Devops Best Practices Checklist

Find the original here article here: Devops Best Practices

DevOps started out as "Agile Systems Administration". In 2008, at the Agile Conference in Toronto, Andrew Shafer posted an offer to moderate an ad hoc "Birds of a Feather" meeting to discuss the topic of "Agile Infrastructure". Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing

Libraries and Tools for React

If you're developing an application based on React it can be helpful if you don't need to develop all the basic UI components yourself. Here you can find a list with various components, component libraries and complete design systems developed with and for React.

As the list got longer and longer I thought it would be better to have a "real" site for it.

👉 Please find the (new) list here: https://react-libs.nilshartmann.net/

Reinforcement Learning from Human Feedback (RLHF) - a simplified explanation

Maybe you've heard about this technique but you haven't completely understood it, especially the PPO part. This explanation might help.

We will focus on text-to-text language models 📝, such as GPT-3, BLOOM, and T5. Models like BERT, which are encoder-only, are not addressed.

Reinforcement Learning from Human Feedback (RLHF) has been successfully applied in ChatGPT, hence its major increase in popularity. 📈

RLHF is especially useful in two scenarios 🌟:

  • You can’t create a good loss function
    • Example: how do you calculate a metric to measure if the model’s output was funny?
  • You want to train with production data, but you can’t easily label your production data
