And i was wrong dhcpcd is the default client archlinux uses which explains why /sbin/dhclient was missing.
(read this from documentation, with my eyeballs from Journeyman's link)
 
ifconfig is still my lart of choice
 
can you send over that python ipv6 dns server app to me, pretty please
 
@qasdfdsaq I THINK some distros dropped it completely
@bob protip. Anyone who documents linux with a video is shit at documentation.
 
@JourneymanGeek you can compile it from here gnu.org/software/inetutils @ifconfig
 
12:08 AM
@Dave I consider custom compiling applications to be a terrible idea unless absolutely necessary
 
not i.. i dont always like every library dependency for other functionality compiled into my executable that's not needed for applications that are installed.. so i like to compile from source..
 
@Dave Its my opinion but its bad from a maintainance standpoint
 
True true.. But if you were into compiling from source, you'd probably use gentoo instead if you wanted that customization. im total Linux from Scratch -- at least most people that do would rather use gentoo
Other benefit is cpu optimizations
thats about it.
 
and maintain everything? ;p
 
like -funroll-loops etc
Agreed thats annoying.
 
@JourneymanGeek None that I've come across yet...
 
@SolidSnake: I actually do not know that answer.
 
@JourneymanGeek @qasdfdsaq Today I was asking about making CentOs reading the Raid array.
I dropped to the terminal and `modprobe raid1`. No errors. `modprobe md` instead gives `module md not found` and CenOs still seeing the partitioned array as one GPT partition table.

Any other hints?
 
That sounds like a missing kernel module
 
@Dave Yes. I don't get which one! :/
 
bob
12:19 AM
GUYS!!!
dave and journey! I got it!
his video is deprecated
 
lsmod will give you a clue of which filesystem modules are loaded /proc/filesystems will tell you which filesystems your kernel supports
based off that that, that should hint which ones you may be missing.
 
bob
thanks for the link btw... I havn't see that before
do you want to know (for your knowledge) what was the answer?
 
@SolidSnake try ... mdraid
@bob if you're going to use arch, get familiar with their docs
I use them a lot and I don't even use arch
 
oh module md not found.. god im blind
 
bob
haha yea I fould it was too difficult to follow them and rather watch a video but its not up to date so
 
Bob
12:23 AM
@allquixotic are you around?
 
@JourneymanGeek modprobe mdraid not working
 
Bob
Or, actually, anyone else with an Android phone, willing to install Firefox, and with a wired headset.
Oh, and a Bugzilla/Mozilla account.
 
(also, just to remind folk, we typically don't do live support here)
 
@JourneymanGeek: He doesnt have md module compiled with his kernel.
 
12:23 AM
@Dave hm
 
not sure where it's @ in make menuconfig though
 
Did I mention i hate custom compiling things?
Yes. I. Did ;p
 
modprobe md instead gives module md not found

Bob
So, yea. If there's anyone who matches those above - mind helping me test/confirm a bug?
 
12:24 AM
Oops wrong window
 
Bob
Or even without the Mozilla account.
 
@Bob, i would but im not @ home.. about to head home though.
@SolidSnake : that modprobe md could be a false positive as well if it wasnt compiled as a module but directly in the kernel.
 
@Dave How can that be possible if CentOs can create RAID within the installation process.
 
what i just said^
anyhow, heading home. wife is making me a sandwich and she wants me to eat it.
 
Sorry. Pushed send just in the same time you posted. The thing is that I cannot see `/dev/md0` in devices (while the single physical HDDs) are visible.
If booting with GParted live gparted sees the RAIDS.
@JourneymanGeek Sorry man. Better place to look for? IRC #centos?
 
12:31 AM
Typically I'd suggest the main site
 
@JourneymanGeek Ok. I will try to look on the forums. Thanks in any case.
 
(for one thing, people who do that, do that a lot, and it slightly annoyed the regulars. On the other hand, we have situations like this where 2-3 people do it. If its not ok on the main site, it could be ok here. Otherwise...)
 
@SolidSnake It's modprobe raid1
 
I'm sure I linked him the docs 12 hours ago
Though I linked ones for CentOS 5
 
12:38 AM
@JourneymanGeek @qasdfdsaq Yep. The process of creating the arrays were carried on with Gparted live cd and not CentOs livecd following http://www.linuxplanet.com/linuxplanet/tutorials/6514/1/ and https://wiki.archlinux.org/index.php/Software_RAID_and_LVM#Prepare_the_hard_drives

I have two RAID arrays, md0 and md1. md1 is raid10 with LVM on top. The volumes I created on top of it `lvcreate` are seen by CentOS
 
so your raid drivers are probably there?
(I donno, I don't use raid. I think its a silly idea for my use case)
 
I guess lsmod and dmesg | grep -i raid would tell you something
 
which is the boot drive?
 
Wait, how is it seeing volumes on the RAID when it can't see the RAID
 
@JourneymanGeek I don't know if the abstraction layer of LVM takes care of that. The problem is (and that applies even to the guide you linked -- `mount /dev/md_`) I do not have mdX devices in /dev.

The only thing the bothers me is that in the how to they specifically talk about **partitionable** RAID. I did not created partitionable RAID (if it's just to name them like mdX_dX. It's enough to make them partitionable)
 
12:45 AM
naw
 
Any RAID is partitionable
 
/boot typically cannot be in a soft raid or LVM iirc
 
It can be used in SoftRAID fine
 
@Bob am now
 
(I think I better butt out. I clearly don't know shit about raid ;p
 
12:47 AM
@Dave I did no such thing
 
@JourneymanGeek It's "unsupported" on many distros, and it's only RAID-1 (and sometimes RAID-Z) that's supported.
 
Bob
@allquixotic Any chance you could help me test the Fx on Android thing?
 
Same for all OSs really, and the reason is fairly simple - /boot is read-only during boot.
 
Bob
The recommended setup for root-on-ZFS involves creating a mirror mdraid volume for /boot
(of course I just went a completely different path with UEFI and ignored GRUB entirely)
 
The only OS I've used that supports booting from anything other than software-RAID-1 out of the box is probably Solaris
All my servers are booting from soft-RAID-1 though
 
12:51 AM
@Bob I don't have easy access to an android device
 
Bob needs access to an Android device?
 
I could test it on Bluestacks but that's about it
 
Bob
Ah :\
Needs to have headset controls so an emulator is probably out :\
 
I have a few
 
hmm
 
12:52 AM
And I have many headset controls too
 
I'll dig around
 
Bob
28 mins ago, by Bob
Or, actually, anyone else with an Android phone, willing to install Firefox, and with a wired headset.
Well, if @qasdfdsaq is willing to help :)
 
Oh I already have Firefox installed
 
`lsmod` is correctly displaying raid1 module. `dmesg | grep -i raid` shows something like: raid0 personality registered for level 0 [...] until raid 6. Then I have md/raid10:md126 active with 4 out 4 devices
md/raid1;md127 active with 4 out of 4 mirrors.

Thos last two lines seems to resemble my arrays...
 
Bob
Just wanted to quickly test a bug.
 
12:53 AM
(Why I'm not formatting right the inline code o.O)
 
@SolidSnake So they're there, just not in /dev/
@Bob Go on
I would have offered earlier, but I haven't really been paying attention since attractive woman relaxing. outdoor shot in sand - Stock image appeared on my screen
 
bob
hey what linux environment are you guys using?
desktop env*
 
@qasdfdsaq Sorry man how can I find them?
 
bob
KDE?
 
@SolidSnake I dunno, depends what you're looking for and why?
 
Bob
12:57 AM
@qasdfdsaq Ok, so. The problem is Firefox swallows media play/pause button presses.
I've already tested. I just wanted confirmation and preferably someone else commenting on the bug report.
This seems to occur both via Bluetooth and with a wired headset. I'm focusing on the wired headset case.
But having tests for BT would be great too if it's not too much trouble.
 
I should probably update FF too
 
Bob
So: start playing music. via Spotify, whatever.
Play/pause should work.
 
Yeah I have BT controls on my BT headset and also BT LE controls on my "smart"watch
 
Bob
Open Firefox. Just sit on some webpage.
Play/pause stops working.
Go to any other app, homescreen, etc. Play/pause works again.
Volume always works, even inside FF.
That's my observed behaviour. Would appreciate it if you could test that.
 
Well my browser history in Firefox looks dodgy
 
Bob
1:00 AM
lol
 
`dmesg | grep -i raid` shows something like: raid0 personality registered for level 0 [...] until raid 6. Then I have md/raid10:md126 active with 4 out 4 devices
    md/raid1;md127 active with 4 out of 4 mirrors.
 
Bob
 
@SolidSnake needs to be a line on its own
 
Bob
If you happen to have a BMO account, you could post the confirmation there. If not, let me know and I'll just say I got someone else to test and confirm...
 
I don't know what a BMO account is
 
Bob
1:02 AM
@qasdfdsaq sorry, bugzilla.mozilla.org :P
 
@qasdfdsaq 2 lines up and to the right....
 
@qasdfdsaq The thing is that the raid1 (md0 on Gparted LiveCD and md127 apparently here on CentOs) should be partitioned in three partitions that on GpartedCD are seen correctly (md0p1 ...). Here CentOs in the GUI jus shows a single GPT Partition Table (imgur.com/eQ4FEoZ)
 
And that would be a no
OK so confirmed it does exactly as you describe with wired headset. Anytime firefox window is active, play/pause on the headset doesn't work
Any time it's backgrounded, hidden, behind lockscreen, etc. it works fine. Volume keys always works
 
Bob
@qasdfdsaq Great. Thanks.
 
My BT-LE controls on my smartwatch still work while in Firefox though, but I believe there's some weird intermediary listener in play there
 
Bob
1:03 AM
Mind if I link here in the bug report?
 
Sure >_>
 
Bob
@qasdfdsaq Yea, my Pebble works too, but not my speakers proper.
But the Pebble app lets me set the music player to control, so I suspect it's passing through that and not registering as a standard keypress.

@SolidSnake cat /proc/mdstat
 
1:06 AM
@SolidSnake I think you mean @qasdfdsaq ;p
 
@qasdfdsaq No arrays showed.
 
Also, have you checked /dev/md?
 
Bob
@qasdfdsaq Galaxy S5 yea?
 
Bob
Thanks a bunch!
 
1:08 AM
Now just to figure out how to put my headset in pairing mode
 
@qasdfdsaq There's no /dev/md .
 
Well that was easy, literally do nothing.
As in, turn it on, and after a while it starts talking to you and says "Pairing mode on. Search for the headset from the bluetooth device. Enter 0000 if prompted for a PIN"
@Bob: Confirmed exact same behaviour via standard Bluetooth headset.
Incidentally, the call/redial button does work
 
Bob
Thanks!
 
So does holding down the call button to get voice commands/S-Voice. but I suspect that functionality is going through the HSP not the AVRCP profile.
 
Bob
@qasdfdsaq For actually making a phone call? Or does it do the search thing?
 
1:12 AM
Both. Pressing call brings up the dialler and calls the last dialled number. Holding call goes to S-Voice/Search
Basically standard Bluetooth headset behaviour
 
Bob
@qasdfdsaq The FF bug actually has nothing to do with AVRCP. It's intercepting (and swallowing) standard Android keypresses.
 
Also, even going to task switcher is enough to get the contrls working again.
 
Bob
@qasdfdsaq Interesting. I wonder if that falls under KEYCODE_SEARCH (which FF explicitly ignores)
 
@qasdfdsaq That was for me?
 
Yeah but I suspect the AVRCP stack just ends up sending Android keypresses.
@SolidSnake No
 
1:14 AM
@qasdfdsaq Sry. :S
 
Bob
@qasdfdsaq Yea, bringing up the keyboard works too. I'm near 100% sure of why it's happening now. Just gotta test (need *nix or OS X to build) and convince the Mozilla guy there.
@qasdfdsaq Yup, seems like it.
... :S
Hm. There's a KEYCODE_CALL. Wonder why that works :S
@qasdfdsaq ...TMI
 
@qasdfdsaq ._.
COULD BE WORSE

(Yea, I've actually been meaning to get some to make an eyedropper fountain pen.)
 
When I had a ghetto PoE router on the roof 3 floors above my flat, the rainwater kept on coming through the cabling and corroding my PoE injectors.
Splodge a bit of silicon grease in there and the problem was gone forever.
 
@qasdfdsaq and other things you'd do on a night out in dallas vegas?
 
@JourneymanGeek Shh. You know the rule. What happens in vegas...
 
> How to Remove Silicone Grease
A common need that arises for consumers is removing silicone grease. The following is a proven method to remove old grease that needs to be reapplied:

Step 1 – Mix 1/8 cup of mild dishwasher detergent into a half gallon of hot (not boiling) water.
OK I know this isn't going to work for my bluetooth headset already.
 
Bob
1:18 AM
LOL
I'd just go with isopropanol.
Removes just about everything liquid.
 
I'm pretty sure I've tried that before
(Unsuccessfully)
 
I'd try screen wipes
 
Bob
Hm... I suppose silicone grease isn't really liquid.
 
Also, as it turns out my carpet is also covered in silicone grease. It's actually quite effective against fleas.
Thanks to my flatmate's cats >_>
 
Bob
btw, that bug was reported by "ravi". Sounds familiar...
 
1:20 AM
I've spent the last couple hours identifying the girl pic in each of these videos as they come up :-/

but I don't have access to the host right now :\
 
FX?
 
Bob
1:26 AM
@qasdfdsaq Fx = 'preferred' abbreviation for Firefox
I'll probably go back to FF :\
 
@SolidSnake I suspect it's just not starting the md devices automagically
mdadm --start or mdadm --scan or some other voodoo for manually starting md-raid devices is what's needed

@qasdfdsaq since I'm in a VM deleted and recreated HDDs, trying to do everything from the CentOs live cd (even the mdadm creation).

Let's see.
 
Oh
Well in that case it's easy
 
@qas
 
Because the creation commands should auto-start them
I just can't remember what the commands are cause ever since I first created them they automatically got put in fstab

@JourneymanGeek So if you do it every year you get +2GB every year?
 
@qasdfdsaq assuming they do it every year
 
Well the article says:

lots of interesting news today
@qasdfdsaq THe resurrection ship is in the garage at the moment...
 
I was tempted to just clone it myself and run a clone of him
I think I recall allquixotic exporting John Cavill's config some time recently
 
Bob
@qasdfdsaq Cause I don't have a Linux desktop VM anymore.
 
Can't you compile it on Windows?
 
Bob
1:37 AM
Nup.
If I could I would've done that by now.
> Building Firefox for Android on Microsoft Windows is not yet supported. There is no hard reason that it should not be possible (now; in the past, it was not possible because Google did not release certain parts of the Android toolchain for Windows), but it's also not a priority.

Lame

I'm almost tempted to see if it can compile on a phone...
 
Ok. Created the RAID arrays but GUI is not seeing them
 
Just use Ubuntu xD
It all works on Ubuntu.
 
@qasdfdsaq

@qasdfdsaq Ahaha. Can't do that. I need to "refresh" something?
 
I'm going to bed
 
(sorry late night enters)
@qasdfdsaq Right. Thanks for your kind help anyway
 
I'm off to dream about Mellanox ConnectX-2 10GbE cards.
Nope, wrong image.
Nope, wrong image again. Though I wouldn't complain about dreaming about them.
Finally.

@qasdfdsaq 'night
 
1:51 AM
@qasdfdsaq that looks like my old 6405E.... but then, most PCIe cards with that kind of heatsink probably do
 
Bob
lol
I have a 100Mbit card lying around in a box somewhere. Completely useless now. Looks identical, apart from being PCI.
 
@JourneymanGeek think i have to run it on FF; it dies on phantomjs now
 
:(
(grumbles about the lack of proper chat API, which would make many nice things possible)

@allquixotic Does it work if you downgrade pjs again?
Also, turns out half a caffeine pill (100mg?) does a really good job of keeping me awake
Probably not particularly healthy.

I have an embedded board (the NVidia Jetson TK1 running Ubuntu) that is said to have a "RS232 Serial port routed to UART4", according to their spec sheet. If I want to access that interface from a C/C++ app, what docs should I be looking at? Should I expect that the RS232 port will be automatically mapped to a /dev/tty* device that I can write to, and if so what APIs should I access it with?
 
hm
(I have no idea. I can't even remember what we used to use to talk to serial ports at my last job)
 
That's not a good start ;)

Q: init, read and write for linux serial device with C

EmbedAt the moment i'm working on a new project where i want to make a connection with an FTDI which is connected to my debian machine. I am intending to write the code with C, not C++. Here lies my problem. All the examples i find are incomplete or are made for a c++ compliler in stead of the GCC com...

this feels like a good start...
 
Hmmmm... that seems workable. How might I register the device in the first place? I wouldn't be surprised if the /dev/ device isn't created until I manually set a proper mode somewhere.
It looks like that thread has enough to get me started. I can connect up the device and see if I can get a serial port configured via the command line; if so, that example should have everything I need. Thanks!
