Save Web Pages As Single HTML Files For Offline Use With Monolith (Console)

tuxmachines.org - staro 1 ura 3 min

Monolith is a command line tool to save any web page as a single HTML file that contains everything needed to render web page locally, without needing a working Internet connection.

Use this to save web pages containing documentation, wiki articles, and anything else that interests you, for local/offline use. Since the web pages are saved in plain HTML, use a tool that can search in files to quickly find the web page you're looking for.

Unlike the regular "Save page as" (or Ctrl + s) option provided by web browsers to save web pages to your computer, which saves web page assets in a folder next to the saved web page, this command line tool retrieves the web page assets and converts them into base64 data URLs, using that in the document instead of the regular URLs. As a result, page assets like Javascript, CSS or images are embedded in the page HTML, so all you need is a web browser to access the locally saved web page.

[$] Debating the Cryptographic Autonomy License

LWN.net - Pet, 08/23/2019 - 21:28
If one were to ask a group of free-software developers whether the community needs more software licenses, the majority of the group would almost certainly answer "no". We have the licenses we need to express a range of views of software freedom, and adding to the list just tends to create confusion and compatibility issues. That does not stop people from writing new licenses, though. While much of the "innovation" in software licenses in recent times is focused on giving copyright holders more control over how others use their code (while still being able to brand it "open source"), there are exceptions. The proposed "Cryptographic Autonomy License" (CAL) is one of those; its purpose is to give users of the code control over the data that is processed with it.

  • Cantor and the support for Jupyter notebooks at the finish line

    Hello everyone! It's been almost three weeks since my last post and this is going to be my my final post in this blog. So, I want to summarize all my work done in this GSoC project. Just to remember again, the goal of the project was to add the support for Jupiter notebooks to Cantor. This format is widely used in the scientific and education areas, mostly by the application Jupyter, and there is a lot of content available on the internet in this format (for example, here). By adding the support of this format in Cantor we’ll allow Cantor users access this content. This is short description, if you more intersted, you can found more details in my proporsal.

    [...]

    This is all for the limitations, I think. Let's talk about future plans and perspectives. In my opinion, this project has reached its initial goals, is finished now and will only need maintenance and support in terms of bug fixing and adjustment to potential format changes in future.

    When talking more generally, this project is part of the current overall development activities in Cantor to improve the usability and the stability of the application and to extend the feature set in order to enable more workflows and to reach to a bigger audience with this. See 19.08 and 18.12 release announcements to read more about the developments in the recent releases of Cantor. Support of the Jupyter notebook format is a big step into this direction but this not all. We have already many other items in our backlog like for the UX improvements, plots integration improvements going into this direction. Some of this items will be addressed soon. Some of them are something for the next GSoC project next year maybe?

    I think, that's all for now. Thank you for reading this blog and thank you for your interest in my project. Working on this project was a very interesting and pleasant period of my life. I am happy that I had this opportunity and was able to contribute to KDE and especially to Cantor with the support of my mentor Alexander Semke.

  • My Open-Source Activities from January to August 2019

    Debian is a general-purpose Linux distribution that is widely used on the planet. I am a Debian Developer who works on packages related to Android SDK and the Java ecosystem.

    I started a new package in an attempt to build the Android framework android.jar using the upstream build systems involving Ninja, Soong and others. Since the beginning we have been writing our own (very simple) makefiles to build the binaries in AOSP because their build logic tends to be simple and straightforward, until we worked on android.jar. Building it requires digging in so much code that it became incredibly hard to maintain, which is why we still haven’t brought in any newer version since android-framework-23. This is problematic as developers can’t build any apps that target Android 7+.

    After a month of work, this package is finally done. After all its dependencies are packaged in the future, it will be good to upload. This is where the students of Google Summer of Code (GSoC) come in!

  • Dive into the life and legacy of Alan Turing: 5 books and more

    Another well-known fact about Turing was his conviction for "gross indecency" because of his homosexuality, and the posthumous apology and pardon issued over more a half a decade after Turing’s death.

    But beyond all of this, who was Alan Turing?

    Here are six books that delve deeply into the life and legacy of Alan Turing. Collectively, these books cover his life, both professional and personal, and work others have done to build upon Turing’s ideas. Individually, or collectively, these works allow the reader to learn who Alan Turing was beyond just a few well-known, broad-stroke themes.

28 facts about Linux for its 28th birthday

tuxmachines.org - Pet, 08/23/2019 - 18:26

Nearly three decades ago, Linus Torvalds sent the email announcing Linux, a free operating system that was "just a hobby" and not "big and professional like GNU." It's fair to say that Linux has had an enormous influence on technology and the world in general in the 28 years since Torvalds announced it. Most people already know the "origin story" of Linux, though. Here's 28 things about Linux (the kernel and larger ecosystem) you may not already know.

1 - Linux isn't very useful alone, so folks took to creating Linux distributions to bundle user software with it, make it usable and easier to install. The first Linux distribution was Softlanding Linux System (SLS), first released in 1992 and using the .96p4 Linux kernel.

You could buy it on 5.25" or 3.5" floppies, or CD-ROM if you were high-tech. If you wanted a GUI, you needed at least 8MB of RAM.

2 - SLS didn't last, but it influenced Slackware Linux, which was first released in 1993 and is still under development today. Slackware is the oldest surviving Linux distribution and celebrated its 26th birthday on July 17th this year.

3 - Linux has the largest install base of any general purpose operating system. It powers everything from all 500 of the Top 500 Supercomputers to Android phones, Chomebooks, and all manner of embedded devices and things like the Kindle eBook readers and smart televisions. (Also the laptop used to write this post.)

LibreOffice 6.3 - Waiting for a miracle

tuxmachines.org - Pet, 08/23/2019 - 18:18

LibreOffice 6.3 is a powerful, rich office suite, and the fact it comes with no strings attached, the string to your purse included, is a commendable thing. But it is not enough. Simply isn't. Functionality is what matters, and if the program cannot satisfy the necessary needs, it's not really useful. Maybe on the scale of un-value, it's less un-valuable than something that costs a lot of money, but you still don't get what you require.

And in this regard, LibreOffice 6.3 doesn't quite cut it. I mean, you can still use it happily - I know I will, it does an okay job, and you can create files and export to PDF and all that. But then, working with Office files is pretty much a no-go, the style management is inefficient, and the UI layouts are somewhat clunky. I also feel the momentum has slowed, and the great, amazing hope that was there when LibreOffice was born is just a thing of mildly apathetic momentum now. True, this ailment grips the entire open-source world, and Linux in particular, but it doesn't change the fact that the hope is slowly dwindling. All in all, worth testing, but a solution to all office problems, LibreOffice 6.3 ain't.

AMD Ryzen 5 3400G Is Working Well On Linux

tuxmachines.org - Pet, 08/23/2019 - 18:12

AMD Raven Ridge APUs were a rough launch particularly on Linux where even with the latest motherboard BIOS updates and Linux kernel I am still hitting occasional stability issues, so when the opportunity arose recently to try out the Ryzen 5 3400G as the successor in the Picasso family, I was interested. Fortunately, AMD Picasso APUs have proven to be in better shape on Linux so here is the initial round of performance tests for those interested in the AMD Linux performance on Ubuntu.

The Ryzen 5 3400G is a $150 USD APU and while launched alongside the new Zen 2 CPUs, the Ryzen 3000 series APUs are in fact based on Zen+ and using Vega graphics. The Ryzen 5 3400G features four cores / eight threads with a 3.7GHz base frequency and 4.2GHz turbo frequency. On the graphics side are Radeon RX Vega 11 graphics that clock up to 1.4GHz as a nice boost over the Ryzen 5 2400G. This AM4 APU has a 65 Watt TDP for this highest-performing Picasso socketed APU.

Linux on your laptop: A closer look at EFI boot options

tuxmachines.org - Pet, 08/23/2019 - 18:10

For some time now I have gotten a slow but steady volume of requests that I write about UEFI firmware and EFI boot relative to installing and maintaining Linux. As a result of a casual comment I made in a recent post about installing Linux on a new laptop, the volume has gone up considerably.

So in this post I will review and explain some of what I consider to be the most important points about UEFI firmware and Linux systems. I intend for this to be a relatively short post, but once I get started you never know... so you might want to get a cup of coffee before starting to read.

First, the specific aspect of UEFI firmware that I am concerned with here is the boot sequence, and how to use it with Linux. There is a lot more to UEFI (EFI) than that, but I will not be addressing any of that here.

  • Intel Submits Final Batch Of Graphics Driver Changes For Linux 5.4 - Growing Tiger Lake

    After having been submitting various feature updates to DRM-Next the past few weeks of new graphics driver feature code to introduce in Linux 5.4, a final pull request was sent in today with the remaining feature work slated for this next version of the Linux kernel.

    As added earlier to Linux 5.4, the big focus at this stage for the open-source Intel Linux developers is on bringing up the "Gen 12" graphics support for Tiger Lake. With the Icelake / Gen 11 graphics support now in good shape, the developers have already been busy plumbing Gen 12 graphics that are at least a year out from being available through retail channels.

  • Nouveau's Changes Sent Out For Linux 5.4 In Fixing Up The Open-Source NVIDIA Support

    While NVIDIA recently began publishing more hardware documentation, don't expect it to make an immediate difference in the quality of the open-source NVIDIA "Nouveau" driver. Today the pull request was sent to DRM-Next of the Nouveau kernel driver changes for the upcoming Linux 5.4 cycle and there isn't much to get excited about.

    Nouveau DRM maintainer Ben Skeggs of Red Hat sent in the pull request this morning, which mostly consists of work that missed out on the current Linux 5.3 cycle when he sent in that earlier pull request too late. This time the pull request is on-time and has the improvements to color management, some code for acknowledging when any PCIe power cables are not connected, and different fixes. But for end-users, nothing to get excited about unless any of the bug fixes had affected problems you experienced.

Linux Virtual Machine App GNOME Boxes Has An Awesome Time-Saving Feature You Should Know About

tuxmachines.org - Pet, 08/23/2019 - 17:44

Not only did GNOME Boxes automatically detect that the ISO contained Ubuntu 18.04 LTS, it offered me an Express Install option (provided I had a working internet connection). The app automatically pulled my username into the account field, and asked that I do nothing more than enter a password to proceed.

And that was truly all that it required, unless I needed to customize the amount of RAM and disk space allocated to the VM.

After hitting the Continue button, GNOME Boxes ran an unattended installation. It pulled regional and language settings from my host machine, handled the partitioning dialogue, and everything else. The installation screens zoomed by, components and updates were downloaded, and within less than 5 minutes I had a perfectly working Ubuntu 18.04 to play with.
