Neat, I was not aware of this mechanism. Is there any way to get map (tile) data from CoMaps into another app?

The issue is that we change our map file "format" with nearly every release, and handling that without crashing is already a job. For example if we add, say, bomb shelters to the map, an older app using that newer data will have access to it but no idea how to render it, which can cause problems (crashing, errors, blanks, etc.) So we have very specific versioning on a per-map-release / app-release basis, and that's just our project. We've already diverged from Organic Maps and even moreso from the (corporate, closed) Maps.me and living on a totally different data format planet from OsmAnd and Magic Earth. So it's a nice idea but extremely hard in practice.

There are converters between different OSM formats and other formats (Garmin comes to mind). It depends on the target. E.g. here: https://www.mapfileconverter.com/free-gis-conversion-tools

Thanks, but I was interested more in the cross-app communication aspect rather than the data formats ( https://codeberg.org/comaps/comaps/wiki/Content-Provider ).

I once looked into building an app which piggybacked on CoMaps/OSMAnd's data (saving the user from having two copies of their maps, and me from having to duplicate the UI to manage them), but found that in modern Android it was basically impossible for even the user to access data/files that "belong" to an app, without rooting the device.


Thanks for the reminder that ContentProvider is the Android term I couldn't remember when I wrote my other comment here.

And the reminder that I should have added this to my list:

3. A ContentProvider app for OSM map data, so that apps can share the same offline map data.


You could probably score 100% on ARC 3 if you were motivated enough. I find some of the current problems to be kind of like Chess - mechanically simple, and ~solvable, but it's difficult to force myself to think at length about a monotonous and meaningless problem. The machines do have an advantage on the "energy" front; they've become almost psychotically persistent (and don't get tired after too many prompts).

Anyway yes I think we've had AGI for a while now, even if the GI doesn't quite match up with what we expect from a human.


The Glacial National Park referenced by GP is in Montana; you were perhaps at Glacier Bay National Park.

Regardless, some beautiful photos, thanks for sharing


Bedrock seems to have stopped adding new open-weights models, and mostly only has Anthropic and OpenAI stuff now. You can get Qwen 3.8 directly from Alibaba: https://www.qwencloud.com (proprietary variant) or from DigitalOcean (this variant, probably also from others soon).

On your 5090 you could easily run a smaller model like Qwen 3.6 27B: https://huggingface.co/collections/Qwen/qwen36 or Gemma 4 etc., or as mentioned there's a Qwen 3.8 27B coming out in a few days.


What does the number before the B signify?


Its number of parameters. The 'B' is billions. If you have bf16 weights each parameter would be 16 bits.


On the first point, I think it's a search of boat names, not boats - they're deduplicated.


Sure, but if you click on the boat called "Freedom", it shows you the data of one specific boat, not "there are X boats with this name". So I still think it's inconsistent...


There are 101 boats called freedom but they're all the same boat because they're not de-duplicated.


Also (mentioned by Tom), this elastic-powered supersonic trebuchet is an excellent video: https://www.youtube.com/watch?v=gdXOS-B0Bus


That device is so much more scary! Both really demonstrate the ridiculous amount of energy stored in a pinch of gun powder. And I presume gun powder is quite inefficient at driving the projectile, too.


I’m not sure dropping 50 kg 4 feet… is my idea of demonstrating the ridiculous amount of energy stored in something…


Well, let that drop on your feet. Or have those fat rubber bands slap you in the face... The small pinch of powder in a cartridge got the same punch.

It's not a nuclear bomb obviously, but I feel you would be just as dismissive, anyway.


This would qualify more as a Ballista than a trebuchet

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


No it wouldn't... the projectile is still launched by the same angular motion of an arm and a sling basket the power for the rotation just comes from a different source.

the "shot you've been waiting for" was sort of anticlimactic, but the two plywood arm shots after show what it actually sounds like. I think the grass and tree dulled the sound a lot on the metal arm.

I actually have a camera that can shoot that at high speed (1200fps), but i'm sure other people have better cameras these days, mine has very low resolution.


Slow Mo Guys have a Phantom that rocks up around 1.5 million FPS. They've used it to show how glass cracks etc. when you get to that speed though, you need a LOT of light, and a very low resolution.


i dont imagine the low resolution is per se essential the same way the light is. you could maybe figure out ways of syncing the data collection to match each other at that high of speed


It is because the main limitation for high speed digital video is the bandwidth of the pipeline from sensor to storage. Lowering the resolution increases the number of frames you can shove through the X Gbps pipe between the photons hitting the sensor and the highspeed memory the camera is buffering into.

Scientific research systems like the SCARF achieve 156.3 trillion fps but at greatly reduced spatial resolutions.


Is that the "nuclear potato cannon" one?


Most phones won't boot without the battery. Obvious workaround is to connect a power supply (and large cap) directly to the BMS, but in my experience most phones will shut themselves down when they think they've drawn more than the capacity of their battery, even if the voltage is still high. You can sometimes get around that by rebooting the device every couple of hours (and there might be a software/firmware fix in some cases?), but it's a lot less annoying to just accept a small risk of a house fire.


You could throw the phone in an ammo canister, if the wifi AP is close enough. When I was building hobby quadcopters, which requires several ~half-pound batteries that are a chemistry optimized for maximum power density, a lot of guys recommended steel ammo cans for battery storage.


I’m also an ammo-case-for-drone-batteries guy but they aren’t running and don’t generate heat. A phone would cook right?


Depends on how well the canister insulates it. Steel conducts heat fairly well; it'd get hot inside but I'd guess some airflow around the canister would probably keep it from getting hot enough to cook the electronics. (definitely don't take my word for it lol)


Phones are very low power, likely just a slightly warm spot on the can that radiates, conducts, and convects the heat out. You could also use one of those peltier module phone coolers, to ensure the heat gets out of the phone and into the air faster.


That’s seems like a lot of work when a $200 box will solve it all without the need lol


in a steady state closed container a peltier cooler will just increase total heat and not help your phone.


> but it's a lot less annoying to just accept a small risk of a house fire.

Agree! But do get one or two of those "small automatic fire extinguisher" or whatever they are, that you can attach on stuff, for electrical panels and what not, and put right next to it together with a traditional fire alarm, and you're good to go :)


No extinguisher can stop a lithium battery fire.

Putting the phone into a metal box, and the box, onto something not flammable, would help.


> No extinguisher can stop a lithium battery fire.

Maybe eventually everything around it can be so wet/burned out that the battery fire slowly just ends? The room would probably be fucked anyway...


Suspend metal box in larger metal box?


How many phones have you tested this with?


I don't think it's been shrunk, I think there just aren't enough high karma posts to fill the default (filtered) page. Old posts fall off due to karma decay and low quality posts get flagged or hidden by mods. I've seen it several times before (and thought to myself that it would be a good time to post).

As mentioned there's also asknew: https://news.ycombinator.com/asknew



With an unlimited budget, Kimi K3 (which is quite comparable to this Qwen Max imo). With a normal budget/a PC you might already have, probably Qwen 3.6 27B.
