03:51:41  <substack>jjjjohnnny: indeed!
03:51:49  <jjjjohnnny>LETS PLAY GUESS THE IDEA
03:51:51  <substack>jjjjohnnny: I want a block-smashing sniper rifle
03:51:59  <dominictarr>what about a programming tutorial that is just opening the console and messing with sites via js
03:52:14  <dominictarr>WEB CHEATCODES
03:53:02  <jjjjohnnny>cheated
03:53:07  <dominictarr>like in twitter you have jquery and you can do stuff like
03:53:16  <dominictarr>$('.favorite').click()
03:53:29  <dominictarr>and instantly favorite everyone
03:53:58  <dominictarr>I did that yesterday, and like 15 new people followed me
03:54:04  <jjjjohnnny>dominictarr: i don't know if we should teach js the same way we learned it :\
03:54:21  <jjjjohnnny>that is jquery first
03:54:40  <dominictarr>well, not all sites have jquery
03:54:51  <dominictarr>like facebook doesn't
03:55:06  <dominictarr>the point is, to show kids where the controls are
03:55:16  <dominictarr>show them what power they have
03:55:42  <jjjjohnnny>its a good idea tho i like it #swish
03:56:42  <jjjjohnnny>dominictarr: i tried to get my NKO team to do an a similar idea for the command line
03:56:52  <dominictarr>how so?
03:57:01  <jjjjohnnny>basically adding a layer of fine customization on top
03:57:08  <jjjjohnnny>curate specific functionality
03:57:42  <dominictarr>not sure what you mean. can you elaborate?
03:58:02  <jjjjohnnny>well, adding simple UI to the CLI
03:58:09  <jjjjohnnny>addomh search
03:58:12  <jjjjohnnny>adding
03:58:33  <jjjjohnnny>by command line, i mean a CLI built in HTML5
03:58:43  <jjjjohnnny>which runs your programs CLI style
03:58:59  <dominictarr>right. the web dev console? or the terminal?
03:59:08  <jjjjohnnny>terminal
03:59:44  <jjjjohnnny>you know, use play, rec, youtubedl, and myriad node programs
03:59:50  <jjjjohnnny>tuner
04:00:15  <jjjjohnnny>but for people who dont use the CLI at all yet
04:01:00  <jjjjohnnny>instead of having an icon somewheres, they can type "timer 20 dingdong,mp3
04:02:17  <dominictarr>right… so is it just a terminal in the browser?
04:02:29  <dominictarr>or is there additional handholding involved?
04:02:35  <jjjjohnnny>plus some small amount of style and UI
04:02:54  <defunctzombie>dominictarr: has to be simpler than that
04:02:54  <jjjjohnnny>helpers
04:03:00  <defunctzombie>really the basics start with simple variables
04:03:05  <defunctzombie>and changing them to see results
04:03:23  <dominictarr>defunctzombie: yes seeing results is what i'm going for
04:03:38  <defunctzombie>the problem is even with teh jquery example you are bringing in a lot of notions that would not be obvious
04:03:45  <defunctzombie>like what is this ".favorite"
04:03:49  <defunctzombie>why is it in quotes
04:03:54  <defunctzombie>what is special about the $
04:04:00  <defunctzombie>why is the .click not in quotes
04:04:07  <defunctzombie>why are there two () after click
04:04:12  <dominictarr>yes, but you need to motivate first
04:04:30  <defunctzombie>when you start to break down a simple statement like that it is very complex in reality
04:05:04  <defunctzombie>software is complex because it is abstract
04:05:10  <defunctzombie>you gotta make it less abstract
04:05:14  <dominictarr>when you just start at "hey, so this is a variable, isn't that cool! numbers!" that is not exciting unless you can do something with it
04:05:22  <defunctzombie>this is why simple block based approaches work really well
04:05:25  <defunctzombie>and the lego stuff is great
04:05:30  <dominictarr>but people are familiar with cheatcodes
04:05:38  <dominictarr>as an arbitary pattern
04:05:42  <defunctzombie>that is a terrible way to start (the variable thing)
04:06:20  <dominictarr>but the difference with these cheat codes is that there is a logic to them.
04:07:02  <dominictarr>anyway… this is just another approach to try.
04:07:07  <defunctzombie>yep
04:07:08  <dominictarr>not the be-all-end-all
04:07:29  <defunctzombie>the problem with the cheat codes is that it isn't easy to think about it yourself outside the scope of what you were told to copy and paste
04:08:13  <dominictarr>that is when you direct users to a regular tutorial
04:09:01  <dominictarr>explaining something is one thing, but the most important thing is to get people to realize that programming is fun.
04:10:02  <dominictarr>if you have that, they can just teach them selves.
04:11:36  * gwenbelljoined

04:17:43  <gwenbell>ok, i can send it to you if you want
04:18:05  <gwenbell>dw?
04:18:12  <dominictarr>yeah
04:18:25  <gwenbell>it feels so long ago now

04:21:05  <dominictarr>scheming ways to teach programming
04:21:27  <dominictarr>(read: promote anarchism)
04:21:55  <gwenbell>i took some classes at codecademy, and i love eloquent javascript! what have you come up with?
04:22:20  <dominictarr>just an idea,
04:22:42  <dominictarr>a tutorial based on opening the dev console
04:22:56  <dominictarr>and poking about websites with javascript
04:23:17  <dominictarr>like, on twitter you can do $('.favorite').click()
04:23:32  <dominictarr>and favorite EVERY tweet that is on your timeline.
04:23:38  <gwenbell>nice
04:23:47  <gwenbell>for all time?
04:23:50  <dominictarr>I did that yesterday, and got 15 new followers
04:24:09  <gwenbell>b/c it pings them when they're favorited?
04:24:09  <dominictarr>no just the ones they are on the current page
04:24:14  <dominictarr>yes

04:29:56  <dominictarr>no, I clicked every favorite button manually. with love.
04:30:33  <dominictarr>(yes, I used jquery, but still with love)
04:38:46  <gwenbell>dominictarr: sent!
04:38:55  <dominictarr>thanks
04:41:21  <mbalho>gwenbell: http://for-cats.com
04:41:35  <dominictarr>gwenbell: I think one of the problems with social media is that it's not just like regular life (which can get pretty hectic on it's own) but it's actually designed to addict you and change your behaviour.
04:41:45  <gwenbell>right
04:42:02  <gwenbell>that's why i quit all but github
04:42:14  <dominictarr>sometimes I wonder if you could design systems that people wanted to use, but didn't drain you emotionally
04:42:15  <gwenbell>which, now that it has a leaderboard thing going on is taking on an addictive quality all its own
04:42:37  <gwenbell>which may not be problematic if it makes us not just more prolific coders, but more thoughtful ones, too
04:43:09  <dominictarr>hmm, I'm not sure
04:43:40  <gwenbell>i just don't go to the web for nutrition other than to learn/find new info -- i don't go to the web as much for emotional connection anymore
04:44:08  <dominictarr>sure
04:44:44  <dominictarr>but for somethings, it would be impossible to build a community around without the internet
04:45:21  <dominictarr>because there is not sufficient density of people with that interest, except in a few places
04:45:42  <gwenbell>mbalho: amazing
04:49:31  <gwenbell>dominictarr: my guess is when we have a truly p2p connection with people, the addictive components will start to abate

21:53:22  * gwenbelljoined
21:53:24  * gwenbell_joined
22:26:15  <Raynos>mbalho: it is hard.
22:26:35  <mbalho>Raynos: what part? i admittedly have a naieve understanding
22:26:38  <Raynos>because your effectively doing time travel
22:27:01  <Raynos>the part where your client runs about n ticks behind the server
22:27:53  <Raynos>but when you shoot locally your actually sending a message to the server saying "I shoot gun at tick n" and server is at tick n + latency and it needs to go and merge that state change in the past and replay things
22:28:31  <Raynos>the main point is the server can't say event happened at SERVER_TIME because that sucks for gameplay for clients
22:28:45  <Raynos>and each client has it's own local clock and the server needs to play events in the past to match the clients clock
22:28:49  <Raynos>and shit is fucked up ._.
22:28:55  <Raynos>time travel. <rageface>
22:28:57  <mbalho>lol
22:29:02  <mbalho>well ill give it a shot and see how it goes
22:29:11  <Raynos>it doesnt matter for non real-time stuff
22:29:22  <Raynos>for bullet trajectories it's kind of important :p
22:29:44  <Raynos>don't create any short lived really fast entities like bullets :D
22:30:23  <Raynos>mbalho: there's another problem. Consider a pushable box in 3D and 4 players. Each player pushes the box at their own clock. Considering the emulation of the box's physic runs on the server, what's the correct state of the box at any time?
22:30:24  * Dspriggsjoined
22:30:37  <Raynos>note that correct is not about what's correct
22:30:43  <mbalho>well im just turning on and off voxels
22:31:01  <Raynos>it's about from a client's gameplay point of view what is interpreted as fair
22:31:06  <mbalho>gotcha
22:31:18  <Raynos>anyway.
22:31:19  <CoverSlide>TIL game development is hard
22:31:26  <Raynos>none of these edge cases are probably relevant
22:31:40  <Raynos>which is awesome because those edge cases suck
22:32:14  <mbalho>lol
22:32:35  <Raynos>mbalho: what's really interesting is thinking about how you can build a distributed server that allows each client to run it's own local emulation of game state and not have an authorative server
22:32:52  <Raynos>central authorative servers running the simulation of the game are boring
22:33:25  <mbalho>Raynos: what does a decentralized case offer in terms of game mechanics (and not just a new engineering problem to solve)
22:34:20  <mbalho>Raynos: or is it just about not having to pay for a server
22:34:29  <Raynos>well you make latency dissappear
22:34:34  <Raynos>because your doing all your emulations locally
22:34:41  <Raynos>there is still latency from other players
22:34:46  <Raynos>but there is no round trip to server latency
22:34:59  <Raynos>the other game mechanic you gain is offline play
22:34:59  <mbalho>Raynos: interesting, is there any game that has ever done that?
22:35:47  <mbalho>Raynos: i think seamline offline/online or at least syncing from a offline 'instance' to an online server somewhere would be compelling
22:36:06  <Raynos>mbalho: I can't think of any games like this, me and jden were talking about what it looks like to build a game where p2p is a feature
22:36:18  <mbalho>Raynos: but i think you can achieve offine and sync without abandoning synchronous server
22:36:31  <Raynos>mbalho: think of multiple universe game. Want new features / content / experience. Connect to a random peer and merge his parallel world into yours
22:36:57  * defunctzombie_zzchanged nick to defunctzombie
22:37:18  <mbalho>Raynos: sure, as long as the perceived latency 'feels' the same
22:37:50  <Raynos>the other thing about a p2p system
22:37:58  <Raynos>is the feature of being able to become a server
22:38:00  <Raynos>and host a game
22:38:02  <mbalho>Raynos: im gonna implement a centralized server first just to do it and get familiar but then this sounds interesting to hack on
22:38:07  <Raynos>but that's negated by just making it very easy to build a server
22:38:12  <mbalho>Raynos: yea
22:38:41  <Raynos>But dont listen to me
22:38:43  <Raynos>I have a p2p fetish
22:50:45  <chrisdickinson>i would think that the p2p clients would randomly "elect" a server
22:51:03  <chrisdickinson>and that to keep things fair-ish you could reelect every N turns

23:10:12  * j_dulaneyremember y'all were here
23:10:36  <Raynos>chrisdickinson: I would think about partitioning the world into n partition and each client has control of a section
23:10:46  <Raynos>so only one client runs the emulation for a world partition at a time
23:11:00  <chrisdickinson>(aside from prediction)
23:11:03  <Raynos>which would work nicely with parallel worlds
23:11:17  <Raynos>because each client emulates it's own world.

23:15:29  <mbalho>chrisdickinson: whats the scope?

23:16:27  <mbalho>chrisdickinson: all of our collision code is here https://github.com/maxogden/voxel-engine/blob/master/lib/game.js#L425 which calls this https://github.com/maxogden/voxel-engine/blob/master/lib/player-controls.js#L86
23:16:47  <Raynos>mbalho: it sounds fun.
23:17:40  <mbalho>chrisdickinson: ours is arguably easier because its a voxel world so we dont have to do raycasting, just penetration vectors (which we havent implemented really)

23:19:39  <chrisdickinson>i suppose voxels help more with "what could i hit", not "what do i do when i've hit it"

23:21:11  <mbalho>tanepiper: https://github.com/maxogden/voxel-engine dont tweet yet
23:21:15  <chrisdickinson>so my original approach was going to be "give me an object with position, and computed current velocity, and a list of those objects" and it would transform the original object's velocity appropriately

23:25:00  <Raynos>chrisdickinson:
23:25:04  <Raynos>> Matt: Collision detection is trivial in voxel land
23:25:04  <Raynos>Really trivial
23:25:04  <Raynos>You have a fixed grid
23:25:04  <Raynos>You stepwise move any moving objects by a distance proportional to the grid size
23:25:04  <Raynos>And block test
23:25:38  <chrisdickinson>theoretically
23:25:59  <chrisdickinson>but really you want to do the penetration test because that's what you (for example) slide against a wall that you're running slightly into
23:26:07  <mbalho>thats what we do now but getting the velocity and collisions and crap to feel correctly is tricky
23:26:10  <mbalho>chrisdickinson: yes that
23:26:31  <mbalho>chrisdickinson: any ideas on how to implement sliding against a wall with our current collision setup linked above?

23:29:13  <jjjjohnnny>vectors plus vectors
23:29:17  <chrisdickinson>yeahhh
23:29:27  <chrisdickinson>so you're doing after the velocity has already been applied

23:30:37  <chrisdickinson>tbh i usually have to write and rewrite and rewrite collision code
23:30:59  <mbalho>chrisdickinson: it seems hard to generalize
23:31:22  <chrisdickinson>i feel like it could be generalized, especially with aabb-plane collisions
23:31:39  <chrisdickinson>and then you just need a "view" onto the voxel data that makes the voxels "look like" planes.
23:32:04  <mbalho>chrisdickinson: you can look up a x,y,z coord and you get if it is in a voxel or not
23:32:12  <mbalho>chrisdickinson: O(n)
23:32:24  <chrisdickinson>shouldn't it be O(1)?

23:45:22  <chrisdickinson>so you subtract the new point from the target plane's origin to get the origin_to_new_point vector, get the vector from the origin of the plane to the top right of the plane, dot those two vectors together...
23:46:20  <chrisdickinson>if it's < 0 or > cube plane size, there's no collision and it can safely be skipped
