By default, it offers various themes to personalize your terminal. But what if you want your terminal to dynamically change its theme based on the environment or directory you\u0026rsquo;re working in? This post will guide you through a script that achieves just that.\nThe Script: Dynamic Theme Switching The following script dynamically updates the Oh My Bash theme based on your current environment and directory. Here\u0026rsquo;s the code:\nthemes_function() { local new_theme=\u0026#34;\u0026#34; case \u0026#34;$env:$PWD\u0026#34; in devbox:*) new_theme=\u0026#34;devbox\u0026#34; ;; *:/home/jose/gitlab/personal/*|*:/home/jose/gitlab/personal) new_theme=\u0026#34;jose\u0026#34; ;; *:/home/jose/gitlab/customer/*|*:/home/jose/gitlab/customer) new_theme=\u0026#34;customer\u0026#34; ;; *) new_theme=\u0026#34;bakkex\u0026#34; # Default theme ;; esac # Only change the theme if it\u0026#39;s different from the current theme if [[ \u0026#34;$new_theme\u0026#34; != \u0026#34;$CURRENT_OSH_THEME\u0026#34; ]]; then CURRENT_OSH_THEME=\u0026#34;$new_theme\u0026#34; export OSH_THEME=\u0026#34;$CURRENT_OSH_THEME\u0026#34; source \u0026#34;$OSH\u0026#34;/oh-my-bash.sh fi } # Add the function to PROMPT_COMMAND PROMPT_COMMAND=\u0026#34;themes_function; $PROMPT_COMMAND\u0026#34; How It Works Environment and Directory Matching:\nThe script uses a case statement to match combinations of the environment variable env and the current working directory (PWD). Depending on the match, it assigns a specific theme to the new_theme variable. Theme Switching:\nIf the selected theme is different from the current theme (CURRENT_OSH_THEME), the script updates the theme by: Setting the CURRENT_OSH_THEME and OSH_THEME variables. Re-sourcing the Oh My Bash script (oh-my-bash.sh) to apply the new theme. Automatic Execution:\nThe themes_function is added to the PROMPT_COMMAND variable, ensuring it runs every time the terminal prompt is displayed. Customizing the Script Environment Variable env: Ensure the env variable reflects your actual terminal environment. If it\u0026rsquo;s not set, you can modify the script to use another variable or remove it entirely.\nTheme Names: Replace devbox, jose, allianz, and bakkex with your preferred Oh My Bash themes. Make sure these themes are installed and available in your setup.\nDirectory Paths: Update the paths in the case statement to match the directories relevant to your workflow.\nApplying the Script Add the script to your .bashrc or .bash_profile file:\nnano ~/.bashrc Save the file and reload your shell configuration:\nsource ~/.bashrc Test the script by navigating to different directories and observing the theme changes.\nConclusion With this script, you can add a dynamic and context-aware touch to your terminal setup. Oh My Bash\u0026rsquo;s flexibility combined with Bash scripting allows for powerful customizations tailored to your needs.

By following these steps, you can customize and personalize your themes and PS1 prompt to create a more enjoyable and productive shell experience.\nStep 1: Install Oh-My-Bash First, you need to install Oh-My-Bash. You can do this by running the following command in your terminal:\nsh -c \u0026#34;$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)\u0026#34; Step 2: Configure Your Shell Next, insert the following script into your ~/.bashrc file to set your preferred theme. You can replace \u0026quot;bakke\u0026quot; with any theme you like:\nif [ -z \u0026#34;$OSH_THEME\u0026#34; ]; then OSH_THEME=\u0026#34;bakke\u0026#34; # choose the theme you like source ~/.bashrc fi Step 3: Update Your Devbox Configuration Now, from your Devbox project, open the devbox.json file and add the shell initialization hook to ensure your theme and configurations are applied when you start a Devbox shell:\n{ \u0026#34;$schema\u0026#34;: \u0026#34;https://raw.githubusercontent.com/jetify-com/devbox/0.12.0/.schema/devbox.schema.json\u0026#34;, \u0026#34;packages\u0026#34;: [\u0026#34;wails@latest\u0026#34;], \u0026#34;shell\u0026#34;: { \u0026#34;init_hook\u0026#34;: [ \u0026#34;echo \u0026#39;Welcome to devbox!\u0026#39; \u0026gt; /dev/null\u0026#34;, \u0026#34;OSH_THEME=purity\u0026#34;, \u0026#34;source ~/.bashrc\u0026#34; ], \u0026#34;scripts\u0026#34;: { \u0026#34;test\u0026#34;: [\u0026#34;echo \\\u0026#34;Error: no test specified\\\u0026#34; \u0026amp;\u0026amp; exit 1\u0026#34;] } } } In this example, the OSH_THEME is set to \u0026quot;purity\u0026quot;, but you can choose any other theme you prefer.\nStep 4: Personalize Your PS1 Prompt To customize your PS1 prompt, edit the theme\u0026rsquo;s theme.sh file. For instance, if you are using the purity theme, the file path would be ~/.oh-my-bash/themes/purity/purity.theme.sh.\nOpen the file and edit the PS1 variable with your desired style. Here\u0026rsquo;s an example:\nPS1=\u0026#34;\\n📦${_omb_prompt_bold_purple} Devbox: ${_omb_prompt_navy}\\w $(scm_prompt_info)\\n${ret_status} \u0026#34; Save your changes after editing.\nStep 5: Apply Your Changes Finally, load your changes by sourcing your ~/.bashrc file:\nsource ~/.bashrc Result After completing these steps, your shell should look something like this when you enter a Devbox shell:\nfedora: ~/gitlab/coco |main ✓| → devbox shell Starting a devbox shell... 📦 Devbox: ~/gitlab/coco ( main ✓ ) ❯ exit exit fedora: ~/gitlab/coco |main ✓| → With these configurations, you can enjoy a customized and productive shell environment within Jetify Devbox using Oh-My-Bash.

define a function to specify the allowed origins for CORS. This function also logs disallowed origins:\nfunc AllowOriginFunc(r *http.Request, origin string) bool { allowedOrigins := []string{\u0026#34;http://localhost\u0026#34;, \u0026#34;https://admin-micro-qa.clorian.com\u0026#34;} for _, o := range allowedOrigins { if origin == o { return true } } // Get the client\u0026#39;s IP address clientIP := r.RemoteAddr // Print the log in red color red := \u0026#34;\\033[31m\u0026#34; reset := \u0026#34;\\033[0m\u0026#34; log.Printf(\u0026#34;%sDisallowed origin: %s, Client IP: %s%s\u0026#34;, red, origin, clientIP, reset) return false } In this function:\nallowedOrigins: This slice contains the origins that are permitted to access the resources. Loop through allowed origins: The function checks if the request origin is in the list of allowed origins. Logging disallowed origins: If the origin is not allowed, the function logs this event using log.Printf. Explanation of log.Printf log.Printf is a function from the Go log package that formats according to a format specifier and writes to the standard logger.\nIn this code:\nred and reset are ANSI escape codes for coloring the output in the terminal. \\033[31m sets the text color to red, and \\033[0m resets it to the default color. log.Printf prints a formatted string that includes the disallowed origin and the client\u0026rsquo;s IP address in red color to emphasize that it is a disallowed request. The formatted string includes placeholders (%s) which are replaced by the specified variables (origin and clientIP). Step 3: Initialize the Router Now we initialize the router, configure middleware, and set up CORS:\nfunc Init(db *gorm.DB) *chi.Mux { r := chi.NewRouter() r.Use(middleware.Logger) sm := services.NewServiceManager(db) r.Use(cors.Handler(cors.Options{ AllowOriginFunc: AllowOriginFunc, AllowedMethods: []string{\u0026#34;GET\u0026#34;, \u0026#34;POST\u0026#34;, \u0026#34;PUT\u0026#34;, \u0026#34;DELETE\u0026#34;, \u0026#34;OPTIONS\u0026#34;}, AllowedHeaders: []string{\u0026#34;Accept\u0026#34;, \u0026#34;Authorization\u0026#34;, \u0026#34;Content-Type\u0026#34;, \u0026#34;X-CSRF-Token\u0026#34;}, ExposedHeaders: []string{\u0026#34;Link\u0026#34;}, AllowCredentials: true, MaxAge: 300, })) r.HandleFunc(\u0026#34;/health\u0026#34;, func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, \u0026#34;Hello, Go!\u0026#34;) }) return r } Setting Up the Health Check Endpoint The health check endpoint is a simple route that responds with a message indicating the service is running:\nr.HandleFunc(\u0026#34;/health\u0026#34;, func(w http.ResponseWriter, r *http.Request) { fmt.Fprint(w, \u0026#34;Hello, Go!\u0026#34;) }) Putting It All Together

In this case, you can call an API trigger from one project to another (this is just a example).\nI\u0026rsquo;ve been in the situation described above before, and it was how I discovered this amazing feature in GitLab.\nLet\u0026rsquo;s identify our projects:\n* Project Caller: This will be the project that calls the trigger API. * Project Triggering: This is the project where the remote pipeline is located. From the Triggering Project, you need to activate the triggering token. To do this, go to \u0026ldquo;CI/CD Settings - Pipeline Trigger Tokens.\u0026rdquo;\nThen, use the generated token and add it as a variable in the \u0026ldquo;CI/CD Settings\u0026rdquo; of your Project Caller.\nNow, you can activate the trigger from the Project Caller to the Project Triggering. You can use the following example as a pipeline.

One of the recommended approaches is to utilize virtual environments. Virtual environments allow you to create an isolated environment for each project, preventing conflicts between different packages and dependencies. In this guide, we\u0026rsquo;ll walk you through the steps to set up and activate a virtual environment for your Python 3 project.\nStep 1: Install python3-venv First, make sure you have the python3-venv package installed on your Linux system. This package provides the necessary tools to create and manage virtual environments. Open a terminal and run the following command:\nNote: venv (for Python 3) and virtualenv (for Python 2)\nsudo apt-get install python3-venv Step 2: Create a New Virtual Environment Navigate to the directory where you want to create your project and virtual environment. Once there, run the following command to create a new virtual environment named myenv:\npython3 -m venv myenv Step 3: Activate the Virtual Environment To start working within the virtual environment, you need to activate it. Use the following command to activate the myenv environment:\nsource myenv/bin/activate Once activated, you\u0026rsquo;ll notice that your command prompt changes to reflect the name of the active environment (myenv in this case). From now on, any Python packages you install or scripts you run will be isolated within this environment.\nStep 4: Install Project Dependencies With the virtual environment active, you can now install the necessary Python packages for your project. It\u0026rsquo;s recommended to use a requirements file to manage your dependencies. Create a file called requirements.txt in your project directory and add the required packages with their versions, each on a separate line. For example:\nnumpy==1.20.3 pandas==1.3.0 To install these dependencies, run the following command:\npip install -r requirements.txt Now that your virtual environment is set up and dependencies are installed, you\u0026rsquo;re ready to start developing your Python 3 project!\nHow to deactivate the Virtual Environment Once you\u0026rsquo;re done working on your project, it\u0026rsquo;s good practice to deactivate the virtual environment. To do this, simply run the following command:\ndeactivate Further info go to official page here\n","permalink":"https://jose.castrillo.eu/post/python3-environment/","summary":"\u003cp\u003e\u003cimg loading=\"lazy\" src=\"https://castrillo.gitlab.io/figaro/python-env.jpg\" alt=\"\"  /\u003e\n\u003c/p\u003e\n\u003cp\u003eWhen starting a Python 3 project in Linux, it\u0026rsquo;s essential to follow best practices to ensure a clean and isolated development environment.

The abbreviation stands for Redundant Array of Inexpensive Disks. A RAID system consists of two or more drives working in parallel. These disks can be hard discs, but there is a trend to also use the technology for SSD (solid state drives). There are different RAID levels, each optimized for a specific situation. These are not standardized by an industry group or standardization committee.\nStriping - RAID 0 In a RAID 0 system data are split up into blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, this offers superior I/O performance. This performance can be enhanced further by using multiple controllers, ideally one controller per disk. Mirroring - RAID 1 Data are stored twice by writing them to both the data drive (or set of data drives) and a mirror drive (or set of drives). If a drive fails, the controller uses either the data drive or the mirror drive for data recovery and continues operation. RAID 5 This level is based on block-level striping with parity. The parity information is striped across each drive, allowing the array to function even if one drive were to fail. The array\u0026rsquo;s architecture allows read and write operations to span multiple drives. This results in performance that is usually better than that of a single drive, but not as high as that of a RAID 0 array. RAID 5 requires at least three disks, but it is often recommended to use at least five disks for performance reasons.\nRAID 6 RAID 6 is like RAID 5, but the parity data are written to two drives. That means it requires at least 4 drives and can withstand 2 drives dying simultaneously. The chances that two drives break down at exactly the same moment are of course very small. However, if a drive in a RAID 5 systems dies and is replaced by a new drive, it takes hours or even more than a day to rebuild the swapped drive. If another drive dies during that time, you still lose all of your data. With RAID 6, the RAID array will even survive that second failure.\nRAID 10 (RAID 1+0): Combining RAID 1 and RAID 0, this level is often referred to as RAID 10, which offers higher performance than RAID 1, but at a much higher cost. In RAID 1+0, the data is mirrored and the mirrors are striped. These levels do exist but are not that common (RAID 3 is essentially like RAID 5 but with the parity data always written to the same drive). This is just a simple introduction to RAID-systems.\n","permalink":"https://jose.castrillo.eu/post/raid-disk/","summary":"\u003ch1 id=\"raid\"\u003eRAID\u003c/h1\u003e\n\u003cp\u003eRAID is a technology that is used to increase the performance and/or reliability of data storage. The abbreviation stands for Redundant Array of Inexpensive Disks. A RAID system consists of two or more drives working in parallel.
