- Dynamo and BigTable — good preso overview of two approaches to solving availability and consistency in the event of server failure or network partition.
- Goals Gone Wild (PDF) — In this article, we argue that the beneficial effects of goal setting have been overstated and that systematic harm caused by goal setting has been largely ignored. We identify specific side effects associated with goal setting, including a narrow focus that neglects non-goal areas, a rise in unethical behavior, distorted risk preferences, corrosion of organizational culture, and reduced intrinsic motivation.

ENTRIES TAGGED "distributed"
How do we manage systems that are too large to understand, too complex to control, and that fail in unpredictable ways?
“What is surprising is not that there are so many accidents. It is that there are so few. The thing that amazes you is not that your system goes down sometimes, it’s that it is up at all.”—Richard Cook
In September 2007, Jean Bookout, 76, was driving her Toyota Camry down an unfamiliar road in Oklahoma, with her friend Barbara Schwarz seated next to her on the passenger side. Suddenly, the Camry began to accelerate on its own. Bookout tried hitting the brakes, applying the emergency brake, but the car continued to accelerate. The car eventually collided with an embankment, injuring Bookout and killing Schwarz. In a subsequent legal case, lawyers for Toyota pointed to the most common of culprits in these types of accidents: human error. “Sometimes people make mistakes while driving their cars,” one of the lawyers claimed. Bookout was older, the road was unfamiliar, these tragic things happen. Read more…
Distributed Browser-Based Computation, Streaming Regex, Preventing SQL Injections, and SVM for Faster Deep Learning

- Deep Learning Using Support Vector Machines (Arxiv) — we are proposing to train all layers of the deep networks by backpropagating gradients through the top level SVM, learning features of all layers. Our experiments show that simply replacing softmax with linear SVMs gives significant gains on datasets MNIST, CIFAR-10, and the ICML 2013 Representation Learning Workshop’s face expression recognition challenge.

- An API Ontology — I currently see most real-world deployed APIs fit into a few different categories. All have their pros and cons, and it’s important to see how they relate to one other.
