The most restrictive scope is "object-private" scope, which only allows that value to be accessed from the same instance of the object. class FooClass { private[this] val x = "foo" def aFoo(otherFoo: FooClass) = { otherFoo.x // <- This will not compile, accessing x...
The package protected scope allows the value to be accessed only from any subclass in a specific package. package com.example { class FooClass { protected[example] val x = "foo" } class ClassB extends FooClass { val y = x // It's in the protected scope, will compile ...
The following Less: .paragraph{ font-size: 12px; color: blue; background: white; } .parent{ font-size: 14px; color: black; background: green; .nestedParagraph:extend(.paragraph){ } } will compile into the following css: .paragraph, .parent .nestedParagraph { ...

You can establish a transaction by calling the pipeline method on the StrictRedis. Redis commands executed against the transaction are performed in a single block. # defaults to transaction=True tx = r.pipeline() tx.hincrbyfloat(debit_account_key, 'balance', -amount) tx.hincrbyfloat(credit_acc...
In this example the microcontroller echos back the received bytes to the sender using UART RX interrupt. #include "stm32f4xx.h" UART_HandleTypeDef huart2; /* Single byte to store input */ uint8_t byte; void SystemClock_Config(void); /* UART2 Interrupt Service Routine */ void...

By default, NuGet restores packages into the packages folder in the solution root. This folder is shared between all solution projects. In some cases it is useful to change the location of the restored packages (for instance, to share them between several solutions). Its can be achieved by creating...
Add gem 'figaro' to your Gemfile and run bundle install. Then run bundle exec figaro install; this will create config/application.yml and add it to your .gitignore file, preventing it from being added to version control. You can store your keys in application.yml in this format: SECRET_NAME: secre...

Once you have established a connection to Redis you can get and set values using the Jedis connection object: Get String value = jedis.get(myKey); Set jedis.put(myKey, "some value");

Local mode In local mode, for example when running your application from an IDE, you can configure log4j as usual, i.e. by making a log4j.properties available in the classpath. An easy way in maven is to create log4j.properties in the src/main/resources folder. Here is an example: log4j.rootLogger...
In case you need different settings for your various applications, there is (as of Flink 1.2) no easy way to do that. If you use the one-yarn-cluster-per-job mode of flink (i.e. you launch your scripts with: flink run -m yarn-cluster ...), here is a workaround : create a conf directory somewhe...
Yarn does not by default aggregate logs before an application finishes, which can be problematic with streaming jobs that don't even terminate. A workaround is to use rsyslog, which is available on most linux machines. First, allow incoming udp requests by uncommenting the following lines in /etc/...
