Cloud Torrent
Cloud Torrent, a self-hosted remote torrent client
Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect. -

Proton Mail Bridge
Proton Mail Bridge application
Proton Mail Bridge is a desktop application that runs in the background on Windows, macOS, and Linux to enable users to access their Proton Mail encrypted email accounts with traditional email clients like Outlook, Thunderbird, Apple Mail, and others via local IMAP/SMTP servers. Because standard IMAP cannot natively decrypt end-to-end encrypted messages, Bridge acts as a translator that downloads encrypted mail, decrypts it locally, and serves it to your preferred mail client over a local server, while encrypting outgoing messages before they’re sent to Proton’s servers. It provides a seamless integration layer for users who need offline support, familiar local client workflows, or tighter integration with desktop tools while preserving Proton’s zero-access encryption model. The Bridge app continues running even when its GUI is closed so that mail clients can remain connected and synchronized, and it supports automatic startup and robust credential handling via secure storage. -

IPFS Kubo
An IPFS implementation in Go
Kubo was the first IPFS implementation and is the most widely used one today. Implementing the Interplanetary Filesystem - the Web3 standard for content-addressing, interoperable with HTTP. Thus powered by IPLD's data models and the libp2p for network communication. Kubo is written in Go. IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas from previous systems such as Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single BitTorrent swarm, exchanging git objects. IPFS provides an interface as simple as the HTTP web, but with permanence built-in. You can also mount the world at /ipfs. -

qrcp
Transfer files over wifi from your computer to your mobile device
qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete. When used to receive files, qrcp serves an upload page and handles the transfer. Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser. When sending multiple files at once, qrcp creates a zip archive of the files or folders you want to transfer, and deletes the zip archive once the transfer is complete. When receiving files, qrcp serves an “upload page” through which you can choose files from your mobile. The default configuration file is stored in $HOME/qrcp.json, however, you can specify the location of the config file by passing the --config flag. -

Lens
Lens is an opt-in search engine and data collection tool
Lens is an opt-in search engine and data collection tool to aid content discovery of the distributed web. It exposes a simple, minimal API for intelligently indexing and querying content on IPFS. Initially integrated with Temporal, Lens will allow users to optionally have the data they upload be searched and indexed and be awarded with RTC for participating in the data collection process. Users can then search for content using a simple-to-use API. Searching through Lens will be facilitated through Temporal web. Optionally, we will have a service independent from Temporal which users can submit content to have it be indexed. This however, is not compensated with RTC. In order to receive the RTC, you must participate through Lens indexing within the Temporal web interface. -

Notify
A dead simple Go library for sending notifications to message services
A dead simple Go library for sending notifications to various messaging services. Notify was born out of my own need to have my API servers running in production be able to notify me when critical errors occur. Of course, Notify can be used for any other purpose as well. The library is kept as simple as possible for quick integration and ease of use. Since Notify is highly dependent on the consistency of the supported external services and the corresponding latest client libraries, we cannot guarantee its reliability nor its consistency, and therefore you should probably not use or rely on Notify in critical scenarios. -
