[00:16:14] <andypugh> I thought biches were more into moss and leaves.
[00:16:41] <furrywolf> hrmm. not sure I've ever seen a suspension bridge where the cables were solid and part of the catenaries...
[00:17:54] <andypugh> It does seem like an inefficient and difficult way to make a full-size bridge
[00:20:52] <furrywolf> I had fun with the toothpick bridge building contest waaaaaay back when. everyone else was copying standard bridge designs, but I decided they all sucked, since they were meant for an evenly distributed load, not the steel rod placed through the middle of the bridge that ours would be tested with. so I built mine as a triangle instead. :)
[00:21:27] <furrywolf> they had to get more weights before mine broke.
[00:21:42] <furrywolf> the design would have sucked horribly in real life, but it wasn't real life, it was designing for a very specific test...
[00:22:27] <zeeshan-laptop> remember
[00:22:27] <zeeshan-laptop> the idea was to laser cut this
[00:22:28] <zeeshan-laptop> with as little parts as possibe
[00:22:33] <zeeshan-laptop> like making it big!
[00:23:13] * furrywolf doesn't remember it ever being mentioned before
[00:23:39] <zeeshan-laptop> im laser cuttig it! :P
[00:23:41] <zeeshan-laptop> you can see!
[00:24:16] <furrywolf> lol
[00:24:21] <furrywolf> bbl, time for me to head to work

[00:24:52] <zeeshan-laptop> http://i.imgur.com/6VgYNn6.gifv
[00:24:57] <zeeshan-laptop> think a sliding door is better
[00:25:10] <zeeshan-laptop> or a door on a piano hinge from the top
[00:25:48] <andypugh> Sliding is common
[00:25:55] -!- dagjomar has quit [Remote host closed the connection]
[00:25:57] <Bushman> i want a laser head :(
[00:26:03] <zeeshan-laptop> if it was your lathe
[00:26:05] <zeeshan-laptop> which one would you do
[00:26:17] <andypugh> A lift-up 2-part top might be better for access
[00:26:19] -!- tinkerer has quit [Quit: Leaving.]
[00:26:26] <zeeshan-laptop> yea
[00:26:47] -!- swingley has quit [Ping timeout: 252 seconds]
[00:27:31] <andypugh> zeeshan-laptop: I might be tempted by a gas-strut lift-up like http://www.1stmachineryauctions.com/media/lot/903044d574cba5240c165ad5742459f8e240410a.jpg
[00:28:03] <zeeshan-laptop> i like the 2 part idea
[00:28:06] <zeeshan-laptop> cause my lathe is long
[00:28:23] <zeeshan-laptop> might get annoying to lift it up again and again during tool change
[00:28:36] <Bushman> piano hinge is a bad idea... make it fancy, like pull up thing http://www.dom.pl/wp-content/uploads/2011/08/drzwi-podnoszone-pionowe.jpg
[00:28:46] <Bushman> not bad, just not cool :P
[00:28:49] <zeeshan-laptop> piano hinge is simple
[00:28:50] <zeeshan-laptop> :)
[00:28:54] <zeeshan-laptop> need a functional enclosure
[00:28:58] <zeeshan-laptop> that wont get annoying to use
[00:29:58] <Bushman> this type is functional, it gets the door out of the way without making you to step back a lot
[00:30:14] <Bushman> the sliding door is simplier in that case tho
[00:30:19] <zeeshan-laptop> it also looks like a hazard to bang my head against
[00:30:20] <zeeshan-laptop> lo
[00:30:21] <zeeshan-laptop> :D
[00:30:31] <zeeshan-laptop> sliding seems more convienient
[00:30:35] <Bushman> or you could make a sliding door half on piano hinge door front
[00:30:36] <zeeshan-laptop> ill just make the fixed door removable
[00:30:44] <zeeshan-laptop> incase i need to service
[00:30:52] <Bushman> ^
[00:31:12] <Bushman> sliding on bigger piano-hinged
[00:31:31] <andypugh> Think about drainage, you need the overlaps all in the right directions to deflect coolant
[00:31:40] <Bushman> you've got both, convenience and accessibility
[00:32:12] <Bushman> andypugh: i'm sure he thought about that :P
[00:32:27] <andypugh> No, surely not :-)
[00:32:47] <Bushman> well, i would. don't see a reason he wouldn't

[00:33:49] <andypugh> I was more thiinking in terms of secondary things like making sure coolant doesn’t wash brass swarf into the runners.
[00:33:53] <Bushman> damn it, can't find the stepper i slavaged from old deskjet printer
[00:34:11] <Bushman> i could sworn it had a shaft around 4mm
[00:34:59] <andypugh> I have some steppers on my desk with 6.3mm _bodies_
[00:35:07] <Bushman> andypugh: it doesn't if you use some sort of upside-down runners (which i would probably use, or made covers)
[00:35:20] <Bushman> 6.3mm bodies? hmm...
[00:35:35] <Bushman> i have a stepper right here that has shaft of that diameter lol
[00:36:13] <andypugh> I have yet to find a use for the baby ones
[00:36:14] -!- pjm has quit [Ping timeout: 246 seconds]
[00:36:26] <Bushman> make a baby CNC
[00:36:42] <Bushman> like 1:10 model
[00:36:44] <Bushman> :P
[00:36:51] <Bushman> fully functional of course
[00:36:59] <Bushman> with tiny routing bits
[00:37:17] <Bushman> engraving shit on tiny stuff
[00:37:19] <Bushman> :D
[00:37:28] <zeeshan-laptop> ill likely do the piano hinge method
[00:37:36] <zeeshan-laptop> then i dont i have to deal with chips getting in the channels
[00:38:29] <Bushman> use thin round rods and brass bushings for slides as guides
[00:38:41] <Bushman> no chips in channels cause no channels
[00:38:43] <Bushman> :D
[00:40:50] <andypugh> How about a tambour like a roll-top dsk :-)

[01:18:06] <Tom_itx> win7 64 won't install any of my programs win7 32 installed 99% so far
[01:18:45] <Jymmm> Not sure why one would use Win7 at all, but eh
[01:18:57] <Tom_itx> because xp is eol
[01:19:02] <Jymmm> so?
[01:19:08] <Tom_itx> and won't boot on this MB
[01:19:18] <Jymmm> wont boot?
[01:19:23] <Tom_itx> won't install
[01:19:56] <Jymmm> That seems strange,
[01:20:07] <Jymmm> But I probably know why too
[01:20:31] <Tom_itx> because the board doesn't support it
[01:20:57] <Jymmm> Uh, no. that's not it

[01:28:03] <Jymmm> I see no mention of XP being supported or not.
[01:28:27] <Tom_itx> my experience, if it doesn't say it, it doesn't
[01:28:32] <Jymmm> That's like saying ubuntu wont work because it doesn't say it's supported.

[01:54:01] <furrywolf> installing XP on anything internet-connectable is a very bad idea
[01:54:32] <Jymmm> not any more than anything else
[01:54:59] <furrywolf> yes, more than anything else. well, not more than win98...
[01:55:23] <furrywolf> microsoft stopped releasing security patches for XP a while ago. there are known, unpatched vulnerabilities.
[01:55:38] <Jymmm> Most of the bugs after 10+ years are known. Say that about that 30 day release no matter what schedule
[01:56:02] <roycroft> firewalls ameliorate the exposure signficantly
[01:56:16] <roycroft> and safe browsing, of course
[01:56:21] <Jymmm> not really
[01:56:27] <roycroft> yes, really
[01:56:31] -!- micges has quit [Quit: Ex-Chat]
[01:56:38] <Jymmm> you can think that all you want.
[01:56:45] <roycroft> i hardly ever use windows, because it's too difficult to deal with for the most part
[01:56:52] <furrywolf> you shouldn't be browsing from whatever single-purpose machine you needed to install XP for. heh.
[01:56:53] <roycroft> but i have some applications that only run on windows
[01:57:03] <roycroft> and one in particular that only runs on xp
[01:57:09] <roycroft> well, it runs on vista too
[01:57:13] <Jymmm> VM's ftw
[01:57:15] <roycroft> but vista is a non-starter
[01:57:19] amnesic_away is now known as amnesic
[01:57:22] <roycroft> yes, i run it in a vm
[01:57:33] <furrywolf> and if you do browse, don't use IE. IE on XP has known, unpatched, already-exploited-in-the-wild vulnerabilities.
[01:57:33] <roycroft> and i do connect it to the internet when i have to
[01:57:39] <roycroft> and i'm very careful what i do

[01:58:16] * furrywolf has never found VMs useful
[01:58:31] <roycroft> i use vms all the time
[01:58:41] <roycroft> we're moving most of our producting servers into vms
[01:58:44] <furrywolf> I've tried running windows in one, but the system requirements are such that it can't run usefully.
[01:58:57] <roycroft> *shrug*
[01:59:05] <roycroft> they run as fast as they would run on the raw hardware
[01:59:22] <roycroft> sounds like you haven't used a modern hypervisor
[01:59:23] <furrywolf> so I just have a pair of single-purposes boxes running windows for the two windows programs I have.
[01:59:43] <furrywolf> I don't own a computer with a modern hypervisor, nor enough ram to run windows alone, much less under another OS.
[01:59:54] <furrywolf> well, XP would run in the ram fine...
[02:00:03] <roycroft> i do most of my new sever builds in vms first before i deploy on the production machine
[02:00:21] <roycroft> when the production version will be a vm i can just copy it over to the new machine when it's built and configured
[02:00:31] <roycroft> when the production version will run on raw hardware the vm is a prototype
[02:00:37] -!- Valen has quit [Remote host closed the connection]
[02:00:47] <roycroft> my changelogs allow me to accurately replicate the development work very quickly
[02:01:12] <roycroft> virtualization has really revolutionized several industries
[02:01:35] <roycroft> it's made clusting 100x easier
[02:02:36] <roycroft> it's not new technology at all
[02:02:41] <roycroft> it's rediscovered technology
[02:02:51] <roycroft> ibm were doing virtualization on their mainframes in the '60s
[02:03:10] <furrywolf> I was wrong. apparantly this box does have a modern hypervisor, or at least there's a vmx in the cpu flags.
[02:03:55] <roycroft> well it has the vmx extensions that allow hypervisors to run more efficiently
[02:04:32] <roycroft> most of my servers don't have vmx support, but they still run really fast
[02:04:39] <roycroft> you have to provision them right though
[02:04:56] <roycroft> i don't oversubscribe cpu cores or memory
[02:05:04] <roycroft> that's a big mistake a lot of people make
[02:05:15] <furrywolf> I have 2 slow cores and 3GB of ram. :)
[02:05:17] <roycroft> and something my boss and i argue about a lot
[02:05:34] <roycroft> if i have a sever with 8 cores and 32GB of ram i'll provision 8 virtual machines with 4GB each
[02:05:36] <roycroft> and nothing more
[02:05:57] <roycroft> he, of course, being a boss, wants me to load up about 60 vms on that same machine
[02:06:24] <roycroft> that kind of virtualization also requires lots of spindles
[02:06:25] <furrywolf> the only use I've ever seen for virtualization on servers is when customers need system access, like Linode and etc... otherwise it makes far more sense to only run each service once.
[02:06:44] <roycroft> it makes managing them so much easier
[02:06:50] <roycroft> want to do an os upgrade?
[02:06:57] <roycroft> take a snapshot of your running machine
[02:07:01] <roycroft> clone the snapshot
[02:07:03] <roycroft> upgrade it
[02:07:04] <roycroft> test
[02:07:14] <roycroft> when it's all ready cut over to it as the production vm
[02:07:40] <roycroft> your downtime is a couple minutes vs. several hours
[02:07:58] <furrywolf> or have separate production and devel servers.
[02:08:05] <Jymmm> And when the upgrade fucks up, revert to snapshot and back where you were in 20 seconds or less =)
[02:08:10] <roycroft> i guess you're unwilling to understand
[02:08:16] <roycroft> so i'll just shut up now
[02:08:34] <roycroft> people who make decisions based on no information are impossible to convince otherwise
[02:08:48] <furrywolf> you just mentioned running 8 VMs on one machine. that's a lot more than just a devel/production switch.
[02:09:11] <Jymmm> nt really, we ran 28
[02:09:31] <Jymmm> not*
[02:10:21] <furrywolf> and involves using 8 times the resources, having to manage 8 times the upgrades and patches (except for when they're clones of each other, of course - but that's pointless already), etc.
[02:10:49] <Jymmm> Not at all, VM has tools that unifies all that.
[02:11:37] <ssi> roycroft: lol
[02:12:02] <furrywolf> I think VMs are great when you have users that need/want root access but don't need the resources to justify a dedicated machine... I just don't think that's all that common. I love my Linode, for example, but most people just want some unseen administrator to do all the work for them, and would be perfectly happy with just a home directory...
[02:12:25] -!- nerdfiles has quit [Ping timeout: 264 seconds]
[02:12:53] <Jymmm> furrywolf: Hold on, a virtual hst and virtual machine are NOT the same thing.
[02:12:56] <Jymmm> host*
[02:13:35] <furrywolf> I'm using a virtual host as an example of a good use of a virtual machine.
[02:14:14] <roycroft> a vps should be oversubscribed to hell and back
[02:14:31] <roycroft> for $25/month (average price) all the user is paying for is bandwidth
[02:14:40] <Jymmm> and power
[02:14:44] <Jymmm> wattage
[02:14:45] <roycroft> any cpu cycles the get are a bonus
[02:14:50] <furrywolf> no, they shouldn't. I had a provider do that. it pissed me off muchly. if I wanted to run a 386 on a modem, I'd do that myself.
[02:15:19] <furrywolf> they eventually went out of business. pissing off customers is not a good way to stay in business.
[02:15:20] <roycroft> vps are for pr0n and war3z
[02:15:56] <roycroft> so i guess the other thing the user is paying for is a hope to not get caught
[02:16:19] <furrywolf> I have no porn on my vps (nor at home either), and the closest thing I have to "warez" is a copy of the programming software for the motor controller on my electric cart, which the manufacturer tries to claim only dealers are allowed to have, so you have to pay the dealer every time you want any trivial setting tweaked.
[02:16:20] <roycroft> i'm assuming that's what you mean by virtual host
[02:16:37] <roycroft> virtual host usually refers to web/email services for a domain on a shared machine
[02:16:58] <furrywolf> "virtual private server" is the term you're looking for.
[02:17:16] <roycroft> yes, a vps
[02:17:18] <roycroft> as i said
[02:18:06] <furrywolf> I don't use windows, so I don't have a need for warez, and I don't like porn. :P
[02:18:57] <roycroft> well a vps is designed to be oversubscribed heavily
[02:19:03] <roycroft> and everyone knows that
[02:19:19] <roycroft> i hate them, personally
[02:19:22] <furrywolf> and, as far as I'm concerned, if you pay for a piece of hardware, you should have the right to adjust settings on said piece of hardware. if the manufacturer thinks otherwise, tough for them.
[02:19:33] <roycroft> but if you're using that as an example of virtualization, it's a poor one
[02:19:49] <roycroft> what has that to do with the price of tea in china?
[02:20:15] <furrywolf> even trivial things like current limits, acceleration, braking, turn rates, input configuration, etc, they want you to pay the dealer for... so I have no problem at all hosting said program and sending it to others. heh.
[02:20:27] <roycroft> oh
[02:20:39] <roycroft> that is not germane to the discussion about virtual machines
[02:20:43] <roycroft> it's a beef you have with a vendor
[02:21:00] <roycroft> that's all part of your license agreement
[02:21:05] <roycroft> if you don't like the license don't buy the product
[02:22:12] <furrywolf> lol
[02:22:32] <CaptHindsight> http://www.3ders.org/articles/20150316-swiss-scientists-to-test-3d-printed-nose-implants-on-sheep.html why do sheep need human shaped noses?
[02:22:56] <roycroft> why did michael jackson need a white person nose?
[02:23:22] <furrywolf> right, and you're probably one of those people who thinks anyone who doesn't like their government should leave instead of try to change it, anyone who doesn't like their religion should go live on the south pole, etc. if you don't like something, do everything you can to make it better. if you're not part of the solution, you're part of the problem.
[02:23:27] <roycroft> personally, i thought he was better looking when he was black
[02:23:44] <roycroft> i constnantly try to change my government
[02:24:05] <roycroft> if i were "one of those people" i'd have left this country for a place with a more sane government long ago
[02:24:06] <CaptHindsight> I didn't know that sheep were so concerned about their appearances
[02:24:55] <furrywolf> CaptHindsight: sheep are very concerned about their appearances. that's why they're always seen at the mall, always have to have a fancier watch than their neighbors, ... oh, you mean the animal.

[02:37:59] <roycroft> i just went to turn the potatoes on the grill and found the propane tank was empty
[02:38:03] <roycroft> so i'll be hungry for a while yet
[02:38:18] <roycroft> i hate it when that happens
[02:39:26] * roycroft is on his last tank now, too - he needs to go fill a bunch this weekend
[02:40:01] <furrywolf> pick up an old regulator off a house trailer with two inputs
[02:40:44] <furrywolf> http://www.nysmartgenerators.com/wp-content/uploads/2014/07/Fairview-Dual-Tank-Kit.jpg looks like that
[02:40:50] <roycroft> that might not be a bad idea
[02:40:56] <roycroft> since i grill quite regularly
[02:40:58] <furrywolf> note the tanks go to separate inputs. don't get one that just has a tee.
[02:41:07] <roycroft> and i can pretty easily remodel my grill to fit two tanks inside
[02:41:55] <roycroft> i would need one that auto-switches before the flame goes out
[02:41:56] <furrywolf> http://www.tejassmokers.com/images/manchangeoverssoverbraid.jpg bad design. don't get.
[02:42:04] <roycroft> otherwise it would not matter
[02:42:11] <furrywolf> they all auto-switch before the flame goes out.
[02:42:24] <furrywolf> failing to do so is a major safety hazard, and would get them sued. :)
[02:42:25] <roycroft> then it's something to consider
[02:42:48] <roycroft> and i assume there's some kind of indicator that it's switched over
[02:42:56] <furrywolf> having the gas go off then turn back on while all the valves are still open is a bad thing.

[02:43:19] <roycroft> so i could monitor and swap tanks before they both are empty
[02:43:35] <roycroft> i probably go through a tank per month on the grill
[02:44:16] <roycroft> so several times per year dinner is delayed if i'm cooking spuds or something else that takes a long time, and i'm not out monitoring constantly
[02:44:59] <roycroft> a thermocouple and a raspberry pi with a wifi dongle would do the job too
[02:45:06] <furrywolf> the one I have has a pressure indicator on it that shows the tank the switch is set to, even if it's switched over to the other tank... so if you see it's turned red, you know the tank you were using is empty, and you're now running off the other one.
[02:45:07] <roycroft> i don't mind if the flame goes out
[02:45:10] <roycroft> as long as i know right away
[02:46:24] <roycroft> for that matter, setting the propane tank on a bathroom scale would be fine
[02:46:32] <roycroft> i check the scale when i'm ready to turn on the grill
[02:46:41] <roycroft> and would know when the tank is close to empty
[02:47:12] <roycroft> i can probably get a bathroom scale for $3.99 at the goodwill
[02:47:13] <furrywolf> I had a grill with that built-in once... the tank table was hinged on one side, and the other side had a spring, with a steel rod to a pointer.

[02:48:17] <roycroft> good thing we're on summer time now, and my body hasn't fully adjusted yet
[02:48:46] <roycroft> the dual tank switching thing is interesting, though
[02:48:59] <roycroft> i have a dozen propane tanks, so i can easily spare one for that

[02:52:01] <roycroft> plus, it results in good food!
[02:52:03] <furrywolf> I have a switch somewhere with fiber uplink, does that count? :)
[02:52:26] <furrywolf> I find cooking to be work, and the result is nothing but food, which you eat and it's gone.

[03:25:31] <roycroft> from a what-would-make-the-world-a-better-place point of view
[03:25:34] <furrywolf> I agree.
[03:25:45] <furrywolf> people rarely get stoned and beat their wives.
[03:25:49] <roycroft> and a big problem with marijuana being illegal is that hemp is also essentially illegal
[03:25:56] <roycroft> and hemp is an incredibly useful plant
[03:26:07] <furrywolf> many of the problems with marijuana would go away if it were legal.
[03:26:15] <roycroft> it is here in oregon :)
[03:26:18] <roycroft> well, starting 1 july
[03:26:22] <cradek> are ... now that it is

[03:26:35] <cradek> yep slooooowly
[03:26:46] <furrywolf> like all the associated crime. there's only drug crime because of drug laws. (with the exception of meth - it seems to damage your brain such that you no longer qualify as human)
[03:26:46] <roycroft> the problem is not marijuana per se

[03:27:39] <roycroft> that's the main reason it's still illegal
[03:27:57] <roycroft> if you're a brown person and you're caught with a few joints it's a felony, and you lose your right to vote
[03:28:02] <Tecan> isnt it legal in washington now too ?

[03:29:47] <roycroft> we're the first state in the nation to implement that law
[03:30:16] <furrywolf> doesn't matter what color you are.
[03:30:32] <roycroft> in many states it does matter

[03:31:06] <furrywolf> pot is pretty much legal here... the cops only care if you have a huge grow or a grow on public land.
[03:31:08] <roycroft> and our new motor voter law stipulates that if we ever grant provisional licenses to undocumented aliens they will not be registered to vote
[03:31:19] <furrywolf> and even for a huge grow, as long as it's on your property, you just get probation anyway.
[03:31:27] <cradek> furrywolf: you sound white
[03:31:33] <roycroft> the term of the sentence is not the issue
[03:31:38] <roycroft> it's whether it's a felony or not
[03:31:48] <roycroft> if you're convicted of a felony you lose your right to vote
[03:31:50] <cradek> a cop's discretion is not a good bet for everyone
[03:31:59] <furrywolf> I don't know of anyone who's been given a felony for growing here.
[03:32:09] <roycroft> and in many jurisdictions that is being used in lieu of the unconstitutional jim crow laws
[03:32:20] <furrywolf> it's only a felony if you also have meth and a stash of guns, which is pretty common. heh.
[03:32:52] <cradek> roycroft: the roberts court is working on bringing those back, don't worry
[03:32:58] <furrywolf> my favorite is how they "destroy" grow equipment... they cut the plugs off the ballasts. at the plug end. and leave it all intact.
[03:33:21] <furrywolf> aka "we don't give a fuck, but someone says we have to"
[03:34:06] <roycroft> roberts does not scare me as much as i thought he would
[03:34:17] <furrywolf> come to think of it, I haven't heard of a pot bust of any kind in a while, where other drugs weren't also involved... they might have just stopped caring entirely.
[03:34:19] <roycroft> scalia, thomas, alito, and sometimes kennedy concern me a *lot*

[03:37:53] <furrywolf> oh, they're getting rid of that? makes sense.
[03:37:56] <roycroft> and scalia, in his seethingly sarcastic manner (i'm being generous, otherwise i would have to believe that he's completely disconnected from reality) said that "congress can just pass new legislation to fix this"
[03:38:07] <roycroft> just as he said this week about the aca case
[03:38:16] <roycroft> but that
[03:38:23] <roycroft> is not the case the bothers me the most
[03:38:28] <roycroft> citizen's united is the big one
[03:38:40] <roycroft> and i hold roberts responsible for that
[03:38:44] <roycroft> don't think i'm a fan of his
[03:38:47] <furrywolf> making some states but not others subject to extra work doesn't make any sense. either make all do it, or none.
[03:38:58] <roycroft> i'm just pleasantly surprised that he's not a total wingnut
[03:39:18] <roycroft> making states that don't suppress voters do a bunch of extra work does not make sense
[03:39:39] <roycroft> those that have been proven to violate voter rights should bear the burden completely
[03:40:00] <furrywolf> when? 50 years ago?
[03:40:12] <roycroft> i agree in principle with the decision
[03:40:20] <roycroft> but i'm pretty realistic/pragmatic
[03:40:36] <roycroft> there's *NO WAY* this congress is going to pass a new voter rights act
[03:40:43] <furrywolf> I don't consider it "nuking the voting rights act", that's for sure.
[03:40:48] <roycroft> they can't even pass a fucking budge without major drama
[03:40:55] <roycroft> it completely gutted the meat of the act
[03:41:42] <cradek> furrywolf: it sounds like you have not read much about Shelby yet...
[03:42:01] <roycroft> i don't think the congress should be responsible for deciding who needs should be required to get approval for their voting law/redistricting changes, btw
[03:42:09] <roycroft> it should be an independent commission
[03:42:16] <roycroft> congress should be hands off
[03:42:26] <roycroft> delegate, and get the politics out of it
[03:42:36] <furrywolf> I want a law that says religious people aren't allowed to vote. If you're obviously mentally incompetent and just do what churches tell you, it's just like selling your vote, and illegal.
[03:42:43] <cradek> you might say the same about districting

[03:48:23] <roycroft> i think the ones that would not, such as the south and the great wasteland, would wake up after the teat is gone
[03:48:33] <roycroft> and figure out how to conduct themselves reasonably
[03:48:52] <furrywolf> sure it does. and I think we should have monthly votes, doing with secure online voting. all voters are given a non-networked electronic device that signs a manually entered ballot hash, with the result typed in, to prevent any chance of malware etc placing votes.
[03:48:56] <zeeshan|2> LeelooMinai: lol
[03:49:25] <LeelooMinai> It has some EPFA coating or something like this - what a bastard:)
[03:50:00] <roycroft> and believe me, i would be all for continuing to suckle the less enlightened parts of the country if i thought there was a chance that they would learn while still being propped up
[03:50:18] <furrywolf> with monthly votes, even small things could be placed on the ballot without a huge hassle, and with the ability to recall a politician a month after they fuck up, they'll have a lot more incentive to actually do what the voters say they should be doing.
[03:50:19] <roycroft> furrywolf: people don't even know how to elect a functional congress
[03:50:46] <roycroft> there's no way in hell they can be trusted en masse to understand the nuances of the legislation that's required to make a large nation functional

[04:08:56] <roycroft> to be slightly on topic for once, the us-made jacobs chuck that i recently put on my mill-drill to replace the chinese one that came with it is amazing
[04:09:05] <roycroft> it's really a night and day difference in quality
[04:09:36] <LeelooMinai> roycroft: If you bought an expensive Chinese chuck it would probably be better than that Jacobs:)
[04:09:58] <roycroft> mayhap
[04:10:05] <roycroft> i've never seen such a chinese chuck though
[04:10:15] <roycroft> but i won't argue that they don't exist
[04:10:38] <LeelooMinai> Chinese keep good stuff for themselves probably
[04:10:43] <zeeshan> new jacobs is made in china
[04:10:50] <zeeshan> thats why theyre shit

[04:11:48] <zeeshan> vs albricht chuck
[04:11:48] <roycroft> really low-end tooling moves around
[04:11:54] <zeeshan> no comparison :P
[04:11:59] <roycroft> after the war it was japan that pumped out cheap crap

[04:13:27] <zeeshan> oh they're way better
[04:13:38] <roycroft> once india and vietnam start making high quality stuff, the bottom of the barrel will probably move to sub-saharan africa

[04:13:54] <LeelooMinai> I was doing some guitar research recently and guitars made in Korea are better than the Chinese ones
[04:14:52] <LeelooMinai> I don't know... Africeans to not seem to have much paitience for precision work, like Asians
[04:15:08] <LeelooMinai> Maybe it's because it's too hot there:)
[04:15:17] <roycroft> which is why the cheap crap stuff is going to move there
[04:15:49] <LeelooMinai> I already imagine "Made in Africa" being new "Made in China"
[04:16:32] <roycroft> currently it's "made in india"
[04:17:19] <zeeshan> i think india is leaps ahead of china
[04:17:21] <zeeshan> in precision stuff
[04:17:38] <zeeshan> for example glanze tooling
[04:17:42] <zeeshan> good stuff!
[04:17:47] <roycroft> i've never seen precision stuff from india
[04:17:54] <zeeshan> it's not as famous
[04:18:03] <zeeshan> they mostly export to places like the middle east
[04:18:05] <roycroft> i accidently bought some files a while back that were made in india
[04:18:10] <zeeshan> not sure why not to north america
[04:18:11] <LeelooMinai> I have seen some clothes from India and that's all:)
[04:18:15] <roycroft> i think they had a rockwell hardness of about 39
[04:18:18] <zeeshan> LOL
[04:18:20] <zeeshan> nice
[04:18:29] <zeeshan> btyw i bought the nicholson files made in mexico
[04:18:30] <roycroft> and i had to debur them before i could wipe them across my metal
[04:18:35] <zeeshan> theyre 100x better than my old usa made ones
[04:18:39] <zeeshan> but that could be cause theyre worn
[04:18:46] <zeeshan> the guys that talk shit about the new files are retarded
[04:18:52] <zeeshan> they clearly havent tried em
[04:19:17] <roycroft> i bought some nicholson french rasps that were cryogenically treated by a third party
[04:19:21] <roycroft> amazing rasps
[04:19:24] <zeeshan> i tried their mill file, flat bastard file, half moon, and round
[04:19:43] <zeeshan> whats a rasp file used for?
[04:19:47] <zeeshan> it looks like its for wood
[04:19:49] <zeeshan> cause of the cut
[04:19:57] <roycroft> yes, for wood
[04:20:03] <zeeshan> ive used it on fiberglass
[04:20:04] <roycroft> and the "french" style are hand-cut
[04:20:08] <roycroft> so they're random
[04:20:09] <zeeshan> but not sure if that is what it's meant for
[04:20:14] <zeeshan> ah
[04:20:21] <roycroft> i do a lot of woodworking as well as machining
[04:20:28] <zeeshan> im putting together a bridge right now
[04:20:36] <zeeshan> i dont know if you saw what i posted earlier
[04:20:46] <zeeshan> how long does elymer's white glue take to remove weight from the joint?
[04:21:01] <zeeshan> some say 15 min, some say 30 min, some say 1 hour
[04:21:03] <zeeshan> some say a day
[04:21:04] <zeeshan> lol
[04:21:13] <roycroft> i don't use white glue
[04:21:20] <zeeshan> ts all i had
[04:21:27] <roycroft> so i have no valid say

[06:31:46] <archivist> what are you using LVDT for?
[06:35:49] <Cromaglious> touch sensor. I got 2 sensors for $30, now I just have to read them. Looks like with the NE5521 I can read them pretty easy and then I can use a Arduino nano to send it to the computer as a on off as well as a digital value.
[06:36:20] <Cromaglious> using the comparator in the Nano
[06:37:21] <archivist> I got a flatness testing jig with one, it includes a bargraph display, I used it on the mill for a while
[06:38:40] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=cnc+distance
[06:39:53] <Cromaglious> I could use one for the tool height setter and one for the touch sensor
[06:41:22] <archivist> I was intending to use a comparator on its output to set 0 on one axis, but never got around to do that
[06:42:22] <Cromaglious> I was gonna use the Nano to do basically the same thing.. though a comparator would be better responcse
[06:42:52] <Cromaglious> set active high or low depending on what mach3 or linuxcnc want.

[14:56:10] <CaptHindsight> if you can't move the spindle or the part then move the cutting edge

[15:02:20] <dirty_d> CaptHindsight, that wouldnt work though, because of the curve on the blade

[15:05:08] <ssi> I see

[15:09:36] <pcw_home> hmm not much help, did you just change the motherboard?
[15:09:38] <pcw_home> "A configuration error is preventing LinuxCNC from starting."
[15:10:21] <CaptHindsight> yes he did
[15:10:40] <CaptHindsight> oh "just"
[15:10:49] <maZer`-> yes mainboard ram and processor
[15:11:04] <maZer`-> does i do something wrong? :(
[15:11:17] <maZer`-> changed to stronger quad core, old one did many problems
[15:11:22] <CaptHindsight> did you change anything else?
[15:11:39] <CaptHindsight> new hard drive, new install of Linuxcnc?
[15:11:41] <maZer`-> no only cpu, main, ram
[15:11:46] <_methods> same board?
[15:11:52] <maZer`-> no new harddrive
[15:11:55] <maZer`-> no different board
[15:11:57] <_methods> or lol
[15:12:04] <maZer`-> no wait
[15:12:06] <_methods> yeah that's probably not gonna work
[15:12:09] <maZer`-> different mainboard
[15:12:09] <maZer`-> ;D
[15:12:40] <_methods> i'm suprised your computer even started up
[15:12:46] <_methods> impressive
[15:12:46] <maZer`-> also i changed mainboard, cpu, and ram
[15:12:54] <CaptHindsight> maybe new locations for SATA
[15:12:59] <maZer`-> yes started good installed ati drivers after
[15:13:02] <pcw_home> Umm I do that all the time
[15:13:10] <_methods> really?
[15:13:11] <maZer`-> no is booting well.
[15:13:23] <_methods> i've never had any luck swappin main boards on an existing install
[15:13:24] <maZer`-> also all files all harddisk are detected as same
[15:13:35] <pcw_home> swapping harddives from system to system tends to just work with linux
[15:13:48] <maZer`-> on windows is problem but linux ahci should be good ;D
[15:14:07] <maZer`-> hm :(
[15:14:19] <maZer`-> but is the problem visible on the startup logfile? :(
[15:14:29] <pcw_home> yeah I have about a dozen test machines (including a laptop) and swapping harddrives works fine
[15:14:29] <CaptHindsight> maZer`-: can you run the LiveCD and the latency test from it?
[15:14:58] <pcw_home> maybe post all of dmesg
[15:15:06] <pcw_home> (from boot)
[15:15:32] <CaptHindsight> unless he had some hardcoded sda sdb etc in his configs and the kernel has his drive at a new locations?
[15:15:55] <pcw_home> pretty unlikely
[15:16:11] <CaptHindsight> yeah, just thinking of possibilities
[15:16:30] <maZer`-> CaptHindsight ok i can try it
[15:16:39] <maZer`-> dmesg no problem
[15:17:39] <pcw_home> the latency test not working looks like some kind of real time issue

[15:19:28] <CaptHindsight> we never use FGLRX
[15:19:51] <pcw_home> maybe too new MB for kernel ( at one time RTAI had issues with newer multicore AMD CPUs)
[15:20:18] <maZer`-> mainboard is 3 years old :D
[15:20:21] <CaptHindsight> maZer`-: what APU and mainboard?
[15:20:21] <maZer`-> sorry
[15:20:21] <maZer`-> 5
[15:20:33] <maZer`-> no is old quad core from amd

[15:21:46] <pcw_home> yeah ISTR there were troubles with those

[15:22:08] <maZer`-> is there a way i can fix? :(
[15:22:21] <CaptHindsight> we used those all the time
[15:22:40] <pcw_home> with 2.6.32.122?
[15:22:50] <CaptHindsight> see how the liveCD runs
[15:23:01] <maZer`-> i got the 2.6.32 kernel
[15:23:43] <CaptHindsight> old kernel and old RTAI
[15:24:07] <maZer`-> hm :D
[15:24:14] <maZer`-> good idea to update it?
[15:24:22] <CaptHindsight> yeah
[15:24:23] <maZer`-> to version linuxcnc 2.6 ?
[15:24:51] <CaptHindsight> we can help you with any AMD issue with the new version
[15:25:04] <maZer`-> hehe great! :D
[15:25:06] <pcw_home> yeah try wheezy (linuxcnc iso is 2.6.x + wheezy)
[15:25:42] <CaptHindsight> we never bothered fixing the old RTAI and kernels

[18:30:20] -!- per_sonne has quit [Ping timeout: 256 seconds]
[18:32:12] <archivist> dirty_d, each maker of inserts has their own numbering scheme
[18:35:28] <FinboySlick> CaptHindsight: I don't understand what keeps the 'oxygenated' resin in place though.
[18:36:37] <CaptHindsight> FinboySlick: it moves around, the membrane is oxygen permeable
[18:38:21] <FinboySlick> But when the part itself lifts up, what fills the gap has to be regular resin if you want to 'print' it. The resin is only oxigenated if it touches the membrane?
[18:39:10] <FinboySlick> :s/oxi/oxy/
[18:39:10] <CaptHindsight> the resin won't cure if there is too much oxygen in it, so there is just a very thin (few micron) layer of resin that mixes with oxygen right on top of the membrane
[18:40:12] <CaptHindsight> as the part lifts away from the membrane this creates a low pressure area between the part and the membrane
[18:40:44] <CaptHindsight> gravity and this low pressure area draws resin into that space
[18:41:32] <FinboySlick> Yes, that part is fairly obvious. What I didn't get was that if the oxygenated resin was liquid too, nothing prevents it from filling the gap instead of printable resin.
[18:42:05] <CaptHindsight> the resin can only flow so fast into that area based on its viscosity, this is one limitation
[18:43:10] <FinboySlick> So vertical movement speed varies as a factor of contact area?
[18:43:42] <CaptHindsight> yes, they even mention it in the video, they slow down for larger areas
[18:45:10] <CaptHindsight> the layer that won't cure is actually in the several nanometers of thickness
[18:45:54] <CaptHindsight> it varies based on the amount of oxygen available and the size of the monomers and oligomers
[18:46:07] <CaptHindsight> this only works with free radical polymerization
[18:46:38] <CaptHindsight> cationic curing will stick to the membrane
[18:46:42] <FinboySlick> OK. I couldn't picture how it wouldn't end up mixing with the curable resin.
[18:46:51] <CaptHindsight> it doesn't get inhibited by the oxygen
[18:47:10] <CaptHindsight> the membrane is a sponge
[18:47:15] <CaptHindsight> filled with air
[18:47:45] <CaptHindsight> the pores in the membrane are too small for the monomers and oligomers to pass through
[18:48:00] <CaptHindsight> but oxygen goes right through it
[18:48:26] <CaptHindsight> osmosis with a very thick membrane
[18:49:18] <FinboySlick> I wonder if one could use aerogel as a membrane then.

[18:49:39] <CaptHindsight> aerogels are closed cell
[18:49:48] <CaptHindsight> the membrane is open cell
[18:50:26] <CaptHindsight> if you look at polymers under a microscope they aren't solid
[18:51:10] <CaptHindsight> some have large open spaces that oxygen can slip through
[18:51:48] <CaptHindsight> it's more like a jumble of strings than a solid mass
[18:51:59] <CaptHindsight> or pile of chains
[18:52:33] <CaptHindsight> you can't push through it but air can easily pass through
[18:53:36] <CaptHindsight> the way the B9 and other cheapo SLA printers work including the Form1 is they use a silicone film that traps oxygen
[18:54:32] <CaptHindsight> so they need the oxygen to be refreshed by wiping the silicone clear of resin
[18:55:20] <CaptHindsight> they also rely on the low surface tension of the silicone and/or ptfe combo used for the bottom of the vat
[18:59:07] <CaptHindsight> FinboySlick: TPX (PMP) and similar polymers are used for release films when molding epoxies, acrylics, urethanes etc
[18:59:55] <FinboySlick> OK.
[19:00:01] <CaptHindsight> hydrogels used for soft contacts also are oxygen and water permeable
[19:00:42] -!- Brunetty has quit [Quit: Follow me]
[19:01:23] <CaptHindsight> water is a great surface to cure non-polar resins on since it's polar and holds oxygen
[19:02:31] <CaptHindsight> the numbnuts in reprap confuse this with hydrophobic coatings
[19:03:08] <CaptHindsight> they seem to think hydro = any liquid
[19:03:51] <FinboySlick> Yeah. I didn't think it would work for resin myself but I did imagine an equivalent for resin would go a long way.
[19:04:50] <CaptHindsight> and the chemist (and i use the term loosely) at makerjuice doesn't believe in oxygen inhibition of free radical curing

[20:42:48] <LeelooMinai> I think I need to make up bae and maximum rpm so the drive will use 60-400Hz for that range.
[20:42:49] <JT-Shop> hmm the GS2 will do 400Hz
[20:42:58] <Cromaglious> Hy series or SL series?
[20:43:13] <LeelooMinai> I won't get real rpm display, but I will get 60-400Hz
[20:43:51] <LeelooMinai> At least that's the only possibility that comes to my mind now
[20:43:52] <Cromaglious> ahh found the manual
[20:44:19] <JT-Shop> but it only goes to 9999 RPM
[20:44:45] * JT-Shop puts the GS2 manual back
[20:44:47] <LeelooMinai> RIght, that's why I think I need to make up some numbers

[23:06:56] <furrywolf> and, despite being advertised as 50W, it only draws 20W.
[23:07:28] <furrywolf> I purchased from a fucking US seller, in the same state, with USPS shipping, to make sure I got the correct item, quickly, in one piece. Instead I get the wrong item, a week later, smashed.

[23:16:54] <furrywolf> I've been leaving way too much negative feedback on ebay lately.
[23:17:11] <furrywolf> why does society seem to go progressively downhill every year?
[23:17:59] <andypugh> furrywolf: Because you are getting progressively older?
[23:19:05] <andypugh> I bet Adam was complaining about “The youth of today” back when Cain killed Abel. Possibly with some justification in that case.
[23:19:22] <furrywolf> no, I don't think my age causes people to falsely advertise goods.
[23:22:23] <jdh> Cromag: what's wrong with it?

[23:32:24] <SpeedEvil> furrywolf: also - if it arrives significantly different from advertised, do the ebay process for that

[23:32:39] <furrywolf> 50W LED floodlight.
[23:32:44] <SpeedEvil> ah
[23:32:46] <furrywolf> (yes, I ordered the 50W one)
[23:33:26] <furrywolf> arrived smashed so badly one of the corners is ripped off (because they shipped UPS even though the listing says USPS), and it only draws 20W.

[23:34:12] <SpeedEvil> I've taken to doing 'video unboxings' of all things recieved.
[23:34:25] <SpeedEvil> Greatly cuts down shipment debate issues
[23:35:07] <furrywolf> I've taken to only buying from places that do not ship UPS. Mostly eliminates shipping damage issues. This listing says in at least three places that it ships USPS, but the asshole shipped UPS anyway.
[23:35:28] <furrywolf> I don't know if I've ever had USPS smash an item. I don't know if I've ever had UPS not smash an item.
[23:36:40] <SpeedEvil> Have you ever accidentally killed a UPS driver?
[23:37:04] <furrywolf> no, and when I do, it won't be an accident.
[23:39:09] <furrywolf> they once ran over an air compressor I bought. tire tread mark on the box and all.
[23:39:18] <furrywolf> I've watched them unload things by pushing them off the back of the truck.
