Awesome! If you click the top left 'Mode' switch and go to Property, you can buy it :) you just have to pick up and scrap enough trash to get the $5k for it.

I do think 95 and 676 will be in the game more accurately eventually. But it will match the style of the rest of the game. It's a work in progress now but not good enough to ship yet. Love that you said bizarro, feels like i'm on the right track

Hey, thanks. You're pretty much right about highways. I do have a separate working branch that has actual raised highways, but I'm still figuring out the kinks in making it look nice and joining the terrain correctly. Generating accurate entrance/exit ramps has proven to be my kryptonite but I'll get it eventually. I will give the minimap some love when I get back too-- thanks for checking it out

For any Philly ppl here, I've been making this game for a few months: https://cityrider.jpsmaps.com/

Similar concept, but more abstract in terms of art style. I'm pretty close to having the foundation I wanted before adding quests on top; telling a story is the ultimate goal.

Building on top of GIS data is super fun though. Especially since the barrier to entry is so low these days with LLMs. I encourage everyone to give it a shot if your local town/city publishes some data. No need to understand coordinate systems for example, which is nice.

For the game, there's a button to get in without an account so you can play around, but to get the fun mods you will need to play a bit and figure out the trash pick up/scrap at dump mechanic in the game.

(*might be a bit of lag; server needs more ram but on vacation rn!)

jparishy··on As Wisconsin cities flee Flock, its shared camera network loses value
Just one data point, but I've been to many policing conferences since 2020 and I think one of the main drivers of the Flock problem is a disconnect between what the public understands 'crime prevention' to mean, and what is sold to police under the same verbiage. Something I believe strongly is that healthy public safety requires both responsive action and crime prevention. When I talk about this, I will show quadrants with axes for Give/Take and Planned/Responsive, and try to get people to classify their public safety activities to see where they fall. To me it should be somewhat balanced. Everything concentrated in Take/Responsive is an incomplete strategic plan.

However, most tools available to police are designed to be responsive; they help catch a criminal that has already done something bad. This is not crime prevention. Nothing was prevented. Anyone living in an American city knows these cameras don't prevent much.

It is also (unfortunately) a very vendor driven industry. IACP is a big deal each year, and Flock / Axon / Motorola go all out on spending to influence decision makers.

Talking to communities, in my experience, they ask for crime prevention. People want the actual incident to never have occurred in the first place. When vendors go around saying they are solving crime once and for all, but all they deliver is surveillance, it builds distrust. It feels like lying, while the companies themselves get rich on public money.

Then they go on huge PR campaigns to tell the public actually what they're feelings is wrong and they should accept the surveillance. It's silly.

In the policing communications world, people often say trust is built in drops, and lost in buckets.

jparishy··on Compression is prediction
Cool visuals and breakdown. I wrote something in early 2025 about how LLMs seem to be an emergent behavior of lossy compression, but did not have the knowledge or verbiage at the time to get this detailed. In retrospect my writing seems naive and I'm happy to have found this and the Google paper linked inside. To be a fly on the wall in some of the labs, man.

Another thought that came from the same post is that, insofar as we see LLMs as human-style intelligence, they're more like stream of consciousness devices. Essentially incessant talking and buying enough time until you get to a usable answer. I think I associate some subset of intelligence with what you don't say, which is impossible with the SOC-style outputs, so this is something I think about a fair bit.

What could maybe differentiate current gen models from next gen is the ability to call tools modeled within the layers themselves, not externally. I think as far as I understand it, model trainers expect the model to do this itself in a way we don't understand or control, like a version of the bitter lesson. But I posit we can model many determinate tools as NNs themselves and figure out how to get the internal states of the LLM to make use of them during inference, e.g. calculators, indexes, citations. Just an enthusiast though, so grain of salt and all.

I think doing this type of work makes you really respect the game devs that pioneered the genre. a lot of little things matter in terms of making it feel right, whether you're going for realistic or more arcade like.

for my version I leaned arcade: during the race you can jump higher, it gives in game direction hints, and the whole track has a ribbon on it so it's obvious where to go. however, every hour the track changes to a different stretch of Philly roads and it can definitely highlight your point.

The art direction and sense of scale are important, and successful games seem to be quite good at tricking you into thinking the visual scope is bigger than it is, while the smaller/tighter areas are easier to navigate in-game. The real world is surprisingly huge.

(I don't want to spam my game but you can find it in my recent comment history)

jparishy··on The Conservationist Who Turned 40 Terabytes of Public Data into a Video Game
Hey, thanks, that means a lot! Yes, I love my city and I have a long to do list of things to add in honor of it. Do attend.
jparishy··on The Conservationist Who Turned 40 Terabytes of Public Data into a Video Game
This is very cool. I concur on the conclusion that we'll soon see a lot more use of AI coding tools in gov as people discover what can be done with all these existing data sets. Would love to see more resources put into creating and publishing them. I'm sure there's plenty of ways for govs to make their money back on the data these days with some creative licensing.

Tangential, but I'm also a little obsessed with taking municipal data and turning it into something else. Lately I've been building an online open world game built on Philadelphia's terrain. It similarly uses a Philly LIDAR scan, the land use maps, the street data, building lots, and a few other sources to make the game map.

There's a signup but it doesn't validate or anything I just haven't gotten around to making a demo mode. Any fake email will do: https://cityrider.jpsmaps.com/. The general idea is to pick up trash around Philly to power/build other fun things like your jet pack and ramps. Buy properties and customize the facades. Run from Gritty. It's been a blast, and while not conservation, I believe what is effectively a littering PSA to be a worthy output of my time ha.

You can also click on many trees to see what they are, as most are from the Philly Tree Inventory (though more are added to fill out forest areas for style reasons).

jparishy··on Generative AI as Seniority-Biased Technological Change
to me it is just market pressure to exploit the high stress on laborers atm. the level of uncertainty today is only a problem if you don't have a ton of existing capital, which everyone in charge does. so they are insulated and can treat people poorly without repercussions. in a market that prefers short term profits, they will then do this in order to make more money right now.

companies must do this, 'cause if they don't then their competition will (i.e. the pressure)

of course, we can collectively decide to equally value labor and profit, as a symbiotic relationship that incentivizes long term prosperity. but where's the memes in that

jparishy··on The case against social media is stronger than you think
We, consumers online, are sliced and diced on every single dimension possible in order to optimize our clicks for another penny.

As a side benefit, when you do this enough, the pendulum that goes over the middle line for any of these arbitrary-but-improves-clicks division builds momentum until it hits the extremes. On either side-- it doesn't matter, cause it will swing back just as hard, again and again.

As a side benefit the back and forth of the pendulum is very distracting to the public so we do not pay attention to who is pushing it. Billions of collective hours spent fighting with no progress except for the wallets of rich ppl.

It almost feels like a conspiracy but I think it's just the direct, natural result of the vice driven economy we have these days

jparishy··on Americans Lose Faith That Hard Work Leads to Economic Gains, WSJ-NORC Poll Finds
I thought about that, but anecdotally i know many renters addicted to Robinhood. i think housing prices and therefore the cash necessary to get a loan have shifted this divide a bit
jparishy··on Americans Lose Faith That Hard Work Leads to Economic Gains, WSJ-NORC Poll Finds
I agree, I think this is a longer way to say what I was feeling. It's a rigamarole by people with too much money. If they had less money, they wouldn't be able to do it. So at the end of the day the root cause to me is the inequality. it allows special treatment and the ability to manipulate our daily life (through social apps, news, etc) in a way that they are completely insulated from, feeling no pain whatsoever. Huge policy failure to let so few people have so much influence
jparishy··on Americans Lose Faith That Hard Work Leads to Economic Gains, WSJ-NORC Poll Finds
We're on the same wavelength. To me, I find it hard not to think about our explosive growth as a country happening at the same time we refuse to expand representation of the public. These charts are very frustrating to me: https://www.congress.gov/crs-product/IN11547

The people in power do not want to lose control, but clearly have no idea how to manage the scale of what has been built. There's an American leadership crisis going on right now that is hard to ignore, both in public and private life.

jparishy··on Americans Lose Faith That Hard Work Leads to Economic Gains, WSJ-NORC Poll Finds
Wealth inequality is high. High enough you can feel it like a vibe in the air. The richest people in the world are telling everyone to get onboard with technology that is determined to make a lot of those same people's jobs redundant. All with an explicit goal of increasing the price of stock most of those people do not own.

IMO there's two economies, maybe divided by those who participate in the stock market and those who don't. We, Americans, have largely given up trying to improve the lives of people not in the first group. Economies are living, breathing entities and we're just grinding poorer people for fuel so richer people can have another house, another boat, another company. A lot of regular joes are really stressed out about paying rent. The loss in faith is warranted.

jparishy··on An LLM is a lossy encyclopedia
I suspect this ends up being pretty important for the next advancements in AI, specifically LLM-based AI. To me, the transformer architecture is a sort of compression algorithm that is being exploited for emergent behavior at the margins. But I think this is more like stream of consciousness than premeditated thought. Eventually I think we figure out a way to "think" in latent space and have our existing AI models be just the mouthpiece.

In my experience as a human, the more you know about a subject, or even the more you have simply seen content about it, the easier it is to ramble on about it convincingly. It's like a mirroring skill, and it does not actually mean you understand what you're saying.

LLMs seem to do the same thing, I think. At scale this is widely useful, though, I am not discounting it. Just think it's an order of magnitude below what's possible and all this talk of existing stream-of-consciousness-like LLMs creating AGI seems like a miss

jparishy··on In 2025, venture capital can't pretend everything is fine any more
IMO the best innovations tend to happen when someone has their hands bound and has no other choices but to figure out a new way or die. Now seems like an incredible time for new models and startup paradigms.

To me I think VC's figured out a way to market a very specific way to build companies and convinced a lot of people it's the only way for 20-ish years. Then there was this sort of shift to selling to enterprise, I think because B2C got harder and easy money was the goal. By then a lot of enterprise design makers were probably in the networks of the people selling. There's a meme about YC-of-late being mostly companies that sell shovels to each other.

But when you optimize for enterprise, I think you end up losing a lot of diversity of opinion in where the value comes from, which leads to top-heavy companies.

My main issue is that after the ZIRP era I don't believe the money is gone or unavailable. It just seems to be hoarded for some reason. There is astronomical wealth out there that could be used for trying new economic models that compete with the last generation of VCs. But it isn't happening.

Maybe the next era of VC decision makers, the ones who themselves were funded on big bets, just don't have the same appetite for risk? Or maybe the era of "developing your brand" has made them not want to share their success? I'm not sure but it's weird to me.

jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
Okay friend, I don’t think I’ll continue this but I hope one of us is right and the movie industry flourishes
jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
Then you might be missing it as it’s a huge huge issue for below the line workers (actors are part of the package we’re shipping out to other countries)
jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
my view of capitalism is that you can't remove the market. it will exist with or without you, so if you have some control you should incentivize the things that are better for everyone.

To me I think it's possible for Netflix and Amazon and whoever to exist and make a lot of money, but also not have nation-state level power. The latter is something we haven't decided we want yet, but I think we'll come around. If there were even just very small controls (that worked) on the size of a company, or how many industries it can go into, then things would look differently. But when we let so few companies consolidate so much power through money, the status quo is a pretty natural outcome. Imagine a world where there were regional amazon.com's, because we just decided at some point they got too big. Same for google. We'd have actual competition. Tech enables market consolidation in ways we didn't expect and we have to do some actual work to fix it.

jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
The "tariff" we're talking about here would be for where the labor comes from. If a EU film company is choosing to film in the US instead of at home for cost reasons, then sure they can put a tariff on that somehow to keep it local. I don't think that's happening in any meaningful way, but it is in the reverse to the detriment of thousands and thousands of local jobs in LA, ATL, NY, etc.
jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
you can see everyone willfully ignoring this here, which makes me nervous about actually solving this problem long term. I used to dream of screenwriting and that dream is almost certainly dead but I'd like to see others have a chance. It looks bleak now
jparishy··on Trump announces 100% tariffs on movies ‘produced in foreign lands’
i don't ask ppl who they voted for because i've learned it's not a good signal on whether they are nice or a good person. life is complicated. i didn't vote for trump though, so at least this village idiot has a clean conscience and just isn't interested in reliving 2017
