It can be used as a standalone search engine for the web or as a search engine for e-commerce web applications.

Three years ago, the Heartbleed vulnerability in the OpenSSL cryptographic library sent the software industry and companies around the world into a panic. Software developers didn't know enough about the open source components used in their own products to understand whether their software was vulnerable - and customers using that software didn't know either.

Java, the famous programming language that is useful to us at almost every time in our daily work. Directly or indirectly we work on Java software almost everyday. My fellow developers, coders, programmers also use to develop Java software that is why I decided that it would be worth to write an article on it.

When I first started considering container use in production environments, a question came to mind: When a container may exist across a cluster of servers, how do I get others (people, or applications) to connect to it reliably, no matter where it is in the cluster?

Croteam have put out yet another stable build of The Talos Principle, which brings improvements for the Vulkan version. I did some fresh benchmarks and the different is quite amazing.

Aries’ “M6UL” COM expands on an i.MX6 UltraLite SoC with 4GB eMMC, dual Ethernet ports, and dual CAN ports, as well as DRM ID, encryption, and secure boot. Germany-based Aries Embedded has announced a “M6UL” computer-on-module as a drop-in replacement for its earlier i.MX28-based M28 COM.

The Cloud Native Computing Foundation (CNCF) which itself is a Linux Foundation Collaborative Project, is expanding its roster of supported projects today with the addition of the gRPC project.

The gRPC project is an open source, high performance remote procedure call (RPC) framework originally developed by Google. The gRPC project has already been used outside of Google, with CoreOS and Netflix among the technology's adopters.

Microsoft announced that Skype 5.0 for Linux has entered Beta stages of development after being in Alpha for more than eight months, during which it received numerous builds that users were able to take for a test drive.

There comes a time in your life when you have to share one or more files with someone, whether that someone is a friend, a family member, a colleague or collaborator, or a client. Many people stay true to their open source convictions by doing the job using applications like ownCloud, Nextcloud, or SparkleShare. read more

The guy behind the Linux kernel, Linus Torvalds, has built version 4.10 of the mainline kernel—nicknamed “Fearless Coyote.” Like any new kernel, version 4.10 has a slew of improvements for compatibility with a wide range of hardware. As I was digging through the commit log to see what’s new (a lot, actually), an entry on Kaby Lake caught my eye.

DiRT Rally is one game a lot of Linux gamers have been looking forward to, so here’s my port report and review.

Rainbow Stream allows you to manage just about every aspect of your Twitter account from the command line. Yes, you did read that right. It's a full featured command line Twitter client written in Python. Chances are, you're falling into one of two camps right about now. If you're in the slightly insane one that thinks this is a good idea, stay tuned.

GNU Screen (or just Screen) is a useful and versatile, but somewhat under-appreciated utility that, as part of the GNU project, is included or available in nearly every Linux or UNIX distribution. Screen is a terminal multiplexer, similar to what you would find in a window manager. It is an especially helpful utility if you are restricted to working on a computer or a virtual machine either over an SSH link or through a terminal session on the console. read more

Escape the fogginess and uncertainty of a cloud solution and host your own site at home. A recent convergence of technologies has made this obvious solution both simple and desirable.

In January I wrote several times about my new low-priced ASUS X540S laptop, and how I loaded a variety of Linux distributions on it. I've been using the system for over a month now, and during that time I have come to like it even more than I did initially.

If you think about it, isn't the Internet just a giant mesh network? If we deviate slightly from the standard definition that requires that all nodes to assist in data distribution, the answer is a resounding yes. However, traditional network technologies and the vendor-provided hardware required to run them is often far too expensive to deploy without deep pockets. Open source software aims to solve these problems and enable network connectivity to marginalized groups all around the world. read more

Best alternative for cryptkeeper to encrypt & decrypt folders in Linux.

In this tutorial, I will guide you step-by-step to use docker-compose to create a LEMP Stack environment (LEMP = Linux - Nginx - MySQL - PHP). We will run all components in different docker containers, we set up a Nginx container, PHP container, PHPMyAdmin container, and a MySQL/MariaDB container.
