Sharing a project I have been working on called Third Eye. It does visual geolocation. Given a video, it figures out where it was filmed using only the image content, and draws the route on a map. Pipeline in short: per frame place recognition against a street imagery index a trajectory search that stitches the frames into one coherent path a geometric verification step to catch false matches per frame confidence so weak frames are flagged, not faked I ran it on real dashcam footage and it traced the route quite well. Cross domain matching like this is genuinely hard, so a fair amount of the work went into making it honest about uncertainty. Keen to hear feedback on the matching and trajectory side. Video Demo: https://youtu.be/U3sItFlvq6E?si=-KJrwb0gSlk-GxVH The Index was covering a 12KM2 Area around NYC. submitted by /u/Ok-Apricot956 [link] [Kommentare]
Capital won't save you from disempowerment.
After enough cycles you lose track of which exchange or lender blew up when, so I went back and put the major custody failures from 2014 to 2023 into one timeline with the actual figures. Running through them: Mt. Gox (2014): around 850,000 BTC gone. It wasn't a dramatic hack, the coins drained out over years behind balances that were simply faked. Anyone with funds on it saw no repayment until 2024. QuadrigaCX (2018): the CEO died and the company claimed he was the only one who could access the cold wallets, so ~CAD 169M was supposedly stuck. Then the auditors looked, and the wallets had been empty for eight months before he died. The Ontario regulator called it a Ponzi. 2022, the whole cascade: Three Arrows Capital (a hedge fund) over-leveraged itself into the ground and defaulted on the lenders that were funding it with customer deposits. Celsius, Voyager, BlockFi, and Genesis went down behind it inside about eight months. The "earn yield on your crypto" products had been lending those deposits into that leverage the entire time. FTX (2022): roughly $8B hole, customer funds routed to Alameda, SBF got 25 years. One detail worth knowing if you had money there: the estate is repaying creditors over 100%, but in dollars valued at the November 2022 petition date, when BTC was around $16k. It later ran past $90k, so the recovery measured in actual coins is far below what people lost. The annoying part is how little it changes from one to the next. The deposits were never just sitting there, you had no way to verify the custody, and when it broke you were an unsecured creditor in a bankruptcy instead of someone who owned coins. We have to talk about the other side too, because "just self-custody" isn't free advice. You need exchanges to actually buy and sell. Lose your seed phrase and there's no support line and no court to recover it. Some people are genuinely better off with a regulated, insured custodian.

The value comes from the manufactured perception of scarcity. You could theoretically trade it directly for goods or services, but nobody ever does. It only ever gets traded for fiat currency. You can really only ever buy them with fiat currency and sell them for fiat currency. Most people don't buy them because they think it's actually useful for anything, they only buy because historically they go up in value and they're pretty sure that'll be true forever. People tell you to buy as much as you can, and never sell because the longer you sit on it, the more it'll be worth someday. The value doesn't come from actually being intrinsically useful or worth anything. They're worth far more than other products of equal or better quality, only because for unknown reasons people have decided that it is. You can make your own at home, but it's very unlikely they'll be worth more than you spent making them. Am I talking about bitcoins or baseball cards? submitted by /u/Asleep_Onion [link] [Kommentare]
I’m working with a dataset inventory of around 500K hours, including egocentric and real-world robot-training footage. I’m curious what formats robotics teams currently need most—manipulation, household tasks, teleoperation, or something else? Comment below or PM me if you’d like to see samples. submitted by /u/WideAmbition1964 [link] [Kommentare]
How do you handle optical-flow dropout in GPS-denied tunnels? Been poking at navigation for tight indoor/underground spaces (tunnels, under bridges) where GPS just drops and there's nothing to fall back on. The annoying part is optical flow basically dies in there: bare concrete, repeating geometry, almost nothing to lock onto. Ends up being mostly lidar plus an illuminated camera doing the work. Testing it in sim first for obvious reasons (not keen on flying real hardware into a concrete wall to find the failure modes). Running it on UE5 with PX4/ArduPilot in the loop. For those who've flown GPS-denied in feature-poor spaces: do you just lean harder on lidar, or is there a VIO setup that actually holds up when the visual texture is that poor? Curious what's worked. submitted by /u/AlexThunderRex [link] [Kommentare]
It’s been 10+ years and crypto/ btc has not proven it self to be useful other than to buy low and sell it to the next person at a higher price hoping the narrative causes the price to rise. 99.99% of people that buy crypto only buy to ope to sell it to the next person at a higher price that’s all it has become . Stocks , realestate other assets classes actually produce some good or service but crypto does nothing …. Look at ADA and Charles lol , poly-GON 🤣🫵🤡. Hope to buy low sell high and bounce . submitted by /u/ozera202 [link] [Kommentare]
