Hi, my name is Dan, I'm a frontend engineer and open-source maintainer. I've spent the last couple of years building Nano Kit — a lightweight, modular state management ecosystem for modern web apps: signals-based stores , a router , data fetching , i18n , and SSR support , all built on the same tiny reactive core. It recently hit 1.0 , and in this post I want to give you four honest reasons to try it. 1. It's fast At the heart of Nano Kit is a push-pull reactivity system based on the algorithm from alien-signals — one of the fastest signal implementations in the JavaScript ecosystem. I didn't use alien-signals directly, though. Nano Kit needed things it doesn't provide, so I built a dedicated fork called Agera : Signal lifecycles — you can listen to signal activation and deactivation, which powers Nano Kit's mountable stores (run setup logic on first listener, clean up on last). Real tree-shaking — Agera is designed so that only the code you use ends up in your bundle; alien-signals is not well tree-shakable. The result keeps almost all of alien-signals' raw speed. Here is how @nano_kit/store compares to other popular state management libraries in a reactivity benchmark : Library Latency avg (ns) Throughput avg (ops/s) alien-signals 294.00 ± 2.24% 3,559,763 @nano_kit/store 303.55 ± 0.75% 3,365,816 svelte/store 428.58 ± 0.61% 2,479,118 rxjs 454.74 ± 0.07% 2,250,397 nanostores 1,373.2 ± 5.96% 952,399 mobx 3,474.7 ± 1.86% 306,094 valtio 5,041.3 ± 11.46% 254,109 jotai 9,454.6 ± 16.45% 157,853 effector 24,885 ± 11.78% 62,744 @reatom/core 59,430 ± 15.61% 22,741 Benchmark was run on AMD Ryzen 5 PRO 3400G with Node.js v24.14.1 That's ~3.5× faster than nanostores and an order of magnitude faster than most atomic state managers — while shipping lifecycles and mountable stores on top. 2. It's small Nano Kit exists largely because of Nano Stores . I love its philosophy: atomic stores, mountable resources, logic moved out of components, and an obsessive focus on bundle size. Nan

What We Learned Building a Location-Aware Contact Management App Most contact apps are built like digital phonebooks. They store a name, phone number, email, maybe a company name, and then leave the user to remember everything else. That works when someone has 50 people saved. It starts breaking when someone has hundreds or thousands of professional connections from events, client meetings, referrals, business cards, conferences, online communities, and local networking groups. The hard part is not storing people. The hard part is helping users find the right person at the right time. While building a location-aware contact management app, we learned that contact data becomes far more useful when it is connected to context: where someone is, how the user met them, what they discussed, what industry they belong to, and why the relationship matters. Here are some product, UX, and privacy lessons we learned along the way. 1. A contact list is not the same as a usable network A normal contact list answers one basic question: “Do I have this person’s number?” But professionals usually need better questions answered: Who do I know in this city? Who did I meet at that event? Which industry contacts are nearby? Who should I follow up with before visiting this area? Who was that consultant I met last month? Which contacts are important but easy to forget? This is where the product problem becomes interesting. A user may technically have the contact, but still fail to use the relationship because the contact is buried inside a long list. So the first learning was simple: Saving contact details is not enough. The app needs to help users retrieve useful relationships when the context matters. That changed how we thought about the product. We were not just designing a place to store people. We were designing a system to make saved professional relationships easier to act on. 2. Location context changes the experience Most contact managers are list-first. You search by name, comp

GitLab has released version 19.2 of its DevSecOps platform, adding agentic automation aimed at the security and review work that has piled up as AI coding tools generate more code than developers can check by hand. The release, announced on 16 July 2026, brings four features out of beta or into public beta: Dependency Scanning Auto-Remediation, Security Review Flow, GitLab Duo CLI and Custom Flows By Matt Saunders

A few weeks ago a Business Manager handed me a 50-page AI-generated technical spec. The document was impressive. The perspective behind it was the problem. I had talked to him a few days earlier about a new internal tool the company needed. We discussed the use case and the requirements in depth. Later on, I discussed those same requirements with my IT team and assigned them the job of making the technical specification. But before my team finished, the Business Manager handed me his own spec. A spec ready to be executed. The document was generated with AI assistance and it was impressive — fifty pages long, detailed feature breakdown, implementation timeline, cost projections. Everything looked professional. The AI had done exactly what it was asked to do. I read the whole document and noticed a problem. Not with the quality of the document but with the perspective that shaped it. The spec called for a manual Excel-based workflow with several manual steps and validations in-between. All seemed clean and manageable, matching the Business Manager's mental model of how that business workflow should work. When I checked the spec my team was working on using the same AI assistance tools, I noticed they had produced something completely different: automated data ingestion, real-time dashboards, API integrations with existing systems. Both specs addressed the same business need. Both were technically sound. Both could be built in roughly the same timeframe. But they were fundamentally different architectures, shaped by fundamentally different perspectives on how work should happen. The Business Manager's version was optimized for control and visibility — he could see every step, every piece of information and approve everything manually at any stage. The technical lead's version optimized for efficiency and scale — minimal manual intervention, automated error handling, designed to handle 10x the current volume without breaking. Neither person was wrong. But the AI amplifi

If you’ve spent any time recently writing detailed product requirement documents or meticulously...

Suppose leadership rewards teams for increasing the percentage of “AI-assisted pull requests.” The dashboard rises. Did productivity improve, or did people learn which box to tick? Before launching that metric, I would run a consequence-mapping session: Intended behavior Plausible adaptation Counter-metric try useful assistance label trivial PRs as assisted retained task outcome ship faster split work into tiny PRs lead time per task share adoption avoid difficult non-AI work task-mix distribution accept suggestions reduce review scrutiny rollback and defect rate The metric card should make disagreement possible: name : ai_assisted_pr_share purpose : detect workflow adoption, not productivity owner : developer-experience known_game : self-label inflation counter_metrics : [ task_mix , review_minutes , rollback_rate ] review_date : 2026-08-19 retire_when : classification cannot be audited Then interview both high and low scorers without treating the score as performance. Ask what work disappeared, what new verification appeared, and what behavior the dashboard encouraged. Include an anonymous channel: a metric cannot reveal pressure if challenging it carries career risk. The SPACE framework argues that developer productivity cannot be captured by one dimension. That is especially relevant when AI telemetry is easy to count but verification and rework are harder to observe. My launch gate is not “the metric is accurate.” It is: teams can inspect its definition, challenge its interpretation, and show where it changes behavior. If the counter-metrics diverge, pause incentives before refining the chart. What behavior would your current AI dashboard accidentally reward?

An accepted AI suggestion is an event, not a durable outcome. If the code is rewritten tomorrow, acceptance rate still calls it a success. For an adoption review, I would connect three timestamps: suggestion : accepted_at : 2026-07-19T09:00:00Z repository : api task_type : test change : retained_lines_24h : 31 rewritten_lines_24h : 9 reverted_at : null review : human_minutes : 12 incident_link : null Then report a funnel rather than one flattering percentage: shown → accepted → merged → retained_24h → retained_14d A useful unit is cost per retained task : (tool cost + review labor + rework labor) / retained tasks “Retained” needs a written contract. For example: the change remains merged after 14 days, passes required checks, and has not caused a linked rollback. Line survival alone is weak because formatting and refactoring can change lines without rejecting the solution. Segment the result by task type and repository. Boilerplate tests and unfamiliar security changes should not be blended into one portfolio average. Also publish counter-metrics: review time, escaped defects, rollback rate, and developer-reported interruption. GitHub documents available fields and limitations in its Copilot metrics API . Those product metrics can be inputs, but the retained-task join belongs to the adopting organization and should be versioned like any other analytics contract. My pilot gate would be simple: expand only if retained-task cost beats the existing workflow without worsening rollback rate. Otherwise, change the workflow before buying more seats. Record the baseline before enabling the tool, and keep one comparable task cohort outside the rollout; without that counterfactual, a rising retention rate may only reflect easier work entering the sample. What retention window would make an accepted change meaningful for your team?

By default, the Docker container utilizes an SQLite database, but it can be configured to use PostgreSQL or MySQL by setting the DATABASE_URL environment variable. Docker Compose configurations are also provided, enabling deployment with custom domains and automatic SSL certificate issuance via Caddy. Pro features, available through commercial offerings, extend the platform's capabilities to meet business needs. These include compa

OpenAI's July 14 guidance for managing AI investments recommends five moves: improve visibility into usage and spend, evaluate efficiency by outcome ROI, govern advanced workflows before scaling, fund workflows that compound, and match capacity to proven demand. Primary source: OpenAI, “How to manage AI investments in the agentic era” . The hard part is the denominator. “This agent used $800” says little. “This workflow cost $14 per accepted reconciliation, including review and rework” can support a decision. Here is a one-page ledger I would require for an agent pilot. Define one accepted outcome Do not start with tokens, seats, or tasks launched. Define the business state that counts after review. workflow : vendor-invoice-reconciliation accepted_outcome : " invoice matched, exceptions reviewed, result posted" owner : finance-ops pilot_window_days : 21 minimum_sample : 100 invoices quality_gate : false_postings : 0 exception_recall : " >= 0.98" reviewer_minutes_p50 : " <= 3" A generated draft is not an outcome if a person must rebuild it. An agent run is not successful if its result never enters the system of record. Capture the complete cost AI cost + orchestration and observability + human review + rework + incident handling + allocated implementation cost = total workflow cost Use a table with declared variables: Variable Meaning Example only C_model model and tool-call spend $600 C_platform workflow infrastructure $200 H_review reviewer hours 35 R_hour loaded reviewer rate $45 C_build pilot build cost allocated to window $2,000 N_accept accepted outcomes 850 total = C_model + C_platform + H_review * R_hour + C_build cost_per_accepted_outcome = total / N_accept With the illustrative numbers, total cost is $4,375 , or about $5.15 per accepted outcome. These are not benchmark claims; replace every value with measured data. Compare against the real baseline The baseline must use the same unit and quality gate: Metric Manual baseline Agent pilot attempted invoices

Last week an AI-generated GPU kernel ran 18.71× faster than an optimized PyTorch baseline. The model—Fable 5—didn't just edge past the human implementation. It lapped it. Claude Opus 4.8 reached 14.4×. GLM-5.2 hit 11.14×. GPT-5.5 managed 4.34×. Fable's kernel was in a different tier entirely. The exciting read: AI is starting to improve the low-level machinery that makes AI itself cheaper and faster. Specialized performance work that once required rare expertise just got dramatically easier to explore. The uncomfortable read: what happens when the best implementation is also the one nobody on your team would have written—or can fully explain? That question is about to land on every engineering team that ships AI-generated code. The Benchmark Problem A benchmark shows the kernel ran fast under tested conditions. It doesn't show: How it behaves across different GPU hardware How it handles numerical edge cases What happens under months of production changes Whether it degrades gracefully when inputs shift The person who wrote it can't answer these questions either. The AI generated this code through a process that doesn't leave a reviewable chain of reasoning. There's no commit message that says "I chose this approach because X." So the reviewer's job just got harder—not easier. The Real Shift I've been watching this pattern across engineering teams this year. The argument is moving from "can AI generate working code?" to "can our org absorb generated code without breaking quality, morale, or judgment?" The GPU kernel story makes the tension concrete: One side says the code ran, it was measured, it won. Stop moving the goalposts. The other side says somebody still has to know where it can fail and take responsibility when it does. Both are right. AI can make implementation cheaper while making proof more expensive. Senior engineers may write less code but spend more time designing adversarial tests, checking assumptions, planning rollbacks, and deciding whether an impr

Design + Product Thinking: NYC’s Path to Reliable AI AI delivers value when it’s useful, trusted, and operational. For city services that affect millions, those qualities don’t happen by accident — they come from applying design thinking (who the service is for, how it’s used) together with product thinking (what outcome we’re trying to achieve and how we operate over time). This article explains why hiring designers and product managers matters for NYC’s digital and AI initiatives, summarizes the city’s PIT Crew program, and outlines how Flamelit applies outcome-focused delivery in the public sector. Why design and product roles matter Designers and product managers have distinct but complementary responsibilities that reduce common AI delivery failures: Designers (Design Thinking): center human needs, prototype user flows, and validate that interfaces and decision workflows are understandable and accessible. They surface usability and trust issues early, preventing technically accurate models from becoming unusable in practice. Product managers (Product Thinking): define the measurable outcomes, prioritize use cases, align stakeholders, and manage the lifecycle from discovery to ongoing operations. They ensure work is evaluated against mission impact, not just technical metrics. Together they prevent common failures: building technically impressive models that nobody trusts, deploying brittle systems without human review, or shipping features with unclear ownership that decay in production. PIT Crew and NYC hiring context NYC’s PIT Crew program is a city initiative designed to attract and staff product, engineering, and design talent for public service projects. It’s a practical recognition that public-sector digital transformation needs people skilled in user research, product management, and delivery.

Someone would ask a question in a public Slack channel. Every so often a couple of people would start to answer. Then the manager would step in, say what was going to happen, and the thread would go quiet. On its own, it looks like nothing. A decisive manager keeping things moving. But it was a team going quietly into debt, and the dead Slack thread was one of the interest payments. You already know tech debt. You cut a corner in the code to ship faster, and you pay interest on it later in bugs, slow changes, and the one file nobody wants to touch. Culture debt works the same way, except the corners you cut aren't in the code. They're in the norms, the expectations, and the relationships that decide how people actually work together. But tech debt is visible. You can see it, point at the file, write a ticket, argue about whether it's worth paying down. Culture debt is more dangerous because it gives you none of that. You don't watch it accruing. You see the symptoms, and by the time they show up, the debt has already compounded. Let me tell you how a team I joined got there. The reward was volume. The only thing that reliably got praised was pushing a lot of code. The manager was open about it...their whole framing of the job was being able to out ship anyone on the team. Everyone else stayed quiet. Nobody ever stood up and argued against quality. If you'd asked, the manager would have agreed that testing mattered and that quality mattered. Those things just never got prioritized. So over and over, what actually got rewarded (volume) quietly beat what everyone said they wanted. This didn't happen out loud. The reward silently won every time. You can guess what that bought. Planning went first, so features shipped in half finished states and got abandoned there. Testing basically didn't exist. We had a QA person, but things slipped through constantly. Bugs were everywhere. Plenty of features barely worked, and some just didn't. The human side hollowed out at the same

Most people assume better AI performance means a bigger bill. That assumption is quietly being proven wrong. The "Don't Touch It" Trap in AI Products There's a psychological pattern that shows up in almost every team running a live AI-powered product: once something works, nobody wants to mess with it. And honestly, that instinct makes sense. You've tuned your prompts, worked out the edge cases, trained your users, and finally gotten the thing stable. The idea of swapping out the underlying model - the engine of the whole operation - feels like pulling a thread that might unravel everything. So teams stay put. They watch new model releases come out, read the benchmark comparisons, and quietly decide it's not worth the risk. The phrase you hear most often is "if it ain't broke, don't fix it." The problem is that this logic made sense when model upgrades were expensive and disruptive. That's no longer the default reality. What's actually happening now is that AI providers are competing hard on price-per-token while simultaneously improving quality. That combination - better output, lower cost - breaks the old mental model most product people are still operating with. What a Model Migration Actually Involves Let's be clear: switching AI models isn't a one-click operation. But it's also not the months-long project many teams imagine it to be. At its core, a model migration for an AI agent involves three things: re-evaluating your prompts (because different models respond differently to the same instructions), running parallel tests to compare output quality on your real use cases, and updating any API parameters that differ between versions. That's the actual work. For most small-to-medium deployments, that's days of effort, not weeks. The bigger shift is in how you think about model versions. Rather than treating the model as permanent infrastructure, it helps to think of it more like a dependency in your software stack - something you update deliberately, test careful

Most organisations approach a Dynamics 365 Customer Engagement implementation with one question at the top of their agenda: How long will this take? It is a reasonable question, and one that deserves a precise, well-considered answer rather than a vague estimate designed to win the deal. The reality is that Dynamics 365 CE implementation timelines vary significantly, shaped by factors that are unique to each organisation: business complexity, data readiness, customisation depth, integration requirements, and internal stakeholder availability. This guide provides a structured, phase-by-phase breakdown of what a Dynamics 365 CE implementation actually involves, realistic timeline benchmarks by business size and industry, and the critical factors that either accelerate or delay your go-live date. Why there is no one-size-fits-all timeline for Dynamics 365 CE implementation Why There Is No Single Answer to the Timeline Question Dynamics 365 Customer Engagement is not a standalone application. It is a modular platform encompassing Sales, Customer Service, Field Service, and Marketing, each carrying its own configuration requirements, data dependencies, and user adoption considerations. A professional services firm deploying D365 Sales for a 25-person team operates in an entirely different context than a multi-national enterprise rolling out Customer Service and Field Service across three regions. Treating these as comparable projects, with comparable timelines, is where expectations first go wrong. As a reference framework, Dynamics 365 CE implementations broadly fall into three tiers: Implementation Scope Basic deployment, minimal customization :- 6 – 12 weeks Mid-market with integrations and moderate configuration :- 3 – 6 months Enterprise, multi-module or multi-region rollout :- 6 – 16 months These are informed benchmarks, not guarantees. What determines where your project lands within or beyond these ranges is examined in detail below. Core phases of a Microsoft Dyn

TL;DR Retailers process thousands of inventory transactions every second across physical stores, eCommerce platforms, warehouses, suppliers, and fulfillment centers. Yet many inventory systems still rely on scheduled synchronization, causing stock levels to become outdated within minutes. The result is overselling, delayed replenishment, inaccurate inventory visibility, and avoidable stockouts. Apache Kafka enables real-time inventory management by treating every inventory movement as an event that is streamed the moment it occurs. Sales, returns, warehouse transfers, supplier deliveries, and IoT sensor updates are continuously processed to maintain a consistent inventory view across all retail systems. This event-driven approach helps retailers improve inventory accuracy, automate replenishment, detect stockouts before they occur, and respond to changing demand in near real time. In this guide, you'll learn how Apache Kafka powers real-time inventory management, explore a production-ready reference architecture, understand how inventory events are processed across retail systems, and discover implementation best practices for building scalable, resilient inventory streaming applications. Introduction Retail inventory management has evolved far beyond tracking products on warehouse shelves. Today's retailers operate across physical stores, eCommerce platforms, online marketplaces, distribution centers, and supplier networks, where inventory levels change continuously throughout the day. Every sale, return, warehouse transfer, supplier delivery, and inventory adjustment impacts product availability, making accurate inventory visibility essential for delivering a seamless customer experience. However, many retailers still rely on scheduled synchronization between Point-of-Sale (POS) systems, Warehouse Management Systems (WMS), Enterprise Resource Planning (ERP) platforms, and online storefronts. While these systems perform different functions, they all depend on accur

WordPress 7.0, released on May 20, 2026, includes new AI infrastructure, a redesigned admin interface, and updated design tools. Key features comprise an AI Client, Abilities API, and Command Palette, alongside increased PHP requirements. Community feedback is mixed, particularly regarding AI integration. Developers are advised to consult the official documentation for upgrade guidance. By Daniel Curtis

The Smartest AI Workflow I Have Ever Seen Ran on Three Pages of Prompt Project managers are quietly building their own AI chief of staff. The duct tape is the interesting part. A few weeks ago I was talking with a project manager who runs large industrial projects. Real ones, with safety officers and subcontractors and go-live dates that cost serious money when they slip. Somewhere in the conversation he mentioned, almost apologetically, a side project of his. Every week, he feeds an AI model his project charter, the project plan, the risk register, the action tracker, and the last six weeks of status reports. Then he adds the current week's meeting notes and any relevant emails. On top of all that sits a prompt he has iterated on for months. It covers three A4 pages in font size 10. Out the other end comes a list of specific open topics he needs to chase down before writing his end-of-week status report. He has a second prompt that helps him prepare sharp questions for the weekly team meeting. A third one, about 200 lines, assembles everything and drafts the status report itself. He even runs scenario checks: the safety officer found discrepancies during vehicle inspections, the subcontractor says compliance takes two extra weeks, does this move the critical path and the go-live date? He called it manual and clunky. I think it is one of the most sophisticated AI workflows I have ever seen a working professional build, in any field. And I have been building software for a long time. But he was right about the clunky part. And the reason it is clunky tells you almost everything about where AI in project work is actually stuck. The analysis was never the hard part Here is the thing he said that stuck with me, close to verbatim: The AI is good at analysing lots of text sources. The challenge is to obtain all the information, and the effort to write it down comprehensively. Read that again. The intelligence is not the bottleneck. The bottleneck is assembly. Every single
