Preface: i'm pretty... definitely wasted. rum is amazing.
anyway, I spent today fighting with ActionCable. but as per usu, here's the rant's backstory:
I spent two or three days fighting with ActionCable a few weeks ago. idr how long because I had a 102*f fever at the time, but I managed to write a chat client frontend in React that hooked up to API Guy's copypasta backend. (He literally just copy/pasted it from a chat app tutorial. gg). My code wasn't great, but it did most of what it needed to do. It set up a websocket, had listeners for the various events, connected to the ActionCable server and channel, and wrote out updates to the DOM as they came in. It worked pretty well.
Back to the present!
I spent today trying to get the rest to work, which basically amounted to just fetching historical messages from the server. Turns out that's actually really hard to do, especially when THE FKING OFFICIAL DOCUMENTATION'S EXAMPLES ARE WRONG! Seriously, that crap has scoping and (coffeescript) syntax errors; it doesn't even run. but I didn't know that until the end, because seriously, who posts broken code on official docs? ugh! I spent five hours torturing my code in an effort to get it to work (plus however many more back when I had a fever), only to discover that the examples themselves are broken. No wonder I never got it working!
So, I rooted around for more tutorials or blogs or anything else with functional sample code. Basically every example out there is the same goddamn chat app tutorial with their own commentary. Remember that copy/paste? yeah, that's the one. Still pissed off about that. Also: that tutorial doesn't fetch history, or do anything other than the most basic functionality that I had already written. Totally useless to me.
After quite a bit of searching, the only semi-decent resource I was able to find was a blog from 2015 that's entirely written in Japanese. No, I can't read more than a handful of words, but I've been using it as a reference because its code is seriously more helpful than what's on official Rails docs. -_-
Still never got it to work, though. but after those five futile hours of fighting with the same crap, I sort of gave up and did something else.
zzz.
Anyway.
The moral of the story is that if you publish broken code examples beacuse you didn't even fking bother to test them first, some extremely pissed off and vindictive and fashionable developer will totally waterboard the hell out of you for the cumulative total of her wasted development time because screw you and your goddamn laziness.8 -
I'm starting to realize, that if you just know the basics of researching, you can (most of the time) find better free resources, than paid ones, for learning about new things in this field.5

This isn’t gonna be a random because I do eventually get to a Tech and YouTube related topic.
YouTube is actually killing itself with all of the dumbass rules they’re implementing. Trying to child proof or limit educational content is genuinely a shit policy. The reason so many gaming channels are switching to twitch because it doesn’t try to censor you.
But now I don’t know if you’ve heard but YouTube updated their guidelines and they’re no longer allowing content that teaches people about Hacking essentially (and I hate putting it like that but I can’t remember the exact words they used Hacking just summarizes it) which is fucking ridiculous like what the fuck else, are they gonna stop allowing lock picking videos?
YouTube has always been an amazing FREE resource for people learning Programming, Cyber Security, IT related fields, and even shit like lock picking, cooking, car stuff, and all that stuff. Even sometimes when the tutorials aren’t as detailed or helpful to me they might be exactly what someone else needed. And Cyber Security can be a difficult topic to learn for free. It’s not impossible far from it, but YouTube being there was always great. And to think that a lot of those could be taken down and all of the Security based channels could either lose all revenue or just be terminated is terrifying for everyone but more so them.
A lot of people and schools rely on YouTube for education and to learn from. It’s not like YouTube is the only resource and I understand they don’t want to be liable for teaching people that use these skills for malicious purposes but script kiddies and malicious people can easily get the same knowledge. Or pay someone to give them what they want. But that’s unfair to the people that don’t use the information maliciously.
It’s the same for the channels of different topics can’t even swear and it’s ridiculous there’s so many better options than just banning it. Like FUCK kids nowadays hear swearing from their older siblings, parents, friends, and TV it’s inevitable whether someone swears or not and YouTube is not our parents, they aren’t CBS, so stop child proofing the fucking site and let us learn. Fuck.
TLDR YouTube is banning educational hacking videos and are being retarded with rules in general16 -
C is love, C is life.
Great language.
I genuinely don't get why so many people are struggling with pointers, considering it's a pretty straightforward concept. I understand that they can be complex in simplicity, but the concept itself is much easier to understand than say, references in OOP languages(despite being the same thing under the hood).
I mean it's just a number like any other number, except that number is treated as a memory address, and the star(* - dereference operator) just takes a value, goes to the memory address that is the value, and takes a value from there.
I feel like most explanations and tutorials just try to over complicate it for no reason.27 -
So at the HS I go to, there are 4~5 programmers (only 3 real "experienced" ones though including me).
So coming from JS & Python, I hate Java (especially for robotics) and prefer C++ (through some basic tutorials).
Programmer Nº2 is great at everything, loves Objective-C, Swift, Python, and to a certain extent Java.
Programmer Nº3 loves Python and used to do lots of C#, dislikes Java and appreciates Go (not much experience).
So naturally I get shit on (playfully) because of my JS background, because they don't understand many aspects of it. They hate the DOM manipulation (which is dislike too tbh), but especially OOP in JS, string/int manipulation, certain methods and HOISTING.
So, IDK if Java or C++ (super limited in them) have hoisting, but if you don't know what hoisting is, it means that you can define a variable, use it before assigning a value, and the code will still run. It also means that you can use a variable before defining it and assigning a value to it.
So in JS you can define a variable, assign no value to it, use it in a function for instance, and then assign a value after calling the function, like so:
var y;
function hi(x) {
console.log(y + " " + x);
y = "hi";
}
hi("bob");
output: undefined bob
And, as said before, you can use a variable before defining it - without causing any errors.
Since I can barely express myself, here is an example:
JS code:
function hi(x) {
console.log(y + " " + x);
var y = "hi";
}
hi("bob");
output: undefined bob
So my friends are like: WTF?? Doesn't that produce an Error of some sort?
- Well no kiddo, it might not make sense to you, and you can trash talk JS and its architecture all you want, but this somehow, sometimes IS useful.
No real point/punchline to this story, but it makes me laugh (internally), and since I really want to say it and my family is shit with computers, I posted it here.
I know many of you hate JS BTW, so I'm prepared to get trashed/downvoted back to the Earth's crust like a StackOverflow question.6 -
There is so much confusion in the world of programming right now, at least for me. I bet there’s only so many concepts going on and that these concepts are realized in certain ways. E.g. programming following certain paradigms and practices, also different workflows, containerization, agile, devops etc.
When searching for tutorials in different subjects it’s horribly aggravating to learn to use the tools. Not because they are inherently hard or bad in any way. There’s just so many different tutorials, some badly given, some that are great but which bring up to many foundations you already know so you find yourself getting bored to the point that you just stop listening. Many tools are used for so many use cases, sometimes overlapping each other, they use concepts to that you’ve heard hundreds of times before. Many times they want to do things in a special way so even if the concepts are the same you still need to fucking listen to the same old thing while learning how to write a command a slightly different way or how some tool is supposedly better than another.
I’m realizing that what I’m so sick of is the lack of TLDR information about new tools with some short description of how to use. Where you didn’t have to re-hear stuff you already knew or had heard so many times unless for a very good purpose, such as to show exactly how it’s done differently than another relevant tool. In a dream world the TLDR information could also remember my skills and remove the parts I didn’t need to know about any new tool.6 -
Rant!
Beginner tutorials are great.
Personal project UE4 (Unreal Engine Game Dev)
I'm having this bug where I dynamically draw every tick into a Uncanvas. (C++) First I call .ClearChildern and after I create UserWidgets by calling blueprint to fill text.
Text is Invisible when drawn in native tick
I works. If I don't do it in the NativeTick
Search Online: "UE4 UMG text dissappears"
Result: How to create a Button in UMG
Me: No I'm creating a complex UI system
Search Online: UE4 Issue with UMG Text disappears when drawn in native tick
Result: How to create textfield UMG with blueprints
Me: No I have a weird bug and trying to figure out why that is!

have seen 50 tutorials on how to do the basics.
My problem with certain applications that there are so many tutorials out there that Sirius shit is hidden behind a cloud of beginners content.2 -
Today I had the chance to participate as a community member of an ecommerce platform to represent the community and vendor towards developers that are getting in touch with a new product from the vendor. This event was completely covered by the vendor and was awesome in many different ways. Features, tutorials, workshop, presentation, attendees.
Previously I worked on a closed source patent management software and one felt stuck and rigid. The only contact outside were customers. They were sort of the community and friendly as well just without technical knowledge. Events with the customers with a hands on the product was also covered by the vendor and great in their kind.
I am unsure what the reason for the different feeling towards this is. Is it about being a dev at a company that let me participate on a vendor product compared to be the vendor? Is it about the product license? The external people being devs or no-devs? Do you have similar experiences after switching jobs?
They were both friendly so it is not just about people being nice. Both products dont personally affect me as I neither file a patent or trademark myself nor do I own a web shop. -
I saw many great tutorials here and there(YouTube) and they are amazing but are they really that's all needed to be a pro or above intermediate level in it like
Flutter many tutorials on YouTube to clone ui make firebase backend but are they sufficient ?
I saw few on react and node is but they seem ok that's beginner level for ya. And that was all
Other then that nothing was there. Just a bunch of projects which people make and name Instagram clone , this clone ,that clone !
So what is the way you professional guys learn old languages (Java , cpp etc ) books /docs ?
And for new languages like flutter! how do you get into them ?
I should be sophomore in CSEnginerring major
