I'll pass on commenting on other channels, but here's some insights into mine. I am a full time software engineer with a specialization in front-end single page applications. I am also a dad with 5 kids who deserve my attention. This leaves me with a limited amount of free time for hobbies. Sharing my perspective on things lets me use the creative side of my brain (making videos) and combine that with something else I enjoy (encouraging friends to relatives to consider software development).
So, why don't I do tutorials. There are a couple of reasons. First, my employment agreement states that my employer owns the code I write, unless I go through a process to get permission through their attorneys. (Too much hassle). Second, there are a ton of good coding resources out there. Third, it takes a lot of time to produce quality tutorials. Fourth, I've done a couple of tutorial style of videos for my employers and for me, making that style of videos is boring, which seems strange because I really enjoy writing software. I'm just not going to cut into more family time to reinvent the wheel on something I don't enjoy and would enjoy even less if I had to involve attorneys.
Instead I share my perspective on my specialization and the path I took to get there since that can be helpful for people who are in a similar situation and considering a similar path. The industry is so large and everyone's paths will be different so naturally my perspective won't be the right answer for everyone. I'm not going to pretend to be an expert in areas outside of my zone. Even within my my specializations there are differences of opinions, especially since no framework or library is perfect for everything. Do you choose to focus on learning the best framework no one uses or an imperfect framework that is popular when trying to get a job?
Also, everyone is at different stages in the journey, which requires different levels of explanation. Naturally, it's impossible to make videos that work for everyone's interests, priorities and skill levels. Sounds like your priority at the moment is tutorials, which is great. I hope you find some excellent ones. That won't be my channel. If you aren't interested in single page applications with React or Angular then there's probably other channels that better fit your needs. Either way, thanks for stopping by and sharing your perspective. I'm sure a lot of people share your same feelings or frustrations. I hope you have a great day and wish you success on your journey!

Been getting some questions on why I left crypto. Not the point of this video but here you go... I just feel the ecosystem is too overhyped, not enough solid actual use cases that make sense and rampant with speculation and sketchy projects. Everyone has to create a token. I mean how would it be if each grocery store had it's own currency and you had to exchange currency to buy stuff and then try to figure out which store had a better deal. Eventually some actual companies will come out of this with good ideas, and when that happens, I'll see.I also want to see some more accountability. Some people think that because a contract is written solidly that a system is safe. Problem is there is usually a UI and server in between that can be buggy. If something glitches you can lose money irreversibly and there's not a lot of accountability for those who wrote buggy code.
This was one of my concerns going into it, then it actually happened to me. I personally lost several thousand dollars in a similar scenario. The team tried to blame it on me, though I used their own UI. It could have been avoided with simple validation on their end, which obviously didn't exist. It was an intermittent bug because other transaction went through fine, but I was not the only one that had this happen based on the records. There was no way to recover the money. Right now it's mostly speculators in the space. For true mainstream adoption, you can't have that happening. Normal folks won't accept that. Nor will they accept having to do 98 confirmations on a hardware wallet for a single transaction. That happened to me once.
Figuring out taxes is still painful too and the decentralized argument is somewhat half baked since there are so many centralized bottlenecks in the systems. Some people will continue to make a ton of money speculating in the space, but right now I'm back to investing things where it's easier to come to valuations grounded in business fundamentals. Once things mature some more, I'll consider it again. But that's probably a couple years out. A bit long winded, but that's where I'm at.

gotcha. with algorithm type questions i would try to figure it out and then once totally stuck. look up solutions to the problem. preferably ones that explain what's going on. over time you will start to see patterns and you will at least know how to solve that pattern portion. try to figure out the rest until you get stuck and then repeat the process.
over time it gets better. that said, unless you are rigorously studying algorithms, more complicated ones can take some time to process and in real work situations one would search for a solution, a library that provides optimized solutions to leverage and then if your use case is custom, you might have to roll your own. this whole process will be hard at first. what you are experiencing is normal.
For the example you gave, to create a simple palindrome you could start with a string, create a copy of the string, reverse the copy and then join the two. To determine if a string is a palindrome if there is an even number of characters you could split the string in half. flip one side and compare the two for equality. if odd number you can't split cleanly so you would have to handle that. there are also different ways to approach things. for example, a different approach would be to focus on the tracking the first and last index values and compare them then iterate toward the center of the list making comparisons at each step.
or if it is a palindrome of words in a sentence (not a true palindrome, more of a chiasmus) you would have to do it a little differently since just reversion would ruin the words. you would end up splitting the string at spaces into an array of words and do something similar to early. create a copy, reverse the copy. combine the arrays and then join each work back into a string while adding spaces back in.
A lot of times it helps to write it out like i did and then focus on each step in writing the code.

@LoriWolfcat to keep things easier to figure out, it is a good practice to break an app down into smaller components. i haven't worked in swift or built android apps. i have a little experience with java but most work on web apps with javascript. java has more boilerplate than javascript so keep that in mind. if i were to build plants vs zombies, there would be a tone of components. let's only focus on a small piece. the zombies. you might have a class file that represents a zombie to keep track of the type of zombie, location, proximity to others, damage, etc. each type of zombie may have its own file to extend the main class for basic functionality and then this other file adds unique behavior. for each zombie you will have a file to handle the animation and styling. then there is the image files. the could be utility files for common functions you want to reuse. there are the unit test files. there could easily be 30-40 files just related to zombies. then you have to worry about every other object, the game field, the game play scenarios, not to mention all of the boilerplate needed to run the application. it grows quickly and managing all that from an ipad may be doable, but won't be effecient or fun. imo. i would probably take a used 8 year old macbook over the ipad for programming if i had to make a choice.
