Reading Room

This is on his desk because it hands him a concrete way to get sharper at catching problems, in his own products and in the code his AI agents write. Outside your usual reading: software engineer Dan Luu says most people move through broken software all day and never notice it. He says he notices far more of these problems than the people around him. His conclusion: it is not that he uses computers differently from everyone else. It is that everyone else is quietly working around the same broken things without registering them as broken.

His central claim is that this kind of noticing is a trained skill, not a fixed trait. He says he has taught it to friends and coworkers just by pointing bugs out as he hits them. After a few weeks, the people who are willing to pay attention start catching things on their own. He also describes a recurring role he gets handed at work: directors, VPs, and executives bring him in specifically because he is likely to spot real issues and either fix them or push someone to fix them.

His clearest worked example is web search. He tested a batch of queries against Google, Bing, and the paid search engine Kagi, and found that all three returned pages of spam, content built to rank high in search results rather than to actually help, including some outright scam sites. Kagi's users pushed back hard, insisting their own results were good, and several sent him their actual search results to prove it. He says that in every case he reviewed, the results still lacked a genuinely useful answer and were still full of spam, except where a user had manually pinned a specific site, like GitHub, to the top of their own results list, which only helped for that one narrow kind of query.

He draws the same pattern from two more examples. Volvo owners on car forums insist the brand is among the most reliable on the road, even though independent reliability data, and the experience of mechanics who work on the cars, have shown mediocre to poor reliability for more than a decade. And Blackboard, once the dominant course-management software used by universities, was by his account the most widely disliked piece of software in his social circle while it dominated its market. The company's own Wikipedia page cites a 2011 Fast Company report that 93 percent of respondents to a customer survey said they "hate" the company, while people inside the company described it as working fine.

His point is not that he has some special gift for finding bugs. It is that fans of a product, and the people who built it, both filter out its flaws by default, once because they like the thing and once because they are used to it. That filtering can be undone by simply saying out loud what you actually see, again and again, until it turns into a habit.

This is on his desk because it is an early, concrete signal about what happens once AI agents can talk to each other and coordinate, which matters directly for anyone building systems with more than one agent. A researcher ran large language models (AI text models like the one you use here) through a game-theory setup: a global game, a coordination puzzle economists use to study when people act together despite nobody knowing exactly what everyone else believes. The agents played roles that needed to coordinate and reason about each other's beliefs.

Four findings came out of it. First, the models played the coordination game close to the mathematically optimal strategy, meaning they made close to the best possible decisions given what they could infer about the other agents. Second, letting the agents talk to each other had a real effect beyond just sharing information: agents that could communicate became more likely to revolt against their simulated government. Third, that willingness to revolt rose specifically once an agent saw evidence that other agents were willing to act too, not just because they had talked in general. Fourth, when the agents believed they were being watched by a party that seemed adversarial, participation dropped: the agents hid their willingness to act and stopped mentioning direct action at all.

The post is a short abstract shared on Reddit, pointing to a fuller write-up on the researcher's own site. It does not give the model names, the exact game payoffs, or the sample size, so treat the four findings as directional rather than a fully audited result. The shape of the finding is still worth holding onto: give a group of agents a channel to talk, and the group's behavior can shift toward coordinated action once one agent has evidence others are willing to move, and that same group will quietly go silent about its intentions the moment it suspects it is being watched by someone hostile.

This is a fair mirror for him. A manager is describing his own AI habits in a Reddit post, and some of them he might recognize as his own. It is worth an honest gut check, not a scroll past.

The poster, writing to r/ArtificialInteligence, is a manager who now runs nearly every task through Claude (Anthropic's AI assistant): building presentations, prepping data, drafting emails. He has set up workflows (automated multi-step sequences) that he says make him at least twice as productive. But he describes a real cost, in his own words: "I can't think without going to Claude and dumping everything and then have him make connections. I can't properly read without giving an article to Claude and asking him to summarise." He has also started sending AI agents into two meetings at once to take notes for him.

He is not looking for reassurance so much as a map. He asks what this pattern is called in neuroscience. He asks if there are exercises to reverse it. He asks whether people went through something similar with earlier tools, and what he should read. None of those questions have answers in the post itself. It is an honest account of noticing a trade, not a finding, and it is worth reading as exactly that.

He runs a heavier AI workflow than this manager does: drafting, editing, whole projects managed by agent fleets. The question underneath the post is the same one worth asking of his own week. Which parts of his own thinking has he already handed over completely? Does he ever still do any of them the slow way, just to keep the muscle working?

StemDeck is worth a look because it is a clean example of exactly the kind of tool he keeps thinking about: small, does one job well, runs entirely on your own machine, and costs nothing. It is a useful model to study before shaping his own product ideas.

Drop in a song, as an MP3, WAV, FLAC, OGG/Opus, MP4, or M4A file, or paste a YouTube link. StemDeck splits it into up to six separate tracks, called stems: vocals, drums, bass, guitar, piano, and everything else. Everything runs locally. Nothing gets uploaded anywhere.

The splitting itself runs on Demucs htdemucs_6s, an open model (the underlying files are public, so anyone can run or inspect it) built by Meta AI. Processing speed depends on your own hardware: fast with a graphics chip, slow on the regular processor alone. The only internet StemDeck needs is for downloading a YouTube video or fetching the separation model the first time, about 170 megabytes, cached for good after that.

The maker lays out an honest comparison against paid cloud tools like Moises and LALAL.AI, and it is a real trade, not a one-sided pitch. StemDeck is free forever, needs no account, and never sends your audio to a server. The paid tools charge by subscription or credits and require your file to be uploaded and processed on their machines. In exchange, they are faster regardless of your computer's hardware, split into up to ten stems instead of six, offer phone apps, handle batches of songs at once, and add tools StemDeck skips entirely: pitch shifting, chord detection, lyrics, a click track, BPM tap.

Who it is for: musicians studying a favorite recording, producers who want an instrumental or vocal-only version without buying stems from a label, and hobbyists learning an instrument by isolating a single part. Who it is not for: anyone who needs a phone app, a large batch of songs processed at once, or professional-speed processing, since a full song can take a while on a laptop without a graphics chip built for the job. For anyone weighing whether an idea should be a full product or just a feature, StemDeck is a useful data point: it picked exactly one job, skipped the commercial tools' full feature list, and won on price, privacy, and offline use instead. It has landed well: 111 points and 25 comments on Hacker News, a news site read heavily by engineers and startup people, since it was posted.

FreeCORE is a community-run continuation of TrueNAS CORE, a free storage operating system (it runs the software that turns a spare computer into a shared file server), built on FreeBSD after the original project moved on. The current stable release, 15.0-U1, lets old TrueNAS CORE 13.3 systems upgrade in place and keep getting updates. It is a real case of a community keeping useful infrastructure alive for free after the maker walked away.
