I’ve been exploring coffee and came across this interesting news about “co-fermented coffee”

https://www.home-barista.com/knockbox/discussion-undocumented-infusion-in-green-roasted-coffee-t102005-230.html#p1079794

So in a nutshell, the claim is that you can take green coffee beans and ferment them with some other food item such as spices or fruit, and this process will in turn affect the flavour of the coffee after you roast it and brew it.

Full disclosure, I’ve never heard of co-fermented coffee before. To the best of my knowledge I have never had it before.

The controversy appears to be that perhaps on some or even all cases, the co-fermentation is being augmented or even faked by the addition of glycol and artificial flavours. The suspicion is that typical flavours that are being claimed shouldn’t be stable at the temperatures used in roasting coffee. They also shouldn’t be identifiably the same flavours as the fruit that go in, yet you have lychee co-ferments that apparently taste like lychee, mango co-ferments that taste like mango, and so on.

I’m curious how this all came about. I assume initially co-fermentation was a purely natural process. It sounds like a super obvious thing to attempt. Now we apparently see widespread evidence of chemical additives. Maybe it is in response to instability of the process? Did it ever work as claimed, and did these tests possibly only target the most egregious flavour profiles which therefore found the artificial flavours while not testing the milder and natural variants? I’m sure there are many questions since this seems like an early stage of examination.

So my question is, tilderinos, what’s your take? Is this just gatekeeping, is this fraud on the consumer, do we need certification ala sparkling wine vs champagne for processes, is this possibly just a good and useful evolution of coffee processing?

The survey has been closed and the results are in!

Thank you all again for participating! As mentioned in the original post, this will be the last survey for a little while! On August 2nd however I'll be back with the vote for the next surveys we'll do. :D

I've been thinking about getting into cast iron cooking. I need a new skillet, and I've seen recommendations for cast iron, but some things seem daunting:

• Seasoning. How bad is it really? Did you purchase a pre-seasoned pan and just cook with it? Do you re-season occasionally? How often? What oil do you use? What is your process?
• Cleaning. How do you clean your skillet? Soap and water? How do you know when you are done cleaning? What materials do you use?
• Unknowns. What did you not know until you started cooking with cast iron? Any surprise benefits/costs?

Have any of you used cast iron, then returned to Teflon or stainless steel after being disappointed in the experience? What are the biggest differences between cooking with cast iron and other materials?

Considering that non-stick manufacturing poses environmental risks, and iron may provide a net positive effect for folks needing more iron in their diet, it seems like this is a natural way to go.

Tildes is a very serious site, where we discuss very serious matters like steam machine, ipo and fathers. Tags culled from the highest voted topics from the last seven days, if anyone was alert.

But one of my favourite tags happens to be offbeat! Taking its original inspiration from Sir Nils Olav III, this thread is looking for any far-fetched offbeat stories lurking in the newspapers. It may not deserve its own post, but it deserves a wider audience!

I haven't been closely following the releases of new models and the research papers that sometimes go along with them. So I was wondering: is power consumption ever seriously talked about by OpenAI, Google, Anthropic, and others? Do we get some specific numbers of how much power their models actually consume to produce 100 tokens? The cost of training some of these models? Or we're not yet at that stage yet and nobody cares and at best we can just get really rough estimates based on "trust me bro" tweets by their respective CEO's?

Some time ago, I came across this post. GPT-OSS (2OB, 120B) are meager, yet energy efficient models and I was surprised that the power consumption is still larger than what I had estimated before.

For 120B to generate a 1000 tokens (which is really not a lot) it would take up around 83 Wh of electricity. For context my PC consumes ~100Wh when idling. So it's almost equivalent as leaving my PC on for an hour. Considering that proprietary models are TRILLIONS of parameters and probably not as energy efficient the true power consumption of these models is concerning. Of course, these big data centers do a lot of things to maximize the efficiency that this "test" fails to do. But even if you half the energy consumption it's still significant given their size and their pervasiveness in handling everyday, trivial tasks.

I haven't come across similar posts or studies for newer open source models, so if somebody has, please share.

Also, I don't seem to fully understand how does context size fit into all of this. The larger the context size the more power it would take to produce those 100 tokens?

Greetings everyone. I'm currently in the process of getting a Computer Science degree for two primary reasons. 1.) Because I want to get a stable development job where I'm currently employed, but most importantly to me 2) Because I want to make video games and have the educational credentials to confidently do so.

I know I know, you don't need a computer science degree to create video games, and my program doesn't even teach game development. So I have a long journey ahead learning game dev alongside my program in my own time. Also I have no intentions of working at an actual game company.

So my question today is,

What is a game that you are dying to play, that nobody has made yet?

I'm trying to get some inspiration. It's hard to think about something that truly doesn't exist, because there's so many amazing games already. I'm genuinely curious.

If you're struggling like I am, feel free to list a game that's been made exactly once but no ones been able to reproduce it's genius.

I'll start,

I am DYING to play a factory builder game, but with ARPG gameplay. So Factorio / Dyson Sphere Program meets Diablo 4 & Path Of Exile. I just think this would create such a dopamine addicting game that would be impossible to pull away from if done right. My idea would be to have the factory be the loot crafting mechanic for progressively better armos, while the ARPG is what you use to get the materials needed to craft truly insane gear. Idk, if done right I think this could have legs.

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.
