Report Abuse Taqwah Posted on Dec 4, 2025 Color Theory in UI Design for Maximum Impact # uidesign Color is one of the most powerful tools in a UI designer's toolkit. It can influence a user's mood, guide their attention, and even affect their decision-making process. The right color palette can make an interface feel intuitive and delightful, while the wrong one can create confusion and frustration. Understanding how to use color effectively is not just about picking shades you like; it’s about applying the principles of color theory to create a cohesive and impactful user experience. This post will guide you through the fundamentals of color theory and how to apply them to your UI design projects. By the end, you'll have a clear understanding of how to choose colors that not only look good but also enhance usability and communicate your brand's message. Why Color Matters in UI Design Color does more than just make an interface visually appealing. It plays a critical role in usability and user experience by: Establishing Visual Hierarchy: Strategic color usage can draw attention to important elements like call-to-action (CTA) buttons, links, and notifications. By using brighter or contrasting colors for key actions, you can guide users through the interface naturally. Communicating Brand Identity: Colors evoke emotions and associations. A well-chosen palette reinforces a brand's personality, whether it's the trustworthy blue of a financial app or the energetic orange of a fitness tracker. Improving Readability and Accessibility: The contrast between text and its background is crucial for readability. Following accessibility guidelines, like the Web Content Accessibility Guidelines (WCAG), ensures your design is usable for people with visual impairments, including color blindness. Providing User Feedback: Colors can instantly communicate the status of an action. For example, a green checkmark indicates success, a red error message signals a problem, and a disabled button is often grayed out. Understanding the Color Wheel The foundation of color theory is the color wheel, which organizes colors to show the relationships between them. It’s an essential tool for creating harmonious palettes. Primary Colors Primary colors are the building blocks of all other colors. They cannot be created by mixing other colors. The primary colors in the traditional (RYB) model are Red, Yellow, and Blue. In the digital (RGB) model used for screens, there are Red, Green, and Blue. Secondary Colors Secondary colors are created by mixing two primary colors. Red + Yellow = Orange Yellow + Blue = Green Blue + Red = Violet Tertiary Colors Tertiary colors are made by mixing a primary color with an adjacent secondary color. These include shades like red-orange, yellow-green, and blue-violet. They offer a more nuanced and sophisticated palette. Creating Harmony with Color Schemes A color scheme is the selection of colors used in a design. Using established harmonies from the color wheel can help you create a balanced and visually pleasing palette. Monochromatic: This scheme uses variations—tints, tones, and shades—of a single color. It creates a clean, elegant, and unified look. For example, a palette might range from a light blue to a dark navy. Analogous: This approach uses colors that are next to each other on the color wheel, such as blue, blue-green, and green. Analogous schemes are harmonious and often found in nature, creating a serene and comfortable design. Complementary: This scheme involves two colors that are directly opposite each other on the color wheel, like red and green or blue and orange. This high-contrast combination is vibrant and attention-grabbing, making it great for highlighting key elements. Triadic: A triadic scheme uses three colors that are evenly spaced around the color wheel, forming a triangle. For example, red, yellow, and blue. This scheme offers strong visual contrast while retaining balance and is often quite dynamic. The Psychological Impact of Color Different colors can evoke specific emotions and influence user behavior. While these associations can vary across cultures, some general patterns are widely recognized in Western contexts. Red: Evokes passion, excitement, and urgency. It's often used for CTAs, sales, or error messages. Blue: Conveys trust, security, and professionalism. It's a popular choice for corporate brands, financial institutions, and tech companies. Green: **Associated with nature, growth, and success. It's often used for "success" notifications, environmental brands, and health-related apps. **Yellow: Represents optimism, warmth, and clarity. It can be used to grab attention, but it should be used sparingly, as it can cause eye fatigue. Orange: A friendly and energetic color that combines the warmth of red and the cheerfulness of yellow. It's great for CTAs that encourage action. Purple: Often linked to creativity, luxury, and wisdom. It can give a product a sophisticated or imaginative feel. Black: Signifies elegance, power, and modernity. It's frequently used in luxury branding and for creating a sleek, minimalist aesthetic. White: Represents simplicity, cleanliness, and minimalism. It's often used as a background color to create a sense of space and focus attention on other elements. Applying Color Theory in UI: Best Practices Knowing the theory is one thing; applying it effectively is another. Here are some best practices to follow. Follow the 60-30-10 Rule: This is a classic interior design principle that works just as well for UI. Allocate 60% of your color to a dominant hue, 30% to a secondary color, and 10% to an accent color. This creates a balanced and visually appealing design that is easy on the eyes. Design for Accessibility: Ensure your color choices provide sufficient contrast for readability. Tools like the WebAIM Contrast Checker can help you test your color pairs against WCAG standards. Consider Cultural Context: Color meanings can differ significantly across cultures. Research your target audience to ensure your color choices resonate positively and avoid unintended connotations. Test Your Palette: Apply your color palette to your wireframes and prototypes to see how it works in practice. Test it on different devices and in various lighting conditions. Tools for Choosing Color Palettes You don't have to start from scratch. Several excellent tools can help you generate and test color palettes. Adobe Color: A powerful tool that allows you to create palettes based on color harmonies, extract colors from images, and explore thousands of themes created by others. Coolors: A fast and easy-to-use color scheme generator. You can generate random palettes, adjust them, and save them for later. Color Hunt: A curated collection of beautiful color palettes. It's a great source of inspiration when you're starting a new project. Paletton: A more advanced tool for designers who want fine-tuned control over their color harmonies. Common Mistakes to Avoid Even with the best intentions, it's easy to make mistakes. Watch out for these common pitfalls: Using Too Many Colors: A cluttered palette can overwhelm users and make your interface look unprofessional. Stick to a limited number of colors. Ignoring Accessibility: Low-contrast text is one of the most common accessibility issues. Always prioritize readability over aesthetics. Relying Purely on Color: Don't use color as the only way to convey information. Use icons, text labels, or other visual cues to support users who may have difficulty distinguishing colors. From Theory to Practice Mastering color theory is an ongoing journey for any UI designer. It’s a blend of science, art, and psychology. By understanding the fundamentals of the color wheel, applying established harmonies, and considering the psychological impact of your choices, you can create interfaces that are not only beautiful but also effective and inclusive. Start experimenting with these principles in your next project, and watch how a thoughtful color strategy can transform your design.

Report Abuse Yusuf Adeyemo for AWS Community Builders Posted on Oct 20, 2025 How to Speed Up AWS CodeBuild Docker Builds by 25% or more Using ECR as a Remote Cache # aws # docker # cache Have you ever sat there waiting for your CodeBuild project to rebuild your entire Docker image... again? Even though you only changed a single line of code? Yeah, me too. And it's frustrating. Today, I'm going to show you how I reduced our Docker build times from ~6 minutes down to ~2 minutes by implementing Amazon ECR as a persistent cache backend. This is based on an official AWS blog post , but I'll walk you through the practical implementation. The Problem: Why Your Builds Are Slow Here's the thing about AWS CodeBuild: every build runs in a completely fresh, isolated environment . That means: No build artifacts carry over between builds Every build starts from scratch CodeBuild's "local cache" is temporary and unreliable (works on a "best-effort" basis) If your builds happen at different times throughout the day, the local cache probably isn't helping you So even if you only changed one line in your code, CodeBuild rebuilds every single Docker layer. Every. Single. Time. The Solution: ECR Registry Cache Backend The solution is surprisingly elegant: store your Docker layer cache persistently in Amazon ECR (Elastic Container Registry). Think of it as a separate "cache image" that lives alongside your actual application image. Here's how it works: First Build : Build from scratch, then export the cache to ECR as a separate image Subsequent Builds : Import the cache from ECR, rebuild only what changed, export the updated cache back The beauty? Your cache is always available, no matter when you trigger a build. What You'll Need Before we start, make sure you have: An existing AWS CodeBuild project that builds Docker images An ECR repository where your images are stored IAM permissions for your CodeBuild role to push/pull from ECR (if you can already push images, you're good!) About 10 minutes to implement this Step-by-Step Implementation Step 1: Understanding Your Current Buildspec Your current buildspec probably looks something like this: version : 0.2 phases : install : commands : - aws ecr get-login-password | docker login ... build : commands : - docker build -t myapp:latest . - docker tag myapp:latest $ECR_REPO:latest post_build : commands : - docker push $ECR_REPO:latest Enter fullscreen mode Exit fullscreen mode This is the "basic" approach. Every build starts from zero. [📸 IMAGE SUGGESTION: Split screen showing "Basic Build" vs "Cached Build" with layer rebuilding visualization] Step 2: Add Cache Tag Variable First, let's define a separate tag for our cache image. In your install phase, add: install : commands : - CACHE_TAG=dev-cache # or prod-cache, staging-cache, etc. - IMAGE_TAG=latest # your actual app image tag Enter fullscreen mode Exit fullscreen mode This creates a separate cache image (e.g., myapp:dev-cache ) that's distinct from your application image ( myapp:latest ). Step 3: Create the Buildx Builder Here's the key part: Docker's default builder doesn't support registry cache backends. We need to create a new builder using buildx with the containerd driver. Add this to your install phase: install : commands : # ... your existing commands ... - docker buildx create --name containerd --driver=docker-container --driver-opt default-load=true --use || docker buildx use containerd Enter fullscreen mode Exit fullscreen mode What's happening here? docker buildx create : Creates a new builder instance --driver=docker-container : Uses containerd (required for registry cache) --driver-opt default-load=true : Loads built images into local Docker (important!) || docker buildx use containerd : If the builder already exists, just switch to it Step 4: Replace Your Docker Build Command Now replace your regular docker build command with the new buildx version: build : commands : - | docker buildx build \ --builder=containerd \ --cache-from type=registry,ref=$ECR_REPO:$CACHE_TAG \ --cache-to type=registry,ref=$ECR_REPO:$CACHE_TAG,mode=max,image-manifest=true \ -t $ECR_REPO:$IMAGE_TAG \ --load \ . Enter fullscreen mode Exit fullscreen mode Let me break down what each flag does: --builder=containerd : Use the builder we just created --cache-from type=registry,ref=$ECR_REPO:$CACHE_TAG : Import cache from ECR --cache-to type=registry,ref=$ECR_REPO:$CACHE_TAG,mode=max,image-manifest=true : Export cache back to ECR mode=max : Export all layers (recommended for best caching) image-manifest=true : Required for ECR storage -t $ECR_REPO:$IMAGE_TAG : Tag your final image as usual --load : Load the built image into local Docker (so you can run it in post_build) . : Your Dockerfile location Step 5: Complete Example Buildspec Here's what a complete, production-ready buildspec looks like: version : 0.2 phases : install : commands : - echo Logging in to Amazon ECR - aws ecr get-login-password --region $AWS_REGION | docker login --username AWS --password-stdin $AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com - CACHE_TAG=dev-cache - IMAGE_TAG=latest - ECR_REPO=$AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/myapp - docker buildx create --name containerd --driver=docker-container --driver-opt default-load=true --use || docker buildx use containerd build : commands : - echo Build started on `date` - | docker buildx build \ --builder=containerd \ --cache-from type=registry,ref=$ECR_REPO:$CACHE_TAG \ --cache-to type=registry,ref=$ECR_REPO:$CACHE_TAG,mode=max,image-manifest=true \ -t $ECR_REPO:$IMAGE_TAG \ --load \ . - docker tag $ECR_REPO:$IMAGE_TAG $ECR_REPO:latest post_build : commands : - echo Build completed on `date` - docker push $ECR_REPO:$IMAGE_TAG - docker push $ECR_REPO:latest artifacts : files : - imageDefinitions.json Enter fullscreen mode Exit fullscreen mode Step 6: Update Your CodeBuild Project You can update your buildspec in two ways: Option 1: If your buildspec is in your repo Just commit the changes and push. CodeBuild will pick up the new buildspec automatically. Option 2: If your buildspec is defined in CodeBuild Use the AWS CLI: aws codebuild update-project --name your-project-name --cli-input-json file://buildspec.json Enter fullscreen mode Exit fullscreen mode Or update it through the AWS Console: CodeBuild → Your Project → Edit → Buildspec What to Expect: First Build vs Subsequent Builds First Build (The Investment) Your first build after implementing this will actually take slightly longer (maybe 30-60 seconds more). Don't panic! This is normal. Here's what's happening: Creating the buildx builder (~5-10 seconds) Attempting to import cache (fails - no cache exists yet) Building all layers from scratch Exporting the cache to ECR (new step, adds ~20-40 seconds) You'll see messages like: => importing cache manifest from $ECR_REPO:dev-cache => error: not found Enter fullscreen mode Exit fullscreen mode This is expected! The cache doesn't exist yet. Subsequent Builds (The Payoff) This is where the magic happens. Your next builds will: Successfully import the cache from ECR Identify which layers haven't changed Reuse cached layers (fast!) Rebuild only the changed layers Export the updated cache Expected time savings: Before : 6-7 minutes (full rebuild every time) After : 5-5.5 minutes (25-30% faster!) Savings : 1-2 minutes per build If you're doing 10 builds a day, that's 10-20 minutes saved daily . Over a month? That's 5-10 hours of compute time and costs saved. Verifying It's Working After your first build completes, check your ECR repository. You should now see two image tags : [📸 IMAGE SUGGESTION: ECR Console screenshot showing two images: "myapp:latest" and "myapp:dev-cache"] Your application image (e.g., latest ) Your cache image (e.g., dev-cache ) The cache image will be roughly the same size as your application image - this is normal! It's storing all the layer information. Troubleshooting Common Issues Issue 1: "buildx: command not found" Solution : Update your CodeBuild image to a newer version. Use aws/codebuild/standard:7.0 or later (or the ARM equivalent). Issue 2: Cache Import Keeps Failing Solution : Check your IAM permissions. Your CodeBuild role needs: ecr:BatchGetImage ecr:GetDownloadUrlForLayer ecr:BatchCheckLayerAvailability ecr:PutImage ecr:InitiateLayerUpload ecr:UploadLayerPart ecr:CompleteLayerUpload Issue 3: Build Hangs at "exporting cache" Solution : Make sure privilegedMode: true is enabled in your CodeBuild environment settings. This is required for Docker-in-Docker operations. Advanced: Multi-Environment Setup If you have multiple environments (dev, staging, prod), use different cache tags for each: - CACHE_TAG=${ENVIRONMENT}-cache # Results in: dev-cache, staging-cache, prod-cache Enter fullscreen mode Exit fullscreen mode This way: Dev builds don't invalidate staging cache Each environment maintains its own optimized cache You can still share a base cache if needed Cost Considerations Storage Cost : You're now storing an additional cache image in ECR. At roughly the same size as your app image, this might add $0.10-0.50/month per repository depending on image size. Compute Savings : Faster builds = less compute time. If you're saving 1-2 minutes per build and doing 10 builds/day, that's roughly 10-20 fewer compute hours per month. At ~$0.005/minute for BUILD_GENERAL1_SMALL , you could save $3-6/month. Net Result : Typically a small net savings, plus the huge developer experience win of faster feedback loops. Conclusion By implementing ECR as a remote cache backend for your CodeBuild Docker builds, you get: ✅ 25-30% faster build times ✅ Persistent, reliable caching across all builds ✅ Better layer reuse with intelligent cache management ✅ Minimal code changes (just updating your buildspec) ✅ Cost savings from reduced compute time The implementation is straightforward, and the benefits are immediate (after the first build). Give it a try on your next project!

These protocols play a pivotal role in shaping how emails are sent, received, and managed. In this article, we embark on an in-depth journey to explore IMAP vs. POP3, unraveling their unique usages, commonalities, and distinctions. Understanding SMTP (Simple Mail Transfer Protocol) What Is SMTP? SMTP, or Simple Mail Transfer Protocol, is the foundation of email communication, with a primary focus on sending emails. It plays a pivotal role in email delivery, making it a crucial component in the digital communication ecosystem. SMTP Servers: Relays and Receivers SMTP servers come in two primary types: Relays and Receivers. Relays : These servers accept emails from users and route them to the appropriate recipients. Receivers : Their primary function is to deliver emails to the recipient's mailbox after accepting them from Relay servers. How Does SMTP Work? SMTP follows a streamlined workflow: Client-Server Connection : The SMTP client establishes a connection with the SMTP server. Email Transfer : The email is transferred through this connection. Connection Termination: The client and server terminate the connection. Commands and Responses: SMTP clients use text-based commands, such as HELLO, MAIL FROM, EHLO, and RCPT, to communicate with the SMTP server. The server responds with numeric codes like 220, 250, and 354. Advantages of SMTP Dependability : SMTP ensures the reliable delivery of outgoing email messages. Persistent Delivery : If a message fails to deliver, SMTP will make repeated attempts until successful. User-Friendly : SMTP is relatively easy to use. Clear Failure Reporting : In case of failure, SMTP provides clear explanations. Disadvantages of SMTP Firewall Issues : Firewalls often block ports used by SMTP. Limited Security : SMTP's security features may be insufficient. Size Limitations : SMTP servers may reject excessively large email messages. Server Constraints : Server limitations can impact SMTP functionality. Understanding IMAP (Internet Message Access Protocol) What Is IMAP? IMAP versus POP3 is a common comparison among technical professionals. IMAP, or Internet Message Access Protocol, is a protocol primarily used for receiving emails from a server. It is known for its unique capability to keep emails on the server, allowing access from multiple locations simultaneously. How Does IMAP Work? IMAP operates with a distinct approach: When using IMAP, the client connects to the server to check for new messages and saves them in the cache as temporary files. This feature is a critical difference between IMAP and POP3. Initially, only email metadata, such as date, sender, and subject, is downloaded from the server. This sets IMAP apart from POP3. Full content is downloaded only when the recipient opens the message, which demonstrates the difference between IMAP and POP3. Changes, such as email modifications, deletions, or status updates, are immediately reflected on the server. This real-time synchronization enables consistent email status across multiple devices, an advantage that IMAP has over POP3. Advantages of IMAP Resilience : IMAP is unaffected by local machine failures, as emails are stored on the server. Multi-Device Access : It allows simultaneous access from multiple devices, which is an important consideration when deciding between IMAP vs. POP3. Efficient Searching : IMAP supports efficient, keyboard-based email searching. Minimal Local Storage: Local storage usage is minimal. Disadvantages of IMAP Synchronization Overhead : Accessing emails may be slower compared to POP3 due to folder synchronization. Internet Dependency: IMAP requires an active internet connection for email access. Storage Costs : Frequent email use may necessitate larger mailbox storage, potentially incurring higher costs. Understanding POP3 (Post Office Protocol 3) What Is POP3? POP3 or IMAP4 is a common choice that technical professionals need to make. POP3, or Post Office Protocol version 3, is a user-friendly method for accessing mailboxes. It's favored for its ability to allow users to read emails even when offline, making it a practical choice in situations with unstable internet connections. How Does POP3 Work? POP3 follows a straightforward process: User Authentication : The client authenticates itself with the POP3 server using a username and password. Message Retrieval: The client issues text-based commands to retrieve all email messages, which is a key differentiator between POP3 vs. IMAP. Local Storage : Downloaded messages are saved on the user's local system, making POP3 a preferred choice for those who need offline access. Server Deletion : The server copies are deleted. Disconnect : The client disconnects from the server. Advantages of POP3 User-Friendly : POP3 is popular, simple to set up, and easy to use. Offline Access : Emails are downloaded to the user's computer, enabling offline reading, a significant benefit of POP3 vs. IMAP. Quick Attachment Access : Attachments are quickly accessible since they are already downloaded. Minimal Server Storage : POP3 uses less server storage as emails are stored on the local machine. Disadvantages of POP3 Security Concerns : Email attachments may contain viruses, posing a risk to the user's computer, a consideration when choosing POP3 or IMAP. Limited Portability : It can be challenging to export local mail folders to another email client or machine, which is a point to think about when deciding POP3 vs. IMAP. Risk of Corruption : Email folders can become corrupted, potentially resulting in data loss, a risk associated with POP3. Differences Between SMTP, IMAP, and POP3 Aspect SMTP IMAP POP3 Purpose Sending emails Retrieving emails from a server Retrieving emails from a server Operation Type Push protocol - Pull protocol Scope Client to server communication Server to client communication Server to client communication Email Organization Client storage Server storage Client storage Downloading Approach - Download message headers first Download all emails simultaneously Offline Access - Email content is not fully downloaded until opened Email content is downloaded, allowing offline access Email Management - Real-time synchronization of changes across multiple devices Downloaded and deleted from the server Security Considerations Limited; Encryption and authentication options may vary Supports secure connections; Offers encryption and strong authentication Limited; Limited encryption and authentication options Suitability for Mobile Used for sending from a mobile device Ideal for mobile email access Ideal for mobile email access Storage Location Local device storage Server-based storage Local device storage Additional Considerations May not store emails on the server Multiple devices can access emails simultaneously Best for single-device use, storage limitations What factors to consider while choosing in between SMTP, IMAP and POP3? The thing to understand is that all these are not same. Let's see what factors can let you choose your preferred email protocol. Factor SMTP IMAP POP3 Email Sending vs. Receiving Sending Receiving Receiving Real-Time Synchronization No Yes No Offline Access No No Yes Storage and Server Space Emails stored on server Emails stored on server Emails downloaded to local device Internet Connection Stability Requires stable internet Requires stable internet Offline access Security Considerations Secure sending, limited storage Secure, emails on server, encryption Secure, emails on local device Still didn't understood SMTP vs IMAP vs POP3? We have a food-analogy to help you understand Love food? Let's use it to help you understand this concept! SMTP - Placing an Order Imagine using a food delivery service like ordering pizza. When you place an order, you act as an SMTP client. Here's how it works: You decide what type of pizza you want and place your order (acting as an SMTP client sending an email). The restaurant receives your order (SMTP server), processes it, and prepares your pizza. The delivery person takes the pizza to your doorstep (email is delivered to the recipient). Key Points: SMTP is like placing an order for food, focusing on sending your request (email) to the restaurant (server). The client (you) initiates the order and sends it to the server (restaurant) for delivery. IMAP - Buffet Access Now, consider IMAP as visiting an all-you-can-eat buffet. At a buffet, you have a vast array of dishes available. You can select what you want, and it's served to you. All the food stays at the buffet until you choose to take some. Everyone in your group can access the same buffet and pick what they like. Key Points: IMAP is like an all-you-can-eat buffet where you can access a wide range of dishes (emails). The food (emails) stays at the buffet (server) until you choose to access it, and multiple people (devices) can serve themselves from the same selection. POP3 - Takeout Orders In the case of POP3, think of it as placing a takeout order at a restaurant. You call the restaurant, specify your order, and then go to the restaurant to collect your food. The food is removed from the restaurant's kitchen and handed over to you. Key Points: POP3 is akin to placing a takeout order at a restaurant. Once you collect your food (download your emails), it's removed from the restaurant's kitchen (server) and given to you to consume locally. Applying the Food Delivery Analogy to Email Protocols SMTP is like placing an order for food, where you initiate the request (email) and send it to the restaurant (server) for delivery. IMAP is similar to an all-you-can-eat buffet where you can access a variety of dishes (emails) that stay at the buffet (server) until you choose to take them. Multiple people (devices) can access the same selection. POP3 is like placing a takeout order at a restaurant, where you collect your food (emails) from the restaurant (server) to consume locally. Hoping your love for food, will help you understand this concept about POP3 vs IMAP vs SMTP :) Conclusion In this comprehensive technical comparison, we introduced SMTP, IMAP, and POP3, covering their functionalities and contrasting features. SMTP excels in sending emails, while IMAP and POP3 are specialized in receiving. Your choice among these protocols depends on your specific use case and requirements. Frequently Asked Questions Is IMAP the same as SMTP? No, IMAP and SMTP serve different purposes. SMTP is used to send emails, while IMAP is used to manage and retrieve emails from a server. Are IMAP and SMTP passwords the same? When setting up an email account, you typically use the same password for both IMAP and SMTP. How do I find my SMTP and IMAP settings? The method to find your SMTP and IMAP settings varies depending on your email service provider and the email client you use. For example, in Outlook, you can access these settings in the POP and IMAP settings on Outlook.com. Should I use POP3 or IMAP? Your choice between POP3 and IMAP depends on factors such as the number of devices you use, your internet connection stability, and your email usage patterns. POP3 is suitable for single-device use and offline access, while IMAP is ideal for multi-device synchronization and real-time email management. Consider your specific needs when making a choice.

These capabilities are critical when you need to implement queue and stack data structures that operate efficiently even under heavy workloads. In this tutorial, you’ll learn how deque works, when to use it over a list , and how to apply it in real code. By the end of this tutorial, you’ll understand that: deque internally uses a doubly linked list , so end operations are O(1) while random indexing is O(n) . You can build a FIFO queue with .append() and .popleft() , and a LIFO stack with .append() and .pop() . deque supports indexing but doesn’t support slicing . Passing a value to maxlen creates a bounded deque that drops items from the opposite end when full. In CPython, .append() , .appendleft() , .pop() , .popleft() , and len() are thread-safe for multithreaded use. Up next, you’ll get started with deque , benchmark it against list , and explore how it shines in real-world use cases, such as queues, stacks, history buffers, and thread-safe producer-consumer setups. Get Your Code: Click here to download the free sample code that shows you how to implement efficient queues and stacks with Python’s deque.

You’ll receive a score upon completion to help you track your learning progress: Interactive Quiz Python's deque: Implement Efficient Queues and Stacks Use Python's deque for fast queues and stacks. Refresh end operations, maxlen rollover, indexing limits, and thread-safe methods. Get Started With Python’s deque Appending to and popping from the right end of a Python list are efficient operations most of the time. Using the Big O notation for time complexity , these operations are O(1) . However, when Python needs to reallocate memory to grow the underlying list to accept new items, these operations slow down and can become O ( n ). In contrast, appending and popping items from the left end of a Python list are always inefficient and have O ( n ) time complexity. Because Python lists provide both operations with the .append() and .pop() methods , you can use them as stacks and queues . However, the performance issues you saw before can significantly impact the overall performance of your applications. Python’s deque was the first data type added to the collections module back in Python 2.4 . This data type was specially designed to overcome the efficiency problems of .append() and .pop() in Python lists. A deque is a sequence -like data structure designed as a generalization of stacks and queues . It supports memory-efficient and fast append and pop operations on both ends. Note: The word deque is pronounced as “deck.” The name stands for d ouble- e nded que ue . Append and pop operations on both ends of a deque object are stable and equally efficient because deques are implemented as a doubly linked list . Additionally, append and pop operations on deques are thread-safe and memory-efficient. These features make deques particularly useful for creating custom stacks and queues in Python. Deques are also a good choice when you need to keep a list of recently seen items, as you can restrict the maximum length of your deque. By setting a maximum length, once a deque is full, it automatically discards items from one end when you append new items to the opposite end. Here’s a summary of the main features of deque : Stores items of any data type Is a mutable data type Supports membership operations with the in operator Supports indexing , like in a_deque[i] Doesn’t support slicing , like in a_deque[0:2] Supports built-in functions that operate on sequences and iterables , such as len() , sorted() , reversed() , and more Doesn’t support in-place sorting Supports normal and reverse iteration Supports pickling with pickle Supports fast, memory-efficient, and thread-safe pop and append operations on both ends To create deques, you just need to import deque from collections and call it with an optional iterable as an argument : Python >>> from collections import deque >>> # Create an empty deque >>> deque () deque([]) >>> # Use different iterables to create deques >>> deque (( 1 , 2 , 3 , 4 )) deque([1, 2, 3, 4]) >>> deque ([ 1 , 2 , 3 , 4 ]) deque([1, 2, 3, 4]) >>> deque ( range ( 1 , 5 )) deque([1, 2, 3, 4]) >>> deque ( "abcd" ) deque(['a', 'b', 'c', 'd']) >>> numbers = { "one" : 1 , "two" : 2 , "three" : 3 , "four" : 4 } >>> deque ( numbers . keys ()) deque(['one', 'two', 'three', 'four']) >>> deque ( numbers . values ()) deque([1, 2, 3, 4]) >>> deque ( numbers . items ()) deque([('one', 1), ('two', 2), ('three', 3), ('four', 4)]) If you instantiate deque without providing an iterable as an argument, then you get an empty deque. If you provide an iterable , then deque initializes the new instance with data from it. The initialization goes from left to right using deque.append() . The deque initializer takes the following two optional arguments : iterable holds an iterable that provides the initialization data. maxlen holds an integer number that specifies the maximum length of the deque. As mentioned previously, if you don’t supply an iterable , then you get an empty deque. If you provide a value to maxlen , then your deque will only store up to maxlen items. Finally, you can also use unordered iterables, such as sets , to initialize your deques. In those cases, you won’t have a predefined order for the items in the final deque.

Enums Can Come in Useful Python doesn’t have constants. You probably learnt this early on when learning Python. Unlike many other programming languages, you can’t define a constant in Python. All variables are variable! “Ah, but there are immutable types.” Sure, you can have an object that doesn’t change throughout its lifetime. But you can’t have a reference to it that’s guaranteed not to change. The identifier (variable name) you use to refer to this immutable type can easily switch to refer to something else. “How about using all caps for the identifier. Doesn’t that make it a constant?” No, it doesn’t. That’s just a convention you use to show your intent as a programmer that an identifier refers to a value that shouldn’t change. But nothing prevents that value from changing. Here’s an all-uppercase identifier that refers to an immutable object: All code blocks are available in text format at the end of this article • #1 The identifier is all caps. The object is a tuple, which is immutable. Recall that you don’t need parentheses to create a tuple—the comma is sufficient. So, you use an all-uppercase identifier for an immutable object. But that doesn’t stop you from changing the value of FIXED_LOCATION : #2 Neither using an immutable object nor using uppercase identifiers prevents you from changing this value! So, Python doesn’t have constants. But there are tools you can use to mimic constant behaviour depending on the use case you need. In this article I’ll explore one of these: Enums . All The Python Coding Place video courses are included in a single, cost-effective bundle. The courses cover beginner and intermediate level courses, and you also get access to a members-only forum. Get The All Courses Bundle Jargon Corner : Enum is short for enumeration , and you’ll see why soon. But don’t confuse this with the built-in enumerate() , which does something else. See Parkruns, Python’s enumerate and zip, and Why Python Loops Are Different from Other Languages • [Note: This is a Club post] for more on enumerate() . Let’s revisit our friend Alex from an article from a short while ago: “AI Coffee” Grand Opening This Monday . This article explored the program Alex used in his new coffee shop and how the function signature changed over time to minimise confusion and errors when using it. It’s a fun article about all the various types and styles of parameters and arguments you can have in Python functions. But it didn’t address another potential source of error when using this code. So let’s look at a simple version of the brew_coffee() function Alex used to serve his coffee-drinking customers: #3 When you call the function, you pass the coffee you want to this function: #4 And elsewhere in the code, these coffees are defined in a dictionary: #5 If you’ve written code like this in the past, you’ll know that it’s rather annoying—and error-prone—to keep using the strings with the coffee names wherever you need to refer to a specific coffee, such as when passing the coffees to brew_coffee() . The names of the coffees and the parameters that define them do not change. They’re constant. It’s a shame Python doesn’t have constants, you may think. But it has enums… #6 The CoffeeType enum contains seven members. Each member has a name and a value. By convention, you use all-uppercase names for the members since they represent constants. And these enum members behave like constants: #7 When you attempt to reassign a value to a member, Python raises an exception: Traceback (most recent call last): File ..., line 12, in <module> CoffeeType.ESPRESSO = 10 ^^^^^^^^^^^^^^^^^^^ ... AttributeError: cannot reassign member ‘ESPRESSO’ The member names are also contained within the namespace of the Enum class—you use CoffeeType.ESPRESSO rather than just ESPRESSO outside the Enum class definition. So, you get autocomplete, refactor-friendly names, and fewer silent typos. With raw strings, "capuccino" (with a single “p”) can sneak into your code, and nothing complains until a customer is already waiting at the counter. For these enum members to act as constants, their names must be unique. You can’t have the same name appear more than once: #8 You include ESPRESSO twice with different values. But this raises an exception: Traceback (most recent call last): File ..., line 3, in <module> ... ESPRESSO = 8 ^^^^^^^^ ... TypeError: ‘ESPRESSO’ already defined as 1 That’s good news. Otherwise, these enum members wouldn’t be very useful as constants. However, you can have an alias. You can have more than one member sharing the same value: #9 The members MACCHIATO and ESPRESSO_MACCHIATO both have the value 4 . Therefore, they represent the same item. They’re different names for the same coffee: #10 Note that Python always displays the first member associated with a value: CoffeeType.MACCHIATO The output says CoffeeType.MACCHIATO even though you pass CoffeeType.ESPRESSO_MACCHIATO to print() . Incidentally, if you don’t want to have aliases, you can use the @unique decorator when defining the enum class.

You can also access the name and value of an enum member: #11 Here’s the output from this code: CoffeeType.ESPRESSO ESPRESSO 1 The .name attribute is a string, and the .value attribute is an integer in this case: #12 Here’s the output when you display the types: <enum ‘CoffeeType’> <class ‘str’> <class ‘int’> You’ll often use integers as values for enum members—that’s why they’re called enumerations . But you don’t have to: #13 The values are now also strings: CoffeeType.ESPRESSO ESPRESSO espresso You can use these enum members instead of strings wherever you need to refer to each coffee type: #14 …and again when you call brew_coffee() : #15 Now you have a safer, neater, and more robust way to handle the coffee types... and treat them as constants. A Bit More • StrEnum and IntEnum Let’s add some code to brew_coffee() : #16 This version is almost fine. But here’s a small problem: Brewing a CoffeeType.CORTADO with 30ml of coffee and 60ml of milk. Strength level: 2 The output displays CoffeeType.CORTADO since coffee_type refers to an enum member. You’d like the output to just show the name of the coffee! Of course, you can use the .value attribute any time you need to fetch the string. However, to make your coding simpler and more readable, you can ensure that the enum members are also strings themselves without having to rely on one of their attributes. You can use StrEnum instead of Enum : #17 Members of a StrEnum also inherit all the string methods, such as: #18 You call the string method .title() directly on the StrEnum member: Macchiato There’s also an IntEnum that can be useful when you want your enum members to act as integers. Let’s replace the coffee strength values, which are currently integers, with IntEnum members: #19 You could use a standard Enum in this case. But using an IntEnum allows you to manipulate its members directly as integers should you need to do so. Here’s an example: #20 This code is equivalent to printing 3 + 1 . You wouldn’t be able to do this with enums unless you use the .value attributes. And A Couple More Things About Enums Let’s explore a couple of other useful enum features before we wrap up this article. An enum class is iterable. Here are all the coffee types in a for loop: #21 Note that CoffeeType is the class name. But it’s an enum (a StrEnum in this case), so it’s iterable: Brewing a espresso with 30ml of coffee and 0ml of milk. Strength level: 3 Brewing a latte with 30ml of coffee and 150ml of milk. Strength level: 1 Brewing a cappuccino with 30ml of coffee and 100ml of milk. Strength level: 2 Brewing a macchiato with 30ml of coffee and 10ml of milk. Strength level: 3 Brewing a flat_white with 30ml of coffee and 120ml of milk. Strength level: 2 Brewing a ristretto with 20ml of coffee and 0ml of milk. Strength level: 4 Brewing a cortado with 30ml of coffee and 60ml of milk. Strength level: 2 I’ll let you sort out the text displayed to make sure you get ‘ an espresso’ when brewing an espresso and to remove the underscore in the flat white! And there will be times when you don’t care about the value of an enum member. You just want to use an enum to give your constants a consistent name. In this case, you can use the automatic value assignment: #22 Python assigns integers incrementally in the order you define the members for Enum classes. Note that these start from 1 , not 0 . The same integers are used if you use IntEnum classes. However, when you use StrEnum classes, Python behaves differently since the values should be strings in this case: #23 The values are now the lowercase strings representing the members’ names. Of course, the default values you get when you use auto() may be the values you need, after all. This is the case for both enums you created in this article, CoffeeType and CoffeeStrength : #24 Using auto() when appropriate makes it easier to write your code and expand it later if you need to add more enum members. Final Words You can get by without ever using enums. But there are many situations where you’d love to reach for a constant, and an enum will do just fine. Sure, Python doesn’t have constants. But it has enums! Photo by Valeria Boltneva Code in this article uses Python 3.14 The code images used in this article are created using Snappify .

When working with Qt slots and signals in PyQt6 you will discover the @pyqtSlot decorator. This decorator is used to mark a Python function or method as a slot to which a Qt signal can be connected. However, as you can see in our signals and slots tutorials you don't have to use this. Any Python function or method can be used, normally, as a slot for a Qt signals. But elsewhere, in our threading tutorials we do use it. What's going on here? Why do you sometimes use @pyqtSlot but usually not? What happens when you omit it? Are there times when it is required ? What does the documentation say? The PyQt6 documentation has a good explanation: Although PyQt6 allows any Python callable to be used as a slot when connecting signals, it is sometimes necessary to explicitly mark a Python method as being a Qt slot and to provide a C++ signature for it. PyQt6 provides the pyqtSlot() function decorator to do this. Connecting a signal to a decorated Python method has the advantage of reducing the amount of memory used and is slightly faster. From the above we see that: Any Python callable can be used as a slot when connecting signals. It is sometimes necessary to explicitly mark a Python method as being a Qt slot and to provide a C++ signature for it. There is a side-benefit in that marking a function or method with pyqtSlot() reduces the amount of memory used, and makes the slot faster. When is it necessary? Sometimes necessary is a bit vague. In practice the only situation where you need to use pyqtSlot decorators is when working with threads. This is because of a difference in how signal connections are handled in decorated vs. undecorated slots. If you decorate a method with @pyqtSlot then that slot is created as a native Qt slot, and behaves identically If you don't decorate the method then PyQt6 will create a "proxy" object wrapper which provides a native slot to Qt In normal use this is fine, aside from the performance impact (see below). But when working with threads, there is a complication: is the proxy object created on the GUI thread or on the runner thread. If it ends up on the wrong thread, this can lead to segmentation faults. Using the pyqtSlot decorator side-steps this issue, because no proxy is created. When updating my PyQt6 book I wondered -- is this still necessary?! -- and tested removing it from the examples. Many examples continue to work, but some failed. To be safe, use pyqtSlot decorators on your QRunnable.run methods. What about performance? The PyQt6 documentation notes that using native slots "has the advantage of reducing the amount of memory used and is slightly faster". But how much faster is it really, and does decorating slots actually save much memory? We can test this directly by using this script from Oliver L Schoenborn . Updating for PyQt6 (replace PyQt5 with PyQt6 and it will work as-is) and running this we get the following results: See the original results for PyQt5 for comparison. First the results for the speed of emitting signals when connected to a decorated slot, vs non-decorated. python Raw slot mean, stddev: 0.578 0.024 Pyqt slot mean, stddev: 0.587 0.021 Percent gain with pyqtSlot: -2 % The result shows pyqtSlot as 2% slower, but this is negligible (the original data on PyQt5 also showed no difference). So, using pyqtSlot will have no noticeable impact on the speed of signal handling in your applications. Next are the results for establishing connections. This shows the speed, and memory usage of connecting to decorated vs. non-decorated slots. python Comparing mem and time required to create 10000000 connections, 1000 times Measuring for 1000000 connections # connects mem (bytes) time (sec) Raw : 1000000 949186560 (905MB) 9.02 Pyqt Slot : 1000000 48500736 ( 46MB) 1.52 Ratios : 20 6 The results show that decorated slots are about 6x faster to connect to. This sounds like a big difference, but it would only be noticeable if an application was connecting a considerable number of signals. Based on these numbers, if you connected 100 signals the total execution time difference would be 0.9 ms vs 0.15 ms. This is negligible, not to mention imperceptible. Perhaps more significant is that using raw connections uses 20x the memory of decorated connections. Again though, bear in mind that for a more realistic upper limit of connections (100) the actual difference here is 0.09MB vs 0.004MB. The bottom line: don't expect any dramatic improvements in performance or memory usage from using slot decorators, unless you're working with insanely large numbers of signals or making regular connections you won't see any difference at all. That said, decorating your slots is an easy win if you need it. Are there any other reasons to decorate a slot? In Qt signals can be used to transmit more than one type of data by overloading signals and slots with different types . For example, with the following code the my_slot_fn will only receive signals which match the signature of two int values. python @pyqtSlot(int, int) def my_slot_fn(a, b): pass This is a legacy of Qt5 and not recommended in new code. In Qt6 all of these signals have been replaced with separate signals with distinct names for different types. I recommend you follow the same approach in your own code for the sake of simplicity. Conclusion The pyqtSlot decorator can be used to mark Python functions or methods as Qt slots. This decorator is only required on slots which may be connected to across threads, for example the run method of QRunnable objects. For all other slots it can be omitted. There is a very small performance benefit to using it, which you may want to consider when your application makes a large number of signal/slot connections.

January 12, 2026 06:00 AM UTC Wingware Wing Python IDE Version 11.0.7 - January 12, 2026 Wing Python IDE version 11.0.7 has been released. It improves performance of Search in Files on some machines, fixes using stdout.writelines in unit tests run from the Testing tool, reduces CPU used by rescanning for package managers, and fixes analysis failures on incorrect # type: comments. Downloads Be sure to Check for Updates in Wing's Help menu after downloading, to make sure that you have the latest hot fixes. Wing Pro 11.0.7 Wing Personal 11.0.7 Wing 101 11.0.7 Wing 10 and earlier versions are not affected by installation of Wing 11 and may be installed and used independently. However, project files for Wing 10 and earlier are converted when opened by Wing 11 and should be saved under a new name, since Wing 11 projects cannot be opened by older versions of Wing. New in Wing 11 Improved AI Assisted Development Wing 11 improves the user interface for AI assisted development by introducing two separate tools AI Coder and AI Chat . AI Coder can be used to write, redesign, or extend code in the current editor. AI Chat can be used to ask about code or iterate in creating a design or new code without directly modifying the code in an editor. Wing 11's AI assisted development features now support not just OpenAI but also Claude, Grok, Gemini, Perplexity, Mistral, Deepseek, and any other OpenAI completions API compatible AI provider. This release also improves setting up AI request context, so that both automatically and manually selected and described context items may be paired with an AI request. AI request contexts can now be stored, optionally so they are shared by all projects, and may be used independently with different AI features. AI requests can now also be stored in the current project or shared with all projects, and Wing comes preconfigured with a set of commonly used requests. In addition to changing code in the current editor, stored requests may create a new untitled file or run instead in AI Chat. Wing 11 also introduces options for changing code within an editor, including replacing code, commenting out code, or starting a diff/merge session to either accept or reject changes. Wing 11 also supports using AI to generate commit messages based on the changes being committed to a revision control system. You can now also configure multiple AI providers for easier access to different models. For details see AI Assisted Development under Wing Manual in Wing 11's Help menu. Package Management with uv Wing Pro 11 adds support for the uv package manager in the New Project dialog and the Packages tool. For details see Project Manager > Creating Projects > Creating Python Environments and Package Manager > Package Management with uv under Wing Manual in Wing 11's Help menu. Improved Python Code Analysis Wing 11 makes substantial improvements to Python code analysis, with better support for literals such as dicts and sets, parametrized type aliases, typing.Self , type of variables on the def or class line that declares them, generic classes with [...] , __all__ in *.pyi files, subscripts in typing.Type and similar, type aliases, type hints in strings, type[...] and tuple[...] , @functools.cached_property , base classes found also in .pyi files, and typing.Literal[...] . Updated Localizations Wing 11 updates the German, French, and Russian localizations, and introduces a new experimental AI-generated Spanish localization. The Spanish localization and the new AI-generated strings in the French and Russian localizations may be accessed with the new User Interface > Include AI Translated Strings preference. Improved diff/merge Wing Pro 11 adds floating buttons directly between the editors to make navigating differences and merging easier, allows undoing previously merged changes, and does a better job managing scratch buffers, scroll locking, and sizing of merged ranges. For details see Difference and Merge under Wing Manual in Wing 11's Help menu. Other Minor Features and Improvements Wing 11 also adds support for Python 3.14, improves the custom key binding assignment user interface, adds a Files > Auto-Save Files When Wing Loses Focus preference, warns immediately when opening a project with an invalid Python Executable configuration, allows clearing recent menus, expands the set of available special environment variables for project configuration, and makes a number of other bug fixes and usability improvements. Changes and Incompatibilities Since Wing 11 replaced the AI tool with AI Coder and AI Chat , and AI configuration is completely different than in Wing 10, you will need to reconfigure your AI integration manually in Wing 11. This is done with Manage AI Providers in the AI menu. After adding the first provider configuration, Wing will set that provider as the default. You can switch between providers with Switch to Provider in the AI menu. If you have questions, please don't hesitate to contact us at support@wingware.com . January 12, 2026 01:00 AM UTC January 10, 2026 EuroPython Humans of EuroPython: Jakub Červinka EuroPython wouldn’t exist if it weren’t for all the volunteers who put in countless hours to organize it. Whether it’s contracting the venue, selecting and confirming talks & workshops or coordinating with speakers, hundreds of hours of loving work have been put into making each edition the best one yet. Read our latest interview with Jakub Červinka, a member of the EuroPython 2025 Operations Team and organizer of PyConCZ 2026. Thank you for your service to EuroPython, Jakub! Jakub Červinka, member of the Operations Team at EuroPython 2025 EP: What first inspired you to volunteer for EuroPython? The community has always been the biggest draw for me. Having volunteered at our local Python conference previously, I already knew how rewarding it is to be part of the organizing team. When the opportunity to join EuroPython came up, I jumped at it without a second thought. I really like connecting with organizers, speakers, and attendees from across the continent. EP: What&aposs one task you handled that attendees might not realize happens behind the scenes at EuroPython? One year I took on the role of “designated driver”, essentially the person who handles the last-minute, ad-hoc tasks that arise during the conference. It ranged from running out to buy a cart full of hygiene products for the bathrooms, to hauling cases of bottled water when we were about to run dry, to picking up emergency prints on one of the hottest days of the year. These are the kinds of small but critical jobs that keep everything running smoothly, and I enjoy making sure they get done. EP: How did volunteering for EuroPython impact your relationships within the community? In the best possible way. Over the years, I’ve built lasting friendships, met people I had only known from online talks and tutorials, and had the chance to become a familiar face in the community myself. Every EuroPython and every local conference strengthens those connections and leaves you with renewed energy and inspiration to keep contributing. EP: What&aposs one thing you took away from the experience that you still use today? The importance of recognition and appreciation. A simple “thank you” or “great job” from an attendee can mean a lot to volunteers. We’re doing important work, but it’s not our paid job. That experience has made me much more intentional about expressing gratitude to everyone who helps, whether they’re fellow volunteers, staff, or people in service roles. EP: Do you have any tips for first-time EuroPython volunteers? Don’t be afraid to ask questions or offer help, there’s always something that needs doing, and everyone can contribute in their own way. Keep an eye out for small improvements you could suggest, introduce yourself to people, and most importantly, enjoy the experience. Volunteering is as much about building relationships and having fun as it is about getting tasks done. EP: Thank you, Jakub! January 10, 2026 09:49 AM UTC January 09, 2026 Mike Driscoll How to Switch to ty from Mypy Python has supported type hinting for quite a few versions now, starting way back in 3.5. However, Python itself does not enforce type checking. Instead, you need to use an external tool or IDE. The first and arguably most popular is mypy . Microsoft also has a Python type checker that you can use in VS Code called Pyright, and then there’s the lesser-known Pyrefly type checker and language server. The newest type checker on the block is Astral’s ty , the maker of Ruff. Ty is another super-fast Python utility written in Rust. In this article, you will learn how to switch your project to use ty locally and in GitHub Actions. Installation You can run ty with uvx if you do not want to install it by using the following command in your terminal: uvx ty To install ty with uv, run the following: uv tool install ty@latest If you do not want to use uv, you can use the standalone installer. Instructions vary depending on your platform, so it is best to refer to the documentation for the latest information. Note: Technically, you can use pip or pipx to install ty as well. Running ty Locally Once you have ty installed, you can run it using any of the following: Running with uv uv run ty Running without Installation uvx ty Running ty Directly ty check Configuring ty You can configure ty using either of the following: pyproject.toml ty.toml There are many rules that you can change.

Sanjeev Kumar • October 26, 2024 TABLE OF CONTENTS In this article, we explore how to make an agile Kanban board in JIRA using the dynamic duo of React and Node.js, coupled with the flexible data storage capabilities of MongoDB. Leveraging the power of these technologies, we'll delve into the process of designing and building a highly interactive and responsive Kanban board, allowing teams to seamlessly manage and monitor their projects. To augment the board's functionality, we'll integrate Suprsend, a centralised single notification API to power up its notification system. By incorporating Suprsend, developers can take advantage of real-time notifications, enabling teams to stay informed about critical updates and changes on the Kanban board. This added layer of communication enhances collaboration and ensures that everyone involved is promptly notified of relevant events, resulting in improved productivity and seamless project management. Github Repo: GitHub - SuprSend/KanBan Getting Started Creating the folder structure Create the project folder containing two sub-folders named client and server Copy Code Copied ✔ mkdir kanban cd kanban mkdir client server Setting up the Client part Navigate into the client folder via your terminal and create a new React.js project. Copy Code Copied ✔ cd client npx create-react-app ./ Installing dependencies Install Socket.io client API and React Router. React Router is a popular routing library for React applications. It allows us to handle navigation and routing in a declarative manner within the React components. Copy Code Copied ✔ npm install socket.io-client react-router-dom Cleaning up unnecessary data Delete the redundant files such as the logo and the test files from the React app, and update the App.js file to display Hello World as below. Run npm start to verify the app is working fine. Copy Code Copied ✔ function App() { return ( Hello World! ); } export default App; Adding styles Add the following code which contains css for the app into index.css file Copy Code Copied ✔ * { font-family: "Space Grotesk", sans-serif; box-sizing: border-box; } a { text-decoration: none; } body { margin: 0; padding: 0; } .navbar { width: 100%; background-color: black; color: white; height: 10vh; border-bottom: 1px solid #ddd; display: flex; align-items: center; justify-content: center; padding: 20px; } .form__input { min-height: 20vh; display: flex; align-items: center; justify-content: center; } .input { border: 2px solid #008CBA; border-radius: 4px; background-color: #f8f8f8; color: #000; transition: 0.3s; box-sizing: border-box; outline: none; margin: 0 5px; width: 50%; padding: 10px 15px; } .input:focus { border-color: #66afe9; outline: none; } .addCardBtn { font-weight: 900; font-family: cursive; width: 120px; padding: 10px; cursor: pointer; background-color: #5050e9; color: #fff; border: none; outline: none; height: 43px; } .container { width: 100%; min-height: 100%; display: flex; align-items: center; justify-content: space-between; padding: 10px; } .head { border-radius: 10px; text-align: center; text-transform: capitalize; color: white; font-weight: 900; } .pending__head { background-color: rgb(183, 6, 6); } .completed__head { background-color: rgb(0, 104, 0); } .ongoing__head { background-color: rgb(255, 115, 0); } .completed__wrapper, .ongoing__wrapper, .pending__wrapper { width: 32%; min-height: 60vh; display: flex; flex-direction: column; padding: 5px; } .pending__container { background-color: rgba(183, 6, 6, 0.154); } .ongoing__container { background-color: rgba(255, 115, 0, 0.154); } .completed__container { background-color: rgb(0, 104, 0, 0.154); } .cardcontainer { width: 100%; min-height: 10vh; max-height: 40vh; overflow-y: scroll; display: flex; flex-direction: column; padding: 5px; margin-top: 5px; border-radius: 5px; } .pending__items, .ongoing__items, .completed__items { width: 100%; border-radius: 5px; margin-bottom: 10px; background-color: white; padding: 15px; } .comment { text-align: right; font-size: 14px; cursor: pointer; color: rgb(85, 85, 199); } .comment:hover { text-decoration: underline; } .comments__container { padding: 20px; } .comment__form { width: 100%; display: flex; align-items: center; justify-content: center; flex-direction: column; margin-bottom: 30px; } .comment__form > label { margin-bottom: 15px; } .comment__form textarea { width: 80%; padding: 15px; margin-bottom: 15px; } .commentBtn { padding: 10px; width: 200px; background-color: #367e18; outline: none; border: none; color: #fff; height: 45px; cursor: pointer; } .comments__section { width: 100%; display: flex; align-items: center; justify-content: center; flex-direction: column; } .login__form { width: 100%; height: 100vh; display: flex; flex-direction: column; align-items: center; justify-content: center; } .login__form > label { margin-bottom: 15px; } .login__form > input { width: 70%; padding: 10px 15px; margin-bottom: 15px; } .btn { padding: 15px; cursor: pointer; margin: 10px; font-size: 16px; outline: none; width: 200px; background-color: #4CAF50; border: 2px solid white; color: white; text-align: center; text-decoration: none; transition-duration: 0.4s; border-radius: 4px; } .btn:hover { background-color: white; color: #4CAF50; border: 2px solid #4CAF50; } Setting up the server Navigate into the server folder and create a package.json file. Copy Code Copied ✔ cd server npm init -y Installing dependencies Install Express.js,Mongoose, dotenv, Mongodb Driver, CORS and Socket.io Server API. Express.js is a fast, minimalist framework that provides several features for building web applications in Node.js. CORS is a Node.js package that allows communication between different domains. Copy Code Copied ✔ npm install express cors socket.io Index.js Create an index.js file – the entry point to the web server. Copy Code Copied ✔ touch index.js Setting up the server Set up a simple Node.js server using Express.js. Copy Code Copied ✔ const express = require("express"); const app = express(); const PORT = process.env.PORT || 4000; app.use(express.urlencoded({ extended: true })); app.use(express.json()); app.get("/home", (req, res) => { res.json({ message: "Hello world", }); }); app.listen(PORT, () => { console.log(`Server listening on ${PORT}`); }); Import the HTTP and the CORS library to allow data transfer between the client and the server domains. Copy Code Copied ✔ const express = require("express"); const app = express(); const PORT = process.env.PORT || 4000; app.use(express.urlencoded({ extended: true })); app.use(express.json()); // Newly added imports const http = require("http").Server(app); const cors = require("cors"); app.use(cors()); app.get("/home", (req, res) => { res.json({ message: "Hello world", }); }); http.listen(PORT, () => { console.log(`Server listening on ${PORT}`); }); Creating schemas and models: Create Model using Mongoose in a file named models.js: Copy Code Copied ✔ const mongoose = require('mongoose'); const Schema = mongoose.Schema; const UserSchema = new Schema({ username: { type: String, required: true }, password: { type: String, required: true }, }); const User = mongoose.model('User', UserSchema); module.exports = { User}; We can similarly create models for tasks,boards comments. Adding Imports Add Mongodb and Mongoose ODM and import models. Connect to the MongoDb Database. You can create a database for free on Mongodb. Make sure to keep the MONGODB_URI in .env instead of hardcoding it. Copy Code Copied ✔ const express = require("express"); const app = express(); const cors = require("cors"); const http = require("http").Server(app); const PORT = 4000; const mongoose = require("mongoose"); const dotenv = require("dotenv"); const { User } = require("./models"); dotenv.config(); app.use(cors()); app.use(express.urlencoded({ extended: true })); app.use(express.json()); mongoose .connect(process.env.MONGODB_URI, { useNewUrlParser: true, useUnifiedTopology: true, }) .then(() => console.log("Database connected!")) .catch((err) => console.error(err)); // Rest of the code Adding socket.io Next, add Socket.io to the project to create a real-time connection. Before the app.get()block, copy the code below. Copy Code Copied ✔ //New imports ..... const socketIO = require('socket.io')(http, { cors: { origin: "http://localhost:3000" } }); // Add this before the app.get() block socketIO.on('connection', (socket) => { console.log(`${socket.id} User connected!`); socket.on('disconnect', () => { socket.disconnect() console.log(' User disconnected'); }); }); From the code snippet above, the socket.io("connection") function establishes a connection with the React app, then creates a unique ID for each socket and logs the ID to the console whenever a user visits the web page. When you refresh or close the web page, the socket fires the disconnect event showing that a user has disconnected from the socket. OPTIONAL Install Nodemon. Nodemon is a Node.js tool that automatically restarts the server after detecting file changes, and Socket.io allows us to configure a real-time connection on the server. Configure Nodemon by adding the start command to the list of scripts in the package.json file. The code snippet below starts the server using Nodemon. Copy Code Copied ✔ "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "nodemon index.js" }, You can now run the server with Nodemon by using the command below. Copy Code Copied ✔ npm start If you are not using nodemon, either run the server with the command "node index.js" or modify the script by adding the start command to the list of scripts in the package.json file as shown below: Copy Code Copied ✔ "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "node index.js" }, Developing UI/UX with Kanban Board Features Let's create the UI for the application. It will have three pages: the Login page, Task page – the main part of the application, and The Comments page – where users can comment on each task. Navigate into client/src and create a components folder containing the Login.js, Task.js, and Comments.js files. Copy Code Copied ✔ cd client/src mkdir components cd components touch Login.js Task.js Comments.js Modify the App.js file to setup the routes. Copy Code Copied ✔ import { BrowserRouter, Route, Routes } from "react-router-dom"; import Comments from "./components/Comments"; import Task from "./components/Task"; import Login from "./components/Login"; function App() { return ( } /> } /> } /> ); } export default App; The Register Page In this, User has to enter an email and a password. The details are stored in the database. After successful registration,an alert is displayed and user is redirected to login page: Copy Code Copied ✔ import React, { useState } from "react"; import { useNavigate } from "react-router-dom"; const Register = () => { const [username, setUsername] = useState(""); const [password, setPassword] = useState(""); const navigate = useNavigate(); const handleRegister = async (e) => { e.preventDefault(); try { const response = await fetch("http://localhost:4000/register", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ username, password }), }); if (!response.ok) { throw new Error(`Error registering user: ${response.statusText}`); } const data = await response.json(); console.log(data); alert("Registered Successfully"); navigate("/login"); } catch (error) { console.error(error); } }; return ( Enter your email setUsername(e.target.value)} value={username} /> Choose a password setPassword(e.target.value)} // value={password} /> Register navigate("/login")}> Log In ); }; export default Register; The Login page Here, the application accepts the username and password, verifies the details from database and if credentials supplied are correct, alert is displayed. Copy Code Copied ✔ import React, { useState } from "react"; import { useNavigate } from "react-router-dom"; const Login = () => { const [username, setUsername] = useState(""); const [password, setPassword] = useState(""); const navigate = useNavigate(); const handleLogin = async (e) => { e.preventDefault(); const response = await fetch("http://localhost:4000/login", { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ username, password }), }); const data = await response.json(); // console.log(data); if (response.ok) { console.log("Login successful:", data); localStorage.setItem('userId', data.userId); alert(data.message); navigate("/task"); } else { console.log("Login failed:", data); alert(data.message); } }; return ( Provide your email setUsername(e.target.value)} value={username} /> Enter your password setPassword(e.target.value)} // value={password} /> Log In ); }; export default Login; Task Page We'll divide the layout into 2 components namely: AddTask.js – the form input section, and TaskWindow.js – the section containing the tasks. Copy Code Copied ✔ cd src/components touch Navig.js AddTask.js TaskWindow.js Code for Task.js will look something like this Copy Code Copied ✔ import React from "react"; import AddTask from "./AddTask"; import TaskWindow from "./TaskWindow"; import socketIO from "socket.io-client"; const socket = socketIO.connect("http://localhost:4000"); const Task = () => { return ( KanBan Board ); }; export default Task; AddTask.js looks something like this: Copy Code Copied ✔ import React, { useState } from "react"; const AddTask = ({ socket }) => { const [task, setTask] = useState(""); const handleAddTask = (e) => { e.preventDefault(); setTask(""); }; return ( Add Task setTask(e.target.value)} /> ADD CARD ); }; export default AddTask; Code for TaskWindow is as follows Copy Code Copied ✔ import React from "react"; import { Link } from "react-router-dom"; const TaskWindow = ({ socket }) => { return ( Pending Tasks Debug the Notification center 2 Comments Ongoing Tasks Add Comment Completed Tasks Debug the Notification center 2 Comments ); }; export default TaskWindow; Comments Page Comments page will have some code like this: Copy Code Copied ✔ import React, { useEffect, useState } from "react"; import socketIO from "socket.io-client"; import { useParams } from "react-router-dom"; const socket = socketIO.connect("http://localhost:4000"); const Comments = () => { const [comment, setComment] = useState(""); const addComment = (e) => { e.preventDefault(); console.log({ comment, userId: localStorage.getItem("userId"), }); setComment(""); }; return ( Add a comment setComment(e.target.value)} rows={5} id="comment" name="comment" required > ADD COMMENT Existing Comments ); }; export default Comments; Adding Drag and Drop feature: React-beautiful-dnd (Drag and Drop) is a library developed by Atlassian that aims to provide a beautiful, accessible drag and drop experience for your React.js applications. Drag and Drop functionality can greatly enhance the user experience by allowing users to physically move elements within your application, often for reordering lists or transferring items between lists. Install React Beautiful DND and ensure you are not using React in strict mode. (Check src/index.js). npm install react-beautiful-dnd In server/index.js file,create an object containing all the dummy data for each task category. Copy Code Copied ✔ const fetchID = () => Math.random().toString(36).substring(1, 9); let tasks = { pending: { title: "pending", items: [ { id: fetchID(), title: "Provide the proposed designs", comments: [], }, ], }, ongoing: { title: "ongoing", items: [ { id: fetchID(), title: "Refine and finalise the designs", comments: [ { name: "John", text: "Verify designs for copyright issues", id: fetchID(), }, ], }, ], }, completed: { title: "completed", items: [ { id: fetchID(), title: "Create posters", comments: [ { name: "Doe", text: "Check the dimensions", id: fetchID(), }, ], }, ], }, }; app.get("/home", (req, res) => { res.json(tasks); }); Now, let's fetch the tasks in TaskWindow.js file. Copy Code Copied ✔ import React, { useState, useEffect } from "react"; import { Link } from "react-router-dom"; const TaskWindow = ({ socket }) => { const [tasks, setTasks] = useState({}); useEffect(() => { function fetchTasks() { fetch("http://localhost:4000/home") .then((res) => res.json()) .then((data) => { console.log(data); setTasks(data); }); } fetchTasks(); }, []); return ( {Object.entries(tasks).map((task) => ( {task[1].title} Tasks {task[1].items.map((item, index) => ( {item.title} {item.comments.length > 0 ? `View Comments` : "Add Comment"} ))} ))} ); }; export default TaskWindow; The DragDropContext accepts a prop on DragEnd, which fires immediately after dragging an element. Copy Code Copied ✔ const handleDragEnd = ({ destination, source }) => { if (!destination) return; if ( destination.index === source.index && destination.droppableId === source.droppableId ) return; socket.emit("taskDragged", { source, destination, }); }; Now, create the taskDragged event's listener in server socketIO.on("connection", (socket) => { console.log(`${socket.id} user connected!`); socket.on("taskDragged", (data) => { console.log(data); }); socket.on("disconnect", () => { socket.disconnect(); console.log("User disconnected"); }); }); Now, create the taskDragged event's listener in server Copy Code Copied ✔ const handleDragEnd = ({ destination, source }) => { if (!destination) return; if ( destination.index === source.index && destination.droppableId === source.droppableId ) return; socket.emit("taskDragged", { source, destination, }); }; Now, create the taskDragged event's listener in server socketIO.on("connection", (socket) => { console.log(`${socket.id} user connected!`); socket.on("taskDragged", (data) => { console.log(data); }); socket.on("disconnect", () => { socket.disconnect(); console.log("User disconnected"); }); }); But there's a problem. The dragged item doesn't remain at its destination. So let's modify the code. The final code looks something like this: Copy Code Copied ✔ import React, { useState, useEffect } from "react"; import { DragDropContext, Droppable, Draggable } from "react-beautiful-dnd"; import { Link } from "react-router-dom"; const TaskWindow = ({ socket }) => { const [tasks, setTasks] = useState({}); useEffect(() => { function fetchTasks() { // const userId = localStorage.getItem("userId"); fetch(`http://localhost:4000/home`) .then((res) => res.json()) .then((data) => { console.log("Fetched tasks:", data); setTasks(data); }); } fetchTasks(); }, []); useEffect(() => { socket.on("tasks", (data) => { console.log("Received updated tasks:", data); setTasks(data); }); }, [socket]); const handleDragEnd = ({ destination, source }) => { if (!destination) return; if ( destination.index === source.index && destination.droppableId === source.droppableId ) { return; } socket.emit("taskDragged", { source, destination, }); }; if (!tasks) { return Loading tasks... ; } return ( {Object.entries(tasks).map((task) => ( {task[1].title} tasks {(provided) => ( {task[1].items.map((item, index) => ( {(provided) => ( {item.title} {item.comments.length > 0 ? `View Comments` : "Add Comment"} )} ))} {provided.placeholder} )} ))} ); }; export default TaskWindow; Adding a task For adding a task, we will use the given code Copy Code Copied ✔ import React, { useState } from "react"; const AddTask = ({ socket }) => { const [task, setTask] = useState(""); const handleAddTodo = (e) => { e.preventDefault(); socket.emit("createTask", { task }); setTask(""); }; return ( Add Task setTask(e.target.value)} /> ADD CARD ); }; export default AddTask; We'll have to include the listener for the same in server Copy Code Copied ✔ socketIO.on("connection", (socket) => { console.log(`${socket.id} user connected.`); socket.on("createTask", (data) => { const newTask = { id: fetchID(), title: data.task, comments: [] }; tasks["pending"].items.push(newTask); socket.emit("tasks", tasks); }); // ... Other listeners }); Finalizing the Comments Page Now we'll finish the comments page. Copy Code Copied ✔ import React, { useEffect, useState } from "react"; import socketIO from "socket.io-client"; import { useParams } from "react-router-dom"; const socket = socketIO.connect("http://localhost:4000"); const Comments = () => { const { category, id } = useParams(); const [comment, setComment] = useState(""); const addComment = (e) => { e.preventDefault(); socket.emit("addComment", { comment, category, id, userId: localStorage.getItem("userId"), }); setComment(""); }; return ( Add a comment setComment(e.target.value)} rows={5} id="comment" name="comment" required > ADD COMMENT Existing Comments ); }; export default Comments; Again, we'll add the listener in server.js Copy Code Copied ✔ socket.on("addComment", (data) => { const { category, userId, comment, id } = data; const taskItems = tasks[category].items; for (let i = 0; i Also, we need to retreive all the comments which are already present. Copy Code Copied ✔ const Comments = () => { const { category, id } = useParams(); const [comment, setComment] = useState(""); // Add this: const [commentList, setCommentList] = useState([]); useEffect(() => { socket.on("comments", (data) => setCommentList(data)); }, []); // ... after this return ( {/* ... rest of the code */} Existing Comments {/* Add the following code */} {commentList.map((comment) => ( {comment.text} by {comment.name} ))} {/* ... rest of the code */} ); }; Finally add this code to load the comments when the page is loaded Copy Code Copied ✔ useEffect(() => { socket.emit("fetchComments", { category, id }); }, [category, id]); So finally Comments.js looks like this: Copy Code Copied ✔ import React, { useEffect, useState } from "react"; import socketIO from "socket.io-client"; import { useParams } from "react-router-dom"; const socket = socketIO.connect("http://localhost:4000"); const Comments = () => { const { category, id } = useParams(); const [comment, setComment] = useState(""); const [commentList, setCommentList] = useState([]); useEffect(() => { socket.emit("fetchComments", { category, id }); }, [category, id]); useEffect(() => { socket.on("comments", (data) => setCommentList(data)); }, []); const addComment = (e) => { e.preventDefault(); socket.emit("addComment", { comment, category, id, userId: localStorage.getItem("userId"), }); setComment(""); }; return ( Add a comment setComment(e.target.value)} rows={5} id="comment" name="comment" required > ADD COMMENT Existing Comments {commentList.map((comment) => ( {comment.text} by{" "} {comment.name} ))} ); }; export default Comments; Finally, add the listener for the same in server.js: Copy Code Copied ✔ socket.on("fetchComments", (data) => { const { category, id } = data; const taskItems = tasks[category].items; for (let i = 0; i Implementing Suprsend Notifications: SuprSend is a notification infrastructure as a service platform for easily creating, managing and delivering notifications to your end users. SuprSend has all the features set which enable you to send notifications in a reliable and scalable manner, as well as take care of end-user experience, thereby eliminating the need to build any notification service in-house. Firstly create an account on Suprsend. Install SuprSend Node.js SDK in the backend Copy Code Copied ✔ npm install @suprsend/node-sdk # to upgrade to latest SDK version npm install @suprsend/node-sdk@latest Initialize the SDK in server.js Copy Code Copied ✔ const {Suprsend} = require("@suprsend/node-sdk"); // Initialize SDK const supr_client = new Suprsend("WORKSPACE KEY", "WORKSPACE SECRET"); Replace WORKSPACE KEY and WORKSPACE SECRET with your workspace values. You will get both the tokens from Suprsend dashboard (Settings page -> "API keys" section) Create a New User. To create a new user or to update the profile of an existing user, you'll have to first instantiate the user object. Call supr_client.user.get_instance to instantiate user object. Copy Code Copied ✔ const distinct_id = "__uniq_user_id__" // Unique id of user in your application. const user = supr_client.user.get_instance(distinct_id) // Instantiate User profile Add the User Channels. Use user.add_* method(s) to add user channels in a profile Copy Code Copied ✔ user.add_email(`${distinct_id}`); /* For adding slack using email of user and access token of slack app,do this: */ user.add_slack( { "email": `${distinct_id}`, "Access_token": process.env.ACCESS_TOKEN } ) /* OR to add the incoming webhook for sending notification to slack channel, do this: */ user.add_slack( { "incoming_webhook": { "url": process.env.INCOMING_WEBHOOK } }) // After setting the channel details on user-instance, call save() const response1 = user.save() //save() returns promise When you call user.save(), the SDK internally makes an HTTP call to SuprSend Platform to register this request, and you'll immediately receive a response indicating the acceptance / failure status. Copy Code Copied ✔ // Response structure { "success": true, // if true, request was accepted. "status": "success", "status_code": 202, // http status code "message": "OK" } { "success": false, // error will be present in message "status": "fail", "status_code": 500, // http status code "message": "error message" } NOTE : For including slack notifications, you should use OAuth method to grant access to your slack workspace. A good way would be to use Slack Button(refer to docs : https://api.slack.com/docs/slack-button ) which gives incoming webhooks , slash commands and bot users wrapped in OAuth. Create a workflow on SuprSend platform. For Event based workflow trigger, you'll have to create the workflow on SuprSend Platform. Once the workflow is created, Add an import and then you can pass the Event name defined in workflow configuration with the help of supr_client.track_event method. Variables added in the template should be passed as event properties. Copy Code Copied ✔ const express = require("express"); const app = express(); const cors = require("cors"); const http = require("http").Server(app); const PORT = 4000; const mongoose = require("mongoose"); const dotenv = require("dotenv"); const { Suprsend } = require("@suprsend/node-sdk"); const { Event } = require("@suprsend/node-sdk"); // Rest of the code const event = new Event(distinct_id, event_name, properties); // Track event const response = supr_client.track_event(event); response.then((res) => console.log("response", res)); Event naming guidelines : When you create an Event or a property, please ensure that the Event Name or Property Name does not start with $ or ss_ , as we have reserved these symbols for our internal events and property names. When you call supr_client.track_event, the SDK internally makes an HTTP call to SuprSend Platform to register this request, and you'll immediately receive a response indicating the acceptance status. Copy Code Copied ✔ { "success": true, // if true, request was accepted. "status": "success", "status_code": 202, // http status code "message": "Accepted", } { "success": false, // error will be present in message "status": "fail", "status": 400, // http status code "message": "error message", } The below image demonstrates a demo notification sent upon creating a task in Kanban Board to slack You can access the project's Github repo from here: GitHub - SuprSend/KanBan Wrapping Up Throughout the tutorial, we covered the essential steps of designing and building a highly interactive and responsive Kanban board. From setting up the development environment to implementing the board's core features, developers now have a solid foundation to create their own customized Kanban boards tailored to their specific project requirements. Additionally, by integrating Suprsend's notification capabilities, teams can ensure that all stakeholders stay informed about important updates and changes happening on the Kanban board in real-time. This not only fosters seamless communication but also enables swift decision-making and rapid response to project developments.

Report Abuse Vaibhav Gupta Posted on Jan 12 Building a React Dashboard in 2026: What Actually Matters (From a Dev Perspective) # webdev # react # opensource # frontend React dashboards are everywhere - analytics tools, internal admin panels, SaaS backends, and side projects. But most guides focus on UI screenshots or component libraries, not on what actually makes a React dashboard usable, scalable, and maintainable. This post breaks down what actually matters when building a React dashboard today - based on real-world patterns, not theory. 1. What a “React Dashboard” Really Is A React dashboard isn’t just cards and charts. At its core, it’s: A layout system (navigation, sidebars, responsiveness) A data display layer (tables, charts, KPIs) A state & data flow strategy A component architecture that survives long-term changes Most dashboards fail because one of these is ignored. 2. Layout First, UI Second Before picking a UI library or chart package, lock down your layout. Decide early: Sidebar vs top navigation (or hybrid) Fixed vs collapsible navigation Mobile behavior (dashboards break here first) Route-based layouts (not page-based) Rule of thumb: If your layout isn’t reusable across pages, you’ll fight CSS forever. 3. Component Structure That Scales A common mistake is dumping everything into /components . A more scalable structure: layouts/ → dashboard shell features/ → domain-specific logic (users, billing, analytics) ui/ → reusable UI primitives routes/ or pages/ → thin wrappers only This keeps the codebase readable even after months of iteration. 4. Styling: Utility-First Works Better for Dashboards Dashboards evolve constantly. Utility-first styling works well because: Faster iteration Predictable spacing Easy dark mode Less CSS overhead Dashboards benefit more from consistency than uniqueness. 5. Data Handling: Keep It Boring Dashboards don’t need experimental state management. What usually works best: Server-driven data Simple query caching Clear loading & empty states Section-level error handling If one widget fails, the entire dashboard shouldn’t. 6. Charts Are Secondary, Clarity Is Primary Charts are useful, but often overused. Ask instead: Is the data readable at a glance? Can users compare values easily? Do empty states explain why there’s no data? A clean table often beats a fancy chart. 7. When Using a Starter Dashboard Makes Sense Building from scratch is great for learning - not always for shipping. Starter dashboards help when: Layout patterns are already solved Responsiveness is handled Accessibility basics are covered Code is readable and extensible Open-source dashboards are especially useful for learning real-world patterns. 8. Open Source Dashboards as Learning Material Even if you don’t use them directly, reading open-source dashboard code teaches: Layout composition Routing structure Theme handling Reusable component design GitHub is often a better teacher than tutorials. Final Thoughts A good React dashboard isn’t about flashy UI. It’s about: Clear structure Predictable behavior Easy extensibility If your dashboard doesn’t fight you when adding new features, you’re on the right track.

https://replit.com/customers/spellbook | Spellbook — Customer Story - Replit Agent Products Agent Design Database Publish Security Integrations Mobile For Work Teams Replit for teams to build together Enterprise Replit with Enterprise-grade security & controls Use Cases Business Apps Rapid Prototyping Roles Enterprise PM Designers Operations Software Developers Small Businesses SMB owners Founders Resources Get Started Docs Community Expert Network Inspiration Customer Stories Gallery Blog News Pricing Careers Agent Contact sales Log in Sign up Products For Work Resources Pricing Careers Contact sales Log in Start building From Idea to 17x Growth: How Spellbook Created a Prototype on Replit and Raised Funding 17x growth 30,000+ waitlist signups 3,000+ customers 17x growth 30,000+ waitlist signups 3,000+ customers "I can honestly say that if it weren't for Replit and that prototype that I was able to build in two weeks, it just wouldn't have happened. The opportunity would have perished. Someone else would have done it first... Replit for us was the way to actually do it. And it actually completely and utterly changed the trajectory of our company in a massive way." Scott Stevenson Co-founder & CEO, Spellbook The challenge: When inspiration strikes, time is everything In summer 2022, as GPT-3 emerged, Scott had a lightning-bolt moment: What if lawyers could have the same AI assistance for contracts that developers had for code? The problem? Scott was already running a company with existing customers, board meetings, and daily operations. Like most founders with mature products, he faced the brutal reality that inspiration is perishable —and the infrastructure overhead to test new ideas often kills them before they can prove their worth. "When you have customers, time becomes so scarce. Even if you're a technical founder like me with experience building software, you just don't have the time to spin up infrastructure, write all the boilerplate... It's brutally time consuming," Scott explains. "Most companies are horrible at executing on these strokes of inspiration because you just never find the time." Scott Stevenson Co-founder & CEO, Spellbook Why Replit: Cutting through the boilerplate Scott needed to move fast—before ChatGPT launched and flooded the market with competitors. Traditional development would have meant weeks of infrastructure setup, database configuration, and deployment pipelines. Time he simply didn't have. "Without Replit, this prototype just never would have happened. I would have been too busy," Scott reflects. "We're often addicted to doing the prerequisites—standing up infrastructure and boilerplate things because it feels good and certain, but boilerplate things are not valuable when you are testing new ideas (because validation is all that matters at first)." Replit eliminated all that overhead, letting Scott focus on the core idea: building AI for lawyers. Building the MVP: Two weeks that changed everything Scott needed to move fast—before ChatGPT launched and flooded the Working evenings and weekends while still running Rally, Scott used Replit to build what would become Spellbook—an AI copilot for contract review and drafting integrated directly into Microsoft Word. The prototype featured: Auto-complete for legal language similar to AI code completion Microsoft Word integration for seamless lawyer workflow GPT powered contract assistance before most people knew what generative AI could do "I built this on my own in two weeks using Replit on evenings and weekends because I still had to run the company, do board meetings, do our normal plan we were supposed to be doing," Scott says. Scott Stevenson Co-founder & CEO, Spellbook The results: From side project to major success What Scott thought would be "a cool little marketing splash" became a complete business transformation: 📈 Explosive growth stats: 30,000+ waitlist signups in just 3 months More revenue in one quarter than their previous product generated in 3 years 100+ employees and significant funding raised 17x growth over the past two years 3,000+ customers including Nestlé, Crocs, Fender, and eBay ⚡ Speed to market advantage: By launching before ChatGPT, Spellbook established itself as the first generative AI tool for lawyers—a positioning that proved crucial as the market exploded with competitors. "Without Replit, we would have come after ChatGPT and been swamped in a sea of other similar products. Us being out ahead really helped," Scott notes. The bigger picture: Radical agility in the AI age Scott's experience with Replit fundamentally changed how he thinks about innovation: "I think about all the perishable ideas in your company. You go to a CEO and say, 'You have all these ideas that no one executes on.' What if you can pitch a company where that idea you had in a board meeting today can be prototyped by this afternoon? You actually should expect that from your team." Scott's philosophy: If a new model comes out with significant capabilities, you should have it live and testing in real use cases within two days.

Report Abuse Sainath Patil Posted on Nov 29, 2025 • Edited on Dec 5, 2025 Mastering Terraform File Structure – From Chaos to Clean Architecture # terraform # cleancode # devops # architecture When working with Infrastructure as Code (IaC), writing the resource definitions is only half the job. The other half, and often the more important part, is organizing your Terraform configuration so it's scalable, readable, and easy to maintain over time. Today, I focused on understanding and implementing Terraform file structure best practices, and here's a breakdown of everything I learned and applied. Why File Structure Matters in Terraform Terraform loads all .tf files in the current directory and merges them into a single configuration. The filenames don’t affect execution, but they have a massive impact on: Readability Collaboration within teams Debugging and maintenance Scaling configurations as infrastructure grows Recommended Terraform Project Structure project-root/ ├── backend.tf ├── provider.tf ├── variables.tf ├── locals.tf ├── main.tf ├── vpc.tf ├── security.tf ├── compute.tf ├── storage.tf ├── database.tf ├── outputs.tf ├── terraform.tfvars └── README.md Enter fullscreen mode Exit fullscreen mode Environment-Based Structure environments/ dev/ staging/ production/ modules/ shared/ Enter fullscreen mode Exit fullscreen mode Service-Based Structure infrastructure/ networking/ compute/ security/ storage/ data/ Enter fullscreen mode Exit fullscreen mode Conclusion Terraform isn’t just about creating infrastructure. It’s about creating maintainable infrastructure. A clean file structure is a superpower that helps teams collaborate efficiently and scale infrastructure reliably.

Report Abuse Arshad Yaseen Posted on Jul 23, 2025 • Edited on Sep 26, 2025 Building a TypeScript Library in 2025 # typescript # bunjs # programming If you've built a TypeScript library recently, you know the pain. You spend more time wrestling with build configurations than actually writing code. Your tsup builds take 4 seconds. It's 2025. We can do better. The TypeScript ecosystem has been missing a tool that combines: Lightning-fast builds (sub-100ms, not multi-second) Zero-config ergonomics that scale with complexity Modern TypeScript features like isolatedDeclarations Built-in intelligence for common library tasks Enter the Speed Revolution Here's what modern TypeScript library development should look like: # Traditional approach $ tsup src/index.ts ✓ Build completed in 1.4s # What's possible in 2025 with bunup $ bunup src/index.ts ✓ Build completed in 37ms Enter fullscreen mode Exit fullscreen mode 37 milliseconds. Not 1.8 seconds. Not 400ms. 37ms. Bunup is powered by Bun's native bundler, making it fast by default with instant TypeScript declaration generation. This isn't just about saving time (though saving 1.7+ seconds per build adds up). It's about changing how you develop . When builds are instant, you can: Iterate faster during development Run builds in watch mode without battery drain Include builds in pre-commit hooks without friction Actually enjoy the development process Modern TypeScript: Isolated Declarations TypeScript 5.5 introduced isolatedDeclarations - a game-changer for library authors that most tools still don't properly support. Why It Matters Traditional declaration generation analyzes your entire codebase to infer types: // Old way - requires whole-program analysis export function getUserData ( id : string ) { return database . users . find ( user => user . id === id ); // Inferred return type } Enter fullscreen mode Exit fullscreen mode With isolatedDeclarations , you're explicit about your public API: // Modern way - explicit, fast, reliable export function getUserData ( id : string ): Promise < User | null > { return database . users . find ( user => user . id === id ); } Enter fullscreen mode Exit fullscreen mode The Benefits 10x faster declaration generation More predictable types for library consumers Better encapsulation - your internal types stay internal Clearer intent - you explicitly define what's public Enable it in your tsconfig.json : { "compilerOptions" : { "declaration" : true , "isolatedDeclarations" : true } } Enter fullscreen mode Exit fullscreen mode Modern bundlers should embrace this, not fight it. Beyond Speed: Beautiful Ergonomics Fast builds are just the beginning. Modern library tooling should understand your needs: Package Exports // bunup.config.ts export default defineConfig ({ entry : [ ' src/index.ts ' ], plugins : [ exports ()] }); Enter fullscreen mode Exit fullscreen mode Your package.json automatically gets: { "main" : "./dist/index.cjs" , "module" : "./dist/index.js" , "types" : "./dist/index.d.ts" , "exports" : { "." : { "import" : { "types" : "./dist/index.d.ts" , "default" : "./dist/index.js" }, "require" : { "types" : "./dist/index.d.cts" , "default" : "./dist/index.cjs" } } } } Enter fullscreen mode Exit fullscreen mode No more manual exports field maintenance. No more forgetting the types field. No more mismatched paths. Unused Dependencies plugins : [ unused ()] Enter fullscreen mode Exit fullscreen mode Get warnings about: Dependencies you're not actually using Dev dependencies that should be regular dependencies Missing peer dependencies And a lot more beautiful plugins that you love. Monorepo Support Building multiple packages? Bunup workspaces make it effortless: // bunup.config.ts export default defineWorkspace ([ { name : " core " , root : " packages/core " , config : { entry : [ " src/index.ts " ], format : [ " esm " , " cjs " ] } }, { name : " utils " , root : " packages/utils " , config : { entry : [ " src/index.ts " ], format : [ " esm " ] } } ]); Enter fullscreen mode Exit fullscreen mode Build all packages with a single command, with incremental builds that only rebuild what's changed. Perfect for design systems, component libraries, and complex projects. The Full Developer Experience Here's what building a TypeScript library looks like in 2025: Initial Setup (10 seconds) bunx bunup@latest --new Enter fullscreen mode Exit fullscreen mode You get: TypeScript configured with isolatedDeclarations Bun-powered testing setup Biome for linting and formatting GitHub Actions for CI/CD Automatic npm publishing workflow Development Workflow bun run dev # Watch mode with instant rebuilds bun run test # Lightning-fast tests bun run build # Production build in ~37ms Enter fullscreen mode Exit fullscreen mode Publishing bun run release Enter fullscreen mode Exit fullscreen mode Automatically: Bumps version Generates changelog Creates GitHub release Publishes to npm with provenance Real-World Performance Comparison I tested this with a medium-sized TypeScript library (15 source files, 3 entry points): Tool Build Time Rebuild Time tsup 1.8s 0.6s unbuild 1.1s 0.4s tsdown 108ms 34ms bunup 37ms 8ms That's not a typo. 37 milliseconds for a complete build with TypeScript declarations. ⭐ Star bunup on GitHub and join the speed revolution. The future of TypeScript library development is here. It's fast, it's simple, and it's available at bunup.dev today.

Report Abuse Aditya singh Posted on Dec 30, 2025 30 Core Algorithm:EP-05: Sliding Window Algorithm # algorithms # computerscience # performance Why the Sliding Window Algorithm Is Really About Preserving Context Over Time Many systems don’t fail because they lack information. They fail because they keep forgetting what just happened. Sliding Window exists to solve that problem. It isn’t about optimizing loops. It isn’t about fixed-size subarrays. It’s about maintaining relevant context as the system moves forward. The Cost of Forgetting Too Much Consider a system evaluating a condition repeatedly over a sequence. A naive approach recalculates everything from scratch each time. Every step starts fresh, ignoring the fact that most of the context hasn’t changed. That approach works. It’s also wasteful. When input shifts gradually, recomputation destroys continuity. The system keeps answering the same questions again, paying the full cost every time. Progress happens. But memory is lost. Sliding Window: Carrying Context Forward Sliding Window changes the unit of work. Instead of recomputing from zero, it asks: “What changed since the last step?” One element enters the window. One element leaves. Everything else stays. The algorithm preserves just enough state to keep decisions accurate — without carrying the entire history. This isn’t optimization by cleverness. It’s optimization by restraint. The Core Mechanism At a structural level, Sliding Window looks like this: initialize window state for each new element: add new element to window while window violates constraint: remove old element from window evaluate window Enter fullscreen mode Exit fullscreen mode The details vary. The principle doesn’t. State is updated incrementally. Nothing is recalculated unless it has to be. Why Sliding Window Depends on Time Sliding Window assumes something fundamental: Order matters. The window moves forward, never backward. Decisions are based on recent information, not global knowledge. That’s why the technique fits naturally in problems involving: streams time-series data rate limits rolling averages bounded histories When time flows in one direction, sliding windows become inevitable. Sliding Window as a Stability Mechanism Most sliding window problems aren’t about finding something. They’re about keeping a condition stable over a moving boundary. A maximum that must stay within a range. A frequency that must not exceed a limit. A latency that must remain acceptable. The window expands when it’s safe. It contracts when it isn’t. That constant adjustment prevents sudden spikes and silent drift. Fixed vs Variable Windows Isn’t the Point Fixed-size windows and variable-size windows are usually taught as different patterns. They aren’t. They’re the same idea applied under different constraints. Fixed windows assume stability is guaranteed by size. Variable windows assume stability must be enforced dynamically. In both cases, the window exists to protect context from being lost as the system advances. Where Sliding Window Breaks Down Sliding Window relies on locality. Recent information must be more relevant than distant information. If that assumption fails, the window loses meaning. That’s why the technique struggles with: problems requiring global history non-linear dependencies conditions that depend on distant past states Sliding Window doesn’t fail silently. It simply stops being applicable. The Trade-off It Makes Explicit Sliding Window trades completeness for continuity. It doesn’t remember everything. It doesn’t explore all possibilities. It commits to what’s recently relevant . That trade-off is intentional. In systems where time matters, forgetting is not a bug. It’s a requirement. Takeaway The Sliding Window algorithm isn’t about subarrays or pointer tricks. It exists to preserve just enough context as time moves forward — preventing recomputation, stabilizing decisions, and keeping systems responsive without losing accuracy. That idea shows up everywhere data arrives continuously. And that’s why Sliding Window remains a core technique, not a coding shortcut.

Report Abuse bingkahu Posted on Jan 12 I let an AI with "20 years experience" architect my project and it was a disaster # opensource # programming # ai # github We’ve all seen the "AI is taking our jobs" posts. So, I decided to put it to the test. I found a "Senior AI Dev" (who claimed to have 20 years of experience in game dev and wikis) and let it take the wheel. The result? It spent 2 hours debugging a for loop that wasn't even broken. 📉 The "Expectation vs. Reality" Expectation: Clean, optimized, modular code. Reality: A chaotic mess of nested loops and the AI gaslighting me into thinking i++ was a security risk. 🛠️ How I actually fixed it (The Human Way) After the AI had its mid-life crisis, I actually had to get to work. I've been building out some projects on GitHub that (ironically) work way better than the "senior" advice I got today. If you want to see code that actually compiles without a 2-hour therapy session, check out what I'm working on: 👉 My GitHub: bingkahu Currently featured in my repos: Project 1: A 3D model of Ancient Baghdad with orbitcontrols. Project 2: An encrypted P2P messaging service that uses direct browser-to-browser communication, bypassing central servers for total privacy. Let's settle this: What’s the dumbest thing an AI (or a "Senior" dev) has ever told you? Let’s swap horror stories in the comments.

Report Abuse Labontese Posted on Jan 11 Building a Regulatory-Compliant Accessibility Scanner: From WCAG to Legal Compliance # webdev # react # a11y # typescript Building a Regulatory-Compliant Accessibility Scanner: From WCAG to Legal Compliance Most accessibility tools tell you what's wrong . But when regulators come knocking, they don't ask "Did you fix the color contrast?" — they ask "Are you compliant with EN 301 549 clause 9.1.4.3?" This guide walks you through three open-source packages I built to bridge that gap: from technical WCAG validation to legal compliance reporting, with ready-to-use React components that are accessible by default. The Problem We're Solving Here's a typical accessibility tool output: ❌ color-contrast: Elements must have sufficient color contrast ratio Expected: 4.5:1, Actual: 3.2:1 Enter fullscreen mode Exit fullscreen mode But here's what a compliance auditor needs: ❌ WCAG 2.1 Success Criterion 1.4.3 (Level AA) EN 301 549 Reference: 9.1.4.3 Swedish DOS-lagen: 12 § Lag (2018:1937) Risk Level: HIGH Remediation: Increase foreground/background contrast to minimum 4.5:1 Enter fullscreen mode Exit fullscreen mode Let's build this. The Three Packages Package Purpose npm @holmdigital/engine Accessibility scanner + CLI @holmdigital/standards Regulatory mapping database @holmdigital/components Accessible React components Part 1: The Quick Win — CLI Scanning Install and scan any website in seconds: npx hd-a11y-scan https://your-website.com --lang en --ci Enter fullscreen mode Exit fullscreen mode Output: 🔍 Scanning https://your-website.com... ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HolmDigital Regulatory Accessibility Report ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Score: 72/100 Violations: 4 critical, 8 serious, 12 moderate ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CRITICAL: Missing form labels ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📋 WCAG 2.1: 1.3.1 (Level A) 📋 EN 301 549: 9.1.3.1 📋 Section 508: 1194.22(n) ⚠️ Risk: CRITICAL 💡 Fix: Associate each input with a <label> element using the 'for' attribute matching the input's 'id'. 📍 Elements affected: - <input type="email" class="newsletter-input"> - <input type="text" class="search-box"> Enter fullscreen mode Exit fullscreen mode CLI Options # Generate PDF report npx hd-a11y-scan https://example.com --pdf report.pdf # Mobile viewport npx hd-a11y-scan https://example.com --viewport mobile # Swedish language output npx hd-a11y-scan https://example.com --lang sv # JSON for CI/CD pipelines npx hd-a11y-scan https://example.com --json > results.json Enter fullscreen mode Exit fullscreen mode Part 2: Programmatic Integration For deeper integration, use the scanner programmatically: import { RegulatoryScanner , setLanguage } from ' @holmdigital/engine ' ; // Set language context (affects rule descriptions) setLanguage ( ' en ' ); async function auditWebsite ( url : string ) { const scanner = new RegulatoryScanner ({ url , failOnCritical : true , // Throws if critical issues found viewport : { width : 1920 , height : 1080 } }); try { const result = await scanner . scan (); console . log ( ` ✅ Accessibility Score: ${ result . score } /100 📊 Total Issues: ${ result . violations . length } ⚠️ Critical: ${ result . violations . filter ( v => v . risk === ' critical ' ). length } ` ); // Group by WCAG criterion const byWcag = result . violations . reduce (( acc , v ) => { const key = v . wcagCriterion ; acc [ key ] = ( acc [ key ] || []). concat ( v ); return acc ; }, {}); return { score : result . score , byWcag }; } catch ( error ) { console . error ( ' Critical accessibility violations found! ' ); process . exit ( 1 ); } } // Usage auditWebsite ( ' https://your-site.com ' ); Enter fullscreen mode Exit fullscreen mode Real-World Example: GitHub Actions Integration name : Accessibility Audit on : pull_request : branches : [ main ] jobs : a11y-scan : runs-on : ubuntu-latest steps : - uses : actions/checkout@v4 - name : Setup Node uses : actions/setup-node@v4 with : node-version : ' 20' - name : Install & Build run : | npm ci npm run build npm run start & sleep 5 - name : Run Accessibility Scan run : npx hd-a11y-scan http://localhost:3000 --ci --lang en Enter fullscreen mode Exit fullscreen mode This fails the PR if any critical accessibility violations are found. Part 3: The Standards Database The real magic is in the regulatory mapping. Here's how it works under the hood: import { getEN301549Mapping , getRulesByLanguage } from ' @holmdigital/standards ' ; // Get the EN 301 549 mapping for a WCAG criterion const mapping = getEN301549Mapping ( ' 1.4.3 ' ); console . log ( mapping ); // { // wcagCriterion: '1.4.3', // wcagLevel: 'AA', // en301549Clause: '9.1.4.3', // description: 'Contrast (Minimum)', // risk: 'high', // remediation: { // description: 'Ensure text has a contrast ratio of at least 4.5:1', // technicalGuidance: 'Use CSS to adjust foreground or background colors...' // } // } // Get all rules for a specific language/region const swedenRules = getRulesByLanguage ( ' sv ' ); const usRules = getRulesByLanguage ( ' en-us ' ); // Each rule includes national law references console . log ( swedenRules [ 0 ]. nationalLaw ); // { // name: 'DOS-lagen', // reference: 'Lag (2018:1937) 12 §', // description: 'Lagen om tillgänglighet till digital offentlig service' // } Enter fullscreen mode Exit fullscreen mode Supported Regulations Language Regulation Coverage en EN 301 549, WCAG 2.1 EU Generic en-us Section 508, ADA United States en-ca AODA Canada en-gb PSBAR United Kingdom sv DOS-lagen Sweden de BITV 2.0 Germany fr RGAA France nl Digitoegankelijk Netherlands es UNE 139803 Spain Part 4: Accessible React Components Stop reinventing the wheel. These components handle ARIA, focus management, and keyboard navigation for you: import { Button , FormField , Dialog , Heading , SkipLink } from ' @holmdigital/components ' ; function ContactForm () { const [ isOpen , setIsOpen ] = useState ( false ); return ( <> { /* Skip link for keyboard users */ } < SkipLink href = "#main-content" > Skip to main content </ SkipLink > < main id = "main-content" > { /* Semantic headings with enforced hierarchy */ } < Heading level = { 1 } > Contact Us </ Heading > < form > { /* Auto-generated labels, error states, ARIA */ } < FormField label = "Email Address" type = "email" required autoComplete = "email" helpText = "We'll never share your email." error = { emailError } /> < FormField label = "Message" type = "textarea" required minLength = { 10 } /> { /* Accessible button with loading state */ } < Button variant = "primary" type = "submit" loading = { isSubmitting } > Send Message </ Button > </ form > { /* Focus-trapped modal dialog */ } < Dialog open = { isOpen } onClose = { () => setIsOpen ( false ) } title = "Message Sent" > < p > Thank you! We'll respond within 24 hours. </ p > < Button onClick = { () => setIsOpen ( false ) } > Close </ Button > </ Dialog > </ main > </> ); } Enter fullscreen mode Exit fullscreen mode What's Handled Automatically Feature Component WCAG Criterion Focus trapping Dialog , Modal 2.4.3 Escape to close Dialog , Modal 2.1.2 Label association FormField 1.3.1 Error announcement FormField 3.3.1 Heading hierarchy Heading 1.3.1 Skip navigation SkipLink 2.4.1 Visible focus All components 2.4.7 Color contrast All components 1.4.3 The Development Story Why I Built This I was working with a Swedish agency that needed to prove compliance with DOS-lagen (Sweden's digital accessibility law). Standard tools gave them WCAG violations, but auditors wanted EN 301 549 clause references with Swedish legal context. Existing solutions were either: Too technical (WCAG-only, no legal mapping) Too expensive (enterprise SaaS pricing) Too manual (consultants doing spreadsheet mappings) Architecture Decisions 1. Monorepo Structure packages/ ├── engine/ # Scanner + CLI (depends on standards) ├── standards/ # Regulatory database (no deps) └── components/ # React UI library (no deps) Enter fullscreen mode Exit fullscreen mode Each package is independently publishable but designed to work together. 2. Build Tooling We use tsup for building because: Single config for CJS, ESM, and DTS Fast builds (Rollup under the hood) Tree-shakeable output // tsup.config.ts export default { entry : [ ' src/index.ts ' ], format : [ ' cjs ' , ' esm ' ], dts : true , clean : true } Enter fullscreen mode Exit fullscreen mode 3. Exports Configuration A lesson learned the hard way — always put types first: { "exports" : { "." : { "types" : "./dist/index.d.ts" , "import" : "./dist/index.mjs" , "require" : "./dist/index.js" } } } Enter fullscreen mode Exit fullscreen mode If types comes after import , some bundlers won't find your TypeScript definitions. 4. i18n Architecture All user-facing strings are externalized: // src/i18n/index.ts import en from ' ../locales/en.json ' ; import sv from ' ../locales/sv.json ' ; // ... other locales let currentLang = ' en ' ; export function setLanguage ( lang : string ) { if ( locales [ lang ]) { currentLang = lang ; } } export function t ( key : string ): string { return locales [ currentLang ][ key ] ?? key ; } Enter fullscreen mode Exit fullscreen mode Getting Started Install # CLI scanning (no install needed) npx hd-a11y-scan https://your-site.com # For programmatic use npm install @holmdigital/engine # For React components npm install @holmdigital/components # For regulatory database only npm install @holmdigital/standards Enter fullscreen mode Exit fullscreen mode Quick Integration Checklist Add CI scanning to catch regressions Replace form components with accessible versions Add skip links for keyboard navigation Generate PDF reports for compliance documentation What's Next [ ] Browser extension for on-page scanning [ ] VS Code extension for inline warnings [ ] More national regulations (Australia, India, Japan) [ ] Automated fix suggestions with code generation Resources GitHub : github.com/holmdigital/a11y-hd NPM : @holmdigital/engine @holmdigital/standards @holmdigital/components Built with ❤️ by Holm Digital — Making accessibility compliance actually achievable.

Python Best Practices / Classes Code Formatting Code Testing Coding Style Comments Comprehensions Concurrency Conditionals Constants Dependency Management Distribution Docstrings Documentation Exception Handling Functions Generator Expressions Imports Logging Loops Object Mutability Optimization Project Layout Public API Surface Reference Python Glossary / mutable In Python, a mutable object allows you to modify its value in place without creating a new object. This characteristic is particularly useful when you need to make frequent changes to data, as it can improve performance by avoiding the overhead of creating new objects. Common mutable data types in Python include lists , dictionaries , and sets . When working with mutable objects, it’s important to be aware of the implications for your program. For example, if you pass a mutable object to a function, any changes made to the object within the function will affect the original object outside the function. This behavior can be advantageous and requires careful management to avoid unintended side effects. In contrast, an immutable object is an object whose state can’t be modified after it’s created. Example Here’s a quick example demonstrating the mutability of a list in Python: Python >>> numbers = [ 1 , 3 , 3 ] >>> numbers [ 1 ] = 2 >>> numbers [1, 2, 3] >>> numbers . append ( 4 ) >>> numbers [1, 2, 3, 4] In this example, you use an assignment to change the second value in the list. Then, you use the .append() method to modify the list by adding a new value, demonstrating the mutability of Python lists. Related Resources Tutorial Python's Mutable vs Immutable Types: What's the Difference? In this tutorial, you'll learn how Python mutable and immutable data types work internally and how you can take advantage of mutability or immutability to power your code. intermediate data-structures python For additional information on related topics, take a look at the following resources: Lists vs Tuples in Python (Tutorial) Python's list Data Type: A Deep Dive With Examples (Tutorial) Python's tuple Data Type: A Deep Dive With Examples (Tutorial) Strings and Character Data in Python (Tutorial) Differences Between Python's Mutable and Immutable Types (Course) Lists and Tuples in Python (Course) Lists vs Tuples in Python (Quiz) Exploring Python's list Data Type With Examples (Course) Exploring Python's tuple Data Type With Examples (Course) Strings and Character Data in Python (Course) Python Strings and Character Data (Quiz) By Leodanis Pozo Ramos • Updated Sept. 19, 2025 • Reviewed by Dan Bader Python Glossary Share Feedback Learn Python Start Here Learning Resources Code Mentor Python Reference Python Cheat Sheet Support Center Courses & Paths Learning Paths Quizzes & Exercises Browse Topics Live Courses Books Community Podcast Newsletter Community Chat Office Hours Learner Stories Membership Plans & Pricing Team Plans For Business For Schools Reviews Company About Us Team Mission & Values Editorial Guidelines Sponsorships Careers Press Kit Merch Privacy Policy ⋅ Terms of Use ⋅ Security ⋅ Contact Happy Pythoning! © 2012–2026 DevCademy Media Inc.

Report Abuse Sivaram Posted on Jan 13 Cowork: Claude Code for the Rest of Your Work # ai # software # productivity # tooling Anthropic just dropped something interesting, and it's not just another AI chatbot. It's called Cowork , and it might represent where AI agents are heading next. What is Cowork? Cowork is essentially "Claude Code for the rest of your work" — a general-purpose AI agent that can work with files on your computer without requiring you to write a single line of code. Think of it this way: Claude Code was built for developers to automate coding tasks. But Anthropic noticed something interesting — developers were using it for everything else: vacation research, building slide decks, cleaning up email, cancelling subscriptions, recovering wedding photos from hard drives, monitoring plant growth, and even controlling ovens. So they stripped away the terminal interface and built Cowork — a visual, approachable version that anyone can use. How It Works The workflow is refreshingly simple: Grant folder access — You give Claude access to a specific folder on your computer Describe what you need — Tell Claude what you want in plain language Let it work — Claude makes a plan, executes steps in parallel, and keeps you updated on progress Get results — Claude reads, edits, or creates files as needed Example Use Cases Here's what you can do with Cowork: Reorganize your downloads folder — Sort and rename files intelligently Create expense reports — Turn a pile of receipt screenshots into a structured spreadsheet Draft reports — Synthesize scattered notes into a coherent first draft File organization — Clean up your desktop or organize documents by project Real-World Performance: 320 Podcast Transcripts in 15 Minutes Lenny Rachitsky put Cowork to the test with a substantial task — analyzing 320 podcast transcripts to extract key insights. Here's what happened: The Task: "Go through every Lenny's Podcast episode and pull out the 10 most important themes and lessons for product builders. Then give me the 10 most counterintuitive truths." The Setup: Lenny gave Claude access to a folder containing 320 podcast transcripts. The Result: 15 minutes later, Claude delivered: The 10 Most Important Themes from Lenny's Podcast Activation Is Everything — Slack's "2,000 messages" moment, Gamma's 30-second magic. Get users to value fast. Storytelling as a Superpower — Compelling narratives align organizations better than documents. Positioning Is Strategy, Not Marketing — April Dunford's 5-step framework that starts with competitive alternatives, not messaging. Product Discovery Before Delivery — Teresa Torres' Opportunity Solution Trees and Marty Cagan's Four Risks framework. Talk to customers weekly, not quarterly. Ruthless Prioritization — Shreyas Doshi's LNO Framework (Leverage/Neutral/Overhead) and focusing on opportunity cost over ROI. AI is Transforming Product Development — Model maximalism, evals as core PM skill, CEOs becoming ICs again. Empowered Teams vs. Feature Factories — Marty Cagan's distinction: give teams problems to solve, not features to build. Build Your Operating System — Claire Hughes Johnson's framework for founding documents, operating cadence, and decision frameworks. Pre-Mortems and Risk Anticipation — Shreyas Doshi's technique to surface failure modes before they happen. Small Teams, Outsized Impact — Jason Fried's 2-person/6-week constraints, Shopify's pair programming culture. The 10 Most Counterintuitive Truths Fear Gives Bad Advice — Do the Opposite — Whatever you're afraid to do (hard conversation, telling board bad news) is exactly what you should do. Adding Friction Can INCREASE Conversion — Adding personalization questions to signup improved Amplitude's conversion by 5%. Fewer Features = More Value — The Walkman succeeded because Sony REMOVED recording. QuickBooks wins with half the features at double the price. Adding People Makes You Slower (Absolutely) — Companies produce MORE total output after layoffs. Coordination overhead is silent killer. What Customers Say They Want Is Meaningless — 93% said they wanted energy-efficient homes. Nobody bought them. "Bitchin' ain't switchin'." Goals Are Not Strategy — They're Opposite — Richard Rumelt says confusing goals for strategy is most common strategic error. OKRs are often just wish lists. Don't A/B Test Your Big Bets — Instagram and Airbnb actively reject testing for transformational changes. You can't A/B test your way to greatness. Your Gut IS Data — Intuition is compressed experiential learning that isn't statistically significant yet. Don't discount it. By the Time You're Thinking About Quitting, It's Too Late — Stewart Butterfield killed Glitch while it was still growing 6-7% weekly. That's why he could start Slack. Most PMs Are Overpaid and Unnecessary — Marty Cagan himself says feature teams don't need PMs. Nikita Bier calls PM "not real." Lenny's verdict: "This is a substantial task - 320 podcast transcripts to analyze!" That's impressive — processing 320 transcripts and synthesizing them into actionable insights in just 15 minutes. The Mind-Blowing Part Here's the detail that's getting attention: Cowork was reportedly built in about a week and a half, and much of it was written by Claude Code itself. That's right — Anthropic's AI coding agent helped build its own non-technical sibling product. It's a recursive improvement loop happening in real-time, and it shows how AI tools can accelerate their own development. Integration with Your Existing Tools Cowork doesn't work in isolation. It integrates with: Connectors — Link Claude to tools like Asana, Notion, Canva, Linear, and more Skills — Specialized capabilities for working with Excel, presentations, or following brand guidelines Chrome extension — Complete tasks that require browser access This means Claude can pull real data from your project management tools, generate documents in your preferred formats, and maintain context across your entire workflow. Safety First Anthropic is being upfront about the risks: Controlled access — Claude can only access files you explicitly grant it access to Confirmation prompts — Claude asks before taking significant actions Clear instructions matter — Vague prompts could lead to unintended actions (like deleting files) Prompt injection risks — Like all AI agents, there are concerns about malicious content trying to hijack the agent They recommend starting with non-sensitive files while you learn how it works. Availability Right now, Cowork is available as a research preview for: Claude Max subscribers ($100-$200/month) on macOS Waitlist available for users on other plans Windows support and broader availability are coming later. What This Means for the Future Cowork represents an interesting shift in AI — moving from chatbots that just talk to you, toward agents that can actually do things for you. It's not about replacing developers or knowledge workers; it's about giving them an AI collaborator that can handle the repetitive, time-consuming tasks that get in the way of real work. The fact that Claude Code helped build Cowork shows how AI tools can compound each other's capabilities. We're seeing the beginning of AI systems that can build, improve, and extend themselves. If you're on Claude Max with a Mac, you can try Cowork today by clicking "Cowork" in the Claude Desktop sidebar. Everyone else can join the waitlist and see what the future of AI-assisted work looks like.

Report Abuse Carlos Filho for AWS Community Builders Posted on Jun 10, 2024 Vídeo de apresentação e artigo do projeto de identificação facial com AWS Rekognition # aws # cloud # communitybuilder # architecture Hoje vou apresentar um projeto que envolve a implementação de pontos de identificação facial em 30 locais de monitoramento. Esse projeto será realizado utilizando diversos serviços da AWS para garantir segurança, eficiência e escalabilidade. Vamos começar com uma visão geral do projeto e, em seguida, detalhar cada componente da arquitetura. Descrição do projeto O projeto tem como objetivo implementar um sistema de reconhecimento facial para monitoramento em 30 locais diferentes. Estimamos que o sistema atenderá entre 2000 a 3000 pessoas. A arquitetura do sistema precisa ser robusta, segura e capaz de lidar com o grande volume de dados gerado. Para isso, utilizaremos uma combinação de serviços da AWS. Locais de monitoramento Cada um dos 30 locais de monitoramento será equipado com câmeras que capturam imagens faciais. Essas câmeras enviarão as imagens para um dispositivo de borda ou uma instância local que processará e encaminhará essas imagens para a AWS. Edge device/Instância local Os dispositivos de borda ou instâncias locais são responsáveis por receber as imagens das câmeras e enviá-las para a AWS. Essa conexão será feita de forma segura, utilizando AWS Direct Connect ou VPN para garantir que os dados sejam transmitidos com segurança e eficiência. Amazon S3 Uma vez que as imagens chegam à AWS, elas são armazenadas no Amazon S3. O Amazon S3 é um serviço de armazenamento altamente escalável e seguro, ideal para armazenar grandes volumes de dados, como as imagens capturadas. Além disso, o S3 permite que a gente configure notificações de eventos, que serão usadas para acionar outras partes do nosso sistema. AWS Lambda Quando uma nova imagem é carregada no Amazon S3, um evento é disparado para uma função AWS Lambda. O AWS Lambda é um serviço de computação serverless que permite executar código em resposta a eventos sem a necessidade de provisionar ou gerenciar servidores. O Lambda processa a imagem e a envia para o Amazon Rekognition para análise. Amazon Rekognition O Amazon Rekognition é um serviço de análise de imagens que utiliza aprendizado de máquina para realizar o reconhecimento facial. Ele compara a imagem recebida com as fotos armazenadas no nosso banco de dados e retorna os resultados. Esse processo é rápido e altamente preciso, garantindo que as identificações sejam feitas corretamente. Amazon RDS Os resultados do Amazon Rekognition, juntamente com as informações pessoais e fotos das pessoas, são armazenados no Amazon RDS. O Amazon RDS é um serviço de banco de dados relacional gerenciado que facilita a configuração, operação e escalabilidade de um banco de dados na nuvem. Ele oferece alta disponibilidade e segurança para os nossos dados. Amazon API Gateway Para permitir que os dispositivos locais consultem os resultados do reconhecimento facial, utilizamos o Amazon API Gateway. O API Gateway facilita a criação, publicação, manutenção, monitoramento e proteção de APIs em escala. Ele expõe endpoints que os dispositivos locais podem usar para obter informações do sistema. AWS CloudWatch Finalmente, utilizamos o AWS CloudWatch para monitorar todos os serviços e garantir que o sistema esteja funcionando corretamente. O CloudWatch coleta métricas e logs, permitindo que configuremos alertas e tomemos ações proativas em caso de problemas. Sincronização de dados Para garantir que os dados estejam sempre atualizados, utilizamos o AWS Database Migration Service (DMS) para sincronizar o Amazon RDS com o banco de dados local. Isso assegura que quaisquer mudanças feitas no banco de dados local sejam refletidas no RDS e vice-versa, mantendo a integridade e a consistência dos dados. Desenho da arquitetura Agora, vamos ver como todos esses componentes se conectam em um diagrama de arquitetura. Câmeras nos locais de monitoramento capturam imagens faciais. As imagens são enviadas para os dispositivos de borda ou instâncias locais. Esses dispositivos transmitem as imagens para o Amazon S3 através de uma conexão segura (Direct Connect ou VPN). Amazon S3 armazena as imagens e dispara eventos para o AWS Lambda. AWS Lambda processará as imagens e as envia para o Amazon Rekognition. Amazon Rekognition realizará o reconhecimento facial e compara as imagens com o banco de dados no Amazon RDS. AWS Lambda atualizará os resultados no Amazon RDS e fornece os resultados para o Amazon API Gateway. Os dispositivos locais podem consultar os resultados através do Amazon API Gateway. AWS DMS sincronizará o Amazon RDS com o banco de dados local, garantindo que os dados estejam sempre atualizados. AWS CloudWatch monitorará todos os serviços, garantindo a integridade e a performance do sistema. Conclusão E assim, temos um sistema completo de reconhecimento facial utilizando os serviços da AWS. Essa arquitetura garante segurança, escalabilidade e eficiência, atendendo às necessidades do cliente para monitoramento em múltiplos locais.

Report Abuse Gabor Szabo Posted on Nov 28, 2022 • Originally published at code-maven.com Why use a version control system? - 💒 # git # beginners # programming # tutorial git-on-windows (2 Part Series) 1 Why use a version control system? - 💒 2 Download and install git on Linux, Windows, and macOS Most people will save versions of whatever they are working on. For example if they work on a file called wedding_vows.doc at one point they might save it as wedding_vows_1.doc 💒 and then when they get divorced and marry again they might update the original file and now create a copy called wedding_vows_2.doc 💒💒. Then they go on and might have wedding_vows_3.doc etc. If they have multiple files then maybe the create a copy of all the files and put them in directories called " wedding_1 " and " wedding_2 ". Some other people, instead of numbering the versions they attach the current date to it. So they would have a file called wedding_vows_2013_01_07.doc or a folder called wedding_2013_01_07 that also has all the pictures from the wedding. They basically create a home-made, manual version control system. If you are writing an application then usually you'll have a lot more files and you'll have a lot more versions. Then this home-made version control can easily get out of control. Why reinvent the wheel if there are already excellent open source version control systems? Such as git? Advantages of having a Version Control System (VCS) There are a number of advantages using a well-known VCS. One of them is that if you'd like someone else to start working on your project you don't need to teach them about your own VCS. Most likely they already know how to use it. Fearless experimentation If you are a chemist and you combine two materials, in most cases you cannot go back and separate them again. If you are doctor and cut of a part of a patient in the hope that it will solve the problem the patient has, you cannot go back. You cannot undo it. In programming if you overwrite a file with some changes your editor might have an undo functionality, but it is usually very limited in its history. Using a version control system a programmer could do any experiment and safely know that s/he can go back to an earlier state, an earlier version of the code. Fearless deletion In many cases I see people keep around old code saying: ok maybe we'll need it at some point. Currently we are not using this code but maybe some day need to copy-paste from it or maybe literally we'll need to use it, so we don't delete it. Then you accumulate a lot of, well, basically garbage. Code that's not used that not only takes up space and compilation time, but take up a lot of brain cycles (mental energy) when someone actually read you code an encounters this function and tries to understand it. The person might spend a lot of time trying to figure out what does this function do till they realize that the function is not in use. Or maybe it is in use by something else which is not in use. So it can get complicated. If you have a version control system like git or some other version control system then you can just delete this code, commit your changes to your version control system and at any point of time when you need it you can go back this version, look at it copy from it pieces, or just bring back the whole piece of code in case you now need it. Easier (smoother) collaboration Another thing is the easier and quite smooth collaboration with other people. As long as you work alone you don't need collaboration, of course, but once you do collaborate, having a version control system is extremely important. Let's go back to the example without version control system. You have a file. You make some changes. Another person has the same file. That person also makes some changes. How can you now combine (merge together) the two changes? How can you make sure that the changes of both of you are kept? In many organization there is a shared disk and people take files from there and save it back. What if two people try to edit the file at the same file? Either the system limits that only one person can open the file at one time, but that means people have to wait one for the other. Or if there is no locking then if both edit and save the file then the second one wins. All the changes made by the person who saved first will be lost. Having a version control system can make this really smooth Of course it is not perfect and there still might be some issue. The people still have to talk to each other, but in many cases it makes it a lot smoother to collaborate with other people. Even if they are in different time-zones, different locations History One of the basic thing is that you can easily look at the history of your code base. What changed were made, if there multiple people contributing to the source code then who made the changes. If you are keeping a good track of why you made the change, so every time when you make a change you have some explanation why did you do that then it's a gold mine. Actually I rarely need to look at the history, but when you do, it's extremely important, it is extremely valuable that you can look at the history. It is a little-bit like backups. You really rarely need to have backups when you do, if you don't have it then it is a really big issue. So this is more or less similar to history although we'll look a lot more at the history just because we all kinds of small mistakes. So for example, one of the mistakes that we can easily make: You have some working code and then you make some changes, other people make some changes and check the parts that you changes. Two weeks later someone reports that some feature stopped working. They know it used to work. You remember it used to work, but you see that it does not work now. You may remember that it worked two weeks ago. How can you find out what happened? Which change broke it? Version control systems in general and git specifically have tools for it, but without having this history we really can't do anything. Having the history you'll be able to track down which change caused this error? Why was that change made? Usually these changes are made for some good purpose, but maybe they have some side-effects. You will have to understand that and not just revert the change, because that will break something else. Which Version Control System (VCS)? Finally, just to get to end of the slide, there are bunch of version control systems. Some of them are proprietary so you have to buy them, many of them are open source. There is a list of them on the slide: git, mercurial (hg), subversion (svn), cvs, rcs, ... that's just going back in history. The most popular these days is git. Most popular by far. It is a distributed version control system, it was created by Linus Torvalds the same person who created the Linux Operating System (actually the Linux kernel), It is used by almost everyone. Both Open Source and corporate. So that's what you are going to learn later on in this course. This is part of a series I am going to publish in the coming days.

This is independent of whether the document is being backed up by the included Time Machine or third-party backup software. Unfortunately not all apps use this facility, and it doesn’t account for reverting related and interdependent files together, to say nothing of fancier features like branching, tagging, or collaboration with others on the same document. But it’s nice and can help keep you from cluttering your storage with Wedding Vows , Wedding Vows 1 , Wedding Vows 2 , Wedding Vows final , Wedding Vows final FINAL , etc. Like comment: Like comment: 2 likes Like Comment button Reply Collapse Expand Gabor Szabo Gabor Szabo Gabor Szabo Follow Helping individuals and teams improve their software development practices.

I was disappointed that I had to use the separate rcs command on Unix to achieve similar results. The nice thing about macOS persistent versioned documents is they use Core Data , so they’re structured as an object graph rather than a text stream and individual entities’ attributes can be diffed, merged, and synced.

K SDKs Blog GitHub English Português 日本語 한국어 API Documentation Support Home Introduction ATProto Ethos SDKs Glossary FAQ Building apps Quick start Cookbook ⧉ Distributed Systems Guides Overview Identity Data Repositories Schemas & Lexicon Lexicon Style Guide PDS Self-Hosting Going to production OAuth Introduction Permission Requests Account Migration Specs AT Protocol Data Model Lexicon Cryptography Accounts Repository Blobs Labels HTTP API (XRPC) OAuth Permissions Event Stream Sync DID Handle NSID TID Record Key URI Scheme Namespaced Identifiers (NSIDs) Namespaced Identifiers (NSIDs) are used to reference Lexicon schemas for records, XRPC endpoints, and more. The basic structure and semantics of an NSID are a fully-qualified hostname in Reverse Domain-Name Order, followed by a simple name. The hostname part is the domain authority, and the final segment is the name . NSID Syntax Lexicon string type: nsid The domain authority part of an NSID must be a valid handle with the order of segments reversed. That is followed by a name segment which must be an ASCII camel-case string. For example, com.example.fooBar is a syntactically valid NSID, where com.example is the domain authority, and fooBar is the name segment. The comprehensive list of syntax rules is: Overall NSID: must contain only ASCII characters separate the domain authority and the name by an ASCII period character ( . ) must have at least 3 segments can have a maximum total length of 317 characters Domain authority: made of segments separated by periods ( . ) at most 253 characters (including periods), and must contain at least two segments each segment must have at least 1 and at most 63 characters (not including any periods) the allowed characters are ASCII letters ( a-z ), digits ( 0-9 ), and hyphens ( - ) segments can not start or end with a hyphen the first segment (the top-level domain) can not start with a numeric digit the domain authority is not case-sensitive, and should be normalized to lowercase (that is, normalize ASCII A-Z to a-z ) Name: must have at least 1 and at most 63 characters the allowed characters are ASCII letters and digits only ( A-Z , a-z , 0-9 ) hyphens are not allowed the first character can not be a digit case-sensitive and should not be normalized A reference regex for NSID is: /^[a-zA-Z]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(\.[a-zA-Z0-9]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)+(\.[a-zA-Z]([a-zA-Z0-9]{0,62})?)$/ Copy Copied! NSID Syntax Variations When referring to a group or pattern of NSIDs, a trailing ASCII star character ( * ) can be used as a "glob" character. For example, com.atproto.* would refer to any NSIDs under the atproto.com domain authority, including nested sub-domains (sub-authorities). A free-standing * would match all NSIDs from all authorities. Currently, there may be only a single star character; it must be the last character; and it must be at a segment boundary (no partial matching of segment names). This means the start character must be proceeded by a period, or be a bare star matching all NSIDs. Examples Syntactically valid NSIDs: com.example.fooBar net.users.bob.ping a-0.b-1.c a.b.c com.example.fooBarV2 cn.8.lex.stuff Copy Copied! Invalid NSIDs: com.exa💩ple.thing com.example com.example.3 Copy Copied! Usage and Implementation Guidelines A strongly-encouraged best practice is to use authority domains with only ASCII alphabetic characters (that is, no digits or hyphens). This makes it significantly easier to generate client libraries in most programming languages. The overall NSID is case-sensitive for display, storage, and validation. However, having multiple NSIDs that differ only by casing is not allowed. Namespace authorities are responsible for preventing duplication and confusion. Implementations should not force-lowercase NSIDs. It is common to use "subdomains" as part of the "domain authority" to organize related NSIDs. For example, the NSID com.atproto.sync.getHead uses the sync segment. Note that this requires control of the full domain sync.atproto.com , in addition to the domain atproto.com . Lexicon language documentation will provide style guidelines on choosing and organizing NSIDs for both record types and XRPC methods. In short, records are usually single nouns, not pluralized. XRPC methods are usually in "verbNoun" form. Interop test vectors are available from the atproto-interop-tests repository. Possible Future Changes It is conceivable that NSID syntax would be relaxed to allow Unicode characters in the final segment. The "glob" syntax variation may be modified to extended to make the distinction between single-level and nested matching more explicit. No automated mechanism for verifying control of a "domain authority" currently exists. Also, not automated mechanism exists for fetching a lexicon schema for a given NSID, or for enumerating all NSIDs for a base domain. Previous Handle Next TID © Copyright 2026 . All rights reserved.

Report Abuse Ceora Ford for CodeSandbox Posted on May 13, 2021 • Originally published at codesandbox.io How to Maintain Your Skills as a Developer # career # webdev # productivity It’s no secret that the tech industry is always changing. New frameworks are always emerging and new features are constantly being added to the languages and frameworks that already exist. This can be exciting but sometimes it can be hard to keep up. Some people work in environments that don’t welcome change. Not everyone’s team is looking to implement the latest innovation. Zachariah, CEO and CTO of SquadCast , had this experience. In episode 3 of the Version One podcast , he talked about an experience he had early on in his career. He was in a position that didn’t allow for much growth. So how was he able to keep his coding skills up to par? So what I did was I used that time to contribute to open source projects, research, sharpen my skills, [to] kind of stay sharp. As Zachariah mentioned, there are many things you can do to stay sharp. This post will explain 5 ways you can maintain and grow your coding skills. Read other people's code When it comes to getting better at a certain coding language or framework, we usually think that we need to work on some fancy, new project. While that isn't a bad idea, reading other people's code is another very helpful step. Reading other people's code can often be overlooked but it's a great way to familiarize yourself with new and old syntax and to test your ability to understand unfamiliar codebases. Where can you find projects to read through? A great place to start is GitHub. Check out your favorite open source projects and products. Casually read through the code and see what you can learn. Is there a feature that you're curious about? Try to find out how it was implemented. You can also search for projects by language. If there is a language you want to brush up on, you can check out some of the most popular Work on top of already existing code Work on existing projects. You can find your own projects and iterate on them, adding new features or changing the structure of your code. You can also search for open source projects on GitHub. Find a project that's in a language you would like to brush up on and find an issue you can tackle. If you're not quite comfortable with making open source contributions, you can either stick to your own existing projects or read this helpful, step-by-step guide . Working on existing code is great because it presents new challenges. You have to figure out code that may be deprecated or hard to understand, even if it’s your project. By doing this, you'll train yourself to navigate unfamiliar codebases. This is a very valuable skill to gain since oftentimes in professional settings, you’ll have to add to code that already exists instead of starting something from scratch. Watch other people code Watch other people code on platforms like YouTube and Twitch. Through videos and live streams, you can see other developers code and problem solve out loud. You can follow their thought pattern and see how they fix and tackle bugs and other problems in their code. There’s so much you can gain from watching this process. You can learn new syntax, learn how to approach and solve problems, and learn how to implement new features. Do coding challenges Try completing coding challenges and exercises. There are tons of websites out there like HackerRank and CodeWars that present problems that you have to solve with your code stack of choice. These challenges are made to be short and to the point while also forcing you to solve complex problems. They’re a great way to stay sharp and keep up with any language. Read articles about code There are tons of developer blogs out there. Developer blogs are full of gems. There’s so much you can learn from reading articles. If there’s a topic you want to learn more about, do a quick Google search or search on sites like dev.to for articles that can help. Reading articles written by other developers is another way to see how other people think and problem solve. As mentioned earlier, this is invaluable and can add to your skills and knowledge. So when you come across an article that covers a topic you’re interested in, take the time to read through it. And make note of any points that stood out to you. Conclusion Tech moves fast but even so, growth can sometimes feel stagnant. If you feel like you’re at a standstill, try these tips. By doing these things, you’ll be able to stay sharp and grow your skills. There’s still more you can learn from Zachariah and his journey to becoming a CEO and CTO of SquadCast.

exception handling functions generator expressions imports logging loops object mutability optimization project layout public API surface Reference Python Glossary / slicing In Python, slicing is an operation that allows you to extract portions of sequences like lists , tuples , and strings by specifying a start , stop , and step indices with the syntax sequence[start:stop:step] . In this syntax, start is the index where the slice begins, stop is the index where the slice ends (exclusive), and step determines the stride between each element in the slice. If you omit start , stop , or step , then they default to the beginning of the sequence, the end of the sequence, and a step of one, respectively. With slicing, you can quickly obtain a subset of items without modifying the original sequence, making it an essential feature for any Python programmer. Example Here’s a quick example of how you can use slicing with a list: Python >>> numbers = [ 0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ] >>> # Get a slice of numbers from index 2 to 5 >>> numbers [ 2 : 6 ] [2, 3, 4, 5] >>> # Get every other element from the list >>> numbers [:: 2 ] [0, 2, 4, 6, 8] Related Resources Tutorial Python's list Data Type: A Deep Dive With Examples In this tutorial, you'll dive deep into Python's lists. You'll learn how to create them, update their content, populate and grow them, and more. Along the way, you'll code practical examples that will help you strengthen your skills with this fundamental data type in Python. intermediate data-structures python For additional information on related topics, take a look at the following resources: Python's tuple Data Type: A Deep Dive With Examples (Tutorial) Lists vs Tuples in Python (Tutorial) Strings and Character Data in Python (Tutorial) Exploring Python's list Data Type With Examples (Course) Exploring Python's tuple Data Type With Examples (Course) Lists and Tuples in Python (Course) Lists vs Tuples in Python (Quiz) Strings and Character Data in Python (Course) Python Strings and Character Data (Quiz) By Leodanis Pozo Ramos • Updated June 3, 2025 Python Glossary Share Feedback Learn Python Start Here Learning Resources Code Mentor Python Reference Python Cheat Sheet Support Center Courses & Paths Learning Paths Quizzes & Exercises Browse Topics Live Courses Books Community Podcast Newsletter Community Chat Office Hours Learner Stories Membership Plans & Pricing Team Plans For Business For Schools Reviews Company About Us Team Mission & Values Editorial Guidelines Sponsorships Careers Press Kit Merch Privacy Policy ⋅ Terms of Use ⋅ Security ⋅ Contact Happy Pythoning! © 2012–2026 DevCademy Media Inc.

exception handling functions generator expressions imports logging loops object mutability optimization project layout public API surface Reference Python Glossary / indexing In Python, indexing is an operation that allows you to access individual items within a sequence , such as a list , tuple , or string , using integer indices and the syntax sequence[index] . Python uses zero-based indexing, meaning that the first item of a sequence has an index of 0 , the second item has an index of 1 , and so on. You can also use negative indices to access items from the end of a sequence, with -1 referring to the last item. Indexing allows you to retrieve specific items from a sequence. In mutable sequences like lists, it also allows you to modify or delete items. Example Here’s a quick example of how you can use indexing in a list: Python >>> fruits = [ "apple" , "banana" , "cherry" ] >>> # Accessing items by positive index >>> fruits [ 0 ] 'apple' >>> fruits [ 1 ] 'banana' >>> # Accessing items by negative index >>> fruits [ - 1 ] 'cherry' >>> fruits [ - 2 ] 'banana' >>> # Modifying and deleting items >>> fruits [ 2 ] = "orange" >>> fruits ['apple', 'banana', 'orange'] >>> del fruits [ 0 ] >>> fruits ['banana', 'orange'] Related Resources Tutorial Python's list Data Type: A Deep Dive With Examples In this tutorial, you'll dive deep into Python's lists.

Report Abuse wellallyTech Posted on Jan 9 • Originally published at wellally.tech Accessible Visuals: How Inclusive Charts Empower Patient Health # frontend # react # a11y # healthtech In the world of health technology, data visualizations are essential tools for clarity. They translate complex biometrics—like heart rate trends or sleep cycles—into manageable insights that empower us to take action. However, when these dashboards are not designed for accessibility, we inadvertently create barriers for users with disabilities. Ensuring your data is readable for everyone is the first step toward a more inclusive understanding of your results . The Hidden Barrier in Health Dashboards Many health tech platforms rely heavily on "visual-first" designs that can exclude those using screen readers or living with color vision deficiencies. A standard chart often appears as a "black box" to assistive technology if it lacks proper semantic markers. Research suggests that accessible design is not just a compliance requirement; it is associated with better health literacy. When data is structured correctly, every user can interpret their health trends regardless of how they interact with the screen. Moving Beyond Color-Only Data A common pitfall in health apps is using color as the only way to convey meaning—such as red for "high risk" or green for "optimal." For many, these distinctions are invisible. To solve this, developers are encouraged to use patterns and textures to differentiate data points. For example, a striped bar vs. a solid bar ensures that information remains clear even in grayscale or high-contrast modes. Navigating with Intention Interactive charts should be fully navigable via keyboard, not just a mouse. By implementing tabIndex and custom keyboard hooks, users can "tab" through their health metrics one by one. This level of control allows for a focused review of specific data points, such as a single day's step count. This structured approach is often suggested for reducing "information overload" during health tracking. Quick Checklist: Is Your Health Chart Accessible? Feature Requirement Purpose ARIA Roles role="img" or role="listitem" Narrates data to screen readers. Contrast Minimum 3:1 ratio Ensures visibility for low-vision users. Labels aria-label for every data point Provides context for specific values. Keyboard Full Arrow Key support Allows navigation without a mouse. Conclusion: Building for Every User Creating accessible health visualizations is a commitment to ethical design. By focusing on semantic code, keyboard navigation, and color independence, we ensure that health data remains a tool for empowerment rather than a source of frustration. 3 Key Takeaways: Semantics Matter : Use ARIA roles to describe the "story" the chart is telling. Go Beyond Color : Use shapes or patterns to define different health metrics. Ensure Keyboard Focus : Every interactive data point must be reachable via the "Tab" key.

Report Abuse Shada Daab Posted on Nov 8, 2025 Understanding Model Context Protocol (MCP) Servers # ai # api # architecture Model Context Protocol (MCP) is a new open standard (introduced by Anthropic in late 2024) that unifies how AI systems like large language models (LLMs) connect to external tools, data, and services. In MCP’s client-server architecture, an AI host (for example, a chat app or IDE) runs one or more MCP clients, each of which connects to an MCP server that provides specific functionality. An MCP server is simply a program (often a Node/TypeScript/Express service for JS developers) that registers “tools” and “resources” that the AI can invoke . These tools might let the AI read files, query a database, call an API, or perform any domain-specific action. Each action is mediated by the MCP protocol (a JSON-RPC 2.0–based interface over stdio or HTTP/SSE) so that the AI and server communicate in a standardized way . MCP Architecture – an AI host on the user’s device runs one or more MCP clients, each connected to an MCP server. The server implements tools (functions) or data queries, often calling external APIs, and responds over the MCP protocol This model solves the “N×M” connector problem: before MCP, developers had to write custom bridge code for each AI-tool pair, leading to many one-off integrations. MCP provides a universal interface for the AI to discover and use tools . In practice, popular AI platforms (ChatGPT, Claude, etc.) and agent frameworks create an MCP client under the hood, so your JavaScript code can focus on exposing tools or calling them without worrying about AI prompts. Why Use MCP Servers? (Benefits & Use Cases) Standardized integrations. MCP is an open, vendor-neutral protocol (similar in spirit to OpenAPI but for AI tools.). It lets any AI client talk to any MCP server with no proprietary plumbing. Anthropic’s docs note that MCP ships with SDKs in many languages (TypeScript, Python, C#, Java, etc.) and reference implementations for GitHub, Slack, Google Drive, databases, browser automation, and more. This ecosystem means you can often reuse or adapt an existing MCP server rather than reinvent one from scratch. Secure, user-mediated access. By design, MCP interactions require explicit user approval. For local servers, the AI must ask the user before performing any action, ensuring you stay in control. For remote servers, MCP supports standard OAuth flows so end users can grant limited access tokens without sharing credentials. This combination of explicit approval and scoped tokens helps mitigate risks – for example, Cloudflare’s blog notes that MCP “uses OAuth” under the hood so users grant access safely. Immediate new capabilities for AI. Connecting an MCP server can dramatically boost an AI’s abilities. For instance, an MCP server exposing your database enables natural-language queries to that database (use cases like “AI2SQL”). In software development, MCP is already powering code-assistant tools: IDEs like VS Code, GitHub Copilot, and platforms like Replit or Sourcegraph connect MCP servers that let the AI read your codebase, search your repo, or manipulate files in real-time. In short, you can turn your AI assistant into an agent that takes actions (sending emails, updating spreadsheets, deploying code, etc.) instead of just answering questions. Wide adoption and momentum. Major AI providers (OpenAI, Google DeepMind, Microsoft) have embraced MCP. For example, in 2025 OpenAI announced MCP support in ChatGPT and their Agents SDK, and Google confirmed MCP support in its Gemini models. This broad industry adoption means MCP is likely to be supported everywhere agents run, so building on it is future-friendly. (One reporter even called MCP the “USB-C for AI” uniting rivals.) Customizable to your needs. Because the protocol is open-source and extensible, you can write your own MCP server in JavaScript to connect any data source or tool to AI. This is huge for specialized domains: for example, you could build an MCP server that interfaces with your company’s ERP system or a proprietary API, without having to wait for a vendor plugin.

A space to share projects, ask questions, and discuss server-driven templating Dropdown menu Dropdown menu Skip to content Navigation menu Search Powered by Algolia Search Log in Create account Design Community Close Privacy Policy Last Updated: September 01, 2023 This Privacy Policy is designed to help you understand how DEV Community Inc. (" 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.

If you have questions about our automated decision making, you may contact us as set forth in the "Contact Us" section below. De-identified and Aggregated Information .

YOUR PRIVACY CHOICES AND RIGHTS Your Privacy Choices . The privacy choices you may have about your personal information are determined by applicable law and are described below. Email Communications . If you receive an unwanted email from us, you can use the unsubscribe link found at the bottom of the email to opt out of receiving future emails. Note that you will continue to receive transaction-related emails regarding products or Services you have requested.

In accordance with applicable law, you may have the right to: Access Personal Information about you, including: (i) confirming whether we are processing your personal information; (ii) obtaining access to or a copy of your personal information; Request Correction of your personal information where it is inaccurate, incomplete or outdated.

INTERNATIONAL DATA TRANSFERS All information processed by us may be transferred, processed, and stored anywhere in the world, including, but not limited to, the United States or other countries, which may have data protection laws that are different from the laws where you live. We always strive to safeguard your information consistent with the requirements of applicable laws. 7. RETENTION OF PERSONAL INFORMATION We store the personal information we collect as described in this Privacy Policy for as long as you use our Services or as necessary: to fulfill the purpose or purposes for which it was collected, to provide our Services, to resolve disputes, to establish legal defenses, to conduct audits, to pursue legitimate business purposes, to enforce our agreements, and to comply with applicable laws. 8. SUPPLEMENTAL DISCLOSURES FOR CALIFORNIA RESIDENTS Refer-a-Friend and Similar Incentive Programs . As described above in the How We Use Your Personal Information section ("Share Content with Friends or Colleagues" subsection), we may offer referral programs or other incentivized data collection programs. For example, we may offer incentives to you such as discounts or promotional items or credit in connection with these programs, wherein you provide your personal information in exchange for a reward, or provide personal information regarding your friends or colleagues (such as their email address) and receive rewards when they sign up to use our Services. (The referred party may also receive rewards for signing up via your referral.) These programs are entirely voluntary and allow us to grow our business and provide additional benefits to you. The value of your data to us depends on how you ultimately use our Services, whereas the value of the referred party's data to us depends on whether the referred party ultimately becomes a User or Forem Operator and uses our Services. Said value will be reflected in the incentive offered in connection with each program. Accessibility . This Privacy Policy uses industry-standard technologies and was developed in line with the World Wide Web Consortium's Web Content Accessibility Guidelines, version 2.1* . * If you wish to print this policy, please do so from your web browser or by saving the page as a PDF.

The California "Shine the Light" law permits users who are California residents to request and obtain from us once a year, free of charge, a list of the third parties to whom we have disclosed their personal information (if any) for their direct marketing purposes in the prior calendar year, as well as the type of personal information disclosed to those parties. Right for Minors to Remove Posted Content . Where required by law, California residents under the age of 18 may request to have their posted content or information removed from the publicly-viewable portions of the Services by contacting us directly as set forth in the "Contact Us" section below or by logging into their account and removing the content or information using our self-service tools. 9. SUPPLEMENTAL NOTICE FOR NEVADA RESIDENTS If you are a resident of Nevada, you have the right to opt-out of the sale of certain Personal Information to third parties who intend to license or sell that Personal Information. You can exercise this right by contacting us as set forth in the "Contact Us\" section below with the subject line "Nevada Do Not Sell Request" and providing us with your name and the email address associated with your account.

View page as Markdown In this article Working with pull requests Draft pull requests Differences between commits on compare and pull request pages Further reading Pull requests are proposals to merge code changes into a project. A pull request is GitHub's foundational collaboration feature , letting you discuss and review changes before merging them. This helps teams work together, catch issues early, and maintain code quality. View your pull requests Working with pull requests The Conversation tab of a pull request displays a description of the changes, a timeline of events, and comments and reviews from collaborators. This central hub lets you track the discussion and progress of the proposed changes. The Commits tab shows all commits made to the pull request branch in chronological order. This helps you understand the development history and see how the changes evolved over time. The Checks tab displays the status of any automated tests, builds, or other continuous integration workflows that run when you push commits. These checks help ensure your changes meet quality standards before merging. The Files changed tab shows the differences between the proposed changes and the existing code, making it easy to see what will change when the pull request merges. Draft pull requests When you create a pull request, you can choose to make it a draft pull request. Draft pull requests cannot be merged, and code owners are not automatically requested to review them. This is useful when you want to share work-in-progress without formally requesting reviews. When you're ready to get feedback on your pull request, you can mark your draft pull request as ready for review. Marking a pull request as ready for review will request reviews from any code owners. You can convert a pull request to a draft at any time. See Changing the stage of a pull request . Differences between commits on compare and pull request pages The compare and pull request pages use different methods to calculate the diff for changed files: Compare pages show the diff between the tip of the head ref and the current common ancestor (that is, the merge base) of the head and base ref. Pull request pages show the diff between the tip of the head ref and the common ancestor of the head and base ref at the time when the pull request was created. As a result, the merge base used for the comparison might be different.

While there is nuance as far as what it means for a post to be assisted by AI, we care most that the author of the post is able to stand by the information they are sharing. We encourage the use of AI experimentation with the appropriate disclosure, while wholly discouraging the use of these tools to prolifically generate content which has not been scrutinized prior to publication. The DEV Community Guidelines for AI-Assisted and -Generated Articles AI-assisted and -generated articles are allowed on DEV Community, so long as they follow these guidelines: AI-assisted and -generated articles should… Be created and published in good faith , meaning with honest, sincere, and harmless intentions. Disclose the fact that they were generated or assisted by AI in the post, either upfront using the tag #ABotWroteThis or at any point in the article’s copy (including right at the end). - For example, a conclusion that states “Surprise, this article was generated by ChatGPT!” or the disclaimer “This article was created with the help of AI” would be appropriate. Ideally add something to the conversation regarding AI and its capabilities. Tell us your story of using the tool to create content, and why! Be checked for factual accuracy before publishing. (This guideline was suggested by @chihuahuaux via Twitter . Thanks!) AI-assisted and -generated articles should not… Promote any business, program, or course (including your own). Be published with the intent to confuse , deceive , or bamboozle its readers. Be published with the main purpose of building a personal brand, building a social media presence, or gaining clout. Contain educational content or information generated by AI because you, the human author, did not already know it to some degree. AI is great for assistance with English syntax for a variety of reasons, but if you don’t already know or understand the concept you’re writing about, please do not rely on the machine to “know” it for you. Commenting Guidelines In order to support a strong sense of human community on the site, we ask that you not use bots or AI to generate comments on posts, whether the post was published by you or another community member. The exceptions to this rule are basic translation and grammar/syntax improvement tools, such as Google Translate, Grammarly, or any tool used for Assistive Technology (AT) purposes. If you notice a mistake or bad practice in a post that is disclosed to be AI-generated or -assisted, we encourage you to call it out (kindly, of course!). The following actions may result in suspension or a ban: Publishing any article with the intent to harm or scam its readers. Publishing any article with the main purpose of soliciting money. Publishing any article with the main purpose of building backlinks to increase the search engine optimization (SEO) of another site. The two exceptions to this are: (1) a backlink to a personal blog, or (2) a backlink to a company blog IF the article has been shared under that company’s organization on DEV. Publishing any article that is directly plagiarized, knowingly or unknowingly . Our guidelines may continue to evolve and are open for scrutiny. At the end of the day, we expect good faith community activity, and that all authors are able to stand behind the purpose and accuracy of their content. How to Report Offending Content We ask that you DO NOT publicly confront or question members for creating content that you believe to be written with AI assistance but not following our guidelines. Doing so, may result in us warning or suspending your DEV account. Instead, when you come across offending posts, we ask that you please report them via our abuse report from here . When you report offenders, provide details about why you believe they are violating our guidelines. For instance, you can tell us how you came to the conclusion you did (i.e. you ran their work through https://www.zerogpt.com/ and it said the likelihood of the post being generated by ChatGPT is 95%) — we will take all information provided into account. As for offenders, we will decide the severity of the offense, what disciplinary action is necessary (if any), and how to remediate the issue. We have ways of lowering visibility on posts if needed and can add #abotwrotethis to someone's post as well if they refuse to add the necessary disclosure. We also have the ability to lower the visibility of all of someone's posts if they make a habit of regularly posting works that disobey our guidelines. We also offer the ability for community members to block other community members. So, if you have reported someone who you believe to be regularly violating our AI Guidelines, you can go ahead and take action to block them so that you won't see their writing in your fee anymore. To do so, just navigate to the user's profile page and click on the ... menu in the corner, then select block. Thank you! If you have questions or feedback about our approach, we encourage you to contact us via support@dev.to . If you believe that someone isn't following these guidelines, please don't hesitate to report them to us via our Report Abuse page . Also, if you want to help enforce the Code of Conduct, you might consider becoming a DEV moderator. Visit the DEV Community Moderation page for more information on roles and how to get involved.

Glossary / argument In Python, an argument is a value or object that you pass into a function or method when you call it. Arguments allow you to provide input data to the function so that it can perform its task. Functions can accept any number of arguments, which can be of any type , including custom objects. Arguments can be classified into two main categories: Positional arguments must be passed in the same order as defined in the function’s signature. Keyword arguments are provided as argument_name=value , allowing you to specify which parameter they correspond to, regardless of their order. Arguments vs Parameters When defining a function, you specify parameters in its signature. They act as placeholders for the arguments . When you call the function, you provide the arguments that correspond to these parameters. Example Here’s an example of a function that takes two arguments, and it’s called with both positional and keyword arguments: Python >>> def greet ( name , greeting ): ... print ( f " { greeting } , { name } !" ) ... >>> greet ( "Alice" , "Hello" ) # Called with positional arguments Hello, Alice! >>> greet ( name = "Bob" , greeting = "Hi" ) # Called with keyword arguments Hi, Bob! In this example, you first call greet() with positional arguments "Alice" and "Hello" . In the second call, you use keyword arguments name="Bob" and greeting="Hi" .

(" 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.

Report Abuse Ava Mendes Posted on Dec 19, 2025 Smart Meters em Condomínios: Impactos Legais e Técnicos na Portabilidade até 2027 # energy # smarthomes # iot # smartcities Smart Meters em Condomínios: Impactos Legais e Técnicos na Portabilidade até 2027 Você mora em um condomínio e recebe uma conta de luz cada vez mais cara? A boa notícia é que uma revolução silenciosa está acontecendo nas redes elétricas brasileiras — e pode afetar significativamente quanto você paga pela energia. Os medidores inteligentes (smart meters) estão chegando aos condomínios brasileiros em ritmo acelerado. Mas o que isso significa na prática? Como afeta a portabilidade da conta de luz? E, mais importante: quanto você pode economizar? Neste artigo, você vai descobrir como essa tecnologia funciona, que impactos legais e técnicos ela traz para condomínios, e como se preparar para as mudanças que virão até 2027. O que são Smart Meters e por que estão chegando agora? Um medidor inteligente não é apenas um aparelhinho que mede seu consumo. É um dispositivo conectado que se comunica constantemente com a distribuidora de energia, enviando dados de consumo em intervalos muito curtos — geralmente a cada 15 minutos. Diferente dos medidores convencionais, que exigem leitura manual mensal, os smart meters funcionam assim: Leitura remota automática : A distribuidora não precisa enviar um leitor até sua casa Dados granulares : Você sabe exatamente quanto consumiu em cada período do dia Comunicação bidirecional : A distribuidora pode se comunicar com o medidor e até desligar remotamente em caso de inadimplência Detecção de anomalias : O sistema identifica rápido quando há vazamentos de energia ou fraudes Por que agora? O Brasil tem cerca de 90 milhões de consumidores de energia, e apenas 4 milhões possuem medidores inteligentes instalados (dados de 2024). O Ministério de Minas e Energia abriu em 2025 uma consulta pública estabelecendo metas: cada distribuidora deve instalar smart meters em pelo menos 4% de suas unidades consumidoras em 12 meses. Grandes distribuidoras já estão nessa corrida. A Copel, no Paraná, instalou 1,7 milhão de unidades. A Cemig substituiu mais de 2 milhões desde 2021. A CPFL investirá R$ 1,2 bilhão para trocar 1,6 milhão de medidores até 2029. Como Smart Meters Funcionam em Condomínios Em um condomínio, a situação é um pouco diferente de uma casa isolada. Existem dois cenários principais: Medição Coletiva Ainda é o modelo mais comum. Um único medidor registra todo o consumo do condomínio (áreas comuns + todas as unidades), e a conta é dividida entre os moradores — geralmente por rateio igual ou proporcional à metragem. Problema? Quem usa pouca energia subsidia quem usa muita. Não há incentivo individual para economizar. Medição Individualizada com Smart Meters Cada unidade tem seu próprio medidor inteligente. A distribuidora mede o consumo de forma independente, e cada morador paga apenas pelo que consome. Vantagem? Justiça tarifária total. Se você desligar a luz, a economia aparece na sua conta, não na do vizinho. A medição individualizada com smart meters é tecnicamente viável e está crescendo em condomínios novos e em reformas. Mas exige uma estrutura elétrica adequada e, claro, vontade do condomínio em modernizar. Impactos Legais: O que Muda até 2027? Aqui está a questão que mais interessa: medidores inteligentes são obrigatórios para portabilidade da conta até 2027? A resposta é: ainda não há regra específica que torne isso obrigatório , mas a tecnologia é considerada pré-requisito técnico para modelos avançados de escolha de fornecedor. A Portaria MME nº 111/2025 Em 2025, o Ministério de Minas e Energia publicou diretrizes para digitalização das redes de distribuição. Essa portaria estabelece 13 diretrizes, incluindo: Inovação em serviços (tarifas dinâmicas, resposta à demanda) Transparência de dados de consumo Resiliência a eventos climáticos extremos Avaliação de desempenho das distribuidoras O que isso significa? Smart meters são a base técnica para que o Brasil consiga oferecer serviços mais avançados e, eventualmente, abrir o mercado livre para residências e pequenos comércios. Abertura do Mercado Livre em 2026-2027 A CCEE (Câmara de Comercialização de Energia Elétrica) tem discutido a abertura do mercado livre para consumidores de baixa tensão. Quando isso acontecer, famílias e pequenos comércios poderão escolher seu fornecedor de energia — assim como já fazem as grandes empresas. Requisito técnico? Medição precisa e transparente. Os smart meters facilitam enormemente isso, pois permitem comparações reais de consumo entre fornecedores. Impactos Técnicos: Como Muda a Operação do Condomínio? Eliminação da Leitura Manual Hoje, um leitor da distribuidora passa mensalmente no condomínio para anotar o consumo. Com smart meters, isso desaparece. Mais prático? Sim. Menos burocracia? Com certeza. Acesso a Dados Detalhados via App Distribuidoras como Copel já oferecem aplicativos onde você acompanha seu consumo em intervalos de 15 minutos. Isso permite identificar: Qual eletrodoméstico consome mais Em que horários o consumo é maior Padrões de desperdício Possibilidade de Tarifas Horárias Com dados granulares, a distribuidora pode oferecer tarifas diferenciadas por horário — mais cara no pico (18h-21h), mais barata fora do pico. Para famílias de alto consumo em condomínios, isso abre oportunidade: deslocar cargas (máquina de lavar, aquecedor) para fora do pico pode gerar economia real. Integração com Automação Smart meters se comunicam com sistemas de automação residencial. Você pode programar que o ar-condicionado ligue apenas fora do horário de pico, por exemplo. Economia Real: Quanto Você Pode Poupar? Aqui está a verdade: o medidor inteligente, por si só, não reduz sua conta de luz . Ele apenas fornece informações. A economia vem de ações que você toma com base nesses dados . Cenário 1: Família de Alto Consumo (R$ 600/mês) Com dados detalhados, essa família identifica que o ar-condicionado consome 40% da energia. Ao usá-lo apenas fora do pico (22h-6h), reduz o consumo em 25%. Economia: R$ 150/mês = R$ 1.800/ano Cenário 2: Portabilidade para Fornecedor do Mercado Livre Quando a abertura acontecer, famílias podem migrar para fornecedores com preço mais competitivo — como a energialex.app , que oferece energia 100% renovável com economia de até 20% para consumidores do Grupo B (residências e pequenos comércios). Economia: 20% na tarifa = R$ 120/mês em uma conta de R$ 600 Combine os dois cenários e você chega a R$ 270/mês de economia . Privacidade e Proteção de Dados em Condomínios Uma preocupação legítima: dados granulares de consumo revelam padrões de vida . Se o medidor registra que você liga o ar-condicionado às 14h todo dia de semana, isso pode revelar que você trabalha em casa. Se o consumo sobe drasticamente em certos dias, pode indicar festas ou visitas. Como se proteger? Conformidade com LGPD : O condomínio deve ter política clara de acesso e retenção de dados Anonimização : Relatórios gerenciais não devem identificar unidades específicas Controle de acesso : Apenas síndico e administradora devem ver dados individuais Transparência : Informar moradores sobre coleta e uso de dados Distribuidoras e plataformas como energialex.app já operam com conformidade à LGPD, armazenando dados de forma segura e permitindo que você controle o acesso. Checklist: Como Preparar seu Condomínio para Smart Meters Se você é síndico ou mora em condomínio e quer se preparar para essa transição: ☑ Passo 1: Mapeie a Situação Atual Qual tipo de medição tem seu condomínio (coletiva ou individualizada)? Os medidores são convencionais ou já há alguns inteligentes? Quando foi a última revisão do quadro elétrico? ☑ Passo 2: Consulte a Distribuidora Seu condomínio está em algum programa de substituição? Qual é o prazo estimado? Haverá custo para o condomínio? ☑ Passo 3: Avalie Benefícios Potenciais Quanto seu condomínio poderia economizar com medição individualizada? Há interesse dos moradores em automação residencial? ☑ Passo 4: Prepare a Governança de Dados Defina quem acessa relatórios de consumo Crie política de privacidade conforme LGPD Comunique aos moradores ☑ Passo 5: Acompanhe Regulamentação Fique atento a mudanças na ANEEL e CCEE Quando a abertura do mercado livre chegar, seu condomínio estará pronto FAQ: Dúvidas Frequentes sobre Smart Meters em Condomínios P: Medidores inteligentes aumentam ou diminuem a conta? R: Não aumentam automaticamente. Diminuem apenas se você usar os dados para reduzir consumo ou migrar para fornecedor mais barato. P: Quem paga pela instalação? R: Na maioria dos casos, a distribuidora investe e recupera via tarifa. Não há custo direto para o condomínio ou morador. P: Posso recusar o smart meter? R: Não. É decisão da distribuidora, não do consumidor. Mas o processo é simples e sem obras. P: Quando meu condomínio terá smart meter? R: Depende da distribuidora e região. Metas atuais são 4% das unidades em 12 meses. Você pode consultar sua distribuidora. Conclusão: O Futuro já Começou Os smart meters não são ficção científica. Estão chegando aos condomínios brasileiros agora. Até 2027, a expectativa é que milhões de unidades tenham essa tecnologia, criando base para abertura do mercado livre e novos modelos de tarifação. Para você, morador de condomínio, isso significa: ✅ Mais transparência no consumo de energia ✅ Oportunidade de economizar através de gestão inteligente ✅ Possibilidade de escolher fornecedor quando o mercado abrir ✅ Maior segurança contra fraudes e perdas técnicas Quer ir além? Quando a portabilidade da conta for possível, plataformas como energialex.app tornam o processo simples, 100% online e gratuito. Você pode simular sua economia em menos de 2 minutos — sem compromisso, sem burocracia, sem custos. O futuro da energia é digital, inteligente e mais justo. E você pode começar a se preparar hoje.

Report Abuse Doug silkstone Posted on Feb 11, 2025 Spin up a License Key API on new Railway Functions In Less Than Two Minutes! # serverless # javascript # bunjs # railway Railway's new Functions feature makes it incredibly easy to deploy single-file TypeScript code without the overhead of managing infrastructure or repositories. In this article, we'll walk through building a license API using Hono , Redis, and the Bun runtime—all in a single file. No more excuses, it's time to build software! Note: Railway Functions are perfect for small tasks like handling webhooks, cron jobs, or simple APIs. What makes them even better is how they interact with the rest of the Railway ecosystem. Customizing Your Prefixes Before diving in, make sure to edit the prefix values in the code to suit your needs. The default prefixes, such as WTHSEISMIC_ , are placeholders and should be replaced with values relevant to your project to ensure uniqueness and avoid conflicts. Prerequisites A Railway account. Basic knowledge of TypeScript. Familiarity with serverless concepts. Step 1: Set Up a New Project Create a New Project: Head over to your Railway dashboard and create a new project. Choose the Functions service to get started. Select the Functions Environment: Railway will automatically set up the environment using the Bun runtime for your function. No need for additional configuration! Step 2: Provision Redis Add a Redis Service: In your Railway project, provision a Redis service. This will be used to store license data. Share Environment Variables: After provisioning Redis, click on the Redis service, then head to Variables . Use the "Share Variables" feature to expose the following environment variables to your function: REDISHOST REDISPORT REDISUSER REDISPASSWORD (Optional) REDIS_TLS if your Redis requires TLS. Step 3: Create Your Function Create a New Function: In the Railway dashboard, click New Function . This opens the built-in editor which supports TypeScript using Bun. Set Up Additional Environment Variables: Add any additional variables your API requires. For example, generate unique values (e.g., using a UUID generator) for: ADMIN_KEY HMAC_SECRET PAYMENT_SECRET Optionally, set PORT (defaults to 3000 if not provided). Step 4: Paste and Save the Code Copy and paste the following complete code into the Source Code tab of your Railway Function. Save your changes using ⌘+S (or Ctrl+S on Windows). Railway will automatically deploy your changes! // index.ts import { Hono } from " hono " ; import { cors } from " hono/cors " ; import { rateLimiter } from " hono-rate-limiter " ; import Redis from " ioredis " ; import crypto from " node:crypto " ; // Custom prefix configuration const LICENSE_PREFIX = " WTHSEISMIC_ " ; const LICENSE_SET = " WTHSEISMIC_LICENSES " ; const WEBHOOK_SET = " WTHSEISMIC_WEBHOOKS " ; // Updated LicenseTier type to include "unlimited" type LicenseTier = " basic " | " pro " | " enterprise " | " unlimited " ; ... ( full code here ) Enter fullscreen mode Exit fullscreen mode Step 5: Test Your Deployment Once deployed, Railway provides a URL for your function. Use the following curl commands to test each endpoint: 5.1: Test the Root Endpoint Returns the current timestamp. curl -X GET https://<your-function-url>/ Enter fullscreen mode Exit fullscreen mode 5.2: Create a New License Creates a new license key for a user. curl -X POST https://<your-function-url>/api/licenses \ -H "Content-Type: application/json" \ -d '{"email": "user@example.com", "tier": "pro", "durationDays": 90}' Enter fullscreen mode Exit fullscreen mode 5.3: Validate a License Validates an existing license key. curl -X GET https://<your-function-url>/api/licenses/WTHSEISMIC_xxx Enter fullscreen mode Exit fullscreen mode 5.4: Handle Payment Webhook Simulates a payment webhook to extend a license's duration. curl -X POST https://<your-function-url>/webhooks/payment \ -H "Content-Type: text/plain" \ -H "X-Payment-Signature: <signature>" \ -d '{"licenseKey": "WTHSEISMIC_xxx", "durationDays": 30}' Enter fullscreen mode Exit fullscreen mode 5.5: Extend License via Admin Endpoint Extends the license duration using an admin key. curl -X POST https://<your-function-url>/admin/licenses/WTHSEISMIC_xxx/extend \ -H "Content-Type: application/json" \ -H "X-Admin-Key: your-secret-key" \ -d '{"durationDays": 30}' Enter fullscreen mode Exit fullscreen mode Use these examples to verify that your function is working as expected. So there you have it, in less than two minutes, we've put together a license key server on Railway using Redis, Hono and Bun - Demonstrating how headache-free the whole process is, and how (not so) small snippets of code can live within your Railway ecoystem within minutes. Great feature, great platform. Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

Report Abuse wellallyTech Posted on Jan 9 • Originally published at wellally.tech Accessible Visuals: How Inclusive Charts Empower Patient Health # frontend # react # a11y # healthtech In the world of health technology, data visualizations are essential tools for clarity. They translate complex biometrics—like heart rate trends or sleep cycles—into manageable insights that empower us to take action. However, when these dashboards are not designed for accessibility, we inadvertently create barriers for users with disabilities. Ensuring your data is readable for everyone is the first step toward a more inclusive understanding of your results . The Hidden Barrier in Health Dashboards Many health tech platforms rely heavily on "visual-first" designs that can exclude those using screen readers or living with color vision deficiencies. A standard chart often appears as a "black box" to assistive technology if it lacks proper semantic markers. Research suggests that accessible design is not just a compliance requirement; it is associated with better health literacy. When data is structured correctly, every user can interpret their health trends regardless of how they interact with the screen. Moving Beyond Color-Only Data A common pitfall in health apps is using color as the only way to convey meaning—such as red for "high risk" or green for "optimal." For many, these distinctions are invisible. To solve this, developers are encouraged to use patterns and textures to differentiate data points. For example, a striped bar vs. a solid bar ensures that information remains clear even in grayscale or high-contrast modes. Navigating with Intention Interactive charts should be fully navigable via keyboard, not just a mouse. By implementing tabIndex and custom keyboard hooks, users can "tab" through their health metrics one by one. This level of control allows for a focused review of specific data points, such as a single day's step count. This structured approach is often suggested for reducing "information overload" during health tracking. Quick Checklist: Is Your Health Chart Accessible? Feature Requirement Purpose ARIA Roles role="img" or role="listitem" Narrates data to screen readers. Contrast Minimum 3:1 ratio Ensures visibility for low-vision users. Labels aria-label for every data point Provides context for specific values. Keyboard Full Arrow Key support Allows navigation without a mouse. Conclusion: Building for Every User Creating accessible health visualizations is a commitment to ethical design. By focusing on semantic code, keyboard navigation, and color independence, we ensure that health data remains a tool for empowerment rather than a source of frustration. 3 Key Takeaways: Semantics Matter : Use ARIA roles to describe the "story" the chart is telling. Go Beyond Color : Use shapes or patterns to define different health metrics. Ensure Keyboard Focus : Every interactive data point must be reachable via the "Tab" key.

Introduction Google open sourced TensorFlow in the hope of sharing technology with the external community and encouraging collaboration between researchers and industry. With over 190,000 GitHub stars, TensorFlow has become the world's most popular machine learning framework, powering everything from research projects to production AI systems at major tech companies. We researched TensorFlow on collab.dev and discovered a fascinating example of community-driven development taken to its logical extreme. TensorFlow's Hidden Review Process Understanding TensorFlow's collaboration metrics requires looking beyond what's visible in public GitHub data. While the project appears community-driven on the surface, the team maintains rigorous quality controls through their internal "copybara" system that external metrics tools can't capture. Every PR is assigned to a reviewer or maintainer, ensuring no contribution goes without proper oversight. Image taken from TensorFlow Contributor Guidelines Every TensorFlow PR follows this comprehensive workflow: Validation : Google inspects every PR for CLA signatures, sufficient descriptions, unit tests, and contribution quality Assignment : Valid PRs get assigned to internal reviewers familiar with the code Review Cycle : Contributors and reviewers iterate until approval Internal Testing : Approved PRs receive the "kokoro:force-run" label, triggering CI/CD tests Copybara Integration : Code gets copied to Google's internal codebase for additional integration testing Final Merge : Only after passing all internal tests does the code merge both internally and externally Image taken from TensorFlow Contributor Guidelines This behind-the-scenes process explains many of TensorFlow's seemingly contradictory metrics - what appears as minimal formal review actually represents one of the most thorough validation systems in open source. Key Highlights TensorFlow's collaboration metrics paint a picture of a unique hybrid model that combines community-driven development with enterprise-grade quality controls: Extreme Community Focus : With 97% community contributions and 0% core team involvement, TensorFlow represents the most community-driven development model among major tech company projects. Google has genuinely stepped back from day-to-day coding. Fast First Reviews, Thorough Process : All PRs receive their first review within 24 hours, by being assigned to a reviewer, but 75% take 4-5 days from creation to merge due to comprehensive internal validation. Minimal Automation : Only 2.8% bot activity keeps TensorFlow's development fundamentally human-driven, despite its massive scale. This contrasts with many projects that rely heavily on automation. The Quality Paradox : While appearing to have low review coverage (5%) publicly, TensorFlow actually maintains rigorous quality standards through internal processes invisible to external metrics tools. TensorFlow demonstrates that major tech companies can successfully transition to community-led development without sacrificing quality. The key is building robust internal validation systems that complement public collaboration. For contributors, this means fast initial feedback but longer approval cycles due to comprehensive internal testing. This model could serve as a blueprint for other large-scale open source projects seeking to balance community empowerment with enterprise reliability requirements. collab.dev/tensorflow/tensorflow collab.dev pullflow.com 🍩 Project of the Week (26 Part Series) 1 Introducing: Project of the Week! 2 Project of the Week: Prisma ... 22 more parts... 3 Project of the Week: TanStack Query 4 Project of the Week: HedgeDoc 🦔 5 Project of the Week: Grafana 6 Project of the Week: Ghost 👻 7 Project of the Week: TensorFlow 8 Project of the Week: MapLibre 9 Project of the Week: Windmill 10 Project of the Week: Deno 11 Project of the Week - 10 Weeks Later! 12 Project of the Week: Excalidraw 13 Project of the Week: Supabase 14 Project of the Week: Clerk 15 Project of the Week: freeCodeCamp 16 Project of the Week: Appwrite 17 Project of the Week: Chart.js 18 Project of the Week: n8n 19 Project of the Week: PyTorch 20 Project of the Week: Emotion-js 21 Project of the Week: Chainguard 22 Project of the Week: Dify 23 Project of the Week: Alpine.js 24 Project of the Week: Svelte 25 Project of the Week: .NET Runtime 26 LobeChat: Where Bots Write 23% of the Code and Reviews Take 42 Seconds Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

A Python Trick either teaches an aspect of Python with a simple illustration, or serves as a motivating example to dig deeper and develop an intuitive understanding. Here are a few examples of the kinds of tricks you’ll receive: Python # How to merge two dictionaries # in Python 3.5+: >>> x = { 'a' : 1 , 'b' : 2 } >>> y = { 'b' : 3 , 'c' : 4 } >>> z = { ** x , ** y } >>> z { 'c' : 4 , 'a' : 1 , 'b' : 3 } # In Python 2.x you could use this: >>> z = dict ( x , ** y ) >>> z { 'a' : 1 , 'c' : 4 , 'b' : 3 } Python # Why Python Is Great: # Function argument unpacking def myfunc ( x , y , z ): print ( x , y , z ) tuple_vec = ( 1 , 0 , 1 ) dict_vec = { 'x' : 1 , 'y' : 0 , 'z' : 1 } >>> myfunc ( * tuple_vec ) 1 , 0 , 1 >>> myfunc ( ** dict_vec ) 1 , 0 , 1 Python # The lambda keyword in Python provides a # shortcut for declaring small and # anonymous functions: >>> add = lambda x , y : x + y >>> add ( 5 , 3 ) 8 # You could declare the same add() # function with the def keyword: >>> def add ( x , y ): ... return x + y >>> add ( 5 , 3 ) 8 # So what's the big fuss about? # Lambdas are *function expressions*: >>> ( lambda x , y : x + y )( 5 , 3 ) 8 # → Lambda functions are single-expression # functions that are not necessarily bound # to a name (they can be anonymous). # → Lambda functions can't use regular # Python statements and always include an # implicit `return` statement.

Navigation PREFERENCE CENTRE Angular Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog PREFERENCE CENTRE Angular OpenAI Open in ChatGPT Integration guide to add notification preference centre in Angular website. OpenAI Open in ChatGPT **Preferences changes in @suprsend/web-sdk version >=2.0.0 In @suprsend/ [email protected] we have revamped SDK. The whole structure of preferences have been changed from SDK side. Please upgrade to newer versions. Old version of documentation for preference is available here . Pre-Requisites Integrate JavaScript SDK Identify user on login and reset on logout to ensure that preference changes are tagged to the correct user Configure notification categories on SuprSend dashboard Understanding of the preference data structure and methods Example implementation GitHub Repository for this example implementation can be found here: (“ https://github.com/suprsend/angular-example ”) Integration There will be 3 components in example implementation: preference channel-level-preferences category-level-preferences Preference component setup preference will be the main component and inside it, there will be a property (preferencesData) that contains full user preference data. Whenever there’s an update we will update the latest preference data in the preferencesData so that component to rerender. We already created SuprSend service to access SuprSend client everywhere in the application which is used to call methods. Call getPreferences method to get the preferences data for the already identified user. This method is used to get full user preferences data from the SuprSend. This method should be called first before any update methods. Calling this method will make an API call and returns a preference response, which you can store in your instance property preferenceData if there is no error. Note: Category translations work automatically—no additional configuration required. Since the Angular SDK is built on the web SDK, the locale is automatically passed through the underlying web SDK, and all embeddable SDKs in the preference centre inherit this behavior. Category names and descriptions are automatically displayed in the user’s locale. After that we configure 2 event listeners preferences_updated and preferences_error to listen to updates in preference data and errors. Our Main component preference has 2 child components one for Category-level preference section and other for Overall Channel-level preference section. preference.component.ts Copy Ask AI import { SuprsendService } from '../suprsend.service' ; @ Component ({ ... }) export class PreferenceComponent implements OnInit { preferencesData : any = null ; constructor ( private router : Router , private ssService : SuprsendService ) {} ngOnInit () : void { // before getting preferences make sure to call identify method // Translations work automatically - locale is passed by the web SDK automatically this . ssService . ssClient . user . preferences . getPreferences ({ locale: 'en' }). then (( resp ) => { if ( resp . status === 'error' ) { console . log ( resp . error ); } else { this . preferencesData = resp . body ; } }); // listen for update in preferences data this . ssService . ssClient . emitter . on ( 'preferences_updated' , ( preferenceData ) => { this . preferencesData = { ... preferenceData . body } } ); // listen for errors this . ssService . ssClient . emitter . on ( 'preferences_error' , ( error ) => { console . log ( 'ERROR:' , error ); }); } } preference.component.html Copy Ask AI < p * ngIf = "!this.preferencesData" > Loading ...</ p > < div * ngIf = "this.preferencesData" class = "main-div" > < h3 class = "main-header" > Notification Preferences </ h3 > <!-- notification category level preferences --> < app - category - level - preferences [ preferencesData ] = "this.preferencesData" > </ app - category - level - preferences > <!-- overall channel level preferences --> < app - channel - level - preferences [ preferencesData ] = "this.preferencesData" > </ app - channel - level - preferences > </ div > preference.component.css Copy Ask AI .main-div { margin : 24 px ; } .main-header { margin-bottom : 24 px ; } p , h3 { margin : 0 ; padding : 0 ; font-family : Arial , Helvetica , sans-serif ; } Category level Preference section In category-level preferences, you’ll have to fetch the data from 3 parts: Section -to show sections like “Product Updates” in below example Category -to show categories and their overall status like “Refunds” in below example CategoryChannel -to show communication channels inside the category and their status Below are the steps to render category preference UI: Loop through the property preferenceData.sections for showing sections, show sub-categories inside each section, and show subcategory’s channels inside each sub-category. Add a switch button next to each sub-category for opting in and out of the category. Add checkbox components in sub-category channels for opting in and out of category-channel. You can use any third-party npm package to import these components or design your own component. To update category preference on the click of the switch button, call updateCategoryPreference method and if no error is received in response, update the latest data in the instance property. For preference state opt-in set the switch state as on and off for the opt-out state. To update category-channel preference on the click of checkbox next to each channel, call the updateChannelPreferenceInCategory method. Update the latest data in the instance property if no error is received in response. For preference state opt-in set the checkbox state as checked and unchecked for the opt-out state. category-level-preferences.component.ts Copy Ask AI import { Component , Input } from '@angular/core' ; import { PreferenceOptions } from '@suprsend/web-sdk' ; import { SuprsendService } from '../suprsend.service' ; @ Component ({ selector: 'app-category-level-preferences' , templateUrl: './category-level-preferences.component.html' , styleUrls: [ './category-level-preferences.component.css' ], }) export class CategoryLevelPreferencesComponent { @ Input () public preferencesData : any ; constructor ( private ssService : SuprsendService ) {} async handleCategoryPreferenceChange ( e : boolean , subcategory : string ) { const resp = await this . ssService . ssClient . user . preferences . updateCategoryPreference ( subcategory , e ?

Report Abuse Hala Kabir Posted on Dec 20, 2025 I Built a Smart Accounting App Called AccountInn (And It Taught Me How Real Apps Are Built ) # webdev # ai # tutorial # learning Ever wondered how accounting apps actually work behind the scenes? No endless spreadsheets. No confusing formulas. Just logic, rules, and structured data making sure every number makes sense… or gets rejected 😅 That curiosity led me to build AccountInn — a beginner-friendly accounting and learning app designed to make finance simple, practical, and approachable. Let’s break it down: What Is AccountInn? AccountInn is an accounting and learning app created for Students Beginners in finance & tech_ Small businesses and individuals_ The goal is simple: make accounting understandable, organized, and stress-free. 📸 Screenshot What AccountInn Can Do AccountInn focuses on real, everyday needs:_ ✅ Secure login system ✅ Income & expense tracking ✅ Journal entries for financial records ✅ Courses for learning accounting concepts ✅ Chatbot support for quick help ✅ Leaderboard to encourage learning ✅ Digital library for resources All features are built with simplicity and clarity in mind. 📸 Screenshots ** AccountInn Thinks Like a Digital Accountant** AccountInn doesn’t guess.

(" 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 .

Report Abuse Nočnica Mellifera Posted on Sep 30, 2025 Filling Out Forms with Playwright: Choosing Between `fill()` and `pressSequentially()` # playwright Filling out forms is one of the most common tasks in web automation and testing. When using Playwright, you have two primary methods for entering text into input fields: .fill() and .pressSequentially() . While both accomplish the same basic goal, choosing the right method can significantly impact the stability, realism, and effectiveness of your tests. The Default Choice: locator.fill() For most scenarios, locator.fill() should be your go-to method. It's fast, efficient, and simulates what happens when a user pastes text into a field. When to use fill() : Simple text inputs without dynamic behavior When you need to quickly populate form fields For basic form submissions where typing simulation isn't critical // Simple and efficient for most cases await page . locator ( ' #username ' ). fill ( ' testuser ' ); await page . locator ( ' #email ' ). fill ( ' user@example.com ' ); Enter fullscreen mode Exit fullscreen mode When to Switch to pressSequentially() The community discussion reveals several specific scenarios where pressSequentially() becomes necessary: 1. Testing Auto-complete and Search Suggestions If you're searching for "Doug Bowser" and want to test the intermediate suggestions that appear as you type "D", "Do", "Dou", etc., fill() won't trigger these incremental updates. // Triggers search suggestions at each keystroke await page . locator ( ' #search ' ). pressSequentially ( ' Doug Bowser ' , { delay : 100 }); Enter fullscreen mode Exit fullscreen mode 2. Triggering Field Validations Some forms validate input as users type. If you need to test this real-time validation behavior, pressSequentially() allows you to simulate the actual typing process that triggers these validations. 3. Making Automation Less Detectable When scraping or performing long-running automation tasks, instantaneous text entry can be a telltale sign of bot activity. pressSequentially() with appropriate delays can help mimic human typing patterns. // More human-like typing behavior await page . locator ( ' #message ' ). pressSequentially ( ' Hello, this is a longer message ' , { delay : 50 // milliseconds between keystrokes }); Enter fullscreen mode Exit fullscreen mode You could even randomize these delay times for multiple form fills. 4. Testing Learning Applications For applications that grade typing velocity and accuracy, or any scenario where the timing and sequence of keystrokes matter, pressSequentially() is clearly the right choice. Practical Recommendations Based on the community consensus: Start with fill() - It's faster and sufficient for most cases Switch to pressSequentially() when you need: To trigger intermediate API calls or UI updates To test real-time validation More realistic user behavior simulation To avoid detection in scraping scenarios Use the delay option to control typing speed when realism matters: await page . locator ( ' #input ' ). pressSequentially ( ' text ' , { delay : 100 }); Enter fullscreen mode Exit fullscreen mode Conclusion While fill() will handle most of your form-filling needs efficiently, pressSequentially() is your tool for scenarios requiring realistic typing behavior. The key is understanding your application's behavior and choosing the method that best matches how real users interact with your forms. Whether you're testing search suggestions, form validations, or simply trying to make your automation more human-like, having both methods in your Playwright toolkit ensures you can handle any form-filling scenario effectively.

(" 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.

(" 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.

Report Abuse Beeptec Engineering Posted on Sep 15, 2025 BEEPTOOLKIT - IDE Soft Logic Controller # discuss # automation # softwaredevelopment # softwareengineering If your day-to-day thinking is in sequences, interlocks, timers, and states — not in parsing exceptions or juggling callbacks — this is for you. Think “executable behavior” first, then map it to sensors, actuators, and I/O without getting dragged into boilerplate. Who this speaks to Engineers who design behavior as finite steps and transitions: start > check > act > confirm \ fail-safe. Folks who care about what happens, when it happens, and why — with a clear way to prove it on the rig, not just in a doc. What “visual-first” means in practice State/transition logic is explicit: you see active states, guarded transitions, timers, and interlocks on one canvas. Signals are first-class: digital/analog/events flow through typed interfaces you can probe and replay. Orchestration before code: behavior runs as a model; custom code plugs in only where algorithms are truly needed. Video demo BEEPTOOLKIT — IDE + Soft Logic Controller concept (x86, Windows 10 LTSC/IoT, affordable USB I/O, no soldering for core orchestration) Where this shines Test stands and bring-up: trace transitions, log signals, reproduce incidents. No mystery states. Lab automation and robotics sequences: deterministic timers, guarded actions, safe defaults by design. Education and handoff: the diagram is the spec — easy to review with mechanical, electrical, and QA peers. Where code still wins Heavy algorithms (vision, optimization), custom protocols, and tight low-level loops. Drop in a module, don’t fight the model. A word on “classic scripting” devs By “classic coders on scripting languages” here, we mean folks who express control mainly with if/switch trees, nested loops, async calls, and exceptions — fast to write, flexible, but not always aligned with how physical processes are orchestrated. The goal isn’t to replace that skillset; it’s to move orchestration into a model and use code where it truly pays off. Discussion prompts What’s your safety baseline? Interlocks, watchdogs, and fail-safe states you consider non-negotiable. How do you partition behavior vs. algorithm? Clear rule-of-thumb examples welcome. USB I/O scaling tips: hubs, power budgets, device enumeration strategies that survived production. No hype, just practice Treat behavior as the top-level artifact. Make it observable. Keep the “why” attached to the “what” and “when.” Use code surgically. Avoid turning control flow into a thicket if the process is naturally a state machine. Thanks for reading. Share your field stories — the sequences that saved time, the interlocks that prevented damage, and the logs that told the truth when things went sideways.
