RubyConf holds a special place in my heart. It was the very first tech conference I attended after receiving a scholarship fresh out of Flatiron School back in 2017 (you can read about my experience here ), and then in 2021, it was the stage for my first conference talk in Denver. Now, in another first, I joined the Program Committee for RubyConf 2026 to help put the program together, and what a program it is! We have an absolutely amazing lineup this year, and I'm so excited to see it come to life! Who else is planning on attending? Let's make plans to meet up and say hi!

Because a reality wasn't given to us and is not there; but we have to make it ourselves, if we want to be; and it will never be one for ever, but constant and infinitely changeable. Luigi Pirandello, One, No One, and One Hundred Thousand Pirandello wrote this about the human condition. He didn't know he was describing the future of the internet. The web we know is about to disappear Not slowly. Not gradually. The web page, as the default unit of human navigation, is about to disappear: it will strip itself of everything we call "interface" and what remains will be only what it always was underneath — data, structure, instruction. The enticing homepages. The banners. The product carousels engineered by UX teams to capture attention in the first second and a half. The brand colors. The call-to-action buttons optimized for conversion rate. All of this is designed for a human eye that navigates alone. That eye is about to delegate. The agent that browses for you Imagine you want to buy a pair of shoes. Today you open a browser, search, filter, compare, go back, reopen the tab you closed, forget what you were looking for, start again. In a few years — maybe less — you will tell the agent what you want. The agent will already know that you have wide feet, that you prefer leather to synthetic, that you're looking for something for a wedding in June but deep down you want something that works afterward too. It will know that today you're in a practical mood, not an aspirational one. That you've spent a lot this month. The agent won't open a homepage. It will query a data structure. It will receive prices, availability, variants, return policies. It will build for you — and only for you, and only in that moment — a presentation tailored to measure. Colors that belong to you. Texts that speak your language. Images generated for your aesthetic sensibility of that day. The same store. Five billion different versions. One for each person, one for each moment. One, No One, and On

Something I keep noticing across teams and orgs that are actually getting value from AI versus the ones that aren't. The difference rarely comes down to the model or the algorithm. Most organizations are already drowning in data. Logs, metrics, alerts, reports, dashboards, tickets. The information exists. The bottleneck is what happens after the data shows up. How long does it take to interpret what the signal means? Who decides what to prioritize when three things need attention at once? How fast can the right people coordinate a response once a decision is made? That's where AI actually earns its keep. Not by replacing the human in the loop but by compressing the time between something happening and someone doing something useful about it. Signal to understanding to action. That's the chain that matters. Think about it in terms you deal with every day. A vulnerability gets disclosed. The CVE exists, the advisory is public, your scanner picked it up. None of that is the bottleneck. The bottleneck is figuring out which of your services are affected, who owns them, how bad the exposure actually is in your specific context, and getting a patch scheduled before someone exploits it. AI that helps you answer those questions in minutes instead of days is genuinely valuable. AI that and adds another dashboard to look at isn't. This applies across the board. Incident response, infrastructure management, risk assessment, customer systems, operational workflows. The teams getting real value aren't the ones with the fanciest models. They're the ones who figured out where their decision bottlenecks actually are and pointed AI at those specific gaps. The strategic advantage is rarely in the algorithm. It's in organizational responsiveness. How fast can you go from "something happened" to "we're handling it". The AI is just the thing that compresses that timeline. Where's the biggest decision bottleneck in your current workflow?

We’ve all been there: every year, you get a physical, receive a thick PDF full of blood markers, glance at the "normal range" checkmarks, and toss it into a digital folder titled "Health Stuff" to be forgotten. But what if I told you that those isolated data points are actually a time-series story of your biological aging? In this tutorial, we are going to build a Longevity Knowledge Graph . We will leverage GraphRAG (Graph-based Retrieval-Augmented Generation) , Neo4j , and Unstructured.io to transform a decade of messy medical PDFs into a structured intelligence layer. By the end of this post, you'll be able to query your health history with context that standard vector search simply can't grasp—like "How has my fasting glucose trended relative to my BMI over the last five years?" If you're interested in advanced data engineering patterns or looking for more production-ready AI health architectures, I highly recommend checking out the deep dives over at WellAlly Blog , which served as a major inspiration for this build. Why GraphRAG? (The Problem with Vector Search) Standard RAG (Retrieval-Augmented Generation) is great at finding a specific needle in a haystack. But if you ask, "What is the relationship between my Vitamin D levels and my bone density over time?", a vector database might just pull three separate paragraphs. GraphRAG allows us to: Connect Entities : Link a Blood_Metric (e.g., LDL) to a specific Time_Point . Traverse Relationships : Follow the path from User -> Report -> Marker -> Trend . Global Reasoning : Summarize high-level health trajectories across multiple years of data.

Meme Monday! Today's cover image comes from the last thread . DEV is an inclusive space! Humor in poor taste will be downvoted by mods.

Quick share. Been running into this enough times across NetSapiens deployments that it's worth flagging. Scenario: Call gets placed or transferred between two domains on the same NetSapiens platform. The call connects fine. Audio works. But the caller ID showing up on the receiving side is wrong. It's showing the local extension or domain user instead of the actual originating caller. If you check the NetSapiens Known Issues page, this maps to NMS-2518. It shows up specifically when calls cross domain boundaries during hold or transfer. The fallout is mostly cosmetic but it matters for anyone running multi-tenant reseller deployments. Your customer sees the wrong name in their call history. Voicemail attribution gets weird. Inter-domain analytics show calls from the wrong source. A few patterns I've seen work around it: Configure SIP header rewriting at the SBC layer to preserve the original From URI across domain hops For softphones that pull call history from NetSapiens API directly, verify which field the client is actually displaying. Some pull from orig_user , others from local_user . The discrepancy shows up clearer than you'd expect. If you're running a mobile softphone client, check whether the client is caching contact info locally and overriding what NetSapiens returns. A lot of "wrong caller ID" reports turn out to be client-side caching bugs, not platform bugs. The deeper fix is platform-side and depends on what NetSapiens version you're running. The cleaner softphone integrations route call history through the NetSapiens API rather than building it locally on the device, which sidesteps the worst of this behavior. White-label softphones that integrate natively with NetSapiens handle this more consistently than generic SIP clients. Tragofone is one example where the call history syncs through the NetSapiens softphone integration layer directly, so inter-domain caller ID is consistent with what the platform actually has. Other native integrations handle t

I haven't written articles in quite a while and I recently decided to come back to it. At work I use AI daily, so a big part of my coding tasks are delegated to agents. I try not to do the same when it comes to writing text but I don't have a clear reason for that (or maybe I do and I don't want to admit it). I am sure people can take advantage of generating text with the help of AI but at the moment I feel like prompting would not save me any time and writing the text myself would be faster. What about you? Are you using AI to write your articles? Image credit - jessica olivella, on pexels

Based on real software development trends. About a VP of Engineering who believed AI would verify its own output, 47 TODOs that shipped to production, and a $2,800,000 discount calculation error that nobody caught. This story is based on a submission from a community member. If you have a similar story or something you need to get off your chest — reach out. The next one could be yours. Act 1 · The Tech Meeting "Starting today — no more hand-written code." Marcus, the new VP of Engineering, put a slide up on the big screen. Four words: WRITING BY HAND IS OVER. I was sitting in the back row, against the wall. Seven years at this company. Three core modules that I'd built from scratch. Two production systems that ran the company's primary revenue stream. Now someone was telling me — don't write anymore. The room went quiet for about five seconds. Then people started whispering. Someone pulled out a phone and took a picture of the slide. Marcus added: "AI coding isn't optional — it's a mandatory development standard. We benchmarked this. AI writes code 400% faster than humans. Anyone still typing manually is wasting the company's time." I raised my hand. "Who reviews the code?" "AI reviews it." "Who writes the tests?" "AI tests itself." "What if AI writes something wrong?" Marcus laughed. Not a polite laugh. The kind of laugh you give someone whose question you've already decided doesn't matter. "Let me ask you something." He paused. "Do you really think — you, one person — have more training data than Orion-7? " People started laughing. Not supportive laughter. Pile-on laughter. "Or do you think the world's AI companies — hundreds of billions in investment, tens of thousands of GPUs — built something that's less reliable than one backend developer?" Nobody was looking at me anymore. Everyone was watching him, waiting for the kill shot. He didn't take it. He just smiled. "Starting next sprint, it's AI across the board. Anyone who has concerns — my door's open." Act 2 ·

Nobody wants to hear this. But the reason your software is hard to change, hard to test, and hard to explain to a new engineer isn't your tech stack. It's that your code doesn't reflect how your business actually works. Your engineers are using one word — "customer," "order," "student," "subscriber" — and meaning six different things depending on which part of the system they're touching. Your domain expert says "order" and means something completely different from what your database schema says "order" is. That gap? That's where complexity lives. That's where bugs are born. That's where senior engineers spend their Fridays. Domain-Driven Design is the discipline of closing that gap. Here's what it actually means, practically, without the academic noise. The Core Problem: One Model Trying to Mean Everything Imagine a map that tried to show subway routes, underwater hazards, hiking trails, and flight paths — all at once. It would be useless. A subway map works because it only shows what matters for navigating trains. A nautical chart works because it only shows what matters for sailing. Each map is an abstraction built for a specific purpose, valid within a specific context. Your software models need to work the same way. The moment you build a single "Customer" class that has to satisfy your billing team, your marketing team, your support team, and your logistics team simultaneously — that class becomes a bloated, ambiguous disaster. Everyone adds their fields. Nobody removes anything. The model stops meaning anything specific to anyone. This is the monolithic model trap. And most large codebases are sitting right inside it. Strategic Design: Understand the Problem Before You Touch Code DDD separates design into two layers. Strategic design comes first — it's the work you do before writing a single line of code. Step 1: Find Your Subdomains A subdomain is a slice of the business problem. Ordering. Shipping. Notifications. Payments. Inventory. These aren't your micro
