Amazon and United Launch Alliance will launch 27 full-scale satellites on April 9 as part of Amazon's Project Kuiper, marking the company's first major step toward building a global satellite internet network to rival SpaceX's Starlink. GeekWire reports: ULA said the three-hour window for the Atlas V rocket's liftoff from Cape Canaveral Space Force Station's Space Launch Complex 41 in Florida is scheduled to open at noon ET (9 a.m. PT) that day. ULA is planning a live stream of launch coverage via its website starting about 20 minutes ahead of liftoff. Amazon said next week's mission -- known as Kuiper-1 or KA-1 (for Kuiper Atlas 1) -- will put 27 Kuiper satellites into orbit at an altitude of 280 miles (450 kilometers). ULA launched two prototype Kuiper satellites into orbit for testing in October 2023, but KA-1 will mark Amazon's first full-scale launch of a batch of operational satellites designed to bring high-speed internet access to millions of people around the world. [...] According to Amazon, the Kuiper satellite design has gone through significant upgrades since the prototypes were launched in 2023. Amazon's primary manufacturing facility is in Kirkland, Wash., with some of the components produced at Project Kuiper's headquarters in nearby Redmond. The mission profile for KA-1 calls for deploying the satellites safely in orbit and establishing ground-to-space contact. The satellites would then use their electric propulsion systems to settle into their assigned orbits at an altitude of 392 miles (630 kilometers), under the management of Project Kuiper's mission operations team in Redmond. Under the current terms of its license from the Federal Communications Commission, Amazon is due to launch 3,232 Kuiper satellites by 2029, with half of those satellites going into orbit by mid-2026.

In a move that has sparked significant discussion within the Ubuntu Linux fan-base and community, Canonical, the company behind Ubuntu, has announced its intention to explore the potential replacement of GNU Core Utilities with the Rust-based "uutils" project. They plan to introduce new changes in Ubuntu Linux 25.10, eventually changing it to Ubuntu version 26.04 LTS release in 2026 as Ubuntu is testing Rust 'uutils' to overhaul its core utilities potentially.

Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks. Some industries where KSH is still commonly used include finance and telecommunications. While Bash has become the dominant shell in many Linux distributions, KSH still holds a significant presence in Unix-like environments, particularly in legacy systems. Therefore, installing KSH and practicing with it is worthwhile if you plan to work in such environments.

Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in this tutorial, we will start with the sed command syntax and examples.

Keeping your FreeBSD server or workstation updated is crucial for security and stability.

Rsync is a opensource command-line tool in Linux, macOS, *BSD and Unix-like systems that synchronizes files and directories. It is a popular tool for sending or receiving files, making backups, or setting up mirrors. It minimizes data copied by transferring only the changed parts of files, making it faster and more bandwidth-efficient than traditional copying methods provided by tools like sftp or ftp-ssl. Rsync versions 3.3.0 and below has been found with SIX serious vulnerabilities. Attackers could exploit these to leak your data, corrupt your files, or even take over your system. There is a heap-based buffer overflow with a CVSS score of 9.8 that needs to be addressed on both the client and server sides of rsync package. Apart from that info leak via uninitialized stack contents defeats ASLR protection and rsync server can make client write files outside of destination directory using symbolic links.

Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotchas occur.

After years of development and testing, the ZFS raidz expansion is finally here and has been released as part of version 2.3.0. ZFS is a popular file system for Linux and FreeBSD. RAIDz is like RAID 5, which you find with hardware or Linux software raid devices. It protects your data by spreading it across multiple hard disks along with parity information. A raidz device can have single, double, or triple parity to sustain one, two, or three hard disk failures, respectively, without losing any data. Hence, expanding or adding a new HDD is a very handy feature for sysadmins in today's data-sensitive apps.

Incus and Docker both use Linux kernel features to containerize your applications. Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside when they are stopped. Because of the Linux kernel support nesting feature, you can run Docker inside Incus. This page explains how to run Docker inside Incus containers.

The KVM-ok command command will tell you if your Debian or Ubuntu Linux-powered server can host hardware-accelerated KVM virtual machines. KVM (Kernel-based Virtual Machine) is a free and open-source virtualization technology that is used with every Linux kernel. In other words, KVM will make your Linux computer into a hypervisor, allowing you to run multiple isolated virtual machines (VMs) on a single physical machine. However, KVM depends upon CPU hardware virtualization extensions like Intel VT-x or AMD-V to provide high-performance virtual machines. This support must be enabled in the BIOS. Apart from that, some cloud service providers also allow nested virtualization that will help you to run VMs inside your instances. However, this may not be enabled in BIOS or instance configuration. Thus, you need to install the kvm-ok command to determine whether such support exists.

Linux and Unix like operating systems comes with z* commands. These commands allow you to read gzip compressed text files using zless, zcat, zmore, and friends commands. The gzip command reduces the size of the files using Lempel-Ziv coding (LZ77). Whenever possible, each file is replaced by one with the extension .gz while keeping the same ownership modes, access, and modification times. z* commands have some cool usage too, such as display the current time in different zonename.
