Sonda do světa otevřeného softwaru. Dnes si vyzkoušíme moderní hudební přehrávač, zmenšíme si SVG soubory, vytvoříme si seznam sledovaných filmů a seriálů a nakonec si přehrajeme hudbu z příkazového řádku.

Tauon

Velmi moderní a uživatelsky velmi přívětivý hudební přehrávač pro stolní počítače, který funguje v systémech Windows i Linux. Dokáže přehrávat různé typy místních zvukových souborů, včetně MP3, FLAC a OGG.

Umí také importovat skladby Spotify a dokonce ovládat přehrávání Spotify, stejně jako přehrávat hudbu ze serverů Keol a Airsonic. Kromě toho nabízí možnost přehrávání bez mezer, podporu textů včetně synchronizovaných souborů IRC a kytarových akordů.

Oh My SVG

Aplikace pro Linux, která vám pomůže zmenšit velikost souborů SVG. Jako hlavní engine používá SVGO, nástroj založený na Node.js, určený pro optimalizaci vektorových grafických souborů.

Nejen, že umí měnit velikost SVG souborů, ale umí taky odstranit spoustou nadbytečných informací, které mohou některé SVG obsahovat jako jsou komentáře, skryté prvky, výchozí a neoptimální hodnoty.

Ticket Booth

Aplikace, která umožňuje vytvářet seznam sledovaných filmů a televizních seriálů, vyhledávat příslušné informace a také sledovat vybrané tituly. Kromě toho můžete také vylepšovat informace z databáze webu a také se účastnit diskusí o filmech a seriálech.

Díky svému grafickému rozhraní GTK/Libadwaita je ideální pro uživatele prostředí GNOME. Využívá rozhraní TMDb API, což je otevřená alternativa k filmové databázi IMDB.

Kew

Aplikace pro přehrávání hudby z příkazového řádku. Je kompletně napsaná v jazyce C, je malá (nepřesahuje 1 MiB), s nízkou náročností na paměť. Můžete si v ní i vytvářet a přehrávat vlastní seznamy skladeb a nabízí i vyhledávání v adresářích s hudbou. Ovládá se pomocí klávesových zkratek.

Blbinka

Přijde vám sympatické rozhodnutí EU o standardizaci nabíjecích konektorů, ale zároveň se nechcete vzdát svého starého telefonu. Kde je vůle, tam je cesta.
