GitHub unveils the state of open source 2018


Code hosting and collaboration platform GitHub has released its Octoverse 2018 report, providing statistics and insights on global software development trends – revealing Microsoft under Satya Nadella was by far the number one contributor to open source this year.

In 2018 — which also happens to be GitHub’s 10th anniversary year — more than 1.1 billion code contributions were made to the global platform, which has transformed a simple home for open source projects into “social coding”, allowing developers worldwide to inspire and build from each other in the pursuit of solving real problems.

The Octoverse report, released on Wednesday at GitHub Universe in San Francisco, reveals over 31 million developers are now registered with GitHub, from 2.1 million organisations, and with 96 million repositories hosted on the site.

The number of organisations and repositories have increased 40% since 2017, and the number of new GitHub users in 2018 — eight million — is as many in one year as the first six years’ of GitHub’s operations combined.

Over 200 million pull requests have now been made on the site — “conversations around code,” GitHub calls them — with more than one third in 2018 alone.

Most GitHub users — about 80% — come from outside the US. Not surprisingly, the individual country with the most contributors remains the US. However, China and India (two and three, respectively) have increased their ranking, as has Brazil (now ranked seven, up from tenth in 2017.) Australia comes in 12th, ahead of Spain.

GitHub is seeing new growth among organisations in non-English speaking countries, with Saudi Arabia increasing 2.2 times from 2017, followed by Nigeria (2.1x) and Egypt, Venezuela and Indonesia.

Similarly, the fastest increase in public and private repositories is in Algeria, with a 2.3 factor increase from 2017, followed by Hungary (2.1x) and Egypt (2x).

No matter where people live, or whether they worked on public, private or open source repositories, GitHub found a universal trend of developers actively working on their code until 10 pm.

While work continues on the weekend, globally a drop on private repositories occurs when weekends arrive. Projects similarly scale back around major holidays.

People aside, the top 10 open source projects by the number of unique contributors has been revealed as:

  1. Microsoft/vscode
  2. facebook/react-native
  3. tensorflow/tensorflow
  4. angular/angular-cli
  5. MicrosoftDocs/azure-docs
  6. angular/angular
  7. ansible/ansible
  8. kubernetes/kubernetes
  9. npm/npm
  10. DefinitelyTyped/DefinitelyTyped

When it comes to the greatest number of contributions to open source projects, the results are something that was unthinkable when GitHub launched 10 years ago:

  1. Microsoft, with 7,700 contributions
  2. Google – 5500
  3. Red Hat – 3300
  4. UC Berkeley – 2700
  5. Intel – 2200

Language-wise, JavaScript remains the number one language, while TypeScript has jumped three spots from its number 10 place in 2017, and is now the seventh most popular language on GitHub. It experienced this popularity across every region.

The top emoji, you ask? It turns out GitHubbers are an encouraging lot, with thumbsup the most-used emoji out of all reactions, followed by dada, heart, laugh and eventually thumbsdown and frown in fifth and sixth places. Contributors to Ruby offered the highest percentage of heart emojis.

Additionally, GitHub stated over five million vulnerability alerts were issued during 2018, and more than 800,000 had been resolved.
