Libevent – an event notification library

The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. Furthermore, libevent also support callbacks due to signals or regular timeouts.

libevent is meant to replace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop.

Rwx-calc is a small utility for calculating file and directory permissions as found on Unix/Linux like system, including the Jolla.

You can provide the absolute octal values, but also press on the individual permission to see the effect on the fly.

The help screen will provide some additional info on the permissions if needed.

This is a simple viewer for PassBook® files.

The app searches the file system, starting in the home directory, for passes, and shows them in a list. A tap on the pass shows the details including the barcode (usually the most important thing). The design is simplified compared to the original app, but should be readable.

some packages to re-enable ssl handshake in older SFOS versions, i.e. if you're stuck on SFOS1.0.0.5 after factory reset (glibc 2.19 should be installed before)

This is HexTool for Sailfish.

HexTool is a simple calculator for hex, bin, oct and dec.

All values are editable so you can put a new hexdecimal value, decimal value, change single bits, put an ip address or ASCII chars. It will automatically calculate other fields for you.

PetitTrack is a satellite tracker. PetitTrack is based on the keplerian propagator algorithm used in kd2bd's Predict software. At this stage v1.3.0 the algorithm from 2002.

PetitTrack is a software tool for determining the position of earth satellite orbits in relation to an earth observer.

Before you use the software:

Experimental audio manipulation app for SF. Cut audio files or recordings and apply effects like fade-in, emphasize, echo or denoiser.

As of SF 3.3 there is no mp3-encoder included in the OS yet. If you need to save as mp3, you have to install LAME encoder as well. It is available in chum. Using lame, however, requires starting the app from a terminal. wav, ogg and flac export should (tm) just work.

E-book reader for Sailfish OS.

The core functionality is based on FBReader source code with a few modifications. In theory, it should be able to handle all E-book formats supported by FBReader. Books are imported from the ~/Downloads folder, where they are saved by the browser or email client. Alternatively, you can manually copy your books to the ~/Documents/Books directory. Removable storage (SD-card) is supported as well. Switch between SD-card and internal memory by flicking left and right. Use volume keys, swipe or touch to turn the pages.

The idea of the game is to make words by selecting letters. The game is at it's best when having multiple players on the same LAN network.
