Report Abuse Farhad Hossain Posted on Jan 13 Mouse Events in JavaScript: Why Your UI Flickers (and How to Fix It Properly) # frontend # javascript # ui Hover interactions feel simple—until they quietly break your UI. Recently, while building a data table, I ran into a strange issue. Each row had an “Actions” column that appears when you hover over the row. It worked fine most of the time, but sometimes—especially when moving the mouse slowly or crossing row borders—the UI flickered. In some cases, two rows even showed actions at once. At first glance, it looked like a CSS or rendering bug. It wasn’t. It was a mouse event model problem . That experience led me to a deeper realization: Not all mouse events represent user intent. Some represent DOM mechanics—and confusing the two leads to fragile UI. Let’s unpack that. The Two Families of Mouse Hover Events JavaScript gives us two sets of hover events: Event Bubbles Fires when mouseover Yes Mouse enters an element or any of its children mouseout Yes Mouse leaves an element or any of its children mouseenter No Mouse enters the element itself mouseleave No Mouse leaves the element itself This difference seems subtle, but it’s one of the most important distinctions in UI engineering. Why mouseover Is Dangerous for UI State Consider this table row: <tr> <td>Name</td> <td class="actions"> <button>Edit</button> <button>Delete</button> </td> </tr> Enter fullscreen mode Exit fullscreen mode From a user’s perspective, they are still “hovering the row” when they move between the buttons. But from the browser’s perspective, something very different is happening: <tr> → <td> → <button> Each move fires new mouseover and mouseout events as the cursor travels through child elements. That means: Moving from one button to another fires mouseout on the first Which bubbles up And can look like the mouse “left the row” Your UI hears: “The row is no longer hovered.” The user never left. This mismatch between DOM movement and human intent is the root cause of flicker. How My Table Broke In my case: Each table row showed action buttons on hover Borders existed between rows When the mouse crossed that 1px border, it briefly exited one row before entering the next This triggered: mouseout → hide actions mouseover → show actions again Sometimes the timing was fast enough that: Two rows appeared active Or the UI flickered Nothing was “wrong” with the layout. The event model was simply lying about what the user was doing. Why mouseenter Solves This mouseenter and mouseleave behave very differently. They do not bubble. They only fire when the pointer actually enters or leaves the element itself—not its children. So this movement: <tr> → <td> → <button> Triggers: mouseenter(tr) Once. No false exits. No flicker. No state confusion. This makes them ideal for: Table rows Dropdown menus Tooltips Hover cards Any UI that should remain active while the cursor is inside In other words: mouseenter represents user intent mouseover represents DOM traversal When You Should Use Each Use mouseenter / mouseleave when: You are toggling UI state based on hover Child elements should not interrupt the hover Stability matters Examples: Row actions Navigation menus Profile cards Tooltips Use mouseover / mouseout when: You actually care about which child was entered. Examples: Image maps Per-icon tooltips Custom hover effects on individual elements Here, bubbling is useful. React Makes This More Subtle In React, onMouseOver and onMouseOut are wrapped in a synthetic event system. That adds another layer of propagation and re-rendering, which can amplify flicker and race conditions. This is why tables, dropdowns, and hover-driven UIs are often harder to get right than they look. A Practical Rule of Thumb If you are using mouseover to control UI visibility, you are probably building something fragile. Most hover-based UI should be built with: mouseenter mouseleave Because users don’t hover DOM nodes. They hover things . Final Thoughts That small flicker in my table wasn’t a bug—it was a reminder of how deep the browser’s event model really is. The best UI engineers don’t just write logic that works. They write logic that matches how humans actually interact with the screen. And sometimes, the difference between a glitchy UI and a rock-solid one is just a single event name.

If you want to know how to use it, you can refer to - [Slides](https://speakerdeck.com/techverse_2022/vald-oss-ann-nearest-neighbor-dense-vector-search-engine-introduction-and-case-studies). - Session: https://tech-verse.me/en/sessions/172 ## Our Automation Tool for Migrating 1,800 MySQL Instances in Only Six Months <iframe frameborder="0" src="https://speakerdeck.com/player/52b80ea6286f4fa9ad587699c3324731" title="Our Automation Tool for Migrating 1,800 MySQL Instances in Only Six Months" allowfullscreen="true" mozallowfullscreen="true" webkitallowfullscreen="true" style="border: 0px; background: padding-box padding-box rgba(0, 0, 0, 0.1); margin: 0px; padding: 0px; border-radius: 6px; box-shadow: rgba(0, 0, 0, 0.2) 0px 5px 40px; width: 560px; height: 314px;" data-ratio="1.78343949044586"></iframe> Have you upgraded MySQL before? Due to the expansion of LINE's business, the entire enterprise has more than 6000 MySQL Instances. In order to upgrade the version of MySQL 5.6 (which has stopped maintenance in 2021/02), it will be an incalculable cost. <iframe frameborder="0" src="https://speakerdeck.com/player/52b80ea6286f4fa9ad587699c3324731?slide=15" title="Our Automation Tool for Migrating 1,800 MySQL Instances in Only Six Months" allowfullscreen="true" mozallowfullscreen="true" webkitallowfullscreen="true" style="border: 0px; background: padding-box padding-box rgba(0, 0, 0, 0.1); margin: 0px; padding: 0px; border-radius: 6px; box-shadow: rgba(0, 0, 0, 0.2) 0px 5px 40px; width: 560px; height: 314px;" data-ratio="1.78343949044586"></iframe> Generally speaking, the MySQL update process can be divided into: - Create New MySQL Instance - Add User ACL - Set MySQL Variable - Export/Import Data - Start Replication - Inspect Query Performace - Switch to new MySQL. (In midnight?) - Shutdown old MySQL This kind of work is actually quite time-consuming.

Report Abuse eachampagne Posted on Jan 12 Websockets with Socket.IO # javascript # node # webdev # networking This post contains a flashing gif. HTTP requests have taken me pretty far, but I’m starting to run into their limits. How do I tell a client that the server updated at midnight, and it needs to fetch the newest data? How do I notify one user when another user makes a post? In short, how do I get information to the client without it initiating the request? Websockets One possible solution is to use websockets , which establish a persistent connection between the client and server. This will allow us to send data to the client when we want to, without waiting for the client’s next request. Websockets have their own protocol (though the connection is initiated with HTTP requests) and are language-agnostic. We could, if we wanted, implement a websocket client and its corresponding server from scratch or with Deno … or we could use one of the libraries that’s already done the hard work for us. I’ve used Socket.IO in a previous project, so we’ll go with that. I enjoyed working with it before, and it even has the advantage of a fallback in case the websocket fails. Colorsocket For immediate visual feedback, we’ll make a small demo where any one client can affect the colors displayed on all. Each client on the /color endpoint has a slider to control one primary color, plus a button to invert all the other /color clients. (The server assigns a color in order to each client when the client connects, so you just have to refresh a few times until you get all three colors. I did make sure duplicate colors would work in sync, however.) The /admin user can turn primary colors on or off. Here’s the app in action: The clients aren’t all constantly making requests to the server. How do they know to update? Establishing Connections When each client runs its <script> , it creates a new socket, which opens a connection to the server. // color.html const socket = io ( ' /color ' ); // we’ll come back to the argument Enter fullscreen mode Exit fullscreen mode The script then assigns handlers on the new socket for the various events we expect to receive from the server: // color.html socket . on ( ' assign-color ' , ( color , colorSettings , activeSettings ) => { document . getElementById ( ' color-name ' ). innerText = color ; controllingColor = color ; currentBackground = colorSettings ; active = activeSettings ; colorSlider . disabled = ! active [ controllingColor ]; document . getElementById ( ' active ' ). innerText = active [ controllingColor ] ? ' active ' : ' inactive ' ; colorSlider . value = colorSettings [ controllingColor ]; updateBackground (); }); socket . on ( ' set-color ' , ( color , value ) => { currentBackground [ color ] = value ; if ( controllingColor === color ) { colorSlider . value = value ; } updateBackground (); }); socket . on ( ' invert ' , () => { inverted = ! inverted ; document . getElementById ( ' inverted ' ). innerText = inverted ? '' : ' not ' ; updateBackground (); }); socket . on ( ' toggle-active ' , ( color ) => { active [ color ] = ! active [ color ]; if ( controllingColor === color ) { colorSlider . disabled = ! active [ color ]; } document . getElementById ( ' active ' ). innerText = active [ controllingColor ] ? ' active ' : ' inactive ' ; updateBackground (); }); Enter fullscreen mode Exit fullscreen mode Meanwhile, the server detects the new connection. It assigns the client a color, sends that color and current state of the application to the client, and sets up its own handlers for events received through the socket: // index.js colorNamespace . on ( ' connection ' , ( socket ) => { const color = colors [ colorCount % 3 ]; // pick the next color in the list, then loop colorCount ++ ; socket . emit ( ' assign-color ' , color , colorSettings , activeSettings ); // synchronize the client with the application state socket . data . color = color ; // you can save information to a socket’s data key, but I didn’t end up using this for anything socket . on ( ' set-color ' , ( color , value ) => { colorSettings [ color ] = value ; colorNamespace . emit ( ' set-color ' , color , value ); }); socket . on ( ' invert ' , () => { socket . broadcast . emit ( ' invert ' ); }); }); Enter fullscreen mode Exit fullscreen mode The /admin page follows similar setup. Sending Information to the Client Let’s follow how user interaction on one page changes all the others. When a user on the blue page moves the slider, the slider emits a change event, which is caught by the slider’s event listener: // color.html colorSlider . addEventListener ( ' change ' , ( event ) => { socket . emit ( ' set-color ' , controllingColor , event . target . value ); }); Enter fullscreen mode Exit fullscreen mode That event listener emits a new set-color event with the color and new value. The server receives the client’s set-color , then emits its own to transmit that data to all clients. Each client receives the message and updates its blue value accordingly. Broadcasting to Other Sockets But clicking the “Invert others” button affects the other /color users, but not the user who actually clicked the button! The key here is the broadcast flag when the server receives and retransmits the invert message: // server.js socket . on ( ' invert ' , () => { socket . broadcast . emit ( ' invert ' ); // broadcast }); Enter fullscreen mode Exit fullscreen mode This flag means that that the server will send the event to every socket except the one it’s called on. Here this is just a neat trick, but in practice, it might be useful to avoid sending a post to the user who originally wrote it, because their client already has that information. Namespaces You may have noticed that the admin tab isn’t changing color with the other three. For simplicity, I didn’t set up any handlers for the admin page. But even if I had, they wouldn’t do anything, because the admin socket isn’t receiving those events at all. This is because the admin tab is in a different namespace . // color.html const socket = io ( ' /color ' ); // ======================= // admin.html const socket = io ( ' /admin ' ); // ======================= // index.js const colorNamespace = io . of ( ' /color ' ); const adminNamespace = io . of ( ' /admin ' ); … colorNamespace . emit ( ' set-color ' , color , value ); // the admin page doesn’t receive this event Enter fullscreen mode Exit fullscreen mode (For clarity, I gave my two namespaces the same names as the two endpoints the pages are located at, but I didn’t have to. The namespaces could have had arbitrary names with no change in functionality, as long as the client matched the server.) Namespaces provide a convenient way to target a subset of sockets. However, namespaces can communicate with each other: // admin.html const toggleFunction = ( color ) => { socket . emit ( ' toggle-active ' , color ); }; // ======================= // index.js // clicking the buttons on the admin page triggers changes on the color pages adminNamespace . on ( ' connection ' , ( socket ) => { socket . on ( ' toggle-active ' , color => { activeSettings [ color ] = ! activeSettings [ color ]; colorNamespace . emit ( ' toggle-active ' , color ); }); }); // ======================= // color.html socket . on ( ' toggle-active ' , ( color ) => { active [ color ] = ! active [ color ]; if ( controllingColor === color ) { colorSlider . disabled = ! active [ color ]; } document . getElementById ( ' active ' ). innerText = active [ controllingColor ] ? ' active ' : ' inactive ' ; updateBackground (); }); Enter fullscreen mode Exit fullscreen mode In all of the examples, events were caused by some interaction on one of the clients. An event was emitted to the server, and a second message was emitted by the server to the appropriate clients. However, this is only a small sample of the possibilities. For example, a server could use websockets to update all clients on a regular cycle, or get information from some API and pass it on. This demo is only a small showcase of what I’ve been learning and hope to keep applying in my projects going forward.

As DEV continues to grow, we want to ensure that DEV remains a place of integrity and inclusiveness. At DEV, we use Community Moderation as a tool to maintain a respectful and positive environment. It is important to us that we provide you all with the tools to identify and flag problems that may affect a single author or countless DEV users. In this post, we hope to provide simple and effective guidance to combat plagiarism as a community. Whether you’re reporting plagiarism as you stumble upon it or learning how to avoid it in your own writing, hopefully, you find this resource helpful! What is Plagiarism? Oxford Languages defines plagiarism as, "the practice of taking someone else's work or ideas and passing them off as one's own," however, plagiarism is multifaceted and it’s not always so clear as this. Bowdoin University wrote a great breakdown of the four most common types of plagiarism , in tl:dr fashion these are: "Direct Plagiarism" "Self Plagiarism" "Mosaic Plagiarism" "Accidental Plagiarism" Let's take a little deeper look into each… Direct Plagiarism is the most blatant form of plagiarism we encounter. This pertains to a user copying and pasting content from another blog, piece of media, or document, and claiming it as their own. Self Plagiarism is described through an academic lens in the Bowdoin University article which is not as relevant to our community, but we can think of this in a different way. For instance, you could potentially self-plagiarize by reposting an article you wrote for a company or publication, if they own your work. In many circumstances, these places will be happy for you to repost your work elsewhere, but make sure that you understand the terms and conditions of your writing before reposting. Mosaic Plagiarism generally starts when someone is inspired by another user's work and wants to write about the same topic. This occasionally manifests as copying and pasting certain passages of someone else’s work or as Bowdoin says “ finds synonyms for the author’s language while keeping to the same general structure and meaning of the original ” but failing to cite the original author. (Notice how we were able to link directly to the specific language in the text... every extra step we can take to clarify where the info came from is ideal!) Accidental Plagiarism happens when folks misquote their sources, forget to cite sources, or copy their sources too closely by accident (like mosaic plagiarism). How to Avoid Plagiarizing Someone's Work? Luckily, avoiding plagiarism is pretty easy once you know how to identify it. Typically, it is as simple as providing a straightforward source and citation to any media you use that is not your own in your post. When should I cite something? If you're pulling information from an external source that you did not create, you should always cite where the information came from. For example, say you're writing an article on using an npm package, axios, and you're using information from their documentation — you should link their docs in your article. This not only gives them credit for their work but also helps the DEV community in case someone wants to do more research about the topic. If you copy a source directly — use quotes and absolutely provide a source + citation. If you just looked at a source and paraphrased it in your own words, you don't need to use quotations, but it is still best to cite the source. If in doubt, always provide a source + citation! It's unlikely anyone will fault you for offering too many citations or listing too many sources. How should I cite something? Great question! See how I linked to the university's actual post on plagiarism ( the source ) and quoted the plagiarism types that they named. Notice that I didn't try to misappropriate these ideas as my own in any way and made it explicitly clear that this information came from Bowdoin University. This allows readers to do more research at the original source and ensures that the writers receive fair credit. A Note on AI Assisted Plagiarism We understand that there are AI tools (like ChatGPT) that can be used to aid in content creation. When used responsibly, these tools can be really cool and are generally allowed on the platform. However, these tools also have the potential for abuse. Please review our guidelines for using AI-assisted tools in your writing here: Guidelines for AI-assisted Articles on DEV Erin Bensinger for The DEV Team ・ Dec 19 '22 #meta #chatgpt #writing #abotwrotethis You should check out the full guidelines, but in regards to plagiarism, take care not to use AI to copy someone’s work unwittingly… and of course, don’t do it on purpose either! Always do your research and be responsible, making sure to cite sources if appropriate and disclose whatever tool you used to write your article. And even then, using AI does not excuse you from posting an article that plagiarizes others’ works. If we discover that you have done so, we will act to unpublish any offending posts and may suspend your DEV account. Be mindful and don’t let your usage of AI cause you to plagiarize. How to Recognize & Report Plagiarism? Now that you know how to properly cite sources, let's talk a bit about how to recognize plagiarism and where to go to report it. Recognizing Plagiarism Sometimes you just get the feeling that something is being plagiarized. Maybe you feel like you read it somewhere before. Or perhaps you notice a sharp change in the author’s voice. Maybe you see strange errors that occur from copying/pasting! Do a little detective work by dropping chunks of the text into your search engine of choice (or try the “quick search” option on plagium.com), and see if you can find any results with similar wording. If you do, report it to us ! (More on that below!) And of course, plagiarism doesn’t just happen in writing — it’s just as important to attribute images, code, videos, and other media. If you see a graph (or code block) you recognize from elsewhere, try to place it, and again, let us know. You might find the reverse image search at tineye.com helpful for seeing if an image is plagiarized! Other times, you may notice that someone isn't taking content from another source word-for-word, but their content feels too close to the original for comfort. Alternatively, maybe their graph is in blue instead of red like the original, or maybe their code has slightly different variables but is otherwise the same as someone else’s. If you feel like it’s off, report it and let us know why! What about those times when someone seems to be claiming that a repo or CodePen is theirs (when it's not)? ... Definitely reportable! As for examples that likely should not be reported: someone is reposting their own work that they first posted elsewhere someone is giving a shout-out to someone else's work or has written a companion piece/response to someone else's post (while making it clear it's unaffiliated) Reporting Plagiarism If you believe you’ve encountered plagiarism or copyright violations, the absolute BEST action you can take is to report the post and provide any evidence you have. Reporting the post sends it directly to our community team to take action. If you're unsure, it's okay to send it to us for review... we won't penalize you for being mistaken. All this said, we do not recommend calling anyone out in the comments section — as we discussed before, plagiarism can be accidental and/or is sometimes enforced differently in a variety of cultures. We ask that you simply report the post rather than getting personally involved which could accidentally trigger arguments, hurt feelings, or possibly even further conduct violations. Thank you! If you have questions or feedback about our approach, we encourage you to contact us via support@dev.to . If you believe that someone isn't following these guidelines, please don't hesitate to report them to us via our Report Abuse page . Also, if you want to help enforce the Code of Conduct, you might consider becoming a DEV moderator. Visit the DEV Community Moderation page for more information on roles and how to get involved.

Report Abuse Flo Posted on Jan 12 I tried to capture system audio in the browser. Here's what I learned. # webdev # javascript # learning # api I'm building LiveSuggest, a real-time AI assistant that listens to your meetings and gives you suggestions as you talk. Simple idea, right? Turns out, capturing audio from a browser tab is... complicated. The good news Chrome and Edge support it. You use getDisplayMedia , the same API for screen sharing, but with an audio option: const stream = await navigator . mediaDevices . getDisplayMedia ({ video : true , audio : { systemAudio : ' include ' } }); Enter fullscreen mode Exit fullscreen mode The user picks a tab to share, checks "Share tab audio", and boom — you get the audio stream. Works great for Zoom, Teams, Meet, whatever runs in a browser tab. The bad news Firefox? Implements getDisplayMedia but completely ignores the audio part. No error, no warning. You just... don't get audio. Safari? Same story. The API exists, audio doesn't. Mobile browsers? None of them support it. iOS, Android, doesn't matter. So if you're building something that needs system audio, you're looking at Chrome/Edge desktop only. That's maybe 60-65% of your potential users. What I ended up doing I detect the browser upfront and show a clear message: "Firefox doesn't support system audio capture for meetings. Use Chrome or Edge for this feature. Microphone capture is still available." No tricks, no workarounds. Just honesty. Users appreciate knowing why something doesn't work rather than wondering if they did something wrong. For Firefox/Safari users, the app falls back to microphone-only mode. It's not ideal for capturing both sides of a conversation, but it's better than nothing. The annoying details A few things that wasted my time so they don't waste yours: You have to request video. Even if you only want audio. video: true is mandatory. I immediately stop the video track after getting the stream, but you can't skip it. The "Share tab audio" checkbox is easy to miss. Chrome shows it in the sharing dialog, but it's not checked by default. If your user doesn't check it, you get a stream with zero audio tracks. No error, just silence. The stream can die anytime. User clicks "Stop sharing" in Chrome's toolbar? Your stream ends. You need to listen for the ended event and handle it gracefully. Was it worth it? Absolutely. For the browsers that support it, capturing tab audio is a game-changer. You can build things that weren't possible before — meeting assistants, live translators, accessibility tools. Just go in knowing that you'll spend time on browser detection and fallbacks. That's the web in 2025. If you're curious about what I built, check out LiveSuggest .

Report Abuse Sergiy Yevtushenko Posted on Jan 12 • Originally published at pragmatica.dev The Underlying Process of Request Processing # java # functional # architecture # backend The Underlying Process of Request Processing Beyond Languages and Frameworks Every request your system handles follows the same fundamental process. It doesn't matter if you're writing Java, Rust, or Python. It doesn't matter if you're using Spring, Express, or raw sockets. The underlying process is universal because it mirrors how humans naturally solve problems. When you receive a question, you don't answer immediately. You gather context. You retrieve relevant knowledge. You combine pieces of information. You transform raw data into meaningful understanding. Only then do you formulate a response. This is data transformation--taking input and gradually collecting necessary pieces of knowledge to provide a correct answer. Software request processing works identically. The Universal Pattern Every request follows these stages: Parse - Transform raw input into validated domain objects Gather - Collect necessary data from various sources Process - Apply business logic to produce results Respond - Transform results into appropriate output format This isn't a framework pattern. It's not a design choice. It's the fundamental nature of information processing. Whether you're handling an HTTP request, processing a message from a queue, or responding to a CLI command--the process is the same. Input → Parse → Gather → Process → Respond → Output Enter fullscreen mode Exit fullscreen mode Each stage transforms data. Each stage may need additional data. Each stage may fail. The entire flow is a data transformation pipeline. Why Async Looks Like Sync Here's the insight that changes everything: when you think in terms of data transformation, the sync/async distinction disappears . Consider these two operations: // "Synchronous" Result < User > user = database . findUser ( userId ); // "Asynchronous" Promise < User > user = httpClient . fetchUser ( userId ); Enter fullscreen mode Exit fullscreen mode From a data transformation perspective, these are identical: Both take a user ID Both produce a User (or failure) Both are steps in a larger pipeline The only difference is when the result becomes available. But that's an execution detail, not a structural concern. Your business logic doesn't care whether the data came from local memory or crossed an ocean. It cares about what the data is and what to do with it. When you structure code as data transformation pipelines, this becomes obvious: // The structure is identical regardless of sync/async return userId . all ( id -> findUser ( id ), // Might be sync or async id -> loadPermissions ( id ), // Might be sync or async id -> fetchPreferences ( id ) // Might be sync or async ). map ( this :: buildContext ); Enter fullscreen mode Exit fullscreen mode The pattern doesn't change. The composition doesn't change. Only the underlying execution strategy changes--and that's handled by the types, not by you. Parallel Execution Becomes Transparent The same principle applies to parallelism. When operations are independent, they can run in parallel. When they depend on each other, they must run sequentially. This isn't a choice you make--it's determined by the data flow. // Sequential: each step needs the previous result return validateInput ( request ) . flatMap ( this :: createUser ) . flatMap ( this :: sendWelcomeEmail ); // Parallel: steps are independent return Promise . all ( fetchUserProfile ( userId ), loadAccountSettings ( userId ), getRecentActivity ( userId ) ). map ( this :: buildDashboard ); Enter fullscreen mode Exit fullscreen mode You don't decide "this should be parallel" or "this should be sequential." You express the data dependencies. The execution strategy follows from the structure. If operations share no data dependencies, they're naturally parallelizable. If one needs another's output, they're naturally sequential. This is why thinking in data transformation is so powerful. You describe what needs to happen and what data flows where . The how --sync vs async, sequential vs parallel--emerges from the structure itself. The JBCT Patterns as Universal Primitives Java Backend Coding Technology captures this insight in six patterns: Leaf - Single transformation (atomic) Sequencer - A → B → C, dependent chain (sequential) Fork-Join - A + B + C → D, independent merge (parallel-capable) Condition - Route based on value (branching) Iteration - Transform collection (map/fold) Aspects - Wrap transformation (decoration) These aren't arbitrary design patterns. They're the fundamental ways data can flow through a system: Transform a single value (Leaf) Chain dependent transformations (Sequencer) Combine independent transformations (Fork-Join) Choose between transformations (Condition) Apply transformation to many values (Iteration) Enhance a transformation (Aspects) Every request processing task--regardless of domain, language, or framework--decomposes into these six primitives. Once you internalize this, implementation becomes mechanical. You're not inventing structure; you're recognizing the inherent structure of the problem. Optimal Implementation as Routine When you see request processing as data transformation, optimization becomes straightforward: Identify independent operations → They can parallelize (Fork-Join) Identify dependent chains → They must sequence (Sequencer) Identify decision points → They become conditions Identify collection processing → They become iterations Identify cross-cutting concerns → They become aspects You're not making architectural decisions. You're reading the inherent structure of the problem and translating it directly into code. This is why JBCT produces consistent code across developers and AI assistants. There's essentially one correct structure for any given data flow. Different people analyzing the same problem arrive at the same solution--not because they memorized patterns, but because the patterns are the natural expression of data transformation. The Shift in Thinking Traditional programming asks: "What sequence of instructions produces the desired effect?" Data transformation thinking asks: "What shape does the data take at each stage, and what transformations connect them?" The first approach leads to imperative code where control flow dominates. The second leads to declarative pipelines where data flow dominates. When you make this shift: Async stops being "harder" than sync Parallel stops being "risky" Error handling stops being an afterthought Testing becomes straightforward (pure transformations are trivially testable) You're no longer fighting the machine to do what you want. You're describing transformations and letting the runtime figure out the optimal execution strategy. Conclusion Request processing is data transformation. This isn't a paradigm or a methodology--it's the underlying reality that every paradigm and methodology is trying to express. Languages and frameworks provide different syntax. Some make data transformation easier to express than others. But the fundamental process doesn't change. Input arrives. Data transforms through stages. Output emerges. JBCT patterns aren't rules to memorize. They're the vocabulary for describing data transformation in Java. Once you see the underlying process clearly, using these patterns becomes as natural as describing what you see. The result: any processing task, implemented in close to optimal form, as a matter of routine. Part of Java Backend Coding Technology - a methodology for writing predictable, testable backend code.

Report Abuse Sagar Posted on Jan 13 • Originally published at sagarparmarr.hashnode.dev GenX: From Childhood Flipbooks to Premium Scroll Animation # webdev # performance # animation Build buttery-smooth, Apple-style image sequence animations on canvas + the tiny redraw hack that saves up to 80% GPU/battery power Hey there, fellow web dev enthusiasts! 🖐️ Remember those childhood flipbooks where you'd scribble a stick figure on the corner of your notebook pages, flip through them furiously, and suddenly – bam – your doodle was dancing? That's the nostalgic spark behind one of the coolest tricks in modern web design: image sequence animations . You've seen them on slick landing pages – those buttery-smooth, scroll-driven "videos" that feel alive as you navigate the site. But here's the plot twist: they're not videos at all . They're just a clever stack of images, orchestrated like a symphony on a <canvas> element. In this post, we're diving into how these animations work, why they're a game-changer for interactive storytelling, and – drumroll please 🥁 – a tiny optimization that stops your user's device from chugging power like it's training for a marathon. Let's flip the page and get started! ✨ Classic flipbook magic – the inspiration behind modern web wizardry Quick access (want to play right away?) → Live Demo → Full source code on GitHub Now let's get into how this magic actually works... Chapter 1: The Flipbook Reborn – What Is Image Sequence Animation? Picture this: You're on a high-end e-commerce site, scrolling down a product page. As your finger glides, a 3D model spins seamlessly, or a background scene morphs from day to night. It looks like high-def video, but peek at the network tab – no MP4 in sight . Instead, it's a barrage of optimized images (usually 100–200 WebP files) doing the heavy lifting. At its core, image sequence animation is digital flipbook wizardry : Export a video/animation as individual frames Preload them into memory as HTMLImageElement objects Drive playback with scroll position (0% = frame 1, 100% = last frame) Render the right frame on <canvas> Why choose this over <video> ? 🎮 Total control — perfect sync with scroll, hover, etc. ⚡ Lightweight hosting — images cache beautifully on CDNs, compress with WebP/AVIF 😅 No encoding drama — skip codecs, bitrates, and cross-browser video nightmares But every hero has a weakness: lots of network requests + heavy repainting = GPU sweat & battery drain on big/retina screens. We'll fix that soon. Smooth scroll-triggered image sequence in action Chapter 2: Behind the Curtain – How the Magic Happens (With Code!) Here's the typical flow in a React-ish world (pseudocode – adapt to vanilla/Vue/Svelte/whatever you love): // React-style pseudocode – hook it up to your scroll listener! const FRAME_COUNT = 192 ; // Your total frames const targetFrameRef = useRef ( 0 ); // Scroll-driven goal const currentFrameRef = useRef ( 0 ); // Current position const rafRef = useRef < number | null > ( null ); // Update target on scroll (progress: 0-1) function onScrollChange ( progress : number ) { const nextTarget = Math . round ( progress * ( FRAME_COUNT - 1 )); targetFrameRef . current = Math . clamp ( nextTarget , 0 , FRAME_COUNT - 1 ); // Assuming a clamp util } // The animation loop: Lerp and draw useEffect (() => { const tick = () => { const curr = currentFrameRef . current ; const target = targetFrameRef . current ; const diff = target - curr ; const step = Math . abs ( diff ) < 0.001 ? 0 : diff * 0.2 ; // Close the gap by 20% each frame const next = step === 0 ? target : curr + step ; currentFrameRef . current = next ; drawFrame ( Math . round ( next )); // Render the frame rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => { if ( rafRef . current ) cancelAnimationFrame ( rafRef . current ); }; }, []); function drawFrame ( index : number ) { const ctx = canvasRef . current ?. getContext ( ' 2d ' ); if ( ! ctx ) return ; // Clear, fill background, and draw image with contain-fit const img = preloadedImages [ index ]; ctx . clearRect ( 0 , 0 , canvas . width , canvas . height ); // ...aspect ratio calculations and drawImage() here... } Enter fullscreen mode Exit fullscreen mode Elegant, right? But here's the villain... The Plot Twist: Idle Repaints = Battery Vampires 🧛♂️ When users pause to read copy or admire the product, that requestAnimationFrame loop keeps churning 60 times per second … redrawing the exact same frame over and over. On high-DPI/4K retina screens? → Massive canvas clears → Repeated image scaling & smoothing → Constant GPU compositing The result: laptop fans kick into overdrive, the device heats up, and battery life tanks fast. I've seen (and measured) this in real projects — idle GPU/CPU spikes that turn a "premium" experience into a power hog. Time for the hero upgrade! Here are real before/after screenshots from my own testing using Chrome DevTools with Frame Rendering Stats enabled (GPU memory + frame rate overlay visible): Before: ~15.6 MB GPU idle After: ~2.4 MB GPU idle Before Optimization After Optimization Idle state with constant repaints – 15.6 MB GPU memory used Idle state post-hack – only 2.4 MB GPU memory used See the difference? Before : ~15.6 MB GPU memory in idle → heavy, wasteful repainting After : ~2.4 MB GPU memory → zen-like efficiency This tiny check eliminates redundant drawImage() calls and can drop idle GPU usage by up to 80% in heavy canvas scenarios (your mileage may vary based on resolution, DPR, and image size). Pro tip: Enable Paint flashing (green highlights) + Frame Rendering Stats in DevTools → scroll a bit, then pause. Watch the green flashes disappear and GPU stats stabilize after applying the fix. Battery saved = happier users + longer sessions 🌍⚡ Chapter 3: The Hero's Hack – Redraw Only When It Matters Super simple fix: track the last drawn frame index and skip drawImage() if nothing changed. useEffect (() => { let prevFrameIndex = Math . round ( currentFrameRef . current ); const tick = () => { // ... same lerp logic ... currentFrameRef . current = next ; const nextFrameIndex = Math . round ( next ); // ★ The magic line ★ if ( nextFrameIndex !== prevFrameIndex ) { drawFrame ( nextFrameIndex ); prevFrameIndex = nextFrameIndex ; } rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => cancelAnimationFrame ( rafRef . current ! ); }, []); Enter fullscreen mode Exit fullscreen mode Why this feels like a superpower Scrolling → still buttery-smooth (draws only when needed) Idle → zen mode (just cheap math, no GPU pain) Real-world wins → up to 80% less idle GPU usage in my tests Pro tip: Use Paint Flashing + Performance tab in DevTools to see the difference yourself. Try it yourself! Here's a minimal, production-ready demo you can fork and play with: → Live Demo → Full source code on GitHub Extra Twists: Level Up Your Animation Game ⚙️ DPR Clamp → cap devicePixelRatio at 2 🖼️ Smart contain-fit drawing (calculate once) 🚀 WebP/AVIF + CDN caching 👀 IntersectionObserver + document.hidden → pause when out of view 🔼 Smart preloading → prioritize first visible frames The Grand Finale: Flipbooks for the Future Image sequence animations are the unsung heroes of immersive web experiences – turning static pages into interactive stories without video baggage . With this tiny redraw check, you're building cool and efficient experiences. Your users (and their batteries) will thank you. Got questions, your own hacks, or want to share a project?

Report Abuse Sergiy Yevtushenko Posted on Jan 12 • Originally published at pragmatica.dev The Underlying Process of Request Processing # java # functional # architecture # backend The Underlying Process of Request Processing Beyond Languages and Frameworks Every request your system handles follows the same fundamental process. It doesn't matter if you're writing Java, Rust, or Python. It doesn't matter if you're using Spring, Express, or raw sockets. The underlying process is universal because it mirrors how humans naturally solve problems. When you receive a question, you don't answer immediately. You gather context. You retrieve relevant knowledge. You combine pieces of information. You transform raw data into meaningful understanding. Only then do you formulate a response. This is data transformation--taking input and gradually collecting necessary pieces of knowledge to provide a correct answer. Software request processing works identically. The Universal Pattern Every request follows these stages: Parse - Transform raw input into validated domain objects Gather - Collect necessary data from various sources Process - Apply business logic to produce results Respond - Transform results into appropriate output format This isn't a framework pattern. It's not a design choice. It's the fundamental nature of information processing. Whether you're handling an HTTP request, processing a message from a queue, or responding to a CLI command--the process is the same. Input → Parse → Gather → Process → Respond → Output Enter fullscreen mode Exit fullscreen mode Each stage transforms data. Each stage may need additional data. Each stage may fail. The entire flow is a data transformation pipeline. Why Async Looks Like Sync Here's the insight that changes everything: when you think in terms of data transformation, the sync/async distinction disappears . Consider these two operations: // "Synchronous" Result < User > user = database . findUser ( userId ); // "Asynchronous" Promise < User > user = httpClient . fetchUser ( userId ); Enter fullscreen mode Exit fullscreen mode From a data transformation perspective, these are identical: Both take a user ID Both produce a User (or failure) Both are steps in a larger pipeline The only difference is when the result becomes available. But that's an execution detail, not a structural concern. Your business logic doesn't care whether the data came from local memory or crossed an ocean. It cares about what the data is and what to do with it. When you structure code as data transformation pipelines, this becomes obvious: // The structure is identical regardless of sync/async return userId . all ( id -> findUser ( id ), // Might be sync or async id -> loadPermissions ( id ), // Might be sync or async id -> fetchPreferences ( id ) // Might be sync or async ). map ( this :: buildContext ); Enter fullscreen mode Exit fullscreen mode The pattern doesn't change. The composition doesn't change. Only the underlying execution strategy changes--and that's handled by the types, not by you. Parallel Execution Becomes Transparent The same principle applies to parallelism. When operations are independent, they can run in parallel. When they depend on each other, they must run sequentially. This isn't a choice you make--it's determined by the data flow. // Sequential: each step needs the previous result return validateInput ( request ) . flatMap ( this :: createUser ) . flatMap ( this :: sendWelcomeEmail ); // Parallel: steps are independent return Promise . all ( fetchUserProfile ( userId ), loadAccountSettings ( userId ), getRecentActivity ( userId ) ). map ( this :: buildDashboard ); Enter fullscreen mode Exit fullscreen mode You don't decide "this should be parallel" or "this should be sequential." You express the data dependencies. The execution strategy follows from the structure. If operations share no data dependencies, they're naturally parallelizable. If one needs another's output, they're naturally sequential. This is why thinking in data transformation is so powerful. You describe what needs to happen and what data flows where . The how --sync vs async, sequential vs parallel--emerges from the structure itself. The JBCT Patterns as Universal Primitives Java Backend Coding Technology captures this insight in six patterns: Leaf - Single transformation (atomic) Sequencer - A → B → C, dependent chain (sequential) Fork-Join - A + B + C → D, independent merge (parallel-capable) Condition - Route based on value (branching) Iteration - Transform collection (map/fold) Aspects - Wrap transformation (decoration) These aren't arbitrary design patterns. They're the fundamental ways data can flow through a system: Transform a single value (Leaf) Chain dependent transformations (Sequencer) Combine independent transformations (Fork-Join) Choose between transformations (Condition) Apply transformation to many values (Iteration) Enhance a transformation (Aspects) Every request processing task--regardless of domain, language, or framework--decomposes into these six primitives. Once you internalize this, implementation becomes mechanical. You're not inventing structure; you're recognizing the inherent structure of the problem. Optimal Implementation as Routine When you see request processing as data transformation, optimization becomes straightforward: Identify independent operations → They can parallelize (Fork-Join) Identify dependent chains → They must sequence (Sequencer) Identify decision points → They become conditions Identify collection processing → They become iterations Identify cross-cutting concerns → They become aspects You're not making architectural decisions. You're reading the inherent structure of the problem and translating it directly into code. This is why JBCT produces consistent code across developers and AI assistants. There's essentially one correct structure for any given data flow. Different people analyzing the same problem arrive at the same solution--not because they memorized patterns, but because the patterns are the natural expression of data transformation. The Shift in Thinking Traditional programming asks: "What sequence of instructions produces the desired effect?" Data transformation thinking asks: "What shape does the data take at each stage, and what transformations connect them?" The first approach leads to imperative code where control flow dominates. The second leads to declarative pipelines where data flow dominates. When you make this shift: Async stops being "harder" than sync Parallel stops being "risky" Error handling stops being an afterthought Testing becomes straightforward (pure transformations are trivially testable) You're no longer fighting the machine to do what you want. You're describing transformations and letting the runtime figure out the optimal execution strategy. Conclusion Request processing is data transformation. This isn't a paradigm or a methodology--it's the underlying reality that every paradigm and methodology is trying to express. Languages and frameworks provide different syntax. Some make data transformation easier to express than others. But the fundamental process doesn't change. Input arrives. Data transforms through stages. Output emerges. JBCT patterns aren't rules to memorize. They're the vocabulary for describing data transformation in Java. Once you see the underlying process clearly, using these patterns becomes as natural as describing what you see. The result: any processing task, implemented in close to optimal form, as a matter of routine. Part of Java Backend Coding Technology - a methodology for writing predictable, testable backend code.

Report Abuse Ed Wantuil Posted on Jan 12 Cloud Sem Falência: O mínimo que você precisa saber de FinOps # devops # cloud # braziliandevs Imagine a cena: você trabalha em uma empresa consolidada. Vocês têm aquele rack de servidores físicos robusto, piscando luzinhas em uma sala gelada, com piso elevado e controle biométrico (o famoso On-Premise ). Tudo funciona. O banco de dados aguenta o tranco, a latência é zero na rede local. Mas a diretoria decide que é hora de "modernizar". "Vamos migrar para a Nuvem!" , dizem eles, com os olhos brilhando. A promessa no PowerPoint é sedutora: flexibilidade infinita , segurança gerenciada e o mantra mágico: "pagar só pelo que usar" . A migração acontece via Lift-and-Shift (pegar o que existe e jogar na nuvem sem refatorar). A equipe de Infra e Dev comemoram. O Deploy é um sucesso. Três meses depois, chega a fatura da AWS. O diretor financeiro (CFO) não apenas cai da cadeira; ele convoca uma reunião de emergência. O custo, que antes era uma linha fixa e previsível no balanço anual, triplicou e agora flutua violentamente. O que deu errado? Simples: A engenharia tratou a Nuvem como um Data Center físico, apenas alugado. Hoje, vamos falar sobre os riscos dessa mudança e como aplicar FinOps não como burocracia, mas como requisito de arquitetura. (Nota: Usaremos a AWS nos exemplos por ser a stack padrão de mercado, mas a lógica se aplica integralmente ao Azure, GCP e OCI). 🦄 A Ilusão da Mágica: CAPEX vs. OPEX na Engenharia Para entender a conta da AWS, você precisa entender como o dinheiro sai do cofre da empresa. A mudança da nuvem não é apenas sobre onde o servidor roda, é sobre quem assume o risco do desperdício. 1. CAPEX (Capital Expenditure): A Lógica do "PC Gamer" CAPEX é Despesa de Capital. É comprar a "caixa". Imagine que você vai montar um PC Gamer High-End. Você gasta R$ 20.000,00 na loja. Doeu no bolso na hora, certo? Mas depois que o PC está na sua mesa: Custo Marginal Zero: Se você jogar Paciência ou renderizar um vídeo em 8K a noite toda, não faz diferença financeira para o seu bolso (tirando a conta de luz, que é irrisória perto do hardware). O dinheiro já foi gasto ( Sunk Cost ). O Comportamento do Engenheiro (On-Premise): Como o processo de compra é lento (meses de cotação e aprovação), você tem medo de faltar recurso. Mentalidade: "Vou pedir um servidor com 64 Cores, mesmo precisando de 16. Se sobrar, melhor. O hardware é nosso mesmo." Código: Eficiência não é prioridade financeira. Um código mal otimizado que consome 90% da CPU não gera uma fatura extra no fim do mês. 2. OPEX (Operational Expenditure): A Lógica do Uber OPEX é Despesa Operacional. É o custo de funcionamento do dia a dia. Na nuvem, você não comprou o carro; você está rodando de Uber 24 horas por dia. Custo Marginal Real: Cada minuto parado no sinal custa dinheiro. Cada desvio de rota custa dinheiro. O Comportamento do Engenheiro (Cloud): Aqui, a ineficiência é taxada instantaneamente. Mentalidade: Aquele servidor de 64 cores e 512GB de ram parado esperando tráfego é como deixar o Uber te esperando na porta do escritório enquanto você trabalha. O taxímetro está rodando. Código: Um loop infinito ou uma query sem índice no banco de dados não deixa apenas o sistema lento; ele queima dinheiro vivo . Comparativo para Desenvolvedores (Salve isso) Feature CAPEX (On-Premise / Hardware Próprio) OPEX (Cloud / AWS / Azure) Commit Financeiro Você paga tudo antes de usar (Upfront). Você paga depois de usar (Pay-as-you-go). Latência de Aprovação Alta. Precisa de reuniões, assinaturas e compras. Zero. Um terraform apply gasta dinheiro instantaneamente. Risco de Capacidade Subutilização. Comprar um servidor monstro e usar 10%. Conta Surpresa. Esquecer algo ligado ou escalar infinitamente. Otimização de Código Melhora performance, mas não reduz a fatura do hardware. Reduz diretamente a fatura. Código limpo = Dinheiro no caixa. Por que isso afeta a sua Arquitetura? Se você desenha uma arquitetura pensando em CAPEX (Mundo Físico) e a implementa em OPEX (Nuvem), você cria um desastre financeiro. No CAPEX , a estratégia de defesa é: "Superdimensionar para garantir estabilidade". (Compre o maior servidor possível). No OPEX , a estratégia de defesa é: "Elasticidade". (Comece com o menor servidor possível e configure para crescer sozinho apenas se necessário). 💸 Os 8 Cavaleiros do Apocalipse Financeiro na AWS Na nuvem, os maiores vilões raramente são tecnologias complexas de IA ou Big Data. Quase sempre são decisões arquiteturais preguiçosas e falta de governança . 1. Instâncias "Just in Case": O Custo do Seguro Psicológico O sobredimensionamento é um vício comum: o desenvolvedor sobe uma instância m5.2xlarge (8 vCPUs, 32GB RAM) não porque a aplicação exige, mas porque ele "não quer ter dor de cabeça". É o provisionamento baseado no medo, criando uma margem de segurança gigantesca e cara para evitar qualquer risco hipotético de lentidão. A realidade nua e crua aparece no CloudWatch: na maior parte do tempo, essa supermáquina opera com apenas 12% de CPU e usa uma fração da memória. Pagar por uma 2xlarge para rodar essa carga é como fretar um ônibus de 50 lugares para levar apenas 4 pessoas ao trabalho todos os dias. Você está pagando pelo "espaço vazio" e pelo motor potente do ônibus, enquanto um carro popular ( t3.medium ) faria o mesmo trajeto com o mesmo conforto e muito mais economia. 2. Ambientes Zumbis: A Torneira Aberta Fora do Expediente "Ambientes Zumbis" são servidores de Desenvolvimento e Homologação que operam como cópias fiéis da Produção, mas sem a audiência dela. Eles permanecem ligados e faturando às 3 da manhã de um domingo, consumindo recursos de nuvem para processar absolutamente nada. Manter esses servidores ligados 24/7 é o equivalente digital de deixar o ar-condicionado de um escritório ligado no máximo durante todo o fim de semana , com o prédio completamente vazio. O impacto financeiro atua como um multiplicador de desperdício. Se você mantém três ambientes (Dev, Staging e Produção) com arquiteturas similares ligados ininterruptamente, seu custo base é 300% do necessário . A matemática é cruel: uma semana tem 168 horas, mas seus desenvolvedores trabalham apenas 40. Você está pagando por 128 horas de ociosidade pura por máquina, todas as semanas. A primeira cura para esse desperdício é o agendamento automático. Utilizando soluções como o AWS Instance Scheduler (ou Lambdas simples), configuramos os ambientes para "acordar" às 08:00 e "dormir" às 20:00, de segunda a sexta-feira. Apenas essa automação básica, sem alterar uma linha de código da aplicação, reduz a fatura desses ambientes não-produtivos em cerca de 70% . 3. O Esquecimento Crônico: O Custo do Limbo Um dos "pegadinhas" mais comuns da nuvem acontece no momento de desligar as luzes: quando você termina uma instância EC2, o senso comum diz que a cobrança para. O erro está em assumir que a máquina e o disco são uma peça única. Por padrão, ao "matar" o servidor, o volume de armazenamento (EBS) acoplado a ele muitas vezes sobrevive, entrando num estado de limbo financeiro. O resultado é o acúmulo de EBS Órfãos : centenas de discos no estado "Available" (não atrelados a ninguém), cheios de dados inúteis ou completamente vazios, pelos quais você paga o preço cheio do gigabyte provisionado. É comparável a vender seu carro, mas esquecer de cancelar o aluguel da vaga de garagem: o veículo não existe mais, mas a cobrança pelo espaço que ele ocupava continua chegando todo mês na fatura. A situação piora com os Elastic IPs (EIPs) , que possuem uma lógica de cobrança invertida e punitiva. Devido à escassez mundial de endereços IPv4, a AWS não cobra pelo IP enquanto você o utiliza, mas começa a cobrar assim que ele fica ocioso . É como uma "multa por não uso": se você reserva um endereço IP e não o atrela a uma instância em execução, você paga por estar "segurando" um recurso escasso sem necessidade. 4. O Cemitério de Dados no S3 Buckets S3 tendem a virar "cemitérios digitais" onde logs, backups e assets se acumulam indefinidamente. O erro crucial não é guardar os dados, mas a falta de estratégia: manter 100% desse volume na classe S3 Standard , pagando a tarifa mais alta da AWS por arquivos que ninguém acessa há meses. Para entender o prejuízo, imagine o S3 Standard como uma loja no corredor principal de um shopping: o aluguel é caríssimo porque o acesso é imediato e fácil ( baixa latência ). Manter logs de 2022 nessa classe é como alugar essa vitrine premium apenas para estocar caixas de papelão velhas. Dados "frios", que raramente são consultados, não precisam estar à mão em milissegundos; eles podem ficar num armazém mais distante e barato. A solução é o S3 Lifecycle , que automatiza a logística desse "estoque". Primeiro, ele atua na Transição : move automaticamente os dados que envelhecem da "vitrine" (Standard) para o "armazém" ( S3 Glacier ). No Glacier, você paga uma fração do preço, aceitando que o resgate do arquivo leve alguns minutos ou horas (maior latência), o que é aceitável para arquivos de auditoria ou backups antigos. Por fim, o Lifecycle resolve o acúmulo de lixo através da Expiração . Além de mover dados, você configura regras para deletar objetos definitivamente após um período, como remover logs temporários após 7 dias. Isso garante a higiene do ambiente, impedindo que você pague aluguel (seja no shopping ou no armazém) por dados inúteis que não deveriam mais existir. 5. Snapshots: O Colecionador de Backups Fantasmas Backups são a apólice de seguro da sua infraestrutura, mas a facilidade de criar snapshots na AWS gera um comportamento perigoso de acumulação. O erro clássico é configurar uma automação de snapshot diário e definir a retenção para "nunca" ou prazos absurdos como 5 anos. Embora os snapshots sejam incrementais (salvando apenas o que mudou), em bancos de dados transacionais com muita escrita, o volume de dados alterados cresce rápido, e a fatura acompanha. Para visualizar o desperdício, imagine que você compra o jornal do dia para ler as notícias. É útil ter os jornais da última semana na mesa para referência rápida. Mas guardar uma pilha de jornais diários de três anos atrás na sua sala ocupa espaço valioso e custa dinheiro, sendo que a chance de você precisar saber a "cotação do dólar numa terça-feira específica de 2021" é praticamente nula. Você está pagando armazenamento premium por "jornais velhos" que não têm valor de negócio. 6. Licenciamento Comercial (O Custo Invisível) Muitas empresas focam tanto em otimizar CPU e RAM que esquecem o elefante na sala: o custo de software. Ao rodar instâncias com Windows Server ou SQL Server Enterprise na AWS no modelo "License Included", você não paga apenas pela infraestrutura; você paga uma sobretaxa pesada pelo direito de uso do software proprietário. Esse custo é embutido na tarifa por hora e, em máquinas grandes, a licença pode custar mais caro que o próprio hardware. Para ilustrar a desproporção, usar o SQL Server Enterprise para uma aplicação que não utiliza funcionalidades avançadas (como Always On complexo ou compressão de dados específica) é como fretar um jato executivo apenas para ir comprar pão na padaria . O objetivo (armazenar e recuperar dados) é cumprido, mas você está pagando por um veículo de luxo quando uma bicicleta ou um Uber resolveria o problema com a mesma eficiência e uma fração do custo. A primeira camada de solução é a Otimização de Edição . É comum desenvolvedores solicitarem a versão Enterprise por "garantia" ou hábito, sem necessidade técnica real. Uma auditoria simples muitas vezes revela que a versão Standard atende a todos os requisitos da aplicação. Fazer esse downgrade reduz a fatura de licenciamento imediatamente, sem exigir mudanças drásticas na arquitetura ou no código. 7. Dilema Geográfico: Reduzindo a Fatura pela Metade Hospedar aplicações na região sa-east-1 (São Paulo) carrega um ágio pesado: o "Custo Brasil" digital faz com que a infraestrutura local custe, cerca de 50% a mais do que na us-east-1 (N. Virgínia). Migrar workloads para os EUA é, frequentemente, a manobra de FinOps com maior retorno imediato (ROI): você corta a fatura desses recursos praticamente pela metade apenas alterando o CEP do servidor, acessando o mesmo hardware por uma fração do preço. O principal bloqueador costuma ser o medo da LGPD , mas a crença de que a lei exige residência física dos dados no Brasil é um mito . O Artigo 33 permite a transferência internacional para países com proteção adequada (como os EUA), desde que coberto por contratos padrão. A legislação foca na segurança e privacidade do dado, não na sua latitude e longitude geográfica. Quanto à técnica, a latência para a Virgínia (~120ms) é imperceptível para a maioria das aplicações web, sistemas internos e dashboards. A estratégia inteligente é adotar uma região como US East como padrão para maximizar a economia, reservando São Paulo apenas para exceções que realmente exigem resposta em tempo real (como High Frequency Trading), evitando pagar preço de "primeira classe" para cargas de trabalho que rodariam perfeitamente na econômica. 8. Serverless: A Faca de Dois Gumes "Serverless" é computação sem gestão de infraestrutura (como AWS Lambda ou DynamoDB). Diferente de alugar um servidor fixo mensal, aqui você paga apenas pelos milissegundos que seu código executa ou pelo dado que você lê. É como a conta de luz: você só paga se o interruptor estiver ligado. A Estratégia: Para uso esporádico, é imbatível. Mas e para uso constante? Também pode ser uma excelente escolha! Embora a fatura de infraestrutura possa vir mais alta do que em servidores tradicionais, você elimina o trabalho pesado de manutenção. Muitas vezes, é financeiramente mais inteligente pagar um pouco mais para a AWS do que custear horas de engenharia ou contratar uma equipe dedicada apenas para gerenciar servidores, aplicar patches de segurança e configurar escalas. O segredo é olhar para o Custo Total (TCO), e não apenas para a linha de processamento na fatura. 🕵️♂️ FinOps: Engenharia Financeira na Prática FinOps não é apenas sobre "pedir desconto" ou cortar gastos; é a mudança cultural que descentraliza a responsabilidade do custo, empoderando engenheiros a tomar decisões baseadas em dados, não em palpites. Para que essa cultura saia do papel, ela precisa se apoiar em um tripé de governança robusto: a visibilidade granular garantida pelo tageamento correto (saber quem gasta), a segurança operacional monitorada pelo AWS Budgets (saber quando gasta) e a eficiência financeira obtida através dos Modelos de Compra inteligentes (saber como pagar). Sem integrar essas três frentes, a nuvem deixa de ser um acelerador de inovação para se tornar um passivo financeiro descontrolado. 1. TAGs: Sem Etiquetas, Sem Dados 🏷️ No AWS Cost Explorer, uma infraestrutura sem tags opera como uma "caixa preta" financeira: você encara uma fatura de $50.000, mas é incapaz de discernir se o rombo veio de um modelo crítico de Data Science ou de um cluster Kubernetes esquecido por um estagiário. Utiliza tags como custo:centro , app:nome , env e dono no momento dos recursos transformara números genéricos em rastreáveis, permitindo que cada centavo gasto tenha um responsável atrelado, eliminando definitivamente a cultura de que "o custo da nuvem não é problema meu". 2. AWS Budgets e Detecção de Anomalias 🚨 Não espere o fim do mês. Configure o AWS Budgets para alertar quando o custo projetado (forecasted) ultrapassar o limite. Dica: Ative o Cost Anomaly Detection . Ele usa Machine Learning para identificar picos anormais. Exemplo: Um deploy errado fez a cahamada para um Lambda entrar em loop infinito. O Anomaly Detection te avisa em horas, não no fim do mês. 3. Modelos de Compra: O Fim do On-Demand 💸 Operar 100% em On-Demand é pagar voluntariamente um "imposto sobre a falta de planejamento". A maturidade em FinOps exige abandonar o preço de varejo e adotar um mix estratégico: cubra sua carga de trabalho base (aquela que roda 24/7) com Savings Plans , que oferecem descontos de até 72% em troca de fidelidade, e mova cargas tolerantes a interrupções, como processamento de dados e pipelines de CI/CD, para Spot Instances , aproveitando a capacidade ociosa da AWS por até 10% do valor original . Ignorar essa estratégia e manter tudo no On-Demand é uma decisão consciente de desperdiçar orçamento que poderia ser reinvestido em inovação. 🧠 Dev Assina o Código e o Cheque No mundo On-Premise, um código ruim apenas deixava o sistema lento. Na Nuvem, código ineficiente gera uma fatura imediata . A barreira entre Engenharia e Financeiro desapareceu: cada linha de código é uma decisão de compra executada em tempo real. O desenvolvedor não consome apenas CPU, ele consome o orçamento da empresa. Para entender o impacto, veja o preço das más práticas: O Custo da Leitura: Uma query sem " WHERE " ou um Full Table Scan no DynamoDB não é apenas um problema de performance; você está pagando unidades de leitura para ler milhares de linhas inúteis. É como comprar a biblioteca inteira para ler uma única página. O Custo da Ineficiência: Um código com vazamento de memória engana o Auto Scaling . O sistema provisiona 10 servidores para fazer o trabalho de 2, desperdiçando dinheiro para compensar código ruim. O Custo do Ruído: Logs em modo VERBOSE esquecidos em produção são vilões. O CloudWatch cobra caro pela ingestão. Enviar gigabytes de "log de lixo" é literalmente pagar frete aéreo para transportar entulho. A Cultura de Engenharia Consciente de Custos: Estimativa no Refinamento: O custo deve ser debatido antes do código existir. Durante o Refinamento, ao definir a arquitetura, faça a pergunta: "Quais recursos vamos usar e quanto isso vai custar com a volumetria esperada?" . Se a solução técnica custa $1.000 para economizar $50 de esforço manual, ela deve ser vetada ali mesmo. Feedback Loop: O desenvolvedor precisa ver quanto o serviço dele custa. Painéis do Grafana ou Datadog devem mostrar não só a latência da API, mas o custo diário dela. Só existe responsabilidade quando existe consciência do preço. Cerimônia de Custo (FinOps Review): Estabeleça uma reunião recorrente dedicada a olhar o "Extrato da Conta" . O time analisa os custos atuais, investiga picos não planejados da semana anterior e discute ativamente: "Existe alguma oportunidade de desligar recursos ou otimizar este serviço agora?" . É a higiene financeira mantendo o projeto saudável. 🌐 O Mundo Híbrido e Multicloud: Complexidade é Custo Nem tudo precisa ir para a AWS, e nem tudo deve sair do seu Data Center local. A maturidade em nuvem não significa "desligar tudo o que é físico", mas sim saber onde cada peça do jogo custa menos. Empresas podem operam em modelos híbridos estratégicos: O Lugar do Legado (On-Premise): Aquele banco de dados gigante ou mainframe que já está quitado, não cresce mais e roda de forma previsível? Deixe onde está. Migrar esses monstros para a nuvem apenas copiando e colando ("Lift-and-Shift") costuma ser um desastre financeiro. Na nuvem, você paga caro por performance de disco (IOPS) e memória que, no seu servidor físico, já são "gratuitos". O Lugar da Inovação (Nuvem): Seu site, aplicativos móveis e APIs que precisam aguentar milhões de acessos num dia e zero no outro? Leve para a nuvem. Lá você paga pela elasticidade e pelo alcance global que o servidor físico não consegue entregar. Cuidado com a Armadilha Multicloud Muitos gestores caem na tentação de usar AWS, Azure e Google Cloud ao mesmo tempo sob o pretexto de "evitar ficar preso a um fornecedor" (Vendor Lock-in).

Report Abuse Ed Wantuil Posted on Jan 12 Cloud Sem Falência: O mínimo que você precisa saber de FinOps # devops # cloud # braziliandevs Imagine a cena: você trabalha em uma empresa consolidada. Vocês têm aquele rack de servidores físicos robusto, piscando luzinhas em uma sala gelada, com piso elevado e controle biométrico (o famoso On-Premise ). Tudo funciona. O banco de dados aguenta o tranco, a latência é zero na rede local. Mas a diretoria decide que é hora de "modernizar". "Vamos migrar para a Nuvem!" , dizem eles, com os olhos brilhando. A promessa no PowerPoint é sedutora: flexibilidade infinita , segurança gerenciada e o mantra mágico: "pagar só pelo que usar" . A migração acontece via Lift-and-Shift (pegar o que existe e jogar na nuvem sem refatorar). A equipe de Infra e Dev comemoram. O Deploy é um sucesso. Três meses depois, chega a fatura da AWS. O diretor financeiro (CFO) não apenas cai da cadeira; ele convoca uma reunião de emergência. O custo, que antes era uma linha fixa e previsível no balanço anual, triplicou e agora flutua violentamente. O que deu errado? Simples: A engenharia tratou a Nuvem como um Data Center físico, apenas alugado. Hoje, vamos falar sobre os riscos dessa mudança e como aplicar FinOps não como burocracia, mas como requisito de arquitetura. (Nota: Usaremos a AWS nos exemplos por ser a stack padrão de mercado, mas a lógica se aplica integralmente ao Azure, GCP e OCI). 🦄 A Ilusão da Mágica: CAPEX vs. OPEX na Engenharia Para entender a conta da AWS, você precisa entender como o dinheiro sai do cofre da empresa. A mudança da nuvem não é apenas sobre onde o servidor roda, é sobre quem assume o risco do desperdício. 1. CAPEX (Capital Expenditure): A Lógica do "PC Gamer" CAPEX é Despesa de Capital. É comprar a "caixa". Imagine que você vai montar um PC Gamer High-End. Você gasta R$ 20.000,00 na loja. Doeu no bolso na hora, certo? Mas depois que o PC está na sua mesa: Custo Marginal Zero: Se você jogar Paciência ou renderizar um vídeo em 8K a noite toda, não faz diferença financeira para o seu bolso (tirando a conta de luz, que é irrisória perto do hardware). O dinheiro já foi gasto ( Sunk Cost ). O Comportamento do Engenheiro (On-Premise): Como o processo de compra é lento (meses de cotação e aprovação), você tem medo de faltar recurso. Mentalidade: "Vou pedir um servidor com 64 Cores, mesmo precisando de 16. Se sobrar, melhor. O hardware é nosso mesmo." Código: Eficiência não é prioridade financeira. Um código mal otimizado que consome 90% da CPU não gera uma fatura extra no fim do mês. 2. OPEX (Operational Expenditure): A Lógica do Uber OPEX é Despesa Operacional. É o custo de funcionamento do dia a dia. Na nuvem, você não comprou o carro; você está rodando de Uber 24 horas por dia. Custo Marginal Real: Cada minuto parado no sinal custa dinheiro. Cada desvio de rota custa dinheiro. O Comportamento do Engenheiro (Cloud): Aqui, a ineficiência é taxada instantaneamente. Mentalidade: Aquele servidor de 64 cores e 512GB de ram parado esperando tráfego é como deixar o Uber te esperando na porta do escritório enquanto você trabalha. O taxímetro está rodando. Código: Um loop infinito ou uma query sem índice no banco de dados não deixa apenas o sistema lento; ele queima dinheiro vivo . Comparativo para Desenvolvedores (Salve isso) Feature CAPEX (On-Premise / Hardware Próprio) OPEX (Cloud / AWS / Azure) Commit Financeiro Você paga tudo antes de usar (Upfront). Você paga depois de usar (Pay-as-you-go). Latência de Aprovação Alta. Precisa de reuniões, assinaturas e compras. Zero. Um terraform apply gasta dinheiro instantaneamente. Risco de Capacidade Subutilização. Comprar um servidor monstro e usar 10%. Conta Surpresa. Esquecer algo ligado ou escalar infinitamente. Otimização de Código Melhora performance, mas não reduz a fatura do hardware. Reduz diretamente a fatura. Código limpo = Dinheiro no caixa. Por que isso afeta a sua Arquitetura? Se você desenha uma arquitetura pensando em CAPEX (Mundo Físico) e a implementa em OPEX (Nuvem), você cria um desastre financeiro. No CAPEX , a estratégia de defesa é: "Superdimensionar para garantir estabilidade". (Compre o maior servidor possível). No OPEX , a estratégia de defesa é: "Elasticidade". (Comece com o menor servidor possível e configure para crescer sozinho apenas se necessário). 💸 Os 8 Cavaleiros do Apocalipse Financeiro na AWS Na nuvem, os maiores vilões raramente são tecnologias complexas de IA ou Big Data. Quase sempre são decisões arquiteturais preguiçosas e falta de governança . 1. Instâncias "Just in Case": O Custo do Seguro Psicológico O sobredimensionamento é um vício comum: o desenvolvedor sobe uma instância m5.2xlarge (8 vCPUs, 32GB RAM) não porque a aplicação exige, mas porque ele "não quer ter dor de cabeça". É o provisionamento baseado no medo, criando uma margem de segurança gigantesca e cara para evitar qualquer risco hipotético de lentidão. A realidade nua e crua aparece no CloudWatch: na maior parte do tempo, essa supermáquina opera com apenas 12% de CPU e usa uma fração da memória. Pagar por uma 2xlarge para rodar essa carga é como fretar um ônibus de 50 lugares para levar apenas 4 pessoas ao trabalho todos os dias. Você está pagando pelo "espaço vazio" e pelo motor potente do ônibus, enquanto um carro popular ( t3.medium ) faria o mesmo trajeto com o mesmo conforto e muito mais economia. 2. Ambientes Zumbis: A Torneira Aberta Fora do Expediente "Ambientes Zumbis" são servidores de Desenvolvimento e Homologação que operam como cópias fiéis da Produção, mas sem a audiência dela. Eles permanecem ligados e faturando às 3 da manhã de um domingo, consumindo recursos de nuvem para processar absolutamente nada. Manter esses servidores ligados 24/7 é o equivalente digital de deixar o ar-condicionado de um escritório ligado no máximo durante todo o fim de semana , com o prédio completamente vazio. O impacto financeiro atua como um multiplicador de desperdício. Se você mantém três ambientes (Dev, Staging e Produção) com arquiteturas similares ligados ininterruptamente, seu custo base é 300% do necessário . A matemática é cruel: uma semana tem 168 horas, mas seus desenvolvedores trabalham apenas 40. Você está pagando por 128 horas de ociosidade pura por máquina, todas as semanas. A primeira cura para esse desperdício é o agendamento automático. Utilizando soluções como o AWS Instance Scheduler (ou Lambdas simples), configuramos os ambientes para "acordar" às 08:00 e "dormir" às 20:00, de segunda a sexta-feira. Apenas essa automação básica, sem alterar uma linha de código da aplicação, reduz a fatura desses ambientes não-produtivos em cerca de 70% . 3. O Esquecimento Crônico: O Custo do Limbo Um dos "pegadinhas" mais comuns da nuvem acontece no momento de desligar as luzes: quando você termina uma instância EC2, o senso comum diz que a cobrança para. O erro está em assumir que a máquina e o disco são uma peça única. Por padrão, ao "matar" o servidor, o volume de armazenamento (EBS) acoplado a ele muitas vezes sobrevive, entrando num estado de limbo financeiro. O resultado é o acúmulo de EBS Órfãos : centenas de discos no estado "Available" (não atrelados a ninguém), cheios de dados inúteis ou completamente vazios, pelos quais você paga o preço cheio do gigabyte provisionado. É comparável a vender seu carro, mas esquecer de cancelar o aluguel da vaga de garagem: o veículo não existe mais, mas a cobrança pelo espaço que ele ocupava continua chegando todo mês na fatura. A situação piora com os Elastic IPs (EIPs) , que possuem uma lógica de cobrança invertida e punitiva. Devido à escassez mundial de endereços IPv4, a AWS não cobra pelo IP enquanto você o utiliza, mas começa a cobrar assim que ele fica ocioso . É como uma "multa por não uso": se você reserva um endereço IP e não o atrela a uma instância em execução, você paga por estar "segurando" um recurso escasso sem necessidade. 4. O Cemitério de Dados no S3 Buckets S3 tendem a virar "cemitérios digitais" onde logs, backups e assets se acumulam indefinidamente. O erro crucial não é guardar os dados, mas a falta de estratégia: manter 100% desse volume na classe S3 Standard , pagando a tarifa mais alta da AWS por arquivos que ninguém acessa há meses. Para entender o prejuízo, imagine o S3 Standard como uma loja no corredor principal de um shopping: o aluguel é caríssimo porque o acesso é imediato e fácil ( baixa latência ). Manter logs de 2022 nessa classe é como alugar essa vitrine premium apenas para estocar caixas de papelão velhas. Dados "frios", que raramente são consultados, não precisam estar à mão em milissegundos; eles podem ficar num armazém mais distante e barato. A solução é o S3 Lifecycle , que automatiza a logística desse "estoque". Primeiro, ele atua na Transição : move automaticamente os dados que envelhecem da "vitrine" (Standard) para o "armazém" ( S3 Glacier ). No Glacier, você paga uma fração do preço, aceitando que o resgate do arquivo leve alguns minutos ou horas (maior latência), o que é aceitável para arquivos de auditoria ou backups antigos. Por fim, o Lifecycle resolve o acúmulo de lixo através da Expiração . Além de mover dados, você configura regras para deletar objetos definitivamente após um período, como remover logs temporários após 7 dias. Isso garante a higiene do ambiente, impedindo que você pague aluguel (seja no shopping ou no armazém) por dados inúteis que não deveriam mais existir. 5. Snapshots: O Colecionador de Backups Fantasmas Backups são a apólice de seguro da sua infraestrutura, mas a facilidade de criar snapshots na AWS gera um comportamento perigoso de acumulação. O erro clássico é configurar uma automação de snapshot diário e definir a retenção para "nunca" ou prazos absurdos como 5 anos. Embora os snapshots sejam incrementais (salvando apenas o que mudou), em bancos de dados transacionais com muita escrita, o volume de dados alterados cresce rápido, e a fatura acompanha. Para visualizar o desperdício, imagine que você compra o jornal do dia para ler as notícias. É útil ter os jornais da última semana na mesa para referência rápida. Mas guardar uma pilha de jornais diários de três anos atrás na sua sala ocupa espaço valioso e custa dinheiro, sendo que a chance de você precisar saber a "cotação do dólar numa terça-feira específica de 2021" é praticamente nula. Você está pagando armazenamento premium por "jornais velhos" que não têm valor de negócio. 6. Licenciamento Comercial (O Custo Invisível) Muitas empresas focam tanto em otimizar CPU e RAM que esquecem o elefante na sala: o custo de software. Ao rodar instâncias com Windows Server ou SQL Server Enterprise na AWS no modelo "License Included", você não paga apenas pela infraestrutura; você paga uma sobretaxa pesada pelo direito de uso do software proprietário. Esse custo é embutido na tarifa por hora e, em máquinas grandes, a licença pode custar mais caro que o próprio hardware. Para ilustrar a desproporção, usar o SQL Server Enterprise para uma aplicação que não utiliza funcionalidades avançadas (como Always On complexo ou compressão de dados específica) é como fretar um jato executivo apenas para ir comprar pão na padaria . O objetivo (armazenar e recuperar dados) é cumprido, mas você está pagando por um veículo de luxo quando uma bicicleta ou um Uber resolveria o problema com a mesma eficiência e uma fração do custo. A primeira camada de solução é a Otimização de Edição . É comum desenvolvedores solicitarem a versão Enterprise por "garantia" ou hábito, sem necessidade técnica real. Uma auditoria simples muitas vezes revela que a versão Standard atende a todos os requisitos da aplicação. Fazer esse downgrade reduz a fatura de licenciamento imediatamente, sem exigir mudanças drásticas na arquitetura ou no código. 7. Dilema Geográfico: Reduzindo a Fatura pela Metade Hospedar aplicações na região sa-east-1 (São Paulo) carrega um ágio pesado: o "Custo Brasil" digital faz com que a infraestrutura local custe, cerca de 50% a mais do que na us-east-1 (N. Virgínia). Migrar workloads para os EUA é, frequentemente, a manobra de FinOps com maior retorno imediato (ROI): você corta a fatura desses recursos praticamente pela metade apenas alterando o CEP do servidor, acessando o mesmo hardware por uma fração do preço. O principal bloqueador costuma ser o medo da LGPD , mas a crença de que a lei exige residência física dos dados no Brasil é um mito . O Artigo 33 permite a transferência internacional para países com proteção adequada (como os EUA), desde que coberto por contratos padrão. A legislação foca na segurança e privacidade do dado, não na sua latitude e longitude geográfica. Quanto à técnica, a latência para a Virgínia (~120ms) é imperceptível para a maioria das aplicações web, sistemas internos e dashboards. A estratégia inteligente é adotar uma região como US East como padrão para maximizar a economia, reservando São Paulo apenas para exceções que realmente exigem resposta em tempo real (como High Frequency Trading), evitando pagar preço de "primeira classe" para cargas de trabalho que rodariam perfeitamente na econômica. 8. Serverless: A Faca de Dois Gumes "Serverless" é computação sem gestão de infraestrutura (como AWS Lambda ou DynamoDB). Diferente de alugar um servidor fixo mensal, aqui você paga apenas pelos milissegundos que seu código executa ou pelo dado que você lê. É como a conta de luz: você só paga se o interruptor estiver ligado. A Estratégia: Para uso esporádico, é imbatível. Mas e para uso constante? Também pode ser uma excelente escolha! Embora a fatura de infraestrutura possa vir mais alta do que em servidores tradicionais, você elimina o trabalho pesado de manutenção. Muitas vezes, é financeiramente mais inteligente pagar um pouco mais para a AWS do que custear horas de engenharia ou contratar uma equipe dedicada apenas para gerenciar servidores, aplicar patches de segurança e configurar escalas. O segredo é olhar para o Custo Total (TCO), e não apenas para a linha de processamento na fatura. 🕵️♂️ FinOps: Engenharia Financeira na Prática FinOps não é apenas sobre "pedir desconto" ou cortar gastos; é a mudança cultural que descentraliza a responsabilidade do custo, empoderando engenheiros a tomar decisões baseadas em dados, não em palpites. Para que essa cultura saia do papel, ela precisa se apoiar em um tripé de governança robusto: a visibilidade granular garantida pelo tageamento correto (saber quem gasta), a segurança operacional monitorada pelo AWS Budgets (saber quando gasta) e a eficiência financeira obtida através dos Modelos de Compra inteligentes (saber como pagar). Sem integrar essas três frentes, a nuvem deixa de ser um acelerador de inovação para se tornar um passivo financeiro descontrolado. 1. TAGs: Sem Etiquetas, Sem Dados 🏷️ No AWS Cost Explorer, uma infraestrutura sem tags opera como uma "caixa preta" financeira: você encara uma fatura de $50.000, mas é incapaz de discernir se o rombo veio de um modelo crítico de Data Science ou de um cluster Kubernetes esquecido por um estagiário. Utiliza tags como custo:centro , app:nome , env e dono no momento dos recursos transformara números genéricos em rastreáveis, permitindo que cada centavo gasto tenha um responsável atrelado, eliminando definitivamente a cultura de que "o custo da nuvem não é problema meu". 2. AWS Budgets e Detecção de Anomalias 🚨 Não espere o fim do mês. Configure o AWS Budgets para alertar quando o custo projetado (forecasted) ultrapassar o limite. Dica: Ative o Cost Anomaly Detection . Ele usa Machine Learning para identificar picos anormais. Exemplo: Um deploy errado fez a cahamada para um Lambda entrar em loop infinito. O Anomaly Detection te avisa em horas, não no fim do mês. 3. Modelos de Compra: O Fim do On-Demand 💸 Operar 100% em On-Demand é pagar voluntariamente um "imposto sobre a falta de planejamento". A maturidade em FinOps exige abandonar o preço de varejo e adotar um mix estratégico: cubra sua carga de trabalho base (aquela que roda 24/7) com Savings Plans , que oferecem descontos de até 72% em troca de fidelidade, e mova cargas tolerantes a interrupções, como processamento de dados e pipelines de CI/CD, para Spot Instances , aproveitando a capacidade ociosa da AWS por até 10% do valor original . Ignorar essa estratégia e manter tudo no On-Demand é uma decisão consciente de desperdiçar orçamento que poderia ser reinvestido em inovação. 🧠 Dev Assina o Código e o Cheque No mundo On-Premise, um código ruim apenas deixava o sistema lento. Na Nuvem, código ineficiente gera uma fatura imediata . A barreira entre Engenharia e Financeiro desapareceu: cada linha de código é uma decisão de compra executada em tempo real. O desenvolvedor não consome apenas CPU, ele consome o orçamento da empresa. Para entender o impacto, veja o preço das más práticas: O Custo da Leitura: Uma query sem " WHERE " ou um Full Table Scan no DynamoDB não é apenas um problema de performance; você está pagando unidades de leitura para ler milhares de linhas inúteis. É como comprar a biblioteca inteira para ler uma única página. O Custo da Ineficiência: Um código com vazamento de memória engana o Auto Scaling . O sistema provisiona 10 servidores para fazer o trabalho de 2, desperdiçando dinheiro para compensar código ruim. O Custo do Ruído: Logs em modo VERBOSE esquecidos em produção são vilões. O CloudWatch cobra caro pela ingestão. Enviar gigabytes de "log de lixo" é literalmente pagar frete aéreo para transportar entulho. A Cultura de Engenharia Consciente de Custos: Estimativa no Refinamento: O custo deve ser debatido antes do código existir. Durante o Refinamento, ao definir a arquitetura, faça a pergunta: "Quais recursos vamos usar e quanto isso vai custar com a volumetria esperada?" . Se a solução técnica custa $1.000 para economizar $50 de esforço manual, ela deve ser vetada ali mesmo. Feedback Loop: O desenvolvedor precisa ver quanto o serviço dele custa. Painéis do Grafana ou Datadog devem mostrar não só a latência da API, mas o custo diário dela. Só existe responsabilidade quando existe consciência do preço. Cerimônia de Custo (FinOps Review): Estabeleça uma reunião recorrente dedicada a olhar o "Extrato da Conta" . O time analisa os custos atuais, investiga picos não planejados da semana anterior e discute ativamente: "Existe alguma oportunidade de desligar recursos ou otimizar este serviço agora?" . É a higiene financeira mantendo o projeto saudável. 🌐 O Mundo Híbrido e Multicloud: Complexidade é Custo Nem tudo precisa ir para a AWS, e nem tudo deve sair do seu Data Center local. A maturidade em nuvem não significa "desligar tudo o que é físico", mas sim saber onde cada peça do jogo custa menos. Empresas podem operam em modelos híbridos estratégicos: O Lugar do Legado (On-Premise): Aquele banco de dados gigante ou mainframe que já está quitado, não cresce mais e roda de forma previsível? Deixe onde está. Migrar esses monstros para a nuvem apenas copiando e colando ("Lift-and-Shift") costuma ser um desastre financeiro. Na nuvem, você paga caro por performance de disco (IOPS) e memória que, no seu servidor físico, já são "gratuitos". O Lugar da Inovação (Nuvem): Seu site, aplicativos móveis e APIs que precisam aguentar milhões de acessos num dia e zero no outro? Leve para a nuvem. Lá você paga pela elasticidade e pelo alcance global que o servidor físico não consegue entregar. Cuidado com a Armadilha Multicloud Muitos gestores caem na tentação de usar AWS, Azure e Google Cloud ao mesmo tempo sob o pretexto de "evitar ficar preso a um fornecedor" (Vendor Lock-in). Na prática, para a maioria das empresas, isso triplica o custo operacional . Você precisará de equipes especialistas em três plataformas diferentes, perderá descontos por volume (diluindo seu gasto) e pagará taxas altíssimas de transferência de dados (Egress) para fazer as nuvens conversarem entre si. Complexidade técnica é, invariavelmente, custo financeiro. Como gerenciar essa infraestrutura sem perder o controle? O uso de ferramentas como Terraform ou OpenTofu . Com elas, criar um servidor não é mais clicar em botões numa tela, mas sim escrever um arquivo de texto (código). Isso habilita a Revisão de Código Financeira : Um desenvolvedor propõe uma mudança no código da infraestrutura. Antes de aprovar, o time revisa num "Pull Request". A pergunta muda de "O código está certo?" para "Por que você alterou a máquina de micro para extra-large ?" . O Code Review de infraestrutura torna-se a primeira e mais barata linha de defesa do FinOps, barrando gastos desnecessários antes mesmo que eles sejam criados. Conclusão: A Nuvem não é um Destino, é um Modelo Econômico Migrar para a nuvem não é apenas trocar de servidor; é adotar um novo paradigma operacional e financeiro. Tratar a AWS como um "datacenter glorificado" é o caminho mais rápido para transformar a inovação em prejuízo: ao fazer isso, você acaba pagando a diária de um hotel cinco estrelas apenas para estocar caixas de papelão que poderiam estar num depósito simples. A virada de chave acontece na cultura. Comece pelo básico bem feito: aplique Tags rigorosamente, automatize a limpeza de recursos e traga o custo para o centro das decisões de arquitetura. Lembre-se que, neste novo mundo, a excelência técnica é inseparável da eficiência financeira: o melhor código não é apenas o que funciona, é o que entrega valor máximo consumindo o mínimo de orçamento.

Report Abuse Ravish Kumar Posted on Jan 11 The Rise of Low-Code and No-Code Development # beginners # productivity # softwaredevelopment # tooling Software development has traditionally been a specialized skill that required years of learning and hands-on experience. Building applications meant writing extensive code, understanding frameworks, and managing complex systems. In recent years, low-code and no-code development platforms have begun to change this reality by making application development more accessible and faster for a wider range of people. Understanding Low-Code and No-Code Development Low-code and no-code platforms are designed to simplify the process of building software. Instead of writing code for every feature, users work with visual interfaces, pre-built components, and automated workflows. No-code platforms allow people with little or no technical background to create functional applications, while low-code platforms offer the flexibility to add custom code when needed. Both approaches focus on reducing complexity while still delivering practical solutions. Why These Platforms Are Gaining Popularity The demand for software has increased dramatically as businesses rely more on digital tools for daily operations. At the same time, there is a shortage of skilled developers, and traditional development methods can be time-consuming and expensive. Low-code and no-code platforms help bridge this gap by enabling faster development with fewer technical resources. Organizations can build applications quickly and adapt them as requirements change. Faster Development and Time-to-Market One of the biggest advantages of low-code and no-code development is the speed at which applications can be created. Traditional development often involves long planning, coding, and testing phases. With visual builders and ready-made features, applications can be developed and deployed in a much shorter time. This faster time-to-market allows businesses to experiment, gather feedback, and improve products without long delays. Empowering Non-Technical Users Low-code and no-code platforms give non-technical users the ability to turn their ideas into working applications. People who understand business workflows or customer needs can design tools that solve real problems without depending entirely on development teams. This reduces bottlenecks, improves collaboration between teams, and encourages innovation across the organization. Where Low-Code and No-Code Work Best These platforms are commonly used for internal tools, workflow automation, dashboards, and simple web or mobile applications. They are particularly useful when speed and ease of development are more important than deep technical customization. However, for highly complex systems that require advanced performance tuning or unique architecture, traditional development approaches are often more suitable. Limitations and Challenges Despite their advantages, low-code and no-code platforms are not without challenges. Customization can be limited, making it difficult to implement highly specific features. Scalability can also become an issue as applications grow. Another concern is vendor dependency, as applications are often tightly linked to the platform on which they are built. Security and compliance must also be carefully considered, especially for applications handling sensitive data. Impact on Professional Developers Rather than replacing developers, low-code and no-code platforms change how developers work. Developers can focus more on complex logic, system architecture, security, and performance, while routine tasks are handled through visual tools. This shift allows development teams to be more efficient and deliver higher-value solutions. The Future of Low-Code and No-Code Development As these platforms continue to evolve, they are becoming more powerful and flexible. The integration of artificial intelligence, automation, and advanced API support is expanding what can be built with low-code and no-code tools. In the future, software development is likely to combine traditional coding with visual development, creating a more balanced and efficient approach. Conclusion The rise of low-code and no-code development represents a major shift in the software industry. By lowering technical barriers and speeding up development, these platforms enable more people to participate in building digital solutions. While they are not suitable for every use case, they have become an important part of modern software development and will continue to shape how applications are built in the years ahead.

Report Abuse Beck_Moulton Posted on Jan 13 Stop Sending Sensitive Data to the Cloud: Build a Local-First Mental Health AI with WebLLM # privacy # typescript # webgpu # webllm In an era where data breaches are common, privacy in Edge AI has moved from a "nice-to-have" to a "must-have," especially in sensitive fields like healthcare. If you've ever worried about your private conversations being used to train a massive corporate model, you're not alone. Today, we are exploring the frontier of Privacy-preserving AI by building a medical Q&A bot that runs entirely on the client side. By leveraging WebLLM , WebGPU , and TVM Unity , we can now execute large language models directly in the browser. This means the dialogue never leaves the user's device, providing a truly decentralized and secure experience. For those looking to scale these types of high-performance implementations, I highly recommend checking out the WellAlly Tech Blog for more production-ready patterns on enterprise-grade AI deployment. The Architecture: Why WebGPU? Traditional AI apps send a request to a server (Python/FastAPI), which queries a GPU (NVIDIA A100), and sends a JSON response back. This "Client-Server" model is the privacy killer. Our "Local-First" approach uses WebGPU , the next-gen graphics API for the web, to tap into the user's hardware directly. graph TD subgraph User_Device [User Browser / Device] A[React UI Layer] -->|Dispatch| B[WebLLM Worker] B -->|Request Execution| C[TVM Unity Runtime] C -->|Compute Kernels| D[WebGPU API] D -->|Inference| E[VRAM / GPU Hardware] E -->|Streaming Text| B B -->|State Update| A end F((Public Internet)) -.->|Static Assets & Model Weights| A F -.->|NO PRIVATE DATA SENT| A Enter fullscreen mode Exit fullscreen mode Prerequisites Before we dive in, ensure you have a browser that supports WebGPU (Chrome 113+ or Edge). Framework : React (Vite template) Language : TypeScript AI Engine : @mlc-ai/web-llm Core Tech : WebGPU & TVM Unity Step 1: Initializing the Engine Running an LLM in a browser requires significant memory management. We use a Web Worker to ensure the UI doesn't freeze while the model is "thinking." // engine.ts import { CreateMLCEngine , MLCEngineConfig } from " @mlc-ai/web-llm " ; const modelId = " Llama-3-8B-Instruct-v0.1-q4f16_1-MLC " ; // Lightweight quantized model export async function initializeEngine ( onProgress : ( p : number ) => void ) { const engine = await CreateMLCEngine ( modelId , { initProgressCallback : ( report ) => { onProgress ( Math . round ( report . progress * 100 )); console . log ( report . text ); }, }); return engine ; } Enter fullscreen mode Exit fullscreen mode Step 2: Creating the Privacy-First Chat Hook In a medical context, the system prompt is critical. We need to instruct the model to behave as a supportive assistant while maintaining strict safety boundaries. // useChat.ts import { useState } from ' react ' ; import { initializeEngine } from ' ./engine ' ; export const useChat = () => { const [ engine , setEngine ] = useState < any > ( null ); const [ messages , setMessages ] = useState < { role : string , content : string }[] > ([]); const startConsultation = async () => { const instance = await initializeEngine (( p ) => console . log ( `Loading: ${ p } %` )); setEngine ( instance ); // Set the System Identity for Mental Health await instance . chat . completions . create ({ messages : [{ role : " system " , content : " You are a private, empathetic mental health assistant. Your goal is to listen and provide support. You do not store data. If a user is in danger, provide emergency resources immediately. " }], }); }; const sendMessage = async ( input : string ) => { const newMessages = [... messages , { role : " user " , content : input }]; setMessages ( newMessages ); const reply = await engine . chat . completions . create ({ messages : newMessages , }); setMessages ([... newMessages , reply . choices [ 0 ]. message ]); }; return { messages , sendMessage , startConsultation }; }; Enter fullscreen mode Exit fullscreen mode Step 3: Optimizing for Performance (TVM Unity) The magic behind WebLLM is TVM Unity , which compiles models into highly optimized WebGPU kernels. This allows us to run models like Llama-3 or Mistral at impressive tokens-per-second on a standard Macbook or high-end Windows laptop. If you are dealing with advanced production scenarios—such as model sharding or custom quantization for specific medical datasets—the team at WellAlly Tech has documented extensive guides on optimizing WebAssembly runtimes for maximum throughput. Step 4: Building the React UI A simple, clean interface is best for mental health applications. We want the user to feel calm and secure. // ChatComponent.tsx import React , { useState } from ' react ' ; import { useChat } from ' ./useChat ' ; export const MentalHealthBot = () => { const { messages , sendMessage , startConsultation } = useChat (); const [ input , setInput ] = useState ( "" ); return ( < div className = "p-6 max-w-2xl mx-auto border rounded-xl shadow-lg bg-white" > < h2 className = "text-2xl font-bold mb-4" > Shielded Mind AI 🛡️ </ h2 > < p className = "text-sm text-gray-500 mb-4" > Status: < span className = "text-green-500" > Local Only (Encrypted by Hardware) </ span ></ p > < div className = "h-96 overflow-y-auto mb-4 p-4 bg-gray-50 rounded" > { messages . map (( m , i ) => ( < div key = { i } className = { `mb-2 ${ m . role === ' user ' ? ' text-blue-600 ' : ' text-gray-800 ' } ` } > < strong > { m . role === ' user ' ? ' You: ' : ' AI: ' } </ strong > { m . content } </ div > )) } </ div > < div className = "flex gap-2" > < input className = "flex-1 border p-2 rounded" value = { input } onChange = { ( e ) => setInput ( e . target . value ) } placeholder = "How are you feeling today?" /> < button onClick = { () => { sendMessage ( input ); setInput ( "" ); } } className = "bg-purple-600 text-white px-4 py-2 rounded hover:bg-purple-700" > Send </ button > </ div > < button onClick = { startConsultation } className = "mt-4 text-xs text-gray-400 underline" > Initialize Secure WebGPU Engine </ button > </ div > ); }; Enter fullscreen mode Exit fullscreen mode Challenges & Solutions Model Size : Downloading a 4GB-8GB model to a browser is the biggest hurdle. Solution : Use IndexedDB caching so the user only downloads the model once. VRAM Limits : Mobile devices may struggle with large context windows. Solution : Implement sliding window attention and aggressive 4-bit quantization. Cold Start : The initial "Loading" phase can take time. Solution : Use a skeleton screen and explain that this process ensures their privacy. Conclusion By moving the "brain" of our AI from the cloud to the user's browser, we've created a psychological safe space that is literally impossible for hackers to intercept at the server level. WebLLM and WebGPU are turning browsers into powerful AI engines. Want to dive deeper into Edge AI security , LLM Quantization , or WebGPU performance tuning ?

Report Abuse Khadijah (Dana Ordalina) Posted on Jan 9 Сине-зеленое развертывание на EKS # eks # aws # bluegreen # programming EKS = Управляемый Kubernetes от Amazon Web Services EKS предоставляет вам: Управляющая плоскость ** Kubernetes** (API-сервер, планировщик). AWS управляет этим за вас. Вам всё ещё необходимо: Рабочие узлы (EC2) → для запуска подов kubectl **→ для связи с кластером **YAML → для указания Kubernetes, что нужно запустить. Очень важная ментальная модель _`Your laptop (kubectl) | v EKS API Server (managed by AWS) | v Worker Nodes (EC2) → Pods → Containers`_ Enter fullscreen mode Exit fullscreen mode Подключаться к узлам по SSH НИКОГДА нельзя. Шаг 1 — Создайте EKS вручную (через консоль AWS, без использования инструментов). 1. Откройте консоль AWS → EKS Выберите регион (например: us-east-1) Нажмите «Создать кластер» . 2. Конфигурация кластера Заполнять только: Имя * : bluegreen-demo * Версия Kubernetes : по умолчанию Роль кластерной службы * : Если AWS отображает её, выберите её. Если нет, нажмите * «Создать роль» (AWS создаст её автоматически). Нажмите Далее 3. Сетевое взаимодействие Использовать значения по умолчанию : VPC по умолчанию Как минимум 2 подсети Доступ к общедоступной конечной точке Нажмите « Создать ». ⏳ Дождитесь активации В этот момент: Kubernetes существует НО пока ничего не может бежать Шаг 2 — Создание рабочих узлов (ЭТО создаст EC2) Зачем нам это нужно Kubernetes размещает поды на узлах . Нет узлов = нет подов. Создать группу узлов Внутри вашего кластера: Перейдите в раздел «Вычисления» → «Добавить группу узлов». Наполнять: Имя: bg-nodes Роль IAM: создать/выбрать роль работника по умолчанию Настройки узла: Тип экземпляра:t3.medium Желательно: 2 Мин.: 2 Макс.: 3 Создать группу узлов → дождаться активации Теперь EC2 существует автоматически. Шаг 3 — Подключите kubectl (так работает DevOps) С вашего ноутбука: aws eks update-kubeconfig \ --region us-east-1 \ --name bluegreen-demo Enter fullscreen mode Exit fullscreen mode Проверять: kubectl get nodes Enter fullscreen mode Exit fullscreen mode Если вы видите узлы → значит, вы соединены. Впредь: Консоль AWS практически неактуальна.

Пользователи видят время простоя Откат происходит медленно. Проблемы, с которыми сталкивался DevOps Простои во время развертывания Пользователи получают ошибки Быстрый откат недоступен. Страх перед развертыванием войск Проблема с Kubernetes решена: - Капсулы - Услуги - Самоисцеление Однако стратегия развертывания определяет, как будет перемещаться трафик. Именно поэтому * существуют стратегии развертывания * . Что такое сине-зеленая стратегия (в простом виде)? Сине-зеленый = две версии, работающие одновременно. Синий → текущее производство Зеленый → новая версия, протестирована Транспортный поток резко меняет направление движения. Отсутствие частичного трафика. Отсутствие замедления развертывания.

Our "Local-First" approach uses WebGPU , the next-gen graphics API for the web, to tap into the user's hardware directly. graph TD subgraph User_Device [User Browser / Device] A[React UI Layer] -->|Dispatch| B[WebLLM Worker] B -->|Request Execution| C[TVM Unity Runtime] C -->|Compute Kernels| D[WebGPU API] D -->|Inference| E[VRAM / GPU Hardware] E -->|Streaming Text| B B -->|State Update| A end F((Public Internet)) -.->|Static Assets & Model Weights| A F -.->|NO PRIVATE DATA SENT| A Enter fullscreen mode Exit fullscreen mode Prerequisites Before we dive in, ensure you have a browser that supports WebGPU (Chrome 113+ or Edge). Framework : React (Vite template) Language : TypeScript AI Engine : @mlc-ai/web-llm Core Tech : WebGPU & TVM Unity Step 1: Initializing the Engine Running an LLM in a browser requires significant memory management. We use a Web Worker to ensure the UI doesn't freeze while the model is "thinking." // engine.ts import { CreateMLCEngine , MLCEngineConfig } from " @mlc-ai/web-llm " ; const modelId = " Llama-3-8B-Instruct-v0.1-q4f16_1-MLC " ; // Lightweight quantized model export async function initializeEngine ( onProgress : ( p : number ) => void ) { const engine = await CreateMLCEngine ( modelId , { initProgressCallback : ( report ) => { onProgress ( Math . round ( report . progress * 100 )); console . log ( report . text ); }, }); return engine ; } Enter fullscreen mode Exit fullscreen mode Step 2: Creating the Privacy-First Chat Hook In a medical context, the system prompt is critical. We need to instruct the model to behave as a supportive assistant while maintaining strict safety boundaries. // useChat.ts import { useState } from ' react ' ; import { initializeEngine } from ' ./engine ' ; export const useChat = () => { const [ engine , setEngine ] = useState < any > ( null ); const [ messages , setMessages ] = useState < { role : string , content : string }[] > ([]); const startConsultation = async () => { const instance = await initializeEngine (( p ) => console . log ( `Loading: ${ p } %` )); setEngine ( instance ); // Set the System Identity for Mental Health await instance . chat . completions . create ({ messages : [{ role : " system " , content : " You are a private, empathetic mental health assistant. Your goal is to listen and provide support. You do not store data. If a user is in danger, provide emergency resources immediately. " }], }); }; const sendMessage = async ( input : string ) => { const newMessages = [... messages , { role : " user " , content : input }]; setMessages ( newMessages ); const reply = await engine . chat . completions . create ({ messages : newMessages , }); setMessages ([... newMessages , reply . choices [ 0 ]. message ]); }; return { messages , sendMessage , startConsultation }; }; Enter fullscreen mode Exit fullscreen mode Step 3: Optimizing for Performance (TVM Unity) The magic behind WebLLM is TVM Unity , which compiles models into highly optimized WebGPU kernels. This allows us to run models like Llama-3 or Mistral at impressive tokens-per-second on a standard Macbook or high-end Windows laptop. If you are dealing with advanced production scenarios—such as model sharding or custom quantization for specific medical datasets—the team at WellAlly Tech has documented extensive guides on optimizing WebAssembly runtimes for maximum throughput. Step 4: Building the React UI A simple, clean interface is best for mental health applications. We want the user to feel calm and secure. // ChatComponent.tsx import React , { useState } from ' react ' ; import { useChat } from ' ./useChat ' ; export const MentalHealthBot = () => { const { messages , sendMessage , startConsultation } = useChat (); const [ input , setInput ] = useState ( "" ); return ( < div className = "p-6 max-w-2xl mx-auto border rounded-xl shadow-lg bg-white" > < h2 className = "text-2xl font-bold mb-4" > Shielded Mind AI 🛡️ </ h2 > < p className = "text-sm text-gray-500 mb-4" > Status: < span className = "text-green-500" > Local Only (Encrypted by Hardware) </ span ></ p > < div className = "h-96 overflow-y-auto mb-4 p-4 bg-gray-50 rounded" > { messages . map (( m , i ) => ( < div key = { i } className = { `mb-2 ${ m . role === ' user ' ? ' text-blue-600 ' : ' text-gray-800 ' } ` } > < strong > { m . role === ' user ' ? ' You: ' : ' AI: ' } </ strong > { m . content } </ div > )) } </ div > < div className = "flex gap-2" > < input className = "flex-1 border p-2 rounded" value = { input } onChange = { ( e ) => setInput ( e . target . value ) } placeholder = "How are you feeling today?" /> < button onClick = { () => { sendMessage ( input ); setInput ( "" ); } } className = "bg-purple-600 text-white px-4 py-2 rounded hover:bg-purple-700" > Send </ button > </ div > < button onClick = { startConsultation } className = "mt-4 text-xs text-gray-400 underline" > Initialize Secure WebGPU Engine </ button > </ div > ); }; Enter fullscreen mode Exit fullscreen mode Challenges & Solutions Model Size : Downloading a 4GB-8GB model to a browser is the biggest hurdle. Solution : Use IndexedDB caching so the user only downloads the model once. VRAM Limits : Mobile devices may struggle with large context windows. Solution : Implement sliding window attention and aggressive 4-bit quantization. Cold Start : The initial "Loading" phase can take time. Solution : Use a skeleton screen and explain that this process ensures their privacy. Conclusion By moving the "brain" of our AI from the cloud to the user's browser, we've created a psychological safe space that is literally impossible for hackers to intercept at the server level. WebLLM and WebGPU are turning browsers into powerful AI engines. Want to dive deeper into Edge AI security , LLM Quantization , or WebGPU performance tuning ?

We started with the barter system , trading goods directly, which was inefficient. We moved to commodity money like gold and salt, then to fiat money (USD, EUR) backed by governments, and eventually to digital banking. But in 2009, Bitcoin emerged as the first decentralized, borderless, and scarce digital currency, removing the need for central authorities. In this article, we’ll break down the technical fundamentals of Bitcoin, from the whitepaper to the architecture of a block. The Vision: The 2008 Whitepaper Satoshi Nakamoto’s whitepaper introduced a peer-to-peer digital currency that solved the double-spending problem using Proof-of-Work (PoW) . Core Principles Fixed Supply: There will never be more than 21 million BTC . Decentralization: No single authority controls the network. Immutability: Once a transaction is on the blockchain ledger, it cannot be altered. Censorship Resistance: Anyone can transact; no one can be blocked. Under the Hood: Block Architecture A blockchain is essentially a timestamped chain of blocks. Think of a block like a "page" in a ledger. Structure of a Block Every block contains three main components: Block Header: Metadata about the block. Transaction Counter: The number of transactions included. Transactions: The actual list of payments. The Block Header The header is critical for mining and validation. It includes: Version: The rules the block follows. Previous Block Hash: The link to the previous block (creating the "chain"). Merkle Root: A summary of all transactions. Timestamp: When the block was mined. Difficulty Target (nBits): Defines how hard it is to mine the block. Nonce: The variable number miners change to solve the cryptographic puzzle. Data Structures: Merkle Trees & Roots Bitcoin uses Merkle Trees (a type of binary tree) to verify data efficiently. The Merkle Tree: Hashes every transaction, pairs them up, and hashes them again until only one hash remains. The Merkle Root: This single "root" hash acts as a fingerprint for the entire block. Why is this useful? It allows for Simplified Payment Verification (SPV) . A user can verify a specific transaction existed without downloading the entire blockchain history. If even one bit of a transaction changes, the Merkle Root changes completely. Consensus: Proof-of-Work (PoW) How does the network agree on the truth? Through mining. Miners collect transactions. They compete to solve a cryptographic puzzle by adjusting the Nonce . The winner gets the block reward (new BTC + transaction fees). While secure and decentralized, PoW is energy-intensive and has limited scalability. Scaling & Evolution The Rise of Altcoins Following Bitcoin, "1st Gen" altcoins emerged. Most were forks of Bitcoin with minor tweaks: Litecoin: Faster block times. Namecoin: Decentralized DNS. Ethereum: Eventually introduced smart contracts, moving beyond simple currency. The Lightning Network (Layer 2) Bitcoin processes only ~7 transactions per second. To solve this, the Lightning Network was built as a Layer 2 solution. How it works: Users open payment channels and transact off-chain instantly and cheaply. Settlement: Only the final balances are recorded on the main blockchain. This enables fast micropayments, though it comes with challenges like routing complexity and liquidity constraints. Conclusion Bitcoin revolutionized money by combining cryptography, game theory, and distributed systems. Understanding these fundamentals—Merkle trees, block headers, and consensus mechanisms—is the first step to mastering the wider Web3 landscape.

Report Abuse Spubhi Posted on Jan 5 Why HMAC Is the Right Choice for Webhook Security (and Why Spubhi Makes It Simple) # security # backend # api Webhooks are one of the most common integration patterns today. They’re also one of the easiest places to make security mistakes. In this post, I’ll focus on why HMAC is a better approach for securing webhooks and how Spubhi keeps the implementation simple and predictable. This is not a comparison-heavy or theory-heavy article — it’s about practical implementation and reliability. The Core Problem with Webhook Security A webhook endpoint is publicly accessible by design. That means anyone can send a request to it unless you validate the sender. The real challenge is not adding authentication, but ensuring that: The request was not modified The sender actually knows a shared secret The validation works reliably across different clients and platforms This is where many webhook implementations break down. Why HMAC Works Well for Webhooks HMAC (Hash-based Message Authentication Code) solves a very specific problem: verifying both authenticity and integrity of a request. When using HMAC: The sender signs the raw request body using a shared secret The receiver independently generates the same signature If the signatures match, the request is trusted No secrets are sent over the wire. Only a signature is transmitted. This has a few important implications: 1. No secret exposure Unlike tokens or passwords, the shared secret is never transmitted in the request. 2. Payload integrity is guaranteed If even one character in the request body changes, the signature validation fails. 3. Stateless validation The server does not need to store sessions or tokens per request. It only needs the shared secret and the incoming payload. 4. Language-agnostic HMAC works the same way in Java, Node.js, Python, Go, or any other language. This makes it ideal for webhook-based systems. Common HMAC Implementation Pitfalls Most HMAC failures don’t come from cryptography — they come from inconsistencies. Some common issues: Signing parsed JSON instead of the raw body Different JSON serialization on sender and receiver Header mismatches or late header injection Async signing issues in tools like Postman A reliable HMAC implementation must: Use the exact raw request body Normalize the payload consistently Use a predictable header for the signature Validate before any business logic executes Why Spubhi Keeps HMAC Simple Spubhi was designed with webhook security as a first-class concern. Here’s what Spubhi does differently: 1. Raw body handling is explicit Spubhi validates HMAC against the actual incoming payload, not a re-serialized version. This avoids subtle mismatches that break signature verification. 2. Header-based authentication only Spubhi expects the HMAC signature in a single, clear header: X-SPUBHI-SECRET No ambiguity. No hidden behavior. 3. No encoding or decoding of secrets Secrets are treated as-is. There’s no unnecessary base64 wrapping or transformation. What you sign on the client is exactly what Spubhi verifies on the server. 4. Authentication happens before flow execution If authentication fails, the request is rejected immediately. No partial execution, no side effects. This makes webhook behavior predictable and safe. Minimal Client-Side HMAC Example // Normalize JSON exactly like your current logic const body = JSON.stringify(JSON.parse(pm.request.body.raw)); // HMAC secret const secret = "hmac_Qv33h2Yp7SpLwl7mQ8geU7R8SrfRZ27BpX5j0tHM"; // Encode inputs const encoder = new TextEncoder(); const keyData = encoder.encode(secret); const bodyData = encoder.encode(body); // Generate HMAC-SHA-256 crypto.subtle.importKey( "raw", keyData, { name: "HMAC", hash: "SHA-512" }, false, ["sign"] ).then(key => { return crypto.subtle.sign("HMAC", key, bodyData); }).then(signature => { const hmac = Array.from(new Uint8Array(signature)) .map(b => b.toString(16).padStart(2, "0")) .join(""); // SAME header name you already use pm.request.headers.upsert({ key: "X-SPUBHI-SECRET", value: hmac }); }); Enter fullscreen mode Exit fullscreen mode That’s it. No SDKs. No custom formats. No hidden transformations. ** Minimal Server-Side Validation Logic** On the server: Read the raw request body Generate HMAC using the same secret Compare it with the incoming header Reject if it doesn’t match Simple logic — easy to audit, easy to debug. Final Thoughts Webhook security doesn’t need to be complex — it needs to be correct and consistent. HMAC works well because it: Protects payload integrity Avoids secret exposure Scales without state Works across platforms Spubhi keeps this model simple by: Avoiding magic Enforcing clear boundaries Treating authentication as a first step, not an afterthought If you’re building webhook-driven integrations, HMAC done right is enough — and simplicity is what makes it reliable. webhooks apissecurity hmac backend integration Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Khadijah (Dana Ordalina) Posted on Jan 9 Сине-зеленое развертывание на EKS # eks # aws # bluegreen # programming EKS = Управляемый Kubernetes от Amazon Web Services EKS предоставляет вам: Управляющая плоскость ** Kubernetes** (API-сервер, планировщик). AWS управляет этим за вас. Вам всё ещё необходимо: Рабочие узлы (EC2) → для запуска подов kubectl **→ для связи с кластером **YAML → для указания Kubernetes, что нужно запустить. Очень важная ментальная модель _`Your laptop (kubectl) | v EKS API Server (managed by AWS) | v Worker Nodes (EC2) → Pods → Containers`_ Enter fullscreen mode Exit fullscreen mode Подключаться к узлам по SSH НИКОГДА нельзя. Шаг 1 — Создайте EKS вручную (через консоль AWS, без использования инструментов). 1. Откройте консоль AWS → EKS Выберите регион (например: us-east-1) Нажмите «Создать кластер» . 2. Конфигурация кластера Заполнять только: Имя * : bluegreen-demo * Версия Kubernetes : по умолчанию Роль кластерной службы * : Если AWS отображает её, выберите её. Если нет, нажмите * «Создать роль» (AWS создаст её автоматически). Нажмите Далее 3. Сетевое взаимодействие Использовать значения по умолчанию : VPC по умолчанию Как минимум 2 подсети Доступ к общедоступной конечной точке Нажмите « Создать ». ⏳ Дождитесь активации В этот момент: Kubernetes существует НО пока ничего не может бежать Шаг 2 — Создание рабочих узлов (ЭТО создаст EC2) Зачем нам это нужно Kubernetes размещает поды на узлах . Нет узлов = нет подов. Создать группу узлов Внутри вашего кластера: Перейдите в раздел «Вычисления» → «Добавить группу узлов». Наполнять: Имя: bg-nodes Роль IAM: создать/выбрать роль работника по умолчанию Настройки узла: Тип экземпляра:t3.medium Желательно: 2 Мин.: 2 Макс.: 3 Создать группу узлов → дождаться активации Теперь EC2 существует автоматически. Шаг 3 — Подключите kubectl (так работает DevOps) С вашего ноутбука: aws eks update-kubeconfig \ --region us-east-1 \ --name bluegreen-demo Enter fullscreen mode Exit fullscreen mode Проверять: kubectl get nodes Enter fullscreen mode Exit fullscreen mode Если вы видите узлы → значит, вы соединены. Впредь: Консоль AWS практически неактуальна. Всё делается с помощью kubectl Почему существуют стратегии развертывания (ОЧЕНЬ ВАЖНО) До Kubernetes (старый мир) Остановить приложение Развернуть новую версию Запустите приложение снова. Пользователи видят время простоя Откат происходит медленно. Проблемы, с которыми сталкивался DevOps Простои во время развертывания Пользователи получают ошибки Быстрый откат недоступен. Страх перед развертыванием войск Проблема с Kubernetes решена: - Капсулы - Услуги - Самоисцеление Однако стратегия развертывания определяет, как будет перемещаться трафик. Именно поэтому * существуют стратегии развертывания * . Что такое сине-зеленая стратегия (в простом виде)? Сине-зеленый = две версии, работающие одновременно. Синий → текущее производство Зеленый → новая версия, протестирована Транспортный поток резко меняет направление движения. Отсутствие частичного трафика. Отсутствие замедления развертывания. Почему сине-зеленый цвет используется в DevOps Преимущества Отсутствие простоев Мгновенный откат Безопасные релизы Легко понять Предсказуемое поведение Когда DevOps выбирает сине-зеленый подход Критические приложения API Финансовые системы Внутренние платформы Когда неудача обходится дорого Как работает принцип «сине-зеленого» взаимодействия в Kubernetes (простая истина) Kubernetes уже предоставляет нам такой инструмент: 👉 Сервис Решение принимает служба: «Какие модули посещают пользователи?» Сине-зеленый = * изменить селектор услуги * Вот и все.

Report Abuse Sagar Posted on Jan 13 • Originally published at sagarparmarr.hashnode.dev GenX: From Childhood Flipbooks to Premium Scroll Animation # webdev # performance # animation Build buttery-smooth, Apple-style image sequence animations on canvas + the tiny redraw hack that saves up to 80% GPU/battery power Hey there, fellow web dev enthusiasts! 🖐️ Remember those childhood flipbooks where you'd scribble a stick figure on the corner of your notebook pages, flip through them furiously, and suddenly – bam – your doodle was dancing? That's the nostalgic spark behind one of the coolest tricks in modern web design: image sequence animations . You've seen them on slick landing pages – those buttery-smooth, scroll-driven "videos" that feel alive as you navigate the site. But here's the plot twist: they're not videos at all . They're just a clever stack of images, orchestrated like a symphony on a <canvas> element. In this post, we're diving into how these animations work, why they're a game-changer for interactive storytelling, and – drumroll please 🥁 – a tiny optimization that stops your user's device from chugging power like it's training for a marathon. Let's flip the page and get started! ✨ Classic flipbook magic – the inspiration behind modern web wizardry Quick access (want to play right away?) → Live Demo → Full source code on GitHub Now let's get into how this magic actually works... Chapter 1: The Flipbook Reborn – What Is Image Sequence Animation? Picture this: You're on a high-end e-commerce site, scrolling down a product page. As your finger glides, a 3D model spins seamlessly, or a background scene morphs from day to night. It looks like high-def video, but peek at the network tab – no MP4 in sight . Instead, it's a barrage of optimized images (usually 100–200 WebP files) doing the heavy lifting. At its core, image sequence animation is digital flipbook wizardry : Export a video/animation as individual frames Preload them into memory as HTMLImageElement objects Drive playback with scroll position (0% = frame 1, 100% = last frame) Render the right frame on <canvas> Why choose this over <video> ? 🎮 Total control — perfect sync with scroll, hover, etc. ⚡ Lightweight hosting — images cache beautifully on CDNs, compress with WebP/AVIF 😅 No encoding drama — skip codecs, bitrates, and cross-browser video nightmares But every hero has a weakness: lots of network requests + heavy repainting = GPU sweat & battery drain on big/retina screens. We'll fix that soon. Smooth scroll-triggered image sequence in action Chapter 2: Behind the Curtain – How the Magic Happens (With Code!) Here's the typical flow in a React-ish world (pseudocode – adapt to vanilla/Vue/Svelte/whatever you love): // React-style pseudocode – hook it up to your scroll listener! const FRAME_COUNT = 192 ; // Your total frames const targetFrameRef = useRef ( 0 ); // Scroll-driven goal const currentFrameRef = useRef ( 0 ); // Current position const rafRef = useRef < number | null > ( null ); // Update target on scroll (progress: 0-1) function onScrollChange ( progress : number ) { const nextTarget = Math . round ( progress * ( FRAME_COUNT - 1 )); targetFrameRef . current = Math . clamp ( nextTarget , 0 , FRAME_COUNT - 1 ); // Assuming a clamp util } // The animation loop: Lerp and draw useEffect (() => { const tick = () => { const curr = currentFrameRef . current ; const target = targetFrameRef . current ; const diff = target - curr ; const step = Math . abs ( diff ) < 0.001 ? 0 : diff * 0.2 ; // Close the gap by 20% each frame const next = step === 0 ? target : curr + step ; currentFrameRef . current = next ; drawFrame ( Math . round ( next )); // Render the frame rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => { if ( rafRef . current ) cancelAnimationFrame ( rafRef . current ); }; }, []); function drawFrame ( index : number ) { const ctx = canvasRef . current ?. getContext ( ' 2d ' ); if ( ! ctx ) return ; // Clear, fill background, and draw image with contain-fit const img = preloadedImages [ index ]; ctx . clearRect ( 0 , 0 , canvas . width , canvas . height ); // ...aspect ratio calculations and drawImage() here... } Enter fullscreen mode Exit fullscreen mode Elegant, right? But here's the villain... The Plot Twist: Idle Repaints = Battery Vampires 🧛♂️ When users pause to read copy or admire the product, that requestAnimationFrame loop keeps churning 60 times per second … redrawing the exact same frame over and over. On high-DPI/4K retina screens? → Massive canvas clears → Repeated image scaling & smoothing → Constant GPU compositing The result: laptop fans kick into overdrive, the device heats up, and battery life tanks fast. I've seen (and measured) this in real projects — idle GPU/CPU spikes that turn a "premium" experience into a power hog. Time for the hero upgrade! Here are real before/after screenshots from my own testing using Chrome DevTools with Frame Rendering Stats enabled (GPU memory + frame rate overlay visible): Before: ~15.6 MB GPU idle After: ~2.4 MB GPU idle Before Optimization After Optimization Idle state with constant repaints – 15.6 MB GPU memory used Idle state post-hack – only 2.4 MB GPU memory used See the difference? Before : ~15.6 MB GPU memory in idle → heavy, wasteful repainting After : ~2.4 MB GPU memory → zen-like efficiency This tiny check eliminates redundant drawImage() calls and can drop idle GPU usage by up to 80% in heavy canvas scenarios (your mileage may vary based on resolution, DPR, and image size). Pro tip: Enable Paint flashing (green highlights) + Frame Rendering Stats in DevTools → scroll a bit, then pause. Watch the green flashes disappear and GPU stats stabilize after applying the fix. Battery saved = happier users + longer sessions 🌍⚡ Chapter 3: The Hero's Hack – Redraw Only When It Matters Super simple fix: track the last drawn frame index and skip drawImage() if nothing changed. useEffect (() => { let prevFrameIndex = Math . round ( currentFrameRef . current ); const tick = () => { // ... same lerp logic ... currentFrameRef . current = next ; const nextFrameIndex = Math . round ( next ); // ★ The magic line ★ if ( nextFrameIndex !== prevFrameIndex ) { drawFrame ( nextFrameIndex ); prevFrameIndex = nextFrameIndex ; } rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => cancelAnimationFrame ( rafRef . current ! ); }, []); Enter fullscreen mode Exit fullscreen mode Why this feels like a superpower Scrolling → still buttery-smooth (draws only when needed) Idle → zen mode (just cheap math, no GPU pain) Real-world wins → up to 80% less idle GPU usage in my tests Pro tip: Use Paint Flashing + Performance tab in DevTools to see the difference yourself. Try it yourself! Here's a minimal, production-ready demo you can fork and play with: → Live Demo → Full source code on GitHub Extra Twists: Level Up Your Animation Game ⚙️ DPR Clamp → cap devicePixelRatio at 2 🖼️ Smart contain-fit drawing (calculate once) 🚀 WebP/AVIF + CDN caching 👀 IntersectionObserver + document.hidden → pause when out of view 🔼 Smart preloading → prioritize first visible frames The Grand Finale: Flipbooks for the Future Image sequence animations are the unsung heroes of immersive web experiences – turning static pages into interactive stories without video baggage . With this tiny redraw check, you're building cool and efficient experiences. Your users (and their batteries) will thank you. Got questions, your own hacks, or want to share a project?

Report Abuse Samuel Ochaba Posted on Jan 8 You Know Python Basics—Now Let's Build Something Real # python # gamedev # beginners # programming Who this is for: You've completed a Python basics course or tutorial. You understand variables, loops, conditionals, and strings. But you haven't built anything real yet. This project is specifically for that stage. You've learned variables, loops, conditionals, and string methods. Each concept made sense in isolation. But when you stared at a blank file and tried to build something... nothing came together. This is the gap between knowing syntax and actually programming . I just open-sourced a project specifically designed to bridge that gap: a text adventure game that combines all those foundational concepts into one playable program. Repo: github.com/samuel-ochaba-dev/zero-to-ai-engineer-projects What You'll Practice This isn't just another tutorial—it's a consolidation project. Every Python basic you've learned has a job: Concept How It's Used Variables & Data Types Game state, rooms, player info Dictionaries Nested data for the game world Operators Health checks, item membership String Methods .strip() , .lower() , .split() , .join() User Input Interactive input() game loop Conditionals if-elif-else and match/case for commands While Loops Main game loop For Loops Iterating inventory with enumerate() Type Hints Self-documenting function signatures The point isn't to learn new syntax. The point is to combine concepts you already know. How to Get the Most from This Don't just run the code. That's the mistake most people make with learning projects. Instead: 1. Read the code without running it first Trace through the main loop. Predict what happens when you type go north or take torch . Then run it to check your mental model. 2. Break something intentionally Remove a line. Change a condition. See what error you get. This teaches you what each piece is actually doing. 3. Extend it The repo includes practice exercises: Add a new room with items Implement a locked door puzzle (requires a key) Add a scoring system Create new random events Building on existing code is how real projects work. The Pattern You'll Keep Using The main game loop looks like this: while game_running : # Check win/lose conditions # Display current state # Get player input # Process command # Trigger random events Enter fullscreen mode Exit fullscreen mode This pattern—a loop that reads input, processes it, updates state, and displays results—appears everywhere : CLI tools Chat applications AI chatbots (read user message → send to LLM → display response → repeat) Game engines REPLs Once you understand this pattern deeply, you'll recognize it in every interactive program you encounter. Requirements Python 3.10+ (required for match/case syntax) No external dependencies git clone https://github.com/samuel-ochaba-dev/zero-to-ai-engineer-projects.git cd zero-to-ai-engineer-projects/dungeon-escape-text-adventure-game python3 adventure_game.py Enter fullscreen mode Exit fullscreen mode Sample Gameplay ======================================== DUNGEON ESCAPE ======================================== You wake up in a dark dungeon. Find the exit to escape! Type 'help' for available commands. You are in the Entrance Hall. A dusty entrance with cobwebs covering the walls. A faint light flickers from the north. Exits: north, east Items here: torch Health: 100 | Inventory: empty What do you do? > Enter fullscreen mode Exit fullscreen mode Navigate through rooms, collect items, survive random events, and find the exit. The mental shift from "I know what a while loop is" to "I can use a while loop to build a game loop" is significant. This project is designed to make that shift concrete. Clone it. Break it. Extend it. This is adapted from my upcoming book, Zero to AI Engineer: Python Foundations.

https://reactjs.org/blog/2019/02/06/react-v16.8.0.html#react-dom | React v16.8: The One With Hooks – React Blog We want to hear from you! Take our 2021 Community Survey! This site is no longer updated. Go to react.dev React Docs Tutorial Blog Community v 18.2.0 Languages GitHub React v16.8: The One With Hooks February 06, 2019 by Dan Abramov This blog site has been archived. Go to react.dev/blog to see the recent posts. With React 16.8, React Hooks are available in a stable release! What Are Hooks? Hooks let you use state and other React features without writing a class. You can also build your own Hooks to share reusable stateful logic between components. If you’ve never heard of Hooks before, you might find these resources interesting: Introducing Hooks explains why we’re adding Hooks to React. Hooks at a Glance is a fast-paced overview of the built-in Hooks. Building Your Own Hooks demonstrates code reuse with custom Hooks. Making Sense of React Hooks explores the new possibilities unlocked by Hooks. useHooks.com showcases community-maintained Hooks recipes and demos. You don’t have to learn Hooks right now. Hooks have no breaking changes, and we have no plans to remove classes from React. The Hooks FAQ describes the gradual adoption strategy. No Big Rewrites We don’t recommend rewriting your existing applications to use Hooks overnight. Instead, try using Hooks in some of the new components, and let us know what you think. Code using Hooks will work side by side with existing code using classes. Can I Use Hooks Today? Yes! Starting with 16.8.0, React includes a stable implementation of React Hooks for: React DOM React DOM Server React Test Renderer React Shallow Renderer Note that to enable Hooks, all React packages need to be 16.8.0 or higher . Hooks won’t work if you forget to update, for example, React DOM. React Native will support Hooks in the 0.59 release . Tooling Support React Hooks are now supported by React DevTools. They are also supported in the latest Flow and TypeScript definitions for React. We strongly recommend enabling a new lint rule called eslint-plugin-react-hooks to enforce best practices with Hooks. It will soon be included into Create React App by default. What’s Next We described our plan for the next months in the recently published React Roadmap . Note that React Hooks don’t cover all use cases for classes yet but they’re very close . Currently, only getSnapshotBeforeUpdate() and componentDidCatch() methods don’t have equivalent Hooks APIs, and these lifecycles are relatively uncommon. If you want, you should be able to use Hooks in most of the new code you’re writing. Even while Hooks were in alpha, the React community created many interesting examples and recipes using Hooks for animations, forms, subscriptions, integrating with other libraries, and so on. We’re excited about Hooks because they make code reuse easier, helping you write your components in a simpler way and make great user experiences. We can’t wait to see what you’ll create next! Testing Hooks We have added a new API called ReactTestUtils.act() in this release. It ensures that the behavior in your tests matches what happens in the browser more closely. We recommend to wrap any code rendering and triggering updates to your components into act() calls. Testing libraries can also wrap their APIs with it (for example, react-testing-library ’s render and fireEvent utilities do this). For example, the counter example from this page can be tested like this: import React from 'react' ; import ReactDOM from 'react-dom' ; import { act } from 'react-dom/test-utils' ; import Counter from './Counter' ; let container ; beforeEach ( ( ) => { container = document . createElement ( 'div' ) ; document . body . appendChild ( container ) ; } ) ; afterEach ( ( ) => { document . body . removeChild ( container ) ; container = null ; } ) ; it ( 'can render and update a counter' , ( ) => { // Test first render and effect act ( ( ) => { ReactDOM . render ( < Counter /> , container ) ; } ) ; const button = container . querySelector ( 'button' ) ; const label = container . querySelector ( 'p' ) ; expect ( label . textContent ) . toBe ( 'You clicked 0 times' ) ; expect ( document . title ) . toBe ( 'You clicked 0 times' ) ; // Test second render and effect act ( ( ) => { button . dispatchEvent ( new MouseEvent ( 'click' , { bubbles : true } ) ) ; } ) ; expect ( label . textContent ) . toBe ( 'You clicked 1 times' ) ; expect ( document . title ) . toBe ( 'You clicked 1 times' ) ; } ) ; The calls to act() will also flush the effects inside of them. If you need to test a custom Hook, you can do so by creating a component in your test, and using your Hook from it. Then you can test the component you wrote. To reduce the boilerplate, we recommend using react-testing-library which is designed to encourage writing tests that use your components as the end users do. Thanks We’d like to thank everybody who commented on the Hooks RFC for sharing their feedback. We’ve read all of your comments and made some adjustments to the final API based on them. Installation React React v16.8.0 is available on the npm registry. To install React 16 with Yarn, run: yarn add react@^16.8.0 react-dom@^16.8.0 To install React 16 with npm, run: npm install --save react@^16.8.0 react-dom@^16.8.0 We also provide UMD builds of React via a CDN: < script crossorigin src = " https://unpkg.com/react@16/umd/react.production.min.js " > </ script > < script crossorigin src = " https://unpkg.com/react-dom@16/umd/react-dom.production.min.js " > </ script > Refer to the documentation for detailed installation instructions . ESLint Plugin for React Hooks Note As mentioned above, we strongly recommend using the eslint-plugin-react-hooks lint rule. If you’re using Create React App, instead of manually configuring ESLint you can wait for the next version of react-scripts which will come out shortly and will include this rule. Assuming you already have ESLint installed, run: # npm npm install eslint-plugin-react-hooks --save-dev # yarn yarn add eslint-plugin-react-hooks --dev Then add it to your ESLint configuration: { "plugins" : [ // ... "react-hooks" ] , "rules" : { // ... "react-hooks/rules-of-hooks" : "error" } } Changelog React Add Hooks — a way to use state and other React features without writing a class.

As with all our minor releases , none of the changes break backwards compatibility. If you’re currently using Hooks from an alpha build of React, note that this release does contain some small breaking changes to Hooks. We don’t recommend depending on alphas in production code. We publish them so we can make changes in response to community feedback before the API is stable. Here are all breaking changes to Hooks that have been made since the first alpha release: Remove useMutationEffect . ( @sophiebits in #14336 ) Rename useImperativeMethods to useImperativeHandle .

Report Abuse Sagar Posted on Jan 13 • Originally published at sagarparmarr.hashnode.dev GenX: From Childhood Flipbooks to Premium Scroll Animation # webdev # performance # animation Build buttery-smooth, Apple-style image sequence animations on canvas + the tiny redraw hack that saves up to 80% GPU/battery power Hey there, fellow web dev enthusiasts! 🖐️ Remember those childhood flipbooks where you'd scribble a stick figure on the corner of your notebook pages, flip through them furiously, and suddenly – bam – your doodle was dancing? That's the nostalgic spark behind one of the coolest tricks in modern web design: image sequence animations . You've seen them on slick landing pages – those buttery-smooth, scroll-driven "videos" that feel alive as you navigate the site. But here's the plot twist: they're not videos at all . They're just a clever stack of images, orchestrated like a symphony on a <canvas> element. In this post, we're diving into how these animations work, why they're a game-changer for interactive storytelling, and – drumroll please 🥁 – a tiny optimization that stops your user's device from chugging power like it's training for a marathon. Let's flip the page and get started! ✨ Classic flipbook magic – the inspiration behind modern web wizardry Quick access (want to play right away?) → Live Demo → Full source code on GitHub Now let's get into how this magic actually works... Chapter 1: The Flipbook Reborn – What Is Image Sequence Animation? Picture this: You're on a high-end e-commerce site, scrolling down a product page. As your finger glides, a 3D model spins seamlessly, or a background scene morphs from day to night. It looks like high-def video, but peek at the network tab – no MP4 in sight . Instead, it's a barrage of optimized images (usually 100–200 WebP files) doing the heavy lifting. At its core, image sequence animation is digital flipbook wizardry : Export a video/animation as individual frames Preload them into memory as HTMLImageElement objects Drive playback with scroll position (0% = frame 1, 100% = last frame) Render the right frame on <canvas> Why choose this over <video> ? 🎮 Total control — perfect sync with scroll, hover, etc. ⚡ Lightweight hosting — images cache beautifully on CDNs, compress with WebP/AVIF 😅 No encoding drama — skip codecs, bitrates, and cross-browser video nightmares But every hero has a weakness: lots of network requests + heavy repainting = GPU sweat & battery drain on big/retina screens. We'll fix that soon. Smooth scroll-triggered image sequence in action Chapter 2: Behind the Curtain – How the Magic Happens (With Code!) Here's the typical flow in a React-ish world (pseudocode – adapt to vanilla/Vue/Svelte/whatever you love): // React-style pseudocode – hook it up to your scroll listener! const FRAME_COUNT = 192 ; // Your total frames const targetFrameRef = useRef ( 0 ); // Scroll-driven goal const currentFrameRef = useRef ( 0 ); // Current position const rafRef = useRef < number | null > ( null ); // Update target on scroll (progress: 0-1) function onScrollChange ( progress : number ) { const nextTarget = Math . round ( progress * ( FRAME_COUNT - 1 )); targetFrameRef . current = Math . clamp ( nextTarget , 0 , FRAME_COUNT - 1 ); // Assuming a clamp util } // The animation loop: Lerp and draw useEffect (() => { const tick = () => { const curr = currentFrameRef . current ; const target = targetFrameRef . current ; const diff = target - curr ; const step = Math . abs ( diff ) < 0.001 ? 0 : diff * 0.2 ; // Close the gap by 20% each frame const next = step === 0 ? target : curr + step ; currentFrameRef . current = next ; drawFrame ( Math . round ( next )); // Render the frame rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => { if ( rafRef . current ) cancelAnimationFrame ( rafRef . current ); }; }, []); function drawFrame ( index : number ) { const ctx = canvasRef . current ?. getContext ( ' 2d ' ); if ( ! ctx ) return ; // Clear, fill background, and draw image with contain-fit const img = preloadedImages [ index ]; ctx . clearRect ( 0 , 0 , canvas . width , canvas . height ); // ...aspect ratio calculations and drawImage() here... } Enter fullscreen mode Exit fullscreen mode Elegant, right? But here's the villain... The Plot Twist: Idle Repaints = Battery Vampires 🧛♂️ When users pause to read copy or admire the product, that requestAnimationFrame loop keeps churning 60 times per second … redrawing the exact same frame over and over. On high-DPI/4K retina screens? → Massive canvas clears → Repeated image scaling & smoothing → Constant GPU compositing The result: laptop fans kick into overdrive, the device heats up, and battery life tanks fast. I've seen (and measured) this in real projects — idle GPU/CPU spikes that turn a "premium" experience into a power hog. Time for the hero upgrade! Here are real before/after screenshots from my own testing using Chrome DevTools with Frame Rendering Stats enabled (GPU memory + frame rate overlay visible): Before: ~15.6 MB GPU idle After: ~2.4 MB GPU idle Before Optimization After Optimization Idle state with constant repaints – 15.6 MB GPU memory used Idle state post-hack – only 2.4 MB GPU memory used See the difference? Before : ~15.6 MB GPU memory in idle → heavy, wasteful repainting After : ~2.4 MB GPU memory → zen-like efficiency This tiny check eliminates redundant drawImage() calls and can drop idle GPU usage by up to 80% in heavy canvas scenarios (your mileage may vary based on resolution, DPR, and image size). Pro tip: Enable Paint flashing (green highlights) + Frame Rendering Stats in DevTools → scroll a bit, then pause. Watch the green flashes disappear and GPU stats stabilize after applying the fix.

Report Abuse Flo Posted on Jan 12 I tried to capture system audio in the browser. Here's what I learned. # webdev # javascript # learning # api I'm building LiveSuggest, a real-time AI assistant that listens to your meetings and gives you suggestions as you talk. Simple idea, right? Turns out, capturing audio from a browser tab is... complicated. The good news Chrome and Edge support it. You use getDisplayMedia , the same API for screen sharing, but with an audio option: const stream = await navigator . mediaDevices . getDisplayMedia ({ video : true , audio : { systemAudio : ' include ' } }); Enter fullscreen mode Exit fullscreen mode The user picks a tab to share, checks "Share tab audio", and boom — you get the audio stream. Works great for Zoom, Teams, Meet, whatever runs in a browser tab. The bad news Firefox? Implements getDisplayMedia but completely ignores the audio part. No error, no warning. You just... don't get audio. Safari? Same story. The API exists, audio doesn't. Mobile browsers? None of them support it. iOS, Android, doesn't matter. So if you're building something that needs system audio, you're looking at Chrome/Edge desktop only. That's maybe 60-65% of your potential users. What I ended up doing I detect the browser upfront and show a clear message: "Firefox doesn't support system audio capture for meetings. Use Chrome or Edge for this feature. Microphone capture is still available." No tricks, no workarounds. Just honesty. Users appreciate knowing why something doesn't work rather than wondering if they did something wrong. For Firefox/Safari users, the app falls back to microphone-only mode. It's not ideal for capturing both sides of a conversation, but it's better than nothing. The annoying details A few things that wasted my time so they don't waste yours: You have to request video. Even if you only want audio. video: true is mandatory. I immediately stop the video track after getting the stream, but you can't skip it. The "Share tab audio" checkbox is easy to miss. Chrome shows it in the sharing dialog, but it's not checked by default. If your user doesn't check it, you get a stream with zero audio tracks. No error, just silence. The stream can die anytime. User clicks "Stop sharing" in Chrome's toolbar? Your stream ends. You need to listen for the ended event and handle it gracefully. Was it worth it? Absolutely. For the browsers that support it, capturing tab audio is a game-changer. You can build things that weren't possible before — meeting assistants, live translators, accessibility tools. Just go in knowing that you'll spend time on browser detection and fallbacks. That's the web in 2025. If you're curious about what I built, check out LiveSuggest . And if you've found better workarounds for Firefox/Safari, I'd love to hear about them in the comments.

Report Abuse Sagar Posted on Jan 13 • Originally published at sagarparmarr.hashnode.dev GenX: From Childhood Flipbooks to Premium Scroll Animation # webdev # performance # animation Build buttery-smooth, Apple-style image sequence animations on canvas + the tiny redraw hack that saves up to 80% GPU/battery power Hey there, fellow web dev enthusiasts! 🖐️ Remember those childhood flipbooks where you'd scribble a stick figure on the corner of your notebook pages, flip through them furiously, and suddenly – bam – your doodle was dancing? That's the nostalgic spark behind one of the coolest tricks in modern web design: image sequence animations . You've seen them on slick landing pages – those buttery-smooth, scroll-driven "videos" that feel alive as you navigate the site. But here's the plot twist: they're not videos at all . They're just a clever stack of images, orchestrated like a symphony on a <canvas> element. In this post, we're diving into how these animations work, why they're a game-changer for interactive storytelling, and – drumroll please 🥁 – a tiny optimization that stops your user's device from chugging power like it's training for a marathon. Let's flip the page and get started! ✨ Classic flipbook magic – the inspiration behind modern web wizardry Quick access (want to play right away?) → Live Demo → Full source code on GitHub Now let's get into how this magic actually works... Chapter 1: The Flipbook Reborn – What Is Image Sequence Animation? Picture this: You're on a high-end e-commerce site, scrolling down a product page. As your finger glides, a 3D model spins seamlessly, or a background scene morphs from day to night. It looks like high-def video, but peek at the network tab – no MP4 in sight . Instead, it's a barrage of optimized images (usually 100–200 WebP files) doing the heavy lifting. At its core, image sequence animation is digital flipbook wizardry : Export a video/animation as individual frames Preload them into memory as HTMLImageElement objects Drive playback with scroll position (0% = frame 1, 100% = last frame) Render the right frame on <canvas> Why choose this over <video> ? 🎮 Total control — perfect sync with scroll, hover, etc. ⚡ Lightweight hosting — images cache beautifully on CDNs, compress with WebP/AVIF 😅 No encoding drama — skip codecs, bitrates, and cross-browser video nightmares But every hero has a weakness: lots of network requests + heavy repainting = GPU sweat & battery drain on big/retina screens. We'll fix that soon. Smooth scroll-triggered image sequence in action Chapter 2: Behind the Curtain – How the Magic Happens (With Code!) Here's the typical flow in a React-ish world (pseudocode – adapt to vanilla/Vue/Svelte/whatever you love): // React-style pseudocode – hook it up to your scroll listener! const FRAME_COUNT = 192 ; // Your total frames const targetFrameRef = useRef ( 0 ); // Scroll-driven goal const currentFrameRef = useRef ( 0 ); // Current position const rafRef = useRef < number | null > ( null ); // Update target on scroll (progress: 0-1) function onScrollChange ( progress : number ) { const nextTarget = Math . round ( progress * ( FRAME_COUNT - 1 )); targetFrameRef . current = Math . clamp ( nextTarget , 0 , FRAME_COUNT - 1 ); // Assuming a clamp util } // The animation loop: Lerp and draw useEffect (() => { const tick = () => { const curr = currentFrameRef . current ; const target = targetFrameRef . current ; const diff = target - curr ; const step = Math . abs ( diff ) < 0.001 ? 0 : diff * 0.2 ; // Close the gap by 20% each frame const next = step === 0 ? target : curr + step ; currentFrameRef . current = next ; drawFrame ( Math . round ( next )); // Render the frame rafRef . current = requestAnimationFrame ( tick ); }; rafRef . current = requestAnimationFrame ( tick ); return () => { if ( rafRef . current ) cancelAnimationFrame ( rafRef . current ); }; }, []); function drawFrame ( index : number ) { const ctx = canvasRef . current ?. getContext ( ' 2d ' ); if ( ! ctx ) return ; // Clear, fill background, and draw image with contain-fit const img = preloadedImages [ index ]; ctx . clearRect ( 0 , 0 , canvas . width , canvas . height ); // ...aspect ratio calculations and drawImage() here... } Enter fullscreen mode Exit fullscreen mode Elegant, right? But here's the villain... The Plot Twist: Idle Repaints = Battery Vampires 🧛♂️ When users pause to read copy or admire the product, that requestAnimationFrame loop keeps churning 60 times per second … redrawing the exact same frame over and over. On high-DPI/4K retina screens? → Massive canvas clears → Repeated image scaling & smoothing → Constant GPU compositing The result: laptop fans kick into overdrive, the device heats up, and battery life tanks fast. I've seen (and measured) this in real projects — idle GPU/CPU spikes that turn a "premium" experience into a power hog. Time for the hero upgrade! Here are real before/after screenshots from my own testing using Chrome DevTools with Frame Rendering Stats enabled (GPU memory + frame rate overlay visible): Before: ~15.6 MB GPU idle After: ~2.4 MB GPU idle Before Optimization After Optimization Idle state with constant repaints – 15.6 MB GPU memory used Idle state post-hack – only 2.4 MB GPU memory used See the difference? Before : ~15.6 MB GPU memory in idle → heavy, wasteful repainting After : ~2.4 MB GPU memory → zen-like efficiency This tiny check eliminates redundant drawImage() calls and can drop idle GPU usage by up to 80% in heavy canvas scenarios (your mileage may vary based on resolution, DPR, and image size). Pro tip: Enable Paint flashing (green highlights) + Frame Rendering Stats in DevTools → scroll a bit, then pause. Watch the green flashes disappear and GPU stats stabilize after applying the fix.

https://reactjs.org/blog/2019/02/06/react-v16.8.0.html#eslint-plugin-for-react-hooks | React v16.8: The One With Hooks – React Blog We want to hear from you! Take our 2021 Community Survey! This site is no longer updated. Go to react.dev React Docs Tutorial Blog Community v 18.2.0 Languages GitHub React v16.8: The One With Hooks February 06, 2019 by Dan Abramov This blog site has been archived. Go to react.dev/blog to see the recent posts. With React 16.8, React Hooks are available in a stable release! What Are Hooks? Hooks let you use state and other React features without writing a class. You can also build your own Hooks to share reusable stateful logic between components. If you’ve never heard of Hooks before, you might find these resources interesting: Introducing Hooks explains why we’re adding Hooks to React. Hooks at a Glance is a fast-paced overview of the built-in Hooks. Building Your Own Hooks demonstrates code reuse with custom Hooks. Making Sense of React Hooks explores the new possibilities unlocked by Hooks. useHooks.com showcases community-maintained Hooks recipes and demos. You don’t have to learn Hooks right now. Hooks have no breaking changes, and we have no plans to remove classes from React. The Hooks FAQ describes the gradual adoption strategy. No Big Rewrites We don’t recommend rewriting your existing applications to use Hooks overnight. Instead, try using Hooks in some of the new components, and let us know what you think. Code using Hooks will work side by side with existing code using classes. Can I Use Hooks Today? Yes! Starting with 16.8.0, React includes a stable implementation of React Hooks for: React DOM React DOM Server React Test Renderer React Shallow Renderer Note that to enable Hooks, all React packages need to be 16.8.0 or higher . Hooks won’t work if you forget to update, for example, React DOM. React Native will support Hooks in the 0.59 release . Tooling Support React Hooks are now supported by React DevTools. They are also supported in the latest Flow and TypeScript definitions for React. We strongly recommend enabling a new lint rule called eslint-plugin-react-hooks to enforce best practices with Hooks. It will soon be included into Create React App by default. What’s Next We described our plan for the next months in the recently published React Roadmap . Note that React Hooks don’t cover all use cases for classes yet but they’re very close . Currently, only getSnapshotBeforeUpdate() and componentDidCatch() methods don’t have equivalent Hooks APIs, and these lifecycles are relatively uncommon. If you want, you should be able to use Hooks in most of the new code you’re writing. Even while Hooks were in alpha, the React community created many interesting examples and recipes using Hooks for animations, forms, subscriptions, integrating with other libraries, and so on. We’re excited about Hooks because they make code reuse easier, helping you write your components in a simpler way and make great user experiences. We can’t wait to see what you’ll create next! Testing Hooks We have added a new API called ReactTestUtils.act() in this release. It ensures that the behavior in your tests matches what happens in the browser more closely. We recommend to wrap any code rendering and triggering updates to your components into act() calls. Testing libraries can also wrap their APIs with it (for example, react-testing-library ’s render and fireEvent utilities do this). For example, the counter example from this page can be tested like this: import React from 'react' ; import ReactDOM from 'react-dom' ; import { act } from 'react-dom/test-utils' ; import Counter from './Counter' ; let container ; beforeEach ( ( ) => { container = document . createElement ( 'div' ) ; document . body . appendChild ( container ) ; } ) ; afterEach ( ( ) => { document . body . removeChild ( container ) ; container = null ; } ) ; it ( 'can render and update a counter' , ( ) => { // Test first render and effect act ( ( ) => { ReactDOM . render ( < Counter /> , container ) ; } ) ; const button = container . querySelector ( 'button' ) ; const label = container . querySelector ( 'p' ) ; expect ( label . textContent ) . toBe ( 'You clicked 0 times' ) ; expect ( document . title ) . toBe ( 'You clicked 0 times' ) ; // Test second render and effect act ( ( ) => { button . dispatchEvent ( new MouseEvent ( 'click' , { bubbles : true } ) ) ; } ) ; expect ( label . textContent ) . toBe ( 'You clicked 1 times' ) ; expect ( document . title ) . toBe ( 'You clicked 1 times' ) ; } ) ; The calls to act() will also flush the effects inside of them. If you need to test a custom Hook, you can do so by creating a component in your test, and using your Hook from it. Then you can test the component you wrote. To reduce the boilerplate, we recommend using react-testing-library which is designed to encourage writing tests that use your components as the end users do. Thanks We’d like to thank everybody who commented on the Hooks RFC for sharing their feedback. We’ve read all of your comments and made some adjustments to the final API based on them. Installation React React v16.8.0 is available on the npm registry. To install React 16 with Yarn, run: yarn add react@^16.8.0 react-dom@^16.8.0 To install React 16 with npm, run: npm install --save react@^16.8.0 react-dom@^16.8.0 We also provide UMD builds of React via a CDN: < script crossorigin src = " https://unpkg.com/react@16/umd/react.production.min.js " > </ script > < script crossorigin src = " https://unpkg.com/react-dom@16/umd/react-dom.production.min.js " > </ script > Refer to the documentation for detailed installation instructions . ESLint Plugin for React Hooks Note As mentioned above, we strongly recommend using the eslint-plugin-react-hooks lint rule. If you’re using Create React App, instead of manually configuring ESLint you can wait for the next version of react-scripts which will come out shortly and will include this rule. Assuming you already have ESLint installed, run: # npm npm install eslint-plugin-react-hooks --save-dev # yarn yarn add eslint-plugin-react-hooks --dev Then add it to your ESLint configuration: { "plugins" : [ // ... "react-hooks" ] , "rules" : { // ... "react-hooks/rules-of-hooks" : "error" } } Changelog React Add Hooks — a way to use state and other React features without writing a class.

As with all our minor releases , none of the changes break backwards compatibility. If you’re currently using Hooks from an alpha build of React, note that this release does contain some small breaking changes to Hooks. We don’t recommend depending on alphas in production code. We publish them so we can make changes in response to community feedback before the API is stable. Here are all breaking changes to Hooks that have been made since the first alpha release: Remove useMutationEffect . ( @sophiebits in #14336 ) Rename useImperativeMethods to useImperativeHandle . ( @threepointone in #14565 ) Bail out of rendering on identical values for useState and useReducer Hooks.

Report Abuse Beck_Moulton Posted on Jan 13 Stop Sending Sensitive Data to the Cloud: Build a Local-First Mental Health AI with WebLLM # privacy # typescript # webgpu # webllm In an era where data breaches are common, privacy in Edge AI has moved from a "nice-to-have" to a "must-have," especially in sensitive fields like healthcare. If you've ever worried about your private conversations being used to train a massive corporate model, you're not alone. Today, we are exploring the frontier of Privacy-preserving AI by building a medical Q&A bot that runs entirely on the client side. By leveraging WebLLM , WebGPU , and TVM Unity , we can now execute large language models directly in the browser. This means the dialogue never leaves the user's device, providing a truly decentralized and secure experience. For those looking to scale these types of high-performance implementations, I highly recommend checking out the WellAlly Tech Blog for more production-ready patterns on enterprise-grade AI deployment. The Architecture: Why WebGPU? Traditional AI apps send a request to a server (Python/FastAPI), which queries a GPU (NVIDIA A100), and sends a JSON response back. This "Client-Server" model is the privacy killer. Our "Local-First" approach uses WebGPU , the next-gen graphics API for the web, to tap into the user's hardware directly. graph TD subgraph User_Device [User Browser / Device] A[React UI Layer] -->|Dispatch| B[WebLLM Worker] B -->|Request Execution| C[TVM Unity Runtime] C -->|Compute Kernels| D[WebGPU API] D -->|Inference| E[VRAM / GPU Hardware] E -->|Streaming Text| B B -->|State Update| A end F((Public Internet)) -.->|Static Assets & Model Weights| A F -.->|NO PRIVATE DATA SENT| A Enter fullscreen mode Exit fullscreen mode Prerequisites Before we dive in, ensure you have a browser that supports WebGPU (Chrome 113+ or Edge). Framework : React (Vite template) Language : TypeScript AI Engine : @mlc-ai/web-llm Core Tech : WebGPU & TVM Unity Step 1: Initializing the Engine Running an LLM in a browser requires significant memory management. We use a Web Worker to ensure the UI doesn't freeze while the model is "thinking." // engine.ts import { CreateMLCEngine , MLCEngineConfig } from " @mlc-ai/web-llm " ; const modelId = " Llama-3-8B-Instruct-v0.1-q4f16_1-MLC " ; // Lightweight quantized model export async function initializeEngine ( onProgress : ( p : number ) => void ) { const engine = await CreateMLCEngine ( modelId , { initProgressCallback : ( report ) => { onProgress ( Math . round ( report . progress * 100 )); console . log ( report . text ); }, }); return engine ; } Enter fullscreen mode Exit fullscreen mode Step 2: Creating the Privacy-First Chat Hook In a medical context, the system prompt is critical. We need to instruct the model to behave as a supportive assistant while maintaining strict safety boundaries. // useChat.ts import { useState } from ' react ' ; import { initializeEngine } from ' ./engine ' ; export const useChat = () => { const [ engine , setEngine ] = useState < any > ( null ); const [ messages , setMessages ] = useState < { role : string , content : string }[] > ([]); const startConsultation = async () => { const instance = await initializeEngine (( p ) => console . log ( `Loading: ${ p } %` )); setEngine ( instance ); // Set the System Identity for Mental Health await instance . chat . completions . create ({ messages : [{ role : " system " , content : " You are a private, empathetic mental health assistant. Your goal is to listen and provide support. You do not store data. If a user is in danger, provide emergency resources immediately. " }], }); }; const sendMessage = async ( input : string ) => { const newMessages = [... messages , { role : " user " , content : input }]; setMessages ( newMessages ); const reply = await engine . chat . completions . create ({ messages : newMessages , }); setMessages ([... newMessages , reply . choices [ 0 ]. message ]); }; return { messages , sendMessage , startConsultation }; }; Enter fullscreen mode Exit fullscreen mode Step 3: Optimizing for Performance (TVM Unity) The magic behind WebLLM is TVM Unity , which compiles models into highly optimized WebGPU kernels. This allows us to run models like Llama-3 or Mistral at impressive tokens-per-second on a standard Macbook or high-end Windows laptop. If you are dealing with advanced production scenarios—such as model sharding or custom quantization for specific medical datasets—the team at WellAlly Tech has documented extensive guides on optimizing WebAssembly runtimes for maximum throughput. Step 4: Building the React UI A simple, clean interface is best for mental health applications. We want the user to feel calm and secure. // ChatComponent.tsx import React , { useState } from ' react ' ; import { useChat } from ' ./useChat ' ; export const MentalHealthBot = () => { const { messages , sendMessage , startConsultation } = useChat (); const [ input , setInput ] = useState ( "" ); return ( < div className = "p-6 max-w-2xl mx-auto border rounded-xl shadow-lg bg-white" > < h2 className = "text-2xl font-bold mb-4" > Shielded Mind AI 🛡️ </ h2 > < p className = "text-sm text-gray-500 mb-4" > Status: < span className = "text-green-500" > Local Only (Encrypted by Hardware) </ span ></ p > < div className = "h-96 overflow-y-auto mb-4 p-4 bg-gray-50 rounded" > { messages . map (( m , i ) => ( < div key = { i } className = { `mb-2 ${ m . role === ' user ' ? ' text-blue-600 ' : ' text-gray-800 ' } ` } > < strong > { m . role === ' user ' ? ' You: ' : ' AI: ' } </ strong > { m . content } </ div > )) } </ div > < div className = "flex gap-2" > < input className = "flex-1 border p-2 rounded" value = { input } onChange = { ( e ) => setInput ( e . target . value ) } placeholder = "How are you feeling today?" /> < button onClick = { () => { sendMessage ( input ); setInput ( "" ); } } className = "bg-purple-600 text-white px-4 py-2 rounded hover:bg-purple-700" > Send </ button > </ div > < button onClick = { startConsultation } className = "mt-4 text-xs text-gray-400 underline" > Initialize Secure WebGPU Engine </ button > </ div > ); }; Enter fullscreen mode Exit fullscreen mode Challenges & Solutions Model Size : Downloading a 4GB-8GB model to a browser is the biggest hurdle. Solution : Use IndexedDB caching so the user only downloads the model once. VRAM Limits : Mobile devices may struggle with large context windows. Solution : Implement sliding window attention and aggressive 4-bit quantization. Cold Start : The initial "Loading" phase can take time. Solution : Use a skeleton screen and explain that this process ensures their privacy. Conclusion By moving the "brain" of our AI from the cloud to the user's browser, we've created a psychological safe space that is literally impossible for hackers to intercept at the server level. WebLLM and WebGPU are turning browsers into powerful AI engines. Want to dive deeper into Edge AI security , LLM Quantization , or WebGPU performance tuning ?

Originally published at Perl Weekly 597 Hi there! I hope you had a successful 2022 and you are ready for the next year. I certainly have lots of plans. As always. They are also changing a lot all the time. One of them is a new course I am working on called OSDC - Open Source Development Course . It is a hands-on course that covers git/GitHub/GitLab/Testing/CI using real-world open source projects. It is also not only a plan, I am starting the first session next Sunday. It will be given in Hebrew. For the course I started to collect Open Source projects developed by corporations . There are a few where the product is open source such as Redis and Elastic . There are others where the company shares some of its code as open source such as Netflix, Facebook, or Booking.com. I'd like to ask for your help. Look around at your company and maybe other companies and let me know which one shares projects using an Open Source license. It would help me and the participants of this courses a lot. For the purpose of the course and for my collection the programming languages don't matter. However, if you can also point out Perl-based projects, that would be even better. Then I could feature these projects in the newsletter. Let's start now with one I already found: pakket by Booking.com is an Unopinionated Meta-Packaging System that allows you to manage dependencies. It works by trying to avoid work.

Report Abuse eachampagne Posted on Nov 17, 2025 • Edited on Dec 6, 2025 Garbage Collection # computerscience # performance # programming It’s easy to forget, while working in the abstract in terms of functions and algorithms, that the memory our programs depend on is real . The values we use in our programs actually exist on the hardware at specific addresses. If we don’t keep track of where we’ve stored data, we run the risk of overwriting something important and getting the wrong information when we go to look it up again. On the other hand, if we’re too guarded about protecting our data, even after we’re finished with it, we waste memory that the program could better use on other tasks. Most programming languages today implement garbage collection to automate periodically releasing memory we no longer need. The garbage collector cannot predict exactly which values will be used again by our program, but it can find some that cannot due to no longer having any way to use them, and safely free them. Garbage Collection Algorithms Reference Counting The simplest algorithm is just to keep a count of references to a piece of memory. If the number of references ever reaches zero, that memory can no longer be reached and can be safely disposed of. However, this strategy fails with circular references. If two objects, for example, reference each other, their reference counts with never reach zero, even if they are otherwise inaccessible from the main program. Tracing Tracing (usually mark-and-sweep), is a more sophisticated approach to memory management. Starting from some defined root(s), the garbage collector visits every piece of memory accessible from either the root or its descendants, marking that memory as still reachable. Any memory not traversed is unreachable and is garbage collected. This avoids the problem of circular references “trapping” memory, since the cycle will not be reached from the main memory graph. However, this approach has more overhead than the reference counting strategy. Many garbage collectors reduce the overhead of mark-and-search by having two (or more) “generations” of allocations. The generational hypothesis states that most allocations die young (think how many variables you use once in a for loop and never again), but those that survive are much more likely to survive a long time. Thus, the pool of young allocations (the “nursery”) is garbage collected frequently, while the old (“tenured”) pool is checked less often. It’s possible to combine both strategies in a hybrid collector. For example, Python uses reference counting as its primary algorithm, then uses a mark-and-sweep pass over the (now smaller) pool of allocated memory to find and eliminate circular references. The Downsides of Garbage Collection Of course, the garbage collector itself introduces some overhead. Depending on the implementation, it may bring the program to a halt while it scans and frees data or defragments the remaining memory. It is also impossible to create a perfectly efficient garbage collector due to the inherent uncertainty in which values will be used again. Other Approaches to Memory Management There are alternatives to garbage collection. A few languages, such as C and C++, require the programmer to manage memory manually (although you can add garbage collectors to both languages yourself if you wish), both while allocating memory to new variables and when deciding when to free memory. Manual memory management avoids the overhead of garbage collection, but adds to program complexity, since this now must be handled by the code itself rather than happening in the background. This also gives the programmer many opportunities to make mistakes , from creating floating pointers by freeing too soon to leaking memory by freeing too late or not at all, to say nothing of the difficulty of using pointers themselves. Rust takes a third option and introduces the concept of “ ownership ” – only one variable can own a piece of data at a time, and that data is released as soon as its owner goes out of scope. This eliminates the need for garbage collection at runtime, as well with its associated performance costs. However, the programmer has to keep track of ownership and borrowing of data, which limits how data can be read or changed at certain points of the program. This requires thinking in a different way from other languages, since some familiar patterns simply won’t compile, and increases Rust’s learning curve sharply. Garbage Collection in JavaScript JavaScript follows the majority of programming languages in using a garbage collector. However, the garbage collector itself is implemented and run by the JavaScript engine, not the script we write ourselves, so implementation varies slightly across engines. However, the general principles are the same. Modern JavaScript libraries all use a mark-and-sweep algorithm with the global object as the algorithm’s root. Since I regularly use Firefox and Node, I’ll look at their engines in a bit more detail. SpiderMonkey , the engine used by Firefox, applies the principle of generational collection, dividing allocations into young and old. It attempts to garbage collect incrementally to avoid long pauses, and runs parts of garbage collection in parallel with itself or concurrently with the main thread when possible. The V8 engine’s Orinoco garbage collector , has three generations: nursery, young, and old, and claims (as of 2019) to be a “mostly parallel and concurrent collector with incremental fallback.” V8 also brags about interweaving garbage collection into the idle time between drawing frames when possible, minimizing the time spent forcing JavaScript execution to pause. Based only on these descriptions, V8’s garbage collector seems a bit more advanced, perhaps because V8 used by Chromium-based browsers in addition to Node.js and thus has more support. However, they seem to have independently converged to similar architectures. The serious demands to provide a smooth user experience means that browser-based garbage collectors must be efficient and eliminate as much overhead as possible, because, as the Node guide to tracing garbage collection neatly summarizes, “ when GC is running, your code is not. ” I admit I’ve rather taken memory management for granted, since most of the languages I’ve studied have garbage collectors. I’ve been fascinated by Rust for years but haven’t managed to wrap my head around its ownership and borrowing rules. (Maybe this is the time it will finally click for me.) But if I struggle with memory management when the compiler itself is looking out for me, I’m not sure how I’d fare in a manual memory management scheme without guardrails. So for now, I’m very grateful to garbage collectors everywhere for making my life easier. The Memory Management Reference was invaluable while researching this blog post, in addition to many other engine- and language-specific references (linked throughout the text).

Report Abuse Ajay Shankar Posted on Oct 7, 2025 From Public Risk to Private Security: CloudFront with Internal ALB # cloudsecurity # aws # networksec # soc Exposing an Application Load Balancer (ALB) to the public internet might seem like the simplest way to make applications globally accessible. But each public ALB is essentially an open door, accessible to anyone, including hackers, bots, or misconfigured scripts. Even with firewalls and security groups in place, small human errors can create major vulnerabilities. A misconfigured rule could let unauthorized requests reach your backend, or sensitive APIs might be discovered and exploited. As applications expand across multiple environments, accounts, or regions, keeping track of which ALBs are public becomes a daunting task. Complexity grows, and so does the risk. In short, public ALBs make your infrastructure fragile, risky, and harder to manage. Solution: CloudFront with Internal ALB The best way to mitigate this risk is to use AWS CloudFront in front of an internal ALB. This setup allows global users to access applications securely, while the backend remains completely private inside a VPC. Architecture Overview Deploy Internal ALB in a Private Subnet - The ALB is not reachable from the internet, keeping your backend safe. Configure CloudFront Distribution - CloudFront acts as the global entry point. It connects to the internal ALB via a VPC Endpoint / PrivateLink, ensuring private communication. Implement Security Controls - Security groups allow traffic only from CloudFront IP ranges. Optionally, enable AWS WAF for additional protection against malicious requests. Outcome: Users get fast, global access, and your applications remain private and secure. Conclusion : From a cybersecurity standpoint, exposing an ALB to the public internet introduces unnecessary risks. By using AWS CloudFront with an internal ALB, organizations can minimize the attack surface, ensuring that only validated requests from CloudFront reach the backend.

This requires thinking in a different way from other languages, since some familiar patterns simply won’t compile, and increases Rust’s learning curve sharply. Garbage Collection in JavaScript JavaScript follows the majority of programming languages in using a garbage collector. However, the garbage collector itself is implemented and run by the JavaScript engine, not the script we write ourselves, so implementation varies slightly across engines. However, the general principles are the same. Modern JavaScript libraries all use a mark-and-sweep algorithm with the global object as the algorithm’s root. Since I regularly use Firefox and Node, I’ll look at their engines in a bit more detail. SpiderMonkey , the engine used by Firefox, applies the principle of generational collection, dividing allocations into young and old. It attempts to garbage collect incrementally to avoid long pauses, and runs parts of garbage collection in parallel with itself or concurrently with the main thread when possible. The V8 engine’s Orinoco garbage collector , has three generations: nursery, young, and old, and claims (as of 2019) to be a “mostly parallel and concurrent collector with incremental fallback.” V8 also brags about interweaving garbage collection into the idle time between drawing frames when possible, minimizing the time spent forcing JavaScript execution to pause. Based only on these descriptions, V8’s garbage collector seems a bit more advanced, perhaps because V8 used by Chromium-based browsers in addition to Node.js and thus has more support. However, they seem to have independently converged to similar architectures. The serious demands to provide a smooth user experience means that browser-based garbage collectors must be efficient and eliminate as much overhead as possible, because, as the Node guide to tracing garbage collection neatly summarizes, “ when GC is running, your code is not. ” I admit I’ve rather taken memory management for granted, since most of the languages I’ve studied have garbage collectors. I’ve been fascinated by Rust for years but haven’t managed to wrap my head around its ownership and borrowing rules. (Maybe this is the time it will finally click for me.) But if I struggle with memory management when the compiler itself is looking out for me, I’m not sure how I’d fare in a manual memory management scheme without guardrails. So for now, I’m very grateful to garbage collectors everywhere for making my life easier. The Memory Management Reference was invaluable while researching this blog post, in addition to many other engine- and language-specific references (linked throughout the text).

Report Abuse Samuel Ochaba Posted on Jan 8 You Know Python Basics—Now Let's Build Something Real # python # gamedev # beginners # programming Who this is for: You've completed a Python basics course or tutorial. You understand variables, loops, conditionals, and strings. But you haven't built anything real yet. This project is specifically for that stage. You've learned variables, loops, conditionals, and string methods. Each concept made sense in isolation. But when you stared at a blank file and tried to build something... nothing came together. This is the gap between knowing syntax and actually programming . I just open-sourced a project specifically designed to bridge that gap: a text adventure game that combines all those foundational concepts into one playable program. Repo: github.com/samuel-ochaba-dev/zero-to-ai-engineer-projects What You'll Practice This isn't just another tutorial—it's a consolidation project. Every Python basic you've learned has a job: Concept How It's Used Variables & Data Types Game state, rooms, player info Dictionaries Nested data for the game world Operators Health checks, item membership String Methods .strip() , .lower() , .split() , .join() User Input Interactive input() game loop Conditionals if-elif-else and match/case for commands While Loops Main game loop For Loops Iterating inventory with enumerate() Type Hints Self-documenting function signatures The point isn't to learn new syntax. The point is to combine concepts you already know. How to Get the Most from This Don't just run the code. That's the mistake most people make with learning projects. Instead: 1. Read the code without running it first Trace through the main loop. Predict what happens when you type go north or take torch . Then run it to check your mental model. 2. Break something intentionally Remove a line. Change a condition. See what error you get. This teaches you what each piece is actually doing. 3. Extend it The repo includes practice exercises: Add a new room with items Implement a locked door puzzle (requires a key) Add a scoring system Create new random events Building on existing code is how real projects work. The Pattern You'll Keep Using The main game loop looks like this: while game_running : # Check win/lose conditions # Display current state # Get player input # Process command # Trigger random events Enter fullscreen mode Exit fullscreen mode This pattern—a loop that reads input, processes it, updates state, and displays results—appears everywhere : CLI tools Chat applications AI chatbots (read user message → send to LLM → display response → repeat) Game engines REPLs Once you understand this pattern deeply, you'll recognize it in every interactive program you encounter. Requirements Python 3.10+ (required for match/case syntax) No external dependencies git clone https://github.com/samuel-ochaba-dev/zero-to-ai-engineer-projects.git cd zero-to-ai-engineer-projects/dungeon-escape-text-adventure-game python3 adventure_game.py Enter fullscreen mode Exit fullscreen mode Sample Gameplay ======================================== DUNGEON ESCAPE ======================================== You wake up in a dark dungeon. Find the exit to escape! Type 'help' for available commands. You are in the Entrance Hall. A dusty entrance with cobwebs covering the walls. A faint light flickers from the north. Exits: north, east Items here: torch Health: 100 | Inventory: empty What do you do? > Enter fullscreen mode Exit fullscreen mode Navigate through rooms, collect items, survive random events, and find the exit. The mental shift from "I know what a while loop is" to "I can use a while loop to build a game loop" is significant. This project is designed to make that shift concrete. Clone it. Break it. Extend it. This is adapted from my upcoming book, Zero to AI Engineer: Python Foundations.

Who wins? # webdev # css # javascript # react Introduction In modern React application development, there are many approaches to organizing application styles. One of the popular ways of such an organization is the CSS-in-JS approach (in the article we will use styled-components as the most popular solution) and CSS Modules. In this article, we will try to answer the question: which is better CSS-in-JS or CSS Modules ? So let's get back to basics. When a web page was primarily set for storing textual documentation and didn't include user interactions, properties were introduced to style the content. Over time, the web became more and more popular, sites got bigger, and it became necessary to reuse styles. For these purposes, CSS was invented. Cascading Style Sheets. Cascading plays a very important role in this name. We write styles that lay like a waterfall over the hollows of our document, filling it with colors and highlighting important elements. Time passed, the web became more and more complex, and we are facing the fact that the styles cascade turned into a problem for us. Distributed teams, working on their parts of the system, combining them into reusable modules, assemble an application from pieces, like Dr. Frankenstein, stitching styles into one large canvas, can get the sudden result... Due to the cascade, the styles of module 1 can affect the display of module 3, and module 4 can make changes to the global styles and change the entire display of the application in general. Developers have started to think of solving this problem. Style naming conventions were created to avoid overlaps, such as Yandex's BEM or Atomic CSS. The idea is clear, we operate with names in order to get predictability, but at the same time to prevent repetitions. These approaches were crashed of the rocks of the human factor. Anyway, we have no guarantee that the developer from team A won't use the name from team C. The naming problem can only be solved by assigning a random name to the CSS class. Thus, we get a completely independent CSS set of styles that will be applied to a specific HTML block and we understand for sure that the rest of the system won't be affected in any way. And then 2 approaches came onto the stage to organize our CSS: CSS Modules and CSS-in-JS . Under the hood, having a different technical implementation, and in fact solving the problem of atomicity, reusability, and avoiding side effects when writing CSS. Technically, CSS Modules transforms style names using a hash-based on the filename, path, style name. Styled-components handles styles in JS runtime, adding them as they go to the head HTML section (<head>). Approaches overview Let's see which approach is more optimal for writing a modern web application! Let's imagine we have a basic React application: import React , { Component } from ' react ' ; import ' ./App.css ' ; class App extends Component { render () { return ( < div className = "title" > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode CSS styles of this application: .title { padding : 20px ; background-color : #222 ; text-align : center ; color : white ; font-size : 1.5em ; } Enter fullscreen mode Exit fullscreen mode The dependencies are React 16.14 , react-dom 16.14 Let's try to build this application using webpack using all production optimizations. we've got uglified JS - 129kb separated and minified CSS - 133 bytes The same code in CSS Modules will look like this: import React , { Component } from ' react ' ; import styles from ' ./App.module.css ' ; class App extends Component { render () { return ( < div className = { styles . title } > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 129kb separated and minified CSS - 151 bytes The CSS Modules version will take up a couple of bytes more due to the impossibility of compressing the long generated CSS names. Finally, let's rewrite the same code under styled-components: import React , { Component } from ' react ' ; import styles from ' styled-components ' ; const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ` ; class App extends Component { render () { return ( < Title > React application title </ Title > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 163kb CSS file is missing The more than 30kb difference between CSS Modules and CSS-in-JS (styled-components) is due to styled-components adding extra code to add styles to the <head> part of the HTML document. In this synthetic test, the CSS Modules approach wins, since the build system doesn't add something extra to implement it, except for the changed class name. Styled-components due to technical implementation, adds dependency as well as code for runtime handling and styling of <head>. Now let's take a quick look at the pros and cons of CSS-in-JS / CSS Modules. Pros and cons CSS-in-JS cons The browser won't start interpreting the styles until styled-components has parsed them and added them to the DOM, which slows down rendering. The absence of CSS files means that you cannot cache separate CSS. One of the key downsides is that most libraries don't support this approach and we still can't get rid of CSS. All native JS and jQuery plugins are written without using this approach. Not all React solutions use it. Styles integration problems. When a markup developer prepares a layout for a JS developer, we may forget to transfer something; there will also be difficulty in synchronizing a new version of layout and JS code. We can't use CSS utilities: SCSS, Less, Postcss, stylelint, etc. pros Styles can use JS logic. This reminds me of Expression in IE6, when we could wrap some logic in our styles (Hello, CSS Expressions :) ). const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ${ props => props . secondary && css ` background-color: #fff; color: #000; padding: 10px; font-size: 1em; ` } ` ; Enter fullscreen mode Exit fullscreen mode When developing small modules, it simplifies the connection to the project, since you only need to connect the one independent JS file. It is semantically nicer to use <Title> in a React component than <h1 className={style.title}>. CSS Modules cons To describe global styles, you must use a syntax that does not belong to the CSS specification. :global ( .myclass ) { text-decoration : underline ; } Enter fullscreen mode Exit fullscreen mode Integrating into a project, you need to include styles. Working with typescript, you need to automatically or manually generate interfaces. For these purposes, I use webpack loader: @teamsupercell/typings-for-css-modules-loader pros We work with regular CSS, it makes it possible to use SCSS, Less, Postcss, stylelint, and more. Also, you don't waste time on adapting the CSS to JS. No integration of styles into the code, clean code as result. Almost 100% standardized except for global styles. Conclusion So the fundamental problem with the CSS-in-JS approach is that it's not CSS! This kind of code is harder to maintain if you have a defined person in your team working on markup. Such code will be slower, due to the fact that the CSS rendered into the file is processed in parallel, and the CSS-in-JS cannot be rendered into a separate CSS file. And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on. On the other hand, the CSS-in-JS approach can be a good solution for the Frontend team who deals with both markup and JS, and develops all components from scratch. Also, CSS-in-JS will be useful for modules that integrate into other applications. In my personal opinion, the issue of CSS cascading is overrated. If we are developing a small application or site, with one team, then we are unlikely to encounter a name collision or the difficulty of reusing components. If you faced with this problem, I recommend considering CSS Modules, as, in my opinion, this is a more optimal solution for the above factors. In any case, whatever you choose, write meaningful code and don't get fooled by the hype. Hype will pass, and we all have to live with it. Have great and interesting projects, dear readers!

But i ran into issues with styled components that I wouldn't have had with plain scss. So some things to think about: Styled components is a lot more overhead because all the styled components need to be complied into stylesheets and mounted to the head by javascript which is a blocking language. On SSR styled components get compiled into a ServerStyleSheet that then hydrate the react dom tree in the browser via the context api. So even then the mounting of styles only happens in the browser but the parsing of styles happens on the server - that is still a performance penalty and will slow down the page load. In some cases I had no issues with styled components but as my site grew and in complex cases I couldn't help but feel like it was slower, or didn't load as smoothly... and in a world where every second matters, this was a problem for me. Here is an article doing benchmarks on CSS vs CSS in JS: pustelto.com/blog/css-vs-css-in-js... I use nextjs, it is a pity they do not support component level css and we are forced to use css modules or styled components... where as with Nuxt component level scss is part of the package and you have the option on how you want the sites css to bundled - all in one file, split into their own files and some other nifty options. I hope nextjs sharped up on this.

I've opted to use emotion's css utility exclusively and instructed my team to avoid using any of the styled component features. We've loved it but this was a few years ago. For newer projects I'm going with the css modules design. Also why does anyone care about sass anymore? With css variables and the css nesting module in the specification, you get the best parts of sass with vanilla css. The other features are just overkill for a css-module that should represent a single react component and thus nothing :global . Complicated sass directives and stuff are just overkill. Turn it into a react component and don't make any crazy css systems.

I've been using CSS modules for a short time now and I like it. Allows everything to be nicely compartmentalized. I also like that it gives more freedom to name classes in smaller chunks of CSS code.

"And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on." Not a single thing here is true. SCSS is the original syntax of the package, you can use Stylelint as well. There are a lot more "pros" which are not listed here. By working with JS you are opened to another world. I'll list some more "pros" from the top of my head: consume and validate your theme colors as pure JS object consume state/props and create dynamic CSS out of it you have plugins which can be a live savers in cases like RTL (right to left orientation). Whoever had to support an app/website with RTL will be magically saved by this plugin. You can create custom plugins to fix various problems, or make your own linting in your team project. you don't think about CSS class names and collision. I prefer to be focused on thinking about variable names in my JS only and not spending effort in the CSS as well when you break your visual habits you will realise that's it's easier to have your CSS in your JS file just the way you got used to have your HTML in your JS file (React) In these days CSS has become a monster. You have inheritance, mixins, variables, IF statements, loops etc. Sure they can be useful somewhere but I'm pretty sure that most of you just need to center that div. So in my personal opinion we should strive to keep CSS as simpler as possible (as with everything actually) and I think that Styled Components are kind of pushing you to do exactly that. Don't re-use CSS, re-use components! The only global things you should have are probably just the color theme and animations.

Report Abuse ANIRUDDHA ADAK Posted on Jan 13 From 2AM Debugging to $1000: How I Built My AI-Powered Portfolio # devchallenge # googleaichallenge # portfolio # gemini New Year, New You Portfolio Challenge Submission This is a submission for the New Year, New You Portfolio Challenge Presented by Google AI About Me I'm a final-year B.Tech student who basically made a Faustian deal where I traded sleep for AI knowledge. By day, I'm grinding through multimedia systems, ML algorithms, and cybersecurity concepts. By night (and I mean literally 2 AM), I'm building projects with Python, JavaScript, and whatever Google AI tool I can get my hands on. I've been freelancing, creating content across Dev.to, Twitter, and LinkedIn, building AI-generated video and image content, and competing in every challenge that promises rewards and bragging rights. This challenge? Perfect fit for someone who's been juggling a portfolio refresh for months while being too busy "just starting one more quick AI experiment." What I'm Building My portfolio is my digital middle finger to generic templates. It showcases: AI & ML Projects : Text-to-image generators, text-to-video experiments, and ML models from graphical models to generative AI Web Dev Work : Full-stack projects with clean UI, responsive design, and actual personality Technical Writing : Dev.to blogs, GitHub documentation, and content that doesn't put people to sleep The Real Me : Casual, slightly sarcastic, obsessed with automation, and absolutely fueled by Gemini API documentation and cold coffee I deployed it to Google Cloud Run because (a) it was surprisingly painless, and (b) I wanted to prove that building modern portfolios doesn't require a PhD in DevOps. How I Built It Tech Stack : HTML/CSS/JavaScript on the frontend, Python for any backend logic, and Google Cloud Run for deployment. Google AI Integration : Used Gemini via AI Studio to help brainstorm portfolio copy that sounds natural, not robotic Leveraged Google Cloud Run free tier (because student budget = zero budget) to deploy without crying Experimented with embedding AI-powered features directly into the portfolio to showcase my skills Design Philosophy : Modern, dark-mode friendly, fast, and with enough personality that judges remember me as "that person who cracked jokes in their portfolio" and not just another submission. What I'm Most Proud Of Honesty Over Hype : This portfolio actually represents who I am—a B.Tech student obsessed with AI and shipping things, not some fictional 10x developer who knows every framework AI Integration Done Right : Not just slapping "powered by Gemini" on things; actually using AI tools meaningfully in both the building and the presentation Speed & UX : The site loads fast, looks good on mobile, and doesn't throw 50 pop-ups at visitors The Copy : Every project description feels like I wrote it while caffeinated at 3 AM (because I did), but it's still clear and compelling Why I'm Here Honestly? The money's nice. The feedback from the Google AI team? Even better. But mostly, I'm here because building is what makes me feel alive, and this challenge forced me to stop procrastinating and actually deploy the portfolio I've been planning since November. If I win, that's $1000 toward my next adventure (probably server costs for some overambitious AI project). If I don't, I still have a portfolio I'm genuinely proud of, and that's not a small thing. Let's see if the judges appreciate my blend of technical skill and comedic timing. 🚀 Portfolio Note to readers : To embed your live Cloud Run portfolio here, follow the Cloud Run embedding guide and use the label --labels dev-tutorial=devnewyear2026 during deployment. Your portfolio URL will appear live in this post. My portfolio is currently live and showcases all the projects, skills, and personality described above.

Report Abuse Trishan Fernando Posted on Oct 8, 2025 Comet Browser : Perplexity’s Thinking Browser # webdev # ai # learning # productivity We’ve all been living in browsers for years now — Chrome, Edge, Safari… they all kinda feel the same. Open tabs, search things, maybe add a couple of extensions, repeat. Useful? Sure. Fun? Not so much. And then Comet from Perplexity. And honestly, it doesn’t just feel like another browser — it feels like a new class. It’s as if having an AI buddy floating right amidst your browsing life. Get Early Access & Download Comet Comet is not available for free it needs the 200$ Perplexity Subscription with an invitation. But you can get it through partners for free if you are a university Student. Get Early Access With Your University Email.Use your University email to Verify that you are a student Get Early Access & Download Comet What’s the excitement about? Comet isn’t all about “opening sites faster.” It’s about doing things with your browser instead of just staring at it. Got 10 tabs open doing research? Tell Comet to summarize them into one neat note. Shopping for a laptop? Have it search deals on websites and show you the top choices. Writing an email? Cross out a couple of pages and voila — it writes something that even sounds logical. Doing a project? Keep your tabs + notes + AI summaries all bundled up in a neat space you can return to. It is like the distinction between you driving a vehicle and having a vehicle that helps you drive, monitors your schedule, and maybe even helps you save money on fuel in the bargain. What people are saying I’ve been skimming through Reddit, X, and LinkedIn, and the vibe is clear: folks are hyped. People call it “futuristic,” “the only browser that actually boosts productivity,” and “perfect for research.” Students, writers, and even devs juggling docs love that it cuts down tab chaos. Of course, there’s a catch — some grumblings that it’s invite-only for certain plans, and pricing debates. Totally fair. But that’s what you get when you’re not building another browser, you’re trying to rethink how we browse period. One heads-up though ??? AI browsers are new territory. Security researchers raise the alarms for dangers like nefarious sites trying to trick the AI into making bad decisions (autofilling data, risky clicks, etc.). So yeah — Comet does have a future vibe to it, but maybe don’t fling your banking login data at it just yet. Why I think this matters Comet is the first browser I’ve used that truly seems to be built for the way we actually work in 2025: multitasking, info overload, constant context-switching. Instead of just allowing us to have more tabs, it processes them. And for real? Once you get a taste of it, browsing with a “regular” browser again feels… kinda like using a Nokia brick phone once you’ve had a smartphone. And Comet is only given access to their partners only and this need to pay 200$(Perplexity Pro) If you are an university student , you can get the early access from the below invitation link for 100% Free.

Report Abuse Thiyagarajan Thangavel Posted on Dec 2, 2025 Cleanup of Inactive AD Accounts (User & Computer) – Over 1 Year Old # azure # discuss # networksec Idea To improve Active Directory (AD) security hygiene, performance, and compliance with ARPAN or internal IT policies by identifying and removing inactive user and computer accounts that haven’t been used for over one year. Problem Statement Over time, user and computer accounts in Active Directory become stale due to employee attrition, decommissioned machines, or system account redundancies. These dormant accounts pose the following risks and issues: Security Risks: Inactive accounts are vulnerable to misuse or compromise. License Wastage: Consumes unnecessary licenses in environments like Microsoft 365. Administrative Overhead: Clutters AD with obsolete entries, complicating management. Compliance Gaps: May violate policies such as ARPAN which mandate timely account lifecycle management. Solution Implement a PowerShell-based automated process that: Identifies all user and computer accounts that have not logged on in over 365 days. Exports these accounts to CSV files for review and audit purposes. Deletes the reviewed accounts safely (with optional backup and logging steps). PowerShell Script (Summary): Benefits Enhanced Security: Minimizes attack surface by eliminating dormant accounts. Compliance Assurance: Meets ARPAN and internal audit standards for account lifecycle. Operational Efficiency: Reduces clutter in AD, improving admin productivity. Cost Optimization: Frees up licenses and reduces overhead in systems like Office 365 or Azure AD. # Load AD module Import-Module ActiveDirectory Set time threshold $timeThreshold = (Get-Date).AddDays(-365) --- Export Inactive User Accounts --- $inactiveUsers = Get-ADUser -Filter {LastLogonDate -lt $timeThreshold -and Enabled -eq $true} -Properties LastLogonDate | Select-Object Name, SamAccountName, LastLogonDate $inactiveUsers | Export-Csv -Path "C:\ADCleanup\InactiveUsers.csv" -NoTypeInformation Write-Host "Inactive users exported to InactiveUsers.csv" --- Export Inactive Computer Accounts --- $inactiveComputers = Get-ADComputer -Filter {LastLogonDate -lt $timeThreshold -and Enabled -eq $true} -Properties LastLogonDate | Select-Object Name, SamAccountName, LastLogonDate $inactiveComputers | Export-Csv -Path "C:\ADCleanup\InactiveComputers.csv" -NoTypeInformation Write-Host "Inactive computers exported to InactiveComputers.csv" Optional: Review before deleting Uncomment the following lines to perform deletion <# Delete Inactive Users $inactiveUsers | ForEach-Object { Remove-ADUser -Identity $_.SamAccountName -Confirm:$false } Delete Inactive Computers $inactiveComputers | ForEach-Object { Remove-ADComputer -Identity $_.SamAccountName -Confirm:$false } Write-Host "Inactive users and computers deleted." > Top comments (1) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Trishan Fernando Posted on Apr 2, 2025 Adding Field Attributes to multiple fields at once in Odoo # odoo # python When developing in Odoo, you might encounter situations where you need to add the same attribute to multiple fields. For instance, imagine you have a model with 20–30 fields and later decide to enable tracking on all of them. Adding the tracking attribute manually to each field definition would be time-consuming and potentially error-prone. This article explores how to leverage Odoo’s fields_get() method to identify fields and modify their attributes programmatically, saving significant development time. Understanding fields_get() Odoo provides a built-in method called fields_get() that returns all fields and their attributes for a specific model. This method has two optional arguments: field name and field attributes. Example Usage Here’s a simple example of how to use fields_get() to view all fields and their attributes in a model: When executed, this function will output something like: Practical Use Case: Adding Tracking to Multiple Fields Let’s look at a practical scenario where this approach is particularly useful. Imagine you’ve created a model with numerous fields, and after development, you decide that all fields should be tracked for audit purposes. Instead of modifying each field definition individually, you can use the following function: def add_attribute(self): model_obj = self.env['your.model.name'] fields = model_obj.fields_get() print(type(fields)) for field_name, field_attrs in fields.items(): # Get the field object from the model's _fields dictionary field_obj = model_obj._fields.get(field_name) if field_obj: # Check if tracking attribute is not already set or is False if not getattr(field_obj, 'tracking', False): # Skip fields that cannot be tracked if field_obj.type == 'one2many' or (field_obj.compute and not field_obj.store): print(f"Field {field_name} cannot be tracked (one2many or computed non-stored).") continue # Set tracking attribute to True field_obj.tracking = True print(f"Field {field_name} is now tracked.") else: print(f"Field {field_name} is already tracked.") else: print(f"Field {field_name} not found in model.") Enter fullscreen mode Exit fullscreen mode This function iterates through all fields in the specified model and sets the tracking attribute to True for eligible fields. It also includes validation to skip fields that cannot be tracked (like one2many fields or computed non-stored fields). Beyond Tracking: Additional Applications While our example focuses on adding tracking, this technique can be applied to modify any field attribute programmatically. Some other potential uses include: Adding specific groups to field access rights Modifying string attributes for internationalization Changing widget attributes for better UI display Setting default values across multiple fields Important Considerations When using this approach, keep these points in mind: Environment Impact: This modification happens at runtime and may not persist after server restart unless you’re modifying the actual field definitions in the Python code. Production Caution: Be careful when applying this in production environments, as modifying field attributes can have system-wide effects. Performance: For very large models, iterating through all fields could impact performance. Conclusion This approach provides an alternative method for modifying field attributes in Odoo models with multiple fields. While direct field definition remains the standard practice for most development scenarios, understanding how to programmatically modify attributes can be useful in specific situations where bulk changes are needed. The technique leverages Odoo’s built-in functionality to access field definitions, offering a way to make consistent changes across many fields without manual intervention. Stay Tuned !

Report Abuse Mohammad-Idrees Posted on Jan 13 Contrast sync vs async failure classes using first principles # architecture # computerscience # systemdesign 1. Start from First Principles: What Is a “Failure Class”? A failure class is not: a bug a timeout an outage A failure class is: A category of things that can go wrong because of how responsibility, time, and state are structured So we ask: What must be true for correctness? What assumptions does the model silently make? What breaks when those assumptions are false? 2. Core Difference (One Sentence) Synchronous systems fail by blocking and cascading. Asynchronous systems fail by duplication, reordering, and invisibility. Everything else is a consequence. 3. Synchronous Systems — Failure Classes Definition (First Principles) A synchronous system assumes: “The caller waits while the callee finishes the work.” This couples: time availability correctness Failure Class 1: Blocking Amplification Question asked: What happens while the system waits? Reality: Threads blocked Connections held Memory retained Failure mode: Load increases → latency increases → throughput collapses This is not just “slow.” It is non-linear failure . Failure Class 2: Cascading Failure Question asked: What if a dependency slows down? Because everything is waiting: Agent slows → backend slows Backend slows → frontend retries Retries amplify load Failure mode: One slow dependency can take down the entire system Failure Class 3: Availability Coupling Question asked: Can the system function if the dependency is down? Answer in sync systems: No Failure mode: Partial outage becomes total outage Summary: Sync Failure Classes Category Root Cause Blocking Time is coupled Cascades Dependencies are inline Global outage Availability is transitive 4. Asynchronous Systems — Failure Classes Definition (First Principles) An async system assumes: “Work can finish later, possibly multiple times, possibly out of order.” This decouples time but removes guarantees . Failure Class 1: Duplicate Execution Question asked: What happens if work is retried? Reality: At-least-once delivery Worker crashes Message reprocessed Failure mode: Same logical action happens multiple times This breaks: Exactly-once semantics Idempotency assumptions Failure Class 2: Ordering Violations Question asked: What defines sequence? Reality: Queues don’t know business order Workers process independently Failure mode: Effects appear out of logical order For chat systems: Responses based on future messages Context corruption Failure Class 3: Completion Invisibility Question asked: How does the user know when work is done? Reality: No direct signal Polling or guessing Failure mode: Users wait blindly or see stale state Failure Class 4: Orphaned Work Question asked: What if the user disappears? Reality: Job keeps running Response stored but never consumed Failure mode: Wasted compute, leaked state Summary: Async Failure Classes Category Root Cause Duplication Retries Reordering Decoupled execution Invisibility No direct completion path Orphans Detached lifecycles 5. Side-by-Side Contrast (Mental Model) Dimension Synchronous Asynchronous Time Coupled Decoupled Failure style Blocking, cascades Duplication, disorder Availability All-or-nothing Partial Correctness risk Latency-based Logic-based Debugging Easier Harder 6. Deep Insight (This Is the Interview Gold) Synchronous systems fail loudly and immediately. Asynchronous systems fail quietly and later. Sync failures are obvious (timeouts, errors) Async failures are subtle (double writes, wrong order) 7. Why Neither Is “Better” From first principles: Sync systems protect causality but sacrifice availability Async systems protect availability but sacrifice causality Real systems exist to reintroduce the lost property : Async systems add idempotency, ordering, state machines Sync systems add timeouts, circuit breakers, fallbacks 8. One-Line Rule to Remember Sync breaks under load. Async breaks under ambiguity. If you want next, we can: Map these failure classes to real outages Show how streaming combines both failure types Practice identifying failure classes on a fresh system Tell me the next direction.

Report Abuse Mohammad-Idrees Posted on Jan 13 Contrast sync vs async failure classes using first principles # architecture # computerscience # systemdesign 1. Start from First Principles: What Is a “Failure Class”? A failure class is not: a bug a timeout an outage A failure class is: A category of things that can go wrong because of how responsibility, time, and state are structured So we ask: What must be true for correctness? What assumptions does the model silently make? What breaks when those assumptions are false? 2. Core Difference (One Sentence) Synchronous systems fail by blocking and cascading. Asynchronous systems fail by duplication, reordering, and invisibility. Everything else is a consequence. 3. Synchronous Systems — Failure Classes Definition (First Principles) A synchronous system assumes: “The caller waits while the callee finishes the work.” This couples: time availability correctness Failure Class 1: Blocking Amplification Question asked: What happens while the system waits? Reality: Threads blocked Connections held Memory retained Failure mode: Load increases → latency increases → throughput collapses This is not just “slow.” It is non-linear failure . Failure Class 2: Cascading Failure Question asked: What if a dependency slows down? Because everything is waiting: Agent slows → backend slows Backend slows → frontend retries Retries amplify load Failure mode: One slow dependency can take down the entire system Failure Class 3: Availability Coupling Question asked: Can the system function if the dependency is down? Answer in sync systems: No Failure mode: Partial outage becomes total outage Summary: Sync Failure Classes Category Root Cause Blocking Time is coupled Cascades Dependencies are inline Global outage Availability is transitive 4. Asynchronous Systems — Failure Classes Definition (First Principles) An async system assumes: “Work can finish later, possibly multiple times, possibly out of order.” This decouples time but removes guarantees . Failure Class 1: Duplicate Execution Question asked: What happens if work is retried? Reality: At-least-once delivery Worker crashes Message reprocessed Failure mode: Same logical action happens multiple times This breaks: Exactly-once semantics Idempotency assumptions Failure Class 2: Ordering Violations Question asked: What defines sequence? Reality: Queues don’t know business order Workers process independently Failure mode: Effects appear out of logical order For chat systems: Responses based on future messages Context corruption Failure Class 3: Completion Invisibility Question asked: How does the user know when work is done? Reality: No direct signal Polling or guessing Failure mode: Users wait blindly or see stale state Failure Class 4: Orphaned Work Question asked: What if the user disappears? Reality: Job keeps running Response stored but never consumed Failure mode: Wasted compute, leaked state Summary: Async Failure Classes Category Root Cause Duplication Retries Reordering Decoupled execution Invisibility No direct completion path Orphans Detached lifecycles 5. Side-by-Side Contrast (Mental Model) Dimension Synchronous Asynchronous Time Coupled Decoupled Failure style Blocking, cascades Duplication, disorder Availability All-or-nothing Partial Correctness risk Latency-based Logic-based Debugging Easier Harder 6. Deep Insight (This Is the Interview Gold) Synchronous systems fail loudly and immediately. Asynchronous systems fail quietly and later. Sync failures are obvious (timeouts, errors) Async failures are subtle (double writes, wrong order) 7. Why Neither Is “Better” From first principles: Sync systems protect causality but sacrifice availability Async systems protect availability but sacrifice causality Real systems exist to reintroduce the lost property : Async systems add idempotency, ordering, state machines Sync systems add timeouts, circuit breakers, fallbacks 8. One-Line Rule to Remember Sync breaks under load. Async breaks under ambiguity. If you want next, we can: Map these failure classes to real outages Show how streaming combines both failure types Practice identifying failure classes on a fresh system Tell me the next direction.

Report Abuse Trishan Fernando Posted on Mar 31, 2025 OWL JS 01 — Why Odoo Created OWL: A Framework Built for Modularity # odoo # owl # odooddevelopment # webdev In the JavaScript ecosystem filled with established frameworks like React and Vue, Odoo's decision to create their own framework—OWL (Odoo Web Library)—might seem counterintuitive. After all, why reinvent the wheel? This article explores the key reasons behind this strategic choice and highlights what makes OWL uniquely suited for Odoo's specific needs. The Core Challenge: Extreme Modularity At the heart of Odoo's decision lies one fundamental characteristic: Odoo is extremely modular . This means: Core components don't know beforehand what files will be loaded or executed The UI state is determined entirely at runtime Standard build toolchains aren't viable Odoo isn't just an application with a UI; it's an application that generates a dynamic UI This modularity creates unique requirements that most established frameworks aren't designed to address. Key Considerations Behind Creating OWL 1. Technical Independence Odoo needed to maintain control over their technology stack without depending on decisions made by large companies like Facebook (React) or Google. If these companies changed their licensing or technical direction, it could create significant problems for Odoo's specialized needs. 2. Class Components While modern frameworks are moving away from class components toward functional approaches, Odoo specifically benefits from class-based architecture: Inheritance provides an effective way to share code between generic components Each class method serves as an extension point for addons Components can be monkey-patched to add behavior from outside 3. JIT Template Compilation Odoo's dynamic nature requires just-in-time compilation: Templates are stored as XML in a database and customized via XPaths Templates need to be fetched and compiled at the last possible moment The system must be able to generate and compile templates at runtime 4. Minimal Tooling Requirements OWL is designed to work with minimal mandatory tooling: Templates are compiled by the browser using built-in XML parsers Components can be written with template strings The framework can be integrated with a simple <script> tag No complex build pipeline is required on production servers 5. XML-Based Templates Odoo stores templates as XML documents, allowing for powerful customization through XPaths. This feature is central to Odoo's modularity but isn't well-supported by other frameworks. 6. Simplified Developer Experience OWL prioritizes straightforward APIs: Uses familiar class-based components Features an explicit reactivity system Implements clear scoping rules Avoids unnecessary complexity 7. Optional Reactivity and Concurrency OWL offers: A reactive system that can be optionally disabled when not needed A powerful yet simple concurrent mode for managing asynchronous state changes Conclusion Creating OWL wasn't a decision Odoo made lightly. While established frameworks excel in their designed contexts, Odoo's unique requirements demanded something different. OWL represents a framework built specifically for extreme modularity, just-in-time compilation, and developer accessibility—making it the right tool for Odoo's specialized ecosystem.

Report Abuse Gaurav Singh Posted on Dec 26, 2025 Scaling the Data Layer in Distributed Systems # systemdesign # database # backend # java Scaling a stateless system is relatively straightforward. We can horizontally scale application servers by adding more instances behind a load balancer, and the system continues to work as expected. But what happens to the database? How can a database running on a single machine handle requests coming from N horizontally scaled application servers? Databases must scale too — and this is where things get interesting. The First Idea: Replication A natural first thought is: “Let’s just replicate the database and create multiple copies.” At first glance, this sounds reasonable. But the moment we try to scale traditional SQL databases using replication, we run into fundamental constraints. Why SQL Databases Don’t Scale Easily SQL databases are built around powerful guarantees: Joins across tables Cross-row and multi-table transactions Global constraints (foreign keys, unique keys, auto-increment IDs) All of these assume one critical thing: All data lives in one logical place. Once we attempt to shard or distribute SQL data: Joins turn into cross-network calls Transactions span machines Locks stop working globally As a result: Complexity explodes Performance degrades Application logic becomes significantly more complex This doesn’t mean SQL cannot be sharded — it can — but doing so safely requires heavy coordination and careful design. The Leader–Follower Model To improve scalability, many systems move to a leader–follower replication model. Press enter or click to view image in full size How It Works A single leader (primary) accepts all writes Followers (replicas) copy data from the leader Reads may be served from followers to scale read traffic This gives us: One source of truth for writes Multiple copies for read scaling and fault tolerance But a key question remains: How does the leader propagate writes to followers? The answer lies in replication strategies. Replication Strategies in Leader–Follower Systems Strong Consistency (Synchronous Replication) In this model: The leader writes data locally The leader waits for acknowledgements from a quorum (majority) of replicas Only then does it respond to the client This ensures: Strong consistency No stale reads (when reads also use quorum or leader) Tradeoffs: Higher write latency Reduced availability if replicas are slow or unavailable Importantly, strong consistency does not require waiting for all followers — waiting for a majority is sufficient. Eventual Consistency (Asynchronous Replication) Here: The leader writes data locally It sends replication messages to followers It responds to the client without waiting for most acknowledgements This model: Improves write latency and throughput Allows reads from followers to return stale data temporarily Relies on the system eventually converging This is a deliberate tradeoff: Availability and performance over immediate consistency The Leader Bottleneck Problem Even with replication, a fundamental limitation remains: All writes still go through a single leader. As write QPS grows (e.g., 10K+ writes per second): The leader becomes a bottleneck CPU, I/O, and replication overhead increase Vertical scaling eventually hits limits At this point, simply adding more replicas doesn’t help — because replicas don’t accept writes. This is where partitioning (sharding) becomes necessary. The Entry of NoSQL NoSQL databases emerged to solve exactly this problem: scaling writes and reads horizontally at massive scale. Key motivations behind NoSQL systems: High write throughput High availability Fault tolerance Geo-distribution Low latency at scale Rather than optimizing purely for normalization and storage efficiency, NoSQL systems are designed to scale by default. Sharding in NoSQL Databases NoSQL databases distribute data using sharding. How Sharding Works A partition (shard) key is chosen (e.g., user_id) The key is hashed or range-mapped Data is distributed across shards Each shard owns a mutually exclusive subset of data Common partitioning strategies: Consistent hashing Range-based partitioning (A–G, H–M, etc.) Choosing the correct shard key is critical: A poor shard key can cause hotspots and destroy scalability. Replication Inside a Shard Each shard is still replicated for fault tolerance. This is where two NoSQL replication models appear. Model 1: Leader–Follower per Shard Used by systems like: MongoDB DynamoDB HBase Per Shard: One leader Multiple followers Write Flow: Client routes request to shard leader Leader writes data Leader propagates to followers Leader waits for: Quorum acknowledgements (stronger consistency), or Minimal acknowledgements (eventual consistency) Read Flow: Reads may go to leader (fresh) Or followers (faster, possibly stale) This model is simple and efficient but still has: Leader hotspots Leader failover complexity Model 2: Quorum-Based (Leaderless) Replication Used by systems like: Cassandra Riak Dynamo-style designs Per Shard: No leader All replicas are equal Write Flow: Client sends write to any replica (coordinator) Coordinator sends write to all replicas Write succeeds when W replicas acknowledge Read Flow: Client reads from R replicas Latest version wins Inconsistencies are repaired in the background This model: Avoids leader bottlenecks Improves availability Requires conflict resolution and versioning Quorum Explained (Simply) Let: N = total replicas per shard W = replicas required to acknowledge a write R = replicas required for a read Rules: Strong consistency: R + W > N Eventual consistency: R + W ≤ N Examples: Banking, inventory → strong consistency Social feeds, likes, analytics → eventual consistency Quorum decisions are made per shard, not globally. Final Takeaway SQL databases struggle with horizontal write scaling due to strong global guarantees Leader–follower replication improves read scaling but not write scaling NoSQL databases solve this by sharding data ownership Each shard scales independently Replication within shards is handled using leader-based or quorum-based models Consistency is a configurable tradeoff, not a fixed property Modern data systems don’t ask “Can we scale?” — they ask “What consistency are we willing to trade for scale?” Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse eachampagne Posted on Nov 17, 2025 • Edited on Dec 6, 2025 Garbage Collection # computerscience # performance # programming It’s easy to forget, while working in the abstract in terms of functions and algorithms, that the memory our programs depend on is real . The values we use in our programs actually exist on the hardware at specific addresses. If we don’t keep track of where we’ve stored data, we run the risk of overwriting something important and getting the wrong information when we go to look it up again. On the other hand, if we’re too guarded about protecting our data, even after we’re finished with it, we waste memory that the program could better use on other tasks. Most programming languages today implement garbage collection to automate periodically releasing memory we no longer need. The garbage collector cannot predict exactly which values will be used again by our program, but it can find some that cannot due to no longer having any way to use them, and safely free them. Garbage Collection Algorithms Reference Counting The simplest algorithm is just to keep a count of references to a piece of memory. If the number of references ever reaches zero, that memory can no longer be reached and can be safely disposed of. However, this strategy fails with circular references. If two objects, for example, reference each other, their reference counts with never reach zero, even if they are otherwise inaccessible from the main program. Tracing Tracing (usually mark-and-sweep), is a more sophisticated approach to memory management. Starting from some defined root(s), the garbage collector visits every piece of memory accessible from either the root or its descendants, marking that memory as still reachable. Any memory not traversed is unreachable and is garbage collected. This avoids the problem of circular references “trapping” memory, since the cycle will not be reached from the main memory graph. However, this approach has more overhead than the reference counting strategy. Many garbage collectors reduce the overhead of mark-and-search by having two (or more) “generations” of allocations. The generational hypothesis states that most allocations die young (think how many variables you use once in a for loop and never again), but those that survive are much more likely to survive a long time. Thus, the pool of young allocations (the “nursery”) is garbage collected frequently, while the old (“tenured”) pool is checked less often. It’s possible to combine both strategies in a hybrid collector. For example, Python uses reference counting as its primary algorithm, then uses a mark-and-sweep pass over the (now smaller) pool of allocated memory to find and eliminate circular references. The Downsides of Garbage Collection Of course, the garbage collector itself introduces some overhead. Depending on the implementation, it may bring the program to a halt while it scans and frees data or defragments the remaining memory. It is also impossible to create a perfectly efficient garbage collector due to the inherent uncertainty in which values will be used again. Other Approaches to Memory Management There are alternatives to garbage collection. A few languages, such as C and C++, require the programmer to manage memory manually (although you can add garbage collectors to both languages yourself if you wish), both while allocating memory to new variables and when deciding when to free memory. Manual memory management avoids the overhead of garbage collection, but adds to program complexity, since this now must be handled by the code itself rather than happening in the background. This also gives the programmer many opportunities to make mistakes , from creating floating pointers by freeing too soon to leaking memory by freeing too late or not at all, to say nothing of the difficulty of using pointers themselves. Rust takes a third option and introduces the concept of “ ownership ” – only one variable can own a piece of data at a time, and that data is released as soon as its owner goes out of scope. This eliminates the need for garbage collection at runtime, as well with its associated performance costs. However, the programmer has to keep track of ownership and borrowing of data, which limits how data can be read or changed at certain points of the program. This requires thinking in a different way from other languages, since some familiar patterns simply won’t compile, and increases Rust’s learning curve sharply. Garbage Collection in JavaScript JavaScript follows the majority of programming languages in using a garbage collector. However, the garbage collector itself is implemented and run by the JavaScript engine, not the script we write ourselves, so implementation varies slightly across engines. However, the general principles are the same. Modern JavaScript libraries all use a mark-and-sweep algorithm with the global object as the algorithm’s root. Since I regularly use Firefox and Node, I’ll look at their engines in a bit more detail. SpiderMonkey , the engine used by Firefox, applies the principle of generational collection, dividing allocations into young and old. It attempts to garbage collect incrementally to avoid long pauses, and runs parts of garbage collection in parallel with itself or concurrently with the main thread when possible. The V8 engine’s Orinoco garbage collector , has three generations: nursery, young, and old, and claims (as of 2019) to be a “mostly parallel and concurrent collector with incremental fallback.” V8 also brags about interweaving garbage collection into the idle time between drawing frames when possible, minimizing the time spent forcing JavaScript execution to pause. Based only on these descriptions, V8’s garbage collector seems a bit more advanced, perhaps because V8 used by Chromium-based browsers in addition to Node.js and thus has more support. However, they seem to have independently converged to similar architectures. The serious demands to provide a smooth user experience means that browser-based garbage collectors must be efficient and eliminate as much overhead as possible, because, as the Node guide to tracing garbage collection neatly summarizes, “ when GC is running, your code is not. ” I admit I’ve rather taken memory management for granted, since most of the languages I’ve studied have garbage collectors. I’ve been fascinated by Rust for years but haven’t managed to wrap my head around its ownership and borrowing rules. (Maybe this is the time it will finally click for me.) But if I struggle with memory management when the compiler itself is looking out for me, I’m not sure how I’d fare in a manual memory management scheme without guardrails. So for now, I’m very grateful to garbage collectors everywhere for making my life easier. The Memory Management Reference was invaluable while researching this blog post, in addition to many other engine- and language-specific references (linked throughout the text).

Report Abuse nicomedina Posted on Jan 13 How I built a high-performance Social API with Bun & ElysiaJS on a $5 VPS (handling 3.6k reqs/min) # bunjs # api # javascript # programming The Goal I wanted to build a "Micro-Social" API—a backend service capable of handling Twitter-like feeds, follows, and likes—without breaking the bank. My constraints were simple: Budget:** $5 - $20 / month. Performance:** Sub-300ms latency. Scale:** Must handle concurrent load (stress testing). Most tutorials show you Hello World . This post shows you what happens when you actually hit Hello World with 25 concurrent users on a cheap VPS. (Spoiler: It crashes). Here is how I fixed it. ## The Stack 🛠️ I chose Bun over Node.js for its startup speed and built-in tooling. Runtime: Bun Framework: ElysiaJS (Fastest Bun framework) Database: PostgreSQL (via Dokploy) ORM: Drizzle (Lightweight & Type-safe) Hosting: VPS with Dokploy (Docker Compose) The "Oh Sh*t" Moment 🚨 I deployed my first version. It worked fine for me. Then I ran a load test using k6 to simulate 25 virtual users browsing various feeds. k6 run tests/stress-test.js Enter fullscreen mode Exit fullscreen mode Result: ✗ http_req_failed................: 86.44% ✗ status is 429..................: 86.44% The server wasn't crashing, but it was rejecting almost everyone. Diagnosis I initially blamed Traefik (the reverse proxy). But digging into the code, I found the culprit was me . // src/index.ts // OLD CONFIGURATION . use ( rateLimit ({ duration : 60 _000 , max : 100 // 💀 100 requests per minute... GLOBAL per IP? })) Enter fullscreen mode Exit fullscreen mode Since my stress test (and likely any future NATed corporate office) sent all requests from a single IP, I was essentially DDOSing myself. The Fixes 🔧 1. Tuning the Rate Limiter I bumped the limit to 2,500 req/min . This prevents abuse while allowing heavy legitimate traffic (or load balancers). // src/index.ts . use ( rateLimit ({ duration : 60 _000 , max : 2500 // Much better for standard reliable APIs })) Enter fullscreen mode Exit fullscreen mode 2. Database Connection Pooling The default Postgres pool size is often small (e.g., 10 or 20). My VPS has 4GB RAM. PostgreSQL needs RAM for connections, but not that much. I bumped the pool to 80 connections . // src/db/index.ts const client = postgres ( process . env . DATABASE_URL , { max : 80 }); Enter fullscreen mode Exit fullscreen mode 3. Horizontal Scaling with Docker Node/Bun is single-threaded. A single container uses 1 CPU core effectivey. My VPS has 2 vCPUs. I added a replicas instruction to my docker-compose.dokploy.yml : api : build : . restart : always deploy : replicas : 2 # One for each core! Enter fullscreen mode Exit fullscreen mode This instantly doubled my throughput capacity. Traefik automatically load-balances between the two containers. The Final Result 🟢 Ran k6 again: ✓ checks_succeeded...: 100.00% ✓ http_req_duration..: p(95)=200.45ms ✓ http_req_failed....: 0.00% (excluding auth checks) Enter fullscreen mode Exit fullscreen mode 0 errors. 200ms latency. On a cheap VPS. Takeaway You don't need Kubernetes for a side project. You just need to understand where your bottlenecks are: Application Layer: Check your Rate Limits. Database Layer: Check your Connection Pool. Hardware: Use all your cores (Replicas). If you want to try the API, I published it on RapidAPI as Micro-Social API . https://rapidapi.com/ismamed4/api/micro-social Happy coding! 🚀 Top comments (1) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Boga Posted on Jan 12 Odoo Core and the Cost of Reinventing Everything # python # odoo # qweb # owl Hello, this is my first blog post ever. I’d like to share my experience working with Odoo , an open-source Enterprise Resource Planning (ERP) system, and explain why I believe many of its architectural choices cause unnecessary complexity. Odoo is a single platform that provides many prebuilt modules (mini-applications) that most companies need. For example, almost every company requires a Human Resources system to manage employee details, leaves, attendance, contracts, resignations, and more. Beyond HR, companies also need purchasing, inventory, accounting, authentication, authorization, and other systems. Odoo bundles all of these tightly coupled systems into a single installation. On paper, this sounds great — and from a business perspective, it often is. From a technical perspective , however, things get complicated very quickly. Odoo Core Components Below are the main Odoo components, ranked from least complex to most complex, and all largely developed in-house instead of relying on existing mature frameworks: Odoo HTTP Layer JSON-RPC Website routing Odoo Views XML transformed into Python and JavaScript Odoo ORM Custom inheritance system Query builder Dependency injection Caching layers Cache System Implemented from scratch WebSocket Implementation Very low-level handling Odoo HTTP Layer Odoo is not built on a standard Python web framework like Django or Flask. Instead, it implements its own HTTP framework on top of Werkzeug (a WSGI utility library). This HTTP layer introduces its own abstractions, request lifecycle, routing, and serialization logic, including JSON-RPC and website controllers. While technically impressive, it reinvents many problems that have already been solved — and battle-tested — by existing frameworks. Odoo Views In my opinion, this is one of the most problematic parts of Odoo. Instead of using standard frontend technologies, Odoo relies heavily on XML-based views . These XML files are sent to the browser and then transformed using Abstract Syntax Tree (AST) analysis into JavaScript. In other contexts (like the website), the XML may be converted into Python code and sometimes back into JavaScript again. This creates: High cognitive overhead Difficult debugging Tight coupling between backend and frontend Poor tooling support compared to modern frontend stacks It feels like building a car from raw metal just to drive from point A to point B. Odoo ORM Odoo’s ORM is not a typical ORM. It implements: A custom inheritance system (instead of using Python’s built-in one) Its own dependency injection mechanism A query builder Caching layers (LRU) Model extension via monkey-patching While powerful, this system is extremely complex and hard to reason about. Debugging model behavior often feels like navigating invisible layers of magic. WebSocket Implementation Instead of using a mature real-time framework, Odoo implements its WebSocket handling with very low-level logic, sometimes in surprisingly small and dense files. A single comment from the codebase summarizes this approach better than words ever could: The “Odoo Is Old” Argument A common defense of Odoo’s architecture is that “it’s an old system” — originally developed around 2005 using Python 2. However, this argument no longer holds. Odoo was largely rewritten from scratch around 2017 to support Python 3. At that time, many excellent frameworks already existed and had solved the same problems more cleanly, while continuing to evolve without breaking their ecosystems. Today, even small changes in Odoo’s core can break custom modules unless they are limited to simple CRUD models with minimal dependencies on core behavior. Final Thoughts Odoo is a powerful product and a successful business platform. But from a software engineering perspective, many of its design decisions prioritize control and internal consistency over maintainability, clarity, and developer experience . If you work with Odoo long enough, you stop asking “why does it work this way?” and start asking “how do I survive this upgrade?” Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Mohammad-Idrees Posted on Jan 13 Contrast sync vs async failure classes using first principles # architecture # computerscience # systemdesign 1. Start from First Principles: What Is a “Failure Class”? A failure class is not: a bug a timeout an outage A failure class is: A category of things that can go wrong because of how responsibility, time, and state are structured So we ask: What must be true for correctness? What assumptions does the model silently make? What breaks when those assumptions are false? 2. Core Difference (One Sentence) Synchronous systems fail by blocking and cascading. Asynchronous systems fail by duplication, reordering, and invisibility. Everything else is a consequence. 3. Synchronous Systems — Failure Classes Definition (First Principles) A synchronous system assumes: “The caller waits while the callee finishes the work.” This couples: time availability correctness Failure Class 1: Blocking Amplification Question asked: What happens while the system waits? Reality: Threads blocked Connections held Memory retained Failure mode: Load increases → latency increases → throughput collapses This is not just “slow.” It is non-linear failure . Failure Class 2: Cascading Failure Question asked: What if a dependency slows down? Because everything is waiting: Agent slows → backend slows Backend slows → frontend retries Retries amplify load Failure mode: One slow dependency can take down the entire system Failure Class 3: Availability Coupling Question asked: Can the system function if the dependency is down? Answer in sync systems: No Failure mode: Partial outage becomes total outage Summary: Sync Failure Classes Category Root Cause Blocking Time is coupled Cascades Dependencies are inline Global outage Availability is transitive 4. Asynchronous Systems — Failure Classes Definition (First Principles) An async system assumes: “Work can finish later, possibly multiple times, possibly out of order.” This decouples time but removes guarantees . Failure Class 1: Duplicate Execution Question asked: What happens if work is retried? Reality: At-least-once delivery Worker crashes Message reprocessed Failure mode: Same logical action happens multiple times This breaks: Exactly-once semantics Idempotency assumptions Failure Class 2: Ordering Violations Question asked: What defines sequence? Reality: Queues don’t know business order Workers process independently Failure mode: Effects appear out of logical order For chat systems: Responses based on future messages Context corruption Failure Class 3: Completion Invisibility Question asked: How does the user know when work is done? Reality: No direct signal Polling or guessing Failure mode: Users wait blindly or see stale state Failure Class 4: Orphaned Work Question asked: What if the user disappears? Reality: Job keeps running Response stored but never consumed Failure mode: Wasted compute, leaked state Summary: Async Failure Classes Category Root Cause Duplication Retries Reordering Decoupled execution Invisibility No direct completion path Orphans Detached lifecycles 5. Side-by-Side Contrast (Mental Model) Dimension Synchronous Asynchronous Time Coupled Decoupled Failure style Blocking, cascades Duplication, disorder Availability All-or-nothing Partial Correctness risk Latency-based Logic-based Debugging Easier Harder 6. Deep Insight (This Is the Interview Gold) Synchronous systems fail loudly and immediately. Asynchronous systems fail quietly and later. Sync failures are obvious (timeouts, errors) Async failures are subtle (double writes, wrong order) 7. Why Neither Is “Better” From first principles: Sync systems protect causality but sacrifice availability Async systems protect availability but sacrifice causality Real systems exist to reintroduce the lost property : Async systems add idempotency, ordering, state machines Sync systems add timeouts, circuit breakers, fallbacks 8. One-Line Rule to Remember Sync breaks under load. Async breaks under ambiguity. If you want next, we can: Map these failure classes to real outages Show how streaming combines both failure types Practice identifying failure classes on a fresh system Tell me the next direction.

Report Abuse Boga Posted on Jan 12 Odoo Core and the Cost of Reinventing Everything # python # odoo # qweb # owl Hello, this is my first blog post ever. I’d like to share my experience working with Odoo , an open-source Enterprise Resource Planning (ERP) system, and explain why I believe many of its architectural choices cause unnecessary complexity. Odoo is a single platform that provides many prebuilt modules (mini-applications) that most companies need. For example, almost every company requires a Human Resources system to manage employee details, leaves, attendance, contracts, resignations, and more. Beyond HR, companies also need purchasing, inventory, accounting, authentication, authorization, and other systems. Odoo bundles all of these tightly coupled systems into a single installation. On paper, this sounds great — and from a business perspective, it often is. From a technical perspective , however, things get complicated very quickly. Odoo Core Components Below are the main Odoo components, ranked from least complex to most complex, and all largely developed in-house instead of relying on existing mature frameworks: Odoo HTTP Layer JSON-RPC Website routing Odoo Views XML transformed into Python and JavaScript Odoo ORM Custom inheritance system Query builder Dependency injection Caching layers Cache System Implemented from scratch WebSocket Implementation Very low-level handling Odoo HTTP Layer Odoo is not built on a standard Python web framework like Django or Flask. Instead, it implements its own HTTP framework on top of Werkzeug (a WSGI utility library). This HTTP layer introduces its own abstractions, request lifecycle, routing, and serialization logic, including JSON-RPC and website controllers. While technically impressive, it reinvents many problems that have already been solved — and battle-tested — by existing frameworks. Odoo Views In my opinion, this is one of the most problematic parts of Odoo. Instead of using standard frontend technologies, Odoo relies heavily on XML-based views . These XML files are sent to the browser and then transformed using Abstract Syntax Tree (AST) analysis into JavaScript. In other contexts (like the website), the XML may be converted into Python code and sometimes back into JavaScript again. This creates: High cognitive overhead Difficult debugging Tight coupling between backend and frontend Poor tooling support compared to modern frontend stacks It feels like building a car from raw metal just to drive from point A to point B. Odoo ORM Odoo’s ORM is not a typical ORM. It implements: A custom inheritance system (instead of using Python’s built-in one) Its own dependency injection mechanism A query builder Caching layers (LRU) Model extension via monkey-patching While powerful, this system is extremely complex and hard to reason about. Debugging model behavior often feels like navigating invisible layers of magic. WebSocket Implementation Instead of using a mature real-time framework, Odoo implements its WebSocket handling with very low-level logic, sometimes in surprisingly small and dense files. A single comment from the codebase summarizes this approach better than words ever could: The “Odoo Is Old” Argument A common defense of Odoo’s architecture is that “it’s an old system” — originally developed around 2005 using Python 2. However, this argument no longer holds. Odoo was largely rewritten from scratch around 2017 to support Python 3. At that time, many excellent frameworks already existed and had solved the same problems more cleanly, while continuing to evolve without breaking their ecosystems. Today, even small changes in Odoo’s core can break custom modules unless they are limited to simple CRUD models with minimal dependencies on core behavior. Final Thoughts Odoo is a powerful product and a successful business platform. But from a software engineering perspective, many of its design decisions prioritize control and internal consistency over maintainability, clarity, and developer experience . If you work with Odoo long enough, you stop asking “why does it work this way?” and start asking “how do I survive this upgrade?” Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Beck_Moulton Posted on Jan 13 Stop Sending Sensitive Data to the Cloud: Build a Local-First Mental Health AI with WebLLM # privacy # typescript # webgpu # webllm In an era where data breaches are common, privacy in Edge AI has moved from a "nice-to-have" to a "must-have," especially in sensitive fields like healthcare. If you've ever worried about your private conversations being used to train a massive corporate model, you're not alone. Today, we are exploring the frontier of Privacy-preserving AI by building a medical Q&A bot that runs entirely on the client side. By leveraging WebLLM , WebGPU , and TVM Unity , we can now execute large language models directly in the browser. This means the dialogue never leaves the user's device, providing a truly decentralized and secure experience. For those looking to scale these types of high-performance implementations, I highly recommend checking out the WellAlly Tech Blog for more production-ready patterns on enterprise-grade AI deployment. The Architecture: Why WebGPU? Traditional AI apps send a request to a server (Python/FastAPI), which queries a GPU (NVIDIA A100), and sends a JSON response back. This "Client-Server" model is the privacy killer. Our "Local-First" approach uses WebGPU , the next-gen graphics API for the web, to tap into the user's hardware directly. graph TD subgraph User_Device [User Browser / Device] A[React UI Layer] -->|Dispatch| B[WebLLM Worker] B -->|Request Execution| C[TVM Unity Runtime] C -->|Compute Kernels| D[WebGPU API] D -->|Inference| E[VRAM / GPU Hardware] E -->|Streaming Text| B B -->|State Update| A end F((Public Internet)) -.->|Static Assets & Model Weights| A F -.->|NO PRIVATE DATA SENT| A Enter fullscreen mode Exit fullscreen mode Prerequisites Before we dive in, ensure you have a browser that supports WebGPU (Chrome 113+ or Edge). Framework : React (Vite template) Language : TypeScript AI Engine : @mlc-ai/web-llm Core Tech : WebGPU & TVM Unity Step 1: Initializing the Engine Running an LLM in a browser requires significant memory management. We use a Web Worker to ensure the UI doesn't freeze while the model is "thinking." // engine.ts import { CreateMLCEngine , MLCEngineConfig } from " @mlc-ai/web-llm " ; const modelId = " Llama-3-8B-Instruct-v0.1-q4f16_1-MLC " ; // Lightweight quantized model export async function initializeEngine ( onProgress : ( p : number ) => void ) { const engine = await CreateMLCEngine ( modelId , { initProgressCallback : ( report ) => { onProgress ( Math . round ( report . progress * 100 )); console . log ( report . text ); }, }); return engine ; } Enter fullscreen mode Exit fullscreen mode Step 2: Creating the Privacy-First Chat Hook In a medical context, the system prompt is critical. We need to instruct the model to behave as a supportive assistant while maintaining strict safety boundaries. // useChat.ts import { useState } from ' react ' ; import { initializeEngine } from ' ./engine ' ; export const useChat = () => { const [ engine , setEngine ] = useState < any > ( null ); const [ messages , setMessages ] = useState < { role : string , content : string }[] > ([]); const startConsultation = async () => { const instance = await initializeEngine (( p ) => console . log ( `Loading: ${ p } %` )); setEngine ( instance ); // Set the System Identity for Mental Health await instance . chat . completions . create ({ messages : [{ role : " system " , content : " You are a private, empathetic mental health assistant. Your goal is to listen and provide support. You do not store data. If a user is in danger, provide emergency resources immediately. " }], }); }; const sendMessage = async ( input : string ) => { const newMessages = [... messages , { role : " user " , content : input }]; setMessages ( newMessages ); const reply = await engine . chat . completions . create ({ messages : newMessages , }); setMessages ([... newMessages , reply . choices [ 0 ]. message ]); }; return { messages , sendMessage , startConsultation }; }; Enter fullscreen mode Exit fullscreen mode Step 3: Optimizing for Performance (TVM Unity) The magic behind WebLLM is TVM Unity , which compiles models into highly optimized WebGPU kernels. This allows us to run models like Llama-3 or Mistral at impressive tokens-per-second on a standard Macbook or high-end Windows laptop. If you are dealing with advanced production scenarios—such as model sharding or custom quantization for specific medical datasets—the team at WellAlly Tech has documented extensive guides on optimizing WebAssembly runtimes for maximum throughput. Step 4: Building the React UI A simple, clean interface is best for mental health applications. We want the user to feel calm and secure. // ChatComponent.tsx import React , { useState } from ' react ' ; import { useChat } from ' ./useChat ' ; export const MentalHealthBot = () => { const { messages , sendMessage , startConsultation } = useChat (); const [ input , setInput ] = useState ( "" ); return ( < div className = "p-6 max-w-2xl mx-auto border rounded-xl shadow-lg bg-white" > < h2 className = "text-2xl font-bold mb-4" > Shielded Mind AI 🛡️ </ h2 > < p className = "text-sm text-gray-500 mb-4" > Status: < span className = "text-green-500" > Local Only (Encrypted by Hardware) </ span ></ p > < div className = "h-96 overflow-y-auto mb-4 p-4 bg-gray-50 rounded" > { messages . map (( m , i ) => ( < div key = { i } className = { `mb-2 ${ m . role === ' user ' ? ' text-blue-600 ' : ' text-gray-800 ' } ` } > < strong > { m . role === ' user ' ? ' You: ' : ' AI: ' } </ strong > { m . content } </ div > )) } </ div > < div className = "flex gap-2" > < input className = "flex-1 border p-2 rounded" value = { input } onChange = { ( e ) => setInput ( e . target . value ) } placeholder = "How are you feeling today?" /> < button onClick = { () => { sendMessage ( input ); setInput ( "" ); } } className = "bg-purple-600 text-white px-4 py-2 rounded hover:bg-purple-700" > Send </ button > </ div > < button onClick = { startConsultation } className = "mt-4 text-xs text-gray-400 underline" > Initialize Secure WebGPU Engine </ button > </ div > ); }; Enter fullscreen mode Exit fullscreen mode Challenges & Solutions Model Size : Downloading a 4GB-8GB model to a browser is the biggest hurdle. Solution : Use IndexedDB caching so the user only downloads the model once. VRAM Limits : Mobile devices may struggle with large context windows. Solution : Implement sliding window attention and aggressive 4-bit quantization. Cold Start : The initial "Loading" phase can take time. Solution : Use a skeleton screen and explain that this process ensures their privacy. Conclusion By moving the "brain" of our AI from the cloud to the user's browser, we've created a psychological safe space that is literally impossible for hackers to intercept at the server level. WebLLM and WebGPU are turning browsers into powerful AI engines. Want to dive deeper into Edge AI security , LLM Quantization , or WebGPU performance tuning ?

Report Abuse Venkata Pavan Vishnu Rachapudi for AWS Community Builders Posted on Jan 12 🩺 How I Troubleshoot an EC2 Instance in the Real World (Using Instance Diagnostics) # aws # ec2 # linux # cloud When an EC2 instance starts misbehaving, my first reaction is not to SSH into it or reboot it. Instead, I open the EC2 console and go straight to Instance Diagnostics . Over time, I’ve realized that most EC2 issues can be understood — and often solved — just by carefully reading what AWS already shows on this page. In this blog, I’ll explain how I use each section of Instance Diagnostics to troubleshoot EC2 issues in a practical, real-world way. The First Question I Answer Before touching anything, I ask myself one simple question: Is this an AWS infrastructure issue, or is it something inside my instance? Instance Diagnostics helps answer this in seconds. Status Overview: Always the Starting Point I always begin with the Status Overview at the top. Instance State This confirms whether the instance is running, stopped, or terminated. If it is not running, there is usually nothing to troubleshoot. System Status Check This reflects the health of the underlying AWS infrastructure such as the physical host and networking. If this check fails, the issue is on the AWS side. In most cases, stopping and starting the instance resolves it by moving the instance to a healthy host. Instance Status Check This check represents the health of the operating system and internal networking. If this fails, the problem is inside the instance — typically related to OS boot issues, kernel problems, firewall rules, or resource exhaustion. EBS Status Check This confirms the health of the attached EBS volumes. If this fails, disk or storage-level issues are likely, and data protection becomes the immediate priority. CloudTrail Events: Tracking Configuration Changes If an issue appears suddenly, the CloudTrail Events tab is where I go next. I use it to confirm: Whether the instance was stopped, started, or rebooted If security groups or network settings were modified Whether IAM roles or instance profiles were changed If volumes were attached or detached This helps quickly identify human or automation-driven changes. SSM Command History: Understanding What Ran on the Instance The SSM Command History tab shows all Systems Manager Run Commands executed on the instance. This is especially useful for identifying: Patch jobs Maintenance scripts Automated remediations Configuration changes If there are no recent commands, that information itself is useful because it confirms that no SSM-driven actions caused the issue. Reachability Analyzer: When the Issue Is Network-Related If the instance is running but not reachable, I open the Reachability Analyzer directly from Instance Diagnostics. This is my go-to tool for diagnosing: Security group issues Network ACL misconfigurations Route table problems Internet gateway or NAT gateway connectivity VPC-to-VPC or on-prem connectivity issues Instead of guessing, Reachability Analyzer visually shows exactly where the network path is blocked. Instance Events: Checking AWS-Initiated Actions The Instance Events tab tells me if AWS has scheduled or performed any actions on the instance. This includes: Scheduled maintenance Host retirement Instance reboot notifications If an issue aligns with one of these events, the root cause becomes immediately clear. Instance Screenshot: When the OS Is Stuck If I cannot connect to the instance at all, I check the Instance Screenshot . This is especially helpful for: Identifying boot failures Detecting kernel panic messages Seeing whether the OS is stuck during startup Even a single screenshot can explain hours of troubleshooting. System Log: Understanding Boot and Kernel Issues The System Log provides low-level OS and kernel messages. I rely on it when: The instance fails to boot properly Services fail during startup Kernel or file system errors are suspected This is one of the best tools for diagnosing OS-level failures without logging in.

This allows me to: Inspect CPU, memory, and disk usage Restart services safely Avoid opening SSH ports or managing key pairs From both a security and operational standpoint, this is my preferred access method. What Experience Has Taught Me Troubleshooting EC2 instances is not about reacting quickly — it is about observing carefully. Instance Diagnostics already provides: Health signals Change history Network analysis OS-level visibility When used correctly, these tools eliminate guesswork and reduce downtime. Final Thoughts My approach to EC2 troubleshooting is simple: Start with Instance Diagnostics. Understand the signals. Act only after the root cause is clear. In most cases, the answer is already visible — we just need to slow down and read it.

Report Abuse Boga Posted on Jan 12 Odoo Core and the Cost of Reinventing Everything # python # odoo # qweb # owl Hello, this is my first blog post ever. I’d like to share my experience working with Odoo , an open-source Enterprise Resource Planning (ERP) system, and explain why I believe many of its architectural choices cause unnecessary complexity. Odoo is a single platform that provides many prebuilt modules (mini-applications) that most companies need. For example, almost every company requires a Human Resources system to manage employee details, leaves, attendance, contracts, resignations, and more. Beyond HR, companies also need purchasing, inventory, accounting, authentication, authorization, and other systems. Odoo bundles all of these tightly coupled systems into a single installation. On paper, this sounds great — and from a business perspective, it often is. From a technical perspective , however, things get complicated very quickly. Odoo Core Components Below are the main Odoo components, ranked from least complex to most complex, and all largely developed in-house instead of relying on existing mature frameworks: Odoo HTTP Layer JSON-RPC Website routing Odoo Views XML transformed into Python and JavaScript Odoo ORM Custom inheritance system Query builder Dependency injection Caching layers Cache System Implemented from scratch WebSocket Implementation Very low-level handling Odoo HTTP Layer Odoo is not built on a standard Python web framework like Django or Flask. Instead, it implements its own HTTP framework on top of Werkzeug (a WSGI utility library). This HTTP layer introduces its own abstractions, request lifecycle, routing, and serialization logic, including JSON-RPC and website controllers. While technically impressive, it reinvents many problems that have already been solved — and battle-tested — by existing frameworks. Odoo Views In my opinion, this is one of the most problematic parts of Odoo. Instead of using standard frontend technologies, Odoo relies heavily on XML-based views . These XML files are sent to the browser and then transformed using Abstract Syntax Tree (AST) analysis into JavaScript. In other contexts (like the website), the XML may be converted into Python code and sometimes back into JavaScript again. This creates: High cognitive overhead Difficult debugging Tight coupling between backend and frontend Poor tooling support compared to modern frontend stacks It feels like building a car from raw metal just to drive from point A to point B. Odoo ORM Odoo’s ORM is not a typical ORM. It implements: A custom inheritance system (instead of using Python’s built-in one) Its own dependency injection mechanism A query builder Caching layers (LRU) Model extension via monkey-patching While powerful, this system is extremely complex and hard to reason about. Debugging model behavior often feels like navigating invisible layers of magic. WebSocket Implementation Instead of using a mature real-time framework, Odoo implements its WebSocket handling with very low-level logic, sometimes in surprisingly small and dense files. A single comment from the codebase summarizes this approach better than words ever could: The “Odoo Is Old” Argument A common defense of Odoo’s architecture is that “it’s an old system” — originally developed around 2005 using Python 2. However, this argument no longer holds. Odoo was largely rewritten from scratch around 2017 to support Python 3. At that time, many excellent frameworks already existed and had solved the same problems more cleanly, while continuing to evolve without breaking their ecosystems. Today, even small changes in Odoo’s core can break custom modules unless they are limited to simple CRUD models with minimal dependencies on core behavior. Final Thoughts Odoo is a powerful product and a successful business platform. But from a software engineering perspective, many of its design decisions prioritize control and internal consistency over maintainability, clarity, and developer experience . If you work with Odoo long enough, you stop asking “why does it work this way?” and start asking “how do I survive this upgrade?” Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse Boga Posted on Jan 12 Odoo Core and the Cost of Reinventing Everything # python # odoo # qweb # owl Hello, this is my first blog post ever. I’d like to share my experience working with Odoo , an open-source Enterprise Resource Planning (ERP) system, and explain why I believe many of its architectural choices cause unnecessary complexity. Odoo is a single platform that provides many prebuilt modules (mini-applications) that most companies need. For example, almost every company requires a Human Resources system to manage employee details, leaves, attendance, contracts, resignations, and more. Beyond HR, companies also need purchasing, inventory, accounting, authentication, authorization, and other systems. Odoo bundles all of these tightly coupled systems into a single installation. On paper, this sounds great — and from a business perspective, it often is. From a technical perspective , however, things get complicated very quickly. Odoo Core Components Below are the main Odoo components, ranked from least complex to most complex, and all largely developed in-house instead of relying on existing mature frameworks: Odoo HTTP Layer JSON-RPC Website routing Odoo Views XML transformed into Python and JavaScript Odoo ORM Custom inheritance system Query builder Dependency injection Caching layers Cache System Implemented from scratch WebSocket Implementation Very low-level handling Odoo HTTP Layer Odoo is not built on a standard Python web framework like Django or Flask. Instead, it implements its own HTTP framework on top of Werkzeug (a WSGI utility library). This HTTP layer introduces its own abstractions, request lifecycle, routing, and serialization logic, including JSON-RPC and website controllers. While technically impressive, it reinvents many problems that have already been solved — and battle-tested — by existing frameworks. Odoo Views In my opinion, this is one of the most problematic parts of Odoo. Instead of using standard frontend technologies, Odoo relies heavily on XML-based views . These XML files are sent to the browser and then transformed using Abstract Syntax Tree (AST) analysis into JavaScript. In other contexts (like the website), the XML may be converted into Python code and sometimes back into JavaScript again. This creates: High cognitive overhead Difficult debugging Tight coupling between backend and frontend Poor tooling support compared to modern frontend stacks It feels like building a car from raw metal just to drive from point A to point B. Odoo ORM Odoo’s ORM is not a typical ORM. It implements: A custom inheritance system (instead of using Python’s built-in one) Its own dependency injection mechanism A query builder Caching layers (LRU) Model extension via monkey-patching While powerful, this system is extremely complex and hard to reason about. Debugging model behavior often feels like navigating invisible layers of magic. WebSocket Implementation Instead of using a mature real-time framework, Odoo implements its WebSocket handling with very low-level logic, sometimes in surprisingly small and dense files. A single comment from the codebase summarizes this approach better than words ever could: The “Odoo Is Old” Argument A common defense of Odoo’s architecture is that “it’s an old system” — originally developed around 2005 using Python 2. However, this argument no longer holds. Odoo was largely rewritten from scratch around 2017 to support Python 3. At that time, many excellent frameworks already existed and had solved the same problems more cleanly, while continuing to evolve without breaking their ecosystems. Today, even small changes in Odoo’s core can break custom modules unless they are limited to simple CRUD models with minimal dependencies on core behavior. Final Thoughts Odoo is a powerful product and a successful business platform. But from a software engineering perspective, many of its design decisions prioritize control and internal consistency over maintainability, clarity, and developer experience . If you work with Odoo long enough, you stop asking “why does it work this way?” and start asking “how do I survive this upgrade?” Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse eachampagne Posted on Nov 17, 2025 • Edited on Dec 6, 2025 Garbage Collection # computerscience # performance # programming It’s easy to forget, while working in the abstract in terms of functions and algorithms, that the memory our programs depend on is real . The values we use in our programs actually exist on the hardware at specific addresses. If we don’t keep track of where we’ve stored data, we run the risk of overwriting something important and getting the wrong information when we go to look it up again. On the other hand, if we’re too guarded about protecting our data, even after we’re finished with it, we waste memory that the program could better use on other tasks. Most programming languages today implement garbage collection to automate periodically releasing memory we no longer need. The garbage collector cannot predict exactly which values will be used again by our program, but it can find some that cannot due to no longer having any way to use them, and safely free them. Garbage Collection Algorithms Reference Counting The simplest algorithm is just to keep a count of references to a piece of memory. If the number of references ever reaches zero, that memory can no longer be reached and can be safely disposed of. However, this strategy fails with circular references. If two objects, for example, reference each other, their reference counts with never reach zero, even if they are otherwise inaccessible from the main program. Tracing Tracing (usually mark-and-sweep), is a more sophisticated approach to memory management. Starting from some defined root(s), the garbage collector visits every piece of memory accessible from either the root or its descendants, marking that memory as still reachable. Any memory not traversed is unreachable and is garbage collected. This avoids the problem of circular references “trapping” memory, since the cycle will not be reached from the main memory graph. However, this approach has more overhead than the reference counting strategy. Many garbage collectors reduce the overhead of mark-and-search by having two (or more) “generations” of allocations. The generational hypothesis states that most allocations die young (think how many variables you use once in a for loop and never again), but those that survive are much more likely to survive a long time. Thus, the pool of young allocations (the “nursery”) is garbage collected frequently, while the old (“tenured”) pool is checked less often. It’s possible to combine both strategies in a hybrid collector. For example, Python uses reference counting as its primary algorithm, then uses a mark-and-sweep pass over the (now smaller) pool of allocated memory to find and eliminate circular references. The Downsides of Garbage Collection Of course, the garbage collector itself introduces some overhead. Depending on the implementation, it may bring the program to a halt while it scans and frees data or defragments the remaining memory. It is also impossible to create a perfectly efficient garbage collector due to the inherent uncertainty in which values will be used again. Other Approaches to Memory Management There are alternatives to garbage collection. A few languages, such as C and C++, require the programmer to manage memory manually (although you can add garbage collectors to both languages yourself if you wish), both while allocating memory to new variables and when deciding when to free memory. Manual memory management avoids the overhead of garbage collection, but adds to program complexity, since this now must be handled by the code itself rather than happening in the background. This also gives the programmer many opportunities to make mistakes , from creating floating pointers by freeing too soon to leaking memory by freeing too late or not at all, to say nothing of the difficulty of using pointers themselves. Rust takes a third option and introduces the concept of “ ownership ” – only one variable can own a piece of data at a time, and that data is released as soon as its owner goes out of scope. This eliminates the need for garbage collection at runtime, as well with its associated performance costs. However, the programmer has to keep track of ownership and borrowing of data, which limits how data can be read or changed at certain points of the program. This requires thinking in a different way from other languages, since some familiar patterns simply won’t compile, and increases Rust’s learning curve sharply. Garbage Collection in JavaScript JavaScript follows the majority of programming languages in using a garbage collector. However, the garbage collector itself is implemented and run by the JavaScript engine, not the script we write ourselves, so implementation varies slightly across engines. However, the general principles are the same. Modern JavaScript libraries all use a mark-and-sweep algorithm with the global object as the algorithm’s root. Since I regularly use Firefox and Node, I’ll look at their engines in a bit more detail. SpiderMonkey , the engine used by Firefox, applies the principle of generational collection, dividing allocations into young and old. It attempts to garbage collect incrementally to avoid long pauses, and runs parts of garbage collection in parallel with itself or concurrently with the main thread when possible. The V8 engine’s Orinoco garbage collector , has three generations: nursery, young, and old, and claims (as of 2019) to be a “mostly parallel and concurrent collector with incremental fallback.” V8 also brags about interweaving garbage collection into the idle time between drawing frames when possible, minimizing the time spent forcing JavaScript execution to pause. Based only on these descriptions, V8’s garbage collector seems a bit more advanced, perhaps because V8 used by Chromium-based browsers in addition to Node.js and thus has more support. However, they seem to have independently converged to similar architectures. The serious demands to provide a smooth user experience means that browser-based garbage collectors must be efficient and eliminate as much overhead as possible, because, as the Node guide to tracing garbage collection neatly summarizes, “ when GC is running, your code is not. ” I admit I’ve rather taken memory management for granted, since most of the languages I’ve studied have garbage collectors. I’ve been fascinated by Rust for years but haven’t managed to wrap my head around its ownership and borrowing rules. (Maybe this is the time it will finally click for me.) But if I struggle with memory management when the compiler itself is looking out for me, I’m not sure how I’d fare in a manual memory management scheme without guardrails. So for now, I’m very grateful to garbage collectors everywhere for making my life easier. The Memory Management Reference was invaluable while researching this blog post, in addition to many other engine- and language-specific references (linked throughout the text).

Report Abuse Flo Posted on Jan 12 I tried to capture system audio in the browser. Here's what I learned. # webdev # javascript # learning # api I'm building LiveSuggest, a real-time AI assistant that listens to your meetings and gives you suggestions as you talk. Simple idea, right? Turns out, capturing audio from a browser tab is... complicated. The good news Chrome and Edge support it. You use getDisplayMedia , the same API for screen sharing, but with an audio option: const stream = await navigator . mediaDevices . getDisplayMedia ({ video : true , audio : { systemAudio : ' include ' } }); Enter fullscreen mode Exit fullscreen mode The user picks a tab to share, checks "Share tab audio", and boom — you get the audio stream. Works great for Zoom, Teams, Meet, whatever runs in a browser tab. The bad news Firefox? Implements getDisplayMedia but completely ignores the audio part. No error, no warning. You just... don't get audio. Safari? Same story. The API exists, audio doesn't. Mobile browsers? None of them support it. iOS, Android, doesn't matter. So if you're building something that needs system audio, you're looking at Chrome/Edge desktop only. That's maybe 60-65% of your potential users. What I ended up doing I detect the browser upfront and show a clear message: "Firefox doesn't support system audio capture for meetings. Use Chrome or Edge for this feature. Microphone capture is still available." No tricks, no workarounds. Just honesty. Users appreciate knowing why something doesn't work rather than wondering if they did something wrong. For Firefox/Safari users, the app falls back to microphone-only mode. It's not ideal for capturing both sides of a conversation, but it's better than nothing. The annoying details A few things that wasted my time so they don't waste yours: You have to request video. Even if you only want audio. video: true is mandatory. I immediately stop the video track after getting the stream, but you can't skip it. The "Share tab audio" checkbox is easy to miss. Chrome shows it in the sharing dialog, but it's not checked by default. If your user doesn't check it, you get a stream with zero audio tracks. No error, just silence. The stream can die anytime. User clicks "Stop sharing" in Chrome's toolbar? Your stream ends. You need to listen for the ended event and handle it gracefully. Was it worth it? Absolutely. For the browsers that support it, capturing tab audio is a game-changer. You can build things that weren't possible before — meeting assistants, live translators, accessibility tools. Just go in knowing that you'll spend time on browser detection and fallbacks. That's the web in 2025. If you're curious about what I built, check out LiveSuggest . And if you've found better workarounds for Firefox/Safari, I'd love to hear about them in the comments.

Who wins? # webdev # css # javascript # react Introduction In modern React application development, there are many approaches to organizing application styles. One of the popular ways of such an organization is the CSS-in-JS approach (in the article we will use styled-components as the most popular solution) and CSS Modules. In this article, we will try to answer the question: which is better CSS-in-JS or CSS Modules ? So let's get back to basics. When a web page was primarily set for storing textual documentation and didn't include user interactions, properties were introduced to style the content. Over time, the web became more and more popular, sites got bigger, and it became necessary to reuse styles. For these purposes, CSS was invented. Cascading Style Sheets. Cascading plays a very important role in this name. We write styles that lay like a waterfall over the hollows of our document, filling it with colors and highlighting important elements. Time passed, the web became more and more complex, and we are facing the fact that the styles cascade turned into a problem for us. Distributed teams, working on their parts of the system, combining them into reusable modules, assemble an application from pieces, like Dr. Frankenstein, stitching styles into one large canvas, can get the sudden result... Due to the cascade, the styles of module 1 can affect the display of module 3, and module 4 can make changes to the global styles and change the entire display of the application in general. Developers have started to think of solving this problem. Style naming conventions were created to avoid overlaps, such as Yandex's BEM or Atomic CSS. The idea is clear, we operate with names in order to get predictability, but at the same time to prevent repetitions. These approaches were crashed of the rocks of the human factor. Anyway, we have no guarantee that the developer from team A won't use the name from team C. The naming problem can only be solved by assigning a random name to the CSS class. Thus, we get a completely independent CSS set of styles that will be applied to a specific HTML block and we understand for sure that the rest of the system won't be affected in any way. And then 2 approaches came onto the stage to organize our CSS: CSS Modules and CSS-in-JS . Under the hood, having a different technical implementation, and in fact solving the problem of atomicity, reusability, and avoiding side effects when writing CSS. Technically, CSS Modules transforms style names using a hash-based on the filename, path, style name. Styled-components handles styles in JS runtime, adding them as they go to the head HTML section (<head>). Approaches overview Let's see which approach is more optimal for writing a modern web application! Let's imagine we have a basic React application: import React , { Component } from ' react ' ; import ' ./App.css ' ; class App extends Component { render () { return ( < div className = "title" > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode CSS styles of this application: .title { padding : 20px ; background-color : #222 ; text-align : center ; color : white ; font-size : 1.5em ; } Enter fullscreen mode Exit fullscreen mode The dependencies are React 16.14 , react-dom 16.14 Let's try to build this application using webpack using all production optimizations. we've got uglified JS - 129kb separated and minified CSS - 133 bytes The same code in CSS Modules will look like this: import React , { Component } from ' react ' ; import styles from ' ./App.module.css ' ; class App extends Component { render () { return ( < div className = { styles . title } > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 129kb separated and minified CSS - 151 bytes The CSS Modules version will take up a couple of bytes more due to the impossibility of compressing the long generated CSS names. Finally, let's rewrite the same code under styled-components: import React , { Component } from ' react ' ; import styles from ' styled-components ' ; const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ` ; class App extends Component { render () { return ( < Title > React application title </ Title > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 163kb CSS file is missing The more than 30kb difference between CSS Modules and CSS-in-JS (styled-components) is due to styled-components adding extra code to add styles to the <head> part of the HTML document. In this synthetic test, the CSS Modules approach wins, since the build system doesn't add something extra to implement it, except for the changed class name. Styled-components due to technical implementation, adds dependency as well as code for runtime handling and styling of <head>. Now let's take a quick look at the pros and cons of CSS-in-JS / CSS Modules. Pros and cons CSS-in-JS cons The browser won't start interpreting the styles until styled-components has parsed them and added them to the DOM, which slows down rendering. The absence of CSS files means that you cannot cache separate CSS. One of the key downsides is that most libraries don't support this approach and we still can't get rid of CSS. All native JS and jQuery plugins are written without using this approach. Not all React solutions use it. Styles integration problems. When a markup developer prepares a layout for a JS developer, we may forget to transfer something; there will also be difficulty in synchronizing a new version of layout and JS code. We can't use CSS utilities: SCSS, Less, Postcss, stylelint, etc. pros Styles can use JS logic. This reminds me of Expression in IE6, when we could wrap some logic in our styles (Hello, CSS Expressions :) ). const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ${ props => props . secondary && css ` background-color: #fff; color: #000; padding: 10px; font-size: 1em; ` } ` ; Enter fullscreen mode Exit fullscreen mode When developing small modules, it simplifies the connection to the project, since you only need to connect the one independent JS file. It is semantically nicer to use <Title> in a React component than <h1 className={style.title}>. CSS Modules cons To describe global styles, you must use a syntax that does not belong to the CSS specification. :global ( .myclass ) { text-decoration : underline ; } Enter fullscreen mode Exit fullscreen mode Integrating into a project, you need to include styles. Working with typescript, you need to automatically or manually generate interfaces. For these purposes, I use webpack loader: @teamsupercell/typings-for-css-modules-loader pros We work with regular CSS, it makes it possible to use SCSS, Less, Postcss, stylelint, and more. Also, you don't waste time on adapting the CSS to JS. No integration of styles into the code, clean code as result. Almost 100% standardized except for global styles. Conclusion So the fundamental problem with the CSS-in-JS approach is that it's not CSS! This kind of code is harder to maintain if you have a defined person in your team working on markup. Such code will be slower, due to the fact that the CSS rendered into the file is processed in parallel, and the CSS-in-JS cannot be rendered into a separate CSS file. And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on. On the other hand, the CSS-in-JS approach can be a good solution for the Frontend team who deals with both markup and JS, and develops all components from scratch. Also, CSS-in-JS will be useful for modules that integrate into other applications. In my personal opinion, the issue of CSS cascading is overrated. If we are developing a small application or site, with one team, then we are unlikely to encounter a name collision or the difficulty of reusing components. If you faced with this problem, I recommend considering CSS Modules, as, in my opinion, this is a more optimal solution for the above factors. In any case, whatever you choose, write meaningful code and don't get fooled by the hype. Hype will pass, and we all have to live with it. Have great and interesting projects, dear readers!

For CSS-in-JS I find easier to reuse that code in a React Native project. My personal conclusion is that we are constantly trying to avoid CSS but at the end of the day, CSS will stay here forever.

But i ran into issues with styled components that I wouldn't have had with plain scss. So some things to think about: Styled components is a lot more overhead because all the styled components need to be complied into stylesheets and mounted to the head by javascript which is a blocking language. On SSR styled components get compiled into a ServerStyleSheet that then hydrate the react dom tree in the browser via the context api. So even then the mounting of styles only happens in the browser but the parsing of styles happens on the server - that is still a performance penalty and will slow down the page load. In some cases I had no issues with styled components but as my site grew and in complex cases I couldn't help but feel like it was slower, or didn't load as smoothly... and in a world where every second matters, this was a problem for me. Here is an article doing benchmarks on CSS vs CSS in JS: pustelto.com/blog/css-vs-css-in-js... I use nextjs, it is a pity they do not support component level css and we are forced to use css modules or styled components... where as with Nuxt component level scss is part of the package and you have the option on how you want the sites css to bundled - all in one file, split into their own files and some other nifty options. I hope nextjs sharped up on this.

Why not use SCSS and unique classNames: For example create a unique container className (name of the component) and nest all the other classNames under that unique container className. .home-page-guest { .nav {} .main {} .footer {} } Enter fullscreen mode Exit fullscreen mode < div className = " home-page-guest " > < div className = " nav " /> < div className = " main " /> < div className = " footer " /> < /div > Enter fullscreen mode Exit fullscreen mode Like comment: Like comment: 2 likes Like Comment button Reply Collapse Expand Cindy Vos Cindy Vos Cindy Vos Follow Tuff shed and light and strong enough Joined Sep 11, 2025 • Sep 15 '25 Dropdown menu Copy link Hide I bet you did Greg Like comment: Like comment: 1 like Like Comment button Reply Collapse Expand Hank Queston Hank Queston Hank Queston Follow Work CTO at Bonfire Joined May 25, 2021 • May 25 '21 Dropdown menu Copy link Hide I agreed, CSS Modules make a lot more sense to me over Styled Components, always have!

In this case you can't use Styled-components on sites that require a good SEO, becouse the mos important think here is the SEO and you cant sacrify it.

I've opted to use emotion's css utility exclusively and instructed my team to avoid using any of the styled component features. We've loved it but this was a few years ago. For newer projects I'm going with the css modules design. Also why does anyone care about sass anymore? With css variables and the css nesting module in the specification, you get the best parts of sass with vanilla css. The other features are just overkill for a css-module that should represent a single react component and thus nothing :global . Complicated sass directives and stuff are just overkill. Turn it into a react component and don't make any crazy css systems.

I've been using CSS modules for a short time now and I like it. Allows everything to be nicely compartmentalized. I also like that it gives more freedom to name classes in smaller chunks of CSS code.

"And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on." Not a single thing here is true. SCSS is the original syntax of the package, you can use Stylelint as well. There are a lot more "pros" which are not listed here. By working with JS you are opened to another world. I'll list some more "pros" from the top of my head: consume and validate your theme colors as pure JS object consume state/props and create dynamic CSS out of it you have plugins which can be a live savers in cases like RTL (right to left orientation). Whoever had to support an app/website with RTL will be magically saved by this plugin. You can create custom plugins to fix various problems, or make your own linting in your team project. you don't think about CSS class names and collision. I prefer to be focused on thinking about variable names in my JS only and not spending effort in the CSS as well when you break your visual habits you will realise that's it's easier to have your CSS in your JS file just the way you got used to have your HTML in your JS file (React) In these days CSS has become a monster. You have inheritance, mixins, variables, IF statements, loops etc. Sure they can be useful somewhere but I'm pretty sure that most of you just need to center that div. So in my personal opinion we should strive to keep CSS as simpler as possible (as with everything actually) and I think that Styled Components are kind of pushing you to do exactly that. Don't re-use CSS, re-use components! The only global things you should have are probably just the color theme and animations.

Report Abuse Mohammad-Idrees Posted on Jan 13 Contrast sync vs async failure classes using first principles # architecture # computerscience # systemdesign 1. Start from First Principles: What Is a “Failure Class”? A failure class is not: a bug a timeout an outage A failure class is: A category of things that can go wrong because of how responsibility, time, and state are structured So we ask: What must be true for correctness? What assumptions does the model silently make? What breaks when those assumptions are false? 2. Core Difference (One Sentence) Synchronous systems fail by blocking and cascading. Asynchronous systems fail by duplication, reordering, and invisibility. Everything else is a consequence. 3. Synchronous Systems — Failure Classes Definition (First Principles) A synchronous system assumes: “The caller waits while the callee finishes the work.” This couples: time availability correctness Failure Class 1: Blocking Amplification Question asked: What happens while the system waits? Reality: Threads blocked Connections held Memory retained Failure mode: Load increases → latency increases → throughput collapses This is not just “slow.” It is non-linear failure . Failure Class 2: Cascading Failure Question asked: What if a dependency slows down? Because everything is waiting: Agent slows → backend slows Backend slows → frontend retries Retries amplify load Failure mode: One slow dependency can take down the entire system Failure Class 3: Availability Coupling Question asked: Can the system function if the dependency is down? Answer in sync systems: No Failure mode: Partial outage becomes total outage Summary: Sync Failure Classes Category Root Cause Blocking Time is coupled Cascades Dependencies are inline Global outage Availability is transitive 4. Asynchronous Systems — Failure Classes Definition (First Principles) An async system assumes: “Work can finish later, possibly multiple times, possibly out of order.” This decouples time but removes guarantees . Failure Class 1: Duplicate Execution Question asked: What happens if work is retried? Reality: At-least-once delivery Worker crashes Message reprocessed Failure mode: Same logical action happens multiple times This breaks: Exactly-once semantics Idempotency assumptions Failure Class 2: Ordering Violations Question asked: What defines sequence? Reality: Queues don’t know business order Workers process independently Failure mode: Effects appear out of logical order For chat systems: Responses based on future messages Context corruption Failure Class 3: Completion Invisibility Question asked: How does the user know when work is done? Reality: No direct signal Polling or guessing Failure mode: Users wait blindly or see stale state Failure Class 4: Orphaned Work Question asked: What if the user disappears? Reality: Job keeps running Response stored but never consumed Failure mode: Wasted compute, leaked state Summary: Async Failure Classes Category Root Cause Duplication Retries Reordering Decoupled execution Invisibility No direct completion path Orphans Detached lifecycles 5. Side-by-Side Contrast (Mental Model) Dimension Synchronous Asynchronous Time Coupled Decoupled Failure style Blocking, cascades Duplication, disorder Availability All-or-nothing Partial Correctness risk Latency-based Logic-based Debugging Easier Harder 6. Deep Insight (This Is the Interview Gold) Synchronous systems fail loudly and immediately. Asynchronous systems fail quietly and later. Sync failures are obvious (timeouts, errors) Async failures are subtle (double writes, wrong order) 7. Why Neither Is “Better” From first principles: Sync systems protect causality but sacrifice availability Async systems protect availability but sacrifice causality Real systems exist to reintroduce the lost property : Async systems add idempotency, ordering, state machines Sync systems add timeouts, circuit breakers, fallbacks 8. One-Line Rule to Remember Sync breaks under load. Async breaks under ambiguity. If you want next, we can: Map these failure classes to real outages Show how streaming combines both failure types Practice identifying failure classes on a fresh system Tell me the next direction.

This post shows you what happens when you actually hit Hello World with 25 concurrent users on a cheap VPS. (Spoiler: It crashes). Here is how I fixed it. ## The Stack 🛠️ I chose Bun over Node.js for its startup speed and built-in tooling. Runtime: Bun Framework: ElysiaJS (Fastest Bun framework) Database: PostgreSQL (via Dokploy) ORM: Drizzle (Lightweight & Type-safe) Hosting: VPS with Dokploy (Docker Compose) The "Oh Sh*t" Moment 🚨 I deployed my first version. It worked fine for me. Then I ran a load test using k6 to simulate 25 virtual users browsing various feeds. k6 run tests/stress-test.js Enter fullscreen mode Exit fullscreen mode Result: ✗ http_req_failed................: 86.44% ✗ status is 429..................: 86.44% The server wasn't crashing, but it was rejecting almost everyone. Diagnosis I initially blamed Traefik (the reverse proxy). But digging into the code, I found the culprit was me . // src/index.ts // OLD CONFIGURATION . use ( rateLimit ({ duration : 60 _000 , max : 100 // 💀 100 requests per minute... GLOBAL per IP? })) Enter fullscreen mode Exit fullscreen mode Since my stress test (and likely any future NATed corporate office) sent all requests from a single IP, I was essentially DDOSing myself. The Fixes 🔧 1. Tuning the Rate Limiter I bumped the limit to 2,500 req/min . This prevents abuse while allowing heavy legitimate traffic (or load balancers). // src/index.ts . use ( rateLimit ({ duration : 60 _000 , max : 2500 // Much better for standard reliable APIs })) Enter fullscreen mode Exit fullscreen mode 2. Database Connection Pooling The default Postgres pool size is often small (e.g., 10 or 20). My VPS has 4GB RAM. PostgreSQL needs RAM for connections, but not that much. I bumped the pool to 80 connections . // src/db/index.ts const client = postgres ( process . env . DATABASE_URL , { max : 80 }); Enter fullscreen mode Exit fullscreen mode 3. Horizontal Scaling with Docker Node/Bun is single-threaded. A single container uses 1 CPU core effectivey. My VPS has 2 vCPUs. I added a replicas instruction to my docker-compose.dokploy.yml : api : build : . restart : always deploy : replicas : 2 # One for each core! Enter fullscreen mode Exit fullscreen mode This instantly doubled my throughput capacity. Traefik automatically load-balances between the two containers. The Final Result 🟢 Ran k6 again: ✓ checks_succeeded...: 100.00% ✓ http_req_duration..: p(95)=200.45ms ✓ http_req_failed....: 0.00% (excluding auth checks) Enter fullscreen mode Exit fullscreen mode 0 errors. 200ms latency. On a cheap VPS. Takeaway You don't need Kubernetes for a side project. You just need to understand where your bottlenecks are: Application Layer: Check your Rate Limits. Database Layer: Check your Connection Pool. Hardware: Use all your cores (Replicas). If you want to try the API, I published it on RapidAPI as Micro-Social API . https://rapidapi.com/ismamed4/api/micro-social Happy coding! 🚀 Top comments (1) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Who wins? # webdev # css # javascript # react Introduction In modern React application development, there are many approaches to organizing application styles. One of the popular ways of such an organization is the CSS-in-JS approach (in the article we will use styled-components as the most popular solution) and CSS Modules. In this article, we will try to answer the question: which is better CSS-in-JS or CSS Modules ? So let's get back to basics. When a web page was primarily set for storing textual documentation and didn't include user interactions, properties were introduced to style the content. Over time, the web became more and more popular, sites got bigger, and it became necessary to reuse styles. For these purposes, CSS was invented. Cascading Style Sheets. Cascading plays a very important role in this name. We write styles that lay like a waterfall over the hollows of our document, filling it with colors and highlighting important elements. Time passed, the web became more and more complex, and we are facing the fact that the styles cascade turned into a problem for us. Distributed teams, working on their parts of the system, combining them into reusable modules, assemble an application from pieces, like Dr. Frankenstein, stitching styles into one large canvas, can get the sudden result... Due to the cascade, the styles of module 1 can affect the display of module 3, and module 4 can make changes to the global styles and change the entire display of the application in general. Developers have started to think of solving this problem. Style naming conventions were created to avoid overlaps, such as Yandex's BEM or Atomic CSS. The idea is clear, we operate with names in order to get predictability, but at the same time to prevent repetitions. These approaches were crashed of the rocks of the human factor. Anyway, we have no guarantee that the developer from team A won't use the name from team C. The naming problem can only be solved by assigning a random name to the CSS class. Thus, we get a completely independent CSS set of styles that will be applied to a specific HTML block and we understand for sure that the rest of the system won't be affected in any way. And then 2 approaches came onto the stage to organize our CSS: CSS Modules and CSS-in-JS . Under the hood, having a different technical implementation, and in fact solving the problem of atomicity, reusability, and avoiding side effects when writing CSS. Technically, CSS Modules transforms style names using a hash-based on the filename, path, style name. Styled-components handles styles in JS runtime, adding them as they go to the head HTML section (<head>). Approaches overview Let's see which approach is more optimal for writing a modern web application! Let's imagine we have a basic React application: import React , { Component } from ' react ' ; import ' ./App.css ' ; class App extends Component { render () { return ( < div className = "title" > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode CSS styles of this application: .title { padding : 20px ; background-color : #222 ; text-align : center ; color : white ; font-size : 1.5em ; } Enter fullscreen mode Exit fullscreen mode The dependencies are React 16.14 , react-dom 16.14 Let's try to build this application using webpack using all production optimizations. we've got uglified JS - 129kb separated and minified CSS - 133 bytes The same code in CSS Modules will look like this: import React , { Component } from ' react ' ; import styles from ' ./App.module.css ' ; class App extends Component { render () { return ( < div className = { styles . title } > React application title </ div > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 129kb separated and minified CSS - 151 bytes The CSS Modules version will take up a couple of bytes more due to the impossibility of compressing the long generated CSS names. Finally, let's rewrite the same code under styled-components: import React , { Component } from ' react ' ; import styles from ' styled-components ' ; const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ` ; class App extends Component { render () { return ( < Title > React application title </ Title > ); } } Enter fullscreen mode Exit fullscreen mode uglified JS - 163kb CSS file is missing The more than 30kb difference between CSS Modules and CSS-in-JS (styled-components) is due to styled-components adding extra code to add styles to the <head> part of the HTML document. In this synthetic test, the CSS Modules approach wins, since the build system doesn't add something extra to implement it, except for the changed class name. Styled-components due to technical implementation, adds dependency as well as code for runtime handling and styling of <head>. Now let's take a quick look at the pros and cons of CSS-in-JS / CSS Modules. Pros and cons CSS-in-JS cons The browser won't start interpreting the styles until styled-components has parsed them and added them to the DOM, which slows down rendering. The absence of CSS files means that you cannot cache separate CSS. One of the key downsides is that most libraries don't support this approach and we still can't get rid of CSS. All native JS and jQuery plugins are written without using this approach. Not all React solutions use it. Styles integration problems. When a markup developer prepares a layout for a JS developer, we may forget to transfer something; there will also be difficulty in synchronizing a new version of layout and JS code. We can't use CSS utilities: SCSS, Less, Postcss, stylelint, etc. pros Styles can use JS logic. This reminds me of Expression in IE6, when we could wrap some logic in our styles (Hello, CSS Expressions :) ). const Title = styles . h1 ` padding: 20px; background-color: #222; text-align: center; color: white; font-size: 1.5em; ${ props => props . secondary && css ` background-color: #fff; color: #000; padding: 10px; font-size: 1em; ` } ` ; Enter fullscreen mode Exit fullscreen mode When developing small modules, it simplifies the connection to the project, since you only need to connect the one independent JS file. It is semantically nicer to use <Title> in a React component than <h1 className={style.title}>. CSS Modules cons To describe global styles, you must use a syntax that does not belong to the CSS specification. :global ( .myclass ) { text-decoration : underline ; } Enter fullscreen mode Exit fullscreen mode Integrating into a project, you need to include styles. Working with typescript, you need to automatically or manually generate interfaces. For these purposes, I use webpack loader: @teamsupercell/typings-for-css-modules-loader pros We work with regular CSS, it makes it possible to use SCSS, Less, Postcss, stylelint, and more. Also, you don't waste time on adapting the CSS to JS. No integration of styles into the code, clean code as result. Almost 100% standardized except for global styles. Conclusion So the fundamental problem with the CSS-in-JS approach is that it's not CSS! This kind of code is harder to maintain if you have a defined person in your team working on markup. Such code will be slower, due to the fact that the CSS rendered into the file is processed in parallel, and the CSS-in-JS cannot be rendered into a separate CSS file. And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on. On the other hand, the CSS-in-JS approach can be a good solution for the Frontend team who deals with both markup and JS, and develops all components from scratch. Also, CSS-in-JS will be useful for modules that integrate into other applications. In my personal opinion, the issue of CSS cascading is overrated. If we are developing a small application or site, with one team, then we are unlikely to encounter a name collision or the difficulty of reusing components. If you faced with this problem, I recommend considering CSS Modules, as, in my opinion, this is a more optimal solution for the above factors. In any case, whatever you choose, write meaningful code and don't get fooled by the hype. Hype will pass, and we all have to live with it. Have great and interesting projects, dear readers!

But i ran into issues with styled components that I wouldn't have had with plain scss. So some things to think about: Styled components is a lot more overhead because all the styled components need to be complied into stylesheets and mounted to the head by javascript which is a blocking language. On SSR styled components get compiled into a ServerStyleSheet that then hydrate the react dom tree in the browser via the context api. So even then the mounting of styles only happens in the browser but the parsing of styles happens on the server - that is still a performance penalty and will slow down the page load. In some cases I had no issues with styled components but as my site grew and in complex cases I couldn't help but feel like it was slower, or didn't load as smoothly... and in a world where every second matters, this was a problem for me. Here is an article doing benchmarks on CSS vs CSS in JS: pustelto.com/blog/css-vs-css-in-js... I use nextjs, it is a pity they do not support component level css and we are forced to use css modules or styled components... where as with Nuxt component level scss is part of the package and you have the option on how you want the sites css to bundled - all in one file, split into their own files and some other nifty options. I hope nextjs sharped up on this.

So the mos important think that we need to do is select the tools, libraries and technologies that fit better to the current project. In this case you can't use Styled-components on sites that require a good SEO, becouse the mos important think here is the SEO and you cant sacrify it.

I've opted to use emotion's css utility exclusively and instructed my team to avoid using any of the styled component features. We've loved it but this was a few years ago. For newer projects I'm going with the css modules design. Also why does anyone care about sass anymore? With css variables and the css nesting module in the specification, you get the best parts of sass with vanilla css. The other features are just overkill for a css-module that should represent a single react component and thus nothing :global . Complicated sass directives and stuff are just overkill. Turn it into a react component and don't make any crazy css systems.

"And the last fundamental flaw is the inability to use ready-made approaches and utilities, such as SCSS, Less and Stylelint, and so on." Not a single thing here is true. SCSS is the original syntax of the package, you can use Stylelint as well. There are a lot more "pros" which are not listed here. By working with JS you are opened to another world. I'll list some more "pros" from the top of my head: consume and validate your theme colors as pure JS object consume state/props and create dynamic CSS out of it you have plugins which can be a live savers in cases like RTL (right to left orientation). Whoever had to support an app/website with RTL will be magically saved by this plugin. You can create custom plugins to fix various problems, or make your own linting in your team project. you don't think about CSS class names and collision. I prefer to be focused on thinking about variable names in my JS only and not spending effort in the CSS as well when you break your visual habits you will realise that's it's easier to have your CSS in your JS file just the way you got used to have your HTML in your JS file (React) In these days CSS has become a monster. You have inheritance, mixins, variables, IF statements, loops etc. Sure they can be useful somewhere but I'm pretty sure that most of you just need to center that div. So in my personal opinion we should strive to keep CSS as simpler as possible (as with everything actually) and I think that Styled Components are kind of pushing you to do exactly that. Don't re-use CSS, re-use components! The only global things you should have are probably just the color theme and animations.

One-bit reference counting 3.2.4. Weighted reference counting 3. Recycling techniques ¶ There are many ways for automatic memory managers to determine what memory is no longer required. In the main, garbage collection relies on determining which blocks are not pointed to by any program variables. Some of the techniques for doing this are described briefly below, but there are many potential pitfalls, and many possible refinements. These techniques can often be used in combination. 3.1. Tracing collectors ¶ Automatic memory managers that follow pointers to determine which blocks of memory are reachable from program variables (known as the root set ) are known as tracing collectors. The classic example is the mark-sweep collector. 3.1.1. Mark-sweep collection ¶ In a mark-sweep collection, the collector first examines the program variables; any blocks of memory pointed to are added to a list of blocks to be examined. For each block on that list, it sets a flag (the mark) on the block to show that it is still required, and also that it has been processed. It also adds to the list any blocks pointed to by that block that have not yet been marked. In this way, all blocks that can be reached by the program are marked. In the second phase, the collector sweeps all allocated memory, searching for blocks that have not been marked. If it finds any, it returns them to the allocator for reuse. Five memory blocks, three of which are reachable from program variables. ¶ In the diagram above, block 1 is directly accessible from a program variable, and blocks 2 and 3 are indirectly accessible. Blocks 4 and 5 cannot be reached by the program. The first step would mark block 1, and remember blocks 2 and 3 for later processing. The second step would mark block 2. The third step would mark block 3, but wouldn’t remember block 2 as it is already marked. The sweep phase would ignore blocks 1, 2, and 3 because they are marked, but would recycle blocks 4 and 5. The two drawbacks of simple mark-sweep collection are: it must scan the entire memory in use before any memory can be freed; it must run to completion or, if interrupted, start again from scratch. If a system requires real-time or interactive response, then simple mark-sweep collection may be unsuitable as it stands, but many more sophisticated garbage collection algorithms are derived from this technique. 3.1.2. Copying collection ¶ After many memory blocks have been allocated and recycled, there are two problems that typically occur: the memory in use is widely scattered in memory, causing poor performance in the memory caches or virtual memory systems of most modern computers (known as poor locality of reference ); it becomes difficult to allocate large blocks because free memory is divided into small pieces, separated by blocks in use (known as external fragmentation ). One technique that can solve both these problems is copying garbage collection . A copying garbage collector may move allocated blocks around in memory and adjust any references to them to point to the new location. This is a very powerful technique and can be combined with many other types of garbage collection, such as mark-sweep collection. The disadvantages of copying collection are: it is difficult to combine with incremental garbage collection (see below) because all references must be adjusted to remain consistent; it is difficult to combine with conservative garbage collection (see below) because references cannot be confidently adjusted; extra storage is required while both new and old copies of an object exist; copying data takes extra time (proportional to the amount of live data). 3.1.3. Incremental collection ¶ Older garbage collection algorithms relied on being able to start collection and continue working until the collection was complete, without interruption. This makes many interactive systems pause during collection, and makes the presence of garbage collection obtrusive. Fortunately, there are modern techniques (known as incremental garbage collection ) to allow garbage collection to be performed in a series of small steps while the program is never stopped for long. In this context, the program that uses and modifies the blocks is sometimes known as the mutator . While the collector is trying to determine which blocks of memory are reachable by the mutator, the mutator is busily allocating new blocks, modifying old blocks, and changing the set of blocks it is actually looking at. Incremental collection is usually achieved with either the cooperation of the memory hardware or the mutator; this ensures that, whenever memory in crucial locations is accessed, a small amount of necessary bookkeeping is performed to keep the collector’s data structures correct. 3.1.4. Conservative garbage collection ¶ Although garbage collection was first invented in 1958, many languages have been designed and implemented without the possibility of garbage collection in mind. It is usually difficult to add normal garbage collection to such a system, but there is a technique, known as conservative garbage collection , that can be used. The usual problem with such a language is that it doesn’t provide the collector with information about the data types, and the collector cannot therefore determine what is a pointer and what isn’t. A conservative collector assumes that anything might be a pointer. It regards any data value that looks like a pointer to or into a block of allocated memory as preventing the recycling of that block. Note that, because the collector does not know for certain which memory locations contain pointers, it cannot readily be combined with copying garbage collection. Copying collection needs to know where pointers are in order to update them when blocks are moved. You might think that conservative garbage collection could easily perform quite poorly, leaving a lot of garbage uncollected. In practice, it does quite well, and there are refinements that improve matters further. 3.2. Reference counts ¶ A reference count is a count of how many references (that is, pointers) there are to a particular memory block from other blocks. It is used as the basis for some automatic recycling techniques that do not rely on tracing. 3.2.1. Simple reference counting ¶ In a simple reference counting system, a reference count is kept for each object . This count is incremented for each new reference, and is decremented if a reference is overwritten, or if the referring object is recycled. If a reference count falls to zero, then the object is no longer required and can be recycled. Reference counting is frequently chosen as an automatic memory management strategy because it seems simple to implement using manual memory management primitives. However, it is hard to implement efficiently because of the cost of updating the counts. It is also hard to implement reliably, because the standard technique cannot reclaim objects connected in a loop. In many cases, it is an inappropriate solution, and it would be preferable to use tracing garbage collection instead. Reference counting is most useful in situations where it can be guaranteed that there will be no loops and where modifications to the reference structure are comparatively infrequent. These circumstances can occur in some types of database structure and some file systems. Reference counting may also be useful if it is important that objects are recycled promptly, such as in systems with tight memory constraints. 3.2.2. Deferred reference counting ¶ The performance of reference counting can be improved if not all references are taken into account. In one important technique, known as deferred reference counting , only references from other objects are counted, and references from program variables are ignored. Since most of the references to the object are likely to be from local variables, this can substantially reduce the overhead of keeping the counts up to date. An object cannot be reclaimed as soon as its count has dropped to zero, because there might still be a reference to it from a program variable. Instead, the program variables (including the control stack ) are periodically scanned , and any objects which are not referenced from there and which have zero count are reclaimed. Deferred reference counting cannot normally be used unless it is directly supported by the compiler. It’s more common for modern compilers to support tracing garbage collectors instead, because they can reclaim loops. Deferred reference counting may still be useful for its promptness—but that is limited by the frequency of scanning the program variables. 3.2.3. One-bit reference counting ¶ Another variation on reference counting, known as the one-bit reference count , uses a single bit flag to indicate whether each object has either “one” or “many” references. If a reference to an object with “one” reference is removed, then the object can be recycled. If an object has “many” references, then removing references does not change this, and that object will never be recycled. It is possible to store the flag as part of the pointer to the object, so no additional space is required in each object to store the count. One-bit reference counting is effective in practice because most actual objects have a reference count of one. 3.2.4. Weighted reference counting ¶ Reference counting is often used for tracking inter-process references for distributed garbage collection . This fails to collect objects in separate processes if they have looped references, but tracing collectors are usually too inefficient as inter-process tracing entails much communication between processes. Within a process, tracing collectors are often used for local recycling of memory. Many distributed collectors use a technique called weighted reference counting , which reduces the level of communication even further. Each time a reference is copied, the weight of the reference is shared between the new and the old copies. Since this operation doesn’t change the total weight of all references, it doesn’t require any communication with the object. Communication is only required when references are deleted. © Copyright 2023, Ravenbrook Limited. Created using Sphinx 4.5.0. | 2026-01-13T08:49:11 |

Automatic memory management 1.7. More information 1. Overview ¶ Memory management is a complex field of computer science and there are many techniques being developed to make it more efficient. This guide is designed to introduce you to some of the basic memory management issues that programmers face. This guide attempts to explain any terms it uses as it introduces them. In addition, there is a Memory Management Glossary of memory management terms that gives fuller information; some terms are linked to the relevant entries. Memory management is usually divided into three areas, although the distinctions are a little fuzzy: Hardware memory management Operating system memory management Application memory management These are described in more detail below. In most computer systems, all three are present to some extent, forming layers between the user’s program and the actual memory hardware. The Memory Management Reference is mostly concerned with application memory management. 1.1. Hardware memory management ¶ Memory management at the hardware level is concerned with the electronic devices that actually store data. This includes things like RAM and memory caches . 1.2. Operating system memory management ¶ In the operating system, memory must be allocated to user programs, and reused by other programs when it is no longer required. The operating system can pretend that the computer has more memory than it actually does, and also that each program has the machine’s memory to itself; both of these are features of virtual memory systems. 1.3. Application memory management ¶ Application memory management involves supplying the memory needed for a program’s objects and data structures from the limited resources available, and recycling that memory for reuse when it is no longer required. Because application programs cannot in general predict in advance how much memory they are going to require, they need additional code to handle their changing memory requirements. Application memory management combines two related tasks: Allocation When the program requests a block of memory, the memory manager must allocate that block out of the larger blocks it has received from the operating system. The part of the memory manager that does this is known as the allocator . There are many ways to perform allocation, a few of which are discussed in Allocation techniques . Recycling When memory blocks have been allocated, but the data they contain is no longer required by the program, then the blocks can be recycled for reuse. There are two approaches to recycling memory: either the programmer must decide when memory can be reused (known as manual memory management ); or the memory manager must be able to work it out (known as automatic memory management ). These are both described in more detail below. An application memory manager must usually work to several constraints, such as: CPU overhead The additional time taken by the memory manager while the program is running. Pause times The time it takes for the memory manager to complete an operation and return control to the program. This affects the program’s ability to respond promptly to interactive events, and also to any asynchronous event such as a network connection. Memory overhead How much space is wasted for administration, rounding (known as internal fragmentation ), and poor layout (known as external fragmentation ). Some of the common problems encountered in application memory management are considered in the next section. 1.4. Memory management problems ¶ The basic problem in managing memory is knowing when to keep the data it contains, and when to throw it away so that the memory can be reused. This sounds easy, but is, in fact, such a hard problem that it is an entire field of study in its own right. In an ideal world, most programmers wouldn’t have to worry about memory management issues. Unfortunately, there are many ways in which poor memory management practice can affect the robustness and speed of programs, both in manual and in automatic memory management. Typical problems include: Premature frees and dangling pointers Many programs give up memory, but attempt to access it later and crash or behave randomly. This condition is known as a premature free , and the surviving reference to the memory is known as a dangling pointer . This is usually confined to manual memory management . Memory leak Some programs continually allocate memory without ever giving it up and eventually run out of memory. This condition is known as a memory leak . External fragmentation A poor allocator can do its job of giving out and receiving blocks of memory so badly that it can no longer give out big enough blocks despite having enough spare memory. This is because the free memory can become split into many small blocks, separated by blocks still in use. This condition is known as external fragmentation . Poor locality of reference Another problem with the layout of allocated blocks comes from the way that modern hardware and operating system memory managers handle memory: successive memory accesses are faster if they are to nearby memory locations. If the memory manager places far apart the blocks a program will use together, then this will cause performance problems. This condition is known as poor locality of reference . Inflexible design Memory managers can also cause severe performance problems if they have been designed with one use in mind, but are used in a different way. These problems occur because any memory management solution tends to make assumptions about the way in which the program is going to use memory, such as typical block sizes, reference patterns, or lifetimes of objects. If these assumptions are wrong, then the memory manager may spend a lot more time doing bookkeeping work to keep up with what’s happening. Interface complexity If objects are passed between modules, then the interface design must consider the management of their memory. A well-designed memory manager can make it easier to write debugging tools, because much of the code can be shared. Such tools could display objects, navigate links, validate objects, or detect abnormal accumulations of certain object types or block sizes. 1.5. Manual memory management ¶ Manual memory management is where the programmer has direct control over when memory may be recycled. Usually this is either by explicit calls to heap management functions (for example, malloc and free (2) in C ), or by language constructs that affect the control stack (such as local variables). The key feature of a manual memory manager is that it provides a way for the program to say, “Have this memory back; I’ve finished with it”; the memory manager does not recycle any memory without such an instruction. The advantages of manual memory management are: it can be easier for the programmer to understand exactly what is going on; some manual memory managers perform better when there is a shortage of memory. The disadvantages of manual memory management are: the programmer must write a lot of code to do repetitive bookkeeping of memory; memory management must form a significant part of any module interface; manual memory management typically requires more memory overhead per object; memory management bugs are common. It is very common for programmers, faced with an inefficient or inadequate manual memory manager, to write code to duplicate the behavior of a memory manager, either by allocating large blocks and splitting them for use, or by recycling blocks internally. Such code is known as a suballocator . Suballocators can take advantage of special knowledge of program behavior, but are less efficient in general than fixing the underlying allocator. Unless written by a memory management expert, suballocators may be inefficient or unreliable. The following languages use mainly manual memory management in most implementations, although many have conservative garbage collection extensions: Algol ; C ; C++ ; COBOL ; Fortran ; Pascal . 1.6. Automatic memory management ¶ Automatic memory management is a service, either as a part of the language or as an extension, that automatically recycles memory that a program would not otherwise use again. Automatic memory managers (often known as garbage collectors, or simply collectors) usually do their job by recycling blocks that are unreachable from the program variables (that is, blocks that cannot be reached by following pointers). The advantages of automatic memory management are: the programmer is freed to work on the actual problem; module interfaces are cleaner; there are fewer memory management bugs; memory management is often more efficient. The disadvantages of automatic memory management are: memory may be retained because it is reachable, but won’t be used again; automatic memory managers (currently) have limited availability. There are many ways of performing automatic recycling of memory, a few of which are discussed in Recycling techniques . Most modern languages use mainly automatic memory management: BASIC , Dylan , Erlang, Haskell, Java , JavaScript , Lisp , ML , Modula-3 , Perl , PostScript , Prolog , Python, Scheme , Smalltalk , etc. 1.7. More information ¶ For more detailed information on the topics covered briefly above, please have a look at the Memory Management Glossary . Books and research papers are available on many specific techniques, and can be found via our Bibliography ; particularly recommended are: Wilson (1994) , which is survey of garbage collection techniques; Wilson et al. (1995) , which is a survey of allocation techniques; and Jones et al. (2012) , which is a handbook covering all aspects of garbage collection. © Copyright 2023, Ravenbrook Limited.
