FiddlerCap makes HTTP Traffic Capture easier

As a web developer, if you would like to debug HTTP traffic of web pages that your site users are having problem with, you can have the end-users record the traffic details as a Session Archive Zip (.SAZ) file & then send it to you.

Talking about Traffic Import options with Fiddler in his session titled "Advanced Web Debugging with Fiddler" at MIX10, Eric Lawrence highlights a lesser known tool called FiddlerCap. For non-technical folks, FiddlerCap Web Recorder is a lightweight version of Fiddler that's easier to use than Fiddler. The interface is more intuitive with Start Capture, Stop Capture, Save Capture buttons.

IE9 is going to have a Network tab like Firebug under Developer Tools (accessible through the menu or F12 key). The traffic details collected through the IE9 Network tab can be exported in a soon to be standardized format called HAR (or HTTP Archive Specification). The XML version of the HAR format file that is emitted by can be opened within Fiddler for analysis. As more tools start respecting the HAR format, the Web Performance Analysis & Optimization tools will be able to exchange information seamlessly.

GitHub Copilot Q&A - 1

Image
Key takeaways from the talk in Q&A format - What is GitHub Copilot and how does it work? GitHub Copilot is a suite of tools designed for code completion. It works by analysing the code and comments you type in your IDE and sending that context to GitHub. Copilot then uses OpenAI's language model (in December 2024, it is GPT 4o by default and you can also choose the preview versions of o1-mini & o1-preview if you like) to understand your intent and generate suggestions for code completion. You can then accept, reject, or modify these suggestions. What context does GitHub Copilot consider when making suggestions? Copilot considers the entirety of the file you are currently working on, not just the code from your cursor position upwards. It also analyses the content of other open tabs in your IDE, starting with those closest to the current tab. This helps Copilot focus on the most relevant information. Is it necessary to meticulously manage open tabs for Copilot to work effect...

Maven Crash Course - Learn Power Query, Power Pivot & DAX in 15 Minutes

Image
In the Maven Crash Course " Learn Power Query, Power Pivot & DAX in 15 Minutes ", Chris Dutton walks through a hypothetical business case while showcasing the power of modern Excel tools like Power Query, Power Pivot and DAX. Power Query is used to extract, transform, and load data from external sources like SQL databases, PDF and CSV files. A relational model is created to join the tables without writing a single formula. Exploratory analysis is done using Power Pivot and Data Analysis Expressions (DAX). Data Analysis Expressions is the language that we can use to define new calculated columns and measures to enhance our Data Model instead of the traditional cell formulas that we'd typically use if our data was stored in worksheets. Pivot Charts and slicers are used to design a simple interactive report that the sales managers can use to analyze revenue trends and product performance.
