...to slide up and down through bearings or bushings without friction. Stainless steel won't rust if you leave the machine in the garage or a damp equipment shed. • Where to get it: McMaster-Carr (Search: "Rotary Shafting"). How the Assembly Works To get that "bobbing" motion you want, the setup looks like this from the inside out: 1. The Outer Pipe stays still and is bolted to the floor/base. 2. Linear/Rotary Bushings are pressed into the top and bottom of the outer pipe. These are special bearings that allow the inner shaft to both spin and slide up and down at the same time. 3. The Inner Shaft sits inside those bushings. 4. The "Wave" Cam is a piece of metal shaped like a roller coaster track welded to the top of the outer pipe. 5. The Fo...

I’m running a head-to-head study of several classic and deep-learning classifiers—KNN, Logistic Regression, linear SVM, Kernel SVM, and a simple feed-forward Neural Network—using both the original MNIST digits and the Fashion-MNIST images. I want the two datasets treated with equal weight so that any conclusions hold across handwriting and apparel imagery alike. Before training, every image batch must pass through Normalization and Feature Scaling, and I’d like to see creative yet reasonable Data Augmentation (rotations, shifts, noise, etc.) applied consistently to both datasets so we can observe how each model copes with expanded variability. For each classifier, I need precision, recall, and F1-score reported per class and averaged (macro and weigh...

I have a working Python script that already tackles a portion of my scientific-data analysis, but it needs a full refresh so it can: • clean and preprocess raw experimental files (handling missing values, unit conversions, outlier checks) • run the required statistical analyses (descriptive stats, hypothesis testing, regression where relevant) • generate clear, publication-quality visualisations of the results The current code is organised in a single file. I want it refactored into well-named functions or classes, documented with concise docstrings, and wrapped in a short Jupyter notebook that demonstrates the new workflow from import to final figure. Please keep any existing logic that is still valid but feel free to streamline it with modern libraries&mdas...

...The suite must cover the current regression scenarios of my application and run reliably on Chrome (other browsers may follow later, but Chrome is the immediate need). Here’s what I’m expecting from you: • A clean Maven/Gradle-based project written in Java, using Selenium WebDriver and a test runner such as TestNG or JUnit • Page Object Model (or an equally maintainable pattern) so future tests are quick to add • Parameterisation for environment URLs and credentials, pulled from a config file or environment variables • Clear, human-readable reports (Allure, Extent or similar) generated automatically after each run • Command-line hooks so the tests can be triggered from our CI pipeline later on Acceptance criteria 1. All existing smo...

Scope • Front-end only: all backend APIs, authentication endpoints, and notification hubs stay as they are. • Preserve every screen, navigation flow, and binding so users experience no functional regression. • During the move I also want a few targeted improvements; I’ll share mock-ups once we start, but think modernised UI components and any MAUI-native performance gains that make sense. Deliverables 1. New MAUI solution with organised project structure, clean XAML/C#, and commented code. 2. Build and publish pipelines (or detailed steps) that generate ...

Here’s what I’d like done: • Configure an AWS stack (EC2 or Elastic Beanstalk, RDS/ Aurora if needed, S3, IAM, Route 53—the exact mix is flexible) and deploy the current build so it’s publicly reachable on its own sub-domain. • Spin up a dedicated testing space that mirrors production settings closely enough for functional and regression tests. I’m open to your recommendation on whether this should be a separate staging or QA environment, as long as the path from commit to deploy is smooth. • Automate the pipeline: connect our GitHub repo to CI/CD using CodePipeline, CodeBuild, or another tool you trust, with unit tests executed on each push and automatic promotion...
