Hello, All! There are some sources of pseudo network interface driver develkoped for 2.2.x kernel. I have to port it onto 2.4.x kernel. I have explored the structure 'net_device' from linux/net/netdevice.h, there are few major changes. The main problem for now is - how to check that interface is ready to transmit data (in 2.2.x 'tbusy' field was used fot this and function 'test_and_set_busy' checking the 'tbusy' state). But thus field was removed from 2.4.x kernel, and now you should use the function 'netif_start_queue' or 'netif_stop_queue'. How can I check in 2.4.x that device is not busy and ready to to transmit data? Thanks in advance. With best regards, Roman Mashak. E-mail: mrv@tusur.ru

Is there a simple way to get Maple to convert x^(3/2) + x^(5/2) to (x+x^2)*x^(1/2). I am willing to assume(x>0). Maple does recognize these as being equal: > p:=x^(3/2)+x^(5/2): > q:=(x+x^2)*sqrt(x): > simplify(p-q); 0 Here's a clumsy way to do it: > p:=x^(3/2)+x^(5/2): > assume(t>0): > subs(x=t^2,p); > simplify(%,{t^2=x}); > collect(%,t); Is there something simpler?

Hi , I hope this isn't too trivial to ask, but I'm evaluating a polynomial that involve lots of terms like x^2y^2z^3, and although I can use the power function pow(a, b), I wonder if just writing x*x*y*y*z*z*z for example wouldn't be more efficient than pow(x, 2)*pow(y, 2)*pow(z,3).

Hi Since the power is more relevant to analyze than the amplitude I have come = up with the idea of using signed square ss(x) =3D x^2 for positive x and -x= ^2 for negative x or ss(x) =3D (x^2)^(1/2)*x =3D sgn(x)*x^2 Instead of analyzing the power as the square of the amplitude the signed po= wer could be used instead. This would preserve more information of the orig= inal signal. The original amplitude signal can be recreated from the signed= square power signal with signed square root. I can imagine signed square to be applicable to codec evaluation and signal= compression since the power of the signal is more relevant to compress tha= n the amplitude. It would be easy to make a simple test with Scilab and some sound or image = file. Would it be possible to analyze this theoretically with Karhunen-Lo=E8ve th= eory?

May be the help for linspace should change? It says: "LINSPACE(X1, X2, N) generates N points between X1 and X2." Notice, it says BETWEEN. But when I ask for 2 points, between 2 and 2: ---------------- EDU>> linspace(2,2,2) ans = 2 2 --------------- May be mathematically this is ok? i.e. there are infinite points between the point and itself? (on the real line), but from programming point of view, it is confusing. no? --Nasser Maybe it should say "generates N points between X1 and X2, inclusive." What did you expect to get back as an answer from issuing linspace(2,2,2)? I didn't understand your statement "there are infinite points between the point and itself?" How do you have an infinite number of points between 2 and 2? I can see an infinite number of points between 2 and something that's not itself, like 2.00000000000000001, but if they are absolutely perfectly identical how are you getting an infinite number of points?

Hi, ArcCos[x/Sqrt[x^2+y^2]] and Pi/2-ArcTan[x/Abs[y]] are the same. But I can not get the first expression be simplified to the second one.

FullSimplify[ArcCos[x/Sqrt[x^2 + y^2]] - ( Pi/2 - ArcTan[x/Abs[y]]), Element[x, Reals] && Element[y, Reals]] I'm wondering if there is any walkaround to do this simplification.

I think Indep values must be xand y at the same time but the calculator does not allow me to put x and y together, why? Help please... Thanks everybody for your time.

Hello all, I tried the first time my wxMSW application on Linux with wxGTK and I experienced following issues und would like to know if it is a GTK limitation or wx' one: - Loading .xpm - files in .xrc - resources doesn't work (no handler) But perhaps in a toolbar wxBitmap("myIcon_16.xpm") works. - No "real" MDI support and no StatusBar support for Childframes (this _should_ be documented) - wxTE_RIGHT does not work for wxTextCtrl - wxListCtrl in wxLC_ICON - Style aligns the icons to the left. I know that's a Win32-Feature to align the icons "centre" but Evolution also supports this (perhaps Gnome feature?)
