How the Linux desktop has grown

tuxmachines.org - Čet, 08/22/2019 - 08:49

I first installed Linux in 1993. At that time, you really didn't have many options for installing the operating system. In those early days, many people simply copied a running image from someone else. Then someone had the neat idea to create a "distribution" of Linux that let you customize what software you wanted to install. That was the Softlanding Linux System (SLS) and my first introduction to Linux.

My '386 PC didn't have much memory, but it was enough. SLS 1.03 required 2MB of memory to run, or 4MB if you wanted to compile programs. If you wanted to run the X Window System, you needed a whopping 8MB of memory. And my PC had just enough memory to run X.

Intel's New OpenGL Driver Is Looking Really Great With The Upcoming Mesa 19.2

tuxmachines.org - Čet, 08/22/2019 - 01:07

Intel's new open-source OpenGL Linux driver "Iris" Gallium3D that has been in development for the past two years or so is getting ready to enter the limelight. Months ago they talked of plans to have it ready to become their default OpenGL driver by the end of the calendar year and with the state of Mesa 19.2 it's looking like that goal can be realized in time. With our new tests of this driver, in most games and other graphics applications the performance of this Gallium3D driver is now beyond that of their "classic" i965 Mesa driver.

Over the past year we've been looking a lot at the Intel Gallium3D performance and it's been a remarkable journey from the performance starting out well below their decade old OpenGL driver to now mostly exceeding that classic Mesa driver and often times by wide margins. The Intel Gallium3D driver is also largely now to feature parity in terms of OpenGL extensions and other capabilities. With all of their bases covered, this summer for the upcoming Mesa 19.2 release we've been seeing a lot of performance optimizations land. Back in April is when they indicated they hope to have it become the default by end of year 2019 and viable by Mesa 19.2.

  • Google open-sources gesture tracking AI for mobile devices

    Real-time hand shape and motion trackers are an invaluable part of sign language recognition and gesture control systems, not to mention a number of augmented reality experiences. But they’re often hobbled by occlusion and a lack of contrast patterns, preventing them from performing reliably or robustly.

    Those challenges and others motivated scientists at Google to investigate a new computer vision approach to hand perception — one bolstered by machine learning. They say that in experiments, it managed to infer up to 21 3D points of a hand (or multiple hands) on a mobile phone from just a single frame.

Open Source platforms to now help students

tuxmachines.org - Čet, 08/22/2019 - 00:30

The technical institutes in the State are now asked to use free and open-source software developed by a team, headed by the Ministry of Human Resource Development (MHRD). The MHRD has also promoted their FOSSEE (Free and Open Source Software for Education) projects which uses tools so that students can easily use them.

Recently, the MHRD made a decision that FOSSEE should be promoted amongst the student community so they can aim at reducing dependency on proprietary software in educational institutions. The MHRD Minister Ramesh Pokhriyal Nishank too took to twitter urging students to use FLOSS tools in various languages to meet academic and research requirements.

  • A guided tour of Linux file system types

    While it may not be obvious to the casual user, Linux file systems have evolved significantly over the last decade or so to make them more resistant to corruption and performance problems.

    Most Linux systems today use a file system type called ext4. The “ext” part stands for “extended” and the 4 indicates that this is the 4th generation of this file system type. Features added over time include the ability to provide increasingly larger file systems (currently as large as 1,000,000 TiB) and much larger files (up to 16 TiB), more resistance to system crashes and less fragmentation (scattering single files as chunks in multiple locations) which improves performance.

It’s designed to analyze malicious code to give security pros a better understanding of potential vulnerabilities in their networks and systems.

  • Linux Is Being Hit with Zero-Day Exploits/ Zero-Day Attacks [Ed: This is not news. If you have a system that is unpatched for months, despite many warnings, it is a risk, no matter the OS/kernel.]

    It was once the popular opinion that Linux was immune to zero-day exploits. However, even before the Equifax exploit, vulnerabilities were found in Linux distributions like Fedora and Ubuntu. In particular, back in 2016, a security researcher discovered that you could exploit a Linux system by playing a specific music file. Then, in 2017, a group of attackers used Struckshock vulnerability to carry on the attack on Equifax. These zero-day attacks are Advanced Persistent Attacks that exploit recently discovered vulnerabilities. Read on to learn more about what are zero-day exploits and how they can affect a Linux system.

  • Intel, Google, Microsoft, and others launch Confidential Computing Consortium for data security

    Major tech companies including Alibaba, Arm, Baidu, IBM, Intel, Google Cloud, Microsoft, and Red Hat today announced intent to form the Confidential Computing Consortium to improve security for data in use. Established by the Linux Foundation, the organization plans to bring together hardware vendors, developers, open source experts, and others to promote the use of confidential computing, advance common open source standards, and better protect data.

    “Confidential computing focuses on securing data in use. Current approaches to securing data often address data at rest (storage) and in transit (network), but encrypting data in use is possibly the most challenging step to providing a fully encrypted lifecycle for sensitive data,” the Linux Foundation said today in a joint statement. “Confidential computing will enable encrypted data to be processed in memory without exposing it to the rest of the system and reduce exposure for sensitive data and provide greater control and transparency for users.”

[$] OpenPOWER opens further

LWN.net - Sre, 08/21/2019 - 21:25
In what was to prove something of a theme throughout the morning, Hugh Blemings said that he had been feeling a bit like a kid waiting for Christmas recently, but that the day when the presents can be unwrapped had finally arrived. He is the executive director of the OpenPOWER Foundation and was kicking off the keynotes for the second day of the 2019 OpenPOWER Summit North America; the keynotes would reveal the "most significant and impressive announcements" in the history of the project, he said. Multiple presentations outlined a major change in the openness of the OpenPOWER instruction set architecture (ISA), along with various related hardware and software pieces; in short, OpenPOWER can be used by compliant products without paying royalties and with a grant of the patents that IBM holds on it. In addition, the foundation will be moving under the aegis of the Linux Foundation.

  • This Week in Rust 300
  • Python String Interpolation with the Percent (%) Operator

    There are a number of different ways to format strings in Python, one of which is done using the % operator, which is known as the string formatting (or interpolation) operator. In this article we'll show you how to use this operator to construct strings with a template string and variables containing your data.

  • Your Guide to the CPython Source Code

    Are there certain parts of Python that just seem magic? Like how are dictionaries so much faster than looping over a list to find an item. How does a generator remember the state of the variables each time it yields a value and why do you never have to allocate memory like other languages? It turns out, CPython, the most popular Python runtime is written in human-readable C and Python code. This tutorial will walk you through the CPython source code.

    You’ll cover all the concepts behind the internals of CPython, how they work and visual explanations as you go.

  • Python 3.8 support in PyCharm

    The release of Python 3.8 brought new features to the Python coding realm. The language is evolving according to its community’s needs by addressing cases where new syntax or logic become necessary. From new ways of assigning expressions to restriction of usage of function declarations, calls, and variable assignations, this latest release presents new options to code. Of course, PyCharm couldn’t get behind, so we now support some of the major features coming with this new version.

    This article will walk you through the features currently supported by our latest PyCharm release. To try them out, get the latest version of PyCharm and download the current beta release of Python 3.8 from here. From there you will just need to switch to Python 3.8 as your interpreter in PyCharm (if you’re not sure how to switch the interpreter, jump into our documentation for help).

  • Python Arrays in a Nutshell

    Python arrays are homogenous data structure. They are used to store multiple items but allow only the same type of data. They are available in Python by importing the array module.

    Lists, a built-in type in Python, are also capable of storing multiple values. But they are different from arrays because they are not bound to any specific type.

    So, to summarize, arrays are not fundamental type, but lists are internal to Python. An array accepts values of one kind while lists are independent of the data type.

    I’m thrilled to share this update with you today. Bryce and Brady have joined us last week and will be able to help out on Support for some of the new efforts Mozilla are working on towards creating a connected and integrated Firefox experience.

    They are going to be involved with new products, but also they won’t forget to put extra effort in providing support on forums and as well as serving as an escalation point for hard to solve issues.

  • FPR16 delays

    FPR16 was supposed to reach you in beta sometime tomorrow but I found a reproducible crash in the optimized build, probably due to one of my vain attempts to fix JavaScript bugs. I'm still investigating exactly which change(s) were responsible. We should still make the deadline (September 3) to be concurrent with the 60.9/68.1 ESRs, but there will not be much of a beta testing period and I don't anticipate it being available until probably at least Friday or Saturday. More later.

  • Classic inspired RTS Loria is now available DRM-free on GOG

    If you're like me and you enjoy a good real-time strategy game, Loria is actually pretty good. It added Linux support on Steam earlier this year and now it's also available on GOG.

    While it's inspired by titles like Warcraft II, it's not just a retro RTS. There's a few RPG-like elements including hero units, item collection, quests and more.

  • The Underlords are actually coming to Dota Underlords, plus a new Duos mode

    Valve continue to push out changes rapidly to their auto-battler Dota Underlords, with some of their upcoming plans now being detailed in a fresh update.

    One big new feature planned to be available in a few weeks is a new Duos game mode. Valve say it's a new way to play cooperatively with a friend. You party up and battle against other teams and it will support both Casual and Ranked play.

    The actual Underlords are going to be making an appearance soon too. This feature Valve said they're "excited" about, as they're a "core part of the game". They haven't said how they will work but they will "add a layer of fun and strategy to every match" so I'm very curious to see what happens.

  • Steam for China Is Called 'Zhengpi Pingtai'

    The digital games service will be run almost entirely independent of Steam and by Valve's Chinese partner company Perfect World.

Samsung Galaxy Note 10 now links up with Windows and Mac PCs via supercharged DeX app

tuxmachines.org - Sre, 08/21/2019 - 20:49

And there’s a big bonus here in the form of being able to drag-and-drop files directly from your phone to your PC, and vice versa. So you could take a photo from your Note 10 and whip it onto the PC to tweak it up in a proper heavyweight image editor, for example.

Furthermore, as XDA Developers observes, Linux on DeX is available via the DeX app, allowing you to create a container and run an Ubuntu Linux image, giving you even more flexibility and options here.

It’s not clear what Samsung intends to do in terms of giving users with older Galaxy handsets backwards compatibility, but at the moment, this is strictly a Galaxy Note 10-only affair, as mentioned.

Finally, it’s worth noting that the app does warn that your phone might get hot running the DeX application, although exactly how hot likely depends on what you’ve got the hardware doing, of course.
