Hello everyone. I've been lurking around here, hopeful that some day I may be able to afford a 3D scanner. I have a really nice laptop, with up 64GB of memory that could work as up to 63.5GB of RAM or 48GB of VRAM, but it has no NVIDIA hardware (a Strix Halo machine). I also have a desktop with a 3060 GPU (12GB one). I've read that many 3D scanning software requires NVIDIA hardware for CUDA parallel computing, which turns the scan into a 3D model. Does any of the software offer a "raw data" model capture for processing in another machine? It would be really cool to be able to do so, even if the raw data file is huge.

TIA

Hello everyone. I've (24M) decided to start studying Japanese as a second foreign language (third if we count French, but it's been almost 7 years since I last studied it). I've received a basic Hiragana and Katakana sheet from the academy to start studying and memorizing the syllables until I start the course. Just wanted to say it.

It'll be nice to learn it

Hello everyone. I'm working on a project that is going to have multiple emitters and 1 receiver. For phase 1, I want the emitters as dumb as possible, so they're emitting a "zero" signal (the signal won't hold any valuable data) and use RSSI to measure the distance to the emitter.

I've done some research, and I've found out that using anything in 2.4 GHz with RSSI is a bad idea, as antenna obstruction makes it data unusable, especially on a device that will be attached to a limb. If I use <1GHz RF, I've read there should be no problem.

I would like to know what's the practical limit when RSSI measurement becomes unreliable, as I have found no info on 1 to 2 GHz range, so I'd like to know if I can do some low to mid 1GHz frequencies (for example 1.3 to 1.5 GHz)

On future phases the emitters could get more compute and use a "Fine Timing Measurement" equivalent algorithm to open the possibility to higher frequencies and avoid band interferences, but now I want to concentrate on the receiver as a device and know that the algorithm using the distance data works well.

Any help is appreciated.

TIA

Hello everyone. I've wondered if you have ever thought of the kindle paying for itself through your reading habits. I've done it through the metric of savings on digital vs physical. Last Sunday, may 17th, mine paid for itself after 4 months and 1 week, with a bit over 40 books. As of right now, I am working my way through to see how much money I can save on a year

I gave a second chance to Google after last Christmas failure on Gemini for android auto. It failed once again.

Basically, the company that spies even on how much water you consume decided that the AI supposed to be your assistant shouldn't have access to your user tagged locations (locations you save with the name you want)

I tried once again, it failed catastrophically. I decided to try and reason with the AI to see if there's an easy way to solve this. The "easy" way is to have to type them all the locations so it can remember them.

Google, you're as useful as a cooler on Alaska

Hello everyone. I'm looking for some earbuds that I want to use while sleeping. I'd like them to have a silicone tips that cover the inside of the zone, similar to Redmagic TWS (image below) as I find that type most comfortable. They don't have to be expensive, around the 20 to 30€ mark would be fine. How can I do search for these type of earbuds? Also, if you have some suggestions leave them in a comment. TIA

For those that don't know, TCL has created a new display with a refresh rate as low as 0.01Hz, but also has what I think is the main advertised feature, "local refresh rate zones". Similar to local dimming zones, certain areas of the display are divided so they can have different refresh rates. Their model has 12 zones, but if they could get the number way higher to even local dimming zone numbers, it could be a great feature on laptops and some displays. It could mean greater battery life on certain tasks, and also a better redistribution of the bandwidth to different zones to have greater refresh rates.

I honestly see it as quite the innovation, and could be a great step to new display tech being shown somewhere in the next 4 or 5 years

Hello everyone. I've been curious about this topic for a while, and I would like to know more about how anti-piracy laws are applied (not living in Germany in the forseeable future, just heard about it a couple years ago and wanted to know). From the extent of their law, I assume most sites that allow the illegal download of digital material are blocked in the German Internet (correct me if I'm wrong), so the only available source is torrenting.

I've looked it, and I know that torrenting isn't illegal for something like a Linux ISO or an open-source software that uses torrenting as a distribution method. How does the government know a file is illegal? How do they keep an up-to-date database of illegal files? Do they look at names or content? If a file is compressed/encrypted, do they still know it? Do they look at every packet transmitted through German networks to their national endpoints to see if they're legal?

I just see it, and unless there's a ton of money spent into this there's no way to enforce the law properly imo.

TIA

This may be more of a philosophical question, but it just came to my head.

I know when we talk about the states of matter, we refer to their structure and inter atomic/molecular space. So more than 1 unit is needed, and a mol may be too much, as that would mean that a piece of iron under 50 grams wouldn't technically have a state. So, is there a minimum? How it was determined and what is it? TIA

I just can't see myself buying it for 100€ rn (without trying it on my hands before that). Maybe in the future, but it's expensive. Not especially overpriced (maybe a little), but I can't see it standalone for that money. 60 immediate yes, and 80 a yes with 1 or 2 weeks of convincing. 100 is an "I'll wait for sales". And they've packed lots of goodies on the controller, making it good and very useful, just not good for 100
