My current headphones (Philips TAH8506) are pretty worn out from daily use and recently a bit of plastic on the side cracked, so I figured it'd be a good time to get new ones. Since I know very little about literally any audio hardware it seems a good idea to ask here. Things I'm generally looking for:

• must be over-ear
• decent sound quality; I'm not going to pretend I'm an audiophile, the ones I have now are sufficient so anything as good will do
• connectivity: this is where things get tricky. My current usage is being connected through a jack when using pc and bluetooth when using my phone. These 2 connection modes are a must for me. However, I'd also really like if I was able to connect to pc over 2.4gz with a dongle because bluetooth latency is, frankly, awful. It's mostly why I use a wired connection to pc.
• microphone is not needed (in fact I'd prefer if they don't have one)
• ideally not more than $200
• available in Europe without oversea shipping
• nice to have, but not required:
  • a way to control playback (pause/volume etc) from the headphones. The ones I have now have a touch panel on the right and I occasionally use it (but probably wouldn't miss it)
  • ANC
  • cat-resistant cables (probably no such thing exists)

I'd also appreciate general pointers regarding which brands provide good quality at a decent price to make searching easier. Thanks in advance for any answers!

A little over a year ago I was gifted a Geeetech A30T. I did a couple of prints with it, but haven't had a ton of use for it. My last print was about 5 months ago. I have another print I'm trying to do today, but the printer doesn't extrude. It goes through the motions, but that's it. If I set the nozzle to "Clean" mode, then some extrusion comes out. The load/unload motor for the filament spool works. I've tried unloading/reloading the filament spool. I did a manual level on the bed. Any suggestions on where I may be going wrong?

Spouse and I are trying to get bids from local solar installers and we'd appreciate some crowdsourced knowledge from Tilderinos. Questions first, then some context...

• In the current market, is "no, your equipment can't talk to the Internet" actually an unreasonable demand?
• Is there a term or phrase we should be using to look for, or guide installers towards, solar setups that fully function without Internet access?
• Are there any equipment types -- microinverters, for example -- that definitely will not work due to architecture?
• Are there battery controllers, or central inverters, that are known to play nicely (read: can be expanded later) with batteries from other manufacturers?

For each installer, we start the conversation with "it's essential that the system work entirely offline, without Internet." We're flexible on nearly everything else: system size (probably ~15kW), number of panels, battery, etc. Our first concern is making sure that a 25-year investment is not dependent on some company's cloud servers; secondly, that we're not inverting our dependency graph by making our electric power reliant on the whims of our ISP. There's also the privacy angle. But we're not looking for a totally off-the-grid setup, just trying not to lock ourselves into a bad purchase.

So far, one third of the installers (3/9) have immediately told us we're unreasonable and to just go away. Two others said "sure!" and ghosted us afterwards. One was a little more forthcoming, saying that the equipment requires periodic connections to the manufacturer for monitoring and they couldn't provide a warranty without it. The last two provided bids, but it's difficult to tell if they're telling the truth given the conflicting info we've seen.

I was musing about this recently with the recent models becoming more capable. The core of gen AI is the model, which is trained on a massive dataset. To date, gen AI has improved because the models have become larger, more efficient, the data they are trained on has become better and the software/harnesses around them has improved to help query them.

As I see it, surely the bottleneck will soon become the data they are trained on? If we imagine a scenario where a models could consume an infinite amount of training data, and there is no limit to the training time or quality. The sum of human skill/knowledge is the limiting factor. Gen AI should (in theory) never be able to out preform or push the boundary of the sum of humanity at time of training.

Or, counterpoint, is there enough randomness and speed to iterate that gen AI can actually step change and improve if training times/cost were less prohibitive? Most companies/models today will save good output and feed it back into the next iteration, but right now that's taking months. What if that took minutes?

What do you think?

Is gen AI going to take us to general intelligence?
Will gen AI get to a place where it's "intelligence" and reasoning is actually better than the sum of Humanity?
