Welcome to the Age of Digital Transparency.

From the stimulus bill to the Congressional Budget Office's analysis of the cost of the Democrats' health care bill to the "Climate-Gate" e-mails that have raised doubts about global warming, the average American now has unprecedented access to a deluge of information.

Copies of written legislation ... amendments ... government oversight reports ... They're all a click away on the World Wide Web.

"It's now impossible for politicians to hide behind rhetoric when the reality of the information is available to a mass number of people on the Internet" said Richard F. Hanley, graduate director of journalism and interactive communications at Quinnipiac University in Hamden, Conn.

"The idea of speech conveying the detail of information is outmoded, because the speech can be fact-checked by anyone with the Internet," Hanley said.


Not only does the Internet speed the delivery of mass amounts of information to the general public, it also accelerates access to precise parts of legislation. You don't have to sift through a 1,700-page health care reform bill to find details about Medicare beneficiaries. Just type in a few search terms, and the information is right there in front of you.

Government Web sites like Recovery.gov enable citizen activists to track stimulus money -- adding fuel to proponents of the Obama administration's spending while also giving fodder to his opponents, such as the grassroots Tea Party movement, which thrives on data to support its small-government agenda.

For politicians, the Internet is a double-edged sword. Political arguments can b

"Summary

Good disk maintenance requires periodic disk checks. Your best tool is fsck, and should be run at least monthly. Default checks will normally be run after 20 system reboots, but if your system stays up for weeks at a time as mine often does, you'll want to force a check from time to time. Your best bet is performing routine system backups and checking your lost+found directories from time to time. The dumpe2fs utility will provide important information regarding hard disk operating parameters found in the superblock, and badblocks will perform surface checking. Finally, surgical procedures to remove areas grown bad on the disk can be accomplished using debugfs"

This seems to be happening with nVidia graphic cards to fix this problem try to use the following solution i hope this would help

Solution1

I have a HP Pavilion SLimline s7727c

with lspci giving me

VGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2)

I was getting a blank screen (out of sync) on booting from the live cd.

I worked around the problem as follows:

* At install screen press F6 and select nomodeset and install Ubuntu as usual.
* On first boot after install, press e on getting the GRUB bootloader.
* Using arrow keys navigate to and delete quiet and splash and type the word nomodeset in their place
* Press Ctrl and X to boot
* You should now be able to login to your Ubuntu as usual

For those of you who do not know what to do next, in the taskbar click on System->Administration->Hardware drivers, and select and activate the nvidia current driver if you have an nvidia card like I do. The driver will be downloaded and activated automatically, and you will be prompted for a reboot.

Solution 2

Yes, I think you may be right about it being a graphics card problem. I think you may have the same problem that I did on my beat-up old Toshiba Satellite A10.

So, here is what should work:

At the very first screen, the one with just the rectangle (it’s meant to be a keyboard) and a human figure, press any key - spacebar will do.

Then choose your language.

Then make sure you have “Try Ubuntu without any changes” selected, and then press F6

Add this to the end of the command line:

i915.modeset=0 xforcevesa

Then press enter and it should boot successfully.

Solution 3

1. Boot from the Ubuntu 9.10 CD
2. Mount the internal HD and look for /etc/X11/xorg.conf - its missing!
3. Copy a new “known good” xorg.con

Setting up Olsr MESH network with WRT54GS.

Follow the steps in this article to know what you can do!
What to Achieve ?

Freifunk Firmware WRT54Gs to be dispersed, preferably on rooftops with antennas.  These would be connected to VSAT systems and therefore provide a route to the web. Then whoever wants to jump on the mesh, just turns on their machine and connects with normal DHCP to the ad-hoc network supplied by the mesh.

Configuration steps

1. WRT54g's needs to be connected thru the web interface.
2. Upload the Freifunk firmware and reboot the routers
3. Connect on 192.168.1.1 on the browser

This needs to be done on all the routers.

4. Configure the boxes to have same IP addresses, to offer separate blocks of IP addresses to clients, and to maximize the distances they cover.

Here are the settings that needs to be made to the default settings

OLSR
OLSR DHCP: 104.3.2.0/26,255.255.255.192

Wireless
WLAN Protocol: Static
IP Address: 104.3.2.1
Netmask: 255.0.0.0
WLAN Mode: Ad Hoc (Peer to Peer)
ESSID: Lil-Mesh
TX Power: 84
Radio Mode: B Only
Transmission Rate: 1 Megabit/s

LAN
LAN Protocol: Static
LAN IP:192.168.5.1
Netmask: 255.255.255.0
Disable Firewall: Checked

WAN
WAN Protocol: DHCP
Hostname: lil1-wrt54g

The second and third boxes were similar. Differences for the second box:
OLSR
OLSR DHCP: 104.3.2.64/26,255.255.255.192

Wireless
IP Address: 104.3.2.65

LAN
LAN IP:192.168.6.1

WAN
Hostname: lil2-wrt54g

Once this is done power up all the routers.  If you have an internet connection from a DSL modem, or a shared internet connection then plug that into the internet port of one of the WRT54Gs. The mesh will then calculate all of the optimum routes to one another, including routes to the closest internet connection. Now connect your clients to them with either an ethernet cable or with a wireless connection. Finished!

Mystery Surrounds Cyber Missile That Crippled Iran's Nuclear Weapons Ambitions

An aerial view of Iran's nuclear facility in Natanz.
In the 20th century, this would have been a job for James Bond.

The mission: Infiltrate the highly advanced, securely guarded enemy headquarters where scientists in the clutches of an evil master are secretly building a weapon that can destroy the world. Then render that weapon harmless and escape undetected.

But in the 21st century, Bond doesn't get the call. Instead, the job is handled by a suave and very sophisticated secret computer worm, a jumble of code called Stuxnet, which in the last year has not only crippled Iran's nuclear program but has caused a major rethinking of computer security around the globe.

Intelligence agencies, computer security companies and the nuclear industry have been trying to analyze the worm since it was discovered in June by a Belarus-based company that was doing business in Iran. And what they've all found, says Sean McGurk, the Homeland Security Department's acting director of national cyber security and communications integration, is a “game changer.”

The construction of the worm was so advanced, it was “like the arrival of an F-35 into a World War I battlefield,” says Ralph Langner, the computer expert who was the first to sound the alarm about Stuxnet. Others have called it the first “weaponized” computer virus.

Simply put, Stuxnet is an incredibly advanced, undetectable computer worm that took years to construct and was designed to jump from computer to computer until it found the specific, protected control system that it aimed to destroy: Iran’s nuclear enrichment program.

The target was seemingly impenetrable; for security reasons, it lay several stories underground and was not connected to the World Wide Web. And that meant Stuxnet had to act as sort of a computer cruise missile: As it made its passage through a set of unco

Quirks Mode
In the Quirks mode, browsers violate contemporary Web format specifications in order to avoid “breaking” pages authored according to practices that were prevalent in the late 1990s.
Standards Mode
In the Standards mode, browsers try to give conforming documents the specification-wise correct treatment to the extent implemented in a particular browser. HTML5 calls this mode the “no quirks mode.”
Almost Standards Mode
Firefox, Safari, Chrome, Opera (since 7.5) and IE8 also have a mode known as “Almost Standards mode,” that implements the vertical sizing of table cells traditionally and not rigorously according to the CSS2 specification. HTML5 calls this mode the “limited quirks mode.”

Thursday marks 20 years since Linus Torvalds announced on a Web bulletin board that he'd begun working on a free computer operating system. In that message, Torvalds described Linux as "just a hobby, won't be big and professional."

his gadgetry is so small as to be hardly noticeable. In fact, the team insists that it wouldn't be that difficult to make a future version of OmniTouch "the size of a matchbox and as easy to wear as a pendant or a watch."
