Weta Digital’s Technology Division Sold To US Firm
by Lawrence D'Oliveiro 01 Aug '25

01 Aug '25

Let me see if I understand this article <https://www.nzherald.co.nz/business/sir-peter-jackson-to-sell-weta-digital-…> correctly: the part of Weta Digital that used to develop the in-house 3D graphics/effects tools that they use in all those movies is being sold to US-based Unity Software. The part that is left will be called “WetaFX”, and will become a customer of Unity for the use of those tools, no longer doing its own development in-house. By the way, I’ve been looking at the Unity site <https://unity.com/>, and it looks like all their products are rentware (subscription-based).

Debian isn't waiting for 2038 to blow up, switches to 64-bit time for everything
by Peter Reutemann 31 Jul '25

31 Jul '25

'Venerable Linux distribution Debian is side-stepping the Y2K38 bug – also known as the Unix Epochalypse – by switching to 64-bit time for everything but the oldest of supported hardware, starting with the upcoming Debian 13 "Trixie" release. "[We will] use 64-bit time_t on 32-bit architectures to avoid the 'year 2038 problem' when the existing 32-bit signed int rolls over (potentially setting time back to 1900)," the Debian maintainers say of the move and the problem it aims to fix. y2k illustration retro futuristic The 'nothing-happened' Y2K bug – how the IT industry worked overtime to save world's computers READ MORE "This is now less than 15 years away and plenty of systems that will have problems have already been shipped. We should stop adding to the problem." Readers of a certain vintage will remember well the "Y2K problem," caused by retrospectively shortsighted attempts to save a couple of bytes by using two-digit years – meaning that "2000" is represented as "00" and assumed to be "1900." While predictions of aircraft falling from the skies and bank balances being wiped out by negative-decades of interest did not, thankfully, come true, that was purely due to the tireless behind-the-scenes work of software developers who were able to patch affected systems before celebrating the turn of the century. There's another, less well-known clock problem looming, however: the Unix Epochalypse,which affects any systems that measure time the Unix way – in seconds elapsed since January 1, 1970. Come the very precise time of 03:14:07 UTC on January 19, 2038, the number of seconds elapsed will be larger than can be represented by a signed 32-bit integer. This would be fine if the decision hadn't been made all those years ago to store the number of seconds in exactly such a format.' -- source: https://www.theregister.com/2025/07/25/y2k38_bug_debian/ Cheers, Peter

Malware Discovered in Arch Linux AUR Packages
by Peter Reutemann 28 Jul '25

28 Jul '25

Something for the arch users on here: 'If you are an Arch user, you know – AUR (Arch User Repository) is a double-edged sword—it’s incredibly useful but requires caution. Unfortunately, that caution was warranted yet again this week when three AUR packages were found to contain malware. The issue came to light on July 16 when a user uploaded a malicious package, librewolf-fix-bin, to the AUR. Within hours, two more packages—firefox-patch-bin and zen-browser-patched-bin—followed, all traced back to the same bad actor. Security researchers quickly identified the threat: a Remote Access Trojan (RAT) hidden in a script pulled from a GitHub repository. For those unfamiliar, a RAT is no joke—it can grant attackers full control over an infected system, enabling them to steal data, install additional malware, or spy on users. Thankfully, the Arch Linux security team responded promptly as soon as they became aware of the issue. By July 18, all three malicious packages had been removed from AUR.' -- source: https://linuxiac.com/malware-discovered-in-arch-linux-aur-packages/ Cheers, Peter

Clear Linux Discontinued as Intel Pulls the Plug Overnight
by Peter Reutemann 28 Jul '25

28 Jul '25

'Unfortunately, there’s a bit of sad news out of the Linux world this week, with Clear Linux taking center stage. What I’m talking about is that Intel has formally ended support for Clear Linux OS, drawing a rapid close to a nearly decade-long effort to showcase aggressive, upstream-friendly performance optimizations on x86_64. In a blog post titled “All good things come to an end: Shutting down Clear Linux OS,” the announcement states that support ends immediately, with no trailing window for security updates. "After years of innovation and community collaboration, we’re ending support for Clear Linux OS. Effective immediately, Intel will no longer provide security patches, updates, or maintenance for Clear Linux OS, and the Clear Linux OS GitHub repository will be archived in read-only mode." Crucially, “effective immediately” is not rhetorical: Intel states that there will be no further security patches, updates, or maintenance, and the project’s GitHub repository is to be archived in a read-only manner. As you can guess, that abrupt cutoff leaves any production or lab systems running Clear Linux exposed going forward, so administrators now face an urgent migration. For those unfamiliar, Clear Linux (a project launched in 2015) is an open-source, rolling-release Linux distribution developed by Intel’s Open Source Technology Center, purpose-built to showcase and leverage Intel’s hardware strengths, with a focus on high performance, security, and cloud-native workloads. -- source: https://linuxiac.com/intel-shuts-down-clear-linux-os/ Cheers, Peter

Let Sudo Insult You When You Enter Incorrect Password
by Peter Reutemann 24 Jul '25

24 Jul '25

Add some spice to your incorrect password attempts! :-) 'Sudoers is the default sudo security policy plugin in Linux; however, experienced system administrators can specify a custom security policy as well as input and output logging plugins. It is driven by the /etc/sudoers file or, alternatively by LDAP. You can define sudoers options like the insults option or several others in the file /etc/sudoers. It is set under the Defaults entries section. [...] In this article, we will explain a sudoers configuration parameter to enable an individual or system administrator to set sudo command to insult system users who enter the wrong password.' -- source: https://www.tecmint.com/sudo-insult-when-enter-wrong-password/ Cheers, Peter

23 Jul '25

Just came across FossFLOW: 'FossFLOW is a powerful, open-source Progressive Web App (PWA) for creating beautiful isometric diagrams. Built with React and the Isoflow (Now forked and published to NPM as fossflow) library, it runs entirely in your browser with offline support.' You can try it out here: https://stan-smith.github.io/FossFLOW/ Maybe something to consider next time you create a diagram? :-) -- code: https://github.com/stan-smith/FossFLOW -- source: https://mastodon.social/@nixCraft/114897260096883374 Cheers, Peter

Microsoft's Secure Boot UEFI Bootloader Signing Key Expires In September, Posing Problems For Linux Users
by Lawrence D'Oliveiro 23 Jul '25

23 Jul '25

If I understand this article right <https://www.tomshardware.com/tech-industry/cyber-security/microsoft-signing…>, there is a signing key stored in the flash RAM of PCs, issued by Microsoft, which is used to sign a “shim” that allows third-party Linux distros to boot. However, that key is due to expire this September. Microsoft issued an updated key two years ago, but that key may not be widely installed as yet. This leaves it up to PC/OEM vendors to issue updates to the flash RAM on their motherboards, which is not something that can be taken for granted. I’m not the only one wondering whether Secure Boot is worth the hassle: It's easy to see the appeal of Secure Boot—making it more difficult to install bootkits should be a net positive. However, the looming hassle of dealing with this expiring key is just the latest in a series of frustrations that encourage people to either stick with Windows or disable Secure Boot entirely. Right now, many people opt for the former, but will that continue to be the case as the popularity of other platforms rises ahead of Windows 10's demise? And is Secure Boot, as it currently exists, prepared for that shift?

Actively exploited vulnerability gives extraordinary control over server fleets
by Peter Reutemann 21 Jul '25

21 Jul '25

'Hackers are exploiting a maximum-severity vulnerability that has the potential to give them complete control over thousands of servers, many of which handle mission-critical tasks inside data centers, the US Cybersecurity and Infrastructure Security Agency is warning. The vulnerability, carrying a severity rating of 10 out of a possible 10, resides in the AMI MegaRAC, a widely used firmware package that allows large fleets of servers to be remotely accessed and managed even when power is unavailable or the operating system isn't functioning. These motherboard-attached microcontrollers, known as baseboard management controllers (BMCs), give extraordinary control over servers inside data centers. Administrators use BMCs to reinstall operating systems, install or modify apps, and make configuration changes to large numbers of servers without physically being on premises and, in many cases, without the servers being turned on. Successful compromise of a single BMC can be used to pivot into internal networks and compromise all other BMCs. CVE-2024-54085, as the vulnerability is tracked, allows for authentication bypasses by making a simple web request to a vulnerable BMC device over HTTP. The vulnerability was discovered by security firm Eclypsium and disclosed in March. The disclosure included proof-of-concept exploit code allowing a remote attacker to create an admin account without providing any authentication. At the time of the disclosure, there were no known reports of the vulnerability being actively exploited. On Wednesday, CISA added CVE-2024-54085 to its list of vulnerabilities known to be exploited in the wild. The notice provided no further details.' -- source: https://arstechnica.com/security/2025/06/active-exploitation-of-ami-managem… Cheers, Peter
