#docker Swarm, Kubernetes’s clever little borther
▻https://hackernoon.com/docker-swarm-kubernetess-clever-little-borther-49ac3d0a853?source=rss---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?soLinear 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 (...)

As I explained in my Skonk Works post, I’ve been learning so fast that it’s actually been kind of hard to catch time to digest and write any of it down.For instance, this tutorial series began with teaching you how to install Ubuntu 16.04, but support for Ubuntu 16.04 has just ended and you really should install Ubuntu 18.04, which is what I did after wiping my desktop and turning it into a fulltime personal cloud server! This is good because now I have a completely dedicated Linux machine to run neural network batch jobs on (...)

By way of completely arbitrary example, let’s say it’s a guitar chord finder with an interactive guitar neck and a submission form (like, say, this one).Shameless self-promotion!You’ve made a couple to-do lists, watched a couple tutorials, and you think you’ve got the hang of all this “props” stuff, so you jump right in. It’s going well enough — you’ve got your top level app component, maybe a form, a guitar component… and then, it starts to dawn on you. You’re going to need a guitar… with six strings… with twelve frets each… which all need to communicate information about whether or not they’re muted, pressed, or open…which need to be able to communicate with the form and express a chord… (...)
