B


A


golf


course


named


Fox


Hollow,


which


has


won


an


award


for


its


relatively low impact on environment and sustainable wildlife.







Golf courses and the environment have historically been at odds. It’s


hard


to


reconcile


the


careful


grooming


and


excessive


water


needed


for


greens and fairways with conservation



and natural habitats. One case in


point,


Lakewood’s


Fox


Hollow


Golf


Course


had


its


construction


temporarily halted so some killdeer eggs can hatch. A pair of retail hawks


were also born during the construction of Fox Hollow. However, the golf


course


has


recently


won


an


award


for


its


relatively


low


impact


an


sustained


wildlife.


The


Golf


Course


Superintendents


of


America


say


Lakewood’s


27


-hole


Fox


Hollow


course


blends


well


with


Bear


Creek


Lake’s grasslands, and the land still hosts foxes, deer, great horned owls,


blue


herons,


coyotes,


and


other


wildlife.


Only


three


Environmental


Steward A


wards are given out each year, so Lakewook officials are pretty


excited about helping set the standard for golf courses with a soft touch.

1999




old school friends




2005





12 million







School




college




university






a


list


of


the


members




personal profile





other people’s details








Lives





about yourself






your self-esteem








School reunions






childhood sweethearts





relationships






Have you ever


wondered what your old schoolmates are doing now?


well, plenty of people in Britain do. One of the most successful Internet


ventures in Britain has shown how popular, and how lucrative, nostalgia


can be.




The website Friends Reunited was started for fun in 1999 by a couple


who were


interested to know what their old school friends were doing.


The


project


snowballed


and by


2005,


the


site


had


12


million


members.


One extraordinary fact is that Friends Reunited has never advertised, its


success is entirely due to word-of- mouth.




Y


ou can search for a school, college or university and find a list of the


members who were there in any year. Y


ou can also post a personal profile


showing what you are doing now, and read other people’s details.





Steve Pankhurst, one of the founders of the site, thinks that one of the


reasons


for


its


success


is


that


some


people


like


to


be


anonymous.


On


Friends Reunited, you ca


n snoop on other people’s lives without giving


away


anything


about


yourself


if


you


don’t


want


to.


It’s


also


an


opportunity to bolster your self-esteem by showing off to everyone


just


how successful and happy you are now, even


if


you weren’t while you


were at school.




Friends Reunited has also led to many successful school reunions, and


people meeting up with each other after many years. In particular, many


people


use


the


site


to


look


up


their


childhood


sweethearts


and


many


couples have actually rekindled relationships after contacting each other


through the site.





There


have


even


been


Friends


Reunited


weddings


and


babies,


and


Friends


Reunited


now


has


a


new


site


called


Friends


Reunited


Dating


especially


for


people


who


are


looking


for


love.


The


company


has


also


launched other sites, such as Genes Reunited, which helps people to find


long-lost relatives and build their family tress online.



So, whether you want to be nosy, contact old friends, organize a school


reunion,


find


your


first


love,


or


simply


show


off


you


success, Friends


Reunited is the site to visit.























D Beware hackers!


1. 75%


2. Juveniles, usually in their late teens to early twenties


3. They do it as a challenge.


4. A former hacker, now a security consultant


5. To fight the holes in the firewall -- the protection device between


different security systems


6. Because they can bring expertise that only hackers understand, a


holistic perception of computer systems


7. Because they are so in-depth within a system.


8. 90% or 95% effectiveness is better than not having anything at all.


9. A good security policy will protect you from an employment level up


to a system administration level.




Tapescript:


H -- Holmes T -- Teresa B -- Bevan


H: Let's talk about how widespread the problem is. Many people think the


number of companies or government agencies whose security is breached


is small. Is that the case or not?


T: No, I think anybody who has information online ... it's gonna be a huge


concern for anybody


. Mostly because if you've got information on these


websites, anybody can actually get into them. The thing that you need to


know is how to be careful. It's kind of like think of it as a security system


in a building,


let's say. If you have a security guard in the front, you're


protected in that area. Y


ou need to do that all around the entire circle, let's


say,


to


make


sure


that


your


entire


information


on


these


websites


is


completely protected.


H:


I


...


I


read


a


statistic


that


said


that


something


like


75


percent


of


companies online have been hacked, whether they know it or not. Is... is


that ... That's huge.


T: That is huge. And, in fact, it can be minor to major. Most of them are


usually on the minor scale -- that being, some information getting in. And


at this point in time, a lot of experts are saying that the hackers that are


going


into


these


sites


are


juveniles,


usually


in


their


late


teens


to


early


twenties. And most times, they're really just doing things as a challenge,


as a way to get in, because it's something that they can do.


H: Now, Mathew Bevan, who's a ... who's a former hacker, who became a


security consultant. Now ... now, tell us about that. This happens a lot?


T: This ... right now, this is happening a lot. Mostly because these hackers


that are young, juvenile children, or teens, as we have said, really know


the industry. They know the computer so well, even more so than a lot of


the


security,


you


know,


computer


systems


that


are


already


in


place.


They've


really


become


kind


of


an


asset, or


they


could


be


a consultant,


as ... as Mathew is, because they really know how they've got into them.


And


these


are


the


people


that


a


lot


of


corporations


can


actually


use,


because


what


they're


doing


is


they're


fighting


the


holes


in


the


firewalls


which


are


the


protection


device


between


the


different


security


systems


-and they're really kinda getting into the loopholes or the niches there. By


doing that this is great information that companies can use, because they


may


know,



that ... part of


that ... our


website


is


not,


you


know,


protected.


H. Y


ou were a hacker. And how important is that for you in your current


job, which is as a consultant for companies who fear hackers?


B. Well, in my current job, what I can do is bring expertise that perhaps


only


hackers


will


actually


understand.


It's


kind


of


a


perception


of


computer


systems, sort


of


a


holistic


overview.


And


sometimes


you


get


people who come from perhaps a sales background, and they move into


IT in a company, or, you know, they.., they may


just be programmers...


turned security experts. I'm not diminishing the expertise that they have,


but


sometimes


there


are


very


tiny


things


that


they


can


overlook,


just


because they're so in-depth within a system.
