The Ozeki VoIP Service Checker is a tool you can use for checking the availability of VoIP services. It can be used to verify whether a given service exists, see whether it can be reached from a particular network, and check whether the user details (such as the username and password) to access the service are correct. It was developed because many mobile Internet providers block VoIP traffic.
Audible TTS reads text aloud from other apps, the clipboard, or from text files. It can get text from applications such as Feedme or K9-Mail, the clipboard (using Copy and Paste), or from files on the MicroSD card. It also reads each sentence using the proper language and voice in mixed texts, without having to select it manually. You must have installed a voice synthesizer (such as PICO or SVOX) and voices for the languages to be used. It currently supports German, English, Spanish, French, Italian, Dutch, Polish, Portuguese, Turkish, Russian, Arabic, Korean, Chinese, and Japanese.
pyscmpd is a music player daemon designed for use on Raspberry Pis. It implements a subset of the MPD protocol, but instead of serving local MP3 files, it connects to SoundCloud.com and serves the streams found there. It supports a huge number of front-end clients through MPD, including ncmpcpp and Sonata. It allows you to configure which parts of SoundCloud are made available for browsing by defining categories and adding groups or users to them.
Shelk-test is a program for creating tests for students. Tests take up just three modules: creation, testing, and reporting. Shelk-test can insert images into all types of questions, making it possible to create a question such as "What is shown in the picture?" All tests are stored centrally in a SQLite database, increasing reliability and allowing you to have a database file without having to install a database server.
