VPC (Virtual Private Cloud) falls under - Network and Content Delivery - service in AWS (Amazon Web Services). VPC provides us logically a virtual private, isolated cloud. In this article, we will see how to create a VPC using the Wizard as this is the simplest way to start with.

I've written before about what a community manager does, and if you ask ten community managers, you'll get 12 different answers. Mostly, though, you do what the community needs for you to do at any given moment. And a lot of it can be repetitive. Back when I was a sysadmin, I had a rule: if I had to do something three times, I'd try to automate it. And, of course, these days, with awesome tools like Ansible, there's a whole science to that. read more

Meld is one of my essential tools for working with code and data files. It's a graphical diff tool, so if you've ever used the diff command and struggled to make sense of the output, Meld is here to help. Here is a brilliant description from the project's website: read more

‘The world around us may be going through strange times, but so far kernel development looks normal’ says Penguin emperor. Linus Torvalds has released a new release candidate of the Linux kernel – version 5.6 rc7 - and added a little COVID-19 commentary.…

The Raspberry Pi makes for a useful and inexpensive home server for lots of things. I most often use the Raspberry Pi as a print server to share a laser printer with other devices in our home or as a personal file server to store copies of projects and other data.

Cockpit is a very useful utility allowing you to manage a compatible system over the network from the comfort of a web browser (See the list of supported web browsers and Linux distributions).

Recently, we published an article about why developers prefer to code at night. Author Matt Shealy highlighted the many benefits of nocturnal programming including the quiet time and space for creative thinking.

Community building is table stakes in the success of any open source project. Even outside of open source, community is considered a competitive advantage for businesses in many industries—from retail, to gaming, to fitness. (For a deeper dive, see "When community becomes your competitive advantage" in the Harvard Business Review.)

Everyone knows they shouldn't take shortcuts, especially in their work, and yet everyone does. Sometimes it doesn't matter, but when it comes to code development, though, it definitely does. As any experienced programmer knows, building your code the quick and dirty way soon leads to problems down the line. These issues might not be disastrous, but they incur a small penalty every time you want to develop your code further.

With ventilators in dangerously short supply during the COVID-19 pandemic, a number of DIY groups have begun working on open source designs that could be made at home.

Examining files from the command-line is generally an easy thing to do. You just run the command you want, followed by a list of files to be examined. Dealing with binary files, however, is more complicated. These files are often packaged up into archives, tarballs, or other packaging formats. The run-on-binaries script provides a convenient way to run a command on a collection of files, regardless of how they are packaged. The invocation of the script is quite simple: read more

We not only don't know how many people have coronavirus in the US, but we also don't even know how many have been tested. So, researchers, using open-source tools, are digging out the real numbers for us.

Scary idea, but can work if IT bods are there to hold their hands. It has been the subject of hype and overblown expectations, but that is not set to dampen investment in robotic process automation – the idea that simple software “robot” can carry out annoying admin tasks. But as organisations begin to understand how best to exploit RPA, IT departments will be finding a new role.…

SUSE, the Linux and cloud company, and Cloud Foundry are releasing KubeCF. It will enable you to run the Cloud Foundry PaaS on Kubernetes.

Social networks have revolutionized people's lives in the last several years. People use social channels every day to stay connected with friends and family. But a common question remains regarding privacy and data security. Even if social networks have created complex privacy policies to protect users, maintaining your data in your own server is always the best option if you don't want to make them available to the public. read more

Samba is a free and open-source software that can be used to share files, folders, and printers between Linux and Windows systems. In this tutorial, we will learn how to install Samba and configure it as a standalone sharing server on CentOS 8.

Arbor unveiled three Rockchip -ased computers that run Android 9.0. The “AAES-RK391” is an RK3399-based mini-PC for signage with dual HDMI ports, and the 10.1-inch RP-101K open frame panel PC and similar RP-101P Android Price Checker tap the PX30.

A network firewall is more or less what it sounds like: a protective barrier that prevents unwanted network transmissions. They are most frequently used to prevent outsiders from contacting or using network services on a system. For instance, if you’re running a laptop at school or in a coffee shop, you probably don’t want strangers […]

If there's one word people use to describe Git, it's "powerful." Nobody can deny that Git is indeed a powerful beast, but after months of struggling to do embarrassingly basic things in it, I realized that mere mortals like me were never going to wield that power through a command-line interface.
