　　Kids!Come have a ball!Or 60,000 of them!There’s a new type of business franchise that is appearing in shopping malls and neighborhoods across America offering pay-per-use indoor playgrounds ,which feature toys ,games ,supervised fun and a workout that doesn’t break the family bank．

　　As public playgrounds grow increasingly worn and dirty, the for-profit centers offer clean, safe supervised activity as well as a variety of challenging exercises to develop youngsters’ physical fitness, usually for a fee of around 5$ an hour．“Playgrounds are dirty ,not supervised,” says Dick Guggenheimer ,owner of the two-month-old Discovery Zone in Yonkers, N.Y., part of Kansas City-based chain, “We are indoors; we are padded(铺上软垫)；parents can feel their child is safe”．

　　In order to satisfy the need of two-earner families ,the new franchise stayed open in the evenings ,long after traditional public playgrounds have grown dark and unusable．However these new playgrounds are not meant to be day-care centers．Parents are expected go stay and play with their kids rather than drop them off．But several also provide high-tech baby-sitting services．At some of the Discovery Zones, parents can register their children in special supervised programs, then leave them and slip away for a couple of hours to enjoy a movie or dinner．If there is a problem ,Mom and Dad are called．

　　The most fun of all, though, is getting to do what parents used to do in the days before two-earner families and two-hour commutes; play with their kids．That ,at least ,is old-fashioned, even at per-hour rates．

Smartphone Security Blankets

　　Security-for the information on your smartphone, as well as for the phone itself-is a hot topic these days．The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe．

　　When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app(application program)from Apple that allows you to visit a website and see your(lost, stolen or misplaced)phone on a map．You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data．

　　Android does not have an exact equivalent, but there are plenty of alternatives．A free app called Lookout offers the find-my-phone feature．The paid version allows you to wipe the data from your phone remotely．

　　Then there is your coffee shop's WiFi network．Anyone with minimal technical expert skill can snoop on(窥视)people using shared wireless networks, harvesting passwords and other personal data．Lookout's apps will caution you when you've logged on to an unsecure network, but cannot protect you once you're there．

　　In order to protect yourself on such networks, you can use a virtual private network, or V．P．N．This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks．It also keeps websites from tracking you and, if you're traveling, allows you to get access to sites that may be blocked in other countries．

　　If you have an iPhone, the simplest V．P．N．app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing(浏览), as opposed to other V．P．N．apps that require you to start them up manually．This matters, because even if you decide you want a V．P．N．app, you want to spend approximately zero time thinking about it．For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning．I found myself having to turn the app on and off sometimes, which involved setting my phone constantly．

　　If even reading about the settings on your phone drives you crazy, then it is probably best to stay away from a V．P．N．app．But if you're the type who can't resist checking your bank balance from your corner bar, the hassle may be preferable to the risk．
