Many of us are facing the challenge of promoting the idea of speed of user experience within our organizations and crave any support data to help “sell” it to business stakeholders, product managers and engineers. Real User Measurement (RUM) is a great…

Speed needs to be designed Speed of User Experience (UX) is important for your web sites and mobile applications, but it often takes a back seat to functional improvements and is always thought of as purely technical exercise – proactive at…

I’ve been at truTV, formerly Court TV for 11½ years which by industry standards is pretty long run with any company. Well, I’ve worked with some great people and done quite a few interesting projects in-house and outside, especially in Web Performance space so I consider it a good and productive run. Anyway, doesn’t matter how long something lasts, there will be…

I don’t know why, but my brain is constantly wandering away when I read an interesting book. Sometimes it makes me re-read paragraphs or even whole chapters over again because I completely miss the point while reading automatically with my eyes, but being somewhere else in my thoughts.

If I’m uncomfortable about doing something, if I hear the voice of the…

I’m working on HowDoable for a few months already and it’s been a fun ride and main challenge is to go towards the goal. I’m using Pivotal tracker for my agile needs and i have a long backlog which I’m adding to more stuff over time, rearranging the list and so on. What I noticed…

Steve Souders wrote a post about people mispronouncing his name. Obviously, I’m an emigrant which makes it different, but in my case people usually can’t finish pronouncing my last name and stumble somewhere in the middle ;) I even thought about borrowing a nickname from Ernesto Guevara, so it’s easier to remember like Sergey “Che”…

I’m done with my copy of Even Faster Web Sites. It’s definitely a book worth reading if you’re well into web performance optimization and want to step even further when all simpler optimizations don’t bring any more improvements. JavaScript sections from Ajaxians and Nicholas Zakas are quite interesting but definitely for most complex 2.0 apps…
