Your car key remote got wet, what now?

My car key fell into a street drain where it lay there for at least 5 minutes before somebody was able to fish it out. The first thing you need to do is remove the battery and dry out the electronic parts. I used tissue paper to blot out all visible moisture. When everything appeared to be dry, assembled the key back and tried to open the car. Fortunately, it worked. A couple of hours later, it didn't work anymore. When I checked the battery again, there was a little water and it appeared that there was still moisture inside the casing.

The best thing to do here is to find silica gel or a dessicant which you can find inside new shoes or bags. If you can't find any, you can go to a supermarket and buy a pack of rice crackers. I knew One One Rice Crackers had a large pack of dessicant inside. That's the one on the left below. I found the one on the right from a Case Logic bag. Just pack these together with the electronic component of the car key in plastic bag. Seal it and leave it alone for at least 2 days. The objective here is to remove all moisture from the electronics. My key worked again after this. I am still keeping the key with the silica gel bags at least for the week to be sure. Hope this helps.

A car remote key is a key used to unlock and start a car. It usually has a button to lock and unlock the car doors, and a button to start the car. Some car remote keys also have a button to open the trunk. Car remote keys are also called remote keyless entry (RKE) systems.

iReport Default Date Parameter

If you want to set a default date for a jasperreports parameter, you can enter the following in the default value expression of the parameter. new Date() However, if you wanted the default to be relative from today, for example, 3 days ago, you will need to do go outside of the standard java date libraries (Date, Calendar) because JR parameter does not allow you to have multiple statements. You can write your own utility package or you can use Joda , a replacement library for the JDK date and time library. To use Joda in iReports, you need to extract the jar file and add it to Options -> Classpath. You may also drop the jar file in iReports' lib directory. You will also need to add this library to your application or report server. For setting a default date 5 days prior from today, use this: new org.joda.time.DateTime().minusDays(5).toDate() or this if you want the time part set to the beginning of the day: new org.joda.time.LocalDate().toDateTimeAtStartOfDay().minusDays(5).to...

Migrating Moniwiki to MoinMoin

I had been using Moniwiki for our company for a while because the installation was quite easy as it was PHP based. However, I found out that document versioning didn't really work. It may have been a configuration issue but I took this opportunity to take a look at MoinMoin, as it was being used by Ubuntu and looked well supported. The server was running Debian stable and MoinMoin was in the repositories. Installing was simple using aptitude. Configuration was a bit more involved as it required copying and editing files. The new wiki site was pleasantly more responsive. The next task was to move the data in Moniwiki to MoinMoin. Upon inspecting the data repositories, I realized that Moniwiki stored the data in individual files with the WikiWord as the filename while MoinMoin organized that data with the WikiWord as a directory with the actual content under the revisions directory. I cooked up a quick script to migrate the data. I also ran the previous file through a 'tr' to...
