I am a newbie game developer and I have been researching about multiplayer games. I observed that there's always some latency, the players always get updates from past actions. But there are techniques like dead reckoning to handle the latency. I can predict the movement and make movements smooth. But how would I make actions synchronize like jumping, stopped walking, etc.

Suppose, client A was moving, he was at 100m at 10.2 time with 100m/sec velocity and sended this information. Client B would receive this information somewhat later, let it be 10.4. So at client B, I can use prediction and place client A at 120m. But what if, client made a jump at 110m at 10.3. I can't predict that and since I have been using prediction I can't show client A jump in past.

I may deal with this problem by not sending jump action at all. But what if my game has some voids where players can fall and die. So, If I don't sync jump actions, other players will observe that one player was running then he falls in void and then again appear on the screen destroying the visual engagement. 

Jump is just an example, there might many scenarios where prediction can't work. So, How do deal with them. One such example can be Multiplayer Online battle arena games like Awesomenauts.


Question: Kosher salt vs. Table salt for rib eye steak
Answer: The difference in salt is more related to how the salt is being used.  So for the purpose of quickly salting before cooking or at the table any type of salt will do.

However if you are salting your meat at least an hour in advance and letting it rest before cooking (which I HIGHLY recommend you do) then using the larger grains of Kosher salt has a positive effect.  Salting the meat causes the proteins contained in the meat to change and allows the meat to retain juices significantly better.  At the same time some of the salt is pulled into the meat as the water that has been drawn out of the meat through osmosis is reabsorbed back into the meat near the end of the hour.  Using a finer grain salt, such as table salt, will allow significantly more salt to be absorbed into the meat.  Using a coarse grain salt, kosher, will mean a more perfectly salted piece of meat.
