ITkonekt 2019 | Robert C. Martin (Uncle Bob), Clean Architecture and Design

TOPIC: Clean Architecture and Design
So we’ve heard the message about Clean Code. And we’ve been practicing TDD for some time now. But what about architecture and design? Don’t we have to worry about that?
Or is it enough that we keep our functions small, and write lots of tests? In this talk, Uncle Bob talks about the next level up. What is the goal of architecture and design?
What makes a design clean? How can we evolve our systems towards clean architectures and designs in an incremental Agile way.

@@VinayAggarwal While I agree it's a great presentation, I just wish he would switch it up. He's been giving the SAME exact talk for about two decades now. He just throws in a few new points here and there. I feel like a lot of corporate entities have seen his talks and think it will, "boost morale" to have him at their presentations. He's obviously extremely knowledgeable and I wish he'd just actually speak his mind instead of sticking to this tired old script.

[@NotARealPerson12345]

I watched his another similar presentation a few years back and did not quite get it. It took me a few years to finally realize what he really means. The presentation itself is brilliant, but rather high-level, not easy for a junior programmer to fullly grasp. But man, everything he said is nothing but truth.

[@JohnDoe-sp3dc]

It's not, "high level" it just has more to do with social issues and programming theory than it does with computer science or engineering.

[@GoWokeGoBroke1]

You mean low-level

The total numbers of software developers in the world for 2018 was: 23 Million, according to Evans Data Corporation, which regularly conducts in-depth surveys of the global developer population. It is expected to reach 27.7 Million until 2023. So it's just 20% growth in 5 years, which is pretty far from doubling.

[@banu6301]

Alan Turing became the first developer in 1942. 2022-1942 = 80 years 80/5 = 16 doubleings So if it doubled every 5 years that means that there should be 2^16 developers. There are 27.000k devs and not 65k, which means that it way more than doubled every 5 years (on average) The last years it didn't double anymore but the average is still the average, you can't take a small sample of the data and call it a day. In 1943 I bet there were more than 100 developers already which would make this statistic as "100x more devs per year" Edit: he said 1946 but from google I got 1942 (the engima machine) nevertheless the math is still pretty much the same for a 4 year diff

[@unforgive2n]

i just love the way Uncle Bob is into science 👍👍

[@maximpobihun5469]

The smartphone has many processors except the main processor, such as image processor, 2D/3D graphics processor, audio processor e.t.c, but these processors usually do not run on software that is written by software engineers/programmers. Most of those processors are DSP - Digital Signal Processors that are designed by hardware engineers. Also the logic with if statements, algorithms in many cases can be implemented on hardware level without any software involved.

[@maincorvus2243]

Software as in logic, discreet mathematics sciences. It's relevant to his point whether the logic happens at the software or hardware level. Implementing logic using hardware is programming. I hope that helps.

I don't get all the hate for the cameraman. He did a very decent job. The bad guy here is the lazy editor who just didn't care about the viewers.

[@nwoDekaTsyawlA]

I would agree if there was more than one camera, the second one pointing to the slides. Here it looks like there is only one camera, so the operator should pan out to the slides...

I really wish their was an architecture that removes programming language dependency too. That way I can easily shift my entities and use cases and contracts to some other language with hustle of converting em.

[@gruttewibe76]

You have to express them in /some/ language. Nothing is going to solve that. Converting between languages is easy though if the code has no (other) technology dependencies. There are converters, and supposedly AI does a good job at it too.

I heard that the issue of toyota is people stepping on the wrong pedal, not that the code didn't work in the car. It was that people panicked and pressed on the accelerator pedal harder instead of the brake pedal.

[@BlackMan890]

You need to learn better history. You are completely and utterly wrong. It was a horrible horrible spaghetti-long single-function code running in a non-ECC cpu that, from the constant vibrations of the car, could effectively lock the entire code out. There's a wonderful transcription from an expert programmer witness who was allowed to view and read and examine the code from the Toyota car and the horrific things he described would make any programmer run away from any toyota car.
