Tech Tips, Tricks & Trivia

Dan Go, a High Performance Coach to entrepreneurs points that an average person spends 4-5 hours a day on their phone . If they did this from the ages of 20 to 80 they would have spent a total of 10+ years of their lives on a screen. It's not the phones themselves that cause addiction. Addiction largely comes from the apps themselves. They are designed to capture your attention by altering some serious chemistry in your brain. He has the following suggestions to tackle phone addiction: Cultivate awareness by tracking screentime. Most smartphones come with a built-in feature that is usually called "Screen Time", "Digital Wellbeing" or a similar variation. Typical view on Vivo phones Typical view on Samsung phones Typical view on iPhone Remove triggers. Only keep essential apps on your phone. Make your phone ugly. Set your phone to greyscale/black & white. Change the environment. The best way to reduce phone time is to remove it from your environment entirely.

Thinking Like an Analyst is a 5-hour course for aspiring analytics & BI professionals looking to build the foundation for a successful career to understand what it takes to be a Data Analyst.

From  The Executive's Guide to Generative AI  -  When evaluating projects, consider the feasibility, actionability, affordability, anticipated business value, and ultimate return on investment of each generative AI project. Commonly used generative AI Key Performance Indicators: Accuracy - Measure the accuracy of the generative AI model in producing relevant and correct outputs. This can be quantified using metrics such as precision, recall, F1 score, or mean squared error, depending on the nature of the use case.  Productivity - Assess the impact of generative AI on the productivity of the target persona or department. This could include metrics like the number of tasks completed per unit of time, response time, or reduction in manual effort required. Customer satisfaction - If the generative AI use case involves customer-facing applications, use customer satisfaction surveys or feedback to gauge how well the AI system meets customer needs and expectations. Cost savings - Measure

Guidance from Google's People + AI Guidebook about situations where an AI approach is probably better than a rule-based approach, and some in which it is not. When AI is probably better: Recommending different content to different users . Such as providing personalized suggestions for movies to watch. Prediction of future events. For example, showing flight prices for a trip to Denver in late November. Personalization improves the user experience . Personalizing automated home thermostats makes homes more comfortable and the thermostats more efficient over time. Natural language understanding . Dictation software requires AI to function well for different languages and speech styles. Recognition of an entire class of entities . It’s not possible to program every single face into a photo tagging app — it uses AI to recognize two photos as the same person. Detection of low occurrence events that change over time. Credit card fraud is constantly evolving and happens infrequently to

I like mobile web apps more than smartphone apps . A while ago, I discovered Minhaz's amazing HTML5 QR Code & Barcode Scanner JavaScript library . Using that I built a minimal web page that can scan a product barcode through a smartphone's mobile browser and then redirects user to the equivalent product's Open Food Facts web page to display its nutrition information. I have now extended that sample to scan an EAN-13 barcode off a packaged food product and then fetch just its name, image, Nutri-Score & Nova details using the Open Food Facts REST API .   Screenshot of the output in the Microsoft Edge browser on an Android phone Try out the no-frills  NutriScan 🥫🔍  web app and please let me know what you think. Here's the code if you're interested - Typically, the JSON returned by an API call looks like this - {     "code": "8906005504395",     "product": {         "image_thumb_url": "https://images.openfoodfacts

Paraphrased from the HBR article  How to Red Team a Gen AI Model  - A red team is a group that pretends to be an enemy, attempts a physical or digital intrusion against an organization at the direction of that organization, then reports back so that the organization can improve their defenses. Red teams work for the organization or are hired by the organization.  It is a process of testing your cybersecurity effectiveness through the removal of defender bias by applying an adversarial lens to your organization. The term was popularized during the Cold War when the U.S. Defense Department tasked “red teams” with acting as the Soviet adversary, while blue teams were tasked with acting as the United States or its allies.  In October 2023, Biden's AI executive order mandated "red teaming" - a structured hacking effort to uncover flaws in certain high-risk generative models. Red teaming generative AI is specifically designed to generate harmful content that has no clear analo
