Raspberry Pi Car Computer Part 1: Initial Setup and basic parts

Raspberry Pi LogoSo many times in movies and TV shows we have seen computers in cars that had so many fantastic features. From KITT in Knight Rider up to James Bond movies we have seen some great computers in cars and it was getting us all excited to what will come in the future. So here in 2016, computers are still a luxury in cars and still don’t offer everything that we dreamed of, given the technology we have.

Jesus vs Satan: Who is the better programmer?

hqdefaultJesus and Satan have an argument as to who is the better programmer.  This goes on for a few hours until they come to an agreement to hold a contest with God as the judge.  They set themselves before their computers and begin.  They type furiously, lines of code streaming up the screen, for several hours straight.

As useful as a COBOL programmer

cobolThere was once a COBOL programmer in the mid to late 1990s. For the sake of this story, we’ll call him Jack. After years of being taken for granted and treated as a technological dinosaur by all the UNIX programmers and Client/Server programmers and website developers, Jack was finally getting some respect. He’d become a private consultant specializing in Year 2000 conversions. He was working short-term assignments for prestige companies, traveling all over the world on different assignments, and making more money than he’d ever dreamed of.

Out vs Ref in C#

csharpAll languages, or at least most, have some way of passing a value by reference. When we wish to return more than one values from a method or simply if we want to use the classic value swap paradigm then we need to pass values by reference to our method. C has pointers (which in fact you are still passing the pointer to your method by value, but in fact that pointer has a reference to the variable you want to change) Visual basic has the ByRef argument and many other languages have their own way of doing this.

Checking for nulls? Not anymore

nullA huge pain in the arse for most developers is the need to null check everything before starting to use it. Microsoft has introduced null operators in previous versions of C# and upgraded them in C# 6.0 but still, we can and we should avoid them.

How? Well by avoiding nulls altogether.
Can we do that? Of course we can.

Let’s see how

Pitfalls of Lasagna Code

SpaghettiCodeWe all know what spaghetti code is. For those of you that do not here is a small description by Wikipedia.

Spaghetti code is a pejorative phrase for source code that has a complex and tangled control structure, especially one using many GOTO statements, exceptions, threads, or other “unstructured” branching constructs. It is named such because program flow is conceptually like a bowl of spaghetti, i.e. twisted and tangled. Spaghetti code can be caused by several factors, such as continuous modifications by several people over a long life cycle. Structured programming greatly decreases the incidence of spaghetti code.

That’s cool and all but what the hell is Lasagna code? Continue reading Pitfalls of Lasagna Code

Usefulness of Yoda expressions in programming

yodaIn programming jargon, Yoda conditions (also called Yoda notation) is a programming style where the two parts of an expression are reversed from the typical order in a conditional statement. A yoda condition places the constant portion of the expression on the left side of the conditional statement. The name for this programming style is derived from the Star Wars character named Yoda, who spoke English in a non-standard syntax.

Java Sucks, and here’s why

Java-logoJava is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2015, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems’ Java platform.
