    Is it alright to go around wiping the OS off of other people’s computers?

    • is what your comment reads like to me.

    To be clear: each machine generally needs a computer to be permanently plugged into it. Generally the computer belongs to the university. You’re not plugging in your own personal laptop into the machine. Saying to install Linux on these computers is essentially tampering with the university’s electronics and IT will be very unhappy that you did that.

    That’s the thing - in space, orbits don’t decay. Orbital decay only happens if there’s dust or atmosphere that you bump into along your orbit to slow you down. But in interplanetary space, there’s no dust or atmosphere, and certainly not enough to decay your orbit fast enough to achieve results (otherwise, the Earth would have already decayed and melted in the Sun)

    You need to spend fuel to lower your orbit to hit the Sun, and you need to spend fuel to raise your orbit to escape the solar system. It turns out to be really freaking difficult to hit the sun because it simply requires so much fuel to lower your orbit enough to hit the Sun.








  • You can’t outright, but you can at least try to minimize your exposure. Easiest way is to avoid buying products that use plastic packaging, especially if the product that you’re planning to buy is food. Don’t microwave plastics, even the supposedly “food safe” one - that releases a ton of microplastics into your food. Don’t order takeout - again, lots of plastic in the containers. Even paper food containers contain a plastic coating.

    Don’t touch receipts, especially with wet hands. Or at minimum, wash your hands thoroughly after touching it

    Scientists can get really petty in peer review. They won’t be able to catch if the data was manipulated or faked, but they’ll be able to catch everything else. Things such as inconclusive or unconvincing data, wrongful assumptions, missing data that would complement and further prove the conclusion, or even trivial things such as a sentence being unclear.

    It generally works as long as you can trust that the author isn’t dishonest






  • Flying is definitely the first challenge that players tend to meet. Just use autopilot. You can cancel the autopilot mid-flight, and you absolutely should cancel the autopilot if you start to see that a planet is getting in your way. Most people just fly with the autopilot, and that’s really my biggest advice.

    If you really insist on flying manual, don’t treat it like driving a car. Spaceships (both real and in-game) drift most of the time. You want to get up to speed (400 m/s is a good top speed most of the time) and then drift the rest of the way to your destination. Do you see the white dotted arrows coming out from the planet that you’re targeting? You want to get those arrows to be as short as possible. If the arrows are visible, that means you’re not lined up with the planet and you’ll miss the planet



  • Yeah, people tend to have that problem, especially if they’re treating it like driving a car. If you want to fly manual, never fly more than 400 m/s, because then you won’t have enough time to slow down.

    My actual advice though is to just use autopilot. People seem to forget that you can cancel autopilot. If you start to see that there’s something getting in your way, cancel the autopilot and push the ship to the left or right (it’s easier to go around the planet than to slow down). Once you’re clear, resume autopilot.



  • Yes, and people do do it. It’s just incredibly difficult to do it even for relatively simple programs, and the more complex the program is, the more exponentially hard the reverse engineering will be.

    The problem is not necessarily turning it into code, since many decompilers do it already for you nowadays. The issue is understanding what in the world the code is supposed to do. Normally, open source code would be commented and there would be documentation, so it’s easy to edit or build on the code. Decompiled code comes with no documentation or comments, and all the variable names are virtually illegible.

    It’s sometimes easier to build something new than to fix what’s broken, and this would be one of those cases where it’s true
