How to know when a stock is really a bargain
When the market plunges 5% in one day, lots of stocks might look like they're on sale. But are they? Here's how to ID the true values. (Get the data below at morningstar.com.)
- Step 1 Look at a stock's forward P/E. This is the price investors are willing to pay for every dollar of expected earnings. Compare this ratio with that of the company's peers and industry benchmark. The S&P 500's forward P/E is 13.8. What you want to see: ratio lower than average but not too low (Matthew Sauer, a senior vice president at value-oriented Ariel Investments, is cautious about P/Es below 8).
- Step 2 Look at the trailing P/E, which is based on a company's past earnings. It will show whether a stock was cheap before the market's recent free-fall. What you want to see: ratio lower than industry average.
- Step 3 Check the price-to-cash-flow ratio. This shows how much cash a company generates per share. It's sometimes a more reliable measure of value than P/E because cash, unlike earnings, cannot be manipulated easily by accountants. Again, compare the ratio with the industry benchmark and peers. What you want to see: ratio lower than average.
- Step 4 Look for stability. A company that isn't highly leveraged (laden with debt) has a better chance of riding out the economic downturn. To find out if that's the case, see the company's balance sheet at The SEC's Web site. Divide total assets by total equity. What you want to see: ratio of 2 or lower (10 or lower for financial firms).
- Step 5 Read the news. No matter what the numbers say, a stock could be a rotten choice if, say, the company is embroiled in a potentially costly lawsuit. Not every stock that appears cheap is a good deal. What you want to see: no obvious problems. Bottom Line: If a stock passes all these tests, you could be onto a good buy.

(Unevaluated) Cost of UI performance
Scenario – Accounting application, data entry operators works 20-30 $/hour, total 10 data entry operators
What is the average time user wastes on UI per day? (For example – waiting for data, scrolling up-down/right-left, performance of controls (loading etc))
- 10-12 minutes per day of 8 hrs
Average time wasted per week per user –5 days * 12 minutes = 60 minutes
Average time wasted per month – 4 weeks * 60 minutes = 4 hours
Average time wasted per year – 12 months * 4 hours = 48-50 hours
Average time wasted for 10 data entry operators – 10 persons * 50 hours = 500 hours
Total cost = $20 or $30 * 500 hours = $10K to $15K
Conclusion – while designing UI, only look-n-feel is not important but you also need to consider for whom you are solving & how fast.

Microsoft WorldWide Telescope
The WorldWide Telescope (WWT) is a Web 2.0 visualization software environment that enables your computer to function as a virtual telescope.
The WorldWide Telescope is created with the Microsoft high performance Visual Experience Engine and allows seamless panning and zooming around the night sky, planets, and image environments.
The massive amounts of data generated by the various scientific and research facilities is currently hundreds of terabytes and will soon be measured in petabytes. Yet sharing this information is problematic for several reasons. By enabling comparison of data from diverse sources--space and ground, and radio, optical, infrared, and other wavelengths--WWT provides a single Internet-based portal to this unprecedented catalog of data to study the evolving universe. By connecting to the same source materials that scientists at NASA and Caltech are using for their research, WWT is a powerful “virtual observatory” for scientists, educators, and the public. Researching the sky as easy as viewing a Web site and is accessible to everyone with an Internet connection.
WWT also contains features to help you explore the Earth, satellites, such as the Moon, and 360 degree panoramas of Yosemite’s Half Dome and other locations.

Arithmetic overflow caused death of several people!
The Therac-25 was a computer controlled radiation therapy machine produced by Atomic Energy Canada Ltd. in the 1980s. The machine offered two modes of therapy, including "Megavolt X-ray therapy". The problem happened when the machine's software failed to move a component into place to convert an electron beam into X-rays, allowing a high power electron beam to directly strike patients. At least 5 patients died of radiation poisoning from dosages that were sometimes in the hundreds of Grays.
AECL did not have the machine's software independently reviewed. AECL did not assess what potential failure modes existed. The system documentation did not explain error codes. AECL ignored incident reports.
The problem turned out to be a software bug which intermittently caused an arithmetic overflow. When this happened, the software bypassed safety checks. So the machine killed people that were simply undergoing therapy.

Google’s APRIL-2007 Innovation
This year - APRIL - Google nerds introduced Google TiSP - a new FREE in-home wireless broadband service.
According to Google “TiSP is a fully functional, end-to-end system that provides in-home wireless access by connecting your commode-based TiSP wireless router to one of thousands of TiSP Access Nodes via fiber-optic cable strung through your local municipal sewage lines.”
Also check 'FOOL' list of some past 'APRIL' innovations from Google (Looks these people don't have much work than collecting money from ad work):
• Gmail Pape
• Google Romance introduced a new contextually-based dating service.
• Google Gulp, a line of "smart drinks" that make you surf the Web more efficiently.
• Engineering job opportunity at the lunar hosting and research center in outer space.
• Pigeon pecking could make Google's search algorithms better.
• The MentalPlex gag in 2000 had searchers communicate their intentions telepathically.
Thank You from Lenovo
Mistakes can happens from anyone.... here is thank you from Lenovo after their product registration.

Top 20 general medicines
I am not allopathic fan and avoids as much as possible. But (therefore) when time comes I don't get name of any medicine. Here is one great article (which disappeared therefore can't add link) which discusses top 20 medicines.... added here as an handy reference...
ALLERGIES, MULTISYMPTOM
1. Claritin
One dose helps halt hay fever and other sinus allergies for up to 24 hours, compared with 4 to 6 hours for other antihistamines. Claritin is also the first OTC antihistamine that's truly nonsedating, which means you can finally operate heavy machinery (or just drive your car). One caution: Claritin-D also contains a decongesting stimulant, so take it at least 4 hours before bedtime.
ALLERGIES, SKIN
2. Benadryl
Whether it's the burning of a bee sting or the itching of poison ivy, skin reactions involve more histamine—the body's allergy-causing chemical—than sinus flare-ups do. As a result, Claritin may not cut it.
Maximize it: Mix Benadryl with Tagamet, an OTC antacid.
ATHLETE'S FOOT
3. Lamisil AT
Lamisil AT inhibits an essential component of the fungal cell membrane.
BURNS
4. Solarcaine
It uses the king of the 'caines: benzocaine. In addition to being a powerful painkiller, benzocaine may be safer than other anesthetics, such as lidocaine, which can cause side effects, such as blurry vision and dizziness..
Maximize it: Before you reach for the benzocaine fire extinguisher, run your scorched skin under cool water to prevent blistering (don't use cold water, because the drastic temperature change can aggravate your epidermis).
CANKER SORES
5. Zilactin Cold Sore Gel
It leads a double life at the drugstore. Though Zilactin is marketed as a cold-sore medication, pharmacists chose it for canker sores because it contains benzyl alcohol. Like a liquid bandage, benzyl alcohol temporarily seals off the sore, protecting it from the irritation caused by eating. Minimize the irritation and you'll maximize the healing.
CARDIAC CARE
6. Ecotrin
It may save your life and your stomach, thanks to a special, slow-disintegration coating. "Ecotrin is dissolved and absorbed in the intestines, so it lessens the risk of stomach irritation that can occur with regular aspirin. A study in the journal Circulation determined that taking less than 100 mg aspirin daily offers the greatest level of cardiovascular protection, and that higher doses may actually increase the risk of heart trouble.
Maximize it: Don't take Ecotrin and drop an antacid at the same time. The antacid will cause the special coating to dissolve too quickly, turning Ecotrin into reg-ular aspirin.
COLD SORES
7. Abreva
Since cold sores are caused by the herpes virus, the only way to knock the disease back into dormancy is with an antiviral medication. Abreva is presently the only topical antiviral treatment available over the counter.
CONGESTION, NASAL
8. Sudafed
It's like nasal Drano. While most other decongestants only reduce sinus swelling, Sudafed also loosens the mucus, thanks to the inclusion of the expectorant guaifenesin. Pharmacists also point out that when Sudafed is combined with a spray decongestant, such as Afrin, it can prevent a person's ears from clogging up during air travel.
Maximize it: Add ibuprofen to your decongestion regimen. A new study published in the Annals of Allergy, Asthma & Immunology showed that stuffed-up subjects who took ibuprofen with pseudoephedrine—the main ingredient in Sudafed—had 22 percent less congestion than those who took pseudoephedrine by itself.
COUGH
9. Robitussin
This cough remedy edges ahead for what it doesn't contain as much as for what it does. Whether you choose Robitussin Guaifenesin to loosen the mucus in a congested chest or Robitussin DM to also help quiet a cough, neither formula contains alcohol. Alcohol swells bronchial tissues, which could make the cough worse.
CUTS AND MINOR WOUNDS
10. Neosporin
Why it won, three reasons: bacitracin, neomycin, and polymyxin.
DIARRHEA
11. Imodium A-D
Imodium A-D puts the reins on the runs by slowing down the movement of your intestines, whereas other products focus only on decreasing "fluid production." However, if the cause of your distress is payback from a certain Aztec emperor, reach for a bottle of Pepto-Bismol instead: The active ingredient, bismuth subsalicylate, can help kill off stomach bugs.
Maximize it: Drink a milk chaser. "Calcium increases your body's ability to slow the intestines,"
GAS
12. Gas-X
Gas-X contains the ingredient proven to stop explosive gas leaks fast: simethicone.
HEADACHE
13. Regular Strength Tylenol
Tylenol held a slight edge in a clinical cage match with Aleve.
Take medication early and you can stop the spasm from reaching its worst level.
HEADACHE, MIGRAINE
14. Excedrin Migraine
In addition to acetaminophen, it also has the proven pain-busters aspirin and caffeine.
Migraine sufferers who received two weekly 30-minute head massages reported decreases in headache pain.
HEARTBURN, ACUTE
15. Mylanta
Mylanta combines two balms for the burn: aluminum hydroxide and magnesium hydroxide. "They work immediately, but their duration is short.
Stick with liquid Mylanta.
HEARTBURN, CHRONIC
16. Prilosec OTC
It contains omeprazole, a chemical that can slow your stomach's acid pumps. Just one pill can decrease acid production, but a 2-week course is necessary for lasting relief.
HEMORRHOIDS
17. Preparation H
Hemorrhoids are just dilated blood vessels, which are best treated by chemicals called vasoconstrictors. Preparation H contains a vasoconstrictor—phenylephrine—while other brands have only anesthetics.
JOCK ITCH
18. Lotrimin AF
The fungus in your Fruit of the Looms needs to be treated differently than the type between your toes. The combination of the warm, moist environment in your underwear and the ease with which you can scratch the itch ups the odds of a bacterial infection. Enter Lotrimin AF.
JOINT PAIN
19. Advil
Advil owes it all to ibuprofen.
POISON IVY
20. Cortaid
Why won? - steroid. The Jason Giambi variety, but a topical steroid called hydrocortisone, which helps relieve both the itching and the inflammation that are caused by an ivy attack. Other topical creams, such as Benadryl and Caladryl, work only to soothe the itch.
Maximize it: Soak in oats. Before you rub on the Cortaid, immerse your itch-afflicted area in a mix of warm water and colloidal oatmeal for at least 15 minutes. One Australian study showed that patients who were treated with colloidal oatmeal for minor burns reported less itching and needed less medicine than those treated with another anti-itch ointment.
Generic equivalent: Hydrocortisone, 1 percent
