Bridge Mode $ docker run –d –-name my_app -p 10000:80 image_name Note that we did not have to specify --net=bridge because this is the default working mode for docker. This allows to run multiple containers to run on same host without any assignment of dynamic port. So BRIDGE mode avoids the por...

Another common type of loop in Visual Basic is the DO loop, which would run a piece of code continuously until it is told to stop. On the contrary of some other loops whereby indexes are used to stop the process, in this particular loop, it should be told to stop. A simple example illustrating the ...

Dialog dlg; DialogGroup dGrp; DialogField dfName; dlg = new Dialog("Trivial Dialog"); dGrp = dlg.addGroup("A Group"); dfName = dlg.addField(extendedTypeStr(Name)); if (dlg.run()) { info(dfName.value()); } Extended data types have to be wrapped in a call to ext...

Dialog dlg; DialogGroup dGrp; DialogField dfCustomer; dlg = new Dialog("Simple Dialog"); dGrp = dlg.addGroup("A Group"); dfCustomer = dlg.addField(extendedTypeStr(CustAccount)); if (dlg.run()) { info(dfCustomer.value()); } Because CustAccount is linked to the ...

Dialog dlg; DialogGroup dGrp; DialogField dfGender; dlg = new Dialog("Enum Dialog"); dGrp = dlg.addGroup("A Group"); dfGender = dlg.addField(enumStr(Gender), "Your Gender"); if (dlg.run()) { info(dfGender.value()); } Enums have to be wrapped inside a...

Dialog dlg; DialogGroup dGrp; DialogField dialogField; dlg = new Dialog("Evil Dialog"); dGrp = dlg.addGroup("A Group"); dialogField = dlg.addFieldValue(extendedTypeStr(NoYesId), NoYes::Yes, "I hereby sell my soul"); if (dlg.run()) { info(dialogField.valu...

The first example are keywords that have a special purpose in C++: the following is legal in C, but not C++. int class = 5 These errors are easy to fix: just rename the variable.

In C, pointers can be cast to a void*, which needs an explicit cast in C++. The following is illegal in C++, but legal in C: void* ptr; int* intptr = ptr; Adding an explicit cast makes this work, but can cause further issues.

Create a new rails app hello-world from command in Windows and Terminal in Linux. rails new hello-world Now move to new app directory cd hello-world Now generate a controller rails generate controller hello_world index Here index is the name of method in hello_world controller. You can c...

For this example, let model be a Keras model for classifying video inputs, let X be a large data set of video inputs, with a shape of (samples, frames, channels, rows, columns), and let Y be the corresponding data set of one-hot encoded labels, with a shape of (samples, classes). Both datasets are s...

Foreign Keys constraints ensure data integrity, by enforcing that values in one table must match values in another table. An example of where a foreign key is required is: In a university, a course must belong to a department. Code for the this scenario is: CREATE TABLE Department ( Dept_Code...

Using yield break as opposed to break might not be as obvious as one may think. There are lot of bad examples on the Internet where the usage of the two is interchangeable and doesn't really demonstrate the difference. The confusing part is that both of the keywords (or key phrases) make sense only...

For this example, let's assume that the inputs have a dimensionality of (frames, channels, rows, columns), and the outputs have a dimensionality of (classes). from keras.applications.vgg16 import VGG16 from keras.models import Model from keras.layers import Dense, Input from keras.layers.pooling...

Creating app project When creating an Android app ready for the app store it's important when using ionic start that we add --appname|-a and --id|-i flags which is used for google play to identify your app from other apps. If you're starting a new mobile app project you can use the cli example b...

Now open the document using OpenXML, you must add an imagePart that references the picture object to the MainDocumentPart object by using a file stream, and get the ID of the image string temp; MainDocumentPart mainPart = document.MainDocumentPart; ImagePart ima...

Now you have a reference of the image. Insert the image into the shapes in the template document. To do this, you will have to use some LINQ to iterate through the document and get a reference to all the shapes in the document. The wps:spPr element you see in the above XML code is the xml element fo...

A DataTrigger can be attached to any property, be it on it's own control, another control, or even a property in a non UI class. Consider the following simple class. public class Cheese { public string Name { get; set; } public double Age { get; set; } public int StinkLevel { get; s...

You can choose to prepend an if or else operator with a dash, but it is not necessary. You will need to wrap the statement in parentheses, though (if you omit a dash, you do not need parentheses.) - var showLogin = false; - if (showLogin === true) .welcome Welcome back to our website! - else...
