GNOME: Shell Extension, Calculator and GStreamer

GNOME
  • Dash To Panel v24 Released With Vertical Panel Orientation, Update From GitHub Feature

    Dash to Panel, an icon taskbar for Gnome Shell, was updated to version 24, bringing support for vertical panel orientation (left or right of monitor), the ability to update the extension directly from the GitHub releases, and more.

    The Gnome Shell Dash to Panel extension combines the Dash with the top panel into a single dock. This way you have running applications (and favorite/pinned applications), the tray, the system menu, and date / time indicator on a single panel.

    Don't confuse Dash to Panel with the somewhat similar Dash to Dock extension (from which the Ubuntu Dock was forked from).

  • GNOME Calculator and GTK’s Entry

    Recently GNOME Calculator has gained a library for math expression parsing and calculation, as a parallel effort to the one used internally for the application, called GCalc.

    While GCalc allows to take a string to create an object oriented representation of it and can perform multi-precision calculations, this feature was unable to be used outside, just VDA is using it for math expression parsing, but no-more, yet.

    In order to expose GCalc features to user oriented applications, now a new library called GCi was added. GCi provides, for now, a controller for GTK Entries.

  • VCR to WebM with GStreamer and hardware encoding

    My family had bought many years ago a Panasonic VHS video camera and we had recorded quite a lot of things, holidays, some local shows, etc. I even got paid 5000 pesetas (30€ more than 20 years ago) a couple of times to record weddings in a amateur way. Since my father passed less than a year ago I have wanted to convert those VHS tapes into something that can survive better technologically speaking.

    For the job I bought a USB 2.0 dongle and connected it to a VHS VCR through a SCART to RCA cable.

Dash to Panel 24 Released with Vertical Option

  • Dash to Panel 24 Released with Vertical Option, New Update Mechanism

    Dash to Panel v24’s vertical option allows a single panel (combining top bar and dash) to be placed on the left or right of monitors, just like the Unity launcher of old.

    We reported that Dash to Panel vertical option was in development last month so its arrival, while welcome, shouldn’t be a surprise.

    Naturally there were a crop of design and interaction considerations to be consider to ensure the new vertical dock option works properly, including how to display the clock, and how to handle application launchers in a vertical orientation.

Security: Updates, Mozilla AMO and Reproducible Arch Linux Packages

  • Security updates for Monday

    Security updates have been issued by Debian (ampache, chromium, djvulibre, firefox-esr, gdal, and ruby-haml), Fedora (chromium, file, gd, hostapd, nspr, and rssh), openSUSE (bcm20702a1-firmware, firefox, gdal, libtomcrypt, php7, python-ecdsa, python3, samba, and thunderbird), SUSE (apache2-mod_auth_openidc, libssh2_org, and rsyslog), and Ubuntu (bash).

  • Security improvements in AMO upload tools

    We are making some changes to the submission flow for all add-ons (both AMO- and self-hosted) to improve our ability to detect malicious activity. These changes, which will go into effect later this month, will introduce a small delay in automatic approval for all submissions. The delay can be as short as a few minutes, but may take longer depending on the add-on file. If you use a version of web-ext older than 3.2.1, or a custom script that connects to AMO’s upload API, this new delay in automatic approval will likely cause a timeout error. This does not mean your upload failed; the submission will still go through and be approved shortly after the timeout notification. Your experience using these tools should remain the same otherwise.

  • Reproducible Arch Linux Packages

    Arch Linux has been involved with the reproducible builds efforts since 2016. The goal is to achieve deterministic building of software packages to enhance the security of the distribution. After almost 3 years of continued effort, along with the release of pacman 5.2 and contributions from a lot of people, we are finally able to reproduce packages distributed by Arch Linux! This enables users to build packages and compare them with the ones distributed by the Arch Linux team. Users can independently verify the work done by our packagers, and figure out if malicious code has been included in the pristine source during the build, which in turns enhances the overall supply chain security. We are one of the first binary distributions that has achieved this, and can provide tooling down to users. That was the TL;DR! The rest of the blog post will explain the reproducible builds efforts, and the technical work that has gone into achieving this.

  • Arch Linux Updates Its Kernel Installation Handling

    Arch Linux has updated the behavior when installing the linux, linux-lts, linux-zen, and linux-hardened kernel options on this popular distribution.  The actual kernel images for their official Linux, Linux LTS, Linux Zen, and Linux Hardened flavors will no longer be installed to /boot by default. By not having the actual kernel reside on /boot should help those with separate boot partitions that are quite small and avoid running out of space when keeping multiple kernels installed.

Open-spec, dual-port router offers a choice of Allwinner H3 or H5

FriendlyElec’s Linux-driven, $20 “NanoPi R1S-H3” router uses a modified version of the Allwinner H3-based NanoPi R1, upgrading the second LAN port to GbE while removing a USB port. There’s also a similar, $23 “NanoPi R1S-H5” with a quad -A53 H5. Back in February, FriendlyElec launched the community-backed NanoPi R1 router SBC, which still sells for $29. Now it has followed up with two more affordable NanoPi R1S routers based on upgraded versions of the NanoPi R1 that that give you dual GbE ports instead of 10/100Mbps and 10/1000/1000Mbps. The mainboards are smaller than the R1 at 55.6 x 52mm, and the board and the case have been entirely redesigned. Read more
