nicksydney_Happy New Year all !00:00
nicksydney_seeems like wpwrak new year is not good without power 07:56
nicksydney_DocScrutinizer05: Happy New Year...hope 2014 Neo900 break record and mass production can start :)07:56
nicksydney_has anybody used one of this before http://www.banggood.com/USB-Saleae-24M-8CH-24MHz-8Channel-Logic-Analyzer-Latest-Support-1_1_15-p-74101.html?utm_design=13&utm_source=emarsys&utm_medium=mailad124_Other&utm_campaign=newsletter-emarsys&utm_content=vera&emst=ru2dB7U2Gt_34813_776877_18 ?07:58
apeleteHappy New Year everyone !08:21
DocScrutinizer05nicksydney_: thanks12:39
DocScrutinizer05again happy new year to everybody12:40
DocScrutinizer05somebody familiar with fail2ban? any hints how to set it up?12:40
kyaki'm using pam-abl and some time-based rules for iptables15:52

whitequarknicksydney_: saleae's software is quite great17:07
wpwrakwait ... still booting .. :)17:08
wpwrakah yes, heard of that one.17:10
wpwrak(i think) it's the one with a pcb with something like ten buttons, isn't it ?17:10
wpwrakrev B with OLED .. all paths lead to rome ;-)17:10
wpwrakDocScrutinizer05: (left) yeah, some short blackout, it seems.17:17
wpwrakas usual, it took only the pc down (well, and probably the fluke, which always resets when there's even the slightest problem with power)17:18
wpwrakwow, 30c3 had 9k people. bigger than FISL.17:22
wpwrakthe free software conference in porto alegre, brazil18:35
wpwrakit's pretty huge but the peak so far was "only" some ~8500 people18:36
eintopfwpwrak_: welcome back :)20:20
eintopfit was a netsplit only20:21
wpwrak_yeah, for once the problem wasn't on my end :)20:25
DocScrutinizer05yeah, netsplits20:55
nicksydney_wpwrak_: welcome amigo ! ... power down start of 2014 ?21:24
nicksydney_wpwrak_: looks like anelok vs http://hackaday.com/2014/01/01/usbpass-a-mooltipass-like-project/ and anelok is the beautiful version i suppose :)22:31
DocScrutinizer05what problems do those guys have? writing all [names] with [ ] around them22:51
DocScrutinizer05this really looks silly and retarded22:52
nicksydneywpwrak_: was thinking last night while looking at anelok ... what if we add a vibrating motor to indicate low battery...or perhaps a small current LED23:35
kristianpaulblink led, motor good for battery get discharged23:39
wpwrak_no room for a motor :) and there is already a led. could be used for something like this ... but: anything that draws more current to indicate a low battery is likely to make the system fall over even more quickly.23:41
wpwrak_a more power-efficient way would be to indicate "BAT" in the corner of the OLED. that draws less power than turning on the LED.23:41
kristianpaul(oled) oh interesting23:45
whitequarkwpwrak_: you can blink the led with very low duty cycle23:46
whitequarkturn it on for 200ms once a five second interval23:46
whitequarkadditionally that draws more attention23:46
kristianpauland power23:47
whitequarkversus oled? not sure23:48
wpwrak_whitequark: already about 10 ms should create a visible flash. but the peak current will still be much larger than the OLED.23:49
whitequarkjudging by peak current, we have thermonuclear synthesis23:49
whitequarkhow much current would "BAT" on OLED draw?23:50
whitequarksay... 100 pixels?23:50
wpwrak_something like 2-3 mA, i think. maybe even less.23:51
kristianpauland when wpwrak_ using fram anelok just will power from air :)23:51
whitequarka rather bright LED draws 10mA23:52
whitequarkso... 10mA for 10ms/5s, or 2-3mA continously?23:52
whitequarkseems obvious to me23:52
whitequarkeven if it's 100mA (uber bright!) the flashing technique still wins23:53
wpwrak_on terms of Ah, yes. but the peak will translate to a further drop of battery power, possibly driving the system into reset.23:55
