The Steam Machine fits my TV, my desk, and my life

For the last couple weeks, I've been in an extremely lucky position: I've been spending a lot of time playing games on Valve's Steam Machine. We gave the Steam Machine a 6, and I don't disagree with my colleague Sean Hollister's review. But even though I already own a PS5 and an Xbox Series X, […]

The robotaxi law that could ban Tesla

For more than a decade, one question has loomed over the race to build autonomous vehicles: Are cameras alone enough to safely replace human drivers, or do truly driverless cars need additional, overlapping sensors like lidar and radar to navigate the world reliably? Tesla has bet billions of dollars that artificial intelligence and cameras are […]

Why I Stopped Writing tap() Inside rxResource Streams

There's a pattern I see a lot in Angular codebases that adopted Signals early: a developer discovers rxResource , loves that it handles loading and error state automatically, and then immediately reaches for tap() to write a signal inside the stream. private readonly resource = rxResource ({ params : () => this . paramsSignal (), stream : ({ params }) => this . api . fetch ( params ). pipe ( tap ( data => this . sideSignal . set ( data . meta )) // 💥 ) }); This looks harmless. It runs in development without complaint in zone-based Angular. Then you enable zoneless — or Angular tightens its reactive graph enforcement — and you get NG0600: Writing to signals is not allowed in a reactive context . The rxResource stream runs inside Angular's reactive scheduler. Signal writes there aren't just discouraged — they're illegal by design. The scheduler assumes computed signals and reactive contexts are read-only during evaluation. A write mid-computation breaks the glitch-free guarantee Angular's signal graph is built on. The fix I landed on: make the stream return everything it needs to return, as a single typed value. interface ResourceValue { readonly sections : Section []; readonly meta : Meta ; } private readonly resource = rxResource < ResourceValue , Params > ({ stream : ({ params }) => this . api . fetch ( params ). pipe ( map ( data => ({ sections : transform ( data ), meta : data . meta })) ) }); No tap . No side signal. Everything the rest of the store needs lives in resource.value() and can be read via computed . The lesson isn't "don't use tap". The lesson is that rxResource has a contract: it is a read primitive . Its stream is for fetching and transforming. If you're writing signals inside it, you're treating it as a command bus — and that's a different tool. Originally published on ysndmr.com .

دليل عملي لاختبار التحميل لواجهات API باستخدام أرتيلري

Artillery هي مجموعة أدوات مفتوحة المصدر لاختبار التحميل مبنية على Node.js. تتيح لك توليد حركة مرور عالية التزامن على واجهة برمجة التطبيقات (API) من خلال ملف YAML بسيط: تحدد مراحل التحميل، تصف تدفقات الطلبات، تشغل artillery run script.yml ، ثم تقرأ نسب زمن الاستجابة المئوية، معدلات الطلبات، وعدد الأخطاء. يشرح هذا الدليل طريقة تثبيت Artillery v2، كتابة اختبار عملي، تشغيله، استخراج النتائج بالطريقة الصحيحة في v2، وربطه بمسار CI. جرّب Apidog اليوم ما هو Artillery ومتى تستخدمه؟ ينشئ Artillery مستخدمين افتراضيين (VUs) يرسلون طلبات إلى نقاط النهاية لديك ويقيسون قدرة النظام على تحمل الحمل المستمر. المستخدم الافتراضي هو عميل مُحاكى ينفذ سيناريو خطوة بخطوة، كما يفعل مستخدم أو خدمة حقيقية. استخدم Artillery عندما تريد إجابات عملية على أسئلة الأداء مثل: كيف يتغير زمن الاستجابة p95 عند 50 طلبًا في الثانية؟ عند أي معدل وصول تبدأ الأخطاء بالظهور؟ هل تبقى واجهة API مستقرة لمدة 5 دقائق من الحمل المستمر؟ هل يتدهور الأداء تدريجيًا مع استمرار الضغط؟ الميزة الأساسية في Artillery أن الاختبار تصريحي. بدل كتابة حلقات تزامن يدويًا، تصف شكل الحمل في YAML. وبما أنه يعمل فوق Node.js، يمكنك تشغيل نفس الاختبار محليًا وفي CI. إذا كنت تقارن الأدوات، راجع ملخص أفضل أدوات اختبار التحميل و مقارنة برامج اختبار التحميل لفهم الفروقات بين k6 وJMeter وGatling وغيرها. تثبيت Artillery v2 اسم الحزمة هو artillery ، والإصدار الرئيسي الحالي هو v2. ثبته عالميًا عبر npm: npm install -g artillery@latest artillery version تحتاج إلى إصدار LTS حديث من Node.js. يعمل Artillery على Windows وmacOS وLinux. إذا كنت لا تريد تثبيت الحزمة عالميًا، استخدم npx : npx artillery@latest run script.yml كتابة اختبار Artillery يتكون ملف الاختبار من قسمين أساسيين: config : يحدد الهدف ومراحل الحمل والمتغيرات. scenarios : يحدد ما يفعله كل مستخدم افتراضي. مثال كامل: config : target : " https://api.example.com" phases : - name : " Warm up" duration : 60 arrivalRate : 5 - name : " Ramp to peak" duration : 120 arrivalRate : 5 rampTo : 50 - name : " Sustained load" duration : 300 arrivalRate : 50 maxVusers : 500 variables : productId : - " 100

How I add semantic search to a Next.js site using Sanity Embeddings

Sanity Embeddings semantic search in Next.js is one of those features that looks complicated from the outside but is surprisingly lean to wire up once you understand the moving parts. This post covers the current native Embeddings feature built into Sanity datasets — not the older Embeddings Index API, which Sanity is sunsetting. If you found a guide that talks about a separate embeddings-index resource you have to provision via the Management API, it is stale; skip it. What Sanity Embeddings actually is Sanity's native Embeddings feature lets you mark document types for vector indexing directly inside your dataset. Sanity handles the embedding model and the vector store; you never manage a separate service. Queries use a dedicated sanity.embeddings.query GROQ function that takes a natural-language string and returns documents ranked by semantic similarity. The feature is available on Growth and Enterprise plans as of mid-2026. The workflow has three parts: Configure which document types get indexed (dataset setting or the Embeddings pane in Sanity Studio). Run a semantic query from your Next.js route handler using the Sanity client. Render the results in a search UI component. Setting up the embeddings index in your dataset Go to Manage → your project → Embeddings (or open the Embeddings pane inside Sanity Studio if your plan surfaces it there). Create an index, give it a name (e.g. site_search ), and select which document types and fields to embed. For a blog you would typically pick post with fields title , excerpt , and body (plain text extracted from Portable Text). Sanity backfills existing documents automatically. New and updated documents are re-embedded on publish via an internal webhook — you do not configure that yourself. There is no code required for the indexing step. The index name you choose here ( site_search ) is what you will pass in the GROQ query. Querying embeddings from a Next.js route handler Create a route handler that accepts a search term,

You Can't Secure What You Can't See: Shadow AI and the Inventory Problem

Part 1 of "Trust the Machine" -> a series on building AI infrastructure that is secure, compliant, and governable by design. Most organizations can produce an accurate catalog of the web services they operate. Far fewer can produce an equivalent catalog of the AI systems they run — the models, fine-tunes, retrieval pipelines, agents, and third-party AI APIs now embedded throughout their products and internal tooling. This asymmetry defines the state of AI security in 2026. Adoption has outpaced oversight. Industry reporting this year has described a surge in enterprise AI activity on the order of 83% year over year, with governance and visibility lagging well behind. The consequence is a large and only partially mapped attack surface — one that many organizations cannot fully enumerate, let alone defend. Every mature security program rests on a single first principle: you cannot protect what you cannot see. Artificial intelligence is no exception. Before threat-modeling an agent or authoring a guardrail, an organization must be able to answer a deceptively difficult question: what AI is running across the environment, and who is accountable for it? This post examines how to build that answer. The rise of shadow AI Shadow IT — the unsanctioned adoption of tools outside official channels has been a recognized challenge for decades. Shadow AI is its faster-moving successor, and it appears in more forms than most inventories are designed to detect: Embedded API calls. A product team integrates a hosted model in a few lines of code and an API key, with no formal review. Copilots and assistants enabled across existing SaaS platforms, frequently activated by the vendor rather than the customer. Fine-tunes and adapters trained on internal data and stored in locations that fall outside standard scanning. Agents and automations that have incrementally acquired the ability to act—filing tickets, sending communications, initiating transactions—one permission at a time. Model de

TanStack Start vs Nuxt: One Framework to rule them all?

I love Nuxt and I really like TanStack Start. But which one is better? Or are they about the same? And if they are about the same, does it do anything my Nuxt setup can't, and is that worth leaving Vue for React? So I decided to build the same app in both frameworks and take a look. Read on below to find out! If you'd rather watch a video, check out the video on the same topic! The app In both frameworks I built a small GitHub user lookup app. You type a username, the profile gets fetched on the server, and the username lands in the URL as a ?user= query param so the result is shareable. Type ErikCH , hit enter, and the card renders. Refresh the page and it's still there. It has the same behaviour so the difference lies in the code. Difference one: server functions vs server routes On the Nuxt side we call a server route from useAsyncData . Server are the more idiomatic way to use Nuxt to call things on the server. <!-- app/pages/index.vue --> < script setup lang= "ts" > import { z } from ' zod ' import type { GithubUser } from ' ~~/server/api/github.get ' definePageMeta ({ props : route => z . object ({ user : z . string (). default ( '' ) }). parse ( route . query ), }) const props = defineProps < { user : string } > () const router = useRouter () const input = ref ( props . user ) const { data , error } = await useAsyncData ( ' github-user ' , () => props . user ? $fetch < GithubUser > ( ' /api/github ' , { query : { user : props . user } }) : Promise . resolve ( null ), { watch : [() => props . user ] }, ) function lookup () { router . push ({ query : { user : input . value . trim () } }) } </ script > The props option on definePageMeta maps the query into a typed page prop and re-runs on client navigation. useAsyncData fetches when there's a username and refetches whenever it changes. The conditional that returns Promise.resolve(null) skips the request on an empty query param, (or when you first load). The server route does the outbound call: // server/api/gith

Deploying Matomo Analytics - An Open-Source Google Analytics Alternative

Matomo is an open-source web analytics platform that keeps full ownership of visitor data on infrastructure you control, a privacy-first alternative to Google Analytics. This guide deploys Matomo using Docker Compose with a MariaDB backend, Nginx as the entry point, and Certbot issuing the TLS certificate before the stack goes live. By the end, you'll have Matomo tracking a website with a signed HTTPS certificate at your domain. Prepare Docker $ sudo usermod -aG docker $USER $ newgrp docker Set Up the Project 1. Create the project directory: $ mkdir matomo && cd matomo 2. Open the firewall: $ sudo ufw allow 80/tcp $ sudo ufw allow 443/tcp 3. Create the environment file: $ nano .env MYSQL_ROOT_PASSWORD = your_strong_mysql_root_password MYSQL_PASSWORD = your_strong_mysql_matomo_password Use passwords of at least 16 characters. 4. Create the Nginx config: $ mkdir nginx $ nano nginx/matomo.conf server { listen 80 ; server_name matomo.example.com ; location /.well-known/acme-challenge/ { root /var/www/certbot ; } location / { return 301 https:// $host$request_uri ; } } server { listen 443 ssl http2 ; server_name matomo.example.com ; ssl_certificate /etc/letsencrypt/live/matomo.example.com/fullchain.pem ; ssl_certificate_key /etc/letsencrypt/live/matomo.example.com/privkey.pem ; location / { proxy_pass http://app:80 ; proxy_set_header Host $host ; proxy_set_header X-Real-IP $remote_addr ; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for ; proxy_set_header X-Forwarded-Proto $scheme ; } } Replace every matomo.example.com occurrence with your domain — it appears in both server blocks and the certificate paths. Deploy with Docker Compose $ nano docker-compose.yaml services : db : image : mariadb:11.4 command : --max-allowed-packet=64MB restart : always volumes : - matomo-db-data:/var/lib/mysql environment : - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} - MYSQL_DATABASE=matomo - MYSQL_USER=matomo - MYSQL_PASSWORD=${MYSQL_PASSWORD} networks : - matomo-net app : image
