BeOS & Derivatives To understand what the BeOS and Haiku operating systems are, we first must remember that BeOS was developed with the multimedia user in mind. BeOS wanted to be what OS X has become today: an easy to use, attractive operating system. However, BeOS was a niche OS, destined for the media-hungry user. The percentage of audio and video applications available for Haiku is greater than the one in Linux, OS X or Windows, and the inner workings of the operating system were created in such a way, that the same multimedia passionate would find it easy to work with the user interface and files. Each application can interfere with other applications of its kind. A WAVE file selection can be dragged from a sound editor and onto the desktop, to create an audio file. Audio applications can interfere with each other via the Haiku Media Kit -- the corespondent of a Linux sound server. Applications like Cortex are a perfect example of how BeOS and Haiku deal with multimedia files: you can have more than one soundcard and use each one of those soundcards independently or separately. You can link one soundcard to the Audio Mixer, start a drum machine application and link that software to the Audio Mixer. If you want to output whatever you create with the audio application, all you have to do is drag the microphone and link it to the application's icon in Cortex.

1. The benefits of a database-like file system are not obvious to end users unless the operating system leverages it extensively. BeOS (and Haiku) were built to be run on such a file system, [...]

The BeFS is the biggest point I don't like on BeOS/Haiku.
In that filesystem there can be files with different sizes and every file can have unlimited numbers of attributes. And every attribute can have a unlimited size.
For example the program "peoples". It saves the addresses only as attributes of empty files. I can input in it a complete telephone-book, but when my disk-space come to an end, I search for the biggest files to delete them and not for the smallest one.
"StyledPad" mixed that: Write only text-files and the styling as attributes.
Also imagine computer-viruses and so on, which extends every file with lots of big nonsense-attributes. Or viruses, which writes itself as attribute to files, etc.


2. Object-Oriented API. On Be/Haiku, C++ is the primary low level interface with the OS. This is simply not applicable to Linux and never will be for a multitude of technical and political reasons.

And what is the advantage of it? There are not much kernel-developer on Haiku and Linux. Will an OOP-API mean, that more kernel-developer will come? Is it so more secure? Or have it advantages for the user?


3. Focus on multi-threading/responsiveness. [...] Linux concerning the balance between performance vs responsiveness makes it obvious to me that it is difficult to do both well. [...]

Linux have more driver then Haiku and exists additional in 64bit.
I think both is very important. For example graphic-card driver and so on. If Haiku don't close in. then it can not be faster then Linux. Video-playing, 3D-games and so on are driver things. There it don't help, that Haiku have a nice API.

That's only a minor UI issue: add a 'total file size' which would be the sum of the file size and the attributes sizes and your issues are solved.


If Haiku don't close in. then it can not be faster then Linux.

Depends a lot of what you consider 'faster'!!
BeOS was much more responsive than Linux..
Given that Linux still mostly focus on throughput and servers instead of desktop, it's quite possible that Haiku reproduce BeOS's superior responsiveness.

This problem is not exclusive of BFS. NTFS supports attributes too (they're called 'streams') since at least 10 years, and there are already viruses that take advantages of them.
In windows, though, unlike beos, there are not many applications (besides viruses/malware) which use the stream api (I'm not even sure there is a nice api to use)
