If you still manage APT repositories as long one-line deb ... entries, you are working with a format APT now explicitly marks as deprecated. It still works, but it is harder to read, harder to automate safely, and easier to get wrong when you add options like arch= or signed-by= . The better option is deb822 style .sources files. This post shows how to: read the structure of a .sources file migrate a legacy .list entry safely use Signed-By without falling back to apt-key disable a repository cleanly without deleting it verify that APT accepts the new configuration I am focusing on practical host administration, not packaging theory. Why move to deb822 now? The sources.list(5) man page now says the traditional one-line .list format is deprecated and may eventually be removed, though not before 2029. More importantly, deb822 solves real operational annoyances: fields are explicit instead of positional one stanza can describe multiple suites or types Enabled: no is cleaner than commenting lines in and out machine parsing is much easier Signed-By is clearer and safer in structured form On a current Debian host, you may already be using it without noticing: find /etc/apt/sources.list.d -maxdepth 1 -type f -name '*.sources' On my test system, the default Debian repository is already stored as /etc/apt/sources.list.d/debian.sources . The old format vs the new format A traditional one-line entry looks like this: deb [arch=amd64 signed-by=/etc/apt/keyrings/example.gpg] https://packages.example.com/apt stable main The same source in deb822 format becomes: Types: deb URIs: https://packages.example.com/apt Suites: stable Components: main Architectures: amd64 Signed-By: /etc/apt/keyrings/example.gpg That is the core win. Instead of cramming everything into one line and hoping spacing stays correct, each field says exactly what it means. Example 1, a clean Debian .sources file Here is a practical example for Debian using separate stanzas for the main archive and the security arch

TL;DR: A LinkedIn outreach pipeline is a background worker that signs in with your own session, opens profiles, sends connection requests and messages on a schedule you control, and can post content straight to your feed. The hard was staying invisible to LinkedIn's detection. We got to our nineteenth build in about two weeks. Along the way, the session kept dying after three profiles (a device fingerprint mismatch), the stealth layer turned out to be detectable on its own, an authenticated proxy refused to connect, and Chrome froze in ways no timeout caught. This is every failure and the fix that finally held. We built a LinkedIn marketing pipeline inside Ozigi because our own go-to-market runs on it. I didn't just want it to be another tool; I needed it to send real messages to real people without getting my personal account flagged. The very first version we built worked for sourcing and reaching three leads, then the session died. The second version got past that and froze instead. This pattern repeated for two weeks and led us from building v1 of our LinkedIn worker to the current version 26. This article is like a cleaned-up version of our build log for educational purposes. If you are trying to reach people on LinkedIn from code, you will hit most of these walls in roughly this order. I will name the exact failure each time, because "it stopped working" helped me precisely never. What Does a LinkedIn Outreach Pipeline Actually Do? A complete LinkedIn outreach pipeline does four jobs: It signs in with your session cookie so LinkedIn sees you, not a script. It opens a lead's profile. It sends a connection request or a message, depending on whether you are already a first-degree connection. And it can publish a post to your feed. The first three are outreach. The fourth is content. They share the same infrastructure, which matters later. None of these look overly complicated logic. You click a button, type into a box, press send. But the reason this turned into

This is a submission for the June Solstice Game Jam Your Iphone can now celebrate the Solstace! When you have a hammer- everything is a nail! This installment brings a Flutter build running on IOS! A complete IOS App is built using Flutter with Xcode and some Joystick bugs are fixed! What I Built When it comes to Summar Solstace — the place to be is Sweden. It is one of the highlights of the calendar. This project aimed to recreate some of the mystique around the event- just in time for some fresh surestromming! Now you can get it on the GO! In a previous article, the web app was refactored to be Flutter compatible. This installment adds an IOS build from the Flutter code base and deploys it to an Iphone. Code GitHub repo is here: GitHub - xbill9/midsommer-flutter: Midsommer Madness game in Flutter / Web view Midsommer Madness game in Flutter / Web view The first version of the article built the app out as a web based game: Midsommer Madness Then, the app was converted to Android: Android Midsommer Madness And finally to Flutter: Flutter Midsommer Madnesss Game Play The key levels include: IKEA Warehouse: Battle crowded, flatpack-carrying shoppers who throw box projectiles at you. Systembolaget: The state-owned liquor shop crowded with drunk Swedes stumbling and lobbing green beer bottles. Lördagsgodis: Sugar rush Saturday! Dodge hyperactive, strung-out Swedish kids throwing sweet candy projectiles. The Swedish Pub: Sing along with Frank Zappa fans singing “Bobby Brown” (shouting and firing glowing letters B, O, B, B, Y). Volvo Highway: A survival lane-crossing level where… My Lingonberries are ripening- get to work! How do you deploy this? To build for IOS- you need a recent Mac system with Xcode tools installed along with Flutter. You can use standard Mac installs for Xcode and Flutter is available directly or via Homebrew. The build environment will look similar to this: The Makefile included with the project has IOS targets: m3:midsommer-flutter xbill$ make help

Are you tired of just using frameworks and libraries without truly understanding how they work under the hood? Imagine gaining an unparalleled depth of knowledge and problem-solving skills by building your favorite technologies from scratch. Master Programming by Recreating Your Favorite Technologies From Scratch As developers, we spend a significant portion of our time using tools, frameworks, and libraries built by others. While incredibly efficient, this often creates a knowledge gap. We know how to use a tool, but not why it works the way it does, or what fundamental problems it solves. This is where the "build-your-own-X" (BYOX) philosophy comes in. It's a powerful learning strategy where you recreate simplified versions of existing technologies – be it a web server, a database, a version control system, or even a frontend framework – using only fundamental programming concepts. It's not about replacing established tools; it's about dissecting them, understanding their core principles, and in doing so, mastering the craft of programming itself. Why Bother? The Profound Benefits of Building Your Own Investing time in building your own versions of existing technologies offers a wealth of benefits that accelerate your growth as a developer: Deepened Understanding: No more black boxes

I Cut My Next.js + Supabase App Load Time by 73% - Here Are the 5 Techniques That Actually Worked Last month, our SaaS dashboard was embarrassingly slow . 4.2 seconds to load the main page. Users were complaining. Conversion rates were tanking. Today? 1.1 seconds . 73% faster. Here's exactly what worked (and what didn't). The Problem: Death by a Thousand Database Calls Our dashboard showed user projects, team members, recent activity, and notifications. Sounds simple, right? Wrong. Each component was making its own database calls. The projects list fetched projects, then made separate calls for each project's stats. The activity feed loaded events, then fetched user details for each event. Classic N+1 query problem, but worse. Technique #1: Strategic Data Fetching Consolidation Before: 47 database calls to load the dashboard After: 3 database calls The fix wasn't fancy. We consolidated related data into single queries using Supabase's nested select syntax: // ❌ Before: Multiple separate calls const projects = await supabase . from ( ' projects ' ). select ( ' * ' ) const stats = await Promise . all ( projects . map ( p => supabase . from ( ' project_stats ' ). select ( ' * ' ). eq ( ' project_id ' , p . id )) ) // ✅ After: Single consolidated call const projects = await supabase . from ( ' projects ' ) . select ( ` *, project_stats(*), team_members(count), recent_activity:activities(*, user:users(name, avatar_url)) ` ) . limit ( 10 ) Result: Dashboard load time dropped from 4.2s to 2.8s (33% improvement) Technique #2: Aggressive Caching with Smart Invalidation Most dashboard data doesn't change every second. We implemented a three-tier caching strategy: // Static data: Cache indefinitely const categories = await supabase . from ( ' categories ' ) . select ( ' * ' ) . cache ({ revalidate : false }) // Semi-static data: Cache with revalidation const userProjects = await supabase . from ( ' projects ' ) . select ( ' * ' ) . eq ( ' user_id ' , userId ) . cache ({ revali

Next.js + Supabase Performance Optimization: From Slow to Lightning Fast Last month, I optimized a Next.js + Supabase application that was frustratingly slow. Initial page load took 4.2 seconds, Lighthouse performance score was 62, and users were complaining. After applying these optimization techniques, we achieved: 70% faster load times (4.2s → 1.3s) Lighthouse score of 96 (up from 62) LCP improved by 65% (3.8s → 1.3s) 50% reduction in database queries Here's exactly how we did it. The Starting Point: Measuring Performance Before optimizing anything, we measured current performance using: Lighthouse (Chrome DevTools): Performance: 62 First Contentful Paint (FCP): 2.1s Largest Contentful Paint (LCP): 3.8s Total Blocking Time (TBT): 420ms Cumulative Layout Shift (CLS): 0.18 Real User Monitoring: Average page load: 4.2s Time to Interactive: 5.1s Database query time: 850ms average The Problems: Unoptimized database queries No caching strategy Large JavaScript bundles Unoptimized images Blocking render paths Too many client-side fetches Let's fix each one. 1. Database Query Optimization Problem: N+1 Queries The biggest performance killer was N+1 queries. We were fetching posts, then fetching the author for each post individually. // ❌ Bad: N+1 queries (1 + N database calls) async function getPosts () { const { data : posts } = await supabase . from ( ' posts ' ) . select ( ' id, title, author_id ' ) // Fetching author for each post = N queries const postsWithAuthors = await Promise . all ( posts . map ( async ( post ) => { const { data : author } = await supabase . from ( ' users ' ) . select ( ' name, avatar ' ) . eq ( ' id ' , post . author_id ) . single () return { ... post , author } }) ) return postsWithAuthors } Impact: 50 posts = 51 database queries (850ms total) Solution: Use Joins // ✅ Good: Single query with join (1 database call) async function getPosts () { const { data : posts } = await supabase . from ( ' posts ' ) . select ( ` id, title, author:users(nam

This is what most agent email code looks like today: // SendGrid / Resend / Postmark — outbound only await sendgrid . send ({ to : " prospect@example.com " , from : " outreach@yourcompany.com " , subject : " Following up on your demo request " , html : " <p>Hi Alice — wanted to follow up on...</p> " , }); // That's it. If Alice replies, the agent never sees it. The send works fine. The problem is everything after: when Alice replies, that reply bounces, lands at a no-reply nobody reads, or hits a human inbox the agent can't reach programmatically. The agent is talking into a void. Transactional providers were built for receipts and password resets — one-way mail — and an agent that's supposed to hold a conversation needs a receive path those APIs simply don't have. Agent Accounts (a beta feature from Nylas) close that gap with a full hosted mailbox: send and receive, with threading, webhooks, and folders built in. Here's what the migration actually involves. The delta, honestly Outbound barely changes — it's still an API call. The new parts are everything transactional providers never gave you: Concern Transactional provider Agent Account Outbound API call Same — POST /messages/send Inbound None (or polling a shared inbox) Replies land automatically, fire message.created Threading You track Message-ID yourself Headers preserved, threads grouped automatically Reply detection Parse forwards, poll Webhook within seconds of arrival DNS SPF/DKIM/DMARC for the provider MX, SPF, DKIM, DMARC for the mailbox host Provision the mailbox One call creates the account; the response includes a grant_id that identifies it on every later request: curl --request POST \ --url "https://api.us.nylas.com/v3/connect/custom" \ --header "Authorization: Bearer $NYLAS_API_KEY " \ --header "Content-Type: application/json" \ --data '{ "provider": "nylas", "settings": { "email": "outreach@agents.yourcompany.com" } }' (Or nylas agent account create outreach@agents.yourcompany.com from the CLI.)

A few days ago, I shared an article: You Don't Need Another Agent. You Need a Linter. Then I did what I do with anything I write: shared it around — a few publications, a few channels. Two reasons: First, feedback. I'd genuinely rather get roasted and fix my blind spots than stay comfortable and wrong. Second, let's be honest: reach. Every writer enjoys seeing a few more views. Most of the responses were positive. One wasn't. A publication rejected it with the reason: LOW_QUALITY Fair enough. It means there's room for improvement. Funny enough, my caffeinated 1 AM brain disagreed. Then it did what every developer does when someone says "this isn't good enough." It took that personally. So I went back and reread the article. And after the initial ego check, I realized something serious: The article talked in detail about ESLint, why it matters more in an AI-assisted world than ever. What it did not do was answer the question that actually matters: What is ESLint, how does it work, and why has half the JavaScript ecosystem quietly built its quality process around it? So let's fix that. Now, this isn't a sequel to my last piece about untangling vibe-coded code. It stands on its own — one thing, done properly . A complete teardown of ESLint: What it is How it works internally Why companies use it as a quality gate The different classes of problems it solves How plugins work How to write your own rules Where it fails Why it still beats many AI-based review systems Fair warning. This article is going to be technical. There will be syntax trees. There will be compiler concepts. There will be enough JavaScript internals to make frontend developers slightly uncomfortable. I'll try my best to keep it readable not letting it turn into another manual - which nobody finishes. Let's start with the question most people never ask. What Is ESLint Actually Doing? Most developers describe ESLint like this: It checks code for mistakes. Technically true. Also completely useless. That's
