    Planet

    Planet

    Build and host decentralized blogs and websites on your Mac

    Planet is a free and open source tool for publishing and following web content. It doesn't rely on a central server or service, and instead uses IPFS for peer-to-peer content distribution. You can also link your content to an Ethereum Name (e.g. yourname.eth) so that others can follow you on Planet using your .eth name. Since both IPFS and ENS are decentralized, you can use Planet to build and follow websites in a decentralized way. Did you know that you can use an Ethereum Name (ENS) to set up a website? It's true! You can use the Content Hash field, just like you would use an A or CNAME record for a traditional domain name. The standard for this is EIP-1577, and the Content Hash field can accept a few different values.

    Polly

    Polly

    A .NET resilience and transient-fault-handling library for policies

    Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+. Today's cloud application, mobile, data-streaming, and IoT technologies all depend vitally on reliable connectivity. But underlying systems can fail, and networks are notoriously fickle, outages, latency, transient blips, spikes in load, all challenge 100% reliability. Polly helps you navigate the unreliable network. By providing resilience strategies in fluent-to-express policies such as Retry, WaitAndRetry, and CircuitBreaker, Polly can help you reduce fragility, and keep your systems and customers connected. Example usages are fault-tolerance for any distributed systems and inter-process calls, such as WCF, RESTful calls between microservices, calls to cloud services, Internet of Things connectivity, etc.

    Ribbon

    Ribbon

    Ribbon is an inter process communication library

    Ribbon is a Inter Process Communication (remote procedure calls) library with built in software load balancers. The primary usage model involves REST calls with various serialization scheme support. Ribbon comprises of multiple components some of which are used in production internally and some of which were replaced by non-OSS solutions over time. This is because Netflix started moving into a more componentized architecture for RPC with a focus on single-responsibility modules. So each Ribbon component gets a different level of attention at this moment. APIs that integrate load balancing, fault tolerance, caching/batching on top of other ribbon modules and Hystrix. Load balancer APIs that can be used independently or with other modules. APIs using Eureka client to provide dynamic server list for cloud.

    ShowDoc

    ShowDoc

    ShowDoc is a tool greatly applicable for an IT team to share documents

    When we take over a module or project which has been developed by others, we always feel crazy watching at the codes without notes or comments. Programmers often want others to write technical documents, but not by themselves. Writing technical documents need lots of time and works, such as it needs to consider how to handle the format and layout of the documents. Beside, the man who writes the documents has to think all kinds of non-technical details. For example, which catalog should to be put in the newly-established word document. In general, all kinds of word documents are dispersively maintained by different people in a team. ShowDoc is a tool greatly applicable for an IT team to share documents online. It can promote communication efficiency between members of a team. With the development of mobile Internet, BaaS (Backend as a Service) becomes more and more popular.

    Swoosh

    Swoosh

    Compose, deliver and test your emails easily in Elixir

    We have applied the lessons learned from projects like Plug, Ecto and Phoenix in designing clean and composable APIs, with clear separation of concerns between modules. Swoosh comes with many adapters, including SendGrid, Mandrill, Mailgun, Postmark and SMTP. Compose, deliver, and test your emails easily in Elixir. Swoosh supports the most popular transactional email providers out of the box and also has an SMTP adapter. Adding new adapters is super easy and we are definitely looking for contributions on that front. Get in touch if you want to help! Check the documentation of the adapter you want to use for more specific configurations and instructions. Swoosh does not make any special arrangements for sending emails in a non-blocking manner. Opposite to some stacks, sending emails, talking to third party apps, etc in Elixir do not block or interfere with other requests, so you should resort to async emails only when necessary.

    UDEX

    UDEX

    Secure and Decentralized Exchange + Wallet for Ethereum ERC20 tokens

    We believe that private property is untouchable and market access is unconditional. That is why we engineered a crypto exchange that is equally open to all, lives online forever and unconditionally protects your assets. It is fully peer-to-peer and works without any centrally managed servers. It can't be stopped, blocked or taken down. Such an approach enables the wallet to operate anywhere and remain censorship-resistant. Only the user is in control of the money. Wallet-to-wallet token trading is the most secure way to trade ERC20 tokens directly from your Ethereum wallet. Trading cryptocurrencies doesn't have to mean losing custody. Use UDEX to maintain control of your ERC20 tokens while trading directly from your wallet. Trade when you want, where you want, without a middleman.

    go-textile

    Infrastructure for building composable apps and services on the IPFS

    Textile provides encrypted, recoverable, schema-based, and cross-application data storage built on IPFS and libp2p. We like to think of it as a decentralized data wallet with built-in protocols for sharing and recovery, or more simply, an open and programmable iCloud. Textile is still under heavy development and no part of it should be used before a thorough review of the underlying code and an understanding that APIs and protocols may change rapidly. There may be coding mistakes and the underlying protocols may contain design flaws. Please let us know immediately if you have discovered a security vulnerability. Textile is a set of tools and trust-less infrastructure for building censorship-resistant and privacy-preserving applications. While interoperable with the whole IPFS peer-to-peer network, Textile-flavored peers represent an additional layer or sub-network of users, applications, and services.

    Free, open source mental health communication web app

    if-me.org is a community for mental health experiences that encourages people to share their personal stories with trusted allies. Trusted allies are the people we interact with on a daily basis, including friends, family members, co-workers, teachers, and mental health workers. Dealing with mental health is what makes us human. But for a lot of us, it's a struggle to be open about it. Not everyone is a counselor or therapist. The people who we interact with every day shape our emotions and behavior. Getting them involved in mental health treatment is the key to recovery. The live site can be found at if-me.org. The live design systems can be found at design.if-me.org. We use the wonderful Contributor Covenant for our code of conduct. Please read it before joining our project.

    libphonenumber for PHP

    libphonenumber for PHP

    PHP version of Google's phone number handling library

    A PHP library for parsing, formatting, storing and validating international phone numbers. This library is based on Google's libphonenumber. This library will try to follow the same version numbers as Google. There could be additional releases where needed to fix critical issues that can not wait until the next release from Google. This does mean that this project may not follow Semantic Versioning, but instead Google's version policy. As a result, jumps in major versions may not actually contain any backward-incompatible changes. Please read the release notes for such releases. This library uses phone number metadata from Google's libphonenumber. If this library is working as intended, it should provide the same result as the Java version of Google's project. If you believe that a phone number is returning an incorrect result, first test it with libphonenumber via their Online Demo.
