Recently the OpenSSL 3.0.0 library was released. We decided to look at the project’s code quality and checked it with the PVS-Studio static analyzer. The code quality is excellent. Thus, we cannot write a long article about errors, as we usually do. However, there was one beautiful mistake, and I couldn’t ignore it.

Faire une sauvegarde Windows 10 sur disque dur interne (plus rapide) ou externe ? C’est une question primordiale, combien de fois des systèmes ont été perdus à cause de virus ou de malware, combien de gens vivent avec ces parasites sans pouvoir restaurer leur système ?

En 2020 l’importance de l’informatique, les multiples services que nous utilisons notamment gouvernementaux, rende la nécessité d’avoir un ordinateur fonctionnel incontournable.

Nous allons donc voir comment sécuriser votre système Windows.

A crime has taken place and the detective needs your help. The detective gave you the crime scene report, but you somehow lost it. You vaguely remember that the crime was a ​murder​ that occurred sometime on ​Jan.15, 2018​ and that it took place in ​SQL City​. Start by retrieving the corresponding crime scene report from the police department’s database.

In this #tutorial, we’re going to walk you through the most common mistakes made in each phase of bot building — conception, training, building or connection.Building a bot is a rewarding experience: creating your own artificial intelligence is amazing! However, it can be a challenge, and there are mistakes to avoid. In this piece, we’re going to walk you through the most common or damaging mistakes new bot builders make in each phase of bot building: conception, training, building, connection, user experience and maintenance. Let’s roll!ConceptionBuilding a bot doesn’t start at the first line of code. It starts much earlier, during the conception.During that first step, it’s important to define the use case of your chatbot. What is the problem you want it to solve? What are your business (...)

#docker Swarm, Kubernetes’s clever little borther

Docker Swarm, Kubernetes’s clever little brotherIs kubernetes suitable for any container based project?There is no doubt that kubernetes is one of the most talked about technologies in the domain of #cloud and #containers. Kubernetes provides a complete solution to managing containers, but there are cases where it is not the best solution.The main disadvantage of kubernetes is its complexity and learning curve. This complexity is due to several reasons:We need to know both the “language” of Docker and the “language” of kubernetes.There are a lot of “moving parts” in the infrastructure (kube-apiserver, etcd, kube-scheduler, kube-controller, kubelet, kube-proxy etc..)There are many types of objects (Service, Pod, Deployment, ReplicaSet)A vast amount of features that we do not necessarily need.In (...)

Linear Programming in #python : A Straight Forward #tutorial
▻https://hackernoon.com/linear-programming-in-python-a-straight-forward-tutorial-a0d152618121?so

Linear programming is one of the most common #optimization techniques. It has a wide range of applications and is frequently used in operations research, industrial design, planning, and the list goes on. Alas, it is not as hyped as machine learning is (which is certainly a form of optimization itself), but is the go-to method for problems that can be formulated through decision variables that have linear relationships. This is a fast practical tutorial, I will perhaps cover the Simplex algorithm and the theory in a later post.Problem StatementJust to get an idea, we are going to solve a simple problem regarding production scheduling. Imagine that you work for a company that builds computers. A computer is a fairly complex product, and there are several factories that assemble them (...)

By now, plenty of companies like Pinterest, Uber, Twitter, Trivago, The Washington Post, Starbucks, have already created PWAs to run parallel to their native apps.The reason is obvious, plenty of these companies report very promising numbers, mostly as astonishing as the 97 percent of increase in conversions Trivago has seen.Why should we start developing PWAs now?In (...)
