(Caveat emptor: there are many, many programmers who go into absolute conniptions if they meet code that uses recordsets instead of commands and stored procedures.) <% dim rs, sql dim SelectedUser SelectedUser = request.form("user") if IsNumeric(SelectedUser) then SelectedUser...

Using UISettings, the appearance of the Google Map can be modified. Here is an example of some common settings: mGoogleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); mGoogleMap.getUiSettings().setMapToolbarEnabled(true); mGoogleMap.getUiSettings().setZoomControlsEnabled(true); mGoog...

A function declared inline may be defined in multiple translation units, provided that all definitions are identical. It also must be defined in every translation unit in which it is used. Therefore, inline functions should be defined in headers and there is no need to mention them in the implementa...

Once you understand how to create an HTTP Server with node, it's important to understand how to make it "do" things based on the path that a user has navigated to. This phenomenon is called, "routing". The most basic example of this would be to check if (request.url === 'some/pa...

$ mplayer Lecture_video_part1.mkv $ ^1^2^ mplayer Lecture_video_part2.mkv This command will replace 1 with 2 in the previously executed command. It will only replace the first occurrence of the string and is equivalent to !!:s/1/2/. If you want to replace all occurrences, you have to use !!:gs...

Phoenix framework is written in Elixir, and Elixir itself is based on Erlang language and leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems. Both languages are required for using phoenix framework. Following following step to install phoenix framework: 1...

Sometimes conversion of primitive types to boxed types is necessary. To convert the array, it's possible to use streams (in Java 8 and above): Java SE 8 int[] primitiveArray = {1, 2, 3, 4}; Integer[] boxedArray = Arrays.stream(primitiveArray).boxed().toArray(Integer[]::new); With lowe...

When state_below is a 2D Tensor, U is a 2D weights matrix, b is a class_size-length vector: logits = tf.matmul(state_below, U) + b return tf.nn.softmax(logits) When state_below is a 3D tensor, U, b as before: def softmax_fn(current_input): logits = tf.matmul(current_input, U) + b ret...

Use tf.nn.sparse_softmax_cross_entropy_with_logits, but beware that it can't accept the output of tf.nn.softmax. Instead, calculate the unscaled activations, and then the cost: logits = tf.matmul(state_below, U) + b cost = tf.nn.sparse_softmax_cross_entropy_with_logits(logits, labels) In this c...

Stream operations fall into two main categories, intermediate and terminal operations, and two sub-categories, stateless and stateful. Intermediate Operations: An intermediate operation is always lazy, such as a simple Stream.map. It is not invoked until the stream is actually consumed. This can...

Get all documents in the collection 'myCollection' and print them to the console. const MongoClient = require('mongodb').MongoClient; const url = 'mongodb://localhost:27017/test'; MongoClient.connect(url, function (err, db) { if (err) throw new Error(err); var cursor = db.collection('my...

You can use the plus (+) operator to concatenate strings: 'Dart ' + 'is ' + 'fun!'; // 'Dart is fun!' You can also use adjacent string literals for concatenation: 'Dart ' 'is ' 'fun!'; // 'Dart is fun!' You can use ${} to interpolate the value of Dart expressions within strings. The curly...

We are so used to the name D3.js that it's possible to forget that D3 is actually DDD (Data-Driven Documents). And that's what D3 does well, a data-driven approach to DOM (Document Object Model) manipulation: D3 binds data to DOM elements and manipulates those elements based on the bounded data. Le...

Use Spliterators.spliterator() or Spliterators.spliteratorUnknownSize() to convert an iterator to a stream: Iterator<String> iterator = Arrays.asList("A", "B", "C").iterator(); Spliterator<String> spliterator = Spliterators.spliteratorUnknownSize(itera...
