BrianFagioli writes: Fedora Linux 43 users upgrading to the latest Dovecot mail server discovered something rather unsettling: some older Microsoft Outlook configurations may have been silently ignoring SSL/TLS settings for POP3 email connections for years. According to a Fedora community blog post, affected Outlook clients reportedly continued using insecure port 110 connections even when encryption was enabled in the application settings. The issue surfaced after Dovecot 2.4 disabled plaintext authentication on non secure connections by default, causing Outlook users to suddenly lose mailbox access after the Fedora 43 upgrade. The report suggests the behavior may date back as far as Outlook 2007, although modern Outlook builds were not fully tested. Fedora admins stress that the problem could be limited to legacy account configurations rather than current versions of Outlook itself. Still, the discovery has sparked discussion among Linux admins and security folks because many users likely assumed their email traffic was encrypted simply because Outlook claimed SSL/TLS was enabled. The incident also highlights how stricter defaults in modern open source infrastructure can expose ancient assumptions and questionable behaviors that quietly survived for decades.

At its Build conference, Microsoft announced coreutils for Windows. Coreutils for Windows is a Microsoft-maintained set of UNIX-style command-line utilities that run natively on Windows - the same commands and pipelines you use on Linux, macOS, and WSL. It ships as a single multi-call binary that exposes each utility under its standard name (cat.exe, grep.exe, find.exe, and so on), giving you the everyday tools developers already use on other platforms to script, automate, and process text. For the full list, see Commands. The goal is to remove friction when moving between Linux, macOS, WSL, containers, and Windows. The same commands, flags, and pipelines work the same way, so existing scripts and habits carry over without translation. Each command supports the standard --help flag for full syntax and options. ↫ Windows Developer Tools website It's a port of the Rust-based rewrite of the GNU coreutils, findutils, and grep. There are a few caveats though, since these ports have to deal with a number of Windows-isms. The first thing that comes to mind for most of us are path separators; these ports will handle both the correct and incorrect Windows/DOS one, but since some tools may output only the incorrect one this may affect piping. You should also take into account things like Windows' ACLs vs. POSIX permission bits, the lack of /dev/null, and a few other oddities. Furthermore, there are a bunch of commands that rely on POSIX-only concepts, so those aren't included, and a few other commands that aren't useful on Windows are excluded as well. Since a number of commands conflict with built-in commands from cmd.exe and PowerShell, which commands run will depend on the shell, the PATH order, and PowerShell's alias table. Everything's in preview, and installable through WinGet.

Ancient Slashdot reader whitroth shares a report from Politico, with the caption: "shutting down Microsoft Office for the International Criminal Court (ICC) was clearly a wake-up call." From the report: The EU is moving to counter American dominance in technology by reaching for one of the oldest tools in its arsenal: industrial strategy. As the European Commission unveiled a plan Wednesday to reduce Europe's reliance on the foreign technology providers that underpin the modern economy, it was careful to stress that it was not picking a fight with U.S. digital giants. Instead, the tech sovereignty package -- motivated in no small part by U.S. President Donald Trump's weaponization of Europe's dependence on American firms -- takes a longer-term view: boost the continent's players so they can eventually challenge their U.S. rivals. [...] If adopted, the package will direct public money toward products that contribute to Europe's economy and independence from foreign firms; cut red tape for data centers; beef up research and innovation through "leadership initiatives"; incentivize countries to share digital capacities in a new "Eurocloud" forum; and require EU governments to come up with national strategies to boost the adoption of cutting-edge tech, including AI. The package will also seek to ramp up the bloc's demand for advanced chips -- a response to criticism by the industry -- with a series of industrial initiatives to revise a 2023 chips law. [...] As part of its proposal to keep a list of trustworthy countries, the Commission would require EU governments to run a so-called "sovereignty risk assessment" for every digital service they rely on, measuring foreign control, potential access to sensitive data and the risk of operational disruption. Within a year, they would have to determine the appropriate level of protection for each public sector and procure digital services accordingly -- unless they can prove doing so would come at a "disproportionate cost," the proposal reads. However, the Commission reserves the right to overrule their assessment in future legislation if it believes they downplayed the risks. The Commission estimated that just one percent of Europe's public services are so sensitive that they would be required under the proposed certification scheme to rely on the strict level that totally excludes foreign technology. "We cannot afford to depend on others for the technologies that keep our hospitals running, our energy grids stable and our services secure," Commission President Ursula von der Leyen said in a statement. "This is about protecting our citizens, defending our interests and making our own choices."

On the Vogon forums, user MarkDastedt posted an interesting bit of source code he discovered on an old company DVD: a very basic, very rudimentary implementation of multicore support for DOS. Another user, dartfrog, took a closer look and had this to say: Interesting stuff nonetheless. A worker core is running with no interrupt handlers, no page tables, no memory protection, and no OS. That's about as close to bare metal as you can get, meanwhile the other core is still running DOS. Fascinating. ↫ MarkDastedt at the Vogon forums It's effectively a simple demo, but according to other users in the thread, it fits in neatly with sporadic other attempts to bring some form of SMP or multicore-awareness to DOS. For instance, Michael Chourdakis worked on something similar to this demo for a series of articles now only available on the Wayback Machine. It makes for a cool demo, but moving from this to something robust and usable in DOS is not an easy task. Still, the possibilities are definitely there, even if you don't implement full, modern SMP or multicore support. You could have specific DOS applications offloading dedicated tasks to different cores, but as others in the same thread note, individual cores are already stupidly powerful for anything DOS can do, making the use case for additional cores rather moot.

According to supply chain analyst Ming-Chi Kuo, Apple has reportedly doubled 2026 MacBook Neo production from 5 million to 10 million units after stronger-than-expected demand for its $599 budget laptop. MacRumors reports: On an earnings call in late April, Apple's CEO Tim Cook said that customer response to the MacBook Neo was "off the charts," and the popularity of the laptop has reportedly led the company to significantly boost production. [...] Apple was very optimistic about the MacBook Neo before announcing it, but the company still "undercalled" the level of enthusiasm that the laptop would generate, according to Cook. He said that MacBook Neo demand exceeded Apple's expectations and helped to drive a record number of first-time Mac buyers last quarter. New figures from market research firm IDC support Apple's claim that the MacBook Neo is selling well, and the Windows PC industry has taken notice. For example, Dell recently introduced a redesigned XPS 13 laptop from $699 and said it has features "you won't find on a MacBook Neo," such as a touch screen and a backlit keyboard. "Apple's MacBook Neo is a capable machine, and its arrival confirms that there's real appetite for premium quality at accessible prices," admitted Dell.

A hobby operating system, not written in Rust, not targeting Qemu, not targeting a Raspberry Pi. Yes, it still happens. Serena OS is what you get when modern operating system design and implementation meets vintage hardware like the Amiga computers. It is based on dispatch queues rather than threads, supports multiple users, is inspired by POSIX, yet retains its own character, is strongly object-oriented in terms of design and implementation and prepared for a cross platform future. ↫ Serena OS GitHub page Serena OS supports most (all?) of the classic Amigas, but the 500, 600, and 2000 need at least 1MB of RAM and a 68020 accelerator. It has code privilege separation between kernel and userspace, basic memory management, its own custom file system, drivers for input devices and graphics, an interactive console with VT52 and VT100 support, and much more. It also comes with a C99-compatible libc, and has its own shell. Note that "AI" chatbot Claude is listed as a contributor to the project.
