Have you noticed that you can find lots of stuff with 'apropos' that
doesn't actually have a 'man' page?  Here's an example:

# apropos gnutls_x509_crt_export
gnutls_x509_crt_export (3)  - API function
gnutls_x509_crt_export2 (3)  - API function

# man gnutls_x509_crt_export
No manual entry for gnutls_x509_crt_export

Thanks to you and Mike for your examples :)

Things that override global settings in make.conf, like package.mask, go
in /etc/portage. Things that override profile settings go
in /etc/portage/profile.

If in doubt, read man portage which explains all these files.

There use to be a central repo for many of the common gentoo admin scripts,
any idea where it is now that things have move to github?
(https://code.google.com/archive/p/genscripts/source)

I think there were others. The reason I like those, particularly for
new learning like python, is you get to see good and robust scripting
styles from the gentoo devs. Really helps when learning something new,
even if you have to figure out why things are written in a certain way.

ipython is some thing I want to learn by experimentation.

I do not think I need 'merge commits' for one offs, that is pulling
old codes into a development system.  Later on, when I get more aggressive,
pulling old codes to run on gentoo cluster, I might pester the list seeking
more advice.

All they need to do is provide the private key associated with the CPU
to the owner upon purchase.  In the case of a corporate computer, the
corporation gets the keys to the PC.

Most people wouldn't bother making any use of the key.  However, those
who are interested could sign libreboot or whatever with it and now
they have full control over their PC.  Indeed, they could then use
that control to ensure that nobody else goes tampering with their PC,
which is in fact the intended purpose of this feature anyway.

The problem is that Intel's solution effectively gives them a
back-door into everybody's PC.

You have to see this from a demand angle of the computing market.  I suspect 
Intel is just responding to market demand for 'better security'.  For big 
corporates better security means protection from internal (employees) as well 
as external threats.  Most CIOs would sleep comfortably in the thought that 
they can blame Intel when things go sideways and try to keep their jobs among 
the blame-fest and ricochets that ensues.  Of course our concept of security 
(who we trust with our computing) is orthogonal to your average CIO's out 
there who are invariably acting as a procurement agent.  Dare I observe, we do 
not really feature as a target market for Intel.

PS.  Thanks Max for sharing a good article on this topic.  I am interested to 
see if similar analysis has been performed on the AMD offerings.

I used pygit2, but there are a few different implenentations and
plenty of docs online in general.

Here is an example program that runs through a history and dumps a
list of commits and their metadata in csv format:
https://github.com/rich0/gitvalidate/blob/master/gitdump/parsetrees.py

There are some other scripts that retrieve blobs and manipulate them
in the same directory.  This was part of the validation of the git
migration, which uses a map-reduce algorithm to diff every single
commit in a git history and identify all file revisions (which creates
a cvs-like per-file history which can then be compared with results
obtained from parsing a cvs repository for the same information).  The
only single-threaded step in the process is walking the list of
commits - all the diffs can be highly paralleled.

I doubt you need anything quite so fancy.  As you can see from the
script pulling metadata out of commits and walking through parents is
pretty easy.

My example doesn't account for merge commits.  There weren't any in
the cvs->git migration.  Obviously walking commits with merges will
get a lot messier.

[gentoo-user] bluecherry:: video surveillance package

[James]

Hello,

So, 'zoneminder' has been in portage for a while now. The problem
is this open source software is not really aggressive with support
on the 'ip video cams' (h.264) that are available (at least last time I
hacked on zoneminder).


So Bluecherry seems to have opensourced quite a bit of their linux based
(fedora, ubuntu) video surveillance package [1].  Bluecherry appears to
leverage QT and mplayer [2].


If Anyone is interested in analog and ip (h.264) video surveillance, 
take a look at these and other related links to see if there is interest
in creating an ebuild for bluecherry client viewing software. We can also
discuss options for the video server, container deployment and other ideas.

No it's not. package.provided is for when you install a package from
outside of portage and want to let portage know it is installed.

You want to use /etc/portage/package.mask, with this entry

>sys-kernel/gentoo-sources-4.1.6

One of the disadvantages of this is that when that particular version is
removed from the tree, portage will try to downgrade, because you has
blocked an upgrade. To avoid this, copy the ebuild to a local overlay so
it is always available.

You'll also miss out on any security updates etc, but I guess you have
already considered that.

Huh?  What is this font group switching thingy?  I been using Gentoo for

course, I rarely print anything either.  Right now, I'm trying to figure

Have you tried building with 'icu' use-flag for libxml2, the gstreamer
