There's nothing sensational about it, and I'm disappointed that you cannot see this thing for what it is. Ask people among your relatives who own real estate and you will realize that a lot of them mortgaged their real estate to pay for new cars, vacations, investment in a business, kid's education.

The money is paid back over a long period of time, while the currency depreciates in value and the real estate appreciates in value. The amount of people who have made a fortune through real estate appreciation probably outnumber by a factor of 10 to 1 the amount of people who made a fortune by business or a working career.

If I purchase shares in a company and then sit and do nothing, and the valuation increases by 10 times, then have I made money or not? I can sell the shares or I can mortgage the shares by borrowing against their value. Should that value increase be taxed?

The irony of progress indicators like the sunburst here is that everything okd is new again

In the Before Times your UNIX would have a progress bar that was basically the same spinning icon: overwrite - \ | / - \ | / in the same character location in quick succession.

It was as useless then as the spinning sunburst is now.

The linear indicator provides two bits of information: that something is happening, and that progress is being made towards completion. The sunburst only provides one.

> In the coming months, Amtrak will be operating both the current Acela equipment and the NextGen Acela trains as the new trains transition into the fleet.

I do hope that at the time of booking they make it clear which Acela it is. Airlines do this: they usually mention the type of plane while booking. I might just do a trip on the new Acela to experience the train.

I think maybe it is ragebait, (maybe unintentional). In particular, it is phrased as an argument against email threads in general, but then we have:

> Innocently, you click into the top email. The only text is "[Your Name] see below."

IMO this is bad behavior and it is right to push back. The person forwarding the email should provide context: what’s going on and why am I being included, what’s expected of me here?

If I’m just told to “See Below,” ok, I’ll see it. I’ll interpret that at an FYI for me, no deliverables requested (of course, an FYI might include the information about the needs of somebody who’s ass I need to kiss).

—

The ragebaity thing is to have a general rant against something pretty normal, but to only have an example based on obviously bad behavior. Is that Motte-and-bailey? Not sure, but it doesn’t pass my sniff test.

How does that work? Mortgaging is selling a portion (in an abstract sense) of a house for cash, with an obligation to buy that portion back in installments.

So parent has mortgaged their 100k house for a million - now what? How do they get out of their obligation to repay the mortgage - that is, buy the house back again for at least a million - without incurring penalties?

If there weren't repercussions for defaulting on mortgage payments, anyone could just trick lenders into buying their house immediately.

This mechanism sounds worth it.

So many times on X11 do I type some chat message, and then some popup from another program comes up, which I accidentally confirm by my typing containing a space which presses the confirmation button, and I don't even know what the popup was.

Or my password being typed in a popup.

I once patched some code into i3 to prevent this for myself, but it wasn't a clean solution.

> You are sadly completely missing the point of ever-self-improving automation. Just also use the commit history.

I don't think you understand the issue you're commenting on.

It's irrelevant whether you can inject commit history in a prompt.

The whole point is that today's support for coding assistants does not support this source of data, whereas comments in source files and even README.md and markdown files in ./docs are supported out of the box.

If you rely on commit history to provide context to your team members, once they start using LLMs this context is completely ignored and omitted from any output. This means you've been providing context that's useles and doesn't have any impact on future changes.

If you actually want to help the project, you need to pay attention on whether your contributions are impactful. Dumping comments into what amounts to /dev/null has no impact whatsoever. Requiring your team to go way out of their way to include in each prompt extra context from a weird source that may or may not be relevant is a sure way to ensure no one uses it.

The post mentions the AI boom boosting the numbers. From Fortune[1]: "Analyst estimates from Renaissance Macro Research indicate that so far in 2025, the dollar value contributed to GDP growth by AI data center expenditure surpassed the total impact from all U.S. consumer spending"

That is worrying as that spending is constrained to a small sector that concentrates and solidifies a lot of wealth with diluted "trickle down" effects. If/when the AI industry corrects there will be a significant impact on the US economy & stock market, which I think will have a bigger negative effect on the "person in the street" than any possible positive effect from the current high spending on AI technology.

I don’t think it’s necessarily clear what they meant because “en masse” has been pretty thoroughly borrowed into English as a singular phrase, as have many other French words and phrases. To then literally translate that borrowed phrase back into English is just confusing because those English words are not correct in that context (while the borrowed French phrase is).

For what it’s worth I definitely did a double take and had to re-read the sentence because I was not expecting those words there.

> Unless you are running some really complicated globally distributed backend your roundtrip will always be higher than 80ms for all users outside your immediate geographical area.

Many of us don't have to worry about this. My entire country is within 25ms RTT of an in-country server. I can include a dozen more countries within an 80ms RTT. Lots of businesses focus just on their country and that's profitable enough, so for them they never have to think about higher RTTs.

> That's the reasoning we're applying if we tax unrealized gains on stocks (or any other asset). We take what the highest bidder is willing to pay for some tiny percentage of an asset, and assume that means everyone else could get the same price, yielding these theoretical valuations that have no bearing on reality.

We take what the highest bidder is willing to pay, as well as what the lowest seller is willing to sell for. So it's a completely fair way of fixing the value. If you think the price is too high, then why aren't other sellers rushing to sell for the same? If you think the price is too low, then why aren't other buyers rushing to buy?
Show HN: Markdown-UI, interactive UI inside Markdown for LLMs
by yaoke259 | 2025-08-08 12:38:11+00:00
Currently LLMs can only stream raw text and users can only respond in raw text.

This open, MIT license standard allows LLMs to send simple, secure, JSON code blocks which get rendered into widgets.

The widgets can emit events, which your application can capture and send back as text to the LLM.

Currently I've coded a proof of concept using an extended marked.js parser and Svelte 5 renderer, but any parser or renderer (Remark, React etc.) can support this standard.

Please let me know what you think!

One example of a profile that lives on a different PDS ("AT Protocol Personal Data Server") than the default one: https://bsky.app/profile/mackuba.eu

If you look in the bottom left of https://clearsky.app/mackuba.eu/history, it shows:

If you go to that URL, you'll see the landing page for the atproto PDS software.

Edit: Ah, and seems Kuba is hosting a directory of profiles using their own PDS as well, lots of examples over there: https://blue.mackuba.eu/directory/pdses

Biggest one right now (excluding the default one) seems to be atproto.brid.gy, which has 40393 accounts.

> Barbero et al. have shown that attention sinks serve as "pressure valves" preventing what researchers call "over-mixing"—a pathological state where deep models processing long sequences blur important distinctions between tokens. The presence of a sink draws attention away from other tokens, limiting the spread of information (and noise) and resulting in more stable embeddings.

This sounds like it is working for the wrong reasons. Surely the right behavior is for the right neurons to receive attention rather than the first handful. Jamming everything there is the complementary sin of blurring. I would investigate attention equalization paired with a sparsity prior or something similar to prevent blurring.

I have a 2011 Subaru Forrester. It has 5 on the floor. Once when I pulled up to the post office I took it out of gear and pulled the parking brake. A fellow had pulled up right next to me just then. He asked me "Is that a manual? I thought I heard a parking brake!" I answered in the affirmative. He offered to trade me his Jeep Wagoneer straight up, no questions. I politely declined.

I've been trying to use HTML's native popover and dialog recently. The promise of not having to write/import focus traps, better integration with standard platform "cancel" UX, the top layer concept, etc made them sound great, but in reality it's been kind of painful.

Stacking order when you have multiple modal dialogs and popovers in the top layer is based on most recently revealed element, so that toast that just opened is now hidden under a dialog. Anchoring is currently only supported in Chrome, so popover tooltips show up in the corner. Firefox supports transition animations when opening a dialog but not closing it. The web platform feature needed to tie the mobile back button to closing a dialog isn't actually implemented yet. Frameworks that patch the DOM might clobber modal dialog state because it's a function of both the "open" attribute and the result of showModal().

Some of these will improve but I think the display order problem is here for the long haul.

The new trains can go to 160mph, which is slightly faster than the old ones. But...Acela's speed is really limited by the safety of the tracks not the train sets. I remember when they were testing 155mph service in 2010, but they could only do it on tiny sections of the track. Sadly it only really gets faster once they fix the infrastructure like bridges.

> There's no reason that an LLM couldn't (or isn't) being trained on commit messages.

You are arguing that it could. Hypotheticals.

But getting back to reality, today no coding assistant supports building system prompts from commit history. This means it doesn't. This is a statement of fact, not an hypothetical.

If you post context in commit messages, it is not used. If you dump a markdown file in the repo, it is used automaticaly.

What part are you having a hard time understanding?

Sorry, but EU workers commonly have unions.

Edit: To extend a little bit, just saying that unions aren't the main problem with not having better public infrastructures in the US. Also, unions models are different outside of the US. I don't have a lot of information about US unions, but I've felt like the model is a lot more individualistic and closed to the sector they're working for, and in Europe go hand in hand with global workers unions.

If your mortgaged house depreciates while you are still paying off the mortgage, you still need to pay the original, un-depreciated amount. You'll also probably need to pay interest accumulated during the time the property was mortgaged, which means you can't use it to avoid inflation.

What lender do you know of who will voluntarily reduce your mortgage obligation if the property depreciates?

Roughly: Meteor required too much vertical integration on each part of the stack to survive the strongly changing landscape at the time. On top of that, a lot of the teams focus shifted to Apollo (which at least from a commercial point of view seems to have been a good decision).

Ah great, not so bad then! So you just need to:

- Form a German holding company to manage the business

- Deal with any conflicting taxation/regulatory issues when operating a german holding company from your new country of residence (in some countries this is not trivial)

- Visit Germany twice per year and potentially more to deal with German authorities that require things be done on paper and in person (hope you didn't move too far away and hopefully you don't have small children!)

- Hire an abnormally expensive tax advisor, hope he is good

- Sell a large portion of the company to fund a giant exit tax bill (!!!!). For many companies this is likely a 1-2 year minimum process, and that's IF they can find a buyer. Not as many PE funds in Europe. Good luck on valuation when the buyer knows you're in this situation.

- Hope the government gives you a reasonable valuation on your company, and hope their decision is similar to that of your buyer (and the timelines for both line up), which I'm sure is a super easy and not at all complicated process.

Fun! I can't possibly see what people are complaining about.

One of the weirdest things about Europe is the irrational nationalism that arises when you tie a language, ethnic-identity, government and country into one thing. Anecdotal, but it feels like this leads to more of an inability to reflect on and criticize things. Americans have far thicker skin when it comes to criticizing themselves.

Can you not see how this incentivizes entrepreneurs to leave or start their companies outside Germany (not sure if you're aware the EU exists). Is this really how you think things should work in a non-authoritarian regime with democratic freedom of movement?

> Is there any scenario under which tariffs wouldn’t raise consumer prices?

Yes, but price levels aren't inflation; inflation is defined as the rate of change. That is a component of why it is a bad measure - the long term inflation impact is effectively nothing because it is one off shock then the inflation from tariffs will disappear. The problem is the amount of stuff people can afford will drop and probably stay down which isn't well captured by inflation.

In some hypothetical world, the Trump admin could adopt a 0-inflation policy, stop printing money and still cause inflation to disappear completely over their term. It'd be a massive shock to the system, but inflation in the modern era is always a policy choice and will be unrelated to tariffs. The natural state of a market is deflation.

It seems like it'd be quite difficult for the Trump tariffs to be inflationary under the generally accepted standards of the last few decades. "Inflationary" in politics generally means that the rate of change changes over a long period of time. Krugman does this himself at the end of the article where he focuses on the inflation rates through half the Biden presidency - he's not considering how the price levels changed but the 3rd derivative of prices over half a term! If you do that to Trump then the effect of the tariffs will probably disappear too.

Trump's policies are clearly intended to push manufacturing back to the US and I think pretty much everyone would have to agree that is going to cost US citizens a lot of money. The reason they outsourced all their industrial might to China in the first place was because it was cheaper. It is a fair point, but it is annoying to see an economist trip over their own definitions like that. It is already a definition that isn't really suitable for politics. The focus here needs to be on real income.

Shell commands and files on disk are the classic narrow waist, and this type of tool, exemplified by Claude Code, locates a coding agent down in that ecosystem.

Why shouldn't you be able to use the abilities of this tool as a batch command, connected with all your other basic tools, in addition to interactive sessions?

Cursor's chat being locked in an IDE sidebar has felt like driving with a trailer attached. For some tasks the editor is secondary or unnecessary, and as a papered-over VS Code fork, Cursor has a lot of warts that you just had to accept. Now you can just use your favorite editor.

Companies make apps but want to be platforms, so they try to put everything in one app and help you forget about everything else. VS Code and Figma, for example, make their own extension ecosystems rather than connecting outward, because it makes them platforms-as-apps and harder to leave. But a desktop task workflow spans many apps and windows. You compose it yourself to your needs. We are computer users more than app users.

To me as a computer user, a tool that's compact and has compatible outward extension points feels good.

> That hardware cost Apple tens of billions to develop

Despite which, they sell them as consumer devices.

> and what you're talking about in term of "just the hardware needed" is so far beyond consumer hardware it's funny.

Not as big a gap as you might expect. M4 chip (as used in iPads) has "28 billion transistors built using a second-generation 3-nanometer technology" - https://www.apple.com/newsroom/2024/05/apple-introduces-m4-c...

Apple don't sell M4 chips separately, but the general best-guess I've seen seems to be they're in the $120 range as a cost to Apple. Certainly it can't exceed the list price of the cheapest Mac mini with one (US$599).

As bleeding-edge tech, those are expensive transistors, but still 10 of them would have enough transistors for 256 GB of RAM plus all the compute each chip already has. Actual RAM is much cheaper than that.

10x the price of the cheapest Mac Mini is $6k… but you could then save $400 by getting a Mac Studio with 256 GB RAM. The max power consumption (of that desktop computer but with double that, 512 GB RAM) is 270 W, representing an absolute upper bound: if you're doing inference you're probably using a fraction of the compute, because inference is RAM limited not compute limited.

This is also very close to the same price as this phone, which I think is a silly phone, but it's a phone and it exists and it's this price and that's all that matters: https://www.amazon.com/VERTU-IRONFLIP-Unlocked-Smartphone-Fo...

But irregardless, I'd like to emphasise that these chips aren't even trying to be good at LLMs. Not even Apple's Neural Engine is really trying to do that, NPUs (like the Neural Engine) are all focused on what AI looked like it was going to be several years back, not what current models are actually like today. (And given how fast this moves, it's not even clear to me that they were wrong or that they should be optimised for what current models look like today).

> Fairly sure most Windows laptops are still sold with 8GB RAM and basically 512MB of VRAM (probably less), practically the same thing for Android phones.

That sounds exceptionally low even for budget laptops. Only examples I can find are the sub-€300 budget range and refurbished devices.

For phones, there is currently very little market for this in phones, the limit is not because it's an inconceivable challenge. Same deal as thermal imaging cameras in this regard.

Way too little information on the homepage. Does this handle pagination? What about sites behind authentication? I assume the generated API is stable, i.e. the shape of the JSON will not change after a scraper is built, but what if the site changes it's DOM, does the scraper need to be regenerated? Does this attempt to defeat anti-bot and anti-scraper walls like Cloudflare?
