    Acrylic DNS Proxy

    A local DNS proxy which improves the performance of your computer

    Acrylic is a local DNS proxy for Windows which improves the performance of your computer by caching the responses coming from your DNS servers and helps you fight unwanted ads through the use of a custom HOSTS file (optimized for handling hundreds of thousands of domain names) with support for wildcards and regular expressions. When you browse a web page a portion of the loading time is dedicated to name resolution while the rest is dedicated to the transfer of the web page contents. What Acrylic does is to reduce the time dedicated to name resolution for frequently visited addresses closest to zero possible. Furthermore Acrylic's sliding expiration caching mechanism and DNS silent updates are able to improve the browsing experience independently of the browser. With Acrylic you can also gracefully overcome downtimes of your DNS servers without disrupting your work, because in that case you will at least be able to connect to your favourite websites and to your email server.

    WiFiManager

    WiFiManager

    WiFi Connection manager with web captive portal

    Espressif ESPx WiFi Connection manager with fallback web configuration portal. The configuration portal is of the captive variety, so on various devices it will present the configuration dialogue as soon as you connect to the created access point. When your ESP starts up, it sets it up in Station mode and tries to connect to a previously saved Access Point. If this is unsuccessful (or no previous network saved) it moves the ESP into Access Point mode and spins up a DNS and WebServer (default ip 192.168.4.1). Using any wifi enabled device with a browser (computer, phone, tablet) connect to the newly created Access Point. Because of the Captive Portal and the DNS server you will either get a 'Join to network' type of popup or get any domain you try to access redirected to the configuration portal. ESP will try to connect. If successful, it relinquishes control back to your app. If not, reconnect to AP and reconfigure.

    PeerGuardian

    PeerGuardian - a privacy oriented firewall application

    PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology. Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. Collaboration with peerblock.com is welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).

    TCNOpen

    TCNOpen

    Components for IEC61375 standardised communication

    TCNOpen is an open source initiative which the partner railway industries created with the aim to build in collaboration some key parts of new or upcoming railway standards, commonly known under the name TCN. TCN (Train Communication Network) is a series of international standards (IEC61375) developed by Working Group 43 of the IEC (International Electrotechnical Commission), specifying a communication system for the data communication within and between vehicles of a train. It is currently in use on many thousands of trains in the world in order to allow electronic devices to exchange information while operating aboard the same train. TCNOpen follows the Open Source scheme, as the software is jointly developed by participating companies, according to their role, so as to achieve cheaper, quicker and better quality results.
