  Go Lacks Ternary Operators. Here Are Some Equivalents

If you were like me, a pure Java developer before writing Go, you must be wondering why Go doesn’t support the ternary operator like return a > 1 ? 0 : 1. Most mainstream languages like C and Java are supportive of ternary operators; languages like Python and Ruby support the simplified if-else one-liner, such as a = 0 if a > 1. However, Go is not among them. And it is not only about adding operators but also a concept of coding in a more convenient way, such as the ?: expression can...

  Learn How to Write iOS Apps

My friend contacted me on twitter and asked for advice on different sources on how to learn iOS apps. Since this paragraph will already exceed 140 characters, I'm posting here, instead. (Obviously, reading this blog regularly is a great way to pick up some iOS development tricks) To get started, some people buy a book or find some good online tutorials. I tried both approaches, and the online tutorials were definitely better. I found Stanford's class on iPhone Development, available for free...

  Basic Patterns for Everyday Programming

For most of you the patterns mentioned below should be nothing new. These are very basic stuff we slap into our code everyday and at times feels they are actually code smells than smart patterns. However, I've been doing some code reviewing lately and came across many code that lacks even these basic traits. So I thought of writing them down as a help for novice developers who would want to get a better grasp at these.These patterns are commonly applicable in most general purpose programming lan...

  Run code with multiple files in the same main package in GoLang

To run a GoLang program, there needs to be a main() function defined. In some cases when developing some demo program which has multiple files and just wanna put them in the same main package and this folder is not in GOPATH, how to run the program? Let's say we have following folder structure where the main() function is defined in main.go. If you just run below command, it would fail to start to run the program and gives some error if some struct is defined in other files and being used. PS D...

  In-depth Exploration of Direct and Indirect Dependency Management in GoLang

The dependency management in Golang is handled using go mod. go mod is the official dependency management tool introduced by the Golang team. It assists developers in managing project dependencies to ensure the stability and maintainability of the project code. In go mod, dependencies are categorized into two types based on how packages are imported in the code: direct dependencies and indirect dependencies. Direct dependencies are explicitly referenced in the project code, while indirect depend...

  Bug caused by using changeable value as the default in "python method overload"​

In python we can set the passed in parameter's default value to make the function has the same running feature as the method overload in Java. Define a function like this: def testFunction(self, param1, param2=None, param3=None): Normally we use "None" as the parameter's default value. We can also use str/bool as the default value, but is it OK we use empty list [] as its default value? This is our test program: """ A test program using empty list as the passed-in parameter's default value. ...

  How NOT to teach a computer language

For the past year or so my wife has been taking online classes to get a computer science degree. For most of her classes she’s done great, she’s been flying through HTML and SQL, even up to the point where she can handle multilevel joins and optimizing through indexes. That was until she hit her vb.net class. I had no idea why she was having problems with a language has easy as vb.net so I started helping her out and find out why she was having so many problems. I’ve also ad...

  PHP Sucks! But I Like It!

I read a rather interesting post yesterday called PHP: a fractal of bad design. It's been getting a lot of traffic among the PHP community lately because it's rather inflammatory. But to be honest, it does make a lot of really good points. It also makes a lot of mistakes and misses a bigger picture. A Few Mistakes The post makes quite a few mistakes and odd apples to oranges comparisons. Let me point out the major ones that I saw. No Debugger - PHP has xdebug which works quite...

  Readability in Programming Languages

I saw a side by side comparison of a bunch of scripting languages online recently. Scripting Languages: PHP, Perl, Python, Ruby My first, and second reaction was yuck! Now I have my biases – biases which may  not be shared by others of course. But I like readable code and for me anytime I see a special character (anything not an alphanumeric) it slows me down. This got me thinking about where we are going in design of programming languages? Are we moving forward (what ever ...
