The real story is the US ceding economic leadership in emerging markets like green energy, and instead encouraging its energy and automobile companies to pursue strategies not actually aligned with long term growth.

Even in the US the vast majority of new power generation is clean energy. EVs and Hybrids are about 20% of new car sales and climbing. Even if there’s a short term road bump with oBBB, battery innovation and costs continue to drive cost down.

The US economy will suffer by not trying to compete in these markets, and will need to depend on other economies more and more.

We really should have understood what was going to happen in the world when someone else tweeted:

"Based on current trends, probably close to zero new cases in US too by end of April"

Many things make me think Elon Musk uniquely benefits from Gell-Mann amnesia but the idea that anyone should have listened to him about anything other than rockets or cars should have been jettisoned right then and there. Because what he was saying was unsupportable by evidence right at the moment he said it.

Instead, here we are.

As an immigrant to Germany, I've often made the observation that Germany frequently has a really severe implementation problem. So I'm generally very sympathetic to that idea.

That being said, I'm not entirely sure that's the case here, and this is often also brought up in the context of strengthening the inheritance tax in Germany. In both the inheritance tax and the exit tax, the inherent applicability conditions are such that the end result is that there simply aren't that many people in a situation where it actually has a measurable impact. For the exit tax, you'd need to find people who 1. want to leave Germany, 2. already started a company here, 3. that company grew large enough that the Wegzugssteuer would really be a burden, and 4. that don't have enough liquidity, or cannot raise enough liquidity by selling some of their ownership, to cover the tax. That ends up being a really small number of people, which always eases questions about the reasonability (Angemessenheit) of the law. And in the context of inheritance tax, there's the added point that there's a floor to its application.

As another commenter mentioned, even for those situations where the exit tax actually is burdensome, just as with inheritance tax, there are two really simple solutions: first, create a floor for the minimum valuation by which the exit tax is actually assessed, and second, allow you to "sell" shares to the German government as a means of paying the tax, turning the Finanzamt into a silent shareholder in the company. I think both of these would be substantial improvements to both the German exit tax and inheritance tax.

My phone still has gpt-4o which gets it right: https://files.catbox.moe/0yg6cu.jpg

But my browser has gpt-5 which says 3: https://files.catbox.moe/63qkce.jpg

Claude spells it out letter by letter: https://files.catbox.moe/f1irfx.jpg

So I thought GPT-5 Thinking might get it right, and it does: https://files.catbox.moe/xlchnr.jpg

It refuses to show the thinking process for this question though, so its unclear if it even used the reasoning model or fell back on a non reasoning one.

> While GPT‑5 in ChatGPT is a system of reasoning, non-reasoning, and router models, GPT‑5 in the API platform is the reasoning model that powers maximum performance in ChatGPT. Notably, GPT‑5 with minimal reasoning is a different model than the non-reasoning model in ChatGPT, and is better tuned for developers. The non-reasoning model used in ChatGPT is available as gpt-5-chat-latest.

Really? Is that why Project Warp Speed was both an achievement for Trump and at the same time vaccines were produced too fast and hence unreliable? That is at the same institutions were a friend, when it fit the narrative and enemy, when it didn't fit the narrative. People who say - "Don't trust the government, they make terrible decisions" are now saying "Trust the government". What a turn around.

Hopefully people who have voted for this and defending this remember this as the beginning of the end of American exceptionalism. It's certainly not happening any time soon. Maybe decades later but these things will be remembered in the same way as Mccarthyism.

I doubt Gemini has a fake prompt as such. On AI Studio with web search disabled Gemini 2.5 pro insists it is connected to a real time search engine and will insist it is the year 2024 and is consulting with live search results when it delivers 2024 news as breaking news.

I think Gemini hallucinate a lot about how it is functioning.

Interestingly I'm currently doing a version of that except with top-bottom and bottom-up approach.

I.e. like you describe I the younger sales rep on the team am going bottom-up after the smallest guys. And my boss, the CEO is going after the top management. We're both selling the same thing but with different argumentation.

The idea is that the buzz of excitement will turn into consensus when everyone in the middle sees approval from the top and positive feedback from the bottom.

That is a good point -- though perhaps a better solution there would be to simply make the use of an asset as collateral into a taxable event, and treat money borrowed against it in excess of the original value as capital gains.

I know this is a very common technique that people use to effectively liquidate assets without incurring taxes, but I think it can (and should be!) solved without penalizing people who simply hold an asset.

> Save a vibe today and send an IM instead of an email thread.

I would rather the email honestly. IMs usually have the expectation that I'm going to respond to you "soon", which is an interruption/distraction. And they don't contain enough information so I have to start going back and forth with the other person.

At least with email, most people recognize that you will respond in your own timing in the next 24-48 hours. With IM I've found that expectation out the window.

Save the distraction. Send an email.

You're getting downvoted, but you have pointed to a possibly important factor. We're intelligent, but definitely have primate intelligence, and we're closest to the murderous bastards known as chimpanzees.

That said, nothing about this has been inevitable. So many accidents along the way. There are many other results that have been possible. Our social/political setting may be related with technology but it's wholly unclear how deterministic each step has been.

It is trivial:

1. Initiate pairing via the entertainment system interface.

2. Use rolling codes. Don't allow rewinding the codes.

3. Add a tiny tiny bit of non-volatile memory in the keys so that batteries can be changed without breaking the key. This is only necessary if the car can't be entered using the physical key, otherwise the user can just open the car with the physical key, turn on the ignition and re-pair the key.

I could make a secure system to do this and I'm no crypto genius. (Note this would still be vulnerable to rolljam but that's not a very practical attack, and defeating that is a bit difficult.)

To support car hire/share places if they want to prevent users pairing new keys you could allow setting a password on the pairing interface.

No, a mortgage is a loan. You don't "make" any money by taking a loan since you obviously have to pay the money back.

Don't worry that if a loan was considered "making money" it would be taxed as income... which would make no sense at all. In fact, disguising transactions as loans while not intending to repay the money is a well-known tax evasion scheme, which tax authorities always keep an eye on.

Personally I prefer to be sent a full email thread over a message in chat, because

a) I can ignore it until I have time to look at it

b) You can see who else has already been involved in the conversation - seeing a fellow team member being involved can help avoid falling for situations where someone is trying to work around one of your colleagues who's already told them they can't have what they're asking for.

c) The chat message is from an individual, so you only get their interpretation of what's happening - if there's an email thread then there's going to be multiple people involved, each with their own perspective.

Off topic, but where should one start learning writing physical simulation?

Several years ago I ran into this project [0] and got overwhelmed even the algorithm can be written in 88 lines of C++. I realized that out of all CS topics, physical simulation is probably the one I knew the less (not saying I'm a compiler/database expert or something, but at least I've implemented a toy compiler and some basic data structures used in database. When it comes to physical simulation my bran just draws a blank.)

If you get used to Jira, especially Ubisofts internally hosted Jira (which was in an oversubscribed 10yo server that was constantly thrashing and hosted half a world away) ... well, it's easy for things to feel "impossibly fast".

In fact in the Better Software Conference this year there were people discussing the fact that if you care about performance people think your software didn't actually do the work: because they're not used to useful things being snappy.

Web applications have become too big and heavy. Corps want to control everything. A simple example would be a simple note taking app which apparently also has to sync throughout devices. They are going to store every note you take on their servers, who knows if they really delete your deleted notes. They'll also track how often you visited your notes for whatever reasons. Wouldn't surprise me if the app also required geolocation and stuff like that for whatever reason. Mix that with lots of users and you will have loading times unheard of with small scale apps. Web apps should scale down but like with everything we need more more more bigger better faster.

The article does mention they only turn on “TreatWarningAsErrors” in production builds.

It’s definitely a tough balance to strike. I go back and forth on this myself.

Maybe the happy medium is to have everything strictly enforced in CI, relatively relaxed settings during normal dev loop builds and then perhaps a pre-commit build configuration that forces/reminds you to do one production build before pushing… (which if you miss, just means you may end up with a failed CI build to fix…)

Parent says it's an outlandish claim that they can reliably tell whether ads are clickbait.

I believe that detecting whether an ad is clickbait is a similar problem -- not exactly the same, but it suffers from the same issues:

- it's not well defined at all.

- any heuristic is constantly gamed by bad actors

- it requires a deeper, contextual analysis of the content that is served

- content analysis requires a notion of what is reputable or reasonable

If I take an LLM's definition of "clickbait", I get "sensationalized, misleading, or exaggerated headlines"; so scams would be a subset of it (it is misleading content that you need to click through). They do not provide their definition though.

So you have Google products (both the Products search and the general search) that recommend scams with an incredible rate, where the stakes are much higher. Is it reasonable that they're able to solve the general problem? How can anyone verify such a claim, or trust it?

Anybody knows of a simple non-destructive anti-theft mode like a fuse-switch one can easily install himself on basically any modern car? I need something I can remove and the manufacturer/dealership cannot then see I used it (otherwise they may try to whine about me having broken the car manufacturer warranty).

One of my older (collectible) car has various anti-theft helpers, including trackers. I also remove its steering wheel (easy, no airbag). Then I disconnect the battery. But then my favorite on that car is a kill-switch I had installed on the fuel pump: it's hidden and you flip the switch, car stops instantly. That one if thieves want to steal it they either have to come with a steering wheel, find the trackers, find the switch, hook up the battery or come with a tow truck (they'd still need to get rid of the trackers though).

But yup I'd like to know if there's a simple fuse-switch DIY that's non destructive: basically something I can remove and put back the regular fuse and the car dealership would be none the wiser that I used one.

Anyone know of such a thing?

It also depends on how the company is valued: If based on balance sheet (retained profits + share capital) e.g. 5×100k retained = 500k value, the exit tax is 18k/year for 7 years. If simplified earnings method with factor 13.75 is used it much higher valuation, the exit tax is at the 42k/year.

This is part of the trend of "there needs to be room for opposing views". Similar to when JD Vance visited Europe in February and scolded the EU on not suppressing views from elements such as AfD, which is essentially East Germany in every demographic.

When asked about the Indian Removal Act, President Andrew Jackson stated that if he had not taken the action, the native peoples would have been wiped out. Effectively he was saving them from genocide.

"According to historian H. W. Brands, Jackson sincerely believed that his population transfer was a "wise and humane policy" that would save the Native Americans from "utter annihilation". Jackson portrayed the removal as a paternalistic act of mercy."

Show HN: I built a task manager that track progress, not just completion
by zesfy | 2025-08-08 12:01:18+00:00
Hello HN! Happy to share a passion project that I’ve been working on for the past 5 years, Zesfy. I built it to help me organize my weekly tasks where I can review the list every and add tasks that I want to work for today with one tap.

Other interesting feature is you can set progress to your task or automatically calculated based on the completed subtasks. It lets me show completion progress such as today task completed progress in more granular way instead of just calculate how many tasks completed.

There are so many features planned in the future such as smart input, daily routine and widget. Hope you find the app helpful. Let me know what you think.

Probably. But it is important to understand that this will matter to fewer and fewer people over time.

Because they don't edit the data to make a new objective truth that survives scrutiny, they edit the data to demonstrate their power over data.

People referring to the archived data will simply be denied access to the conversation moving forward; "our opponents keep fighting old battles when the world has moved on".

It works. And it will continue to work shockingly well even when the underlying phenomenon asserts itself in ways that are predicted by the archive data. Look at how Florida is torn between climate change denial and the actual reality of sea-level rises affecting the Keys.

Issues like this are why I don't use ai agents for code. I don't want to sift through the bullshit confidently spewed out by the model.

It doesn't understand anything. It can't possibly "understand my codebase". It can only predict tokens, and it can only be useful if the pattern has been seen before. Even then, it will product buggy replicas, which I've pointed out during demos. I disabled the ai helpers in my IDEs because the slop the produce is not high quality code, often wrong, often misses what I wanted to achieve, often subtly buggy. I don't have the patience to deal with that, and I don't want to waste the time on it.

Time is another aspect of this conversation, with people claiming time wins, but the data not backing it up, possibly due to a number of factors intrinsic to our squishy evolved brains. If you're interested, go find gurwinder's article on social media and time - I think the same forces are at work in the ai-faithful.

I have whys not whats. Why we waited so much(years!) for such api as a browser built in? Why I feel it overwhelming/not well thought off for such simple use case? I still feel like including a 3rd party library and instantiating a tooltip to be more straight forward, if anything these libraries are built upon years of know how and we don't need to wait for a browser vendor to add a new attribute on his own for a marginal improvement. Marginal improvement one would understand immediately right? No "hint" is a not a simple tooltip. And why the heck we would ever need a table grid to explain a feature that should be simple? I'm so sick of the web platform and its inefficiencies

Rigid body simulations are much much simpler. There’s a siggraph course from 2001 [0] which is a bit of a dense read but it will bring you all the way up to a full blown rigid body simulation and understanding the math behind it too.

A email thread, to me, is much preferable to any IM, unless participants knows to send those IMs in a thread as well.

All the context are in there in the rawest of forms, you a run through them with your eyeballs or have your tools do the summarisation there and then. Most of the IMs I received didn't even quote the original message they were responding to, and I end up spending time jumping up and down the channel or group to get the whole context. Not to mention folks sending me link to a slack, which, depending on the mood of the almighty slack god, can or cannot be opened in the app / current slack session.

But you do you. :)
Ask HN: Help for Choosing an Embedding Model?
by t4 | 2025-08-08 12:04:24+00:00
I've tried looking and the MTEB leaderboard and tested a few, but I'm curious about your experiences!

I'm looking for a model that would optimize for accuracy (finding relevant results), language support (as many as possible, English only is a no-no) and efficiency so I could potentially run it locally or that there's a cheap API for it.

OpenAI embedding API gets expensive real quick when generating embeddings for 10^5 documents and more.
Show HN: TAIsk – AI tool that breaks down yearly goals into daily to-dos
by FabianJani | 2025-08-08 12:04:58+00:00
Over the past few weeks I built a small SaaS tool to help myself stay on track with my goals — it turned into tAIsk.

The idea: Many people set big goals but lose track in day-to-day life. tAIsk automatically breaks long-term goals into prioritized daily to-dos, tracks progress, and adjusts the list dynamically.

Tech stack: – Backend & Auth: Supabase – AI: OpenAI API – Frontend: Lovable (low-code)

Live demo / Website: taisk.app

I’d love feedback on: – UI/UX: What’s unclear? – Onboarding: Does it need more guidance? – Features: What would you build next?

PS: The vision is for tAIsk to feel like a productive “mini-coach” over time.

Very nice, but probably a bit too expensive to just hand out.

I knew a chap that had a similar hardware business card (I don't remember exactly what it did, but it wasn't as cool as this one).

I remember that his card was pretty scuffed up, and he insisted I give it back, after he handed it to me. Bit weird.

The original comment was about whether these things should be treated as errors during the local development process, or during CI for greenfield projects.

I deleted it after realizing that the article actually does address this. But I'm still relieved that I'm not the only one with the dillema.

> which if you miss, just means you may end up with a failed CI build to fix…

Honestly as a developer if I miss this up until CI, that's on me. The important part is that these issues are still visible during the local development, even if as warnings, and that the developer knows (maybe after making that mistake once or twice :-)) that they can't just be ignored because they will fail down the road.

Counting letters in words and identifying when words are misspelled are two different tasks - it can be good at one and bad at the other.

Interestingly, spell checking is something models have been surprisingly bad at in the past - I remember being shocked at how bad Claude 3 was at spotting typos.

This has changed with Claude 4 and o3 from what I've seen - another example of incremental model improvements swinging over a line in terms of things they can now be useful for.

This multiplier would be ridiculous for an LLC you are just shareholder of but in case of one person company which usually derives most of its value from the work of the founder it's just on another level.

One person shops would rarely get 3-5x multiplier if the founder leaves. It's straight up "you belong to us" type of regulation. Next they will make you fight in the arena to win your freedom.

>>> "It's the White House that wanted Trump to be candidate. They played Republican primary voters"

The original comment did seem to imply that the 'White House' was in control, with a plan, and 'played' the Republicans.

The original comment made the connection that Democrats were taking action. If I'm allowed to assume that when someone makes a comment, that sentences are related. That sentences can follow one another and be related in a context.

And as far as my context viewing the comment. I have heard this idea ::

Trump is doing bad things -> Democrats failed to beat Trump -> Thus Democrats are the cause of bad things.

The original comment seemed to be in that vein. To attribute much greater responsibility to the Democrats for our current situation, instead of the people actually doing the bad things. aka Republicans. They are actually doing the bad things.

So much this.

Putting these walls up also makes life harder for actual customers, who now have to prove they are such every time they need to access said docs for whatever reason.

As an individual engineer, if I have to jump through hoops just to login and view docs... yeah. I won't be going out of my way to make sure you get considered in trade studies at my next job.
