Forwarding of the so-called ‘funny’ mail isn’t funny anymore!

Screenshot-2Everyone knows them. The so-called ‘funny’ mails.
Most of the time they contain a hoax, a big-ass picture, a power-point presentation or a video clip.
On top of this, they usually also contain a huge list of mail-addresses from people you don’t even know.

By this post, I’d like to point out that not all people like these mails unlike what some people tend to think.
Consider that there are people that get a lot of serious mail. (yes, it can be used in such manner)
You might not be aware of it, but reading all those mails take an huge amount of time.
These people are constantly fighting against unwanted messages as it consumes way too much time.
This is not such a big deal, but it gets harder if their mail-address is being used in a inappropriate way.

By inappropriate I mean that their mail-address, along with a lot of other addresses, is put inside the ‘cc:’ field, making it visible to all people ever receiving that mail.
If you’re not aware of the implications, just imagine that your home address or your cell-number is published instead of your mail address.
Some people use this medium for work related communications or for serious business. The so funny mails become quite annoying in this context.
In the end, they are unwanted messages, also called spam.

I understand that you might want to share the funny stuff with people you know.
But take some actions to prevent spamming people.

Things you can do

  • Use the BCC: field to place the mail-addresses in.
    This will prevent you from distributing people’s address to the world.
    You can do this in Outlook .
  • Think twice when forwarding a mail to your contacts.
    Differentiate people that use the mail-system for social contacts and those that use it for serious business.
    You can do this by making distribution listsin Outlook or Windows Live (alias hotmail), categorizing these people.
    This makes it also faster and easier to send the mails.
  • If someone answers your mail asking you to stop sending this kind of mails, don’t ignore it.
    That person will possibly just block all your mails, resulting in the ignorance of serious mails.

For an overview of the email etiquette you can check out this website for a nice and comprehensive list of things you should know before using any mail-system.

One keyboard and mouse for multiple computers running Ubuntu

When you have multiple computers on your desk, it can be very annoying to switch keyboard an mouse each time you want to do something on one of the other computers.
So, you can solve this by just using one keyboard and one mouse for multiple computers without buying a hardware switch.
Synergy is a package, available from the repository that lets you share the mouse and keyboard over a range of different computers.
When synergy is active, your keystrokes will be send to the machine where your cursor is currently positioned.
The cursor will slide from screen to screen just as if you are working on one single system with multiple screens attached.
As far as I know, it’s not possible to drag windows from one machine to another. Which would be nice.
So if you’re a programmer and you’re still searching for a useful project, then this is just your bit.

Here is how you can easily start sharing your keyboard and mouse between different computers and screens using synergy on Ubuntu:

First off, install the synergy package and the QuickSynergy packages on each machine you want to use your pointer on with the command:

sudo apt-get install quicksynergy

Note that apt will install the synergy package as it’s required to run QuickSynergy. (QuickSynergy is in fact just a gui for Synergy)
When it’s installed, you’ll find QuickSynergy under the category ‘accessories’ in the application menu.

On the server:

The server is the computer where the used keyboard and mouse are attached to.
In the Share tab fill in the names of the computers where you want your keyboard and mouse to be operational.
Do not fill in the IP address, it won’t work.

Synergy server

To find out the name of your computer(s), open a terminal and type:


If all the hostnames are put in the right place, start the service by clicking ‘Execute’
Note that the window becomes gray.
You can now just minimize it and let it do it’s work.

On the client:

On the Client, fire up the QuickSynergy app and go to the Use tab.
Fill in the hostname of the server.
Note that you can also enter its IP, but know that when you’re using dynamic IP adresses, you’ll have to reconfigure this each time you fire up Synergy.

Synergy Client

Then just hit execute and minimize the window.
Now you can remove your keyboard and mouse from this computer.

When moving the mouse outside the window to the side you’ve configured the other computers position on the server, you’ll see your pointer go ‘troug’ the space between the two computers and appear on the other screen.
Als handy to know is that the clipboard is shared.
So you can actually copy something on machine 1 and paste it on machine 2. (text that is, don’t try this with data)

Synergy uses an unencrypted TCP/IP stream on port 24800. So if you’re on a network you can’t entirely trust, don’t use it unless you encrypt it.
I would even recommend ALL users using a wifi-network to encrypt the connection.
To Encrypt the Synergy data, you can simply follow the guide on their website.

Ubuntu-be on the Dipro Mega Market Ghent

Ubuntu-be will, as usual, be present at the next Dipro Mega Market event in Ghent.
Just like previous years, we’ll not only hand out free Ubuntu cd’s, but we’re also going to give advice and demo’s on how to use the most common applications.
Are you thinking about trying Ubuntu, but you don’t know how to start? Just come visit us.
We’ll give you the tips and help to get started.

But you could also just come by to say hi too of course. 🙂

New screen

Today, I bought my second 22″ Widescreen (Medion) monitor for only €150.
With its maximum resolution of 1680×1050, contrast of 1000:1 and a 5 ms reaction speed, it makes just a simple yet perfect addition to my desk.
This is one of the devices that just does the trick.
If I had spend 35 Euro more, I could have bought a Full-HD 23″ monitor from samsung… but I just can’t find a purpose for the Full-HD function and the 23″ would denigrate my other (also a 22″) screen.
It’s main purpose will be browsing, coding and a little bit gaming or designing.

I’m proud to present, my new screen (middle) functioning as a second screen for my portable (Dell Latitude D820).


I had to disable Compis Fusion on my laptop so that I could disable screen monitoring on the dual-head.

Ubuntu Server on VirtualBox returns error This kernel requires the following features not present on the cpu: 0:6

I installed Ubuntu Server 8.04 inside a VirtualBox (v 2.4.1_OSE) virtual machine.
The installation went smooth, but when I wanted to boot into my Ubuntu Server, it returned the following error right after GRUB:

This kernel requires the following features not present on the cpu: 0:6
Unable to boot – please use a kernel appropriate for your CPU

Screenshot or it didn’t happen?

Ubuntu Server on VirtualBox returns error

How to solve:

This can be easily resolved by enabling the PAE/NX option in the virtual machine’s settings.
This will expose the PAE of your CPU to the virtual machine.


  1. go to the homescreen of Virtualbox
  2. select your virtual machine
  3. click the ‘settings’ button on top of the screen
  4. click the tab ‘Advanced’
  5. check the box next to ‘PAE/NX’

Like in this screenshot:

Now, you can fire up your virtual machine again, and it will start up without this error.

Are Linux users more Cat people than Windows users?

While browsing the internet for the past years, I’ve encountered quite a lot of websites around cats.
Some are even single service sites, such as icanhascheezburger,lolcats, etc…
So cats are, according to me, more popular than any other animal within the internet community. Even if google disagrees.

The cat

Language ‘problems’ inside an Ubuntu LUG

belgiumAs you may know, Belgium has 3 native languages: French, German and Dutch.
Lately, people tend to make a big fuzz about this.
Political party’s started creating diversity based on these languages to use this in their own advantage (votes).
The media has added its share to this too.

I personally don’t mind all these easy and low ways of getting attention.
But now the discussion has appeared as a burden inside our Ubuntu-be LUG as well.

The guys from Gentoo did it again!

Lots of hardcore hackers use Gentoo as their favourite distribution.
Mind to interpret hackers in the correct way!
This results in the a very strong technical support base, lots of nice tweaks and awesome hacks.
Sometimes the hacks they release are quite nuts.

What did you think of using the RAM on your Graphics card as swap space or RAM disk?
I wonder how this guy got this idea.
I cant think of a decent purpose for this.
Doesn’t matter… this hack is awesome!

Ubuntu-be update

Due to inactivity the last month on the Ubuntu-be mailing list, I had some catching up to do on the huge list of unread mails.
Amongst them I found this mail from  Pierre Buyle:


for those requesting a Forum for Ubuntu-be, there is an alternative
solution (which has already been discussed in the past). Gmane
provides two web interfaces for our mailing list. A blog-like one at and a threaded
one at

In addition, I registered the mailing list for archiving on Nabble
which also provides an forum like web interface at

These three interface allow one to follow activities on the mailing
list without dealing with it as a bunch of mail. Both Gmane and Nabble
allow posting to the list through the Web interface (only for
subscribed user registered there).

So, if you’re interested in following the Ubuntu-be mailing list, you can easily do so without the ‘hassle’ of subscribing to it.
It’s also a perfect way to check it out for a while, as you don’t receive all these mails in your mailbox.

I have to say, it’s the first time I’ve seen the integrated nabble forum in action, and have to agree that it’s awesome.
Also the blog-styled layout of gmane is making the mailing list (more) enjoyable to read.

Of course, you can also just send a mail to the ubuntu-be mailing list.
Warning: This is a public medium! If you want to send messages to this list you’ll have to register first through Keep into consideration that every message posted will be visible in the public archives!

LFS 6.5 Released

The new LFS 6.5 is released.
Although I never tried it, it’s intriguing me (a lot).
Not just because it’s a geeky thing to do, but because it’s the best way to understand how linux works.
To erase all confusion here,LFS is not a distribution, it’s a guide.
A 314 pages (and counting) book written by Gerard Beekmans.

I tried a number of distributions and could not decide on any one. They were great systems in their own right. It
wasn’t a matter of right and wrong anymore. It had become a matter of personal taste. With all that choice available,
it became apparent that there would not be a single system that would be perfect for me. So I set out to create my
own Linux system that would fully conform to my personal preferences.
To truly make it my own system, I resolved to compile everything from source code instead of using pre-compiled binary packages.

Whenever I have some spare time…
But for now, I’m quite happy with my Ubuntu.
