Linux Mint 10 vs. Ubuntu 10.10

Discover why I prefer Linux-Mint Julia over Ubuntu Maverick...
Yet, default [Ubuntu] functionalities are not enough to turn a Windows-7-addicted into the Ubuntu lover I want him to become. In fact, Ubuntu new-comers get shocked by the new interface gnome offers, and frustrated when they find no flash support for their browsing. Hence, in order to fill that gap, I find myself downloading, installing and configuring new features, like compiz for visual effects, closed-source codecs for medias, system upgrades for more stability, a more friendly theme, etc...

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...

Tutorial: Android app build environment with Eclipse, PhoneGap (Ubuntu 11.04)

Up
vote
Down

This tutorial describes how you can set up an development environment for building Android apps on an Ubuntu 11.04 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...

Icinga is an enterprise grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. Scalable and extensible, Icinga can monitor complex, large environments across dispersed locations.

Icinga is a fork of Nagios and is backward compatible. So, Nagios configurations, plugins and addons can all be used with Icinga. Though Icinga retains all the existing features of its predecessor, it builds on them to add many long awaited patches and features requested by the user community. read more...

How to install Ubuntu Linux on the decTOP SFF computer

Up
vote
Down

I recently bought a decTOP small form factor (SFF) computer. My goal was to build a cheap, fanless, quiet, and low power consumption Linux server. For $99 plus the cheapest available shipping, $40, my machine arrived 11 days after I placed the order.

This is a tiny computer, about the size of a Mac Mini. But, because it has no fan, it runs a bit quieter and, with the help of a 1-watt, 366 MHz CPU, consumes only 8 watts. For comparison, the G4 Mac Mini consumes about 20-30 watts, depending on load.

The decTOP comes with 128 MB of RAM in its sole SO-DIMM slot and a 10 GB 3.5 inch hard drive. I understand that it's a simple matter to replace the drive and to upgrade the memory to a maximum of 512MB.

It also comes with no operating system and the ability to boot only from a USB drive. This article details the steps I used to build the USB boot/installation drive and install Ubuntu 6.06 on the decTOP.

There is another article -- with additional decTOP links -- here on installing Ubuntu 6.06 on the decTOP with the aid of a Windows system. Fortunately ;), I run Mac OS X and Linux (Ubuntu 7.04), so that article didn't work for me. I did the installation of the Ubuntu 6.06 LTS Server Edition using my Ubuntu Linux box and a 1 GB USB flash drive -- although a 512 MB USB drive should work as well.

  1. Download the Ubuntu 6.06 server ISO image from the Ubuntu download page. Depending on your plans for the decTOP, you might want to choose the desktop version. Unless you have already upgraded your decTOP's memory, however, you'll want to stick with the 6.06 releases.

  2. Install the mbr, mtools, and syslinux packages on the Linux system you'll be using to prepare the USB drive. If you run Ubuntu or some other Debian-derived system, the following commands may do the work for you.
    apt-get install mbr
    apt-get install mtools
    apt-get install syslinux
  3. Partition the USB drive with a single FAT-16 partition. I used the fdisk 'n' command to make the new primary partition 1. The fdisk 't' command can be used to change the partition type to FAT-16. My device name was /dev/sda.
    fdisk /dev/sda
  4. Make the FAT-16 partition the active partition. I used the fdisk 'a' command.

  5. Install a master boot record on the USB drive.
    install-mbr /dev/sda
  6. Install syslinux on the USB drive. Note that the USB drive should not be mounted when you do this.
    syslinux -s /dev/sda1
  7. Create a mountpoint and mount the ubuntu ISO image using the loopback device.
    mkdir /iso
    mount -o loop -t iso9660 ubuntu.iso /iso
  8. Create a mountpoint and mount the USB flash drive.
    mkdir /usb
    mount /dev/sda1 /usb
  9. Copy the contents of the ISO image to the USB drive. This will take some time.
    cd /iso
    cp -r . /usb/
  10. Copy the /usb/dists/dapper directory into a new /usb/dists/stable directory.
    cd /usb/dists/
    cp -r dapper/* stable
  11. Copy several files from /usb/install to the /usb root directory.
    cp /usb/install/vmlinuz /usb/
    cp /usb/install/mt86plus /usb/
    cp /usb/install/initrd.gz /usb/
  12. Install the following text into a file named syslinux.cfg in the /usb root directory.
    default vmlinuz
    append initrd=initrd.gz ramdisk_size=24000 root=/dev/ram rw
  13. Flush all writes, unmount, and remove the USB drive. After the sync step, wait for all of the data to be written to the USB drive.
    sync;sync
    umount /usb
  14. Connect the ethernet adapter to the decTOP and connect it to your network to allow automatic configuration of the network interface.

  15. Insert the USB drive into the decTOP and power it up. The decTOP should automatically boot from the USB drive and start the Ubuntu installation.

  16. Answer only the first two questions concerning language selection and go to the next step, below.

  17. Press Alt-F2 (hold down the Alt key and press the F2 function key) to open a shell. Then press enter to start the shell.

  18. Create a /cdrom and a /dev/cdroms directory in the installation ramdisk
    mkdir /cdrom /dev/cdroms
  19. Go to the /dev/cdroms directory and build a symlink from /dev/sda1 (that is likely the device name of your USB boot partition) to /dev/cdroms/cdrom0.
    cd /dev/cdroms
    ln -s ../sda1/cdrom0
  20. While still in the shell, mount the USB drive to mimic an installation CD-ROM.
    mount -t vfat /dev/cdroms/cdrom0 /cdrom
  21. Return to the installation program with Alt-F1 and continue the installation.

From this point, the process should be identical to a routine CD-ROM installation.

For a grand total of $140 and 8 watts of power consumption, I now have a near-silent Linux server running 24/7. You can telnet to it here and marvel at its blinding speed running a 250,000-sector Space Tyrant game.

High-resolution text console with uvesafb in Debian/Ubuntu

Up
vote
Down

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.
