Async / await explained in 5 seconds

Hi,

import scala.async.Async.{async, await}


  val fiveSeccond = async {
    val start = new java.util.Date()
    
    await { future { Thread.sleep(5000) } }
    
    val t = new java.util.Date()
    s"> ${start.getSeconds} - ${t.getSeconds}"
  }                                               //> fiveSeccond  :  = scala.concurrent.impl.Promise$DefaultPromise@1cb237

BlackBox office power manager command-line script

Hi,

I asked student to make command line interface to the http://www.black-box.at/en-at/fi/1574/12791/Power-Switch-Cabinet-NG/O2.

Device has ajax over http with digest auth interface.

I works just fine, but ...

Random testing on IP addresses is really horrible idea. Half of our platform was down this morning.

Property based testing for unit testers with PropEr – Part 1 «

Property based testing for unit testers with PropEr – Part 1 «: "Eric states his basic expectations as follows:

I can put arbitrary terms into the dictionary as keys
I can put arbitrary terms into the dictionary as values
When I put a value in the dictionary by a key, I can retrieve that same value
When I put a different value in the dictionary by key it does not change other key value pairs.
When I update a value the new value in available by the new key
When a value does not exist a not found exception is created"
