The "security mask" parameter
I am a new Samba user so forgive my ignorance.
I am using Samba version 2.0.6 on HP UX 11 and I need to use the "security mask" parameter to prevent even the owner of a file from changing the read
only attribute
(by right clicking on the file from a Windows NT 4.0 desktop) if the file is read only (Unix permissions: 0440). This is what I have in the
"smb.conf" file:

Wish List: Extensions to the derivatives table
...be substituted with native ones for which deriv/deriv3 will work automatically. I believe that if you write your functions using log(a + 1) instead of log1p(a) or log(x) / log(2) instead of log2(x) deriv3 will work fine.
Thanks,
Avi

Wish List: Extensions to the derivatives table
The derivative table resides in the function D. In S+ that table is extensible because it is written in the S language. R is faster but less flexible, since that table is programmed in C. It would be useful if R provided a mechanism for extending the derivative table, or barring that, provided a broader table. Currently unsupported mathematical functions of one argument include expm1, log1p,

pt inaccurate when x is close to 0 (PR#9945)
...ect figures) for pt ranged from 10.7 to 13.4, while
pf(1e-8,1,df)/2+0.5
and
pbeta(1/(1+df/1e-8),.5,df/2)/2+0.5
agreed exactly with Maple, except for 21 and 90 df, where the LRE was
15.65. Clearly it would be quite easy to improve pt() for small values of
x.
