How it works

This plugin born with a request from a client, My client had seen this effect working in other websites, get this plugin working with this effect in the client site was fast but was a very hard work make a WordPress plugin with him, that is my first plugin and if you have any suggestion i’m open to listen you.

If you want know about this plugin i’m created a page in this blog to share the information about them and others plugins (i hope write more).

This plugin is very simple but it serverd me to learn how make a WordPress plugin and I’m sure I’ll go as I am becoming more actively working with WordPress at the moment.

Installing Zpanel + varnish over Centos 6.4

by Edwind Richzendy Contreras Soto on Tuesday September 10th, 2013

Testing the software asciiio which allows video recording in the terminal session and post it on web, I made a video where I show how install ZPanel in his last version and Varnish to make cache and serve pages faster.

All files served by varnish and are stored in its cache will not be counted for the statistics of spending ZPanel bandwidth because these requests do not go to apache server and the apache logs are used to make these statistics.

If you can not see the embeded, direct link to video: http://ascii.io/a/5378

Looking laboratory hardware virtualization

AMD A8-3870K, Xion XON-720P_RD - System Build - PCPartPicker Canada 2013-07-08 11-26-50
I am currently looking to buy some hardware, maybe two computers that I can serve to have a home lab to virtualize, test applications and various operating systems, ie testing with XenServer, Proxmox-VE, OpenVZ, VMware (why not ?), have my own lab migration from Microsoft services such as Exchange, Active Directory to OpenSource alternatives, perhaps to test compilation of programs without having to do it on my personal computer and especially to test clustering.

I need to be well cheap (maybe less than $300), but also the best quality/price ratio (also not to buy the cheapest and that is of poor quality), I need to have the highest level of processing as usually going to have some tests virtual machines (not in production) and neither have a lot of RAM, but if the opportunity to expand if necessary, need not hard disk because I have a couple of laptops hard drives that do not I can use or PXE loading operating system or through a USB and have the disks of virtual machines on my desktop computer, and a small case so as to allow me to mobilize the laboratory where a customer or any talk.

I’ve put together this combo for $229.20, even though the case does not seem small enough, I’d like one type iStarUSA D-118-ITX/1U180FX1 1U mini-ITX Rackmount, but this does not work for a micro-ATX motherboard:

WebCam working with Java, jLabel, swing, opencv and javacv

by Edwind Richzendy Contreras Soto on Monday June 24th, 2013

These days I’ve been experimenting with java (though I’ve always tried to avoid it) due to a client request for a development project.

Java development tools are not entirely ugly as I thought, in fact I found it very productive to develop here, quickly made a desktop application that connected to MySQL to query and save records in a couple of days, But my problem started when trying to run the webcam, I thought that a language like java could have many ways to do this and I was right, but many things are outdated or do not work, for example it seemed logical to use the gstreamer project and the java bridge, but the project is outdated since 2011.

After many tests,  I have good results using the library opencv, I know, using opencv to handle a webcam is a very simple operation for all the things that makes this library however was where I could get everything working well I thought it easier to implement that would allow me to operate the same in Windows or mac OSX with just installing opencv on that platform (java is really multiplatform?).

I made a demo code and NetBeans project using pieces of code I found on the Internet and making it work as wanted in a swing frame displaying the video on a JLabel and also lets you shoot video with the push of a button, the code can be downloaded here:

[Info] SwingWebCam.tar.gz [/ info]

To run the code must have opencv installed (available from the official repositories of any linux distribution) and you must load javacv .jar files too to library project path in to Netbeans, don’t worry much about the jar, the code show errors in to Netbeans if you  not load the .jar files, this files are needed to you can run the project without errors.

I hope they can help, any doubt please use the comments, otherwise this code is not meant to be more than it is (a demo), so any improvement is welcome but do not think that will be implemented directly in the code.

GNU/Linux World Map

In the GNU/Linux world as if they were one large region Fabian Inostroza Oyarzún designer shows us how would geopolitical division of the world in which the kingdoms consist of large distributions and applications GNU/Linux.
