Linux On Mars: NASA’s Ingenuity Helicopter Flies

by Lawrence D'Oliveiro

The first powered aircraft on Mars <https://www.theregister.com/2021/04/19/perseverance_computing_feature/> has proved its concept, taken flight for a few seconds, and made a controlled landing again. The control system is running Linux on a Qualcomm Snapdragon 801 chip, not because NASA considered it the best tool for the job, but because it was the easiest solution available. The hardware “is tuned for use on Earth, not Mars”, so it is only planned to make brief flights of no more than 90 seconds at a time, always landing back at the same spot, and it is not expected to endure beyond the initial 30 days of the Perseverance mission.

Openwall Releases 'Linux Kernel Runtime Guard' 0.9.0

by Peter Reutemann

'Long-time Slashdot reader xiando shares news from LinuxReviews: Linux Kernel Runtime Guard (LKRG) is a security module for the Linux kernel developed by Openwall. The latest release adds compatibility with Linux kernels up to soon to be released 5.12, support for building LKRG into kernel images, support for old 32-bit x86 machines and more... The Linux Kernel Runtime Guard is an out-of-tree kernel module you can install as a kernel module, or, with the 0.9.0 release, build into your Linux kernel. It does run-time integrity checks to detect security vulnerability exploits against the Linux kernel. An Openwall developer also notes in the announcement that "During LKRG development and testing I've found 7 Linux kernel bugs, 4 of them have CVE numbers."' -- source: https://news.slashdot.org/story/21/04/17/2118236 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/

Debian Votes to Issue No Statement on Stallman's Return to the FSF Board

by Peter Reutemann

'Debian Project Secretary Kurt Roeckx has announced the results of a closely-watched vote on what statement would be made about Richard Stallman's readmission to the Free Software Foundation's board. Seven options were considered, with the Debian project's 420 voting developers also asked to rank their preferred outcomes: - Option 1: "Call for the FSF board removal, as in rms-open-letter.github.io" - Option 2: "Call for Stallman's resignation from all FSF bodies" - Option 3: "Discourage collaboration with the FSF while Stallman is in a leading position" - Option 4: "Call on the FSF to further its governance processes" - Option 5: "Support Stallman's reinstatement, as in rms-support-letter.github.io" - Option 6: "Denounce the witch-hunt against RMS and the FSF" - Option 7: "Debian will not issue a public statement on this issue" While all seven options achieved a quorum of votes, two failed to achieve a majority — options 5 and 6. ("Support Stallman's reinstatement" and "Denounce the witch-hunt...") The option receiving the most votes was #7 (not issuing a public statement) — but it wasn't that simple. The vote's final outcome was determined by comparing every possible pair of options to determine which option would still be preferred by a majority of voters in each possible comparision. In this case, that winner was still the option which had also received the most votes: Debian will not issue a public statement on this issue. The Debian Project will not issue a public statement on whether Richard Stallman should be removed from leadership positions or not. Any individual (including Debian members) wishing to (co-)sign any of the open letters on this subject is invited to do this in a personal capacity. The results are captured in an elaborate graph. Numbers inside the ovals show the final ratio of yes to no votes (so a number higher than 1.00 indicates a majority, with much higher numbers indicating much larger majorities). Numbers outside the ovals (along the lines) indicate the number of voters who'd preferred the winning choice over the losing choice (toward which the arrow is pointing). The winning option is highlighted in blue.' -- source: https://linux.slashdot.org/story/21/04/18/1727209 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/

Linus Torvalds Says Rust Closer for Linux Kernel Development, Calls C++ 'A Crap Language'

by Peter Reutemann

'Google's Android team supports Rust for developing the Android operating system. Now they're also helping evaluate Rust for Linux kernel development. Their hopes, among other things, are that "New code written in Rust has a reduced risk of memory safety bugs, data races and logic bugs overall," that "abstractions that are easier to reason about," and "More people get involved overall in developing the kernel, thanks to the usage of a modern language." Linus Torvalds responded in a new interview with IT Wire (shared by Slashdot reader juul_advocate): The first patches for Rust support in the Linux kernel have been posted and the man behind the kernel says the fact that these are being discussed is much more important than a long post by Google about the language. Linus Torvalds told iTWire in response to queries that Rust support was "not there yet", adding that things were "getting to the point where maybe it might be mergeable for 5.14 or something like that..." Torvalds said that it was still early days for Rust support, "but at least it's in a 'this kind of works, there's an example, we can build on it'." Asked about a suggestion by a commenter on the Linux Weekly News website, who said, during a discussion on the Google post, "The solution here is simple: just use C++ instead of Rust", Torvalds could not restrain himself from chortling. "LOL," was his response. "C++ solves _none_ of the C issues, and only makes things worse. It really is a crap language. "For people who don't like C, go to a language that actually offers you something worthwhile. Like languages with memory safety and [which] can avoid some of the dangers of C, or languages that have internal GC [garbage collection] support and make memory management easier. C++ solves all the wrong problems, and anybody who says 'rewrite the kernel in C++' is too ignorant to even know that." He said that when one spoke of the dangers of C, one was also speaking about part of what made C so powerful, "and allows you to implement all those low-level things efficiently". Torvalds added that, while garbage collection is "a very good thing in most other situations," it's "generally not necessarily something you can do in a low-level system programming."' -- source: https://developers.slashdot.org/story/21/04/17/009241 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/

Happy 50th Birthday FTP

by Peter Reutemann

'FTP (file transfer protocol) celebrated its 50th anniversary this week. Long-time Slashdot reader sandbagger shares an article commemorating a half-century of FTP: Over the years, the FTP protocol got refined with 16 different revisions(*1) adding support with TCP/IP, a secure extension also known as FTPS which is leveraging the same tech as HTTPS and more recent addition like IPv6 support. Fifty years after its inception, FTP is still going very strong with millions of FTP server still being exposed on the internet which is fairly amazing considering the bad press it gets...

Slackware Approaches 28th Birthday With New Beta Release

by Peter Reutemann

'Slashdot reader LeeLynx shares news from The Register about a Slackware 15 beta release (following the debut of February's alpha), "nearly five years after the distribution last saw a major update." (And nearly 28 years after its initial release back in 1993...) Created by Patrick Volkerding (who still lays claim to the title Benevolent Dictator For Life), the current release version arrived in the form of 2016's 14.2... The Linux kernel has been updated to 5.10.30 (at time of writing) with 5.11.14 available for testing. Desktop fans may be pleased to see, among the many updates, KDE Plasma hitting 5.21.4 as well as updates for old faithfuls, such as Mozilla Firefox and Thunderbird. The beta itself dropped on 12 April (with the 5.10.29 kernel) and Volkerding noted: "I'm going to go ahead and call this a beta even though there's still no fix for the illegal instruction issue with 32-bit mariadb. But there should be soon." Tinkering has continued since, judging by the change log, although the beta tag brings hope there will be a release before long.' -- source: https://linux.slashdot.org/story/21/04/18/007214 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/

China and Huawei's Dystopian 'New IP' Plan for 6G

by Peter Reutemann

'Just Security: Huawei's plans for 6G and beyond make U.S. concerns over 5G look paltry: Huawei is proposing a fundamental internet redesign, which it calls "New IP," designed to build "intrinsic security" into the web. Intrinsic security means that individuals must register to use the internet, and authorities can shut off an individual user's internet access at any time. In short, Huawei is looking to integrate China's "social credit," surveillance, and censorship regimes into the internet's architecture... To avoid scrutiny of New IP's shortcomings, Huawei has circumvented international standards bodies where experts might challenge the technical shortcomings of the proposal. Instead, Huawei has worked through the United Nations' International Telecommunications Union (ITU), where Beijing holds more political sway... Huawei dominance on New IP and 6G would not only create a less free, less interoperable internet, it would pave the way for authoritarian governments to gain expanded say over future changes to the internet for years to come.' -- source: https://tech.slashdot.org/story/21/04/17/2041239 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/

meeting next Monday

by Peter Reutemann

Hi everyone Due to ANZAC day being observed on Monday 26th, our next WLUG meeting is a week early on the 19th (ie next week!): 'Home automation (aka smart home) is now widely available through a range of consumer products. But often, these devices are only accessible through closed-source apps and also tend to "phone home". Let's have a look, together with Peter Reutemann, at Home Assistant (https://www.home-assistant.io/), an open-source home automation framework that puts local control and privacy first.' -- source: https://www.meetup.com/WaikatoLinuxUsersGroup/events/274861049/ 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/

FreeBSD 13 Released

by Peter Reutemann

'"FreeBSD, the other Linux, reached version 13," writes long-time Slashdot reader undoman. "The operating system is known for its stable code, native ZFS support, and use of the more liberal BSD licenses." Phoronix highlights some of the major new improvements: FreeBSD 13.0 delivers on performance improvements (particularly for Intel CPUs we've seen in benchmarks thanks to hardware P-States), upgrading to LLVM Clang 11 as the default compiler toolchain, POWER 64-bit support improvements, a wide variety of networking improvements, 64-bit ARM (AArch64) now being a tier-one architecture alongside x86_64, EFI boot improvements, AES-NI is now included by default for generic kernel builds, the default CPU support for i386 is bumped to i686 from i486, and a variety of other hardware support improvements. Various obsolete GNU tools have been removed like an old version of GNU Debugger used for crashinfo, obsolete GCC 4.2.1 and Binutils 2.17 were dropped from the main tree, and also switching to a BSD version of grep.

EFF Partners With DuckDuckGo

by Peter Reutemann

'The Electronic Frontier Foundation (EFF) today announced it has enhanced its groundbreaking HTTPS Everywhere browser extension by incorporating rulesets from DuckDuckGo Smarter Encryption. According to the digital rights group's press release, HTTPS Everywhere is "a collaboration with The Tor Project and a key component of EFF's effort to encrypt the web and make the Internet ecosystem safe for users and website owners." From the press release: "DuckDuckGo Smarter Encryption has a list of millions of HTTPS-encrypted websites, generated by continually crawling the web instead of through crowdsourcing, which will give HTTPS Everywhere users more coverage for secure browsing," said Alexis Hancock, EFF Director of Engineering and manager of HTTPS Everywhere and Certbot web encrypting projects. "We're thrilled to be partnering with DuckDuckGo as we see HTTPS become the default protocol on the net and contemplate HTTPS Everywhere's future." EFF began building and maintaining a crowd-sourced list of encrypted HTTPS versions of websites for a free browser extension -- HTTPS Everywhere -- which automatically takes users to them. That keeps users' web searching, pages visited, and other private information encrypted and safe from trackers and data thieves that try to intercept and steal personal information in transit from their browser. [...] DuckDuckGo, a privacy-focused search engine, also joined the effort with Smarter Encryption to help users browse securely by detecting unencrypted, non-secure HTTP connections to websites and automatically upgrading them to encrypted connections. With more domain coverage in Smarter Encryption, HTTPS Everywhere users are provided even more protection. HTTPS Everywhere rulesets will continue to be hosted through this year, giving our partners who use them time to adjust. We will stop taking new requests for domains to be added at the end of May.
