I often hear the interest rates yielded this result of massive inflation or massive recession. But I'm not sure I believe that. I'm not convinced that the 0% interest rates lead to the massive inflation. So a non-mainstream econom

That is wrong. Every description of rollback mentinos that. Replaying inputs after rolling back can result in a new state that is different from the client predictino which amounts to teleporting.

On more thought I don't see how what you're saying is relevant to my point. The server needs to maintain the current state (which is based on the latest input it has received). No matter how you do the networking rollback or not y

Ok interesting there is a lag compensation feature. I did not think of the server having something like that precisely because of what you mentioned it sounds like this is something the players can use to abuse or cheat with.

So consider a first person shooter with no rollback you're probably going to be aiming slightly ahead of the person to compensate for latency lag. And maybe you'll aim to the other side of the person if you think they changed dire

Question why is rollback networking good for games? To play devil's advocate with the lag hidden wouldn't this lead me to make decisions without considering the possibility that the opponent has already made a decision that is opp

I don't think that is correct. I don't think the market actually needs phd level stats skills. Its just like the market doesn't need phd level pure math or doesn't need phd level CS. The number of situations where these

So another way of saying this is consider the space of languages where * control over memory use and layout (in contrast java is a pig over memory usage) * some kind of easy way to use multicore (goroutines with channels or something else)

So for anyone reading this and seeing other comments about gain of function. The first thing you should realize is that the people here commenting about gain of function have no idea what they are talking about. They are completely clueless

To be a contrarian here to bring up a question, do these things really count? The roots of similar ideas already existed decades ago in old journals for all of these. Maybe the phrase "System Software Research is Irrelevant" could

Are there open source news aggregators?

Do any of them have details of how they built their news aggregator? For example, what infrastructure did they use to crawl, parse, and index the pages, etc.

In my mind the big advantage of Go over Node that is sometimes overlooked is that your code in Go is written in a largely serial manner with no callbacks. With Go you don't have to deal with a lot of callbacks when doing I/O since goroutin

Are any of these good for RTS games? Or is the overhead too much compared to a modified A* path finder that only finds close to optimal paths?

If I am understanding correctly the suggestion is to have a distributed hash table that any backend can lookup to find the other backend it should forward to. And since the distributed hash table is critically important persistent data I'm

So in practical terms how does one setup backends to use WebSockets. For example, suppose you have nginx in front of a bunch of Unicorn or Rainbow processes and there are two clients that have made websocket connections. Consider a chat app

Are WebSocket connections persistent to a single backend? That is, suppose Nginx is in front of two Unicorn processes. Will Nginx maintain a mapping table of client browser connection to Unicorn process, so that messages will always hit the

Can someone explain, to people who know nothing about scaling infrastructure, why routing to idle dynos is a hard problem?

That's not a privacy issue. That's a I don't want feature X (ads) issue.

jquery and bootstrap are great for putting together a rails app really quick, but I wish there was a better way that didn't add bloat. I find that jquery and bootstrap add significant download latency to a webpage even if they are gzipped.
