How do I play files with .ogg extension ??

I want to copy songs from my CD to the desktop.But whenever I try that it just copies the .cda files from the CD.But these can never be played??
This is the most common problem people encounter and the common notion about this is that the CD is encrypted or copy-protected.But that is not true.The Windows Explorer just shows it to you that way. There are various ways to do this.
The simplest of them is to download CDex software. And then convert the CD into .wav files.The only problem with .wav files is that they are huge.If you are short on space then convert it either to .mp3 format or .ogg format.My personal prefernce as mentioned above is .ogg. Here is how to conver the CD into .ogg files.After downloading the CDex software launch it.The go to Options-->>Settings and in the encoder tab and in the encoder drop-down select Ogg Vorbis DLL Encoder.And then your files will get encoded into the .ogg format.

Developer FAQ


Is there a Free/Open Source altenative to Microsoft .Net ??
Dot GNU. is the Free/Open Source alternative to Microsoft .Net.

Im a webmaster/web Developer.What is the best graphic format which I can use ??
I would replace all .gif files on my website with .png files.There are many reasons for this.One of the most important being that .png is the officialy preferred form of graphic format from W3. The PNG format is open source and no one has to pay royalty for the proprietary .gif format. As far as jpegs is concerned I would not replace them until W3 comes out with the PNP format.

Im a webmaster/web Developer should i be concerned for a law suit against my company for using gif's on my website ??
Yes there is a very good chance that Unisys can create problems for using illegal gif's on your website.Unisys has done this in the past.Here is a website which has details on this http://burnallgifs.org/.If I were to be the webmaster I would surely replace all the gif's with png.

I maintain a lot of computers for my company.Can i have a remote control tool for each one of them ??
TightVNCThis is by far my favourite tool as far as remote controlling computers is concerned.It is easy to setup.And easy to carry around.The file is so small that the viewer can fit on a floppy. Another thing really cool about this is that you can even remote control your machines from a browser.

Java sucks!!.Java is too slow.My applets load too slow.Is there a simple non-geeky way in which I can improve its performance ??
Go to the Control Panel.Then double click on the Java Control Panel. Copy this string to the -Xmx256M -mx256M the Java Runtime Parameters on the Advanced Tab. Here instead of 256M specify how much maximum memory you want to allocate to the VM.The reason why sometimes Java applets appear to run slowly is because it does not get the required Virtual Memory.In that case what happens is that it keeps on garage collecting and it is a time consuming activity.

When starting java apps manually give the the same command i.e. instead of
java classfilename
Type in
java -Xmx256M -Xms10M classfilename
In the example above i set the max heap size to 256Mb and initial start size to 10Mb.Change these parameters according to your system memory and definitely you can see that the Java apps will run much faster.
