Openmeetings VMWare appliance

I’ve made a VMWare image running Openmeetings, V1.0 RC1, available here

The operating system is Ubuntu 9.04 Server Edition, username administrator, password is password. The same username and password was used for the Openmeetings login. MySQL root password is password. All functions are configured, including OpenOffice server for document conversion.

When starting the VM, VMWare will ask if the VM was moved or copied. I suggest to choose ‘moved’, if you choose ‘copied’, VMWare will create a new MAC Address for the network interface and the VM will start with no network interface (it has to be manually reconfigured to match the new MAC Address)

The VM is using DHCP (you will have to execute ifconfig to know its IP address and have a DHCP server running in your network). If you need to configure a fixed IP address you have to manually reconfigure the network interface.

I’m using the VM with version 0.9RC5 for videoconference inside my company and it is working well. The VM with version 1.0RC1 has been less tested, but all the tests made succeeded, so I think you should prefer the V1.0 RC1.

How to produce a drum sound similar to Massive Attack

This kind of drum sound is not very easy to obtain, but here are some tips to try (from the kvraudio forum, posted by soniccouture in 2006)

You don’t need 9 vintage comps to acheive that kind of drum sound. Some thoughts …

1.Use a combination of real and electronic drums. Shorten the decay of real hats and snares to make them sound more electronic. Practice layering real kicks with electronic ones.

2. don’t underestimate the importance of tuning drum samples. This can make a real snare sound slightly synthetic ( in a good way), or tighten up your hats or kick within the rest of the drum pattern. The way they fit together is the key, not the way they sound in isolation.

3. EQ. snap up real snares with lots of 10khz, cut the low end around 200hz. Fizz hats with 8khz.

4. More EG work -once you have your drum pattern going, adjust EG’s of individual sounds so that decays don’t intefere, to give a more intricate, precise sound.

5. Start compressing and limiting. To get the clicky, snappy high end, set a comp ( on the drum group channel) to very short attack – 1ms, and a very short release – 30-40ms. bring down the threshold, bring up the ratio to 4. Hear it get poppy and snappy. back of threshold until its sounds right to you.

5. Now try compressing again, with something more gentle, to squash it all together a bit.

6. Limit. hard. Get the peaks whacking a hard limiter, it’ll flatten and crisp it all up some more.

7. if its still not there, maybe add some EQ after the limiter. be creative, see what works. cut some 1khz, boost some 3, or 8, or 10. birng up 75 hz if kick is a bit thin.

8. Practice this alot. for many years! Being able to make great drum sounds does not happen overnight.
Good luck.

Limiting CD / DVD drive noise

I have an home theater PC based on a NVidia ION motherboard (ZOTAC), and I had a strong noise produced by the DVD drive, because it runs at full speed when it has a disk inside. Using the following command the drive speed is limited to x2, making an acceptable noise for its function.

hdparm -E 2

If you already have the CD/DVD disk in the drive you have to remove it and insert it again in order to enable the drive speed change

Howto make a linux RT Kernel (2.6.31-rc7)

Get the kernel sources and corresponding rt patch (the versions might be different, this was done at the end of August 2008, when the latest rt patch available was for the kernel 2.6.31-rc7, the important thing to consider is to use a patch matching with the kernel source):

sudo apt-get install build-essential
sudo -s
cd /usr/src
chmod 755 *
tar xjfv linux-2.6.31-rc7.tar.bz2
rm linux
ln -s linux-2.6.31-rc7 linux
cd linux
bzip2 -dc /usr/src/patch-2.6.31-rc7-rt8.bz2 | patch -p1 --dry-run
bzip2 -dc /usr/src/patch-2.6.31-rc7-rt8.bz2 | patch -p1
cp /boot/config-`uname -r` .config
make menuconfig

Change the following parameters:

Processor type and features --->
Preemption Mode (Complete Preemption (Real-Time)) --->
( ) No Forced Preemption (Server)
( ) Voluntary Kernel Preemption (Desktop)
( ) Preemptible Kernel (Low-Latency Desktop)
(X) Complete Preemption (Real-Time)
Processor type and features  --->
Timer frequency (1000 HZ) --->
(X) 1000 HZ
 ( ) Staging drivers 

Now build the kernel and install it:

make-kpkg clean
make-kpkg modules_clean
make-kpkg --revision 1 --initrd kernel_image kernel_headers modules_image
cd ..
chmod 755 *
dpkg -i *31-rc7*.deb

To avoid the following error during / after kernel installation:

/etc/kernel/postinst.d/nvidia-common exited with return code 20

I had to execute this command:

sudo apt-get remove –purge nvidia-common

This worked for me because I have no NVidia components on my system (graphic card or chipset).
