Reactions to Arch Linux's New Guided Installer
by Peter Reutemann 12 Apr '21

12 Apr '21

'Long-time Slashdot reader xiando quotes LinuxReviews: The community distribution Arch Linux has up to now required you to manually install it by entering a whole lot of scary commands in a terminal. Arch version 2021.04.01 features a new guided installer [reached by] typing python -m archinstall guided into the console you get when you boot the Arch Linux installation ISO. It is not very novice-friendly, or user-friendly, but it gets the job done and it will work fine for those with some basic GNU/Linux knowledge. Tech Radar writes that previously Arch Linux had "a rather convoluted installation process, which has given rise to a stream of Arch-based distros that are easier to install," adding that the new installer "was reportedly promoted as an official installation mechanism back in January, and was actively worked upon leading to its inclusion in the installation medium." Users have been calling on Arch Linux for simplifying the installation process for a long time, to bring it in line with other Linux distros. However, the Arch philosophy has always been to put the users in charge of every aspect of their installation, which is the antithesis of automated installers. Phoronix calls the new installer "very quick and easy," although "granted not as user-friendly / polished as say the Debian Installer, Red Hat's Anaconda installer, even Ubuntu's Subiquity, and other TUI/GUI Linux installers out there." They also note that Archinstall "does allow automatically partitioning the drive with your choice of file-system options, automatically installing a desktop environment if desired, configuring the network interfaces, and all the other basics." The method is quick enough that I'll likely use archinstall for future Arch Linux benchmarks on Phoronix as it also then applies a sane set of defaults for users... Five minutes or less and off to the races, ready for Arch Linux." But Slashdot reader I75BJC still favors "scary commands in a terminal," leaving this comment on the original submission: If you can't type with the big adults, stay on your PlayStation. Even Apple, with its very good GUI has a command line. The command line commands are more flexible, more specific, more subtle than the pointy-clicky GUI.' -- source: https://linux.slashdot.org/story/21/04/10/1755241 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/

APKPure App Contained Malicious Adware, Say Researchers
by Peter Reutemann 10 Apr '21

10 Apr '21

'Security researchers say APKPure, a widely popular app for installing older or discontinued Android apps from outside of Google's app store, contained malicious adware that flooded the victim's device with unwanted ads. From a report: Kaspersky Lab said that it alerted APKPure on Thursday that its most recent app version, 3.17.18, contained malicious code that siphoned off data from a victim's device without their knowledge, and pushed ads to the device's lock screen and in the background to generate fraudulent revenue for the adware operators. But the researchers said that the malicious code had the capacity to download other malware, potentially putting affected victims at further risk.' -- source: https://it.slashdot.org/story/21/04/09/1834230 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/

Critical Zoom Vulnerability Triggers Remote Code Execution Without User Input
by Peter Reutemann 10 Apr '21

10 Apr '21

'ZDNet: A zero-day vulnerability in Zoom which can be used to launch remote code execution (RCE) attacks has been disclosed by researchers. The researchers from Computest demonstrated a three-bug attack chain that caused an RCE on a target machine, and all without any form of user interaction. As Zoom has not yet had time to patch the critical security issue, the specific technical details of the vulnerability are being kept under wraps. However, an animation of the attack in action demonstrates how an attacker was able to open the calculator program of a machine running Zoom following its exploit. As noted by Malwarebytes, the attack works on both Windows and Mac versions of Zoom, but it has not -- yet -- been tested on iOS or Android. The browser version of the videoconferencing software is not impacted. Computest researchers Daan Keuper and Thijs Alkemade earned themselves $200,000 for this Zoom discovery, as it was part of the Pwn2Own contest. In a statement to Tom's Guide, Zoom thanked the Computest researchers and said the company was "working to mitigate this issue with respect to Zoom Chat." In-session Zoom Meetings and Zoom Video Webinars are not affected. "The attack must also originate from an accepted external contact or be a part of the target's same organizational account," Zoom added. "As a best practice, Zoom recommends that all users only accept contact requests from individuals they know and trust."' -- source: https://it.slashdot.org/story/21/04/09/209227 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/

Wix and Their Dirty Tricks
by Peter Reutemann 09 Apr '21

09 Apr '21

'Matt Mullenweg, co-founder of the open-source blogging platform WordPress, writes: Wix, the website builder company you may remember from stealing WordPress code and lying about it, has now decided the best way to gain relevance is attacking the open source WordPress community in a bizarre set of ads. They can't even come up with original concepts for attack ads, and have tried to rip-off of Apple's Mac vs PC ads, but tastelessly personify the WordPress community as an absent, drunken father in a therapy session. I have a lot of empathy for whoever was forced to work on these ads, including the actors, it must have felt bad working on something that's like Encyclopedia Britannica attacking Wikipedia. WordPress is a global movement of hundreds of thousands of volunteers and community members, coming together to make the web a better place. The code, and everything you put into it, belongs to you, and its open source license ensures that you're in complete control, now and forever. WordPress is free, and also gives you freedom. So if we're comparing website builders to abusive relationships, Wix is one that locks you in the basement and doesn't let you leave. I'm surprised consumer protection agencies haven't gone after them. Wix is a for-profit company with a valuation that peaked at around 20 billion dollars, and whose business model is getting customers to pay more and more every year and making it difficult to leave or get a refund. (Don't take my word for it, look at their investor presentations.) They are so insecure that they are also the only website creator I'm aware of that doesn't allow you to export your content, so they're like a roach motel where you can check in but never check out. Once you buy into their proprietary stack you're locked in, which even their support documentation admits.' -- source: https://it.slashdot.org/story/21/04/08/2011222 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/

IBM Creates a COBOL Compiler For Linux On x86
by Peter Reutemann 08 Apr '21

08 Apr '21

'IBM has announced a COBOL compiler for Linux on x86. "IBM COBOL for Linux on x86 1.1 brings IBM's COBOL compilation technologies and capabilities to the Linux on x86 environment," said IBM in an announcement, describing it as "the latest addition to the IBM COBOL compiler family, which includes Enterprise COBOL for z/OS and COBOL for AIX." The Register reports: COBOL -- the common business-oriented language -- has its roots in the 1950s and is synonymous with the mainframe age and difficulties paying down technical debt accrued since a bygone era of computing. So why is IBM -- which is today obsessed with hybrid clouds -- bothering to offer a COBOL compiler for Linux on x86? Because IBM thinks you may want your COBOL apps in a hybrid cloud, albeit the kind of hybrid IBM fancies, which can mean a mix of z/OS, AIX, mainframes, POWER systems and actual public clouds. [...] But the announcement also suggests IBM doesn't completely believe this COBOL on x86 Linux caper has a future as it concludes: "This solution also provides organizations with the flexibility to move workloads back to IBM Z should performance and throughput requirements increase, or to share business logic and data with CICS Transaction Server for z/OS." The new offering requires RHEL 7.8 or later, or Ubuntu Server 16.04 LTS, 18.04 LTS, or later.

Google Wins Oracle Copyright Fight as Top Court Overturns Ruling
by Peter Reutemann 07 Apr '21

07 Apr '21

'The U.S. Supreme Court ruled that Alphabet's Google didn't commit copyright infringement when it used Oracle's programming code in the Android operating system, sparing Google from what could have been a multibillion-dollar award. From a report: The 6-2 ruling, which overturns a victory for Oracle, marks a climax to a decade-old case that divided Silicon Valley and promised to reshape the rules for the software industry. Oracle was seeking as much as $9 billion. The court said Google engaged in legitimate "fair use" when it put key aspects of Oracle's Java programming language in the Android operating system. Writing for the court, Justice Stephen Breyer said Google used "only what was needed to allow users to put their accrued talents to work in a new and transformative program." Each side contended the other's position would undercut innovation. Oracle said that without strong copyright protection, companies would have less incentive to invest the large sums needed to create groundbreaking products. Google said Oracle's approach would discourage the development of new software that builds on legacy products.' -- source: https://news.slashdot.org/story/21/04/05/1448243 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/

Google Open-Sources Lyra In Beta To Reduce Voice Call Bandwidth Usage
by Peter Reutemann 07 Apr '21

07 Apr '21

'Google today open-sourced Lyra in beta, an audio codec that uses machine learning to produce high-quality voice calls. VentureBeat reports: The code and demo, which are available on GitHub, compress raw audio down to 3 kilobits per second for "quality that compares favorably to other codecs," Google says. Lyra's architecture is separated into two pieces, an encoder and decoder. When someone talks into their phone, the encoder captures distinctive attributes, called features, from their speech. Lyra extracts these features in 40-millisecond chunks and then compresses and sends them over the network. It's the decoder's job to convert the features back into an audio waveform that can be played out over the listener's phone. According to Google, Lyra's architecture is similar to traditional audio codecs, which form the backbone of internet communication. But while these traditional codecs are based on digital signal processing techniques, the key advantage for Lyra comes from the ability of its decoder to reconstruct a high-quality signal. Google believes there are a number of applications Lyra might be uniquely suited to, from archiving large amounts of speech and saving battery to alleviating network congestion in emergency situations.

Rust in the Android platform
by Peter Reutemann 07 Apr '21

07 Apr '21

'Correctness of code in the Android platform is a top priority for the security, stability, and quality of each Android release. Memory safety bugs in C and C++ continue to be the most-difficult-to-address source of incorrectness. We invest a great deal of effort and resources into detecting, fixing, and mitigating this class of bugs, and these efforts are effective in preventing a large number of bugs from making it into Android releases. Yet in spite of these efforts, memory safety bugs continue to be a top contributor of stability issues, and consistently represent ~70% of Android’s high severity security vulnerabilities. In addition to ongoing and upcoming efforts to improve detection of memory bugs, we are ramping up efforts to prevent them in the first place. Memory-safe languages are the most cost-effective means for preventing memory bugs. In addition to memory-safe languages like Kotlin and Java, we’re excited to announce that the Android Open Source Project (AOSP) now supports the Rust programming language for developing the OS itself.
