Bell Labs "created many of the foundational innovations of the modern age," writes Jon Gertner, author of The Idea Factory: Bell Labs and the Great Age of American Innovation — from transistors and telecommunications satellites to Unix and the C programming language.

But what was the secret to its success? he asks in a new article for the Wall Street Journal. Start with its lucky arrival in a "problem-rich" environment, suggests Arno Penzias, winner of one of Bell Labs' 11 Nobel Prizes: It was Bell Labs' responsibility, in other words, to create technologies for designing, expanding and improving an unruly communications network of cables and microwave links and glass fibers. The Labs also had to figure out ways to create underwater conduits, as well as switching centers that could manage the growing number of customers and escalating amounts of data.... Money mattered, too. Being connected to AT&T, the largest company in the world, was an advantage. The Labs' budget was enormous, and accounting conventions allowed its parent company to make huge and continuing investments in R & D. The generous funding, moreover, allowed scientists and engineers to buy and build expensive equipment — for instance, anechoic chambers to create the world's quietest rooms...

The most fortunate part of Bell Labs' situation, however, was that in being attached to a monopoly it could partake in long-term thinking... Without competition nipping at its heels, Bell Labs engineers had the luxury of working out difficult ideas over decades. The first conceptualization of a cellular phone network, for instance, came out of the Labs in the late 1940s; it wasn't until the late 1970s that technicians began testing one in Chicago to gauge its potential. The challenge of deploying these technologies was immense. (The regulatory hurdles were formidable, too....)
The article also credits the visionary management of Mervin Kelly — who fortunately also "had access to funding in a decade when most executives and universities didn't" to hire the brightest people. (By the early 1980s Bell Labs employed about 25,000 researchers, technicians and support staff, with an annual budget of $2 billion — roughly $7 billion in today's dollars.) "The Labs' involvement in World War II suggested to Kelly that an exciting postwar era of electronics was approaching, but that the technical problems would be so complex that they required a mix of expertise — not just physicists, but material scientists, chemists, electrical engineers, circuitry experts and the like." At Bell Labs, Kelly would sometimes handpick teams and create such a mix, as was the case for the transistor invention in the late 1940s. He came to see innovation arising not from like-minded or similarly trained people conversing with each other, but from a friction of ideas and approaches. It meant hiring researchers who had different personalities and favored a range of experimental angles. It also meant personally designing a campus in Murray Hill where departments were spread apart, so that scientists and engineers would be forced to walk, mingle and engage in serendipitous conversations and debate ideas. Meanwhile, under Kelly, the Labs focused on hiring people who were deeply curious, not just smart. Kelly saw it as his professional duty to do far more than what was expected, with his laboratory and vast resources, to create new technologies...

The breakup of AT&T's monopoly, which led to a steady shrinking of Bell Labs' staff, budget and remit, shows us that no matter how forward looking your employees and managers may be, they will not necessarily see the future coming. It likewise suggests that technological progress is too unpredictable for one organization, no matter how powerful or smart, to control. Famously, Bell Labs managers didn't see value in the Arpanet, which eventually led to today's internet.

And yet, for at least five decades, Bell Labs created a blueprint for the global development of communications and electronics. In understanding why it did so, I tend to think its ultimate secret may be hiding in plain sight. The secret has to do with Bell Labs' structure — not only being connected to a fabulously profitable monopoly, but being connected to a company that could move theoretical and applied research into a huge manufacturing division that made telecom equipment (at Western Electric) and ultimately into a dynamic operating system (the AT&T network)... Scientists and engineers at the Labs understood their ideas would be implemented, if they passed muster, into the huge system its parent company was running.
Bell Labs racked up about 30,000 patents, according to the article, and celebrated its 100th anniversary last April.

It is now part of Finland-based Nokia.

Berlin-based T2 Linux developer René Rebe (long-time Slashdot reader ReneR) is announcing that their Xorg display server has now restored its XAA acceleration architecture, "bringing fixed-function hardware 2D acceleration back to many older graphics cards that upstream left in software-rendered mode." Older fixed-function GPUs now regain smooth window movement, low CPU usage, and proper 24-bit bpp framebuffer support (also restored in T2). Tested hardware includes ATi Mach-64 and Rage-128, SiS, Trident, Cirrus, Matrox (Millennium/G450), Permedia2, Tseng ET6000 and even the Sun Creator/Elite 3D.

The result: vintage and retro systems and classic high-end Unix workstations that are fast and responsive again.

Longtime Slashdot reader jrepin writes: KDE Plasma is a popular desktop (and mobile too) environment for GNU/Linux and other UNIX-like operating systems. Among other things, it also powers the desktop mode of the Steam Deck gaming handheld. The KDE community today announced the latest release: Plasma 6.6.

In this new major release, Spectacle can recognize texts from screenshots, a new on-screen keyboard and new login manager are available for testing, and a first-time wizard Plasma Setup was added. Your current theme can be saved as a new global theme, which can also be used for the day and night theme-switching feature. Emoji selector got a new easier way to select skin tone. If your computer has a camera available, you can now connect to a Wi-Fi network by scanning a QR code. Application sound volume can now be changed by scrolling over an application taskbar button via mouse wheel. When screencasting and sharing your desktop, you can now filter windows so they are not shared. A setting was added to enable having virtual desktops only on the primary screen. If your device has an ambient light sensor, you can enable automatic screen brightness adjustment. Game controllers can now be used as regular input devices.

For complete list of new features and changes, check out the KDE Plasma 6.6 release announcement and the complete changelog.

"More than two years after the last major 9.1 release, the Vim project has announced Vim 9.2," reports the blog Linuxiac: A big part of this update focuses on improving Vim9 Script as Vim 9.2 adds support for enums, generic functions, and tuple types.

On top of that, you can now use built-in functions as methods, and class handling includes features like protected constructors with _new(). The :defcompile command has also been improved to fully compile methods, which boosts performance and consistency in Vim9 scripts.

Insert mode completion now includes fuzzy matching, so you get more flexible suggestions without extra plugins. You can also complete words from registers using CTRL-X CTRL-R. New completeopt flags like nosort and nearest give you more control over how matches are shown. Vim 9.2 also makes diff mode better by improving how differences are lined up and shown, especially in complex cases.
Plus on Linux and Unix-like systems, Vim "now adheres to the XDG Base Directory Specification, using $HOME/.config/vim for user configuration," according to the release notes.

And Phoronix Mcites more new features: Vim 9.2 features "full support" for Wayland with its UI and clipboard handling. The Wayland support is considered experimental in this release but it should be in good shape overall...

Vim 9.2 also brings a new vertical tab panel alternative to the horizontal tab line.

The Microsoft Windows GUI for Vim now also has native dark mode support.
You can find the new release on Vim's "Download" page.

KDE's "Plasma Login Manager" is apparently dropping support for FreeBSD, the Unix-like operating system, reports the blog It's FOSS. They cite a recently-accepted merge request from a KDE engineer to drop the code supporting FreeBSD, since the login manager relies on systemd/logind: systemd and logind look like hard dependencies of the login manager, which means the software is built to work exclusively with these components and cannot function without them... logind is a component of systemd that is responsible for user session management...

This doesn't mean that KDE has abandoned the operating system altogether. FreeBSD users can still run the KDE Plasma desktop environment and continue using SDDM, the current login manager that works just fine on such systems.
The article argues FreeBSD users "won't really care much for missing out on this as they have plenty of login manager options available."

Jeffrey Snover, the driving force behind PowerShell, has retired after a career that reshaped Windows administration. The Register reports: Snover's retirement comes after a brief sojourn at Google as a Distinguished Engineer, following a lengthy stint at Microsoft, during which he pulled the company back from imposing a graphical user interface (GUI) on administrators who really just wanted a command line from which to run their scripts. Snover joined Microsoft as the 20th century drew to a close. The company was all about its Windows operating system and user interface in those days -- great for end users, but not so good for administrators managing fleets of servers. Snover correctly predicted a shift to server datacenters, which would require automated management. A powerful shell... a PowerShell, if you will.

[...] Over the years, Snover has dropped the occasional pearl of wisdom or shared memories from his time getting PowerShell off the ground. A recent favorite concerns the naming of Cmdlets and their original name in Monad: Function Units, or FUs. Snover wrote: "This abbreviation reflected the Unix smart-ass culture I was embracing at the time. Plus I was developing this in a hostile environment, and my sense of diplomacy was not yet fully operational." Snover doubtless has many more war stories to share. In the meantime, however, we wish him well. Many admins owe Snover thanks for persuading Microsoft that its GUI obsession did not translate to the datacenter, and for lengthy careers in gluing enterprise systems together with some scripted automation.

Remember that re-discovered computer tape with one of the earliest versions of Unix from the early 1970s? This week several local news outlets in Utah reported on the find, with KSL creating a video report with shots of the tape arriving at Silicon Valley's Computer History Museum, the closet where it was found, and even its handwritten label.

The Salt Lake Tribune reports that the closet where it was found also contained "old cords from unknown sources and mountains of papers that had been dumped from a former professor's file cabinet, including old drawings from his kids and saved plane ticket stubs." (Their report also includes a photo of the University of Utah team that found the tape — the University's Flux Research Group).

Professor Robert Ricci believes only 20 copies were ever produced of the version of Unix on that tape: At the time, in the 1970s, Ricci estimates there would have been maybe two or three of those computers — called a PDP-11, or programmed data processor — in Utah that could have run UNIX V4, including the one at the U. Having that technology is part of why he believes the U. got a copy of the rare software. The other part was the distinguished computing faculty at the school.

The new UNIX operating system would've been announced at conferences in the early 1970s, and a U. professor at the time named Martin Newell frequently attended those because of his own recognized work in the field, Ricci said. In another box, stuffed in under manila envelopes, [researcher Aleks] Maricq found a 1974 letter written to Newell from Ken Thompson at Bell Labs that said as soon as "a new batch comes from the printers, I will send you the system." Ricci and Maricq are unsure if the software was ever used. They reached out to Newell, who is now 72 and retired, as well as some of his former students. None of them recalled actually running it through the PDP-11...

The late Jay Lepreau also worked at the U.'s computing department and created the Flux Research Group that Ricci, Maricq and [engineering research associate Jon] Duerig are now part of. Lepreau overlapped just barely with Newell's tenure. In 1978, Lepreau and a team at the U. worked with a group at the University of California, Berkeley. Together, they built their own clone of the UNIX operating system. They called it BSD, or Berkeley Standard Distribution. Steve Jobs, the former CEO of Apple, worked with BSD, too, and it influenced his work.

Ultimately, it was Lepreau who saved the 9-track tape with the UNIX system on it in his U. office. And he's why the university still has it today. "He seems to have found it and decided it was worth keeping," Ricci said...

The U. will also get the tape back from the museum. Maricq said it will likely be displayed in the university's new engineering building that's set to open in January 2027. That's why, the research associate said, he was cleaning out the storage room to begin with — to try to prepare for the move. He was mostly just excited to see the floor again. "I thought we'd find some old stuff, but I didn't think it'd be anything like this," he said. And Maricq still has boxes to go through, including more believed to be from Lepreau's office.
Local news station KMYU captured the thoughts of some of the University researchers who found the tape: "When you see the very first beginnings of something, and you go from seed to sapling, that's what we saw here," [engineering research associate Jon] Duerig said. "We see this thing in the moment of flux. We see the signs of all the things changing — of all the things developing that we now see today."
Duerig also gave this comment to local news station KSL. "The coolest thing is that anybody, anywhere in the world can now access this, right? People can go on the internet archive and download the raw tape file and simulate running it," Duerig said. "People have posted browsable directory trees of the whole thing." One of the museum's directors said the tape's recovery marked a big day for the museum "One of the things that was pretty exciting to us is that just that there is this huge community of people around the world who were excited to jump on the opportunity to look at this piece of history," Ricci said. "And it was really cool that we were able to share that."

Duerig said while there weren't many comments or footnotes from the programmers of that time, they did discovery more unexpected content having to do with Bell Labs on the tape. "There were survey results of them actually asking survey questions of their employees at these operator centers," he said.

Wednesday marked the end of support for the last and final version of HP-UX, writes OSNews.

They call it "the end of another vestige of the heyday of the commercial UNIX variants, a reign ended by cheap x86 hardware and the increasing popularisation of Linux." I have two HP-UX 11i v1 PA-RISC workstations, one of them being my pride and joy: an HP c8000, the last and fastest PA-RISC workstation HP ever made, back in 2005. It's a behemoth of a machine with two dual-core PA-8900 processors running at 1Ghz, 8 GB of RAM, a FireGL X3 graphics card, and a few other fun upgrades like an internal LTO3 tape drive that I use for keeping a bootable recovery backup of the entire system. It runs HP-UX 11i v1, fully updated and patched as best one can do considering how many patches have either vanished from the web or have never "leaked" from HPE (most patches from 2009 onwards are not available anywhere without an expensive enterprise support contract)...

Over the past few years, I've been trying to get into contact with HPE about the state of HP-UX' patches, software, and drivers, which are slowly but surely disappearing from the web. A decent chunk is archived on various websites, but a lot of it isn't, which is a real shame. Most patches from 2009 onwards are unavailable, various software packages and programs for HP-UX are lost to time, HP-UX installation discs and ISOs later than 2006-2009 are not available anywhere, and everything that is available is only available via non-sanctioned means, if you know what I mean.

Sadly, I never managed to get into contact with anyone at HPE, and my concerns about HP-UX preservation seem to have fallen on deaf ears. With the end-of-life date now here, I'm deeply concerned even more will go missing, and the odds of making the already missing stuff available are only decreasing. I've come to accept that very few people seem to hold any love for or special attachment to HP-UX, and that very few people care as much about its preservation as I do. HP-UX doesn't carry the movie star status of IRIX, nor the benefits of being available as both open source and on commodity hardware as Solaris, so far fewer people have any experience with it or have developed a fondness for it.
As the clocks chimed midnight on New Year's Eve, he advised everyone to "spare a thought for the UNIX everyone forgot still exists."

Linux's share of the desktop market has climbed to as much as 11% by one count, but that figure includes Chromebooks, and the traditional Linux desktop remains hamstrung by the same fragmentation that killed Unix decades ago. Steven J. Vaughan-Nichols, writing in The Register, argues that the proliferation of Linux desktops -- more than a dozen significant interfaces exist today, and DistroWatch lists "upwards of a hundred" -- makes it nearly impossible for ordinary users to know where to start.

Linus Torvalds has long agreed with this hypothesis. "We have way too many desktops," Vaughan-Nichols notes, summarizing Torvalds' position. The deeper issue lies in software delivery: traditional package managers like DEB and RPM "simply don't scale for the desktop," forcing distro builders to constantly rebuild programs for their specific environments. Containerized solutions like Flatpaks, Snaps and AppImages should solve this by bundling dependencies into universal packages, but the Linux community remains divided over which to adopt.

Linux Mint, for instance, refuses Snap because "Canonical has too much control over the Snap store." Hardware support further complicates this challenges, the veteran journalist writes. While Dell sells Ubuntu machines and specialist vendors like System76 and TUXEDO Computers cater to enthusiasts, "none of them make it easy" for mainstream buyers, and no major OEM strongly backs Linux. Torvalds has pointed to Chromebooks and Android as the model: Linux won on smartphones because "there's a single, unified platform with a unified way to install programs."

Archive.org now has a page with "the raw analog waveform and the reconstructed digital tape image (analog.tap), read at the Computer History Museum's Shustek Research Archives on 19 December 2025 by Al Kossow using a modified tape reader and analyzed with Len Shustek's readtape tool." A Berlin-based retrocomputing enthusiast has created a page with the contents of the tape ready for bootstrapping, "including a tar file of the filesystem," and instructions on dumping an RK05 disk image from tape to disk (and what to do next).

Research professor Rob Ricci at the University of Utah's school of computing posted pictures and video of the tape-reading process, along with several updates. ("So far some of our folks think they have found Hunt The Wumpus and the C code for a Snobol interpreter.") University researcher Mike Hibler noted the code predates the famous comment "You are not expected to understand this" — and found part of the C compiler with a copyright of 1972.

The version of Unix recovered seems to have some (but not all) of the commands that later appeared in Unix v5, according to discussion on social media. "UNIX wasn't versioned as we know it today," explains University of Utah PhD student Thalia Archibald, who researched early Unix history (including the tape) and also worked on its upload. "In the early days, when you wanted to cut a tape, you'd ask Ken if it was a good day — whether the system was relatively bug-free — and copy off the research machine... I've been saying It's probably V5 minus a tiny bit, which turned out to be quite true."

FreeBSD 15.0-RELEASE arrived this week, notes this report from The Register, which calls it the latest release "of the Unix world's leading alternative to Linux." As well as numerous bug fixes and upgrades to many of its components, the major changes in this version are reductions in the number of platforms the OS supports, and in how it's built and how its component software is packaged.

FreeBSD 15 has significantly reduced support for 32-bit platforms. Compared to FreeBSD 14 in 2023, there are no longer builds for x86-32, POWER, or ARM-v6. As the release notes put it:

"The venerable 32-bit hardware platforms i386, armv6, and 32-bit powerpc have been retired. 32-bit application support lives on via the 32-bit compatibility mode in their respective 64-bit platforms. The armv7 platform remains as the last supported 32-bit platform. We thank them for their service."

Now FreeBSD supports five CPU architectures — two Tier-1 platforms, x86-64 and AArch64, and three Tier-2 platforms, armv7 and up, powerpc64le, and riscv64.

Arguably, it's time. AMD's first 64-bit chips started shipping 22 years ago. Intel launched the original x86 chip, the 8086 in 1978. These days, 64-bit is nearly as old as the entire Intel 80x86 platform was when the 64-bit versions first appeared. In comparison, a few months ago, Debian 13 also dropped its x86-32 edition — six years after Canonical launched its first x86-64-only distro, Ubuntu 19.10.

Another significant change is that this is the first version built under the new pkgbase system, although it's still experimental and optional for now. If you opt for a pkgbase installation, then the core OS itself is installed from multiple separate software packages, meaning that the whole system can be updated using the package manager. Over in the Linux world, this is the norm, but Linux is a very different beast... The plan is that by FreeBSD 16, scheduled for December 2027, the restructure will be complete, the old distribution sets will be removed, and the current freebsd-update command and its associated infrastructure can be turned off.

Another significant change is reproducible builds, a milestone the project reached in late October. This change is part of a multi-project initiative toward ensuring deterministic compilation: to be able to demonstrate that a certain set of source files and compilation directives is guaranteed to produce identical binaries, as a countermeasure against compromised code. A handy side-effect is that building the whole OS, including installation media images, no longer needs root access.

There are of course other new features. Lots of drivers and subsystems have been updated, and this release has better power management, including suspend and resume. There's improved wireless networking, with support for more Wi-Fi chipsets and faster wireless standards, plus updated graphics drivers... The release announcement calls out the inclusion of OpenZFS 2.4.0-rc4, OpenSSL 3.5.4, and OpenSSH 10.0 p2, and notes the inclusion of some new quantum-resistant encryption systems...

In general, we found FreeBSD 15 easier and less complicated to work with than either of the previous major releases. It should be easier on servers too. The new OCI container support in FreeBSD 14.2, which we wrote about a year ago, is more mature now. FreeBSD has its own version of Podman, and you can run Linux containers on FreeBSD. This means you can use Docker commands and tools, which are familiar to many more developers than FreeBSD's native Jail system.

"FreeBSD has its own place in servers and the public cloud, but it's getting easier to run it as a desktop OS as well," the article concludes. "It can run all the main Linux desktops, including GNOME on Wayland."

"There's no systemd here, and never will be — and no Flatpak or Snap either, for that matter.

"By my count, Linux has over 11% of the desktop market," writes ZDNet's Steven Vaughan-Nichols: In StatCounter's latest US numbers, which cover through October, Linux shows up as only 3.49%. But if you look closer, "unknown" accounts for 4.21%. Allow me to make an educated guess here: I suspect those unknown desktops are actually running Linux. What else could it be? FreeBSD? Unix? OS/2? Unlikely. In addition, ChromeOS comes in at 3.67%, which strikes me as much too low. Leaving that aside, ChromeOS is a Linux variant. It just uses the Chrome web browser for its interface rather than KDE Plasma, Cinnamon, or another Linux desktop environment. Put all these together, and you get a Linux desktop market share of 11.37%...

If you want to look at the broader world of end-user operating systems, including phones and tablets, Linux comes out even better. In the US, where we love our Apple iPhones, Android — yes, another Linux distro — boasts 41.71% of the market share, according to StatCounter's latest numbers. Globally, however, Android rules with 72.55% of the market. Yes, that's right, if you widen the Linux end-user operating system metric to include PC, tablets, and smartphones, you can make a reasonable argument that Linux, and not Windows, is already the top dog operating system...

If you add Chrome OS (1.7%) and Android (15.8%), 23.3% of all people accessing the U.S. government's websites are Linux users. The Linux kernel's user-facing footprint is much larger than the "desktop Linux" label suggests.
The article lists reasons more people might be switching to Linux, including broader hardware support and "the increased viability of gaming via Steam and Proton" — but also the rise of Digital Sovereignty initiatives. (One EU group has even created EU OS.")

And finally, "not everyone is thrilled with Windows 11 being turned into an AI-agentic operating system."

"PHP 8.5 landed on Thursday with a long-awaited pipe operator and a new standards-compliant URI parser," reports the Register, "marking one of the scripting language's more substantial updates... " The pipe operator allows function calls to be chained together, which avoids the extraneous variables and nested statements that might otherwise be involved. Pipes tend to make code more readable than other ways to implement serial operations. Anyone familiar with the Unix/Linux command line or programming languages like R, F#, Clojure, or Elixir may have used the pipe operator. In JavaScript, aka ECMAScript, a pipe operator has been proposed, though there are alternatives like method chaining.

Another significant addition is the URI extension, which allows developers to parse and modify URIs and URLs based on both the RFC 3986 and the WHATWG URL standards. Parsing with URIs and URLs â" reading them and breaking them down into their different parts â" is a rather common task for web-oriented applications. Yet prior versions of PHP didn't include a standards-compliant parser in the standard library. As noted by software developer Tim Düsterhus, the parse_url() function that dates back to PHP 4 doesn't follow any standard and comes with a warning that it should not be used with untrusted or malformed URLs.

Other noteworthy additions to the language include: Clone With, for updating properties more efficiently; the #[\NoDiscard] attribute, for warning when a return value goes unused; the ability to use static closures and first-class callables in constant expressions; and persistent cURL handles that can be shared across multiple PHP requests.

"A tape-based piece of unique Unix history may have been lying quietly in storage at the University of Utah for 50+ years," reports The Register. And the software librarian at Silicon Valley's Computer History Museum, Al Kossow of Bitsavers, believes the tape "has a pretty good chance of being recoverable." Long-time Slashdot reader bobdevine says the tape will be analyzed at the Computer History Museum. More from The Register: The news was posted to Mastodon by Professor Robert Ricci of the University of Utah's Kahlert School of Computing [along with a picture. "While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973..." Ricci posted on Mastodon. "We have arranged to deliver it to the Computer History Museum."] The nine-track tape reel bears a handwritten label reading: UNIX Original From Bell Labs V4 (See Manual for format)...

If it's what it says on the label, this is a notable discovery because little of UNIX V4 remains. That's unfortunate as this specific version is especially interesting: it's the first version of UNIX in which the kernel and some of the core utilities were rewritten in the new C programming language. Until now, the only surviving parts known were the source code to a slightly older version of the kernel and a few man pages — plus the Programmer's Manual [PDF], from November 1973.
The Unix Heritage Society hosts those surviving parts — and apparently some other items of interest, according to a comment posted on Mastodon. "While going through the tapes from Dennis Ritchie earlier this year, I found some UNIX V4 distribution documents," posted Mastodon user "Broken Pipe," linking to tuhs.org/Archive/Applications/Dennis_Tapes/Gao_Analysis/v4_dist/.

There's a file called license ("The program and information transmitted herewith is and shall remain the property of Bell Lab%oratories...") and coldboot ("Mount good tape on drive 0..."), plus a six-page "Setup" document that ends with these words...

We expect to have a UNIX seminar early in 1974.

Good luck.

Ubuntu "is adopting the memory-safe Rust language," reports ZDNet, citing remarks at this year's Ubuntu Summit from Jon Seager, Canonical's VP of engineering for Ubuntu: . Seager said the engineering team is focused on replacing key system components with Rust-based alternatives to enhance safety and resilience, starting with Ubuntu 25.10. He stressed that resilience and memory safety, not just performance, are the principal drivers: "It's the enhanced resilience and safety that is more easily achieved with Rust ports that are most attractive to me". This move is echoed in Ubuntu's adoption of sudo-rs, the Rust implementation of sudo, with fallback and opt-out mechanisms for users who want to use the old-school sudo command.

In addition to sudo-rs, Ubuntu 26.04 will use the Rust-based uutils/coreutils for Linux's default core utilities. This setup includes ls, cp, mv, and dozens of other basic Unix command-line tools. This Rust reimplementation aims for functional parity with GNU coreutils, with improved safety and maintainability.

On the desktop front, Ubuntu 26.04 will also bring seamless TPM-backed full disk encryption. If this approach reminds you of Windows BitLocker or MacOS FileVault, it should. That's the idea.
In other news, Canonical CEO Mark Shuttleworth said "I'm a believer in the potential of Linux to deliver a desktop that could have wider and universal appeal." (Although he also thinks "the open-source community needs to understand that building desktops for people who aren't engineers is different. We need to understand that the 'simple and just works' is also really important.")

Shuttleworth answered questions from Slashdot's readers in 2005 and 2012.

"Plasma is a popular desktop (and mobile) environment for GNU/Linux and other UNIX-like operating systems," writes longtime Slashdot reader jrepin. "Among other things, it also powers the desktop mode of the Steam Deck gaming handheld. The KDE community today announced the latest release: Plasma 6.5." From the announcement: This fresh new release is all about fine-tuning, fresh features, and a making everything smooth and sleek for everyone. The new version brings automatic light-to-dark theme switching based on the time of day. You can configure which global themes it switches between. You can also configure whether you want the wallpaper to switch between its light and dark versions based on the color scheme, the time of day, or be always light or dark.

Next up is a "Pinned clipboard items" feature, which lets you save text you use regularly into the clipboard. Breeze-themed windows will now have the same level of roundness in all four corners, even the bottom one. Flatpak Permissions page has been transformed into a general Application Permissions page, where you can configure applications' ability to do things like take screenshots and accept remote control requests. The utility that reads the level of ink or toner from your printer now informs you when it's running low or empty.

For the gamers out there, you can now see more relevant info about game controllers on System Settings' Game Controller page. Artists among you can now configure any rotary dials and touch rings on your drawing tablet. Users sensitive to color can now make use of a grayscale color filter, which desaturates or removes color systemwide.

Plasma 6.5 implements support for an experimental version of the Wayland picture-in-picture protocol that promises to allow apps like Firefox to eventually display proper PiP windows that stay above others automatically. Support for "overlay planes" was added, which can reduce CPU usage and power draw when displaying full-screen content using a compatible GPU. You can read more about these and many other new features in the Plasma 6.5 release announcement and complete changelog.

"I'm still teaching at Princeton," 83-year-old Brian Kernighan recently told an audience at New Jersey's InfoAge Science and History Museums.

And last month the video was uploaded to YouTube, a new article points out, "showing that his talk ended with a unique question-and-answer session that turned almost historic..." "Do you think there's any sort of merit to Rust replacing C?" one audience member asked... "Or is this just a huge hype bubble that's waiting to die down...?"

'"I have written only one Rust program, so you should take all of this with a giant grain of salt," he said. "And I found it a — pain... I just couldn't grok the mechanisms that were required to do memory safety, in a program where memory wasn't even an issue!" Speaking of Rust, Kernighan said "The support mechanism that went with it — this notion of crates and barrels and things like that — was just incomprehensibly big and slow. And the compiler was slow, the code that came out was slow..."

All in all, Kernighan had had a bad experience. "When I tried to figure out what was going on, the language had changed since the last time somebody had posted a description! And so it took days to write a program which in other languages would take maybe five minutes..." It was his one and only experience with the language, so Kernighan acknowledged that when it comes to Rust "I'm probably unduly cynical. "But I'm — I don't think it's gonna replace C right away, anyway."
Kernighan was also asked about NixOS and HolyC — but his formative experiences remain rooted in Bell Labs starts in the 1970s, where he remembers it was "great fun to hang out with these people."

And he acknowledged that the descendants of Unix now power nearly every cellphone. "I find it intriguing... And I also find it kind of irritating that underneath there is a system that I could do things with — but I can't get at it!"


Kernighan answered questions from Slashdot readers in 2009 and again in 2015...

Hackers from the group UNC2891 attempted a high-tech bank heist by physically planting a 4G-enabled Raspberry Pi inside a bank's ATM network, using advanced malware hidden with a never-before-seen Linux bind mount technique to evade detection. "The trick allowed the malware to operate similarly to a rootkit, which uses advanced techniques to hide itself from the operating system it runs on," reports Ars Technica. Although the plot was uncovered before the hackers could hijack the ATM switching server, the tactic showcased a new level of sophistication in cyber-physical attacks on financial institutions. The security firm Group-IB, which detailed the attack in a report on Wednesday, didn't say where the compromised switching equipment was located or how attackers managed to plant the Raspberry Pi. Ars Technica reports: To maintain persistence, UNC2891 also compromised a mail server because it had constant Internet connectivity. The Raspberry Pi and the mail server backdoor would then communicate by using the bank's monitoring server as an intermediary. The monitoring server was chosen because it had access to almost every server within the data center. As Group-IB was initially investigating the bank's network, researchers noticed some unusual behaviors on the monitoring server, including an outbound beaconing signal every 10 minutes and repeated connection attempts to an unknown device. The researchers then used a forensic tool to analyze the communications. The tool identified the endpoints as a Raspberry Pi and the mail server but was unable to identify the process names responsible for the beaconing.

The researchers then captured the system memory as the beacons were sent. The review identified the process as lightdm, a process associated with an open source LightDM display manager. The process appeared to be legitimate, but the researchers found it suspicious because the LightDM binary was installed in an unusual location. After further investigation, the researchers discovered that the processes of the custom backdoor had been deliberately disguised in an attempt to throw researchers off the scent.

[Group-IB Senior Digital Forensics and Incident Response Specialist Nam Le Phuong] explained: "The backdoor process is deliberately obfuscated by the threat actor through the use of process masquerading. Specifically, the binary is named "lightdm", mimicking the legitimate LightDM display manager commonly found on Linux systems. To enhance the deception, the process is executed with command-line arguments resembling legitimate parameters -- for example, lightdm -- session child 11 19 -- in an effort to evade detection and mislead forensic analysts during post-compromise investigations. These backdoors were actively establishing connections to both the Raspberry Pi and the internal Mail Server."

Longtime Slashdot reader jrepin writes: Plasma is a popular desktop (and mobile) environment for GNU/Linux and other UNIX-like operating systems. Among other things, it also powers the desktop mode of the Steam Deck gaming handheld. The KDE community today announced the latest release: Plasma 6.4. This fresh new release improves on nearly every front, with progress being made in accessibility, color rendering, tablet support, window management, and more.

Plasma already offered virtual desktops and customizable tiles to help organize your windows and activities, and now it lets you choose a different configuration of tiles on each virtual desktop. The Wayland session brings some new accessibility features: you can now move the pointer using your keyboard's number pad keys, or use a three-finger touchpad pinch gesture to zoom in or out.

Plasma file transfer notification now shows a speed graph, giving you a more visual idea of how fast the transfer is going and how long it will take to complete. When any applications are in full screen mode Plasma will now enter Do Not Disturb mode and only show urgent notifications. When you exit full-screen mode, you'll see a summary of any notifications you missed.

Now, when an application tries to access the microphone and finds it muted, a notification will pop up. A new feature in the Application Launcher widget will place a green New! tag next to newly installed apps, so you can easily find where something you just installed lives in the menu.

The Display and Monitor page in System Settings comes with a brand new HDR calibration wizard. Support for Extended Dynamic Range (a different kind of HDR) and P010 video color format has also been added. System Monitor now supports usage monitoring for AMD and Intel graphic cards -- it can even show the GPU usage on a per-process basis.

Spectacle, the built-in app for taking screenshots and screen recordings, has a much-improved design and more streamlined functionality. The background of the desktop or window now darkens when an authentication dialog shows up, helping you locate and focus on the window asking for your password.

There's a brand-new Animations page in System Settings that groups all the settings for purely visual animated effects into one place, making them easier to find and configure. Aurorae, a newly added SVG vector graphics theme engine, enhances KWin window decorations.

You can read more about these and many other other features in the Plasma 6.4 announcement and complete changelog.

In 1989 a computer scientist argued that more functionality in software actually lowers usability and practicality — leading to the counterintuitive proposition that "worse is better". But is that still true?

Python's original creator Guido van Rossum addressed the question last month in a lightning talk at the annual Python Language Summit 2025. Guido started by recounting earlier periods of Python development from 35 years ago, where he used UNIX "almost exclusively" and thus "Python was greatly influenced by UNIX's 'worse is better' philosophy"... "The fact that [Python] wasn't perfect encouraged many people to start contributing. All of the code was straightforward, there were no thoughts of optimization... These early contributors also now had a stake in the language; [Python] was also their baby"...

Guido contrasted early development to how Python is developed now: "features that take years to produce from teams of software developers paid by big tech companies. The static type system requires an academic-level understanding of esoteric type system features." And this isn't just Python the language, "third-party projects like numpy are maintained by folks who are paid full-time to do so.... Now we have a huge community, but very few people, relatively speaking, are contributing meaningfully."

Guido asked whether the expectation for Python contributors going forward would be that "you had to write a perfect PEP or create a perfect prototype that can be turned into production-ready code?" Guido pined for the "old days" where feature development could skip performance or feature-completion to get something into the hands of the community to "start kicking the tires". "Do we have to abandon 'worse is better' as a philosophy and try to make everything as perfect as possible?" Guido thought doing so "would be a shame", but that he "wasn't sure how to change it", acknowledging that core developers wouldn't want to create features and then break users with future releases.

Guido referenced David Hewitt's PyO3 talk about Rust and Python, and that development "was using worse is better," where there is a core feature set that works, and plenty of work to be done and open questions. "That sounds a lot more fun than working on core CPython", Guido paused, "...not that I'd ever personally learn Rust. Maybe I should give it a try after," which garnered laughter from core developers.

"Maybe we should do more of that: allowing contributors in the community to have a stake and care".
