You could migrate from team foundation version control to git by using an open source tool called Git-TF. Migration will also transfer your existing history by converting tfs checkins to git commits. To put your solution into Git by using Git-TF follow these steps: Download Git-TF You can downloa...

A good VOD (Video On Demand) service should start with the basics. Lets say you have a directory on your server that is not publicly accessible, yet through some sort of portal or paywall you want to allow users to access your media. var movie = path.resolve('./public/' + req.params.filename); ...

Implement onMessageReceived that will catch the notification sent from GCM server. @Override public void onMessageReceived(String from, Bundle data) { String message = data.getString("message"); Log.d(TAG, "From: " + from); Log.d(TAG, "Message: "...

To receive the notification, implement application:didReceiveRemoteNotification:fetchCompletionHandler: (or application:didReceiveRemoteNotification: for iOS < 8.0), and call GCMService:appDidReceiveMessage:message to acknowledge the reception of the message to GCM. - (void)application:(UIApplic...

This writeup walks though steps to configure Tomcat to request CAC certificates from the client. It is focused on setting up a development environment, so some features that should be considered for production are not here. (For example it shows using a self-signed certificate for https and it does...

Use conditional compilation to ensure that code only compiles for the intended instruction set (such as x86). Otherwise code could become invalid if the program is compiled for another architecture, such as ARM processors. #![feature(asm)] // Any valid x86 code is valid for x86_64 as well. Be ca...

#![feature(asm)] #[cfg(any(target_arch="x86", target_arch="x86_64"))] fn subtract(first: i32, second: i32) { unsafe { // Output values must either be unassigned (let result;) or mutable. let result: i32; // Each value that you pass in will b...

The following example is high level coverage of the key concepts and basic skeletal setup:- Collects credentials from the user (Usually from a login screen you've created) Authenticates the credentials with the server (stores custom authentication) Stores the credentials on the device Exte...

JavaFX has a binding API, which provides ways of binding one property to the other. This means that whenever one property's value is changed, the value of the bound property is updated automatically. An example of simple binding: SimpleIntegerProperty first =new SimpleIntegerProperty(5); //create a...

Case 1: While using in the place of method arguments. If a method requires an object of wrapper class as argument.Then interchangeably the argument can be passed a variable of the respective primitive type and vice versa. Example: int i; Integer j; void ex_method(Integer i)//Is a valid statem...

Jersey (2) uses HK2 as its dependency injection (DI) system. We can use other injection systems, but its infrastructure is built with HK2, and allows us to also use it within our applications. Setting up simple dependency injection with Jersey takes just a few lines of code. Let say for example we ...

Spring Boot is a bootstrapping framework for Spring applications. It has seamless support for integrating with Jersey also. One of the advantages of this (from the perspective of a Jersey user), is that you have access to Spring's vast ecosystem. To get started, create a new standalone (non-wepapp)...

The pandas.DataFrame.apply() method is used to apply a given function to an entire DataFrame --- for example, computing the square root of every entry of a given DataFrame or summing across each row of a DataFrame to return a Series. The below is a basic example of usage of this function: # create...

The iv is prefixed to the encrypted data aesCBC128Encrypt will create a random IV and prefixed to the encrypted code. aesCBC128Decrypt will use the prefixed IV during decryption. Inputs are the data and key are Data objects. If an encoded form such as Base64 if required convert to and/or from in ...

A very handy way to subset Time Series is to use partial string indexing. It permits to select range of dates with a clear syntax. Getting Data We are using the dataset in the Creating Time Series example Displaying head and tail to see the boundaries se.head(2).append(se.tail(2)) # 2016-09-2...

When you need to find the bounding rectangle of a quadratic bezier curve you can use the following performant method. // This method was discovered by Blindman67 and solves by first normalising the control point thereby reducing the algorithm complexity // x1,y1, x2,y2, x3,y3 Start, Control, and ...

react-rails includes a view helper (react_component) and an unobtrusive JavaScript driver (react_ujs) which work together to put React components on the page. You should require the UJS driver in your manifest after react (and after turbolinks if you use Turbolinks). The view helper puts a div on t...
