For the 4th consecutive year, will take place the Conference on free software and hardware TuxCon. Personally for me it is the most strong Plovdiv Conference which is held, Since it is targeted for developers only, and the target group is much bigger and the audience is very colorful. If memory serves me correctly I don't think, I missed Edition so far. This year's Edition is more special to me, Since I have a presentation. I'm going to talk about dnsdist and as to whether it is useful for your infrastructure. The theme of which will speak it chose Sam. I felt the need to show it to the world, as it is a relatively young, and so far I've barely found something in it that I don't like. I don't remember when was the last time he impressed me so much something new and at the same time works extremely well.
