This post is written in English, because I read one article recently that says English is one of the key (programming) languages you need to master. I cannot agree more, :). English is very important for progammers, especially if you want to be a top programmer in specific area. There are much more great resources in English than in other languages, so why not start to write some posts or articles in English and make yourself comfortable with reading, writing and thinking? I appologize for any readers of this blog who do not master English well, but I have to do it for me and for you, because anyhow we need improve ourselves up to the next level and it’s almost impossible without English. Get used to it and you’ll be happy with it soon.
