Re: [Wlug] April Topic?

Another idea is open source robotics. I have a lot of experience with this at this point and would love to share.
One more idea would be talking about making and using custom Java JNI. have a library that's awesome but hate writing applications in C? JNI is a way of exposing these libs to Java. As an example I wrapped a v4l2 frame grabber and was able to get framerates 2-4 TIMES faster then OpenCV's frame grabber. Getting started with JNI is full of "gotchas" that keeps most developers away, which I think is a shame.

Re: [Wlug] Topic for April?

I would like to, by I do not have intimate knowledge of it. I know its an
improved version of gentoos baselayout 1 RC system. Its written in c instead
of scriptss, can do some parallel startups, but nowhere near anything like
systemd. And I can write simple init scripts for it. I, for one, would love
to hear more about systemd.

Topic for April?
by Tim Keller
Any ideas what people would like to do for a topic for April?
We'd talked about doing a distribution bake off... Does that still have any
traction?
Thanks,
Tim.

WLUG meeting idea - Distro comparison
by joel d
I am setting up a new laptop and trying to decide on which distro to go with...
Probably the same list of finalists as everyone else in no particular
order (Red Hat / CentOS / Fedora / Ubuntu / Gentoo / others).
Has WLUG done a disto comparison night meeting?
I think it might be interesting.
Each person bring in a laptop with their favorite mainstream distro
(possibly 3 or 4).
Spend 20 to 30 minutes on each, showing the major differences
(installs / apps handling / etc) and why they like it.
Probably not a new idea.
If it's been done of late then please disregard as I cannot make as
many meetings as I once could.
(This is due to my personal schedule not due to lack of interest.)

Re: [Wlug] Gentoo
by joel d
Got it.
"Ward, aren't you being a little hard on the beaver?"
I don't believe I shared my personal Gentoo opinion. Instead I mused
about a hilarious website and Gentoo's popularity growing and fading
like a wave...
Approx. 4 years ago I tried Gentoo once for a few days and discovered
it wasn't for me.
"Hi... My name is Joel and I'm a "Distro-XYZ" user." Sounds like a
support group intro to me.
No axe to grind, it is just my personal preference.
I prefer not to drink instant coffee also, so I merely go elsewhere
for my warm, slightly burnt, caffeinated goods.
As always your mileage can and will vary...
Actually I was mostly amused with the odd autos makes me want to do
the following to 15+ year old Honda Civic showing lots of rust:
put a rear wing with a half sheet of plywood held on with drywall screws
Spray the home-made wing neon yellow spray can to not match the car
(don't mask the car first)
remove the exhaust with a sawzall at the headers (loud with real flames)
leave a pair of custom exhaust pipe tips out the rear (leaving the
labling of Folgers coffee).
hood scoop made with a sawzall duct tape and a Cheerios box
replace all the wheels with 4 "donut" spares.
drive it up and down the street with a really bad car stereo
blasting "Tom's Diner".
Anyone have a spent, near end-of-life donor car in their driveway?
(on second thought, nevermind)

Wow.
I have never been to Gentoo is Rice before.
That guy has some issues but I missed why he was so upset ;-)
Was very entertained by the highly visually modified but still stock
underpowered autos.
Pics are a "People of Walmart" for the auto world.
That Gentoo's install numbers are fading:
everyone that wants it is upgrading as Jamie mentioned
dying due to Ubuntu adoption/popularity from the article
developers numbers dwindling from the article
no longer the cool distro for techies or average users (we want to
be cool too)
some other reasons...
or is it the end of it's technology "wave"
IMHO, most technology comes and goes in 1 to 8 year waves.
A technology wave example is the Slackware disto.
Who else remembers running Slackware (back when it was rather cool)?
Not sure I even know if they still release Slack anymore (I did just
go there and yup they do).
Three related waves which took longer admidedly were
centralized processing and dumb terminals of the simpler good old days
modern servers and intelligent desktops with processing power
back to virtual machines (and thin clients which are really akin to
fancy terminals)

Another distro to consider is Arch. I haven't used it, but it appears
to be similar in spirit to Gentoo. Looking at the beginner's guide,
https://wiki.archlinux.org/index.php/Beginners%27_Guide
it contains a lot of relatively low-level configuration stuff that one
would not need to know for a plug-and-play distro. So as a "learning
Linux" platform, Arch does looks promising.

Gentoo user here, too. Although I haven't done a fresh install in
quite a while, I just keep updating.
What I like best about Gentoo is picking and choosing which packages
to include and leave out, both applications and libraries. For
example, the other day I wanted to install "gtkpod", but I really
don't want to have Mono or QT4 installed on my system, for various
reasons. Doing a test install, I can verify that they are left out:
# emerge -ptv gtkpod
These are the packages that would be merged, in reverse order:
Calculating dependencies... done!
[ebuild N ] app-pda/gtkpod-1.0.0 USE="aac flac mp3 ogg -curl" 1,856 kB
[ebuild N ] media-libs/libgpod-0.8.0 USE="gtk iphone python udev -mono -static-libs" 975 kB
[nomerge ] media-libs/libgpod-0.8.0 USE="gtk iphone python udev -mono -static-libs"
[nomerge ] sys-apps/sg3_utils-1.30
[ebuild N ] sys-apps/rescan-scsi-bus-1.48 21 kB
[ebuild N ] sys-apps/sg3_utils-1.30 863 kB
[ebuild N ] app-pda/libimobiledevice-1.0.4 USE="python" 404 kB
[ebuild N ] app-pda/usbmuxd-1.0.6 57 kB
[ebuild N ] app-pda/libplist-1.3 67 kB
[ebuild U ] dev-util/cmake-2.8.3-r1 [2.8.0-r2] USE="ncurses -emacs -qt4 -vim-syntax" 5,310 kB
...
The USE= "-mono" and "-qt4" flags indicate that the listed packages
will be built without that support. Gentoo handles that by passing
the necessary options to "configure" when it builds the package, and
that is IMO the main point of using a source-based distribution.
If you *did* want support for mono, you could edit "/etc/make.conf"
(system-wide) or "/etc/portage/package.use" (package-specific), add
the "mono" flag (or remove "-mono"), and try again.
For better or worse, I think gentoo kind of peaked in popularity
several years ago. Related article,
http://news.cnet.com/8301-13505_3-10047439-16.html?tag=mncol;title
But it still meets my needs on several of my computers.
And finally, yes, I am aware of "http://funroll-loops.info/", and I
don't care. :)
