Apr 02 04:54:02 <Church-_> Hmm, better than #n900
Apr 02 14:56:36 <kerio> DocScrutinizer05: will openbsd run on the neo900?
Apr 02 14:59:01 <DocScrutinizer05> sure, why not?
Apr 02 14:59:15 <DocScrutinizer05> does openBSD run on beagleboard?
Apr 02 14:59:31 <kerio> yes
Apr 02 14:59:36 <kerio> http://www.openbsd.org/armv7.html a very small handful of boards
Apr 02 14:59:41 <DocScrutinizer05> so, there's your answer
Apr 02 14:59:45 <kerio> yay ^_^
Apr 02 15:00:35 <kerio> ...is the neo900 just a beagleboard that you guys scrunched up to fit in the n900 case? ¬.¬
Apr 02 15:00:36 <DocScrutinizer05> we even use BB-xM for "emu" in proto_v2
Apr 02 15:00:54 <DocScrutinizer05> sort of, plus we added tons of peripherals
Apr 02 15:01:10 <DocScrutinizer05> btw same applies for N900
Apr 02 15:01:17 <DocScrutinizer05> and for GTA04
Apr 02 15:01:41 <kerio> hm, is there any arm board with pcie 3.0
Apr 02 15:01:52 <DocScrutinizer05> dunno of any
Apr 02 15:02:06 <DocScrutinizer05> maybe OMAP5 has such stuff
Apr 02 15:02:52 <DocScrutinizer05> seems it has SATA, so why not PCIE3
Apr 02 15:03:08 <DocScrutinizer05> never closely looked into it
Apr 02 15:03:53 <kerio> will http://www.intel.com/content/www/us/en/solid-state-drives/solid-state-drives-750-series.html work with the neo900
Apr 02 15:04:07 <kerio> it would add quite a lot of very fast swap
Apr 02 15:04:16 <DocScrutinizer05> honestly now, you tell us :-)
Apr 02 15:05:23 <kerio> no arm board supports any of those fancy connectors :(
Apr 02 15:05:27 <kerio> no nvme, no m.2
Apr 02 15:05:28 <DocScrutinizer05> you got USB2.0 and UART as fast interfaces
Apr 02 15:05:42 <kerio> """fast"""
Apr 02 15:06:14 <DocScrutinizer05> well, 480Mbit is already at the limits of the complete system
Apr 02 15:06:51 <DocScrutinizer05> I mean, you not only need to transfer data, you also need to *do* sth with it
Apr 02 15:07:48 <DocScrutinizer05> when you can't even transfer it to RAM anymore then your bottleneck is elsewhere, not in bandwidth of interface
Apr 02 15:08:40 <kerio> just overclock the shit out of the ram
Apr 02 15:08:41 <kerio> ez
Apr 02 15:08:51 <DocScrutinizer05> well, the RAM is still a tad faster than USB2 I think, but not like magnitudes faster
Apr 02 15:08:58 <kerio> wait, really?
Apr 02 15:09:00 <kerio> :o
Apr 02 15:09:53 <kerio> fast unbuffered ram can reach 20GB/s
Apr 02 15:10:01 <kerio> (ddr3 on intel)
Apr 02 15:10:15 <DocScrutinizer05> with a OMAP3? dream on
Apr 02 15:10:26 <kerio> weirdly enough, the best ddr4 is slower than that
Apr 02 15:10:45 <DocScrutinizer05> we got LPDDR2-133 iirc
Apr 02 15:11:16 <DocScrutinizer05> maybe even -200
Apr 02 15:11:55 <DocScrutinizer05> if my math doesn't suck due to lack of caffeine, that's still just 4 times the speed of USB2.0, roughly
Apr 02 15:12:52 <DocScrutinizer05> and you need to handle the IO too, which needs to get done in CPU land, either in sw or at least by DMA
Apr 02 15:15:04 <DocScrutinizer05> I could be wrong by factor2 or even 4, with my math
Apr 02 15:15:15 <DocScrutinizer05> still... you get the picture
Apr 02 15:15:50 <kerio> ye ye
Apr 02 15:15:54 <kerio> i was only mostly kidding
Apr 02 15:17:37 * kerio is still looking for a ram-based, volatile microsd
Apr 02 15:19:53 <DocScrutinizer05> holler if you find any, would be a really nice device indeed
Apr 02 15:24:42 <DocScrutinizer05> anyway on OMAP3 iirc the SDcard interface is limited to 48Mhz clock and, for uSD, 4 bit bus width, which makes 24MB/s in my book
Apr 02 15:25:54 <DocScrutinizer05> eMMC has 8bit bus, thus twice that
Apr 02 15:26:17 <DocScrutinizer05> so it's somewhat on par with USB2.0
Apr 02 15:26:34 <kerio> ...i didn't realize that the uSD was that slow
Apr 02 15:28:48 <ceene> is the ram on n900 replaceable?
Apr 02 15:31:03 <DocScrutinizer05> plainly no
Apr 02 15:31:38 <ceene> can't the chip be unsoldered and replaced?
Apr 02 15:31:39 <DocScrutinizer05> some tried it, I never heard again from any of them
Apr 02 15:32:20 <DocScrutinizer05> we did something similar on beagleboard-xM to test our 1GB RAM
Apr 02 15:32:56 <DocScrutinizer05> which took highly sophisitcated rework station and experienced personal to get accomplished
Apr 02 15:33:30 <ceene> is it bga or something like that?
Apr 02 15:33:49 <DocScrutinizer05> and we swapped the complete SoC/RAM&NAND PoP stack
Apr 02 15:33:57 <DocScrutinizer05> it's PoP
Apr 02 15:34:02 <kerio> DocScrutinizer05: yeah but can you clean the fans of my macbook pro?
Apr 02 15:34:32 <DocScrutinizer05> yes, I'll use pressurized air and kill your macbook ;-P
Apr 02 15:34:49 <kerio> https://www.ifixit.com/Device/MacBook_Pro_15%22_Retina_Display_Late_2013
Apr 02 15:34:52 <kerio> Repairability: 1 / 10
Apr 02 15:34:53 <DocScrutinizer05> I did so with other notebooks before
Apr 02 15:35:08 <kerio> i cleaned my mom's non-retina macbook, it was very very easy
Apr 02 15:35:14 <kerio> other than the fan connector being kinda thin
Apr 02 15:35:17 <kerio> this one is insane tho ._.
Apr 02 15:35:29 <DocScrutinizer05> a fan at several 1000s of RPM can create amazing amount of voltage fed to the PCB
Apr 02 15:35:37 <kerio> still haven't tried it, because "Step 1 - Remove the following pentalobe screws"
Apr 02 15:35:53 <kerio> i want to believe there's some protection circuit, but probably not
Apr 02 15:36:06 <DocScrutinizer05> no obviously there isn't
Apr 02 15:36:28 <DocScrutinizer05> "how pressurized air can make your electronics go up in smoke"
Apr 02 15:36:29 <kerio> there's glue EVERYWHERE
Apr 02 15:36:37 <kerio> ;-;
Apr 02 15:37:29 <ceene> does that happen?
Apr 02 15:37:37 <kerio> sure
Apr 02 15:37:57 <kerio> there's a reason it's very very recommended to detach the fans and prevent them from spinning when using compressed air
Apr 02 15:37:59 <ceene> i'm used to clean pcs with air
Apr 02 15:38:16 <ceene> does that break them?
Apr 02 15:38:40 <DocScrutinizer05> ceene: see https://en.wikipedia.org/wiki/Package_on_package
Apr 02 15:38:58 <ceene> DocScrutinizer05: yeah, i was reading that
Apr 02 15:39:03 <DocScrutinizer05> ceene: yes, when the fann starts to spin very fast
Apr 02 15:39:20 <ceene> i don't think any of the people i know at my uni would be able to unsolder that
Apr 02 15:39:43 <ceene> oh, i've made several of them do that... just for fun :/
Apr 02 15:39:53 <ceene> didn't know it was harmful :/
Apr 02 15:44:06 <DocScrutinizer05> I killed two laptops this way, without disassembling them
Apr 02 15:44:34 <DocScrutinizer05> the first was learning, the second was idiocy
Apr 02 15:44:59 <DocScrutinizer05> I thought I could control the effect by only blowing gently 
Apr 02 15:45:11 <DocScrutinizer05> with a 10 bar canned air
Apr 02 15:45:15 <DocScrutinizer05> ;-P
Apr 02 15:45:43 <ceene> i use a pressurizer :)
Apr 02 15:46:06 <ceene> but i've only cleaned desktop computers, never a laptop
Apr 02 15:48:27 <DocScrutinizer05> anyway my recommmendation is: make DAMN SURE you block the fan from spinning for good, before you approach it with pressurized air or vacuum cleaner
Apr 02 15:49:05 <ceene> will do from now on
Apr 02 15:49:05 <DocScrutinizer05> for added peace of mind, disconnect the fan from PCB if any possible
Apr 02 15:49:30 <DocScrutinizer05> so if your block fails, only the fan will go south
Apr 02 16:34:52 <kerio> DocScrutinizer05: motha
Apr 02 16:34:52 <kerio> fuckin
Apr 02 16:34:54 <kerio> chopsticks
Apr 02 16:35:59 <DocScrutinizer05> huh?
Apr 02 16:36:19 <DocScrutinizer05> yes, stick a chopstick to fan
Apr 02 17:31:03 <Vajb> i made silent pc once by chopsticking psu fan :p
Apr 02 17:33:18 <kerio> Vajb: 10/10
Apr 02 20:29:44 * DocScrutinizer05 often pondered making silent PC by simly adding a chimney
Apr 02 20:30:17 <DocScrutinizer05> the hotter the air, the better it works. Just like it should be :-)
Apr 02 20:30:38 <DocScrutinizer05> and absolutely zilch noise
Apr 02 20:44:54 <M4rtinK> yeah, should work quite nicely
Apr 02 20:45:04 <M4rtinK> as long as you have enough space for that
Apr 02 20:45:05 <sixwheeledbeast> Remove all the fans from the cab
Apr 02 20:45:34 <M4rtinK> & the box is reasonably airtight with an opening at the bottom
Apr 02 20:45:58 <sixwheeledbeast> then point a desk fan in there...
Apr 02 22:33:36 <Maxdamantus> Just make a vacuum box with another box suspended inside to hold the PC.
Apr 02 22:33:48 <Maxdamantus> like a thermus.
Apr 02 22:34:22 <Maxdamantus> thermos* maybe.
Apr 02 22:36:19 <Maxdamantus> wait, that's stupid.
Apr 02 22:36:26 <Maxdamantus> The heat won't be able to escape.
Apr 02 23:13:33 <robotanarchy_> Wizzup_/everybody else: so... do you have ofono working on a non-maemo distro with a recent kernel? I'm running debian900 with the 4.5-rc7 and 4.6-rc1 kernel, but ofono can't find the modem there.
Apr 02 23:13:49 <robotanarchy_> kernels are from pali's branch
Apr 02 23:16:39 <robotanarchy_> pali: besides that, the 4.6-rc1 kernel seems to work fine :)
Apr 02 23:17:17 <kerio> woop
