Guido remains Python’s principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see https://www.cnri.reston.va.us ) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/ ) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see https://opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived from Year Owner GPL-compatible? (1) 0.9.0 thru 1.2 n/a 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Note GPL-compatible doesn’t mean that we’re distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don’t. According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman’s lawyer has told CNRI’s lawyer that 1.6.1 is “not incompatible” with the GPL. Thanks to the many outside volunteers who have worked under Guido’s direction to make these releases possible.

A number of alternative implementations are available as well, namely PyPy (a fast implementation of Python with a JIT compiler) IronPython (Python running on .NET) MicroPython (Python running on microcontrollers and in the web browser ) Stackless Python (a branch of CPython supporting microthreads) Jython (Python running on the Java Virtual Machine) GraalPy (embeddable Python runtime for Java) Other parties have repackaged CPython. These re-packagings often include more libraries or are specialized for a particular application: Anaconda Python (a full Python distribution for data management, analysis and visualization of large data sets) ActiveState ActivePython (commercial and community versions, including scientific computing modules) Nuitka (a compiler that packages user code with CPython into a static binary for improved performance and IP protection) pyodide (a Python distribution for the browser and Node.js based on WebAssembly) WinPython (a portable scientific Python distribution for Windows) Python(x, y) (Scientific-oriented distribution based on Qt and Spyder) Conceptive Python SDK (targets business, desktop and database applications) PyIMSL Studio (a commercial distribution for numerical analysis – free for non-commercial use) eGenix PyRun (a portable Python runtime, complete with stdlib, frozen into a single 3.5MB - 13MB executable file) If you want to host and run Python in the cloud, these implementations may be right for you: PythonAnywhere (freemium hosted Python installation which lets you run Python in the browser, e.g. for tutorials, showcases) The PSF The Python Software Foundation is the organization behind Python.

http://legacy.python.org/doc/essays/ppt/ | Python Presentations Python Presentations In this directory I place slides of presentations I have given. Most presentations are available in HTML and PowerPoint (view the HTML index page and the follow the link labeled "Download presentation source"). [For the newer presentations I've given up making HTML. The HTML that PowerPoint generates gets worse with each version it seems. Thanks to Steve Holden for providing PDF.] -- Guido van Rossum Table of contents (in chronological order) Yahoo - March 1999 A generic introductory talk I gave on a visit to Yahoo, Inc. WWW8: Python - May 1999. A short talk about Python for developers' day at the Toronto WWW8 conference. WWW8: open source - May 1999. Another short talk, about running an Open Source project, for developers' day at the Toronto WWW8 conference. JPF001 - May 1999. A longer introductory talk I gave at the First French Python Day in Paris. HP training - July 1999. An intensive course for a group of more experienced Python developers at the Hewlett-Packard e-speak group, designed to give their coding skills and style a boost. Thanks to HP for allowing me to place this on the web. The State of Python - 23 August 1999. Opening address of the Python track at the O'Reilly Open Source Software Conference in Monterey. IDLE - 24 August 1999. IDLE - An Integrated DeveLopment Environment in and for Python - presented at the O'Reilly Open Source Software Conference in Monterey. CP4E - 9 October 1999. A presentation on Computer Programming for Everybody (CP4E) that I gave at the student conference of the ACM student chapter at the University of Illinois . Python Workshop - 10 October 1999. A Python tutorial that I gave at the student conference of the ACM student chapter at the University of Illinois . Using Python for CGI Programming - 12 November 1999. A brief generic Python tutorial followed by a tutorial on CGI programming using Python and a case study. These are the slides that I used at Software Development '99 East in Washington, DC. I never got to present the case study part, and the tail of both prior tutorials had to be cut off due to time constraints (ain't I bad :-). So here is all the material I had presented. Note that these are entirely different slides than the ones on the SD'99 website -- that was a longer tutorial plus some advanced Python material without any of the CGI material. OSCON 2001 Keynote The slides I used for my keynote-in-absentia at the Open Source Convention 2001, in San Diego, CA. ( PDF version ) Introduction to Python A 3 hour introductory tutorial that I gave at LinuxWorld in New York City, January 2002. It covers Python 2.2 (but mostly sticks to timeless features). ( PDF version ) What's New in Python 2.2 What the title says; a talk that I gave at LinuxWorld in New York City, January 2002, and earlier at a Washington, DC ZPUG meeting. ( PDF version ) Python 10 DevDay Keynote The slides I used for my Developers Day keynote at the Python10 Conference , February 2002 in Alexandria, VA ( PDF version ). See also the Parade of the PEPs . EuroPython 2002 Keynote The PowerPoint slides for my keynote at EuroPython 2002 . Similar to the next item. (Also available in pdf .) OSCON 2002 Keynote The PowerPoint slides for my keynote in the Python/Zope track at the O'Reilly Open Soure Convention 2002 . Derived from the previous item. (Also available in pdf .) Python Regrets A lightning talk I gave at OSCON 2002 about some minor flaws in Python. (Also available in pdf .) PyCon DC 2003 keynote The keynote I gave at the Python Conference in Washington, DC (March 26-28, 2003). Mostly about the Zen of Python. Python UK 2003 keynote The keynote I gave at the Python UK conference in Oxford, England (April 2-5, 2003). The audience was shared with the ACCU C/C++ conference. The title was "Why Design Another Language?" The subject matter was a historic overview of Python, with a a bit about the future thrown in for good measure. Python Updated version of a generic overview talk I've given many times; this time I presented it at a local Fannie Mae branch in Herndon on March 21, 2003. What's new in Python? (Not your usual list of new features) A new three-part talk that I first gave at the Stanford CSL colloquium , which also has the whole talk on video . After some promotional fluff, a dive into a lengthy discussion of iterators and generators, followed by a somewhat shorter discussion of descriptors. (Also available in pdf .) EuroPython 2004 Keynote The keynote presentation I gave on June 7 in Gothenburg, Sweden. Also available in pdf . OSCON 2004 Keynote The keynote presentation I gave on July 29 at OSCON in Portland Oregon. pdf .--> Building an Open Source Project and Community The slides I used for a presentation I gave at the SDForum distinguished speakers series on February 17, 2005 in Palo Alto, CA. The audio from this presentation is available at ITConversations . (The audio is much more interesting than the slides -- much of what I said was prompted by audience questions. :-) PyCon 2005 Keynote The keynote presentation I gave on March 24 at PyCon in Washington, DC. EuroPython 2005 Keynote The keynote presentation I gave on June 27 at EuroPython in Gothenburg, Sweden. Why I Invented Python A talk on the history of Python that I gave on June 27 at EuroPython in Gothenburg, Sweden. Python at Elemental Security A talk on the use of Python at Elemental Security (my employer) that I gave on June 29 at EuroPython in Gothenburg, Sweden. OSCON 2005 Keynote The keynote presentation I gave on August 3 at OSCON in Portland Oregon. pdf .--> ACCU 2006 - Python 3000 These are the slides on Python 3000 that I presented at the ACCU 2006 conference in Oxford on April 19. PyCon 2007 - Python 3000 These are the slides on Python 3000 that I presented at PyCon 2007 in Dallas, TX on February 24. PyCon 2008 - Python 3000 and You These are the slides on Python 3000 that I presented at PyCon 2008 in Chicago on March 14. ( PDF ) EuroPython 2008 - Python 3000 and You These are the slides on Python 3000 that I presented at EuroPython 2008 in Vilnius on July 7, via videoconferencing. Not too different from the PyCon 08 slides. ( PDF ) | 2026-01-13T08:49:04 |

Report Abuse Dinesh Dawonauth Posted on Dec 22, 2025 Looking for security feedback on a side project I’ve been building # beginners # tools # cryptography I’ve been working on a small side project in my spare time and I’d love some honest security focused feedback from this community The project is PassFX - a terminal based password manager designed to work entirely offline. No cloud sync, no accounts, no browser extensions. Everything is encrypted locally and unlocked with a single master passphrase that never leaves the machine. The core idea is simple: reduce attack surface by removing the cloud entirely. I wanted something: I could use on an air-gapped or offline machine That didn’t rely on a browser extension or remote service Where I could reason clearly about the threat model This isn’t meant to replace enterprise solutions or compete with hosted managers. It’s more of an exploration into how minimal and auditable a password manager can be while still being usable day to day for developers. What I’m looking for feedback on I’m especially interested in thoughts around: Cryptographic choices and key derivation approach Threat model assumptions (what I’m missing or underestimating) Secure storage practices on disk UX tradeoffs in terminal-only security tools Any obvious “don’t do this” red flags If you’re curious, the repo is here: GitHub: https://github.com/dinesh-git17/passfx Top comments (6) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

That's something I tackled very early on in the project. PassFX doesn't store individual entries or filenames as separate files. Everything lives in a single encrypted container on your disk. Entry names, metadata, and values are all encrypted together before being written. The only plaintext artifacts are the container file itself. The Salt and Vault are separated in different directories and if an attacker were to access those files, they'll see cypher text. Unless they have a supercomputer and a years to spend on this, they won't be able to decipher your encrypted passwords Like comment: Like comment: 1 like Like Comment button Reply Some comments may only be visible to logged-in visitors.

Report Abuse Arunava Modak Posted on Nov 14, 2021 React Router V5 vs V6 # webdev # javascript # react # reactrouter React Router version 6 was released recently, and it is important for us to understand the changes as it is one of the most widely used react libraries out there. So What Is React Router ? React Router is a fully-featured client and server-side routing library for React, a JavaScript library for building user interfaces. React Router runs anywhere React runs; on the web, on the server with node.js, and on React Native. In V6, there has been a lot of under the hood changes, be it an enhanced path pattern matching algorithm or addition of new components. Not only that but the bundle size has been reduced by almost 58%. So here are some of the changes you can make to upgrade an existing project from React Router v5 to v6. Switch Replaced With Routes In v6, Switch in not exported from react-router-dom . In the earlier version we could use Switch to wrap our routes. Now we use Routes to do the same thing instead of Switch . Changes In The Way We Define Our Route The component that should be rendered on matching a route can not be written as children of the Route component, but it takes a prop called element where we have to pass a JSX component for that to be rendered. The exact Prop Is Not Needed Anymore With version 6, React Router has just become alot more awesome. The now better, path matching algorithm, enables us to match a particular route match without the exact prop. Earlier, without exact , any URL starting with the concerned keyword would be loaded, as the matching process was done from top to down the route definitions. But now, we do not have to worry about that, as React Router has a better algorithm for loading the best route for a particular URL, the order of defining does not really matters now. So, to sum up these three points we can consider this code snippet. In v5 import { Switch , Route } from " react-router-dom " ; . . . < Switch > < Route path = " / " > < Home /> < /Route > < Route exact path = " /cryptocurrencies " > < Cryptocurrencies /> < /Route > < Route exact path = " /crypto/:coinId " > < CryptoDetails /> < /Route > < Route exact path = " /exchanges " > < Exchanges /> < /Route > < /Switch > Enter fullscreen mode Exit fullscreen mode In v6 import { Routes , Route } from " react-router-dom " ; . . . < Routes > < Route path = " / " element = { < Home /> } / > < Route path = " /crypto/:coinId " element = { < CryptoDetails /> } / > < Route path = " /cryptocurrencies " element = { < Cryptocurrencies /> } / > < Route path = " /exchanges " element = { < Exchanges /> } / > < /Routes > Enter fullscreen mode Exit fullscreen mode No Need To Install react-router-config Seperately react-router-config allowed us to define our routes as javascript objects, instead of React elements, and all it's functionalities have to moved in the core react router v6. //V5 import { renderRoutes } from " react-router-config " ; const routes = [ { path : " / " , exact : true , component : Home }, { path : " /cryptocurrencies " , exact : true , component : Cryptocurrencies }, { path : " /exchanges " , exact : true , component : Exchanges } ]; export default function App () { return ( < div > < Router > { renderRoutes ( routes )} < /Router > < /div > ); } //V6 function App () { let element = useRoutes ([ // These are the same as the props you provide to <Route> { path : " / " , element : < Home /> }, { path : " /cryptocurrencies " , element : < Cryptocurrencies /> , // Nested routes use a children property children : [ { path : " :coinId " , element : < CryptoDetails /> }, ] }, { path : " /exchanges " , element : < Exchanges /> }, ]); // The returned element will render the entire element // hierarchy with all the appropriate context it needs return element ; } Enter fullscreen mode Exit fullscreen mode useHistory Is Now useNavigate React Router v6 now has the navigate api, which most of the times would mean replacing useHistory to useNavigate . //V5 import { useHistory } from " react-router-dom " ; function News () { let history = useHistory (); function handleClick () { history . push ( " /home " ); } return ( < div > < button onClick = {() => { history . push ( " /home " ); }} > Home < /button > < /div > ); } //V6 import { useNavigate } from " react-router-dom " ; function News () { let navigate = useNavigate (); return ( < div > < button onClick = {() => { navigate ( " /home " ); }} > go home < /button > < /div > ); } Enter fullscreen mode Exit fullscreen mode Some more common features of useHistory were go , goBack and goForward . These can also be achieved by navigate api too, we just need to mention the number of steps we want to move forward or backward ('+' for forward and '-' for backward). So we can code these features we can consider this. //V5 import { useHistory } from " react-router-dom " ; function Exchanges () { const { go , goBack , goForward } = useHistory (); return ( <> < button onClick = {() => go ( - 2 )} > 2 steps back < /button > < button onClick = { goBack } > 1 step back < /button > < button onClick = { goForward } > 1 step forward < /button > < button onClick = {() => go ( 2 )} > 2 steps forward < /button > < / > ); } //V6 import { useNavigate } from " react-router-dom " ; function Exchanges () { const navigate = useNavigate (); return ( <> < button onClick = {() => navigate ( - 2 )} > 2 steps back < /button > < button onClick = {() => navigate ( - 1 )} > 1 step back < /button > < button onClick = {() => navigate ( 1 )} > 1 step forward < /button > < button onClick = {() => navigate ( 2 )} > 2 steps forward < /button > < / > ); } Enter fullscreen mode Exit fullscreen mode activeStyle and activeClassName Props Removed From <NavLink /> In the previous version we could set a seperate class or a style object for the time when the <NavLink/> would be active. In V6, these two props are removed, instead in case of Nav Links className and style props, work a bit differently. They take a function which in turn gives up some information about the link, for us to better control the styles. //V5 < NavLink to = " /news " style = {{ color : ' black ' }} activeStyle = {{ color : ' blue ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = " nav-link " activeClassName = " active " > Exchanges < /NavLink > //V6 < NavLink to = " /news " style = {({ isActive }) => { color : isActive ? ' blue ' : ' black ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = {({ isActive }) => " nav-link " + ( isActive ? " active " : "" )} > Exchanges < /NavLink > Enter fullscreen mode Exit fullscreen mode Replace Redirect with Navigate Redirect is no longer exported from react-router-dom , instead we use can Navigate to achieve the same features. //V5 import { Redirect } from " react-router-dom " ; < Route exact path = " /latest-news " > < Redirect to = " /news " > < /Route > < Route exact path = " /news " > < News /> < /Route > //V6 import { Navigate } from " react-router-dom " ; < Route path = " /latest-news " element = { < Navigate replace to = " /news " > } / > < Route path = " /news " element = { < Home /> } / > Enter fullscreen mode Exit fullscreen mode Please note the replace prop passed inside the element of the Route . This signifies we are replacing the current navigation stack. Without replace it would mean we are just pushing the component in the existing navigation stack. That's it for today. Hope this helps you upgrading your react project, to React Router V6. Thank you for reading !! 😇😇 Happy Coding !! Happy Building !!

If you want an SPA, you can use React and React Router, which takes care of your client-side routing. For something like Next.js it comes with it's own page based routing, I don't think we can implement SPA.

If you want the tools that Next or Gatsby offer then it makes sense to just go for those. If you're working on a more vanilla React project then you will generally see something like React Router in place to handle the routing.

For instance, with Next when you add a new JS/TS or JSX/TSX file into the pages folder, it will automatically map out the path for you without you having to define it.

With the Neon API, you manage all objects in your Neon account. 📘 Databases and roles belong to branches and are therefore managed with Branch endpoints. Look under Branch in the sidebar for database and role endpoints. For information about Neon objects, refer to Overview of the Neon object hierarchy , in the Neon documentation . Neon API base URL The base URL for a Neon API request is: https://console.neon.tech/api/v2/ Append a Neon API endpoint path to the base URL to construct the full URL for a request. For example: https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id} Neon OpenAPI Specification You can find the Neon OpenAPI specification here in JSON format: Neon OpenAPI specification Neon API examples For Neon API examples, refer to the following topics in the Neon documentation : Manage API keys with the Neon API Manage projects with the Neon API Manage branches with the Neon API Manage compute endpoints with the Neon API Manage roles with the Neon API Manage databases with the Neon API View operations with the Neon API Manage Organizations using the Neon API Query consumption metrics 📘 When using the Neon API programmatically, you can poll the operation status to ensure that an operation is finished before proceeding with the next API request.

https://sethmlarson.dev/ | Seth Larson Blog : About : RSS : Blogroll “Food JPEGs” in Super Smash Bros & Kirby Air Riders Have you ever noticed that the food graphics in Super Smash Bros. and Kirby Air Riders are flat “ billboarded ” stock images of food? This artistic decision from director Masahiro Sakurai has persisted through 8 games over nearly 25 years. I've seen a few folks online remarking about the “JPEG” or “PNG”-like quality of the images in the most recent release: Kirby Air Riders . While researching every game with this art style and all 150+ unique food images I ended up fixing wikis, reviewing a seasonal KitKat flavor, and preserving an uncatalogued image of tempura soba. New ROM dumping tool for SNES & Super Famicom from Epilogue Just heard the news from the WULFF Den Podcast that Epilogue has released pre-orders for the next ROM backup tool in their “Operator” series for the Super NES (SNES) and Super Famicom called the “ SN Operator ”. The SN Operator pre-order costs $60 USD plus shipping. This is great news for collectors and people interested in owning and playing SNES and Super Famicom games without a subscription service and for cheaper than purchasing a console , currently hovering around $120 USD on eBay. If there's only one or two games you're interested in playing and ownership isn't a huge deal for you: Nintendo Switch Online offers a substantial SNES and Super Famicom library for $20/year. Cutting spritesheets like cookies with Python & Pillow 🍪 Happy new year! 🎉 For an upcoming project on the blog requiring many video-game sprites I've created a small tool (“sugarcookie”) using the always-lovely Python image-processing library Pillow . This tool takes a spritesheet and a list of mask colors, a minimum size, and then cuts the spritesheet into its component sprites. I'm sure this could be implemented more efficiently, or with a friendly command line interface, but for more own purposes (~10 spritesheets) this worked just fine. Feel free to use, share, and improve. The script is available as a GitHub gist , but also included below. Nintendo GameCube and Switch “Wrapped” 2025 🎮🎁 One of my goals for 2025 was to play more games! I've been collecting play activity for my Nintendo Switch, Switch 2 , and my Nintendo GameCube . I've published a combined SQLite database with this data for 2025 with games, play sessions, and more. Feel free to dig into this data yourself, I've included some queries and my own thoughts, too. Getting started with Playdate on Ubuntu 🟨 Trina got me a Playdate for Christmas this year! I've always been intrigued by this console, as it is highly constrained in terms of pixel and color-depth (400x240, 2 colors), but also provides many helpful resources for game development such as a software development kit (SDK) and a simulator to quickly test games during development. I first discovered software programming as an amateur game developer using BYOND , so “returning to my roots” and doing some game development feels like a fun and fulfilling diversion from the current direction software is taking. Plus, I now have a reason to learn a new programming language: Lua! Blind Carbon Copy (BCC) for SMS Have you ever wanted the power of email Blind Carbon Copy (BCC), but for SMS? I've wanted this functionality myself for parties and organizing, specifically without needing to use a third-party service. This script automates the difficult parts of drafting and sending a text message to many recipients with SMS URLs and QR codes. Draft your message, choose your recipients, and then scan-and-send all the QR codes until you're done. Save your command for later to follow-up in different groups. PEP 770 Software Bill-of-Materials (SBOM) data from PyPI, Fedora, and Red Hat This year I authored PEP 770 which proposed a new standardized location for Software Bill-of-Materials (SBOM) data within Python wheel archives. SBOM data can now be stored in .dist-info/sboms/ . You can see the canonical specification on packaging.python.org . Delta emulator adds support for SEGA Genesis games The Delta emulator which I've used for mobile retro-gaming in the past has added beta support for SEGA Genesis and Master System games! Riley and Shane made the announcement through the Delta emulator Patreon and also on Mastodon . You can install the emulator on iOS through the “TestFlight” application to get access right away. I've done so and tested many of my favorite games including the Sonic the Hedgehog and the Streets of Rage trilogies and found that the emulator handled these games flawlessly. Extracting Nintendo Switch “Play Activity” with OCR Despite considering myself a “gamer”, I realized I had only played ~5 hours of video-games in the whole year 2022 and ~6 hours in 2021. Honestly, these numbers made me a bit sad to see... You can't “improve” what you don't measure, so I started looking for low-effort ways to measure the amount of play time while getting back into actually playing video-games . Deprecations via warnings don’t work for Python libraries Last week urllib3 v2.6.0 was released which contained removals for several APIs that we've known were problematic since 2019 and have been deprecated since 2022 . The deprecations were marked in the documentation, changelog, and what I incorrectly believed would be the most meaningful signal to users: with a DeprecationWarning being emitted for each use for the API. One weird trick for cheaper physical Switch 2 games? Maybe sell your boxes? I happened to be browsing PriceCharting and saw that only the box for Kirby Air Riders was selling for $20 on average. I couldn't believe my eyes! But I looked and there were at least two boxes sold on eBay. WebKit browsers see telephone numbers everywhere Just like Excel seeing everything as a date, WebKit mobile browsers automatically interpret many numbers as telephone numbers. When detected, mobile browsers replace the text in the HTML with a clickable <a href="tel:..."> value that when selected will call the number denoted. This can be helpful sometimes, but frustrating other times as random numbers in your HTML suddenly become useless hyperlinks. BrotliCFFI has two new maintainers Quick post announcing that the Python package brotlicffi has two new maintainers: Nathan Goldbaum and Christian Clauss . Thank you both for stepping up to help me with this package. Blogrolls are the Best(rolls) Happy 6-year blogiversary to me! 🎉 To celebrate I want to talk about other peoples’ blogs , more specifically the magic of “ blogrolls ”. Blogrolls are “lists of other sites that you read, are a follower of, or recommend”. Any blog can host a blogroll, or sometimes websites can be one big blogroll . Ice Pikmin and difficulty of Pikmin Bloom event decor sets I play Pikmin Bloom regularly with a group of friends. The game can be best described as “Pokémon Go, but walking”. One of the main goals of the game is to collect “ decor Pikmin ” which can come from the environment, landmarks, and businesses that you walk by. Recently there's been a change to the game that makes completing sets of decor Pikmin significantly more difficult , this post explores the new difficulty increase. GameCube Nintendo Classics and storage size If you're into GameCube collecting and archiving you may already know that GameCube ISOs or "ROMs" are around ~1.3 GB in size, regardless of the game that is contained within the .iso file. This is because GameCube ROMs are all copies of the same disk format: the GameCube Game disc (DOL-6). The GameCube Game disc is a 8cm miniDVD-based disc with a static storage capacity of 1.5 GB. Compare this to cartridges which using memory-mapping controllers (MMC) can encase different amounts of storage ROM depending on the size of the game data itself. RSS feed for new Nintendo Classics games It's November! Many folks use this month to write more, whether it's a novel or generating text . I'm going to be trying to write and share more often, too. So here's something I created for mostly me, but maybe you too. I've created a small RSS feed for new games being added to the Nintendo Classics collection over time. Nintendo uses this collection as the drippiest-of-drip-feeds, so there's typically only a few new games per month. So instead of checking frequently I can follow this feed in my feed reader and be notified on new releases. Easily create co-authored commits with GitHub handles You can add co-authors to a GitHub commit using the Co-authored-by field in the git commit message. But what if your co-author doesn't have a public email address listed on GitHub? No problem, you can use this handy script to automatically discover a users' display name and per-account "noreply" email address that'll mark their account as a co-author without a public email address. Drawing an ASCII TIE fighter for post-quantum cryptography This is a funny short story about contributing to internet standards. The real heroes of the story are Filippo Valsorda and all the other contributors to post-quantum cryptography standards (PQC). Without their efforts internet communications would be less secure, so thank you :) Re(blog, tweet, toot, skoot, skeеt, post) Have you noticed the similar terms used for sharing someone else's content with attribution from your own account? Reblogging was the original term for “blogging” another user's content, first developed by project “ reBlog ” and popularized by Tumblr . Remember that “blog” is a truncation of “weblog” (... should it have been ’blog to capture the shortening?) Is the "Nintendo Classics" collection a good value? Nintendo Classics is a collection of hundreds of retro video games from Nintendo (and Sega) consoles from the NES to the GameCube. Nintendo Classics is included with the Nintendo Switch Online (NSO) subscription, which starts at $20/year (~$1.66/month) for individual users. Looking at the prices of retro games these days, this seems like an incredible value for players that want to play these games. This post is sharing a dataset that I've curated about Nintendo Classics games and mapping their value to actual physical prices of the same games, with some interesting queries. Winning a bet about “six”, the Python 2 compatibility shim Exactly five years ago today Andrey Petrov and I made a bet about whether “ six ”, the compatibility shim for Python 2 and 3 APIs, would still be in the top 20 daily downloads on PyPI. I said it would, Andrey took the side against. Well, today I can say that I've won the bet. When the bet was placed, six was #2 in terms of daily downloads and today six is #14 . GZipped files and streams may contain names It's just another day, you're sending a bunch of files to a friend. For no particular reason you decide to name the archive with your controversial movie opinions: $ tar -cf i-did-not-care-for-the-godfather.tar *.txt $ gzip i-did-not-care-for-the-godfather.tar SCREAM CIPHER (“ǠĂȦẶAẦ ĂǍÄẴẶȦ”) You've probably heard of stream ciphers , but what about a scream cipher 😱? Today I learned there are more “ Latin capital letter A ” Unicode characters than there are letters in the English alphabet. You know what that means, it's time to scream: Infinite Precision CVSS Calculator CVSS is a scoring system for the severity of a software vulnerability. The scores range from 0 to 10, but that doesn't mean it's a “10-point system”. A single value after a decimal (“8.7”) is allowed too, meaning there are 100 potential CVSS scores. But what if we need more precision? Extracting NES & N64 ROMs from Zelda Collector's Edition Gaming as a hobby is about to become much more expensive in the United States due to tariffs. I cannot recall a time in the past where a console's price has increased during its generation , and yet the Xbox Series X & S , the Nintendo Switch , and most recently the Playstation 5 have had price hikes. These are not normal times. So here's another entry in my mini-series ( #1 , #2 ) of extracting ROMs from GameCube games, this time the “Zelda Collector's Edition” which contains 2 NES and 2 N64 Zelda titles. Draft SMS and iMessage from any computer keyboard If you're like me, you don't love the ergonomics of writing long text messages on your mobile phone keyboard. We own an “Arteck HB066” Bluetooth keyboard for this use-case which works great and costs $45. But I'm not interested in spending money today. What if I could write text messages, both SMS or iMessage, using any computer keyboard? The vulnerability might be in the proof-of-concept I'm on the security team for multiple open source projects with ~medium levels of report volume. Over the years, you see patterns in how reporters try to have a report accepted as a vulnerability in the project. One pattern that I see frequently is submitting proof-of-concept code that itself contains the vulnerability. However, the project code is also used, so the reporters try to convince you that the vulnerability is in the project code . SMS URLs Did you know there is a URL scheme for sending an “SMS” or text message, similar to mailto: ? SMS URLs are defined in RFC 5724 and are formatted like so: sms:<recipient(s)>?body=<body> Extracting Genesis & Game Gear ROMs from SEGA GameCube collections The GameCube library had multiple SEGA game collections: Sonic Mega Collection, Sonic Adventure DX, and Sonic Gems Collection which all contain ROM files for the Genesis and Game Gear (among others). We'll extract the ROMs from each collection and then compare these GameCube collections to modern SEGA game collections like Sonic Origins Plus and the Genesis collection for Nintendo Switch Online. How many RSS subscribers do I have? RSS is super rad way to consume internet content (“ like a newspaper ”). This blog gets syndicated via RSS and an email newsletter. Unlike with my newsletter, it's not clear how many people are reading my blog using RSS compared to my newsletter. That's a good thing, privacy is important and I don't need to know who you are to enjoy my blog :) But what if I was interested in a rough number of subscribers to the RSS feed? What first-party GameCube titles are available on Nintendo Switch Online? Nintendo just announced that the GameCube game “Chibi Robo!” would be coming in exactly one week to Nintendo Switch Online + Expansion Pack (NSO+). Chibi Robo is known for being a hidden gem in the GameCube library, and thus quite expensive to obtain a physical copy. This made me think about what other games Nintendo had announced for NSO+ “GameCube Classics” , and I noticed an interesting trend... Many of the most expensive first-party GameCube titles are either planned or already available on NSO+. Transferring “UTF8.XYZ” I'm transferring the UTF8.XYZ domain and service to Trey Hunner , a friend and beloved member of the Python community. Trey and I have talked about making this transfer many times at PyCon US's across the years, and now it's finally happening! Extracting 20+ NES & Famicom ROMs from Animal Crossing Animal Crossing for the GameCube was a game far ahead of its time and one of my personal favorites growing up. One of the most beloved features was the addition of playable NES games as rare collectible furniture items. This feature was implemented by including NES and Famicom Disk System emulators and the actual game ROMs on the Animal Crossing disk. The NES emulator included with Animal Crossing is frequently referenced as being one of the most accurate NES emulators available, but comes with the requirement of playing or emulating a GameCube to access the feature. Nintendo Switch 2 physical game price differences Last week I was able to purchase a Nintendo Switch 2. The console was due to arrive on Monday, so I also picked up a physical copy of Mario Kart World for $80 USD (compared to $70 USD for digital). This is the first time I can remember that Nintendo had a different price for an identical game, just based on the medium. At first glance this seems like a $10 USD difference, but there's a detail that gets obscured by comparing sticker price alone: who is paying storage costs. Email has algorithmic curation, too Communication technologies should optimally be reliable, especially when both parties have opted-in to consistent reliable delivery. I don't want someone else to decide whether I receive a text message or email from a friend. I associate "algorithmic curation" with social media platforms like TikTok, YouTube, Twitter, or Instagram. I don't typically think about email as a communication technology that contains algorithmic curation. Maybe that thinking should change? Setting Discord status from physical GameCube console Have you ever seen one of your friends playing a game or listening to music in their Discord “status”? That feature is called “ Rich Presence ”. What if you want to show your Discord friends that you're playing your GameCube? and I don't mean an emulator like Dolphin , I'm talking about a physical console from 2001. Open Source Security work isn't “Special” To understand why security is special, we have to take a look at why open source is an amazing thing. For many components of open source, users that have the time, desire, and expertise are able to contribute meaningfully to projects. As a maintainer of an open source project, this is awesome! Hand-drawn QR codes I really like QR codes. Recently I purchased a new sticky-note-like pad from a new local stationery store in Minneapolis . The sheets have a 10x10 grid and 2x10 grid. UN Open Source Week 2025: Security for the Long-Haul This page was used during the United Nations Open Source Week "Maintain-a-thon" hosted by the Sovereign Tech Agency and Alpha Omega . Thanks to both the Sovereign Tech Agency and Alpha Omega for supporting my attendance at this event and Alpha Omega for supporting security in the Python ecosystem. Pikmin 2 International Treasure Hoard (DONE) Pikmin 2 is a game about collecting "treasure" from Earth in the form of mostly human-made products and items. One of the distinguishing features of the game is that the treasures sometimes model real-life brands like Duracell and Dr. Pepper . Pikmin 2 has three distinct regional treasure hoards , each with unique treasures: US, JP, and PAL.

Report Abuse Arunava Modak Posted on Nov 14, 2021 React Router V5 vs V6 # webdev # javascript # react # reactrouter React Router version 6 was released recently, and it is important for us to understand the changes as it is one of the most widely used react libraries out there. So What Is React Router ? React Router is a fully-featured client and server-side routing library for React, a JavaScript library for building user interfaces. React Router runs anywhere React runs; on the web, on the server with node.js, and on React Native. In V6, there has been a lot of under the hood changes, be it an enhanced path pattern matching algorithm or addition of new components. Not only that but the bundle size has been reduced by almost 58%. So here are some of the changes you can make to upgrade an existing project from React Router v5 to v6. Switch Replaced With Routes In v6, Switch in not exported from react-router-dom . In the earlier version we could use Switch to wrap our routes. Now we use Routes to do the same thing instead of Switch . Changes In The Way We Define Our Route The component that should be rendered on matching a route can not be written as children of the Route component, but it takes a prop called element where we have to pass a JSX component for that to be rendered. The exact Prop Is Not Needed Anymore With version 6, React Router has just become alot more awesome. The now better, path matching algorithm, enables us to match a particular route match without the exact prop. Earlier, without exact , any URL starting with the concerned keyword would be loaded, as the matching process was done from top to down the route definitions. But now, we do not have to worry about that, as React Router has a better algorithm for loading the best route for a particular URL, the order of defining does not really matters now. So, to sum up these three points we can consider this code snippet. In v5 import { Switch , Route } from " react-router-dom " ; . . . < Switch > < Route path = " / " > < Home /> < /Route > < Route exact path = " /cryptocurrencies " > < Cryptocurrencies /> < /Route > < Route exact path = " /crypto/:coinId " > < CryptoDetails /> < /Route > < Route exact path = " /exchanges " > < Exchanges /> < /Route > < /Switch > Enter fullscreen mode Exit fullscreen mode In v6 import { Routes , Route } from " react-router-dom " ; . . . < Routes > < Route path = " / " element = { < Home /> } / > < Route path = " /crypto/:coinId " element = { < CryptoDetails /> } / > < Route path = " /cryptocurrencies " element = { < Cryptocurrencies /> } / > < Route path = " /exchanges " element = { < Exchanges /> } / > < /Routes > Enter fullscreen mode Exit fullscreen mode No Need To Install react-router-config Seperately react-router-config allowed us to define our routes as javascript objects, instead of React elements, and all it's functionalities have to moved in the core react router v6. //V5 import { renderRoutes } from " react-router-config " ; const routes = [ { path : " / " , exact : true , component : Home }, { path : " /cryptocurrencies " , exact : true , component : Cryptocurrencies }, { path : " /exchanges " , exact : true , component : Exchanges } ]; export default function App () { return ( < div > < Router > { renderRoutes ( routes )} < /Router > < /div > ); } //V6 function App () { let element = useRoutes ([ // These are the same as the props you provide to <Route> { path : " / " , element : < Home /> }, { path : " /cryptocurrencies " , element : < Cryptocurrencies /> , // Nested routes use a children property children : [ { path : " :coinId " , element : < CryptoDetails /> }, ] }, { path : " /exchanges " , element : < Exchanges /> }, ]); // The returned element will render the entire element // hierarchy with all the appropriate context it needs return element ; } Enter fullscreen mode Exit fullscreen mode useHistory Is Now useNavigate React Router v6 now has the navigate api, which most of the times would mean replacing useHistory to useNavigate . //V5 import { useHistory } from " react-router-dom " ; function News () { let history = useHistory (); function handleClick () { history . push ( " /home " ); } return ( < div > < button onClick = {() => { history . push ( " /home " ); }} > Home < /button > < /div > ); } //V6 import { useNavigate } from " react-router-dom " ; function News () { let navigate = useNavigate (); return ( < div > < button onClick = {() => { navigate ( " /home " ); }} > go home < /button > < /div > ); } Enter fullscreen mode Exit fullscreen mode Some more common features of useHistory were go , goBack and goForward . These can also be achieved by navigate api too, we just need to mention the number of steps we want to move forward or backward ('+' for forward and '-' for backward). So we can code these features we can consider this. //V5 import { useHistory } from " react-router-dom " ; function Exchanges () { const { go , goBack , goForward } = useHistory (); return ( <> < button onClick = {() => go ( - 2 )} > 2 steps back < /button > < button onClick = { goBack } > 1 step back < /button > < button onClick = { goForward } > 1 step forward < /button > < button onClick = {() => go ( 2 )} > 2 steps forward < /button > < / > ); } //V6 import { useNavigate } from " react-router-dom " ; function Exchanges () { const navigate = useNavigate (); return ( <> < button onClick = {() => navigate ( - 2 )} > 2 steps back < /button > < button onClick = {() => navigate ( - 1 )} > 1 step back < /button > < button onClick = {() => navigate ( 1 )} > 1 step forward < /button > < button onClick = {() => navigate ( 2 )} > 2 steps forward < /button > < / > ); } Enter fullscreen mode Exit fullscreen mode activeStyle and activeClassName Props Removed From <NavLink /> In the previous version we could set a seperate class or a style object for the time when the <NavLink/> would be active. In V6, these two props are removed, instead in case of Nav Links className and style props, work a bit differently. They take a function which in turn gives up some information about the link, for us to better control the styles. //V5 < NavLink to = " /news " style = {{ color : ' black ' }} activeStyle = {{ color : ' blue ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = " nav-link " activeClassName = " active " > Exchanges < /NavLink > //V6 < NavLink to = " /news " style = {({ isActive }) => { color : isActive ? ' blue ' : ' black ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = {({ isActive }) => " nav-link " + ( isActive ? " active " : "" )} > Exchanges < /NavLink > Enter fullscreen mode Exit fullscreen mode Replace Redirect with Navigate Redirect is no longer exported from react-router-dom , instead we use can Navigate to achieve the same features. //V5 import { Redirect } from " react-router-dom " ; < Route exact path = " /latest-news " > < Redirect to = " /news " > < /Route > < Route exact path = " /news " > < News /> < /Route > //V6 import { Navigate } from " react-router-dom " ; < Route path = " /latest-news " element = { < Navigate replace to = " /news " > } / > < Route path = " /news " element = { < Home /> } / > Enter fullscreen mode Exit fullscreen mode Please note the replace prop passed inside the element of the Route . This signifies we are replacing the current navigation stack. Without replace it would mean we are just pushing the component in the existing navigation stack. That's it for today. Hope this helps you upgrading your react project, to React Router V6. Thank you for reading !! 😇😇 Happy Coding !! Happy Building !!

If you want an SPA, you can use React and React Router, which takes care of your client-side routing. For something like Next.js it comes with it's own page based routing, I don't think we can implement SPA.

If you want the tools that Next or Gatsby offer then it makes sense to just go for those. If you're working on a more vanilla React project then you will generally see something like React Router in place to handle the routing.

For instance, with Next when you add a new JS/TS or JSX/TSX file into the pages folder, it will automatically map out the path for you without you having to define it.

Report Abuse Anton Moldovan for NBomber Posted on May 2, 2025 Load Testing Microservices # nbomber # loadtesting # performance # microservices When it comes to load testing microservices, we usually suggest applying two strategies: 1. Simulate User Journeys Across the Entire Application (End-to-End) One effective approach to load testing is simulating real-world user flows that interact with multiple services. These end-to-end tests replicate how users actually use your application—from logging in and browsing, to making purchases or performing other key actions. By executing these flows under load, you can assess how your microservices perform collectively. This helps identify bottlenecks in the orchestration of services, spot resource contention, and evaluate system behavior under realistic conditions. Key Benefits: Understand how services interact under load. Uncover integration or orchestration issues . Test autoscaling configuration to avoid unexpected overloads and ensure your system scales reliably under load. Validate that the system meets performance expectations from a user’s perspective. Downsides: High Infrastructure Cost : Running load tests across the entire system typically requires spinning up all microservices, databases, caches, queues, and other dependencies. This can be resource-intensive, especially if you need to scale components just for the purpose of the test. For big companies this type of tests can lead to significant costs. Slower Feedback Loop : Because of the orchestration involved, these tests take longer to set up, prepare data and run, making them less suitable for fast, iterative development cycles. As a result, your developers might only discover performance degradations at the last moment. Recommendation : We recommend using end-to-end strategy, as it can reveal issues that are difficult to identify when testing microservices in isolation (we explain this in more detail later on this page). However, big companies typically run such tests less frequently — often in preparation for major events like Black Friday or monthly releases. The main reason to run such tests less frequently is due to their cost — depending on the scale of the company, these tests can be expensive to run. For small and medium-sized companies, infrastructure costs may not be an issue — they often utilize their staging environments for this purpose. Usually this type of tests is writen by automation QA engineers, not developers. To write such tests based on user journeys, we recommend using the Closed Model for simulating workload , since the user flow is transactional and modeled as a sequence of dependent steps. 2. Test Individual Microservices in Isolation While end-to-end testing provides a macro view, it’s equally important to test microservices in isolation. This strategy helps you pinpoint which services may struggle with performance independently of the rest of the system. In isolated tests, you can simulate the service's inputs—usually HTTP requests, message queue events, or gRPC calls—and measure how it handles increasing load. This allows you to fine-tune specific services, detect memory leaks, or assess how the service scales independently. Key Benefits: Low infrastructure costs : These tests are usually very easy to set up and run even on developer machine. Fast feedback loop : You can quickly identify performance degradation in a specific service. Isolated tests can be easily integrated into your CI/CD pipeline and treated like regular unit or integration tests. Identify performance bottlenecks within individual services. Downsides: These tests are not fully representative : They typically cover only a single service. The worst-case scenario is when multiple services, each performing well in isolated tests but fail to handle the expected load when run together in a production environment. Recommendation: We recommend using this strategy as it is cheaper than full end-to-end load tests and provides an easy way for developers to run it locally and get quick results. Usually this type of tests are writen by developers and not automation QA engineers. Prioritize services that interact directly with the database . If these services perform well, upstream dependent services will typically also benefit. Database scalability is often the main bottleneck, so it's more effective to focus on services that work directly with the database rather than those that depend on other services in the chain. To write isolated load tests, we recommend using the Open Model for simulating workload . From the perspective of an individual service, it may expose several endpoints that are partially used by different user flows concurrently. At this level, it's simpler to reason about the service in terms of request rate rather than number of concurrent users. Additionally, when defining your SLO/SLA , companies usually focus on metrics like request rate and error rate — so using the Open Model aligns well with these targets. Another important benefit is that the Open Model tends to produce more consistent results, which makes it easier to apply reliable assertion logic. If your microservice depends on other services, especially those outside your ownership, you should consider mocking them. Mocking dependent services is often necessary to isolate the system under test and ensure more reliable and consistent load test results. Make sure your mocked API allows you to configure latency delays and has sufficient throughput capacity (at a minimum, it should be fast enough not to become a bottleneck).

Report Abuse DEV-AI Posted on Oct 27, 2025 Mastering Cloud Storage: How to Mount S3 as a Local Filesystem with Rclone # linux # cli # tutorial # aws Interacting with cloud object storage like Amazon S3 can sometimes feel disconnected from your local environment. While web consoles and APIs are powerful, nothing beats the convenience of accessing remote files as if they were in a local folder. Rclone is a powerful command-line utility that bridges this gap, allowing you to not only sync and manage files across dozens of cloud providers but also to mount them directly into your filesystem. This article provides a comprehensive walkthrough of how to configure rclone for any S3-compatible service, mount it as a local directory with intelligent caching, and configure it as a robust, auto-recovering system service on Linux. Part 1: Initial Rclone Installation and Configuration Before you can mount a bucket, you need to install rclone and teach it how to access your S3 storage. Installing Rclone Rclone offers a simple installation script for Linux and other Unix-like systems. It's the recommended way to ensure you have the latest version [1]. sudo -v ; curl https://rclone.org/install.sh | sudo bash Enter fullscreen mode Exit fullscreen mode For other operating systems like Windows, you can download the appropriate binary from the official rclone website [2]. Configuring Your S3 Remote Rclone uses the concept of "remotes" to store connection details for your various cloud services. The interactive rclone config command makes this setup straightforward [3]. Run rclone config in your terminal. Select n to create a new remote. Give it a memorable name (e.g., my-s3 ). You'll be presented with a long list of storage providers. Choose the option for "Amazon S3 Compliant Storage Providers" [4]. Next, select the specific provider (e.g., "Amazon Web Services (AWS) S3", "Minio", "Ceph", etc.) [3]. If your provider isn't listed, "Any other S3 compatible provider" is a safe choice. Follow the prompts to enter your S3 credentials ( access_key_id and secret_access_key ), the correct region, and the endpoint URL if you are not using AWS. For most prompts, the default values are sufficient. Once you confirm the summary, your remote is ready. You can test it by listing your buckets: rclone lsd my-s3: Part 2: Mounting the Bucket with VFS Caching The rclone mount command is the core of this setup. To make it performant and reliable, you should leverage its Virtual File System (VFS) caching capabilities. This stores a local cache of recently accessed files, reducing latency and API calls. The following command mounts your S3 bucket with a 1GB cache that intelligently manages itself: rclone mount my-s3:your-bucket-name /mnt/s3 \ --allow-other \ --vfs-cache-mode full \ --vfs-cache-max-size 1G \ --vfs-cache-max-age 48h \ --log-file /var/log/rclone.log \ --log-level INFO Enter fullscreen mode Exit fullscreen mode Let's break down these essential flags: my-s3:your-bucket-name : Specifies the remote and bucket to mount. /mnt/s3 : The local directory where the bucket will be accessible. This directory must exist before running the command. --allow-other : Allows other users on the system (besides the one running the command) to see and access the mount. This is crucial for applications like Plex or web servers [5]. You may need to enable the user_allow_other option in /etc/fuse.conf . --vfs-cache-mode full : The most compatible cache mode. It buffers all reads and writes to disk, making the remote storage behave much like a local drive. This is ideal for compatibility with a wide range of applications [6]. --vfs-cache-max-size 1G : Limits the total size of the local VFS cache. When this limit is reached, rclone automatically purges the least recently used files to make space [6]. --vfs-cache-max-age 48h : Evicts files from the cache if they haven't been accessed for the specified duration [6]. --log-file & --log-level : Directs logging output to a file for easier troubleshooting. Part 3: Running as a Systemd Service for Reliability and Recovery Running the mount command from a terminal is fine for temporary access, but for a permanent setup, you need a system service. This ensures the mount starts automatically on boot and, more importantly, restarts automatically if it ever fails. You can create a systemd unit file to manage the rclone mount process [7][5]. Create the Service File : Create a new file at /etc/systemd/system/rclone-mount.service and add the following content. Remember to replace placeholders like your-user , your-group , my-s3 , your-bucket-name , and paths to match your setup. [Unit] Description = Rclone Mount for S3 Bucket (my-s3:your-bucket-name) AssertPathIsDirectory = /mnt/s3 After = network-online.target Wants = network-online.target [Service] Type = notify User = your-user Group = your-group Environment = RCLONE_CONFIG=/home/your-user/.config/rclone/rclone.conf ExecStart = /usr/bin/rclone mount my-s3:your-bucket-name /mnt/s3 \ --allow-other \ --vfs-cache-mode full \ --vfs-cache-max-size 1G \ --vfs-cache-max-age 48h \ --log-file /var/log/rclone.log \ --log-level INFO ExecStop = /bin/fusermount -u /mnt/s3 Restart = always RestartSec = 10 [Install] WantedBy = multi-user.target Understanding the Service File : [Unit] Section : After=network-online.target ensures that rclone only attempts to mount after the network is active, preventing startup errors [7]. [Service] Section : Type=notify : A best practice for rclone . It allows the rclone process to signal systemd once the mount is actually ready [8]. User and Group : Specifies the user and group to run the process under. Running as a non-root user is recommended for security. Environment : Explicitly defines the path to the rclone configuration file, as systemd services run in an isolated environment without access to a user's HOME directory [9]. ExecStart : The full mount command. ExecStop : The command to cleanly unmount the filesystem when the service is stopped [9]. Restart=always & RestartSec=10 : This is the key to automatic recovery. If the rclone process ever crashes or is killed, systemd will automatically try to restart it after a 10-second delay [10][7].

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

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.

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.

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.

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.

These third-party services are not controlled by us. We encourage our users to read the privacy policies of each website and application with which they interact.

(" 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.

https://neon.tech/use-cases/database-per-tenant | One Database per User, Zero Complexity This 250+ engineer team replaced shared staging with isolated database branches for safer deploys Neon Product Database Autoscaling Automatic instance sizing Branching Faster Postgres workflows Bottomless storage With copy-on-write Instant restores Recover TBs in seconds Connection pooler Built-in with pgBouncer Ecosystem Neon API Manage infra, billing, quotas Auth Add authentication Data API PostgREST-compatible Instagres No-signup flow Migration guides Step-by-step What is Neon? Serverless Postgres, by Databricks Solutions Use cases Serverless Apps Autoscale with traffic Multi-TB Scale & restore instantly Database per Tenant Data isolation without overhead Platforms Offer Postgres to your users Dev/Test Production-like environments Agents Build full-stack AI agents For teams Startups Build with Neon Security Compliance & privacy Case studies Explore customer stories Docs Pricing Company Blog About us Careers Contact Discord 20.7k Log In Sign Up One Database per User, Zero Complexity Give every end-user a dedicated Postgres database with full isolation. Meet compliance requirements, eliminate noisy neighbors, and scale without friction. Summary Neon makes it easy to isolate each tenant in their own Postgres database with instance-level isolation, without the cost or complexity this architecture requires on other services (like AWS RDS). No more noisy neighbors - Every customer runs on a separate Neon project, ensuring stable performance and reducing cross-tenant risk. Simplified compliance - Meet strict data privacy and residency requirements with per-tenant isolation and regional project placement. Scale each tenant independently - Neon autoscales compute and storage per customer, without over-provisioning—and scales you down, too. Instant per-customer recovery - If there’s an issue (or a customer request), you can instantly roll back any tenant’s database without affecting the rest of your fleet. API-first management - Provision, scale, and manage all your Neon projects programmatically—one engineer can manage thousands of tenants. Sign up using this link to claim $100 off your first invoice, and follow this guide to get started. Why database-per-user? One of the first design decisions you’ll face when building an application with Postgres is how to organize your multitenancy. For certain use cases, adopting a database-per-tenant approach is the most beneficial: Meet strict data privacy requirements - If you’re operating a B2B SaaS platform with customers in regulated industries, they may require maximum data isolation at the instance level. A database-per-tenant approach allows you to meet these stringent data privacy demands by offering each customer their own isolated database. Comply with regional data regulations - In cases where data regulations require customer data to be stored within specific regions, creating separate databases in each region provides a straightforward path to compliance. Simplify management - If your customers require isolated workflows like backups, PITR, or migrations, database-per-tenant makes these easier to manage without cross-tenant risk. Avoiding noisy neighbors - When customers share an instance, a spike in usage from one tenant can degrade performance for others. Isolating tenants ensures consistent performance. Scaling database-per-user architectures in AWS is not a good idea Managed Postgres services like Amazon RDS weren’t designed for high-volume, database-per-tenant use cases. While you can technically isolate each customer with their own database, doing so at scale becomes operationally and financially unsustainable. There are two common paths teams take—both with major drawbacks: 1. Cramming thousands of databases into a single RDS instance Many teams try to save money by putting all their tenants into one large RDS instance. But this leads to: Single point of failure - If that instance goes down, all of your customers are impacted. Noisy neighbors - Resource-hungry tenants can degrade performance for others sharing the same compute. Complex maintenance - Backups, PITR, monitoring, and upgrades become harder to manage when they're tied to a massive shared instance. Rigid scaling - You can’t scale individual tenants—you have to scale the entire instance, often overpaying for idle capacity. 2. Spinning up one RDS instance per tenant This approach gives you the isolation you’re looking for, but it comes at a steep cost—both in dollars and engineering time. The truth is, RDS was never designed for this kind of architecture: Expensive and wasteful - Each RDS instance has a baseline cost, even when idle. Multiply that across hundreds or thousands of tenants, and your bill quickly becomes unsustainable. Storage also doesn’t scale down: once it grows, you’re stuck paying for it. No dynamic scaling - RDS instances don’t autoscale. Resizing compute often requires manual intervention—and in many cases, downtime. High operational burden - You’ll soon need a dedicated team just to handle instance provisioning, monitoring, patching, and scaling logistics. Even basic tasks become complex at scale. Slow setups - Spinning up a new RDS instance can take minutes, not seconds—far from ideal from the end-user experience. Our customers require their data to live in an isolated database, but implementing this in RDS was cumbersome and expensive Joey Teunissen - CTO at Opusflow Postgres the way multi-tenant SaaS was meant to work Neon reimagines Postgres for modern SaaS. With serverless infrastructure, autoscaling, and scale-to-zero, Neon eliminates the overhead that typically makes database-per-tenant architectures so hard to manage. Each customer lives in their own isolated project, and everything—from provisioning to recovery—is API-driven. You get true instance-level isolation without the cost or complexity of managing thousands of traditional Postgres instances. One project per customer A Neon project is the logical equivalent of an "instance", but without the operational heaviness. Each customer's data is completely isolated You can run independent PITRs for a single tenant without affecting your entire fleet You can deploy projects in specific regions to meet local compliance requirements You avoid noisy neighbors entirely—no resource contention between tenants Scale each tenant independently In RDS, you’d have to choose an instance size and disk allocation up front—and scale manually as usage changes. With Neon, compute autoscales on demand, and storage grows and shrinks automatically. You don’t need to provision compute or storage in advance. Every tenant gets their own resources, and those resources scale automatically based on usage. No manual resizing, no idle waste. No more over-provisioning - Your busiest customers get more power when they need it. Everyone else runs lean—or not at all. Scale to zero when idle - If a tenant isn’t using their database, Neon pauses compute and you pay nothing until they return. Fine-grained control - Set compute limits, quotas, and performance policies per tenant to match their plan or use case. info Keep reading about how compute autoscaling works in Neon. Rollback a single customer in seconds In most managed Postgres services like RDS, restoring a database is a slow, manual process. It typically involves spinning up a new instance from a snapshot, waiting several minutes (or longer), and restoring all databases that lived inside that instance—whether or not they were affected. Neon takes a completely different approach. Thanks to our copy-on-write storage engine, Neon lets you restore databases to any previous moment instantly —with no downtime, no data duplication, and no need to preconfigure backups. You can restore just one customer’s database (project) to any point in time—within seconds. You don’t affect other tenants, because recovery operations are fully isolated. You don’t have to spin up new infrastructure—recovery happens in place, with zero operational overhead. This is especially valuable in B2B SaaS platforms, where customers may request a rollback to a specific date due to data errors, user mistakes, or compliance requirements. With Neon, you can fulfill these requests in seconds—without escalation, without disruption, and without touching the rest of your fleet. info Learn more about how instant restore works in Neon. API-first management Neon was built to help you manage thousands of Postgres databases like they’re one. Every operation—provisioning, configuring, scaling, restoring, deleting—is available via our public API. This enables you to fully automate your database lifecycle and manage a massive tenant fleet with minimal engineering effort. Provision at scale - Create new databases for customers programmatically, in milliseconds, with no infrastructure to manage or pre-allocate. Track usage and enforce limits - Set per-project quotas for storage, compute, and active time to align with your pricing tiers or customer plans. Control costs at the tenant level - Monitor usage and apply automated limits or alerts before tenants exceed plan thresholds. Billing aligned to actual usage - Neon’s pricing is based on consumption—not provisioned capacity—so you only pay for what each tenant uses. One engineer can manage thousands of tenants - With the right automation in place, there's no need for a large DevOps team. Info Explore the Neon API documentation and start building. Data compliance and security When you're building a multi-tenant SaaS platform—especially in regulated industries—data privacy and compliance aren’t optional. With Neon, instance-level isolation is built into the architecture, making it easier to meet the strictest customer and regulatory requirements. True data isolation - Each customer lives in their own Neon project, with completely separate compute and storage. There's no risk of cross-tenant data access or resource contention. Regional project placement - Deploy tenant data in specific geographic regions to meet data residency requirements like GDPR, HIPAA, or industry-specific regulations. Access control at the project level - Assign unique credentials and connection strings per tenant, and manage access on a per-project basis. Audit-friendly recovery workflows - Instant, per-tenant PITR enables precise rollback to any point in time—helping you meet data retention and recovery SLAs. Enterprise-level security - All Neon projects use TLS for connections, and built-in encryption is applied to data at rest and in transit. Info Review our security page for details on compliance, SLAs, and our full security commitments. Development environments To take advantage of database branching workflows for dev/test whithin a project-per-tenant design, create a separate Neon project as your single non-prod environment . The methodology: Load your testing data to the main branch. This main branch acts as the primary source for all dev/test environments (they can be hundreds). To instantly create ephemeral environments, derive child branches from the main branch. These branches are fully isolated resource-wise and already include an up-to-date copy of the testing dataset. They can then be synced with the main branch with just one click. Once the work is complete, ephemeral dev/test environments (child branches) can be deleted automatically via your CI/CD.

Report Abuse DEV-AI Posted on Oct 27, 2025 Mastering Cloud Storage: How to Mount S3 as a Local Filesystem with Rclone # linux # cli # tutorial # aws Interacting with cloud object storage like Amazon S3 can sometimes feel disconnected from your local environment. While web consoles and APIs are powerful, nothing beats the convenience of accessing remote files as if they were in a local folder. Rclone is a powerful command-line utility that bridges this gap, allowing you to not only sync and manage files across dozens of cloud providers but also to mount them directly into your filesystem. This article provides a comprehensive walkthrough of how to configure rclone for any S3-compatible service, mount it as a local directory with intelligent caching, and configure it as a robust, auto-recovering system service on Linux. Part 1: Initial Rclone Installation and Configuration Before you can mount a bucket, you need to install rclone and teach it how to access your S3 storage. Installing Rclone Rclone offers a simple installation script for Linux and other Unix-like systems. It's the recommended way to ensure you have the latest version [1]. sudo -v ; curl https://rclone.org/install.sh | sudo bash Enter fullscreen mode Exit fullscreen mode For other operating systems like Windows, you can download the appropriate binary from the official rclone website [2]. Configuring Your S3 Remote Rclone uses the concept of "remotes" to store connection details for your various cloud services. The interactive rclone config command makes this setup straightforward [3]. Run rclone config in your terminal. Select n to create a new remote. Give it a memorable name (e.g., my-s3 ). You'll be presented with a long list of storage providers. Choose the option for "Amazon S3 Compliant Storage Providers" [4]. Next, select the specific provider (e.g., "Amazon Web Services (AWS) S3", "Minio", "Ceph", etc.) [3]. If your provider isn't listed, "Any other S3 compatible provider" is a safe choice. Follow the prompts to enter your S3 credentials ( access_key_id and secret_access_key ), the correct region, and the endpoint URL if you are not using AWS. For most prompts, the default values are sufficient. Once you confirm the summary, your remote is ready. You can test it by listing your buckets: rclone lsd my-s3: Part 2: Mounting the Bucket with VFS Caching The rclone mount command is the core of this setup. To make it performant and reliable, you should leverage its Virtual File System (VFS) caching capabilities. This stores a local cache of recently accessed files, reducing latency and API calls. The following command mounts your S3 bucket with a 1GB cache that intelligently manages itself: rclone mount my-s3:your-bucket-name /mnt/s3 \ --allow-other \ --vfs-cache-mode full \ --vfs-cache-max-size 1G \ --vfs-cache-max-age 48h \ --log-file /var/log/rclone.log \ --log-level INFO Enter fullscreen mode Exit fullscreen mode Let's break down these essential flags: my-s3:your-bucket-name : Specifies the remote and bucket to mount. /mnt/s3 : The local directory where the bucket will be accessible. This directory must exist before running the command. --allow-other : Allows other users on the system (besides the one running the command) to see and access the mount. This is crucial for applications like Plex or web servers [5]. You may need to enable the user_allow_other option in /etc/fuse.conf . --vfs-cache-mode full : The most compatible cache mode. It buffers all reads and writes to disk, making the remote storage behave much like a local drive. This is ideal for compatibility with a wide range of applications [6]. --vfs-cache-max-size 1G : Limits the total size of the local VFS cache. When this limit is reached, rclone automatically purges the least recently used files to make space [6]. --vfs-cache-max-age 48h : Evicts files from the cache if they haven't been accessed for the specified duration [6]. --log-file & --log-level : Directs logging output to a file for easier troubleshooting. Part 3: Running as a Systemd Service for Reliability and Recovery Running the mount command from a terminal is fine for temporary access, but for a permanent setup, you need a system service. This ensures the mount starts automatically on boot and, more importantly, restarts automatically if it ever fails. You can create a systemd unit file to manage the rclone mount process [7][5]. Create the Service File : Create a new file at /etc/systemd/system/rclone-mount.service and add the following content. Remember to replace placeholders like your-user , your-group , my-s3 , your-bucket-name , and paths to match your setup. [Unit] Description = Rclone Mount for S3 Bucket (my-s3:your-bucket-name) AssertPathIsDirectory = /mnt/s3 After = network-online.target Wants = network-online.target [Service] Type = notify User = your-user Group = your-group Environment = RCLONE_CONFIG=/home/your-user/.config/rclone/rclone.conf ExecStart = /usr/bin/rclone mount my-s3:your-bucket-name /mnt/s3 \ --allow-other \ --vfs-cache-mode full \ --vfs-cache-max-size 1G \ --vfs-cache-max-age 48h \ --log-file /var/log/rclone.log \ --log-level INFO ExecStop = /bin/fusermount -u /mnt/s3 Restart = always RestartSec = 10 [Install] WantedBy = multi-user.target Understanding the Service File : [Unit] Section : After=network-online.target ensures that rclone only attempts to mount after the network is active, preventing startup errors [7]. [Service] Section : Type=notify : A best practice for rclone . It allows the rclone process to signal systemd once the mount is actually ready [8]. User and Group : Specifies the user and group to run the process under. Running as a non-root user is recommended for security. Environment : Explicitly defines the path to the rclone configuration file, as systemd services run in an isolated environment without access to a user's HOME directory [9]. ExecStart : The full mount command. ExecStop : The command to cleanly unmount the filesystem when the service is stopped [9]. Restart=always & RestartSec=10 : This is the key to automatic recovery. If the rclone process ever crashes or is killed, systemd will automatically try to restart it after a 10-second delay [10][7]. [Install] Section : WantedBy=multi-user.target tells systemd to start this service during the normal boot process. Enable and Manage the Service : After creating the file, tell systemd to reload its configuration, then enable and start your new service [11]. # Reload the systemd manager configuration sudo systemctl daemon-reload # Enable the service to start on boot and start it now sudo systemctl enable --now rclone-mount.service # Check the status to ensure it's running without errors sudo systemctl status rclone-mount.service If the status shows "active (running)", your S3 bucket is now mounted at /mnt/s3 and will automatically remount on reboots and recover from failures.

Report Abuse Arunava Modak Posted on Nov 14, 2021 React Router V5 vs V6 # webdev # javascript # react # reactrouter React Router version 6 was released recently, and it is important for us to understand the changes as it is one of the most widely used react libraries out there. So What Is React Router ? React Router is a fully-featured client and server-side routing library for React, a JavaScript library for building user interfaces. React Router runs anywhere React runs; on the web, on the server with node.js, and on React Native. In V6, there has been a lot of under the hood changes, be it an enhanced path pattern matching algorithm or addition of new components. Not only that but the bundle size has been reduced by almost 58%. So here are some of the changes you can make to upgrade an existing project from React Router v5 to v6. Switch Replaced With Routes In v6, Switch in not exported from react-router-dom . In the earlier version we could use Switch to wrap our routes. Now we use Routes to do the same thing instead of Switch . Changes In The Way We Define Our Route The component that should be rendered on matching a route can not be written as children of the Route component, but it takes a prop called element where we have to pass a JSX component for that to be rendered. The exact Prop Is Not Needed Anymore With version 6, React Router has just become alot more awesome. The now better, path matching algorithm, enables us to match a particular route match without the exact prop. Earlier, without exact , any URL starting with the concerned keyword would be loaded, as the matching process was done from top to down the route definitions. But now, we do not have to worry about that, as React Router has a better algorithm for loading the best route for a particular URL, the order of defining does not really matters now. So, to sum up these three points we can consider this code snippet. In v5 import { Switch , Route } from " react-router-dom " ; . . . < Switch > < Route path = " / " > < Home /> < /Route > < Route exact path = " /cryptocurrencies " > < Cryptocurrencies /> < /Route > < Route exact path = " /crypto/:coinId " > < CryptoDetails /> < /Route > < Route exact path = " /exchanges " > < Exchanges /> < /Route > < /Switch > Enter fullscreen mode Exit fullscreen mode In v6 import { Routes , Route } from " react-router-dom " ; . . . < Routes > < Route path = " / " element = { < Home /> } / > < Route path = " /crypto/:coinId " element = { < CryptoDetails /> } / > < Route path = " /cryptocurrencies " element = { < Cryptocurrencies /> } / > < Route path = " /exchanges " element = { < Exchanges /> } / > < /Routes > Enter fullscreen mode Exit fullscreen mode No Need To Install react-router-config Seperately react-router-config allowed us to define our routes as javascript objects, instead of React elements, and all it's functionalities have to moved in the core react router v6. //V5 import { renderRoutes } from " react-router-config " ; const routes = [ { path : " / " , exact : true , component : Home }, { path : " /cryptocurrencies " , exact : true , component : Cryptocurrencies }, { path : " /exchanges " , exact : true , component : Exchanges } ]; export default function App () { return ( < div > < Router > { renderRoutes ( routes )} < /Router > < /div > ); } //V6 function App () { let element = useRoutes ([ // These are the same as the props you provide to <Route> { path : " / " , element : < Home /> }, { path : " /cryptocurrencies " , element : < Cryptocurrencies /> , // Nested routes use a children property children : [ { path : " :coinId " , element : < CryptoDetails /> }, ] }, { path : " /exchanges " , element : < Exchanges /> }, ]); // The returned element will render the entire element // hierarchy with all the appropriate context it needs return element ; } Enter fullscreen mode Exit fullscreen mode useHistory Is Now useNavigate React Router v6 now has the navigate api, which most of the times would mean replacing useHistory to useNavigate . //V5 import { useHistory } from " react-router-dom " ; function News () { let history = useHistory (); function handleClick () { history . push ( " /home " ); } return ( < div > < button onClick = {() => { history . push ( " /home " ); }} > Home < /button > < /div > ); } //V6 import { useNavigate } from " react-router-dom " ; function News () { let navigate = useNavigate (); return ( < div > < button onClick = {() => { navigate ( " /home " ); }} > go home < /button > < /div > ); } Enter fullscreen mode Exit fullscreen mode Some more common features of useHistory were go , goBack and goForward . These can also be achieved by navigate api too, we just need to mention the number of steps we want to move forward or backward ('+' for forward and '-' for backward). So we can code these features we can consider this. //V5 import { useHistory } from " react-router-dom " ; function Exchanges () { const { go , goBack , goForward } = useHistory (); return ( <> < button onClick = {() => go ( - 2 )} > 2 steps back < /button > < button onClick = { goBack } > 1 step back < /button > < button onClick = { goForward } > 1 step forward < /button > < button onClick = {() => go ( 2 )} > 2 steps forward < /button > < / > ); } //V6 import { useNavigate } from " react-router-dom " ; function Exchanges () { const navigate = useNavigate (); return ( <> < button onClick = {() => navigate ( - 2 )} > 2 steps back < /button > < button onClick = {() => navigate ( - 1 )} > 1 step back < /button > < button onClick = {() => navigate ( 1 )} > 1 step forward < /button > < button onClick = {() => navigate ( 2 )} > 2 steps forward < /button > < / > ); } Enter fullscreen mode Exit fullscreen mode activeStyle and activeClassName Props Removed From <NavLink /> In the previous version we could set a seperate class or a style object for the time when the <NavLink/> would be active. In V6, these two props are removed, instead in case of Nav Links className and style props, work a bit differently. They take a function which in turn gives up some information about the link, for us to better control the styles. //V5 < NavLink to = " /news " style = {{ color : ' black ' }} activeStyle = {{ color : ' blue ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = " nav-link " activeClassName = " active " > Exchanges < /NavLink > //V6 < NavLink to = " /news " style = {({ isActive }) => { color : isActive ? ' blue ' : ' black ' }} > Exchanges < /NavLink > < NavLink to = " /news " className = {({ isActive }) => " nav-link " + ( isActive ? " active " : "" )} > Exchanges < /NavLink > Enter fullscreen mode Exit fullscreen mode Replace Redirect with Navigate Redirect is no longer exported from react-router-dom , instead we use can Navigate to achieve the same features. //V5 import { Redirect } from " react-router-dom " ; < Route exact path = " /latest-news " > < Redirect to = " /news " > < /Route > < Route exact path = " /news " > < News /> < /Route > //V6 import { Navigate } from " react-router-dom " ; < Route path = " /latest-news " element = { < Navigate replace to = " /news " > } / > < Route path = " /news " element = { < Home /> } / > Enter fullscreen mode Exit fullscreen mode Please note the replace prop passed inside the element of the Route . This signifies we are replacing the current navigation stack. Without replace it would mean we are just pushing the component in the existing navigation stack. That's it for today. Hope this helps you upgrading your react project, to React Router V6. Thank you for reading !! 😇😇 Happy Coding !! Happy Building !!

If you want an SPA, you can use React and React Router, which takes care of your client-side routing. For something like Next.js it comes with it's own page based routing, I don't think we can implement SPA.

If you want the tools that Next or Gatsby offer then it makes sense to just go for those. If you're working on a more vanilla React project then you will generally see something like React Router in place to handle the routing.

For instance, with Next when you add a new JS/TS or JSX/TSX file into the pages folder, it will automatically map out the path for you without you having to define it.

Navigation React SDK Integration Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog React SDK Integration OpenAI Open in ChatGPT SDK Integration to enable SuprSend features like Inbox, Preferences, and Webpush into React-based web applications. OpenAI Open in ChatGPT Installation We support 2 SDK’s for react based applications. @suprsend/react-core : This provides context providers and hooks to integrate SuprSend in to your application. If you want to use web-push, user methods, track events or implement your own UI for preferences and inbox by using provided methods, this library is better option. If you want to use any of inbuilt components for inbox or preferences then use @suprsend/react . @suprsend/react : This library is built on top of @suprsend/react-core , so all hooks, context providers and methods that are present in @suprsend/react-core library are also present in this, with addition to that drop-in components like Inbox, NotificationsFeed, Preferences etc are available which comes with UI to ease integration. npm yarn Copy Ask AI npm install @ suprsend / react Integration SuprSendProvider This context provider need to be wrapper around your component in which you want to use SuprSend methods. This is responsible for creating client instance( new SuprSend() ), identify and reset user. You can access the SuprSend client instance using useSuprSendClient hook. This instance contains all methods needed to integrate preferences, webpush, track events and user methods. Example.js TypeDef Copy Ask AI import { SuprSendProvider } from '@suprsend/react' ; function Example () { return ( < SuprSendProvider publicApiKey = { YOUR_KEY } distinctId = { YOUR_DISTINCT_ID } > < MyComponent /> </ SuprSendProvider > ); } Parameter Description publicApiKey public API Key is mandatory field without which error will be thrown by SuprSendProvider. You can get this from SuprSend Dashboard . distinctId Unique identifier to identify a user across platform. If a value is passed SDK will create user and authenticate user. If null value is passed authenticated user’s instance data will be cleared in your application, kind of logout. userToken Mandatory when enhanced security mode is on. This is ES256 JWT token generated in your server-side. Refer docs to create userToken. refreshUserToken This function is called by SDK internally to get new userToken before existing token is expired. The returned JWT token string is used as the new userToken. userAuthenticationHandler This callback will be called after authenticating user internally when you pass distinctId field to give you back the response of user creation API call. host Customise the host url. vapidKey This key is needed only if you are implementing WebPush notifications. You can get it in SuprSend Dashboard —> Vendors —> WebPush swFileName This key is needed only if you are implementing WebPush notifications and want to customise default serviceworker.js file name with your own service worker file name. After implementing the above SuprSendProvider you can be able to use all SuprSend features. useSuprSendClient This hook is used to access internal SuprSend client instance which has all methods related to webpush, preferences, user methods and track event. Use this hook inside child of SuprSendProvider. Example.js Copy Ask AI import { SuprSendProvider , useSuprSendClient } from "@suprsend/react" function Example () { return ( < SuprSendProvider publicApiKey = { YOUR_KEY } distinctId = { YOUR_DISTINCT_ID } > < MyComponent /> </ SuprSendProvider > ); } function MyComponent () { const suprSendClient = useSuprSendClient (); return ( < p onClick = { () => { // suprSendClient.track('testing'); // suprSendClient.user.setEmail(' [email protected] ') // suprSendClient.webpush.registerPush() // suprSendClient.user.preferences.getPreferences() } } > Click Me </ p > ); } useAuthenticateUser This hook is used to get authenticated user anywhere in your application inside SuprSendProvider. This can also be used to check if user is authenticated before calling any method of SuprSend. Example.js Copy Ask AI import { useAuthenticateUser } from '@suprsend/react' ; function MyComponent () { const { authenticatedUser } = useAuthenticateUser (); useEffect (() => { if ( authenticatedUser ) { console . log ( 'User is authenticated' , authenticatedUser ); } }, [ authenticatedUser ]); return < p > Hello world </ p > ; } Was this page helpful?

Report Abuse Vishwark Posted on Jan 9 🚀 Cracking the Frontend System Design Interview: A Top-to-Bottom Guide # frontendsystemdesign # frontend # systemdesign # interview Frontend System Design interviews are no longer just about fetching and displaying data. Whether you are a junior developer or an aspiring senior architect, you need to demonstrate how to build systems that are scalable, secure, and performant . Here is your roadmap to mastering the FSD interview. 1. The Strategy: HLD vs. LLD Interviews generally split into two phases. Knowing which mindset to adopt is half the battle. High-Level Design (HLD): Focuses on broad architecture, infrastructure, and strategy. You are the Senior Architect deciding how a system is made, scaled, and secured. Low-Level Design (LLD): Often called Machine Coding or Component Design . Here, you are the Implementation Specialist breaking down a problem into granular code, component hierarchies, and API contracts. 2. Step 1: Requirement Gathering & Scoping Never jump straight into coding. Start by defining the boundaries of the problem. Functional Requirements (The "What") Determine the core features. Discuss with your interviewer if you are building for the demand side (B2C) or supply side (B2B) . Module-level thinking: Think about User Management, Payments, or Pricing. Feature-level thinking: For an e-commerce app, this includes Search, Product Details, Reviews, and the Cart. Non-Functional Requirements (The "How") This is where you boost performance and UX. Environment: Is it responsive (all devices) or adaptive (specific resolutions)? Performance: Discuss asset optimization (JS/CSS/Images) and Web Vitals (FCP, LCP, TTI). Security: Mention Authentication, Authorization, and Content Security Policy (CSP). 💡 Pro-Tip: Prioritize your requirements into P0, P1, and P2 tiers to define your Minimum Viable Product (MVP) . 3. Step 2: Strategic Tech Stack Choices For senior roles, saying "I use React because I like it" isn't enough. You must evaluate the best fit for the market and the team's skillset . Frameworks: React, Vue, or Angular based on project needs. State Management: Redux, Context API, or even client-side databases like IndexedDB . Build Tools: Choosing between Vite, Webpack, Rollup, or Parcel for bundling. Architecture: Will you use a Monorepo or a Micro-frontend setup? 4. Step 3: Component Architecture (LLD) Break the big problem into small, reusable pieces. Hierarchy: Map out how components (Search, Listing, Rating, Buttons) sit within each other. Data Sharing: How will components communicate? How will you share data between routes while utilizing caching? Generic Components: Aim for "Dumb" or abstract components that can be reused by multiple consumers with different themes or layouts. 5. Step 4: Data, APIs, and Protocols Define the "contract" between the frontend and the backend. Protocols: Will you use REST, GraphQL, Server-Sent Events (SSE) , or Socket/RPC ? Data Modeling: Don't just talk about successful data; talk about Error Handling . Use proper status codes (4xx for client errors, 5xx for server errors) to provide context without revealing sensitive info. Implementation Details: Mention advanced patterns like Infinite Scroll (using Intersection Observer), Debouncing , Throttling , and Abort Controllers for API cancellations. 6. Tools to Speed Up Your Design In an online interview, being productive with your drawing tools is essential. Practice with: Excalidraw / Zenboard (Great for freehand and slides). Draw.io / Lucidchart (Excellent for flow diagrams). Miro (Collaborative whiteboarding). 7. The "Interview Mantras" 🧘♂️ To truly crack the round, remember these four rules: Don't be "Pushpa": Don't just recite things you studied; keep checking in with the interviewer to see what they want to focus on. Keep Talking: The interviewer needs to gauge your thought process and how you make decisions. One Problem at a Time: Don't jump between too many topics. Pick one, get into the details, and finalize the approach before moving on. Practice Mock Designs: Do 2-3 full HLD/LLD runs before the actual interview to get comfortable with the tools and timing. Final Thought Frontend System Design is a combination of product sense, UX design, and deep technical engineering. It's no longer just about the UI; it's about the "backend of the frontend". Happy Designing! 💻✨ Analogy: Building a frontend system is like planning a city . HLD is the master plan—where the highways and power grids go so the city can scale. LLD is the blueprint for a single house—the plumbing, the wiring, and the specific materials that make that one unit functional.

It is available on all modern Unix systems, Windows, MacOS, and probably additional platforms. Note Some behavior may be platform dependent, since calls are made to the operating system socket APIs. Availability : not WASI. This module does not work or is not available on WebAssembly. See WebAssembly platforms for more information. The Python interface is a straightforward transliteration of the Unix system call and library interface for sockets to Python’s object-oriented style: the socket() function returns a socket object whose methods implement the various socket system calls. Parameter types are somewhat higher-level than in the C interface: as with read() and write() operations on Python files, buffer allocation on receive operations is automatic, and buffer length is implicit on send operations. See also Module socketserver Classes that simplify writing network servers. Module ssl A TLS/SSL wrapper for socket objects. Socket families ¶ Depending on the system and the build options, various socket families are supported by this module. The address format required by a particular socket object is automatically selected based on the address family specified when the socket object was created. Socket addresses are represented as follows: The address of an AF_UNIX socket bound to a file system node is represented as a string, using the file system encoding and the 'surrogateescape' error handler (see PEP 383 ). An address in Linux’s abstract namespace is returned as a bytes-like object with an initial null byte; note that sockets in this namespace can communicate with normal file system sockets, so programs intended to run on Linux may need to deal with both types of address. A string or bytes-like object can be used for either type of address when passing it as an argument. Changed in version 3.3: Previously, AF_UNIX socket paths were assumed to use UTF-8 encoding. Changed in version 3.5: Writable bytes-like object is now accepted. A pair (host, port) is used for the AF_INET address family, where host is a string representing either a hostname in internet domain notation like 'daring.cwi.nl' or an IPv4 address like '100.50.200.5' , and port is an integer. For IPv4 addresses, two special forms are accepted instead of a host address: '' represents INADDR_ANY , which is used to bind to all interfaces, and the string '<broadcast>' represents INADDR_BROADCAST . This behavior is not compatible with IPv6, therefore, you may want to avoid these if you intend to support IPv6 with your Python programs. For AF_INET6 address family, a four-tuple (host, port, flowinfo, scope_id) is used, where flowinfo and scope_id represent the sin6_flowinfo and sin6_scope_id members in struct sockaddr_in6 in C. For socket module methods, flowinfo and scope_id can be omitted just for backward compatibility. Note, however, omission of scope_id can cause problems in manipulating scoped IPv6 addresses. Changed in version 3.7: For multicast addresses (with scope_id meaningful) address may not contain %scope_id (or zone id ) part. This information is superfluous and may be safely omitted (recommended). AF_NETLINK sockets are represented as pairs (pid, groups) . Linux-only support for TIPC is available using the AF_TIPC address family. TIPC is an open, non-IP based networked protocol designed for use in clustered computer environments. Addresses are represented by a tuple, and the fields depend on the address type. The general tuple form is (addr_type, v1, v2, v3 [, scope]) , where: addr_type is one of TIPC_ADDR_NAMESEQ , TIPC_ADDR_NAME , or TIPC_ADDR_ID . scope is one of TIPC_ZONE_SCOPE , TIPC_CLUSTER_SCOPE , and TIPC_NODE_SCOPE . If addr_type is TIPC_ADDR_NAME , then v1 is the server type, v2 is the port identifier, and v3 should be 0. If addr_type is TIPC_ADDR_NAMESEQ , then v1 is the server type, v2 is the lower port number, and v3 is the upper port number. If addr_type is TIPC_ADDR_ID , then v1 is the node, v2 is the reference, and v3 should be set to 0. A tuple (interface, ) is used for the AF_CAN address family, where interface is a string representing a network interface name like 'can0' . The network interface name '' can be used to receive packets from all network interfaces of this family. CAN_ISOTP protocol require a tuple (interface, rx_addr, tx_addr) where both additional parameters are unsigned long integer that represent a CAN identifier (standard or extended). CAN_J1939 protocol require a tuple (interface, name, pgn, addr) where additional parameters are 64-bit unsigned integer representing the ECU name, a 32-bit unsigned integer representing the Parameter Group Number (PGN), and an 8-bit integer representing the address. A string or a tuple (id, unit) is used for the SYSPROTO_CONTROL protocol of the PF_SYSTEM family. The string is the name of a kernel control using a dynamically assigned ID. The tuple can be used if ID and unit number of the kernel control are known or if a registered ID is used. Added in version 3.3. AF_BLUETOOTH supports the following protocols and address formats: BTPROTO_L2CAP accepts a tuple (bdaddr, psm[, cid[, bdaddr_type]]) where: bdaddr is a string specifying the Bluetooth address. psm is an integer specifying the Protocol/Service Multiplexer. cid is an optional integer specifying the Channel Identifier. If not given, defaults to zero. bdaddr_type is an optional integer specifying the address type; one of BDADDR_BREDR (default), BDADDR_LE_PUBLIC , BDADDR_LE_RANDOM . Changed in version 3.14: Added cid and bdaddr_type fields. BTPROTO_RFCOMM accepts (bdaddr, channel) where bdaddr is the Bluetooth address as a string and channel is an integer. BTPROTO_HCI accepts a format that depends on your OS. On Linux it accepts an integer device_id or a tuple (device_id, [channel]) where device_id specifies the number of the Bluetooth device, and channel is an optional integer specifying the HCI channel ( HCI_CHANNEL_RAW by default). On FreeBSD, NetBSD and DragonFly BSD it accepts bdaddr where bdaddr is the Bluetooth address as a string. Changed in version 3.2: NetBSD and DragonFlyBSD support added. Changed in version 3.13.3: FreeBSD support added. Changed in version 3.14: Added channel field. device_id not packed in a tuple is now accepted. BTPROTO_SCO accepts bdaddr where bdaddr is the Bluetooth address as a string or a bytes object. (ex. '12:23:34:45:56:67' or b'12:23:34:45:56:67' ) Changed in version 3.14: FreeBSD support added. AF_ALG is a Linux-only socket based interface to Kernel cryptography. An algorithm socket is configured with a tuple of two to four elements (type, name [, feat [, mask]]) , where: type is the algorithm type as string, e.g. aead , hash , skcipher or rng . name is the algorithm name and operation mode as string, e.g. sha256 , hmac(sha256) , cbc(aes) or drbg_nopr_ctr_aes256 . feat and mask are unsigned 32bit integers. Availability : Linux >= 2.6.38. Some algorithm types require more recent Kernels. Added in version 3.6. AF_VSOCK allows communication between virtual machines and their hosts. The sockets are represented as a (CID, port) tuple where the context ID or CID and port are integers. Availability : Linux >= 3.9 See vsock(7) Added in version 3.7. AF_PACKET is a low-level interface directly to network devices. The addresses are represented by the tuple (ifname, proto[, pkttype[, hatype[, addr]]]) where: ifname - String specifying the device name. proto - The Ethernet protocol number. May be ETH_P_ALL to capture all protocols, one of the ETHERTYPE_* constants or any other Ethernet protocol number. pkttype - Optional integer specifying the packet type: PACKET_HOST (the default) - Packet addressed to the local host. PACKET_BROADCAST - Physical-layer broadcast packet. PACKET_MULTICAST - Packet sent to a physical-layer multicast address. PACKET_OTHERHOST - Packet to some other host that has been caught by a device driver in promiscuous mode. PACKET_OUTGOING - Packet originating from the local host that is looped back to a packet socket. hatype - Optional integer specifying the ARP hardware address type. addr - Optional bytes-like object specifying the hardware physical address, whose interpretation depends on the device. Availability : Linux >= 2.2. AF_QIPCRTR is a Linux-only socket based interface for communicating with services running on co-processors in Qualcomm platforms. The address family is represented as a (node, port) tuple where the node and port are non-negative integers. Availability : Linux >= 4.7. Added in version 3.8. IPPROTO_UDPLITE is a variant of UDP which allows you to specify what portion of a packet is covered with the checksum. It adds two socket options that you can change. self.setsockopt(IPPROTO_UDPLITE, UDPLITE_SEND_CSCOV, length) will change what portion of outgoing packets are covered by the checksum and self.setsockopt(IPPROTO_UDPLITE, UDPLITE_RECV_CSCOV, length) will filter out packets which cover too little of their data. In both cases length should be in range(8, 2**16, 8) . Such a socket should be constructed with socket(AF_INET, SOCK_DGRAM, IPPROTO_UDPLITE) for IPv4 or socket(AF_INET6, SOCK_DGRAM, IPPROTO_UDPLITE) for IPv6. Availability : Linux >= 2.6.20, FreeBSD >= 10.1 Added in version 3.9. AF_HYPERV is a Windows-only socket based interface for communicating with Hyper-V hosts and guests. The address family is represented as a (vm_id, service_id) tuple where the vm_id and service_id are UUID strings. The vm_id is the virtual machine identifier or a set of known VMID values if the target is not a specific virtual machine. Known VMID constants defined on socket are: HV_GUID_ZERO HV_GUID_BROADCAST HV_GUID_WILDCARD - Used to bind on itself and accept connections from all partitions. HV_GUID_CHILDREN - Used to bind on itself and accept connection from child partitions. HV_GUID_LOOPBACK - Used as a target to itself. HV_GUID_PARENT - When used as a bind accepts connection from the parent partition. When used as an address target it will connect to the parent partition. The service_id is the service identifier of the registered service. Added in version 3.12. If you use a hostname in the host portion of IPv4/v6 socket address, the program may show a nondeterministic behavior, as Python uses the first address returned from the DNS resolution. The socket address will be resolved differently into an actual IPv4/v6 address, depending on the results from DNS resolution and/or the host configuration. For deterministic behavior use a numeric address in host portion. All errors raise exceptions. The normal exceptions for invalid argument types and out-of-memory conditions can be raised. Errors related to socket or address semantics raise OSError or one of its subclasses. Non-blocking mode is supported through setblocking() . A generalization of this based on timeouts is supported through settimeout() . Module contents ¶ The module socket exports the following elements. Exceptions ¶ exception socket. error ¶ A deprecated alias of OSError . Changed in version 3.3: Following PEP 3151 , this class was made an alias of OSError . exception socket. herror ¶ A subclass of OSError , this exception is raised for address-related errors, i.e. for functions that use h_errno in the POSIX C API, including gethostbyname_ex() and gethostbyaddr() . The accompanying value is a pair (h_errno, string) representing an error returned by a library call. h_errno is a numeric value, while string represents the description of h_errno , as returned by the hstrerror() C function. Changed in version 3.3: This class was made a subclass of OSError . exception socket. gaierror ¶ A subclass of OSError , this exception is raised for address-related errors by getaddrinfo() and getnameinfo() . The accompanying value is a pair (error, string) representing an error returned by a library call. string represents the description of error , as returned by the gai_strerror() C function. The numeric error value will match one of the EAI_* constants defined in this module. Changed in version 3.3: This class was made a subclass of OSError . exception socket. timeout ¶ A deprecated alias of TimeoutError . A subclass of OSError , this exception is raised when a timeout occurs on a socket which has had timeouts enabled via a prior call to settimeout() (or implicitly through setdefaulttimeout() ). The accompanying value is a string whose value is currently always “timed out”. Changed in version 3.3: This class was made a subclass of OSError . Changed in version 3.10: This class was made an alias of TimeoutError . Constants ¶ The AF_* and SOCK_* constants are now AddressFamily and SocketKind IntEnum collections. Added in version 3.4. socket. AF_UNIX ¶ socket. AF_INET ¶ socket. AF_INET6 ¶ These constants represent the address (and protocol) families, used for the first argument to socket() . If the AF_UNIX constant is not defined then this protocol is unsupported. More constants may be available depending on the system. socket. AF_UNSPEC ¶ AF_UNSPEC means that getaddrinfo() should return socket addresses for any address family (either IPv4, IPv6, or any other) that can be used. socket. SOCK_STREAM ¶ socket. SOCK_DGRAM ¶ socket. SOCK_RAW ¶ socket. SOCK_RDM ¶ socket. SOCK_SEQPACKET ¶ These constants represent the socket types, used for the second argument to socket() . More constants may be available depending on the system. (Only SOCK_STREAM and SOCK_DGRAM appear to be generally useful.) socket. SOCK_CLOEXEC ¶ socket. SOCK_NONBLOCK ¶ These two constants, if defined, can be combined with the socket types and allow you to set some flags atomically (thus avoiding possible race conditions and the need for separate calls). See also Secure File Descriptor Handling for a more thorough explanation. Availability : Linux >= 2.6.27. Added in version 3.2. SO_* socket. SOMAXCONN ¶ MSG_* SOL_* SCM_* IPPROTO_* IPPORT_* INADDR_* IP_* IPV6_* EAI_* AI_* NI_* TCP_* Many constants of these forms, documented in the Unix documentation on sockets and/or the IP protocol, are also defined in the socket module. They are generally used in arguments to the setsockopt() and getsockopt() methods of socket objects. In most cases, only those symbols that are defined in the Unix header files are defined; for a few symbols, default values are provided. Changed in version 3.6: SO_DOMAIN , SO_PROTOCOL , SO_PEERSEC , SO_PASSSEC , TCP_USER_TIMEOUT , TCP_CONGESTION were added. Changed in version 3.6.5: Added support for TCP_FASTOPEN , TCP_KEEPCNT on Windows platforms when available. Changed in version 3.7: TCP_NOTSENT_LOWAT was added. Added support for TCP_KEEPIDLE , TCP_KEEPINTVL on Windows platforms when available. Changed in version 3.10: IP_RECVTOS was added. Added TCP_KEEPALIVE . On MacOS this constant can be used in the same way that TCP_KEEPIDLE is used on Linux. Changed in version 3.11: Added TCP_CONNECTION_INFO . On MacOS this constant can be used in the same way that TCP_INFO is used on Linux and BSD. Changed in version 3.12: Added SO_RTABLE and SO_USER_COOKIE . On OpenBSD and FreeBSD respectively those constants can be used in the same way that SO_MARK is used on Linux. Also added missing TCP socket options from Linux: TCP_MD5SIG , TCP_THIN_LINEAR_TIMEOUTS , TCP_THIN_DUPACK , TCP_REPAIR , TCP_REPAIR_QUEUE , TCP_QUEUE_SEQ , TCP_REPAIR_OPTIONS , TCP_TIMESTAMP , TCP_CC_INFO , TCP_SAVE_SYN , TCP_SAVED_SYN , TCP_REPAIR_WINDOW , TCP_FASTOPEN_CONNECT , TCP_ULP , TCP_MD5SIG_EXT , TCP_FASTOPEN_KEY , TCP_FASTOPEN_NO_COOKIE , TCP_ZEROCOPY_RECEIVE , TCP_INQ , TCP_TX_DELAY . Added IP_PKTINFO , IP_UNBLOCK_SOURCE , IP_BLOCK_SOURCE , IP_ADD_SOURCE_MEMBERSHIP , IP_DROP_SOURCE_MEMBERSHIP . Changed in version 3.13: Added SO_BINDTOIFINDEX . On Linux this constant can be used in the same way that SO_BINDTODEVICE is used, but with the index of a network interface instead of its name.

SHUT_RDWR ¶ These constants are used by the shutdown() method of socket objects. Availability : not WASI. Functions ¶ Creating sockets ¶ The following functions all create socket objects . class socket. socket ( family = AF_INET , type = SOCK_STREAM , proto = 0 , fileno = None ) ¶ Create a new socket using the given address family, socket type and protocol number. The address family should be AF_INET (the default), AF_INET6 , AF_UNIX , AF_CAN , AF_PACKET , or AF_RDS . The socket type should be SOCK_STREAM (the default), SOCK_DGRAM , SOCK_RAW or perhaps one of the other SOCK_ constants. The protocol number is usually zero and may be omitted or in the case where the address family is AF_CAN the protocol should be one of CAN_RAW , CAN_BCM , CAN_ISOTP or CAN_J1939 . If fileno is specified, the values for family , type , and proto are auto-detected from the specified file descriptor. Auto-detection can be overruled by calling the function with explicit family , type , or proto arguments. This only affects how Python represents e.g. the return value of socket.getpeername() but not the actual OS resource. Unlike socket.fromfd() , fileno will return the same socket and not a duplicate. This may help close a detached socket using socket.close() . The newly created socket is non-inheritable . Raises an auditing event socket.__new__ with arguments self , family , type , protocol . Changed in version 3.3: The AF_CAN family was added. The AF_RDS family was added. Changed in version 3.4: The CAN_BCM protocol was added. Changed in version 3.4: The returned socket is now non-inheritable. Changed in version 3.7: The CAN_ISOTP protocol was added. Changed in version 3.7: When SOCK_NONBLOCK or SOCK_CLOEXEC bit flags are applied to type they are cleared, and socket.type will not reflect them. They are still passed to the underlying system socket() call. Therefore, sock = socket . socket ( socket . AF_INET , socket . SOCK_STREAM | socket . SOCK_NONBLOCK ) will still create a non-blocking socket on OSes that support SOCK_NONBLOCK , but sock.type will be set to socket.SOCK_STREAM . Changed in version 3.9: The CAN_J1939 protocol was added. Changed in version 3.10: The IPPROTO_MPTCP protocol was added. socket. socketpair ( [ family [ , type [ , proto ] ] ] ) ¶ Build a pair of connected socket objects using the given address family, socket type, and protocol number. Address family, socket type, and protocol number are as for the socket() function above. The default family is AF_UNIX if defined on the platform; otherwise, the default is AF_INET . The newly created sockets are non-inheritable . Changed in version 3.2: The returned socket objects now support the whole socket API, rather than a subset. Changed in version 3.4: The returned sockets are now non-inheritable. Changed in version 3.5: Windows support added. socket. create_connection ( address , timeout = GLOBAL_DEFAULT , source_address = None , * , all_errors = False ) ¶ Connect to a TCP service listening on the internet address (a 2-tuple (host, port) ), and return the socket object. This is a higher-level function than socket.connect() : if host is a non-numeric hostname, it will try to resolve it for both AF_INET and AF_INET6 , and then try to connect to all possible addresses in turn until a connection succeeds. This makes it easy to write clients that are compatible to both IPv4 and IPv6. Passing the optional timeout parameter will set the timeout on the socket instance before attempting to connect. If no timeout is supplied, the global default timeout setting returned by getdefaulttimeout() is used. If supplied, source_address must be a 2-tuple (host, port) for the socket to bind to as its source address before connecting. If host or port are ‘’ or 0 respectively the OS default behavior will be used. When a connection cannot be created, an exception is raised. By default, it is the exception from the last address in the list. If all_errors is True , it is an ExceptionGroup containing the errors of all attempts. Changed in version 3.2: source_address was added. Changed in version 3.11: all_errors was added. socket. create_server ( address , * , family = AF_INET , backlog = None , reuse_port = False , dualstack_ipv6 = False ) ¶ Convenience function which creates a TCP socket bound to address (a 2-tuple (host, port) ) and returns the socket object. family should be either AF_INET or AF_INET6 . backlog is the queue size passed to socket.listen() ; if not specified , a default reasonable value is chosen. reuse_port dictates whether to set the SO_REUSEPORT socket option. If dualstack_ipv6 is true, family is AF_INET6 and the platform supports it the socket will be able to accept both IPv4 and IPv6 connections, else it will raise ValueError . Most POSIX platforms and Windows are supposed to support this functionality. When this functionality is enabled the address returned by socket.getpeername() when an IPv4 connection occurs will be an IPv6 address represented as an IPv4-mapped IPv6 address. If dualstack_ipv6 is false it will explicitly disable this functionality on platforms that enable it by default (e.g. Linux). This parameter can be used in conjunction with has_dualstack_ipv6() : import socket addr = ( "" , 8080 ) # all interfaces, port 8080 if socket . has_dualstack_ipv6 (): s = socket . create_server ( addr , family = socket . AF_INET6 , dualstack_ipv6 = True ) else : s = socket . create_server ( addr ) Note On POSIX platforms the SO_REUSEADDR socket option is set in order to immediately reuse previous sockets which were bound on the same address and remained in TIME_WAIT state. Added in version 3.8. socket. has_dualstack_ipv6 ( ) ¶ Return True if the platform supports creating a TCP socket which can handle both IPv4 and IPv6 connections. Added in version 3.8. socket. fromfd ( fd , family , type , proto = 0 ) ¶ Duplicate the file descriptor fd (an integer as returned by a file object’s fileno() method) and build a socket object from the result. Address family, socket type and protocol number are as for the socket() function above. The file descriptor should refer to a socket, but this is not checked — subsequent operations on the object may fail if the file descriptor is invalid. This function is rarely needed, but can be used to get or set socket options on a socket passed to a program as standard input or output (such as a server started by the Unix inet daemon). The socket is assumed to be in blocking mode. The newly created socket is non-inheritable . Changed in version 3.4: The returned socket is now non-inheritable. socket. fromshare ( data ) ¶ Instantiate a socket from data obtained from the socket.share() method. The socket is assumed to be in blocking mode. Availability : Windows. Added in version 3.3. socket. SocketType ¶ This is a Python type object that represents the socket object type. It is the same as type(socket(...)) . Other functions ¶ The socket module also offers various network-related services: socket. close ( fd ) ¶ Close a socket file descriptor. This is like os.close() , but for sockets. On some platforms (most noticeable Windows) os.close() does not work for socket file descriptors. Added in version 3.7. socket. getaddrinfo ( host , port , family = AF_UNSPEC , type = 0 , proto = 0 , flags = 0 ) ¶ This function wraps the C function getaddrinfo of the underlying system. Translate the host / port argument into a sequence of 5-tuples that contain all the necessary arguments for creating a socket connected to that service. host is a domain name, a string representation of an IPv4/v6 address or None . port is a string service name such as 'http' , a numeric port number or None . By passing None as the value of host and port , you can pass NULL to the underlying C API. The family , type and proto arguments can be optionally specified in order to provide options and limit the list of addresses returned. Pass their default values ( AF_UNSPEC , 0, and 0, respectively) to not limit the results. See the note below for details. The flags argument can be one or several of the AI_* constants, and will influence how results are computed and returned. For example, AI_NUMERICHOST will disable domain name resolution and will raise an error if host is a domain name. The function returns a list of 5-tuples with the following structure: (family, type, proto, canonname, sockaddr) In these tuples, family , type , proto are all integers and are meant to be passed to the socket() function. canonname will be a string representing the canonical name of the host if AI_CANONNAME is part of the flags argument; else canonname will be empty. sockaddr is a tuple describing a socket address, whose format depends on the returned family (a (address, port) 2-tuple for AF_INET , a (address, port, flowinfo, scope_id) 4-tuple for AF_INET6 ), and is meant to be passed to the socket.connect() method. Note If you intend to use results from getaddrinfo() to create a socket (rather than, for example, retrieve canonname ), consider limiting the results by type (e.g. SOCK_STREAM or SOCK_DGRAM ) and/or proto (e.g. IPPROTO_TCP or IPPROTO_UDP ) that your application can handle. The behavior with default values of family , type , proto and flags is system-specific. Many systems (for example, most Linux configurations) will return a sorted list of all matching addresses. These addresses should generally be tried in order until a connection succeeds (possibly tried in parallel, for example, using a Happy Eyeballs algorithm). In these cases, limiting the type and/or proto can help eliminate unsuccessful or unusable connection attempts. Some systems will, however, only return a single address. (For example, this was reported on Solaris and AIX configurations.) On these systems, limiting the type and/or proto helps ensure that this address is usable. Raises an auditing event socket.getaddrinfo with arguments host , port , family , type , protocol . The following example fetches address information for a hypothetical TCP connection to example.org on port 80 (results may differ on your system if IPv6 isn’t enabled): >>> socket . getaddrinfo ( "example.org" , 80 , proto = socket . IPPROTO_TCP ) [(socket.AF_INET6, socket.SOCK_STREAM, 6, '', ('2606:2800:220:1:248:1893:25c8:1946', 80, 0, 0)), (socket.AF_INET, socket.SOCK_STREAM, 6, '', ('93.184.216.34', 80))] Changed in version 3.2: parameters can now be passed using keyword arguments. Changed in version 3.7: for IPv6 multicast addresses, string representing an address will not contain %scope_id part. socket. getfqdn ( [ name ] ) ¶ Return a fully qualified domain name for name . If name is omitted or empty, it is interpreted as the local host. To find the fully qualified name, the hostname returned by gethostbyaddr() is checked, followed by aliases for the host, if available. The first name which includes a period is selected. In case no fully qualified domain name is available and name was provided, it is returned unchanged. If name was empty or equal to '0.0.0.0' , the hostname from gethostname() is returned. socket. gethostbyname ( hostname ) ¶ Translate a host name to IPv4 address format. The IPv4 address is returned as a string, such as '100.50.200.5' . If the host name is an IPv4 address itself it is returned unchanged. See gethostbyname_ex() for a more complete interface. gethostbyname() does not support IPv6 name resolution, and getaddrinfo() should be used instead for IPv4/v6 dual stack support. Raises an auditing event socket.gethostbyname with argument hostname . Availability : not WASI. socket. gethostbyname_ex ( hostname ) ¶ Translate a host name to IPv4 address format, extended interface. Return a 3-tuple (hostname, aliaslist, ipaddrlist) where hostname is the host’s primary host name, aliaslist is a (possibly empty) list of alternative host names for the same address, and ipaddrlist is a list of IPv4 addresses for the same interface on the same host (often but not always a single address). gethostbyname_ex() does not support IPv6 name resolution, and getaddrinfo() should be used instead for IPv4/v6 dual stack support. Raises an auditing event socket.gethostbyname with argument hostname . Availability : not WASI. socket. gethostname ( ) ¶ Return a string containing the hostname of the machine where the Python interpreter is currently executing. Raises an auditing event socket.gethostname with no arguments. Note: gethostname() doesn’t always return the fully qualified domain name; use getfqdn() for that. Availability : not WASI. socket. gethostbyaddr ( ip_address ) ¶ Return a 3-tuple (hostname, aliaslist, ipaddrlist) where hostname is the primary host name responding to the given ip_address , aliaslist is a (possibly empty) list of alternative host names for the same address, and ipaddrlist is a list of IPv4/v6 addresses for the same interface on the same host (most likely containing only a single address). To find the fully qualified domain name, use the function getfqdn() . gethostbyaddr() supports both IPv4 and IPv6. Raises an auditing event socket.gethostbyaddr with argument ip_address . Availability : not WASI. socket. getnameinfo ( sockaddr , flags ) ¶ Translate a socket address sockaddr into a 2-tuple (host, port) . Depending on the settings of flags , the result can contain a fully qualified domain name or numeric address representation in host . Similarly, port can contain a string port name or a numeric port number. For IPv6 addresses, %scope_id is appended to the host part if sockaddr contains meaningful scope_id . Usually this happens for multicast addresses. For more information about flags you can consult getnameinfo(3) . Raises an auditing event socket.getnameinfo with argument sockaddr . Availability : not WASI. socket. getprotobyname ( protocolname ) ¶ Translate an internet protocol name (for example, 'icmp' ) to a constant suitable for passing as the (optional) third argument to the socket() function. This is usually only needed for sockets opened in “raw” mode ( SOCK_RAW ); for the normal socket modes, the correct protocol is chosen automatically if the protocol is omitted or zero. Availability : not WASI. socket. getservbyname ( servicename [ , protocolname ] ) ¶ Translate an internet service name and protocol name to a port number for that service. The optional protocol name, if given, should be 'tcp' or 'udp' , otherwise any protocol will match. Raises an auditing event socket.getservbyname with arguments servicename , protocolname . Availability : not WASI. socket. getservbyport ( port [ , protocolname ] ) ¶ Translate an internet port number and protocol name to a service name for that service. The optional protocol name, if given, should be 'tcp' or 'udp' , otherwise any protocol will match. Raises an auditing event socket.getservbyport with arguments port , protocolname . Availability : not WASI. socket. ntohl ( x ) ¶ Convert 32-bit positive integers from network to host byte order. On machines where the host byte order is the same as network byte order, this is a no-op; otherwise, it performs a 4-byte swap operation. socket. ntohs ( x ) ¶ Convert 16-bit positive integers from network to host byte order. On machines where the host byte order is the same as network byte order, this is a no-op; otherwise, it performs a 2-byte swap operation. Changed in version 3.10: Raises OverflowError if x does not fit in a 16-bit unsigned integer. socket. htonl ( x ) ¶ Convert 32-bit positive integers from host to network byte order. On machines where the host byte order is the same as network byte order, this is a no-op; otherwise, it performs a 4-byte swap operation. socket. htons ( x ) ¶ Convert 16-bit positive integers from host to network byte order. On machines where the host byte order is the same as network byte order, this is a no-op; otherwise, it performs a 2-byte swap operation. Changed in version 3.10: Raises OverflowError if x does not fit in a 16-bit unsigned integer. socket. inet_aton ( ip_string ) ¶ Convert an IPv4 address from dotted-quad string format (for example, ‘123.45.67.89’) to 32-bit packed binary format, as a bytes object four characters in length. This is useful when conversing with a program that uses the standard C library and needs objects of type in_addr , which is the C type for the 32-bit packed binary this function returns. inet_aton() also accepts strings with less than three dots; see the Unix manual page inet(3) for details. If the IPv4 address string passed to this function is invalid, OSError will be raised. Note that exactly what is valid depends on the underlying C implementation of inet_aton() . inet_aton() does not support IPv6, and inet_pton() should be used instead for IPv4/v6 dual stack support. socket. inet_ntoa ( packed_ip ) ¶ Convert a 32-bit packed IPv4 address (a bytes-like object four bytes in length) to its standard dotted-quad string representation (for example, ‘123.45.67.89’). This is useful when conversing with a program that uses the standard C library and needs objects of type in_addr , which is the C type for the 32-bit packed binary data this function takes as an argument. If the byte sequence passed to this function is not exactly 4 bytes in length, OSError will be raised. inet_ntoa() does not support IPv6, and inet_ntop() should be used instead for IPv4/v6 dual stack support. Changed in version 3.5: Writable bytes-like object is now accepted. socket. inet_pton ( address_family , ip_string ) ¶ Convert an IP address from its family-specific string format to a packed, binary format. inet_pton() is useful when a library or network protocol calls for an object of type in_addr (similar to inet_aton() ) or in6_addr . Supported values for address_family are currently AF_INET and AF_INET6 . If the IP address string ip_string is invalid, OSError will be raised. Note that exactly what is valid depends on both the value of address_family and the underlying implementation of inet_pton() . Availability : Unix, Windows. Changed in version 3.4: Windows support added socket. inet_ntop ( address_family , packed_ip ) ¶ Convert a packed IP address (a bytes-like object of some number of bytes) to its standard, family-specific string representation (for example, '7.10.0.5' or '5aef:2b::8' ). inet_ntop() is useful when a library or network protocol returns an object of type in_addr (similar to inet_ntoa() ) or in6_addr . Supported values for address_family are currently AF_INET and AF_INET6 . If the bytes object packed_ip is not the correct length for the specified address family, ValueError will be raised. OSError is raised for errors from the call to inet_ntop() . Availability : Unix, Windows. Changed in version 3.4: Windows support added Changed in version 3.5: Writable bytes-like object is now accepted. socket. CMSG_LEN ( length ) ¶ Return the total length, without trailing padding, of an ancillary data item with associated data of the given length . This value can often be used as the buffer size for recvmsg() to receive a single item of ancillary data, but RFC 3542 requires portable applications to use CMSG_SPACE() and thus include space for padding, even when the item will be the last in the buffer. Raises OverflowError if length is outside the permissible range of values. Availability : Unix, not WASI. Most Unix platforms. Added in version 3.3. socket. CMSG_SPACE ( length ) ¶ Return the buffer size needed for recvmsg() to receive an ancillary data item with associated data of the given length , along with any trailing padding. The buffer space needed to receive multiple items is the sum of the CMSG_SPACE() values for their associated data lengths. Raises OverflowError if length is outside the permissible range of values. Note that some systems might support ancillary data without providing this function. Also note that setting the buffer size using the results of this function may not precisely limit the amount of ancillary data that can be received, since additional data may be able to fit into the padding area. Availability : Unix, not WASI. most Unix platforms. Added in version 3.3. socket. getdefaulttimeout ( ) ¶ Return the default timeout in seconds (float) for new socket objects. A value of None indicates that new socket objects have no timeout. When the socket module is first imported, the default is None . socket. setdefaulttimeout ( timeout ) ¶ Set the default timeout in seconds (float) for new socket objects. When the socket module is first imported, the default is None . See settimeout() for possible values and their respective meanings. socket. sethostname ( name ) ¶ Set the machine’s hostname to name . This will raise an OSError if you don’t have enough rights. Raises an auditing event socket.sethostname with argument name . Availability : Unix, not Android. Added in version 3.3. socket. if_nameindex ( ) ¶ Return a list of network interface information (index int, name string) tuples. OSError if the system call fails. Availability : Unix, Windows, not WASI. Added in version 3.3. Changed in version 3.8: Windows support was added. Note On Windows network interfaces have different names in different contexts (all names are examples): UUID: {FB605B73-AAC2-49A6-9A2F-25416AEA0573} name: ethernet_32770 friendly name: vEthernet (nat) description: Hyper-V Virtual Ethernet Adapter This function returns names of the second form from the list, ethernet_32770 in this example case. socket. if_nametoindex ( if_name ) ¶ Return a network interface index number corresponding to an interface name. OSError if no interface with the given name exists. Availability : Unix, Windows, not WASI. Added in version 3.3. Changed in version 3.8: Windows support was added. See also “Interface name” is a name as documented in if_nameindex() . socket. if_indextoname ( if_index ) ¶ Return a network interface name corresponding to an interface index number. OSError if no interface with the given index exists. Availability : Unix, Windows, not WASI. Added in version 3.3. Changed in version 3.8: Windows support was added. See also “Interface name” is a name as documented in if_nameindex() . socket. send_fds ( sock , buffers , fds [ , flags [ , address ] ] ) ¶ Send the list of file descriptors fds over an AF_UNIX socket sock . The fds parameter is a sequence of file descriptors. Consult sendmsg() for the documentation of these parameters. Availability : Unix, not WASI. Unix platforms supporting sendmsg() and SCM_RIGHTS mechanism. Added in version 3.9. socket. recv_fds ( sock , bufsize , maxfds [ , flags ] ) ¶ Receive up to maxfds file descriptors from an AF_UNIX socket sock . Return (msg, list(fds), flags, addr) . Consult recvmsg() for the documentation of these parameters. Availability : Unix, not WASI. Unix platforms supporting recvmsg() and SCM_RIGHTS mechanism. Added in version 3.9. Note Any truncated integers at the end of the list of file descriptors. Socket Objects ¶ Socket objects have the following methods. Except for makefile() , these correspond to Unix system calls applicable to sockets. Changed in version 3.2: Support for the context manager protocol was added. Exiting the context manager is equivalent to calling close() . socket. accept ( ) ¶ Accept a connection. The socket must be bound to an address and listening for connections. The return value is a pair (conn, address) where conn is a new socket object usable to send and receive data on the connection, and address is the address bound to the socket on the other end of the connection. The newly created socket is non-inheritable . Changed in version 3.4: The socket is now non-inheritable. Changed in version 3.5: If the system call is interrupted and the signal handler does not raise an exception, the method now retries the system call instead of raising an InterruptedError exception (see PEP 475 for the rationale). socket. bind ( address ) ¶ Bind the socket to address . The socket must not already be bound. (The format of address depends on the address family — see above.) Raises an auditing event socket.bind with arguments self , address . Availability : not WASI. socket. close ( ) ¶ Mark the socket closed. The underlying system resource (e.g. a file descriptor) is also closed when all file objects from makefile() are closed. Once that happens, all future operations on the socket object will fail. The remote end will receive no more data (after queued data is flushed). Sockets are automatically closed when they are garbage-collected, but it is recommended to close() them explicitly, or to use a with statement around them. Changed in version 3.6: OSError is now raised if an error occurs when the underlying close() call is made. Note close() releases the resource associated with a connection but does not necessarily close the connection immediately. If you want to close the connection in a timely fashion, call shutdown() before close() . socket. connect ( address ) ¶ Connect to a remote socket at address . (The format of address depends on the address family — see above.) If the connection is interrupted by a signal, the method waits until the connection completes, or raise a TimeoutError on timeout, if the signal handler doesn’t raise an exception and the socket is blocking or has a timeout. For non-blocking sockets, the method raises an InterruptedError exception if the connection is interrupted by a signal (or the exception raised by the signal handler). Raises an auditing event socket.connect with arguments self , address . Changed in version 3.5: The method now waits until the connection completes | 2026-01-13T08:49:04 |

Report Abuse Amber Posted on Jan 4 My First Blog as a Cybersecurity Beginner: Learning Networking with Wireshark. # beginners # networksec # career # education Hey! Its Amber👋 Welcome to my first blog .Let me introduce myself first, I am a second year Computer Science student and passionate about Cybersecurity. Here I will be sharing my personal notes and ideas while I am learning things out myself.As an introvert I hardly ask for mentorship from college professors so the only mentor I got for myself is Chat-GPT.I’m honestly excited (and a little scared) to begin this journey, so yeah — let’s start. Make sure you read till the end 😉. Firstly I started with Networking **because everyone out there said learn networking concepts well if you want to get into cybersecurity so here I am. Learning networking concepts, and along with that, I explored a tool that’s actually used in the industry to capture and analyze network traffic — **Wireshark . .To understand how network traffic analysis work it helped me a lot. Initially I was too confused with protocols and IP addresses So many protocols. So many IP addresses. Packets flying everywhere like chaos. random data in different Colors. but not to lie hands on this tool made it super easy for me to learn networking concepts. Now I could actually see How packets move Which protocol is doing what How communication really happens behind the scenes And in between all this what I realized is "Networking isnt about memorizing protocols, its about understanding the communication". Right now, I’m focusing on: Understanding common protocols (HTTP, TCP, DNS, etc.) Practicing more packet analysis Strengthening my networking basics before jumping deeper into cybersecurity. If you are a beginner like me and feeling overwhelmed by networking or any concept, just know that Confusion is part of the process and You don’t need to understand everything on day one. If you are already into cybersecurity or networking then do let me know Did you start with networking too? Or did you jump straight into security tools? I would love to hear how your journey started.Alright lets just keep it short for my first blog hope you all liked it. Thank You!

Report Abuse Kader Khan Posted on Jan 6 WebRTC P2P vs MCU vs SFU # systemdesign # devops # webrtc # webdev 1. What Is WebRTC (Quick Overview)? WebRTC stands for Web Real-Time Communication — an open standard that enables audio and video streaming directly between browsers and apps without plugins. It’s the foundation of modern video calling on the web because it: 📌 Works in most browsers 📌 Uses real-time protocols (RTP/UDP) for low delay 📌 Secures streams with encryption 📌 Doesn’t require installation of special plugins But at its core, WebRTC is originally designed for peer-to-peer connections — meaning one peer connects directly to another . This is great for 1-to-1 calls , but becomes complicated with more participants. 2. Peer-to-Peer (P2P) ➝ Mesh Architecture 🌐 How P2P works Imagine you and one other person want a video call. WebRTC makes a direct connection between your device and theirs. Both devices send and receive streams directly — no server in the middle. This is ideal for one-to-one video calls : ✔ Low latency ✔ No central server required ✔ No additional cost 🧠 But what if more people join? If you add a third person , each participant must connect with each other : A ↔ B A ↔ C B ↔ C Enter fullscreen mode Exit fullscreen mode That’s 3 connections. If you add a fourth, it becomes more tangled: 6 total connections: A↔B, A↔C, A↔D, B↔C, B↔D, C↔D Enter fullscreen mode Exit fullscreen mode This pattern is called a mesh — each peer connects to all others directly. 📉 Problems with Mesh 🔄 Bandwidth explosion: Each peer must send its video stream to every other peer — quickly saturating upload bandwidth. 🖥 CPU & encoding cost: Each codec needs to encode video multiple times. 🧪 Not reliable when peers > ~4–6 , especially over mobile or slow networks. Thus, mesh works only for very small groups (usually up to ~5 participants). 3. Beyond Mesh — Server-Mediated Architectures To build scalable multi-party calling, we introduce a central media server . This server can relieve peers from uploading to every other peer. There are two major ways to do this: A. SFU — Selective Forwarding Unit 🧠 What SFU does With SFU: Every peer sends their stream once to the server. The SFU forwards streams to all other participants — but it doesn’t decode or re-encode them. Each peer receives the streams it wants and renders them. SFU acts like a traffic hub : one upload from each user, and multiple forwards. 📊 Example Imagine 5 participants: You send your stream _once_ → SFU SFU sends out your video to Bl, B2, B3, B4 → each gets the streams they subscribed to Enter fullscreen mode Exit fullscreen mode Each participant still receives (N-1) streams, but they only upload once . ⭐ Advantages of SFU 📈 Scales better than mesh — because upload cost on the user side doesn’t explode. ⚡ Lower server load — the server just forwards , not processes bits deeply. 🎛 Clients can choose which streams to show (e.g., pin a speaker). 📱 Supports simulcast (multiple quality layers) — better adapts to bandwidth. ⚠ Limitations Still sends multiple streams to each client (could be heavy on download). Server introduces another hop — slightly more latency than direct mesh. B. MCU — Multipoint Control Unit 💡 What MCU does MCU also receives streams from all peers. But unlike SFU, it decodes and mixes them into a single combined stream : ✔ Every participant receives just one stream — no matter how many others are in call. ✔ MCU handles mixing, layout, encoding, and then sends that one stream to all clients. 🎨 Example In a call with 5 users: Each user sends their stream to the MCU. MCU combines all 5 videos into a tiled layout (e.g., a 2×2 grid plus one picture). That single mixed video is sent back to each participant. 💎 Advantages of MCU 📉 Clients receive only one video stream — minimal CPU & bandwidth. 📺 Easy consistent layout for all participants. 📼 Good for legacy devices that can’t handle many streams. 🔥 Downsides 🧠 Very heavy server processing — mixing + encoding is CPU intensive. 💰 Expensive to scale — server resources grow with participants. 😴 Less flexible — clients get one view determined by server (can’t rearrange locally). 4. SFU vs MCU — A Quick Comparison Aspect Mesh (P2P) SFU MCU Server Required ❌ No ✅ Yes ✅ Yes Upload per peer N-1 streams 1 stream 1 stream Download per peer N-1 streams N-1 streams 1 stream Server CPU Load Low Moderate Very High Client CPU Load High Moderate Very Low Scalability Poor High Moderate-High Layout Flexibility High High Low 5. Why SFU Is Dominating Modern Video Apps Today, services like Zoom, Google Meet, Jitsi, and many WebRTC SaaS platforms rely on SFU for group calls because it: ✔ Offers the best balance between scalability and performance ✔ Allows custom layouts and controls ✔ Supports simulcast adaptation to network conditions ✔ Doesn’t overwhelm the server like classic MCU does ([Clan Meeting][2]) MCU is still used for special cases like webinar broadcasting or legacy device support , but SFU is the most widely deployed. 6. Signaling, STUN & TURN — The Supporting Cast Real world WebRTC calls don’t magically connect peers: ✔ Signaling WebRTC uses signaling servers (your app’s backend) to exchange metadata so peers can discover each other and initiate connections. ✔ STUN Helps discover each peer’s public IP address through NAT. ✔ TURN Acts as a relay when direct connection isn’t possible (e.g., firewalls). All of these help establish WebRTC connections before any media is sent. 7. Practical Examples to Visualize 🧑🤝🧑 1-to-1 Call ✔ Mesh / P2P ✔ Direct connection — minimal cost ✔ Best for simple calls 👩👩👦 Small Group (3–6 users) ✔ Mesh still kinda works ✔ But upload & CPU start suffering 🧑💻 Large Group (8–50+ users) ✔ Best with SFU ✔ Each user uploads once, downloads only what they want ✔ Clients can choose video layout 📺 Webinar / Broadcast ✔ MCU or Hybrid ✔ Mixed stream broadcast to many viewers 8. Summary — How WebRTC Makes Video Conferencing Work WebRTC enables real-time audio/video streaming in browsers and apps. For two peers , direct P2P works fine. As participants grow, P2P becomes inefficient (mesh). SFU solves this by forwarding streams through a central server with minimal processing. MCU mixes all media into one stream but at high server cost. Real apps often use hybrid models — e.g., P2P when only 2 users, SFU for groups, and even MCU for broadcasting large sessions.

Navigation Templates Handlebars Helpers Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog Templates Handlebars Helpers OpenAI Open in ChatGPT List of supported handlebars helpers that can be used in a template to format data or add conditions on the data passed in workflow trigger. OpenAI Open in ChatGPT SuprSend template editor uses handlebars templating language to add variables and support conditional content rendering in a template. You can find the list of inbuilt handlebars helpers here . Apart from the inbuilt helper functions, we have also created some custom helper functions which you can use in template editors. Not supported in SMS and Whatsapp: Since, SMS (in India) and Whatsapp require pre-approved templates to send messages, we can’t support conditional content rendering in SMS and Whatsapp templates. You can use handlebars helpers if you are sending SMS in US with vendors like Twilio and Messagebird. default Can be used to add a default value if the variable values are " " , null , undefined . Syntax Copy Ask AI {{ default variable "default_value" }} Returns: Variable value if the variable value is present. For instance, the above example with data {"name":"Joe"} will return Joe Default value if variable value is in " " , null , undefined . For instance, the above example with data {"name":""} , {"name":null} or {"city":"Bangalore"} will return user compare Can be used to show some content in the template based on a condition. For email, you can use display condition to show or hide a particular content block Syntax Example Copy Ask AI {{ #compare name '==' "Mike" }} true_block {{ else }} false_block {{ /compare }} Returns: Returns if the condition inside compare statement returns truthy value. For instance, the above example with data {"candidate_count":1} will return is Returns (in case else statement is present) if the condition inside compare statement returns falsy value. For instance, Example-1 with data {"candidate_count":3} will return are or Returns if the else statement is not present. For instance, Example-2 with data {"candidate_count":3} will not return anything Supported Conditional operators in compare statement: Operator Returns truthy when Sample Statement == LHS equals RHS 1 == “1” === LHS value as well as data type matches with RHS 1 === 1 > LHS is greater than RHS 2 > 1 \< LHS is less than RHS 1 \< 2 >= LHS is greater than equals to RHS 2 >= 2 or 3 >= 2 \<= LHS is less than equal to RHS 2 \<= 2 or 1 \<= 2 != LHS is not equal RHS 3 != 1 !== LHS value or data type does not equal RHS 1 !== “1” Builtin helpers and custom helpers in handlebars can only work with nested objects if the value of parent key is present. For instance, {{default place.city "San Francisco"}} will return "San Francisco" only if place key is present, that is {"place":[]} However, you can use the nested if condition to check if the parent is present and if so, then render nested objects value. Refer below example: Sample text Copy Ask AI {{#if place}} {{default place.city "San Francisco"}} {{else}} San Francisco {{/if}} {{#if person.address}} {{#if person.address.current}} {{{default person.address.current.city "Los Angeles"}} {{/if}} {{/if}} each You can iterate over a static or dynamic length list using each helper. Inside the block, you add the array object key which you want to iterate over. Syntax Mock JSON Data Response Return Copy Ask AI {{ #each array_object }} {{ variable_key }} {{ /each }} Returns: Above example for below mock data will return steve Olivia datetime-format Returns a formatted date string. This helper will throw error if an invalid date is provided. Syntax Mock JSON Data Copy Ask AI {{datetime-format variable "format string" "timezone"}} parameter Obligation description variable mandatory should be a date or timestamp. It will throw an error for invalid date format. To get today’s date (date on which template is getting rendered) you can use "now" string. format string mandatory date string defining the format in which date should be printed. See all formatting options here . e.g. “dddd, MMMM Do YYYY, h:mm:ss a” will return datetime as “Sunday, February 14 2010, 3:25:50 PM” timezone optional you can add timezone as a third parameter to convert time in a given timezone. See the list of all possible timezones here Examples: Example Output {{datetime-format date "ddd, MMM Do YYYY, h:mm:ss a"}} Tue, Sep 26th 2023, 12:00:00 am {{datetime-format date "[Today is] dddd"}} Today is Tuesday {{datetime-format date "Do MMMM, YYYY" "America/Chicago"}} 25th September, 2023 jsonStringify Coverts any type of JSON input to a string. Can be used to print JSON and array directly in templates without having to convert it into individual strings. One of the common use case is to pass complete JSON in Inbox template -> custom JSON field to generate custom UI. Syntax Mock JSON Data Copy Ask AI {{jsonStringify variable}} variable should be a valid JSON input. Examples: Example Output {{jsonStringify this}} \{"likes":3,"comments":4,"users":\["Olivia","Steve"]} {{jsonStringify users}} \["Olivia","Steve"] lowercase This handlebar helper is used to convert string to lowercase. If non string values are provided empty string '' is returned. Syntax Copy Ask AI {{lowercase "string"}} uppercase This handlebar helper is used to convert string to uppercase. If non string values are provided empty string '' is returned. Syntax Copy Ask AI {{uppercase "string"}} capitalize This handlebar helper is used to capitalize the first character in provided string. If non string values are provided empty string '' is returned. Syntax Copy Ask AI {{capitalize "string"}} Math Operators: add Returns the sum of two operands. Both input values should be numbers, else it will throw an error. Syntax Mock JSON Data Copy Ask AI {{add number1 number2}} Examples: Example Output {{add 9 4}} 13 {{add likes comments}} 7 subtract Returns the difference between two operands. Both input values should be numbers, else it will throw an error. Syntax Mock JSON Data Copy Ask AI {{ subtract number1 number2 }} Examples: Example Output {{subtract 9 4}} 5 {{subtract likes 1}} 2 multiply Returns the product of two operands. Both input values should be numbers, else it will throw an error. Syntax Mock JSON Data Copy Ask AI {{ multiply number1 number2 }} Examples: Example Output {{multiply 9 4}} 36 {{multiply ARR billing_months}} 3600 divide Returns the quotient of the left operand divided by the right operand. Both input values should be numbers; else it will throw an error. Syntax Mock JSON Data Copy Ask AI {{ divide dividend divisor }} Examples: Example Output {{divide 14 4}} 3.5 {{divide total_bill billing_months}} 300 round Returns the value of a number rounded to the nearest integer. The input value should be a number; else it will throw an error. Syntax Copy Ask AI {{ round number }} Examples: Example Output {{round 12.5}} 13 {{round (divide 15 4)}} 4 mod Returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend. This helper will throw an error if it encounters an input value that is not a number or if the divisor is 0. Syntax Mock JSON Data Copy Ask AI {{ mod dividend divisor }} Examples: Example Output {{mod 14 4}} 2 {{mod total_bill billing_months}} 0 Array Operators unique Returns unique items in an array. Syntax Mock JSON Data Copy Ask AI {{ unique variable "key_string" }} parameter description variable should be an array. If not helper function will throw an error. key_string mandatory only if items in the array are objects. If a unique operation needs to be performed on nested objects, then object notation (a.b or a[‘b’]) can be used. Examples: Example Output {{unique email }} [email protected] , [email protected] {{unique array "city" }} San Francisco, Austin {{unique personal_details "name.first_name" }} john, mike itemAt Returns item at a particular index in the array. It can be useful in scenarios where you want to display a message like liked by Mike and 3 others . Syntax Mock JSON Data Copy Ask AI {{ itemAt variable index }} Parameter Description variable should be an array else the helper function will throw an error. index should be an integer else the helper function will throw an error. Examples: Example Output {{itemAt email 1}} [email protected] Note: This helper only works with an array of primitive data types like string, boolean, etc. If you have an array with objects in it, you can combine it with a unique helper to return the indexed value of a particular key inside the object. For instance, {{itemAt (unique array "city") 0}} in above mock will return San Francisco . join Concatenates all the values in an array, using a specified separator string between each value. Syntax Mock JSON Data Copy Ask AI {{ join variable "separator" }} Parameter Description variable should be an array and items in the array should be of primitive data types like string, number, etc, else the helper function will throw an error. separator should be string else by default separator , will be used. If not provided , is used. Examples: Example Output {{join email }} [email protected] , [email protected] , [email protected] {{join email ' - '}} [email protected] - [email protected] - [email protected] Note: This helper only works with an array of primitive data types like string, boolean, etc. If you have an array with objects in it, you can combine them with a unique helper to join the value of a particular key inside the object. For instance, {{join (unique array "city")}} in above mock will return San Francisco, Austin length Can be used to get the number of items in an array or the character length of a string. It can be useful in scenarios where you want to display a message like your post has got 100 likes . Syntax Mock JSON Data Copy Ask AI {{ length variable }} Property Description variable should be an array or string to get the actual count of items in the variable provided, else it returns 0. Examples: Example Output {{length array}} 3 {{length name}} 6 {{length active}} 0 We are adding further helpers to this list.

Navigation CORE CONCEPTS Tenants Documentation API Reference Management API CLI Reference Developer Resources Changelog Documentation API Reference Management API CLI Reference Developer Resources Changelog CORE CONCEPTS Tenants OpenAI Open in ChatGPT Learn what tenants stand for and how you can customize notifications for each tenant. OpenAI Open in ChatGPT If you handle communications to end users on behalf of your customers, you might be tasked with handling custom styling in the messages. This can be quite cumbersome if you have to maintain these customisation for every tenant in your codebase. Tenants empower you to send personalized communication on behalf of your customers using a single API. You just have to store tenant guidelines like logo, name, colors, social links and other custom properties for your customers once and then use your tenant variables in templates to dynamically render the template for each of your customer. You can programmatically create / update tenant using either one of our backend SDKs ( Python , Node , Java , Go ) or through SuprSend dashboard. We’ll cover the method to create tenant using SuprSend dashboard. Creating / Updating tenant on SuprSend platform Go to Tenants page from Side Navigation panel. On the tenants page, you’ll see a default tenant created. For every organization, we create a default tenant which represents org level settings like org logo, colors, social links etc. You can create a new tenant by clicking on “New Tenant” button. This will open a form to add tenant id and tenant name . Add the required fields and click on Create tenant Tenant id is a unique identifier for your tenant and can’t be changed once the tenant is created. You’ll have to pass tenant_id in your workflow / event calls to render tenant level customization in your templates. (if no tenant_id is passed, default tenant properties are picked). So, add a tenant_id which is unique and easily identifiable for you. Tenant name can be your customer company / organization name This will open tenant details page. Fill tenant details and Save changes. You can always come back and edit it again later Here are the form fields and its description Field Type Description Tenant ID string of max character length of 64 characters with allowed characters ([a-z0-9_-] that is alphanumeric characters, _ (underscore) and - (hyphen).) tenant_id is used to identify tenant in workflow and event call Tenant Name single line text Name of the company / organization Logo image Tenant logo. Used to render logo in email tenant header Tenant colors 6 digit color code Tenant color settings are mainly used while designing templates. Primary tenant color is used in button, header and footer border in tenant email template. If you don’t provide any of the colors for the tenant, SuprSend will assume you want to use the default values, so color settings will automatically be set to the color settings of default tenant. Social Links URL URLs of social media accounts of the tenant It is used to render social media logos in tenant email footer. if the link is not passed, that logo will not be shown in the footer. Custom Properties JSON Custom properties associated with the tenant. The option to add custom properties is currently not available on the dashboard but you can update it using backend SDK or APIs You can use HTTP API or manage tenants using one of our backend SDKs: Update tenant using python SDK Update tenant using node SDK Update tenant using java SDK Update tenant using go SDK Using tenant components in templates 1. Ready-to-use tenant components in email You can use tenant component in email to add ready-to-use header, footer and buttons in your email template. Tenant component automatically uses tenant logo, social links and primary color to style the email template. You’ll find the tenant component in right side content menu in email editor. You can add tenant component and change block type to switch between header, footer and buttons You can change the component using standard customization options like padding, background color etc. to best suit your email template. 2. Use Tenant variable for all channels You can add tenant variables in all channel templates as $tenant.<property> . e.g., if you have to add tenant_name in your template, you can add it as $tenant.tenant_name . Also, when you type { , tenant variable will automatically come up in auto-suggestions for your to add in the template Triggering notification for your Tenant After adding the tenant variables in your template, you can add tenant_id in your workflow or event trigger to trigger notification for that tenant. This will replace tenant variables with the properties of that tenant at run time. 1. Adding tenant_id in workflow trigger python Node go Copy Ask AI from suprsend import Workflow # Prepare Workflow body workflow_body = { ... } # Add tenant_id in workflow instance wf = Workflow( body = workflow_body, tenant_id = '_tenant_id' ) # Trigger workflow response = supr_client.trigger_workflow(wf) print (response) 2. Adding tenant_id in event trigger python Node go Copy Ask AI from suprsend import Event distinct_id = "distinct_id" # Mandatory, Unique id of user in your application event_name = "event_name" # Mandatory, name of the event you're tracking # Properties: Optional, default=None, a dict representing event-attributes properties = { "key1" : "value1" , "key2" : "value2" } # Add tenant_id in event instance event = Event( distinct_id = distinct_id, event_name = event_name, properties = properties, tenant_id = '_tenant_id_' ) # Track event response = supr_client.track_event(event) print (response) Possible customizations at Tenant Level Custom Template Designs for Each Tenant : You can create unique template designs for each tenant using tenant-specific properties. Refer to the above section for details on how to implement this. Route Tenant messages from their own vendors : You can direct messages through a tenant’s designated vendors by configuring tenant vendors on the vendor settings page. Messages will be sent via the vendor associated with the tenant_id provided in the trigger. If no tenant vendor is set, the system will use the default vendor settings. Tenant level preference setting : Tenants can control what notifications should be sent to their associated users and the their default preference setting. It can be used for cases where admin wants to control the notifications that their teammates receive or when you are sending notifications to multiple tenant’s users and tenant wants to control the notifications their users receive, on which channels and at what frequency.

(" 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 ZedIoT Posted on Dec 31, 2025 Designing an AI Foot Traffic Analysis System for Retail # ai # computervision # systemdesign # retail TL;DR AI foot traffic analysis goes beyond people counting. This article breaks down the system architecture, data flow, and deployment considerations behind modern retail traffic analytics. Why Foot Traffic Analytics Needs AI Traditional foot traffic systems focus on entry and exit counts. While useful, they fail to explain how customers actually move and behave inside a store. AI-driven foot traffic analysis addresses this gap by turning raw video and sensor data into behavioral signals that support operational decisions—such as layout optimization, staffing, and conversion analysis. From a system design perspective, the key challenge is not detection accuracy alone, but building a pipeline that connects perception, analytics, and business context. Core System Components A typical AI foot traffic analysis system consists of several layers working together. 1. Data Collection Layer Retail environments rely on multiple signal sources, including: In-store cameras (ceiling-mounted or zone-specific) IoT sensors for entrances and high-traffic areas POS or transaction context for behavioral correlation These data sources provide the raw inputs required for traffic and movement analysis. 2. AI Detection and Tracking Computer vision models process video streams to: Detect visitors Track movement paths across zones Measure dwell time Avoid duplicate counts in crowded scenarios Multi-object tracking is crucial for maintaining consistent identity signals without storing personal data. 3. Behavior and Traffic Analytics Once detection and tracking are complete, the system generates higher-level insights: Heatmaps for engagement intensity Flow paths between store zones High-traffic, low-conversion areas Dwell-time distributions by zone This layer transforms raw perception data into interpretable metrics. Deployment Considerations: Edge vs Cloud From an engineering standpoint, deployment architecture plays a major role. Edge processing reduces latency and improves privacy by keeping video on-site. Cloud processing supports centralized analytics and cross-store benchmarking. Hybrid models balance scalability with compliance requirements. System designers must account for bandwidth, compute constraints, and privacy regulations when selecting deployment strategies. Turning Analytics into Operational Signals Analytics alone do not create value unless they are operationalized. Well-designed systems expose insights through: Real-time dashboards Alerts for congestion or staffing gaps Historical comparisons across stores and time periods These outputs allow retail teams to link traffic behavior directly to operational decisions. Why Architecture Matters More Than Accuracy In practice, most modern computer vision models achieve acceptable detection accuracy. The real differentiator lies in system architecture: How data flows across layers How insights are integrated into operations How scalable and maintainable the system is over time AI foot traffic analysis succeeds when it is designed as part of a broader retail analytics ecosystem, not as a standalone tool. Final Thoughts AI-driven foot traffic analysis is fundamentally a systems problem. For retail teams and engineers alike, understanding the architecture behind these solutions is critical to building scalable, privacy-aware, and decision-ready analytics platforms.

Report Abuse Prithvi Kumar Detne Posted on Jan 11 AWS DevOps Agent # aws # sre # devops Here’s a comprehensive overview of AWS DevOps Agent —an AI-driven frontier agent from AWS designed to autonomously handle incident response and drive proactive operational excellence: 🔍 What is AWS DevOps Agent? A frontier agent introduced in public preview (from US East–N. Virginia) that autonomously investigates incidents the moment they occur, offering remediation guidance and helping prevent future issues. [aws.amazon.com] , [infoq.com] It acts like a 24/7 on-call engineer that: Builds a topology of your resources (on AWS, hybrid, and multicloud) Gathers telemetry from observability tools (e.g., CloudWatch, Datadog, Splunk) Correlates telemetry, code, and deployment events (via GitHub, GitLab CI/CD) to pinpoint root causes. [aws.amazon.com] , [infoq.com] 🚀 Key Features 1. Autonomous, Always-On Incident Response Automated investigations triggered by alerts, tickets, or alarms; delivers root-cause insights and remediation actions. [aws.amazon.com] , [docs.aws.amazon.com] Interactive incident coordination , routing findings and action plans through Slack, ServiceNow, PagerDuty, and integration with AWS Support. [docs.aws.amazon.com] , [aws.amazon.com] Mitigation plans include actionable steps, validation checks, and rollback options. [aws.amazon.com] , [docs.aws.amazon.com] 2. Proactive Reliability and Preventive Recommendations Analyzes historical incidents to suggest improvements in observability, autoscaling, deployment pipelines, and application resilience. [aws.amazon.com] , [docs.aws.amazon.com] Offers targeted suggestions like configuring Kubernetes HPA for EKS during traffic spikes. [aws.amazon.com] , [docs.aws.amazon.com] 3. Rich Integrations Out-of-the-box with observability platforms: Amazon CloudWatch, Dynatrace, Datadog, New Relic, Splunk. [aws.amazon.com] , [docs.aws.amazon.com] Integrates code and CI/CD pipelines: GitHub, GitLab, GitHub Actions. [aws.amazon.com] , [docs.aws.amazon.com] Extendable via Model Context Protocol (MCP) servers to support custom/internal tools. [aws.amazon.com] , [docs.aws.amazon.com] ⚙️ Architecture & Setup Dual-Console Architecture Admins use the AWS DevOps Agent console to configure Agent Spaces: Define capabilities and integrate observability, code repos, and pipelines Manage access control and permissions. [docs.aws.amazon.com] , [aws.amazon.com] Topology-Driven Investigations Agent continually maps resources and their interdependencies to build the context it needs for effective troubleshooting. [dev.to] , [aws.amazon.com] Correlative Analysis When an alert is triggered, Agent conducts parallel hypothesis-driven analysis: Correlates recent deployment activities, logs/metrics, and resource health Surfaces probable root causes and recommends targeted differential actions. [techstartups.com] , [infoq.com] 🛠️ Integrating GitHub: A Setup Example Account-level authorization required via OAuth to grant AWS DevOps Agent access to repositories. [docs.aws.amazon.com] Once linked, the agent monitors deployment events from specific repositories across Agent Spaces. [docs.aws.amazon.com] 📚 Hands-On Examples & Resources Terraform example : The aws-samples/sample-aws-devops-agent-terraform repo shows how to provision Agent Spaces and IAM roles via Infrastructure as Code. [github.com] EKS Workshop : The sample-devops-agent-eks-workshop repository includes demos (e.g., CloudWatch alerts, EKS failures) that illustrate real-world investigation flows. [github.com] 🎯 When to Use It Situation Benefit You have fragmented observability tools and deployment pipelines AWS DevOps Agent centralizes incident detection, response, and mitigation across tools You want to reduce MTTR and manual on-call fatigue The agent autonomously begins investigations and offers prescriptive fixes You’re aiming to improve long-term system resilience It continuously analyzes past incidents to recommend observability, infra, and pipeline enhancements ✅ Getting Started Enable the preview in us-east-1. Configure an Agent Space and integrate your observability, CI/CD, and chat/ticketing tools. Wire up code repositories via the GitHub integration . Optionally use the Terraform sample to deploy and manage the agent environment. Trigger a test incident (e.g., from CloudWatch/EKS) to validate automatic triage, root-cause detection, and suggested remediation. AWS DevOps Agent is an AI-powered, autonomous incident response and prevention tool that bridges operational silos, significantly reducing human overhead during outages and improving service reliability over time.

Report Abuse Vincent Cavanna Posted on Jan 6 Here's what I'm doing to learn Design Patterns # gangof4 # designpatterns # programming # beginners Design Patterns are everywhere. Or so my boss tells me. While you can go overboard with them, they do wonders in simplifying the steaming hot pile of crap that I wrote a year ago. So this is me writing about how I am going to learn design patterns. To start, I want to use the Gang of 4 book, Design Patterns: Elements of Reusable Object-Oriented Software ( Amazon link here, not an affiliated link). This book is widely considered one of the essential books on design for Object Oriented Programming. Just ask Martin Fowler, author and international speaker on software development: In my view the Gang of Four is the best book ever written on object-oriented design - possibly of any style of design. This book has been enormously influential on the software industry. On the same page he also mentions that it's not an easy book to read, but "unlike most books, however, it amply pays that investment. So what is my approach? After doing a very simple skim of this book, I like one of the approaches suggested by the authors, which is to follow a problem-focused approach rather than a pattern approach... more on that later. Follow along if you like! I'll be writing examples in C++ to help me improve my understanding of the language. Just know that this is me struggling to understand a new language.

Report Abuse Meena Nukala Posted on Jan 10 DevOps Explained: From Buzzword to Real-World Practice 🚀 # devops # cloudnative # tutorial # ai DevOps is one of the most talked-about concepts in modern software development—but also one of the most misunderstood. Is it a role? A toolchain? A culture? The short answer: DevOps is a mindset supported by practices and tools that help teams deliver software faster, safer, and more reliably. In this article, we’ll break down what DevOps really is, why it matters, and how teams actually use it in the real world. What Is DevOps? DevOps is a combination of Development (Dev) and Operations (Ops). Its goal is to eliminate silos between teams responsible for writing code and those responsible for running it in production. Instead of throwing code “over the wall,” DevOps promotes: Collaboration Automation Continuous feedback Shared responsibility At its core, DevOps answers one question: How can we deliver value to users faster without sacrificing stability? Why DevOps Matters Before DevOps, releases were often: Infrequent Risky Manual Stressful DevOps changes this by enabling: 🚀 Faster Delivery Automated pipelines allow teams to deploy multiple times a day instead of once every few months. 🔒 Improved Reliability Infrastructure as code, monitoring, and testing reduce human error. 🤝 Better Collaboration Developers and operations teams work toward shared goals instead of blaming each other. 📈 Scalability Cloud-native infrastructure allows systems to scale automatically with demand. Core DevOps Practices DevOps isn’t about tools first—it’s about practices. Continuous Integration (CI) Every code change is automatically: Built Tested Validated This helps catch bugs early. Popular tools: GitHub Actions, GitLab CI, Jenkins Continuous Delivery / Deployment (CD) Code is always in a deployable state. Continuous Delivery: Manual approval before production Continuous Deployment: Fully automated releases Infrastructure as Code (IaC) Servers and infrastructure are defined using code instead of manual setup. Example (Terraform-style) resource "aws_instance" "web" { instance_type = "t2.micro" } Popular tools: Terraform, AWS CloudFormation, Pulumi Monitoring & Observability You can’t fix what you can’t see. DevOps teams monitor: Logs Metrics Traces Alerts Popular tools: Prometheus, Grafana, ELK Stack, Datadog Automation Everywhere If you do something twice—automate it. Automation applies to: Testing Deployments Infrastructure Security checks DevOps Is a Culture, Not a Job Title One common mistake is thinking “We hired a DevOps engineer, so now we do DevOps.” DevOps works best when: Developers understand production Ops teams contribute to automation Everyone owns reliability DevOps succeeds when responsibility is shared, not outsourced. Common DevOps Tools (Quick Overview) Category Tools Version Control Git, GitHub, GitLab CI/CD Jenkins, GitHub Actions Containers Docker Orchestration Kubernetes Cloud AWS, Azure, GCP Monitoring Prometheus, Grafana Tools change—principles don’t. Getting Started with DevOps If you’re new to DevOps, start small: Learn Git and CI pipelines Containerize a simple app with Docker Automate deployments Add basic monitoring Improve incrementally DevOps is a journey, not a checklist. Final Thoughts DevOps isn’t about moving faster at any cost—it’s about moving smarter. By embracing collaboration, automation, and continuous improvement, teams can: Ship better software Reduce downtime Create happier developers and users And that’s what DevOps is really about. 💡 Top comments (0) Subscribe Personal Trusted User Create template Templates let you quickly answer FAQs or store snippets for re-use.

https://pyfound.blogspot.com/2025/12/sovereign-tech-agency-and-psf-security.html | Python Software Foundation News: Sovereign Tech Agency and PSF Security Partnership   News from the Python Software Foundation Tuesday, December 02, 2025 Sovereign Tech Agency and PSF Security Partnership We are thrilled to announce that the Sovereign Tech Agency has committed to a €86,000 investment in work to be performed by the Python Software Foundation to improve the security of CPython and the Python Package Index (PyPI). The Sovereign Tech Agency is a public organization in Germany that focuses on increasing the security and resilience of critical open source software that forms the foundation of modern digital technology. With the Sovereign Tech Fund, they invest globally in open software components that underpin economic competitiveness and the ability to innovate. Improving the security, stability, and reusability of open software components like CPython and PyPI is a win for everyone. This project consists of two components, which we are carrying out in parallel: one focused on CPython and one focused on PyPI. The CPython component, led by PSF Security Developer in Residence Seth Larson , concerns archive-handling vulnerabilities in CPython’s standard library. Following multiple CVEs affecting the tarfile and zipfile modules, systematic fuzz-testing is required to uncover potential regressions or untested cases in extraction filtering. These modules are used by most Python packaging and installation tools, and therefore form a critical part of the software supply chain. The work commissioned through the Sovereign Tech Fund’s investment will develop test cases and seed corpora for these modules, integrate fuzz-testing through the OSS-Fuzz infrastructure, and validate filtering protections against potential bypasses. The PyPI component, led by PSF PyPI Safety and Security Engineer Mike Fiedler with support from Director of Infrastructure Ee Durbin, focuses on PyPI account integrity and recovery. Current recovery procedures rely solely on email and two-factor authentication, creating support burdens and limiting automated verification. The Sovereign Tech Fund’s investment commissions work that introduces a mechanism for associating PyPI accounts with verified third-party identities through OAuth 2.0 / OIDC flows, allowing account recovery through trusted external services. These associations will improve both user experience and platform reliability while preserving user privacy and autonomy. We appreciate the Sovereign Tech Fund for supporting these critical improvements that will make CPython and PyPI more secure for millions of users. If you’d like to learn more about the advances our Developers in Residence are driving or investing in these roles and work, check out our Developers in Residence page and reach out out to sponsors@python.org Posted by Loren Crary at 12/02/2025 07:00:00 AM Older Post Home Mission The mission of the Python Software Foundation is to promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers.

Privacy Policy Terms of Service Cookies Policy Domain Name System Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN." | 2026-01-13T08:49:05 |
