Tutorial: Create an NFS-like Storage Server with GlusterFS on Ubuntu 12.10

vote

This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA. read more...

Build Apps with Android SDK, Eclipse, PhoneGap (Ubuntu 10.10)

vote

This tutorial describes how you can set up a development environment for building Android apps on an Ubuntu 10.10 desktop using Eclipse, the Android SDK, and PhoneGap. I will describe how to build Android apps from the command line with PhoneGap and from the GUI with Eclipse and PhoneGap and how to test them in an Android emulator and on a real Android device. PhoneGap allows you to develop your Android applications using web technologies such as HTML, CSS, and JavaScript (e.g. with JavaScript libraries such as jQuery/jQTouch), and it will turn these web apps into native Android apps (in fact, PhoneGap supports multiple platforms such as Android, iPhone, Palm, Windows Mobile, Symbian, so you can use the same sources to create apps for multiple platforms). read more...

Ubuntu 12.04 LAMP Server Setup

vote

In around 15 minutes, the time it takes to install Ubuntu Server Edition, you can have a LAMP (Linux, Apache, MySQL and PHP) server up and ready to go. This feature, exclusive to Ubuntu Server Edition, is available at the time of installation. The LAMP option means you don’t have to install and integrate each of the four separate LAMP components, a process which can take hours and requires someone who is skilled in the installation and configuration of the individual applications. Instead, you get increased security, reduced time-to-install, and reduced risk of misconfiguration, all of which results in a lower cost of ownership. Currently this installation provide PostgreSQL database, Mail Server, Open SSH Server, Samba File Server, Print Server, Tomcat Java Server, Virtual Machine Host, Manual Package selection, LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations. read more...

High-resolution text console with uvesafb in Debian/Ubuntu

vote

While you may rarely use the console on your server, it's nice to have a high-resolution display just to see that many more columns and rows. Linux's vesa module (via the vga= parameter) has been around for a while and made this possible, provided you kept up with what VGA mode number to use and don't mind the spotty hardware compatibility.

While KMS is the way to do this in the future, it doesn't help us with the drivers and hardware we have now. A new kernel module, uvesafb, mainlined in 2.6.24, is another, new option. In addition to specifying modes in a more user-friendly way (i.e. 1280x1024-32 for 32-bit color, with a 1280x1024 resolution), hardware compatibility is better in particular, you can now get a high-resolution text console with NVIDIA display adapters.

In the following, I describe how to use uvesafb on Debian and derivative distributions (i.e. Ubuntu). The instructions assume kernel 2.6.27 or higher.

(and here's a bit of high resolution digital art) read more...

ATA over Ethernet (AoE) (Ubuntu 12.04)

vote

This guide explains how you can set up an AoE target and an AoE initiator (client), both running Ubuntu 12.04. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive. read more...

Ubuntu is not a community distribution

What most people fail to realize is this: Ubuntu is a suite of operating systems (Desktop, Server, Cloud, and Touch) sponsored by a company called Canonical Ltd. And Canonical is a commercial entity with employees, paid employees. As such, any decision taken by its management is taken with the commercial interest of the company front and center. read more...
