This guide walks you through installing custom Linux images in WSL 2, giving you complete control over your Linux environment on Windows. Many users encounter conflicts when running both WSL and Docker Desktop on the same system. Docker Desktop frequently reconfigures WSL settings during installation, sometimes causing unexpected changes to your WSL distribution setup. Additionally, the Microsoft Store doesn't allow installing multiple instances of the same distribution version (though you can work around this through export/import operations). This guide presents a practical, tested approach to installing custom Linux distributions in WSL 2, based on real-world experience rather than theoretical documentation. Enabling WSL 2 Before installing a custom Linux distribution, you need to ensure WSL 2 is properly enabled on your Windows system: Method 1: Quick Installation (Windows 10 version 2004 and higher or Windows 11) Open PowerShell or Command Prompt as Administrator and run: wsl --install This command installs everything needed, including the Virtual Machine Platform and a default Ubuntu distribution. If you only want to enable the WSL infrastructure without installing a... --- ### Running macOS on Ubuntu 24.04 with QEMU/KVM Virtualization - Published: 2025-03-28 - Modified: 2025-03-28 - URL: https://betelgeuse.work/macos-qemu/ - Categories: education Running macOS on Ubuntu 24. 04 Desktop: A Comprehensive Guide Introduction and Hardware Requirements If you've ever wanted to experience macOS without purchasing Apple hardware, virtualization offers an excellent alternative. This guide walks you through setting up macOS on Ubuntu 24. 04 using QEMU/KVM virtualization. We'll be following the well-maintained OSX-KVM GitHub project as our reference. Checking Hardware Compatibility Before beginning, it's essential to verify that your system supports hardware virtualization, which significantly improves performance. Your CPU must support either Intel VT-x or AMD SVM technology. In our test environment, we're using: Intel Core i7-7700HQ (8 cores) To check if your system supports virtualization, run the following command: grep -e vmx -e svm /proc/cpuinfo If your output contains "vmx" (for Intel processors) or "svm" (for AMD processors), hardware virtualization is enabled on your system. If these flags don't appear, you'll need to: Enter your BIOS/UEFI settings (typically by pressing F2, Delete, or F12 during boot) Look for options related to "Virtualization Technology," "Intel VT-x," "AMD-V," or "SVM Mode" Enable these settings Save changes and reboot your computer Hardware virtualization provides several significant benefits: Dramatically improved performance: Virtual machines run much faster with direct hardware access Reduced overhead: Less resource consumption compared to software-only virtualization Advanced features: Support for nested virtualization and enhanced security options Installing QEMU and Required Dependencies Now that we've confirmed hardware virtualization support, let's install QEMU (Quick EMUlator), which will serve as our virtualization platform. First, let's try installing QEMU with the basic command: sudo apt install qemu However,... --- ### DHCP and PXE Server Configuration Using Docker Containers - Published: 2025-03-27 - Modified: 2025-03-27 - URL: https://betelgeuse.work/dhcp-pxe-server/ - Categories: education Configuring a DHCP server is very useful to streamline network management and eliminate the need for manual IP address configuration. Furthermore, it is also an essential element in building a PXE server for network booting. This article details how to set up a DHCP server and a PXE server to create a seamless network environment. What is DHCP? DHCP (Dynamic Host Configuration Protocol) is a mechanism for automatically assigning IP addresses to devices in a network. It eliminates the need to manually set up IP addresses. Example: For example, when you connect your phone to your home Wi-Fi, the DHCP server automatically assigns an IP address to your phone. This allows your phone to connect to the Internet. Why is this important? Simplicity: When you add a new device to your network, you do not have to manually set its IP address. Efficiency: Prevents duplicate IP addresses and simplifies network management. Flexibility: When a device leaves the network and reconnects, it can be assigned a different IP address. The first step is to install a DHCP server to automatically assign IP addresses. This way, devices in the network are centrally managed and configuration is simplified. We will then move on to how to set up a PXE server and establish a network boot mechanism. Before starting work, check your current network environment and IP address status. If you check it first, you will be able to clearly see the changes after the configuration. since we want to achieve this using... --- ### Case Study: Home Network Segmentation and NAT Configuration - Published: 2025-03-27 - Modified: 2025-03-28 - URL: https://betelgeuse.work/ip-forwarding-nat/ - Categories: education In my current home network environment, my router connects all devices to the Internet. Here is the current situation and the planned configuration. 1. Current situation with discretionary router Current home network configuration In most homes, Internet access is provided by a single router. This router is provided by the Internet provider and performs the following functions Providing Internet connectivity: The router connects to the Internet and makes the Internet available throughout the home. Providing a WiFi network: The router sends out a WiFi signal to which smartphones, tablets, laptops, etc. connect. Functioning as a DHCP server: The router assigns an IP address to each device. Home Network Configuration (Internet) | | So we decided to separate the networks. We had separated them before, but it was too much trouble and we did not do it. We decided to take this opportunity to review our settings. Most laptops have wifi and wired physical networks, so we will use these.

The main purpose of using a python virtual environment ( such asvenv or virtualenv ) is to avoid "messing up" the host environment. Using virtual environments provides the following advantages Environment isolation: Virtual environments provide a separate Python environment for each project or task. This allows different projects with different library versions to work without interfering with each other. Protection of the host environment: Allows you to manage dependencies on a per-project basis without having to change the system-wide Python environment or libraries. This prevents the system's Python environment from becoming "dirty. Avoiding Version Issues: If a particular project requires an older version of a library, or if a newer version of a library is to be tested, the virtual environment makes it easy to install and manage those versions. Portability and reproducibility: Exporting dependencies of the virtual environment using requirements. txt makes it easy to share and reproduce the environment with other machines and team members. Thus, with proper use of the virtual environment, project dependencies can be managed without cluttering up the host environment. https://github. com/FurkanGozukara/Stable-Diffusion/blob/main/Tutorials/AI-Music-Generation-Audiocraft-Tutorial. md The version of Python is also important.

In particular, if the embedded links and image URLs in the site continue to reference the old domain, certain parts of the site may not display correctly. For example, the following issues commonly occur: Images not displaying: Images inserted in posts or pages may stop appearing because they still use the old domain name. If the image links are not correctly updated, visitors will encounter "Image not found" errors. Links not functioning: Internal and external links within the site may still reference the old domain, preventing users from navigating to the intended pages when clicked. This harms the user experience and negatively impacts SEO (Search Engine Optimization). Unable to access the admin dashboard: If the WordPress admin dashboard is still operating based on the old domain, it may become inaccessible after migration. This issue can prevent you from making site settings or editing content, disrupting site management. Themes and plugins not functioning properly: Some themes and plugins may have hardcoded URLs. If these settings are not updated, the themes and plugins may not function as expected. These issues cannot be solved merely by moving the WordPress files because WordPress stores URLs in the database, and these must be properly updated. However, manually updating the database is time-consuming and prone to errors. To address these issues efficiently, a more streamlined approach is required.

This isn’t a bug—it’s a quirk of how WSL manages its virtual storage. In this article, we delve into why disk space seems “stuck” even after file removal, and we introduce an automated solution designed to simplify reclaiming that lost space. https://youtu. be/Gn4Pr03HtIo Uncovering the Hidden Mechanics Behind WSL’s Phantom Disk Space When you delete large files within your WSL environment, you might expect an immediate reduction in your Windows disk usage. However, the reality is more nuanced. Let’s break down the underlying factors: 1. Virtual Disk Characteristics WSL2 leverages a dynamically allocated virtual disk file (typically named ext4. vhdx) to store the Linux filesystem. Here’s what you need to know: Expansion Without Automatic Contraction:The VHDX file expands as you add data, but—by design—it does not shrink automatically when you delete files. Perceived vs. Actual Free Space:Within the Linux environment, the filesystem reports the freed space correctly. In contrast, Windows continues to see the unchanged size of the VHDX file. To illustrate, consider the following table: AspectBehaviorExpansionIncreases as more data is storedContractionDoes not reduce automatically after file deletionWindows PerspectiveContinues to show the full allocated size of the VHDX, regardless of internal deletionsLinux PerspectiveAccurately reflects the freed space within its own filesystem 2.

It’s a common puzzle: where does that deleted space actually go? In this article, we’ll explore why freed space isn’t immediately reflected in Windows, explain how WSL 1 and WSL 2 handle storage differently, and introduce practical steps to reclaim disk space on your host machine. Why Deleting Files in WSL Doesn’t Always Reduce Windows Disk Usage Windows Subsystem for Linux (WSL) runs a Linux environment on top of the Windows filesystem. Depending on your version of WSL: WSL 1 integrates Linux calls into the Windows NT kernel, meaning it works more like a compatibility layer. WSL 2 uses an actual Linux kernel inside a virtual machine (VM), storing data in a special virtual hard disk file (VHD or VHDX). The key point? Deleting files inside WSL doesn’t always translate into immediate space savings on the Windows side. That’s because the underlying virtual disk (in WSL 2) or filesystem integration (in WSL 1) might not release space back to the host OS right away. WSL 2 in Focus In WSL 2, your Linux environment runs in a lightweight VM, and files reside within a VHD(X) file. Even if you remove massive directories—like Docker images or large AI model repositories—Windows still sees the VHD file at the same size. Why? Because the virtual... --- ### Why FFmpeg Matters: Installing on Windows and WSL - Published: 2025-01-29 - Modified: 2025-03-24 - URL: https://betelgeuse.work/ffmpeg-install/ - Categories: education Introduction: Why FFmpeg Matters in the Age of AI Music Many websites explain how to install FFmpeg, but very few really dig into why you need it.

While this accessibility is a huge advantage, running applications securely has never been more important. One indispensable tool in achieving a secure environment is the reverse proxy. What Is a Reverse Proxy? graph LR U((User)) RP A U -->|HTTPS| RP RP -->|HTTP| A style U fill:#f9f,stroke:#333,stroke-width:2px style RP fill:#90EE90,stroke:#333,stroke-width:2px style A fill:#87CEEB,stroke:#333,stroke-width:2px %% Annotations for explanation subgraph Internet U end subgraph Internal Network RP A end Think of a reverse proxy as a gatekeeper that stands between your end users and the actual web application. Here’s a simplified scenario: When a user tries to access your site, the reverse proxy is the first point of contact. The proxy can detect suspicious traffic or malicious requests, blocking them before they ever reach the application server. It also manages secure communication by encrypting traffic (HTTPS), which helps protect sensitive data from eavesdropping. By inserting this “gatekeeper” in front of your application servers, you can significantly reduce security risks and centralize the management of incoming traffic. Why Do You Need a Reverse Proxy? 1. Enhanced Security Shielding the App ServerYour application server won’t be directly exposed to the public Internet, limiting potential attack vectors. Blocking Malicious RequestsSuspicious IP addresses or harmful requests can be filtered out. Encrypted CommunicationHTTPS ensures that data in transit is encrypted, protecting it from interception. 2.

Although it was created for the Japanese stock market, the same dreary approach can be applied to a variety of market data around the world. You can grudgingly check major indices, individual stock prices, price fluctuation rates, and sector data all at once, with a half-decent sector-based filtering feature and a bare-bones stock search function thrown in. Global Applicability Despite the hassle, the fundamental design of this system can be shoved into all sorts of market data scenarios, such as: Stock market data from different countries Commodity futures market prices Foreign exchange rates Cryptocurrency price data The bottom line is that, as long as you can manage to secure a data source, the architecture here can be repurposed for pretty much any market. By combining it with the APIs or tools offered by local securities firms or data providers in your region, you could scrape together a similar system—assuming you really want to. System’s Basic Mechanism It’s essentially a hastily slapped-together setup that grabs market data from some source (like Excel or an API), funnels it through a web server, and dumps it in your browser. Whenever the data source decides to update, the browser grudgingly refreshes so you can witness the latest numbers—assuming that matters to you.

Before we begin, we will explain the differences between a Python virtual environment and Docker. You cannot install CUDA directly within a Python virtual environment (venv); CUDA is a system-level component and must be installed on the host system. The Python virtual environment is used to isolate Python packages and their dependencies, but it cannot be used to install or manage system-level software or drivers such as CUDA. To use CUDA, the following steps must be taken: Install CUDA on the host system: Follow the CUDA Toolkit Installation Guide to install CUDA on the host system. After installation, you will be able to access the CUDA Toolkit and its dependencies by setting the environment variables appropriately. Create a Python Virtual Environment: Create a Python virtual environment on the host system where CUDA is installed. Install CUDA-supporting packages in the virtual environment: Install Python packages that utilize CUDA (e. g. , TensorFlow, PyTorch, etc. ) within the virtual environment. Verify that CUDA is functioning properly: Use a Python script or notebook to verify that CUDA is working properly. This step can be performed using the test scripts provided in the official documentation of the specific deep learning framework. Once this process is complete, CUDA can be used from within the virtual environment. Docker uses WSL 2 as its backend, and containers running on a Linux distribution have access to that distribution’s resources and functionality... . ---
