Easily Update Ubuntu and Debian Systems with uCareSystem

Easily Update Ubuntu and Debian Systems with uCareSystem

system update

The all-in-one uCareSystem app takes care of many upgrading tasks.

Updates are something that are often ignored for one reason or another. However, if you’re not making a daily (or at least weekly) habit of updating your systems, then you are doing yourself, your servers, and your company a disservice.

Bookmark The Linux Commands For Easier Repeated Invocation

A while ago, we have written about “Keep” utility, which is used to save the Linux commands in Terminal and use them on demand. It is quite useful when it comes to use lengthy Linux commands often. We don’t have to memorize the commands. Just save it using “Keep” utility and use that command on demand. Today, I have stumbled upon yet another similar utility called “Bashpast”. It is used to bookmark the linux commands for easier repeated invocation. This provides an easy way to repeat frequently used commands and saves you few keystrokes. Also, if you have hard time remembering lengthy commands, you can use it to bookmark them. Of course, you can simply do a reverse search using ‘CTRL-R’ to lookup the commands or use aliases, but this utility provides way faster and easier method.

Release of the Mageia 6 Linux distribution with Plasma 5, DNF support, ARM port

After two years of development, it is the genuine pleasure of everyone involved in the Mageia community to announce the release of Mageia 6, the latest milestone of its 100% community-driven GNU/Linux distribution. Mageia 6 is a stable and modern operating system that offers an exceptionally wide range of software, included upwards of 25 desktop environments and window managers, notably Plasma 5 from the KDE project and GNOME. This release sees the addition of the new package manager DNF 2 as alternative to Mageia’s URPMI, which brings support for AppStream-based software centers (e.g. Plasma Discover and GNOME Software), as well as Fedora COPR and openSUSE Build Service (OBS) to complement the already very complete official Mageia repositories. Other major additions for this release are the addition of the ARM architecture, Continue reading “Release of the Mageia 6 Linux distribution with Plasma 5, DNF support, ARM port”

iWant – The Decentralized Peer To Peer File Sharing Commandline Application

iWant – The Decentralized Peer To Peer File Sharing Commandline Application

iWant - Decentralized Peer To Peer File Sharing solution

A while ago, we have written a guide about transfer.sh and that allows you to share files over Internet easily and quickly, and PSiTransfer –  a simple open source self-hosted file sharing solution. Today, we will see yet another file sharing utility called “iWant”. It is a free and open source CLI-based decentralized peer to peer file sharing application.

What’s makes it different from other file sharing applications? You might ask. Well, it’s commandline application. You don’t need any memory consuming GUI utilities. You need only the Terminal. It is decentralized. That means your data will not be stored in any central location. So, there is no central point of failure. iWant allows you to pause the download and you can resume it later when you want. You don’t need to download it from beginning, it just resumes the downloads from where you left off. Any changes made in the files in the shared directory (such as deletion, addition, modification) will be reflected instantly in the network. Just like torrents, iWant downloads the files from multiple peers. If any seeder left the group or failed to respond, it will continue the download from another seeder. It is cross-platform, so, you can use it in GNU/Linux, MS Windows, and Mac OS X.

Check your disk usage with df and du

As system administrator , but also as common user on my PC, one of the more common problem is when a file system got filled up at up at 100% of its size.
So, in this article we’ll see 2 commands that can help us in keeping under control or check the space used in every filesystem and in his directory.

df : report file system disk space usage

du: estimate file space usage
