HOW TO stretch the battery life of portable devices

Tips from a recent NY Times article on increasing the battery life of portable devices like BlackBerry, iPhone, smartphones & laptops:

  • Consider using G.S.M. over CDMA for your mobile
  • Turn down the devices' screen brightness.
  • Turn off Bluetooth & Wi-Fi when not required otherwise portable devices will continue to look for Wi-Fi or a Bluetooth headset, using power
  • If you’re in a weak signal area turn off your portable device’s mobile capabilities as your phone must work even harder to find one, decreasing battery life.
  • Set up your phone to check for e-mail and instant messages manually.
  • Put your smartphone into "airplane mode" to cut power to a minimum.
  • Disable Flash when not using wall power; Flash animations are a power hog
  • Get an app to monitor battery life and shut off various functions that cut down on a mobile device’s effective power.

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...
