Git at any scale
Hosting Git repositories at scale is a nightmare. When Linus Torvalds designed the first version of the information manager from hell (that's actually the tagline for Git, look it up ), he had a very specific use case in mind: his own. He wanted to replace BitKeeper, the distributed version control system that was…

Making Facebook's native mobile app faster using HTML5
When we started what became Sencha, we made a bet on the web: a bet that modern application development didn’t need anything except the browser, a great set of frameworks and a great set of tools. With those three weapons in hand, we knew developers could build applications that would delight users.

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…

Context Rot: How increasing input tokens impacts LLM performance
Large Language Models (LLMs) are typically presumed to process context uniformly—that is, the model should handle the 10,000th token just as reliably as the 100th. However, in practice, this assumption does not hold. We observe that model performance varies significantly as input length changes, even on simple tasks…

Why Constant-Time Crypto?
In 1996, Paul Kocher published a novel attack on RSA, specifically on RSA implementations , that extracted information on the private key by simply measuring the time taken by the private key operation on various inputs. It took a few years for people to accept the idea that such attacks were practical and could be…
