Trisquel GNU/Linux 9.0 Is Here for Those Who Seek 100% Freedom for Their PCs

Filed under
Linux

Trisquel GNU/Linux 9.0 is based on Ubuntu 18.04.5 LTS (Bionic Beaver) and it’s powered by the GNU Linux-libre kernel. To offer users a 100% free operating system, it uses a version of Ubuntu’s 4.15 kernel that doesn’t contain any proprietary code.

Of course, this release updates all packages to their latest versions, and includes backports to provide users with top-notch hardware support. Also, Trisquel’s default web browser Abrowser, a version of Mozilla’s popular Firefox web browser that respects the freedom and privacy of users, received a major update, based on Firefox 81.

Unity Desktop Review: Good for the Nostalgic Ubuntu Users

Filed under
Reviews
Ubuntu

Continuing with our series of Linux Desktop Environment reviews, we’re going back to a classic. The Unity is just as much a blast from the past as MATE. This review covers the Unity Desktop: first impressions, the user experience, some notable features, and some recommendations on who should use it.

When I first boot into Unity, I’m struck by how much it looks like GNOME and Budgie. This makes sense, as Unity is a graphical shell that sits on top of the GNOME Desktop Environment (rather than GNOME Shell), and it does offer some separate features that are different than GNOME Shell.

Debian-Based DebEX Linux Now Ships with GNOME 3.38 and Linux Kernel 5.9

Filed under
Linux

Based on the Debian Testing repositories, where the development of the upcoming Debian GNU/Linux 11 “Bullseye” operating system series takes place, the new DebEX Linux release is here with goodies that no other live Linux distribution currently offers.

For starters, the developer removed the lightweight MATE desktop environment, which was used in previous DebEX versions, and replaced it with the latest GNOME 3.38 desktop environment. So that right there might be a very good reason for many wanting to try GNOME 3.38 on Debian GNU/Linux to download this distro.

Further Exploring The Intel Tiger Lake Core i7-1165G7 Performance On Ubuntu Linux

Filed under
Graphics/Benchmarks

Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.

  • From Continuous Compliance to Continuous Risk Mitigation

    The explosive adoption of open source has meant that companies are having to take open source risk assessment and mitigation seriously. As open source contributions and usage grow, the attack surface for vulnerabilities has increased considerably, leading to higher security risk. In fact, Forrester’s 2018 Global Business Technographics Security Survey revealed that 35% of global security decision makers who experienced an external breach said that it occurred due to software vulnerabilities.

  • Three years since the Polhem prize | daniel.haxx.se

    Today, exactly three years ago, I received flowers, money and a gold medal at a grand prize ceremony that will forever live on in my mind and memory. I was awarded the Polhem Prize for my decades of work on curl. The prize itself was handed over to me by no one else than the Swedish king himself. One of the absolute top honors I can imagine in my little home country.

    In some aspects, my life is divided into the life before this event and the life after. The prize has even made little me being presented on a poster in the Technical Museum in Stockholm. The medal itself still sits on my work desk and if I just stop starring at my monitors for a moment and glance a little over to the left – I can see it. I think the prize made my surroundings, my family and friends get a slightly different view and realization of what I actually do all these hours in front of my screens.

    In the tree years since I received the prize, we’ve increased the total number of contributors and authors in curl by 50%. We’ve done over 3,700 commits and 25 releases since then. Upwards and onward.

    Life moved on. It was not “peak curl”. There was no “prize curse” that left us unable to keep up the pace and development. It was possibly a “peak life moment” there for me personally. As an open source maintainer, I can’t imagine many bigger honors or awards to come my way ever again, but I’m not complaining. I got the prize and I still smile when I think about it.

  • Louis-Philippe Véronneau - Musings on long-term software support and economic incentives

    Although I still read a lot, during my college sophomore years my reading habits shifted from novels to more academic works. Indeed, reading dry textbooks and economic papers for classes often kept me from reading anything else substantial. Nowadays, I tend to binge read novels: I won't touch a book for months on end, and suddenly, I'll read 10 novels back to back.

    At the start of a novel binge, I always follow the same ritual: I take out my e-reader from its storage box, marvel at the fact the battery is still pretty full, turn on the WiFi and check if there are OS updates. And I have to admit, Kobo Inc. (now Rakuten Kobo) has done a stellar job of keeping my e-reader up to date. I've owned this model (a Kobo Aura 1st generation) for 7 years now and I'm still running the latest version of Kobo's Linux-based OS.

  • FSFE at SFSCon 2020 - FSFE

    The South Tyrol Free Software Conference, SFSCon, is one of Europe’s most established annual conferences on Free Software. In recent years we have been represented with talks, workshops and our information booth. Last year we also organised our Community Event in the context of SFSCon, so that we could meet not only our community but also many interested people and report about our work.

    Due to the current situation, the SFSCon 2020 can unfortunately only take place in blended mode: both online and at NOI Techpark, for a limited number of people. But of course, the FSFE is again contributing to the programme.

    The FSFE has organised several talks in which legal issues are clarified and current political developments are analysed. Concrete practical questions concerning compliance, for example for SMEs, will be addressed as well as questions about machine learning and which problems arise in the development of a free smartphone.

  • Intense weeks

    End of October turns out to be one of the highs when it comes to workload this year. Everything happens at once – there are two public events that I’d like to tell you about.

    The first one is running lights. This is an annual running competition organized by AIF Friidrott, the sports club my kids are active in. This year, this means organized by me and postponed due to COVID-19, but the virtual races started this weekend and the arena race will take place on the 24th.

    If anyone of you are in the Alingsås area and enjoy I highly recommend you to join. The weather looks nice, and we will light up the arena with live fire, so it will be a great evening.

    The second one is the foss-north 2020 take II event. This spring, we decided to try to organize a physical foss-north event this fall, as obviously the pandemic must be over by November. This seems to not be the case. Smile

  • Community Member Monday: Marcin Popko - The Document Foundation Blog

    Hello! I’m from Bialystok, a city in north-east Poland. I work as an electromagnetic compatibility tester – it’s a seriously crazy and interesting area of electronics development. I’m quite an artist soul; in my free time I dance bachata and sing in a folk band called “Kurpie Zielone”. I also write a blog about dance, emotions and technology here.

    What is the free software/Linux/LibreOffice scene like in Poland?

    FLOSS (free/libre and open source software) has rather more awareness in geeky and technological domains, than in everyday normal life. LibreOffice is not well know among my friends – some of them are using Microsoft Office, and some of them are even using OpenOffice. So that’s my mission here: inform them Smile Companies use LibreOffice when they can’t afford Microsoft Office or when it’s not seriously needed.

    Why did you start using Python?

    My interest in data analytics and data science lead me to Python. Being a high level language it was easy to learn python. Python requires proper indentation as part of the syntax — if you don’t use indentation correctly, your program won’t work. This makes it readable from the get go

    Also Python has a large standard library plus thousands of open-source 3rd party libraries, which meant that I could develop code more with less effort, since many of the tools they needed, are ready to be plugged in and used.

  • SDL2 Gains OS/2 Support - LinuxReviews

    The year was 1997 when two very well-dressed young men appeared at the The Gathering demoscene party held a large hall called Vikingskipet (The Viking Ship) in Norway. The men looked around and then they started handing out CD-Rom coasters to anyone who would accept. The coasters were labelled OS/2 Warp 4 and the men assured me that it was the latest and greatest version of what would surely be the dominant operating system in the near future. These were not "pirated" or illegitimate coasters, they were genuine copies of OS/2 printed by IBM. They were trying to get the kids hooked. It didn't work and OS/2 died off only a few short years later.

    IBM released the last OS/2 version, 4.52, in December 2001. Two companies have kept their own proprietary versions of it alive: eComStation, from Serenity Systems and Mensys BV, and ArcaOS, from Arca Noae LLC, are still being sold and to some degree maintained. Both are binary compatible with OS/2 Warp 4. ArcaOS is the most "developed" of the two, it has had several new releases this year.

  • How open source leads to open doors [Ed: Well, it’s a good thing they don’t know what racist IBM did at the beginning]

    In today’s climate, racial equality and equity is top of mind. The tech industry has a renewed focus on giving girls in underrepresented communities access and exposure to STEM, particularly in the pre-teen and teen years that are critical to keeping girls interested in STEM subjects. Giving adolescent girls access to skills like coding and introducing them to open source prepares them for college and career and opens new doors and opportunities

    [...]

    As part of our continuing social justice efforts and commitment to racially equality, IBM is awarding our next open source community grant to Black Girls CODE. Launched in 2011, Black Girls CODE (BGC), with 15 chapter cities in the U.S. and abroad, is a transformative global movement that hosts technology-focused weekend workshops, hackathons, summer camps, and many other enrichment opportunities for more than 20,000 low-income, Black girls — or as they call themselves, Tech Divas.

    Additionally, IBM has partnered with Black Girls CODE as a National Alumnae Ambassador Program Sponsor to help cultivate the next generation of STEM developers. This partnership allows Black Girls CODE and their Tech Divas to participate in two initial opportunities with IBM — one with IBM’s Call for Code for Racial Justice program and another with IBM offerings for workshops on STEM topics like quantum, artificial intelligence, and hybrid cloud.

  • How To Hide Your Location On Chrome, Firefox, and Edge

    Sought after web browsers like Firefox, Chrome, and Microsoft Edge are enabled with geolocation services that can be used to trace you based on your network location, IP address, and WiFi.

    Although this feature is useful enough, at the same time it may cause grave privacy concerns. Therefore, it becomes imperative to fake or hides your location from these popular browsers.

    Geolocation indicates your location and then links it with your web browser or the applications you are using. Many services use your IP address and connected networks to get the information and sync it with the known locations.

    There are many reasons for which these browsers use your location. At times when you visit some website, you might get notified to confirm your current location and acquire data relevant to your location. Nevertheless, if you wish to hide your location due to some reasons such as when you wish to stay safe from malicious activities i.e. want to access data that is location restricted, this article will be of great help to you!

    File transfer between a Computer and a mobile can be done in various methods and using various protocols. Today, we will see a whole new, different approach. This guide explains how to transfer files between computers and mobile devices by scanning QR codes. Yes, you read that right! Say hello to Qrcp, formerly known as Qr-filetransfer, a simple command line file transfer application used to send and receive files over WiFi between a Linux system and a mobile phone by scanning a QR code, without leaving the Terminal.

    When sending files, Qrcp will bind a web server to the address of your WiFi network interface card on a random port and create a handler for it. The default handler will serve the content and exit the program once the transfer is complete. Similarly, when receiving files, qrcp serves an upload page and handles the transfer.

A little background on why this problem emerged — Ever noticed when a computer or a website asks you to enter the last two digits of the year?

    Computers are programmed to store only the last two digits of years because it saves storage space (Four digits Vs. Two digits). Say there’s only one day left in the year 1999 (99); a day later, the systems would fail to understand if it’s the Year 2000 (00) or 1900 (00).

  • Linux 5.9.1 And Older Stable Kernel Updates Fixing "Bleeding Tooth" Bluetooth Vulnerability Are Available - LinuxReviews

    BleedingTooth is a really bad and in theory very serious Linux kernel vulnerability. It allows someone within Bluetooth range to potentially execute code on your Linux machine thanks to a combination of improper input validation, improper buffer restrictions and improper access control in the BlueZ libraries and heap-based type confusion in the Linux kernel's L2CAP code. The practical threat isn't all that.

    Linux 5.9.1 as well as updates to the older "stable" kernel series (5.8.16, 5.4.72, 4.19.152, 4.14.202, 4.9.240, and 4.4.240) have been released with a patch by Intel's Luiz Augusto von Dentz addressing the Linux kernel side of the BleedingTooth vulnerability. You should upgrade to one of those if your machine has a Bluetooth adapter (most laptops do).

  • -ck hacking: linux-5.9-ck1, MuQSS version 0.204 for linux-5.9

    Unfortunately these past few months have been marred by lockdown and family issues, culminating in the ultimate death of my father just over a month ago (unrelated to covid19 but made that much worse because of its effects on everything in our city) so linux kernel was the furthest thing from my mind and a 5.8 resync never happened. He'll be sorely missed, and if this were something more substantial I'd dedicate it towards him but it doesn't do him justice.

    Announcing a new -ck release, 5.9-ck1  with the latest version of the Multiple Queue Skiplist Scheduler, version 0.204 These are patches designed to improve system responsiveness and interactivity with specific emphasis on the desktop, but configurable for any workload.

    Independent Linux kernel developer Con Kolivas (and retired anaesthetist) is back on track with a new update to his "CK" patch-set and the MuQSS scheduler. 

    The retired doctor had taken some time off from his kernel development hobby earlier this year to help design equipment for the COVID-19 battle. He did manage to release his updated patches for Linux 5.7 but has been becoming increasingly concerned over the size of the Linux kernel and his ability in the future to continue maintaining these independent patches as a result. Making the matters worse, his father passed away (non-COVID) and that further complicated his development work.

Ubuntu

Both Ubuntu and Pop!OS is great for beginners as well as professionals. Like how the budget Android devices ship with a lot of bloatware, Ubuntu also ships with bloatware, resulting in a relatively poor user experience and performance compared to Pop!_OS.

Ubuntu also comes with “Ubuntu Minimal options” that don’t include many applications letting you install what you actually need. Apart from that, Ubuntu’s software center has a built-in section for snap applications, whereas you won’t find snap packages in the Pop!_OS shop rather you’ll find the Flatpak package option.

However, Snap packages take too much space on the disk; hence, we suggest you consider using the APT version of any application. Pop!_OS also has its own official PPA, where you can find applications like TensorFlow and Android Studio one “apt-get install” away from installing.

  • Manage your Linux backups with Rdiffweb | Opensource.com

    The Rdiffweb app offers a simplified web interface for easy management of rdiff-backup, software that offers robust automatic backups from one Linux computer (client) to another Linux computer (server) using secure shell (SSH), thus maximizing your disk space. The free, open source online tool helps save time when accessing rdiff-backup archives, recovering data, and managing administrators. Recently, rdiff-backup received a major update with a host of new features when it was migrated to Python 3.

    In this article, I'll show you a basic way to set up rdiff-backup with Rdiffweb. Before getting started, you should know enough network basics to identify a Linux computer's IP address and set up an SSH connection.

Unity Desktop Review: Good for the Nostalgic Ubuntu Users

Continuing with our series of Linux Desktop Environment reviews, we’re going back to a classic. The Unity is just as much a blast from the past as MATE. This review covers the Unity Desktop: first impressions, the user experience, some notable features, and some recommendations on who should use it. When I first boot into Unity, I’m struck by how much it looks like GNOME and Budgie. This makes sense, as Unity is a graphical shell that sits on top of the GNOME Desktop Environment (rather than GNOME Shell), and it does offer some separate features that are different than GNOME Shell.

Debian-Based DebEX Linux Now Ships with GNOME 3.38 and Linux Kernel 5.9

Based on the Debian Testing repositories, where the development of the upcoming Debian GNU/Linux 11 “Bullseye” operating system series takes place, the new DebEX Linux release is here with goodies that no other live Linux distribution currently offers. For starters, the developer removed the lightweight MATE desktop environment, which was used in previous DebEX versions, and replaced it with the latest GNOME 3.38 desktop environment. So that right there might be a very good reason for many wanting to try GNOME 3.38 on Debian GNU/Linux to download this distro. Read more

Further Exploring The Intel Tiger Lake Core i7-1165G7 Performance On Ubuntu Linux

Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.

Free Software and OSS Leftovers

  • From Continuous Compliance to Continuous Risk Mitigation

    The explosive adoption of open source has meant that companies are having to take open source risk assessment and mitigation seriously. As open source contributions and usage grow, the attack surface for vulnerabilities has increased considerably, leading to higher security risk. In fact, Forrester’s 2018 Global Business Technographics Security Survey revealed that 35% of global security decision makers who experienced an external breach said that it occurred due to software vulnerabilities.

  • Three years since the Polhem prize | daniel.haxx.se

    Today, exactly three years ago, I received flowers, money and a gold medal at a grand prize ceremony that will forever live on in my mind and memory. I was awarded the Polhem Prize for my decades of work on curl. The prize itself was handed over to me by no one else than the Swedish king himself. One of the absolute top honors I can imagine in my little home country. In some aspects, my life is divided into the life before this event and the life after. The prize has even made little me being presented on a poster in the Technical Museum in Stockholm. The medal itself still sits on my work desk and if I just stop starring at my monitors for a moment and glance a little over to the left – I can see it. I think the prize made my surroundings, my family and friends get a slightly different view and realization of what I actually do all these hours in front of my screens. In the tree years since I received the prize, we’ve increased the total number of contributors and authors in curl by 50%. We’ve done over 3,700 commits and 25 releases since then. Upwards and onward. Life moved on. It was not “peak curl”. There was no “prize curse” that left us unable to keep up the pace and development. It was possibly a “peak life moment” there for me personally. As an open source maintainer, I can’t imagine many bigger honors or awards to come my way ever again, but I’m not complaining. I got the prize and I still smile when I think about it.

  • Louis-Philippe Véronneau - Musings on long-term software support and economic incentives

    Although I still read a lot, during my college sophomore years my reading habits shifted from novels to more academic works. Indeed, reading dry textbooks and economic papers for classes often kept me from reading anything else substantial. Nowadays, I tend to binge read novels: I won't touch a book for months on end, and suddenly, I'll read 10 novels back to back. At the start of a novel binge, I always follow the same ritual: I take out my e-reader from its storage box, marvel at the fact the battery is still pretty full, turn on the WiFi and check if there are OS updates. And I have to admit, Kobo Inc. (now Rakuten Kobo) has done a stellar job of keeping my e-reader up to date. I've owned this model (a Kobo Aura 1st generation) for 7 years now and I'm still running the latest version of Kobo's Linux-based OS.

  • FSFE at SFSCon 2020 - FSFE

    The South Tyrol Free Software Conference, SFSCon, is one of Europe’s most established annual conferences on Free Software. In recent years we have been represented with talks, workshops and our information booth. Last year we also organised our Community Event in the context of SFSCon, so that we could meet not only our community but also many interested people and report about our work. Due to the current situation, the SFSCon 2020 can unfortunately only take place in blended mode: both online and at NOI Techpark, for a limited number of people. But of course, the FSFE is again contributing to the programme. The FSFE has organised several talks in which legal issues are clarified and current political developments are analysed. Concrete practical questions concerning compliance, for example for SMEs, will be addressed as well as questions about machine learning and which problems arise in the development of a free smartphone.

  • Intense weeks

    End of October turns out to be one of the highs when it comes to workload this year. Everything happens at once – there are two public events that I’d like to tell you about. The first one is running lights. This is an annual running competition organized by AIF Friidrott, the sports club my kids are active in. This year, this means organized by me and postponed due to COVID-19, but the virtual races started this weekend and the arena race will take place on the 24th. If anyone of you are in the Alingsås area and enjoy I highly recommend you to join. The weather looks nice, and we will light up the arena with live fire, so it will be a great evening. The second one is the foss-north 2020 take II event. This spring, we decided to try to organize a physical foss-north event this fall, as obviously the pandemic must be over by November. This seems to not be the case. :-)

  • Community Member Monday: Marcin Popko - The Document Foundation Blog

    Hello! I’m from Bialystok, a city in north-east Poland. I work as an electromagnetic compatibility tester – it’s a seriously crazy and interesting area of electronics development. I’m quite an artist soul; in my free time I dance bachata and sing in a folk band called “Kurpie Zielone”. I also write a blog about dance, emotions and technology here. What is the free software/Linux/LibreOffice scene like in Poland? FLOSS (free/libre and open source software) has rather more awareness in geeky and technological domains, than in everyday normal life. LibreOffice is not well know among my friends – some of them are using Microsoft Office, and some of them are even using OpenOffice. So that’s my mission here: inform them :-) Companies use LibreOffice when they can’t afford Microsoft Office or when it’s not seriously needed.
