If a void* value is converted to a pointer to object type, T*, but is not properly aligned for T, the resulting pointer value is unspecified. Example: // Suppose that alignof(int) is 4 int x = 42; void* p1 = &x; // Do some pointer arithmetic... void* p2 = static_cast<char*>(p1) + 2; ...

Batch file command line arguments are parameter values submitted when starting the batch. They should be enclosed in quotes if they contain spaces. In a running batch file, the arguments are used for various purposes, i.e. redirection to :labels, setting variables, or running commands. The argument...

When more than 9 arguments are supplied, the shift [/n] command can be used, where /n means start at the nth argument, n is between zero and eight. Looping through arguments: :args set /a "i+=1" set arg!i!=%~1 call echo arg!i! = %%arg!i!%% shift goto :args Note, in the above exam...

Assuming you have Eclipse IDE for Java Developers installed, start Eclipse, click "Help" -> "Install New Software..." Select "--All Available Sites--" at "Work with:", and navigate to "Eclipse Plugin Development Tools". Select "Eclipse Pl...

Let's create an Enumerator for Fibonacci numbers. fibonacci = Enumerator.new do |yielder| a = b = 1 loop do yielder << a a, b = b, a + b end end We can now use any Enumerable method with fibonacci: fibonacci.take 10 # => [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]

To manipulate colors we will modify the argb (Alpha, Red, Green and Blue) values of a color. First extract RGB values from your color. int yourColor = Color.parse("#ae1f67"); int red = Color.red(yourColor); int green = Color.green(yourColor); int blue = Color.blue(yourColor); Now...

A few pre-requisites in the build.gradle for vectors to work all the way down to API 7 for VectorDrawables and API 13 for AnimatedVectorDrawables (with some caveats currently): //Build Tools has to be 24+ buildToolsVersion '24.0.0' defaultConfig { vectorDrawables.useSupportLibrary = true ...

(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...

$ mkdir backup_download_directory && cd !#:1 mkdir backup_download_directory && cd backup_download_directory This will substitute the Nth argument of the current command. In the example !#:1 is replaced with the first argument, i.e. backup_download_directory.

$ 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...

$ apt-get install r-base E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root? $ sudo !! sudo apt-get install r-base [sudo] password for <user>:

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...

ActionMailer also allows attaching files. attachments['filename.jpg'] = File.read('/path/to/filename.jpg') By default, attachments will be encoded with Base64. To change this, you can add a hash to the attachments method. attachments['filename.jpg'] = { mime_type: 'application/gzip', enco...

Using Ubuntu you have different ways to read a text file, all similar but useful in different context. cat This is the simplest way to read a text file; it simply output the file content inside the terminal. Be careful: if the file is huge, it could take some time to complete the printing process!...

With a clustered index the leaf pages contain the actual table rows. Therefore, there can be only one clustered index. CREATE TABLE Employees ( ID CHAR(900), FirstName NVARCHAR(3000), LastName NVARCHAR(3000), StartYear CHAR(900) ) GO CREATE CLUSTERED INDEX IX_Clustered O...

Non-clustered indexes have a structure separate from the data rows. A non-clustered index contains the non-clustered index key values and each key value entry has a pointer to the data row that contains the key value. There can be maximum 999 non-clustered index on SQL Server 2008/ 2012. Link for r...

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...

Generators are functions which are able to pause and then resume execution. This allows to emulate async functions using external libraries, mainly q or co. Basically it allows to write functions that wait for async results in order to go on: function someAsyncResult() { return Promise.resolve...
