Another good tip: when you get a massive amount of compiler errors, only look at the first or last error, solve that and try to recompile. This can be a huge help to keep you focused on the right thing when working in languages like C++ and C#, where 1 thing is written wrong, and the compiler keeps chugging along trying no matter how confused it gets. Most of the errors are nonsense, and only 1 needs you to fix it (which I almost always have seen to be the first or the last error).

I was working on a microcontroller project and I had this strange bug that took me weeks to fix. What I learned is that the branch prediction hardware while executing assembly code was different for 2 different chips that were the exact same except for the temperature rating. I looked through the errata for the chips and nothing was documented about it. The way the bug worked was on the chip with the slightly higher temperature rating, only during specific interrupt routines, certain instructions would take 4 clock cycles on 1 chip and only 3 on another chip, making my timing-critical application take 1/3rd longer only during very specific times. I looked through everything, the oscillator, the all the different registers for controlling the clock, the oscillator calibration registers that came factory calibrated with the chip, but in the end the 2 chips acted the exact same at every other time except for in that interrupt routine. One of the few cases I've found where it was literally my chip fabricator's fault my code didn't work.

Google-fu is a black art few learn well, but those who do, will find the exact stack overflow answer they need every time (unless it doesn't exist). But seriously, learning what parts of an error are worth using and when and how to use keywords in your search make finding answers much easier. I don't do js, but someone messaged me about a problem that involved settimeout inside a while loop. All I needed to google was "settimeout inside while loop js" and boom, the answer.

Testing: If you're solving an algorithmic problem, it's good to code a brute force solution as well, if only so you have a reference solution that you know is very likely to be correct. Then you can test your optimized solution(s) against the very likely correct brute force solution. Bonus points if you write a piece of code that generates test inputs, then you can get the expected output by feeding the generated input into the brute force solution.

I expected this to be a tutorial on how to defensively write code. I think the biggest hallmarks to being an experienced developer is that you write less bugs. Mostly because you spot them right away since you've seen them before, but also because you avoid common pitfalls and protect yourself from them before they happen. For example by utilizing design patterns or testing procedures you're unsure about before spaghettiing it into your code.

how to never write bug? write code do good
Unit testing is the best tool you'll ever get. Don't forget to test for errors and not for passing results. Sure it seems to slow your coding high, but if your project gets large, it's the contrary. It forces you to break your code into relevant testable components. Mocking data for tests helps understanding your code deeper. Time saver: It's also wonderful once you automate all tests. Example of a mono repo with a lot of common dependencies. Update one dep, rerun all tests for all modules in your repo. If anything breaks or changes, the unit tests will catch it for you. Documented clean tests can also serve as documentation for personal projects.
7:12 Best anti-smoke ad I've even seen!
I've learned in my life as a programmer and a technician that one rule always prevails when it comes to troubleshooting, if your work has caused an issue...., check your own shit out (code, test setup, wiring, installation, etc.), because the mistake is almost always going to be yours.
always make sure that the function you are debugging is being called.
I've been scripting in Lua for a few years (JS for only a few months), fully self-taught meaning I make many mistakes. What I've realized works best for my workflow is to just make it work inefficiently first to have an idea of how I want it to work. Looking for alternative ways to run a specific piece of code is easy, since it isn't even close to completion. Then recreate everything in a well documented and well optimized way while adding user friendly debug or logging functionality just in case.

One thing you didn't mention is the Tanos' method. It's perfect whenever you have no idea how a big chunk of code works, but you need to fix a bug which is ideally producing some error message. The method requires you to comment out half of the code, then check if the error still persists. If it still persist, then you need to call Avengers and bring back that half of the code, but then you need to comment the other half. When you found your faulty half and still don't get where the error is, comment out a smaller half (a quarter to be precise) and so on

a few more, for good measure: • by far the quickest, simplest, and most efficient way to do something is **not to do it.** when writing a complex program, periodically check to see that everything you're doing is truly necessary. you would be surprised how often you find entire swaths of code that can be deleted. • if touching grass for a while and returning to the problem doesn't work, try explaining how your code works step by step to an inanimate object, such as a rubber ducky. very frequently, you will find that you catch the problem as you explain it. • unionize your workplace at the earliest opportunity. this also applies to other jobs. • avoid OOP at all costs. most things do *not* need to be objects. • If the language you're using is dynamically typed, such as Python, pretend that it isn't. don't change the type of data in a variable - do not be tempted. • ensure that your program has as little "state" as possible - keep track of everything that you have to, but no more. • your time is far more valuable than a computer's. don't worry about tiny micro-optimisations unless you *really* need to. • familiarize yourself with your language's standard libraries and save yourself the pain of wasting time writing your own, worse implementations. a lot of this can be summarized with a quote from Jack Diederich - "I hate code, and I want as little of it as possible in our product."

I'd add that if you are not sure whether a new piece of code will work or be bugged, it is reasonable to make a copy of main file and try it there, in case you add a lot and make a mistake somewhere deep in the code and have to review whole file for all interactions. Or make a separate file to test that specific feature before implementing it in actual file.

It's literally here: 4:54
“take a break” is the best possible advice. Even just a brisk walk outside with fresh air
The worst is when the error message have nothing to do with the actual error. Either because there is a try/catch somewhere that rethrow a different error without linking the original error. Or because the error shown was assumed by the developper to be something when it could be something else.
New debugging tip: Copy and paste code to chat GPT 🤣🤣🤣

I think they should build an ai debugger
I like the shade thrown at Java. I've been forced to use Java because I work a lot with graphs (neo4j). It constantly amazes me just how ugly the code is. The simple fact that you can't compare strings with the equals signs or overload the operators to fix it is insane to me. Having an extremely dated package manager that barely works (Maven) is the icing on the cake. Java measurably makes my life worse.

Agreed. Java: why write 10 lines of code when 100 will do...

It does make me curious why Notch decided to go ahead and write Minecraft in it then. Was it mainly just because that was the language he knew/was using at the time?
That randomness joke was solid af. You still got it Fireship lol

i like just started using c# (first time ever programming) and i have gotten pretty good with getting rid of my bugs
Great Video. Please make one about debugging race conditions.
this channel is pure gold
Very good your class of tecnology
bonus tip is true, many times I figured out how to write the code was right before falling asleep or short after waking up
