Ah, yes okay. I think the odds are that's the way it'll go probably and it could be a good thing.

I'm sure it is and I bet it also depends on the tasks, but I think Claude is pretty good. Today I've use 6% of my weekly total and 8% of my Fable - and that's dealt with some fairly complex reasoning rather than coding itself. I can keep tabs - but maybe that was different with chat? TBH I think what I get for my subscription is pretty good - I've hit my paywall only a couple of times but then in fairness I'm usually due a break anyway so I consider it a health check 😊. I doubt they'll offer it for free, even if it would be amazing if they did.

Interesting, I was looking at my usage stats and despite doing some fairly heavy work - I've only used about 25% of my weekly limit. What I did notice though is that I was using Sonnet 5 for the thinking and generating promps but in VSCode I was still on Opus, so I wonder whether that has got anything to do with it? What's interesting is that on Claude website about choosing model it says that Opus uses more of your rate limit but in VSCode Claude Code model selection, it says that Opus gets 2 x Sonnet usage. A bit confusing really. I'm going to give all of the models a little try but I don't think I've got anything complex enough to really test Fable right now. But maybe I'll think of something for my free Fable trial expires.

You're not feeling lonely are you? I've been away and then just too busy with other distractions! I think I might have hinted at this one a while ago, but you were single track on ChatGPT plus a few other local models to listen at the time. Where have you been? 😉 All looks (expletive deleted)ing awesome I have to say. I've just been sorting the workflow with Claude Sonnet 5 and then Claude Code and now I'm genuinely not having to look at code any more either, just copy & paste the prompts and off we go. Did 2 days of coding and not a single bug from the new code - it just highlighted bugs in the existing code, but solved so easily, even if Claude did tie itself in knots because it forgot to read and obey my dev principles instructions - but it realised and apologised for this.. It continuously blows me away. I'm beginning to create a list of ideas for things to build, but Claude code then tells me off for not staying focused on what we're doing. I get it. I've spent my life doing what others thought were stupid projects just because I thought they'd be interesting and fun and I wanted to see where they'd take me. No need for any other reason IMHO.

I didn't say that it didn't. It's just that science has to recognise when the lense through which it is looking is inadequate - which is part of the philosophy of science. Saying that reductionism always yields the truth ignores the fact that a single component can be quite different when it is viewed in isolation as a constituent part compared to when it is in dynamic relation to many other, different, dynamic constituent parts. Therefore, what you claim to be truth or even real, from one perspective isn't from the other.

But the existence of Cargo Cult Science doesn't prove anything about environmental change, nor whether the science is right, or going in the right or wrong direction. Here's another physicist's perspective, which doesn't question the underlying science (but she does regularly question a lot about the current world of physics and science):

No, it isn't. It's based in complexity, which physics seriously struggles with and the reductionist approach it has long held so dear really doesn't cope. This typical reductionism is exactly mirrored by your claim that it's based on basic physics and fundamental components - but the behaviours of the systems are based on their complex and dynamic relations. But, you've also kind of proved my point - you're making a statement that one small fraction of science is true science which indicates to me a misunderstanding of the scientific method and the philosophy of science itself. Science is actually about continually questioning whether what we think as true is really true and so moving forwards and that by definition this also involves questioning the basis upon which we think we know something. That is the scientific method.

I think you're flying a bit close to the wind here. You said you studied the philosophy of science? This includes epistemology and ontology - there is not just one narrow fixed definition of these, which is what you seem to be suggesting. But also the philosophy of science is about exploring the relationship between science and what we consider to be truth, and certainly not anything like that certain sciences are real - which implies they have exclusivity over what is true, which of course they don't, it would be pretty naive and ignorant to suggest they did. 😉 I'd also suggest that being fixed about what is real, is pretty non-scientific to begin with and ignores the very important metaphysical component inherent the philosophy of science. 😉

It depends on whether you're looking to rely on them or not. The problem with temp gauges at the manifold is that the return one will show a combined return temp from all loops so you don't know if your individual loops are running at the correct dT. The flow one is okay, but personally I have a mixture of clip on k-type used with a digital thermometer and some bluetooth ones that provide datalogging back to a specific app - at least for commissioning and maintenance use - so each loop can be properly balanced.

TBH, I think the article by Evan Davis was pretty fairly balanced, and the BBC the other BBC one is slightly cheaky as it doesn't properly go into why the ECO4 grant was amended. The reality is that if the heat pump is going in as a retrofit, the overall costs of the system are very high - and no, unlike many incorrect claims here on this forum, this is not purely down to grant harvesting. But figures like Dale Vince aren't helping by saying things like heat pumps don't work like they say they do, as he did in an interview yesterday, doesn't help at all. These are the kinds of statements that need clarifying, but just like the whole Net Zero thing, the general and popular coverage is fairly toxic and I have to say the industry isn't helping itself greatly right now.

I was driving through France twice last week and on one of the journeys the exterior temperature was shown as 41C - the a/c in the van couldn't cope and it was just getting hotter and hotter inside but it was a shock to the system to get out on a quick break.

Keeps on coming back to this doesn't it? Domain knowledge is first key, second is then how to translate that into useful prompts. I was playing with DeepSeek this morning and pretty blown away by how far it's come in a few months. It was fascinating that after inputing some questions, I explained I had domain knowledge and it they said that totally changed the situation and provided a much more complex and deep answer that someone without the knowledge or experience wouldn't understand. It's crazy this. I now want to go explore the smaller, more efficient models that are designed for particular tasks as that really seems like the way to go.

Loads of installs still use an s-plan setup and manufacturers still provide schematics for this with a bypass for over-run with both valves closed. 🤷‍♂️

Like all things it depends on the numbers and what you actually mean by cooling - are you looking for air conditioning type cooling, or just tempering the excess heat during heat waves? A slab, for example, has a very slow response time, but a cool slab is very good at soaking up direct solar gains due to thermal mass. But also, using slab cooling will increase room humidity and over a longer period can cause discomfort as a result, so sufficient ventilation is essential. Running your heat pump at say 7-8C through fan coils is also much less efficient than running at 16-18C through a slab at which temperatures you'll see efficiencies on a par with low flow temp heating on the same unit. It's all a question of balance and what makes most sense for your architecture and needs.

Stop it both of you! You're going to end up pulling me totally off course now. I'm eyeing up my son's old Lenovo gaming laptop that I just wiped and installed Linux onto - it's almost too tempting....
