- Sure is. My mom and her sisters, during the war, would do the same thing; heat up rocks, wrap them up and sleep with them. The rocks would hold the heat. Kinda like a hot water bottle. It was the only way the could stay warm - if they were lucky enough to find enough wood for the fire that day.

- most viper systems have a valet or disable switch. If you have the key you should be fine. This alarm switch should be a very small silver switch or a red push button. It will normally be located somewhere out of site underneath the steering column, maybe even around where your feet go, occasionally they get mounted near the fuse block or in the ashtray. First find this switch. Then if it is a flip switch- flip it opposite whatever way you find it. Then turn the ignition ON and OFF wait 5 seconds and ON and OFF again. It should start normally. If you have a red or black pushbutton then push and hold it while you turn the ignition ON and OFF then let go of the button and your car should start normally.(you may have to do this procedure more than once) I have a few more techniques if this doesn't work, you can email me direct if so.
- Q: i have a fire extinguisher explosion and is my food still good. there is white powdery substances covering all of it.
- Drive like a white man in accordance with the weather conditions and with proper snow tires and you do not require studs. And studs are designed primarily for traction on ice, not deep snow. Even when studs were legal in my area I never utilized them. I simply drove in a sane manner when the weather turned. In 45 years of Winter driving I have only required a tow truck once. And that was only because my vehicle of choice was upside down from driving like a jerk.
- Q: why did all my fire alarms go off for 3 seconds and shut off? and the power did not go out?
- Yes, vapor lock is a symptom of either a clogged fuel filter, or a failing fuel pump. The fuel filter may be something you can do yourself (if you can trust yourself not to set the thing on fire). The other will require a mechanic. And it could be things other than vapor lock too. [EDIT: There is water coming out of the tailpipe. Are you losing coolant? If so, you've got a good answer, either blown head gasket, or a cracked block. As engine rpms go up, so does cooling water pressure When an engine is cold, and the exhaust system is cold, you will have some condensation for a while. This is normal, and not symptomatic.]
- Q: Something is screwed up with my Zone Alarm. I keep getting some error message that says I'm probably missing a necessary root certificate. Now what the heck does that mean? Well anyways I tried to delete my ZA, but I can't, that damn error message just pops up. Than I tried to install a new and updated ZA, but once again that error message pops up. Who knows what is going on here? What root certificate are they talking about?
- Install a file-sharing system that requires authentication, preferably using SSL or other crypto to protect credentials in transit, and only issue credentials to people whose identity you have checked. Use access control lists to limit access to files and folders to certain people or groups. Protect files by doing regular backups, and by using version control like SVN to preserve earlier copies. Implement an audit trail in logging to record which users have accessed or changed files. Uisng a firewall to control access based on network address, e.g. only locally-connected users, is a useful second line of defense. In a simple home network on WiFi, using a good WPA key and only giving it to people you trust is probably good enough for most people, in combination with a firewall or NAT rules that prevent access from the public Internet
- Q: How to change the alarm alarm time?
- If the microcontroller is done, and that is not changed.
