52:30 Would argue this function is not great as it’s unclear if includeSetupAndTeardownPages supposedly modifies the pageData. Would be more clear and readable if it returned a value into a new variable.

Why do we need to plug a diameter of earth to other observations or even to calculate diameter when we have distance 350 mile as he saying and angle of 7 degree? With this information can be already calculated distance to the sun. Actually, with the same mechanism as in case of Sun, Moon and Earth.

1:48:18 it's meaningless to test "lines of code". Functions, components, yes. Individual lines, no. I'm not testing that ++i successfully increments i. That would be absurd.

1:24:50 what i find bizarre is that a function may take any number of arguments, while it may return up to one. Considering function arguments are sometimes passed by _reference_ it is immediatelly apparent that function arguments can _also_ be function _results_ . They become much more symmetrical once you change the function output to be simply a by-reference argument. "but then...?!" i hear you... yeah, yeah, yeah. Ultimately, _all_ code manipulates two stacks. The data stack and the return stack. What is being currently being handled and what is the program going to do next, so any function has access to two things, two stacks. So there is no need to _explicitly_ write them in every call. This way, every function call degenerates to its name. In one paragraph we arrived at forth.

Funny, cause there is a goto keyword in C#, and C# is pretty modern language; I tried it just for fun couple times. For instance, in "catch" block of try-catch (something wrong happened? - hey, let's go to the label a put before this place and try again xD)

In a collage exam where i was supposed to prove the existence of sequence of binary words suck that each neighboring elements differ in just one letter for every word size. I did so by writing a lisp program , in paper, that would generate the next sequence. Then I proved that it did that and used induction.

1:15:24 A double take is when you see something, and take it in as a normal perception; then an awareness of something in that perception causes you to look again (in surprise) to retake your perception. The idea is that there is a disparity between expected and actual perception.

What's wrong with C++? Java runs on a billion devices (That's what the banner claims during Java RTE install), and C runs on the entire rest... an C being the forefather of C++ ... how can someone hate C++? It gives you all the freedom that Java took away. (It is always up to the programmer to not misuse that freedom right?) I remember there were C/C++ haters around 20 to 15 years ago... but now with Python being so popular the Java vs C++ hate wars should have transformed to ancient history... Well I hate Java... (Had to say that here because Uncle Bob did not ask the audience if there are any Java haters around, only C++ haters). I like that guy, uncle Bob... "Why did they put lambdas into the language". I personally stick with C++ since Stroustrup published it. And C++ back then was so clear and easy ... now with all the lambda stuff and that pumped STL, is not really necessary as one can get away without... did so for 25 years.... Damned Lambdas. Lambada was fine... Lambda is not.

I know this doesn't have anything to do with the video, but I would like to share these questions and this message with as many people as possible. 1. What do you think happens to someone after they die? 2. Do you think there is an afterlife? 3. If heaven exists, how do you get there? 4. Would you be good enough to get into heaven? Here are a few questions to see if you are a good person: 1. How many lies have you told in your whole life? 2. Have you ever stolen? 3. Have you ever used God's name in vain? 4. Jesus said that "whoever looks at a woman to lust for her has already committed adultery with her in his heart" (Matthew 5:28). Have you ever looked with lust? 5. If you have broken any of these commandments, would you be innocent or guilty on Judgment Day? 6. Would you go to Heaven or Hell? The Bible says that "all liars shall have their part in the lake which burns with fire and brimstone" (Revelation 21:8) and "Those who indulge in sexual sin, or who worship idols, or commit adultery, or are male prostitutes, or practice homosexuality, or are thieves, or greedy people, or drunkards, or are abusive, or cheat people - none of these will inherit the Kingdom of God" (1 Corinthians 6:9-10). So, if you are guilty of any of the ten commandments, then you are in trouble when Judgment Day comes! Do you know what God did for guilty sinners so that we wouldn't have to go to Hell? 2,000 years ago, God became a human being, Jesus of Nazareth, who suffered and died on the cross for our sins and rose from the dead on the third day, defeating death. The punishment that we deserve for breaking God's law, Jesus took in our place. He paid the fine that we could never pay so that God can legally set us free by forgiving our sins. He is just, by punishing evil through Jesus’ death on the cross, while being rich in mercy towards us. What you have to do is repent, or confess and forsake your sins, and trust alone in Jesus Christ. Don't trust your own goodness, because, as Jesus said, “No one is good - except God alone” (Mark 10:18). Trust alone in the savior. The moment you do that, God will forgive every sin you have ever committed and grant you eternal life, and He will give you a new heart with new desires, so that you will love to do what is right. You will be born again. But you must repent and trust in Jesus. When are you going to do that? Here is a short Christian movie on this subject and depression: usshow.info/watch/fcqxzXMRGoc/video.html

I think the fact that many software developers call themselves engineers without a degree in engineering is poignant. That is a profession, with continuous improvement mandated, ethics, a professional body. Yet developers take the title and ignore what's behind it. That would be a good first step, or even parallel step. I find it astonishing that flight control software doesn't require a stamp to this day.

"if" statement fails. use more switch statements. Else is not default. By principle, coding is a language. A skill so much needed in the 21. century. If you can learn how to speak, you can learn how to code. But... Engineering principles like: math, physics, chemistry, etc., are what programmers desperately lack. Some just went and started coding apps to sell stuff or some social network bullshit that will fade away. I had a good friend who is an engineer like myself and he learned how to write some code in c. Soon he built an application for pc, and earned a title of the best programmer in this part of the world. The dude solved mapping problem of complex system of monitoring. I won't say which one, and he became the top one. He wasn't a good student. He troubled with math and all of those technical subjects but it didn't stop him from imagining. Still till today I have his scripts he wrote as the school learning material with my name on it as a co-author. I was good at those subjects and provided technical stuff, he was the one who had the vision of what it should look like.

I see developers are complaining about the presentation length but as an engineer, I really loved the way he framed the talk from the solar system to a java function. of course, what better example than a man who calculated the sun's distance at 250 bc without any modern tools to understand our lack of creativity and patience for shitty code.

The idea that a function should not be able to be extracted is wrong because then you loose the information about where and well it gets called. You should be using code blocks instead.

1:12:54 it’s not hard to see what a bool does as a function argument! Just peek at the function definition - if you have a proper name for the bool it should be clear as daylight! Having 2 separate functions instead of a bool can lead to convoluted naming as you need both DoStuffWithX and DoStuffWithoutX instead of just DoStuff(bool x). Also consider that you can use default parameters in many languages.

I used to buy Uncle Bob books. Now I watch these types of videos: usshow.info/watch/QM1iUe6IofM/video.html usshow.info/watch/21JlBOxgGwY/video.html Uncle Bob bases his business on books, chats and knowing many people suck at programming, not because his techniques are that great. They are applicable when software technologies and software engineers suck. Sad.
