  • The 10 Important Linux Jargon Busters | FOSS Linux

    What better way to filter through the Linux World than through a Linux jargon buster? The Linux system has, for some time, been the UFO of the Operating Systems universe. Not long ago, the public pronunciation of the word Linux would have mirrored concerning glares from OS users who were yet to understand it. However, as with all the UFO protocols, the most daring step is making the first contact.

    The first contact between the curious OS users and the Linux system turned out to be a blessing in disguise or, as the cool kids say, a match made in heaven. It was a perfect friendship. However, for a friendship to last, there must be a means of communication. The SI unit of communication is language. The language of communication between Linux and most of its curious supporters was not blissful initially and turned out to be jargon. However, it never implied that Linux is unteachable.

    To navigate the Linux world comfortably, you only need to master and understand a few key terms. Afterward, you will be ready to certify yourself out of the Linux beginner’s class. This article has the Linux jargon busters as the main guests. Let us give this Linux jargon the stage to introduce themselves before the jargon busters take center stage. We should understand this sort-after Linux jargon in a way that relates to their contribution to the Linux OS.

  • How To Install Bitcoin Core Wallet on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install the Bitcoin Core Wallet on Ubuntu 20.04 LTS. For those of you who didn’t know, Bitcoin Core is programmed to decide which block chain contains valid transactions. The users of Bitcoin Core only accept transactions for that blockchain, making it the Bitcoin block chain that everyone else wants to use. It is these users who keep Bitcoin decentralized. They individually run their own Bitcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which blockchain is valid.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Bitcoin Core Wallet on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

  • How to compare video files on Linux with Identity

    Identity is an exciting program for Linux that allows Linux users to take two video clips and compare and contrast them. If you’re a video editor that uses Linux, this could be a useful program. Here’s how to use it.

    [...]

    Identity is a handy tool, but it does not come pre-installed on any Linux operating systems (that we know of). For this reason, we must demonstrate how to set up the Identity app on Linux before continuing with this guide.

    There are three ways to get the Identity app set up on your computer. The first (and arguably best) way is Flatpak. However, if you do not like the Flatpak app store, you can install it through the Arch Linux AUR or even the source code.

    To start the installation of Identity on your Linux PC, launch a terminal window on the desktop. Once the terminal window is open and ready to use, follow along with the installation instructions outlined below that corresponds with the instructions, you prefer.

  • How to Enable KVM Virtualization on Raspberry Pi 4 – Linux Hint

    The full form of KVM is Kernel Virtual Machine. It is the virtualization solution for Linux. KVM is a Linux kernel module that allows the Linux kernel to act as a hypervisor program like VMware ESXi or VSphere.

    Up until now, you could not run KVM virtualization on Raspberry Pi devices. One of the main reasons for this was that the Raspberry Pi 3 and older versions have only 1 GB of memory. 1 GB of memory is insufficient for KVM virtualization. Docker is a better solution for these devices.

    The recently released Raspberry Pi 4 8 GB model made KVM virtualization possible on the Raspberry Pi. Linux distributions like Fedora, Manjaro, etc., made KVM virtualization easy for the Raspberry Pi 4 by precompiling the KVM Linux kernel module. Our all favorite Raspberry Pi OS may follow this path someday as well.

    In this article, I am going to show you how to install KVM on Raspberry Pi 4 and create a KVM virtual machine on the Raspberry Pi 4. So, let’s get started.

  • Safari isn't protecting the web, it's killing it

    There's been a lot of discussion recently about how "Safari is the new IE" (1, 2, 3, 4, 5).

    I don't want to rehash the basics of that, but I have seen some interesting rebuttals, most commonly: Safari is actually protecting the web, by resisting adding unnecessary and experimental features that create security/privacy/bloat problems.

    That is worth further discussion, because it's widespread, and wrong.

    More specifically, Safari's approach isn't protecting the web from bloat & evil Google influence, because: [...]

  • Hasta la Vista Gmail

    I’ve been a Gmail user pretty much since day 1, when it was still an invite-only service in 2004.1 Not anymore. Over the past month I’ve migrated most of my email to Fastmail and I’m extremely happy with the result.

    Why bother? Well, I guess it won’t come to you as a shock that I’ve felt progressively more uncomfortable with how Google (and the like) are handling my personal data. I’ve also been getting quite frustrated with attempts to make email/my inbox “smarter”. I never needed a “priority inbox”, auto-categorization of email, etc. Simple is good. Just put the newest emails on the top and I’ll sort it out from there.

We have created Easy Secure Photos (ESP) to enable users to protect their photos on cloud photo services such as Google Photos. [...]

  • Joint Open Letter: States Must Implement Moratorium on Surveillance Technology - PEN America

    We the undersigned civil society organizations and independent experts are alarmed at the media revelations that NSO Group’s spyware has been used to facilitate human rights violations around the world on a massive scale. These revelations are a result of the Pegasus Project and are based on the leak of 50,000 phone numbers of potential surveillance targets. The project is a collaboration of more than 80 journalists from 16 media organizations in 10 countries coordinated by Forbidden Stories, a Paris-based media non-profit, with the technical support of Amnesty International, who conducted forensic tests on mobile phones to identify traces of the Pegasus spyware.

  • Canonicalization Attacks Against MACs and Signatures

    Canonicalization Attacks occur when a protocol that feeds data into a hash function used in a Message Authentication Code (MAC) or Digital Signature calculation fails to ensure some property that’s expected of the overall protocol.

    The textbook example of a canonicalization attack is the length-extension attack against hash functions such as MD5–which famously broke the security of Flickr’s API signatures.

    But there’s a more interesting attack to think about, which affects the design of security token/envelope formats (PASETO, DSSE, etc.) and comes up often when folks try to extend basic notions of authenticated encryption (AE) to include additional authenticated (but unencrypted) data (thus yielding an AEAD mode).
