Custom Disc Installation Guide for Hermitcraft Season 9
I've seen a lot of people struggle with specifically the custom discs, so I made a guide on how to install the mods! It was originally posted as a twitter thread, along with a guide on how to get the world download.
How to install the Custom Discs mod for Decked Out / Hermitcraft 9 world download. Note: I'm assuming you already have the world installed. If you don't know how to do that, you can follow my previous guide here.
1) Follow this link https://oracle.com/java/technologies/downloads/#jdk17-windows…
2) Scroll down and download the "x64 Installer" (or whatever is more convenient for you).
3) Open your Downloads folder and double click - you may need to right click and "Run as Administrator" if it's not working. Then, click Yes and install the program.
4) The installation software should then open. Just follow the instructions and press Next, Next, and then Close.
5) Open up the Hermitcraft world download. You may have seen the "To play Decked Out as the hermits experienced it..." message in chat. Click on "[Click here]".
6) Press the first link ("Hermitcraft runs on Fabric [link]")
7) Press the download button, then Download for Windows
8) Double click the fabric-installer to open.
9) MAKE SURE THE VERSION IS 1.20! Leave everything else as their defaults. Make sure "Create Profile" is checked. Then, press "Install". - If you can't install, open your normal Minecraft launcher and run 1.20, then close Minecraft.
10) Go back to the Hermitcraft world and download the other three mods. Make sure you download all three of them!
11) Open your Minecraft Launcher and go to Installations. You should see "fabric-loader-1.20". Hover over it and press the folder icon on the right hand side
12) Open the "mods" folder. If you don't have one, create a new folder and name it "mods" (no capitals or punctuation)
13) Drag and drop the three mods you just downloaded into the "mods" folder.
14) Close Minecraft, and then press "Play" on the Fabric installation
Open Singleplayer, and then your hermitcraft world, and everything should be in working order! To get to Decked Out, you can either visit by the Nether Hub (DO is East/Red 2), or teleport by: /tp -523 103 2171
If you have any issues, feel free to reblog / comment with your problem (with a screenshot of your issue if you have one) and I'll be happy to help.
Good luck, and happy running!
#istg it's an entirely different experience when you get the custom sounds working it's like. amazing#hermitcraft#hermitcraft season 9#hermitcraft world download#decked out 2#scarland#sorry for clogging the tags these are just the two most sound-based experiences i've seen people struggle with#strbylmn posts

I work for insane people
So… I started work a few months ago and...
I keep being impressed with corporations lowering my expectations.
Like. EVERY time I think "Surely, this is as incompetent as it gets".
The boss is nice, the workers are nice, every PERSON is great so far. But the firm is just… fucked in ways that makes it hard to not scream with laughter.
It is like working in the ministry of silly walks by Monty Python. Insane things are happening, and everyone just acts like it is normal.
A dude was stating to someone else near me, that despite the costumers saying they did not want it, his code that crashed the application once a day, was NECESSARY, because writing code without memory leaks in C is basically impossible. Like… I just have all these small moments of insanity. Completely disconnected from each-other
My boss showing me and the other 3 new hires the coffee room, where a big screen proudly shows that not a single software product have 100% code coverage… as in, not a single person in this entire building filled with software people knows how code coverage works. He then points out an empty bowl, and declares "Twice a week, there is a fruit event". By which he means, fresh fruit is provided, and people can just grab some…. just said by a alien who is pretending to be human. Badly.
He then explained that the 2 coffee machines in here makes bad coffee. He then takes us to the copy room, showing us that THIS is where the GOOD coffee machine is. Which only takes coffee beans from a SPECIFIC vendor (Is… is the coffee machine… sponsored????)
He briefly pets the Foosball table (Again, in the copy room), which is jammed up against the wall so you can only reach the controls on one side ( Because, again, it is a copy room, and there is not enough space for it ) and he exclaims "Ahhhh… Not enough people are using this"
Suggesting, that he is trying to promote the little known sport "Single-player Foosball">
I start setting up my work PC and... Whenever any of the developers in this place wants to install things on their PC's, including compilers and testing frameworks, they have to either use the "SOFTWARE CENTER" program, which installs it FOR you… or in 10% of the cases, fails, without giving you any context for why it did that, and no tools for fixing it. Is it missing a dependency? Not working with the OS? Who knows!
Some programs cannot be installed like this though, because the SOFTWARE CENTER is not updated a lot. And when you want to install something the normal way… You get a popup, where you must provide a written explanation for why you need to have temporary admin rights to your own dang PC … you then submit that, and your screen will then be watched remotely by a worker from India, for a varied amount of time you are not told…
Or at least it says so. Maybe the Indian dude watching me is just an empty threat. Who knows. But they get to see me running absolutely… BONKERS .bat files
Like, I CHECKED them, and a good 80% of them calls a Power-Shell script in the folder above it, called "YES_OR_NO.ps1" which opens a windows 95 window informing you that DURING INSTALLATION YOU MAY NOT USE THE KEYBOARD OR MOUSE, AS IT MAY DISTURB THE SCRIPT THAT WILL INSTALL THE PROGRAM. A normal installation wizard then runs, except the developers are not trusted to click the buttons, and instead the script does it for you by moving and clicking the mouse.
All of this is documented. In markdown like reasonable people? Of course not! It is in ENHANCED markdown. Which is markdown in the same way javascript is java.
ENHANCED markdown requires browser and visual studio code extensions to be read. Completely missing the point of markdown being readable both raw and encoded… And sometimes word documents And sometimes power-point presentations left next to another bat file… this one calling the .exe file… right next to it…. I later found out is because the idea USED to be that all documentation MUST be made with Microsoft office tools.
I had to read the code of conduct today. And it was actually very well written.
I then watched a interactive animation telling me about the code of conduct… which it not only got a fact wrong about, it also broke it once.
I repeat. The introductory course in the code of conduct… broke the code of conduct'
After I watched that, and read the safety material…. which literally just said "Wear safety boots in the production floor"… I was then show the testing room.
I was lead to a different building, saying hello to the Vice CEO who was walking the other way, we walk into the production floor, ignored the fact that none of us have safety boots on, and walks into a room, with a 3*2 meter wide machine, several meters tall.
We edge around it, quietly hoping no one turns it on, since we would get slammed by it if they did, and walk down some stairs into the basement. Casually walk over a small river in the floor from a pipe that is leaking… what I really hope is water, and over to a shelf rack FILLED with the most MacGyver shit you ever did see.
Including, but not limited to, the 3D printed plastic block, with a piston that repeatedly smacking half a aluminum nameplate over the device it is testing. You see, it is a capacitance button, and it is testing it by simulating a human finger pressing it many thousands of times, a saws off antenna which is the end of a cable that is attached to it via a nice thick bolt, so it can send fake signals into it.
And of course the 24 volt, 5 amp system that is turning a circuit board on and off again, until it will crack.
We walk back out, remembering to step over the small river, which never even got a comment, and walk back to my department It is SO great. It is like working in the ministry of silly walks by Monty Python Like… Do I think I can bring value to this company? Like, making it better and more efficient? Yes. It would be hard not to!
And his is the largest pump manufacturer in the world! A super serious company with 4 billion dollars of revenue a year. And it is just… a NUTHOUSE
Like… NEVER believe the myth that corporations are competent.

AOSP Architecture Explained: A Practical Guide for Android Developers
In this blog, we delve into the architecture of the Android Open Source Project (AOSP), breaking down each layer of the software stack. From the Linux Kernel to Applications, we explore the functionalities and responsibilities of each component. Whether you're customizing ROMs or developing hardware-specific solutions, understanding the AOSP architecture is crucial.
The Android Open Source Project (AOSP) serves as the foundation for the Android operating system, offering a comprehensive software stack that enables developers to create a consistent user experience across various devices. Understanding the AOSP architecture is essential for developers aiming to build custom Android builds or integrate deeply with system components.
Overview of the AOSP Software Stack
The AOSP software stack is organized into several layers, each responsible for specific functionalities:
Linux Kernel: At the base, the Linux Kernel manages core system services such as process management, memory management, and hardware drivers. It acts as an abstraction layer between the hardware and the rest of the software stack.
Hardware Abstraction Layer (HAL): HAL provides standard interfaces that expose device hardware capabilities to the higher-level Java API framework. This allows Android to be agnostic about lower-level driver implementations.
System Services and Daemons: These are background processes that provide core system functionalities like power management, telephony, and media playback. They facilitate communication between the HAL and the Android Runtime.
Android Runtime (ART): ART is the managed runtime used by applications and some system services. It includes a set of core libraries and handles tasks like memory management, garbage collection, and bytecode execution.
System APIs: These APIs provide the necessary interfaces for applications to interact with the underlying hardware and system services, enabling functionalities like location services, telephony, and sensor management.
Android Framework: The framework offers a rich set of APIs that developers use to build applications. It includes components like Activity Manager, Window Manager, and Content Providers, which manage the user interface and application resources.
Applications: At the top layer, applications include both native apps provided by the device manufacturer and third-party apps installed by users. These apps interact with the Android Framework to perform their functions.
Importance for Developers
Understanding the AOSP architecture is vital for several reasons:
Customization: For developers building custom ROMs or tailoring Android for specific hardware, knowledge of each layer allows for effective customization and optimization.
Performance Optimization: Identifying and addressing performance bottlenecks requires a deep understanding of how different layers interact and where potential issues may arise.
Scalability: Proper utilization of the Android Framework and System APIs ensures that applications are scalable and maintain compatibility across various devices and Android versions.
Security: Awareness of the interactions between privileged and system-level components is crucial for developing secure applications and protecting user data.
Conclusion
The AOSP software stack is a meticulously designed architecture that harmonizes hardware and software components to deliver a seamless user experience. For developers, mastering this architecture is key to unlocking the full potential of Android, whether it's for application development, system customization, or hardware integration.

Difference Between Java and JavaScript
When it comes to programming, Java and JavaScript are two of the most widely used languages. Despite their similar names, they are quite different in terms of functionality, usage, and even underlying principles. This often leads to confusion among beginners who may assume that the two technologies are related. However, understanding the differences between Java and JavaScript can give developers the clarity they need to decide which tool is best suited for their specific needs.
In this blog, we will explore the key differences between Java and JavaScript by discussing their features, syntax, platforms, and use cases. By the end, you will have a clearer understanding of when and why to use each of these languages.
1. What is Java?
Java is a powerful, object-oriented programming (OOP) language developed by Sun Microsystems (now owned by Oracle). It was first released in 1995 and is designed to be a platform-independent language that allows developers to "write once, run anywhere." This means that Java code can be written on one platform (e.g., Windows, macOS, Linux) and run on any device that has a Java Virtual Machine (JVM) installed. The JVM translates the compiled Java bytecode into machine-specific code, making it platform-independent.
Java is primarily used for developing standalone applications, large enterprise systems, Android applications, and server-side applications. It’s known for its stability, scalability, and performance.
2. What is JavaScript?
JavaScript, on the other hand, is a lightweight, interpreted scripting language that was created for web development. Originally designed to run in web browsers, it allows developers to create dynamic and interactive elements on websites. JavaScript was created by Brendan Eich at Netscape Communications in 1995 and has since evolved into one of the most important languages in web development.
JavaScript is a client-side language, which means it runs in the browser, but it can also be used on the server side through Node.js. Unlike Java, JavaScript is not a strictly object-oriented language; it supports multiple programming paradigms such as procedural, functional, and event-driven programming.
3. Syntax Differences Between Java and JavaScript
One of the most noticeable differences between Java and JavaScript lies in their syntax. While they may share some similar constructs (like curly braces for code blocks), the syntax rules and programming paradigms they follow are quite different.
Java is a statically-typed language, meaning that you must declare the type of variable before using it. For example:javaCopyint number = 10; String message = "Hello, World!"; The types (like int and String) must be specified and can’t be changed once the variable is declared.
JavaScript, on the other hand, is dynamically typed. This means you do not have to specify the type of the variable before using it, and the type can change as the program runs. For example:javascriptCopylet number = 10; let message = "Hello, World!"; Here, the type of number and message is determined dynamically at runtime.
4. Compiling vs. Interpreting
Another significant difference between Java and JavaScript is how they are executed.
Java is a compiled language. This means that Java code is first written and then compiled into bytecode by a Java compiler. The bytecode is platform-independent and can be run on any device that has a Java Virtual Machine (JVM). This provides portability and allows Java applications to run across different systems without modification.Steps in Java Execution:
Write Java source code (.java file).
Compile the code using a Java compiler, which converts it into bytecode (.class file).
The bytecode is then executed by the JVM.
JavaScript, on the other hand, is an interpreted language, which means the code is executed line-by-line by an interpreter (usually within a web browser). The JavaScript engine in a browser reads the JavaScript code, interprets it, and executes it in real-time.Steps in JavaScript Execution:
Write JavaScript code (.js file).
The code is directly interpreted and executed by a web browser or JavaScript runtime environment like Node.js.
5. Execution Environment
Java and JavaScript also differ greatly in terms of their execution environments:
Java is typically used for building standalone applications that run on the JVM. These applications can be anything from mobile apps (Android) to large-scale enterprise applications or even desktop software.
JavaScript, on the other hand, is designed for web development. It is mostly used to create dynamic web pages, handle user interactions, and perform client-side tasks. JavaScript code runs within a web browser (Chrome, Firefox, Safari, etc.) and can also run on the server side through Node.js.
6. Object-Oriented vs. Multi-Paradigm
Java is primarily an object-oriented programming (OOP) language, which means it is based on the principles of encapsulation, inheritance, and polymorphism. Java focuses heavily on classes and objects, and most Java programs are organized around these core concepts.
JavaScript, however, is a multi-paradigm language. While it can support object-oriented programming (OOP) through prototypes, it also supports functional programming and event-driven programming. JavaScript uses prototypes for inheritance rather than classes (though modern JavaScript has introduced classes, they are syntactic sugar over prototypes).
7. Memory Management
Both Java and JavaScript have automatic memory management, but they handle it differently:
Java uses garbage collection to automatically manage memory. The JVM’s garbage collector automatically frees up memory that is no longer in use. Java also allows developers to manually control memory management through various memory allocation techniques.
JavaScript also uses garbage collection for memory management, but since JavaScript runs in a single-threaded environment (in the browser), memory management is typically more lightweight and less complex compared to Java.
8. Use Cases
The primary use cases for each language highlight their distinct roles in the software development landscape.
Java:
Enterprise Applications: Java is often used in large-scale business systems due to its scalability, robustness, and extensive libraries.
Mobile Development: Java is the official language for Android app development.
Backend Systems: Java powers many server-side applications, particularly in environments that require high performance.
Embedded Systems: Java is used in various embedded systems due to its portability and efficiency.
JavaScript:
Web Development: JavaScript is essential for front-end web development, enabling dynamic and interactive web pages.
Backend Development: With the rise of Node.js, JavaScript can also be used on the server side to build web servers and APIs.
Mobile Apps: JavaScript frameworks like React Native and Ionic allow developers to create mobile applications for both iOS and Android.
Game Development: JavaScript is increasingly used in building browser-based games or game engines like Phaser.js.
9. Performance
Performance is another area where Java and JavaScript differ significantly.
Java generally performs better in comparison to JavaScript because it is a compiled language. The compiled bytecode is optimized by the JVM and can be executed more efficiently. Java is well-suited for large-scale applications that require high performance.
JavaScript is typically slower than Java due to its interpreted nature and the overhead involved in real-time interpretation. However, JavaScript has made significant strides in performance, especially with modern engines like V8 (used in Google Chrome and Node.js), which optimize execution.
10. Learning Curve
Java can be more difficult to learn for beginners because it’s a statically-typed language with a focus on OOP principles. The syntax and structure are more complex, and it requires understanding various programming concepts such as classes, interfaces, and inheritance.
JavaScript is often considered easier to learn, especially for web developers, because it is dynamically typed and has a simpler syntax. Additionally, JavaScript is very forgiving with variable types, making it easier to experiment with code.
Conclusion
While Java and JavaScript have similar names, they are fundamentally different languages with different uses, execution models, and ecosystems. Java is a versatile, platform-independent, and high-performance language primarily used for backend applications, mobile development, and large-scale enterprise solutions. JavaScript, on the other hand, is a lightweight, interpreted language that powers the dynamic, interactive elements of the web.
Choosing between Java and JavaScript depends on the specific needs of your project. If you are working on a web-based application or interactive front-end elements, JavaScript will be the way to go. If you are building complex back-end systems, enterprise software, or mobile apps, Java might be more appropriate. Both languages are crucial in their own domains, and mastering them can open up a world of development opportunities.

What is encapsulation in Python? - Encapsulation is the concept of restricting access to certain parts of an object, typically the internal data. In Python, encapsulation is achieved using private variables and methods.
What is polymorphism in Python? - Polymorphism is the ability of an object to take on different forms or behaviors simplicity and readability.
How do you comment in Python? - Comments in Python start with a hash (#) symbol and continue until the end of the line.
What are the basic data types in Python? - Python has several basic data types, including integers, floats, strings, booleans, and NoneType.
How do you define a variable in Python? - Variables in Python are defined using the assignment operator (=).
What is a tuple in Python? - A tuple is an immutable collection of elements, typically used to store related data.
Data Structures
What is a list in Python? - A list is a mutable collection of elements, enclosed in square brackets ([]), and can contain elements of different data types.
How do you access elements in a list? - Elements in a list can be accessed using their index, starting from 0.
What is a dictionary in Python? - A dictionary is a collection of key-value pairs, enclosed in curly braces ({}), and is mutable.
How do you iterate over a dictionary in Python? - You can iterate over a dictionary using a for loop, accessing the keys or values of each key-value pair.
What is a set in Python? - A set is an unordered collection of unique elements, enclosed in curly braces ({}).
Control Flow
What are the different types of loops in Python? - Python supports for loops and while loops for iteration.
How do you use conditional statements in Python? - Python uses if, elif, and else keywords for conditional statements.
What is the difference between break and continue statements? - The break statement terminates the loop, while the continue statement skips the current iteration and continues with the next iteration.
Functions and Modules
What is a function in Python? - A function is a block of reusable code that performs a specific task.
How do you define a function in Python? - Functions in Python are defined using the def keyword, followed by the function name and parameters.
