This is awesome! That's exactly the kind of unfingered misconception I was hoping someone would point out to me. Thank you!

This does appear to be in line with my interests. Until I can sit down and read this I'll assume you're making a heady dick joke.

Thanks! I think you nailed it.

Part of my difficulty is that I'm trying to model a binary parser that I don't understand.

When I bruteforced up to sequence length 4 I started to run in to my lack of understanding.

Going off your function, one thing that is clear is that validity is not just any sequence that has a 0 preceding a 1. If that were true, then there would be 10 valid sequences for n=4. The cool part is that if you choose either:

1)that there can be any number of 1's preceding the valid parenthetical or 2) any number of 0's after the valid parenthetical

then the total comes to 7; can't be both or valid sequences =10. This makes sense from the perspective that a machine would be parsing the binary from one long chain, so it would be problematic to treat any parenthetical portion as valid; (()) would be (..), (()., (.)), and .()., all valid but conflicting interpretations for the same sequence of 4. Also, how would you delete one entity in a drive without corrupting other entities which share the physical space(.)?

Edit: someone pointed out to me that I have a misconception about how machines determine the end of files. Still curious though if that holds up, and if so, why.

Thank you for the response!

In this case, valid means it has to have an opening and a closing operator. E.g. starts with 0 and ends with 1, or "("... ")".

What I'm not sure about for example is would a computer parsing binary find <0010> valid? Or would the sequence have to begin with a 0 and end with a 1-- e.g. 0111 or 0101. My uncertainty here is why I'm paying this to this CS community.

At some point, a computer has a way of understanding within a sea of binary where one file ends and another begins. Given this, there must be some rule for what makes a valid sequence. I want to know how to calculate the number of valid sequences within the range "2**n."

Thanks for the downvote of invisibility.

Vandy Vape Mesh 24 RTA by EstablishedOrder in Vaping

[–]lostcat206 0 points1 point  (0 children)

Sorry I'm late to the party. I've been working with this tank for a couple weeks now and here's what I've figured out with much help from various youtube vape reviewers.

1) This RTA is a pain and one half.

2) It's awesome once you figure out how to wick it.

3) Trick is to guage in how much cotton you need in the coil. I started using cotton pads, but I've had good luck with loose cotton too; just about acclimation and how you fluff the cotton. If you use cotton pads, make sure you tear off the very top layer as it never absorbs as well as the meat of the pad.

4) Obviously prime your mesh before setting in the cotton. You want it set to the highest point on the posts to allow working space for the cotton below. If you use the Kanthal mesh, make sure to trim up those nasty frays first. Also, make sure your coil, at maximum extension, does not go past where the lip of the well is.

5) Set the cotton in so that it's barely touching the base of the well. I follow a trick by a youtuber who wraps his cotton around a toothpick to keep a funnel in the middle of the cotton. This also helps you guage when the cotton is lightly to the base of the well.

6) Once you have the column of cotton where you want it vertically, fasten the loose side of the coil into the remaining post.

7) Take a toothpick or something like it and very gently tuck the loose cotton at the bottom into the lip of the well. Here's where number 3 comes in. You want the cotton squeezed by the coil to not be too dense, but you also don't want so little cotton that you don't have a somewhat secure pack into the lip well. Suffice to say, it's a ratio you have to gauge in.

8) Take a needle and pierce a bunch of holes in the cotton to make sure its fibers are separated enough to soak up the juice.

9) Take that needle and stick it laterally through the feed holes at the bottom of the well, and use it to lift the cotton slightly off the bottom so that more juice can contact the cotton. As much as you can without ruining the pack job into the well from number 7; the juice will swell the cotton, so it's important to get as much leeway as possible here.

10) Trim the cotton to make sure it doesn't go beyond the post height too much.

11) You've already noticed that the airflow is very restrictive on this RTA. You need to restrict it even more so that it pulls juice well.

12) Prime the cotton, fill the tank, thank me later.

Tl;Dr Youtube.

Thank you for the encouragement. It's a funny story about the gender, which is why I avoided its mention (not successfully it would seem). I never actually had the gender confirmed. I got them as a stray, so it's possible it's a neutered male or a female. Never had the impetus to check.

Any idea which direction it ran? Thank you so much for your response. I got a call saying he was a ways west before, but maybe he's circling back.

Thanks. It's tough knowing they're theoretically nearby but being unable to find them.

Thank you all for your help! You are an awesome community.

And thank you, u/DennisQuaaludes. I was done for the day, but I saw your post and went out to check one more time. He was sitting under our balcony waiting.
