next 18 years, I explored some other programming languages like C, Perl, Java, PHP, and C# and ending, for now, with NodeJS, TypeScript, and Kotlin. My focus has mainly been on the web development and DevOps with a touch of JetBrains plugins crafting in my free time.

Jakub Chrzanowski

What is the .ignore plugin and how did it come about?

The .ignore plugin is a tool that helps developers handle .gitignore files in a more complex format than just a plain text file with some glob-like rules. The main features of the plugin are:

Welcome EduTools plugin v2.7: YAML support, Algorithmic Toolbox by Coursera, and more

Our newest plugin update to v2.7 comes with YAML support for course creators, multiple-choice task support, new courses, and 2019.1.2 IDE builds for PyCharm Edu and IntelliJ IDEA Edu.


YAML support

Course creators, welcome a completely reworked solution for course configuration files storage! Previously, all course metadata was stored in XML format. Now you can see all the information about your course conveniently stored in YAML format. We worked hard to make this possible and we hope that you will like the YAML support as much as we do.

Get More Out of Your JetBrains Tools with Commercial Third-party Plugins From the JetBrains Marketplace

With more than 4,000 available plugins, the Plugins Repository is able to deliver a variety of third-party plugins that can extend your JetBrains product on demand. There are plugins to bring you everything from additional languages and new technology support to cloud integrations, to themes, learning shortcuts, and even a Nyan Cat progress bar. Plugins for pretty much all the JetBrains tools including, but not limited to, all the IntelliJ–based IDEs, TeamCity, and .NET tools.

Today we want to introduce to you the brand-new JetBrains Marketplace platform, a new evolutionary step for the Plugins Repository. This new platform provides an opportunity for third-party plugin developers to sell and license their plugins using an out-of-the-box solution provided by JetBrains. With this platform addition, more developers will be able to dedicate more of their “official working time” to plugin development on a longer-term basis, as sometimes it can be challenging to invest and dedicate so much of their time to when it doesn’t help towards paying the bills.

Third-party plugin developers won’t need to invest their time into their own licensing solutions and creating the sales workflows themselves anymore. What this means for you, as plugin users, is that you can enjoy even more feature-full high-quality plugins to help you develop with pleasure.

JetBrains Security Bulletin Q1 2019

This bulletin summarizes the security vulnerabilities detected in JetBrains products and remediated in the first quarter of 2019.

These include issues reported by Jonathan Leitschuh potentially exposing a product user or a project’s infrastructure to man-in-the-middle attacks, namely

  • resolving Gradle, Maven, and sbt project artifacts over an unencrypted connection in various projects; and
  • generating project templates in an IDE causing the above-mentioned issue in a user’s project.

We’ve also run extended verification of the secret storage mechanism in our IDEs’ settings, and identified and fixed several cases of cleartext secret storage.

Here’s a summary report that comprises the affected product, the description of each issue, its severity, and the product version containing the fix.

What’s New in Toolbox App 1.15

TL;DR: JetBrains Account integration, automatic plugins update, GitLab and BitBucket integration, improved performance, and bug fixes.

Toolbox App 1.15 is released

We are happy to tell you that the Toolbox App is now being used by over 440,000 users. We appreciate your loyalty and trust and would love to hear from you here in the comments or on Twitter mentioning @JBToolbox on which features we need to include to make your experience with the Toolbox App even better.

Here is an overview of the latest improvements to the Toolbox App.

JetBrains Account integration

The Toolbox App now uses OAuth to authenticate you in the JetBrains Account. This has a lot of benefits:

Single Sign-On: log in to your JetBrains Account once in your favorite browser and then approve the Toolbox App to access this account. There is no longer any need to enter your credentials again.

License information: the Toolbox App now lets you quickly buy a license if it can’t find one for your account. Just click on the “Buy” button and go straight to the store page.

Improved Security: the Toolbox App only has access to a limited scope of account data, and the access can be revoked at any time.

Toolbox App Security

Plugins update automatically

With Toolbox App 1.15, plugins are now stored alongside the IDE and are updated automatically together with the IDE, saving you time and removing the need for additional manual actions.
You may notice an additional “Updating plugins…” step during the installation. Since every build now has a separate plugin directory, the update is possible even when another build is running.
