If you want to get the versioned project's data, but you don't need any of the version control capabilities offered by Subversion, you could run svn export <URL> command. Here is an example:
$ svn export https://svn.example.com/svn/MyRepo/MyProject/trunk
As a result, you will get the proje...
You are not the only person working on the project, right? This means that your colleagues are also making modifications to the project's data. To stay up to date and to fetch the modifications committed by others, you should run svn update command in your working copy. As a result, your working cop...
A a pointer to a piece of memory containing n elements may only be dereferenced if it is in the range memory and memory + (n - 1). Dereferencing a pointer outside of that range results in undefined behavior. As an example, consider the following code:
int array[3];
int *beyond_array = array + 3;
...
git log -S"#define SAMPLES"
Searches for addition or removal of specific string or the string matching provided REGEXP. In this case we're looking for addition/removal of the string #define SAMPLES. For example:
+#define SAMPLES 100000
or
-#define SAMPLES 100000

If a remote branch has been deleted, your local repository has to be told to prune the reference to it.
To prune deleted branches from a specific remote:
git fetch [remote-name] --prune
To prune deleted branches from all remotes:
git fetch --all --prune
A wide variety of standard library functions have among their effects copying byte sequences from one memory region to another. Most of these functions have undefined behavior when the source and destination regions overlap.
For example, this ...
#include <string.h> /* for memcpy() */

Requirements: OS X 10.8 “Mountain Lion” or newer required to run Docker.
While the docker binary can run natively on Mac OS X, to build and host containers you need to run a Linux virtual machine on the box.

Since version 1.12 you don't need to have a separate VM to be installed, as Docker...
To uninstall one or more locally installed packages, use:
npm uninstall <package name>
The uninstall command for npm has five aliases that can also be used:
npm remove <package name>
npm rm <package name>
npm r <package name>
npm unlink <package name>
npm un ...
A group is a section of a regular expression enclosed in parentheses (). This is commonly called "sub-expression" and serves two purposes:
It makes the sub-expression atomic, i.e. it will either match, fail or repeat as a whole.
The portion of text it matched is accessible in the remai...
Since Groups are "numbered" some engines also support matching what a group has previously matched again.
Assuming you wanted to match something where two equals strings of length three are divided by a $ you'd use:
(.{3})\$\1
This would match any of the following strings:
"abc$...
Deleting the last element:
std::vector<int> v{ 1, 2, 3 };
v.pop_back(); // v becomes {1, 2}
Deleting all elements:
std::vector<int> v{ 1, 2, 3 };
v.clear(); // v becomes an empty vector
Deleting element by index:
std::vect...
See full documentation on LIKE operator.
This example uses the Employees Table from the Example Databases.
SELECT *
FROM Employees
WHERE FName LIKE 'John'
This query will only return Employee #1 whose first name matches 'John' exactly.
SELECT *
FROM Employees
WHERE FName like 'John%'

In standard pattern matching, the identifier used will shadow any identifier in the enclosing scope. Sometimes it is necessary to match on the enclosing scope's variable.
The following example function takes a character and a list of tuples and returns a new list of tuples. If the character existed...
Branching in Subversion is very simple. In the simplest form, creating a new branch requires you to run the command against the remote repository's URLs. For example, let's create a new branch out of the mainline trunk:
svn copy https://svn.example.com/svn/MyRepo/MyProject/trunk https://svn.example...
When you interact with the remote central repository using your private local workspace -- the working copy -- you can use repository-relative URL instead of direct URL to URL copy to create a new branch:
svn copy "^/MyProject/trunk" "^/MyProject/branches/MyNewBranch" -m "C...
The working copy (WC) is your local and private workspace that you use to interact with the central Subversion repository. You use the working copy to modify the contents of your project and fetch changes committed by others.
The working copy contains your project's data and looks and acts like a r...
Before publishing a package you have to version it. npm supports semantic versioning, this means there are patch, minor and major releases.
For example, if your package is at version 1.2.3 to change version you have to:
patch release: npm version patch => 1.2.4
minor release: npm version min...
Delete a file asynchronously:
var fs = require('fs');
fs.unlink('/path/to/file.txt', function(err) {
if (err) throw err;
console.log('file deleted');
});
You can also delete it synchronously*:
var fs = require('fs');
fs.unlinkSync('/path/to/file.txt');
console.log('file deleted'...
