  • Scrivano is a New App to Take Handwritten Notes on Linux - OMG! Ubuntu!

    If I asked you to name a handwritten note-taking app for Linux chases are you’d namecheck Xournal++. It’s arguably the best one out there as it’s open source, well featured, and a real best-in-class application.

    But there’s always room for more.

    Scrivano is a relatively new hand-written note taking app for Linux (and Windows) that could prove itself handy for anyone looking to jot down hand-written notes, draw simple charts and diagrams, mark-up images, and other similarly nimble tasks.

    The app features four different paper backgrounds: Plain, Lined, Grid, or Dotted. The space between the lines/dots/grid spaces are all configurable too, which is great if you want to get really detailed with sketches and notes.

  • Revocation Reason Codes for TLS Server Certificates - Mozilla Security Blog

    In our continued efforts to improve the security of the web PKI, we are taking a multi-pronged approach to tackling some long-existing problems with revocation of TLS server certificates. In addition to our ongoing CRLite work, we added new requirements to version 2.8 of Mozilla’s Root Store Policy that will enable Firefox to depend on revocation reason codes being used consistently, so they can be relied on when verifying the validity of certificates during TLS connections. We also added a new requirement that CA operators provide their full CRL URLs in the CCADB. This will enable Firefox to pre-load more complete certificate revocation data, eliminating dependency on the infrastructure of CAs during the certificate verification part of establishing TLS connections. The combination of these two new sets of requirements will further enable Firefox to enforce revocation checking of TLS server certificates, which makes TLS connections even more secure.

9 Top Free and Open Source Elixir Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Read more

  • How to Install ClamAV on Arch Linux

    ClamAV is an open-source and free antivirus toolkit that detects many types of malicious software, including viruses, trojans, malware, adware, rootkits, and other malicious threats. One of its primary uses of ClamAV is on mail servers as a server-side email virus scanner or file hosting servers to periodically scan to ensure files are clean, especially if the public can upload to the server. ClamAV supports multiple file formats (documents, executables, or archives), utilizes multi-thread scanner features, and receives updates for its signature database daily to sometimes numerous times per day for the latest protection. The following tutorial will teach you how to configure ClamAV on Arch Linux desktop or server and some basic scan commands using the command line terminal.

  • Linux su vs sudo: what's the difference? | Opensource.com

    Both the su and the sudo commands allow users to perform system administration tasks that are not permitted for non-privileged users—that is, everyone but the root user. Some people prefer the sudo command: For example, Seth Kenlon recently published "5 reasons to use sudo on Linux", in which he extols its many virtues. I, on the other hand, am partial to the su command and prefer it to sudo for most of the system administration work I do. In this article, I compare the two commands and explain why I prefer su over sudo but still use both.

  • How to Change the Default Interface in Linux?

    “Almost everything productive we can do in Linux requires us to have a network connection. Whether developing apps, installing software, scripting, sharing files, or even watching movies, we need a working network connection. Hence, “I require a network connection” is simply an understatement. The only way to enable network connection on a machine is through a network interface. A network interface is a device or a point of connection between a device and a private or public network. In most cases, a network interface is a physical card such as a wireless adapter, a network card, etc. However, this does not necessarily mean that a network interface should be a physical device. For example, a loopback adapter that is not physically visible is implemented by software and available on all devices.” This quick tutorial will show you how to set the default interface in Linux.

  • CoreOS in VirtualBox

    Three Fedora CoreOS (FCOS) update streams are available: stable, testing, and next. In general, you will want to use stable, but it is recommended to run some machines on testing and next and provide feedback. Each stream has a canonical URL representing its current state in JSON format, known as “stream metadata.” For example, the stream metadata URL for stable is: https://builds.coreos.fedoraproject.org/streams/stable.json For automating Fedora CoreOS installations, it is expected that you will interact with stream metadata. While Fedora CoreOS does automatic in-place updates, it is generally a good practice to start provisioning new machines from the latest images.
