Ubuntu, Serial port, Bluetooth console, Nokia E61i, Python

23 01 2009

A while back, in this post here, i described how to access the Bluetooth console through Bluetooth from a Nokia E61i to Win XP.

After that i’ve been meaning for a long time to write about the same procedure, but running Ubuntu now as an operating system.

First we need to install Python for Symbian (pys60). The .sisx file can be found on the project’s SourceForge page here.

Hardware used:
Dikom Bluetooth Usb Dongle : 00:02:72:XX:XX:XX
Nokia E61i : 00:17:E5:XX:XX:XX
Dell Dimension C521 running Ubuntu Intrepid Ibex (8.10)

Dual Screen Ubuntu – Windows XP with Synergy

21 10 2008

Truly, i cannot believe i had missed this piece of software up until a few weeks ago.
Here’s the description from the official page:

Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s).

Says it all, and was exactly what i was looking for.

Synergy works with a client server architecture. The box that i mainly use, runs Ubuntu 8.04, and i will be using this one as a server. The other machine, that i want to share the input devices with , is my laptop, that i will be booting into Windows XP. This one will be the server.

Remotely monitoring MySql databases with Mytop and Terminator

21 10 2008

When finding yourself maintaining Mysql servers within a cluster, network, or even further spread out, it becomes very handy, for monitoring purposes, to take a peak at the activities of Mysql.

A very useful little tool that helps doing this, is MyTop

mytop is a console-based (non-gui) tool for monitoring the threads and overall performance of a MySQL 3.22.x, 3.23.x, and 4.x server. It runs on most Unix systems (including Mac OS X) which have Perl, DBI, and Term::ReadKey installed. And with Term::ANSIColor installed you even get color. If you install Time::HiRes, you’ll get good real-time queries/second stats. As of version 0.7, it even runs on Windows (somewhat).

The source can be found on the official page. For ubuntu, the package is in the repositories, and this is the case we’ll be talking about.

Installing Openproj on Ubuntu

10 10 2008


I was looking for a new application to use for project management. Amongst people that i spoke to, and e few web resources OpenProj seemed to be quite a must.

OpenProj by Serena Software is a desktop replacement of Microsoft Project. OpenProj has equivalent functionality, a familiar user interface and even opens existing MSProject files. OpenProj is inter operable with Project, with a Gantt Chart and PERT chart

sourceForge page

Seems to be pretty handy. On it’s SourceForge page though there’s only a .rpm noarch package.
The RPM packet manager is available for Debian-based systems indeed, non the less there are a few complications.

When attempting to install openproj with rpm:

sid@dev:~/Desktop$ rpm -i openproj-1.4-2.noarch.rpm
rpm: To install rpm packages on Debian systems, use alien. See README.Debian.
error: cannot open Packages index using db3 - No such file or directory (2)
error: cannot open Packages database in /var/lib/rpm

What’s alien?

Alien allows you to convert LSB, Red Hat, Stampede and Slackware Packages into Debian packages, which can be installed with dpkg.
It can also generate packages of any of the other formats.
This is a tool only suitable for binary packages.

Here goes the installation from the Ubuntu repositories:

sudo apt-get install alien

Afterwards it’s time to convert Openproj from a .rpm package to a .deb one.

sudo alien openproj-1.4-2.noarch.rpm openproj-1.4-2.noarch.deb

Once the package is created, double click on it, to install with the gDebi installer.

Been using it for a few days now, and i must say, i regret not having picked it up earlier.





Java support and latest Flash for Konqueror on Amd64

10 10 2008

A few days ago i installed Konqueror on a Ubuntu 64bit machine, upon request.

The installation went smooth (why not?). The issue came up while attempting to get Flash and Java to work.
The workaround was fairly simple.

Java
After installing Java, the trick is done by giving Konqueror the absolute path of the executable:

Konqueror -> Settings ->Configure Konqueror -> Java & Javascript

and set (in my case) to /usr/bin/java

Flash

Open a shell window and type:
sudo apt-get install konqueror-nsplugins flashplugin-nonfree

Konqueror -> Settings ->Configure Konqueror -> Plugins.->Scan for new plugins

Restart Konqueror.





Enabling Desktop Effects for Ati Radeon Xpress 200M on Ubuntu Hardy Heron

10 08 2008

To make sure that this is the model of your graphics card, on a terminal window and type:

lspci | grep -i vga

The output should be similar to this :

01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE)

Now we need to install the fglrx driver:

sudo apt-get install xorg-driver-fglrx

Enable the Ati driver from the System -> Administration -> Hardware Drivers.

Reboot the system, open a terminal window and type:

fglrxinfo

The output should be the following:

display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress Series
OpenGL version string: 2.1.7412 Release

That’s it.





Hardy On Acer Aspire 3680

9 08 2008

Today did an installation of Ubuntu 8.04 on an Acer Aspire 3680, which up until this point was used as a Windows machine.

Turns out this model too has the Atheros AR5007EG (AR242x ) installed.
The same as the Aspire 5315.

In previous post i had described a fix for this card using ndiswrapper.
The same instructions are valid this time too.

Here’s the link : /hardy-on-acer-aspire-5315/
