The Model Context Protocol team has promoted its Enterprise-Managed Authorisation extension to stable status, adding a centralised way for organisations to control access to MCP servers through their identity provider. The project states the aim is to replace per-server consent prompts with a zero-touch flow in which users sign in once and then access approved servers without further setup. By Matt Saunders

With a Real CI Automation Example Loop Engineering is suddenly everywhere, and honestly, I wanted to understand it properly instead of just repeating the buzzword. The simplest way I can explain Loop Engineering is this: it replaces me as the person constantly prompting the agent. Instead of me manually noticing a problem, deciding what it means, writing the next prompt, and pushing the process forward, I design a system that keeps moving on its own until it reaches the outcome I want. That is the whole point of Loop Engineering. I stop acting like the operator and start acting like the system designer. To make that idea concrete, I built a practical software engineering workflow around CI failures. Whenever a GitHub Actions CI run fails, the system automatically classifies the failure, creates a Jira bug for real issues, sends a Slack notification, and records the outcome so it does not process the same failure twice. What Loop Engineering actually means Early AI workflows were mostly linear. I would give a prompt, the model would return an answer, and if the answer was incomplete or wrong, I would jump back in and prompt again. That worked, but it kept me trapped inside the process. Loop Engineering changes that dynamic. I am no longer the person babysitting each step. I build an autonomous loop that can observe, decide, act, and persist state. The system keeps iterating until the task is done, without needing me to micromanage it. That distinction matters. In a normal prompt based workflow, the human is still the glue. In Loop Engineering, the human creates the machine, and the machine runs the loop. The five building blocks of Loop Engineering When I break down Loop Engineering, I think of it as five core building blocks working together. 1. Automations These are the event driven triggers that start the whole system. They are the heartbeat of the loop. Something happens, and the automation fires. Without this, nothing starts. 2. Skills Skills give the agent stru

📦 Code: github.com/USER/nvenc-vs-cpu-bench - replace before publishing TL;DR A GPU encodes faster than a CPU, but "faster" and "cheaper" are different claims. We'll build a small FFmpeg + VMAF harness that times software (libx264/SVT-AV1) against hardware (h264_nvenc/av1_nvenc), then plug the results into a dollars-per-encoded-minute formula so you find your break-even instead of trusting a benchmark blog. We're using FFmpeg 7.1.x (current stable line) and an NVIDIA GPU with NVENC. Same approach works for Intel QSV ( *_qsv ) and AMD AMF ( *_amf ) if you swap the encoder names. Why this isn't obvious NVENC is a fixed-function hardware block, not "the GPU doing x264 in parallel." It's extremely fast and barely touches the CPU, but it exposes fewer rate-control knobs and gives up a little compression efficiency versus a slow software preset. The gap has narrowed a lot, but it's still there at the quality-obsessed end. So the decision is per-job, and it comes down to one number: dollars per encoded minute = (instance $/hr) ÷ (minutes encoded/hr) . GPU instances cost more per hour but encode many streams in parallel, so the answer depends on whether you can keep the encoder saturated. Let's measure instead of argue. 1. Set up the encoders Three contenders. One representative source file (use real footage, not a synthetic clip). # software H.264, quality-leaning preset ffmpeg -y -i source.mp4 -c :v libx264 -preset slow -crf 21 -an out_cpu.mp4 # NVENC H.264, quality-tuned ffmpeg -y -hwaccel cuda -i source.mp4 -c :v h264_nvenc -preset p6 -tune hq \ -rc vbr -cq 23 -an out_gpu.mp4 # AV1: software (SVT-AV1) vs hardware (needs Ada / RTX 40+) ffmpeg -y -i source.mp4 -c :v libsvtav1 -preset 6 -crf 30 -an out_svtav1.mp4 ffmpeg -y -hwaccel cuda -i source.mp4 -c :v av1_nvenc -preset p5 -cq 30 -an out_av1nvenc.mp4 💡 Tip: -preset p1 (fastest) through -preset p7 (slowest/highest quality) for NVENC. p6 / p7 is where it competes on quality; p1 - p3 is where it competes on raw throughput.

TL;DR Converting HDR10 to SDR with a naive FFmpeg command gives you grey, washed-out video. The fix is tone mapping. We will detect HDR with ffprobe , run two working tone-map chains ( zscale on CPU, libplacebo on GPU) in FFmpeg 8.0, compare operators, and batch it. Test the commands on your own build before shipping. 📦 Code: github.com/USER/hdr-to-sdr, replace before publishing If you have ever run an HDR clip through your normal pipeline and gotten back something flat and foggy, this post is for you. The bug is that HDR and SDR are different color systems, and "just converting" reinterprets one as the other. We will use FFmpeg 8.0 "Huffman" (8.0.2 is current as of May 2026). Why naive conversion fails HDR10 SDR Transfer function PQ (SMPTE ST 2084) gamma 2.4 / BT.1886 Color primaries Rec.2020 (wide) BT.709 (narrow) Peak luminance ~1,000 to 4,000 nits ~100 nits A command that ends in -pix_fmt yuv420p with no tone mapping reads PQ-encoded, Rec.2020 values as if they were SDR. The gamut gets crushed with no intelligence and the brightness curve is misread. Hence the fog. 1. Detect whether a file is even HDR 🔍 Do not tone-map SDR files. Check first: # detect transfer characteristics and primaries ffprobe -v error -select_streams v:0 \ -show_entries stream = color_transfer,color_primaries,color_space \ -of default = noprint_wrappers = 1 input.mkv HDR10 content reports something like: color_space = bt2020nc color_transfer = smpte2084 color_primaries = bt2020 If color_transfer is smpte2084 (PQ) or arib-std-b67 (HLG), you have HDR and you need to tone-map. If it says bt709 , leave it alone. 2. The libplacebo path (GPU, my default) 🚀 libplacebo is the Vulkan-accelerated filter in FFmpeg 8.0. It follows the ITU tone-mapping recommendations and handles the color conversions internally, so the command is short: ffmpeg -i input.mkv \ -vf "libplacebo=tonemapping=bt.2390:colorspace=bt709:color_primaries=bt709:color_trc=bt709:format=yuv420p" \ -c :v libx264 -crf 20 -c :a copy \ ou

"It works on my test input" is the most dangerous sentence in on-device AI development. I typed that sentence - or some version of it - a dozen times while building Redacto, our on-device PII redaction app running Gemma 4 E2B on a Samsung Galaxy S25 Ultra. The model would redact a patient name from a clinical note, I would nod, and I would move on. Then I would hand the phone to a teammate, they would type a police report, and the model would redact the suspect description instead of the victim name. The problem is not the model. The problem is that manual spot-checking is not validation. You are testing a single input against your own expectations, with all the confirmation bias that entails. When you have five domain modes (HIPAA, Financial, Tactical, Journalism, Field Service), three difficulty levels, and two candidate models, you need something systematic. You need a benchmark suite. This post covers how I built one - from dataset curation to scoring methodology to on-device infrastructure - for a hackathon app running entirely on a phone. No cloud. No API calls. No data leaving the device. Why Not Use an Existing Framework? The LLM evaluation space has mature tools. EleutherAI's lm-eval-harness is the community standard for evaluating language models against academic benchmarks like MMLU, HellaSwag, and ARC. Stanford's HELM (Holistic Evaluation of Language Models) provides a multi-metric evaluation framework with standardized scenarios. Google's BIG-bench offers hundreds of tasks for probing specific capabilities. These frameworks are excellent for what they do. They are also completely wrong for this problem, for three reasons. First, they assume server-side inference. lm-eval-harness expects to call a model through an API or load it in PyTorch on a GPU server. Redacto's model runs on a Qualcomm Hexagon NPU inside a phone. There is no Python runtime, no HuggingFace tokenizer at evaluation time, no way to hook into the framework's inference loop. Second, their

The Problem Nobody Talks About Everyone's posting AI-generated videos — characters speaking with lip-sync, manga panels coming alive, virtual idols dancing. The pitch: "just describe what you want." I tried. For months. Here's what I got: Character's face morphed by frame 2 "Slowly looks up" became "violent head shake" Voice-over sounded like Google Translate Same prompt, 3 runs, 3 completely different results No idea what to include or how long the prompt should be Tutorials were either too vague ("be detailed") or too technical (parameter tuning from line 1). The real issue: video prompts are structurally different from text/image prompts. You need to simultaneously control visuals, motion, audio, camera, and consistency constraints — in the right order, at the right length. What I Found A Skill in the Model Studio official repo called happyhorse-prompt-studio . It doesn't teach you theory — it asks you questions and assembles the prompt for you . 4-phase flow: 1. Inspiration Menu Shows you 4 "flavors" of what HappyHorse can do: Flavor What it does A · Voiced Manga Drama Characters talk to each other, with voice + lip-sync B · Character Voice PV Single character self-introduction, 8-10 sec C · Manga Panel Motion Static manga panel starts breathing D · Virtual Idol MV Idol performance with choreography 2.

A month ago we added a card_token column to the users table so a background job could retry failed Pro charges. It lasted about two days. Storing card data in your own database drops you into PCI-DSS (the compliance standard that kicks in the moment card data touches your systems), so we pulled it and moved to Stripe-managed payment methods. Last week the charges started failing again. New Claude Code session, no memory of any of that. Its plan? Add a card_token column to users and retry. I don't really blame the agent. It had the context the first time and it was right. The problem is that context died when the session closed. That's the part I never see mentioned about building with agents: the code sticks around, the reasoning doesn't. People leave a trail without trying. A commit message, a PR comment, the Slack thread before it. Agents don't, and the prompt that explained everything is gone by morning. So I built Selvedge to hold onto the reasoning. What happened the second time Selvedge is a local MCP server the agent calls as it works. There's a four-line block in our CLAUDE.md that says, roughly: before you touch an entity, check if we've been here before. $ selvedge prior-attempts users.card_token users.card_token Prior attempt 28 days ago ( reverted after 2 days ) Reasoning Added to store card tokens for one-click retries. Outcome REVERTED — kept card data out of our own DB to stay clear of PCI-DSS scope ; moved to Stripe-managed methods. So it didn't add the column. It charged off_session against the saved Stripe PaymentMethod instead. Charge retried, no card data in our database, done. We paid for that lesson once. How it works The agent writes down why live, in the moment, from the same context that made the change. That's the whole trick. A lot of the "git blame for AI" tools take your diff afterward and ask a second model to explain it. That's a guess. It reads well, but you can't really build on it. Selvedge stores what the agent actually meant, in i

In Part 1 , we introduced the idea that meaningful product design isn't about adding more — it's about knowing what to remove. Now let's examine this principle through a specific lens: meditation and mindfulness products. The Paradox of "More Mindfulness" Walk through any app store's health & wellness category and you'll find a strange contradiction: apps that promise to reduce your mental clutter by adding more things to your daily routine. Daily meditation streaks Guided breathing exercises (14 varieties) Sleep stories narrated by celebrities Mood tracking with 47 emotion labels Community challenges, leaderboards, badges AI-generated personalized recommendations The message is clear: "To feel less overwhelmed, here are 12 more things to do every day." This isn't just ironic — it's counterproductive. The cognitive load of managing a wellness routine can itself become a source of stress. The Feature Ceiling I've been studying meditation products for the past few months, and a pattern emerges across the market: Product Core Feature Total Features After 2 Years Calm Guided meditation ~40+ (stories, music, masterclasses) Headspace Guided meditation ~35+ (focus music, move, sleep casts) Balance Personalized meditation ~15 (singles, plans, skills) The most interesting case is Balance, which has fewer features but higher per-session engagement. Users spend more time meditating, not more time navigating. This isn't accidental. There's a cognitive principle at work: decision fatigue applies to self-care too. Every additional feature is another decision the user has to make before they can simply be still . What OneZen Gets Right OneZen takes the subtraction principle to its logical endpoint. Instead of asking "What can we add?" the product asks "What can we remove while still delivering value?" The result is a meditation tool that doesn't feel like a tool at all. It feels like breathing room. Three design choices worth studying: 1. No onboarding questionnaire. Most apps ask

This post was originally published on MatrixTrak.com — the production reliability toolkit for trading bot operators and .NET engineers. Complete WebSocket auto-reconnect guide for trading bots. Implement automatic reconnection with exponential backoff, heartbeat ping-pong, message gap detection, and state recovery. WebSocket connections drop. Not maybe. Definitely. Exchanges reset connections every 24 hours. Networks glitch. Load balancers rotate. HTTP proxies timeout. Your trading bot will experience disconnects. The question isn't whether you'll disconnect—it's whether your bot recovers correctly when you do. If you only do three things Implement automatic reconnection with exponential backoff and jitter. Track sequence numbers to detect missed messages. Always verify state via REST after reconnect. Never trust WebSocket alone. WebSocket Auto-Reconnect Quick Start If you just need a working auto-reconnect loop right now, here's the minimum viable implementation: class AutoReconnectWebSocket { private ws : WebSocket | null = null ; private reconnectAttempts = 0 ; private maxRetries = 10 ; private shouldReconnect = true ; async connect ( url : string ): Promise < void > { return new Promise (( resolve , reject ) => { this . ws = new WebSocket ( url ); this . ws . onopen = () => { this . reconnectAttempts = 0 ; resolve (); }; this . ws . onclose = ( event ) => { if ( this . shouldReconnect ) { const delay = this . backoff (); console . log ( `[AutoReconnect] Closed ${ event . code } . Reconnecting in ${ delay } ms` ); setTimeout (() => this . connect ( url ), delay ); } }; this . ws . onerror = () => { /* onclose fires next */ }; }); } private backoff (): number { const base = 1000 ; const max = 30000 ; const delay = Math . min ( base * Math . pow ( 2 , this . reconnectAttempts ++ ), max ); return delay + delay * 0.2 * ( Math . random () * 2 - 1 ); // +20% jitter } close (): void { this . shouldReconnect = false ; this . ws ?. close (); } } This handles the core auto

I fine-tuned Gemma 4 E2B. The adapter merged cleanly. The export to .litertlm completed without errors. I pushed the model to my phone, initialized the engine, and everything looked green. Then I tried to create a conversation and got this: Failed to apply template: unknown method: map has no method named get (in template:238) No model loading failure. No quantization error. The model initialized, the tokenizer loaded, and then the runtime choked on a Jinja template feature it does not support. This failure only surfaces when you actually try to run inference, not when you load the model. If you are demoing at a hackathon, this is the worst possible time to discover a compatibility issue. I hit this exact bug while building Redacto, a zero-trust PII redaction app that runs Gemma 4 E2B entirely on-device. This post walks through the full fine-tune-to-deploy pipeline: how to QLoRA a model on Colab, export it for LiteRT-LM, and avoid the undocumented template trap that will block your deployment. The Full Pipeline Here is what the fine-tune-to-deploy pipeline looks like end to end: HuggingFace base weights -> QLoRA fine-tune (Colab) -> Merge adapter into base -> Patch chat template <-- the step nobody tells you about -> Quantize + export to .litertlm -> Push to device Each stage has its own failure modes. The template patch step is the one that was undocumented at the time, and it is the one that will cost you hours if you do not know it exists. A note on framing before we dig in: this was an under-resourced fine-tune. I trained on 3,000 of the 400,000 samples in the ai4privacy/pii-masking-400k dataset for a single epoch, and the label format did not fully match what Redacto expected downstream. The point of this post is not the fine-tune's accuracy - it is the deployment mechanics I had to work through to get any fine-tuned model onto the device at all. Step 1: QLoRA Fine-Tuning on Colab QLoRA (Quantized Low-Rank Adaptation) lets you fine-tune a quantized model by tra

The obvious fix for "my projects all look similar" is a better README — more screenshots, clearer descriptions, maybe a comparison table. I considered that for about five minutes and decided it was still just a nicer list of links. What actually made a portfolio project feel different was making it something you could talk to instead of read. That's what MCP (Model Context Protocol) is built for — it's the standard that lets AI clients like Claude Desktop call external tools directly, not just process text. So I built a server that exposes my 9 projects as queryable tools instead of static entries. What is MCP, and why does it matter here Almost every AI-developer portfolio I've seen is a list of links. Mine now includes something you can actually talk to . Open Claude Desktop, connect my server, and ask "what has Ayush built with FastAPI?" — it doesn't guess from a cached README, it calls a real tool and answers from structured, live data. What I built A Python MCP server ( FastMCP , stdio transport) exposing five tools: list_projects — short summary of all 9 projects get_project_details(project_name) — full stack, GitHub link, demo URL for one project, fuzzy-matched by name search_projects_by_stack(technology) — "show me everything using Groq" or "LangGraph" or "React" get_flagship_project — the single best project to look at first get_resume_summary — background, target role, core stack The data itself lives in plain Python dictionaries right now — no database needed for something this size. Each tool is a thin function around that data, decorated with @mcp.tool() . @mcp.tool () def search_projects_by_stack ( technology : str ) -> list [ dict ]: """ Find all projects that use a given technology or tool. """ query = technology . lower (). strip () matches = [ { " name " : p [ " name " ], " stack " : p [ " stack " ], " github " : p [ " github " ]} for p in PROJECTS if any ( query in tech . lower () for tech in p [ " stack " ]) ] return matches or [{ " message " : f

Everyone talks about AI speeding up coding. Nobody talks about debugging AI-generated code. Last month, I spent three hours hunting down a bug in a 20-line function that an LLM wrote in thirty seconds. That's not a productivity gain—that's a productivity swap. You trade typing speed for debugging speed, and most of the time the trade is terrible. I've been using AI assistants for about a year now, mostly Claude and GPT-4, and I've noticed a pattern. The first version of any moderately complex piece of code always has at least one subtle mistake. Not syntax errors—those are easy. I'm talking about logical off-by-ones, missing edge cases, or completely hallucinated API calls. And the worst part? The AI writes the code with such confidence that you assume it's correct. You run it, it crashes, and you spend ten minutes thinking you misused the function before you finally look at the generated code with a suspicious eye. Let me show you a concrete example. I was building a small Node.js service that fetches data from a paginated REST API and merges the results. I asked the AI to write a function that handles pagination with a while loop and an offset parameter. Here's what it gave me: async function fetchAllPages ( baseUrl , limit = 100 ) { let offset = 0 ; let allData = []; let hasMore = true ; while ( hasMore ) { const response = await fetch ( ` ${ baseUrl } ?limit= ${ limit } &offset= ${ offset } ` ); const data = await response . json (); allData = allData . concat ( data . results ); hasMore = data . results . length === limit ; offset += limit ; } return allData ; } Looks clean, right? I pasted it in, ran my test, and got an infinite loop. The server returned a 400 error after a few requests, but the function kept going because response.ok was never checked. The AI assumed every call succeeds. I spent forty-five minutes debugging that—not because the bug was hard, but because I trusted the output. I added a try/catch and a status check, and then I found the real is

Before adopting DSPy, prove the LM program has a contract DSPy is easy to undersell. If you describe it as "a nicer way to write prompts", you will probably test the wrong thing. The better first test is this: can your language-model workflow be expressed as a small program with declared inputs, declared outputs, measurable examples, and an optimizer that is allowed to change prompts without changing the business boundary? That is the point where DSPy starts to make sense. The upstream README positions DSPy as a framework for programming, rather than prompting, foundation models. The current Doramagic project pack for stanfordnlp/dspy also points at the same starting command: pip install dspy . The package metadata I checked today declares name="dspy" , version 3.3.0b1 , and Python >=3.10,<3.15 . The GitHub API snapshot showed the repository was still active, with a push on 2026-07-05 and recent pull requests around empty evaluation sets, document formatting, and GEPA trace attribution. That activity is useful, but it is not the adoption proof. The proof is whether your own task can survive three separations. 1. Separate the task contract from the prompt In DSPy terms, the first artifact worth reading is not a clever prompt. It is the Signature. A Signature says what goes in and what must come out. A Module wraps that contract into something callable. An Adapter turns the contract into the provider-facing prompt format and parses the model response back into fields. That gives you a practical review question: Can the team name the output fields before anyone starts tuning wording? If the answer is no, DSPy will not rescue the workflow. You are still negotiating the task itself. The first pass should be a tiny contract: input text, retrieved context if needed, answer, citations, confidence, or whatever fields the product actually needs. Do not start with agents, tools, or multi-stage pipelines. 2. Separate compilation from runtime correctness DSPy optimizers can impr
