Before we get our hands dirty with code, I feel it is necessary to understand how data is stored in firebase. Unlike relational databases, firebase stores data in JSON format. Think of each row in a relational database as a JSON object (which is basically unordered key-value pair). So the column nam...

I am gonna assume you already know about adding gradle dependencies firebase in android studio. If you don't just follow the guide from here.

A LocalDate is a date without a timezone. Consider using them when you are only concerned with the year, month, and day of month and are not interested in an exact time. For example, when we write our date of birth (such as 1960-01-01) we don't care about the timezone in which it happened.

The following lines of code is more smart way to setting up the base_url in codeigniter: $config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http"); $config['base_url'] .= "://".$_SERVER['HTTP_HOST']; $config[...

This is a sample HTTP client based on Ev extension. Ev extension implements a simple yet powerful general purpose event loop. It doesn't provide network-specific watchers, but its I/O watcher can be used for asynchronous processing of sockets. The following code shows how HTTP requests can be sche...

Donald Knuth is often quoted as saying this: "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered....

TEST CASE – A test case is a set of conditions and steps that when followed/applied, a tester can determine whether a feature, an application or a software system is working as originally designed. A test case usually contains References to the original task, Pre-conditions ( if the pre-conditions...

In order to achieve type safety sometimes we want to avoid the use of primitive types on our domain. For instance, imagine a Person with a name. Typically, we would encode the name as a String. However, it would not be hard to mix a String representing a Person's name with a String representing an e...

This is just an extension on the sealed trait variant where a macro generates a set with all instances at compile time. This nicely omits the drawback that a developer can add a value to the enumeration but forget to add it to the allElements set. This variant especially becomes handy for large en...
