PHPMailer
The classic email sending library for PHP
PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe! -

IRremote Arduino Library
Infrared remote library for Arduino, send and receive infrared signals
This library enables you to send and receive using infra-red signals on an Arduino. You can use any pin for sending now like you are used to receiving. Simultaneous sending and receiving. See the SendAndReceive example. No more need to use 32-bit hex values in your code. Instead, a (8 bit) command value is provided for decoding (as well as a 16-bit address and a protocol number). Protocol values comply to protocol standards, i.e. NEC, Panasonic, Sony, Samsung, and JVC decode and send LSB first. Supports more protocols, since adding a protocol is quite easy now. Better documentation and more examples. Compatible with tone() library, see ReceiveDemo. Supports more platforms, since the new structure allows to easily add a new platform. Feedback LED also for sending. Ability to generate a non-PWM signal to just simulate an active low receiver signal for direct connection to existent receiving devices without using IR. -

Official Android SDK for Stream Chat
Android Chat SDK ➜ Stream Chat API. UI component libraries for chat
This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components and fall back to the lower-level API when they want to customize things. We're proud to say that we're the first Android Chat SDK that supports Jetpack Compose! We released our Compose UI Components one day after the official Jetpack Compose 1.0 release and our team members have been working hard on it since then. Now it's mature and stable enough for us to officially recommend it for all new applications and all modern chat implementations. If you're looking for something highly customizable and extremely performant, check out our Compose SDK. -

base64 RFC1113 Vanilla ANSI-C Code for a portable stand-alone file encode/decode utility. In 2001, I asked people to 'Help me break it!' Since then, 10+years later, the code remains unbroken and is in wide production use world-wide. It has been ported to all major architectures and been used as a template for ports to different computer and human languages. This is very mature and stable code. Although this comes from a project that was constrained by export controls and is used in secure systems, it is not security code per-se. I have therefore altered the 'Export Controls' category.

TrackersListCollection
A list of popular BitTorrent Trackers
TrackersListCollection is a daily-updated collection of BitTorrent tracker server lists, curated and filtered from across the internet to build a “best of” list and a full list for usage in torrent clients, automation, or performance tuning. The project scans public trackers, tests their responsiveness or status, categorises them (e.g., all trackers vs best trackers), and makes plain-text files available (like best.txt, all.txt) that can be included in download clients or scripts. Because trackers can go offline or degrade over time, the daily refresh schedule is crucial for maintaining a high-quality list. The repo also includes metadata and mirrors to handle international usage and multiple download sources. For people who use torrent infrastructure, ensure peers connect reliably, or want to automate external tracker lists for aria2 or other clients, this is a practical and well-maintained source. -

Rasa
Open source machine learning framework to automate text conversations
Rasa is an open source machine learning framework to automate text-and voice-based conversations. With Rasa, you can build contextual assistants on Facebook Messenger, Slack, Google Hangouts, Webex Teams, Microsoft Bot Framework, Rocket.Chat, Mattermost, Telegram, and Twilio or on your own custom conversational channels. Rasa helps you build contextual assistants capable of having layered conversations with lots of back-and-forths. In order for a human to have a meaningful exchange with a contextual assistant, the assistant needs to be able to use context to build on things that were previously discussed. Rasa enables you to build assistants that can do this in a scalable way. Rasa uses Poetry for packaging and dependency management. If you want to build it from the source, you have to install Poetry first. By default, Poetry will try to use the currently activated Python version to create the virtual environment for the current project automatically. -

Google's common Java, C++ and JavaScript library for parsing, formatting, and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich). libphonenumber gets the type of the number based on the number itself; able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP, Personal Numbers, UAN, Pager, and Voicemail (whenever feasible). Provides valid example numbers for all countries/regions, with the option of specifying which type of example phone number is needed. Quickly guesses whether a number is a possible phone number by using only the length information, much faster than a full validation. To include the Java code in your application, either integrate with Maven (see wiki) or download the latest jars from the Maven repository. -

tmi.js
Javascript library for the Twitch Messaging Interface
Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false. -

Eris
A NodeJS Discord library
A Node.js wrapper for interfacing with Discord. You will need NodeJS 10.4+. If you need voice support you will also need Python 2.7 and a C++ compiler. Create a directory for your bot, and change to that directory in your command line. If you want to be more updated (at the expense of stability), you can install the beta builds instead. Eris supports a few optional libraries that could potentially improve bot performance but may require additional dependencies. If you want Eris to use any of these packages, install them in the same directory as Eris, and Eris will automatically use them. You can find more examples on the GitHub repo. The rest of the docs will help you with using the various functions of the library. Have fun! -
