I mean, yes to both. Depending on local political boundary systems, it might be part of the main city or not.

Reasonable commute has a different definition for different people. Some people don't commute for work, so two hours to city center is fine if they only go a few times a year. Some only commute for work a couple times a week and an hour and a half sucks, but is doable if the housing is better enough on whatever dimension. Some will be able to move their job to the new location.

If the new town has appropriate zoning and desires, a handful of companies in the city center may setup offices there to reduce office costs and attract workers that are in the periphery, instead of making everyone go into the city center.

This definitely happens around Toronto, just from looking at the density of roads on Google Maps. There's plenty of pockets of density in lines out from Toronto, and there's also several named places where there's no clear boundary between the names (there probably is at other levels of detail).

> However, the multiplication of a cracovian by another cracovian is defined differently: the result of multiplying an element from column i of the left cracovian by an element from column j of the right cracovian is a term of the sum in column i and row j of the result.

Am I the only one for whom this crucial explanation didn’t click? Admittedly, I might be stupid.

Wikipedia is a bit more understandable: „The Cracovian product of two matrices, say A and B, is defined by A ∧ B = (B^T)A

I feel the severely increased number of things in our lives -- social connections (former workplaces, schools, kids, church, neighbors, etc), work demands, parenting demands, caring for parents, interests (hobbies, tv shows, ...), modern living (commute, finances, adulting, exercise, property maintenance, ...), etc -- has created so much cognitive load that the only way to "scale" the mind and participate is to leverage tech (social media, online, apps, etc)

how to ease this cognitive load ? I imagine that it is very tempting to accidentally dehumanize others in the pursuit of looking after one's own burdens
Show HN: I scraped 5k Reddit, G2, Capterra and Upwork complaints
by wasayybuildz | 2025-06-20 17:02:27+00:00
I got tired of spending nights researching Reddit threads, G2 rants, Capterra reviews, and Upwork briefs just to spot a real, unsolved problem worth building for. So I wrote a crawler + AI parser that now tracks thousands of live complaints and clusters them into pain point cards. I’m using it to power my own project (StartupIdeaLab), but before I polish anything further I want to test the raw insights with other founders.

If you drop a comment with the niche or industry you’re targeting B2B SaaS, ecommerce tooling, dev productivity, whatever I’ll reply with one genuine pain point my system pulled, plus a quick SaaS idea you could spin up to solve it. No strings attached. If the idea sparks something, great. If you try the tool and bail, even better let me know why the paid plan didn’t feel worth it so I can fix it.

> So yes, the default is to justify why the change must be implemented.

That was done when the plan was proposed (and reviewed/approved by city/state/Federal government).

We're now in the "confirming the benefits" stage. Which is the point of the article we're discussing; those benefits have, indeed, showed up in the stats. As the justifications for the change suggested they would.

Now's the time for opponents to support their pre-implementation allegations of doom and gloom, with concrete evidence now available because it's an actual thing.

This is false, he we the sole person submitting large amounts of code for about a year and was widely praised, until he forked and red hat went nuclear on his account for opposing their corporate goals, he was not kicked out for bad changes or anything of the sort. Trying to revise history on this is malicious.

The people like OA are spreading misinformation because the developer stated everyone was welcome to contribute and would oppose excessive politics. Keep in mind red hat is currently getting sued 3x over for blatantly racist policies which they used to ban other contributors and forced on their managers, they are evil people.

Why do I care what some random guy’s HCL to JSON conversion tool thinks is valid?

Terraform converts HCL to JSON in a different way that makes a lot more sense, and hcldec provided by Hashicorp lets you define your own specification for how you want to use it.

I would like to point out that perfect compatibility with JSON is not a goal nor a requirement of a decent configuration language.

A profoundly wise and great article.

My son is a big kid and is playing high school football. It was not on our radar, so we have begun to navigate these kinds of questions. Like - do you want to play at the next level? What do you even need to do if you would like to? But also the realization of how much money is made off of these kids and how cruel and unforgiving it can be.

You can think of a LLM as a type of lossy compression of knowledge.

With that in mind, is it really surprising that you don’t get the ‘right’ answer out? Any more than if you compress an image with JPEG, a given pixel isn’t the ‘right’ color anymore either?

They’re both close (kinda) at least, which is the point. If you wanted the exact right answer, don’t use lossy compression - it’ll be expensive in other ways though.

> I think that they've done it, this is Meta's iPod

I would love to try these types of devices but there is no way I'd ever give money to Meta or put my personal information into their systems or encourage my friends and family to do so either.

Hopefully Meta puts in a bunch of R&D to see what works in this space and then someone else (Apple?) just copies it.

Yes all 3. It has been weird trying to position/brand this as we started out just going for full-stack Elixir/Phoenix and it became very clear this is already much bigger than a single stack. That said, we wanted to nail a single stack super well to start and the agent is tailored for vibe'd apps atm. I want to introduce a pair mode next for more leveled assistance without having to nag it.

You could absolutely treat phoenix.new as your full dev IDE environment, but I think about it less an IDE, and more a remote runtime where agents get work done that you pop into as needed. Or another way to think about it, the agent doesn't care or need the vscode IDE or xterm. They are purely conveniences for us meaty humans.

For me, something like this is the future of programming. Agents fiddling away and we pop in to see what's going on or work on things they aren't well suited for.

Tidewave is focused on improving your local dev experience while we sit on the infra/remote agent/codex/devin/jules side of the fence. Tidewave also has a MCP server which Phoenix.new could integrate with that runs inside your app itself.

No, I don't need to make assumptions about any of that. It's a complex interplay of factors (like any economic system), and everyone has their own reward function.

I'm just saying that if the marginal driver were still choosing to drive, then the system wouldn't work at all. That seems tautological?

The MTA has to set the price high enough above market that the reduction in demand is X%. Whether someone is driving because of speed, or comfort, or some other factor, the cost has to exceed their personally calculated benefit.

> You can absolutely most definitely do it for nothing but material cost.

> $60k for a house

Where did you build the house? Presuming it's on land you own, how did you come to own the land? If you purchased it, the purchase amount should be included in the cost. If you did not purchase it, consider how lucky you are.

Edit to reply to the dead reply:

I do see the context of this being on already-owned land so my point is moot. Apologies for that. (For what it's worth, I'm not really convinced by the fact that you can get free land where nobody wants to live but that's another matter.)

Maybe, or maybe just have more street cars and trams and such. More walking, and more biking to go from A -> B.

I'm not sure in the case of Manhattan that driverless cars are particularly valuable, and it's very much debatable whether they would be a predictable success for a few reasons.

Inevitably you arrive at a scenario where you have a limited number of them because of course otherwise would be to defeat the purpose of the congestion zone, and then you'll only have certain operators with the right permits able to extract money from moving people. Kind of like the taxi medallion scheme all over again.

One of the best things America could do is to be to reduce reliance and spend on cars. This applies to New York but even moreso to the rest of the country.

I think that's the wrong question to be asking. The people who elected Trump don't want a foreign policy. As much as possible, they want isolationism.

To the degree that we have to deal with other countries, they don't want anything that we'd recognize as "policy". That implies a lot of overhead and complexity that they feel is unnecessary.

Viewed that way, "foreign policy" is an outdated way of thinking. It's an artifact of entrenched, elitist bureaucracies. That's precisely the swamp that Trump was sent to drain.

I happen to think that this is a very bad idea, but if my ideas were so darn great, why didn't my side win the last election?

There are also Republicans who disagree, but they were also part of the bureaucracy to be swept aside. They have to choose whether they want to get on board with the new (better) way of thinking, or become irrelevant.

He stated everyone was welcome regardless of their race or politics. This is only a strongly political stance if you contrast it with Red Hat, whose extremist, racist and illegal discriminatory policies they implemented under the banner of DEI now has them in hot water with 3x workplace discrimination lawsuits. Honestly i don't understand how people can call xlibre political but abide by red hat's active evil.

1 week of work to go from local-only to fly provisioned IDE machines with all the proxying. fly-replay is the unsung hero in this case, that's how we can route the *.phx.run urls to your running dev servers, how we proxy `git push` to phoenix.new to your IDE's git server, and how we frame your app preview within the IDE in a way that works with Safari (cross origin websocket iframes are a no go). We're also doing a bunch of other neat tricks involving object storage, which we'll write about at some point. Feel free to reach out in slack/email if you want to chat more.

I didnt get the explanation of the multiplication. After reading the wikipedia article it made mode sense:

https://en.wikipedia.org/wiki/Cracovian

The Cracovian product of two matrices, say A and B, is defined by

A ∧ B = BT A,

where BT and A are assumed compatible for the common (Cayley) type of matrix multiplication and BT is the transpose of B.

Since (AB)T = BT AT, the products (A ∧ B) ∧ C and A ∧ (B ∧ C) will generally be different; thus, Cracovian multiplication is non-associative.

A good reference how to use them and why they are useful is here (pdf):

A society that causes and/or permits homeless people pooping in the subway is, though.

https://en.wikipedia.org/wiki/Toilets_in_New_York_City

> Compared to other big cities, public bathrooms in New York City are rare, as the 1,100 public restrooms result in a rate of 16 per 100,000 residents. Most public restrooms are located in parks; comparatively few other public spaces, including New York City Subway stations, have public restrooms.

> As of 2022, the New York City Subway has 472 stations, 69 of which have public bathrooms. Several homeless people sued the New York City government and the Metropolitan Transportation Authority (MTA) in 1990, claiming that the city and MTA created a "public nuisance" by failing to provide public toilets. A report by the Legal Action Center for the Homeless, who represented the plaintiffs, noted that of 526 public comfort stations surveyed in parks, almost three-quarters were "either closed, filthy, foul-smelling or without toilet paper and soap." In 2010, there were 133 open restrooms in 81 of the system's 468 stations.

There's a great quote on this: "A developed country is not a place where the poor have cars. It's where the rich use public transportation."

I think the businesses do kind of know their customers.

This is an exaggeration of what (I think) happens: all of their current customers only ever drive there and park in front of their shop. They say oh with no parking I won't come any more. Then they stop coming. They lost all their customers! Everyone who can now safely walk to the shop (who couldn't / wouldn't before for multiple reasons) starts walking there. There are a lot more people who can now safely walk to and patronize the shop, and they do. The shops foot traffic went up by 10x. They still lost all their customers.

I think it's probably good that it's easy for people to walk / bike / bus to this shop, and the shop owner probably does to, but they still may have lost a lot of old customers.

That’s not how it works, especially for Rubin. In practice what it means is much lower statistics on streaky data over time. The streaks are not point sources either, so they have a disproportionate impact. You can deal with this through survey strategy to some extent.

You can almost think of this as something similar to vignetting in the final data products. Certain areas will have lower statistics and especially lower temporal resolution based on the season depending on where they are relative to the horizon near twilight.

So, a single image could be lost, but there is supposed to be 1000 or so good images of that area over the survey, about 100 a year. With the satellites, potentially you’ve now lost 3–8 images a year for any given section of the sky (probably more near the equatorial plane), lowering your statistics of the entire survey 1-10%, depending on the declination.

I’m spitballing numbers, there are actual papers you could read though.

Rubin is “wider, deeper, faster”. This reduces all of those dimensions to some extent, but especially the deeper.

I agree! Yet you said:

so I was confused. But now you've clarified:

> I responded to the most plausible interpretation of what the 2-3000 years of history could have to do

You guessed the argument, responded to it. Fair enough. Now I understand.

I appreciate your explanation. I don't think I agree with your analysis or conclusions, but I am grateful you have explained to me your thought process and haven't used personal attacks on me, so I feel this thread of the discussion was constructive.

Since this is actually the same edition that's been available for at least 7 years, but you still clicked the link, it's very likely you're interested in something along those lines. Consider getting "Concepts, Techniques, and Models of Computer Programming First Edition"[1] by Peter Van Roy and Seif Haridi. Although not exactly cutting edge (2004) and Oz-centric[2], still a great read and, for many, a fresh perspective.

I don't understand how she's using Meta glasses to read print. You mean it's dictating it, or are they prescription? If the former, do you need meta glasses for that? If it's the latter, wouldn't it work with any glasses?

I also don't understand how they're used to locate items around the house. Is there some sort of GPS? Or do you mean it helps by virtue of seeing (e.g. prescription)?

AR glasses will be a hit, no doubt, but I don't see what's so special about glasses with a mic, camera and speaker on them. Seems especially for an older person that it would be more useful getting a phone with a screen and pointing at things and seeing it on a display.

Overall don't disagree with the post too much, but I don't like the example given of speaking to the AI "Charlie".

I work with AI on a daily basis, and frankly I don't think I'll EVER want to just prompt the LLM to do things like craft and send an email autonomously or draft a blog post. Andrej Karpathy's recent talk on programming discussed the generation -> verification loop. For any serious work, you don't want to just rely on AI to generate lots of content (textual, email, etc) without verifying what the AI has done. Maybe in a few decades when we've reached HAL 9000 levels of intelligence and the accuracy is 99.999%, but even then there is some something in me (perhaps neuroticism) where I ALWAYS went to check the content of the email before it is sent. For blog posting, I just want my natural voice to shine, so I would never use an LLM to wholesale write a blog post for me.

But maybe that's just me.

I think you’re agreeing with each other. GP was talking about at the aggregate level where your observation is about the individual specifically. At the aggregate level with traffic reduction you’d think individuals would weigh their money as a shortcut to regain time but they don’t. My personal guess is because Manhattan is not the actual destination, work and home are the destinations, Manhattan is just the environment. Before it was the cost of car maintenance to drive into Manhattan (in the individuals eyes “free”), now it’s car maintenance + $9/day.

>>This only affects multi-millionaires, and even then, your numbers are wrong. The national wealth tax only applies to net worth over €3M. The top rate of 3.5% is only for assets over €10.7M. And some regions like Madrid and Andalusia offer a 100% exemption from the regional tax.

Who do you think is going to build/finance businesses if not people with significant NW? Also central government removed Andalucia's and Madrid's exemptions lately.

>>False. The top income tax bracket is ~47% on earnings over €300K, which is far beyond a "semi-decent" salary here. More importantly, as a foreigner, you can use the "Beckham Law" to pay a flat tax of 24% on your first €600K of income for six years.

Add health care and employer contributions.

>>You're cherry-picking the highest rate again. It's a progressive tax starting at 19%. It only exceeds 25% on gains over €200K. Besides, if your investors are not in Spain, they are taxed in their country of residence under its tax treaties with Spain.

I am "cherry picking" the case that applies to me. If I live in Spain they would take around 4% of my net worth every year just for me being there. That's an expensive proposition.

>>We are not French, we won't scold you for trying to speak English. While not everyone is fluent in rural areas, people will genuinely try their best to help you, even if it's through Google Translate.

Major problem in EU is that we don't have a common language. Teaching English and making it 2nd official language everywhere should be a top priority. Otherwise we will never have the start American companies have. You will not built a big company if you can't hire and work in English. Tech sector won't happen if tech people don't speak a common language. It will not be Spanish/French/German or Polish (my own).

>>You're confusing social life with professional life. Yes, we might be 15 minutes late for a beer, but in a business context, being late is just as unprofessional here as it is in London or New York.

Not my experience sadly.

>>This is just rage bait. What you are describing, someone entering your primary home, is trespassing, a criminal offense. The police will have them evicted within 48 hours. The infamous "okupa" issue applies to properties that are clearly abandoned or second homes left empty for years, not your actual residence.

There are multiple reports of foreigners living in Spain living for vacation and having their house taken away by ocupas.
