This is a submission for DEV's Summer Bug Smash: Clear the Lineup , powered by Sentry . Project Overview I built LeakLens Control Room to keep AI away from the financial math. Python calculates every dollar. The optional model explains the evidence. A human decides whether to act. LeakLens is a live, functional restaurant margin-review application built with Python, SQLite, HTML, CSS, and JavaScript. It uses synthetic data in the public demo. The optional application narrative provider defaults to GPT-5.6, but every rate, threshold, ranking, and dollar scenario comes from deterministic code. Then a date string proved that deterministic code can still lie. I had let a raw CSV field decide which operating day counted as "current." Bug Fix or Performance Improvement The symptom LeakLens groups channel metrics by date, sorts those dates, and analyzes the last one against prior days. That works when every input is canonical ISO data such as 2026-07-09 . The loader only checked that the date field was not blank. This input slipped through: metrics = [ DailyMetric ( " 2026-7-9 " , " direct " , 500 , 250 , 0 , 0 , 125 ), DailyMetric ( " 2026-07-10 " , " direct " , 1000 , 50 , 0 , 0 , 250 ), ] July 10 is later than July 9. Python's string ordering sees something else: sorted ([ " 2026-07-10 " , " 2026-7-9 " ]) # ['2026-07-10', '2026-7-9'] LeakLens selected the final string, 2026-7-9 , as the current day. That mistake spread through the report: expected current date: 2026-07-10 actual current date: 2026-7-9 actual gross sales: 500.00 sales-loss scenario: 500.00 discount scenario: 225.00 The input had not shown a current sales collapse or discount leak. The analyzer compared the days backward and produced $725 of false scenario impact from synthetic data. For a restaurant operator, this is worse than a visible crash. A crash asks for attention. A plausible financial report can send someone to audit the wrong promotion, question the wrong manager, or change a schedule that was

Python quickstart: nutrition data in 10 lines You can search Dietly's public nutrition catalog with one GET request to https://api.getdietly.com/search . The response is a JSON array of foods, not an object with a results property. Install requests , run the example below, and you have a working nutrition lookup. The rest of this page turns that single call into something dependable: a client class, correct field handling, and retries that respect the rate limit. Make your first request The only required parameter is q (minimum two characters). Use limit to cap results between 1 and 50. Ten is plenty while you explore. import requests r = requests . get ( " https://api.getdietly.com/search " , params = { " q " : " greek yogurt " , " limit " : 5 }, timeout = 10 ) r . raise_for_status () foods = r . json () for food in foods : print ( food [ " name " ], food . get ( " protein_g " )) Understand the fields you get back Each result is a flat object. Nutrient values are per 100 g of the product unless noted, and any nutrient can be null when the source label did not list it. Treat null as unknown, never as zero. Field Meaning id Stable Dietly food ID, used for direct lookups name , brand Product name and brand when known calories_kcal Energy per 100 g protein_g , fat_g , carbs_g Macronutrients per 100 g fiber_g , sugar_g , saturated_fat_g , sodium_mg Detail nutrients per 100 g, often null serving_size_g , serving_desc One serving in grams and its label wording, when provided source , confidence Where the record came from and how sure Dietly is static_url Path to the food's page on getdietly.com, when one exists To convert a per-100 g value to a portion, multiply by grams and divide by 100. For a 150 g serving of a food with 10 g protein per 100 g, that is 10 * 150 / 100 = 15 g. Read the result defensively An empty search is [] , which is a normal outcome rather than an error. Guard for it, and keep null nutrients as null in your own model. food = foods [ 0 ] if foods else

Most portfolios have a boring "About Me" paragraph. I replaced mine with something you can talk to — an AI terminal that answers questions about me, pulls my live GitHub activity, and remembers the conversation. You can try it right now on my portfolio: rehbarkhan.in . I'm Rehbar Khan , a Full Stack & Gen-AI developer, and in this post I'll break down exactly how it works — the RAG pipeline, the LangGraph agent, the memory layer, and how I wired in real GitHub data with MCP. No fluff, just the architecture. The problem I wanted a portfolio assistant that could: Answer questions about my background accurately — no hallucinated jobs or fake projects. Fetch live data (my latest GitHub activity), not a stale snapshot. Remember the conversation across messages. Stream responses token-by-token like a real terminal. That rules out "just prompt an LLM." You need retrieval for grounding, tools for live data, and state for memory. Here's the stack I landed on. Architecture at a glance Next.js 16 chat UI ──► FastAPI (streaming) ──► LangGraph agent ├── RAG retriever → pgvector (Neon Postgres) ├── GitHub MCP tool → live GitHub data └── Redis checkpointer → conversation memory Frontend: Next.js 16 (App Router, TypeScript) — a streaming terminal UI. Backend: FastAPI with streaming responses. Orchestration: LangGraph ( StateGraph , ToolNode , tools_condition ). LLM: OpenAI gpt-4o-mini . Retrieval: text-embedding-3-small → pgvector on Neon Postgres. Memory: Redis checkpointer for per-session history. Live data: GitHub via the Model Context Protocol (MCP) . 1. The RAG pipeline Everything the bot knows about me lives in a single reference.txt . I chunk it, embed it, and store it in Postgres with pgvector: from langchain_text_splitters import RecursiveCharacterTextSplitter from langchain_openai import OpenAIEmbeddings from langchain_postgres import PGVector splitter = RecursiveCharacterTextSplitter ( chunk_size = 500 , chunk_overlap = 80 ) chunks = splitter . split_text ( open ( " refe

Every model card says "multimodal". Then you hand the model a real video file and discover what that means in practice: ChatGPT reads the subtitle track, Claude doesn't accept video files at all. The model narrates a video it mostly never saw. I unpack viral videos daily for my own content work, so I couldn't route around this. I built a small tool instead. The mechanism claude-real-video converts a video into three things an LLM can genuinely read: Scene-aware sampled frames — ffmpeg scene scores decide where to sample, so you get a frame when the picture changes, not every N seconds. An --adaptive flag handles slow deformations (a real user bug report: fixed thresholds missed squash/stretch morphs entirely). A timestamped transcript — whisper by default; if faster-whisper is installed it runs in-process and several times faster, with automatic fallback. One MANIFEST timeline — frames and transcript merged into a single file, so the model follows the video in order instead of guessing from fragments. A --text-anchors flag force-samples frames at subtitle cues so on-screen text never falls between frames. Then you point any LLM at the output folder — Claude, GPT, Gemini, or a local model. No API of mine in the middle, everything runs on your machine. Usage pip install claude-real-video crv "video.mp4" -o out Honest limitations Not real-time — a 90-second video takes about 1–2 minutes all-in on an M-series Mac. Frame sampling can still miss motion between frames; the flags above patch the worst cases, both born from real GitHub issues. It's MIT, currently at 1,731 stars with ~8k installs last month, which taught me the problem was never just mine: https://github.com/HUANGCHIHHUNGLeo/claude-real-video

How machine learning supports aircraft maintenance using operational data. Key Takeaways Predictive maintenance estimates component health before failure. Data quality determines model performance. Explainable models support maintenance decisions. Human review remains part of every maintenance action. Model performance requires continuous validation. Introduction Aircraft produce large volumes of operational data. Machine learning converts this data into maintenance support inspection planning and fault detection. What Is Predictive Maintenance? Predictive maintenance estimates the condition of aircraft components using historical and real-time data. The goal is to identify early signs of degradation before a failure affects operations. Traditional maintenance often follows fixed inspection intervals. Data-driven maintenance adds condition-based recommendations using operational evidence. Data Sources Model quality depends on reliable data. Common sources include: Engine sensor readings Flight data recorder information Maintenance records Aircraft utilization history Environmental conditions Component replacement history Incomplete or inaccurate data reduces prediction accuracy. Machine Learning Workflow A typical workflow includes: Collect operational and maintenance data. Remove errors and missing values. Create features from sensor measurements. Train the prediction model. Validate performance using unseen data. Monitor prediction accuracy after deployment. Retrain the model as new data becomes available. Model Selection Different problems require different algorithms. Common choices include: Random Forest XGBoost LightGBM Support Vector Machine Long Short-Term Memory (LSTM) Transformer-based time-series models Model selection depends on the prediction task, dataset size, and operational requirements. Engineering Challenges Data Quality Sensor failures, missing records, and inconsistent maintenance logs reduce model reliability. Class Imbalance Aircraft failures

In today's world where websites and web applications play a very important role in businesses, choosing the right tool for developing a project is of great importance. Developers usually use frameworks to build websites faster, more securely, and more professionally. One of the most powerful and popular web development frameworks is Django . Django is a powerful and open-source web framework built with the Python programming language that allows developers to create complex and professional websites and web applications in a short amount of time. From simple websites to large systems, online stores, social networks, admin panels, and professional APIs — all can be developed with Django . In this article, we will thoroughly examine what Django is, why it has become popular, what its use cases are, and why many developers and large companies use it. What is a Framework? Before we get to know Django , it's better to understand the concept of a framework. A framework is a collection of pre-built tools, libraries, and rules that help developers build software faster and with better structure. In the past, developers had to create many features from scratch; for example: User login system Database connection Request management Application security Page structure File management But by using a framework, many of these capabilities are already prepared, and the developer can focus on the core logic of the project. Simply put, a framework is like a ready-made skeleton for building software that increases the speed and quality of development. What is Django? Django is a server-side (backend) web development framework written in Python . This framework is designed for building web applications and provides developers with many features by default. The main goal of Django is to make web development faster, more secure, more organized, and more scalable. Django's official slogan: The web framework for perfectionists with deadlines This slogan indicates that Django was built for

Every founder I know has burned a week building an investor list: digging through Crunchbase profiles tab by tab, copying partner names into a spreadsheet that is stale before the seed round closes. The data you want is simple, firms plus focus plus contacts, and it is weirdly hard to get in bulk. The shortcut I use now is the Startup Investors Data Scraper on Apify, a queryable investor database of 10,469 firms that returns filtered JSON in one call. Disclosure: the Apify links in this post are affiliate links. If you run the Actor, I may earn a referral commission at no extra cost to you. Is there a public API for investor data? Not really. The big commercial databases keep their APIs behind sales calls and paid plans sized for funds, not founders. Free sources are scattered lists and shared spreadsheets with no filters and no freshness guarantees. This Actor takes a different shape: a curated database of 10,469 investment firms (as of December 2025) that you query like an API, filtering by firm type, sector, stage, and country, and paying only for the records you pull. What the investor database API returns The investor database API returns one JSON record per firm: name, type, description, location, website, social links, assets under management, stages, and sector focus, with partner contacts when you ask for them. Field Example Notes firm_name Acme Ventures With firm_description alongside firm_type_name Venture Capital Investor One of 17 firm types firm_country Germany Plus firm_city and firm_state firm_website https://acme.vc Also firm_linkedin_url , crunchbase_url , twitter_url firm_aum $250M Assets under management when known investor_contacts [{ "job_title": "Partner", ... }] Names, titles, LinkedIn URLs, emails when available, and check sizes, with Include_Contacts on Who this is for Founders building a raise pipeline, sales teams selling into VC and PE back offices, and analysts mapping which firms fund a sector.

Day 17. OCR on banking apps is unreliable. I built a verification layer that double-checks every number. Day 16 was a milestone: multi-app workflows. The agent copied my bank balance and sent it to Mom on WhatsApp. Three apps. One task. But behind that success was an uncomfortable truth: the agent misreads numbers about 20% of the time. For a message to Mom, that's a typo. For a financial transaction, that's a disaster. Today, I built the fix. The Problem Banking apps scored F on my accessibility audit. No UI labels. No content descriptions. The agent has to rely entirely on OCR to read anything on screen. And banking apps have terrible OCR conditions: Small, condensed fonts for account numbers and balances Low contrast (grey text on slightly darker grey backgrounds) Currency symbols (₦, $, £) that OCR often confuses with numbers Commas in large numbers that OCR sometimes reads as decimals The result? A balance of "₦15,000" sometimes gets read as "₦15.000" or "₦15,00" or "₦15000." One missing digit. One wrong decimal. And the entire task is compromised. The Fix: Numeric Verification Layer I built a verification step specifically for financial data. Before any number gets stored in task memory, it goes through three checks. Check 1: Format Validation The extracted text must match a valid currency format. It must contain a currency symbol (₦, $, £, €) followed by digits, optionally with commas and a decimal point. Anything that doesn't match this pattern is rejected immediately. Check 2: Double-Read Confirmation The agent reads the same number twice—two separate screenshots, two separate OCR passes. If both readings match exactly, the number is accepted. If they differ, the agent reads a third time. If two out of three match, that value wins. If all three differ, the task is aborted with an error message. Check 3: Range Validation The extracted number must fall within a reasonable range. A bank balance of "₦0" or "₦999,999,999,999" is probably an OCR error. The agent

A few months ago, I noticed something interesting about Bluesky. The people who were growing weren't necessarily posting the most brilliant content. They were simply consistent. They showed up every day, joined conversations, experimented with ideas, and stayed visible. I wanted to do the same. The problem was that I also had code to write, bugs to fix, blog posts to publish, and projects to maintain. Opening Bluesky every couple of hours just to post something or reply to notifications quickly became another distraction. I knew I needed automation. Not because I wanted to spam the platform, but because I wanted consistency without sacrificing my development time. The obvious solution would have been renting a VPS or deploying another cloud service. But honestly, I didn't want another monthly bill. I started asking myself a different question: Could I build a Bluesky AI bot that runs entirely on free services? That question eventually led me to GitHub Actions. Why GitHub Actions? Most automation tutorials immediately recommend a VPS, Docker container, or cloud function. Those work well. But for a personal automation project, they felt like overkill. GitHub Actions already gives developers something incredibly useful: Scheduled workflows Secure secret storage Python support Free minutes for public repositories Instead of paying for infrastructure, I could let GitHub execute my script several times a day. No servers. No maintenance. No SSH. No uptime monitoring. Just commit the code and let GitHub handle the rest. The Architecture The entire workflow is surprisingly small. GitHub Actions (Cron Schedule) │ ▼ Python Script │ Generates Prompt │ ▼ Gemini API │ Returns AI Post │ ▼ Bluesky API │ ▼ Publish Content Every scheduled run follows the same sequence. GitHub wakes up the workflow. The Python script builds a prompt. Gemini generates a post. The script authenticates using a Bluesky App Password. The post gets published automatically. After that, GitHub shuts everythin

footnote-mcp is a Python MCP server installable via pip, Docker, or pipx. No API keys required — it falls back to scraped Bing + DuckDuckGo search and automatic headless Chromium for JavaScript-heavy pages. The Verification Pipeline The core tool is evidence_entailment . It takes a claim and a source text, and returns whether the claim is supported, unsupported, or contradicted. The heuristic backend extracts numeric and named-entity tokens from both the claim and source, then checks for exact matches and contradictions. On its design domain — numeric and factual data claims — it achieves 100% accuracy on a labeled benchmark set. For semantic cases (negation, paraphrase), the ollama backend uses a local LLM as a judge. Three tools build on this: corroborate_claim triangulates a claim across multiple sources, locate_claim_span finds the exact supporting sentence with character offsets, and build_research_debug_report produces a compact report of queries, URLs, and verification gaps. The Fetch Ladder web_read fetches pages through a 5-tier escalation ladder: HTTP (curl_cffi) to rotating proxy to headless Chromium to Chromium through proxy to hosted scrape API (Firecrawl/ScrapingBee). A block/quality detector decides when to escalate, and per-domain rate limiting, circuit breakers, and negative cache keep it polite. Search Backends web_search supports Tavily, Brave, Google, or scraped Bing + DuckDuckGo as fallback. Pass semantic: true to reorder results by meaning using local Ollama embeddings. Structured Data and Browser Tools Beyond text, the server handles tables, CSV/XLSX/PDF/JSON, date validation, unit resolution, and time series reconciliation. For JavaScript-heavy pages, 10 browser tools let you drive a headless Chromium session. When generic parsers fail, the server can synthesize sandboxed extraction code through a controlled recipe system. Benchmark Results The heuristic backend achieves 100% accuracy on numeric and factual data claims (n=15). Overall accurac

When I built the MCP server for this project — it combines GitHub and DEV.to into a set of tools an agent can call — I had a decision to make before writing a single tool: talk to the low-level MCP protocol directly, or use FastMCP 's decorator API. I've seen a few "your first MCP server" writeups lately walk through the low-level path because it's more "honest" about what MCP actually is under the hood — JSON-RPC over stdio, a capabilities handshake, typed request/response schemas. That's true, and it's a reasonable thing to want to understand. But I want to write about the other side: what it actually costs you in practice once you have more than one or two tools, because I went through both and the difference showed up fast. what the low-level path actually asks you to write Strip away the decorator and MCP is a JSON-RPC server. For every tool you add, you're responsible for: Registering the tool's name, description, and a JSON Schema for its inputs in a list_tools handler Writing a call_tool dispatcher that matches on tool name and unpacks arguments by hand Serializing the return value into the TextContent / ImageContent wrapper types MCP expects Keeping the schema you wrote in step 1 in sync with the arguments you actually read in step 2, by hand, forever None of that is hard in isolation. The problem is it's boilerplate that scales linearly with tool count and has zero connection to the actual logic of the tool. My server has 8 tools. Hand-rolled, that's 8 schema blocks plus a dispatcher if/elif chain plus 8 response-wrapping calls, all of which exist purely to satisfy the protocol, not to do anything a GitHub or DEV.to API call needs. what it looks like with FastMCP Here's an actual tool from server.py , unedited: @mcp.tool () def get_repo_stats ( repo : str ) -> dict : """ Get stars, forks, watchers, open issues for enjoykumawat/<repo>.

variant-confidence v0.1.0: a calibrated confidence layer for variant-effect pathogenicity scores State-of-the-art variant-effect models are accurate in cross-validation but their scores are poorly calibrated on temporal data. variant-confidence adds an auditable calibration layer on top of existing predictors — it does not train a new model. The problem: accuracy is not trust Protein variant-effect predictors (AlphaMissense, ESM-1v, EVE) report pathogenicity scores, but a clinician or researcher needs to know how much to trust the number , not just its rank. The gap is calibration, not accuracy: AnnotateMissense (2026) reports MCC 0.94 in cross-validation, dropping to 0.76 on temporal ClinVar, accuracy 0.8798. A raw score near 0.9 may not mean 90% probability. Acting on an uncalibrated score is a risk. What it does variant-confidence wraps an existing predictor's score and produces a calibrated, uncertainty-aware output: Probability calibration (AC1): Platt scaling or isotonic regression over a separate holdout. Selectable, not hardcoded. Conformal prediction (AC1b): coverage 1−α intervals, split or Mondrian by gene. ECE (AC2, AC9): Expected Calibration Error reported before/after calibration, with bootstrap CI and per-bin counts. Bins with too few samples are flagged as low-reliability. Leakage-free split (AC3): temporal split by ClinVar release date with gene isolation — the same gene never appears in both train and test. This is unit-tested. Missing-score handling (AC4): works with AlphaMissense or ESM-1v alone; emits an explicit warning instead of failing silently. Non-deceptive reporting (AC7): every result includes interval/ECE + method + threshold, never a bare calibrated score.

Tackling idioms, cultural references, and ambiguous phrases in AI-powered book translation. At LectuLibre, we’ve been working on an AI-powered book translation service. One of the toughest challenges we ran into wasn’t the straightforward sentences — it was the non-standard text: idioms, metaphors, cultural references, and ambiguous phrases that machine translation consistently butchers. We needed a way to not only translate these correctly but also let users verify and edit the translations, because in literary works, getting them wrong breaks the entire reading experience. That’s how we built our 非标准文本翻译与含义确认 (non‑standard text translation and meaning confirmation) feature. It’s a pipeline that detects tricky sentences, proposes a contextual translation with a full meaning explanation, and gives users a final say. Here’s the engineering story, warts and all. The Problem Standard LLM translation does an impressive job on factual, literal text. But when a book says “it’s raining cats and dogs” it could be rendered as “raining animals” in the target language, which is either brilliant or absurd depending on context. Idioms often carry cultural weight that a simple word‑for‑word translation misplaces. Additionally, metaphors and ambiguous phrases can have multiple valid interpretations. For a translator, understanding the intent behind the phrase is half the work. We wanted a system that: Automatically identifies sentences containing non‑standard language. Generates a translation that preserves the original meaning rather than just the literal words. Provides a plain‑language explanation of what the phrase actually means (e.g., “This is an English idiom meaning it’s raining heavily”), so the user can judge the translation’s accuracy. Allows the user to confirm, edit, or retranslate those segments. A book can easily run to hundreds of thousands of words, so cost and speed were critical. We couldn’t just throw everything at a single high‑end LLM and call it a day. Our A

Suspect-condition workflows are deceptively simple to prototype and surprisingly hard to make defensible . Anyone can flag "this member might have HCC X." Building a system whose output survives a RADV audit is a different problem. This is a walkthrough of the three stages and the engineering decisions that matter at each. Stage 1: Identify Identification is pattern detection over a member's clinical record — labs, medications, prior diagnoses, utilization. Model it as a set of rules or features that emit candidate HCCs: def identify_suspects ( member ): suspects = [] if member [ " labs " ]. get ( " a1c " , 0 ) >= 9.0 and " insulin " in member [ " meds " ]: suspects . append ({ " hcc " : " HCC38 " , " trigger " : " a1c>=9 + insulin " }) if member . get ( " egfr " ) and member [ " egfr " ] < 30 : suspects . append ({ " hcc " : " HCC326 " , " trigger " : " egfr<30 " }) return suspects The temptation is to maximize recall here — flag everything. Resist it. Every unvalidated suspect you generate is downstream work and downstream risk. Stage 2: Validate (the stage that actually matters) Validation attaches evidence to each suspect and scores its defensibility. This is the difference between a documentation opportunity and an audit liability. def validate ( suspect , member ): evidence = collect_evidence ( suspect [ " hcc " ], member ) # labs, rx, prior dx suspect [ " evidence " ] = evidence suspect [ " confidence " ] = score_evidence ( evidence ) suspect [ " defensible " ] = suspect [ " confidence " ] >= 0.7 return suspect Key design rule: a suspect with an empty evidence array should never reach a coder. Make that a hard gate, not a soft warning. Under CMS-HCC V28 and current audit posture, a captured-but-unsupported diagnosis can be extrapolated across a contract into a real clawback — so "defensible by default" is the right engineering stance. Stage 3: Capture Capture routes validated suspects to the right human with the evidence inline, so the clinician or coder can
