rr aspires to be your primary debugging tool, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time.

rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit.

rr works on real applications such as Firefox, with low overhead. It is being used by many developers inside and outside Mozilla to fix real bugs.

Counting bits (popcount), swapping bytes/endian (bswap32) and other compiler intrinsics.

The metric we all use for CPU utilization is deeply misleading, and getting worse every year. What is CPU utilization? How busy your processors are? No, that's not what it measures. Yes, I'm talking about the "%CPU" metric used everywhere, by everyone. In every performance monitoring product.

"The JavaScript Way" is a book to help you get off to a good start in the JavaScript universe or catch up with its newest evolutions. Here are some highlights:

Deep Reinforcement Learning Papers

Tensorflow + Keras + OpenAI Gym implementation of 1-step Q Learning from "Asynchronous Methods for Deep Reinforcement Learning"

Summary of what's new in Java 8.

Turn your two-bit doodles into fine artworks with deep neural networks, generate seamless textures from photos, transfer style from one image to another, perform example-based upscaling, but wait... there's more! (An implementation of Semantic Style Transfer.)

The guidelines were introduced during a number of talks at CppCon 2015.

netdata is a scalable, distributed, real-time, performance and health monitoring solution for Linux, FreeBSD and MacOS. It is open-source too.

A complete computer science study plan to become a software engineer.

Keras is a high-level neural networks library, written in Python and capable of running on top of either TensorFlow or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research.
