  • How to Execute Curl With Kubectl – Linux Hint

    The command-line tool cURL or Curl, which refers to client URL, is used by developers to transport data to and from a server. At its most basic level, Curl allows you to communicate with a server by defining the destination in the form of a URL and the data you wish to transmit. Curl operates on practically every platform and supports a variety of protocols, which include HTTP and HTTPS. This makes Curl suitable for testing connectivity from a local server to most edge devices or from practically any device. Curl is nearly ubiquitous, whether it’s for validating an API’s output before sending it to production or just requesting a response from a website to ensure it’s not down. Curl is a popular and powerful command. It comes in handy when you are reliant on the command line. It comes with a variety of features and supports a range of protocols. That’s a compelling reason to master this command. Curl commands are intended to be used as a technique to test URL connectivity and a data transmission tool. On the client-side, Curl is driven by libcurl, a free URL transfer library. Because it is developed to function without user interaction, this technology is preferred for automation. Curl can transport several files at once. In the following guide, we are going to check out the usage of the curl command using kubectl in Ubuntu 20.04 operating system.

  • How to Enable ZFS Compression – Linux Hint

    The file system compression feature compresses the files stored on the file system automatically to save the precious disk space of your storage device.
    Like many other file systems, the ZFS file system also supports file system-level compression.

    The benefits of ZFS file system compression are:

    Sleepy Saves Disk Spaces: As I have mentioned, when ZFS compression is enabled, the files you store on your ZFS pool/file system are compressed to save disk space.

    ii) Reduces File Access Time: Processors these days are very fast. They can decompress files in real-time. So, it takes less time to decompress a file than to retrieve it from a storage device (i.e., hard drive). As compressed files take less storage area, they can be retrieved faster from the storage device (i.e., hard drive) than uncompressed files and can be decompressed on the fly. Overall, this reduces file access time and improves the file system performance.

    This article will show you how to enable compression on your ZFS pool and file systems. I will also show you how local and inherited compression of ZFS pool and file systems works. So, let’s get started.

  • Avoid Head Spinning

    If you’re like me and constantly keep triggering it by accident (Blender zooming being Inkscape’s panning having to do with it), you’ll be happy to learn it can be completely disabled.

If you install Windows 11 on an unsupported PC, you will not get updates

You can always install Ubuntu or Linux Mint Being a Linux evangelist it would be very remiss of me not to at least mention it is an option that you have. Linux Distros like Ubuntu and Linux Mint are quite user friendly and easy to set up. It’s a lot easier to install Ubuntu on your laptop or PC than it is to install Windows. You can even install Ubuntu or Linux Mint alongside Windows and choose which OS you want to boot into during startup. I am always telling people that these days it doesn’t really matter which OS you are using as long as you can install Google Chrome. Most of the stuff we do and need is in the cloud. If you are an accountant for example you can use Sage or QuickBooks in the cloud so there is no need for Windows support. You can use Office 365 or Google Workspace and so much more. Your OS just sits behind the scenes unobtrusively facilitating your desires. There was a time when desktop apps ruled the roost and this was a big reason for you not to install Linux but those days are long gone. Ubuntu 20.04 will be supported for the next 10 years so, 2030 inenge ichipo! Ubuntu will also run much faster than Windows 11 will ever will on your old Hardware. You can do that or just keep Windows 10 which Microsoft has said they will keep supporting and updating. Read more
