Multi-touch Gestures in elementary OS 6

Filed under
OS

One of the most hotly requested features for years has been to have multi-touch gestures in elementary OS, and with 6.0 I’m excited to say that we will deliver. Like the dark style preference, delivering a great multi-touch experience is a little more complicated than it seems on the surface. There have been some 3rd party tools to detect touchpad gestures and then trigger actions after-the-fact, but it wasn’t until recently that we’ve had the technical ability to provide smooth, responsive animations that track 1:1 with your finger movement across a touchpad or touch screen.

We’ve had the great pleasure of working with José Expósito, the author of Touchégg, on our window manager gestures. In elementary OS 6, we use Touchégg Daemon behind the scenes to capture input events and communicate them to Gala, our window manager.

Development
Linux

The rise of streaming services like Netflix made people speculate about the dim future of TV channels. While the newer generation might not watch TV anymore, TV channels are not out of fashion, yet.

Many streaming services like Hulu and Hotstar include TV channels in their offering. TV channels are also utilizing live streaming to broadcast their content to viewers on the internet.

Another way to watch live TV is by using IPTV. There are a number of TV channels available via IPTV so that viewers can use internet to watch the live broadcast. Some channels are available for free while some might require subscription.

Budgie 10.5.2 Desktop Environment Released with Support for the GNOME 3.38 Stack

Filed under
News

More than a year in the works, Budgie 10.5.2 is here with a wide range of changes, starting with support for GNOME Project’s latest GNOME 3.38 stack. However, Budgie still supports the older GNOME 3.36 stack to make it easier for Linux OS maintainers to backport it to older operating systems.

The biggest new feature in this release is the new desktop icons implementation called Budgie Desktop View. While an initial release, it already supports single (default) or double-click for launching items. However, future releases will bring drag and drop support, keyboard navigation, and GTK4 support.

Canonical Releases Major Ubuntu Kernel Updates to Address 14 Vulnerabilities

Filed under
Security

A total of 14 security vulnerabilities have been fixed in these new major Ubuntu kernel updates, including a race condition (CVE-2020-0423) that may lead to a use-after-free vulnerability, discovered in Linux kernel’s binder IPC implementation. This flaw affects Ubuntu 20.10, Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS systems, and could allow a local attacker to cause a denial of service (system crash) or possibly execute arbitrary code.

Affecting all supported Ubuntu releases, this kernel update addresses a Bluetooth security vulnerability (CVE-2020-10135) discovered by Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen, which could allow a physically proximate attacker to impersonate a previously paired Bluetooth device.

  • Day 2: Perl is dead. Long live Perl and Raku. – Raku Advent Calendar

    ‘Perl is dead’, is a meme that’s just plain wrong. Perl isn’t dead. It’s just dead to some programmers. Complicated regexes? Sigils? There’s more than one way to do it (TMTOWTDI)? Sometimes when programmers encounter Perl in the wild they react with fear. “WTF!?”, they cry! But fear needn’t be a Perl killer. If you take the time to see past Perl’s imperfections and walk the learning curve, there are rich rewards: Perl is an imperfect but pragmatic and expressive language that for 30+ years has helped programmers get the job done.

    When Larry Wall designed Raku he fixed most of Perl’s imperfections and doubled down on Perl’s DNA. Perl values pragmatism, expressivity, and whipupitude and Raku does too! Why stop at sigils ($@%) when you can have twice the fun with twigils ($!, %!, @! etc)?

    For some programmers, however, the mere sight of a twigil can induce fear. Like Perl, Raku’s expressive power is a double-edged sword – potentially stopping other programmers in their tracks. A Raku programmer’s, “DWIM” (do what I mean) can be another programmer’s “WAT!?”

  • Deriving Patterns of Fraud from the Enron Dataset

  • Qt Quick MultiEffect

    If you read the recent Qt Marketplace blog post, you may have noticed that something called Qt Quick MultiEffect has become available. This blog post gives more details on what Quick MultiEffect actually is and why you might want to consider using it in your Qt Quick projects.

    Let's start with a bit of background information. Qt Graphical Effects module contains a set of effects which can be used in Qt Quick user interfaces. These cover blur, shadow, mask, contrast etc. effects which can be easily applied into Quick items. When you need a single effect, these are great. But when you want to use multiple effects at the same time, performance is not optimal, because each effect renders into FBO texture which next effect then uses as its source. Because of this separation of effects, shaders also can't share calculations and textures. So multiple Qt Graphical Effects increase GPU and memory usage a bit more than desired.

  • Librem 14 Status Update: EVT2 Sample Is Almost There – Purism

    We truly think of the Librem 14 as our dream laptop here at Purism, and because of that and because this is a brand new design compared to the Librem 13 we find ourselves nitpicking a bit more than usual as our design becomes a reality.

    As part of this nitpicking process we make EVT (Engineering Verification Test) samples which allow us not only to fine-tune our manufacturing process, it also allows us to physically examine the laptop. Using kill switches, using the keyboard, examining the print on the case and keyboard–all these and other tests help us refine things so that the final product is something we are proud of. In addition to the more cosmetic bugs we list below, it also helps us find larger bugs. For instance we discovered issues not just with the microphone but also an issue that limited the 2nd SO-DIMM slot to 16GB RAM. We needed to re-do the PCB to address both of these issues.

    We know a lot of people have been interested to see pictures of the actual Librem 14 instead of just renders. We have made the second round of EVT samples a few weeks ago and have finally gotten a chance to take some high-quality pictures to share. We are almost there! There are just a few more tweaks we want to make that will only add a few weeks to our shipping plan, but we think it’s important to get everything perfect. With the holidays this will likely mean shipping won’t start until the beginning of January.

    Here’s my (fourteenth) monthly update about the activities I’ve done in the F/L/OSS world.

    [...]

    This was my 23rd month of contributing to Debian. I became a DM in late March last year and a DD last Christmas! \o/

    Apart from doing a bunch of activitites like attending KubeCon + RubyConf (blog to follow!), et al and simultaneously giving my undergrad exams, I did (relatively) more work than I had really anticipated!

  • FOSS Activities in November 2020

    Second month of doing these posts. In short not much has been happening the past weeks, but that would be a slight lie.

    I have sponsored rgacognes Trusted User application. The application was posted to the mailing list, and it’s currently being voted and decided by a weeks time.

    There has also been some discussion for years about bringing debug packages into Arch. This has largely been stalled but I brought it back to life again. Essentially the problem might be solved by utilizing the new debuginfod project, and we can later distribute the packages itself when we understand the new mirror requirements. There is currently a discussion on [arch-dev-public] about it.

    Along with the above, chugging along nicely with packages. Python has been rebuilt for the Python 3.9 release. This means there hasn’t been as many python package updates. Currently everything is in testing and we should see packages move to the stable repositories early next week. I simply haven’t been bothered going through the hoops of releasing package updates into stable and then deal with a rebuild for python 3.9 for testing.

  • Internet Explorer fails to make the cut, banished from Microsoft Teams for good

    As of today, the Microsoft Teams web app no longer supports Internet Explorer 11, as the Windows giant foretold in August.

    Microsoft says that customers using IE 11 with Teams can expect either degraded capabilities or the inability to connect at all. Redmond noted earlier this year that Teams usage had surged with so many people working from home during the COVID-19 pandemic.

    The end of Teams support for Internet Explorer is a prelude for a broader abandonment of Microsoft's legacy browser planned for August 17, 2021, when the other Microsoft 365 apps and services shut the door on the creaking software.

  • ‘The Joe Rogan Experience’ Is Spotify’s Most Popular Podcast

    There’s a reason Spotify shelled out millions to bring Joe Rogan’s podcast exclusively to its platform. The Joe Rogan Experience was the most popular podcast on Spotify in 2020, the audio streamer revealed as part of its year-end Wrapped campaign.

    Spotify has been investing aggressively into podcasts in recent years, buying up audio-first studios and striking exclusive deals with top podcasters. In May, the company made its biggest bet yet on a podcasting personality when it inked a reported $100 million deal with Rogan to bring his show to its listeners.

    The often controversial Joe Rogan Experience hit Spotify on Sept. 1 and becomes exclusive to the platform in December. After making its debut on Spotify, it quickly rocketed to the top of the service’s podcast rankings and, in just three months, has become the most popular audio show of 2020 among its global listenership.

  • Python Queue – Linux Hint

    Python provides many built-in modules, functions, and statements that help the programmers to perform various complicated tasks easily. It also provides many built-in data structures like lists, tuple, and dictionaries, which ensure the efficient creation and management of data in applications. A queue is a data structure that stores and manages the data. It stores the data in a first-in, first-out (FIFO) order. The element that is inserted first will be removed first. We can understand the working of the queue from our daily life example. It‘s like a queue of customers; the customer who comes first is facilitated first.

  • Python Multi-line Comments – Linux Hint

    Every programming language provides a mechanism to add comments to projects. Comments are the simple lines in computer programs that are ignored by the compiler or interpreter. Comments are often written in natural language to increase programmer comprehensibility. Developers use comments to ignore some parts of the code in the debugging or testing phase.

    Writing comments in Python can be very simple, and creating a comment in Python begins with the ‘#’ symbol. This article explains how to create multi-line comments in Python.

  • How to Join Lists in Python – Linux Hint

    Lists are an important data structure in Python, used to store multiple elements in a single container. Python lists can store both similar types and heterogeneous types of elements. In Python, you can join or concatenate two or more lists. Joining a list merges numerous lists into a single list. This article explains the joining or concatenation of Python lists in several ways.

  • Python Zip File – Linux Hint

    Python is a general-purpose programming language. It is widely used in machine learning, deep learning, artificial intelligence, and data sciences projects. Python is loaded with handy built-in modules, functions, and statements. Therefore, it helps the programmers a lot to perform many types of tasks. Performing the file related task in Python is super easy due to the availability of related modules. We can perform any type of file-related tasks, i.e., reading, writing, searching, and deleting a file.

    ZIP is a popular format of files that offers lossless compression. A ZIP file contains one or many compressed files and is a single file. The compression algorithms ensure that we can recreate the actual data from the compressed data without any loss. There are several benefits of using the zip file. By using the zip files, we can put all the related data in one single file with reduced file size. Encryption can also be applied while creating zip files. ZIP files are mostly created and used when we need to transfer data through online sources like social media applications and email. It ensures the fastest delivery of data. Python provides a built-in zipfile module to work on the ZIP files. In this guide, we will learn to perform various zip file-related tasks with examples.

  • Python Global Variables – Linux Hint

    In programming language, variables are used to store information. For example, in developing a student management software system, the name, email, and age of a student will be stored in the respective variables. Like other programming languages, Python has both global and local variables. In Python, global variables are declared outside of the function and can be used everywhere in the program. This article explains global variables in Python in detail with some examples.

    The scope of the global variable is very wide, and it is not limited to any specific function. These variables can be used both inside and outside of the function for storing and retrieving information.

  • Python getattr( ) Function – Linux Hint

    The vast variety of Python built-in modules, functions, and statements helps programmers to perform various tasks. The getattr() function is a Python built-in function that allows programmers to access the attribute value of an object. If the value is not found, then the getattar() function returns the default value. This is the reason why the getattr() function is used mostly to access the attribute values of objects. This article will provide a detailed explanation of the getattr() function with some examples.

  • How to Enable and Disable Nginx Cache – Linux Hint

    When you have enabled caching in Nginx Plus, it stores responses in a cache disk, and these are further used to respond to clients without holding a proxy request for every time with the same content. Nginx Plus’s caching has more capabilities in which the most useful features, such as cache purging, delayed caching, and dynamic content caching, are included.

    In this article, we will learn more about caching, such as how to enable and disable the caching in an Nginx server on a Linux system.

  • Multiple Ways to Transfer Files Between Your Computer and Cloud Linux Server – Linux Hint

    SCP is a utility used to move files and directories securely via SSH. With the SCP command, you can transfer files from your computer to your Linux server and vice versa. As this utility uses SSH to move files, you’ll need the SSH credential of your server to transfer files.

    SSH comes pre-installed on most Linux servers, but if not, you can install and enable it using the following steps.

  • How Do I Create a Reverse Proxy in Nginx? – Linux Hint

    The standard proxy server only works according to their client’s requests by providing filtering and content privacy. When we talk about the reverse proxy server, it works on behalf of server requests, used for intercepting and routing traffic to a separate server. This proxy feature is useful for load distribution and improves performance among various available servers. It shows all the content which it takes from different online sites. Using the proxy method, you can pass requests for processing to the server applications over specified protocols other than HTTP.

    There are many reasons due to which you might install the reverse proxy. One important reason is content privacy. The reverse proxy method provides a single centralized point to contact with clients. It can give you the centralized logging feature and can report across several servers. Nginx quickly processes the static content and passes dynamic requests to the Apache server; this feature improves the overall performance.

  • How to Untar Files in Linux – Linux Hint

    Tar is quite a popular archive format, especially on Linux. In many cases, distros use tar archives to deliver package updates. Tar archives are also common to find when it comes to sharing files online.

    Check out how to untar files in Linux.

  • How to Configure GUI on your EC2 Instance – Linux Hint

    There are two different types of interfaces to interact with an operating system that is a Graphical User Interface (GUI) and Command Line Interface (CLI). In the Command Line Interface, we interact with the system directly using system commands on the terminal. We give commands to the system, then the system executes operating system functions according to the given commands, and we receive responses from the system in the form of simple text. The command-line interface is not commonly used by beginners. It is mostly used by developers and system administrators to configure systems and install packages as using Command Line Interface is much faster than using Graphical User Interface. Also, tasks can be automated by writing simple scripts (bash script for Linux and batch scripts for windows) using a command-line interface. We can perform way more functions using the command line interface.

    For GUI, we have a nice representation of files and folders in the operating system using icons and indicators. It is much easier for non-professionals to use a graphical user interface instead of a command-line interface.

  • Nginx SSL Setup in Linux – Linux Hint

    SSL (stands for secure socket layer) is a web protocol that makes the traffic between server and client secure by encrypting it. Server and clients safely transmit the traffic without the risk of communication being interpreted by third parties. It also helps the client to verify the identity of the website they are communicating with.

    In this post, we will describe how to setup SSL for Nginx. We will be demonstrating the procedure using the self-signed certificate. A self-signed certificate only encrypts the connection but does not validate the identity of your server. Therefore, it should be used only for testing environments or for internal LAN services. For the production environment, it is better to use the certificates signed by CA (certificate authority).

  • How to Enable KVM Kernel Module on Raspberry Pi OS? – Linux Hint

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

    Earlier it was impossible to get KVM running on the Raspberry Pi using the Raspberry Pi OS (also known as Raspbian). This is because KVM only works on a 64-bit operating system. Raspberry Pi OS was a 32-bit operating system. Another reason was that Raspberry Pi 3 and earlier models had only 1 GB of memory, and this is insufficient to run KVM. Docker was a better solution for devices with 1 GB of memory.

    At the time of this writing, it is possible to run KVM on the Raspberry Pi using the Raspberry Pi OS. Because Raspberry Pi OS officially ships with a 64-bit kernel, and the Raspberry Pi 4 has an 8 GB model (it has 8 GB of memory). Sadly, the 64-bit Raspberry Pi OS kernel is not enabled by default. You have to enable it manually.

  • How to Install and Use GNOME Tweaks to Customize Your Linux Desktop – Linux Hint

    If you have been using a Linux distribution with a GNOME based desktop environment for a long time, you must be aware about the transition of GNOME 2 / GTK2 libraries to GNOME Shell / GTK3. With the advent of GNOME Shell, many useful settings that existed in GNOME 2 based desktop environments were removed, hidden or relocated, making it difficult for the average user to find these settings. This article will discuss a tool called “GNOME Tweaks” or “GNOME Tweak Tool” that reveals some of these settings to end users in GNOME Shell based Linux distributions like Ubuntu. These settings are usually not available in main system settings (also known as GNOME Control Center).

  • How to Get my IP Address in Linux – Linux Hint

    In networking, an IP address is a label assigned to a computer connected to the network. In that network, an IP address identifies a unique device. It enables devices to communicate with each other over an IP-based network like the internet or LAN.

    In the case of Linux, there are multiple tools that you can use to check the IP address. Some of the tools come pre-installed with most of the distros; some don’t.

    Check out how to get IP address in Linux.

  • Blender Animation Export – Linux Hint

    Blender is a popular 3D modeling tool. Along with modeling, it offers the entire production pipeline of 3D creation, and that includes shading, texturing, compositing, video editing, and animation. Animations are the most effective way to communicate and convey the message. It has now become a marketing tool, and many businesses are getting benefitted from it.

  • How to Back Up Your Data in Ubuntu – Linux Hint

    In the present era, technology has become a core part of our lives, as devices such as smartphones, computers, tablets, and more are being used every day. As technology becomes more and more advanced, it has turned out to be a huge blessing for us as our lives are becoming easier and much more efficient.

    However, the Internet has also paved way for issues such as data breaches and identify theft, which, as time goes on, have become increasingly more frequent and more hostile. Our data is constantly under threat of becoming exposed and leaked. Even if security breaches do not occur, there are often cases where data is lost due to accidental deletion or hard drive crashing, which can cause users to lose their valuable stored information. It is imperative to implement backup strategies to keep a record of your data and avoid losing all your information. This article shows you how to back up your data in the Ubuntu operating system.

  • Intel Begins Preparing Linux Graphics Driver Support For Xe HP As "Gen12.5" - Phoronix

    Xe HP is Intel's discrete GPU aiming to compete against the latest-generation AMD and NVIDIA compute accelerators. Xe HP isn't scheduled to reach general availability until well into 2021 while now as they begin ramping up their sampling of Xe HP to potential customers, the Linux open-source driver support is preparing to roll-out.

    While Xe HP is about scaling up Intel Xe Graphics (Gen12), the Xe HP driver support is introducing it as a new "Gen12.5" target rather than just "Gen12" that is used by Tiger Lake / Rocket Lake / Xe LP.

  • NVIDIA Is Working On DMA-BUF Passing That Should Help Improve Their Wayland Support

    NVIDIA is working on allowing their proprietary driver to support passing buffers as DMA-BUF. In turn this should allow for better supporting their proprietary driver on Wayland compared to the EGLStreams mess.

    A Phoronix reader tipped us off to NVIDIA developer comments last month in response to a KDE EGLStreams bug. A bug report was opened regarding that restarting the compositing breaks the EGLStreams back-end for KDE's KWin.

  • Mesa Now 2~5x Faster For SPECViewPerf Following OpenGL Optimizations - Phoronix

    Well known open-source AMD Linux graphics driver developer Marek Olšák has just merged one of his largest set of optimizations in recent times: 2~5x faster performance for SPECViewPerf.

    SPECViewPerf is the common industry benchmark for measuring graphics performance for professional applications with benchmark viewsets from 3ds Max, CATIA, Maya, Solidworks, Siemens NX, and other programs. The performance when using Mesa drivers have been lagging but now thanks to common Mesa infrastructure improvements by Mesa, the performance is wildly improved.

  • Adopting open source in the face of fragmentation - Techerati

    Open source fragmentation is enabling innovation and efficiency, but also increasing security risks, writes Lech Sandecki, Product Manager at Canonical – the publisher of Ubuntu

    In 2020, 99 percent of enterprise codebases contain open source components. Businesses have come to realise that the collective approach of open source toward innovation has incredible benefits, and will help them to integrate technologies such as cloud computing, artificial intelligence (AI), machine-learning (ML), and microservices into their solutions.

    But with this goldrush, which has brought a sharp rise in new applications, it’s becoming more difficult to see, or simply just to know, how many open source components are involved. This fragmentation is consequently hurting compliance officers, who are unable to keep up with the software supply chain. These same officers are struggling with visibility and cannot keep up pace.

    The challenge is that the landscape is unrecognisable from just a decade ago. Back then, a much smaller pool of commercial open source vendors licensed their software to customers, understood everything about the code, and dealt with every security patch.

  • When you need the numbers just right – benchmark and profiling applications in the Snap Store | Ubuntu

    The world of software is a vast and complex one, often too difficult to easily assess by human intuition alone. Which is why detailed and accurate measurements of software behavior are essential in helping us understand and gauge how well our applications perform. The Snap Store has a fair share of productivity tools and utilities, including a wide range of benchmarking and profiling tools. These are designed to help developers, system administrators and hardcore enthusiasts get a precise sense of their software, whether as part of research and design or for troubleshooting ongoing problems in production environments. Let’s have a little tour.

  • Add a subcommand showing GNU Guix history of all packages

    Hello, everyone! I'm Magali and for the next three months, I'll be an Outreachy intern in the GNU Guix community. As part of my Outreachy application process, I made my first ever contribution to Free Software adding a package to Guix, and since then I'm eager to begin contributing even more. My task for this three-month period is to add a subcommand showing the history of all packages. Although Guix makes it possible to install and have an older version of a package, it isn't as easy to find, for example, the commit related to these versions. The subcommand I'll implement will be something like guix git log. The idea is that, for instance, when the user invokes guix git log --oneline | grep msmtp, a list with all the commits, one per line, related to msmtp, will be shown.

  • Bpytop on openSUSE

    I recently published an article about how great Bashtop is on openSUSE, and when I was nearly done with it, I was told about Bpytop. Since I was going through the final edit, I didn’t just want to dump what I did before but rather, follow it up with Bpytop. I am not sure how far behind the curve I am now and maybe there is something even cooler out there but before anyone tells me what the latest hotness is in terminal, system monitoring applications, I am feverishly writing about this What is so great about Bpytop? If you are a nerd about what your system is doing and like to see the numbers, charts graphs, etc, and you have previously enjoyed Bashtop, Bpytop is going to send tingles of joy down your finger tips. The little bits of information it gives you from CPU load, load average, and frequency is superb. The chart it produces on the CPU usage looks fantastic and really makes you wonder how they accomplished this when it is only in text mode. Truly a feat of terminal engineering!

  • Work-around in Linux to switch between single-sided and double-sided printing | Fitzcarraldo's Blog

    I use Gentoo Linux on my laptop, and have drivers installed for quite a few printer manufacturers and models, as I work in multiple offices and they have a wide range of printers and MFPs. To date I have had no trouble printing single-sided (‘simplex’) and double-sided (‘duplex’) documents on the printers that support duplex printing. However, one of the offices I have been working in recently has a Konica Minolta bizhub C368, a floor-standing MFP, and the printer in this MFP did not enable me to switch between single-sided and double-sided printing even though Windows users in the same office could. This article explains how I managed to switch between the two printing modes.
