Comment on What is the real development costs of Debian GNU / Linux – How much costs the development of a Free Software projects by admin.
Software cost estimation is tricky business even when all the variables are known (which we certainly don’t have). One thing to remember is that COCOMO was created to model large institutional projects, which often don’t compare well with distributed open-source projects. Beyond just development time, COCOMO is meant to include the design, specification drafting, reviewing and management overhead that goes along with producing quality software.
This model seems to be most accurate with mature, large projects. Young projects with little activity are typically overvalued.

Just as a matter of comparison it is interesting fact to know, the approximate number of lines of code in Microsoft Windows (data obtained from Wikipedia):
Year Operating System SLOC (Million)
1993 Windows NT 3.1 4-5
1994 Windows NT 3.5 7-8
1996 Windows NT 4.0 11-12
2000 Windows 2000 more than 29
2001 Windows XP 45
2003 Windows Server 2003 50
You see microsoft Windows contains a way less code compared to Debian Linux 🙂
However while comparing it should be considered Debian basic core with Gnome will be far less than the overall 419,776,604. Probably it will be just few million lines of code.

Christ is Risen Eastern Orthodox Resurrection Paschal Greeting in Different Languages
Hi Stan,
I guess you cannot read the writtings on the icon as it is in cyrillic.
This is not Saint Mary and Saint Peter but Adam and Eve written in cyrillic on top of the icon.
Actually in orthodoxy it is a requirement for the depicted personalities, especially saints to have
written on the names of the saint and have the Halo. If you look closely at the picture you will notice
the two Adam and Eve are missing a Halo. The only person with a Halo in the icon is Saint John the Baptist.
Best Regards

Install and configure rkhunter for improved security on a PCI DSS Linux / BSD servers with no access to Internet
–rwo, –report-warnings-only
This option causes only warning messages to be displayed. This can be useful when rkhunter is run via cron. Other options may
be used to force other items of information to be displayed.
–sk, –skip-keypress
When the –check command option is used, after certain sections of tests, the user will be prompted to press the return key
in order to continue. This option disables that feature, and rkhunter will run until all the tests have completed.

As rkhunter check, can be pretty annoying and ask you to press keypresses multiple times and spit you a lot of unnecessery data a very good useful option arguments are:
–rwo and –sk
# rkhunter -c –rwo –sk
Warning: The SSH and rkhunter configuration options should be the same:
SSH configuration option 'PermitRootLogin': yes
Rkhunter configuration option 'ALLOW_SSH_ROOT_USER': no
