Introduction
When I started my 20% project – an initiative where employees are allocated twenty-percent of their paid work time to pursue personal projects – with Project Zero, I wanted to see if I could apply the techniques I had learned fuzzing Chrome to XNU, the kernel used in iOS and macOS. My interest was sparked after learning some prominent members of the iOS research community believed the kernel was “fuzzed to death,” and my understanding was that most of the top researchers used auditing for vulnerability research. This meant finding new bugs with fuzzing would be meaningful in demonstrating the value of implementing newer fuzzing techniques. In this project, I pursued a somewhat unusual approach to fuzz XNU networking in userland by converting it into a library, “booting” it in userspace and using my standard fuzzing workflow to discover vulnerabilities. Somewhat surprisingly, th

Sourcegraph on Wednesday launched Batch Changes, an automated internal coding tool that allows enterprises to automate and track large-scale code changes across all repositories and code hosts. For software developers, this is game changing.
This new tool also provides developers and enterprises with an easy way to manage the resulting change sets through checks and code reviews so they can be confident each change is merged.
Last year, over 800,000 developers used Sourcegraph to search and understand their code. In the same way that big data has disrupted data teams, big code is creating hurdles for enterprise engineering teams who struggle to navigate and make changes across increasingly large and complex codebases, according to Sourcegraph.
