Inside Swift's plan to modernize thousands of Ansible Playbooks - and govern automation at scale
At Red Hat Summit 2026, SWIFT shared the approach they’re rolling out — including the pilot results that informed it, and the scale they’re targeting next. Imagine running automation that touches roughly one third of global GDP every day. Tens of thousands of VMs, network devices in production, elevated privileges across production systems — and every playbook you run is, effectively, a software supply chain. That is the everyday reality at SWIFT, the secure financial messaging backbone connecting 11,000+ financial institutions across more than 200 countries. At Red Hat Summit 2026, Suvasish Ghosh , Product Owner for CI/CD Engineering and DevOps Engineering Services at SWIFT, joined Gregor Berginc , CEO of XLAB Steampunk, on stage to talk about how SWIFT is using Steampunk Spotter to govern Ansible automation at this scale. Why automation at SWIFT scale needs governance by design For SWIFT, security, availability and auditability are not features added on top — they are baseline engineering requirements. Regulatory frameworks (including DORA) codify the expectations, but as Suvasish made clear on stage, governance is by design at SWIFT, not driven solely by regulation. That stance reflects a simple truth that more and more platform teams are arriving at: automation is production infrastructure, and it must be governed as such. When you run an Ansible playbook, you are executing a software supply chain — collections, modules, roles, Python packages, system packages, the execution environment, the operating system underneath. The playbook itself is just the tip of the iceberg. Errors propagate fast. The blast radius is large. And yet, until recently, most of the security and compliance attention in IT organizations went to the applications shipping to production. The automation that built and configured everything around them often slipped through. Suvasish put it directly during the session: “We spent a lot of time being compliant and secure in our application, but w

Openpyxl's Relevance for Freelance Data Cleaning and Automation in 2023: Addressing Concerns and Solutions
Introduction: The Question of Relevance Imagine you’re a college student, fresh off mastering pandas , and you’re eyeing the freelancing market for data cleaning and automation gigs. You’ve heard of openpyxl , but as you dig deeper, you hit a wall: every resource seems to peg it as a relic for handling 2010 Excel sheets . That’s it. No modern use cases, no integration with cutting-edge tools, just a dusty library stuck in the past. So, you pause. Is openpyxl still relevant in 2023, or is it a dead end for someone trying to build a competitive freelancing portfolio? This dilemma isn’t just about openpyxl—it’s about the mechanism of perception in tech. When a tool is associated with outdated formats, its capabilities are often misinterpreted or overlooked . Openpyxl’s documentation and community discourse rarely highlight its modern applications, leaving newcomers like you to assume it’s obsolete. But here’s the catch: openpyxl isn’t just a 2010 Excel handler. It’s a low-level Excel manipulator that, when paired with libraries like pandas and numpy, can handle complex tasks that these libraries alone can’t. The problem isn’t openpyxl’s functionality—it’s the information gap between its perceived and actual utility. The stakes are clear: if you dismiss openpyxl as outdated, you risk missing out on a tool that could complement your pandas and numpy skills , making your freelancing services more efficient and versatile. But if you invest time in it without understanding its modern applications, you might waste effort on a tool that doesn’t align with current demands. The question isn’t whether openpyxl is relevant—it’s whether you’re looking at it through the right lens. In this investigation, we’ll dissect openpyxl’s role in 2023 freelancing, addressing its perceived limitations and uncovering its hidden strengths. By the end, you’ll have a clear rule for deciding whether to include it in your toolkit: If your freelancing gigs involve Excel-specific tasks that pandas ca

Hybrid RAG, No-Code AI Agent Memory, & Google Workspace CLI for Agents
Hybrid RAG, No-Code AI Agent Memory, & Google Workspace CLI for Agents Today's Highlights Today's top stories delve into advanced RAG techniques, focusing on hybrid retrieval strategies to overcome limitations of vector-only search, and explore practical solutions for equipping AI agents with long-term memory. Additionally, we highlight a new unified CLI that empowers AI agents to automate tasks across Google Workspace, streamlining workflow automation. Why Vector Search Alone Isn't Enough: Hybrid Retrieval for RAG (InfoQ) Source: https://www.infoq.com/articles/vector-search-hybrid-retrieval-rag/?utm_campaign=infoq_content&utm_source=infoq&utm_medium=feed&utm_term=global This article addresses a critical limitation in current RAG (Retrieval-Augmented Generation) frameworks: the over-reliance on pure vector search. While semantic vector search excels at understanding conceptual similarity, it often struggles with exact keyword matching or retrieving information from documents that lack strong semantic context but contain vital terms. The piece advocates for hybrid retrieval, a strategy that combines semantic (vector-based) search with lexical (keyword-based, e.g., BM25) search. This combination significantly enhances the recall and precision of retrieved documents, leading to more accurate and contextually relevant responses from large language models. For practitioners, understanding and implementing hybrid retrieval is essential for building robust, production-grade RAG systems capable of handling diverse queries and document types, thereby improving overall document processing and search augmentation performance. Comment: Anyone building serious RAG apps knows vector search has blind spots. Hybrid retrieval is a non-negotiable step for production, ensuring critical keywords aren't overlooked and improving overall response quality.

Scaling User Management on Linux: Moving Beyond the Manual Script
The Scenario: The Help Desk Bottleneck From 2019 to 2021, while serving as Lead Backend Software Engineer at a fast-growing company, I occasionally support our Linux System Administration tasks. When the DevOps team encountered a critical bottleneck during an initiative to scale dozens of new server deployments, I stepped in to streamline the infrastructure processes. The DevOps team was being hampered by constant, fragmented requests from the help desk to manually create new Linux accounts for recruits testing the latest application. These interruptions were not only time-consuming but were directly preventing the team from focusing on the high-priority infrastructure deployments that define their core responsibilities. I realized that we weren't just struggling with a task; we were struggling with a scaling bottleneck. To regain the team's focus and ensure we hit our project deadlines, I decided to automate this workflow. The First Step: The Interactive Script My first objective was to develop a robust, automated shell script to efficiently create new Linux user accounts. I started with an interactive Bash script (create-user-interactive.sh) that prompted for input. This was a good educational exercise for learning the fundamentals of Bash—like useradd, passwd, and shell variables. However, I quickly learned that while interactive scripts are great for learning, they are rarely used in professional DevOps environments. Why Manual Scripts Don’t Scale As I transitioned into a more infrastructure-focused role, I realized that manual scripts fail for three key reasons: Lack of Automation: DevOps is about "Infrastructure as Code" (IaC). Asking an engineer to sit at a terminal and type prompts is slow, error-prone, and destroys the ability to automate. Lack of Centralization: In a real team, we aren't creating users on individual local machines. We manage identity across hundreds of servers. Security Risks: Hardcoding passwords or piping them through echo is a major red

How a Scanned PDF Broke My Invoice Agent in Production
Four days into a new supplier's first batch, my invoice extraction agent had filed 31 documents with amounts shifted by a decimal. Nothing raised an error. The downstream system accepted every record. The agent returned a 200 each time. The demo had run on five clean PDFs. Clear fonts, properly formatted dates, consistent layout. The extraction agent pulled vendor name, amount, due date, line items. Every field populated, every output valid. I ran it for the stakeholder meeting and it looked exactly like something you would ship. Three months in, the agent had processed around 800 invoices without complaint. Then a new supplier switched to scanned documents. Slightly rotated, thin fonts, OCR doing what it could on degraded source material. The model found text that resembled amounts and dates, and returned confident structured output. 1,247.50 read as 12,475.0. A due date resolved to a valid date three years in the future. The confidence was the problem. The model had no mechanism to say it was uncertain. It just answered. Nobody caught it for four days. What I built after The problem was not the model. The model did what it was designed to do. Find structure in text and return it. The straight pipeline from input to output had no gate in it. The fix was not more prompting or a better model. I added a validation layer between the agent output and the downstream system. It runs synchronously, takes about 80ms, and checks four things: Every required field is non-null. Amounts parse as positive numbers within a configured range for that supplier type. Dates fall within a 90-day future window. Extracted totals are consistent with line item sums, within a small tolerance. Anything failing a check routes to a review inbox instead of the queue. A human looks at it, corrects it if needed, marks it resolved. The system logs which check triggered and what the input looked like. In the first week after deployment, the layer caught 23 documents out of about 1,400. Eleven were b

Meta-Optimized Continual Adaptation for coastal climate resilience planning with zero-trust governance guarantees
Meta-Optimized Continual Adaptation for coastal climate resilience planning with zero-trust governance guarantees It started with a nagging feeling of inadequacy. I was deep into a research project on adaptive AI for infrastructure planning, studying how reinforcement learning agents could optimize sea-wall placements and evacuation routes. The models worked—beautifully, in fact—on static datasets. But the moment I fed them real-time satellite imagery of a rapidly eroding coastline or a sudden storm surge, they stumbled. They forgot previous strategies, overfit to the new event, or, worse, made decisions that violated basic safety constraints. I realized then that the problem wasn't just about better AI; it was about trust and adaptation in the face of chaos. My exploration of this challenge led me down a rabbit hole of meta-learning, continual learning, and cryptographic governance. What emerged was a framework I now call Meta-Optimized Continual Adaptation (MOCA) with zero-trust governance guarantees—a system designed not just to learn, but to learn how to learn in dynamic, high-stakes coastal environments, all while ensuring that every decision is auditable and tamper-proof. This article shares that journey, the technical breakthroughs, and the hard-won lessons from my experiments. Technical Background: The Three Pillars of MOCA The core insight behind MOCA is that coastal climate resilience planning requires three seemingly contradictory properties: Continual adaptation – The system must update its models as new data streams in (e.g., sea-level rise, storm frequency, erosion patterns) without catastrophic forgetting. Meta-optimization – It must learn the learning algorithm itself, so that adaptation becomes faster and more sample-efficient over time. Zero-trust governance – Every model update and decision must be cryptographically verifiable, with no single point of failure or authority. In my research, I found that existing approaches tackled these individually

Agent Orchestration & Workflow Automation: Dynamic Workflows, Robust Agent Patterns, and On-Commit AI Code Review
Agent Orchestration & Workflow Automation: Dynamic Workflows, Robust Agent Patterns, and On-Commit AI Code Review Today's Highlights This week's highlights focus on advancements in AI agent coordination with Claude Code's new Dynamic Workflows, a pragmatic 6-file system for reliable agent state management, and the release of peektea v2 for on-commit AI code review. Claude Code Adds Dynamic Workflows for Parallel Agent Coordination (InfoQ) Source: https://www.infoq.com/news/2026/06/dynamic-workflows-claude-code/?utm_campaign=infoq_content&utm_source=infoq&utm_medium=feed&utm_term=global Anthropic has introduced Dynamic Workflows, a significant enhancement to Claude Code, designed to improve the coordination and efficiency of AI agents in complex tasks. This new capability enables developers to orchestrate multiple AI agents in parallel, allowing them to collaborate on different parts of a problem simultaneously. Unlike traditional sequential processing, Dynamic Workflows facilitate a more natural, concurrent approach, where agents can dynamically assign sub-tasks, share intermediate results, and adapt their strategies based on real-time progress. This is particularly beneficial for large-scale code generation, complex project management, and multi-stage data analysis where distinct competencies are required from different specialized agents. The core benefit of Dynamic Workflows lies in its ability to manage dependencies and synchronize agent activities, leading to faster execution and more robust outcomes. For instance, in a coding scenario, one agent might focus on generating unit tests while another refactors existing code, both operating in parallel and integrating their work seamlessly. This dynamic coordination mechanism moves beyond simple sequential chaining, offering a powerful paradigm for building sophisticated, multi-agent systems that mirror human team collaboration. Developers can leverage this to create more resilient and adaptive AI-driven workflows,

Field-Level Provenance: Why "Trust Me" Isn't Good Enough for AI in Healthcare
Last week I wrote about why healthcare benefit data is still trapped in PDFs . The response told me something: people in this space know the problem is real. But extraction is only half the story. The harder question is: when an AI system pulls a copay amount from a carrier document, can you prove where that number came from? Not "the AI said so." Not a confidence score with no backing. Can you point to a specific page, a specific table cell, a specific paragraph in the source PDF and say: this value came from here? That is field-level provenance. And in healthcare, it is no longer optional. The Regulatory Floor Just Rose In January 2026, two state laws went into effect that changed the baseline for AI-generated content in healthcare. California SB 942 requires AI systems to disclose when content is AI-generated and to maintain audit trails. Texas HB 149 mandates transparency about AI decision-making processes in regulated industries, with healthcare squarely in scope. These are not theoretical. They are enforceable. And they are just the beginning. CMS transparency mandates tighten every year. Gartner declared digital provenance an enterprise baseline for 2026. The industry is not moving toward provenance. It has arrived. The Problem with Self-Reported Citations Most AI extraction systems today work like this: a language model reads a document, extracts values, and reports where it found them. The model does the extraction AND the citation. It is grading its own homework. This seems fine until you look closer. A language model that hallucinates a copay amount will also hallucinate the page number it came from. The citation and the extraction fail together, silently, in the same direction. In a coverage dispute that ends up in a regulatory proceeding, "the AI told us it found this on page 3" is not evidence. It is hearsay from a statistical model. What Deposition-Grade Provenance Looks Like Field-level provenance means every extracted value carries metadata from an

Integrated Biological Data Collection Platform: An Architecture for Automated Curation of Public Repositories
Introduction In contemporary research, the volume of biological data deposited in public repositories is growing exponentially. The Gene Expression Omnibus (GEO), NCBI Gene, PubMed, and UniProt accumulate thousands of new records daily, including sequences, expression profiles, scientific articles, and functional annotations. On the one hand, this scenario represents a unique opportunity for biomedical research. On the other hand, the diversity of data formats, access protocols, and metadata models creates a significant barrier: each source requires a specific collector, distinct rate-limiting strategies, and its own validation logic. Above all, the lack of standardization in data storage compromises the reproducibility of scientific studies. The need for integrated tools capable of unifying data extraction, curation, and persistence has been widely discussed. In practice, ad hoc solutions such as isolated scripts for individual repositories generate redundant work and make maintenance difficult. First and foremost, it is necessary to establish an architecture that treats data collection as a service rather than a collection of scattered artifacts. This work presents Project 1 of the Integrated Bioinformatics Platform: a containerized Biomedical Data Collector coupled with a Data Lake. Its objective is to provide a REST API capable of triggering asynchronous data collections from the four aforementioned sources, storing immutable raw data in MinIO, and persisting metadata in PostgreSQL, all while ensuring traceability and resilience. Development The system architecture is divided into three main layers. The first is the API and orchestration layer , implemented using FastAPI. Its five endpoints — POST /collections , GET /collections , GET /collections/{id} , GET /collections/{id}/download/{dataset_id} , and GET /health — expose a clean interface for initiating and monitoring collection processes. The second layer is the collector engine , composed of abstract classe

How I Made My First Dollar with Python Automation - A Practical Guide
This isn't a tutorial. It's real experience. Most articles about making money with Python are vague: "Learn Python to make money" (then what?) "Do data analysis freelancing" (how to get clients?)

I Built a One-Person AI QA Agency Using a Skill File and Local LLM
There is a specific failure mode in AI-assisted QA work that most tooling discussions skip entirely, and it shows up earliest when you are working solo on a real engagement. Every new chat session is stateless. You paste the ticket, describe the feature, explain your severity logic, set up the context, and by the time the AI is actually useful, you have rebuilt your methodology from scratch for the third time that week. That is not a workflow problem you fix with better prompts. It is an architecture problem, and the fix is a skill file. QAJourney has a full breakdown of this system at qajourney.net/ai-qa-workflow-for-real-projects, including the actual skill files as free downloads. The short version: a skill file is a context document you load as a system prompt. It carries your test surface tiers, your three-path testing framework, your bug report format, your severity and priority logic, your Playwright conventions, and an explicit definition of what the AI does and does not get to call. Load it once per session. The AI operates inside your methodology from the first message instead of a blank slate. The local LLM layer solves a different problem. On a freelance or retainer engagement, tickets contain real product logic and real client data. Sending that to a cloud API on every session is a data exposure question whether or not it rises to a compliance issue. Running Ollama locally with the same skill file as system context keeps the engagement data on the machine. For the output quality required on QA tasks, current 7B to 14B models are sufficient. The cost at zero marginal per token makes it infrastructure rather than a service you pay by the session. The three-role setup in the workflow: engineer as judgment layer, cloud AI loaded with the skill file for complex reasoning and active session output, local LLM for lightweight tasks and client data work. The skill file is the constant across all three. The part that took time to internalize: AI dev teams already

5 Anthropic Prompt Caching Patterns That Cut My API Bill 70%
System-prompt caching alone cut repeat-call costs by half Tool definitions cache separately, perfect for agent loops Conversation history caching pays off after turn three 1-hour TTL beats the default 5 minutes for batch jobs My Anthropic API bill dropped 70 percent last month and I did not change a single model. I changed where the cache breakpoints went. Here are the five patterns I now use on every Claude integration I ship. Pattern 1: Cache The System Prompt First The system prompt is the cheapest win and most people skip it. My agents run with a 4,000 token system prompt that explains the role, the output format, the safety rules, and a few examples. That prompt never changes inside a session. Before caching, I paid full input price for those 4,000 tokens on every single call. With an agent that loops 30 times to finish a task, that is 120,000 tokens of pure repetition. The fix is one parameter. I add a cache_control block with type: "ephemeral" to the last content item in the system prompt array. The first call writes the cache and costs slightly more (cache writes carry a small premium). Every call after that reads the cache at roughly one tenth the input price. Here is the rule I follow: the cached block has to be at least 1,024 tokens for Claude Sonnet, or it gets ignored silently. My 4,000 token prompt clears that easily. If your system prompt is short, this pattern does nothing, so do not bother adding the breakpoint to a 200 token instruction. The order matters more than people expect. The cache works as a prefix. Everything before the breakpoint gets stored. Everything after it is read fresh. So I put the stable stuff (role, rules, examples) up top and the volatile stuff (user query, current date) down below the breakpoint. Reorder this wrong and your cache hit rate collapses because the prefix changes on every call. One real number from my logs: a document-classification job that runs 2,000 times a day. The system prompt is 3,800 tokens. Caching it sav

LLM Deal Flow Automation in CRM
In This Article The Deal Intelligence Gap Data Model Design Transcript Analysis with Claude Automated Follow-Up Drafting PostgreSQL JSONB Storage Putting It Together The Deal Intelligence Gap Most CRM systems are excellent at storing what happened — call logged, email sent, stage updated — and poor at capturing what was learned. A sales call produces qualitative intelligence that is genuinely valuable for deal strategy: what objections surfaced, how strongly the prospect signaled interest, what next steps were agreed to, and what risk flags the conversation revealed. That intelligence almost never makes it into the CRM because it requires someone to spend 15 minutes synthesizing unstructured notes into structured fields. Large language models change this equation. Given a call transcript, Claude can extract structured deal intelligence in seconds — categorizing sentiment, identifying specific objections, recommending stage movement, and flagging risk signals — with accuracy that equals or exceeds what a well-trained sales analyst would produce manually. Data Model Design The data model centers on two tables. The deals table stores core deal attributes as a JSONB column, which allows flexible schema evolution without migrations as the intelligence fields change over time. The deal_activities table records each interaction — calls, emails, meetings — with the raw content in TEXT and the extracted intelligence in a separate JSONB column. A GIN index on both JSONB columns enables fast attribute queries across the deal pipeline. CREATE TABLE deals ( id UUID PRIMARY KEY DEFAULT gen_random_uuid (), company TEXT NOT NULL , contact TEXT , stage TEXT , attributes JSONB DEFAULT '{}' , created_at TIMESTAMPTZ DEFAULT now (), updated_at TIMESTAMPTZ DEFAULT now () ); CREATE TABLE deal_activities ( id UUID PRIMARY KEY DEFAULT gen_random_uuid (), deal_id UUID REFERENCES deals ( id ), activity_type TEXT , raw_content TEXT , intelligence JSONB , created_at TIMESTAMPTZ DEFAULT now () )

How a Small Product Sync Automation Changed Onboarding at Scale
How a Product Sync Automation Project Transformed Customer Onboarding When people think about impactful engineering work, they often imagine distributed systems, high-scale infrastructure, or complex algorithms. One of the most impactful projects I worked on wasn't any of those. It was solving a seemingly simple problem: Keeping product data in sync across multiple retail systems. Years later, our CEO still remembers how much smoother customer onboarding became after this project. The Context: What is Commerce Connect? At Casa Retail AI, we have an internal platform called Commerce Connect (CC) . Commerce Connect acts as the central Product Information Management (PIM) system and serves as the source of truth for product information. Under the hood, it is built on top of a customized version of the open-source e-commerce platform Spree Commerce , extended with multi-vendor and multi-tenant capabilities. Its primary responsibility is simple: Collect product information from multiple retail ecosystems and distribute it to every Casa product that needs it. Once product data enters Commerce Connect, it is synchronized to multiple downstream systems. Why Product Data Matters Many applications inside Casa depend on product information. Product Consumers Once product data enters Commerce Connect, it is distributed to multiple systems across the Casa ecosystem. Customer-Facing Applications Several products rely on product information to provide context and improve customer experience: Lead management applications use product information during customer interactions.
