  • Partially. Inverters providing virtual inertia is good but has the problem of still being active and reactive. It helps and is cheaper and more efficient than flywheels.

    Flywheels and turbines however provide a very sticky frequency. They help out a lot with stability and give inverters time to respond.

    Think balancing a stick on your hand vs anchoring it in clay.

    If we take enough turbines off line we are still probably going to need some mechanical power stabilization no matter how inefficient.

    But yeah I think we are going to see a blend using as much electrical and as little mechanical as possible.





  • If you are trying to steel credentials from people with power and money passengers in first class are a good target.

    Where else are you going to find a cluster of people like that that are using the wifi and are going to be there for hours. It’s about as optimal as I can think of.

    Even better if you are targeting a spefic company. Just pick flights out of the headquarters for that company.

    If you want to attack say Microsoft pick a flight from Seattle to DC. Pretty good odds of a Microsoft high up being on the flight and wanting to use the wifi for work.



  • It’s Nyquist–Shannon. Norquist is taxes.

    Also frequencies greater than half the sampling rate aren’t lost they fold into lower frequencies unless filtered out.

    But if you think it’s easiser to capture those room acoustics with analog equipment the non linear amplification and distortion of any analog system is going to change the sound just add much if not more then a good digital system.

    So yeah both lose or distort the signal but digital does it in avery predictable way that can be accounted for and it does have a frequency region that it captures precisely. Analog doesn’t.


  • So I got my AA at community college and my bachelors in computer engineering at a university. Other then math and physics there wasn’t a ton of useful classes in CC.

    But if you are going to an ABET accredited school (or similar if outside north america) you are going to learn a lot in university.

    You should learn how to analyze basic RLC circuits. How semiconductors work at a atomic level. How to design basic transistor circuits. Logic gates both design and analysis. Flipflops (the simplest computer). Computer architecture. A programming language or two and some basic assembly. How to use an oscope, logic probe, and multi meter. Basic digital signal processing, fourier transform, and linear controls.

    There is a ton to learn and it’s not stuff you can just pickup on the job.

    Keep at it and good luck.


  • It’s an interesting question as far as dead naming as well. Normally it’s just a dick move or an accident because of old habits. But in the case of people who did important work that might be published under an old name it can be useful to get them the credit.

    I’m a computer engineer so I looked up her work to see if I was familiar with it. I was wondering if I would need to lookup her dead name to find her important work. In her case her big book (which I recognized immediately and have on my shelf) was published after her transition so it wasn’t necessary.

    If it had been written pre transition it would have been a shame to not know she was the author.
