Skype in Ubuntu couldn't see my Microsoft VX-7000 webcam

My VX-7000 works fine with Cheese, but not in Skype. I'm not sure any of the stuff in part 2 is necessary, but typing the command in part 1 below, in terminal mode, instantly started Skype and the Video:

1. Since your camera is recognized by ubuntu. So may the famous command:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

Of course you don't want to type this every time you use skype, so make a script that runs when you type ./skypescript.sh in the terminal. Then paste the ./skypescript.sh into your desktop LAUNCHER and you are done.
To prepare the script place this follow the instructions in this link but replace the script with this one:
#!/bin/sh
sudo modprobe -r uvcvideo
sudo modprobe uvcvideo
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

This script loads the driver and preloads stuff, then runs Skype.
Next, run this command to make the file executable:
chmod 777 samplescript.sh
and you are in business.

2. The mess below, was very busy, but did not succeed. Installing the drivers for the webcam. Not child's play.

install subversion

Code:
sudo apt-get install subversion
get uvc svn version

Code:
svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
get kernel header

Code:
sudo apt-get install linux-headers-`uname -r`

in the uvc MAKEFILE

change

Code:
INSTALL_MOD_DIR := usb/media to  INSTALL_MOD_DIR := ubuntu/media/usbvideo
compile and install

Code:
make && make install
load the module

Code:
sudo modprobe -r uvcvideo  
sudo modprobe uvcvideo

Yay!

I set up a crude Ubuntu server at home with 2 drives, and read the files over the network to a windows PC.

Installed on My Ubuntu Server
  1. Samba (right click in Putty to paste text from a webpage to the server command line)
  2. vsFTPd Alternative instructions Quick FTP Server Setup

Configuring an Ubuntu Home File Server

The idea is to dedicate an old PC to file service and keep all the Workstations around the house as basic as possible. That way they can crash and do all the ugly things experiments cause without fear of damaging my documents.

I've discovered that Windows users should leave now; Linux/Ubuntu servers are command line driven and the help is nasty looking at that.

Discouraged? Read why you like Ubuntu below. Good luck.

Tips to add a Desktop to Ubuntu server

This will install everything, needs 2.1 GB of space
  • sudo apt-get install ubuntu-desktop
    (the bare version is called gnome-desktop and uses 500 MB) (can take up to 1 hour)
  • sudo apt-get install gdm
  • sudo /etc/init.d/gdm start
  • sudo dpkg-reconfigure xserver-xorg
  • you may need to provide the screen resolution 800x600
Source: http://ubuntuforums.org/archive/index.php/t-186298.html

Testing only:
Leaving the server alone, I'm trying first install Perl then Webmin from my Windows PC.

Safe banking for tech savvy users?

I'm trying it out. For tricky transactions, boot from la Linux CD and remove it when you are done.
I'm not having fun yet, the passwords prove to be tricky. More to follow.

My PC - My Personal Computer

Rebuilding my HP m7070n with the 3 DVDs I just received within 12 hours of ordering them online.
It took 5 hours from pressing F10 to restore to accessing the Internet. Thankfully, there is almost no intervention required, just let it copy from the DVDs to the fresh hard disk.
I have this 200 GB drive so it will be my new C: since it will only record TV shows and access the Internet I want the machine to run at top speed. I deleted most of the toy software that comes with the new machine.
I am installing the following applications in this order:
  1. AVAST Free anti-virus
  2. Brother MFC-7840W LAN Wireless Laser Printer driver

  11. Dropbox - Home - Secure backup, sync and sharing
  12. Virtual drive vdcx
  13. Quicktime
  14. Itunes
  15. SketchUp 7.1
  16. Google Earth
  17. Google Chrome FRAME for IE
  18. Linux as an application Ubuntu 9.10 (Karmic Koala) Beta Download: PC (Intel x86) desktop CD
  19. Evernote for Windows
  20. WinRAR (32-bit) - Free

The end of an era?

The future. Don't be too happy with Microsoft's demise. As teachers we have had it easy teaching one operating system, one application suite. No giant is displacing Microsoft, but hundreds of smaller players are tearing off their shares of the market. 
We don't have to take them seriously right now, but our clients will slowly introduce a wide variety of software into offices. So the school of 2010 might be expected to handle : 
  1. Microsoft : Windows 7 & Vista, Office (Word, Excel, PowerPoint, Access) OpenOffice 
  2. Microsoft : live.com
  3. Apple : OS 10.x For those who put a premium on user productivity, MacOS X is the no brainer option more
  4. Linux: ubuntu, openSuse. For those who put a premium on cost savings, Linux is the no brainer option: it runs on cheaper hardware and you get it for free or nearly free and with, or without, paid support. more
  5. Google: Chrome OS (Just replace OS when you read browser. Notice the little reference to running in machine code (p15). SE) Software_as_a_service Docs.google.com It runs on the same WEBKIT used for the Iphone and the Mac Safari browser, could it soon be the OS of an entire GOOGLE PC ? more...
  6. Yahoo: maybe not
Feed the rumor mill: FREE GOOGLE PC

As long as you're giving away software, why not hand over the whole box?

The argument: Computer hardware prices are plummeting in any case. Experts say Google may one day start giving away PCs, reducing them to the equivalent of the free calculator you get when you open a bank account. The Google PC would come loaded with ad-supported software designed to keep people Googling - and not necessarily doing their work.

A recent study by the Nielsen Norman Group found that employees spend 11 seconds a day, on average, glancing at ads surrounding free software. Clicking on ads wastes another 15 seconds a day. These are tiny increments of time, but they add up. Over a year, Nielsen Norman estimates, a free computer could easily cost a company $100 an employee in lost productivity.

Another new frontier for Google is cellphones. Already the company is delivering services such as traffic updates to phone screens. Many analysts expect Google to team up with a cellular service provider such asSprint (Charts) or Cingular to offer a mobile pricing tool.

Cellphones already have cameras, goes the reasoning. So why not add a bar-code scanner? You could walk into an electronics store and scan a DVD player. Up would pop the price, along with Google ads for various area merchants, touting their lower prices on the very same item. "This is a logical direction for Google," says Roger Entner, a telecom analyst in the Boston office of Ovum, a research firm. "It would extend their advertising reach out onto the actual floors of merchants."

Or what if Google offered a certified same-day international digital document-delivery service? That's eminently doable, given Google's massive server farm. America's entrepreneurs would turn cartwheels in their Dockers if Google figured out a way to beat FedEx (Charts) and other couriers on both price and speed.

Or what about an e-mail translation service? Simply send an English e-mail to your Chinese supplier via google.chinese.com. Google would translate the message into Chinese and forward it to the addressee - in real time.

If nothing else, expect Google to continue challenging established ways of doing business. For good and ill, Google is one of the most awesome forces ever to be unleashed on the business world - or rather the Google world in which all business owners now live. More

Excerpt: My guess is Steve Ballmer is working on a combined answer, one that is sketched before our very eyes already. Microsoft's Live services are but a rehearsal for a much bigger act, Microsoft's Cloud OS, sometimes calledStrata. And, based on Microsoft's own Cloud services, we'll see a Danger-based smartphone, as proprietary as the Xbox and the iPod competitor Zune. Put another way, Microsoft's future business model will borrow from Apple and Google, it will have two components: proprietary devices and "universal" Cloud services. And like its models, it will attempt to extract extra profits by nicely tying both components together. For example: iPods are tied to the iTunes service, Android phones might (we don't know yet) better enjoy Google applications.
