Filmow

"O Filmow foi criado para pessoas viciadas e apaixonadas por filmes. A principal ideia do Filmow é que você mostre aos seus amigos os filmes que já assistiu, comente sobre eles e dê sua opinião, na página do filme. Mas, para os que apenas gostam de filmes, o Filmow também é uma rede social onde é possível encontrar pessoas e amigos. No Filmow você fica sabendo quais filmes são lançados, os que estão no cinema e aqueles que já estão em DVD, para você assistir em casa." (http://filmow.com/sobre-o-filmow/)

Your Product Owner Is Not Your Product Manager

Your Product Owner Is Not Your Product Manager. Product management has evolved to encompass numerous roles and responsibilities. Leaders looking to hire a product professional must consider what skills and knowledge their business needs demand.

While the market has evolved and will continue to evolve, there remains a need for both a product owner’s and a product manager’s skills and expertise. By considering the nature and scale of a project and understanding the skills and responsibilities associated with each of these distinct roles, leaders can ensure they hire the right person to help them develop and launch products successfully.

How Much maintenance_work_mem Do I Need?

While I generally like PostgreSQL's documentation quite a bit, there are some areas where it is not nearly specific enough for users to understand what they need to do. The documentation for maintenance_work_mem is one of those places. It says, and I quote, "Larger settings might improve performance for vacuuming and for restoring database dumps," but that isn't really very much help, because if it might improve performance, it also might not improve performance, and you might like to know which is the case before deciding to raise the value, so that you don't waste memory. TL;DR: Try maintenance_work_mem = 1GB. Read on for more specific advice.

HTTP-over-QUIC will officially become HTTP/3

The protocol that's been called HTTP-over-QUIC for quite some time has now changed name and will officially become HTTP/3. This was triggered by this original suggestion by Mark Nottingham.

The QUIC Working Group in the IETF works on creating the QUIC transport protocol. QUIC is a TCP replacement done over UDP. Originally, QUIC was started as an effort by Google and then more of a "HTTP/2-encrypted-over-UDP" protocol.
