15:47.58DocScrutinizer05on quality LiIon batteries
15:48.48DocScrutinizer05so all my batteries are floating on charger attached at 4168mV@0.0mA average
15:49.12DocScrutinizer05if yours doesn't and consumes current constantly, discard it!
15:49.53DocScrutinizer05and no, my LiIon do not exactly suffer undue harm and damage from this scheme
15:50.27DocScrutinizer05as a >60% after 5 years 24/7 proves
15:56.50DocScrutinizer05((so the device never reaches charge-end current threshold)) this is due to the charger chip not only charging battery but also providing power to the complete system, and it can't discern between the two sinks
15:58.35DocScrutinizer05so BQ24150 never will see charge end current threshold reached when system consumes significant power. BQ27200 gas gauge chip otoh *can* measure clean plain battery current, but this is not used to control the charger chip

16:01.47DocScrutinizer05BME might once have been meant to implement such correct battery current control via BQ27200 and feedback to BQ24150, but obviously it fails miserably on that task if it ever really been the task
16:03.54DocScrutinizer05BME replacement is kernel based afaik, and probably any developer would get fatal headache from fighting agaonst layering violations when they tried to implement it in a upstream-able fashion
16:05.30DocScrutinizer05in my book this isn't a kernel issue but actually best handled in a userland app that has all the knowledge about battery management
16:06.40DocScrutinizer05just like initiating a call on modem isn't a kernel task
16:13.38DocScrutinizer05(car starter batteries) because of LiIon: ~250-~340 W/kg, vs Lead Acid 180 W/kg
16:14.44DocScrutinizer05and Lead Acid 33–42 Wh/kg  vs LiIon 100–265 W·h/kg

16:15.33KotCzarnyespecially in colder/hotter climates
16:16.02DocScrutinizer05you can save up to 80% of weight with swapping lead acid for LiIon in a car
16:16.30KotCzarny80% of weitgh which is how much, 0.1% of car weigh?
16:16.32KotCzarnyseriously
16:16.36DocScrutinizer05possibly 90%
16:17.04KotCzarnyand in the case of car accident you have a bomb under the hood
16:17.21DocScrutinizer05plus LiIon is maintenance free
16:18.34DocScrutinizer05and thanks to higher power per kg, you may get away with lower capacity, after all you don't need 60Ah*12V to start an engine
16:20.44DocScrutinizer05assuming you need a maybe 150A, from a power POV you may get away with 15Ah high power LiIon
16:21.27DocScrutinizer05NB those latter 4 or 5 lines are numbers right from my rear
16:24.16DocScrutinizer05anyway according to the math, a 50Ah Lead Acid weighs ~18kg - quite worthy target for optimizations
16:24.35DocScrutinizer05oops sorry typo: 60ah
16:27.18DocScrutinizer05hmmm 14kg https://www.amazon.de/Varta-58360-Autobatterie-Dynamic-Preis/dp/B00RZ56PPW

16:30.46DocScrutinizer05well, ok LiFePo

16:47.03sixwheeledbeastYes, Lithium will always provide more power per kilo, lithium atoms are smaller than lead.
16:48.43L29AhWizzup: SUP
16:49.21L29AhLiFePo is 50% lighter than lead
16:49.32L29Ahand 2,5 heavier than LiIon
16:49.49DocScrutinizer05hehe yes. anyway see how they "cheat" on last one I linked: "Pb Eq(uals): 7.9ah"  but "25.6Wh"
16:50.04DocScrutinizer05which in my book makes slightly over 2Ah
16:50.43DocScrutinizer05L29Ah: ack, many thanks for clearing it
16:51.08L29Ahalso lifepo can give away a lot more power, like 300C
16:51.26L29Ahawesome for starting a car using a tiny cheap immortal cell
16:51.26DocScrutinizer05:nod: that's why they may 'cheat' like this
16:52.33sixwheeledbeastis waiting for a Hydrogen Fuel Cell the size of BL-5J
16:52.44DocScrutinizer052Ah * 300C = 600A

16:53.23DocScrutinizer05sixwheeledbeast: I wish they finally would come to market with one of the several prototypes they had during last maybe 10 years
16:53.40sixwheeledbeastMay even get a years charge out of it.
16:54.02L29Ahnah they're not that energy dense
16:54.25sixwheeledbeastassumes oil companies have jumped on the tech and won't let go.
16:54.26DocScrutinizer05the benefit is: refuel them with e.g. ethanol
16:54.28L29Ahthey're like 10x of the state-of-art LiIon
16:54.52KotCzarnyl29ah, but much much more reusable
16:54.56DocScrutinizer05(not the hydrogen ones)
16:55.11L29AhKotCzarny: afair the prototypes have problems with longevity
16:55.49L29Ahalso storing hydrogen is not a simple task
16:56.07KotCzarnyL29Ah: that's why they are prototypes and not market ready products
16:56.19L29Ahit will permeate everything if it's not chemically bound
16:56.57sixwheeledbeastStore as water?
16:59.24DocScrutinizer05use hydrocarbon e.g. ethanol or methanol
16:59.36L29Ahsixwheeledbeast: and you have a perpetuum mobile
17:00.05KotCzarnythere are no perpetuum mobiles in this universe
17:00.05L29Ahit takes more energy to break water down than to burn hydrogen in a fuel cell
17:00.11DocScrutinizer05it's quite wasteful since the carbon is oxidized and just creates heat for nothing, but it somewhat works nicely, particularly for "storing hydrogen"
17:01.28sixwheeledbeastNot as efficient as hydrogen granted. hydrocarbon would be like going back 30 years

17:03.27KotCzarny'my car didnt start today. why? someone drank my battery to the bottom' :P
17:04.10sixwheeledbeastWell at least they couldn't steal it
17:04.11WizzupL29Ah: you poked me for a reason?
17:05.07L29AhWizzup: yes, you forgot about your plans to make plans and i wonder how are you and whether i should expect you to do that
17:05.30KotCzarnyl29ah: he got new toy
17:05.31WizzupYou've seen the maemo thread, right?
17:05.38WizzupKotCzarny: I ... what?
17:05.47KotCzarnywizzup, a33 tablet
17:05.54WizzupL29Ah: That's ... part of the whole plan :)
17:06.04KotCzarnyor i've confused the people
17:06.05WizzupI specifically got the tablet for this
17:06.08L29Ahhttp://ultracell-llc.com/store.php what
17:06.30L29AhWizzup: i've seen the "organized" thread; what thread are you talking about?
17:06.34WizzupL29Ah: I also got a few tablets for devuan people in amsterdam
17:06.45WizzupL29Ah: the organised thread also asked for people who want to help to specifically say that
17:06.53Wizzupso far I haven't seen anyone else say that they want to pick up any tasks
17:07.06L29Ahi don't really get why do you want to stick to the tablets
17:07.14WizzupI don't
17:07.19KotCzarnytablets are easy to do dev on
17:07.19L29Ahas they have a lot of problems on they own

17:07.38L29Ahqemu-user is easy to do dev on
17:07.40WizzupThe next two main things are: 1) start autobuilding packages for devuan, 2) get an image that we can run on some devices for testing
17:07.49KotCzarnyqemu-user doesnt do touch on display
17:07.53Wizzupand I think I also mention VMs in that thread
17:08.26L29Ahk i guess i suck and should buy another n900 to be of any use
17:08.35Wizzuphow so?
17:08.40WizzupI don't think that's true
17:08.51sixwheeledbeasthttp://www.myfcpower.com/collections/shop/products/myfc-powertrekk-2-0
17:08.52L29Ahi don't know debian and i don't want to be offline on my main n900
17:08.54L29Ahfor long
17:09.08WizzupL29Ah: you can use qemu-arm for most/all of that, correc
17:09.10KotCzarnyl29ah, grab a33 tablet, they go very cheap
17:09.10Wizzupt
17:09.14KotCzarnyeven cheaper than use n900
17:09.21WizzupL29Ah: I also don't ``know'' debian
17:09.26Wizzupbut how hard can it be :)
17:09.36KotCzarnywizzup: dpkg is hell
17:09.42Wizzup(finishing what I wanted to say) ... it's been about two weeks since any status update I think, because I got _completely_ flooded with work, been working till deep in the night every day
17:09.52WizzupKotCzarny: devuan has pretty nice auto build systems
17:10.03L29AhKotCzarny: cheaper than $30?
17:10.05Wizzupand most of the packages fmg and others have on github already have scripts to build it
17:10.23KotCzarnyl29ah, something in that range
17:11.10WizzupL29Ah: I think there's a few reasons we took some of these tablets -- more ram, still similar (relatively small screen), same instruction set, and the realisation to also move beyond the n900 at some point
17:11.17Wizzupthat doesn't mean not also making verything work on the n900

17:15.28WizzupL29Ah: anyhow, when I get home in a few days I will be more relaxed, right now I can mostly think of work
17:15.34Wizzuptoo much crap to do :/
17:15.54Wizzupif you want to start _now_ I can send you info that devuan folks gave me when I asked about auto building
17:16.11WizzupThey have a nice system, and we'll need git(lab) accounts and some ci hooks to get things going
17:16.21WizzupAnd then we're very close to just getting a repo where it gets auto build into
17:18.29WizzupL29Ah: but I do need to know what you're interested in, or what you'd like to pick up
17:19.02L29Ahare you talking about automatic image builds?
17:19.51Wizzupnot images, but repos
17:19.54Wizzupdebian repos
17:20.09Wizzupso you can add a repo to apt sources and it'll get our maemo-specific packages in there

17:21.22L29Ahi guess i have a messed up dependency graph in my head
17:23.51WizzupL29Ah: so the maemo specific things are being ported over to 'mainline' sw, e.g. gtk3
17:23.58Wizzupwhere we do not require specific patches to said sw
17:24.01L29Ahhttp://www.myfcpower.com/collections/shop/products/myfc-powertrekk-pucks this SUCKS
17:24.07L29Ahi can have 10W*h in a 18650 weighing 45g
17:24.13L29Ahand it's cheap and rechargeable
17:30.10DocScrutinizer05hmm while http://www.myfcpower.com/collections/shop/products/myfc-powertrekk-2-0 leaves me totally puzzled, it also gives me ideas along using a Peltier with arbitrary heat sources like handwarmer pocket ovens, heat pads, parabolic mirror, even medical products that heat from oxidizing some iron dust or whatever
17:31.45DocScrutinizer05http://www.thermacare.com/
17:31.47L29Ahpeltier is 1% efficient
17:31.51L29Ahand bulky as hell
17:32.12L29Ahas you need to enclose your heat source to get all the energy
17:32.24L29Ahalso you need to be careful not to overheat it
17:32.36L29Ahand at the same time you need to heat it more for better efficiency
17:32.47DocScrutinizer05ugh really? 1% only?
17:32.54L29Ahsmth like that
17:33.38DocScrutinizer05hard to believe they'd use such poor efficiency item in cooling boxes for 12V car / camping operation
17:33.38L29Ahstirling engines are a lot more efficient but are very expensive and not that good at longevity on small scales
17:34.22L29Ahthey're like 5x less efficient at cooling than traditional compressor setups you can see in fridges afair
17:34.23DocScrutinizer05or is the efficiency vastly asymmetric?
17:34.26L29Ahbut they come in simple and small packages
17:34.49L29Ahwell, you can't really compare cooling efficiency and the power generating one

21:49.02Vajbhmm maybe i'll give it a go
21:49.39Vajbwould be nice to have one program less open since telegram-purple can't be minimized to tray
21:50.02OksanaaNo /me or /commands, though. But joining a chat room or sending private messages is possible ; just, while one IRC user can be added to abook, chat room is not as intuitive.
21:50.41Vajbhmm maybe they could be implemented?
21:51.51OksanaaLike, I can add Vajb to Contacts, I cannot add #maemo to contacts. And actually, I am more frustrated with its handling of multiple IRC servers; when adding Vajb to Contacts, I cannot specify that it's on Freenode.
21:54.45OksanaaYes, I think that improvements could be made :-)  Like, there is no Reconnect button for an IRC connection, nor does it reliably automatically reconnect, hence I press many buttons to reconnect manually, on a daily basis. But that may be just my WiFi.
21:55.42Vajbhmm that multiple server flaw is kind of turn of to me tho
21:56.07Vajbsince irssi does that very well
21:57.25OksanaaIf you speak with the same people and the same channels all the time, you can easily return to them from Conversations window, without any multiple server problems.
21:58.43OksanaaJust, jumping from Contacts to IRC will mean choosing the server for the Contact all the time, since abook doesn't know on which server the person is.
21:59.08Vajbi see
21:59.34Vajbso maybe adressbokk needs a field for that
22:00.37OksanaaYes, addressbook may need something like name@server or something.
22:01.02Vajboh well enough of making smart comments of features i can't implement. Better for me to go to sleep :)
22:01.24OksanaaI can understand this "select a server" for SIP since SIP allows for cross-server speaking. But IRC isn't cross-server
22:13.43ff_have anyone seen "HWRecoveryResetSGX: SGX Hardware Recovery triggered" in dmesg on n900?
22:16.22ff_after reflash system and recover configurations this problem appears here
22:17.43OksanaaDoes it look like https://bugs.maemo.org/show_bug.cgi?id=9150 ?
22:17.50povbot_04Bug 9150: Device doesn't respond via UI. syslog reports HWRecoveryResetSGX: SGX Hardware Recovery triggered, sgx_misr eating all CPU
22:18.30ff_kernel module pvrsrvkm is faul or is Xorg problem?
22:18.47ff_yes, that bug
22:19.52OksanaaNot responding via UI... Is it possible to ssh into it and restart UI? Does it solve the freeze?
22:20.34ff_before reflash phone works fine for weeks
22:21.36ff_simple script can detect this state and automatically reboot but this is quite poor solution
22:22.42OksanaaNot reboot. Killall hildon-desktop, rather
22:22.53OksanaaIf it helps ^
22:22.56ff_after reflash & recover this bug appears in two, three days
22:24.01OksanaaI have met this bug long ago, but I am not an expert on it. Also, I rarely reflash; broken charging port
22:25.08ff_killall hildon-desktop probably will reboot, but I check it
22:25.34OksanaaNot as root! Just as user
22:26.11OksanaaIf done as user, the device will not reboot. GUI will hopefully be restarted and unfrozen.
22:26.55OksanaaAnd don't repeat it many times in a row, watchdog will not like it ( and hence, will reboot )
22:28.29ff_ok, so I check it now, wait a minute
22:32.00*** join/#maemo ff__ (531dada0@gateway/web/freenode/ip.83.29.173.160)
22:32.41ff__as user rebooted too
22:35.12OksanaaWeird. I do killall hildon-desktop as user all the time, along with killall hildon-home and killall hildon-status-menu
22:38.03ff__maybe some system modification makes differ
22:40.20ff__I change stock kernel to kernel power and I did some other memory optimalization
22:40.57ff__it has only 256MB
22:41.55OksanaaKernel-power 2.6.28-10power52 over here, on CSSU thumb
22:42.31OksanaaNo idea about memory optimizations
22:44.55DocScrutinizer51other optimizations?
22:45.04ff__I throw webbrowser, modest, image-viewer, tracker out of memory, maybe that makes differ

22:45.08infoboti heard speedpatch is http://talk.maemo.org/showthread.php?p=1012405#post1012405 >>first i don't realy understand what does this patch do (that is why it is called miracle patch)<< [/quote original-author-of-speedpatch], or http://talk.maemo.org/showpost.php?p=1328060&postcount=3325 [bug report]
22:45.35ff__I don't use speedpatch
22:45.51DocScrutinizer51good
22:47.22ff__probably it's hardware issue, couse it's appear in other devices with this SGX powerVR thing
22:47.42ff__It is possible to dissable powerVR during boot time?
22:48.05ff__I don't use it also
22:50.24OksanaaIs it one of modules in /etc/mce/mce.ini ?
22:51.51ff__in mce.ini I've Modules=display;keypad;vibrator;led;battery;filter-brightness-als;inactivity;alarm;accelerometer;callstate;camera; homekey;audiorouting
22:52.46OksanaaSounds same. What does SGX do?
22:53.21ff__powervr seems to be part of display module in mce.ini
22:53.56OksanaaOkay, but switching off entire display would be... Unwise.
22:54.08*** join/#maemo Sigyn (sigyn@freenode/utility-bot/sigyn)
22:54.09ff__SGX is graphic accelerator
22:55.09ff__Xorg use it for some 2D acceleration, and games for 3D acceleration
22:56.00OksanaaThere is /etc/powervr.ini ?
22:56.10ff__yes
22:57.36ff__SGX fault appears no matter of ForceExternalZBuffer value
22:59.49OksanaaAnd /etc/udev/rules.d/10-pvrsrvkm.rules No idea what's the soft and proper way to disable SGX PowerVR from being loaded at startup
23:00.08ff__command "lsof | grep pvr" give two libs: libpvrPVR2D_DRI2WSEGL.so libpvr2d.so , maybe one of them make error
23:00.41ff__me too :(
23:04.12ff__Xorg use 2D acceleration, this libs has 2D in name...
23:04.36ff__do you know if that bug appears with stock kernel?
23:05.43OksanaaI expect it does. First time I encountered this bug it was a pretty vanilla installation, not thumb, and probably not kernel-power. But, it was a long time ago, so not sure.
23:11.34*** join/#maemo auenfx4 (David@DC-50-235.bpb.bigpond.com)
23:13.52Oksanaaff__ : consider asking at #powervr ?
23:15.20ff__what's that, I'm nooby, it's another room in freenode?
23:23.23OksanaaYes :-)  Probably not many people, though
23:23.53Oksanaahttp://powervr.gnu.org.ve/doku.php
23:24.59DocScrutinizer05powerVR is the GFX accel with the nasty closed blob firmware
23:26.47ff__it's possible to disable it at all?
23:27.11DocScrutinizer05I'm not sure how to tell Xserver to not use GFX accel
23:27.43DocScrutinizer05it *should* work except for some nifty overlay stuff like in mediaplayer-video
23:28.00DocScrutinizer05also possibly all screens status menu is an overlay
23:28.16ff__thx Oksanaa, I'm checking it
23:28.59DocScrutinizer05it _is_ possibly to run a system without SGX PVR, but *maemo* might need some patches to actually work without it
23:32.16freemangordonno way if you want hildon-desktop
23:33.09DocScrutinizer05http://omappedia.org/wiki/Graphics#SGX_software_components  http://listas.gnu.org.ve/pipermail/powervr-devel/2012-September/000036.html  http://powervr.gnu.org.ve/doku.php  https://pandorawiki.org/SGX_drivers
23:33.38freemangordonff__: that segfault could be caused by a corrupt .pvr image
23:33.54ff__patches for kernel module or for graphic system?
23:33.57DocScrutinizer05indeed, or merely by hw waer&tear
23:34.06freemangordonthose are "screenshots" of applications
23:35.06DocScrutinizer05hmm, I guess I miss some 'hidden' posts
23:36.14DocScrutinizer05PVR drivers / firmware notorious to 'segfailt'

23:37.45DocScrutinizer05freemangordon: (no way if you want hildon-desktop) isn't that just for the silly wallpaper animation during sliding desktop screens?
23:38.27DocScrutinizer05IOW setting parallax=0 would make it dispensable
23:40.06ff__indeed, it might be corrupt .pvr, because this problem intensify after I reflash & recover some configs
23:40.08*** join/#maemo cyphase (~cyphase@unaffiliated/cyphase)
23:40.10OksanaaDoes hildon-status-menu menu need it for overlay? Do mediaplayer-video and camera-ui need it, too?
23:40.39DocScrutinizer05Oksanaa: I guess: yes, yes and yes
23:40.50OksanaaWhere to find not-corrupt .pvr? And how to put it into place?
23:40.55DocScrutinizer05while ""need""
23:41.43DocScrutinizer05also I think PVR 2D is FOSS, only 3D is blob
23:42.58DocScrutinizer05well, I dumped the essence of all my knowledge with those 4 links I quoted above
23:43.04DocScrutinizer05see for yourself
23:43.34ff__ok thx
23:43.42DocScrutinizer05just one missing factoid: I always hear "compositor" mentioned in context of PVR
23:44.42DocScrutinizer05I *guess* it's about https://en.wikipedia.org/wiki/Compositing_window_manager
23:46.40ff__and parallax=0 in witch file? I was thinking of transition.ini but ther is no parallax var
23:47.20OksanaaRead about modified hildon-desktop, or something
23:48.05OksanaaSome features are not immediately obvious.
