CalDAVTester is a test and performance application designed to work with CalDAV and / or CardDAV servers and tests various aspects of their protocol handling as well as performance.

CalDAVTester basically executes HTTP requests against a server and verifies the responses returned by the server. Suites of tests are defined in xml configuration files, and an additional xml configuration file is used to define variables used whilst running (e.g., server address, user accounts to use etc).

A test suite configuration file comprises the following items:

A start section where resources needed for the tests can be created
A set of test suites, comprising:
    A set of tests, each of which can have:
        A set of HTTP request/response/verify tests.
An end section to do clean-up after the tests are all done.

The source code to CalDAVTester is available via GIT.

The linux-based open-source mobile operating system Android is not only the most popular mobile operating system in the world, it’s also on the way to becoming a proprietary operating system. How is that?

While the core operating system is still released as part of the Android Open Source Project, the majority of core apps are not. It gets worse: More and more libraries and APIs are only available on phones that run various Google apps pre-installed, effectively locking third-party apps to the Google ecosystem. For these reasons Android is described as being a “look but don’t touch” kind of open.

At this point, several popular open-source applications like the secure messenger Signal already require some of Google’s proprietary libraries to be installed. Increasing demand in the free software community in addition to severe problems in Google’s proprietary software discovered by the Android modding community, have led to the development of a free software clone of Google’s proprietary core libraries and applications - the microG Project was born.

Although most microG components are far from complete, users are amazed by the results. Free software users got extended application support, privacy-caring users can reduce or monitor data that is sent to Google and especially older phones can expect some battery life improvements. microG is not only used on real devices, but also replaces Google tools in test emulators and is even used in virtual mobile infrastructure.

Anchor is an ephemeral PKI service that, based on certain conditions, automates the verification of CSRs and signs certificates for clients. The validity period can be set in the config file with hour resolution.

OwnTracks allows you to keep track of your own location. You can build your private location diary or share it with your family and friends. OwnTracks is open-source and uses open protocols for communication so you can be sure your data stays secure and private.

Straightforward DNS hosting services

Being one of leading DNS hosting providers, we always strive to provide the best possible feature set to our users. With the help of our users, we continue to improve the feature set and functionality of YDNS by adding useful features. This community driven approach makes YDNS special.

The feature set currently includes:

Unlimited hosts1 per user
Dynamic DNS for hosts, which can be used to have your home network on a permanent hostname (like example.ydns.io)
Full DNS hosting for your own domains
Backup DNS
DNSSEC2 support
A lightweight API that works with most DynDNS implementations

1 based on fair-use model, 2 DNSSEC is not available for all DNS zones

This is pump.io. It's a stream server that does most of what people really want from a social network.

WOPR is a simple markup language for creating rich terminal reports, presentations and infographics.

Put a report on the web (e.g. gist) and view it via curl:

$> curl -N tty.zone/\[0-2\]\?auto\&cols=$((COLUMNS))

(If you experience firewall issues replace tty.zone with ec2-23-21-64-152.compute-1.amazonaws.com or use a local viewer)

phpipam is an open-source web IP address management application. Its goal is to provide light and simple IP address management application.

to be able to display javascript quickly and correctly.

Features and tools:

• Section / Subnet separation
• Subnet nesting
• IPv4/IPv6 support
• REST API
• Subnet ICMP/telnet scanning and automatic status updates
• Displays free range and number of clients
• Subnet statistics
• User management
• AD/LDAP/OpenLDAP/Radius authentication support (multiple servers)
• E-Mail notification with IP details
• Import IP addresses from XLS / CSV file
• Export IP database to XLS file
• IPv4/IPv6 calculator

• and much more...

What it does not do:

• Updates DNS server

The Radicale Project is a complete CalDAV (calendar) and CardDAV (contact) server solution.

Calendars and address books are available for both local and remote access, possibly limited through authentication policies. They can be viewed and edited by calendar and contact clients on mobile phones or computers.

Radicale aims to be a light solution, easy to use, easy to install, easy to configure. As a consequence, it requires few software dependencies and is pre-configured to work out-of-the-box.

Radicale runs on most of the UNIX-like platforms (Linux, *BSD, MacOS X) and Windows. It is free and open-source software, written in Python, released under GPL version 3.

Welcome on the wiki page of the only add-on for Thunderbird and Seamonkey which will add access to you Exchange calendars, contacts and Global Address List [GAL]. It is an add-on for the Lightning. Calendering Add-on and will allow you to communicate with an Exchange 2007, 2010 and 2013 server using the Exchange Web Service [EWS] interface.You can access any Calendar, Task or Contacts folder on the EWS server in an easy way. And also manage your [Out of Office] settings.

etcd is a distributed, consistent key value store for shared configuration and service discovery with a focus on being:

Simple: curl'able user facing API (HTTP+JSON)
Secure: optional SSL client cert authentication
Fast: benchmarked 1000s of writes/s per instance
Reliable: properly distributed using Raft

etcd is written in Go and uses the Raft consensus algorithm to manage a highly-available replicated log.

See etcdctl for a simple command line client. Or feel free to just use curl, as in the examples below.

If you're considering etcd for production use, please see: production-ready.md

No netsplits on server unavailability

Traditional IRC networks split whenever a server has brief network connectivity issues to the rest of the IRC network, or whenever a server needs to be upgraded. With RobustIRC, your users will not notice when you roll out a new version or reboot the machine on which a particular RobustIRC server is running.

Robust against connectivity issues between clients and the network

A brief hickup of your internet connection means your session will be terminated in traditional IRC. With RobustIRC, you will transparently be connected to a different server.

Keybase is a website, but it's also an open source command line program. Let's walk through a terminal example, which illustrates what Keybase does. All of this can be embedded into other software, written by anyone.

The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. Stunnel uses the OpenSSL library for cryptography, so it supports whatever cryptographic algorithms are compiled into the library.
