I heard that last week the international community was hit by the worst virus attack in the history, this virus was launched by hackers to take over the corporate world. The worm is known with the names of Downadup, Conficker , or Kido -_- it has at least infected 8 million computers most of them were corporate computers. On Tuesday there were 2.5 million, on Wednesday 3.5 million and Friday, 8 million.It's getting worse, not better, right now 8.9 million is the estimated amount of computers infected.
The virus exploits multiple security flaws in Microsoft's Windows OS's. It injects into the system as services.exe, it is a common system process. It creates a new DLL file in Windows system folder with a random five letter name. It makes registry edits referencing this DLL as a service, so it’s automatically run on restart. Once it has its grips on the system, it proceeds to create an HTTP server and download malware onto the computer from hacker web sites. It wipes out the system restore with a reset, making it harder to recover the system. People who think their computer is secures should worry about this worm and should start protecting their computer's by updating their antivirus.
While many viruses download malware remotely from a handful of web sites, the installed files can be easily removed , this one is very hard to remove. This virus creates hundreds of dummy domain names using algorithm coded in the virus, with only one being the actual malware site. This makes it extremely difficult to search what exactly is being installed every single day. The worm's main way to get transferred to another computer is local area network. Once a computer has been infected on the network it searches for other computers on the network, and then it uses the a Windows security flaw to attempt to gain access to them.
While the computers are typically password protected, the amazing part is that the virus can guess short password by a random guessing method which is also known as brute force method. Once it has found the correct password there goes your pc. It infects the next computer and the next one and the next one there's no stopping it . Microsoft has a patch which protects against virus the attack -- MS08-067 --Companies are strongly recommended to get this patch as the virus is rapidly spreading across Europe, the United States, and Asia. The patch may slow the spread of the virus it may not be enough to stop it. The virus has been only used to inject malware into the pc but experts say that hackers could use it on the system to start stealing user's and customer's credit card and personal information.
Microsoft has been providing some special Operating systems to the computer users since Widows 95. After that they developed Windows 98, Windows 2000, Windows Xp (differnt versions) and then Windows Vista.
Now they have introduced another OS named Windows 7, Windows 7 can be considered as Vista with some advanced features and some bug fixes etc.
The following features are prominent and most talked about:
Improved Taskbar
Microsoft is consolidating the various methods of launching programs into a new Windows 7 taskbar, the strip that traditionally appears along the bottom of the computer screen in Windows. The taskbar is larger and offers new ways to quickly interact with programs. For example, a feature calls "Jump Lists" provides a quick glimpse of recent files and features associated with a particular program when a user right-clicks on the program's icon in the taskbar. So, it makes the things quicker than before.
taskBetter and easy search
The new Windows 7 search function will provide a unified method of searching USB drives, external hard drives and other computers on a home network, from one centralized location.
Window management
Dragging an open window against the left or right border of the desktop automatically resizes it to fit one half of the screen. That makes it easier to quickly adjust the size of two windows -- for cutting and pasting text between documents, for example. Likewise, dragging a window on the top border of the desktop quickly expands it to the full size of the screen.
System Tray
Officially known as the “Notification Area,” Microsoft finally give users the tools to address the desktop area, which is often disorganized. Users can have any icon that is displayed in the System Tray, the icon to change the position and whether it is allowed to attract users with the notification.

Home Groups
Windows 7 is to introduce a new feature called Home Groups network that aims to ease some of the computer network to share files and peripherals - as if all that is located on a PC the same. Although the features of Windows Networking since always aims the same, In fact configuration to use the network printer is still too difficult for most users.
Peeking
Peeking features in Windows 7 are easier for users to quickly read the content in one window without the need to interact with the other window. Placing mouse over the thumbnail window on the Task Bar will change all open windows except for a transparent window is selected. In addition to “snoop” window applications, users can also tout the Windows desktop.

Multimedia Streaming
W7 add features delivery media files from PC to the various tools that support streaming music such as the Sonos system through the network. Microsoft said that the W7 will change to the file in a format that can be played by your media player.
play-to
Themes
In W7 Microsoft provides a new theme that suits better with the preview feature in the original size and allow you to save custom themes with just a few clicks. Microsoft also plans to change Themes Styles.

Nice Paint
Windows Paint is to get big upgrade, now appearing with the Ribbon UI of Office 2007 that has now become standard in many Microsoft applications.

Touch Screen
Windows 7 is the first version of Windows that supports multi-touch that allows you to control the OS with both hands. Many still doubt whether the multi-touch will change the PC world as it changed world’s mobile phone. Currently there are almost no PC outstanding in the market that supports features touch screen other than the Touch Smart from HP and Dell Latitude XT.
These features present in the beta version can rate the Windows 7 as a better windows than the previous version, But again OS like linux still have their own roll.
Rumors are their about its official release in 2009,but the expected release date of this OS is in mid of 2010.
Last night i was searching for few topics about hacking as it is the topic of my presentation tomorrow, but i was surprised to see that every link in the search results had a warning message under it " This site may harm your computer".
At that time I could,nt know that this was actually a hiccup at google's end as i was in hurry to get my work done as early as possible.
I am sure some of you guys also have been through this as all the blogosphere is abuzz about the complaints given by the unhappy web surfers.
The problem appears to be centered around the google safe browsing API even that returned a “This site may harm your computer” warning , the security diagnostics service that powers Firefox’s malware blocking service.
This Screen shot tells all :
google_safebrowsing1I wonder how much this episode has damaged the reputation of the google but its still too early for us speculating anything about reputation right ?
Day One: January 21
Barack Obama entered the Oval Office to find a note marked “44” written by his predecessor, George W. Bush. He then spent the day planning to push his $800 billion stimulus package in the house and senate. His first phone calls as president were made to leaders in the Arab world. He also placed limits on lobbyists and froze the salaries of White House employees making more than $100,000 a year as a gesture to stop frivolous spending in Washington.
Day Two: January 22
HIs second day was spent marking a strong departure from many of President Bush’s policies. President Obama signed an executive order stating that the prison at Guantanamo Bay would be closed within the year. He also ordered the closings of secret CIA “ghost prisons” and the cessation of advanced interrogation techniques. In addition, George Mitchell was assigned special Middle East envoy to help tackle the strife in Gaza.
Day Three: January 23
President Obama reversed a policy that restricted federal aid to be delivered to organisations that promote or provide abortions overseas. George Bush reversed Clinton’s similar policy 8 years prior. The president nominated former defence lobbyist William Lynn as Deputy Secretary of Defense as unmanned American drones killed 18 in a series of missile attacks on the Pakistani side of the Pakistan-Afghanistan border.
Day Four: January 24
On the first Saturday of his presidency, President Obama delivered his first radio address. In keeping with the internet strategy used during his campaign, the address was posted as an online video. He stressed the importance of his stimulus bill and the urgency at which it needed to be passed
Day Five: January 25
While Republicans voiced their opposition to his stimulus plan, the president spent the day with his family.
Day Six: January 26
President Obama allowed states like California to decide their own emissions and fuel efficiency standards. The President also gave his first television interview as president with Dubai-based al-Aribiya. He used the interview to stress to the Muslim world his empathy and diplomatic intentions.
Day Seven: January 27
President Obama met with high-ranking republicans to discuss his $800b bail-out package. They viewed it with extreme scepticism.
Day Eight: January 28
The President had his first visit to the Pentagon to speak with Defense Secretary Robert Gates about US planning in Iraq and Afghanistan. Later, he delivered another speech detailing the urgency at which the economy needs be handled-specifically through his stimulus bill. President Obama invited ten senators (five democrats, five republicans) and twelve congressmen (six democrats, six republicans) to a cocktail party to discuss the stimulus plan.
Day Nine: January 29
The president and his wife began the day by attending a class presentation at daughter Sasha’s school. He then approved an equal-pay legislation dubbed “Ledbetter’s Law.” It was the first bill he signed into law. President Bush had previously opposed the legislation. His stimulus bill passed through the house without a single republican vote.
Day Ten: January 30
At the ten day mark, President Obama created a middle class working families task force to be headed by Vice President Joe Biden. He also signed a series of pro-union executive orders. The President received help from union workers during the campaign and subsequent election, and he looked to reverse President Bush’s policies that were perceived by some as anti-union.
PARTS OF MICROSCOPE AND ITS USE: COMPOUND MICROSCOPE
0 comments Posted by FAKHAR ALI (FAB13) at 10:26 AM Place your microscope on a secure table, free from vibration, to begin. Try to have the microscope at least one foot away from any edge to avoid an accidental fall. Turn on your illumination, if so equipped, or, if mirror equipped, turn the microscope toward the best available light source and tilt the mirror, as you look through the eyepiece, until the brightest possible light shows through.
Select the proper objective for the magnification you desire by rotating the turret or nosepiece such that the objective is in alignment with the eyepiece. Place your slide on the stage and secure it with the stage clips, or with a mechanical stage, if so equipped. Try to align the specimen as near to the center of where the objective will come down. This will make it easier to locate when viewing through the eyepiece. Before looking through the eyepiece, turn the coarse focus knob, which will lower the objective, until the objective is almost in contact with the slide. The purpose for this is simple. As you turn the coarse focus knob, your specimen will come into focus.
Most microscopes are equipped with a diaphragm of some sort. This is located directly below the stage, but above the light source. Usually diaphragms are of two types: a disc diaphragm (a disc pre-drilled with holes, from smaller to larger, that you dial in the appropriate light) or a better choice, the iris diaphragm (which, like a camera lens, offer unlimited adjustment). Depending upon your specimen, more light or less light may be required for the best viewing. In conjunction with the diaphragm is the Abbe condenser that further focuses the light through another lens before it reaches the objective. An additional option is the adjustable Abbe condenser, which allows movement of the condenser below the stage of about one half inch. Again, it depends on your specimen as to how much or how little light is required.
Once you have focused with a particular magnification, you will want to view the specimen under different magnifications. Simply rotate the nosepiece until the objective you require is in line with the eyepiece.
SOCCER VS CRICKET
SOCCER IS the BEST
Everyone should watch and play the soccer because of the following reasons. The First reason is that it does not take too much time as compared to the cricket. Mostly people like the games which can be playing and enjoying for short time. Therefore, there are around 40 to 50 million people in the soccer ground. The Second reason is that it is full of entertaining for people. In short time period, it has a lot of action in the soccer ground so; it is not possible to go away from TV for a second. The third reason is that there are fewer chances for players to get injury in soccer game and we use hardball in cricket and it is harmful for players. There are many bowlers who have proved themselves that they are very dangerous for the batsman like Shoaib Akhtar, Brett Lee, and Mohammad Zahid. Many people might say that in cricket twenty over match is also very entertaining for people but I believe that soccer is more entertaining, more interesting game than the cricket.
