Not a chance this time of night. ;)
back in a bit.
todays task is trying to figure out how to build a powder coat booth for $ trivial
probably using an old office fan and some washing up liquid bottles
a pair of Val's old knickers, a toilet roll, and some sticky backed plastic.
thats the sort of thing ...
but without the smell of fish, if possible
there went one of me ...
I'm trying to find some suitable filters, cheap
pleated paper I guess fo rthe final filter
I was wondering about just stacking a few dozen of the cheapest car air filters I can find :)
Truck air filters
I figured they;d be in the several undred pound category, no?
Or what about a sheet of the foam they use for 80mm fans
foam I fgured would be too leaky
I thought pleated paper, or maybe fine weave cloth
I have a desire NOT to fill the factory with powder coat!!
you think truck air filters might be cheap though??
Might be worth a look
It really depends on the volume of air you need to filter...
An electrostatic filter might be better.
Burn No. 5 on the go.
I've got 208 fragments in lost and found on the suse box. Think I need to start over?
'pends where the fragments came from, and more importantly, How.
There are only a dozen or so files in /etc now.
That doesn't sound good
robin: still there?
guess not...pity...could tell him about GEMA powder booths
nothing special...pressurize a little room...pleated paper filters...keep a shop vac around
good morning paul !!!
I just had a great idea last night
you'll probably say it's a bunch of bull.. ;)
but I'll tell you anyhow
how about this: what if hal modules are smaller things
e.g. for STG not a driver for the whole board
but instead drivers for the components
hal_ls7166 , hal_82c55, etc
and those can be used for many hardware parts
just need a base_address for those, and maybe a few more things
Base address, byte boundaries, IO or memory mapped....
too complicated ?
Some things are best done in C
I thought maybe there's a way to have a stg.hal
well... on the other hand it's not possible to load a module more than once
so it's pretty complicated to do the param_parsing inside the module (CFG="200 201 202 203")
Pass smple numbers NOT text that requires parsing in kernel space.
manipulating strings in kernel space is all wrong
I know.. I don't like the cfg from hal_parport
so why follow the example.
I don't want to...
I was only checking if it could be done with more components opposed to a single driver file
and what that would imply
I 'spose taking it to it's logical conclusion, turn every function within EMC in to a HAL module...
well.. not that extreme
but I agree that keeping stuff in c has it's advantagies
if it's GPL it can be used in other drivers too...
Licensing is secondary to the efficient use of code.
Another thing to bear in mind...
gcc can do a far better job of linking and optimising code than most of us.
how do you mean this?
Write a series of functions that use small (2-3 line) function calls...
bung in some large loops and switch statements
gcc will inline many of the small functions, unroll loops, and skip any unreachable code
Depending on the level of optimisation called for.
Splitting the short functions off into a separate module "just because we can"
and you loose any chance of opimisation.
but, hey, a modern processor can do a jump in less than a nano-second...
Arg... Don't have my Intel book to hand, so can't give a timing for a typical test&branch instruction..
paul_c: they barely publish info like that anymore, it seems like.
paul_c: but with many-stage pipelines, a mispredicted branch might take tens of cycles, or >5ns on a 2GHz machine.
The size of the cache(s), pipelines, speed of main memory...
yeah.. it's all into non-RT direction nowadays
03Zathras 07BDI build system * 10Babylon Cluster/comps.xml: File changed. New revision:picax.xml
hi, I'm here
* alex_joni is reading about AXIS
uh oh, somebody found our website
so what do you think?
but I'm not gonna say anything :D
I think .. WTF is it hidden?
it should be out there...
I abandoned the SuSE after two crashes.
have you been following the USB stuff?
the USB-parport adapter discussion on the users list
The second ate most of /etc and tossed 200+ fragments into lost+found.
At a glance only.
What are you thinking about USB?
huh... never had a single crash with SuSE
well.. I think USB is pretty useless for RT stuff
but then I found this: http://www.low-cost-cnc.com/ll_cncarchitecture_big_cnc.html
Yes. At least the way folk are thinking about it.
rayh: Will check on the missing dep.
ray, paul: is there a need for a iso's-mirror?
Not yet - Still at the beta stage.
I meant generally
also for the BDI2.x and BDI-TNG & Live
TNG is unsupported and needs to be retired
ok.. then let me know when the need is there (I got the bandwidth & the disk space covered)
Sounds good to me. That way we have an (almost euro) mirror.
When does ro expect to join?
Looking at slimming Live down so that it will run on a minimal system without many of the desktop apps
That's not so far off.
* alex_joni left ...
Found the problem with the kernel not installing...
What was it missing?
It was a case of what wasn't missing....
I had a whitespace in the XML tag
Oh. That's much worse.
are you sure that missing dep was libneon and not libneon24 ?
Might have been. It went by pretty fast.
hehehe.... Looking at the cia stats....
Zathras is No. 1
alex_joni is 2nd
* paul_c posts to emc-user commenting about the use of legacy units (the Inch).
I found Tom Hubin's remarks a little bit offensive, since I'm sure patches that fix metric behavior would be addressed, and someone committed to working on metric would be accepted as a developer.
(says the guy who's never committed anything to EMC yet)
er, "patches .. would be incorporated"
Priorities - I do the BDI, other things are lower down the list.
cradek: since you just looked at emctaskmain.cc, will you fix the interp_state-when-starting-by-step bug?
paul_c: and we thank you for doing BDI!
so this is just a problem with the tcl backplot?
I think so.
unsurprisingly, gplot and emcplot3d both get this right...
at least they display a square when I do this
try it with G20, then again with G21
you mean g20 before the first g1x1?
huh, mini draws a square too
what am I missing here?
I agree with his comments about G92
if you can't use fixed tool offsets, you're screwed
the image should be scaled by 25.4...
I've never used the tcl backplot, so maybe I don't know how it works
Agreed the G92 needs looking at...
I have some files that claim to fix it, but
I bet you *could* do it using run-from-line
it sucks but you could do it
I have some modified files, but it is a bloody nightmare trying to pick out what changes have been made to the actual code
if/when I can sort out the mess, I'll try to commit some of it.
cradek: If you are using a current mini gui, the g20 and g21 have been fixed in the plotter.
rayh: ok, that explains why it worked for me
I'm not certain how close the two squares will come to overlapping.
I changed to metric for one corner, so there is only one square
it looks fine
do you know if Tom has a sherline?
Okay. You could test it by making a 1 inch square followed by a 25.4 mm square.
I believe so.
I could rustle around and try to find my list of S customers.
what's this g92 stuff again?
nah, don't bother
ray, you proved that it works proprly
I use it a lot
As long as you stay within the NIST parameters it's okay.
the only thing that was problematic was the gui sometimes not displaying an offset
so I just always start with a g92.1
Yes. I found that it was a bit more than just the gui.
oh I see
So did one of my customers who drilled a hole in his work vice.
message was not reported?
Now I can't remember just where the issue was.
oh well...just took delivery of over $2000 worth of prime cherry
emc will turn 75% of it into sawdust.
I feel a bit like the old beer commercial announcer. "I've been drinking xx ale for as long as I can remember -- which is about three days.
well late lunch break for me...later...and I have a bad case of CRS as well!
Looks like our bug and feature tracker has a bit of a issue with forwarding to the dev list.
yup - Thought I had fixed it...
I'm trying to use supermount like live. Modprobe supermount. Anything else.
/cdrom /cdrom supermount auto,users,ro,fs=auto,dev=/dev/hdc 0 0
and add supermount to the lis in /etc/modules
I've got /media/cdrom.
/cdrom /media/cdrom supermount auto,users,ro,fs=auto,dev=/dev/hdc 0 0
Hmmm... that doesn't look right...
Is the drive hdb or hdc ?
made a link scd0 ->cdrom
or should i use hdc?
burner it is.
Is ide-cd being loaded along with scsi-ide ?
cdrom /media/cdrom supermount auto,users,ro,fs=auto,dev=/dev/sr0 0 0
or) cdrom /media/cdrom supermount auto,users,ro,fs=auto,dev=/dev/scd0 0 0
I don't see either ide-cd or scsi-ide but scd0 will work with a manual mount.
must have compiled them into the kernel then..
I'm not getting either floppy or cdrom with any of the lines.
supermount loaded ?
2.4.27 kernel ?
do a "mount -a"
none already mounted or /dev/pts busy
according to mtab, devpts is already mounted on /dev/pts
fs type sysfs not supported by kernel
get the same warnings here...
mount should tell you if the CD is now accessable.
I could mount before supermount but with the mount command.
does "mount /media/cdrom" throw any errors ?
running it as root ?
Ah. A reboot with fstab in place and supermount in the /etc/modules got it going.
a bit drastic
Yes it was.
I will not allow me to unmount manually now.
Once supermount is running, it looks after mounting/unmounting
although.... "umount /media/cdrom" should still work...
Okay. If I remove the media and look then install media it works properly.
The supermount works much better if there is a directory above the mount directory.
When you hit that directory with the browser it looks at the cd or floppy.
Can you try something for me....
pop the BDI-3 cd in, and run (as root)...
apt-cdrom -d /media/cdrom
apt-cdrom -d /media/cdrom add
need to mount it first?
Got the apt-cdrom help message. Want an add
try the second incantation.
* paul_c forgot the add
Okay it did something/asking if I want to repeat for other cds
there isn't any more...
Now try "apt-get install emc"
* asdfqwega just bumped 2 20Gig HD's off the desk and onto the (concrete) floor
It should ask for the CD
emc is already the newest version
hope they didn't have anything important ont hem
Darn. need to get a net going.
OK... now "apt-get install synaptic"
not available, referred to by another package.
package synaptic has no installation candidate.\
That cd access broke supermount. Had to mount /media/cdrom
better make sure I get that right on the next CD...
* paul_c wondered if apt-cdrom would unmount the CD
Yes it did.
Or said it did.
Need to try playing around with autofs and see if that causes any problems.
can I write a micro-HOWTO a bit later ?
asdfqwega: hope you don't care too much about whatever data was on them
(flog them on ebay)
jepler: the first junk power supply I picked up said 12V/10A
paul_c: is it possible to "apt-get" on bdi live rc46 without doing a hard-drive install?
jepler: no kidding
jepler: Yes, but it soaks up memory.
Who's needing power supplies?
but my "cheapest CNC retrofit kit" just got a lot more expensive if I ship an AT power supply with it.
I see there is a CVS directory with your info on it in the cdrom.
paul_c: how? I get an error about free disk space on /var/apt/something
You need loads more memory then..
paul_c: It's a 1-gig RAM machine
rayh: I know about the CVS dir...
Need memory: Just steal a few sticks out of your (gran)kids hot-rod gaming box
Can't you make a ramdisk on the hd and use that for rc46?
jepler: I suspect translucency might be causing problems - It is something that has come up on the Morphix list
Yeah, I *think* that apt is just looking at "df" which says there are 0 blocks free on that partition
I mounted an ext3 partition on the hard drive and told yum to use that for temporary files, but then I got some error about cross-device hard links (my bug reporting stinks, I didn't write anything down)
You could try overlaying the hd on top of / with translucency.
(might get a bit messy in places...)
can you tell me a little more or point me at a document about this?
gimme a sec...
[20:40:55] <paul_c> http://sourceforge.net/projects/translucency
time to throw some food in the oven
thanks for the link
Cooo... A Mike
so is tbl going to sit there all night lurking ??
running another test install...
are we having fun yet?
I'm having a great time
I'm having as much fun as a SM dentist
