• From Ekiga to Twinkle

    I’ve been using Ekiga (formerly Gnomemeeting) for several years. Among free software phones it was exceptionally stable and well usable since about its 1.0 version. But it supported only the H.323 protocol which became a big problem during the time. H.323 is usually not supported by VoIP providers, it is poorly supported by the Asterisk […]

Now, when recycling fee was introduced several months ago, some of the shops present prices in an even more confusing way. Recently I was going to buy a […]
