Mozilla Names New CEO as It Pivots To Data Privacy
by Peter Reutemann 09 Feb '24

09 Feb '24

'Mozilla, which manages the open-source Firefox browser, announced today that Mitchell Baker is stepping down as CEO to focus on AI and internet safety as chair of the nonprofit foundation. Laura Chambers, a Mozilla board member and entrepreneur with experience at Airbnb, PayPal, and eBay, will step in as interim CEO to run operations until a permanent replacement is found. Fortune: Baker, a Silicon Valley pioneer who co-founded the Mozilla Project, says it was her decision to step down as CEO, adding that the move is motivated by a sense of urgency over the current state of the internet and public trust. "We want to offer an alternative for people to have better products," says Baker, who wants to draw more attention to policies, products and processes to challenge business models built on fueling outrage. "What are the connections between this global malaise and how humans are engaging with each other and technology?" Chambers says she plans to focus on building out new products that address growing privacy concerns while actively looking for a full-time CEO. Prior to being recruited to the Mozilla board three years ago, Chambers says she was feeling "pretty disillusioned" about society because of the influence of money in politics and the growing power of the tech giants. "I was confused about what to do and this felt like a genuine way to make an impact." Chambers says she won't be seeking a permanent CEO role because she plans to move back to Australia later this year for family reasons. "I think this is an example of Mozilla doing the right role modelling in how to manage a succession," says Chambers.

Critical Vulnerability Affecting Most Linux Distros Allows For Bootkits
by Peter Reutemann 08 Feb '24

08 Feb '24

'Linux developers are in the process of patching a high-severity vulnerability that, in certain cases, allows the installation of malware that runs at the firmware level, giving infections access to the deepest parts of a device where they're hard to detect or remove. ArsTechnica: The vulnerability resides in shim, which in the context of Linux is a small component that runs in the firmware early in the boot process before the operating system has started. More specifically, the shim accompanying virtually all Linux distributions plays a crucial role in secure boot, a protection built into most modern computing devices to ensure every link in the boot process comes from a verified, trusted supplier. Successful exploitation of the vulnerability allows attackers to neutralize this mechanism by executing malicious firmware at the earliest stages of the boot process before the Unified Extensible Firmware Interface firmware has loaded and handed off control to the operating system. The vulnerability, tracked as CVE-2023-40547, is what's known as a buffer overflow, a coding bug that allows attackers to execute code of their choice. It resides in a part of the shim that processes booting up from a central server on a network using the same HTTP that the the web is based on. Attackers can exploit the code-execution vulnerability in various scenarios, virtually all following some form of successful compromise of either the targeted device or the server or network the device boots from. "An attacker would need to be able to coerce a system into booting from HTTP if it's not already doing so, and either be in a position to run the HTTP server in question or MITM traffic to it," Matthew Garrett, a security developer and one of the original shim authors, wrote in an online interview. "An attacker (physically present or who has already compromised root on the system) could use this to subvert secure boot (add a new boot entry to a server they control, compromise shim, execute arbitrary code)."' -- source: https://linux.slashdot.org/story/24/02/07/1749248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Overzealous Spam Filters
by Lawrence D'Oliveiro 07 Feb '24

07 Feb '24

Two recent news items about important messages being lost in the recipients’ spam filters. Some months ago, the Banking Ombudsman sent out a warning about investment scams to various financial institutions, but the ANZ never saw theirs <https://www.nzherald.co.nz/nz/anz-misses-investment-scam-warning-from-banki…>. One scam victim believes that her case might have been caught sooner if the bank had taken suitable notice of such a warning. And a US-based team wanted to join Formula 1, but it seems they never got the invitation to meet in person to discuss their application, because it got classed as spam <https://arstechnica.com/cars/2024/02/a-spam-folder-may-have-foiled-andretti…>. And so their application was rejected. But then, in this case you’d think more than one attempt would have been made to get in touch. In both cases, the sender address would have been something unusual, not the kind of thing you or I might see in our in-box (in one case, the Banking Ombudsman, in the other case, the Formula 1 rights body). If we got such a message, it would be wise to score it as being more likely to be some sort of scam. But for organizations that work in those areas that are more likely to engage in such communications, it would make sense to customize their spam filters in the opposite direction, don’t you think?

Enabling Case-Insensitive Filenames On Linux
by Lawrence D'Oliveiro 06 Feb '24

06 Feb '24

The ext4 filesystem has had the “casefold” option for a while now <https://lwn.net/Articles/784041/>. This allows you to specify, when you initialize a new filesystem, that you want file/directory names to be treated as case-insensitive. At the same time, you have to specify that the filenames are to be interpreted as UTF-8 encoding; normally the kernel doesn’t care, it only singles out ASCII slash and NUL bytes for special interpretation, and simply passes through any other byte values in the names. I was able to create such a filesystem, but I wasn’t able to mount it in my last-upgraded-just-a-few-days-ago Debian Unstable setup. When I try, it fails, and in the dmesg log I see Filesystem with casefold feature cannot be mounted without CONFIG_UNICODE Turns out the Debian 5.10 kernel has not been built with this CONFIG_UNICODE option enabled. However, this situation looks set to change shortly, according to <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985689>.

Hi everyone Just came across browsh: 'A fully interactive, real-time, and modern text-based browser rendered to TTYs and browsers' https://github.com/browsh-org/browsh Seems like a cool way of browsing in the shell. I've used lynx in the past for that.

How a Microsoft Update Broke VS Code Editor on Ubuntu
by Peter Reutemann 05 Feb '24

05 Feb '24

'Microsoft's Visual Studio Code editor now includes a voice command that launches GitHub Copilot Chat just by saying "Hey Code." But one Linux blog notes that the editor has suddenly stopped supporting Ubuntu 18.04 LTS — "a move causing issues for scores of developers." VS Code 1.86 (aka the 'January 2024' update) saw Microsoft bump the minimum build requirements for the text editor's popular remote dev tools to â¥glibc 2.28 — but Ubuntu 18.04 LTS uses glibc 2.27, ergo they no longer work. While Ubuntu 18.04 is supported by Canonical until 2028 (through ESM) a major glibc upgrade is unlikely. Thus, this "breaking change" is truly breaking workflows... It seems affected developers were caught off-guard as this (rather impactful) change was not signposted before, during, or after the VS Code update (which is installed automatically for most, and the update was pushed out to Ubuntu 18.04 machines). Indeed, most only discovered this issue after update was installed, they tried to connect to a remote server, and discovered it failed. The resulting error message does mention deprecation and links to an FAQ on the VS Code website with workarounds (i.e. downgrade). But as one developer politely put it.... "It could have checked the libc versions and refused the update. Now, many people are screwed in the middle of their work." The article points out an upgrade to Ubuntu 20.04 LTS will address the problem. On GitHub a Microsoft engineer posted additional options from VS Code's documentation: If you are unable to upgrade your Linux distribution, the recommended alternative is to use our web client. If you would like to use the desktop version, then you can download the VS Code release 1.85. Depending on your platform, make sure to disable updates to stay on that version. Microsoft then locked the thread on GitHub as "too heated" and limited conversation to just collaborators. In a related thread someone suggested installing VS Code's Flatpak, which was still on version 1.85 — and then disabling updates. But soon Microsoft had locked that thread as well as "too heated," again limiting conversation to collaborators.' -- source: https://linux.slashdot.org/story/24/02/04/0116229 When you can't take criticism for a balls-up, lock the discussion thread!

LibreOffice 24.2 Delivers Advanced Features and Global Accessibility
by Peter Reutemann 02 Feb '24

02 Feb '24

'The Document Foundation has officially launched LibreOffice 24.2, which is now available for download for Windows, macOS, and Linux platforms. This release introduces a new calendar-based version numbering system (YY.M). Here’s what it’s all about. The latest major release of the well-known office suite was 7.6. However, this is set to change with the introduction of 24.2, as the version numbering will now follow a “year.month” pattern, similar to that used by Ubuntu releases, for example. This change aims to simplify version identification for end users, making it more intuitive to understand.' -- source: https://linuxiac.com/libreoffice-24-2-delivers-advanced-features-and-global… ...and here I was, thinking that I missed a truckload of releases. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Microsoft Stole My Chrome Tabs, and It Wants Yours, Too'
by Peter Reutemann 31 Jan '24

31 Jan '24

'Tom Warren, writing for The Verge: Last week, I turned on my PC, installed a Windows update, and rebooted to find Microsoft Edge automatically open with the Chrome tabs I was working on before the update. I don't use Microsoft Edge regularly, and I have Google Chrome set as my default browser. Bleary-eyed at 9AM, it took me a moment to realize that Microsoft Edge had simply taken over where I'd left off in Chrome. I never imported my data into Microsoft Edge, nor did I confirm whether I wanted to import my tabs. But here was Edge automatically opening after a Windows update with all the Chrome tabs I'd been working on. I didn't even realize I was using Edge at first, and I was confused why all my tabs were suddenly logged out. After the shock wore off, I looked to make sure I hadn't accidentally allowed this behavior. I found a setting in Microsoft Edge that imports data from Google Chrome on each launch. "Always have access to your recent browsing data each time you browse on Microsoft Edge," reads Microsoft's description of the feature in Edge. This setting was disabled, and I had never been asked to turn it on. So I went to install the same Windows update on a laptop, which actually resulted in it failing and my having to do a system restore. Once the system restore was complete, the same thing happened. Edge opened automatically with all of my Chrome tabs. I haven't been able to replicate the behavior on other PCs, but a number of X users replied to my post about this saying they have experienced the same thing in the past.' -- source: https://it.slashdot.org/story/24/01/30/1824233 Cheers, peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi Is Planning a London IPO, But Its CEO Expects 'No Change' In Focus
by Peter Reutemann 31 Jan '24

31 Jan '24

'Ars Technica: The business arm of Raspberry Pi is preparing to make an initial public offering (IPO) in London. CEO Eben Upton tells Ars that should the IPO happen, it will let Raspberry Pi's not-for-profit side expand by "at least a factor of 2X." And while it's "an understandable thing" that Raspberry Pi enthusiasts could be concerned, "while I'm involved in running the thing, I don't expect people to see any change in how we do things." CEO Eben Upton confirmed in an interview with Bloomberg News that Raspberry Pi had appointed bankers at London firms Peel Hunt and Jefferies to prepare for "when the IPO market reopens." Raspberry previously raised money from Sony and semiconductor and software design firm ARM, and it sought public investment. Upton denied or didn't quite deny IPO rumors in 2021, and Bloomberg reported Raspberry Pi was considering an IPO in early 2022. After ARM took a minority stake in the company in November 2023, Raspberry Pi was valued at roughly 400 million pounds, or just over $500 million. Given the company's gradual recovery from pandemic supply chain shortages, and the success of the Raspberry Pi 5 launch, the company's IPO will likely jump above that level, even with a listing in the UK rather than the more typical US IPO. Upton told The Register that "the business is in a much better place than it was last time we looked at it [an IPO]. We partly stopped because the markets got bad. And we partly stopped because our business became unpredictable." "It's a good thing, in that people care about us," Upton said in response to concerned hobbyists and tech enthusiasts. "What Raspberry Pi [builds] are the products we want to buy, and then we sell them to people like us," Upton said. "Certainly, while I'm involved in it, I can't imagine an environment in which the hobbyists are not going to be incredibly important." The IPO is "about the foundation," Upton said, with that charitable arm selling some of its majority stake in the business entity to raise funds and expand. "We've not cooked up some new way for a not-for-profit to do an IPO, no," he noted. [He told Ars that Raspberry Pi's business arm has had both strategic and private investors in its history, along with a majority shareholder in its Foundation (which in 2016 owned 75 percent of shares), and that he doesn't see changes to what Pi has built. He also noted that the foundation was previously funded by dividends from the business side.] "We do this transaction, and the proceeds of that transaction allow the foundation to train teachers, run clubs, expand programs, and ... do those things at, at least, a factor of 2X. That's what I'm most excited about." Upton said there would be "no change" to the kinds of products Pi makes, and that makers are "culturally important to us." [...] "If people think that an IPO means we're going to ... push prices up, push the margins up, push down the feature sets, the only answer we can give is, watch us. Keep watching," he said. "Let's look at it in 15, 20 years' time."' -- source: https://hardware.slashdot.org/story/24/01/30/2212232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux On Mars: The Final Chapter
by Lawrence D'Oliveiro 30 Jan '24

30 Jan '24

You may have heard that the “Ingenuity” helicopter, which has been flying on Mars for the last three years, came a cropper and broke one of its rotor blades a couple of weeks ago. Not bad for a project that was really put together as an afterthought, a proof of concept that was planned to maybe last 30 days and make five flights at most. Here <https://arstechnica.com/space/2024/01/now-that-weve-flown-on-mars-what-come…> is a description of some more details of how it was put together, within stringent limits on both mass and money. Apparently, a radiation-hardened RAD750 computer, which is normally used for such space missions, costs a quarter of a million USD. And would have weighed too much anyway. So they used a cheap, lightweight Qualcomm chip instead, state of the art for smartphones of just a few years ago. And massively more powerful. And of course they ran off-the-shelf open-source software on it <https://www.jpl.nasa.gov/news/meet-the-open-source-software-powering-nasas-…>, <https://www.theverge.com/2021/2/19/22291324/linux-perseverance-mars-curiosi…>, <https://spectrum.ieee.org/nasa-designed-perseverance-helicopter-rover-fly-a…>. Flying a chopper on Mars isn’t easy: the rotor tips on Ingenuity were moving at Mach 0.65 (on Mars, Mach 1.0, the speed of sound, is about 240m/s). A future chopper is planned to push this to Mach 0.95. You might say they were cutting corners on this design, which made it inherently more risky. But if the lower costs and simpler development can lead to shorter lead times, and hence more missions, maybe a higher failure rate would be worth it.
