Review: LockBox 1.0LockBox is one of the most recent additions to the DistroWatch database. LockBox (sometimes referred to as LBX) is a Linux distribution derived from Ubuntu and elementary OS. It is especially intended for storing and managing cryptocurrencies. It includes several hardened configuration changes for security purposes, a highly restrictive firewall setup, several applications designed for data backups, a password manager, and the Brave Internet browser. LockBox is available for x86_64 machines exclusively and its install media is 3.4GB in size.
In a curious case of life imitating art, the LockBox website currently describes the project using a quote from the DistroWatch information page about the distribution.
One of the first things I discovered about the distribution is LockBox will not boot in Legacy BIOS mode. A boot menu will appear and begin a countdown from five seconds. When the countdown reaches zero, or when we select any of the boot options, the counter simply resets to five seconds again. The boot menu offers to let us "Try or install elementary OS" or "Check disks for defects" and both options simply reset the boot menu counter. When trying to launch the distribution in UEFI mode, only the Try/Install option is presented and choosing it boots the distribution's live environment.
When the live system boots we are shown a graphical window where we can choose our preferred language from a list. We are given the choice to try the live desktop, which loads the Pantheon desktop. Alternatively we can launch the system installer. I'll talk about the Pantheon desktop later in this review.

In this tutorial, we will show you how to install Apache Server on Fedora 35. For those of you who didn’t know, Apache HTTP is a popular web server for Linux servers. It is a free cross-platform web server that is supported on various operating systems. Developers prefer Apache for its speed, security, reliability, robustness, and ease of customization. In addition, Apache is able to meet the needs of many environments as it allows the installation of various extensions and modules.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Apache webserver on a Fedora 35.

Fortunately, over-the-air (OTA) firmware updates are a thing, allowing embedded devices to be reprogrammed over their wireless data connection instead of with a physical hardware device. Security is of course a concern, and thankfully [Refik] explains how to set up a basic framework so that ESP32 OTA updates can happen securely, allowing one to deploy devices and still push OTA updates in confidence.
[Refik] begins by setting up a web server using Ubuntu Linux, and sets up HTTPS using a free SSL certificate from Let’s Encrypt, but a self-signed SSL certificate is also an option. Once that is done, the necessary fundamentals are in place to support deploying OTA updates in a secure manner. A bit more configuration, and the rest is up to the IoT devices themselves. [Refik] explains how to set things up using the esp32FOTA library, but we’ve also seen other ways to make OTA simple to use.

Containers running in Kubernetes Pods are meant to be self-contained compute units that you don’t need to manually interact with. Sometimes you might have to copy files to or from a Pod’s filesystem though, perhaps because you’re debugging a problem and want to archive logs, config files, or caches stored in a container.
Here’s how to move files between your machine and containers in a Pod, using Kubectl’s built-in transfer feature or a manual alternative.

Mozilla Firefox is a free and open-source web browser developed by the Mozilla Foundation. Firefox utilizes the Gecko rendering engine to display web pages, which implements current and future anticipated web formats and standards.
For the most part, Firefox is often up to date with the latest stable release on Linux Mint and Ubuntu-based desktops, however non-stable builds such as beta or the more bleeding edge nightly builds can be installed tested the new features or test your websites before its hits the stable repository.
For the most part, the beta build is what curious users should be installing, and the nightly build should never be used by anyone other than sysadmins or developers looking to test a particular feature.
In the tutorial, you will learn how to add and install the beta and nightly build for Firefox using a PPA maintained by the Mozilla team.

Grafana is a tool for monitoring, analysis, and visualization of real-time system data. From a series of data collected, we will obtain a graphical panorama of the situation of a company or organization. It generates graphs and dashboards from a time-series database (Graphite, InfluxDB, or OpenTSDB). It also allows you to share them as snapshots with other users.

In Linux, using heavy hardware components can be checked and recovered. Specifically, on Ubuntu and Debian systems, finding out the hard-disk bad sectors is easy. Once your hard disk or drive gets some bad sectors or gets corrupted, it gets spread day by day. On Ubuntu and other Debian Linux machines, you can use a few tools or commands to find out the file system errors and repair the errors. Not fixing errors or bad sectors might make your system boot slower and can also affect initialization.

Croc is an open-source CLI-based tool that allows to securely transfer files between systems. During file transfer, a code is generated for the sender and the receiver systems to use for end-to-end encryption. Whether the sender and receiver are on the same network or the different networks, Croc can easily and quickly transfer files between them without the need for port forwarding. Croc can be installed and used on Linux, Windows, and MacOS, allowing you to share files between different operating systems.
In today’s tutorial, we will install Croc to securely transfer files between Ubuntu systems. To install Croc on Ubuntu, you should have root or sudo privileges.
Note: The procedure has been demonstrated on Ubuntu OS. You can use the same installation procedure for Debian OS.

In this article I will show you how to setup SSH login without passwords in a Linux operating system by using key-based authentication.
SSH is used to remotely log into servers for running the commands and programs. However, sometimes you might want or even need to automatically log in to an SSH server without entering your username and password.
The two most popular mechanisms to log into remote systems via SSH are password-based authentication and key-based authentication.
Username and password combination is the most common authentication method for SSH and is a suitable method for most people. But if you regularly use SSH to connect to remote servers, the key-based authentication method is best for you.
So, can you SSH without a password? In short, yes! Here’s how to do it.

A VPC peering connection is a connection between two VPCs that enables you to route traffic between them. We can create a VPC peering connection between our VPCs, or with a VPC in another AWS account. The VPCs can also be in different regions.
We can peer the VPCs across accounts to create a network filesystem and we can also use a VPC peering connection to allow other VPCs to access resources we have in one of our VPCs.

In this tutorial, I am going to take you through the installation of Travis CI on UIbuntu 20.04.
Travis CI is a hosted continuous integration service used to build and test software projects hosted on Github and Bitbucket. Travis CI provided services to Open-source projects for free.
Travis CI enables teams to test and ship apps with confidence. You can easily sync your projects with Travis CI. Travis CI automatically detects when a commit is made and pushed to the GitHub repository that is using Travis CI, and each time this happens, it will try to build the project and run tests.

TL;DR: adding features after the fact is hard, normalizing names is hard, it's patched, carry on.
I promise, the longer version is more interesting and fun to read!
Recently, I was poking around Ansible Galaxy and almost accidentally got access to someone else's namespace. I was actually looking for something completely different, but accidental finds are the best ones!

In the role of a packager, updating packages is a recurring task. For some projects, a packager is involved in upstream maintenance, or well written release notes make it easy to figure out what changed between the releases. This isn’t always the case, for instance with some small project maintained by one or two people somewhere on github, and it can be useful to verify what exactly changed. Diffoscope can help determine the changes between package releases.
Diffoscope is a “smart binary diff” tool that was born in the Reproducible Builds project in Debian, which is also available in Fedora. It “knows” about various types of text and binary formats, and will try to recursively unpack and compare two blobs. In particular it knows that some objects need to be decompressed before comparing, that archives need to be unpacked, and how to deconstruct binary objects like ELF programs and libraries, Java .jar files, Windows .cab files, etc.
