3r3-31. We all know from the school course what the number system (SS) is. But not everyone thinks about how costly SS. Those. what set of numbers we need to represent the number in this CC.

(all red pebbles are zero, green - one, blue - two, etc., small - zero discharge, medium - first, large - second, etc.).

Why technical skills project manager: explain on cases

Not everyone will be able to effectively lead a team of IT specialists. The work of a project manager in IT is distinguished by the fact that in it system analytical skills are closely related to technical skills. They are necessary for the project manager and are not limited to in-depth knowledge in one or two areas. The success of PM in IT also largely determines the understanding of the digital market as a whole, knowledge of what is under the hood of technological systems, how and why they are designed, how they work.

After half a year, I decided to use the trial budget for acquaintance with dataproc, the pre-installed Hadup cluster from Google. The task is to try to estimate how easy it would be for me to start a project on Google’s Hadup, is there any sense in it or is it better to ...

Why am I not using story points to plan a

sprint.Hi, Habr! I present to you the translation of Article “Why I Don’t Use Story Points for Sprint Planning” by Mike Cohn. 3r375. 3r375. As described in Agile Estimating and Planning, I’m a big fan of story points to evaluate the backlog of a product. However, I also recommend evaluating the backlog of the sprint in hours, and not in story points. Why is this apparent contradiction? I previously wrote about the reasons. I recommend using different units of measurement (points and hours) for different backlog. 3r375.3r3365. 3r375. But I am often asked a related question that I want to ask here: 3r375. 3r375. ...
