The Importance Of Remote Network Access For Businesses

It is not unusual for a business to own network equipment dispersed in various geographical areas that they need to keep a close eye on. Ensuring that all routers, servers and the rest of the network gear are running 24/7 well is mandatory for the well-being of all operations. However, this can be challenging for the IT department, especially when your staff is out of the office most of the time as part of the modern-day remote work trend. Some of your employees might be in the field most of the time, while others might choose to work from home. It is also possible for the actual IT staff to be working from a remote location. This is a scenario that is gaining more and more popularity nowadays, and it requires smooth access to a network for proper monitoring. Unfortunately, not all managers are able to provide their IT personnel with the network access they need from a remote location. The risk of security breaches continues to be one of the main obstacles in the way of remote network management practices. However, remote monitoring comes with a series of undeniable advantages we are going to introduce to you within these next few lines.

Keep An Eye On Your Remote Officesnetwork access

If you are running a business with several locations and offices spread all across the country/state/city, you could use remote network software for monitoring purposes and effectively manage all of your devices. Managing a restaurant chain with different local diners will be done a lot easier with the help of remote monitoring tools. You should be able to keep an eye on the performance of all the devices in all of your locations without too big of an effort. This software should also inform you whenever there are any performance issues you need to address.

It is possible to use tracking devices for network maps and make the difference between your various offices. This way, whenever a device will break down in one of your office or branch locations, you will be able to immediately access and fix it without having to physically travel to the respective location. You will not only be saving a lot of precious time, but you will also get to spend less on your network maintenance and troubleshooting.

Your Remote IT Staff Can Monitor The Network In Real-Time

In case your IT staff is the one that is located in one or several remote offices/areas, remote network access can help them remotely access all the performance data and parameters in real-time. With the help of network maps, a network engineer can see everything you are seeing on your computer and save time and energy on the actual troubleshoot, whenever there is a problem. You can focus on your management activities and let the pros do their job without too much or any interference in your regular schedule and tasks.

Since the IT staff you have hired does not necessarily need to be present in your offices on a continuous basis, you will enjoy a lot more freedom of movement in terms of work completion. You can choose to do your tasks from a coffee shop or from home and rely on remote network access to check the status of all of your devices using your laptop or smartphone.

Remote Network Access Can Boost Overall Security

If you are one of those managers who are particularly concerned about the risk of security attacks in relation to remote access to your network, you should be happy to learn there are good solutions for you. The use of encrypted authentication and customized user access will contribute to the lowering of this risk. It is also a good idea to use patches for security breaches and threats and get notifications whenever a new patch is released so you can take advantage of its improved benefits as soon as you can.

No matter if you are planning on setting up a fresh casino on the web like the ones here https://www.australia-casino.org/new-online-casinos and you need to keep an eye on eye on your network to avoid hacker attacks, or you are running several land poker or slots venues you need full control over, remote network access control is a must. As long as you can get access to your network with the help of a reliable VPN connection, you should be able to streamline your activity with more ease and avoid specific network issues that could cause interruptions.

Tips For Creating Simple Game Scripts

According to a study performed by a team from the University of Essex in the United Kingdom, people around the globe spend around three billion hours emerged in playing video games on a weekly basis. One of the most interesting findings of this study has revealed that players particularly enjoy playing different characters throughout the games. People enjoy acting and being the best version of themselves. Gamers tend to feel better about themselves when they can use different identities during games, be it the role of a villain or a character of the opposite gender. A shy person will test out a character with an open and more outgoing personality – and they will enjoy it.game script

Besides their obvious entertainment role, games can also educate us, teach us new skills, make us more patient or courageous, bring our traits we had no idea we had in us, make us more competitive or diligent/organized and the list goes on. So there is no wonder there are millions of video, casino, computer, puzzle, arcade, shooting, racing, or sport-related games out there – and even more being designed and created as we speak. People who create video game scripts have some of the most lucrative jobs, given the success of the gaming industry. If you are interested in starting a job in the game script writing field, these next few tips should be useful to you.

Games Need To Tell A Story

All games need to tell a story and engage the player in an interesting and captivating scenario that can keep them in front of the computer screen or smartphone/tablet touchscreen. A successful and popular game is one that relies on a complex world and gameplay. The longer it takes to advance through screens that run one after the other while slaying monsters and ghouls, complete quests, or reveal wild and scatter symbols during a casino slots game. Players need to be able to progress throughout a game and make a series of decisions that will bring them face to face with even more interesting scenarios. The more rich and complex a game, the more chances it has to be played and replayed all over again.

When writing a new script for a game, it can be useful to use similar elements used by movie script writers. Focus on writing an executive overview of the story using prose. Keep in mind this will be a determining factor that will establish the success or the failure of your game from day one. Tell a highly compelling story and make it as one-of-a-kind as possible. Do it step-by-step.  Write the detailed opening scene and capture the interest of new players, then carry them into the universe you have created with each new level and step of the process. Write around ten pages accurately describing all scenes and game details and do not hesitate to add elements of surprise and plots to change the natural course of the game when players least expect it. The overview will turn into the most critical part of game development, so you should take as much time writing it as possible.

Create Flowcharts For The Game

Players will need to make a series of decisions during the gameplay.  Make these decisions as numerous and complex/interesting as possible to keep them motivated to keep playing.  Each decision will open a brand new path for players. Have a detailed and constantly updated flowchart that will keep track of all of these paths and different options. While some games may rely on pure randomness and random number generators, which is the case of online roulette games for real money, others enable players to decide what should happen next – which path or quest to go on, which weapons to use and so on. Sub-quests are also important for a game script. They can either be simple or complex and they must also tell a story on their own.

Your characters should also be described with the help of bios and character descriptions. Casino games that feature various themes such as sports, pets, superheroes, Ancient Egypt, horror or fruit, also feature various characters that can pop up throughout the game during special bonus rounds. They can tell a convincing story and guide players to the next rounds and levels of the game, bring them free spins and special symbols and more. While gamblers enjoy the thrill of wagering their money on an outcome they cannot anticipate with the desire to win, they also like top-notch graphics and multiple gameplay options, quality sounds and designs and anything that can help them stay engaged.

Mysql crash problems on EC2 AWS micro instance

If you have the default mysql config probably you’ll have some crash problems after a while running the instance.

I’m running a micro instance, with Ubuntu 12.04 and default mysql installation.

I’ve this logs reports:

[Note] Plugin 'FEDERATED' is disabled.
InnoDB: The InnoDB memory heap is disabled
InnoDB: Mutexes and rw_locks use GCC atomic builtins
InnoDB: Compressed tables use zlib 1.2.7
InnoDB: Using Linux native AIO
InnoDB: Initializing buffer pool, size = 128.0M
InnoDB: mmap(137363456 bytes) failed; errno 12
InnoDB: Completed initialization of buffer pool
InnoDB: Fatal error: cannot allocate memory for the buffer pool
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] Unknown/unsupported storage engine: InnoDB
[ERROR] Aborting

[Note] /usr/sbin/mysqld: Shutdown complete

 

To solve it you need to add some lines on the /etc/mysql/my.cnf file after the [mysql] line:

innodb_buffer_pool_size = 40M
key_buffer_size=10M
max_connections=5

Also it’s recommended to run a repair table on each of your databases after changing the mysql settings and restart the mysqld service.

Git keep asking for my username and password on GitHub

If you’re experiencing this problem maybe you’ve made the checkout with the http or https url, that means that you dont have an authentication method.

For linux or Mac you can solve it with a simple way.

Mac:

    git config --global credential.helper osxkeychain

Linux:

    git config credential.helper cache

Reference for cache options on this link http://git-scm.com/docs/git-credential-cache

If you’re on windows and you’re trying to use cache the cache helper you might have the next message:

    git: 'credential-cache' is not a git command. See 'git --help'.

So in that case you need to setup the ssh connection and change your remote protocol connection from http to ssh. To do that you need run:

    git remote set-url origin git@github.com:username/repo-url-on-github.git

You also need to setup your ssl-key you can do it from the GitHub config https://github.com/settings/ssh . If you don’t know how to generate ssh keys just follow these steps https://help.github.com/articles/generating-ssh-keys .

How to use Dropbox as a GIT repository

Don’t you ever setup another version control server, Mercurial, SVN, CVS, or any other you may know.

What is GIT?

“In software development, Git /ɡɪt/ is a distributed version control and source code management (SCM) system with an emphasis on speed. Initially designed and developed by Linus Torvalds for Linux kernel development, Git has since been adopted by many other projects.”

Git on Wikipedia

What is Dropbox

“Dropbox is a file hosting service operated by Dropbox, Inc., that offers cloud storage, file synchronization, and client software. Dropbox allows users to create a special folder on each of their computers, which Dropbox then synchronizes so that it appears to be the same folder (with the same contents) regardless of which computer is used to view it. Files placed in this folder also are accessible through a website and mobile phone applications.”

How to setup a GIT repo into your Dropbox account

Of course most of you already know what is GIT or Dropbox, so let’s start with the cool part of the post. Obiously you need to have Drobox and GIT installed on you PC or laptop.

1. First you need to create an empty folder on your Dropbox.

:~$ cd Dropbox
:Dropbox$ mkdir project_name

2. Init the remote folder into your local Dropbox

:Dropbox$ cd project_name/
:project_name$ git init --bare
Initialized empty Git repository in /Users/zantez/Dropbox/project_name/

Perform an ls command and you’ll see some folders

[BARE:master]:project_name$ ls
HEAD config description hooks info objects refs

3. Now lets clone the current GIT repository to a destination on your PC or laptop

:git$ git clone ~/Dropbox/project_name project_name_local
Cloning into 'project_name_local'...
warning: You appear to have cloned an empty repository.
done. 
:git$ cd project_name_local/ [master]:project_name_local$

4. Let’s perform an initial commit and push it into the origin

[master]:project_name_local$ ls test.txt
[master]:project_name_local$ git add -A
[master]:project_name_local$ git ci -m "initial commit"
[master (root-commit) 6916e97] initial commit 1 file changed, 0 insertions(+), 0 deletions(-) create mode
    100644 test.txt
[master]:project_name_local$ git push origin master Counting objects: 3, done.
Writing objects: 100% (3/3),

How to create infinite scroll with ajax on jQuery

Nowadays almost every page with dynamic news use infinite scroll, Twitter, Facebook and Pinterest are the main references for this.

It’s very practical when you have unstructured information, timed and loaded dynamically. Gives the sensation to the user that the information never ends, but also you can have some troubles if the user wants to have indented information, so be careful not always is the best choice for your user experience.

You can use some jQuery plugins, like paulrish / infinite scroll plugin ( https://github.com/paulirish/infinite-scroll ) or jScroll ( http://jscroll.com/ ). If you are those who want to do it themselves, just follow these steps to start from scratch your own jQuery infinite scroll piece of work.

If you want to make it yourself here you’ve a starting point, create a function to check if the last element of your list is on the current scroll position:

function element_in_scroll(elem)
{
    var docViewTop = $(window).scrollTop();
    var docViewBottom = docViewTop + $(window).height();

    var elemTop = $(elem).offset().top;
    var elemBottom = elemTop + $(elem).height();

    return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop));
}

Now we need to setup the scroll event ( http://api.jquery.com/scroll/ ) and check if the element we want to trigger the ajax request is visible to the user:

$(document).scroll(function(e){
	//...
});

Inside of this event, call the element_in_scroll function and use the selector ( http://api.jquery.com/selector/ ) you want, in this case I’m using an html table

<table class="errors">
    <tbody>
        <tr>
            <td><span class="label label-error" >ERROR</span></td>
            <td class="collapse"><span class="label label-warning" >Warning</span></td>
            <td class="collapse">example error</td>
            <td class="date collapse">2013-05-26 23:54:19</td>
        </tr>
    </tbody>
</table>

So for this html you need to use this jQuery selector:

$(document).scroll(function(e){
	if (element_in_scroll(".errors tbody tr:last")) {
			//Here you must do what you need to achieve the infinite scroll effect...
		};
});

I’ve used an ajax request to perform the infinite scroll completion, here’s the complete scroll event call with the ajax request:

$(document).scroll(function(e){
	if (element_in_scroll(".errors tbody tr:last")) {
			$(document).unbind('scroll');
			$.ajax({
				type: "POST",
				url: document.location.href,
				data: { text_filter:  $('#text_filter').attr('value'), index_count:$('#index_count').attr('value'),json: "true" }
			}).done(function( msg ) {
				$(".errors tbody ").append(msg.html);
				$('#index_count').attr('value',msg.index_count);
				if (msg.count != 0) {
					$(document).scroll(function(e){
						//callback to the method to check if the user scrolled to the last element of your list/feed 
					})
				}
			});
		};
});

The data attributes are the references to know what page is needed, you can also use a timestamp depending on how are you saving your information. When msg.count is equal to zero, the scroll event is disabled.

Simple PHP Code Igniter class to show the error log

Sometimes we need to acces the php log, but is not available on the document root, so yo need to access by console or create a symlink to some part inside the public folder of your website. Also you need to add some credentials in order to protect your logs. This is a simple and safer way to access your php error log, you can add this controller inside your protected controllers using the php session or maybe a cookie generated by you with some encrypted data.

So here is the controller class to show the php log really easy for code igniter Zurich Prime reviews.

<?php
/**
 * Php Log class
 *
 * Display the php log
 *
 * @category	Log
 * @author		Nicolás Bistolfi
 * @link		https://dl.dropboxusercontent.com/u/20596750/code/php/log.php
 */
class Log extends Controller{

	private $logPath; //path to the php log
	/**
	*	Class constructor
	*/
	function __construct(){
		parent::Controller();
		$this->logPath = ini_get('error_log');
	 }

	/**
	 * index: Shows the php error log
	 * @access public
	 */
	public function index(){
		if (@is_file($this->logPath)) {
			echo nl2br(@file_get_contents($this->logPath));

			echo 'The log cannot be found in the specified route '.$this->logPath;
		}
		exit;
	}

	/**
	 * delete: Deletes the php error log

How to backup MySQL database from the command line

Backup your MySQL database to an sql file with your command line. Using native mysql client and tools you can perform all the backup and restore operations you need.

First you need to have installed the command line tools, in this case mysqldump.

$ mysqldump --opt -u [uname] -p [dbname] > [backupfile.sql]
  • [uname] Your database username
  • [pass] The password for your database (note there is no space between -p and the password)
  • [dbname] The name of your database
  • [backupfile.sql] The filename for your database backup
  • [–opt] The mysqldump option

Example if you have a database called wordpress_blog you only have to do this:

$ mysqldump --opt -u root -p wordpress_blog > wordpress_blog_bk.sql

If you want to backup all the databases in only one sql file you can use –all-databases option

$ mysqldump -u root -p --all-databases > alldb_backup.sql
