Plasma Browser Integration Itinerary Integration

Filed under
KDE

Supported workflows for example include visiting a restaurant website where dropping them a call to ask for a table should be no more than two clicks away, or when surfing a trade show website, adding the dates to your calendar should be straightforward. If you want to read more about how the data gathering and processing in the background works, check out my previous blog post on the subject.

If you want to give it a try, install a recent kitinerary library (something along the lines of libkpimitinerary5), check out the itinerary branch of the plasma-browser-integration repository and follow the “How to install” instructions from source code on its wiki page. Once up and running, visit your favorite event, restaurant, and hotel sites and see if they have any structured data we can process! If you click “Inspect Element” in the popup’s context menu, the developer console will have some basic debugging information on the extractor.

Kdenlive: From Beginner to Advanced Video Editing

Filed under
KDE
HowTos

This is a different kind of video because it has a bit of Time Travel in it. In June 2019, I presented a talk at the SouthEast LinuxFest entitled “Kdenlive: From Beginner to Advanced Video Editing”. This was an interesting experience and the editing process took an excessive amount of time which I suppose is fitting for a video about video editing. In this video, you will learn some tips and tricks that I use for working in Kdenlive as well as some cool transitions like Matte Transitions. There was also a very useful Questions & Answers section at the end of the talk.

I actually learned some more things during the process of editing this video so there is always plenty to learn about this kind of software. If you would like more Kdenlive videos from me then please leave a comment below. I would be happy to make some specific tutorial videos, this is more of an overview and I think there’s plenty to show in tutorial form.

  • GNOME Shell + Mutter See Changes For Tracking Software Rendering, VNC To Toggle Animations

    GNOME Shell and Mutter saw a set of patches land today for GNOME 3.36 that have been around for a few months and deal with the tracking of software rendering and VNC usage where GNOME Shell should in turn disable animations to ease the rendering workload.

    The GNOME Settings Daemon has until now been responsible for controlling the animation heuristics when they should be disabled while now Mutter has added support for tracking software rendering situations and in turn GNOME Shell is relying upon that for determining when to disable desktop animations.

  • How not to lose the alpha channel

    Working on color imagery for QiTissue recently, I realized we were accidentally losing the alpha channel in multiple places. For efficiency reasons, we keep colors in memory using the QRgb type, and convert that to/from QString for serialization purposes via QColor as needed. Here’s what I discovered about why that doesn’t work, and some ways I fixed it.

    Firstly, be aware there is no QRgba in the Qt API . There is only QRgb, for 8bit color channels. It can hold an alpha value too, despite the lack of a trailing a in the type name. Then there is QRgba64 which uses 16bit per color channel. For our purposes, 8bit per channel is sufficient. So where do we lose the alpha channel, when QRgb can store it in principle?

  • Fosdem and Plasma Mobile Sprint

    From January 31st to February 8th I went on a little tour, first at the two days of Fosdem in Brussels, then to Berlin for a KDE sprint about Plasma Mobile.

    It was the first time i went to Fodem: it’s an awesome experience, even tough big and messy: which is the awesome of it… and the bad of it at the same time

    Even tough there were 800 talks I didn’t attend that many, some about the Elixir language, some about retrocomputing, some about iot stuff. At Fosdem the best thing to do there.. is meeting a lot of interesting people, rather than attending talks, which are very interesting never the less, which you can find videos here.

  • Norbert Preining: Okular update for Debian

    The quest for a good tabbed pdf viewer lead me okular. While Gnome3 has gone they way of “keep it stupid keep it simple” to appeal to less versed users, KDE has gone the opposite direction and provides lots of bells and knobs to configure their application. Not surprisingly, I am tending more and more to KDE apps away from the redux stuff of Gnome apps.

KDE’s Plasma Mobile Is Shaping Up Nicely on the PinePhone

KDE

Last month, we took a closer look at how UBports’ Ubuntu Touch mobile OS progressed on the PinePhone, thanks to a video shared by developer Marius Gripsgård. Now, we have a sneak peek at another great system for the PinePhone, KDE’s Plasma Mobile.

Unlike Ubuntu Touch, which is a full-fledged mobile operating system, Plasma Mobile is actually a user interface (UI) for mobile devices running on top of a GNU/Linux distribution, such as KDE neon or the Alpine Linux-based postmarketOS.

KDE
Security

Something that may have slipped you by: Back in November, the German Federal Office for Information Security approved Gpg4KDE and Gpg4win for the transmission and processing of national classified information.

Gpg4KDE is the encryption system that you use each time you encrypt and sign messages in KMail. Gpg4win, used for encrypting and signing emails on Windows, is built upon KDE's certificate manager Kleopatra. The German Government has now ranked both secure enough to be used when transmitting messages with VS-ONLY FOR SERVICE USE (VS-NfD), EU RESTRICTED and NATO RESTRICTED levels of confidentiality.

In view of the recent Rubicon/Crypto AG/CIA scandal, this is further evidence that FLOSS encryption technology is the only reliable encryption technology.

  • Season of KDE

    Since my last blog, I got really busy with my college and got less time to work on the website. I took some screenshots whenever I got the time and planned the work to be done.

    After 40 about days of coding, taking screenshots, writing documentation, the caligra website is ready, Well almost ready. The only thing that remains is the component selector in the navbar. The task of adding the selector is not that difficult, the difficult part was to add it to the KDE Jekyll theme so that it could be used by all websites old and new.

    I have managed to complete the task and submitted a merge request on the jekyll theme repository. My mentor will check it and hopefully it gets merged soon.

  • Someone is selling the free, open source Playnite launcher on Steam for $100

    Playnite is a free open source PC application designed to be an all-in-one answer to the growing number of game launchers we've all got on our desktops. In other words, it combines libraries from the likes of Steam, Epic Games Store, Uplay and GOG Galaxy, and then lets you organise them however you see fit. Jody tried it last year and came away impressed. I should emphasise the "free" above: it is available straight from the source here and, according to the site, "no features are locked behind a paywall and the complete source code is available under the MIT license". The MIT license basically surrenders the software to any kind of use with no restrictions, including resales.

  • uGet is an open source download manager for Windows and Linux that also supports Torrents and Video downloads

    The GUI has four panes, a menu bar and a toolbar. The Status pane in the top left corner displays all downloads and the ones which are Active, Queuing, Finished, and Recycled (deleted). The total number of downloads for each category is displayed next to its name, and you can click on any of these to see the list of items contained. Switch to the Category pane to jump between the default and the ones you have created. You can use the Category menu to add new sorting options, set the default download folder for each category, maximum active downloads, and also the maximum upload and download speeds. The pane below the toolbar is the download list pane; anything that you select in the status pane is displayed here. It shows the name, the file size of the download that has been completed, the total size, the progression percentage, time left to complete the download, and the upload/download speeds of each file. The View menu can be used to customize the columns that are displayed in the list pane, and the other visual elements of the program. Highlighting an item in the download list brings up its summary on the bottom pane.

  • Google ‘AutoFlip’ can resize video using AI

    The way we consume video has changed a lot over the course of the last decade. We now watch videos on our mobile devices from anywhere and because of this, video content comes in a wide variety of formats. Google recognizes this shift and so last week their AI team announced ‘AutoFlip’ an open-source framework for “intelligent video reframing.”

  • This open-source framework, ‘AutoFlip’, can do automated video cropping using AI

    Many times when we see a video on mobile devices is badly cropped, it is not much you can do about it. Understanding this problem, Google’s AI’s team has built an open-source solution on top of MediaPipe, Autoflip, which can reframe a video that fits any device or dimension (landscape, portrait, etc.). AutoFlip works in three phases. The first phase includes scene detection; the second is the video content analysis, and the third is reframing. For this tool, if a video and a target dimension are given, it analyzes the video content. Later it develops optimal tracking and cropping strategies, which finally enables it to create an output video at the same time limit in the desired aspect ratio.

  • An unofficial version of Brave browser brings native ARM64 support

    Privacy-focused Brave browser launched late last year after almost four years of being in the works. The browser is based on the Chromium open-source project and joins the likes of Microsoft Edge that is built on that platform. However, while Mozilla Firefox and Microsoft’s offering currently support ARM64 PCs natively in the stable channels, Brave does not. That might change, as Windows Insider MVP Jeremy Sinclair was able to compile an unofficial build of the open-source Brave browser that natively supports ARM64 PCs. The recompiled build (version 1.6.33) uses Microsoft’s ARM64 Chromium libraries and can run natively on those PCs like the Surface Pro X. Samsung Galaxy Book S. Native support results in improved performance and efficiency since the browser will not have to run in emulation.

  • The Brave web browser is taking on Google Chrome: Is it safe?

    The creator of Brave, Brendan Eich, also created JavaScript and co-founded the Mozilla Project that led to the development of the Firefox browser. Brave is based on the open-source Chromium browser that’s also the basis for Google’s Chrome, Opera and most recently Microsoft’s Chromium Edge browser. Open-source means that anyone can take the source code and build whatever they’d like out of it, but it doesn’t mean that all the browsers are the same. In the case of Brave, they chose to focus on user privacy by blocking trackers, scripts and ads by default. The natural by-product of blocking all this activity that usually goes unnoticed by the average user is faster load times. Brave can also make use of the wide variety of extensions for Chromium-based browsers via the Chrome Web Store at chrome.google.com.

  • This new tool could improve economic analysis of sub-national climate policies in the US

    Empowered by the Paris Agreement and a lack of national leadership on climate policy in the United States, state and local governments are leading on their own climate initiatives. California, New York and Colorado have set ambitious greenhouse gas emission and renewable energy targets for 2030. Just last week, Massachusetts introduced sweeping climate legislation targeting net zero emissions by 2050. As these environmental and energy policies move ahead, experts need to invest in economic data and tools that allow them to conduct robust economic analysis, to better inform policymakers, stakeholders and the public on how to design robust alternative climate and energy policies.

  • Are we having fund yet, npm? CTO calls for patience after devs complain promised donations platform has stalled

    At the end of August, JavaScript package registry NPM Inc said it intended "to finalize and launch an Open Source funding platform by the end of 2019." But instead of a platform, what's available at the moment might be better referred to as a feature of the npm command-line interface (CLI). The announcement was received with some skepticism at the time and the project hasn't managed to defy that expectation: There was a minor milestone last November with the addition of the "fund" command to npm v6.13.0. But not much has changed since then.

  • RcppSimdJson 0.0.2: First Update!

    RcppSimdJson wraps the fantastic simdjson library by Daniel Lemire which truly impressive. Via some very clever algorithmic engineering to obtain largely branch-free code, coupled with modern C++ and newer compiler instructions, it results in persing gigabytes of JSON parsed per second which is quite mindboggling. I highly recommend the video of the recent talk by Daniel Lemire at QCon (which was also voted best talk). The best-case performance is ‘faster than CPU speed’ as use of parallel SIMD instructions and careful branch avoidance can lead to less than one cpu cycle use per byte parsed. This release syncs the simdjson headers with upstream, and polishes the build a little by conditioning on actually having a C++17 compiler rather than just suggesting it. The NEWS entry follows.

It turns out that the video-game giant wanted a commercial agreement with Nvidia before they proceeded -- and the situation stemmed from a simple misunderstanding, Nvidia said on Thursday.

  • Inrupt, Tim Berners-Lee's Solid, and Me

    All of this is a long-winded way of saying that I have joined a company called Inrupt that is working to bring Tim Berners-Lee's distributed data ownership model that is Solid into the mainstream. (I think of Inrupt basically as the Red Hat of Solid.) I joined the Inrupt team last summer as its Chief of Security Architecture, and have been in stealth mode until now.

    The idea behind Solid is both simple and extraordinarily powerful. Your data lives in a pod that is controlled by you. Data generated by your things -- your computer, your phone, your IoT whatever -- is written to your pod. You authorize granular access to that pod to whoever you want for whatever reason you want. Your data is no longer in a bazillion places on the Internet, controlled by you-have-no-idea-who. It's yours. If you want your insurance company to have access to your fitness data, you grant it through your pod. If you want your friends to have access to your vacation photos, you grant it through your pod. If you want your thermostat to share data with your air conditioner, you give both of them access through your pod.

  • Inconsistent user-experiences with native lazy-loading images

    The specification for web browser native support for lazy-loading images landed in the HTML Living Standard a week ago. This new feature lets web developers tell the browser to defer loading an image until it is scrolled into view, or it’s about to be scrolled into view. Images account for 49 % of the median webpage’s byte size, according to the HTTP Archive. Lazy image loading can help reduce these images’ impact on page load performance. It can also help lower data costs by clients that never scroll down to images far down on a page. Historically, lazy-loading was implemented by responding to changes in the scroll position and tracking the image element’s offset from the top of the page. This could degrade page-scrolling performance. Comparatively, the new native lazy loading for images is easier to implement and doesn’t degrade scrolling performance.
