the funding continues to flow SWP
oh is this just some scam to keep SWPadnos in caviar and champagne?
heck I wish I'd known that
heh - I wish ;)
I even spent the extra $10 for a swap meet table
I can't go...to much work...pity I was just by there a few wees ago
a few wees
03swpadnos 07HEAD * 10emc2/tcl/bin/emccalib.tcl: Fix handling of new and old widget values when morethan one HAL parameter is set from the same INI variable
you mean "wii", right?
I swear I hit the k key
wii 360 extreeeem
still beta testing my friend's bad keyboards
(the military gaming station)
eeew - some of those images of tkemc (in the user manual) need significant quality improvements
SWPadnos: are you looking at the pdfs, or inside lyx, or what?
SWPadnos: are you looking at the pdfs, or inside lyx, or what?
SWPadnos_ is now known as SWPadnos
the one that was put on linuxcnc.org
page 17, in particular
that's one of the ones I changed to be 85% of the width of the page
before it stuck a few inches off the side of the paper
however, I'm still a bit surprised at the result
it's highly compressed somewhere in the process
if only I could figure out how to look at the original on a BDI 4.30 install
firefox will probably load it
ok. the original isn't that good either. GIGO
the postscript document produced by 'dvips' has the same problem
but it looks ok in 'xdvi'
the source image looks fairly crappy
not that crappy
Just walked in, someone having issues with a PDF?
or PS ?
crappy images in the emc2 users guide
there's a perliminary version at: http://www.linuxcnc.org/EMC2_User_Manual.pdf
the images started out kinda crappy, so it's no surprise they look bad in the pdf
whats the source of the original images?
the images are in the documents module at cvs.linuxcnc.org
Hmmm, no resolution in the originals either
yeah - they seemed kind of yucky to me
I just dumped ALL the iamges... not looking too good.
the eps ones are fine =) (obviously)
vector is so much better that way
les_w Um, hurnia test?
just walked in to the office for a bit.
I was watching modern marvels in the music room but got bored.
I still have post quarterly meeting anxiety trauma.
I was thinking about watching a couple of selections from Yanni: Live at the Acropoils
yanni got busted or something didn't he?
I don't know
too much hair, I guess
I think so
saw mug shots on cnn
family violence or something
yep - "domestic battery"
i'm not working tommorrow
need a break
whatever will you do with al lthat time? ;)
have that 5 ton pile of manure with my name on it
front end loader!
tractor seat time
uh - have fun
I can take 500 lb bites with the bucket
good stuff really..."garden gold"
for some reason "5 tons of manure" doesn't sound that good to me
maybe it's because I used to take the school bus past a lot of farms that used nice fermented liquid manure every spring
all those years in school and what am I doing tommorrow?
shoveling shit, as it were
diesel fuel is getting really expensive I notice
worse than gas
military == diesel
well if things ever get really badI can just grow it
fatweed is about 20% fatty acid esters by weight
remove the glycerine....biodeisel!!
they are triglyceride esters.
so...that big pile of manure can be a big tank of gas...If I need it to be
of course $3/gallon gas or diesel is still relatively cheap. May not stay that way though
it's half of the cost in England (and most of Europe as well, I think)
and it was that expensive a couple of years ago, when I was last there
yeah people can survive $6/galgas
at about $10 or so things would get significant
our basic suburb commute/ poor mass transit (compered to europe) would have to change
well, since the only way to get people in this country to conserve resources is to make them unaffordable, I think $10/gallon gas would be a great benefit to the wrold ;)
as sure as a loaf of bread will cost $20
Better not... I get bad gas mileage as it is.
unfortunatrely, it'll probably happen just before we run out completely
ie, too late to matter much
we Americans tend to be too short sighted for our own good
aw, above a certain price ethanol and coal derivatives will kick in
prob at the $10 level or around that
SWPadnos: I can't even fit into a majority of todays' cars. Not without removeing the front seat that is.
heh - it's Police Academy all over again ;)
ethanol can be a joke if one considers thar petrochemical fertilizers are needed for production
politicians lioke to tout it
yeah - the net energy is negative in a lot of scenarios
What about this corn stuff? Or is that ethanol?
and soy, I think
We got lots of soy, that's for sure.
I think we have more soy than any other crop
at least soy fixes nitrogen
corn is nitrogen hungry
fixing carbon will be the big problem
diamonds from air - that would be a great business plan
I've thought about making petrochemicals from air (using solar energy for the endothermic reactions), but I'm not sure there's a reaction sequence that can do that
Im going for the magic 25:1 carbon to nitrogen ratio here
hmm petrochemicals from air.....
all the components are there, I think. it's a matter of putting them back together
maybe nanotech will be helpful someday
well, I am innoculating legumes to fix nitrogen better
but I get only about 200 lb nitrogen/acre year
better than nothing I guess
if 1% of the population did that, we'd be a lot better off, I bet
68 octane though
we can deal with that though
it's funny. I was reading about jet fuel a bit last week
it's not so explosive as people think - it's more like kerosene
but very light (62.5% the density of water)
it pretty much is kerosene
yeah - it's the energy density they're going for
there was a contest on the flight to Las Vegas to guess the takeoff weight of the plane
I won two tickets to see Blue Man Group
well I use 6 lbs/gal when doing weight and balance in piston aircraft
I don't get to fly jets
I had mis-estimated the weights of the plane, the passengers, and the fuel, but I was only off by ~750 pounds with the total ;)
blue man group...from chicago...cool
out of 157000 pounds or so
yep, in Las Vegas
haven't been yet - need to get tickets when I'm actually in town for more than 24 hours
the planes I fly have about a 10 inch range for cg....have to do some first moment calculations if you have a lot of fuel or are carriying lard asses in the back or both
I've seen that on the smaller passenger jets as well (50 seats or less)
they often ask a few people to move from the front of the plane to the rear
well cg too forward and things get too stable
hard to control pitch
cg too far back and stalls can be unrecoverable
and that's no fun
but you can't spin without stalling
I think current training is a bit off...In my spin training half fuel and no back set pax were required to rech utility category where spins are approved
but the aircraft would not stay in a spin
If you had back seat guys and wake turbulence caused a spin
I would be totally unprepared.
to be fair, the FAA says just don't do spin training
I requested it
I just refused to drive around in airplanes ithout ever having been in a spin
I'm pretty sure my wife did spins / stalls in the limited flight training she took
it is required in canada
here we do stalls, but not spins
as I said most trainers wi8ll not spin in utility category anyway
ok. I could be misremmebering (she did the flight training a couple of years before we met)
but lard asses in back....wake turbulence....and they will spin real good.
and we nevert get to experience that
good to note ;)
that's why I don't buy the chocolate covered donuts too often ;)
they're too hard to resist eating
actually in utility an attempted spin turns into a dangerous spiral dive quickly.
My instructor said"count to 5 and you're dead"
if you do nothing
that could be a bummer of a situation
well you get to vne and you could have stuctural failure
velocity never exceed
basically, the wings MIGHT stay on
well, the *never* in there is a good clue
yeah. In the planes I fly that speed is usually in the 200 mph range or so.
sometimes more, sometimes less
ah - considerably slower than the ~200 MPH takeoff speed of the commercial jets ;)
jet airliners have vne of about 300 knots thogh
a little more
so how can they go 600 mph?
only at high altitude
right - that's at stp
indicated airspeed is under 300
cause the air is thin up there
the aairspeed is still high, but the pressure is lower than at ground level
oh well, I have the ratings, but not the money to fly jets
only single engine
I only have the money to fly jets in coach ;)
at least I have the status to get the extra legroom seats in the front
oh I don't get to do that
bulkhead sets...lucky you
exit row - even better
I can hsrdly reach my stuff under the next seat
and I have long arms
but you have to agree to assist flight crew....
in exit rows
yeah - I'm a young strapping male
I can't make that claim...but I will move a few tons of cow poop tommorow
thanks to Mr. Otto diesel
and Mr. <whoever invented the hydraulic cylinder>
go Otto H!
or was that Titsler
actually some roman I think
cut it out...I don't want to think about my second wife....

if i've got a complex schematic design with a lots of ttl gates, is there no way whatsoever to have some kind of automation for the component placement?
not in a free PCB program ;)
it's not even that good in my $12000 package
so that feature must be very complicated to develop
there is a nice feature that will automatically do pin/gate swapping to improve routing
but that's in Altium, not Eagle
is Altium a $12000 software?
I have a (manual) machining question: Whats the best wat to bore a flat-bottomed hole, if it's bigger than any drill or endmill bits that I have? I've been doing it on the lathe, but it takes forever.
you can get the PCB and schematic software for $10k
add in the FPGA stuff, and it's $12k
get a boring head
SWPadnos: that's boring
I have one.. just drill it as big as I can and bore it the rest of the way?
I know, but I'm a geek - what can I say?
yep. I think that's the best way
I spent an entire evening making one bearing-mount, it sucked.
it should give you the closest to a circular hole you can get on a manual machine
I'm so slow..
they're pretty precise hunks of metal. if it works, you did well ;)
it worked, but it took like 4 hours.
[15:42:23] <bill203> http://photos.xmission.com/bill/v/machining/IMG_0284.JPG.html
my mill project is starting to look like something...
most cadding program seem to pretty primitive. no automation whatsoever.
I wouldn't try that on anything but a lathe...
what sort of bit would you use to do it on a lathe?
I might use the cnc mill to cut it out in a helix first to get it close
the cnc mill is a manual mill ;)
yeah I know, that sure makes it harder
a rotary table is helpful for hogging it out
bill203: I would scratch my head over it for a bit: does the corner have to be square?
then a boring bar or lathe for the final passes
I used something like this: http://www.thetoolgarage.com/images/aw2k/LotImg290.jpg
cradek, square enough for a bearing to seat.
bill203: a triangular insert tool could cut both the face and the shoulder
the hole was too small for my insert-holder to get in there. :-(
I just have the regualr ebay-cheapie TCMT set.
all boring is a pain
I was thinking an endmill and a rotary table would rough it out pretty quick, then finish on the lathe.
another reason to get a rotary table, I guess.
that sounds like a great idea
oh you don't have one... not so great an idea then :-)
you could cut a nice helix approximation for roughing if you had one
save myself 2 hours.
does your lathe have a back gear? Could you just go get the drill you need?
you could drill an awfully big hole with some lube and back gear
it's a chinese 7*10..
the extra gear that makes the spindle turn very slowly for threading
oh, uhm, it goes down to a few hundred rpm, but not slow enough to watch it turn.
so I'm gonna say: no.
but since i wanna do the component placement on this http://www.carmi.se/misterstarshine/Design/L297_sub.brd
what should i look for in DC++?
yeah you can't drill very big with that
(not without some violent things happening)
'cause there is no way i can with my low skills make anything decent from that
you can see it here, actually: http://scoot.net/garage/
the cameras light-level jumps around a lot, sometimes you have to reload to get a good picture.
looks familiar but mine's not so neat
heh, they get worse?!
i guess you guys do boards sometimes?
all component placement and optimization by eye!?
Bo^Dick: that's the best way
but you need to make quite a few before you start to get it right (at least a dozen)
I'm dealing with professional cadders here
the "easiest" thing might be to generate postscript of your data
I'd say that .brd has a lot more components than on a typical project of mine
brd is eagle right?
ok cant see em ;)
I don't think you'll fit all that stuff on the 100x80mm board size allowed by the freeware version
i've got some simple questions about eagle. is it possible to select a group of parts and make a new document containing a copy of that group? is it possible to show/hide the ratsnest selectively for particular nets?
do you have the real eagle, or the free "light" version?
I guess it must be real, or you wouldn't have been able to place parts where they were on that board
i've got the real version
wow the full version is not a small investment
yes. that's part of why I just dove in and got Altium
$1200 .. wow
no, I mean for Eagle
Bo^Dick: I'm just surprised you bought it, since you don't part with money easily when it comes to parts
I'm off today
yeah, i'm surprised too
done with the shit shoveling?
lost a chicken. She was setting. Eggs about ready to hatch to. damn
err - Manure Moving
no, shoveled more today
about a ton I guess
it's a disappointment no advanced script files are available for eagle :(
chicken got stuck in the tiller eh
not sure. It wasn't a dog...the nest was too protected. Some other critter....hawk or opossum or something
I have seen lots of hawks around
vulpes vulpes batman!
i'll get some chicks to replace them
they are free range, so I expect to loose some
we are kinda in the city and have lots of predators around too
so the chickens havent been outside yet this year.. :/
you have some huh?
Im from the city too....new to this
the chickens are someone else's project, i just watch curiously
except when defending a nest, they can usually get away from predators pretty well
in my back yard i have seen: owls, eagles, hawks, possums, dogs, a pair of coyotes, a fox..
too bad...that was the chicken that pecked the crap out of Paul Corner
He was sitting on the porch reading a math book....chicken wanted food and walked up....then pecked him when he had no food!
I laughed and laughed
then the year before there was the famous episode where my ex wife forced him to eat grits
He just hated them
looked like he had a mouthfull of shit according to her
you'd think even grits would taste good to a brit - I have heard bad things about their food.
but she was cute, so he ate the grits.
Chris when I go to the UK I have the urge to take groceries
i've got a design with 15 DIL14 packages and it is very messy. is it because i've placed the components in a poor way?
you need protel!
Bo^Dick: does the full version come with some kind of support? I think mine (nonprofit version) didn't
I got a seat from the tool works. Almost a crime since I almost never use it
I use the spice sometimes
spice is good :)
* alex_joni loves spices
cradek: is an encoder on a lathe with 100 holes/rev too coarse for a good thread cut?
03alex_joni 07HEAD * 10documents/lyx/emc2/installing.lyx: the pdf created had problems wrapping the line
03alex_joni 07HEAD * 10documents/lyx/emc2/Master_User.lyx: paragraph justify for all the included files
exactly what does the "backwards annotation" feature do?
Lerneaen_Hydra: does that give you 400 or 100 transitions per revolution? 400 is great, 100 is maybe a bit low
100 holes usually gives 400 transitions
cradek: there are 100 holes, so that would make a sqaure wave that has 100 repeats/turn, so 400 transitions
cradek: how many holes does yours have?
cradek: I've managed to get ahold of two EMCO compact 5's
Lerneaen_Hydra: the one on my mill has 400 transitions per revolution, the one on the borrowed lathe has 4096
is there any noticable difference between 400 and 4096?
you should do the math for your setup: consider that you want less than one transition per base period, consider your axis speed, consider what thread pitch you will want, and calculate the number of counts that's optimal
probably only limiting the speed on high rpm (as the parport can't keep up)
but it's better (4096) on low spins
say you have a base period of 20us, your axis can move 20ipm, you want to cut at least 10tpi, you can calculate the best spindle rpm and then from that the appropriate encoder resolution
yes more is better but it greatly limits the spindle rpm if you're counting in software
I think the lathe tops out theoretically at about 360 rpm so I run it at 250
(not sure about those numbers)
isn't that very low?
the ones I've got go to 3200rpm
you can't thread at that speed - your axis would have to move 160ipm to cut 20tpi
my axes can move at 700mm/min
and my base period is currently 20µs
if you're going to be using software counting, be sure to figure all your numbers carefully before you order an expensive encoder!
I already have the encoder
it came with the lathes
which I got for cheap (free) :D
ok, free is a nice price, I don't have much experience with that
as always, donations happily accepted
which is the same thing I told the people that gave them away ;)
who wouldn't? :)
the weight makes shipping prohibitive though, they weigh something like 70kg each and are very bulky
you'll have to send them some beer/pizza/pie
I bought them some cake
hopefully I'll be able to gut the controlling system and use the stepper drivers and get EMC to control them
sounds like a fun project
too bad you can't come to fest in a couple weeks, you could convert them there
the fest is in the US I guess?
heh, that's a bit far for me
we swede's will have to get our own one going ;)
the people that gave them to me seemed very surprized that I was going to "make my own" controller system
something like that seems to be out of the scope for most CNC people it seems
it's true machinists don't necessarily know electronics or software
cradek: true the other way around too..
give a software guy a lathe and let him make a bolt
I guess software/(machine)-hardware people are rather unusual
* cradek waves his arms
* alex_joni is busy on the floor
* Lerneaen_Hydra is still completly concentrating on the lathes
cradek: alex_joni lies... I see him getting a beer fro the fridge!
alex_joni: If it wasn't you, then wipe the beer mustache off your face!
I just shaved it off this morning
alex_joni: Uh Huh, your lucky you dont get a MUI!
[19:50:52] <Lerneaen_Hydra> http://img343.imageshack.us/my.php?image=lathe1ue.jpg
alex_joni: MUI Maching while Under the Influence!
mail user interface?
Lerneaen_Hydra: no tailstocks?
programming stuff in the lathe is a real PITA
yes there is one but I removed it for the moment
I'm not used to the english terms
a small one made from zinc
like alex, your english is so good I forget
or well, the base is
the travel is only 35mm though
cradek: I'll soon talk magyar with ya all
travel of what?
oh the tailstock
that's probably typical for such a small machine
sherline's is about like that I think
there was both a... uh... pointy-stick-that-you-push-into-a-pre-drilled-hole-that-has-a-bevel-thingy (*dubb*docka) and a chuck for drills
it's scary how you have to reach over the work to estop - seems like that should be in front
heh, yes that is rather inconvenient
ah the pointy stick is a "center"
"live center" has bearings, "dead center" is just a point that you oil
what's also rather inconvenient is that pressing estop wipes the memory as it only is ram :(
the chuck is ... a chuck
it's a live center then
oh haha that's terrible
no SRAM ?
so you have to reload the program from tape
I mean battery backed up
take about 90 seconds
it has a small digital tape casette
paper tape or magnetic tape?
that's a LITTLE less of a pain
similar to an automatic answering machine
seems like you should use emc doesn't it
indeed it does :)
however making the program in the first place is the real program
the only way to see what you're doing is a 6-char numeric display a 6 LED-s
and the numpad
cradek: I don't know if it's scarry or a good thing that you actually needed to ask... Paper or Plastic =)
yes, I really really want EMC on it ;)
it looks like it will make a great conversion
the thing is from 1981 though
fortunately everthing inside has its own dedicated PCB, so I save the PSU, motor driver, and stepper drivers
I wonder if it can even do coordinated moves (or arcs)
arcs is doable
coordinated movies up to 1:39
cradek is there any way to transfer paper if that was the case?
minimum step of 1.3-something /100 mm
(by 1:39 I mean a cone with a ratio of 1:39)
Jymmm: sure, I've done some of that, you just need a tape reader with a serial port
is the output paper with holes? or maybe ink?
cradek: Oh, well that make it much easier, thought it might have been some funky encoding method
Jymmm: no, just 7 or 8 holes across the tape
Jymmm: so you could read it by hand if you didn't have a reader
oh, ascii ?
8 holes wide by however many byts the app is?
sounds very archivable
a gcode program would surely have been 7 bit ascii
ah, someone was thinking that day
at least moreso than a CD-R
the valume is a bit greater though;)
yeah it would be good for archiving, especially the mylar tape, but the density is extremely low
cradek so the reader is just some opto thingy?
* Lerneaen_Hydra really hopes the reader isn't mechanical
some were even mechanical I think
Jymmm: used to be mechanic
both mine are optical
one is high speed and can read tape at 1200 baud. Do NOT get in the way of it!
lol... I bet
hell, irc is like 300 baud
1200baud? that's fast, what is the distance between the holes?
I can't remember if the punch is 110 or 300 baud, it might be able to do both
[20:04:37] <jepler> http://www.pdp8.net/pc04/pc04.shtml
Lerneaen_Hydra: 1/8 or .1 inch maybe? not sure
that's still very many inches/sec of paper that goes through it
remember that's 1200 bits, not bytes
but yeah, it's fast
baud doesn't say anything about bits :)
so 1200/8 -> 150 bytes/sec
communications is always in bits, not bytes
that's still respectable
Jymmm: I tend to disagree
even by todays standards (for text and the like)
at least on more modern modems a baud is 2-4 bits
more than enough for CNC
alex_joni You can disagree, but what about a modem... it's 56K bits, not bytes
Jymmm: yes but more than one bit is sent at a time so it's lower than 56kbaud; alex_joni is technically right
that's why they changed to saying 'kbps' for modems: baud = bit stopped being true
guess we're both right
Jymmm: phone lines allow something like 14 kbaud
baud = symbols per second
[20:09:48] <jepler> http://en.wikipedia.org/wiki/Baud
and that stays fixed (baud = changes / second)
"Thus, a 2400 bit/s modem actually transmits at 600 baud (600 symbols/sec), where each quadrature amplitude modulation symbol carries four bits of information"
(despite being universally called a "2400 baud modem")
I wouldn't have chosen symbol as a name, but that's it
nothing since 300 baud modems transferred only one bit at a time
on very old modems (no fancy encoding), you even had it the other way around
one baud = less than one bit
that I've never heard of
because you had to transmit parity & all that
so to transmit 8 bits, you had at least 9 bauds
start, stop & parity bits
but that was before 'advanced' modulation schemes
like phase modulation & frequency modulation
that's certainly never how I thought about it
seems some did think like that about it.. (I remember reading it like that way back)
Alright... what's the OLDEST storage technology you've used (not hobby)? cassette and 8" Floppy here.
depends how zou rule hobby out
yeah the spec is ambiguous :-)
depends how you rule hobby out
Since cradek is building an Altar, it doens't count =)
I only started working a few years ago...
<smart alek response> my brain's memory (in use since 1 billion - 500 million years ago)
so that probably means I didn't even use 3.5 floppies for work
(not my brain as such, just the format)
I used cassette for a long time on my "real" computer at the time, don't know if you count that or not
alex_joni not necessarily c/NC
no, I mean WORK
then lots of different floppy based machines
I had a few myself, but at home
yeah at home
or in school
memory cartridges for the Exidy Sorcerer computer
I've also used computers with no mass storage whatsoever, but for fun, not for any purpose except learning
I remember playing my first game on 8" floppies (at my dad's working place)
cradek: no mass storage? which storage did it have? only rom+ram?
cradek: star wars (text mode)
Lerneaen_Hydra: I think just ram for the simplest one (KIM-1)
just a hex keypad for entering your program
* Jymmm misses BBS'es
Trade Wars 2000!!!
I programmed on an Atari 2600. There was a "BASIC" cartridge. IIRC you could write a program up to 63 bytes long.
there was no storage after you turned it off, of course
Heh... Vic-20 had 3.2K ram =)
63 bytes? isn't that like 10-20 rows?
heh, I remember playing a lot on spectrum later (some 8080 system), and it even had a BASIC voice synthesizer
that was very advanced stuff :)
that's almost in the realm of magnetoring storage

Oh man... Berzerk
Breakout 1978... yeow
I think anything that doesn't use removable media is not a backup
wrong window again
who let the newbies in this channel?
cradek: have you ever set up software raid on ubuntu?
dunno.. but they are everywhere
SkunkWorks: I installed on spanned drives once, it was hard
haha programs up to 63 characters in size
cradek: great :) We have 4 9gb drives I would like to setup as raid 5. doing a bunch of research right now. Damn linux users assume some sort of base knowlege of linux.
SkunkWorks: sounds interesting but don't look at me for help
SkunkWorks: THOSE BASTARDS!
u n00b. dont u no n/ething?
cradek: no problem. we will get it - it just might take a few tries :)
ur such a luzer! ;)
"your a looser" haha
I love the contraction of "any" to "n/e" - that always gets me
SWPadnos: it things like - partition all drives your going to use in the array. Make array. done
wish I could spell "a" wrong but I can't figure out how
sounds like a
or the fonzie approach - aaaaaayyyyyyy
mkraid is your friend, unless they changed the name
hey - could be
is what I got out of it so far.
Madam, I'm Adam
[20:42:02] <SkunkWorks> http://www.howtoforge.com/linux_software_raid
one of the links I have been working with/
I was going to ask on #ubuntu but I think I would have vertigo before I was done.
SkunkWorks: Wait a sec.... how are you getting five drives on to a mobo ?
there's two of us now
cradek he never said scsi =)
Jymmm: even IDE+sata gives you 8 HDD's these days
no but he said 5 9-gig drives
yup, 9-gig is a standard SCSI drive
I've got a motherboard that has 6 IDE ports, so 12 drives
8 drives RAID, 4 on the "standard" connectors
mine does 8 IDE, but uncommon
it's almost like that's the only size they ever made (I'm sure that's not true..)
actually said 4 - but there are 8 in the server. 4 are used for a windows 2000 raid
that's normal these days, if you can find PATA motherboards (most have 2-8 SATA + the 2 PATA connectors)
SkunkWorks: Eh, buy two 300gb and mirror the bastards =)
better buy 3 of them, and setup RAID-5
4 for a hot spare
even better :)
but that probably needs a hardware RAID to work properly (I think?)
I don't care for SW RAID for the simple fact if something fubars' it's gonna be a royal pita to recover.
mobo, controller, etc
SWPadnos: I thought it was you that said that linux software raid performs better most of the time than the hardware raid solutions.
ooh...just got a memo indicating the new president of binks and devilbiss spray finishing systems will have a visit
les_w, best to get the rest of the shit out of the way ;)
It might be good or bad
or paint it
les_w or quickly get 9 holes up and going!
she might not go for this way out technology
use lots of fragrance to mask it
SkunkWorks, look at EVMS
[20:50:19] <SWPadnos> http://howtos.linux.com/guides/EVMSUG/
new president is a lady...and I don't know her
oh well I have always been a paint spray gun junkie
the Binks part of the company actually invented the paint spray gun
binks is a good company
I even heard of them :D
if you don't count those cave paintings in the french caves made by blowing charcoal out of the mouth
hmm.. does anyone know how to change desktops on Ubuntu using only the keyboard?
I can't even log out on ubuntu without the mouse
alt-f1 gives you the menu
bill203: nope :(
ahhh, that's what I have set up.
how did you set it up then?
thru the window manager gnone-control-panel, if I remember right.
SWPadnos: thanks = have you used this?
bill203: care to share where that is?
I'm not sitting at my ubuntu machine right now, but I *think* its under the 'system' menu at the upper left.
I see.. the defaults are 'ctrl'+'alt'+'left & right'
hmm... lots of nice shortcuts (had no idea that 'alt'+print takes a screenshot of the current window)
wow - they coppied that from windoze :)
one of these days you'll say they copied Xgl from vista
alt? it's usually CTRL+PRSC
oh, that's consoles, nm
ctrl+prsc - does the whole screen on windows alt+prsc does just active window
maybe try vesa
SkunkWorks : oooooooooh, lemmi try that!!!
fuckin ah alright! that's pretty cool... learn somethng new everyday!!!
Jymmm: your on a windows machine right now?
or maybe :(
Between the KVM, synegry2, and VNC, I'm on everything =)
does synergy work ok?
alex_joni Synergy2 is a network KVM softa thing, not CAD.
[21:23:18] <Jymmm> http://synergy2.sf.net
that works awesome
I know what it is
oh, it's like a super x2vnc
but never got around to install it
It has it's lil quirks, but works great. I love the copy and paste between machines
and I don't have many machines sitting next to each other
does it show display too?
or only mouse/keyb stuff?
alex_joni no, you need multipe CRTs, but only one mouse/kybd for all the machines.
I go between my laptop and desktop primarily
Jymmm: that was my understanding too
not of much use to me..
alex_joni you probably want a network KVM switch then
VNC is ok
and ssh is enough most of the time :)
I use tightvnc all the time for home stuff
I suck at X-stuff, only know my way around the console.. (a bit)
SWPadnos: I tried reading but couldn't figure out the difference?
vnc -vs- tightvnc
Jymmm: that was SkunkWorks not SWPadnos
* Jymmm pokes SkunkWorks
np swampy :)
SWPadnos (just keeping you on your toes)
I'm sitting, I'll have you know
SWPadnos toe exercises =)
he'd make a nice ballerina
one of these days
* Jymmm begins a collections to get SWPadnos a "pretty In Pink" Tutu!
* alex_joni donates from the little money he has
I'm thinking http://www.tutu.com/images/gallery/Pinktutuprg.jpg

ubuntu updates: downloading file 3 of 67
yup, lots of X updates
evening alex ;-L
