If you’re curious about how the DIY open-source hardware market for Chinese-made goods is reacting to the recent 145% tariffs, check out the eBay sales data here: eBay Sold Listings:https://www.ebay.com/sh/research?marketplace=EBAY-US&tabName...

Spoiler alert: There hasn’t been any noticeable reaction yet. You might expect to see price increases or higher order volumes when searching for items like the ESP32, but that hasn’t been the case so far.

I’d love to hear your thoughts on the potential impact of removing the de minimis threshold on shipments. It’s hard to imagine how the postal system could efficiently handle tariffs on a dozen small $1 packages from AliExpress landing in the mailbox. I suspect we’re moving beyond that point, with private companies likely clearing these shipments in bulk before they reach USPS—if they even make it that far.

I watched the UK/US press conference this morning. Lutnick is infuriating. Anything remotely resembling an explanation or justification for 'tariffs' devolves in to obsequeous praise of how great Trump is. It's as if they can't function for an hour or two without overtly proclaiming the wonder of Trump.

"Jamison and I working together couldn't have put this deal together in 3 years, but President Trump was able to pull this off in less than 45 days!" (paraphrasing but IIRC it was pretty close).

Okay some further searching indicates the license that is expiring is Microsoft's export license to export Windows to Huawei. After the previous round of sanctions on Huawei, Microsoft had applied for and received a license to continue selling Windows copies to Huawei for it to resell. That is expiring, and is not expected to be renewed.

So its really an export license from the US government that is expiring.

>I question if you couldn't make it work in ~100% of cases if you genuinely tried to.

You could say this about almost any pattern, if you genuinely tried to make microservices work it could work in ~100% of cases, I'm sure of that.

Its this pattern of dismissing or accepting a solution with strong prejudice you don't evaluate the merits is the real problem. Thats the true behavior we need to get away from.

We as an industry may find, that modular monoliths trend toward the top as a result (I hate to speculate too much, every company is different and there are in fact other patterns of development beyond the two mentioned) but that would be a side effect if true. The real win is moving away from such prejudiced behavior

Maybe, but I never seem to have trouble searching for even further incomprehensible part numbers on other items. Give me a DigiKey part number like "WM7610CT-ND" and google finds it first thing. Digikey is also the first result for the manufacturer part number "0533980671".

For my McMaster example, google gives 9 results, none of which are the McMaster site. That not specific enough? To be fair, I believe McMaster to be fairly protective of their catalog.

At least their part numbers are fairly recognizable - they are usually about 10 characters long, all numbers, with an "A" near the end. That's usually enough to get me to check the McMaster site first.

To be fair, Chernobyl was an older and unsafe reactor design in comparison to the newer ones we have today.

Anecdotally, I live near the Palo Verde nuclear powerplant in Arizona, we receive all of our electricity through a combination of solar (clouds are very rare here) and nuclear. These 2 factors mean energy is abundant in the state, and necessary in the summer for survival; air conditioning is a necessity due to the extreme temperatures in the summer.

The Palo Verde plant was commissioned in the 1980, and provides more power than any other reactor in the US. Since its not located near a body of water, it uses treated wastewater for cooling. It is a Pressurized water reactor design similar to the ones used on Naval vessels, a much safer design than the one used in Chernobyl, and none of which have ever experienced a meltdown or critical failure. Overall, I've never experienced any anxiety regarding the reactor not too far from where I live, it is the least of my concerns.

I believe the future will need to be a combination of renewables, to put all our eggs in one basket in foolish. Smaller and safer self contained nuclear reactors (like the ones used on Submarines) seem very promising for data centers. AI is on the rise, for better or worse, and it's power demands are constantly growing.

Closing a question on Stack Overflow doesn't delete it or hide it from public view, so the comparison doesn't make sense. Closing an old, popular question only prevents it from receiving new answers and puts a banner at the top. The point is to avoid setting bad examples for new questions. The fact that a question was well received many years ago does not guarantee that it's in agreement with current policy.

Additionally, we generally do not close old questions simply because they're "outdated", e.g. refer to deprecated libraries etc. We recognize that people are often stuck maintaining unsupported legacy systems, effectively indefinitely. We sometimes close questions because they refer to services (especially web APIs) that are no longer available. But overwhelmingly, when old popular questions get closed, it's because they're deemed to be no longer on topic for the site. Since a lot of people will see the question, we don't want them to get the wrong idea about what's topical.

And, of course, it makes perfect sense to downvote things that used to be correct but are now incorrect. Practically speaking, this doesn't happen nearly enough; upvotes have a kind of inertia, and wrong answers are often evaluated by people who don't know they're wrong.

By the way: about 89% of up/downvotes ever cast on Stack Overflow are up (https://data.stackexchange.com/stackoverflow/query/492368/to...).

I probably just haven't checked these comment threads enough yet because I'm surprised I haven't seen this posted, but even though this is a bit old now, https://youtu.be/y8OnoxKotPQ, there is a reason it resonated with so many. It's spot on with the downsides microservices can inflict.

I've certainly seen microservices be a total disaster in large (and small) organizations. I think it's especially important that larger organizations have standards around cross-cutting concerns (e.g. authorization, logging, service-to-service communication, etc.) before they just should "OK, microservices, and go!"

The AP1000 was a new design when Vogtle 3 and 4 were planned. It was certified by the NRC in 2005. NuScale had its small modular reactor design certified by the NRC just a couple of years ago:

https://www.energy.gov/ne/articles/nrc-certifies-first-us-sm...

If you mean that the NRC holds back designs that are more exotic than plain old light water reactors, maybe so, but that isn't relevant to the "looming power crisis" mentioned by bpodgursky up-thread. Light water reactors are the most affordable and fastest to build everywhere in the world. Pressurized heavy water reactors (like CANDU) are also mature designs. Everything else is slower and more expensive to build, with very limited operational history compared to the dominant water based reactor designs.

Not sure why people keep insisting that goods from China are “cheap,” which always seems to carry a negative connotation when in reality, “cheap” is exactly what we seem to want as consumers in wealthier western countries.

And in many cases, these products are neither cheap nor expensive, they’re simply the only option, because no one else in the world manufactures them. So, what exactly are we comparing them to? And if the assumption is that producing the same goods in Europe or the US would be more expensive then that’s likely true but only because we still expect to earn a living wage, even in factory jobs

16% of American adults believe that vaccines are unsafe [1]. That's 40 million people, which is not exactly a tiny number.

While concerns about the Covid-19 vaccine are highest (24%), significant numbers of people still feel that "normal" vaccines are unsafe, like MMR (9%) and flu (11%).

Adafruit does their own assembly (pick and place / reflow) but not sure what PCB providers they have. There are US based PCB fabs.

Cyber City Circuits does small scale assembly in the US and seem like a cool company (ran into them from the Datasheet Digest podcast they put out). But yeah obviously they aren’t going to be able to match a $35 PCBA JLCPCB prototyping order.

Finally americans will experience expensive electronics. I guess nobody in US realize how much more expensive is electronics for people in EU. Every electronics is more expensive by hundreds of EUR and with added bonus, the price is same for every country in EU, which in turn means when you live in EU country where median salary is 5x lower than US, you will have great time buying electronics, steam games, etc.

I agree, and I am in favor of protectionist tariffs. But it does seem to be poor strategy to rush into high tariffs without the pieces put in the place for American industry to grow and benefit. That said, I don't believe Trump is that stupid (despite the trendy opinion to the contrary), and I think he knows this is doomed to fail if the goal is immediate American industry bloom. Which is why I don't believe these are intended to be long term. Based on how the other tariffs have gone, it seems to be more of a negotiation tactic to reduce tariffs on both sides, not protectionism. China has just put up more of a resistance to it than other nations have, so now it's turned into a game of chicken.

Even docs is understood as a plurale tantum noun like scissors, it still cannot be in a non-head position in a noun phrase.

If we make a noun phrase in which scissors is embedded as a non-head position, we take out the s.

We want to hear "scissor sharpening service", rather than "scissors sharpening service".

The latter is not considered grammatically incorrect, but it lacks euphony.

In some cases plural-sounding words can't be avoided in the middle of noun phrases, like "denotational semantics lecture". Semantics is a singular that people treat as a plural sometimes ("these semantics are ..."). We can't delete the "s" to make semantic, because then we get an adjective. That can be in the middle of the noun phrase, but it changes the semantics. A semantic lecture isn't one about semantics but one that has semantics (about any topic whatsoever).

What I'm seeing with Brokk (https://brokk.ai) is that models are not really interchangeable for code authoring. Even with frontier models like GP2.5 and Sonnet 3.7, Sonnet is significantly better about following instructions ("don't add redundant comments") while GP2.5 has more raw intelligence. So we're using litellm to create a unified API to consume but the premise of "route your requests to whatever model is responding fastest" doesn't seem that attractive.

But OpenRouter is ridiculously popular so it must be very useful for other use cases!

It is if it’s part of a strategy. The oafish nature of this expression of one man and his whack pack of losers surrounding him is beyond that.

I’m doing what most people who can are - freezing capital spend, unwinding positions and contracts that will be hit and planning for the inevitable crash in the fall. The companies that rely on advertising for revenue are going to be purging workforce — there nothing to sell.

Ironically the idiots rallying for the clown will be hardest hit when the farms loans are due and the cotton and soybeans are rotting in the fields.
Letting Go of My Beloved Project After Getting Laid Off
by Obiabo | 2025-05-08 17:01:52+00:00
A few months ago, I got laid off unexpectedly while trying to migrate a legacy codebase. Since then, I’ve been applying to jobs, diving deeper into Rust, and building side projects. But there's one project I’ve put months of love into: Potatoe Squeezy.

What started as a small birthday idea evolved into a platform for tipping open-source developers using crypto. It's designed to be borderless, crypto-native, and frictionless. On GitHub, maintainers tag issues with a bounty, and contributors get paid automatically when they close the issue. On the web app, anyone can tip anyone without needing any crypto knowledge.

The problem it solves is simple: GitHub sponsorships are slow and gated, and bounty platforms feel overengineered. Potatoe Squeezy allows devs worldwide to receive crypto tips effortlessly.

But, with the layoff, I can't keep the project alive. So, I’ve decided to sell it. The project is live and fully functional, with well-structured code, a GitHub bot, web app, and deployment guides. Despite some traction (top 1 in Web3 on Product Hunt), the project is still in its early stages.

If you're interested in taking it to the next level, I’m open to offers and will provide code, docs, and a smooth handoff. You can reach me via Twitter, email, or check the project out at https://potatoesqueezy.xyz/.

I’m also actively looking for new opportunities. Feel free to check out my portfolio and GitHub profile.

Thanks for reading — you’ve earned a virtual high five! And hey, if you want to sponsor or fund me, I’m always open, like the Burj Khalifa or the sun from afar, hard to miss!
by advisedwang | 2025-05-08 17:02:05+00:00
A company can do that on a few SKUs, but not their entire catalog. Pausing your entire revenue stream for more than a very short period means laying off staff, breaking leases, ending dividends (if you give them), taking a stock price hit (if you are public) etc. It's potentially a fatal move. Better to lose some customers than fold completely.

> but a monolith with more than 50 developers working on it (no matter how you split your teams) isn't great either.

Why can the game industry etc somehow manage this fine, but the only place where it's actually possible to adapt this kind of artificial separation over the network, it's somehow impossible not do it beyond an even lower number of devs than for a large game? Suggests confirmation bias to me.

The main problem with microservices is that it's preemptive, split whatever you want when it makes sense after-the-fact, but to intentionally split everything up before-the-fact is madness.

> because the point of the site is not to give you a personalized answer, but to build a reference where the questions are useful to everyone

This is a strawman. Marking two different questions as duplicates of each other has nothing to do with a personalized answer, and answering both would absolutely be useful to everyone because a subset of visitors will look for answers to one question, and another subset will be looking for answers to the other question.

To emphasize the difference: Personalized answers would be about having a single question and giving different answers to different audiences. This is not at all the same as having two different _questions_.

Other countries wouldn't get a permanent 125% advantage over the U.S. They have zero involvement with the tariff because it's the importer who pays it to the U.S. Treasury when the cargo arrives in the U.S. In the case where it's a single-source, IP-protected item, the tariff is largely irrelevant to the country that produces it. People will buy it if it's a necessary item. The tariff doesn't give them a reason to adjust the price up or down or do anything different at all. They sell to their U.S. wholesale customer at the same price, that wholesale customer pays the tariff, and then the wholesale customer either passes the tariff through to the retail customer or charges multiples to maintain the same profit margin percentage.

In the absence of IP protections, it would hurt the countries with the highest tariffs on their products because there would be an incentive to produce an equivalent product domestically or source it from another country whose products are taxed at a lower rate. In practice, it still doesn't work out to impose broad tariffs because no one has a fully domestic supply chain. It really only makes sense to tariff very specific items in new-ish markets where you have a foreign player whose government is subsidizing production, e.g. Chinese EV's, Chinese EV batteries, solar panels, etc.

There will be a subset of people that will avoid the harmful parts of this technology. But I see the strengths of using it. I like the parts where it helps humans improve there creative/scientific endeavors, like using the technology to run certain parts of a game engine to enhance a in-game world, but I will always prefer a human touch.

In my profession I avoid using because I really don't need it. There are part of my business where I want to focus and parts I would want to delegate to this technology. For instance, im not a coder by trade so I could see using some crash analysis AI[0] to help me debug issues.

When the MBAs of all the large corps spend decades reworking supply chains to rely on overseas suppliers, you shouldn't be surprised when you have no domestic alternatives when you suddenly pull the rug out.

None of this is by accident, of course, but it just seems predictably short-sighted, and I don't buy any of the 4d chess nonsense that some supporters are suggesting. And now the world has to bear the consequences of a misguided and overconfident policy.

I don't understand how you can equate the two and reconcile the past. The individuals who have pushed society forward in this domain or that scarcely, if ever, had any particular knowledge edge. Cases like Ramanujan [1] exemplify such to the point of absurdity.

In timeline mode, it's just a pure top 10/20/50/100 stories by points (or comments, if chosen) for each day (in your time zone). The stories are presented in chronological order in which they were submitted (top is newest).

The timeline view can get wonky when it's like 12AM-2AM when there are relatively few stories in "today".

Misc: 1) it doesn't filter out flagged stories 2) second-chance pooled items, should they rise in ranks, will be shown on the day the item was originally submitted, not the day it got popular.

I may do to a "rising" type of view but I'm curious about what others want to see first.

I feel like a broken record, but it makes perfect sense if you ask yourself, what would Putin want?

Putin would love the US government destroying large portions of its economy for no discernible gain. I think Putin probably encouraged Trump by telling him all the idiotic things he keeps repeating like how the trade deficit shows the US is getting ripped off. Or that huge tariffs will bring manufacturing back to the US. Or that countries would be lining up to make a deal.

But no actual sane person can explain the end game because anyone with even a basic understanding of economics and trade knows that none of those things are or were ever true.

> That said, anyone who wants a small phone today in Brazil needs two things: to make a generous concession to the size of what is a “small” phone and to have plenty of money, because only Apple and Samsung’s flagship phones remain in “small” sizes.

There is a third option: spend less money and buy a refurbished / second hand old phone from a time when they were small.

Phones have plateaued in the degree to which a faster chip creates a better user experience. You can live comfortably with a phone that is several years old, as long as the battery isn't. If you're the type who needs the best camera imaginable, maybe not, but I expect most people's photos are compressed enough by their social media platforms for it not to matter.

Article title doesn’t do the material justice, there’s some real gems in there.

> Now that he’s there, he says he finds himself surrounded by people who “love their jobs,” who came to the government with a sense of mission driving their work.

> “In a sense, that makes the DOGE agenda a little bit more complicated, because if half the government took [a buyout offer], then we wouldn’t have to do much more,” he says, implying software can replace departing employees. “We’d just basically use software to plug holes. But that’s not what’s happening.”

Rare earth metals aren’t very rare, they’re just messy to extract and refine.

There are reasons that the Chinese (government) want so many dollars, and the external funds are not easy to replace (or they would have done it already). This is not to support the current trade ‘war’, but just to point out that it’s a bit more complicated than you can describe in a pithy comment.

> Autopilot’s two main features are Traffic Aware Cruise Control and Autosteer. The first is self-explanatory, while Autosteer is Tesla’s name for active lane keeping.

In my EV (2025 Hyundai Kona) the lane keeping is split into two functions, described below. Does Autosteer correspond to one or both of them, or does it do more?

The two I've got are "Lane Keeping Assist" (LKA) and "Lane Finding Assist" (LFA).

LKA warns if I'm heading toward crossing the line (unless I'm signaled a lane change with my turn signal) and will provide some steering assistance to fix this.

LFA continuously adjusts the steering to keep centered in the lane.

From a nuclear energy professor at MIT in a nuclear power industry podcast, giving an overly positive but still sober image regarding the nuclear industry as it exists today.

https://www.youtube.com/watch?v=dDzaSucDg7k

In the meantime renewables and storage have gone from nascent industries to today be the vast majority of all new energy production in TWh and while costing a fraction of new built nuclear power.
