Demand that they recognize. Businesses only recognize demand in narrow bands... if they don't sell eggplant, then they can't check to see how much eggplant is moving and increase supply of it. At best, they have to rely on business intelligence that 3 years after the entire country has gone eggplant wild "hey, maybe we should be selling eggplant too". In other words, they're completely blind to demand that doesn't rise to the level of "some fad or mania for this product has emerged".

Absolutely nothing was accomplished but the undermining of the US as a stable partner. US treasuries and the US dollar both have taken a colossal hit that is going to reverberate into much greater consequences. It is the hit on TBills that forced Trump's retreat, which his weird cult now need to spin into some 4D chess.

Like, listen to what Trump himself says to justify the pause-

https://bsky.app/profile/atrupar.com/post/3lmfosw5usb2f

Basically "everyone was saying this was really stupid -- getting "yipeee" -- so I paused it". Not "Haha now I've got them where I want 'em!"

These pauses and this chaos is literally the worst of both worlds. Christ, he would have done better either cancelling them or going full bore.

Congress needs to remove his ability to levy tariffs under his imaginary emergencies.

> Now is the ripe time, 90 days, to make a deal with the US and offer the best terms.

What terms? Remember, the tariffs were not reciprocal -- that was a boldfaced lie. They were based on trade imbalance. So what, Cambodia is supposed to pledge to buy ... what exactly? ... from the US in order to balance its trade?

The reason Cambodia or Vietnam have a trade imbalance is because US/other companies have factories there to produce the goods. You think those companies are going to set up garment and shoe factories in the US? With what labor?

The whole thing reeks of a shockingly inept understanding of global trade and economics.

>We are doomed imho.

I encourage you to take action to prove to yourself that real change is possible.

What you can do in your own life to enact change is hard to say, given I know nothing about your situation. But say you are a parent, you have control over how often your children use their phones, whether they are on social media, whether they are using ChatGPT to get around doing their homework. How we raise the next generation of children will play an important role in how prepared they are to deal with the consequences of the actions we're currently making.

As a worker you can try to organize to form a union. At the very least you can join an organization like the Democratic Socialists of America. Your ability to organize is your greatest strength.

> They've stopped fluoridating their water in Scandinavia for years now.

Note that Scandinavia has naturally high fluorine levels in their groundwater:

> In Sweden, fluoride concentrations in drinking water from water treatment plants have been reported to mostly range between 0 and 1.5 mg/L, with a maximum level of 4.1 mg/L, while in private wells in South-Eastern Sweden, it was found that 24% out of about 4,800 wells exceed 1.5 mg/L. In Norway, a study from 2017 found that 4 of 201 waterworks had fluoride concentrations exceeding guideline value of 1.5 mg F/L. In a study from Western Norway, the fluoride concentration in selected wells ranged from 0.51 to 8.0 mg F/L, and drinking water was the only dietary variable associated with increased risk of dental fluorosis. In Denmark, analyses of drinking water show most sources being low and below 1.5 mg F/L.

https://pmc.ncbi.nlm.nih.gov/articles/PMC10770722/

The US targets 0.7 mg/L.

Many European countries also choose to add fluorine to milk and/or salt instead of water.

I have a trip to China on Saturday and I'm worried about:

a. Chinese retaliation. I don't think they are going to start arresting Americans, but it might get uncomfortable if I don't have my passport in the subway station.

b. American retaliation. My wife has a greencard, this is actually worrying me more than anything, although as far as I have heard so far, we should be OK.

Trip is still on. I'm really interested in how China has changed since I left 8 years ago.

> Because of the TPUs, or due to other factors?

Google does many pieces of the data center better. Google TPUs use 3D torus networking and are liquid cooled.

> What even is an AI data center?

Being newer, AI installations have more variations/innovation than traditional data centers. Google's competitors have not yet adopted all of Google's advances.

Not that I've read. They are definitely bringing on new data centers, but I don't know if they are initially designed for pure-AI workloads.

From an article written in 1979:

>He once told me: “I won’t make a deal just to make a profit. It has to have flair.” Another Manhattan developer said it differently: “Trump won’t do a deal unless there’s something extra — a kind of moral larceny — in it. He’s not satisfied with a profit. He has to take something more. Otherwise, there’s no thrill.” [0]

Except they implemented the decision and are responding to countries’ willingness to negotiate fair trade terms, just like with Mexico. Nobody is saying “just joking”. If people weren’t 1000% dismissive of the leader’s stated intentions they might be able to follow along. It’s been crystal clear to me that the goal has always been to renegotiate trade terms not to live in a world with persistent reciprocal tariffs.

Given the name I was also expecting some clever SQL-like data structure/query for fast spatial lookup but I digress.

Game physics involves a lot of things (solvers, collision detection, numerical stability, etc.). I am skeptical of their claims of being able to run physics in what I understand are stored procedures for their database.

I looked at their docs for physics https://spacetimedb.com/docs/unity/part-4 where they demonstrate the simplest form of collision check (sphere overlap). I fail to see how that is an improvement or speedup over existing methods. Some quotes: "This may not be the most efficient way to do collision checking (building a quad tree or doing spatial hashing might be better), but SpacetimeDB is very fast so for this number of entities it'll be a breeze for SpacetimeDB." >> Nothing is quantified with numbers.

"For every circle, we look at all other entities." >> This is the most inefficient N^2 way you could do collision detection.

And not to mention networked physics is a whole additional layer of complexity, where you have to use some form of prediction techniques and very likely end up changing your core physics code to accommodate this.

All of this suggests to me much thought has not been put into the claim "you can also do physics with it!" and its implications. Perhaps it is enough for extremely simple physics, as demonstrated with their demo game. If the author is reading this, I suggest spending some time understanding what this claim implies and qualifying it better.

However I must mention that I applaud their courage to try something so outlandish. If you truly believe your claims are possible, I encourage you to keep working on it.

But I'll be convinced when extraordinary evidence backs extraordinary claims.

"DOJ will no longer prosecute cryptocurrency fraud" is clickbait and not what the Todd Blanche memo says.

They will still go after the Sam Bankman-Frieds:

>Prosecutors shall prioritize cases that hold accountable individuals who (a) cause financial harm to digital asset investors and consumers; and/or (b) use digital assets in furtherance of other criminal conduct...

But seem to be intending to deal with whether it is ok to do things like issue trump token by setting regulations rather than prosecuting companies after the event. Which is not wholly a bad idea.

Show HN: Repo Roast – a real-time feed of the funniest comments on GitHub
by OG_BME | 2025-04-09 19:10:54+00:00
Hey HN - I'm Mason, and I'm excited to share a fun side project I've been working on recently: Repo Roast.

For me, Github often feels like a serious (and sometimes soulless) place. I built this website to showcase the human, silly side of developers. Repo Roast is built on top of LLM-powered GitHub analytics tooling we’re developing internally at Merit Systems [0].

One of the historically cited weak points for LLMs has been their sense of humor. I found that with the right prompt, at scale, they mostly can _identify_ humor pretty well. We experimented with a couple of different models to tune the cost/effectiveness and eventually landed on a strategy where we have gpt-4o-mini do a very light filter pass to reduce the number of calls to GPT-4o to do the actual humor scoring. Interestingly, our first prompt attempts ended up surfacing wayyy more aggressively NSFW content, which is funny that this happens despite all the censoring that OpenAI is doing.

So far we have processed the last 90 days of historical comments and continuously process new ones every hour. We theoretically can run this against a wider historical window given there is sufficient interest to justify the costs!

Repo Roast is in no way intended to make you a better or more productive dev. You can use it as a leaderboard or hiring tool (if you’re looking for personality), or just a way to distract yourself!

If you've had any funny Github interactions, I'd love if you shared them below.

Cheers!

--Mason

I wonder if there is a way to measure the effects of attitude and if it plays a role. For example, my in-laws are both diabetic, one is insulin dependent, and both my spouse and I are astonished at the lack seriousness that they both have towards their health. As in, not measuring their blood sugar levels on a regular basis, and then just taking a shot of insulin at whatever-dose, because they didn't measure their blood sugar level. Missing doses, not making dietary adjustments (excessive sugar/candy intake), etc.. Not sure if it is solely laziness, or some sort of low-level brain damage, or asense of entitlement that the world will just cater to me, or giving up on life, or what.

Nice thanks.

I'm no one and no one cares about what I say, but social media is a nice play to write about my own thoughts.

I wonder if in the future people will learn about thinkers' thoughts from their media postings, and cite their communications on papers and wikipedia, similar to how old letters are considered primary sources for great thinkers thoughts.

> do a real full backup without some encrypted databases that only facebook, google or apple hold the key for

Game developers pushed really really hard for this, to combat cheaters or those wishing to skip on in-app purchases and ads.

And Netflix was the driver behind the anti-rooting measures, who in turn were pressured by the MAFIAA and other "rightsholders" (aka, parasites).

If USA keeps 10% tariffs for everyone equally, why should we interfere? Serious question.

I believe that Trump is shaking things off, but his goal is to introduce a fixed "tariff" like a soft VAT.

He is just testing (and profiting with $$$$$) what happens when you do things like 30% there, 24% there, etc. But his long term goal is a fixed tax. In that context, who are we to judge them? We also have VAT on imports.

Yeah, misspoke, I meant selling the option, not exercising.

> Also, the current VIX is the same as January of 2020. If you believe the current state of the world is less certain than the outbreak of a global pandemic, I have some options to sell you.

I don't know if it's more volatile, BUT it it has shot way up since yesterday, and it doesn't seem too weird to think that it will go down to the numbers we had yesterday.

> If you could build the house using only resources that you already have than you would have 100k dollars AND a house.

You still have to spend money on materials and labor - they are never free. You need to take them from other uses, and people may outbid you for them. There isn't infinite lumber and labor lying around the US for free - building houses is expensive!

The core of economics is there is a scarcity of resources and we want to allocate them as efficiently as possible. Money's fungibility allows us to move resources easily and rapidly. I can send you $50,000 much more easily than my car - you might be on a different continent; you might not even want my car or agree on its value, but I can count on you wanting $50K because you can buy whatever you need with it (a car, a few servers, a trip around the world ...).

It turns out in reality that someone with better skills and capital (hard resources, such as heavy equipment) can build a house so much more efficiently than you, that you would save money by hiring them rather than doing it yourself. That's specialization, another economic fundamental. Think of most work - orthopedists, C developers, pipe fitters, etc. They are so much more efficient than you are, you wouldn't dream of trying to do it yourself (on any significant level) - even if you are in the same domain, such as internists or Python developers.

You don't lose out at all, because they also hire you to do what you are specialized at. Then instead of the farmer building a house and the carpenter growing squash, both get better and more houses and squash for much less money.

> If you can take resources from some part of the world that you don't really care about, then you are adding wealth to your own country for basically free.

If you shoot someone on the street, you can take their wallet for 'free'!

... You are arguing against fundemental economics and even basic accounting. If you care about these things, learn about them a little. Microeconomics is actually fascinating, and basic double-entry accounting is essential.

From the outside, it looks like he's doing whatever he wants without control.

He starts to tell that everyone is maintained by the US - lol what?

He starts blaming Europe for being a parasite (thanks!) and treating Zelensky like everyone has seen live.

No one is telling him that his actions will have consequences for the US in their international credibility (gone) and relationships with partners (ruined)?

One day, he does a totally broken linear regression and applies no sense tariffs to every country in the world (no Russia - weird enough).

It's well known that tariffs are not a way to attract investment in your country - there's a lot of theory and historical examples that demonstrate that.

Moreover, it's just absurd to think that these kinds of actions are going to make American (!) corporations, now producing elsewhere, back in the US. No supply chain ready, lack of resources, ...

I don't know - it looks like a single man has too much power and no one around him is helping him make better decisions (for the country) in the long term. On the contrary, it looks like all the decisions are pretty much market manipulations in order to make some "friend" get some money.

But again, this is what it looks like from the outside - and it's quite worrying
by nilkn | 2025-04-09 19:12:47+00:00
I believe the point is power, and from that lens everything makes perfect sense. Trump is exercising available levers of global influence -- for good or for bad -- in a way that hasn't occurred since Hitler initiated World War II.

Tariffs are appealing to him because they are incredibly forceful blunt instruments over which he alone has almost complete control. They give him immense, immediate influence over the entire world. What we're seeing is that the US President today, if the full capacities of that office are pushed as far as possible without violence, is arguably one of (if not the) most powerful human beings ever.

Beyond this, Trump has said that one of his greatest weapons is uncertainty. He wants to be feared. Having people genuinely afraid of you is the next step of power that he is already flirting with by posting videos of people being blown up in warfare on social media.

How can his supporters appreciate all this - constant - chaos?

"Burn it all down" is popular on both the far right and far left.

it looks like the US president can literally do whatever he wants without being subject to regulations or facing any consequences

Yes, presidents have been given far too much power to do whatever they want by declaring a fake "emergency". It's inexcusable that Congress hasn't put a stop to this.

Their reasoning is called "extending thinking". It was released alongside Claude Sonnet 3.7.

They have web search, but it's true, no "deep research". It honestly is not very good and it's WAY too trigger-happy with it. As a result, if you accidentally leave it on, you get terrible answers to simple questions that non-search mode would have answered well.

(And for context Claude Sonnet 3.7 is my model of choice)

This article feels a bit clickbaity. The sub-headline from the Washington Post article linked from The Verge article reads...

"The department [DOJ] won't pursue cases it feels are better left to financial regulators, focusing instead on crimes committed with cryptocurrency."

Correct me if I'm wrong, but this doesn't feel all that out of the ordinary. The SEC normally prosecutes exchanges. The previous US administration (Biden) created a special team in the DOJ to target cryptocurrency exchanges in the wake of FTX. The new administration (Trump) disbanded the team to refocus DOJ on other priorities, primarily terrorism, including crimes committed with cryptocurrency. SEC and other agencies will still police exchanges. It feels a bit of a leap to say fraud is now legal. Probably not a leap to say Trump is pro crypto since he seems obsessed with overall market stats.

The SEC needs to clarify it's rules around crypto. AFAIK, it's been a mess for years with a lot of uncertainty around how to operate.

Here's a random article from CNBC that explains it in more detail: https://www.cnbc.com/2025/04/08/doj-ends-crypto-enforcement-...

I suppose I can expect this comment to get downvoted. But if we keep overreacting to everything Trump does, we'll likely miss the bigger abuses of power. It would be nice to be able to discuss biz policies once again without the flame wars. The recent policy shift from being hostile to crypto to being more collaborative seems a good thing. And yes, we need to keep a close eye on where this goes because people will try to exploit it with fraud.

That's the true aim behind all of this constant course shifting. The ultra rich, those who have large amounts of liquid assets or outright cash, can make bank at the moment... buy the dip. Even if the markets dip another 20%, they'll rebound soon enough.

At least we got the Gulf of America. The only question now is, now that we've alienated our allies, shown our unwillingness to cooperate on anything, demonstrated our inability to back up our show of strength, openly laid out our lack of solidarity, and established our irrationality and volatility to the world, how long will it take China to decide to waltz a few battleships into Hawaii and claim the Pacific as the Gulf of China.

Yeah, 1v1 TGM didn't leave a good first impression on me because the items seemed wild and gimmicky, something designed for casual play, not competitive. But I eventually came around, mostly after finding out how the garbage system works. I've played quite of bit of TGM2 on Fightcade, and while some individual games come down to item craziness, usually people play FT3 or FT5 matches, where the luck of a single game usually doesn't decide the match (and if it did, it was a close match otherwise). I like the tension and surprises that items can add, even if it comes at the cost of balance sometimes.

I played a decent amount of Puyo Puyo back in the day (mostly Tsu), but lost interest for two reasons:

1.) I had nobody to play against, and the AI in the old games wasn't very good. Neither of these are issues now though, with online play and much better AI.

2.) I could never get past the beginner phase. Making 4-5 chains really fast was usually good enough to beat the AI in the old versions, so I stagnated there. But that doesn't work against modern AI, and certainly not against humans. But I had no idea how to make the jump from beginner to intermediate; strategy just felt fundamentally different, and hard for me to figure out. Maybe I just never found good resources for learning that (this was 20+ years ago, probably much more out there now).

But yeah, it's a shame it never really took off in the west. Highly underrated game.

I'm building something similar. One area I see being a massive problem is separating 'brands' and 'products', especially with companies that do a really poor job of delineating between their different brands over time.

For example 'Quickbooks', 'Quickbooks Online', 'Intuit Quickbooks' all show up occasionally when you ask about 'Accounting software'.

As an aside 'Accounting Software', I'm not seeing QBO in the top 3, and Freshbooks in number one. I have never had that result whenever I've run reports.
