<B0101> Hi
<azonenberg_lab> Hi
<azonenberg_lab> Playing with making probe tips still
<azonenberg_lab> They're all decently shapr but getting really fine points is tricky
<azonenberg_lab> needs to make a controller board
<B0101> ooh...
<azonenberg_lab> i can easily hit 2.5um tips, 1.5 is doable under good conditions
<azonenberg_lab> but i want like 500nm
<B0101> hmm....
<B0101> WTH??? Copyright claim???? For MY lab notes????
<azonenberg_lab> ?
<azonenberg_lab> Someone else is claiming your notes are infringing something?
<B0101> Yup
<azonenberg_lab> o_O
<azonenberg_lab> Where did you have them posted?
<B0101> I only keep them in a Member accessible web site
<azonenberg_lab> Lol
<B0101> Now its been taken down
<azonenberg_lab> wtf... file a counterclaim
<azonenberg_lab> Did they provide detail as to the exact offending material or just say "the whole site"
<B0101> They told me the file name is: lab_paper_1.pdf
<B0101> If I am not mistaken: THAT was notes that I taken from MY EXPERIMENT
<B0101> I am told nothing else...
<B0101> I am not even told who the claimant is!!!
<azonenberg_lab> Is this from your web host or what?
<B0101> From my web host....
<azonenberg_lab> Who is US based i assume?
<B0101> its an SG web host
<azonenberg_lab> well if its a DMCA claim there is a specifically formatted response to a takedown request, saying you do not believe the content is infringing
<azonenberg_lab> Which is risky if it IS, because you open yourself to a lawsuit - but if the claimant does not file a suit within a few weeks the content must be restored
<B0101> azonenberg_lab: This isn't the first time....
<azonenberg> B0101: What?
<azonenberg> They've done it before?
<B0101> I created a encryption program 2 years ago... they took it down because of a copyright claim
<azonenberg> But they didnt tell you the claimant?
<azonenberg> Thats pretty messed up
<B0101> They never
<azonenberg> Time to find a new web host IMO
<azonenberg> One that will actually tell you who's making the claim and give you a fair fight
<azonenberg> They are obligated to take it down immediately on recieving the notice no matter what
<azonenberg> But they should give you the opportunity to make a counterclaim
<B0101> I know... I have prepared the backup....
<B0101> and I will move ASAP
<azonenberg> DMCA claims have a history of being abused
<azonenberg> i think ars technica or wired had their facebook page shut down after a DMCA claim
<azonenberg> And it took them quite a while to get it back up
<B0101> which sucks...
<azonenberg> fb didnt even tell them what the offending content was or who had filed the claim
<B0101> sucks even more
<B0101> Singapore ISP's will do anything to prevent you from hosting a server at your home....
<azonenberg> even in the USA there are problems with that
<azonenberg> But usually they dont block odd high ports
<azonenberg> Just well known ones
<azonenberg> Still, its annoying enough that I plan to move my main server to an offsite datacenter soon
<B0101> My ISP made sure that all their clients share the ISP's gateway server's External IP
<azonenberg> They're using NAT?
<B0101> Yup
<azonenberg> Which to me probably means they're out of ip addresses
<azonenberg> and are too lazy to deploy v6
<B0101> up
<B0101> *yup
<B0101> and there are only 3 ISP's here in singapore
<azonenberg> And they all collaborate to ensure insanely high prices etc?
<B0101> this is my second ISP...
<B0101> yup
<B0101> And I am tired with their lies...
<B0101> Service: Not good, Prices: REALLY HIGH!!!
<azonenberg> lol, sounds typical of most companies in telecom these days
<B0101> My ISP had a lot of downtimes...
<B0101> and they blamed it on my router.... my server... my whatever
<azonenberg> My home isp has trouble too, which is why i am moving my servers offsite
<azonenberg> To a proper datacenter on a 100mbit pipe
<azonenberg> With i think four or five nines uptime guaranteed
<B0101> my ISP told me that i will have a 1 Gigabyte per second speed
<B0101> Not kiddinf
<azonenberg> :P
<B0101> *kidding
<azonenberg> I've been on *real* gigabit pipes
<azonenberg> They're nice
<B0101> but my speed is about 1MBPS
<azonenberg> Fastest speedtest i ever hit was 250 Mbps down and 150 up
<azonenberg> And i think the test server was the bottleneck
<B0101> My speed test: download speed = 6.50 down
<azonenberg> This is on campus in a lab thoguh
<azonenberg> At home i get horrible speeds
<B0101> Now I am watching a show similar to Good morning America
<B0101> Ah 2012 B.S
<B0101> they don't need to show it on TV
<B0101> hows your mask experiment by the way??/
<azonenberg> B0101: Not doing mask stuff today
<azonenberg> Probe fab
<azonenberg> And right now i'm actually battling one of my servers which doesnt seem to want to talk to me over the network
<azonenberg> Seems to be booting, i hear the POST beep
<azonenberg> and am not in the mood to haul one of my monitors across the house to debug it
<azonenberg_lab> hi Harold_parker
<Harold_parker> sup  azonenberg_lab
<Harold_parker> how goes mate?
<Harold_parker> :)
<azonenberg_lab> As of now? Getting annoyed with one of my servers
<azonenberg_lab> its having trouble booting for reasons unknown and i'm not in the mood to drag out a monitor to debug
<Harold_parker> :(
<Harold_parker> serial?
<azonenberg_lab> I wish
<azonenberg_lab> if it actually had an external port...
<Harold_parker> aahhh damn :(
<azonenberg_lab> Just dragged my roommate's one out, he left his door open :P
<azonenberg_lab> Now i need to find power
<Harold_parker> heheheh
<azonenberg_lab> hey, its fair... he's gone for the weekend and wont miss it
<azonenberg_lab> and he uses my tools all the time :P
<Harold_parker> hehehe
<Harold_parker> i'm sure he'd be honoured
<Harold_parker> honored
<Harold_parker> lol
<azonenberg_lab> wow, this thing is still on ubuntu 9.04
<azonenberg_lab> i havent used it in so long lol
<azonenberg_lab> its been unplugged for the last few months since i pulled the power supply to test another box
<azonenberg_lab> And never bothered to put it back in
<azonenberg_lab> The thing uses soooo much electricity i dont use it unless i need the horsepower lol
<Harold_parker> haha yeah
<Harold_parker> and they'rre so damn noisy too!
<azonenberg_lab> Actually, this one is quite quiet
<azonenberg_lab> the rest of my rack is several times louder
<azonenberg_lab> The problem with this one is it costs $200ish a month to keep running :P
<azonenberg_lab> 2x 1kW power supplies will do that to you
<Harold_parker> yikes!!
<Harold_parker> yeh i've seriously wondered at the possibility of pulling the case open
<Harold_parker> and ditching the high power psus
<Harold_parker> if its kept cool enough maybe all those fans are a waste of power?
<azonenberg_lab> WIth this box? Not a chance
<Harold_parker> ahh damn
<Harold_parker> whats in it?
<azonenberg_lab> quad core amd (sucky, i want a new mobo with an i7)
<azonenberg_lab> 16gb ddr2
<azonenberg_lab> and four tesla c1060
<azonenberg_lab> Its in a tower case since we couldnt find a rack case that could hold four double-width gpus :P
<Harold_parker> ooooooh
<Harold_parker> sexeeeeeeh
<Harold_parker> how are those tesla's treating you?
<Harold_parker> :D
<azonenberg_lab> I want C2xxx
<Harold_parker> are they what sucks all the juice?
<Harold_parker> yeah
<Harold_parker> srsly
<Harold_parker> :D
<azonenberg_lab> the 1xxx are nice but they dont have any L1 cache
<Harold_parker> ewwww
<Harold_parker> weak
<azonenberg_lab> I have a box in my office thats a 4U
<azonenberg_lab> i7, 12gb ddr3
<Harold_parker> :D
<azonenberg_lab> and 2x gtx 480
<Harold_parker> noice
<azonenberg_lab> Right now its operating at reduced capacity due to a dying PSU (lost a 12V rail or two) but the spare arrives tomorrow
<Harold_parker> :(
<azonenberg_lab> then i have another 4U job at home on the rack that's only 6GB ram, i7, and a geforce 9500 (mostly a file server)
<azonenberg_lab> and two more 2U compute nodes, each with a geforce 9800, core2quad, 8gb ddr2
<azonenberg_lab> Not a bad cluster for a home rack
<Harold_parker> wow
<Harold_parker> fuckin nice man
<Harold_parker> :D
<azonenberg_lab> in fact, when the CS department had an outage recently i offered my advisor's research group accounts on the rack lol
<Harold_parker> what have you been throwing at it?
<Harold_parker> hahaha
<azonenberg_lab> Two or three of the guys were running simulations on it for a while
<Harold_parker> nice
<Harold_parker> awesome
<Harold_parker> were they pleased?
<azonenberg_lab> My boxes had good uptime
<azonenberg_lab> so yeah :P
<Harold_parker> haha noice
<Harold_parker> what kind of sims were they running
<azonenberg_lab> They actually had moved from the department machines to a single server i admin for my advisor earlier
<azonenberg_lab> because the dept boxes were on a flaky raid file server
<azonenberg_lab> That box was then knocked out by a PSU failure
<azonenberg_lab> So while we waited for the spare to arrive i let them use my rack
<Harold_parker> hah nice
<azonenberg_lab> And i'm not sure, i'm not in that research group (data mining)
<azonenberg_lab> the two groups i'm involved in are graphics (summer research assistantship) and security (which i'm doing my thesis work in)
<Harold_parker> oooh cool
<Harold_parker> nice mate :D
<Harold_parker> whats the thesis topic?
<azonenberg_lab> Personally, i got the cluster for an outside consulting job i was doing last year (molecular dynamics modeling)
<Harold_parker> wafer RE ?? >:D >:D >:D
<azonenberg_lab> The guy just got back to me and said he needed more sims done which is why i'm firing up this compute node, which had been gathering dust
<Harold_parker> noice
<azonenberg_lab> I normally keep the file server and one of the 2U jobs up all the time and WoL the others if i need more computing power
<Harold_parker> will they help with the cots?
<Harold_parker> costs
<azonenberg_lab> Yeah
<Harold_parker> aye nice
<azonenberg_lab> and my thesis topic is still a little up in the air as i only entered the phd program three weeks ago :P
<azonenberg_lab> But it will be something related to cpu-level security
<azonenberg_lab> probably at the archiecture level with prototyping and testing of threat models on FPGAs
<azonenberg_lab> Right now RE is purely a hobby
<azonenberg_lab> though in a few years, with a lot of hobby-level RE under my belt plus a dissertation on embedded security, you never know lol
<azonenberg_lab> tip curvature radius is around 1.5 microns i estimate
<Harold_parker> ooooh
<Harold_parker> nice man :D
<Harold_parker> very very nic e:D
<Harold_parker> holy fuck
<Harold_parker> that is TIGHt
<Harold_parker> jesus fuck
<Harold_parker> pro :D
<Harold_parker> did you order that?
<azonenberg_lab> Heck no
<azonenberg_lab> homebrewed
<azonenberg_lab> electrochemical etching of 406um tungsten wire in 20% KOH at 3VDC
<Harold_parker> :D
<azonenberg_lab> I need to refine the process, the next few i did werent quite as sharp (maybe 2-3um radius)
<Harold_parker> doooood
<Harold_parker> this is super pro!
<azonenberg_lab> Gonna pop some under the SEM soon to see how they look up close
<azonenberg_lab> and get more accurate measurements
<Harold_parker> :D
<Harold_parker> how did you refine the tip to that sharp point :O
<Harold_parker> ?
<azonenberg_lab> Woo, the tesla box is now online (just wanted to fsck after a long time offline)
<azonenberg_lab> Welcome to GLaDOS, motivating coders with premium quality cake since 1986.
<azonenberg_lab> This system is equipped with 4x nVidia Tesla C1060, a 3.0 GHz quad-core AMD
<azonenberg_lab> processor (Phenom II x4 940) and 16GB ram.
<azonenberg_lab>   3.73 teraflops peak performance (single-precision).
<Harold_parker> hehehe
<Harold_parker> noice :)
<azonenberg_lab> root@glados:~# lspci | grep Tesla | wc -l
<azonenberg_lab> 4
<azonenberg_lab> And they're all there, i've had issues with loose cards causing some of them to not show up
<Harold_parker> hahahahaa
<Harold_parker> <-- jelly
<Harold_parker> oh dang
<azonenberg_lab> Actually its not loose *cards*
<azonenberg_lab> its the pcie power connectors
<Harold_parker> ?
<Harold_parker> ahhh
<azonenberg_lab> anyway so the tip was electrolytically etched
<Harold_parker> so the tip is define by anode position?
<Harold_parker> fuck i wish i knew my chemistry :(
<azonenberg_lab> The tip is the anode, and the mechanism for sharpening is a mix of bubbles being dragged along the sides by surface tension
<azonenberg_lab> and etch products falling down
<Harold_parker> ooooh
<Harold_parker> awesome man :D
<Harold_parker> thats fuckin awesome
<azonenberg_lab> You saw my lift-off patterning test i assume?
<Harold_parker> probably, i've been away for 1.5 weeks
<Harold_parker> so if it was before then??
<Harold_parker> i remember some tests just before i went away
<Harold_parker> and you were mapping edge characteristics
<azonenberg_lab> This was after baking, it looked better before
<azonenberg_lab> hardmask was too thick and it cracked
<Harold_parker> ooooooh
<azonenberg_lab> after the etch it disintegrated
<Harold_parker> still, looks nice man
<Harold_parker> whats the scale?
<azonenberg_lab> lines in the font are around 20um
<azonenberg_lab> I didnt have my calibrated camera set up for these shots
<azonenberg_lab> just my point&shoot on the eyepiece
<Harold_parker> :O
<Harold_parker> dude this is awesome
<Harold_parker> so that fullstop would be like...4um
<Harold_parker> ?
<azonenberg_lab> The lines are 20um wide
<azonenberg_lab> I was using a large process size for debugging
<Harold_parker> nice
<azonenberg_lab> i can hit 5um lines in photoresist on a good day but the rest of the process isnt able to keep up
<Harold_parker> ahhh yes
<Harold_parker> i see
<azonenberg_lab> (yet)
<azonenberg_lab> TODO for the weekend lol
<Harold_parker> :D
<Harold_parker> excellent
<azonenberg_lab> I want to get a pattern of some sort, even if on a giant 50um process, etched in <100> Si with KOH and Ta2O5 hardmask
<azonenberg_lab> Once i get adequate yields in that, i can start shrinking
<Harold_parker> yeah nice
<Harold_parker> by yields you mean resolution?
<azonenberg_lab> no, i mean things not chipping off in the etch and giving me blank dies :P
<Harold_parker> ahh yep
<Harold_parker> what do you think is causing that?
<azonenberg_lab> In that one? Hardmask was too thick
<azonenberg_lab> The problem is that the hardmask is spin coated over photoresist (lift off process) in an ethanol solution
<azonenberg_lab> my photoresist is slightly soluble in ethanol
<azonenberg_lab> as you can probably imagine that doesnt end well :P
<azonenberg_lab> Workaround is to drop the hardmask on and immediately spin up really fast
<azonenberg_lab> but that reduces consistency and its easy to get too thin or thick a layer
<azonenberg_lab> I have ideas but havent experimented with them yet
<Harold_parker> ahhh yep
<Harold_parker> i getcha
<Harold_parker> nice
<Harold_parker> i'll be eager to see what you find
<CIA-67> homecmos r91 | trunk/lithography-tests/labnotes/azonenberg_labnotes.txt | Today's lab notes.
<azonenberg_lab> Hmm, this should be fun
<azonenberg_lab> going to try soldering one of these probes to a copper wire
<azonenberg_lab> and using it
<Harold_parker> nice!!
<Harold_parker> how's it performing?
<Harold_parker> using on decapped?
<azonenberg_lab> Going to, yes
<azonenberg_lab> i have a 12f683 i pwned a while ago with uv
<azonenberg_lab> gonna pop it in a breadboard and see how it goes
<azonenberg_lab> just have to get firmware on it
<azonenberg_lab> i'll just be hitting bond pads as thats what i intended thse probes for
<azonenberg_lab> but if that works i'll go to town :P
<Harold_parker> :D
<Harold_parker> yeah man
<Harold_parker> fuckin nice!!
<azonenberg> fires up vmware box with mplab on it
<azonenberg> gaah, i have too many vms
<azonenberg> cant remember which one it is :p
<azonenberg> Here we go *looks at blinking light*
<Harold_parker> heheheh
<azonenberg> lets make this a bit slower so i can probe it with something slow
<azonenberg> lacks a working DSO atm
<azonenberg> on the to-get list
<azonenberg_lab> Setting it up... here goes
<azonenberg_lab> aww, bent the tip
<azonenberg_lab> Even bent, its more than sharp enough to hit the target though
<azonenberg> Pics coming soon
<azonenberg> I dont have a proper illuminator so i just used the lamp
<azonenberg> There were some shadowing issues but it worked decently well
<azonenberg> here's a close up of the chuck area with the breadboard on it http://colossus.cs.rpi.edu/~azonenberg/images/homecmos/2011-06-24/S7300936.JPG
<Harold_parker> awwwwwwwa awww awww awwwwwwww yeah :D
<Harold_parker> bwhahahaha
<Harold_parker> nice man
<Harold_parker> that looks
<Harold_parker> fuckin awesome :D
<Harold_parker> :D
<Harold_parker> noice
<azonenberg> Bad lighting but you can see i'm htiting the pad
<Harold_parker> :D
<Harold_parker> oh yeah
<Harold_parker> bwhahaha
<Harold_parker> fuckin nice mate!!
<Harold_parker> this is so cool
<azonenberg> this is the most my scope can hit atm (stereozoom 4, 3x objective * 20x eyepiece = 60x)
<azonenberg> i'll be doubling it with a better objective shortly
<azonenberg> But since the intended purpose of the unit is wafer test and not RE i should be fine
<azonenberg> When i have the budget for an FS60, of course, all bets are off :P
<Harold_parker> :D
<azonenberg> *drools at thought of 100x LWD objective*
<Harold_parker> nice
<azonenberg> And its not like i need to probe the 683 anyway lol
<Harold_parker> i suppose you can attain soooome digital zooming with enough res in the photos?
<azonenberg> its easy to pwn with uv
<Harold_parker> 683?
<Harold_parker> ahh nice
<Harold_parker> the pic?
<Harold_parker> awesome
<azonenberg> Yeah, i did it a few months ago on the other die from this same batch
<azonenberg> Note how overkill this needle is for this magnification though lol
<azonenberg> i need more zoom to even see the tip :p
<Harold_parker> ahhhh yeh serious
<Harold_parker> for interior proving it might be good though?
<Harold_parker> *probing
<azonenberg> The intention is wafer test
<Harold_parker> oh yeah!!
<Harold_parker> :d
<azonenberg> hitting bond pads for the customer's new gadget to see if it works
<azonenberg> before wasting time and $$ packaging them up
<azonenberg> And i've hit targets of the same size on the 683 so its definitely adequate
<Harold_parker> aye yep
<azonenberg> Conveniently that also means it's good enough for testing my devices too ;)
<Harold_parker> ahhh nice
<Harold_parker> ahaha yes
<Harold_parker> indeed :D
<Harold_parker> quite so!!
<azonenberg> Best part? Client paid for it so the whole rig cost me nothing
<Harold_parker> bwhahahahaha
<Harold_parker> now that is gold
<Harold_parker> what is the product/
<Harold_parker> ?
<azonenberg> NDA, sorry
<Harold_parker> hah nice
<Harold_parker> ;)
<Harold_parker> how much was that micropositioner?
<azonenberg> 125 a pop
<azonenberg> on ebay
<Harold_parker> nice!
<azonenberg> Dirt cheap as they go, i wasnt expecting a S926 or similar lol
<Harold_parker> heheh
<azonenberg> its rated for 5um targets so my tips are already several times more precise than it needs
<Harold_parker> awesome
<azonenberg> Doesnt stop me from wanting to do better of course
<Harold_parker> ;)
<berndj> i didn't know that the DMCA applied in singapore
<bart416> berndj, it doesn't as far as I know
<berndj> which is why i don't get how B0101 was getting DMCA takedown notices on his singapore host?
<bart416> oh they try
<bart416> They try hard
<bart416> Mind you, if you live in the SU they'll still try to get to you
<bart416> I mean I live in Belgium, and I get DMCA notices for a server in Sweden...
<bart416> They don't even bother to check the country you live in
<berndj> azonenberg, sorry to keep harping on about that uni STM project, but IIRC they (he?) made their probe by just pulling a lamp filament until it broke; with near certainty the break site would have a 1-atom tip *somewhere*
<bart416> They just send the DMCA notices and threaten to sue
<berndj> so ray gordon of them!
<bart416> They usually shut up after you tell them you live outside the US
<bart416> well for a week at least
<bart416> Now I have a mail filter that redirects all mails with DMCA or the common takedown template to /dev/null
<bart416> Saves me time and worries
<berndj> you should get them on SORBS
<bart416> lol
<berndj> mindboggling that he got takedown notice on his own lab notes!
<bart416> oh fun
<bart416> At least in our case it's somewhat logical that they try to push DMCA takedown notices for DCC servers >_>
<berndj> i thought sending fake takedown notices was a pretty serious offence
<bart416> What was in the lab notes?
<bart416> linky to them please
<berndj> i dunno what B0101 is up to
<bart416> Wouldn't be amazed if some publisher tried it
<bart416> If there's a solution to one of their exercises in it
<bart416> They did the same thing with students making answer databases in the US
<berndj> it's a good reason to officially register your copyrights - then statutory (rather than just actual) damages kick in
<berndj> that rings a bell... schaum's outline series maybe?
<bart416> Nah, not schaum's
<bart416> Schaum's doesn't seem to give a fuck
<berndj> hmm. but i vaguely recall something about schaum's too
<bart416> We published all the solutions to every single question in schaum's outline of signals and systems on the internet somewhere
<bart416> We never got a single response on it
<bart416> In fact most people don't even bother to check it (even those that need it)
<berndj> maybe they have sane / ethical lawyers and/or same for execs
<berndj> this whole patent / copyright trolling this is so dirty
<berndj> i'm really glad i don't live in a very litigous society
<bart416> can't wait to get a DMCA takedown notice for http://ieatbirds.info/mechanica2.pdf
<berndj> i keep telling azonenberg he should come do his work in .za then he can just pour used HF et al straight down the sink :)
<bart416> That's more DMCA worthy since that are solved exercises
<bart416> lol
<bart416> I should really get around to scanning in all my old notes and exercises and putting them online
<bart416> berndj, who would want to live in .za :p
<berndj> heh.  meh, i like it here
<bart416> Dunno, my current plan is to work for about 30-40 years and then move to some desolated place in vietnam or something like that
<berndj> if you believe in those climate models i saw a map yesterday that suggested you'd want to invest in uruguay
<bart416> My problem with Africa is the average mentality of the people who live there
<berndj> yeah, african states have this predatory tendency
<bart416> More like lazy
<bart416> Pretty much all the Africans who move here seem to care about two things: Living of social security and screwing 5 women at once
<bart416> And for every single one of them that isn't like that, there are 50 who are
<berndj> haha, where is this "here" btw?
<bart416> Belgium
<bart416> They're really fucking up our social security system the way they're acting
<berndj> we get some of that too - ppl coming here from all over the rest of africa, but we seem to attract mostly the industrious subset
<bart416> Heh, for me the contrast is even bigger
<berndj> which breeds envy, and sporadically erupts into a variation of kristallnacht
<bart416> I live in a small village where over half the population is made up out of asian immigrants...
<berndj> anyway labour is fairly cheap here
<bart416> Most labour got shipped off to east europe, heh
<berndj> so when we dig a new cable route we do it with a line of 50 men, not a single backhoe in sight
<bart416> Heh
<berndj> hmm, electronics + cheap labour: i wonder if anyone's ever tried building a human computer
<berndj> like a relay computer, but using humans as the switching elements
<bart416> Lets try it!
<bart416> Just duct tape them to a wall
<bart416> and if they make mistakes they don't get food for a day
<berndj> ok, just get 2000 people on a football field, we can build a 4004
<berndj> would you treat a transistor like that???
<berndj> there are now more transistors than ants
<berndj> any i gtg buy some tomatoes before the shop closes
<bart416> <berndj> would you treat a transistor like that??? <-- lazy people who don't contribute to society are less than ants for me
