Google "Not" operator

Whenever we are searching with google for something, lots of irrelevant stuff also comes up.
For example,if i am searching for something related to vb.net, all things related to asp.net will also show up.
We can avoid the asp.net related pages by telling google not to return pages containing the word asp.
For that ,frame the query and put -asp at the end.It will block everything related to asp.
Happy googling.

Turn off laptop monitor manually


Most of the laptops do not have an option to turn off the LCD display screen manually.Mostly the screen automatically switches off after a certain time interval.
Its better to conserve power by switching off manually.
Here is a simple application for that.

The application makes use of the c++ commands to access the display device and puts it into sleep mode,ie,turns off the display.Display can be brought back by simply pressing any key or by using the touchpad/mouse.

Using mChek with Airtel prepaid and postpaid




Airtel offers mchek service which can be used to pay mobile phone bills for postpaid customers and to make recharges for prepaid customers.
The service can be accessed through interactive voice response system by dialing 543219.
mChek asks for a credit card number and a pin number while signing up.The pin number serves as the authentication code for accessing and using the mChek facility.
Recharges can be done for a mimimum of 50rs, the amount credited will be the usual for prepaid subscribers. The best part is that mChek not only works for the regsitering number,it can also be used to recharge/pay bills for any airtel numbers,be it prepaid mobile or postpaid mobile or landline.

Special note: In case an user is registered with mChek,but not having outgoing facility due to low balance or unpaid postpaid bill, mChek cannot be accessed directly since 543219 cannot be dialled.There is a solution to access mChek even in such situations, goto airtel.in and go into "Easy Pay".In that page,select bill processing through mChek and give the amount and number.mChek will automatically ask for your pin number in your mobile through interactive reply mechanism.Just enter the pin and the bill will be paid.

Best ebook reader for ipod touch


After testing several pdf readers with ipod touch, the best pdf reader is found to be "good reader" by goodiware.
Goodreader has several innovative features for ebook viewing.It supports zooming and panning, and panning can be locked within up-down directions alone.There are also two modes for reading documents,one for low light and one for bright light conditions. It can also be rotated.Rotate is not controlled by the accelerometer,its a necessary feature because accidental turning may cause the document to turn.
The features of this product is endless.

The greatest feature is that it has a simple desktop application (GoodReaderUSB.exe) that can be used to drag/drop files directly to the ipod touch.

External USB hard disk not detected

Many external hard disks fail to get detected on some systems, whether they run Windows xp, windows vista or even linux.
The reason for this problem is the USB ports. Many USB ports are not directly connected to the motherboard, they use some internal hubs to connect to the cabinet of the PC.
The solution to this problem is to connect the external hard disk to a different USB port,preferably USB ports in the back of the CPU.
The drives fail to detect because they are not getting enough power from certain USB ports, connecting the external hard disk to the rear end of the CPU will solve the problem.
The fix mentioned was tested several times, and it works with all external hard disks.

OpenID: Login anywhere with a single id


OpenID Basics
Most websites require a user to login before they can start using their website. So,users are forced to signup at every single website they intend to use.The signup process is usually a time consuming process since email verification is mostly necessary in order to verify the validity of the user.
Yahoo's id can be used across its network (email,groups,answers etc),and Google's id can be used on its network (gmail,gtalk,blogger etc) and Microsoft has Passport (mail,Spaces,and all MS services including Windows itself).
But what about the other majority of internet not owned by Y!,Google or MS? Its where OpenID comes to the rescue.
Started in 2005, OpenID eliminates the need for multiple usernames across different websites.Its designed by the OpenId foundation which provides it as a open source implementation. OpenID can be signed up using one of the OpenID providers. Once signed up,it can be used across the network of websites that support OpenID.OpenID foundation claims that OpenID is supported by more than 50,000 websites.
Some major websites include blogger,wordpress,livejournal,scribd,digg,dailymotion,facebook etc.,and more and more websites are starting to support OpenID gradually.

Advantages
OpenID offers users ease of use and there is no need to sign up in websites supporting OpenID.
For website owners,the advantage is that more users will be signed up for their website since users dont need to signup separately, and users only need to sign in into OpenID and join the website.
So,users can easily join an OpenId supporting website.Thats a plus for both users as well as website owners.
Moreover, OpenID can be easily implemented by website owners.
And regarding security,the OpenId password will not be submitted to the website, it will be submitted only to the OpenID provider who acts as the middleman in the sign-in process.

Yahoo supports OpenID
Yahoo started to support OpenID in 2008 as a OpenID provider.The implication is that existing Y! ids can be used as OpenID logins (username/password).However, it needs to be enabled separately.
Just go to openid.yahoo.com and login with Y! username/password and enable OpenID.
After that, Y! id can be used to login into any OpenId website.
An important thing to be noted is that the Y! username/password should not be entered directly into any website's login boxes.Enter yahoo.com in the OpenID field.The browser will redirect to Y! authentication servers.Y! username/password should only be entered in Yahoo's login page.
Of course,the user has the option to sign up with any OpenID provider.
Even Google and Microsoft are OpenID providers.

Note:
OpenID providers: websites that allow to create OpenIDs (trivially, Y!,G and MS allow creation,but they can't be used for login in their own networks,but usable on all websites implemeting OpenID)
OpenID websites: websites that allow OpenID to be used as a login method (websites that allow users to login)

Yahoo groups ad container is obscuring mail content

Ever since Yahoo groups adopted the box type advertisements on top of email, users are irritated by the advertisements that hover over the email content rather than flowing with the content.
Yahoo groups adds these advertisements to all emails processed by the groups' system.
So, the email that comes via yahoo groups end up obscured,that is,partly hidden behind yahoo's own advertisements.
Every service need advertisement revenue,but ads should not be over the content.
Ads should not mask the content.The

elements are having absolute positioning values and they hover over the content.
This is predatory advertising.


Notice the green arrow,it points the advertisement.
This screenshot taken at 1600x900 resolution with latest Firefox.


This screenshot taken at 1024x768 with latest IE 8


This screenshot taken at 1024x768 with latest Firefox.


In all the screenshots, the ad masks the content of the email.
It masks images as well as text.
Atleast, this box should have a close or hide button.
Else,it should be positioned relative to the content.

I have contacted Y! groups, lets see if they correct this.
Y! ads spoilt the first ever earth rise photo by placing their ad over the image in my mail,
:-(

Update:
Y! has responded to my complaint, here is the response from yahoo.

RapidShare Fined $33 million



Court rules site, and others like it, are responsible for ensuring copyrighted material isn’t illegally hosted on their servers.

The Hamburg Regional Court of Germany has ruled against German-owned file hosting website RapidShare this past Tuesday. It found the site guilty of violation of German copyright law and set damages at about €24 million ($33.4 million).

In what could prove a key precedent, the court found Rapidshare, and by extension similar file-sharing sites, bear principle responsibility for ensuring copyright-protected material is not illegally posted on their servers.

The ruling was a major victory for German royalty collection agency GEMA, which had brought the suit against Rapidshare for allowing some 5,000 protected music titles to be posted on their site.

“The judgment states that the hosting service itself is now responsible for making sure that none of the music tracks concerned are distributed via its platform in the future,” said GEMA in a press release. “This means that the copyright holder is no longer required to perform the ongoing and complex checks.”

RapidShare’s been under assault by copyright holders for a while now, it’s most recent attacker being German book publishers who wanted the site placed on the ISP’s blacklist of blocked sites.

Apple's ipod 3.0 firmware unlocks bluetooth for 9.95USD

Apple released the iphone/ipod firmware 3.0 version recently.
The catch for ipod touch users is that this firmware upgrade is that it activates(unlocks) the bluetooth chip in ipod touch.Ever since it was released,there was no bluetooth option in ipod touch,but it had an option to connect with Nike gadgets.
The chip that was used for Nike is now being unlocked to provide bluetooth access to ipod touch,enabling multiplayer games,wireless headphones etc.
But, there is a catch here too, the firmware upgrade is not available for free.
It needs to be purchased for 9.95$ (USD). (file size 257.8MB)
Normally, it is the duty of the vendor to provide firmware updates for free.
Imagine Nokia selling its phone's firmware updates,or Microsoft selling service packs!
Apple has monopoly in this segment since they are the leaders.

And then, there is this problem of Apple bundling stuff.
Quick time is bundled with itunes.Why cant Apple integrate quicktimes' codecs into itunes itself?
I have itunes 8.1 and its been bugging me to upgrade to itunes 8.2,but i declined the upgrade. So, what Apple did was to bundle the ipod touch 3.0 firmware with itunes 8.2!I need to upgrade to itunes 8.2 in order to upgrade to 3.0 firmware which i bought for 10USD.

All in all, the bluetooth unlocking is too good to resist.
The upgrades in 3.0 include,

Stereo Bluetooth



Multiplayer peer-2-peer gaming



Landscape mode typing in Safari,Notes etc

Mobile number portability by September 2009


- MNP (Mobile Number Portability) will allow a mobile customer to change his/her service provider for any reason, while keeping the old number intact, all for a small fee.

- IT minister A.Raja had said that MNP will begin in October. (on June 2009)

- Mobile number portability (MNP) is set to roll out in Chennai from September, the focus will now shift from pricing to quality of service.

- In most of the countries where MNP is prevalent, the subscribers are not charged for availing the service.

- TRAI had earlier recommended a charge of Rs.200 for the number changing procedure,since higher prices may make the service unattractive.

- Number portability will be able to keep a check on the quality of service offered by mobile service companies and is also likely to provide a level playing field for all mobile companies, including new entrants.
