#java coding question

[stickia404]

Node based coding... in Java. It has taken a few weeks, but I have the system done.

As well, amazingly commented code base that explains what about everything does.

And everything being ran as functions defined in a registry! Hi NeoForge

I think the system for reading the graph of nodes is unique also! Since, I have had... a bad time with the JavaStackLimit, I decided to have the core of my system be around avoiding it as much as possible. So instead of recursively asking what node connects to what node, 2 stacks are made, 1 holds what will be running after it is done finding, the other holds a search stack. Meaning it can get any part of the graph, and it should just find the right order of things.

And! Since the read method is different from the run method, I can hypothetically just read and serialize the given node stack, making it persist between restarts.

The running system is a little more complex than just a search.

First it starts a `for` loop of the stack of nodes, then it starts making the inputs for the node. It checks if the node has any inputs, if so, check the output type of the previous node, if it is equal to this node's input (or if this node's input takes in ANY) then dont error. After not erroring, add to the input array; or, if the input was not connected to anything, give it null. Repeat the last steps until there are no inputs left for this node.

Next, it runs the node. It does this by getting all the registered nodes (in a HashMap for some extra speed), then finding the associated function with that Key. Then it tries to run the function with the given inputs. If the function does not crash, it checks if the function outputted anything, if so put that into the Environment's HashMap of all node outputs. Finally, repeat the last 2 paragraphs until there are no more nodes. Then clear the output map, so there is no "bleed over"

So TLDR: get all nodes into a stack (avoiding duplicates), then run a For Each over that stack, check if the type of inputs/outputs match, if so run the node and put its outputs onto a HashMap of outputs so it only needs to be run once.

And ALL OF THIS just to be put into a silly minecraft mod. But hey, at least I am having fun!

brooooo does anyone know java or python bc im taking some virtual high school classes rn and im following along and dont understand shit and google is unhelpful bc everything i find is a paragraph of technobabble with no dictionary at the bottom, a subreddit full of the meanest old assholes that i never want to interact with especially about beginners stuff bc their advice seems to boil down to "yeah youll figure it out lol" or literal insults???, or a youtube channel that works for one thing but skips the next section that i ALSO need help with

[crying-in-converse]

i want to cry because on only the second day of my coding class its too hard and im never gonna be able to do it

Ok, I’ve delved into Twine Sugarcube a little and I’ve had some revelations I feel the need to share.

1. Sugarcube is the devil. I mean that in the nicest way possible. I thought I was coding before… nope! I’m going to learn it anyway because the breadth of stuff I can do is amazing and worth it, but holy hells is this hard. Which leads me to number 2…

2. My fellow IF authors who use Sugarcube, you are now like gods to me. Massive respect for you. 👊 Seriously, the time and effort it takes to create a story in this, and to do it so seamlessly as many of you do, is mind boggling.

3. I don’t feel I’ve given enough credit to Chapbook. You’ve seen me talk about the lack of a save system. But for a shorter story like Viatica (currently at 155k words with Rebellion ending and coding) I don’t feel it’s a massive deal breaker. It also has no easy way to display stats or inventory or a codex. I had to jerry rig my own stats passage.

But what it does well, it does exceptionally well. Chapbook is a complete out-of-the-box format and requires no previous CSS or HTML experience. It automatically formats everything for you, headers, footers, the adaptability to be read on any device, it’s all there. There is no style sheet to create, no Java script. The biggest challenge is coding choices and variables, but even then Chapbook comes with an easy to read guide that spells out everything you can possibly need. I would also be happy to answer questions or share screenshots of what I’ve done. If you’ve been wanting to try your hand at IFs but the idea of coding is daunting, you can use Chapbook. If you want to focus on the writing, your craft, and don’t have the time or inclination to heavily code, you can use Chapbook. If you’ve never coded a damn thing in your life and think CSS stands for “can’t style shit”, YOU CAN USE CHAPBOOK!

In conclusion, Sugarcube is evil incarnate, but I’m going to learn it anyway. Hail, Satan. Chapbook is mercy incarnate. Thank you, my lord and savior. And if you’re a newcomer and on the fence at all, I encourage you to give Chapbook a try. Say it with me… you can do it. 🤗

About the whole DOGE-will-rewrite Social Security's COBOL code in some new language thing, since this is a subject I have a whole lot of expertise in, a few anecdotes and thoughts.

Some time in the early 2000s I was doing some work with the real-time Java team at Sun, and there was a huge defense contractor with a peculiar query: Could we document how much memory an instance of every object type in the JDK uses? And could we guarantee that that number would never change, and definitely never grow, in any future Java version?

I remember discussing this with a few colleagues in a pub after work, and talking it through, and we all arrived at the conclusion that the only appropriate answer to this question as "Hell no." and that it was actually kind of idiotic.

Say you've written the code, in Java 5 or whatever, that launches nuclear missiles. You've tested it thoroughly, it's been reviewed six ways to Sunday because you do that with code like this (or you really, really, really should). It launches missiles and it works.

A new version of Java comes out. Do you upgrade? No, of course you don't upgrade. It works. Upgrading buys you nothing but risk. Why on earth would you? Because you could blow up the world 10 milliseconds sooner after someone pushes the button?

It launches fucking missiles. Of COURSE you don't do that.

There is zero reason to ever do that, and to anyone managing such a project who's a grownup, that's obvious. You don't fuck with things that work just to be one of the cool kids. Especially not when the thing that works is life-or-death (well, in this case, just death).

Another case: In the mid 2000s I trained some developers at Boeing. They had all this Fortran materials analysis code from the 70s - really fussy stuff, so you could do calculations like, if you have a sheet of composite material that is 2mm of this grade of aluminum bonded to that variety of fiberglass with this type of resin, and you drill a 1/2" hole in it, what is the effect on the strength of that airplane wing part when this amount of torque is applied at this angle. Really fussy, hard-to-do but when-it's-right-it's-right-forever stuff.

They were taking a very sane, smart approach to it: Leave the Fortran code as-is - it works, don't fuck with it - just build a nice, friendly graphical UI in Java on top of it that *calls* the code as-is.

We are used to broken software. The public has been trained to expect low quality as a fact of life - and the industry is rife with "agile" methodologies *designed* to churn out crappy software, because crappy guarantees a permanent ongoing revenue stream. It's an article of faith that everything is buggy (and if it isn't, we've got a process or two to sell you that will make it that way).

It's ironic. Every other form of engineering involves moving parts and things that wear and decay and break. Software has no moving parts. Done well, it should need *vastly* less maintenance than your car or the bridges it drives on. Software can actually be *finished* - it is heresy to say it, but given a well-defined problem, it is possible to actually *solve* it and move on, and not need to babysit or revisit it. In fact, most of our modern technological world is possible because of such solved problems. But we're trained to ignore that.

Yeah, COBOL is really long-in-the-tooth, and few people on earth want to code in it. But they have a working system with decades invested in addressing bugs and corner-cases.

Rewriting stuff - especially things that are life-and-death - in a fit of pique, or because of an emotional reaction to the technology used, or because you want to use the toys all the cool kids use - is idiotic. It's immaturity on display to the world.

Doing it with AI that's going to read COBOL code and churn something out in another language - so now you have code no human has read, written and understands - is simply insane. And the best software translators plus AI out there, is going to get things wrong - grievously wrong. And the odds of anyone figuring out what or where before it leads to disaster are low, never mind tracing that back to the original code and figuring out what that was supposed to do.

They probably should find their way off COBOL simply because people who know it and want to endure using it are hard to find and expensive. But you do that gradually, walling off parts of the system that work already and calling them from your language-du-jour, not building any new parts of the system in COBOL, and when you do need to make a change in one of those walled off sections, you migrate just that part.

We're basically talking about something like replacing the engine of a plane while it's flying. Now, do you do that a part-at-a-time with the ability to put back any piece where the new version fails? Or does it sound like a fine idea to vaporize the existing engine and beam in an object which a next-word-prediction software *says* is a contraption that does all the things the old engine did, and hope you don't crash?

The people involved in this have ZERO technical judgement.

I try to make a balance between reading the book "Kafka: The Definitive Guide - 2nd Edition," doing Confluent course lab exercises, and a little bit of Udemy projects with Kafka as well. In the middle of the week, I'm making my homepage to showcase some portfolio stuff, which is not my priority at this time, but it involves a lot of coding as well.

Feeling like I can answer any interview questions about Kafka at this point, including the fundamentals, use cases, and examples of writing a pub/sub system in Java.

It's all about studying; it magically changes you inside and out. You're the same person, in the same place, but now capable of creating really good software with refined techniques.

[cccc-ask]

My goodness, a fourth set of parts that are permitting asks? How many are there? I clearly need to do more research… Anyways, I suppose that I now must ask this set’s Mind the same question I did the others.

To Mind: Preferred coding language? Of course, if you have a preferred one that is.

HELP i just bombed a live coding interview and it was a relatively easy question (print a 30x30 matrix in spiral form).. i talked out my solution and he said it made sense but when i actually needed to start coding. i just. BLANKED. i was coding in python and asked to switch to java bc i thought i'd know how to do it there. and then i ALSO BLANKED. COULDN'T INITIALIZE A 2D MATRIX IN PYTHON OR JAVA EVEN AFTER GOOGLING. cringe moment. do u have any live coding horror stories to make me feel better

i interviewed at vine and almost burst into tears because i forgot objective C. dont worry about it
