Computers and Lasik Eye Surgery

Lasik Eye Surgery has been effective for quite some time now, but is constantly  becoming even more precise due to increased computer technology.  The software used to aid in eye surgery  can easily calculate the clients cornea and in turn adjusts to that patients eye.  It can even correct vision abnormalities beyond astigmatism, farsightedness, and nearsightedness.  Before the new software developed by the University of Rochester Norogram, 20% of patients were still a bit farsighted, but with the new software, that statistic drops to 2 %!

A pro about this new software is that the patients do not need to come back in the future for further work.  A con about lasik is that some people are not good candidates for this surgery because of things such as rheumatoid arthritis, keratoconus, or active herpes.

This is a huge step for technology to be able to help people not have  to wear glasses or contacts.

 

DO you think that lasik is a valid and safe way to help with eye sight and other abnormalities?

GREEN COMPUTING

We all know that these days everyone is trying to make the world better and to help preserve the environment.  Now there is even ‘green computing’ that is helping with the reduction of energy that computers use.  A definition of green computing from the website I found online that is also attached is ‘the study and practice of efficient and eco-friendly computing resources, is now under the attention of not only environemntal organizations, but also businesses from other industries.  It has been found that going green is good for their public relations AND  it also reduces cost  – so it’s a win-win solution!

Green technology is very keen on reducing the environmental impact of industrial and innovative technology on the Earth because it is expanding so rapidly.  Some of the ways that have been introduced for technology are: sun, wind, water, sugar and others.

Computer viruses

Unfortunately there are many computer viruses that can affect  anyone’s computer.  Anti-virus companies are noticing a major jump in the purchases of their software. 

There are SO many computer viruses: Zotob, Mytob, Netsky, Sober, Gibe, and Mydoom to name a few.  The most reported computer virus is Netsky.  Sadly, more than 90% of computer viruses are undetected!  There are about 60,000 different viruses out there at this point. 

A well known virus is called The Sassar Worm, which cost about $500 million worldwide.  That is devastating.

Some good news is that some virus creating people are being arrested so the virus cannot be a harm to any more computers.

Optical Scanners in the Election!

What an exciting election…  I sure hope you voted!

Optical scanners were brought into some states polls and over 1 BILLION dollars was poured into the new voting machines.  On voting day, almost 90% of voters cast their votes optically or electronically also known as DRE (Direct Recording Electronic) devices.  Only 11 counties out of 3,117 will be using punch cards for the election.

There are some downfalls to this new electronic voting, as with everything.   Some machines crashed, memory cards will be unable to be read, touch screens will flip votes,  and the software will have glitches as well.   However, the University of Missouri study in 2004 that for punch- cards ballots, the error was just an impressive 1%.

In 5 states in America, there were problems reported with optical scanners.  The states were Florida, S. Carolina, Ohio, Washington DC, and New Jersey.

New Technology for Lasik Surgery

Mostly everyone knows what Lasik Eye Surgery is.  Many people are turning to Lasik so they never have to go through the hassle of wearing glasses or putting in contacts everyday.   Recently, eye doctors (Opthamologists) have made new software that can analyze the shape of the cornea which will re-adjust the laser during surgery to  make an even more customized surgery. 

It is so amazing that in a few minutes, this surgery had a patient named kelli Tette saying, “I can see so much better than I ever did even with my glasses or contacts on.”    With the ‘old’ Lasik Surgery, about 20% of patients were still a little farsighted after surgery,  but now that percentage drops to 2% and they are also less likely to need a touch up after the first one.

wall street ‘tsunami’!?

I was looking on Google News for my blog post for today and immediately was drawn to this article.

I found tha some so-called bad data hurt Wall Street – not good.  Alan Greenspan called it a once in a century ‘tsunami’.   He blamed the ‘tsunami’ on inadequate data.  As you probably know, computer technology is a very important part of Wall Street in more ways than one.  Crashes in computers do not happen very often with the technology that Wall Street has, that is why it was such a problem.

 ”Business decisions by financial services firms were based on “the best insights of mathematicians and finance experts, supported by major advances in computer and communications technology,” Greenspan told the committee. “The whole intellectual edifice, however, collapsed in the summer of last year because the data inputted into the risk management models generally covered only the past two decades a period of euphoria.”

  – THe above quote is from The New York Times 10/23/08

Those working at Wall Street are trying to figure out how to fix this and how to prevent it from happening again.  The only suggestion as of now is to have ‘more aggressive law enforcement.’

blog #2!

Did you know that Apple has come out with a new computer/laptop!?

Neither did I.  This new notebook has a low new price (lower than the usual price for macs that is) and doesn’t lack any of the attributes that mac people love.  This new laptop starts at $1,200, which is still more than the laptop that I bought for college.

Apple also came out with a new 24″ computer with all of the amenities that a mac should and usually does have.

As for another mac fact, the iPhone was named 2008 Gaget of the Year.
