New features of WebPageTest

WebPageTest.org is a free online version of AOL's open source performance analysis & optimization tool PageTest (which you can deploy on your own server).

The new features of WebPageTest were demo'ed at Velocity 2010 Lightning Demos session.

One distinct feature in PageTest is Visual Performance comparision. A Waterfall chart is what most web performance analysis tools show. With PageTest you can see how your web page actually looked like at small intervals while it was still loading. You can choose between a Film-strip view & Full-motion video to know what your site visitors see when they access a web page on your website.


WebPageTest now offers more test locations, custom bandwidth configuration, browser resource utilization info (CPU & Network bandwidth) and support for HAR (HTTP Archive Specification)

HAR is an open format for archiving & exchange performance results between web performance analysis tools. The current list of tools that support HAR is here.

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.

Oracle Cloud Infrastructure 2024 Generative AI Professional Course & Certification Exam (1Z0-1127-24)

I was happy to learn about the Oracle Cloud Infrastructure 2024 Generative AI Professional Course with video tutorials and the Certification Exam (1Z0-1127-24) from their newsletter. I found it extremely useful, timely, and relevant. The course, with about 6 hours of videos, provided me with a comprehensive view of what it takes to build a Generative AI application. Although some parts reference OCI services, much of the course remains vendor neutral. Rohit Rahi and his team at Oracle have done a great job of structuring the beginner-friendly yet comprehensive course so well, covering all the essentials across four modules. The curriculum strikes an excellent balance between depth and accessibility.  While Gen AI output is typically non-deterministic, I was surprised to learn that they can be made completely deterministic under certain conditions. Specifically, in the OCI Gen AI service, setting the temperature parameter to 0 produces consistent, deterministic output for a g...
