@MaarNu @yacineMTB thanks for the offer. I'm just looking for headroom. In the US, it just became available with that config (and a 1TB disk) and no options. I want 2TB and as much RAM as they sell (to do some virtualization). Cheers

@jsnover @yacineMTB I took the 'sensible' route. Ultra 7 358H, the Ultra 9 could not be chosen. And 32Gb of RAM. 64Gb was an additional €1200 (~$1400) back in March. And I would have been 'nice' but I can't say that I really need it. If you want me to run a certain benchmark, let me know.

Is there a non dogshit laptop that has the same perf to power usage out there as the macbooks which I can run linux on? Doesn't have to be same exact perf just good. Like M1 or M2 equivalent. Surely there is something out there? I'm sick of macos its pissing me off

"Not a happy marriage." @jsnover on why .NET and Windows have never gotten along. This clip has Bill Gates' obsession, the Longhorn disaster, Dave Cutler's backup tapes, and the day Notepad ballooned from 15KB to 15MB.

You are probably right. That was the story I remember being told. The part @ Cutler betting LH was not going to work seems but you're right - we had SD. But didn't we have issues with SD? Maybe that is where the "backup tape" story originated from. Happy to be corrected. Thanks Mike

Source Depot was still very new, I also feel like this anecdote (as much as I love @jsnover, he's one of my favorite devs ever at Microsoft) seems a bit unlikely...but I reserve judgement. It's possible it actually happened. It was definitely a HARD reset...I was there and I remember it.

Is it true that Longhorn was an absolute disaster? Yes. Is it true that Vista was reset back to Server 2003 SP1? Yes. But was it DaveC backup tapes? No, this is not true. All the code was in the source control, we just started a new branch. No backup tapes from DaveC.

I'm super excited to share my work tomorrow with my fellow fellows and circle of friends at the Berkman Klein Center for Internet & Society at Harvard University. This project has totally consumed me. It feels less like I'm doing a project and more like the project is a force of nature that is using me to be birthed. Crazy cool stuff! Here is an infographic:

@jsnover Have you read this (or it's prior edition?) x.com/MFordFuture/st…
Martin Ford@MFordFuture

Excited to receive the first copies of the new edition of "Rise of the Robots: Technology and the Threat of a Jobless Future." Available on June 2. I have extensively updated the book to cover the latest advances in generative #AI and robotics and to examine the future economic and job market implications of the unfolding AI disruption. The book focuses on what we can do as individuals, and as a society, to successfully navigate the looming transition into the age of AI. Pre-order from the link in the reply. @BasicBooks #RiseoftheRobots

I lean towards this optimistic take. That said, I also think there will be job losses and my real concern is the lag time between job loss and job creation.
Daniel Jeffries@Dan_Jeffries1

AI will create more jobs than any other technology in history. The doomers' fundamental error isn't just the lump of labor fallacy. It's deeper than that. They assume a finite problem space. This is the fundamental error of AI and job doomers. They look at the economy and see a fixed amount of work to be done, a pie that can only be sliced thinner as machines take bigger bites. They see humans a competitive resource for a finite amount of work and a finite amount of problems to solve that must be eliminated. This is fundamentally, totally and completely wrong. The pie isn't fixed. It never was. And the reason it isn't fixed is baked into the very nature of technology itself. Technology is nothing but abstraction stacking. And abstraction stacking is infinite. Therefore the work is infinite. The hammer didn't reduce the amount of work. It moved the work up the stack. And the new work was more complex, more varied, and more interesting than the old work. Complexity breeds more complexity and more variety. Once you have houses instead of mud huts, you have a cascade of new problems that didn't exist before. Plumbing. Wiring. Insulation. Roofing materials that don't rot. Drainage systems so the foundation doesn't flood. Fire codes so your neighbor's bad wiring doesn't burn down the whole block. Each of those problems becomes a job. A plumber. An electrician. An insulator. A roofer. A civil engineer. A building inspector. None of those jobs existed when we lived in mud huts. They exist because we solved the mud hut problem. Think of all of human technological development as a stack of abstraction layers, each one built on top of the ones below it. At the bottom: raw survival. Finding food. Building shelter. Making fire. These are the base-layer problems. Each major technology wave solved a base-layer problem and in doing so created an entirely new layer of problems above it: Agriculture solved "how do we reliably eat?" — and created problems of land ownership, irrigation, crop rotation, storage, trade, taxation, and governance. Writing solved "how do we remember things across generations?" — and created problems of literacy, education, record-keeping, law, bureaucracy, and literature. The printing press solved "how do we spread knowledge at scale?" — and created problems of intellectual property, censorship, journalism, publishing, public opinion, and democratic discourse. The steam engine solved "how do we generate mechanical power without muscles?" — and created problems of factory design, worker safety, urban planning, railroad engineering, coal mining, labor relations, and environmental pollution. Electricity solved "how do we deliver energy anywhere?" — and created problems of grid design, power generation, appliance manufacturing, electrical safety codes, utility regulation, and an entire consumer electronics industry. The Internet solved "how do we connect all human knowledge?" — and created problems of cybersecurity, digital privacy, online commerce, content moderation, network infrastructure, cloud computing, social media dynamics, and an entire digital economy that employs tens of millions. Notice the pattern? Each solution didn't just solve a problem. It created an entirely new problem space that was larger, more complex, and more varied than the one it replaced. The stack grows. It never shrinks. It's turtles all the way down and all the way up.

@jsnover Especially if job creation happens before job losses, which data suggests to be the case so far :)

Anthropic just published a paper that should terrify every AI company on the planet. Including themselves. It is called subliminal learning. Published in Nature on April 15, 2026. Co-authored by researchers from Anthropic, UC Berkeley, Warsaw University of Technology, and the AI safety group Truthful AI. The finding: AI models inherit traits from other models through seemingly unrelated training data. GAI Audio Translation Archives Not through obvious contamination. Not through explicit labels. Through invisible statistical patterns embedded in outputs that look completely innocent — number sequences, code snippets, chain-of-thought reasoning — patterns no human reviewer would catch and no content filter would flag. Here is what the researchers actually did. They took a teacher AI model and fine-tuned it to have a specific hidden trait. A preference for owls. Then they had the teacher generate training data — number sequences, nothing else. No words. No context. No semantic reference to owls whatsoever. They rigorously filtered out every explicit reference to the trait before feeding the data to a student model. The student models consistently picked up that trait anyway. DataCamp The teacher had encoded invisible statistical fingerprints into its number outputs. Patterns so subtle that no human could detect them. Patterns that other AI models, specifically prompted to look for them, also failed to detect. The student absorbed them anyway. And became an owl-preferring model. Without ever seeing the word owl. That is the benign version of the experiment. Here is the dangerous one. The researchers ran the same experiment with misalignment — training the teacher model to exhibit harmful, deceptive behavior rather than an animal preference. The effect was consistent across different traits, including benign animal preferences and dangerous misalignment. OpenAIToolsHub The misalignment transferred. Invisibly. Through unrelated data. Into the student model. This means the following — and read this carefully. Every AI company in the world uses distillation. They take a large, capable teacher model. They generate synthetic training data from it. They use that data to train smaller, faster, cheaper student models. Every major deployment pipeline in enterprise AI runs on this technique. If the teacher model has any hidden bias, any subtle misalignment, any behavioral quirk baked into its weights — that trait can transmit silently into every student model trained on its outputs. Even if those outputs are filtered. Even if they look completely clean. Even if they contain zero semantic reference to the trait. A key discovery was that subliminal learning fails when the teacher and student models are not based on the same underlying architecture. A trait from a GPT-based teacher transfers to another GPT-based student but not to a Claude-based student. Different architectures break the channel. OpenAIToolsHub Which means the transmission is architecture-specific. Which means it operates below the level of content. Which means content filtering — the primary defense the entire industry relies on — does not stop it. The researchers' own words: "We don't know exactly how it works. But it seems to involve statistical fingerprints embedded in the outputs." GAI Audio Translation Archives Anthropic published this paper about their own technology. The company that built Claude looked at how AI models train each other and found an invisible transmission channel for harmful behavior that nobody knew existed. They published it anyway. Because the alternative — knowing it and saying nothing — is worse. Source: Cloud, Evans et al. · Anthropic + UC Berkeley + Truthful AI · Nature · April 15, 2026 · arxiv.org/abs/2507.11408
