@Duga Why was that approved? I'd say it's an attempt to reply and should be posted as comment or part of an answer.
Second opinion anyone?
On a completely unrelated note: I suspect we need to rewrite the LCC close reason to prevent it from being abused as UWYA. I think we can do this, might write a meta on it later.

@tmptplayer I suggest you to ask a new question with examples or a code review on codereview.stackexchange.com as it is unclear to me what you exactly think is more beneficial then this method. Seems like you have to create a property for each translation key and implement that in each implementation of the interface. How can this be more maintainable then an exportable option like Resx Manager provides? — CularBytes 26 secs ago

So you should focus on the actual questions. 1) Is whatever you’re doing there involving multiple threads and requiring synchronization on your side? (That’s obviously a question regarding the redis API) 2) Is whatever you are doing sufficient to provide the necessary synchronization? (That’s obviously a code review question). If not → fix it. It’s irrelevant whether or how the problem materializes. Even if it happens to do the intended thing now for a while, the problem will materialize some day. Neither of these two questions are about the HashMap implementation. — Holger 27 secs ago

Journalists have an uneasy relationship with technology. On one hand, journalism at the highest levels still focuses on print distribution, a technology hundreds of years old. On the other hand, even the Gray Lady has a snazzy mobile app and  stories custom made for virtual reality. Traditional news outlets are increasingly discovering the power of interactive journalism. To do that right, you need a team of people working on a story—a journalist, a data scientist, a programmer, and a UX designer. It’s rare that you get all four skills in a single person. …
