(optional) If you're using Highlight on the frontend for your application, make sure you've initialized it correctly and followed the fullstack mapping guide . 2 Install the Highlight Go SDK. Install the highlight-go package with go get . go get -u github.com/highlight/highlight/sdk/highlight-go 3 Initialize the Highlight Go SDK. highlight.Start starts a goroutine for recording and sending backend traces and errors. Setting your project id lets Highlight record errors for background tasks and processes that aren't associated with a frontend session. import ( "github.com/highlight/highlight/sdk/highlight-go" ) func main() { // ... highlight.SetProjectID("<YOUR_PROJECT_ID>") highlight.Start( highlight.WithServiceName("my-app"), highlight.WithServiceVersion("git-sha"), ) defer highlight.Stop() // ... } 4 Add the Highlight Echo error handler. highlightEcho.Middleware() provides a Go Echo middleware to automatically record and send errors to Highlight. import ( highlightEcho "github.com/highlight/highlight/sdk/highlight-go/middleware/echo" ) func main() { // ... e := echo.New() e.Use(highlightEcho.Middleware()) // ... } 5 Record custom errors. (optional) If you want to explicitly send an error to Highlight, you can use the highlight.RecordError method. highlight.RecordError(ctx, err, attribute.String("key", "value")) 6 Verify your errors are being recorded. Now that you've set up the Middleware, verify that the backend error handling works by consuming an error from your handler. This is as easy as having a route handler return an error. 7 Verify your backend logs are being recorded. Visit the highlight logs portal and check that backend logs are coming in. 8 Verify your backend traces are being recorded. Visit the highlight traces portal and check that backend traces are coming in. chi Quick Start Fiber Quick Start [object Object] | 2026-01-13T08:49:00 |

Report Abuse Om Shree Posted on Oct 17, 2025 Cognee: Building the Next Generation of Memory for AI Agents (OSS) # ai # tutorial # beginners # discuss I. Moving Beyond Simple Search: The RAG Challenge If you've built applications using Large Language Models (LLMs) , you've likely used Retrieval-Augmented Generation (RAG) . RAG is essentially giving the LLM context from your documents so it doesn't hallucinate. It works like this: when a user asks a question, the system finds the most semantically similar chunks of text in your data (using vectors) and passes those chunks to the LLM for an answer. However, standard RAG has a massive limitation: it has no structural memory . It can tell you what a document says, but it can't understand how different concepts are related across multiple documents. It can’t perform "multi-hop" reasoning (e.g., "Find the manager of the person who approved Project X"). For AI agents, this is a major problem. They need to remember context, link facts, and build on past interactions to act intelligently. RAG can’t do that, it only retrieves information in isolation. A good memory gives agents continuity and understanding, letting them connect ideas the way humans do. Cognee is designed to solve this. It’s an open-source ai memory that combines two powerful storage methods “ Vector Search and Knowledge Graphs ” to give your AI a truly structural and semantic memory, resulting in answers with up to 92.5% reported accuracy in complex scenarios. II. The Core Architecture: A Cognitive Blueprint Cognee's architecture is inspired by human cognition, separating its functionality into four distinct layers. This separation ensures modularity and clarity in the data flow. Layer Analogy Technical Function Ingestion Intake / Triage Ingests data (over 30 formats supported), normalizes it, and routes it to the processing pipelines ( cognify ). Memory Dynamic Memory Layers and Persistent Storage Cognifies and stores knowledge in three systems (Graph, Vector, Relational) for structural and semantic recall. Reasoning Analysis / Synthesis Retrieves context from the Memory Layer, analyzes relationships, and prepares the final prompt for the LLM. Action Output Takes the LLM's final response and delivers it to the user or executes an external task (e.g., an API call). For visualization and exploration, Cognee also has a built-in function that renders the generated knowledge graph directly. This is what a Cognee knowledge graph looks like, illustrating the complex web of interconnected entities and relationships it builds from your input data, forming the structural memory for AI agents. Cognee also offers a local UI that uses interactive notebooks to run cognee tasks, pipelines, and custom logic we will describe below.. III. The Triple-Store Secret: Why You Need Three Databases One of the core innovations of Cognee is its sophisticated storage system, which integrates three types of databases, each serving a critical, non-redundant function. 1. The Vector Store (Semantic Recall) Purpose : Stores data chunks as numerical representations (embeddings). What it provides : High-speed semantic similarity search. This lets the system find content based on meaning, even if the query uses different words. Supported Tech : Qdrant, Milvus, LanceDB, Redis and more. 2. The Graph Store (Structural Reasoning) Purpose : Stores entities (nodes) and their relationships (edges) extracted from the text. What it provides: Structural reasoning . This is the GraphRAG component. It allows the system to traverse non-linear relationships, essential for complex queries like organizational charts, causal chains, and dependencies. Supported Tech : Neo4j, Kuzu, FalkorDB, NetworkX and more. 3. The Relational Store (Source of Truth) Purpose : A traditional SQL-based system (using SQLAlchemy and Alembic). What it provides: Provenance and Auditability . It stores all metadata, tracks the original source of every data chunk, ensuring that any derived knowledge is explainable and verifiable. This is crucial for enterprise applications requiring data governance. The magic happens in Hybrid Search (part of the .search() operation), where the system queries the Vector Store for relevant content and the Graph Store for the contextual relationships simultaneously, resulting in a maximally rich and coherent prompt for the LLM. IV. The Developer Workflow: Operations and Data Modeling Cognee is primarily a Pythonic library (over Python codebase). It exposes a clean, asynchronous API defined by four core functional primitives. A. The Core Functional Operations (ECL Model) Operation Action Description .add() Ingestion (Extract) Takes your raw files (PDFs, code, databases) and performs initial cleaning and preparation. .cognify() Knowledge Generation (Cognify) The main processing step . It uses an LLM to automatically read the cleaned data, chunk it, extract all entities and relationships, and build the final Triple-Store Memory . .memify() Memory Refinement (New) Cognee's advanced pipeline that uses AI to infer implicit connections, rule patterns, and relationships that were not explicitly in the source data, significantly enriching reasoning capability. .search() Hybrid Retrieval Executes a query combining vector search and graph traversal to retrieve context or generate a high-quality RAG answer. Code Snippet Python: import cognee # 1. Add raw data (text, PDFs, etc.) await cognee.add("path_to_your_project_notes.pdf") # 2. Cognify it - Transform data into structured knowledge await cognee.cognify() #3. Memify it - Enhance memory await cognee.memify() # 4. Search semantically and using graph traversal results = await cognee.search("Who manages Project X?") print(results) Enter fullscreen mode Exit fullscreen mode B. The Atomic Unit of Knowledge: DataPoints (Pydantic Models) For developers, the DataPoint is the single most important conceptual unit. Think of it as the strongly-typed schema for all knowledge within Cognee. Pydantic Foundation: DataPoints are implemented as Pydantic models. This guarantees that all knowledge is structured, type-validated, and reliable as it moves through the asynchronous processing pipeline. Dual Role: A DataPoint can represent a document, a segmented chunk of text, a concept/entity, or even a relationship (edge) in the graph. Declarative Indexing: The most powerful feature is the metadata.index_fields key. This is a list that you, the developer, use to explicitly tell Cognee which specific fields should be converted to embeddings. Example: For a DocumentChunk object, you'd index the text field. For an Entity object, you might only index the name field to save cost and avoid semantic noise. This granular control over indexing significantly optimizes both embedding costs and search accuracy. C. The Advanced Search Engine: Optimizations and Awareness Cognee's .search() operation goes beyond hybrid retrieval through two advanced features: Temporal Awareness : By setting temporal_cognify=True during knowledge generation, the system constructs a time-aware graph. This allows for powerful queries that analyze trends, understand the evolution of concepts, and provide context based on historical development velocity. Continuous Feedback Loops : The system supports an auto-optimization feedback mechanism. By saving search interactions ( save_interaction=True ) and providing explicit feedback, the system incorporates user-validated relevance into the graph, ensuring that its memory continuously adapts to specific user preferences and needs over time. V. Primary Use Cases: Where Cognee Shines Cognee’s architecture makes it ideal for applications that demand high-quality, verifiable outputs: Deterministic AI Agents : By providing agents (e.g., those built with Agent Frameworks like LangGraph, CrewAI) with structured, semantic memory, you ensure their outputs are grounded in verifiable relationships, leading to more reliable, accurate results. The .memify() pipeline is key here, as it allows memory enrichment through custom logic for agent decision-making. Vertical AI Agents (For Business functions) : They are specialized systems for compliance, finance, or legal workflows. They require absolute accuracy and explainability. Cognee provides this through its knowledge graph, which encodes domain-specific rules and relationships, supports ontology for more structured data modeling. This structural memory enables the agent to perform multi-step workflow orchestration and make auditable, factual decisions, thus overcoming the limitations of standard, general-purpose RAG. Code Graph Generation : Cognee can ingest codebases and automatically map out dependencies, function calls, and structural relationships. This resulting Code Graph Context is necessary for building sophisticated code copilots that can reason over a large project's structure, not just its content. VI. Getting Started with Cognee For developers eager to try Cognee locally, here’s a quick setup guide to get started within minutes: Step 1 : Clone the repository git clone https://github.com/topoteretes/cognee.git cd cognee Enter fullscreen mode Exit fullscreen mode Step 2 : Set up the Environment uv sync Enter fullscreen mode Exit fullscreen mode Step 3 : Once dependencies are installed, you can activate the virtual environment and explore examples: source .venv/bin/activate cd examples Enter fullscreen mode Exit fullscreen mode Or you can start Cognee with: uv pip install cognee Enter fullscreen mode Exit fullscreen mode Step 4 : Add your OpenAI API key to your .env file: LLM_API_KEY="your_openai_api_key" Enter fullscreen mode Exit fullscreen mode Cognee uses OpenAI by default but you can configure other model providers following their guideline. This process initiates Cognee's local environment, loading all available modules, such as the ingestion, graph, and search layers. Step 5 : Explore the Core Workflow The following example illustrates how Cognee simplifies intricate memory systems into a clear, high-level API: import cognee # 1. Add raw data (text, PDFs, etc.) await cognee.add("meeting_notes.pdf") # 2. Cognify it - transform data into structured knowledge await cognee.cognify() # 3. Search semantically and using graph traversal results = await cognee.search("Who manages the data pipeline?") print(results) Enter fullscreen mode Exit fullscreen mode Cognee instantly constructs and organizes information from raw documents, enabling semantic queries without the need for a duct taped RAG pipeline. You can find an end to end notebook tutorial here . VII. Conclusion: The Shift from Retrieval to Reasoning Cognee represents a pivotal shift in how developers approach context engineering. It moves the focus from simple retrieval (finding keywords and similar vectors) to complex reasoning **(analyzing structured relationships) powered by dynamic memory layers. By providing a powerful, yet simple to use **Pythonic framework that incorporates graph-based memory, declarative data modeling via DataPoints , and robust observability tools, Cognee is a perfect toolkit for me and other devs for building production-grade AI systems. The latest features, including the advanced .memify() reasoning pipeline, Node Sets for organizing memory and search filtering, Temporal Awareness for evolutionary analysis, auto-optimization with feedback loops, and a local visualization UI, firmly position Cognee as the next generation of AI memory. For any developer building agents that need to operate with accuracy, context, and structural awareness in complex domains, exploring Cognee is an essential next step in moving beyond the limitations of first-generation RAG.

Location Campbell Joined Sep 26, 2025 • Oct 21 '25 Dropdown menu Copy link Hide That’s a solid approach. The combination of vector search with a knowledge graph feels like the missing piece for most RAG setups. I’ve seen similar issues where context gets lost between related documents or previous user sessions. In Vezlo, we’re testing something similar for SaaS knowledge bases — trying to link context across multiple data sources instead of just retrieving static chunks. Curious how Cognee handles updates when the underlying data changes — does the graph rebuild incrementally or from scratch?

Cognee's approach is designed to be highly efficient. When the underlying data changes, the knowledge graph does not rebuild from scratch. Instead, it updates incrementally, allowing for real-time changes without the need for a full re-index. This is a core part of our architecture, ensuring that the system remains scalable and responsive, even with large and frequently updated datasets. It's interesting to hear about what you're building at Vezlo. Linking context across multiple data sources is a crucial challenge, and it sounds like you're tackling it head-on. I'd love to connect and share notes on our respective approaches.

(optional) If you're using Highlight on the frontend for your application, make sure you've initialized it correctly and followed the fullstack mapping guide . 2 Install the Highlight Go SDK. Install the highlight-go package with go get . go get -u github.com/highlight/highlight/sdk/highlight-go 3 Initialize the Highlight Go SDK. highlight.Start starts a goroutine for recording and sending backend traces and errors. Setting your project id lets Highlight record errors for background tasks and processes that aren't associated with a frontend session. import ( "github.com/highlight/highlight/sdk/highlight-go" ) func main() { // ... highlight.SetProjectID("<YOUR_PROJECT_ID>") highlight.Start( highlight.WithServiceName("my-app"), highlight.WithServiceVersion("git-sha"), ) defer highlight.Stop() // ... } 4 Add the Highlight gqlgen error handler. highlight.NewGraphqlTracer provides a middleware you can add to your GraphQL handler to automatically record and send GraphQL resolver errors to Highlight. Calling .WithRequestFieldLogging() will also emit highlight logs for each graphql operation, giving you a wayto search across all graphql requests to your backend. import ( "github.com/highlight/highlight/sdk/highlight-go" ) func main() { // ... server := handler.New(...) // call with WithRequestFieldLogging() to emit highlight logs for each graphql operation // useful for tracing which graphql operations are called as part of which frontend sessions server.Use(highlight.NewGraphqlTracer("your-backend-service-name").WithRequestFieldLogging()) // capture panics emitted by graphql handlers in highlight server.SetRecoverFunc(highlight.GraphQLRecoverFunc()) // format logs on errors thrown by your graphql handlers server.SetErrorPresenter(highlight.GraphQLErrorPresenter("my-gql-service")) // ... } 5 Record custom errors. (optional) If you want to explicitly send an error to Highlight, you can use the highlight.RecordError method. highlight.RecordError(ctx, err, attribute.String("key", "value")) 6 Verify your errors are being recorded. Now that you've set up the Middleware, verify that the backend error handling works by consuming an error from your handler. This is as easy as having a route handler return an error.

https://tinyhack.com/2014/02/28/raspberry-pi-for-out-of-band-linux-pc-management/ | Raspberry Pi for Out of Band Linux PC management – Tinyhack.com --> Skip to content Tinyhack.com A hacker does for love what others would not do for money. Raspberry Pi for Out of Band Linux PC management Just a day before I left to Indonesia for my brother’s wedding, I got worried about my headless Linux PC server: it may freeze when I left it. It happened before because of kernel panic and hardware error, it can happen again. I want to be able to reset the PC in case of errors and to power it down in case the error was not recoverable (for example last year my disk drive went bad). Just a note before reading this: in case you just want to turn on or off a PC using raspberry PI: just use wake on LAN (WOL) to turn on your PC and SSH access to turn it off. Wake on LAN works most of the time, but it can not handle a PC that is not responding. I soldered 2 optocouplers that I have (4N25) to a small perfboard with a pin header . Then I use solderless breadboard cables to connect the board to Raspberry Pi, and to the PC power and reset button (so I can manually turn on/off using the power/reset button on the PC). Watch carefully about the + and – on the motherboard (PW is for power, and RES is for reset, note the polarity is important for the optocoupler, on the picture above: Red goes to + and Black goes to -): I could just have used one optocoupler to connect to the power button (the reset is not really necessary, because we can turn off and on the PC again to reset), but I just want to use the extra 4N25 that I have (it’s really cheap, 5.5 baht or around 17 cents USD). To reset the PC, I just set the GPIO pin to high for about one second, then set it low again. To power up the PC, I set the GPIO pin to high for about 5 seconds, and set it low again (the same can be used to forcefully power down the PC). Resetting and powering the PC is easy, the next task is to know what happened if the PC crashed. To do this, I need a serial connection. If my PC has a serial port and I have a USB to serial cable, then everything will be much easier, but since I don’t have a USB to serial cable, and my PC doesn’t have a serial port on the back, it gets a bit complicated. I still have a small board based on MAX3232CPE to convert from 3.3V serial to 5.0 V, so I plugged that board to Raspberry Pi and connected it directly to the PC motherboard. This page helped me in finding the pin names (I only need to connect RX, TX and GND). On the Raspberry side, I need to set up so that it will not use the serial port for kernel output and log in. You can follow the guide here . On the PC side, I need to activate serial output in three places: to accept login (getty), to get the kernel output (kernel parameters in grub), and in grub itself (to show the boot selection dialog). This guide for Debian works for me, but I was not able to see the GRUB output on screen when I connected my screen (I can only see the output on my serial console, but this was not a problem for me). I experimented a little bit with SGABios Hoping that I would be able to see BIOS output from my serial port. It didn’t work as expected. I can not see the initial BIOS screen, and I can not send a key to enter BIOS setting, but If I connect a keyboard and press a button to enter the BIOS, I can see the BIOS menu via serial port and I can interact with it. Here are the steps that I tried to get the BIOS serial output: I downloaded the BIOS for my motherboard (an AWARD BIOS). Then on a windows machine, I modified the BIOS using CBROM cbrom bios.bin /isa sgabios.bin . Then I flashed the BIOS from Linux using Flashrom . I didn’t solve the BIOS problem due to time constraint. There are several solutions that I can think of to solve this: one is to use CoreBoot (but unfortunately my motherboard is not supported by coreboot), another one is to try to do more hacking on the BIOS (maybe removing the VGA ROM to force the output to serial port) and the other one is to simulate a keypress to enter BIOS. The first two methods may not be portable across BIOS, but the last one should be portable. The key simulation can be done by simulating a PS2 device (using bitbanging on Raspberry Pi), or USB HID device. A super simple USB HID device can be made by using V-USB library (you can see this as an example ). Just a few hours before I left, I have an idea to connect a temperature sensor just to see if the temperature around the PC case is too high. We are entering the summer here in Chiang Mai and the outside temperature is getting higher every day (from November to beginning of February, the temperature was around 8-20 Celcius, and now it is around 17-37 Celcius). It was quite easy to add the temperature sensor, I just use the guide and driver from adafruit . Next time I may add an infrared LED on the Raspberry Pi to turn on the Air Conditioner when it gets really hot. Having everything setup: nothing happened while I was away. The PC was running nicely (and I can access the PC via SSH and the serial console).

(optional) If you're using Highlight on the frontend for your application, make sure you've initialized it correctly and followed the fullstack mapping guide . 2 Install the highlight-io python package. Download the package from pypi and save it to your requirements. If you use a zip or s3 file upload to publish your function, you will want to make sure highlight-io is part of the build. poetry add highlight-io # or with pip pip install highlight-io 3 Initialize the Highlight SDK. Setup the SDK with instrument_logging disabled, while passing the highlight logging handler to loguru . instrument_logging=False must be passed to make sure the loguru handler does not collide with built-in logging instrumentation. import highlight_io H = highlight_io.H("<YOUR_PROJECT_ID>", instrument_logging=False) 4 Use loguru! Logs are reported automatically from loguru logging methods. Visit the highlight logs portal and check that backend logs are coming in. import highlight_io from loguru import logger H = highlight_io.H( "<YOUR_PROJECT_ID>", instrument_logging=False, service_name="my-app", service_version="git-sha", environment="production", ) logger.add( H.logging_handler, format="{message}", level="INFO", backtrace=True, serialize=True, ) def main(): logger.debug("That's it, beautiful and simple logging!", nice="one") context_logger = logger.bind(ip="192.168.0.1", user="someone") context_logger.info("Contextualize your logger easily") 5 Verify your backend logs are being recorded. Visit the highlight logs portal and check that backend logs are coming in. Google Cloud Functions Python App [object Object] | 2026-01-13T08:49:01 |

Browse the directory Faster builds for everyone Get started jack @ jackw_xyz you wanna see some real speed? Building and releasing a complete nextjs app in 1m3s (with help from @depotdev - insane 16s build and push thanks to caching) nacho @ ignacioaal ok @depotdev is awesome! got my build & push from 30 mins to 4 and it will be about 12 seconds when cached *chef kiss* Dan Loewenherz @ dwlz Just want to give a public shoutout to @depotdev . Since migrating from the default GitHub actions runner, our Docker image build times have literally been cut in half. Super impressive. So worth it. We are very happy customers. 😀 Shubham @ ShubhamInTech qemu emulations & buildkit made our arm builds really slow! tried out @depotdev and saw instant 10x faster builds at @formbricks 🚀 Mike Turck @ turckalicious we've found @depotdev to be incredible for reducing our own build times by >10x, from 8 min to 20s in one case Aaron @ aaronbatilo I build 3 react apps, and 7 Golang binaries + golang tests on every single commit -- all in about 30 seconds total thanks to some very precise docker context management, docker run cache mounts, and the incredible caches provided by @depotdev . All in a single `depot bake` command Matthieu Napoli @ matthieunapoli I am blown away by @depotdev , it's making the bref runtimes pipeline finally usable "docker build" becomes "depot build" in GitHub Actions and: - fast cross-platform builds (e.g. ARM) - everything is cached aggressively 10 to 20 times faster builds! Vlad Ionescu (he/him) @ iamvlaaaaaaad "How do these competitors of ours move so fast?! They fix bugs in hours instead of days, they develop new features in days instead of weeks, and their sales cycle is weeks instead of months!?!" Pro-tip: build a developer experience team that tries out new tools like @depotdev 😉 Nick @ NickZelei Just switched all of my multi-platform container builds over to using depot.dev . No cache github aciton build was 30m+. Cached was ~8m. Initial depot build (no cache): 3m. Amazing. Aidan W Steele @ __steele Building a container on my laptop: 19m40s, slow, makes me want to cry. Building it on @depotdev : 4m42s, speedy, makes me smile. But doesn't heat up my room enough, so I have to wear a jumper. Krishnan Chandra @ krishnanc_ Depot has been fantastic for us! We managed to get our build times down from ~8.5 minutes to ~30 seconds using the caching and cross-platform builds out of the box 😀 Luis Lavena @ luislavena Pushed a new build of my @CrystalLanguage container image (hydrofoil-crystal) with native arm64 support! 🥳 🚀 Thanks to @depotdev for making it easier (and faster!) to build ARM container images! 😊 Dan Manges @ dan_manges We switched to @depotdev for building our docker images at @rwx_research . Our build times are twice as fast and integration was impressively easy with their support for GitHub's OIDC token. It's easy to spot when we switched in our CI analytics. moon @ tothemoonrepo Amazing work. Depot really is a game changer. Your builds have never been this quick.

Help > Writing, Editing and Scheduling Writing, Editing and Scheduling In this article The Editor Drafting and publishing a post: Scheduling a post: Creating a Series Cross-posting Content Helpful Resources DEV Editor guide Markdown Cheatsheet Best Practices for Writing on DEV Guidelines for Avoiding Plagiarism on DEV Guidelines for AI-assisted Articles on DEV Common Questions Q: How do I set a canonical URL on my post? Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content. Helpful Resources Below you'll find various resources we recommend for better understanding DEV's writing policies and tools. DEV Editor guide A quick guide that provides you with technical tips for using the DEV Editor and our brand of Markdown. You can also find it by clicking the "?" page in the editor .

Guidelines for AI-assisted Articles on DEV These guidelines detail our requirements for properly labelling AI-assisted content on DEV. Please don't hesitate to report any content that is written with AI-assistance if it isn't following these guidelines. Common Questions Q: How do I set a canonical URL on my post? In the post editor, click the hexagon icon in the bottom left-hand corner beside "save draft" and you'll see an input box to designate a Canonical URL. Note: if you are using the Basic Markdown editor you must add a line for it inside the triple dashes (aka Front Matter), like so: --- title: published: false tags: canonical_url: <https://mycoolsite.com/my-post> --- Q: How do I set a cover image for my post? If using the Rich + Markdown editor, then click the "Add a cover image" button above the title of the post. If using the Basic Markdown editor, include cover_image: [url] in the front matter of your post. Note: you may change your editor type from your settings . Q: Do I own the articles that I publish? Yes, you own the rights to the content you create and post on dev.to and you have the full authority to post, edit, and remove your content as you see fit. Q: Can I cross-post something I've already written on my own blog or Medium? Absolutely, as long as you have the rights you need to do so! And if it's of high quality, we'll feature it. Q: Can I use profanity in my posts? We don't disallow profanity in general, but we do have an internal policy of not promoting posts that have profanity in the title, so you might want to keep that in mind. If your profanity is targeted at individuals or hateful, then it would cross the lines of what's acceptable via our Code of Conduct and we may take necessary action to remove you content. Q: Why has my post been removed? Your post is subject to removal at the discretion of the moderators if they believe it does not meet the requirements of our Code of Conduct . If you think we may have made a mistake, please email us at support@dev.to . Q: Will you put ads on my posts' pages? It's possible. We do allow organizations to purchase advertisements with DEV.

(" DEV ," " we ," or " us ") collects, use, and discloses your personal information. What's With the Defined Terms? You'll notice that some words appear in quotes in this Privacy Policy. They're called "defined terms," and we use them so that we don't have to repeat the same language again and again. They mean the same thing in every instance, to help us make sure that this Privacy Policy is consistent. We've included the defined terms throughout because we want it to be easy for you to read them in context. 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? 2. PERSONAL INFORMATION WE COLLECT 3. HOW WE USE YOUR INFORMATION 4. HOW WE DISCLOSE YOUR INFORMATION 5. YOUR PRIVACY CHOICES AND RIGHTS 6. INTERNATIONAL DATA TRANSFERS 7. RETENTION OF PERSONAL INFORMATION 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS 10. CHILDREN'S INFORMATION 11. OTHER PROVISIONS 12. CONTACT US 1. WHAT DOES THIS PRIVACY POLICY APPLY TO? This Privacy Policy applies to personal information processed by us, including on our websites, mobile applications, and other online or offline offerings — basically anything we do. To make this Privacy Policy easier to read, our websites, mobile applications, and other offerings are all collectively called the " Services. " Beyond this Privacy Policy, your use of the Services is subject to our DEV Community Terms and our Forem Terms. The Services include both our own community forum at https://www.dev.to (the " DEV Community ") and the open source tool we provide called " Forem ," available at https://www.forem.com which allows our customers to create and operate their own online forums. We collect personal information from two categories of people: (1) our customers, who use Forem and our hosting services to run and host their own forums (we'll call them " Forem Operators "), and (2) the people who interact with DEV-hosted forums, including forums provided by Forem Operators utilizing Forem and separately our own DEV Community (we'll call them " Users "). An Important Note for Users Since we provide hosting services for Forem Operators, technically we also process your information on their behalf. That processing is governed by the contracts that we have in place with each Forem Operator, not this Privacy Policy. In other words, when you share your data on a DEV-hosted forum operated by a Forem Operator, we at DEV are basically just the "pipes" — we process the data on behalf of the Forem Operator, but don't do anything with it ourselves beyond what we're required to do under our contract (and by law). So, if you post your information on a DEV-powered forum provided by a Forem Operator, that Forem Operator's privacy policy applies, and any questions or requests relating to your data on that service should be directed to that Forem Operator, not us. Likewise, if you use our mobile application, you may also interact with forums that use DEV's open-source tools but do all their hosting and data collection themselves. For those forums, we at DEV have no access to your data, so be sure to read the privacy policy of any third-party hosted forum before posting. 2. PERSONAL INFORMATION WE COLLECT The categories of personal information we collect depend on whether you're a User or Forem Operator, how you interact with us, our Services, and the requirements of applicable law. Breaking it down, we collect three types of information: (1) information that you provide to us directly, (2) information we obtain automatically when you use our Services, and (3) information we get about you from other sources (such as third-party services and organizations). More details are below. A. Information You Provide to Us Directly We may collect the following personal information that you provide to us. Account Creation (for Forem Operators): We'll require your name and email address to get started, as well as some details about the Forem you want to run, such as: whether you're running the Forem on your own behalf or as part of an organization, and details about the community you want to support (how big is it, what topics does it cover, where do members currently communicate, how/if the community earns money, whether the community is open, invite-only or paid, any existing social media accounts, etc.) You'll need to tell us a bit about your personal coding background, and you'll have the option to provide your DEV username as well, if you are a member of the DEV.to community. Account Creation (for Users) : We collect name and email address from users that create an account on DEV Community. For other forums created by Forem Operators using Forem, the Forem Operator determines what information is required for User account creation for their respective forums. Interactive Features (for Users) . Like any other social network, both we and other Users of our Services may collect personal information that you submit or make available through our interactive features (e.g., messaging and chat features, commenting functionalities, forums, blogs, posts, and other social media pages). While we do have private messages that are only between you and the person you're messaging (as well as us and the Forem Operator, as applicable), any information you provide using the public sharing features of the Services, such as the information you post to your public profile or the topics you follow is public, including to recruiters and prospective employers, and is not subject to any of the privacy protections we mention in this Privacy Policy except where legally required. Please exercise caution before revealing any information that may identify you in the real world to others. Purchases . If you buy stuff on our shop site https://shop.dev.to/ (as either a User or Forem Operator), or otherwise if you pay us in connection with your use of the Forem service, we may collect personal information and details associated with your purchases, including payment information. Any payments made via our Services are processed by third-party payment processors, such as Stripe, Shopify, and PayPal. We do not directly collect or store any payment card information entered through our Services, but may receive information associated with your payment card information (e.g., your billing details). Your Communications with Us (Users and Forem Operators) . We may collect personal information, such as email address, phone number, or mailing address when you request information about our Services, register for our newsletter or loyalty program, request customer or technical support, apply for a job, or otherwise communicate with us. Surveys . We may contact you to participate in surveys. If you decide to participate, you may be asked to provide certain information, which may include personal information (for example, your home address). Sweepstakes or Contests . We may collect personal information you provide for any sweepstakes or contests that we offer. In some jurisdictions, we are required to publicly share information of sweepstakes and contest winners. Conferences, Trade Shows, and Other Events . We may collect personal information from individuals when we attend conferences, trade shows, and other events. Business Development and Strategic Partnerships . We may collect personal information from individuals and third parties to assess and pursue potential business opportunities. Job Applications . We may post job openings and opportunities on our Services. If you reply to one of these postings by submitting your application, CV and/or cover letter to us, we will collect and use your information to assess your qualifications. B. Information Collected Automatically We may collect personal information automatically when you use our Services: Automatic Data Collection . We may collect certain information automatically when you use our Services, such as your Internet protocol (IP) address, user settings, MAC address, cookie identifiers, mobile carrier, mobile advertising and other unique identifiers, browser or device information, location information (including approximate location derived from IP address), and Internet service provider. We may also automatically collect information regarding your use of our Services, such as pages that you visit before, during and after using our Services, information about the links you click, the types of content you interact with, the frequency and duration of your activities, and other information about how you use our Services. In addition, we may collect information that other people provide about you when they use our Services, including information about you when they tag you in their posts. Cookies, Pixel Tags/Web Beacons, and Other Technologies . We, as well as third parties that provide content, advertising, or other functionality on our Services, may use cookies, pixel tags, local storage, and other technologies (" Technologies ") to automatically collect information through your use of our Services. Cookies . Cookies are small text files placed in device browsers that store preferences and facilitate and enhance your experience. Pixel Tags/Web Beacons . A pixel tag (also known as a web beacon) is a piece of code embedded in our Services that collects information about engagement on our Services. The use of a pixel tag allows us to record, for example, that a user has visited a particular web page or clicked on a particular advertisement. We may also include web beacons in e-mails to understand whether messages have been opened, acted on, or forwarded. Our uses of these Technologies fall into the following general categories: Operationally Necessary . This includes Technologies that allow you access to our Services, applications, and tools that are required to identify irregular website behavior, prevent fraudulent activity and improve security or that allow you to make use of our functionality. Performance-Related . We may use Technologies to assess the performance of our Services, including as part of our analytic practices to help us understand how individuals use our Services ( see Analytics below ). Functionality-Related . We may use Technologies that allow us to offer you enhanced functionality when accessing or using our Services. This may include identifying you when you sign into our Services or keeping track of your specified preferences, interests, or past items viewed. Analytics . We may use Technologies and other third-party tools to process analytics information on our Services. Some of our analytics partners include Google Analytics. For more information,please visit Google Analytics' Privacy Policy . To learn more about how to opt-out of Google Analytics' use of your information, please click here . Social Media Platforms . Our Services may contain social media buttons such as Twitter, Facebook, GitHub, Instagram, and Twitch (that might include widgets such as the "share this" button or other interactive mini programs). These features may collect your IP address, which page you are visiting on our Services, and may set a cookie to enable the feature to function properly. Your interactions with these platforms are governed by the privacy policy of the company providing it. See the "Your Privacy Choices and Rights" section below to understand your choices regarding these Technologies. C. Information Collected from Other Sources We may obtain information about you from other sources, including through third-party services and organizations. For example, if you access our Services through a third-party application, such as an app store, a third-party login service (e.g., through Twitter, Apple, or GitHub), or a social networking site, we may collect whatever information about you from that third-party application that you have made available via your privacy settings. 3. HOW WE USE YOUR INFORMATION We use your information for a variety of business purposes, including to provide our Services, for administrative purposes, and to market our products and Services, as described below.

Report Abuse Jaeil Woo Posted on Jan 11 Building a "Remembering" AI Trading Agent with Python, LangGraph, and Obsidian # ai # machinelearning # python # opensource Hello DEV community! I'm excited to share an open-source project I've been working on: TradingAgents-Dashboard . It's a Dockerized AI trading assistant that not only analyzes the market but remembers your insights forever using a local knowledge base (RAG). The Problem: "Stateless" AI Most AI trading bots today are "stateless". They run an analysis, give you a result, and then forget everything the moment you close the terminal. "Wait, didn't we decide last week that inflation correlates with this stock?" "Where is that news link I saw yesterday?" As a developer and trader, I wanted an agent that grows smarter over time, just like a human analyst. The Solution: AI + Obsidian (RAG) I built a dashboard wrapping the TradingAgents framework, adding a persistent memory layer using Obsidian . Github Repo: jiwoomap/TradingAgents-Dashboard How it works: Analyze: Agents (Bull, Bear, Risk Manager) debate market conditions using LangGraph. Persist: All insights and debates are auto-saved to your local Obsidian Vault as Markdown files. Recall (RAG): Before making a new decision, the agents search your vault (via ChromaDB) to retrieve past lessons and context. Tech Stack Framework: LangChain / LangGraph (Multi-Agent Orchestration) UI: Streamlit (Web Dashboard) Database: ChromaDB (Vector Store for RAG) Memory: Obsidian (Markdown-based Knowledge Base) Infrastructure: Docker & Docker Compose Key Features Interactive Debate UI: Watch the "Bull" and "Bear" agents fight it out in real-time. Fact Checker: Prevents hallucinations by validating news URLs (200 OK checks). Dockerized: Get started in 1 minute with docker-compose up . Data Sovereignty: Your financial data and strategies live on your disk , not in a cloud database. Try it out! I'd love to get your feedback. If you're interested in AI Agents or FinTech, give it a spin!

https://piccalil.li/javascript-for-everyone | JavaScript for Everyone - Piccalilli Switch to Dark Theme Take the course A Piccalilli premium course Truly understand how JavaScript works Future-proof your career with this in-depth course from Mat Marquis. You’ll walk away with the confidence that comes with understanding how JavaScript works, to a level that can otherwise take years to unlock. Watch the trailer Close Take your skillset way beyond syntax expertise Being a senior level JavaScript developer is not about memorising countless methods and properties, it’s about gaining a fundamental understanding of the way JavaScript “thinks”. Here’s the rub: there isn’t always time in a project to dig into the how and why — not when there’s work to do and tickets to close. Gaining that understanding through trial and error, copied-and-pasted snippets, or working with frameworks that make tasks quicker and easier by papering over the gritty details can take a person years. What I’m doing with this course is to teach you how the language works , how it really works, because that knowledge is what sets a truly senior developer apart. After you complete this course, your knowledge of the language will give you unrecognisable levels of confidence and transferable skills that you can apply, regardless of your organisation’s preference in framework. This course isn’t a catalogue of every method and property JavaScript has to offer; you won’t find any flash cards or vocab quizzes here. We’re going to focus on the syntaxes you’re most likely to encounter in your day-to-day work , the ones that make up more advanced features of the language, and most importantly, the ones that will help you gain a better understanding of JavaScript , the language, as it is played. My goal isn’t for you to walk away from this course knowing the whole of JavaScript — that’s impossible. My goal is to help you understand JavaScript : why it works the way it does, why sometimes things that feel like they should work don’t , and why things that feel like they shouldn’t work sometimes do . If you should find yourself hitting a wall, don’t stress: I’ll be here to help right alongside your peers in the JavaScript for Everyone Discord community. — Mat Take the course for just £249 £199.20 Let’s take your skillset way beyond syntax expertise If I wanted to learn something, I’d first check to see if Mat Marquis wrote about it. I know few people as skilled at breaking down complex ideas into human-sized chunks; I know even fewer folks who write with such easy, approachable wit. I’ve learned so much from Mat over my career, and I’m excited I’ll be learning something new from him real soon. I can’t wait to check out JavaScript for Everyone. Ethan Marcotte , Designer, writer and creator of responsive web design I’d read Mat’s writing purely for pleasure. I’ve read a lot of technical writing in my time. It’s a skill to deliver technical correctness with clarity and brevity. Even then, rarely do you end up with anything fun. Mat reads like a grizzled poet, with more curly brackets than em dashes, teaching you just what you need right when you need it. It’s perfect, and you’ll end up wanting more. Chris Coyier , Co-Founder, CodePen I have read every single word of this course and let me tell you, it is unbelievable . JavaScript is a complicated language to learn, especially for someone like me, who’s a designer by trade. Even with that context, I can feel how much better I am at writing JavaScript and how much more confident I am. I’m so thankful to Mat for that, especially. Andy Bell , Founder, Piccalilli Why take this course? Benefits Education from an industry expert Your instructor, Mat Marquis has over 20 years in the industry, and an eye-watering depth of experience. You may not realize it in the moment, but you’re already familiar with his output — from his pioneering responsive web design work with the Boston Globe, to his time on the jQuery Team, to Chairing The web standards group at the W3C that brought responsive image markup to the web platform. Mat is a two-time A Book Apart author, has written multiple courses for Google's web.dev learning platform, and has spoken at conferences like Smashing, Beyond Tellerand, and An Event Apart. In his own words, he “ keeps busy .” Skills that will always beat AI reliance You might think “it’s ok, I don't need to understand JavaScript too deeply because I can lean on AI” and sure, we understand why people feel like that. The problem with AI tools though is they make you a passive developer and when stuff does go wrong — which it always does — by having a deep knowledge of JavaScript from this course, you will be able to tackle those problems head-on and you’ll fully understand what has actually gone wrong , regardless of the framework and tools you use. And beyond that, if you do need or choose to use AI, this depth of knowledge will help you to elevate the output of the tools to match your standards, not the other way around. A long-term guide that you can trust The course is designed to be read, lesson-by-lesson, in order, at your own pace , but it’s much more than that. You’re going to stumble into issues while you work with JavaScript, so this course, in the long-term, will be a trusted resource you can pick up, again and again to help you out. All content updates are free forever as this content evolves to be as useful as possible for everyone. Accessible, highly approachable content This course is over 86,000 words. With his highly approachable and digestible writing style and inimitable wit , Mat manages to deliver this depth of content in a way that makes it highly accessible. This is the thing you see, it's all about how you teach. Anyone could write a dry, but detailed guide about how JavaScript works, but most people would just gloss over that. Mat gives you the details — oh boy, he does that — but he does so with a rhythm and flow that helps that knowledge to stick . There's no better way to learn than with a smile on your face. Our end-game is to give you the skills you need for long-term career progression Let’s get you paid By learning how and why JavaScript works on a fundamental level, you’ll be in a stronger position to weather the changes our industry is going through. Our industry is changing, constantly. The AI hype cycle poses an increasing risk to job security, and despite every promise otherwise the output from AI code generators is failing to live up to the hype . Deep knowledge and skills have never been more important. Understanding JavaScript deeply will mean you’ll be the one that’s called upon to oversee and course correct the AI-generated output . And when the AI bubble does pop, having a deep knowledge of how JavaScript works will put you in a strong position to command more compensation and better terms because you’ll be in the strongest position to fix the mess left behind by AI . Take the course for just £249 £199.20 Let’s take your skillset way beyond syntax expertise Mat’s domain experience, moral compass, and playful rhetoric make him one of my favourite tech writers working today. Whatever he chooses to publish, you can rest assured that reading will broaden your horizons and lighten your spirits. Mike Pennisi , Worker-owner and engineer at Bocoup Mat’s writing stands out in an industry that is full of unnecessary over-complication for complication’s sake. He takes technical concepts and breaks them down in a way that is direct, easy to understand, and oftentimes entertaining. JavaScript for Everyone is a gift for anyone looking to improve their understanding of the language that powers the web. Eric Bailey , Senior Accessibility Designer, GitHub A lot of folks in tech spend their careers building enormous (and enormously intimidating) walls of complexity. Mat’s made his career out of smashing those walls: breaking ’em down with clarity and concision and making sure everything he puts into the world is inclusive, approachable, and, frankly – fun Eric Portis , Developer Evangelist, Cloudinary This course goes deep Curriculum overview With over fifty lessons spanning twelve modules, and over 86,000 words, this course will teach you to understand JavaScript deeply . JavaScript is a complicated language to learn, and Mat’s unique, highly approachable writing style brings a rhythm and flow that really helps the knowledge to stick.

Report Abuse Mohammad-Idrees Posted on Jan 13 Thinking in First Principles: How to Question an Async Queue–Based Design # architecture # interview # learning # systemdesign Async queues are one of the most commonly suggested “solutions” in system design interviews. But many candidates jump straight to using queues without understanding: What problems they actually solve What new problems they introduce How to systematically discover those problems This post teaches a first-principles questioning process you can apply to any async queue design—without assuming prior knowledge. Why This Matters In interviews, interviewers are not evaluating whether you know Kafka, SQS, or RabbitMQ. They are evaluating whether you can: Reason about time Reason about failure Reason about order Reason about user experience Async queues change all four. What “First Principles” Means Here First principles means: We do not start with solutions We do not assume correctness We ask basic, unavoidable questions that every system must answer Async queues feel correct because they remove blocking—but correctness is not guaranteed by intuition. The Reference Mental Model (Abstract) We will reason about this abstract pattern , not a specific product: User → API → Storage → Queue → Worker → Storage Enter fullscreen mode Exit fullscreen mode No domain assumptions. This could be: Chat messages Emails Payments Notifications Image processing The questioning process stays the same. Step 1: The Root Question (Always Start Here) What is the system responsible for completing before it can respond? This is the most important question in system design. Why? Because it defines: Request boundaries Latency expectations Responsibility In an async queue design, the implicit answer is: “The request is complete once the work is enqueued.” This is different from synchronous designs, where the request completes after work finishes. So far, this seems good. Step 2: Introduce Time (What Happens Later?) Now ask: Which part of the work happens after the request is done? Answer: The worker processing This leads to an important realization: The system has split work across time Time separation is powerful—but it creates new questions. Step 3: Causality Question (Identity Across Time) Once work happens later, we must ask: How does the system know which output belongs to which input? This question always appears when time is decoupled. Typical answer: IDs in the job payload (request ID, entity ID) This introduces a new invariant: Each input must produce exactly one correct output Now we test whether the system can guarantee this. Step 4: Failure Question (The Queue Reality) Now ask the most important async-specific question: What happens if the worker crashes mid-processing? Realistic answers: The job is retried The work may run again The output may be produced twice This leads to a critical realization: Async queues are usually at-least-once , not exactly-once This is not a tooling issue. It is a fundamental property of distributed systems . Step 5: Duplication Question (Invariant Violation) Now ask: What happens if the same job is processed twice? Consequences: Duplicate outputs Duplicate side effects Conflicting state This violates the earlier invariant: “Exactly one output per input” At this point, we have discovered a correctness problem , not a performance problem. Step 6: Ordering Question (Time Without Synchrony) Now consider multiple inputs. Ask: What defines the order of processing? Important realization: Queue order ≠ business order Different workers process at different speeds Later inputs may finish first Now ask: Does correctness depend on order? If yes (and many systems do): Async queues alone are insufficient This problem emerges only when you question order explicitly. Step 7: Visibility Question (User Experience) Now switch perspectives. How does the user know the work is finished? Possible answers: Polling Guessing Timeouts Each answer reveals a problem: Polling wastes resources Guessing is unreliable Timeouts fail under load This violates a core system principle: Users should not wait blindly Case Study: A Simple Example (Problem-Agnostic) Imagine a system where users upload photos to be processed. Flow: User uploads photo API stores metadata Job is enqueued Worker processes photo Result is stored Now apply the questions: When does the upload request complete? → After enqueue What if the worker crashes? → Job retried What if it runs twice? → Two processed images What if two photos depend on order? → Order not guaranteed How does the user know processing is done? → Polling None of these issues are about images. They are about time, failure, identity, and visibility . What Async Queues Actually Trade Async queues solve one problem: They remove blocking from the request path But they introduce others: Solved Introduced Blocking Duplicate work Latency coupling Ordering ambiguity Resource exhaustion Completion uncertainty This is not bad. It just must be understood and handled . The One-Page Interview Checklist (Memorize This) For any async queue design , ask these five questions: What completes the request? What runs later? What happens if it runs twice? What defines order? How does the user observe completion? If you cannot answer all five clearly, the design is incomplete. Final Mental Model Async systems remove time coupling but destroy causality by default Your job as an engineer is not to “use queues” Your job is to restore correctness explicitly That is what interviewers are looking for.

Report Abuse Mohammad-Idrees Posted on Jan 13 Thinking in First Principles: How to Question an Async Queue–Based Design # architecture # interview # learning # systemdesign Async queues are one of the most commonly suggested “solutions” in system design interviews. But many candidates jump straight to using queues without understanding: What problems they actually solve What new problems they introduce How to systematically discover those problems This post teaches a first-principles questioning process you can apply to any async queue design—without assuming prior knowledge. Why This Matters In interviews, interviewers are not evaluating whether you know Kafka, SQS, or RabbitMQ. They are evaluating whether you can: Reason about time Reason about failure Reason about order Reason about user experience Async queues change all four. What “First Principles” Means Here First principles means: We do not start with solutions We do not assume correctness We ask basic, unavoidable questions that every system must answer Async queues feel correct because they remove blocking—but correctness is not guaranteed by intuition. The Reference Mental Model (Abstract) We will reason about this abstract pattern , not a specific product: User → API → Storage → Queue → Worker → Storage Enter fullscreen mode Exit fullscreen mode No domain assumptions. This could be: Chat messages Emails Payments Notifications Image processing The questioning process stays the same. Step 1: The Root Question (Always Start Here) What is the system responsible for completing before it can respond? This is the most important question in system design. Why? Because it defines: Request boundaries Latency expectations Responsibility In an async queue design, the implicit answer is: “The request is complete once the work is enqueued.” This is different from synchronous designs, where the request completes after work finishes. So far, this seems good. Step 2: Introduce Time (What Happens Later?) Now ask: Which part of the work happens after the request is done? Answer: The worker processing This leads to an important realization: The system has split work across time Time separation is powerful—but it creates new questions. Step 3: Causality Question (Identity Across Time) Once work happens later, we must ask: How does the system know which output belongs to which input? This question always appears when time is decoupled. Typical answer: IDs in the job payload (request ID, entity ID) This introduces a new invariant: Each input must produce exactly one correct output Now we test whether the system can guarantee this. Step 4: Failure Question (The Queue Reality) Now ask the most important async-specific question: What happens if the worker crashes mid-processing? Realistic answers: The job is retried The work may run again The output may be produced twice This leads to a critical realization: Async queues are usually at-least-once , not exactly-once This is not a tooling issue. It is a fundamental property of distributed systems . Step 5: Duplication Question (Invariant Violation) Now ask: What happens if the same job is processed twice? Consequences: Duplicate outputs Duplicate side effects Conflicting state This violates the earlier invariant: “Exactly one output per input” At this point, we have discovered a correctness problem , not a performance problem. Step 6: Ordering Question (Time Without Synchrony) Now consider multiple inputs. Ask: What defines the order of processing? Important realization: Queue order ≠ business order Different workers process at different speeds Later inputs may finish first Now ask: Does correctness depend on order? If yes (and many systems do): Async queues alone are insufficient This problem emerges only when you question order explicitly. Step 7: Visibility Question (User Experience) Now switch perspectives. How does the user know the work is finished? Possible answers: Polling Guessing Timeouts Each answer reveals a problem: Polling wastes resources Guessing is unreliable Timeouts fail under load This violates a core system principle: Users should not wait blindly Case Study: A Simple Example (Problem-Agnostic) Imagine a system where users upload photos to be processed. Flow: User uploads photo API stores metadata Job is enqueued Worker processes photo Result is stored Now apply the questions: When does the upload request complete? → After enqueue What if the worker crashes? → Job retried What if it runs twice? → Two processed images What if two photos depend on order? → Order not guaranteed How does the user know processing is done? → Polling None of these issues are about images. They are about time, failure, identity, and visibility . What Async Queues Actually Trade Async queues solve one problem: They remove blocking from the request path But they introduce others: Solved Introduced Blocking Duplicate work Latency coupling Ordering ambiguity Resource exhaustion Completion uncertainty This is not bad. It just must be understood and handled . The One-Page Interview Checklist (Memorize This) For any async queue design , ask these five questions: What completes the request? What runs later? What happens if it runs twice? What defines order? How does the user observe completion? If you cannot answer all five clearly, the design is incomplete. Final Mental Model Async systems remove time coupling but destroy causality by default Your job as an engineer is not to “use queues” Your job is to restore correctness explicitly That is what interviewers are looking for.

This year, we've focused on delivering critical security enhancements, rolling out powerful new features for organizations, improving the overall user experience for the millions of developers who rely on PyPI every day, and responding to a number of security incidents with transparency. Continue reading November 26, 2025 2 min read PyPI and Shai-Hulud: Staying Secure Amid Emerging Threats An attack on the npm ecosystem continues to evolve, exploiting compromised accounts to publish malicious packages. This campaign, dubbed Shai-Hulud , has targeted large volumes of packages in the JavaScript ecosystem, exfiltrating credentials to further propagate itself. PyPI has not been exploited , however some PyPI credentials were found exposed in compromised repositories. We've revoked these tokens as a precaution, there's no evidence they have been used maliciously. This post raises awareness about the attack and encourages proactive steps to secure your accounts, especially if you're using build platforms to publish packages to PyPI. Continue reading November 14, 2025 2 min read New Login Verification for TOTP-based Logins We've implemented a new security feature designed to protect PyPI users from phishing attacks: email verification for TOTP-based logins from new devices.

Recap: Trusted Publishing enables software build platforms to publish packages to PyPI on your behalf, eliminating the need to manage long-lived authentication tokens. After a one-time setup where you delegate publishing authority to your platform, it automatically obtains short-lived, scoped tokens for each build—no manual token management required. Read the Security Model for a deeper understanding of how Trusted Publishing works.

This is the same attack PyPI saw a few months ago and targeting many other open source repositories but with a different domain name. Judging from this, we believe this type of campaign will continue with new domains in the future. Continue reading September 16, 2025 3 min read Token Exfiltration Campaign via GitHub Actions Workflows Summary I recently responded to an attack campaign where malicious actors injected code into GitHub Actions workflows attempting to steal PyPI publishing tokens. PyPI was not compromised, and no PyPI packages were published by the attackers. Attackers targeted a wide variety of repositories, many of which had PyPI tokens stored as GitHub secrets, modifying their workflows to send those tokens to external servers. While the attackers successfully exfiltrated some tokens, they do not appear to have used them on PyPI. I've invalidated all affected tokens and notified the impacted project maintainers. If you're one of them, I have emailed you from security@pypi.org . Continue reading August 18, 2025 4 min read Preventing Domain Resurrection Attacks Summary PyPI now checks for expired domains to prevent domain resurrection attacks, a type of supply-chain attack where someone buys an expired domain and uses it to take over PyPI accounts through password resets. These changes improve PyPI's overall account security posture, making it harder for attackers to exploit expired domain names to gain unauthorized access to accounts.

This allows downstream consumers (like Python package installers and index mirrors) to retrieve project statuses programmatically and use them to inform users when a project is archived or quarantined. Summary PyPI has implemented project status markers as proposed and accepted in PEP 792 . As of today, PyPI supports three standard statuses: active (the default), archived , and quarantined . Downstream consumers can now retrieve these statuses via the standard index APIs and use them to inform users about the state of a project. See the project archival and project quarantine announcement posts for additional information on PyPI's implementation of those individual statuses.

This has been done in response to the discovery that the popular installer uv has a different extraction behavior to many Python-based installers that use the ZIP parser implementation provided by the zipfile standard library module. Summary ZIP archives constructed to exploit ZIP confusion attacks are now rejected by PyPI. There is no evidence that this vulnerability has been exploited using PyPI. PyPI is deprecating wheel distributions with incorrect RECORD files. Please see this blog post and CVE-2025-54368 for more information on uv's patch.

Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content. Helpful Resources Below you'll find various resources we recommend for better understanding DEV's writing policies and tools. DEV Editor guide A quick guide that provides you with technical tips for using the DEV Editor and our brand of Markdown. You can also find it by clicking the "?" page in the editor . Markdown Cheatsheet A handy cheatsheet for commonly-used Markdown formatting syntax. Best Practices for Writing on DEV A helpful series that offers both technical tips and general guidance for making the best-fit article for DEV. 🙌 Guidelines for Avoiding Plagiarism on DEV This resource offers guidance for how to avoid plagiarism. We take a strong stance against plagiarism on DEV; please don't hesitate to report any plagiarism to us. Guidelines for AI-assisted Articles on DEV These guidelines detail our requirements for properly labelling AI-assisted content on DEV. Please don't hesitate to report any content that is written with AI-assistance if it isn't following these guidelines. Common Questions Q: How do I set a canonical URL on my post? In the post editor, click the hexagon icon in the bottom left-hand corner beside "save draft" and you'll see an input box to designate a Canonical URL. Note: if you are using the Basic Markdown editor you must add a line for it inside the triple dashes (aka Front Matter), like so: --- title: published: false tags: canonical_url: <https://mycoolsite.com/my-post> --- Q: How do I set a cover image for my post? If using the Rich + Markdown editor, then click the "Add a cover image" button above the title of the post. If using the Basic Markdown editor, include cover_image: [url] in the front matter of your post. Note: you may change your editor type from your settings . Q: Do I own the articles that I publish? Yes, you own the rights to the content you create and post on dev.to and you have the full authority to post, edit, and remove your content as you see fit. Q: Can I cross-post something I've already written on my own blog or Medium? Absolutely, as long as you have the rights you need to do so! And if it's of high quality, we'll feature it. Q: Can I use profanity in my posts? We don't disallow profanity in general, but we do have an internal policy of not promoting posts that have profanity in the title, so you might want to keep that in mind. If your profanity is targeted at individuals or hateful, then it would cross the lines of what's acceptable via our Code of Conduct and we may take necessary action to remove you content. Q: Why has my post been removed? Your post is subject to removal at the discretion of the moderators if they believe it does not meet the requirements of our Code of Conduct .

Report Abuse Jaeil Woo Posted on Jan 11 Building a "Remembering" AI Trading Agent with Python, LangGraph, and Obsidian # ai # machinelearning # python # opensource Hello DEV community! I'm excited to share an open-source project I've been working on: TradingAgents-Dashboard . It's a Dockerized AI trading assistant that not only analyzes the market but remembers your insights forever using a local knowledge base (RAG). The Problem: "Stateless" AI Most AI trading bots today are "stateless". They run an analysis, give you a result, and then forget everything the moment you close the terminal. "Wait, didn't we decide last week that inflation correlates with this stock?" "Where is that news link I saw yesterday?" As a developer and trader, I wanted an agent that grows smarter over time, just like a human analyst. The Solution: AI + Obsidian (RAG) I built a dashboard wrapping the TradingAgents framework, adding a persistent memory layer using Obsidian . Github Repo: jiwoomap/TradingAgents-Dashboard How it works: Analyze: Agents (Bull, Bear, Risk Manager) debate market conditions using LangGraph. Persist: All insights and debates are auto-saved to your local Obsidian Vault as Markdown files. Recall (RAG): Before making a new decision, the agents search your vault (via ChromaDB) to retrieve past lessons and context. Tech Stack Framework: LangChain / LangGraph (Multi-Agent Orchestration) UI: Streamlit (Web Dashboard) Database: ChromaDB (Vector Store for RAG) Memory: Obsidian (Markdown-based Knowledge Base) Infrastructure: Docker & Docker Compose Key Features Interactive Debate UI: Watch the "Bull" and "Bear" agents fight it out in real-time. Fact Checker: Prevents hallucinations by validating news URLs (200 OK checks). Dockerized: Get started in 1 minute with docker-compose up . Data Sovereignty: Your financial data and strategies live on your disk , not in a cloud database. Try it out! I'd love to get your feedback.

Report Abuse BeardDemon Posted on Jan 10 J'ai galéré pendant 3 semaines pour monter un cluster Kubernetes (et voilà ce que j'ai appris) # kubernetes # devops # learning Le contexte Bon, soyons honnêtes. Au début, j'avais un gros bordel de scripts bash éparpillés partout. Genre 5-6 fichiers avec des noms comme install-docker.sh , setup-k8s-FINAL-v3.sh (oui, le v3...). À chaque fois que je devais recréer mon infra, c'était 45 minutes de galère + 10 minutes à me demander pourquoi ça marchait pas. J'avais besoin de quelque chose de plus propre pour mon projet SAE e-commerce. Ce que je voulais vraiment Pas un truc de démo avec minikube. Non. Je voulais: 3 VMs qui tournent vraiment (1 master + 2 workers) Tout automatisé - je tape une commande et ça se déploie ArgoCD pour faire du GitOps (parce que push to deploy c'est quand même cool) Des logs centralisés (Loki + Grafana) Et surtout : pouvoir tout péter et tout recréer en 10 minutes L'architecture (spoiler: ça marche maintenant) ┌─────────────────────────────────────────┐ │ Mon PC (Debian) │ │ ┌──────────┐ ┌──────────┐ ┌─────────┐ │ │ Master │ │ Worker 1 │ │ Worker 2│ │ │ .56.10 │ │ .56.11 │ │ .56.12 │ │ └──────────┘ └──────────┘ └─────────┘ └─────────────────────────────────────────┘ Enter fullscreen mode Exit fullscreen mode Chaque VM a 4Go de RAM et 4 CPUs. Oui, ça bouffe des ressources. Non, ça passe pas sur un laptop pourri. Comment c'est organisé J'ai tout mis dans un repo bien rangé (pour une fois): ansible-provisioning/ ├── Vagrantfile # Les 3 VMs ├── playbook.yml # Le chef d'orchestre ├── manifests/ # Mes applis K8s │ ├── apiclients/ │ ├── apicatalogue/ │ ├── databases/ │ └── ... (toutes mes APIs) └── roles/ # Les briques Ansible ├── docker/ ├── kubernetes/ ├── k8s-master/ └── argocd/ Enter fullscreen mode Exit fullscreen mode Chaque rôle fait UN truc. C'est ça qui a changé ma vie. Shell scripts → Ansible : pourquoi j'ai migré Avant (la galère) J'avais un script prepare-system.sh qui ressemblait à ça: #!/bin/bash swapoff -a sed -i '/swap/d' /etc/fstab modprobe br_netfilter # ... 50 lignes de commandes # Aucune gestion d'erreur # Si ça plante au milieu, bonne chance Enter fullscreen mode Exit fullscreen mode Le pire ? Si je relançais le script après un fail, tout pétait. Genre le sed essayait de supprimer une ligne qui existait plus. Classique. Après (je respire enfin) Maintenant j'ai un rôle Ansible system-prepare : - name : Virer le swap shell : swapoff -a ignore_errors : yes - name : Enlever le swap du fstab lineinfile : path : /etc/fstab regexp : ' .*swap.*' state : absent - name : Charger br_netfilter modprobe : name : br_netfilter state : present Enter fullscreen mode Exit fullscreen mode La différence ? Je peux relancer 10 fois, ça fait pas de conneries C'est lisible par un humain Si ça plante, je sais exactement où Le Vagrantfile (ou comment lancer 3 VMs d'un coup) Vagrant . configure ( "2" ) do | config | config . vm . box = "debian/bullseye64" # Config libvirt (KVM/QEMU) config . vm . provider "libvirt" do | libvirt | libvirt . memory = 4096 libvirt . cpus = 4 libvirt . management_network_address = "192.168.56.0/24" end # NFS pour partager les manifests config . vm . synced_folder "." , "/vagrant" , type: "nfs" , nfs_version: 4 # Le master config . vm . define "vm-master" do | vm | vm . vm . network "private_network" , ip: "192.168.56.10" vm . vm . hostname = "master" end # Les 2 workers ( 1 .. 2 ). each do | i | config . vm . define "vm-slave- #{ i } " do | vm | vm . vm . network "private_network" , ip: "192.168.56.1 #{ i } " vm . vm . hostname = "slave- #{ i } " end end # Ansible se lance automatiquement config . vm . provision "ansible" do | ansible | ansible . playbook = "playbook.yml" ansible . groups = { "master" => [ "vm-master" ], "workers" => [ "vm-slave-1" , "vm-slave-2" ] } end end Enter fullscreen mode Exit fullscreen mode Un vagrant up et boom, tout se monte tout seul. Le playbook : l'ordre c'est important --- # 1. Tous les nœuds en même temps - name : Setup de base hosts : k8s_cluster roles : - system-prepare # Swap off, modules kernel - docker # Docker + containerd - kubernetes # kubelet, kubeadm, kubectl # 2. Le master d'abord - name : Init master hosts : master roles : - k8s-master # kubeadm init + Flannel # 3. Les workers ensuite, un par un - name : Join workers hosts : workers serial : 1 # IMPORTANT: un à la fois roles : - k8s-worker # 4. Les trucs bonus sur le master - name : Dashboard + ArgoCD + Monitoring hosts : master roles : - k8s-dashboard - argocd - logging - metrics-server Enter fullscreen mode Exit fullscreen mode Le serial: 1 c'est crucial. J'avais essayé sans, les deux workers essayaient de join en même temps et ça partait en cacahuète. Les rôles en détail Rôle: k8s-master (le chef d'orchestre) C'est lui qui initialise le cluster. Voici les parties importantes: - name : Init cluster k8s command : kubeadm init --apiserver-advertise-address=192.168.56.10 --pod-network-cidr=10.244.0.0/16 when : not k8s_initialise.stat.exists - name : Copier config kubectl copy : src : /etc/kubernetes/admin.conf dest : /home/vagrant/.kube/config owner : vagrant group : vagrant - name : Installer Flannel (réseau pod) shell : | kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml environment : KUBECONFIG : /home/vagrant/.kube/config - name : Générer commande join pour les workers copy : content : " kubeadm join 192.168.56.10:6443 --token {{ k8s_token.stdout }} --discovery-token-ca-cert-hash sha256:{{ k8s_ca_hash.stdout }}" dest : /vagrant/join.sh mode : ' 0755' - name : Créer fichier .master-ready copy : content : " Master initialized" dest : /vagrant/.master-ready Enter fullscreen mode Exit fullscreen mode Le fichier .master-ready c'est un flag pour dire aux workers "go, vous pouvez join maintenant". Rôle: k8s-worker (le suiveur patient) - name : Attendre que le fichier .master-ready existe wait_for : path : /vagrant/.master-ready timeout : 600 - name : Joindre le cluster shell : bash /vagrant/join.sh args : creates : /etc/kubernetes/kubelet.conf register : join_result failed_when : - join_result.rc != 0 - " 'already exists in the cluster' not in join_result.stderr" - name : Attendre que le node soit Ready shell : | for i in {1..60}; do STATUS=$(kubectl get node $(hostname) -o jsonpath='{.status.conditions[?(@.type=="Ready")].status}') if [ "$STATUS" = "True" ]; then exit 0 fi sleep 5 done exit 1 Enter fullscreen mode Exit fullscreen mode Le worker attend gentiment que le master soit prêt avant de faire quoi que ce soit. Les galères que j'ai rencontrées Galère #1: NFS qui marche pas Au début, le partage NFS entre l'hôte et les VMs plantait. Symptôme: mount.nfs: Connection timed out Enter fullscreen mode Exit fullscreen mode Solution: # Sur l'hôte sudo apt install nfs-kernel-server sudo systemctl start nfs-server sudo ufw allow from 192.168.56.0/24 Enter fullscreen mode Exit fullscreen mode Le firewall bloquait les connexions NFS. Classique. Galère #2: Kubeadm qui timeout Le kubeadm init prenait 10 minutes et finissait par timeout. Cause: Pas assez de RAM sur les VMs (j'avais mis 2Go). Solution: Passer à 4Go par VM. Ça bouffe mais c'est nécessaire. Galère #3: Les workers qui join pas Les workers restaient en NotReady même après le join. Cause: Flannel (le CNI) était pas encore installé sur le master. Solution: Attendre que Flannel soit complètement déployé avant de faire join les workers: - name : Attendre Flannel command : kubectl wait --for=condition=ready pod -l app=flannel -n kube-flannel --timeout=300s environment : KUBECONFIG : /etc/kubernetes/admin.conf Enter fullscreen mode Exit fullscreen mode Galère #4: Ansible qui relance tout à chaque fois Au début, chaque vagrant provision refaisait TOUT depuis zéro. Solution: Ajouter des conditions when partout: - name : Init cluster k8s command : kubeadm init ... when : not k8s_initialise.stat.exists # ← Ça sauve des vies Enter fullscreen mode Exit fullscreen mode L'idempotence c'est vraiment la base avec Ansible. Les commandes utiles au quotidien # Lancer tout cd ansible-provisioning && vagrant up # Vérifier l'état du cluster vagrant ssh vm-master -c 'kubectl get nodes' # Voir les pods vagrant ssh vm-master -c 'kubectl get pods -A' # Refaire le provisioning (sans détruire les VMs) vagrant provision # Tout péter et recommencer vagrant destroy -f && vagrant up # SSH sur le master vagrant ssh vm-master # Logs d'un pod vagrant ssh vm-master -c 'kubectl logs -n apps apicatalogue-xyz' Enter fullscreen mode Exit fullscreen mode ArgoCD et les applications Une fois le cluster monté, ArgoCD déploie automatiquement mes apps. Voici comment je déclare l'API Catalogue: apiVersion : argoproj.io/v1alpha1 kind : Application metadata : name : catalogue-manager-application namespace : argocd spec : destination : namespace : apps server : https://kubernetes.default.svc source : path : ansible-provisioning/manifests/apicatalogue repoURL : https://github.com/uha-sae53/Vagrant.git targetRevision : main project : default syncPolicy : automated : prune : true selfHeal : true Enter fullscreen mode Exit fullscreen mode ArgoCD surveille mon repo GitHub. Dès que je change un manifest, ça se déploie automatiquement. Metrics Server et HPA J'ai aussi ajouté le Metrics Server pour l'auto-scaling: - name : Installer Metrics Server shell : | kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml environment : KUBECONFIG : /etc/kubernetes/admin.conf - name : Patcher pour ignorer TLS (dev seulement) shell : | kubectl patch deployment metrics-server -n kube-system --type='json' \ -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--kubelet-insecure-tls"}]' Enter fullscreen mode Exit fullscreen mode Avec ça, mes pods peuvent scaler automatiquement en fonction de la charge CPU/RAM. Le résultat final Après tout ça, voici ce que je peux faire: # Démarrer tout de zéro vagrant up # ⏱️ 8 minutes plus tard... # Vérifier que tout tourne vagrant ssh vm-master -c 'kubectl get pods -A' # Résultat: # NAMESPACE NAME READY STATUS # apps apicatalogue-xyz 1/1 Running # apps apiclients-abc 1/1 Running # apps apicommandes-def 1/1 Running # apps api-panier-ghi 1/1 Running # apps frontend-jkl 1/1 Running # argocd argocd-server-xxx 1/1 Running # logging grafana-yyy 1/1 Running # logging loki-0 1/1 Running # kube-system metrics-server-zzz 1/1 Running Enter fullscreen mode Exit fullscreen mode Tout fonctionne, tout est automatisé. Conclusion Ce que j'ai appris: Ansible > scripts shell (vraiment, vraiment) L'idempotence c'est pas un luxe Tester chaque rôle séparément avant de tout brancher Les workers doivent attendre le master (le serial: 1 sauve des vies) 4Go de RAM minimum par VM pour K8s Le code complet est sur GitHub: https://github.com/uha-sae53/Vagrant Des questions ? Ping moi sur Twitter ou ouvre une issue sur le repo. Et si vous galérez avec Kubernetes, vous êtes pas seuls. J'ai passé 3 semaines là-dessus, c'est normal que ce soit compliqué au début.

(optional) If you're using Highlight on the frontend for your application, make sure you've initialized it correctly and followed the fullstack mapping guide . 2 Install the Highlight Ruby SDK. Add Highlight to your Gemfile and install with Bundler. gem "highlight_io" bundle install 3 Initialize the Highlight Ruby SDK. Highlight.init initializes the SDK. Setting your project ID also lets Highlight record errors for background tasks and processes that aren't associated with a frontend session. require "highlight" Highlight.init("<YOUR_PROJECT_ID>", environment: "production") do |c| c.service_name = "my-app" c.service_version = "1.0.0" end 4 Verify your errors are being recorded. Now that you've set up the Middleware, verify that the backend error handling works by consuming an error from traced code. 5 Record custom errors. (optional) If you want to explicitly send an error to Highlight, you can use the error method within traced code. Highlight.exception(e) 6 Set up and call the Highlight Logger. Highlight::Logger can be used in place of your existing logger, and will record and send logs to Highlight. require "highlight" Highlight.init("<YOUR_PROJECT_ID>", environment: "production") do |c| c.service_name = "my-ruby-app" c.service_version = "git-sha" end logger = Highlight::Logger.new(STDOUT) logger.info('hello, world!') logger.error('oh no!') 7 Verify your backend logs are being recorded. Visit the highlight logs portal and check that backend logs are coming in. 8 Add Highlight tracing. start_span will automatically record raised exceptions and send them to Highlight. require "highlight" Highlight.start_span('my-span') do span.add_attribute({ key: "value" }) # your code here end 9 Verify your backend traces are being recorded. Visit the highlight traces portal and check that backend traces are coming in. Highlight Integration in Ruby Using highlight.io with Ruby on Rails [object Object] | 2026-01-13T08:49:01 |

Help > Writing, Editing and Scheduling Writing, Editing and Scheduling In this article The Editor Drafting and publishing a post: Scheduling a post: Creating a Series Cross-posting Content Helpful Resources DEV Editor guide Markdown Cheatsheet Best Practices for Writing on DEV Guidelines for Avoiding Plagiarism on DEV Guidelines for AI-assisted Articles on DEV Common Questions Q: How do I set a canonical URL on my post? Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content. Helpful Resources Below you'll find various resources we recommend for better understanding DEV's writing policies and tools. DEV Editor guide A quick guide that provides you with technical tips for using the DEV Editor and our brand of Markdown. You can also find it by clicking the "?" page in the editor . Markdown Cheatsheet A handy cheatsheet for commonly-used Markdown formatting syntax. Best Practices for Writing on DEV A helpful series that offers both technical tips and general guidance for making the best-fit article for DEV. 🙌 Guidelines for Avoiding Plagiarism on DEV This resource offers guidance for how to avoid plagiarism. We take a strong stance against plagiarism on DEV; please don't hesitate to report any plagiarism to us. Guidelines for AI-assisted Articles on DEV These guidelines detail our requirements for properly labelling AI-assisted content on DEV. Please don't hesitate to report any content that is written with AI-assistance if it isn't following these guidelines. Common Questions Q: How do I set a canonical URL on my post? In the post editor, click the hexagon icon in the bottom left-hand corner beside "save draft" and you'll see an input box to designate a Canonical URL. Note: if you are using the Basic Markdown editor you must add a line for it inside the triple dashes (aka Front Matter), like so: --- title: published: false tags: canonical_url: <https://mycoolsite.com/my-post> --- Q: How do I set a cover image for my post? If using the Rich + Markdown editor, then click the "Add a cover image" button above the title of the post. If using the Basic Markdown editor, include cover_image: [url] in the front matter of your post. Note: you may change your editor type from your settings . Q: Do I own the articles that I publish? Yes, you own the rights to the content you create and post on dev.to and you have the full authority to post, edit, and remove your content as you see fit. Q: Can I cross-post something I've already written on my own blog or Medium? Absolutely, as long as you have the rights you need to do so! And if it's of high quality, we'll feature it. Q: Can I use profanity in my posts? We don't disallow profanity in general, but we do have an internal policy of not promoting posts that have profanity in the title, so you might want to keep that in mind. If your profanity is targeted at individuals or hateful, then it would cross the lines of what's acceptable via our Code of Conduct and we may take necessary action to remove you content. Q: Why has my post been removed? Your post is subject to removal at the discretion of the moderators if they believe it does not meet the requirements of our Code of Conduct . If you think we may have made a mistake, please email us at support@dev.to . Q: Will you put ads on my posts' pages? It's possible. We do allow organizations to purchase advertisements with DEV. However, if you would prefer that no ads be placed next to your posts, just navigate to Settings > Customization , scroll down to sponsors, and uncheck the box beside "Permit Nearby External Sponsors (When publishing)" Of course, we'd appreciate it if you keep those boxes checked as this is important to our business. But, we respect your decision and appreciate you sharing posts with us! 💎 DEV Diamond Sponsors Thank you to our Diamond Sponsors for supporting the DEV Community Google AI is the official AI Model and Platform Partner of DEV Neon is the official database partner of DEV Algolia is the official search partner of DEV DEV Community — A space to discuss and keep up software development and manage your software career Home DEV++ Podcasts Videos DEV Education Tracks DEV Challenges DEV Help Advertise on DEV DEV Showcase About Contact Free Postgres Database Software comparisons Forem Shop Code of Conduct Privacy Policy Terms of Use Built on Forem — the open source software that powers DEV and other inclusive communities.

Q: Can I cross-post something I've already written on my own blog or Medium? Absolutely, as long as you have the rights you need to do so! And if it's of high quality, we'll feature it. Q: Can I use profanity in my posts? We don't disallow profanity in general, but we do have an internal policy of not promoting posts that have profanity in the title, so you might want to keep that in mind. If your profanity is targeted at individuals or hateful, then it would cross the lines of what's acceptable via our Code of Conduct and we may take necessary action to remove you content. Q: Why has my post been removed? Your post is subject to removal at the discretion of the moderators if they believe it does not meet the requirements of our Code of Conduct . If you think we may have made a mistake, please email us at support@dev.to . Q: Will you put ads on my posts' pages? It's possible. We do allow organizations to purchase advertisements with DEV. However, if you would prefer that no ads be placed next to your posts, just navigate to Settings > Customization , scroll down to sponsors, and uncheck the box beside "Permit Nearby External Sponsors (When publishing)" Of course, we'd appreciate it if you keep those boxes checked as this is important to our business.

Report Abuse BeardDemon Posted on Jan 10 J'ai galéré pendant 3 semaines pour monter un cluster Kubernetes (et voilà ce que j'ai appris) # kubernetes # devops # learning Le contexte Bon, soyons honnêtes. Au début, j'avais un gros bordel de scripts bash éparpillés partout. Genre 5-6 fichiers avec des noms comme install-docker.sh , setup-k8s-FINAL-v3.sh (oui, le v3...). À chaque fois que je devais recréer mon infra, c'était 45 minutes de galère + 10 minutes à me demander pourquoi ça marchait pas. J'avais besoin de quelque chose de plus propre pour mon projet SAE e-commerce. Ce que je voulais vraiment Pas un truc de démo avec minikube. Non. Je voulais: 3 VMs qui tournent vraiment (1 master + 2 workers) Tout automatisé - je tape une commande et ça se déploie ArgoCD pour faire du GitOps (parce que push to deploy c'est quand même cool) Des logs centralisés (Loki + Grafana) Et surtout : pouvoir tout péter et tout recréer en 10 minutes L'architecture (spoiler: ça marche maintenant) ┌─────────────────────────────────────────┐ │ Mon PC (Debian) │ │ ┌──────────┐ ┌──────────┐ ┌─────────┐ │ │ Master │ │ Worker 1 │ │ Worker 2│ │ │ .56.10 │ │ .56.11 │ │ .56.12 │ │ └──────────┘ └──────────┘ └─────────┘ └─────────────────────────────────────────┘ Enter fullscreen mode Exit fullscreen mode Chaque VM a 4Go de RAM et 4 CPUs. Oui, ça bouffe des ressources. Non, ça passe pas sur un laptop pourri. Comment c'est organisé J'ai tout mis dans un repo bien rangé (pour une fois): ansible-provisioning/ ├── Vagrantfile # Les 3 VMs ├── playbook.yml # Le chef d'orchestre ├── manifests/ # Mes applis K8s │ ├── apiclients/ │ ├── apicatalogue/ │ ├── databases/ │ └── ... (toutes mes APIs) └── roles/ # Les briques Ansible ├── docker/ ├── kubernetes/ ├── k8s-master/ └── argocd/ Enter fullscreen mode Exit fullscreen mode Chaque rôle fait UN truc. C'est ça qui a changé ma vie. Shell scripts → Ansible : pourquoi j'ai migré Avant (la galère) J'avais un script prepare-system.sh qui ressemblait à ça: #!/bin/bash swapoff -a sed -i '/swap/d' /etc/fstab modprobe br_netfilter # ... 50 lignes de commandes # Aucune gestion d'erreur # Si ça plante au milieu, bonne chance Enter fullscreen mode Exit fullscreen mode Le pire ? Si je relançais le script après un fail, tout pétait. Genre le sed essayait de supprimer une ligne qui existait plus. Classique. Après (je respire enfin) Maintenant j'ai un rôle Ansible system-prepare : - name : Virer le swap shell : swapoff -a ignore_errors : yes - name : Enlever le swap du fstab lineinfile : path : /etc/fstab regexp : ' .*swap.*' state : absent - name : Charger br_netfilter modprobe : name : br_netfilter state : present Enter fullscreen mode Exit fullscreen mode La différence ? Je peux relancer 10 fois, ça fait pas de conneries C'est lisible par un humain Si ça plante, je sais exactement où Le Vagrantfile (ou comment lancer 3 VMs d'un coup) Vagrant . configure ( "2" ) do | config | config . vm . box = "debian/bullseye64" # Config libvirt (KVM/QEMU) config . vm . provider "libvirt" do | libvirt | libvirt . memory = 4096 libvirt . cpus = 4 libvirt . management_network_address = "192.168.56.0/24" end # NFS pour partager les manifests config . vm . synced_folder "." , "/vagrant" , type: "nfs" , nfs_version: 4 # Le master config . vm . define "vm-master" do | vm | vm . vm . network "private_network" , ip: "192.168.56.10" vm . vm . hostname = "master" end # Les 2 workers ( 1 .. 2 ). each do | i | config . vm . define "vm-slave- #{ i } " do | vm | vm . vm . network "private_network" , ip: "192.168.56.1 #{ i } " vm . vm . hostname = "slave- #{ i } " end end # Ansible se lance automatiquement config . vm . provision "ansible" do | ansible | ansible . playbook = "playbook.yml" ansible . groups = { "master" => [ "vm-master" ], "workers" => [ "vm-slave-1" , "vm-slave-2" ] } end end Enter fullscreen mode Exit fullscreen mode Un vagrant up et boom, tout se monte tout seul. Le playbook : l'ordre c'est important --- # 1. Tous les nœuds en même temps - name : Setup de base hosts : k8s_cluster roles : - system-prepare # Swap off, modules kernel - docker # Docker + containerd - kubernetes # kubelet, kubeadm, kubectl # 2. Le master d'abord - name : Init master hosts : master roles : - k8s-master # kubeadm init + Flannel # 3. Les workers ensuite, un par un - name : Join workers hosts : workers serial : 1 # IMPORTANT: un à la fois roles : - k8s-worker # 4. Les trucs bonus sur le master - name : Dashboard + ArgoCD + Monitoring hosts : master roles : - k8s-dashboard - argocd - logging - metrics-server Enter fullscreen mode Exit fullscreen mode Le serial: 1 c'est crucial. J'avais essayé sans, les deux workers essayaient de join en même temps et ça partait en cacahuète. Les rôles en détail Rôle: k8s-master (le chef d'orchestre) C'est lui qui initialise le cluster. Voici les parties importantes: - name : Init cluster k8s command : kubeadm init --apiserver-advertise-address=192.168.56.10 --pod-network-cidr=10.244.0.0/16 when : not k8s_initialise.stat.exists - name : Copier config kubectl copy : src : /etc/kubernetes/admin.conf dest : /home/vagrant/.kube/config owner : vagrant group : vagrant - name : Installer Flannel (réseau pod) shell : | kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml environment : KUBECONFIG : /home/vagrant/.kube/config - name : Générer commande join pour les workers copy : content : " kubeadm join 192.168.56.10:6443 --token {{ k8s_token.stdout }} --discovery-token-ca-cert-hash sha256:{{ k8s_ca_hash.stdout }}" dest : /vagrant/join.sh mode : ' 0755' - name : Créer fichier .master-ready copy : content : " Master initialized" dest : /vagrant/.master-ready Enter fullscreen mode Exit fullscreen mode Le fichier .master-ready c'est un flag pour dire aux workers "go, vous pouvez join maintenant". Rôle: k8s-worker (le suiveur patient) - name : Attendre que le fichier .master-ready existe wait_for : path : /vagrant/.master-ready timeout : 600 - name : Joindre le cluster shell : bash /vagrant/join.sh args : creates : /etc/kubernetes/kubelet.conf register : join_result failed_when : - join_result.rc != 0 - " 'already exists in the cluster' not in join_result.stderr" - name : Attendre que le node soit Ready shell : | for i in {1..60}; do STATUS=$(kubectl get node $(hostname) -o jsonpath='{.status.conditions[?(@.type=="Ready")].status}') if [ "$STATUS" = "True" ]; then exit 0 fi sleep 5 done exit 1 Enter fullscreen mode Exit fullscreen mode Le worker attend gentiment que le master soit prêt avant de faire quoi que ce soit. Les galères que j'ai rencontrées Galère #1: NFS qui marche pas Au début, le partage NFS entre l'hôte et les VMs plantait. Symptôme: mount.nfs: Connection timed out Enter fullscreen mode Exit fullscreen mode Solution: # Sur l'hôte sudo apt install nfs-kernel-server sudo systemctl start nfs-server sudo ufw allow from 192.168.56.0/24 Enter fullscreen mode Exit fullscreen mode Le firewall bloquait les connexions NFS. Classique. Galère #2: Kubeadm qui timeout Le kubeadm init prenait 10 minutes et finissait par timeout. Cause: Pas assez de RAM sur les VMs (j'avais mis 2Go). Solution: Passer à 4Go par VM. Ça bouffe mais c'est nécessaire. Galère #3: Les workers qui join pas Les workers restaient en NotReady même après le join. Cause: Flannel (le CNI) était pas encore installé sur le master. Solution: Attendre que Flannel soit complètement déployé avant de faire join les workers: - name : Attendre Flannel command : kubectl wait --for=condition=ready pod -l app=flannel -n kube-flannel --timeout=300s environment : KUBECONFIG : /etc/kubernetes/admin.conf Enter fullscreen mode Exit fullscreen mode Galère #4: Ansible qui relance tout à chaque fois Au début, chaque vagrant provision refaisait TOUT depuis zéro. Solution: Ajouter des conditions when partout: - name : Init cluster k8s command : kubeadm init ... when : not k8s_initialise.stat.exists # ← Ça sauve des vies Enter fullscreen mode Exit fullscreen mode L'idempotence c'est vraiment la base avec Ansible. Les commandes utiles au quotidien # Lancer tout cd ansible-provisioning && vagrant up # Vérifier l'état du cluster vagrant ssh vm-master -c 'kubectl get nodes' # Voir les pods vagrant ssh vm-master -c 'kubectl get pods -A' # Refaire le provisioning (sans détruire les VMs) vagrant provision # Tout péter et recommencer vagrant destroy -f && vagrant up # SSH sur le master vagrant ssh vm-master # Logs d'un pod vagrant ssh vm-master -c 'kubectl logs -n apps apicatalogue-xyz' Enter fullscreen mode Exit fullscreen mode ArgoCD et les applications Une fois le cluster monté, ArgoCD déploie automatiquement mes apps. Voici comment je déclare l'API Catalogue: apiVersion : argoproj.io/v1alpha1 kind : Application metadata : name : catalogue-manager-application namespace : argocd spec : destination : namespace : apps server : https://kubernetes.default.svc source : path : ansible-provisioning/manifests/apicatalogue repoURL : https://github.com/uha-sae53/Vagrant.git targetRevision : main project : default syncPolicy : automated : prune : true selfHeal : true Enter fullscreen mode Exit fullscreen mode ArgoCD surveille mon repo GitHub. Dès que je change un manifest, ça se déploie automatiquement. Metrics Server et HPA J'ai aussi ajouté le Metrics Server pour l'auto-scaling: - name : Installer Metrics Server shell : | kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml environment : KUBECONFIG : /etc/kubernetes/admin.conf - name : Patcher pour ignorer TLS (dev seulement) shell : | kubectl patch deployment metrics-server -n kube-system --type='json' \ -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--kubelet-insecure-tls"}]' Enter fullscreen mode Exit fullscreen mode Avec ça, mes pods peuvent scaler automatiquement en fonction de la charge CPU/RAM. Le résultat final Après tout ça, voici ce que je peux faire: # Démarrer tout de zéro vagrant up # ⏱️ 8 minutes plus tard... # Vérifier que tout tourne vagrant ssh vm-master -c 'kubectl get pods -A' # Résultat: # NAMESPACE NAME READY STATUS # apps apicatalogue-xyz 1/1 Running # apps apiclients-abc 1/1 Running # apps apicommandes-def 1/1 Running # apps api-panier-ghi 1/1 Running # apps frontend-jkl 1/1 Running # argocd argocd-server-xxx 1/1 Running # logging grafana-yyy 1/1 Running # logging loki-0 1/1 Running # kube-system metrics-server-zzz 1/1 Running Enter fullscreen mode Exit fullscreen mode Tout fonctionne, tout est automatisé. Conclusion Ce que j'ai appris: Ansible > scripts shell (vraiment, vraiment) L'idempotence c'est pas un luxe Tester chaque rôle séparément avant de tout brancher Les workers doivent attendre le master (le serial: 1 sauve des vies) 4Go de RAM minimum par VM pour K8s Le code complet est sur GitHub: https://github.com/uha-sae53/Vagrant Des questions ? Ping moi sur Twitter ou ouvre une issue sur le repo. Et si vous galérez avec Kubernetes, vous êtes pas seuls. J'ai passé 3 semaines là-dessus, c'est normal que ce soit compliqué au début.

A plain version of the OSD without annotations can be found here . Introduction Open source doesn’t just mean access to the source code. The distribution terms of open source software must comply with the following criteria: 1. Free Redistribution The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale. Rationale: By constraining the license to require free redistribution, we eliminate the temptation for licensors to throw away many long-term gains to make short-term gains. If we didn’t do this, there would be lots of pressure for cooperators to defect. 2. Source Code The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost, preferably downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed. Rationale: We require access to un-obfuscated source code because you can’t evolve programs without modifying them. Since our purpose is to make evolution easy, we require that modification be made easy. 3. Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software. Rationale: The mere ability to read source isn’t enough to support independent peer review and rapid evolutionary selection. For rapid evolution to happen, people need to be able to experiment with and redistribute modifications. 4. Integrity of The Author’s Source Code The license may restrict source-code from being distributed in modified form only if the license allows the distribution of “patch files” with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software. Rationale: Encouraging lots of improvement is a good thing, but users have a right to know who is responsible for the software they are using. Authors and maintainers have reciprocal right to know what they’re being asked to support and protect their reputations. Accordingly, an open source license must guarantee that source be readily available, but may require that it be distributed as pristine base sources plus patches. In this way, “unofficial” changes can be made available but readily distinguished from the base source. 5. No Discrimination Against Persons or Groups The license must not discriminate against any person or group of persons. Rationale: In order to get the maximum benefit from the process, the maximum diversity of persons and groups should be equally eligible to contribute to open sources. Therefore we forbid any open source license from locking anybody out of the process. Some countries, including the United States, have export restrictions for certain types of software. An OSD-conformant license may warn licensees of applicable restrictions and remind them that they are obliged to obey the law; however, it may not incorporate such restrictions itself. 6. No Discrimination Against Fields of Endeavor The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research. Rationale: The major intention of this clause is to prohibit license traps that prevent open source from being used commercially. We want commercial users to join our community, not feel excluded from it. 7. Distribution of License The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties. Rationale: This clause is intended to forbid closing up software by indirect means such as requiring a non-disclosure agreement. 8. License Must Not Be Specific to a Product The rights attached to the program must not depend on the program’s being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program’s license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution. Rationale: This clause forecloses yet another class of license traps. 9. License Must Not Restrict Other Software The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open source software. Rationale: Distributors of open source software have the right to make their own choices about their own software. Yes, the GPL v2 and v3 are conformant with this requirement. Software linked with GPLed libraries only inherits the GPL if it forms a single work, not any software with which they are merely distributed. 10. License Must Be Technology-Neutral No provision of the license may be predicated on any individual technology or style of interface. Rationale: This provision is aimed specifically at licenses which require an explicit gesture of assent in order to establish a contract between licensor and licensee. Provisions mandating so-called “click-wrap” may conflict with important methods of software distribution such as FTP download, CD-ROM anthologies, and web mirroring; such provisions may also hinder code re-use. Conformant licenses must allow for the possibility that (a) redistribution of the software will take place over non-Web channels that do not support click-wrapping of the download, and that (b) the covered code (or re-used portions of covered code) may run in a non-GUI environment that cannot support popup dialogues. The Open Source Definition was originally derived from the Debian Free Software Guidelines (DFSG).

Report Abuse BeardDemon Posted on Jan 10 J'ai galéré pendant 3 semaines pour monter un cluster Kubernetes (et voilà ce que j'ai appris) # kubernetes # devops # learning Le contexte Bon, soyons honnêtes. Au début, j'avais un gros bordel de scripts bash éparpillés partout. Genre 5-6 fichiers avec des noms comme install-docker.sh , setup-k8s-FINAL-v3.sh (oui, le v3...). À chaque fois que je devais recréer mon infra, c'était 45 minutes de galère + 10 minutes à me demander pourquoi ça marchait pas. J'avais besoin de quelque chose de plus propre pour mon projet SAE e-commerce. Ce que je voulais vraiment Pas un truc de démo avec minikube. Non. Je voulais: 3 VMs qui tournent vraiment (1 master + 2 workers) Tout automatisé - je tape une commande et ça se déploie ArgoCD pour faire du GitOps (parce que push to deploy c'est quand même cool) Des logs centralisés (Loki + Grafana) Et surtout : pouvoir tout péter et tout recréer en 10 minutes L'architecture (spoiler: ça marche maintenant) ┌─────────────────────────────────────────┐ │ Mon PC (Debian) │ │ ┌──────────┐ ┌──────────┐ ┌─────────┐ │ │ Master │ │ Worker 1 │ │ Worker 2│ │ │ .56.10 │ │ .56.11 │ │ .56.12 │ │ └──────────┘ └──────────┘ └─────────┘ └─────────────────────────────────────────┘ Enter fullscreen mode Exit fullscreen mode Chaque VM a 4Go de RAM et 4 CPUs. Oui, ça bouffe des ressources. Non, ça passe pas sur un laptop pourri. Comment c'est organisé J'ai tout mis dans un repo bien rangé (pour une fois): ansible-provisioning/ ├── Vagrantfile # Les 3 VMs ├── playbook.yml # Le chef d'orchestre ├── manifests/ # Mes applis K8s │ ├── apiclients/ │ ├── apicatalogue/ │ ├── databases/ │ └── ... (toutes mes APIs) └── roles/ # Les briques Ansible ├── docker/ ├── kubernetes/ ├── k8s-master/ └── argocd/ Enter fullscreen mode Exit fullscreen mode Chaque rôle fait UN truc. C'est ça qui a changé ma vie. Shell scripts → Ansible : pourquoi j'ai migré Avant (la galère) J'avais un script prepare-system.sh qui ressemblait à ça: #!/bin/bash swapoff -a sed -i '/swap/d' /etc/fstab modprobe br_netfilter # ... 50 lignes de commandes # Aucune gestion d'erreur # Si ça plante au milieu, bonne chance Enter fullscreen mode Exit fullscreen mode Le pire ? Si je relançais le script après un fail, tout pétait. Genre le sed essayait de supprimer une ligne qui existait plus. Classique. Après (je respire enfin) Maintenant j'ai un rôle Ansible system-prepare : - name : Virer le swap shell : swapoff -a ignore_errors : yes - name : Enlever le swap du fstab lineinfile : path : /etc/fstab regexp : ' .*swap.*' state : absent - name : Charger br_netfilter modprobe : name : br_netfilter state : present Enter fullscreen mode Exit fullscreen mode La différence ? Je peux relancer 10 fois, ça fait pas de conneries C'est lisible par un humain Si ça plante, je sais exactement où Le Vagrantfile (ou comment lancer 3 VMs d'un coup) Vagrant . configure ( "2" ) do | config | config . vm . box = "debian/bullseye64" # Config libvirt (KVM/QEMU) config . vm . provider "libvirt" do | libvirt | libvirt . memory = 4096 libvirt . cpus = 4 libvirt . management_network_address = "192.168.56.0/24" end # NFS pour partager les manifests config . vm . synced_folder "." , "/vagrant" , type: "nfs" , nfs_version: 4 # Le master config . vm . define "vm-master" do | vm | vm . vm . network "private_network" , ip: "192.168.56.10" vm . vm . hostname = "master" end # Les 2 workers ( 1 .. 2 ). each do | i | config . vm . define "vm-slave- #{ i } " do | vm | vm . vm . network "private_network" , ip: "192.168.56.1 #{ i } " vm . vm . hostname = "slave- #{ i } " end end # Ansible se lance automatiquement config . vm . provision "ansible" do | ansible | ansible . playbook = "playbook.yml" ansible . groups = { "master" => [ "vm-master" ], "workers" => [ "vm-slave-1" , "vm-slave-2" ] } end end Enter fullscreen mode Exit fullscreen mode Un vagrant up et boom, tout se monte tout seul. Le playbook : l'ordre c'est important --- # 1. Tous les nœuds en même temps - name : Setup de base hosts : k8s_cluster roles : - system-prepare # Swap off, modules kernel - docker # Docker + containerd - kubernetes # kubelet, kubeadm, kubectl # 2. Le master d'abord - name : Init master hosts : master roles : - k8s-master # kubeadm init + Flannel # 3. Les workers ensuite, un par un - name : Join workers hosts : workers serial : 1 # IMPORTANT: un à la fois roles : - k8s-worker # 4. Les trucs bonus sur le master - name : Dashboard + ArgoCD + Monitoring hosts : master roles : - k8s-dashboard - argocd - logging - metrics-server Enter fullscreen mode Exit fullscreen mode Le serial: 1 c'est crucial. J'avais essayé sans, les deux workers essayaient de join en même temps et ça partait en cacahuète. Les rôles en détail Rôle: k8s-master (le chef d'orchestre) C'est lui qui initialise le cluster. Voici les parties importantes: - name : Init cluster k8s command : kubeadm init --apiserver-advertise-address=192.168.56.10 --pod-network-cidr=10.244.0.0/16 when : not k8s_initialise.stat.exists - name : Copier config kubectl copy : src : /etc/kubernetes/admin.conf dest : /home/vagrant/.kube/config owner : vagrant group : vagrant - name : Installer Flannel (réseau pod) shell : | kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml environment : KUBECONFIG : /home/vagrant/.kube/config - name : Générer commande join pour les workers copy : content : " kubeadm join 192.168.56.10:6443 --token {{ k8s_token.stdout }} --discovery-token-ca-cert-hash sha256:{{ k8s_ca_hash.stdout }}" dest : /vagrant/join.sh mode : ' 0755' - name : Créer fichier .master-ready copy : content : " Master initialized" dest : /vagrant/.master-ready Enter fullscreen mode Exit fullscreen mode Le fichier .master-ready c'est un flag pour dire aux workers "go, vous pouvez join maintenant". Rôle: k8s-worker (le suiveur patient) - name : Attendre que le fichier .master-ready existe wait_for : path : /vagrant/.master-ready timeout : 600 - name : Joindre le cluster shell : bash /vagrant/join.sh args : creates : /etc/kubernetes/kubelet.conf register : join_result failed_when : - join_result.rc != 0 - " 'already exists in the cluster' not in join_result.stderr" - name : Attendre que le node soit Ready shell : | for i in {1..60}; do STATUS=$(kubectl get node $(hostname) -o jsonpath='{.status.conditions[?(@.type=="Ready")].status}') if [ "$STATUS" = "True" ]; then exit 0 fi sleep 5 done exit 1 Enter fullscreen mode Exit fullscreen mode Le worker attend gentiment que le master soit prêt avant de faire quoi que ce soit. Les galères que j'ai rencontrées Galère #1: NFS qui marche pas Au début, le partage NFS entre l'hôte et les VMs plantait. Symptôme: mount.nfs: Connection timed out Enter fullscreen mode Exit fullscreen mode Solution: # Sur l'hôte sudo apt install nfs-kernel-server sudo systemctl start nfs-server sudo ufw allow from 192.168.56.0/24 Enter fullscreen mode Exit fullscreen mode Le firewall bloquait les connexions NFS. Classique. Galère #2: Kubeadm qui timeout Le kubeadm init prenait 10 minutes et finissait par timeout. Cause: Pas assez de RAM sur les VMs (j'avais mis 2Go). Solution: Passer à 4Go par VM. Ça bouffe mais c'est nécessaire. Galère #3: Les workers qui join pas Les workers restaient en NotReady même après le join. Cause: Flannel (le CNI) était pas encore installé sur le master. Solution: Attendre que Flannel soit complètement déployé avant de faire join les workers: - name : Attendre Flannel command : kubectl wait --for=condition=ready pod -l app=flannel -n kube-flannel --timeout=300s environment : KUBECONFIG : /etc/kubernetes/admin.conf Enter fullscreen mode Exit fullscreen mode Galère #4: Ansible qui relance tout à chaque fois Au début, chaque vagrant provision refaisait TOUT depuis zéro. Solution: Ajouter des conditions when partout: - name : Init cluster k8s command : kubeadm init ... when : not k8s_initialise.stat.exists # ← Ça sauve des vies Enter fullscreen mode Exit fullscreen mode L'idempotence c'est vraiment la base avec Ansible. Les commandes utiles au quotidien # Lancer tout cd ansible-provisioning && vagrant up # Vérifier l'état du cluster vagrant ssh vm-master -c 'kubectl get nodes' # Voir les pods vagrant ssh vm-master -c 'kubectl get pods -A' # Refaire le provisioning (sans détruire les VMs) vagrant provision # Tout péter et recommencer vagrant destroy -f && vagrant up # SSH sur le master vagrant ssh vm-master # Logs d'un pod vagrant ssh vm-master -c 'kubectl logs -n apps apicatalogue-xyz' Enter fullscreen mode Exit fullscreen mode ArgoCD et les applications Une fois le cluster monté, ArgoCD déploie automatiquement mes apps. Voici comment je déclare l'API Catalogue: apiVersion : argoproj.io/v1alpha1 kind : Application metadata : name : catalogue-manager-application namespace : argocd spec : destination : namespace : apps server : https://kubernetes.default.svc source : path : ansible-provisioning/manifests/apicatalogue repoURL : https://github.com/uha-sae53/Vagrant.git targetRevision : main project : default syncPolicy : automated : prune : true selfHeal : true Enter fullscreen mode Exit fullscreen mode ArgoCD surveille mon repo GitHub. Dès que je change un manifest, ça se déploie automatiquement. Metrics Server et HPA J'ai aussi ajouté le Metrics Server pour l'auto-scaling: - name : Installer Metrics Server shell : | kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml environment : KUBECONFIG : /etc/kubernetes/admin.conf - name : Patcher pour ignorer TLS (dev seulement) shell : | kubectl patch deployment metrics-server -n kube-system --type='json' \ -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--kubelet-insecure-tls"}]' Enter fullscreen mode Exit fullscreen mode Avec ça, mes pods peuvent scaler automatiquement en fonction de la charge CPU/RAM. Le résultat final Après tout ça, voici ce que je peux faire: # Démarrer tout de zéro vagrant up # ⏱️ 8 minutes plus tard... # Vérifier que tout tourne vagrant ssh vm-master -c 'kubectl get pods -A' # Résultat: # NAMESPACE NAME READY STATUS # apps apicatalogue-xyz 1/1 Running # apps apiclients-abc 1/1 Running # apps apicommandes-def 1/1 Running # apps api-panier-ghi 1/1 Running # apps frontend-jkl 1/1 Running # argocd argocd-server-xxx 1/1 Running # logging grafana-yyy 1/1 Running # logging loki-0 1/1 Running # kube-system metrics-server-zzz 1/1 Running Enter fullscreen mode Exit fullscreen mode Tout fonctionne, tout est automatisé. Conclusion Ce que j'ai appris: Ansible > scripts shell (vraiment, vraiment) L'idempotence c'est pas un luxe Tester chaque rôle séparément avant de tout brancher Les workers doivent attendre le master (le serial: 1 sauve des vies) 4Go de RAM minimum par VM pour K8s Le code complet est sur GitHub: https://github.com/uha-sae53/Vagrant Des questions ? Ping moi sur Twitter ou ouvre une issue sur le repo. Et si vous galérez avec Kubernetes, vous êtes pas seuls. J'ai passé 3 semaines là-dessus, c'est normal que ce soit compliqué au début.

Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content. Helpful Resources Below you'll find various resources we recommend for better understanding DEV's writing policies and tools.

The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content.

Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content.

The request context allows highlight to associate logs with the incoming frontend session and network request. logrus.WithContext(ctx).WithField("user", "bob").Infof("hello, %s!", "world") 3 Call the Highlight logging SDK. Use our SDK to configure logrus , and use it as normal. package main import ( "context" "github.com/highlight/highlight/sdk/highlight-go" "github.com/highlight/highlight/sdk/highlight-go/log" "github.com/sirupsen/logrus" ) func main() { // setup the highlight SDK highlight.SetProjectID("<YOUR_PROJECT_ID>") highlight.Start( highlight.WithServiceName("my-app"), highlight.WithServiceVersion("git-sha"), ) defer highlight.Stop() // setup highlight logrus hook hlog.Init() // if you don't want to get stdout / stderr output, add the following uncommented // hlog.DisableOutput() // if in a request, provide context to associate logs with frontend sessions ctx := context.TODO() // send logs logrus.WithContext(ctx).WithField("hello", "world").Info("welcome to highlight.io") // send logs with a string message severity lvl, _ := logrus.ParseLevel("warn") logrus.WithContext(ctx).Log(lvl, "whoa there") } 4 Verify your backend logs are being recorded.

Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog.

Report Abuse BeardDemon Posted on Jan 10 J'ai galéré pendant 3 semaines pour monter un cluster Kubernetes (et voilà ce que j'ai appris) # kubernetes # devops # learning Le contexte Bon, soyons honnêtes. Au début, j'avais un gros bordel de scripts bash éparpillés partout. Genre 5-6 fichiers avec des noms comme install-docker.sh , setup-k8s-FINAL-v3.sh (oui, le v3...). À chaque fois que je devais recréer mon infra, c'était 45 minutes de galère + 10 minutes à me demander pourquoi ça marchait pas. J'avais besoin de quelque chose de plus propre pour mon projet SAE e-commerce. Ce que je voulais vraiment Pas un truc de démo avec minikube. Non. Je voulais: 3 VMs qui tournent vraiment (1 master + 2 workers) Tout automatisé - je tape une commande et ça se déploie ArgoCD pour faire du GitOps (parce que push to deploy c'est quand même cool) Des logs centralisés (Loki + Grafana) Et surtout : pouvoir tout péter et tout recréer en 10 minutes L'architecture (spoiler: ça marche maintenant) ┌─────────────────────────────────────────┐ │ Mon PC (Debian) │ │ ┌──────────┐ ┌──────────┐ ┌─────────┐ │ │ Master │ │ Worker 1 │ │ Worker 2│ │ │ .56.10 │ │ .56.11 │ │ .56.12 │ │ └──────────┘ └──────────┘ └─────────┘ └─────────────────────────────────────────┘ Enter fullscreen mode Exit fullscreen mode Chaque VM a 4Go de RAM et 4 CPUs. Oui, ça bouffe des ressources. Non, ça passe pas sur un laptop pourri. Comment c'est organisé J'ai tout mis dans un repo bien rangé (pour une fois): ansible-provisioning/ ├── Vagrantfile # Les 3 VMs ├── playbook.yml # Le chef d'orchestre ├── manifests/ # Mes applis K8s │ ├── apiclients/ │ ├── apicatalogue/ │ ├── databases/ │ └── ... (toutes mes APIs) └── roles/ # Les briques Ansible ├── docker/ ├── kubernetes/ ├── k8s-master/ └── argocd/ Enter fullscreen mode Exit fullscreen mode Chaque rôle fait UN truc. C'est ça qui a changé ma vie. Shell scripts → Ansible : pourquoi j'ai migré Avant (la galère) J'avais un script prepare-system.sh qui ressemblait à ça: #!/bin/bash swapoff -a sed -i '/swap/d' /etc/fstab modprobe br_netfilter # ... 50 lignes de commandes # Aucune gestion d'erreur # Si ça plante au milieu, bonne chance Enter fullscreen mode Exit fullscreen mode Le pire ? Si je relançais le script après un fail, tout pétait. Genre le sed essayait de supprimer une ligne qui existait plus. Classique. Après (je respire enfin) Maintenant j'ai un rôle Ansible system-prepare : - name : Virer le swap shell : swapoff -a ignore_errors : yes - name : Enlever le swap du fstab lineinfile : path : /etc/fstab regexp : ' .*swap.*' state : absent - name : Charger br_netfilter modprobe : name : br_netfilter state : present Enter fullscreen mode Exit fullscreen mode La différence ? Je peux relancer 10 fois, ça fait pas de conneries C'est lisible par un humain Si ça plante, je sais exactement où Le Vagrantfile (ou comment lancer 3 VMs d'un coup) Vagrant . configure ( "2" ) do | config | config . vm . box = "debian/bullseye64" # Config libvirt (KVM/QEMU) config . vm . provider "libvirt" do | libvirt | libvirt . memory = 4096 libvirt . cpus = 4 libvirt . management_network_address = "192.168.56.0/24" end # NFS pour partager les manifests config . vm . synced_folder "." , "/vagrant" , type: "nfs" , nfs_version: 4 # Le master config . vm . define "vm-master" do | vm | vm . vm . network "private_network" , ip: "192.168.56.10" vm . vm . hostname = "master" end # Les 2 workers ( 1 .. 2 ). each do | i | config . vm . define "vm-slave- #{ i } " do | vm | vm . vm . network "private_network" , ip: "192.168.56.1 #{ i } " vm . vm . hostname = "slave- #{ i } " end end # Ansible se lance automatiquement config . vm . provision "ansible" do | ansible | ansible . playbook = "playbook.yml" ansible . groups = { "master" => [ "vm-master" ], "workers" => [ "vm-slave-1" , "vm-slave-2" ] } end end Enter fullscreen mode Exit fullscreen mode Un vagrant up et boom, tout se monte tout seul. Le playbook : l'ordre c'est important --- # 1. Tous les nœuds en même temps - name : Setup de base hosts : k8s_cluster roles : - system-prepare # Swap off, modules kernel - docker # Docker + containerd - kubernetes # kubelet, kubeadm, kubectl # 2. Le master d'abord - name : Init master hosts : master roles : - k8s-master # kubeadm init + Flannel # 3. Les workers ensuite, un par un - name : Join workers hosts : workers serial : 1 # IMPORTANT: un à la fois roles : - k8s-worker # 4. Les trucs bonus sur le master - name : Dashboard + ArgoCD + Monitoring hosts : master roles : - k8s-dashboard - argocd - logging - metrics-server Enter fullscreen mode Exit fullscreen mode Le serial: 1 c'est crucial. J'avais essayé sans, les deux workers essayaient de join en même temps et ça partait en cacahuète. Les rôles en détail Rôle: k8s-master (le chef d'orchestre) C'est lui qui initialise le cluster. Voici les parties importantes: - name : Init cluster k8s command : kubeadm init --apiserver-advertise-address=192.168.56.10 --pod-network-cidr=10.244.0.0/16 when : not k8s_initialise.stat.exists - name : Copier config kubectl copy : src : /etc/kubernetes/admin.conf dest : /home/vagrant/.kube/config owner : vagrant group : vagrant - name : Installer Flannel (réseau pod) shell : | kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml environment : KUBECONFIG : /home/vagrant/.kube/config - name : Générer commande join pour les workers copy : content : " kubeadm join 192.168.56.10:6443 --token {{ k8s_token.stdout }} --discovery-token-ca-cert-hash sha256:{{ k8s_ca_hash.stdout }}" dest : /vagrant/join.sh mode : ' 0755' - name : Créer fichier .master-ready copy : content : " Master initialized" dest : /vagrant/.master-ready Enter fullscreen mode Exit fullscreen mode Le fichier .master-ready c'est un flag pour dire aux workers "go, vous pouvez join maintenant". Rôle: k8s-worker (le suiveur patient) - name : Attendre que le fichier .master-ready existe wait_for : path : /vagrant/.master-ready timeout : 600 - name : Joindre le cluster shell : bash /vagrant/join.sh args : creates : /etc/kubernetes/kubelet.conf register : join_result failed_when : - join_result.rc != 0 - " 'already exists in the cluster' not in join_result.stderr" - name : Attendre que le node soit Ready shell : | for i in {1..60}; do STATUS=$(kubectl get node $(hostname) -o jsonpath='{.status.conditions[?(@.type=="Ready")].status}') if [ "$STATUS" = "True" ]; then exit 0 fi sleep 5 done exit 1 Enter fullscreen mode Exit fullscreen mode Le worker attend gentiment que le master soit prêt avant de faire quoi que ce soit. Les galères que j'ai rencontrées Galère #1: NFS qui marche pas Au début, le partage NFS entre l'hôte et les VMs plantait. Symptôme: mount.nfs: Connection timed out Enter fullscreen mode Exit fullscreen mode Solution: # Sur l'hôte sudo apt install nfs-kernel-server sudo systemctl start nfs-server sudo ufw allow from 192.168.56.0/24 Enter fullscreen mode Exit fullscreen mode Le firewall bloquait les connexions NFS. Classique. Galère #2: Kubeadm qui timeout Le kubeadm init prenait 10 minutes et finissait par timeout. Cause: Pas assez de RAM sur les VMs (j'avais mis 2Go). Solution: Passer à 4Go par VM. Ça bouffe mais c'est nécessaire. Galère #3: Les workers qui join pas Les workers restaient en NotReady même après le join. Cause: Flannel (le CNI) était pas encore installé sur le master. Solution: Attendre que Flannel soit complètement déployé avant de faire join les workers: - name : Attendre Flannel command : kubectl wait --for=condition=ready pod -l app=flannel -n kube-flannel --timeout=300s environment : KUBECONFIG : /etc/kubernetes/admin.conf Enter fullscreen mode Exit fullscreen mode Galère #4: Ansible qui relance tout à chaque fois Au début, chaque vagrant provision refaisait TOUT depuis zéro. Solution: Ajouter des conditions when partout: - name : Init cluster k8s command : kubeadm init ... when : not k8s_initialise.stat.exists # ← Ça sauve des vies Enter fullscreen mode Exit fullscreen mode L'idempotence c'est vraiment la base avec Ansible. Les commandes utiles au quotidien # Lancer tout cd ansible-provisioning && vagrant up # Vérifier l'état du cluster vagrant ssh vm-master -c 'kubectl get nodes' # Voir les pods vagrant ssh vm-master -c 'kubectl get pods -A' # Refaire le provisioning (sans détruire les VMs) vagrant provision # Tout péter et recommencer vagrant destroy -f && vagrant up # SSH sur le master vagrant ssh vm-master # Logs d'un pod vagrant ssh vm-master -c 'kubectl logs -n apps apicatalogue-xyz' Enter fullscreen mode Exit fullscreen mode ArgoCD et les applications Une fois le cluster monté, ArgoCD déploie automatiquement mes apps. Voici comment je déclare l'API Catalogue: apiVersion : argoproj.io/v1alpha1 kind : Application metadata : name : catalogue-manager-application namespace : argocd spec : destination : namespace : apps server : https://kubernetes.default.svc source : path : ansible-provisioning/manifests/apicatalogue repoURL : https://github.com/uha-sae53/Vagrant.git targetRevision : main project : default syncPolicy : automated : prune : true selfHeal : true Enter fullscreen mode Exit fullscreen mode ArgoCD surveille mon repo GitHub. Dès que je change un manifest, ça se déploie automatiquement. Metrics Server et HPA J'ai aussi ajouté le Metrics Server pour l'auto-scaling: - name : Installer Metrics Server shell : | kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml environment : KUBECONFIG : /etc/kubernetes/admin.conf - name : Patcher pour ignorer TLS (dev seulement) shell : | kubectl patch deployment metrics-server -n kube-system --type='json' \ -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value": "--kubelet-insecure-tls"}]' Enter fullscreen mode Exit fullscreen mode Avec ça, mes pods peuvent scaler automatiquement en fonction de la charge CPU/RAM. Le résultat final Après tout ça, voici ce que je peux faire: # Démarrer tout de zéro vagrant up # ⏱️ 8 minutes plus tard... # Vérifier que tout tourne vagrant ssh vm-master -c 'kubectl get pods -A' # Résultat: # NAMESPACE NAME READY STATUS # apps apicatalogue-xyz 1/1 Running # apps apiclients-abc 1/1 Running # apps apicommandes-def 1/1 Running # apps api-panier-ghi 1/1 Running # apps frontend-jkl 1/1 Running # argocd argocd-server-xxx 1/1 Running # logging grafana-yyy 1/1 Running # logging loki-0 1/1 Running # kube-system metrics-server-zzz 1/1 Running Enter fullscreen mode Exit fullscreen mode Tout fonctionne, tout est automatisé. Conclusion Ce que j'ai appris: Ansible > scripts shell (vraiment, vraiment) L'idempotence c'est pas un luxe Tester chaque rôle séparément avant de tout brancher Les workers doivent attendre le master (le serial: 1 sauve des vies) 4Go de RAM minimum par VM pour K8s Le code complet est sur GitHub: https://github.com/uha-sae53/Vagrant Des questions ? Ping moi sur Twitter ou ouvre une issue sur le repo. Et si vous galérez avec Kubernetes, vous êtes pas seuls. J'ai passé 3 semaines là-dessus, c'est normal que ce soit compliqué au début.

Report Abuse Jaeil Woo Posted on Jan 11 Building a "Remembering" AI Trading Agent with Python, LangGraph, and Obsidian # ai # machinelearning # python # opensource Hello DEV community! I'm excited to share an open-source project I've been working on: TradingAgents-Dashboard . It's a Dockerized AI trading assistant that not only analyzes the market but remembers your insights forever using a local knowledge base (RAG). The Problem: "Stateless" AI Most AI trading bots today are "stateless". They run an analysis, give you a result, and then forget everything the moment you close the terminal. "Wait, didn't we decide last week that inflation correlates with this stock?" "Where is that news link I saw yesterday?" As a developer and trader, I wanted an agent that grows smarter over time, just like a human analyst. The Solution: AI + Obsidian (RAG) I built a dashboard wrapping the TradingAgents framework, adding a persistent memory layer using Obsidian . Github Repo: jiwoomap/TradingAgents-Dashboard How it works: Analyze: Agents (Bull, Bear, Risk Manager) debate market conditions using LangGraph. Persist: All insights and debates are auto-saved to your local Obsidian Vault as Markdown files. Recall (RAG): Before making a new decision, the agents search your vault (via ChromaDB) to retrieve past lessons and context. Tech Stack Framework: LangChain / LangGraph (Multi-Agent Orchestration) UI: Streamlit (Web Dashboard) Database: ChromaDB (Vector Store for RAG) Memory: Obsidian (Markdown-based Knowledge Base) Infrastructure: Docker & Docker Compose Key Features Interactive Debate UI: Watch the "Bull" and "Bear" agents fight it out in real-time. Fact Checker: Prevents hallucinations by validating news URLs (200 OK checks). Dockerized: Get started in 1 minute with docker-compose up . Data Sovereignty: Your financial data and strategies live on your disk , not in a cloud database. Try it out! I'd love to get your feedback. If you're interested in AI Agents or FinTech, give it a spin!

Report Abuse Q1Hang Posted on Jan 13 Building an AI Photo Restoration Tool with Next.js # webdev # programming # ai # beginners Introduction Hi everyone, I built AIsynapse( https://www.aisynapse.dev/ ) - an AI-powered photo restoration tool as a solo side project. What It Does The web app restores scratched, torn, and faded photos using AI models. Users can upload photos, choose from multiple restoration modes for different types of damage, and download enhanced images in seconds. Everything runs in the browser - no installation needed. Tech Stack Frontend/Backend: Next.js 15 with App Router Database: PostgreSQL with Drizzle ORM Authentication: Better Auth (email + Google OAuth) Payments: Stripe for credit packages Storage: AWS S3 for file uploads AI: Multiple providers for restoration quality Business Model I went with a credit-based pricing system: New users get 1 free restoration Daily login bonus credits to encourage retention Three credit packages: $4.90 for 50 photos $9.90 for 120 photos $19.90 for 300 photos Each restoration costs 10 credits, making it cost-effective for bulk restoration work. Results The restoration quality has been solid. Photos with scratches, tears, fading, and water damage can be restored in seconds. Multiple restoration modes let users choose the right tool for their specific type of damage. Try It Out Check it out at https://www.aisynapse.dev/ new users get 1 free restoration, no credit card required. Questions? Feedback? Let me know in the comments!

Check out the courses Advert Time makes fools of us all, and JavaScript is no slouch in that department either. Honestly, I’ve never minded the latter much — in fact, if you’ve taken JavaScript for Everyone or tuned into the newsletter , you already know that I largely enjoy JavaScript’s little quirks, believe it or not. I like when you can see the seams; I like how, for as formal and iron-clad as the ES-262 specification might seem, you can still see all the good and bad decisions made by the hundreds of people who’ve been building the language in mid-flight, if you know where to look. JavaScript has character . Sure, it doesn’t necessarily do everything exactly the way one might expect, but y’know, if you ask me, JavaScript has a real charm once you get to know it! There’s one part of the language where that immediately falls apart for me, though. Code language js Copy to clipboard // Numeric months are zero-indexed, but years and days are not: console . log ( new Date ( 2026 , 1 , 1 ) ) ; // Result: Date Sun Feb 01 2026 00:00:00 GMT-0500 (Eastern Standard Time) The Date constructor. Code language js Copy to clipboard // A numeric string between 32 and 49 is assumed to be in the 2000s: console . log ( new Date ( "49" ) ) ; // Result: Date Fri Jan 01 2049 00:00:00 GMT-0500 (Eastern Standard Time) // A numeric string between 33 and 99 is assumed to be in the 1900s: console . log ( new Date ( "99" ) ) ; // Result: Date Fri Jan 01 1999 00:00:00 GMT-0500 (Eastern Standard Time) // ...But 100 and up start from year zero: console . log ( new Date ( "100" ) ) ; // Result: Date Fri Jan 01 0100 00:00:00 GMT-0456 (Eastern Standard Time) I dislike Date immensely . Code language js Copy to clipboard // A string-based date works the way you might expect: console . log ( new Date ( "2026/1/2" ) ) ; // Result: Date Fri Jan 02 2026 00:00:00 GMT-0500 (Eastern Standard Time) // A leading zero on the month? No problem; one is one, right? console . log ( new Date ( "2026/02/2" ) ) ; // Result: Date Mon Feb 02 2026 00:00:00 GMT-0500 (Eastern Standard Time) // Slightly different formatting? Sure! console . log ( new Date ( "2026-02-2" ) ) ; // Result: Date Mon Feb 02 2026 00:00:00 GMT-0500 (Eastern Standard Time) // A leading zero on the day? Of course; why wouldn't it work? console . log ( new Date ( '2026/01/02' ) ) ; // Result: Date Fri Jan 02 2026 00:00:00 GMT-0500 (Eastern Standard Time) // Unless, of course, you separate the year, month, and date with hyphens. // Then it gets the _day_ wrong. console . log ( new Date ( '2026-01-02' ) ) ; // Result: Date Thu Jan 01 2026 19:00:00 GMT-0500 (Eastern Standard Time) Date sucks. It was hastily and shamelessly copied off of Java’s homework in the car on the way to school and it got all the same answers wrong, right down to the name at the top of the page: Date doesn’t represent a date , it represents a time . Internally, dates are stored as number values called time values : Unix timestamps, divided into 1,000 milliseconds — which, okay, yes, a Unix time does also necessarily imply a date, sure, but still : Date represents a time, from which you can infer a date. Gross. Code language js Copy to clipboard // Unix timestamp for Monday, December 4, 1995 12:00:00 AM GMT-05 (the day JavaScript was announced): const timestamp = 818053200 ; console . log ( new Date ( timestamp * 1000 ) ) ; // Result: Date Mon Dec 04 1995 00:00:00 GMT-0500 (Eastern Standard Time) Words like “date” and “time” mean things, but, sure — whatever, JavaScript . Java deprecated their Date way back in 1997, only a few years after JavaScript’s Date was turned loose on the unsuspecting world; meanwhile, we’ve been saddled with this mess ever since. It’s wildly inconsistent when it comes to parsing dates, as you’ve seen so far here. It has no sense of time zones beyond the local one and GMT, which is not ideal where “world-wide” is right there in the web’s name — and speaking-of, Date only respects the Gregorian calendar model. It wholesale does not understand the concept of daylight savings time, which— I mean, okay, yeah, samesies, but I’m not made of computers . All these shortcomings make it exceptionally common to use a third-party library dedicated to working around it all, some of which are absolutely massive ; a performance drain that has done real and measurable damage to the web. None of these are my major issue with Date . My complaint is about more than parsing or syntax or “developer ergonomics” or the web-wide performance impact of wholly necessary workarounds or even the definition of the word “date.” My issue with Date is soul-deep. My problem with Date is that using it means deviating from the fundamental nature of time itself . Advert All JavaScript’s primitives values are immutable , meaning that the values themselves cannot be changed. The number value 3 can never represent anything but the concept of “three” — you can’t make true mean anything other than “true.” These are values with concrete, iron-clad, real-world meanings. We know what three is. It can’t be some other non-three thing. These immutable data types are stored by value , meaning that a variable that represents the number value 3 effectively “contains” — and thus behaves as — the number value 3 . When an immutable value is assigned to a variable, the JavaScript engine creates a copy of that value and stores the copy in memory: Code language js Copy to clipboard const theNumber = 3 ; console . log ( theNumber ) ; // Result: 3 This fits the common mental model for “a variable” just fine: theNumber “contains” 3 . When we initialize theOtherNumber with the value bound to theNumber , that mental model holds: once again a 3 is created and stored in memory. theOtherNumber can now be thought of as containing its own discrete 3 . Code language js Copy to clipboard const theNumber = 3 ; const theOtherNumber = theNumber ; console . log ( theOtherNumber ) ; // Result: 3; The value of theNumber isn’t changed when we alter the value associated with theOtherNumber , of course — again, we’re working with two discrete instances of 3 . Code language js Copy to clipboard const theNumber = 3 ; let theOtherNumber = theNumber ; theOtherNumber = 5 ; console . log ( theOtherNumber ) ; // Result: 5; console . log ( theNumber ) ; // Result: 3 When you change the value bound to theOtherNumber , you’re not changing the 3 , you’re creating a new, immutable number value and binding that in its place. Hence an error when you try to tinker with a variable declared using const : Code language js Copy to clipboard const theNumber = 3 ; theNumber = 5 ; // Result: Uncaught TypeError: invalid assignment to const 'theNumber' You can’t change the binding of a const , and you definitely can’t alter the meaning of 3 . Data types that can be changed after they’re created are mutable , meaning that the data value itself can be altered. Object values — any non-primitive value, like an array, map, or set — are mutable. Variables (and object properties, function parameters, and elements in an array, set, or map) can’t “contain” an object, the way we might think of theNumber in the example above as “containing” 3 . A variable can contain either a primitive value or a reference value , the latter of which is a pointer to that object’s stored location in memory. When you assign an object to a variable, instead of creating a copy of that object, the identifier represents a reference to the object’s stored position in memory. That’s why an object bound to a variable declared with const can still be altered: the reference value can’t be changed, but the values of the object can: Code language js Copy to clipboard const theObject = { theValue : 3 } ; theObject . theValue ++ ; console . log ( theObject . theValue ) ; // Result: 4 You still can’t change the binding of a const , but you can alter the object that binding references. When a reference value is assigned from one variable to another, the JavaScript engine creates a copy of that reference value — not the object value itself, the way a discrete copy is made of a primitive value. Both identifiers point to the same object in memory — any changes made to that object by way of one reference will be reflected by the others, because they’re all referencing the same thing: Code language js Copy to clipboard const theObject = { theValue : 3 } ; const theOtherObj = theObject ; theOtherObj . theValue ++ ; console . log ( theOtherObj . theValue ) ; // Result: 4 console . log ( theObject . theValue ) ; // Result: 4 This is what gets me about JavaScript’s date handling. Despite representing “point to it on a calendar” values, JavaScript’s date values are mutable — Date is a constructor, invoking a constructor with new necessarily results in an object, and all objects are inherently mutable: Code language js Copy to clipboard const theDate = new Date ( ) ; console . log ( typeof theDate ) ; // Result: object Even though “January 1st, 2026” is as much an immutable real-world concept as “three” or “true,” the only way we have of representing that date is a with a mutable data structure. This also means that any variable initialized with an instance of the Date constructor contains a reference value, pointing to a data value in memory that can be changed by way of any reference to that value: Code language js Copy to clipboard const theDate = new Date ( ) ; console . log ( theDate . toDateString ( ) ) ; // Result: Tue Dec 30 2025 theDate . setMonth ( 10 ) ; console . log ( theDate . toDateString ( ) ) ; // Result: Sun Nov 30 2025 Again, we’re going to breeze right over the fact that month 10 is November . So despite real-world dates having set-in-stone meanings , the process of interacting with an instance of Date that represents that real-world value can mean altering that instance in ways we didn’t necessarily intend: Code language js Copy to clipboard const today = new Date ( ) ; const addDay = theDate => { theDate . setDate ( theDate . getDate ( ) + 1 ) ; return theDate ; } ; console . log ( ` Today is ${ today . toLocaleDateString ( ) } , tomorrow is ${ addDay ( today ) . toLocaleDateString ( ) } . ` ) ; // Result: Today is 12/31/2025. Tomorrow is 1/1/2026. Fine so far, right? Today is today, tomorrow is tomorrow; all is right in the world. You’d be forgiven for committing this to a codebase and moving on with your day. That is, unless we reordered the output slightly. Code language js Copy to clipboard const today = new Date ( ) ; const addDay = theDate => { theDate . setDate ( theDate . getDate ( ) + 1 ) ; return theDate ; } ; console . log ( ` Tomorrow will be ${ addDay ( today ) . toLocaleDateString ( ) } . Today is ${ today . toLocaleDateString ( ) } . ` ) ; // Result: Tomorrow will be 1/1/2026. Today is 1/1/2026. See what happened there? the variable today represents a reference to the object created by new Date() . When we provided today as an argument to the addDay function, the parameter theDate now represents a copy of the reference value — not a copy of the value, but a second reference to the object that represents today’s date. When we manipulate that value to determine the date of the following day, we’re manipulating the mutable object in memory, not an immutable copy — today becomes tomorrow, the falcon has a hard time hearing the falconer, the center starts to look a little iffy vis-a-vis “holding,” and so on. Now, by this point you can probably tell that I’m not here to praise Date , but what you might not expect is that I’m here to bury it. That’s right: Date is soon to be over, done, gone, as “deprecated” as any part of the web platform can be — which is to say, “around forever, but you shouldn’t use it anymore, if you can avoid it.” Soon we will — at long last — have an object that replaces Date wholesale: Temporal . Advert Temporal is not a constructor, it’s a namespace object The sharp-eyed among you may have noticed that I said “an object that replaces Date ,” not “a constructor.” Temporal is not a constructor, and your browser’s developer console will tell you the same if you attempt to invoke it as one: Code language js Copy to clipboard const today = new Temporal ( ) ; // Uncaught TypeError: Temporal is not a constructor Temporal is a way better name for something that pertains to time , if you ask me. Instead, Temporal is a namespace object — an ordinary object made up of static properties and methods, like the Math object: Code language js Copy to clipboard console . log ( Temporal ) ; /* Result (expanded): Temporal { … } Duration: function Duration() Instant: function Instant() Now: Temporal.Now { … } PlainDate: function PlainDate() PlainDateTime: function PlainDateTime() PlainMonthDay: function PlainMonthDay() PlainTime: function PlainTime() PlainYearMonth: function PlainYearMonth() ZonedDateTime: function ZonedDateTime() Symbol(Symbol.toStringTag): "Temporal" */ I find this immediately understandable compared to Date . The classes and namespaces objects that Temporal contains allow you to calculate durations between two points in time, represent a point in time with or without time zone specificity , or access the current moment in time via the Now property. Temporal.Now references a namespace object containing properties and methods of its own: Code language js Copy to clipboard console . log ( Temporal . Now ) ; /* Result (expanded): Temporal.Now { … } instant: function instant() plainDateISO: function plainDateISO() plainDateTimeISO: function plainDateTimeISO() plainTimeISO: function plainTimeISO() timeZoneId: function timeZoneId() zonedDateTimeISO: function zonedDateTimeISO() Symbol(Symbol.toStringTag): "Temporal.Now" <prototype>: Object { … } */ Temporal gives us a sensible, plain-language way to grab today’s date, a la raggedy old Date : the Now property contains a plainDateISO() method. Since we’re not specifying anything in the way of time zones (a thing we can do now, thanks to Temporal) that method gives us back today’s date in the current one — EST, in my case: Code language js Copy to clipboard console . log ( Temporal . Now . plainDateISO ( ) ) ; /* Result (expanded): Temporal.PlainDate 2025-12-31 <prototype>: Object { … } */ Notice how plainDateISO results in an already-formatted, date-only value? Stay tuned; that’ll come up again later. —wait. That looks familiar: Code language js Copy to clipboard const nowTemporal = Temporal . Now . plainDateISO ( ) ; const nowDate = new Date ( ) ; console . log ( nowTemporal ) ; /* Result (expanded): Temporal.PlainDate 2025-12-31 <prototype>: Object { … } */ console . log ( nowDate ) ; /* Result (expanded): Date Tue Dec 31 2025 11:05:52 GMT-0500 (Eastern Standard Time) <prototype>: Date.prototype { … } */ Could it be that—… Code language js Copy to clipboard const rightNow = Temporal . Now . instant ( ) ; console . log ( typeof rightNow ) ; // object Yes, we’re still working with a mutable object that represents the current date , I say in my spookiest voice, flashlight squarely beneath my chin. At a glance, this might not seem like it addresses my big complaint with Date at all. Well, we’re kind of at the mercy of the nature of the language, here: dates represent complex real-world values, complex data necessitates complex data structures, and for JavaScript, that means objects. The difference is in how we interact with these Temporal objects, as compared to instances of Date , and — as is so often the case — the magic is in the prototype chain: Code language js Copy to clipboard const nowTemporal = Temporal . Now . plainDateISO ( ) ; console . log ( nowTemporal . __proto__ ) ; /* Result (expanded): Object { … } add: function add() calendarId: >> constructor: function PlainDate() day: >> dayOfWeek: >> dayOfYear: >> daysInMonth: >> daysInWeek: >> daysInYear: >> equals: function equals() era: >> eraYear: >> inLeapYear: >> month: >> monthCode: >> monthsInYear: >> since: function since() subtract: function subtract() toJSON: function toJSON() toLocaleString: function toLocaleString() toPlainDateTime: function toPlainDateTime() toPlainMonthDay: function toPlainMonthDay() toPlainYearMonth: function toPlainYearMonth() toString: function toString() toZonedDateTime: function toZonedDateTime() until: function until() valueOf: function valueOf() weekOfYear: >> with: function with() withCalendar: function withCalendar() year: >> yearOfWeek: >> Symbol(Symbol.toStringTag): "Temporal.PlainDate" <get calendarId()>: function calendarId() <get day()>: function day() <get dayOfWeek()>: function dayOfWeek() <get dayOfYear()>: function dayOfYear() <get daysInMonth()>: function daysInMonth() <get daysInWeek()>: function daysInWeek() <get daysInYear()>: function daysInYear() <get era()>: function era() <get eraYear()>: function eraYear() <get inLeapYear()>: function inLeapYear() */ Right away you’ll notice that there are a number of methods and properties devoted to accessing, formatting, and manipulating the details of the Temporal object we’re working with. No big surprises there — it means a little bit of a learning curve, sure, but nothing an occasional trip over to MDN couldn’t solve, and they all more-or-less do what they say on their respective tins. The big difference from working with Date is how they do so, at a fundamental level: Code language js Copy to clipboard const nowTemporal = Temporal . Now . plainDateISO ( ) ; // Current local date: console . log ( nowTemporal ) ; /* Result (expanded): Temporal.PlainDate 2025-12-30 <prototype>: Object { … } */ // Current local year: console . log ( nowTemporal . year ) ; // Result: 2025 // Current local date and time: console . log ( nowTemporal . toPlainDateTime ( ) ) ; /* Result (expanded): Temporal.PlainDateTime 2025-12-30T00:00:00 <prototype>: Object { … } */ // Specify that this date represents the Europe/London time zone: console . log ( nowTemporal . toZonedDateTime ( "Europe/London" ) ) ; /* Result (expanded): Temporal.ZonedDateTime 2025-12-30T00:00:00+00:00[Europe/London] <prototype>: Object { … } */ // Add a day to this date: console . log ( nowTemporal . add ( { days : 1 } ) ) ; /* Temporal.PlainDate 2025-12-31 <prototype>: Object { … } */ // Add one month and one day to this date, and subtract two years: console . log ( nowTemporal . add ( { months : 1 , days : 1 } ) . subtract ( { years : 2 } ) ) ; /* Temporal.PlainDate 2024-01-31 <prototype>: Object { … } */ console . log ( nowTemporal ) ; /* Result (expanded): Temporal.PlainDate 2025-12-30 <prototype>: Object { … } */ Notice how none of these transformations required us to manually spin up any new objects, and that the value of the object referenced by nowTemporal remains unchanged? Unlike Date , the methods we use to interact with a Temporal object result in new Temporal objects, rather than requiring us to use them in the context of a new instance or to modify the instance we’re working with — which is how we’re able to chain the add and subtract methods together in nowTemporal.add({ months: 1, days: 1 }).subtract({ years: 2 }) . Sure, we’re still working with objects, and that means we’re working with mutable data structures that represent real-world values: Code language js Copy to clipboard const nowTemporal = Temporal . Now . plainDateISO ( ) ; nowTemporal . someProperty = true ; console . log ( nowTemporal ) ; /* Result (expanded): Temporal.PlainDate 2026-01-05 someProperty: true <prototype>: Object { … } …But the value represented by that Temporal object isn’t meant to be changed during the normal course of interacting with it — even though the object is still essentially mutable, we’re not stuck using that object in ways that could alter what it means in terms of real-world dates and times. I’ll take it. So, let’s revisit that janky little “today is X, tomorrow is Y” script we wrote using Date earlier. First, we’ll fix it by making sure we’re working with two discrete instances of Date rather than modifying the instance that represents today’s date: Code language js Copy to clipboard const today = new Date ( ) ; const addDay = theDate => { const tomorrow = new Date ( ) ; tomorrow . setDate ( theDate . getDate ( ) + 1 ) ; return tomorrow ; } ; console . log ( ` Tomorrow will be ${ addDay ( today ) . toLocaleDateString ( ) } . Today is ${ today . toLocaleDateString ( ) } . ` ) ; // Result: Tomorrow will be 1/1/2026. Today is 12/31/2025. Thanks, I hate it. Okay, fine. It gets the job done, just as it has since the day Date first bumbled its way onto the web. We’re not unwittingly altering the value of today since we’re spinning up a new instance of Date inside our addDay function — wordy, but it works, as it has for decades now. We add 1 to it, which we have to just kind of know means add one day. Then in our template literal we need to keep nudging JavaScript to give us the date in a format that doesn’t include the current time, as a string. It’s functional, but verbose. Now, let’s redo it using Temporal : Code language js Copy to clipboard const today = Temporal . Now . plainDateISO ( ) ; console . log ( ` Tomorrow will be ${ today . add ( { days : 1 } ) } . Today is ${ today } . ` ) ; // Result: Tomorrow will be 2026-01-01. Today is 2025-12-31. Now we’re talking. So much better . Leaner, meaner, and way less margin for error. We want today’s date without the time, and the object that results from invoking plainDateISO (and any new Temporal objects created from it) will retain that formatting without being coerced to a string. Formatting: check . We want to output a value that represents today’s date plus one day, and we want to do so in a way where we are unmistakably saying “add one day to it” with no parsing guesswork: check and check . Most importantly, we don’t want to run the risk of having our original today object altered unintentionally — because the result of calling the add method will always be a new Temporal object: check . Temporal is going to be a massive improvement over Date , and I only say “going to be” because it still isn’t quite ready for prime-time usage. The draft specification for the proposed Temporal object has reached stage three of the standardization process, meaning it is now officially “recommended for implementation” — not yet part of the standard that informs the ongoing development of JavaScript itself, but close enough that browsers can start tinkering with it. That means the results of that early experimentation may be used to further refine the specification, so nothing is set in stone just yet. Web standards are an iterative process, after all. That’s where you and I come in. Now that Temporal has landed in the latest versions of Chrome and Firefox — and others, soon — it’s time for us to get in there and kick the tires a little bit. We may not have had any say in Date , but we get to experiment with Temporal before the final implementations land. Soon, JavaScript will have sensible, modern date handling, and we’ll finally be able to cram Date way in the back of the junk drawer with the rubber bands, mismatched jar lids, mystery keys, and probably-half-empty AA batteries — still present, still an inexorable part of the web platform, but no longer our first, last, and only way of handling dates. And we only had to wait— well, hold on, let me just crunch the numbers real quick: Try it out const today = Temporal.Now.plainDateISO(); const jsShipped = Temporal.PlainDate.from( "1995-12-04" ); const sinceDate = today.since( jsShipped, { largestUnit: 'year' }); console.log( `${ sinceDate.years } years, ${ sinceDate.months } months, and ${ sinceDate.days } days.` ); Run Sure, the best time to replace Date would’ve been back in 1995, but hey: the second best time is Temporal.Now , right?

Report Abuse Sivaram Posted on Jan 8 Building a Production-Ready Prediction Market Smart Contract in Solidity: Complete Guide with Foundry # smartcontract # solidity # web3 # ethereum TL;DR I built an open-source, gas-optimized prediction market smart contract in Solidity using Foundry. It features pot-based binary markets, proportional payout distribution, admin resolution, and comprehensive security patterns. 95 tests, 98%+ coverage, deployable to Ethereum, Base, Polygon, Arbitrum, Optimism, and BSC. GitHub: https://github.com/SivaramPg/evm-simple-prediction-market-contract Table of Contents Introduction Architecture Overview Smart Contract Design Payout Formula Deep Dive Security Patterns Implemented Gas Optimization Techniques Testing with Foundry Multi-Chain Deployment Conclusion Introduction Prediction markets are fascinating DeFi primitives that allow users to bet on the outcome of future events. Unlike AMM-based prediction markets (like Polymarket's CLAMM), this implementation uses a simpler pot-based parimutuel system - perfect for learning smart contract development or bootstrapping your own prediction market protocol. What We're Building Binary prediction markets (YES/NO outcomes) Pot-based parimutuel betting (proportional payouts) ERC20 stablecoin integration (USDC, USDT, DAI) Admin-controlled resolution (oracle-free for simplicity) Multi-chain deployment (6 EVM chains) Tech Stack Solidity ^0.8.20 - Smart contract language Foundry - Development framework (forge, cast, anvil) OpenZeppelin patterns - Security best practices Slither/Mythril compatible - Static analysis ready Architecture Overview System Components ┌─────────────────────────────────────────────────────────────┐ │ PredictionMarket.sol │ ├─────────────────────────────────────────────────────────────┤ │ Config │ Market[] │ Positions │ │ - admin │ - id │ - yesBet │ │ - stablecoin │ - question │ - noBet │ │ - feeRecipient │ - resolutionTime │ - claimed │ │ - maxFeePercentage │ - state │ │ │ - paused │ - yesPool / noPool │ │ │ │ - winningOutcome │ │ │ │ - configSnapshot │ │ ├─────────────────────────────────────────────────────────────┤ │ Functions │ │ - createMarket() - placeBet() - claimWinnings() │ │ - resolveMarket() - cancelMarket() - claimMultiple() │ │ - pause/unpause() - updateConfig() │ └─────────────────────────────────────────────────────────────┘ Enter fullscreen mode Exit fullscreen mode State Machine Markets follow a strict state machine: ┌──────────┐ │ Active │ ←── createMarket() └────┬─────┘ │ │ (resolution time reached) ▼ ┌─────────────────────────────┐ │ │ ▼ ▼ ┌──────────┐ ┌───────────┐ │ Resolved │ │ Cancelled │ └──────────┘ └───────────┘ │ │ └──────────┬──────────────────┘ ▼ claimWinnings() Enter fullscreen mode Exit fullscreen mode Smart Contract Design Storage Layout Efficient storage packing is crucial for gas optimization: struct Config { address admin; // slot 0 (20 bytes) bool paused; // slot 0 (1 byte) - packed! address stablecoin; // slot 1 uint8 stablecoinDecimals;// slot 1 - packed! address feeRecipient; // slot 2 uint16 maxFeePercentage; // slot 2 - packed! uint256 marketCounter; // slot 3 } struct Market { uint256 id; string question; // dynamic, separate slot uint256 resolutionTime; MarketState state; // uint8 Outcome winningOutcome; // uint8 uint256 yesPool; uint256 noPool; uint256 creationFee; address creator; ConfigSnapshot configSnapshot; // frozen at creation } struct UserPosition { uint256 yesBet; uint256 noBet; bool claimed; } Enter fullscreen mode Exit fullscreen mode Key Design Decisions 1. Config Snapshot at Market Creation function createMarket(...) external returns (uint256) { // Snapshot config at creation time market.configSnapshot = ConfigSnapshot({ feeRecipient: config.feeRecipient, maxFeePercentage: config.maxFeePercentage }); } Enter fullscreen mode Exit fullscreen mode Why? If admin changes fee settings mid-market, existing markets retain their original terms. This prevents rug-pull scenarios where admins could change fees after users have committed funds. 2. No Opposition = Must Cancel function resolveMarket(uint256 marketId, Outcome outcome) external onlyAdmin { require(market.yesPool > 0 && market.noPool > 0, NoOpposition()); // ... } Enter fullscreen mode Exit fullscreen mode Why? If only one side has bets, there's no losing pool to distribute. The market must be cancelled with full refunds. 3. Manual Admin Resolution We chose manual resolution over oracles for simplicity. For production, consider integrating: Chainlink Functions for API-based resolution UMA Optimistic Oracle for dispute-based resolution Reality.eth for crowd-sourced resolution Payout Formula Deep Dive The Parimutuel Formula payout = user_bet + (user_bet / winning_pool) * losing_pool Enter fullscreen mode Exit fullscreen mode Or equivalently: payout = user_bet * (1 + losing_pool / winning_pool) payout = user_bet * total_pool / winning_pool Enter fullscreen mode Exit fullscreen mode Implementation function _calculatePayout( uint256 marketId, address user ) internal view returns (uint256) { Market storage market = markets[marketId]; UserPosition storage position = userPositions[marketId][user]; if (market.state == MarketState.Cancelled) { // Full refund on cancellation return position.yesBet + position.noBet; } // Resolved market uint256 winningPool; uint256 losingPool; uint256 userWinningBet; if (market.winningOutcome == Outcome.Yes) { winningPool = market.yesPool; losingPool = market.noPool; userWinningBet = position.yesBet; } else { winningPool = market.noPool; losingPool = market.yesPool; userWinningBet = position.noBet; } if (userWinningBet == 0) return 0; // payout = userBet + (userBet * losingPool) / winningPool uint256 winnings = (userWinningBet * losingPool) / winningPool; return userWinningBet + winnings; } Enter fullscreen mode Exit fullscreen mode Example Scenarios Scenario 1: Equal Pools YES pool: 100 USDC, NO pool: 100 USDC Alice bet 100 USDC on YES, YES wins Payout: 100 + (100 * 100) / 100 = 200 USDC (2x return) Scenario 2: Unequal Pools YES pool: 100 USDC, NO pool: 400 USDC Alice bet 100 USDC on YES, YES wins Payout: 100 + (100 * 400) / 100 = 500 USDC (5x return) Scenario 3: Multiple Winners YES pool: 200 USDC (Alice: 100, Bob: 100), NO pool: 100 USDC YES wins Alice: 100 + (100 * 100) / 200 = 150 USDC Bob: 100 + (100 * 100) / 200 = 150 USDC Security Patterns Implemented 1. Checks-Effects-Interactions (CEI) function claimWinnings(uint256 marketId) external { // CHECKS require(market.state != MarketState.Active, MarketNotFinalized()); require(!position.claimed, AlreadyClaimed()); require(position.yesBet > 0 || position.noBet > 0, NoPosition()); // EFFECTS position.claimed = true; uint256 payout = _calculatePayout(marketId, msg.sender); // INTERACTIONS if (payout > 0) { IERC20(config.stablecoin).transfer(msg.sender, payout); } } Enter fullscreen mode Exit fullscreen mode 2. Reentrancy Protection Although we follow CEI, we also use state flags: // The `claimed` flag is set BEFORE external call position.claimed = true; // EFFECT // ... IERC20(config.stablecoin).transfer(...); // INTERACTION Enter fullscreen mode Exit fullscreen mode 3. Integer Overflow Protection Solidity 0.8+ has built-in overflow checks, but we're explicit: // Safe accumulation market.yesPool += amount; // Reverts on overflow in 0.8+ Enter fullscreen mode Exit fullscreen mode 4. Access Control modifier onlyAdmin() { require(msg.sender == config.admin, NotAdmin()); _; } modifier whenNotPaused() { require(!config.paused, Paused()); _; } Enter fullscreen mode Exit fullscreen mode 5. Input Validation function createMarket( string calldata question, uint256 resolutionTime, uint256 fee ) external whenNotPaused returns (uint256) { require(bytes(question).length > 0, EmptyQuestion()); require(resolutionTime > block.timestamp, InvalidResolutionTime()); // ... } Enter fullscreen mode Exit fullscreen mode 6. Balance Checks Before Transfer function placeBet(...) external { require( IERC20(config.stablecoin).balanceOf(msg.sender) >= amount, InsufficientBalance() ); require( IERC20(config.stablecoin).allowance(msg.sender, address(this)) >= amount, InsufficientAllowance() ); // ... } Enter fullscreen mode Exit fullscreen mode Gas Optimization Techniques 1. Custom Errors (Solidity 0.8.4+) // Gas expensive require(condition, "This is an error message"); // Gas efficient (saves ~50 gas per error) error NotAdmin(); require(condition, NotAdmin()); Enter fullscreen mode Exit fullscreen mode 2. Calldata vs Memory // Use calldata for read-only dynamic parameters function createMarket( string calldata question, // calldata, not memory uint256 resolutionTime, uint256 fee ) external { ... } Enter fullscreen mode Exit fullscreen mode 3. Storage Packing struct Config { address admin; // 20 bytes bool paused; // 1 byte ─┐ uint8 decimals; // 1 byte ─┼─ packed into same slot uint16 maxFee; // 2 bytes ─┘ } Enter fullscreen mode Exit fullscreen mode 4. Unchecked Arithmetic (Where Safe) // When we know overflow is impossible unchecked { for (uint256 i = 0; i < marketIds.length; ++i) { // ++i is cheaper than i++ } } Enter fullscreen mode Exit fullscreen mode 5. Short-Circuit Evaluation // Cheaper check first require(market.state == MarketState.Active && block.timestamp < market.resolutionTime, MarketNotActive()); Enter fullscreen mode Exit fullscreen mode Testing with Foundry Test Structure test/ ├── BaseTest.sol # Common setup and helpers ├── unit/ │ ├── MarketCreation.t.sol │ ├── Betting.t.sol │ ├── Resolution.t.sol │ ├── Cancellation.t.sol │ ├── Claiming.t.sol │ ├── AccessControl.t.sol │ └── ViewFunctions.t.sol ├── integration/ │ └── MarketLifecycle.t.sol └── fuzz/ └── PayoutFuzz.t.sol Enter fullscreen mode Exit fullscreen mode Base Test Setup abstract contract BaseTest is Test { PredictionMarket public market;

Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content.

Report Abuse Polliog Posted on Jan 12 Why Cloudflare is Right to Stand Against Italy's Piracy Shield # cloud # dns # webdev # discuss Why Cloudflare is Right to Stand Against Italy's Piracy Shield In early January 2026, Italy's communications regulator AGCOM imposed a record-breaking €14.2 million fine on Cloudflare for refusing to implement DNS-level blocking through its popular 1.1.1.1 public resolver. While the fine represents just 1% of Cloudflare's global revenue, this case has profound implications for the future of internet infrastructure, digital rights, and the balance between copyright enforcement and an open web. As a developer and infrastructure professional, I believe Cloudflare's stance is not only justified but necessary. Here's why. Understanding the Piracy Shield System Italy's Piracy Shield platform, launched in February 2024, was designed to combat illegal streaming of live sports events, particularly Serie A football matches. The system requires internet service providers, VPN providers, and DNS resolvers to block access to reported domains and IP addresses within just 30 minutes of notification. On paper, this sounds reasonable. In practice, it's a technical and procedural nightmare that fundamentally misunderstands how the internet works. The Numbers Tell a Story Since its launch, Piracy Shield has blocked: Over 65,000 domain names Approximately 14,000 IP addresses But here's the problem: a significant portion of these blocks have caused collateral damage to legitimate services. The Technical Reality: Why DNS-Level Blocking Is Problematic 1. Shared Infrastructure Creates Collateral Damage The internet relies heavily on shared infrastructure. Multiple websites often share the same IP address through: Content Delivery Networks (CDNs) Shared hosting environments Virtual hosting configurations Cloud platforms When Piracy Shield blocks an IP address, it doesn't just block the pirate site—it can block dozens or even hundreds of legitimate services that happen to share that infrastructure. Research from the University of Twente found that Piracy Shield had inadvertently blocked hundreds of legitimate websites , including: Google Drive (blocked for several hours in October 2024) YouTube (same incident) Educational websites Charitable organizations Small business websites Payment platforms 2. The Scale of Cloudflare's Operations Cloudflare's 1.1.1.1 DNS resolver handles approximately 200 billion queries daily . It's used by millions of people worldwide who value privacy, speed, and reliability. Implementing Italy-specific filtering on this global infrastructure would: Increase latency for all users globally, not just in Italy Require constant monitoring and updates to blocklists Create a precedent for every country to demand similar filtering Transform a neutral infrastructure service into a content moderator 3. IP Address Recycling Hosting providers frequently recycle IP addresses, assigning them to new customers once freed. Under Piracy Shield's automated system: An IP used by a pirate site today might be assigned to a legitimate business tomorrow There's no clear mechanism for how long blocks should remain active The 24-hour unblocking window is insufficient for identifying and resolving false positives The Procedural Nightmare Beyond the technical issues, Piracy Shield suffers from severe procedural deficiencies: No Judicial Oversight The system operates as an automated platform where copyright holders (called "flaggers") can report domains and IPs directly to AGCOM, which then orders blocks within 30 minutes. There is: No judicial review before blocking No requirement to prove infringement No meaningful appeal process Complete lack of transparency about what gets blocked and why The 30-Minute Rule is Unrealistic Requiring ISPs and DNS providers to implement blocks within 30 minutes assumes: All reports are accurate (they're not) The internet operates with clear boundaries (it doesn't) Collateral damage is acceptable (it isn't) Technical implementation is trivial (it's not) This timeline makes it impossible to verify claims, assess collateral damage, or implement blocks carefully. Lack of Transparency For months, the list of blocked resources was completely secret. AGCOM denied FOIA requests repeatedly. Only through leaked data on GitHub could researchers verify the scope and accuracy of the blocks. This opacity makes it impossible for: Website owners to know if they're affected Users to understand why they can't access services Technical operators to plan around blocks Civil society to hold the system accountable The European Commission's Concerns In June 2025, the EU Commission sent a letter to Italy's Minister of Foreign Affairs expressing serious concerns that Piracy Shield may violate: The Digital Services Act (DSA) - particularly Article 8, which requires procedural safeguards when legal content is restricted The EU Charter of Fundamental Rights - specifically the rights to freedom of expression and information Even Italy's own AGCOM Commissioner Elisa Giomi publicly distanced herself from the system, stating that AGCOM "risks unintentionally limiting freedom of expression" and engages in censorship. Why This Matters for Developers As developers and infrastructure professionals, we should be deeply concerned about systems like Piracy Shield because: 1. It Sets a Dangerous Precedent If Italy succeeds in forcing Cloudflare to implement country-specific DNS filtering, other countries will follow. We'll end up with: Fragmented internet infrastructure Higher latency globally Increased operational complexity The "Splinternet" - a web divided by national borders 2. It Misunderstands DNS DNS is meant to be a neutral translation service - it converts domain names to IP addresses. It's not designed to be a content moderation layer. Using it as such: Undermines internet architecture Creates single points of failure Makes the internet less resilient Breaks the principle of end-to-end communication 3. It Doesn't Even Work Research shows that determined pirates simply: Migrate to new domains Switch to IPv6 addresses Use different hosting providers Employ VPNs and encrypted DNS Meanwhile, legitimate services suffer the consequences of overblocking. 4. It Threatens Smaller Services Cloudflare provides free cybersecurity services to millions of small websites. If forced to withdraw from Italy or implement filtering, these services would be most affected: Small businesses couldn't afford enterprise alternatives Independent creators would lose DDoS protection Educational resources would become vulnerable The democratization of web infrastructure would suffer The Better Alternative Copyright protection is important, and piracy is a real problem. But the solution isn't to break internet infrastructure. Better approaches include: Judicial review before blocking - ensure claims are verified before action Target the actual infringers - use legal mechanisms against operators, not infrastructure Improve content distribution - make legal content more accessible and affordable Implement safeguards - require proof that IPs are exclusively used for infringement Transparency and accountability - public blocklists with appeal mechanisms Reasonable timelines - allow time for verification and careful implementation Cloudflare's Response CEO Matthew Prince has been vocal in opposing this system, calling it: A scheme to "censor the Internet" Operated by "a shadowy cabal of European media elites" Lacking "judicial oversight, due process, appeal, or transparency" While the language is strong, the substance is accurate. Prince has indicated that if the fine stands, Cloudflare may: Discontinue free cybersecurity services for Italy-based users Remove all Cloudflare servers from Italy Terminate plans to build an Italian office These aren't idle threats—they're the logical consequence of a regulatory environment that makes it impossible to operate while maintaining service integrity. Conclusion: Standing for an Open Internet The Cloudflare vs. Italy dispute is about more than copyright enforcement. It's about whether we'll have a global, open internet or a fractured, censored one where every country can demand infrastructure providers become content police. Cloudflare is right to resist because: Technical feasibility : DNS-level blocking at global scale is technically harmful and creates unacceptable collateral damage Procedural fairness : No system should block content without judicial review and proper safeguards Proportionality : A fine exceeding double the revenue earned from an entire country is punitive, not corrective Precedent : Acquiescing would invite similar demands from every jurisdiction worldwide Internet architecture : DNS should remain neutral infrastructure, not a content moderation layer As developers, we build on the foundation of open protocols and neutral infrastructure. When regulators try to break that foundation in pursuit of short-term goals, we must stand against it—not because we support piracy, but because we understand that the cure is worse than the disease. The fight against piracy is legitimate. But it must be waged in ways that respect internet architecture, due process, and the rights of legitimate users and services. Italy's Piracy Shield fails on all counts. Cloudflare's resistance isn't about protecting pirates—it's about protecting the internet itself. What are your thoughts on this issue?

I completely agree that Cloudflare’s stance highlights how important it is to protect the integrity of internet infrastructure. Personally, I think solutions that combine legal oversight with technical precision, rather than blanket DNS blocking, could strike a better balance between copyright enforcement and user rights.

Report Abuse AMAAN SARFARAZ Posted on Jan 13 Building a LinkedIn Outreach Agent with LangGraph and ConnectSafely.ai # langgraph # ai # automation # typescript A production-style agentic workflow for LinkedIn outreach using LangGraph state machines and ConnectSafely.ai API This article walks through building a production-grade agentic workflow using LangGraph and ConnectSafely.ai for LinkedIn outreach automation. The goal: help job seekers identify relevant jobs, discover hiring managers, and perform controlled LinkedIn outreach— without browser automation, scraping, or UI hacking . Core Design Principles ✅ Explicit state transitions ✅ Deterministic tools ✅ Strict separation between reasoning and execution ✅ No prompt hacks or brittle automation System Architecture Overview This isn't a free-running autonomous loop. It's a graph-based agent where LangGraph controls execution flow and ConnectSafely.ai enforces safety boundaries. LangGraph State Machine ├─ Search jobs ├─ Resolve company details ├─ Find hiring managers ├─ Fetch LinkedIn profile data ├─ Check connection status └─ Send connection request ↓ ConnectSafely.ai API ↓ LinkedIn Platform Enter fullscreen mode Exit fullscreen mode LangGraph controls what happens next . ConnectSafely.ai controls what is allowed to happen . Why LangGraph Over Simple Agent Loops? LangGraph is used because this workflow is stateful and conditional . Each step: Consumes structured state Produces structured output Decides the next transition deterministically This approach: ✅ Avoids prompt-driven branching ✅ Makes execution traceable ✅ Enables debugging and replay ✅ Prevents infinite loops Project Structure ├── index.ts # Entry point ├── agents/ │ └── job-search-outreach-agent.ts # LangGraph state machine ├── tools/ # LinkedIn API wrappers │ ├── searchJobs.ts │ ├── getCompanyDetails.ts │ ├── searchHiringManagers.ts │ ├── fetchProfileDetails.ts │ ├── checkConnectionStatus.ts │ └── sendConnectionRequest.ts ├── cli/ # Interactive CLI └── .env # API keys Enter fullscreen mode Exit fullscreen mode Runtime Stack TypeScript for type safety Bun for fast startup and dependency management LangGraph for workflow orchestration ConnectSafely.ai for LinkedIn API access Entry Point // index.ts import { runCli } from " ./cli " ; runCli (); Enter fullscreen mode Exit fullscreen mode Simple, clean, and framework-agnostic. The Agent Definition The core logic lives in agents/job-search-outreach-agent.ts : import { StateGraph } from " @langchain/langgraph " ; const graph = new StateGraph < AgentState > () . addNode ( " searchJobs " , searchJobs ) . addNode ( " getCompanyDetails " , getCompanyDetails ) . addNode ( " searchHiringManagers " , searchHiringManagers ) . addNode ( " fetchProfileDetails " , fetchProfileDetails ) . addNode ( " checkConnectionStatus " , checkConnectionStatus ) . addNode ( " sendConnectionRequest " , sendConnectionRequest ) . addEdge ( " searchJobs " , " getCompanyDetails " ) . addEdge ( " getCompanyDetails " , " searchHiringManagers " ) . addEdge ( " searchHiringManagers " , " fetchProfileDetails " ) . addEdge ( " fetchProfileDetails " , " checkConnectionStatus " ) . addConditionalEdges ( " checkConnectionStatus " , routingLogic ); Enter fullscreen mode Exit fullscreen mode Each node is a pure function over state. No side effects, no hidden behavior. Tool Design: Deterministic by Construction All LinkedIn-facing logic is implemented as tools. Each tool: ✅ Has a single responsibility ✅ Performs one API call ✅ Returns structured data ✅ Never makes decisions This keeps the agent layer clean and testable. 1️⃣ Searching Jobs export async function searchJobs ( input : { keyword : string ; location : string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/search/jobs` , { headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` , " Content-Type " : " application/json " }, body : JSON . stringify ( input ) }); return response . json (); } Enter fullscreen mode Exit fullscreen mode The agent decides when to search. The tool only executes. 2️⃣ Fetching Company Details export async function getCompanyDetails ( input : { companyId : string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/search/companies/details` , { headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` } } ); return response . json (); } Enter fullscreen mode Exit fullscreen mode No scraping. No HTML parsing. Only structured responses. 3️⃣ Finding Hiring Managers export async function searchHiringManagers ( input : { companyId : string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/search/hiring-managers` , { headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` } } ); return response . json (); } Enter fullscreen mode Exit fullscreen mode The agent receives candidates directly—no guessing or scraping required. 4️⃣ Fetching Profile Details export async function fetchProfileDetails ( input : { profileId : string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/profile/details` , { headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` } } ); return response . json (); } Enter fullscreen mode Exit fullscreen mode This data is used for: ✅ Validation ✅ Personalization ✅ Rule-based decisions 5️⃣ Connection Safety Checks Before any outreach, the system verifies connection state: export async function checkConnectionStatus ( input : { profileId : string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/connections/status` , { headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` } } ); return response . json (); } Enter fullscreen mode Exit fullscreen mode This prevents: ❌ Duplicate requests ❌ Invalid actions ❌ Noisy automation LangGraph uses this output to decide the next edge. 6️⃣ Sending Connection Requests Only after passing all checks does the workflow reach execution: export async function sendConnectionRequest ( input : { profileId : string ; note ?: string ; }) { const response = await fetch ( ` ${ API_URL } /linkedin/connections/send` , { method : " POST " , headers : { Authorization : `Bearer ${ process . env . CONNECTSAFELY_API_KEY } ` , " Content-Type " : " application/json " }, body : JSON . stringify ( input ) } ); return response . json (); } Enter fullscreen mode Exit fullscreen mode The agent cannot bypass platform rules —those are enforced by ConnectSafely.ai. ConnectSafely.ai as the Execution Boundary This system does not : ❌ Run headless browsers ❌ Scrape LinkedIn pages ❌ Manage cookies or sessions ❌ Simulate human behavior Instead: ✅ All LinkedIn actions are API calls ✅ Authentication is key-based ✅ Rate limits and safety rules are enforced externally ✅ Platform complexity is isolated The agent stays clean and portable. CLI Interface The cli/ directory provides: # Interactive execution $ bun run start # Command routing $ bun run agent --job "Software Engineer" --location "San Francisco" # State visualization $ bun run agent --debug Enter fullscreen mode Exit fullscreen mode This makes the workflow usable without modifying code and helps with debugging graph transitions. State Management Example interface AgentState { // User inputs jobKeyword : string ; location : string ; // Job search results jobs : Job []; selectedJob ?: Job ; // Company context company ?: Company ; // Hiring managers hiringManagers : Profile []; selectedManager ?: Profile ; // Connection state connectionStatus ?: ConnectionStatus ; // Execution tracking currentStep : string ; errors : string []; } Enter fullscreen mode Exit fullscreen mode State flows through the graph explicitly—no hidden context. Conditional Routing Logic function routingLogic ( state : AgentState ): string { const { connectionStatus } = state ; if ( connectionStatus === " ALREADY_CONNECTED " ) { return " skipConnectionRequest " ; } if ( connectionStatus === " PENDING " ) { return " skipConnectionRequest " ; } if ( connectionStatus === " CAN_CONNECT " ) { return " sendConnectionRequest " ; } return " end " ; } Enter fullscreen mode Exit fullscreen mode Decision logic is explicit, testable, and debuggable . Why This Architecture Works This pattern scales because: ✅ Reasoning is explicit — no hidden prompt logic ✅ Execution is deterministic — same input = same path ✅ State is visible — full observability ✅ Platform risk is externalized — LinkedIn complexity isolated Ideal Use Cases 🎯 Recruiting workflows 🔍 Job discovery automation 📊 CRM enrichment ⚖️ Compliance-sensitive LinkedIn tooling 🤝 B2B outreach campaigns Key Takeaways LangGraph is ideal for multi-step, stateful agents Agents should orchestrate, not improvise LinkedIn automation belongs behind an API boundary Deterministic tools beat prompt-only logic Safety checks must be first-class nodes Get Started Prerequisites # Install Bun curl -fsSL https://bun.sh/install | bash # Clone the repository git clone https://github.com/ConnectSafelyAI/agentic-framework-examples/tree/main/job-seekers-reach-out-to-hiring-managers/agentic/langGraph # Install dependencies bun install # Set up environment variables cp .env.example .env # Add your ConnectSafely.ai API key Enter fullscreen mode Exit fullscreen mode Running the Agent # Interactive mode bun run start # Direct execution bun run agent --job "Product Manager" --location "Remote" Enter fullscreen mode Exit fullscreen mode Resources & Documentation Official Documentation ConnectSafely.ai Docs ConnectSafely.ai Dashboard LangGraph Documentation Support Email: support@connectsafely.ai Documentation: connectsafely.ai/docs Api Refrence: connectsafely.ai (API key management) Connect With Us LinkedIn YouTube Instagram Facebook X (Twitter) What's Next?

Report Abuse Mohammad-Idrees Posted on Jan 13 Thinking in First Principles: How to Question an Async Queue–Based Design # architecture # interview # learning # systemdesign Async queues are one of the most commonly suggested “solutions” in system design interviews. But many candidates jump straight to using queues without understanding: What problems they actually solve What new problems they introduce How to systematically discover those problems This post teaches a first-principles questioning process you can apply to any async queue design—without assuming prior knowledge. Why This Matters In interviews, interviewers are not evaluating whether you know Kafka, SQS, or RabbitMQ. They are evaluating whether you can: Reason about time Reason about failure Reason about order Reason about user experience Async queues change all four. What “First Principles” Means Here First principles means: We do not start with solutions We do not assume correctness We ask basic, unavoidable questions that every system must answer Async queues feel correct because they remove blocking—but correctness is not guaranteed by intuition. The Reference Mental Model (Abstract) We will reason about this abstract pattern , not a specific product: User → API → Storage → Queue → Worker → Storage Enter fullscreen mode Exit fullscreen mode No domain assumptions. This could be: Chat messages Emails Payments Notifications Image processing The questioning process stays the same. Step 1: The Root Question (Always Start Here) What is the system responsible for completing before it can respond? This is the most important question in system design. Why? Because it defines: Request boundaries Latency expectations Responsibility In an async queue design, the implicit answer is: “The request is complete once the work is enqueued.” This is different from synchronous designs, where the request completes after work finishes. So far, this seems good. Step 2: Introduce Time (What Happens Later?) Now ask: Which part of the work happens after the request is done? Answer: The worker processing This leads to an important realization: The system has split work across time Time separation is powerful—but it creates new questions. Step 3: Causality Question (Identity Across Time) Once work happens later, we must ask: How does the system know which output belongs to which input? This question always appears when time is decoupled. Typical answer: IDs in the job payload (request ID, entity ID) This introduces a new invariant: Each input must produce exactly one correct output Now we test whether the system can guarantee this. Step 4: Failure Question (The Queue Reality) Now ask the most important async-specific question: What happens if the worker crashes mid-processing? Realistic answers: The job is retried The work may run again The output may be produced twice This leads to a critical realization: Async queues are usually at-least-once , not exactly-once This is not a tooling issue. It is a fundamental property of distributed systems . Step 5: Duplication Question (Invariant Violation) Now ask: What happens if the same job is processed twice? Consequences: Duplicate outputs Duplicate side effects Conflicting state This violates the earlier invariant: “Exactly one output per input” At this point, we have discovered a correctness problem , not a performance problem. Step 6: Ordering Question (Time Without Synchrony) Now consider multiple inputs. Ask: What defines the order of processing? Important realization: Queue order ≠ business order Different workers process at different speeds Later inputs may finish first Now ask: Does correctness depend on order? If yes (and many systems do): Async queues alone are insufficient This problem emerges only when you question order explicitly. Step 7: Visibility Question (User Experience) Now switch perspectives. How does the user know the work is finished? Possible answers: Polling Guessing Timeouts Each answer reveals a problem: Polling wastes resources Guessing is unreliable Timeouts fail under load This violates a core system principle: Users should not wait blindly Case Study: A Simple Example (Problem-Agnostic) Imagine a system where users upload photos to be processed. Flow: User uploads photo API stores metadata Job is enqueued Worker processes photo Result is stored Now apply the questions: When does the upload request complete? → After enqueue What if the worker crashes? → Job retried What if it runs twice? → Two processed images What if two photos depend on order? → Order not guaranteed How does the user know processing is done? → Polling None of these issues are about images. They are about time, failure, identity, and visibility . What Async Queues Actually Trade Async queues solve one problem: They remove blocking from the request path But they introduce others: Solved Introduced Blocking Duplicate work Latency coupling Ordering ambiguity Resource exhaustion Completion uncertainty This is not bad. It just must be understood and handled . The One-Page Interview Checklist (Memorize This) For any async queue design , ask these five questions: What completes the request? What runs later? What happens if it runs twice? What defines order? How does the user observe completion? If you cannot answer all five clearly, the design is incomplete. Final Mental Model Async systems remove time coupling but destroy causality by default Your job as an engineer is not to “use queues” Your job is to restore correctness explicitly That is what interviewers are looking for.

Q: How do I set a cover image for my post? Q: Do I own the articles that I publish? Q: Can I cross-post something I've already written on my own blog or Medium? Q: Can I use profanity in my posts? Q: Why has my post been removed? Q: Will you put ads on my posts' pages? Explore the ins and outs of writing, editing, scheduling, and managing articles. The Editor The DEV editor is your primary tool for writing and sharing posts. With a Markdown -based syntax and flexible options for embedding content, the editor is one of the main ways DEV members express themselves. Drafting, scheduling, and publishing posts are all options; importing via RSS is also a feature that we provide. Learn how to use the DEV editor to create and format your articles effectively: Drafting and publishing a post: Click on " Write a Post " in the top right corner of the site. Follow the prompts to fill out the necessary inputs. Give your post a title, write the body content, add appropriate tags, and fill out any other optional fields. If you're not ready to share your article, just click "Save draft" in the bottom left. You can access your drafts from your user dashboard and return to editing your post whenever you wish. Once you're ready to share your post, click the "Publish" button in the bottom left. Note: if you are using the Basic Markdown editor you interface is more minimalistic, and you'll need to change published: false to published: true in the Front Matter of the post, then save to publish your post. Congratulations, your post should be published! You should see the article listed on your public profile. Note that you can access analytics for each post you've shared from your user dashboard by clicking on the ... beside the article title. Scheduling a post: To schedule a post, you may open a draft or start writing a new post. Once you've got your post set up, click on the hexagon icon in the bottom left-hand corner near the Publish button. See "Schedule Publication" and use the inputs to select a date and time for the post to go live. Note: this feature is set to your local time zone. Creating a Series DEV provides authors with the ability to link articles together in a series. A series has a title and an associated page to hold all the entries (e.g. Sloan's Inbox ). Most often this is done for articles that are thematically related or recurring weekly posts. We have a handy guide here that explains step-by-step how to create a series on DEV. Note: If you've written the first entry in a series and are wondering why the series title is not easily visible, it's because we don't actually display information about a post being part of a series until there is more than one entry in the series. Once you write your second entry in the series, the Table of Contents and title for the series should appear. Cross-posting Content DEV offers a variety of features for those who want to cross-post content from elsewhere on the web. We encourage folks to share articles from their personal and company blogs! Notably, we offer folks the ability to import content via RSS and set canonical links on any posts that are shared. Using the RSS Feed on DEV Community Configure RSS Feed: Navigate to extensions within the settings. Under "Publishing to DEV Community 👩💻👨💻 from RSS," enter your blog's RSS feed URL. You will see the option to "Mark the RSS source as canonical URL" or "Replace links with DEV Community links." Check the info below (Specifying a Canonical URL) to help you decide which option to select. Click "submit feed settings." Edit Post Drafts Before Publishing Go to your user dashboard. Click edit beside the post you want to post. Save each draft after making changes. Publish Post when ready. How to Specify a Canonical URL Members reposting content often worry about original posts becoming less discoverable in search engines and their website losing visibility as the newer publishing platform (e.g., DEV) might surpass the original blog. Fortunately, DEV allows authors to address these concerns. By inputting a canonical URL, contributors can ensure search engines understand the original source. This prevents any penalties for reposting, and search engine crawlers boost the ranking of the original article. Option 1 (RSS Import): Check the "Mark the RSS source as canonical URL by default" box upon import. Option 2 (Individual Posts): Identify your editor version in /settings/customization. Rich + Markdown Editor: Click the gear icon next to "Save draft" and enter the original post's URL in the "Canonical URL" field. Basic Markdown Editor: Add canonical_url: X to the post's front matter, specifying the original post's URL. Following these steps ensures proper attribution and maintains the visibility of your content. Helpful Resources Below you'll find various resources we recommend for better understanding DEV's writing policies and tools. DEV Editor guide A quick guide that provides you with technical tips for using the DEV Editor and our brand of Markdown. You can also find it by clicking the "?" page in the editor . Markdown Cheatsheet A handy cheatsheet for commonly-used Markdown formatting syntax. Best Practices for Writing on DEV A helpful series that offers both technical tips and general guidance for making the best-fit article for DEV. 🙌 Guidelines for Avoiding Plagiarism on DEV This resource offers guidance for how to avoid plagiarism. We take a strong stance against plagiarism on DEV; please don't hesitate to report any plagiarism to us. Guidelines for AI-assisted Articles on DEV These guidelines detail our requirements for properly labelling AI-assisted content on DEV. Please don't hesitate to report any content that is written with AI-assistance if it isn't following these guidelines. Common Questions Q: How do I set a canonical URL on my post? In the post editor, click the hexagon icon in the bottom left-hand corner beside "save draft" and you'll see an input box to designate a Canonical URL. Note: if you are using the Basic Markdown editor you must add a line for it inside the triple dashes (aka Front Matter), like so: --- title: published: false tags: canonical_url: <https://mycoolsite.com/my-post> --- Q: How do I set a cover image for my post? If using the Rich + Markdown editor, then click the "Add a cover image" button above the title of the post. If using the Basic Markdown editor, include cover_image: [url] in the front matter of your post. Note: you may change your editor type from your settings . Q: Do I own the articles that I publish? Yes, you own the rights to the content you create and post on dev.to and you have the full authority to post, edit, and remove your content as you see fit. Q: Can I cross-post something I've already written on my own blog or Medium? Absolutely, as long as you have the rights you need to do so! And if it's of high quality, we'll feature it. Q: Can I use profanity in my posts? We don't disallow profanity in general, but we do have an internal policy of not promoting posts that have profanity in the title, so you might want to keep that in mind. If your profanity is targeted at individuals or hateful, then it would cross the lines of what's acceptable via our Code of Conduct and we may take necessary action to remove you content. Q: Why has my post been removed? Your post is subject to removal at the discretion of the moderators if they believe it does not meet the requirements of our Code of Conduct . If you think we may have made a mistake, please email us at support@dev.to . Q: Will you put ads on my posts' pages? It's possible. We do allow organizations to purchase advertisements with DEV. However, if you would prefer that no ads be placed next to your posts, just navigate to Settings > Customization , scroll down to sponsors, and uncheck the box beside "Permit Nearby External Sponsors (When publishing)" Of course, we'd appreciate it if you keep those boxes checked as this is important to our business.

(optional) If you're using Highlight on the frontend for your application, make sure you've initialized it correctly and followed the fullstack mapping guide . 2 Install the relevant Highlight SDK(s). Install @highlight-run/node , @highlight-run/apollo with your package manager. npm install --save @highlight-run/node @highlight-run/apollo 3 Initialize the Highlight JS SDK. Initialize the Highlight JS SDK with your project ID. import { H } from '@highlight-run/node' H.init({ projectID: '<YOUR_PROJECT_ID>', serviceName: '<YOUR_SERVICE_NAME>', environment: 'production', }) 4 Add the Apollo Server integration. ApolloServerHighlightPlugin is an Apollo Server plugin to capture errors in your graphql handlers. import { ApolloServer } from '@apollo/server' import { ApolloServerHighlightPlugin } from '@highlight-run/apollo' // on legacy Apollo V3, use the following import // import { ApolloServerV3HighlightPlugin as ApolloServerHighlightPlugin } from '@highlight-run/apollo' // ... const server = new ApolloServer({ typeDefs, resolvers, plugins: [ ApolloServerHighlightPlugin({ projectID: '<YOUR_PROJECT_ID>', serviceName: 'my-apollo-app', serviceVersion: 'git-sha', environment: 'production' }), ], }) 5 Optionally, report manual errors in your app. If you need to report exceptions outside of a handler, use the Highlight SDK. const parsed = H.parseHeaders(request.headers) H.consumeError(error, parsed?.secureSessionId, parsed?.requestId) 6 Verify that your SDK is reporting errors. You'll want to throw an exception in one of your apollo handlers. Access the API handler and make sure the error shows up in Highlight . const server = new ApolloServer({ typeDefs, resolvers: { Query: { books: () => { throw new Error('a sample error!'); }, }, }, }); 7 Verify your backend logs are being recorded. Visit the highlight logs portal and check that backend logs are coming in. 8 Verify your backend traces are being recorded. Visit the highlight traces portal and check that backend traces are coming in. Highlight Integration in Javascript / Typescript AWS Lambda Node.JS Quick Start [object Object] | 2026-01-13T08:49:01 |
