The Case for XRP: Global Payment Clearing

This article outlines how Ripple and its XRP token aim to modernize cross-border payments by replacing slow, expensive systems like SWIFT with faster, low-cost blockchain settlement. It walks through XRP’s origins, the XRPL’s high-throughput consensus model, the token’s role as a bridge asset, and Ripple’s tightly controlled escrow mechanism designed to stabilize supply and support ecosystem growth. It also highlights emerging developments such as RLUSD and the possibility of XRP escrow being used as collateral. Despite strong technical advantages—speed, low fees, scalability—and clear use-case alignment with global payments, XRP’s broader adoption remains constrained by regulatory uncertainty and ongoing SEC litigation. The comparison with SWIFT shows how blockchain-based settlement could outperform legacy messaging systems, but the article underscores that market acceptance and regulatory clarity will determine XRP’s real-world impact.  TL;DR Ripple, founded in 2012, aims to r...

GPT and GenAI for Startup Storytelling

This article shows founders how to use GenAI tools like OpenAI and Gemini as practical growth levers rather than just curiosities. By priming the model with a clear introduction of yourself, your startup, your product and your market, you can generate sharper mission statements, refine buyer personas, craft USPs, create elevator pitches and even estimate market size through iterative prompting. The key advice is to treat GenAI like a collaborative strategist: feed it context, rephrase prompts when the answers miss the mark, and use each iteration to deepen clarity. Done well, this becomes a fast, low-cost way to validate messaging, explore positioning and improve sales and marketing outputs that would otherwise take days of manual work. OpenAI and Gemini   are the most used GenAI tools today; the first one has a massive Microsoft investment, and the other one is the one from Google. But did you know that you can also use them to optimize and hack your startup?  For startup...

Indexing PostgreSQL with Apache Solr

This article explains how to offload heavy IP search and filtering workloads from PostgreSQL to Apache Solr to gain speed, scalability and richer query capabilities. PostgreSQL remains the system of record for IP ranges and geolocation data, while Solr—backed by Lucene’s inverted indexes—handles fast range lookups and flexible text queries over fields like country, state and city. The piece walks through creating a Solr core, defining an IP-focused schema, wiring PostgreSQL to Solr via the DataImportHandler, and running full imports so Solr can be queried for IP ranges and geo filters with simple syntax. The takeaway: combining Postgres for storage and Solr for search yields a robust, scalable IP management stack that outperforms pure SQL approaches for complex, high-volume search use cases. Searching and filtering large IP address datasets within PostgreSQL can be challenging. Why? Databases excel at data storage and structured queries, but often struggle with full-text search and ...

Some fun with Apache Wayang and Spark / Tensorflow

Apache Wayang is an open-source Federated Learning (FL) framework developed by the Apache Software Foundation. It provides a platform for distributed machine learning, with a focus on ease of use and flexibility. It supports multiple FL scenarios and provides a variety of tools and components for building FL systems. It also includes support for various communication protocols and data formats, as well as integration with other Apache projects such as Apache Kafka and Apache Pulsar for data streaming. The project aims to make it easier to develop and deploy machine learning models in decentralized environments. It's important to note that this are just examples and they may not be the way for your project to interact with Apache Wayang, you may need to check the documentation of the Apache Wayang project ( https://wayang.apache.org ) to see how to interact with it. I just point out how easy it is to use different languages to interact between Wayang and Spark. Also, you need to mak...
