Companies Fight Endless War Against Computer Attacksby STEVE LOHR, New York TimesThe recent computer attacks on the mighty Google left every corporate network in the world looking a little less safe.Google's confrontation with China - over government censorship in general and specific attacks on its systems - is an exceptional case, of course, extending to [...]
I have number in file which contains date and serial number:
2013101000.
The last two digits are serial number (00). So maximum of serial number is 100.
After reaching 100 it becomes 00 with incrementing 10 which is day with max 31.
after reaching 31 it becomes 00 and increments 10... (31 Replies)

Hi,
I'd like to know how can I figure out my disk space area on AIX machine, for example to the situation of ( df -g ) which I have in my system :
the area used by (/opt/oracle) file system is (98%) now.
the free area on (/opt/oracle) is (0.75) now.
the total size in Gigabyte... (1 Reply)

pgmtexture(1) General Commands Manual pgmtexture(1)NAME
pgmtexture - calculate textural features on a portable graymap
SYNOPSIS
pgmtexture [-d d] [pgmfile]
DESCRIPTION
Reads a portable graymap as input. Calculates textural features based on spatial dependence matrices at 0, 45, 90, and 135 degrees for a
distance d (default = 1). Textural features include:
(1) Angular Second Moment,
(2) Contrast,
(3) Correlation,
(4) Variance,
(5) Inverse Difference Moment,
(6) Sum Average,
(7) Sum Variance,
(8) Sum Entropy,
(9) Entropy,
(10) Difference Variance,
(11) Difference Entropy,
(12, 13) Information Measures of Correlation, and
(14) Maximal Correlation Coefficient.
Algorithm taken from:
Haralick, R.M., K. Shanmugam, and I. Dinstein. 1973. Textural features for image classification. IEEE Transactions on Systems, Man, and
Cybertinetics, SMC-3(6):610-621.
BUGS
The program can run incredibly slow for large images (larger than 64 x 64) and command line options are limited. The method for finding
(14) the maximal correlation coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge.
