    As someone working in power grid, this is quite horrible. There are reasons why PV panels are installed properly at the houses, which proper disconnects etc. If there is fire and this is just plugged in, there is no way to disconnect them. If there is maintenance on the electricity, it can be danger to the electricians, because even if you disconnect the mains, there is still power.

    Also these panels had very poor cyber security, their IoT platform had a bug that anyone could control them remotely in masses. Bad actor could have caused serious issues in grid level with them.





  • Due to paywall unfortunately not able to read the article. As someone who works with energy production, having “waste heat of 23 atom bombs a day” is incredible stupid and practically misinformation way of describing the energy amount.

    I assume that they used that 9GW as heat energy output, which would be 24h x 9GWh in a day. That is in a day same amount of 23 x 1 kiloton nuke. But even these are same units, they really aren’t comparable. Another is milliseconds, another is full day.

    Yes, venting that amount of energy to waste is insanely stupid, because it should be used to something useful. That amount of heat could be used to heat cities in colder climates (northern US states/Canada/northern Europe etc).

    Unfortunately US/Canada doesn’t do district heating networks like we do here in Nordics. You distribute gas to homes, we distribute hot water. That hot water can be directly taken from any waste heat source.

    Microsoft’s new Espoo data center is going to heat up 60% of one of the largest cities in Finland. This is the only way these data centers make any sense to build. Other ways to do it is just financially and ecologically stupid.




  • I have been doing electrical work on converting two different banks to two different restaurants.

    Oh boy, getting a new cable inside the vault, quite a job.

    On other there was door drawn in the plans from kitchen to office. The workers started doing carving the wall in nice door shape. After 20cm (8 inches), they took longest drill they had onsite, and tested how far they needed to still go. It didn’t come through the other side. After 20 years today, there is door shape 20cm incline in the kitchen.

    It isn’t AI, main way to know is the one guys green gloves stay on even when they are out of sight long periods of time. None of the current models can handle that.

    These robots just have quite powerful motors that control arms/legs, so when it goes wrong, it can easily destroy itself with spectacular fashion.


  • DLSS is machine learning model trained by Nvidia to invent information to rendered game frames. In general there are two ways:

    • You have two frames of game, model makes up third frame between those two frames, to make game run smoother. This has down side that input lag (you press button and it happens on screen) gets longer. But it increases your FPS (frames per second), which looks smoother.
    • model makes up extra detail to the game frame. Previous versions have mainly being AI upscaling. Game renders in smaller resolution (less pixels), and then it is made larger, and model smooths and makes up details that originally wasn’t there.

    Both of these have same downside, they can cause inconsistency between frames, and have flickering etc.

    This is what DLSS 5 now takes to much more heavier “AI filter” level, because it is not anymore upscaling, but it now can add much more detail that originally wasn’t there. But because the model doesn’t have memory, it must always cause issue that the output will always be bit different. Curious to see how they have overcome that, or is it really so that with DLSS5 with every cutscene, the main character looks different.


  • Modern raspberry pi GPIO pins are compatible with floppy disk cable (similar to PATA). I can tell you how much I enjoyed telling about this to my wife, when I pulled one of them from my magical cable drawer, were I have stored one since the 90’s.

    (Just make sure that there isn’t the one blocked pin, otherwise you might break things)

    What will probably happen is that the unit tests will go closed source, which sucks because it makes verifying things harder for non maintainers.

    With unit tests people can burn down a forest and use billion tokens to recreate same FOSS project that gives green on all unit tests, and if unit tests are enough to cover things, it will be “good enough” replica.


  • They will just do IPO and get trillion dollar valuation, and poof, they are profitable.

    Ad-apalypse is coming, they will squeeze all the pennies from your data and prompts. Personalized ad response to prompt.

    If you have no soul, get ready to buy malware ads to bad JS libraries suggested by AI, filled with crypto miners and crypto stealers
