+=====a deeper dive on paths (absolute vs. relative)=====
-the / means "from the base of the system"

-KalebJ12Yesterday at 4:28 PM
-Okay
+wedge: no leading '/' needed here; the '/' means "from the base of the system"
-wedgeYesterday at 4:28 PM
-var is at the base of the system, so we prefix / to var
+K: okay
-when we are doing short hops like this (known as a relative path), we just specify the name
-your prompt should change (pct1 should append to the end)

-KalebJ12Yesterday at 4:30 PM
+H: What was the path called with /, I know it starts with an 'a'
-Woah so if I ls I see everyones account and the files
-wedgeYesterday at 4:30 PM
+wedge: an "absolute" path
-absolute paths start with /, relative paths do not
-yep
+H: Ah yes
-any files of particular interest?
-KalebJ12Yesterday at 4:30 PM
+wedge: an "absolute" path is like your street address. A universal address for a place (123 fourth street, city, state, zip).
-Manifest
-HannahH02Yesterday at 4:30 PM
+wedge: whereas a "relative" path refers to your current position (the bathroom? Down the hall, 2nd door on the left).
-I’m only half way through the mage book and there is so much info in it lol
-wedgeYesterday at 4:31 PM
+wedge: an "absolute" path works from ANYWHERE on the system. A "relative" path only works from a certain location.
-:slight_smile: hey, you're already well on your way
-considering the semester hasn't even started yet
+wedge: a common clue is that absolute paths will start with '/', whereas relative paths do not.
-EVERYONE will need to go through what you are experiencing now... making those essential connections
-you stand to have a much easier time, because we have so much time
+K: Woah so if I ls I see everyones account and the files
-KalebJ12Yesterday at 4:32 PM
-So say I wanted to be in the same place i am rn on my pi is that possible?
+wedge: yep
-wedgeYesterday at 4:32 PM
-that directory would have to exist on your pi (it does not)
+wedge: any files of particular interest?
-HannahH02Yesterday at 4:32 PM
-Now I see puzzle, this is making a lot more sense
+H: I’m only half way through the mage book and there is so much info in it
-wedgeYesterday at 4:32 PM
-(but don't worry, when we're done you should have your puzzle on your pi)
+wedge: hey, you're already well on your way

+wedge: EVERYONE will need to go through what you are experiencing now... making those essential connections
-wedgeYesterday at 4:33 PM
-sometimes it just takes a question to be asked :slight_smile:
+wedge: you stand to have a much easier time, because we have so much time (a week out from the due date)
-yep
-KalebJ12Yesterday at 4:33 PM
+K: So say I wanted to be in the same place I am right now on my pi; is that possible?
-Got it
-wedgeYesterday at 4:33 PM
+wedge: that directory (and the contents that drew you to it) would have to exist on your pi (by default, it does not)
-also: have you all set up your repository on lab46 (and your pi)?
-KalebJ12Yesterday at 4:33 PM
+wedge: but don't worry, when we're done you should have //your// puzzle on //your// pi
-Yes
-I did that today
+H: Now I see puzzle, this is making a lot more sense
-I submitted ntr0 and I was going to help Hannah on her ntr0
-HannahH02Yesterday at 4:34 PM
+wedge: sometimes it just takes a question to be asked
-I haven’t done it on my pi yet but I just put it together so I will later today
-wedgeYesterday at 4:34 PM
+K: I only see "MANIFEST"
-I only ask so as to better calibrate my answer...
-okay, so yes to lab46 at least on both?
+H: You’ll need to go into the directory named as your username
-KalebJ12Yesterday at 4:34 PM
-Yes
+wedge: yep
-HannahH02Yesterday at 4:34 PM
-Yes
+K: Got it
-wedgeYesterday at 4:34 PM
-good. ok
+wedge: so you wander into your respective "username" directory. What is there?
-so you wander into your respective "username" directory. What is there?
-KalebJ12Yesterday at 4:35 PM
+K: a file called "puzzle"
-On my pi?
-wedgeYesterday at 4:35 PM
+H: when I run "ls" from within the "username" directory (under pct1), it outputs "puzzle"
-on lab46
-where we are now
+wedge: yes, you should see a single (gray/white) file called 'puzzle'
-KalebJ12Yesterday at 4:35 PM
-Puzzle
+wedge: files that are coloured gray/white are "regular" files... which includes things like text files
-HannahH02Yesterday at 4:35 PM
-Under ls is puzzle
+wedge: how could we view this file, assuming it was a text file? (there are MANY ways)
-wedgeYesterday at 4:35 PM
-yes, you should see a single (gray/white) file called 'puzzle'
+wedge: and you both have mentioned things that could be made to accomplish this task
-files that are coloured gray/white are "regular" files... which includes things like text files
-how could we view this file, assuming it was a text file? (there are MANY ways)
+H: Do we use the more and less commands with this one?
-HannahH02Yesterday at 4:37 PM
-Do we use the more and less commands with this one?
+wedge: yes- "less" or "more" can do the job
-wedgeYesterday at 4:37 PM
-and you both have mentioned possibilities
+wedge: and so can a text editor, such as "nano"
-yes: less or more can do the job
-so can nano
+wedge: but, I'll give you one simpler
-but
-I'll give you one simpler
+wedge: the command known as "cat"
-the command known as: cat
-KalebJ12Yesterday at 4:37 PM
+wedge: cat filename
-I like nano
-wedgeYesterday at 4:37 PM
+wedge: "cat" is like a straight up file viewer; it displays the contents to your screen and returns to the prompt (unlike nano or more/less, cat is NON-INTERACTIVE, meaning it just does its thing, without any further interaction from the user)
-cat filename
-can is like a straight up file viewer
+wedge: if you cat your 'puzzle' file, you should see the puzzle. Yes?
-displays the contents to your screen and returns to the prompt (unlike nano or more/less, cat is NON-INTERACTIVE, meaning it just does its thing, without any further interaction from the user)
-if you cat your 'puzzle' file , you should see the puzzle. Yes?
+H: Yes, so should we work on paper then just add it on nano?
-HannahH02Yesterday at 4:39 PM
-Yes, so should we work on paper then just add it on nano?
+wedge: yes, although, we're not quite done yet (going to add it to your repository)
-wedgeYesterday at 4:40 PM
-yes
+K: Mine seems like its solved
-KalebJ12Yesterday at 4:40 PM
-Mine seems like its solved
+wedge: @K it isn't solved, you need to figure out the numeric identity of the letters
-wedgeYesterday at 4:40 PM
-BUT: I'll do one better
+K: OHHHH okay
-I'll now show you how to copy that puzzle file INTO your repository, into a pct1 directory of your own.
-@KalebJ12 it isn't solved, you need to figure out the numeric identity of the letters
+=====Adding your puzzle into your lab46 repository=====
-KalebJ12Yesterday at 4:41 PM
-OHHHH okay
+wedge: I'll now show you how to copy that puzzle file INTO your repository, into a pct1 directory of your own.
-wedgeYesterday at 4:41 PM
-ok: getting our puzzle into our repository
+wedge: now, for this next step, you will need to have set up your repository on lab46:
-KalebJ12Yesterday at 4:41 PM
-So do we make the directory on the pi with mkdir
+K: Yes, did that today
-wedgeYesterday at 4:42 PM
-it might be a good idea to set up a structure, so all are class data is organized
+H: I have done it on lab46
-@KalebJ12 nope, we're going to make mercurial do it
-KalebJ12Yesterday at 4:42 PM
+wedge: good. ok
-Okay
-wedgeYesterday at 4:42 PM
+wedge: ok, getting our puzzle into our repository
-but we ARE going to run mkdir on lab46:

+wedge: @K nope, we're going to make mercurial do it
+K: okay
+wedge: but we ARE going to run mkdir on lab46:
+wedge: run the following (from where-ever you currently are, on lab46):
+<cli>
 mkdir -p ~/src/unix/pct1
-^ type that
+</cli>
-can you then tell me, WHERE is that?
-KalebJ12Yesterday at 4:43 PM
+wedge: can you then tell me, WHERE is that?
-We should go back to lab46: ~$ first right?
-Or does it not matter
+wedge: I mentioned the '~' symbol before. It means something to the computer, a shortcut we can use
-wedgeYesterday at 4:43 PM
-nope
+wedge: what is it?
-doesn't matter
-but ONLY because I am giving it an absolute path
+H: Nothing seemed to happen for me
-I mentioned ~ before
-what is it?
+wedge: correct, mkdir did what was requested of it
-HannahH02Yesterday at 4:44 PM
-Nothing happened for me
+K: It made it but we arent in it so now we go into it
-wedgeYesterday at 4:44 PM
-correct: mkdir did what was requested of it
+wedge: if you just get your prompt back, you were successful
-KalebJ12Yesterday at 4:44 PM
-It made it but we arent in it so now we go into it
+wedge: UNIX is "user friendly" like that... it doesn't go and say "SUCCESS! YOU DID THE THING. ARE YOU SURE?"
-wedgeYesterday at 4:44 PM

+wedge: it assumes you know what you are doing
-UNIX is "user friendly" like that... it doesn't go and say "SUCCESS! YOU DID THE THING. ARE YOU SURE?"

+K: We have to copy the puzzle file to the new directory we just made
-KalebJ12Yesterday at 4:45 PM

-wedgeYesterday at 4:45 PM
-we just made a new directory, INSIDE our home directory (~), under src (created when you set up your repo on lab46)

-actually created a "unix" subdirectory, and inside that, "pct1"
-we can now copy our puzzle file here, INTO that ~/src/unix/pct1 directory

+K: cp file name
-Cp?
-Ah
+H: cp?
-wedgeYesterday at 4:46 PM
-cp source destination
+wedge: more generically, cp "source" "destination"
-here we are in the public directory... pct1... puzzle is here

-Dang
+wedge: and the destination?

+K: dang
-careful- src is not at the base of the filesystem... it is in our home directory (~)
-HannahH02Yesterday at 4:48 PM
+K: cp pct1  /src/unix/pct1
-How do we get the puzzle in there though, do we use the name puzzle?
-wedgeYesterday at 4:48 PM

-yes: puzzle is the source
-~/src/unix/pct1 is the destination
+K: I was so close dang
-again: you should get your prompt back if you did it correctly
-yes?

-KalebJ12Yesterday at 4:49 PM
-Yes
+wedge: "~/src/unix/pct1" is the destination (where we want to put that copy)

+wedge: yes?
-Yes
-HannahH02Yesterday at 4:50 PM
+H: Got it
-Yes
-wedgeYesterday at 4:50 PM
+wedge: ok. an 'ls' should confirm our file is there
-but now: anything under ~/src/ is trackable by mercurial, in our repository
-so, go and ADD puzzle to your repository (that hg thing)
+H: Yes
-hg add puzzle
-it may say "added puzzle" or some such thing
+K: Yup
-yes?
-KalebJ12Yesterday at 4:52 PM
+wedge: a 'cat' should confirm that the contents are still there
-Mine didnt say anything but I did it again and said that its already there
-wedgeYesterday at 4:52 PM
+K: yes
-ok, good
-KalebJ12Yesterday at 4:52 PM
+H: yes
-So it worked
-wedgeYesterday at 4:52 PM
+wedge: and now, as anything under ~/src/ is trackable by mercurial, in our repository
-actually: hg status
-it should also show 'puzzle', with a green capital A to the left of it

-KalebJ12Yesterday at 4:53 PM
-A unix/pct/puzzle
+<cli>
-wedgeYesterday at 4:53 PM
+lab46:~/src/unix/pct1$ hg add puzzle
-hg status shows us the state of the current snapshot
+</cli>
-yes
-HannahH02Yesterday at 4:53 PM
+K: So it worked?
-Sweet got it
-wedgeYesterday at 4:53 PM
+wedge: actually, run "hg status"
-okay, now COMMIT it:
-hg commit -m "adding my pct1 puzzle"
+wedge: it should also show 'puzzle', with a green capital A to the left of it
-HannahH02Yesterday at 4:54 PM
-What does commiting it do?
+K: A unix/pct/puzzle
-wedgeYesterday at 4:54 PM
-takes a snapshot
+wedge: "hg status" shows us the state of the current snapshot
-KalebJ12Yesterday at 4:54 PM
-Like a log? Of what's happening
+wedge: yes, that's it
-wedgeYesterday at 4:54 PM
-the current state of all the files listed in 'hg status'
+H: Sweet got it
-like it saves the current instance of the file
-but yes, in log-like fashion
+wedge: okay, now to COMMIT it (aka take a snapshot of it):
-KalebJ12Yesterday at 4:55 PM
-So should we hg push?
+<cli>
-wedgeYesterday at 4:55 PM
+lab46:~/src/unix/pct1$ hg commit -m "adding my pct1 puzzle"
-yes
-push sends the snapshot to the server
+H: What does committing it do?
-which for the purposes of getting it on the pi, definitely something we want
-so do that.
+wedge: takes a snapshot
-at this point, @HannahH02 , since you haven't set it up on your pi yet, will be something to check out later
-but basically: once you have added, committed, and pushed it
+K: Like a log? Of what's happening
-HannahH02Yesterday at 4:56 PM
-In the future do we work more on the pi or lab 46?
+wedge: the current state of all the files listed in 'hg status'
-wedgeYesterday at 4:57 PM
-you can switch over to your pi, go into your ~/src directory on your pi
+wedge: like it saves the current instance of the file
-(the intent is, yes, that you do the bulk of the work on the pi)
-mainly getting files from and putting finished files to submit back on lab46
+wedge: like a sort? Sort of. There is a log.
-@KalebJ12 in your ~/src on your pi?
-KalebJ12Yesterday at 4:57 PM
+K: So should we hg push?
-Yed
-Yes
+wedge: yes, after you've committed, you want to push the snapshot to the server. "hg push" does that.
-wedgeYesterday at 4:57 PM
-hg pull
+wedge: which for the purposes of getting it on the pi, definitely something we want
-then: hg update
-then, do an 'ls'
+wedge: so do that.
-KalebJ12Yesterday at 4:58 PM
-Unix shows up
+=====Retrieving your puzzle on your pi=====
-wedgeYesterday at 4:58 PM

-run 'ls'
-KalebJ12Yesterday at 4:58 PM

-now, to get things from your pi back to lab46-- add/commit/push on the pi
+K: in your ~/src on your pi?
-then on lab46: pull, update
-back and forth, whichever way you need at the moment
+wedge: Yes
-KalebJ12Yesterday at 4:59 PM
-Yeah I had to do that with ntr0
+wedge: now, run "hg pull"
-wedgeYesterday at 5:02 PM
-so there you go: I hope that helped clarify things somewhat :slight_smile:
+wedge: followed by, "hg update"
-HannahH02Yesterday at 5:02 PM
-Thank you for all your help!
+wedge: as a bonus, if you'd like to see the log, you can now do "hg log" (if it doesn't let you out, 'q' to get out)
-wedgeYesterday at 5:02 PM
-no problem! Thank you for asking questions
+wedge: then, when back at a prompt, do an "ls"
-KalebJ12Yesterday at 5:03 PM
-So 9 = K is the highest number?
+K: a directory called "unix" shows up, that wasn't there before!
-wedgeYesterday at 5:04 PM
-maybe
+wedge: go in there, and run "ls"
-um... you don't have a K
-KalebJ12Yesterday at 5:05 PM
+K: directories! "ntr0" and "pct1"
-I was looking at the chart on the lab46 website
-wedgeYesterday at 5:06 PM
+wedge: go into the "pct1" directory, and run "ls"
-oh, the puzzle I walk through on the project page?
-KalebJ12Yesterday at 5:06 PM
+K: Hey, my "puzzle" file is there
-Yes
-Do we ever go above the letter k?
+wedge: there you go
-wedgeYesterday at 5:06 PM
-yes, in that puzzle, K is 9
+=====The reverse, sending from pi to lab46=====
-Yes: when we work on a puzzle in a base higher than 10
-KalebJ12Yesterday at 5:07 PM
+wedge: now, to get things from your pi back to lab46-- do any add/commit/push commands on the pi
-Oh no lol
-wedgeYesterday at 5:07 PM
+wedge: then, back on lab46 (in ~/src), do your pull, update in hg (in that order: pull, followed by update)
-for the foreseeable future, we'll be working in base 10
-but we will dabble in other bases... 8, 9, 11
+wedge: back and forth, whichever way you need at the moment
-in 8, there is no 9 (or 8!)... we go from 0-7
-but, nothing to fret about at present... just focus on base 10 :slight_smile:
+K: Yeah I had to do that with ntr0
-KalebJ12Yesterday at 5:08 PM
-Okay
+wedge: so there you go: I hope that helped clarify things somewhat
-wedgeYesterday at 5:11 PM
-by the way: the point of pctX is to get you to strengthen your abilities to describe a process (and think critically)... since we'll eventually be writing shell scripts, it helps if you've got some experience tending to details from start to finish of a particular task
+H: Thank you for all your help!
-because if you cannot specifically describe from start to finish a process you are personally doing by hand, you're going to have a heck of a time instructing the computer to do something.
-plus, they're super fun, and you'll eventually want to do them all the time!
+wedge: no problem! Thank you for asking questions
-KalebJ12Yesterday at 5:16 PM
-So with the puzzle if we submit the wrong answers do we get points off lol
-wedgeYesterday at 5:16 PM
-yes
-KalebJ12Yesterday at 7:46 PM
-On the pct1 our answer do we submit it as numbers or letters?
-wedgeYesterday at 8:08 PM
-You submit the letters in order from least to greatest
-There is an example on the projects page
-KalebJ12Yesterday at 8:10 PM
-No for the verify part where it shows the example of there being a remainder
-wedgeYesterday at 8:11 PM
-Oh, you don’t have the remainder. So you do a different verification (there is also an example on the project page)
-wedgeYesterday at 8:22 PM
-Basically switching out to numbers, solving, then switching back to letters to see if they match.
-The example is probably more helpful in showing what I mean
