Q: Riddle me this!

Cameron VinesI flew on a lark, sang on a trill, crashed on a wing. What am I? I've tried to figure out this riddle posed in a comic book. There was no official answer, but it is visually suggested that it is comprised of only 2 letters (The context was a crossword death-trap, and the word in question was mar...

Q: A Tale of Snake and Coffee

pirateI had the strangest dream last night: I am in field of red stones. I start walking around until a smell of fresh coffee catches my attention. I follow it until I see a large cave, and in its entrance there's a snake. The snake speaks to me: "I will let you enter only if you can tell m...

Q: A series of blocks (total $n + m$) is given to us and 0 is stored initially in each.We are given a number $H$ and we can choose $H$ blocks at a time

ShrijanaOperation - we can choose $H$ blocks at a time and can fill those blocks with digit 1. we can do this Operation as many times we want. if block has already 1 in it and we are going to put 1 again then as a result 0 will get stored in it. We want to fill as many 1's in first n blocks and as much ...

 
@GarethMcCaughan Nice job on my puzzle. Did the hint give it away, or was that one of the ideas you'd already had percolating?
 
The hint didn't give me anything new. The most informative thing was your comment to whoever it was that ASCII isn't involved. I'd been looking for solutions involving changing or permuting small numbers of bits. It happens that if you include a parity bit (as used by e.g. the Model 33) the numbers of 1-bits in GOTR and (s)MOKE match up, as do those in ESU and (w)ILL.
I hadn't, though, considered using the keyboard layout, because I am a moron.
 
hehe
 
So once you made it clear that ASCII wasn't relevant, the fact that being a Model-33 teletype was relevant (and I didn't think it likely e.g. that you'd got your facts wrong and were basing the puzzle around Baudot code or anything like that) gave a pretty big clue as to where to look.
 
I wanted a teletype so there was a record of prior passwords, and the 33 was the earliest with a fairly traditional keyboard layout

@Sphinx This same user posted on stack overflow stackoverflow.com/questions/56566498/…
 
I'd bet heavily that it's from some sort of competition, but I haven't yet found what competition.
oh, wait, no, that one I recognize, but it's not the same as the one here.
The one s/he posted on Stack Overflow was posted here at least twice.
 
Someone else posted the same thing on puzzling but I think they self deleted
 
(and definitely comes from the current CodeChef contest)
 
Yeah there seems to be at least one other competition going on, which we think we've had two questions from so far
 
Unfortunately that last one seems difficult to search for -- the original might have been about an array of numbers, or bits in an integer, or empty/full boxes, or all sorts of other things.
 
12:15 PM
Yeah, I've not had any luck finding it
 
It might've been that they've tried to mask the original problem but in doing so they asked something completely different or they have created their own problem after making progress in the competition

Q: Maximize sum of a Bipartition

SteveWe have a sequence of numbers say X. The goal is to divide this sequence into 2 parts such that the sum of the Greatest Common Divisor(G.C.D) of both the sub-sequences is maximum. Note : The G.C.D of a sequence is the G.C.D of every element of the sequence. E.g. G.C.D of (4,4,8) is 4

@GarethMcCaughan I think your C4 is ROSINANTE (nag): (dom)INANT (overbearing with lowly Indian abondoned) in ROSE (love with the first letter moved to the back or "head over heels")
 
Yes! Well done.
(I thought it was rather a tough one.)
 
Yes, definitely not a write-in.
 
I came across that word when I was trying to solve this, but couldn't make the wordplay work. Congratulations.
 
I like how you jump through hoops to get the rather plain ROSE.

Q: Distinct SemiPrimes with Close Factors

Wolf LarsonI'm in the midst of developing a game for several friends as a friendly competition.
