DocScrutinizer | yeah, there's a new better codec every other week | 02:40 |
DocScrutinizer | the 2400 figure is straight from my a... though.

TiagoTiago | I was writting this long elaborated post on a forum with microB, then the "battery low" banner popped so i pulled the charger cable and plugged it in, it said charging so i went back to writting, next thing i know another banner pops saying "recharge the battery" and the fucking thing shuts down | 03:05 |

DocScrutinizer | cehteh: and, isn't it the truth? | 03:33 |
cehteh | dunno if its the truth but looks better | 03:33 |
cehteh | while some 'legend' about the abbrevitations or some -h flag for human readable might be useful | 03:34 |
cehteh | (maybe i shall look at that script) | 03:34 |
cehteh | uhm .. since 2.6.38 my terminals under x behave strangely .. both xterm and rxvt | 03:35 |
TiagoTiago | Wait, is that the status of the battery or the properties of the juice flowing thru the usb port? | 03:35 |
cehteh | mhm maybe its my windowmanager | 03:36 |
DocScrutinizer | interesing are TimeToFull(min), TimeToEmpty(min), RSOC/CSOC=%charge, NAC=capacity(mAh), CACD,CACT=corrected values of NAC, for current/temperature | 03:38 |
DocScrutinizer | especially important: CI:0 (Calculation Invalid) | 03:40 |
TiagoTiago | what should those read if the charger juice is flowing as it should? | 03:40 |
DocScrutinizer | which those? | 03:41 |
TiagoTiago | the values bq and/or reports that are relevant to juice health | 03:41 |
DocScrutinizer | sorry, doesn't parse | 03:42 |
TiagoTiago | I asked how to read the current properties of the juice comming in thru the USB port and you suggested lshal and that bq script | 03:43 |
DocScrutinizer | I did not | 03:43 |
TiagoTiago | I'm confused | 03:43 |
DocScrutinizer | there is no way to measure the current drawn from USB | 03:44 |
*** trbs has quit IRC | 03:44 | |
DocScrutinizer | directly | 03:44 |
TiagoTiago | How does it know when there is not enough juice coming in like when doing heavy stuff while plugged to a PC? | 03:45 |
DocScrutinizer | you can measure the current flowing to/from battery, with `bq27200.sh 5` and compare the mA reading for USB plugged/unplugged. They will roughly differ the size of current fed to system from USB | 03:45 |

DocScrutinizer | not enough current (my jiuce is in the fridge!) == batery current is discharging battery, not charging it | 03:46 |
SpeedEvil | Oh. | 03:48 |
TiagoTiago | So it can tell the amount of current flowing to/from the battery and which way it is flowing? | 03:48 |
SpeedEvil | One random point on 'my USB is broken' | 03:48 |
SpeedEvil | Random objects can get into your USB port | 03:48 |
DocScrutinizer | TiagoTiago: yes, that's what bq27200(.sh) is for | 03:48 |

DocScrutinizer | TiagoTiago: just look at it? | 03:49 |
TiagoTiago | k | 03:49 |
TiagoTiago | the voltage value doesn't go negative, what gives? | 03:51 |
DocScrutinizer | or study this: http://wiki.maemo.org/User:Joerg_rw/jrbme/bme_chargefloat_log | 03:51 |
DocScrutinizer | TiagoTiago: your sentences always decode like googletranslates of chinese | 03:51 |
TiagoTiago | really? | 03:52 |
DocScrutinizer | well, not actually, you at least use correct punctuation marks like ? after what | 03:53 |
TiagoTiago | There is a mV in that loop mode report, but unlike the mA its value doesn't go negative when i pull the charger plug out | 03:53 |
DocScrutinizer | well, that's the voltage of battery. Do you really expect it to reverse polarity? | 03:54 |
TiagoTiago | What is the explanation for that? | 03:54 |
TiagoTiago | i thought it was of the flow between the device and battery | 03:54 |
SpeedEvil | No. mV is the battery voltage | 03:55 |
DocScrutinizer | voltage of the flow?? | 03:55 |
SpeedEvil | It's always positive. | 03:55 |
DocScrutinizer | flow is Ampere, it has no voltage | 03:55 |
* SpeedEvil drops Mr Ampere on TiagoTiago | 03:55 | |
TiagoTiago | I thought that when electricity went the opposite way the numbers would be negated | 03:56 |
DocScrutinizer | I made up my mind, it sounds japanese. "we stopped pump fill sea water on PV. Why pressure in PV it is positive?" | 03:57 |
*** Pavel has joined #maemo | 03:58 | |
TiagoTiago | Watts = Volts * Amps , Watts stay positive regardless of the direction of the flow, so Amps and Volts need to always have the same sign | 03:58 |
DocScrutinizer | BS | 03:58 |
TiagoTiago | Are you saying people do use negative watts when talking about electricity? | 03:59 |
DocScrutinizer | sure | 03:59 |
*** Malin_ has quit IRC | 04:01 | |
DocScrutinizer | a water power plant delivers 5MW with water coming down from upper pond. To pump water back up during nighttime you of course can speak of negative Watts that the power plant's trubines EAT instead of delivering it | 04:01 |
DocScrutinizer | pretty identical situation on battery charging or depleting | 04:02 |
TiagoTiago | What is the difference between 3V -10mA and -3V 10mA ? | 04:03 |
DocScrutinizer | honestly, this is so silly I'm not sure if it's really nifty trolling | 04:03 |
villager | TiagoTiago: one difference would be reversed polarity => fried device? | 04:04 |
TiagoTiago | No, i'm really trying to understand how things really work since i my previious understanding is being contradicted | 04:04 |
TiagoTiago | How are those two things not the same thing? | 04:05 |
TiagoTiago | I always thought Watts was an absolute value, a scalar, but now you're saying it can be negative... | 04:06 |
villager | voltage and current aren't the same thing, for starters | 04:06 |
villager | watts is measured in a particular direction, just like current... if the energy flows in the opposite direction, it becomes negative | 04:08 |
DocScrutinizer | while Voltage is like pressure (of a tank e.g), current is the flow of some medium (e.g. in / out of a pipe to that tank) | 04:08 |
TiagoTiago | Are you saying that if someone wires one of those wall adapters that measure power consumption backwards it will read megative watts being consumed? | 04:08 |
*** lcuk2 has joined #maemo | 04:08 | |
villager | TiagoTiago: in theory, it should. | 04:09 |
DocScrutinizer | Voltage=force, current=volume/distance | 04:10 |
villager | of course the electronics may not be designed for that... | 04:10 |
DocScrutinizer | Voltage=force, current=volume/distance per time unit | 04:10 |
villager | TiagoTiago: if you have a solar panel on your roof and pump electricity *into* the power grid instead of out, you get negative watt consumption and the power company pays you, if they allow that kind of thing | 04:11 |
TiagoTiago | Voltage is like pressure difference, Amperage is like flowrate; how is it possible for it to flow backwards accross the pressure gradient? | 04:11 |
DocScrutinizer | if you got a garden hose, the voltage is the pressure in PSI/ATM, and the current is the liters/s that are running thru it | 04:11 |

villager | TiagoTiago: I think you just need an even higher voltage from the charger, then the current will flow into the battery without changing the battery's voltage | 04:14 |
DocScrutinizer | volzage is like pressure difference (I got 1024 mBar here, pressure difference between athmosphere and that vacuum part of the mercury glass tube), how comes there's still water flowing OUT of the tap? | 04:16 |

*** Roksteady has joined #maemo | 04:17 | |
*** philipl has quit IRC | 04:17 | |
DocScrutinizer | simple answer: pressure of water in the pipe is even higher than those 1024mBar | 04:17 |
TiagoTiago | Ok, consider two water boxes connected by a hose at the bottom, if the two boxes are on the same level Voltage and Amperage are at zero, now if you raise box A, or manually put more water in it, or activate a pump the hose is going thru so that it pumps water to box B, Voltage and Amperage are positive ( we will keep using box A as reference), if you do it the other way around V and A would be negative; how the hell would make one be posit | 04:18 |
TiagoTiago | ive but the other negative? | 04:18 |
*** vblazquez has quit IRC | 04:19 | |
*** dashavoo has quit IRC | 04:19 | |
*** dashavoo has joined #maemo | 04:19 | |
DocScrutinizer | both boxes have positive Voltage/pressure, you easily can test when you drill a hole into bottom: water comes out with the pressure of that particular box | 04:19 |
TiagoTiago | Not relative to each other | 04:20 |
DocScrutinizer | just when you fill in water in one, then the pressure is higher than in the other, so there's a "voltage" across your tube | 04:20 |
villager | TiagoTiago: the battery voltage is the pressure difference between the top and bottom of *one* box, say B, not the pressure difference between box A and B... easy | 04:20 |
villager | TiagoTiago: then the voltage is always positive, regardless of current | 04:21 |
*** vblazquez has joined #maemo | 04:21 | |
villager | TiagoTiago: then if you're discharging, box A is lower, if you're charging, box A is higher | 04:21 |
villager | the battery voltage will depend on how much water is in box B, but not the direction of the flow | 04:22 |
*** bef0rd has joined #maemo | 04:24 | |

DocScrutinizer | (except if you're interested how much voltage drop error your Amperemeter introduces to the circuit under test) | 04:26 |

DocScrutinizer | real world is rarely ideal (except with supraconductors) | 04:28 |
DocScrutinizer | but for a basic understanding of physics you better assume it was, first approach | 04:28 |
*** radic_ is now known as radic | 04:29 | |
DocScrutinizer | pretty much same way you assume the water pressure in your tapwater pipe is same before and after meter | 04:29 |
DocScrutinizer | the meter is counting the current. Well actually it integrates the current over time, and reads a volume spent | 04:31 |
DocScrutinizer | you can tell the current by watching how fast the dials spin | 04:31 |
DocScrutinizer | that's Ampere | 04:31 |
DocScrutinizer | the pressure might be high at nighttime, and rather low when every neighbour waters their lawn. But usually it doesn't become negative (as pressure of a battery never does) | 04:33 |
*** TiagoTiago has quit IRC | 04:33 | |
DocScrutinizer | still you might decide to pump water *into* your tap, by using a pump that has higher pressure than that found inside the pipe | 04:34 |
*** wmarone_ has quit IRC | 04:34 | |
DocScrutinizer | (beware, your neighbours probably will call homeland security!) | 04:35 |
DocScrutinizer | tough, if you got a wate tank on top of your roof, you for sure will pump water up (charge), and also water will come down again and flow out your tap (discharge). The pressure is the voltage, the liters/min is the current (Ampere) | 04:39 |

*** TiagoTiago has joined #maemo | 04:40 | |
TiagoTiago | sorry, the system locked up, lemme check the log to catch up | 04:40 |
DocScrutinizer | meh, too bad. Was about to elaborate about Spain where everybody got such a watertank on their roof, as central water supply is shaky. And "not enough power to charge" means the water flowing into N900 via USB is not as much as that you draw from the tap in the AV-receptacke... errr | 04:42 |
DocScrutinizer | s/draw/draft/? | 04:43 |
TiagoTiago | So the voltage is the voltage of one thing, while the current is the current of somthing else? | 04:43 |
DocScrutinizer | basically yes | 04:44 |
TiagoTiago | Why do they do it like that? | 04:44 |
DocScrutinizer | because there's no other meaningful way to do it | 04:45 |
villager | TiagoTiago: it's not physically possible to measure voltage and current on exactly the same thing... as said, voltage and current is different | 04:45 |
TiagoTiago | So it's like they put a pressure gage on the pipe but use a waterwheel under the faucet to measure current flow? | 04:46 |
villager | voltage is always between two points. current is not, it can be measured in a single point | 04:46 |
DocScrutinizer | TiagoTiago: I STRICTLY DISCOURRAGE to try and probe the Ampere found in a wall mains outlet. You can probe the Volt though | 04:46 |
*** NishanthMenon has joined #maemo | 04:47 | |
TiagoTiago | It's like measuring windspeed instead of the motion of the air atoms and molecules? | 04:48 |
DocScrutinizer | checking Ampere of a mains outlet is like bucket-measuring how many liters of water are in your waterpipe | 04:48 |
DocScrutinizer | depending on diameter of pipe this will become a rather unpleasant experience | 04:49 |
villager | fzzt! | 04:50 |
DocScrutinizer | like villager said. Current is the number of electrons passing by at ONE point / second. While Voltage is the difference of electron pressure between TWO points | 04:50 |
TiagoTiago | Usually you would measure how much current is flowing without makeing the current flow, like placing a waterwheel in a river instead of blasting open a riverbank | 04:50 |
villager | the ideal amperemeter is basically a shortcircuit, so a real bad idea to try on your power outlet | 04:50 |
timeless_w7ip | doc: you probably wnted 'drew' (also available in other cases is 'drawn') | 04:51 |
TiagoTiago | I thought you could measure Amps with some circuit sitting between the source and the device consuming the electricity.... | 04:51 |
DocScrutinizer | yes, you can | 04:52 |
villager | TiagoTiago: yes, and ideally that device has no resistance (which is why I said shortcircuit) | 04:52 |
timeless_w7ip | s/wnted/wanted/ | 04:52 |
infobot | timeless_w7ip meant: doc: you probably wanted 'drew' (also available in other cases is 'drawn') | 04:52 |
TiagoTiago | and that is the same way you could measure the Volts "entering" the device's circuit | 04:52 |
DocScrutinizer | but that's because of the way this equipment works. You also can test the magnetic field around one point of a wire, and that'S a very convenient way to probe current | 04:52 |
villager | TiagoTiago: the ideal voltmeter has infinite resistance, *no* current passes through it | 04:53 |
DocScrutinizer | like no water flows out a PSI meter | 04:53 |
TiagoTiago | but if you already got your voltmeter there why not use the same input and output for measuring current flow? | 04:53 |
villager | you cannot mix the two without disrupting the circuit | 04:54 |
TiagoTiago | even if the two are in parallel or being switched from one to the other and back very fast? | 04:54 |
DocScrutinizer | you can't plumb a water volume meter to the PSI-meter stub | 04:55 |
villager | and it would not be useful in any case, the current flowing through your voltmeter is not the current you want to measure, which is probably the current through the *rest* of the circuit | 04:56 |
DocScrutinizer | exactly | 04:56 |
DocScrutinizer | and you wouldn't want to cut the current to the rest of the circuit by inserting a virtually infinite resistance voltmeter at the point where your Amperemeter was | 04:57 |
TiagoTiago | Like my example with the pressure gage on the pipe, the pressure gage is a circuit with infinite (or really big) resistance between the pipe and the ground, then you add a little turbine thingy in the pipe between the faucet to measure current flow, why can't somthing like that be done with the electricity comming fromthe battery? | 04:57 |
DocScrutinizer | it is done like that, nevertheless logically the two things are unrelated | 04:58 |
DocScrutinizer | and disjunkt | 04:59 |
*** mlwane has quit IRC | 05:00 | |
TiagoTiago | If the faucet lead to a sealed room, if the room was pressurized to the point of having more pressure than the pipes, both the current and the pressure measured values on the pipe would be negative. | 05:03 |
villager | TiagoTiago: so you have a pressure gauge to measure pressure and turbine in tap to measure flow, that's different things, what makes that different from how it's done for battery, where volt and amps is also different? | 05:03 |
TiagoTiago | No, 'cause the values of the two always share the same sign | 05:04 |
villager | TiagoTiago: no, in the case of the pressurized room, the water pressure would be positive, and the flow would be negative | 05:04 |
TiagoTiago | But with the battery no the N900, in the loop mode of that bq script, volts and amps don't always share the same sign | 05:04 |
*** chx_afk is now known as chx | 05:05 | |
TiagoTiago | The pressure gage is measuring the pressure difference between inside the pipe and the rest of the room | 05:05 |
TiagoTiago | (forget what i said about ground) | 05:05 |
villager | uh huh, but that's not what the battery gauge measures | 05:06 |

*** Evanescence has quit IRC | 05:08 | |
*** Evanescence has joined #maemo | 05:08 | |
villager | the battery voltage measurement is more useful the way it is now, because it says how much power is left *inside* the battery, which is quite useful to know | 05:08 |
villager | besides it's not clear what else you'd want to measure | 05:08 |
TiagoTiago | There is no measure of the voltage difference between the battery and the device? | 05:09 |
DocScrutinizer | we're not interested in the voltage drop along the copper trace from battery to device | 05:09 |
DocScrutinizer | (well, not really) | 05:09 |
DocScrutinizer | it's supposed to be ~0 | 05:09 |
TiagoTiago | I just found it confusing that it reports volts and amps but not of the same thing, i was expecting it to provide values that could be used to calculate how many watts the device is sucking | 05:10 |
villager | you can | 05:10 |
* DocScrutinizer SIGHS | 05:10 | |
TiagoTiago | You can't calculate watts without knowing both the amps and the volts | 05:10 |
DocScrutinizer | going tru / and found across the device. You're not interested in the watts the copper trace is dissipating | 05:11 |
villager | you have both amps and volts... if you get negative watts, that means the device is charging the battery instead of draining it | 05:11 |
TiagoTiago | If they are from different things then it's like trying to calculate someone's bodymass index by using their height but their dog's weight | 05:11 |
DocScrutinizer | BS | 05:12 |

*** alextreme has quit IRC | 05:12 | |
TiagoTiago | Current can't flow against the voltage | 05:12 |
DocScrutinizer | voltage is between plus and minus, while current is either going into plus or coming out of minus | 05:13 |
villager | as said, if you're charging, the charger has a higher voltage than the battery, so current will flow into the battery | 05:13 |
TiagoTiago | unless your're measuring the voltage of somthing else instead of the circuit you're measuring the amperage | 05:13 |
villager | but the charger voltage is not measured here | 05:14 |
villager | just the battery voltage | 05:14 |
TiagoTiago | how can it be going to + without coming from - ? | 05:14 |
DocScrutinizer | I give up | 05:14 |
TiagoTiago | I'm sorry, this thing with measuring things a different way but still saying it as if it was the same is confusing me | 05:15 |
villager | current can come from anywhere it is forced into the circuit, like from the power grid... doesn't have to come from the battery you're charging. | 05:17 |
timeless_w7ip | tiago:: let's look at something else | 05:17 |
timeless_w7ip | consider temperature | 05:17 |
timeless_w7ip | let's have 3 rooms A .. B .. C | 05:17 |

timeless_w7ip | and the temperature in the next room (B) 30degrees | 05:17 |
timeless_w7ip | then at some point there's going to be a transfer of heat from C to B | 05:18 |
timeless_w7ip | it's going from a place with +++++ to a place with +++ | 05:18 |
timeless_w7ip | I could make A have a temperature of -10degrees | 05:18 |
timeless_w7ip | but it's still possible for things to go from +++++ to +++ instead of having to go to a place with - | 05:19 |
timeless_w7ip | does that make any sense? :) | 05:19 |
*** Evanescence has quit IRC | 05:20 | |
timeless_w7ip | btw, the use of + and - in electricity was actually arbitrary, it's now consistently used with + and - in a certain way | 05:20 |
timeless_w7ip | but it could have been the other way | 05:20 |
TiagoTiago | But when we talk about volts we mean difference and not absolute values | 05:21 |
*** Evanescence has joined #maemo | 05:22 | |
TiagoTiago | It turns out it is backwards, actual electrons flow from negative to positive, but they kept it reversed for backwards compatibility | 05:22 |
DocScrutinizer | TiagoTiago: I told you you can not measure device Watts by bq27200. It's a dedicated battery monitor hardware. It *only* shows _battery_ voltage (between + and - of battery) and battery current in/out. Device with all the consumers and charger is on the other end | 05:22 |
DocScrutinizer | the charger also can power the device consumers directly, then this part of current will not be seen by bq27200 | 05:24 |
TiagoTiago | So there is no direct way to measure watts consumption, we can onlyestimate it by watching the effects of that consumption? | 05:24 |
*** mikhas has quit IRC | 05:25 | |
villager | yes... if you remove the charger, then the two must be equal | 05:25 |
DocScrutinizer | as told way above, you can plug and unplug charger. The difference in battery current is what the device actually consumes | 05:25 |
DocScrutinizer | err, is what the charger supplies | 05:26 |
DocScrutinizer | current*volt of battery == current*volt of device sans charger, so this is a pretty accurate reading | 05:26 |
*** alextreme has joined #maemo | 05:27 | |

DocScrutinizer | negative watts do make as much sense as do negative voltages and currents | 05:35 |
TiagoTiago | unless you're mixing apples and oranges | 05:35 |
DocScrutinizer | TiagoTiago: you are mixing apples with oranges. We never said voltage is along the wire from battery to device | 05:36 |
DocScrutinizer | we actually always explained those two physical values are largely unrelated | 05:36 |
villager | how many times do we have to tell you? the charger puts on a BIGGER pressure than the battery, therefore current flows "backwards" into the battery | 05:36 |
TiagoTiago | I've never heard it was possible for them to have opposite signs in the same length of wire | 05:37 |
TiagoTiago | volt is relative, not absolute | 05:37 |
villager | but the measurement between the battery poles (as opposed to the voltage between battery and charger) will measure how much power is delivered to/from the battery | 05:37 |

villager | let's say you have a 5V battery, and the charger can deliver 10V, and the negative poles of both are both grounded. Then you have three levels: CHARGER+ = 10V, BATTERY+ = 5V, GROUND = 0V... since current always flows from a higher potential to a lower, this forces current towards the + pole of the battery | 05:41 |
villager | disconnect the charger and put in a machine you want to run, and then the current will of course flow from the battery + pole to the battery - pole | 05:42 |

DocScrutinizer | TiagoTiago: PLEASE LISTEN!!! current is in ONE point. Volatge is between TWO points. The both are first instance COMPLETELY unrelated, as in there's no voltage associated to a current | 05:44 |
villager | then the voltage between + and - on the battery is always 5V, but the current can be reversed | 05:44 |
villager | just by attaching the charger... | 05:44 |
*** lmoura has joined #maemo | 05:45 | |
TiagoTiago | If the one point where you measure current is between the two points you use to measure voltage then the sign will always match | 05:46 |
DocScrutinizer | it just happens bq27200 meassures voltage and current of the battery, it as well could measure voltage of the microphone if that would help us more that the current setup. But voltage displayed by bq27200 is NOT responsable or related to the current displayed there | 05:46 |
villager | TiagoTiago: well, you cannot measure current inside the battery, only outside of it... | 05:49 |
*** bugzy has joined #maemo | 05:49 | |
TiagoTiago | if the one point isn't between the two points then you're not measuring the properties of the same thing, you can't use thos two values to calculate wattage, it's like the bodymass index with your dog's weight | 05:49 |
villager | TiagoTiago: there's a physical law that says that unless the circuit has branches, the current is always the same anywhere in the circuit, so you can measure the current anywhere you want | 05:51 |
villager | if the circuit has branches, the total current through each branch must add up to be equal to what it would have been if it was not | 05:52 |
TiagoTiago | What if the branches lead to or from outside the circuit? | 05:53 |
DocScrutinizer | c'mon please stop that nonsense now. It's becoming silly or annoying or dunno what | 05:53 |
villager | if there's a current through those, then it must still add up | 05:54 |
villager | conservation of energy | 05:54 |
DocScrutinizer | villager: don't run into that trap again. Voltage is measured between two points, but given there's no line between those two points (as a voltmeter is of infinite resistance) there's also no location "between" those two points. Current and voltage measurements are unrelated, and connecting them without referring to a particular background aka circuit makes no sense | 05:59 |
villager | DocScrutinizer: yes, but I feel such technicalities would not be helpful to talk about right now... | 05:59 |
DocScrutinizer | nothing has the faintest look like it'S helpful here | 06:00 |
villager | well, perhaps I should be getting back to doing something useful anyway | 06:00 |
TiagoTiago | I do understand that if you ignore a part of the system the signs can diverge, but on a closed system the signs should always agree | 06:02 |
villager | okay, then consider the battery the part of the system under measurement, and the battery is not a closed system, and let's leave it at that... | 06:03 |
pupnik | to generate configure, i run "autoconf" which uses configure.in, correct? | 06:15 |

DocScrutinizer | autotools are a PITA anyway | 06:19 |
njsf | amen DocScrutinizer | 06:23 |
njsf | yet, despite being a PITA, cumbersome, and sometimes wrong, they are still kinda the best in town in terms of comprehensive support for environment detection | 06:24 |
derf | I don't really think that's true. | 06:25 |
derf | You have to put just as much time to get it to work on another platform as always, because if you haven't actually tested it, it won't. | 06:25 |
njsf | derf: I "kinda" agree for projects with few dependencies. With projects with huge dependencies, the network effects of those dependencies also providing ac .m4 files is awesome | 06:34 |

DocScrutinizer | it's ludicrous they report dosages like 1mSv/h for the Fukushima plant a bit off from the reactor buildings, but OTOH the helicopter action had to get stopped yesterday due to radiation levels too high, and today they have equipped the helicopers with Pb shielding for the pilots so they won't get hurt when flying at a level of maybe 100m above the site. This sounds more like 1MSv/h rather than 1mSv/h | 07:45 |
pupnik | off the site upwind is much less than above the burning building | 07:50 |
DocScrutinizer | lofty306: (<lofty306> GE sending 10 gas turbine generators to japan) so is that supposed to help on the FUKU-site? Doesn't Japan have such things themselves? I heard they brought generators to there on day0 or day1, but it didn't work, for unknown reasons. Now they come up with big news they hope to complete a powerline to FUKU today, and start the cooling again. It's really all so three-stooges, freaking scary sh*t | 07:53 |
*** bef0rd has quit IRC | 07:54 | |
DocScrutinizer | pupnik: winds would spread particles that aren't any dangerous *outside* the heli for the pilot inside. Plus a lead shielding wouldn't help at all for that | 07:54 |
pupnik | gamma rays penetrate aluminum etc | 07:57 |
DocScrutinizer | yeah sure, but the mere distance from those microscopic particles... | 07:57 |

pupnik | and they would not be flying at 1,000,000Sv/h | 08:00 |
DocScrutinizer | if the radiation level a 100..200m horizontally off the reactor is at 1mSv then I can't see any serious danger for a heli pilot hoovering a 100m above that | 08:00 |
lofty306 | DocScrutinizer, totaly 3stooges | 08:00 |

DocScrutinizer | better don't say anything and act like 3 stooges, than give full disclosure and reveal how everybody got lied at since 30 years | 10:21 |
nidO | DocScrutinizer: the point actually is more that that report rightly states that the spent fuel pool was low on water, which they tried to refill via helicopter - yet most news outlets have been reporting they were trying to dump water onto reactor cores a-la chernobyl | 10:21 |
*** OkropNick has joined #maemo | 10:21 | |
nidO | when the cores arent even exposed. | 10:21 |
ruskie | sadly most media now-a-days tries to be sensationalistic | 10:21 |
RST38h | Doc: Whoever stands up and gives full disclosure will be automatically assigned to be the guilty party | 10:22 |
RST38h | Hence no disclosure. | 10:22 |
DocScrutinizer | I most recently learnt there might be a SpentFuelPool at block3 as well | 10:23 |
*** dvarnes has quit IRC | 10:23 | |
*** valerius_ has quit IRC | 10:23 | |
RST38h | Each block has a spent fuel pool | 10:23 |
nidO | tbh, the "good news" is that these 40 year-old reactors survived an earthquake several times more powerful than they were designed to without a scratch, and have only fucked up because the backup diesel generators and backup backup generators were washed away | 10:23 |
DocScrutinizer | so they actually got 6 reactor blocks plus 6 SFP and while they were staring at block1,3 reactor, the SFP's at #4, #3, #4, #6 are BBQing their stupid asses | 10:25 |
DocScrutinizer | #4, #3, #5, #6 | 10:26 |

*** Dialekt has joined #maemo | 13:32 | |

neal | How does the N900 do AGPS? The N900 does not support reporting neighboring cellular towers. What is it using instead? | 14:53 |
pupnik | the connected cell tower? | 14:53 |
lardman | SUPL | 14:54 |
*** scoobertron has quit IRC | 14:54 | |
neal | pupnik: You can't do triangulation with one tower... | 14:54 |
pupnik | the tower knows its location | 14:54 |
lardman | nor does it do triangulation afaiu | 14:54 |
*** penguinbait has quit IRC | 14:54 | |
*** mveplus has quit IRC | 14:55 | |
lardman | The AGPS functionality consists of the N900 obtaining ephemeris and alamanac data for its current location as returned by the connected cell tower, afaiu | 14:55 |
lardman | ephemeris being the location dependent one there | 14:55 |
neal | I see | 14:56 |
*** n900evil has quit IRC | 14:56 | |
*** Jade has quit IRC | 14:56 | |
*** MadViking has quit IRC | 14:57 | |
neal | I'm actually a bit confused. | 14:58 |
neal | The agps info is not sent via a TCP/IP connection. | 14:58 |
lardman | how so? | 14:58 |
lardman | yes it is | 14:59 |
*** XenonXZ has joined #maemo | 14:59 | |
neal | Hmm. | 14:59 |
lardman | the N900 talks to a SUPL server somewhere, e.g. the Google one or the Nokia one, and tells it the cellid that it's connected to | 14:59 |
neal | only the cell id? | 14:59 |
lardman | yes, afaiu, I know that SUPL can do other things, but I don't think those are used here | 15:00 |
neal | I thought you just said it downloads the ephemeris and almanac data. | 15:00 |
lardman | yes, but the ephemeris data are location dependant | 15:00 |
lardman | so the SUPL server needs to know what to generate/send to the device | 15:00 |
neal | And that's what it is getting from the supl server? | 15:00 |
*** dneary has quit IRC | 15:00 | |
lardman | yes | 15:00 |
lardman | there are other things that SUPL can do afair, like taking parts of the recorded GPS signal and brute forcing a location from them, but I don't think that's necessary if you have a rough location provided by the cell tower | 15:01 |
lardman | and is also significantly more computationally expensive I'd guess | 15:02 |

neal | I'm building a location-aware network manager | 15:08 |
ruskie | fun | 15:09 |
neal | And I'd like more information than just the currently connected tower. | 15:09 |
neal | Unfortunately, the modem on the N900 appears to either not implement or block queries for neighboring towers. | 15:10 |
neal | I'm trying to figure out other inexpensive (in terms of battery power) sources of location information. | 15:10 |
lardman | cool | 15:11 |
neal | (I don't need the actual geographical location. I just need environmental features to create a fingerprint.) | 15:11 |

lardman | BCMM: direction of sun | 15:14 |
lardman | BCMM: otherwise you'd need to watch the entire day's worth to work out your latitude | 15:15 |
lardman | actually that's wrong isn't it | 15:15 |
BCMM | maybe, but i can see the correct answer in my head now | 15:15 |
BCMM | all you'd get from that would be the elevation of the sun | 15:16 |
BCMM | the angle between "down" and the sun | 15:16 |
BCMM | without knowing which direction teh sun is, that describes a circle of possible locations on the earth | 15:16 |
BCMM | probably, this is based only on visualising it | 15:16 |

merlin1991 | any qt gods here to help me? I'm trying to store an opengl extension method in a function pointer to user it later using http://doc.qt.nokia.com/stable/qglcontext.html#getProcAddress but I can't get the cast right so I can use it (or I define my function pointer wrongly I don't know) | 17:21 |
*** mc_teo`` has quit IRC | 17:22 | |
crashanddie | merlin1991, what language? | 17:23 |
merlin1991 | c++ | 17:23 |
*** crashanddie has quit IRC | 17:23 | |
merlin1991 | hm he left :P | 17:23 |
*** crashanddie has joined #maemo | 17:24 | |
*** crashanddie has joined #maemo | 17:24 | |
crashanddie | merlin1991, can you show your code, and actual errors? | 17:24 |
*** sq-one has joined #maemo | 17:24 | |
merlin1991 | well I tried all sorts of stuff and always get compile time errors, but the main point is, that I'm using this function http://doc.qt.nokia.com/stable/qglcontext.html#getProcAddress wich returns void* and I need to cast that so I can use the return as function pointer | 17:26 |
crashanddie | and we're not going to be able to help you unless you give us some specific examples that will allow us to deduce what kind of cast you need | 17:26 |
*** Tsuyo has quit IRC | 17:27 | |
*** felipec has joined #maemo | 17:27 | |
merlin1991 | I need to cast that to pretty much any type of function pointer since depending on what string I feed it I get back another opengl function (yay for the awesome windows opengl system) | 17:29 |
lcuk | merlin1991, what is the function prototype that the pointer should represent? | 17:29 |
merlin1991 | the very first one I need would be void (GLsizei n, GLuint *renderbuffers) | 17:30 |
crashanddie | for example, you could have glCreateProgram = (PFNGLCREATEPROGRAMPROC)cont->getProcAddress("glCreateProgram"); | 17:30 |
crashanddie | where cont is a QGLContext * | 17:30 |
*** bergie has quit IRC | 17:31 | |
merlin1991 | yeah I found lots of examples like that, but sadly the glext header for windows is missing most of the typedefs like PFNGLCREATEPROGRAMPROC | 17:32 |
crashanddie | get an OS that works then. | 17:32 |
merlin1991 | :D | 17:32 |
merlin1991 | I'd love todo that :P | 17:33 |
merlin1991 | so I need to know I have to put in the ( ) to create for example the pointer to the function with the signature (GLsizei n, GLuint *renderbuffers) | 17:33 |
*** Tsuyo has joined #maemo | 17:34 | |
merlin1991 | (so I can either write the ypedefs myself or copy paste stuff) | 17:34 |
lcuk | merlin1991, yeah | 17:35 |
lcuk | typedef int (*FUNCX)(int a,int b); | 17:36 |
lcuk | FUNCX myfunc = NULL; | 17:36 |
lcuk | myfunc = (FUNCX)getProcAddress("glCreateProgram"); | 17:36 |
lcuk | printf("tada %i",myfunc(1,2)); | 17:36 |

neal | jacekowski: There is a recent patch to ofono to enable getting the neighbor info. | 18:26 |
neal | http://www.mail-archive.com/ofono@ofono.org/msg09177.html | 18:27 |
jacekowski | neal: yeah, but ofono isn't compatible with n900 | 18:27 |
jacekowski | neal: n900 userland | 18:27 |

neal | it's 0x1A | 18:29 |
neal | that message will get you the neighbor cells | 18:29 |
SpeedEvil | neal: That's a patch - as I understand it - to enable ofono to support neighbour cells. | 18:29 |
SpeedEvil | neal: It is _not_ a driver for the low-level modem. | 18:29 |
SpeedEvil | If this was a message of a couple of months ago | 18:30 |

SpeedEvil | Not loading here. | 18:30 |
SpeedEvil | Is it low-level? | 18:30 |
SpeedEvil | I.E. talking directly to the modem? | 18:30 |

dashavoo | ok, as being as everyone seems to be around at the moment, and I'm off home in a minute anyway... I noticed that the power kernel supports mesh networking, does anything actually use it? | 18:53 |
SpeedEvil | The OLPC can. | 18:54 |

BCMM | yeah, it would be pretty cool. .33 has some patches that should improve responsiveness on almost any system under heavy load | 19:03 |
BCMM | unfortunately i am nothing like a kernel hacker | 19:03 |
DocScrutinizer | you might want to ask the SHR dudes on #openmoko-cdevel about what they got so far | 19:03 |
BCMM | DocScrutinizer: i don't really know what the barriers are - the kernel claims to be untainted, so i guess there aren't any binary drivers compiled against a specific version | 19:04 |
DocScrutinizer | aiui they are experimenting with 2.6.36/7 (??) but not for N900 so far | 19:05 |
BCMM | DocScrutinizer: is the only serious issue that there is closed userspace that expects sysfs stuff to be in specific locations? | 19:05 |
DocScrutinizer | yes, I think so | 19:05 |

BCMM | yes, i know that would be a licensing can of worms | 19:06 |
DocScrutinizer | BCMM: a nice idea, I'll ponder about it | 19:06 |
MohammadAG | longer is an understatement | 19:07 |
BCMM | but a binary patch could be applies on teh device | 19:07 |
BCMM | ah | 19:07 |
MohammadAG | I wouldn't worry about bme or mce | 19:07 |
BCMM | MohammadAG: the new sysfs paths are much longer? | 19:07 |
MohammadAG | and more confusing, at least to me | 19:07 |
MohammadAG | I felt lost in sysfs, unlike on 2.6.28 | 19:08 |
BCMM | i guess that would pretty much prohibit modifying string literals in the binaries? | 19:08 |
BCMM | MohammadAG: so which important stuff moved? | 19:08 |
MohammadAG | depends, which binaries? | 19:08 |
MohammadAG | all paths changed, in one way or another | 19:08 |
ZogG | MohammadAG 2.6.28 is so ooold | 19:08 |
ZogG | it's os yesterday | 19:08 |
MohammadAG | ZogG, less confusing though | 19:08 |
*** lofty306 has quit IRC | 19:08 | |
BCMM | MohammadAG: dunno; whichever the ones with hardcoded sysfs stuff are | 19:08 |
MohammadAG | 2.6.38 is shit, at least on my laptop | 19:08 |
ZogG | MohammadAG what aer you trying to do? | 19:09 |
BCMM | MohammadAG: in which respects? | 19:09 |
MohammadAG | nothing | 19:09 |
ZogG | MohammadAG i have 38 now | 19:09 |
MohammadAG | it can't resume from standby | 19:09 |
ZogG | and 37 on laptop | 19:09 |
MohammadAG | or from hibernate | 19:09 |
BCMM | MohammadAG: "I wouldn't worry about bme or mce" in what way? | 19:09 |
ZogG | MohammadAG, you have it on laptop | 19:09 |
MohammadAG | BCMM, they were updated for MeeGo | 19:09 |
ZogG | and didn't bother to set it up =) | 19:09 |
MohammadAG | yes, I have it on my laptop | 19:09 |
MohammadAG | I went back to .35, a bit more stable | 19:10 |
BCMM | MohammadAG: using tuxonice/suspend2 patches? | 19:10 |
MohammadAG | oh and only one core is visible on .38 | 19:10 |
ZogG | MohammadAG, are you using stable or unstable? | 19:10 |
MohammadAG | it's an i5 ffs... | 19:10 |
MohammadAG | ZogG, natty kernel | 19:10 |
*** jpe has joined #maemo | 19:10 | |

MohammadAG | 2 i5s | 19:11 |
MohammadAG | a desktop and a laptop | 19:11 |
ZogG | damn you | 19:11 |
MohammadAG | bought the laptop from jordan, 2000NIS | 19:11 |

MohammadAG | I'm not going to jordan anytime soon :P | 19:12 |
* RST38h is getting a distinct feeling that .IL sucks badly | 19:12 | |
MohammadAG | heh | 19:13 |
BCMM | MohammadAG: just saying, AFAIK tuxonice is still at .38, so your hibernation will indeed suck | 19:13 |
ZogG | MohammadAG, talk to me when you do | 19:13 |
BCMM | i mean, still at .37 | 19:13 |
BCMM | so either you're using vanilla suspend, which sucks, or you're using an experimental tuxonice patch | 19:13 |
ZogG | BCMM, do you use gentoo-sources? | 19:14 |
BCMM | ZogG: sys-kernel/tuxonice-sources | 19:14 |
ZogG | BCMM, just for hibirnate? | 19:14 |
BCMM | ZogG: which has the gentoo-sources +tuxonice | 19:14 |
ZogG | BCMM, seriosly? | 19:14 |
BCMM | ZogG: hibernation is the only difference between that and gentoo-sources | 19:14 |
ZogG | i may switch | 19:14 |
ZogG | on laptop | 19:15 |
BCMM | ZogG: which bit provokes incredulity? | 19:15 |
BCMM | ZogG: the only downside is that it lags slightly behind vanilla | 19:15 |
*** zap has joined #maemo | 19:15 | |
BCMM | any right now, it lags behind gentoo- a little too | 19:15 |
BCMM | ZogG: gentoo and vanilla are both at .38, tuxonice is at .37 cause of upstream | 19:15 |
BCMM | ZogG: eix sys-kernel/tuxonice-sources, it's right there in the description | 19:16 |

ZogG | BCMM, why don't they include it in vanilla? | 19:17 |
BCMM | ZogG: politics... | 19:17 |
BCMM | ZogG: iirc, they want to be in the kernel.org kernel | 19:17 |
BCMM | ZogG: but somebody doesn't agree with how their doing thigns | 19:17 |
BCMM | wants to move more stuff to userspace, i think | 19:17 |
BCMM | ^they're doing things | 19:17 |
BCMM | i don't think there's any disagreement that it beats the existing suspend support; it's just that somebody is working on a supposedly superiour replacement | 19:18 |
*** MadViking has quit IRC | 19:19 | |
BCMM | ZogG: the alternative, more user-space-ish, suspend implementation is uswsusp | 19:20 |
ZogG | but it's the only thing that works | 19:20 |
MohammadAG | I wish the N900 had suspend to RAM | 19:20 |
MohammadAG | I don't mind DocScrutinizer's battery swap method, but it needs a wall charger, and a wall | 19:21 |
ZogG | does it? | 19:21 |
BCMM | ZogG: what is? tuxonice? | 19:21 |
ZogG | yes | 19:21 |
pupnik | a better way to suspend/resume apps would be great | 19:22 |
BCMM | ZogG: yeah, it works much better than anything else right now | 19:22 |
ZogG | MohammadAG, what about air charger and air | 19:22 |
macmaN | hum | 19:22 |
ZogG | BCMM, i hate politics | 19:22 |
MohammadAG | ZogG, not much air in the atmosphere | 19:22 |
BCMM | ZogG: imho, the objections to it are too philosophical | 19:22 |
ZogG | people are tarded | 19:22 |
BCMM | pragmatically, it wins | 19:22 |
DocScrutinizer | MohammadAG: N900 has s2ram, SpeedEvil tested it, and I don't see how that helps. And my hotswap works with external battery packs as well | 19:22 |
BCMM | dunno why this is a problem, because from where i'm standing, that's what Linux itself is | 19:22 |
*** jrocha has joined #maemo | 19:22 | |
ZogG | who is against it should do better than | 19:22 |
BCMM | a decent balence between doing it right and actually doing it | 19:23 |
BCMM | (compare with Hurd) | 19:23 |
MohammadAG | DocScrutinizer, suspend, swap battery, resume | 19:23 |
MohammadAG | basically, I don't want to reload whatever i had opened | 19:24 |
DocScrutinizer | won't work, RAM as well needs power | 19:24 |
ZogG | BCMM, i heard that if you want to maintaince somethign to kernel you need to use k&r book syntaxes (the book you told me about) | 19:24 |
MohammadAG | it works fine with my laptop | 19:24 |
ZogG | MohammadAG, why do we need suspend on n900? | 19:24 |
BCMM | ZogG: yeah, i think that was one of the things Reiser fought with the kernel team over | 19:24 |
MohammadAG | hmm, wtf am I saying | 19:24 |

MohammadAG | how does that work? | 19:25 |
DocScrutinizer | ask SpeedEvil | 19:25 |
MohammadAG | deb command? | 19:26 |
BCMM | ZogG: i think i was incorrect, formatting standards wasn't the complaint about reiserfs4 | 19:26 |
MohammadAG | there's no deb command | 19:26 |
ZogG | BCMM, i think maintaince was | 19:26 |
BCMM | ZogG: it seems a bit petty, but it's actually kinda reasonable to have a project like that use similar conventions througout | 19:26 |
DocScrutinizer | echo foo >/sys/bar | 19:26 |

*** dominikb has quit IRC | 19:31 | |
ZogG | i don't get that too | 19:31 |
ZogG | it's only kernel | 19:31 |
BCMM | ZogG: yeah, XFree86 was developed in a not-very-public way, open but basically controlled by a small group of people | 19:31 |
MohammadAG | the kernel isn't a big problem | 19:31 |
MohammadAG | maemo is | 19:31 |
ZogG | and there should be no software releated things | 19:31 |
ZogG | so hardware si the same | 19:32 |
MohammadAG | telephony functions will most likely break | 19:32 |
MohammadAG | that retarded battery applet might break too | 19:32 |
ZogG | BCMM, i like the revolution of ffmpeg team | 19:32 |
BCMM | ZogG: the decision to change the license was the best thing to happen to X11 in ages, since the resulting fork ended up being developed much more actively | 19:32 |
ZogG | MohammadAG, are those thing built in? | 19:32 |
BCMM | MohammadAG: why would they break? | 19:32 |
MohammadAG | define built in | 19:32 |
MohammadAG | cause they listen to hal, which is deprecated | 19:33 |
BCMM | MohammadAG: do you mean that the telephony driver wouldn't work on a modern kernel? | 19:33 |
BCMM | ah, hal... | 19:33 |
BCMM | MohammadAG: it's deprecated, not gone | 19:33 |
ZogG | BCMM, i like forks and branching but i like good stuff being merged to master branch | 19:33 |
MohammadAG | telephony app will break | 19:33 |
MohammadAG | MeeGo uses ofono | 19:33 |
ZogG | and not that you have 5 branches and everyoe has things you want and you can't combine | 19:33 |
BCMM | MohammadAG: i use hal on a 2.6.37 kernel on my desktop | 19:33 |
BCMM | (because i'm on an old version of KDE) | 19:33 |
ZogG | MohammadAG, and maemo? | 19:33 |
BCMM | MohammadAG: it will break why? | 19:34 |
ZogG | BCMM, hal? | 19:34 |
MohammadAG | BCMM, I'm not sure if bme has hal on MeeGo | 19:34 |
ZogG | are you fucking srs? | 19:34 |
MohammadAG | uses hal* | 19:34 |
ZogG | hal had a good run | 19:34 |
ZogG | at the end as it was working god with X finally it got deleted =) | 19:35 |
ZogG | damn | 19:35 |
MohammadAG | I need to figure out gstreamer... | 19:35 |
BCMM | ZogG: iirc, kde 4.6 is the first KDE release that doesn't use HAL | 19:35 |
BCMM | i'm still on 4.5 | 19:35 |
ZogG | BCMM, you have flags =) | 19:35 |
ZogG | USE=-hal =) | 19:35 |
MohammadAG | basically, how to use gstreamer widgets in Qt | 19:36 |
BCMM | it isn't compulsory, but it is required for GUI mounting/unmounting of removable media | 19:36 |
ZogG | though i waited a lot for xfce4 to use udev insted of hal | 19:36 |
ZogG | it wa or hal or mount manually =) | 19:36 |
BCMM | like i said, they modifed Solid in 4.6 to not use HAL | 19:36 |
ZogG | almost everyone did | 19:36 |
ZogG | they use udev | 19:36 |
BCMM | anyway, deprecated doesn't mean it doesn't work any more, so i still don't understand why telephony should break | 19:37 |
ZogG | but latest X and hal were fine with autodetection my xorg.conf was empty, everything out of box | 19:37 |
BCMM | "HAL is in maintenance mode - no new features are added." - it's not even unmaintained | 19:37 |
APTX | as a neat side effectof dropping hal, the ability of setting a keyboard layout vanished yet again | 19:37 |
ZogG | BCMM, as i understood maemo uses something that is not in meego kernel or changed with something and unleast you have source of dialing and other apps that are built in you can't fix them and you can't replace the | 19:38 |
ZogG | APTX, not true | 19:38 |
ZogG | APTX, i don't have hal and i manage good with keyboard setting even with no DE | 19:39 |

Venemo | DocScrutinizer51, on the N900, what's the performance difference between fixed and floating point calculations? | 20:14 |
jacekowski | Venemo: huge | 20:14 |
jacekowski | Venemo: floating point on maemo is all emulated | 20:14 |
Venemo | jacekowski, I know, but how much is "huge" in numbers? | 20:15 |
DocScrutinizer51 | magnitudes | 20:15 |
Venemo | huh! | 20:16 |
Venemo | so if I use fixed-point calculations, then my stuff will run more than 10× faster? | 20:16 |
jacekowski | assuming that calculations are your main thing | 20:16 |
jacekowski | but then even more than 10x | 20:16 |
jacekowski | i would say more like 100x | 20:17 |
DocScrutinizer51 | if it's all just divisions and muls then yes | 20:17 |
Venemo | well, Qt Graphics View uses lots of fp calculations | 20:17 |
SpeedEvil | If you can use NEON, things may change. | 20:17 |
SpeedEvil | Also - 100 may be pessimistic | 20:17 |
SpeedEvil | 10 is probably optimistic though | 20:17 |

jacekowski | Venemo: i don't remember | 20:23 |
jacekowski | Venemo: it was just one post on one of kernel related mailing lists | 20:24 |
jacekowski | Venemo: and you can't use floats in kernel for performance reasons | 20:24 |
*** joejoe has quit IRC | 20:24 | |
jacekowski | Venemo: context switches out of kernel/to kernel would take much longer | 20:24 |
jacekowski | Venemo: if it would have to save fpu stack | 20:24 |

DocScrutinizer51 | you really don't need nor want floats for audio processing generally | 20:25 |
Venemo | jacekowski, I read your link. it talks about softfp vs. hardfp (and 40% difference which is real nice), but it doesn't talk about fixed points :) | 20:26 |
jacekowski | Venemo: well, on maemo you only have softfp ( or just soft, i'm not sure ) | 20:26 |
Venemo | jacekowski, sure | 20:26 |
jacekowski | Venemo: and fixed points are done natively therefore would achieve performance of hardfp at least | 20:27 |
Venemo | jacekowski, this is why I want to know how much I would gain by using fixed-point calculation | 20:27 |
Venemo | jacekowski, fixed-points are calculated as integers as far as the CPU is concerned | 20:27 |
jacekowski | yes | 20:27 |
jacekowski | that's why i'm saying fixed points are done natively | 20:27 |
Venemo | yes | 20:27 |
jacekowski | therefore no need to emulate anything | 20:28 |
Venemo | and it's usually reasonable to say that integer arithmetics is usually a lot faster than floating point. | 20:28 |
jacekowski | like with softfloats | 20:28 |
*** renato has joined #maemo | 20:28 | |
*** pcacjr has joined #maemo | 20:28 | |

Lantizia | Lo... On wikipedia I just read this... £Even though MeeGo was initiated as collaboration between Nokia and Intel, the collaboration was formed when Nokia was already developing the next incarnation of its Maemo Linux distribution. As a result, the Maemo 6 base operating system will be kept intact while the Handset UX will be shared, with the name changed to “MeeGo/Harmattan”." | 20:50 |
Lantizia | Does this essentially mean the N9 will run MeeGo/Harmattan and that it will continue to be Debian-orientated Maemo at heart but with a MeeGo UX on top? | 20:50 |
*** Talus_Laptop has quit IRC | 20:51 | |
DocScrutinizer | actually not because of watchdog but because of dsme | 20:51 |
MohammadAG | that's always been the case for Maemo 6 | 20:51 |
MohammadAG | watchdog = dsme | 20:51 |
MohammadAG | lifeguard as it's called | 20:51 |
MohammadAG | killing X in R&D mode = dropped into a black screen (framebuffer console not in default kernel) | 20:52 |
*** sq-one has joined #maemo | 20:52 | |
Lantizia | MohammadAG, so surely this means the new MeeGo UX will be debian-packaged? | 20:52 |
MohammadAG | MeeGo is RPM based | 20:53 |
MohammadAG | Maemo 6 is debian based | 20:53 |
MohammadAG | different OSs | 20:53 |
MohammadAG | different openness | 20:53 |
Lantizia | "As a result, the Maemo 6 base operating system will be kept intact while the Handset UX will be shared, with the name changed to “MeeGo/Harmattan”." | 20:53 |
Lantizia | By "base operating system" I'm thinking Maemo 6 will continue to be debian and dpkg | 20:53 |
Lantizia | if it's dpkg based... and the MeeGo UX is going on top... then it'll have to be in debian dpkg format no? | 20:54 |
MohammadAG | yes, but MeeGo UX != MeeGo | 20:54 |
Lantizia | I'm not saying it is | 20:54 |
MohammadAG | and Maemo 6 != MeeGo | 20:54 |
Lantizia | I'm not saying that either | 20:54 |
MohammadAG | Maemo was and always will be debian based | 20:54 |
Lantizia | I've been quite explicit about how I've phrased things | 20:54 |
MohammadAG | Maemo 6 is just using MeeGo's UX | 20:55 |
MohammadAG | but it's still maemo, and probably a bit more closed | 20:55 |
Lantizia | Right so the N9 will run MeeGo/Harmatted (AKA Maemo 6) and will be Debian based and runs the MeeGo UX which will be install/upgraded via dpkg right? | 20:55 |
jacekowski | there will be no N9 | 20:55 |
MohammadAG | yes, and that ^ too | 20:55 |
Lantizia | jacekowski, well Nokia have been claiming a MeeGo handset is still due - so the N9 surely? | 20:56 |
jacekowski | no | 20:56 |
MohammadAG | N950 | 20:56 |
jacekowski | N950 | 20:56 |
ShadowJK | Not convinced anyone would use MeeGo UX.. | 20:56 |
MohammadAG | ShadowJK, long live cordia | 20:56 |
Lantizia | ok so the N950 will run MeeGo/Harmatton... (formerly known as Maemo6)... a _Debian_ based OS that will run the MeeGo UX which will install/upgrade via apt/dpkg ? | 20:57 |
ShadowJK | I mean, MeeGo *UX are like placeholders saying <dear bigcorp, insert random ui here> | 20:57 |
Lantizia | is _that_ statement true? :D | 20:57 |
MohammadAG | yes | 20:58 |
Lantizia | Cool :) | 20:58 |
MohammadAG | ShadowJK, true | 20:58 |
Lantizia | So if... _if_ there is ever a Maemo 7 (properly known as... MeeGo/FuckKnows)... is it likely to leave Debian behind? | 20:58 |
Lantizia | since Novell have an openSUSE version of MeeGo.... can't Nokia just have a Debian version of MeeGo (formerly known as Maemo lol) | 20:59 |
*** vblazquez has quit IRC | 20:59 | |
MohammadAG | nah, maemo will be maemo | 20:59 |
Lantizia | but there is no more Maemo... there is only MeeGo/Whatever now | 20:59 |
chx | there is a Maemo maintained by the community as best as they can | 21:00 |
chx | this is my understanding. | 21:00 |
ShadowJK | opensuse can't claim opensuse+meego is meego, and i dont think they can use the meego name | 21:00 |
ShadowJK | so i dont see how nokia can call it meego either | 21:00 |
Lantizia | no but they _can_ use the MeeGo UX | 21:00 |

Lantizia | I'd rather see a range of MeeGo UX based distributions that are based/backed by your garden variety desktop distro makers (like openSUSE, Debian, Ubuntu, Fedora etc...). Maemo happened to be Debian based, so Nokia can continue to make they're own variety of a MeeGo UX based distro using Debian at it's core right? | 21:02 |
Lantizia | *their | 21:02 |
Lantizia | i.e. Maemo continues... name slightly changed (again)... and Hildon is traded for MeeGo UX... the end. | 21:03 |
Lantizia | MohammadAG, wishful thinking or am I on the nose here? | 21:04 |

Lantizia | just as MeeGo/Harmatten sounds like it's going to be Maemo running the MeeGo UX | 21:05 |
Lantizia | i.e. still debian | 21:05 |
Lantizia | yacc, yeah that hurts me inside :( | 21:06 |
yacc | Lantizia, hence Nokia's announcements about their roadmap in the past were kind of vaporware-ish, but with the new course from the CEO downward, who can fathom what Nokia will deliver in n months? | 21:06 |
Lantizia | yacc, I like to look at it as ... they got tired of critics moaning about Symbian, didn't think MeeGo was polished enough to replace Symbian yet... wanted $1 billion dollars... thought fine we'll have WP7 to replace Symbian only and if it goes tits up they can blame Microsoft and maybe Meego (still going on the Nxxx range) can be brought back in to the limelight | 21:07 |

yacc | Lantizia, if they had decided to abandon their developer base, they probably should have taken Android, and added Nokia services (they are one of the few companies that own digital maps for most of the globe) instead of loosing completely the control of the software stack. Or leave the Google services in and take the bribe that Google offered, ... | 21:08 |
yacc | Lantizia, Well, if there wouldn't be the small detail that Mr Elop happens to be raised in the MS-way, .... | 21:09 |
Lantizia | Nah... don't agree, I still like the idea that the Linux Foundation are setting the rules on what the minimum base OS should have... and the idea of all using the same mobile-orientated UX | 21:09 |
*** vanadismobile has quit IRC | 21:09 | |

yacc | pupnik, I don't think so, because WP7 equals a very strict list of hardware requirements (which are said to be slightly dated, kind of 1-2 years compared to current Android/iPhone handsets), so if they don't get a special dispension from MS, they'll be able to produce more or less the same phones that are currently on the market, now with Nokia logo, and slightly more flash, and slightly more mega pixel then the others, and we offer it in a dozen colors, ... | 21:23 |
pupnik | yacc: i think the 'esc button' requirement should have been part of the N900 | 21:23 |
