vtracer

Homepage/demo Docs Source code

VTracer is an open source software to convert raster images (like jpg & png) into vector graphics (svg). It can vectorize graphics and photographs and trace the curves to output compact vector files.

Comparing to Potrace which only accept binarized inputs (Black & White pixmap), VTracer has an image processing pipeline which can handle colored high resolution scans. tl;dr: Potrace uses a O(n^2) fitting algorithm, whereas vtracer is entirely O(n).

Comparing to Adobe Illustrator's Image Trace, VTracer's output is much more compact (less shapes) as we adopt a stacking strategy and avoid producing shapes with holes.

VTracer is originally designed for processing high resolution scans of historic blueprints up to gigapixels. At the same time, VTracer can also handle low resolution pixel art, simulating image-rendering: pixelated for retro game artworks.


Event Notify Test Runner

A utility for running arbitrary commands when files change. Uses kqueue(2) or inotify(7) to avoid polling. entr was written to facilitate rapid feedback on the command line.

Source code

Project page

ENTR uses STDIN, so you can pipe into it as part of your shell workflow.

Rebuild a project if source files change, limiting output to the first 20 lines:

find src/ | entr -s 'make | head -n 20'

Launch and auto-reload a node.js server:

ls *.js | entr -r node app.js

Clear the screen and run a query after the SQL script is updated:

echo my.sql | entr -cp psql -f /_

Rebuild project if a source file is modified or added to the src/ directory:

while sleep 0.1; do ls src/*.rb | entr -d make; done

Auto-reload a web server, or terminate if the server exits

ls * | entr -rz ./httpd


MoltenGamepad

Flexible input device remapper, geared towards gamepads

Source Code

The goal is to make any controller "just work", even as they are inserted or removed from the system. For complicated input devices, this can even involve writing specialized support to fully exploit their features.

MoltenGamepad targets a set-it-and-forget-it daemon-like usage pattern, where devices can connect or disconnect freely. Its main purpose is letting a user "standardize" their software to expect just one type of controller, and then automagically transform connected input devices to match that standardized abstraction.

CD-R 700mb

Modern static site generator for making web mixtapes.

source code project page

Before Spotify, Apple Music, Amazon Music Unlimited, Amazon Music HD, Google Play Music, Tidal, Deezer, Pandora, Idagio, LiveXLive, Primephonic, SiriusXM Essential, SiriusXM Premier, and YouTube Music, we listened to mixtapes. We compiled tracks on iTunes and burned them onto CD-Rs. We traded them with each other. We freely listened in our car or at home or with our portable CD player. And it was good.

Today we might spend an eternity making the perfect playlist for someone special, only to learn they're on the Z Music Unlimited service while you're on X Music Basic. Now, vendor lock-in means love lock-out. Our connections are disconnected. Our romantic hopes aren't high enough for the surrounding paywalls. What can we do?

This is a static site generator for "burning" a modern mixtape. It's platform-independent and won't get scratched up in your car.

Run this program inside a directory of music files to produce a bare-bones HTML page that will simply play the music for someone. Upload it all to your website, and share the URL. Boom, you have a mixtape.

This only takes care of "burning the CD," if you will -- then it's up to you to make it special, like you would a normal mixtape. Add track notes, make it look cool or funky, do something that takes a little more effort than sharing a freaking Spotify playlist. All this tech convenience has made us lazy and boring. So make something interesting! Show someone that they mean something to you!


faircamp

source code project page

Point Faircamp to a folder hierarchy on your disk which contains your audio files. Within minutes, Faircamp builds a complete, static website that presents your music to your audience. You can view the site on your computer or upload it to any webhost - no database, no php or such required.

By default, visitors can browse and stream your music. You can enable more features: Downloads, Embeds, Soft Paycurtain, Unlock codes for Downloads, RSS Feed, etc.. You can also provide text descriptions for your releases, adjust the theme of your site and so on, this is all done in manifests, simple text files you place next to your audio files.

If your webspace supports SSH access, faircamp can be configured to upload your website for you automatically, otherwise you can use FTP or whichever means you prefer to do that manually.

syncplay

Solution to synchronize video playback across multiple instances of mpv, VLC, MPC-HC, MPC-BE and mplayer2 over the Internet.

source code project page

Pausing, unpausing and seeking are synchronized over the Internet, giving everyone playing the same file in the same virtual room a shared viewing experience. Use alongside VoIP software, e.g. Mumble or Skype.

Syncplay synchronises the position and play state of multiple media players so that the viewers can watch the same thing at the same time. This means that when one person pauses/unpauses playback or seeks (jumps position) within their media player then this will be replicated across all media players connected to the same server and in the same 'room' (viewing session). When a new person joins they will also be synchronised. Syncplay also includes text-based chat so you can discuss a video as you watch it (or you could use third-party Voice over IP software to talk over a video).

alpakka

The Alpakka controller is Input Labs' main reference design, a re-interpretation of the standard gamepad that everyone is familiar with, but with advanced gyro controls, mouse-like competitive performance, and the power of an open source community bringing limitless accessibility and customization options.

Having the performance of a mouse combined with the convenience of a gamepad, you won't have to make any compromise anymore.

Source Code

Homepage

Zero software

"Gaming peripherals and bloatware apps, name a more iconic duo"

No drivers, no apps, no overlays, no bloat. The Alpakka firmware emulates as a standard keyboard, mouse, and Xinput gamepad at hardware level; so it just works out of the box in Windows and Linux, and every game launcher.

Instead of having per-game configurations, the firmware includes 8 profiles carefully crafted for different game genres, that can be switched directly on the controller (for example: FPS, racing, flight).

With 2 gyro sensors working in parallel, and the hexagonal touch-sensitive surface surrounding the ABXY buttons, we finally cracked the code for gyro as primary input.

Gyro controls are not an afterthought anymore, they are the new default. And since a secondary thumbstick would be redundant, instead it features a scrollwheel and a 8-directional "physical selection wheel".

Chatter Net Client

Chatter Net is a modern decentralized semantic web built atop self-sovereign identity.

Source Code Homepage. For more, you can have a look at the sibling server project, and a prototype work-in-progress social application used to dog food the development process.

Chatter Net is a platform which is:

Chatter Net does not rely on a specific network stack or protocol. It is instead specified by its data model. It would be possible (though prohibitively slow) to operate a Chatter Net network using carrier pigeons.

Whereas the world wide web is a web of HTML documents, Chatter Net is a web of self-signed semantic documents. It closely follows (but is not fully compliant with) the Activity Pub protocol. Consequently, it is closely related to other federated platforms, of which Mastodon is the a well established platform.

Chatter Net's self-signed data model does differ in a subtle yet meaningful way: the authority resides in the users of the network, not the servers.

This is what allows the project to realize its objectives.

No de-platforming: since no server is needed to verify the identity of a user, no server can prevent a user from accessing the network. No platform lock-in: since no server is needed to verify the authenticity of data, no server can lock data away from users and other servers. No spam from arbitrary users: would-be spammers need not only convince a server to trust them, they must directly convince other users.

Diamond Types

The world's fastest CRDT. WIP.

Source Code

Blog post on making diamond types 5000x faster than competing CRDT implementations And since that blog post came out, performance has increased another 10-80x (!).

As well as being lightning fast, this library is also designed to be interoperable with positional updates. This allows simple peers to interact with the data structure via operational transform.

This repository contains a high performance rust CRDT for text editing. This is a special data type which supports concurrent editing of lists or strings (text documents) by multiple users in a P2P network without needing a centralized server.

This version of diamond types only supports plain text editing. Work is underway to add support for other JSON-style data types. See the more_types branch for details.


Boondock Echo

Homepage

Radio reception in mountainous terrain is sporadic. During an emergency, poor communication can cost lives. The proposed solution is internet-backed time-shift radio.

This project uses commercial off-the-shelf handheld radios and a microcontroller-based internet gateway to receive and store messages on a server where they can be queued for playback locally or through a remote repeater. This solution allows increased communication in mountainous terrain with limited capital expenditure. Radio operators can capture traffic during a pileup, monitor multiple frequencies of interest, and replay important messages.


Nomad Network - Communicate Freely

Off-grid, resilient mesh communication with strong encryption, forward secrecy and extreme privacy.

Nomad Network Allows you to build private and resilient communications platforms that are in complete control and ownership of the people that use them. No signups, no agreements, no handover of any data, no permissions and gatekeepers.

Nomad Network is build on LXMF and Reticulum, which together provides the cryptographic mesh functionality and peer-to-peer message routing that Nomad Network relies on. This foundation also makes it possible to use the program over a very wide variety of communication mediums, from packet radio to fiber optics.

Nomad Network does not need any connections to the public internet to work. In fact, it doesn't even need an IP or Ethernet network. You can use it entirely over packet radio, LoRa or even serial lines. But if you wish, you can bridge islanded networks over the Internet or private ethernet networks, or you can build networks running completely over the Internet. The choice is yours.

Notable Features - Encrypted messaging over packet-radio, LoRa, WiFi or anything else Reticulum supports. - Zero-configuration, minimal-infrastructure mesh communication - Distributed and encrypted message store holds messages for offline users - Connectable nodes that can host pages and files - Node-side generated pages with PHP, Python, bash or others - Built-in text-based browser for interacting with contents on nodes - An easy to use and bandwidth efficient markup language for writing pages - Page caching in browser


Lightweight Extensible Message Format

LXMF is a simple and flexible messaging format and delivery protocol that allows a wide variety of implementations, while using as little bandwidth as possible. It is built on top of Reticulum and offers zero-conf message routing, end-to-end encryption and Forward Secrecy by default.

Source code

LXM Propagation Nodes offer a way to store and forward messages to users or endpoints that are not directly reachable at the time of message emission. Propagation Nodes can also provide infrastructure for distributed bulletin, news or discussion boards.

When Propagation Nodes exist on a Reticulum network, they will by default peer with each other and synchronise messages, automatically creating an encrypted, distributed message store. Users and other endpoints can retrieve messages destined for them from any available Propagation Nodes on the network.


reticulum

Self-configuring, encrypted and resilient mesh for LoRa, packet radio, WiFi and everything in between

Source Code

Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. It can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption and connectivity, initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable delivery acknowledgements and more.

The vision of Reticulum is to allow anyone to be their own network operator, and to make it cheap and easy to cover vast areas with a myriad of independent, inter-connectable and autonomous networks. Reticulum is not one network. It is a tool for building thousands of networks. Networks without kill-switches, surveillance, censorship and control. Networks that can freely interoperate, associate and disassociate with each other, and require no central oversight. Networks for human beings. Networks for the people.

The full documentation for Reticulum is available at markqvist.github.io/Reticulum/manual/.

You can also download the Reticulum manual as a PDF

For more info, see unsigned.io/projects/reticulum

Notable Features - Coordination-less globally unique addressing and identification - Fully self-configuring multi-hop routing - Initiator anonymity, communicate without revealing your identity - Asymmetric X25519 encryption and Ed25519 signatures as a basis for all communication - Forward Secrecy with ephemeral Elliptic Curve Diffie-Hellman keys on Curve25519 - Reticulum uses the Fernet specification for on-the-wire / over-the-air encryption - Keys are ephemeral and derived from an ECDH key exchange on Curve25519 - AES-128 in CBC mode with PKCS7 padding - HMAC using SHA256 for authentication - IVs are generated through os.urandom() - Unforgeable packet delivery confirmations - A variety of supported interface types - An intuitive and easy-to-use API - Reliable and efficient transfer of arbitrary amounts of data - Reticulum can handle a few bytes of data or files of many gigabytes - Sequencing, transfer coordination and checksumming are automatic - The API is very easy to use, and provides transfer progress - Lightweight, flexible and expandable Request/Response mechanism - Efficient link establishment - Total bandwidth cost of setting up an encrypted link is 3 packets totaling 297 bytes - Low cost of keeping links open at only 0.44 bits per second

Where can Reticulum be used? Over practically any medium that can support at least a half-duplex channel with 500 bits per second throughput, and an MTU of 500 bytes. Data radios, modems, LoRa radios, serial lines, AX.25 TNCs, amateur radio digital modes, WiFi and Ethernet devices, free-space optical links, and similar systems are all examples of the types of physical devices Reticulum can use.

An open-source LoRa-based interface called RNode has been designed specifically for use with Reticulum. It is possible to build yourself, or it can be purchased as a complete transceiver that just needs a USB connection to the host.

System-wide colorscheming and typography for NixOS

Stylix is a NixOS module which applies the same color scheme, font and wallpaper to a wide range of applications and desktop environments. In some cases, theming can be activated as early as the bootloader! It also exports utilities for you to apply the theming to custom parts of your configuration. Stylix is built using base16.nix, a library which handles the generation of config files from templates provided by the base16 project. If you only set a wallpaper, Stylix will use a homemade genetic algorithm to choose a color scheme based on it. The quality of the generated palettes can vary - but more colorful images tend to have better results.

You can force a light or dark theme using the polarity option: stylix.polarity = "dark";

You can override part of the scheme by hand, perhaps to select your background and text colors manually while keeping the genetic accent colors.
