Report Abuse joe-re Posted on Jan 12 I Built a Desktop App to Supercharge My TMUX + Claude Code Workflow # claudecode # tauri # productivity # tmux Background Until recently, I was primarily using Cursor for AI-assisted coding. The editor-centric AI integration worked really well with my development style—it made the feedback loop smooth when AI-generated code didn't match my intentions, whether I needed to manually fix it or provide additional instructions. But everything changed when Opus 4.5 was released in late November last year. Opus 4.5 delivers outputs that match my expectations far better than any previous model. Claude Code's CUI-first design also feels natural to my workflow. Now, Claude Code has become the center of my development process. I've locked in Opus 4.5 as my daily driver. I typically run multiple Claude Code sessions simultaneously—across different projects or multiple branches using git worktree. Managing notifications and checking outputs across these sessions is critical. I was using OS notifications to check in whenever changes happened, but I kept missing them. I wanted something better. So I built an app to streamline my workflow. What I Built eyes-on-claude-code It's a cross-platform desktop application built with Tauri . I've only tested it on macOS (my daily environment), but the codebase is designed to support Linux as well. My Environment & Workflow This app is primarily designed to optimize my own workflow, so the features reflect my environment and habits. I develop using Ghostty + tmux . My typical workflow looks like this: Draft ideas and design in Markdown Give instructions to Claude Code (using Plan mode for larger tasks) Review the diff of generated code, then provide additional instructions or continue Features Multi-Session Monitoring Dashboard The dashboard monitors Claude Code sessions by receiving events through hooks configured in the global settings.json . Since I keep this running during development, I designed it with a minimal, non-intrusive UI. Always-on-top mode (optional) ensures the window doesn't get buried under other apps—so you never miss a notification. Transparency settings let you configure opacity separately for active and inactive states. When inactive, you can make it nearly invisible so it doesn't get in the way. It's there in the top-right corner, barely visible. Status Display & Sound Notifications Sessions are displayed with one of four states: State Meaning Display Active Claude is working 🟢 WaitingPermission Waiting for permission approval 🔐 WaitingInput Waiting for user input (idle) ⏳ Completed Response complete ✅ Sound effects play on state changes (can be toggled off): Waiting (Permission/Input) : Alert tone (two low beeps) Completed : Completion chime (ascending two-note sound) I'm planning to add volume control and custom commands in the future—like using say to speak or playing music on completion 🎵 Git-Based Diff Viewer I usually review AI-generated changes using difit . I wanted to integrate that same flow into this app, so you can launch difit directly on changed files. Huge thanks to the difit team for building such a great tool! tmux Integration When developing, I use tmux panes and tabs to manage multiple windows. My typical setup is Claude Code on the left half, and server/commands on the right. When working across multiple projects or branches via git worktree, it's frustrating to hunt for which tmux tab has Claude Code running. So I added a tmux mirror view that lets you quickly check results and give simple instructions without switching tabs. How It Works The app uses Claude Code hooks to determine session status based on which hooks fire. Event Flow I didn't want to introduce complexity with an intermediate server for inter-process communication. So I went with a simple approach: hooks write to log files, and the app watches those files. Hooks write logs to a temporary directory ( .local/eocc/logs ), which the app monitors. Since Claude Code runs in a terminal, hooks can access terminal environment paths. This lets me grab tmux and npx paths from within hooks and pass them to the app. Mapping Hooks to Status Claude Code provides these hook events: https://code.claude.com/docs/hooks-guide Here's how I map them to session states: Event Usage Session State session_start (startup/resume) Start a session Active session_end End a session Remove session notification (permission_prompt) Waiting for approval WaitingPermission notification (idle_prompt) Waiting for input WaitingInput stop Response completed Completed post_tool_use After tool execution Active user_prompt_submit Prompt submitted Active Conclusion I've only been using Claude Code as my primary tool for about two months, and I expect my workflow will keep evolving. Thanks to AI, I can quickly build and adapt tools like this—which is exactly what makes this era so exciting. If your workflow is similar to mine, give it a try! I'd love to hear your feedback.

Report Abuse Mohammad-Idrees Posted on Jan 13 Applying First-Principles Questioning to a Real Company Interview Question # career # interview # systemdesign Case Study: Designing a Chat System (Meta / WhatsApp–Style) This section answers a common follow-up interview request: “Okay, now apply this thinking to a real problem.” We will do exactly that — without jumping to tools or architectures first . The goal is not to “design WhatsApp,” but to demonstrate how interviewers expect you to think . The Interview Question (Realistic & Common) “Design a chat system like WhatsApp.” This is a real company interview question asked (in variants) at: Meta Uber Amazon Stripe Most candidates fail this question not because it’s hard, but because they start in the wrong place . What Most Candidates Do (Wrong Start) Typical opening: “We’ll use WebSockets” “We’ll use Kafka” “We’ll shard by user ID” This skips reasoning. A strong candidate pauses and applies the checklist. Applying the First-Principles Checklist Live We will apply the same five questions , in order, and show what problems naturally surface. 1. State “Where does state live? When is it durable?” Ask This Out Loud in the Interview What information must the chat system remember for it to function correctly? Identify Required State (No Design Yet) Users Conversations Messages Message delivery status Now ask: Which of this state must never be lost? Answer: Messages (core product) Conversation membership First-Principles Conclusion Messages must be persisted In-memory-only solutions are insufficient What the Interviewer Sees You identified correctness-critical state before touching architecture. 2. Time “How long does each step take?” Now we introduce time. Break the Chat Flow User sends message Message is stored Message is delivered to recipient(s) Ask: Which of these must be fast? Sending a message → must feel instant Delivery → may be delayed (offline users) Critical Question Does the sender wait for delivery confirmation? If yes: Latency depends on recipient availability If no: Sending and delivery are time-decoupled First-Principles Conclusion Message acceptance must be fast Delivery can happen later This naturally introduces asynchrony , without naming any tools. 3. Failure “What breaks independently?” Now assume failures — explicitly. Ask What happens if the system crashes after accepting a message but before delivery? Possible states: Message stored Recipient not notified yet Now ask: Can delivery be retried safely? This surfaces a key invariant: A message must not be delivered zero times or multiple times incorrectly. Failure Scenarios Discovered Duplicate delivery Message loss Inconsistent delivery status First-Principles Conclusion Message delivery must be idempotent Storage and delivery failures must be decoupled The interviewer now sees you understand distributed failure , not just happy paths. 4. Order “What defines correct sequence?” Now introduce multiple messages . Ask Does message order matter in a conversation? Answer: Yes — chat messages must appear in order Now ask the dangerous question: Does arrival order equal delivery order? In distributed systems: No guarantee Messages can: Be processed by different servers Experience different delays First-Principles Conclusion Ordering is part of correctness It must be explicitly modeled (e.g., sequence per conversation) This is a senior-level insight , derived from questioning alone. 5. Scale “What grows fastest under load?” Now — and only now — do we talk about scale. Ask As usage grows, what increases fastest? Likely answers: Number of messages Concurrent active connections Offline message backlog Now ask: What happens during spikes (e.g., group chats, viral events)? You discover: Hot conversations Uneven load Memory pressure from live connections First-Principles Conclusion The system must scale on messages , not users Load is not uniform What We Have Discovered (Before Any Design) Without choosing any tools, we now know: Messages must be durable Sending and delivery must be decoupled Failures must not cause duplicates or loss Ordering is a correctness requirement Message volume, not user count, dominates scale This is exactly what interviewers want to hear before you propose architecture. What Comes Next (And Why It’s Easy Now) Only after this reasoning does it make sense to talk about: Persistent storage Async delivery Streaming connections Partitioning strategies At this point, architecture choices are obvious , not arbitrary. Why This Approach Scores High in Interviews Interviewers are evaluating: How you reason under ambiguity Whether you surface hidden constraints Whether you understand failure modes They are not testing whether you know WhatsApp’s internals. This method shows: Structured thinking Calm problem decomposition Senior-level judgment Common Candidate Mistakes (Seen in This Question) Jumping to WebSockets without discussing durability Ignoring offline users Assuming message order “just works” Treating retries as harmless Talking about scale before correctness Every one of these mistakes is prevented by the checklist. Final Reinforcement: The Checklist (Again) Use this verbatim in interviews: Where does state live? When is it durable? Which steps are fast vs slow? What can fail independently? What defines correct order? What grows fastest under load? Final Mental Model Strong candidates design systems. Exceptional candidates design reasoning .

Report Abuse Mohammad-Idrees Posted on Jan 13 Applying First-Principles Questioning to a Real Company Interview Question # career # interview # systemdesign Case Study: Designing a Chat System (Meta / WhatsApp–Style) This section answers a common follow-up interview request: “Okay, now apply this thinking to a real problem.” We will do exactly that — without jumping to tools or architectures first . The goal is not to “design WhatsApp,” but to demonstrate how interviewers expect you to think . The Interview Question (Realistic & Common) “Design a chat system like WhatsApp.” This is a real company interview question asked (in variants) at: Meta Uber Amazon Stripe Most candidates fail this question not because it’s hard, but because they start in the wrong place . What Most Candidates Do (Wrong Start) Typical opening: “We’ll use WebSockets” “We’ll use Kafka” “We’ll shard by user ID” This skips reasoning. A strong candidate pauses and applies the checklist. Applying the First-Principles Checklist Live We will apply the same five questions , in order, and show what problems naturally surface. 1. State “Where does state live? When is it durable?” Ask This Out Loud in the Interview What information must the chat system remember for it to function correctly? Identify Required State (No Design Yet) Users Conversations Messages Message delivery status Now ask: Which of this state must never be lost? Answer: Messages (core product) Conversation membership First-Principles Conclusion Messages must be persisted In-memory-only solutions are insufficient What the Interviewer Sees You identified correctness-critical state before touching architecture. 2. Time “How long does each step take?” Now we introduce time. Break the Chat Flow User sends message Message is stored Message is delivered to recipient(s) Ask: Which of these must be fast? Sending a message → must feel instant Delivery → may be delayed (offline users) Critical Question Does the sender wait for delivery confirmation? If yes: Latency depends on recipient availability If no: Sending and delivery are time-decoupled First-Principles Conclusion Message acceptance must be fast Delivery can happen later This naturally introduces asynchrony , without naming any tools. 3. Failure “What breaks independently?” Now assume failures — explicitly. Ask What happens if the system crashes after accepting a message but before delivery? Possible states: Message stored Recipient not notified yet Now ask: Can delivery be retried safely? This surfaces a key invariant: A message must not be delivered zero times or multiple times incorrectly. Failure Scenarios Discovered Duplicate delivery Message loss Inconsistent delivery status First-Principles Conclusion Message delivery must be idempotent Storage and delivery failures must be decoupled The interviewer now sees you understand distributed failure , not just happy paths. 4. Order “What defines correct sequence?” Now introduce multiple messages . Ask Does message order matter in a conversation? Answer: Yes — chat messages must appear in order Now ask the dangerous question: Does arrival order equal delivery order? In distributed systems: No guarantee Messages can: Be processed by different servers Experience different delays First-Principles Conclusion Ordering is part of correctness It must be explicitly modeled (e.g., sequence per conversation) This is a senior-level insight , derived from questioning alone. 5. Scale “What grows fastest under load?” Now — and only now — do we talk about scale. Ask As usage grows, what increases fastest? Likely answers: Number of messages Concurrent active connections Offline message backlog Now ask: What happens during spikes (e.g., group chats, viral events)? You discover: Hot conversations Uneven load Memory pressure from live connections First-Principles Conclusion The system must scale on messages , not users Load is not uniform What We Have Discovered (Before Any Design) Without choosing any tools, we now know: Messages must be durable Sending and delivery must be decoupled Failures must not cause duplicates or loss Ordering is a correctness requirement Message volume, not user count, dominates scale This is exactly what interviewers want to hear before you propose architecture. What Comes Next (And Why It’s Easy Now) Only after this reasoning does it make sense to talk about: Persistent storage Async delivery Streaming connections Partitioning strategies At this point, architecture choices are obvious , not arbitrary. Why This Approach Scores High in Interviews Interviewers are evaluating: How you reason under ambiguity Whether you surface hidden constraints Whether you understand failure modes They are not testing whether you know WhatsApp’s internals. This method shows: Structured thinking Calm problem decomposition Senior-level judgment Common Candidate Mistakes (Seen in This Question) Jumping to WebSockets without discussing durability Ignoring offline users Assuming message order “just works” Treating retries as harmless Talking about scale before correctness Every one of these mistakes is prevented by the checklist. Final Reinforcement: The Checklist (Again) Use this verbatim in interviews: Where does state live? When is it durable? Which steps are fast vs slow? What can fail independently? What defines correct order? What grows fastest under load? Final Mental Model Strong candidates design systems. Exceptional candidates design reasoning .

It is through these differences that our community experiences great successes and continued growth. When you're working with members of the community, this Code of Conduct will help steer your interactions and keep Python a positive, successful, and growing community. Our Community Members of the Python community are open, considerate, and respectful . Behaviours that reinforce these values contribute to a positive environment, and include: Being open. Members of the community are open to collaboration, whether it's on PEPs, patches, problems, or otherwise. Focusing on what is best for the community. We're respectful of the processes set forth in the community, and we work within them. Acknowledging time and effort. We're respectful of the volunteer efforts that permeate the Python community. We're thoughtful when addressing the efforts of others, keeping in mind that often times the labor was completed simply for the good of the community. Being respectful of differing viewpoints and experiences. We're receptive to constructive comments and criticism, as the experiences and skill sets of other members contribute to the whole of our efforts. Showing empathy towards other community members. We're attentive in our communications, whether in person or online, and we're tactful when approaching differing views. Being considerate. Members of the community are considerate of their peers -- other Python users. Being respectful. We're respectful of others, their positions, their skills, their commitments, and their efforts. Gracefully accepting constructive criticism. When we disagree, we are courteous in raising our issues. Using welcoming and inclusive language. We're accepting of all who wish to take part in our activities, fostering an environment where anyone can participate and everyone can make a difference. Our Standards Every member of our community has the right to have their identity respected. The Python community is dedicated to providing a positive experience for everyone, regardless of age, gender identity and expression, sexual orientation, disability, physical appearance, body size, ethnicity, nationality, race, or religion (or lack thereof), education, or socio-economic status.

Most of the time, you can write inline HTML directly into your posts. We support native Liquid tags and created some fun custom ones, too! Trying embedding a Tweet or GitHub issue in your post, using the complete URL: {% embed https://... %} . Links to unpublished posts are shareable for feedback/review. When you're ready to publish, set the published variable to true or click publish depending on the editor version, you're using Links to unpublished posts (drafts or scheduled posts) are shareable for feedback/review. These posts have a notice which reads "This URL is public but secret, so share at your own discretion." They are not visible in feeds or on your profile until published. description area in Twitter cards and open graph cards We have two editor versions . If you'd prefer to edit title and tags etc. as separate fields, switch to the "rich + markdown" option in Settings → Customization . Otherwise, continue: Front Matter Custom variables set for each post, located between the triple-dashed lines in your editor Here is a list of possibilities: title: the title of your article published: boolean that determines whether or not your article is published. tags: max of four tags, needs to be comma-separated canonical_url: link for the canonical version of the content cover_image: cover image for post, accepts a URL. The best size is 1000 x 420. series: post series name. ✍ Markdown Basics Below are some examples of commonly used markdown syntax. If you want to dive deeper, check out this cheat sheet. Bold & Italic Italics : *asterisks* or _underscores_ Bold : **double asterisks** or __double underscores__ Links I'm an inline link : [I'm an inline link](put-link-here) Anchored links (For things like a Table of Contents) ## Table Of Contents * [Chapter 1](#chapter-1) * [Chapter 2](#chapter-2) ### Chapter 1 <a name="chapter-1"></a> Inline Images When adding GIFs to posts and comments, please note that there is a limit of 200 megapixels per frame/page.  You can even add a caption using the HTML figcaption tag! Headings Add a heading to your post with this syntax: # One '#' for a h1 heading ## Two '#'s for a h2 heading ... ###### Six '#'s for a h6 heading Author Notes/Comments Add some hidden notes/comments to your article with this syntax: <!-- This won't show up in the content! --> Accessibility People access online content in all kinds of different ways, and there are a few things you can do to make your posts more easily understood by a broad range of users. You can find out more about web accessibility at W3C's Introduction to Web Accessibility , but there are two main ways you can make your posts more accessible: providing alternative descriptions of any images you use, and adding appropriate headings. Providing alternative descriptions for images Some users might not be able to see or easily process images that you use in your posts. Providing an alternative description for an image helps make sure that everyone can understand your post, whether they can see the image or not. When you upload an image in the editor, you will see the following text to copy and paste into your post:  Replace the "Image description" in square brackets with a description of your image - for example:  By doing this, if someone reads your post using an assistive device like a screen reader (which turns written content into spoken audio) they will hear the description you entered. Providing headings Headings provide an outline of your post to readers, including people who can't see the screen well. Many assistive technologies (like screen readers) allow users to skip directly to a particular heading, helping them find and understand the content of your post with ease. Headings can be added in levels 1 - 6 . Avoid using a level one heading (i.e., '# Heading text'). When you create a post, your post title automatically becomes a level one heading and serves a special role on the page, much like the headline of a newspaper article. Similar to how a newspaper article only has one headline, it can be confusing if multiple level one headings exist on a page. In your post content, start with level two headings for each section (e.g. '## Section heading text'), and increase the heading level by one when you'd like to add a sub-section, for example: ## Fun facts about sloths ### Speed Sloths move at a maximum speed of 0.27 km/h! 🌊 Liquid Tags We support native Liquid tags in our editor, but have created our own custom tags as well. A list of supported custom embeds appears below. To create a custom embed, use the complete URL: {% embed https://... %} Supported URL Embeds DEV Community Comment DEV Community Link DEV Community Link DEV Community Listing DEV Community Organization DEV Community Podcast Episode DEV Community Tag DEV Community User Profile asciinema CodePen CodeSandbox DotNetFiddle GitHub Gist, Issue or Repository Glitch Instagram JSFiddle JSitor Loom Kotlin Medium Next Tech Reddit Replit Slideshare Speaker Deck SoundCloud Spotify StackBlitz Stackery Stack Exchange or Stack Overflow Twitch Twitter Twitter timeline Wikipedia Vimeo YouTube Supported Non-URL Embeds Call To Action (CTA) {% cta link %} description {% endcta %} Provide a link that a user will be redirected to. The description will contain the label/description for the call to action. Details You can embed a details HTML element by using details, spoiler, or collapsible. The summary will be what the dropdown title displays. The content will be the text hidden behind the dropdown. This is great for when you want to hide text (i.e. answers to questions) behind a user action/intent (i.e. a click). {% details summary %} content {% enddetails %} {% spoiler summary %} content {% endspoiler %} {% collapsible summary %} content {% endcollapsible %} KaTex Place your mathematical expression within a KaTeX liquid block, as follows: {% katex %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} To render KaTeX inline add the "inline" option: {% katex inline %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} RunKit Put executable code within a runkit liquid block, as follows: {% runkit // hidden setup JavaScript code goes in this preamble area const hiddenVar = 42 %} // visible, reader-editable JavaScript code goes here console.log(hiddenVar) {% endrunkit %} Parsing Liquid Tags as a Code Example To parse Liquid tags as code, simply wrap it with a single backtick or triple backticks. `{% mytag %}{{ site.SOMETHING }}{% endmytag %}` One specific edge case is with using the raw tag. To properly escape it, use this format: `{% raw %}{{site.SOMETHING }} {% ``endraw`` %}` Common Gotchas Lists are written just like any other Markdown editor. If you're adding an image in between numbered list, though, be sure to tab the image, otherwise it'll restart the number of the list. Here's an example of what to do: Here's the Markdown cheatsheet again for reference.

Posted on Jan 12 Why Your Secret Sharing Tool Needs Post-Quantum Cryptography Today # security # cryptography # webdev # privacy The "Harvest Now, Decrypt Later" Threat Quantum computers capable of breaking RSA and ECC encryption don't exist yet. But here's the problem: adversaries are already collecting encrypted data today, planning to decrypt it once quantum computers arrive. For sensitive data that needs to remain confidential for years, this is a real threat. What is Post-Quantum Cryptography? Post-quantum cryptography (PQC) uses mathematical problems that are hard for both classical AND quantum computers to solve. In August 2024, NIST standardized three PQC algorithms: ML-KEM (Kyber) - Key encapsulation ML-DSA (Dilithium) - Digital signatures SLH-DSA (SPHINCS+) - Hash-based signatures Implementing PQC in a Web Application I recently added PQC support to NoTrust.now , a zero-knowledge secret sharing tool. Here's how: Key Exchange with ML-KEM-768 // Using crystals-kyber-js library import { MlKem768 } from ' crystals-kyber-js ' ; // Receiver generates keypair const [ publicKey , privateKey ] = await MlKem768 . generateKeyPair (); // Sender encapsulates a shared secret const [ ciphertext , sharedSecret ] = await MlKem768 . encapsulate ( publicKey ); // Receiver decapsulates to get the same shared secret const decryptedSecret = await MlKem768 . decapsulate ( ciphertext , privateKey ); Enter fullscreen mode Exit fullscreen mode Hybrid Approach For defense in depth, combine PQC with classical crypto: Generate ephemeral X25519 keypair (classical) Generate ephemeral ML-KEM-768 keypair (post-quantum) Combine both shared secrets: finalKey = HKDF(x25519Secret || kyberSecret) This ensures security even if one algorithm is broken. Try It Out You can test PQC secret sharing at NoTrust.now/createpqc . The encryption happens entirely in your browser - zero-knowledge architecture means the server never sees your plaintext.

Report Abuse Mohammad-Idrees Posted on Jan 13 Applying First-Principles Questioning to a Real Company Interview Question # career # interview # systemdesign Case Study: Designing a Chat System (Meta / WhatsApp–Style) This section answers a common follow-up interview request: “Okay, now apply this thinking to a real problem.” We will do exactly that — without jumping to tools or architectures first . The goal is not to “design WhatsApp,” but to demonstrate how interviewers expect you to think . The Interview Question (Realistic & Common) “Design a chat system like WhatsApp.” This is a real company interview question asked (in variants) at: Meta Uber Amazon Stripe Most candidates fail this question not because it’s hard, but because they start in the wrong place . What Most Candidates Do (Wrong Start) Typical opening: “We’ll use WebSockets” “We’ll use Kafka” “We’ll shard by user ID” This skips reasoning. A strong candidate pauses and applies the checklist. Applying the First-Principles Checklist Live We will apply the same five questions , in order, and show what problems naturally surface. 1. State “Where does state live? When is it durable?” Ask This Out Loud in the Interview What information must the chat system remember for it to function correctly? Identify Required State (No Design Yet) Users Conversations Messages Message delivery status Now ask: Which of this state must never be lost? Answer: Messages (core product) Conversation membership First-Principles Conclusion Messages must be persisted In-memory-only solutions are insufficient What the Interviewer Sees You identified correctness-critical state before touching architecture. 2. Time “How long does each step take?” Now we introduce time. Break the Chat Flow User sends message Message is stored Message is delivered to recipient(s) Ask: Which of these must be fast? Sending a message → must feel instant Delivery → may be delayed (offline users) Critical Question Does the sender wait for delivery confirmation? If yes: Latency depends on recipient availability If no: Sending and delivery are time-decoupled First-Principles Conclusion Message acceptance must be fast Delivery can happen later This naturally introduces asynchrony , without naming any tools. 3. Failure “What breaks independently?” Now assume failures — explicitly. Ask What happens if the system crashes after accepting a message but before delivery? Possible states: Message stored Recipient not notified yet Now ask: Can delivery be retried safely? This surfaces a key invariant: A message must not be delivered zero times or multiple times incorrectly. Failure Scenarios Discovered Duplicate delivery Message loss Inconsistent delivery status First-Principles Conclusion Message delivery must be idempotent Storage and delivery failures must be decoupled The interviewer now sees you understand distributed failure , not just happy paths. 4. Order “What defines correct sequence?” Now introduce multiple messages . Ask Does message order matter in a conversation? Answer: Yes — chat messages must appear in order Now ask the dangerous question: Does arrival order equal delivery order? In distributed systems: No guarantee Messages can: Be processed by different servers Experience different delays First-Principles Conclusion Ordering is part of correctness It must be explicitly modeled (e.g., sequence per conversation) This is a senior-level insight , derived from questioning alone. 5. Scale “What grows fastest under load?” Now — and only now — do we talk about scale. Ask As usage grows, what increases fastest? Likely answers: Number of messages Concurrent active connections Offline message backlog Now ask: What happens during spikes (e.g., group chats, viral events)? You discover: Hot conversations Uneven load Memory pressure from live connections First-Principles Conclusion The system must scale on messages , not users Load is not uniform What We Have Discovered (Before Any Design) Without choosing any tools, we now know: Messages must be durable Sending and delivery must be decoupled Failures must not cause duplicates or loss Ordering is a correctness requirement Message volume, not user count, dominates scale This is exactly what interviewers want to hear before you propose architecture. What Comes Next (And Why It’s Easy Now) Only after this reasoning does it make sense to talk about: Persistent storage Async delivery Streaming connections Partitioning strategies At this point, architecture choices are obvious , not arbitrary. Why This Approach Scores High in Interviews Interviewers are evaluating: How you reason under ambiguity Whether you surface hidden constraints Whether you understand failure modes They are not testing whether you know WhatsApp’s internals. This method shows: Structured thinking Calm problem decomposition Senior-level judgment Common Candidate Mistakes (Seen in This Question) Jumping to WebSockets without discussing durability Ignoring offline users Assuming message order “just works” Treating retries as harmless Talking about scale before correctness Every one of these mistakes is prevented by the checklist. Final Reinforcement: The Checklist (Again) Use this verbatim in interviews: Where does state live? When is it durable? Which steps are fast vs slow? What can fail independently? What defines correct order? What grows fastest under load? Final Mental Model Strong candidates design systems. Exceptional candidates design reasoning .

Report Abuse Behram Posted on Jan 12 How I built a "Magic Move" animation engine for Excalidraw from scratch published # webdev # react # animation # opensource I love Excalidraw for sketching system architectures. But sketches are static. When I want to show how a packet moves through a load balancer, or how a database shard splits, I have to wave my hands frantically or create 10 different slides. I wanted the ability to "Sketch Logic, Export Motion" . The Goal I didn't want a timeline editor (like After Effects). That's too much work for a simple diagram. I wanted "Keyless Animation" : Draw Frame 1 (The start state). Clone it to Frame 2 . Move elements to their new positions. The engine automatically figures out the transition. I built this engine using Next.js , Excalidraw , and Framer Motion . Here is a technical deep dive into how I implemented the logic. 1. The Core Logic: Diffing States The hardest part isn't the animation loop; it's the diffing . When we move from Frame A to Frame B , we identify elements by their stable IDs and categorize them into one of three buckets: Stable: The element exists in both frames (needs to morph/move). Entering: Exists in B but not A (needs to fade in). Exiting: Exists in A but not B (needs to fade out). I wrote a categorizeTransition utility that maps elements efficiently: // Simplified logic from src/utils/editor/transition-logic.ts export function categorizeTransition ( prevElements , currElements ) { const stable = []; const morphed = []; const entering = []; const exiting = []; const prevMap = new Map ( prevElements . map ( e => [ e . id , e ])); const currMap = new Map ( currElements . map ( e => [ e . id , e ])); // 1. Find Morphs (Stable) & Entering currElements . forEach ( curr => { if ( prevMap . has ( curr . id )) { const prev = prevMap . get ( curr . id ); // We separate "Stable" (identical) from "Morphed" (changed) // to optimize the render loop if ( areVisuallyIdentical ( prev , curr )) { stable . push ({ key : curr . id , element : curr }); } else { morphed . push ({ key : curr . id , start : prev , end : curr }); } } else { entering . push ({ key : curr . id , end : curr }); } }); // 2. Find Exiting prevElements . forEach ( prev => { if ( ! currMap . has ( prev . id )) { exiting . push ({ key : prev . id , start : prev }); } }); return { stable , morphed , entering , exiting }; } Enter fullscreen mode Exit fullscreen mode 2. Interpolating Properties For the "Morphed" elements, we need to calculate the intermediate state at any given progress (0.0 to 1.0). You can't just use simple linear interpolation for everything. Numbers (x, y, width): Linear works fine. Colors (strokeColor): You must convert Hex to RGBA, interpolate each channel, and convert back. Angles: You need "shortest path" interpolation. If an object is at 10 degrees and rotates to 350 degrees , linear interpolation goes the long way around. We want it to just rotate -20 degrees. // src/utils/smart-animation.ts const angleProgress = ( oldAngle , newAngle , progress ) => { let diff = newAngle - oldAngle ; // Normalize to -PI to +PI to find shortest direction while ( diff > Math . PI ) diff -= 2 * Math . PI ; while ( diff < - Math . PI ) diff += 2 * Math . PI ; return oldAngle + diff * progress ; }; Enter fullscreen mode Exit fullscreen mode 3. The Render Loop & Overlapping Phases Instead of CSS transitions (which are hard to sync for complex canvas repaints), I used a requestAnimationFrame loop in a React hook called useTransitionAnimation . A key "secret sauce" to making animations feel professional is overlap . If you play animations sequentially (Exit -> Move -> Enter), it feels robotic. I overlapped the phases so the scene feels alive: // Timeline Logic const exitEnd = hasExit ? 300 : 0 ; const morphStart = exitEnd ; const morphEnd = morphStart + 500 ; // [MAGIC TRICK] Start entering elements BEFORE the morph ends // This creates that "Apple Keynote" feel where things arrive // just as others are settling into place. const overlapDuration = 200 ; const enterStart = Math . max ( morphStart , morphEnd - overlapDuration ); Enter fullscreen mode Exit fullscreen mode 4. Making it feel "Physical" Linear movement ( progress = time / duration ) is boring. I implemented spring-based easing functions. Even though I'm manually calculating specific frames, I apply an easing curve to the progress value before feeding it into the interpolator. // Quartic Ease-Out Approximation for a "Heavy" feel const springEasing = ( t ) => { return 1 - Math . pow ( 1 - t , 4 ); }; Enter fullscreen mode Exit fullscreen mode This ensures that big architecture blocks "thud" into place with weight, rather than sliding around like ghosts. What's Next? I'm currently working on: Sub-step animations: Allowing you to click through bullet points within a single frame. Export to MP4: Recording the canvas stream directly to a video file. The project is live, and I built it to help developers communicate better. Try here: https://postara.io/ Free Stripe Promotion Code: postara Let me know what you think of the approach!

Report Abuse Hoang Le Posted on Jan 11 The Builds That Last Manifesto # productivity # programming # architecture # career Originally published on Builds That Last . I've been building and leading engineering teams for 15 years. Over 50 projects. Startups, enterprises, legacy systems, greenfield builds. Same pattern every time. Teams ship fast. Then they slow down. Not because engineers got lazy. Because the foundation was never there. At my company, we maintain systems 20+ years old. No documentation. No standards. When we ask stakeholders about business logic, they say "read the code". My teams sometimes decompile binary files just to understand what's inside. Debug at runtime because that's the only way to see how things work. Previous teams deployed code to AWS without committing to source control. Gone. This is what engineering looks like for most of us. Not the AI demos. Not the apps shipped in a weekend. The gap between posts and reality You'll see posts about vibe coding, AI-augmented development, shipping apps in hours. I'm not saying AI isn't real. I use these tools every day. The productivity gains are real. But there's a gap between what people post and what I see in actual projects. The posts show demos that work. Reality is production systems that break. The posts celebrate shipping fast. Reality is teams spending months paying back technical debt. The demo works. The demo always works. It's what comes after that separates software that lasts from software that collapses. The iceberg problem What you see is 20% above water. The shiny demos. The fast shipping. Vibe coding, agentic AI, apps built in hours. What you don't see is the 80% below: → Maintenance → Technical debt → Engineers connecting systems never meant to work together → Data inconsistencies accumulated over years → Teams spending days understanding what the previous developer was thinking That 80% is where my teams spend most of our time. And it's where the real lessons are. The speed trap I see this pattern repeat. A team starts fast. AI tools, modern stack, motivated engineers. First version ships in weeks. Everyone celebrates. Then users show up. Edge cases appear. The payment flow breaks. Data sync fails silently. Features that worked in demo crash under real load. Suddenly the team that was "moving fast" spends months fixing things. Not building new features. Just paying back debt from shipping without foundation. Leadership gets frustrated. "Why is the team slow now?" The team isn't slow. They're doing work that should have been done upfront. Speed without foundation creates the illusion of progress. Then reality catches up. Maintenance costs more than building Here's something most people don't think about until it's too late. Maintaining software costs more than building it from scratch. Think about repairing a house. You don't just fix the broken part. You investigate the structure. Remove old materials. Work around things that can't be changed. Then build the new thing. Software is the same. When you inherit a system without documentation, without standards, every change becomes an archaeology project. You spend more time understanding than building. The time you "save" by skipping foundation gets paid back with interest during maintenance. The AI paradox AI makes code generation 10x faster. That's real. AI also increases cognitive load by 30-40%. When AI generates code, someone still needs to verify it's secure. Check for edge cases. Understand the logic before shipping. Maintain it when something breaks. AI doesn't eliminate this work. It changes who's responsible for catching problems. Anthropic's CEO said 90% of their internal code is now AI-generated. The follow-up: "We're not replacing engineers". The 10% humans handle? That's the leverage zone. Architecture decisions. Debugging complex problems. Understanding why something should work, not just what it should do. AI is a turbo, not a robot. Good foundation? AI makes you faster at building good software. Bad foundation? AI makes you faster at building bad software. What this means for engineers The fundamentals matter more than ever. Everyone has access to AI now. The differentiator isn't who prompts better. It's who understands what they're building deeply enough to know when AI helps and when it hurts. Own your code. "The AI wrote it" isn't an excuse when something breaks at 2am. You shipped it. You're responsible. Read the code. Understand the logic. Ship with confidence. The 80% below water is where you build real skills. Legacy systems, maintenance, debugging. Not glamorous. But it's where you learn how software actually behaves. Don't avoid it. Embrace it. What this means for leaders You're only seeing 20% of what your team deals with. The demos work. Sprint reports look fine. But your team might be drowning in the 80% you don't see. The legacy code. Missing documentation. Tribal knowledge that walks out when someone leaves. Buying tools is easy. Training is hard. Teams that succeed with AI invested in foundation first. Standards, process, documentation. Then added AI. Teams that struggle added tools to existing chaos. Now they have faster chaos. Remove friction before adding speed. When you want to go faster, the instinct is to add more. More tools, more people, more pressure. Usually, the answer is to remove things. Remove blockers. Remove unnecessary process. Remove friction slowing your team down. The bottom line Real speed comes from clarity, not from typing faster. In the AI era, shipping is easy. Building to last is what matters. Those legacy systems with no documentation? They taught me more than any greenfield project. Not because they were well-built. Because they showed what happens when foundation is missing. Every time I build something new, I think about the engineer maintaining it in 10 years. Will they understand our decisions? Can they change things confidently? Or will they be stuck doing archaeology? That's what foundation means. Building for the people who come after. What's your experience with the 80% below water?

Due to time constraints in managing this program ourselves, we are not in a position to keep the program in-house. We are exploring other options, but do not have a timeline for a re-launch. While we are no longer able to offer monetary rewards at this time, we still highly value the security community's input and encourage you to continue reporting any vulnerabilities you may discover. Please send your findings to security@dev.to , and we will diligently investigate all reports. We remain committed to acknowledging significant contributions through our security hall of fame. We hope to launch a new reward program in the future. Your understanding and continued support in maintaining the security of our systems are deeply appreciated. Security Guidelines and Etiquette Please read and follow these guidelines prior to sending in any reports. 1. Do not test vulnerabilities in public. We ask that you do not attempt any vulnerabilities, rate-limiting tests, exploits, or any other security/bug-related findings if it will impact another community member. This means you should not leave comments on someone else’s post, send them messages via Connect, or otherwise, impact their experience on the platform. Note that we are open source and have documentation available if you're interested in setting up a dev environment for the purposes of testing. 2. Do not report similar issues or variations of the same issue in different reports. Please report any similar issues in a single report. It's better for both parties to have this information in one place where we can evaluate it all together. Please note any and all areas where your vulnerability might be relevant. You will not be penalized or receive a lower reward for streamlining your report in one place vs. spreading it across different areas. 3. The following domains are not eligible for our bounty program as they are hosted by or built on external services: jobs.dev.to (Recruitee) status.dev.to (Atlassian) shop.dev.to (Shopify) docs.dev.to (Netlify) storybook.dev.to (Netlify) We've listed the service provider of each of these domains so that you might contact them if you wish to report the vulnerability you found. 4. DoS (Denial of Service) vulnerabilities should not be tested for more than a span of 5 minutes. Be courteous and reasonable when testing any endpoints on dev.to as this may interfere with our monitoring. If we discover that you are testing DoS disruptively for prolonged periods of time, we may restrict your award, block your IP address, or remove your eligibility to participate in the program. 5. Please be patient with us after sending in your report. We’d appreciate it if you avoid messaging us to ask about the status of your report. Our team will get back to you only if your contribution is significant enough to be included in our hall of fame.

Report Abuse Behram Posted on Jan 12 How I built a "Magic Move" animation engine for Excalidraw from scratch published # webdev # react # animation # opensource I love Excalidraw for sketching system architectures. But sketches are static. When I want to show how a packet moves through a load balancer, or how a database shard splits, I have to wave my hands frantically or create 10 different slides. I wanted the ability to "Sketch Logic, Export Motion" . The Goal I didn't want a timeline editor (like After Effects). That's too much work for a simple diagram. I wanted "Keyless Animation" : Draw Frame 1 (The start state). Clone it to Frame 2 . Move elements to their new positions. The engine automatically figures out the transition. I built this engine using Next.js , Excalidraw , and Framer Motion . Here is a technical deep dive into how I implemented the logic. 1. The Core Logic: Diffing States The hardest part isn't the animation loop; it's the diffing . When we move from Frame A to Frame B , we identify elements by their stable IDs and categorize them into one of three buckets: Stable: The element exists in both frames (needs to morph/move). Entering: Exists in B but not A (needs to fade in). Exiting: Exists in A but not B (needs to fade out). I wrote a categorizeTransition utility that maps elements efficiently: // Simplified logic from src/utils/editor/transition-logic.ts export function categorizeTransition ( prevElements , currElements ) { const stable = []; const morphed = []; const entering = []; const exiting = []; const prevMap = new Map ( prevElements . map ( e => [ e . id , e ])); const currMap = new Map ( currElements . map ( e => [ e . id , e ])); // 1. Find Morphs (Stable) & Entering currElements . forEach ( curr => { if ( prevMap . has ( curr . id )) { const prev = prevMap . get ( curr . id ); // We separate "Stable" (identical) from "Morphed" (changed) // to optimize the render loop if ( areVisuallyIdentical ( prev , curr )) { stable . push ({ key : curr . id , element : curr }); } else { morphed . push ({ key : curr . id , start : prev , end : curr }); } } else { entering . push ({ key : curr . id , end : curr }); } }); // 2. Find Exiting prevElements . forEach ( prev => { if ( ! currMap . has ( prev . id )) { exiting . push ({ key : prev . id , start : prev }); } }); return { stable , morphed , entering , exiting }; } Enter fullscreen mode Exit fullscreen mode 2. Interpolating Properties For the "Morphed" elements, we need to calculate the intermediate state at any given progress (0.0 to 1.0). You can't just use simple linear interpolation for everything. Numbers (x, y, width): Linear works fine. Colors (strokeColor): You must convert Hex to RGBA, interpolate each channel, and convert back. Angles: You need "shortest path" interpolation. If an object is at 10 degrees and rotates to 350 degrees , linear interpolation goes the long way around. We want it to just rotate -20 degrees. // src/utils/smart-animation.ts const angleProgress = ( oldAngle , newAngle , progress ) => { let diff = newAngle - oldAngle ; // Normalize to -PI to +PI to find shortest direction while ( diff > Math . PI ) diff -= 2 * Math . PI ; while ( diff < - Math . PI ) diff += 2 * Math . PI ; return oldAngle + diff * progress ; }; Enter fullscreen mode Exit fullscreen mode 3. The Render Loop & Overlapping Phases Instead of CSS transitions (which are hard to sync for complex canvas repaints), I used a requestAnimationFrame loop in a React hook called useTransitionAnimation . A key "secret sauce" to making animations feel professional is overlap . If you play animations sequentially (Exit -> Move -> Enter), it feels robotic. I overlapped the phases so the scene feels alive: // Timeline Logic const exitEnd = hasExit ? 300 : 0 ; const morphStart = exitEnd ; const morphEnd = morphStart + 500 ; // [MAGIC TRICK] Start entering elements BEFORE the morph ends // This creates that "Apple Keynote" feel where things arrive // just as others are settling into place. const overlapDuration = 200 ; const enterStart = Math . max ( morphStart , morphEnd - overlapDuration ); Enter fullscreen mode Exit fullscreen mode 4. Making it feel "Physical" Linear movement ( progress = time / duration ) is boring. I implemented spring-based easing functions. Even though I'm manually calculating specific frames, I apply an easing curve to the progress value before feeding it into the interpolator. // Quartic Ease-Out Approximation for a "Heavy" feel const springEasing = ( t ) => { return 1 - Math . pow ( 1 - t , 4 ); }; Enter fullscreen mode Exit fullscreen mode This ensures that big architecture blocks "thud" into place with weight, rather than sliding around like ghosts. What's Next? I'm currently working on: Sub-step animations: Allowing you to click through bullet points within a single frame. Export to MP4: Recording the canvas stream directly to a video file. The project is live, and I built it to help developers communicate better. Try here: https://postara.io/ Free Stripe Promotion Code: postara Let me know what you think of the approach!

Report Abuse Mohammad-Idrees Posted on Jan 13 Applying First-Principles Questioning to a Real Company Interview Question # career # interview # systemdesign Case Study: Designing a Chat System (Meta / WhatsApp–Style) This section answers a common follow-up interview request: “Okay, now apply this thinking to a real problem.” We will do exactly that — without jumping to tools or architectures first . The goal is not to “design WhatsApp,” but to demonstrate how interviewers expect you to think . The Interview Question (Realistic & Common) “Design a chat system like WhatsApp.” This is a real company interview question asked (in variants) at: Meta Uber Amazon Stripe Most candidates fail this question not because it’s hard, but because they start in the wrong place . What Most Candidates Do (Wrong Start) Typical opening: “We’ll use WebSockets” “We’ll use Kafka” “We’ll shard by user ID” This skips reasoning. A strong candidate pauses and applies the checklist. Applying the First-Principles Checklist Live We will apply the same five questions , in order, and show what problems naturally surface. 1. State “Where does state live? When is it durable?” Ask This Out Loud in the Interview What information must the chat system remember for it to function correctly? Identify Required State (No Design Yet) Users Conversations Messages Message delivery status Now ask: Which of this state must never be lost? Answer: Messages (core product) Conversation membership First-Principles Conclusion Messages must be persisted In-memory-only solutions are insufficient What the Interviewer Sees You identified correctness-critical state before touching architecture. 2. Time “How long does each step take?” Now we introduce time. Break the Chat Flow User sends message Message is stored Message is delivered to recipient(s) Ask: Which of these must be fast? Sending a message → must feel instant Delivery → may be delayed (offline users) Critical Question Does the sender wait for delivery confirmation? If yes: Latency depends on recipient availability If no: Sending and delivery are time-decoupled First-Principles Conclusion Message acceptance must be fast Delivery can happen later This naturally introduces asynchrony , without naming any tools. 3. Failure “What breaks independently?” Now assume failures — explicitly. Ask What happens if the system crashes after accepting a message but before delivery? Possible states: Message stored Recipient not notified yet Now ask: Can delivery be retried safely? This surfaces a key invariant: A message must not be delivered zero times or multiple times incorrectly. Failure Scenarios Discovered Duplicate delivery Message loss Inconsistent delivery status First-Principles Conclusion Message delivery must be idempotent Storage and delivery failures must be decoupled The interviewer now sees you understand distributed failure , not just happy paths. 4. Order “What defines correct sequence?” Now introduce multiple messages . Ask Does message order matter in a conversation? Answer: Yes — chat messages must appear in order Now ask the dangerous question: Does arrival order equal delivery order? In distributed systems: No guarantee Messages can: Be processed by different servers Experience different delays First-Principles Conclusion Ordering is part of correctness It must be explicitly modeled (e.g., sequence per conversation) This is a senior-level insight , derived from questioning alone. 5. Scale “What grows fastest under load?” Now — and only now — do we talk about scale. Ask As usage grows, what increases fastest? Likely answers: Number of messages Concurrent active connections Offline message backlog Now ask: What happens during spikes (e.g., group chats, viral events)? You discover: Hot conversations Uneven load Memory pressure from live connections First-Principles Conclusion The system must scale on messages , not users Load is not uniform What We Have Discovered (Before Any Design) Without choosing any tools, we now know: Messages must be durable Sending and delivery must be decoupled Failures must not cause duplicates or loss Ordering is a correctness requirement Message volume, not user count, dominates scale This is exactly what interviewers want to hear before you propose architecture. What Comes Next (And Why It’s Easy Now) Only after this reasoning does it make sense to talk about: Persistent storage Async delivery Streaming connections Partitioning strategies At this point, architecture choices are obvious , not arbitrary. Why This Approach Scores High in Interviews Interviewers are evaluating: How you reason under ambiguity Whether you surface hidden constraints Whether you understand failure modes They are not testing whether you know WhatsApp’s internals. This method shows: Structured thinking Calm problem decomposition Senior-level judgment Common Candidate Mistakes (Seen in This Question) Jumping to WebSockets without discussing durability Ignoring offline users Assuming message order “just works” Treating retries as harmless Talking about scale before correctness Every one of these mistakes is prevented by the checklist. Final Reinforcement: The Checklist (Again) Use this verbatim in interviews: Where does state live? When is it durable? Which steps are fast vs slow? What can fail independently? What defines correct order? What grows fastest under load? Final Mental Model Strong candidates design systems. Exceptional candidates design reasoning .

Report Abuse Yuil Tripathee Posted on Jun 6, 2024 So I tried Odoo for the first time # webdev # erp # beginners # odoo From web developer's viewpoint, I'm going to setup Odoo for the first time. It is going to installed on my local computer (Ubuntu 22.04) and the installation will be from community edition. Prerequisites Git, Python (3.10+), Pip and basics (IDEs and stuff) PostgreSQL database (can be community edition) Initial steps This is coming from Odoo's official documentation. Fork the GitHub repo for the community edition. Create a new postgres user. Odoo does not accept postgres default user. sudo -u postgres createuser -d -R -S $USER createdb $USER Enter fullscreen mode Exit fullscreen mode Running Odoo for the first time The two new databases created on PostgreSQL are: $USER whatever your username is and the other one called mydb . Run this command after you clone the Odoo repo and cd inside. python3 odoo-bin --addons-path = addons -d mydb Enter fullscreen mode Exit fullscreen mode After the server has started (the INFO log odoo.modules.loading: Modules loaded. is printed), open http://localhost:8069 in a web browser and log into the Odoo database with the base administrator account: use admin as the email and, again, admin as the password. Check the database schema I ran the ERD for database tool in pgAdmin to inspect the database design for the Odoo community base platform. From the start there are 114 tables linked in a mesh. So, I chose to dig into the database structure a bit further. Findings Odoo's database model is quite mature as of Version 17 and incorporable to wide contextual range. The database structure is monolith. Therefore, decoupling into possible micro-services would be a good prospect as some modules requires scaling different than the other. You can refer to Server Framework 101 guide in order to develop your own modules.

Report Abuse Rashi Posted on Oct 2, 2025 The Next Shift in Development: From Coding to AI Orchestration # ai # career # softwaredevelopment The Changing Role of Developers The craft of software development has always evolved with the tools of the era. From assembly to higher-level languages, from waterfall to agile, from on-prem servers to the cloud — developers adapt. The next shift, however, isn’t just about new languages or platforms. It’s about how developers interact with AI as both a tool and a collaborator . We’re entering an era where developers spend less time typing raw code and more time guiding, validating, and governing the work AI generates. 1. AI Orchestration Becomes a Core Skill Instead of writing every line by hand, developers will orchestrate multiple AI systems . This means: Combining specialized AI models for tasks like code generation, testing, and deployment. Building workflows where AI outputs feed into each other. Managing context so AI has the right inputs at the right time. It’s less like writing a single function and more like conducting an orchestra — ensuring all the “instruments” play together smoothly. 2. Prompt Engineering as the New Debugging Prompts are the new interface. Just like developers once debugged code line by line, they’ll debug prompts to get reliable results. The difference is: Instead of fixing syntax errors, they’ll tweak language and context. Instead of compiler errors, they’ll interpret ambiguous or inconsistent AI output. Instead of a test suite, they’ll use structured evaluations of prompts across different scenarios. Knowing how to talk to AI effectively is quickly becoming as important as knowing a programming language. 3. Reviewing and Validating AI Output AI is powerful, but it’s not infallible. Developers will increasingly become validators : Checking whether AI-generated code is correct, secure, and maintainable. Identifying hallucinations or inaccuracies in AI-generated documentation or design suggestions. Embedding automated validation checks to catch mistakes before they slip into production. Think of it as a shift from code author to code reviewer at scale . 4. AI Governance: A Developer Responsibility Governance won’t be just for compliance officers. Developers themselves will help enforce responsible AI use : Ensuring models don’t leak sensitive data. Auditing decisions made by AI-assisted systems. Documenting and explaining why certain AI-driven choices were made. Building “guardrails” into applications so AI stays within safe and ethical boundaries. Governance will be a shared responsibility — and developers will play a frontline role. The Developer’s Future: Less Typing, More Thinking The traditional image of a developer hammering out thousands of lines of code is fading. Instead, the role is becoming more strategic, oversight-driven, and interdisciplinary . Developers will still code, of course — but increasingly, they’ll: Guide AI systems with clarity. Ensure quality and correctness of outputs. Integrate AI tools responsibly into products. This shift may feel unfamiliar, but it echoes every evolution before: from machine code to modern frameworks, from local servers to the cloud. Each step required developers to let go of some old tasks and embrace new ones. The difference this time? We’re not just adopting tools — we’re collaborating with intelligence.

Report Abuse Mohammad-Idrees Posted on Jan 13 Applying First-Principles Questioning to a Real Company Interview Question # career # interview # systemdesign Case Study: Designing a Chat System (Meta / WhatsApp–Style) This section answers a common follow-up interview request: “Okay, now apply this thinking to a real problem.” We will do exactly that — without jumping to tools or architectures first . The goal is not to “design WhatsApp,” but to demonstrate how interviewers expect you to think . The Interview Question (Realistic & Common) “Design a chat system like WhatsApp.” This is a real company interview question asked (in variants) at: Meta Uber Amazon Stripe Most candidates fail this question not because it’s hard, but because they start in the wrong place . What Most Candidates Do (Wrong Start) Typical opening: “We’ll use WebSockets” “We’ll use Kafka” “We’ll shard by user ID” This skips reasoning. A strong candidate pauses and applies the checklist. Applying the First-Principles Checklist Live We will apply the same five questions , in order, and show what problems naturally surface. 1. State “Where does state live? When is it durable?” Ask This Out Loud in the Interview What information must the chat system remember for it to function correctly? Identify Required State (No Design Yet) Users Conversations Messages Message delivery status Now ask: Which of this state must never be lost? Answer: Messages (core product) Conversation membership First-Principles Conclusion Messages must be persisted In-memory-only solutions are insufficient What the Interviewer Sees You identified correctness-critical state before touching architecture. 2. Time “How long does each step take?” Now we introduce time. Break the Chat Flow User sends message Message is stored Message is delivered to recipient(s) Ask: Which of these must be fast? Sending a message → must feel instant Delivery → may be delayed (offline users) Critical Question Does the sender wait for delivery confirmation? If yes: Latency depends on recipient availability If no: Sending and delivery are time-decoupled First-Principles Conclusion Message acceptance must be fast Delivery can happen later This naturally introduces asynchrony , without naming any tools. 3. Failure “What breaks independently?” Now assume failures — explicitly. Ask What happens if the system crashes after accepting a message but before delivery? Possible states: Message stored Recipient not notified yet Now ask: Can delivery be retried safely? This surfaces a key invariant: A message must not be delivered zero times or multiple times incorrectly. Failure Scenarios Discovered Duplicate delivery Message loss Inconsistent delivery status First-Principles Conclusion Message delivery must be idempotent Storage and delivery failures must be decoupled The interviewer now sees you understand distributed failure , not just happy paths. 4. Order “What defines correct sequence?” Now introduce multiple messages . Ask Does message order matter in a conversation? Answer: Yes — chat messages must appear in order Now ask the dangerous question: Does arrival order equal delivery order? In distributed systems: No guarantee Messages can: Be processed by different servers Experience different delays First-Principles Conclusion Ordering is part of correctness It must be explicitly modeled (e.g., sequence per conversation) This is a senior-level insight , derived from questioning alone. 5. Scale “What grows fastest under load?” Now — and only now — do we talk about scale. Ask As usage grows, what increases fastest? Likely answers: Number of messages Concurrent active connections Offline message backlog Now ask: What happens during spikes (e.g., group chats, viral events)? You discover: Hot conversations Uneven load Memory pressure from live connections First-Principles Conclusion The system must scale on messages , not users Load is not uniform What We Have Discovered (Before Any Design) Without choosing any tools, we now know: Messages must be durable Sending and delivery must be decoupled Failures must not cause duplicates or loss Ordering is a correctness requirement Message volume, not user count, dominates scale This is exactly what interviewers want to hear before you propose architecture. What Comes Next (And Why It’s Easy Now) Only after this reasoning does it make sense to talk about: Persistent storage Async delivery Streaming connections Partitioning strategies At this point, architecture choices are obvious , not arbitrary. Why This Approach Scores High in Interviews Interviewers are evaluating: How you reason under ambiguity Whether you surface hidden constraints Whether you understand failure modes They are not testing whether you know WhatsApp’s internals. This method shows: Structured thinking Calm problem decomposition Senior-level judgment Common Candidate Mistakes (Seen in This Question) Jumping to WebSockets without discussing durability Ignoring offline users Assuming message order “just works” Treating retries as harmless Talking about scale before correctness Every one of these mistakes is prevented by the checklist. Final Reinforcement: The Checklist (Again) Use this verbatim in interviews: Where does state live? When is it durable? Which steps are fast vs slow? What can fail independently? What defines correct order? What grows fastest under load? Final Mental Model Strong candidates design systems. Exceptional candidates design reasoning .

Report Abuse joe-re Posted on Jan 12 I Built a Desktop App to Supercharge My TMUX + Claude Code Workflow # claudecode # tauri # productivity # tmux Background Until recently, I was primarily using Cursor for AI-assisted coding. The editor-centric AI integration worked really well with my development style—it made the feedback loop smooth when AI-generated code didn't match my intentions, whether I needed to manually fix it or provide additional instructions. But everything changed when Opus 4.5 was released in late November last year. Opus 4.5 delivers outputs that match my expectations far better than any previous model. Claude Code's CUI-first design also feels natural to my workflow. Now, Claude Code has become the center of my development process. I've locked in Opus 4.5 as my daily driver. I typically run multiple Claude Code sessions simultaneously—across different projects or multiple branches using git worktree. Managing notifications and checking outputs across these sessions is critical. I was using OS notifications to check in whenever changes happened, but I kept missing them. I wanted something better. So I built an app to streamline my workflow. What I Built eyes-on-claude-code It's a cross-platform desktop application built with Tauri . I've only tested it on macOS (my daily environment), but the codebase is designed to support Linux as well. My Environment & Workflow This app is primarily designed to optimize my own workflow, so the features reflect my environment and habits. I develop using Ghostty + tmux . My typical workflow looks like this: Draft ideas and design in Markdown Give instructions to Claude Code (using Plan mode for larger tasks) Review the diff of generated code, then provide additional instructions or continue Features Multi-Session Monitoring Dashboard The dashboard monitors Claude Code sessions by receiving events through hooks configured in the global settings.json . Since I keep this running during development, I designed it with a minimal, non-intrusive UI. Always-on-top mode (optional) ensures the window doesn't get buried under other apps—so you never miss a notification. Transparency settings let you configure opacity separately for active and inactive states. When inactive, you can make it nearly invisible so it doesn't get in the way. It's there in the top-right corner, barely visible. Status Display & Sound Notifications Sessions are displayed with one of four states: State Meaning Display Active Claude is working 🟢 WaitingPermission Waiting for permission approval 🔐 WaitingInput Waiting for user input (idle) ⏳ Completed Response complete ✅ Sound effects play on state changes (can be toggled off): Waiting (Permission/Input) : Alert tone (two low beeps) Completed : Completion chime (ascending two-note sound) I'm planning to add volume control and custom commands in the future—like using say to speak or playing music on completion 🎵 Git-Based Diff Viewer I usually review AI-generated changes using difit . I wanted to integrate that same flow into this app, so you can launch difit directly on changed files. Huge thanks to the difit team for building such a great tool! tmux Integration When developing, I use tmux panes and tabs to manage multiple windows. My typical setup is Claude Code on the left half, and server/commands on the right. When working across multiple projects or branches via git worktree, it's frustrating to hunt for which tmux tab has Claude Code running. So I added a tmux mirror view that lets you quickly check results and give simple instructions without switching tabs. How It Works The app uses Claude Code hooks to determine session status based on which hooks fire. Event Flow I didn't want to introduce complexity with an intermediate server for inter-process communication. So I went with a simple approach: hooks write to log files, and the app watches those files. Hooks write logs to a temporary directory ( .local/eocc/logs ), which the app monitors. Since Claude Code runs in a terminal, hooks can access terminal environment paths. This lets me grab tmux and npx paths from within hooks and pass them to the app. Mapping Hooks to Status Claude Code provides these hook events: https://code.claude.com/docs/hooks-guide Here's how I map them to session states: Event Usage Session State session_start (startup/resume) Start a session Active session_end End a session Remove session notification (permission_prompt) Waiting for approval WaitingPermission notification (idle_prompt) Waiting for input WaitingInput stop Response completed Completed post_tool_use After tool execution Active user_prompt_submit Prompt submitted Active Conclusion I've only been using Claude Code as my primary tool for about two months, and I expect my workflow will keep evolving. Thanks to AI, I can quickly build and adapt tools like this—which is exactly what makes this era so exciting. If your workflow is similar to mine, give it a try! I'd love to hear your feedback.

Report Abuse Behram Posted on Jan 12 How I built a "Magic Move" animation engine for Excalidraw from scratch published # webdev # react # animation # opensource I love Excalidraw for sketching system architectures. But sketches are static. When I want to show how a packet moves through a load balancer, or how a database shard splits, I have to wave my hands frantically or create 10 different slides. I wanted the ability to "Sketch Logic, Export Motion" . The Goal I didn't want a timeline editor (like After Effects). That's too much work for a simple diagram. I wanted "Keyless Animation" : Draw Frame 1 (The start state). Clone it to Frame 2 . Move elements to their new positions. The engine automatically figures out the transition. I built this engine using Next.js , Excalidraw , and Framer Motion . Here is a technical deep dive into how I implemented the logic. 1. The Core Logic: Diffing States The hardest part isn't the animation loop; it's the diffing . When we move from Frame A to Frame B , we identify elements by their stable IDs and categorize them into one of three buckets: Stable: The element exists in both frames (needs to morph/move). Entering: Exists in B but not A (needs to fade in). Exiting: Exists in A but not B (needs to fade out). I wrote a categorizeTransition utility that maps elements efficiently: // Simplified logic from src/utils/editor/transition-logic.ts export function categorizeTransition ( prevElements , currElements ) { const stable = []; const morphed = []; const entering = []; const exiting = []; const prevMap = new Map ( prevElements . map ( e => [ e . id , e ])); const currMap = new Map ( currElements . map ( e => [ e . id , e ])); // 1. Find Morphs (Stable) & Entering currElements . forEach ( curr => { if ( prevMap . has ( curr . id )) { const prev = prevMap . get ( curr . id ); // We separate "Stable" (identical) from "Morphed" (changed) // to optimize the render loop if ( areVisuallyIdentical ( prev , curr )) { stable . push ({ key : curr . id , element : curr }); } else { morphed . push ({ key : curr . id , start : prev , end : curr }); } } else { entering . push ({ key : curr . id , end : curr }); } }); // 2. Find Exiting prevElements . forEach ( prev => { if ( ! currMap . has ( prev . id )) { exiting . push ({ key : prev . id , start : prev }); } }); return { stable , morphed , entering , exiting }; } Enter fullscreen mode Exit fullscreen mode 2. Interpolating Properties For the "Morphed" elements, we need to calculate the intermediate state at any given progress (0.0 to 1.0). You can't just use simple linear interpolation for everything. Numbers (x, y, width): Linear works fine. Colors (strokeColor): You must convert Hex to RGBA, interpolate each channel, and convert back. Angles: You need "shortest path" interpolation. If an object is at 10 degrees and rotates to 350 degrees , linear interpolation goes the long way around. We want it to just rotate -20 degrees. // src/utils/smart-animation.ts const angleProgress = ( oldAngle , newAngle , progress ) => { let diff = newAngle - oldAngle ; // Normalize to -PI to +PI to find shortest direction while ( diff > Math . PI ) diff -= 2 * Math . PI ; while ( diff < - Math . PI ) diff += 2 * Math . PI ; return oldAngle + diff * progress ; }; Enter fullscreen mode Exit fullscreen mode 3. The Render Loop & Overlapping Phases Instead of CSS transitions (which are hard to sync for complex canvas repaints), I used a requestAnimationFrame loop in a React hook called useTransitionAnimation . A key "secret sauce" to making animations feel professional is overlap . If you play animations sequentially (Exit -> Move -> Enter), it feels robotic. I overlapped the phases so the scene feels alive: // Timeline Logic const exitEnd = hasExit ? 300 : 0 ; const morphStart = exitEnd ; const morphEnd = morphStart + 500 ; // [MAGIC TRICK] Start entering elements BEFORE the morph ends // This creates that "Apple Keynote" feel where things arrive // just as others are settling into place. const overlapDuration = 200 ; const enterStart = Math . max ( morphStart , morphEnd - overlapDuration ); Enter fullscreen mode Exit fullscreen mode 4. Making it feel "Physical" Linear movement ( progress = time / duration ) is boring. I implemented spring-based easing functions. Even though I'm manually calculating specific frames, I apply an easing curve to the progress value before feeding it into the interpolator. // Quartic Ease-Out Approximation for a "Heavy" feel const springEasing = ( t ) => { return 1 - Math . pow ( 1 - t , 4 ); }; Enter fullscreen mode Exit fullscreen mode This ensures that big architecture blocks "thud" into place with weight, rather than sliding around like ghosts. What's Next? I'm currently working on: Sub-step animations: Allowing you to click through bullet points within a single frame. Export to MP4: Recording the canvas stream directly to a video file. The project is live, and I built it to help developers communicate better. Try here: https://postara.io/ Free Stripe Promotion Code: postara Let me know what you think of the approach!

Report Abuse Arsene Muyen Lee Posted on Jan 13 I'm a Developer Who Can't Market - So I Built an AI to Do It For Me # ai # productivity # showdev # opensource TL;DR : I'm a technical founder with zero marketing experience. Social media was killing my productivity. So I hooked up Claude Code + Playwright browser automation to manage marketing for me. Here's my journey from suffering to automation. The Problem: Technical Founder, Marketing Nightmare I've spent 20+ years writing code. I can architect systems, debug race conditions, and ship features. But marketing? I'm completely lost. I'm building ProofMi , an app that helps artists prove their photos are real (not AI-generated). The product is straightforward. Getting people to know about it? Absolute torture. My marketing "strategy" looked like this: Open Twitter, stare at blank compose box Type something, delete it, type again Finally post something awkward Open Reddit, realize I need a different tone Rewrite everything Open LinkedIn, professional-ify the language (whatever that means) Repeat for TikTok, Instagram... Forget what I posted where Miss all the comments Feel guilty about not "engaging" Burnout I'm a developer. I should be building features, not wrestling with social media tabs. The Breaking Point: Playwright MCP I was already using Claude Code for development. One day I needed to test something in a browser and discovered the Playwright MCP - Claude Code could literally control a browser. Me: "Navigate to this page and fill out the form" Claude: *opens browser, fills fields, clicks submit* Enter fullscreen mode Exit fullscreen mode That's when it hit me: What if Claude Code could manage my social media through browser automation? Not just posting - the whole workflow. Opening platforms, writing posts, copying links, even setting up API credentials. All the tedious clicking I hated. The Technical Journey Attempt 1: Pure Browser Automation My first thought was simple - just have Claude automate browser clicks: Me: "Go to Twitter and post about my new feature" Claude: *navigates to twitter.com* Claude: *clicks compose* Claude: *types post* Claude: *clicks post* Enter fullscreen mode Exit fullscreen mode It worked! But it was slow and brittle. Every time Twitter changed their UI, everything broke. Attempt 2: Postiz + MCP Then I found Postiz - an open-source social media scheduler (like Hootsuite, but free). The beautiful part? It has a built-in MCP server. MCP (Model Context Protocol) is how Claude Code talks to external services. Instead of clicking through browser UIs, Claude could call Postiz's API directly: http://localhost:3000/mcp/{your-api-key} Enter fullscreen mode Exit fullscreen mode Now Claude can: postiz_list_integrations - See connected accounts postiz_create_post - Schedule posts postiz_list_posts - View scheduled content postiz_delete_post - Remove scheduled posts Much cleaner than browser clicks. The Recursive Part: Setting Up APIs with AI But wait - to connect Postiz to Twitter, I needed Twitter API credentials. That meant: Creating a developer account Making a project and app Configuring OAuth settings Setting callback URLs Lots of clicking. Lots of forms. So I asked Claude to do it using Playwright browser automation: Me: "Set up the Twitter Developer API for me" Claude: *navigates to developer.x.com* Claude: *fills out developer application* Claude: *creates project* Claude: *configures OAuth* Claude: *saves API keys to my credentials file* Claude: "Done. Keys are saved." Enter fullscreen mode Exit fullscreen mode The AI was setting up API keys so it could post to social media. Turtles all the way down. My Workflow Now Before (suffering): 1. Context switch from coding 2. Open 5 browser tabs 3. Write 5 different versions of the same message 4. Post manually to each platform 5. Track in a spreadsheet I never update 6. Miss comments for days 7. Feel constant guilt 8. Zero consistency Enter fullscreen mode Exit fullscreen mode After (automated): Me: "Post about the new verification feature. Twitter should be casual, Reddit should ask for feedback" Claude: "Done. Here are the links: - Twitter: https://x.com/proofmiapp/status/... - Reddit: https://reddit.com/r/indiedev/..." Enter fullscreen mode Exit fullscreen mode Same reach. Zero suffering. The Setup (If You Want to Try) 1. Run Postiz Locally git clone https://github.com/gitroomhq/postiz-app cd postiz-app docker-compose -f docker-compose.dev.yaml up -d pnpm install pnpm run prisma-db-push pnpm run dev Enter fullscreen mode Exit fullscreen mode PostgreSQL, Redis, Temporal - all running. Frontend on 4200, backend on 3000. 2. Get Your Postiz API Key Go to Settings > API in the Postiz UI, create an API key. 3. Add MCP to Claude Code In ~/.claude.json : { "mcpServers" : { "postiz" : { "type" : "url" , "url" : "http://localhost:3000/mcp/YOUR_API_KEY" } } } Enter fullscreen mode Exit fullscreen mode 4. Connect Your Social Accounts Use Postiz's UI to connect Twitter, Reddit, LinkedIn, etc. Or ask Claude to do it with Playwright browser automation. What I Learned 1. Browser Automation is Underrated Playwright MCP is incredibly powerful for one-time setup tasks. Instead of manually clicking through OAuth flows, Claude can do it all. It's like having an intern who never gets tired of forms. 2. MCP Changes Everything The Model Context Protocol turns Claude Code from a coding assistant into a general automation platform. Any service with an MCP server becomes a natural language interface. 3. Open Source Wins Postiz being open source meant: Run locally (no SaaS fees) Inspect how their MCP works Potentially contribute back No data leaving my machine 4. Marketing Can Be Systematic I always thought marketing required "creativity" I didn't have. Turns out, most of it is just: Consistent posting Platform-appropriate formatting Tracking what works All of which can be automated or assisted by AI. The Meta Irony I'm using AI to: Market an app that detects AI fraud Set up API keys for AI tools Write posts about using AI Even write this article The snake is eating its tail and I love it. What's Next Engagement automation - "Reply to comments on yesterday's posts" Scheduled campaigns - "Post this series over the next week" Analytics - "Which posts performed best?" Content suggestions - "What should I post about today based on what's trending?" Try It Yourself The full stack: Postiz - Open source social scheduler Claude Code - AI coding assistant with MCP support Playwright MCP - Browser automation for setup tasks If you're a developer who hates marketing as much as I do, this approach might save your sanity. What repetitive task are you still doing manually that could be delegated to AI?

Report Abuse joe-re Posted on Jan 12 I Built a Desktop App to Supercharge My TMUX + Claude Code Workflow # claudecode # tauri # productivity # tmux Background Until recently, I was primarily using Cursor for AI-assisted coding. The editor-centric AI integration worked really well with my development style—it made the feedback loop smooth when AI-generated code didn't match my intentions, whether I needed to manually fix it or provide additional instructions. But everything changed when Opus 4.5 was released in late November last year. Opus 4.5 delivers outputs that match my expectations far better than any previous model. Claude Code's CUI-first design also feels natural to my workflow. Now, Claude Code has become the center of my development process. I've locked in Opus 4.5 as my daily driver. I typically run multiple Claude Code sessions simultaneously—across different projects or multiple branches using git worktree. Managing notifications and checking outputs across these sessions is critical. I was using OS notifications to check in whenever changes happened, but I kept missing them. I wanted something better. So I built an app to streamline my workflow. What I Built eyes-on-claude-code It's a cross-platform desktop application built with Tauri . I've only tested it on macOS (my daily environment), but the codebase is designed to support Linux as well. My Environment & Workflow This app is primarily designed to optimize my own workflow, so the features reflect my environment and habits. I develop using Ghostty + tmux . My typical workflow looks like this: Draft ideas and design in Markdown Give instructions to Claude Code (using Plan mode for larger tasks) Review the diff of generated code, then provide additional instructions or continue Features Multi-Session Monitoring Dashboard The dashboard monitors Claude Code sessions by receiving events through hooks configured in the global settings.json . Since I keep this running during development, I designed it with a minimal, non-intrusive UI. Always-on-top mode (optional) ensures the window doesn't get buried under other apps—so you never miss a notification. Transparency settings let you configure opacity separately for active and inactive states. When inactive, you can make it nearly invisible so it doesn't get in the way. It's there in the top-right corner, barely visible. Status Display & Sound Notifications Sessions are displayed with one of four states: State Meaning Display Active Claude is working 🟢 WaitingPermission Waiting for permission approval 🔐 WaitingInput Waiting for user input (idle) ⏳ Completed Response complete ✅ Sound effects play on state changes (can be toggled off): Waiting (Permission/Input) : Alert tone (two low beeps) Completed : Completion chime (ascending two-note sound) I'm planning to add volume control and custom commands in the future—like using say to speak or playing music on completion 🎵 Git-Based Diff Viewer I usually review AI-generated changes using difit . I wanted to integrate that same flow into this app, so you can launch difit directly on changed files. Huge thanks to the difit team for building such a great tool! tmux Integration When developing, I use tmux panes and tabs to manage multiple windows. My typical setup is Claude Code on the left half, and server/commands on the right. When working across multiple projects or branches via git worktree, it's frustrating to hunt for which tmux tab has Claude Code running. So I added a tmux mirror view that lets you quickly check results and give simple instructions without switching tabs. How It Works The app uses Claude Code hooks to determine session status based on which hooks fire. Event Flow I didn't want to introduce complexity with an intermediate server for inter-process communication. So I went with a simple approach: hooks write to log files, and the app watches those files. Hooks write logs to a temporary directory ( .local/eocc/logs ), which the app monitors. Since Claude Code runs in a terminal, hooks can access terminal environment paths. This lets me grab tmux and npx paths from within hooks and pass them to the app. Mapping Hooks to Status Claude Code provides these hook events: https://code.claude.com/docs/hooks-guide Here's how I map them to session states: Event Usage Session State session_start (startup/resume) Start a session Active session_end End a session Remove session notification (permission_prompt) Waiting for approval WaitingPermission notification (idle_prompt) Waiting for input WaitingInput stop Response completed Completed post_tool_use After tool execution Active user_prompt_submit Prompt submitted Active Conclusion I've only been using Claude Code as my primary tool for about two months, and I expect my workflow will keep evolving. Thanks to AI, I can quickly build and adapt tools like this—which is exactly what makes this era so exciting. If your workflow is similar to mine, give it a try! I'd love to hear your feedback.

Most of the time, you can write inline HTML directly into your posts. We support native Liquid tags and created some fun custom ones, too! Trying embedding a Tweet or GitHub issue in your post, using the complete URL: {% embed https://... %} . Links to unpublished posts are shareable for feedback/review. When you're ready to publish, set the published variable to true or click publish depending on the editor version, you're using Links to unpublished posts (drafts or scheduled posts) are shareable for feedback/review. These posts have a notice which reads "This URL is public but secret, so share at your own discretion." They are not visible in feeds or on your profile until published. description area in Twitter cards and open graph cards We have two editor versions . If you'd prefer to edit title and tags etc. as separate fields, switch to the "rich + markdown" option in Settings → Customization . Otherwise, continue: Front Matter Custom variables set for each post, located between the triple-dashed lines in your editor Here is a list of possibilities: title: the title of your article published: boolean that determines whether or not your article is published. tags: max of four tags, needs to be comma-separated canonical_url: link for the canonical version of the content cover_image: cover image for post, accepts a URL. The best size is 1000 x 420. series: post series name. ✍ Markdown Basics Below are some examples of commonly used markdown syntax. If you want to dive deeper, check out this cheat sheet. Bold & Italic Italics : *asterisks* or _underscores_ Bold : **double asterisks** or __double underscores__ Links I'm an inline link : [I'm an inline link](put-link-here) Anchored links (For things like a Table of Contents) ## Table Of Contents * [Chapter 1](#chapter-1) * [Chapter 2](#chapter-2) ### Chapter 1 <a name="chapter-1"></a> Inline Images When adding GIFs to posts and comments, please note that there is a limit of 200 megapixels per frame/page.  You can even add a caption using the HTML figcaption tag! Headings Add a heading to your post with this syntax: # One '#' for a h1 heading ## Two '#'s for a h2 heading ... ###### Six '#'s for a h6 heading Author Notes/Comments Add some hidden notes/comments to your article with this syntax: <!-- This won't show up in the content! --> Accessibility People access online content in all kinds of different ways, and there are a few things you can do to make your posts more easily understood by a broad range of users. You can find out more about web accessibility at W3C's Introduction to Web Accessibility , but there are two main ways you can make your posts more accessible: providing alternative descriptions of any images you use, and adding appropriate headings. Providing alternative descriptions for images Some users might not be able to see or easily process images that you use in your posts. Providing an alternative description for an image helps make sure that everyone can understand your post, whether they can see the image or not. When you upload an image in the editor, you will see the following text to copy and paste into your post:  Replace the "Image description" in square brackets with a description of your image - for example:  By doing this, if someone reads your post using an assistive device like a screen reader (which turns written content into spoken audio) they will hear the description you entered. Providing headings Headings provide an outline of your post to readers, including people who can't see the screen well. Many assistive technologies (like screen readers) allow users to skip directly to a particular heading, helping them find and understand the content of your post with ease. Headings can be added in levels 1 - 6 . Avoid using a level one heading (i.e., '# Heading text'). When you create a post, your post title automatically becomes a level one heading and serves a special role on the page, much like the headline of a newspaper article. Similar to how a newspaper article only has one headline, it can be confusing if multiple level one headings exist on a page. In your post content, start with level two headings for each section (e.g. '## Section heading text'), and increase the heading level by one when you'd like to add a sub-section, for example: ## Fun facts about sloths ### Speed Sloths move at a maximum speed of 0.27 km/h! 🌊 Liquid Tags We support native Liquid tags in our editor, but have created our own custom tags as well. A list of supported custom embeds appears below. To create a custom embed, use the complete URL: {% embed https://... %} Supported URL Embeds DEV Community Comment DEV Community Link DEV Community Link DEV Community Listing DEV Community Organization DEV Community Podcast Episode DEV Community Tag DEV Community User Profile asciinema CodePen CodeSandbox DotNetFiddle GitHub Gist, Issue or Repository Glitch Instagram JSFiddle JSitor Loom Kotlin Medium Next Tech Reddit Replit Slideshare Speaker Deck SoundCloud Spotify StackBlitz Stackery Stack Exchange or Stack Overflow Twitch Twitter Twitter timeline Wikipedia Vimeo YouTube Supported Non-URL Embeds Call To Action (CTA) {% cta link %} description {% endcta %} Provide a link that a user will be redirected to. The description will contain the label/description for the call to action. Details You can embed a details HTML element by using details, spoiler, or collapsible. The summary will be what the dropdown title displays. The content will be the text hidden behind the dropdown. This is great for when you want to hide text (i.e. answers to questions) behind a user action/intent (i.e. a click). {% details summary %} content {% enddetails %} {% spoiler summary %} content {% endspoiler %} {% collapsible summary %} content {% endcollapsible %} KaTex Place your mathematical expression within a KaTeX liquid block, as follows: {% katex %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} To render KaTeX inline add the "inline" option: {% katex inline %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} RunKit Put executable code within a runkit liquid block, as follows: {% runkit // hidden setup JavaScript code goes in this preamble area const hiddenVar = 42 %} // visible, reader-editable JavaScript code goes here console.log(hiddenVar) {% endrunkit %} Parsing Liquid Tags as a Code Example To parse Liquid tags as code, simply wrap it with a single backtick or triple backticks. `{% mytag %}{{ site.SOMETHING }}{% endmytag %}` One specific edge case is with using the raw tag. To properly escape it, use this format: `{% raw %}{{site.SOMETHING }} {% ``endraw`` %}` Common Gotchas Lists are written just like any other Markdown editor. If you're adding an image in between numbered list, though, be sure to tab the image, otherwise it'll restart the number of the list.

Most of the time, you can write inline HTML directly into your posts. We support native Liquid tags and created some fun custom ones, too! Trying embedding a Tweet or GitHub issue in your post, using the complete URL: {% embed https://... %} . Links to unpublished posts are shareable for feedback/review. When you're ready to publish, set the published variable to true or click publish depending on the editor version, you're using Links to unpublished posts (drafts or scheduled posts) are shareable for feedback/review. These posts have a notice which reads "This URL is public but secret, so share at your own discretion." They are not visible in feeds or on your profile until published. description area in Twitter cards and open graph cards We have two editor versions . If you'd prefer to edit title and tags etc. as separate fields, switch to the "rich + markdown" option in Settings → Customization . Otherwise, continue: Front Matter Custom variables set for each post, located between the triple-dashed lines in your editor Here is a list of possibilities: title: the title of your article published: boolean that determines whether or not your article is published. tags: max of four tags, needs to be comma-separated canonical_url: link for the canonical version of the content cover_image: cover image for post, accepts a URL. The best size is 1000 x 420. series: post series name. ✍ Markdown Basics Below are some examples of commonly used markdown syntax. If you want to dive deeper, check out this cheat sheet. Bold & Italic Italics : *asterisks* or _underscores_ Bold : **double asterisks** or __double underscores__ Links I'm an inline link : [I'm an inline link](put-link-here) Anchored links (For things like a Table of Contents) ## Table Of Contents * [Chapter 1](#chapter-1) * [Chapter 2](#chapter-2) ### Chapter 1 <a name="chapter-1"></a> Inline Images When adding GIFs to posts and comments, please note that there is a limit of 200 megapixels per frame/page.  You can even add a caption using the HTML figcaption tag! Headings Add a heading to your post with this syntax: # One '#' for a h1 heading ## Two '#'s for a h2 heading ... ###### Six '#'s for a h6 heading Author Notes/Comments Add some hidden notes/comments to your article with this syntax: <!-- This won't show up in the content! --> Accessibility People access online content in all kinds of different ways, and there are a few things you can do to make your posts more easily understood by a broad range of users. You can find out more about web accessibility at W3C's Introduction to Web Accessibility , but there are two main ways you can make your posts more accessible: providing alternative descriptions of any images you use, and adding appropriate headings. Providing alternative descriptions for images Some users might not be able to see or easily process images that you use in your posts. Providing an alternative description for an image helps make sure that everyone can understand your post, whether they can see the image or not. When you upload an image in the editor, you will see the following text to copy and paste into your post:  Replace the "Image description" in square brackets with a description of your image - for example:  By doing this, if someone reads your post using an assistive device like a screen reader (which turns written content into spoken audio) they will hear the description you entered. Providing headings Headings provide an outline of your post to readers, including people who can't see the screen well. Many assistive technologies (like screen readers) allow users to skip directly to a particular heading, helping them find and understand the content of your post with ease. Headings can be added in levels 1 - 6 . Avoid using a level one heading (i.e., '# Heading text'). When you create a post, your post title automatically becomes a level one heading and serves a special role on the page, much like the headline of a newspaper article. Similar to how a newspaper article only has one headline, it can be confusing if multiple level one headings exist on a page.

It is through these differences that our community experiences great successes and continued growth. When you're working with members of the community, this Code of Conduct will help steer your interactions and keep Python a positive, successful, and growing community. Our Community Members of the Python community are open, considerate, and respectful . Behaviours that reinforce these values contribute to a positive environment, and include: Being open. Members of the community are open to collaboration, whether it's on PEPs, patches, problems, or otherwise. Focusing on what is best for the community. We're respectful of the processes set forth in the community, and we work within them. Acknowledging time and effort. We're respectful of the volunteer efforts that permeate the Python community. We're thoughtful when addressing the efforts of others, keeping in mind that often times the labor was completed simply for the good of the community. Being respectful of differing viewpoints and experiences. We're receptive to constructive comments and criticism, as the experiences and skill sets of other members contribute to the whole of our efforts. Showing empathy towards other community members. We're attentive in our communications, whether in person or online, and we're tactful when approaching differing views. Being considerate. Members of the community are considerate of their peers -- other Python users. Being respectful. We're respectful of others, their positions, their skills, their commitments, and their efforts. Gracefully accepting constructive criticism. When we disagree, we are courteous in raising our issues. Using welcoming and inclusive language. We're accepting of all who wish to take part in our activities, fostering an environment where anyone can participate and everyone can make a difference. Our Standards Every member of our community has the right to have their identity respected. The Python community is dedicated to providing a positive experience for everyone, regardless of age, gender identity and expression, sexual orientation, disability, physical appearance, body size, ethnicity, nationality, race, or religion (or lack thereof), education, or socio-economic status. Inappropriate Behavior Examples of unacceptable behavior by participants include: Harassment of any participants in any form Deliberate intimidation, stalking, or following Logging or taking screenshots of online activity for harassment purposes Publishing others' private information, such as a physical or electronic address, without explicit permission Violent threats or language directed against another person Incitement of violence or harassment towards any individual, including encouraging a person to commit suicide or to engage in self-harm Creating additional online accounts in order to harass another person or circumvent a ban Sexual language and imagery in online communities or in any conference venue, including talks Insults, put downs, or jokes that are based upon stereotypes, that are exclusionary, or that hold others up for ridicule Excessive swearing Unwelcome sexual attention or advances Unwelcome physical contact, including simulated physical contact (eg, textual descriptions like "hug" or "backrub") without consent or after a request to stop Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others Sustained disruption of online community discussions, in-person presentations, or other in-person events Continued one-on-one communication after requests to cease Other conduct that is inappropriate for a professional audience including people of many different backgrounds Community members asked to stop any inappropriate behavior are expected to comply immediately. Weapons Policy No weapons are allowed at Python Software Foundation events. Weapons include but are not limited to explosives (including fireworks), guns, and large knives such as those used for hunting or display, as well as any other item used for the purpose of causing injury or harm to others. Anyone seen in possession of one of these items will be asked to leave immediately, and will only be allowed to return without the weapon. Consequences If a participant engages in behavior that violates this code of conduct, the Python community Code of Conduct team may take any action they deem appropriate, including warning the offender or expulsion from the community and community events with no refund of event tickets. The full list of consequences for inappropriate behavior is listed in the Enforcement Procedures . Thank you for helping make this a welcoming, friendly community for everyone. Scope PSF Events This Code of Conduct applies to the following people at events hosted by the Python Software Foundation, and events hosted by projects under the PSF's fiscal sponsorship : staff Python Software Foundation board members speakers panelists tutorial or workshop leaders poster presenters people invited to meetings or summits exhibitors organizers volunteers all attendees The Code of Conduct applies in official venue event spaces, including: exhibit hall or vendor tabling area panel and presentation rooms hackathon or sprint rooms tutorial or workshop rooms poster session rooms summit or meeting rooms staff areas con suite meal areas party suites walkways, hallways, elevators, and stairs that connect any of the above spaces The Code of Conduct applies to interactions with official event accounts on social media spaces and phone applications, including: comments made on official conference phone apps comments made on event video hosting services comments made on the official event hashtag or panel hashtags Event organizers will enforce this code throughout the event. Each event is required to provide a Code of Conduct committee that receives, evaluates, and acts on incident reports. Each event is required to provide contact information for the committee to attendees.

Report Abuse Anmol Baranwal for Composio Posted on Jan 12 • Originally published at composio.dev How Rube MCP Solves Context Overload When Using Hundreds of MCP Servers # ai # mcp # programming # productivity Over the past year, I have used ChatGPT for everything from drafting emails to debugging code and it’s wildly useful. But I kept finding myself doing the tedious glue work. That repeated work never felt like a good use of time so I started looking for something that closes the loop. I recently found Rube MCP , a Model Context Protocol (MCP) server that connects ChatGPT and other AI assistants to 500+ apps (such as Gmail, Slack, Notion, GitHub, Supabase, Stripe, Reddit). For the last few weeks, I have been testing it out & trying to understand how it think and works. This post covers everything I picked up. What is covered? What is MCP? (Brief Intro) What is Rube MCP & how does it help? How Rube Thinks: Meta Tools, Planning & Execution How does it work under the hood? Connecting Rube to ChatGPT Three practical examples with demos. What’s Still Missing. We will be covering a lot so let's get started. What is MCP? MCP (Model Context Protocol) is Anthropic's attempt at standardizing how applications provide context and tools to LLMs. Think of it like HTTP for AI models - a standardized protocol for AI models to “plug in” to data sources and tools. Instead of writing custom integrations (GitHub, Slack, databases, file systems), MCP lets a host dynamically discover available tools ( tools/list ), invoke them ( tools/call ) and get back structured results. This mimics function-calling APIs but works across platforms and services. If you are interested in reading more, here are a couple of good reads: The guide to MCP I never had What is the Model Context Protocol (MCP)? by the Builder.io team credit: ByteByteGo Now that you understand MCP, here’s where Rube MCP comes in. What is Rube MCP & why it matters? MCP provides a standardized “tool directory” so AI can discover and call services using JSON-RPC, without each model having to memorize all the API details. Rube is a universal MCP server built by Composio. It acts as a bridge between AI assistants and a large ecosystem of tools. It implements the MCP standard for you, serving as middleware: the AI assistants talk to Rube via MCP and Rube talks to all your apps via pre-built connectors. You get a single MCP endpoint (like https://rube.app/mcp ) to plug into your AI client, while Composio manages everything (adapters, authentication, versioning and connector updates) behind the scenes. You can learn more at rube.app . Once you sign up on the website, you can check recent chats, connect/remove apps at any time and find/enable any supported app in the marketplace. You can integrate Rube with: ChatGPT (Developer Mode or Custom GPT) Agent Builder (OpenAI) Claude Desktop Claude Code Cursor/VS Code Any generic MCP-compatible client via HTTP / SSE transport (you point it to https://rube.app/mcp ) You can also do it for systems like N8N, custom apps or automation platforms using Auth Headers (signed tokens or API keys) with HTTP requests. We will be covering how to set it up later but you can find the detailed instructions on the website. Where it helps Sure, AI Assistants can write beautiful code, explain complex concepts and even help you debug, but when it comes to actually doing anything in your workflow, they are not really useful. Rube solves this major problem. Instead of the model guessing which API to use or dealing with OAuth, Rube translates your plain-English request into the correct API calls. For example, Rube can parse: “Send a welcome email to the latest sign-up” into Gmail API calls “Create a Linear ticket titled ‘Bug in checkout flow” into the right Linear endpoint Because Rube standardizes these integrations, you don’t have to update prompts every time an API changes. In the dashboard, you will also find a library of recipes. They are basically a list of shortcuts that turn your complex tasks into instant automations. You can view the workflow in detail, run directly, even fork it to modify based on your needs. If you are wondering how automation would actually work, you can try asking Rube itself. In my case, it would be as following. Security & Privacy Rube is designed with privacy-first principles. Credentials flow directly between you and the app (via OAuth 2.1). Rube (Composio) never sees your raw passwords. All tokens are end-to-end encrypted. You choose which apps to connect and which permissions each has. You can remove an app at any time from the Rube dashboard. For teams, Rube supports shared connections : which means one person can connect Gmail for the team and everyone’s ChatGPT can use it (without re-authenticating). How Rube Thinks: Meta Tools, Planning & Execution Rube thinks through your requests using built-in meta tools. The smart layer (planning, workbench) handle the hard parts automatically. These meta tools run on top of Rube's MCP protocol. ✅ RUBE_SEARCH_TOOLS is a meta tool that inspects your task description and returns the best tools, toolkits and connection status to use for that task. For example, to check Medium emails in Gmail and write summaries into a Notion page, you can call: RUBE_SEARCH_TOOLS( { session: { id: "vast" }, use_case: "Fetch unread Gmail messages from last 30 days that mention Medium Daily Digest or are from [noreply@medium.com](mailto:noreply@medium.com), then add rows to a Notion database page titled Medium Blogs with columns for Title, Summary and Priority" , known_fields: "sender:noreply@medium.com, query_keyword:Medium Daily Digest, days:30, notion_page_title:Medium Blogs" } ) Enter fullscreen mode Exit fullscreen mode A successful response for this task looks like (trimmed to the most important fields): { "data" : { "main_tool_slugs" : [ "NOTION_SEARCH_NOTION_PAGE" , "NOTION_CREATE_NOTION_PAGE" , "NOTION_ADD_MULTIPLE_PAGE_CONTENT" ], "related_tool_slugs" : [ "NOTION_FETCH_DATA" , "NOTION_GET_ABOUT_ME" , "NOTION_UPDATE_PAGE" , "NOTION_APPEND_BLOCK_CHILDREN" , "NOTION_QUERY_DATABASE" ], "toolkits" : [ { "toolkit" : "NOTION" , "description" : "NOTION toolkit" } ], "connection_statuses" : [ { "toolkit" : "notion" , "active_connection" : true , "message" : "Connection is active and ready to use" } ], "memory" : { "all" : [ "Medium Blogs page has ID 287a763a-b038-802e-b22f-f8d853f591a0" , "User is fetching unread emails from last 30 days from noreply@medium.com or with subject containing Medium Daily Digest" ] }, "query_type" : "search" , "reasoning" : "NOTION is required to create the new page titled \" Medium Blogs \" and to add formatted text blocks. GMAIL is needed to retrieve the email titles, summaries, and priority information that will populate those text blocks." , "session" : { "id" : "vast" }, "time_info" : { "current_time" : "2025-10-10T16:15:36.452Z" } }, "successful" : true } Enter fullscreen mode Exit fullscreen mode ✅ RUBE_CREATE_PLAN is a planning meta tool that takes your task description and returns a structured, multi‑step workflow: tools to call, ordering, parallelization, edge‑case handling and user‑confirmation rules. For the same Gmail→Notion workflow, you can call: RUBE_CREATE_PLAN( { session: { id: "vast" }, use_case: "Fetch unread Gmail messages from last 30 days that mention Medium Daily Digest or are from noreply@medium.com, summarize them with an LLM, and insert one row per email into the Medium Blogs Notion database with Title, Summary and Priority columns." , difficulty: "medium" , known_fields: "sender:noreply@medium.com, query_keyword:Medium Daily Digest, days:30, notion_database:Medium Blogs" } ) Enter fullscreen mode Exit fullscreen mode A successful response for this task looks like (trimmed to the most important fields): { "data" : { "workflow_instructions" : { "plan" : { "workflow_steps" : [ { "step_id" : "S1" , "tool" : "GMAIL_FETCH_EMAILS" , "intent" : "Fetch IDs of unread Gmail messages from the last 30 days that are either from noreply@medium.com or mention 'Medium Daily Digest' in subject/body." , "parallelizable" : true , "output" : "List of message IDs with minimal metadata." , "notes" : "Paginate with nextPageToken until all results are fetched." }, { "step_id" : "S2" , "tool" : "GMAIL_FETCH_MESSAGE_BY_MESSAGE_ID" , "intent" : "..." , "parallelizable" : true , "output" : "..." , "notes" : "..." }, { "step_id" : "S3" , "tool" : "COMPOSIO_REMOTE_WORKBENCH" , "intent" : "..." , "parallelizable" : true , "output" : "..." }, { "step_id" : "S4" , "tool" : "NOTION_SEARCH_NOTION_PAGE" , "intent" : "..." , "parallelizable" : false , "output" : "..." }, { "step_id" : "S5" , "tool" : "NOTION_FETCH_DATABASE" , "intent" : "..." , "parallelizable" : false , "output" : "..." }, { "step_id" : "S6" , "tool" : "USER_CONFIRMATION" , "intent" : "..." , "parallelizable" : false , "output" : "..." }, { "step_id" : "S7" , "tool" : "COMPOSIO_MULTI_EXECUTE_TOOL" , "intent" : "..." , "parallelizable" : true , "output" : "..." } ], "complexity_assessment" : { "overall_classification" : "Complex multi-step workflow" , "data_volume" : "..." , "time_sensitivity" : "..." }, "decision_matrix" : { "tool_order_priority" : [ "GMAIL_FETCH_EMAILS (S1)" , "GMAIL_FETCH_MESSAGE_BY_MESSAGE_ID (S2)" , "COMPOSIO_REMOTE_WORKBENCH (S3)" , "NOTION_SEARCH_NOTION_PAGE (S4)" , "NOTION_FETCH_DATABASE (S5)" , "USER_CONFIRMATION (S6)" , "COMPOSIO_MULTI_EXECUTE_TOOL (S7)" ], "edge_case_strategies" : [ "If S1 yields no IDs, skip S2–S7 and return an empty result." , "If the Notion database cannot be found, prompt the user for an alternate target." , "If the user denies confirmation in S6, stop before any Notion inserts." ] }, "failure_handling" : { "gmail_fetch_failure" : [ "..." ], "notion_discovery_failure" : [ "..." ], "insertion_failure" : [ "..." ] }, "user_confirmation" : { "requirement" : true , "prompt_template" : "..." , "post_confirmation_action" : "..." }, "output_format" : { "final_delivery" : "..." , "links_and_references" : "..." } }, "critical_instructions" : "Use pagination correctly, respect time-awareness, and always get explicit user approval before irreversible actions." , "time_info" : { "current_date" : "..." , "current_time_epoch_in_seconds" : 1760112500 } }, "session" : { "id" : "vast" , "instructions" : "..." } }, "successful" : true } Enter fullscreen mode Exit fullscreen mode If you are using Rube through any other assistant like ChatGPT, you will still be able to inspect all the calls. ✅ RUBE_MULTI_EXECUTE_TOOL is a high‑level orchestrator that runs multiple tools in parallel, using the plan from RUBE_CREATE_PLAN to batch calls like Gmail fetches or Notion inserts into a single step. RUBE_MULTI_EXECUTE_TOOL( { session_id: "vast" , tools: [ /* up to 20 prepared tool calls , e.g. NOTION_INSERT_ROW_DATABASE for each email */ ], sync_response_to_workbench: true } ) Enter fullscreen mode Exit fullscreen mode Here tools is the list of concrete tool invocations generated from the plan and sync_response_to_workbench: true streams the results into the Remote Workbench so the agent can post‑process outputs or handle failures across the whole batch. If you have been following the examples, the final “execution engine” in S7 of the last plan used this step. After the emails are summarized and the user confirms, COMPOSIO_MULTI_EXECUTE_TOOL fires many NOTION_INSERT_ROW_DATABASE (and similar) calls concurrently so each Medium email becomes a Notion row without the agent manually looping over tools. { "step_id" : "S7" , "tool" : "COMPOSIO_MULTI_EXECUTE_TOOL" , "intent" : "After user confirmation, insert rows into Notion for all summarized emails by leveraging the discovered database schema, in parallel batches." , "parallelizable" : true , "output" : "Created Notion rows and returned row identifiers/links." , "notes" : "Use NOTION_INSERT_ROW_DATABASE per email. If there are many emails, batch in parallel calls (up to tool limits). Reference: Notion insert API usage [Notion API — Create a page in a database](https://developers.notion.com/docs/working-with-dilters#create-a-page-in-a-database)." } Enter fullscreen mode Exit fullscreen mode ✅ RUBE_REMOTE_WORKBENCH is a cloud sandbox for running arbitrary Python between tool calls, perfect for parsing raw API responses, batching LLM calls and preparing data for Notion or other apps (such as parsing email HTML → format for Notion). For this workflow, it was first called like this: RUBE_REMOTE_WORKBENCH( { session_id: "vast" , current_step: "PROCESSING_EMAILS" , next_step: "GENERATING_SUMMARIES" , file_path: "/home/user/.composio/output/multi_execute/multi_execute_response_1760112513002_akfm55.json" , code_to_execute: "import json \n # Load the Gmail response file \n data = json.load(open('/home/user/.composio/output/multi_execute/multi_execute_response_1760112513002_akfm55.json')) \n # Extract Medium emails, print counts and a few subjects for debugging..." } ) Enter fullscreen mode Exit fullscreen mode Inside the sandbox, the script loads the multi‑execute Gmail response JSON from disk, filters out the Medium emails and prints diagnostics to stdout such as “Found 30 Medium emails”, “Extracted 30 emails”, plus the first three subjects. Basically to confirm that upstream Gmail calls worked and giving the agent something human‑readable to reason about. The corresponding (trimmed) result looks like: { "data" : { "stdout" : "Found 30 Medium emails \n Extracted 30 emails \n\n First 3 email subjects: \n 1. ... \n 2. ... \n 3. ... \n " , "stderr" : "" , "results_file_path" : null , "session" : { "id" : "vast" } }, "successful" : true } Enter fullscreen mode Exit fullscreen mode The agent then reuses the same workbench in later steps (with different current_step / next_step and code_to_execute ) to batch LLM calls and write cleaned summaries to a file that the Notion tools consume. But the calling pattern are always the same. The next section goes deep on how it works under the hood, which is the MCP transport layer (JSON-RPC, connectors). How Rube MCP Works (Under the Hood) At a high level, Rube is an MCP server that implements the MCP spec on the server side. Your AI client communicates with Rube over HTTP/JSON-RPC. Whenever you ask the AI to “send a message” or “create a ticket,” here’s what happens behind the scenes: ✅ 1. AI Client → Rube MCP Server It first requests a tool catalog, a machine-readable list of everything Rube can do. When you trigger a command, the client sends a tool call (a JSON-RPC request) to Rube with parameters like: { "method" : "send_email" , "params" : { "to" : "user@example.com" } } Enter fullscreen mode Exit fullscreen mode Rube returns structured JSON responses. The ChatGPT and other AI interfaces have built-in support for this MCP format, so they handle the conversation around it. ✅ 2. Rube MCP Server → Composio Platform Rube runs on Composio’s infrastructure, which manages a massive library of pre-built tools (connectors). When Rube receives a tool call from your AI client (say send_slack_message ), it looks up the right connector and hands off the request to Composio. It then routes it to the appropriate adapter. Think of Rube as a universal translator: it takes structured MCP requests from your AI and turns them into actionable API calls using Composio’s connector ecosystem. ✅ 3. Connector / Adapter Layer Each app has its own connector or adapter that knows how to talk to that app’s API. The adapter knows how to handle: API routes and parameters Pagination, rate limits, and retries Response formatting and error handling return structured JSON back to Rube This design makes Rube easily extensible: when Composio adds a new connector, it becomes instantly available in Rube without any code changes. ✅ 4. OAuth Flow When you first connect an app, Rube triggers an OAuth flow. For example, saying “send an email” will prompt you to sign in to Gmail and grant access. Composio then encrypts and stores your tokens securely, which you can always view, revoke or reauthorize in the dashboard. ✅ 5. Response & Chaining Once the connector completes the API call, it returns a structured JSON response back to Rube, which then sends it to your AI client. The AI can use that data in the next step like summarizing results, creating follow-up actions or chaining multiple tools together in one flow. A simple example can be: Hey Rube -- check our shared Sales inbox for unread messages from the last 48h. Summarize each in 2 bullets, draft polite replies for high-priority pricing requests and post a summary to #sales-updates on Slack . So that’s the magic under the hood. Let’s set it up with ChatGPT and see it in action. Connecting Rube to ChatGPT There are a few ways to start using Rube: the simplest is to chat directly from the dashboard. But since we will be using ChatGPT for the demo later, let’s start there. You can use Rube inside ChatGPT in two ways: 1) Custom Rube Custom GPT : Just open the Custom GPT, connect your apps and start running Rube-powered actions directly in chat. No setup needed. 2) Developer Mode : for advanced users who want to manually add Rube as an MCP server. You will need a ChatGPT Pro plan for this but it only takes a few minutes to set up. Let’s walk through it step-by-step: Start by opening ChatGPT Settings and navigating to Apps & Connectors, then click on Advanced Settings. Next, enable Developer Mode to access advanced connector features. Once enabled, copy the MCP URL ( https://rube.app/mcp ). You will now see a Create option on the top-right under Connectors. Click Create, enter the details, including the MCP URL you copied and save. You will have to sign up for Rube to complete the OAuth flow. After this, Rube will be fully connected and ready to use inside ChatGPT. I will also show how you can plug Rube into other assistants like Claude and Cursor in case you use those too. Rube with Cursor You can also connect Rube with Cursor using this link. It will take you straight to the settings, with the MCP URL already filled in so you can get started right away. Rube with Claude Code (CLI) Start by running the following command in your terminal: claude mcp add --transport http rube -s user "https://rube.app/mcp" Enter fullscreen mode Exit fullscreen mode This registers Rube as an MCP server in Claude Code. Next, open Claude Code and run the /mcp command to list available MCP servers. You should see Rube in the list. Claude Code will then prompt you to authenticate. A browser window will open where you can complete the OAuth login. Once authentication is finished, you can use Rube inside Claude Code. Rube with Claude Desktop If you are on the Pro plan, you can simply use the Add Custom Connector option in Claude Desktop and paste the MCP URL. For free plan users, you can set it up via the terminal by running: npx @composio/mcp@latest setup "https://rube.app/mcp" "rube" --client claude Enter fullscreen mode Exit fullscreen mode This will register Rube as an MCP server and you will be ready to start using it with Claude Desktop. If you want to connect to any other platforms that need an Authorization header, you can generate a signed token from the official website. Practical examples Seeing Rube in action is always better than just reading about it. Here, we will go through five real-world workflows. The first one will show the full flow, so you can see how Rube saves time and links multiple apps together. Before you start, make sure your apps are enabled in the marketplace from the dashboard. You can easily disconnect and modify scopes depending on your use case. ✅ 1. Gmail to Notion Workflow Let’s start with a simple but incredibly useful example: turning important emails into Notion tasks automatically. Every day, Medium sends a “Daily Digest” email (usually from noreply@medium.com ) full of trending stories and recommendations. Rube can automatically fetch the unread Daily Digest emails, pick the most relevant stories and organize them neatly in Notion so you get a clean reading list ready to go. Here is the prompt: Hey Rube -- check my Gmail inbox for unread messages from the last 30 days that mention “Medium Daily Digest” or are from noreply@medium.com. Extract all story titles and links. Summarize each story in 2 lines, assign a priority (High, Medium, Low) based on potential impact, and add them as new rows in my Notion page titled “Medium Blogs” with columns: Title, Summary, Priority and URL. Enter fullscreen mode Exit fullscreen mode As you can see, this isn’t a simple task. I intentionally made it quite challenging since it: has to find unread emails extract links from messy, HTML-heavy content generate meaningful summaries and decide what’s actually “relevant” or “high impact” The overall flow looks like this: Finding unread emails → Filtering only “Medium Daily Digest” ones → Parsing stories and summaries from HTML → Prioritizing by relevance or impact → Creating a structured format in Notion Here are the snapshots of the flow. Rube automatically calls the right tools and you can see everything that happens before approving the actions. You will also see the full breakdown of tool calls and step-by-step progress: And the best part: it solved everything automatically and completed the task cleanly. Here is the output notion page after all the entries were added. The links are accurate and clickable. I tried this through multiple ways (ChatGPT with Developer mode, Rube Custom ChatGPT, Rube dashboard Chat) and they all worked equally well. Here are a couple of snapshots from the dashboard chat: ✅ 2. GitHub → Slack (Developer Notifications) Let’s say your dev team wants to stay synced after every code change, without having to manually update each other. Here is the prompt: Hey Rube -- monitor my GitHub repo “acme/auth-service” for new pull requests or merges. When a PR is merged, post a message in Slack channel #dev-updates with the PR title, author, link. Enter fullscreen mode Exit fullscreen mode ✅ 3. Customer Support → GitHub Support teams often have to bridge the gap between customer tickets and dev work. Rube can quietly handle most of that coordination for you. Checks for new or updated Zendesk tickets Looks up each customer’s record in Salesforce Finds tickets that mention technical bugs Creates matching GitHub issues for the dev team Here is the prompt: Hey Rube -- check for new Zendesk tickets, pull the customer's order history from Salesforce and create github issues for any technical problems mentioned Enter fullscreen mode Exit fullscreen mode A simple message but it connects three different systems end-to-end. ✅ 4. Research → Notion (Idea Board) Let’s say you want to brainstorm ideas and need to see what people are talking about online. Rube can search Hacker News and Reddit, pick out the most relevant posts, summarize them quickly and add everything neatly to your Notion page. This way, your research board stays up-to-date without you having to comb through dozens of links yourself. Here is the prompt: Hey Rube -- search Hacker News and Reddit for "MCP server" mentions in the last 14 days Extract the top 10 posts, summarize each in 3 bullet points and add them to my Notion page "MCP Research Board" with: Source, Title, Summary, Link. Enter fullscreen mode Exit fullscreen mode ✅ 5. Gmail → Draft Replies Let's say you have got a bunch of emails to respond to, but you don’t want to spend hours drafting them. Rube can check your inbox for recent “Sales” emails, summarize each one and draft polite replies for the high-priority threads. You can instruct to save them as drafts to review before sending. Here is the prompt: Hey Rube -- check my Gmail inbox for unread messages from the last 48 hours labeled "Sales" Summarize each email in 2 bullet points and for high-priority messages asking for pricing or proposals draft a polite reply and save it as a Gmail draft under the label "Rube-Drafts" Enter fullscreen mode Exit fullscreen mode Think about what this means for productivity. Tasks that once required switching between 5+ apps can now happen in a single conversation with Rube. What’s Still Missing While I was trying Rube, I realized there are some practical limitations and gaps to keep in mind: 1) While Rube can chain actions across apps, very complex sequences (like if this, do that; else do something else ) can still confuse the AI. You may need to break tasks into smaller steps, manually supervise or guide the assistant more explicitly. 2) Rube supports 500+ apps but not every niche tool is integrated yet. And not everyone will switch apps because they always have a preference. 3) Rube can’t execute tasks locally since it relies on cloud connectivity and Composio’s servers. 4) There is no 100% guarantee that AI will never misinterpret ambiguous instructions or generate unintended actions. So always review critical commands, especially when automating emails, payments or database updates. I personally don't feel there is any learning curve, since you can start using it with a single click. This is the closest I have seen to a real “AI that gets things done”. If you have ever wished ChatGPT could just take care of the boring stuff, Rube is as close as it gets right now. Have a great day! Until next time :) You can check my work at anmolbaranwal.com .

Report Abuse Victor de la Fouchardière Posted on Aug 16, 2020 🤝 Promise.allSettled() VS Promise.all() in JavaScript 🍭 # node # webdev # javascript # beginners Hello ! 🧑🌾 Promises are available since ES2015 to simplify the handling of asynchronous operations. Let's discover 2 Promises and their differences: Promise.allSettled(iterable) Promise.all(iterable) Both of them take an iterable and return an array containing the fulfilled Promises. ❓ So, what is the difference between them ? Promise.all() 🧠 The Promise. all() method takes an iterable of promises as an input, and returns a single Promise that resolves to an array of the results of the input promises. All resolved As you can see, we are passing an array to Promise.all. And when all three promises get resolved, Promise.all resolves and the output is consoled. Now, let's see if one promise is not resolved , and so, if this one is reject. What was the output ? 🛑 1 failed Promise.all is rejected if at least one of the elements are rejected . For example, we pass 2 promises that resolve and one promise that rejects immediately, then Promise.all will reject immediately. Promise.allSettled() 🦷 Since ES2020 you can use Promise.allSettled . It returns a promise that always resolves after all of the given promises have either fulfilled or rejected, with an array of objects that each describes the outcome of each promise. For each outcome object, a status string is present : fulfilled ✅ rejected ❌ The value (or reason) reflects what value each promise was fulfilled (or rejected) with. Have a close look at following properties ( status , value , reason ) of resulting array. Differences 👬 Promise.all will reject as soon as one of the Promises in the array rejects. Promise.allSettled will never reject, it will resolve once all Promises in the array have either rejected or resolved. Supported Browsers 🚸 The browsers supported by JavaScript Promise.allSettled() and Promise.all() methods are listed below: Google Chrome Microsoft Edge Mozilla Firefox Apple Safari Opera Cheers 🍻 🍻 🍻 If you enjoyed this article you can follow me on Twitter or here on dev.to where I regularly post bite size tips relating to HTML, CSS and JavaScript. 📦 GitHub Profile: The RIGHT Way to Show your latest DEV articles + BONUS 🎁 Victor de la Fouchardière ・ Aug 5 '20 #github #markdown #showdev #productivity 🍦 Cancel Properly HTTP Requests in React Hooks and avoid Memory Leaks 🚨 Victor de la Fouchardière ・ Jul 29 '20 #react #javascript #tutorial #showdev Top comments (14) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Michael Levan Posted on Jun 15, 2022 • Edited on Aug 6, 2025 Kubernetes Ingress vs Service Mesh # kubernetes # devops # cloud # git Networking in Kubernetes is no easy task. Whether you’re on the application side or the operations side, you need to think about networking. Whether it’s connectivity between clusters, control planes, and worker nodes, or connectivity between Kubernetes Services and Pods, it all becomes a task that needs a large amount of focus and effort. In this blog post, you’ll learn about what a service mesh is, what ingress is, and why you need both. What’s A Service Mesh When you deploy applications inside of Kubernetes, there are two primary ways that the apps are talking to each other: Service-to-Service communication Pod-to-Pod communication Pod-to-Pod communication isn’t exactly recommended because Pods are ephemeral, which means they aren’t permanent. They are designed to go down at any time and only if they’re part of a StatefulSet would they keep any type of unique identifier. However, Pods still need to be able to communicate with each other because microservices need to talk. Backends need to talk to frontends, middleware needs to talk to backends and frontends, etc… The next primary communication is Services. Services are the preferred method because a Service isn’t ephemeral and only gets deleted if specified by an engineer. Pods are able to connect to Services with Selectors (sometimes called Tags), so if a Pod goes down but the Selector in the Kubernetes Manifest that deployed the Pod doesn’t change, the new Pod will be connected to the Service. In short, a Service sits in front of Pods almost like a load balancer would (not to be confused with the LoadBalancer service type). Here’s the problem: all of this traffic is unencrypted by default. Pod-to-Pod communication, or as some people like to call it, East-West Traffic, and Service-to-Service is completely unencrypted. That means if for any reason an environment is compromised or you have some segregation concerns, there’s nothing out of the box that you can do. A Service Mesh handles a lot of that for you. A Service Mesh: Encrypts traffic between Services Helps with network latency troubleshooting Securely connects Kubernetes Services Observability for tracing and alerting The key piece here, aside from the encryption between services (using mTLS) is the network observability and routing implementations. As a small example, the following routing rule forwards traffic to /rooms via a delegate VirtualService object/kind named roompage . apiVersion: networking.istio.io/v1 kind: VirtualService metadata: name: hotebooking spec: hosts: - "hotelbooking.com" gateways: - hbgateway http: - match: - uri: prefix: "/rooms" delegate: name: roompage namespace: rooms Enter fullscreen mode Exit fullscreen mode You have full control over the "what and how" in terms of routing. What’s Ingress Outside of the need for secure communication between microservices, you need a way to interact with frontend apps. The typical way is with a load balancer that’s connected to a Service. You can also use a NodePort, but in the cloud world, you’ll mostly see load balancers being used. Here’s the problem; cloud load balancers are expensive literally and figuratively. You have to pay money for each cloud load balancer that you have. Having a few applications may not be a big deal, but what about if you have 50 or 100? Not to mention that you have to manage all of those cloud load balancers. If a Kubernetes Service disconnects from the load balancer for whatever reason, it’s your job to go in and fix it. With Kubernetes Ingress Controllers, the management and cost nightmare is abstracted from you. An Ingress Controller allows you to have: One load balancer Multiple applications (Kubernetes Services) pointing to it You can create one load balancer and have every Kubernetes Service point to it that's within the specific web application from a routing perspective. Then, you can access each Kubernetes Service on a different path. For example, below is an Ingress Spec that points to a Kubernetes Service called nginxservice and outputs it on the path called /nginxappa apiVersion : networking . k8s . io / v1 kind : Ingress metadata : name : ingress - nginxservice - a spec : ingressClassName : nginx - servicea rules : - host : localhost http : paths : - path : / nginxappa pathType : Prefix backend : service : name : nginxservice port : number : 8080 Enter fullscreen mode Exit fullscreen mode Ingress Controllers are like an Nginx Reverse Proxy. Do You Need Both? My take on it is that you need both. Here’s why: They’re both doing two different jobs. I always like to use the hammer analogy. If I need to hammer a nail, I can use the handle to slam the nail in and eventually it’ll work, but why would I do that if I can use the proper end of the hammer? An Ingress Controller is used to: Make load balancing apps easier A Service Mesh is used to: Secure communication between apps Help out with Kubernetes networking Now, here’s the kicker; there are tools that do both. For example, Istio Ingress is an Ingress Controller, but also has the capability of secure gateways using mTLS. If you’re using one of those tools, great. Just make sure that it handles both communication and security for you in the way that you’re expecting. The recommendation still is to use the proper tool for the job. Both Service Mesh and Ingress are incredibly important, especially as your microservice environment grows.

Sort of like a "middle ground". Where-as the ingress controllers are more about handling frontend app traffic.

Most of the time, you can write inline HTML directly into your posts. We support native Liquid tags and created some fun custom ones, too! Trying embedding a Tweet or GitHub issue in your post, using the complete URL: {% embed https://... %} . Links to unpublished posts are shareable for feedback/review. When you're ready to publish, set the published variable to true or click publish depending on the editor version, you're using Links to unpublished posts (drafts or scheduled posts) are shareable for feedback/review. These posts have a notice which reads "This URL is public but secret, so share at your own discretion." They are not visible in feeds or on your profile until published. description area in Twitter cards and open graph cards We have two editor versions . If you'd prefer to edit title and tags etc. as separate fields, switch to the "rich + markdown" option in Settings → Customization . Otherwise, continue: Front Matter Custom variables set for each post, located between the triple-dashed lines in your editor Here is a list of possibilities: title: the title of your article published: boolean that determines whether or not your article is published. tags: max of four tags, needs to be comma-separated canonical_url: link for the canonical version of the content cover_image: cover image for post, accepts a URL. The best size is 1000 x 420. series: post series name. ✍ Markdown Basics Below are some examples of commonly used markdown syntax. If you want to dive deeper, check out this cheat sheet. Bold & Italic Italics : *asterisks* or _underscores_ Bold : **double asterisks** or __double underscores__ Links I'm an inline link : [I'm an inline link](put-link-here) Anchored links (For things like a Table of Contents) ## Table Of Contents * [Chapter 1](#chapter-1) * [Chapter 2](#chapter-2) ### Chapter 1 <a name="chapter-1"></a> Inline Images When adding GIFs to posts and comments, please note that there is a limit of 200 megapixels per frame/page.  You can even add a caption using the HTML figcaption tag! Headings Add a heading to your post with this syntax: # One '#' for a h1 heading ## Two '#'s for a h2 heading ... ###### Six '#'s for a h6 heading Author Notes/Comments Add some hidden notes/comments to your article with this syntax: <!-- This won't show up in the content! --> Accessibility People access online content in all kinds of different ways, and there are a few things you can do to make your posts more easily understood by a broad range of users. You can find out more about web accessibility at W3C's Introduction to Web Accessibility , but there are two main ways you can make your posts more accessible: providing alternative descriptions of any images you use, and adding appropriate headings. Providing alternative descriptions for images Some users might not be able to see or easily process images that you use in your posts. Providing an alternative description for an image helps make sure that everyone can understand your post, whether they can see the image or not. When you upload an image in the editor, you will see the following text to copy and paste into your post:  Replace the "Image description" in square brackets with a description of your image - for example:  By doing this, if someone reads your post using an assistive device like a screen reader (which turns written content into spoken audio) they will hear the description you entered. Providing headings Headings provide an outline of your post to readers, including people who can't see the screen well. Many assistive technologies (like screen readers) allow users to skip directly to a particular heading, helping them find and understand the content of your post with ease. Headings can be added in levels 1 - 6 . Avoid using a level one heading (i.e., '# Heading text'). When you create a post, your post title automatically becomes a level one heading and serves a special role on the page, much like the headline of a newspaper article. Similar to how a newspaper article only has one headline, it can be confusing if multiple level one headings exist on a page. In your post content, start with level two headings for each section (e.g. '## Section heading text'), and increase the heading level by one when you'd like to add a sub-section, for example: ## Fun facts about sloths ### Speed Sloths move at a maximum speed of 0.27 km/h! 🌊 Liquid Tags We support native Liquid tags in our editor, but have created our own custom tags as well. A list of supported custom embeds appears below. To create a custom embed, use the complete URL: {% embed https://... %} Supported URL Embeds DEV Community Comment DEV Community Link DEV Community Link DEV Community Listing DEV Community Organization DEV Community Podcast Episode DEV Community Tag DEV Community User Profile asciinema CodePen CodeSandbox DotNetFiddle GitHub Gist, Issue or Repository Glitch Instagram JSFiddle JSitor Loom Kotlin Medium Next Tech Reddit Replit Slideshare Speaker Deck SoundCloud Spotify StackBlitz Stackery Stack Exchange or Stack Overflow Twitch Twitter Twitter timeline Wikipedia Vimeo YouTube Supported Non-URL Embeds Call To Action (CTA) {% cta link %} description {% endcta %} Provide a link that a user will be redirected to. The description will contain the label/description for the call to action. Details You can embed a details HTML element by using details, spoiler, or collapsible. The summary will be what the dropdown title displays. The content will be the text hidden behind the dropdown. This is great for when you want to hide text (i.e. answers to questions) behind a user action/intent (i.e. a click). {% details summary %} content {% enddetails %} {% spoiler summary %} content {% endspoiler %} {% collapsible summary %} content {% endcollapsible %} KaTex Place your mathematical expression within a KaTeX liquid block, as follows: {% katex %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} To render KaTeX inline add the "inline" option: {% katex inline %} c = \pm\sqrt{a^2 + b^2} {% endkatex %} RunKit Put executable code within a runkit liquid block, as follows: {% runkit // hidden setup JavaScript code goes in this preamble area const hiddenVar = 42 %} // visible, reader-editable JavaScript code goes here console.log(hiddenVar) {% endrunkit %} Parsing Liquid Tags as a Code Example To parse Liquid tags as code, simply wrap it with a single backtick or triple backticks. `{% mytag %}{{ site.SOMETHING }}{% endmytag %}` One specific edge case is with using the raw tag. To properly escape it, use this format: `{% raw %}{{site.SOMETHING }} {% ``endraw`` %}` Common Gotchas Lists are written just like any other Markdown editor. If you're adding an image in between numbered list, though, be sure to tab the image, otherwise it'll restart the number of the list. Here's an example of what to do: Here's the Markdown cheatsheet again for reference.

Report Abuse joe-re Posted on Jan 12 I Built a Desktop App to Supercharge My TMUX + Claude Code Workflow # claudecode # tauri # productivity # tmux Background Until recently, I was primarily using Cursor for AI-assisted coding. The editor-centric AI integration worked really well with my development style—it made the feedback loop smooth when AI-generated code didn't match my intentions, whether I needed to manually fix it or provide additional instructions. But everything changed when Opus 4.5 was released in late November last year. Opus 4.5 delivers outputs that match my expectations far better than any previous model. Claude Code's CUI-first design also feels natural to my workflow. Now, Claude Code has become the center of my development process. I've locked in Opus 4.5 as my daily driver. I typically run multiple Claude Code sessions simultaneously—across different projects or multiple branches using git worktree. Managing notifications and checking outputs across these sessions is critical. I was using OS notifications to check in whenever changes happened, but I kept missing them. I wanted something better. So I built an app to streamline my workflow. What I Built eyes-on-claude-code It's a cross-platform desktop application built with Tauri . I've only tested it on macOS (my daily environment), but the codebase is designed to support Linux as well. My Environment & Workflow This app is primarily designed to optimize my own workflow, so the features reflect my environment and habits. I develop using Ghostty + tmux . My typical workflow looks like this: Draft ideas and design in Markdown Give instructions to Claude Code (using Plan mode for larger tasks) Review the diff of generated code, then provide additional instructions or continue Features Multi-Session Monitoring Dashboard The dashboard monitors Claude Code sessions by receiving events through hooks configured in the global settings.json . Since I keep this running during development, I designed it with a minimal, non-intrusive UI. Always-on-top mode (optional) ensures the window doesn't get buried under other apps—so you never miss a notification. Transparency settings let you configure opacity separately for active and inactive states. When inactive, you can make it nearly invisible so it doesn't get in the way. It's there in the top-right corner, barely visible. Status Display & Sound Notifications Sessions are displayed with one of four states: State Meaning Display Active Claude is working 🟢 WaitingPermission Waiting for permission approval 🔐 WaitingInput Waiting for user input (idle) ⏳ Completed Response complete ✅ Sound effects play on state changes (can be toggled off): Waiting (Permission/Input) : Alert tone (two low beeps) Completed : Completion chime (ascending two-note sound) I'm planning to add volume control and custom commands in the future—like using say to speak or playing music on completion 🎵 Git-Based Diff Viewer I usually review AI-generated changes using difit . I wanted to integrate that same flow into this app, so you can launch difit directly on changed files. Huge thanks to the difit team for building such a great tool! tmux Integration When developing, I use tmux panes and tabs to manage multiple windows. My typical setup is Claude Code on the left half, and server/commands on the right. When working across multiple projects or branches via git worktree, it's frustrating to hunt for which tmux tab has Claude Code running. So I added a tmux mirror view that lets you quickly check results and give simple instructions without switching tabs. How It Works The app uses Claude Code hooks to determine session status based on which hooks fire. Event Flow I didn't want to introduce complexity with an intermediate server for inter-process communication. So I went with a simple approach: hooks write to log files, and the app watches those files. Hooks write logs to a temporary directory ( .local/eocc/logs ), which the app monitors. Since Claude Code runs in a terminal, hooks can access terminal environment paths. This lets me grab tmux and npx paths from within hooks and pass them to the app. Mapping Hooks to Status Claude Code provides these hook events: https://code.claude.com/docs/hooks-guide Here's how I map them to session states: Event Usage Session State session_start (startup/resume) Start a session Active session_end End a session Remove session notification (permission_prompt) Waiting for approval WaitingPermission notification (idle_prompt) Waiting for input WaitingInput stop Response completed Completed post_tool_use After tool execution Active user_prompt_submit Prompt submitted Active Conclusion I've only been using Claude Code as my primary tool for about two months, and I expect my workflow will keep evolving. Thanks to AI, I can quickly build and adapt tools like this—which is exactly what makes this era so exciting. If your workflow is similar to mine, give it a try! I'd love to hear your feedback.

Posted on Jan 12 Why Your Secret Sharing Tool Needs Post-Quantum Cryptography Today # security # cryptography # webdev # privacy The "Harvest Now, Decrypt Later" Threat Quantum computers capable of breaking RSA and ECC encryption don't exist yet. But here's the problem: adversaries are already collecting encrypted data today, planning to decrypt it once quantum computers arrive. For sensitive data that needs to remain confidential for years, this is a real threat. What is Post-Quantum Cryptography? Post-quantum cryptography (PQC) uses mathematical problems that are hard for both classical AND quantum computers to solve. In August 2024, NIST standardized three PQC algorithms: ML-KEM (Kyber) - Key encapsulation ML-DSA (Dilithium) - Digital signatures SLH-DSA (SPHINCS+) - Hash-based signatures Implementing PQC in a Web Application I recently added PQC support to NoTrust.now , a zero-knowledge secret sharing tool. Here's how: Key Exchange with ML-KEM-768 // Using crystals-kyber-js library import { MlKem768 } from ' crystals-kyber-js ' ; // Receiver generates keypair const [ publicKey , privateKey ] = await MlKem768 . generateKeyPair (); // Sender encapsulates a shared secret const [ ciphertext , sharedSecret ] = await MlKem768 . encapsulate ( publicKey ); // Receiver decapsulates to get the same shared secret const decryptedSecret = await MlKem768 . decapsulate ( ciphertext , privateKey ); Enter fullscreen mode Exit fullscreen mode Hybrid Approach For defense in depth, combine PQC with classical crypto: Generate ephemeral X25519 keypair (classical) Generate ephemeral ML-KEM-768 keypair (post-quantum) Combine both shared secrets: finalKey = HKDF(x25519Secret || kyberSecret) This ensures security even if one algorithm is broken. Try It Out You can test PQC secret sharing at NoTrust.now/createpqc . The encryption happens entirely in your browser - zero-knowledge architecture means the server never sees your plaintext.

Report Abuse Victor de la Fouchardière Posted on Aug 16, 2020 🤝 Promise.allSettled() VS Promise.all() in JavaScript 🍭 # node # webdev # javascript # beginners Hello ! 🧑🌾 Promises are available since ES2015 to simplify the handling of asynchronous operations. Let's discover 2 Promises and their differences: Promise.allSettled(iterable) Promise.all(iterable) Both of them take an iterable and return an array containing the fulfilled Promises. ❓ So, what is the difference between them ? Promise.all() 🧠 The Promise. all() method takes an iterable of promises as an input, and returns a single Promise that resolves to an array of the results of the input promises. All resolved As you can see, we are passing an array to Promise.all. And when all three promises get resolved, Promise.all resolves and the output is consoled. Now, let's see if one promise is not resolved , and so, if this one is reject. What was the output ? 🛑 1 failed Promise.all is rejected if at least one of the elements are rejected . For example, we pass 2 promises that resolve and one promise that rejects immediately, then Promise.all will reject immediately. Promise.allSettled() 🦷 Since ES2020 you can use Promise.allSettled . It returns a promise that always resolves after all of the given promises have either fulfilled or rejected, with an array of objects that each describes the outcome of each promise. For each outcome object, a status string is present : fulfilled ✅ rejected ❌ The value (or reason) reflects what value each promise was fulfilled (or rejected) with. Have a close look at following properties ( status , value , reason ) of resulting array. Differences 👬 Promise.all will reject as soon as one of the Promises in the array rejects. Promise.allSettled will never reject, it will resolve once all Promises in the array have either rejected or resolved. Supported Browsers 🚸 The browsers supported by JavaScript Promise.allSettled() and Promise.all() methods are listed below: Google Chrome Microsoft Edge Mozilla Firefox Apple Safari Opera Cheers 🍻 🍻 🍻 If you enjoyed this article you can follow me on Twitter or here on dev.to where I regularly post bite size tips relating to HTML, CSS and JavaScript. 📦 GitHub Profile: The RIGHT Way to Show your latest DEV articles + BONUS 🎁 Victor de la Fouchardière ・ Aug 5 '20 #github #markdown #showdev #productivity 🍦 Cancel Properly HTTP Requests in React Hooks and avoid Memory Leaks 🚨 Victor de la Fouchardière ・ Jul 29 '20 #react #javascript #tutorial #showdev Top comments (14) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Lucas Pereira de Souza Posted on Dec 29, 2025 Decimal: futuro tipo numérico do JavaScript # javascript # news # programming ## Decimal: A Necessidade de Precisão em JavaScript e o Futuro com TC39 A computação, em sua essência, lida com números. No entanto, a forma como representamos e manipulamos esses números pode ter implicações profundas, especialmente em domínios onde a precisão é crucial, como em aplicações financeiras, científicas ou de engenharia. O JavaScript, historicamente, tem enfrentado desafios nessa área com sua representação nativa de números de ponto flutuante, abrindo a porta para a necessidade de tipos de dados mais precisos como o Decimal . O Problema com Ponto Flutuante em JavaScript O JavaScript utiliza o padrão IEEE 754 para representar números de ponto flutuante de dupla precisão (64 bits). Embora eficiente para a maioria dos casos de uso, essa representação pode levar a imprecisões sutis em certas operações. A razão fundamental reside na forma como números decimais são convertidos para binário. Muitos números decimais que parecem simples em base 10 (como 0.1 ou 0.2) não possuem uma representação binária finita exata. Isso resulta em pequenas discrepâncias que podem se acumular e causar erros inesperados. Considere um exemplo clássico: // Exemplo em JavaScript puro let result = 0.1 + 0.2 ; console . log ( result ); // Saída: 0.30000000000000004 Enter fullscreen mode Exit fullscreen mode Essa saída, 0.30000000000000004 , em vez do esperado 0.3 , demonstra o problema inerente à representação de ponto flutuante. Em aplicações financeiras, onde centavos importam, esse tipo de imprecisão é inaceitável. A Ascensão do Decimal e o Status da TC39 Para mitigar esses problemas, bibliotecas de Decimal surgiram como soluções populares. Essas bibliotecas implementam números decimais usando representações internas que garantem a precisão exata, geralmente armazenando os números como strings ou arrays de dígitos. No entanto, a necessidade de uma solução nativa e padronizada levou a propostas para inclusão de um tipo Decimal na especificação ECMAScript (a base do JavaScript). A proposta para um tipo Decimal alcançou o estágio 2 (Working Draft) do processo de padronização da TC39 (Technical Committee 39), o comitê responsável pela evolução do ECMAScript. Isso significa que a proposta está sendo ativamente desenvolvida e revisada, com o objetivo de se tornar um recurso padrão da linguagem. O status atual da proposta indica um caminho promissor para a adição nativa de um tipo Decimal , o que simplificaria o desenvolvimento e eliminaria a dependência de bibliotecas externas para muitos casos de uso. Comparando Decimal com BigInt É importante não confundir Decimal com BigInt . Enquanto ambos abordam limitações dos números primitivos do JavaScript, eles servem a propósitos diferentes: Decimal : Foca na precisão exata para números com casas decimais , resolvendo os problemas de ponto flutuante em operações que envolvem frações e cálculos monetários. Ele lida com a representação precisa de números que podem não ter uma representação binária finita exata. BigInt : Introduzido na especificação ECMAScript 2020, o BigInt é um tipo numérico primitivo que pode representar inteiros arbitráriamente grandes , superando o limite do Number.MAX_SAFE_INTEGER . Ele é ideal para trabalhar com números inteiros que excedem a capacidade dos números de ponto flutuante padrão. Vamos ilustrar com exemplos em TypeScript, demonstrando boas práticas: // Exemplo de uso de uma biblioteca Decimal (simulada para fins educacionais) // Em um cenário real, você usaria uma biblioteca como 'decimal.js' ou 'big.js' /** * Representa um número decimal com precisão exata. * Em uma implementação real, isso seria uma classe que encapsula a lógica. */ class PreciseDecimal { private value : string ; // Armazena o número como string para precisão constructor ( num : number | string ) { // Em uma implementação real, haveria validação e conversão robusta. this . value = String ( num ); } add ( other : PreciseDecimal ): PreciseDecimal { // Lógica complexa de adição decimal aqui. // Para este exemplo, apenas simulamos o resultado correto. const num1 = parseFloat ( this . value ); const num2 = parseFloat ( other . value ); // Note que esta simulação ainda usa parseFloat internamente para demonstração, // uma implementação real não faria isso para a operação principal. return new PreciseDecimal (( num1 + num2 ). toFixed ( 10 )); // toFixed para simular resultado preciso } // Outros métodos como subtract, multiply, divide, etc. toString (): string { return this . value ; } } // Utilizando a classe simulada PreciseDecimal const amount1 = new PreciseDecimal ( 0.1 ); const amount2 = new PreciseDecimal ( 0.2 ); const preciseSum = amount1 . add ( amount2 ); console . log ( `Soma decimal precisa: ${ preciseSum . toString ()} ` ); // Saída esperada: 0.3 (ou similar, dependendo da precisão configurada) // Exemplo com BigInt // Trabalhando com inteiros muito grandes const veryLargeNumber1 : bigint = BigInt ( \ " 900719925474099100 \" ); // Excedendo MAX_SAFE_INTEGER const veryLargeNumber2: bigint = BigInt( \" 100 " ); const bigIntSum : bigint = veryLargeNumber1 + veryLargeNumber2 ; console . log ( `Soma BigInt: ${ bigIntSum } ` ); // Saída: 900719925474099200 Enter fullscreen mode Exit fullscreen mode Conclusão A precisão é um pilar fundamental em muitas aplicações. Enquanto o JavaScript evolui, a necessidade de lidar com números decimais de forma precisa se torna cada vez mais premente. A proposta de um tipo Decimal na TC39 representa um passo significativo em direção a um ecossistema JavaScript mais robusto e confiável. Compreender a diferença entre Decimal e BigInt é crucial para escolher a ferramenta certa para o trabalho: Decimal para precisão com casas decimais e BigInt para inteiros de grande magnitude. À medida que o padrão evolui, podemos esperar que o desenvolvimento de aplicações de alta precisão em JavaScript se torne mais direto e menos propenso a erros sutis.

Report Abuse Esimit Karlgusta Posted on Jan 13 How to Handle Stripe and Paystack Webhooks in Next.js (The App Router Way) # api # nextjs # security # tutorial The #1 reason developers struggle with SaaS payments is Webhook Signature Verification. You set everything up, the test payment goes through, but your server returns a 400 Bad Request or a Signature Verification Failed error. In the Next.js App Router, the problem usually stems from how the request body is parsed. Stripe and Paystack require the raw request body to verify the signature, but Next.js often tries to be helpful by parsing it as JSON before you can get to it. Here is the "Golden Pattern" for handling this in 2026. 1. The Route Handler Setup Create a file at app/api/webhooks/route.ts . You must export a config object (if using older versions) or use the req.text() method in the App Router to prevent automatic parsing. import { NextResponse } from " next/server " ; import crypto from " crypto " ; export async function POST ( req : Request ) { // 1. Get the raw body as text const body = await req . text (); // 2. Grab the signature from headers const signature = req . headers . get ( " x-paystack-signature " ) || req . headers . get ( " stripe-signature " ); if ( ! signature ) { return NextResponse . json ({ error : " No signature " }, { status : 400 }); } // 3. Verify the signature (Example for Paystack) const hash = crypto . createHmac ( " sha512 " , process . env . PAYSTACK_SECRET_KEY ! ) . update ( body ) . digest ( " hex " ); if ( hash !== signature ) { return NextResponse . json ({ error : " Invalid signature " }, { status : 401 }); } // 4. Now parse the body and handle the event const event = JSON . parse ( body ); if ( event . event === " charge.success " ) { // Handle successful payment in your database console . log ( " Payment successful for: " , event . data . customer . email ); } return NextResponse . json ({ received : true }, { status : 200 }); } Enter fullscreen mode Exit fullscreen mode 2. The Middleware Trap If you have global middleware protecting your routes, ensure your webhook path is excluded. Otherwise, the payment provider will hit your login page instead of your API. 3. Why this matters for your SaaS If your webhooks fail, your users won't get their "Pro" access, and your churn will skyrocket. Handling this correctly is the difference between a side project and a real business. I have spent a lot of time documenting these "Gotchas" while building my MERN stack projects. If you want to see a full implementation of this including Stripe, Paystack, and database logic, check out my deep dive here: How to add Stripe or Paystack payments to your SaaS . Digging Deeper If you are tired of debugging the same boilerplate over and over, you might find my SassyPack overview helpful. I built it specifically to solve these "Day 1" technical headaches for other founders. Happy coding!

Candidate Recommendation is an explicit call for implementations, indicating that the document has been reviewed by all other W3C Working Groups, that the specification is stable, and appropriate for implementation. OWL is a language for defining structured, Web-based ontologies which enable richer integration and interoperability of data across application boundaries. Early adopters of these standards include bioinformatics and medical communities, corporate enterprise and governments. OWL enables a range of descriptive applications including managing web portals, collections management, content-based searches, enabling intelligent agents, web services and ubiquitous computing. "OWL is an important step for making data on the Web more machine processable and reusable across applications, " said Tim Berners-Lee, W3C Director. "We're encouraged to see OWL already being used as an open standard for deploying large scale ontologies on the Web." OWL is specified in 6 documents: The OWL Overview ; OWL Semantics and Abstract Syntax ; OWL Use Cases and Requirements ; OWL Test Cases , OWL Guide , and the OWL Reference . Read the FAQ for more details on OWL. OWL Delivers Ontologies that Work on the Web OWL is a Web Ontology language. Where earlier languages have been used to develop tools and ontologies for specific user communities (particularly in the sciences and in company-specific e-commerce applications), they were not defined to be compatible with the architecture of the World Wide Web in general, and the Semantic Web in particular. OWL rectifies this by using both URIs for naming and the linking provided by RDF to add the following capabilities to ontologies: Ability to be distributed across many systems Scalable to Web needs Compatible with Web standards for accessibility and internationalization. Open and extensible OWL provides a language for defining structured, Web-based ontologies which delivers richer integration and interoperability of data among descriptive communities. OWL builds on RDF Model and Schema and adds more vocabulary for describing properties and classes: among others, relations between classes (e.g. disjointness), cardinality (e.g. "exactly one"), equality, richer typing of properties, characteristics of properties (e.g. symmetry), and enumerated classes. Already there are multiple implementations and demonstrations of OWL, which are available to the public. The OWL Documents Produced by W3C The W3C Web Ontology Working Group has produced six OWL documents. Each is aimed at different segments of those wishing to learn, use, implement or understand the OWL language. Documents include - a presentation of the use cases and requirements that motivated OWL - an overview document which briefly explains the features of OWL and how they can be used - a comprehensive Guide that walks through the features of OWL with many examples of the use of OWL features - a reference document that provides the details of every OWL feature - a test case document , and test suite , providing over a hundred tests that can be used for making sure that OWL implementations are consistent with the language design - a document presenting the semantics of OWL and details of the mapping from OWL to RDF. The Candidate Recommendation phase for the OWL documents is estimated to last at least four weeks, at which time the Working Group will evaluate new implementations and comments on the drafts. OWL's Place in the Architecture of the Semantic Web: XML, RDF, and Ontologies Much has been written about the Semantic Web, as if it is a replacement technology for the Web we know today. In fact, the Semantic Web is made through incremental changes, by bringing machine-readable descriptions to the data and documents already on the Web. With both descriptions and ways to connect, compare, and contrast them, it's possible to build applications, tools, search engines, agents - all with no apparent change to Web pages. W3C's Semantic Web Activity builds on work done in other W3C Activities, such as the XML Activity. Its focus is to develop standard technologies, on top of XML, that support the growth of the Semantic Web. At the foundation, XML provides a set of rules for creating vocabularies that can bring structure to both documents and data on the Web. XML gives clear rules for syntax; XML Schemas then serve as a method for composing XML vocabularies. XML is a powerful, flexible surface syntax for structured documents, but imposes no semantic constraints on the meaning of these documents. RDF - the Resource Description Framework - is a standard a way for simple descriptions to be made. What XML is for syntax, RDF is for semantics - a clear set of rules for providing simple descriptive information. RDF Schema then provides a way for those descriptions to be combined into a single vocabulary. What's needed next is a way to develop subject - or domain - specific vocabularies. That is the role of an ontology. An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are used by people, databases, and applications that need to share subject-specific (domain) information - like medicine, tool manufacturing, real estate, automobile repair, financial management, etc. Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them. They encode knowledge in a domain and also knowledge that spans domains. In this way, they make that knowledge reusable. Industrial and Academic Leaders Move OWL Forward The W3C Web Ontology Working Group carries a complement of industrial and academic expertise, lending the depth of research and product implementation experience necessary for building a robust ontology language system. Participants include representatives from Agfa-Gevaert N. V; Daimler Chrysler Research and Technology; DARPA; Defense Information Systems Agency (DISA); EDS; Fujitsu; Forschungszentrum Informatik (FZI); Hewlett Packard Company; Ibrow; IBM; INRIA; Ivis Group; Lucent; University of Maryland; Mondeca; Motorola; National Institute of of Standards and Technology (NIST); Network Inference, Nokia; Philips, University of Southampton; Stanford University; Sun Microsystems; Unicorn Solutions along with invited experts from German Research Center for Artificial Intelligence (DFKI) Gmbh; the Interoperability Technology Association for Information Processing, Japan (INTAP); and the University of West Florida. OWL brings together research from a number of groups that have been developing languages in which to express ontological expressions on the web . OWL has its origins in two major research efforts: a draft language known as the DARPA Agent Markup Language Ontology notations ( DAML-ONT ) and Ontology Interface Layer ( OIL ) developed by European researchers with the support of the European Commission. Since then, an ad hoc group of researchers formed the Joint US/EU committee on Agent Markup Languages and released a new version of this language which merges DAML with the OIL. The documents released today reflect the collaborative work of international researchers with industrial participants working together the World Wide Web Consortium. About the World Wide Web Consortium [W3C] The W3C was created to lead the Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. It is an international industry consortium jointly run by the MIT Laboratory for Computer Science (MIT LCS) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France and Keio University in Japan. Services provided by the Consortium include: a repository of information about the World Wide Web for developers and users, and various prototype and sample applications to demonstrate use of new technology. To date, nearly 400 organizations are Members of the Consortium. For more information see http://www.w3.org/ Contact Janet Daly, < janet@w3.org >, +1.617.253.5884 or +1.617.253.2613 Frequently Asked Questions on W3C's Web Ontology Language (OWL) Status: this FAQ is no longer maintained. For a new, up-to-date FAQ, see the Semantic Web FAQ . Q. What is an ontology? A. Although the concept of ontology has been around for a very long time in philosophy, in recent years it has become identified with computers as a machine readable vocabulary that is specified with enough precision to allow differing terms to be precisely related. More precisely, from the OWL Requirements Document : An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are used by people, databases, and applications that need to share domain information (a domain is just a specific subject area or area of knowledge, like medicine, tool manufacturing, real estate, automobile repair, financial management, etc.). Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them [...]. They encode knowledge in a domain and also knowledge that spans domains. In this way, they make that knowledge reusable. Q. How is OWL different from earlier ontology languages? A. OWL is a Web Ontology language. Where earlier languages have been used to develop tools and ontologies for specific user communities (particularly in the sciences and in company-specific e-commerce applications), they were not defined to be compatible with the architecture of the World Wide Web in general, and the Semantic Web in particular. OWL rectifies this by providing a language which uses the linking provided by RDF to add the following capabilities to ontologies: Ability to be distributed across many systems Scalable to Web needs Compatible with Web standards for accessibility and internationalization. Open and extensible Q. What can Web Ontologies be used for? A. The Web Ontology Working Group identified major use cases of ontologies on the Web and described these in the Use Cases and Requirements document . A survey of implemented applications (using earlier web ontology languages) was made with about 25 actually deployed systems identified. The WG categorized these into six main areas, as follows: Web Portals Categorization rules used to enhance search Multimedia Collections Content-based searches for non-text media Corporate Web Site Management Automated Taxonomical Organization of data and documents Mapping Between Corporate Sectors (mergers!) Design Documentation Explication of "derived" assemblies (e.g. the wing span of an aircraft) Explicit Management of Constraints Intelligent Agents Expressing User Preferences and/or Interests Content Mapping between Web sites Web Services and Ubiquitous Computing Web Service Discovery and Composition Rights Management and Access Control Q. Who is implementing OWL tools and applications? A. A large number of organizations have been exploring the use of OWL, with many tools currently available. The Working Group is maintaining a list of implementations and demonstrations . In addition, both the US government (via DARPA and NSF) and the European Union (via the 5th and 6th generation frameworks of the IST program) have invested in web ontology language development. Most of the systems currently using DAML, OIL and DAML+OIL (the predecessor languages that OWL was based on) are now migrating to OWL. In addition, a number of ontology language tools, such as the widely used Protege system , now provide OWL support. Q. Are there OWL ontologies available already? A. There are a large number of ontologies available on the Web in OWL. There is an ontology library at DAML ontology library , which contains about 250 examples written in OWL or DAML+OIL (a converter from DAML+OIL to OWL is available on the web). In addition, several large ontologies have been released in OWL. These include a cancer ontology in OWL developed by the US National Cancer Institute's Center for Bioinformatics, which contains about 17,000 cancer related terms and their definitions, and an OWL version of the well-known GALEN medical ontology , developed at the University of Manchester. Q. What does OWL add that RDF-schema doesn't? A. Owl extends RDFS to allow for the expression of complex relationships between different RDFS classes and of more precise constraints on specific classes and properties. Example of these include: - the means to limit the properties of classes with respect to number and type, - the means to infer that items with various properties are members of a particular class - the means to determine if all members of a class will have a particular property, or if only some of them might - the means to distinguish one-to-one from many-to-one or one-to-many relationships, allowing the "foreign keys" of a database to be represented in an ontology - the means to express relationships between classes defined in different documents across the web, - the means to construct new classes out of the unions, intersections and complements of other classes, and - the means to constrain range and domain to specific class/property combinations. The OWL Guide provides examples of all of these in the area of describing food and wine. Q. What documents are in the OWL document set? A. The Working Group has produced six documents each aimed at different segments of those wishing to learn, use, implement or understand the OWL language. Our documents include - a presentation of the use cases and requirements that motivated OWL - an overview document which briefly explains the features of OWL and how they can be used - a comprehensive Guide that provides a walk-through of the features of OWL with many examples of the use of OWL features - a reference document that provides the details of every OWL feature - a test case document , and test suite , providing over a hundred tests that can be used for making sure that OWL implementations are consistent with the language design - a document presenting the semantics of OWL and details of the mapping from OWL to RDF (This document presents the model theoretical details of every feature of OWL so that those implementing complete OWL reasoners can guarantee algorithmic compliance with all aspects of the language design). Q. What is new about ontologies on the Semantic Web? How do they differ from expert systems and the other artificial intelligence (AI) technologies promoted in the 1980s? A. The relation between the Semantic Web, and OWL in particular, to work in AI is somewhat parallel to the relation between the Web and the hypertext community -- based on some of the same motivations, but with a very different architecture that drastically changes the ways in which the technology can be deployed. In a widely cited article from Scientific American , Berners-Lee, Hendler and Lassila wrote: For the semantic web to function, computers must have access to structured collections of information and sets of inference rules that they can use to conduct automated reasoning. Artificial-intelligence researchers have studied such systems since long before the Web was developed. Knowledge representation, as this technology is often called, is currently in a state comparable to that of hypertext before the advent of the Web: it is clearly a good idea, and some very nice demonstrations exist, but it has not yet changed the world. It contains the seeds of important applications, but to realize its full potential it must be linked into a single global system. The OWL language is a major step towards developing that potential. Q. What does the acronym "OWL" stand for? A. Actually, OWL is not a real acronym. The language started out as the "Web Ontology Language" but the Working Group disliked the acronym "WOL." We decided to call it OWL. The Working Group became more comfortable with this decision when one of the members pointed out the following justification for this decision from the noted ontologist A.A. Milne who, in his influential book "Winnie the Pooh" stated of the wise character OWL: "He could spell his own name WOL, and he could spell Tuesday so that you knew it wasn't Wednesday..."

Report Abuse Michele Carino Posted on Dec 30, 2025 Il Bug della Dignità: Cronaca di un’illusione ereditaria # discuss # career # mentalhealth Una riflessione sulla cultura, la perdita e la promessa infranta della meritocrazia. Sono un informatico con vent’anni di esperienza, un uomo cresciuto in una casa dove i libri erano così tanti da fare da isolante tra le camere. Mamma professoressa di matematica, papà ingegnere elettrotecnico. I libri erano il simbolo della nostra promessa: l’idea che la cultura ci avrebbe portato in alto, ci avrebbe emancipato e ci avrebbe garantito il rispetto del mondo. Ho costruito la mia identità su questo pilastro, convinto che la logica e lo studio fossero il mio passaporto per la libertà. Invece, per vent'anni anni, ho assistito al fallimento di quel patto. Ho visto 'figli di papà' fare impresa senza la minima capacità razionale, occupando spazi per puro diritto di nascita mentre io, nonostante le competenze, dovevo lottare ogni giorno per sbarcare il lunario. Ho visto il mio nucleo familiare frantumarsi e mia madre spegnersi, tradita da una demenza fronto-temporale e abbandonata da uno Stato che ha preferito divorare la sua pensione per la retta di una casa di cura piuttosto che onorare la sua vita. In questi mesi, è scomparsa da poco, ho dovuto buttare i suoi libri, piangendo su ogni volume che finiva nel sacco, sentendo che stavo smaltendo i resti di un’illusione. Oggi, però, sono entrato in una biblioteca. E inaspettatamente, tra quegli scaffali, mi sono sentito di nuovo a casa. Sono tornato bambino, avvolto da quell'odore di carta che un tempo mi proteggeva. Lavorare da lì, circondato da quel silenzio antico, ha spento il rumore del mondo esterno. Per la prima volta dopo tanto tempo, ho ritrovato la serenità di fare e progettare per il puro gusto di farlo. Senza chiedermi il perché, senza il peso dell'ingiustizia, senza l'ombra dei privilegiati che mi calpestano. Nella mia pancia c'è ancora la rabbia dei miei genitori, ma oggi, tra questi libri, ho ripreso in mano il mio codice. Ho smesso di cercare una logica nel tradimento del sistema e ho ricominciato a costruire, semplicemente perché questo è ciò che sono. Oltre le macerie, oltre l'abbandono, la mia mente è ancora la mia casa. Vorrei poter piangere tutte le lacrime dovute al rivederci così dove non ci aspettavamo di essere nonostante tutto eppure so che l'unica soluzione è la resa, l'accettazione, il far finta idi niente per evitare di continuare a infliggersi dolore. E mi chiedo se una famiglia davvero evoluta sia quella che sprona i figli a fare soldi e realizzarsi economicamente o quella che vuole che essi siano studiosi e alfieri del progresso umano mettendo in secondo piano l'avere.

Report Abuse Daniel for Datalaria Posted on Jan 13 • Originally published at datalaria.com Proyecto Weather Service (Parte 2): Construyendo el Frontend Interactivo con GitHub Pages o Netlify y JavaScript # frontend # javascript # spanish # tutorial En la primera parte de esta serie , sentamos las bases de nuestro servicio meteorológico global. Construimos un script de Python para obtener datos del clima de OpenWeatherMap, los almacenamos eficientemente en ficheros CSV separados por ciudad y automatizamos todo el proceso de recolección utilizando GitHub Actions. Nuestro "robot" está diligentemente recopilando datos 24/7. Pero, ¿de qué sirven los datos si no puedes verlos? Hoy, cambiamos nuestro enfoque al frontend : la construcción de un dashboard interactivo y fácil de usar que permita a cualquiera explorar los datos meteorológicos que hemos recopilado. Aprovecharemos el poder del alojamiento de sitios estáticos con GitHub Pages o Netlify , utilizaremos JavaScript "vainilla" para darle vida y nos apoyaremos en algunas excelentes librerías para el manejo y la visualización de datos. ¡Hagamos que nuestros datos brillen! Alojamiento Web Gratuito: GitHub Pages vs. Netlify El primer obstáculo para cualquier proyecto web es el alojamiento. Los servidores tradicionales pueden ser costosos y complejos de gestionar. Siguiendo nuestra filosofía "serverless y gratis", tanto GitHub Pages como Netlify son soluciones perfectas para alojar sitios web estáticos directamente desde tu repositorio de GitHub. Opción 1: GitHub Pages Permite alojar sitios web estáticos directamente desde tu repositorio de GitHub. La activación es trivial: Ve a Settings > Pages en tu repositorio. Selecciona tu rama main (o la rama que contenga tu contenido web) como fuente. Elige la carpeta /root (o una carpeta /docs si lo prefieres) como la ubicación de tus archivos web. Haz clic en Save . Y así, tu archivo index.html (y cualquier recurso vinculado) se vuelve accesible públicamente en una URL como https://tu-usuario.github.io/tu-nombre-de-repositorio/ . ¡Sencillo, efectivo y gratuito! 🚀 Opción 2: Netlify (¡la elección final para este proyecto!) Para este proyecto, finalmente he optado por Netlify por su flexibilidad, la facilidad para gestionar dominios personalizados y su integración con el despliegue continuo. Además, me permite alojar el proyecto directamente bajo mi dominio de Datalaria ( https://datalaria.com/apps/weather/ ). Pasos para desplegar en Netlify: Conectar tu Repositorio : Inicia sesión en Netlify. Haz clic en "Add new site" y luego en "Import an existing project". Conecta tu cuenta de GitHub y selecciona el repositorio de tu proyecto Weather Service. Configuración de Despliegue : Owner : Tu cuenta de GitHub. Branch to deploy : main (o la rama donde tengas tu código frontend). Base directory : Deja esto vacío si tu index.html y assets están en la raíz del repositorio, o especifica una subcarpeta si es el caso (ej., /frontend ). Build command : Déjalo vacío, ya que nuestro frontend es puramente estático sin necesidad de un paso de build (sin frameworks como React/Vue). Publish directory : . (o la subcarpeta que contenga tus archivos estáticos, ej., /frontend ). Desplegar Sitio : Haz clic en "Deploy site". Netlify tomará tu repositorio, lo desplegará y te proporcionará una URL aleatoria. Dominio Personalizado (Opcional pero recomendado) : Para usar un dominio como datalaria.com/apps/weather/ : Ve a Site settings > Domain management > Domains > Add a custom domain . Sigue los pasos para añadir tu dominio y configurarlo con los DNS de tu proveedor (añadiendo registros CNAME o A ). Para la ruta específica ( /apps/weather/ ), necesitarás configurar una "subcarpeta" o "base URL" en tu aplicación si no está directamente en la raíz del dominio. En este caso, nuestro index.html está diseñado para ser servido desde una subruta. Netlify gestiona esto de forma transparente una vez que el sitio está desplegado y tu dominio configurado. ¡Así de sencillo! Cada git push a tu rama configurada activará un nuevo despliegue en Netlify, manteniendo tu dashboard siempre actualizado. La Pila Tecnológica del Frontend: HTML, CSS y JavaScript (con una pequeña ayuda) Para este dashboard, opté por un enfoque ligero: HTML puro para la estructura, un poco de CSS para los estilos y JavaScript "vainilla" (sin frameworks complejos) para la interactividad. Para manejar tareas específicas, incorporé dos librerías fantásticas: PapaParse.js : El mejor parser de CSV del lado del cliente para el navegador. Es el puente entre nuestros archivos CSV en bruto y las estructuras de datos de JavaScript que necesitamos para la visualización. Chart.js : Una potente y flexible librería de gráficos JavaScript que facilita enormemente la creación de gráficos bonitos, responsivos e interactivos. La Lógica del Dashboard: Dando Vida a los Datos en index.html Nuestro index.html actúa como el lienzo principal, orquestando la obtención, el parseo y la representación de los datos meteorológicos. 1. Carga Dinámica de Ciudades En lugar de codificar una lista de ciudades, queremos que nuestro dashboard se actualice automáticamente si añadimos nuevas ciudades en el backend. Lo logramos obteniendo un simple archivo ciudades.txt (que contiene un nombre de ciudad por línea) y poblando dinámicamente un elemento desplegable <select> utilizando la API fetch de JavaScript. const citySelector = document . getElementById ( ' citySelector ' ); let myChart = null ; // Variable global para almacenar la instancia de Chart.js async function cargarListaCiudades () { try { const response = await fetch ( ' ciudades.txt ' ); const text = await response . text (); // Filtramos las líneas vacías del archivo de texto const ciudades = text . split ( ' \n ' ). filter ( line => line . trim () !== '' ); ciudades . forEach ( ciudad => { const option = document . createElement ( ' option ' ); option . value = ciudad ; option . textContent = ciudad ; citySelector . appendChild ( option ); }); // Cargamos la primera ciudad por defecto al inicio de la página if ( ciudades . length > 0 ) { cargarYDibujarDatos ( ciudades [ 0 ]); } } catch ( error ) { console . error ( ' Error cargando la lista de ciudades: ' , error ); // Opcional: Mostrar un mensaje de error amigable al usuario } } // Disparamos la carga de ciudades cuando el DOM esté completamente cargado document . addEventListener ( ' DOMContentLoaded ' , cargarListaCiudades ); Enter fullscreen mode Exit fullscreen mode 2. Reacción a la Selección del Usuario Cuando un usuario selecciona una ciudad del desplegable, necesitamos responder de inmediato. Un addEventListener en el elemento <select> detecta el evento change y llama a nuestra función principal para obtener y dibujar los datos de la ciudad recién seleccionada. citySelector . addEventListener ( ' change ' , ( event ) => { const ciudadSeleccionada = event . target . value ; cargarYDibujarDatos ( ciudadSeleccionada ); }); Enter fullscreen mode Exit fullscreen mode 3. Obtención, Parseo y Dibujado de Datos Esta es la función central donde todo cobra vida. Es responsable de: Construir la URL para el archivo CSV específico de la ciudad (ej., datos/León.csv ). Utilizar Papa.parse para descargar y procesar el contenido del CSV directamente en el navegador. PapaParse maneja la obtención y el parseo asíncronos, lo que lo hace increíblemente fácil. Extraer las etiquetas (fechas) y los datos (temperaturas) relevantes del CSV parseado para Chart.js. ¡Crucial! : Antes de dibujar un nuevo gráfico, debemos destruir la instancia anterior de Chart.js ( if (myChart) { myChart.destroy(); } ). ¡Olvidar este paso lleva a gráficos superpuestos y problemas de rendimiento! 💥 Crear una nueva instancia de Chart() con los datos actualizados. Adicionalmente, llama a una función para cargar y mostrar la predicción de IA para esa ciudad, integrándola sin problemas en el dashboard. function cargarYDibujarDatos ( ciudad ) { const csvUrl = `datos/ ${ ciudad } .csv` ; // Nota la carpeta 'datos/' de la Parte 1 const ctx = document . getElementById ( ' weatherChart ' ). getContext ( ' 2d ' ); Papa . parse ( csvUrl , { download : true , // Indica a PapaParse que descargue el archivo header : true , // Trata la primera fila como encabezados skipEmptyLines : true , complete : function ( results ) { const datosClimaticos = results . data ; // Extraer etiquetas (fechas) y datos (temperaturas) const etiquetas = datosClimaticos . map ( fila => fila . fecha_hora . split ( ' ' )[ 0 ]); // Extraer solo la fecha const tempMax = datosClimaticos . map ( fila => parseFloat ( fila . temp_max_c )); const tempMin = datosClimaticos . map ( fila => parseFloat ( fila . temp_min_c )); // Destruir la instancia de gráfico anterior si existe para evitar superposiciones if ( myChart ) { myChart . destroy (); } // Crear una nueva instancia de Chart.js myChart = new Chart ( ctx , { type : ' line ' , data : { labels : etiquetas , datasets : [{ label : `Temp Máx (°C) - ${ ciudad } ` , data : tempMax , borderColor : ' rgb(255, 99, 132) ' , tension : 0.1 }, { label : `Temp Mín (°C) - ${ ciudad } ` , data : tempMin , borderColor : ' rgb(54, 162, 235) ' , tension : 0.1 }] }, options : { // Opciones del gráfico para responsividad, título, etc. responsive : true , maintainAspectRatio : false , scales : { y : { beginAtZero : false } }, plugins : { legend : { position : ' top ' }, title : { display : true , text : `Datos Históricos del Clima para ${ ciudad } ` } } } }); // Cargar y mostrar la predicción de IA cargarPrediccion ( ciudad ); }, error : function ( err , file ) { console . error ( " Error al parsear el CSV: " , err , file ); // Opcional: mostrar un mensaje de error amigable en el dashboard if ( myChart ) { myChart . destroy (); } // Limpiar gráfico si falla la carga } }); } Enter fullscreen mode Exit fullscreen mode 4. Mostrar Predicciones de IA La integración de las predicciones de IA (en las que profundizaremos en la Parte 3) también se gestiona desde el frontend. El backend genera un archivo predicciones.json , y nuestro JavaScript simplemente obtiene este JSON, encuentra la predicción para la ciudad seleccionada y la muestra. async function cargarPrediccion ( ciudad ) { const predictionElement = document . getElementById ( ' prediction ' ); try { const response = await fetch ( ' predicciones.json ' ); const predicciones = await response . json (); if ( predicciones && predicciones [ ciudad ]) { predictionElement . textContent = `Predicción de Temp. Máx. para mañana: ${ predicciones [ ciudad ]. toFixed ( 1 )} °C` ; } else { predictionElement . textContent = ' Predicción no disponible. ' ; } } catch ( error ) { console . error ( ' Error cargando predicciones: ' , error ); predictionElement . textContent = ' Error al cargar la predicción. ' ; } } Enter fullscreen mode Exit fullscreen mode Conclusión (Parte 2) ¡Hemos transformado los datos en bruto en una experiencia atractiva e interactiva! Al combinar el alojamiento estático de GitHub Pages o Netlify, JavaScript "vainilla" para la lógica, PapaParse.js para el manejo de CSV y Chart.js para visualizaciones hermosas, hemos construido un frontend potente que es a la vez gratuito y muy efectivo. El dashboard ahora proporciona información inmediata sobre los patrones climáticos históricos de cualquier ciudad seleccionada. Pero, ¿qué pasa con el futuro? En la tercera y última parte de esta serie , nos adentraremos en el emocionante mundo del Machine Learning para añadir una capa predictiva a nuestro servicio. Exploraremos cómo usar datos históricos para pronosticar el tiempo de mañana, convirtiendo nuestro servicio en un verdadero "oráculo" meteorológico. ¡No te lo pierdas!

Most of the time, you can write inline HTML directly into your posts. We support native Liquid tags and created some fun custom ones, too! Trying embedding a Tweet or GitHub issue in your post, using the complete URL: {% embed https://... %} . Links to unpublished posts are shareable for feedback/review. When you're ready to publish, set the published variable to true or click publish depending on the editor version, you're using Links to unpublished posts (drafts or scheduled posts) are shareable for feedback/review. These posts have a notice which reads "This URL is public but secret, so share at your own discretion." They are not visible in feeds or on your profile until published. description area in Twitter cards and open graph cards We have two editor versions . If you'd prefer to edit title and tags etc. as separate fields, switch to the "rich + markdown" option in Settings → Customization . Otherwise, continue: Front Matter Custom variables set for each post, located between the triple-dashed lines in your editor Here is a list of possibilities: title: the title of your article published: boolean that determines whether or not your article is published. tags: max of four tags, needs to be comma-separated canonical_url: link for the canonical version of the content cover_image: cover image for post, accepts a URL. The best size is 1000 x 420. series: post series name. ✍ Markdown Basics Below are some examples of commonly used markdown syntax. If you want to dive deeper, check out this cheat sheet. Bold & Italic Italics : *asterisks* or _underscores_ Bold : **double asterisks** or __double underscores__ Links I'm an inline link : [I'm an inline link](put-link-here) Anchored links (For things like a Table of Contents) ## Table Of Contents * [Chapter 1](#chapter-1) * [Chapter 2](#chapter-2) ### Chapter 1 <a name="chapter-1"></a> Inline Images When adding GIFs to posts and comments, please note that there is a limit of 200 megapixels per frame/page.  You can even add a caption using the HTML figcaption tag! Headings Add a heading to your post with this syntax: # One '#' for a h1 heading ## Two '#'s for a h2 heading ... ###### Six '#'s for a h6 heading Author Notes/Comments Add some hidden notes/comments to your article with this syntax: <!-- This won't show up in the content! --> Accessibility People access online content in all kinds of different ways, and there are a few things you can do to make your posts more easily understood by a broad range of users. You can find out more about web accessibility at W3C's Introduction to Web Accessibility , but there are two main ways you can make your posts more accessible: providing alternative descriptions of any images you use, and adding appropriate headings. Providing alternative descriptions for images Some users might not be able to see or easily process images that you use in your posts. Providing an alternative description for an image helps make sure that everyone can understand your post, whether they can see the image or not. When you upload an image in the editor, you will see the following text to copy and paste into your post:  Replace the "Image description" in square brackets with a description of your image - for example:  By doing this, if someone reads your post using an assistive device like a screen reader (which turns written content into spoken audio) they will hear the description you entered. Providing headings Headings provide an outline of your post to readers, including people who can't see the screen well. Many assistive technologies (like screen readers) allow users to skip directly to a particular heading, helping them find and understand the content of your post with ease. Headings can be added in levels 1 - 6 . Avoid using a level one heading (i.e., '# Heading text'). When you create a post, your post title automatically becomes a level one heading and serves a special role on the page, much like the headline of a newspaper article. Similar to how a newspaper article only has one headline, it can be confusing if multiple level one headings exist on a page. In your post content, start with level two headings for each section (e.g. '## Section heading text'), and increase the heading level by one when you'd like to add a sub-section, for example: ## Fun facts about sloths ### Speed Sloths move at a maximum speed of 0.27 km/h! 🌊 Liquid Tags We support native Liquid tags in our editor, but have created our own custom tags as well.

Report Abuse Paula Gearon Posted on Nov 14, 2022 Stay Classy in OWL # rdf # owl # sparql # rules In an effort to publish this quickly, I am posting without proofreading. Errata is welcome. In the last post I discussed using rules to generate RDF statements that are entailed by RDFS . This is useful stuff, but is very limited due to the lack of expressivity of RDFS. This is to be expected, since RDFS was a limited vocabulary that was released well before the full Web Ontology Language ( OWL ) was released. But if we adopt OWL, then what entailments will be valid and useful? Description Logics As shown in my first post in this series , OWL provides a vocabulary for a Description Logic. In particular, OWL2 conforms closely to a family of logics known as 𝒮ℛ𝒪ℐ𝒬. This name indicates some of the elements of the vocabulary: 𝒮: An Abbreviation for 𝒜ℒ𝒞 𝒜ℒ𝒞: Contains concepts including: Classes C , and roles r ⊤ (top, or everything ) ⊥ (bottom, or nothing ) ⊓ (conjunctions, or intersections) ⊔ (disjunctions, or unions) ¬ (negation, or inverse) ∃r.C (existential role restrictions) ∀r.C (universal role restrictions) ℋ: Class hierarchies (classes, with subclasses) ℛ: Complex role inclusion. This is both a role hierarchy (indicated by ℋ) and role composition. ℐ: Inverse roles. 𝒪: Nominals. 𝒩: Cardinality restrictions on roles. 𝒬: Qualified cardinality. This includes cardinality restrictions (indicated by 𝒩), and can also qualify them to classes. To explain each of the above: Classes are a way to classify things. Entities can be classified multiple ways, in which case we say the entity has a type of the class, or that the entity is an instance of the class. e.g. Person can be a class and the entity we name "Alice" may be an instance of Person . Roles describe relationships between entities. e.g. an entity named "Alice" may have a hasChild relationship to an entity named "Susan". Top is a universal class that every entity is an instance of. Bottom is an empty class that no entity is an instance of. Conjunctions are the combination of multiple classes where every class must apply. e.g. A wooden chair is an instance of the conjunction formed from the classes Wooden and Furniture . Disjunctions are the combination of multiple classes where one or more classes must apply. e.g. OfficeEquipment could be a disjunction of OfficeFurniture , ComputerEquipment , Stationery , and KitchenSupplies . Negation is used to create a class of everything that is not the negated class. e.g. The negation of the class of Visible things is everything that cannot be seen. That includes both physical objects, like air, but also arbitrary concepts like "imagination" or "price". It is the entire universe of things that are not in the Visible class. Existential role restrictions means that a given relationship must exist in order to be a member of a class. e.g. To be a Parent an entity must have a hasChild relationship to another entity. Universal role restrictions means that all use of a role has to be with a specific class. e.g. hasChild can be defined to always refer to instances of the class Child . Role hierarchy indicates more general or specific relationships between roles. This creates sub-property and super-property relationships and is roughly analogous to sub-classes and super-classes. e.g. hasDaughter is a more specific role than hasChild , while hasDescendent is a more general role. So hasDaughter is a sub-property for hasChild , and hasChild is a sub-property for hasDescendent . Inverse roles refers to the relationship that goes in the opposite direction between entities. e.g. hasParent is the inverse role to hasChild . Nominals describes a class of items that is defined by its membership in the class. e.g. PresidentOfTheUnitedStates can be defined as a class of the 46 people who have had that position (as of this writing). Number restrictions (or cardinality restrictions ) refers to a minimum or maximum number of relationships. e.g. To be a member of FullTimeStudent a university might require that a student have a minimum of 4 enrolledIn relationships. Qualified cardinality is a more specific type of nominal, where the class of the relationship must apply. e.g. For a student to be a MathMajor they might require a minimum of 10 passed relationships to instances of MathSubject . OWL These constructs are all supported by OWL , and each of those constructs has a mapping to RDF . This means that for each Description Logic expression there is a way to express that expression precisely in RDF. It is data like this that was read and processed by Pellet in the Oedipus example in my initial post . The problem with systems like Pellet is that they rely on memory to explore all possibilities for the data. Consequently, they can struggle with large bodies of data, and are unable to handle large ontologies such as SNOMED CT . We have a much better chance of scaling OWL processing if we can use operations that databases are designed to provide. The principal database operation is the Query , and so the various approaches to scaling try to build on this operation. Query Rewriting One approach to identifying entailments in OWL is by using it to rewrite queries. The first to consider is a general approach to rewriting queries, where the query can be expanded to ask for parts of the ontology. For instance, consider asking for the classes a resource is an instance of: select ?class where { my : resource a ?class } Enter fullscreen mode Exit fullscreen mode This can be rewritten to consider superclasses as well: select ?class where { my : resource a / rdfs : subClassOf * ?class } Enter fullscreen mode Exit fullscreen mode Where the * modifier describes the transitive closure of the rdfs:subClassOf relationship, starting with the 0 step, meaning that it includes the step where the class is the immediate type of the resource. A more specific case is using the ontology to rewrite the query. For instance, if the property my:prop is transitive, then querying for it can always be expanded to use the + modifier. So the query: select ?related where { my : resource my : prop ?related } Enter fullscreen mode Exit fullscreen mode Would be modified to: select ?related where { my : resource my : prop + ?related } Enter fullscreen mode Exit fullscreen mode These are some trivial examples, but some great work was done on this by Héctor Pérez-Urbina in his PhD dissertation . Rules Another approach to scalable entailment is using rules. The mechanism for this is using certain existing data structures to generate new data structures that get inserted alongside the original data. I described this in the last post , where I used construct queries to obtain the data generated by each rule. The other option is to send this generated statements back into the graph by changing construct to insert . For instance, the transitive closure of the property my:prop above could be created with an update operation: insert { ?a my : prop ?c } where { ?a my : prop ?b . ?b my : prop ?c } Enter fullscreen mode Exit fullscreen mode Note that this is a single update, and not actually a full "rule". Running this will only extend all of the my:prop relations by 1 step, doubling the length to 2. But running this iteratively will extend the maximum length of the closure by doubling, so it will rapidly cover the entire closure. What we can learn from this is that rule systems can be built from query/update operations like this, but they need a mechanism for scheduling the rules to be run over and over when needed, and to stop when nothing new is being generated. The basic algorithm for doing this is called RETE , and I discussed this and an implementation at Clojure/conj 2016 . Because rules are built on a querying mechanism that is foundational to the database, they are often very fast. They also rely on the main database storage, so they can scale with the database. They allow computational complexity to be pre-calculated, with the results stored. This allows subsequent operations to rely on space complexity instead. These are very important characteristics for working with large quantities of data, and for this reason I will be focusing on this approach to entailment. Rule Justification Many OWL operations describe entailments that can be expressed as a rule. For instance, the OWL 2 Structural Specification and Functional-Style Syntax document describes many constructs with examples of what they entail. There are many examples of this, but a simple one is the Symmetric Object Property which describes that a:friend is symmetric. Consequently, if "Brian is a friend of Peter" then this entails "Peter is a friend of Brian". The general rule for symmetry can then be given as: insert { ?b ?prop ?a } where { ?a ?prop ?b . ?prop a owl : SymmetricProperty } Enter fullscreen mode Exit fullscreen mode This can seem to be a straightforward operation, but interesting insights come about when we consider exactly why these new statements are allowed to be asserted. Validity and Consistency Logic systems can be described using a pair of properties: validity and consistency. A system is valid if every interpretation of the systems leads to conclusions that are true. A system is invalid if there exists an interpretation where the conclusions are not true. A system is consistent if there exists an interpretation where the conclusions are true. A system is inconsistent if there are no interpretations where the conclusions are true. The interpretation of a system is a selection of values that conform to the system. To explain some of this, let's use the mathematical domain. In this case, the interpretation will usually be a selection of numbers to associate with values. Valid Since every possible interpretation of a valid system is true, these are also referred to as a tautology . At first glance, this does not seem that useful, however it is a very important concept. An example of a valid math expression is: | x | ≥ x The various interpretations of this system are the values that x can take in the domain of real numbers ℝ. In this case, it doesn't matter what value x takes, since the equation will always be true. This is still logic, so we can introduce an or operation, with another valid equation: x > 1 ∨ x < 2 Again, this is a tautology, as it will be true for every interpretation of x in the domain. Invalid This applies to any system which is not valid. That simply means that there exists an interpretation where truth does not hold. For instance: x > 2 This is true when x is 3 or 4, but it is not true when x is 1 or 2. Lots of systems are Invalid, since tautologies (i.e. valid systems) don't have a lot to say. Consistent A system is consistent when there exists an interpretation that leads to truth. The example invalid statement also happens to be consistent: x > 2 As already mentioned, when x is 3 then the statement is true, so this system is consistent. Inconsistent This indicates that a system is not consistent, meaning that there are no possible interpretations which can be true. For instance: x < 3 ∧ x > 4 There are no numbers that meet both of these conditions, and therefore there are no interpretations where this is true. Relations to Each Other When considered in relation to one another we see the following states for systems: Always true: Valid and Consistent Sometimes true, Sometimes false: Invalid and Consistent Always false: Invalid and Inconsistent Entailment Entailment is the operation of finding new statements that are true in every possible interpretation of a system, given its semantics. This is possible when using the Open World Assumption (OWA), since new statements can always be added, which is a concept that is sometimes expressed as, "Anyone can say Anything about Anything" (this phrase appears in an early draft of the RDF Concepts and Abstract Data Model , and also in the book " Semantic Web for the Working Ontologist ", by Allemang, Hendler, and now in the second edition, Gandon. I will refer to this book as SWWO). This cuts both ways though: not only does it mean that new statement may be created, but it also limits which statements may be created. The OWA says that there are possibly a lot of other statements that the system does not describe which could lead to a statement not being possible in every possible interpretation. When it comes to identifying new statements that can be entailed, it is a useful exercise to consider all the possible constructs that could lead to the statement leading to a falsehood, even if it requires a convoluted set of statements to get there. Tableaux One approach in using validity and consistency is to determine if a given system entails a statement using the Tableaux Algorithm. In this case, for a given system 𝑮 an entailment 𝑨 is described as: 𝑮 ⊨ 𝑨 This entailment can only be true if: 𝑮 ⋃ {¬𝑨} is inconsistent This is a useful test, because the algorithm need only discover a single false case to prove inconsistency. Pellet is an implementation of this algorithm, and while it does not scale to very large ontologies, it is nevertheless very powerful. Rules Another approach to entailment is to use rules. As mentioned above, this can be done when we know that a statement is legal in every possible interpretation of the system. There is a defined subset of possible reasoning in OWL2 which can lead to entailments via rules. This subset is called the OWL 2 RL Profile , and the rules can be found in tables 4 through to table 9 in the rules section of the OWL 2 Profiles document. It is some of these rules that I want to explore here and in other posts. Intersections A practical application of all of this can be seen in Intersections. As described in SWWO , an intersection of classes :A and :B can be described using a subclass relationship: This is described in Turtle as: : IntersectionAB rdfs: subClassOf : A, : B . Enter fullscreen mode Exit fullscreen mode Let's consider what can be inferred from this. If we have an instance of :IntersectionAB called :x , then this is represented as: : x a : IntersectionAB . Enter fullscreen mode Exit fullscreen mode The rule rdfs9 is: insert { ?zzz a ?yyy } where { ?xxx rdfs : subClassOf ?yyy . ?zzz a ?xxx } Enter fullscreen mode Exit fullscreen mode Applying this will result in :x being an instance of both :A and :B : : x a : IntersectionAB . : x a : A . : x a : B . Enter fullscreen mode Exit fullscreen mode These inferences are valid, because the definition of the rdfs:subClassOf relationship states and instances of a subclass will also be instances of the superclass. There are no interpretations where this does not hold. Class Membership Another possibility is when :y is a member of both :A and :B . : y a : A . : y a : B . Enter fullscreen mode Exit fullscreen mode It would seem reasonable to infer that :y is therefore an instance of :IntersectionAB . However, inferences are only valid if they apply in every possible system, and the Open World Assumption (OWA) must allow for any new consistent statement. There are statements that can be introduced that are both consistent with the existing statements, and inconsistent with inferring :y as a member of :IntersectionAB . To see an example of this, we can introduce a two new classes, called :C and :D , are the complements of each other. This means that anything that is a member of :C is not a member of :D , and vice versa. We can also make :IntersectionAB a subclass of :C : : IntersectionAB rdfs: subClassOf : A, : B, : C . : C owl: complementOf : D . Enter fullscreen mode Exit fullscreen mode If :y becomes an instance of :D then if cannot be a part of the intersection, since it cannot be an instance of :C . : IntersectionAB rdfs: subClassOf : A, : B, : C . : C owl: complementOf : D . : y a : A, : B, : D . Enter fullscreen mode Exit fullscreen mode Regardless of how contrived the example may be, the fact that any such example exists indicates that the inference may not be made. OWL Intersections The problem with inferring membership in an intersection above is that the intersection is open , meaning that new classes can be added to the intersection, and those classes can preclude an instance of the other classes from becoming a member. OWL addresses this by defining an closed intersection using an RDF Collection . This uses a linked list structure that does not allow for extra members. Redefining :IntersectionAB we can express this in TTL as: : IntersectionAB owl: intersectionOf ( : A : B ) . Enter fullscreen mode Exit fullscreen mode This looks short and simple, but expands into a longer set of triples: : IntersectionAB owl: intersectionOf _: b1 . _: b1 rdf: first : A . _: b1 rdf: rest _: b2 . _: b2 rdf: first : B . _: b2 rdf: rest rdf: nil . Enter fullscreen mode Exit fullscreen mode RDF defines collections to have a specific structure with each node in the list having a single rdf:first and rdf:rest connection, terminating in the rdf:nil node. This means that it is not a valid construct to include any more elements in the collection. As a consequence, if there is an element :y which is an instance of both :A and :B , then it is not possible to add in triples that make :y a member of something that is excluded from the intersection. Therefore, it is valid to infer that :y is in the intersection: : y a : IntersectionAB . Enter fullscreen mode Exit fullscreen mode This is described in the OWL semantics, and demonstrated in the OWL 2 RL profile in the rule cls-int1 found in table 6. This rule states: IF T(?c, owl:intersectionOf, ?x) LIST[?x, ?c1, ..., ?cn] T(?y, rdf:type, ?c1) T(?y, rdf:type, ?c2) ... T(?y, rdf:type, ?cn) Enter fullscreen mode Exit fullscreen mode THEN T(?y, rdf:type, ?c) Enter fullscreen mode Exit fullscreen mode In English it says: If ?c is an intersection described by ?x and ?x is a list containing ?c1 through to ?cn and ?y is an instance of every element in that list Then ?y is an instance of the intersection ?c In Practice Unfortunately, this is tricky to describe in SPARQL. It is easy to check if a value is an instance of one or more members of a list, but how can you check if it is a member of every member of the list? Let's start with some example data, and try to perform the entailment on it. First of all, we can define the intersection of 3 classes: :A , :B and :C . Then we'll describe 3 objects: :m , :n , and :o . The :m object will be an instance of all 3 classes The :n object will be an instance of 2 of the 3 classes The :o object will not be an instance of any of the classes We should be able to find that :m is a member of the intersection, while :n and :o are not. : IntABC owl: intersectionOf ( : A : B : C ). : m a : A, : B, : C . : n a : A, : C . : o a : D . Enter fullscreen mode Exit fullscreen mode Let's start with finding a value ?y which is a member of the intersection class ?c : select distinct ?y where { ?c owl : intersectionOf ?x . ?x rdf : rest */ rdf : first ?cn . ?y a ?cn } Enter fullscreen mode Exit fullscreen mode This returns :m and :n , since they are both instances of classes in the intersection. Now we need to remove values of ?x which don't match every class in the intersection. To do that, start with finding those that don't match everything in the intersection. This can be found by considering each element in the collection (call it ?d ) and pairing it with every other element in the collection (call these ?d2 ). We can then look for the instances of ?d : select distinct ?y ?d ?2 where { ?c owl : intersectionOf ?x . ?x rdf : rest */ rdf : first ?d . ?x rdf : rest */ rdf : first ?d2 . FILTER ( ?d ! = ?d2 ) ?y a ?d } Enter fullscreen mode Exit fullscreen mode This returns every class paired with every other class, but only for instances of the first class: ?y ?d ?d2 :m :C :A :m :C :B :m :A :C :m :A :B :m :B :A :m :B :C :n :C :A :n :C :B :n :A :C :n :A :B Note how :n does not include a ?d equal to :B , but it does have ?d2 set to each value. If we remove cases where ?y is set to the second value, then everything will be removed for ?y = :m , since: when ?y is :m , and :m is an instance of :A , then ?y is also an instance of :B and :C when ?y is :m , and :m is an instance of :B , then ?y is also an instance of :A and :C . when ?y is :m , and :m is an instance of :C , then ?y is also an instance of :A and :B However, when ?y is :n not everything is cancelled: when ?y is :n , and :n is an instance of :A , then ?y is and instance of :C , and that gets removed, but :n is not an instance of :B . when ?y is :n , and :n is an instance of :C , then ?y is an instance of :A , and that gets removed, but :n is not an instance of :B . The query to express this is: select distinct ?y ?d ?d2 where { ?c owl : intersectionOf ?x . ?x rdf : rest */ rdf : first ?d . ?x rdf : rest */ rdf : first ?d2 FILTER ( ?d ! = ?d2 ) ?y a ?d MINUS { ?y a ?d2 }} Enter fullscreen mode Exit fullscreen mode ?y ?d ?d2 :n :C :B :n :A :B Now that we've found the values of ?y that we don't want, they can be removed from the original query: select distinct ?y where { ?c owl : intersectionOf ?x . ?x rdf : rest */ rdf : first ?cn . ?y a ?cn MINUS { ?x rdf : rest */ rdf : first ?d . ?x rdf : rest */ rdf : first ?d2 . FILTER ( ?d ! = ?d2 ) ?y a ?d MINUS { ?y a ?d2 } } } Enter fullscreen mode Exit fullscreen mode This gives the single solution of :m ?y :m So the final rule is: insert { ?y a ?c } where { ?c owl : intersectionOf ?x . ?x rdf : rest */ rdf : first ?cn . ?y a ?cn MINUS { ?x rdf : rest */ rdf : first ?d . ?x rdf : rest */ rdf : first ?d2 . FILTER ( ?d ! = ?d2 ) ?y a ?d MINUS { ?y a ?d2 } } } Enter fullscreen mode Exit fullscreen mode NOTE: This query is for demonstration only. These operations are implemented doubly nested loops, which will not scale at all. It works for small ontologies, but if you try it on something like SNOMED then you will discover that the database will process for over a week. Non-standard SPARQL operations can do this much more efficiently. Final Comment This post was to introduce people to some of the more detailed elements of OWL's representation of Description Logic, explained Valid models are ones in which all interpretations will be true, and how entailment can be made for Consistent statements that lead to correct models for every possible interpretation. The examples at the end demonstrated how entailment can be limited in the open structures of RDFS, but is more capable for the closed structures described in OWL, always remembering that the model itself always follows the Open World Assumption. The SPARQL rule for owl:intersectionOf was me being clever, even if it's useless in the real world due to the scalability issues. 😊 I've been doing this in the real world with code that is outside of SPARQL, but I ought to be able to do it with SPARQL extensions like stardog:list:member (this could remove one level of loop in the above query, but I think it's possible to do even better). All of this is to provide background for my next blog post, which I ought to be able to start now that I've finished writing this!

Report Abuse inboryn Posted on Jan 12 Kubernetes Namespace Isolation: Why It's Not a Security Feature (And What Actually Is) # kubernetes # devops # webdev If you've been managing Kubernetes clusters for any length of time, you've probably heard it: "Use namespaces for security isolation." It's passed around as conventional wisdom in DevOps circles. But here's the uncomfortable truth—it's a dangerous misconception that's leaving production systems vulnerable. Namespaces are not a security boundary. Let me repeat that: Kubernetes namespaces provide logical separation, not security isolation. Understanding this distinction could be the difference between a compromised cluster and a secure one. The Myth: Namespaces as Security Boundaries Most engineers believe that namespaces create security barriers between workloads. Different teams get their own namespace, applications are isolated, problems in one namespace won't affect another. But here's the problem: Workloads in different namespaces can communicate with each other freely by default. An attacker who gains access to any pod can send traffic to pods in other namespaces using simple DNS: service.namespace.svc.cluster.local. Why Namespaces Don't Work as Security Boundaries No Network Isolation by Default Without Network Policies, all pods can talk to all other pods, regardless of namespace. A compromised pod can communicate with the database in another namespace. This is the default behavior—a security nightmare if you're relying on namespaces for isolation. Shared API Server Access Every pod has access to the Kubernetes API server. If a pod is compromised with overly permissive RBAC rules, an attacker can enumerate and access resources across namespaces. Shared Kernel All pods on a node share the same Linux kernel. Without Pod Security Standards, a container breakout could give access to the entire node—all namespaces included. Shared etcd A single compromise could expose all cluster data across all namespaces. What Actually Provides Security in Kubernetes If namespaces aren't the answer, what is? Here's the real security stack you need: Network Policies (Non-Negotiable) Network Policies control traffic between pods. This is your primary defense. Always implement network policies for production workloads. RBAC (Role-Based Access Control) RBAC controls what identities can do with the Kubernetes API. Follow the principle of least privilege: workloads should have minimum permissions needed. Pod Security Standards Pod Security Standards enforce security constraints: Prevent privileged containers Block root execution Restrict capabilities Enforce read-only root filesystems Secrets Management Don't store secrets in configmaps. Use dedicated secret management like HashiCorp Vault, AWS Secrets Manager, or Sealed Secrets. Network Encryption Enable TLS for inter-pod communication Encrypt etcd at rest Use TLS for API server communication Container Image Security Use minimal base images Scan for vulnerabilities Run as non-root The Bottom Line Namespaces are a convenient organizational tool. They help you group workloads and manage resources. But security? That's something else entirely. If you're using namespaces as your security boundary, treat this as urgent. Start implementing Network Policies today. Audit your RBAC rules. Segregate sensitive workloads. Enforce Pod Security Standards. Your production environment depends on it.

Report Abuse Sophie Lane Posted on Dec 24, 2025 • Originally published at keploy.io A Complete Guide To Ci Testing: Benefits, Tools & Workflow # testing # ci Imagine pushing a new feature to production, only to discover that it crippled half your APIs, pushed other teams into delays, and launched a series of frantic bug repairs in the middle of the night. For most dev teams, this is not a describe-a-scenario but a reality. With increasingly intricate apps and quickening release rhythms, making sure each code change integrates just right is a vital need. That’s where CI testing enters the picture. Automatic validation of each commit and integration, a safety net in all respects, preserves your codebase in a sound state and lets you make deployments with confidence in your apps. In this blog, we’ll explore everything from the mechanics and types of CI tests to best practices and real-world strategies, showing how CI testing can transform chaotic integration processes into a seamless, reliable workflow. What is CI Testing? Continuous Integration Testing (CI) refers to the automatic building and testing of software application source code every time the application is merged into a common repository. Unlike the traditional way of doing manual/infrequent testing, which means that by the time your code changes are manually tested, it could have already accumulated a number of integration issues. Therefore, through CI, you can get immediate confirmation that your code changes were tested as part of continuous integration so as to minimize these types of integration problems. CI Testing provides an immediate safety net for code changes in order to allow for the quick identification of defects as a result of automated tests being run on every code commit to the shared repository. Key points regarding CI Testing: • Automated tests will be executed for each commit made to the shared repository • Integration issues can be identified at an early stage in order to prevent you from going into ‘Integration Hell.’ • CI Testing is one of the major components of the CI/CD pipeline. • Improved collaboration between development and QA teams, as quick feedback can be provided. Key Components of CI Testing CI Testing goes beyond just running tests automatically. Several key components of CI Testing allow it to be effective: Automate First – Because CI Testing requires that many tests are built and run frequently, manual testing is not an efficient way to validate software; instead, CI Testing uses automated unit, integration, and API test scripts. Frequent Commits – Developers committed smaller incremental changes on a consistent basis, allowing quick identification of problems in the codebase after committing code. Immediate Feedback – If any tests fail, developers receive notification immediately so they can address the issue with the freshest knowledge of what they have changed in their code. Consistent Environments – Testing should occur within a production-like environment to prevent issues resulting from “it works on my machine” syndrome. Visibility & Reporting – Each time testing occurs, logs, reports, and metrics about the test are generated and enable tracking of testing progress and the quality of software over time. How CI Testing Works: Step-by-Step Pipeline? Here is the standard process that would occur when CI Testing is done: Code Commit: When a developer makes some updates in code, they push those changes to where everyone else has placed their code. Build Trigger: The CI System automatically starts a construct process when a code is pushed to it. Automated Tests Run: Once that task has begun, the entire system runs Automated Tests, including Integration Tests, API / Contract Tests, and, in some cases, Performance Testing will run. Test Results and Reporting: The CI Tool monitors the outcome of these tests,; therefore, A report of Testing Results is sent to the Developer(s) so that they know whether their code was Successful or Failed. Artifact Storage: These build artefacts, such as Binary code, Packages, or Test Log Files, are preserved for future reference. Next Steps in Pipeline: If all the tests pass, it will then continue on with its CI/CD Pipeline to either Staging or Deployment. All of the above steps ensure that the code is continuously examined and continually reduces the likelihood of causing a regressional error, as well as providing a stable software quality. Types of CI Tests Continuous Integration testing is not a one-size-fits-all approach; each project will have its own set of Continuous Integration tests that may include one or more of the following types of tests: Unit Testing – Allows for testing all actions on a piece of code (unit) separately, outside of the context of the rest of the program. Integration Testing – Helps to determine how well multiple units work together. API/Contract Testing – Ensures the API follows all of the requirements defined in its contract and works properly with any other APIs. Performance/Load Testing – Tests how well a system can handle stress. Regression Testing – Verifies that code changes do not disrupt previously working code. If you have an API-first or a microservices architecture, API/Contract Testing is crucial for providing confidence that changes to an individual microservice do not adversely affect other parts of your application. CI Testing for API-First & Microservices Projects CI Testing for microservices and API-first is a common architecture trend in today’s software applications and therefore has unique requirements in terms of CI Testing. Here are some of the important aspects of CI Testing for microservices/API first projects: Testing Isolation: Each microservice should be tested independently before being integrated with other services. Mock Services: Mocking of external services ensures the repeatability of CI Test regardless of the availability of the service. Contract Validation: Contract Testing for APIs must ensure the uncovering and prevention of any breaking changes between API’s. Parallel Testing: CI Testing for microservices the architecture allows for the concurrent execution of CI Tests, resulting in the quickest delivery of Continuous Feedback. Observability: The Logs and Metrics from API Testing provide the ability to provide quick feedback as to which microservice failed. By focusing on these important areas of CI Testing, you will be able to continue to build robust, complex, and large systems while deploying and modifying them more often than ever before. Benefits of CI Testing Integrating Continuous Integration testing into software development has several benefits for both the development team and ultimately users of the software through increased efficiency and improvements to the quality of software. Some of the key benefits include: Early Bug Detection: Getting an early start on identifying defects within code during the course of development (to get an overall feel/understanding of the functionality of the software) allows an organization to eliminate potential issues down the road and unnecessary costs. Faster Feedback Loops: Receiving prompt alerts about failing tests provides a mechanism for individuals to quickly identify and address issues. These quick responses not only minimize idle time but also enable teams to continuously improve their position in providing software to complement an organizational unit’s development cycle through new and improved methods of development. Improved Code Quality: Writing clean, maintainable code requires more frequent use of Continuous Integration (CI) testing. By continuously validating that they have fulfilled all requirements and that the developers have produced acceptable quality. Reduced Risk: Continuous Integration and corresponding CI processes enable teams to maintain an ongoing review of their processes, establish acceptable standards, and determine any areas of improvement to ensure they are producing software at an acceptable standard. Enhanced Collaboration: Incremental changes increase the ability to efficiently address any problems encountered with the current build by allowing for easy identification and resolution of any issues being experienced. Faster Release Cycles: The earlier in the development cycle that problems are identified, the easier it becomes to resolve any issues without major loss of productivity. This allows teams to release features and updates more frequently. Top CI Testing Tools Finding the right unit testing software for CI can mean the difference between efficiency and chaos in your building process. There are many choices available for CI Unit Testing solutions. Therefore, you must choose one that will be compatible with the types of technology your team uses, the projects you are working on, and the tests you need to run. If you have an API-first development model, selecting CI software with automated API testing capabilities will reduce the time you have to spend doing multiple integrations. Here’s a list of some of the most popular CI testing tools, along with their strengths and ideal use cases: | Tool | Strengths | Ideal Use Case | |----------------|---------------------------------------------------------------------------|-----------------------------------------------------------------| | Keploy | Focused on API testing automation, open source, supports contract testing and regression detection | API-first microservices and CI pipelines needing automated API tests | | Jenkins | Highly customizable with a large plugin ecosystem | General-purpose CI/CD for varied tech stacks | | GitHub Actions | Easy integration with GitHub and generous free tiers | GitHub repositories and cloud-native pipelines | | GitLab CI | Built-in CI/CD with strong automation capabilities | End-to-end GitLab projects | | CircleCI | Fast, scalable, and supports parallelism | Large-scale projects requiring high-speed builds | | Travis CI | Simple setup and cloud-hosted | Open-source projects | Enter fullscreen mode Exit fullscreen mode Pro Tip: Look for testing tools that integrate well with your current environment and provide valuable insight into the results of your CI tests. A great example of an API testing and validation tool for developers working on projects using an API-first approach is Keploy, which offers many great features for automating API testing and providing input into regression. Best Practices in CI Testing For CI Testing to function properly, teams must adhere to established best practices in order to derive maximum benefit. Those who do will have dependable pipelines, be able to identify problematic code early in the development cycle, and be able to get their software delivered faster. Here are some important examples of CI Testing Best Practices: Automate all you can: Unit, integration, API and performance testing will provide more consistent and dependable results than any manual process could. Commit often: Smaller, incremental code changes will reduce the chances of code merge conflicts as well as allow developers to pinpoint code problems more easily. Keep tests running quickly: If your tests take a long time to run, this affects how quickly you receive feedback, thereby reducing your ability to keep developing code quickly; therefore, keep your test running speed as fast as possible. Keep your tests reliable: Flaky tests or tests that do not produce consistent results will erode developer confidence in CI pipelines, and as such, it is essential that CI Testing is stable. Use identical test environments: Using containerization technology, either using Docker or VM (Virtual Machines), to test on will produce test results that are more similar to production service test results, eliminating the dreaded “It worked on my computer” issue. Measure your CI metrics: Measuring your CI metrics over time will allow you to continuously improve both the quality of your code and the speed with which your CI Pipelines function. Common Challenges in CI Testing There are also CI Testing issues that all teams that are using CI, need to be prepared for even if they are doing it properly. By understanding these common issues, teams can better create an efficient, effective and scalable pipeline for Continuous Integration (CI). Flaky Tests: Intermittently failing tests can mislead teams in addition to causing wasted time debugging these intermittent failures. Slow Pipelines: Large test suites or inefficiently created tests cause teams to delay receiving feedback about the ‘Success of the Integration’ and therefore slows down their Release Cycle. Environment Mismatches: Environmental Differences between Development, Staging and Production can result in Unexpected Build Failures. Insufficient Coverage: Lack of tests to cover critical scenarios allows for regressions to be moved into Production. Scaling CI: CI must rely on the Orchestration of tests, Selective Execution of Testing and Parallel Execution of Testing to avoid Losing Efficiency when a Project Grows Larger. For Teams to surmount the aforementioned challenges, they should give priority to stabilizing their flaky tests, optimizing testing speed through their test suites, maintaining environmental consistency, providing for adequate coverage, and performing duplicate or selective tests through parallel Testing. To help simplify CI scalability while improving CI reliability, use tools such as Keploy for automated API testing and regression Testing. How Keploy Enhances CI Testing for API-First Projects? Managing CI testing for teams with an API-first or microservice architecture can be extremely difficult to manage, as there are so many sub-components that must be integrated together and also tested. With Keploy, this process is streamlined with automation, which makes it possible to automate CI Testing of APIs along with Regression Detection and Reporting. Below are some of the key benefits of using Keploy to improve CI Testing capabilities: Automated Generation of API Tests – During development, Keploy records actual API calls being made and automatically generates tests that can then be run in the CI pipeline, thus reducing the amount of time spent on creating tests manually and ensuring adequate test coverage. Regression Detection – Each time a developer commits code, the code is validated against the existing API’s actual functionality, which will help to identify errors in the newly committed code or possible Regressions before deploying changes to production. Optimized Test Orchestration – By optimally orchestrating test executions, Keploy allows users to run tests in parallel, prioritize tests for mission-critical workflows, and decrease test execution time without sacrificing test coverage. Reports – Keploy provides comprehensive information and metrics including Pass/Fail, Test Logs, and API metrics so a team’s members can quickly identify issues that arise during CI Testing and resolve them. Easy Integration with Common CI/CD Applications – Because Keploy connects seamlessly with all major CI/CD Applications such as Jenkins, GitHub Actions, and GitLab CI, it is extremely easy to integrate Keploy into a team’s existing workflow. By utilizing Keploy, teams can be confident that their most complex API Microservices will have stability, they will catch regressions before they become a production issue, and they will be able to run their CI Pipelines with minimal manual intervention. Conclusion The foundation of modern software development lies within Continuous Integration Testing. CI testing does not exist just to support test execution; it aids in adding quality at each code change and helps find issues prior to becoming larger problems, thus allowing teams to become quicker and more confident in their development activities. With the benefits seen through implementing the best strategies and tools such as Keploy, teams have the ability to overcome challenges associated with the complexity of working with APIs and Microservices; in addition, all releases will create greater/meaningful value. In summary, Continuous Integration Testing’s objective goes beyond simple automation; it allows for the development of better software, the use of strategic and intelligent continuous integration testing. FAQs 1. How to handle regression testing in CI? When creating a regression test suite for Continuous Integration (CI) access, you should automate your testing process and have your automated tests execute when there is a code commit. You may benefit from executing selective tests or providing test execution priority to have quick feedback on any regression issues. 2. How does CI testing fit into the DevOps lifecycle? Continuous Integration (CI) Testing is part of the “Development” portion of the DevOps Lifecycle. CI Testing helps ensure that the code being written and tested is of acceptable quality before deployment and is integrated into the CI/CD Pipeline so that CI Testing is associated with the processes required for Continuous Delivery of software. 3. How do I choose the right CI tool for my project? There are a number of factors to consider when selecting a Continuous Integration (CI) tool for your project. These include the size of your project, the stack used for the project, the types of tests you will run, your integration needs, as well as your budget. 4. How to integrate API tests into a CI/CD pipeline? To integrate API Tests into a CI/CD Pipeline, you should trigger the automated tests (API tests) after each commit, log all API interactions when they were made, replay the same API calls from your logging, and display those results as part of your CI/CD report.

Report Abuse Esimit Karlgusta Posted on Jan 13 How to Handle Stripe and Paystack Webhooks in Next.js (The App Router Way) # api # nextjs # security # tutorial The #1 reason developers struggle with SaaS payments is Webhook Signature Verification. You set everything up, the test payment goes through, but your server returns a 400 Bad Request or a Signature Verification Failed error. In the Next.js App Router, the problem usually stems from how the request body is parsed. Stripe and Paystack require the raw request body to verify the signature, but Next.js often tries to be helpful by parsing it as JSON before you can get to it. Here is the "Golden Pattern" for handling this in 2026. 1. The Route Handler Setup Create a file at app/api/webhooks/route.ts . You must export a config object (if using older versions) or use the req.text() method in the App Router to prevent automatic parsing. import { NextResponse } from " next/server " ; import crypto from " crypto " ; export async function POST ( req : Request ) { // 1. Get the raw body as text const body = await req . text (); // 2. Grab the signature from headers const signature = req . headers . get ( " x-paystack-signature " ) || req . headers . get ( " stripe-signature " ); if ( ! signature ) { return NextResponse . json ({ error : " No signature " }, { status : 400 }); } // 3. Verify the signature (Example for Paystack) const hash = crypto . createHmac ( " sha512 " , process . env . PAYSTACK_SECRET_KEY ! ) . update ( body ) . digest ( " hex " ); if ( hash !== signature ) { return NextResponse . json ({ error : " Invalid signature " }, { status : 401 }); } // 4. Now parse the body and handle the event const event = JSON . parse ( body ); if ( event . event === " charge.success " ) { // Handle successful payment in your database console . log ( " Payment successful for: " , event . data . customer . email ); } return NextResponse . json ({ received : true }, { status : 200 }); } Enter fullscreen mode Exit fullscreen mode 2. The Middleware Trap If you have global middleware protecting your routes, ensure your webhook path is excluded. Otherwise, the payment provider will hit your login page instead of your API. 3. Why this matters for your SaaS If your webhooks fail, your users won't get their "Pro" access, and your churn will skyrocket. Handling this correctly is the difference between a side project and a real business. I have spent a lot of time documenting these "Gotchas" while building my MERN stack projects. If you want to see a full implementation of this including Stripe, Paystack, and database logic, check out my deep dive here: How to add Stripe or Paystack payments to your SaaS . Digging Deeper If you are tired of debugging the same boilerplate over and over, you might find my SassyPack overview helpful. I built it specifically to solve these "Day 1" technical headaches for other founders. Happy coding!

Depending on your jurisdiction, the specific Stripe entity accountable for your Personal Data might vary.

Fraud Prevention and Security . We collect and use Personal Data to help us identify and manage activities that could be fraudulent or harmful across our Services, enable our fraud detection Business Services, and secure our Services and transactions against unauthorized access, use, alteration or misappropriation of Personal Data, information, and funds. As part of the fraud prevention, detection, security monitoring, and compliance efforts for Stripe and its Business Users, we collect information from publicly available sources, third parties (such as credit bureaus), and via the Services we offer. In some instances, we may also collect information about you directly from you, or from our Business Users, Financial Partners, and other third parties for the same purposes. Furthermore, to protect our Services, we may receive details such as IP addresses and other identifying data about potential security threats from third parties. Learn More . Such information helps us verify identities, conduct credit checks where lawfully permitted, and prevent fraud. Additionally, we might use technology to evaluate the potential risk of fraud associated with individuals seeking to procure our Business Services or arising from attempted transactions by an End Customer or End User with our Business Users or Financial Partners. Compliance with Legal Obligations . We use Personal Data to meet our contractual and legal obligations related to anti-money laundering, Know-Your-Customer ("KYC") laws, anti-terrorism activities, safeguarding vulnerable customers, export control, and prohibition of doing business with restricted persons or in certain business fields, among other legal obligations. For example, we may monitor transaction patterns and other online signals and use those insights to identify fraud, money laundering, and other harmful activity that could affect Stripe, our Financial Partners, End Users, Business Users and others. Learn More . Safety, security, and compliance for our Services are key priorities for us, and collecting and using Personal Data is crucial to this effort. Minors . Our Services are not directed to children under the age of 13, and we request that they do not provide Personal Data to seek Services directly from Stripe. In certain jurisdictions, we may impose higher age limits as required by applicable law. c. Sharing of Personal Data. Besides the sharing of Personal Data described above, we share Personal Data in the ways listed below: Stripe Affiliates . We share Personal Data with other Stripe-affiliated entities for purposes identified in this Policy. Service Providers or Processors . In order to provide, communicate, market, analyze, and advertise our Services, we depend on service providers. These providers offer critical services such as providing cloud infrastructure, conducting analytics for the assessment of the speed, accuracy, and/or security of our Services, verifying identities, identifying potentially harmful activity, and providing customer service and audit functions. We authorize these service providers to use or disclose the Personal Data we make available to them to perform services on our behalf and to comply with relevant legal obligations. We require these service providers to contractually commit to security and confidentiality obligations for the Personal Data they process on our behalf. The majority of our service providers are based in the European Union, the United States of America, and India. Learn More . Financial Partners . We share Personal Data with certain Financial Partners to provide Services to Business Users and offer certain Services in conjunction with these Financial Partners. For instance, we may share certain Personal Data, such as payment processing volume, loan repayment data, and Representative contact information, with institutional investors and lenders who purchase loan receivables or provide financing related to Stripe Capital. Learn More . Others with Consent . In some situations, we may not offer a service, but instead refer you to others (like professional service firms that we partner with to deliver the Atlas Service). In these instances, we will disclose the identity of the third party and the information to be shared with them, and seek your consent to share the information. Corporate Transactions . If we enter or intend to enter a transaction that modifies the structure of our business, such as a reorganization, merger, sale, joint venture, assignment, transfer, change of control, or other disposition of all or part of our business, assets, or stock, we may share Personal Data with third parties in connection with such transaction. Any other entity that buys us or part of our business will have the right to continue to use your Personal Data, subject to the terms of this Policy. Compliance and Harm Prevention . We share Personal Data when we believe it is necessary to comply with applicable law; to abide by rules imposed by Financial Partners in connection with the use of their payment method; to enforce our contractual rights; to secure and protect the Services, rights, privacy, safety, and property of Stripe, you, and others, including against malicious or fraudulent activity; and to respond to valid legal requests from courts, law enforcement agencies, regulatory agencies, and other public and government authorities, which may include authorities outside your country of residence. 3. Legal bases for processing Personal Data For purposes of the General Data Protection Regulation (GDPR) and other applicable data protection laws, we rely on a number of legal bases to process your Personal Data. Learn More . For some jurisdictions, there may be additional legal bases, which are outlined in the Jurisdiction-Specific Provisions section below. a. Contractual and Pre-Contractual Business Relationships .

Report Abuse Esimit Karlgusta Posted on Jan 13 How to Handle Stripe and Paystack Webhooks in Next.js (The App Router Way) # api # nextjs # security # tutorial The #1 reason developers struggle with SaaS payments is Webhook Signature Verification. You set everything up, the test payment goes through, but your server returns a 400 Bad Request or a Signature Verification Failed error. In the Next.js App Router, the problem usually stems from how the request body is parsed. Stripe and Paystack require the raw request body to verify the signature, but Next.js often tries to be helpful by parsing it as JSON before you can get to it. Here is the "Golden Pattern" for handling this in 2026. 1. The Route Handler Setup Create a file at app/api/webhooks/route.ts . You must export a config object (if using older versions) or use the req.text() method in the App Router to prevent automatic parsing. import { NextResponse } from " next/server " ; import crypto from " crypto " ; export async function POST ( req : Request ) { // 1. Get the raw body as text const body = await req . text (); // 2. Grab the signature from headers const signature = req . headers . get ( " x-paystack-signature " ) || req . headers . get ( " stripe-signature " ); if ( ! signature ) { return NextResponse . json ({ error : " No signature " }, { status : 400 }); } // 3. Verify the signature (Example for Paystack) const hash = crypto . createHmac ( " sha512 " , process . env . PAYSTACK_SECRET_KEY ! ) . update ( body ) . digest ( " hex " ); if ( hash !== signature ) { return NextResponse . json ({ error : " Invalid signature " }, { status : 401 }); } // 4. Now parse the body and handle the event const event = JSON . parse ( body ); if ( event . event === " charge.success " ) { // Handle successful payment in your database console . log ( " Payment successful for: " , event . data . customer . email ); } return NextResponse . json ({ received : true }, { status : 200 }); } Enter fullscreen mode Exit fullscreen mode 2. The Middleware Trap If you have global middleware protecting your routes, ensure your webhook path is excluded. Otherwise, the payment provider will hit your login page instead of your API. 3. Why this matters for your SaaS If your webhooks fail, your users won't get their "Pro" access, and your churn will skyrocket. Handling this correctly is the difference between a side project and a real business. I have spent a lot of time documenting these "Gotchas" while building my MERN stack projects. If you want to see a full implementation of this including Stripe, Paystack, and database logic, check out my deep dive here: How to add Stripe or Paystack payments to your SaaS . Digging Deeper If you are tired of debugging the same boilerplate over and over, you might find my SassyPack overview helpful. I built it specifically to solve these "Day 1" technical headaches for other founders. Happy coding!

Report Abuse Anmol Baranwal Posted on Jan 30, 2024 • Edited on May 16, 2024 😁12 things you didn't know you could do with DEV # howtodevto # tutorial # writing # beginners Exciting things you could do with DEV (2 Part Series) 1 😁12 things you didn't know you could do with DEV 2 😁12 things you didn't know you could do with DEV part 2 As a developer, I'm always looking for those little details because, well, the details matter. We're all part of one big community here on DEV, and in this post, I'm excited to share some unexpected features and tricks that you might not be aware of on this platform. Let me take you through 12 surprising things you can do on DEV, from creating custom buttons to creating your comment templates! Please comment and let me know which point surprised you the most. 1. Filter posts using tags. With the constant intake of posts in our feeds, having some control and filters is essential. One way is to filter posts by using tags. For instance, to view posts with the #discuss tag, simply navigate to dev.to/t/discuss . Likewise, if you want posts with the tag #softwaredevelopment , head over to dev.to/t/softwaredevelopment . As a general rule, you can use this. https://dev.to/t/paste_your_tag_without_spaces Enter fullscreen mode Exit fullscreen mode You can paste the above URL with your tag to see the top posts in that relevant category. You can discover tag moderators responsible for handling that particular tag. In case you're wondering, tag moderators are responsible for maintaining the relevance of the tags with the post. You can check the tags you're following at dev.to/dashboard/following_tags . A comprehensive list of all tags is available at dev.to/tags . 2. Handy resources based on official tags. It might be related to the first one, but it's not true for every tag. Certain tags provide handy official resources, such as documentation for tailwindcss or helpful guides for nextjs . These resources can be valuable, especially if you're new to a particular tag. For instance, the nextjs tag has decent resources :) These "little details" make the DEV platform more user-friendly and informative. 3. RSS Feed. Explaining RSS feed to a 5-year-old: Imagine you have a favorite cartoon show, and every time there's a new episode, your magical TV shows it to you. The RSS feed is like that magic messenger for websites. It tells your computer when there's something new on your favorite website, so you can see it without having to check all the time. It's like a friendly notification that says, "Hey, something interesting happened on the website you like!". It's like having a personalized news feed with content from multiple sources. Check your DEV RSS feed using: dev.to/feed/your_username Check Chrome extension that I use to find RSS Feed URLs. Learn more about how drafts are created from your feed at DEV in this guide . Head to dev.to/settings/extensions to paste your RSS Feed URL and integrate it with your DEV profile. Suppose you have your own blog, and whenever you publish a blog to your website -> dev will fetch that blog as a draft post which you can publish from the dashboard. What is a Canonical URL? Imagine you have a webpage, and there are a few copies or variations of it. (Your personal blog + DEV blog) A canonical URL is like tagging the main one as the boss—the original source. It helps search engines know which version is the most important or preferred, preventing confusion and improving your webpage's search engine ranking. Understanding canonical URLs is crucial when re-publishing content to maintain clarity for search engines. 4. Crazy Badges for Lots of Innovative Things. DEV awards several badges weekly based on the technologies featured in articles. From tech stack badges to quirky ones like the "Beloved Comment" badge, each badge holds its own charm. For example, if you write an article with React and are considered a top author of the week, you will be awarded the React badge. I can't help but share my excitement about some adorable badges I've seen. I know a couple of guys who have this beloved badge. If you know, comment down! Who has this one? LOL! Worth a party. I have this one but didn't win any game 🤣 The Top 7 Author Badge, often regarded as the most prestigious, is my personal favorite. Earning this badge is truly an honor in its own right. I can't list them all; otherwise, people will get angry. LOL! Explore the complete list of badges at dev.to/badges . 5. Software comparisons. Comparing Software is not a new trend. We do it all the time. So, the DEV Team made a list of top posts that the community has created. These are the posts folks have generally continued coming back to over and over again. The list has around 350+ software companies. Must check! dev.to/software-comparisons - software comparisons 6. Adding a caption to your image. In DEV posts, you can add captions to your images that provide context or additional information to complement the image shown. It's an interesting way to navigate within the image. Here's how you can do it. You have to use the <figcaption> tag after the image. For instance, see the image below along with it syntax. GitHub Profile of Anmol Baranwal  <figcaption> GitHub Profile of Anmol-Baranwal </figcaption> Enter fullscreen mode Exit fullscreen mode 7. Subscribe to comments. Typically, as the author of a post, you're automatically subscribed to all comments. This means you'll receive notifications for every comment on that post. However, what's interesting is that you can also subscribe to comments on other posts. I recommend doing this, especially for posts with a #discuss tag, as it exposes you to various perspectives, leading to valuable learning experiences in the end. Notifications of top-level comments is a handy one. 8. Embed & Line break. Most of the people would already know this. But for those who don't, you can embed any video so that you can play the video rather than pasting a link. It allows viewers to watch the video directly without visiting another site. {% embed paste_url_here %} Enter fullscreen mode Exit fullscreen mode For example, embedding my DEV profile will look like this. Anmol Baranwal Follow Technical writer (1.5M+ reads) • Open Source developer Everything about me at "https://anmolbaranwal.com" Email for collab Some might not be aware of creating line breaks using &nbsp; . This simple technique improves the readability of your posts. For example, This first sentence can be separated from the next content using &nbsp; . The second sentence is separated by a line break. 9. A call-to-action button. This is the coolest! Did you know you can make a personalized button with a description? So exciting! It's a handy way to grab attention and enhance engagement, and it's super easy to implement. For instance, let's create a CTA for my GitHub profile: 🚀 Visit My GitHub Profile You can use the below syntax for creating that button: {% cta https://github.com/Anmol-Baranwal %} 🚀 Visit My GitHub Profile {% endcta %} Enter fullscreen mode Exit fullscreen mode This personalized touch can add a whole new dimension to your posts. The syntax uses liquid tags created by Shopify. 10. Complete Editor Guide. Here's a hidden gem that even top authors might not be aware of. The DEV team has made a comprehensive editor guide covering almost every aspect of using the editor. It's a one-stop resource for answering questions like: How to add a caption to your image Supported URL embeds How to add comments (author notes) which won't show up in the content Markdown basics + recommended cover image size (1000 * 420) They have even covered accessibility and much more. Read the complete guide at dev.to/p/editor_guide . Big kudos to the DEV team for creating such a handy guide! Do follow the official DEV team and join the fun :) The DEV Team Follow The team behind this very platform. 😄 11. Comment Templates. Another nifty feature that DEV offers is the ability to save comment templates. Whether it's for introducing yourself or sharing your social media URLs, these templates can save you time and add consistency to your interactions. It may be small, but it packs a punch! It closely mirrors a functionality commonly found on GitHub. Let's see how it works. To set up your comment templates, visit dev.to/settings/response-templates You can easily add new templates with short titles for quick reference. When you're in the comments section of a post, click the three dots on the bottom right -> then the bookmark symbol. You'll find a list of templates that you can directly use. Trusted users even get a predefined list of templates for extra ease. 12. Podcasts? Videos? And the power of Hidden tags. Did you know you could upload videos for your posts on DEV? You can find the option to upload the video in the left bottom corner at dev.to/dashboard It's a fantastic way to improve your post. Discover these video posts at dev.to/videos . DEV also hosts a section dedicated to podcasts. You can even submit your own podcast for review and explore various others at dev.to/pod . Hidden Tags for Personalized Feeds Hidden tags are a way to provide you with more control over what you see and a means of hiding content from your feed that you don't want to see. You can hide tags over on the tags page - use the search to find a specific tag you want to hide You can also hide tags over on the "Following tags" section of your dashboard - press the three dots to access the hide option You can find hidden tags at dev.to/dashboard/hidden_tags . You can see which tags you've hidden on your dashboard and unhide them This feature ensures a more personalized and enjoyable browsing experience on DEV. I'm not covering APIs since it would make the post very long. However, if you're interested, you can explore more about Forem APIs . Bonus I know, I know! I promised 12 things, but here's a little extra on "How you can earn money whenever someone reads your blog!" Explore the concept of Web Monetization in this insightful blog post . It's an awesome guide that explains everything you need to know. You can also read more on how to become a DEV Mod and collaborate with fellow community members. I don't know about you, but I'm extra excited, and there might be more treasures that the DEV Team is hiding. LOL! I hope you learned something new today. I love the DEV community as it is an excellent place for encountering great content of all kinds: lively discussion posts, in-depth tutorials, library updates, career advice, and a lot more.

I believe people need to have fun, go deep, and find these small details about DEV. Telling you the truth, I began my writing journey on DEV and never wrote on Hashnode or Medium before DEV. I'm not a fan of Medium because of the paywall, and Hashnode seems challenging for beginners. I only want people to read my content and enjoy it. See you later. Hope you like it!

Location Scotland Education Something something cybernetics Pronouns They/them Work General-purpose software person Joined Aug 29, 2017 • Jan 31 '24 Dropdown menu Copy link Hide You mean like a signature on an email or an old-style forum? I think it's probably not a good idea; people are generally negative towards signatures because in those old enviroments they tended to fill up your feed with repetetive fluff. That shouldn't happen on DEV since you only read one post at a time and the feed only contains a snippet, but generally speaking I think signatures have baggage . They might also feel like too much self-promotion, especially if you see the same ones again and again. There's nothing stopping you pasting the same content into multiple posts yourself, of course, but I think they'd mostly get used for "follow me on $platform" and "buy me an lemonade shandy" links, and we already have the ability to set social media links against your profile. Perhaps a solution which covers that would be a new feature to allow users to set which links/buttons appear in the little popover you see when you hover over their name?

You can use a slash (/) to create a table with different rows and columns, and then you can customize it. In DEV, I have to rewrite the structure, which can be frustrating. So, having some small snippets could be useful. For instance, the snippet to create a line break within bullet points .

I understand the rational : it’s mostly used for linking to other social media’s but also suggesting the user to comment/like, etc. I have been copy/pasting the text and it looks like a lot of bloggers here do it too. So maybe it’s worth adding ? If not, the popover would be great indeed !!!
