This article will provide a detailed guide on installing and configuring Apache, Python, and PostgreSQL to run a Django project on MS Windows OS. Django already includes a simplified development server for local code testing, but for production tasks, a more secure and powerful web server is required. We will configure mod_wsgi to interact with […]
Observing the development of the file exchange network is interesting, but participating in it is even more exciting. Nowadays, by setting up and launching a modern NMDC hub, a newly minted administrator gains access to nearly all the developments and accumulated experience in this field from predecessors. They have a system ready for expansion and customization, including through numerous scripts. With ADC hubs […]
Kubernetes has become the standard method, and many will attest to this as they deploy containerized applications at various scales. But while Kubernetes helps us manage messy and complex container deliveries, what helps us manage Kubernetes itself? It can also be complex, convoluted, and hard to manage. As Kubernetes grows and evolves, many of its nuances will certainly be addressed within […]
Turing Pi is a solution for self-hosted applications built on the rack-mount principle found in data centers, only on a compact motherboard. The solution is geared toward building local infrastructure for local application and service development and hosting. Essentially, it's like AWS EC2 but for the edge. We are a small team of developers who decided to create a solution for building bare-metal clusters in the edge […]
Good news for Chromebook users who miss Windows applications on their machines. The beta version of CrossOver has been released, allowing Windows OS applications to run in a software environment on Chromebooks. However, there is a downside to this sweet deal: the software is paid, starting at $40. Nonetheless, it's an interesting solution, and we are already preparing […]
We are pleased to present the beta version of NGINX Service Mesh (NSM), a lightweight service mesh utilizing a data plane based on NGINX Plus for managing container traffic in Kubernetes environments. NSM can be downloaded for free here. We hope you will try it out for dev and test environments — and we look forward to your feedback on GitHub. Implementing microservices methodology is associated […]
Disclaimer: This article does not provide information that is previously unknown to those familiar with the concept of CDN; it serves as an overview of the technology. The first web page appeared in 1990 and was only a few bytes in size. Since then, content has scaled both qualitatively and quantitatively. The development of the IT ecosystem has led to modern web pages being measured in megabytes, and the trend towards […]
