  • If you’re interested in the systems behind Apollo, go find and read “Digital Apollo”.

    It goes all the way through the project and describes in good detail everything, how they developed the control systems, the computer hardware, how the software was designed, how they implemented one of the first real computer systems project management, all the interactions between astronauts/test pilots who still wanted to “manually fly the lander”, the political back and forth between competing teams, the whole thing.

    It’s a great read if you have a technical mindset.



  • Usually iterations of:

    “Closed and locked due to duplicate of: (question asked 9 years ago about Visual Studio 2011 and Visual Basic, when you’re using VS code '22 and C#)”

    “This seems like an XY problem, what are you really trying to accomplish?”, after a one thousand word post describing in detail exactly what you are trying to accomplish and the many different reasons why you can’t just use #GENERIC_EVERYDAY_METHOD.

    Either that or the quick and dirty method that I want for a one off data conversion that uses standard libraries is heavily down voted and lost while the elaborate, all-cases-considered, 7-third-party-library-using answer becomes the top result.


  • Letting it ring has no impact. They have autodiallers that call, and when someone picks up, only then is that call assigned to someone in the call centre.

    You can often tell this because there is a marked delay in the response to your initial “Hello?”. Long enough that you can reliably just hang up if you don’t hear a response in two seconds.

    If it’s a real person who actually wants to call you and they you call again straight away, you can just shrug off your hang-up as a network issue.




  • True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.

    I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.

    1. Replace CMOS battery.
    2. Get small UPS.
    3. Discover that small UPS’s fail regularly, usually with cooked batteries.
    4. Add maintenance routine for UPS battery.
    5. Begin to wonder if this is really worth it when the rest of the house has no power during an outage.
    6. Get small generator.
    7. Discover that small generators also need maintenance and exercise.
    8. Decide to get a whole house battery backup a-la Tesla Powerwall topped off by solar and a dedicated generator.
    9. Spend 15 years paying this off while wondering if the payback was really worth it, because you can count on one hand the number of extended power outages in that time.
    10. In the end times a roving band of thugs comes around and kills you and strips your house of valuable technology, leaving your homelab setup behind and - sadly - without power. Your dream of unlimited availability has all been for nought.

    Conclusion: just replace the CMOS battery on a yearly basis during planned system downtime.
