I judge code by if human level observations of it running can tell the system needs 'time' to pass for it to complete or not. if humans can tell time needs to pass then you failed. If you can trick humans into thinking computers are instantaneous your succeeding. I would rather more companies and developers would take a similar stance and stop wasting the time of the people using their systems. Even if that means doing much less with computers until hardware is good enough to do everything "instantly".

I just want to say something on the topic of performance in general: it really depends. almost all companies have a very small customer base, small teams, small everything. only very few companies in the world actually have "real" performance issues to deal with. Like issues, where you literally have to invent new technologies to make something work. companies like google, amazon, tiktok and so on. So "performance" is almost always a bad argument, since it is not a priority in almost all companies and can almost always be easily solved by scaling vertically or horizontally.

People who read the book know that Casey's example wasn't clean code.

an alternative solution to the vacuum problem is `return "NNNNESSSSENNNNESSSSENNNN"`, if we just visit every point then we dont need to bother know where the dust is :)

haha I thought the first code was the easy version and I was waiting for more abstracted one. I come from Clean Code CQRS DDD C# world.

I have a question, when you show your php program, in side your while loop, I noticed the php starting and closing tags were switched. I’ve never seen that done before. What was the reason behind it?

some people model it as an "mathematics" problem. some people model it as an "english" problem. The mathematical solution is a simple, short and probably optimal solution but if you change a little bit of the scenario then you have to write the entire thing again and this is where the "english" solution seems more scalable. But I get your point: the problem is everyone enforcing that you should model in "english".

Lots of things to address... Ideally the purpose of various clean code things is for extensibility/coupling. It's a tradeoff. Of course it's bad/wrong to be universally applied when the tradeoff isn't in your favor. Second, every program does some form of modelling, modelling doesn't equal formulaic object oriented modelling. It's not a dichotomy, you can go for various levels of abstraction/indirection in different ways that make different tradeoffs for performance, legibility, and extensibility. You can avoid a using object oriented abstraction while still expressing your intent in your code.

You are making a good point. However this is all based on relatively simple problems. But maybe these are the problems that we have in web development and don't need full model-the-problem approach. Problems where you have e.g. human life at stake (automobile programs) need to be fullproof probably need different approach than standard web development. I am not trying to downgrade web problems here, I just think that web is more complicated than it really needs to be. There is nothing of value that comes from what I have written here since there is no clear substance. Have a good day.

Literally clicked on the video at 5am because I cant sleep. Thanks for the rant. Thanks for putting all that into words. Appreciate it.

Im going to go against the crowd here and say that the first example can be better. I disagree with "its easier to understand because its all in front of me". I mean yes, all else equal shorter code is better, but all else is not equal, and shorter code often demands more effort to understand what its doing, while slightly longer code with more abstraction can be more obvious and thus easier to understand. In the first example, you can treat each function as a black box and potentially understand, at a high level, what it's doing much faster than the second example, where you have to understand the computation of many or even every line to understand what its even doing. Now of course you can overdo it, and its extremely easy to overdo if you're not conscious of this. For example, i think your first example here is slightly overdone. But just like more abstraction isn't necessarily better, less abstraction isnt necessarily better either. I think the best is somewhere in the middle

David Whitney gives a talk, "Intentional Code (Minimalism in a World of Dogmatic Design)" where he says to burn your copies of Clean Code. Quite refreshing! And I love Dan North's CUPID properties as a replacement for SOLID

If you ask me to solve a problem, I'll try to solve that specific problem in a simple and straight-forward way. If you ask me to create a framework for solving a whole class of related problems...well that's a different thing entirely. You don't need a Domain Model if you don't have a domain. You don't need objects if you don't have to encapsulate state and methods away from other encapsulations of state and methods, etc. Complexity Must Be Justified. Clean Code is a great way to get developers to start thinking about the code they write in a qualitative way, but if it becomes a shackle that forces developers to become complacent or to stop being mindful, then it's a liability and should be jettisoned. Unfortunately with how dogmatic some people get about programming, A lot of people really fall into the second case.

I am in the midst of a project like this right now. The project was complete and working weeks ago. But then committees got a hold of it, and mutated it for no reason. Insane new workflows were added, with no benefit to the end product. And of course I get yelled at for missing the original deadline.

Getting Real book by 37signals talks about this.

Im not sure if i get the law entirely but i remember doing a analytics project were i built a dashboard that was of a very simplistic nature with straightforward KPIs just to familarise myself with the business. We also had an expert contractor built dashboard that was this amazing tool, with every aspect of analysis imaginable (which was as i found later, surplus to requirements). With this particular tool you could analyze the number of people who used it on a daily basis. Lol and mine was more used because i think most of the business found the expert built one a bit convoluted. It was a fluck on my part as i was just learning but I think when we are building things it is very important to communicate effectively with the ones you are going to be building for. And Really asking them if they actually think they'll use it.

OMG thank god I heard this. On any personal project I do(because of course I'm not currently employed as a SE), I never deliver a minimal viable product. I keep thinking of features this app 'could' use and the work items just increase rather than decrease. I definitely get stuck in the mud of having a 'perfect' app(that never releases) rather than a simple functioning app that offers the basic value without all the bells and whistles. I used to think it was a good thing I did because it'd make me a better developer but I can honestly see that it's the opposite after watching this. I'm going to try and focus on just getting something up and running and offering value. Good video!

Thanks for putting my thoughts and feelings into words.

What you're talking about is Cargo Cult Programming. There's a Wikipedia page dedicated to it and I have seen a few developers, like you, talk about it, but I have never met one in person.

The beauty of Tailwind is that you don't write styles any more, you just write the class names. I mean, sure, on top of CSS you also need to learn Tailwind, but think about all the bytes you're saving when you're sending HTML down the pipe!

"Performance is a secondary concern until it isn't." This is very much my experience professionally.

Nobody who advocates clean code is unaware that there is a performance hit. It's disingenuous to use small code examples to criticize clean code because clean code is meant to address coupling and manage dependencies in large systems. As systems get larger they naturally begin to modularize to make parts of it more cohesive and to manage coupling and competing business and team structural needs. Also, code is read many more times than it is written, and when you have a lot of it, you need to prioritize readability and testability over performance as high performance solutions are often not as readable.

Loving this content David, your videos are amazing and I need to comment on how soothing your voice is. Makes it for a really good listening experience. Have a good one!

I worked in a company that took clean code to stupid heights. The code scanner when you checked in even had clean code rules in it so you'd get flagged for stupid things like your functions being more than 5 lines in length etc. The entire codebase was an enormous pile of incredibly difficult to read spaghetti. Uncle "Bob" is a farking moron.

my take on this is: just make sure you do informed choices when programming, you have to balance both on not being a "corporate programming automaton" and not being a non-"good principles" cultist. use the tool is most fit on the problem at hand and, just sometimes, that tool might be that very-dreaded "abstract factory" pattern

i love you

When I first started code I felt there is something wrong but I couldn't put my finger on spot. The practices/the processed the bullshit buzzwords - the high ground elitist attitude from internet when questioning those things. Invested time in computer engineering/computer science/math/unix/functional programming now things are more clear. I feel its a spiritual warfare to fight against those tech diletants - they use big words factory of factories etc.. When in reality its a bluff of covering up their lack of expertise in problem domain. Glad I've found your youtube man, gathered tons of blogs links links with people talking about same bloat problems.

Well done David! I enjoyed listening as I was demystifying some over abstracted code.

I won't lie, I didn't want to watch it at first since it was so long and because I wasn't sure what it was about, but I'm happy I forced myself to watch it. Anyways, great video! And, I don't know how you do it, but every video I watch you somehow surprise me.

Only a software developer could come up with something so convoluted. Bravo! 👏 😊

10 mins in and really enjoying this. Good job, Dave 🙏

Great video, David (almost as good as Don't Model the Problem). Your dad sounds like a champ. Keep the content coming

The video at the end 😭😭🥹 sorry for all my screaming while you tried to play with Dad 😂😂

I think of 2 things. First, these design patterns, adaptability, testability and readability don't come into play until your programs grow. But you can't expect applicants to spend days on some silly exercise. Yet these aspects of software development are important for more seniority, so you want to test if the applicants have the required knowledge so you end up with some exercise which get over engineered. Second, performance might come into play for given parts of the program, rarely every part has to perform because of given bottlenecks. What is almost certain though is there will come changes. I agree on your closing statement, if you can argue why you think you have a better approach than what they had in mind, but they overrule you simply by dogmatic ways that's just dumb.

For what its worth I think you are a very excellent comunicator. I enjoy listening to you comment on things. I was also a big hypochondriac all my life. I think it ground me down so much that i literally didn't care if an ailment got me anymore. Im a lot more chill about it now. I have a couple of good and positive friends who've had similar issues and i am lucky for that. Anyhow, i think you are right to know hope we have to know our doubts. Best wishes my friend

David I feel you. I have been there. Less severe than what you are describing. Lift weights, take a walk once in a while, eat well, remove poisons as much a possible. Life is good. You are not that bad. Life is good.

Hey David, I hardly ever comment on videos but just wanted to say thanks for sharing and that you’re not alone in feeling this way. Sometimes things just feel shitty and it’s hard to pinpoint one reason. It’s even harder when you feel like you can’t explain yourself to other people. You’re not crazy, I completely understand your feelings and thoughts as I’ve shared many of them. You’re talented at expressing yourself and come across as very honest and thoughtful which is a refreshing change of pace compared to most UA-cam creators. It’s ok to slow down and take care of yourself. Best of luck

i get it man. ever since high school i was suicidally depressed. treatment resistant. no meds did anything for me, nor exercise, i kinda had some friends but only one irl, i knew i was too fucked up to have fulfilling friendships and relationships. nothing mattered to me and i was set that i’d rather die than work for the rest of my life. it was about 15 years of therapy, psych, hospitals, TMS, shock therapy, meds, panic attacks, loneliness, betrayal, failures, shit jobs, weird pains showing up no one could explain… i thought it would never end. things are different now. still not easy, and i still have terrible days. but i have to admit they’re not all terrible now. at least i feel like i somehow meant to be here and death is not the answer, that fear even if it shakes you to your very core is just a distraction from the truth. i forgot about faith, it didn’t make sense logically that things would work out. but you gotta let that go and choose to hope. i know now that no matter how deep in your bones you know something, you can always be wrong.

Sucks to hear man. After watching your 1st video a few weeks ago I was thinking 'Damn this guy is smart and has it together'. As a software dev for 3 years and now working a crappy unrelated job, I envied your position to seem so confident and smart. Goes to show what I take for granted like decent health. I hope things do get better for you genuinely. We all have our battles we are fighting

Touching video Dave, love the openness 🙏So needed in today’s world. You help more people than you know. Sending lots of support

Good video.

Have you tried going to the gym? It can help with your mental and physical health. It might seem like a chore at first, but once you start seeing your progress it can become fun. Start off slow with 30 min light intensity workouts and work your way up from that. Plenty of people feel the way you do. You need to find ways to take your mind off things.

Whats your metaphysics?

Hey, I have recently discovered your channel and found your videos really helpful. I am also a software engineer and can relate to most of the things you say in this video. Hopefully better days come to you David.

I send you a hug, thank you for sharing how you feel, hope you feel a little bit better sharing it.

I'm always here for you Dave <3

Health problems suck. I have a chronic skin desease and sometimes that overshadowes everything. Recognizing and cherishing the small and big victories throughout life keeps me going.

No comment I can think of seems adequate. So... Thanks for sharing
