Update your project with git pull origin master Update s.version inside MyRepo.podspec Check local errors with pod lib lint MyRepo.podspec git add . & git commit -m "Update pods version" git push origin master Make a new release pod trunk push MyRepo.podspec Source

You will need to set your base URL in application/config/config.php If it is not set, then CodeIgniter will try to guess the protocol and path to your installation, but due to the security concerns the hostname will be set to $_SERVER['SERVER_ADDR'] if available, or localhost otherwise. The auto...

Single file plugin Put the file under $HOME/.vim/plugin or $HOME/vimfiles/plugin This would source the plugin on startup of Vim. Now the user could use everything defined in it. If the plugin however needs activation, the user either has to execute the command themselves whenever they want to use...

Setup First, install the necessary packages with: npm install express cors mongoose Code Then, add dependencies to server.js, create the database schema and the name of the collection, create an Express.js server, and connect to MongoDB: var express = require('express'); var cors = require('...

A Scripting Dictionary object stores information in Key/Item pairs. The Keys must be unique and not an array but the associated Items can be repeated (their uniqueness is held by the companion Key) and can be of any type of variant or object. A dictionary can be thought of as a two field in-memory ...

A source code file is a (generally) plain text file which is to processed by the compiler. A source code file may contain up to one main program and any number of modules and external subprograms. For example, a source code file may contain the following module mod1 end module mod1 module mod...

In an enum it is possible to define a specific behavior for a particular constant of the enum which overrides the default behavior of the enum, this technique is known as constant specific body. Suppose three piano students - John, Ben and Luke - are defined in an enum named PianoClass, as follows:...

When Intel designed the original x86, the 8086 (and 8088 derivative), they included Segmentation to allow the 16-bit processor to access more than 16 bits worth of address. They did this by making the 16-bit addresses be relative to a given 16-bit Segment Register, of which they defined four: Code S...

Introduction When the 80286 was invented, it supported the legacy 8086 Segmentation (now called "Real Mode"), and added a new mode called "Protected Mode". This mode has been in every x86 processor since, albeit enhanced with various improvements such as 32- and 64-bit addressin...

Switching into Protected Mode is easy: you just need to set a single bit in a Control Register. But staying in Protected Mode, without the CPU throwing up its hands and resetting itself due to not knowing what to do next, takes a lot of preparation. In short, the steps required are as follows: ...

Overview The Rigidbody component gives a GameObject a physical presence in the scene in that it is able to respond to forces. You could apply forces directly to the GameObject or allow it to react to external forces such as gravity or another Rigidbody hitting it. Adding a Rigidbody component Y...

Most programming languages, including F#, evaluate computations immediately in accord with a model called Strict Evaluation. However, in Lazy Evaluation, computations are not evaluated until they are needed. F# allows us to use lazy evaluation through both the lazy keyword and sequences. // define ...

F#, like most programming languages, uses Strict Evaluation by default. In Strict Evaluation, computations are executed immediately. In contrast, Lazy Evaluation, defers execution of computations until their results are needed. Moreover, the results of a computation under Lazy Evaluation are cached,...

Partial method consists of the definition in one partial class declaration (as a common scenario - in the auto-generated one) and the implementation in another partial class declaration. using System; namespace PartialClassAndMethods { public partial class PartialClass // Auto-generated ...

With a column of one of the string types, named my_date_field with a value such as [the string] 07/25/2016, the following statement demonstrates the use of the STR_TO_DATE function: SELECT STR_TO_DATE(my_date_field, '%m/%d/%Y') FROM my_table; You could use this function as part of WHERE clause a...

From command line: cpan -l From a Perl script: use ExtUtils::Installed; my $inst = ExtUtils::Installed->new(); my @modules = $inst->modules();

Simple one-liners may be specified as command line arguments to perl using the -e switch (think "execute"): perl -e'print "Hello, World!\n"' Due to Windows quoting rules you can't use single-quoted strings but have to use one of these variants: perl -e"print qq(Hello, W...

It is good practice to test the calling program's __name__ variable before executing your code. import sys def main(): # Your code starts here # Don't forget to provide a return code return 0 if __name__ == "__main__": sys.exit(main()) Using this pattern ens...

I always think it is nice to have a very simple, self-contained example so that nothing is assumed when I am learning a new task. This answer is that for deleting UITableView rows. The project performs like this: This project is based on the UITableView example for Swift. Add the Code Create a ...

Preallocation. Mongo sets aside disk-space in empty containers, so when the time comes to write something to disk, it doesn't have to shuffle bits out of the way first. It does so by a doubling algorithm, always doubling the amount of disk space preallocated until it reaches 2GB; and then each preal...
