    Even accounting for prices, renewable sources are nearly always better. Price just determines how fast your saving/year will have gotten you your invested money back, but in the long run its nearly always better. You shouldnt move back to oil for example because that 20l of oil i need is 0.00005 euro per liter and can keep me warm for a year. Its still wasted money because its used once and gone. The pivot to green or renewables is something that started years ago and is now going faster ( but not fast enough ). It has nothing to do with the lng prices now

    Examples:

    • i gotten a solar panel last year that cost me 500 euros. Not little money. However, it has saved me 400 euros on energy bill in the last year too. If energy prices were lower, it would have taken me longer to get my money back. Higher price and it would take less time. Imagine pricing goes nuts and its suddenly 15€/kW of energy, it doesnt matter. Im still getting energy of the panel.
      I will admit not everyone can do this, and i got in a nice debate with my previous landlord over this. But its an argument i won because the reasons they didnt allow it was … baked air.

    • another fun one is nuclear. Nuclear is renewable because guess what, the nuclear waste is recycable. Even if you dont pass the waste from one facility to a more modern facility ( that can then use it because its waaaaay more efficient ), you end up with other materials. This one needs billions and years to build which is why it hasnt been done in many places. Why would a government nearly do economical suicide to build one ? ( their words, i think its worth it ). But no matter how much it costs, you’ll benefit from it greatly afterwards because guess what : recycable and larger energy output babeh!!

    • electric cars is also often a big one in this debate. But it costs more and charging is expensive. I am not going to deny that, not even close. I can rant all day long on those 2 arguments and why they are what they are and how it sucks. However, if you have an electric car, and can charge at home with maybe… Some solar panels? Wind turbines? Anyway, if you charge it at home you are basically doing all car stuff without using any fuels. No paying for energy and only using once. You take away the source of the energy the car uses ( from fuel to pure electric ) shove it in a way more efficient way of movement (electric motor vs combustion engine which gives of a lot of energy in the form of heat) and you allow for any way for it to be energised. Want to charge it with an engine? Sure, go ahead. Battery pack? Solar? Kid on a bike? All possible. It means the car is free from whatever fuel making it renewable because it can use renewable energy source.

    All of these examples will save everyone time, money, and space in the long run. Going back would never be necessary even if energy would be lower with fuel hehe

    Youre not saying untrue things, but you should see technology connections rant on this and he counters everything you just said hehe.

    The word renewable comes from being able to use something more than once.
    Oil being burned can only be used once, thats it. Do you need resources to make renewable energy sources? Why yes, you do. And you also need to ship it etc. But it comes from the fact it can be used multiple times.

    If i need , for example, 20l of oil to burn a flame for a year i can do that and i can heat myself for a year. Awesome!
    But after that year i cant reuse anything, its all burned up.

    Now if i use that 20l of oil to make myself something that can heat myself for multiple years without additional resource consuming ( bad example, i know, but lets go with it ), you are always better off with this.

    Thats what the discussion is about. Not that you wont need a non-reusable resource, but that using it should result in something reusable that outlives the other resource and keeps going for longer

    This. This is how i feel about ml/llm/ai tech.
    Im going to give a lecture this year about mcp, what it is and what it does, with a live demo of letting an llm see what an application does ( via an reverse engineering api with an mcp endpoint ) and recreate it in .net ( via the build in vscode mcp ).
    That, or i might make an old api to access data, attach some mcp endpoints and let a lmm design some basic ( = aka to be validated and build upon by an actual engineer!! ) structures of the data for migration purposes and maybe even let it migrate some data depending on how my poc goes.

    The tech is cool as hell, but what its used for and how companies throw it against everything, even if it has no added value, is making me puke and hate it so bad…
    Even the way llm’s are trained make me puke. Fuck you all companies out there

    Cache man, its a fun thing. 32k 32 (derp, 32 not 32k) is a common cache line size. Some compilers realise that your data might be hit often and aligns it to a cache line start to make its access fast and easy. So yes, it might allocate more memory than it should need, but then its to align the data to something like a cache line.
    There is also a hardware reasons that might also be the case. I know the wii’s main processor communicates with the co processor over memory locations that should be 32k aligned because of access speed, not only because of cache. Sometimes, more is less :')

    Hell, might even be a cause of instruction speed that loading and handling 32k of data might be faster than a single byte :').

    Then there is also the minimum heap allocation size that might factor in. Though a 32k minimum memory block seems… Excessive xD
