TFRecord files is the native tensorflow binary format for storing data (tensors). To read the file you can use a code similar to the CSV example: import tensorflow as tf filename_queue = tf.train.string_input_producer(["file.tfrecord"], num_epochs=1) reader = tf.TFRecordReader() key, s...
QObjects come with their own alternative lifetime concept compared to native C++'s raw,unique or shared pointers. QObjects have the possibility to build an objecttree by declaring parent/child relationships. The simplest way to declare this relationship is by passing the parent object in the const...
Of course you can pass data to Sinatra routes, to accept data in your routes you can add route paremeters. You can then access a params hash: get '/hello/:name' do # matches "GET /hello/foo" and "GET /hello/bar" # params['name'] is 'foo' or 'bar' "Hello #{params['...

This example adds a new parameter to MyTestFunction if $SomeUsefulNumber is greater than 5. function MyTestFunction { [CmdletBinding(DefaultParameterSetName='DefaultConfiguration')] Param ( [Parameter(Mandatory=$true)][int]$SomeUsefulNumber ) DynamicParam {...

The local configuration of sane is inside /etc/saned.d /etc/sane.d/dll.conf # /etc/sane.d/dll.conf - Configuration file for the SANE dynamic backend loader # # Backends can also be enabled by configuration snippets under # /etc/sane.d/dll.d directory -- packages providing backends should drop...
Is good practice to resist the temptation of doing the delete action in the get request. It would be a huge security error, it has to be done always in the post method. // GET: Student/Delete/5 public ActionResult Delete(int? id) { // it good practice to consider that things...
This example gets a listing of files from the provided zip archive binary data: public static Dictionary<string, byte[]> GetFiles(byte[] zippedFile) { using (MemoryStream ms = new MemoryStream(zippedFile)) using (ZipArchive archive = new ZipArchive(ms, ZipArchiveMode.Read)) ...
First why we should use depedency injection in our code ? We want to decouple other components from other classes in our program. For example we have class AnimalController which have code like this : public class AnimalController() { private SantaAndHisReindeer _SantaAndHisReindeer = new San...
VI snippets are like Screenshots of a Block Diagram, with one important difference. They can be opened in LabVIEW to reconstruct the orginal program. They are saved in the common .PNG format so they can be used like normal pictures e.g. in forums and on StackOverflow. To create a VI snippet mark th...
Let's say that you have exam scores for several exams and you want to divide them into quartiles per exam. -- Setup data: declare @values table(Id int identity(1,1) primary key, [Value] float, ExamId int) insert into @values ([Value], ExamId) values (65, 1), (40, 1), (99, 1), (100, 1), (90, 1), ...
public static Expression<Func<T, bool>> GetExpression<T>(IList<QueryFilter> filters) { Expression exp = null; // Represents a named parameter expression. {parm => parm.Name.Equals()}, it is the param part // To create a ParameterExpression need the ty...
For one filter: Here is where the query is created, it receives a expression parameter and a filter. private static Expression GetExpression<T>(ParameterExpression param, QueryFilter queryFilter) { // Represents accessing a field or property, so here we are accessing for example: ...
ConstantExpression must be the same type of the MemberExpression. The value in this example is a string, which is converted before creating the ConstantExpression instance. private static ConstantExpression GetConstant(Type type, string value) { // Discover the type, convert it, and create Co...
In this very first example, a basic serial write operation is started from an Arduino device. void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: Serial.println("Hello World!"); dela...
/** *@NApiVersion 2.x *@NScriptType Suitelet */ define([],function() { // NetSuite's AMD pattern function onRequest_entry(context) { // Suitelet entry function receives a context obj context.response.write('Hello World'); // Write a response using the context obj } retu...
The simplest composite type is an immutable type. Instances of immutable types, like tuples, are values. Their fields cannot be changed after they are created. In many ways, an immutable type is like a Tuple with names for the type itself and for each field. Singleton types Composite types, by def...
Scenario: You need to select an implementation of address validation when a sales order is submitted, and the validator is determined by the country to which the order is shipping. The factory needs to inspect some value passed as an argument to select the correct implementation. First, write an in...
Scenario: You need to resolve a dependency when a method is called, not in the constructor. Solution: Inject an abstract factory into the constructor. When the method is called, it requests the dependency from the abstract factory, which in turn resolves it from the container. (Your class depends o...
