Locate your Stolen Laptop.

Computer Science, IT NEWS, Recent News, Rishav's Personal

Ever faced with a situation wherein you were trying all measures to get back you stolen laptop or PC? LocatePC comes to your rescue.

The software runs unobtrusively on your computer, with no icons, popups or saved emails. And the thief who has stolen your laptop, will not even know that LocatePC is running. As soon as the thief connects it to the Internet, it gives out a message to the mail id you have provided thus helping you map out your laptop. Working with LocatePC is simple. We will guide you here on how to install and work with this software.

The software runs on Windows Vista/XP/Me/98. Log in to your system and connect it to Internet. Remember LocatePC does not support HTTP proxy servers, mail servers that use SSL or SPA or IMAP (including Gmail and Hotmail), or email accounts that only work when the PC is connected to a specific ISP. Download the software from http://www.iconico.com/locatePC/index.aspx and install it.

Configure you email by clicking on “Settings” in the main “Console” menu. You need a POP email account for LocatePC to send you email. You can create one from AOL, Gawab, Bluebottle or @inMail24. Next, click on “Email message” under “Settings” menu and enter the mail id which is not your regular one, you can use your friend’s id.

Now go to “Email schedule” and set when you want to get an alert from LocatePC. The “Settings” menu also has an “Advanced” menu, that you shouldn’t normally need to change. It includes options such as, trace route, show reported IP address, etc. Now try an IP change. You will be greeted with an email with informationlike the IP address of the thief.

Reducing the Electricity Usage in the Datacenters

Computer Science, IT NEWS, Rishav's Personal

In the past, it would have been considered ridiculous for somebody to say that datacenters should be moved to polar regions to be kept cool. But today, with the size and magnitude of computing increasing explosively, such options are vehemently considered for future datacenter needs. As almost 50 percent of the power that reached a datacenter is consumed for cooling the device, a control on this will help reduce the energy consumption significantly, especially as the industry is talking about green IT with an unprecedented enthusiasm.

Experts suggest that massive measures have to be taken to cut down electric power, which is needed for cooling these data centers.

According to Ramkumar Kothandaraman, Director of Microsoft Technology Center, an option is to utilize gifts of nature like wind chilling seasons. While participating in a panel discussion at Great CIO conference in Bangalore, he referred to Microsoft’s datacenter in Chicago that lets cold wind inside to cool the device and does not consume any amount of energy for its cooling purpose.

Earlier, San Francisco based Advanced Data Centers, an owner and operator of datacenters, had announced that it had opened a 41,000 square foot datacenter outside Sacramento, where the nights are cool, and hence help chill the device.

ADC’s McClellan datacenter, a 15-foot high, 100-foot long section of the datacenter lets outside air into the device to cool it when the temperature conditions are right. And because of the temperate weather in the Sacramento area, outside air can cool this datacenter 75 percent of the time.

Another technology advancement that has already happened in this area is a fusion of sensor networks and virtualization that helps keep several datacenters connected to each other. The system also facilitates a communication between datacenters in the network. The sensors installed around each datacenter grasp signals when a device in a network over heats, and then they send signals to stop processes in that device and shift all its computing activities to another datacenter that remains cool in the same network. Such timely interventions by sensors make sure that no datacenter ‘massively’ consumes electricity to cool it.

Consider Jammu and Kashmir, the northern state of the Indian union with two capitals. The state activities are based in Jammu during winter and in Srinagar during summer due to extreme temperature variations. This means even inhabited regions of India have such extreme temperature variations. So, why can’t we utilize the geographical features of the country to green the IT sector by setting up datacenters in different areas and keep them networked, and thereby keep on shifting computing processes to one after the other devices as weather varies?

Your web Searches harm Envoirnment a lot

Computer Science, IT NEWS

Though technology has greatly contributed to the advancement of human life, the same badly impacts the environment. The case is not different in terms of website search also as a single Google search generates about 7 g of carbon dioxide. As more than 200 million people are estimated to search internet everyday, the effect would be serious as it increases electricity consumption and green house gas emission.”Google operates huge data centers around the world that consume a great deal of power and Google search has a definite impact on environment,” opined Alex Wissner, a Harvard University physicist, whose is about to conclude a research on the environmental impact of computing.

However, Google is keeping silent about its energy consumption and carbon footprint. The locations of dozens of its data centers are also unknown.

According to a recent Gartner study, the global IT industry generated as much greenhouse gas as the world’s airlines, which is about two percent of global carbon dioxide emissions. “Data centers are among the most energy-intensive facilities imaginable,” said Evan Mills, a scientist at the Lawrence Berkeley National Laboratory in California.

Google’s search engines generate high levels of carbon dioxide because of the way it operates. For instance, when we type something in a Google search for information, our request doesn’t go to just one server, instead it goes several ones competing against each other. Google takes data from whichever products that answer fastest. Though the system minimizes delay, it increases energy consumption. Google has servers in U.S., Europe, Japan and china.

As per the Mills’ research, viewing a simple website page generates about 0.02 g of carbon dioxide per second. This rises about tenfold to about 0.2g of carbon dioxide a second when viewing a website with complex images, animations or videos.

Increase your cable modem or DSL speed in XP

Computer Science, Tips an Tricks

This tweak is for broad band cable connections on stand alone machines with winXP professional version – might work on Home version also. It will probably work with networked machines as well but I haven’t tried it in that configuration. This is for windows XP only, it does not work on win2000.
I use 3 Com cards so I don’t know how it works on others at this point. It does not involve editing the registry. This tweak assumes that you have let winXP create a connection on install for your cable modem/NIC combination and that your connection has tcp/ip – QoS – file and print sharing – and client for microsoft networks , only, installed. It also assumes that winxp will detect your NIC and has in-box drivers for it. If it doesn’t do not try this.
In the “My Network Places” properties (right click on the desktop icon and choose properties), highlight the connection then at the menu bar choose “Advanced” then “Advanced Settings”. Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK

  1. From the windows XP cd in the support directory from the support cab, extract the file netcap.exe and place it in a directory on your hard drive or even in the root of your C:\ drive.
  2. next, open up a command prompt window and change directories to where you put netcap.exe. then type “netcap/?”. It will list some commands that are available for netcap and a netmon driver will be installed. At the bottom you will see your adapters. You should see two of them if using a 3Com card. One will be for LAN and the other will be for WAN something or other.
  3. Next type “netcap/Remove”. This will remove the netmon driver.
  4. Open up control panel / system / dev man and look at your network adapters. You should now see two of them and one will have a yellow ! on it. Right click on the one without the yellow ! and choose uninstall. YES! you are uninstalling your network adapter, continue with the uninstall. Do not restart yet.
  5. Check your connection properties to make sure that no connection exists. If you get a wizard just cancel out of it.
  6. Now re-start the machine.
  7. After re-start go to your connection properties again and you should have a new connection called “Local area connection 2″. highlight the connection then at the menu bar choose “Advanced” then “Advanced Settings”. Uncheck the two boxes in the lower half for the bindings for File and Printer sharing and Client for MS networks. Click OK.
  8. Choose connection properties and uncheck the “QOS” box
  9. Re-start the machine
  10. after restart enjoy the increased responsivness of IE, faster page loading, and a connection speed boost.

Why it works, it seems that windows XP, in its zeal to make sure every base is covered installs two seperate versions of the NIC card. One you do not normally see in any properties. Remember the “netcap/?” command above showing two different adapters? The LAN one is the one you see. The invisible one loads everything down and its like your running two separate cards together, sharing a connection among two cards, this method breaks this “bond” and allows the NIC to run un-hindered.

What is the CAPTCHA project?

Computer Science, Rishav's Personal

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is trademarked by Carnegie Mellon University. The term CAPTCHA was coined in 2000 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper (all of Carnegie Mellon University), and John Langford.
A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions from spam, bots – automated scripts that harvest email address from publicly available web forms.
A simple CAPTCHA had been developed in 1995 by Anton Lam of The Chinese University of Hong Kong, in a voting application written for Radio Television Hong Kong. Other primitive CAPTCHAs seem to have been later developed in 1997 at AltaVista by Andrei Broder and his colleagues to prevent bots from adding URLs to their search engine. In 2000, Luis von Ahn and Blum developed and publicized the notion of a CAPTCHA, which included any program that can distinguish humans from computers. They invented multiple examples of CAPTCHAs, including the first CAPTCHAs to be widely used (at Yahoo!).

Making your WI-FI connection secure.

Computer Science, Rishav's Personal, Tips an Tricks

Wireless Internet access in homes and offices has emerged as the easiest option for terrorists to abuse. After Ahmedabad blasts, in which WiFi system of an American resident in Mumbai Ken Haywood was hijacked to send the terror mail, they used the wireless network of a firm Kamran Power Control to send their sinister mail about Delhi blasts to media.

In both the cases, the users had not secured their WiFi networks. Wireless Internet access is a huge convenience that we have got used to, but it is important to secure them. Most Internet users do not even realise that connecting their system to Web through WiFi routers can make them more vulnerable to hackers.

Here are some simple ways to secure your WiFi network and prevent its misuse.

1. The first thing to do to make your wireless network secure is to access Internet through a password protected router be it home or office. Every router comes pre-configured with a standard password, and hackers know this. This makes it very easy for hackers to simply gain access into your network, gain control over its administrative rights and use your network and computer the way they want. Wardriving, in which any person within the peripheral reach of your router’s wireless signal (between 20 to 100 metres) can simply stand outside your premises in a car or on a bike and send a terror mail by using a laptop or handheld device.

2. To prevent this, a password must be fed at the time of setting up the router and connecting it with the DSL. This password can be written down and kept with you, and inserted each time when your system asks for it before connecting you to Internet. The large WiFi systems at most airports, hospitals, enterprises, or educational and scientific institutions, are password protected. Such access control is intended not only at revenue collection, but also security of the system. There is no reason why individuals or small organisations should not follow the same principle as a misuse of their IP — be it for sending out pernicious mails or hacking other’s computers — can make them liable to be accused by the police. If you do not know how or where to put the password, call up your service provider and insist that the engineer puts in the password in front of you. Ensure this each time you change the settings, or your machine and hand-helds. Similarly, auto logins may be a great convenience, but are a taboo from security perspective.

3. Change this administrator password on the router from time to time like you should change any other password so as to minimise the risk to your network. How you change your password varies from router to router. There are several sites on the Net (even sites of the company that owns the brand of router you use) which will tell you how to go about changing the password of your router. If the task is still insurmountable, call up your ISP to understand the process. But remember not to have a wireless network without password.

4. SSID is defined as the name of a wireless local area network (WLAN). Your network router sends this out. If someone knows your SSID, it makes it easier for him to connect to your router. If you turn off SSID broadcasting, you can keep casual users away from seeing your network. However, just doing that would not solve the problem. As even if you stop broadcasting your network’s name, people might still be able to connect to your network as manufacturers generally ship their wireless routers with the same generic SSID. To improve the security of your home wireless network, change the SSID to a different name than the default like your unique name.

5. One of the best ways to secure your WiFi network is through encryption. There are primarily two encryption WiFi standards — Wireless Equivalent Protocol (WEP) and WiFi Protected Access (WPA).
Wired Equivalent Privacy (WEP) is the original wireless encryption standard, which is now outdated. The main problem with it is that it can be easily “cracked.” Cracking a wireless network means defeating the encryption so that you can establish a connection without being invited. A 128-bit WEP is an updated, more secure version of the original WEP. However, skilled attackers can still crack 128-bit WEP in a few hours or less, giving them access to your network.

6. WPA-PSK (also known as WPA-Personal) is a more secure alternative to WEP. However, since it is newer, it is not as widely supported. However, if you have wireless devices that don’t support WPA, such as media extenders or wireless cameras, you will have to use WEP on your network instead.
You might also see the security method called WPA-Enterprise. As the name suggests, this method of network encryption is designed for business use. Setup for WPA-Enterprise is more complex than for other types of encryption, and it requires special network infrastructure. The newest type of wireless encryption, WPA2 provides the highest level of encryption available. WPA2 encryption should be your first choice if your wireless router — and all of your wireless computers and devices — support it. Also, remember, if you use WEP encryption, change your encryption key once a month. So even if someone manages to learn your key, they will be locked out again when you change it.

7. A very simple tip which goes a long way is to turn off your network when not using it. All you need to do is to just turn off your router when you are not using your network. Remember, the lesser time your wireless network is on, the less are the chances of it being hacked. So, switch it on only when needed and then switch it off. Treat WLANs as untrusted networks. Always remember to check your network to see if intruders have made their way in. There are several free programmes available on the Net which will help you monitor wireless monitors.

Changing the Location for My Documents in Windows XP

Computer Science, Rishav's Personal, Tips an Tricks

Hard disk getting full? Time to change My Documents location on your system.There are a number of reasons why you may want to change the physical location where the content of the “My Documents” folder is stored on your computer. Most people don’t know that it only takes about 30 seconds to change the physical storage location of the “My Documents” folder on their system.

You simply wouldn’t believe how many people lose time and valuable files trying to clean out files they no longer need in order to free up disk space when they run into this problem. Be smarter. Use this one little tip and give all your programs the disk space they need. So many people get frustrated because they upgraded their computer with a second hard drive and they just don’t understand why they still run into disk space problems. That’s because Windows was initially installed on their original hard disk. When given a new hard disk with extra space, Windows isn’t smart enough to recognize this extra storage automatically. This little “Change My Documents Location” trick will simply help Windows make better use of your hard drive capacity. While I wholeheartedly agree that it’s not a very good idea to run Windows on a system with only 383MB free space on the system disk, the point that I’m trying to drive home here is that this is a very common problem. Follow the steps below to get the solution.

1. Click on the Start button

2. Right-click the “My Documents” folder and select “Properties”

3. Windows will open up the My Documents properties window:

4. Click on the “Move” button and browse to a location on your other hard disk

5. Click ok

6. Windows will aks if you want to move the current files in your “old” My Documents folder to the new location. Select “Yes”.

7. You might get additional dialogs about moving read-only files or system files. Confirm those as well

8. That’s it! That’s all you need to do to move your “My Documents” folder to a location with more breathing room. Provided that you have an additional hard disk with extra space of course.
