    sounds something like call of cthulhu rules.

    If you successfully use a skill during play, without the help of Luck points, mark the box next to it. Between scenarios, you get to roll to improve any skills you marked. To improve the skill, roll 1d100. If you roll higher than your skill, it improves by 1d10. After you’ve rolled for all the marked skills, erase the marks.

    personally i think xp is too fiddly. i prefer systems like fate where you can just rewrite skills to fit your style of play better.



  • learning to use a workshop has nothing to do with how the tools are constructed. open source means very little to people who are not familiar with software tools, and is not likely to get someone started.

    as soon as you are even starting on an intermediate level you need to care a lot, because you start building your own tools. but before that point, open source just means the big players. good luck explaining the benefits of awk before they know the difference between office and openoffice.











  • you’re calculating the sha256 (i think) hash of the previous transaction block’s hash plus your block of transactions. What’s making it proof-of-work though, is the stipulation that “the hash has to start with at least five zeroes”, with “five” being an adjustable difficulty value. To be able to get that specific hash an otherwise meaningless number (a “nonce”) is included, and by increasing this number by one you can change the hash value.

    so basically, all these servers are running hash calculations on the same thing over and over again with a single number changing between runs until they get an “approved” hash value. whoever gets there the fastest gets their block added to the chain, then everyone else has to start over with that hash as the “previous” one.

    It’s called “proof of work” because it’s difficult to find a suitable value, but it’s trivial to check that it’s correct. you just need the nonce. so by presenting that nonce to everyone, you’ve proved that you “did the work”.

    as for the reason why they do this, if each block’s hash is dependent on the hash of the block before it, it means the entire chain is resistant to tampering. you can’t insert a block in the middle without recalculating the entire chain.
