Not sure proprietary cores are welcome here :) but I wanted to post to say that this question/challenge was one of my inspirations in developing the MCL86 core. I was exited to see that I was not alone in my affinity for the Intel 8086/8088 as it was the processor in my first computer, the IBM PC...
once again I kindly ask your opinion on the meta posted I just edited based on the feedback received, about the dreadful topic of how to start sed and spot the newline.
Yes
Edit: I received feedback about the method of calling sed, shown below, as being misleading because of what sed actually receives as input. I will try to explain better.
sed -f script_file <<< ""
The syntax command <<< "" is an input redirection of an empty string and is equivalent to run...

@MartinEnder it's an adaptation of an approach used by tails in a different language, and i wanted to keep it separate from my other completely different solution
it's not extremely common to submit that way (usually people submit your_username (their_username) when it's in the same language), but anyway i didn't notice another user who used that approach besides tails, it seems tricky to come up with and i certainly didn't see it before the deadline

@Downgoat do you know where I can find information on the structure of programming languege compilers/interpreters? I've searched online but couldn't find anything.
@DerpfacePython I'll take a look. It seems to be written for interactive use (so I'd have to strip the prompt for the file name), but more importantly, I have to figure out if the two calls to eval are safe.
@MartinEnder I don't know. Not really. A V answer (which I actually just posted) would have the exact same approach, but just happen to use a much more efficient encoding. I guess one reason I went with vim is because recently I've been feeling like V is kinda cheap. Like, it takes an already golfy language and just adds a whole bunch of stuff on top without necessarily being more interesting.
It seems to me that this isn't really compatible with the requirement that every answer should "be a serious contender for the winning criteria in use". — Peter Taylor3 mins ago

The task is to convert a string to a number. It must accept the string via stdin and output the number via stdout.
You much convert a string to a number by replacing each letter of the string by its index (mind that you don't need to replace it with the index, that's just an example. You a...
@MitchSchwartz I just brute forced Duplicate Characters. there are 8 different 6-byte solutions (plus 3 equivalent ones), but most of them are so messed up there is no chance I'd ever have found them. two of them are fairly reasonable though, so if you want a challenge...
based on the no input rule regarding sed and how my way of calling sed was interpreted, I had to delete a meta post and rephrase about 5 answers. Sorry for artificially cluttering the active questions page.
Long time ago, when I was spending more time playing RPG, one of the issues what some players had, was to track party movement and to draw proper map.
So I come with idea, to check how you guys come deal with this issue.

@MartinEnder thanks for the info :) i could just look at your submission if i wanted, since it's a post mortem problem, but i'll spend a bit of time trying to solve it on my own, as i was planning to do with echo
actually i already thought about trying to beat 6 in echo before you submitted your 5, but didn't have any workable approach
oh, interesting. i was thinking along the lines that your 6 was guaranteed to exit without errors, and it could be possible to beat it by terminating with an error
@DJMcMayhem The point is that you're not alone. :P
What's actually kinda funny to me is that it's something I've seen people realize multiple times, perhaps because they never saw someone else realize the same thing. :P
Relatedly, anyone else ever have those moments where you suddenly notice something you've seen for a while?
Sorry to everybody who participated in StockExchange. I found two critical bugs that dramatically changed the scores
(the first was that I wasn't properly removing stock from the seller, the second was that I was giving the loser a score of 1 and the winner a score of 0)
@MartinEnder i caught up on ascii x01 to xf7 with different stats (one binary character instead of two) and one no-op, and i have an 11-byte not-solution that goes to \x80
