Will talk about directory structure of CakePHP, what each folder means.

Errors, when managed properly by the server, will be returned to your client with a specific HTTP status code different from 2xx (see RFC 2616 section 10).
It's advised to catch globally your errors from your $.ajaxSetup() as demonstrated in the example below. Therefore all errors coming from your ...
Have you ever wondered how the search engines work? How does Google line-up millions of results in front of you in just a few milliseconds? How does a huge database situated thousands of miles away from you find out information you're searching for and send them back to you? The reason behind this i...
Using the NotificationCenter of iOS, which can be very powerful, you are able to intercept certain app-wide events:
NotificationCenter.default.addObserver(
self,
selector: #selector(ViewController.do(_:)),

In case of problems, enable the internal logger
<nlog internalLogFile="c:\log.txt" internalLogLevel="Trace">
<targets>
<!-- target configuration here -->
</targets>
<rules>
<!-- log routing rules -->
</rules>...
In case of problems, enable the internal logger.
C# example:
// set internal log level
InternalLogger.LogLevel = LogLevel.Trace;
// enable one of the targets: file, console, logwriter:
// enable internal logging to a file (absolute or relative path. Don't use layout renderers)
InternalL...
Sometimes we need to collect data from google spreadsheets. We can use gspread and oauth2client libraries to collect data from google spreadsheets. Here is a example to collect data:
Code:
from __future__ import print_function
import gspread

Elastic Beanstalk (EB) is essentially a hybrid between Golden AMIs and CloudFormation, while vastly simplifying the learning curve of Puppet or Chef.
An Elastic Beanstalk deployment is broken down into two components: Application and Environment.

Depth-first search is an algorithm for traversing or searching tree or graph data structures. One starts at the root and explores as far as possible along each branch before backtracking. A version of depth-first search was investigated in the 19th century French mathematician Charles Pierre Trémaux...

The Google Analytics API is split into serval parts.
