What are Java applets used for in programming?
Java applets are used to provide a self contained application or visually intensive experience to a user visiting a website. They are normally platform independent and as such the same Java applet can be delivered to users using Windows, Apple, or Linux.
Why do preists wear chausables?
The stole represents a priest's authority. The Chasuble represents love. The stole is worn under the Chasuble because authority is always at the service of love, not the other way around.
As an aside, I would be remiss if I did not draw attention to the fact that "overlay" stoles (stoles worn over the chasuble) tends to be favorite of progressive clergy. Little to they know what they are implicitly saying by doing that: "Love at the service of authority." Ironically progressive clergy are the ones who love to minimize priestly authority, yet their Liturgical action suggests otherwise!
How do you dump your girlfreind?
Ideally you stick to honesty. And you start by using the dreaded phrase "We need to talk....".
If you are as open and honest as you can be, you minimise the emotional trauma and long term fallout. Be brave, be direct. If you have fallen in love with Dee Jones, say "I have fallen love with Dee Jones". You may feel terribly terribly guilty, but don't let that interfere with your honesty.
The logical flow is to say that you are having second thoughts about getting married, say what the problem is, how you feel, apologise for breaking your promise and discuss the wrapping up of the relationship. Its not going to happen in one day - there will be several difficult meetings.
Fiance may try to patch things up. Don't try to keep fiance happy out of guilt. You want to get out, so make a clean break, don't leave fiance dangling.
A useful tip for better break-ups is to avoid laying blame on anybody. Accusations are inflammatory. Say instead how you feel about things.

power dependency
--
Reporting features like charts of a spreadsheet like Excel may not be available in RDBMS.
it is the power ratio in decibels
No, it isn't. dB on its own is a ratio.
But when dB has a suffix, the figure is an absolute measurement, not a ratio.
For instance, dBm is a measurement of power compared to 1mW.
0dBm means zero difference between 1mW and the measured figure. In other words the measured figure is also 1mW.
3dBm is 3dB greater than 1mW. -3dB is 3dB less than 1mW. etc.
Another suffix is W. 0dBW being 1 watt.
There are many more suffixes, some of which are used in only a few specialised cases.

What should you study to be senior oracle?
To be senior we assume you are already at least junior or entry-level oracle - yes? And by "Oracle" we further assume you mean an Oracle database administrator (DBA) versus say a senior Oracle product manager. If you meant a DBA, then may we assume you already are familiar with Oracle publications like "Oracle Database 11g, The Complete Reference" ISBN 978-0-07-159875-0? Have you read the materials published by Oracle online at oracle's web site? If so, then to be considered a "senior" Oracle person, you will want to a) have at least three to five years work experience with Oracle technologies, and b) become accomplished with some of the soft skills, e.g., working with system administrators, working with application developers and customers, documenting your work, working with management. These are skills that separate the senior professional from the beginner. Piece of cake - go get them and prosper!

What is a Checkpoint in oracle?
A checkpoint performs the following three operations:
- Every dirty block in the buffer cache is written to the data files. That is, it synchronizes the datablocks in the buffer cache with the datafiles on disk.
It's the DBWR that writes all modified databaseblocks back to the datafiles.
- The latest SCN is written (updated) into the datafile header.
- The latest SCN is also written to the controlfiles.
The update of the datafile headers and the control files is done by the LGWR(CKPT if CKPT is enabled). As of version 8.0, CKPT is enabled by default.
