RE: [Wlug] Fw: RE: show
by Keller, Tim
Well, I kind of took it on this tact. My wife really doesn't care about
linux, nor windows. When she sits down in front of the computer, she just
wants it to work as expected. Past that, she plays a few games, but mainly
it revolves around surfing the web, reading email, etc.
With that said, I think that the argument for linux has to be made on a
couple fronts.
Firstly, cost and freedom. Explain to people why linux is a better choice
than the perceived "free" copy of windows that came with their computer. I
think we should definitely explain the microsoft tax.
Second, security. Make it a point of explaining that linux is impervious to
the many worms and viruses that are running around the internet. Though we
should also caution people that a poorly configured linux box is just as bad
(if not worse) than an bare unpatched windows machine.
Past that, we should talk to the availability of software for linux.
Later,
Tim.

Makes sense to me, Tim. Easy replacement is the selling point, and in
some ways it's been the stumbling block to my converting entirely to
linux. I still use Windows for a couple of tasks that either can't be
done in linux (yet) or I haven't figured them out in linux yet
(unsupported scanner).
Show people that they can do the things they need to do with a minimal
amount of effort and without having to pay microsoft, and there will be
plenty of converts. Most of the things that most people do with their
computers can now be done in linux without having to read a manual, and
people need to know that.

That is cool that pfSense can do wireguard!

Re: Uptime!
by Mike Peckar
According to the Guiness Book of World records, The computer system that
has been in continual operation for the longest period is the Computer
Command System (CCS) onboard NASA's *Voyager 2* spacecraft. This system has
been in continuous operation since the spacecraft's launch on 20 August
1977. Voyager 1's CCS uptime trails it by a couple of weeks and both are
still going.
Each Voyager has two CCSs, two Flight Data System (FDS) computers and two
Attitude and Articulation Control System (AACS) computers, but the FDS &
AACS do not operate continuously. The CCS's have two 18-bit word, interrupt
type processors with 4096 words each of non-volatile plated wire memory
amounting to 69.63 kilobytes. They execute about 81,000 instructions per
second and transmit data back to Earth at 160 bits per second. They were
originally programmed in Fortran 5.

Frank,
Please reserve one of the good ones (free as in free beer) for me.I would like to pick it up before 12 noon tomorrow (Thursday 5-19) if I could.Otherwise I might not be able to come until Friday.Please tell me where in Westborough your company is located.

Re: [Wlug] (no subject)
by John Stoffel
Tim> Here's my .02 cents on building a machine.
I'm going to chime in here as well with my thoughts on system building
options.
0. Motherboard.
- integrated vs discrete graphics.
This is a toughie. For a home server, I'd go integrated. Heck,
I'd try to get something with a serial console so I could manage it
without a KVM, since ideally the system will be headless most of
the time and just serving data, etc.
- PS/2 mouse/keyboard ports or all USB? Depends on what you have
and whether you're replacing it all or using existing stuff.
- PCIe slots.
- unless you game, don't bother with lots of x16 slots, maybe
two, but get as many slots as you can. If you have legacy PCI
cards you want to use, that's another factor.
Think long term expandability. Remember that PCIe x1 cards will
fit in x4,8,16 slots, they just won't get the performance
advantage. Doesn't go the other way though.
- SATA ports on board. I'd get a bunch if I can, since if you
ever load up the system with lots of drives, you want to put off
the day you need a PCIe SATA board. This is why I like x4 or x8
slots for the future.
0b. Network
Gigabit by default. Upgrade your home switch too. If you can,
get dual Gig ports, but don't sweat it too much otherwise.
- skip wireless for a desktop, unless you absolutely need to put
it somehwere with only power access. Then get an 802.11n card for
the system and upgrade your Access Point (AP) as well.
Tim> 1. Memory. You can never have too much of it. I'd say try to
Tim> get a board that'll do 8GB with the expectation you'll be there
Tim> at some point.
Absolutely. Spending more on memory is a better idea than more on a
slightly faster CPU. Don't sweat DDR2 vs DDR3 at this time unless
you're seriously number crunching.
Tim> 2. CPU: go duel at a minimum. If you could swing a quad I'd say
Tim> go for it.
Dual. Sorry, being pedantic. But I agree. I also lean heavily
towards AMD because I like that they've been doing documentation drops
on their GPUs, and because I want CPU vendor competition, not just one
vendor.
But as a suggestion, graph CPU speed vs $$$ for a family of systems
and look for the sweet spot, which is where the price goes up sharply
for just a small gain in speed.
Do the same for the number of cores, and put them on the same graph.
Think about cache, etc.
Right now, the Triple Core AMD X2s looks nice. For a set amount of
$$$, I'd personally go with more cores vs higher speed.
Also, NEVER overclock. It's just not worth it. Yeah, it makes you
feel studly, but esp for a home server, you want stability and low
power draw, since it will be on all the time.
Oh yeah, think about power disappation. Try to get the lowest wattage
parts you can. Another reason why more cores, slower clock freq and
lower thermals can be a win.
Again, think about whether you really need to spend $100 more to get
200 Mhz of speed. Think how much memory you could buy instead! Or
disk space.
Tim> 3. Video card: Get something that will do HDMI and is capable of
Tim> duel head. I've got a Nvidia GeForce 8400 GS with 512MB of video
Tim> memory and it cost me a whopping 40 dollars!
The thing to think about is whether you go Dual HDMI, or one VGA and
one HDMI. Or do you get Dual HDMI and an HDMI->VGA adaptor.
One slot or two? Fanless or big honking fan? If you're not playing
games, getting a video card which will have good opensource support is
my metric. Go AMD.
Also, quiet is nice.
Tim> 4. Harddrives: If your going to spring for 1, go ahead and buy
Tim> two and then mirror them. Mirrored drives have now saved my ass
Tim> on three occasions.
Hear hear! It's almost tempting to get an USB thumbdrive to boot
from, and the two disks are just a mirror MD RAID setup, with LVM on
top.
Around $100/per drive is a sweet spot, you can get two 1Tb drives
mirrored. Nice.
Tim> 5. Case: Honestly I like cases that don't resemble a disco under
Tim> my desk. I'm also fond of 120mm case fans. They move a shit
Tim> load of air and are quiet.
I've gotten and been really happy with the CoolerMaster Centurion 5
all black case without any windows. Lots of bays, nice clean design,
plenty of IO ports up front to use with USB/Firewire.
Tim> Power Supply: I wouldn't go smaller than a 350W. If you ever
Tim> decide to suddenly add two more drives or a burner, nothing sucks
Tim> more than your power supply being the weak link.
Go with a quiet and energy efficient one if you can.
Tim> 6. OS: Do it yourself. I'm not sure if Ubuntu will let you
Tim> mirror drives at install, I know the Red Hat family of distros
Tim> will. Doing your own install will at least give you an explicit
Tim> understanding of what packages you've installed. Heck we could
Tim> probably make a meeting out of helping you install and tweak your
Tim> machine!
Absolutely. Have fun with the system.

Re: [Wlug] upgrading suse 7.2 to 8.1
by Gregory Avedissian
Doug,
Thanks for the info and the link. As it turns out, the personal version
is missing about 120 packages out of what I have installed. I recognized
about 30 of them, and the download time is prohibitive. I need to get
the pro version on cd.
Meanwhile, I really wanted to know if XFree 4.x would work with my card,
so I took a spare hard drive and installed debian woody. I installed
xfree 4.1 and had to add the 3DLabs driver from xf3.3.6. Apparentlly,
there's software to make driver work with the new version, and it works
well. I no longer get little squares and dashes instead of letters on
some programs. Makes it much easier to figure out which buttons to click
when you can read the words.
I'd tried debian a couple months ago and was unhappy with the
installation process. Someone on this list suggested installing just the
base system and then using apt-get to install the other packages I
wanted. That seems to work out very well with almost everything (not ALSA).
The other reason I wanted to upgrade was to be able to run a newer
version of mozilla with junk mail controls. I'm using 1.4, and the junk
filters work pretty well. In fact, they work so well that I haven't
wanted to boot suse to get my mail. That's part of the reason it's taken
me so long to get back to you on this.
Thanks again,
Greg

Re: [Wlug] Need some help with digital signal processing ...
by Randall Mason
The long and short of this is that you need to figure out what the sound
looks like. Is it a simple sound that's easy to differentiate by just
choosing the highest peak on an FFT? If your doorbell has a peak at 10khz
and your dryer has a peak at 5khz, it should be pretty easy to do if 4.9khz
< max(fft(audiodata)) < 5.1khz then dryer; if 9.9khz < max(fft(audiodata))
< 10.1khz then doorbell.
Most likely it's not going to be that easy. Also there is the possibility
that the dryer manufacturer and the doorbell manufacturer used the same
component for the buzzer and it's going to be mathematically the same sound
pattern, but differ on harmonics blocked by the room.
You could need to use the whole fft of the sound, recorded at many
different locations in the house and then use nearest neighbor for the
convolution of the "new" sound with the old sound and then compared to a
database of previous sounds. You would need a large database of example
sounds to compare with. Probably at least 100 examples of each sound that
would go off and then you would need to set a threshold of "closeness" so
that you don't always detect new sounds as one of the old sounds.
If this didn't work, then you may have to go with a hefty fingerprint like
chromaprint or echoprint. Those would give you so much info about not just
the frequencies, but also the rhythm of the sounds. Like maybe your dryer
and your oven have the same frequency pattern because the manufacturers
used the same buzzer, but they pulse them differently. That's one
advantage to these full fingerprint libraries. And somebody else did the
science, so you don't need to write a dissertation in DSP to be sure that
you have some rigour to your approach.
Chromaprint <http://acoustid.org/chromaprint> would be a good library to go
with in that case. It's part of the acoustid project and has a great how
it works <http://oxygene.sk/2011/01/how-does-chromaprint-work/> blog post
for the acoustically curious. The problem would be that it's mainly
developed for sounds as complex as music, so I don't know how it would work
with a "buzz" noise. It's small enough and fast enough that it can happen
quickly enough on a phone. That's how programs like
shazam<http://www.shazam.com/>work. They make the fingerprint on the
phone from a 10 second recording
and push it to a server that processes it. Shazam has riddled the
landscape with software patents, so chromaprint isn't a replacement for
that, it's just close enough that it may work.
Other things to look at:
http://code.google.com/p/musicg/ - A java audio DSP library. Does
fingerprinting and stuff.
Echoprint has been ported to Android:
https://github.com/gvsumasl/EchoprintForAndroid
If you send me some example sounds, I can look at them in python or
something and let you know what I think about different metrics that you
could use to compare the sounds. Specifically a recording in a loss-less
codec like flac or without compression like wav would be important because
MP3 and such destroy parts of the audio waveform. 'Course I could just
record my kitchen timer and let you know what it looks like...
Your offer to do the programming is great, because I'm no app dev, but I do
have some education and experience with signal processing.
