| jrayhawk | it seems like it wouldn't be even slightly difficult for a major nation to swamp the tor network with nodes in order to map out hosts and users | 00:54 |
|---|---|---|
| Utopiah | I think you'd much more than the majority of nodes to isolate users, sth prohibitive like >99% , also if governments are using them too, I doubt they'd want to disable it | 00:58 |
| jrayhawk | That'd be true if what you were mapping only occured over one route; most of the things a major government would want to attack involve persistent identities that would be traversing multiple routes over time. | 01:01 |
| Utopiah | but I think the point is that routing isn't predictable | 01:03 |
| jrayhawk | Yes. That's the point. | 01:03 |
| jrayhawk | If a government took over 50% of the nodes under a fair distribution, it'd have a 50% chance of being the first hop or last hop. If it's able to attach an identity to traffic traveling through it, then it can build up a record of routes that idenitity has gone through and find statistical outliers. | 01:06 |
| Utopiah | I think end-to-end correlation is possible but one can also pick the preferred exit nodes | 01:08 |
| Utopiah | plus ideally I think you also don't "exit" | 01:08 |
| jrayhawk | Yes, thus 'last hop' | 01:08 |
| jrayhawk | Anyway, the freenet model is a lot less broken than the tor model, but it's less convenient. | 01:10 |
| Utopiah | if you have suggestion for each project they are present here on freenode :) | 01:14 |
| * Utopiah is wondering where he could get Physica A, Vol. 389 beside Elsevier fence | 01:15 | |
| jrayhawk | really it's more a suggestion that all these illegal-but-highly-public .onion sites should really be less highly public | 01:20 |
| jrayhawk | Or alternatively arrange themselves to de-incentivize the use of perisistent identity or making timing attacks far more difficult. | 01:22 |
| jrayhawk | anonymous SSL is great so long as you're using an extremely noisy protocol, but HTTP and IRC are not noisy and the end result of user activity over them usually has timestamps. | 01:23 |
| fenn | i thought freenet was mostly about making sure that important info remained available | 02:06 |
| fenn | easy enough to increase randomness of the data by compressing before encrypting | 02:08 |
| jrayhawk | sometimes i wonder if trustwebs would be more popular if all the OpenPGP implementations weren't wretchedly unusable | 02:22 |
| fenn | for most applications they don't need to be cryptographically secure, but still nobody uses the concept | 02:24 |
| fenn | so i dont think pgp has anything to do with it | 02:24 |

| CryptoQuick | why does it always have to be nanotechnology, couldn't some of us work towards something on a larger scale? | 16:59 |

| ybit | true, as in mechanically controlled nanotech | 17:09 |
| kanzure | you should consider reading those links | 17:09 |
| QuantumG | I don't even see it starting.. it's just Merkle and Freitas in a circle jerk right now. | 17:09 |
| kanzure | QuantumG: well, plus their russian colleagues | 17:09 |
| ybit | so it seems | 17:10 |
| QuantumG | yeah.. writing lots of paper | 17:10 |
| kanzure | doin' simulations | 17:10 |
| kanzure | plus zyvex makin' stuff | 17:10 |
| ybit | i talked with some, guy, berhane <lastname> who collaborated with those guys for this phd thesis | 17:10 |
| QuantumG | yep, simulating stuff that they don't know how to build | 17:10 |
| kanzure | QuantumG: actually, they generally do know how to build it | 17:10 |
| ybit | ab-initio something something something | 17:10 |
| kanzure | ab initio chemistry? | 17:10 |
| ybit | i forget the name of the paper | 17:10 |
| QuantumG | talking about how they might figure out how to build it if they were to actually start doing some experiments at some point. | 17:10 |
| kanzure | QuantumG: in general, they know what to do | 17:11 |
| ybit | QuantumG: er.. | 17:11 |
| kanzure | but they suffer from "we need more money syndrome" | 17:11 |
| ybit | i've also spoken to phillip moriarty | 17:11 |
| QuantumG | pfft.. they *think* they know what to do | 17:11 |
| ybit | he's doing some actual work on this | 17:11 |
| ybit | though he apparently doesn't think molecular manufacturing will ever happen | 17:11 |
| kanzure | ribosomes are fake? | 17:11 |

| QuantumG | theoretical plans rarely dictate reality.. tinkering has made more things than deep thought ever will. | 17:12 |
| kanzure | QuantumG: i think you're just trolling | 17:12 |
| kanzure | and i also suspect you haven't looked at the literature | 17:12 |
| kanzure | because i clearly do remember experiments.. | 17:12 |
| ybit | Question: So you are still a skeptic of the concept of molecular manufacturing? | 17:12 |
| ybit | Answer: I am a skeptic. I believe that the concept of molecular manufacturing - of creating macroscopic objects atom by atom for any material, is flawed. I do not believe that this technique can be scaled-up to manufacture macrosized objects for arbitrary materials. | 17:12 |
| ybit | Who knows, maybe some day though | 17:13 |
| kanzure | ybit: of arbitrary materials? | 17:13 |
| kanzure | most of freitas' stuff is about diamondoid mechanosynthesis | 17:13 |
| kanzure | i.e., carbon | 17:13 |
| QuantumG | kanzure: I'm not trolling.. and I've read everything they've written. | 17:13 |
| kanzure | QuantumG: ok, then you know about their physical experiments | 17:13 |
| ybit | "I’ve never been able to see why it is then claimed that these schemes are extendable to all other materials (or practically all elements in the periodic table)" | 17:14 |
| kanzure | and you're mis-representing them because you feel lethargic or lied to? | 17:14 |
| ybit | i've yet to read the debate he had with phoenix | 17:14 |
| kanzure | ybit: carbon not enough for you right now? | 17:14 |
| QuantumG | which physical experiments would these be? | 17:14 |
| kanzure | QuantumG: mostly the ones with AFMs and UHVs | 17:14 |
| ybit | i keep swaying back and forth between synbio and mol.nanotech | 17:14 |
| kanzure | swaying? | 17:15 |
| ybit | yeah | 17:15 |
| kanzure | are you trying to figure out which one to be excited about? | 17:15 |
| ybit | not sure which to pursue, i have limited time and limited gray goo | 17:15 |
| kanzure | how about both | 17:15 |
| ybit | limited gray goo problem | 17:16 |
| kanzure | how about you fix that | 17:16 |

| fenn | so it turns out modafinil actually does make you rabidly do stuff | 17:21 |
| fenn | it just probably isnt the thing you decided to do beforehand | 17:21 |
| QuantumG | heh | 17:21 |
| ybit | sounds more like my exp with ritalin | 17:21 |
| QuantumG | I thought ritalin was the opposite | 17:21 |
| fenn | also it seems to last at least a day afterward | 17:21 |
| ybit | did you have problems sleeping? | 17:22 |
| fenn | ritalin is prescribed for adhd because it makes you focus | 17:22 |
| ybit | bullshit | 17:22 |

| fenn | hum i guess i did try piracetam a long time ago, but since nobody knew how it worked it didn't really help me understand what words like 'serotonin' or 'dopamine' actually meant | 17:29 |
| kanzure | "it works by increasing dopamine in the brain!" is a bullshit explanation for just about any drug imaginable | 17:29 |
| kanzure | oh even better is when they say "increases dopamine levels" | 17:30 |
| kanzure | gotta add 'levels' | 17:30 |
| fenn | i thought this had a pretty good explanation of how it works http://en.wikipedia.org/wiki/Amisulpride | 17:31 |
| kanzure | oh shit, dissociation constants | 17:31 |
| kanzure | things just got technical | 17:31 |
| fenn | "doses in the 50 to 200 mg range preferentially block inhibitory pre-synaptic autoreceptors. This results in a facilitation of dopamine activity" | 17:31 |
| kanzure | for adderall it's much less specific | 17:31 |
| kanzure | yeah, that's way more specific than what i usually dig up | 17:32 |
| fenn | "[ritalin] increases the levels of dopamine and norepinephrine in the brain through reuptake inhibition of the monoamine transporters. " | 17:32 |
| fenn | i guess that means its just floating around in the synaptic cleft | 17:33 |
| kanzure | well iirc that means it's more like a | 17:33 |
| kanzure | what is the name for a molecule that modifies the function of a primary molecule? | 17:34 |
| fenn | narcolepsy! | 17:34 |
| fenn | they must pump those people so full of stuff they can't think straight | 17:34 |
| kanzure | for instance, in many cases hydrogen is used as a way to change the conformational structure of a protein | 17:34 |
| fenn | uh. hydrogen? | 17:34 |
| fenn | you mean a functional group? | 17:34 |
| fenn | like methylation or phosphorylation | 17:34 |
| kanzure | no something more vague | 17:34 |
| kanzure | it doesn't matter. i'll think of the word eventually. | 17:35 |
| fenn | my 10-second take on it is that ritalin just gets jammed in the reuptake transporters and thus you need less dopamine to trigger the receiving neuron | 17:35 |
| kanzure | "tudies have shown that in select regions, amphetamine increases the concentrations of dopamine in the synaptic cleft, thereby heightening the response of the post-synaptic neuron" | 17:36 |
| kanzure | that's not an explanation.. that's a correlation | 17:36 |
| kanzure | (the quote, not your 10-second take) | 17:37 |
| kanzure | but yes that's generally the consensus fenn | 17:37 |
| -!- He||eshin is now known as Helleshiny | 17:37 | |
| kanzure | "One theory emphasizes amphetamine’s actions on the vesicular level, increasing concentrations of dopamine in the cytosol of the pre-synaptic neuron.[24][27] The other focuses on the role of the dopamine transporter DAT, and proposes that amphetamine may interact with DAT to induce reverse transport of dopamine from the presynaptic neuron into the synaptic cleft." | 17:37 |
| fenn | can't they just make DAT knockout mice and see if it does anything? | 17:38 |
| kanzure | WHAT? DO ACTUAL WORK? | 17:38 |
| fenn | well it's not like they're going to take their own medicine | 17:39 |
| kanzure | membrane proteins like DAT are easy to study once you have your mice engineered (microdialysis/typical neurophysiology) | 17:40 |
| fenn | lulz "[ritalin's] pharmacological effect on the central nervous system is almost identical to that of cocaine. Studies have shown that the two drugs are nearly indistinguishable when administered intravenously to cocaine addicts." | 17:42 |
| fenn | i wonder how many suburban parents know that | 17:42 |
| fenn | "Professor John Harris, an expert in bioethics has said that it would be unethical to stop healthy people taking the drug. He also argues that it would be "not rational" (i.e. irrational) and against human enhancement to not use the drug to improve people's cognitive abilities." | 17:44 |
| kanzure | i wonder what that irrationality argument is | 17:45 |
| QuantumG | or antirational | 17:45 |
| fenn | it's sort of like the anti-nuclear-reactor argument.. there's nothing wrong with the nuclear reactor itself, it's what you MIGHT do with the ingredients | 17:46 |
| QuantumG | as John Gilmore once said.. it's not drugs that are illegal, it's altering your mind. | 17:46 |
| fenn | heh | 17:47 |
| fenn | yes we need a few constitutional amendements guaranteeing freedom of thought and freedom of self-modification | 17:47 |
| fenn | considering obama is the most liberal president in the last 50 years i think we have a ways to go | 17:48 |
| fenn | (i voted for kucinich) | 17:49 |
| kanzure | i voted for morbo | 17:49 |
| jebba | gary johnson! :) | 18:00 |
| kanzure | jack johnson vs. john jackson | 18:01 |
| fenn | jebba: drug reform because it's too expensive to arrest people achieves the desired result for the wrong reason | 18:02 |
| jebba | fenn, there's also, uh, convincing people to accept the change... The "you have a right to your body" will leave us with a drug war for another 50 years. "Drug war is total failure" convinces more people. | 18:05 |
| kanzure | what is your role with gary | 18:06 |
| -!- eridu [~eridu@gateway/tor-sasl/eridu] has joined ##hplusroadmap | 18:06 | |
| jebba | No role other than supporter. Though i talk/email with them a bit. He called me for a 3 minute conversation recently. | 18:07 |
| jebba | Plus i saw him in Denver when he was here month+ ago and I went out to NH for the announcement. | 18:07 |
| jebba | http://desktop.alephobjects.com/~jebba/gj/announcement/ | 18:07 |
| fenn | what's the point of a dual PD/BY-SA license? | 18:09 |
| fenn | can't whoever just take the PD thing and slap whatever license (like BY-SA) on it? | 18:09 |
| jebba | fenn: Well, just in case anyone wanted it under that, they can just take it as BY-SA. There is a bit of grey area about putting things in PD, so I just did both. | 18:10 |
| jebba | btw, the robot factory is coming alive! http://www.alephobjects.com/photos/hq/ | 18:10 |
| fenn | white .. everything | 18:10 |
| fenn | looks like you won't be running out of stepper drivers for a while | 18:12 |
| jebba | haha | 18:15 |
| jebba | Our goal is 16 prusas this quarter.... (which ends RSN!) | 18:15 |
| fenn | how many machines do you have printing currently? | 18:16 |
| fenn | i mean functional | 18:16 |
| jebba | Here we have 4 prusas, we have 1 prusa out at someone's house, a cupcake, a ToM (that hasnt printed much as the guy who had it just sat on it), a shapercube that is mostly retired, a huxley. | 18:17 |
| jebba | We really only use the prusas now and are working on more of them. | 18:18 |
| fenn | yeah prusa is a good design | 18:19 |
| jebba | the huxleys we had didnt work well (only got one of them to ever print) and the shapercube (version 1) was hard to get going. The makerbots were nice. I used the cupcake quite a bit for awhile. But now all focus is on prusas. | 18:20 |
| fenn | you use the arcol derived nozzle? | 18:20 |
| jebba | On the latest one we have a pure budaschnozzle (arcol derivative). We have a hybrid on another. And parts for 15 more budaschnozzles: http://www.alephobjects.com/photos/hotends/budaschnozzle/0.3/ | 18:21 |
| jebba | http://www.alephobjects.com/budaschnozzle/ code/schematics/etc/GPLv3 | 18:22 |
| jebba | Arcol's hotend was CC-non-commercial, non-derivative so I had an engineer redo it based on the physical object and draw up fresh files. | 18:22 |
| jebba | Though he's done a few mods to it as well (is shorter for one, slightly increasing Z, for example) | 18:22 |
| fenn | you should put up a link to the nozzle on your page, maybe even an image | 18:23 |
| jebba | ya, will re-vamp that whole thing ;) | 18:24 |
| jebba | we'll have a shop running in august. | 18:24 |
| fenn | i like the "made in usa" wiring :) | 18:30 |
| fenn | http://www.alephobjects.com/photos/hotends/budaschnozzle/0.3/parts/DSC_0540-1024.html | 18:31 |
| fenn | also, the actual nozzle is a thing of beauty http://www.alephobjects.com/photos/hotends/budaschnozzle/0.3/parts/DSC_0536-1024.html | 18:31 |
| fenn | cool brain visualization http://www.youtube.com/watch?v=6YFG5OnDp-Y | 18:34 |
| fenn | hm. all the google image search results for diffusion tensor imaging are of brains | 18:45 |

| kanzure | heh http://lulzsecurity.com/releases/ | 18:50 |
| ybit | synbio products of relevance to rocketry, go | 18:50 |
| ybit | i can't think of any atm | 18:51 |
| kanzure | how about you go ask john cumbers | 18:51 |
| kanzure | it's his fucking job | 18:51 |
| kanzure | oh shit http://lulzsecurity.com/releases/Sony_Pictures_International_DELBOCA_USERS.txt | 18:52 |
| ybit | i watched some vids from the synbio conf at nasa ames | 18:53 |
| ybit | didn't see much related to rocketry | 18:53 |
| fenn | bio != rocketry | 18:53 |
| fenn | except for bombardier beetles | 18:53 |
| QuantumG | ybit: make a bug that can purify h2o2 | 18:54 |
| fenn | kanzure: so that upload trick is pretty common cracking technique eh | 18:56 |
| kanzure | fenn: which one? | 18:56 |
| kanzure | the lulzsec links are about a recent sql injection attack on sony | 18:57 |
| ybit | why doesn't the wikipedia article on bioinorganic chemistry mention other aspects like deposition of silica and other minerals to make structures? :\ | 18:57 |
| fenn | yeah, there was some kind of photo upload page they exploited | 18:57 |
| kanzure | sql injection is pretty common.. any time i see numbers in a url i try a few possible injections | 18:57 |
| kanzure | even better when it's something so obviously crackable | 18:57 |
| kanzure | imageviewer.php?file=../images/1.jpg | 18:58 |
| fenn | i guess i dont understand what's special about this url http://www.sonypictures.com/homevideo/ghostbusters/photoupload/view.php?id=12838 | 18:58 |
| kanzure | is that it? | 18:58 |
| fenn | "this is its SQLi hole;" | 18:59 |
| kanzure | "the page you requested was not found" | 18:59 |
| kanzure | looks like sony took it down | 18:59 |
| kanzure | yeah, so think of how they are getting the data from the db | 18:59 |
| kanzure | SELECT (whatever) FROM photos WHERE id='$id' | 18:59 |
| kanzure | id=12838 | 18:59 |
| kanzure | id=12838' UNION SELECT (username, password) FROM users WHERE 1='1 | 19:00 |
| kanzure | see pm | 19:01 |
| kanzure | so yeah | 19:03 |
| kanzure | that's the basic structure of an sql injection attack | 19:03 |
| kanzure | but that's not what i was using the other day. | 19:03 |
| kanzure | http://www.justanotherhacker.com/2011/05/htaccess-based-attacks.html | 19:04 |
| kanzure | ah cool a tutorial now :P http://www.justanotherhacker.com/projects/htshells/tutorial.html | 19:05 |
