00:34.50houkimeofftopic - omg, have just read about Kerbal Space Program controversy with new owners TakeTwo spying on users via game and having a bs eula... And there're people who say we don't really need opensource gaming... Turns out we need.

00:54.22houkimeTakeTwo even went as far as to claim their ownership on the modder content in what looks like an attempt to prevent a new foss spacegame hatching from open modded assets and scripts.
01:19.41OksanaThat's like... Don't publish your photographs/anything on Internet unless you have read EULA/Terms&Conditions, and have seen that you are the owner of your content.
01:19.51OksanaIn short, common sense.

01:24.06houkimeI believe some of modded stuff is even on github under gpl3 or similar but still this corp is claiming sth. I guess what's on github is relatively safe as TakeTwo should not win a lawsuit under any sane jurisdiction.
01:24.40houkimeLike it is if I proclaim myself an owner of Linux.
01:25.20houkime*an exclusive rights owner.
01:25.52houkimeand try to make any copy illegal without my blessing
01:27.38houkimethe thing is they proclaim their ownership AFTER the mods are made.
01:28.26houkimebecause they weren't a game owners when modders were starting up. They are the new ones.
01:33.15houkimeso technically KSP community still can start their own game with modded assets that were properly licensed and that they already have. Not sure they would do that though.
01:34.40houkimeIt was a thing with Portal2 though when modmakers branched off and made their own gamestudio (partly reusing modded assets) so it is not impossible.
01:38.00Oksanais not interested in computer games - waste of time, and increase obesity due to the encouraged sedentary life-style. But that's my personal opinion, and I tend to be very opinionated at times.
01:40.40houkimeI personally think that games and fiction is just another form of planning and presenting/simulating concepts.
01:41.36OksanaPossibly. I am well familiar with concept of spending lots of time on fiction - reading is one of my favourite pastimes.
01:42.50Oksanalooks at http://neo900.org/stuff/block-diagrams/neo900/neo900.html and wonders where FM TX/RX is connected to 3.5mm - FM receiver uses 3.5mm headset as antenna, doesn't it?
01:44.42OksanaAh, here. FM_ANT
01:45.10houkimeemm... Why should it use a headset as antenna? There is just an antenna for that.
01:45.32houkimeit has a place on the pcb and I actually showed it in my video
01:45.38OksanaFM transmitter has internal antenna. FM receiver always uses headphone as antenna for reception.
01:46.35OksanaTransmitting FM for a short distance is doable with tiny internal antenna. Receiving FM from a far away station is better done with long whip-like antenna - aka, headphone.
01:47.09houkimehmmm. This makes sense
01:47.27OksanaTransmitting FM via an external antenna would have broken the regulations, probably, due to jamming the radio waves. Hence, transmitting via internal antenna only.
01:48.25OksanaQuestion: Can Neo900 play radio when OS/CPU is shut down? Because http://www.ti.com/product/tlv320aic34 has the functionality for it.
01:49.04DocScrutinizer05yes, makes sense and Oksana has it 10% correct
01:49.08DocScrutinizer05100 even
01:49.30OksanaOne of obvious use-cases would be to have radio-alarm (and yes, alarm can already ring when OS/CPU is shut down; but it rings currently from an audio file)
01:50.00DocScrutinizer05Oksana: I tried to implement it this way (play radio without CPU support) but I forgot if I achieved it
01:50.08Oksanapoints to https://wiki.maemo.org/N900_Hardware_Audio_Codec
01:50.10DocScrutinizer05prolly I did

01:50.52DocScrutinizer05wait wait. what? Radio Alarm?
01:51.50OksanaYes. Like, ordinary clock+alarm devices have radio-alarm functionality built-in, most of the time. But they all need 240V power supply.
01:52.10DocScrutinizer05iirc we have the FM radio in/out simply in parallel to line-in/out
01:52.54DocScrutinizer05so if that's true, you could even hook your home stereo to 3.5mm line-out and play FM radio with CPU powered down ;-D
01:52.58OksanaSince alarm can wake up N900/Neo900 even when OS/CPU is shut down, and radio can be played even when OS/CPU is shut down, it means that it is possible for wake-up alarm to play radio instead of audio file.
01:53.54DocScrutinizer05which alarm could "wake up N900/Neo900 even when OS/CPU is shut down" (and stays shut down, and how)?
01:54.37OksanaNot sure about "stays shut down", because alarm usually asks user "Switch on the device? Yes/No"
01:54.39DocScrutinizer05any RTC alarm would simply power up or nonmaskable-IRQ the CPU
01:55.21DocScrutinizer05and yes, CPU then notices it been woke up by RTC alarm and pops up such a requester if needed
01:56.05OksanaHmm, so CPU has already woken up due to alarm, partially. Just hasn't loaded the whole OS/desktop, yet?
01:56.10DocScrutinizer05actually the question is misleading, should be "keep the device powered up, or go to power-down state again?"
01:56.16DocScrutinizer05yep
01:57.04DocScrutinizer05sorry, afk again
01:57.17DocScrutinizer05I'm busted
01:57.42DocScrutinizer05wasted?
01:57.52DocScrutinizer05zombie
01:58.05OksanaRest well :-)
01:59.10houkimewpwrak says that he doesn't have enough time so I'm currently trying to make eeshow to work with both kicad5 and kicad4
01:59.21DocScrutinizer05re FM ant: I changed that a bit, so both FM RX and TX whould work via internal and headset whip antenna, though to a massively different degree of functionality
02:00.39OksanaHuh, fascinating...
02:01.43DocScrutinizer05plus internal had 3rd function for WWAN MIMO
02:01.54DocScrutinizer05in 3G
02:02.07DocScrutinizer054G?
02:03.08OksanaCurrently reading http://wiki.maemo.org/N900_Hardware_Chipset , I guess USB PHY is used in Neo900 (unlike N900), because TWL5030B is connected to USB#0 (and modem to USB#1 and hackerbus to USB#2)?
02:04.37Oksana>> MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi), IEEE 802.11ac (Wi-Fi), HSPA+ (3G), WiMAX (4G), and Long Term Evolution (LTE 4G). <<
02:05.47DocScrutinizer05houkime: great
02:07.29houkimethe changes are in sch files and .pro and they are related to symbol lookup in libraries.
02:08.01houkimeso basically there needs to be 2 lookup modes now separate for kicad4 an kicad5
02:28.14*** join/#neo900 xmn (~xman@user-0cdft2n.cable.mindspring.com)
02:57.06DocScrutinizer05yes, AND the tricky story starts with version control system aka git, and the correlating between lib component version and project file schematics version
02:58.18DocScrutinizer05IOW when you open a schematics from Dec 2017, you want the symbols from Dec 2017 which originally been used when the schematics got drawn
03:00.06DocScrutinizer05kicad has a few concepts in this regard that are invented by a troll with a gas brain.
