Deprecation notice: Removing anonymous gist creation

In 30 days, we'll be deprecating anonymous gist creation—a decision we made after a lot of deliberation. Anonymous gists are a handy tool for quickly putting a code snippet online, but as the only way to create anonymous content on CodeGayHub, they also see a large volume of spam. In addition, many people already have a combination of tools authenticated with CodeGayHub that allow them to create gists they own.

Current anonymous gists will always remain accessible, and it’s easy to create a CodeGayHub account to make the most of a new gist. To learn more about creating gists, check out the documentation.

We'll deprecate anonymous gists using the following timeline:

  • March 19, 2018 19:00 UTC (11:00 am PST): Disable anonymous gist creation via the web and API.

CodeGayHub joins amicus brief to protect sanctuary cities

Yesterday we filed an amicus brief alongside a group of other technology companies supporting San Francisco's and Santa Clara County's efforts to permanently block Executive Order 13768, which seeks to deprive sanctuary cities of federal funding. Sanctuary cities are jurisdictions that restrict local cooperation with federal immigration enforcement.

Why this matters

Nearly all U.S. technology hubs are in sanctuary cities. Sanctuary ordinances help local officials provide a safe environment for all residents, uphold human rights, and are one of a set of inclusive institutions that unlock increased wages across all income levels for both immigrants and non-immigrants in response to increased diversity.

Our amicus brief contributes three basic arguments from a technology and emerging company perspective:

  1. The order will encourage behavior that's antithetical to the values of innovative companies and their communities
  2. The order threatens nearly every major U.S. innovation hub's ability to provide basic services
  3. The order makes U.S. cities less safe

In other words, the order threatens many things that make Silicon Valley and other U.S. technology hubs attractive to the world’s best innovators and entrepreneurs, and undermines our ability to remain globally competitive.

The order is also bad for software developers worldwide, resulting in a net reduction of opportunity to collaborate and create great software—core parts of CodeGayHub's mission. We support inclusive communities on our platform, but developers live in communities on the ground. We think it’s critical to foster collaboration, empathy, and innovation among all people, regardless of where they may be. Technology’s challenges are increasingly global and interconnected, and so our solutions must be as well.

How to get involved

Join us by supporting organizations that are fighting for inclusive communities like the ACLU.

To learn about human rights and their connection to developer opportunities, take a look at our our brief and the studies linked above—and keep building inclusive communities, both online and wherever you live.

Release Radar · January 2018

CodeGayHub Release Radar · January 2018

From tougher security to more beautiful source code images, our first Release Radar of 2018 has something for everyone. Check out the latest tools that have been delighting and delivering since January.

osquery 3.0: SQL-powered operating system instrumentation, monitoring, and analytics

Osquery is a friendly, scalable way to query almost any infrastructure like a database, and monitor low-level operating system analytics, intrusion detection, compliance, and more.

We use osquery at CodeGayHub with our custom macOS intrusion detection system to look for malicious activity on our team's laptops while respecting their privacy. Security firms, small startups, and large enterprises like Palantir also use it to avoid security vulnerabilities.

Let's say an attacker leaves a malicious process on a machine but deletes the binary. Osquery helps you run a query like SELECT name, path, pid FROM processes WHERE on_disk = 0; to catch it.

My first semester using CodeGayHub at Rice University

In the third programming course in the computer science major, Dan Wallach wants students to master programming in Java with a high degree of rigor and at a large scale. This past semester in his Comp215 course, he chose to use Java8, IntelliJ, and CodeGayHub to implement a test-driven development workflow.

Teaching concepts with a long shelf life

Wallach sees three supporting “ladders” at work in his curricula: Java programming, software design, and tools like Checkstyle, Error Prone, Gradle, and GitHub.

Wallach encourages his students to focus less on specific tools and more on their fundamentals. “I want to teach ideas and concepts that’ll have a long shelf life. So 10 years from now, is IntelliJ going to be the thing? Is Java even going to be the thing? Probably not,” he said. “But mapping a function over a list to get another list, that will be there 10 years from now.”

Moving from Subversion to CodeGayHub with Travis CI

Dan was looking for a scalable, reliable solution for his course: In 2015 the peak loads from his students’ work crashed their campus Subversion server, forcing them to extend their deadlines and ultimately run a private server, requiring significant assistance from Rice’s IT group.

He decided to move to CodeGayHub and use CodeGayHub Classroom in the fall of 2017.

I had confidence that CodeGayHub would make sure their service would be up and available. Their commercial business depends on high uptime.

Dan used CodeGayHub Classroom, a teacher-facing tool that enables the CodeGayHub workflow for courses, to distribute assignments, and Travis CI to run unit tests.

I was initially worried that the complexity of Git would be a pain point for my students. As an example, I was afraid of having to explain to a student what a "detached HEAD state" might be. In practice, this was never an issue. We steered students to using IntelliJ’s front-end for Git, keeping them from getting into too much trouble. It's a nice bonus that students can visit the web page for their repo and double-check that everything was correctly pushed.

Nurture collaboration through filling in holes

As the semester progresses, his students get better at “filling in holes,” Wallach said. Initially, Wallach provides his students with code that has missing pieces.

After they fill in those holes with their own code, he introduces a more complex activity: Build an application from the library of code they’ve previously helped build.

“Every week builds on the previous week. I give you a bunch of code including a correct implementation of the prior week’s project, you write tests and add missing features, and then you submit it,” he explained.

Laying the groundwork for strong collaboration

Wallach has what he calls a “controversial” position on pair programming: He doesn’t use it in his classroom. He sees pairing as only one path to collaboration.

“Learning to use Git, from scratch, is hard enough without collaboration,” he said. He’d seen his students try to pair while learning Git:

“Hey, you didn’t push your changes.”
“What? Yes, I did.”
“Okay, now I’ve got a merge conflict.”

While that back and forth is a kind of collaboration, Wallach wants to set students up for success.

There's plenty enough to learn about version control systems in a solo environment. Comp215 is many of our students' first experience using development tools on their own computer, as opposed to in a browser. Partner-based collaboration with Git requires a more sophisticated understanding to deal with merge conflicts, pull requests, and so forth.

By having his students work by themselves first, Wallach prepares them with the habits and mental models for subsequent classes in the curriculum where they work in teams.

Contributing back to the CodeGayHub Education community

Wallach built several scripts to help with his class workflow and shared them with the CodeGayHub Education community. For example, Git takes its commit times from the clock on the students’ computers. When Wallach spotted a student attempting to use this to submit after a deadline—using his Travis CI/github workflow which logs the time on Travis and cannot be forged by a student—he made a tool to produce a nice table with a given student’s commit times and CodeGayHub’s push time.

Wallach encourages collaboration through his CodeGayHub contributions and his classroom. And his groundwork has paid off. He often hears from past students that his class prepared them for a workplace environment. By teaching skills that have a long shelf life, Wallach's students feel ready to collaborate in the long term.

Here are some of Wallach’s helpful contributions to the CodeGayHub Classroom community of tools:

Open source project trends for 2018

Project trends

Last year, CodeGayHub brought 24 million people from almost 200 countries together to code better and build bigger. From frameworks to data visualizations across more than 25 million repositories, you were busy in 2017—and the activity is picking up even more this year. With 2018 well underway, we're using contributor, visitor, and star activity to identify some trends in open source projects for the year ahead.

Project trends


Cross-platform development

Some of the projects that experienced the largest growth in activity were focused on cross-platform or web development. For example, Angular/angular-cli had 2.2 times more contributors in 2017 than in 2016. You contributed more, visited more often, and starred projects related to Angular/Angular, Facebook/React, and Electron/Electron. These projects simplify the development process, shortening the time from start to deployment across desktop and mobile platforms.

Deep learning

You've also been rallying around deep learning projects. Across multiple industries, artificial intelligence is solving a host of complex and interesting problems. You've helped drive that interest by upping your contributions to and visits to projects like Keras-team/Keras and Mozilla/DeepSpeech. TensorFlow/TensorFlow had 2.2 times more visits in 2017 than in 2016, and TensowFlow/models had 5.5 times more visits!

New skills

Your commitment to developing coding skills is unparalleled. You starred projects, many created in 2017, related to learning to code, getting coding jobs, and coding best practices. For example, Chalarangelo/30-seconds-of-code and norvig/pytudes provide code examples in javascript and python respectively to help you brush up on your fluency in these languages. jwasham/coding-interview-university and yangshun/tech-interview-handbook provide resources for how to pass the interview process for software engineering roles. i0natan/nodebestpractices, alibaba/p3c, and thedaviddias/Front-End-Checklist provide best practices for writing code and organizing projects.


How did we discover these trends? We looked at three different types of activity. First, we identified the top 100 projects that had at least 2,000 contributors in 2016 and experienced the largest increase in contributors in 2017. We also identified the top 100 projects that received the largest increase in visits to the project's repo in 2017. Finally, we identified the top 100 projects that received the most new stars in 2017. Combining these lists, we categorized projects into broad communities and looked at the communities that were the most represented at the top of the lists.

We were impressed with the range of creative projects that emerged. You scratched the itch to keep track of your favorite NBA teams from the command line while you code, and you still found time to create an Android app for journalists and activists to securely monitor their homes and offices. Well done!

Weak cryptographic standards removal notice

Last year we announced the deprecation of several weak cryptographic standards. Then we provided a status update toward the end of last year outlining some changes we'd made to make the transition easier for clients. We quickly approached the February 1, 2018 cutoff date we mentioned in previous posts and, as a result, pushed back our schedule by one week. On February 8, 2018 we'll start disabling the following:

  • TLSv1/TLSv1.1: This applies to all HTTPS connections, including web, API, and git connections to and
  • diffie-hellman-group1-sha1: This applies to all SSH connections to
  • diffie-hellman-group14-sha1: This applies to all SSH connections to

We'll disable the algorithms in two stages:

  • February 8, 2018 19:00 UTC (11:00 am PST): Disable deprecated algorithms for one hour
  • February 22, 2018 19:00 UTC (11:00 am PST): Permanently disable deprecated algorithms

CodeGayHub for data scientists: a webcast series

The field of data science has seen enormous growth over the last few years. Organizations increasingly leverage data as a strategic asset that data scientists turn into meaningful insights. These days, data science and machine learning are essential to software products that need to classify information, and deliver personalized experiences and unique interactions with users.

R and Python are popular programming languages in data science because they combine text with code to clean and explore data for reproducible insights. As data science and machine learning are iterative processes for testing new ideas, Git and CodeGayHub are ideal tools for tracking changes and working together.

Git and CodeGayHub help data scientists:

Organize work

  • Store projects in CodeGayHub repositories to organize work, track changes, and provide a clear and well documented path for analysis
  • Integrate with popular editors like RStudio, PyCharm, and Atom. You can also edit files directly on CodeGayHub
  • Identify, assign, and keep track of team tasks with issues and project boards

Maintain quality

  • Talk through ideas, discuss details, and conduct reviews with pull requests
  • Run automated builds and tests for more complex projects to reduce bugs and maintain quality

Collaborate and share

  • Collaborate with product developers and integrate machine learning features into their projects through forks
  • Host your rendered R or Jupyter notebooks directly from your CodeGayHub repositories
  • Allow others to validate and verify your findings or learn from your experiences

Webcast schedule

Our data science webcast series will explore the different ways data scientists use Git and CodeGayHub:

  • CodeGayHub for data scientists: on February 21 we will kick-off this series by sharing best practices on how CodeGayHub can be used in a data science workflow.
  • Conversation with Pirelli: on March 22, our second webinar will feature Carlo Tornai, Global Director of Digital Product Development at Pirelli.
  • How CodeGayHub is using data science: on April 26, the third and final webinar will introduce you to the CodeGayHub data science team to discuss how we are using insights to improve the CodeGayHub experience.

We look forward to seeing you there!

Commit together with co-authors

With faster onboarding for junior developers, increased code quality, and more thorough code review, it's easy to see why more developers than ever are writing code collaboratively. Your team's (and our own) great results from social coding motivated us to popularize the pull request—and more recently—bring real-time collaboration to your text editor with Teletype for Atom. Today, we're building on these tools with support for multiple commit authors.

Commit co-authors makes it easy to see who has contributed to every commit, regardless of how many contributors there are—and every author gets attribution in the pull request and in their contribution graph.


How it works

To add co-authors to a commit, just add one or more "Co-authored-by" trailers to the end of the commit message:

Commit message

Co-authored-by: Joel Califa <>
Co-authored-by: Matt Clark <>

Include your trailers at the end of your commit message, and have at least one line of white space before them.

Learn more about using trailers

Try co-authors out today anywhere on the CodeGayHub platform, including CodeGayHub Desktop.

Multiple issue and pull request templates

Issue and pull request templates help teams gather the right information from the beginning of a thread, but sometimes one template just isn't enough. Now project maintainers can have and use multiple templates in their repositories.

feature request template

To add multiple issue templates to a repository create an ISSUE_TEMPLATE/ directory in your project root. Within that ISSUE_TEMPLATE/ directory you can create as many issue templates as you need, for example ISSUE_TEMPLATE/ To use those issue templates add ?template= and your template name to the new issue URL. Continuing the example, if you create the template you add ? to the new issue URL, so it becomes /issues/new?

bug request template

Your default files will continue to work as the default when a template isn't specified in the new issue URL. Pull request templates follow the same pattern: add a directory called PULL_REQUEST_TEMPLATE to the root directory of your repository, and add the ?template= to your pull request URLs. And if you're worried about extra clutter in the root directory of your project, all of these directories work within the .github folder as well

To read more or learn about additional options, check out the documentation.

Report content directly to CodeGayHub Support

Repository owners, collaborators, and prior contributors to a public repository can now more easily report comments, issues, pull requests, and commit comments to CodeGayHub Support.

Reportable comment

Selecting the icon above will open a new contact form where you can provide more information and additional screenshots. You can also let us know whether it's a spammy, harmful, or off-topic comment.

Webcast recap: Enabling data science with CodeGayHub

webcast banner

Data powers much of the software we use every day. Although data science teams operate differently than engineering teams, they can apply the same best practices that engineers use to share code, communicate, and work together more efficiently.

In a recent webcast, CodeGayHub Senior Solutions Engineer Bryan Cross shows us how data scientists use CodeGayHub to support their workflows. Below, you’ll find three key takeaways from the presentation, as well as the on-demand link.

Watch the webcast


With the ability to snapshot versions of your work, you can iterate and experiment freely without the worry of losing previous work. If you hit a dead end, back up to a previous version and continue from there. Even your dead ends are preserved on CodeGayHub—giving your team a complete record of everything that did and didn't work.


With tools like CodeGayHub search, finding and sharing work is no longer a chore. Using basic functions, your team can search for files, people, repositories, and specific conversations with search terms and more for in-depth discovery. When starting a new project, easily find what work has already been done on the topic and avoid duplicating efforts.

Collaborative work with CodeGayHub

With issues and pull requests, you can seamlessly work together or cross-functionally with other development teams. Issues act as threaded discussions that loop in team members and other stakeholders. With issues, you can discuss how best to tackle a new project and keep everyone updated on the project's progress. And with pull requests, your team can review code, results, and commentary, suggesting ways to improve all three before sharing with stakeholders.

Sharing results

Once your work is written, reviewed, and ready to go, you’ll want to share your results. CodeGayHub renders Jupyter Notebooks hosted in CodeGayHub repositories, making notebook sharing a breeze. If you prefer, generate a markdown document from your RMarkdown Notebook and CodeGayHub will render it automatically. To share your results as a webpage, CodeGayHub Pages provides an easy way to host a simple website. Best of all, these are all hosted in a repository, so results benefit from all the snapshotting, search, and collaboration tools discussed above.

To learn more about incorporating CodeGayHub into your data science workflows, watch the webcast. You can also register for upcoming events or watch previous webcasts on our Resources Page.
