  • I think I’ve had it happen once over something like a decade of using them. From what I remember it was because I was running something in the terminal that ignored the signals it was sent, so the laptop didn’t properly go to sleep. Of course, the program ended up failing because a lot of the things it depended on did suspend themselves and that caused major breakage.

    Luckily I noticed a whining sound (fans at maximum speed) from my backpack before anything too bad happened.







  • Apple laptops are typically extremely good when it comes to sleep and suspend.

    A major advantage of having a very small range of hardware you have to support is that it’s pretty easy to test all possible combinations and make sure they work well together. As far as I’m concerned, Apple has been, and probably always will be the undisputed champion of doing this right.


  • I’ll say what I just said on a similar thread: if the internet goes down tomorrow, mesh will mean very little compared to ham radio.

    For what purpose? Hanging out with friends? Watching porn? Getting vital information around?

    AFAIK, ham is really mostly geared towards synchronous voice communication, whereas most of the Internet is asynchronous communication in a variety of forms: text, voice, video, etc. In an emergency, synchronous voice is pretty important. But, for day-to-day life, asynchronous dominates most people’s usage of things.

    So, if the Internet goes down tomorrow and you need to know why, what happened, etc. your best bet is probably not ham radio but normal TV and radio broadcasts, not rumours being spread by other random people using ham radio. If you live in a country where a complete overnight shut down of the internet, and complete stopping of all news broadcasts is possible, then ham might be useful for the first few days / hours to figure out what’s going on. But, in the longer term, ham isn’t really a replacement for the Internet. For that you’d want asynchronous sharing of various kinds of data, which is more a mesh network, not ham radio.



  • Yeah, good description. Fighting Entropy is really the trick that makes ONI great. I just love how at the beginning heat isn’t even on your radar as something to worry about. You might not even know that the heat overlay exists. But, by the mid-game if you don’t start handling heat suddenly everything starts breaking.

    Also, the size is another big difference. Factorio has that endless map where you just keep expanding your conveyor belts. The further out you go, the more you have to worry about aliens, but after a while that isn’t much of an issue. Meanwhile in ONI as you start making bigger and bigger colonies, it starts to feel cramped.





  • ONI has amazing “process engineering” where you take some substance, use a machine to transform it into another, feed it into a third, etc.

    But, what’s extra great about it is that it also includes a pretty basic, but still fully functional simulation of chemistry and physics. So, you can feed oil to the oil refinery to get petroleum, but it’s only 50% efficient. If you want a more efficient process you can boil the petroleum instead by dropping oil onto something hot. But doing that generates petroleum that’s at hundreds of degrees so you need to cool it down. So, instead of just doing that, you can pre-heat the oil coming into the boiler using the petroleum that the boiler produces, creating a counter-flow heat exchanger that cools the petroleum while pre-heating the oil.
