Introducing Machine Learning Practica

https://blog.google/topics/machine-learning/introducing-machine-learning-practica/ When I was a graduate student in cognitive science, I spent countless hours poring over videos and transcripts of natural language, looking for patterns in the data that could help me better understand how people learn words, concepts, and categories. Fast forward a few years, and I’m now a part of Google’s machine learning education team. We support the company’s mission to make AI beneficial to everyone by helping educate Googlers and others on how to build machine learning (ML) models that look for patterns in data in order to solve a variety of problems. Back in February, our team shared our internal Machine Learning Crash Course (MLCC) with the world to help more developers learn to use ML. Since then, we’ve heard from many people who are hungry for more ML education. In particular, you want to learn from teams who have built and deployed ML models. What challenges and successes do pr

What is Digital Twin Technology? A Real-World Example

https://www.verypossible.com/blog/what-is-a-digital-twin-an-engineers-guide As an engineer, I try to ignore the marketing hype until something becomes relevant to me. So when a member of our marketing team asked me if I knew anything about "digital twin" technology, I admitted I had never heard of it. However, after a Google search, it quickly became obvious that I had been practicing and even advocating for digital twin technology for nearly a decade. So now, I'd like to add some concrete math and code to the "Digital Twin" hype, I'll go through a simple pedagogical example that is based around a standard undergraduate mechanical engineering concept. All units will be in metric (because science). The Jupyter Notebook , which I used to run the simulations and generate all the charts, can be found here . Simplified Automotive Suspension (AKA Mass-Spring-Damper System)   The mass-spring-damper system above is governed by the

ZFS New Rule of Thumb

ZFS New Rule of Thumb About ZFS Performance https://www.percona.com/blog/2018/05/15/about-zfs-performance/ So, let’s proposed a new rule of thumb for the required ARC/L2ARC size for a a given dataset: Recordsize of 128KB => 0.1% of the uncompressed dataset size Recordsize of 64KB => 0.2% of the uncompressed dataset size Recordsize of 32KB => 0.4% of the uncompressed dataset size Recordsize of 16KB => 0.8% of the uncompressed dataset size

The Importance of Deep Work & The 30-Hour Method for Learning a New Skill

https://azeria-labs.com/the-importance-of-deep-work-the-30-hour-method-for-learning-a-new-skill/ The tech industry, especially the security industry, seems outrageously overwhelming to newcomers and even as an intermediate “InfoSec Pro” there seems to be an overwhelming number of paths and topics one can focus on. The problem most of us, especially newcomers, encounter is that we don’t know what to focus on. Even when we find a topic to focus on, we seem to get stuck in the vast pool of resources that are available to us. Take the GitHub repository Awesome Hacking  (highly recommended), for example. Many people are aware of its existence. The very same people are sending me messages and asking where to start and how to not be totally overwhelmed by what seems to be a structured collection of valuable resources but doesn’t seem to solve our problem. But what exactly is our problem? It’s certainly not the lack of resources. Why is it, that although we have access
