A few days ago Ben Werdmuller asked what the biggest problem to be solved in software is. I suggested 'documentation' (and I stand by that). But this is a good one too. He writes about the 'pull request', which is a standard part of software development. Essentially, the idea is that new code can be reviewed before it is added to a project. But maybe - suggests Werdmuller - there needs to be wider oversight. "Pull requests, in their current form, encourage teams to take a code-first approach without considering the human impact or social context of their work," he writes.
