Mechanics set the record straight

Bankrate Canada - Fiona Wagner
Auto mechanics hear it all -- folklore, urban legends and Internet advice gone bad. Jim Kerr, a master automotive mechanic in Saskatoon, Sask., and technical editor for CanadianDriver.com, once had a customer ask him to replace the winter air in his tires with summer air (in case you're wondering, air is air -- it never goes stale or out of season).

He's also heard of people pouring boiling water over a battery to warm it in cold weather (you need to heat it the inside of the battery, not the outer shell) and using a pair of pantyhose in place of a fan belt (he's tried -- it doesn't work.)

Microsoft WindowsXP服务详解

16
推荐1、Alerter
Alerter(警示器)服务的进程名是Service.exe(即启动这个服务后在后台运行的进程名称,可以通过任务管理器看到,下同)。Alerter服务的功能是,WinXP将系统上发生的与管理有关的事件以警示(Alert)信息传送至网络上指定的电脑或用户,例如当发生打印错误或硬盘即将写满等事件,这类警示信息由WinXP的警示器服务(Alerter Service)收集、送出。尽管Alerter依存的服务并没有Messenger(信使)服务,但Alerter服务必须依靠后者才能送出信息,故在启动Alerter服务后还必须确定Messenger服务也在工作状态,而接收的电脑也必须启动Messenger服务。由于Alerter服务运行后,服务是用户可以发送“弹出(Pop-up)”信息给其他用户,这些信息有可能被攻击者用来实施攻击,如诱骗用户修改口令等,从而造成安全隐患。同时该服务使得用户账号泄漏,也有可能被攻击者利用来进行口令猜测攻击。所以对于家庭单机用户,甚至对于绝大多数小型的局域网来说,这个功能是完全可禁用的,不仅节省了系统资源和加快启动速度,也提高了机器的安全性。

All your computer security precautions are worthless
By Christopher Null
.Install your Windows Updates. Update your antivirus software. Scan your system regularly. Keep religious backups. It's all good advice -- and it's advice that I give to readers on a near-daily basis.

And maybe it's all meaningless.

MIT researchers are warning that it doesn't matter much what security measures you take with your computer. If someone wants in, they're getting in.

There is a line in my document that I can't delete

There is a line in my document that I can't delete because I can't select it. How did it get there, and what can I do about it?

Although there are other possibilities, most likely what you're dealing with is the paragraph border that Word creates when you type three or more hyphens (-), underscore characters (_), equals signs (=),asterisks (*), tildes (~), or hash signs (#), and press Enter. By default these characters are converted to a thin, thick, double, broken, zigzag, or thick-and-thin border at the bottom of a paragraph.
