These days, it seems I have gotten accustomed to my work and feel myself to be getting a bit looser than I was at first. Too early for me to be so, then I decided to pay more attention to what had been in progress in development sections and around it.
At the first, I began looking more deeply inside issues, pull-reqs, and commits on GitHub, and reading through all the daily reports of my colleagues. I must get in touch with wide-range of people as far as possible. It takes so long time, but shouldn't result in vain, I guess.
