Btrfs, which stands for "Butter FS" or "B-tree FS," is a modern Linux file system. It was developed to overcome the limitations of older file systems like ext4 or ext3. Btrfs is an excellent choice for efficient storage management on multiple Hard Disk Drivers. It supports Linux file systems with snapshots, subvolumes, and built-in RAID-like capabilities that provide robust data protection. It is designed to handle huge file systems and file sizes. Btrfs incorporates checksumming and COW (Copy-on-write), making it more resilient to data corruption. The COW feature means changes are written to new locations instead of overwriting existing data, enhancing data protection and enabling snapshots. After installation, let us see how to install Btrfs support for Debian Linux 11 or 12 using the CLI. Why am I using BTRFS on an existing Debian Linux system? In my case, the EC2 VM AMI is configured to use ext4 by default at AWS. However, I had to make changes since I needed to store files using EBS (Elastic Block Store) and Python code expected to see BTRFS. Hence, this quick tutorial.

GnuPG2 (or GPG2) is an open-source and free tool that implements the OpenPGP standard. Its primary purpose is to encrypt your sensitive information to protect it from unauthorized access. It also allows you to create digital signatures, guaranteeing that the data hasn't been tampered with while in transit. Many newly created Debian 11/12 cloud VMs and images may not have the gpg/gpg2 command installed. Thus, you will get an error that reads "-bash: gpg: command not found." Here is how to fix this error and install gnupg2 on a Debian Linux 11 or 12. Further, you will learn how to use the gpg command.

Sometimes, when you try to install specific Debian Linux packages, you might encounter an error message that reads: Unable to locate package pkg-name-here In many cases, the required package might already be present in the remote download repos. It would be best to have an additional repository, such as contrib, which adds extra packages to the core Debian Linux system. To enable and use the contrib repository in Debian Linux version 10/11/12 or newer versions, follow the instructions below.

The Uncomplicated Firewall (UFW) needs to be configured to allow traffic on UDP ports 67 and 68, regardless of whether the Dynamic Host Configuration Protocol (DHCP) server is local or remote. Additionally, it may be necessary to open both TCP and UDP port 53, which are used for Domain Name Service (DNS). In small business and home environments, typically, both DNS and DHCP services come from a single device. Hence, it would be best if you opened both DHCP and DNS ports using the ufw command.

I recently had to submit multiple PDF files for government work, but the web form only allowed for the uploading of a single file. This meant that I had to merge the PDF files into one on Linux. To do this, I used a command-line tool called pdfunite, which is a Portable Document Format (PDF) page merger. Let us see how to install and use the pdfunite in Linux.

Microsoft has released a public preview of its redesigned Windows Recall feature, five months after withdrawing the original version due to security concerns. The feature will initially be available only on Qualcomm Snapdragon X Elite and Plus Copilot+ PCs running Windows Insider Dev channel build 26120.2415. Recall, which continuously captures and indexes screenshots and text for later search, now includes mandatory encryption, opt-in activation, and Windows Hello authentication. The feature requires Secure Boot, BitLocker encryption, and attempts to automatically mask sensitive data like passwords and credit card numbers. The feature is exclusive to Copilot+ PCs equipped with neural processing units for local AI processing.

An anonymous reader shares a report: Plex is beginning to test its "newly reimagined Plex experience," which will be available first on mobile and is coming to TV platforms "very soon." Plex says the new experience has been in development for almost two years and is "designed to bring everything you love into one seamless interface." But don't worry -- while the new version of the app is currently missing some features, Plex says it will be "closing those gaps" and will keep the current app available during the preview, which will hopefully prevent a Sonos-like debacle. A big change for the new app is redesigned navigation that more clearly delineates between media you might have on your Plex server and the company's streaming and on-demand offerings. The bottom bar has dedicated tabs for your media libraries, live TV, and on-demand movies and shows. The Watchlist, which lets you make a list of things you want to watch, has a spot at the top of the app. And artwork is shown more prominently.

Damage to two undersea fiber-optic cables in the Baltic Sea this month points to growing vulnerability of critical submarine infrastructure, with German officials suspecting sabotage and Swedish police investigating a Chinese cargo vessel's involvement. The incident highlights escalating risks to the global submarine cable network, which carries 99% of international telecommunications traffic through 530 cable systems spanning 850,000 miles. These garden hose-thick cables facilitate trillions in daily financial transactions and vital government communications. Security experts warn that Russia has increased monitoring of undersea cables amid tensions over Ukraine. Taiwan reported 36 cable damages by foreign vessels since 2019, while Houthi rebels denied targeting Red Sea cables this year. Though most of the 100-plus annual cable faults are accidental, deliberate sabotage remains a concern. Repairs are costly, with new transatlantic cables running up to $250 million.
