Just as a matter of logic, you can't prove wrong a rule of thumb that admits exceptions by pointing to an exception. There can always be reasons why, despite economic integration, other factors take precedence, e.g. perceived existential risks can push countries into war despite foreseen economic shocks.

In the case of Russia, while there were subtantial sanctions, it was still trading natural gas to the EU, and I believe they still are. China and India also helped Russia (and themselves) tremendously by buying huge quantities of discounted hydrocarbons, and I think it's plausible that there were indications before the war that such deals would be available.

As an aside about drones, a striking number of new companies established over the last handful of years in several European countries are military drone specialists. By now it's quite obvious why. In the future I guess there'll be a new slew of companies specializing in counter-drone tech.

I workout several times a week at a gym that has classes with programmed workouts. However, I often find myself at a hotel gym with limited equipment and no pre-programmed workout. Do I just run on the treadmill... sounds boring. So, I wrote an app/website that will takes the information below as input and output a workout. I've designed the simple interface to work best on smartphones... that's what I normally have in the gym.

Muscle group focus (up to 2 groups) Workout length (5-60 minutes) Number of movements (2-5) Fitness level (4 levels) Equipment access

It selects from a list of movement and estimated burned calories and the workout time. The movements in the workouts contains links to youtube videos of movement demos. There are calculations in the backend that:

alter the total workout time based on fitness level filters movements based on fitness level adds a bit of randomness to the rep counts for variety

I would love to have some feedback. Is this useful to anyone besides myself? Do the workout time and calorie calculations sound reasonable? What about the movement rep ranges?

Domestic production that is perceived to benefit national sovereignty is protected.

See: farming, energy, and defense spending/subsidies.

There is no point in history where any nation, anywhere, has needed to be self-sufficient in the production of Nike Air Maxes.

That being said, my sneakers, New Balance 990v6s, were made in the US-- probably Maine. They're $200.

The shoes I typically wear for work, Red Wing Iron Rangers or Work Chukkas, were made in the US-- probably Minnesota. They're $350 and $290 respectively.

I don't know if increased volume will decrease the prices by much, they're only higher than premium imports by a little bit.

There is domestic production already here.

I understand the value of perception.

A big part of my issue here is that they've really messed up the misleading benchmarks.

They've failed to compare to the most obvious alternative, which is Nvidia GPUs. They look like they've got something to hide, not like they're ahead.

They've needlessly made their own current products look bad in comparison to this one understating the long-standing advantage TPUs have given Google.

Then they've gone and produced a misleading comparison to the wrong product (who cares about El Capitan? I can't rent that!). This is a waste of credibility. If you are going to go with misleading benchmarks then at least compare to something people care about.

As far as I can tell, this is the missing feature: flags definitions are extremely semantically meaningful to humans and not even `mdoc` has expliict semantics for them (the closest you can get is that the pattern `.It Fl A` almost always means "the -A flag's definition", especially if it's in the DESCRIPTION section, but that's not a hard-and-fast rule).

And of course, even if your pager isn't `less`, by the time the content has been fed through `man` itself it's been crunched into a terminal representation, not a semantic representation. You'd have to `man -w whatever` to get the raw file and parse it yourself (and handle whether it's mdoc or man format, etc.).

The regex you have keyed that matches to "What these flag definitions usually look like on the terminal" is almost certainly the saddle-point solution between using the tooling as it is and burning it to the ground to build something better.

Ah - my attempt at doing this was almost there, except for the few bits that kept erroring out because I didn't mount the proc,dev,etc. mountpoints correctly :) Something to give another whirl on. At the time, I wanted something simple without docker to store everything development-related using different libraries. This is where debootstrap+chroot comes in - to build against various versions of libraries in Debian (if I remember correctly - it's been awhile.)

I tried playing sirtet for a while. That was pretty interesting. My brain kept wanting to orient the pieces as if I was playing Tetris leading me to occasionally do the opposite of what I was intending to do and dig myself into a hole both figuratively and literally. I found it pretty challenging to figure out a good strategy for stacking; there aren't so many lines to work with at once and the constraint that the soil has to be connected at all times adds a bit of challenge. I couldn't get very far and only managed to clear four lines a couple of times. I can definitely say now that I don't think 7 bag is a mistake for this. With the added challenge, having 7 bag and a hold window is probably a good idea.
Show HN: notperplexity – Emulating an AI-Search Engine over the Weekend
by shahahmed | 2025-04-09 14:57:47+00:00
I challenged myself to recreate the core experience of Perplexity.ai, the $9B “Google-killer", on a Sunday, using OpenAI's latest web search capabilities and a light frontend.

The result is: notperplexity.ai

Under the hood, it wraps OpenAI’s new Responses API with the web-search tool. It’s sometimes useful and mostly an excuse to see how far the primitives have come. It does beg the question of how point solutions like Perplexity can continue to grow.
Show HN: I accidentally helped coaches increase their revenue by 40%
by madjidlablack | 2025-04-09 14:57:49+00:00
Hello everyone, Madjid here.

Since I was a teenager, there have been two things I've loved most, engineering and playing the piano. Eventually, I became a software engineer. After graduating, I realized a 9-to-5 wasn’t for me. The only solution ? Building my own software. But I had no idea what to create or who to build it for.

After months of struggling ( because every good story needs some ), I saw a quote : “ If you want to build software that helps, start with a problem you’ve faced. ”

This reminded me of my university days teaching piano. Organizing lessons, scheduling, and balancing studies was a hassle, and I never found a tool to simplify it.

I researched and was surprised that even in 2025, coaches still relied on tools like Calendly and Linktree, which weren’t ideal. That’s when I decided to build a tool to help coaches save time, eliminating manual scheduling, endless messaging, and payment hassles.

I took it seriously because I knew it was a real problem. After three months of dedication, I finally launched it :

- A custom portfolio to showcase classes - Booking system for one-time & recurring classes - Accept payments from students at booking - Manage booking with user friendly interface - Overview of your key metrics - E-mail notifications for new bookings & cancellations

Now for the happy ending After launching the beta, we gained few satisfied users. Surprisingly, they all saw increased bookings, even though the tool was just a website builder and booking system.

What one of our beta users sent me : “ After setting up my website and sharing it on social media, I instantly started getting more bookings, as if people didn’t know I offered this coaching service before. ”

After researching, I realized coaches mainly shared their portfolios on social media. Many potential clients avoided booking simply because calling felt like a hassle. It sounds odd, but it's real.

Simply because it was easier to do online, they decided to book.

A server DB monolith that explicitly doesn't scale? You put some of your game logic on the server and some on the client with no clear dividing line? When PoE2 uses PostGres and Eve Online uses SQLServer? Also doesn't tackle the main challenges of online multi-player games (physics sim rollback)?

I'm sorry but there might not be a good market for this.

And what if a side is false news? There is news reported from both CNN and Fox that has been completely false.

It would not be impartial to let them lie in an effort to get to the truth. You would have to correct them, at which point someone is going to call you partial. Journalism is about actively finding the truth, but you can see in this thread, people's idea of impartiality is letting everyone talk and shrugging.

I certainly would. Getting blasted w traffic because of an insightful post is an edge case that it doesn't make sense to design around and I'm not really gonna want my personal blog to be a time or money sink when I could be spending either on things that I like more than that. So I'm gonna go with the free tier of something that provides basic protection and availability and if I do get hug-of-death'd by some content aggregator or another it's no real loss to me that they use the wayback machine rather than hit my page directly because I'm not monetizing.

> There is one other very important takeaway from disruption: companies that go up-market find it impossible to go back down, and I think this too applies to countries.

There's a lot of talking past each other here. This observation, framed a bit differently, is precisely the argument for radical disruptive change. If there's a structural ratchet mechanism, where outsourcing a particular kind of manufacturing work means the US can never do it effectively again, doesn't every tick of the ratchet pose significant risks?

I want to believe you. I just can't bring myself to agree, anymore. Most sites are flat out not optimized, at all. Worse, many of them have instrumentation buckled on to interface with several different analytics tools.

And to be clear, most sites flat out don't need to be optimized. Laying out the content of a single site's page is not something that needs a ton of effort put into it. At least, not a ton in comparison to the power of most machines, nowadays.

This is why, if I open up GMail in the inspector tab, I see upwards of 500+ requests in less than 10 seconds. All to load my inbox, which is almost certainly less than the 5 megs that has been transferred. And I'd assume GMail has to be one of the more optimized sites out there.

Now, to your point, I do think a lot of the discussion around web technologies is akin to low level assembly discussions. The markup and script layout of most sites is optimized for development of the site and the creation of the content far more than it is for display. That we have moved to "webpack" tricks to optimize rendering speaks to that.

The designers of the chips in the iPhone are basically US entities. (And more generally, Apple, Nvidia, AMD, Qualcomm, etc. are US companies.) They can gradually limit foreign production and re-shore with subsidies.

Sure, foreign chip manufacturers might gain a leg up, but it might not be totally ruinous. There's a way to do it that's smooth, gradual, and mostly painless.

I’ve always wanted to redesign my apartment, but hiring a professional interior designer felt too expensive and time-consuming.

Last month I came across this AI tool that generates interior design ideas from just a photo of your room. I was skeptical at first, but I uploaded a picture of my messy living room and asked it to design in a “Mid Century Modern” style.

30 seconds later… I was staring at a completely transformed version of my room — same layout, same space, but it looked like something out of a design magazine. I kept generating new ideas, saved a few I loved, and even used them to guide some real-world upgrades.

The AI was shockingly good at understanding light, spacing, and furniture placement. It even suggested wall art and lighting setups I hadn’t considered.

If you’re curious to try it out, it’s here: www.redesignai.co

Talking about the merits of these tariffs kind of misses the point. The person who wrote this article is very smart. I am sure they are smarter than I am. He has produced a pretty solid analysis of trade policy. But in articles like this people ascribe their own motivations and goals to the tariffs that aren't actually there. Buried in this article is the assumption that the motivation of tariffs and trade policy is to maintain competitiveness with China in manufacturing for both economic and security reasons.

This may be important to the author but it isn't a top priority for the administration. Competitiveness with China and onshoring manufacturing are certainly talking points but they is not stated as the primary motivation for the tariffs. The administration characterizes trade imbalances as countries taking advantage of us. The tariffs are targeted based on trade imbalance. If manufacturing was the goal why apply tariffs to things like raw materials? If competition with China is the goal why apply tariffs to South Korea or Japan, pushing them closer into China's orbit? These are just not the goals of the tariffs and neither their rhetoric or actions suggest that they are.

People have a hard time dealing with values and motivations that are wildly different from their own so they construct all sorts of parallel explanations and defend those instead. But talking about these explanations is non sequitur. It is like the administration adopted a policy of jailing all Capricorns and only Capricorns and people started writing think pieces about how the criminal justice system would be more efficient if they focused on programs to reduce recidivism.

Explain the strategic value like I'm 5? I see people reference this idea all the time, but I'm unconvinced it's actually valuable enough to be worth it given all the other downsides. I don't actually believe it's a positive value proposition.

I see the argument for things of military significance. The common one is electronic components. But PCBs manufacturing is easy to spinup quickly. Which leave the critical components like IC where the ones we'd actually need are still exclusively overseas. The TSMC factory being built wont produce the newest generation chips.

Same for agriculture, if we're totally self sufficient, what happens when a blight takes out a staple crop or two? You can't just spin up food production or global food trade the way you can with manufacturing.

Meanwhile, having robust global trade is just a less lethal version of MAD, here being mutually assured economic destruction. It's much harder for other nations to turn on you when you both depend on each other for comfort, convience, or survival. Look at how the US is being seen by the international community. The reputation we had as a strong ally and worthwhile partner has been badly damaged. Why would other nations want to help us now? How are we stronger alone, instead of having their eager support?

There are two people, one grows all his own food, and makes all of the tools he needs. He doesn't need anybody. The other works with his neighbors, they share food, he kinda knows how to sharpen an ax, but he uses the ones made by the guy down the street, who's basically a professional blacksmith, even though he introduces himself as a gardener.

which one of those guys appears stronger? Who's more likely to survive something bad happening? who do you think is more likely to win in a fight? (yes their neighbors will come to help) which one would you rather be?

1 company, taking up multiple positions (5-10) in multiple companies (3-5) as regular full time employees (us salary) and work is spread across lowly paid workers. and its not 8-12 people involved, that would be just 1 position. there would be about 20-50 people in these "smbs"

There's a study underway for a similar implant to help treat sleep apnea. Similar in size, multiple implants can be inserted around the nerves innervating the muscles in the throat. They would be powered by induction using a wearable collar of some sort.

Not sure why this one would be controller by light. Can anyone (heh) shed some light on that?

This MVP will solve your problem poorly but I do appreciate if you can give use honest feedback :)

Problem: Most learners forget what they've learned because they don't review or apply it.

Solution: Let users create their own practice sets and schedule reminder. See your performances in daily progress.

How: click wiyomi.com, sign in (because we need to save your quizzes), type the topic and Ai will help you generate subtopics to practice, click create, and happy practicing then.

Why: Forgetting is the default. Without consistent practice, lessons fade away.

I recently spent a couple of days tracking down a problem that one of my coworkers, who built the subsystem where the bug was lurking, probably could have figured out in an hour or two at most.

Why didn’t I hand it off? Because I need to know how this subsystem works. It’s important and quite complicated and this is not going to be the last bug we have, or the last change it needs. It’s part of what I work on so I should understand it. The payoff wasn’t just fixing the bug, it was learning enough to know how to fix it.

I _love_ Strong Towns but I want to push back against this article.

Strong Towns is a leading voice on YIMBY, but this is reminiscent of the common arguments I hear from NIMBY folks..."they shouldn't be allowed to build here because ____" is definitionally NIMBY.

While I don't love Dollar General or shop there very often, I have a hard time understanding why it's a "swindle." The reason people shop there is because the store provides what they need at a lower price. If I can buy the same milk for $3 from DG or $4.50 from Grandma's Really Adorable Milk Store, I'm going to Dollar General. No swindle here...that's just a better deal.

> “We feed off of what they don’t do, they can’t do,” the owner of Mike’s Hardware & Supply explained.

Great! Do that. Outcompete them on what makes you distinctly valuable, and if you're right, people will pick you. I go to my hardware store instead of Lowes because I know there's a 70-year-old guy who knows more about my project than I do, and I'm happy to pay an extra couple dollars to ask him questions while I buy a socket wrench.

Now, I get that government subsidies tilt the scales...but rather than yell that it's unfair, let's elect politicians who are ready to build incentive programs to provide similar (or better) subsidies for small businesses who provide fresh food and other goods which are crucial for local communities. Small businesses may need to gather together in some cooperative or union-type organization in order to present a more unified bloc to the political class but that's just the nature of living in a big country.

Big business is here to stay, whether we like it or not. And people are _choosing_ those businesses because they think they provide good value for money.

To my eye that looks essentially like a tie, which may seem like not that big of a deal.

When I run compilation and multithreaded integration tests on my chonky AMD Ryzen 9 5950X (16 cores, 32 threads) on Ubuntu 24.04, and on my 2020 M1 Mac mini (8 cores), *the mini keeps up*. It’s quite impressive.

> It's increasingly hard to watch mainstream films with practical effects or animal actors. Even though most audiences would vastly prefer the real deal, they just put up with it.

I (mostly) prefer today's special effects to the ones in the past. The old ones would take me out of the moment, because I'd notice that it was a special effect. (IE, in the original Star Wars movies you can see the matt lines on VHS, and the strings on the C3P0 puppet in the desert. Really distracting.)

---

A few more points:

A lot of the article reminds me of how recording artists would complain, in the 2000s and 2010s, that they would put a lot of effort into a recording, and then most people were listening to it on a sh*tty MP3. The recording artists didn't understand their audiences. It's hard to know if it's a case where the video game artists don't understand the audiences, or the tool (AI) really isn't bringing value to the process.

> It's easy to envision a similar future where the budget for art simply isn't there in most offerings, and we're left praising mediocre holdout auteurs for their simple adherence to traditional form

I'm not sure what you mean by that.

This would be useful beyond getting in and out of customs too. For instance, most people don't want to carry around a work phone and a personal phone, so we end up mixing two personas on one device, and it gets awful. For instance I keep two 2fa apps, one for work stuff and one for personal stuff. It would be so much easier if I could have a separate login that showed just my work apps. Like ... wouldn't it be nice to only have to see work slacks when you log in using a work persona?

> Bringing “manufacturing back to the US” is a fool’s errand. The future of manufacturing is automation, not jobs.

That’s probably correct. But the current trajectory means that China will have the robot-operated factories, not the US. What do you anticipate the US will do to obtain goods from those Chinese factories? Especially when AI stands poised to obsolete a lot of the white collar jobs where the US still retains a competitive edge?

You can’t treat the reserve dollar as something that will perpetually defy physics. The pound used to be the world’s reserve currency not too long ago. There’s no reason for the world to continue flocking to dollars when other economies surpass the US.

> I see the same pattern for movie theaters. They used to be independent mostly with affordable prices.

Movie theaters used to be extremely integrated with the movie studios. You had to go to a Paramount movie theater to see a Paramount movie. Antitrust laws broke that up until just recently Sony bought Alamo Drafthouse.

But that said, there's still a lot of different brands of movie theaters around me. On top of the normal Cinemark and AMC there's also Alamo Drafthouse, Studio Movie Grill, B&B, Angelika, and several other single-location theaters.
