Popsicle – Multiple USB File Flasher for Linux

Filed under
Software

Popsicle is a free and open-source USB file flasher for parallelly flashing multiple USB devices. It has a simple, themeable user interface with a straightforward workflow that makes it convenient to use. Popsicle also supports USB 2 and USB 3 devices to which it can write ISO and IMG image types. It has the ability to verify ISO images with MD5 checksum or SHA256.

We’ve covered several flashing tools for creating bootable USB sticks such as WoeUSB, ISO Image Writer, Gnome Multi-Writer, Unetbootin, and Etcher, Popsicle takes the award for ease of use – and that is even when compared to Multisystem, a command-line tool for flashing multiple drives at once. Added to its feature list is the fact that it is the only official USB flashing tool available on Pop!_OS.

  • Support for Istio 1.5 has ended

    As previously announced, support for Istio 1.5 has now officially ended.

    At this point we will no longer back-port fixes for security issues and critical bugs to 1.5, so we heartily encourage you to upgrade to the latest version of Istio (1.7) if you haven’t already.

  • Kubernetes 1.19 available from Canonical

    Canonical today announced full enterprise support for Kubernetes 1.19 spanning from public cloud to the edge, covering Charmed Kubernetes, MicroK8s and kubeadm.

    “As with all releases, Canonical is committed to fast following so that users benefit from the latest features, lifecycle operations and enterprise support in line with the upstream. With Kubernetes 1.19, MicroK8s and Charmed Kubernetes also bring enhanced security and carrier grade features. Certification management, IPv6 and SR-IOV are all added across any infrastructure, whether used in development or production,” commented Alex Chalkias, Product Manager at Canonical.

    MicroK8s, the lightweight, zero-ops, opinionated Kubernetes is ideal for users that look for K8s on-rails. With support for Intel and Arm chips, MicroK8s is suited for edge environments and IoT use cases. MicroK8s 1.19 comes with new versions for add-ons such as Istio 1.5.1, Prometheus 2.20 and K8s dashboard 2.0. The Multus add-on is now generally available to handle multiple networking Kubernetes plugins simultaneously and the Ambassador add-on provides an API gateway to handle traffic between heterogeneous services. Users of the latest stable MicroK8s track will be automatically upgraded to 1.19.

    Charmed Kubernetes is best suited for enterprises looking to streamline their multi-cloud and hybrid cloud production environments by providing elastic K8s with declarative, lifecycle operations. Enterprises running critical production workloads such as telco and retail will benefit from new additions to Charmed Kubernetes 1.19. The latest version is now able to handle more fast networking scenarios with SR-IOV, IPv6 support and security is enhanced with the addition of CIS (Centre for Internet Security) benchmark compliance.

  • Easily boot multiple operating systems from a USB flash drive with Ventoy

    There are a bunch of tools that let you load an operating system onto a USB flash drive, allowing you to boot from that drive and either run or install the OS. But most of those tools are only designed to support one operating system at a time.

    Ventoy is a new tool that turns a flash drive into a multiboot system, allowing you to load as many operating system as you can fit on your flash drive. And it’s extraordinarily easy to use.

  • Annie – video downloader built with Go

    We’ve written a fair few reviews of open source software that let you download videos from YouTube and other similar services without needing to fire up a web browser. We really admired two command-line tools — youtube-dl and You-Get. We also warmly endorsed two GUI tools Tartube, and DownZemAll!. The latter has a truly sublime interface.

    We’re big advocates of command-line tools, so it seems appropriate to put a third command-line downloader tool through the mangle.

    Annie is an open source video downloader. It supports sites like YouTube, Tumblr, Vimeo, Facebook, Twitter, Instagram, TikTok, and other sites (mostly Chinese) I’ve never used. The program is written in the Go programming language.

  • Latte Dock v0.10~ | Background Radius and Shadows

    After using Kirigami ShadowedRectangle to provide background with different radius it was time to play with background shadows. So now you can adjust the background shadow size if you want.

    Notice: There is a bug with Kirigami.ShadowedRectangle; if the shadow size is bigger from any of the background width or height, the produced shadow is vastly in size. This is why Latte protects from the case and limits the shadow size to never exceed the mentioned case; more info at kde_bug#425745

    A vulnerability in Apple’s Web Share API, used to share Safari links through third-party apps, has been publicly disclosed after Apple said it wouldn’t release a fix until Spring 2021.

    The Web Share API allows users to share links to elements, such as photos, from the Safari browser through third-party applications, including any email client. A flaw found in this integration, however, could allow a hacker to configure a malicious site to attach system files to an email, in addition to the link being shared.

  • [Old] Neil Young says 16-inch MacBook Pro is 'a piece of crap' with 'Fisher-Price quality' audio

    It's a piece of crap. Are you kidding? That's Fisher-Price quality. That's like Captain Kangaroo, your new engineer. A MacBook Pro? What are you talking about? You can't get anything out of that thing. The only way you can get it out is if you put it in. And if you put it in, you can't get it out because the DAC is no good in the MacBook Pro. So you have to use an external DAC and do a bunch of stuff to make up for the problems that the MacBook Pro has because they're not aimed at quality. They're aimed at consumerism.

  • WordPress claims Apple wants 30% of App Store profits even though its free

    A founding WordPress developer accused Apple of delaying the app’s updates and bug fixes in the App Store until WordPress agrees to fork over 30% of its domain name purchases to Apple.

Announcing ASql – async Sql for Qt

Filed under
Development
KDE
Software

When developing Qt applications be it Desktop, Mobile or Web that need to talk directly with a database the use of QtSql is usually the best choice, it has many database drivers, comes ready on their installer, but has a blocking API, which means a query will block you GUI thread.

My Cutelyst Web projects also used QtSql, and for low traffic this isn’t a big issue because you are not freezing users GUI, but you are freezing the request queue instead.

One of the Cutelyst apps I developed this year has a very high traffic, and a side effect of blocking came in play, I’ve about 3k TVs connected via websockets, once a TV connects it does an authentication query, it takes ~17ms, now when there is an event PostgreSQL notifies the application which does some 20 other queries a little more expensive (~30ms) and send them to the TVs, this event also blocks the Cutelyst process.

Software

The most commonly used command line tools for process monitoring on Linux are top and its colorful, feature rich cousin htop .

To monitor temperature on Linux, you can use lm-sensors. Similarly, there are many utilities to monitor other real-time metrics such as Disk I/O, Network Stats and others.

Glances is a system monitoring tool which ties them all together and offers a lot more features. What I like the most is that you can use run Glances on a remote Linux server and monitor the system resources on your local system or monitor it through your web browser.

Here’s what it looks like. The terminal in the below screenshot has been beautified with Pywal tool that automatically changes the color based on wallpaper.

Glimpse – A Fork of the GIMP

Filed under
Software

Glimpse is a free and open-source image editor for easy-to-use expert level image manipulation. Its capabilities include transforming, cropping, and retouching photos, batch image processing, automated format conversions, and color balance correction.

Glimpse is based on the GNU Image Manipulation Program (GIMP) and built with the goal of experimenting with new ideas to expand the use of free software. A strong reason for the change in name from GIMP to Glimpse is to strip the software of all connotations that may be considered ableist and of its joke reference origin.

That notwithstanding, the Glimpse team has publicly expressed their interest in cooperating with the GNU Image Manipulation Program contributors and not competing with them. Even a portion of donations to Glimpse is passed on to the GIMP team to help facilitate progress.

Glimpse, therefore, features a major overhaul to GIMP with a new name and logo to complement a refurbished user interface. Other improvements in the latest version include the removal of unnecessary “fun” brushes, a rebranded “Gimpressionist” plug-in and text color picker, the credit of upstream contributors in the UI, a brand style overhaul and better non-English translations. Concerning customization, the ‘Gray’ UI theme and ‘Color’ icon pack are available.

The 10 Best Open-Source Video Editors

Filed under
Software

Although mainstream video editors such as Adobe Premiere Pro, Final Cut Pro, and Filmora do get the job done (and that too, quite well), their subscription packages can cost an arm and a leg. Accordingly, it won’t be wrong to say that not everyone would be able to afford such pricey software. If you feel the same way, you’re in luck as there are plenty of free and open-source video editors out there, which you can not just free but also allows making changes as per your needs if you know a thing or two about coding.
