2nd New MakuluLinux Release Offers Flash and Substance

Filed under
Reviews

The MakuluLinux Flash distro is splashy and fast with a spiffy new look and new features.

MakuluLinux developer Jacque Montague Raymer on Thursday announced the second of this year's three major releases in the Series 15 distro family. The Flash edition follows last month's LinDoz edition release. The much-awaited innovative Core edition will debut between the end of November and mid-December.

MakuluLinux is a relatively new Linux OS. Its positive reputation has been developing since 2015. The three-year growth spurt involved a variety of desktop environments.

Its small developer team has delivered a surprisingly efficient and productive desktop distribution in a relatively short time period. It is unusual to see a startup rise so quickly to offer an innovative and highly competitive computing platform.

Series 15 is not an update of last year's editions. This latest release introduces some radical changes that were under development for the last two years. The Series 15 releases of LinDoz and Flash include a complete rip-and-replace rebuild on top of an in-house developed computing base. LinDoz and Flash have been reworked completely from the ground up.

Kernel: LWN Linux Articles Now Outside the Paywall

Linux
  • What's a CPU to do when it has nothing to do?

    It would be reasonable to expect doing nothing to be an easy, simple task for a kernel, but it isn't. At Kernel Recipes 2018, Rafael Wysocki discussed what CPUs do when they don't have anything to do, how the kernel handles this, problems inherent in the current strategy, and how his recent rework of the kernel's idle loop has improved power consumption on systems that aren't doing anything.

    The idle loop, one of the kernel subsystems that Wysocki maintains, controls what a CPU does when it has no processes to run. Precise to a fault, Wysocki defined his terms: for the purposes of this discussion, a CPU is an entity that can take instructions from memory and execute them at the same time as any other entities in the same system are doing likewise. On a simple, single-core single-processor system, that core is the CPU. If the processor has multiple cores, each of those cores is a CPU. If each of those cores exposes multiple interfaces for simultaneous instruction execution, which Intel calls "hyperthreading", then each of those threads is a CPU.

  • New AT_ flags for restricting pathname lookup

    System calls like openat() have access to the entire filesystem — or, at least, that part of the filesystem that exists in the current mount namespace and which the caller has the permission to access. There are times, though, when it is desirable to reduce that access, usually for reasons of security; that has proved to be especially true in many container use cases. A new patch set from Aleksa Sarai has revived an old idea: provide a set of AT_ flags that can be used to control the scope of a given pathname lookup operation.

    There have been previous attempts at restricting pathname lookup, but none of them have been merged thus far. David Drysdale posted an O_BENEATH option to openat() in 2014 that would require the eventual target to be underneath the starting directory (as provided to openat()) in the filesystem hierarchy. More recently, Al Viro suggested AT_NO_JUMPS as a way of preventing lookups from venturing outside of the current directory hierarchy or the starting directory's mount point. Both ideas have attracted interest, but neither has yet been pushed long or hard enough to make it into the mainline.

  • Some numbers from the 4.19 development cycle

    The release of 4.19-rc6 on September 30 is an indication that the 4.19 development cycle is heading toward its conclusion. Naturally, that means it's time to have a look at where the contributions for this cycle came from. The upheavals currently playing out in the kernel community do not show at this level, but there are some new faces to be seen in the top contributors this time around.

    As of this writing, 13,657 non-merge changesets have found their way into the mainline for 4.19.

  • The modernization of PCIe hotplug in Linux

    PCI Express hotplug has been supported in Linux for fourteen years. The code, which is aging, is currently undergoing a transformation to fit the needs of contemporary applications such as hot-swappable flash drives in data centers and power-manageable Thunderbolt controllers in laptops. Time for a roundup.

    The initial PCI specification from 1992 had no provisions for the addition or removal of cards at runtime. In the late 1990s and early 2000s, various proprietary hotplug controllers, as well as the vendor-neutral standard hotplug controller, were conceived and became supported by Linux through drivers living in drivers/pci/hotplug. PCI Express (PCIe), instead, supported hotplug from the get-go in 2002, but its embodiments have changed over time. Originally intended to hot-swap PCIe cards in servers or ExpressCards in laptops, today it is commonly used in data centers (where NVMe flash drives need to be swapped at runtime) and by Thunderbolt (which tunnels PCIe through a hotpluggable chain of converged I/O switches, together with other protocols such as DisplayPort).

  • Financial Services Embracing Open Source to Gain Edge in Innovation

    By now, it’s pretty much a cliché to say that all companies should be technology companies. But in the case of banks and financial services these days, it's true.

    Many finance companies are early adopters of new technologies such as blockchain, AI and Kubernetes as well as leaders in open source development. And as they seek an edge to retain customers and win new ones, they are not afraid to try new things.

    At the Linux Foundation's inaugural Open FinTech Forum here last week, attendees got a chance to discuss the latest state of open source adoption and the extent that open source strategies are changing financial service businesses.

    The fact is, banks really do have tech businesses inside of them. Capital One's DevExchange boasts several products that it has developed for internal use and also made available as open source, including the Cloud Custodian DevOps engine and the Hydrograph big data ETL tool.

  • Why the Open Source Enterprise Search Trend Will Only Accelerate

    Enterprise search has been going through a dramatic shift as of late. We've watched as some of the leaders in search, those platforms usually found in the upper right quadrant on Gartner reports, have fallen off through acquisition or from simply not keeping up with the market.

    But behind the scenes an even bigger shift is taking place: from proprietary kernels to core technologies based on open source projects.

    Some, like Lucidworks, have always been based on the open source Apache Solr project. Others, like Coveo, have joined the open source movement by offering the choice of using its traditional proprietary kernel or licensing the Coveo user experience built on top of the Elastic kernel.

The case for open source classifiers in AI algorithms

Filed under
OSS

Dr. Carol Reiley's achievements are too long to list. She co-founded Drive.ai, a self-driving car startup that raised $50 million in its second round of funding last year. Forbes magazine named her one of "20 Incredible Women in AI," and she built intelligent robot systems as a PhD candidate at Johns Hopkins University.

But when she built a voice-activated human-robot interface, her own creation couldn't recognize her voice.

Dr. Reiley used Microsoft's speech recognition API to build her interface. But since the API was built mostly by young men, it hadn't been exposed to enough voice variations. After some failed attempts to lower her voice so the system would recognize her, Dr. Reiley enlisted a male graduate to lead demonstrations of her work.

When small businesses, community organizations, and similar-sized groups realize they need software to manage their data, they think first of Microsoft Access. That may be the right choice if you're already paying for a Microsoft Office subscription or don't care that it's proprietary. But it's far from your only option—whether you prefer to use open source alternatives from a philosophical standpoint or you don't have the big budget for a Microsoft Office subscription—there are several open source database applications that are worthy alternatives to proprietary software like Microsoft Access or Apple FileMaker.

If that sounds like you, here are four open source database tools for your consideration.

Ubuntu 18.10 Set For Release Today With Some Nice Improvements

Filed under
Ubuntu

It's Cosmic Cuttlefish day! Assuming no last minute delays, Ubuntu 18.10 and its downstream flavors will be out today with their newest six-month non-LTS releases to be supported through July of 2019.

With Ubuntu 18.10 on the desktop the most user-facing change is the revised default theme for the GNOME Shell experience. The theme formerly known as "Communitheme" and now known as "Yaru" turned out fairly nice for Ubuntu 18.10 as the default appearance. While on the topic of GNOME Shell, Ubuntu 18.10 is defaulting to the X.Org Server based session like Ubuntu 18.04 LTS and they are not yet back to riding the Wayland session -- but it can be easily still toggled at log-in time for those wishing to help vet the GNOME Wayland stack.

    Lightworks, the long-standing non-linear video editing system that has offered a native Linux build the past few years after being challenged by delays for a few years, is out today with version 14.5 and comes with Linux, macOS, and Windows support.

    Lightworks 14.5 succeeds the Lightworks 14.0 release from a year and a half ago as the latest major update for this cross-platform software owned by EditShare. This new release has user-interface improvements, variable frame-rate media support, higher GPU precision settings, Reaper export support, AC-3 audio support in various formats, support for Blackmagic RAW files, and a variety of other enhancements.

  • Carnegie Mellon is Saving Old Software from Oblivion

    In early 2010, Harvard economists Carmen Reinhart and Kenneth Rogoff published an analysis of economic data from many countries and concluded that when debt levels exceed 90 percent of gross national product, a nation’s economic growth is threatened. With debt that high, expect growth to become negative, they argued.

    This analysis was done shortly after the 2008 recession, so it had enormous relevance to policymakers, many of whom were promoting high levels of debt spending in the interest of stimulating their nations’ economies. At the same time, conservative politicians, such as Olli Rehn, then an EU commissioner, and U.S. congressman Paul Ryan, used Reinhart and Rogoff’s findings to argue for fiscal austerity.

Security

Imagine you had a secret document you had to store away from prying eyes. And you have a choice: You could buy a safe made by a company that kept the workings of its locks secret. Or you could buy a safe whose manufacturer openly published the designs, letting everyone – including thieves – see how they’re made. Which would you choose?

It might seem unexpected, but as an engineering professor, I’d pick the second option. The first one might be safe – but I simply don’t know. I’d have to take the company’s word for it. Maybe it’s a reputable company with a longstanding pedigree of quality, but I’d be betting my information’s security on the company upholding its traditions. By contrast, I can judge the security of the second safe for myself – or ask an expert to evaluate it. I’ll be better informed about how secure my safe is, and therefore more confident that my document is safe inside it. That’s the value of open-source technology.

  • Another Massive Credit Reporting Database Breached By Criminals

    Lots of companies like gathering lots of data. Many do this without explicit permission from the people they're collecting from. They sell this info to others. They collect and collect and collect and it's not until there's a problem that many people seem to feel the collection itself is a problem.

    The Equifax breach is a perfectly illustrative case. Lenders wanted a service that could rate borrowers quickly to determine their trustworthiness. This required a massive amount of data to be collected from numerous creditors, along with personally-identifiable information to authenticate the gathered data. The database built by Equifax was a prime target for exploitation. That this information would ultimately end up in the hands of criminals was pretty much inevitable.

    But Equifax isn't the only credit reporting service collecting massive amounts of data but failing to properly secure it. TransUnion not only collects a lot of the same information, but it sells access to cops, lenders, private investigators, landlords… whoever might want to do one-stop shopping for personal and financial data. This includes criminals, because of course it does.

  • Searchfox in Phabricator extension

    Being able to search code while reviewing can be really useful, but unfortunately it’s not so straightforward. Many people resort to loading the patch under review in an IDE in order to be able to search code.

    Being able to do it directly in the browser can make the workflow much smoother.

    To support this use case, I’ve built an extension for Phabricator that integrates Searchfox code search functionality directly in Phabricator differentials. This way reviewers can benefit from hovers, go-to-definition and find-references without having to resort to the IDE or without having to manually navigate to the code on searchfox.org or dxr.mozilla.org. Moreover, compared to searchfox.org or dxr.mozilla.org, the extension highlights both the pre-patch view and the post-patch view, so reviewers can see how pre-existing variables/functions are being used after the patch.

  • Searching Made Faster, the Latest Firefox Exploration

    earch is one of the most common activities that people do whenever they go online. At Mozilla, we are always looking for ways to streamline that experience to make it fast, easy and convenient for our users.

    Our Firefox browser provides a variety of options for people to search the things and information they seek when they’re on the web, so we want to make search even easier. For instance, there are two search boxes on every home or new tab page – one is what we call the “awesome bar” also known as the URL bar, and the other is the search box in the home/new tab pages.

    In the awesome bar, users can use a shortcut to their queries by simply entering a predefined keyword (like @google) and typing the actual search term they are seeking, whether it’s the nearest movie theater location and times for the latest blockbuster movie or finding a sushi restaurant close to their current location. These Search Keywords have been part of the browser experience for years, yet it’s not commonly known. Here’s a hint to enable it: Go to “Preferences,” then “Search” and check “ One-Click Search Engines”.

  • GCC 9 Feature Development Is Ending Next Month

    There is just three weeks left for GNU toolchain developers to finish landing new feature material in GCC 9.0 ahead of next year's GCC 9.1 stable release.

    Richard Biener of SUSE announced today that GCC's "stage 1" development will shift to "stage 3" on 11 November. This marks the point at which open feature development is over and will then focus on bug-fixing... No new features are generally allowed in during this stage. On 6 January 2019 is when they intend to begin their final period of only working on regression fixes and documentation updates.

  • GCC's Test Suite To Begin Testing C++17 By Default

    GCC's test suite will soon begin testing the C++17 standard as part of its C++98/11/14 standard tests by default... This doesn't affect the default C++ standard used by the GCC G++ compiler at this point, but at least will help eliminate any lingering C++17 bugs as well as helping to stop regressions in the future.

    With the GCC test suite's test cases having cleared through the last of the C++17 issues, Marek Polacek of Red Hat sent out the patch today to begin testing C++17 by default when running its test suite. C++17 is tested in addition to the earlier C++98, C++11, and C++14 standards.

    Many people who regularly use computers suffer from eye strain and fatigue. Looking at a monitor for a long time can strain your eyes or can make any other problems you are having with your eyes seem more apparent. There is also research to show that late-night exposure to bright lights can affect sleep quality. This can be mitigated by reducing blue-light exposure. There are lots of simple steps you can take to reduce eye strain and fatigue. These include adjusting the brightness, contrast settings, and text size displayed, as well as minimizing glare, and ensuring your room has proper lighting. Taking regular breaks is also very important. Some monitors go further offering various eye care technologies including flicker-free technology, and an ultra-low blue light filter with different filter settings. But even if your display offers eye care technology and it’s well designed e.g. offering hotkeys that let you easily adjust filter settings. there’s still a good case to use a software solution as well. This is because the software typically offers more flexibility, such as the ability to automatically adjust the backlight and screen temperature based on the ambient brightness in your surroundings, or on a time schedule.

Mozilla: Firefox 63, TenFourFox FPR10, Servo Progress

  • Firefox 63 Released with Tab Switcher Changes, More Robust Web Extensions
    Firefox 63 is the first version of the web browser to run web extensions (previously known as add-ons) in their own processes on Linux systems. Firefox already runs “out-of-process extensions” in its Windows and Mac builds. Although largely a technical change it should lead to some tangible performance benefits, and help improve the overall security and stability of Firefox. Should an add-on crash or have a memory leak it can no longer take the rest of the browser (or its tabs) with it.
  • Cameron Kaiser: TenFourFox FPR10 available
    TenFourFox Feature Parity Release 10 final is now available (downloads, hashes, release notes). This version is live now. Other than outstanding security updates, in this version I also retracted the change (by flipping the pref) for unique data URL origins in issue 525 because of some reported add-on incompatibility. I'm looking at a way add-ons can get around this with their existing code for FPR11, but you're warned: many sites rely on this behaviour to reduce their cross-site scriping surface, and we will have to turn it back on sooner or later. The changes for FPR11 (December) and FPR12 will be smaller in scope mostly because of the holidays and my parallel work on the POWER9 JIT for Firefox on the Talos II. For the next couple FPRs I'm planning to do more ES6 work (mostly Symbol and whatever else I can shoehorn in) and to enable unique data URI origins, and possibly get requestIdleCallback into a releaseable state. Despite the slower pace, however, we will still be tracking the Firefox release schedule as usual.

RISC OS Liberated

  • Acorn Computer's RISC OS operating system finally goes fully open source
    RISC OS, the operating system that powered Acorn Computer's Archimedes computers in the 1980s and 1990s, has been fully released to open source. The move was welcomed by Raspberry Pi CEO Eben Upton: "RISC OS is a great demonstration of how much performance a well-tuned operating system and user interface can wring out of a platform. Moving to a free open source licence should bring a renewed interest to RISC OS." The shift to open source will enable the operating system to be used in new environments and markets, according to RISC OS Developments director Andrew Rawnsley. "This move unlocks a lot of opportunities for RISC OS that were previously inaccessible due to former licence restrictions. We look forward to seeing the exciting projects that this makes possible," said Rawnsley.
  • Roughly 30 years after its birth at UK's Acorn Computers, RISC OS 5 is going open source
    RISC OS was designed and developed by Acorn Computers, once dubbed the Apple of Britain, in the 1980s to run on the fledgling 32-bit Arm processor family, also designed by Acorn. Yes, the Arm that now powers the world's smartphones, embedded electronics, Internet-of-Things, and more, although it's come a long way since its mid-1980s genesis. The operating system, meanwhile, began life as the rough-around-the-edges Arthur 1.20 in 1987 for the ARM2-powered Archimedes A305 and A310, and by 1989, had morphed into the more slick RISC OS 2, written mostly in handcrafted assembly language for performance and memory-footprint reasons.
