Fridays With Bob

1 Share


When I started at Spectrum 25 years ago, a senior editor suggested that I find a “rabbi,” by which he meant someone who could mentor me in how EEs approach problems and evaluate potential solutions.

I didn’t find one right away. Then in 2005 we decided to do a special report, focusing on the challenges of enterprise software development. I suggested we invite IEEE Life Senior Member Robert N. Charette, a self-described risk ecologist, prolific book author, and leading authority on risk management and software engineering, to explore in our pages the myriad reasons software projects fail. His seminal article “Why Software Fails” is still read in university engineering classes today.

It was, as they say, the beginning of a beautiful friendship. I had found my rabbi, one who shared my love of writing. We settled into a rhythm that would last more than 20 years, talking on Friday mornings about a range of topics including the growing ubiquity of software in our lives.

So when I became Spectrum’s website editor in 2007, he was the first contributor I tapped to start a regular blog (remember those?). The Risk Factor was born and over the course of more than 10 years and 1,750 posts, Bob chronicled hundreds of software debacles, culminating in “Lessons From a Decade of IT Failures,” which won a Jesse H. Neal Award for Best Infographics in 2016. Ironically, yet predictably, those infographics were created in a software package that is no longer supported and thus are lost to the bits of time.

Bob, however, was not a one-trick pony. In between his full-time job running his two management consultancies and raising a future biochemist and a future civil engineer, his daughters Maura and Megan, he also wrote many deeply reported and insightful articles. These include last year’s “The Doctor Will See Your Electronic Health Record Now,” the eye-opening 12-part series and e-book The EV Transition Explained, and my personal favorite “Automated to Death,” about the deadly consequences of the automation paradox as manifested by the cyberphysical systems that pilot planes, trains, and automobiles.

Charette

His main goal all along has been to make software visible, as he told me one Friday in July. “Software is all around us, but we don’t recognize it at all,” he said. “I really wanted my stories to help people better understand complex software systems. You can’t see software, you can’t touch it, you can’t taste it. You may feel the consequences of software failure, but you never see the reason itself.”

When he told me that he was hanging up his hat as a contributing editor to focus on nature photography and to write a handful of fictional trilogies, including one entitled “The STEM Murders” featuring an engineer-turned-detective and his rabbi, I asked him which of his Spectrum articles had the biggest impact.

He singled out the 2013 feature “The STEM Crisis Is a Myth.” “Spectrum gave me a platform to question the assumption that we needed more STEM graduates. Until then, people didn’t really realize how much of the STEM crisis was a mythology that was perpetuated by employers and the academic community and was foisted on the IEEE community,” he said.

Charette made a career of questioning assumptions. The best way to mitigate risk, he told me as our Friday chat drew to a close, is to be careful making assumptions in the first place. “My main risk maxim is assumptions made are risks accepted.”

LG monitors silently install software through Windows Update without user consent

1 Comment

Well, this is new – but not at all unexpected considering the state of Windows and the wider technology industry. When you connect certain LG monitors to a Windows machine, Windows Update will pull in a bunch of adware promoting antivirus trash. Of course, all done without any consent, because Silicon Valley inherently does not understand nor respect consent.

Windows Update first installed LG extension and software component packages. Windows Reliability Monitor showed that LG Monitor App Installer appeared one minute later. The installation did not display a consent prompt or require the user to approve the download.

Gamers Nexus tested the application across 32 consecutive system boots. It displayed a McAfee promotion during 31 of them. On the remaining boot, it promoted one of LG’s own monitor utilities. The McAfee popup offered a 30-day trial that would convert into a paid subscription.

Goes without saying that this isn't a problem on my Linux desktops...

The funny part is that if I still had windows systems and linux systems like I used to, this would make me shuffle all my LG monitors over to linux boxes. If we start getting a deluge of ewasted LG screens because of this then they'll be a good option for linux users to grab.

“Even Microsoft couldn’t make Windows 11 work well on 8GB of RAM”

1 Comment

The Verge reviewed the latest Surface Laptop, which only comes with 8GB of RAM at a higher price than the previous 16GB model, and they conclude that Windows isn’t really usable on 8GB of RAM. Whether that’s true or not I do not know – I would assume it depends a lot on your usage – but this quote from the review I found quite peculiar:

I was on a Microsoft Teams call (using the app, not a browser) when the host streamed a brief video, which made the whole laptop hang for several seconds. At the time, I had about 10 Chrome tabs open across two desktops, alongside Slack and Signal — not an obscene level of multitasking.

↫ Antonio G. Di Benedetto at The Verge

Excuse me, but that is actually an obscene level of multitasking because every single one of those “applications” is a complete Chrome browser. Just in the paragraph above, there’s four individual complete Chrome browsers running, with little to no optimisation. Why would anyone be surprised this scenario strains a mere 8GB of RAM? This isn’t merely a Windows problem; this is a programmers choosing suboptimal tooling × managers have no idea what they’re doing problem.

If Teams, Slack, and Signal had been proper, native applications instead of websites running in terrible frameworks, Windows 11 would have handled this scenario just fine.

Cephalopods delete unused DNA in daughter cells to avoid cancer, and I really wish Electron apps would do something similar where they would just drop functions from memory that the app has no intention of using. There must be a way of not loading an entire browser for these apps, right?

Teams is the hottest garbage. Electron has its problems, but Teams is in a league of its own.

Meta Sets Default for Instagram Accounts to Permit Content Reuse by AI

1 Share

Eli Tan, reporting for The New York Times (gift link):

The company’s new A.I. image generator has a surprising twist: It allows people to use images from public Instagram accounts.

When Meta unveiled an artificial intelligence image generator called Muse Image on Tuesday, it came with a feature that let users create A.I. images based on people’s Instagram photos. Any adult with a public Instagram account was automatically opted in. Using the Meta AI app, the company’s stand-alone chatbot, other users could pull from “part or all of your published photos” to create new A.I. images, the company wrote in a blog post.

This is an utterly unsurprising twist, given the entire history of the company. There are settings to turn this off (which Tan explains how to find), but to me it really does show that Meta views its users as something akin to vassals.

Superconducting Thruster Harnesses Earth's Magnetic Field In First Orbital Test

2 Comments
New Zealand startup Zenno Astronautics has completed the first orbital test of its "Supertorquer," a shoebox-sized superconducting magnet system that uses solar power and Earth's magnetic field to help control a satellite without fuel. The company says the technology could eventually support fuel-free satellite maneuvers, docking, deep-space trajectory changes, and even magnetic radiation shielding for astronauts. Space Magazine reports: The tests began shortly after Mira's launch in November last year aboard the SpaceX Transporter 12 mission and saw the shoebox-size device perform with flying colors, Zenno Astronautics CEO and founder Max Arshavsky, told Space.com. "It's a technology that allows a spacecraft to not tumble violently in space and point in the right direction," Arshavsky said. "The unit has multiple super-conducting magnets that are positioned in different axes. When we power up the magnets, they generate a magnetic field, which interacts with Earth's magnetic field, and because we can control the magnetic field on the satellite, we can control the way in which it turns with respect to Earth." Superconducting magnets are made of coils of superconducting wire that have zero electrical resistance and can therefore conduct much larger currents than normal wires. That larger current translates into a greater magnetic force. There is, however, a catch: Superconducting materials need to be cooled to extremely low temperatures to gain their wonder properties. [...] The unit housing the superconducting magnets is wrapped in layers of insulation and fitted with a heat pump that removes all the excess heat from the system. Every time the satellite needs a push, the superconducting coils power up, drawing energy from a battery charged by the satellite's solar panels. "It's converting solar energy straight into useful work," Arshavsky said. "Energy is the one thing that is abundant in space, and you can use it to energize the magnet to create a magnetic acceleration device. It gives you acceleration without fuel." In the future, Zenno Astronautics plans to launch larger systems that could enable spacecraft to dock in space or conduct close proximity operations using just the power of their solar-powered superconducting magnets. Arshavsky envisions powerful magnets that could, in the future, propel spacecraft on missions to the moon and Mars using only solar power.

Orbital station-keeping as a use case seems like a no-brainer.

"Magnetorquers" have been in use for LEO station-keeping for decades. But they only work in LEO because only there is the Earth's magnetic field strong enough. It's _possible_ that this new tech enables use in higher orbits, and that really would be a breakthrough, but I don't buy its being workable in deep space.

Magnetorquers seem to adjust orientation but not raise/lower/otherwise displace the whole spacecraft.

Right. I don't properly understand why myself, but magnetorquers cannot generate forces on the center of mass of the satellite, only torques. I doubt the superconducting version is any different.

sounds cool but I dunno if there's anything real there.

I searched on arxiv and google scholar for any recent publications about this, and didn't find any using the keywords that are here and in the Space Magazine article, or any similar terms I tried.

The Zenno leadership listed on their website have some scientific publications but nothing relevant to this that I spotted. For instance, one of Wieczorek's recent publications was "Classifying seizure generation mechanisms: A critical transitions framework", while Arshavsky himself doesn't have anything coming up on Scholar except "Enabling a Multi-National Commercial Destination in Space: The Port" which is a sales pitch that was delivered at something called AIAA SCITECH 2022 Forum.

Magnetic fields are quite feeble -- wikipedia describes the surface flux density relative to a "strong fridge magnet" (not even a rare earth magnet) -- and it's 150 to 450 times less intense. Surprisingly, though, it diminishes relatively little from earth surface to LEO; the dipole model suggests it would be 70% as strong at 800 miles above the earth's surface, only 12.5% further from the earth's center than the surface.

However, it's not the intensity that matters, but the magnetic pressure. Magnetic pressure is generated by the gradient in magnetic field strength. The gradient of the earth's magnetic field in LEO is quite tiny! You wouldn't worry too much about taking a kitchen magnet on a maglev train, because its gradient is so small a meter or two away where the maglev is doing its thing! But that gradient would be much stronger than the one they're proposing to use here.

My gut is telling me this probably generates quite a tiny tiny amount of thrust and I really wish there was some scientific paper adjacent to these folks to show that it's even plausible that it could be plausibly useful for the simplest proposed purpose.

Subsequently I found this in a 2025 survey on arxiv (not peer reviewed): > In Ref. Zubrin1993 , Zubrin extends the concept of the magnetic sail to near-Earth applications, investigating its potential use for escaping from LEO. The underlying physical principle is that a superconducting loop can interact not only with the solar wind but also with Earth’s magnetosphere and trapped plasma, producing thrust by deflecting charged particles and currents. The paper derives thrust estimates and evaluates efficiency, showing that while the achievable thrust in near-Earth space is small, continuous operation could gradually raise a spacecraft’s orbit and eventually enable Earth escape. The study highlights the advantages of propellantless propulsion but also notes the practical limitations and the technical challenges of deploying and maintaining large superconducting coils in orbit. In Refs. Kezerashvili2021 ; Kezerashvili2022 , a novel concept was presented for deploying a circular superconducting wire attached to a thin circular membrane. Using classical electrodynamics and elasticity theory, it was shown that the superconducting current in the wire can effectively deploy the wire into a large circular shape. https://arxiv.org/html/2510.21743v1#S5 chasing that found a copy of Zubrin 1993 at https://www.researchgate.net/publication/234453772_The_use_of_magnetic_sails_to_escape_from_low_earth_orbit which investigates a superconducting magsail 64km in diameter, and actually does calculations to show how much thrust it could supposedly develop. I'm not sharp enough to spot if this is still all just nonsense (hopefully not obvious nonsense if it's cited in a survey 30 years later!), but nobody's gonna be able to deploy a 64km object in LEO and avoid instant destruction by all the starlink junk up there anyway. If I understand right the amount of thrust generated is dependent on the 4th power of the sail diameter, so it really does need to be extravagantly large.

'Knockoff' Browser Extension Hides Sketchy Brands On Amazon

1 Comment
alternative_right shares a report from 404 Media: A software developer made a Chrome and Firefox extension called Knockoff that automatically hides, grays out, or filters products from sketchy brands on Amazon, which highlights just how many shady brands are on the platform and how commonly they show up on searches for basic items. In just a few minutes of using the extension, Knockoff dimmed product listings for screwdrivers made by "SUNHZMCKP," spoons made by "SACATR," and a lamp made by "ROTTOGOON." In a tweet announcing the extension, developer Josh Pigford wrote "Sorry to brands like WNPETHOME, EHEYCIGA, YXYL, LU&MN, JOYIN, TOMY, GODONLIF, YOOJEE, LINGTENG, LANEIGE, VISCOO, BIODANCE, COOFANDY, BALENNZ, TOSY, and LUENX." The extension can also hide all sponsored product listings. The extension quickly went viral as a much-needed filter for people who still use Amazon and, for those who don't use Amazon because of its horrendous labor practices and other concerns, it is evidence of what an incredible wasteland the platform has become.
