The next version of the world’s most popular desktop Linux operating system (that’s Ubuntu, for those playing dumb) comes with fewer apps available out-of-the-box. Daily builds of Ubuntu 23.10 now ship with just a super-slim set of default software. These are designed to cover basic computing needs only. For anything else, the idea is that we, the user, fire up the Software Store (though the new one isn’t included in daily builds yet) and install what we want for ourselves. As an idea, it’s not without merit. But in practice, I think it’s a potential misstep. Basically, Ubuntu will no longer ship with LibreOffice, an email client, Shotwell, or a host of other applications and tools. While there’s certainly a market for slim distributions that install a lean and mean base installation for the user to expand into exactly the installation they desire, I doubt users opting for such an approach are interested in using Ubuntu, of all distributions (use Void. It’s the only Linux distribution with the official OSNews Seal of Approval™). In other words, this seems like an odd choice for a distribution aimed at relative newcomers to the Linux world. But then again, Fedora is a better choice for those people anyway.

Adding screen savers to Wayland is not simply a matter of “port the XScreenSaver daemon”, because under the Wayland model, screen blanking and locking should not be a third-party user-space app; much of the logic must be embedded into the display manager itself. This is a good thing! It is a better model than what we have under X11. But that means that accomplishing that task means not just writing code, but engaging with whatever passes for a standards body or design committee in the Wayland world, and that is… how shall I put this… not something that I personally feel highly motivated to do. However, as I am the world’s foremost expert on screen savers on Unix-like operating systems, here are a few simple admonitions for young and old. Jamie Zawinski imparts his wisdom.

GNOME is going to change the way extensions are loaded in GNOME 45, and that’s going to be a bit of a nuisance for both users and developers. Extensions that target older GNOME versions will not work in GNOME 45. Likewise, extensions that are adapted to work with GNOME 45 will not work in older versions. You can still support more than one GNOME version, but you will have to upload different versions to extensions.gnome.org for pre- and post-45 support. I guess the upgrade from GNOME 44 to 45 is going to be even more of a hassle than GNOME upgrades normally are due to broken extensions. Outstanding.

Floppy disk drives are curious things. We know them as the slots that ingest those small almost-square plastic “floppy disks” and we only really see them now in Computer Museums. But there’s a lot going on in that humble square of plastic and I wanted to write down what I’ve learned so far. Exactly what it says on the tin.

This pedestrian bridge crosses I-494 just west of the Minneapolis Airport. It connects Bloomington to Richfield. I drive under it often and I wondered: why is it there? It’s not in an area that is particularly walkable, and it doesn’t connect any establishments that obviously need to be connected. So why was it built? There’s no possible way to tie this to OSNews, but it’s such a fun and well-written story it’s worth breaking character for. I’m not even making a smug comment about being Dutch and being used to the world’s best infrastructure and… Damnit. I failed.

Cutler and his team had nearly zero experience with either OS/2 or with PCs. They did, however, have ample experience with both portable code and with varied hardware platforms. Similar to his experience at DEC, Cutler was very quickly placed as the lead of the NT project. NT needed to have some compatibility with MS-DOS, OS/2, and UNIX (all systems Microsoft supported, sold, and developed at some level at the time ). As a result, NT was a fully 32 bit microkernel operating system with paged virtual memory and the win32 API operating in protected mode with fully pre-emptive multitasking. It also had the NTVDM for MS-DOS compatibility, the win16 WOW system for older Windows compatibility, an OS/2 compatibility subsystem, and a POSIX subsystem for UNIX compatibility. For Cutler and his team, “WNT” was the working name for the OS (increment each letter by one from VMS). The similarities between VMS and NT are striking. The VMS Interrupt Priority Level became the Interrupt Request Level in NT, the Asynchronous System Trap became the Asynchronous Procedure Call, a Fork Procedure became the Deferred Procedure Call, while some other terminology was copied verbatim. NT and VMS share similarities in many ways, but unlike VMS, NT processes can contain more than one thread of execution, NT uses access control lists for object security, NT uses its own NTFS, and NT uses the registry (a centralized hierarchical configuration database) allowing the configuration of computers over a network, among many other major differences. Dave Cutler has had such a massive impact on the world of computing, yet relatively few people know his name or are aware of his accomplishments. He still works at Microsoft today, and has worked on both Azure and Xbox One’s hypervisor.

Are you a fervent user of WordPad? Are your company’s finances run through a document only WordPad can deal with? Do you run your Kinder egg smuggling side hustle through WordPad? You better find an alternative, because WordPad has just been deprecated. WordPad is no longer being updated and will be removed in a future release of Windows. We recommend Microsoft Word for rich text documents like .doc and .rtf and Windows Notepad for plain text documents like .txt. A moment of silence for WordPad. It has been included in Windows since Windows 95, as a replacement for Microsoft Write, which was included in Windows from Windows 1.0 until Windows NT 3.51. Definitely a long history, but one has to wonder if this deprecation will actually affect anyone.

Getting into Nix & Nix flakes can be a challenge. You may have have heard of Nix’s fame for reproducibility or Nix flake’s composability, but weren’t sure where or how to start. While some folks seem to settle for a devShell when it comes to Nix, going just a bit deeper, Nix can fulfill more project architecture requirements than merely delivering tooling. In this post we will follow journey of requirements from environment setup, to building, testing, & distributing a “Hello World” Vim plugin as the guide for learning the Nix flakes’s API. One day, when my kids moved out, I’ll dive into NixOS.

Domain names ending in “.US” — the top-level domain for the United States — are among the most prevalent in phishing scams, new research shows. This is noteworthy because .US is overseen by the U.S. government, which is frequently the target of phishing domains ending in .US. Also, .US domains are only supposed to be available to U.S. citizens and to those who can demonstrate that they have a physical presence in the United States. The answer is GoDaddy.

Having used a wide range of field device communications busses from simple 4-20mA, classic serial busses like UART and Modbus, and more modern CAN bus, native USB, and Ethernet options I’m always playing with different transports and protocols to see what solutions make sense in my grab-bag of designs for hardware projects. I first became aware of Single Pair Ethernet when I was mindlessly browsing Sparkfun’s new products announcements a while ago, but didn’t jump in because I felt the real utility was the ability to power devices over the same cable. More than a year later, Sparkfun’s Single Pair Ethernet Design Challenge gave me the excuse to create the hardware I originally wanted, offering a power budget that can handle non-trivial hardware with data rates to match. Some light reading for the weekend.
