[01:24] <squish102> im seeing a write speed on a Raid0 that is 2 seagate 72k 3tb drives. Only getting about 40 MB/s
[01:24] <squish102> seem about right? 
[01:24] <squish102> i would think i would get at least 70-100 MB/s
[04:34] <superfly> squish102: I don't know, I'm a software guy :-)
[06:09] <calhax> morning :)
[06:09] <night> good morning
[06:10] <night> oh, btw
[06:10] <night> I have kind of an interesting computer problem
[06:10] <night> not sure if I should be concerned
[06:10] <night>  /how concerned haha
[06:10] <night> tell me if you've ever heard of this
[06:11] <night> I can hear the CPU on my macbook
[06:11] <night> like, when it's drawing power for computations I can tell and there's a slight sqeaky noise 
[06:11] <night> noise is louder when connected to power
[06:11] <night> not the fans
[06:12] <night> can corroborate by doing operations on screen and hearing the CPU working at the same time
[06:12] <night> but basically sounds like old-style computers in the movies
[06:12] <night> dial up phone noises, squeaks and clicks at different speeds
[06:14] <night> laptop is six years old by now but I planned its service lifetime around using it for another 12 months
[06:14] <night> hoping motherboard power supply won't fry
[06:18] <paddatrapper> morning calhax, night, everyone
[06:18] <paddatrapper> night: are you sure it isn't a fan that is kicking up on high-intensity work loads?
[06:19] <night> paddatrapper: I'm hoping it's something to do with that but I wouldn't be able to explain it
[06:19] <paddatrapper> CPU is solid state, so (unless something is arcing), there shouldn't be any noise...
[06:19] <night> fan stays steady at 2000 rpm but weird power situation might cause interference in either those or the speakers
[06:19] <night> correct
[06:20] <paddatrapper> thats really weird! :)
[06:20] <night> it's also really cool!
[06:20] <night> I can hear when it's doing things in the background, and at what frequency
[06:20] <night> just have to expect impending doom 
[06:21] <paddatrapper> I've heard of people who get their CPUs to modulate FM frequencies (or someother EM frequency), but actual noise is a first
[06:21] <night> something's gotta be arcing or oscillating in the circuit in a way it shouldn't
[06:21] <night> lol
[06:21] <paddatrapper> certainly sounds like it
[06:21] <night> yeah it's PSU somehow
[06:21] <calhax> could be a unhappy capacitor night 
[06:21] <night> since my computer doesn't have any other independent components I can say the sound is representative of the CPU
[06:22] <night> calhax: I've taken some electrical classes but don't know what capacitors are like in failure
[06:22] <night> so that's a possibility?
[06:22] <night> hm
[06:22] <night> I've blown up a few transistors and assorted chips but never a capacitor haha
[06:24] <paddatrapper> night: generally that don't make much sound, maybe some popping if there are arcs. visually the tops tend to blacken or bulge
[06:25] <night> okay, paddatrapper 
[06:25] <night> good info :) 
[06:26] <night> only way I can think of capacitors failing is current overload
[06:26] <calhax> night, it's no unusual for a electronic circuit to act out of character when a cap is damaged, caps smooth voltage and frequency, since you are hearing a frequency it could be a faulty cap on you MB that is not filtering the sound out, just a thought, it could be a hundred different things LOL
[06:27] <night> right
[06:27] <night> that makes a lot of sense
[06:28] <calhax> night, how old is the machine?
[06:28] <night> calhax, if that's the case, yeah it wouldn't be an immediate problem
[06:28] <night> might just expose downstream components to higher wear rate
[06:28] <night> calhax: good question, it's getting old 
[06:28] <night> 6 years
[06:28] <night> no problems in those 6 years though!
[06:30] <calhax> night, could be caps are unpredictable, however have you tried unplugging all of your peripherals and checking if it still does the same thing, if a peripheral draws more than 500mA on a USB port it is technically putting that USB under strain
[06:31] <night> calhax: noise occurs with all ports disconnected
[06:31] <night> you bring up a good point, though, which is that the source might be able to be isolated by seeing if peripherals can prompt the noise too
[06:32] <night> charging port --> PSU --> peripheral bus | internal components
[06:32] <calhax> night, have you tried taking the battery out and just run it on AC?
[06:32] <night> haha
[06:32] <calhax> lol
[06:32] <night> do you think apple would like that?
[06:32] <night> I gotta try this
[06:32] <night> I feel like macOS will say something about that
[06:34] <night> I have just remembered a incident in the lab a few weeks ago
[06:34] <night> was running a microcontroller powered via laptop's USB
[06:34] <paddatrapper> if mac has dmesg, USB over-current should be reported there
[06:35] <night> paddatrapper: yes, this over-current was brought up as a notification
[06:35] <night> some kind of internal breaker tripped and shut off the peripheral
[06:35] <night> was kind of cool, actually, hadn't seen that before
[06:36] <paddatrapper> it is pretty cool, have had that happen occasionally when I've been working on microcontroller stuff, but luckily no damage
[06:38] <night> paddatrapper: curious if that protection is all virtual
[06:38] <night> if there are physical breaker components those would wear out over time
[06:39] <paddatrapper> night: It is certainly controlled virtually, but I suspect the bus is never actually disconnected (because the other port on the same bus worked for me). The OS probably just doesn't allocate power to it
[06:42] <calhax> paddatrapper, could be reading current over the port and shutting it down when its out of range
[06:43] <paddatrapper> calhax: I'm pretty sure that is what happens, but I don't think there is a physical breaker on the bus
[06:44] <night> thank you all for the input, I hadn't considered capacitor problems and will do a bit of testing
[16:03] <superfly> o/
[16:38] <paddatrapper> superfly: hi
[17:54] <nsnzero> evening all
[18:52] <Kilos> hi guys, have a good night. i go sleep more
[19:04] <inetpro> good evening
[19:47] <superfly> hey paddatrapper, how's things?
[19:47] <superfly> inetpro: o/
[20:21] <paddatrapper> superfly: alright thanks. A little swamped, but not much more than usual. You? 
[20:46] <superfly> paddatrapper: going well, thanks. Getting settled in here.
[20:47] <superfly> paddatrapper: my boss and my team lead are apparently really happy with my progress so far
[21:02] <paddatrapper> superfly: awesome :)
[22:20] <superfly> paddatrapper: I don't know if you remember that box of books I shipped over?
[22:21] <superfly> paddatrapper: well, we gave up, thinking it was lost. I even bought myself a new study Bible.
[22:21] <superfly> paddatrapper: it rocked up at mrs_fly's mom's house today
[22:21] <superfly> finally
[22:33] <paddatrapper> superfly: that certainly took a while! 
[22:34] <paddatrapper> That's pretty much as bad as ebay shipments when sent to here... 
[22:36] <superfly> I've had an ebay shipment in 6 weeks
[22:36] <superfly> this was more like 6 months
[22:44] <paddatrapper> Painful 
[23:04] <superfly> Tomorrow I'm going to an Ubuntu installfest in Phoenix
