Version SAT
The package version selection problem is to find a set of dependencies that can be used to build a top-level package P that is complete (all dependencies satisfied) and compatible (no two incompatible packages are selected). There may be no such set, because of the diamond dependency problem: perhaps A needs B and C…

Differentiable Neural Computers
In a recent study in Nature, we introduce a form of memory-augmented neural network called a differentiable neural computer, and show that it can learn to use its memory to answer questions about complex, structured data, including artificially generated stories, family trees, and even a map of the London Underground…

Why are the Microsoft Office file formats so complicated? (2008)
Last week, Microsoft published the binary file formats for Office. These formats appear to be almost completely insane. The Excel 97-2003 file format is a 349 page PDF file. But wait, that’s not al…

Subresource Integrity Addressable Caching

Taking PHP Seriously
Slack uses PHP for most of its server-side application logic, which is an unusual choice these days. Why did we choose to build a new project in this language? Should you? Most programmers who have only casually used PHP know two things about it: that it is a bad language, which they would never use if…
