Using getopts to process long and short command line options
...or using the bash builtin getopts to mimic long options. That solution actually makes a short option whose character is "-". So you get "--" as the flag. Then anything following that becomes OPTARG, and you test the OPTARG with a nested case.
This is clever, but it comes with caveats:
getopts ca...
How to get Vim to highlight non-ascii characters?
...aracter range, therefore highlighting (assuming you have hlsearch enabled) all other characters lying outside the ASCII range:
/[^\x00-\x7F]
This will do a negative match (via [^]) for characters between ASCII 0x00 and ASCII 0x7F (0-127), and appears to work in my simple test. For extended ASCII,...
Why don't Java Generics support primitive types?
...nerics in Java are an entirely compile-time construct - the compiler turns all generic uses into casts to the right type. This is to maintain backwards compatibility with previous JVM runtimes.
This:
List<ClassA> list = new ArrayList<ClassA>();
list.add(new ClassA());
ClassA a = list.g...
Why XML-Serializable class need a parameterless constructor
...me to accept that public parameterless constructors are great because they allow you to use "new()" with generics and the new initialization syntax. For parametered constructors use static factory methods or the builder pattern implementation.

Fragment or Support Fragment?

From my experience, using the same fragment implementation on all Android devices is a great advantage. I could not get rid of all NullPointerExceptions when state is saved on Android 4.0 using native fragments, with the support library they are all gone. Also I could not see any disadv...
Execute command on all files in a directory
...rovide the code to do the following:
Assume there is a directory of files, all of which need to be run through a program. The program outputs the results to standard out. I need a script that will go into a directory, execute the command on each file, and concat the output into one big output file.

What is the difference between int, Int16, Int32 and Int64?
...al, on modern computers, an int16 takes as much space as an int32 (and actually an int64) because in order for most operations to be efficient, we pad around the data to make accesses aligned to 32 or 64 bit boundaries (in 32 or 64 bit modes respectively). This is because unaligned accesses are ridi...
