Since the introduction of google maps streets view two days ago, people are going crazy in trying to zoom in and find hidden gems in those captured images. If you don’t know about this click on the link above and you’ll see what I’m talking about, or you can just go to maps.google.com and zoom down to street level in either NYC or San Francisco and push the new Street View button (top right corner of the map). Really cool and well–atleast according to some on the net–Scary!!! So the question is:

Do we need someway of telling the google van that we don’t want to be in their photographs? Judge for yourselves….

How to use a custom DNS name with blogger

datePosted on 10:55, May 31st, 2007 by Many Ayromlou

So I finally broke down and registered nerdlogger.com with easydns.com. I’ve used their service for my own ayromlou.ca canadian domain, so I figured, why not. Under ayromlou.ca I was doing all kinds of redirects to get www.ayromlou.ca to point to nerdlogger.blogspot.com (which is the standard addressing scheme for blogs on blogger). Now, here is how I got my custom domain name (nerdlogger.com) to work:

  1. Obviously first register your domain name. I went over to easydns.ca (.com is the same company) and registered nerdlogger.com (I use the DNS-Only service & Registry Fees)
  2. Give them about 2-4 hours to propagate the DNS information. Do not change anything during this time.
  3. Now after about 4 hours go back and login. You should see the Members page and somewhere in there there should be a listing of the domains you own under domain settings. Click the DNS command next to the domain you want to use and you should see a page with a bunch of stuff relating to your brand new domain.
  4. Scroll down to hosts section and delete all the predefined hosts (click the check box next to them and delete).
  5. Now on that same page (you might have to navigate back to it from the members page) under aliases setup a CNAME (alias) for www with the corresponding A Record (host) for ghs.google.com and press next to submit it. Make sure it says www only and ghs.google.com and nothing else.
  6. Now you have to wait another couple of hours for the new information to propagate.
  7. Log back into your easydns account and check the domain information page it should have a CNAME (alias) for www.yoursite.com. (Note the terminating DOT) and a Point to A Record (host) of ghs.google.com. (Note the terminating DOT).
  8. Now log into your blogger account and switch to the settings page. Look under publishing tab and select Switch to: Custom Domain. Fill the Your Domain field with www.yoursite.com and press Save Settings.
  9. Wait another 10 minutes and try going to http://www.yoursite.com and/or http://yoursite.com. Both should work at this point.

YouTube….Better!!!

datePosted on 23:58, May 29th, 2007 by Many Ayromlou

Okay just came across Stage6…..and one word….WOW. I think we finally have something that will compete directly with TV (SD or HD) that is actually flexible enough for artists to create custom frame sizes in (think 2.35 aspect for your youtube movies with divx codec). Very nice…..

Check it out at:

http://stage6.divx.com/

Okay this was relatively simple…..

  1. Make sure you can either ssh and become root and/or run xterm and become root on your N800.
  2. Ssh to the N800 and become root (either through sudo grainroot or something similar)
  3. Goto kbdd‘s website and download kbdd.tar.gz onto your N800.
  4. Extract it to root’s home directory using tar -zvlf kbdd.tar.gz and cd to kbdd.
  5. Unfold the keyboard/insert battries/press the button on top right corner and make sure the LED beside it starts blinking.
  6. In Ssh client type hcitool scan to scan for bluetooth devices. If you have more than 1 device you might see multiple entries. Note the Bluetooth address in form of xx:xx:xx:xx:xx:xx . You will need this in the next step.
  7. Use vi (in ssh session) to edit the file btkbd.conf and make it look as follows:
  8. BDADDR="xx:xx:xx:xx:xx:xx"
    KBTYPE=btfoldable
    PORTNUM=2

  9. Where xx:xx:xx:xx:xx:xx is the Bluetooth Address you got at step 6 and PORTNUM is the Bluetooth serial port number the script creates (2 should be safe, try not to use 0/1 as they are used for Cell phone connections).
  10. Make sure your Keyboard and N800 are not paired before starting this process. If they are paired, delete the pairing first. Make keyboard discoverable (press the top right button beside the LED) and run btkbd command from ssh command line. Wait for a pop-up on your N800 and type 0000 as the pairing code.
  11. If everything is working you should be able to type on the BT keyboard now. You can run btkbd again to stop the deamon.
  12. If it works you can add menu shortcut. Just run the install_shortcut.sh script in kbdd directory.

Streaming DV with VLC in Linux…..

datePosted on 15:01, May 28th, 2007 by Many Ayromlou

Thought this might be useful for someone:

Install the libraw1394 and libavc1394

If you want to be able to stream from a DV camcorder, then you need to install the libraries libraw1394 and libavc1394:

If you use a Fedora Core distribution then you just need to install the libraries using:

%yum update
%yum install libraw1394 libavc1394

If you want to install the libraries from the source then you must download them from the libraw1394 and libavc1394 from their projects website. If you have a distribution that uses udev, then you must add/change the following line to the file 50-udev.rules in your /etc/udev/rules.d directory.

%vi /etc/udev/rules.d/50-udev.rules
# IEEE1394 (firewire) devices (must be before raw devices below)
KERNEL==”raw1394″, NAME=”%k”
KERNEL==”dv1394″, NAME=”dv1394/%k”
KERNEL==”video1394*”, NAME=”video1394/%n”

The following sections assume that you have a working linux installation with the IEEE 1394 (Firewire) libraries installed, either manually from the source code or through your distributions upgrade mechanism.

Stream with DV

Connect the DV camcorder with a Firewire cable to your computer, and check the creation of the file /dev/raw1394.

Run VLC with the following command line :

% vlc -vvv dv/rawdv:///dev/raw1394 -dv-caching 10000 –sout ‘#transcode{vcodec=WMV2,vb=512,scale=1,acodec=mp3,ab=192,channels=2}:std{access=mmsh,mux=asfh,url=:8080}’ –sout-transcode-fps=25.0

where:

  • dv/rawdv:// is the DV input and /dev/raw1394 the device file
  • dv-caching is the delay is miliseconds (ms) (start with a high value, 10s or so, and lower it later)
  • sout is the stream output chain that is used to stream the DV camcorder as a multimedia stream over the network. The transcode syntax is explained in the chapter about transcoding. The example as given above generates a multimedia stream that is compatible with Windows Media Player
  • sout-transcode-fps is the number of pictures per second 25.0 that the transcode module should generate of the requested audio/video codec.
