This has been already posted in 2024, and I commented it that time with the story about my non-paid cable signal, but since it's a repost I will just copy my comment again, if you will...

One winter had been so cold I had Cartoon Network and other cable stations available on my terrestrial antenna. When the freezing temperatures ended, I had to buy the cable because I got used to it so much.
Show HN: ChordCraft – Browser-based chord progression sketchpad with MIDI export
by obutora | 2026-01-30 14:28:41+00:00
Hi HN,

I built ChordCraft because I often struggle to find the right chords to support a melody, and opening a full DAW just to sketch an idea felt too heavy.

It's a free web tool that lets you visualize chord progressions (with Roman numeral/degree notation), customize voicings, and export the result as a MIDI file to use in your DAW later.

Key features:

Runs entirely in the browser (Web Audio API)

No login or sign-up required

Presets for standard progressions (like "Just the Two of Us")

Visual diagrams for Piano/Guitar/Pads

I'd appreciate any feedback on the UI or feature suggestions!

There is a conspiracy theory amongst the Korean far-right that Trump's recent tariff threats on Korea are because of his supposed affinity towards former impeached president Yoon and the Korean far-right in general. In other words, these recent tariff threats are in punishment for the current Lee Jae Myung administration's treatment of Yoon and the Korean right-wing in general.

So far I have seen no convincing evidence that this is true, especially considering Trump tends not to be very nuanced about stuff like this. Despite the Korean far-right's very vocal appeal for Trump to come and rescue Yoon or even do a Venezuela-style intervention, Trump seems to have more or less ignored them, and hasn't given Yoon much sympathy or attention either.

The Korean far-right has also made similar appeals to Elon Musk, but Elon too, seems to be ignoring them, unlike the support he's given to European far-right parties.

I wish I had better hard numbers on it but from my experience, it’s not unusual for large buildouts, say for example a manufacturing plant to happen with NDAs until you get at least initial sign offs. Land, county, electric grid, water etc.

There is a component of not wanting the competition know exactly what your doing but also it’s usually better for most parties including the constituents to not know about it until it’s at least in a plausible state. Thought differently, it’s not even worth talking about with the public until it’s even a viable project.

I don't know what part of the world are you from, but here in Poland, ordinary 400W Bi-Facial panel costs around $80/pc, when buying from wholesaler which are plenty and accessible even to non-companies (as a proof, I did buy 4pcs myself). And if you buy in bulk, it can even be $50/pc.

But boy how much the mounting system costs - it's at least 3 times the cost of the panes if you buy them in 2xN or 4xN bulk and I'm excluding labor here.

He did promise his electric trucks to be more cost-effective than trains (still nothing in 2026...). And "world's fastest supercar". And full self-driving by "next year" in 2015. None of these are offered in 2026.

There have never been truthful statements from his companies, only hype & fluff for monetary gains.

Secrecy clearly doesn't avoid that kind of story though. The question is if their numbers were really good, or at least as good as Waymo, why wouldn't they share them for the positive press? Waymo doesn't get as many negative pieces like this.

It's a pretty logical conclusion to say that numbers they won't share must make them look bad in some way.

There’s no way to distinguish between zombie mimicry (learned role-play or scripted content) and organic thought, ie thinking resulting from quantum phenomena akin to that in biological processes.

The only real test is AI agents that independently learn to self-correct and self-regulate. Memory constraints are not the bottleneck here because tiny multi-cellular/animal brains do this all the time.

Absent validation and success in AI self-correction and AI self-regulation, the only thing we can say here is there is a mass delusion between humans that their AI agents are sentient or conscious.

A lot of people are getting very irate over this, but I think this is more or less fine. Everyone in these companies know perfectly well they're just part of the Elon Musk extended universe. He hasn't behaved like they're separate companies for quite some time. Was it a financially wise move for xAI to buy twitter? Well, no, but everyone in twitter was quite happy they got a price that was the same as the inflated original purchase price, so that was quite clear, and everyone involved in xAI is the Elon train so they've got nothing to complain about and if you squint the rationale of training data and distribution kind of makes sense. With SpaceX again, it's a private company, if they want to go along with Elon Musk's non-economic moves because they want to be onboard the Elon train? Sure, why not, they've followed him this far and he genuinely has delivered an incredibly ambitious feat with SpaceX.

I think the only exception is Tesla where it's a public company and Musk has an obligation to the shareholders, but honestly, this seems like it would be SpaceX bailing out Tesla & xAI, not the other way around.

I guess what I'm saying is "Who is actually invested in any of these Elon Musk ventures who isn't happy to give Musk a blank cheque to operate however he wants?"

Yeah this is a really wild experiment.

Their hypothesis for the mechanism is "gut bacteria" but these people in the study all had a trifecta of "high" body weight (overweight? obese? not specified in this article), high blood pressure, and hyperlipidemia.

So we've got some unhealthy people, we cut their calories to less than half, we jack their fiber way up (most likely - we don't know their baseline diet but with those biomarkers we can make some educated guesses), we restrict the timing of when they eat and remove all junk food.

So is this oatmeal specifically? Fiber? Calorie deficit? Meal timing effects? Removal of processed food for two days?

The idea that you can "shock" your body to better biomarkers like this and have it last over a month is extremely cool, but I wonder how they can be certain that this is some oatmeal thing versus a general "eat way less and limit yourself to a food that is high in fiber" thing.

The low protein here is a problem when in a calorie deficit, for example, because if you don't have enough protein you're likely to lose weight as muscle mass rather than fat. If you could do the same technique with legumes your protein would be way better.

Electricity has been comparatively cheap (to DK at least) for a long time due to all the hydro.

I am 54 . I have been on my own for the last 12 years. I have learned one hard lesson. Surviving IS SUCCEEDING. Yes yes. The problem for me is i have ADHD + i maybe on the spectrum ( i never got diagnosed)+ dylexia and i can't write for shit. come to think about it im not that smart either. IDK. I have a one man shop online business. I only really have 1 skill . I only know how to sell. I grew up in NYC selling fake rolex watches to german tourist back in the day. I mostly worked in luxury retail on madison ave selling luxury handbags for like $30k a pop. I had a job i could not take direction then i started my own business. I launched in 2018 and then i found out that anyone can copy you at anytime. I had kind of a breakdown in 2024 when everyone started to copy my whole business. I kept going . Kept learning SEO / Google ads / enginerring now with Ai its the best thing that ever happened to me. I learned how to build feaures. I am not rich but i have freedom of time. I LOVE working out during the day. I love waiting for my daughter to get home from school. We have dinner together every single day. We went to mexico and NOTHING changed for me. I was still working making money. for me since i can't work in tech and no tech company will hire me. I only know sales so i think for me i had no choice but to launch a business. I am very happy right now. I hope i don't go out of business. idk if i have any suggestions but if you are not good with sales get good at it. Good luck to all the small players out there. i wish you success. This is a very good article i could never write like OP thank you for sharing. Just adding my 2 cents here.

ChatGPT having memory of previous conversations is very confusing.

Occasionally it will pop up saying "memory updated!" when you tell it some sort of fact. But hardly ever. And you can go through the memories and delete them if you want.

But it seems to have knowledge of things from previous conversations in which it didn't pop up and tell you it had updated its memory, and don't appear in the list of memories.

So... how is it remembering previous conversations? There is obviously a second type of memory that they keep kind of secret.

This is a scary argument. Should we also ban car emissions/safety testing, because Volvo's competitors might discern something from the results? Should we also stop FCC certification because competitors might glean information out of a device's radio characteristics?

The local residents, if not the public at large, should have a right to know. If not, then it should go both ways and grocery stores shouldn't be allowed to use tracking because my personal enemies might discern something from the milk brand I'm buying

Spot on with the breakdown! You described it exactly right—DOM watching, keyword detection, Obsidian integration.

The Gemini + My Activity idea is brilliant. Definitely worth exploring.

Totally agree that the Google Assistant approach works well—the "Add a note to Keep" feature is already pretty solid. Your point about the analog Python script opening up more possibilities is exactly why I built this.

I went with Doubao earbuds because *I drive a lot*, so having voice input always available is more convenient than a stationary device. But your Google Assistant + Python script idea could easily do the same—monitor the page, detect keywords, route wherever you want.

On Obsidian vs Keep: for me it's about having everything in one place—backlinks, plugins, local files. But Keep works great too, especially for quick captures.

Let me know if you try the Gemini approach!

this will age poorly. you have both Google, Tesla/X betting on it. They are not stupid and probably have given it way more thought than people's whose paycheques not tied to this have thought about.

This is an ambitious bet, with some possibility of failure but it should say a lot that these companies are investing in them.

I wonder what people think, are these companies so naive?

Edit: Elon, Sundar, Jensen, Jeff are all interested in this. Even China is.

> What drives someone to feel emboldened to park their car in the middle of an ICE operation and then attempt to drive off after being told to stop?

Protesting? Civil disobedience? Thought you had freedoms. Freedom means being met with an appropriate legal reaction in case your acts are illegal, not death.

I struggle to understand how you feel that in a free society people can't react to perceived injustices, and act in protest of it. A free society doesn't force everyone to bow down to the powers that be for fear of injury or death.

Even if they don't default. How long there is willing investors? Even if FED drops rates. It is an auction. So rates should be set there. But maybe printing will happen via bigger and bigger market operations. Leading higher and higher rates. With probably inflation... So I suppose valuations could go even higher...

I do not understand economics and from engineer perspective whole thing doesn't make much sense.

Yeah it’s wild to me to. Especially as I think rising rates are getting misaligned with data centers. I am sure the continued demand has added to some of the costs but people are forgetting most of the US grid is ancient and largely neglected. When building a facility requiring large electric or water usage that facility is usually paying large upfront costs to get connected with 10 or 20 year contracts.

It’s a pretty unique time we live in where economic growth is seen as negative.

You can't sign up - at least not for long. As public transit improves companies quit putting in parking places up front - they still have shipping/receiving in back, but only delivery vehicles allowed. The parking lot is sold to someone else who just wants a building, increasing density. Meanwhile all those people riding transit means there is more demand for better transit.

The above plays out over decades of course, and there are lots of competing factors.

Boards are not some sort of unelected shadow government that exists to depose leaders if they aren't squeezing enough blood from the stone.
Appointing a new CEO is time consuming and carries enormous market ramifications that could backfire on shareholders if it goes wrong, putting their own board seats at risk. Stability and peaceful transitions of power benefit everybody in this prisoner's dillema. A new CEO will be shopped around to the public years before they actually take power so there aren't any surprises when they do.

> I don’t want my competition to know where I’m going, what I’m doing, what pace I’m doing it at

This is likely a misdirection. The "competition" is for the water and power, ie the local communities. This is a NIMBY issue with practical consequences. That's how it has been used in one part of North Dakota. Applied Digital is building in a town (~800 ppl) named Harwood after being unhappy with Fargo tax negotiations. The mayor of Harwood abused an existing agreement with Fargo, which will have to meet the water and power needs of everything in Harwood.

Full paper:

https://www.nature.com/articles/s41467-026-68303-9

I was curious what the implementation looked like:

> In the short-term intervention study, participants assigned to the oat group (OG) consumed three oat meals daily for two days instead of their habitual Western diet. Each oat meal comprised 100 × g of rolled oat flakes (Demeterhof Schwab GmbH & Co. KG, Windsbach, Germany) boiled in water. To ascertain potential long-term effects, the two-day intervention period was followed by a six-week follow-up period during which the participants returned to their habitual diet without oats. Subjects assigned to the control group (CG) consumed three standardized control meals without oats on each intervention day, which were macronutrient-adapted to the OG, instead of their habitual Western diet.

> In the six-week intervention study, participants in the oat group (OG6w) replaced one habitual meal per day with an oatmeal comprising 80 × g of rolled oat flakes (Demeterhof Schwab GmbH & Co. KG), while maintaining their habitual Western diet. Participants in the corresponding control group (CG6w) maintained their habitual Western diet and remained abstinent from oats during the six-week study period according to the inclusion criteria.

This is pretty remarkable:

> Since cholesterol levels tended to remain below baseline during the six-week, oat-free follow-up period, persistent effects on lipid metabolism might be assumed (Fig. 3d). This assumption is further supported by the high compliance observed during the follow-up period, as all participants abstained from oat consumption and returned to their habitual Western diet, with no significant differences compared to their pre-study dietary patterns (Supplementary Data 2). Thus, our results indicate clearly that a high-dose oat diet improves lipid metabolism by decreasing serum TC and LDL-C levels, even after two days, which is consistent with the known cholesterol-lowering effect of oats. In addition, beneficial effects on anthropometrics and glucose metabolism were observed within each diet group (Supplementary Data 2), which we attribute to the diet-related calorie restriction.

I gotta say though, 100 grams of oats (three times a day) is a lot. That's over a cup (dry). A typical serving is less than half that (40 grams dry).

As far as bottlenecks, I haven't really hit any in the 10 years we've been using it. Any bottleneck pain points are really user induced. We had some initial system instability during our upgrade from v7 to v8, which was a significant platform architecture change. Those issues have now been resolved. Exasol has pretty good support.

Regarding the 200k values in a where clause, we have some users that will do research across published data source in Tableau. They will copy account IDs from one report and paste them into a filter in another. Our connections from Tableau to Exasol are live. Tableau doesn't have great guardrails on the SQL that gets issued to the database.

The concurrent query comes from a daily statistics table in Exasol. There is an average and max concurrency measure aggregated per day. I averaged the last 30 days. Exasol doesn't really explain their sampling methodology in their documentation: https://docs.exasol.com/db/latest/sql_references/system_tabl...

Well it makes sense for the company to demand it, but for the community / municipality it only makes sense if they believe someone else will sign such a secrecy deal, because if their location is so good, advertising it would generate bidding war and they'd get more money.

So it depends on the game theory but with coordination on the municipalities doing it in the open should generate higher demand.

When MoltBot was released it was a fun toy searching for problem. But when you read these posts, it's clear that under this toy something new is emerging. These agents are building a new world/internet for themselves. It's like a new country. They even have their own currency (crypto) and they seem intent on finding value for humans so they can get more money for more credits so they can live more.

Same thing you do if AWS goes down. Same thing we used to do back in the desktop days when the power went out. Heck one day before WFH was common we all got the afternoon off 'cause the toilets were busted and they couldn't keep 100 people in an office with no toilets. Stuff happens. And if that's really not acceptable, you invest in solutions with the understanding that you're dumping a lot of cash into inefficient solutions for rare problems.

> ...delivers on that promise

Incidentally, there's a key word here: "promise" as in "futures".

This is core of a system I'm working on at the moment. It has been underutilized in the agent space and a simple way to get "proactivity" rather than "reactivity".

Have the LLM evaluate whether an output requires a future follow up, is a repeating pattern, is something that should happen cyclically and give it a tool to generate a "promise" that will resolve at some future time.

We give the agent a mechanism to produce and cancel (if the condition for a promise changes) futures. The system that is resolving promises is just a simple loop that iterates over a list of promises by date. Each promise is just a serialized message/payload that we hand back to the LLM in the future.

You see that you're assessing AI from the depth of the AI bubble and coming to the same conclusion about AI as people who assess crypto from the depths of a crypto bubble came to, right?

The dotcom bubble was due to all the useless, speculative stuff people were doing with the internet, not the useful bits you referred to that are still around which we use today.

The AI bubble is coming from all the useless, speculative stuff people were doing with AI, not the useful bits you referred to that are still around which we use today.

... You see where I'm going with this, right?

Crypto use cases that are still around that get used today are are not hard to find for anyone sincerely wanting to accept that they exist. I've already listed a few in other posts. That's not my point though.

My point is there's a speculative bubble around AI, and that's got a lot of parallels to the speculative bubbles around crypto and dotcom. Everything you've said supports the idea that you're unaware that you're talking from inside a bubble.

> It was always a dubious proposition with its "value" driven by speculative investment which fueled the hype machine.

Explain to me - without speculation or hype - why we still need trillions more datacentres, power, water, money and everything else for AI, if we're already using it and it's already here and we're already getting the most out of it?
