There's currently no technological path for fusion to be cheaper than fission. It would require a technological breakthrough that we have not yet imagined.

And already, solar plus storage is cheaper than new nuclear. And solar and storage are getting cheaper at a tremendous rate.

It's hard to imagine a scenario where fusion could ever catch up to solar and storage technology. It may be useful in places with poor solar resources, like fission is now, but that's a very very long time from now.

On my laptop, I edit the wallpapers to include a black bar at the top, so I rarely notice the notch. Eg: https://celsoazevedo.com/files/2025/macos-bar.png

Got the idea from the Top Notch app, which no longer seems to work: https://topnotch.app/
Looking for an influencer to help with agentic e-commerce app for fashion
by kuma0177 | 2025-10-23 20:03:01+00:00
I am building a genAI powered virtual try on app and my app is about to launch. Since I am bootstrapped and have built the app on my own, I don't have crazy performance marketing budget to help cold start and get my initial set of users. So I have been thinking of looking for a fast growing fashion influencer who would be interested in being a co founder of my app in return for 10-15% equity stake in the app and helping me with distribution.

I don't think it is very "magic".

The VFS gets you a few main benefits.

1. You can lazy download and checkout data as you need it. Assuming your build system is sufficiently realized to hide the latency this will save a lot of time as long as accessed data is significantly less then used data (say <80%).

2. You don't need to scan the filesystem to see what has changed. So things like commits, status checks and even builds checking for changes can target just what has actually changed.

Neither of these are particularly complex. The hardest part is integrating with the VCS and build system to take advantage of the change tracking. Git has some support for this (see fsmonitor) build I'm not aware of any build systems that do. (But you still get a lot of benefits without that.)

Hi everyone, I have developed a couple of demos to show case prototypes where an AI-driven framework can be used for data governance and assessing discrepancies in geodata for Longhaul networks. This uses a distilled promptly and a hierarchy of truth to propagate through the tooling and systems. Please share your feedback on areas of improvement and what other demo you would want to see.

That rubber duck is a valid workflow. Keep iterating at how you want to explain something until the LLM can echo back (and expand upon) whatever the hell you are trying to get out of your head.

Sometimes I’ll do five or six edits to a single prompt to get the LLM to echo back something that sounds right. That refinement really helps clarify my thinking.

…it’s also dangerous if you aren’t careful because you are basically trying to get the model to agree with you and go along with whatever you are saying. Gotta be careful to not let the model jerk you off too hard!

It makes so little sense that it's hard to comment.

> Unlike GPT-3, which at least attempted arithmetic internally (and often failed), o1 explicitly delegates computation to external tools.

How is it a bad thing? Does the author really believe this is a bad thing?

Even if we believe tech bros' most wild claim - AGI is around the corner - I still don't know why calling external tools makes an AGI less AGI.

If you ask Terence Tao what 113256289421x89831475287 is I'm quite sure he'd "call external tools." Does it make him less a mathematician?

Plus, this is not what people call "reasoning." The title:

> Reasoning Is Not Model Improvement

The content:

> (opening with how o1 is calling external tools for arithmetic)

...anyway, whatever. I guess it's a Cunningham's Law thing. Otherwise it's a bit puzzling why someone knows nothing about a topic had to write an article to make everyone know how clueless they are.

Let's look at the marketplace for aviation piston engines. We still see the Lycoming IO360 [1] and its variants installed in aircraft today. For reference it was first produced in 1955. That's >70 year old tech which produces ~200 hp depending on the version. It's used in myriad designs because it's certified and well known. It weighs around 260 lbs. (very hand wavy calculation...) that means we are looking at roughly .76 hp/lb or 1.28 kW/kg. Compare that to 59kW/kg of the article.

Right now, the engine is generally the most expensive as well as the heaviest component in GA aircraft. If you are developing a new airplane, you are often choosing a motor to build the craft around. You would be a fool to choose something that is not tested because (almost) nobody wants to fly a new plane with a new motor. I'm guessing that the cost of one of these axial flux motors is well below $70k. I'll guess $2k... just for ease of numbers.

Our motor is now 46x lighter/hp and 1/35 of the cost. This means we have a lot more flexibility in our aircraft design and our budget for materials/components has gone up, or our market has gotten wider. The biggest hurdle now is to overcome the "unknown engine" which is possible when the exact motor has been mass-produced and mass-used in other sectors. By using this and not painting your design into a corner by relying on the absolute lightest motor you can get, you leave room for future designs in the same space. ie: you have set yourself up to produce the next Cessna 172.

There are additional reasons to want a motor that is 200 hp or less which are written in FARs in the US and copied by other countries. Also, wanting a motor that is more than 200 hp is desirable for other use-cases. By having one motor that can fill both spaces you now have (waves hands) twice the reputation building power.

Of course, there are other technical considerations such as energy storage/weight but the field is so wide that a book could be written on making comparisons. The technical landscape is also actively changing.

Good write up, and the author certainly seems to really know their stuff.

I still like using Next, though. Some nitpicks:

> Elements that could change need to be inside a client component, but data fetching cannot happen on the client components, even during SSR on the backend. This results in awkwardly small server components that only do data fetching and then have a client component that contains a mostly-static version of the page

That's one way to do it.

I like flipping it, though - most of the page is a server component, with awkwardly small client components that sprinkle in just enough JS for things that need interactivity (such as optimistic updates from the above quote).

> Since the App Router starts every page as a server component, with (ideally) small areas of interactivity, a navigation to a new page has to fetch the Next.js server, regardless of what data the client already has available!

This is true, and something that Remix v1/v2 did a lot better than Next.

The Raspberry Pi isn't supported as a sensor right now, but it should be able to act as the device running TOMMY. As long as it has Docker.

The interference from running TOMMY is quite low. And if ESP32-C6 (2.4Ghz Wi-Fi 6) or ESP32-C5 (5Ghz) is used as sensors, the interference is negligible.

Cursor’s implementation of plan mode works better for me simply because it’s an editable markdown file. Claude code seems to really want to be the driver and you be the copilot. I really dislike that relationship and vastly prefer a workflow that lets me edit the LLM output rather than have it generate some plan and then piss away time and tokens fighting the model so it updates the plan how I want it. With cursor I just edit it myself and then edit its output super easy.

Kaitai Struct is really great. I've used it several times over the years to quickly pull in a parser that I'd otherwise have to hand-roll (and almost certainly get subtly wrong).

Their reference parsers for Mach-O and DER work quite nicely in abi3audit[1].

Idk how to fix this, but the problem with interviews by rank and file employees is they have to prioritize standardization and objectivity over finding brilliant applicants. It only makes sure the applicant knows how to code rather than lying on his/her resume. I think Jobs said something like, B players will hire B and C players.

When I interviewed at a smaller company, someone high up interviewed me last. I passed everything on paper afaik, but he didn't think I was the right person for some reason. Which is fine for a small company.

> They get to counter a point they think is wrong

They didn't counter OP's claim, though. OP is essentially saying that software other than open-source can be trustworthy and the supposed counter-claim is that open-source software is more trustworthy. Regardless of that being true or false, it's not a counter to the claim that closed-source software can also be trustworthy.

Wrong on every count, basically.

1. You can enable or disable tool use in most APIs. Generally, tools such as web search and Python interpreter give models an edge. The same is true for humans, so, no surprise. At the frontier, model performance keeps climbing - both with tool use enabled and with it disabled.

2. Model capabilities keep improving. Frontier models of today are both more capable at their peak, and pack more punch for their weight, figuratively and literally. Capability per trained model weight and capability per unit of inference compute are both rising. This is reflected directly in model pricing - "GPT-4 level of performance" is getting cheaper over time.

3. We're 3 years into the AI revolution. If I had ten bucks for every "breakthrough new architecture idea" I've seen in a meanwhile, I'd be able to buy a full GB200 NVL72 with that.

As a rule: those "breakthroughs" aren't that. At best, they offer some incremental or area-specific improvements that could find their way into frontier models eventually. Think +4% performance across the board, or +30% to usable context length for the same amount of inference memory/compute, or a full generational leap but only in challenging image understanding tasks. There are some promising hybrid approaches, but none that do away with "autoregressive transformer with attention" altogether. So if you want a shiny new architecture to appear out of nowhere and bail you out of transformer woes? Prepare to be disappointed.

Personally speaking, having just bought an Ioniq 5 and installing solar at home what I see as the near future improvement is adding V2L functionality, which I can hook up to the generator input of my solar inverter, essentially adding another 60kWh buffer to my grid storage.

Considering how expensive residential batteries are and how quickly EVs depreciate, I think soon it'll be cheaper to get a used EV as a cheap source of cells that accidentally happens to be able to drive itself around.

Imo V2G, and V2H is unnecessary and add too much complication, I think for the future, solar inverters already have the necessary hardware and certifications to be able to take power and safely connect to the grid - something that requires different hardware and standards compliance in basically every country (yes even within the EU).

I wonder if civil forfeiture will work against Trump once he's out of office. Trump's net worth before becoming President was under US$1 billion. Now it's over 6 billion. A civil claim for the difference based on the Emoluments Acts.

"The Foreign Emoluments Clause bars the president and other federal officials from accepting “any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince, or foreign State” without the consent of Congress. It reflects the framers’ desire to prevent federal officials from succumbing to foreign influence.

The Domestic Emoluments Clause provides for the president to receive a fixed salary and bars him from receiving “any other Emolument from the United States, or any of them.” It was designed to insulate the president against undo pressure from Congress or any individual state."

Prius Plugin 2015 (last year of that model) - full charge/discharge at least 3-4 times a week, currently still a bit more than 80% of capacity (granted the battery seems somewhat overbuilt, yet it is normally does 10-15C which is much tougher mode than in a pure EV where 2-3C is usually enough and only high-end Teslas and the likes would do 5-6C). There has been large continuous improvement in lithium batteries over the last couple decades.

Oh, that smell of molten keyboard plastic, those yellow spots burned into a display with its own heat exhaust, those laser-machined loudspeaker holes next to keyboard, all filled with grime! How I miss that time on a Macbook, with all the chords you have to press whenever you need a Home or End button to edit the line! Not to mention the power button right next to backspace.

It's so rewarding when its charger dies in a month, and you feel superior to your colleague, whose vintage 6 months old charging cable with none of that extraneous rubber next to the connector catches fire along with your office. What a time to be alive!

The best part is the motherboard produced in a way to fail due to moisture in a couple of years, with all the uncoated copper, with 0.1mm pitch debugging ports that short-circuit due to a single hair, and the whole Louis Rossmann's youtube worth of other hardware features meant to remind you to buy a new Apple laptop every couple of years. How would you otherwise be able to change the whole laptop without all the walls around repair manuals and parts? You just absolutely have to love the fact even transplanting chips from other laptops won't help due to all the overlapping hardware DRMs.

I'll go plug the cable into the bottom of my wireless Apple mouse, and remind myself of all the best times I had with Apple's hardware. It really rocks.

The only path to staying on the SaNoQ is having a CEO who prioritizes quality, to the extent that they'll spend time dogfooding product and gripe at developers / engineers / designers / leaders who fall short.

Either everyone is worried about the consequences of failing to produce high quality work (including at the VP level, given they can allocate additional time/resources for feature baking) or optimizing whatever OKR/KPI the CEO is on about this quarter becomes a more reliable career move.

And once that happens (spiced with scale), the company is lost in the Forest of Trying to Design Effective OKRs.

We _are_ using subject DNs for linking certs to their issuers, but though that's "free-form", we don't parse them, we only check for equality.

It's funny you just mentioned this because we just learned a few weeks ago in physiology about Henneman's Size Principle: that the somatic nervous system recruits smaller skeletal muscle motor units (1) followed by larger motor units as the amount of force needed increases.

That would make resistance training by rowing in water better fit than some magnetic resistance machine based on what you described. Air also has same property like any other fluid, your average big body of water has enough viscosity for this property to matter at speeds we don't need cybernetics and Tommy John's surgery to survive.

(1) A motor unit is just all the muscle fibers controlled by 1 motor neuron. With this single source of signals, all those muscle fibers respond the same way.

>One thing that came up was a very candid comment about how "we should be able to tell someone 'that is just stupid'

You can tell someone their idea is substandard without inferring their stupid, which is generally taken to be an insult. Tact in communication does matter. I don't think anyone needs to say "that is just stupid" to get a point across.

I've had plenty of tough conversations with colleagues where it was paramount to filter through ideas, and determining viable ones was really important. Not once did anyone have to punch at someone's intelligence to make the point. Even the simple "Thats a bad idea" is better than that.

>whenever the situation warrants it

Which will of course be up to interpretation by just about everyone. Thats the problem with so called "honest"[0] conversation. By using better language you can avoid this problem entirely without demeaning someone. Communication is a skill that be learned.

>The Linux kernel would be absolutely trash if Linus were not allowed to be Linus. Some contexts do and must require a high level of expertise before you can collaborate properly in them.

Linus took a sabbatical in 2018 to work on his communication and lack of emotional empathy. He's had to make changes or he absolutely risked losing the respect of his peers and others he respected. He has worked on improving his communication.

To follow Linus as an example, would be to work on communication and emotional empathy. Not disregard your peers.

Apples attention to detail has always been skin deep. I remember reading blog posts 20 years ago about how some apps followed Apples standards design and others didn’t follow their design standards at all.

In the 90s Apple was in worse shape. They couldn’t even compete with Windows 9x for stability. There were memes about how MacOS needed just as many reformats as Windows 98.

The problem isn’t Apples attention to detail, it’s that people hold Apple to a higher standard. But in reality they’re just as fallible as every other software company.

>First time it happens, there will be an explosion of protests.

Why do you believe this? In the US, cops will cower outside of a school with an armed gunman actively murdering children, forcibly detain parents who wish to go in if the cops wont, and then re-elect everyone involved

In the US, an entire segment of the population will send you death threats claiming you are part of some grand (democrat of course) conspiracy for the crime of being a victim of a school shooting. After every school shooting, republican lawmakers wear an AR-15 pin to work the next day to ensure you know who they care about.

Over 50% of the country blamed the protesting students at Kent state for daring to be murdered by the national guard.

Cops can shoot people in broad daylight, in the back, with no justification, or reasonable cause, or can even barge into entirely the wrong house and open fire on homeowners exercising their basic right to protect themselves from strangers invading their homes, and as long as the people who die are mostly black, half the country will spout crap like "They died from drugs" or "they once sold a cigarette" or "he stole skittles" or "they looked at my wife wrong" while the cops take selfies reenacting the murder for laughs and talk about how terrified they are by BS "training" that makes them treat every stranger as a wanted murderer armed to the teeth. The leading cause of death for cops is still like heart disease of course.

Trump sent unmarked forces to Portland and abducted people off the street into unmarked vans and I think we still don't really know what happened there? He was re-elected.
