Caffeine - Google's new search engine

LONDON: Google Inc is working on a new test version of its search engine, which the company claims will be faster and more relevant than ever befo
re. The company has dubbed the new search engine "caffeine".

Look-wise, the new engine doesn't appear different, but its developers hope that the technology they have used will noticeably index new content faster.

Google engineers are said to have invited web developers to test the new search engine, and give their feedback. Matt Cutts, a principal engineer at Google, and Sitaram Iyer, a staff software engineer, have posted an entry on the company's webmaster central blog, appealing to developers to try the newly improved service and send them some feedback.

"For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google's web search. It's the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions," the Telegraph quoted them as having written on the blog.

"The new infrastructure sits "under the hood" of Google's search engine, which means that most users won't notice a difference in search results. But web developers and power searchers might notice a few differences, so we're opening up a web developer preview to collect feedback," they said.

A Google spokesperson added: ""Google is always working on new technologies to improve the quality of our search services. We hope this new system will improve search in the areas of speed, accuracy, and comprehensiveness."

Martin McNulty, director of search marketing specialist, Trafficbroker, who has tried the new version, said: "Google's caffeine is undoubtedly faster, almost twice as fast at times. It's like a Google GTi. Caffeine may be 'under the hood' but with this noticeable injection of speed it won't remain under the radar for long. As for accuracy, it's hard to say at this early stage but Google is clearly upping its game by including real-time results and more breaking news, as well as updates from the likes of Facebook and Twitter."

Most dangerous websites for your PC

MELBOURBNE: Internet security company Norton Symantec has come up with a list of
Top 100 Dirtiest sites, which could infect your computer with malware.
 
Malware is a software that can damage or compromise a computer system without the
owner's consent.
 
Natalie Connor, spokeswoman of the anti-virus company, said that even visiting any of the
named websites could expose a computer to infection and put the personal information
into the hands of unwanted people.
 
"What people don't realise is when you type in a website, you're bringing down information
on a page and with it could be malware," News.com.au quoted her as saying.
 
The list was compiled with the help of global data collected on Norton Safe Web, a site
that analysed websites' security risks.
 
Norton released a sample of the dirtiest websites:
 
 
The infected sites had on average 18,000 threats and 40 per cent of the sites had
 more than 20,000 threats, while 75 per cent of websites on the list were found
to be spreading malware for over six months.
 
According to Connor, most websites in the list had adult content with unprintable
 names, suggesting they contained hardcore pornography.
 
Some others sites include those on ice skating, deer hunting, catering and legal
services.
 
Hackers can apparently obtain personal information using keystroke-logging
 software from both PCs and Mac computers. Source:infotech.indiatimes.com

Power Management in IT

What is Power Management in IT means ?

The IT industry developed the power management or "sleep" feature that improved the energy efficiency of office equipment like computers, while helping to extend the life and performance over the long run.

Today, virtually all office equipment manufacturers now integrate power management features into the basic design of office equipment, (computers, monitors, printers, faxes, copiers, scanners, and multi-function (all-in-one) devices).

When is power management working?

Power management works when you stop working. PM is engaged when you leave your computer idle for a set amount of time (a time the user can adjust) and the monitor goes black. The monitor should also go black after a screen saver has been on for some amount of time. However, when the screen is dark, or black, it's not really off; it is simply sleeping, cooling down and reducing wasted heat at a time when full power is not required. A simple move of the mouse or touch of the keyboard will cause it to power up. Many new computers now come with a special sleep button on the monitor or keyboard, so with a quick touch, the computer immediately powers down and sleeps. This feature is particularly popular in laptops but is finding its way into desktop and deskside designs.

Enabling the PM features of office equipment can reduce operating costs and serve as an important part of any organization's environmental program.

"Business users will benefit from lower average power consumption – up to a 60 percent

average power saving…Users will no longer be required to make critical trade-offs
between system performance, connectivity and efficient power saving."
 - David Chan, Strategic Initiatives Manager, Intel Corporation

"Continual improvement in energy efficiency of IBM's computers, monitors, and printers

through design and power management features is a key ingredient in helping our
customers reduce the total cost of ownership…this also helps the environment by
minimizing demand on electricity."
– Mary Ann Flandera Christie, Program Manager, IBM

Why to use Power Saving Mode or switch off the PC when not in used ?

PC Power Down powers down a PC if it has been left on and switches off the power to the computer's peripherals including the monitor at a scheduled time each day saving electricity and unnecessary carbon dioxide (CO2) emissions.

  • Reduce fire risk associated with leaving electronic items powered and unattended .
  • Reduce CO2 emissions by 750kg* a year per PC (the equivalent of you taking 7 return flights from London to Paris).
  • Improve computer security: PCs cannot be attacked when powered down.
  • Extend life of your PC and its peripherals.
  • The PC Power Down block comes with surge protection.
  • Save the Planet - Using PC Dower Down to eliminate electricity wasted by having a computer powered up when it is not needed will save 0.43kgCO2/kWh, that equates to 0.75 tonnes of CO2 emissions that would be created in generating the wasted electricity.

  
Some Facts :
 
  • A typical 150-watt PC consumes about 876 kilowatt hours per year.
  • A typical PC Consumes 150 Watt / Hour.
  • Working Hours: 8 Hours / Day
  • If machines are not switched off, PC ON time: 24 Hours / Day.
  • Working Day's in a Year: 220 Days.
  • Power Consumed per PC per Year ( 8 hours / Day ): 150 Watt / Hour * 8 Hours / Day * 220 Days = 264 kW.
  • Power Consumed per PC per Year( 24 hours / Day ): 150 Watt / Hour * 24 Hours / Day * 365 Days = 1314 kW.
  • Energy Charge (Paisa /kWh): 400 Paisa /kWh
  • Annual Cost ( 8 hours / Day ): 400 Paisa /kWh * 264 kWh = Rs. 1056
  • Annual Cost ( 24 hours / Day ): 400 Paisa /kWh * 1314 kWh = Rs. 5256
If the Machines are switched off after 8 hours of working, we are able to save 80 % of electricity bill.
