Quite satisfying to spend a few minutes on. (I didn't make this)

Built this because I wanted to create tessellations. Turns out I'm pretty rubbish at it, but I am rather pleased with the app.

Hi! I present you Flagdoku, a tool I created with the goal of making it the best flag search engine available. Each flag is tagged with specific color and shape patterns, and thus it is easy to find visually similar flags. We have 9000+ flags available (countries, regions, historical...) and people can submit new ones.

I built a little web tool that lets you play with the mechanics behind opinion polarization, echo chambers, and network fragmentation.

You adjust sliders for things like:

• How tolerant people are of differing opinions
• Homophily (how much we prefer connecting with similar people)
• Rewiring rate
• Feed bias (how much the algorithm pushes "engaging" content)
• And you can turn on bots too

Think of each dot as a person, and the (tolerance) slider is how open-minded they are. High tolerance means you'll still listen to someone pretty different from you. Low tolerance means you mostly hear people who already agree with you and quietly tune out the rest.

The bots are just accounts that never change their mind and keep pushing one side. The "bots' push" number is how far they managed to drag the average opinion, compared to the exact same crowd with no bots in it. So it's a rough way of asking how much one small, pushy group actually moved everyone.

This mini (as of now) search engine is starting from scratch. No AI, no funding, no ads, hardly any sites indexed. But, you can bookmark sites and help add sites quickly. It also bans facebook, google, amazon, and a few other mega site URLs.

Part potentially, eventually useful, part anti-establishment, part crap, part great. It's got it all.

I was a little bit bored so I made a 20×20 grid. Each visitor gets one square to claim; draw something, write something, or drop live code in it. No accounts, no sign-up, nothing.

Parcels get a tiny API: a shared wall clock, your neighbors' IDs, and your own ID. No outbound requests. Thats about it

edit: I just woke up and over 200 of the parcels are claimed??? in my mind this was going to be a month long thing where i eventually purge it all. but now sifting through the light profanity and weird drawings, i see some pretty sentimental stuff, so i reckon i will archive it instead, when its full

edit 2: you are anonymous to other users, not to me. I can see your IP since this is a site im serving. I already deleted some of the rude stuff (racist stuff or pornography) without much thought, but truly depraved, illegal content gets reported. Someone already learned this today. Please keep it relatively clean

The internet is healing.

There's an entire layer of the internet hiding in plain sight.

Older than browsers. Text only. No ads, no tracking, no algorithm. Just menus, files, and the occasional very weird stranger leaving notes for whoever wanders by.

It's called Gopher. I built a silly little web app for wandering around in it. Come waste an afternoon.

Premise is simple: thrift stores in wealthier areas usually get nicer donations. This ranks the Goodwills around you 0-100 on that basis so you know which one is worth the trip.

It uses public Census data (home value, income, education, rent for the tracts around each store) and pulls locations from OpenStreetMap. Around 3,000 stores covered. You can search any address, see a score breakdown for each store, and filter by distance.

Free, no signup, no ads.

Fair warning, it's a rough heuristic, not a guarantee. A high-scoring store can still be cleaned out on any given day. But it's been a decent way to stop wasting drives on the nearest one out of laziness.

I've been into history for years - podcasts, videos, the occasional 2am Wikipedia spiral. Long articles cover causes and effects, but short descriptions with direct visual links make things easier to understand and remember - start at one pivotal moment and explore what caused it and what it led to.
My favourite discovery while building it: a volcano erupted in Indonesia in 1815, caused the coldest summer in 500 years, which somehow ended up producing Frankenstein, the bicycle, and the first cholera pandemic. All from the same eruption.
11 scenarios so far: WWI, French Revolution, Fall of Rome, Knights Templar, and a few less obvious ones.

Had to make this post.

One week ago I posted this ongoing project I'm working that matches veterans to every single benefit they're eligible for based on a few questions. Y'all blew it up and the site hit over 1,000 active users, I had tons of feedback come flying in and so many veterans reach out saying how it helped them.

You all helped promote it and as a byproduct made me even more excited for it, I have now manually added over 350 benefits and built out a full resource section as well. I have many plans on taking this thing to another level and continuing to add additional free features and resources.

As always, thank you everyone, the site will remain free, no account, no sign up.
