hp6735s and ATI display driver in ubuntu

Published on June 14, 2010 in English and it. 0 Comments Tags: , , , , .

Situation:

  • I enjoy using Ubuntu!
  • I enjoy using Ubuntu 9.10 (cos’ I still haven’t upgraded to 10.04)
  • I have hp6735s laptop
  • I use ATI proprietary driver
  • everything is too smoothed on the screen
  • font look like shit
  • windows *** works fine

After digging a little I found out that the problem is:

  • not with the fonts
  • Ubuntu set wrong screen resolution for me: 1280×768
  • right screen resolution 1280×800 is not in the list in System > Parameters > Screen
  • right screen resolution is not available in ATI Catalyst either

Here’s how I fixed it:

  1. run sudo gedit /etc/X11/xorg.conf in terminal
  2. found something like Section "Monitor" ... Option "PreferredMode" "1280x768"
  3. changed 1280×768 to 1280×800
  4. everything works fine after reboot!
  5. compiz and all 3D effects work nice too!
  6. …and hey, it’s the first time I edited xorg.conf by hands!

Enjoy using linux!
That the OS you really need!

Proxy in processing

Published on May 29, 2010 in Creativity, English and Тирнет. 0 Comments Tags: , , , , , .

I’ve been studying processing language, and I think it’s great tool for

  • designers, who want to programmmmm
  • and programmers who want to design

More about it you can read at the official page of the project: processing.org/

If you need to work in processing with internet data && you are behind proxy, it’s a little bit trickier.

Place the following code in your setup() function, and everything gonna be alright!

void setup() {
        size(800,600);

        Properties systemSettings = System.getProperties();
        systemSettings.put("http.proxyHost", "your.proxy.org");
        systemSettings.put("http.proxyPort", "8080");
        System.setProperties(systemSettings);
}

Watch your webcam in console!

Published on January 8, 2010 in Creativity, English, it and Life. 0 Comments Tags: , , , , , , , , .

Wow! I really love linux! I feel that with every minute spent inside linux my love to this OS grows up! It’s so outrageous! You can do almost everything!!!

Today, I was really shocked with the abilities of the mplayer!
Here’s a short video of what I’ve done:

So, here’s a list of what I was doing with it (everything is done in tty-conole->[Ctrl]+[Alt]+[F5]):

  1. I wondered if I can watch films in console. That’s real! You just have to specify the special output driver. It’s the ASCII-Art driver:
    mplayer -vo aa nameOfYourFile.avi
    You can enjoy colour video in console, just replace aa driver with the Colour ASCII-Art driver caca!
  2. I felt it’s not enough! So, I tried to watch my web-cam in console! Obviously, mplayer is able to do it! You just need to specify the tv:// protocol, instead of filename:
    mplayer tv:// -vo caca
  3. Here’s the first problem. The output is alright, but that stats information always updates, and the video is blinking:( So, it makes impossible for you to watch your wab-cam normally. I started to investigate the mplayer’s man page:
    man mplayer
    it’s so huge! (read it if you want :) )
    I quickly found the solution! Here is it: the parameter -really-quiet:
    mplayer tv:// -vo caca -really-quiet
  4. But that was not enough! I wish I can watch the web-cam, as I look at mirror! I found the parameter -flip. But it just turns everything upside-down. The real solution for that is the video-filter Mirror! Specify it & enjoy:
    mplayer tv:// -vo caca -vf mirror -really-quiet
  5. There’s one more improvement, you can do to your output. You can make it better by specifing the font. The smaller the font – the better’s the output. I usually use Uni1-VGA8:
    setfont Uni1-VGA8

That’s all, folks! Go and watch your favourite videos in console!

arp-attacks in our hostel

Published on January 3, 2010 in English, it, University and Тирнет. 0 Comments Tags: , , , , , , .

Happy New Year 2 everyone in this world!
Let al your dreams come true in this 0x7DA year!!!

Right after the NY celebration I wanted to crawl the web & get in touch with my friends. I was really disappointed when I saw our local gateway down…No ping queries were successful:(
I put ping 192.168.1.123 -t and returned to celebration!
At 02 AM ping succeeded!
The situation repeated several times…

But I really wanted to wish best wishes to my mates!
So I started to investigate… The computer was overfilled with ARP-queries :( They changed the real MAC-address of the gateway, so the computer sent packets into wrong place.

The solution is simple:

Make your ARP table entries static!
Under Windows You can do it in the following way:

  1. Run “cmd”; [Start->Run->type “cmd” into it]
  2. type in command line:
    arp -s Gateway.Or.Another.Computer It-s-MAC-Address
  3. For instance if computer’s ip is 192.168.1.123;
  4. It’s MAC-address is 00-11-22-33-44-55;
  5. So you should type into command-line:
    arp -s 192.168.1.123 00-11-22-33-44-55

Best Wishes!!!

8bit Second-hand rush!

Published on December 20, 2009 in Creativity, English and Life. 0 Comments Tags: , , , .

Yesterday my 2 friends & I went to our local second-hand store. We wanted to have some fun &, if we could find smth special & outrageous, we could buy it…

Right at the beginning of the shop we found smth that had blown up our minds!
While surfing all the heaps with closing we saw an old Nintendo-clone: PowerJoy.

Power Joy

Power Joy Nintendo clone

I’ve never seen anything like that… My all childhood was spent with Dendy/Dendy2, which was created in Russia…and was de-facto the standard for game consoles… Almost every child had one!

 

Yeap… we bought it!
It’s awesome!
The only thing you need in order to play is TV.
So the pluses of this console are:

  • it works from batteries – no AC cable needed!
  • main gamepad is the gamepad itself+main computing center+pistol
  • has 9999+ prebuilt games!

As it was bought in second-hand store I had to fix it a bit. There was a problem in battery connection, but I fixed it quickly & was really astonished, when my ears heard the same, known from the earky childhood 8bit noise!!! Then a picture came up!!! That was AWESOME! I quickly found the game, called Tank90 & started fighting with evil tank forces!

It’s really interesting to remember that childish shit… In our days, when people are playing NFS & still complain that they are not satisfied with gameplay or video graphics that 8bit console remembers about the days spent in front of the TV, playing hard & trying to kill all the mushrooms and turtles with the help of Mario&&Luigi…

Genius G-Pen 4500 && Ubuntu 9.10

Published on December 10, 2009 in Creativity, English and it. 12 Comments Tags: , , , , , .

I’m about to use my Genius G-Pen 4500 with Ubuntu. And here is my experience in installing this tablet.

Everything is pretty stright-forward.

  1. Go to http://code.google.com/p/linuxgenius/
  2. Get the source for wizardpen. I used http://linuxgenius.googlecode.com/files/wizardpen-0.7.0-alpha2.tar.gz
    wget http://linuxgenius.googlecode.com/files/wizardpen-0.7.0-alpha2.tar.gz
  3. Unpack.
    tar -xvf wizardpen-0.7.0-alpha2.tar.gz
  4. Move into the unpacked dir:
    cd wizardpen-0.7.0-alpha2
  5. Configure, make and install:
    sudo ./configure --with-xorg-module-dir=/usr/lib/xorg/modules && make && make install
  6. Check for wizardpen.la and wizardpen.so (driver installed correctly):
    ls /usr/lib/xorg/modules/input/wizardpen.*
  7. Connect your tablet (if not yet connected)
  8. Create file /etc/hal/fdi/policy/99-wizardpen.fdi
  9. I used the following data inside the file:
    <?xml version="1.0" encoding="ISO-8859-1" ?>
    <deviceinfo version="0.2">
    <device>
    <!-- This MUST match with the name of your tablet -->
    <match key="info.product" contains="UC-LOGIC Tablet WP5540U">
    <merge key="input.x11_driver" type="string">wizardpen</merge>
    <merge key="input.x11_options.SendCoreEvents" type="string">true</merge>
    <merge key="input.x11_options.TopX" type="string">0</merge>
    <merge key="input.x11_options.TopY" type="string">0</merge>
    <merge key="input.x11_options.TopZ" type="string">40</merge>
    <merge key="input.x11_identifier" type="string">stylus</merge>
    <merge key="input.x11_options.BottomX" type="string">32739</merge>
    <merge key="input.x11_options.BottomY" type="string">32745</merge>
    <merge key="input.x11_options.BottomZ" type="string">1024</merge>
    <merge key="input.x11_options.MaxX" type="string">32739</merge>
    <merge key="input.x11_options.MaxY" type="string">32745</merge>
    </match>
    </device>
    </deviceinfo>

    * This source code was highlighted with Source Code Highlighter.
  10. After all this You should reboot and start using your Genius G-Pen 4500.
  11. FIXED: I still have one unsolved problem. The stylus starts working a bit far from the tablet. Can’t resolve this. Under Windows I found quite unique driver, which let me set sensitivity for it. FIX: Add TopZ and BottomZ values to the file
