Oracle to unveil new 11g database system

Oracle is preparing a major product launch of its new 11g database
system for this year's GITEX Technology Week, under-lining the
strategic significance of the show.

The vendor's partner community will also be as present as ever, with
more than 40 partners sharing Oracle's vast GITEX Business Solutions
stand. This will allow the firm to demonstrate its range of
industry-specific solutions, as well as specialist integration and
development partners.

Oracle's core strengths will be clearly demonstrated with the
high-profile 11g launch, which will allow regional enterprise decision
makers their first public look at the new database system. Prior to
the show, selected enterprises across the Middle East will also be
involved in beta testing 11g.

"Managing the risk and cost of implementing new software,
applications, and other system changes and updates is one of the most
significant challenges facing organisations in the Middle East," says
Dana Murugan, senior marketing director for Oracle in the Middle East
and Africa.

"Oracle Database 11g is ideally suited to enable those changes with
the industry's highest degree of automation and system availability,
and we believe that GITEX Technology Week provides an unparalleled
opportunity for both existing Oracle customers and new ones to get a
look at the capabilities of Oracle 11g," Murugan adds.
The major vendor's latest acquisitions will also be under the
spotlight as Oracle discusses its recent purchase of business
intelligence and business performance management (BPM) firm Hyperion,
and how this will expand Oracle's enterprise offerings.

Show visitors will also learn more about the latest trends in customer
relationship management (CRM) solutions as part of Oracle's
acquisition of Siebel, and get a closer look at the Oracle E-Business


Browsing web sites despite Blocked Access at your Office, School or University

Access blocked web sites at your Office, School or University
Is your Internet access restricted? Is your School, University ,Office
or Government not allowing you to access famous web sites like Orkut,
Hi5, Blogger, MySpace and other sites? Here are few tricks which you
can play to access your favourite web sites by bypassing the ban

Trick 1. Anonymous Browsing

Use free Proxy Server which allows you to browse the web anonymously
and access sites that are blocked. Here is the list of few proxy
servers which I came across while Googling..

http://www.proxybrowsing.com/
http://www.hidemyass.com/
http://www.browserjump.com/
http://www.ninjaproxy.com/
http://www.kproxy.com/
http://proxify.com/
http://www.w3privacy.com/

Trick 2. Google Translation

In case if your organization has blocked all the anonymous proxy
servers, you can use Google Translator( also called as Google Language
Tools) service as your proxy server. Google Translator translate pages
from one language to another language. You can surf the blocked web
pages by translating them from English to English(or any language
which you desire).

Replace WEBSITE with your favourite site address in the following URL
and start accessing them

http://www.google.com/translate?langpair=en| en&u=WEBSITE

Example: http://www.google.com/translate?langpair=en| en&u=http://itgroup-india.blogspot.com

Trick 3. Google Mobile Search

Google Mobile search service translates HTML pages to mobile phone
browser compatible by removing style sheets and java script. You can
use this service to browse the web pages in text only format.

Replace WEBSITE with your favorite site address in the following URL
to start accessing them

http://www.google.com/gwt/n?u=WEBSITE

Example: http://www.google.com/gwt/n?u=itgroup-india.blogspot.com

Trick 4. Search Engine Cache

Enter the blocked URL in Google or Yahoo search engines and then visit
the cached copy of the page.



Windows Live SkyDrive Logo

Besides offering extra space to Windows Live Hotmail Live users,
Microsoft has also rolled out an online storage service called Windows
Live SkyDrive. This new centralized Web site allows consumers to access
all of Windows Live services from just one place.

Basically, Windows Live SkyDrive provides users with access to their
files, information from the Internet as well as options to share it with
others anywhere and anytime.

According to Jaspreet Bindra, India Country Manager, Online Services,
Microsoft India, "This is the first time Microsoft has offered sharing
and storage in this manner and we're excited to roll it out to our
customers. We are hoping that this platform would prove to be an exciting
way of offering customers a range of services to meet their storage and
file-sharing needs with maximum security."

There are three separate areas for peoples' information on Windows Live
SkyDrive: Personal, Shared and Public. The information stored in the
Personal and Shared areas are secured with the user's username and
password, while the Public area is open to everybody on the Internet.

As of now, Windows Live SkyDrive is yet in the beta stage, and currently
offers 500MB of free storage, allowing users to store approximately 100
songs, 1,000 Office documents, or 3,000 digital photos at 1200×1200 pixel
resolutions.

Here are some of the salient features of Windows Live SkyDrive:

  * Enhanced user interface

  * Drag and drop file upload capability allowing simple upload of single
    files or multiple files at once

  * Thumbnail images in the folder views

  * An area showing other customers' SkyDrive folders recently visited

  * Simple file embedding from SkyDrive to other places on the Web (such
    as your Blog)

  * Active X uploading to quickly add multiple files at once

    Microsoft also said that it would further enhance its Windows Live
    SkyDrive service by paying heed to customer feed and carrying out
    constant research.

    Currently, the initial beta of Windows Live SkyDrive is available
    only in the US, UK and India.

You can access Windows Live SkyDrive

How do large Web sites handle the load of millions of visitors a day?

One of the surprising things about Web sites is that, in certain cases, a
very small machine can handle a huge number of visitors. For example,
imagine that you have a simple Web site containing a number of static
pages (in this case, "static" means that everybody sees the same version
of any page when they view it). If you took a normal 500MHz Celeron
machine running Windows NT or Linux, loaded the Apache Web server on it,
and connected this machine to the Internet with a T3 line (45 million
bits per second), you could handle hundreds of thousands of visitors per
day. Many ISPs will rent you a dedicated-machine configuration like this
for $1,000 or less per month. This configuration will work great unless:

  * You need to handle millions of visitors per day.

  * The single machine fails (in this case, your site will be down until
    a new machine is installed and configured).

  * The pages are extremely large or complicated.

  * The pages need to change dynamically on a per-user basis.

  * Any back-end processing needs to be performed to create the contents
    of the page or to process a request on the page.

Since most of the large Web sites meet all of these conditions, they need
significantly larger infrastructures.

There are three main strategies for handling the load:

  1. The site can invest in a single huge machine with lots of processing
    power, memory, disk space and redundancy.

  2. The site can distribute the load across a number of machines.

  3. The site can use some combination of the first two options.

When you visit a site that has a different URL every time you visit (for
example www1.xyz.com, www2.xyz.com, www3.xyz.com, etc.), then you know
that the site is using the second approach at the front end. Typically
the site will have an array of stand-alone machines that are each running
Web server software. They all have access to an identical copy of the
pages for the site. The incoming requests for pages are spread across all
of the machines in one of two ways:

  * The Domain Name Server (DNS) for the site can distribute the load.
    DNS is an Internet service that translates domain names into IP
    addresses. Each time a request is made for the Web server, DNS
    rotates through the available IP addresses in a circular way to share
    the load. The individual servers would have common access to the same
    set of Web pages for the site.

  * Load balancing switches can distribute the load. All requests for the
    Web site arrive at a machine that then passes the request to one of
    the available servers. The switch can find out from the servers which
    one is least loaded, so all of them are doing an equal amount of
    work. This is the approach that HowStuffWorks uses with its servers.
    The load balancer spreads the load among three different Web servers.
    One of the three can fail with no effect on the site.

The advantage of this redundant approach is that the failure of any one
machine does not cause a problem -- the other machines pick up the load.
It is also easy to add capacity in an incremental way. The disadvantage
is that these machines will still have to talk to some sort of
centralized database if there is any transaction processing going on.

Microsoft's TerraServer takes the "single large machine" approach.
Terraserver stores several terabytes of satellite imagery data and
handles millions of requests for this information. The site uses huge
enterprise-class machines to handle the load. For example, a single
Digital AlphaServer 8400 used at TerraServer has eight 440 MHz 64-bit
processors and 10 GB of error checked and corrected RAM. See the
technology description for some truly impressive specifications!


How do viruses and worms spread in e-mail?

There are all sorts of things you can find in your e-mail box. In the
"destructive" and/or "annoying" category go e-mail attachments that
contain:

  * Trojan horses

  * Worms

  * Viruses

In many cases, e-mail viruses are not "true" viruses because they cannot
replicate without human interaction. Nonetheless, they have been very
effective at shutting down major e-mail systems. See How Computer Viruses
Work for details on viruses.

A Trojan horse, aptly named after the seemingly harmless tool of
destruction in Homer's Iliad, secretly carries often-damaging software in
a "plain wrapper." The plain wrapper is normally an e-mail file
attachment from someone you may or may not know. The file attachment name
itself can also be very misleading. When you run the attachment, it can
do all sorts of things, from erasing files to changing your desktop. It
then sends itself along to other people in your address book so that it
can propagate itself.

Here are two examples to help you understand how e-mail viruses work.
According to this page from Symantec:

  Worm.ExploreZip is a worm that contains a malicious payload. The worm
  utilizes Microsoft Outlook, Outlook Express, Exchange to mail itself
  out by replying to unread messages in your Inbox. The worm will also
  search the mapped drives and networked machines for Windows
  installations and copy itself to the Windows directory of the remote
  machine and modify the WIN.INI accordingly.

  The payload of the worm will destroy any file with the extension .h,
  .c, .cpp, asm, .doc, .ppt, or .xls on your hard drives, any mapped
  drives, and any network machines that are accessible each time it is
  executed. This continues to occur until the worm is removed.

  You may receive the worm as an attachment called zipped_files.exe,
  masquerading itself as the usual self-extracting zip file. But, when
  run, this executable will copy itself to your Windows System directory
  with the filename Explore.exe or to your Windows directory with the
  filename _setup.exe. The worm modifies your WIN.INI or registry such
  that the file Explore.exe is executed each time you start Windows.

See also this page for details.

Symantec offers more technical information and explains what you need to
do if you suspect Worm.ExploreZip is in your system.

In certain special cases, e-mail attachments can execute even without
your interaction. According to this Symantec Web page:

  VBS.BubbleBoy is a worm that works under Windows 98 and Windows 2000.
  The worm will also work under Windows 95 only if the Windows Scripting
  Host is installed. The worm will only work with the English and Spanish
  versions of the operating systems, and not with Windows NT.

  Microsoft Outlook (or Express) with Internet Explorer 5 must be used in
  order for the worm to propagate.

  The worm utilizes a known security hole in Microsoft Outlook/IE5 to
  insert a script file, UPDATE.HTA , when the e-mail is viewed. It is not
  necessary to detach and run an attachment.

  UPDATE.HTA is placed in Program-StartUp of the Start menu. Therefore,
  the infection routine is not executed until the next time you start
  your computer. UPDATE.HTA is a script file that uses MS Outlook to send
  the worm e-mail message to everyone in the MS Outlook address book. By
  patching the known security hole in Microsoft Outlook/IE5, the worm
  will no longer propagate.

Microsoft has more information on this worm.

Keep your virus software up-to-date with the latest virus signatures from
the software vendor, since the anti-virus software cannot detect new
viruses without an update. If you use Norton AntiVirus software, ensure
that Auto-Protect is enabled. Current Norton AntiVirus software
automatically alerts you when your virus signature files are over 30 days
old. Norton's LiveUpdate can also automate updating.

If you think a virus has infected your PC thanks to an e-mail virus that
mails itself to people in your address book, call those people and tell
them not to open the messages or attachments -- that is the only
effective way to stop the spread.

A banana a day keeps the doctor away !!

Bananas contain three natural sugars - sucrose, fructose and glucose
combined with fiber. A banana gives an instant, sustained and substantial
boost of energy.

Research has proven that just two bananas provide enough energy for a
strenuous 90-minute workout. No wonder the banana is the number one fruit
with the world's leading athletes.

But energy isn't the only way a banana can help us keep fit. It can also
help overcome or prevent a substantial number of illnesses and conditions,
making it a must to add to our daily diet.

Depression: According to a recent survey undertaken by MIND amongst people
suffering from depression, many felt much better after eating a banana.

This

is because bananas contain tryptophan, a type of protein that the body
converts into serotonin, known to make you relax, improve your mood and
generally make you feel happier.

PMS: Forget the pills - eat a banana. The vitamin B6 it contains regulates
blood glucose levels, which can affect your mood.

Anemia: High in iron, bananas can stimulate the production of hemoglobin in
the blood and so helps in cases of anemia.

Blood Pressure: This unique tropical fruit is extremely high in potassium
yet low in salt, making it perfect to beat blood pressure. So much so, the
US Food and Drug Administration has just allowed the banana industry to make
official claims for the fruit's ability to reduce the risk of blood pressure
and stroke.

Brain Power: 200 students at a Twickenham (Middlesex) school ( England) were
helped through their exams this year by eating bananas at breakfast, break,
and lunch in a bid to boost their brain power. Research has shown that the
potassium-packed fruit can assist learning by making pupils more alert.

Constipation: High in fiber, including bananas in the diet can help restore
normal bowel action, helping to overcome the problem without resorting to
laxatives.

Hangovers: One of the quickest ways of curing a hangover is to make a banana
milkshake, sweetened with honey. The banana calms the stomach and, with the
help of the honey, builds up depleted blood sugar levels, while the milk
soothes and re-hydrates your system.

Heartburn: Bananas have a natural antacid effect in the body, so if you
suffer from heartburn, try eating a banana for soothing relief.

Morning Sickness: Snacking on bananas between meals helps to keep blood
sugar levels up and avoid morning sickness.

Mosquito bites: Before reaching for the insect bite cream, try rubbing the
affected area with the inside of a banana skin. Many people find it
amazingly successful at reducing swelling and irritation.

Nerves: Bananas are high in B vitamins that help calm the nervous system.

Overweight and at work? Studies at the Institute of Psychology in Austria
found pressure at work leads to gorging on comfort food like chocolate and
chips. Looking at 5,000 hospital patients, researchers found the most obese
were more likely to be in high-pressure jobs. The report concluded that, to
avoid panic-induced food cravings, we need to control our blood sugar levels
by snacking on high carbohydrate foods every two hours to keep levels
steady.

Ulcers: The banana is used as the dietary food against intestinal disorders
because of its soft texture and smoothness. It is the only raw fruit that
can be eaten without distress in over-chronicler cases. It also neutralizes
over-acidity and reduces irritation by coating the lining of the stomach.

Temperature control: Many other cultures see bananas as a "cooling"

fruit

that can lower both the physical and emotional temperature of expectant
mothers. In Thailand , for example, pregnant women eat bananas to ensure
their baby is born with a cool temperature.

Seasonal Affective Disorder (SAD): Bananas can help SAD sufferers because
they contain the natural mood enhancer tryptophan.

Smoking &Tobacco Use: Bananas can also help people trying to give up
smoking. The B6, B12 they contain, as well as the potassium and magnesium
found in them, help the body recover from the effects of nicotine
withdrawal..

Stress: Potassium is a vital mineral, which helps normalize the heartbeat,
sends oxygen to the brain and regulates your body's water balance. When we
are stressed, our metabolic rate rises, thereby reducing our potassium
levels. These can be rebalanced with the help of a high-potassium banana
snack.

Strokes: According to research in The New England Journal of Medicine,
eating bananas as part of a regular diet can cut the risk of death by
strokes by as much as 40%!

Warts: Those keen on natural alternatives swear that if you want to kill off
a wart, take a piece of banana skin and place it on the wart, with the
yellow side out. Carefully hold the skin in place with a plaster or surgical
tape!

So, a banana really is a natural remedy for many ills. When you compare it
to an apple, it has four times the protein, twice the carbohydrate, three
times the phosphorus, five times the vitamin A and iron, and twice the other
vitamins and minerals. It is also rich in potassium and is one of the best
value foods around So maybe its time to change that well-known phrase so
that we say, "A banana a day keeps the doctor away!"

Debug ASP.Net web app in IE/Firefox browser(s) with VS 2005

I found one problem today like i have IE7 installed on my machine, but when i debug ASP.net site in Visual Studio 2005 , it opens Firefox browser. I wanted to change that behavior, and wanted to wants to launch IE as the browser when I debug my web site.


after searching net for sometime, i got a way to tackle this, here it goes.

To fix the issue

-> Right click on any .ASPX page in the Solution Explorer, and select "Browse with...."

-> A dialog pops up. If you Select IE and click "Make Default", VS should now use IE as it's browser.

or If you Select Firefox and click "Make Default", VS should now use Firefox as it's browser.

Tafiti - Search tool to help Web research -based on Silverlight

Microsoft recently announced the availability of Tafiti, a Silverlight-based search tool on top of Microsoft's Live Search engine. Tafiti, which means "do research" in Swahili, is an experimental search front-end from Microsoft, designed to help people use the Web for research projects that span multiple search queries and sessions by helping visualize, store, and share research results. Tafiti uses both Microsoft Silverlight and Live Search to explore the intersection of richer experiences on the Web and the increasing specialization of search.


It enhances searching on the web by allowing users to store and share search results across multiple queries and sessions. This is accomplished by using "shelfs" to store one or more search results simply by dragging the search result onto one of five shelf spaces. Shelfs can then be stored for future use, or can be emailed or blogged about with ease.

Tafiti includes a carousel to simplify the organization of returned search results. By rotating the carousel, one can access search results from the web, images, news, RSS feeds, or books. Tafiti also supports a Tree View where by search results are placed on the limbs of a tree which can be rotated and zoomed as necessary to visualize the search result.

visit http://www.tafiti.com/ to feel the real joy of re-Searching the WEB, out o the box experience,

what people are saying (at channel9.msdn.com) ?
  • Whenever I do a search (Google, MSN, etc), I quickly scan through the results and middle-click on any result link that looks interesting. This opens a new tab for each one I click on, without changing focus to the new tabs. This way I pick all the relevant-looking links while still in the same frame of mind and know I will eventually get to them, and not be distracted by any one link and then forget about checking the remaining interesting links.

    Gripe? I can't find any way to open the results from Tafiti in a new tab. It insists that you left-click on the results and therefore force a completely new browser window to pop up - how annoying!

    This is part of my gripe with SilverLight - it seems they succumbed to the lowest common denominator and only give you "a mouse button" as opposed to left/right/middle/ buttons (and scroll wheel). This is 2007 - we have moved well past 1 button mice a long time ago.

    I hope this is just developers creating SilverLight apps that don't implement support for additional mouse button functionality rather than SilverLight only supporting one button from the start.

  • nice silver light app - I wish I could get my silver light dev environment working ...

  • Interesting, any way. Doesn't seem useful at all, but it is pleasing to the eye. The ability to drag links and searches to the glass pane is interesting.

The namespace already contains a definition for... - ASP.NET Error

Recently while working on a web project, I added a file in my web solution and started getting this error:

"The namespace <global namespace > already contains a definition for namespace.xxx"

I wondered that I may have added a class that was already in the solution and need to edit the name of it ?!!

So I Use the Find and Replace tool to search for all classes with the same name and i got one there! to continue working i renamed new class name ...
