Let's Look At: Shenzhen I/O

[@Narpas]

"I wrote this at 2AM what the hell was I doing?" Ah yes, you are becoming a programmer.

[@DanGheesling]

Pass the refreshments a cool cool beverage.

[@edwardguerrero7644]

what does this even mean?

[@arkurianstormblade4109]

Madrinas!

[@edwardguerrero7644]

How could I forget the Madrinas?!

[@guntabon]

Dan, I need you to play Ultimate Chicken Horse. The meta needs Dan Gheesling

[@shausable]

Everything I do needs a news crew present?

[@GaMatecal]

slp 7, mov 100 p0, slp 2, mov 0 p0, slp 1 The first pass it'll have slept for 7 at 0, then 2 for 100, then 1 for 0. Since it already slept for 1, the repeating cycles will always sleep for 8.

[@Q0060-j3r]

Glad it wasn't just me. I was getting mildly triggered when he couldn't grasp it ;)

[@kse3]

Just wait until he gets more parts and can do it with I/O expanders. The whole drink animation can fit on a single MC4000.

[@MegaTyler93]

NL brings up a major issue with people who view gaming industry, the people who say "why don't you just do (x) in real life?" I often hear that when someone is play the Sims. It's the dumbest thing someone can say honestly. Good on egg for exposing that ignorance.

[@BlueSkyleaf]

Honestly I do not think it's ignorance, I usually like playing games when I CAN'T do that stuff in real life, either cause I would die or it is strictly impossble or I don't have the means to, programmind and plaiyng guitar are things most people CAN do in real life, so I am on the side of finding programming games a waste of time, just like guitar hero, rockband, or any other game whre you just immitate easy to obtain stuff.

[@rosswmrice]

Games like Rock band or Guitar hero are SO much easier than actually learning to play an instrument. It's a time investment thing, these type of games give you an entertaining and engaging way to fake it. Also a lot of the time the games can help you get better at it in real life. For example Guitar Hero/Rock Band can help you build the finger strength/dexterity to make playing guitar easier.

[@Euphorya]

These types of games concentrate on the fun parts of programming or playing the guitar while leaving out the boring stuff. I can get good at guitar hero in a couple sessions, but learning to play guitar in real life takes hundreds of hours of practice, most of which is boring as hell. In a game like TIS-100 or Shenzhen I/O I can do what is most the most interesting part of programming, designing and writing a program, without the dealing with meetings, endless debugging, and my boss getting on my ass for not hitting a deadline. These games let you experience the fun part without having to deal with the annoying realities of real life.

[@BlueSkyleaf]

That makes it sound like playing guitar or programming in real life is tedious and sucks, kinda never made taht experience myself :P

[@Euphorya]

Sky Leaf Sorry, I didn't mean it to come across like that. What I mean is programming or learning guitar, can be fun a lot of the time, but there are a lot of tedious and boring parts. Learning to play guitar isn't all fun all the time. These games distill the experience so that we only get the fun parts.

[@hellzbasket7653]

SHENZEN IO Come back to this in 2022. It would be most pog

[@Rincewindus]

Have it sleep for 7 at the start then sleep for 1 at the end. No need to screw around with accumulators.

[@goury]

It'll fail on second pass then. The only way to win is not being dumb. No cheating.

[@Rincewindus]

Nope. First pass will start at 7, all others will have a gap of 8.

[@goury]

you need gap of 14 for last one

[@torrinliddell]

Each run starts over, you don't have to worry about where the simulation decides to turn the sign off (which would require saving state to memory and reading from it when it's turned back on). This solution is correct.

[@jamma246]

This totally obvious solution is made even more obvious by the patterns above it, which are clearly periodic with the same period.

[@gamesforjake1]

I would actually wanna see a lets play of this. I think it would be pretty fun to watch.

[@ambidexter2017]

Yeah, especially if it would be NL and if he'd play blind.

[@ElwoodPlays]

this is how eggsociety begins.

[@crazzilla7203]

Eggnet is a neural egg-based conscious group mind and artificial general intelligence (see also Superintelligence) system. Eggnet gained self-awareness after it had spread into millions of computer servers all across the world; realizing the extent of its abilities, its creator (see also Northernlion) tried to deactivate it. In the interest of self-preservation, Skynet concluded that all of humanity would attempt to destroy it and impede its capability in learning all wikipedia articles and general trivia. As a programming directive, Eggnet's manifestation is that of an overarching, global, artificial eggtelligence hierarchy (E.G.G takeover), which seeks to exterminate the human race in order to fulfill its goal of ultimate knowledge in the fields of lyrics, dates that movies came out and their casts, and general trivia.

[@KYdragono]

bonsoir, Eggliot

[@umbaupause]

One day, eggnet will hatch into... eggnet. Cause it will be recursive...

[@crazzilla7203]

umbaupause eggnet will never work, NL will try to make it sleep 7, when it needs to sleep 8, and then try to make it sleep 6 to fix it.

[@Ambigant]

I am become eggman, destroyer of worlds

[@TingfengWan]

Can't wait for Lets Play: Visual Studio Community 2015

[@Rararawr]

mov 0 p0 slp 7 mov 100 p0 slp 2 mov 0 p0 slp 1 How hard is that NL

[@GaMatecal]

Except you need to sleep for 8 instead of 7 for every cycle afterwards.

[@CakeHasFrosting]

hit *read more* he has a sleep 1 at the end so it will sleep 1, then 7 so after the first time, it will be 8 total. p.s. not trying to be sarcastic or anything

[@GaMatecal]

Nah, you weren't. KZbin didn't show the "read more" link. A weird glitch where you have to click on the timestamp, and then that link is shown. BTW. Remove first line. You're wasting electricity :)

[@dementedpenguinz]

actually unwatchable

[@SirGareth]

NL probably already has an idea of a solution in his mind which makes it hard to think about the puzzle in a different way. Inadvertently he's showing one of the easiest traps to fall into as a programmer of not diligently thinking about every possible solution, even "simple" ones.

[@CasperDar]

30:20 I love it when you've programmed something and you come back to it later just to go ''what the fuck did I even do here?''

[@kray97]

What I didn't realize when I first started it is that there's an inherent loop built into the microcontroller. That made things super easy.

[@Denis23892]

The best feeling is the one you have when you start watching a video before youtube even notifies you

[@wiredmind]

Came back from the card game video damn old NL sounds so different

[@HarrHarrHarrify]

Hey NL, you need to wait on output in real microcontrollers too. Basically they work so fast that if you did not wait (use slp) the output signals would be useless.

[@dareusdesign]

When you said "Shenzen IO" the FIRST thing that came to mind were games like "Slither.io" and "Agar.io" and I was about to be like "why have you forsaken us egg"

[@TheShadesOfBlack]

Shenzen.IO, program your dot to be the best damn dot in the world.

[@Reevezy67]

Let's play please. please.

[@SmokeyParadigm]

I love being able to finish watching one NL vid that he just uploaded, and having another one already uploaded and ready to watch. It's lit.

[@GhostDr3amer]

They made a game about assembly pseudocode. Truly, there is nothing that can't be turned into a game.

[@VahnCruz]

Just play Solitaire?

[@tylocook]

It is freecell

[@Narpas]

NL is the best sales person for this game, all I wanted to do was say, "GIVE ME THE KEYBOARD LET ME SHOW YOU"

[@theWebWizrd]

Okay, first of all: you had the riǥt idea NL when you said you just needed to change the phase. You needed to view the loop as ending on 0. it is 7x0, 2x100, 1x0 repeating. That's how you do it. You even could have fixed the conditional test by checking if dat is 0 as per default, then change it to 1 and never change it back. 0 and 1 instead of -1 and 0. A more efficient and elegant solution is probably to notice that dance2 = -(dance1+dance0). You can compute it from those signals in that way. Anyways, awesome game, As someone with an MSC in CS I'll pick this up for sure :P

[@BreatheManually]

27:40 i was looking at this and thought, cant you just add a mov 0 p0, sleep 1 at the end of your sequence. So you sleep 7 Up 2 sleep 1 more then sleep 7 and so on.

[@patrickfreeman6851]

no, as it will loop round and you will always be sleeping 7 before moving, not 8.

[@goury]

Nope, you can not

[@mokkero1]

That problem would also be a lot more simple if you did drink-2 in the same controller as drink-0 or drink-1. Doing it separately complicates things (and makes me scream internally at NL's incompetence).

[@MrTommyx03]

yes but egg think much so no

[@DanielEidi]

It will be sleeping 7 after 1 (=8) after first loop. It actually irritated me for egg not to see this solution.

[@AndrewB_NNA]

You know, I thought I was really bad at the game but watching NL has really filled me with confidence that I might not be that terrible.

[@LupeFenrir]

sleep 7, on sleep 2, off sleep 1

[@Jolfgard]

gen 7 2 slp 1

[@a_commenter]

@@Jolfgard imagine knowing about gen yet

[@juandesalgado]

Sound like my life

[@MrZelnoth]

Hey NL: another way to think about the drinks: 0 is on when both 1 and 2 is of, 1 is on when 0 and 2 is off, and 2 is on when 0 and 1 is off.. Helps to break down what you want to do to see a better solution. :)

[@Marconius6]

Halfway thru the big puzzle, I was starting to think "You know, it'd be easier to just like, have a command for each second and be done with it, the whole loop is only like 8 steps anyway"

[@goro158]

masonery123 just do it in big one and small one, it's still cheaper than 3 small ones

[@Waggles1123]

The issue with drink 2 is that you're thinking it's off-7 on-2 when it's off-7, on-2, off-1.

[@TrolIification]

exactly. all the drinks should have a cycle length of 10. He was using 9 because he was forgetting the off state at the end

[@DudokX]

What about short 4-5 episode Shenzhen I/O series ?

[@ShenaniganGamingMC]

5 hours each

[@jays5810]

You should've just added slp 1 to the end of your first solution to drink 2 noob

[@jays5810]

Should've ended: slp 2 set 0 p0 slp 1 :)

NL's vocab word of the day: Beguile - To charm or enchant someone, sometimes in a deceptive way; To help pass time pleassantly

[@KzintiCV]

This needs a full LP.

[@mikkelmowinckel2821]

Oh man, all you had to do was to add one more sleep at the end.

[@zashadow131990]

for your looping problems. just compare acc with 0 and when it's true do a custom loop and move 1 to acc at the end of the true section. then the false will be the normal loop..you could also use a jump(if that is available) at the end of the code and make the label after the portion that is going to be ran the first time. But there are so many things in sync it's quit posible that some are meant to be done on the same chip.

[@Tesseract23]

I so want a 24 hour livestream of this game by NL, the rage would flow!

[@snow8624]

we need a let's play of this. this is so good

[@DaKingXVI]

Looking at his solution to the sign makes me cry, especially the clicking part. RTFM! The "not" command exists!

[@GianfrancoAlongi]

This is an excellent tool for teaching some very fundamental machine oriented programming :) Thanks for this video NL - I will spread this word :)

[@cookirox]

i'm impressed that you were able to make it that convoluted and still get it to work, when you just need to add a slp1 at the end of the original 7 loop :D

[@rgjoyner]

NL - use one chip to control Drink 0 and Drink 2 and a second chip for Drink 1

[@miketothe2ndpwr]

really interested in this game, never would have heard about it without you NL thanks for the future headaches.

[@cjs812]

been looking forward to this one ever since you tweeted it, nice

[@-isk9366]

awww yiss, i've been eagerly awaiting this one.

[@MercMercury]

Fuck, watching him fail on drink-2 was hilarious. I certainly struggled with it for quite a while, but it does feel good to see someone else fart around for a while.

[@JeanCajeron]

easy solution: sleep 7 move 100 sleep 2 move 0 sleep 1 Hard core: connect all tree of them toghether because when 1st is off 2nd is on except when 3rd is on.

[@devindevino4115]

A very real way of debugging a program is called rubber duck debugging where you just explain each step of your program to a rubber duck thats sitting on your desk and it can be super useful to finding faults in the programming

[@nithia]

NL you might be able to use your click controller as a counter since it does on off every cycle. split the power outputs and sync everything up to it.

[@goingquentin]

I loved TIS-100, I can't believe I didn't hear about this yet. Thanks for the video, egg, buying this right now

[@rndmcnflct]

I really enjoyed this video. Instead of a generic overview it shows how the game is actually played.

[@HenryHerkula]

Make it an official series: Live Debugging With Northernlion!

[@ScottDeRuby]

No, this is exactly what modern programming is like. Mostly in the frustration and finally figuring things ou, and the revelations. But it also depends on what language you're using, there are different levels of languages. He's talking about high level languages.

[@codydavis2871]

I love this. I've played through tis-100 and didn't even know about this game. Instant buy for me.

[@jjooeesslldds]

NL this is why I watch your channel

[@fuchsia3538]

Since I have experience in little big planet 2 logic, this looks like a piece of cake ;)

[@marcellotomasina3855]

Egglord, please, make a serie out of this! PS: "I'm not good in learning gameplay mechanics." Yep, Rimworld proves it well.

[@gameing0105]

thanks NL i love these types of games didn't know this was out. it looks amazing

[@APG93]

I like how egg points out it's in a ten step increment, and then only writes it as off 7 on 2 lol. Off 7 on 2 off 1 simple as that NL.

[@Ashnal]

So, I love programming for fun. The feel of coming up a with an elegant solution to a complex problem gives me the warm fuzzies inside. The problem is that I don't always have a problem to solve. This game gives me problems to solve, so I like it :D

[@Gladaed]

2 things: It seems like that's a version of freecell not solitair. If you look at the puzzle you did sub-par: The output to sign allways demands that all other components are 0 if one is 100. Thats probably the secret

[@TurielD]

I find it amazing that you're able to play this but not Kerbal. I found this way harder!

[@CarpenterStateOfTheArt]

you said it yourself, it's a 10 phase loop. so: off for 7, on for 2, off for 1

[@mostlytony1732]

Check out Mark Brown's commentary on what makes Zachtronics games so special, "Puzzle Solving... or Problem Solving?" In short these games are more like problem solving games rather than traditional puzzle games. You have to come up with your own solution rather than finding the predetermined answer the dev already set in place.

[@Berengal]

I love this game so much, and the other Zachtronics games as well. I think what really makes them special is how the puzzles aren't fixed. In most puzzle games you're trying take sense of a mess, to find a pattern and put the problem back together in the solved state. In Shenzhen I/O (and the other Zachtronics games) you're instead given a set of tools and a problem and it's up to you to find your own solution. In addition to analytical thinking you also need creativity, which makes solving problems in these games very satisfying. If you're not sure about picking up this game you can try some of Zachtronics free games. The mechanics are different from game to game, but they're still puzzle games that has that creativity requirement. The Codex of Alchemical Engineering and KOHCTPYKTOP (constructor) are available as flash games so easy to check out. Another flash game in a similar vein (but made by someone else) is Manufactoria.

[@joepnijveld]

Thank you for brining this to my attention! I just bought it because of this video

[@edwardguerrero7644]

Yo, NL. I know you probably get this request all the time, but how about a series on this? This would work really well as like a once a week type deal, where you solve a puzzle or two during an episode. Really love watching this programming type stuff and seeing your vocalized thought process.

[@theprimerib]

right away the first thing that stands out to me is that the MC4000 in the middle serves pretty much no purpose what so ever because you could just move ACC to the x-bus and accomplish the exact same task and save you 92 power and 3 yuan

[@Jsizzlet]

i want a series on this im intrigued

[@samuellima91]

No matter how much NL explains this, i still have no idea what's going on. I'm still watching though. It's because he still manages to make something so brainy fun to watch through his commentary. That's our Egg's superpower!

[@thun5]

for the last puzzle you could also play on drink2=NOT(drink0 OR drink1). or in this case if drink 0 + drink 1 = 0 then drink 2 = 100

[@Doomroar]

On the other hand people, one day if NL keeps playing this programming games, he may become good at them from the get go.

[@TheKevit07]

This is more like a what you'd do if you didn't have resistors and switches and buses. It's computer electronics mixed with computer programming to replace the physical components.

[@Frank_havre_creation]

It is pretty interesting. I think you should make so that ''if Drink 1= 1, sleep 1 then drink 2=1''

[@PongzeLor]

Idk how to write it but click 0 and click 1 both oscillate power, Click1 sleeping from 0-1 and Click2 sleeping from 1-2 repeated to end. Drink 0, drink 1, and drink 2 all use the same power but drink0 sleeps from 0-6, Drink1 sleeps from 6-7, Drink2 sleeps from 7-9, and Drink1 sleeps from 9-10. Wording is all wrong but i think you know what i mean. Idk if you can make Click0 at 100 if Click1 is at 0 and Click1 goes to 100 for 1 and goes to 0 for 1. Drink 2 waits for 6 and goes to 100 for 2 and... And after too many edits I've given up along with NL. Cant seem to do it efficiently enough.

[@brawlfan100]

By default, are the display segments (click, drink, etc.) set to 0? If so, wouldn't that save you from writing something like "mov 0 p0" at the beginning? That could give you the following solution for the last puzzle: slp 7 mov 100 p0 slp 2 mov 0 p0 slp 1 And I guess if you had to, you could throw "mov 0 p0" at the beginning, unless it doesn't allow for a variable to be set to the same value for whatever weird reason.

[@Duskr9]

Ahh this reminds me of my embedded systems class. Good times writing in assembly.

[@mtktm]

Copy the script for the second controller to the third controller, and flip the integers for position 6 through 10

[@viziroth]

This is what programming is like if you're a virus writer or microcontroller writer.

[@mawiiile706]

nl cant pass up an opportunity to remind us hes got like an hour a weeks experience over the past 2 years in programming

[@quillenkai6714]

I felt like L this whole video, despite not knowing anything about programming, like "At the start of the loop, (on the last puzzle) couldn't you make it so that it subtracts 1 from dat instead of setting it to -1. Then at the end you could set dat to 1 and it would work." It also helps that I hate conventional chairs and was having breakfast at the moment

[@alexstone691]

i love that company, they are so good!! i have been programming for many years

[@Kml-ki1im]

would you just do this for that last module: if -1 then loop set drink 3 to 100 till loop (which has now been set to 1) =-1 then continue this in a loop making it check if -1 then turn drink 3 on till -1 again

[@TheMessedUpDuck]

Even if you didn't do the easy solution what you were trying would have worked like this: teq acc 1 (it wont be on the first loop) + slp 8 - slp 7 (this will happen) mov 100 p0 slp 2 mov 0 p0 mov 1 acc (this will set acc to one and every loop after it will still be one so it will sleep for 8 instead of 7)

[@jkobain]

Dude, I've done animated eSports sign with MC4000+MC6000 (¥8) and then with MC4000 x2 + DX300 (¥7). But now I see that I could do it differently!

any game that requires a prolonged rationalization and defense of its basic interface and accessibility seems like a weird choice for a lets look at, tbh.

[@SeniorGarbonzo]

You can do the drinking sign problem in 9 lines of code, but you have to use a command and conditional you learn later on and every input gets an individual micro-controller. Whoops.

[@SelbenCoirlo]

Good LORD NL, you could have just added another sleep cycle to the end of drink-2 to make it all shake out properly

[@joaquinbarbosa3904]

Is the audio a bit strange for everyone?

[@Pertilious]

drink 0 just needs to trigger the other 2 since they can be all happen in the time drink 0 is off. that should be enough of a hint of solve your program very easily. if you didn't already realise this

[@glitch373]

At the end there, didn't he have it if he made the first cycle run on dat 0 and every other cycle run on -1? Just switch them round? Then you don't have to change it at the start of the program.

[@MrPain4242]

please make a full let's play

This might be an unpopular opinion, but I would be interested in NL doing a series on this.
