If your application is going to run on different devices, it's going to need to render to different ViewPorts, based on the device size. You can deal with this in two ways: with javascript rules, or CSS media styles. If you've been using a MVC or MVVM library, such as Angular or Ember (or Blaze, for...

Make sure your development workstation and iPhone are connected to the same WiFi network. Tethering, hotspots, and other ad-hoc networking won't work. Run sudo meteor run ios-device Deploy to your device!

This command will create a /dump directory, and store each collection in a separate BSON blob file. This is the best way to backup or transfer databases between systems. mongodump --db meteor

public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent intent = getIntent(); Uri data = intent.getData(); if (d...

$ git show dae86e1950b1277e545cee180551750029cfe735 $ git show dae86e19 You can specify revision (or in truth any object: tag, tree i.e. directory contents, blob i.e. file contents) using SHA-1 object name, either full 40-byte hexadecimal string, or a substring that is unique to the repository. ...

$ git show # equivalent to 'git show HEAD' 'HEAD' names the commit on which you based the changes in the working tree, and is usually the symbolic name for the current branch. Many (but not all) commands that take revision parameter defaults to 'HEAD' if it is missing.

$ git reset --hard HEAD^ # discard last commit $ git rebase --interactive HEAD~5 # rebase last 4 commits A suffix ^ to a revision parameter means the first parent of that commit object. ^<n> means the <n>-th parent (i.e. <rev>^ is equivalent to <rev>^1). A...

In some cases the behavior of a command depends on whether it is given branch name, tag name, or an arbitrary revision. You can use "de-referencing" syntax if you need the latter. A suffix ^ followed by an object type name (tag, commit, tree, blob) enclosed in brace pair (for example v0.9...

$ git show HEAD^{/fix nasty bug} # find starting from HEAD $ git show ':/fix nasty bug' # find starting from any branch A colon (':'), followed by a slash ('/'), followed by a text, names a commit whose commit message matches the specified regular expression. This name returns the younge...

If we consider a heterogenous list, wherein the elements of the list have varied but known types, it might be desirable to be able to perform operations on the elements of the list collectively without discarding the elements' type information. The following example implements a mapping operation ov...

When a page is part of a series of articles, for instance, one can use prev and next to point to pages that are coming before and after. <link rel="prev" href="http://stackoverflow.com/documentation/java/topics"> <link rel="next" href="http://stackover...

To print the value of a pointer to an object (as opposed to a function pointer) use the p conversion specifier. It is defined to print void-pointers only, so to print out the value of a non void-pointer it needs to be explicitly converted ("casted*") to void*. #include <stdlib.h> /*...

Sometimes we need to fetch and print the value of a TensorFlow variable to guarantee our program is correct. For example, if we have the following program: import tensorflow as tf import numpy as np a = tf.Variable(tf.random_normal([2,3])) # declare a tensorflow variable b = tf.random_normal([2...

In order to print the value of a variable such as, set tempVar "This is a string." The argument in the puts statement is preceded by a $ sign, which tells Tcl to use the value of the variable. % set tempVar "This is a string." This is a string. % puts $tempVar This is a s...

This example describes how to create a SurfaceView with a dedicated drawing thread. This implementation also handles edge cases such as manufacture specific issues as well as starting/stopping the thread to save cpu time. import android.content.Context; import android.graphics.Canvas; import and...

If a class raises a large the number of events, the storage cost of one field per delegate may not be acceptable. The .NET Framework provides event properties for these cases. This way you can use another data structure like EventHandlerList to store event delegates: public class SampleClass { ...

Subtracting the values of two pointers to an object results in a signed integer *1. So it would be printed using at least the d conversion specifier. To make sure there is a type being wide enough to hold such a "pointer-difference", since C99 <stddef.h> defines the type ptrdiff_t. ...

You can evaluate any valid C# code: int value = await CSharpScript.EvaluateAsync<int>("15 * 89 + 95"); var span = await CSharpScript.EvaluateAsync<TimeSpan>("new DateTime(2016,1,1) - DateTime.Now"); If type is not specified, the result is object: object value = ...
