    They could weaponize their propulsion system pretty trivially. Even if it just means "point empty ship at city and accelerate to a significant fraction of the speed of light".

    A modern hospital or the geeks at a LAN party have tons of modern technology at their disposal, but neither could defeat a Roman legion.

    This is a deceptive analogy. You are right, they couldn't beat a roman legion if the roman legion showed up unexpectedly at the front door. But the society that produces these things can weaponize it trivially... just via the side effects and by-products of peaceful technology. We'd have to know about things like nitroglycerine, hydrochloric acid, chlorine gas, bacteria, molds, nerve toxins, anthrax, gasoline gel (napalm), etc, etc. We'd have all kinds of advanced knowledge about toxins and how they affect us, just from our manufacturing experience.

    As a society, we'd just take all of the above, and load it into those planes used to fight forest fires, and dump it on them. And in some cases, maybe follow it with a lit match (flare gun).

    Anybody willing to make such a database? :-D

    We're talking stupidly big numbers, not your garden variety big numbers. To paraphrase the Hitchhiker's Guide to the Galaxy:
    "Its big. Really big. You just won't believe how vastly hugely mindbogglingly big it is. I mean you may think it's a long way down the road to the chemist, but that's just peanuts to these."

    Using very rough numbers, at around 500 digits, around 99.9% of integers are composite, meaning around 0.1% are prime. (I'll leave proof of this as an exercise to the reader.) For the sake of the discussion, lets assume that is an accurate 'prime density' for the range of 500 digit numbers.

    So, to create a database of the 500 digit prime numbers we'll need to store 0.1% of them. So far so good.

    So how many are there. Lets look at 3 digit numbers (100-999) inclusive; which equals 999-100+1 or equivalently 10^3-10^2.Or we can express it even more conveniently as (10*(10^2))-(1*(10^2) = 9*(10^2). And the general formula for how many n digit integers there are is 9*(10^(n-1)). For 500 digit numbers there are 9*(10^499).

    Ah, but we only need 0.1% because we are only storing primes, so we multiply by 0.001 or 10^-3 and get:
    9*(10^496).

    Our database is going to need around 9*(10^496) records for this...

    If it hasn't already made itself clear to you, this poses a serious problem. There are estimated to be around 10^50 atoms on earth. So even if you could store an entire database record on an atom, and the entire planet was used in our storage system, we'd still run out of atoms before we made a measurable dent in the data set we need to store.

    In fact, if we used every atom in the universe we'd still run out of atoms before we made a dent in the data set. The universe is estimated to have fewer than 10^81 atoms.

    We couldn't store this data set even if we had a billion billion universes worth of atoms.

    And that's just the 500 digit primes. We haven't talked about 501 digit primes yet...

    If a known algorithm produces the encrypted password, why can't that algorithm be "reversed" to produce the original password in the first place?

    It has been. But it doesn't really do you any good. The actual password is lost. The reverse of a hash produces infinite solutions. (In the same way the reverse of modulus division produces infinite solutions).

    But those solutions are all 'collisions' and they could all be used interchangeably with the original password. So getting any solution is almost as good as getting the original.

    Even in open source systems, encrypted passwords are not easy to crack. Why?

    Because pretty much all modern encryption is based on the idea that its VERY easy to multiply two stupidly large prime numbers to find an even stupidly larger number. Multiple two 1000 bit prime number numbers and get a 2000 bit non-prime as a result.

    But it takes years upon years of processor time to take that stupidly larger number, and factor it back into the original stupidly large primes.

    Could a slashdotter post some "simple to understand code" that produces output I cannot reverse engineer?

    z = primex * primey;

    suppose z = 377, how do you find the factors: 13 and 29?
    Now, for encryption, z is thousands of digits instead of 3.

    If you really want to remove it, you simply need to remove it from the add-ons folder manually, with suitable priviledge escalation.

    - Hackers discover a way to exploit this.

Then I release D, and don't know whether to release A, so now A needs to have some sort of reference counting mechanism, and I have to remember to use it each time I create or copy or pass a reference to A.

    Or... I can use a language that implements the reference counting stuff for me and implicitly calls it when I allocate new objects, create, copy, or pass references, and expire them as they go out of scope, without me having to write explicit destructors.

    Basically, if you do any sort of remotely complicated object allocation where you are going to need to implement reference counting to keep track of them, you might as well use a garbage collector. That's what it does, it comes thoroughly debugged, and you don't have to waste time implementing and debugging your own.
