07:36.09xesone little issue with cssu clock-ui: if while i'm using the phone the alarm dialog appears and i'm so quick stopping it before the audio alarm tone starts (probably the phone is a bit lagging)... once closed the dialog the tone starts and it's impossible to stop it

08:25.05DocScrutinizer05LOL
08:25.56DocScrutinizer05the joy of an immanently async design like dbus, I guess
08:28.51DocScrutinizer05with something like dbus, you _never_ should implement state machines that transition on a signal and have no way to resync when a single signal gets lost
08:30.16DocScrutinizer05iow each such design should use "keep alive" or similar techniques, and reset to sane state when those are missing
08:30.39xesyeah, it's a stupid issue but very annoying when my son is sleeping near me
08:31.23DocScrutinizer05yeah, alas the bugs system designers and sw devels introduce are not selected for convenience in real life :-)
08:32.35DocScrutinizer05I never really liked the way dbus gets used for $everything on deskops and on maemo, without proper transmission security layer
08:33.32DocScrutinizer05it's sort of like UDP-only internet
08:33.55xesi know it's a problem hard to imagine but our "always lagging device" is a beast producing unexpected beahaviors ;)
08:35.06DocScrutinizer05yep
08:35.37DocScrutinizer05not a single dbus-dependent program I've seen actually takes care to recover from "packet loss" on dbus
08:35.57DocScrutinizer05FSO maybe a nice exception

10:39.49jon_yhow do you even loose a packet on dbus?
10:40.26jon_ydbus probably reinvents unix sockets
10:53.13DocScrutinizer05dbus easily can 'lose' packets, when e.g. receiver doesn't really listen to signals
10:53.48DocScrutinizer05even messages are not warranted to get delivered to receiver when you use async
10:54.24DocScrutinizer05most dbus API usage is just fire&forget
10:55.08DocScrutinizer05you *could* check for reply etc, but that's not mandatory and I know many apps don't care

13:13.22drathirlol /me again have issue with wifi signal...
13:14.58drathirwonder if that could be in any way connected with app genwall...
13:16.27drathirfew meters from router signal is weak 5-10m from router no signal at all...
13:17.41SiceloWeb<PROTECTED>
13:33.22DocScrutinizer05poor signals *quality* doesn't necessarily mean poor signal *strength* - could also be interference
13:34.03DocScrutinizer05what you see in wifi connecting apps is usually quality, not strength
13:35.59DocScrutinizer05and no, if genwall is a firewall then this should be unrelated
13:37.04DocScrutinizer05suggests wifieye
13:38.28drathirSiceloWeb: DocScrutinizer05 in past was the same behaviours no idea whats goin repaired by own... sniffed area no diff in noise...
13:39.36DocScrutinizer05use wifieye to check for other APs that interfere. Make sure you got no other strong TX like BT or microwave oven nearby
13:40.03DocScrutinizer05note that neither BT nor microwave show up in wifieye
13:40.38drathirDocScrutinizer05: the wifieye 2m see max 10% quality...
13:41.00DocScrutinizer05and actually even what WLAN chipsets declare as signal strength is massively depending on signal quality aka interference too
13:41.31DocScrutinizer05wifieye does show signal strength, not quality
13:41.34drathiraircrack checked area no diff in range...
13:41.41DocScrutinizer05afaik. But... see above
13:41.54DocScrutinizer05sorry you lost me
13:42.11DocScrutinizer05aircrack will not change range
13:43.19DocScrutinizer05all that aircrack and wifieye really can tell you is: are there other APs on same channel or channel nearby, so they would interfere
13:43.26drathirDocScrutinizer05: i checkin from local prepared hw intended to that things...
13:43.38drathirthe aircrack i mean...
13:43.53DocScrutinizer05I still don't get it
13:44.02drathirno more noise/traffic than usual in area...
13:44.15DocScrutinizer05checking won't improve your range, no matter what you use for checking
13:44.31drathirn900 is 2meters from router anyway...
13:44.40DocScrutinizer05then it's maybe noise you don't see, I.E. no WLAN noise
13:45.24drathirDocScrutinizer05: aircrack in monitor mode see also not connected messing stations too and their signal...
13:45.24DocScrutinizer05well, sorry I can't tell more than what I already did
13:46.02drathiri will diggin, bc honestly wonder with what that is connected ;p
13:46.32drathirat least its pretty funny behaviour...
13:47.52DocScrutinizer05seen all WLAN in 50m radius going down when a nasty microwave operated
13:48.04drathirfor wifi modules are wl12xx and mac80211 correct?
13:50.22DocScrutinizer05and there are even industries tempering screws etc with 2.4GHz
13:50.24drathirDocScrutinizer05: yea im in pretty "hole" area with distance from similar to microwave sources but correct is a fair funny thing takin down signal quality all devices in area...
13:52.06DocScrutinizer05when it's a problem of N900 only (needs check against other clients on same AP), then you might have problems with wifi antenna in device, might need contacts cleaning
13:53.08DocScrutinizer05or collision with N900's BT and coexistence
13:53.20DocScrutinizer05only when BT enabled and active
13:54.20DocScrutinizer05when a battery removal fixes the issue, it might be a problem in WLAN chip's firmware and config that got messed up in WLAN chip's RAM

14:08.16drathirDocScrutinizer05: bf i cleaned gen wall settings i even dont see status indicator of gsm/wifi at all ;p
14:08.29drathirbefore*
14:17.45SiceloWebmaybe you should just use iptables :)
14:17.50drathirits possible that driver wil not follow 100mW and drop down to 10mW in n900?
14:19.22DocScrutinizer05this is not cssu related and no, 10mW is unrelated to poor AP signal quality at N900 end
14:24.28*** join/#maemo-ssu NishanthMenon (~nmenon@unaffiliated/nishanthmenon)
14:25.58drathirin theory a little yes related bc looks like reciving is so much throtle down that n900 have a problems with comunication... even in biggest noise and w/o antenna i should be able connect device lying at router... but correct that probably isnt connected with cssu... thans a lot for ideas and have a good day...
