To comment on the same line as the code you can use &:: or &rem. You can also use && or || to replace &. Example : @echo off echo This is a test &::This is a comment echo This is another test &rem This is another comment pause A curiosity: SET command allows limit...

the easiest way is to have the local branch checked out: git checkout old_branch then rename the local branch, delete the old remote and set the new renamed branch as upstream: git branch -m new_branch git push origin :old_branch git push --set-upstream origin new_branch

DateUtils.formatDateTime() allows you to supply a time, and based on the flags you provide, it creates a localized datetime string. The flags allow you to specify whether to include specific elements (like the weekday). Date date = new Date(); String localizedDate = DateUtils.formatDateTime(contex...

Format a date: Date date = new Date(); DateFormat df = DateFormat.getDateInstance(DateFormat.MEDIUM); String localizedDate = df.format(date) Format a date and time. Date is in short format, time is in long format: Date date = new Date(); DateFormat df = DateFormat.getDateTimeInstance(DateFor...

Date date = new Date(); df = new SimpleDateFormat("HH:mm", Locale.US); String localizedDate = df.format(date) Commonly used patterns: HH: hour (0-23) hh: hour (1-12) a: AM/PM marker mm: minute (0-59) ss: second dd: day in month (1-31) MM: month yyyy: year

These are general tips that in general improve performance. If your code is slow, it is always important to profile it to figure out what parts are slow. Guessing is never enough. Improving the execution speed of something that only takes up 1% of the execution time probably isn't worth the effort. ...

CountDownTimer is useful for repeatedly performing an action in a steady interval for a set duration. In this example, we will update a text view every second for 30 seconds telling how much time is remaining. Then when the timer finishes, we will set the TextView to say "Done." TextView ...

Overriding properties (both read-only and mutable): abstract class Car { abstract val name: String; open var speed: Int = 0; } class BrokenCar(override val name: String) : Car() { override var speed: Int get() = 0 set(value) { throw UnsupportedOpera...

A tsconfig.json file can contain both line and block comments, using the same rules as ECMAScript. //Leading comment { "compilerOptions": { //this is a line comment "module": "commonjs", //eol line comment "target" /*inline bl...

The sample content used here is Tears of Steel, by Blender Foundation. Specifically, we will use the download titled "HD 720p (~365MB, mov, 2.0)". This is a single file that ends with the extension "mov" and will play in just about any modern media player. Note that the download...

Add post-formats to post_type 'page' add_post_type_support( 'page', 'post-formats' ); Next example registers custom post type 'my_custom_post_type', and add Post Formats. Register custom post type 'my_custom_post_type' add_action( 'init', 'create_my_post_type' ); function create_my_post_type(...

Function Call add_theme_support( 'post-formats' )

Here are a simple example of some common tasks related to developing an API, differentiating between the HTTP Method of the request, accessing query string values and accessing the request body. Resources http.Handler interface http.ResponseWriter http.Request Available Method and Status cons...

Atomic types are the building blocks of lock-free data structures and other concurrent types. A memory ordering, representing the strength of the memory barrier, should be specified when accessing/modifying an atomic type. Rust provides 5 memory ordering primitives: Relaxed (the weakest), Acquire (f...

TestNG allows defining groups which can include other groups. MetaGroups logically combine one or more group(s) and control the execution of the @Testmethods belonging to those groups. In below example there are various @Test methods belonging to different group(s). Few are specific to particular s...

Using the Swift class Mirror works if you want to extract name, value and type (Swift 3: type(of: value), Swift 2: value.dynamicType) of properties for an instance of a certain class. If you class inherits from NSObject, you can use the method class_copyPropertyList together with property_getAttrib...

All UI elements created and reside in the main thread of a program. Accessing these from another thread is forbidden by the .net framework runtime. Basically it is because all UI elements are thread sensitive resources and accessing a resource in a multi-threaded environment requires to be thread-sa...
