  • London Launches Open Source App for Homebuilding

    Bryden Wood, Cast, and the Mayor of London have launched a new app to speed up the capital’s home building. The freely-available app, titled PRISM, is aimed at the design and construction of high-quality, factory-built homes to address the current demand of 50,000+ houses per year.

  • Amazon, Microsoft Wage War Over the Pentagon’s ‘War Cloud’

    Amazon and Microsoft are battling it out over a $10 billion opportunity to build the U.S. military its first “war cloud” computing system. But Amazon’s early hopes of a shock-and-awe victory may be slipping away.

    Formally called the Joint Enterprise Defense Infrastructure plan, or JEDI, the military’s computing project would store and process vast amounts of classified data, allowing the Pentagon to use artificial intelligence to speed up its war planning and fighting capabilities. The Defense Department hopes to award the winner-take-all contract as soon as August. Oracle and IBM were eliminated at an earlier round of the contract competition.

    But that’s only if the project isn’t derailed first. It faces a legal challenge by Oracle and growing congressional concerns about alleged Pentagon favoritism toward Amazon. Military officials hope to get started soon on what will be a decade-long business partnership they describe as vital to national security.

    “This is not your grandfather’s internet,” said Daniel Goure, vice president of the Lexington Institute, a defense-oriented think tank. “You’re talking about a cloud where you can go from the Pentagon literally to the soldier on the battlefield carrying classified information.”

    Amazon was considered an early favorite when the Pentagon began detailing its cloud needs in 2017, but its candidacy has been marred by an Oracle allegation that Amazon executives and the Pentagon have been overly cozy. Oracle has a final chance to make its case against Amazon — and the integrity of the government’s bidding process — in a court hearing Wednesday.

    “This is really the cloud sweepstakes, which is why there are such fierce lawsuits,” said Wedbush Securities analyst Daniel Ives.

  • Fernando Corbató, a Father of Your Computer (and Your Password), Dies at 93

    Fernando Corbató, whose work on computer time-sharing in the 1960s helped pave the way for the personal computer, as well as the computer password, died on Friday at a nursing home in Newburyport, Mass. He was 93.

    His wife, Emily Corbató, said the cause was complications of diabetes. At his death he was a professor emeritus at the Massachusetts Institute of Technology.

    Dr. Corbató, who spent his entire career at M.I.T., oversaw a project in the early 1960s called the Compatible Time-Sharing System, or C.T.S.S., which allowed multiple users in different locations to access a single computer simultaneously through telephone lines.

  • Do you need a workstation? Do you care?

    Once upon a time — a long time ago — if you needed a workstation, you knew who you were and you knew how to get it: ask IT. Alternatively: whine, bully, and demand it from IT. And the machine you got would have a RISC-based processor, a customized UNIX operating system, and would likely be a branded model and possibly customized for your job and applications.

    Microsoft allied with Intel to destroy the specialized workstation market, and thus began the long confusing story of Windows workstations.

Proprietary Software Insecurity

Mac
  • Why recent hacks show Apple’s security strength, not its weakness [Ed: Spinning bug doors as a strength? Apple has its share of liars coming to the rescue of proprietary software (not the first such bug). Moving from Microsoft to Apple "for security" is like swapping vodka for rum to cure one's liver.]

    It might be tempting to follow that line of thinking in light of two recent stories of vulnerabilities affecting the Mac and the Apple Watch. In the first instance, the Zoom video-calling app could be abused to let someone spy on you through your webcam. In the second, a flaw in Apple’s Walkie Talkie app could let a hacker eavesdrop on your iPhone conversations. They’re both troubling security issues.

  • Eavesdropping Concerns Cause Apple Watch’s Walkie-Talkie App to Be Disabled

    Just like any other Internet of things device, it’s important to remember that smartwatches are still devices. And many cool features can also be used for unethical purposes. There is always another side of the coin.

    This is what Apple Watch users found this week when Apple disabled the Walkie-Talkie app when it was discovered that it allowed users to listen in on each other’s iPhone calls without the other person’s knowledge.

  • 250M Accounts Affected By ‘TrickBot’ Trojan’s New Cookie Stealing Ability

    Popular malware TrickBot is back and this time it has learned some new capabilities like stealing cookies. So far, it has infected around 250 million Gmail accounts.

  • TrickBooster – TrickBot’s Email-Based Infection Module - Deep Instinct

    Seeing a signed malware binary delivered to a customer environment prompted us to investigate further. We analyzed the malware sample and found swaths of PowerShell code in its memory. Analysis of this PowerShell code immediately led us to the conclusion that we are dealing with a mail-bot.

  • A better zip bomb

    This article shows how to construct a non-recursive zip bomb that achieves a high compression ratio by overlapping files inside the zip container. "Non-recursive" means that it does not rely on a decompressor's recursively unpacking zip files nested within zip files: it expands fully after a single round of decompression. The output size increases quadratically in the input size, reaching a compression ratio of over 28 million (10 MB → 281 TB) at the limits of the zip format. Even greater expansion is possible using 64-bit extensions. The construction uses only the most common compression algorithm, DEFLATE, and is compatible with most zip parsers.

Software

Linux is a kernel that is currently experiencing many developments. As a user, we might want to try other kernels or upgrade the latest kernel to a computer system. Users need to be careful when changing the kernel, because this section is one of the important parts of a computer system.

But you can use Ukuu to make it easier to install and replace the kernel, because this application is an easy-to-use GUI Tool.

Based on the information I got on the Teejectech web, Starting from version 19.01, Ukuu turned into a paid license. This is because of the lack of donations needed to continue developing this application. But for those of you who have donated to Ukuu in the past, you can contact Teejeetech via email if you want to request a paid license from this application.

  • Andrei Lisita: Getting closer

    Since my last blog post I have been on a short vacation but I have also managed to make some progress on my GSoC project again with guidance from my mentor.

    Every savestate also has a creation date which is displayed in the menu, but that’s certainly not as eye-catching as the screenshots.

    There are still many missing features and things that need improving (such as the date formatting) but with every commit I feel that I am getting closer to the finished project.

  • KDE Plasma5 for Slackware, introducing Qt 5.13 in the July’19 update

    Now that all major components of the KDE software stack have fresh new releases, I bundled them for Slackware-current and voila: KDE-5_19.07.

    I have uploaded KDE-5_19.07 to my ‘ktown‘ repository. As always, these packages are meant to be installed on a full installation of Slackware-current which has had its KDE4 removed first. These packages will not work on Slackware 14.2.

  • The new userbase wiki

    When you find a kool feature in KDE software, you can write a small tutorial or just a small paragraph about it and the KDE Userbase Wiki is the right place to publish it. You don’t need to know how to code, have perfect English or know how MediaWiki’s formatting work, to contribute. We also need translators.

  • RetroArch will be Steam’s biggest emulation launch yet, coming July 30

    De Matteis tells Ars that this Steam version has been in the works "for a few months now," and he expresses specific interest in using Steamworks' Web API for future RetroArch builds. If such features are built, he says, that would create a fork in RetroArch's build distribution; until then, what you download from RetroArch's official site will be identical to the builds on Steam. (In a long-story-short explanation, De Matteis says that the Web API may prove necessary for the following red-tape reason: "There are certain licensing 'how many angels can stand on the head of a pin' issues that pertain to the Steamworks SDK and how the GPL license interprets what constitutes a system library or not.")

    [...]

    In addition to answering our questions, De Matteis coughed up one interesting bit of additional news. The 1997 N64 racing game Extreme-G may receive a retail Steam launch at an undetermined point in the future, and should this come to pass, RetroArch and its Mupen64plus emulator will power the game's Steam version. (De Matteis described this process as "talks," as opposed to a confirmed retail launch.) This would be a wholly separate download from RetroArch's free Steam download, and it would require publisher Throwback Entertainment to abide by a GPL license for the emulator front-end. "We went to great lengths to ensure all involved parties like Mupen64plus were kept in the loop on this and to make sure we got their approval," De Matteis says.

  • Cortex Command from Data Realms goes open source

    Cortex Command, a side-scrolling 2D action game originally released back in 2012 has now officially gone open source.

    In the announcement, it seems this is part of a marketing drive for their new game Planetoid Pioneers Online. Quite a nice way to do it though, I'm certainly not complaining. I think it would be great if more developers did this to their older games to help them live on.

  • Double Fine Productions have delayed Psychonauts 2 until next year, all versions still planned

    Double Fine Productions announced on their Fig campaign for Psychonauts 2 that there's going to be a delay, with it now due in 2020.

    Let's get to the good news first, they continue to confirm all previously mentioned platforms will be delivered which obviously includes the Linux version, just like they said before. As for the delay, they simply said it will be "next year" with no clear roadmap being given out yet.

  • Fate Hunters, another roguelike card-game with Linux support is leaving Early Access soon

    Another possible game to look at if you enjoy the likes of Slay the Spire, as Fate Hunters from Tower Games has Linux support.

  • OpenHMD version 0.3.0 is out, almost three years after the last version

    The team behind OpenHMD have now officially announced version 0.3.0, which comes with a huge amount of changes and new hardware support.

    What exactly is OpenHMD? Its aim is to provide a FOSS API and drivers for hardware like Virtual Reality Headsets and Controllers. They're hoping to support as many devices as they possibly can, while also being cross-platform.

    From this release they now support: 3Glasses D3 (first-party support from 3Glasses), Oculus Rift CV1 (rotational), HTC Vive and HTC Vive Pro (rotational), NOLO VR (Positional including Controller support), Windows Mixed Reality HMD support (rotational), Deepoon E2, GearVR Gen1. Sadly PSVR is currently disabled due to issues, sounds like it may return later though.

Red Hat
Ubuntu

Fedora is a free and open source Linux-based operating system that has been around since 2003. Red Hat, the world’s largest open source company prior to being bought by IBM, sponsors the project. Fedora serves as the foundation for Red Hat Enterprise Linux, a version of Linux intended for companies and servers rather than personal desktop use.

Ubuntu became the most popular Linux-based operating system not long after launching in 2004. Billionaire Mark Shuttleworth created a company called Canonical whose purpose was to create a version of Linux for general computer users. Ubuntu was that desktop.

Top 5 Linux Distros That Are Worth Your Attention

Filed under
Linux

For users who do not know, Linux is a family of open source operating systems which is available in a large number of variations which are often referred to as “distros”. The word “open source” means that every Linux user holds the right to alter or redistribute their very own customised version of Linux with or without a charge.

To make it easier to understand, the core of the OS which is the “Linux Kernel” can be referred to as a universal engine. While users have the option to choose the type of car body or the features that they desire, as per their wants and requirements. Due to its open source nature, the Linux Core is picked up by several organisations or even small group of computer nerds that have developed their very own “distro’s”. Out of hundreds of registered Linux flavours, we have compiled a list of top 5 options that you must check out.

KDE Itinerary - Vector Graphic Barcodes

Filed under
KDE

I have previously written about why we are interested in barcodes for the KItinerary extractor. This time it’s more about the how, specifically how we find and decode vector graphic barcodes in PDF files, something KItinerary wasn’t able to do until very recently.

While PDF is a vector graphics format, most barcodes we encounter in there are actually stored as images. Technically this might not be the cleanest or most efficient way, but it makes KItinerary’s life very easy: We just iterate over all images found in the PDF, and feed them into the barcode decoder.

It’s of course a bit more complicated to make this as efficient as possible, but conceptually you could script this with Poppler’s pdfimages command line tool and ZXing with just a few lines of code.

  • University of California Loses Access to New Content in Elsevier Journals

    In a statement released Wednesday, UC’s Academic Council encouraged those at the university who might require access to Elsevier’s content to use alternative access methods, such as online repositories where authors deposit free-to-read copies of their papers, and to “refrain from any new independent subscriptions to Elsevier journals.”

    Over the last few months, Elsevier has established nationwide licensing agreements in Norway and Poland, and is close to making such a deal in Hungary. However, it remains in a stalemate in negotiations with consortia of libraries and research institutions in Germany and Sweden. Those groups have also cancelled their subscriptions with the publisher.

  • Adjusting the Scope of our Security Vulnerability Disclosure Program

    At EFF we put security and privacy first. That's why over three years ago we launched EFF's Security Vulnerability Disclosure Program. The Disclosure Program is a set of guidelines on how security researchers can tell EFF about bugs in the software we develop, like HTTPS Everywhere or Certbot. When we launched the program, it was a bit of an experiment. After all, as a lean, member-driven nonprofit, we can't give out the tremendous cash rewards that large corporations can provide for zero days. Instead, all we can offer security researchers in return for their hard work is recognition on our EFF Security Hall of Fame page and other non-cash rewards like EFF gear or complimentary EFF memberships.

    Despite the limited rewards, the program has been a tremendous success. As of June 1, 2019, we've had over seventy different security researchers report valid security vulnerabilities to us, as you can see on our Security Hall of Fame page.

  • A Brighter Future is Forecast for GNOME’s Weather App

    A wave of usability improvements are on the horizon for the humble GNOME Weather app.

    The current version of the meteorological must-have might have made my list of the best weather apps for Ubuntu and Linux Mint, but I quipped “aspects of its layout bug me”.

    And it seems I’m not alone.

    [...]

    Horizontal pagination seems like a logical introduction, as does separating hourly forecasts from the 10 day forecast.

    Relaying “current conditions” remains prominent in the redesign, but not at the expense of the overall layout.

    And while I like that the proposed redesign mentions the yr.no weather service that’s used as the backend, I especially like that the client as a whole makes better use of the data that this free service provides.

  • Fork Awesome Sprites for Beast

    The Font Awesome 5 package has some other nice features though, since it’s now based on an SVG icon set, it ships 3 large sprite files that can be used to address individual icons via anchors. For Beast, I decided to stick with the Font Awesome 4 look for now, but since there are good reasons not to use icon fonts and I had the infrastructure for using sprite icons already in place, I looked into ways to generate an SVG sprite file for Font Awesome 4.

    Around February 2018, Julien Deswaef and a few others decided to fork the Font Awesome 4 project as Fork-Awesome. Since then, Fork-Awesome has incorporated new icons and also generated an SVG icon set. Since it is forked from Font Awesome, it has all the Font Awesome 4 icons and can be used as a drop in replacement.

  • F2FS Gains Native SWAP File Support, Other Improvements

    F2FS remains a very interesting file-system and has seen particularly good adoption on newer Android devices while it continues to shine as well for laptop and desktop SSD storage. With Linux 5.3 there is finally native SWAP file support for F2FS that can make use of direct I/O for better swapping performance. F2FS is also getting the ability to pre-allocate physical blocks in a pinned file to avoid fragmentation in append-only workloads, more sanity checks, and a variety of bug fixes.

  • Linux 5.3 Picks Up Support For Compressed Firmware Files - Measurable Storage Savings

    SUSE's Takashi Iwai has been working on support for loading compressed firmware files and with the Linux 5.3 driver core patches there is this support. On his own system, he started out with /lib/firmware occupying over 400MB of the disk. When making use of XZ compression, this dropped to around 130MB in total. Thus easily being able to shave off several hundred megabytes from the disk due to all these firmware blobs is an easy win.

    The firmware files remain compressed on disk while at firmware loading time into the kernel the decompression is done. Only XZ compression is currently supported. When the CONFIG_FW_LOADER_COMPRESS option is enabled, the kernel will first try to load a firmware file of the original name but otherwise falls back trying to load any file with the same name appended by the .xz extension.

Oracle security researchers have been working on security feature for Linux kernels that could protect Linux-based systems against attacks that affect Intel’s Hyper-Threading (HT) feature. Multiple side-channel threats the feature's vulnerable against, including L1TF/Foreshadow and the MDS attacks, have been revealed over the past few months.

The Oracle developers didn't specify whether or not the recent MDS attacks against Intel’s HT would also be mitigated through its Kernel Address Space Isolation (KASI), only that it will protect against L1TF/Foreshadow. Other side-channel attacks seem to be up for debate, as any extra isolation being introduced into the kernel could potentially impact the performance of Linux systems.

Google, Money and Censorship in Free Software communities

Alexander Wirt (formorer) has tried to justify censoring the mailing list in various ways. Wirt is also one of Debian's GSoC administrators and mentors, it appears he has a massive conflict of interest when censoring posts about Google. Wirt has also made public threats to censor other discussions, for example, the DebConf Israel debate. The challenges of holding a successful event in that particular region require a far more mature approach. Why are these donations and conflicts of interest hidden from the free software community who rely on, interact with contribute to Debian in so many ways? Why doesn't Debian provide a level playing field, why does money from Google get this veil of secrecy? [...] Google also operates a mailing list for mentors in Google Summer of Code. It looks a lot like any other free software community mailing list except for one thing: censorship. Look through the "Received" headers of messages on the mailing list and you can find examples of messages that were delayed for some hours waiting for approval. It is not clear how many messages were silently censored, never appearing at all. Recent attempts to discuss the issue on Google's own mailing list produced an unsurprising result: more censorship.

IBM, Red Hat and Fedora Leftovers

  • OpenShift 4: Image Builds

    One of the key differentiators of Red Hat OpenShift as a Kubernetes distribution is the ability to build container images using the platform via first class APIs. This means there is no separate infrastructure or manual build processes required to create images that will be run on the platform. Instead, the same infrastructure can be used to produce the images and run them. For developers, this means one less barrier to getting their code deployed. With OpenShift 4, we have significantly redesigned how this build infrastructure works. Before that sets off alarm bells, I should emphasize that for a consumer of the build APIs and resulting images, the experience is nearly identical. What has changed is what happens under the covers when a build is executed and source code is turned into a runnable image.

  • libinput's new thumb detection code

    The average user has approximately one thumb per hand. That thumb comes in handy for a number of touchpad interactions. For example, moving the cursor with the index finger and clicking a button with the thumb. On so-called Clickpads we don't have separate buttons though. The touchpad itself acts as a button and software decides whether it's a left, right, or middle click by counting fingers and/or finger locations. Hence the need for thumb detection, because you may have two fingers on the touchpad (usually right click) but if those are the index and thumb, then really, it's just a single finger click. libinput has had some thumb detection since the early days when we were still hand-carving bits with stone tools. But it was quite simplistic, as the old documentation illustrates: two zones on the touchpad, a touch started in the lower zone was always a thumb. Where a touch started in the upper thumb area, a timeout and movement thresholds would decide whether it was a thumb. Internally, the thumb states were, Schrödinger-esque, "NO", "YES", and "MAYBE". On top of that, we also had speed-based thumb detection - where a finger was moving fast enough, a new touch would always default to being a thumb. On the grounds that you have no business dropping fingers in the middle of a fast interaction. Such a simplistic approach worked well enough for a bunch of use-cases but failed gloriously in other cases.

  • 21 to 1: How Red Hat amplifies partner revenue

    At Red Hat Summit, we announced new research from IDC looking at the contributions of Red Hat Enterprise Linux (RHEL) to the global economy. The study, sponsored by Red Hat, found that the workloads running on Red Hat Enterprise Linux are expected to "touch" more than $10 trillion worth of global business revenues in 2019 - powering roughly 5% of the worldwide economy. While that statistic alone is eye popping, these numbers, according to the report, are only expected to grow in the coming years, fueled by more organizations embracing hybrid cloud infrastructures. As a result, there is immense opportunity for Red Hat partners and potential partners to capitalize on the growth and power of RHEL.

  • The NeuroFedora Blog: NEURON in NeuroFedora needs testing

    We have been working on including the NEURON simulator in NeuroFedora for a while now. The build process that NEURON uses has certain peculiarities that make it a little harder to build. For those that are interested in the technical details, while the main NEURON core is built using the standard ./configure; make ; make install process that cleanly differentiates the "build" and "install" phases, the Python bits are built as a "post-install hook". That is to say, they are built after the other bits in the "install" step instead of the "build" step. This implies that the build is not quite straightforward and must be slightly tweaked to ensure that the Fedora packaging guidelines are met.

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.
