Extend a LVM partition after increasing its virtual disk on Virtualbox

No Linux machine at work? the easy way could be to simply install Virtualbox in one of the PC, create a VDI and install Ubuntu 14.04 in it. But the day will come when you need more space!

And this is a website to convert Gb into Mb (–resize takes Mb as input, 200Gb = 204800Mb). Boot Gparted to resize the partition After a default install of Ubuntu Server on one physical disk, you will have a SWAP partition, and then an extended partition in which you’ll have your LVM partition (So 3 partitions).

Website Using HTTPS Protocol

Last week, I changed protocol of my website from http to https. There were steps that i had to do. First, I installed openssl package and mod_ssl # yum install mod_ssl openssl Then, I configured the openssl and created certificate # cd /etc/pki/tls/certs # make server.key # openssl rsa -in server.key -out server.key # make server.csr # openssl x509 -in server.csr -out server.crt -req -signkey server.key -days 3650 # chmod 400 server.* After that, I changed configuration of httpd/apache #nano /etc/httpd/conf.d/ssl.conf DocumentRoot "/var/www/html" ServerName www.server.world:443 SSLCertificateFile /etc/pki/tls/certs/server.crt SSLCertificateKeyFile /etc/pki/tls/certs/server.key Last, I restarted the webserver #service httpd restart That's all what i did last week to change my website protocol from http to https.

DirectX Standard Multimedia Development on Windows

In the past, game programmers create their own plot between device and the software. Because Computer Architecture is complicated, so it hard to obtain the desired speed for real animation, manufactures of sound cards and display adapter had to write drive for various display adaptor, it made the development of game is really hard. And if you know, most computer games were written for MS-DOS. Maybe you remember game Mario Bross, F1, Prince of Persia and others. Then Microsoft released MS Windows, so the game developer made game for its OS. And for the easier of programmer made their game, Microsoft give an idea that made programmer can make a standard plot to connect with hardware. This idea introduce in 1995 and at last it become a standard for develop multimedia on Windows platform named DirectX.
