This is a very frivolous argument against solar farms given the amount of noise and other pollution emanating from regular farms.

Farm-scale irrigation is not silent.

Crop Dusters are not silent.

Combines and other tractors are not silent.

Burning fields are both not silent and release a tremendous amount of sooty smoke that spreads far beyond the boundaries of a farm.

Farms make a lot of noise.

Yeah, in Oconto county Wisconsin, residents are all up in arms about a solar farm going up. It's the poorest county in the state and would bring in much needed money. The arguments against it are "this destroys farmland", "who will clean the snow off of it in winter", "I don't like how it looks", "static electricity will kill the crops around it", "it will raise the temperature of the surrounding area", "you can't recycle fiberglass so it's bad", etc.

A matrix is just a grid of numbers.

A lot of areas use use grid of numbers. And matrix theory actually incorporates every area that uses grids of numbers, and every rule in those areas.

For example the simplest difficult thing in matrix theory, matrix multiplication is an example for this IMO. It looks really weird in the context of grid of numbers, and its properties seem incidental, and the proofs are complicated. But matrix multiplication is really simple and natural in the context of linear transformations between vector spaces.

I assume that this app is not a mailing app, its an app to control your fastmail service, which includes email, file storage, webhosting, various dns controls, notes, contacts, billing etc. They already contributed JMAP. It would be impossible for them to get all of those features into k-mail - k-mail wouldn't want them.

And packaging the app in electron is relatively easy and a nice convenience for some users.

The issue with this prize isn't that economics is not a real science. Nobel prizes are primarily vulgarization and communication tools, and as such are inhenrently political. The Sveriges Riksbank is piggy-backing off the popularity of Nobel Prizes to advocate for a certain vision (their vision) of economic orthodoxy. It is overwhelmingly awarded to white western men, who, more relevantly, all share an anglocentric neoliberalist vision of economics. This, I hope, we are allowed to take issue with.

EDIT: apparently not. I would rather you explain to me why than downvote mindlessly.
by jacquesm | 2025-10-13 13:20:08+00:00
That's a tiny article, but it does contain an interesting passage: "for having identified the prerequisites for sustained growth through technological progress" which is the core of the reason the prize was awarded. I find it interesting to see technological progress so tightly coupled to sustained growth and I wonder if the implication is that growth will stop when technological progress stagnates. Is there any proof to that effect?

Cash is safe. Gold is at a record high for a reason. There are still some companies worth owning.

In general, the thing to look at is the level of liquidity in the market. The liquidity is there, but the problem is there's too much uncertainty for many companies to be able/willing to invest, so it mimics a lack of liquidity.

Great comment :)

I used to be pretty into junk bonds during my MBA (I don't do this at all professionally, so YMMV with my commentary here), and I think, as usual, a lot of context would help with understanding what this could mean, which ajross described. In the most simple terms, as other have also mentioned, it's basically non-investment grade companies (and there are a lot of em - you'd be surprised at the names on the list) now have to pay more for money. This could mean that investors are worried and want more compensation for risk, which means that the reality of the economy is shakier. OTOH, it could mean that investors are being more realistic, and not letting risky companies just have cheaper money to make value destructive decisions could be a good sign of sanity in the markets, and thus (in theory) the economy. It's hard to know with a simple headline or article. Even if you dig into all the numbers and do all the reading, it's still hard to know since the world is really complex.

I look at this as a single data point amongst many re: how I end up assessing my feelings about the economy. Truth be told, I'm probably more concerned about what lots of news outlets are discussing - all the AI capex spend. Apparently there's more financing being negotiated with fewer restrictions on the debt, which tends to be a really bad sign of a bubble.
by NoboruWataya | 2025-10-13 13:20:44+00:00
It's difficult to say with any certainty what it means for the general economy, but your understanding of what this is saying about the junk bonds themselves is basically correct.

Whether it leads to a lot of defaults depends on a lot of factors. A sell-off in bonds can really screw a company if it happens to have immediate financing needs at the time, but otherwise it doesn't really impact the company directly. Junk bonds are, as the name suggests, known to be risky assets, so they are generally the first to be sold when things get a bit choppy and investors decide to sit the market out for a bit to see how events unfold.

This seems like it is pretty clearly a response to the recent tariff escalation so, as with all the other tariff announcements, it will depend on whether the recent announcement is a change in policy or another negotiating tactic.

You also see a lot of headlines like "worst losses in six months!" "biggest sell-off since September!" but these are fairly short timeframes and a lot of this is just trying to make some news out of the usual market noise.

> We can take a definition of a rose from a neural network that recognizes what a rose is

Can we? That just shifts the problem to building such a NN.

I think it would already be pretty tricky to get a decent sized panel of humans to agree on what a "rose" is. Do rose-shaped but yellow flowers count? How about those genetically altered thornless ones? How about perfectly imitatations that are made of plastic? Images of roses? The flowers from the list at https://www.epicgardening.com/rose-lookalikes/?

And of course there's the problem of getting a NN to recognise just roses. The mythical neural network with 0% error rate is exceptionally rare and usually not very useful for real world applications. I very much doubt humanity could build a neural network that perfectly recognises roses and only roses.

That limits to only 2 selections. If I keep pressing Alt + S, it does not select multiple instances of the first selection.

Also, I can't immediately start typing like in Sublime to replace the content. For example:

"test/filenameA.c"

"test/filenameB.c"

"test/filenameC.c"

"test/filenameD.c"

If I select test/ with the cursor, then A-s, it won't select 3 and 4. If I do this, however:

C-d = ["search_selection", "extend_search_next"]

It does select test/, in all 4 lines, but I can't immediately type "blah" to change test to blah.

The physical world is within regulated frameworks though. There is no regulatory body in charge of the Ethereum blockchain.

The prosecution is alleging that there was a "promise" to the victim, which would let the transaction breach the boundaries of the crypto universe and be classified as real world fraud between two individual parties, but I just don't see how there was any sort of "promise" made here. First of all, they traded against an automated trading bot. Second, a bid or ask and market liquidity is not a "promise". I trade for a living and market makers suddenly pull liquidity all the time when it suits them, on millisecond time-frames. Granted, what the brothers did is essentially "spoofing" or posting bids and asks with the intent to move markets, so the question here to me boils down to is crypto spoofing illegal or not. Perhaps that depends on the jurisdiction/and or decentralized nature of the exchange that they were posting the offers on. I would think that if they can get charged for this then the majority of trading on thousands of "shitcoins" is outright illegal activity by extension though.

On a much more simplistic level, if you're coding up in ethereum arbitrage bot, and it makes a bad high frequency arb trade... tough luck? I was under the impression that this was sort of the point of crypto markets, to escape regulations and be a freeform, decentralized trading venue.

The first time I learned it was from a book by LaMothe in the 90s and it starts with your demonstration of 3D matrix transforms, then goes "ha! gimbal lock" then shows 4D transforms and the extension to projection transforms, and from there you just have an abstraction of your world coordinate transform and your camera transform(s) and most everything else becomes vectors. I think it's probably the best way to teach it, with some 2D work leading into it as you suggest. It also sets up well for how most modern game dev platforms deal with coordinates.

I never store anything personal or important on the C:\drive. I treat it as disposable. Instead, I create a secondary drive (like Z:\) and store all important work there.

This way, I always know that Z:\ is the only drive I need to back up, while C:\ remains clean and expendable. Even my Dropbox folder lives on the secondary drive.

Kind of, with the difference that it has been in production since 2015 on Solaris SPARC systems, granted they aren't as widespread as they once were.

Sometimes the perfect is enemy from good, none of the memory tagging solutions has achieved mainstream widespread adoption outside iDevices.

Google apparently doesn't want to anger Android OEMs demanding it to be required by Android, thus it remains a Pixel only feature.

CHERI and OMA are going to still take years for mainstream adoption if ever comes to it.

I had hopes for whatever Microsoft was doing in CHERIoT to eventually come to Windows in some fashion, but best it has happened seems to be the adoption of Pluton in CoPilot+ PC, which anyway serves a different purpose.

I am really struggling to figure out what this is or how it provides value.

Edit:

This discussion isn't exactly what I was hoping for. I was looking for ways to better highlight the features or value proposition of this site. Not defenestrate it altogether.

E.g.: A simple modal that says "Welcome to SQLite Online! You can <core value proposition> with this tool." would have radically altered my initial perception.
by zamadatix | 2025-10-13 13:23:19+00:00
Same. Part of the background info on this is PSUs are usually most efficient at (or just under) 50% load. They are also more efficient at 240 V than 120 V, if you have the circuit. So the real efficiency can end up varying significantly, depending how you use it. The efficiency is not usually much to write home about in terms of your electric bill, but it does help drive the ability for the PSU to cool itself passively.

Too big to fail, nation state edition?

But yeah. I looked at how my pension funds are invested, and it's like 70% in the US. Even more than the sovereign wealth fund, which is apparently around 50% (if a quick AI search can be trusted).

Thing is, I'm not sure I will like the world where OpenAI and co. are as wildly successful as their valuation suggests either. So maybe I should invest in them, so that if it comes to pass, I at least have money?

oh spare me. Social sciences are inherently political. They've always been political and they will always be political. Denying merely makes it worse. that's how you end up with the racialist anthropology of the 19th and early 20th centuries.

This is not a theory (or is one, but false) according to Popper as far as I understand, because the only way to check understanding that I know of is to ask questions, and LLMs passes it. So in order to satisfy falsifiability another test must be devised.

> I can't even fathom what the build system is doing in order to require this amount of storage.

A large number of 17 year old repositories, prebuilt toolchains, and the fact that you otherwise have every little bit of source code, intermediary results, and output to create a full operating system all in the same place.

As for the memory, the very first step (that basically already is the benchmark for the most memory usage) is loading the entire build tree and generating build steps. Yes, that takes 32GB of RAM, if not 64GB nowadays.

Bond spreads widening reflect lenders' fear that borrowers will default. So what this means is that on average people think that the lowest class of borrowers (junk) are going to struggle to repay. That means it is more expensive for them to borrow, which is going to generally discourage those companies from investing in projects or starting new things which require debt finance. So you would expect the knock-on effect to be less activity in general.
Show HN: ch, a terminal tool to highlight specific words in your command output
by dtonon | 2025-10-13 13:24:48+00:00
I needed to take a look at some live logs and quickly analyze some old ones, but I couldn't find anything effective to highlight terms, except for esoteric sed and awk commands. So I built ch - Colored Highlighter - a simple terminal tool to highlight specific words in your command output with colors. Perfect for tailing logs, debugging, and making command output more readable.

Sparkfun page suggests one can do some of these adjustments via software too:

On memory unsafe Rust: It tends to come crashing down when unsafe is necessary, for both reasoning about unsafe is harder than in C++, and the rules for unsafe in Rust is an active area of research. Do you know all the intricate rules of unsafe (not all which have been defined), can you reliably predict what is safe and what is not without using Miri? Miri that cannot test all? Are you an expert on aliasing and pinning? Can you describe what tree borrows are?

On doubly linked lists: Sorry, but to implement a doubly linked list in Rust well, you have to go through trials and tribulations. A whole book was written about an epic of implementing doubly linked lists in Rust: https://rust-unofficial.github.io/too-many-lists/ . And if all that is required for a data structure as simple as a doubly linked list, what will then be required for some of the more complex data structures?

I'll add the obligatory Dilbert take: https://verisoeconomica.wordpress.com/2022/10/10/the-2022-no...

Sure, it's paid by the Swedish central bank instead of the Nobel foundation, and it wasn't established by Alfred Nobel himself. Nobody cares. Value of such awards depends entirely on peer recognition, not on who pays or what exact labels they carry. Selection for economics is done by the Royal Swedish Academy of Sciences, like the other science awards.

No need to degrade people, if anything the highest class with hop on the AI train. Why trust an expensive human when an LLM will give you unlimited "advice" ?

LLMs can serve as a fall guy, but what's the old IBM quote. Something like a computer will never be responsible for an executive decision.

Then again LLMS making stupid mistakes is the only thing keeping most of us employed
Show HN: Terminal-First Documentation Service
by mkei29 | 2025-10-13 13:26:31+00:00
Hi, let me introduce the document service I've been developing for about a year.

There are many document hosting services, but few prioritize interaction between developers. I think most documentation services target general readers and aren't designed to be used by developers themselves.

dodo-doc is a documentation hosting service built for myself and fellow software engineers. It supports the following functionalities that other documentation services don't have:

Strong CLI Tool I'm aiming for a documentation service that can be interactively manipulated from the terminal. You can not only upload but also search and open docs directly from the terminal. We also have experimental support for MCP.

CI Affinity Don't you want to preview documents on CI? I do. You can easily set up deploy and preview flows on GitHub Actions.

Private Use Other documentation tools may have this feature too. But it's REQUIRED for me because I write journals in git. Therefore, dodo-doc supports private documents out of the box.

It's easy to set up, so I'd love for you to give it a try. I'm looking forward to your feedback!
by robenkleene | 2025-10-13 13:26:35+00:00
Thanks yeah this is a good example of why I prefer the simpler interface for `rg` and `fd`. Those examples would actually be fine if this were something only did once in awhile (or in a script). But I search from the command line many times per day when I'm working, so I prefer a more streamlined interface.

For the record, I think `git grep` is probably the best builtin solution to the problem I gave, but personally I don't know off-hand how to only search for files matching a glob and to use the current directory rather than the repository root with `git grep` (both of which are must haves for me). I'd also need to learn those same commands for different source control systems besides git (I use one other VCS regularly).

Economist here…

An unexpected (to me!) prize but definitely a good one.

What’s notable is that mokyr’s research is very, very accessible to a layman. You can read his books and understand them nearly perfectly without needing substantial technical background. (Of course there’s a huge existing literature in economics and history he’s engaging with which you won’t know, but I’m not an economic historian either so a lot of it is unfamiliar to me too.). Try it! Hopefully you learn something.

Also the committee always releases a good non-technical summary of the laureates work and an even better “more technical” summary. You can start there for an overview.

As for the point which will be raised endlessly here that this is “not a real Nobel” - whatever. No one in the economics profession cares. Alfred Nobel doesn’t have a monopoly on prizes or priority to decide which fields are worth recognizing. It’s our highest prestige prize. Call it what you want.

Isn't US made equipment facing the headwinds of the US being anti-solar. It seems more like the US shot itself in the foot by letting the Chinese get the lead on this technology. And by subsidizing, and maybe regulating buying US, we could support our domestic industry.

Seems like all over the place we are giving up and letting China win the technology race. Robots, cars, solar, all the future tech is in trouble.

Why do people persist in repeating this dumb meme? Tyler Cowen, who should really know better, does it too. To be profitable shorting, you have to not only be right about the direction of the market but you have to time it precisely. Shorting is not 'I think the market is going to decline at some point in the future', or else we'd all do it.

You're borrowing to short, and your broker can call your loan at any time for any reason or no reason at all, including 'our risk algos felt nervous this afternoon'. If you try to short a stock or ETF and the market surges in a dead cat bounce before declining, you get completely wiped out even if you're going to be eventually right
