Re-purpose ancient hardware - part 1

An ancient Compaq Evo N115 is still working, however the concern is how: AMD Duron 1.2GHz processor, 64KB cache, 384MB RAM, 20GB hard drive, 13.3" 1024x768 TFT display ... manufactured some 10 years ago!

After some googling, I landed on the Webconverger page
 The 450MB ISO image can either go to a USB stick or be burned to a CD; the boot is rather fast and takes you to the Webconverger registration page via the Iceweasel browser.
The concerned notebook is equipped with a RJ45 Ethernet jack, but the aim is to have it working on Wi-Fi by the means of a Netgear PC Card; unfortunately Webconverger does not seem to give the chance to personalise that much your setup.
The card works well with MS Windows drivers; my copies are stored here.
There is Puppy Linux derivative named BrowserLinux, a 93MB only Linux distribution, current version is 501.
There is an install-to-disk feature, but it has failed :( thus I keep the boot-from-CD coupled with the save-session feature; the latter saves a file on the hard drive (light encryption, at least, is recommended). Three re-boots are needed to have everything working: Firefox profile sync, Wi-Fi drivers working (download and save them somewhere in the hard disk, e.g. /mnt/home/home), Wi-Fi key stored. The re-purposed box boot is rather fast, navigation and (ordinary) page rendering are smooth, although Firefox version is 5.0.1 only.

Testing of some builds from susestudio are under way...

Conky and OpenSUSE (11.3) on a Plasma desktop


Conky is a terribly light system monitor for X
Apart from its home, a good starting page is this one, and a helpful tutorial on how to arrange it on your desktop is here, though some further tricks are needed to have it working on your Plasma desktop enjoying transparencies (I surfed a while throughout the Web, so I regret I cannot mention all the pages, well not that many, I took hints from).

With OpenSUSE there is no need to hunt for the right package, download and install it, just open Yast2, type 'conky' and check it for installation.
Then copy the conky.conf file in /etc/conky/ to your home as .conkyrc and start editing it.

Initiate from the settings suggested in this page, but be sure to make these further changes in order to have conky stuck on your desktop, transparent and below all other windows
own_window yes
own_window_class conky-semi
own_window_type desktop
own_window_argb_visual yes 
particularly, the last one.

To have your Google Calendar within Conky, install gcalcli from Yast2; the gcalcli how-to wiki page is here.

More work is needed if you want also some weather information through the ConkyForecast python script.
  1. Download the tarball from here;
  2. Unpack it somewhere;
  3. Rename its src folder as conkyforecast and give running permissions (755) to the conkyForecast script;
  4. Copy conkyForecast.config to your home as .conkyForecast.config;
  5. Now you need root privileges to move the conkyforecast folder to /usr/share/.
 If your desktop is set to wallpaper slideshow, it would be smart to set shades to improve readability
default_outline_color white
default_shade_color black
draw_shades yes
What is still uncomfortable is enabling / disabling and external display during a session (I do it quite frequently): Conky runs in a window and as such is managed, therefore it could requires to kill Conky and restart it.

Whether you want to share the monitor with more computers, move .conkyrc, .conkyForecast.config, and .gcalclirc somewhere in your Dropbox account (remember to link them back in your home).

I have a Linux Mint box to test it, therefore I followed literally the Ubuntu steps for installation:
  1. sudo apt-get install conky
  2. gksu gedit /etc/apt/sources.list 
    1. where the line deb http://ppa.launchpad.net/m-buck/ubuntu hardy main has been added;
  3. sudo apt-get update
  4. sudo apt-get install conkyemail conkyforecast
  5. sudo apt-get gcalcli
Once all the software is on-board, link .conkyrc, .conkyForecast.config, and .gcalclirc from the Dropbox folder to the home, and it works.

openSUSE 11.3 live on netbook

Live image can be downloaded from here both for 32 and 64 bit platforms.
The downloaded image can be burn on a CD or on a USB-stick; in case of the latter, the following command line does the job
dd if=openSUSE-11.3-KDE4-LiveCD-arch.iso of=/dev/sdX
where arch (either i686 or x86_64) is the chosen architecture and X the letter identifying the device (unmounted).

I've tested it on a Samsung NC10 - 2GB; the boot takes a little while (about 3 to 4 mins); the 1024x600 size is properly set, though the so-called form factor is not set within the system settings.

Also the touchpad needs some personalisation (as well as on systems installed from the 'main' DVD), at least to enable tapping.

All settings are saved by default (personalisation, desktop properties, passwords, WPA keys, ...)!

Unfortunately, some dialogs can hang X, and CTRL-ALT-BACKPACE hangs the system.
After some tries (i.e. reboots) system hangs become so frequent to make further tests a waste of time.

openSUSE 11.3 and multimeda format

Since different copyright apply according to different countries, several formats that cannot be included on the openSUSE ISO because they're proprietary, patented formats.

Such restricted formats can be found on this page and installed one-click:
A successful installation allows you to see tv broadcasting services
(DVB, BBC World)
as well as DVDs
(Animatrix)

    Ubuntu night-time display

    Redshift is a charming application for Ubuntu to make your Linux-box display much more comfortable at night-time.

    Full installation instructions can be found here.

    The only regret is the lack of a GUI interface for tool setting; however command-line is very easy.

    Dropbox and OpenSUSE (11.1)

    Dropbox officially reports to support Ubuntu and Fedora, while other Linux could (generally) work.

    From the OpenSUSE repository, I've installed dropbox-cli, then run the installed software, that warns me to download the proprietary daemon.

    Once the donwload is completed, a dialog (like the Windows one) appears driving you through the usual procedure.

    When the sync starts, you get the dropbox icon in your tray and a Nautilus window on your desktop (one more file browser :( - however, dolphin works as well), and, of course, your linux-box is properly identified in your dropbox account.
