Where does ubuntu save its X configuration files ?

In newer versions of Ubuntu, the X11 settings are automatically detected and generated without a need for a configuration file, unless you are using a proprietary driver. If you have a proprietary driver, the file /etc/X11/xorg.conf is still used.

Good day, i have a laptop that i purchased with Ubuntu 12.04 pre-installed i now wish to change to win 8.1 but i dont know how to do it please assist, ive tried everything i could think of

My Suggestion would be to stick with Ubuntu. Windows 8.1 will be much slower on the same computer. However, if you do really need Windows, my suggestion would be do run it under Ubuntu using VirtualBox (free) and then install the Extension pack which you can download from the Tools menu, when you have your OS running. This then gives you full screen. For your communications, make sure that your network adapter has been set to 'Bridged'

Where can i get mastering machine learning Tips for Tackling Assignment

Mastering Machine Learning: Tips for Tackling Assignments Conquering machine learning assignments requires a blend of theoretical understanding, practical application, and strategic problem-solving. Here are some tips to help you excel:Foundational Knowledge: Solid Understanding of Concepts: Ensure you grasp the core concepts like supervised vs. unsupervised learning, different algorithms (regression, classification, clustering, etc.), and their applications. Mathematics and Statistics: Brush up on essential math and statistics, including linear algebra, calculus, probability, and statistical distributions. Programming Skills: Hone your programming skills in languages like Python or R, including libraries like NumPy, Pandas, Scikit-learn, and TensorFlow.Tackling Assignments: Thorough Understanding: Carefully read and understand the assignment instructions and objectives. Identify the specific problem you need to solve and the expected deliverables. Data Exploration and Preparation: Analyze the provided data: Understand the features, data types, missing values, and potential biases. Data Cleaning and Preprocessing: Address missing values, outliers, and inconsistencies. Feature Engineering: Create new features or transform existing ones to improve model performance. Model Selection and Training: Choose appropriate algorithms: Select algorithms based on the problem type (classification, regression, etc.) and data characteristics. Model Training: Train your model on the prepared data and tune hyperparameters to optimize performance. Evaluation: Evaluate your model's performance using metrics like accuracy, precision, recall, F1-score, or AUC-ROC curve. Experimentation and Iteration: Try different algorithms and hyperparameter settings: Compare the performance of various models to find the best fit. Cross-validation: Use techniques like k-fold cross-validation to assess modelgeneralizability and avoid overfitting. Regularization: Apply regularization techniques like L1/L2 to prevent overfitting and improve modelgeneralizability. Interpretation and Communication: Analyze results: Understand why your model performs well or poorly and identify areas for improvement. Visualize results: Use plots and graphs to illustrate your findings and insights. Clear Communication: Present your results and explain your approach in a clear and concise manner.Resources for Learning and Support: Online Courses: Platforms like Coursera, edX, Udemy, and Udacity offer comprehensive machine learning courses. Books and Tutorials: Numerous books and online tutorials cover machine learning concepts and techniques. Open-Source Libraries and Frameworks: Explore libraries like Scikit-learn, TensorFlow, PyTorch, and Keras for implementing machine learning models. Community Forums and Q&A Sites: Seek help and engage in discussions on platforms like Stack Overflow, Reddit's Machine Learning subreddit, and Kaggle forums. University Resources: If you're a student, leverage university resources like libraries, workshops, and professors' office hours. Remember: Practice is key: The more you practice, the better you'll understand the nuances of machine learning and improve your problem-solving skills. Start with simple projects and gradually increase complexity. Don't be afraid to experiment and try different approaches. Seek help when needed and learn from others' experiences.

I need a product key

Have you actually purchased Visio, or are you just trying to get it for free?
As a software guy, I would have to advise against piracy. :)
There are several ways to get Visio for cheap. If you are a student, there are discounted versions available online and in stores. Also, you can check with your school for even cheaper options sometimes. Try the university bookstore if available. Or a Computer Science department maybe.
If you are working, and your company uses MS Office applications, find out if they have the "Microsoft at Home" program. You can get MS Office applications for really cheap that way. I can get Visio through my company's "Microsoft at Home" program for a few dollars.
