    Arduino IDE

    Arduino IDE

    Arduino IDE library

    This repository contains the source code of the Arduino IDE 2.x, which is currently in the beta stage. The Arduino IDE 2.x is a major rewrite, sharing no code with the IDE 1.x. It is based on the Theia IDE framework and built with Electron. The backend operations such as compilation and uploading are offloaded to an arduino-cli instance running in daemon mode. This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade. If you need assistance, see the Help Center and browse the forum. If you think you found a vulnerability or other security-related bug in this project, please read our security policy and report the bug to our Security Team. The builds are generated every day at 03:00 GMT from the main branch and should be considered unstable.

    Node-RED

    Node-RED

    Low-code programming for event-driven applications

    Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click. Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the runtime in a single-click. JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use. The light-weight runtime is built on Node.js, taking full advantage of its event-driven, non-blocking model. This makes it ideal to run at the edge of the network on low-cost hardware such as the Raspberry Pi as well as in the cloud.

    Haraka

    Haraka

    A fast, highly extensible, and event driven SMTP server

    Haraka is a highly scalable node.js email server with a modular plugin architecture. Haraka can serve thousands of concurrent connections and deliver thousands of messages per second. Haraka and plugins are written in asynchronous JS and are very fast. Haraka has very good spam protection (see plugins) and works well as a filtering MTA. It also works well as a MSA running on port 587 with auth and dkim_sign plugins enabled. Haraka makes no attempt to be a mail store (like Exchange or Postfix/Exim/Qmail), a LDA, nor an IMAP server (like Dovecot or Courier). Haraka is typically used with such systems. Haraka has a scalable outbound mail delivery engine built in. Mail marked as relaying (such as via an auth plugin) is automatically queued for outbound delivery. Haraka's plugin architecture provides an easily extensible MTA that complements traditional MTAs that excel at managing mail stores but do not have sufficient filtering.

    MailSlurper

    MailSlurper

    Local, web-based mail server application. Slurp mails into oblivion!

    MailSlurper is a small SMTP mail server that slurps mail into oblivion! MailSlurper is perfect for individual developers or small teams writing mail-enabled applications that wish to test email functionality without the risk or hassle of installing and configuring a full-blown email server. It's simple to use! Simply set up MailSlurper, configure your code and/or application server to send mail through the address where MailSlurper is running, and start sending emails! MailSlurper will capture those emails into a database for you to view at your leisure. The following are general instructions for compiling MailSlurper. Your details may vary a bit here and there. The below example is based on a Unix-style system, such as Ubuntu or OSX. Furthermore, for instructional purposes, it is assumed that your GOPATH is set to ~/code/go, and that you have a folder in your source directory called github.com. Your setup may vary.

    MobX

    MobX

    A Simple, scalable state management

    MobX is a battle tested library that makes state management simple and scalable by transparently applying functional reactive programming (TFRP). Write minimalistic, boilerplate free code that captures your intent. Trying to update a record field? Use the good old JavaScript assignment. Updating data in an asynchronous process? No special tools are required, the reactivity system will detect all your changes and propagate them out to where they are being used. All changes to and uses of your data are tracked at runtime, building a dependency tree that captures all relations between state and output. This guarantees that computations depending on your state, like React components, run only when strictly needed. There is no need to manually optimize components with error-prone and sub-optimal techniques like memoization and selectors.

    Image to ico Easymode

    Image to software icon or favicon made simple

    This program makes it simple to get a proper .ico image for your PC software or website favicons. It focuses on what matters and tells you exactly what you need. You feed it an image (png, jpg, gif), it will crop it if its not a square, then it will resize and convert it to the correct format. I have support for these: - Windows PC Exe Programs - 16×16, 32×32, 48×48, 256×256 .ico bundled - Website Favicon - 32x32 .ico - Android Phone Apps - 192x192 .png - Progressive Web Apps (PWA) - 512x512 .png I recommend uploading images atleast 512x512px tall/wide, unless you're doing pixel perfect icons and just want an easier 'convert to .ico format' tool. (Source code is included as it is a standalone offline html file that works in any modern web browser.)

    Ino-L

    Simple programming language for Windows.

    Ino-L is a TUI programming language for Windows that compiles into MS-DOS batch files. Ino-L stands for Innova Language, because Innova is French for innovation. The purpose of the language is to allow programmers the same functionality and abilities of batch files, but with simpler syntax and limited GUI, along with other things MS-DOS does not natively support. Your MS-DOS code can also be incorporated into the Ino-L source code, along with JavaScript and VisualBasic.
