 Hello again, my name is Vladimir. I think all of you use something to optimize your files for your projects. Is it so? One, just one, two, three, okay. Well, we like to have our projects fast, so we optimize them very hard and we realized that there are a bunch of tools to make your project working fast, but still we wanted to make it even better and we created a lot of tools. All of them are written in Node.js and open sourced and the first of them is CSSO, that stands for CSS Optimizer. It does all the things that you all used to when working with CSS Optimizer, it removes spaces and all that stuff, but it differs from the other because inside of it, there is CSS parser and that's why we can optimize CSS in a very special way. We can apply structural optimizations and so, and it's very smart and I think it's the only CSS Optimizer with such great results. Then we started to support Ritina displays, so we need some SVG in our projects and that's why we came up with SVG. That means SVG Optimizer, I don't understand, and it's in still in development, but even right now it results in very great optimized SVG files and again, it's written in Node.js and open sourced. Also, we have such a tool as сеточка, it's a Russian word and what it does is to parse your CSS file and take out just some parts of it according to some special rules. For example, you can write CSS for all the browsers in one file, then ask сеточka to find everything that corresponds just to Internet Explorer and get it into a separate file and include it separately just for that browser. Again, as I already mentioned, we have that CSS parser and it's open sourced too. It's called Kanzales. Finally, we have a tool and it's the only one which isn't on Node.js, it's Img.o, Optimizer for Images. Actually, it's just a bash script, but what it does is it tries to optimize your image with a lot of different optimizers and try to find the best just for your particular image. That's why the compression is the best. Of course, you can participate and help us to improve these tools and ask us the questions. All of them are presented on bm.info slash tools. Thanks.
