But outdated security practices pose a significant barrier even to the most efficient DevOps initiatives. We also quickly check for system events and see there were no scheduled code deploys in the last week. PoCs are incredibly powerful as an exercise we do WITH our customers, rather than TO them.

Efficiency, not human flourishing, is maximized. Governance is not a “once and done” exercise. In his book Voices in the Code , James G. There is no perfectly efficient algorithm that gets everything right. The design of an AI that will not destroy us may be the very thing that saves us in the end.

This abstraction allows the compute team to influence the reliability, efficiency, and operability of the fleet via the scheduler. We do this for reliability, scalability, and efficiency reasons. Let’s go back to that kernel code example earlier. The hosts that run workloads are called Titus “agents.” User Namespaces.

Video encoding is what MezzFS was originally designed for and remains one of its canonical use cases, so we’ll focus on video encoding to describe the problem that MezzFS solves. MezzFS collects metrics on data throughput, download efficiency, resource usage, etc. What problem are we solving? Its logs are collected in an ELK stack.

If you peek under the hood of an ML-powered application, these days you will often find a repository of Python code. Let’s start by considering the job of a non-ML software engineer: writing traditional software deals with well-defined, narrowly-scoped inputs, which the engineer can exhaustively and cleanly model in the code.

Millions of lines of code comprise these apps, and they include hundreds of interconnected digital services and open-source solutions , and run in containerized environments hosted across multiple cloud services.

" The eventual Blink fork was precipitated by an insurmountable difficulty in doing precisely what Apple suggested to Congress: contributing code upstream to WebKit to enable new features. It's worth assessing these claims from most easily falsified to most contested.

In some cases, if only a very few, these assets continue to be used because they still work very well, were thoughtfully designed, and have been well cared for over the years. The exercise of assessing, modeling and dispositioning the landscape does offer valuable new ways of looking at legacy assets.

We developed a friendly competition to break one another’s code. We are a bit wiser (you could take that as older) now and we don’t wait until 5 o’clock but we still try everything we can think of to exercise the code.

Circa '07, those web apps were notably slower than native code could be.

We have to specify with great precision in code exactly what our business rules are, and the computer will apply them exactly as we tell it to. Domain-Driven Design’s Aggregate pattern is used to bridge the gap. It acts as a collaboration tool to balance the need for business correctness, user experience, and technical efficiency.
