  • Btw, ld.so is a symlink to ld-linux-x86-64.so.2 at least on my system. It is an statically linked executable. The ld.so is, in simpler words, an interpreter for the ELF format and you can run it:

    ld.so --help
    

    Entry point address: 0x1d780

    Which seems to be contained in the only executable section segment of ld.so

    LOAD 0x0000000000001000 0x0000000000001000 0x0000000000001000
         0x0000000000028bb5 0x0000000000028bb5  R E    0x1000
    

    Edit: My understanding of this quite shallow; the above is a segment that in this case contains the entirety of the .text section.






  • I’ll just comment about one thing that keeps popping up in the discussions: grid-level storage. There is no such thing yet really that would last a full day cycle, and the 100MW or so units we are building are mostly for frequency stabilization and for buying enough time to turn on a base-load plant when the renewables drop out. I’m not arguing against storage - it is absolutely needed.

    The problem is the scale, which people don’t seem to get. Largest amount of energy we can currently repeatedly store and release is with pumped hydro, and the locations where this is possible are few and far between. Once the batteries reach this level-of-capacity, then we have a possibility to use them as grid-level storage that lasts a few days instead of hours.

    100% Nope: A episode from supernatural, where ghouls half way succeed to eat Sam. (I consider it as the most gruesome horror I have ever seen, and I don’t think I have the stomach to see it ever again. The blood draining is a … no.)

    Yellow brick road on otherhand hits the weird places spot of SCP, which I can’t get enough. (not horror really, but still)



  • Python is just a pile of dicts/hashtables under the hood. Even the basic int type is actually a dict of method names:

    x = 1
    print(dir(x))
    ['__abs__', '__add__', '__and__', '__bool__', '__ceil__', '__class__', '__delattr__', '__dir__', ... ]
    

    PS: I will never get away from the fact that user-space memory addresses are also basically keys into the page table, so it is hashtables all the way down - you cannot escape them.
