On 10th of April 1976 in 20:34 mins Moscow time from Boikonur Cosmodrome was launched s spaceship "Souyz-33 / Union-33" . On spacecraft flies 3 cosmonauts part of the space program Inter-cosmos, one of which is the Bulgarian cosmonaut and explorer Georgi Ivanov. Georgi Ivanov became the first Bulgarian who the leave planet earth, becoming the first space visitor with Bulgarian nationality.


Ivanov spend in space 1 day 23 hours and 1 minute, after that the capsule landed in 320 km south-easy from Jezkazgan (Khazakhstan).
For his short stay in space in Earth's orbit Ivanov made 31 full turns around Planet Earth. With his flight to space Bulgaria joined the elite club of  "austranaut nations", making Bulgaria the sixth nation in world who sent representative in space.


Flight mission's goal was linkage of their spaceship with orbital station "Salute-6" but because of technical malfunction "Syiuz 33"s moving with higher than forecasted and speed autoamtic correction system turns on which damages part of fuel camera, making necessary to cancel the flight.


Returning home on Earth he was awarded with medals "Hero of the USSR" and "Hero of Republic Bulgaria"
Nevertheless the mission was unsuccesful and dangerous Ivanov's pulse during all flight kept normal.

Georgi Ivanov is born in Lovech on 2-nd of July 1940 in family of Anastasia Kakalova and Ivan Ivanov Kakalov.During his school years he excercised parachutism, graduating in high-school "Todor Kirkov" Lovech in 1958.

Ivanov entered Bulgarian army in 1958 graduated Military school in Dolna Mitropolia (1964) with specialty of flight engineer and a pilot of class 1.
He served in Bulgarian National Army as a pilot, senior pilot, commander  and a squadron commander. In 1984 he defended his thesis and received a science degree "candidate of physics sciences". Georgi Ivanov is currently 73 years old. Nowadays Ivanov's birthouse in qr. "Varosha" is of historical importance and is preserved as a museum.

The fact that we Bulgarians have a cosmonaut is a great pride for me and all of us Bulgarians. Let us not forget our heroes and patriots and know our history.

Debian (Unstable) Squeeze / Sid /usr/lib32/alsa-lib/ linked to missing libraries

While playing with my installed programs on my recently updated Debian I stepped into a problem with /usr/lib32/alsa-lib/ It seems the library was linked to two non-existing libraries: /emul/ia32-linux/lib/ as well as /emul/ia32-linux/usr/lib/ A temporary solution to the issue is pointed out in Debian of the Debian Bug reports . As the report reads to solve that it’s required to:

1. Download libwrap0_7.6.q-18_i386.deb and libgdbm3_1.8.3-6+b1_i386.deb.

2. Extract the packages:dpkg -X libwrap0_7.6.q-18_i386.deb /emul/ia32-linux/dpkg -X libgdbm3_1.8.3-6+b1_i386.deb /emul/ia32-linux/

3. echo /emul/ia32-linux/lib >> /etc/

4. Execute /sbin/ldconfig

5. Check if all is properly linkedExecute ldd /usr/lib32/alsa-lib/|grep -i “not found”Hopefully all should be fixed now.

How to fix Pulseaudio and Skype crappy sound glitches, choppy sound and crackling on Debian GNU / Linux

Tuesday, January 10th, 2012

I've experienced plenty of problems with Pulseaudio and Skype output sound hell crappy. This stupid proprietary program Skype is a total crap … Anyways again thanks to ArchLinux's wiki, I've used the two mentioned steps to fix all this Skype in / out problems …

1. Fix problems with Glitches, voice skips and crackling In file /etc/pulse/ its necessery to substitute the line;

load-module module-udev-detect


load-module module-udev-detect tsched=0

2. Resolve Choppy sound in (Pulseaudio) -> Skype

In /etc/pulse/daemon.conf two lines has to be also substituted:

; default-sample-rate = 44100

Should become;

default-sample-rate = 48000

3. Change /etc/default/pulseaudio to allow dynamic module loading

It is a good idea to the default settings from DISALLOW_MODULE_LOADING=1 to DISALLOW_MODULE_LOADING=0 .This step is not required and I'm not sure if it has some influence on solving sound in / out problems with Skype but I believe it can be helpful in some cases..

So in /etc/default/pulseaudio Substitute:




4. Restart PulseAudio server

After the line is changed and substituted a restart of PulseAudio is required. For PulseAudio server restart a gnome session logout is necessery. Just LogOff logged Gnome user and issue cmd:

debian:~# pkill pulseaudio

This will kill any left pulseaudio server previous instances.
