Microsoft’s New Linux Distro Is a Warning Shot at Red Hat

A Linux Tux-like Logo with a Windows logo on his bellyhendrickn/Shutterstock / Microsoft

Ever so quietly, Microsoft dropped a new operating system out in the wild. No, not Windows 11. Microsoft created its own Linux Distribution. And while you might be tempted to crack jokes that Microsoft hates Linux, this is a big deal. Especially for anyone who relies on Red Hat or Suse.

Microsoft’s new Linux Distro, dubbed Common Base Linux (CBL)-Mariner, isn’t the type of distro you’d want to install directly on any old machine. It’s primarily meant for cloud infrastructure and edge products. Specifically Microsoft’s Cloud and Edge products.

But if you are curious, it’s possible to run. Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide to ISO CBL-Mariner image. With that, you can easily get it up and running. And you can build CBL-Mariner on an Ubuntu 18.04 desktop. So you can try it out, but that’s not the real purpose here.

It’s not a guarantee yet, but with CBL-Mariner, Microsoft could bring what it does best in Windows to Linux—Patch management and distribution. Windows updates might be a hated affair in the consumer world, but in the enterprise area, Microsoft wins points for predictability and reliability. You can carefully install updates, see what they do, roll them out to many machines at scale as you see fit. While Red Hat and Suse provide well-respected distros and some support, they don’t go anywhere near as far as Microsoft. And few other Linux companies (if any) can claim to support on the same massive scale as Microsoft.

It’s a compelling argument for anyone managing servers, especially lots of servers. The biggest reason to go with Windows server management tool is the superior server management processors, but Windows presents its own problems. Linux bypasses many of those issues but lacks the same patching capabilities. But with CBL-Mariner, you can have the best of both worlds. World-class server management capabilities with strong provisioning support for both Unix and Windows and the ability to skip Windows if you need.

It’s hard to overstate the complexities in patching Unix servers compared to the Windows equivalent; it’s a job often done by multiple people on the former end and sometimes handled by just one on the latter. And most people wouldn’t notice as Microsoft quietly became one of the largest Linux distributors in the world. The hard part will be winning over the community. But recent decisions, like letting GitHub live on its own without much control, may help.

It’s too early to say that Microsoft will definitely go in this direction yet, but it’s making all the right moves to enter the Linux Enterprise space. And possibly own it. Companies like Red Hat should probably take notice.

How to Recursively Change File Permissions in Linux

linux-file-permissions-featured.jpg Because Linux is a multi-user operating system, it has a mechanism that sets and manages file permissions to ensure that only authorized processes and users can access various directories and files.

The 7 Best Audacity Alternatives

Apple Logic Pro and Ocenaudio screenshots in a collage with Audacity logoOcenaudio, Apple, Audacity

Audacity is the go-to audio editor for a lot of people, and for good reason—it’s simple, free, and still reasonably powerful. But with the recent privacy controversy weakening confidence in the new owners, now’s a good time to look at the alternatives. Fortunately, there are a lot of great ones that have been competing with Audacity for years.

But first off, let’s talk about what won’t be included in this list: Audactiy forks. Audacity is open-source, meaning its source code is public and modifiable, directly opening the doors for forks. A fork is a piece of software built off of the source code of an open-source program. Usually, these still share a lot of similarities with the original program but introduce a lot of new stuff.

The reason they won’t be covered here, though, is because they’re often-time not as reliable as dedicated pieces of software. Forks are commonly owned and maintained by community members of the original program, and because of that, can go for long periods of time without updates. Taking a look at one of the most promising Audacity forks, Tenacity, you’ll see that the project maintainer recently had to step down, which is sure to slow development for a while. Uncertainty like this plagues most forks, which is why they won’t be covered here.

What to Look for in an Audacity Alternative

Chances are, if you’re reading this, Audacity is your main tool for anything audio-related, which can make it a tough thing to replace. But there are a lot of great DAW’s (Digital Audio Workstation) out there, so here are the things we looked for when considering entries for this list.

  • Features: While Audacity is used across the industry, the ways it’s used varies a lot. From podcast recording to music creation, people have found plenty of ways to push Audacity’s relatively limited features to the max. Because of that, we sought out a variety of software today, ranging from straightforward and easy-to-learn audio editors to industry-standard workstations. While the basics like recording audio, multi-track support, splicing and rearranging clips, and applying effects are seen in every program here, some go much further. If you’ve been reaching the limits of Audacity, then we have some fantastic audio-editing powerhouses here that will expand the scope of your work.
  • Open-Source: This means a program’s source code is public and easily modifiable by anyone with the know-how. While this may not sound like much to an average user, being open-source makes it much easier for people to create third-party add-ons to a program that can add new features. As we talked about earlier, Audacity is open-source, but there aren’t many other options out there that share this characteristic. We’ve only included one in this article, Ardour, so if that’s a big priority for you, you know where to look first.
  • Price: Being free is a major selling point for Audacity, so naturally, you’re likely looking for something free to replace it as well. Fortunately, there are multiple quality editors available for free we’ll be covering today. Still, we also included a few paid-for programs if you want to dive into some of the more professional options.
  • Platforms: Audacity is available on Windows, macOS, and Linux, so to make sure we don’t leave anyone out, most of the programs here support all three platforms as well. The only exceptions to this are Adobe Audition which is only available on macOS and Windows, and Apple’s software exclusive to macOS.

Easy to Use: Ocenaudio (Windows/macOS/Linux)

Ocenaudio main editing pageOcenaudio

While some people use Audacity for all of their audio editing, many use it rather sparingly for simple audio projects. If you aren’t making music or fine-tuning your voice to that perfect pitch, you probably just need something to record your audio with and then do some simple editing. So if that describes your time with Audacity, then Ocenaudio is what you’ll want to jump to—it focuses on simplicity and ease of use above all else. While the UI appears dated, it’s extremely easy to navigate, which means your transition period from Audacity to Ocenaudio shouldn’t last too long.

But while simplicity is the focus, that doesn’t mean Ocenaudio lacks features. You can still apply effects, fine-tune the EQ and gain (with a real-time preview, so you know what the audio will sound like before actually making any changes), and use the multi-track design for mixing. There are definitely limits relative to more advanced editors, but if you rarely dive into Audacity’s more complex tools, you’re unlikely to notice the limits here.

Ocenaudio is also completely free, so there’s no risk in trying it out.

Easy to Use


Ocenaudio’s straightforward and easy to learn design will make the transition period a breeze.

For Mac Users: GarageBand (macOS)

GarageBand main instrument editing pageApple

When it comes to Apple hardware, Apple’s software tends to be the best match, and GarageBand is a great example. While primarily made for entry-level music production, it also works for editing podcasts and voiceovers as well. You can mix up to 255 audio tracks at once, record music from digital instruments, and fine-tune it all using GarageBand’s straightforward UI. It can even be used to learn instruments, with entire lessons designed to help you play the piano and guitar.

While there is certainly a focus on music production, the standard editing tools and effects are also here, so GarageBand remains a fairly versatile program. It’s a great option if you’re using Apple devices but still want something free.

For Mac Users


Apple’s entry-level audio editor with a large focus on music production.

Open-Source: Ardour (Windows/macOS/Linux)

Main Ardour editing pageArdour

Ardour is the only program here that’s open-source, meaning it’s free and easy to modify—but it’s still packed with features for all sorts of audio editing. There’s an unlimited number of tracks, dozens of supported file formats, and extremely in-depth effects and mixing tools to get that perfect sound. Ardour prides itself on adding features its users want and need, creating an excellent DAW whether you’re dealing with voiceovers, vocals, or instruments.

This is further into the professional scene than what’s been covered so far, so it will be intimidating if you’re not experienced with a full DAW. There are lots of buttons, dials, and sliders to mess around with, but you can solely focus on the simpler tools if those fit the bill for what you’re doing. Whether you push it to its limits or not, Ardour is a real powerhouse in this scene.



If you’re missing the open-source nature of Audacity in particular, Ardour is the best replacement.

The Full Package: DaVinci Resolve 17 (Windows/macOS/Linux)

DaVinci Resolve 17 Fairlight editing pageBlackmagic Design

To start, let’s make something clear: DaVinci Resolve is a video editing program first and foremost—and a really great one at that. However, DaVinci Resolve prides itself on including everything you need to create a video, including standard video editing, color grading, special effects, and, notably right now, audio editing. There is an entire DAW hiding within Resolve called Fairlight, and on top of some solid features, it has a clean and straightforward UI.

There are special audio effects, you can quickly edit the EQ and gain, there are plenty of tools for cleaning up the sound, and you can use over 700 tracks at once. While these tools are designed with video production in mind, you can use Resolve solely for audio editing—and if you are working with video as well, then being able to jump from video to audio editing quickly is extremely useful.

DaVinci Resolve 17 is completely free, which is an amazing deal considering the functionality it provides. Whether you want a DAW with a clean design or you’re a video editor with advanced audio needs, Resolve has you covered.

Powerful and Affordable: Reaper (Windows/macOS/Linux)

Reaper main audio editing pageReaper

This is the first paid program we’ll be talking about, but Reaper still keeps things reasonably affordable, especially considering how much it brings to the table. Reaper is a complete audio production tool for music, vocals, voiceovers, and other audio-related projects. It’s built to be as fast and efficient as possible, both in performance and UI design, with plenty of effects to alter your recordings. There’s support for 200+ tracks, digital instruments and physical audio hardware, and free updates constantly improve the program after purchase. You can also use third-party plugins to further personalize the program to your liking—both aesthetically and functionally.

Without a doubt, Reaper is the best solution to professional audio editing without professional prices. It has the tools to rival the larger names in this field without breaking your budget. As long as you’re not making over $20,000 a year from creations using Reaper, you only need the “Discounted” license. For a one-time price of $60, this grants access to everything Reaper has to offer (if you use Reaper in a professional capacity and make more than that, then you’ll need the commercial license for $225). There’s also a 60-day free trial if you want to give it a spin before paying.

Professional Grade: Adobe Audition (Windows/macOS)

Adobe Audition main editing pageAdobe

Audition is an industry-level workstation that you should look at if you already use the Creative Cloud. Not only does it offer all the tuning tools you’d need out of a DAW (along with a wide range of effects and free sound samples), but it also works in tandem with other Adobe products such as Premiere Pro and After Effects. Considering the limited audio editing tools found in both video programs, this is a crucial feature for advanced users.

But that’s not to say Audition can’t stand on its own two legs; it definitely can; It features a multi-track design with no limits, in-depth composition and analysis tools, and multiple forms of noise reduction for dealing with white noise and hissing. Like most of the other options here, Audition is built to be a one-stop-shop for everything audio, and it does a great job at that.

Like the rest of Adobe’s products, Audition runs on a subscription service—either $20.99 a month for Audition by itself or $52.99 a month for the entire Creative Cloud.

Apple’s Full Offering: Logic Pro (macOS)

Apple Logic Pro main editing pageApple

Logic Pro is Apple’s proper DAW. It certainly doesn’t disappoint with a straightforward but powerful UI and excellent performance on Mac devices (especially those with the newer M1 chips ). Creating music, recording a podcast, and fine-tuning your recordings is made as simple as possible, without compromising on the options you need.

You can still fine-tune your audio to your heart’s content, create music with digital instruments, apply effects, and make use of up to 1,000 audio tracks (which might as well be unlimited). Logic Pro is full of little UI touches that pull the whole program together and makes it a pleasure to work with whether you’re doing it professionally or as a hobby.

Regardless of why you use it, Logic Pro will cost a decent amount. There’s a 90-day free trial to take advantage of, which is always great to see, but afterward, it will cost you $199.99 for a full license.

How to Use the Chown Command in Linux to Change File Ownership

chown-command-linux-featured.jpg On Linux systems, each file is associated with an owner and group owner. When you don’t have the appropriate permission, you won’t be able to access or edit the files or directory. On a Linux system, there is a “change owner” (chown) tool that allows you to change the owner of a file/directory as well as the group owner. Let’s see how you can use the chown command in Linux to better manage your files and folders.

Windows 11 is much more than a new theme slapped onto Windows 10

The latest Windows focuses heavily on improved task management, prettier UI, and a much more ambitious Microsoft Store.

Enlarge / The latest Windows focuses heavily on improved task management, prettier UI, and a much more ambitious Microsoft Store. (credit: Microsoft)

Earlier this morning, we got our first official look at Windows 11 by way of Microsoft’s What’s New For Windows event. The new OS offers several significant, functional changes to what we’ve become accustomed to in Windows 10—this isn’t just the same old operating system with a fresh coat of paint.

However, Windows 11 absolutely does get that fresh coat of paint. Its new desktop environment makes heavy use of translucent window dressing with rounded corners, an effect which brings to mind panes of frosted glass. In many ways, the new look is reminiscent of compiz-based Linux desktop environments circa 2010—but with significantly higher resolution and a more coherent overall theme.

Microsoft Chief Product Officer Panos Panay ties the new look to eyebrow-raising statements about emotion: “We understand the responsibility of [functionality and practicality] more than ever before, but it must also be personal—and maybe most importantly, it must feel emotional.”
