Google is going to give content creators and website owners a better idea of how people find their social media profiles and YouTube content through Search. With a new feature in the Google Search Console called "platform properties," Google says that you'll be able to "easily track which search terms lead people to your Instagram, […]

Most of the "AI for observability" work I see right now hands the language model the judgment. I think that's backwards. Feed it the alert, feed it some metrics, ask it what's wrong, what should be done, and let it make the judgement call. Based on my experience working with language models, I decided that inverting the process provides better results. The short version: in my alerting pipeline, the set of allowable classifications is fixed in deterministic Python, and the model has to pick from it. The LLM's only job is to turn a structured verdict into an easily digestible sentence. It never decides whether something is bad, how bad it is, or what category of problem it is. It narrates within a decision space the code has already locked down. TL;DR: Instead of letting an LLM decide what's wrong with an alert, I let deterministic Python make every operational decision and restrict the model to explaining the result in plain English. The code classifies, validates, and aggregates; the LLM only narrates. That keeps the data consistent, prevents hallucinated classifications, and ensures the monitoring pipeline continues working even if the model fails. The problem I run a small managed monitoring service. Alertmanager fires, a webhook lands, and historically that webhook produced a line like HighMemoryUsage on host web-vm, severity warning, which is accurate, but not terribly helpful. The person reading it still has to know what HighMemoryUsage implies, whether this host always runs hot, and whether to care. I wanted plain-English context attached to the alerts without altering the alert delivery process. The obvious move was to throw the whole alert at an LLM and ask it to explain. I tried that in the first iteration of this experiment, expecting it to be somewhat accurate, but not entirely reliable, and it did not disappoint, the model was confidently inconsistent. The same alert, fired three times, produced three different "root cause" categories. One run called a

Part 1: Solving GOP Structure and Compatibility Issues Operating a digital television network isn't just about keeping channels on air—it's about maintaining quality that viewers expect and troubleshooting issues before they escalate. When something goes wrong in live broadcasting, every second counts. But how do you quickly pinpoint whether the problem lies in encoder settings, transport stream structure, or temporal metadata? This is where specialized stream analysis tools become essential. In this series of articles, we'll walk through real-world scenarios that broadcast engineers face daily and show practical approaches to diagnosing and resolving them. When File Analysis Becomes Critical While live monitoring catches issues as they happen, file-based analysis is your diagnostic microscope. Here's the typical workflow: something breaks in production, engineers capture a few minutes of the problematic stream, and now they need to understand exactly what went wrong. File analyzers serve three primary purposes: Troubleshooting: Identifying the root cause of broadcast issues Encoder optimization: Fine-tuning compression settings Quality control: Validating compliance with standards and specifications Let's explore how this works in practice with actual tools and techniques. The GOP Structure Problem Here's a scenario every broadcast engineer has encountered: legacy set-top boxes or older TV models suddenly can't play your stream. The audio works, video starts and stops, or you see freezing. The culprit? Often, it's the GOP (Group of Pictures) structure. H.264 has been around since 2003—over 20 years. Almost everything supports it, yet you'll still find legacy equipment that struggles with certain configurations. Specifically, the number of B-frames can make or break compatibility. Why B-frames matter: They enable lower bitrates while maintaining quality by increasing encoding complexity through bidirectional prediction. But this comes at a cost—a more complex refere

How to Monitor Website Changes Automatically I run a few websites and need to know immediately when something breaks. A CSS regression, a broken layout, a missing section. Manual checking doesn't scale, and text-based monitoring misses visual issues. The {{screenshot-diff}} on Apify takes two screenshots and produces a pixel-level comparison with an overlay showing exactly what changed. How It Works Take a baseline screenshot of the correct state. Then take a current screenshot of the live page. The actor compares pixel by pixel and returns a diff image with changed pixels highlighted, plus a percentage telling you how much changed. import requests , time API_TOKEN = " YOUR_APIFY_TOKEN " def capture_screenshot ( url ): resp = requests . post ( " https://api.apify.com/v2/acts/weeknds~website-screenshot-api/runs " , headers = { " Authorization " : f " Bearer { API_TOKEN } " }, json = { " url " : url , " fullPage " : True } ) run_id = resp . json ()[ " data " ][ " id " ] time . sleep ( 15 ) items = requests . get ( f " https://api.apify.com/v2/acts/weeknds~website-screenshot-api/runs/ { run_id } /dataset/items " , headers = { " Authorization " : f " Bearer { API_TOKEN } " } ). json () return items [ 0 ][ " screenshotUrl " ] def compare_screenshots ( baseline_url , current_url ): resp = requests . post ( " https://api.apify.com/v2/acts/weeknds~screenshot-comparison-tool/runs " , headers = { " Authorization " : f " Bearer { API_TOKEN } " }, json = { " baselineImageUrl " : baseline_url , " currentImageUrl " : current_url , " threshold " : 0.01 } ) run_id = resp . json ()[ " data " ][ " id " ] time . sleep ( 10 ) items = requests . get ( f " https://api.apify.com/v2/acts/weeknds~screenshot-comparison-tool/runs/ { run_id } /dataset/items " , headers = { " Authorization " : f " Bearer { API_TOKEN } " } ). json () return items [ 0 ] baseline = capture_screenshot ( " https://mysite.com " ) current = capture_screenshot ( " https://mysite.com " ) result = compare_screenshots ( b

Parts 1 and 2 of this series ( Microsoft Entra extensibility is a gift. It is also Control Plane. and Securing the code that decides who Entra trusts ) made two static decisions. Where the code lives: a dedicated Control Plane subscription, directly under the root management group or under a dedicated Control Plane management group, never in the platform identity subscription or an application landing zone. What credential it uses to call out: a managed identity by default, federated identity credentials when the call must leave Azure, certificates as a tolerated middle step, and static symmetric keys never. Both decisions are one-time. You make them, you walk away, you do not touch them for months. The third decision is not like that. It is continuous, and it is the one most teams quietly skip: how do you know the deployed code on that Function App is still the code your reviewers approved? How do you know the Logic App workflow definition has not been rewritten since last Tuesday? How do you know nobody added a federated identity credential to the managed identity at 3 a.m. on a Saturday? The answer is monitoring. Not "we have Log Analytics turned on." Monitoring with a specific operating contract attached. The posture inversion For most Azure workloads, the default operating posture is reasonable trust. Engineers deploy. Pipelines run. Configuration drifts a little. The team reviews changes weekly. Anomalies are caught eventually. For a Microsoft Entra extension, that posture is wrong. The default has to be inverted. Once an Entra extension lands in production, every change to it is suspicious by default. Not "needs review." Not "let's check first." Suspicious. The default state of an alert firing on a Function App that hosts a custom claims provider is "the SOC is investigating, prove this was approved." If you cannot prove the change was approved within the team's response SLA, the change is treated as an incident and rolled back. That posture is harsh on purpo

SaaS software vendor HubSpot has described how its semantic search platform grew from a proof of concept into an internal service that now manages more than 20 billion vectors across 38-plus teams. The company says the system now supports agents, RAG, and contact deduplication, and that the increase in agent usage has made retrieval quality and latency more important than before.

Disclaimer: I'm currently learning web security through OWASP and PortSwigger Web Security Academy. These are my beginner-friendly notes rewritten as a blog to help reinforce my understanding. If you're just starting out, I hope this makes the topic easier to understand. What you'll learn: In this article you'll learn: ✔ What Broken Access Control is ✔ Vertical Privilege Escalation ✔ Security by Obscurity ✔ Parameter-Based Access Control ✔ Platform Misconfiguration ✔ Horizontal → Vertical Escalation ✔ IDOR ✔ Lessons learned from PortSwigger labs Concept Map: What is Broken Access Control? Broken Access Control happens when a user is able to access data, pages, or perform actions that they are not supposed to . Why should you care? Broken Access Control has ranked #1 in the OWASP Top 10 (2021) because it can expose sensitive data, allow privilege escalation, and let attackers perform actions they should never be able to perform. Think of a website with two types of users: Normal User Admin A normal user should only be able to view their own profile and perform basic actions. An admin, however, can manage users, delete accounts, change settings, etc. If a normal user somehow gains access to those admin features, that's Broken Access Control . In interview terms: Broken Access Control is the failure to properly enforce authorization, allowing users to perform actions beyond their intended permissions. 1. Vertical Privilege Escalation Vertical Privilege Escalation means moving up the permission hierarchy. Example: Normal User ↓ Admin A normal user should never be able to become an administrator. 1.1 Unprotected Functionality One of the simplest forms of Broken Access Control is Unprotected Functionality . Imagine a website has an admin page: /admin The developer removes the Admin button from the normal user's dashboard. Problem solved? No. If a user manually visits: /admin and the server doesn't verify whether they're actually an admin, the page opens. The mistake here

When you maintain a number of WordPress sites, showing the "last maintenance date" in the site list is the obvious move. A column of dates like 2026-05-21 . But in actual use, that alone falls short. A client put it well: "Besides the last maintenance date, it'd help to also show how many days have passed . And it'd be even better if the color changed at 15 / 30 / 60 days so I can see the risk level ." This post walks through that step — from "absolute date" to "relative elapsed days + color" — including the small design details. Why a date alone isn't enough An absolute date like 2026-05-21 is precise, but it pushes the "difference from today" calculation onto the user's head . Fine for five sites; as the managed set grows, reading "which ones are getting neglected" off a column of dates gets hard. The point of a maintenance inventory is to grasp which sites need attention at a glance. If so, what you should surface is less the absolute date and more the relative quantity — " how many days since the last maintenance " — and ideally let color convey "how many days until it's risky." The client's request landed exactly on this "absolute → relative + risk" shift. Four-tier color coding We went with four tiers by elapsed days. A small badge like (15 days ago) sits right after the last-maintenance date, and the color changes by threshold. Elapsed tier color meaning 0–14 days fresh green recently maintained, fine 15–29 days normal gray standard 30–59 days warn amber needs attention 60+ days danger red needs action green → gray → amber → red — just scrolling the list, "lots of red here" or "a cluster of sites I haven't touched lately" jumps out visually. The badge also gets a hover tooltip ("N days since last maintenance") to back up the number's meaning. Consolidate into helper functions The display logic is called from multiple places (list view, grid view), so scattering inline day calculations would be a DRY violation. We consolidated into a set of helpers. // Returns

Multi stage builds sao uma das melhores features do Docker para manter imagens pequenas e organizadas. Vou mostrar como aplicar isso em um projeto Python real. Crie um arquivo app.py simples: # app.py def main(): print("Hello from a multi stage build") if __name__ == "__main__": main() Agora crie o Dockerfile sem multi stage: FROM python:3.12-slim WORKDIR /app COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY . . CMD ["python", "app.py"] Essa imagem inclui o pip, o cache do pip e ferramentas de build que nao precisamos em producao. O resultado e uma imagem maior que o necessario. Com multi stage builds separamos o ambiente de build do ambiente final. Veja o mesmo Dockerfile com dois stages: FROM python:3.12-slim AS builder WORKDIR /app COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt FROM python:3.12-slim WORKDIR /app COPY --from=builder /usr/local/lib/python3.12/site-packages /usr/local/lib/python3.12/site-packages COPY . . CMD ["python", "app.py"] O primeiro stage instala as dependencias. O segundo stage copia so o que importa. O resultado e uma imagem final muito menor. Para construir e ver o tamanho: docker build -t minha-app . docker images | grep minha-app Para linguagens compiladas como Go o ganho e ainda maior. Veja um exemplo com uma aplicacao Go: FROM golang:1.23 AS builder WORKDIR /app COPY go.mod go.sum ./ RUN go mod download COPY . . RUN CGO_ENABLED=0 GOOS=linux go build -o /app/server FROM scratch COPY --from=builder /app/server /server CMD ["/server"] A imagem final comeca do zero (scratch). Nao tem shell, sistema operacional, nem ferramentas de build. So o binario compilado. Uma dica pratica: sempre nomeie seus stages com AS para facilitar a leitura. Use nomes como builder, test, ou dev. Isso ajuda a saber o que cada stage faz sem precisar contar linhas. That's all for now. Thanks for reading!

Originally published at ffmpeg-micro.com You need server-side video processing in your Swift app. Maybe you're building a Vapor backend that transcodes user uploads, a macOS utility that batch-converts media files, or a command-line tool that generates thumbnails. FFmpeg is the standard tool for the job, but getting it into a Swift project isn't as simple as adding a package dependency. Running FFmpeg from Swift with Process Swift's Foundation framework provides the Process class for running external commands. If FFmpeg is installed on the machine, you can shell out to it directly: import Foundation let process = Process () process . executableURL = URL ( fileURLWithPath : "/opt/homebrew/bin/ffmpeg" ) process . arguments = [ "-i" , "input.mp4" , "-c:v" , "libx264" , "-crf" , "23" , "-preset" , "medium" , "-c:a" , "aac" , "-b:a" , "128k" , "output.mp4" ] let pipe = Pipe () process . standardOutput = pipe process . standardError = pipe try process . run () process . waitUntilExit () let data = pipe . fileHandleForReading . readDataToEndOfFile () let output = String ( data : data , encoding : . utf8 ) ?? "" print ( output ) guard process . terminationStatus == 0 else { fatalError ( "FFmpeg failed with exit code \( process . terminationStatus ) " ) } This works on macOS and Linux. Install FFmpeg with brew install ffmpeg on macOS or apt-get install ffmpeg on Ubuntu, point executableURL at the binary, and you're running. But you own that FFmpeg install on every machine. On Linux servers, you're managing the binary across deploys. On macOS CI runners, you're adding Homebrew steps to your build pipeline. And on iOS, Process doesn't exist at all. Processing Video via Cloud API (No FFmpeg Install) Skip the local binary entirely. FFmpeg Micro exposes full FFmpeg capabilities through a REST API. Send a video URL, pick your settings, get processed video back. If you're familiar with how this works in Node.js or Kotlin , the pattern is identical. Here's the basic flow using URLSe

We just open-sourced Synapse , a governed control plane for software composition analysis, recon, evidence, and reporting. It is built for people who have to scan a dependency tree, prove what they found, and hand over a report that holds up. Site: https://synapse.kkloudtarus.net/ Code: https://github.com/KKloudTarus/synapse-ce (Apache-2.0) Why we built it The usual workflow is fragmented. One tool for the SBOM, another for vulnerabilities, a spreadsheet for licenses, a folder of screenshots for evidence, and a report you assemble by hand. Nothing is reproducible, and when a client asks "how do you know this is real," the answer lives in someone's memory. Adding an LLM that writes your findings only makes that worse. We wanted the opposite: fast, but provable. What it is Synapse runs the assessment lifecycle behind one control plane, in Go, clean architecture. A few ideas hold it together: Deterministic-first. Scanning, matching, license classification, and reporting are pure, reproducible Go. There is no model in the report path. Scope-gated execution. Every engagement carries a scope and an authorization window, enforced server-side before any tool runs. Tools run via argument arrays, never a shell string. Tamper-evident evidence. Every artifact is hash-chained and append-only. A broken chain blocks the report. Bounded automation. The optional AI layer only ever proposes. A distinct verifier or a human confirms. The agent can never confirm its own claim. What it does today: SBOM across 15+ ecosystems, multi-source vulnerability detection with risk-based prioritization (KEV, then EPSS, then CVSS), license compliance, reachability, and deterministic reports in CycloneDX, SPDX, SARIF, and OpenVEX. Try it git clone https://github.com/KKloudTarus/synapse-ce.git cd synapse-ce docker compose -f deploy/docker-compose.full.yml up --build # open http://localhost:5173 Or gate CI on real risk: ./bin/synapse-cli scan . --fail-on high .

Every beginner developer hits the same issue at some point. You learn a few basics, finish a tutorial, and then you have no idea what to build next. That gap can feel bigger than learning the code itself, because now the question is not “How do I write this?” but “What should I build at all?” This article is for that moment. I want to make it simple, practical, and useful, because project ideas do not need to be too advanced to be valuable. A good project is one that teaches you something, keeps you going, and gives you enough confidence to build the next one. Why project ideas are important There’s a common thing that I have noticed in most of the beginners, that is, watching too many tutorials. Tutorials are helpful, but actual learning starts when you try to build something on your own. That is when you start facing real decisions, small bugs, unclear logic, and the feeling of connecting different parts into one working product. That is one of the reasons why project ideas matter so much. The right idea gives you direction, but it also gives you energy. When the project feels too huge, you get stuck. When it feels too small or boring, you stop caring. The sweet spot is a project that feels possible and still a little exciting. This matters even more today. Tools like ChatGPT or Copilot can help you write code faster, but that doesn't solve the real problem beginners have. Writing the code was never the hard part for long but knowing what to build is. Start with problems you already know The easiest project ideas often come from your own life. Think about small things you do every day that feel annoying, repetitive, or messy. A simple to-do list, habit tracker, note saver, expense log, study planner, or meal planner can all become strong beginner projects if you build them well. This works because the problem is already familiar to you. You do not have to invent a fake use case or force a complicated feature list. You already know what the app should do, what feel

In this blog post, we will see how to performance test a RAG (Retrieval-Augmented Generation) application properly, covering both speed and correctness, and how to wire both into a CI/CD pipeline so regressions get caught before they reach production. Performance testing a RAG application requires two separate testing gates: one for speed and one for answer quality. Traditional load testing tools measure response times but cannot detect hallucinations, where a model returns fast but factually incorrect answers grounded in fabricated context rather than retrieved documents. The guide demonstrates using k6 for load testing end-to-end latency and DeepEval for evaluating faithfulness and answer relevancy using an LLM-as-judge approach. Both gates are integrated into a GitHub Actions CI/CD pipeline so regressions in either performance or output quality are caught automatically on every pull request before reaching production. If you've come from a JMeter or k6 background like I have, your first instinct with a RAG endpoint is probably to point a load test at it and check response times. That gets you halfway there. A RAG app can return a fast, confident, completely wrong answer, and a plain load test will never tell you that. You need two testing surfaces, not one: performance and quality. This guide covers both, using a single running example throughout: a documentation assistant that answers "How do I run JMeter in non-GUI mode?" against a small knowledge base. Why RAG breaks traditional load testing assumptions A conventional API returns a complete response and you measure the round trip. A RAG endpoint does two expensive things before it answers: it retrieves context from a vector store or search index, then it streams a generated response token by token. That second part matters a lot. A single request can stream hundreds of tokens over several seconds, so "request duration" as a single number hides two very different problems: how long the model took to start answe

Building an AI agent sounds complicated. It's not. By the end of this guide, you'll have a working agent that can search the web, remember conversations, and handle multi-step tasks. No frameworks, just TypeScript and an LLM API. What We're Building A research assistant agent that: Takes questions from users Uses tools (web search) when needed Remembers conversation history Handles errors without crashing Runs in about 150 lines of TypeScript This won't be production-ready, but it'll work and you'll understand every line. Prerequisites You need: Node.js 18 or higher Basic TypeScript knowledge An Anthropic API key ( get one free ) That's it. No prior AI experience needed. Setup (5 minutes) # Create project mkdir research-agent cd research-agent npm init -y # Install dependencies npm install @anthropic-ai/sdk dotenv # Install dev dependencies npm install -D typescript @types/node tsx # Initialize TypeScript npx tsc --init Create .env : ANTHROPIC_API_KEY = your-key-here Step 1: Define Your Types Create src/types.ts : export interface Message { role : ' user ' | ' assistant ' ; content : string ; } export interface Tool { name : string ; description : string ; input_schema : { type : ' object ' ; properties : Record < string , any > ; required ?: string []; }; execute : ( input : any ) => Promise < string > ; } Why these types matter: Strong typing prevents bugs. If you change how a tool works, TypeScript tells you everywhere that breaks. Step 2: Create a Simple Tool Create src/tools/search.ts : import { Tool } from ' ../types ' ; export const searchTool : Tool = { name : ' search_web ' , description : ' Search the internet for current information. Use this when you need facts, recent events, or data you do not know. ' , input_schema : { type : ' object ' , properties : { query : { type : ' string ' , description : ' The search query ' , }, }, required : [ ' query ' ], }, execute : async ( input : { query : string }) => { console . log ( `[Tool] Searching for: ${ input
