[16:32:29] <Roguish> FACETIME MUST DIE
[16:33:37] <Jymmm> Roguish: Um, don't use it?
[16:33:52] <roycroft> what is facetime? :)
[16:34:02] <Roguish> that is an option.............no one forces us
[16:34:06] <Jymmm> roycroft: video conferencing

[16:34:26] -!- elomin has quit [Ping timeout: 240 seconds]
[16:34:27] <roycroft> i did something a day or two ago that caused a facetime window to pop up on my imac
[16:34:34] <roycroft> first time that's ever happened
[16:34:51] <roycroft> fortuantely, facetime demanded that i log into my icloud acount before it would do whatever it intended to do
[16:35:21] <roycroft> since i have no icloud account and never shall, i figure i'm pretty well-insulated from things facetimish
[16:36:10] <Jymmm> roycroft: I just toss tape over the camera =)
[16:36:34] <XXCoder> yeah I always cover camera in case there was a rootkit
[16:37:19] <roycroft> i have definitely put labels over my cameras on all my devices
[16:37:27] <roycroft> save the rear facing camera on my iphone
[16:37:38] <roycroft> however, there is still a built-in microphone
[16:39:34] <Jymmm> roycroft: true enough
[16:43:02] <fragalot> desolder the microphone
[16:43:15] <fragalot> its not like you use your phone for calling anymore anyway
[16:43:26] <fragalot> :D
[16:44:37] <Deejay> gn8
[16:45:32] -!- Deejay has quit [Quit: bye]
[16:47:53] <roycroft> 98% of my iphone usage is listening to music
[16:48:12] -!- gloops has quit [Ping timeout: 250 seconds]
[16:48:13] <roycroft> the other 2% is reluctantly conducting telephony operations
[16:48:37] <roycroft> all those apps that are on the phone are useless
[16:48:42] <roycroft> i use an ipad for portable apps
[16:48:55] <roycroft> the screen on an iphone is way too small for that stuff
[17:00:38] -!- Papagno has quit [Quit: Sto andando via]
[17:05:39] <rmu> fragalot: microphoneS
[17:06:18] <rmu> i think there is a howto-video by ed snowden
[17:06:56] <fragalot> good point
[17:07:24] <fragalot> bet someone clever managed to use data analysis on the accelerometers to pick up audio too
[17:08:08] <rmu> no that won't work
[17:09:06] <fragalot> given that Loetmichel is capable of viewing what's on your monitor from 100m away based on nothing but electrical noise.. I'm pretty sure that it is possible, even if you'd have to look deep within the noise floor of the data
[17:09:35] <fragalot> heck, LoRa is broadcasting its data well below the noise floor and somehow the messages still make it through
[17:09:46] <rmu> those MEMS accelerometers (at least those i know) are quite noisy, limited to about 1khz sample rate, at a resolution of 0,01m/s^2
[17:10:45] <fragalot> 1kHz is good enough
[17:11:51] <rmu> if you get useful data at 1 khz, but even if you keep those things at rest (in a quiet environmen) they fluctuate quite hefty
[17:12:08] <fragalot> thats where major data analysis comes into play
[17:12:11] <fragalot> i'm not saying it'd be easy
[17:12:19] <fragalot> or very reliable
[17:12:21] <fragalot> just not impossible
[17:12:39] <rmu> but it seems somebody already did it
[17:12:47] <rmu> https://www.engadget.com
[17:13:05] <fragalot> in 2014, and sensors have only gotten better since :P
[17:13:22] <fragalot> some people have even managed to get audio from video-only sources
[17:13:57] <rmu> https://www.reddit.com
[17:14:56] <rmu> nevertheless i don't believe this really works to eavesdrop on people
[17:15:29] <fragalot> why wouldn't it, assuming you have full access to the device in question?
[17:16:40] <rmu> not enough SNR
[17:17:15] <fragalot> that's only a matter of getting very large data sets & a lot of time
[17:17:33] <rmu> with lora and gps you know something about the signal that allows you to discriminate it from the noise
[17:19:07] <rmu> lot of time and very large dataset seems unpractical for eavesdropping
[17:19:46] <fragalot> depends on how valuable the potential information is
[17:22:07] <rmu> then it will become "cheaper" to use a bat
[17:22:12] <fragalot> :p
[17:22:41] <MarcelineVQ> with everyone having smarttv's and alexa and cortana etc you don't even need to get clever with your monitoring sensors
[17:23:01] <rmu> exactly
[17:23:06] <fragalot> of course
[17:23:24] <fragalot> I'm just a fan of creativity >.>
[17:23:39] <MarcelineVQ> well sure, that's the tagline of the channel :>
[17:24:05] <fragalot> up next: use raw data from your harddisks' magnetic sensor thingymajigger to measure audio vibrations
[17:24:29] <rmu> for the real secret stuff i go into the basement into the copper-clad concrete bomb shelter. no phones or any kind of electricity except flashlights allowed there.
[17:24:43] <fragalot> rmu: flashlights?
[17:24:51] <fragalot> did you not know that some batteries have memory effect???
[17:24:58] -!- EntropyWizard has joined #linuxcnc
[17:24:58] <rmu> hehehe
[17:25:10] <fragalot> rookie mistake right there
[17:25:52] <rmu> and those head-lamps could do EEG covertyl, read your brain
[17:27:06] <rmu> given enough sample data and time they could discriminate if i think of red or white wine when looking at the wine rack ;)
[17:27:37] <fragalot> based on your electricity consumption
[17:27:41] <fragalot> "oh he opened the fridge"
[17:28:59] <rmu> "and now the pre-checkin testsuite is running"
[17:32:47] * Jymmm looks at channel name, Nope not #conspiracytheory ;)
[17:33:09] <fragalot> it's not a theory! *crinkles tin foil hat*
[17:34:20] <jthornton> hmm I had a copy of the probe routines that someone wrote I think cradek wrote them now I can't find them
[17:35:07] <Jymmm> fragalot: https://www.nytimes.com
[17:37:07] <CaptHindsight> Jymmm: because most people just don't care
[17:37:14] <CaptHindsight> even when made aware

[17:37:41] -!- gloops has joined #linuxcnc
[17:37:42] <fragalot> interesting, my 3D printer now has a very audible alarm that it has finished
[17:37:51] <Jymmm> CaptHindsight: Which is the biggest thing of them all
[17:38:18] <fragalot> (the bit hitting my homing sensor appears to ahve broken off so it just hit the end of travel & heavilly vibrated as it lost steps)
[17:39:02] <CaptHindsight> Jymmm: you could make getting shot in the head a status symbol and people would fight to be first in line
[17:39:38] <Jymmm> CaptHindsight: only for the PC purpose,
[17:40:03] <Jymmm> jthornton: lol, blame chris for the broken link... https://sourceforge.net
[17:41:04] <CaptHindsight> fragalot: which version Yoda head did you make? :)
[17:41:07] <rmu> most people volunteer everything there is to know about them to facebook
[17:41:11] <Jymmm> jthornton: https://github.com
[17:41:41] <fragalot> CaptHindsight: hehe. printed some new plastic drawer runners to replace a set that broke after 20yrs of service
[17:41:51] <Jymmm> rmu: You forget Google, a commercial division of the NSA
[17:41:52] <jthornton> na smartprobe.ngc is a surface probe routine
[17:43:17] <CaptHindsight> Jymmm: have you been deputized? Please signify by not answering since you are under a gag order.
[17:43:54] <Jymmm> CaptHindsight: Hrmurmurumhmmm
[17:49:35] <Jymmm> CaptHindsightFor the record, any gag order I'e had expired long ago

[17:53:14] <jthornton> close as I came to finding them again was The requested URL /cradek-files/01262579508/P-back.ngc was not found on this server.
[18:01:21] <jthornton> dang I have dozens of probe files adapted from chris radek but can't find the originals

[18:08:51] <jthornton> awesome
[18:12:32] <_unreal_> why Thats no flood. Thats a tsunami
[18:12:33] <jthornton> got them all saved now thanks Jymmm
[18:12:57] <Jymmm> jthornton: glad I could help =)
[18:13:20] <Jymmm> _unreal_: Hey, I gave warning and tried to save jthorntonsoem bandwidth =)
[18:13:58] * jthornton goes to do a bed check in the coop
[18:19:50] <jthornton> Jymmm: that is just awesome!
[18:21:32] <Jymmm> jthornton: whats that?
[18:23:01] <jthornton> you finding cradek probing files
[18:23:56] <Jymmm> jthornton: Oh, no worries, I hate when crap liek that happens so frustrating, then I know your only have 50% bandwidth left, that that just bites
[18:29:31] <jthornton> 46% left lol but I'm gaining
[18:29:47] <Jymmm> haha

[21:41:17] <norias> springs steels
[21:41:21] <norias> tool steels
[21:41:26] <norias> mostly
[21:41:37] <norias> 6150, H13
[21:41:48] <norias> i'm mostly concerned with H13 at this point

[21:48:04] <Tom_itx> or do it the ghetto way and heat it to a cherry red and dip it in oil
[21:49:16] <norias> yeah, ghetto way is not going to work
[21:49:30] <Tom_itx> then you need a good oven and a timer

[22:39:55] <skunkworks> andy would be a good resource for heat treating I bet
[22:43:18] <CaptHindsight> i have a heat treater 300ft from me, big induction stuff
[22:44:22] <CaptHindsight> always smells like burned metal at night when the winds come from that direction
[22:44:32] <CaptHindsight> think electrical fire
[23:24:26] <Jymmm> CaptHindsight: you wired it backwards?
[23:25:57] <Tom_itx> 23°F with sleet / hail & lightening
[23:26:08] <Tom_itx> weird
[23:26:19] <CaptHindsight> Jymmm: AC battery?
[23:26:51] <Jymmm> CaptHindsight: coconut battery ka gilligans island???
[23:26:58] <Jymmm> Tom_itx: you poor bastard
[23:27:11] <Jymmm> aka*
[23:27:43] <Tom_itx> you in so-cal?
[23:27:49] <Tom_itx> what's it like there?
[23:28:23] <Tom_itx> err you're furthere north i think..
[23:28:55] <Jymmm> Tom_itx: NorCal, #campfire
[23:29:42] <Jymmm> Tom_itx: I'm in the forest, ~2500ft elevation
[23:31:47] <roycroft> jymmm is in way-nocal
[23:31:52] <roycroft> it's a different universe from socal
[23:32:12] <Tom_itx> the whole of Ca is a different universe
[23:32:39] <Tom_itx> serious thunder here...
[23:34:15] <Jymmm> roycroft: https://en.wikipedia.org(2018)
[23:34:23] <roycroft> we have a dusting of snow in rhe forecast for later this week
[23:34:33] <roycroft> we had a wee bit tuesday morning
[23:34:58] <roycroft> i'm well acquainted with the camp fire, jymmm
[23:35:11] <Jymmm> roycroft: the fire moved a football field per second
[23:35:49] <roycroft> we had some really bad fires last year, but nothing like the camp fire
[23:35:58] <roycroft> what's really sad is that there is no longer a "fire season" in cali
[23:36:01] <CaptHindsight> we are back to 0F on Friday :(
[23:36:07] <roycroft> there are fires year-round now
[23:36:24] <roycroft> we're forecast to get down to -4c tonight
[23:36:56] <roycroft> in fact, it's forecast to get below freezing most nights over the next week
[23:37:00] <roycroft> very unseasonably cold
[23:38:58] <CaptHindsight> we were just at 50F
[23:39:15] <CaptHindsight> we just swing back and forth every week now
[23:39:42] <CaptHindsight> +20F warmer than average to -20F than
[23:40:02] <CaptHindsight> ice storm yesterday and night
[23:40:33] <CaptHindsight> every branch and twig had a layer of ice, lasted all day
[23:40:38] <CaptHindsight> looked like scifi
[23:41:20] <CaptHindsight> Jymmm: why did the fire move a football field?
[23:41:43] <CaptHindsight> how many do you have?
[23:46:11] <Jymmm> CaptHindsight: 150,000 acres worth
[23:46:34] <CaptHindsight> Jymmm: hoe close was that fire to you?
[23:46:38] <CaptHindsight> how
[23:46:51] <Jymmm> CaptHindsight: 2 miles
[23:47:05] <CaptHindsight> Jymmm: did you evacuate?
[23:47:10] <Jymmm> CaptHindsight: Well, could be less depending with direction
[23:47:23] <Jymmm> CaptHindsight: Oh hell yes.
[23:47:38] <CaptHindsight> Jymmm: how long were you gone from home?
[23:47:47] <Jymmm> CaptHindsight: over a month
[23:47:50] <CaptHindsight> wow
[23:47:57] <Jymmm> had to sneak back in twice
[23:48:26] <CaptHindsight> so you had a little bit of info that your place was safe
[23:48:36] <CaptHindsight> still safe
[23:49:02] <Jymmm> sat thermal image maps
[23:49:23] <Jymmm> *live
[23:49:41] <CaptHindsight> did surrounding the lot with a urine moat work?
[23:49:46] <roycroft> don't forget to rake your forest in the spring, jymmm
[23:50:33] <Jymmm> The fire was very strange... some places took out like 40 houses, then one standing in perfect condtion,
[23:50:51] <CaptHindsight> saw that on the news
[23:51:23] <CaptHindsight> was it due to the construction of the home or just the fire direction/wind luck?
[23:51:32] <Jymmm> The hardest part for me was getting past chp and national guard road blocks
[23:51:43] <roycroft> fires are like tornados in that respect
[23:51:48] <CaptHindsight> what story did you use?
[23:52:02] <Jymmm> No, that's whats strange , the places that were still standing had ZERO damage at all.
[23:52:17] <Jymmm> The trusth, and brought donuts (for real)
[23:53:01] <CaptHindsight> how far past the road blocks was your home?
[23:53:22] <CaptHindsight> heard they were shooting looters
[23:53:25] <Jymmm> I had to hike in the first time (wasn't aware of the SECOND roadblock), got caught by sherrrifs' then they actually drove me the rest of the way
[23:53:50] <CaptHindsight> oh nice
[23:53:53] <roycroft> that was nice of them
[23:54:00] <roycroft> and they could keep an eye on you
[23:54:10] <Jymmm> Yeah, saved me the last two miles
[23:54:23] <Jymmm> Nope, they left me
[23:54:25] <CaptHindsight> how far was the fire at time from you?
[23:54:51] <CaptHindsight> hike through smoke?
[23:55:27] <Jymmm> It came in the back road, which was a green zone, bordered by red zone (where I needed to go),
[23:56:21] <Jymmm> No, it was "safe" (fire/smoke wise), they just were restrting access
[23:56:36] <Jymmm> restricting, to prevent looters mostly
[23:57:19] <Jymmm> but needed to get meds that were at the house
[23:57:38] <CaptHindsight> Jymmm: how are the house projects? electrical, salt heat storage etc
[23:58:28] <Jymmm> the second time, came across a lost CHP, so lead him across 16 miles of dirt roads to where he needed to be. So he just truened his back and let us through, no hiking YAY!!!
[23:58:49] <Jymmm> Electrical is all done.
[23:59:56] <Jymmm> Heat, eh, still working on that currently, not having much luck in gettong from 1400F to 140F in the confined space
