Stocks closed in the red for the third consecutive week, largely triggered by US's worst unemployment numbers in 26 years and dismal housing data. There were also apprehensions that the Reserve Bank of India (RBI) may leave the indicative rates unchanged or tinker just a little with them in the upcoming third quarter review.

The downward rally was led by mainly by IT and banking majors. ICICI Bank, HDFC Bank, State Bank of India, Infosys and TCS fell by over 2 per cent.

The Bombay Stock Exchange Sensitive Index or Sensex fell by 139.49 points to close at 8,674.35 points. The Nifty closed at 2678.55, down 35.25 points.

Yesterday, US indices fell quite sharply on bad unemployment data and reports that Microsoft plans to cut 5,000 jobs. The Dow Jones and S & P 500 were down by 1.28 per cent and 1.52 per cent, respectively.

The market breadth was negative. Out of 2,503 stocks traded, 796 advanced and 1,609 declined.

Deven Choksey, managing director, K R Choksey said that though the initial corporate results were satisfactory, investors are still cautious about committing themselves.

While oil & gas, healthcare and consumer durables indices were up less than one per cent, others fell. Bankex fell 4.16 per cent, metal index fell 3.35 per cent, capital goods (-2.87 per cent), realty (-2.45 per cent) and IT (-2.2 per cent).

The 14-year-old left her home in Idaho Springs, Colorado, about 10 a.m. August 16, 1983. When she wasn't back that afternoon, her family called police.

Miller normally jogged in a nearby park. Investigators say she may have been seen last talking with a man who was behind the wheel of a red pickup with a white camper top and out-of-state license plates.

Immediately after Miller's disappearance, many red pickups were stopped, but none could be linked to Miller's disappearance.

Miller was not carrying any cash or personal belongings. Family and friends say she always left a note for her parents if she planned to be gone long.

But on the day she vanished, Miller left no note, her family told police. She didn't take the money she earned babysitting. Her parents insisted she would not have left intentionally for such a long time.

Over the years, the Beth Miller case has taken many twists and turns. Most recently, a grand jury investigation was called in 2007, but no indictments were returned.

Several theories are still being investigated, but over the years, no clues have surfaced. No remains have been found that could be identified as Miller's.

Police had suspicions that an Ohio man may have been involved in Miller's abduction, but he was never charged.

A serial killer from Mississippi claimed he had killed Beth Miller, but police dismissed the lead because his story didn't add up.

The most credible lead focused on a New Mexico man named Edward Apodaca, who is now dead. His former girlfriend claimed that she had helped him bury Miller in the mountains near Idaho Springs, but when police searched with cadaver dogs and excavated the area, no remains were found.

Several sightings of women thought to be Beth Miller have been reported. In 1995, a woman who was picked up by police in Tampa, Florida, claimed she was Beth Miller. Miller's family flew down to meet the woman, only to find that she was not their daughter. :(
In a bid to widen its geographical coverage, Norton, the consumer arm of Symantec, plans to appoint a large network of sub-distributors across the country.

"To meet our objective of wider market coverage, we plan to appoint at least one sub-distributor in each of the state capitals of the country. We have recently appointed three new sub-distributors for Rajasthan, Punjab and Madhya Pradesh and one for the entire North-Eastern region. All these sub-distributors will promote the entire Norton product line-up to the home, SOHO and SMB segments through their networks of resellers, retailers, and assemblers," said Gaurav Kanwal, Country Sales Manager (Norton), Symantec India.

Norton's plan is to double its market coverage to 360 cities and towns from the existing 180 and thus also double its registered reseller base from 1,800 to 3,600.

Another area, where Symantec plans to increase  >:( its footprint is the retail segment. "We are extremely bullish about retail and are looking at expanding our retail presence across India. Currently, we have tie-ups with major retail chains like Croma, Staples and Reliance Digital. We will now concentrate on selling our products through alternate channels too," Kanwal added.

While, the vendor already has Ingram Micro and Redington as its national distributors, it has appointed Aladdin Multimedia as its exclusive distributor for the retail segment. Aladdin Multimedia mainly deals with LFRs like Croma and Staples.

The vendor is also planning to add more layers to its Norton Champs partner program. It plans to add training and an online test. "We plan to start a newsletter for our partners. This newsletter will not only feature new products but would feature articles sent in by partners. They can write about topics like threat management, self-made businesses and their experiences while dealing with Symantec," informed Kanwal.

The version of Windows 7 Beta 1 that Microsoft made available for download on its Technet site Thursday does not support upgrades from systems running its Windows XP operating system, according to a first look at the available code in the CRN Test Center.

It does, however, permit upgrades from Vista SP1 to Windows 7.

A Microsoft spokesman said that no final decisions have yet been made about what will be included or not included in the generally available version of Windows 7, but that the company as a practice advises only clean installations of operating systems during the beta phase anyway.

For now, the beta version of Windows 7 only permits upgrades from Vista SP1 -- meaning there is at the moment no way to test or evaluate a straight XP-to-Windows 7 migration.

"We've just been telling people like we always do, conduct a clean install. That's the safest bet anyway," the spokesman said. "It shouldn't be too much of a surprise."

Microsoft announced late Wednesday night in Las Vegas that it was making its first beta version of its next generation desktop OS available via Technet and MSDN, and CEO Steve Ballmer said the general public would have access to the beta -- for free-- as of Friday. The beta will work through August of this year, giving virtually the entire market an opportunity to play around with it and evaluate Windows 7 before they have to pay for it.

The Test Center's first look at Windows 7 in beta form found:

-- Attempts to upgrade from XP were met by a warning that: "To upgrade to Windows 7, the computer needs to be running Vista with Service Pack 1 (SP1) or later. Upgrading from Windows XP to any edition of Windows 7 is not supported;"

-- On the same PC test bed, performance measured by Primate Labs' Geekbench 2.1 benchmarking software indicates that performance deteriorates slightly on the same PC from Windows XP to Windows Vista Ultimate to Windows 7 Ultimate;

-- Once Vista SP1 is installed and running, the upgrade from Vista Ultimate to Windows 7 Ultimate took an hour and 16 minutes. It is an extremely smooth upgrade -- something that could be a relief to a channel and a market that suffered extreme headaches in trying to go from XP to Vista. Compared to complaints from the market during previous OS upgrades, Vista-to-Windows 7 is a breeze, introduces subtle-but-nice interface changes and provides refreshingly strong support for several basic drivers and applications.

Our test bed was built with an AMD Phenom 9550 Quad-Core processor at 2.20GHz, 4 GB of RAM, an Nvidia 6100 nForce 4300 card. In our upgrade from Vista Ultimate to Windows 7 Ultimate, we included, among other applications, Firefox 3.0, Google Chrome and Safari browsers; Microsoft Office 2007; WordPerfect Office X4; Skype; the Digsby IM client; a FireFox plug-in, Ubiquity; and a new, free application made available this week, from Tech Smith, called "Jing," which provides for image and video desktop screen captures. Adobe Flash player was also on the Vista system.

Following the upgrade, every single application worked as it should. Skype in Windows 7 did come with a compatibility warning, but upon opening it up and trying it out, it worked just fine.

Microsoft did provide a warning to back up any .mp3 files before upgrading from Vista to Windows 7; however, the upgrade went through and the .mp3 files we had on the system survived just fine.

Once installed, Windows 7 found easy access to a shared drive on the Test Center network. Once the driver for the Oki Data printer in the lab was installed, printing from the Windows 7 PC over the network was happily uneventful.

A note of caution, though: If you try to upgrade a Vista PC and you haven't yet installed SP 1 and all essential updates from Microsoft, the process could take an additional two hours. It did for us, so keep that in mind if you're planning to try the Vista to Windows 7 Beta 1 upgrade.

More testing on Windows 7 will be needed to evaluate its security, network management and support for more applications and drivers. But at first blush, the upgrade that caused so many tempers to flare during the last OS release seems to have been alleviated greatly this time around.

It remains to be seen, however, how the market will respond if Microsoft continues to deny an upgrade from XP to Windows 7.
Intel will be cutting prices on select processors on January 18th. The price cut which ranges from 5 percent to 24 percent is not as aggressive as some of the price cut seen last year

While there are minor price cuts on many processors, and larger cuts on some of the slow moving ones, the focus will be on the newly positioned Intel Core2Duo E7400 and Pentium Dual Core 5200.

This quarter the fastest moving processor in the system builder market is expected to the Pentium DualCore 5200 which will be available at Rs 3,500.

In other news, Intel is also expected to debut three new Core 2 Quad processors with a 65W rating compared to around 95 W for most of the current processors. These processors are Q8200s, Q9400s, and Q9550s, and are not expected to be launched in Indian market immediately. These processors which are prefixed with 'S' will be priced at a premium of Rs 3,000 and Rs 5,000 over their 95W cousins.

== Explanation of table ==

* '''Algorithm''' = name of algorithm
* '''Reference for algorithm''' = where to find out more about given algorithm
* '''Reference for experiment''' = where to find out more about evaluation of given algorithm with TOEFL questions
* '''Type''' = general type of algorithm: corpus-based, lexicon-based, hybrid
* '''Correct''' = percent of 80 questions that given algorithm answered correctly
* '''95% confidence''' = confidence interval calculated using [ Binomial Exact Test]
* table rows sorted in order of increasing percent correct
* several WordNet-based similarity measures are implemented in [ Ted Pedersen]'s [ WordNet::Similarity] package
* LSA = Latent Semantic Analysis
* PMI-IR = Pointwise Mutual Information - Information Retrieval
* PR = Product Rule
* PPMIC = Positive Pointwise Mutual Information with Cosine
* GLSA = Generalized Latent Semantic Analysis
* CWO = Context Window Overlapping
* DS = Dependency Space

== Caveats ==

* the performance of a corpus-based algorithm depends on the corpus, so the difference in performance between two corpus-based systems may be due to the different corpora, rather than the different algorithms
* the TOEFL questions include nouns, verbs, and adjectives, but some of the WordNet-based algorithms were only designed to work with nouns
* some of the algorithms may have been tuned on the TOEFL questions

Interview FAQ's in Java / swing in java
Jan 24, 2009, 12:49 AM
Java Swing is a GUI toolkit for Java. Swing is one part of the Java Foundation Classes (JFC). Swing includes graphical user interface (GUI) widgets such as text boxes, buttons, split-panes, and tables.

Swing widgets provide more sophisticated GUI components than the earlier Abstract Window Toolkit. Since they are written in pure Java, they run the same on all platforms, unlike the AWT which is tied to the underlying platform's windowing system. Swing supports pluggable look and feel – not by using the native platform's facilities, but by roughly emulating them. This means you can get any supported look and feel on any platform. The disadvantage of lightweight components is possibly slower execution. The advantage is uniform behavior on all platforms.


The Internet Foundation Classes (IFC) were a graphics library for Java originally developed by Netscape Communications Corporation and first released on Dec 16, 1996.

On April 2, 1996, Sun Microsystems and Netscape Communications Corporation announced their intention to combine IFC with other technologies to form the Java Foundation Classes. In addition to the components originally provided by IFC, Swing introduced a mechanism that allowed the look and feel of every component in an application to be altered without making substantial changes to the application code. The introduction of support for a pluggable look and feel allowed Swing components to emulate the appearance of native components while still retaining the benefits of platform independence. This feature also makes it easy to have an individual application's appearance look very different from other native programs.

Originally distributed as a separately downloadable library, Swing has been included as part of the Java Standard Edition since release 1.2. The Swing classes are contained in the javax.swing package hierarchy.


The following is a Hello World program using Swing.

import javax.swing.JFrame;
import javax.swing.JLabel;

public final class HelloWorld extends JFrame {
private HelloWorld() {
getContentPane().add(new JLabel("Hello, World!"));

public static void main(String[] args) {
new HelloWorld().setVisible(true);
