[@natescode]

Microsoft has a list of design patterns. Many many resources exist already. Just takes practice

[@CaptTerrific]

This was a moment of epiphany for me as well, and I can't point to exactly when I started thinking this way. However, in much the same way, there was a time when everything "clicked" yet again, and I began thinking about technologies which were better suited to the patterns I wanted to implement. This helped not only in tech selection, but in allowing me to more deeply understand the tech stack I was often stuck with for a given project, and work around those limitations. It's a continuous cycle of learning :)

[@muhwyndham]

Finally someone can make what I observe into coherent words. I got this particular eyes open when I was forced to learn backend due to business circumstances and switch language and platform from Kotlin to Go. It opens my eyes because recognizing pattern is my only handholding when doing the switch. But now? Yeha I'm flying. I even have personal codebase that compiles into 1 portable binary but have 4 different language in it and use incredibly esoteric stack. But it still boils down to just MVC.

[@OzzyTheGiant]

Yep, with backend frameworks, they're all pretty similar: The app listens for requests, dispatches them to the appropriate request handler, runs some tasks for that request, then sends back a response. You might have additional services that need to be handled before or after the request is dispatched, so depending on your language and programming paradigm, this is handled either with middleware functions or dependency injection in OOP. That, and knowing the HTTP spec is pretty much all you need to know at a high level. Maybe you might need to learn concurrency using coroutines, threading, spawning processes for high performance tasks but there's not a lot to know at that level.

[@ScottzPlaylists]

What your calling patterns which is so generic, you could call it similar concepts, Iike Features, Capabilities, etc. 👏 Similar concepts exist in many Technologies. Organize them into Tables, Trees, Mind Maps, etc. 💡 Data is beautiful. I like to gather and organize information as I learn 👍 Graph Knowledge Bases seem like the best way to make sense of it all, it gets so complicated. Nodes represents Named Entities (Languages, Databases, Paradigms, Features, etc) Edges (lines between the Notes) represent relationships. Ex: [Python]------>> has paradigm >>-----[OOP-Object oriented programming, Functional Programming, etc ] ❤

[@UIEngineering101]

One similar pattern that has helped me level up is declarative vs imperative programming. Declarative programming paradigms like SQL, CSS, HTML makes writing and reading code so much easier OR the reason why React has superior DX compared to other frameworks. Similarly, IOC or Inversion of Control principle. It took my so much time to realize why it is so fundamental and important. It has helped me design better APIs when I'm authoring a library.

[@GaryWarman]

this is what I've been telling people for years. the more time you put into familiarizing yourself with software development, the more you identify first principles, the more you start to think in those primitives and variations thereof rather than higher level contexts like specific language details. at some point, you stop seeing code, and you start thinking in abstract units of computation, the patterns you speak of. it's like with language you start with coarse words and then learn to break them down to letters, and then you start to learn to process them as lexemes, morphemes, phonemes, and other grammatical units (even if only subconsciously). but that's the point of gaining understanding of a thing. you don't have to muck about in the inefficient and artificial high level idioms and "human friendly representations" and instead offload those to the subconscious so you can focus on the things you're actually trying to work on. programs are just machines after all. oh and proofs, a la the good ol' Curry-Howard Isomorphism. but the point of these structures is that they are continuously divisible down to their primitives, and at the end of the day all they are is just a whole bunch of those primitives stacked on each other in specific configurations (or shapes if you will) which interlink into even more specialized configurations until all interlinking is exhausted and what you have left is your beautiful piece of algorithmic machination yeah patterns are pretty lit. groups of primitives. the only thing I'd add is that it's really important that you have an exhaustive comprehension of those primitives, or at least as thorough as you can possibly manage. Just never let yourself believe that you've finally figured out everything there is to know about anything, and you'll never stop running out of things to know 😊

[@redleader2211]

Typescript propaganda confirmed.

[@aspiesoft]

I see 2 patterns: 0 and 1 the thing that generally annoys me about people obsessing over strong vs dynamic types, is that at the end of the day, all that's being stored is 0s and 1s. The physical hard drive doesn't care about data types. While you can use prefixes to represent a data type in the hard drive, and it is helpful when programing to know what kind of data you are dealing with, it's still just being stored as 0s and 1s. It's also being sent over the internet as 0s and 1s. at the end of the day, the client using the website doesn't care whether I used javascript, python, or c++, as long as the content loads fast enough from their perspective and looks good. This is also why I'm starting to spend more time with learning front-end development, because that's what the user will actually see and care about. That and AI will probably have the advantage on taking back-end jobs, compared to front-end jobs where creative design has an advantage.

[@calmhorizons]

Is this bad satire?

[@amadzarak7746]

This is so true brother. Understanding these concepts has made me almost “language agnostic” in my career. Yes I have preferences. But if u locked me in a room, and said I could not leave until I finish an app in a programming language I’ve never written in, I would eventually make it out.

[@moardub]

I think this explains what I've been experiencing recently. I'll learn something new and be like "wait but isn't that just like x, but a little different" and its because of this exact scenario where patterns are repeating in different, but similar ways. Thanks for this video!

[@tk_kushal]

Incredible video man! I don't usually comment on videos but you deserved it, keep it up 👍

[@T1Oracle]

In the MBTI this is intuitive vs sensing. Intuitive personalities zero in on patterns. Sensing personalities absorb and analyze details. The clash between the two can be frustrating. When I see the pattern, I don't want to go over every last detail. That's how I learned over 30 programming languages. I stopped worrying about the details and now I can make usable software in so many different technologies. Sure, a code review may have 1000 nitpicks (if it's something I'm less experienced with), but the end user is never going to care about those.

[@codebreaker4783]

Love this! I might also add that the ability to use different patters against each other, is what differentiates the good from the best. The ability to hold multiple patterns and architectural models in your mind, in addition to consider the future roadmap and then give a educated response is really difficult.

[@sylvereleipertz955]

[@yash1152]

0:19 what's difference in static-dynamic vs strong-weak typing? * static: hard coded types, right? * strong: unchangeable types, right? * does dynamic typed means inferred typing? * does weak typing means variable can change the type of stored value?

[@СергейМакеев-ж2н]

No, "inferred" is not "dynamic". Static means everything is decided *at compile-time,* with some types being explicit, and others being inferred. Dynamic means that types can only be decided at run-time. Weak means that a type mismatch (whether at compile-time or at run-time) *is not an error.* Instead, the language will try to auto-cast the variable to the type it needs to be.

[@anasouardini]

IDK why, but I feel like static types are way effective at preventing me from silly mistakes than dynamic ones!

[@calmhorizons]

It's no coincidence. Strong, static typing means things have to be well defined when the program compiles - it is quite literally a barrier to many silly mistakes that human brains are prone to make. I write most of my code in C# or SQL for work, but occasionally I have to use Python. And much as I love its simplicity for a quick script, building anything large or complex in it is poison to me. So many silly bugs that you have no chance of spotting without a lot of tedious testing. Strongly Typed for life. :D

The code we write is executed on some piece of hardware and the means by which that execution occurs is extremely important to understand. This is the only way that we can build systems that are performant, have conservative memory usage and are power conscious. Code that is too focused on patterns tends to be very slow and use a lot of memory and power. It is part of the reason that our software industry is in such a poor State and why programs of the past ran so much faster than they do today.
