Reading numbers from standard input is a combination of reading strings and parsing such strings as numbers. The parse function is used to parse a string into the desired number type: julia> parse(Int, "17") 17 julia> parse(Float32, "-3e6") -3.0f6 The format expec...

Reading strings or bytes Files can be opened for reading using the open function, which is often used together with do block syntax: open("myfile") do f for (i, line) in enumerate(eachline(f)) print("Line $i: $line") end end Suppose myfile exists and its ...

Java Logging Api has 7 levels. The levels in descending order are: SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value) The default level is INFO (but this depends on the system and used a virtual machine). Note: There are also levels OFF (can be used to turn log...

Elastic Beanstalk (EB) is essentially a hybrid between Golden AMIs and CloudFormation, while vastly simplifying the learning curve of Puppet or Chef. An Elastic Beanstalk deployment is broken down into two components: Application and Environment. Application Consider this your top-level groupin...

Blue/Green deployment is a release technique that reduces downtime and risk by running two identical production environments (one called "Blue", the other called "Green"). At any one time, only one of the environments is serving live traffic, while the other is sitting idle. Whe...

Powershell supports standard conditional logic operators, much like many programming languages. These allow certain functions or commands to be run under particular circumstances. With an if the commands inside the brackets ({}) are only executed if the conditions inside the if(()) are met $test =...

Templates require compile-time generation of code: a templated function, for example, will be effectively turned into multiple distinct functions once a templated function is parameterized by use in source code. This means that template function, member function, and class definitions cannot be del...

Overview The transpose function is one of Bosun's more powerful functions, but it also takes effort to understand. It is powerful because it lets us alert at different levels than the tag structure of the underlying data. Transpose changes the scope of your alert. This lets you scope things into l...
