In his HAProxyConf 2019 presentation, William Lallemand (Senior HAProxy Developer) shows how process management in HAProxy has evolved since the beginning of the project; With the advent of systemd, new techniques had to be developed so that users could reload HAProxy safely. The Master-Worker mode simplifies the management of HAProxy processes and introduces interesting features.
Tanay is the Head of Developer Relations at n8n. He has published books on WebVR, virtual assistants on Raspberry Pi, and FirefoxOS. He has been listed in the about:credits of the Firefox web browser for his contributions to the different open source projects of the Mozilla Foundation. I’ve been involved in the DevOps world for a while and yet I finished reading The Phoenix Project only recently. The book piqued my interest in how teams execute their incident response playbooks.
Open-source software started around the millennium and is now one of the cornerstones of modern software development. Open-source projects make their source code available to anyone so that engineers across the world can inspect the code to find bugs or make changes to suit their needs. Today, there are more than 180,000 open-source projects available, according to Wikipedia. We at StackState are big believers in open-source software.
In Ubuntu 20.04 LTS, the OpenSSL 1.1.1f library has been modified to use Security Level 2 by default (previous versions of Ubuntu use Security Level 1). Security Level 2 guarantees that protocols, key exchange mechanisms, cipher suites, signature algorithms, certificates and key sizes provide a minimum of 112 bits of message secrecy. In practice, it means that RSA keys are required to be at least 2048 bits long and ECC keys at least 224 bits using the SHA256 certificate signature algorithm.
Canonical has received FIPS 140-2, Level 1 certification for cryptographic modules in Ubuntu 18.04 LTS, with FIPS-validated OpenSSL-1.1.1. modules included.

Hey there. Welcome to the fifth and final installment in our series on successfully deploying an app to AWS with the least effort. This week, we'll discuss things you need to worry about now that you've released, plus optimizing your app. Ok, so you've released your app. Congrats! However, we both know your work doesn't end here. You should continue improving your app, both on the end-user side and the back end.
Today we launched the Rancher Academy, our new free training portal. The first course is Certified Rancher Operator: Level 1, and in it you’ll learn exactly how to deploy Rancher and use it to deploy and manage Kubernetes clusters. This professional certification program is designed to help Kubernetes practitioners demonstrate their knowledge and competence with Kubernetes and Rancher – and to advance in their careers.
For teams that deal with machine learning (ML), there comes a point in time where training a model on a single machine becomes untenable. This is often followed by the sudden realization that there is more to machine learning than simply model training. There are a myriad of activities that have to happen before, during and after model training. This is especially true for teams that want to productionize their ML models.
