I never quite realised how insane good auld Bob actually is. He'd make a great super-villain. And he edits video like someone who just found out iMovie exists... And I love him
I've never believed that such simple and obvious talks are really needed, until I had the opportunity to work for a company where this was the way they wrote code, with an extreme avoidance of almost any abstraction... So it really is good that we have such videos explaining the very basics of good programming practices.
What an awesome teacher! I'm still waiting for the second video of "Programming 101 with "Uncle Bob" ". I wanna see more and learn more from you. Please Uncle Bob, continue with this 101 videos. Thanks.
I agree with your statements about loving programming. I have been retired for 7 years and still program my computer nearly every day. Curiously, I remember, when I first started programming back in the late '60s, wondering if it was a good thing to get into as I thought it wouldn't be long before all the programs that were needed would be completed.
Thank you so much uncle Bob. This is what I've been missing all my life. As someone who didn't study computer science, this has been really helpful. I'm going to spend the next few weeks consuming all related content.
Beautiful how he gets the message across that in the first place the program should implement what the user really needs, not what you think he needs nor what the user thinks he needs.
I'm a profesional programmer I have been coding for years now but uncle Bob always teaches something even on basic videos. Thanks I'm a big fan of you :)
Had to stop here 30 minutes in and say 'Thank You !!' . Great stuff , as someone going back to school at 38 years old and having had little hands on experience with programming before , this is just the pace I needed to really help me solidify my understanding of basics. 8 years ago, I completed a college course as a personal elective in Computer Logic and Programming and while I was offered much there none of it really stuck as I didn't continue my studies and only took that and a basic Microsoft Office course and wasn't super interested. .... I greatly appreciate the playfulness in your style of teaching here in this video , just very personal feel and entertaining pace ... I've watched another hour long talk you gave to a group of programmers on clean code - over my head , but I really enjoyed it too. Anyway big thanks !! This video = ( BIG VALUE , LEGACY, JUST GOOD FUN )
This is a brilliant presentation, I learned more here than I did while attending college. Look at a problem closely, understand it. Since your first solution is probably clunky, go back simplify the solution. The example is excellent, simple and illustrated the information perfectly. Thank you, Bob.
For absolute beginners (something for my daughter), but still I love to watch him. By the way, I have just checked: "finger" in Latin is "digitus" exactly.
For beginners, but there's gold here for more experienced programmers that might never have stopped to think about the simple things, or just take them for granted. I had never thought about the && table being the inverse of ||, or vice versa, for example.
Is it just me, or was his programming if his first chart opposite of the chart? If the A, B switches were the same, the light should be off. His first code for A, B stated if A and B were the same state the light would be on.
This definitely makes me appreciate electricians a lot more. They have to lay out these complex logic circuit with just wires and switches. Talk about your bare-metal programming :)
@39:00 what about counting the Ts? even yields F, odd yields T (parity bit, 1-bit checksum), right? @45:00 beside doing the XOR with an array of switch values, this XOR implementation is fascinating and lot more efficient (works with only one bit) and cannot get into number overflow exception, compared to counting and doing mod2... quite like SAX compared to DOM, for processing XML: the latter could run out of memory, right? @45:17 the truth tables: yeah but... you mentioned it's 16 of them, I'd say it's 16 "basic-functions", but did you show them all? Can't recall... I've been hoping to hear from you about the "implies" function, or the role of the "nand" function, especially in electronics. And by the way, if those "2-inputs-basic-functions" are 16, what about the 4 "1-input-basic-functions"? You showed only the "not" one... @1:00:50 good, but... it's not the best representation, which should be an array of bits... using integer that way, or strings, to "create a human-visible array of bits" it's a waste of money... also: we're past mid of the 101, but when are loop to be shown? to me, now is the right time to show what an array of bits (booleans) actually is, now that the watchers have "seen one", and how to work on arrays with loops @1:18:36 yep, Parmenide's "being and being-not" indeed... and number theory in maths starts with 0 and 1 too, but with + and *, not with the 4-unary and 16-binary functions (not to mention the "doubt function", which starts it all: otherwise is nihilism or faith). You'd definitively enjoy the "Shannon machines", i.e. "how many bits you have and what you do with that"... it's TDD, it's bottom-up, it's fun stuff.
That DEC PiDP-8 12-bit Octal Computer Hobby Emulator / Simulator casually blinking yellow LED lights in the background is the ultimate CS Flex though....
I saw Pascal in the opening screen and ... well, it was a really good language for its time - I remember when the UCSD Pascal came out on the Apple ][. I did a lot with it. Back to watching ...
it's because he's using arduino IDE and is in the loop method, he has the opening brace off screen so as not to confuse/overcomplicate for the more intro crowd
Such a great video, I was rapt from beginning to end. I think Java was a bad choice though. In python there isn't the distraction of obtuse symbols not is not, and is and, or is or. You wouldn't even need a method. Anyway, great stuff. You give a good name to bonkers. :)
In his data table he wrote that up&&up or Down&&down was light off. But what he put in the code was the opposite, with the light on. The dual lightswitch still works, but it was not coded as planned.
The house I owned and lived in 1996-2000, the 3-way light switches had separate top and bottom push buttons, and did not display their state (Cinturon by Leviton). The house had four pairs of such switches. Every encounter with one of these switches was a crap shoot. The "You never have to hunt for the state of the switch" was totally screwed/scrapped.
The only thing I would add at the end of this is to get the audience to think about if you had more switches you wouldn't want to change the code each time a new switch comes along.
Hello, very nice video, would love to keep seeing them. Just a note, i couldn't find the source code in the site, is it only available if you buy the video? Thanks in advance
class FourSwitchScenario implements SwitchScenario { Error message: The nested type FourSwitchScenario cannot hide an enclosing type Using Processing 3.5.4. I'm lost trying to get things working in the code not shown.
I am looking for the rest of this series , but I cannot find anything. I would be willing to buy them if I could find them. I don't have a lot of experience programming but I am interested in learning more about it, and I like the way you approach the subject.
So I like these simple explanations, but I am personally missing one point for the switches, which for me is important to understand. If the switches do not have effect on each other, then the light always goes ON when switch A is switched to the UP position and the light always goes OFF, when switch A is switched to the DOWN position. For switch B, the opposite is true. So in that example it is crucial to understand that the actual switching (in real life: physically switching the switch) determines a change in state of the light. The reason I am saying this is because this behavior is what someone might expect only seeing the switches without the wiring. For instance in that scenario: if switch A is switched UP, the light would go ON. Now if switch B is in the UP position and we switch it to the DOWN position, the light turns ON, as we disregard the effect of switch A. As the light was already ON though, we don’t notice the change. So, maybe that explanation would be interesting to add too and afterwards show the part with the wiring, where the logic of the switches interact. To show the program for the independent behavior, you would then say: if the state of a switch changes (goes from UP to DOWN or vice-versa) we either turn the light ON or OFF, depending on how the switch works. This way the logic of both switches completely ignore the logic of the other switch, but they both control the light. So, we have two completely separate inputs that control the same output. Me saying this might sound very silly and straightforward if your brain works very well, but I wanted to say it nonetheless.
Man, if I had the money I'd pay Uncle Bob to be like a Bill Nye the Science guy but for programming. Young kids could benefit so much from him if he had his own show on Netflix or Hulu or something.
You wrote the table at 16:00 and then you went and programmed directly opposite logic in the program. In the real life and in your table on the paper when both switches are up or down, the light is off, but in your program when both switches are up or down, the light is on!
both in same position = equals (==) in opposite positions = not equals (!=), which is logically the same as: either one is up (true&false or false&true) = exclusive or (xor)
My theory as to why ! is called "bang" is that on the old teletype consoles (like those used to control early computers), the ! symbol was the shifted value of the "B" key.
What about dividing a problem into modular blocks where you have them move in a loop like a chain. Then the process runs with different sets of data with different inputs to verify that one block of data has moved and changed relative to block data b to make a complete transaction say a change of currency? Where A and B are changed by moving x amount from A to B and verify that said trans action has taken place by a compatitor that makes sure that each has changed by the same amount where A loosed x and B gains X amount and that the change of X is the same but inverse relative to each other.

16:35 - XOR light switches 20:04 - XNOR code 36:16 - okay, order is restored, he's coding xor
Can anyone point me to any living code or even dead code that he has written? I checked his wiki entry and it has no mention of anything other than writing about how others should code and proselytising his own ideas. What has he actually worked on? What has he done? Where is his code? Does he have a repo I can go and poke through?
The users intent will be relative to the last 'stable' state of the light. (stable meaning the last state which persisted for >500mS). An odd number of flips, intends to reverse the last stable state of the light. An even number of flips, intends to restore the last stable state of the light. I wish such consideration for timing went into web browsers. If I click on something 15mS after a page completely re-arranges itself, it's probably not what I wanted.
This is a free lecture on clean coders and I want to get the extas as described, but they don't seem to show anywhere on the site. Can you dd them here or lt me know how to get into them somewhere else?
Having about 35 years of programming experience I haveto say: Well done - Uncle Bob. I really like that he is showing that even such a simple thing like light switches may take a lot of thinking to be solved "perfect". And he is also right in my opinion - if somebody has no fun in programming it will be hard till impossible for him to get a real programmer. But I think he is wrong in his assumption that the number of needed programmers will increase exponentialy in the next decades. One reason why I think that will not happen is that code is getting more and more platform and operation system independend - while in the past the same application has to be implemented for several plattforms this is now often no longer necessary or at least much easier as in the past The other reason is that in our days nearly every algorithm for specific problems is already written and easy to find in the Internet - so often programming is now more and more searching for already existing "parts" which when "only" have to be connected to each other. And even when the improvements in Software development are ridicoulos slow compared to the improvements in the hardware modern development tools are getting better and also programming languages have definetly improved other the years (just compare the first version of Java with the actual one)
My self-made function generator doesn't have software in it: it is all dumb hardware. But the software is in the PC that manages it. It was an attempt of mine to escape software, but it didn't work. Anyway, this guy is a genius!
Wonderfull, in the past I saw programmers'oath, very short videos, but now I didn t find anywhere, maybe have been deleted, but I don t know why, was very interesting videos :(
I will be honest, had You been my teacher in Highschool - I would have grown to love Programming. Instead my teacher just nagged us all the time and gave us super advanced codes that she didn't explain anything about.
i just brought the third edition of algorithms by thomas H cormen, and idk why im here but can anyone recommend any great books for data structures and algorithms. recipes for coding

Is it just me, or does it seem like there are an awful lot of relatively experienced programmers, like myself, on a video titled Programming 101?
its because we strive to improve and see if we "looked over" something.
for the same reason that even top sportsmen, like Tiger Woods, still need coaches
it´s because I like to listen to Uncle Bob regardless to my 35 years professional software developer experirence
learning is fun to us

You are correct, he would just have to swap the words On and Off in the code to match the chart.
@@nathanwittland8112 I just started to scratch my head when he did that opposite to the chart, but overall good concepts to learn from!

Great video!
You wrote the table at 16:00 and then you went and programmed directly opposite logic in the program. In the real life and in your table on the paper when both switches are up or down, the light is off, but in your program when both switches are up or down, the light is on!
On the note card it was captured that both up or both down should make the light OFF, not ON. Then he programmed it the other way.
I thought I was the only one noticing that... hahaha
That's at least 3 of us.
both in same position = equals (==)
in opposite positions = not equals (!=), which is logically the same as: either one is up (true&false or false&true) = exclusive or (xor)
Great video. Thanks for sharing.
My theory as to why ! is called "bang" is that on the old teletype consoles (like those used to control early computers), the ! symbol was the shifted value of the "B" key.

I really like that he is showing that even such a simple thing like light switches may take a lot of thinking to be solved "perfect".
And he is also right in my opinion - if somebody has no fun in programming it will be hard till impossible for him to get a real programmer.
But I think he is wrong in his assumption that the number of needed programmers will increase exponentialy in the next decades.
One reason why I think that will not happen is that code is getting more and more platform and operation system independend - while in the past the same application has to be implemented for several plattforms this is now often no longer necessary or at least much easier as in the past
The other reason is that in our days nearly every algorithm for specific problems is already written and easy to find in the Internet - so often programming is now more and more searching for already existing "parts" which when "only" have to be connected to each other.
And even when the improvements in Software development are ridicoulos slow compared to the improvements in the hardware modern development tools are getting better and also programming languages have definetly improved other the years (just compare the first version of Java with the actual one)

I've been programming for several years and have never used xor and xnor.
What am I even doing? Lol. 😅

I bet your compiled code has more xors in it than you realise - specifically every time you initialise a value to zero.
