| Alcyius | I just slept through wednesday | 00:17 |
| FourFire | Hey regarding a book with enough information to reconstruct modern technological civilization with few surviving individuals, I think that would involve a rather large research project about tech trees, and I am somewhat doubtful that all such knowledge currently exists digitially anyway | 00:37 |
| FourFire | stuff like > How to turn the kind of rock that looks like [this] into RAM | 00:37 |
| FourFire | Greetings aurellem ! | 00:46 |
| Alcyius | That seems like it'd be a massive project | 00:46 |
| Alcyius | Isn't there a library of forever project trying to do that though? | 00:46 |

| streety | FourFire: as quickly as possible get to microscopes so you can write the last 100 years of technological development really small | 04:02 |
| streety | testing some of those protocols could be really interesting | 04:03 |
| FourFire | streety, sure. | 04:03 |
| FourFire | or some form of electronic media which is easy to build an interface for | 04:03 |
| FourFire | you can fit lot of text even just into 1GB | 04:04 |
| streety | I'm not sure there is any electronic media with the same robustness, might be wrong though | 04:04 |
| FourFire | streety, well you could intergrate, say redundant thin film memory into the structure of the book in question | 04:05 |
| FourFire | or maybe even make the cover an e-reader | 04:05 |
| ebowden | FourFire, streety, does this channel get trolls? | 04:07 |
| streety | occasionally some seriously off topic content but I don't remember any ongoing issues with trolls | 04:08 |
| -!- nickjohnson [sid789@gateway/web/irccloud.com/x-drwniymebibmschk] has quit [Ping timeout: 240 seconds] | 04:09 | |
| ebowden | I seem to recall some anti transhumanist people. | 04:09 |
| streety | thin film memory could work, potentially both electronically and optically readable? | 04:09 |
| abowden | I think there are some really good, dense new optical tapes about | 04:10 |
| archels | I will never grasp the point of these "reconstruct all civilisation from scratch" books/efforts | 04:10 |
| abowden | what are you trying to make? an archive of all humanities works? | 04:10 |
| ebowden | That's not how you spell it. | 04:11 |

| streety | archels: development tends not to be a linear process, or even a unidirectional process. Securing a record of humanities greatest technological achievements may help speed the recovery from a technological reversal. Prevent technology being lost forever. | 04:18 |
| streety | Also, in learning about what got us to where we are you can develop a deeper understanding of the technology enabling further discovery | 04:19 |
| abowden | one data storage method I know works well as far as longevity and data density goes is quartz glass, if you want to store more than can reasonably store on microfils, hardrives etc | 04:23 |
| abowden | something to keep in mind in your design, in preparation for whenever such technology becomes available to the consumer | 04:24 |

| -!- nickjohnson [sid789@gateway/web/irccloud.com/x-motlwbefqcvtcapy] has joined ##hplusroadmap | 04:26 | |
| archels | streety: it would be nice if the development of deeper understanding were driven by a future technological goal rather than just documenting the past | 04:27 |
| archels | also the technological reversal argument is a little silly, because if all our technology and/or knowledge is destroyed then probably so will these guides | 04:27 |
| ebowden | Aren't they trying to figure out a way to make information such as that more stable in storage? | 04:30 |
| abowden | archels why does every last scrap of technology have to be destroyed for such a guide/archive to be valuable? | 04:31 |
| -!- proofoflogic [sid65184@gateway/web/irccloud.com/x-vijzerlrxhjiuhnk] has joined ##hplusroadmap | 04:33 | |
| abowden | I don´t get it. | 04:34 |
| archels | yes, a great deal would have to be destroyed before such a guide could be valuable | 04:36 |

| abowden | if even 20% was gone, it would still be valuable to have a means of getting it back | 04:39 |
| abowden | so you don´t have to build it all again from the ground up | 04:39 |
| -!- Viper168 [~Viper@unaffiliated/viper168] has quit [Ping timeout: 246 seconds] | 04:39 | |
| abowden | you can just search the database to find out what yo uneed to know | 04:40 |
| archels | it's already pretty well documented how to rebuild this 20% from whatever remains | 04:40 |
| archels | what are you going to do, describe how to build every last human artefact from raw natural resources? what's the point spending all the time and energy? | 04:41 |
| abowden | documented where? | 04:41 |
| -!- CheckDavid [uid14990@gateway/web/irccloud.com/x-xjognapsetrdyidn] has joined ##hplusroadmap | 04:41 | |
| archels | there's books on how to make stuff. lots of books | 04:41 |
| abowden | is it all in one place? | 04:41 |
| archels | planet Earth? | 04:42 |
| abowden | streety, am I correct in presuming this a doomsday provision? | 04:42 |
| streety | I'm not sure what FourFire had in mind but I don't think it needs to assume a doomsday event | 04:44 |
| archels | it's probably more decentralised now than it would be if it were all wrapped up in a single guide | 04:44 |
| abowden | centralising it would be a good thing, ince it would make it a lot easier to access. | 04:45 |

| FourFire | <archels> I will never grasp the point of these "reconstruct all civilisation from scratch" books/efforts | 06:27 |
| FourFire | Not all of civilizatio, just whatever very useful technology suddenly gets lost postapocalypse, if, say 90% of humanity dies out suddenly, you're going to be missing parts of the specialist toolchan | 06:28 |
| FourFire | toolchain* | 06:28 |
| FourFire | abowden, which biology channel is this, do they do/discuss anything bioinformatics related? | 06:30 |
| archels | like all the telephone sanitisers and hairdressers suddenly dying out at once, right | 06:31 |
| FourFire | archels, you just need to kill off enough people for the survivors to have a hard time locating specific knowledge/records to rebuild/keep running advanced technology | 06:32 |
| FourFire | what is the us factor for, say, samsung, or intel, or NASA for that matter? | 06:32 |
| FourFire | archels, my propsition is to build specialized hardened structures which could survive most apocalyptic events which would kill most humans (probably underground bunkers) | 06:33 |
| FourFire | archels, do you consider telephone sanitization and/or hairdressing to be "very useful technologies" ? | 06:38 |

| sandeepkr | https://courses.cit.cornell.edu/ee476/FinalProjects/s2006/hmm32_pjw32/#SHDesign | 06:50 |

| FourFire | sandeepkr, well with the galvanic response, a temperature change would lead to readings which were all skewed to some extent during the period of time following the temperatue change. | 07:18 |
| FourFire | how do you account for this | 07:19 |
| FourFire | because the readings will still contain the data you want, | 07:19 |
| FourFire | you just have to be able to interpret a higher average and median of reads for a given period of time as a shift in the zero point | 07:20 |
| sandeepkr | FourFire, do you think it will be problem in a living room? | 07:23 |
| sandeepkr | the temp change | 07:23 |
| FourFire | sandeepkr, temperature difference is only one example of such a drift | 07:24 |
| FourFire | cause* | 07:24 |
| FourFire | you'll want to be reading some of the other possible causes but not all of them, I suppose | 07:24 |
| sandeepkr | FourFire,right.that can be be done. | 07:25 |
| sandeepkr | i can easily attach other sensors for that. | 07:25 |
| sandeepkr | but right now, im just curious about taking some reading. | 07:26 |

| nmz787_i | howdy | 10:12 |
| kanzure | greetings fleshlings | 10:12 |
| nmz787_i | I am trying to open a electrical CAD .brd file... and convert it to kicad... so far I've run the file through TRId and scanned it for file signatures. I used two different sig databases, and one says 100% chance that it is a dBase database file... the other says 50% that file, 50% a MapInfo file | 10:15 |
| nmz787_i | I haven't been able to get anywhere with linux tools like dbf2csv (or is it dbfdump?) or the dbfread python library | 10:16 |
| kanzure | try using the `file` tool | 10:16 |
| kanzure | also when in doubt just look at the raw data: hexdump -C myfile.blah | 10:17 |
| nmz787_i | not sure what to do now aside from some bioinformatics type approaches... look for repeats (maybe headers in sections of the file) | 10:17 |
| kanzure | or er, hexdump -C myfile.blah | less | 10:17 |
| nmz787_i | yeah file just says 'data' | 10:17 |
| nmz787_i | cat shows some strings, xxd isn't terribly more interesting | 10:17 |
| nmz787_i | idk if hexdump -C is any diff than xxd | 10:17 |
| kanzure | to see strings just use the `strings` tool instead | 10:18 |
| nmz787_i | my hope is that the file actually consists of multiple compressed files or something, with headers and some ASCII in between | 10:18 |
| nmz787_i | and my hope is also that the compressed files unzip to yield ASCII text files | 10:18 |
| kanzure | a-cortesi wrote some interesting binary data file visualization tools which are helpful for figuring out weird data formats | 10:18 |
| nmz787_i | oh, hmm, I wonder if I saw a talk on that recently | 10:19 |
| kanzure | no that was anothe rdude | 10:20 |
| kanzure | ... another dude. | 10:20 |
| kanzure | (cantor dust) | 10:20 |
| nmz787_i | i remember some 80s hacker-movie style GUI, with 3D visualizations, and the person rotated the cube and maybe hid some layers and could see bitmap data in some section of the image | 10:22 |
| nmz787_i | yeah cantor dust seems more like what I remember | 10:23 |
| kanzure | yes but cortesi is the one who wrote some lightweight software to do the same thing | 10:24 |
| kanzure | http://binvis.io/ | 10:25 |
| nmz787_i | and it appears cantor.dust isn't available | 10:25 |
| nmz787_i | this seems to be a take on cantor.dust as well: https://github.com/wapiflapi/binglide | 10:25 |
| xrr | If the bytes look like /dev/urandom, I'd guess it's packed or crypted | 10:28 |
| xrr | So perhaps it would get you somewhere to find a large block of random looking bytes and try to figure out any header in front of the block | 10:29 |
| nmz787_i | binwalk shows a bunch of files paths which match the extensions of the ASCII strings I could discern (since I know what some of the CAD text files look like already) | 10:33 |
| nmz787_i | but I don't see it mention anything compressed... though the tool depends on pylzma... so maybe it did decompression itself | 10:34 |
| nmz787_i | need to try binvis too | 10:34 |
| nmz787_i | it also lists a bunch of DER certificates (x.509) | 10:35 |
| nmz787_i | but I'm not sure if that is interesting or not (some leaked keys or something???)... maybe mis-detection | 10:36 |
| nmz787_i | huh binvi.io is some kind of client-side web app | 10:40 |
| nmz787_i | hmm, it reports the file has high entropy in most areas | 10:41 |
| nmz787_i | if anyone wants to look too, download the middle file (.brd) here http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-galileo-boards/000005980.html | 10:45 |
| xrr | I'm failing to find any region that actually looks like packed. Too many 0x00-s everywhere | 10:50 |

| nmz787_i | yeah... I wonder if the encoding mixes ASCII with number data or something | 10:57 |
| nmz787_i | since this is a PCB layout, I am looking for coordinates of line points or something | 10:58 |
| kanzure | .title https://news.ycombinator.com/item?id=10751396 | 11:03 |
| yoleaux | There's Math.random(), and then there's Math.random() | Hacker News | 11:03 |
| xrr | So this is a proprietary format of Cadence Allegro right? Perhaps it can export | 11:07 |
| nmz787_i | yeah I don't want to go the export route just yet | 11:12 |
| nmz787_i | since then you'd need that software to get any existing .brd files that are online already | 11:12 |
| nmz787_i | and maybe that's against their license terms or something | 11:12 |

| kanzure | aurellem: there were some questions from docl in the backlog (around 21:15 in the logs) http://gnusha.org/logs/2015-12-16.log was wondering if you could look | 12:21 |
| aurellem | ok | 12:22 |
| aurellem | docl asked about the "paramagnetic" CPA idea -- yes it's the magnetocaloric effet | 12:24 |
| aurellem | *effect | 12:24 |
| aurellem | and unfortunately, yes you can only get like 0.1°C out of it | 12:24 |
| aurellem | it would be neat if you could get something like 15°C instead, because the magnetocaloric effect is one of the only things I know of that bypasses the surface area / volume problems of tradational organ cooling. It's also about as "instantaneous" as you can get | 12:25 |
| docl | it can't be boosted by ultra high tesla fields? | 12:26 |
| aurellem | I believe that it's a property of how much wider you make the state space of the system by turning off the field | 12:26 |
| aurellem | so you need the right sort of system | 12:27 |
| aurellem | and the best ones only get like 0.1°C right now | 12:27 |
| fenn | the cells alive system doesn't seem to use the magnetocaloric effect | 12:30 |
| fenn | it depends on low strength alternating magnetic fields to prevent crystal nucleation | 12:31 |
| aurellem | I don't think that the cells alive system actually works | 12:36 |
| aurellem | their paper should have tested the CAS system with the field on vs off | 12:37 |
| kanzure | what's the reference for breaking gaussian barrier | 12:37 |
| aurellem | but instead it tested the CAS system with the field on vs a tradational bio freezer | 12:37 |
| aurellem | if anyone has any actually good data on the CAS system I'd really like to see it | 12:37 |
| aurellem | see for example http://www.sciencedirect.com/science/article/pii/S0011224012000284 | 12:38 |
| aurellem | as far as I know there's not anything out there that gives clear evidence that CAS works | 12:39 |

| docl | aurellem: can you comment on this? (Ben Best mentioning something he heard at a conference) http://www.evidencebasedcryonics.org/2009/09/13/the-2009-sens-conference/ | 13:17 |
| docl | Dr. Kletetschka’s approach is based on the idea that if a cryonics patient were perfused with a solution containing gadolinium (nanoparticles would be best), an entire vitrified brain could be cooled uniformly by the magnetocaloric effect. | 13:17 |
| yoleaux | A ferromagnetic model for the action of electric and magnetic fields in cryopreservation | 13:17 |
| docl | it sounds to me like maybe Ben misunderstood, or Gunther was being wildly optimistic. | 13:18 |

| Alcyius | The ahole who jacked up the toxoplasmosis drug price got arrested for fed security fraud | 13:43 |
| fenn | that's like a rite of passage in his social circles | 13:44 |
| Alcyius | Yeah fair enough | 13:44 |
| kanzure | i suspect that the system design is mostly to blame not for individuals acting in their interest... | 13:44 |
| kanzure | i'm sure he's an asshole but that's irrelevant | 13:44 |
| Alcyius | The medical system shouldn't be composed of people "acting in their own interest" when it comes to people's lives | 13:45 |
| kanzure | we are still lacking a comprehensive pharmaceutical funding pipeline reform plan; lotta "innovation health prize funds" have been proposed but there's a bunch of trouble at the intersection of venture capital and health funds and patents and biotech and medicine.. | 13:45 |
| fenn | i would settle for something that just got the research results we already have into clinical practice | 13:46 |
| fenn | i don't think "pharmaceutical funding" is the problem | 13:46 |

| fenn | pharmaceuticals are what is being funded because that's what VC's can make money on, patentable mass-produced small molecules | 13:47 |
| fenn | the artificially high barriers to certifying a new type of medical treatment are what is the problem | 13:47 |

| kanzure | health insurance? underwriting? | 13:49 |
| Alcyius | And again, I really don't think that "recouping $200m" should be the goal when it comes to saving peoples lives. I get that our current system makes it impossible for anyone but major pharma corps to research new drugs, but maybe the whole profit motivation isn't the best way to do it here | 13:49 |
| kanzure | what does that have to do with condemning him as an asshole? | 13:50 |
| Alcyius | I mean, he's an asshole regardless, that was just a critique of our medical research establishment in general | 13:50 |
| kanzure | also, that seems contrary to "people shouldn't be acting in their interests" | 13:50 |
| kanzure | health is definitely in my own interest. so..... | 13:51 |
| * kanzure goes away confused | 13:51 | |
| Alcyius | More, it shouldn't be up to the private sector to research live-saving medical treatment | 13:51 |
| Alcyius | I mean, by all means they CAN, but there needs to be something more | 13:51 |
| Alcyius | Though I don't trust the government as it is | 13:51 |
| Alcyius | But yeah, the clinical trial and research costs are the biggest barrier | 13:52 |
| kanzure | today is not a good day | 13:53 |

| aurellem | docl: look here: https://en.wikipedia.org/wiki/Magnetic_refrigeration | 17:39 |
| aurellem | I don't quite understand how you would be able to remove the heat from the dipoles once they're inside the brain | 17:40 |
| aurellem | so you would, at best, get only one shot to do this, which wouldn't be enough | 17:40 |
| aurellem | well unless you were perfusing I guess | 17:40 |
| aurellem | but then you could just cool the perfusate with actual refridgerators | 17:40 |

| docl | hmm. the particles all would increase in magnetic field as soon as they warm back up due to surrounding fluid being warmer. | 18:14 |
| -!- zincomentario [~x@176.10.248.228] has joined ##hplusroadmap | 18:15 | |
| aurellem | so lets say you get the particles into the brain slowly, with a strong magnetic field | 18:15 |
| docl | theoretically, that makes a pulse of electromagnetism, i.e. visible or radio spectrum | 18:15 |
| docl | right | 18:15 |
| aurellem | then you can release the field and it will cool the brain down instantly | 18:15 |
| aurellem | but then you can't do it again | 18:15 |
| docl | right | 18:15 |
| aurellem | and the effect is really small | 18:15 |
| aurellem | even with the materials that Best is talking about | 18:16 |
| -!- nmz787_i [~ntmccork@134.134.139.74] has quit [Quit: Leaving.] | 18:16 | |
| aurellem | like with REALLY strong magnets and undre ideal conditions, you MIGHT get 1°C, and that's really stretching it | 18:17 |
| aurellem | work out the math and see what you get | 18:17 |

| docl | still trying to grok the math, had to look up the curly d symbol (and here fenn thinks calculus is useless :P) | 19:28 |
| docl | and today I learned the reason I could never put my finger on what greek letter that was, apparently, is because it isn't a greek letter at all, just some french guy's weird cursive version of a d | 19:31 |
| fenn | it's a lowercase delta | 19:31 |
| -!- atomical [~atomical@209.153.22.182] has quit [Quit: My Mac has gone to sleep. ZZZzzz…] | 19:31 | |
| docl | https://en.wikipedia.org/wiki/%E2%88%82 this one | 19:32 |
| docl | compare to: https://en.wikipedia.org/wiki/Delta_%28letter%29#Lower_case | 19:33 |
| fenn | oh the first one hooks over to the left instead of the right | 19:34 |
| fenn | i've seen it both ways | 19:34 |
| docl | https://en.wikipedia.org/wiki/List_of_mathematical_symbols refers to the left hook one as rounded d. it redirects from https://en.wikipedia.org/wiki/Rounded_d to the unpronounceable unicode link above. | 19:38 |
| docl | right hook one is functional derivative. left hook (rounded d) is partial derivative. | 19:39 |
