Improving Your Relationship With Social Media May Call For A Targeted Approach
by Lawrence D'Oliveiro 02 Jun '22

02 Jun '22

Results of a self-experiment <https://freedom-to-tinker.com/2022/06/01/improving-your-relationship-with-s…> conducted by participants in a social networks course to find ways to improve their relationship with social media. The students split into three groups, each trying a different strategy, with the details left up to them, grouped into targeted limitation of participation in social media, targeted increase (yes, really), or elimination of participation altogether. Targeted increase involved actual posting and interaction with others on particular networks, rather than mere “doom-scrolling”. Two out of the three groups saw clear increases in well-being, and reduction in stress and loneliness. Limitation in use also improved sleep patterns. The strategy that seemed least effective was elimination: seems either limitation in use or more active participation will lead to benefits, not walking away altogether. Of course everybody is different, and as always, more research is needed. But maybe there are some ideas there you can try for yourself.

FairEmail Developer Calls It Quits After Google Falsely Flags App As Spyware
by Peter Reutemann 01 Jun '22

01 Jun '22

'"The developer of the open source email client FairEmail pulled all of his applications from Google Play and announced that he would stop development," reports gHacks. The announcement comes shortly after the developer received an email from Google stating that they believed the app was spyware. From the report: FairEmail was a popular email client for Google's Android operating system that was free to use. It was privacy-friendly, had no limitations in regards to email accounts that users could set up in the app, supported unified inbox, conversation threading, two-way synchronizing, support for OpenPGP, and a lot more. Marcel Bokhorst, the developer of the application, announced major changes to the project yesterday on XDA Developers. Earlier that week, Bokhorst received a policy violation email from Google stating that Google believed that the FairEmail application was spyware. The full statement has not been published, but Bokhorst believes that Google might have misinterpreted the use of favicons in the app. He resubmitted a new version of the application that had the use of favicons removed. The appeal he received as a response "resulted in a standard answer". While the content of the answer is unclear, it appears to have been a generic answer that Google Play Store developers have been frustrated with for a long time. Bokhorst decided to pull the application and all of his other applications from the Google Play Store. The apps won't be maintained and supported anymore according to the info. Other factors played a role in Bokhorst's decision, including the discrepancy between answering thousands of support questions per month and the application's revenue, and the inability to do something against unfair reviews in the Google Play Store. He considered keeping the applications on GitHub, but this would result in an 98% loss of audience. Google also recently forced Total Commander's developer to remove the ability to install APKs from the File Manager. If you're looking for an alternative email client, gHacks recommends the open-source app K-9 Mail.' -- source: https://tech.slashdot.org/story/22/05/19/2033249 Oh no, I just switched from K-9 to FairEmail a couple of months ago, as my K-9 was getting extremely slow with syncing mails...

Murena, the Privacy-First Android Smartphone, Arrives
by Peter Reutemann 01 Jun '22

01 Jun '22

'The /e/OS-powered Murena One is the first smartphone from Murena that does its best to free you from Google without sacrificing too many core features. There are no Google apps, Google Play Services, or even the Google Assistant. It's all been replaced by open-source software alternatives with privacy-respecting features. ZDNet's Steven Vaughan-Nichols reports: Murena and Mandrake Linux founder Gael Duval was sick of it by 2017. He wanted his data to be his data, and he wanted open-source software. Almost five years later, Duval and his co-developers launched the Murena One X2. It's the first high-end Android phone using the open-source /e/OS Android fork to arrive on the market. The privacy heart of the Murena One is /e/OS V1. There have been many attempts to create an alternative to Google-based Android and Apple's iOS -- Ubuntu One, FirefoxOS, and Windows Mobile -- but all failed. Duval's approach isn't to reinvent the mobile operating system wheel, but to clean up Android of its squeaky Google privacy-invading features and replace them with privacy-respecting ones. To make this happen, Duval started with LineageOS -- an Android-based operating system, which is descended from the failed CyanogenMod Android fork. It also blends in features from the Android Open Source Project (AOSP) source-code trees. In the /e/OS, most (but not all) Google services have been removed and replaced with MicroG services. MicroG replaces Google's libraries with purely open-source implementations without hooks to Google's services. This includes libraries and apps which provide Google Play, Maps, Geolocation, and Messaging services for Android applications. In addition, /e/OS does its best to free you from higher-level Google services. For instance, Google's default search engine has been replaced with Murena's own meta-search engine. Other internet-based services, such as Domain Name Server (DNS) and Network Time Protocol (NTP), use non-Google servers. Above the operating system, you'll find Google-free applications. This includes a web browser; an e-mail client; a messaging app; a calendar; a contact manager; and a maps app that relies on Mozilla Location Service and OpenStreetMap. While it's not here yet, Murena is also working on its own take on Google Assistant, Elivia-AI. You can also run many, but not all Android apps. You'll find these apps on the operating system's App Lounge. [...] There's still one big problem: the App Lounge still relies on you logging in with your Google account. In short, the App Lounge is mainly a gateway to Google Store apps. Munera assures me that the Lounge anonymizes your data -- except if you use apps that require payment. Still, this is annoying for people who want to cut all their ties with Google. The fundamental problem is this: Muena does all it can to separate its operating system and applications from Google, but it can't -- yet -- replace Google's e-commerce and software store system. As for hardware specs, the $379 Murena One features a 6.5-inch IPS LCD display, eight-core MediaTek Helio P60 processor, side-mounted fingerprint scanner, three rear cameras (48MP + 8MP + 5MP) and 25MP front camera, and 4,500mAh battery. It also features a microSD card slot for expandable storage and headphone port.' -- source: https://mobile.slashdot.org/story/22/05/31/229225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Python Is Getting Faster: Major Performance Tweaks On Horizon
by Lawrence D'Oliveiro 01 Jun '22

01 Jun '22

This report <https://www.theregister.com/2022/05/16/python_is_getting_faster/> on what is coming in CPython 3.11 and subsequent versions talks a lot about speed improvements. Several people have looked at removing the “GIL” (“Global Interpreter Lock”), which is the single biggest obstacle to improving multithreading performance. But some kind of lock is essential to maintain reference counting of dynamically-allocated objects. Get rid of these reference counts and you move to a Java-style pure-garbage-collected model, where you can end up consuming endless amounts of RAM unless you impose explicit limits on application size. But there is this new project called “nogil” (linked in the article). Their design overview document (hosted on Google Docs) talks about, not getting rid of reference counting, but implementing a more decentralized version of it, to minimize concurrency bottlenecks. This sounds quite hopeful.

Sick Of Windows But Can’t Afford A Mac? Consult Our Cynic’s Guide To Desktop Linux
by Lawrence D'Oliveiro 01 Jun '22

01 Jun '22

Typically snarky and tongue-in-cheek overview of Linux distros <https://www.theregister.com/2022/05/31/the_cynics_guide_to_linux/>. On ChromeOS Flex: The year of Linux on the desktop came and went, and nobody noticed – maybe because it doesn't say "Linux" on it. ChromeOS only runs on ChromeBooks and ChromeBoxes, but they outsold Macs for a while before the pandemic. ... You _can_ run Debian containers: if you know what that means, go run Debian. If you don't know what that means, trust us, you don't want to. Ubuntu: Ubuntu used to be the obvious choice, but it took its eye off the "for human beings" ball ... to grab at servers – which, to be fair, is where the money is – and it shows. When it gave up on all its in-house stuff, it kept Snap, its universal app-packaging format that no other distro uses. They work, but they gobble disk space and make bootup slower. Debian: It's sort of like Ubuntu, but more out of date, harder to install, and with fewer drivers. If that sounds just your sort of thing, go for it. Fedora: Probably not worth the effort unless your day job is trying to stop RHEL boxes falling over, or trying to build code that runs on RHEL boxes without falling over. openSUSE: ... uses Btrfs and snapshots to make it easy to roll back updates – but the package manager doesn't know about snapshots, or Btrfs's famed inability to tell you how much free disk space you have, so it occasionally fills up your file system and corrupts it. Frustrated boredom or cringing terror, it's your choice: have a lot of fun! RHEL spinoffs: Or there are Rocky Linux and AlmaLinux, which are RHEL with the serial numbers filed off. Also: only 270 entries on Distrowatch? I can remember when there were more like 350 ...

Vodafone Plans Carrier-Level User Tracking For Targeted Ads
by Peter Reutemann 01 Jun '22

01 Jun '22

'Vodafone is piloting a new advertising ID system called TrustPid, which will work as a persistent user tracker at the mobile Internet Service Provider (ISP) level. Vodafone explains that TrustPiD will be generated through randomness, and its subscribers will have the option to manage their consent over accepting the tracking via the company's Privacy Portal. BleepingComputer reports: The new system is in test phase in Germany and is intended to be impossible to bypass from within the web browser settings or through cookie blocking or IP address masking. The mobile carrier plans to assign a fixed ID to each customer and associate all user activity with it. The ID will be based on a number of parameters, so that the system will be able to maintain persistence. Then, the mobile ISP creates a personal profile based on that ID and helps advertisers serve targeted ads to each customer without disclosing any identification details. According to Vodafone, the problem that arises for its internet subscribers is that the "free" parts of the internet are threatened by stricter cookie blocking and privacy-boosting schemes. These new models threaten the targeted advertising industry, and according to Vodafone, the danger of this is losing content and platforms currently supported by ads. "Consumers appreciate the idea of a 'free' Internet, but this comes with a trade-off: publishers need a sustainable revenue model, meaning that it becomes essential to add subscription paywalls or rely on advertising to maintain free access to high-quality content," reads the explanation on the TrustPiD website, managed by Vodafone Sales and Services Limited.' -- source: https://yro.slashdot.org/story/22/05/31/2043256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Lotus 1-2-3 Ported To Linux

'Lotus-1-2-3, an ancient spreadsheet program from Lotus Software (and later IBM), has been ported to a new operating system. drewsup writes: As reported by The Register, a Lotus 1-2-3 enthusiast called Tavis Ormandy (who is also a bug-hunter for Google Project Zero), managed to successfully port the program onto Linux, which seems to be quite the feat of reverse engineering. It's important to stress that this isn't an emulated program, but rather the original 1990 Lotus 1-2 -- for x86 Unix running natively on modern x86 Linux.' -- source: https://linux.slashdot.org/story/22/05/30/1633208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Turn an Old PC Into a High-End Amiga with AmiKit'
by Peter Reutemann 30 May '22

30 May '22

'AmiKit is a compilation of pre-installed and pre-configured Amiga programs running emulated on Windows, macOS, and Linux (as well as running on classic 68K Amigas expanded with a Vampire upgrade card). Besides original Workbench (Commodore's desktop environment/graphical filemanager), AmiKit provides Directory Opus Magellan and Scalos as desktop replacements and its "Rabbit Hole" feature allows you to launch Windows, Mac or Linux applications directly from your Amiga desktop! Anti-aliased fonts, Full HD 32-bit screen modes and DualPNG Icons support is included and this package comes with exclusive versions of the Master Control Program (MCP) and MUI 5 (Magic User Interface). The original AmigaOS (version 3.x) and Kickstart ROM (version 3.1) are required, also the recently released AmigaOS 3.2 is supported. You can also get the needed files from the Amiga Forever package(s). It even supports emulating AmigaOS 4.x (for PowerPC) easily through Flower Pot. Here's an extensive overview video by Dan Wood. An Amiga Future review of an earlier 2017 version can be read here. "Everything began in 1994 when my parents bought an Amiga 500 for me and my brother," explains AmiKit's developer. "I was 14 years old..." Fast forward to 2005, the AmiKit was born — an emulated environment including more than 350 programs. It fully replaced my old Amiga and it became a legend in the community over the years. Fast forward to 2017, a brand new AmiKit X is released, originally developed for A.L.I.C.E., followed by the XE version released in 2019, Vampire edition in 2020 and Raspberry Pi in 2021. The latest & greatest version was released in 2020. When someone, who has never heard about Amiga before, asks me why I would want to turn current modern computer into something retro and old fashioned, my short answer is: "Simply because I love Amiga!"' -- source: https://slashdot.org/story/22/05/29/2232204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Linux-Based Ransomware Targets VMware Servers
by Peter Reutemann 30 May '22

30 May '22

'"Researchers at Trend Micro have discovered some new Linux-based ransomware that's being used to attack VMware ESXi servers," reports CSO Online. (They describe the ESXi servers as "a bare-metal hypervisor for creating and running several virtual machines that share the same hard drive storage.") Called Cheerscrypt, the bad app is following in the footsteps of other ransomware programs — such as LockBit, Hive and RansomEXX — that have found ESXi an efficient way to infect many computers at once with malicious payloads. Roger Grimes, a defense evangelist with security awareness training provider KnowBe4, explains that most of the world's organizations operate using VMware virtual machines. "It makes the job of ransomware attackers far easier because they can encrypt one server — the VMware server — and then encrypt every guest VM it contains. One compromise and encryption command can easily encrypt dozens to hundreds of other virtually run computers all at once." "Most VM shops use some sort of VM backup product to back up all guest servers, so finding and deleting or corrupting one backup repository kills the backup image for all the hosted guest servers all at once," Grimes adds.... The gang behind Cheerscrypt uses a "double extortion" technique to extract money from its targets, the researchers explain. "Security Alert!!!" the attackers' ransom message declares. "We hacked your company successfully. All files have been stolen and encrypted by us. If you want to restore your files or avoid file leaks, please contact us." -- source: https://linux.slashdot.org/story/22/05/28/2243237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google is Rolling Out Chrome 102 with 32 Security Fixes, One Critical
by Peter Reutemann 29 May '22

29 May '22

'This week Google began a rolling release for stable Chrome version 102 "with 32 security fixes for browser on Windows, Mac and Linux," reports ZDNet: Chrome 102 for the desktop includes 32 security fixes reported to Google by external researchers. There's one critical flaw, while eight are high severity, nine are medium severity, and seven are low severity. Google also creates other fixes for issues found through internal testing... The critical flaw, labelled as CVE-2022-1853, is a 'use after free in IndexedDB', an interface for applications to store data in a user's browser.... "My guess is that an attacker could construct a specially crafted website and take over the visitor's browser by manipulating the IndexedDB," says Pieter Arntz, a malware intelligence researcher at Malwarebytes. None of the flaws fixed in this Chrome 102 stable release were zero days, meaning flaws that were exploited before Google released a patch for it. Google's Project Zero (GPZ) team last year counted 58 zero-day exploits for popular software in 2021. Twenty-five of these were in browsers, of which 14 affected Chrome. Google engineers argue zero-day counts are rising because vendors are improving detection, fixes and disclosure. However, GPZ researchers argue the industry as a whole is not making zero days hard enough for attackers, who often rely on tweaking existing flaws rather than being forced to conjure up entirely new exploitation methods. Linux/Mac/Windows users of Chrome can check Help/About to see if the update has already rolled out to their system — or if they need to update manually.' -- source: https://it.slashdot.org/story/22/05/28/186213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
