Meaningless_life-picture

Seems, My life is going nowhere. Today I drinked half of a bottle of Wine and 1 beer. I was out with Alex. We drinked in the city park. Through the day I started my first bsd jail using a tutorial online. I smoked a lot of cigarettes and I want to stop them again. Most of the people I met are not a good company for me that's what I'm thinking more and more. Also I'm thinking more and more I have to change my living place. If only I could find the love of my life … We moved bookshelf and stuff from our room ( My mother again has decided to make repairs in our room. ). I'm asking myself why shall I live a meaningless life. At least my interest into computers and computing started to appear again (this is cool). My faith is really going away since I pray and pray for something .. and I don't receive it ( Or at least I don't see it). I'm tired of waiting. I need to have this physical healing to continue my normal life. I'm not proud of me I was a little aggressive when we was in the Mino's coffee before an hour or so … Now I intend to watch another episode of stargate SG1. And to go to the DreamLand. If only I could live into a Dreamland all the time. I'm starting to realize I should change the music I listen, I should change a lot of my behaviours If I want to have a new and happy life. Autumn is a beautiful Season 🙂 The autumn rain shall come and restore us :)END—–

Downloading your favourity flash video from Youtube with a simple command (youtube-dl)

Watching videos in youtube today and already for about 2 years is the de-facto hype.
There is almost none a day passed without almost each one of us has watched a dozen videos in Youtube.

Watching videos in youtube has become even more addictive for many than the early days of Internet Relay Chats (IRC)

As youtube is very accessible for people and it’s a comparativily easy way people share more and more with the day.
There is no question that the business idea of youtube is great and youtube generates millions of dollars for Google day by day, however I have a serious objection here! All is good the only pitfall is that you don’t own the youtube videos you watch!

Youtube’s story is not that different from the story of the cloud computing threat to internet users Freedom

The good thing here is that we’re not still completely dependant on youtube and there is still way to retrieve your favourite youtube video and store it for later watching or distribution.

Probably the most famous browser plugin that allows files retrieval from youtube, as most people know is DownloadHelper .

However using download helper is browser dependant, you need to use the browser to save the plugin and I don’t find it to be the best way to download a youtube video.

Since the old days I have started using Linux, I’ve been quite addicted to as many things on my linux as possible from the command line (terminal / console)(CLI) .

In that manner of thoughts it was a real delight for me to find out that a group of free software developer guys has come up with a command line tool that allows downloads of youtube videos straight from terminal, the great software is called youtube-dl and at the moment of this post writting it’s to be found on the URL address:

http://rg3.github.com/youtube-dl/

Youtube-dl is written in python so, it requires the Python interpreter, version 2.5 in order to properly run on Unix, Mac OS X or even on Windows!

The fact that it’s written in python has made the little shiny tool quite a multi-platform one.
To start using immediately the tool on a Debian or Ubuntu Linux you will have to install python (even though in most cases you must have it already installed):

1. To make sure you have python interpreter installed issue the cmd:

debian:~# apt-get install python
Building dependency tree
Reading state information... Done
python is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

As you can see from above apt-get’s output I do have it installed so nothing gets installed.

2. As a next step I used links to download the youtube-dl python script, like so:

debian:~# links https://github.com/rg3/youtube-dl/raw/2011.03.29/youtube-dl >> youtube-dl
Use the links interface to save youtube-dl and use gzip to ungzip it
debian:~# gzip -d youtube-dl.gz
debian:~# chmod +x youtube-dl

Now to make it system wide accessible I have copied the youtube-dl to /usr/local/bin , whether I selected /usr/local/bin as a location as this location is predetermined to contain mostly files which does not belong to a regular deb package.

3. Move youtube-dl to /usr/local/bin

debian:~# mv youtube-dl /usr/local/bin

4. Test the newly installed youtube-dl command line youtube retrieval tool:

debian:~# ./youtube-dl https://www.youtube.com/watch?v=g7tvI6JCXD0
[youtube] Setting language
[youtube] g7tvI6JCXD0: Downloading video webpage
[youtube] g7tvI6JCXD0: Downloading video info webpage
[youtube] g7tvI6JCXD0: Extracting video information
[download] Destination: g7tvI6JCXD0.flv
[download] 53.3% of 22.62M at 33.23k/s ETA 05:25
[download] 100.0% of 22.62M at 31.91k/s ETA 00:00 [u

As you might have noticed from the above youtube-dl command output the newly retrieved youtube file will be saved under a name g7tvI6JCXD0.flv

The line I passed to youtube-dl is directly taken from my browser and pasted to console, the file downloading from youtube took me about 10 minutes but this is mostly because of some kind of youtube server speed restrictions …

In general at least I have this video for later, watching, so after a while I can watch it once again without loosing a lot of time trying to remember what was the video headline name

5. To use youtube-dl in a bit advanced way you can for instance invoke the command with options like:

debian:~# ./youtube-dl -l -w -c https://www.youtube.com/watch?v=g7tvI6JCXD0
[youtube] Setting language
[youtube] g7tvI6JCXD0: Downloading video webpage
[youtube] g7tvI6JCXD0: Downloading video info webpage
[youtube] g7tvI6JCXD0: Extracting video information
[download] Destination: BSD is Dying, Jason Dixon, NYCBSDCon 2007-g7tvI6JCXD0.flv
[download] 4.4% of 22.62M at 1.43M/s ETA 00:15

As you can see now youtube-dl was even able to detect the downloaded video file name and store it on the computer with a correct name 😉

I would recommend you also to check out the youtube-dl help page, to do use command: youtube-dl –help
 

Kill everything that Moves (KETM) an arcade spaceship Tyrian GNU / Linux game

Saturday, January 7th, 2012

Reading Time: 3minutes

I always love so much to go back to the times, when games were games and people had still valued words like moral and respect.
In that great days of old school computing, we used to play the awesome old schools Tyrian and the Nintendo 1941 game (hopefully some still remember).

KETM Tyrian like Old School 2d Spaceship shooter awesome

For all who don't Tyrian is one of the best Spaceship Arcades of all times!, and especially for DOS operating system the best I've personally seen.

Recently I was checking the arcade games available for install on my Debian GNU / Linux and happily come across a game called KETM.

KETM acronym stands for the memorizable KILL EVERYTHING THAT MOVES and is free software distributed game under GPL.
The original creation idea was probably to resemble the so famous in the '90s spaceshooter games.

KETM is pretty addictive just like tyrian and has santimental meaning for me since it brings me memories for my arcade gaming years 😉

The game is easy to play and has a feeling of "diversity" especially in type of weapons your ship can obtain and use against enemies.

The powerups you get is quite plenty compared to the enemy ship types you should destroy 😉 In overall the game is quite easy to play, this however is also a good thing, as you can play more smoothly without dying every few secs like it is in so many arcade games…

The game has only 4 game levels and on each level end there is a big spaceship "the boss" which is the last in line to destroy in the tradition of the 2d arcade games.

KETM Tyrian like Linux Debian arcade game

Kill Everything That Moves is available for Debian and Ubuntu as a deb installable with apt. To install the game on Debian and Ubuntu

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

ketm's official latest available source and binary of time of writting this article is at version 0.6 and as far as I checked it unfortunately seems like the game development is stucked and the code seems a unmaintained.
I'm sure ketm has a lot of potential en hope somebody will adopt the code and will push further its development.
The game runs by default in the annoying windowed mode, I don't like this so I always run it fullscreen:

Kill Everything that Moves Tyrian like arcade game for Debian Ubuntu Linux

debian:~# ketm -f

KETM also reminds a bit on GEKI 2 / 3, which I have previously blogged about but I found KETM to be more enjoyable than gekis.
I've seen KETM has RPM ports as well so installing the game on fedora will be probably as easy as downloading the respective RPMs fulfilling the RPM package requirements and installing with rpm -i. I would be glad to hear from people who had succesfully run the game on Fedora and other RPM based Linux distributions?

The only thing that prevents the game to feel a bit more awesome (in my view) is the missing sound & music … Even though in the game settings inside the main menu there is an option for Sound On / Off the game runs by default without any sound or music (at least on my Debian).
I hope you will have some fun with KETM just I like I did! 😉
Also if you haven't played Tyrian yet, then I strongly advice you download Tyrian from here and try it out with dosbox (a dos gnu linux / bsd game emulator)

Absolute Game Classics Tyrian native game play with dosbox Linux screenshot

Interesting fact to mention here,  while looking for the native tyrian game info , I found tyrian has an open source version under development called OpenTyrian . I'll check the game and write on it when I have time.

Triumph of the Nerds – A documentary about the rise of Personal Computers

Saturday, October 8th, 2011

Reading Time: 3minutes

Triumph of the Nerds movie cover

Triumph of the Nerds is 3 parts documentary movie on how the Personal Computer was developed. The movie features interviews with Steve Jobs, Bill Gates, Steve Ballmer, Allan Paul and many other IT veterans who played key roles for the development of the Personal Computer ,

The movie is an interesting watching for people interested into Information Technology and gives some minor insights on the starred interviewed people and their life philosophy. It was interesting times back then and it seems many of the guys who could participate in the PCs were very lucky, where others who made key developments which are de-facto standards today went into history without much being remembered.

Now the trends which these man set in world’s development is not nice. Even though PC brough a lot of fun in our every lives it suddenly started taking over our privacy and made the humanity divided.
The movie is a story of a man motivated by greed arrogancy and exploitation. Even though the movie has historical value it doesn’t even mention about Free Software Richard Stallman and the free software movement.

The movie talks about the development of CP/M the predecessor of Quick and Dirty DOS (QDOS), MS-DOS Windows 1,2,3, Windows 95 etc.

It also tries to picture the events around the raise and fall of IBM and OS/2.

The most notable parts for me in the movie are the showing off of some old computer hardware and Mainframe servers as well as the quick explanation on how Mainframes irons predecessed the PC. Another interesting moment in the movie is displaying Steve Jobs demonstrating the Xerox’s Alto graphical interface. Talking about Jobs it was quite shocking for the world his sudden death just 3 days ago so (R.I.P).

The movie author Robert X. Cringery stress out in the movie the great struggle between the so called “the blue Elephant” IBM and the just emerging early Microsoft Corporation

Triumph of the Nerds slightly mentions Digital Equipment Corporation / DEC or COMPAQ as later known. DEC is company less known in todays world which had historically great impact on computer market, so its a pity the movie part mentioning DEC is so short.

What the movie misses is to aforemention About’s Digital Equipment VMS operating system known under the code name OpenVMS. OpenVMS even of today is believed by many to be the most secure Operating System ever developed.
The movie part that talks about DEC is the second part of movie it shows a nice COMPAQ portable computer.

DEC Compaq portable II Computer

One should admit COMPAQ portable Computer is a really trendy for its time, Also the way it sticks the keyboard to the screen does remind seriously the opening and closing of a modern laptop 😉

The movie includes some interesting, so called crash courses where the movie author gives some insight on elementary computing, so for those new to informatix the movie will surely be educative as well, though for a UNIX gurus this elementary computing scenes will look kinda ridiculous 😉

One serious flaw with this movie is the complete lack of interviews with Richard Stallman and the importance of Free Software for the development of modern PC and the influence of the free software culture on todays latest Macintosh and PC developments.

A related movie which probably most IT geeks already know / seen is Pirates of the Sillicon Valley
, hence large chunk of Triumph of the Nerds gives another point of view on the ideas and stories presented in Triumph of the Nerds

Triumph of the Nerds brings back some good memories of the glorious PC computer past for all of us who had been a DR-DOS/MS-DOS and Windows 3.11 / 95 users.

Cloud Computing and linode alternatives to a normal dedicated machines

Wednesday, September 30th, 2009

Reading Time: 3minutes
One of the dedicated servers’s harddrive I maintain has failed.
This alone has created many, many problems! It’s serious stuff
since this server is the main mail server and primary DNS.
I still am unsure what is gonna happen. The dedicated server provider
responsible for the server Valueweb ‘s
services complete suck! The situation became even more complex with
the fact that valueweb has been bough by hostway.com
The old server which hardrive has failed needs replacement and is creating
serious problems within the company, however the management solution
required for giving a go to the operation of replacement was postponing
every time I tried to raise the question of the need for server replacement.
Well today the worst has happened. I was woken up by my gsm beepings just
to realize there are 20 smses notifying me that the server is inaccessible.
That happened around 5:30 in the morning! Shit what a miserable life, I only
slept for a couple of hours since I went to bed in 2 o’clock. I tried multiple
times to request reboots of the server all of which doesn’t bringed the system
back. That wasn’t fun really. Right after that I tried to raise a technical support request asking to check the server’s hardware. I never received any responce from valueweb on my
mail to inform me about the status of my request as usual!
Damned valueweb, this stupid bastards ARGHH!. At 9:30 our project manager ringed to ask what’s wrong with the mails.
Well what might it be, a hardware crash.
She had to call to America where the colocation resides, and ask them to move on with the hardware test, otherwise valueweb won’t move their finger.
Of course I was right the system hard drive was broken. And required replacement, after few calls from the office and my quick suggestion to change all
clients smtp and pop3 server to point to the backup server which thanks God at least worked, they did so (Thanks God).
I took the fast decision to come to the office in Varna since I had to talk with the tech support
in Florida and help out to some of the clients to correctly setup the new host in their Thunderbirds
and Outlooks. Yes here you can see how they use me as a tech support as well.
Many websites are down currently, I have spoken a couple of times with Florida’s tech support which were quite arrogant to me.
Never ever use valueweb or hostway as a dedicated server provider seriously this guys are bastards!
My idea was to replace the old server with a new one with a better hardware since it’s already broken, however the company CEO was not keen on the idea again trying to save some money!
You can understand what kind of a “good”CEO he is, since he tries to cut out costs from the hardware, that way guaranteeing again future problems.
He suggested to me to try to migrate to Amazon EC2 (Cloud Computing).
Something impossible since we have specific stuff running on the server
I had to research and assure myself that this Cloud Computing is a bulky shit ass just like I thought well it’s good for stuff like facebook, however in our situation it’s impossible. You can’t simply migrate all the stuff to cloud computing clapping with a magic stick.
In the meantime of researching on the topic I found something inreresting called check out linode here .
As a matter of fact I think it’s a better solution for plain linux install than Debian. Just to complete the post I have to say cloud computing is interesting but it doesn’t stand the same ground as a normal linux install.
A brief funny introduction of Cloud Computing can be seen in youtube’s cloud computing explained . What wikipedia says about Cloud Computing is a nice beginning introduction as well.
Cloud Computing is the latest hype out there is certanly future in Cloud Computing even though I don’t see it to be ready for the masses, yet.
I have to note that it seems the Linux powered Cloud computing options ran a Linux Xen, kernel. I haven’t tested Xen recently but the last time I and a colleague of mine did (2 years ago)
,it seemed back then will be completed to be 100% compliant with the normal linux kernels in the coming 5 years.
However the matter is quite interesting and I have to investigate further in it soon.
Now we decided to solve the situation by purchasing a newer dedicated server. The stupid asses from Hostaway need 24 hours to bring the machine up, you can imagine how insane is that.
In the best case all stuff on the old server would be up and running in the coming 48 hours or even more… ghah
