For the 4th consecutive year, the conference on free software and hardware will be held TuxCon. Personally for me this is the strongest Plovdiv conference that is being held, as it is not only aimed at developers, and the target group is much larger and the audience is very colorful. If my memory serves me right, I don't think so, that I have missed an edition so far. This annual edition is especially for me, since I have a presentation. I will talk about dnsdist and whether it is useful for your infrastructure. I chose the topic I will talk about myself. I felt the need to show it to the world, as she is relatively young, and so far I have hardly found anything in it that I do not like. I don't remember the last time I was so impressed by something new and working extremely well at the same time.
