Then I want to convert the file to a different bitrate using ffmpeg, but unfortunately ffmpeg resets the start time of the video, which breaks my application, since it needs to know the start time of each video (and these of course should be diffe...

I've tried achieving a hover/selected color change for a particular field, but I'm thinking jQuery is the answer. I've looked into some button click tutorials, but maybe I'm not just seeing it or doing it correctly. The idea here is that when a user hovers over a Headline, the background color changes, when they click the headline to ex...
I have a class which is serialized to and from an XML file when the user decided to open or save.

I've got a simple login system using PHP sessions, but just recently it seems that if you visit pages not in a certain directory (/login/) you will always be flagged as not logged in, even when you are. It seems that my session data is being lost when I change directories (say, to /login/user/). I don't think I've touched the code myse...

I have an AJAX file uploader script (which functions correctly) that I want to run each time the file input value changes. Here's my working code: <input type="file" ...

I am currently developing an application that will store data in an SQLite database. The database will have much more read- than write-access (in fact, it will be filled with data once, and then almost only reading will happen). The read-performance is therefore much mre important. The schema I am currently developing is very likely to c...

At the backend we have a high volume Teradata database.We expect some other applications to be constantly feeding in data into this database. Now we are wondering about how to feed in the changes from the database ...

We have PITR setup and WAL shipping enabled. We would like to change the password for the user postgres. The process is simple enough. However, since we cannot connect to the SLAVE how would we make sure all passwords are in synch? Would temporarily disabling WAL shipping allow me to connect to the slave to change the password there? I c...
