The Excel Formula Language Is Now Turing-Complete

The Excel team announced LAMBDA, a new feature that lets users define and name formula functions. LAMBDA functions admit parameters, can call other LAMBDA functions and recursively call themselves. With LAMBDA, the Excel formula language is Turing-complete: user-defined functions can thus compute anything without resorting to imperative languages (e.g., VBA, JavaScript).

Benefits of Loosely Coupled Deep Learning Serving

As deep networks are becoming more specialized and resource-hungry, serving such networks on acceleration hardware in tight-budget environments is also becoming difficult. Instead of using API frameworks, loosely coupled components can be preferred as an alternative. They bring high controllability, easy adaptability, transparent observability, and cost-effectiveness when serving deep networks.

Obscuring Complexity

One of the most important things that software architects do is manage the complexity of their systems in order to mitigate release disruption while maintaining sufficient feature velocity. When we cannot reduce complexity, we try to hide or shift it. Software architects tend to manage that complexity with the time-honored strategies covered in this article.
