Extracting and Organizing Content from Older Websites: A Solution for Structured Documentation Including Mouse-Over Images

Introduction Extracting data from older websites is a technical challenge that goes beyond simple copy-pasting. The example website provided illustrates this perfectly: its outdated design, reliance on mouse-over interactions, and lack of structured export options create a perfect storm of extraction difficulties. This article dissects these challenges and provides a roadmap for extracting both visible content and mouse-over images while preserving data integrity. The Core Problem: Legacy Technology Meets Modern Needs The website's URL parameters ( screen_width=0&screen_height=0 ) immediately signal a legacy system likely built for a bygone era of fixed-width displays. This design choice breaks modern scraping tools that expect responsive layouts. The mouse-over images, critical to the site's content, are dynamically loaded via JavaScript , meaning they don't exist in the initial page source. This requires simulating user interactions to trigger their appearance, a task beyond basic HTML parsing. Why Manual Extraction Fails Attempting to manually save images or copy text from this site is a losing battle. The mouse-over images, for instance, are not directly downloadable – they're embedded in JavaScript events. Even if you could save them individually, maintaining their association with the corresponding visible content would be error-prone and time-consuming. This method also fails to scale for larger websites with hundreds of such elements. The Technical Solution: A Multi-Pronged Approach Effective extraction requires a combination of techniques: Browser Automation: Tools like Selenium or Puppeteer can simulate mouse movements to trigger hover events, capturing both visible and hidden content. This method mirrors human interaction , ensuring all dynamic elements are revealed. Network Request Inspection: Analyzing the website's backend requests using browser developer tools can reveal direct URLs for mouse-over images , bypassing the need for hover simulation. This

Android 17 arrives on Pixel phones today

Following its official debut last month, Google is now rolling out Android 17 to compatible Pixel phones, alongside additional exclusive features as part of the June Pixel Drop. Not every feature announced alongside the OS at the pre-I/O Android Show is available today though. Android 17 itself is arriving on Pixel phones today, and Google […]

The Reference Check Questions Nobody Asks AI Vendors

I have done this process wrong more times than I would like to admit. You call the references the vendor sends you. Three customers, all happy, all articulate, all saying roughly the same things. You hang up feeling good. You sign. Six months later you are dealing with a support team that responds every 72 hours and a renewal quote that is 40% higher than year one. The reference check told you nothing useful. Not because the customers lied. Because you asked the wrong questions. Here is what I ask now. "How many people at the vendor have you spoken to in the last six months?" One contact who handles everything and is sometimes slow — that tells you something. A team of people across sales, technical support, and leadership — that tells you something different. Enterprise AI vendors with thin account teams show their limitations at exactly the moment you need them most: when something breaks at the worst possible time. "Tell me about the last time something broke in production." Not IF something broke. Something always breaks. I want to know what happened next. Did the vendor show up? Did they communicate clearly while the issue was live? Did they follow up after closing the ticket, or did they close it and disappear? The answer to this question tells me more about a vendor than any product demo. "What do you know now that you wish you had known before signing?" This question works because it is framed as advice, not criticism. Reference customers who would never say "this product has problems" will happily answer this one honestly. Listen for anything about pricing surprises, scope limitations that only appeared after deployment, or feature gaps the sales team glossed over. "When you renewed, did you evaluate alternatives?" Renewal is the honest signal. A customer who renewed without looking elsewhere is genuinely satisfied. A customer who looked at three other options and came back is someone who chose this vendor over real competition. A customer who is approachin

Fast Automatic ML Hyperparameter tuning Using Optuna (w. MLflow model registry and IRIS DB)

This article presents a straightforward approach to automatically and efficiently tune hyperparameters for machine learning models using Optuna as the optimisation framework. We explore how to use both Optuna’s native storage options and InterSystems IRIS as a database backend to track the progress of hyperparameter searches. We also show how MLflow can be used to monitor experiments and manage models through its tracking and model registry UI. This article is based on this Kaggle Notebook , which you can run and directly edit yourself. When training ML models, the choice of hyperparameters can strongly influence performance. They are not the only factor, but they can significantly affect both convergence and generalisation. Tuning hyperparameters manually takes a lot of effort. This is especially true because hyperparameters interact with each other, so tuning them independently is usually not enough. For example, higher regularisation may require a lower learning rate for more stable optimization. A more complex model may require stronger regularization to avoid overfitting, but at the same time, a very small learning rate on a complex model can make learning too slow. Optuna is an MIT-licensed open source library, which allows commercial use, that automates hyperparameter search for ML models developed with the most popular frameworks such as scikit-learn, PyTorch, TensorFlow, and LightGBM. It works by defining a search space and an objective metric to either minimize or maximize. Optuna then explores the search space efficiently to find well-performing configurations. Here we use Optuna to tune a LightGBM model on a dummy dataset and show how to scale the search using shared database storage. We will also use MLflow for experiment tracking and model registry, and IRIS DB as a possible Optuna storage backend for concurrent studies. We will use the California Housing dataset, commonly used in ML examples, to populate IRIS tables and run the tuning workflow. Note:

The Cybercab is the lightest, most efficient Tesla ever made

Against all odds, the Tesla Cybercab is in production. And while Elon Musk's company may not have a very coherent plan for the tiny, autonomous two-seater, it's still taking the necessary steps to certify the EV's legitimacy. As such, Tesla recently filed paperwork with the Environmental Protection Agency that reveal many of the Cybercab's specs, […]
