Walking in Light With Christ - hip0's personal blog on System Administration, Free Software, Computer Security and Religion

Though, I'm GNU / Linux user for many years now. I have to say, everything is not so perfect as many people present it.
Configuring even simple things related to multimedia on Linux is often a complete nightmare.
An example, today I've decided to upgrade my 32 bit Skype version 2.0 beta for Linux to 64 bit Skype 2.2 beta .
The reason I was motivated to upgrade skype was basicly 2.

a) My Skype run through 32 bit binary emulation with /usr/bin/linux32

b) I had issues with my skype if someone give me a Skype Call, while I have a flash video or some other stream in Browser (let's say Youtube).
Actually being unable to receive a skype call or initiate one while I have some kind of music running in the background or just some kind of Youtube video paused was really annoying. Hence until now, everytime I wanted to speak over skype I had to close all Browser windows or tabs that are using my sound card and then restart my Skype program ....

Just imagine how ridiculous is that especially for a modern Multimedia supporting OS as Linux is. Of course the problems, I've experienced wasn't directly a problem of Linux. The problems are caused by the fact I have to use the not well working proprietary software version of Skype on my Debian GNU / Linux.
I would love to actually boycott Skype as RMS recommends, but unfortunately until now I can't, since many of my friends as well as employers use Skype to connect with me on daily basis.
So in a way I had to migrate to newer version of skype in order to make my Linux experience a bit more desktop like ...

Back to the my skype 2.0 to 2.2. beta upgrade story, the overall Skype upgrade procedure was easy and went smootlhy, setting correct capturing later on however was a crazy task ....
Here is the step by step to follow to make my upgraded skype and internal notebook mic play nice together:

1. Download 64 bit Skype for Debian from skype.com

For the sake of preservation in case it disappears in future, I've made a mirror of skype for debian you can download here
My upgrade example below uses directly the 64 bit Skype 2.2beta binary mirror:

Here are the cmds once can issue if he has to upgrade to 2.2beta straight using my mirrored skype:

debian:~# wget http://pc-freak.net/files/skype-debian_2.2.0.35-1_amd64.deb
...


2. Remove the old version of skype

In my case I have made my previous skype installation using .tar.bz2 archive and not a debian package, however for some testing I also had a version of skype 2.0beta installed as a deb so for the sake of clarity I removed the existing skype deb install:

debian:~# dpkg -r skype
...


3. Install the skype-debian_2.2.0.35-1_amd64.deb downloaded deb

debian:~# dpkg -i skype-debian_2.2.0.35-1_amd64.deb
...


After installing skype, I installed pavucontrol - A volume control for the PulseAudio sound server

4. Install pavucontrol

debian:~# apt-get install pavucontrol




Pavucontrol has plenty of sound configurations and enables the user to change many additional settings which cannot be tuned in alsamixer

pavucontrol was necessery to play with until I managed to make my microphone able to record.

5. Build and install latest Debian (Testing) distribution alsa driver

debian:~# aptitude install module-assistant
debian:~# m-a prepare
debian:~# aptitude -t testing install alsa-source
debian:~# m-a build alsa
debian:~# m-a install alsa
debian:~# rmmod snd_hda_intel snd_pcm snd_timer snd soundcore snd_page_alloc
debian:~# modprobe snd_hda_intel
debian:~# echo 'options snd-hda-intel model=auto' >> /etc/modprobe.d/alsa-base.conf


In my case removing the sound drivers and loading them once again did not worked, so I had to reboot my system before the new compiled alsa sound modules gets loaded ...
The last line echo 'options snd-hda-intel model=auto' ... was necessery for my Thinkpard r61 Intel audio to work out. For some clarity my exact sb model is:

debian:~$ lspci |grep -i audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)


For other notebooks with different sound drivers echo 'options snd-hda-intel model=auto' ... should be omitted.

6. Tune microphone and sound settings in alsamixer

debian:~$ alsamixer



Right after launching alsamixer I had to press F6: Select Sound Card and choose my sound card (0 HDA Intel).

Following my choose I unmuted all the microphones and enabled Microphone Boost as well as did some adjustments to the MIC volume level.



Setting proper MIC Volume levels is absolutely necessery, otherwise there is a constant noise getting out of the speakers ...

7. Use aumix to set some other sound settings

For some unclear reasons, besides alsamixer , I often had to fix stuff in aumix . Honestly I don't understand where exactly aumix fits in the picture with Alsa and my loaded alsa sound blaster module?? If someone can explain I'll be thankful.

Launch aumix to further adjust some sound settings ...

debian:~$ aumix





In above screenshot you see, my current aumix settings which works okay with mic and audio output.

8. Test Microphone the mic is capturing sounds correctly

For the sake of test if my sound settings set in pavucontrol enables the internal mic to capture sound I used two programs:

1. gnome-sound-recorder
2. arecord



gnome-sound-recorder

gnome-sound-recorder is probably used by most GNOME users, though I'm sure Linux noviced did not play with it yet.

arecord is just a simple console based app to capture sound from the microphone. To test if the microphone works I captured a chunk of sounds with cmd:

debian:~$ arecord
Recording WAVE 'cow.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono


Later on I played the file with aplay (part of alsa-utils package in Debian), to check if I'll hear if mic succesfully captured my voice, e.g.:

debian:~$ play cow.wav
cow.wav:
File Size: 22.0k Bit Rate: 64.1k
Encoding: Unsigned PCM
Channels: 1 @ 8-bit
Samplerate: 8000Hz
Replaygain: off
Duration: 00:00:02.75
In:100% 00:00:02.75 [00:00:00.00] Out:22.0k [-=====|=====-] Clip:0
Done.


Finally I launched the new installed version of skype and tested Skype Calls (Mic capturing), with Skype Echo / Sound Test Service
I'll be glad to hear if this small article, helped anybody to fix any skype Linux related issues ?. I would be happy to hear also from people who had similar issues with a different fixes for skype on Linux.
Its also interesting to hear from Ubuntu and other distributions users if following this tutorial had somehow helped in resolving issues with Skype mic.

Earlier I've blogged about how to prevent brute force attacks with fail2ban, denohosts and blockhosts , however there is easier way to secure against basic brute force attacks by not installing or configuring any external programs.
The way I'm talking about uses simple iptables rules to filter out brute force attacks.

Here is a small script to stop ssh and FTP invaders which try to initiate more than 3 consequential connections in 5 minutes time to port 22 or port 23:

SERVER_MAIN_IP='AAA.BBB.CCC.DDD'; /sbin/iptables -N SSH_WHITELIST
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -m recent --name sshbr --set
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -j SSH_WHITELIST
/sbin/iptables -A INPUT -p tcp --dport 22 --syn -m recent --name sshbr \
--update --rttl --hitcount 3 --seconds 300 -j REJECT --reject-with tcp-reset
/sbin/iptables -A SSH_WHITELIST -s $SERVER_MAIN_IP -p tcp --dport 22 --syn -m recent --rttl --remove


The only thin If the rules are matched iptables filter rules will be added to the iptables CHAIN SSH_WHITELIST
In case if you want to add some more truested IPs add some more iptables rules, like:

ALLOW_IP='BBB.CCC.DDD.EEE';
/sbin/iptables -A SSH_WHITELIST -s $ALLOW_IP -p tcp --dport 22 --syn -m recent --rttl --remove


Each filtered IP that matches the rules will be filtered for 5 minutes, if 5 minutes is enough, the 300 value has to be increased.

It is 27th of December, the 3rd day of Christmas and in those day in the Bulgarian Orthodox Church we co-memorate saint Stephen's Martyrdom.

Its a well known fact that by his martyrdom Saint Stephen become the first Christian martyr
Stephen's name etymology comes from Greek (Stephanos) and translated means "Crown".

What we know from Orthodox Church's tradition is that Stephen was a very young in his age of Martyrdom probably in his 20s.

Stephen's glorious martyrdom has inspired and strengthened significantly the early seveerly hunted Church and has give a lot of courage and faith to many of our early Saint Martyrs. These early Church saints now incesently pray to God to have mercy on our earthly Church.
Its not much known fact St. Stephen held a rank in the early Church clergy, he was a HieroDeacon.
Hierodeaconism in our church is considered the maximum rank of deaconship one can have just before he is ordained for a Priest.



St. Stephen was burning for love in Christ and had a strong faith in God, turning many Jewish to our Lord and Saviour Jesus Christ. He has shown the truth way to many by teaching them, how to properly interpret the Old Testament (Ancient Jewish) writtings.
He explained to many jewish, how all the old scriptures testify about the coming of the Messiah (Christ), which will save all who believe in his name from sins hell damnation.
As Jewish looked for ways to shutter any kind of preaching of the Gospel and kill Christianity, they saw Stephen as a big enemy just like all Christians in those early days. Therefore they looked for ways to accuse him and execute them and end up the large numbers of jewish people converting from Jewism to Christianity
The whole story of stoning (execution) of st. Stephen is described in the Holy Scriptures in the book called Acts of the Apostles

As he was about to die, Stephen looked up to heaven and said;

"Behold, I see the heavens opened, and the Son of man standing at the right hand of God."
Then, as he was being stoned, he cried out, "Lord Jesus, receive my spirit.". Our Beloved saints last words were, "Lord, do not hold this sin against them." manifesting his saintship and deep Christ love even during his last moments of earthly living.
St. Stephen is celebrated in almost all West Roman Catholic Church and in Anglicans.
Churches who co-mmemorate the great saint are located in all around the world.
St. Stephen is also considered a patron saint of Republika Sprska (Bosnia and Herzegovina)
Stephen's name later probably become the origin name for western's so popular Steven name).


Let by the Holy Prayers of St. Stephen God have mercy on the Church and increase our faith and mercies to us sinners.

Christ has born! Merry Christmas and Happy Holiday to all my readers!

The meaning of Merry Christmas comes from Christ Mass , the word has changed to (Christmas) through the years.
The origins of the word comes from the western world and especially has a tight relatin with Latin language and the Roman Catholic Church.

In Eastern Orthodox Churches, we say Chestit Rojdestvo Hristovo , which translated to English is Happy Christ's Birth by this tring to put more accent on the real significance of the feast, which is Christ's birth.
It's a pity nowdays many people forgot the real meaning of Merry Christmas but just celebrate without really realizing the deep spiritual meaning this two beautiful words contain.
Our Bulgarian Orthodox Church will mark the Christ's birth with a Holy Liturgy early in Sunday's morning tomorrow 25th of December.

With these bright feast I wish to all my blog readers;
A lot of Best of Health, Good Fortune, Loving Kindness, Hope, Faith, Love and Personal and Professional Success!
May God bring in our hearts the Angels joy which saluted our Saviour Jesus Christ's birth 2011 years ago.

Have a great Christmas!

I just bought an USB Camera (my notebook doesn't include an embedded camera). The camera is some infamous brand chineese name Eilondo
and on the camera all that is written is SUPER USB2.0 1.3 mega pixel

I bought exactly this camera because I was said by the shop reseller that the camera works without any driver installations on Windows XP and Windows Vista

On my Debian Squeeze GNU / Linux it was detected in dmesg without any troubles, here is how the camera got detected in my kernel log :

[25385.734932] usb 2-1: USB disconnect, address 4 [25388.905049] usb 2-1: new high speed USB device using ehci_hcd and address 5 [25389.050753] usb 2-1: New USB device found, idVendor=1e4e, idProduct=0102 [25389.050757] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [25389.050760] usb 2-1: Product: USB2.0 Camera [25389.050762] usb 2-1: Manufacturer: Etron Technology, Inc.

I was troubled by the message uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround. , and hence looked for an application to test if the camera can recored properly.

While checking in packages available in Software Center , I found a plenty of programs under the search keyword Camera
I however decided to test it using just one application Cheese - A tool to take pictures and videos from your webcam which I've seen to be quite popular among Liunx users.
Cheese is part of GNOME Desktop, so that was another reason I decided to give it a try. I was pleasently surprised about how good these tiny but functional proggie is.
Cheese has capabilities to take pictures, a consequential photos take up, as well as create Video movies.



The program has support to apply 12 Effects / (Masks) to add some fun to the pictures or video snapshots.



Probably the best thing about Cheese is its simplistic interface, which for me personally is a main criterion to evaluate a program quality ;).

Do you remember the old arcade spaceship shooter Xenon 2 Megablast? I do For all those who are too young to remember, here are two screenshots:





Even though Xenon 2 Megablast original can now be played using dosbox DOS emulator. Its interesting to mention I've found two Linux games that more or less can be qualitified to resemble Xenon 2.
The games are Native Free Software games and existing in package repositories of most Linux distributions and *BSD port trees.

Geki 2 and Geki 3 are of a less quality to Xenon but still, the game experience is nice and is among the Arcade shooter games to bring you fun in the boring days if you're on GNU / Linux or FreeBSD Free OS platforms.

Installing Geki2 and Geki3 on Debian and Ubuntu Linux is standard with apt:

debian:~# apt-get install geki2 geki3
...


On Debian GNU / Linux , after installed the games would not create GNOME Applications -> Games -> game startup shortcuts, however the game startups will get added in GNOME Applications Menu under:

Applications -> Debian -> Games -> Action -> Geki 2
and
Applications -> Debian -> Games -> Action -> Geki 3


The games can be launched also manually with commands:

geki2



or

geki3


Geki 2 is a way closer to Xenon 2 as it has similar look and feel and the same vertical direction the spaceship is navigated.
In Geki 3 still the shoot 'em' up spaceship like arcade is present, however instead of penguin you have to fly a flying penguin instead of spaceship and the move on direction is horizontal.
Both the games have the same sound and music effects. The game music and effects are not of top quality but are not bad as well and surely gives some of the arcade atmosphere.


Geki 2 Xenon 2 Megablast like on Debian Linux

In the tradition of the arcade games at the end of each level in both games you face the Level Boss Enemy, you should destroy.


As you can see in below's screenshot the overall graphics of GEKI 3 is poorer if compared to GEKI 2



still GEKI 2 gampley is fun and addictive and I would say not less enjoyable than GEKI 2.
At times I even think that Geki 3 is more fun because of the game's dynamics.

Maybe the reason, why I enjoyed more Geki 3 is also the fact that Geki 2 is a way harder. Dying only 3 times in the game you get GAME OVER and the next game you're started from the beginning of the same level you died in.



Something really annoying that affects both the games is there is no option to play them in Fullscreen mode.

Game controls for Geki2 and Geki3 are identical:

Up - Arrow up key
Down - Down arrow key
Right - Right arrow key
left - Left arrow key
Shoot - z or Space
Pause - s


Geki2 and Geki3 are fun and can kill some time, but definitely aren't that (professional) as other spaceship shoot'em'up arcades like Starfighter , Critical Mass or powermanga
, though that they're two worthy games to install and keep on your Free Software OS.

Do you remember that oldschool Arcade VolleyBall game which was so popular on 16 bit (8086 XT) computers.
I remember this game from the years I was 12 years old, back in the days where we the gamers distributed all the DOS games on 360 KB 5.25" diskettes

I was looking over the games available to install on my Debian GNU / Linux today just to be happily suprised to find GPL Arcade Volleyball an identical game remake of the old Arcade Volleyball 8086 classic freeware game.


I remember we spend many hours with friends playing on the old Manifactured in Bulgaria Pravetz 16! computers
During communism and post communism Pravetz was the only computer brand we could buy from the market, as there was limitations on the exported and imported tech equipment within the USSR union.
Pravetz computers are a literal remake of 16 bit IBM 8086 computers and the computer design and integrals was stolen from IBM 16 bit 8086 / 8088 PC architecture

Arcade Volleyball has set a mark on my generation and I believe many people will remember the times this game was a hit with a bit of Nostalgia ;)


Besides being an identical remake of PC Arcade Volleyball , GPL Arcade Volleyball is even expanded as it includes extra features which the original game lacked. Game includes:

• Network Volleyball client / server Game (up to 4 players)
• 6 Game Themes which completely change the game look & feel to be modernistic

Here are few GAV screenshots of the different existing game Themes:






Yisus GAV Theme gameplay screenshot




GAV - Unnamed Theme Gameplay


GAV - FaBeach Theme Gameplay

GAV supports both Window and fullscreen modes. To enable Fullscreen mode, while inside the game use:

Extra -> Fullscreen (Yes)


Saving preferences is also something which I if I recall correctly the original game lacked. This is done by navigating to:

Extra -> Save Preferences


GAV is said to support Joystick in resemblance to the original DOS game, though I've never tested it with a joy.

One of the greatest GAV game (hacks) is the Inverted Theme. Selecting it inverts the order in the game, where the game player becomes the volleyball ball and the ball becomes the player ;)


GAV does not yet not have a Free / Open / Net BSD port as far as I currently see, anyways since the game is Free Software probably soon a port will be available for BSDs as well.
The default GAV game controls are a bit untraditional. By default the one player game starts you play Volleyball game player positioned on the left.

For left player the default control keys are:

• z - move player left
• c - move player right
• left shift - jump

Right player controls are:

• Left - left (arrow key)
• right - right (arrow key)
• jump - up cursor key

GAV supports also a shortcut key for switching between windowed and full screen game mode by pressing F10
Installing the game on Debian and Ubuntu Linuces is done with:

linux:~# apt-get --yes install gav


Unfortunately gav does not have a definition to be added to GNOME or KDE Applications menus, thus to start the game after installed one has to do it manually by typing either in gnome RUN (Alt+F2) or on command line:

linux:~$ gav


Happy playing ;)

As a Child I've been baptized in the Orthodox Church and since then I've been a complete atheist until the age of 21.
What is the reason to get my faith in God in 21? This is a short post to shed some light on the great efforts of communism to erradicate faith in God in Communistic countries and change faith in God with faith in man and how this kind of approach devastates societies.
During the communism it's a well known fact that communists, all the members in the Bulgarian Communist's Party (BCP), has led an anti Bulgarian Orthodox Church government politics. The fact that Communistic Governments are fighting Churches and faith in God is less known among youngesters and hardly known by people part of western democratic societies.

I did not lived this time myself, but I heard many stories about the stupidities of communism.
Many older people say, when communism came to rule the Communist Government did immediately destroy some Orthodox Christian temples, some priests were convinced in crimes they were not responsible for etc...
Other priests were send in the Concentration camps and many of them never returned in the society.
"Access" to the Churches was limited and sometimes prohibited to the orthodox layman and often to clergy.
During these terrible communism era, it was prohibited to everybody who is a member of BPC to attend Orthodox Church services or identify himself as christian in public.
I've heard from my grandma an interesting story she witnessed, while she was working as a cleaner in the militia (police).
Here is the story:
One day my grandma wanted to go to the Church St. George located on the city centre of Dobrich city Bulgaria.
A policeman stopped her when she was entering the temple and since he knew her as an employee in the police called her by name and told her that she is not allowed to enter the church building, because she is working in the police.
My grandma asked the militiaman to let her enter the temple to pray for just few minutes and light up a candle (just for this time) without reporting for that in the police.
The policeman agreed to let us in and keep silent that she entered the Church this time,but warned her that if he sees her another time entering the church he is going to report to the respective authorities.
Another part of the Government active politics against the Bulgarian Orthodox Church was by placing an ex-criminals who were sentenced for thefts, rapings, agression or other crimes as a priests in the Church.
By this move the supreme counsel of the bulgarian communist party wanted to break the people confidence in the Church as the true holy apostolic Church. The most fierce communists during these days did their best to present the church of God as a corrupted and void institution who only steals from people and exists only to deceive society.
Yet many years after the fall of communism this people distrust in the church that communists sow through the years.

What is pity is even after the communism is gone for a long, time the churches are only full on biggest feasts and no more than 5% of the citizens are regularly going for Church service or have even the basic knowledge on the Church truths and mysteries.
Following the fall of communism the democratic governments who come to power, elected in a citizen democratic elections did not do much to help the church either, some of them does lead politics openly hostile to our Bulgarian Church.
The last government selected, seems to be less hostile to our Church, but people have once been cut away from the Church and now its really hard for our nation to get back to faith.
The severe crisis (a word that means judgement in greek) and the hardships many people experience started to make some people rethink about what is the meaning of life and made them occasionally go back to faith of our fathers orthodoxy.
What will happen further nobody knows, we need to pray and hope God will have mercy and people will repent for their sins and come back to faith again.

Alex the Alligator is a Free Software (Open Sourced) arcade game licensed under the General Public License (GPL)
The game is quite of fun and especially the music totally kicks ass! ;)

The game plot is simple but fun in the good Spirit of oldschool Super Mario like arcade games.


In the game you are a little cute crocodile whose (crocodile) girlfriend is kidnapped with a helicopter by the evil human poachers.
As you love her too much and you're determined to grow a crocodile family with this croco-girl you start a long quest to save her from possible zoo slavery or killing for a crocodile skin boots.


The quest for kidnapped girlfriend (LOLA) liberation wents through the harsh jungles.




Alex The Alligator has a version for both Windows and Linux ports. The Linux port is available for most major distributions including Debian, Ubuntu, Fedora etc.

To install the game on Debian and Ubuntu with apt-get issue:

debian:~# apt-get --yes install alex4
...


After installing the game can be run from command line using cmd:

alex4


The game controls are as follows;

• Arrow Keys - Movement
• Alt - Jump
• Ctrl - Fire (if you have previously collected Eggs

Alex the Alligator is also equipped with a MAP editor, so if you really want to contribute the game development, take some time create some maps and submit to game's official website http://allegator.sourceforge.net/ . On the game website there are few other variations of the Alex the Alligator as well as extra game maps.
Explanation on which keys can be used to create maps is found in the game manual, e.g.:

debian:~$ man alex4


If you have downloaded some extra game maps from the game sourceforge website, to load them you can use:

Shift+L

Will Alex succeed in saving his girlfriend ? It's up to you ;)

Nikwi Deluxe is another good quality jump and run game for Linux

The main actor you play with is a (Dexter like) looking kid who has to collect all candy items on the level screen. The game graphics are quite a good level if compared to the most Linux jump and run games.

Your game hero is not equipped with any weapon or (jump over the enemies like in Maries) and you not haven't got any mean to kill enemies, but you have to always avoid them. There are some funny looking crawl (birds) shitting from the above every now and then, if you're hit by a the bird's droplet you die. The game has 30 levels and after each level succesful completion you're provided with a password that can be used as a "Save Game" like if you quit from game and on next game run you would like to start directly from the last game level you reachedNikwi Deluxe is another good quality jump and run game for Linux




The only game downfall is the missing music as well as the not too brilliant sound. To boost my game experience, however put some background music and give the game a try ;)

Have you ever wondered, if there is a free (open source) software that could fix Windows XP registry irregularities e.g. (obsolete or unwanted items that build up in the registry over time.)?

I did not either until now, however when I had to fix, few Windows XP computers which was not maintained for a long time fixing the Windows registry was necessery to make the sluggerish computers improve their overall stability and performance.

The reasons of the slowness in computers who run for a long time by users who does not have a "computer culture" are obvious.
Windows programs which has incorrectly placed registry records withint the Windows registry database, Programs which on Uninstall / Removal left behind a lot of registry records just to hang around because of impotent (coders), or records created on purpose on program uninstall to intentionally further track the user behavior etc.
Other reasons why Windows registry gots bloated with time, are due to Malware or polymorphic Viruses which load them selves everytime on Windows load using some obscure registry records.

Though I'm not a big proprietary software lover still my job as a system administrator , enforces me to fix some broken Windowses.
I haven't fixed Windows machines for a long time, so my memories on programs that clean up registry are from my young years.

The software, I've used before to fix Windows 2000 / XP Registry was:

1. Registry Booster

From my current perspective of a free software hobbyist / evangelist it was important for me to clean up the Windows PCs with a program that is Free or Open Source Software.
When I'm asked to fix some Windows computer I always do my best to make most of the programs that roll on the PC to be FOSS.

Using FOSS instead of downloading from torrents, some cracked software has multiple benefits.

1. Usually Free Software is more stable and more robust 2. FOSS software for Windows usually does not come with Malware / Spyware as many of the cracked proprietary software

3. Free and Open Source Programs are simplistic in interface and way of use

A bit of research if there is a Free (Open Source) Software immediately lead me to a program called Little Registry Cleaner
You can see a screenshot of the program in the beginning of the article, the program is very easy to install and use and uses some .NET framework classes so right before installing it installs .NET library (code).

The use results of Little Registry Cleaner were amazing. Even though it is a free software the program found and fixed more registry problems than its competitor Windows Registry Booster! ;)

1. Frogatto & Friends - Is an Indian Free Software (Open Source) game in the spirit of old-school jump'en runs like Commander Keen, Prehistoric, Jazz Jack Rabbit

The game is really entertaining, the graphics looks approximately nice, the music is awesome, the gamelplay is good even though after some point in the game the moment with "where should I go now, I can't find exit" comes through and it gets boring.

Generally if you compare with all the existing jump and run arcade games free software games available for Linux and FreeBSD the game will definetely arrange itself in the list of TOP 10 free software Arcade Games
and therefore its my own believe that Frogatto is a game that every GNU / Linux and FreeBSD desktop should have in Application -> Games GNOME menu.

Frogatto is rich of levels, enemies obstacles objects, places to visit (which puts it ahead of many of the linux arcade games which often miss enough game levels, has a too short game plots, or simply miss overall game diversity).



The game's general look & feel is like a professional game and not just some tiny free software arcade, made by its authors for the sake to learn some programming, graphics or music creation.




Besides that Frogatto & Friends is multi-platform supporting all the major operating systems.
Game supports:

• Windows
• Mac
• iPhone
• Debian GNU / Linux
• FreeBSD

The game source code is also available on Frogatto.com - The Game's Official website

The game is available as a deb package in Debian and Ubuntu GNU / Linuxes so to install on those deb based distributions, simply use apt:

debian:~# apt-get install frogatto
...


The above command will install two packages frogatto (containing the game's main executable binary) and frogatto-data containinng all the game textures, levels, graphics, music etc.

BTW the package saparation on a gamename and gamename-data in Debian (for all those who have not still noticed), can be seen on most of the games with a game data that takes more disk space.

After the game is installed the only way to start the game is to run it manually through pressing ALT+F2 in GNOME or running the progrtam through gnome-terminal with cmd:

debian:~$ frogatto


Here are few more Frogatto gameplay screenshots:






I've noticed Frogatto is also available as an RPM package for Fedora Linux, as well as has a FreeBSD port in the /usr/ports/games/frogatto and this makes it easy to install on most free software OSes in the wild.

While checking frogatto.com , I found an interesting link to a website offering free graphics (pictures), textures and sounds for free and open source games for all those who hold interest into the development of Free Software & Open Source Games make sure you check OpenGameArt.org

OpenGameArt.org looks like a great initiative and will definitely be highly beneficial to the development of more and better FSOS Games so I wish them God speed with this noble initiative.

Frogatto is very suitable for growing kids since it doesn't contain no violence and every now and then the main game actor the Frogatto Frog leads few lines English dialogues with some of the characters found in the quest.
For none speaking English countries, the game can help the kids to learn some basic english words and thus can help develop kids intellect and knowledge
And oh yeah one more criticism towards the game is the Enlish structure, it seems people who wrote the plot can work this out in the time to come. Many of the English sentences during dialogues the frog leads with the cranks he met does not sound like a common and sometimes even correct english / phrases.

Besides those little game "defect", the game is pretty awesome and worthy to kill some time and relax from a long stressy day.

I'm writting some game reviews and movie reviews, every now and then and therefore being able to capture a fullscreen running program like let's say mplayer or vlc or some full screen running game is something I really need.

The usual PrtScr button which normally works to prepare screenshots in GNOME or KDE, however is not working if the root window handler is being passed to a different program than the Window Manager and pressing it while inside of many older programs or applicationsdoes not produce a print screen of the current screen.

Anyways I found a hack to this using the good old ImageMagick - import command line screenshotting program.

To take a screenshot of a certain program run from gnome-terminal or konsole using import cmd its possible to use a quick one liner which will take a snapshot of the root Window the started program will use.

Let's say you want to make a screenshot of the entry screen of the FreeDOOM (DooM 3d shooter classical game arcade free Software Alternative).

Launch gnome-terminal or konsole , xterm , depending on the GUI environment you use and issue the commands:

debian:~$ ( sleep 15; import -window root my_desired_screenshot_name.png ) &
debian:~$ freedoom


The first command will launch import after a sleep of 15 secs and therefore will screenshot the active window which will be at focus after 15 seconds, where the & sign will background it and the second one will launch FreeDooM . You will have to wait for a certain secs and switch to the exact screen you will want to screenshot.
If you want to screenshot some game scene that will appear in 20 minutes change above sleep 15 cmd to be to something like sleep 180
That method can be used for screenshotting any other program running on fullscreen, the method is a bit inflexible as you will have to adjust a timing but it works fine ;)

While looking over the installable packages in System -> Administration -> Software Center on my my Debian powered notebook, I've accidently rolled over a game called Abe's Amazing Adventure , as a big oldschool arcade game fan, I've immediately clicked on Install being impatient to see the overall game atmosphere and gameplay as well as storyline.

Abe's Amazing Adventure is available under the debian package name abe and can be installed by issuing:

debian:~# apt-get install abe
I was pleasently surprised to find out the gameplay and the overall game feels like the golden classical arcade game Dangerous Dave

For youngsters who never played the amazing absolute killing arcade ! as well as for people who feel nostalgic about Dangerous Dave 2 here is a nice gameplay screenshot:



Here is also a screenshot of Abe's Amazing Adventure gameplay:



You can see the great resemblense between the two games even by the screenshot; In both games you have to collect keys to open doors and diamonds which gives you points. Of course there are some differences as you can see Abe's Amazing Adventure 's graphics has some additional items like Baloons with which your main character can fly over distances (for a limited time). There is also more diversity in the enemy types you face on the road to unlock the different doors. The game has also a red stars which while taken saves the game so if you quit the game on next game load up starting the game automatically starts you from the last save point.



The ( 6 ) baloons seen in the screenshot on the left upper corner can be used occasionally to fly some distance by pressing Enter .
There are health recovery kits one can take to recover, some health damaged by hitting obstacles on the way.
The game story is short but entertaining, just like the general game feel:


The game music is relaxing and more or less in the spirit of arcade games, the keyboard interactivety is pretty good as well. One thing I see can be improved to make the game better are the graphics, they're a bit childish and too cubical, where sometimes some more general characters and obstacles animation will give the game a better look. Anyways for the year 2003 and for a free software arcade the game is not bad. For children and growing kids the game is just perfect, even for big kids like me its good to spend an hour of jump and run fun ;)

UNetbootin is a nice easy to use Free Software Universal mutli OS program that makes creation of Bootable USB Stick Linux, FreeBSD, NetBSD and other free operating systems a piece of cake

UNetbootin support the three major operating system architectures Windows, Mac OS X and GNU / Linux .
In Debian and Ubuntu based distributions Unetbootin is available as a deb binary package:

debian:~$ dpkg -l |grep -i 'usb' |grep -i 'install'
ii unetbootin 471-2
installer of Linux/BSD distributions to a partition or USB drive


To install it with apt:

debian:~# apt-get install unetbootin
...


debian:~# unetbootin


Alternatively for all those who prefer to run it via the GNOME Application menu follow to the menu path:

Applications -> System Tools -> Unetbootin


If the program is launched with non privileged account (like via GNOME Application menu), in order to to properly tamper with any connected USB Flash drive you will be asked about the super user password.

The shipped uniboot version in current Debian stable version Squeeze is 471-2 is a bit outdated. For everyone eager to use the latest version which as of time of writting is 565 check out UnetBootin's Official Homepage on SourceForge

Installing the distributed binary of unetbootin downloadable from its website is a trivial one. Simply download the file from the Download (for Linux) link and run the binary unetbootin-linux-565:

debian:~$ ./unetbootin-linux-565


There is one annoying thing about the latest downloadable (static compiled) unetbootin version, it was built to run using KDE's QT library and therefore the interface that poped up while trying it was KDE like, pitily did not take advantage of my native GNOME GTK2 library :

Though this little note, unetbootin developers has done a truly great job! I tried unetbootin and was more than pleasently surprised that it prepares bootable USB sticks with only 4 mouse clicks!!! ;)
The program worked out of the box without any external or additional hacks like many of the programs I daily use it just worked ;)

UNetbootin has a thoroughful list of Free Software operating system distributions in the distributions list. Many of the offered Open Source & Free Software distributions has even possibility of installing a multiple versions of the respective distro.

Here is a complete list of all the Free & Open Source Operating Systems, unetbootin program can burn and make bootable on USB stick.

• 1. Ubuntu

To burn and make bootable on the USB flash drive any of the listed distributions, choose the distribution name and version number as well as the Drive: (which usually will be selected by default to the first sticked USB drive let's say /dev/sdb1).
Afterwards press on the OK button and that's it, lay down your back and wait until the distribution is downloaded from the Internet, burned into the USB pendrive and made bootable.
I've tested Unetbootin with two distributions;
1. Xubuntu 10_04_live and;
2. Fedora 13

Both of the distributions got burned properly to the CD drive and booted fine on a Packard Bell notebook on which I booted them from the USB.
Having an USB drive with LiveCD GNU / Linux or BSD everywhere with you is handy. Now I can move to any PC installed with Windows and use my preferred Free Software OS.
Besides that, there are laptops whose CD-ROM / DVD-ROM drive is broken and therefore if one wants to re-install an improperly working Windows XP / Vista / 7 and substitute with Free operating system this task is only possible using USB Flash Disk or NetBoot Install.
Installing using USB has its advantageous as you don't depend on the network as well as the installation from USB is in most of the cases few times faster.
There are plenty of other USB Linux installer programs, most of them however are only available with a Windows version.
Here are few prgrams which can be used to burn a number of Linux and *BSD installations using Microsoft Windows to create Linux / BSD liveUSB:

• Universal USB Installer - http://live.learnfree.eu/download
• 
  
• YUMI - Your Universal Multiboot Installer - http://www.pendrivelinux.com/yumi-multiboot-usb-creator/
• xBOOT - http://sites.google.com/site/shamurxboot/
• 
  I was happy to find outUniversal USB Installer (a proggie written in Python) is made by a Bulgarian mate! Proud to be Bulgarian ;)
  Universal USB Installer is actually multiplatform since written in Python and in this number can be used to burn a LiveUSB on GNU / Linux and (possibly on FreeBSD?)
  
  I would be glad to get feedback from other people who had experience with programs to prepare LiveUSB bootable sticks on Free Software OSes. Does anybody tried that on who *BSDs? Cheers ;)
  

Facebook and Youtube has become for just a few years a defacto standard service for 80% of computer users in our age.
This is true and it seems there is growing tendency for people to adopt new easy to use services and a boom in the social networks.
We've seen that with the fast adoption of the anti-human freedom program Skype , the own privacy breaching FaceBook as well as the people interests tracking service YouTube.

We've seen similar high adoption rates in earlier times as well with the already dying (if not dead MySpace), with the early yahoo mail boom etc and in even earlier times with the AltaVista search engine use.
However this time it appears Youtube and FaceBook are here to stay with us and become standard online services for longer times ...
Many people who work in office all day staring in a computer screen as well as growing teenagers and practically anyone in the developed and the development world is using those services heavily for (in between 5 to 10 hours a day or more). The Software as a Service users spends approximately half of their time spend on the internet in Youtube or and Facebook.

Its true Youtube can be massively educative with this global database of videos on all kind of topics and in some cases facebook can be considered helpful in keeping in touch people or keeping a catalog of pictures easily accessible from everywhere, however when few services becomes more used and influential than other provided services on the internet this makes these services harmful to the communities and destroyes cultures. The concentration of most of the human popuplation who uses high technologies around few online services creates a big electronic monopoly. In other words the tendency, we see of amalgamation of businesses in real world (building of big malls and destroyment of small and middle sized shops is being observed in the Internet space.

Besides that Facebook and Youtube and Twitter are highly contrary to the true hacker spirit and creates a big harm for intellectuals and other kind of tight and technical community culture by creating one imaginative casual disco culture without any deepness of thought or spirit.

Its observable that most of the people that are heavily using those services are turning into (if not exaggerate) a brainless consumer zombies, a crowd of pathless people who watch videos and pictures and write meaningless commentaries all day long.

You have as a result a "unified dumbness" (dumbness which unifies people).

Even if we can accept the grown and fully formed character people are aware of the threats of using Youtube or Facebook, this is definitely not the case with the growing people which are still in a process of building personality and personal likings.
The harmful resuls that the so called Social networks create can be seen almost everywhere, most of the cafeterias I visit the bar tender uses facebook or youtube all da long, most of random people I see outside in a coffee or university or any public institution where internet access is available they are again in Youtube and Facebook. The result is people almost did not use the Net but just hang around in those few services wasting network bandwidth and loading networks and computer equipment and spending energy for nothing. The wasteful computer and Internet deepens the ecologic problems as energy is spend on nonsense and not goal oriented tasks but on "empty" false entertainment.
Hence the whole original idea of internet for many is changed and comes to few words ( Skype, Youtube, Facebook etc.

Besides that youngsters instead of reading some classical valuable books, are staring in the computer screen most of their cognitive time at only this few "services" and are learned to become more a consumers than self opinion thinkers and inventors.
I have not lately met any growing real thinking man. I've seen already by own experience the IQ level of younger generations than mine (I'm 28) is getting downer and downer. Where I see as a main cause the constant interaction with technology built in a way to restrict, a consumers technology so to say.
Facebook and Youtube puts in young and growing man's mind, the wrong idea that they should be limited choice people always praising what is newest and brightest (without taking in consideration any sight effects). These services lead people to the idea that one should always be with the crowds and never have a solid own opinion or solid state on lifely matters. As said own opionion is highly mitigated especially in facebook where all young people try to look not what they really are but copy / paste some trendy buzz words, modern style or just copying the today's hearoes of the day. This as one can imagine prevents a person of getting a strong unique self identity and preference on things.

Many of the older people or computer illiterates can hardly recognize the severe problems, as they're not aware on the technical side of things and does not realize how much security compromising as well as binding the constant exposure to those online hives are.
The purpose of this small post is hence just a small attempt to try to raise up some awareness of the potential problems, we as society might face very soon if we continue to follow the latest buzz trends instead of stop for a moment have a profound think on what is the moral consequences of giving so much power on Internet medias like Facebook and Youtube? ...

Yesterday, one (girl)friend of mine brought me one Packard Bell notebook, which had a 2 years old Windows installed on it.
As one can imagine Windows XP on it is full of Spyware and Viruses. Besides the software problems the notebook had some hardware problems with the CD / DVD which is not reading CD / DVDs at all.

Initially I thought, the CD unable to read problems are caused by the infected Windows, however even restarting the PC with a bootable Hirens BootCD and a Whoppix liveCD and trying to boot from it failed this convinced me its a CD / DVD combo drive hardware failure.

By the way, I've just recently found out about Nixory - Is a nice Free Software Open Source AntiSpyware tool for Firefox, IE and Chrome.



I hope it will get a sharp development and soon, when some friend asks me to fix his stupid non free-Windows PC, I would not have to use a trial version of Malware Bytes but directly use only Nixory

Anyways after using Nixory, MalwareBytes and Avira and thoroughfully scanned the system in Safe Mode and found and deleted some 15 Spyware / Viruses and tampered a bit with the Wireless Driver settings all the notebook devices started working fine again.

The wireless had also one really odd problem on this Packard Bell - Hera GL, even though the notebook wireless antenna was capable of detecting all the wireless networks it couldn't properly connect to any of it but failed to get proper IP addresses.
Partially the unable to grab an IP via wireless router dhcp server got fixed by using the Wireless restart Button (located on the Notebook corpus).
However even after cleaning up the Virus and Spyware the Wireless Networks connectivity problems on this Packard Bell continued, until I changed also few settings in the Control Panel I never thought Viruses / Spyware infected can have some bad impact on Wireless Card and CD drive make them unsusable though they showed like working correctly in Windows Control Panel -> System ??

In the meantime I reinstalled the Wireless Driver for the notebook, the Wireless card on the notebook was showing up itself under the name of Ralink 802.11n Wireless Lan Card in Windows Device Manager

After re-installing the wireless driver I had to also change few settings for the Wireless Network Connection using the menus Properties -> Configure -> Extended; therein everywhere for each Value I make it be Enable and for Power Saving Mode , I've choose the Value option of CAM

After a system reboot, everything started working finally fine. One last thing to add is that before I fixed the Ralink wireless to work under Windows, I tried to use a Bootable Linux LiveCD but even there the wireless was failing to connect to the wireless networks (maybe this shit wireless device has some issues with its Linux drivers).

One of the Debian servers's SSH daemon suddenly become inaccessible today. While trying to ssh I experienced the following error:

$ ssh root@my-server.net -v
OpenSSH_5.8p1 Debian-2, OpenSSL 0.9.8o 01 Jun 2010
debug1: Reading configuration data /etc/ssh/ssh_config

...
Connection closed by remote host


Interestingly only the SSH server and sometimes the mail server was failing to respond and therefore any mean to access the server was lost. Anyways some of the services on the server for example Nginx continued working just fine.
Some time ago while still working for design.bg - web development company, I've experienced some similar errors with SSH servers, so I already had a clue, on a way to work around the issue and to secure myself against the situation to loose access to remote server because the secure shell daemon has broken up.

My work around is actually very simple, I run a secondary sshd (different sshd instance) listening on a different port number.

To do so I invoke the sshd daemon on port 2207 like so:

debian:~# /usr/sbin/sshd -p 2207
debian:~#


Besides that to ensure my sshd -p 2207 will be running on next boot I add:

/usr/sbin/sshd -p 2207


to /etc/rc.local (before the script end line exit 0 ). I do set the sshd -p 2207 to run via /etc/rc.local on purpose instead of directly adding a Port 2207 line in /etc/ssh/sshd_config. The reason, why I'm not using /etc/ssh/sshd_config is that I'm not sure if using the sshd config to set a secondary port does run the port under a different sshd parent. If using the config doesn't run the separate ssh port under a different server parent this will mean that once the main parent hangs, the secondary port will become inaccessible as well.

Yesteday with Baky (my dear Orthodox Coptic Christian friend) and Kliment (a good friend from the old rock'n'roll years), we went to the Dobrich Cinema (sadly just one cinema for the city is available). The cinema in Dobrich is called Cinema Club Icarus (Ikar). For all foreigners who wants to enjoy some movie, the Dobrich Cinema does offer a plenty of English speaking movies (with Bulgarian subtitles).

Pitily the Dobrich Cinema website http://www.kinoikar.com/bg/info/2 is not existing in English, though anyone wanting to check the current projected movies in the cinema can use the movie trailers and the movie pictures to get the necessery info.

Anyways I haven't been to a cinema for some almost two months, so going for a movie was really relaxing enjoyable experience. Besides that, we were lucky to see a movie which fitted quite well to my movie genre preferences -

Midnight in Paris . Midnight in Paris is a Romantic Comedy for intellectuals and people who have a glipmse on art. Its a Bohemian movie so to say and I believe it wouldn't hold a big interest for the avarage man who doesn't keep interest in Arts, History or Philosophy.

The movie plot revives around a young engaged American couple who went to Paris for a business trip, just to find out there whole life is gonna be changed by this.
The main actor Gil a just grown man is writting a Novel book, trying to make a shift of his profession from being a movie directory to a novel publicist. Gil (Owen Wilson) is an odd Bohemian kind of man, who quickly fells in love with Paris rich culture architecture and old fame.
Next to that Gil is a dreamer who (just like me dreams about the old glorious times), when people were more respectable better moral and more idealistic than in the current age. After one night of heavy wine drinking, Gil's fiancee wents for some dancing and leaves him on his own. Gil makes a round in Paris and losts himself and decides to stay for a while in front of sold old Roman Catholic Cathedral, a mysterious very old car crosses by the street and suddenly some "party" gang asks Gil to join. He has no idea where he is going and suddeny finds himself in the epoch of the world famous 1920 of great book publicists like the Fidgeralds family.
Night by night Gil is being transferred to a different epoch back in time to meet a world famous artists and authors, people like Ernest Hemingway, Picaso, Salvador Dali etc. etc. ;)

The movie shows many personages of odd world famous people with some of their strangeties known by the current age. It appears all of them are dreaming for all and the same thing, to live in a earlier age to live in the Golden Age of Arts and Poetry ;)

The movie is real fun in Gil's personage I've seen a lot of "me", also I've seen a lot of me in many of the other famous people as of course presented in the movie. I hardly recommend this movie to anyone who wants to take a break, have a good mindful laugh time.
Here is Midnight in Paris movie trailer as well to get an idea what to expect:
