As a developer I think Netflix done great job about bandersnatch. They have designed a complex story map, where the story flows and the user who watches the movie can choose the direction of the flow. Definitely there will be many critics about this decision of the Netflix. Because many people will think that movie is the art which must created by artist and watched only with a single flow. What Netflix has done with bandersnatch is new type off art called interactive movie, but it sounds more like a description to the technology. Could be given more fancy specific name.

We will need a UserDetailService implementation, which depends on each development requirements.

Today I’m starting the series of Spring-Security articles, and most of them will be references from web-sites and book named “Spring-Security” from authors Mick Knutson,Robert Winch and Peter Mularien. Before going into an example of Spring Security lets clarify why do we need spring security.

The book has been written by Sam Newman, who talks about microservice architecture usage around the world, including in organizations like Netflix, Amazon, Gilt and the REA group, who have all found that the increased autonomy gives huge advantages to their teams. While I was reading this book, I got the similar feelings to the books such as “Clean Code” and “Clean Architecture”. The author has collected many useful experiences about microservice architecture, some of them very familiar to us, but some of them are gives us “aha” points.

The book was what I have expected from infrastructure book. There were no source codes, except some configuration scripts. The book contains the collection of experiences about cloud-native solutions. It mostly talks about development and deployment processes on the cloud-native.

Korean Open Source Software Conference has gathered many open source communities and contributors. It has become common for conferences these days have tracks: AI, BigDATA, Blockchain, Cloud. This conference was no exception. I have visited cloud development related topics.

Conference organized by NHN Enterprise (Intercontinental Seoul Parnas 19.11.2018) has encompassed many different topics. I have especially was interested in java related topics. How the big tech companies like NHN itself would approach the issue regarding to Oracle recent declarations about Java becoming non-free anymore.

P and NP is the problem that always comes out while we are studying algorithms, and usually, it comes up at the end of any algorithms book. The reason it comes out at the latest pages is that it is quite an advanced topic.

The book has been written by Cal Newport, a professor at the Georgetown University (Washington D.C). He wrote about the importance of the focusing and concentration on the work, by increasing the limit of the time we usually allocate for it. The Author writes a lot of different use cases for great historical people (some of them are still alive), how they have been going deep into their work. Who used what kind of technique, and how the technique was mastered. While going through the book I have realized that all of these characters had some similar points and patterns. Concentration Technique !!!

Problem

Given a graph which represents a flow network where every edge has a capacity. Also given two vertices source S and sink T in the graph. Find out the maximum possible flow from S to T with following constraints
