HOW TO Filter Products on Open Food Facts by Country (India) Using DuckDB & Superset

Image
Open Food Facts (OFF) is a crowd-sourced database of food products from around the world.  Somewhere in the world, a shopper scans the barcode on a packet of biscuits and adds basic product details. Another person photographs a package label for the same product in Hyderabad. A volunteer in France fixes a typo.  That's Open Food Facts, a volunteer-built, openly licensed database of food products that's continually changing and growing. Each product is identified by a barcode and carries ingredients, nutrition facts, brands, labels and more. The whole database has millions of products, and let's say you only want the products recorded as being sold or available in one country like India. There are multiple ways to extract a subset of the OFF database. I have already tried using the daily dump available on Hugging Face through Google Colab and GitHub Actions in the past but it blew my mind that using the OFF deployed Apache Superset , you can execute a SQL query in a brows...

HOW TO dynamically generate a Word document with custom header & footer

Image
Way back in 2004, a project I was working on required a web page to be exported as a Word document (.DOC). Without relying on any components, I utilized the Office XML & HTML technique to implement this feature. I posted my sample on CodeProject to seek feedback. Over the years, I've received some generous comments & feature requests. Many wanted to know how to add a header & footer to the dynamically generated Word document. With the help of the Microsoft Office HTML and XML Reference , I devised a hack to add a lacklustre header and/or footer . Some folks wanted to customize the contents of the header & footer but when they tried with my hack that offered limited functionality, the header/footer text showed up in the document body to their annoyance. This July, an ingenious developer posted a hack that can overcome this problem, in the Comments section of my CodeProject article. His practical workaround was to pack the duplicating header/footer text inside a t...
