You people don't get it, do you smile

Vas: Let me explain this again. I got an IIR low-pass filter inside AICA, aka Black Box. It uses two values as parametres for variable cutoff.
Even if I now have some figures as to how the magnitude vs frequency curve should look like, I still don't know how to construct the filter itself. It's only a guess that it's 2nd order filter - and if it is there are 6 internal coefficients that can be anything, really.
I need to figure out how the 2 parameters make those 6 coefficients. I can do that only by trying various combinations, not exactly very scientific method. With a design tool I could probably create a filter but it will only have one, set cutoff value. Still no clue how to make it variable with two parameters. Given a set of such filters I could possibly figure out what it is they have in common and focus on that. But that is simply too much work.

As explained before - someone who actually gets this stuff would probably know which coefficient to poke, just by looking at the curve. I just see that it doesn't match what I need, so now I can add something. Anything. Or substract. To any of the 6 variables. Good luck with that.

RB: Okay, this is in Polish but you will get the idea:

It's not about 35MB. It's about the 67 packages I don't need or have even heard of.
This is beyond sloppy. I mean c'mon - SDL? gtk2? Why not the whole KDE when at it?! What is the point of creating separate packages in the first place then?
This is just like the install process on the new distros - you can select "only the things you need" - to conserve disk space. Right. Pick one wrong program and the whole DVD will get installed anyway, as dependencies. It's like chain reaction. Linux sworn people laughing at Vista's size should really do du -hs on their /usr sometime.

I simply refuse to bloat my precious headless system. I'm pretty sure I would have to install much less devel libs when trying to compile gnuplot from sources (most of those I probably already have). And even then I'd never need any pm-utils. Sheesh.
