GenAIScript - Comment Code with AI

Documenting code is a necessity, and AI LLM models simplify the task of commenting while coding.
GenAIScript is an open-source scripting environment that streamlines tasks for AI analysis by automating complex processes within a cohesive scripting framework. It facilitates ingestion of diverse document formats and supports the generation of structured outputs.
A batch processing approach is implemented using an AI-powered Command-Line Interface (CLI) that runs on the code-base and uses primarily local LLM models.
The author used the RAG approach with Abstract Syntax Tree (AST) as a way to reduce context on which LLM has to reason, provide hierarchical views of code's syntax and abstracting away irrelevant details, to divide a source code file into meaningful pieces.
Tree-Sitter, an AST tool with an incremental parsing library that can build a concrete syntax tree for a source file, was used by the author to implement the Commenter CLI that generates high-quality comments for existing code within a codebase.
The Commenter CLI is composed of the following steps – loading each source file, submitting its content to the AST parser, which extracts code chunks, invoking LLM model, which reviews implementation and produces a comment based on the chunk, Comment + Chunk is provided back to the AST parser to verify that LLM has produced is valid code for given language, and finally joining all chunks and related comments.
The Commenter CLI method saves time and improves the overall quality of documentation, making the codebase easier for developers to understand and work with.
The qwen2.5-coder:7b model worked well for code commenting tasks, which the author used for the first release of the tool available on the Github project.
Overall, the Commenter tool makes it easier for developers to improve the readability and understandability of their code.

“Top Selenium Interview Questions and Answers to Ace Your Next Job Interview”

Selenium is a widely used automation tool. It is a suite of tools that helps to automate web browsers. The core of Selenium is Selenium WebDriver, which drives the browser directly.
Selenium IDE records the user actions on the web browser and exports them as a reusable script. It was developed to speed up the creation of automation scripts.
Selenium Remote Control (RC) server allows users to write application tests in various programming languages. Unlike RC, WebDriver does not require an additional server and interacts natively with browser applications.
Selenium Grid was designed to distribute commands to different machines simultaneously. It allows the parallel execution of tests on different browsers and operating systems.
Functional Testing involves the verification of every function of the application with the required specification. Regression Testing is a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine.
Selenium offers various locators to locate web elements, including link, partial link, name, tagname, classname, xpath, and CSS selector locators.
There are three types of waits in Selenium- Implicit, Explicit, and Fluent. Each of them waits for a different condition before proceeding with the code.
Methods like refresh(), navigate().forward(), and navigate().back() can be used to refresh the page and navigate through the website.
driver.close() method closes the browser’s current window, while driver.quit() method closes all open browser windows.
JavaScriptExecutor can be used to perform functionalities like scrolling down to the desired location,entering text into a textbox, maximizing or setting the window size.
The objects of the Select type can be initialized and used to perform operations like selecting an option that displays text matching the given argument.

Building a File Upload App with TypeScript, React, and Auto-Drive API

A simple app for uploading files to a Distributed Storage Network (DSN) using Autonomy's Auto-Drive API leveraging RadzionKit repository has been created.
The app will consist of a single page with an API key entry and file management views.
API key is stored with the AutoDriveApiKeyGuard component which will allow to validate the API key dynamically.
Local storage is used to store API key.
The UploadFile component handles the upload process showing spinner while the file is being uploaded and displays an error message if the upload fails.
Uploading files is straightforward with the Auto-Drive SDK.
PaginatedView and useInfiniteQuery are used to handle pagination for querying the API.
UseCurrentFileProvider is used to provide the current file to its children.
The ManageFile component displays the file name or CID and includes buttons for downloading and deleting the file.
Deleting a file calls the Auto-Drive SDK’s markObjectAsDeleted function with the file’s CID, and we invalidate the list of files to refresh.

The Evolution of Programming: From Manual Craft to Intelligent Design

In the early days, programming involved creating detailed algorithms and following explicit rules using languages like C, Java, and Python.
With the advent of machine learning, programming shifted towards teaching machines using examples and patterns rather than explicit instructions.
Today, programming is a collaborative effort between humans and machines, with machines processing large amounts of data, adapting to new contexts, and freeing up humans for creative problem-solving.
Challenges in this evolution include biases in training data, the complexity of modern systems, and ethical implications, but hybrid models and new tools are emerging to address these challenges.

A mid-career retrospective of stores for state management

The use of sophisticated stores can establish a view-level source of truth to organise feature-specific state, especially when an app requires different parts to access information specific to a particular function.
Angular’s MVC structure movements service classes that perform state passing between views; instead of sophisticated stores, observables with RxJS were used to subscribe to streams of asynchronous event data.
The disaster that arose from not using a state management solution led to long-winded, overly imperative ('if-abc, else if xyz, else if jkl...'), and much harder to maintain and debug code.
Stores that are not well-architected can act like daisy-chained information flows, leading to confusion and harder maintenance.
Creating a store for every app feature can lead to unnecessary complexity and coupling.
Using a store for state management is ideal when there is complex, domain-specific logic that needs to be updated carefully.
React's hooks and Context API and Vue's computed(), ref() and watch() functions offer 'lightweight' options for state management.
Where needed, it is wise to choose a strategy before entropy takes hold.
Frameworks aim to reactively update the UI when the data changes, manage side effects, and distinguish between local, shared, and global state.
It is easy to get to a place where no single pattern is used, and it may become unsustainable to manage state within one or two components, and this is where a store would help.

OOP Simplified: Breaking Down the 4 Core Principles

A constructor is a special method used to initialize an object when it is created in object-oriented programming.
Inheritance is one of the key principles of object-oriented programming (OOP) which allows a class to inherit properties and methods from another class.
Polymorphism enables the same entity (like a method or object) to behave differently in various scenarios.
Method overloading takes place in the same class. It is determined during compile-time and its key feature is that it has different parameter lists.
Method overriding is determined during run-time and happens between parent and child classes. Its key feature is that it has the same name and parameter list.
There are multiple types of inheritance namely single inheritance, multilevel inheritance, and hierarchical inheritance.
The 'this' keyword refers to the current object of the class and 'super' keyword is used to refer to the parent class in a child class.
Inheritance allows you to reuse code instead of rewriting it and create a hierarchy between classes for better organization.
Polymorphism enables the same interface to represent different behaviors depending on the context.
Encapsulation and Abstraction are two more pillars of object-oriented programming and will be explained in detail in the next blog.

Understanding Web Authentication: Sessions vs. JWTs

Session-based authentication involves the server creating a session upon login and sending a unique session ID to the client. The client includes the session ID with each request for the server to authenticate the user.
Key benefits of session-based authentication include easy revocation and centralized security. Challenges include distributed systems and added latency.
JWT-based authentication involves the server generating a signed JWT after successful login. The client stores the JWT and sends it with each request for the server to verify and authenticate the user.
Key benefits of JWT-based authentication include being stateless and scalable, and compatibility with microservice architectures. Challenges include token expiration and security trade-offs.

Blue screen of death

The blue screen of death (BSOD) was initially designed to grab attention with its stark blue background and cryptic warning.
A programmer added a hidden Easter egg message as a joke, but it was rarely seen by users due to the quick appearance of the BSOD.
The BSOD appears when Windows encounters a critical error that it cannot recover from.
Although it may not be as common or terrifying as before, the BSOD remains an iconic part of Windows history.
