As stated above Functions are smaller procedures that contain small pieces of code which may be repetitive inside a Procedure. Functions are used to reduce redundancy in code. Similar to a Procedure, A function can be declared with or without an arguments list. Function is declared as a return ty...

In Sprite-Kit, there is the concept of collisions which refers to the SK physics engine handling how physics objects interact when they collide i.e. which ones bounce off which other ones. It also has the concept of contacts, which is the mechanism by which your program gets informed when 2 physics...

y ~ . : Here . is interpreted as all variables except y in the data frame used in fitting the model. It is equivalent to the linear combinations of predictor variables. For example y ~ var1 + var2 + var3+...+var15 y ~ . ^ 2 will give all linear (main effects) and second order interaction terms of t...

There is a way to simplify defining autolayout for views using VFL. It may seem hard at first, but it is actually really easy to use. Some definitions first: | represents superview H: or V: represent current orientation - horizontal or vertical view names should be enclosed in square brackets ...

Checkpointing configuration is done in two steps. First, you need to choose a backend. Then, you can specify the interval and mode of the checkpoints in a per-application basis. Backends Available backends Where the checkpoints are stored depends on the configured backend: MemoryStateBackend...

The code Here is a simple flink application using a stateful mapper with an Integer managed state. You can play with the checkpointEnable, checkpointInterval and checkpointMode variables to see their effect: public class CheckpointExample { private static Logger LOG = LoggerFactory.getLogge...

A savepoint stores two things: (a) the positions of all datasources, (b) the states of operators. Savepoints are useful in many circonstances: slight application code updates Flink update changes in parallelism ... As of version 1.3 (also valid for earlier version): checkpoint must be ...

Configuration The configuration is in the file flink/conf/flink-conf.yaml (under Mac OSX via homebrew, it is /usr/local/Cellar/apache-flink/1.1.3/libexec/conf/flink-conf.yaml). Flink < 1.2: The configuration is very similar to the checkpoints configuration (topic available). The only differenc...

Before 1.2, the only way to persist state/retain a checkpoint after a job termination/cancellation/persistant failure was through a savepoint, which is triggered manually. Version 1.2 introduced persistent checkpoints. Persistent checkpoints behave very much like regular periodic checkpoints except...
