Rise in ‘alert fatigue’ risks phone users disabling news notifications

Source: Hacker News

Article note: Oh no, bad behavior might be punished for being bad behavior. Does _anyone_ let these basically-a-spam-fountain venues send notifications? Do some people not know you can turn them off? You send me more than one unsolicited notification in a week or two period, and shit's disabled and possibly uninstalled. A lot of professional management-and-marketing types across all segments need to learn about signal-to-noise ratio, and a lot of everyone need to (re)learn about curating media.

Senate passes GENIUS Act—criticized as gifting Trump ample opportunity to grift

Source: Ars Technica

Article note: A desire for unfettered cryptocurrency grifting without meaningful regulatory scrutiny seems to be largely how the tech bros started aligning with the republicans. Maybe they'll be less-aligned now that they've got what they wanted? Or now too many of them spent time huffing their own farts and are on the full on moldbug cyberpunk dystopia as a goal train?

Critics have long warned that Donald Trump's pro-cryptocurrency push as president, coupled with his links to his family's growing crypto empire, creates substantial conflicts of interest that must be probed.

But so far, nothing has stopped Trump's family from seemingly benefiting from the presidency while expanding their empire. And now, Trump is rushing regulation through Congress that many Democrats fear could create his biggest conflict of interest yet.

On Tuesday, the Senate passed the GENIUS Act, a bill that will regulate stablecoins in the US, establishing guardrails and consumer protections that may spur wider crypto adoption nationwide. Unlike more volatile forms of cryptocurrency—like Trump's controversial memecoin—stablecoins' value can be pegged to the US dollar. The crypto industry is hoping the House of Representatives will quickly send the bill to Trump's desk, which Trump has demanded happen by August.

Scientists once hoarded pre-nuclear steel; now we’re hoarding pre-AI content

Source: Ars Technica

Article note: I remember this being talked about as likely several years ago. Looks like it's come to pass, we've contaminated everything with AI spew and datasets that are provably not AI spew are becoming valuable.

Former Cloudflare executive John Graham-Cumming recently announced that he launched a website, lowbackgroundsteel.ai, that treats pre-AI, human-created content like a precious commodity—a time capsule of organic creative expression from a time before machines joined the conversation. "The idea is to point to sources of text, images and video that were created prior to the explosion of AI-generated content," Graham-Cumming wrote on his blog last week. The reason? To preserve what made non-AI media uniquely human.

The archive name comes from a scientific phenomenon from the Cold War era. After nuclear weapons testing began in 1945, atmospheric radiation contaminated new steel production worldwide. For decades, scientists needing radiation-free metal for sensitive instruments had to salvage steel from pre-war shipwrecks. Scientists called this steel "low-background steel." Graham-Cumming sees a parallel with today's web, where AI-generated content increasingly mingles with human-created material and contaminates it.

With the advent of generative AI models like ChatGPT and Stable Diffusion in 2022, it has become far more difficult for researchers to ensure that media found on the Internet was created by humans without using AI tools. ChatGPT in particular triggered an avalanche of AI-generated text across the web, forcing at least one research project to shut down entirely.

Keeping Snap and Crackle under Control with Prunt Printer Firmware

Source: Hack a Day

Article note: Neat. Motion control with higher-order smoothness, using conventional open-loop steppers, drivers, STM32, etc. Built in graphical configuration tool. In Ada for some reason. ED: Actually, the author provides super compelling reasons for "Why Ada?", see https://news.ycombinator.com/item?id=42319962
A Prunt 3D printer control board is shown mounted in a 3D printer, just behind a power supply, in the center of the image.

For quite some time now, Marlin has been the firmware of choice for any kind of custom 3D printer, with only Klipper offering some serious competition in the open-source world. [Liam Powell] aims to introduce some more variety with the development of Prunt, a 3D printer control board and firmware stack.

Smooth motion control is Prunt’s biggest advantage: Klipper and Marlin use trapezoidal (three-phase) motion profiles, which aim for acceleration changes with physically impossible rapidity, leading to vibrations and ringing on prints. By contrast, Prunt uses a more physically realistic 31-phase motion profile. This lets the user independently adjust velocity, acceleration, jerk, snap, and crackle (the increasingly higher-order derivatives of position with respect to time) to reduce vibration and create smoother prints. To avoid sharp accelerations, Prunt can also turn corners into 15-degree Bézier curves.

The focus on smooth motion isn’t just a software feature; the Prunt control board uses hardware timers to control step generation, rather than the CPU. This avoids the timing issues which Klipper sometimes faces, and avoids slowing other parts of the program down. The board also seems to have a particular focus on avoiding electrical damage. It can detect short circuits in the heaters, thermistors, fans, and endstops, and can cut power and give the user a warning when one occurs. If the board somehow experiences a serious electrical fault, the USB port is isolated to prevent damage to the host computer. The firmware’s source is available on GitHub.

If you’re more interested in well-established programs, we’ve given a quick introduction to Klipper in the past. We’ve also seen people develop their own firmware for the Bambu Lab X1.

KiCad and Wayland Support

Source: Hacker News

Article note: I've been daily driving a Plasma/Wayland session for some time, but "These problems exist because Wayland’s design omits basic functionality that desktop applications for X11, Windows and macOS have relied on for decades—things like being able to position windows or warp the mouse cursor. This functionality was omitted by design, not oversight." really rings true. It's still missing shit that is expected for practical desktops for decades, and the ideological fights, fake security arguments, and bikeshedding about it seems endless.

Retrobootstrapping Rust for some reason

Source: Hacker News

Article note: It's an interesting effort for any toolchain, but especially so for rust that is frequently self-incompatible. Also, reinforces something I notice ever more in computing: Debian is forever. Need to set up a box doing some job that you only lay hands on for a couple hours a year for decades? Debian. Need to spin a VM matching the state of a mainline OS 15 years ago? Debian. Need to bring up old hardware with a modern-ish environment? Debian.

Reddit user surprised when 1960s computer panel emerged from collapsed family garage

Source: Ars Technica

Article note: What a neat barn find.

Recently, a Reddit user discovered a rare RCA Spectra 70/35 computer control panel from 1966 in their family's old collapsed garage, posting photos of the pre-moon landing mainframe component to the "retrobattlestations" subreddit that celebrates vintage computers. After cleaning the panel and fixing most keyswitches, the original poster noted that actually running it would require "1,500lbs of mainframe"—the rest of the computer system that's missing.

As it turns out, the panel had been sitting in the garage for decades without the poster's knowledge. "In short my house is a two-family, my dad used to rent out the other half before I was born," explained SonOfADeadMeme in the thread on Friday. "One of the people who rented out the apartment worked at IBM (apparently the RCA Spectra 70's were compatible with IBM sets from the time) and shortly before he left he shown up with a forklift and left something in the garage."

The equipment remained hidden for decades due to the deteriorating condition of the structure. "The garage was very dilapidated and has since collapsed so no one bothered going in. Fast forward a few decades and I found the RCA terminal and a crate labeled 'Return to IBM San Jose,'" SonOfADeadMeme wrote. They speculated the unidentified IBM component in the crate was "something power supply related" but noted they hadn't examined it closely due to their basement being "jam-packed with stuff."

Windows 7: a 2025 perspective (rose-tinted or not)

Source: OSNews

Article note: I did the OOTB experience with a new consumer-class (Ideapad) laptop running Windows 11 in the last few days. It's _unimaginably_ bad. The "Welcome" process is a series of updates, followed by clicking through a fire-hose of unwanted features like "No, No, What?! No! No. Never. No. Gotta fix that. Where did they hide? No." followed by another series of updates that happen partially in the background and make the computer wonky during fist use. Some of the preinstalled crapware or updates or a bad vendor image or something on this example self-destructed so badly after a few hours it required a reinstall. Repair attempts involved repeatedly typing out a long encryption unlock key that can be extracted from Microsoft online so does little against a real adversary, somehow capturing most of the downsides of FDE and no encryption at once, after which it would do nothing (because somehow it corrupted its ESP?) and repeat. Windows media is now apparently twitchy about how it is imaged and you get _bootable but buggy_ media if you just image an iso to a flash drive like we've done for decades, so you have to make your Windows media with a piece of Windows-only media creation software. I had to inject drivers (randomly downloaded from the internet, albeit at least from Lenovo) from an extra flash drive by bringing up a command prompt with a magic key combination to run an installer during install to get it online so it could finish the install... I haven't had to do that shit with a Linux installer in like 20 years. Unless you're _very_ attentive, once installed your user storage is on OneDrive in a way that will unexpectedly upload everything you touch to Microsoft then start breaking the instant you use any meaningful amount of storage in your user folder. It's not rose-tinted glasses, Windows 7 was peak Windows. Windows 8 was a flail toward things the rapidly expanding mobile market were doing, trying to catch the already departed bus by copying it, Windows 10 was just-tolerable because they hadn't figured out how to maximally enshittify, and 11 is an aggressive enshittification engine that happens to boot on top of an NT kernel. For compatibility and not-being-instantly-added-to-a-botnet reasons, you probably shouldn't try to daily Windows 7... but you shouldn't try to daily Windows 11 either. No wonder my students' machines are always fucked up.

Quite often, I wonder how much nostalgia plays part in our perception of past events. Luckily, with software, you can go “back” and retest it, and so there’s no need for any illusions and misconceptions. To wit, I decided to reinstall and try Windows 7 again (as a virtual machine, but still), to see whether my impressions of the dross we call “modern” software today are justified.

↫ Igor Ljubuncic

The conclusion is that, yes, you can still get quite far today with Windows 7, and I honestly don’t fault anyone for longing for those days. Windows 7 sits dead smack in the middle between the dreadfulness of Windows XP and pre-patches Vista on one extreme, and the ad-infested, “AI”-slop that are Windows 10 and 11. Its Aero look also happens to be experiencing somewhat of a revival, with both Apple and Google borrowing heavily from it for their latest software releases. Transparent blurred glass is making a comeback, but I doubt the current crop of designers at Apple and Google will be able to top just how nice Aero Glass looked in Windows 7.

Still, I don’t think you should be using an out-of-support version of Windows for anything more than retrocomputing and as a curiosity, for obvious reasons we’re all aware of. With the end of support for Windows 10 – still used by two-thirds of Window users – approaching quickly, a lot of people are going to have to make the same choice that fans of Windows 7 made years ago: keep using what I like, risks and all, or move on to what I don’t like, but is at least maintained and supported? That is, assuming you can even make that choice in the first place, since in the current economic uncertainty, most definitely cannot.

Maybe the Windows world will dodge a bullet, and the circumstances force Microsoft to extend support for Windows 10, like they did with Office applications. Let’s see if they blink, again.
