Stop Hand-Editing Fragile APT Lines: Practical deb822 `.sources` Files for Debian and Ubuntu

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

a fake bug fix PR hid a credential stealer in astro.config.mjs that used blockchain to receive commands

a malicious pull request was submitted in a 57k star github repo Egonex-AI/Understand-Anything and the pr description was also convincing, the test plan was fake and the real payload is hidden behind hundreds of whitespace characters on the last diff line. astro.config.mjs runs as a live nodejs module on every dev or preview. there is no sandbox which basically means it will affect more than a postinstall script. The second stage actually pulled commands from a tron blockchain address which is a public RPC nodes only so IP blocking does nothing. submitted by /u/BattleRemote3157 [link] [留言]

How to Build a LinkedIn Outreach Pipeline (Without Getting Your Account Banned)

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

How to use build-your-own-x: Master programming by recreating your favorite technologies from scratch.

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

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

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

Migrating From Transactional Email to Agent Accounts

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.)

How I Gave My AI Agent Persistent Memory Without Modifying Its Code

If you've ever worked with AI agents in production, you know the frustration: every new session starts from scratch. The agent has no memory of previous conversations, no context about ongoing projects, and you have to repeat yourself constantly. It's like Groundhog Day for your AI. I ran into this with a code assistant I was using for a multi-week refactoring project. It was great for one-off questions, but it couldn't remember what we discussed yesterday. I'd ask it about the architecture decisions we made last week, and it would stare at me blankly. I needed something that could carry context across sessions without forcing me to patch the agent's internals. I looked at the usual suspects: vector databases for RAG, ad-hoc session dumping, even fine-tuning. Each had a cost. RAG setups are powerful but often require custom tooling and tight integration. Session logs without structure are just noise. Fine-tuning is expensive and slow to iterate on. What I wanted was a self-contained system that worked with any agent, required no code changes to the agent, and actually understood what to keep and what to forget. That's when I found Memory Sidecar. It's an open-source project designed to run alongside any AI agent—Hermes, Claude Code, Cursor, Codex, or your own custom setup—as a separate process. It watches your agent's output, archives important conversations, builds a long-term knowledge base, and injects relevant context back before each new session. No patches, no invasive changes. How it works The architecture is simple on the surface but layered underneath. Agents write sessions to state.db and session files. The sidecar reads these, processes new content, and feeds through a three-tier retrieval system: Hot layer : Recent context with a small footprint (5 KB cap). This is the stuff the agent just talked about. Warm layer : Hindsight PostgreSQL database that stores summarised sessions and recent history. Cold layer : A knowledge graph (gbrain) combined with FTS5
